Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The following is for reference. Figures 1-5 The displacement sensing mechanism 100 of the brake pedal according to a first aspect embodiment of the present invention is described.

[0036] like Figure 1 and Figure 2 As shown, the displacement sensing mechanism 100 according to an embodiment of the present invention includes: a valve block 10, a piston 22, a push rod 23, a magnetic component 24, an elastic component 25, and a displacement sensor 30.

[0037] Here, the displacement sensor 30 detects the displacement of the magnetic component 24 and converts it into an electrical signal output. This electrical signal can represent the depth of the brake pedal, thus providing information for the vehicle's braking control.

[0038] The push rod 23 is connected to the brake pedal. When the user presses the brake pedal, the push rod 23 moves accordingly, thereby moving the magnetic component 24.

[0039] Combination Figure 1 and Figure 2 A piston 22 is movably mounted on the valve block 10 along a first direction. The piston 22 has a first end 221 and a second end 222 at its two ends along the first direction. A first inner hole 2210 is provided at the first end 221 of the piston 22. A push rod 23 is connected to the second end 222 of the piston 22, so that when the brake pedal is depressed, the push rod 23 moves towards the first end 221. A magnetic element 24 is located within the first inner hole 2210.

[0040] The shape of the first inner hole 2210 is adapted to the shape of the cross-section of the magnetic component 24 so that the magnetic component 24 can be installed into the first inner hole 2210.

[0041] The cross-sectional shape of the magnetic component 24 is not limited. For example, the cross-sectional shape of the magnetic component 24 can be circular, triangular, or rectangular. It can also be designed as a semi-circular polygon or other irregular shape. By having the magnetic component 24 in the above cross-sectional shape contact the first inner hole 2210, the matching shapes of the two can be fully utilized to ensure that the magnetic component 24 can maintain a stable attitude and position during movement, which helps to improve the sensing accuracy of the displacement sensor 30.

[0042] For example, when the driver depresses the brake pedal, the force generated by the brake pedal is directly transmitted to the second end 222 of the piston 22 via the push rod 23, pushing the piston 22 to move along a first direction, so that the magnetic element 24 in the first end 221 of the piston moves accordingly along the first direction. Figure 2 The displacement sensor 30 is mounted on the valve block 10 and is used to sense the displacement of the magnetic component 24.

[0043] To achieve the reset function, the displacement sensing mechanism 100 of this embodiment further includes an elastic element 25. The elastic element 25 is connected to at least one of the piston element 22, the push rod 23, and the magnetic element 24 to drive the push rod 23 to reset.

[0044] In some specific embodiments, one end of the elastic element 25 is fixed to the valve block 10. This forms a stable support point, which the elastic element 25 can use to effectively push the connected components to reset when the brake pedal is released, so that the push rod 23 can be stably reset.

[0045] In some alternative embodiments, the other end of the elastic element 25 is connected to the piston element 22. When the brake pedal is released, the elastic element 25 uses its restoring force to push the piston element 22 back to its initial position, ensuring that the braking system is ready for the next operation.

[0046] Alternatively, the other end of the elastic element 25 is connected to the push rod 23. When the brake pedal is released, the elastic element 25 uses its elastic potential energy to push the push rod 23 to move in the opposite direction, thereby driving the piston element 22 to reset, preparing for the next braking operation.

[0047] Alternatively, the other end of the elastic element 25 is connected to the magnetic element 24. In this way, when the brake pedal is released, the elastic element 25 can directly act on the magnetic element 24, pushing it back to its initial position, ensuring that the displacement sensor 30 can accurately sense and report the reset state of the brake pedal. Simultaneously, the piston and push rod 23 reset accordingly.

[0048] According to some optional embodiments, such as Figure 3 As shown, a protrusion 241 is provided on the outer peripheral surface of the magnetic component 24, and the protrusion 241 abuts against the inner sidewall of the first inner hole 2210.

[0049] In the above technical solution, the contact between the protrusion 241 and the inner sidewall provides a stable positioning for the magnetic component 24, preventing it from shaking or shifting during operation. At the same time, the protrusion 241 can reduce the frictional resistance between the magnetic component 24 and the inner sidewall during installation, making assembly easier.

[0050] In some optional embodiments, the protrusion 241 and the magnetic component 24 can be formed in one step. Of course, this invention is not limited to this; the protrusion 241 can also be formed after the magnetic component 24 has been formed, in which case the protrusion 241 and the magnetic component 24 can be formed after two processing steps. It is understood that regardless of the specific processing order of the protrusion 241 and the magnetic component 24, as long as the protrusion 241 and the magnetic component 24 form an integrated structure after the overall processing is completed, it is acceptable.

[0051] In some optional embodiments, the protrusion 241 is provided around the outer periphery of the magnetic member 24 at least once, thereby enhancing the tightness of the fit between the magnetic member 24 and the first inner hole 2210. At the same time, it makes the force on the magnetic member 24 more evenly distributed, improving the overall stability and durability.

