Description

Technical Field

[0001] This application relates to the field of automotive brake line technology, and more specifically, to an anti-burst reinforcement structure for automotive brake lines. Background Technology

[0002] Brake lines are a key component of a car's braking system. They are mainly used to transmit brake fluid and transfer the pressure generated when the driver presses the brake pedal to the brake calipers or brake drums on the wheels, thereby slowing down or stopping the vehicle.

[0003] In related technologies, after brake fluid is introduced into the brake line and braking occurs, a peak back pressure will appear. The back pressure will instantly increase and act on the brake line, which can easily cause the brake line to burst. In order to improve the heat dissipation performance of the brake line, for example, the patent with publication number CN209800897U provides a heat dissipation and burst prevention brake line. This device has the characteristics of compact structure, firm connection, high safety and reliability, good heat dissipation effect, burst prevention and long service life. It solves the problem of potential safety hazards in vehicle operation, avoids brake failure, improves the safety of vehicle operation, and alleviates the impact stress and continuous temperature rise on the brake line during the reciprocating process of oil inlet and outlet.

[0004] Although the existing technical solutions mentioned above utilize the honeycomb structure of the cross-section of the carbon fiber hollow water-passing tube layer, allowing cooling water to circulate through the oil pipe joints at both ends of the brake oil pipe body and the carbon fiber hollow water-passing tube layer to effectively dissipate heat and cool the brake oil pipe body, the brake oil pipe body is directly sleeved between the oil pipe transition tube body and the oil-passing tube sleeve, resulting in an unstable connection. This can lead to leakage or even bursting of the brake oil pipe body. Furthermore, if a fastening structure is added to the outside of the brake oil pipe body, the end of the outer rubber tube layer is prone to bending, causing the end of the carbon fiber hollow water-passing tube layer to close, reducing the water-passing effect of the carbon fiber hollow water-passing tube layer, and thus reducing the heat dissipation effect of the brake oil pipe body.

[0005] In view of this, we propose a burst-proof reinforcement structure for automotive brake lines. Utility Model Content

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 This application discloses an anti-burst reinforcement structure for automotive brake pipes, including a brake pipe body 1, with sleeves 2 at both ends of the brake pipe body 1, and reinforcement components 3 on the outer sides of the two sleeves 2. The two reinforcement components 3 are used to reinforce the connection between the two sleeves 2 and the brake pipe body 1, and threaded pipe joints 4 are provided on the inner sides of the two sleeves 2.

[0033] Two sleeves 2 are connected to the brake tube body 1 through two reinforcing components 3. The two sleeves 2 are also connected to two threaded pipe joints 4, thereby connecting the brake tube body 1 to the two threaded pipe joints 4. The connection between the brake tube body 1 and the threaded pipe joints 4 is reinforced by the sleeves 2 and the reinforcing components 3, thereby preventing the brake tube body 1 from leaking fluid and thus achieving the effect of preventing the brake tube body 1 from bursting.

[0034] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The brake hose body 1 includes an inner rubber hose layer 11 and an outer rubber hose layer 12. A water-passing layer 13 is provided between the inner rubber hose layer 11 and the outer rubber hose layer 12. A water-passing port 21 is opened on the side of each of the two hose sleeves 2 that are close to each other. A connecting pipe 22 is fixedly installed on each of the two hose sleeves 2 corresponding to the water-passing port 21. The ends of the two hose sleeves 2 that are close to each other are located inside the water-passing layer 13. Each of the two reinforcing components 3 includes a fixing protrusion ring 31. The inner side of each of the two fixing protrusion rings 31 is fixedly installed on the outer side of the corresponding hose sleeve 2. The ends of the two fixing protrusion rings 31 that are close to each other are fixedly installed on the side of each hose sleeve 2. There are two inclined rings 32, and two fixing rings 33 are provided on the inner side of each inclined ring 32. The two inclined rings 32 and the two fixing rings 33 are fixedly set by corresponding fixing components 34. The outer side of the fixing protruding ring 31 has two fixing holes A311 corresponding to the two fixing components 34, and the outer side of the fixing ring 33 has two fixing holes B331 corresponding to the two fixing components 34. Both fixing components 34 include bolts 341. Both bolts 341 pass through the corresponding fixing holes A311 and B331. Nuts 342 are threaded on the outer side of both bolts 341.

