TECHNICAL FIELD
[0001] The present application relates to the technical field of automobiles, in particular to a hard pipe connecting assembly, a brake hard pipe assembly and a vehicle. BACKGROUND
[0002] The main function of an automobile brake system is to slow down or even stop a moving automobile and keep a stopped automobile in a stationary state. The automobile brake system mainly realizes automobile braking through brake fluid. The brake fluid is transported through a brake pipeline. The brake pipeline includes a brake hard pipe and a brake soft pipe. The automobile brake hard pipe mainly refers to a pipeline made of metal material for transmitting brake fluid. The two ends of the automobile brake hard pipe are connected with other components (such as a brake master cylinder and a brake wheel cylinder) of the automobile brake system.
[0003] The brake hard pipe includes a spiral pipe segment, which is prone to deformation during transportation and vehicle vibration.

During assembly, the two sub-hard pipes are connected by a hard pipe connecting assembly to form a passage, and the hard pipe connecting assembly is connected with the vehicle body or frame to fix and support the sub-hard pipes. When the sub-hard pipes are connected with the hard pipe connecting assembly, due to the machining errors and assembly errors of the hard pipe and the hard pipe connecting assembly, the misalignment of the sub-hard pipes and the hard pipe connecting assembly when they are connected is large, which leads to a large operation difficulty of the connection of the sub-hard pipes and the hard pipe connecting assembly. In addition, when the misalignment of the sub-hard pipes and the hard pipe connecting assembly is large, forcibly connecting the sub-hard pipes and the hard pipe connecting assembly will cause a large stress between the sub-hard pipes and the hard pipe connecting assembly, which leads to a problem that the connection position between the sub-hard pipes and the hard pipe connecting assembly is prone to leakage.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor are within the protection scope of the present application.
[0034] The following will be described in detail Figures 1 to 7 , a hard pipe connecting assembly 1, a brake hard pipe assembly 3 and a vehicle provided by the present application.
[0035] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of the hard pipe connecting assembly 1 provided in the exemplary embodiments of the present disclosure. The embodiments of the present application provide a hard pipe connecting assembly 1. The hard pipe connecting assembly 1 comprises 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 with 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 with the vehicle frame or vehicle body.
[0037] It can be understood that in the embodiments of the present application, the connection can be direct connection or indirect connection through an intermediate medium. The connection can be fixed connection or detachable connection. For example, the first end 221 can be directly connected with the pipe joint 21, or indirectly connected through an intermediate medium. The second end 222 can be directly connected with the vehicle body or vehicle frame, 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 member, a spring, an elastic rubber member, and an elastic air bag. For example, when the adjusting member 22 is a connecting rod mechanism, it can include a first connecting rod and a second connecting rod. One end of the first connecting rod is the second end 222 and is hingedly connected with the vehicle body or vehicle frame, and the other end is hingedly connected with one end of the second connecting rod. The other end of the second connecting rod is the first end 221 and is hingedly connected with the pipe joint 21. For another example, when the adjusting member 22 is a slider rail member, it includes a slide rail and a slider. The slide rail is fixed on the vehicle body or vehicle frame, and the slider is slidingly arranged 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 connecting assembly 1 connects two sub hard pipes, one end of one sub hard pipe is connected with one end of the pipe joint 21, and the other end is connected with a brake end (such as a brake master cylinder or a brake master cylinder) of the vehicle. The other end of the other sub hard pipe is connected with the other end of the pipe joint 21, and the other end is connected with a brake (such as a brake cylinder or a brake caliper).
[0040] During assembly, the two sub hard pipes can be connected with the pipe joint 21 first, and then the adjusting member 22 is fixed on 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 with the pipe joint 21, the adjustable size of the pipe joint 21 relative to the vehicle body or frame can be improved, so that the processing error and assembly error of the sub hard pipe, the hard pipe connecting assembly 1 and other components can be compensated by the elastic deformation of the adjusting member 22. In this way, the smoothness of the connection 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 between the sub hard pipe and the pipe joint 21 can be improved, and the reliability of the connection between the sub hard pipe and the hard pipe connecting assembly 1 can be improved.
