Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorbing installation structure for a motorcycle. Background Art

[0002] The motorcycle shock absorber is mainly composed of a piston rod and a spring mounted on the outer end of the piston rod. Through repeated compression and stretching of the spring, it can absorb and disperse the vibration energy of the vehicle body.

[0003] In the prior art, most motorcycle rear shock absorbers are directly installed between the wheel and the frame. Although this can meet the basic daily shock absorption needs, for some riders who often travel on bumpy and rugged roads, the existing motorcycle rear shock absorber installation method cannot bring them a good riding experience, especially for off-road motorcycles that need to travel in complex environments. Utility Model Content

[0004] In view of this, the utility model provides a motorcycle shock-absorbing mounting structure, aiming to improve the vibration reduction effect of the motorcycle shock absorber and ensure the riding experience of the rider.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A shock-absorbing mounting structure for a motorcycle comprises a vehicle body, wherein the vehicle body is mounted with a rear wheel via a first flat fork, and is characterized in that a shock absorber body and a supporting component are arranged in a middle area of ​​the vehicle body, wherein the supporting component is circumferentially provided with a first transfer interface, a second transfer interface and a third transfer interface, one end of the shock absorber body is hinged to the vehicle body, and the other end is hinged to the first transfer interface, the second transfer interface is hinged with a second flat fork, the third transfer interface is hinged to the vehicle body, one end of the second flat fork away from the supporting component is rotatably connected to the rear end of the first flat fork, and the front end of the first flat fork is hinged to the vehicle body.

[0007] By adopting the above structure and designing the supporting component and the second flat fork, the transmission stroke of the pressure applied to the motorcycle by the outside world is made longer. Compared with directly installing the shock-absorbing damper, the compression stroke between the lower side of the vehicle seat cushion and the upper end of the rear wheel can be significantly improved, thereby making the shock-absorbing effect of the motorcycle more obvious.

[0008] As a preferred embodiment, the first adapter, the second adapter and the third adapter are distributed in a triangular shape. With the above structure, the support component is subjected to a more uniform force.

[0009] As a preferred embodiment, the first flat fork is provided with an assembly seat at a position corresponding to the rear wheel, the upper part of the assembly seat is provided with a protrusion extending forward, and the rear end of the second flat fork is hinged to the protrusion. With the above structure, the second flat fork can be installed.

[0010] Preferably, the support member, the first flat fork, the second flat fork and the vehicle body form a four-bar linkage. The above structure can increase the transmission distance of the vibration energy received by the motorcycle, thereby increasing the compression stroke between the lower side of the vehicle body seat cushion and the upper end of the rear wheel, thereby improving the shock absorption effect of the motorcycle.

[0011] Preferably, the support component includes two parallel side support plates and transition columns integrally formed on the two side support plates, and the side support plates are provided with mounting holes at positions corresponding to the respective transfer ports. The above structure makes the support component more solid.

[0012] Preferably, the transition column has a weight-reducing hole inside that runs through the thickness direction of the support component. With the above structure, the support component can ensure a firm structure while making it lighter.

[0013] Preferably, the assembly seat is provided with a movable groove, and the axle of the rear wheel is mounted in the movable groove in a forward and backward adjustable manner. The above structure can not only meet the requirements of the rear wheel rotation installation, but also change the maximum adjustment stroke of the shock-absorbing mounting structure by adjusting the position of the rear wheel.

[0014] Preferably, the shock absorber body includes a buffer piston connected between the vehicle body and the supporting component, and a shock absorbing spring sleeved on the outside of the buffer piston. With the above structure, the shock absorber body can continuously expand and contract to disperse the vibration energy of the vehicle body, thereby playing a role in shock absorption.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The motorcycle shock-absorbing mounting structure provided by the utility model is adopted, through the design of the supporting component and the second flat fork, so that the overall shock-absorbing structure is composed of a four-bar linkage and a unilaterally retractable triangle. When the rear wheel suddenly falls and is subjected to force, the pressure exerted on the motorcycle can be transmitted to the shock absorber by the four-bar linkage. Compared with directly installing the shock-absorbing damper, the compression stroke between the lower side of the vehicle body seat cushion and the upper end of the rear wheel can be significantly improved, thereby making the shock-absorbing effect of the motorcycle more obvious.

[0023] The utility model is further described below in conjunction with embodiments and drawings.

[0024] The directions such as “front”, “rear”, “up” and “down” mentioned in this embodiment are directions when the motorcycle is actually in use.

[0025] The motorcycle shock-absorbing installation structure provided in this embodiment is very suitable for Figure 1 The electric off-road motorcycle shown.

