[0034] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0035] A fixing assembly 1 of a power steering system according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 4As shown, the fixing assembly 1 according to the embodiment of the utility model includes a first bracket 100 , a second bracket 200 and an elastic vibration damping member 300 .

[0037] The first bracket 100 is suitable for being connected to a wire harness and / or a pipeline, the second bracket 200 is suitable for being fixed to a vehicle frame 700 , and the elastic vibration damping member 300 is disposed between the first bracket 100 and the second bracket 200 .

[0038] The elastic vibration damping member 300 includes a first connecting portion 310, a second connecting portion 320 and an elastic portion 330, the first connecting portion 310 is connected to the first bracket 100, the second connecting portion 320 is connected to the second bracket 200, the first connecting portion 310 and the second connecting portion 320 are connected to opposite sides of the elastic portion 330 in the first direction, and the elastic portion 330 is configured with at least one vibration damping hole 331, and the vibration damping hole 331 passes through the opposite sides of the elastic portion 330 in the second direction.

[0039] Among them, the direction indicated by arrow B in the figure is the first direction, the direction indicated by arrow C is the second direction, and the direction indicated by arrow D is the third direction.

[0040] The first bracket 100 is connected to the wiring harness and / or pipeline, which means that the first bracket 100 can be connected to the wiring harness to fix the wiring harness, or the first bracket 100 can be connected to the pipeline to fix the pipeline, or the first bracket 100 can be connected to the wiring harness and the pipeline at the same time to fix the wiring harness and the pipeline at the same time. The fixing component 1 can be used to fix the oil supply pipeline 610 and the oil return pipeline 620 of the power steering system, or the fixing component 1 can also be used to fix the air conditioning pipeline of the air conditioning system. Of course, the fixing component 1 can also be used to fix the pipelines of other components or the wiring harness for electrical connection.

[0041] Among them, the first direction can be the height direction of the elastic part 330, which is also the up and down direction of the frame 700 in the figure in this embodiment, and the second direction can be the width direction of the elastic part 330, which is also the front and back direction of the frame 700 in the figure in this embodiment. In this way, the vibration damping hole 331 can be avoided from position interference with the first connecting part 310 and the second connecting part 320, and the layout is more reasonable.

[0042] According to the fixing assembly of the embodiment of the utility model, the first bracket 100 is connected to the wire harness and / or pipeline, the second bracket 200 is fixed to the frame 700, and the elastic vibration damping member 300 is respectively connected to the first bracket 100 and the second bracket 200. In this way, the first bracket 100 and the second bracket 200 can be connected together, and then the wire harness and / or pipeline can be connected to the frame 700, so that the wire harness and / or pipeline can be fixed by the frame 700 to prevent the wire harness and / or pipeline from shaking.

[0043] In addition, the elastic vibration damper 300 is arranged between the first bracket 100 and the second bracket 200, and the elastic vibration damper 300 includes a first connecting portion 310, a second connecting portion 320 and an elastic portion 330. The first connecting portion 310 is connected to the first bracket 100, and the second connecting portion 320 is connected to the second bracket 200. In this way, the elastic vibration damper 300 can be used to absorb vibrations of the first bracket 100 and the second bracket 200. When the first bracket 100 and the second bracket 200 are relatively displaced, the first bracket 100 and the second bracket 200 can squeeze the elastic vibration damper 300, so that the elastic vibration damper 300 can be used for buffering. In this way, when the vehicle bumps violently and the wiring harness and / or pipeline fixed by the fixing assembly 1 tends to move relative to the frame 700, the elastic vibration damper 300 can be used for buffering, thereby avoiding damage to the connecting structure between the first bracket 100 and the second bracket 200, so that the connection between the first bracket 100 and the second bracket 200 is more reliable, and the connection between the wiring harness and / or pipeline and the frame 700 is more reliable.

[0044] Moreover, the first connecting portion 310 and the second connecting portion 320 are connected to opposite sides of the elastic portion 330 in the first direction, so that the first bracket 100 and the second bracket 200 can be connected to opposite sides of the elastic portion 330. When the first bracket 100 and the second bracket 200 are relatively displaced, the first bracket 100 and the second bracket 200 can squeeze the elastic portion 330, so that the elastic portion 330 can be used for buffering to fully absorb vibration, and the elastic vibration damping member 300 has a better vibration damping effect.