[0042] In addition, by connecting the adjusting member 22 with the pipe joint 21, the vibration of the pipe joint 21 can be buffered by the elastic performance of the adjusting member 22, so that the stability of the connection between the sub hard pipe and the pipe joint 21 can be improved, and the durability of the pipe of the related brake system can be improved.
[0043] Furthermore, by connecting the adjusting member 22 with the pipe joint 21 to improve the stress state of the connection between the hard pipe 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 hard pipe and the pipe joint 21 can be reduced, so that the accuracy of the torque of the connection between the sub hard pipe and the pipe joint 21 can be ensured. The assembly error refers to the deviation between the relative position and the fitting accuracy of the components and the design requirements due to various factors during product assembly. For example, the assembly error can be the inevitable error of the pipe joint 21 assembled with the vehicle body or frame, and can also be the sum of the error chain generated by each component involved in the installation of the pipe joint 21.
[0044] Please refer to Figure 1 In some embodiments, the hard pipe connecting assembly 1 further comprises a first plate 23. The first plate 23 is provided with a threaded hole 231. The pipe joint 21 is arranged in the threaded hole 231 and is threadedly connected with the threaded hole 231. The first end 221 is connected with the first plate 23.
[0045] It can be understood that in order to facilitate the connection of the pipe joint 21 with the sub hard pipe, both ends of the pipe joint 21 are located outside the threaded hole 231.
[0046] Specifically, the adjusting member 22 can be glued, welded, riveted, hanged, clamped or screwed with the first plate 23.
[0047] In the embodiment, through the above 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, so that the adjustability of the pipe joint 21 can be improved, and thus the machining error and assembly error of the sub-hard pipe, the hard pipe connecting assembly 1 and other components can be compensated; on the other hand, the pipe joint 21 is detachably connected with the adjusting member 22 through the first plate 23, so that the maintenance operability of the pipe joint 21 can be improved.
[0048] Referring to Figure 1 In some embodiments, the hard pipe connecting assembly 1 further comprises a second plate 24. The second end 222 is connected with the second plate 24.
[0049] It can be understood that the second plate 24 is configured to be connected with the 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 the embodiment, by arranging the second plate 24, the pipe joint 21 assembly can be fixed to the vehicle body or frame through the second plate 24, so that the operability of fixing the hard pipe connecting assembly 1 can be improved.
[0052] Referring to Figure 1 and Figure 2 , Figure 2 is Figure 1 the side view of the hard pipe connecting assembly 1 shown in FIG. 1. In some embodiments, the second plate 24 is provided with a first through hole 241. The first plate 23 is arranged in the first through hole 241. In this way, the connection part between the first plate 23 and the pipe joint 21 can be protected by the second plate 24 to avoid damage to the connection part between the first plate 23 and the pipe joint 21 due to accidental impact.
[0053] Referring to Figure 3 Figure 4 Figure 3 is a structural schematic view of another hard pipe connecting assembly 1 provided in an exemplary embodiment of the present disclosure, Figure 4 is Figure 3 the side view of the hard pipe connecting assembly 1 shown in FIG. 1. In some embodiments, the second plate 24 is provided with a first through hole 241. The first plate 23 and the second plate 24 are arranged in a spaced manner along the axis of the first through hole 241. Part of the pipe joint 21 is located in the first through hole 241.
[0054] In the embodiment, through the above arrangement, on the one hand, the second plate 24 can reduce the limit of the first plate 23 moving in the radial direction of the first through hole 241, 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 adjustable of the first plate 23, on the other hand, the adjusting part 22 can be adjusted not only in the self stretching 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 machining error and assembly error of the sub hard pipe, the hard pipe connecting assembly 1 and the like can be compensated, which helps to improve the reliability of the connection between the sub hard pipes.
[0055] Referring to Figure 1 or Figure 3 In some embodiments, the adjusting part 22 is provided in plurality. The plurality of adjusting parts 22 are arranged in the circumferential direction 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 stress uniformity between the first plate 23 and the pipe joint 21 can be improved, so as to improve the reliability of the hard pipe connecting assembly 1.
[0056] Referring to Figure 5 , Figure 5 is a schematic view of the position relationship between the adjusting part 22 and the Z direction in the exemplary embodiment of the present disclosure. In some embodiments, the adjusting part 22 is an elastic part. The included angle between the stretching direction of at least part of the adjusting part 22 and the Z direction of the vehicle is an acute angle α.
