[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This disclosure claims priority to and the benefit of Chinese Patent Application No. 202222892105.5, filed on October 31, 2022. The entire contents of the above application are incorporated herein by reference.

[0002] The present disclosure relates to the field of vehicle technology, and more particularly to pipeline fastening members, vehicle systems and vehicles. [Background technology]

[0003] In the related art, the brake fluid pipeline of a vehicle is inserted into the cylinder block, so that the brake fluid flows through the brake fluid pipeline to the cylinder block.

[0004] However, in the related art, the dimensions of the pipeline that fits the cylinder block are fixed and have low adaptability. In addition, the brake fluid pipeline may rotate relative to the cylinder block. This results in a relatively poor connection reliability between the brake fluid pipeline and the cylinder block. Summary of the Invention

[0005] The present disclosure aims to solve, at least in part, one of the technical problems in the related art.

[0006] Therefore, an object of the present disclosure is to provide a pipeline fixing member that can effectively restrict the rotation of the pipeline relative to the cylinder block, thereby improving the reliability of the connection between the pipeline and the cylinder block.

[0007] Another object of the present disclosure is to provide a vehicle system.

[0008] It is yet another object of the present disclosure to provide a vehicle.

[0009] The pipeline fixing member provided by the present disclosure comprises: The fluid communication device includes a fixed member body having a flow path and first and second ports located at opposite ends of the flow path. The first port is adapted to be fixedly connected to a pipeline of a vehicle system. The second port is adapted to communicate with a cylinder block of the vehicle system. The fixed member body has a mounting portion fixedly connected to the cylinder block of the vehicle system.

[0010] According to the pipeline fixing member provided in the present disclosure, the pipeline communicates with the cylinder block through the use of the fixing member body. In this way, the reliability of the connection between the pipeline and the cylinder block is effectively improved, allowing brake fluid to flow stably to the cylinder block. The fixing member body is fixedly attached to the cylinder block through the use of the mounting portion. In this way, rotation of the fixing member body relative to the cylinder block is effectively restricted, thereby improving the stability and reliability of the connection between the pipeline and the cylinder block. Furthermore, rotation of the pipeline relative to the cylinder block is avoided, thereby ensuring a relatively stable flow of brake fluid in the fluid reservoir to the cylinder block. In addition, the assembly method between the pipeline fixing member and the cylinder block provided in the present disclosure is relatively simple, and the pipeline fixing member can be easily removed from the cylinder block and repaired. In this way, subsequent repair and replacement costs can be significantly reduced. Additionally, the pipeline fixing member provided in the present disclosure also has relatively high adaptability. The pipeline fixing member can be adapted to and adjusted for pipelines of different dimensions.

[0011] The vehicle system provided by the present disclosure comprises: a cylinder block, the cylinder block being the cylinder block of the vehicle system, the cylinder block defining an assembly hole; a sealing sleeve, the sealing sleeve being attached at the assembly hole; The system includes a pipeline and a pipeline fixing member, the pipeline fixing member being the aforementioned pipeline fixing member. A sealing sleeve is fitted over the pipeline fixing member to airtightly connect the pipeline fixing member to the cylinder block. The pipeline is a pipeline from the aforementioned vehicle system. The pipeline is attached to the pipeline fixing member to connect the pipeline fixing member to the cylinder block and the pipeline.

[0012] A vehicle provided by the present disclosure includes the vehicle system described above.

[0013] Additional aspects and advantages of the disclosure will be set forth in part in the description that follows, and in part will be obvious from the description, or may be learned by practice of the disclosure. [Brief explanation of the drawings]

Additionally, a feature defined as "first" or "second" can explicitly or implicitly include one or more features. In describing the present disclosure, unless otherwise specified, "several" means two or more.

[0017] It should be noted that in the description of the present disclosure, unless expressly stated and defined otherwise, the terms "attach," "communicate," and "connect" should be understood broadly. For example, the term "connect" can mean "fixedly connected," "detachably connected," or "integrally connected."

[0018] The following describes in detail the embodiments of the present disclosure. Examples of the embodiments are shown in the accompanying drawings, and the same or similar reference numerals throughout all the accompanying drawings indicate the same or similar components or components having the same or similar functions. The following embodiments described by referring to the accompanying drawings are illustrative and are used only to interpret the present disclosure and should not be understood as limitations on the present disclosure.

