Abstract
Description
Technical Field
[0001] This application relates to the field of electronic differential lock assembly technology, and in particular to a testing device for electronic differential locks. Background Technology
[0002] In recent years, electronic differential locks have been widely used as a technology to solve the problem of single-wheel slippage in complex road conditions. By controlling the vehicle's differential, it allows the vehicle to automatically adjust the speed of each wheel during driving, thereby preventing slippage and improving vehicle stability and safety. By monitoring wheel speeds through vehicle sensors, when single-wheel slippage occurs, the electronic control unit automatically adjusts the wheel speed, transferring power to the tire with the lower speed, thus enabling the vehicle to better adapt to road conditions, making it highly favored by OEMs.
[0003] During the assembly process, in order to ensure assembly accuracy, it is necessary to detect the actual distance between the electronic differential lock and the target object (named signal disc, made of magnetic material, whose position change can cause a change in magnetic field strength). However, the existing detection tools are not easy to use and cannot meet the requirements of high-precision detection, so there is room for improvement. Utility Model Content
[0004] To improve the accuracy of detecting the true distance between the electronic differential lock and the target object at the engagement position, this application provides a detection device for electronic differential locks.
[0005] The detection device for electronic differential locks provided in this application adopts the following technical solution: A detection device for an electronic differential lock includes a support plate detachably connected to the mounting shaft of the electronic differential lock. A vertically mounted fixing plate is fixedly installed on the support plate. A mounting base is detachably installed on the fixing plate. A micrometer is mounted on the mounting base. A sliding plate is adjustable in height on the fixing plate. A guide mechanism for limiting the vertical movement of the sliding plate is installed on the fixing plate. A position sensor is detachably installed on the sliding plate.
[0006] By adopting the above technical solution, the detection device can be installed on the electronic differential lock using a support plate. After the installation of the detection device is completed, the operator moves the position of the sliding plate so that the detection end of the position sensor is pressed against the target object. When the position sensor is pressed against the target object, the operator measures the position of the sliding plate with a micrometer, thereby achieving accurate detection of the true distance between the electronic differential lock and the target object at the engagement position.
[0007] Preferably, the support plate has a central insertion hole that matches the mounting shaft, and the side wall of the support plate has a through-hole for connecting screws. A tightening screw is threaded into the connecting screw hole, and the end face of the shank of the tightening screw abuts against the side wall of the mounting shaft.
[0008] By adopting the above technical solution, the support plate can be placed horizontally on the top end face of the electronic differential lock through the insertion hole. By tightening the screw, the position of the support plate can be positioned, preventing the support plate from rotating and affecting the detection accuracy.
[0009] Preferably, the guiding mechanism includes a movable guide rail fixedly mounted on a fixed plate, a slide rail having a slide along the axial direction, a slider fixedly mounted on the side wall of the sliding plate, and a protrusion adapted to the slider being integrally formed on the side wall of the slider.
[0010] By adopting the above technical solution, the sliding trajectory of the slider and the sliding block can be restricted by the moving guide rail, ensuring that the slider and the sliding plate slide up and down in the vertical direction, further guaranteeing the measurement accuracy of the detection device.
[0011] Preferably, the two sides of the protrusion are integrally formed with anti-detachment parts, and the two inner sidewalls opposite to the slide are provided with anti-detachment grooves along the axial direction that are adapted to the anti-detachment parts.
[0012] By adopting the above technical solution, and by using the anti-detachment part and the anti-detachment groove together, the occurrence of the slider detaching from the slide rail can be reduced, and the stability of the connection between the moving guide rail and the slider can be improved.
[0013] Preferably, a spring is provided between the slider and the mounting base, and the two ends of the spring are fixedly connected to the mounting base and the slider, respectively.
[0014] By adopting the above technical solution and using the spring, the connection between the slider and the mounting base can be realized. After the test is completed, the spring retracts and drives the slider and sliding plate to reset, which can improve the ease of use of the testing device.