[0057] Referring to Figure 4 In other embodiments, the adjusting part 22 is an elastic part. The included angle between the stretching direction of at least part of the adjusting part 22 and the X direction of the vehicle is an acute angle β.
[0058] Referring to Figure 4 and Figure 5 In other embodiments, the adjusting part 22 is an elastic part. In this way, during the driving of the vehicle, the adjusting part 22 can absorb the vibration, especially the vibration in the X direction and the Z direction, so as to avoid the torque attenuation and loosening of the pipe joint 21 due to the vibration during the driving of the vehicle, so as to improve the reliability of the connection between the hard pipes.
[0059] In addition, the adjusting part 22 is an elastic part, which can 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 included angle between the stretching direction of at least part of the adjusting part 22 and the Z direction of the vehicle is an acute angle α, and the included angle between the stretching direction of at least part of the adjusting part 22 and the X direction of the vehicle is an acute angle β.
[0061] Among them, the Z direction of the vehicle is the direction perpendicular to the ground, and the X direction of the vehicle is the forward direction of the vehicle.
[0062] It is understood that during the vibration of the brake rigid pipe 31, most of the vibration is in the Z and X directions of the vehicle. The second plate 24 is fixed to the vehicle body or frame. When the vehicle moves, the vibration is transmitted to the adjusting member 22 through the second plate 24. Through the above arrangement, the adjusting member 22 can adapt to vibration in all directions, that is, it can decompose the vibration, especially the Z-direction vibration that occurs most frequently. In this way, the vibration buffering performance of the adjusting member 22 on the pipe joint 21 can be improved, which is conducive to improving the connection stability between the brake rigid pipe and the pipe joint 21 and improving durability.
[0063] Please see Figure 5 In some embodiments, there are four adjusting members 22, which are evenly distributed circumferentially along the first through hole 241. This improves the uniformity of force on the pipe joint 21, the first plate 23, and the second plate 24, thereby improving the stress state of the rigid pipe connection assembly 1 and enhancing its reliability.
[0064] Specifically, the angle between the extension / retraction 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 / retraction 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, with one wall parallel to the horizontal plane and the other wall perpendicular to the horizontal plane, and the four adjusting members 22 correspond one-to-one with the four corners of the rectangular hole.
[0065] It is understandable that the vibrations during vehicle operation are mainly in the Z-axis and X-axis directions.
[0066] The four adjusting members 22 are positioned one-to-one with the four corners of the first through hole 241, meaning the four adjusting members 22 are located diagonally opposite the first through hole 241. Thus, when the vehicle generates Z-axis or X-axis vibration, the diagonally arranged adjusting members 22 can decompose the vibration force; that is, all four adjusting members 22 can absorb, store, and dampen Z-axis and X-axis vibrations. This avoids the limitation of the adjusting members 22 in damping, allowing them to dampen vibrations in multiple directions. Therefore, the arrangement of the adjusting members 22 is more consistent with the overall vehicle movement and adapts to various vehicle motion states.
[0067] Furthermore, by arranging the first plate 23 and the second plate 24 at intervals along the axis of the first through hole 241, the first plate 23 is located within the first through hole 241, meaning that the adjusting member 22 can be located outside the first through hole 241. This allows the movement of the adjusting member 22 to be unimpeded by the second plate 24, increasing the range of vibrations that the adjusting member 22 can buffer, thereby improving the adaptability of the rigid tube connection assembly 1.
[0068] Please see Figure 1In some embodiments, the second plate 24 is provided with a plurality of second through holes 242. In this way, during the process of the adjusting member 22 buffering vibration, the porous structure formed by the plurality of second through holes 242 can release vibration energy more quickly and reduce the vibration amplitude and number of vibrations 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 the same as that of the vehicle, making the structure more stable.
[0070] Please see 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 connector 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 provided on the first sub-plate 243.
[0072] The second sub-plate 244 is configured to connect to the vehicle. Specifically, the second sub-plate 244 is fastened to the vehicle body or frame by bolts.
