本發明是有關於一種電動棘輪扳手，特別是指一種緊湊型電動棘輪扳手。The present invention relates to an electric ratchet wrench, and in particular to a compact electric ratchet wrench.
參閱圖1與圖2，說明美國專利公開號第US20220266439號專利案所揭露之一種習知的電動扳手1，主要包一頭部11、一連接於該頭部11的主體12、一安裝於該頭部11且用於輸出動力的輸出件13、一安裝在該主體12且用於轉換電能為動能的電機14、一安裝在該主體12且用於供應電能的電池單元15、一安裝在該頭部11與該主體12間的前蓋16、一套接於該前蓋16且用於傳遞動能的減速齒輪組17，及一可移動地設置在該頭部11與該主體12間且用於啟動該電機14的冠部18。該主體12包括一環繞該前蓋16與電機14且能夠提升結構強度的支撐管121，及一環繞該支撐管121且可供握持的把手122。1 and 2 illustrate a conventional electric wrench 1 disclosed in U.S. Patent Publication No. US20220266439, which primarily comprises a head 11, a main body 12 connected to the head 11, an output member 13 mounted on the head 11 for outputting power, a motor 14 mounted on the main body 12 for converting electrical energy into kinetic energy, a battery unit 15 mounted on the main body 12 for supplying electrical energy, a front cover 16 mounted between the head 11 and the main body 12, a reduction gear assembly 17 sleeved on the front cover 16 for transmitting kinetic energy, and a crown 18 movably disposed between the head 11 and the main body 12 for starting the motor 14. The main body 12 includes a support tube 121 that surrounds the front cover 16 and the motor 14 and enhances structural strength, and a handle 122 that surrounds the support tube 121 and provides for gripping.
惟，目前市面上的電動扳手為求較大的輸出功率，通常配備有較大輸出功率的電機14。由於較大輸出功率的電機14往往體積較大，再加上該前蓋16、該減速齒輪17與該支撐管121是由內層向外層，以層層套接的方式連接，因此，整體的長度與斷面的寬度也會一併變大，無法再進一步縮減，而不利於在狹小的空間中操作。However, electric wrenches currently on the market typically feature a high-output motor 14 in order to achieve higher output power. Since high-output motors 14 are often larger in size, and the front cover 16, reduction gear 17, and support tube 121 are connected from the inside out in a layered, sleeve-like arrangement, the overall length and cross-sectional width increase, preventing further reduction and making them difficult to operate in confined spaces.
因此，本發明之目的，即在提供一種配置緊湊的緊湊型電動棘輪扳手。Therefore, the object of the present invention is to provide a compact electric ratchet wrench with a compact configuration.

It is worth noting that the second axis Z substantially intersects the first axis X at right angles.
該軛頭32具有環繞該驅動頭31的一環齒部321，及一可被帶動且穿置在該頸部22內的作用部322。The yoke 32 has a toothed portion 321 surrounding the drive head 31 and an operating portion 322 that can be driven and inserted into the neck portion 22.
由於該動力輸出單元3為習知構造，且非本案技術特徵，本領域中具有通常知識者根據以上說明可以推知擴充細節，因此不多加說明。Since the power output unit 3 is a known structure and not a technical feature of this invention,the details will be inferred from the above description by those skilled in the art, and therefore will not be further explained.
參閱圖4、圖5與圖6，該柄身單元4沿該第一軸線X方向延伸且連接於該柄頭單元2的頸部22。該柄身單元4包括一環繞該第一軸線X且界定出一前置空間401與一中置空間402的支撐環41、一圍繞該支撐環41且界定出一後置空間403的套件42，及一迫緊環43。該前置空間401、該中置空間402與該後置空間403沿該第一軸線X方向排列，且該中置空間402連通於該前置空間401與該後置空間403。Referring to Figures 4, 5, and 6, the handle unit 4 extends along the first axis X and is connected to the neck portion 22 of the crown unit 2. The handle unit 4 includes a support ring 41 that surrounds the first axis X and defines a front space 401 and a center space 402, a sleeve 42 that surrounds the support ring 41 and defines a rear space 403, and a clamping ring 43. The front space 401, the center space 402, and the rear space 403 are arranged along the first axis X, and the center space 402 is connected to the front space 401 and the rear space 403.
