For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] Reference will be made below to Figure 1 - Figure 6 describe a brake pedal structure 100 according to an embodiment of the present utility model.

[0032] As Figure 1 shown, a brake pedal structure 100 according to an embodiment of the present utility model.

[0033] The above-mentioned brake pedal structure 100 includes: a bracket 10, an operating member 20, and a force transmission motor 30. The operating member 20 includes a rotating portion 21 and a force applying portion 22, and the rotating portion 21 is rotatably connected to the bracket 10.

[0034] Among them, the bracket 10 is the basis for installing the brake pedal, providing a stable support platform for the brake pedal and its related components. It is used to ensure that the brake pedal can maintain a stable posture during vehicle driving and will not be displaced or deformed due to vehicle vibration or external force.

[0035] Optionally, the bracket 10 fixes the brake pedal and its connecting components to the vehicle through fasteners such as bolts and nuts, preventing loosening or falling off during emergency braking or high-speed driving, and ensuring the safety and reliability of the braking system.

[0036] When the driver steps on the brake pedal, the generated braking force needs to be transmitted to other components of the brake pedal system through the bracket 10. As a bridge for force conduction, the structure of the bracket 10 has a certain stability to ensure the force transmission efficiency.

[0037] As Figure 2 shown, the operating member 20 includes a rotating portion 21 and a force applying portion 22, and the rotating portion 21 is rotatably connected to the bracket 10.

[0038] The rotating portion 21 is the core part of the operating member 20, and it can be rotatably connected to the bracket 10 through bearings, bushings or other rotating connection structures. This rotating connection method allows the rotating portion 21 to perform a smooth and stable rotational movement around a fixed axis when the driver steps on the force applying portion 22.

[0039] As Figure 1 - Figure 4As shown in the figure, the power transmission motor 30 is installed on the bracket 10. The motor shaft 31 of the power transmission motor 30 is connected to the operating member 20 to output torque as the feedback force. The power transmission motor 30 includes a detection member 32, and the detection member 32 is used to detect the rotation amplitude of the operating member 20.

[0040] For the detection member 32, when the driver steps on the force application portion 22, the force application portion 22 transmits the force to the rotation portion 21. The rotation portion 21 then begins to rotate around the axis on the bracket 10. During this process, the detection member 32 will monitor the information of the rotation portion 21 in real time. This information can be the rotation amplitude and / or the displacement of the force application portion 22 (i.e., the force and depth of the driver stepping on the pedal).

[0041] Since the power transmission motor 30 and the detection member 32 are electrically connected, the power transmission motor 30 can adjust the torque according to the rotation amplitude detected by the detection member 32.

[0042] After the detection member 32 performs the detection, the monitored information of the rotation portion 21, such as the rotation amplitude or the displacement of the force application portion 22, is fed back to the control system. The control system then adjusts the torque output by the power transmission motor 30 according to the detected information to achieve precise control of the braking force.

[0043] It should be noted that the torque output by the power transmission motor 30 is the pedal force. In the automotive braking system, the pedal force refers to the feedback force from the pedal that the driver feels during the process of stepping on the brake pedal. The magnitude and characteristics of the pedal force will directly affect the driver's braking experience and braking effect. An appropriate pedal force can enhance the driver's sense of control over the vehicle, improving the immersion and safety of driving. If the pedal force is too large, it may cause the driver to lack confidence in braking and affect driving safety. On the contrary, if the pedal force is too small, it may lead to insufficiently sensitive braking response, which will also affect the safety and stability of driving.

[0044] Therefore, by outputting a feedback force corresponding to the driver's stepping force, the power transmission motor 30 can simulate the real road feeling during braking under different road conditions. This feedback force allows the driver to more intuitively feel the response of the braking system and the braking state of the vehicle, thereby enhancing the immersion and safety of driving.

[0045] In addition, because the servo force of the power transmission motor 30 can achieve five-level adjustment of the feedback force within a preset range according to the magnitude of the current input, the power transmission motor 30 can finely adjust the force it outputs, enhancing the precision and controllability of driving. The driver can more clearly perceive and control the braking process, reducing misoperations or discomfort caused by excessive or insufficient feedback force.