[0026] like Figures 1 to 5 As shown, a shock-absorbing mounting structure for a motorcycle includes a vehicle body 1, a rear wheel 2 is mounted on the vehicle body 1 through a first flat fork 4, a shock absorber body 3 and a support component 5 are mounted in the middle area of ​​the vehicle body 1, wherein the support component 5 is circumferentially provided with a first transfer port 5a, a second transfer port 5b and a third transfer port 5c. In this embodiment, one end of the shock absorber body 3 is hinged on the vehicle body 1, and the other end is hinged on the first transfer port 5a, the second transfer port 5b is hinged with a second flat fork 6, the third transfer port 5c is hinged to the vehicle body 1, one end of the second flat fork 6 away from the support component 5 is rotatably connected to the rear end of the first flat fork 4, and the front end of the first flat fork 4 is hinged to the vehicle body 1.

[0027] With such a design, through the support component 5 hinged on the vehicle body 1 and the second fork 6 hinged to the first fork 4, when the motorcycle is subjected to vibration, the pressure can be transmitted to the support component 5 through the second fork 6, and then transmitted to the shock absorber body 3 by the support component 5, which makes the pressure transmission path of the motorcycle longer, and can significantly improve the compression stroke between the lower side of the seat cushion of the vehicle body 1 and the upper end of the rear wheel 2, so that the shock absorption effect of the motorcycle is more obvious.

[0028] like Figure 6 As shown, the shock absorber body 3 is composed of a buffer piston 3a and a shock absorbing spring 3b mounted on the outside of the buffer piston 3a. When the motorcycle is vibrated, the buffer piston 3a and the shock absorbing spring 3 are forced to contract. During the contraction process, the shock absorber body 3 can absorb the pressure, thereby playing a role in reducing shock on the motorcycle.

[0029] In this embodiment, the first transfer interface 5a, the second transfer interface 5b and the third transfer interface 5c are distributed in a triangle. Figure 3This enables the pressure transmitted to the supporting component 5 to be dispersed more evenly when the motorcycle is subjected to vibration.

[0030] Further, such as Figure 4 As shown, the support component 5 includes two parallel side support plates 5d and transition columns 5e integrally formed on the two side support plates 5d. The side support plates 5d are provided with mounting holes at positions corresponding to the respective transfer ports, and the transition columns 5e are provided with weight-reducing holes 5f running through the thickness direction of the support component 5. Such a design ensures that the support component 5 is structurally firm while also making it lighter.

[0031] like Figure 5 As shown, an assembly seat 4a is provided at a position of the first flat fork 4 corresponding to the rear wheel 2, and a protrusion 4a1 extending forward is formed on the upper portion of the assembly seat 4a, and the rear end of the second flat fork 6 is hinged on the protrusion a1. The assembly seat 4a also has laterally distributed movable grooves 4a2, and the axle ends of the rear wheel 2 are rotatably supported in the corresponding two movable grooves 4a2. By moving the position of the rear wheel 2 in the movable groove 4a2 forward and backward, the lateral distance between the rear wheel 2 and the vehicle body 1 can be adjusted, and then the maximum shock absorbing stroke of the shock absorbing structure can be adjusted.

[0032] like Figure 2 As shown, a four-bar linkage is formed between the vehicle body 1, the first flat fork 4, the second flat fork 6 and the support component 5. Since the vehicle body 1, the first flat fork 4, the second flat fork 6 and the support component 5 are hinged to each other, when the motorcycle is subjected to bumpy pressure during driving, the pressure can be transmitted to the second flat fork 6 through the first flat fork 4, then transmitted to the support component 5 by the second flat fork 6, and finally transmitted to the shock absorber body 3 by the support component 5. The four-bar linkage increases the transmission path of bumpy pressure and plays a certain weakening role.

[0033] In this embodiment, a four-bar linkage is formed between the vehicle body 1, the first flat fork 4, the second flat fork 6 and the support component 5, and a triangular structure is formed between the support component 5, the shock absorber body 3 and the vehicle body 1. The two sets of mechanisms share the support component 5. Since the three points constituting the triangular structure are all rotationally connected, it is ensured that when the shock absorber body 3 is telescopically deformed, it can drive the support component 5 to rotate, thereby ensuring that the four-bar linkage can deform and move, thereby achieving a more excellent shock absorption effect.

[0034] Based on the above motorcycle shock absorption installation structure, combined with Figures 1 to 3The shock absorption process in actual use is as follows: when the motorcycle is bumpy and the rear wheel 2 is forced to fall to the ground from a high place, the vehicle body 1 and the rear wheel 2 will be subjected to upward vibration energy, and the vibration energy will force the first flat fork 4 to hinge and rotate upward, and drive the second flat fork 6 to move toward the shock absorber body 3. The movement of the second flat fork 6 can force the support component 5 to rotate toward the shock absorber body 3 with the third adapter 5c as the center of the circle. While the support component 5 rotates, it can transfer the vibration energy to the shock absorber body 3. The vibration energy forces the buffer piston 3a and the shock absorbing spring 3b to compress. The buffer piston 3a and the shock absorbing spring 3b absorb and dissipate energy during the compression process, and finally achieve the purpose of shock absorption. Compared with directly installing the shock absorbing damper, this structure can significantly increase the compression stroke between the lower side of the vehicle seat cushion and the upper end of the rear wheel, which also makes the shock absorption effect more obvious and can bring a better riding experience to the rider.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
