Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and more particularly to a brake pedal assembly and a vehicle. Background Art

[0002] In some related technologies, due to the significant differences in driver size, proper vehicle operation requires adjustments to the position of internal vehicle components (e.g., seat adjustment). Furthermore, the driver's ergonomic posture also varies in different driving modes. However, since the pedal assembly has a fixed lever ratio based on braking performance, pedal feel, and booster parameters, the pedal assembly's position is fixed, impacting the varying needs of drivers.

[0003] In other related technologies, there are three ways to adjust the position of the pedal assembly:

[0004] (1) Non-constant lever ratio adjustment. The non-constant lever ratio adjustment will change the lever ratio of the pedal assembly, which will cause the pedal feel of the pedal assembly to change, affecting the driver's driving experience. If a step-by-step adjustment method is used, the adjustment effect will be poor and the development difficulty and manpower will be increased.

[0005] (2) Constant lever ratio pedal arm type. The constant lever ratio pedal arm type requires a larger layout space and cannot achieve smooth conversion between the accelerator pedal and the brake assembly.

[0006] (3) Pedal arm telescopic type and multi-link type pedal arm adjustment. The structures of the pedal arm telescopic type and multi-link type pedal arm adjustment are complex and occupy a large volume. Utility Model Content

[0042] The brake pedal assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] Reference Figure 1-Figure 4 As shown, the brake pedal assembly 100 according to an embodiment of the present invention is used in a vehicle, and the brake pedal assembly 100 can be used to control the braking of the vehicle and ensure driving safety. The brake pedal assembly 100 can include: an adjustment component 20 and a pedal component 30.

[0044] Specifically, the adjustment assembly 20 includes an adjustment body 21 and a first rotating shaft 22. The first rotating shaft 22 is connected to the adjustment body 21. The upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22. The first rotating shaft 22 can form the working rotation axis of the brake assembly. When the driver steps on the pedal assembly 30, the pedal assembly 30 rotates about the first rotating shaft 22, thereby achieving braking control of the vehicle, such as slowing down and stopping the vehicle.

[0045] In addition, if Figure 1-Figure 3 As shown, the adjustment assembly 20 further includes a pedal bracket 10 and a second rotating shaft 23. The second rotating shaft 23 is connected to the adjustment body 21. The second rotating shaft 23 is located below the first rotating shaft 22 and is rotatably connected to the pedal bracket 10. As a result, the adjustment body 21 can rotate relative to the pedal bracket 10 via the second rotating shaft 23, allowing the adjustment body 21 to drive the pedal assembly 30 to move. This allows the pedal assembly 30 to be adjusted to suit different drivers' pedaling habits and legroom requirements, ensuring the comfort of the pedal assembly 30 and improving driving comfort and safety.

[0046] Compared with the coaxial adjustment of the pedal assembly 30 by the first rotating shaft 22 and the second rotating shaft 23, the first rotating shaft 22 and the second rotating shaft 23 of the utility model are not coaxial, which avoids the problem of uneven conversion of the throttle pedal and the pedal assembly 30 after adjustment caused by the coaxiality of the first rotating shaft 22 and the second rotating shaft 23, and can meet the adjustment of the pedal assembly 30 with a constant lever ratio, reducing the layout space. At the same time, there is no need to make major changes to the pedal assembly 30, that is, the pedal assembly 30 can adopt an ordinary size pedal assembly 30, which can reduce the occupied volume and is conducive to platformization.

[0047] According to the brake pedal assembly 100 of the embodiment of the present invention, the first rotating shaft 22 and the second rotating shaft 23 are both connected to the adjustment body 21. The second rotating shaft 23 is located below the first rotating shaft 22. The second rotating shaft 23 is rotatably connected to the pedal bracket 10, and the upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22, so that the pedal assembly 30 can be adjusted through the adjustment body 21 to adapt to the pedaling habits and leg space requirements of different drivers, ensure the comfort of the pedal assembly 30, and avoid the problem of uneven conversion of the accelerator pedal and the pedal assembly 30 after adjustment due to the coaxiality of the first rotating shaft 22 and the second rotating shaft 23, so as to meet the adjustment of the pedal assembly 30 with a constant lever ratio, while occupying a small volume, reducing the layout space, and being conducive to platformization.