[0073] For example, a plate is bent to form a connected first sub-plate 243 and second sub-plate 244. Alternatively, the independent first sub-plate 243 and second sub-plate 244 are welded together to form a second plate 24.
[0074] It is understood that the first plate 23 and the second plate 24 are set 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 the vehicle body or frame on which the second plate 24 is mounted and the axis of the pipe joint 21.
[0075] In this embodiment, the above-described configuration achieves the connection between the second plate 24 and the vehicle body or frame, as well as the connection between the second plate 24 and the adjusting member 22, while also making the structure of the second plate 24 simple and easy to manufacture.
[0076] Please see Figure 1 In some embodiments, a reinforcing rib 25 is provided between the first sub-plate 243 and the second sub-plate 244. This can improve the strength of the connection between the first sub-plate 243 and the second sub-plate 244, thereby improving the structural reliability of the rigid tube connection assembly 1.
[0077] In some embodiments, the adjusting member 22 is provided with a plurality of third through holes 223. Thus, during the process of the adjusting member 22 buffering vibration, the porous structure formed by the plurality of third through holes 223 can release vibration energy more quickly, reducing the vibration amplitude and number of vibrations 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 the same as that of the vehicle, making the structure more stable.
[0079] It is understandable that when the adjusting member 22 is an elastic member, providing a third through hole 223 on the adjusting member 22 should not reduce the durability of the elastic member; the third through hole 223 should be provided within the limits allowed by its strength modes. Therefore, the elastic member can be thickened, or only the part of the elastic member with the third through hole 223 can be locally thickened to improve the strength of the elastic member and meet the durability requirements of the elastic member.
[0080] Please see Figure 1 In some embodiments, the adjusting member 22 is a helical spring. This allows the adjusting member 22 to have good elastic deformation properties. Furthermore, the helical spring can withstand a large amount of cyclic load without easily fatigued, resulting in high reliability.
[0081] Please see Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the brake rigid tube assembly 3 provided in an exemplary embodiment of this disclosure. Figure 7 This is a schematic diagram of another brake rigid tube assembly 3 provided in an exemplary embodiment of this disclosure. Accordingly, embodiments of this application also provide a brake rigid tube assembly 3. The brake rigid tube assembly 3 includes a rigid tube 31 and the aforementioned rigid tube connection assembly 1. The rigid tube 31 includes a first sub-rigid tube 311 and a second sub-rigid tube 312. One end of the first sub-rigid tube 311 is connected to one end of the pipe connector 21. One end of the second sub-rigid tube 312 is connected to the other end of the pipe connector 21.
[0082] Specifically, one end of the first sub-hard pipe 311 is connected to one pipe interface 211 of the pipe connector 21. One end of the second sub-hard pipe 312 is connected to the other pipe interface 211 of the pipe connector 21.
[0083] In this embodiment, by employing the rigid pipe connection assembly 1 provided in some embodiments of this application, the adjustable dimensions of the pipe connector 21 relative to the vehicle body or frame can be improved. This facilitates compensation for processing and assembly errors of components such as the sub-rigid pipe and the rigid pipe connection assembly 1 through the elastic deformation of the adjusting member 22. This improves the smoothness of the connection between the sub-rigid pipe and the pipe connector 21, as well as the ease of operation of connecting the adjusting member 22 to the vehicle body or frame. Ultimately, it improves the stress state at the connection point between the sub-rigid pipe and the pipe connector 21, thereby enhancing the reliability of the connection between the sub-rigid pipe and the rigid pipe connection assembly 1.
[0084] Embodiments of this application also provide a vehicle including the aforementioned brake rigid pipe assembly 3. The end of the adjusting member 22 away from the pipe connector 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 employing the brake rigid tube assembly 3 provided in some embodiments of this application, the adjustable dimensions of the tube connector 21 relative to the vehicle body or frame can be improved. This facilitates compensation for machining and assembly errors of components such as the sub-rigid tube and the rigid tube connection assembly 1 through the elastic deformation of the adjusting member 22. This improves the smoothness of the connection between the sub-rigid tube and the tube connector 21, as well as the ease of operation of connecting the adjusting member 22 to the vehicle body or frame. Ultimately, it improves the stress state at the connection point between the sub-rigid tube and the tube connector 21, thereby enhancing vehicle reliability.
