[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0036] The following is for reference. Figures 1-3 The present invention describes a vehicle cable core wire connector 100 according to an embodiment of the present invention, which is assembled in the braking system of a vehicle.

[0037] like Figures 1-3 As shown, the vehicle cable core wire connector device 100 according to an embodiment of the present invention includes: a balance block 1, the balance block 1 including a first plate 11 and a second plate 12, the first plate 11 and the second plate 12 being opposite to each other and spaced apart along a first direction, and the first plate 11 and the second plate 12 being connected; a first core wire connector 2, a stop block 3 and a fixing member 4, along a second direction, the stop block 3 and the fixing member 4 being located on one side of the balance block 1, and the stop block 3 being located between the balance block 1 and the fixing member 4, the first core wire connector 2 being located on the other side of the balance block 1. On one side, the first core wire connector 2 is connected to the fixing member 4 so that the stop block 3 is clamped between the balance block 1 and the fixing member 4, and the first direction and the second direction are perpendicular; the second core wire connector 5 extends along the first direction and passes through the first plate 11 and the second plate 12, and at least one of the stop block 3 and the second core wire connector 5 has a limiting structure 31, which is fitted with the first plate 11 and the second plate 12 to restrict the first plate 11 and the second plate 12 from moving away from each other along the first direction.

[0038] The balance block 1 can be constructed as a "U"-shaped plate structure. Along the first direction, that is, the height direction of the vehicle cable core wire connector device 100, which is... Figure 1 In the Z direction, the first plate 11 and the second plate 12 are disposed opposite to each other and spaced apart. As some embodiments of this application, the first plate 11 and the second plate 12 can be integrally formed. As some embodiments of this application, the first plate 11 and the second plate 12 can be connected by welding to reduce the risk of cracking or even breakage of the first plate 11 and the second plate 12, thereby improving the structural stability of the balance block 1.

[0039] Along the second direction, i.e. Figure 1In the X direction, the stop block 3 and the fixing member 4 are located on one side of the balance block 1, and the stop block 3 is located between the balance block 1 and the fixing member 4. That is, the balance block 1, the stop block 3, and the fixing member 4 are arranged sequentially along the second direction. The first core wire connector 2 is located on the other side of the balance block 1, that is, the first core wire connector 2 is located on the side of the balance block 1 away from the stop block 3 and the fixing member 4. As some embodiments of this application, a screw can be connected to the side of the first core wire connector 2 facing the stop block 3. The screw and the first core wire connector 2 can be integrally formed. The screw and the fixing member 4 are connected by bolts so that the stop block 3 is clamped between the balance block 1 and the fixing member 4. It should be noted that a through hole 114 can be formed at the connection between the first plate 11 and the second plate 12. The through hole 114 extends along a third direction so that the screw can pass through the through hole 114 and connect with the fixing member 4. The third direction is... Figure 1 The Y direction is perpendicular to the first, second, and third directions; that is, the X, Y, and Z directions are perpendicular to each other.

[0040] As some embodiments of this application, the first plate 11 and the second plate 12 may have a clearance notch 113 formed on the side facing the stop block 3, and the size and shape of the clearance notch 113 are adapted to the size and shape of the stop block 3. The end of the fixing member 4 facing the stop block 3 has a cylindrical notch 41, and the size and shape of the cylindrical notch 41 are adapted to the size and shape of the stop block 3. When the stop block 3 is sandwiched between the balance block 1 and the fixing member 4, part of the stop block 3 is fitted with the clearance notch 113 and part is fitted with the cylindrical notch 41, thereby reducing the risk of movement of the stop block 3 relative to the balance block 1 and the fixing member 4, and improving the relative stability of the stop block 3, the balance block 1, and the fixing member 4.

[0041] As some embodiments of this application, an auxiliary component 6 may be provided on the side of the fixing member 4 away from the stop block 3. The auxiliary component 6 may be constructed as a nut. A screw may be connected to the side of the first core wire connector 2 facing the stop block 3. The screw and the first core wire connector 2 may be integrally formed. Furthermore, the auxiliary component 6 may be threadedly connected to the screw, thereby assisting in fastening the fixing member 4 and the first core wire connector 2.

