Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing, and in particular to a roller durability testing device. Background Technology

[0002] During automobile assembly, various components undergo performance testing to ensure vehicle performance and driving safety. The in-car multimedia system is an essential module, and the scroll wheel adjuster is a common component. On some models, the steering wheel scroll wheel is used for adjusting music volume, muting / resume playback, and other multimedia operations, or to support switching of driver assistance functions. The in-car scroll wheel controller is small in size. In actual use, adjustment is achieved by rubbing the scroll wheel with your finger. However, the scroll wheel controller needs to undergo lifespan testing, which focuses on simulating finger friction to rotate the scroll wheel and thus test its durability. Currently, there is a lack of efficient and controllable durability testing devices for such small scroll wheels. Summary of the Invention

[0003] This invention proposes a roller durability testing device to solve the problem of durability testing of small rollers in automotive roller controllers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A roller durability testing device includes a base bracket, and a power switch module, a display module, a drive module, a simulated test wheel, and a fixed bracket mounted on the base bracket. The power switch module is connected to the display module and the drive module, and is used to control the power supply to the display module and the drive module, as well as the rotation speed and direction of the drive module. The display module is connected to the drive module and is used to display information about the drive module. The drive module is connected to the simulated test wheel and is used to drive the simulated test wheel to rotate around its own axis. The outer peripheral edge of the simulated test wheel is used to abut against the roller to be tested during testing and drive the roller to roll. The fixed bracket is mounted next to the simulated test wheel and is used to fix the roller controller to be tested. The outer peripheral part of the roller on the fixed roller controller abuts against the outer peripheral part of the simulated test wheel and rotates with the rotation of the simulated test wheel.

[0005] In one possible implementation, the power switch module includes a forward / stop / reverse switch and a speed switch. The forward / stop / reverse switch has three control states: forward, stop, and reverse, which are used to control the on / off state and direction of the drive module. The speed switch is used to control the speed of the drive module.

[0006] In one possible implementation, the forward / stop / reverse switch is a three-position push-button switch, wherein the three-position push-button switch consists of a forward rotation button, a stop button, and a reverse rotation button in sequence.

[0007] In one possible implementation, the speed switch is a rotary switch, which controls the speed of the drive module to increase when rotated clockwise.

[0008] In one possible implementation, the power switch module is connected to an external power source or powered by a battery.

[0009] In one possible implementation, the drive module includes a motor mount and a geared motor, with the motor mount fixedly mounted on the base bracket and the geared motor fixedly mounted on the motor mount.

[0010] In one possible implementation, the output shaft of the geared motor is coaxially mounted on a fixed disk, and the simulation test wheel is coaxially mounted on the fixed disk and rotates synchronously with the output shaft of the geared motor.

[0011] In one possible implementation, the outer periphery of the simulation test wheel is a circular structure made of a material with a high coefficient of friction.

[0012] In one possible implementation, the number of fixed brackets is at least one and they are detachably mounted on the base bracket.

[0013] In one possible implementation, the roller controller to be tested is detachably mounted on the fixed bracket.

[0014] Compared with existing technologies, the advantages of this invention are as follows: a small roller controller can be directly mounted on a fixed bracket. Activating the drive module directly drives the simulated test wheel to rotate, thus rotating the roller and simulating the situation of manually rotating the roller during actual use. The rotation speed, pressure value on the roller, and number of tests can be set independently. The testing process is precise and controllable, and the test results are accurate. Furthermore, the testing device of this invention has a small overall size, a simple testing method, and can simultaneously test multiple roller controllers with the same test parameters.

[0020] The roller controller 7 under test is small in size, and its roller 71 is generally located inside the housing of the roller controller 7, with the other half protruding from the roller controller 7. In actual use, it is necessary to apply force to the exposed part of the roller 71 with a finger and turn the roller 71 to make it roll and complete the adjustment action. The roller 71 under test is also small in size, and there are clear testing standards for the durability of the roller 71. Therefore, the present invention aims to develop a device suitable for small-sized, lightweight rollers that facilitates quick and accurate testing of roller durability.

[0021] Please refer to Figure 1A roller durability testing device includes a base bracket 1, and a power switch module 2, a display module 3, a drive module 4, a simulated test wheel 5, and a fixed bracket 6 mounted on the base bracket 1. The power switch module 2 is connected to the display module 3 and the drive module 4, and is used to control the power supply to the display module 3 and the drive module 4, as well as the rotation speed and direction of the drive module 4. The display module 3 is connected to the drive module 4 and is used to display information from the drive module 4. The drive module 4 is connected to the simulated test wheel 5 and is used to drive the simulated test wheel 5 to rotate around its own axis. The outer peripheral edge of the simulated test wheel 5 is used to abut against the roller 71 to be tested during testing and drive the roller 71 to roll. The fixed bracket 6 is mounted next to the simulated test wheel 5 and is used to fix the roller controller 7 to be tested. The outer peripheral part of the roller on the fixed roller controller 7 abuts against the outer peripheral part of the simulated test wheel 5 and rotates with the rotation of the simulated test wheel 5.

