Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a lightweight brake pipe assembly. Background Technology

[0002] Automotive brake hoses (commonly known as brake lines) are components used in automotive braking systems. Their main function is to transmit braking fluid during braking, ensuring that braking force is transmitted to the brake shoes or calipers to generate braking force, thus making braking effective at all times. They are an indispensable component in the braking process of a car. A hydraulic brake hose assembly consists of a brake hose and a brake hose connector. The brake hose and the brake hose connector are permanently connected. This connection is achieved by the corrugation or cold extrusion deformation of the connector relative to the hose. With the development of the times, the automotive industry is also developing faster and faster, so the demand for brake hose assemblies has also increased significantly.

[0003] In the brake hose assembly, because the brake hose itself is relatively soft, when installing the brake hose on the vehicle frame, multiple metal mounting brackets are needed to install the brake hoses at their designated positions on the vehicle frame in sequence. The two ends of the brake hose are connected to the brake pump and brake disc respectively through hose connectors. Since the metal mounting brackets themselves have a certain weight, this will inevitably lead to an excessive weight of the vehicle body, affecting the subsequent range of the vehicle. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight brake hose assembly to solve the problem that conventional brake hoses are mounted on the vehicle frame using multiple metal mounting brackets, resulting in excessive overall vehicle weight.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0009] The first end of the connector is fixedly connected to the first connector, and the second end of the connector is fixedly connected to the second connector. The connector is detachably mounted on the vehicle frame.

[0010] Furthermore, the first adapter includes a first adapter sleeve and a mounting base. The first adapter sleeve is fixedly sleeved on the second end of the first hose and protrudes beyond the second end of the first hose. The mounting base has a first clearance hole that is adapted to the first adapter sleeve. The mounting base is sleeved on the part of the first adapter sleeve that protrudes beyond the second end of the first hose through the first clearance hole. The mounting base is detachably mounted on the pump body of the brake pump.

[0011] Furthermore, the second adapter includes a second adapter sleeve, a bent adapter tube, and a mounting block. The second adapter sleeve is fixedly sleeved on the second end of the second flexible hose and protrudes beyond the second end of the second flexible hose. The first end of the bent adapter tube is connected to and communicates with the second adapter sleeve. The second end of the bent adapter tube is connected to the mounting block. A second clearance hole is provided in the middle of the mounting block. The mounting block is sleeved on the brake disc at a preset position through the second clearance hole.

[0012] Furthermore, the mounting base is provided with at least one first mounting part, which corresponds to a first mounting position on the pump body. The first mounting part is a first through hole, and a first mounting hole is provided at the first mounting position. The shank of the bolt passes through the first through hole and is tightened into the first mounting hole, so that the head of the bolt presses against the mounting base, thereby installing the mounting base at the first mounting position on the pump body through the first mounting part.

[0013] Furthermore, the mounting base has an overall "L" shaped structure, the mounting base has an "L" shaped bend, and a first reinforcing part is provided on the mounting base at the bend.

[0014] Furthermore, the mounting base is provided with a fixing clip, and the fixing clip has a locking groove in the middle. The locking groove is made of elastic material and the width of the locking groove is not greater than the outer diameter of the first adapter sleeve. The fixing clip is sleeved on the part of the first adapter sleeve that protrudes from the second end of the first hose, so as to lock and fix the mounting base on the part of the first adapter sleeve that protrudes from the second end of the first hose.

[0015] Furthermore, the first end of the connector is riveted and fixed to the first connector head, and the second end of the connector is riveted and fixed to the second connector head;

[0016] The first connector has a protruding first rivet head on the side near the rigid tube. The first end of the connector has a first rivet hole. The first rivet head is adapted to the first rivet hole. The first rivet head passes through the first rivet hole and is riveted to the first rivet hole by pressing.

[0017] The second connector has a second rivet head protruding from the side near the rigid tube. The second end of the connector has a second rivet hole. The second rivet head is adapted to the second rivet hole. The second rivet head passes through the second rivet hole and is riveted to the second rivet hole by pressing.

[0018] Furthermore, both the first connector and the second connector are made of metal.

[0019] Furthermore, the connecting seat is provided with a second mounting part and a third mounting part. The second mounting part is provided at a second mounting position of the vehicle frame, and the third mounting part is provided at a third mounting position of the vehicle frame. The second mounting part is a second through hole, and a second mounting hole is provided at the second mounting position. The shank of the bolt passes through the second through hole and is tightened into the second mounting hole, so that the head of the bolt presses against the connecting seat. Thus, the connecting seat is installed at the second mounting position of the vehicle frame through the second mounting part. The third mounting part is a third through hole, and a third mounting hole is provided at the third mounting position. The shank of the bolt passes through the third through hole and is tightened into the third mounting hole, so that the head of the bolt presses against the connecting seat. Thus, the connecting seat is installed at the third mounting position of the vehicle frame through the third mounting part.

