Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a toggle switch for a car seat. Background Art

[0002] In the process of automobile manufacturing and assembly, the installation accuracy of seat toggle switches has always been a topic worthy of detailed discussion. Due to the lack of precision and relatively low installation standards that may be encountered during the installation process, there is often a small gap between the top of the toggle switch handle and its corresponding contact surface. Although this phenomenon seems subtle, it may cause a series of problems that cannot be ignored in the actual operation of the car. The most direct impact is the problem of abnormal noise during driving. The abnormal noise caused by the gap will not only interfere with the driver's concentration, but also affect consumers' affirmation of the quality of the car. In order to solve this problem, automobile manufacturers have to work hard to improve the installation accuracy and installation environment, which greatly increases the cost, but the effect achieved may not be completely proportional to the cost invested. Summary of the invention

[0003] The purpose of the utility model is to overcome the defect of abnormal noise caused by the gap in the prior art, and the utility model provides a toggle switch for a car seat.

[0004] The technical solution of the utility model comprises a dial handle, a blind hole is formed on the top surface of the dial handle, a spring button is arranged in the blind hole, the spring button is elastically and movably installed in the blind hole and the top of the spring button protrudes upward from the top surface of the dial handle, the spring button has a guide edge, and the guide edge and the hole wall of the blind hole abut against each other when the spring button is at the upper limit of the movement limit.

[0005] By adopting the above technical solution, a spring button is arranged on the top of the dial handle, and the elasticity of the spring button is used to fill the gap between the top of the dial handle and its corresponding contact surface, so that the spring button is always pre-pressed on the corresponding contact surface, and absorbs and buffers the mechanical impact that may be caused by the gap, thereby greatly reducing or even eliminating abnormal noise during operation, improving the quietness of the vehicle interior environment, and from the perspective of its structural cost, the structural design is simple, there is no need to change the installation environment in the vehicle, and the cost is effectively reduced; the guide limit of the guide edge and the blind hole wall ensures the stability of the movement trajectory of the spring button, prevents the spring button from detaching from the dial handle due to excessive gap, and improves the stability of the overall structure.

[0006] In a possible design, a spring is installed below the push button, and two ends of the spring press against the bottom of the blind hole and the push button respectively.

[0007] With the above design, the spring provides elastic support for the pop-up button, ensuring that the pop-up button quickly returns to its original position after being compressed, and ensuring that the pop-up button is always pre-pressed on the corresponding contact surface, so that the pop-up button can maintain good elastic performance throughout the entire use cycle, and maintain stable contact pressure even under long-term use or frequent operation.

[0008] In a possible design, an axial guide hole is opened on the hole wall of the blind hole, and the guide edge slides in the guide hole and abuts against the top surface of the guide hole when the push button is at the upper limit of movement.

[0009] The above design ensures that the spring button slides smoothly along the axial direction during the up and down movement, avoids lateral deviation or shaking, and prevents unnecessary abnormal noise at this position. At the same time, the internal situation of the blind hole can be viewed through the guide hole. Once it is found that the spring button is not moving smoothly or there is a foreign object stuck, the maintenance personnel can easily clean or adjust the guide hole and guide edge without complicated disassembly.

[0010] In a possible design, the outer wall of the push button and the hole wall of the blind hole are respectively provided with limit blocks, and the two limit blocks abut against each other when the push button moves to the lower limit.

[0011] The above design ensures that the spring button has a certain lower limit of movement, thereby preventing the spring button from being damaged due to excessive movement, thereby enhancing the structural reliability.

[0012] In a possible design, a cone with a small bottom and a large top is provided at the bottom of the push button, a strip hole is opened upward from the bottom of the push button in the radial direction, and the top end of the spring is sleeved outside the cone.

[0013] With the above design, the spring is elastically sleeved on the frustum, so that the spring and the frustum can remain connected, preventing the spring from detaching. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1-4 The illustrated automobile seat toggle switch includes a handle 1. The handle 1 can be turned to switch the state of the switch. A blind hole 11 is provided downward on the top surface of the handle 1. A push button 2 is arranged in the blind hole 11. The push button 2 is elastically and movably installed in the blind hole 11. The top of the push button 2 protrudes upward or partially exposes from the top surface of the handle 1. In this way, the exposed part of the push button 2 can fill the small gap between the top of the handle 1 and its corresponding contact surface, which is equivalent to lengthening the length of the handle 1. The length can be elastically floating according to the installation environment, so that the push button 2 is always pre-pressed on the corresponding contact surface. In order to ensure the stability of the movement trajectory of the push button 2 and prevent the push button 2 from generating a large abnormal sound between the push button 2 and the blind hole 11, the push button 2 is provided with a guide ridge 21. The guide ridge 21 and the hole wall of the blind hole 11 abut against each other when the push button 2 is at the upper limit of its movement, so as to guide the floating trajectory of the push button 2 and prevent the push button 2 from separating from the handle 1.

[0020] A spring 3 is installed below the push button 2, and the two ends of the spring 3 are pressed against the bottom of the blind hole 11 and the push button 2 respectively. A cone 22 with a small bottom and a large top is set at the bottom of the push button 2, and the top of the spring 3 is sleeved outside the cone 22. In order to prevent the spring 3 from detaching, a strip hole 23 is opened upward from the bottom of the push button 2 to pass through the radial direction of the push button 2, so that the cone 22 obtains a certain radial elastic support force, so that the spring 3 and the cone 22 can remain connected. The spring 3 ensures that the push button 2 quickly returns to its original position after being pressed, so that the push button 2 can maintain good elastic performance throughout the entire use cycle.

[0021] An axial guide hole 12 is provided on the hole wall of the blind hole 11, and the guide rib 21 slides in the guide hole 12 along the setting direction of the guide hole 12, and abuts against the top surface of the guide hole 12 when the push button 2 is at the upper limit of its movement. This ensures that the push button 2 slides smoothly along the axial direction during the up and down movement, and the limiting guide rib 21 prevents the push button 2 from exceeding the range of movement, thereby preventing the push button 2 from being separated from the handle 1.

[0022] The outer wall of the push button 2 and the hole wall of the blind hole 11 are respectively provided with stop blocks 24, which abut against each other when the push button 2 moves to the lower limit. At this time, the top surface of the handle 1 is not above the top of the push button 2, and the handle 1 with higher structural strength provides support force, thereby preventing the push button 2 from moving downward excessively, thus avoiding damage to the mechanism or functional failure, and ensuring a stable and reliable operating state.
