Description

Technical Field

[0001] The present application relates to the technical field of scooters, and in particular to a rear wheel cover of an electric scooter. Background Art

[0002] As a convenient tool for short-distance travel, electric scooters are becoming more and more popular in cities. However, when encountering complex road conditions, such as uphill and downhill, turning, etc., the traditional electric scooter design often affects the driving experience and safety due to the lack of stability of the rear wheel. In particular, the design of the rear wheel cover is traditionally a fixed structure that cannot be adjusted according to road conditions, limiting the adaptability and flexibility of the vehicle.

[0003] In addition, the rear wheel cover of existing electric scooters is usually designed as an integral whole, which not only increases the weight but also reduces the convenience of maintenance and replacement. There are also certain limitations for the heat dissipation and maintenance of the hub motor. Therefore, a new rear wheel cover design for electric scooters is needed to improve the stability and driving experience of the vehicle, while optimizing the structure for easy maintenance and use.

[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0005] Based on this, the present application provides a rear wheel cover for an electric scooter to solve one of the above-mentioned technical problems.

[0006] The technical solution adopted by the present application to solve its technical problems is, including: a hub motor for driving the rear wheel, with a fixed shaft installed at its axial position; a hub bracket, installed on the fixed shaft, the hub bracket provides a base for the hub motor; at least one pair of rear wheel cover brackets are provided and rotatably arranged at both ends of the fixed shaft; a split rear wheel cover, including a first rear wheel cover and a second rear wheel cover, the first rear wheel cover is installed on the hub bracket, and the second rear wheel cover is installed on the rear wheel cover bracket; an adjustment mechanism, installed on one end of the hub bracket, for adjusting the rotation angle of the second rear wheel cover.

[0007] In some embodiments, the adjustment mechanism includes a worm and a connecting plate, the connecting plate is formed on the wheel hub bracket, and the worm is rotatably disposed on the connecting plate.

[0008] In some embodiments, a plurality of teeth meshing with the worm are formed on the outer periphery of one end of the rear wheel cover bracket connected to the fixed shaft.

[0009] In some embodiments, the adjustment angle range of the adjustment mechanism is 0°-90°.

[0010] In some embodiments, a knob is provided at one end of the worm for easy rotation.

[0011] In some embodiments, the hub bracket is fixed on the fixed shaft by tightening a nut.

[0012] In some embodiments, a hollow groove is provided inside the rear wheel cover bracket.

[0013] The beneficial effects of this application are:

[0014] Firstly, by setting an adjustable second rear wheel cover and using an adjusting mechanism (such as a worm and a connecting plate) to adjust the rotation angle of the rear wheel cover (such as 0°-90°), the electric scooter can better maintain stability under different road conditions, thereby improving driving safety and flexibility.

[0015] Secondly, a split rear wheel cover design is adopted, which is divided into a first rear wheel cover and a second rear wheel cover, wherein the first rear wheel cover is mounted on the wheel hub bracket, and the second rear wheel cover is mounted on the rear wheel cover bracket. This design not only reduces the overall weight, but also improves the convenience of maintenance and replacement.

[0016] In addition, a hollow groove is opened inside the rear wheel cover bracket, which not only helps to dissipate heat from the hub motor, but also facilitates daily inspection and maintenance, extending the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0024] In the embodiments of this application, please refer to Figure 1-4 As shown, the present application provides a rear wheel cover of an electric scooter, which mainly includes: a hub motor 1, used to drive the rear wheel, and a fixed shaft 11 is installed at its axial position; a hub bracket 2, installed on the fixed shaft 11, and the hub bracket 2 provides a base for the hub motor 1; a rear wheel cover bracket 3, at least one pair of which are rotatably arranged at both ends of the fixed shaft 11; a split rear wheel cover 4, including a first rear wheel cover 41 and a second rear wheel cover 42, the first rear wheel cover 41 is installed on the hub bracket 2, and the second rear wheel cover 42 is installed on the rear wheel cover bracket 3; an adjustment mechanism 5, installed on one end of the hub bracket 2, and used to adjust the rotation angle of the second rear wheel cover 42.

[0025] Specifically, the angle of the second wheel cover can be freely adjusted to adapt to various situations. For example, in bad weather, the second wheel cover can be adjusted through the adjustment mechanism 5 to cover the wheel as much as possible, which can effectively prevent the impact of bad weather on the wheel. When the weather and road conditions are very good, the angle of the second wheel cover can be adjusted to a state that is relatively parallel to the first wheel cover, reducing the frontal area and thereby reducing energy consumption.

[0026] As an illustration, the fixed axis of the above-mentioned hub motor passes through the axis of the hub motor, and the hub motor rotates by means of bearings provided inside, so when the hub motor rotates, it will not interfere with the fixed axis.
