A concealed pedal

Abstract

This invention relates to the field of automotive brake pedal technology, specifically to a concealed pedal, comprising a brake bracket, a first pin, a brake swing arm, a booster pushrod ball, and a drive component. The first groove is arc-shaped, and its center coincides with the center of the booster pushrod ball. In automatic / assisted driving mode, the output end of the drive component extends, driving the first pin from a first position to a second position. At this time, the brake swing arm rotates around the booster pushrod ball, causing the brake swing arm and its pedal surface to retract from the driver's foot operating position towards the front bulkhead, providing more foot space for the driver's right foot and improving driving comfort.

Description

Technical Field

[0001] This invention relates to the field of automotive brake pedal technology, and more particularly to a concealed pedal. Background Technology

[0002] The brake pedal is the core human-machine interface component for drivers to decelerate and brake. In traditional cars, the brake pedal is typically fixedly connected to the master cylinder or brake booster via a rigid linkage mechanism or lever system. The pedal assembly is rigidly mounted on the front bulkhead or floor, and the position of the pedal surface (i.e., the foot area) relative to the driver's seat remains constant. This fixed arrangement ensures the directness and reliability of braking force transmission, but it also brings a long-standing drawback: it permanently occupies the space in front of the driver's right foot, restricting the freedom of movement of the right foot when not braking. During long drives, especially cruising or following other vehicles in congested traffic, the driver's right foot cannot be effectively relaxed, easily leading to fatigue and affecting driving comfort.

[0003] With the rapid development of automotive intelligent technology, Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD) functions are becoming increasingly common. In autonomous driving or advanced driver assistance modes, the vehicle's system can take over longitudinal (acceleration / deceleration) control in specific scenarios, at which point the driver does not need to continuously operate the brake pedal.

[0004] However, the traditional fixed brake pedal remains in place, and its physical obstruction becomes particularly prominent in autonomous driving mode. Drivers expect to be able to completely remove their right foot, stretch it out, and even make small movements to alleviate fatigue when the system takes over the vehicle, but the fixed pedal constitutes an obstacle, affecting the comfort enhancement that autonomous driving mode should bring. Summary of the Invention

[0005] The purpose of this invention is to provide a hidden pedal that solves the problem of traditional fixed brake pedals restricting the driver's foot movement space in autonomous driving mode.

[0006] To achieve the above objectives, the present invention provides a concealed pedal, including a brake bracket, a first pin, a brake swing arm, a booster push rod ball, and a drive component. The brake bracket is mounted on a vehicle and has a first groove that extends through the brake bracket. The first pin passes through the first groove. The brake swing arm is fixedly connected to the first pin and is mounted on the first pin. The booster push rod ball is fixedly connected to the brake swing arm and is connected to the push rod end of the vehicle brake booster. The drive component is used to drive the first pin to slide within the first groove. The first groove is arc-shaped, and the center of the first groove coincides with the center of the ball of the booster push rod.

[0007] The driving component includes a second pin, a brake swing arm connecting rod, and a telescopic component. The second pin is slidably connected to the brake bracket and is disposed on the brake bracket. The brake swing arm connecting rod is rotatably connected to the first pin and connected to the second pin, and is disposed on the brake bracket. The telescopic component is disposed on the brake bracket and is used to drive the second pin to move, thereby driving the first pin to slide along the first groove through the brake swing arm connecting rod.

[0008] The brake bracket has a second groove that extends through the brake bracket, and the second pin passes through the second groove.

[0009] The brake swing arm connecting rod has a third sliding groove, which passes through the brake swing arm connecting rod, and the second pin passes through the third sliding groove.

[0010] The telescopic component includes an electric cylinder and a pusher seat. The electric cylinder is connected to the brake bracket and is mounted on the brake bracket. The pusher seat is connected to the second pin and is connected to the output end of the electric cylinder.

[0011] The push seat has a fourth sliding groove that extends through the push seat, and the second pin passes through the fourth sliding groove.

[0012] The concealed pedal further includes a first anti-reverse component, which is fixedly connected to the first pin and located at the end of the first pin.

[0013] The driving component further includes a second anti-reverse component, which is fixedly connected to the second pin and located at one end of the second pin.