[0045] In addition, the elastic portion 330 is configured with at least one vibration-reducing hole 331 , and the vibration-reducing hole 331 penetrates through two opposite sides of the elastic portion 330 in the second direction.

[0046] For example, the elastic part 330 can be constructed with a vibration-damping hole 331, which not only helps the vibration-damping hole 331 to reduce the weight of the elastic part 330 and reduce the material used, but also helps the vibration-damping hole 331 to reduce the stiffness of the elastic part 330. The hardness of the elastic part 330 can be greatly reduced to make the deformation effect of the elastic part 330 better, and then the elastic part 330 can be used to buffer the relative displacement of the first bracket 100 and the second bracket 200 to a greater extent, and the elastic part 330 can be used to better absorb vibration and achieve a better vibration reduction effect.

[0047] Alternatively, the elastic part 330 may also be constructed with a plurality of vibration-damping holes 331, and the plurality of vibration-damping holes 331 are arranged at intervals, that is, the elastic part 330 is constructed with a plurality of vibration-damping holes 331 with smaller cross-sectional areas, and adjacent vibration-damping holes 331 are not connected. In this way, while reducing the stiffness of the elastic part 330, excessive deformation of the elastic part 330 can be avoided, and the connection stability between the first bracket 100 and the second bracket 200 through the elastic vibration-damping component 300 is higher.

[0048] In this way, the fixing assembly 1 according to the embodiment of the utility model can better absorb vibration for buffering, effectively avoid damage to the connection structure between the first bracket 100 and the second bracket 200, and the connection reliability is higher.

[0049] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the two opposite side surfaces of the elastic portion 330 in the third direction are constructed as arc-shaped surfaces protruding outward, and the arc-shaped surfaces are arranged opposite to the vibration-damping hole 331 .

[0050] The third direction may be the length direction of the elastic portion 330 , which is also the left-right direction of the vehicle frame 700 in the figure in this embodiment.

[0051] By constructing outwardly protruding arc surfaces on the two opposite sides of the elastic part 330 in the third direction, when the first bracket 100 and the second bracket 200 squeeze the elastic part 330 to deform the elastic part 330, stress concentration in the elastic part 330 can be avoided, thereby avoiding damage to the elastic part 330, and the service life of the elastic part 330 can be extended.

[0052] In addition, the arc surface and the vibration damping hole 331 are arranged relative to each other, which means that in the first direction, the arc surface can correspond to the height of the vibration damping hole 331, so that the thickness of the side wall of the vibration damping hole 331 can be ensured to be thicker, and the structural strength of the elastic part 330 is further improved. When the elastic part 330 is squeezed and deformed, the side wall of the vibration damping hole 331 is not easily damaged, so that the service life of the elastic part 330 can be longer.

[0053] In some specific embodiments of the present invention, the vibration-damping hole 331 is constructed as an elliptical hole and / or an elongated hole. In this way, the structure of the vibration-damping hole 331 can be simpler and easier to process, and the inner side wall of the vibration-damping hole 331 can also be an arc-shaped surface. When the elastic part 330 is squeezed and deformed, stress concentration is less likely to occur, and the elastic part 330 is more effectively prevented from being squeezed and damaged.

[0054] In some specific embodiments of the present invention, Figure 4 As shown, the length of the vibration-damping hole 331 in the third direction is greater than the height of the vibration-damping hole 331 in the first direction.

[0055] It is understandable that when the oil supply pipeline 610 or the oil return pipeline 620 is relatively displaced with the frame 700, the first bracket 100 and the second bracket 200 will squeeze the elastic part 330 along the first direction. By setting the height of the vibration-damping hole 331 in the first direction to be smaller, it is possible to avoid excessive deformation of the elastic part 330, thereby limiting the relative displacement of the first bracket 100 and the second bracket 200, and avoiding excessive shaking of the oil supply pipeline 610 or the oil return pipeline 620 relative to the frame 700.

[0056] Furthermore, by setting the length dimension of the vibration-damping hole 331 in the third direction to be larger, it is possible to ensure that the elastic portion 330 has a better deformation effect, so that the elastic portion 330 can better absorb vibration and achieve a better vibration-damping effect.

[0057] In some specific embodiments of the present invention, Figure 3 As shown, the first bracket 100 includes a first plate body 110 and a second plate body 120 .

