The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] like Figures 1 to 15As shown, this embodiment provides a braking system and a vehicle. The vehicle includes a braking system comprising a brake caliper 1, a force detection element 2, a power unit 3, and an electrical connector 4. The brake caliper 1 provides braking force to the wheel end. The brake caliper 1 includes a caliper body 11. The force detection element 2 is mounted on the caliper body 11 and can detect the force value of the braking force provided by the brake caliper 1. The power unit 3 includes a power housing 31 and a circuit board 32 disposed on the power housing 31. The power housing 31 is connected to one side of the caliper body 11 along a first direction and has a limiting structure. One end of the electrical connector 4 is electrically connected to one side of the circuit board 32 along the first direction, and the other end of the electrical connector 4 is electrically connected to one side of the force detection element 2 along a second direction. The two ends of the electrical connector 4 along the first direction respectively abut against the circuit board 32 and the caliper body 11. The limiting structure can prevent the electrical connector 4 from moving along the second direction. The second direction is perpendicular to the first direction.

[0050] The braking system of this embodiment clamps the electrical connector 4 with the circuit board 32 and the clamp 11 to limit the position of the electrical connector 4 in the first direction, and prevents the electrical connector 4 from moving in the second direction by the limiting structure, thereby limiting the position of the electrical connector 4 in the second direction. This avoids relative displacement between the electrical connector 4 and the force detection element 2, and between the electrical connector 4 and the circuit board 32, thereby improving the connection stability between the electrical connector 4 and the force detection element 2, and between the electrical connector 4 and the circuit board 32.

[0051] Optionally, the clamp body 11 is provided with a first limiting part, and the electrical connector 4 abuts against one side of the first limiting part along the third direction; the first direction and the second direction are perpendicular to each other with the third direction, so that the position of the electrical connector 4 in the third direction can be limited by the first limiting part to prevent the electrical connector 4 from moving along the third direction, thereby further improving the installation stability of the electrical connector 4.

[0052] Optionally, such as Figures 2 to 5 As shown, the clamp body 11 has a mounting groove 111 on the side facing the power housing 31. The end of the electrical connector 4 connected to the force detection element 2 is inserted into the mounting groove 111, which allows the electrical connector 4 to be installed more stably on the clamp body 11, which is beneficial to further improve the installation stability of the electrical connector 4.

[0053] Furthermore, the mounting groove 111 includes a first groove sidewall 1111, which is located on one side of the mounting groove 111 along a third direction. The electrical connector 4 abuts against the first groove sidewall 1111, thereby preventing the electrical connector 4 from moving along a third direction. In other words, by using the first groove sidewall 1111 as the first limiting part, it is possible not only to provide a stable blocking effect on the electrical connector 4 through the first limiting part, but also to facilitate processing and assembly.

[0054] Specifically, there are two first groove sidewalls 1111, and the two first groove sidewalls 1111 respectively abut against the electrical connector 4 on both sides along the third direction.

[0055] Furthermore, the mounting groove 111 includes a second groove sidewall 1112, which is located on one side of the mounting groove 111 along the second direction; a gap is provided between the electrical connector 4 and the second groove sidewall 1112, that is, the electrical connector 4 can move within the mounting groove 111 along the second direction, thereby improving the assembly convenience of the electrical connector 4.

[0056] It should be noted that in this embodiment, the electrical connector 4 is installed in the mounting groove 111 and clamped by the two first groove sidewalls 1111. After the power housing 31 and the clamp body 11 are assembled, the electrical connector 4 is clamped and fixed by the power housing 31 and the clamp body 11. During the operation of the braking system, the electrical connector 4 will not move relative to the clamp body 11.

[0057] Optionally, such as Figure 3 and Figure 6 As shown, the limiting structure includes a mounting hole 311. One end of the electrical connector 4 connected to the circuit board 32 is inserted into the mounting hole 311 with an interference fit. In other words, the inner wall of the mounting hole 311 can hold the end of the electrical connector 4 connected to the circuit board 32 tightly, thereby blocking the electrical connector 4 through the inner wall of the mounting hole 311 to prevent the electrical connector 4 from moving. This not only improves the positioning effect of the electrical connector 4, but also has a simple structure that is easy to process and assemble.

