Simultaneously, the first gasket can undergo compression deformation during the assembly of the brake rigid pipe and the pipe connector, and the second gasket can undergo compression deformation during the assembly of the brake rigid pipe and the brake hose, forming a highly reliable sealing structure between the brake rigid pipe and the pipe connector, and between the brake rigid pipe and the brake hose, thereby increasing the sealing reliability of the brake pipe assembly.

The second mating surface abuts against the bottom wall of the first mounting groove. Along the direction from the pipe joint to the brake hose, the second mating surface is inclined in a direction away from the axis of the first through hole.

[0011] In one possible implementation of this application, there is an angle A between the first mating surface and the axis of the first through hole, satisfying: 55°≤A≤65°; and / or, there is an angle B between the second mating surface and the axis of the first through hole, satisfying: 55°≤B≤65°.

[0037] The brake pipe assembly 100 provided in this application embodiment includes a pipe connector 1, a rigid pipe assembly 2, a brake hose 3, a first gasket 4, and a second gasket 5.

[0038] Specifically, the brake pipe assembly 100 is used in a vehicle. Brake fluid flows inside the brake pipe assembly 100. The brake fluid can provide lubrication for the vehicle's braking, avoiding excessive friction between the brake caliper 300 and the brake disc during vehicle braking, and thus avoiding affecting the service life of the brake caliper 300 and the brake disc.

[0039] like Figure 1 As shown, the length direction of pipe joint 1 (e.g.) Figure 1 The first mounting groove 11 is provided at both ends of the pipe connector 1 (shown in the first direction). The pipe connector 1 is provided with a first channel 12, which extends along the length of the pipe connector 1 and connects the two first mounting grooves 11. The rigid pipe assembly 2 includes multiple brake rigid pipes 21, which are arranged sequentially. The ends of two adjacent brake rigid pipes 21 that are closer to each other are respectively located in the two first mounting grooves 11 of the same pipe connector 1. By splitting the rigid pipe assembly 2 into multiple brake rigid pipes 21, the manufacturing cost and manufacturing difficulty of the rigid pipe assembly 2 can be reduced, and deformation of the rigid pipe assembly 2 during vehicle assembly can be avoided, thereby increasing the manufacturing reliability of the brake pipe assembly 100.

[0040] Meanwhile, the pipe connector 1 can be easily connected to the brake hard pipe 21, making the assembly of the brake pipe assembly 100 simpler and more convenient.

[0041] like Figure 1 As shown, the length direction of brake hose 3 (e.g.) Figure 1 One end of the brake hose 3 (as shown in the first direction) is provided with a second mounting groove 31, and a second channel 32 is provided inside the brake hose 3. The second channel 32 extends along the length direction of the brake hose 3 and communicates with the second mounting groove 31. The length direction of the rigid tube assembly 2 (as shown in the first direction) is as follows: Figure 1 A portion of the brake hard tube 21 at one end (shown in the first direction) is located in the second mounting groove 31, which facilitates the connection between the hard tube assembly 2 and the brake hose 3. The brake hose 3 can be connected to the brake caliper 300, and the brake hose 3 can transfer the brake fluid in the hard tube assembly 2 to the brake caliper 300 to achieve lubrication of the brake caliper 300.

[0042] like Figure 1 As shown, the first gasket 4 is disposed between the bottom wall of the first mounting groove 11 and the brake rigid pipe 21, which can prevent the brake rigid pipe 21 and / or the pipe joint 1 from cracking when the pipe joint 1 is assembled with the brake rigid pipe 21, prevent brake fluid from leaking from the crack, and increase the reliability of the assembly of the brake rigid pipe 21 and the pipe joint 1; the second gasket 5 is disposed between the bottom wall of the second mounting groove 31 and the brake rigid pipe 21, which can prevent the brake rigid pipe 21 and / or the brake hose 3 from cracking when the brake hose 3 is assembled with the brake rigid pipe 21, prevent brake fluid from leaking from the crack, and increase the reliability of the assembly of the brake rigid pipe 21 and the brake hose 3.

[0043] In addition, in this embodiment, the materials of the brake rigid pipe 21, brake flexible pipe 3 and pipe connector 1 are not limited, as long as the strength of the brake pipe assembly 100 can be guaranteed.

[0044] Additionally, it should be noted that in this embodiment, the first gasket 4 and the second gasket 5 are made of copper, the connector material of the brake hose 3 is steel, and the brake rigid pipe 21 is a double-layer copper welded pipe. Copper has a low hardness, and the first gasket 4 can be deformed by compression when the brake rigid pipe 21 is assembled with the pipe connector 1. The second gasket 5 can also be deformed by compression when the brake rigid pipe 21 is assembled with the brake hose 3, so that the brake rigid pipe 21 and the pipe connector 1 form a highly reliable sealing structure, thereby increasing the sealing reliability of the brake pipe assembly 100.

