[0002] The main function of the automobile braking system is to slow down or even stop a moving car, and to keep a stopped car stationary. The automobile braking system mainly uses brake fluid to brake the car. The brake fluid is transported through the brake pipe. The brake pipe includes a brake pipe and a brake hose. The automobile brake pipe mainly refers to a pipe made of metal material for transmitting brake fluid. Its two ends are connected to other components of the automobile braking system (such as the brake master cylinder, brake wheel cylinder, etc.).

[0003] The brake hard pipe includes a spiral pipe section, which is very easy to deform during transportation and the vibration of the whole vehicle. In addition, since the brake hard pipe is relatively long, in order to facilitate transportation and assembly, the brake hard pipe is disconnected from the middle to become two sections of sub-hard pipes. During assembly, the two sections of sub-hard pipes are connected through a hard pipe connecting assembly to form a passage, and the hard pipe connecting assembly is connected to the body or frame of the vehicle to fix and support the sub-hard pipe. When the sub-hard pipe is connected to the hard pipe connecting assembly, due to processing errors and assembly errors in the hard pipe, the hard pipe connecting assembly and other components, the misalignment of the sub-hard pipe and the hard pipe connecting assembly is large, which makes the operation of docking the sub-hard pipe and the hard pipe connecting assembly more difficult. In addition, when the misalignment of the docking of the sub-hard pipe and the hard pipe connecting assembly is large, forcibly docking the sub-hard pipe and the hard pipe connecting assembly will cause greater stress in the mating part between the sub-hard pipe and the hard pipe connecting assembly, which will easily cause leakage and other problems in the mating part.

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] The following combination Figures 1 to 7 , a hard pipe connection component 1, a brake hard pipe assembly 3 and a vehicle provided in the present application are described in detail.

[0035] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of a hard pipe connection assembly 1 provided in an exemplary embodiment of the present disclosure. The embodiment of the present application provides a hard pipe connection assembly 1. The hard pipe connection assembly 1 includes a pipe joint 21 and an adjusting member 22. The pipe joint 21 has two pipe interfaces 211. The adjusting member 22 has a first end 221 and a second end 222. The first end 221 is connected to the pipe joint 21. The first end 221 is movable relative to the second end 222.

[0036] It can be understood that the first end 221 and the second end 222 can be located at two ends of the adjusting member 22 respectively, and the second end 222 is configured to be connected to the frame or body of the vehicle.

[0037] It is understood that in the embodiments of the present application, the connection may be a direct connection or an indirect connection through an intermediate medium. The connection may be a fixed connection or a detachable connection. For example, the first end 221 may be directly connected to the pipe joint 21 or indirectly connected through an intermediate medium. The second end 222 may be directly connected to the body or frame of the vehicle or indirectly connected through an intermediate medium.

[0038] Exemplarily, the adjusting member 22 includes, but is not limited to, a connecting rod mechanism, a slider rail component, a spring, an elastic rubber component, and an elastic airbag. For example, when the adjusting member 22 is a connecting rod mechanism, it may include a first connecting rod and a second connecting rod, one end of the first connecting rod is the second end 222, and is hinged to the body or frame of the vehicle, and the other end is hinged to one end of the second connecting rod. The other end of the second connecting rod is the first end 221, and is hinged to the pipe joint 21. For another example, when the adjusting member 22 is a slider rail component, it includes a slide rail and a slider, the slide rail is fixed to the body or frame of the vehicle, and the slider is slidably set on the slide rail. The slider is the first end 221, and the slide rail is the second end 222.

[0039] When the hard pipe connection assembly 1 connects two sub-hard pipes, one end of one sub-hard pipe is connected to one end of the pipe joint 21, and the other end is connected to the brake end of the vehicle (such as the brake master cylinder, the brake master cylinder). One end of the other sub-hard pipe is connected to the other end of the pipe joint 21, and the other end is connected to the brake (such as the brake wheel cylinder, the brake caliper).