[0042] The first plate 11 may have a first through hole 111, and the second plate 12 may have a second through hole 121, with the first through hole 111 and the second through hole 121 arranged opposite to each other. There may be two first through holes 111 and two through holes 121, and there may also be two second core wire connectors 5. The two first through holes 111, the two second through holes 121, and the two second core wire connectors 5 correspond one-to-one; that is, one second core wire connector 5 corresponds to one first through hole 111 and one second through hole 121. The second core wire connector 5 extends along a first direction and passes through the first plate 11 and the second plate 12.

[0043] As some embodiments of this application, the stop block 3 has a limiting structure 31. As some embodiments of this application, the second core wire connector 5 has a limiting structure 31. As some embodiments of this application, both the stop block 3 and the second core wire connector 5 have a limiting structure 31. This application describes an example where both the stop block 3 and the second core wire connector 5 have a limiting structure 31. This arrangement helps improve the reliability of the limiting structure 31. When any one of the limiting structures 31 of the stop block 3 and the second core wire connector 5 breaks, the other limiting structures 31 can continue to perform their limiting function, thereby reducing the risk of limiting structure 31 failure.

[0044] The limiting structure 31 is assembled with both the first plate 11 and the second plate 12. When the stop block 3 and the second core wire connector 5 are assembled, the limiting structure 31 of the stop block 3 and the limiting structure 31 of the first core wire connector 2 can abut against the surfaces of the first plate 11 and the second plate 12 that are away from each other, so as to restrict the first plate 11 and the second plate 12 from moving away from each other in the first direction. This helps to reduce the risk of the core wire connector being pulled off due to the opening of the balance block 1 structure, thereby reducing the risk of braking failure of the braking system and improving the working reliability of the braking system and the safety of vehicle use.

[0045] Specifically, the vehicle's braking system also includes a front pull cable 7, a left rear pull cable 8, and a right rear pull cable 9. Each of the front pull cable 7, the left rear pull cable 8, and the right rear pull cable 9 can include a core wire 71. The core wire 71 of the front pull cable 7 can be connected to the first core wire connector 2 by means of anchoring, but is not limited to. The core wire 71 of the left rear pull cable 8 and the core wire 71 of the right rear pull cable 9 can be cast into one piece with the corresponding second core wire connector 5 by means of anchoring, but is not limited to.

[0046] When the vehicle brakes, the occupant pulls the parking brake handle, which moves the front pull cable 7. Since the core wire 71 of the front pull cable 7 is connected to the first core wire connector 2, the first core wire connector 2 is connected to the screw, and the screw is connected to the fixing member 4 so that the stop block 3 is clamped between the balance block 1 and the fixing member 4, the front pull cable 7 can pull the first core wire connector 2 to move the fixing member 4 and the stop block 3, thereby moving the balance block 1 with the front pull cable 7.

[0047] The core wire 71 of the left rear pull cable 8 and the core wire 71 of the right rear pull cable 9 are connected to the corresponding second core wire connector 5. The second core wire connector 5 passes through the first plate 11 and the second plate 12 of the balance block 1. As the balance block 1 moves with the front pull cable 7, it pulls the second core wire connector 5, thereby driving the core wire 71 of the left rear pull cable 8 and the core wire 71 of the right rear pull cable 9. The core wire 71 of the left rear pull cable 8 and the core wire 71 of the right rear pull cable 9 transmit force to the corresponding left wheel brake and right wheel brake, thereby achieving the effect of braking the vehicle.

[0048] Therefore, by having at least one of the stop block 3 and the second core wire connector 5 have a limiting structure 31, the surfaces of the first plate 11 and the second plate 12 that are away from each other can abut against the limiting structure 31, thereby restricting the first plate 11 and the second plate 12 from moving away from each other. This helps to reduce the risk of the second core wire connector 5 being pulled off due to the opening of the balance block 1 structure, thereby reducing the risk of brake failure of the braking system and improving the working reliability of the braking system and the safety of vehicle use.

[0049] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the stop block 3 has a limiting structure 31, which includes a first limiting part 311 and a second limiting part 312. The first limiting part 311 and the second limiting part 312 are arranged at intervals along a first direction. Along the first direction, the first limiting part 311 is located on the side of the first plate 11 away from the second plate 12 and is adapted to abut against the first plate 11. The second limiting part 312 is located on the side of the second plate 12 away from the first plate 11 and is adapted to abut against the second plate 12.