該支撐環41具有一圍繞該前置空間401的前環段411，及一相反於該前環段411且圍繞該中置空間402的後環段412。該前環段411具有四個等角分佈且形成在內表面的肋槽413。該等肋槽413由該前環段411的一端緣沿該第一軸線X方向朝該後環段412延伸。該後環段412具有數個由外表面延伸至內表面的凹部414。The support ring 41 includes a front ring section 411 surrounding the front space 401 and a rear ring section 412 opposite the front ring section 411 and surrounding the central space 402. The front ring section 411 has four equiangularly spaced ribs 413 formed on its inner surface. The ribs 413 extend from one end edge of the front ring section 411 along the first axis X-direction toward the rear ring section 412. The rear ring section 412 has a plurality of recesses 414 extending from its outer surface to its inner surface.
參閱圖5、圖6與圖7，該套件42圍繞該支撐環41且界定出該後置空間403。在本實施例中，該套件42由二個殼體421相互對合而成且沿該第一軸線X方向延伸，並具有一環繞該第一軸線X的外周面420、數個形成在該等殼體421內表面且對合於該等凹部414的凸部422、二由該外周面420沿該第二軸線Z方向延伸且界定出一開口朝外的收納槽423的槽壁424，及二形成在該等槽壁424且沿該第二軸線Z方向延伸的限位槽425。藉此，通過該等凸部422與該等凹部414的結合關係，提升該套件42與該支撐環41的結構強度。Referring to Figures 5, 6, and 7, the sleeve 42 surrounds the support ring 41 and defines the rear space 403. In this embodiment, the sleeve 42 is formed by two mating shells 421 and extending along the first axis X. It comprises an outer circumferential surface 420 circumscribing the first axis X, a plurality of protrusions 422 formed on the inner surfaces of the shells 421 and corresponding to the recesses 414, two groove walls 424 extending from the outer circumferential surface 420 along the second axis Z and defining an outwardly opening receiving groove 423, and two retaining grooves 425 formed on the groove walls 424 and extending along the second axis Z. Thus, the structural strength of the sleeve 42 and the support ring 41 is enhanced through the engagement between the protrusions 422 and the recesses 414.
該迫緊環43螺合於該支撐環41的前環段411與該柄頭單元2的頸部22，使該柄身單元4沿該第一軸線X方向可卸離地連接於該柄頭單元2。The clamping ring 43 is screwed onto the front ring section 411 of the support ring 41 and the neck portion 22 of the crown unit 2, allowing the handle unit 4 to be detachably connected to the crown unit 2 along the first axis X direction.
參閱圖4、圖5與圖6，該電動單元5包括一電機51，及一傳動組52。Referring to Figures 4, 5, and 6, the electric unit 5 includes a motor 51 and a transmission assembly 52.

In this embodiment, the battery module 65 includes a battery 651 for supplying power to the motor 51, the control module 61, the detection switch 62, the first light-emitting element 63, and the second light-emitting elements 64. The battery 651 is a rechargeable lithium battery that stores electrical energy.
參閱圖4、圖5與圖7，該顯示元件66安裝在該套件42，並具有四個沿該第一軸線X方向排列且可透光的窗格661，及四個導光條662。每一該導光條662由各別的窗格661延伸至各別的第二發光元件64，用於導引各別的第二發光元件64所發射的光束朝各別的窗格661行進。Referring to Figures 4, 5, and 7, the display device 66 is mounted on the assembly 42 and comprises four light-transmissive panes 661 arranged along the first axis X, and four light-guiding strips 662. Each light-guiding strip 662 extends from a respective pane 661 to a respective second light-emitting element 64, guiding the light beam emitted by the respective second light-emitting element 64 toward the respective pane 661.
該扳機67樞接於該套件42且可移動地設置在該收納槽423。該扳機67且鄰近該前置空間401，並具有二形成在二側且滑合於該等限位槽425的擋止部671，及一沿該第二軸線Z方向朝該偵測開關62延伸的觸控部672。該扳機67在一迫壓位置(如圖8)與一常態位置(如圖2)間擺動，在該迫壓位置時，該扳機67的觸控部672迫壓於該偵測開關62，在該常態位置時，該扳機67的觸控部672遠離該偵測開關62且與該第一軸線X相隔一第二夾角θ2。該第二夾角θ2介於2度~5度，較佳的，為3度。The trigger 67 is pivotally connected to the housing 42 and movably disposed in the receiving slot 423. The trigger 67 is adjacent to the front space 401 and has two stoppers 671 formed on either side that slidably engage the stoppers 425, and a contact portion 672 that extends along the second axis Z toward the detection switch 62. The trigger 67 swings between a pressing position (as shown in FIG. 8 ) and a normal position (as shown in FIG. 2 ). In the pressing position, the contact portion 672 of the trigger 67 presses against the detection switch 62. In the normal position, the contact portion 672 of the trigger 67 is spaced away from the detection switch 62 and spaced apart from the first axis X by a second angle θ2. The second angle θ2 is between 2 degrees and 5 degrees, preferably 3 degrees.
