Description

Technical Field

[0001] This application relates to the technical field of automotive button devices, and in particular to a switch for an automotive center console panel. Background Technology

[0002] In the automotive industry, center console buttons serve as a crucial human-machine interface, offering significant advantages in terms of ease of operation and reliability. For critical operations and frequently used functions, using center console buttons not only ensures driving safety but also enhances operational convenience. To optimize the user experience, the layout design of center console buttons emphasizes rationality and user-friendliness, with important physical buttons often placed in easily accessible locations, such as below the center console or near the steering wheel, facilitating blind operation by the driver while driving.

[0003] In related technologies, a car center console switch includes a base plate, a circuit board, a cover, and buttons. Two limit switches are fixed on the circuit board, and the buttons are rotatably mounted on the cover. Inside the cover, trigger rods are installed above the two limit switches, with the upper ends of the two trigger rods located on opposite edges of the bottom side of the buttons. When the button is pressed, the trigger rods are squeezed and slide towards the base plate, triggering the limit switches. When the pressing stops, the limit switches automatically reset, causing the trigger rods and buttons to reset as well.

[0004] However, different users have different pressing pressure levels. If a user presses the button with too much force, it may damage the device. Prolonged pressure can damage the lower end of the trigger lever, potentially harming the limit switch and significantly reducing its lifespan. This issue not only affects user experience but may also increase maintenance costs, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a car center console switch that solves the problem of damage to the center console switch caused by excessive pressing pressure in the aforementioned related technologies.

[0006] The technical solution for a car center console switch provided in this application is as follows: A car center console switch includes a base plate, a circuit board fixed to the base plate, a cover mounted above the base plate, and a button. Two limit switches are fixed on the side of the circuit board facing the cover. Two trigger rods with one end extending above the two limit switches are slidably mounted on the cover. The middle part of the button is rotatably connected to the side of the cover away from the base plate. The ends of the two trigger rods away from the base plate pass through the cover and extend relative to each other to below the button. Two limiting plates are fixed on the side of the button near the cover, respectively located above the two trigger rods. The cover has limiting grooves for the limiting plates to rotate and engage. When the button is rotated, it presses the trigger rods to trigger the limit switches. When the limit switches are triggered, the limiting plates abut against the bottom side of the corresponding limiting grooves.

[0007] By adopting the above technical solution, as the button is pressed, the limiting plate also rotates with the button until the limiting plate abuts against the limiting groove, at which point the button pressing process is completed. First, it effectively avoids the problem of device damage that may be caused by the difference in pressing force of different users. No matter how much force the user applies, once the limit switch is triggered, the abutting between the limiting plate and the bottom side of the limiting groove will limit the button to rotate further, preventing damage to the button and internal devices, such as the limit switch, due to excessive pressing.

[0008] Optionally, an extension plate is fixed on both opposite edges of the side of the button facing the cover, and a protrusion is fixed on the side of the cover away from the bottom plate. A first through hole is opened on the protrusion, and a circular protrusion is fixed on the two inner walls of the protrusion opposite to the first through hole. The extension plate is opened with a circular through hole for the circular protrusion to be inserted, and the button can rotate around the axis of the circular protrusion.

[0009] By adopting the above technical solution, the circular protrusion is inserted into the circular through hole. When the button is pressed, the extension plate can rotate accordingly with the rotation of the button. From the perspective of ease of operation, this rotating connection method provides users with a smooth and natural operating experience. When the driver performs blind operation while driving, he can easily realize the corresponding function by rotating the button, thus improving operating efficiency.

[0010] Optionally, the protrusion is provided with a guide hole through which the trigger rod passes and slides.

[0011] By adopting the above technical solution, the trigger rod moves accordingly when the button is pressed through the guide hole. In terms of operational precision, the guide hole provides the trigger rod with a precise movement trajectory. When the driver presses the button to trigger the limit switch, the trigger rod can move stably and accurately towards the limit switch under the constraint of the guide hole, effectively avoiding the trigger rod from deviating or getting stuck during the sliding process, ensuring that the limit switch is accurately triggered, and improving the reliability and stability of the operation.

[0012] Optionally, a reinforcing rib is fixed on the side of the extension plate away from the circular protrusion.

[0013] By adopting the above technical solution, from the perspective of structural strength, the reinforcing ribs greatly enhance the overall strength of the extension plate. Since the buttons are frequently pressed during daily use, the extension plate, as a key component supporting the rotation of the buttons, is prone to deformation or even breakage due to long-term stress. The addition of the reinforcing ribs effectively disperses the pressure it bears, greatly improves the extension plate's ability to resist deformation and breakage, and ensures the stability of the button rotation structure.