[0020] Furthermore, the two ends of the rigid tube are bent according to a preset shape to fix the installation paths of the first flexible tube and the second flexible tube at preset positions.

[0021] Compared with existing technologies, the advantages of the lightweight brake pipe assembly are as follows:

[0022] 1) By installing the first hose and the second hose at both ends of the rigid pipe respectively, the second end of the first hose is connected to the brake pump through the first adapter, and the second end of the second hose is connected to the brake disc through the second adapter. The first end of the connector is fixed to the first connector head, and the second end of the connector is fixed to the second connector head. It is not necessary to install connectors at each position of the hose, which greatly reduces the overall weight of the brake pipe assembly.

[0023] 2) The first adapter is fixed to the first hose through the first adapter sleeve. The mounting base is sleeved on the adapter sleeve by the first clearance hole and can be detachably installed on the pump body of the brake pump. On the one hand, it realizes a stable connection between the first hose and the brake pump, which facilitates installation and subsequent maintenance. On the other hand, it improves the sealing and connection reliability, avoids brake fluid leakage, and improves the compatibility with the brake pump connection.

[0024] 3) The second adapter is fixed to the second hose through the second adapter sleeve. The bent adapter tube connects the adapter sleeve and the mounting block. The mounting block is fitted into the preset position of the brake disc through the second clearance hole. While ensuring the smooth transmission of brake fluid, the layout is reasonable and further enhances the stability of the connection between the second adapter and the brake disc, ensuring the effective transmission of brake pressure.

The connector 60 is detachably mounted on the vehicle frame.

[0032] Specifically, both the first connector 21 and the second connector 31 are sleeves.

[0033] As can be seen, by installing the first hose 20 and the second hose 30 at the two ends of the rigid pipe 10 respectively, the second end of the first hose 20 is connected to the brake pump through the first adapter 40, the second end of the second hose 30 is connected to the brake disc through the second adapter 50, the first end of the connecting seat 60 is fixed on the first connector 21, and the second end of the connecting seat 60 is fixed on the second connector 31, it is not necessary to set the connecting seat 60 at each position of the hose, which greatly reduces the overall weight of the brake pipe assembly.

[0034] In one embodiment, the first adapter 40 includes a first adapter sleeve 41 and a mounting base 42. The first adapter sleeve 41 is fixedly sleeved on the second end of the first hose 20 and protrudes from the second end of the first hose 20. The mounting base 42 has a first clearance hole 43, which is adapted to the first adapter sleeve 41. The mounting base 42 is sleeved on the part of the first adapter sleeve 41 that protrudes from the second end of the first hose 20 through the first clearance hole 43. The mounting base 42 is detachably mounted on the pump body of the brake pump.

[0035] As can be seen, the first adapter 40 is fixed to the first hose 20 through the first adapter sleeve 41, and the mounting base 42 is sleeved on the adapter sleeve by the first clearance hole 43 and can be detachably installed on the pump body of the brake pump. On the one hand, it realizes a stable connection between the first hose 20 and the brake pump, which facilitates installation and subsequent maintenance. On the other hand, it improves the sealing performance and connection reliability, avoids brake fluid leakage, and enhances the compatibility with the brake pump connection.

[0036] In one embodiment, the second adapter 50 includes a second adapter sleeve 51, a bent adapter tube 52, and a mounting block 53. The second adapter sleeve 51 is fixedly sleeved on the second end of the second hose 30 and protrudes from the second end of the second hose 30.

A second clearance hole 54 is provided in the middle of the mounting block 53. The mounting block 53 is sleeved on the brake disc at a preset position through the second clearance hole 54.

[0037] As can be seen, the second adapter 50 is fixed to the second hose 30 through the second adapter sleeve 51, and the bent adapter tube 52 connects the adapter sleeve and the mounting block 53. The mounting block 53 is sleeved on the preset position of the brake disc through the second clearance hole 54. While ensuring the smooth transmission of brake fluid, the layout is reasonable, and at the same time, it further enhances the stability of the connection between the second adapter 50 and the brake disc, ensuring the effective transmission of brake pressure.

[0038] In one embodiment, the mounting base 42 is provided with at least one first mounting part, which is provided corresponding to the first mounting position on the pump body. The first mounting part is a first through hole 44, and a first mounting hole is provided at the first mounting position. The shank of the bolt passes through the first through hole 44 and is tightened into the first mounting hole, so that the head of the bolt presses against the mounting base 42, thereby installing the mounting base 42 at the first mounting position on the pump body through the first mounting part.

[0039] Specifically, the first mounting hole is a threaded hole.

