背景技术Background technique

动力工具在使用的过程中，经常需要在一些昏暗、狭小的地方作业，因此会在动力工具的端部设置光源装置，从而便于用户在一些昏暗的地方进行作业，但是目前市面上的动力工具，因其端部设置复杂的结光源装置，造成动力工具端部在径向上较为冗长，这样会使用户在狭窄的地方进行作业时，容易会使用户的视线被阻挡，从而造成不便。During the use of power tools, it is often necessary to work in some dark and narrow places.

反射元件24固定设置在动力工具100内，反射元件24包括反射面241，反射面241用于将光源装置20出射的光线反射至朝向工作区域142，这样设置，可以使导光板21向四周漫射的光线反射至工作区域142，提高工作区域142内光线的效果。反射元件24设置在动力工具100内，即反射元件24可以固定设置在机壳11上，或者是机壳11内，在本实施例中，反射元件24与齿轮箱13固定连接或者一体成型，其中需要注意的是，反射元件24与齿轮箱13固定连接指的是，反射元件24与齿轮箱13之间保持相对固定，但是反射元件24与齿轮箱13两者之间并不是采用同一材质制成，具体的，反射元件24与齿轮箱13之间可以是采用吸附、涂装、电镀等方式使其两者之间保持固定。进一步的，反射元件24可以是油漆、涂层或是其他材质制成，在此并不限制其具体材质，只要能否够实现反射面241将光线反射至工作区域142即可。作为另一种优选的实施方式，齿轮箱13与反射元件24一体成型，即齿轮箱13形成反射元件24，也可以说是，反射面241由齿轮箱13形成，这样设置结构简单，且易于实现。Thereflective element 24 is fixedly arranged in thepower tool 100, thereflective element 24 includes areflective surface 241, and thereflective surface 241 is used to reflect the light emitted by thelight source device 20 toward the workingarea 142, so that thelight guide plate 21 can be diffused around The light reflected to the workingarea 142 improves the effect of the light in the workingarea 142 . Thereflective element 24 is arranged in thepower tool 100, that is, thereflective element 24 can be fixedly arranged on thecasing 11, or in thecasing 11. In this embodiment, thereflective element 24 is fixedly connected or integrally formed with thegear box 13, wherein It should be noted that the fixed connection between thereflective element 24 and thegear box 13 means that thereflective element 24 and thegear box 13 remain relatively fixed, but thereflective element 24 and thegear box 13 are not made of the same material Specifically, thereflective element 24 and thegear case 13 may be fixed by means of adsorption, painting, electroplating and the like. Further, thereflective element 24 can be made of paint, coating or other materials, and the specific material is not limited here, as long as thereflective surface 241 can reflect the light to the workingarea 142 . As another preferred embodiment, thegear box 13 and thereflective element 24 are integrally formed, that is, thegear box 13 forms thereflective element 24, and it can also be said that thereflective surface 241 is formed by thegear box 13, which is simple in structure and easy to implement. .

在本实施例中，齿轮箱13形成有安装槽1311，光源装置20至少部分设置在安装槽1311内。具体的，第一齿轮箱131在靠近工作区域142形成有向远离工作区域142凹陷的安装槽1311，导光板21至少部分安装在安装槽1311内。反射元件24与齿轮箱13一体成型，反射面241由安装槽1311的槽壁与槽底形成。这样设置，安装槽1311不但能定位导光板21，还能将导光板21漫射出的光线反射至工作区域142内，提高工作区域142内的亮度。进一步地，安装槽1311的槽壁及槽底的粗糙度低于1.6，这样设置可以使第一齿轮箱131的上的反射面241产生镜面的效果，提高了光的折射次数，增加了光的亮度。作为另一种可行的实施方式，如图14所示，也可以在安装槽1311内安装数个发光元件，发光元件呈环状分布在安装槽1311内，这样设置使发光元件发射出的光线直接照射在工作区域142内，而部分漫射的光线经过反射面241反射至工作区域142，从而提高工作区域142光线的亮度，这样用户在一些光线不足的区域，通过光源装置光线的补足，能够有效的解决用户带加工的区域光线不足的情况，提高了用户的工作效率。In this embodiment, thegear box 13 is formed with a mountinggroove 1311 , and thelight source device 20 is at least partially disposed in the mountinggroove 1311 . Specifically, thefirst gear box 131 is formed with a mountinggroove 1311 recessed away from the workingarea 142 near the workingarea 142 , and thelight guide plate 21 is at least partially mounted in the mountinggroove 1311 . Thereflection element 24 is integrally formed with thegear box 13 , and thereflection surface 241 is formed by the groove wall and the groove bottom of theinstallation groove 1311 . In this way, theinstallation groove 1311 can not only position thelight guide plate 21 , but also reflect the light diffused by thelight guide plate 21 into the workingarea 142 to improve the brightness of the workingarea 142 . Further, the roughness of the groove wall and groove bottom of theinstallation groove 1311 is lower than 1.6, so that thereflective surface 241 on thefirst gear box 131 can produce a mirror effect, which improves the refraction times of light and increases the light intensity. brightness. As another feasible implementation mode, as shown in Figure 14, several light-emitting elements can also be installed in theinstallation groove 1311, and the light-emitting elements are distributed in theinstallation groove 1311 in a ring shape, so that the light emitted by the light-emitting elements can directly Irradiated in the workingarea 142, and part of the diffused light is reflected to the workingarea 142 through thereflective surface 241, thereby improving the brightness of the light in the workingarea 142, so that the user can effectively use the supplementary light of the light source device in some areas where the light is insufficient. It solves the situation of insufficient light in the area where the user belt is processed, and improves the work efficiency of the user.

