Description

Technical Field

[0001] This utility model relates to the field of vehicle electronic control switch structure, specifically to a built-in vehicle control switch. Background Technology

[0002] When driving, a driver (with a disability in the right lower limb or both lower limbs) uses their left hand to hold the steering wheel and their right hand to operate the brakes and accelerate via an external auxiliary device. In case of an emergency (such as emergency avoidance or brake failure), the electronic parking brake system is required for emergency braking. However, traditional electronic parking brakes use a push-button mechanism. Because the driver lacks lower limb support, in an emergency, if the left hand is controlling the vehicle's direction, the seatbelt may not fully restrain the driver's body, causing slippage. In this situation, blindly pressing the electronic parking brake with the right hand can easily cause the driver to lose control, failing to activate the electronic parking brake system and preventing the vehicle from effectively slowing down, which is quite dangerous.

[0003] Therefore, there is an urgent need to design a built-in vehicle control switch to meet the emergency use needs of disabled drivers. Utility Model Content

[0004] The purpose of this invention is to provide a built-in vehicle control switch that can quickly and accurately trigger the electronic parking brake system by pushing and pulling the drive handle in case of an emergency. It supports both long-press and continuous-point operation modes, thereby ensuring that the driver (especially disabled drivers) can quickly and reliably perform braking operations in emergency situations, effectively improving vehicle safety and braking response speed.

[0005] The technical solution adopted by this utility model to solve the above problems is: a built-in vehicle control switch, including a base, a parking unit, and a drive unit for triggering the parking unit. The drive unit includes a cylindrical housing, a drive shaft is slidably disposed inside the housing, and a drive handle is disposed on the drive shaft to drive it to slide along the inside of the housing. The parking unit is installed and fixed on one side of the housing and includes a parking button. The parking button adopts a spherical structure, and an arc-shaped groove adapted to slide on the drive shaft.

[0006] Preferably, a first return spring is also provided inside the housing, with one end of the first return spring connected to the lower end of the drive shaft and the other end fixed inside the housing.

[0007] Preferably, the drive handle adopts a spherical structure, the drive shaft adopts a hollow structure and is connected to the drive handle, a slider is slidably arranged inside the drive shaft, and an arc-shaped groove has a notch that is connected to the inside of the drive shaft. Squeezing the drive handle drives the slider to slide down to the notch and press the parking button.

[0008] Preferably, a second return spring is provided inside the drive shaft, the lower end of the drive shaft is closed, one end of the second return spring is connected to the slider, and the other end is fixed to the closed end of the drive shaft.

[0009] Preferably, the parking unit further includes a mounting base, the parking button is disposed on the mounting base, a threaded mounting port is provided on one side of the housing, the mounting base is provided with an external thread structure that fits the threaded mounting port, and the mounting base is screwed into the threaded mounting port so that the parking button is inserted into the housing and contacts the arc-shaped groove.

[0010] Preferably, the base includes a fixed panel and a slide block, with the slide block being damped and slidably connected to the fixed panel.

[0011] Compared with the prior art, this utility model has the following advantages and effects:

[0012] This invention replaces the traditional push-button structure with a push-pull drive handle and incorporates built-in first and second return springs, enabling blind operation triggering of the electronic parking brake system in emergency situations. Furthermore, the ball-shaped drive handle and the slider and notch design within the hollow drive shaft allow for both long press and continuous press triggering methods, catering to the triggering needs of electronic parking brake systems in different vehicle models. Additionally, the base used for the control switch is adjustable forward and backward to accommodate different driver seating positions, ensuring smooth emergency braking activation of the electronic parking brake system in emergency situations.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] Example:

[0019] See Figure 1 - Figure 3 This embodiment relates to a built-in vehicle control switch, specifically used for parking control in a vehicle's control system. It provides stable and precise operational feedback when the vehicle is parked or undergoing temporary braking, effectively avoiding accidental activation or loss of control due to improper operation. Specifically, it includes a base 11, a parking unit 12, and a drive unit 13 for triggering the parking unit 12. The drive unit 13 includes a cylindrical housing 14, within which a drive shaft 15 is slidably disposed, and a drive handle 16 is provided on the drive shaft 15 to drive it to slide along the interior of the housing 14. The parking unit 12 is mounted and fixed to one side of the housing 14 and includes a parking button 21. The parking button 21 has a spherical structure, and the drive shaft 15 has an arc-shaped groove 22 that slides to fit the parking button 21.

