Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, in particular to a novel automobile brake hose. Background Art

[0002] The working principle of the automobile brake hose is to transfer the braking medium, usually brake fluid, in the automobile braking system, thereby transferring the braking force to the brakes of each wheel to achieve the purpose of deceleration or stopping. When the driver steps on the brake pedal, the booster will apply pressure to the brake master cylinder, pushing the brake fluid in the brake master cylinder to be transported to the brake cylinder of each wheel through the brake pipeline. The hydraulic pressure will push the piston to move, and then the brake shoe or brake caliper connected to the wheel will clamp the brake disc or brake drum, generating strong friction. This friction converts the kinetic energy of the vehicle into heat energy, thereby slowing down the speed until the vehicle stops. The hose in the brake system is usually made of rubber material, and its appearance needs to be checked regularly for cracks, oil leakage, bulging, etc.

[0003] At the same time, the patent specification with application number CN202223017577.2 discloses an automobile brake hose assembly, including a connector and a hose, a fixing ring, four clamping blocks are installed on the outside of the fixing ring, and a plurality of fixing strips and a fixing groove are fixedly connected inside the fixing ring. The fixing groove is opened at one end of the connector, and four insertion grooves are opened on one side of the fixing groove. The bottom of the four insertion grooves is opened with a rotating groove. The automobile brake hose assembly is achieved by sleeved a fixing ring on the outside of the hose, and pushing the fixing ring into the inside of the fixing groove. The hose is limited and fixed by the fixing strip inside the fixing ring, and the fixing ring is rotated to rotate the clamping block into the rotating groove, thereby changing the fixed installation between the hose and the connector into a movable installation.

[0004] During use, when the existing automobile brake hose is driven on a bumpy road, the brake hose is installed movably. Under bad road conditions, the automobile will bump. When the automobile turns, the brake hose will rotate slightly. Over time, the automobile brake hose will loosen and fall off, the brake oil will leak out, and the liquid pressure in the pump will decrease, posing a great safety hazard to the driver and endangering the lives of the people in the car.

[0005] Therefore, a novel automobile brake hose is proposed to address the above problems. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a novel automobile brake hose, which has the advantages of strong structure, not easy to fall off, and improved automobile safety.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides a novel automobile brake hose, comprising a rubber tube 1, one end of the rubber tube 1 is fixedly provided with a bearing 2, the interior of the bearing 2 is slidably connected with a metal shell 3, the inner side of the metal shell 3 is fixedly connected with a threaded interface 4, the outer side of the metal shell 3 is fixedly provided with a telescopic shaft 21, the top of the telescopic shaft 21 is fixedly connected with a limiting buckle 7, the bottom end of the limiting buckle 7 is fixedly provided with a spring 20, the outer side of the threaded interface 4 is spirally connected with a threaded interface 25, one side of the threaded interface 25 is fixedly provided with a groove 8, the interior of the threaded interface 25 is fixedly connected with a rubber tube 26, the end of the rubber tube 26 is fixedly connected with a fixing ring 9, the interior of the fixing ring 9 is fixedly connected with a bearing 210, the spiral connection is a movable connection, and the connection of the limiting buckle 7 is a fixed connection. This structure greatly enhances the stability of the hose and makes it difficult to fall off.

[0024] Specifically, the outer side of the rubber tube 1 is slidably connected to a fixing block 17, the top of the fixing block 17 is fixedly connected to a fixing block 2 18, and the fixing block 2 18 is set in an L shape. The fixing block 17 can fix the hose to the bottom of the vehicle body or other positions, so that the hose fits firmly on the vehicle body without shaking.

[0025] Furthermore, a screw 19 is spirally connected to the top of the fixing block 18, and the screw 19 passes through the fixing block 18. A rubber sleeve 22 is slidably connected to the outer side of the rubber tube 1. When the brake hose ages and leaks, the pressure in the tube will not drop rapidly, thereby increasing the stability of the hose.

[0026] Furthermore, a rubber interface 13 is fixedly provided at the other end of the rubber tube 1, and a rubber head 14 is fixedly provided inside the rubber interface 13. The rubber material increases the friction between the interface and the hydraulic master pump interface, making it difficult to fall off.

[0027] It is worth noting that a fixing rod 15 is fixedly connected inside the rubber head 14, and a hydraulic sensor 16 is fixedly connected to one side of the fixing rod 15. When the pressure inside the hose is insufficient, the hydraulic sensor 16 will alarm the passengers in the car, so that the passengers can get off the car in time and ask for rescue.

[0028] It is worth noting that the bearing 2 10 is internally slidably connected with a heat-resistant tube 11, and the end of the heat-resistant tube 11 is fixedly connected with a threaded interface 3 12. When the car brakes, the tire will drive the hose to swing left and right and transfer heat to the hose. The heat-resistant tube 11 can withstand the heat caused by the tire braking very well.

[0029] Among them, the hydraulic sensor 16, the heat-resistant pipe 11, and the screw 19 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller, etc., which are not the main technical points of this patent and will not be described in detail.

[0030] Working principle and process: When using the automobile brake hose, the user can spirally connect one end of the rubber tube 1 to the threaded interface 25, rotate the metal shell 3 fixed in the bearing 2, and the metal shell 3 drives the threaded interface 4 to rotate. After the spiral connection, the limit buckle 7 is clamped into the groove 8. The threaded interface 25 and the rubber tube 26 are fixed to increase the stability of the brake hose. The fixing ring 9 fixes the rubber tube 26 and the bearing 210. The limit buckle 7 is dragged to pull the telescopic shaft 21. The rotating threaded interface 14 is fixed to the threaded interface 25. The elastic force of the spring 20 will pull the limit buckle 7. The limit buckle 7 is buckled in the groove 8, which enhances the safety of the brake device. The bearing 210 allows the heat-resistant tube 11 to rotate. Since the threaded interface three 12 is fixed on the brake master cylinder, the heat-resistant tube 11 will be driven to rotate when the car turns left or right, but the brake hose will not be driven to rotate, so that the hose is not easy to rotate and fall off. The brake hose is covered with a fixing block 17, and the hose is fixed to the car body with a screw 19 penetrating the fixing block two 18 to strengthen the stability of the device. The rubber interface 13 and the rubber head 14 will increase the friction between the brake hose and the brake master cylinder, increase the sealing, and not easily leak. The hydraulic sensor 16 inside the rubber head 14 is fixed by the fixing rod 15. The hydraulic sensor 16 will alarm the driver when the hydraulic pressure is lower than the standard value, so that the people in the car can take corresponding measures in time to ensure life safety.