[0014] Optionally, a first guide slope is provided on the side edge of the extension plate near the circular protrusion, and the first guide slope is located on the side edge of the extension plate away from the button.

[0015] By adopting the above technical solution, the design of the first guide slope allows the button and the protrusion to slide and install along the first guide slope, allowing the button to be better installed on the protrusion. In terms of installation convenience, when assembling the product, during the process of workers installing and matching the extension plate with the circular protrusion, the first guide slope can automatically guide the extension plate to accurately and quickly align with the circular protrusion due to its inclined structure, which significantly reduces the installation difficulty, improves the assembly efficiency, and reduces the time cost of manual operation.

[0016] Optionally, the end of the extension plate away from the button has rounded corners.

[0017] By adopting the above technical solutions, from a safety perspective, during the product assembly process, workers frequently come into contact with parts, and sharp edges and corners can easily cause scratches and other accidental injuries. The rounded corner design effectively eliminates this safety hazard and ensures the safety of workers' operations.

[0018] Optionally, a circular abutment plate is fixed on the end of the trigger rod facing the limit switch, and the circular abutment plate presses the limit switch when the trigger rod is pressed.

[0019] By adopting the above technical solution, when the button is pressed and rotated, the limit plate presses the trigger rod, and the trigger rod slides along the guide hole to press the limit switch, completing the pressing process. In terms of signal transmission accuracy, the circular abutment plate significantly increases the contact area between the trigger rod and the limit switch. When the trigger rod is pressed and the circular abutment plate presses the limit switch, the button signal can be transmitted more efficiently and stably, greatly reducing the probability of signal interruption or mistransmission due to poor contact, ensuring that user operation commands can be executed accurately, and improving the reliability of the central control system.

[0020] Optionally, a plurality of trapezoidal locking blocks are fixed on the two opposite outer edges of the base plate, and the shell cover is provided with limiting holes for the trapezoidal locking blocks to be engaged.

[0021] By adopting the above technical solution, the trapezoidal locking block can play an automatic guiding role when assembling the base plate and the shell cover. When the two are close to each other, the trapezoidal locking block and the corresponding position of the shell cover make contact with each other, guiding the trapezoidal locking block to quickly and accurately lock into the limiting hole, which greatly simplifies the assembly process, reduces the difficulty of operation for workers, improves the assembly efficiency on the production line, and reduces labor costs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. It avoids damage to the hollow panel switch in a short time. The first limiting groove limits the limiting plate, so that the rotation of the button is within the design range. It will not cause damage to the central control panel switch due to excessive force by the user, reduce maintenance costs, reduce maintenance frequency, extend the overall service life of the product, and reduce after-sales maintenance investment. 2. Greatly improves assembly convenience. The trapezoidal locking block plays an automatic guiding role. When assembling the base plate and the shell cover, the trapezoidal locking block is guided to quickly and accurately engage in the limiting hole, simplifying the operation process, reducing the difficulty of operation for workers, significantly improving the assembly efficiency on the production line, and effectively reducing labor costs. 3. Enhance user experience: A robust connection makes button operation feedback more stable, allowing users to feel a consistent and reliable touch when pressing the buttons, avoiding operational abnormalities caused by loose parts, making operation smoother while driving, and improving satisfaction with the car's central control system.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example: Reference Figure 1 , Figure 2 and Figure 3 A car center console switch includes a base plate 1, a circuit board 3 fixed on the base plate 1, a cover 2 mounted on the base plate 1, and nine buttons 6; the base plate 1, the cover 2, and the circuit board 3 are all elongated strips in shape, the base plate 1 and the cover 2 are fixedly connected by bolts, and the circuit board 3 is also fixed to the side of the base plate 1 facing the cover 2 by bolts. Nine buttons 6 are mounted side by side on the outer surface of the cover 2. The middle part of the buttons 6 is rotatably connected to the side of the cover 2 away from the base plate 1. Nine sets of limit switches 5 corresponding to the nine buttons 6 are integrally formed on the side of the circuit board 3 facing the cover 2. Each set of limit switches 5 has two switches. Two trigger rods 4 are slidably mounted on the cover 2, with one end extending above the two limit switches 5. The ends of the two trigger rods 4 away from the base plate 1 pass through the cover 2 and extend to the bottom of the buttons 6. When the buttons 6 are rotated, they press the trigger rods 4 to trigger the limit switches 5.

[0028] Reference Figure 3 and Figure 4On the side of the button 6 facing the cover 2, there are two integrally formed extension plates 61. On the side of the cover 2 away from the bottom plate 1, there are nine protrusions 21 corresponding to the button 6. The protrusions 21 are provided with a first through hole 211. On the two inner walls of the protrusions 21 opposite to the first through hole 211, there are two integrally formed circular protrusions 212. The extension plate 61 is provided with a circular through hole 613 for the circular protrusions 212 to be inserted. The button 6 can rotate around the axis of the circular protrusions 212.

