Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of durability testing of automobile parts, in particular to a wear and tear durability device for a combination switch lock tongue. Background Art
[0002] Under the current technological background, durability testing of automotive combination switches faces an efficiency bottleneck, mainly due to the complexity of the test equipment and cumbersome operation. According to Section 4.17 of the industry standard QC / T 218-2017 "Technical Requirements for Combination Switches on Steering Columns for Automobiles", durability is one of the key indicators for measuring the quality of combination switches, requiring them to maintain good functional status after repeated use over a long period of time. Traditional testing methods usually rely on the coordinated operation of multiple actuators to simulate the complex operation sequences in actual use. Not only is the equipment cost high, but the limited frequency of operation also makes the entire test cycle very long. Therefore, it has become necessary to develop an innovative combination switch lock tongue wear durability device.
[0003] Currently, most of the existing combination switch lock tongue wear durability devices are equipped with a large number of actuators, which leads to slow action and prolonged test cycle, reducing test efficiency. The complexity and number of test equipment are high, the cost is high and maintenance is cumbersome, and the operation process is complicated, which is not conducive to efficient and accurate evaluation of lock tongue wear durability. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a wear-resistant device for a combination switch lock tongue.
[0005] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solution: a combination switch lock tongue wear resistance device, including a mounting frame and a support frame, a first cylinder is provided on the surface of the mounting frame, a movable frame is provided at the end of the first cylinder, a second cylinder and a third cylinder are respectively provided on both sides of the movable frame, a toggle block is provided at the end of the second cylinder and the third cylinder, a switch structure is provided on the surface of the support frame, and a handle is provided on the surface of the switch structure.
[0006] Preferably, a mounting platform is provided on the surface of the mounting frame, and the first cylinder is arranged on the surface of the mounting platform.
[0007] Preferably, the movable frame is U-shaped, and the second cylinder is arranged on the top of the third cylinder.
[0008] Preferably, the front horizontal center line of the handle coincides with the front horizontal center line of the movable frame, and the position of the handle corresponds to the toggle block.
[0009] Preferably, a buffer pad is provided on the surface of the toggle block, and the toggle block and the buffer pad are arranged in two groups in an axially symmetrical manner.
[0010] Preferably, a steering wheel is provided on the surface of the switch structure, and the steering wheel and the handle are connected through a combination switch transmission.
[0011] Preferably, the surfaces of the second cylinder and the third cylinder are provided with fixing plates, and the surfaces of the fixing plates are provided with fixing bolts.
[0012] Beneficial Effects
[0013] The utility model utilizes a first cylinder, a movable frame, a second cylinder, a third cylinder, and a toggle block. When the first cylinder extends upward, it drives the movable frame upward, thereby driving the bottom toggle block upward, effectively toggling the handle and causing the lock tongue in the switch structure to pop out smoothly, thereby fixing the handle position. Subsequently, the first cylinder retracts downward to restore its original position, and the movable frame descends accordingly. At this time, the second cylinder simultaneously extends downward, pushing the top toggle block downward, resetting the handle, and the lock tongue automatically returns to its initial position. Using a similar principle, when the first cylinder extends downward, the top toggle block can be used to toggle the handle downward. Subsequently, the first cylinder returns to its original position upward, and the bottom toggle block is responsible for returning the handle to its original position. The entire endurance operation can be completed in a prescribed sequence through a simple actuator. This series of actions is simple and efficient, ensuring the accuracy and reliability of the test, significantly simplifying the test process, significantly shortening the test time, and accelerating the product verification process. It not only saves valuable R&D cycles and resources for enterprises, but also reduces the complexity and number of test equipment, thereby effectively reducing costs and maintenance complexity, and improving overall test efficiency and user experience.

However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0021] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:

The surface of the mounting frame 1 is provided with a first cylinder 5, and the piston movement of the first cylinder 5 is used to achieve precise control of the movable frame 6, thereby driving the second cylinder 7 and the third cylinder 9 to perform subsequent test actions, a movable frame 6 is provided at the end of the first cylinder 5, and the second cylinder 7 and the third cylinder 9 are respectively provided on both sides of the movable frame 6, and the shape of the movable frame 6 is U-shaped. Through the structural design and position layout of the movable frame 6, it is ensured that the second cylinder 7 and the third cylinder 9 can accurately and synchronously control the switch structure 3 is tested, the second cylinder 7 is set on the top of the third cylinder 9, and the second cylinder 7 and the third cylinder 9 are extended and retracted to simulate the operating force and frequency in actual use, and the wear durability test of the lock tongue part of the switch structure 3 is carried out. The second cylinder 7 and the third cylinder 9 are provided with a fixing plate 13 on the surface of the second cylinder 7 and the third cylinder 9, and the surface of the fixing plate 13 is provided with a fixing bolt 14. The fixing plate 13 and the fixing bolt 14 are used to fix the positions of the second cylinder 7 and the third cylinder 9 on the movable frame 6. The ends of the second cylinder 7 and the third cylinder 9 are provided with a toggle block 10, which is used to directly contact and operate the handle 8 part of the switch structure 3. The surface of the toggle block 10 is provided with a buffer pad 11, which is used to reduce the impact force when the toggle block 10 contacts the handle 8 part, and the toggle block 10 and the buffer pad 11 are provided in two groups axially symmetrically.
