Abstract
Description
Technical Field
[0001] This application relates to the technical field of parking switches, and in particular to a vibration-resistant, enhanced, and highly protective electronic parking switch assembly. Background Technology
[0002] With the development of the modern automotive industry, electronic parking brake systems have gradually replaced traditional handbrake systems, becoming one of the key technologies for improving vehicle safety and convenience. Currently, common electronic parking brake switch assemblies on the market mainly include various forms such as push-button and rotary types. These systems generally emphasize functionality and user experience in their design, but their reliability and stability in harsh environments still need improvement.
[0003] Push-button electronic parking switches activate or deactivate the parking brake by pressing a button. They are usually equipped with an indicator light to show the status. The reset of push-button electronic parking switches is usually achieved by a spring. However, over time, the spring may fail, causing the button to loosen under high-frequency use. Utility Model Content
[0004] In order to improve the problem that the spring of the parking switch may fail during long-term use, making the button prone to loosening under high-frequency use, this application provides a vibration-resistant and reinforced high-protection electronic parking switch assembly.
[0005] The vibration-resistant and enhanced high-protection electronic parking switch assembly provided in this application adopts the following technical solution:
[0006] A vibration-resistant and reinforced high-protection electronic parking switch assembly includes a base, a mounting shell on the base, a fixing member on the base for fixed connection with the mounting shell, a button shell on the top of the mounting shell, an electronic parking button rotatably mounted inside the button shell, a circuit board on the top surface of the base, a brake-on micro switch and a brake-off micro switch on the circuit board, a drive board inside the mounting shell, a starting block one and a starting block two on the bottom surface of the drive board for respectively activating the brake-on micro switch and the brake-off micro switch, a drive component on the electronic parking button for driving the drive board to move, and a reset member on the circuit board for resetting the drive board.
[0007] By adopting the above technical solution, during use, pressing down on the electronic parking brake button moves the drive assembly, which in turn moves the drive board, which in turn moves the starter block one. Starter block one then triggers the brake, activating the microswitch, thus putting the vehicle in a braking state when parked. To release the brake, pulling the electronic parking brake button upwards moves the drive assembly in the opposite direction, which in turn moves the drive board in the opposite direction. The drive board then moves the starter block two, triggering the brake and releasing the microswitch. Simultaneously, a reset component resets the drive board. When the electronic parking brake button is not pressed or pulled, the reset component limits the drive board, reducing the possibility of the electronic parking brake button becoming loose.
[0008] Preferably, the top surface of the drive board has a through groove, and a reset plate is fixed to one end of the bottom surface of the drive board. The reset component includes a mounting plate one and a mounting plate two fixed to the top surface of the circuit board. The mounting plate one and the mounting plate two are respectively located on both sides of the reset plate. The top end of the mounting plate two passes through the through groove. Silicone 1 is fixed to the opposite sides of the mounting plate one and the mounting plate two. The two sides of the reset plate abut against the silicone 1 on the mounting plate one and the mounting plate two, respectively.
[0009] By adopting the above technical solution, during use, pressing down on the electronic parking brake button moves the drive assembly, causing the drive assembly to move the drive board closer to the mounting plate. The silicone seal on the mounting plate is compressed. When the electronic parking brake button is released, the silicone seal on the mounting plate returns to its initial state under its own elasticity, thus driving the reset plate to move, which in turn moves the drive board to its initial state. When it is necessary to release the brake, pulling up on the electronic parking brake button causes the drive assembly to move in the opposite direction. The drive assembly moves the drive board in the opposite direction, causing the drive board to compress the silicone rubber on the mounting plate. When the electronic parking brake button is released, the silicone rubber on the mounting plate returns to its initial state under its own elasticity, thereby driving the reset plate to move. The reset plate then moves the drive board back to its initial state. When the electronic parking brake button is not pressed or pulled, the silicone rubber on the mounting plate and the mounting plate clamp and fix the reset plate, thereby reducing the possibility of the drive board shaking when the vehicle is in motion, and thus improving the shock resistance of the electronic parking brake switch.
