Description

Technical Field

[0001] The utility model relates to the technical field of durability testing of automotive switches, and particularly to a durability testing device for automotive switches. Background Technique

[0002] The durability testing of automotive switches is a crucial step to ensure that various switches inside the vehicle can work reliably for a long time. The switch is repeatedly operated a certain number of times through a dedicated testing device to simulate its operation frequency during the vehicle's service life. Usually, an expected service life is set, such as 100,000 times or more.

[0003] The rotary light switch is used to control the switches of the vehicle's front fog lights, rear fog lights, automatic lamp tubes, small lights, and headlights. It plays a crucial role during the vehicle's use. However, during the durability testing process, due to the special structure of the rotary light switch, it is rather troublesome to disassemble and assemble, which is not convenient for quickly conducting the test and reduces the test efficiency.

A detection mechanism 2 is installed at the top of the machine table 1. An adjustment mechanism 3 is arranged on one side of the machine table 1 opposite to the detection mechanism 2. A bearing mechanism 4 is connected to the adjustment mechanism 3. A lighting switch 5 is fixed on the bearing mechanism 4. And a fixing mechanism 6 is arranged outside the lighting switch 5. The fixing mechanism 6 includes a groove 601 opened on the bearing mechanism 4. The groove 601 is used to carry a slide bar 602 and a fastening spring 603. The slide bar 602 is slidably connected in the groove 601. The slide bar 602 is used to guide the movement of a pressing plate 604. A fastening spring 603 is arranged outside the slide bar 602. The reaction force of the fastening spring 603 can reset the pressing plate 604 and the slide bar 602. One ends of the fastening spring 603 and the slide bar 602 are both fixed with the pressing plate 604. The pressing plate 604 can fasten the lighting switch 5, which is convenient for the staff to disassemble and assemble the lighting switch 5. The pressing plate 604 abuts against the frame of the lighting switch 5.

[0022] As Figures 1 - 2 shown in the figure, the detection mechanism 2 includes a chassis 201 with an L-shaped structure. A stepping motor 202 is fixed on the chassis 201, which is convenient to support the stepping motor 202 through the chassis 201.

[0023] As Figures 1 - 2 shown in the figure, a support shaft 203 is installed at the output end of the stepping motor 202. A test frame 204 is fixed at one end of the support shaft 203. And the test frame 204 and the lighting switch 5 are on the same horizontal plane. It can make the stepping motor 202 drive the test frame 204 to rotate through the support shaft 203. When the test frame 204 contacts the lighting switch 5, it can drive the knob inside it to rotate, thereby realizing the test of the lighting switch 5.

[0024] As Figures 1 - 2 shown in the figure, the adjustment mechanism 3 includes a support plate 301 fixed on the machine table 1. A rotating motor 302 is installed on one side of the support plate 301. An adjustment lead screw 303 is installed at the output end of the rotating motor 302, which is convenient to drive the adjustment lead screw 303 to rotate through the rotating motor 302 on the support plate 301.

[0025] As Figures 1 - 2 shown in the figure, guide rods 304 are symmetrically arranged on both sides of the adjustment lead screw 303. And a chute 305 is arranged between the chassis 201 and the support plate 301, which can be guided through the guide rods 304 and the chute 305.

[0026] As Figures 1 - 3As shown in the figure, the bearing mechanism 4 includes a sliding seat 401 and a mounting plate 402. The sliding seat 401 is slidably connected to the guide rod 304, and the sliding seat 401 is threadedly connected to the adjusting lead screw 303. The light switch 5 is fixed on the mounting plate 402, which facilitates fixing the light switch 5 on the mounting plate 402. Then, the adjusting lead screw 303 drives the sliding seat 401 to move horizontally along the guide rod 304 and the chute 305, thereby driving the light switch 5 to move horizontally.

[0027] As Figures 1 - 3 As shown in the figure, a tester 7 is installed on the back of the mounting plate 402 corresponding to the light switch 5, and the tester 7 is connected to an operation panel 9 through a connecting wire 8, which can test the light switch 5 through the tester 7, and the test result is sent to the operation panel 9 through the connecting wire 8.

[0028] Working principle of this device: When this device is specifically used and the light switch 5 is being tested, the staff member pulls the pressing plate 604, causing the pressing plate 604 to drive the sliding rod 602 to move within the groove 601. The pressing plate 604 moves away from the mounting plate 402. The staff member inserts the power switch into the mounting plate 402 and connects it to the tester 7. After insertion is completed, the pressing plate 604 is released. The pressing plate 604 and the sliding rod 602 are reset by the reaction force of the fastening spring 603, and the light switch 5 is fastened through the pressing plate 604, facilitating the disassembly and assembly of the light switch 5 by the staff member. After installation is completed, the rotating motor 302 on the support plate 301 drives the adjusting lead screw 303 to rotate. The adjusting lead screw 303 can drive the sliding seat 401 to move horizontally along the guide rod 304 and the chute 305, thereby adjusting the position of the light switch 5 until the knob on the light switch 5 enters the test rack 204. After adjustment is completed, the stepping motor 202 on one side of the bottom frame 201 drives the test rack 204 to rotate through the support shaft 203. The rotation of the test rack 204 drives the knob on the light switch 5 to rotate, and the light switch 5 is tested through the tester 7. The test result is sent to the operation panel 9 through the connecting wire 8, and during the test process, the pressing plate 604 can prevent the light switch 5 from rotating and displacing.

[0029] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, all belong to the protection scope of the present utility model.