[0019] FIG. 1 is a schematic diagram of a pipeline fixing member 10 according to an embodiment of the present disclosure. FIG. 2 is a front view of the pipeline fixing member 10 according to an embodiment of the present disclosure. FIG. 3 is a cross-sectional view taken along the direction AA in FIG. 2. FIG. 4 is a schematic diagram of a vehicle system 1 according to an embodiment of the present disclosure. FIG. 5 is a partial cross-sectional view of the vehicle system 1 according to an embodiment of the present disclosure. The pipeline fixing member 10 according to an embodiment of the present disclosure will be described below with reference to FIGS. 1 to 5. The pipeline fixing member 10 includes a fixing member body 100. The fixing member body 100 has a flow path 110 and a first port (not shown) and a second port (not shown) located at opposite ends of the flow path 110. The first port is adapted to be fixedly connected to a pipeline 30 of the vehicle system 1. The second port is adapted to communicate with a cylinder block 20 of the vehicle system 1. The fixing member body 100 has an attachment portion 120 fixedly connected to the cylinder block 20 of the vehicle system 1.

[0020] In particular, the vehicle system 1 can be understood as a vehicle brake system. The cylinder block 20 of the vehicle system 1 can be understood as a hydraulic brake cylinder in the brake system. For example, the cylinder block 20 can be a mechanical brake cylinder connected to a pedal for a mechanical brake, or a drive-by-wire brake cylinder having a piston pump for a drive-by-wire brake. The cylinder block 20 is a pressure conversion component in the vehicle system 1. The cylinder block 20 can convert mechanical power transmitted from the vehicle's brake pedal into hydraulic pressure, which can then be transmitted to the brake wheel cylinders of the vehicle's four wheels through a pipeline 30. The brake wheel cylinders convert hydraulic energy into mechanical energy. Finally, resistance is generated by friction between the brake pads and brake discs, slowing the wheels or stopping the vehicle. The cylinder block 20 must be in communication with a fluid reservoir (not shown) that stores brake fluid in the vehicle, so that brake fluid can flow from the fluid reservoir to the cylinder block 20. The fixing member body 100 can be detachably connected to the cylinder block 20. In particular, the connection can be a threaded connection.

[0021] The fixing member body 100 is adapted to be attached to the cylinder block 20 of the vehicle system 1. The fixing member body 100 is configured to attach a pipeline 30 (the pipeline 30 of the vehicle system 1) and connect the cylinder block 20 to the pipeline 30. The fixing member body 100 has an attachment portion 120 that restricts rotation of the pipeline 30. The attachment portion 120 is adapted to be connected to the cylinder block 20. One end of the fixing member body 100 can be connected to the cylinder block 20, and the other end of the fixing member body 100 can be connected to the pipeline 30 of the fluid reservoir. With this arrangement, the pipeline 30 can be connected to the cylinder block 20 through the pipeline fixing member 10, so that brake fluid can flow to the cylinder block 20 through the pipeline 30 and the pipeline fixing member 10.

[0022] In some cases, the flow passage 110 may extend along the axial direction of the fixed member body 100 through opposite ends of the fixed member body 100. One end of the flow passage 110 may be in communication with the pipeline 30, and the other end of the flow passage 110 may be in communication with the cylinder block 20. With such an arrangement, brake fluid may flow from the pipeline 30 to the flow passage 110, through the flow passage 110, and into the cylinder block 20.

[0023] Furthermore, the mounting portion 120 can be fixedly connected to the fixing member body 100 through integral formation. The mounting portion 120 can be fixedly connected to the cylinder block 20 through a threaded connection, so that the mounting portion 120 can be fixedly attached relative to the cylinder block 20. With such an arrangement, the rotation of the fixing member body 100 relative to the cylinder block 20 can be effectively limited by the mounting portion 120. In this way, stability and reliability can be improved when the pipeline 30 is connected to the cylinder block 20. Furthermore, the rotation phenomenon of the pipeline 30 relative to the cylinder block 20 can be avoided, so that the brake fluid in the fluid reservoir can be ensured to flow relatively stably to the cylinder block 20. In addition, the assembly method between the mounting portion 120 and the cylinder block 20 provided in this embodiment of the present disclosure is relatively simple, and the mounting portion 120 and the cylinder block 20 can be easily removed from each other for repair. In this way, subsequent repair and replacement costs can be significantly reduced.

