[0002] The brake line of new energy vehicles is a key component in the braking system. When the brake pedal is pressed, it is responsible for transferring the braking medium to the brake shoe or brake caliper, thereby generating braking force, ensuring that the car can brake effectively at any time and protecting the driver's driving safety.

[0003] However, the existing brake lines for new energy vehicles have the following defects: for example, under normal circumstances, the brake lines may age with the increase of usage time, or the brake line wall may rupture due to external impact, and the brake lines need to be replaced in time. When replacing the brake lines, it is usually necessary to drain all the brake fluid in the brake lines before replacing the brake lines, and the operation process is cumbersome. Summary of the invention

[0004] The purpose of the present application is to solve the problem that when replacing a brake line, the brake fluid in the brake line needs to be completely drained before replacement can be performed, and the operation process is cumbersome.

[0009] Further preferably, a sleeve internal thread is provided on the right outer wall of the movable sleeve, the diameter of the sleeve internal thread corresponds to the diameter of the sleeve external thread, and outer walls of the two outer sleeves are provided with external sealing grooves.

[0010] Further preferably, the outer wall of the main body is fixedly connected with a wave crest, and the number of the wave crests is multiple, and the material of the main body is nylon rubber material.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] (1) In the initial state, the multiple sections of the main body are connected together, and the main body is filled with brake fluid. At the same time, the two springs are in a contracted state, so that the two sealing plates are respectively fitted with the outer walls of the two center columns, and an inner sealing ring is installed inside the fitting part, so that each section of the main body is in a closed state.

In the existing brake pipe, under normal circumstances, the brake pipe may age with the increase of service time, or the brake pipe wall may be broken due to external impact, and the brake pipe needs to be replaced in time. When replacing the brake pipe, it is usually necessary to drain all the brake fluid in the brake pipe before replacing the brake pipe. The operation process is cumbersome. In the process of removing the damaged brake pipe, it is not necessary to drain all the brake fluid, and there will be no oil leakage at the joints of the other two main bodies connected to the two ends of the main body, and the operation process is convenient and fast.

[0013] (2) When two sections of the main body are docked, the outer sleeve on the right end of the original main body is docked with the outer sleeve on the left end of the other section of the main body, and before docking, a sealing ring is installed inside the outer sealing groove opened on the outer wall of the outer sleeve on the right side of the original main body. Then, the movable sleeve arranged on the outer wall of the outer sleeve on the right side of the original main body is rotated to move the movable sleeve away from the original main body. When the movable sleeve moves, the sleeve internal thread opened on its inner wall is engaged with the sleeve external thread opened on the outer wall of the outer sleeve on the left side of the other section. The outer sleeve on the left side of the other section of the main body will move toward the direction of the original main body as the movable sleeve rotates, thereby tightly connecting the two sections of the main body.

[0026] like Figure 1-7 A brake pipeline for a new energy vehicle shown in the figure comprises a main body 1, inner sleeves 2 are installed inside both ends of the main body 1, the inner wall of the inner sleeve 2 is fixedly connected with a connecting block 3, and there are multiple connecting blocks 3, a center column 4 is arranged inside the inner sleeve 2, the outer wall of the center column 4 is fixedly connected with the outer wall of the other end of the multiple connecting blocks 3, a spring groove 5 is opened on the outer wall of the center column 4, a spring 6 is fixedly connected to the inner wall of the spring groove 5, a telescopic block 7 is fixedly connected to the other end of the spring 6, a sealing plate 8 is fixedly connected to the other end of the telescopic block 7, an outer sleeve 9 is fixedly connected to the outer wall of the inner sleeve 2 away from the main body 1, an inner sealing groove 10 is opened on the surface where the sealing plate 8 and the inner sleeve 2 are in contact, and an inner sealing ring 11 is installed inside the inner sealing groove 10.

[0027] In the initial state, multiple sections of the main body 1 are connected together, and the main body 1 is filled with brake fluid. At the same time, the two springs 6 are in a contracted state, so that the two sealing plates 8 are respectively fitted with the outer walls of the two center columns 4, and an inner sealing ring 11 is installed inside the fitting part, so that each section of the main body 1 is in a closed state. When the main body 1 is damaged and needs to be replaced, it is only necessary to separate the two ends of the damaged main body 1 from the main body 1 connected at both ends. In the process of removing the damaged brake pipe, there is no need to drain all the brake fluid, and there will be no oil leakage at the joints of the other two main bodies 1 connected to the two ends of the main body 1, and the operation process is convenient and fast.

