下面结合附图具体描述本发明实施例的手持式尾气检测装置100。The handheld exhaustgas detection device 100 according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

根据本发明实施例的手持式尾气检测装置100包括反射器10、激光器20、支撑杆30、分析模块40和显示器50。The handheld exhaustgas detection device 100 according to the embodiment of the present invention includes areflector 10 , a laser 20 , asupport rod 30 , ananalysis module 40 and adisplay 50 .

具体而言，反射器10具有接收尾气的通道，通道的一侧设有安装孔11，通道与安装孔11相对的一侧设有反射部12，激光器20设在反射器10的一侧，激光器20的激光发射接收模块设于安装孔11以接收反射部12反射的光线，支撑杆30的一端与激光器20相连，分析模块40设在支撑杆30的另一端，分析模块40与激光器20连接以对激光器20接收的信号进行分析，分析模块40的外壳42的一侧设有适于手臂穿过的臂套41，显示器50设于分析模块40以显示分析结果。Specifically, thereflector 10 has a channel for receiving exhaust gas, a mountinghole 11 is provided on one side of the channel, a reflection portion 12 is provided on the side of the channel opposite to the mountinghole 11, and the laser 20 is provided on one side of thereflector 10. The laser emitting and receiving module 20 is arranged in the mountinghole 11 to receive the light reflected by the reflection part 12, one end of thesupport rod 30 is connected with the laser 20, theanalysis module 40 is arranged at the other end of thesupport rod 30, and theanalysis module 40 is connected with the laser 20 to To analyze the signal received by the laser 20 , anarm cover 41 suitable for the arm to pass through is provided on one side of the casing 42 of theanalysis module 40 , and adisplay 50 is provided in theanalysis module 40 to display the analysis result.

换句话说，根据本发明实施例的手持式尾气检测装置100，可以用于对车辆的尾气进行检测。反射器10为空心圆筒且两侧为平行平面结构，与激光器20相连一侧设有安装孔11，另一侧设有反射部12。激光器20与分析模块40通过支撑杆30相连，激光器20内部设置有激光发射接收模块。分析模块40上方安装有显示器50，下方设置有臂套41。In other words, the handheld exhaustgas detection device 100 according to the embodiment of the present invention can be used to detect the exhaust gas of a vehicle. Thereflector 10 is a hollow cylinder with parallel plane structures on both sides, a mountinghole 11 is provided on one side connected to the laser 20 , and a reflection portion 12 is provided on the other side. The laser 20 is connected with theanalysis module 40 through thesupport rod 30 , and a laser emitting and receiving module is arranged inside the laser 20 . Adisplay 50 is installed above theanalysis module 40, and anarm cover 41 is installed below.

其中需要说明的是，在使用手持式尾气检测装置100进行尾气检测的过程中，首先，操作者可以将手臂穿过臂套41握住支撑杆30，然后将反射器10放置在机动车尾气排放处，使得尾气可以顺利通过反射器10的通道。激光器20的激光发射接收模块发射激光，经过安装孔11到达反射部12，再经反射部12的反射，传回激光器20的接收模块。激光器20上的激光发射接收模块利用激光的准直度高、方向性好的特性，可以提高尾气检测的精准性。分析模块40通过分析处理得出结果，从而最终分析结果通过显示器50显示得出。It should be noted that, in the process of using the hand-held exhaustgas detection device 100 for exhaust gas detection, first, the operator can pass the arm through thearm cover 41 to hold thesupport rod 30, and then place thereflector 10 on the exhaust gas discharge of the motor vehicle. so that the exhaust gas can pass through the channel of thereflector 10 smoothly. The laser emitting and receiving module of the laser 20 emits laser light, passes through the mountinghole 11 to the reflection part 12 , and is reflected by the reflection part 12 , and then returns to the receiving module of the laser 20 . The laser transmitting and receiving module on the laser 20 utilizes the characteristics of high collimation and good directivity of the laser, which can improve the accuracy of exhaust gas detection. Theanalysis module 40 obtains a result through analysis processing, so that the final analysis result is obtained by displaying thedisplay 50 .

由此，根据本发明实施例的手持式尾气检测装置100，通过将反射器10、激光器20与分析模块40通过支撑杆相连，可以根据尾气检测的需要调整装置的相对位置，使得检测方便，易于操作，解决了携带不便、操作单一、使用程序复杂、导致操作者面临尾气影响的问题。Therefore, according to the handheld exhaustgas detection device 100 according to the embodiment of the present invention, by connecting thereflector 10, the laser 20 and theanalysis module 40 through the support rod, the relative position of the device can be adjusted according to the needs of exhaust gas detection, so that the detection is convenient and easy The operation solves the problems of inconvenient portability, single operation, complicated use procedures, and causing the operator to face the influence of exhaust gas.