[0024] A switch structure 3 is provided on the surface of the support frame 2. The switch structure 3, as the object to be measured, includes key components such as a lock tongue and a handle 8. The switch structure 3 is composed of a moving contact, a static contact, a rotating shaft, a handle 8, a positioning mechanism and a shell. The lock tongue, as part of the positioning mechanism, is connected to the handle 8 through a specific mechanical structure. When the handle 8 is rotated to a certain position, the moving contact is driven by the rotating shaft to contact the corresponding static contact, thereby realizing the on-off of the circuit. At the same time, the positioning mechanism (including the lock tongue) will lock or unlock according to the position of the handle 8. The pop-up or return of the lock tongue is usually driven by a spring or other mechanical force to ensure the stability of the handle 8 in the selected position. The structure includes mechanical elements such as gears, connecting rods, and cams, which work together to realize the transmission from the handle 8 to the lock tongue. For example, when the handle 8 is rotated, the cam is driven to rotate through the connecting rod, thereby pushing the lock tongue to pop out or return. A steering wheel 12 is provided on the surface of the switch structure 3, and the steering wheel 12 and the handle 8 are connected through the switch structure 3. The rotation of the steering wheel 12 triggers the corresponding action of the switch structure 3, thereby realizing the wear durability test of the lock tongue part. A handle 8 is provided on the surface of the switch structure 3, and the front horizontal center line of the handle 8 coincides with the front horizontal center line of the movable frame 6, and the position of the handle 8 corresponds to the toggle block 10, which is convenient for toggling the handle 8.
[0025] When the first cylinder 5 extends upward, it drives the movable frame 6 to rise, and then drives the bottom toggle block 10 to move upward, effectively toggling the handle 8, and driving the lock tongue to pop out smoothly through the transmission structure (such as gears, connecting rods, cams, etc.), thereby fixing the position of the handle 8. Subsequently, the first cylinder 5 contracts downward to restore its original shape, and the movable frame 6 drops accordingly. At this time, the second cylinder 7 extends downward synchronously, pushing the top toggle block 10 to move downward, resetting the handle 8, and the lock tongue automatically returns to its initial position. Through a similar principle, when the first cylinder 5 extends downward, the top toggle block 10 can be used to toggle the handle 8 downward, and then the first cylinder 5 returns to its original position upward, and the bottom toggle block 10 is automatically returned to its initial position. The moving block 10 is responsible for restoring the handle 8 to its original position, setting the test number and frequency according to the test requirements, so that the second cylinder 7 and the third cylinder 9 repeatedly perform telescopic movements, thereby conducting a long-term wear durability test on the handle 8 and the lock tongue part. The entire durability action can be completed in the prescribed action sequence through a simple actuator. This series of actions is concise and efficient, ensuring the accuracy and reliability of the test, significantly simplifying the test process, greatly shortening the test time, and accelerating the process of product verification. It not only saves valuable R&D cycles and resources for enterprises, but also reduces the complexity and quantity of test equipment, thereby effectively reducing costs and the tediousness of maintenance. Specific embodiment two:
[0027] Reference Figure 4On the premise of meeting the above structure, the second cylinder 7, the third cylinder 9 and the toggle block 10 can be disassembled, and a servo motor can be set at the steering wheel 12. By toggling the handle 8, the lock tongue in the switch structure 3 pops out. The steering wheel 12 is driven by the servo motor to rotate forward, the lock tongue is pressed and automatically returns to its position, the handle 8 automatically returns to its position, and the handle 8 is toggled in the reverse direction. The combination switch lock tongue pops out, the steering wheel 12 is reversed, and returns to its initial position, and the lock tongue automatically returns to its position, thereby completing the wear durability test of the combination switch lock tongue simply and quickly.
[0028] In summary:
[0029] 1. The first cylinder 5, the movable frame 6, the second cylinder 7, the third cylinder 9 and the toggle block 10 are used to realize that when the first cylinder 5 extends upward, the movable frame 6 is driven to rise, and then the bottom toggle block 10 is driven to move upward, effectively toggling the handle 8, so that the lock tongue in the switch structure 3 is smoothly ejected, thereby fixing the position of the handle 8. Subsequently, the first cylinder 5 contracts downward to restore the original state, and the movable frame 6 falls accordingly. At this time, the second cylinder 7 extends downward synchronously, pushing the top toggle block 10 to move downward, resetting the handle 8, and the lock tongue automatically returns to its initial position. Through a similar principle, when the first cylinder 5 extends downward, it can effectively Use the top toggle block 10 to push the handle 8 downward, and then the first cylinder 5 returns to its original position upward. The bottom toggle block 10 is responsible for restoring the handle 8 to its original position. The entire endurance action can be completed in the prescribed sequence through a simple actuator.