[0046] According to the brake pedal structure 100 of some embodiments of the present utility model, the force transmission motor 30 further includes: a speed reducer 33, and the output end of the speed reducer 33 is connected to the operating member 20 to achieve speed reduction and torque increase.

[0047] Optionally, the interior of the speed reducer 33 includes: transmission mechanisms such as gears and worm gears. The speed reducer 33 can convert the torque output of the force transmission motor 30 into a low-speed and high-torque output through these transmission mechanisms. Therefore, the speed reducer 33 can reduce energy loss during the transmission process and improve the transmission efficiency. This means that at the same motor output power, the speed reducer 33 can transmit more torque to the braking system, thereby enhancing the braking effect.

[0048] Specifically, when the driver steps on the force application part 22 of the brake pedal, the displacement of the force application part 22 is measured and captured by the detection member 32. Subsequently, the displacement information is transmitted to the control system, and the control system calculates the required torque signal based on this and instructs the force transmission motor 30 to make corresponding adjustments.

[0049] After receiving the torque signal, the force transmission motor 30 adjusts its internal mechanism to generate a torque output that matches the torque signal. The speed reducer 33 converts the high-speed and low-torque output of the force transmission motor 30 into low-speed and high-torque. This process not only effectively reduces energy loss during the transmission process but also improves the transmission efficiency to a certain extent.

[0050] Finally, the torque processed by the speed reducer 33 for speed reduction and torque increase is transmitted to the operating member 20, and then acts to provide a feedback force to achieve precise control of vehicle braking. Through the speed reducer 33, not only the braking effect is enhanced, but also the driver's sense of control during braking is improved, making the braking process smoother and more reliable.

[0051] According to the brake pedal structure 100 of some embodiments of the present utility model, the detection member 32 includes at least one of a distance sensor and an angular sensor.

[0052] When the detection member 32 is an angular sensor, the angular sensor reflects the stepping force and angle of the driver on the brake pedal by measuring the angle change between the force application part 22 and a certain reference point (such as the bracket 10). Such an angular sensor generally uses principles such as the Hall effect, magnetoresistive effect, or photoelectric effect to convert the angle change into an electrical signal output. The angular sensor can accurately measure the angle change of the brake pedal and provide accurate control signals. At the same time, the angular sensor also has a relatively fast response speed, so it can track the dynamic changes of the brake pedal in real time to ensure the timely response of the braking system.

[0053] When the detection member 32 is a distance sensor, the distance sensor reflects the braking force of the driver by measuring the displacement of the force application part 22 during the stepping process (i.e., the moving distance of the force application part 22). Such a distance sensor can utilize capacitance change, resistance change, or optical principle, etc., to convert the displacement into an electrical signal for output. The distance sensor can directly measure the displacement of the force application part 22, thereby more intuitively reflecting the stepping force and braking demand of the driver.

[0054] To more accurately judge the braking intention and force of the driver, the detection member 32 includes a rotation angle sensor and a distance sensor. When the two are used in combination, multi-directional detection and control of the force application part 22 can be achieved, thereby realizing more precise control of the braking process. This helps the force transmission motor 30 output a feedback force according to accurate information.

[0055] Alternatively, the detection member 32 may further include: a force sensor, an acceleration sensor, and other devices that can be used to monitor and feedback the operating state of the brake pedal in real time.

[0056] As Figure 1 shown, the brake pedal structure 100 according to some embodiments of the present invention further includes: an installation box 11 installed on the bracket 10 and located at one end of the rotating part 21, and the detection member 32 and the force transmission motor 30 are both integrated in the installation box 11.

[0057] The layout of the installation box 11 can make full use of the space of the driver's seat, and also ensures the close cooperation and smooth operation among multiple components.

[0058] Optionally, the installation box 11 is made of a high-strength and corrosion-resistant material part. This can ensure its stability and durability during long-term use.

[0059] The detection member 32 is integrated inside the installation box 11. Key parameters such as the displacement of the brake pedal can be monitored in real time through the detection member 32.