[0024] In some cases, the pipeline fixing member 10 may be integrally formed through injection molding by using an engineering plastic that is resistant to brake fluid. Materials such as nylon, PPS, or PPT may be selected as the engineering plastic, but this is not specifically defined in this embodiment of the present disclosure. Such an arrangement can effectively improve the manufacturing efficiency of the pipeline fixing member 10, reduce the production cost of the pipeline fixing member 10, and effectively reduce the weight of the pipeline fixing member 10.

[0025] According to the pipeline fixing member 10 provided in this embodiment of the present disclosure, the pipeline 30 communicates with the cylinder block 20 through the fixing member body 100. In this way, the reliability of the connection between the pipeline 30 and the cylinder block 20 can be effectively improved, allowing the brake fluid to flow stably to the cylinder block 20. By disposing the mounting portion 120 on the fixing member body 100, the rotation of the fixing member body 100 relative to the cylinder block 20 can be effectively restricted, thereby improving the stability and reliability when the pipeline 30 is connected to the cylinder block 20. Furthermore, the rotation phenomenon of the pipeline 30 relative to the cylinder block 20 is avoided, thereby ensuring that the brake fluid in the fluid reservoir flows relatively stably to the cylinder block 20. In addition, the assembly method between the mounting portion 120 and the cylinder block 20 provided in this embodiment of the present disclosure is relatively simple, and the mounting portion 120 and the cylinder block 20 can be easily removed from each other for repair. In this way, subsequent repair and replacement costs can be significantly reduced. In addition, the pipeline fixing member 10 provided in the present disclosure further has relatively high adaptability. The pipeline fixing member 10 can be adapted to and adjusted for pipelines 30 of different sizes.

[0026] 1 to 3 , in an embodiment of the present disclosure, the mounting portion 120 is disposed on the outer peripheral wall of the fixed member body 100. The mounting portion 120 may be disposed along the circumferential direction of the fixed member body 100. The mounting portion 120 may extend along the radial direction of the fixed member body 100 in a distal direction from the fixed member body 100. The fixed member body 100 may be fixedly connected to the cylinder block 20 through the mounting portion 120. With such an arrangement, rotation of the fixed member body 100 relative to the cylinder block 20 can be limited through the mounting portion 120, and as a result, rotation of the pipeline 30 relative to the cylinder block 20 is further limited.

[0027] 1 and 2 , in another embodiment of the present disclosure, the cross section of the mounting portion 120 is configured as an elliptical cross section. In particular, the mounting portion 120 may be fixedly connected to one end of the fixing member body 100 through integral formation. The cross section of the mounting portion 120 may be understood as a section of the mounting portion 120 along the radial direction of the one end of the fixing member body 100 fixedly connected to the mounting portion 120. The cross section of the mounting portion 120 may be elliptical or approximately elliptical. Such an arrangement may effectively improve the positioning accuracy of the fixing member body 100 attached to the cylinder block 20. In addition, the contact area between the fixing member body 100 and the cylinder block 20 may be effectively increased, resulting in improved connection strength and sealing performance between the fixing member body 100 and the cylinder block 20.

[0028] 1-3, in yet another embodiment of the present disclosure, the first port is configured as a hollow plug-in portion (not shown) that engages with a bayonet fit with the pipeline 30 of the vehicle system 1. With such an arrangement, the pipeline 30 of the vehicle system 1 can be fixedly attached to one end of the fixing member body 100 through the hollow plug-in portion.

[0029] 1-3 , in some embodiments of the present disclosure, the hollow plug-in portion is the first hollow shaft section 130. An outer wall of the first hollow shaft section 130 is configured to connect to an inner wall of the pipeline 30 of the vehicle system 1. In particular, one end of the first hollow shaft section 130 can be inserted into the pipeline 30. With such an arrangement, the pipeline 30 of the vehicle system 1 can be tightly fitted over the end of the first hollow shaft section 130, thereby further effectively improving the connection strength between the pipeline 30 and the first hollow shaft section 130.

[0030] 1-3, in a possible embodiment of the present disclosure, one end of the first hollow shaft section 130 distal from the mounting portion 120 has a limiting flange 131 that fits with the pipeline 30 of the vehicle system 1.