根据本发明的一个实施例，反射器10为中空柱状，反射器10的相对两侧分别形成为平面，一个平面上设有安装孔11，另一个平面的内壁面设有反射部12。According to an embodiment of the present invention, thereflector 10 is a hollow column, and opposite sides of thereflector 10 are respectively formed as planes, one plane is provided with a mountinghole 11 , and the inner wall of the other plane is provided with a reflector 12 .

换句话说，反射器10为整个装置的最前端，也是与尾气直接接触的部分。反射器10为空心圆筒结构，而两侧设计为平面结构，从而便于安装孔11与激光器20以及另一侧反射部12的安装。安装孔11位于激光器20一侧，与之相对应的另一侧，反射部12安装在反射器10平面的内壁面。In other words, thereflector 10 is the front end of the entire device, and is also the part that is in direct contact with the exhaust gas. Thereflector 10 is a hollow cylindrical structure, and the two sides are designed as a plane structure, so as to facilitate the installation of the mountinghole 11 , the laser 20 and the reflecting portion 12 on the other side. The mountinghole 11 is located on one side of the laser 20 , and the other side corresponding to the mountinghole 11 is mounted on the inner wall surface of the reflector 10 plane.

由此，反射器10的中空柱状结构便于尾气顺利通过，而安装孔11与激光器20相连，便于激光的发射与返回。尾气通过反射器10同时穿过激光器20的激光发射接收模块发射出的激光，激光再经反射部12的反射，通过安装孔11返回激光器20的激光发射接收模块。当尾气经过激光时，激光部分会被遮挡，反射部12将这部分激光反射回激光器20的激光发射接收模块。Therefore, the hollow columnar structure of thereflector 10 facilitates the smooth passage of exhaust gas, and themounting hole 11 is connected to the laser 20 to facilitate the emission and return of the laser. The exhaust gas passes through thereflector 10 and simultaneously passes through the laser emitted by the laser emitting and receiving module of the laser 20 . When the exhaust gas passes through the laser, the laser part will be blocked, and the reflection part 12 reflects this part of the laser back to the laser emitting and receiving module of the laser 20 .

优选地，反射部12为反射镜。安装于反射器10内壁平面的反射镜达到将激光传回激光器20的效果，便于后续对尾气的分析处理。Preferably, the reflection part 12 is a reflection mirror. The reflector installed on the inner wall plane of thereflector 10 achieves the effect of transmitting the laser light back to the laser 20, which is convenient for subsequent analysis and processing of the exhaust gas.

进一步地，激光器20与反射器10的一个平面焊接相连。反射器10设有安装孔11的一侧设置为平面便于与激光器20相连，通过焊接的方式，使得反射器10与激光器20的连接更加牢固，防止在尾气检测的过程中，因人员操作不当而损坏装置。Further, the laser 20 is welded to a plane of thereflector 10 . The side of thereflector 10 with the mountinghole 11 is set to be flat so as to be connected to the laser 20. By welding, the connection between thereflector 10 and the laser 20 is made more firm, so as to prevent improper operation by personnel during the exhaust gas detection process. damage the device.

根据本发明的一个实施例，支撑杆30形成为沿其轴向可伸缩的伸缩杆，伸缩杆包括：内连接杆31和外连接杆32。According to an embodiment of the present invention, thesupport rod 30 is formed as a telescopic rod that is telescopic and retractable along its axial direction, and the telescopic rod includes: an inner connectingrod 31 and an outer connectingrod 32 .

其中，内连接杆31的一端与激光器20相连，外连接杆32的一端与内连接杆31的另一端可活动地相连，外连接杆32的另一端与分析模块40相连。One end of the inner connectingrod 31 is connected with the laser 20 , one end of the outer connectingrod 32 is movably connected with the other end of the inner connectingrod 31 , and the other end of the outer connectingrod 32 is connected with theanalysis module 40 .

换句话说，伸缩杆的长度可根据实际的检测环境以及车型而改变其长度，其包含有内、外两根连接杆。外连接杆32的内径略大于内连接杆31的内径，内连接杆31可伸缩到外连接杆32内部。外连接杆32的另一端与分析模块40通过镶嵌固定在分析模块40的外壳42。内连接杆31的另一端与激光器20通过旋转螺帽21相连。In other words, the length of the telescopic rod can be changed according to the actual detection environment and vehicle type, and it includes two connecting rods, an inner and an outer one. The inner diameter of the outer connectingrod 32 is slightly larger than the inner diameter of the inner connectingrod 31 , and the inner connectingrod 31 can be retracted into the interior of the outer connectingrod 32 . The other end of the outer connectingrod 32 and theanalysis module 40 are fixed to the casing 42 of theanalysis module 40 by inserting. The other end of the inner connectingrod 31 is connected with the laser 20 through the rotatingnut 21 .

