Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicles, and more specifically, to a swing arm device with a cooling pipeline. In addition, the utility model also relates to a swing arm vehicle including the above swing arm device with a cooling pipeline. Background Art
[0002] At present, on some special vehicles or automobiles, a hub motor is used in the swing arm system. During the use of the hub motor, a large amount of heat is dissipated, and cooling water must be used for cooling. Due to structural design reasons, for the part of the cooling water path from the swing arm to the vehicle body, hoses are basically used, and the structure is as Figure 1 and Figure 2 shown. That is, the inlet and outlet of the cooling water pipe of the hub motor 02 (which is used to drive the tire 01 to rotate) are connected to the cooling water pipe (hose) 06 through a hard pipe 03 welded to the swing arm body 04. The cooling water pipe (hose) 06 is wound around the oil-gas spring 05. Among them, the oil-gas spring 05 can drive the swing arm body 04 to rotate around the swing arm shaft 07 through expansion and contraction. The cooling water pipe (hose) 06 is wound around the oil-gas spring 05 to ensure that when the oil-gas spring 05 expands and contracts, the cooling water pipe (hose) 06 has enough expansion space.
[0003] However, this solution has very obvious defects. Firstly, the cooling water pipe (hose) 06 moves up and down and follows the movement, and is prone to interference and friction with the vehicle body and the oil-gas spring 05, resulting in the rupture of the cooling water pipe (hose) 06. Secondly, for some vehicles with bulletproof requirements (such as military vehicles), the cooling water pipe (hose) 06 is exposed. In addition to the risk of being damaged by road stones and the like, the risk of being damaged by bullet shooting and causing the hub motor 02 to fail to work properly is extremely high.
[0004] In summary, how to solve the problems of the exposed cooling water pipe and its easy breakage is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model
[0005] In view of this, the purpose of the utility model is to provide a swing arm device with a cooling pipeline, which can solve the problems of the exposed cooling water pipe and its easy breakage.

[0035] The core of the present invention is to provide a swing arm device with a cooling pipeline, which can solve the problems of the cooling water pipe being exposed and easily damaged. Another core of the present invention is to provide a swing arm vehicle including the above swing arm device with a cooling pipeline.
[0036] Please refer to Figures 3 to 6 , Figure 3 which is the structural schematic diagram of the swing arm device with a cooling pipeline provided by the present invention; Figure 4 is Figure 3 the top view of Figure 5 is Figure 4 the partial enlarged view at A of Figure 6 and
[0037] This specific embodiment provides a swing arm device with a cooling pipeline, including:
[0038] A swing arm shaft 7, which is provided with an annular water outlet groove 72 and an annular water inlet groove 73 along the circumferential direction, and a water channel 75 is provided along the axial direction of the swing arm shaft 7. Both the annular water outlet groove 72 and the annular water inlet groove 73 are led to the vehicle body through the water channel 75;
[0039] The swing arm body 4 is rotatably arranged around the swing arm shaft 7. The swing arm body 4 is provided with a water outlet joint 41 communicating with the annular water outlet groove 72 and a water inlet joint 42 communicating with the annular water inlet groove 73.
[0040] The cooling water pipe 3 is arranged at the lower part of the swing arm body 4. The cooling water pipe 3 includes a water inlet hard pipe and a water outlet hard pipe. One end of the water inlet hard pipe is used to connect with the reserved water inlet of the hub motor 2, and the other end is connected with the water inlet joint 42. One end of the water outlet hard pipe is used to connect with the reserved water outlet of the hub motor 2, and the other end is connected with the water outlet joint 41.
[0041] It should be noted that a tire 1 is sleeved on the outer periphery of the hub motor 2 to drive the tire 1 to rotate. The oil-gas spring 5 can drive the swing arm body 4 to rotate around the swing arm shaft 7 through telescopic movement. The reserved water inlet on the hub motor 2 is communicated with the water inlet joint 42 through the water inlet hard pipe, and then with the annular water inlet groove 73. The reserved water outlet on the hub motor 2 is communicated with the water outlet joint 41 through the water outlet hard pipe, and then with the annular water outlet groove 72. Moreover, both the annular water inlet groove 73 and the annular water outlet groove 72 are communicated with the water channel 75 in the axial direction of the swing arm shaft 7 to realize the circulating flow of water between the vehicle body and the hub motor 2.
[0042] In actual operation, the shape, structure, size, material, etc. of the swing arm shaft 7, the swing arm body 4, and the cooling water pipe 3 can be determined according to the actual situation and actual needs.
