Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to a labyrinth-type brake hose bracket and a brake hose assembly. Background Art

[0002] Currently, there are two general types of brake hose assembly structures used in automotive brake lines: a bolt-and-nut fastening connection and a direct-insert bracket-type interference fit. The first structure is relatively costly; the second is limited by the interference fit. If the design is too large, the insertion force is too high, making assembly difficult; if the design is too small, it is prone to post-sale disengagement. Therefore, to address the cost contradiction and the risk of disengagement, a practical and innovative anti-disengagement bracket is needed. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a labyrinth-type brake hose bracket and a brake hose assembly. The labyrinth-type brake hose bracket provided by the present invention can effectively prevent the brake hose from slipping off the bracket.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] The first aspect of the present utility model provides a labyrinth-type brake hose bracket, comprising a hose connecting plate and a frame connecting plate fixedly connected to the hose connecting plate, wherein the hose connecting plate is perpendicular to the frame connecting plate, and a hose connecting channel and a bayonet are provided on the hose connecting plate, wherein the opening of the hose connecting channel is arranged at the edge of the hose connecting plate, and the other end of the hose connecting channel is connected to the bayonet; the size of the hose connecting channel gradually increases from the opening to the bayonet; and a fixing hole is provided on the frame connecting plate.

[0006] In some embodiments of the present invention, the hose connecting plate and the frame connecting plate are fixedly connected via curved reinforcing ribs.

[0007] In some embodiments of the present invention, the hose connection channel is an S-shaped channel.

[0008] In some embodiments of the present invention, the hose connecting channel is an inverted L-shaped channel.

[0009] In some embodiments of the present invention, a protection fence is provided on the edge of the hose connecting plate, and the protection fence is perpendicular to the hose connecting plate.

[0010] In some embodiments of the present invention, the frame connecting plate is smoothly connected to the protection rail.

[0011] In some embodiments of the present invention, the frame connecting plate is fixed to the shock absorber of the vehicle body by bolting or welding, and the labyrinth brake hose bracket is perpendicular to the shock absorber housing.

[0012] A second aspect of the present invention provides a brake hose assembly, comprising the above-mentioned labyrinth brake hose bracket, a brake hose, and a connecting sleeve for connecting two sections of brake hose, wherein the connecting sleeve is fixed in a bayonet of the labyrinth brake hose bracket.

[0013] In some embodiments of the present invention, the connecting sleeve is a rubber stopper.

[0014] In some embodiments of the present invention, the size of the bayonet is larger than that of the brake hose, and the bayonet is transitionally matched with the connecting sleeve.

[0015] The beneficial effects of the utility model are:

[0016] The utility model discloses a labyrinth-type brake hose bracket, which saves costs and reduces the risk of brake hose detachment without compromising component performance. Specifically, the labyrinth-type brake hose bracket is designed with a hose connection channel and a bayonet, with the hose connection channel gradually increasing in size from the opening to the bayonet. The opening of the hose connection channel forms a slight interference fit with the rubber sleeve, gradually transitioning to a transition fit. When assembled to the labyrinth-type brake hose bracket, the rubber sleeve of the brake hose is pushed into the bayonet through the hose connection channel, eliminating the need for other fasteners. Furthermore, during vehicle movement, the curved design of the hose connection channel prevents the rubber sleeve from slipping out of the bracket, thus minimizing the risk of after-sales detachment. After the rubber sleeve is inserted into the bayonet, the brake hose rotates in the direction of vehicle movement due to lateral forces. The hose moves only within the bayonet and hose connection channel of the brake hose bracket, where friction generated by the bracket's edges prevents it from slipping out. Therefore, the labyrinth-type brake hose bracket of the utility model has a high reliability, a sophisticated design, and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art to more clearly understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to specific embodiments.

[0022] See also Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the two-dimensional structure of the new maze-type bracket provided in the embodiment of the utility model. Figure 2 This is a structural schematic diagram of a brake hose assembly provided in an embodiment of the present utility model.

[0023] This embodiment provides a labyrinth-type brake hose bracket, which primarily comprises a hose connection plate 2 and a frame connection plate 1 fixedly connected to the hose connection plate 2. The hose connection plate 2 is used to secure the brake hose 7, or effectively secure the brake hose 7 by securing the connection sleeve on the brake hose 7, preventing the brake hose 7 from slipping off the labyrinth-type brake hose bracket. The frame connection plate 1 is used to secure the labyrinth-type brake hose bracket to the vehicle frame, either by bolting or welding.

