Technical Field

[0001] This utility model belongs to the field of vehicle quality inspection technology, and in particular relates to a gear shift lever life testing machine. Background Technology

[0002] An automobile is a common and important means of transportation, typically composed of components such as an engine, chassis, body, and electrical system. It is powered by fuel or electricity, enabling independent movement on land, and is primarily used for transporting people or goods. The gearshift lever is a component mounted on the automobile's transmission, mainly used to support gear shifting. Its primary function is to switch between different gears according to driving needs, adjusting the vehicle's speed and power output. To test the quality and lifespan of an automobile gearshift lever, a testing machine is required.

[0003] A search revealed that currently available gear shift lever life testing machines suffer from complex structures, are difficult to operate, have low testing efficiency, and are prone to significant errors in test results, hindering subsequent technical research and improvement efforts. Therefore, there is an urgent need to improve existing gear shift lever life testing machines and provide a new type of gear shift lever life testing machine. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a gear shift lever life tester that is reasonably designed, simple in structure, easy to operate, and provides accurate measurement data, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gear shift lever life testing machine includes a base plate, a controller, and an infrared beam counting sensor. A test platform is fixedly mounted on the upper left of the base plate, and the controller is fixedly mounted on the upper right of the base plate. The infrared beam counting sensor is fixedly mounted on the upper right of the test platform. A sliding groove is opened inside the left end of the test platform. A limit rod is fixedly connected to the middle of the sliding groove. A T-shaped rod is slidably mounted on the outside of the limit rod. A drive assembly is provided behind the bottom end of the T-shaped rod. Vertical shafts are fixed above both the left and right ends of the T-shaped rod. Clamping and pushing-pull assemblies are slidably mounted on the outside of the vertical shafts. The infrared beam counting sensor, the drive assembly, and the clamping and pushing-pull assembly are all electrically connected to the controller through connecting wires.

[0007] In a preferred embodiment, the vertical section of the T-shaped rod is engaged and slidably located within the groove and slidably sleeved on the outside of the limiting rod, and a rectangular through groove structure is provided inside the bottom end of the vertical section of the T-shaped rod.

[0008] In a preferred embodiment, the drive assembly includes a drive motor, a disc, and a fixed column. The drive motor is fixedly installed on the upper left rear end of the base plate, and the output end of the drive motor is fixedly connected to the disc. The fixed column is fixedly installed on the outer edge of the front end face of the disc away from its center.

[0009] In a preferred embodiment, the front end of the fixed column is guided and slidably located within a rectangular through-groove structure at the bottom of the T-shaped rod, and the T-shaped rod forms a left-right reciprocating sliding structure through the fixed column.

[0010] In a preferred embodiment, the clamping push-pull assembly includes a movable plate, a movable column, a limiting groove, a bidirectional lead screw, a servo motor, and clamping rods. The left and right ends of the movable plate are slidably sleeved on the outer sides of the two vertical shafts, respectively. A movable column is mounted on a bearing in the middle of the movable plate. A limiting groove is formed in the middle of the front end of the movable column. A bidirectional lead screw is rotatably mounted in the limiting groove. A servo motor is fixedly mounted on the outer wall of the left side of the front end of the movable column. The output end of the servo motor is fixedly connected to the left end of the bidirectional lead screw. Clamping rods are threaded on the outer sides of the oppositely threaded ends of the bidirectional lead screw.

[0011] In a preferred embodiment, the two clamping rods are linked by a bidirectional lead screw, and the sliding directions of the two clamping rods are always opposite to each other. The front end of the clamping rod is provided with an arc-shaped section, and a rubber pad is adhered to the inner wall of the arc-shaped section.

[0012] In a preferred embodiment, a spring is provided on the outer side of the bottom end of the vertical shaft and below the movable plate, with the two ends of the spring fixedly connected to the T-shaped rod and the movable plate, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the solution of this utility model:

[0015] By starting the servo motor to control the rotation of the bidirectional lead screw, the two clamping rods can be controlled to slide and move closer to each other to clamp the shift lever. Then, the drive motor can be started to control the disc to rotate at a constant speed. The fixed column can squeeze and push the T-shaped rod, the vertical shaft, and the clamping push-pull assembly to slide back and forth, thereby pulling the shift lever to deflect back and forth. During the deflection of the shift lever, the movable column can be rotated, and the movable plate can be raised and lowered outside the vertical shaft for easy and stable deflection of the shift lever, simulating the shifting operation. This facilitates the testing of the lifespan of the shift lever. The device has a simple structure and is easy to operate.

[0016] During the life test, as the T-shaped rod moves back and forth to control the shift lever's reciprocating deflection, each time the shift lever is pushed to deflect, the right end of the T-shaped rod enters the infrared beam counting sensor once, thus facilitating the counting of the shift lever's deflection counts until the shift lever malfunctions. This allows for obtaining accurate shift lever life data, which is helpful for subsequent technical improvement research. Attached Figure Description

[0025] 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:

[0026] like Figure 1-5As shown, the shift lever life testing machine of this utility model includes a base plate 1, a controller 3, and an infrared beam counting sensor 4. A test platform 2 is fixedly installed on the upper left of the base plate 1, and the controller 3 is fixedly installed on the upper right of the base plate 1. The infrared beam counting sensor 4 is fixedly installed on the upper right of the test platform 2. A sliding groove 5 is opened inside the left end of the test platform 2. A limit rod 6 is fixedly connected to the middle of the sliding groove 5. A T-shaped rod 7 is slidably provided on the outside of the limit rod 6. A drive assembly 8 is provided behind the bottom end of the T-shaped rod 7. Vertical shafts 10 are fixed above both the left and right ends of the T-shaped rod 7. A clamping push-pull assembly 9 is slidably provided on the outside of the vertical shaft 10. The infrared beam counting sensor 4, the drive assembly 8, and the clamping push-pull assembly 9 are all electrically connected to the controller 3 through connecting wires.