[0020] Specifically, in this embodiment, when an emergency (brake failure) occurs while the driver is driving the vehicle, the drive handle 16 can be pulled or pushed to slide the drive shaft 15 along the housing 14. The arc-shaped groove 22 moves away from its original position, and the spherical parking button 21 disengages from the arc-shaped groove 22, fitting against the surface of the drive shaft 15 outside the arc-shaped groove 22, thus enabling continuous pressing of the parking button 21. This embodiment uses the push-pull drive handle 16 to trigger the electronic parking brake system, replacing the traditional pure press-type structure. This allows for easy blind operation by the driver even in sudden emergencies, avoiding the problem of brake trigger failure caused by the driver's hand slipping due to vehicle vibration or body slippage in emergency situations. It ensures that the electronic parking brake system can still be quickly and accurately activated in emergency situations, significantly improving the vehicle's emergency braking safety.

[0021] A first return spring 23 is also provided inside the housing 14. One end of the first return spring 23 is connected to the lower end of the drive shaft 15, and the other end is fixed inside the housing 14. When the driver operates the drive handle 16, the first return spring 23 can automatically and quickly pull the drive shaft 15 back to its initial position. At this time, the parking button 21 falls into the groove and is not pressed, so that the entire drive unit 13 returns to the standby state, ensuring that the parking button 21 can be pressed again through the drive unit 13 to trigger the electronic parking brake system. The return spring improves the reliability of the overall structure and ensures that the control switch can be operated continuously multiple times.

[0022] According to the manufacturer's requirements, the triggering methods of electronic parking brake systems in different vehicle models are generally divided into two categories: long press and continuous press. In this embodiment, a long press can be achieved by continuously keeping the drive handle 16 in the pulled-out state, so that the parking button 21 is away from the arc-shaped groove 22. Continuous pressing of the parking button 21 can also be achieved by repeatedly pulling the drive handle 16 (i.e., continuous press). However, the continuous press triggering method requires the driver to frequently pull the handle to perform the parking operation, which is relatively inconvenient and can easily lead to hand fatigue. Therefore, this utility model also provides a structural design suitable for continuous press triggering. Specifically, the drive handle 16 adopts a spherical structure, the drive shaft 15 adopts a hollow structure and is connected to the drive handle 16, and a slider 24 is slidably arranged inside the drive shaft 15. The arc-shaped groove 22 has a notch 25 that communicates with the inside of the drive shaft 15. Squeezing the drive handle 16 drives the slider 24 to slide downward to the notch 25 to press the parking button 21. In this embodiment, the driver applies pressure to the drive handle 16 with his palm, causing the air inside to be forced into the drive shaft 15, thereby pushing the slider 24 to move towards the notch 25, and thus pushing out the parking button 21 to achieve the pressing operation. After releasing, the slider 24 retracts from the notch 25, causing the parking button 21 to spring back. By repeatedly pressing and releasing, the parking button 21 can be continuously pressed.

[0023] In this embodiment, a second return spring 26 is provided inside the drive shaft 15. The lower end of the drive shaft 15 is closed. One end of the second return spring 26 is connected to the slider 24, and the other end is fixed to the closed end of the drive shaft 15. The second return spring 26 pulls the slider 24 back to its original position, thereby restoring the initial engagement state between the parking button 21 and the arc-shaped groove 22. At this time, the parking button 21 remains in the released state.

[0024] The parking unit 12 and the drive unit 13 are connected by a detachable structure, which facilitates the disassembly and replacement of parts during subsequent maintenance. Specifically, the parking unit 12 also includes a mounting base 31, on which the parking button 21 is disposed. A threaded mounting port 32 is provided on one side of the housing 14. The mounting base 31 is provided with an external thread structure 33 that fits into the threaded mounting port 32. The mounting base 31 is screwed into the threaded mounting port 32 so that the parking button 21 is inserted into the housing 14 and contacts the arc-shaped groove 22.

[0025] Due to differences in driving habits and seating postures, the height and angle of seat adjustments vary. To facilitate blind operation by the driver, the position of the control switch in this invention can also be adjusted forward and backward. Specifically, the base 11 includes a fixed panel 34 and a slide 35, with the slide 35 sliding relative to the fixed panel 34 in a damped slidable connection. The fixed panel 34 is integrated into the car armrest box and has a sliding groove 36. The slide 35 is slidingly connected to the sliding groove 36 in a damped slidable connection. A base plate 37 is provided below the slide 35. Elastic protrusions 38 are symmetrically arranged on the left and right sides of the slide 35, with the elastic protrusions 38 located above the base plate 37. The sliding groove 36 is located between the bottom of the protrusions and the base plate 37. The elastic protrusions 38 and the sliding groove 36 are pressed and fitted together, generating resistance when the slide 35 slides. At the same time, the elastic protrusions 38 can fix the slide 35 to the sliding groove 36 of the fixed panel 34, realizing the forward and backward adjustment of the position of the slide 35.

[0026] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