[0050] In some embodiments of this application, the limiting structure 31 can be integrally formed (e.g., partially upsetting) onto the stop block 3. In other embodiments, the limiting structure 31 can also be formed by machining. Along the extending direction of the stop block 3, the first limiting portion 311 and the second limiting portion 312 are respectively disposed at both ends of the stop block 3; that is, along the first direction, the first limiting portion 311 and the second limiting portion 312 are arranged at intervals. When the stop block 3 is clamped between the balance block 1 and the fixing member 4, the first limiting part 311 is located on the side of the first plate 11 away from the second plate 12, and the first limiting part 311 abuts against the surface of the first plate 11 away from the second plate 12. The second limiting part 312 is located on the side of the second plate 12 away from the first plate 11, and the second limiting part 312 abuts against the surface of the second plate 12 away from the first plate 11. This allows the first plate 11 and the second plate 12 to be clamped between the first limiting part 311 and the second limiting part 312, which helps to restrict the first plate 11 and the second plate 12 from moving away from each other, thereby reducing the risk of the second core wire connector 5 being pulled off due to the opening of the balance block 1 structure.

[0051] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the peripheral wall of the stop block 3 is formed with a first limiting part 311 and a second limiting part 312. Along the first direction, the first limiting part 311 and the second limiting part 312 are respectively adjacent to the two ends of the stop block 3. A portion of the first plate 11 and a portion of the second plate 12 are located between the first limiting part 311 and the second limiting part 312.

[0052] Along the first direction, the first limiting part 311 and the second limiting part 312 are respectively adjacent to both ends of the stop block 3. This arrangement allows for a reasonable positioning of the first limiting part 311 and the second limiting part 312, ensuring reliable clamping of the first plate 11 and the second plate 12 while minimizing the extension length of the stop block 3. This facilitates low-cost and lightweight design of the stop block 3. The first limiting part 311 and the second limiting part 312 are formed on the peripheral wall of the stop block 3. Regardless of the angle at which the stop block 3 is clamped between the fixing member 4 and the balance block 1, portions of the first plate 11 and the second plate 12 can be clamped between the first limiting part 311 and the second limiting part 312, thereby improving the limiting reliability of the first limiting part 311 and the second limiting part 312.

[0053] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, both the first limiting part 311 and the second limiting part 312 are first boss structures protruding from the stop block 3.

[0054] The first limiting part 311 and the second limiting part 312 can both be constructed as the first boss structure protruding from the stop block 3. This configuration makes the structure of the first limiting part 311 and the second limiting part 312 reasonable and helps to reduce the processing difficulty of the first limiting part 311 and the second limiting part 312. For example, the first limiting part 311 and the second limiting part 312 can be formed by local upsetting, or the first limiting part 311 and the second limiting part 312 can be formed by turning, thereby improving the production efficiency of the first limiting part 311 and the second limiting part 312.

[0055] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first boss structure is annular and is arranged around the stop block 3 along the circumference of the stop block 3.

[0056] The first boss structure can be constructed as a ring, and the first boss structure can be arranged around the stop block 3 along the circumference of the stop block 3. This arrangement can provide the first boss structure in the circumference of the stop block 3. The first boss structure and the stop block 3 are symmetrically arranged. As long as the first core wire connector 2 can be inserted through the stop block 3 and fixedly connected to the fixing member 4, regardless of whether the stop block 3 is installed upright between the fixing member 4 and the balance block 1 or installed backward between the fixing member 4 and the balance block 1, the first limiting part 311 and the second limiting part 312 can smoothly clamp the part of the first plate 11 and the part of the second plate 12, which is conducive to further improving the limiting reliability of the first limiting part 311 and the second limiting part 312.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the second core wire connector 5 has a limiting structure 31, which is formed on the peripheral wall of the second core wire connector 5. The limiting structure 31 includes a third limiting part 51 and a fourth limiting part 52 arranged at intervals along the first direction. The third limiting part 51 is located on the side of the first plate 11 away from the second plate 12 and is adapted to abut against the first plate 11. The fourth limiting part 52 is located on the side of the second plate 12 away from the first plate 11 and is adapted to abut against the second plate 12.

