Technical Field
[0001] This utility model relates to the field of automotive brake pedal technology, specifically to an automotive brake pedal assembly and an automotive. Background Technology
[0002] The brake pedal, used to limit a car's power and stop it, is one of the five major control components in driving, used very frequently, and how well the driver handles it directly affects driving safety. Currently, the brake pedal and pedal arm are mostly integrated, and their position cannot generally be adjusted after the vehicle leaves the factory. This makes it difficult to guarantee the operating comfort of different drivers, and in severe cases, it can even affect driving safety. In related technologies, there are pedal structures where the pedal height is adjusted by manually adjusting a nut under the pedal and then rotating the pedal. This structure can only adjust the pedal height by rotating the pedal angle, and the range of adjustment is limited. Sometimes, the comfort of the seat position must be sacrificed to adapt to the pedal position, still making it difficult to guarantee the operating comfort of different drivers; at the same time, the ease of adjustment of this pedal structure needs to be improved. Especially for driving school vehicles, where students have large differences in height and change frequently, and different students have different needs for pedal position, the pedal needs to have a wider range of position adjustment and better ease of adjustment.
[0003] Therefore, it is necessary to develop and design a new pedal assembly structure and automobile to facilitate pedal position adjustment within a wider range, thereby better ensuring the comfort of different drivers in operating the brake pedal; at the same time, it is expected to have good adjustability. Summary of the Invention
[0004] In view of this, the purpose of this utility model is to provide an automotive brake pedal assembly and an automotive vehicle, which aims to facilitate a wider range of pedal position adjustment, thereby better ensuring the comfort of different drivers in operating the brake pedal.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automobile brake pedal assembly, comprising: a first pedal arm having a slide rail section thereon; a slide block, the slide block being slidably disposed on the slide rail section in a driveable and lockable manner; a second pedal arm, the second pedal arm being disposed on the slide block in a driveable and lockable manner; and a pedal fixedly disposed at the rear end of the second pedal arm.
[0006] Furthermore, an electric push rod for driving the slide to slide is provided between the slide and the first pedal arm. A rotary motor with a motor shaft locking function is fixedly installed on the slide. The output shaft of the rotary motor is connected to the second pedal arm to drive the swing of the second pedal arm.
[0007] Furthermore, the first pedal arm is provided with a receiving groove for accommodating an electric push rod, which is installed in the receiving groove.
[0008] Furthermore, the front end of the electric push rod is hinged to the front side wall of the receiving groove, and the rear end of the electric push rod is hinged to the slide block.
[0009] Furthermore, the slide rail section includes two sets of slide rail plates integrally formed with the first pedal arm and arranged relatively parallel to each other. The slide block is slidably sleeved on the two sets of slide rail plates, and the second pedal arm is located between the two sets of slide rail plates.
[0010] Furthermore, the rotary motor is fixedly installed on the outer side of one of the slide rails, and the motor shaft of the rotary motor is arranged along the transverse direction of the vehicle and passes through the two slide rails respectively. The corresponding end of the second pedal arm is synchronously rotated and set on the motor shaft of the rotary motor. The slide rail is provided with long slots arranged along the sliding direction of the slide block to avoid the motor shaft of the rotary motor.
[0011] Furthermore, it also includes a linkage reinforcement frame that can be linked with the swing of the second pedal arm. The linkage reinforcement frame includes a first link and a second link. The two ends of the first link are respectively hinged to the first pedal arm and the second link. The end of the second link away from the first link is hinged to the middle section of the second pedal arm.
[0012] Furthermore, a damping rubber ring is provided at the hinge joint of the first link and the second link.
[0013] Furthermore, the pedal and the movable end of the second pedal arm are fixedly connected in a detachable manner.
[0014] A vehicle is also provided, including the vehicle brake pedal assembly as described.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] The automotive brake pedal assembly provided by this utility model facilitates a wider range of pedal position adjustments, thereby better ensuring the comfort needs of different drivers for brake pedal operation. Specifically, in this automotive brake pedal assembly structure, the second pedal arm can not only adjust its swing angle but also move with the slide seat to adjust the overall length of the pedal arm. This allows for a wider range of position adjustments within the longitudinal section of the vehicle, further ensuring the comfort needs of different drivers for brake pedal operation. Furthermore, due to the relatively large adjustment range of the pedal position, in practical use, the seat can be adjusted to a position suitable for the driver's field of vision first, and then the pedal position can be adjusted to a position suitable for the driver's operation. This eliminates the need to sacrifice seat comfort to adapt to the pedal position, improving driving comfort and thus driving safety. Of course, the automotive brake pedal assembly in this structure also has the advantage of simple structure. The automotive brake pedal assembly provided by this utility model better ensures the comfort needs of different drivers for brake pedal operation.