[0052] In some alternative embodiments, combined with Figure 3 The outer peripheral surface of the magnetic component 24 is clearance-fitted with the inner wall of the first inner hole 2210.

[0053] Clearance fit can reduce frictional resistance during assembly, making assembly easier.

[0054] According to some optional embodiments of the present invention, such as Figure 4 As shown, there are multiple protrusions 241, which are spaced apart along the outer peripheral surface of the magnetic component 24. This design helps guide the outer peripheral surface of the magnetic component 24 to form a clearance fit with the inner wall of the first inner hole 2210. This spaced arrangement ensures sufficient contact between the protrusions 241 and the inner wall, while avoiding installation difficulties or stress concentration problems caused by excessively dense protrusions 241.

[0055] In some specific embodiments, the protrusion 241 is elongated and extends along a first direction. This facilitates the guidance of the installation of the magnetic component 24.

[0056] According to some optional embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the elastic element 25 includes a first spring 251. The displacement sensing mechanism 100 also includes a spring seat 50, which is located on the side of the magnetic element 24 away from the push rod 23. The first spring 251 abuts against the spring seat 50 and is located on the side of the magnetic element 24 away from the push rod 23.

[0057] First, the spring seat 50 acts as a bridge between the magnetic component 24 and the first spring 251, improving the efficiency of displacement transmission. When the magnetic component 24 is displaced due to external factors (such as changes in the magnetic field, mechanical force, etc.), this displacement can be quickly and effectively transmitted to the first spring 251 through the spring seat 50. This not only ensures the accuracy of displacement measurement but also improves the response speed of the entire displacement sensing mechanism 100.

[0058] Secondly, the spring seat 50 serves as a buffer layer between the magnetic component 24 and the first spring 251, reducing direct friction and wear between the two, thereby extending the service life of the entire mechanism.

[0059] Furthermore, the spring seat 50 also serves to uniformly transmit external forces. During displacement, the external force on the magnetic component 24 can be uniformly transmitted to the first spring 251 through the spring seat 50, avoiding excessive pressure on the spring in local areas, thereby preventing uneven deformation or premature failure. Similarly, when the first spring 251 generates elastic force due to deformation, the spring seat 50 can also ensure that this elastic force is uniformly applied to the magnetic component 24, preventing the magnetic component 24 from tilting, twisting, or being damaged due to uneven force.

[0060] In summary, by setting the spring seat 50, the overall structure of the displacement sensing mechanism 100 becomes more stable, and its displacement transmission efficiency, service life, and wear resistance are all improved to a certain extent.

[0061] According to some optional embodiments, in combination Figure 2 The spring seat 50 includes a guide post 51 and a base 52, with the base 52 connected to the outer peripheral surface of the guide post 51 and disposed near the magnetic element 24.

[0062] Here, the base 52 serves to support and transmit forces.

[0063] Alternatively, the base 52 may be annular or disc-shaped. The size and shape of the base 52 are adapted to the dimensions of the magnetic element 24 and the first spring 251.

[0064] One side of the base 52 is connected to the guide post 51, and the other side is adjacent to the magnetic component 24 to ensure that the displacement of the magnetic component 24 can be smoothly transmitted to the first spring 251.

[0065] The base 52 has a contact surface that matches the first spring 251. Optionally, the contact surface can be a plane, a slope, or other shape to ensure that the first spring 251 can stably abut against the base 52 and generate a uniform elastic force to optimize the efficiency and stability of displacement transmission.

[0066] The first spring 251 is sleeved on the guide post 51 and abuts against the base 52. When the magnetic component 24 is displaced due to external factors, it will push the base 52 and the guide post 51 to move together, thereby compressing or stretching the first spring 251. Due to the presence of the guide post 51, the first spring 251 can maintain stable contact with the magnetic component 24 during deformation, avoiding the first spring 251 from detaching due to tilting, torsion, etc.

[0067] See Figure 2 and Figure 5As shown, some optional displacement sensing mechanisms 100 according to this utility model also include a baffle 40, which is interference-fitted in the first inner hole 2210 and located on the side of the magnetic member 24 away from the push rod 23.

[0068] Thus, the baffle 40 is positioned between the magnetic component 24 and the first spring 251. Since the baffle 40 is installed within the first inner hole 2210 via an interference fit, this means the outer diameter of the baffle 40 is slightly larger than the inner diameter of the first inner hole 2210. Therefore, the baffle 40 is subjected to a certain amount of compression during installation, thus tightly fitting against the inner wall of the first inner hole 2210. This installation method ensures the stability and reliability of the baffle 40, preventing it from loosening or falling off during displacement.

[0069] In some alternative embodiments, the baffle 40 is an open annular shape. The open annular shape allows the baffle 40 to be easily expanded or compressed before installation to accommodate the dimensions of the first inner bore 2210, thereby simplifying the installation process.

