[0026] Please see Figure 1-3This utility model provides an embodiment of a car media player button life testing machine: A car media player button life testing machine includes a housing 1 and an upper and lower adjustment frame 2. The housing 1 includes clamping bars 101 and soft rubber pads 102. Two sets of clamping bars 101 are symmetrically arranged on both sides of the bottom end inside the housing 1. The soft rubber pads 102 are located on one side of the clamping bars 101. The soft rubber pads 102 can prevent the clamping bars 2 from squeezing the car media player, thus avoiding damage to the car media player during clamping. The upper and lower adjustment frame 2 includes a left and right adjustment frame 201, an adjustment groove 202, and an adjustment screw. 203 and locking block 204, two sets of left and right adjustment brackets 201 are located on the outside of the upper and lower adjustment brackets 2, and adjustment grooves 202 are symmetrically opened at both ends inside the left and right adjustment brackets 201. The left and right adjustment brackets 201 and the upper and lower adjustment brackets 2 can be adjusted back and forth and left and right through the adjustment grooves 202, so as to adjust the position of the rubber pressing block 206. Two sets of adjustment screws 203 are symmetrically arranged at both ends of the upper and lower adjustment brackets 2, and locking block 204 is located at one end of the adjustment screw 203 located inside the adjustment groove 202. The position of locking block 204 can be adjusted through the adjustment screw 203. The adjustment mechanism allows for locking and positioning of the left and right adjustment brackets 201. A servo motor 103 is installed at the bottom of one side of the housing 1. The output end of the servo motor 103 is connected to a bidirectional screw 104 that passes through the interior of the two sets of clamping bars 101. The servo motor 103 can drive the bidirectional screw 104 to rotate. The positive and negative threads on the outer side of the bidirectional screw 104 allow for the two sets of clamping bars 101 to be adjusted in opposite directions, enabling the clamping and fixing of different models of in-vehicle media players. Each front end of one side of the two sets of clamping bars 101 is equipped with a positioning rod 105 that passes through the outside of the housing 1, serving as a positioning element. The effect is more stable in adjusting the clamping bar 101. A cylinder 205 is provided at the middle position of the top of the left and right adjustment frame 201. A rubber pressing block 206 is provided at the telescopic end of the cylinder 205. The rubber pressing block 206 can be adjusted up and down by the cylinder 205. The buttons of the car media player can be pressed continuously for testing. A hydraulic cylinder 3 is provided at the middle position of both sides of the top of the box 1. A positioning rod 301 is provided at the four corners of the top of the upper and lower adjustment frame 2, which extends to the top of the box 1. The upper and lower adjustment frame 2 can be stably adjusted up and down by the hydraulic cylinder 3 and the positioning rod 301.
[0027] Please refer to this carefully. Figure 1 and Figure 2The soft rubber pad 102 is fixedly connected to the clamping strip 101 by adhesive, providing a protective effect and better clamping protection for the vehicle media player. The left and right adjustment bracket 201 is movably connected to the upper and lower adjustment bracket 2 via the adjustment groove 202, allowing the left and right adjustment bracket 201 to be adjusted forward, backward, left, and right. A slot is provided in the middle of the interior of the upper and lower adjustment bracket 2. One end of the locking block 204 is equipped with a bearing, and one end of the adjusting screw 203 passes through the bearing. The bearing allows the locking block 204 and the adjusting screw 203 to rotate, facilitating left and right adjustments. The position of the adjustment bracket 201 is limited. The end of the adjustment screw 203 away from the locking block 204 is equipped with a manual rotating block, which can be manually rotated. Both ends of the left and right adjustment brackets 201 are equipped with threaded holes that match the adjustment screw 203, which can achieve the effect of limiting adjustment. The locking block 204 can be adjusted back and forth by adjusting the screw 203. The end of the locking block 204 away from the adjustment screw 203 is equipped with an anti-slip pad, which makes the positioning between the left and right adjustment brackets 201 and the upper and lower adjustment brackets 2 more stable. A display control panel is provided on one side of the housing 1.
[0028] Please refer to this carefully. Figure 1 and Figure 3 The servo motor 103 is connected to the housing 1 by bolts, allowing the servo motor 103 to be installed on one side of the housing 1. The rear ends of both sets of clamping bars 101 are provided with threaded holes that match the bidirectional screws 104, which serve as limit adjustment. The two sets of clamping bars 101 can be adjusted left and right, and can clamp and fix different models of car media players. The bottom of both sides of the housing 1 are provided with positioning holes 1, and positioning rod 105 passes through the interior of the positioning holes 1, which serves as a limit and makes the adjustment of the two sets of clamping bars 101 more stable. The telescopic ends of the two sets of hydraulic cylinders 3 are connected to the top of the upper and lower adjustment frame 2. The upper and lower adjustment frame 2 can be adjusted up and down through the hydraulic cylinders 3. The four corners of the top of the housing 1 are provided with positioning holes 2, and positioning rod 201 passes through the interior of the positioning holes 2, which makes the adjustment of the upper and lower adjustment frame 2 more stable.
[0029] Example 2:
[0030] This embodiment, based on the previous embodiment, further expands the intelligence and comprehensiveness of the in-vehicle media player button life tester, aiming to more realistically simulate user button pressing behavior and improve testing efficiency and fault diagnosis capabilities. The tester in this embodiment maintains the same basic structure as the first embodiment. Based on this, the following innovative improvements have been added:
[0031] A high-precision miniature force sensor is integrated into the bottom of the existing rubber pressing block 206. This sensor is connected to the central control module via wires to provide real-time feedback on the pressing force. The central control module controls the thrust of the cylinder 205 in a closed loop according to a preset pressing force curve, achieving precise application and maintenance of the pressing force. Simultaneously, the pressing trajectory driven by the cylinder 205 can be extended into a miniature three-axis motion platform driven by a miniature servo motor, enabling fine-tuning of the button in the XY direction and pressing in the Z direction. This simulates the trajectory of a user pressing the button from different angles and directions, improving the realism of the test.
[0032] Working Principle: In use, the vehicle media player is placed in the middle between the two sets of clamping bars 101. The servo motor 103 drives the bidirectional screw 104 to rotate. The bidirectional screw 104 engages with the threaded holes inside the two sets of clamping bars 101, allowing for relative adjustment of the two sets of clamping bars 101. The positioning rod 105 further stabilizes the adjustment of the two sets of clamping bars 101, enabling clamping and fixing of different models of vehicle media players. The latex pad 102 protects the vehicle media player. Manually rotating the adjusting screw 203 moves the locking block 204 to both ends inside the adjusting groove 202. The adjusting groove 202 allows for adjustment of the left and right adjustment brackets 20... Adjust the upper and lower adjustment frame 2 back and forth and left and right to align the rubber pressing block 206 with the button position of the car media player. Then adjust the adjusting screw 203 until the locking block at one end of the adjusting screw 203 is in contact with the upper and lower adjustment frame 2. This allows for adjustment of the test pressing position, facilitating the testing of the button life of different models of car media players. The upper and lower adjustment frame 2 is adjusted downwards by the hydraulic cylinder 3 and the positioning rod 201 until the bottom of the rubber pressing block 206 is aligned with the top of the button. The cylinder 205 drives the rubber pressing block 206 to continuously press the button of the car media player and test its life, thus improving the practicality of the button life testing machine.