[0058] Optionally, such as Figure 3 and Figure 7 As shown, the outer periphery of the end of the electrical connector 4 that is connected to the circuit board 32 is provided with a boss 41, which is inserted into the mounting hole 311 with an interference fit.

[0059] Optionally, the force detection element 2 is provided with a first connecting structure, and the clamp body 11 is provided with a second connecting structure. The first connecting structure can be inserted into the second connecting structure along a first direction, thereby preventing the force detection element 2 from shifting relative to the clamp body 11, improving the installation stability of the force detection element 2, and thus improving the detection accuracy and reliability of the force detection element 2. Furthermore, the interference fit between the first connecting structure and the second connecting structure can further improve the positioning stability of the force detection element 2.

[0060] Specifically, such as Figures 8 to 12 As shown, the first connecting structure includes at least one pin 21, and the second connecting structure includes at least one socket 112, with the pins 21 inserted into the sockets 112 in a corresponding manner. Furthermore, the pins 21 and the sockets 112 are interference-fitted.

[0061] For example, there are three pins 21 and three sockets 112. Of course, there can also be two, four, five, or even more pins 21 and sockets 112, which is not limited here. It should be noted that there can also be one pin 21 and one socket 112, and the cross-section of the pin 21 is non-circular, and the cross-section of the socket 112 is the same as the cross-section of the pin 21, so that the pin 21 can be inserted into the socket 112 to prevent the force detection element 2 from translating and rotating relative to the clamp body 11. Specifically, the cross-section of the pin 21 is perpendicular to the axial direction of the pin 21; the cross-section of the socket 112 is perpendicular to the axial direction of the socket 112; and the axial direction of the pin 21 is parallel to the axial direction of the socket 112.

[0062] In this embodiment, the pin 21 is fixed inside the socket 112, for example, as shown in the example. Figure 8 and Figure 10 As shown, the pin 21 is fixed in the socket 112 by riveting method such as hot riveting, which can prevent the force detection component 2 from moving relative to the clamp body 11 and prevent the force detection component 2 from detaching from the clamp body 11, thereby further improving the installation stability of the force detection component 2.

[0063] In other embodiments, the first connecting structure is provided with a snap-fit ​​part, and the second connecting structure is provided with a snap-fit ​​mating part. When the first connecting structure and the second connecting structure are inserted along the first direction, the snap-fit ​​part and the snap-fit ​​mating part snap together, thereby preventing the force detection element 2 from moving relative to the clamp body 11 and preventing the force detection element 2 from disengaging from the clamp body 11, further improving the installation stability of the force detection element 2.

[0064] For example, such as Figure 8 and Figure 11 As shown, the latching part is a latching protrusion 221 provided on the pin 21, and the latching mating part is a latching groove provided on the inner wall of the insertion hole 112. When the pin 21 is inserted into the insertion hole 112, the latching protrusion 221 is engaged in the latching groove. Of course, the latching part can also be a latching groove provided on the pin 21, and the latching mating part can be a latching protrusion 221 provided on the inner wall of the insertion hole 112.

[0065] Furthermore, the pin 21 includes a main body 211 and two separate parts 212. Along the axial direction of the pin 21, one end of the main body 211 is connected to the force detection element 2, and the other end is connected to the two separate parts 212. The two separate parts 212 are arranged radially apart along the pin 21. Each of the two separate parts 212 is provided with a locking protrusion 221. Both locking protrusions 221 can be engaged in the locking groove. When the locking protrusions 221 are engaged with the locking groove, the two separate parts 212 can undergo elastic deformation, thereby improving the convenience and stability of assembling the force detection element 2 and the clamp body 11.

[0066] Of course, such as Figure 8 and Figure 12As shown, the snap-fit ​​part can also be a limiting groove 222 provided in the pin 21, and the snap-fit ​​mating part can be a snap ring provided in the insertion hole 112. When the pin 21 is inserted into the insertion hole 112, the snap ring is snapped into the limiting groove 222. Alternatively, the snap-fit ​​part can be a snap ring, and the snap-fit ​​mating part can be a limiting groove 222 provided in the inner wall of the insertion hole 112.

[0067] Optionally, the circuit board 32 is adjustablely positioned on the power housing 31 along the first direction. By adjusting the position of the circuit board 32 along the first direction, the clamping force between the electrical connector 4 and the circuit board 32 can be adjusted, thereby ensuring the reliability of the connection between the electrical connector 4 and the circuit board 32.