[0028] When the driver steps on the brake pedal to brake, the brake fluid inside the brake cylinder will generate pressure, and the brake fluid will flow into the brake pipe from the gap between the center column 4 at the right end of the brake pipe and the inner sleeve 2. When the brake fluid flows, it will first push the right sealing plate 8 toward the inside of the main body 1, thereby forming a passage on the right side of the main body 1, and by the same principle, the left sealing plate 8 moves away from the main body 1, so that a passage is formed in the entire brake pipe, and the pressure is transmitted to the brakes of each wheel through the hydraulic pipeline, thereby achieving vehicle braking. After releasing the brake, part of the hydraulic oil inside the main body 1 will flow back during the process of the two sealing plates 8 returning to their original positions. The next time the brake pedal is stepped on again, the vehicle braking is achieved by the same principle.

[0029] The two spring grooves 5 are opened in the same direction, the right sealing plate 8 is located inside the right end of the main body 1, and the left sealing plate 8 is located inside the left outer sleeve 9. The outer walls of the two inner sleeves 2 are provided with clamp grooves 12, and the outer walls of both ends of the main body 1 are provided with clamps 13. The positions of the clamps 13 and the clamp grooves 12 correspond to each other, so that the two ends of the main body 1 can be firmly connected with the two inner sleeves 2 without detachment.

[0030] A sleeve external thread 14 is provided on the outer wall of the left outer sleeve 9, a movable groove 15 is provided on the outer wall of the right outer sleeve 9, a movable thread 16 is provided on the inner wall of the movable groove 15, a movable sleeve 17 is installed inside the movable groove 15, a positioning thread 18 is provided on the left outer wall of the movable sleeve 17, the positioning thread 18 is meshed with the movable thread 16, a sleeve internal thread 19 is provided on the right outer wall of the movable sleeve 17, the diameter of the sleeve internal thread 19 corresponds to the diameter of the sleeve external thread 14, and the outer walls of the two outer sleeves 9 are provided with external sealing grooves 20.

[0031] When installing a new main body 1, the outer sleeve 9 on the right end of the new main body 1 is docked with the outer sleeve 9 on the left side of the other main body 1, and before docking, a sealing ring is installed inside the outer sealing groove 20 opened on the outer wall of the outer sleeve 9 on the right side of the new main body 1, and then the moving sleeve 17 set on the outer wall of the outer sleeve 9 on the right side of the new main body 1 is rotated to move the moving sleeve 17 away from the new main body 1. When the moving sleeve 17 moves, the sleeve internal thread 19 opened on its inner wall is engaged with the sleeve external thread 14 opened on the outer wall of the outer sleeve 9 on the left side of the other main body 1. The outer sleeve 9 on the left side of the other main body 1 will move toward the direction of the new main body 1 as the moving sleeve 17 rotates, thereby making the two main bodies 1 tightly connected.

[0032] The outer wall of the main body 1 is fixedly connected with a wave crest 21, and there are multiple wave crests 21. The wave crests can play a role in buffering and resisting pressure. The material of the main body 1 is nylon rubber material.

[0033] Working principle: In the initial state, multiple sections of the main body 1 are connected together, and the main body 1 is filled with brake fluid, and the two springs 6 are in a contracted state, so that the two sealing plates 8 are respectively fitted with the outer walls of the two center columns 4, and an inner sealing ring 11 is installed inside the fitting part, so that each section of the main body 1 is in a closed state. When the main body 1 is damaged and needs to be replaced, it is only necessary to separate the two ends of the damaged main body 1 from the main body 1 connected at both ends. In the process of removing the damaged brake pipe, there is no need to drain all the brake fluid, and there will be no oil leakage at the joints of the other two main bodies 1 connected to the two ends of the main body 1. The operation process is convenient and fast. When installing a new main body 1, the outer sleeve 9 on the right end of the new main body 1 is docked with the outer sleeve 9 on the left side of the other section of the main body 1, and a sealing ring is installed inside the outer sealing groove 20 opened on the outer wall of the outer sleeve 9 on the right side of the new main body 1 before docking, and then the outer sleeve 9 on the right side of the new main body 1 is rotated. The movable sleeve 17 arranged on the outer wall of the sleeve 9 makes the movable sleeve 17 move in the direction away from the new main body 1. When the movable sleeve 17 moves, the sleeve internal thread 19 provided on its inner wall is meshed with the sleeve external thread 14 provided on the outer wall of the outer sleeve 9 on the left side of the other section. The outer sleeve 9 on the left side of the other section of the main body 1 will move in the direction of the new main body 1 as the movable sleeve 17 rotates, so that the two sections of the main body 1 are tightly connected. When the driver steps on the brake pedal to brake, the brake fluid inside the brake cylinder will generate pressure, and the brake fluid will flow into the brake line from the gap between the center column 4 at the right end of the brake line and the inner sleeve 2. When the brake fluid flows, it will first push the right side sealing plate 8 toward the inside of the main body 1, so that a passage is formed on the right side of the main body 1, and by the same principle, the left side sealing plate 8 moves in the direction away from the main body 1, so that a passage is formed in the entire brake line, and the pressure is transmitted to the brakes of each wheel through the hydraulic line, thereby achieving the braking of the vehicle.