[0024] In some embodiments, the present invention does not limit the shape of the hose connection plate 2; it can be a square, circular, or irregularly shaped plate. To improve the brake hose's securement and prevent it from slipping off the bracket, the hose connection plate 2 is typically made of a material with high hardness, strength, and low deformation, such as mild steel, high-strength steel, advanced high-strength steel, aluminum-magnesium alloy, or carbon fiber reinforced plastic (CFRP). The thickness of the hose connection plate 2 can be adjusted based on actual needs.

[0025] In some embodiments, the present invention does not limit the shape of the frame connecting plate 1; it can be a square, circular, or irregularly shaped plate, as long as it can be secured to the vehicle frame. To improve the bracket's securement and prevent it from falling off the vehicle frame, the frame connecting plate 1 is generally made of a material with high hardness, strength, and low deformation, such as low-carbon steel, high-strength steel, advanced high-strength steel, aluminum-magnesium alloy, or carbon fiber reinforced plastic (CFRP). The thickness of the frame connecting plate 1 can be adjusted based on actual conditions.

[0026] In some embodiments, the frame connecting plate 1 and the hose connecting plate 2 of the present invention can be connected at any angle. For example, the angle between the two plates can be 60°, 90°, 120°, 150°, etc., and the specific angle can be selected based on the frame structure. Preferably, the hose connecting plate 2 is perpendicular to the frame connecting plate 1, i.e., the angle between the two plates is 90°. When connected vertically, the hose connecting plate 2 is perpendicular to the frame, and when the brake hose is clamped and secured in the hose connecting plate 2, it is parallel to the frame, without affecting the performance of the frame, brake hose, and other components.

[0027] The hose connecting plate 2 is provided with a hose connecting channel 5 and a bayonet 6 . The opening of the hose connecting channel 5 is arranged at the edge of the hose connecting plate 2 , and the other end of the hose connecting channel 5 is connected to the bayonet 6 .

[0028] In some embodiments, Figure 1 and Figure 2 For reference, the hose connection plate 2 is provided with a hose connection channel 5 and a bayonet 6. Both the hose connection channel 5 and the bayonet 6 are created by cutting out corresponding portions of the hose connection plate 2. The opening of the hose connection channel 5 (i.e., channel opening 501) is located at the edge of the hose connection plate 2 near the frame connection plate 1, and the other end of the hose connection channel 5 connects to the bayonet 6.

[0029] Of course, in practice, the shape of the bayonet 6 is not limited; its cross-section can be circular, square, or otherwise. Due to the shape of the brake hose 7 or the connecting sleeve, a circular shape is preferred. This prevents punctures on the brake hose 7 or the connecting sleeve and balances the axial forces acting on the brake hose 7 or the connecting sleeve, thereby improving the securing effect. The bayonet 6 is larger than the brake hose 7 to ensure easy installation within the bayonet 6.

[0030] In some embodiments, the brake hose 7 or connecting sleeve can be pushed forward through the hose connection channel into the bayonet 6. The brake hose 7 or connecting sleeve can pass through the channel opening 501 at any angle. To improve the securing effect, it is best to pass through the channel opening 501 vertically, and after being pushed into the bayonet 6, the brake hose 7 or connecting sleeve is perpendicular to the hose connection plate 2.

[0031] The size of the hose connection channel 5 gradually increases from the channel opening 501 to the bayonet 6 .

[0032] In some embodiments, channel opening 501 has a narrow opening range, providing a slight interference fit with the brake hose 7 or connecting sleeve. Transition channel 502 gradually increases in opening range from channel opening 501 to bayonet 6, providing a transition fit with the brake hose 7 or connecting sleeve. This slight interference fit and transition fit design allows the brake hose 7 or connecting sleeve to be easily pushed into bayonet 6 through hose connection channel 5 during assembly, eliminating the need for additional tightening. This effectively prevents the brake hose 7 or connecting sleeve from slipping out of the bracket during vehicle movement, minimizing the risk of post-sale disengagement.

[0033] The frame connecting plate 1 is provided with fixing holes 3 .

[0034] In some embodiments, the shape of fixing hole 3 is not limited and can be circular, square, or hexagonal. The provision of fixing hole 3 allows the labyrinth-shaped brake hose bracket to be secured to the corresponding position of the vehicle frame using bolts or hinges. Due to the shape of the bolts, the fixing hole is preferably circular. This avoids the problem of bolts being unable to secure the labyrinth-shaped brake hose bracket. The size of fixing hole 3 can be set according to actual conditions.

[0035] In some embodiments, the frame connecting plate 1 and the hose connecting plate 2 can be integrally formed or assembled. When the frame connecting plate 1 and the hose connecting plate 2 are assembled, the hose connecting plate 2 and the frame connecting plate 1 can be fixedly connected by a curved reinforcing rib.