[0027] Based on the above structure, the vertical section of the T-shaped rod 7 is engaged and slidably located within the slide groove 5 and slidably sleeved on the outside of the limiting rod 6, and a rectangular through groove structure is opened inside the bottom end of the vertical section of the T-shaped rod 7.

[0028] In this embodiment, the sliding groove 5 and the limiting rod 6 are used to improve the stability of the T-shaped rod 7 during the left and right sliding process.

[0029] Based on the above structure, the drive assembly 8 includes a drive motor 81, a disc 82 and a fixing post 83. The drive motor 81 is fixedly installed on the upper left rear end of the base plate 1. The output end of the drive motor 81 is fixedly connected to the disc 82. The fixing post 83 is fixedly installed on the outer edge of the front end face of the disc 82 away from its center.

[0030] Based on the above structure, the front end guide slide of the fixed column 83 is located in the rectangular through groove structure inside the bottom end of the T-shaped rod 7, and the T-shaped rod 7 forms a left-right reciprocating sliding structure through the fixed column 83.

[0031] In this embodiment, when the drive motor 81 is started to control the rotation of the disk 82, the T-shaped rod 7 can be pressed by the fixed column 83 eccentrically set on the front end face of the disk 82, thereby controlling the T-shaped rod 7 to slide back and forth.

[0032] Based on the above structure, the clamping push-pull assembly 9 includes a movable plate 91, a movable column 92, a limiting groove 93, a bidirectional lead screw 94, a servo motor 95, and a clamping rod 96. The left and right ends of the movable plate 91 are slidably sleeved on the outside of the two vertical shafts 10, respectively. The movable column 92 is mounted on the bearing in the middle of the movable plate 91. A limiting groove 93 is opened in the middle of the front end of the movable column 92. The bidirectional lead screw 94 is rotatably installed in the limiting groove 93. The servo motor 95 is fixedly installed on the outer wall of the left side of the front end of the movable column 92. The output end of the servo motor 95 is fixedly connected to the left end of the bidirectional lead screw 94. The clamping rod 96 is threaded on the outer side of the opposite threads at the left and right ends of the bidirectional lead screw 94.

[0033] Based on the above structure, the two clamping rods 96 are linked together by a bidirectional lead screw 94, and the sliding directions of the two clamping rods 96 are always opposite to each other. The front end of the clamping rod 96 is provided with an arc-shaped section, and a rubber pad 97 is adhered to the inner wall of the arc-shaped section.

[0034] In this embodiment, starting the servo motor 95 controls the bidirectional lead screw 94 to rotate, which in turn controls the two clamping rods 96 to slide in opposite directions, making it easier to clamp the shift lever and conduct life tests on the shift lever.

[0035] Based on the above structure, a spring 11 is provided on the outer side of the bottom end of the vertical shaft 10 and below the movable plate 91. The two ends of the spring 11 are fixedly connected to the T-shaped rod 7 and the movable plate 91, respectively.

[0036] In this embodiment, the spring 11 is used to provide support for the clamping push-pull assembly 9.

[0037] The working principle of this utility model is as follows:

[0038] When using it, first fix the gear shift lever on top of test bench 2 as follows: Figure 1 As shown in the diagram, the gear lever is positioned between the arc-shaped sections at the front ends of the two clamping rods 96. The servo motor 95 can be activated to control the rotation of the bidirectional lead screw 94, thereby controlling the two clamping rods 96 to move closer together and clamp the gear lever. Subsequently, the drive motor 81 is activated to control the disc 82 to rotate at a constant speed. The fixed column 83 can press the T-shaped rod 7, which has a rectangular through-slot structure at the bottom, and push the T-shaped rod 7, the vertical shaft 10, and the clamping push-pull assembly 9 to slide back and forth, thereby pulling the gear lever to deflect back and forth. When the gear lever deflects, the movable column 92 can rotate, and the movable plate 91 can be adjusted up and down outside the vertical shaft 10 to facilitate the stable deflection of the gear lever. By controlling the deflection of the gear lever, the shifting operation can be simulated, which is convenient for testing the service life of the shift lever. The device has a simple structure and is easy to operate.

[0039] As the T-shaped rod 7 moves back and forth to control the gear lever to deflect back and forth during the life test, each time the gear lever is pushed to deflect, the right end of the T-shaped rod 7 can enter the infrared beam counting sensor 4 once, which makes it easy to accurately count the number of deflections of the gear lever until the gear lever fails, so as to obtain accurate data on the life of the gear lever and facilitate subsequent technical improvement research.

[0040] It should be noted that this device is powered by an external power source. The controller 3, infrared beam counting sensor 4, drive motor 81 and servo motor 95 are all existing products. Their specific control methods are existing mature technologies and are not the innovative direction of this case, so they will not be described in detail.

[0041] 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.