[0010] Preferably, the drive assembly includes a push rod fixed to the bottom surface of the electronic parking button, the bottom surface of the push rod has a groove, and a movable block is fixed to the top surface of the drive plate, the top end of the movable block being inserted into the groove.
[0011] By adopting the above technical solution, when the electronic parking button is pressed and pulled, the electronic parking button drives the push rod to rotate, thereby causing the inner side of the groove to drive the moving block to move, and the moving block to drive the drive block to move.
[0012] Preferably, the bottom surfaces of both the first and second starting blocks are provided with inclined surfaces.
[0013] By adopting the above technical solution, inclined surfaces are opened on the bottom surfaces of starting block one and starting block two. When the drive plate moves starting block one and starting block two, it is convenient for the inclined surfaces to trigger the braking micro switch to open and the braking micro switch to close.
[0014] Preferably, an automatic parking button is installed inside the mounting housing, and a silicone rubber compound is fixed to the top surface of the circuit board, with the top of the silicone rubber compound abutting against the bottom of the automatic parking button.
[0015] By adopting the above technical solution, silicone rubber is placed at the bottom of the automatic parking button to press the automatic parking button firmly, thereby reducing the possibility of the automatic parking button becoming loose.
[0016] Preferably, the fastener includes a buckle disposed on the side of the base, and the side of the mounting shell has a slot in which the buckle is engaged.
[0017] By adopting the above technical solution, the mounting shell and the base are fixed by snap-fit, which facilitates the installation of the mounting shell and the base.
[0018] Preferably, the top surface of the base is provided with a plurality of positioning blocks, and the bottom surface of the circuit board is provided with a plurality of positioning slots, and the positioning blocks are inserted into the positioning slots.
[0019] By adopting the above technical solution, when the circuit board is placed on the base, the positioning block on the base is inserted into the positioning groove on the bottom surface of the circuit board, thereby reducing the possibility of the circuit board moving when the mounting shell is installed on the base.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. In use, pressing down on the electronic parking brake button moves the drive assembly, which in turn moves the drive board, which in turn moves the starter block one. The starter block one then triggers the brake and activates the micro switch, thus putting the vehicle in a braking state when parked. To release the brake, pulling up on the electronic parking brake button moves the drive assembly in the opposite direction, which in turn moves the drive board in the opposite direction. The drive board then moves the starter block two, which triggers the brake and releases the micro switch. The reset component resets the drive board. When the electronic parking brake button is not pressed or pulled, the reset component limits the drive board, thus reducing the possibility of the electronic parking brake button becoming loose.
[0022] 2. In use, pressing the electronic parking brake button downwards moves the drive assembly, causing the drive board to move closer to mounting plate one. The silicone seal on mounting plate one is compressed. When the electronic parking brake button is released, the silicone seal on mounting plate one returns to its initial state due to its elasticity, thus driving the reset plate to move, which in turn moves the drive board to its initial state. To release the brake, pulling the electronic parking brake button upwards moves the drive assembly in the opposite direction, releasing the brake. The drive component drives the drive board to move in the opposite direction, causing the drive board to press against the silicone rubber on the mounting plate 2. The silicone rubber on the mounting plate 2 is in a compressed state. When the electronic parking brake button is released, the silicone rubber on the mounting plate 2 returns to its initial state under its own elastic force, thereby driving the reset plate to move. The reset plate then drives the drive board to move to its initial state. When the electronic parking brake button is not pressed or pulled, the silicone rubber on the mounting plate 1 and the mounting plate 2 clamp and fix the reset plate, thereby reducing the possibility of the drive board shaking when the vehicle is in motion, and thus improving the shock resistance of the electronic parking brake switch.
[0023] 3. An inclined surface is provided on the bottom surface of starting block one and starting block two. When the drive plate moves starting block one and starting block two, the inclined surface can trigger the brake to open the micro switch and release the brake. Attached Figure Description

Detailed Implementation
[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0029] This application discloses a vibration-enhanced, high-protection electronic parking switch assembly.