由此，分析模块40与激光器20通过伸缩杆相连，伸缩杆由内连接杆31与外连接杆32组成。操作者在检测尾气的过程中，可以通过改变伸缩杆的长度来达到检测的目的，此过程避免了操作者近距离接触尾气，保证了操作的安全性以及舒适性。Thus, theanalysis module 40 is connected with the laser 20 through a telescopic rod, and the telescopic rod is composed of an inner connectingrod 31 and an outer connectingrod 32 . In the process of detecting the exhaust gas, the operator can achieve the purpose of detection by changing the length of the telescopic rod. This process avoids the operator's close contact with the exhaust gas and ensures the safety and comfort of the operation.

进一步地，伸缩杆还包括：连接器33。Further, the telescopic rod further includes: aconnector 33 .

其中，连接器33设于内连接杆31与外连接杆32的连接处，连接器33可活动以调节内连接杆31与外连接杆32之间的相对位置。Theconnector 33 is provided at the connection between the inner connectingrod 31 and the outer connectingrod 32 , and theconnector 33 is movable to adjust the relative position between the inner connectingrod 31 and the outer connectingrod 32 .

内连接杆31的一端通过连接器33与外连接杆32的一端相连，操作者可以通过调节连接器33，使内连接杆31伸缩到外连接杆32内，从而达到调节伸缩杆长度的目的。One end of the inner connectingrod 31 is connected with one end of the outer connectingrod 32 through theconnector 33, and the operator can adjust theconnector 33 to make the inner connectingrod 31 telescopic into the outer connectingrod 32, so as to achieve the purpose of adjusting the length of the telescopic rod.

根据本发明的一个实施例，内连接杆31的一端与激光器20可活动地相连，激光器20绕内连接杆31的轴线可转动。According to an embodiment of the present invention, one end of the inner connectingrod 31 is movably connected to the laser 20 , and the laser 20 is rotatable around the axis of the inner connectingrod 31 .

换句话说，激光器20与内连接杆31通过旋转螺帽21连接，激光器20可以根据检测的环境改变而旋转到指定的位置，使得尾气更顺利地通过反射器10。In other words, the laser 20 is connected with the inner connectingrod 31 by rotating thenut 21 , and the laser 20 can be rotated to a designated position according to the detected environmental change, so that the exhaust gas can pass through thereflector 10 more smoothly.

由此，内连接杆31与旋转螺帽21相连，使得激光器20可绕内连接杆31的轴线转动，从而达到根据不同的车型而改变激光器20位置的目的。Thus, the inner connectingrod 31 is connected with the rotatingnut 21, so that the laser 20 can rotate around the axis of the inner connectingrod 31, so as to achieve the purpose of changing the position of the laser 20 according to different vehicle models.

可选地，显示器50与臂套41设在外壳42的相对两侧，显示器50的显示面朝向用户所在方向倾斜延伸。Optionally, thedisplay 50 and thearm cover 41 are disposed on opposite sides of the housing 42, and the display surface of thedisplay 50 extends obliquely toward the direction of the user.

换句话说，分析模块40设有外壳42，臂套41与外壳42相连且位于分析模块40的下方。显示器50位于分析模块40的上部，且显示面朝向用户所在方向倾斜安置。In other words, theanalysis module 40 is provided with a housing 42 , and thearm cover 41 is connected to the housing 42 and located below theanalysis module 40 . Thedisplay 50 is located on the upper part of theanalysis module 40 , and the display surface is arranged obliquely toward the direction of the user.

由此，操作者可以将手臂深入臂套41内，使得检测过程更加稳固。而外壳42可以起到保护内部复杂电路的效果，避免外界的损坏。显示器50的朝向观察者一侧倾斜的设计，更加便于操作者观察分析结果。Thus, the operator can put his arm deep into thearm cover 41, so that the detection process is more stable. The casing 42 can protect the internal complex circuit and avoid external damage. The inclined design of thedisplay 50 toward the observer side makes it more convenient for the operator to observe the analysis results.

优选地，手持式尾气检测装置100还包括：握持手柄60。Preferably, the handheld exhaustgas detection device 100 further includes: agrip handle 60 .

其中，握持手柄60设在支撑杆上且与臂套41的位置相对应。操作者手臂可以穿过臂套41，手部握住握持手柄60。通过增加握持手柄60的设计，操作者可以在检测过程中长时间握持装置，使用更加便捷。操作者可以更自由的控制装置，随时可以根据车型的改变而改变检测装置的位置，从而可以达到更好的检测效果。当不需要使用时，携带也更加方便。The holdinghandle 60 is provided on the support rod and corresponds to the position of thearm cover 41 . The operator's arm can pass through thearm cover 41 , and the hand grips thegrip handle 60 . By adding the design of the holdinghandle 60, the operator can hold the device for a long time during the detection process, which is more convenient to use. The operator can control the device more freely, and can change the position of the detection device at any time according to the change of the vehicle model, so as to achieve a better detection effect. It is also more convenient to carry when not in use.
