Description

Technical Field

[0001] The utility model relates to the field of brake hard pipes, in particular to a brake hard pipe assembly joint. Background Art

[0002] The brake hose assembly is a pipe component made of rigid material (such as steel) that distributes and transmits brake fluid pressure in a vehicle's braking system. By connecting the hydraulic system between the master cylinder and the brakes, the brake hose assembly transmits the required brake pressure to the wheel brake components, thereby achieving the vehicle's braking function.

[0003] The prior art (application number CN202021994951.2, application date 2020.09.11) discloses a brake hard pipe connector, a brake hard pipe device assembly and a vehicle. The specification records that the joint on the fixed bracket is connected to the brake hard pipe by torque. Since the vehicle will inevitably vibrate during driving, the sealing effect relying on torque connection is poor and there is even a risk of leakage. Therefore, it is necessary to make improvements to the connection structure of the joint and the brake hard pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a brake tube assembly joint to solve the problem that the existing brake tube assembly joint has poor sealing effect and even has the risk of leakage. The specific technical solution is as follows:

[0005] The brake hard tube assembly joint includes a brake hard tube, a connecting head and a fixed bracket. The fixed bracket is curved and provided with a connecting platform. The connecting head is passed through the connecting platform. A raised outer ring and an inner ring are provided on the end face of the brake hard tube. An annular groove is formed between the outer ring and the inner ring to accommodate the connecting head. The inner wall of the outer ring is threadedly engaged with the connecting head. A silicone layer is filled between the inner wall of the inner ring and the connecting head. The inner ring is tilted toward the direction of the outer ring.

[0006] Preferably, the inclination angle of the inner ring is less than 15°.

[0007] Preferably, the bottom of the silicone layer is provided with a protrusion extending along the bottom surface of the annular groove, a first groove is provided on the end face of the connecting head, and a second groove is provided on the bottom surface of the annular groove, and the first groove and the second groove form an accommodating space for accommodating the protrusion.

[0008] Preferably, the top surface or the bottom surface of the protrusion protrudes outward.

[0009] Preferably, an inclined surface is provided at the outer corner of the silicone layer.

[0010] Preferably, a plurality of notches distributed in a ring shape are provided on the top surface of the inner ring.

[0011] Preferably, opposite sides of the fixing bracket form a concave surface and a convex surface respectively, and the convex surface is provided with a plurality of reinforcing rods arranged in a transverse direction.

[0012] The beneficial effects of the utility model are as follows: since the outer ring and the connector are detachably matched, the brake tube can be flexibly replaced. The brake tube can be detached from the connector by twisting the brake tube relative to the outer ring. By arranging a silicone layer between the inner ring and the connector, the overall sealing effect can be enhanced and the airtightness can be improved. The silicone has good elasticity and buffering properties. Arranging it between the inner ring and the connector can effectively absorb vibration energy and reduce vibration transmission, thereby protecting mechanical parts from damage.

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The existing connector 3 on the fixing bracket 2 and the brake tube 1 are connected by torque, which results in poor sealing. Figure 1-4 The present invention provides an embodiment to solve the above-mentioned problem, specifically comprising a brake hard pipe 1, a connector 3 and a fixing bracket 2. The fixing bracket 2 is curved. As can be understood, the existing new energy vehicle battery pack is usually arranged under the vehicle floor and occupies a very large space. This will make it difficult to arrange the connector of the brake hard pipe 1, and the space available for arrangement is limited. In order to adapt to the uneven cabin wall, the fixing bracket 2 needs to be designed to be curved.

[0023] Furthermore, the fixing bracket 2 is provided with a connecting platform, and the connecting head 3 is passed through the connecting platform. A raised outer ring 11 and an inner ring 12 are provided on the end surface of the brake tube 1. An annular groove 13 is formed between the outer ring 11 and the inner ring 12 to accommodate the connecting head 3. The inner wall of the outer ring 11 is threadedly engaged with the connecting head 3, and a silicone layer 4 is filled between the inner wall of the inner ring 12 and the connecting head 3. Since the outer ring 11 and the connecting head 3 are threadedly engaged, the brake tube 1 can be flexibly replaced. By twisting the brake tube 1 relative to the outer ring 11, the brake tube 1 can be detached from the connecting head 3. By arranging the silicone layer 4 between the inner ring 12 and the connecting head 3, the overall sealing effect can be enhanced and the airtightness can be improved. On the basis of the detachable engagement between the outer ring 11 and the connecting head 3, the silicone layer 4 is also easily replaced. Furthermore, silicone has good elasticity and buffering properties. Arranging it between the inner ring 12 and the connecting head 3 can effectively absorb vibration energy, reduce vibration transmission, and thus protect mechanical parts from damage.

[0024] In some embodiments, the inner ring 12 is tilted toward the outer ring 11. It is understood that by tilting the inner ring 12, when the brake tube 1 is installed on the connector 3, the inner ring 12 can cooperate with the connector 3 to squeeze the silicone layer 4, thereby achieving an enhanced sealing effect. Preferably, the tilt angle of the inner ring 12 is less than 15°. The tilt angle of the inner ring 12 is controlled to a certain degree to provide sufficient space for installing the silicone layer 4.

[0025] Preferably, the bottom of the silicone layer 4 is provided with a raised portion extending along the bottom surface of the annular groove 13, a first groove 31 is provided on the end face of the connecting head 3, and a second groove 14 is provided on the bottom surface of the annular groove 13. The first groove 31 and the second groove 14 form an accommodating space for accommodating the raised portion. By setting the raised portion to cooperate with the first groove 31 or the second groove 14, a positioning effect can be achieved during installation. Preferably, the top surface or bottom surface of the end of the raised portion protrudes outward.

[0026] In order to facilitate the guidance of the liquid flowing in the connector 3 and the brake tube 1, in some embodiments, an inclined surface 41 is provided at the outer corner of the silicone layer 4. Specifically, the inclined surface 41 is formed on the outer side of the top surface of the silicone layer 4. When the liquid flows onto the silicone layer 4, the inclined surface 41 can guide the flow of the liquid.

[0027] Preferably, a plurality of notches 15 distributed in a ring shape are provided on the top surface of the inner ring 12, and partitions are formed between adjacent notches 15. These partitions are usually thin, so the diameter of the inner ring 12 can be adjusted by bending the partitions.

[0028] In order to improve the applicability of the fixing bracket 2, a concave surface and a convex surface are formed on opposite sides of the fixing bracket 2 respectively. By forming the above-mentioned concave surface and convex surface, it is ensured that the fixing bracket 2 can be installed on the uneven cabin wall. Preferably, a plurality of transversely arranged reinforcing rods 21 are provided on the convex surface. By providing the reinforcing rods 21, the strength of the fixing bracket 2 can be improved.

[0029] It should be noted that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature designated as "first" or "second" may explicitly or implicitly include one or more of the aforementioned features.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