[0029] Reference Figure 3 The button 6 has two limiting plates 62 integrally formed on the side near the cover 2, which are located above the two trigger rods 4 respectively. The cover 2 has a limiting groove 213 on the protrusion 21 for the limiting plates 62 to rotate and be inserted. When the limit switch 5 is triggered, the limit plate 62 abuts against the bottom side of the corresponding limit groove 213. Since different users can use different amounts of force, this design can prevent damage to the button 6 and the internal device of the button 6 due to excessive force from the user.

[0030] Reference Figure 4 Four reinforcing ribs 611 are integrally formed on the extension plates 61 on opposite sides away from the circular protrusion 212, which increases the strength of the extension plates 61 and makes them less prone to breakage. A first guide slope 612 is provided on the side edge of the extension plate 61 near the circular protrusion 212, and the first guide slope 612 is located on the side edge of the extension plate 61 away from the button 6. The end of the extension plate 61 away from the button 6 is rounded, and this rounded corner design prevents the assembler from being injured during the work process.

[0031] Reference Figure 5 The inner bottom surface of button 6 near extension plate 61 has a marking area 63, which is marked with the corresponding installation number. The marking of the number in marking area 63 allows the assembler to quickly sort and assemble button 6 according to the corresponding number, reducing the assembly error rate and speeding up the assembler's efficiency.

[0032] Reference Figure 2 and Figure 3 The protrusion 21 has a guide hole 214 for the trigger rod 4 to pass through and slide. A circular abutment plate 41 is integrally formed on the end of the trigger rod 4 facing the limit switch 5. When the user rotates the button 6, it will press the trigger rod 4. During this process, the circular abutment plate 41 presses the limit switch 5. The design of the circular abutment plate 41 makes the contact area between the trigger rod 4 and the limit switch 5 larger, which can more fully and effectively transmit the button 6 signal, improve the user experience, and avoid reducing the user's work efficiency due to poor contact.

[0033] Reference Figure 6 and Figure 7Eight trapezoidal blocks 11 are integrally formed on the two opposite outer edges of the base plate 1, with four on each side. Eight limiting holes 22 are provided on the cover 2 for the trapezoidal blocks 11 to be inserted, with four on each side. A second guide slope 23 is provided on the side edge of the cover 2 near the base plate 1. When the base plate 1 and the shell cover 2 are assembled, the trapezoidal locking block 11 abuts against the second guide inclined surface 23 and slides relative to it until the trapezoidal locking block 11 is engaged in the limiting hole 22, thereby realizing the initial assembly of the base plate 1 and the shell cover 2, which is convenient for further fixing with bolts later.

[0034] Reference Figure 6 and Figure 8 On the side of the base plate 1 away from the circuit board 3, there is an integrally formed connection port 12 for inserting external cables; on the side of the base plate 1 away from the cover 2, there are two opposing first fixing plates 13, the first fixing plates 13 are perpendicular to the base plate 1, and the first fixing plates 13 are provided with first fixing through holes 131. The cover 2 has a second fixing plate 24 integrally formed on both sides. The second fixing plate 24 is parallel to the upper side of the cover 2. The second fixing plate 24 has a second fixing through hole 241. When the switch is installed and fixed, several bolts can be used to pass through the first fixing through hole 131 and the second fixing through hole 241 respectively to fix the central control panel switch to the central control panel in the driver's cab of the vehicle.

[0035] The implementation principle of this application embodiment is as follows: During the use of the central control panel switch, button 6 is pressed by the user's finger, causing the extension plate 61 to rotate around the axis of the circular protrusion 212. The limiting plate 62 also presses the trigger rod 4 down along the guide hole 214. At the same time, the circular abutting plate 41 also presses the limit switch 5. When fully pressed, the limiting plate 62 reaches the bottom side of the limiting groove 213. If the user wants to continue pressing button 6 down, since the limiting plate 62 and the bottom side of the limiting groove 213 are in contact with each other, button 6 will remain in this state and will be difficult to continue rotating downward. When the user stops pressing, the limit switch 5 resets, causing the trigger lever 4 to rebound in the opposite direction. The trigger lever 4 then slides in the guide hole 214 in the opposite direction to when it was pressed. As the trigger lever 4 slides, it pushes against the limiting plate 62 away from the limiting groove 213 until it returns to its initial position, completing the process of the central control panel switch executing the command of button 6 by pressing button 6.