[0035] During installation, first, place the two fixing rings 33 on the outside of the outer rubber tube layer 12. Then, insert the two tube sleeves 2, with their ends close to each other, into the water passage layer 13, so that the inner sides of the two water inlets 21 contact the outer sides of the inner rubber tube layer 11. This connects the water passage layer 13 with the water inlets 21 and the connecting pipe 22, allowing connection to external water supply equipment to supply water to the water passage layer 13. Then, move the corresponding fixing rings 33 closer to the inside of the inclined rings 32 to tighten the fixing rings 33. Apply the outer rubber tube layer 12 and the inclined ring 32, then pass the corresponding two bolts 341 through the corresponding fixing port A311 and fixing port B331, and connect the two nuts 342 to the two bolts 341 by thread, so that the fixing ring 33 and the inclined ring 32 are fixed and tightened, thereby fixing and tightening the brake tube body 1 and the tube sleeve 2, strengthening the connection between the brake tube body 1 and the tube sleeve 2, preventing leakage of liquid from the water layer 13 and the inner side of the inner rubber tube layer 11, and thus preventing the brake tube body 1 from bursting.

[0036] Reference Figure 1 and Figure 2 Both threaded pipe joints 4 have beveled surfaces B41 and threaded surfaces B42 on their outer sides. The sides of the two beveled surfaces B41 that are close to each other are located on the inner side of the inner rubber tube layer 11. Both pipe sleeves 2 have beveled surfaces A23 and threaded surfaces A24 on their inner sides. Beveled surfaces B41 and A23 cooperate with each other, and threaded surfaces B42 and A24 cooperate with each other.

[0037] After connecting the two sleeves 2 to the brake tube body 1, insert the two threaded pipe joints 4 into the inside of the sleeves 2, so that the corresponding inclined surface B41 mates with the corresponding water inlet 21, and fix the inner rubber tube layer 11 between the inclined surface B41 and the water inlet 21. By mate between the threaded surface A24 and the threaded surface B42, the threaded pipe joints 4 and the sleeves 2 are fixed, so that the brake tube body 1, the sleeves 2 and the threaded pipe joints 4 are tightly fixed to prevent leakage.

[0038] In summary, when using the anti-burst reinforcement structure for automotive brake pipes disclosed in this application, first, two fixing rings 33 are fitted onto the outside of the outer rubber tube layer 12. Then, the ends of the two sleeves 2 that are close to each other are inserted into the water-passing layer 13, so that the inner sides of the two water inlets 21 are in contact with the outer sides of the inner rubber tube layer 11, making the water-passing layer 13 connected to the water inlets 21 and the connecting pipe 22. Through the connecting pipe 22, an external water supply device can be connected to supply water to the water-passing layer 13. Then, the corresponding fixing rings 33 are moved closer to the inner side of the inclined ring 32, so that the fixing rings 33 are tightly attached to the outer rubber tube layer 12 and the inclined ring 32. Finally, the corresponding two bolts 341 are passed through the corresponding fixing ports A311 and fixed. Port B331 is connected to two nuts 342 and two bolts 341 by threads, which fixes the retaining ring 33 and the inclined ring 32, thereby fixing the brake tube body 1 and the sleeve 2. Then, two threaded pipe joints 4 are inserted into the inside of the sleeve 2, so that the corresponding inclined surface B41 and the corresponding water inlet 21 are engaged, fixing the inner rubber tube layer 11 between the inclined surface B41 and the water inlet 21. The threaded surface A24 and the threaded surface B42 are engaged to complete the fixing of the threaded pipe joint 4 and the sleeve 2, thereby fixing the brake tube body 1, the sleeve 2 and the threaded pipe joint 4 tightly, which can prevent the water inlet layer 13 and the inner side of the inner rubber tube layer 11 from leaking, and thus prevent the brake tube body 1 from bursting.