Detailed Implementation
[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent a sequential execution order, but are merely for the convenience of description. In the following text, "lateral" unless otherwise specified, refers to the lateral direction of the vehicle body, that is, the width direction of the vehicle. In the following text, the front-rear direction of the vehicle refers to the length direction of the vehicle, with the front side of the vehicle being the front and the rear side being the rear.
[0022] Please see Figure 1-2 This embodiment discloses an automotive brake pedal assembly, including a first pedal arm 1, a slide block 2, a second pedal arm 3, and a pedal 4. The first pedal arm 1 has a slide rail section 101; the slide block 2 is slidably mounted on the slide rail section 101 in a driveable and lockable manner; the second pedal arm 3 is mounted on the slide block 2 in a driveable and lockable manner; and the pedal 4 is fixed to the rear end of the second pedal arm 3. It is understood that in this automotive brake pedal assembly structure, the first pedal arm 1 and the second pedal arm 3 together constitute a complete brake pedal arm. It is also understood that the second pedal arm 3 swings in a vertical plane in the longitudinal direction of the vehicle. The brake pedal arm is used to transmit the force of the driver pressing the brake pedal 4 to the braking mechanism, thereby achieving braking control of the vehicle. By setting a slide rail section 101 on the first pedal arm 1, the sliding seat 2 is slidably mounted on the slide rail section 101, ensuring the simplicity of the overall structure and reducing manufacturing costs. The second pedal arm 3 can move along with the slide seat 2, thereby realizing the adjustment of the overall length of the brake pedal arm. The swinging of the second pedal arm 3 can realize the adjustment of the height position of the pedal 4. Theoretically, the driving form of the slide seat 2 and the second pedal arm 3 can be of various forms, such as manual drive adjustment or electric drive adjustment, etc., which is not limited here.
[0023] The aforementioned automotive brake pedal assembly allows for greater adjustment of the pedal's position, thus better ensuring the comfort needs of different drivers for operating the brake pedal 4. Specifically, in this automotive brake pedal assembly structure, the second pedal arm 3 can not only adjust its swing angle but also move with the slide 2 to adjust the overall length of the pedal arm. This facilitates a greater range of adjustment within the longitudinal section of the vehicle (longitudinal refers to the length direction of the vehicle), further ensuring the comfort needs of different drivers for operating the brake pedal 4. Furthermore, because the position adjustment range of the pedal 4 is relatively large, in practical use, the seat can be adjusted to a position suitable for the driver's field of vision first, and then the pedal position can be adjusted to a position suitable for the driver's operation. This eliminates the need to sacrifice seat comfort to accommodate the pedal 4 position, improving driving comfort and consequently, driving safety. Of course, the automotive brake pedal assembly in this structure also has the advantage of simple structure.
[0024] In this embodiment, an electric push rod 5 for driving the sliding of the slide 2 is provided between the slide 2 and the first pedal arm 1. A rotary motor 6 with a motor shaft locking function is fixedly installed on the slide 2. The output shaft of the rotary motor 6 is connected to the second pedal arm 3 to drive the swing of the second pedal arm 3. In this structural design, the sliding of the slide 2 is driven by the electric push rod 5, and the swing of the second pedal arm 3 is driven by the rotary motor 6. Both can be electrically controlled. In actual use, the pedal position can be adjusted by means of physical button control, which is convenient and especially suitable for applications with high pedal position adjustment frequency, such as driving school vehicles. The electric push rod 5 driving form is conducive to bearing large loads and has low maintenance costs; at the same time, it does not require complex complete system support, which is conducive to space layout and installation; at the same time, the electric push rod 5 can achieve precise locking of the position of the slide 2, so that the slide 2 is stably locked in the set position, and the reliability is good. More specifically, the rotary motor 6 here is a servo motor, which can achieve precise control of the swing angle of the second pedal arm 3. Of course, it is understandable that servo motors can achieve motor shaft locking through mechanical locking systems and electromagnetic locking systems, which are conventional structures for existing servo motors and will not be elaborated upon here. This allows the second pedal arm 3 to be stably locked at the set angle position.