[0014] In a concealed pedal of the present invention, in manual driving mode, the output end of the drive component retracts, driving the first pin to move along the first slide groove to a first position. This causes the brake swing arm, fixedly connected to the first pin, to rotate around the center of the booster push rod ball as its rotation center, thereby resetting the brake swing arm and its pedal surface from a retracted position near the front panel of the vehicle to an operable position near the driver's foot. When the driver presses the brake swing arm, the brake swing arm rotates around the first pin as its center, thereby causing the center of the booster push rod ball to rotate, transmitting the pedal force applied by the driver to the push rod of the vehicle's brake booster, thus performing a braking operation. In automatic / assisted driving mode, the output end of the drive component extends, driving the first pin to move from the first position to the second position. At this time, the brake swing arm rotates around the center of the booster push rod ball as its center, thereby retracting the brake swing arm and its pedal surface from the operable position near the driver's foot towards the front panel of the vehicle.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] First embodiment: Please see Figures 1 to 5 ,in Figure 1 This is a diagram showing the retractable pedal in the extended position. Figure 2 This is a diagram showing the concealed pedals in their retracted state. Figure 3 This is a schematic diagram of the first chute.

[0025] This invention provides a concealed pedal, comprising a brake bracket 101, a first pin 102, a brake swing arm 103, a booster push rod ball center 104, and a drive component 105. The drive component 105 includes a second pin 106, a brake swing arm connecting rod 107, and a telescopic component 108. The brake bracket 101 has a second slide groove 109, the brake swing arm connecting rod 107 has a third slide groove 110, and the telescopic component 108 includes an electric cylinder 111 and a push seat 112. The push seat 112 has a fourth slide groove 113. The drive component 105 drives the second pin 106 to move to both ends of the first slide groove 114, thereby causing the brake swing arm 103 to rotate around the booster push rod ball center 104, realizing the retraction of the brake pedal in automatic / assisted driving mode and the reset movement in manual driving mode. It is understood that the aforementioned solution can be used to retract the car brake pedal and improve driving comfort.

[0026] In this specific embodiment, the brake bracket 101 is installed on the vehicle. The brake bracket 101 has a first groove 114 that extends through the brake bracket 101. The first pin 102 passes through the first groove 114. The brake swing arm 103 is fixedly connected to the first pin 102 and is disposed on the first pin 102. The booster push rod ball center 104 is fixedly connected to the brake swing arm 103 and is connected to the push rod end of the vehicle brake booster. The driving member 105 is used to drive the first pin 102 to slide within the first groove 114. The first groove 114 is arc-shaped, and the center of the first groove 114 coincides with the position of the booster push rod ball center 104.

[0027] The positions of the two ends of the first slide groove 114 are defined as the first position 115 and the second position 116, respectively. In manual driving mode, the output end of the drive component 105 retracts, driving the first pin 102 to move along the first slide groove 114. The first pin 102 is then moved along the first slide groove 114 to the first position 115, causing the brake swing arm 103, which is fixedly connected to the first pin 102, to rotate around the booster push rod ball center 104 as the rotation center. This resets the brake swing arm 103 and its pedal surface from the storage position near the front panel of the vehicle to the operable position of the driver's foot. When the driver steps on the brake swing arm 103, the brake swing arm 103 rotates around the first pin 102 as the center, thereby driving the booster push rod ball center 104 to rotate and transmitting the pedal force applied by the driver to the push rod of the car brake booster, thus performing the braking operation.

[0028] When the vehicle is in automatic / assisted driving mode, the output end of the drive component 105 extends, thereby driving the first pin 102 to move from the first position 115 to the second position 116. At this time, the brake swing arm 103 rotates around the booster push rod ball center 104, thereby causing the brake swing arm 103 and its pedal surface to retract from the operable position of the driver's foot towards the front panel of the vehicle.

[0029] Since the brake swing arm 103 rotates around the fixed booster push rod ball center 104 during the entire movement of the first pin 102 from the first position 115 to the second position 116, and the position of the booster push rod ball center 104 itself is fixed relative to the brake bracket 101 and the push rod end of the car brake booster, this rotational movement will not generate any thrust or pull force on the push rod of the car brake booster, thereby ensuring that the brake system is not accidentally driven during the pedal retraction or reset process.

