Description

Technical Field

[0001] This patent relates to the field of waterproof testing technology, specifically a waterproof testing device for automotive steering wheel buttons. Background Technology

[0002] After the automotive steering wheel is manufactured and assembled, a waterproof sealing test is required for the button positions. Since the buttons on the steering wheel are pressed, water can inevitably seep into the steering wheel. The existing testing method involves attaching a cover to the steering wheel with the button position inside the cover, then adding water. If the water level drops quickly, the button position is not waterproof; if the water level drops slowly, the waterproofing is stronger. However, if the button position is tightly fitted to the button groove, it can cause jamming when pressed, affecting usability. If the cover obstructs the button position, it's difficult to test the state after the button is pressed. If the seal is poor, the seal deteriorates after the button is pressed. Therefore, we propose a waterproof testing device for automotive steering wheel buttons. Utility Model Content

[0003] The purpose of this patent is to provide a waterproof testing device for automotive steering wheel buttons to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this patent provides the following technical solution: a waterproof testing device for automotive steering wheel buttons, comprising a placement seat and a horizontal plate. A vertical plate is integrally formed on the right end of the placement seat. A lead screw motor is fixedly installed on the right side of the vertical plate.

Detailed Implementation

[0017] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] Please see Figure 1 , Figure 2 and Figure 3 This patent provides a technical solution: a waterproof testing device for automotive steering wheel buttons, including a placement seat 1 and a horizontal plate 4. The right end of the placement seat 1 is integrally formed with a vertical plate 2. A lead screw motor 3 is fixedly installed on the right side of the vertical plate 2. A screw is fixedly installed on the left end of the shaft of the lead screw motor 3. A threaded groove is provided in the middle of the right end of the horizontal plate 4. The inner side wall of the threaded groove is screwed to the side wall of the screw. A limiting mechanism is provided at the top of the horizontal plate 4. An electric push rod 5 is fixedly installed at the bottom of the horizontal plate 4. A connecting plate is fixedly installed at the bottom end of the piston rod of the electric push rod 5. A water cylinder 6 is fixedly installed at the left end of the connecting plate. A cover 7 is fixedly installed at the bottom end of the water cylinder 6. A water filling hopper 8 is embedded in the left side wall of the water cylinder 6. A sliding hole is provided at the top of the water cylinder 6.

[0019] The bottom shape of the cover 7 matches the position of the button on the steering wheel to be tested. The bottom of the cover 7 is also equipped with a sealing ring to increase the sealing effect after the cover 7 is fastened to the steering wheel and prevent water leakage.

[0020] A slide rod 9 is slidably installed on the inner side wall of the slide hole. A pressing plate 10 is fixedly installed on the top of the slide rod 9. A spring 11 is sleeved on the side wall of the slide rod 9. The upper and lower ends of the spring 11 are fixedly installed on the bottom of the pressing plate 10 and the top of the water cylinder 6, respectively. The spring 11 is in the normal state.

[0021] The button plate 10 has a mounting hole 12 in the middle, and a connecting rod 13 is fixedly installed on the inner side wall of the mounting hole 12. The water cylinder 6 has a linkage plate 14 on the upper side, and a sleeve hole 15 is provided on the linkage plate 14. The sleeve hole 15 is fitted onto the connecting rod 13, and the bottom of the linkage plate 14 is attached to the top of the button plate 10.

[0022] If you need to press a single button, you can simply press down the corresponding link 13. If you need to press all the buttons in the same area at the same time, you can press down the linkage plate 14, which will cause the slide bar 9 to move downwards simultaneously.

[0023] Specifically, the top of the placement base 1 is provided with a circular groove 16.

[0024] The circular groove 16 is designed to define the installation position of the steering wheel.

[0025] Specifically, the left side wall of the water cylinder 6 is provided with an air hole 17.

[0026] When water is poured into the water cylinder 6, the internal air can flow out through the air hole 17.

[0027] Specifically, the left side wall of the water tank 6 is provided with graduation lines.

[0028] The scale markings make it easy to observe changes in the water level inside the water tank 6.

[0029] Specifically, the limiting mechanism includes a fixed plate 18, the right end of which is fixedly installed on the top left side of the upright plate 2. The bottom front and rear sides of the fixed plate 18 are provided with wheel grooves 19. The top right front and rear ends of the horizontal plate 4 are connected to limiting wheels 20 through wheel seats. The front and rear contours inside the wheel grooves 19 match the contours at the wheel body edges of the limiting wheels 20. The top ends of the two limiting wheels 20 are respectively rolled and installed in the two wheel grooves 19.

[0030] In traditional lead screw systems, the limiting mechanism mostly uses a slider that slides in a groove on a slide rail, which is a sliding limiting mechanism. This results in significant friction and wear between components. However, by using a limiting wheel 20 that rolls and hangs in a wheel groove 19, it becomes a rolling limiting mechanism, which can greatly reduce friction and wear.

[0031] Specifically, both ends of the wheel groove 19 are open.

[0032] Since both ends of the wheel groove 19 are open, it is convenient to install the limit wheel 20 in the wheel groove 19.

[0033] Working principle: The electric actuator 5 moves the water cylinder 6 downwards, and the cap 7 closes and seals it on the steering wheel. Water is then added to the water cylinder 6 through the water inlet 8. The water volume can be 20 ml at the mark. Observe the water level change. When you need to press a button, you can directly press the corresponding connecting rod 13 downwards. The sliding rod 9 moves downwards and you can press the button to observe the water level change. If you need to press all the buttons in the same area at the same time, you can press the linkage plate 14 downwards. The linkage plate 14 moves the sliding rod 9 downwards at the same time. Press multiple buttons at the same time and observe the water level change.

[0034] After the button area on the right is tested, the horizontal plate 4 can be moved to the left by the lead screw motor 3, so that the water tank 6 can be moved to the upper side of the button area on the left, and then the test can be performed.