Specifically, thecircuit board 23 at least partially surrounds the light guide plate Circumferential arrangement of thelight board 21 . That is to say, thecircuit board 23 can be arranged at any position in the circumferential direction around the axis.

导光板21基本沿一轨迹延伸，发光元件设置在导光板21的周向上。导光板21在沿轨迹延伸的方向上具有第一光入射面和第二光入射面，发光元件通过第一光入射面和第二光入射面将光线引导至导光板中。其中，第一光入射面和第二光入射面之间在沿左右方向上的最大距离L大于等于0mm小于等于7mm。通过将第一光入射面与第二光入射面之间的距离L设置在上述范围内，可以尽可能的使导光板21出射至墙面的光线能够呈现出近乎于完整的环状，开阔用户的视野，提高用户操作的便利性。其中需要注意的是，本申请中轨迹并不限定是什么形状，即可以是圆形、C形、U形、多边形等。Thelight guide plate 21 basically extends along a track, and the light emitting elements are arranged in the circumferential direction of thelight guide plate 21 . Thelight guide plate 21 has a first light incident surface and a second light incident surface in the direction extending along the track, and the light-emitting element guides light into the light guide plate through the first light incident surface and the second light incident surface. Wherein, the maximum distance L between the first light incident surface and the second light incident surface along the left-right direction is greater than or equal to 0 mm and less than or equal to 7 mm. By setting the distance L between the first light-incident surface and the second light-incident surface within the above range, the light emitted from thelight guide plate 21 to the wall can be shown as nearly a complete ring as much as possible, opening up the space for users. The field of view improves the convenience of user operation. It should be noted that the shape of the trajectory in this application is not limited, that is, it may be circular, C-shaped, U-shaped, polygonal, etc.

作为一种具体的实施方式，导光板21沿一轨迹延伸，上述轨迹基本呈C形，具体的，该轨迹呈圆弧形。发光元件22设置在导光板21的端部，导光板21沿上述曲线方向形成有第一光入射面211和第二光入射面212，发光元件22通过第一光入射面211和第二光入射面212将光线引导至导光板21中。其中，第一光入射面211和第二光入射面212之间在沿左右方向上的最大距离L大于等于0.7mm小于等于5mm。也就是说导光板21围绕动力输出件14近似呈一圆环型，这样光出射面213射出的光线近乎为一个圆环形，从而能够消除动力输出件14或者是其他的工件等对工作区域142造成的影响，使用户更加方便的观察工作区域142。As a specific implementation manner, thelight guide plate 21 extends along a track, the track is substantially C-shaped, and specifically, the track is arc-shaped. The light-emittingelement 22 is arranged on the end of thelight guide plate 21. Thelight guide plate 21 is formed with a firstlight incident surface 211 and a secondlight incident surface 212 along the above-mentioned curved direction, and the light-emittingelement 22 passes through the firstlight incident surface 211 and the second light incident surface. Thesurface 212 guides light into thelight guide plate 21 . Wherein, the maximum distance L between the firstlight incident surface 211 and the secondlight incident surface 212 along the left-right direction is greater than or equal to 0.7 mm and less than or equal to 5 mm. That is to say, thelight guide plate 21 is approximately in the shape of a ring around thepower output member 14, so that the light emitted from thelight exit surface 213 is almost in a ring shape, thereby eliminating the impact of thepower output member 14 or other workpieces on the workingarea 142. As a result, the user can observe the workingarea 142 more conveniently.

导光板21在左右方向上的长度小于齿轮箱13在左右方向上的长度，也就是说导光板21基本内嵌在齿轮箱13内，这样设置可以使光出射面213出射的光线尽可能的靠近工作区域142，保证工作区域142的照明效果。而且还合理利用的齿轮箱13在前后方向的空间，在缩短轴向齿轮箱13的同时还缩短了长度方向上的尺寸，使动力工具100的结构更加小巧化。The length of thelight guide plate 21 in the left and right direction is smaller than the length of thegear box 13 in the left and right direction, that is to say, thelight guide plate 21 is basically embedded in thegear box 13, so that the light emitted from thelight exit surface 213 can be as close as possible to thelight guide plate 213. The workingarea 142 ensures the lighting effect of the workingarea 142 . Moreover, the space in the front and rear directions of thegear box 13 is also rationally utilized, shortening the size of theaxial gear box 13 and shortening the length direction at the same time, so that the structure of thepower tool 100 is more compact.

In this embodiment, the distance D between the firstlight emitting element 221 and the second light emitting element 222 along the direction perpendicular to the firststraight line 103 is greater than or equal to 0.5 mm and less than or equal to 7 mm. By setting the distance D between the first light-emittingelement 221 and the second light-emitting element 222 within the above-mentioned range, it is possible to make the light emitted by thelight guide plate 21 nearly form a ring on a plane perpendicular to the light-emittingsurface 213 Shape, broaden the user's field of vision, improve the convenience of user operation. Further, the distance D between the first light-emittingelement 221 and the second light-emitting element 222 along the direction perpendicular to the firststraight line 103 is greater than or equal to 0.8 mm and less than or equal to 3 mm, so that the light effect of the power tool is better. Specifically, the first light-emittingelement 221 and the second light-emitting element 222 are LED lamps, which can not only ensure the brightness of the light emitted by thelight guide plate 21, but also reduce the distance between the firstlight incident surface 211 and the secondlight incident surface 212. The distance between them makes the light emitted by thelight guide plate 21 basically form a complete circular ring, which increases the irradiation area of the light.