[0058] The second plate 120 is disposed on a side of the first plate 110 facing away from the elastic portion 330 and is stacked with the first plate 110 . The first connecting portion 310 passes through the middle of the first plate 110 and the middle of the second plate 120 to fix the first plate 110 and the second plate 120 .

[0059] In addition, first arc-shaped portions 111 are constructed at both ends of the first plate body 110, and second arc-shaped portions 121 are constructed at both ends of the second plate body 120. The second arc-shaped portion 121 and the first arc-shaped portion 111 are arranged opposite to each other and define a clamping hole 130. The clamping hole 130 is suitable for the wire harness and / or pipeline to pass through so as to clamp the wire harness and / or pipeline.

[0060] That is to say, the first bracket 100 can be configured with a plurality of clamping holes 130, for example, each of the two ends of the first bracket 100 can have a clamping hole 130, so that the first bracket 100 can be connected to a plurality of wire harnesses and / or pipelines at the same time, and then the plurality of wire harnesses and / or pipelines can be fixed to the vehicle frame by using the fixing assembly 1. In addition, by connecting the first connecting portion 310 to the middle of the first plate body 110 and the middle of the second plate body 120, that is, the first connecting portion 310 is connected to the middle of the first bracket 100, the clamping holes 130 at the two ends of the first bracket 100 can be arranged on both sides of the first connecting portion 310, and after the first bracket 100 is connected to the wire harness and / or pipeline, the weight distribution is more uniform, which is conducive to improving the stability of the fixing assembly 1 in fixing the wire harness and / or pipeline.

[0061] In addition, in this arrangement, the first plate body 110 and the second plate body 120 can be separately arranged and connected through the first connecting portion 310, and the structure of the first bracket 100 can be simpler and easier to process. Moreover, the first arc portion 111 and the second arc portion 121 can move relative to each other, and the clamping hole 130 defined by the first arc portion 111 and the second arc portion 121 is a non-closed hole, that is, the diameter of the clamping hole 130 can be adaptively adjusted according to the diameter of the pipeline or the wire harness.

[0062] It is understandable that when the liquid in the pipeline flows, for example, in the power steering system 2, when the oil in the oil supply pipeline 610 or the oil return pipeline 620 flows rapidly, the diameter of the pipeline will change. In the embodiment of the utility model, not only can the elastic portion 330 be used to absorb the impact of the change in the diameter of the pipeline on the fixing component 1, but also the first arc portion 111 and the second arc portion 121 can be squeezed and expanded outward after the diameter of the pipeline increases to adapt to the change in the diameter of the oil supply pipeline 610 or the oil return pipeline 620, so that the fixation is more reliable.

[0063] In some specific embodiments of the present invention, Figure 3 As shown, the second bracket 200 includes a first bending section 210 and a second bending section 220 .

[0064] The first bending section 210 is suitable for being connected to the side of the frame, the second bending section 220 is connected to the first bending section 210 and is bent relative to the first bending section 210, and the second bending section 220 is suitable for extending to the upper side of the frame 710 and being spaced apart from the frame 710 to facilitate the connection between the second connecting portion 320 and the second bending section 220.

[0065] Furthermore, by spacing the second bending section 220 and the frame 700, the second bending section 220 will not interfere with the frame 700. Meanwhile, when the second connecting portion 320 passes through the second bending section 220 and connects with the second bracket 200, the second connecting portion 320 is not likely to interfere with the frame 700, thereby facilitating assembly.

[0066] Furthermore, if Figure 3 As shown, the second bending section 220 can be constructed with a sliding hole 221. For example, the sliding hole 221 can extend along the length direction of the second bending section 220, and the second connecting part 320 can slide along the sliding hole 221. In this way, the sliding hole 221 can be used to absorb the assembly error between the elastic vibration damping member 300 and the second bracket 200, which is convenient for assembly. After the assembly is in place, the second connecting part 320 can be tightened with a nut to prevent the elastic vibration damping member 300 and the second bracket 200 from relative displacement, and the connection is more reliable.

[0067] Furthermore, it is understandable that when the elastic portion 330 is deformed, it will also drive the second connection portion 320 to move, that is, the second connection portion 320 will tend to move relative to the second bracket 200. By setting the sliding hole 221, when the elastic portion 330 is deformed to a large extent, that is, when the second connection portion 320 is subjected to a large force, the second connection portion 320 can be allowed to move slightly along the sliding hole 221, so as to avoid damage to the connection structure between the second connection portion 320 and the second bracket 200, and the structural setting is more reasonable.