[0025] In this embodiment, the first pedal arm 1 is provided with a receiving groove 102 for accommodating the electric push rod 5, and the electric push rod 5 is installed in the receiving groove 102. Specifically, the receiving groove 102 is an elongated slot with its opening facing downwards. By arranging the electric push rod 5 in the receiving groove 102, it is beneficial to ensure the compactness of the overall structure, thereby reducing the space occupied near the pedal position and facilitating the arrangement and installation of the overall structure.
[0026] In this embodiment, the front end of the electric push rod 5 is hinged to the front side wall of the receiving groove 102, and the rear end of the electric push rod 5 is hinged to the slide block 2. It is understood that "front end" refers to the front side of the vehicle, and "rear end" refers to the rear side of the vehicle. The hinged installation at both ends of the electric push rod 5 facilitates its arrangement and installation, making it suitable for situations where the first pedal arm 1 has a certain degree of curvature. This reduces the risk of jamming and improves the smoothness of the sliding of the slide block 2.
[0027] In this embodiment, the slide rail section 101 includes two sets of slide rail plates 101a integrally formed with the first pedal arm 1 and arranged relatively parallel to each other. The slide seat 2 is slidably sleeved on the two sets of slide rail plates 101a. The second pedal arm 3 is located between the two sets of slide rail plates 101a. The second pedal arm 3 can swing vertically between the two sets of slide rail plates 101a, thus ensuring the stability of the second pedal arm 3 swinging in the vertical plane in the front-rear direction of the vehicle. In this structural design, the overall structure of the pedal arm has good structural strength, and the two sets of slide rail plates 101a can form a lateral protection for the second pedal arm 3, ensuring the reliability of the installation of the second pedal arm 3.
[0028] In this embodiment, the rotary motor 6 is fixedly installed on the outer side of one set of slide rails 101a in the transverse direction. The motor shaft of the rotary motor 6 is arranged in the transverse direction of the vehicle and passes through both sets of slide rails 101a. The corresponding end of the second pedal arm 3 is synchronously rotated and mounted on the motor shaft of the rotary motor 6. The slide rail 101a is provided with a long slot 101a1 arranged in the sliding direction of the slide block 2 to avoid the motor shaft of the rotary motor 6. Specifically, the front end of the second pedal arm 3 can be connected to the motor shaft of the rotary motor 6 through a spline, so that the rotary motor 6 drives the second pedal arm 3 to swing. In this structural design, the arrangement of the rotary motor 6 is reasonable and conducive to the spatial arrangement near the pedal position; the installation reliability of the rotary motor 6 is high, which helps to ensure the service life of the overall structure.
[0029] In this embodiment, a linkage reinforcement frame 7 is also included, which can be linked with the swing of the second pedal arm 3. The linkage reinforcement frame 7 includes a first link 701 and a second link 702. The two ends of the first link 701 are respectively hinged to the first pedal arm 1 and the second link 702. The end of the second link 702 away from the first link 701 is hinged to the middle section of the second pedal arm 3. It can be understood that, for the convenience of spatial arrangement, the linkage reinforcement frame 7 is set on the upper part of the second pedal arm 3 and the first pedal arm 1. By setting the linkage reinforcement frame 7, the load-bearing capacity of the second pedal arm 3 can be improved, and the overall structural durability and reliability can be improved. Among them, the second link 702 is hinged to the middle section of the second pedal arm 3, which is equivalent to reducing the cantilever length of the second pedal arm 3, thereby reducing the load on the connection between the second pedal arm 3 and the slide 2 and improving the structural reliability.
[0030] In this embodiment, a damping rubber ring 703 is provided at the hinge joint of the first link 701 and the second link 702. Specifically, the first link 701 and the second link 702 are hinged together by a hinge shaft, and the damping rubber ring 703 is sleeved on the hinge shaft. The damping rubber ring, with its softness and malleability, effectively absorbs and reduces vibrations and impacts on the pedal arm during use, reducing shaking and thus improving the comfort of pedal use.
[0031] In this embodiment, the pedal 4 and the movable end of the second pedal arm 3 are fixedly connected in a detachable manner. Specifically, the back of the pedal 4 is provided with a slot positioning hole, which is fitted onto the rear end of the second pedal arm 3. Then, the pedal 4 and the second pedal arm 3 are fixed by bolts. By adopting a detachable connection method, it is convenient to replace and repair the pedal.
[0032] This embodiment also discloses a car, including the car brake pedal assembly as described above, which can better ensure the comfort of different drivers in operating the brake pedal.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
