[0024] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0025] Example:
[0026] The present invention provides a brake-by-wire fluid reservoir with leakage protection. The design of the leakage protection mechanism improves the connection between the tank body and the brake-by-wire cylinder. This reinforces the connection to reduce leakage risks while providing leakage protection. This effectively prevents the brake system from being hit or knocked during driving, which can easily cause the connection between the brake cylinder and the fluid reservoir to loosen, thereby causing leakage from the fluid reservoir outlet, which could contaminate the vehicle body and waste resources. This addresses the problems raised in the aforementioned background art.
[0027] See also Figure 1-Figure 7, the utility model provides a technical solution:
[0028] A wire-controlled brake fluid reservoir with leakage protection includes a fluid reservoir body 1, wherein the fluid reservoir body 1 includes a tank body 2, the tank body 2 is installed on the top surface of a wire-controlled brake cylinder through a leakage protection mechanism 3, and the leakage protection mechanism 3 is composed of a casing assembly 4, a tank body assembly assembly 5, and a cylinder body assembly assembly 6. The design of the leakage protection mechanism 3 can improve the connection between the tank body 2 and the wire-controlled brake cylinder, strengthen the connection to reduce the risk of leakage, and have the function of leakage protection, effectively preventing the brake system from being hit or bumped during driving, which is very likely to cause the connection between the brake cylinder and the fluid reservoir to become loose, thereby causing leakage at the fluid reservoir oil outlet, resulting in pollution of the vehicle body and waste of resources. In addition, the structural components of the leakage protection mechanism 3 are simple, the improvement cost is low, it is economical and effective, and the assembly technology is low in difficulty and easy to use.
[0029] Among them, the protective tube assembly 4 includes an outer liquid protection cylinder body 41, an inner liquid leakage cylinder body 42 is fixedly installed inside the outer liquid protection cylinder body 41, a liquid cavity 411 is provided between the outer liquid protection cylinder body 41 and the inner liquid leakage cylinder body 42, a liquid leakage hollow section 421 is provided near the middle of the inner liquid leakage cylinder body 42, and a plurality of groups of annular limiting arc grooves 422 are opened around the inner wall of the inner liquid leakage cylinder body 42. When the brake system is damaged by a strong impact and the connection between the oil outlet of the tank body 2 and the brake cylinder becomes loose, the oil leaked from the oil outlet will pass through the liquid leakage hollow section 421 into the interior of the liquid cavity 411, and the outer liquid protection cylinder body 41 is used to protect and collect the leaked liquid. The design of the outer liquid protection cylinder body 41 and the inner liquid leakage cylinder body 42 can enhance the structural stability of the connection between the oil outlet of the tank body 2 and the brake cylinder.
[0030] In addition, in this embodiment, please refer to Figure 4 The top and bottom ends of the outer liquid protection cylinder 41 are respectively fixedly installed with an upper sealing cylinder cover 43 and a lower sealing cylinder cover 44. The upper and lower ends of the inner liquid leakage cylinder 42 are respectively fixedly connected to the upper and lower sealing cylinder covers 43 and the lower sealing cylinder covers 44. The upper and lower sealing cylinder covers 43 and the lower sealing cylinder covers 44 are penetrated with assembly openings 45 that are compatible with the inner liquid leakage cylinder 42. The design of the upper and lower sealing cylinder covers 43 and the lower sealing cylinder covers 44 can seal the upper and lower ends of the outer liquid protection cylinder 41 to prevent leakage. At the same time, the design of the assembly openings 45 that are compatible with the inner liquid leakage cylinder 42 facilitates the smooth assembly of the tank body assembly component 5 and the cylinder body assembly component 6.