[0030] The second pin 106 is slidably connected to the brake bracket 101 and is disposed on the brake bracket 101; the brake swing arm connecting rod 107 is rotatably connected to the first pin 102 and connected to the second pin 106, and is disposed on the brake bracket 101; the telescopic member 108 is disposed on the brake bracket 101, and the telescopic member 108 is used to drive the second pin 106 to move, thereby driving the first pin 102 to slide along the first slide groove 114 through the brake swing arm connecting rod 107.

[0031] Secondly, the second groove 109 passes through the brake bracket 101, and the second pin 106 passes through the second groove 109.

[0032] The second pin 106 is located on the side of the brake swing arm link 107 away from the first pin 102. The second pin 106 is driven to move along the second slide groove 109 by the telescopic component 108, thereby driving the brake swing arm link 107 to move. The movement of the brake swing arm link 107 forces the first pin 102 connected to it to slide along the first slide groove 114.

[0033] Meanwhile, the third slide groove 110 passes through the brake swing arm connecting rod 107, and the second pin 106 passes through the third slide groove 110; the third slide groove 110 allows the second pin 106 to slide relative to it, avoiding motion interference between the second pin 106 and the brake swing arm connecting rod 107 when the second pin 106 moves along the second slide groove 109.

[0034] In addition, the electric cylinder 111 is connected to the brake bracket 101 and is mounted on the brake bracket 101; the push seat 112 is connected to the second pin 106 and is connected to the output end of the electric cylinder 111; the operation of the electric cylinder 111 drives the push seat 112 to move, and the push seat 112 drives the second pin 106 to move along the second slide groove 109.

[0035] Finally, the fourth slide groove 113 passes through the push seat 112, and the second pin 106 passes through the fourth slide groove 113; through the fourth slide groove 113, motion interference between the push seat 112 and the second pin 106 is avoided.

[0036] When using the concealed pedal of this embodiment, when the vehicle is in automatic or assisted driving mode, the electric cylinder 111 receives a control signal and starts, its output end extends, pushing the push seat 112 to move in a straight line; the push seat 112 drives the second pin 106 through the fourth slide groove 113 on it, causing the second pin 106 to slide along the second slide groove 109 on the brake bracket 101; the sliding of the second pin 106, through its cooperation with the third slide groove 110 on the brake swing arm linkage 107, drives the brake swing arm linkage 107 to produce a specific movement; the brake swing arm linkage 107 then drives the first pin 102 to move along the brake... The first arc-shaped groove 114 on the moving bracket 101 slides from the first position 115 corresponding to the manual driving position to the second position 116 corresponding to the storage position. Since the center of the first groove 114 coincides with the center of the booster push rod ball 104, the sliding of the first pin 102 is converted into the rotational movement of the brake swing arm 103 around the fixed booster push rod ball 104 toward the front panel of the vehicle, thereby storing and hiding the pedal surface and freeing up space for the driver's feet. Because the rotation center is fixed and coincides with the connection point at the end of the brake booster push rod, this process will not cause any action to the braking system, ensuring safety. When the vehicle switches back to manual driving mode, the output end of the electric cylinder 111 retracts, the driving process reverses, and finally the first pin 102 slides back to the first position 115. The brake swing arm 103 rotates in the opposite direction around the same center, resetting the pedal surface to the initial position that is easy to operate. After resetting, when the driver performs the braking operation, the pedal force drives the brake swing arm 103 to rotate around the center ball 104 of the booster push rod and pushes the booster push rod, realizing the direct and reliable transmission of braking force.

[0037] Second embodiment: Based on the first embodiment, please refer to Figure 6 , Figure 6 This is a schematic diagram of the installation structure of the first and second anti-reverse components in the second embodiment. The hidden pedal in this embodiment also includes the first anti-reverse component 201, and the drive component 105 also includes the second anti-reverse component 202.

[0038] In this specific embodiment, the first anti-reverse member 201 is fixedly connected to the first pin 102 and is located at the end of the first pin 102; the first anti-reverse member 201 is used to constrain the axial position of the first pin 102 and prevent it from axially moving or coming out of the first slide groove 114 when it slides in the first slide groove 114.

[0039] The second anti-reverse member 202 is fixedly connected to the second pin 106 and is located at one end of the second pin 106. The second anti-reverse member 202 is used to constrain the axial position of the second pin 106 and prevent it from axially moving or coming out of the mating system of the second slide groove 109, the third slide groove 110 and the fourth slide groove 113 when it slides in the second slide groove 109.