該彈性元件68安裝在該套件42與該扳機67間，恆產生使該扳機67位於該常態位置的彈力。The elastic element 68 is installed between the assembly 42 and the trigger 67, and constantly generates an elastic force that keeps the trigger 67 in the normal position.
值得說明的是，該控制模組61能夠根據該感測訊號啟動該電機51與該第一發光元件63，且在失去該感測訊號後關閉該電機51，及於計數一發光延遲時間後，關閉該第一發光元件63。該發光延遲時間可以是10秒，但不以此為限。It is worth noting that the control module 61 can activate the motor 51 and the first light-emitting element 63 based on the sensing signal, and shut down the motor 51 after the sensing signal is lost. Furthermore, the control module 61 can shut down the first light-emitting element 63 after counting a light-emitting delay time. The light-emitting delay time can be, but is not limited to, 10 seconds.
參閱圖3、圖7與圖9，該控制模組61還能夠根據該電池模組65的電量，在顯示電量時，啟動對應的第二發光元件64。該電池模組65的電量與被啟動的第二發光元件64的數量成正比。舉例來說，該電池模組65的電量為等差數列，包括25%、50%、75%,及100%，當電量為100%時，該控制模組61會啟動4個第二發光元件64。藉此，每一該第二發光元件64發射的光束就會沿著各別的導光條662朝各別的窗格661行進，使4個窗格661全部顯示亮光。當電量為75%時，該控制模組61會啟動3個第二發光元件64，當電量為50%時，該控制模組61會啟動2個第二發光元件64，當電量為25%時，該控制模組61會啟動1個第二發光元件64，當電量為0%時，該等第二發光元件64都不會發射光束。Referring to Figures 3, 7, and 9, the control module 61 can also activate corresponding second light-emitting elements 64 based on the battery module 65's charge level when displaying the battery level. The battery module 65's charge level is proportional to the number of activated second light-emitting elements 64. For example, if the battery module 65's charge level follows an arithmetic progression, including 25%, 50%, 75%, and 100%, then when the charge level reaches 100%, the control module 61 will activate four second light-emitting elements 64. Consequently, the light beam emitted by each second light-emitting element 64 travels along its respective light guide bar 662 toward its respective window pane 661, causing all four window panes 661 to illuminate. When the battery level is 75%, the control module 61 activates three second light-emitting elements 64. When the battery level is 50%, the control module 61 activates two second light-emitting elements 64. When the battery level is 25%, the control module 61 activates one second light-emitting element 64. When the battery level is 0%, none of the second light-emitting elements 64 emit light beams.
參閱圖3、圖4、圖7與圖8，值得說明的是，該柄身單元4還界定有一沿該第一軸線X方向延伸的最大握持長度L1，且與該柄頭單元2界定有沿該第一軸線X方向延伸的最大總長度L2。該套件42沿該第二軸線Z方向所截取的斷面界定有一介於該外周面420間且通過該中置空間402與該發光元件63的最大徑寬H。Referring to Figures 3, 4, 7, and 8, it is worth noting that the handle unit 4 also defines a maximum gripping length L1 extending along the first axis X, and defines a maximum total length L2 with the crown unit 2 along the first axis X. A cross-section of the assembly 42 taken along the second axis Z defines a maximum diameter H between the outer peripheral surface 420 and passing through the central space 402 and the light-emitting element 63.
該最大握持長度L1介於145mm~155mm，較佳的，為150mm。該最大總長度L2介於210mm~220mm，較佳的，為215mm。該最大徑寬H介於34mm~46mm，較佳的，該最大徑寬H介於40mm~46mm。在本實施例中，該最大徑寬H為44mm。The maximum grip length L1 is between 145mm and 155mm, preferably 150mm. The maximum total length L2 is between 210mm and 220mm, preferably 215mm. The maximum diameter H is between 34mm and 46mm, preferably 40mm and 46mm. In this embodiment, the maximum diameter H is 44mm.