[0060] In addition to the detection member 32, the force transmission motor 30 is also integrated in the installation box 11. After receiving the information from the detection member 32, the force transmission motor 30 can quickly respond and generate a corresponding output torque, thereby assisting or enhancing the movement of the brake pedal.

[0061] According to the brake pedal structure 100 of some embodiments of the present invention, as Figure 2 - Figure 4 shown, the operating member 20 has a use range a and / or a storage position b on the bracket 10, the storage position b deviates from the use range a, and when the operating member 20 is in the storage position b, the output torque of the force transmission motor 30 is zero.

[0062] Combined with Figure 2, the usage range a refers to the spatial area where the driver's foot applies force during normal driving to generate a braking effect on the brake pedal structure 100. In combination with Figure 3 - Figure 4 , the storage position b is a position deviated from the usage range a, which is configured to retract the brake pedal under specific working conditions to optimize the interior space layout of the vehicle.

[0063] Specifically, when the operating member 20 is in the storage position b, the output torque of the power transmission motor 30 is adjusted to zero. The operating member 20 rotates along a preset rotation axis L (usually the rotation axis L of the rotating part 21). In combination with Figure 3 - Figure 4 , this rotation includes flipping up or flipping down. Through this rotation, it is ensured that the operating member 20 of the brake pedal structure 100 does not occupy the space in the cockpit when being stored, releasing the space originally used for stepping on. This space release means that for the driver, their feet can have a larger activity space under specific working conditions (such as in the autonomous driving mode, during rest, etc.), which helps to relieve the fatigue of long - distance driving and improve the riding comfort.

[0064] From the perspective of safety, the design of the storage position b also takes into account the leg protection during a collision. When a vehicle collision occurs, the retracted brake pedal can reduce the potential harm to the driver's legs, providing additional safety protection for the driver. In addition, the automatic storage function of the brake pedal also increases the driving convenience. The driver can enjoy a larger foot space without manually adjusting the operating member 20, thereby improving the intelligent level of the vehicle.

[0065] According to the brake pedal structure 100 of some embodiments of the present utility model, as Figure 5 and Figure 6 shown, the operating member 20 has a storage position b on the bracket 10. The brake pedal structure 100 includes a positioning member 40, and the positioning member 40 is provided on the bracket 10 and is used to position the operating member 20 at the storage position b.

[0066] The function of the positioning member 40 is to provide a reliable support and locking mechanism for the operating member 20 when it is in the storage position b. This ensures that once the operating member 20 rotates and is located at the storage position b, it can be fixed there and will not be easily loosened or moved due to vibrations, bumps or other external factors during vehicle driving.

[0067] In some alternative embodiments, a magnetic material member is provided on one of the positioning member 40 and the operating member 20, and a magnetic attraction fitting member is provided on the other. A mutual attraction force can be generated between the magnetic material member and the magnetic attraction fitting member. When the operating member 20 approaches the storage position b, the attraction force between the magnetic material member and the magnetic attraction fitting member will guide the operating member 20 to automatically align and adsorb on the storage position b, achieving contactless and rapid locking. When unlocking, the driver can apply a slight force to the operating member 20 to overcome the magnetic force, causing the operating member 20 to disengage from the locked state. Alternatively, a magnetic material member is provided on the positioning member 40, and the magnetic material member provides magnetic force through an electric current. When unlocking is required, the driver can manually operate a control switch or button, and this operation will send a signal to the electromagnet to reduce the current intensity flowing through it or directly turn off the current. As the current decreases or is turned off, the magnetic force generated by the electromagnet will also weaken or disappear accordingly. At this time, the operating member 20 that was originally firmly adsorbed on the storage position b by the magnetic force will no longer be subjected to sufficient attraction force, causing the operating member 20 to disengage from the locked state and return to its operable range.