[0031] In addition, in this embodiment, please refer to Figure 5, a wire through-hole 431 is provided on the upper sealing cylinder cover 43 near the assembly opening 45, and a water immersion probe 441 is fixedly installed on the top surface of the lower sealing cylinder cover 44 near the assembly opening 45. The water immersion probe 441 is electrically connected to the external water immersion sensor through a connecting wire, and the connecting wire passes through the inside of the wire through-hole 431. The design of the water immersion probe 441 can monitor the liquid in the liquid cavity 411. When there is liquid in the liquid cavity 411 and it contacts these water immersion probes 441, a circuit is closed, thereby triggering the external water immersion sensor, which is convenient for timely handling of the leakage and avoiding the influence of a large amount of leakage on the automobile braking system. At the same time, the design of the wire through-hole 431 facilitates the routing of the connecting wire to realize the electrical connection between the water immersion probe 441 and the external water immersion sensor;
[0032] In addition, in this embodiment, please refer to Figure 6 and Figure 7 The outer surfaces of the upper and lower assembly sleeves 52 and 62 are respectively fixedly mounted with upper and lower limit arc blocks 521 and 621 corresponding to several groups of annular limit arc grooves 422. The upper and lower assembly sleeves 52 and 62 and the upper and lower limit arc blocks 521 and 621 corresponding to several groups of annular limit arc grooves 422 not only facilitate the accurate assembly of the tank body oil outlet pipe 51 and the cylinder body oil inlet pipe 61 while preventing self-rotation, but also contribute to the structural stability of the connection between the tank body oil outlet pipe 51 and the cylinder body oil inlet pipe 61.
[0033] In addition, in this embodiment, please refer to Figure 6 and Figure 7 , an upper positioning arc block 522 is fixedly installed between the top end of the outer surface of the upper assembly sleeve 52 and the two adjacent groups of upper limit arc blocks 521, and a lower positioning arc block 622 is fixedly installed between the bottom end of the outer surface of the lower assembly sleeve 62 and the two adjacent groups of lower limit arc blocks 621. The design of the upper positioning arc block 522 and the lower positioning arc block 622 facilitates the positioning of the assembled tank body oil outlet pipe 51 and the cylinder body oil inlet pipe 61, ensuring that the connection between the tank body oil outlet pipe 51 and the cylinder body oil inlet pipe 61 corresponds to the leaking hollow section 421;
[0034] In this embodiment, the implementation scenario is specifically as follows: during actual use, the upper assembly sleeve 52 and the lower assembly sleeve 62 can be aligned and inserted into the interior of the assembly openings 45 on the upper sealing cylinder cover 43 and the lower sealing cylinder cover 44 that are compatible with the inner leakage cylinder 42, and then the upper assembly sleeve 52 and the lower assembly sleeve 62 are introduced from the two ends of the inner leakage cylinder 42 and approach each other until the tank body oil outlet pipe 51 away from the end of the tank body 2 is inserted into the interior of the cylinder body oil inlet pipe 61, and at the same time, the upper positioning arc block 522 is tightly attached to the upper sealing cylinder cover 43, and the lower positioning arc block 622 is tightly attached to the lower sealing cylinder cover 44 to complete the rapid assembly. During the operation of the brake cylinder, the tank body 2 supplies fluid to the cylinder through the leakage protection mechanism 3. When the brake system is subjected to a strong impact and damages the oil outlet of the tank body 2 and the brake When the cylinder connection becomes loose, the oil leaking from the oil outlet will pass through the leakage hollow section 421 into the interior of the liquid cavity 411, and the outer liquid protection cylinder 41 will be used to protect and collect the leaked liquid. The design of the water immersion probe 441 can monitor the liquid in the liquid cavity 411. When there is liquid in the liquid cavity 411 and it contacts these water immersion probes 441, a circuit will be closed, thereby triggering the external water immersion sensor, which is convenient for timely handling of the leakage and avoids the impact of large amounts of leakage on the automobile braking system. The overall system has a leakage protection function, which effectively prevents the braking system from being hit or bumped during driving, which can easily cause the connection between the brake cylinder and the liquid storage tank to loosen, thereby causing leakage at the oil outlet of the liquid storage tank, resulting in pollution of the vehicle body and waste of resources.
