Technical Field
[0001] This utility model belongs to the field of automotive component quality inspection technology, and in particular relates to an electronic gear shift lever quality inspection device. Background Technology
[0002] An electronic gear shift lever, also known as an electronic shift paddle or electronic shifter, is a digital gear shifting device in modern automobiles that replaces traditional mechanical manual or automatic transmissions. The electronic gear shift lever controls the shifting process through electronic sensors and an electric motor, and is typically a rocker arm type. During the manufacturing process of an electronic gear shift lever, its strength and quality must be tested to ensure its service life meets standards.
[0003] A search revealed a current lack of a dedicated device for testing the strength and quality of electronic gear shift levers. During pressure testing, the lack of a stable positioning structure allows the electronic gear shift lever to easily shift, affecting the testing process. Therefore, there is an urgent need to improve existing electronic gear shift lever quality testing devices and provide one with a clamping and positioning function. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a reasonably designed, simple structure, clamping and positioning function, and widely applicable electronic gear shift lever quality inspection device, thereby solving the problems existing in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An electronic gear shift lever quality inspection device includes a base plate, a controller, and a pressure sensor. The controller is fixedly installed on the upper right side of the base plate, and two support platforms are provided on the upper left side of the base plate. The top of each support platform has a groove structure, and the inner bottom surface of the groove structure has a sliding groove. A first positioning component is installed in the sliding groove. A bracket is fixed on the upper left side of the base plate, and a second positioning component is provided on the top left end of the bracket. The second positioning component is located directly above the left support platform. A third electric push rod is fixed at the middle of the top of the bracket. A sleeve is fixedly connected to the telescopic end of the third electric push rod. A pressure block is slidably provided in the sleeve, and a pressure sensor is fixedly provided between the top of the pressure block and the sleeve.
[0007] In a preferred embodiment, the two support platforms are arranged symmetrically about the bracket. The bottom end of the right support platform is symmetrically fixed with a first electric push rod. The bottom ends of the two first electric push rods and the bottom end of the left support platform are all fixed to the upper surface of the base plate.
[0008] In a preferred embodiment, the first positioning component includes a servo motor, a bidirectional lead screw, a slider, a column, and a rubber sleeve. The servo motor is fixedly installed on the outer wall of the top rear of the support platform. The bidirectional lead screw is rotatably installed in a slide groove. The rear end of the bidirectional lead screw is fixedly connected to the output end of the servo motor. Sliders are threaded onto the outer sides of the opposite ends of the threads of the bidirectional lead screw. A column is fixed to the upper end of each of the two sliders. A rubber sleeve is adhesively fitted onto the outer side of the column.
[0009] In a preferred embodiment, both sliders are engaged and slidably located within the groove, and the two sliders are linked together with their sliding directions always being opposite to each other.
[0010] In a preferred embodiment, the second positioning component includes a second electric push rod, a fixing block, a clamping rod, and a coil spring. The second electric push rod is fixedly installed on the top left end of the bracket. The telescopic end of the second electric push rod is fixedly connected to the fixing block. The clamping rod is installed on the inner side of the bottom center of the fixing block via a coil spring.
[0011] In a preferred embodiment, the longitudinal section of the fixing block is an inverted "U" shape, and the longitudinal section of the clamping rod is an inverted "V" shape.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In the solution of this utility model:
[0014] The servo motor is started to rotate the bidirectional lead screw, controlling the two sliders to slide synchronously and move closer to each other. This allows the two columns to clamp one end of the electronic shift handle. The two sets of first positioning components on the left and right can initially clamp both ends of the electronic shift handle. Then, the second electric push rod controls the fixing block and the clamping rod to move vertically downward. When one end of the clamping rod contacts the outer wall of the handle, as the fixing block continues to move downward, the clamping rod rotates so that the other end contacts the outer wall of the handle. The first and second positioning components work together to achieve stable positioning of the electronic shift handle, ensuring the stability of the electronic shift handle during the pressure test and facilitating the smooth progress of the test.
[0015] The right support platform is fixedly installed on the telescopic end of the first electric push rod to facilitate the height adjustment of the right support platform, making it easier to control the electronic shift lever to be tested to be in a horizontal state. This allows the device to be used for positioning electronic shift levers of different models, shapes and sizes, making the device more widely applicable and more practical.

[0024] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:
[0025] like Figure 1-5 As shown, the electronic gear shift lever quality inspection device of this utility model includes a base plate 1, a controller 2, and a pressure sensor 11. The controller 2 is fixedly installed on the upper right side of the base plate 1. Two support platforms 3 are provided on the upper left side of the base plate 1. The top of each support platform 3 is provided with a groove structure. The inner bottom surface of the groove structure is provided with a sliding groove 5. A first positioning component 6 is installed in the sliding groove 5. A bracket 7 is fixed on the upper left side of the base plate 1. A second positioning component 8 is provided on the top left end of the bracket 7. The second positioning component 8 is located directly above the left support platform 3. A third electric push rod 9 is fixedly fixed at the middle of the top of the bracket 7. A sleeve 10 is fixedly connected to the telescopic end of the third electric push rod 9. A pressure block 12 is slidably provided in the sleeve 10. A pressure sensor 11 is fixedly provided between the top of the pressure block 12 and the sleeve 10.