[0045] According to the brake pipe assembly 100 of this application, by placing a first gasket 4 between the bottom wall of the first mounting groove 11 of the pipe connector 1 and the brake rigid pipe 21, and placing a second gasket 5 between the bottom wall of the second mounting groove 31 of the brake hose 3 and the brake rigid pipe 21, cracking of the brake rigid pipe 21 and / or the pipe connector 1 can be avoided during the assembly of the pipe connector 1 and the brake rigid pipe 21, and cracking of the brake rigid pipe 21 and / or the brake hose 3 can be avoided during the assembly of the brake rigid pipe 21 and the brake hose 3, thus preventing brake fluid leakage from cracks and increasing the reliability of the assembly of the brake rigid pipe 21 and the brake hose 3. Simultaneously, the first gasket 4 and the second gasket 5 can undergo compression deformation during the assembly of the brake rigid pipe 21 and the pipe connector 1, respectively, forming a highly reliable sealing structure between the brake rigid pipe 21 and the pipe connector 1, and between the brake rigid pipe 21 and the brake hose 3, thereby increasing the sealing reliability of the brake pipe assembly 100.

[0046] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The first gasket 4 has a first through hole 41 to allow brake fluid to flow. At the end of the first through hole 41 furthest from the bottom wall of the first mounting groove 11, there is a first mating surface 42. The first mating surface 42 abuts against the axial end face of the brake hose 21. Along the direction from the brake hose 3 to the pipe connector 1, the first mating surface 42 is inclined away from the axis of the first through hole 41. The inclined first mating surface 42 can reduce the gap between the brake hose 21 and the first gasket 4 during assembly of the brake hose 21 and the pipe connector 1, achieving a linear seal between the brake hose 21 and the first gasket 4, and increasing the sealing effect during assembly of the brake hose 21 and the pipe connector 1.

[0047] In some embodiments of this application, reference is made to Figure 1 and Figure 2The bottom wall of the first mounting groove 11 is provided with a first protrusion 111, which can extend into the first through hole 41 to facilitate the positioning of the first gasket 4 and make the position of the first gasket 4 more reliable. Along the direction from the fixed end to the free end of the first protrusion 111, the peripheral wall of the first protrusion 111 is inclined towards the axis close to the first through hole 41 to avoid the first protrusion 111 from breaking during the assembly of the brake pipe assembly 100 and to avoid affecting the strength of the first protrusion 111.

[0048] Furthermore, referring to Figure 1 and Figure 2 A second mating surface 43 is provided at one end of the first through hole 41 near the bottom wall of the first mounting groove 11. The second mating surface 43 abuts against the bottom wall of the first mounting groove 11. Along the direction from the pipe joint 1 to the brake hose 3, the second mating surface 43 is inclined in a direction away from the axis of the first through hole 41. The inclined second mating surface 43 can reduce the gap between the bottom wall of the first mounting groove 11 and the first gasket 4 when the brake rigid pipe 21 is assembled with the pipe joint 1, thereby achieving a linear seal between the bottom wall of the first mounting groove 11 and the first gasket 4 and increasing the sealing effect when the brake rigid pipe 21 and the pipe joint 1 are assembled.

[0049] In some embodiments of this application, reference is made to Figure 1 and Figure 2 An angle A exists between the axis of the first mating surface 42 and the axis of the first through hole 41, satisfying 55°≤A≤65°. It can be understood that the angle A between the axis of the first mating surface 42 and the axis of the first through hole 41 can be 55°, 55.5°, 56°, 56.5°, 57°, 57.5°, 58°, 58.5°, 59°, 59.5°, 60°, 60.5°, 61°, 61.5°, 62.5°, 63°, 63.5°, 64°, 64.5°, or 65°. This allows for better fit with the axial end face of the brake hard tube 21 and prevents cracks from appearing when the first mating surface 42 mates with the brake hard tube 21, thus preventing brake fluid leakage.

[0050] In some embodiments of this application, reference is made to Figure 1 and Figure 2 An angle B exists between the second mating surface 43 and the axis of the first through hole 41, satisfying 55°≤B≤65°. It can be understood that the angle B between the second mating surface 43 and the axis of the first through hole 41 can be 55°, 55.5°, 56°, 56.5°, 57°, 57.5°, 58°, 58.5°, 59°, 59.5°, 60°, 60.5°, 61°, 61.5°, 62.5°, 63°, 63.5°, 64°, 64.5°, or 65°. This allows for better fit against the bottom wall of the first mounting groove 11 and prevents cracks from appearing when the first mating surface 42 mates with the first mounting groove 11, thus preventing brake fluid leakage.

[0051] In some embodiments of this application, reference is made to Figure 1 and Figure 3 The second gasket 5 has a second through hole 51 to allow brake fluid to flow. A third mating surface 52 is located at the end of the second through hole 51 furthest from the bottom wall of the second mounting groove 31. This third mating surface 52 abuts against the axial end face of the brake rigid tube 21. Along the direction from the brake hose 3 to the pipe connector 1, the third mating surface 52 is inclined away from the axis of the second through hole 51. This inclined third mating surface 52 reduces the gap between the brake rigid tube 21 and the second gasket 5 during assembly of the brake rigid tube 21 and the brake hose 3, achieving a linear seal between the brake rigid tube 21 and the second gasket 5, and increasing the sealing effect during assembly of the brake rigid tube 21 and the brake hose 3.