[0030] Reference Figure 1 and Figure 2 A vibration-resistant and reinforced high-protection electronic parking switch assembly includes a base 1, a mounting shell 11 on the base 1, buckles 12 fixed on both sides of the base 1, and slots 13 opened on both sides of the mounting shell 11, with the buckles 12 snapped into the slots 13.
[0031] Reference Figure 1 , Figure 2 and Figure 3 A circuit board 2 is mounted on the top surface of the base 1. Positioning grooves 21 are formed at the bottom edge of the circuit board 2, and positioning blocks 22 are fixed at the top edge of the base 1, inserted into the positioning grooves 21. A brake-on microswitch 23 and a brake-off microswitch 24 are fixed on the top surface of the circuit board 2. A drive plate 25 is housed inside the mounting housing 11, located above the circuit board 2, and slidably connected to the inner wall of the mounting housing 11. The bottom surface of the drive plate 25 is provided with a first starter block 26 and a second starter block 27 for respectively activating the brake-on microswitch 23 and the brake-off microswitch. Both the first starter block 26 and the second starter block 27 have inclined surfaces 28 on their bottom surfaces.
[0032] Reference Figure 1 and Figure 2 The top surface of the drive board 25 has a through groove 3, and a reset plate 31 is fixed to one end of the bottom surface of the drive board 25. A mounting plate 32 and a mounting plate 33 are fixed to the top surface of the circuit board 2. The mounting plate 32 and the mounting plate 33 are located on opposite sides of the reset plate 31, with the top end of the mounting plate 33 passing through the through groove 3. Two silicone rubbers 34 are fixed to the opposite sides of the mounting plate 32 and the mounting plate 33, respectively. The two sides of the reset plate 31 abut against the two silicone rubbers 34 on the mounting plate 32 and the mounting plate 33.
[0033] Reference Figure 1 and Figure 2 An electronic parking brake button 41 is rotatably mounted inside the top of the mounting housing 11. Two parallel push rods 42 are fixed to the bottom surface of the electronic parking brake button 41, and grooves 43 are formed on the bottom surface of the push rods 42. Two moving blocks 44 are fixed to the top surface of the drive plate 25, corresponding to the two drive plates 25, with the top ends of the moving blocks 44 inserted into the grooves 43. An automatic parking brake button 45 is installed inside the mounting housing 11. A silicone rubber 46 is fixed to the top surface of the circuit board 2, with the top end of the silicone rubber 46 abutting against the bottom end of the automatic parking brake button 45.
[0034] The implementation principle of the vibration-resistant and reinforced high-protection electronic parking switch assembly in this application embodiment is as follows: During use, pressing down on the electronic parking button 41 causes the push rod 42 to rotate, which in turn drives the moving block 44 to move. The moving block 44 then drives the drive plate 25 to move, which in turn drives the starting block 26 to move. This causes the inclined surface 28 on the starting block 26 to trigger the brake-activated microswitch 23, thus putting the vehicle in a braking state when parking. When the electronic parking button 41 is released, the reset plate 31, under the elastic force of the silicone 34 on the mounting plate 32, moves the drive plate 25 to its initial position. When it is necessary to release the brake, pressing the electronic parking button... Pulling 41 upwards causes the electronic parking brake button 41 to rotate the push rod 42 in the opposite direction, which in turn drives the moving block 44 to move in the opposite direction. The moving block 44 then drives the drive plate 25 to move in the opposite direction, which in turn drives the starting block 27 to move. This causes the inclined surface 28 on the starting block 27 to trigger the brake release micro switch 24. When the electronic parking brake button 41 is released, the reset plate 31, under the elastic force of the silicone 34 on the mounting plate 23, moves the drive plate 25 to its initial position. When the electronic parking brake button 41 is not pressed or pulled, the silicone 34 on the mounting plate 1 and mounting plate 23 fixes the reset plate 31, thereby reducing the possibility of the electronic parking brake button 41 becoming loose.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