[0058] The limiting structure 31 of the second core wire connector 5 can be formed by, but is not limited to, casting, and is formed on the peripheral wall of the second core wire connector 5. Along the first direction, the third limiting portion 51 and the fourth limiting portion 52 are arranged at intervals. Further, along the extending direction of the second core wire connector 5, the third limiting portion 51 and the fourth limiting portion 52 are respectively formed at both ends of the second core wire connector 5. When the second core wire connector 5 is inserted into the first plate 11 and the second plate 12, the third limiting part 51 can be located on the side of the first plate 11 away from the second plate 12, and the third limiting part 51 abuts against the first plate 11. The fourth limiting part 52 is located on the side of the second plate 12 away from the first plate 11, and the fourth limiting part 52 abuts against the second plate 12. This allows the first plate 11 and the second plate 12 to be sandwiched between the third limiting part 51 and the fourth limiting part 52, which helps to further restrict the movement of the first plate 11 and the second plate 12 away from each other, thereby further reducing the risk of the second core wire connector 5 being pulled off due to the opening of the balance block 1 structure.

[0059] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the third limiting part 51 and the fourth limiting part 52 are both second boss structures that protrude from the second core wire connector 5, and the third limiting part 51 and the fourth limiting part 52 are arranged opposite to each other along the first direction.

[0060] Along the first direction, the third limiting part 51 and the fourth limiting part 52 are arranged opposite to each other so that the third limiting part 51 and the fourth limiting part 52 can reliably clamp the first plate 11 and the second plate 12. Both the third limiting part 51 and the fourth limiting part 52 can be constructed as a second boss structure protruding from the second core wire connector 5. This arrangement makes the structure of the third limiting part 51 and the fourth limiting part 52 reasonable and ensures reliable clamping.

[0061] While using the first plate 11 and the second plate 12, the extension length of the second core wire connector 5 is minimized, which is beneficial for the low-cost and lightweight design of the second core wire connector 5.

[0062] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the first plate 11 has a first through hole 111 and a clearance hole 112 for avoiding the limiting structure 31. The clearance hole 112 is adjacent to and connected to the first through hole 111. The second plate 12 has a second through hole 121 opposite to the first through hole 111 and a core wire through hole 122. The core wire through hole 122 is adjacent to and connected to the second through hole 121. The core wire through hole 122 extends to the edge of the second plate 12 and corresponds to the clearance hole 112.

[0063] The second core wire connector 5 can be assembled into the first through hole 111. The first plate 11 also has a clearance hole 112. The clearance hole 112 and the first through hole 111 are adjacent to each other and are connected. This allows the clearance hole 112 to avoid the limiting structure 31. It should be noted that the size of the clearance hole 112 is slightly larger than the size of the limiting structure 31 to reduce the risk of interference between the first plate 11 and the limiting structure 31, so that the second core wire connector 5 can be smoothly inserted into the first plate 11.

[0064] The second plate 12 has a second through hole 121 opposite to the first through hole 111, and the second core wire connector 5 passes through the first plate 11 and the second plate 12. The second plate 12 also has a core wire through hole 122, which is adjacent to the second through hole 121 and is connected to it. The core wire through hole 122 extends to the edge of the second plate 12, which helps to avoid the core wire connected to the second core wire connector 5, so that the second core wire connector 5 can be smoothly assembled into the second through hole 121, thereby achieving the effect of the second core wire connector 5 being smoothly passed through the first plate 11 and the second plate 12.

[0065] The core wire of the second core wire connector 5 and the limiting structure 31 of the second core wire connector 5 face the same direction. By setting the core wire through hole 122 and the avoidance hole 112 accordingly, the avoidance hole 112 can smoothly avoid the limiting structure 31, while the core wire through hole 122 can smoothly avoid the core wire 71, thereby completing the overall assembly of the second core wire connector 5.