[0048] In some embodiments of the present invention, Figure 1 As shown, the brake pedal assembly 100 also includes a driving mechanism 40, which is connected to the pedal bracket 10. The driving mechanism 40 can drive the adjustment component 20 to rotate around the second rotating shaft 23, and can realize the automatic adjustment function of the brake pedal assembly 100, making the adjustment more convenient, which is beneficial to improving the convenience of driving and realizing intelligent control.

[0049] According to some embodiments of the present invention, Figure 1 As shown, at least a portion of the second rotating shaft 23 is formed into a worm gear. The drive mechanism 40 includes a drive motor 41 and a worm 42. The drive motor 41 is connected to the pedal bracket 10 to secure the drive motor 41. The worm 42 is connected to the output shaft of the drive motor 41, and the worm 42 cooperates with the worm wheel. As a result, the drive motor 41 can drive the worm 42 to rotate via the output shaft, allowing the worm gear 42 to cooperate to achieve stepless adjustment, facilitating meeting the driver's diverse driving needs and ensuring smoother and more precise adjustment. The worm gear 42 also has a self-locking feature that prevents the pedal assembly 30 from rotating about the second rotating shaft 23 due to other forces. This improves the stability and safety of the brake pedal assembly 100, while ensuring the compact structure of the brake pedal assembly 100 and reducing space requirements.

[0050] In some embodiments of the present invention, Figure 1-Figure 3As shown, the adjustment body 21 includes a first adjustment plate 211 and a second adjustment plate 212. The first adjustment plate 211 and the second adjustment plate 212 are arranged along the thickness direction of the first adjustment plate 211 (eg Figure 1 The pedal assembly 30 is located between the first adjustment plate 211 and the second adjustment plate 212. The length direction of the first rotating shaft 22 (for example Figure 1 The two ends of the adjusting body 21 (in the left and right directions shown in the figure) are respectively connected to the first adjustment plate 211 and the second adjustment plate 212, and the second rotating shaft 23 is connected to the first adjustment plate 211, ensuring that the first rotating shaft 22 and the second rotating shaft 23 are reliably connected to the adjusting body 21, thereby providing stable support for the pedal assembly 30, ensuring the stability and reliability of the pedal assembly 30 during the adjustment process, and the structure of the adjusting body 21 is simple, easy to process and manufacture, and at the same time can ensure a compact structure, which is conducive to achieving a lightweight design.

[0051] According to some embodiments of the present invention, Figure 1 As shown, the adjustment assembly 20 further includes a third shaft 24, which is located on a side of the second adjustment plate 212 away from the pedal assembly 30. The length direction of the third shaft 24 (eg Figure 1 One end of the third rotating shaft 24 (in the left and right directions shown in the figure) is connected to the second adjusting plate 212, and the other end of the third rotating shaft 24 in the length direction is rotatably connected to the pedal bracket 10. The third rotating shaft 24 is coaxial with the second rotating shaft 23. The third rotating shaft 24 can be connected to the second adjusting plate 212 and the pedal bracket 10, which adds a support point to the adjusting assembly 20 and ensures that the second adjusting plate 212 is fixed reliably, thereby further ensuring that the adjusting body 21 is fixed reliably, and improving the stability and carrying capacity of the adjusting assembly 20.

[0052] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the pedal assembly 30 is provided with a limiting shaft 31, and the adjustment body 21 is provided with an arcuate groove 213 centered about the axis of the first rotating shaft 22. The limiting shaft 31 extends into the arcuate groove 213. Thus, when the brake pedal assembly 100 is braking, that is, when the pedal assembly 30 rotates about the first rotating shaft 22, the limiting shaft 31 cooperates with the arcuate groove 213, allowing the adjustment body 21 to limit the rotation of the pedal assembly 30, preventing the pedal assembly 30 from excessive rotation or deviation from the predetermined position, thereby improving the stability and reliability of the brake pedal assembly 100.