[0068] In some specific embodiments of the present invention, the first connection portion 310 and the second connection portion 320 both include a connection plate 311 and a threaded rod 312 .

[0069] The elastic portion 330 is connected to one side of the connecting plate 311 in the thickness direction, and the other side of the connecting plate 311 in the thickness direction is constructed as a plane and abuts against the first bracket 100 or the second bracket 200. The threaded rod 312 is arranged on the other side of the connecting plate 311 in the thickness direction, and the threaded rod 312 is connected to the first bracket 100 and / or the second bracket 200.

[0070] By constructing the other side of the connecting plate 311 in the thickness direction as a plane, that is, the side of the connecting plate 311 facing the first bracket 100 or the second bracket 200 is constructed as a plane, the contact area between the elastic vibration damping member 300 and the first bracket 100 or the second bracket 200 can be increased, the force on the elastic part 330 can be more uniform, and the connection stability between the elastic vibration damping member 300 and the first bracket 100 and the second bracket 200 is higher, thereby improving the connection reliability of the fixing component 1, thereby improving the connection stability between the wiring harness and / or pipeline and the frame 700.

[0071] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the central axis of the threaded rod 312 of the first connecting part 310 and the central axis of the threaded rod 312 of the second connecting part 320 coincide with each other. Thus, when the first bracket 100 and the second bracket 200 squeeze the elastic part 330, the squeezing force of the first connecting part 310 on the elastic part 330 and the squeezing force of the second connecting part 320 on the elastic part 330 can be in opposite directions and be collinear, thereby avoiding the squeezing force of the first connecting part 310 on the elastic part 330 and the squeezing force of the second connecting part 320 on the elastic part 330 from being staggered, so as to better utilize the elastic part 330 to absorb the squeezing force of the first bracket 100 and the second bracket 200 on the elastic part 330, and the buffering and vibration reduction effect of the elastic vibration damping member 300 is better.

[0072] A power steering system 2 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0073] like Figure 1As shown, the power steering system 2 includes a steering gear 400, a steering pump 500, a steering oil tank 600 and a fixing assembly 1 according to the above embodiment of the present utility model.

[0074] The steering oil tank 600 has an oil outlet and an oil return port, the oil outlet is connected to the steering pump 500, the steering pump 500 is connected to the steering gear 400 through an oil supply pipeline 610, and the steering gear 400 is connected to the oil return port through an oil return pipeline 620, and the oil supply pipeline 610 and / or the oil return pipeline 620 are suitable for being connected to the vehicle frame 700 through the fixing assembly 1. The oil supply pipeline 610 can be a steel pipe, and the oil return pipeline 620 can be a rubber hose.

[0075] Thus, the steering oil tank 600, the steering pump 500, the oil supply pipeline 610, the steering gear 400 and the oil return pipeline 620 can form a complete oil circuit, and the oil can flow from the oil outlet of the steering oil tank 600 to the steering pump 500, and then flow to the steering gear 400 through the oil supply pipeline 610, and finally the oil flows out of the steering gear 400 and flows back to the steering oil tank 600 through the oil return pipeline 620 and the oil return port.

[0076] Furthermore, by absorbing vibrations through the elastic damping member 300 of the fixing assembly 1, the vibrations transmitted from the vehicle frame 700 to the oil supply line 610 and the oil return line 620 can be reduced, thereby preventing the oil supply line 610 and the oil return line 620 from vibrating too much, and reducing vibration noise, thereby effectively preventing damage to the connection between the oil supply line 610 and the oil return line 620 and other components. For example, damage to the connection between the oil supply line 610 and the oil return line 620 and the steering gear 400 or the steering oil tank 600 can be prevented, thereby preventing oil leakage from the power steering system 2.

[0077] According to the power steering system 2 of the embodiment of the utility model, by utilizing the fixing component 1 according to the above-mentioned embodiment of the utility model, the fixing component 1 can absorb vibration, effectively avoiding damage to the connection structure between the first bracket 100 and the second bracket 200, the connection reliability is higher and oil leakage of the power steering system 2 can be avoided.
