Description

Technical Field

[0001] This utility model belongs to the technical field of new braking system plugs for new energy vehicles, specifically relating to a new type of braking system plug for new energy vehicles. Background Technology

[0002] With the rise of new energy vehicles in China, the traditional automobile market has been encroached upon by new energy vehicles. Currently, the market share of new energy vehicles has reached 49%. In order to better adapt to the intelligent development of new energy vehicles, the traditional hydraulic mechanical braking system can no longer meet the needs of new energy vehicles. Instead, a brand-new braking system with intelligent chips has emerged to meet the needs of intelligent driving.

[0003] The emergence of a new One-box brake-by-wire system (integrated braking system) in China now uses electronic chip-based motor assistance to replace vacuum assistance, thus solving the problem of the lack of a stable vacuum source in new energy vehicles.

[0004] In traditional systems, the plug and solenoid valve are usually separate modules connected by independent hydraulic lines. This decentralized design results in a large system size and increased hydraulic line length. In contrast, the One-box braking system integrates modules such as the electronic booster, ESC, and brake master cylinder into a single unit. Under space constraints, it is necessary to meet the integrated design requirements between the plug and the solenoid valve body.

[0005] In view of this, the present invention provides a new type of brake system plug for new energy vehicles to meet market demand. Utility Model Content

At the same time, a protrusion that matches the groove II extends radially along the inner wall of the opening at one end, and a locking part that matches the locking block is also radially opened along the inner wall of the cylindrical elastic layer.

[0013] As a preferred embodiment of the novel braking system plug for new energy vehicles according to this utility model, an abutment portion for cooperating with the valve block in the valve body extends radially along the inner wall of the opening at the other end of the elastic layer.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model relates to a novel brake system plug for new energy vehicles, such as... Figures 1-4 As shown, it includes a skeleton 1 made of metal materials such as stainless steel and aluminum alloy, and an elastic layer 2 made of EPDM rubber that is vulcanized and connected to the skeleton 1. The skeleton 1 can be pressed into the pipeline of the solenoid valve body end face in the One-box braking system, so that the elastic layer 2 extends into the solenoid valve body and cooperates with the valve block in the valve body, thereby realizing the opening and closing of the brake fluid pipeline.

[0028] Specifically, such as Figure 5As shown, the skeleton 1 is generally in the shape of an inverted "T", including a circular bottom wall 11 and a columnar side wall 12 axially integrated with one end face of the bottom wall 11. The other end face of the bottom wall 11 is axially provided with a liquid inlet hole 13 that passes through the side wall 12. The side wall 12 is radially provided with a groove 15 surrounding the side wall 12. The side wall 12 is also integrally connected with a surrounding locking block 16. The longitudinal section of the locking block 16 is a right trapezoid with the inclined surface of the trapezoid facing upward to facilitate the fitting of the elastic layer 2. The elastic layer 2 is a cylindrical structure with both ends connected. At least one annular sealing part 24 is formed on its periphery. A protrusion 22 that matches the groove 15 extends radially along the inner wall of the opening at one end. A locking part 23 that matches the locking block 16 is also radially provided along the inner wall of the cylindrical elastic layer 2. When the elastic layer 2 is fitted onto the side wall 12, the locking block 16 can engage in the engaging part 23, and the protrusion 3 22 engages in the groove 2 15, thus forming a double-layer engagement, which improves the axial connection force and also increases the vulcanized surface contact to improve the adhesion strength.

[0029] Preferably, the elastic layer 2 has two sealing parts 24 formed on its periphery. The sealing part 24 has an arc-shaped cross section. When the skeleton 1 is pressed into the valve body end face, the sealing part 24 can abut against the periphery of the valve body to form an interference fit connection, so as to prevent brake fluid from overflowing from the periphery of the elastic layer 2 and improve the sealing performance.

[0030] Furthermore, an abutment portion 21 extends radially along the inner wall of the opening at the other end of the elastic layer 2, which abuts against the end face of the valve block inside the valve body. In its natural state, under the elasticity of the spring, the abutment portion 21 is always in close contact with the end face of the valve block inside the valve body, thereby achieving the sealing and blocking of the brake fluid pipeline. When energized, the solenoid valve opens, the valve block moves to compress the spring, the valve block moves away from the abutment portion 21, forming a passage, and the brake fluid enters from the reservoir through the pipeline through the inlet hole 13, ultimately achieving vehicle braking.

[0031] To improve the radial connection performance between the abutment part 21 and the side wall 12, an arc-shaped groove 14 surrounding the liquid inlet hole 13 is provided on the top surface of the side wall 12. The abutment part 21 has an annular arc-shaped protrusion 211 that matches the groove 14 on the end face of the skeleton 1. After the elastic layer 2 is connected to the skeleton 1, the outer edge of the protrusion 211 is vulcanized with the inner wall of the groove 14, which improves the adhesion strength. At the same time, the radial support is improved by the cooperation between the protrusion and the groove, so as to prevent the abutment part 21 from detaching from the end face of the side wall 12 and reducing the sealing performance.

[0032] Furthermore, in order to improve the sealing performance between the contact part 21 and the valve body when they come into contact, an arc-shaped protrusion 212 surrounding the inlet hole 13 is formed on the end face of the contact part 21 relative to the valve block inside the valve body. An arc-shaped annular groove with a cross section that matches the protrusion 212 can be opened on the end face of the valve body. When the two are pressed together, the protrusion 212 can form a barrier layer at the opening end face of the inlet hole 13 to effectively prevent the brake fluid in the inlet hole 13 from overflowing from the contact point.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