[0053] In some embodiments, the adjustment body 21 includes a first adjustment plate 211 and a second adjustment plate 212, such as Figure 1 As shown, the width direction (eg Figure 1A limiting shaft 31 is provided on both sides of the first adjustment plate 211 and the second adjustment plate 212, and an arc groove 213 with the axis of the first rotating shaft 22 as the center of the circle is provided. The two limiting shafts 31 respectively extend into the arc groove 213 on the same side. Through the cooperation of the two limiting shafts 31 and the two arc grooves 213, the two sides of the width direction of the pedal assembly 30 can be limited to prevent the pedal assembly 30 from tilting during movement, thereby ensuring the stability and reliability of the brake pedal assembly 100.

[0054] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the brake pedal assembly 100 further includes a booster, which includes a cage 51 and a booster rod. One end of the booster rod is rotatably connected to the cage 51, and the cage 51 is connected to the pedal assembly 30. Therefore, when the brake pedal assembly 100 is braking, the pedal assembly 30 is stepped on, the adjustment assembly 20 remains stationary, and the pedal assembly 30 rotates about the first rotation axis 22 (for example, counterclockwise). The pedal assembly 30 and the cage 51 press against each other and push the cage 51, so that the cage 51 pushes the booster rod to move, achieving normal operation of the brake pedal assembly 100. The booster can provide additional assistance, making the braking process easier and faster, and effectively reducing the driver's physical exertion when stepping on the brake assembly. When the pedal assembly 30 is released, the booster rod transmits force to the cage 51, causing the pedal assembly 30 to rotate in the opposite direction (for example, clockwise) about the first rotation axis 22 under the driving action of the cage 51, thereby resetting the pedal assembly 30.

[0055] In addition, if Figure 1-Figure 4 As shown, the ball cage 51 is rotatably connected to the pedal assembly 30, and the ball cage 51 is located below the first rotating shaft 22. Therefore, when the pedal assembly 30 is adjusted, that is, when the adjustment body 21 rotates relative to the pedal bracket 10 through the second rotating shaft 23, the pedal assembly 30 can rotate relative to the ball cage 51, thereby ensuring that the ball cage 51 does not change position with the adjustment of the pedal assembly 30, ensuring that the power-assisting rod remains in a normal swing position, and meeting the swing position requirements required by the power-assisting rod.

[0056] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the pedal assembly 30 is provided with a slide groove 32, the inner wall of the slide groove 32 is an arc-shaped surface, the outer peripheral wall of the ball cage 51 is in contact with the inner wall of the slide groove 32, and the ball cage 51 is rotatable relative to the inner wall of the slide groove 32, which can realize the rotational connection between the ball cage 51 and the pedal assembly 30, facilitates the rotation of the pedal assembly 30 relative to the ball cage 51, and makes the pedal assembly 30 rotate smoothly relative to the ball cage 51, and has a simple structure, which is convenient for processing and manufacturing, and helps to reduce production costs.

[0057] According to some embodiments of the present invention, Figure 1 and Figure 4As shown, the pedal assembly 30 includes a pedal arm 301 and a pedal pad 302. The upper end of the pedal arm 301 is rotatably connected to the first rotating shaft 22, and the pedal pad 302 is connected to the lower end of the pedal arm 301. The pedal pad 302 is the direct contact surface between the driver and the pedal arm 301. The pedal pad 302 can provide a comfortable pedaling feeling and good friction, and the pedal pad 302 can be connected to the adjustment assembly 20 through the pedal arm 301, which is convenient for adjusting the position of the pedal pad 302. At the same time, the force of the driver stepping on the pedal pad 302 can be transmitted to the pedal arm 301, and the braking control of the vehicle can be achieved through the pedal arm 301.

[0058] Furthermore, a pressure sensor is provided on the pedal pad 302. This sensor can detect the presence and magnitude of pressure on the pedal pad 302, providing accurate feedback and enabling intelligent operation. For example, when adjusting the pedal assembly 30, the pressure sensor can detect whether the driver is stepping on the pedal pad 302, providing a driver alert and preventing the pedal assembly 30 from jamming the driver's foot, thereby improving the safety level of the brake pedal assembly 100.

[0059] According to the control method of the brake pedal assembly 100 according to the embodiment of the present invention, the brake pedal assembly 100 is the brake pedal assembly 100 according to the embodiment of the present invention.