[0040] During assembly, the two sub-hard pipes can be connected to the pipe joint 21 first, and then the adjusting member 22 can be fixed to the vehicle body or frame. In order to ensure the connection torque between the sub-hard pipe and the pipe joint 21, a torque wrench can be used to tighten the connection between the sub-hard pipe and the pipe joint 21.

[0041] In this embodiment, by connecting the adjusting member 22 to the pipe joint 21, the adjustable size of the pipe joint 21 relative to the vehicle body or frame can be improved, so as to compensate for the processing errors and assembly errors of the sub-hard pipe, the hard pipe connection assembly 1 and other components through the elastic deformation of the adjusting member 22. In this way, the smoothness of the docking between the sub-hard pipe and the pipe joint 21 and the ease of operation of the connection between the adjusting member 22 and the vehicle body or frame can be improved. Finally, the stress state of the connection part between the sub-hard pipe and the pipe joint 21 can be improved to improve the reliability of the connection between the sub-hard pipe and the hard pipe connection assembly 1.

[0042] In addition, by connecting the adjusting member 22 to the pipe joint 21, the elastic properties of the adjusting member 22 can buffer the vibration of the pipe joint 21, thereby improving the stability of the connection between the sub-hard pipe and the pipe joint 21 and improving the durability of the pipeline of the relevant braking system.

[0043] Furthermore, by connecting the adjusting member 22 to the pipe joint 21 to improve the stress state of the connection between the rigid tube 31 and the pipe joint 21, the adverse effects of processing errors, assembly errors, and transportation deformations on the torque of the connection between the sub-rigid tube and the pipe joint 21 can be reduced, so as to ensure the accuracy of the torque of the connection between the sub-rigid tube and the pipe joint 21. The assembly error refers to the deviation between the relative position, fitting accuracy, etc. between the components and the design requirements caused by various factors during the product assembly process. For example, the assembly error can be the unavoidable error of the assembly of the pipe joint 21 with the vehicle body or frame, and can also be the sum of the error chains generated by the components involved in the installation of the pipe joint 21.

[0044] See also Figure 1 In some embodiments, the hard pipe connection assembly 1 further includes a first plate 23. The first plate 23 is provided with a threaded hole 231. The pipe joint 21 is passed through the threaded hole 231 and threadedly connected with the threaded hole 231. The first end 221 is connected to the first plate 23.

[0045] It can be understood that in order to facilitate the connection between the pipe joint 21 and the sub-rigid pipe, both ends of the pipe joint 21 are located outside the threaded hole 231.

[0046] Specifically, the adjusting member 22 can be connected to the first plate 23 by adhesive bonding, welding, riveting, hanging, clamping or screwing.

[0047] In this embodiment, through the above-mentioned arrangement, on the one hand, the pipe joint 21 can be rotated to adjust the position of the pipe joint 21 relative to the first plate 23, thereby improving the adjustability of the rotating pipe joint 21, and further compensating for the processing errors and assembly errors of components such as the sub-rigid pipe and the rigid pipe connecting assembly 1; on the other hand, the pipe joint 21 is detachably connected to the adjusting member 22 through the first plate 23, thereby improving the maintenance operability of the pipe joint 21.

[0048] See also Figure 1 In some embodiments, the hard pipe connection assembly 1 further includes a second plate 24. The second end 222 is connected to the second plate 24.

[0049] It will be appreciated that the second plate 24 is configured to be coupled to a vehicle.

[0050] It can be understood that the first end 221 and the second end 222 are respectively located at two ends of the adjusting member 22 .

[0051] In this embodiment, by providing the second plate 24 , the hard pipe 31 connector 21 assembly can be fixed to the vehicle body or frame through the second plate 24 , thereby improving the operability of fixing the hard pipe 31 connector 21 assembly.

[0052] See also Figure 1 and Figure 2 , Figure 2 yes Figure 1 The side view of the hard pipe connection assembly 1 shown in FIG. 1 shows that in some embodiments, a first through hole 241 is provided on the second plate 24. The first plate 23 is disposed in the first through hole 241. In this way, the connection between the first plate 23 and the pipe joint 21 can be protected by the second plate 24 to prevent the connection between the first plate 23 and the pipe joint 21 from being damaged due to accidental impact.

