Description

Technical Field

[0001] The utility model relates to the technical field of electric scooters, in particular to a rear wheel shock absorbing mechanism for an electric scooter. Background Art

[0002] An electric scooter is a vehicle that is based on a traditional human-powered scooter and is equipped with an electric power kit. The working principle of an electric scooter is similar to that of an electric bicycle. It is mainly composed of a motor, a battery, and a control system. The motor usually uses a brushless motor that drives the wheels through electricity.

[0003] Compared with ordinary electric vehicles, electric scooters are relatively small in size and are usually designed to be foldable. They are widely used in the designated driver industry. Therefore, how to reduce the volume or height after folding is an important consideration for increasing the practicality of electric scooters. The rear wheel shock absorption structure of common electric scooters is almost the same as that of the front wheel, both of which are upright designs, resulting in a higher overall height. In addition, when in an upright design, shock absorption relies on the deformation of the damper, and the rear wheel bracket cannot perform any deformation buffering, and its shock absorption effect is relatively weak. Utility Model Content

[0004] The purpose of the present utility model is to provide a rear wheel shock absorbing mechanism for an electric scooter to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a pedal main frame, a rear wheel bracket and a damper, the rear wheel bracket is fixed to the rear end of the pedal main frame and is symmetrically distributed, a connecting protective cover is fixed to the upper end of the rear side of the pedal main frame, a connecting shaft is installed on the inner side of the connecting protective cover, a shaft mounting frame is fixed to the upper end of the rear wheel bracket, an end shaft is fixed on the shaft mounting frame, and the two ends of the damper are respectively rotatably connected to the end shaft and the connecting shaft.

[0006] Preferably, a folding handle bracket is installed at the front end of the pedal main frame, a front steering wheel is installed at the bottom of the folding handle bracket, and a seat cushion bracket is installed at the upper end of the rear side of the pedal main frame.

[0007] Preferably, a driving shaft is installed between the rear sides of the rear wheel brackets, and a driving rear wheel is installed on the driving shaft.

[0008] Preferably, a rear wheel baffle is fixed above the rear side of the rear wheel bracket, and the rear wheel baffle is located above the outer periphery of the driving rear wheel.

[0009] Preferably, a mounting shaft is installed between the rear wheel bracket and the pedal, and the two are rotatably connected through the mounting shaft. A bottom protection cross frame is fixed between the rear wheel bracket and below the mounting shaft. The bottom protection cross frame can shield and protect the mounting shaft to avoid damage to the mounting shaft caused by flying stones or potholes on the road.

[0010] Preferably, a shaft protection cover is fixed to the upper end of the rear wheel bracket and located on the periphery of the shaft mounting frame. The shaft protection cover can protect the end shaft to avoid rotation jamming caused by damage to the rotating connection.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the rear wheel bracket, the damper and the rear end of the pedal main frame form a triangular structure, which increases the overall stability, reduces the overall height without affecting the normal shock absorption and damping, is more conducive to the folding of the body of the foldable electric scooter, reduces the overall height, and is conducive to folding, storage and storage.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3The utility model provides a technical solution: it includes a pedal main frame 1, a rear wheel bracket 5 and a damper 9, the rear wheel bracket 5 is fixed to the rear end of the pedal main frame 1 and is symmetrically distributed, a connecting protective cover 11 is fixed to the upper end of the rear side of the pedal main frame 1, and a connecting rotating shaft 12 is installed inside the connecting protective cover 11, a rotating shaft mounting frame 15 is fixed to the upper end of the rear wheel bracket 5, and an end rotating shaft 16 is fixed on the rotating shaft mounting frame 15, and the two ends of the damper 9 are respectively rotatably connected to the end rotating shaft 16 and the connecting rotating shaft 12, a folding handle bracket 2 is installed at the front end of the pedal main frame 1, a front steering wheel 3 is installed at the bottom of the folding handle bracket 2, and a seat cushion bracket 4 is installed at the upper end of the rear side of the pedal main frame 1.

[0018] A driving shaft 14 is installed between the rear sides of the rear wheel brackets 5, and a driving rear wheel 6 is installed on the driving shaft 14. A rear wheel baffle 7 is fixed above the rear side of the rear wheel bracket 5, and the rear wheel baffle 7 is located on the outer periphery above the driving rear wheel 6. A mounting shaft 13 is installed between the rear wheel bracket 5 and the pedal, and the two are rotatably connected through the mounting shaft 13. A bottom protection cross frame 8 is fixed between the rear wheel brackets 5 and below the mounting shaft 13. A shaft protection cover 10 is fixed to the upper end of the rear wheel bracket 5 and on the outer periphery of the shaft mounting frame 15.

[0019] Working principle: When encountering road bumps during use, the driving rear wheel 6 will be lifted synchronously with the rear wheel bracket 5, and the rear wheel bracket 5 as a whole will deflect around the mounting shaft 13, thereby compressing the damper 9, and utilizing the reverse buffering force generated by the damper 9 to buffer the overall vibration and achieve the buffering purpose. During the whole process, the deformation of the damper 9 and the deformation of the rear wheel bracket 5 can achieve the buffering of the impact force to the greatest extent, thereby improving the shock absorption effect, and the impact on the rear wheel bracket 5 will also be relatively small, which plays a certain protective role. Secondly, the rear wheel bracket 5, the damper 9 and the rear end of the pedal main frame 1 are arranged into a triangular structure, so that the stability is also improved to a certain extent, and the rear side height of the entire pedal electric vehicle is reduced, so that it can be stored in a smaller space, thereby increasing the practicality of the pedal electric vehicle.
