Description

Technical Field

[0001] This utility model relates to a scooter, and more particularly to a shock-absorbing scooter. Background Technology

[0002] Scooters are lightweight, flexible personal transportation and entertainment devices that are popular among people of all ages. In order to improve the comfort of users when using scooters, shock absorption devices are usually installed on both the front and rear wheels, so that the scooter is more stable when going over uneven roads.

[0003] However, the shock absorption devices used in current scooters are usually spring shock absorbers or shock absorbers composed of springs and hydraulic dampers. Whether it is a spring shock absorber or a shock absorber composed of springs and hydraulic dampers, it requires a buffer stroke during operation. Therefore, the structure of both types of shock absorbers is relatively large. As a result, sufficient installation space is required when installing spring shock absorbers or shock absorbers composed of springs and hydraulic dampers. This means that the scooter body must be made larger during manufacturing. Making the scooter body larger not only increases the weight of the scooter but also increases the space occupied by the scooter. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a shock-absorbing scooter that can ensure the installation of shock-absorbing devices without increasing the size of the vehicle body.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a shock-absorbing scooter, comprising a scooter body composed of a front frame, a rear frame, and a support frame. The front and rear ends of the support frame are respectively connected to the front and rear frames. A front wheel frame is provided on the front frame, and a rear wheel frame is provided on the rear frame. The rear frame includes a frame body, which is connected to the rear end of the support frame. An installation cavity is formed in the frame body, and a plurality of screw holes communicating with the interior of the installation cavity are formed on the outer wall of the installation cavity. A sleeve is installed in the installation cavity. The outer wall of the sleeve has positioning holes with the same number as the screw holes. When the sleeve is located in the installation cavity, the positioning holes are aligned with the screw holes. A bolt is provided in each screw hole, and the bottom of the bolt passes through the screw hole and is inserted into the positioning hole. A rubber body is fixedly installed in the sleeve. A connecting shaft is fixedly provided at the center of the rubber body, and both ends of the connecting shaft pass through the rubber body and are connected to the rear wheel frame.

[0006] A further preferred embodiment of this utility model is as follows: an end cap is provided at each of the left and right ends of the mounting cavity, and each end cap is provided with a through hole for the connecting shaft to pass through. The end cap is detachably connected to the frame.

[0007] A further preferred embodiment of this utility model is: a plurality of connecting rods fixedly connected to the rubber body are evenly arranged on the connecting shaft, and all the connecting rods are located in the rubber body.

[0008] A further preferred embodiment of this utility model is as follows: a polygonal connecting post is provided at each of the left and right ends of the connecting shaft, a connecting hole matching the connecting post is provided on the rear wheel frame, and a stud is provided on the outer side wall of each connecting post, and a nut for tightening the rear wheel frame is screwed onto the stud.

[0009] A further preferred embodiment of this utility model is as follows: a pressure block is sleeved on the connecting shaft inside the end cap, and the two sides of the pressure block abut against the inner wall of the end cap and the side wall of the rubber body, respectively.

[0010] A further preferred embodiment of this utility model is: a housing is detachably provided on the outer wall of the rear wheel frame, and the nut and stud are both located in the housing.

[0011] Compared with the prior art, the advantages of this utility model are that by combining the sleeve, rubber body and connecting shaft, a torsional rubber shock absorber is formed, which can absorb the vibration generated by the rear wheel. Since the sleeve, rubber body and connecting shaft are all located in the mounting cavity of the frame, the space occupied by the vehicle body when installing the shock absorber is reduced. Therefore, the vehicle body does not need to be made larger when manufacturing the scooter. This not only reduces the weight of the scooter but also reduces the space occupied by the scooter.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the structure of a shock-absorbing scooter, as follows:

[0026] like Figures 1-9 As shown, a shock-absorbing scooter includes a scooter body composed of a front frame 1, a rear frame 3, and a support frame 2. The front and rear ends of the support frame 2 are connected to the front frame 1 and the rear frame 3, respectively. A front wheel frame 4 is provided on the front frame 1, a rear wheel frame 5 is provided on the rear frame 3, a front wheel 6 is provided in the front wheel frame 4, and a rear wheel 7 is provided in the rear wheel frame 5.