[0022] The usage process of the roller durability device of this utility model is as follows: The roller controller 7 to be tested is fixedly installed on the fixed bracket 6, and the roller 71 of the roller controller 7 is exactly abutted against the outer peripheral side of the simulated test wheel 5, and the axis of the roller 71 is parallel to the axis of the simulated test wheel 5. The drive module 4 and the rotation direction and speed of the simulated test wheel 5 are set in the power switch module 2. The switch is turned on to power on the device, and the simulated test wheel 5 rotates according to the set program, driving the roller 71 to rotate, simulating the situation of a person rolling the roller 71 by hand in actual use. The display module 3 displays the rotation information of the drive module 4 and the simulated test wheel 5 in real time, such as the number of rotations. Every 50,000 rotations, the appearance of the roller is checked for any abnormalities, and the test results are recorded. After 150,000 tests, if the sample structure is found to be normal, the roller quality is qualified; otherwise, the roller quality is unqualified.

[0023] Preferably, in actual use, the test rate can be set to 3 seconds / revolution, the test force value to 200gf, and the number of tests to 300,000, including 150,000 forward rotations and 150,000 reverse rotations. During the forward rotation test, the appearance and structure of the sample roller 71 are checked for abnormalities every 50,000, 100,000, and 150,000 times, and the test results are recorded. During the reverse rotation test, the appearance and structure of the sample roller 71 are checked for abnormalities every 50,000, 100,000, and 150,000 times, and the test results are recorded.

[0024] In some embodiments, the power switch module 2 includes a forward / stop / reverse switch 21 and a speed switch 22. The forward / stop / reverse switch 21 has three control states: forward, stop, and reverse, and is used to control the on / off state and direction of the drive module 4. The speed switch 22 is used to control the speed of the drive module. Testing personnel can achieve precise rotation simulation of the roller 71 simply by operating the switches. The operation is simple, has a low barrier to entry, and is easy to use and promote.

[0025] In some embodiments, the forward / stop / reverse switch 21 is a three-position push-button switch, which consists of a forward rotation button, a stop button, and a reverse rotation button. This three-position push-button switch provides clear indication and is easy to operate, effectively reducing the occurrence of misoperation. Furthermore, the forward and reverse rotation of the simulation test wheel 5 can be easily confirmed visually.

[0026] In some embodiments, the speed switch 22 is a rotary switch, and rotating the rotary switch clockwise controls the speed of the drive module 4 to increase; the operator can quickly adjust the speed by rotating the rotary switch.

[0027] In some embodiments, the power switch module 2 is connected to an external power source or powered by a battery. When powered by a battery, the device itself is not limited by the testing site and is used more flexibly.

[0028] In some embodiments, the drive module 4 includes a motor mount 41 and a geared motor 42. The motor mount 41 is fixedly mounted on the base bracket 1, and the geared motor 42 is fixedly mounted on the motor mount 41. The geared motor 42 can directly adjust the speed and direction of the motor according to the command, accurately execute the test parameters, and has greater torque, enabling it to drive the simulated test wheel 5 to rotate. When there is slight mutual compression between the simulated test wheel 5 and the roller 71 to be tested, it can drive the roller 71 to rotate synchronously.

[0029] In a further embodiment, a fixed disk 43 is coaxially mounted on the output shaft of the geared motor 42, and the simulated test wheel 5 is coaxially mounted on the fixed disk 43 and rotates synchronously with the output shaft of the geared motor 42. The fixed disk 43 between the simulated test wheel 5 and the geared motor 42 increases the fixed area of ​​the simulated test wheel 5, facilitating its installation, and also prevents the simulated test wheel 5 from shaking during rotation, enhancing its stability and thus improving the stability and accuracy of the simulated rolling test results.

[0030] In some embodiments, the outer periphery of the simulation test wheel 5 is a circular structure made of a material with a high coefficient of friction, such as rubber or silicone. During actual simulation testing, the roller 71 of the roller controller 7 under test abuts against the outer periphery of the simulation test wheel 5. The outer periphery of the simulation test wheel 5 is slightly elastic, and the roller sinks slightly into the simulation test wheel 5 to increase friction. When the outer periphery of the simulation test wheel 5 rotates, the greater friction drives the roller 71 to rotate together, simulating the situation where a person applies force to rotate the roller 71 during actual use.

[0031] In some embodiments, the number of fixed brackets 6 is at least one and is detachably mounted on the base bracket 1; further, the roller controller 7 to be tested is detachably mounted on the fixed bracket 6. The overall structure and shape of the fixed bracket 6 can be designed according to the roller controller 7, so that after the roller controller 7 is installed and fixed, the roller 71 just abuts against the periphery of the simulation test wheel 5 and is on the same plane. The detachable structure of the fixed bracket 6 can be achieved by screw fixing, magnetic fixing, adhesive fixing or other convenient and quick fixing methods. Similarly, the roller controller 7 can be detachably fixed to the corresponding fixed bracket 6 by means of buckles, magnetic attraction, strap binding or other methods.

[0032] In some embodiments, an alarm module is also included. When the device malfunctions, such as power failure, short circuit, or click failure, the alarm module will issue an alarm, which may be an audible and visual alarm. An indicator light may be set on the display module 3.

[0033] In summary, the roller durability testing device protected by this utility model has a relatively low manufacturing cost, is small in size and can be flexibly adapted to the site for testing. It is used to simulate the situation of a person turning the roller by hand in actual use, and the rotation speed, the pressure value of the roller and the number of tests can be set by the user. The testing method is simple, the detection process is precise and controllable, the detection results are accurate, and multiple roller controllers can be tested simultaneously with the same test parameters.

[0034] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