[0015] In summary, the detection device for electronic differential locks provided in this application has at least the following beneficial technical effects: 1. The detection device can be installed on the electronic differential lock using the support plate. After the installation of the detection device is completed, the operator moves the position of the sliding plate so that the detection end of the position sensor is pressed against the target. When the position sensor is pressed against the target, the operator measures the position of the sliding plate with a micrometer to accurately detect the true distance between the electronic differential lock and the target. 2. The support plate can be placed horizontally on the top end face of the electronic differential lock through the insertion hole. The position of the support plate can be positioned by tightening the screw, so as to prevent the support plate from rotating and affecting the detection accuracy. 3. The sliding trajectory of the slider and sliding block can be restricted by the moving guide rail, ensuring that the slider and sliding plate slide up and down in the vertical direction, further ensuring the measurement accuracy of the detection device; 4. The spring design allows for connection between the slider and the mounting base. After the test is completed, the spring retracts, which can reset the slider and sliding plate, improving the ease of use of the testing device. Attached Figure Description

[0020] The following combination Figures 1-3 This application will be described in further detail.
[0021] Example This application discloses a detection device for an electronic differential lock. (Refer to...) Figure 1 and Figure 2 It mainly includes a support plate 2 that is detachably connected to the mounting shaft of the electronic differential lock 1. The support plate 2 is approximately shaped like a figure 6. The support plate 2 has a through hole 21 for the mounting shaft to pass through, and a connecting screw hole is through the side wall of the support plate 2. A tightening screw 22 is threaded into the connecting screw hole. The end face of the tightening screw 22 abuts against the side wall of the mounting shaft to prevent the support plate 2 from rotating on the electronic differential lock 1 and affecting the detection accuracy.
[0022] A vertically mounted fixing plate 3 is fixedly installed on the support plate 2 by welding. A mounting base 4 is detachably installed on the fixing plate 3 by bolts. The mounting base 4 is L-shaped and a micrometer 5 is mounted on the mounting base 4.
[0023] A slider 9 is slidably mounted on the fixed plate 3, and a guide mechanism for limiting the slider 9 to slide up and down in the vertical direction is installed on the fixed plate 3. A horizontally arranged sliding plate 6 is bolted to the side of the slider 9 away from the moving guide rail 8. The sliding plate 6 is located directly below the micrometer 5, and a contact position sensor 7 is fixedly mounted on the sliding plate 6.
[0024] Please refer to Figure 1 and Figure 3 In this embodiment, the guiding mechanism is a movable guide rail 8 welded and fixed on the fixed plate 3. The movable guide rail 8 has a slide rail 81. The slider 9 has a protrusion 91 integrally formed on the side away from the sliding plate 6. The protrusion 91 is slidably installed in the slide rail 81.
[0025] In some other embodiments, depending on the actual needs of use, a vertically arranged guide rod may also be installed on the fixed plate 3 to limit the sliding trajectory of the sliding plate 6, which will not be limited or elaborated here.
[0026] In order to prevent the slider 9 from detaching from the slide rail 81, in this embodiment, anti-detachment parts 92 are integrally formed on the opposite sides of the slider 9, and two anti-detachment grooves 82 that are adapted to the anti-detachment parts 92 are formed on the two opposite inner sidewalls of the slide rail 81 along the axial direction.
[0027] In addition, please refer to Figure 1 In this embodiment, a spring 10 is provided between the slider 9 and the mounting base 4, with the upper and lower ends of the spring 10 fixedly connected to the mounting base 4 and the slider 9, respectively. The spring 10 enables the connection between the slider 9 and the mounting base 4. Furthermore, after the detection is completed, the spring 10 retracts, causing the slider 9 and the sliding plate 6 to reset, thus improving the ease of use of the detection device.
[0028] The implementation principle of the detection device for an electronic differential lock 1 in this application embodiment is as follows: The support plate 2 can be installed on the top end face of the electronic differential lock 1 through the support plate 2 and the insertion hole 21 on the support plate 2. By tightening the screw 22, the support plate 2 can be prevented from rotating on the electronic differential lock 1, which would affect the subsequent measurement accuracy. After the detection device is installed on the electronic differential lock 1 through the support plate 2, the operator can hold the slider 9 and move the sliding plate 6 down together until the detection end of the position sensor 7 is pressed against the target object 11 on the electronic differential lock 1. Then, the operator can measure the position of the top end face of the sliding plate 6 with a micrometer 5 to obtain the true distance between the electronic differential lock 1 and the target object 11 with high accuracy.
[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