[0026] Based on the above structure, the two support platforms 3 are arranged symmetrically about the bracket 7. The bottom of the right support platform 3 is symmetrically fixed with the first electric push rod 4. The bottom of the two first electric push rods 4 and the bottom of the left support platform 3 are both fixed to the upper surface of the base plate 1.
[0027] In this embodiment, the first electric push rod 4 is used to facilitate the adjustment of the height of the right support platform 3, making the device suitable for positioning electronic shift levers of different models, shapes and sizes.
[0028] Based on the above structure, the first positioning component 6 includes a servo motor 61, a bidirectional lead screw 62, a slider 63, a column 64, and a rubber sleeve 65. The servo motor 61 is fixedly installed on the outer wall of the top rear of the support platform 3. The bidirectional lead screw 62 is rotatably installed in the slide groove 5. The rear end of the bidirectional lead screw 62 is fixedly connected to the output end of the servo motor 61. The two ends of the bidirectional lead screw 62 are threaded with sliders 63 on the outer side at opposite ends. The upper ends of the two sliders 63 are fixed with columns 64. The outer side of the columns 64 is adhesively fitted with rubber sleeves 65.
[0029] Based on the above structure, both sliders 63 are engaged and slide within the groove 5, and the two sliders 63 are linked together and their sliding directions are always opposite to each other.
[0030] In this embodiment, the servo motor 61 controls the bidirectional lead screw 62 to rotate, which allows the two sliders 63 to drive the two columns 64 to slide synchronously and move closer together, thereby clamping one end of the electronic shift handle. The left and right sets of first positioning components 6 can be used to initially clamp both ends of the electronic shift handle.
[0031] Based on the above structure, the second positioning component 8 includes a second electric push rod 81, a fixing block 82, a clamping rod 83, and a coil spring 84. The second electric push rod 81 is fixedly installed on the top left end of the bracket 7. The telescopic end of the second electric push rod 81 is fixedly connected to the fixing block 82. The clamping rod 83 is installed on the inner side of the bottom center of the fixing block 82 through the coil spring 84.
[0032] Based on the above structure, the longitudinal section of the fixing block 82 is an inverted "U" shape, and the longitudinal section of the clamping rod 83 is an inverted "V" shape.
[0033] In this embodiment, the second electric push rod 81 can control the fixed block 82 to move down. When one end of the pressing rod 83 abuts against the outer wall of the handle shift lever, as the fixed block 82 continues to move down, the pressing rod 83 can rotate so that the other end abuts against the outer wall of the handle shift lever, which facilitates cooperation with the first positioning component 6 to achieve stable positioning of the electronic shift lever and ensure that subsequent pressure testing is carried out smoothly and stably.
[0034] The working principle of this utility model is as follows:
[0035] In use, firstly, place both ends of the electronic shift handle to be tested above the two support platforms 3, and start the servo motor 61 to rotate the bidirectional lead screw 62. Control the two sliders 63 to drive the two columns 64 to slide stably along the slide groove 5 and move closer to each other. The two sets of first positioning components 6 on the left and right can be used to initially clamp the two ends of the electronic shift handle. Then, the second electric push rod 81 can be started to control the fixing block 82 and the clamping rod 83 to move vertically downward. When one end of the clamping rod 83 touches the outer wall of the handle shift lever, as the fixing block 82 continues to move downward, the clamping rod 83 can be pressed and rotated, causing its other end to touch the outer wall of the handle shift lever. The first positioning component 6 and the second positioning component 8 cooperate with each other to achieve stable positioning of the electronic shift handle, thereby ensuring the stability of the electronic shift handle during the pressure test and facilitating the smooth progress of the test.
[0036] After the electronic shift lever is securely clamped, the third electric push rod 9 can be activated to control the sleeve 10 and the pressure block 12 to move down and apply pressure to the handle part of the electronic shift lever. The pressure sensor 11 can be used to read the pressure value, which is convenient for detecting the quality of the electronic shift lever.
[0037] The first electric push rod 4 facilitates the adjustment of the height of the right support platform 3, making it easy to control the electronic shift lever to be tested to be in a horizontal state. This makes the device suitable for positioning electronic shift levers of different models, shapes and sizes, and the device has a wider range of applications and is more practical.
[0038] It should be noted that this device is powered by an external power source. The controller 2, the first electric push rod 4, the servo motor 61, the second electric push rod 81, the third electric push rod 9, and the pressure sensor 11 in the solution are all existing products. Their specific working principles and operation methods all adopt mature technologies, so they will not be described in detail.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