[0052] In some embodiments of this application, reference is made to Figure 1 and Figure 3 The bottom wall of the second mounting groove 31 is provided with a second protrusion 311, which can extend into the second through hole 51 to facilitate the positioning of the second gasket 5 and make the position of the second gasket 5 more reliable. Along the direction from the fixed end to the free end of the second protrusion 311, the peripheral wall of the second protrusion 311 is inclined towards the axis close to the second through hole 51 to avoid the second protrusion 311 from breaking during the assembly of the brake pipe assembly 100 and to avoid affecting the strength of the second protrusion 311.

[0053] Furthermore, referring to Figure 1 and Figure 3 A fourth mating surface 53 is provided at one end of the second through hole 51 near the bottom wall of the second mounting groove 31. The fourth mating surface 53 abuts against the bottom wall of the second mounting groove 31. Along the direction from the pipe joint 1 to the brake hose 3, the fourth mating surface 53 is inclined in a direction away from the axis of the second through hole 51. The inclined fourth mating surface 53 can reduce the gap between the bottom wall of the second mounting groove 31 and the second gasket 5 when the brake rigid pipe 21 and the brake hose 3 are assembled, thereby achieving a linear seal between the bottom wall of the second mounting groove 31 and the second gasket 5 and increasing the sealing effect when the brake rigid pipe 21 and the brake hose 3 are assembled.

[0054] In some embodiments of this application, reference is made to Figure 1 and Figure 3An angle C exists between the axis of the third mating surface 52 and the axis of the second through hole 51, satisfying 55°≤C≤65°. It can be understood that the angle C between the axis of the third mating surface 52 and the axis of the second through hole 51 can be 55°, 55.5°, 56°, 56.5°, 57°, 57.5°, 58°, 58.5°, 59°, 59.5°, 60°, 60.5°, 61°, 61.5°, 62.5°, 63°, 63.5°, 64°, 64.5°, or 65°. This allows for better fit with the axial end face of the brake hard tube 21 and prevents cracks from appearing when the third mating surface 52 mates with the brake hard tube 21, thus preventing brake fluid leakage.

[0055] In some embodiments of this application, reference is made to Figure 1 and Figure 3 An angle D exists between the fourth mating surface 53 and the axis of the second through hole 51, satisfying 55°≤D≤65°. It can be understood that the angle D between the fourth mating surface 53 and the axis of the second through hole 51 can be 55°, 55.5°, 56°, 56.5°, 57°, 57.5°, 58°, 58.5°, 59°, 59.5°, 60°, 60.5°, 61°, 61.5°, 62.5°, 63°, 63.5°, 64°, 64.5°, or 65°. This allows for better fit against the bottom wall of the second mounting groove 31 and prevents cracks from appearing when the fourth mating surface 53 mates with the second mounting groove 31, thus preventing brake fluid leakage.

[0056] This application also provides a vehicle including a brake controller 200 and the aforementioned brake pipe assembly 100. The brake controller 200 is connected to the end of the rigid pipe assembly 2 away from the brake hose 3, thereby enabling the brake controller 200 to communicate with the brake pipe assembly 100 and the brake caliper 300, and enabling brake fluid to flow from the brake controller 200 to the brake caliper 300.

[0057] In this embodiment, the brake controller 200 can be an ESC (Electronic Stability Controller) or a One Box (intelligent booster). ESC is a further extension of the functions of the Anti-lock Braking System (ABS) and Traction Control System (TCS). By adding yaw rate sensors, lateral acceleration sensors, and steering wheel angle sensors during vehicle steering, it precisely controls the driving and braking forces of the wheels, ensuring vehicle stability under various driving conditions. One Box typically refers to a system that integrates the braking system's power supply device (such as a booster) with the control device (such as an ESC module) into a single component. This integrated design not only simplifies the structure but also improves efficiency.

[0058] According to the vehicle of this application, by placing the first gasket 4 between the bottom wall of the first mounting groove 11 of the pipe connector 1 and the brake rigid pipe 21, and placing the second gasket 5 between the bottom wall of the second mounting groove 31 of the brake hose 3 and the brake rigid pipe 21, cracking of the brake rigid pipe 21 and / or the pipe connector 1 can be avoided during the assembly of the pipe connector 1 and the brake rigid pipe 21, and cracking of the brake rigid pipe 21 and / or the brake hose 3 can be avoided during the assembly of the brake rigid pipe 21 and the brake hose 3, thus preventing brake fluid leakage from cracks and increasing the reliability of the assembly of the brake rigid pipe 21 and the brake hose 3. Simultaneously, the first gasket 4 and the second gasket 5 can undergo compression deformation during the assembly of the brake rigid pipe 21 and the pipe connector 1, respectively, resulting in a highly reliable sealing structure between the brake rigid pipe 21 and the pipe connector 1, and between the brake rigid pipe 21 and the brake hose 3, thereby increasing the sealing reliability of the brake pipe assembly 100.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