[0068] For example, the power housing 31 includes a mounting part, which is provided with a plurality of slots spaced apart along a first direction. By snapping the circuit board 32 into different slots, the position of the circuit board 32 along the first direction can be adjusted.

[0069] In this embodiment, the electrical connector 4 includes a first connecting portion 4a and a second connecting portion 4b. One end of the first connecting portion 4a is electrically connected to the circuit board 32; one end of the second connecting portion 4b is electrically connected to the force detection element 2, and the other end of the second connecting portion 4b is connected to the other end of the first connecting portion 4a and forms an L-shaped structure. This reduces the pressure at the connection between the first connecting portion 4a and the circuit board 32, and at the connection between the second connecting portion 4b and the force detection element 2, thereby improving the connection reliability between the electrical connector 4 and the circuit board 32, and between the electrical connector 4 and the force detection element 2.

[0070] Optionally, such as Figure 7 , Figures 13 to 15 As shown, the electrical connector 4 includes a first terminal 4a1 that is electrically connected to the circuit board 32. That is, the first terminal 4a1 is located at the end of the first connecting portion 4a opposite to the second connecting portion 4b. Further, the first terminal 4a1 is a pogo pin (e.g.,...). Figure 13 (as shown) or spring pin (such as) Figure 14 As shown), this improves the ease of connection between the electrical connector 4 and the circuit board 32. Alternatively, the first terminal 4a1 can also be a solder pin (such as...). Figure 15 (As shown).

[0071] Specifically, the circuit board 32 has three first interfaces, namely power supply, signal, and ground. Further, there are three first terminals 4a1, each connected to one of the three first interfaces to achieve signal transmission. For example, the first interface is a PIN contact plane, which abuts against the first terminal 4a1 to achieve signal transmission.

[0072] Furthermore, the three first interfaces are positioned directly opposite the mounting holes 311, so that when the end of the electrical connector 4 connected to the circuit board 32 is inserted into the mounting hole 311, the three first terminals 4a1 can be connected to the three first interfaces respectively. For example, the circuit board 32 is a PCB (printed circuit board), which offers a high level of automation, high reliability, and a longer service life.

[0073] Optionally, the electrical connector 4 includes a second terminal 4b1 electrically connected to the force sensing element 2; that is, the second terminal 4b1 is located at the end of the second connecting portion 4b opposite to the first connecting portion 4a. Further, the second terminal 4b1 is a pogo pin (e.g.,...). Figure 13 (as shown) or spring pin (such as) Figure 14 As shown, this improves the ease of connection between the electrical connector 4 and the circuit board 32. Alternatively, the second terminal 4b1 can also be a solder pin. Specifically, the force detection element 2 is a force sensor. The force sensor has three second interfaces 23 on its side, designated for power supply, signal, and grounding, respectively. Furthermore, there are three second terminals 4b1, each connected to one of the three second interfaces 23 to transmit signals. For example, the second interface 23 is a PIN contact plane, which abuts against the second terminal 4b1 to achieve signal transmission.

[0074] For example, the assembly process of the braking system in this embodiment is as follows:

[0075] The second connecting part 4b of the electrical connector 4 is installed into the mounting groove 111, and the two first groove sidewalls 1111 respectively abut against the second connecting part 4b on both sides along the third direction to clamp the second connecting part 4b.

[0076] Insert the first connecting part 4a of the electrical connector 4 into the mounting hole 311 and make the first terminal 4a1 abut against the first interface. Then, push the electrical connector 4, thereby causing the second connecting part 4b to move in the mounting groove 111 along the second direction, so that the second terminal 4b1 abuts against the second interface 23. That is, there is a certain preload between the second terminal 4b1 and the second interface 23, which can prevent the second terminal 4b1 from disengaging from the second interface 23 when the braking system is subjected to vibration.

[0077] Then, the power housing 31 and the clamp body 11 are fixedly connected by bolts or other fasteners. The power housing 31 and the clamp body 11 can clamp the electrical connector 4 to ensure that the first terminal 4a1 is pressed against the first interface, thus preventing the first terminal 4a1 from disengaging from the first interface when the braking system is subjected to vibration.

[0078] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