[0043] When using the swing arm device with a cooling pipeline provided by the present utility model, water can enter from the reserved water inlet of the hub motor 2, pass through the water inlet hard pipe into the water inlet joint 42, then flow into the annular water inlet groove 73 and into the water channel 75, and then the water can enter the vehicle body. Subsequently, the water in the vehicle body can flow through the water channel 75 to the annular water outlet groove 72, then to the water outlet joint 41, and then the water can flow through the water outlet hard pipe and flow to the reserved water outlet of the hub motor 2 to realize the circulating flow of water between the vehicle body and the hub motor 2.
[0044] The cooling water pipe 3 of this device is arranged at the lower part of the swing arm body 4 and is a rigid pipe fitting, so the cooling water pipe 3 has no external leakage and is less likely to be damaged. The water inlets and outlets of the vehicle body are both communicated with the water channel 75 of the swing arm shaft 7. When the swing arm body 4 rotates around the swing arm shaft 7, it can drive the cooling water pipe 3 to rotate synchronously to realize the water flow between the vehicle body and the hub motor 2. This cooling water pipe 3 will not have telescopic movement, which helps to reduce the original probability of damage to the cooling hose and enhance the aesthetics of the vehicle.
[0045] In summary, the swing arm device with a cooling pipeline provided by the present utility model can solve the problems of the cooling water pipe being exposed and easily damaged.
[0046] In one embodiment, the inlet rigid pipe is connected to the inlet joint 42 through the hose 6, and the outlet rigid pipe is connected to the outlet joint 41 through the hose 6.
[0047] It should be noted that setting both the inlet rigid pipe and the outlet rigid pipe as rigid pipe fittings is beneficial to improving the service life of the inlet rigid pipe and the outlet rigid pipe. The inlet rigid pipe and the inlet joint 42, as well as the outlet rigid pipe and the outlet joint 41, are both connected through the hose 6, which can ensure the proper connection between components.
[0048] In one embodiment, the swing arm body 4 is sleeved on the swing arm shaft 7 through the bushing 43, and the bushing 43 is provided with through holes communicating with the outlet joint 41 and the inlet joint 42. By providing the bushing 43 between the swing arm body 4 and the swing arm shaft 7, it is beneficial to improve the rotation effect of the swing arm body 4 rotating around the swing arm shaft 7, reduce the wear between the swing arm body 4 and the swing arm shaft 7, and improve the service life of the swing arm body 4 and the swing arm shaft 7.
[0049] In one embodiment, both the outlet joint 41 and the inlet joint 42 are welded in the through holes. That is to say, the outlet joint 41 and the inlet joint 42 can be welded on the bushing 43 of the swing arm body 4 to ensure the fixing effect of the device and reduce the assembly steps.
[0050] In one embodiment, there are multiple first sealing rings 71, multiple second sealing rings 74, and multiple third sealing rings 76 provided on the swing arm shaft 7. The annular water outlet groove 72 is located above the annular water inlet groove 73. The first sealing ring 71 is located above the annular water outlet groove 72, the second sealing ring 74 is located below the annular water inlet groove 73, and the third sealing ring 76 is located between the annular water outlet groove 72 and the annular water inlet groove 73. The annular water outlet groove 72 and the annular water inlet groove 73 lead the water flow to the end of the swing arm shaft 7 through the water channel 75, and then enter the vehicle body. By providing multiple first sealing rings 71, multiple second sealing rings 74, and multiple third sealing rings 76 on the swing arm shaft 7, it can effectively prevent the leakage of cooling water.
[0051] In one embodiment, the first sealing ring 71, the second sealing ring 74, and the third sealing ring 76 all include O-rings. That is to say, the types of the first sealing ring 71, the second sealing ring 74, and the third sealing ring 76 are not limited to O-rings, and can also be other types of sealing rings.
[0052] In one embodiment, the inlet rigid pipe is welded to the lower part of the swing arm body 4 and extends into the swing arm body 4 to be connected to the inlet joint 42. The outlet rigid pipe is welded to the lower part of the swing arm body 4 and extends into the swing arm body 4 to be connected to the outlet joint 41, so as to ensure the assembly effect of the cooling water pipe 3 and the swing arm body 4 and avoid the cooling water pipe 3 being easily detached when the swing arm body 4 rotates.
[0053] It should be noted that since the cooling water pipe 3 is arranged at the lower part of the swing arm body 4 and the hose 6 is arranged inside the swing arm body 4, when the swing arm body 4 rotates around the swing arm shaft 7, the hose 6 has no telescopic movement, effectively avoiding the possibility of the hose 6 being damaged by external forces and reducing the breakage probability of the hose 6. Moreover, since the hose 6 no longer telescopes, that is, the length of the hose 6 is fixed, it is beneficial to enhance the aesthetics of the vehicle.