[0070] Specifically, during installation, simply expand or compress the open annular baffle 40 slightly and then slide it into the first inner hole 2210. Once it reaches the predetermined position, due to the elastic restoring force of the material, the baffle 40 will automatically return to its original size, forming a tight interference fit.

[0071] It should be noted that the "open ring" mentioned in this article refers to a ring with an opening (i.e., a non-closed ring). Here, "ring" is interpreted in a broad sense, that is, it is not limited to "circular ring", but can also be "polygonal ring", etc.

[0072] According to some such Figure 1 In the embodiment shown, a main cylinder bore 101 is formed in the valve block 10, and the main cylinder bore 101 extends along a first direction. One end of the main cylinder bore 101 is a mating end 101a. The piston member 22 is located in the main cylinder bore 101, and the push rod 23 is connected to the piston member 22 via the mating end 101a.

[0073] In the above technical solution, the shape and size of the main cylinder bore 101 are adapted to the piston component 22 to ensure a good fit between the two.

[0074] This also confines the piston 22 within the valve block 10, limiting its range of movement in the first direction. When the push rod 23 moves the piston 22, it can only move within a predetermined stroke within the master cylinder bore 101, thus avoiding the risk of excessive movement or disengagement from the master cylinder bore 101. Simultaneously, this limitation ensures that the piston 22 will not tilt or deflect due to lateral forces during movement.

[0075] One end of the main cylinder bore 101 is configured as a mating end 101a. Optionally, the mating end 101a includes a flange or other connection structure to confine the piston member 22 within the main cylinder bore 101.

[0076] In some alternative embodiments, combined with Figure 2 The valve block 10 is provided with a mounting groove 102, which is located near or connected to the main cylinder bore 101, and is parallel to the main cylinder bore 101. The displacement sensor 30 is installed in the mounting groove 102.

[0077] The mounting slot 102 is positioned near or connected to the main cylinder bore 101. This arrangement allows the displacement sensor 30 to monitor the movement of the magnetic component 24 inside the piston component 22 more directly and accurately.

[0078] The mounting slot 102 is set parallel to the main cylinder bore 101, ensuring the stability and accuracy of the displacement sensor 30 during the measurement process.

[0079] This configuration allows the displacement sensor 30 to monitor the movement of the magnetic component 24 within the main cylinder bore 101 in real time and convert the displacement data into electrical signals, which are then output to the control system. By analyzing this displacement data, the control system can precisely control parameters such as the moving speed and position of the piston component 22, thereby meeting the needs of various application scenarios.

[0080] In some alternative embodiments, such as Figure 1 As shown, the elastic element 25 includes a second spring 252. The displacement sensing mechanism 100 also includes a valve seat 60 fixed to one end of the valve block 10, with a connecting hole 61 formed on the valve seat 60. The connecting hole 61 is directly opposite to the main cylinder bore 101, and the piston element 22 is located in the connecting hole 61 and the main cylinder bore 101.

[0081] The second spring 252 is used to provide a restoring force to ensure that the push rod 23 can quickly and accurately return to its initial position after the external force disappears.

[0082] The valve seat 60 is securely fixed to one end of the valve block 10, maintaining a certain axial distance from the main cylinder bore 101 to ensure that the piston 22 can move freely within the main cylinder bore 101.

[0083] A connecting hole 61 is formed on the valve seat 60, which is directly opposite to the main cylinder bore 101, so that the piston 22 can pass smoothly through the valve seat 60 and move within the main cylinder bore 101.

[0084] Optionally, the shape and size of the connecting hole 61 should match the main cylinder bore 101 to ensure the smoothness and stability of the piston component 22 during movement.

[0085] One end of the second spring 252 abuts against the valve seat 60, while the other end is indirectly connected to the push rod 23. This ensures that the spring's restoring force can be stably transmitted to the push rod 23.

[0086] Optionally, the indirect connection between the second spring 252 and the valve seat 60 can be achieved through an intermediate connector.

[0087] Combination Figure 1 In some optional embodiments, the elastic element 25 further includes a third spring 253. One end of the third spring 253 abuts against the bottom wall of the main cylinder bore 101, and the other end of the third spring 253 is connected to the first spring 251 via a linkage piston.

[0088] A vehicle according to a second aspect of the present invention includes a displacement sensing mechanism 100 for a brake pedal according to a first aspect of the present invention.

[0089] It is worth noting that the specific type of vehicle referred to in this application is not limited. For example, the vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, range-extended electric vehicles, solar-powered electric vehicles, gas fuel vehicles (such as hydrogen engine vehicles), or biofuel vehicles (such as vehicles powered by ethanol, biodiesel, etc.). The vehicle using this embodiment of the invention, with its improved brake pedal displacement sensing mechanism 100, facilitates more precise braking control, improving driving safety and stability. In emergency braking situations, it can respond quickly to shorten the braking distance, thereby ensuring passenger safety.