[0060] like Figure 5 and Figure 7 As shown, the control method includes:

[0061] Make sure the vehicle is powered on;

[0062] Obtaining angle parameters of the pedal assembly 30 to facilitate subsequent determination of whether the pedal assembly 30 is within a comfortable angle range for the driver;

[0063] Determining that the angle of the pedal assembly 30 is at an uncomfortable angle, for example, the uncomfortable angle may be that the angle of the pedal assembly 30 cannot meet the requirements of a comfortable operating position of the driver or the driving mode selected in the control system of the vehicle is different from the current angle of the pedal assembly 30;

[0064] The adjustment assembly 20 is controlled to rotate about the second rotation axis 23 until the angle of the pedal assembly 30 reaches a comfortable target angle parameter. For example, the adjustment assembly 20 is driven to rotate about the second rotation axis 23 by the drive motor 41. Thus, before the driver starts driving, the pedal assembly 30 can be adjusted to accommodate different pedaling habits and legroom requirements, ensuring pedaling comfort of the pedal assembly 30 and improving driving comfort and safety.

[0065] In some embodiments, when the drive motor 41 drives the adjustment assembly 20 to rotate around the second rotation axis 23, the target angle parameter can be the rotation angle parameter of the drive motor 41 set in different driving modes, or the target angle parameter can be a dedicated rotation angle parameter of the drive motor 41 set by an individual. The angle of the pedal assembly 30 is at a non-comfortable angle because the current rotation angle of the drive motor 41 is different from the target angle parameter. By controlling the rotation angle of the drive motor 41, the angle of the pedal assembly 30 can reach the target angle parameter, making the adjustment simpler and more convenient, and facilitating stepless adjustment.

[0066] Since the brake pedal assembly 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the control method of the brake pedal assembly 100 according to the embodiment of the present invention is that the first rotating shaft 22 and the second rotating shaft 23 are both connected to the adjustment body 21, the second rotating shaft 23 is located below the first rotating shaft 22, the second rotating shaft 23 is rotatably connected to the pedal bracket 10, and the upper end of the pedal assembly 30 is rotatably connected to the first rotating shaft 22, so that the pedal assembly 30 can be adjusted through the adjustment body 21 to adapt to the pedaling habits and leg space requirements of different drivers, ensure the comfort of the pedal assembly 30, and avoid the problem of uneven conversion of the accelerator pedal and the pedal assembly 30 after adjustment due to the coaxiality of the first rotating shaft 22 and the second rotating shaft 23, so as to meet the adjustment of the pedal assembly 30 with a constant lever ratio, while occupying a small volume, reducing the layout space, and being conducive to platformization.

[0067] In some embodiments of the present invention, Figure 6 As shown, the control method of the brake pedal assembly 100 further includes:

[0068] Make sure the vehicle is powered off;

[0069] The adjustment assembly 20 is controlled to rotate about the second rotation axis 23 to move the lower end of the pedal assembly 30 downward until the pedal assembly 30 reaches the lower limit position. For example, the adjustment assembly 20 is driven to rotate about the second rotation axis 23 by the drive motor 41. Therefore, after the vehicle is powered off, the downward movement of the lower end of the pedal assembly 30 can meet the avoidance requirements, avoid the pedal assembly 30 from occupying a large space, facilitate the driver's entry and exit of the vehicle or perform other operations, and help ensure the intelligence of the brake pedal assembly 100.

[0070] According to some embodiments of the present invention, Figure 5-Figure 7 As shown, before the control and adjustment component 20 rotates around the second rotation axis 23, it also includes:

[0071] Determining whether the pedal assembly 30 is under pressure, for example, by detecting whether pressure is applied via a pressure sensor on the pedal pad 302;

[0072] If yes, a message is issued to remind the user not to step on the pedal assembly 30 until the pressure of the pedal assembly 30 disappears;

[0073] If not, the adjustment component 20 is controlled to rotate around the second rotation shaft 23 , for example, the adjustment component 20 is driven to rotate around the second rotation shaft 23 by the driving motor 41 to achieve the adjustment requirement of the pedal component 30 .

[0074] Therefore, before the pedal assembly 30 is adjusted, the driver is reminded not to step on the pedal assembly 30 to avoid the driver's feet being squeezed during the adjustment process of the pedal assembly 30, thereby avoiding safety hazards and helping to improve the safety level of the brake pedal assembly 100.