[0040] Specifically, there are two first mounting parts, and two corresponding first mounting holes. The number of first mounting parts is set according to the specific situation, which will not be elaborated here.

[0041] As can be seen, the mounting base 42 is fixed with the first mounting hole of the brake pump body through the first through hole 44 and the first mounting hole of the brake pump body with bolts, so that the bolt head presses against the mounting base 42, realizing a firm connection between the mounting base 42 and the pump body. This not only ensures reliable installation but also facilitates disassembly and maintenance. It can effectively prevent the mounting base 42 from loosening, ensure the stability of the connection between the first adapter 40 and the brake pump, and avoid affecting the transmission of brake fluid due to loose connection.

[0042] In one embodiment, the mounting base 42 has an overall "L" shaped structure, and the mounting base 42 has an "L" shaped bend. A first reinforcing part 45 is provided on the mounting base 42 at the bend.

[0043] Specifically, the first reinforcing part 45 is a reinforcing rib.

[0044] Specifically, mounting base 42 is an "L"-shaped mounting plate.

[0045] As can be seen, by setting the mounting base 42 as an "L" shaped structure and setting the first reinforcing part 45 at the bending part, the first reinforcing part 45 enhances the structural strength of the bending part of the mounting base 42, avoids deformation of the mounting base 42 due to force or vibration during long-term use, ensures the stability and service life of the mounting base 42, and indirectly ensures the connection reliability of the first adapter 40.

[0046] In one embodiment, the mounting base 42 is provided with a fixing clip 46, and a clip groove 460 is formed in the middle of the fixing clip 46. The clip groove 460 is made of elastic material and the width of the clip groove 460 is not greater than the outer diameter of the first adapter sleeve 41. The fixing clip 46 is sleeved on the part of the first adapter sleeve 41 that protrudes from the second end of the first hose 20, so as to fix the mounting base 42 in a clip at the part of the first adapter sleeve 41 that protrudes from the second end of the first hose 20.

[0047] As can be seen, by setting the elastic snap-fit, the mounting base 42 is snap-fitted and fixed on the adapter sleeve, which further enhances the tightness of the connection between the mounting base 42 and the first adapter sleeve 41, prevents the mounting base 42 from shaking relative to the adapter sleeve, ensures that the two are synchronous and stable, and improves the overall structural stability of the first adapter 40.

[0048] In one embodiment, the first end of the connector 60 is riveted and fixed to the first connector 21, and the second end of the connector 60 is riveted and fixed to the second connector 31. The first connector 21 has a first rivet head 22 protruding from the side near the rigid tube 10. The first end of the connector 60 has a first rivet hole 61, and the first rivet head 22 is adapted to the first rivet hole 61. The first rivet head 22 passes through the first rivet hole 61 and is riveted to the first rivet hole 61 by pressing. The second connector 31 has a second rivet head 32 protruding from the side near the rigid tube 10. The second end of the connector 60 has a second rivet hole 62, and the second rivet head 32 is adapted to the second rivet hole 62. The second rivet head 32 passes through the second rivet hole 62 and is riveted to the second rivet hole 62 by pressing.

[0049] As can be seen, by setting a first rivet head 22 on the first connector 21, setting a second rivet head 32 on the second connector 31, and opening a first rivet hole 61 and a second rivet hole 62 on the connector seat 60, the first rivet head 22 and the second rivet head 32 are riveted and fixed on the connector seat 60 by pressing, a tight connection between the connector seat 60 and the first connector 21 and the second connector 31 is achieved, effectively avoiding connection failure due to loosening during use, and ensuring a stable connection between the brake pipes.

[0050] In one embodiment, both the first connector 21 and the second connector 31 are made of metal.

[0051] Specifically, both the first connector 21 and the second connector 31 are made of aluminum alloy.

[0052] It is evident that both the first connector 21 and the second connector 31 are made of metal, which greatly improves the wear resistance of the connection ends of the first hose 20 and the second hose 30, and significantly extends the service life of the connectors.

[0053] In one embodiment, the connecting seat 60 is provided with a second mounting part and a third mounting part. The second mounting part is set at a second mounting position of the frame, and the third mounting part is set at a third mounting position of the frame. The second mounting part is a second through hole 63, and a second mounting hole is opened at the second mounting position. The shank of the bolt passes through the second through hole 63 and is tightened into the second mounting hole, so that the head of the bolt presses against the connecting seat 60. The connecting seat 60 is then installed at the second mounting position of the frame through the second mounting part. The third mounting part is a third through hole 64, and a third mounting hole is opened at the third mounting position. The shank of the bolt passes through the third through hole 64 and is tightened into the third mounting hole, so that the head of the bolt presses against the connecting seat 60. The connecting seat 60 is then installed at the third mounting position of the frame through the third mounting part.