[0027] The rear frame 3 includes a frame body connected to the rear end of the support frame 2. A mounting cavity 31 is formed within the frame body, and multiple screw holes 11 communicating with the interior of the mounting cavity 31 are formed on its outer wall. A sleeve 14 is placed within the mounting cavity 31, and positioning holes 141, the same number as the screw holes 11, are formed on the outer wall of the sleeve 14. When the sleeve 14 is in the mounting cavity 31, the positioning holes 141 align with the screw holes 11. A bolt 12 is placed in each screw hole 11, and the bottom of the bolt 12 can pass through the screw hole 11 and be inserted into the positioning hole 141. This allows the sleeve 14 to be fixed in the mounting cavity 31. To remove the sleeve 14 from the mounting cavity 31, the bolt 12 is simply removed from the screw hole 11, facilitating the assembly and disassembly of the mounting sleeve. Finally, the sleeve... A rubber body 15 is fixedly installed in the sleeve 14, and a connecting shaft 16 is fixedly installed at the center of the rubber body 15. Both ends of the connecting shaft 16 extend out of the rubber body 15 and connect to the rear wheel frame 5. In this way, the combination of the sleeve 14, the rubber body 15 and the connecting shaft 16 forms a torsional rubber shock absorber, which can absorb the vibration generated by the rear wheel 7. Since the sleeve 14, the rubber body 15 and the connecting shaft 16 are all located in the mounting cavity 31 of the frame, the space occupied by the vehicle body when installing the shock absorber is reduced. Therefore, the vehicle body does not need to be made larger during the manufacturing of the scooter. This allows the installation of the shock absorber to be guaranteed without increasing the size of the vehicle body, thereby reducing the weight of the scooter and reducing the space occupied by the scooter.

[0028] Furthermore, in order to ensure the reliability of the sleeve 14 and the rubber body 15 in the mounting cavity 31, an end cap 8 is provided at each of the left and right ends of the mounting cavity 31, and a through hole 81 for the connecting shaft 16 to pass through is provided on the end cap 8. In order to facilitate the disassembly and assembly of the end cap 8, the end cap 8 is detachably connected to the frame by bolts 12.

[0029] Furthermore, in order to improve the pressing effect of the end cap 8 on the rubber body 15, a pressure block 13 is fitted on the connecting shaft 16 inside the end cap 8, and the two sides of the pressure block 13 abut against the inner wall of the end cap 8 and the side wall of the rubber body 15, respectively.

[0030] Furthermore, in order to improve the firmness of the connection between the connecting shaft 16 and the rubber body 15, multiple connecting rods 17 that are fixedly connected to the rubber body 15 are evenly arranged on the connecting shaft 16, and the connecting rods 17 are all located in the rubber body 15. At the same time, the connecting rods 17 and the connecting shaft 16 are integrally formed.

[0031] Furthermore, to ensure the reliability of the rear wheel frame 5 in transmitting torque to the connecting shaft 16, a polygonal connecting post 9 is provided at each of the left and right ends of the connecting shaft 16. At the same time, a connecting hole matching the connecting post 9 is provided on the rear wheel frame 5. In this way, the rear wheel frame 5 is sleeved with the connecting post 9 through the connecting hole. In order to ensure the firmness of the rear wheel frame 5 when it is on the connecting post 9, a stud 10 is provided on the outer wall of the connecting post 9, and a nut 18 for tightening the rear wheel frame 5 is screwed on the stud 10. Finally, a mudguard 191 and a support frame assembly 19 are provided on the rear wheel frame 5.

[0032] Furthermore, in order to improve the service life of stud 10 and nut 18, a housing 51 is detachably provided on the outer wall of the rear wheel frame 5, and both nut 18 and stud 10 are located in the housing 51. This can reduce the problem of contamination and corrosion of stud 10 and nut 18, thereby improving their service life.