[0036] In some embodiments, the shape of the hose connection channel 5 is not limited and may be an arc-shaped channel, an S-shaped channel, an L-shaped channel, an inverted L-shaped channel, or a snail-shaped channel. The inner edge of the hose connection channel 5 is smooth, free of burrs and sharp corners, ensuring that the brake hose 7 or the connecting sleeve can be smoothly passed through the hose connection channel 5 and pushed into the bayonet 6.

[0037] A protective fence 4 is provided on the edge of the hose connecting plate 2 . The protective fence 4 is a flange of the bracket, which increases the strength of the bracket in terms of technology.

[0038] In some embodiments, the guardrail 4 is a plate that can be connected to the hose connection plate 2 at any angle, such as 90°, 120°, 150°, etc. Preferably, the guardrail 4 and the hose connection plate 2 are connected perpendicularly, i.e., the angle between the guardrail 4 and the hose connection plate 2 is 90°.

[0039] In some embodiments, the guardrail 4 and hose connection plate 2 can be integrally formed or assembled. When assembled, the guardrail 4 and hose connection plate 2 can be securely connected by curved reinforcing ribs. These ribs enhance the strength of the bracket, thereby increasing its service life.

[0040] Of course, it is understood that the guardrail 4 and the frame connecting plate 1 are on the same side of the hose connecting plate 2. In order to improve the protection effect and avoid the brake hose 7 or the connecting sleeve from sliding on the hose connecting plate of the labyrinth brake hose bracket, the frame connecting plate 1 can be smoothly connected to the guardrail 4.

[0041] In some embodiments, the guardrail 4 is a semi-enclosed guardrail, and the hose connecting plate 2 is not provided with guardrails 4 at all edges. Figure 1 , protective rails 4 are provided on both edges of the hose connection plate 2. The hose connection plate 2 is roughly an irregular square with four sides. One edge of the hose connection plate 2 is connected to the frame connection plate 1. A protective rail 4 is provided on the edge opposite the frame connection plate 1. A protective rail 4 is also provided on the edge connected to the frame connection plate 1. The remaining edge is not provided with a protective rail 4, but instead has a passage opening 501 near the frame connection plate 1.

[0042] In some embodiments, the guardrail 4 may also be a fully enclosed guardrail, and guardrails 4 are provided on all edges of the hose connecting plate 2 except for the positions of the frame connecting plate 1 and the channel opening.

[0043] In some embodiments, the frame connecting plate 1 is fixed to the shock absorber of the vehicle body by bolting or welding, and the labyrinth brake hose bracket is perpendicular to the shock absorber housing.

[0044] Of course, it is understandable that the labyrinth brake hose bracket can be directly welded to the shock absorber of the vehicle body through the frame connecting plate 1 to fix the brake hose 7. The labyrinth brake hose bracket is vertically welded to the shock absorber housing.

[0045] In some embodiments, the connecting sleeve is a rubber sleeve 8 .

[0046] The utility model also provides a brake hose assembly, which can be referred to Figure 2 , including the above-mentioned labyrinth brake hose bracket, a brake hose 7 and a connecting sleeve for connecting two sections of brake hose, wherein the connecting sleeve is fixed in the bayonet 6 of the labyrinth brake hose bracket.

[0047] The connecting sleeve is a rubber sleeve 8.

[0048] In some embodiments, the rubber sleeve 8 on the brake hose 7 is perpendicular to the hose connecting plate 2 and fixed in the bayonet 6. The rubber sleeve 8 is pushed into the hose connecting channel 5 from the channel opening 501, along the transition channel 502 of the hose connecting channel 5, and into the bayonet 6 to be fixed.

[0049] In some embodiments, the size of the bayonet 6 is larger than that of the brake hose 7 , and the bayonet 6 and the connecting sleeve (ie, the rubber sleeve 8 ) are transitionally matched.

[0050] Of course, it is understandable that the rubber sleeve 8 on the brake hose 7 and the labyrinth-shaped brake hose bracket are both designed with two-section dimensions. The first section is an interference fit, and the second section is a transition fit, that is, the channel opening 501 and the rubber sleeve 8 are an interference fit, and the bayonet 6 and the rubber sleeve 8 are a transition fit. The bracket is designed to be a nearly "S"-shaped labyrinth, so that the rubber sleeve 8 can be pushed to the bottom in an S-shaped manner during assembly, without the need for other tightening operations. During the movement of the entire vehicle, the brake hose rubber sleeve can prevent the brake hose from slipping out and falling off due to the S-shaped bending design, thereby avoiding the risk of falling off after sales.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