[0068] In some embodiments, the positioning member 40 is movably provided on the bracket 10. The positioning member 40 has a first position and a second position. The positioning member 40 includes a reset member for driving the positioning member 40 to move from the first position to the second position. Optionally, the reset member is a spring. In the first position, the positioning member 40 is used to stop the operating member 20 at the storage position b. This locked state ensures that the operating member 20 can be stably held at the storage position b when not in use, and will not accidentally move or become loose due to vehicle vibration or other external factors. When the positioning member 40 is in the first position, the spring is stretched and deformed, storing elastic potential energy.

[0069] When the brake pedal needs to be used, the driver can manually or electrically, pneumatically, etc., release the positioning member 40 from the first position. During this process, the spring releases elastic potential energy, the elastic member 50 retracts, and then drives the positioning member 40 to move to the second position.

[0070] In some embodiments, as Figure 5 and Figure 6 shown, the bracket 10 is provided with a mounting hole 12. The mounting hole 12 extends along the rotation axis L of the operating member 20. The positioning member 40 is movably provided in the mounting hole 12. One end of the positioning member 40 extends out of the mounting hole 12. An elastic member 50 for abutting against the positioning member 40 is provided in the mounting hole 12. When the operating member 20 is in the storage position b, the positioning member 40 abuts against the operating member 20.

[0071] The operating member 20 is provided with a groove adapted to the positioning member 40. When the operating member 20 is rotated to the storage position b, one end of the positioning member 40 will be inserted into the groove of the operating member 20. This ensures that the operating member 20 can be stably positioned when it reaches the storage position b, preventing accidental movement or rotation, thereby ensuring the overall stability and safety of the brake pedal structure 100.

[0072] At this time, the elastic member 50 is located in the mounting hole 12, applying a continuous force to the positioning member 40, so that the positioning member 40 maintains a pressing state on the operating member 20, enhancing the reliability and stability of the positioning. When it is necessary to release the positioning and rotate the operating member 20 out of the storage position b, the driver can overcome the elastic force of the elastic member 50 by means such as pressing or toggling, so that the positioning member 40 disengages from the groove, thereby allowing the operating member 20 to rotate freely.

[0073] According to the brake pedal structure 100 of some embodiments of the present invention, such as Figure 1 - Figure 4 The operating member 20 further includes: a pedal surface 23 and a pedal arm 24. The pedal surface 23 is provided on the force application portion 22, and the pedal arm 24 is connected between the rotation portion 21 and the force application portion 22.

[0074] In the above embodiment, the pedal surface 23, as the interface directly contacted by the driver, is provided above the force application portion 22. The driver controls the operating member 20 by stepping on the pedal surface 23.

[0075] In order to improve the stability of the driver during emergency braking, in some alternative embodiments, the pedal surface 23 is provided with anti-slip textures or anti-slip pads. This can prevent the driver from slipping during emergency braking. In addition, the pedal surface 23 can also be provided with reinforcing structures such as reinforcing ribs to increase its stiffness and strength.

[0076] The pedal arm 24, as a bridge connecting the rotation portion 21 and the force application portion 22, is responsible for transmitting the force applied by the driver on the pedal surface 23 to the rotation portion 21, and then triggering the action of the braking system.

[0077] Optionally, the pedal arm 24 adopts a hollow structure. The hollow structure can reduce the weight of the brake pedal structure 100, thereby meeting the lightweight requirements of the vehicle. At the same time, the pedal arm 24 is made of a material part with high strength and high stiffness. This can ensure that it has sufficient strength and stiffness.

[0078] The rotation portion 21 is the core part of the brake pedal structure 100. It receives the force from the pedal arm 24 and converts it into rotational motion, and then drives the relevant components of the braking system to work.

[0079] A vehicle according to an embodiment of the second aspect of the present invention includes the brake pedal structure 100 according to an embodiment of the first aspect of the present invention.

[0080] By setting the brake pedal structure 100, the feedback accuracy of the pedal force is enhanced, enabling the driver to experience a more delicate and accurate feedback of the pedal force when operating the brake pedal. This improvement allows the driver to more directly and clearly perceive the immediate response of the braking system and the changes in the braking state of the vehicle, thereby enhancing the handling feel and controllability during driving and ensuring more precise and safe driving behavior.

[0081] It is known that the vehicle in the present utility model can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.