[0053] See also Figure 3 Figure 4 Figure 3 is a schematic structural diagram of another hard pipe connection assembly 1 provided in an exemplary embodiment of the present disclosure, Figure 4 yes Figure 3 The side view of the hard pipe connection assembly 1 is shown. In other embodiments, the second plate 24 is provided with a first through hole 241. Along the axis of the first through hole 241, the first plate 23 and the second plate 24 are spaced apart. Part of the pipe joint 21 is located in the first through hole 241.

[0054] In this embodiment, through the above arrangement, on the one hand, the limit of the second plate 24 on the radial movement of the first plate 23 in the first through hole 241 can be reduced, so that the movable range of the first plate 23 in the radial direction of the first through hole 241 is larger, so as to improve the position adjustability of the first plate 23, and on the other hand, the adjusting member 22 can not only be adjusted along its own telescopic direction, but also help the first plate 23 to move along the axial direction of the pipe joint 21. In this way, the adjustability of the pipe joint 21 can be improved, and then the processing errors and assembly errors of the sub-hard pipes, the hard pipe connecting assembly 1 and other components can be compensated, which helps to improve the reliability of the connection between the sub-hard pipes.

[0055] See also Figure 1 or Figure 3 In some embodiments, there are multiple adjusting members 22. The multiple adjusting members 22 are arranged at intervals along the circumference of the first through hole 241. In this way, not only the reliability of the connection between the first plate 23 and the pipe joint 21 can be improved, but also the force uniformity between the first plate 23 and the pipe joint 21 can be improved, so as to improve the reliability of the hard pipe connection assembly 1.

[0056] See also Figure 5 , Figure 5 2 is a schematic diagram of the positional relationship between the adjusting member 22 and the Z direction provided in an exemplary embodiment of the present disclosure. In some embodiments, the adjusting member 22 is an elastic member. The angle between the telescopic direction of at least part of the adjusting member 22 and the Z direction of the vehicle is an acute angle α.

[0057] See also Figure 4 In some other embodiments, the adjusting member 22 is an elastic member. The angle between the telescopic direction of at least part of the adjusting member 22 and the X direction of the vehicle is an acute angle β.

[0058] See also Figure 4 and Figure 5 In other embodiments, the adjusting member 22 is an elastic member. In this way, during the driving of the vehicle, the adjusting member 22 can absorb vibration, especially vibration in the X and Z directions, to avoid torque attenuation and loosening of the pipe joint 21 caused by vibration during the driving of the vehicle, thereby improving the reliability of the connection between the hard pipes.

[0059] Furthermore, the adjusting member 22 is an elastic member, which can also effectively reduce the deformation of the spiral pipe section of the hard pipe caused by the vibration of the whole vehicle, so as to improve the reliability of the hard pipe.

[0060] Specifically, the angle between the extension direction of at least part of the adjusting member 22 and the Z direction of the vehicle is an acute angle α, and the angle between the extension direction of at least part of the adjusting member 22 and the X direction of the vehicle is an acute angle β.

[0061] The Z direction of the vehicle is a direction perpendicular to the ground, and the X direction of the vehicle is a forward direction of the vehicle.

[0062] It can be understood that during the vibration process of the brake hard pipe 31, most of the vibrations are the Z-direction vibration and X-direction vibration of the vehicle. The second plate 24 is fixed to the body or frame of the vehicle. When the vehicle moves, the vibration is transmitted to the adjustment member 22 through the second plate 24. Through the above arrangement, the adjustment member 22 can adapt to vibrations in all directions, that is, it can decompose the vibration, especially the Z-direction vibration that occurs more frequently. In this way, the vibration buffering performance of the adjustment member 22 on the pipe joint 21 can be improved, so as to improve the connection stability between the sub-hard pipe and the pipe joint 21, and to improve durability.