[0066] Specifically, the third limiting part 51 of the second core wire connector 5 is first aligned with the clearance hole 112, and the core wire 71 is simultaneously aligned with the core wire through hole 122, so that the second core wire connector 5 can be smoothly inserted into the first plate 11 and the second plate 12. When the third limiting part 51 has completely passed through the clearance hole 112, the second core wire connector 5 is rotated by a certain angle, such as 80° or 90°, so that the third limiting part 51 rotates to abut against the first plate 11, and the fourth limiting part 52 rotates simultaneously to abut against the second plate 12, thereby achieving that the first plate 11 and the second plate 12 are sandwiched between the third limiting part 51 and the fourth limiting part 52, which is beneficial for the third limiting part 51 and the fourth limiting part 52 to restrict the first plate 11 and the second plate 12 from moving away from each other.

[0067] In some embodiments of this utility model, such as Figure 1 As shown, there are multiple second core wire connectors 5, which are arranged along a third direction, with the first direction, the second direction, and the third direction being perpendicular to each other.

[0068] The second core wire connector 5 can be configured in multiple ways, such as two or three. This application uses two second core wire connectors 5 as an example. The two second core wire connectors 5 are arranged along a third direction, and the core wires 71 of the left pull wire 8 and the right pull wire 9 are connected to the corresponding second core wire connectors 5. The first direction, the second direction, and the third direction are perpendicular to each other, that is, the X direction, the Y direction, and the Z direction are perpendicular.

[0069] When the vehicle brakes, the occupant pulls the parking brake handle, which moves the front pull cable 7. Since the core wire 71 of the front pull cable 7 is connected to the first core wire connector 2, and the first core wire connector 2 is connected to the fixing member 4 so that the stop block 3 is clamped between the balance block 1 and the fixing member 4, the front pull cable 7 can pull the first core wire connector 2 to move the fixing member 4 and the stop block 3, thereby moving the balance block 1.

[0070] Two second core wire connectors 5 are sequentially threaded along a third direction through the first plate 11 and the second plate 12 of the balance block 1. When the balance block 1 moves forward, it pulls the two second core wire connectors 5, thereby driving the core wires 71 of the corresponding left rear pull cable 8 and right rear pull cable 9. The core wires 71 of the left rear pull cable 8 and right rear pull cable 9 transmit force to the corresponding left and right wheel brakes, achieving the effect of braking the vehicle. By using multiple second core wire connectors 5, the left and right wheels can be braked synchronously during vehicle braking, reducing the risk of drifting and skidding.

[0071] As some embodiments of this application, such as Figure 1As shown, the vehicle cable core wire connector device 100 may include a cable box 10 and multiple return elements 20. Each return element 20 can be configured as a return spring. By assembling the multiple return elements 20 onto the corresponding front cable 7, left rear cable 8, and right rear cable 9, each cable can automatically return to its original position when the occupant releases the parking brake handle, thereby releasing the vehicle from braking. By assembling all components within the cable box 10, interference from the external environment on the vehicle cable core wire connector device 100 can be reduced, improving the operational stability of the vehicle cable core wire connector device 100.

[0072] The braking system according to this utility model includes the vehicle cable core wire connector device 100 of the above embodiment. By having at least one of the stop block 3 and the second core wire connector 5 have a limiting structure 31, the surfaces of the first plate 11 and the second plate 12 facing away from each other can abut against the limiting structure 31, thereby restricting the movement of the first plate 11 and the second plate 12 away from each other. This helps to reduce the risk of the second core wire connector 5 being pulled off due to the opening of the balance block 1 structure, thereby reducing the risk of braking system failure and improving the working reliability of the braking system. Furthermore, by improving the original balance block 1 structure, the braking system can continue to use the original process, only requiring an additional turning or upsetting process when machining the stop block 3, while the casting process is still used when machining the second core wire connector 5. The changes in the structure and process of the braking system are small, which helps to effectively improve the problem of the second core wire connector 5 being pulled off at a lower cost, reducing the time for handling vehicle abnormalities and improving the reliability of vehicle use.

[0073] The vehicle according to this utility model includes the braking system of the above embodiment. By having at least one of the stop block 3 and the second core wire connector 5 have a limiting structure 31, the surfaces of the first plate 11 and the second plate 12 facing away from each other can abut against the limiting structure 31, thereby restricting the movement of the first plate 11 and the second plate 12 away from each other. This helps to reduce the risk of the second core wire connector 5 being pulled off due to the opening of the balance block 1 structure, thereby reducing the risk of braking system failure and improving the working reliability of the braking system and the safety of vehicle use.