[0075] In some embodiments in which the drive motor 41 drives the adjustment assembly 20 to rotate around the second rotating shaft 23, when the pressure sensor on the pedal pad 302 detects pressure, the pressure sensor sends a signal to the control system of the vehicle, and the drive motor 41 can receive the control signal of the control system, so that the drive motor 41 is actuated to realize the control requirements of the drive motor 41.

[0076] In some embodiments of the present invention, the target angle parameter acquisition includes self-adjustment, which can determine a comfortable angle for the pedal assembly 30 based on the driver's actual pedaling habits to meet desired driving requirements. Alternatively, the target angle parameter acquisition includes direct input, where the target angle parameter is set during vehicle production for easy driver selection. This allows for flexible and personalized adjustment of the pedal assembly 30, allowing the control of the brake pedal assembly 100 to better meet the driver's needs.

[0077] According to some embodiments of the present invention, Figure 8 As shown, when the acquisition of the target angle parameter includes self-adjustment, the control method includes:

[0078] Determining whether the pedal assembly 30 is under pressure, for example, by detecting whether pressure is applied via a pressure sensor on the pedal pad 302;

[0079] If so, the adjusting assembly 20 is controlled to rotate about the second rotating shaft 23 to move the lower end of the pedal assembly 30 downward, for example, by driving the adjusting assembly 20 to rotate about the second rotating shaft 23 by the driving motor 41 until the pedal assembly 30 reaches the lower limit position, that is, the driver's foot continues to lightly step on the pedal assembly 30, so that the pedal assembly 30 reaches the lower limit position, and the target angle parameter is stored; or, after the pressure on the pedal assembly 30 disappears, that is, when the driver's foot reaches a comfortable human-machine posture and does not step on the pedal assembly 30, the adjusting assembly 20 is controlled to rotate about the second rotating shaft 23 to move the lower end of the pedal assembly 30 upward until the pedal assembly 30 is again under pressure, that is, the position where the driver's foot steps on the pedal assembly 30, and the target angle parameter is stored;

[0080] If not, the control adjustment assembly 20 is rotated about the second rotating shaft 23 to move the lower end of the pedal assembly 30 upward until the pedal assembly 30 reaches the upper limit position, that is, the driver's foot does not step on the pedal assembly 30, so that the pedal assembly 30 reaches the upper limit position, and the target angle parameter is stored; or, the pedal assembly 30 is in a position where pressure is applied, that is, the driver's foot is in a comfortable human-machine posture, and the pedal assembly 30 is adjusted to contact the driver's foot, and the target angle parameter is stored.

[0081] Therefore, by the above-mentioned method of obtaining the target angle parameters, the target angle parameters for the driver to be in a comfortable human-machine posture can be accurately obtained, which facilitates the adjustment of the pedal assembly 30 to a comfortable angle, and is conducive to improving driving comfort and convenience.

[0082] The vehicle according to the embodiment of the present invention includes a brake pedal assembly 100 according to the embodiment of the present invention. Because the brake pedal assembly 100 according to the embodiment of the present invention has the aforementioned beneficial technical effects, the vehicle according to the embodiment of the present invention is connected to the adjustment body 21 via the first rotating shaft 22 and the second rotating shaft 23. The second rotating shaft 23 is located below the first rotating shaft 22 and is rotationally connected to the pedal bracket 10. The upper end of the pedal assembly 30 is rotationally connected to the first rotating shaft 22. This allows the pedal assembly 30 to be adjusted via the adjustment body 21 to accommodate different drivers' pedaling habits and legroom requirements, ensuring the comfort of the pedal assembly 30. Furthermore, the problem of uneven transition between the accelerator pedal and the pedal assembly 30 after adjustment, which may be caused by the coaxiality of the first rotating shaft 22 and the second rotating shaft 23, is avoided. This satisfies the adjustment of the pedal assembly 30 with a constant lever ratio, while simultaneously occupying a small volume, reducing layout space, and facilitating platformization.

[0083] In some embodiments, the vehicle includes a dash panel, and the pedal bracket 10 is fixed to the dash panel, ensuring that the pedal bracket 10 is securely fixed on the vehicle, facilitating assembly, and ensuring a compact structure.