該最大握持長度L1與該最大徑寬H的比值介於3~4.2，較佳的，比值介於3~4。該最大總長度L2與該最大徑寬H的比值介於4.5~6，較佳的，為5.1。The ratio of the maximum gripping length L1 to the maximum diameter H is between 3 and 4.2, with a preferred ratio of 3 to 4. The ratio of the maximum total length L2 to the maximum diameter H is between 4.5 and 6, with a preferred ratio of 5.1.
應當注意的是，該最大徑寬H不限於通過該中置空間402與該第一發光元件63，在本實施例的其它變化例中，也可以如圖8所示通過該後置空間403。值得說明的是，通過該中置空間402的最大徑寬H略大於通過該後置空間403的最大徑寬H，但不影響與該最大握持長度L1或與該最大總長度L2的比值。It should be noted that the maximum diameter H is not limited to passing through the central space 402 and the first light-emitting element 63. In other variations of this embodiment, it can also pass through the rear space 403, as shown in Figure 8. It is worth noting that the maximum diameter H passing through the central space 402 is slightly larger than the maximum diameter H passing through the rear space 403, but this does not affect the ratio to the maximum gripping length L1 or the maximum total length L2.
當使用者握持該柄身單元4，並以握持該柄身單元4的手指握壓該扳機67位於該迫壓位置時，該觸控部672就會迫壓該偵測開關62輸出該感測訊號。藉此，該控制模組61就會根據該感測訊號啟動該電機51與該第一發光元件63。When a user grips the handle unit 4 and presses the trigger 67 to the pressing position with their fingers, the touch panel 672 presses the detection switch 62 to output the sensing signal. The control module 61 then activates the motor 51 and the first light-emitting element 63 based on the sensing signal.
此時，該第一發光元件63就會朝該第二軸線Z的方向發射光束，使照明範圍能夠涵蓋位於該驅動頭31下方的螺栓或螺母(圖未示)，而達到照明的目的。At this time, the first light-emitting element 63 will emit a light beam in the direction of the second axis Z, so that the illumination range can cover the bolts or nuts (not shown) located below the drive head 31, thereby achieving the purpose of illumination.
且該電機51會通過該傳動組52傳遞動力，而驅動該軛頭32的作用部322左、右偏擺，且在該軛頭32左、右偏擺的過程中，以該環齒部321帶動該驅動頭31以該第二軸線Z為中心單向轉動，進而通過電動力達到擰緊、或鬆釋螺栓或螺母(圖未示)的目的。The motor 51 transmits power through the transmission assembly 52, driving the active portion 322 of the tack 32 to oscillate left or right. During this oscillation, the annular tooth 321 drives the drive head 31 to rotate unidirectionally about the second axis Z, thereby tightening or loosening a bolt or nut (not shown) through electric force.
當使用者鬆釋該扳機67，且該扳機67位於該常態位置時，該控制模組61就會因為失去該感測訊號，而立即關閉該電機51，且計數10秒的發光延遲時間後，關閉該第一發光元件63。When the user releases the trigger 67 and the trigger 67 is in the normal position, the control module 61 loses the sensing signal and immediately shuts down the motor 51. After counting the 10-second delay time, the first light-emitting element 63 is turned off.
經由以上的說明，可將前述實施例的優點歸納如下：Based on the above description, the advantages of the aforementioned embodiments can be summarized as follows:
1、本發明不但能夠以該支撐環41提升結構強度，且能夠以該支撐環41無段差及緊湊的空間配置，縮短該最大握持長度L1與該最大總長度L2，及縮小該最大徑寬H。藉此，不但能夠縮小整體的體積，且能夠提升空間效益，而適用於在狹小的空間中移動。1. The present invention not only enhances structural strength with the support ring 41, but also shortens the maximum grip length L1 and the maximum total length L2, and reduces the maximum diameter H, thanks to the support ring 41's seamless and compact design. This not only reduces the overall volume but also improves space efficiency, making it suitable for maneuvering in confined spaces.
2、使用者只需以握持該柄身單元4的手指觸壓該扳機67，就能夠啟動該電機51，不但操作容易且順手。2. The user only needs to press the trigger 67 with the finger holding the handle unit 4 to start the motor 51, which is not only easy and convenient to operate.
3、且本發明能夠通過該第一發光元件63兼具有照明功能，進而提升使用上的實用性。3. The present invention can also provide lighting functions through the first light-emitting element 63, thereby improving practicality.