[0063] See also Figure 5 In some embodiments, there are four adjusting members 22, and the four adjusting members 22 are evenly distributed along the circumferential interval of the first through hole 241. In this way, the force uniformity of the pipe joint 21, the first plate 23 and the second plate 24 can be improved, thereby improving the force state of the hard pipe connection assembly 1, so as to improve the reliability of the hard pipe connection assembly 1.

[0064] Specifically, the angle between the extension direction of the four adjusting members 22 and the X direction of the vehicle is an acute angle β, and the angle between the extension direction of the four adjusting members 22 and the Z direction of the vehicle is an acute angle α. The first through hole 241 is a rectangular hole, one hole wall of the rectangular hole is parallel to the horizontal plane, and the other hole wall is perpendicular to the horizontal plane, and the four adjusting members 22 correspond to the four corners of the rectangular hole one by one.

[0065] It can be understood that the vehicle mainly experiences Z-axis vibration and X-axis vibration during driving.

[0066] The four adjusting members 22 are arranged in one-to-one correspondence with the four corners of the first through hole 241, that is, the four adjusting members 22 are located in the diagonal direction of the first through hole 241. In this way, when the vehicle generates Z-direction vibration or X-direction vibration, the diagonally arranged adjusting members 22 can decompose the vibration force, that is, the four adjusting members 22 can absorb, store and reduce the Z-direction vibration and the X-direction vibration. In this way, the limitation of the vibration reduction of the adjusting member 22 can be avoided, so that the adjusting member 22 can reduce the vibration in multiple directions, so that the setting of the adjusting member 22 is more in line with the movement process of the whole vehicle and adapts to various movement states of the vehicle.

[0067] In addition, the first plate 23 and the second plate 24 are arranged at intervals along the axis of the first through hole 241, so that the first plate 23 is located in the first through hole 241, that is, the adjusting member 22 can be located outside the first through hole 241. In this way, the movement of the adjusting member 22 is not hindered by the second plate 24, and the range of vibration that can be buffered by the adjusting member 22 can be increased, so as to improve the adaptability of the hard pipe connection assembly 1.

[0068] See also Figure 1In some embodiments, a plurality of second through holes 242 are provided on the second plate 24. In this way, during the vibration buffering process of the adjusting member 22, the porous structure formed by the plurality of second through holes 242 can release the vibration energy at a faster amplitude, thereby reducing the vibration amplitude and vibration frequency of the adjusting member 22 and the pipe joint 21.

[0069] In addition, the porous structure can greatly reduce the resonance phenomenon caused by the vibration frequency of the structure itself being consistent with the vibration frequency of the vehicle, making the structure more stable.

[0070] See also Figure 1 In some embodiments, the second plate 24 includes a first sub-plate 243 and a second sub-plate 244. The first sub-plate 243 is perpendicular to the axis of the pipe joint 21. The first sub-plate 243 is connected to the adjusting member 22. The second sub-plate 244 is connected to the first sub-plate 243 at an angle. The second end 222 is connected to the first sub-plate 243.

[0071] Specifically, the first through hole 241 is disposed on the first sub-plate 243 .

[0072] The second sub-plate 244 is configured to be connected to the vehicle. Specifically, the second sub-plate 244 is fastened to the vehicle body or the frame by bolts.

[0073] Exemplarily, a plate body is bent to form the connected first sub-plate 243 and second sub-plate 244 , or the first sub-plate 243 and second sub-plate 244 that are independent of each other are welded to form the second plate 24 .

[0074] It can be understood that the first plate 23 and the second plate 24 are arranged at an angle, and one end of the first plate 23 is connected to one end of the second plate 24. The angle between the first plate 23 and the second plate 24 can be adaptively adjusted according to the angle between the plane on which the second plate 24 is installed on the vehicle body or frame and the axis of the pipe joint 21.

[0075] In this embodiment, through the above arrangement, on the basis of realizing the connection between the second plate 24 and the vehicle body or the frame and the connection between the second plate 24 and the adjusting member 22, the second plate 24 has a simple structure and is easy to manufacture.