[0054] Specifically, both the second and third mounting holes are threaded holes.

[0055] As can be seen, by setting the second through hole 63 and the third through hole 64 on the connecting seat 60 corresponding to the frame mounting position, and by using bolts to pass through the through holes and tighten them with the frame mounting holes, the bolt heads press against the connecting seat 60, thus achieving a stable installation of the connecting seat 60 and the frame. This not only ensures the reliability of the connecting seat 60's installation on the frame, but also enhances the stability of the overall installation structure through two-point positioning.

[0056] In one implementation, the two ends of the rigid tube 10 are bent according to a preset shape to fix the installation paths of the first flexible tube 20 and the second flexible tube 30 according to a preset position.

[0057] Specifically, the rigid pipe 10 includes a first horizontal pipe 11, a second horizontal pipe 12, a first bent pipe 13, a second bent pipe 14, and a vertical pipe 15, wherein the first horizontal pipe 11 extends along a first direction ( Figure 1 In the X direction), the first end of the first horizontal pipe 11 is connected to and communicates with the first bent pipe 13, the first end of the vertical pipe 15 is vertically arranged and its first end is connected to the second end of the first bent pipe 13, the second end of the vertical pipe 15 is connected to and communicates with the first flexible pipe 20, the second end of the first horizontal pipe 11 is connected to and communicates with the first end of the second bent pipe 14, and the second horizontal pipe 12 is along the second direction ( Figure 1 Extending in the Y direction, the first end of the second horizontal tube 12 is connected to the second end of the second bent tube 14 and is in communication with the second bent tube 14, and the second end of the second horizontal tube 12 is connected to the second flexible tube 30 and is in communication with the second flexible tube 30.

[0058] As can be seen, bending both ends of the rigid tube 10 into a preset shape achieves the preset position fixation of the installation path of the first flexible tube 20 and the second flexible tube 30. This not only avoids damage to the flexible tubes during installation and use due to random shaking, tangling or interference with other components, but also takes up little space and has a reasonable layout.

[0059] During the assembly of the aforementioned lightweight brake hose assembly: First, the first end of the rigid pipe 10 is connected to the first connector 21 of the first flexible hose 20, and the second end of the rigid pipe 10 is connected to the second connector 31 of the second flexible hose 30, forming a brake fluid transmission channel; second, the first adapter sleeve 41 is fixedly fitted onto the second end of the first flexible hose 20, protruding beyond the second end of the first flexible hose 20, and the mounting base 42 is fitted onto the part of the first adapter sleeve 41 protruding from the second end of the first flexible hose 20 through the first clearance hole 43 that matches the first adapter sleeve 41, completing the fixed connection between the first adapter 40 and the first flexible hose 20. The first through hole 44 on the mounting base 42 is aligned with the first mounting hole at the first mounting position on the brake pump body. The bolt shank passes through the first through hole 44 and is tightened into the first mounting hole, with the bolt head pressing against the mounting base 42. This allows the mounting base 42 to be detachably mounted on the brake pump body, achieving a stable connection between the first adapter 40 and the brake pump. This ensures that brake fluid can be smoothly transferred from the first hose 20 to the brake pump. Simultaneously, the second adapter sleeve 51 is fixedly fitted onto the second end of the second hose 30, protruding beyond it. Then, the first end of the bent adapter tube 52 is connected to the second adapter sleeve 51, ensuring… The two are connected, and then the second end of the bent adapter pipe 52 is connected to the mounting block 53. The second adapter pipe 50 is fitted into the preset position of the brake disc through the second clearance hole 54 in the middle of the mounting block 53, so that the second adapter pipe 50 is firmly connected to the brake disc, ensuring that the brake fluid can be smoothly transmitted from the second hose 30 to the brake disc, and realizing the effective transmission of braking pressure. Using the first rivet 22 protruding from the side of the first connector 21 near the rigid pipe 10, the first rivet 22 is inserted into the first rivet hole 61, and the first end of the connector 60 is firmly riveted to the first connector 21 by pressing and riveting. Similarly, the second connector 31 protruding from the side of the rigid pipe 10... The second rivet 32 ​​is inserted into the second rivet hole 62, and then the second end of the connecting seat 60 is fixed to the second connector 31 by pressing and riveting. Finally, the second through hole 63 on the connecting seat 60 is aligned with the second mounting hole at the second mounting position on the frame, so that the shank of the bolt passes through the second through hole 63 and is tightened into the second mounting hole, so that the bolt head presses against the connecting seat 60. At the same time, the third through hole 64 of the connecting seat 60 is aligned with the third mounting hole at the third mounting position on the frame, and the bolt passes through the third through hole 64 and is tightened into the third mounting hole, so that the bolt head presses against the connecting seat 60, thus completing the assembly of the brake pipe assembly.