[0031] In particular, the end of the first hollow shaft section 130 remote from the mounting portion 120 may be configured to mount the pipeline 30 and be in communication with the pipeline 30. A limiting flange 131 may be disposed at the end of the first hollow shaft section 130 remote from the mounting portion 120. With such an arrangement, the pipeline 30 may be clamped to the fixation member body 100 through the limiting flange 131, fixedly connected thereto, and in communication with the fixation member body 100.

[0032] 1-3, in some embodiments of the present disclosure, the outer surface of the limiting flange 131 is configured as an inclined surface, and in the direction from the end of the first hollow shaft section 130 distal from the mounting portion 120 to the end of the first hollow shaft section 130 proximal to the mounting portion 120, the outer surface of the limiting flange 131 slopes toward the axial direction of the first hollow shaft section 130.

[0033] In particular, the limiting flange 131 may have a tapered structure. Any two opposing inclined edges of the limiting flange 131 may be disposed obliquely, forming an angle α between the two edges as shown in FIG. 2 . In addition, the angle α may range from 8 degrees to 12 degrees. In some cases, the angle α may be 10 degrees. With such an arrangement, the pipeline 30 may be attached relatively firmly to the end of the fixing member body 100. In this way, the sealing performance between the pipeline 30 and the fixing member body 100 may be significantly improved.

[0034] 1, 3, and 5, in yet another embodiment of the present disclosure, the stationary body member 100 has a second hollow shaft section 140. The second hollow shaft section 140 is configured as a second port. The first hollow shaft section 130 communicates with the second hollow shaft section 140. The second hollow shaft section 140 is adapted to engage with the cylinder block 20 of the vehicle system 1 in a bayonet fit.

[0035] In particular, the first hollow shaft section 130 and the second hollow shaft section 140 may be fixedly connected through integral formation. One end of the first hollow shaft section 130 remote from the second hollow shaft section 140 may be configured to attach the pipeline 30 and place the first hollow shaft section 130 in communication with the pipeline 30. The attachment portion 120 may be disposed at one end of the second hollow shaft section 140 remote from the first hollow shaft section 130. The second hollow shaft section 140 is connected to and in communication with the cylinder block 20 through the attachment portion 120. With such an arrangement, the pipeline 30 may be in communication with the cylinder block 20 through mutual cooperation of the first hollow shaft section 130 and the second hollow shaft section 140.

[0036] 3, in a further embodiment of the present disclosure, an included angle is formed between the axis of the first hollow shaft section 130 and the axis of the second hollow shaft section 140. The axis of the first hollow shaft section 130 is perpendicular to the axis of the second hollow shaft section 140.

[0037] In particular, the included angle between the central axis of the first hollow shaft section 130 and the central axis of the second hollow shaft section 140 may be 90 degrees. In other words, the first hollow shaft section 130 and the second hollow shaft section 140 may be perpendicular to each other. With such an arrangement, the axial length of the fixation member body 100 is effectively reduced, thereby preventing the fixation member body 100 from occupying excessive operating space.

[0038] 1 and 2, in an optional embodiment of the present disclosure, the attachment portion 120 is disposed on the second hollow shaft section 140 and is integrally formed therewith.

[0039] In particular, the attachment portion 120 may be disposed through integral formation at one end of the second hollow shaft section 140 remote from the first hollow shaft section 130. Such an arrangement may effectively improve the production and manufacturing efficiency of the second hollow shaft section 140.

[0040] 1 and 2, in an optional embodiment of the present disclosure, the mounting portion 120 is disposed on the outer circumferential wall of the second hollow shaft section 140. The mounting portion 120 has a plurality of mounting holes 121. The plurality of mounting holes 121 are configured for assembly of the cylinder block 20. The plurality of mounting holes 121 are symmetrical with respect to the central axis of the second hollow shaft section 140.

[0041] Optionally, the mounting portion 120 may be provided with multiple mounting holes 121, for example, two, three, four, etc., which is not specifically defined in this embodiment of the present disclosure. The following embodiment will be described by using two mounting holes 121 as an example. The mounting holes 121 may be circular in shape. The axial direction of the mounting holes 121 may be parallel to the axial direction of the second hollow shaft section 140. The mounting holes 121 may be through holes or threaded holes extending through the mounting portion 120. The two mounting holes 121 may be distributed on both sides of the mounting portion 120 symmetrically about the center, and the center of symmetry of the two mounting holes 121 may coincide with the central axis of the second hollow shaft section 140. The mounting portion 120 may be fixedly attached to the cylinder block 20 through bolts (not shown) passing through the mounting holes 121. With such an arrangement, the second hollow shaft section 140 can be stably connected to the cylinder block 20, and the circumferential sealing performance between the second hollow shaft section 140 and the cylinder block 20 can be relatively high.

