Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a two-way module for automotive seat adjustment switches. Background Technology

[0002] Car seat adjustment switches are one of the most frequently used functions while driving. Understanding their location and function can greatly improve driving comfort and safety. Generally, car seat adjustments are divided into two types: manual mechanical and electric. Modern cars, especially mid-to-high-end models, commonly use electric adjustment.

[0003] For example, patent application number 202422549962.4 published on the China Patent Network, entitled "Automotive Seat Adjustment Switch," includes: at least two independent switch modules, each switch module having a PCB circuit board and a control switch connected to the PCB circuit board; a button detachably connected to the corresponding switch module, the button triggering the control switch on the corresponding switch module; a wiring harness assembly including signal lines connected to the PCB circuit boards of each switch module; and a connector electrically connected to any one or more of the at least two switch modules. The switch modules of this utility model are independent components connected by a wiring harness connection mechanism. The various switch modules can form a platform component, breaking the limitation of traditional switches being unusable due to their shape, effectively saving development resources and improving development efficiency.

[0004] However, the existing rocker switch has a relatively simple structure. Under repeated friction, the coating or material on the surface of the sliding contact electrode will gradually wear down and fail, resulting in increased or unstable contact resistance. At the same time, the metal or carbon fragments generated by the wear may fall into the contact point or other mechanical parts, causing additional mechanical jamming, poor contact, or even short circuit risk. Moreover, after long-term reciprocating bending, the electrode, as an elastic element, will experience metal fatigue, weaken its elasticity, and cause a decrease in contact pressure, ultimately failing to conduct reliably.

[0005] Therefore, it is necessary to redesign and modify the one-way rocker-type car seat adjustment switch. Summary of the Invention

[0006] To address the problems mentioned in the background art, the present invention aims to provide a two-way silicone module for automotive seat adjustment switches, which has the advantage of improving reliability. It solves the problems of existing rocker switches having a relatively simple structure, where the coating or material on the surface of the sliding contact electrodes gradually wears down and fails under repeated friction, leading to increased or unstable contact resistance. At the same time, metal or carbon fragments generated by wear may fall into the contact point or other mechanical parts, causing additional mechanical jamming, poor contact, or even short circuit risk.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A two-way silicone module for a car seat adjustment switch includes a module upper shell. A module silicone pad is connected to the bottom of the upper shell, and a PCB circuit board is connected to the bottom of the silicone pad. Module pressure blocks are connected to both sides of the top of the silicone pad, and a module rocker arm is connected to the top of each pressure block. The rocker arm can control the module switch to start via two-way horizontal displacement. This invention establishes the basic structure of the switch by incorporating the module silicone pad, pressure blocks, and rocker arm within the upper shell, and by adding a button adjustment structure on the top of the rocker arm. This allows the rocker arm to trigger the module switch via two-way horizontal displacement, while the adjustment structure precisely controls the displacement of the rocker arm. As a preferred embodiment of the present invention, a module silicone is fixedly connected to the bottom of the inner wall of the module housing. Module pressure blocks are connected to both sides of the top of the module silicone, and a PCB circuit board is connected to the bottom. A module swing arm is connected to the top of the module pressure block, and an adjustment button is connected to the top of the module swing arm. The adjustment button can control the module switch to start by moving the swing arm in two horizontal directions.

[0008] As a preferred embodiment of the present invention, the adjustment mechanism is a button. The bottom groove of the button is fixedly connected to the top ball head of the module swing rod. Both sides of the button are set to be open, and the button can move horizontally in two directions. The displacement drives the module swing rod to perform transmission adjustment.

[0009] As a preferred embodiment of the present invention, the circular shafts on both sides of the module swing arm are fixedly connected in the circular grooves of the module housing. When the button moves horizontally in both directions, it drives the module swing arm to rotate around the circular shafts, thereby causing the contact points at both ends of the bottom of the module swing arm to move up and down.

[0010] Preferably, the bottom two contact points of the module swing arm are in contact with the module pressure block. The slider of the module pressure block is installed in the slide rail of the module housing. When the bottom two contact points of the module swing arm move downward, they contact and press the module pressure block, causing it to move downward along the slide rail and further contact the module silicone connected to the bottom. As a preferred embodiment of the present invention, the bottom of the module pressing block is connected to the module silicone contact. When the module pressing block moves downward, it contacts and presses the corresponding module silicone contact, causing the contact to compress and move downward. When it fully contacts the PCB circuit board at the bottom of the module silicone, the circuit of the PCB board forms a closed loop, and the circuit will be turned on.

[0011] In a preferred embodiment of the present invention, when the finger releases force, the silicone contact of the module springs back to its original position, pushing the connected module pressure block to move upward back to its original position. Furthermore, the upwardly moving module pressure block pushes the circular axis of the module swing rod to move upward back to its original position, thereby driving the connected button to reset.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention forms the basic architecture of the switch by setting module silicone, PCB circuit board, module pressure block and module rocker arm inside the module shell, and setting a button adjustment structure on the top of the module rocker arm. This allows the button to trigger the module rocker arm by horizontal displacement, and the adjustment structure can precisely control the displacement of the module rocker arm. This is fundamentally different from the traditional sliding contact switch and provides a structural premise for solving the reliability problems caused by repeated friction leading to contact wear, debris generation, and thus increased contact resistance, jamming or short circuit.