[0076] See also Figure 1 In some embodiments, a reinforcing rib 25 is provided between the first sub-plate 243 and the second sub-plate 244. In this way, the strength of the connection portion between the first sub-plate 243 and the second sub-plate 244 can be improved, so as to improve the structural reliability of the hard pipe connection assembly 1.

[0077] In some embodiments, the adjusting member 22 is provided with a plurality of third through holes 223. Thus, during the vibration buffering process of the adjusting member 22, the porous structure formed by the plurality of third through holes 223 can release vibration energy at a faster amplitude, thereby reducing the vibration amplitude and vibration frequency of the adjusting member 22 and the pipe joint 21.

[0078] In addition, the porous structure can greatly reduce the resonance phenomenon caused by the vibration frequency of the structure itself being consistent with the vibration frequency of the vehicle, making the structure more stable.

[0079] It can be understood that when the adjusting member 22 is an elastic member, the third through hole 223 provided on the adjusting member 22 should not reduce the durability of the elastic member, and the third through hole 223 needs to be provided under the premise that its strength modality allows. Therefore, the elastic member can be thickened, or only the part of the elastic member where the third through hole 223 is provided can be partially thickened to improve the strength of the elastic member and meet the durability requirements of the elastic member.

[0080] See also Figure 1 In some embodiments, the adjusting member 22 is a coil spring. In this way, the adjusting member 22 can have good elastic deformation performance. Moreover, the coil spring can withstand a large amount of cyclic loads without fatigue damage and has high reliability.

[0081] See also Figure 6 and Figure 7 , Figure 6 is a structural schematic diagram of a brake hard pipe assembly 3 provided in an exemplary embodiment of the present disclosure, Figure 7 is a structural schematic diagram of another brake hard pipe assembly 3 provided in an exemplary embodiment of the present disclosure. Accordingly, an embodiment of the present application also provides a brake hard pipe assembly 3. The brake hard pipe assembly 3 includes a hard pipe 31 and the aforementioned hard pipe connection assembly 1. The hard pipe 31 includes a first sub-hard pipe 311 and a second sub-hard pipe 312. One end of the first sub-hard pipe 311 is connected to one end of the pipe joint 21. One end of the second sub-hard pipe 312 is connected to the other end of the pipe joint 21.

[0082] Specifically, one end of the first sub-rigid tube 311 is connected to one pipe interface 211 of the pipe joint 21 . One end of the second sub-rigid tube 312 is connected to the other pipe interface 211 of the pipe joint 21 .

[0083] In this embodiment, by adopting the hard pipe connection assembly 1 provided in some embodiments of the present application, the adjustable size of the pipe joint 21 relative to the vehicle body or frame can be improved, so as to compensate for the processing errors and assembly errors of the sub-hard pipe, the hard pipe connection assembly 1 and other components through the elastic deformation of the adjustment member 22. In this way, the smoothness of the docking between the sub-hard pipe and the pipe joint 21 and the ease of operation of the connection between the adjustment member 22 and the vehicle body or frame can be improved. Finally, the stress state of the connection part between the sub-hard pipe and the pipe joint 21 can be improved to improve the reliability of the connection between the sub-hard pipe and the hard pipe connection assembly 1.

[0084] The embodiment of the present application also provides a vehicle, which includes the aforementioned brake hard pipe assembly 3. The end of the adjustment member 22 away from the pipe joint 21 is connected to the vehicle body or the vehicle frame. Specifically, the second sub-plate 244 is connected to the vehicle body or the vehicle frame.

[0085] In this embodiment, by adopting the brake hard pipe assembly 3 provided in some embodiments of the present application, the adjustable size of the pipe joint 21 relative to the vehicle body or frame can be improved, so as to compensate the processing errors and assembly errors of the sub-hard pipe, the hard pipe connection assembly 1 and other components through the elastic deformation of the adjustment member 22. In this way, the smoothness of the docking between the sub-hard pipe and the pipe joint 21 can be improved, and the ease of operation of the connection between the adjustment member 22 and the vehicle body or frame can be improved.