[0042] Furthermore, a plurality of counterbore threaded holes (not shown) may be provided in the cylinder block 20, and the plurality of counterbore threaded holes may be provided in one-to-one correspondence with the plurality of mounting holes 121. Bolts (not shown) may pass through the mounting holes 121 and be threaded into the counterbore threaded holes, so that the second hollow shaft section 140 may be fixedly connected to the cylinder block 20 through the bolt connection.

[0043] Further referring to FIG. 3, in some embodiments of the present disclosure, the outer peripheral wall of the second hollow shaft section 140 has an annular step structure 141, which is positioned adjacent to the first hollow shaft section 130, such that a step surface on the outer peripheral wall of the second hollow shaft section 140 is formed.

[0044] In particular, the central axis of the annular step structure 141 may coincide with the central axis of the second hollow shaft section 140. The outer diameter of the annular step structure 141 varies along the axial direction of the second hollow shaft section 140. In other words, the outer diameter of the annular step structure 141 at one end of the second hollow shaft section 140 proximal to the first hollow shaft section 130 is larger than the outer diameter of the annular step structure 141 at the other end of the second hollow shaft section 140 remote from the first hollow shaft section 130. With this arrangement, the annular step structure 141 forms an annular step surface 142 extending along the radial direction of the second hollow shaft section 140. The annular step surface 142 may be configured to improve axial sealing performance between the fixing member body 100 and the cylinder block 20.

[0045] 4 and 5 , a vehicle system 1 provided according to an embodiment of the present disclosure includes a cylinder block 20, where the cylinder block 20 corresponds to the cylinder block 20 of the vehicle system 1 in the previous embodiment and defines an assembly hole 21; a sealing sleeve 40, where the sealing sleeve is attached to the assembly hole 21; and a pipeline 30 and a pipeline fixing member 10, where the pipeline fixing member 10 corresponds to the pipeline fixing member 10 in the previous embodiment. The sealing sleeve 40 is fitted over the pipeline fixing member 10 to airtightly connect the cylinder block 20 to the pipeline fixing member 10. The pipeline 30 corresponds to the pipeline 30 of the vehicle system 1 in the previous embodiment. The pipeline 30 is attached to the pipeline fixing member 10 and connects the pipeline fixing member 10 to the cylinder block 20 and the pipeline 30. The specific structure and working principle of the pipeline fixing member 10 have already been explained and described in detail in the previous embodiments, and the details will not be repeated here.

[0046] Optionally, the cylinder block 20 may be the cylinder block 20 of the vehicle system 1 in the previous embodiment. The cylinder block 20 has an assembly hole 21 communicating with the interior of the cylinder block 20. The assembly hole 21 may be configured to mount the pipeline fixing member 10. The sealing sleeve 40 may be an annular sealing member. The sealing sleeve 40 may be accommodated in the assembly hole 21 through an interference fit. One end of the pipeline fixing member 10 is accommodated in the assembly hole 21, and the sealing sleeve 40 may be fitted over the outer wall of the pipeline fixing member 10. With such an arrangement, the axial and radial sealing performance between the pipeline fixing member 10 and the assembly hole 21 can be significantly improved through the cooperation of the sealing sleeve 40 and the annular step structure 141, thereby preventing air or brake fluid from leaking through the gap between the pipeline fixing member 10 and the assembly hole 21.

[0047] Furthermore, the pipeline 30 can be attached to the other end of the pipeline fixing member 10 remote from the cylinder block 20, so that the pipeline 30, the pipeline fixing member 10, and the assembly hole 21 are sequentially in communication with each other. Such an arrangement allows the brake fluid contained in the fluid reservoir to flow through the pipeline 30 and the pipeline fixing member 10 to the cylinder block 20.

[0048] The vehicle provided by the embodiment of the present disclosure includes the vehicle system 1 in the above-described embodiment. The specific structure and operation principle of the vehicle system 1 have already been explained and described in detail in the above-described embodiment, and the details will not be described again here.