[0013] 2. This invention sets up round shafts on both sides of the module swing arm to be fixedly engaged in the round grooves of the module shell. The module swing arm rotates around the round shafts, strictly constraining the movement of the module swing arm to the movement of the round shafts, ensuring the accuracy and consistency of the triggering action, effectively isolating the interference of movement or vibration in other directions, and making the triggering process of the module swing arm stable and reliable.

[0014] 3. In this invention, the slider of the module pressure block is installed in the slide rail of the module housing. When the two contacts at the bottom of the module swing arm move downward to contact and press the module pressure block, the slide rail will restrict the module pressure block to move straight downward. This ensures that the module pressure block can only slide along a predetermined straight trajectory when under force, preventing it from swaying, jamming, or generating unexpected friction with other components during the movement. This improves the smoothness, accuracy, and durability of the entire transmission system.

[0015] 4. This invention utilizes modular silicone, where the silicone contacts have a spring-back force after compression. When the user releases their finger, the modular silicone contacts spring back and reset, pushing the connected modular pressure block upwards. Furthermore, the upwardly resetting modular pressure block pushes the module rocker arm's circular axis upwards to reset, thereby resetting the connected button. This ensures that the switch can stably return to its original position when there is no operation, preparing for the next operation, while also providing the user with a clear, neutral tactile feel.

[0016] 5. By using a modular housing, this invention achieves effective sealing of the internal moving parts area. Without interfering with the normal swing of the lever, it can effectively prevent external dust, liquids and other contaminants from entering the switch. At the same time, the use of modular silicone can also absorb some impact and vibration, which can protect the internal mechanism and reduce operating noise. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0020] A two-way module for an automotive seat adjustment switch includes a module housing 4, module silicone 3, module pressure block 2, PCB circuit board 5, module lever 1, and adjustment button 6. The adjustment button controls the module switch by moving the lever in two horizontal directions. The adjustment structure precisely controls the displacement of the module lever, fundamentally differentiating it from traditional sliding contact switches. This provides a structural basis for solving reliability problems such as contact wear and debris generation caused by repeated friction, leading to increased contact resistance, jamming, or short circuits.

[0021] The adjustment mechanism is button 6. The bottom groove 11 of button 6 is fixedly connected to the top ball head 7 of module swing arm 1. Both sides of button 6 are open, allowing it to move horizontally in two directions. This displacement drives the module swing arm 1 for transmission adjustment. The circular shafts 8 on both sides of module swing arm 1 are fixedly connected to the circular grooves of module housing 4, strictly constraining the movement of module swing arm to the movement of the circular shafts. This ensures the accuracy and consistency of the triggering action and effectively isolates interference from movement or vibration in other directions, making the triggering process of module swing arm stable and reliable. When button 6 moves horizontally in two directions, it drives module swing arm 1 to rotate around the circular shaft 8, thereby causing the contact points 9 at both ends of the bottom of module swing arm 1 to move stably up and down.

[0022] The bottom two contact points 9 of the module rocker arm 1 are in contact with the module pressure block 2. The slider of the module pressure block 2 is installed in the slide rail of the module housing 4. When the bottom two contact points 9 of the module rocker arm 1 move downward, they contact and press the module pressure block 2 to make it move downward along the slide rail. The slide rail restricts the module pressure block to move straight downward, ensuring that the module pressure block can only slide along a predetermined straight trajectory when under force. This prevents it from swaying, jamming, or generating unexpected friction with other components during the movement, thereby improving the smoothness, accuracy, and durability of the entire transmission system.

[0023] The silicone contacts have a spring-back reset force after compression. When the user releases the force by releasing their finger, the silicone contacts of the module spring back to their original position, pushing the connected module pressure block to move upward back to its original position. Furthermore, the upward-moving module pressure block pushes the circular axis of the module rocker arm to move upward back to its original position, thereby driving the connected button to reset. This ensures that the switch can stably return to its original position when there is no operation, preparing for the next operation, while providing the user with a clear neutral tactile feel.

[0024] The bottom of the module pressure block 2 is connected to the module silicone 3 contact 10. When the module pressure block 2 moves downward, it contacts and presses the corresponding module silicone 3 contact 10, causing the contact 10 to compress and move downward. When it fully contacts the PCB circuit board 5 at the bottom of the module silicone 3, the circuit of the PCB board forms a closed loop, and the circuit is then connected. When the finger is released, the module silicone 3 contact 10, after compression, has a rebound force, which pushes the connected module pressure block 2 to move upward back to its original position. Furthermore, the upward-moving module pressure block 2 pushes the circular axis of the module rocker arm 1 to move upward and reset, thereby driving the connected button 6 to reset. This ensures that the switch can stably return to its original position when there is no operation, preparing for the next operation, while providing the user with a clear neutral tactile feel.
