Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to an electric motorcycle hub motor with a reinforced frame. Background Technology
[0002] A hub motor is a motor designed to integrate a vehicle's power system, transmission system, and braking system. As the name suggests, a hub motor is both a wheel hub and a motor; the motor and the wheel hub are combined into one. The working principle of a hub motor is to install the motor directly inside the wheel hub and drive the wheel to rotate by converting electrical energy into mechanical energy.
[0003] Most hub motors have side covers on both sides with ventilation holes for heat dissipation. However, the side covers are usually thin, and the ventilation holes themselves greatly affect their strength. Therefore, the side covers are easily deformed and damaged by collisions with external objects, which can affect the motor. Utility Model Content
[0004] The purpose of this utility model is to provide an electric motorcycle hub motor with a reinforced frame in order to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An electric motorcycle hub motor with a reinforced frame includes a wheel hub and a motor disposed inside the wheel hub. The motor has end caps on both sides, and the end caps are fixedly connected to the motor housing by a plurality of first bolts. The inner side of the wheel hub is provided with a reinforcing component that cooperates with the two sides of the motor.
[0007] As a further description of the above technical solution:
[0008] The reinforcement assembly includes an outer reinforcement ring and an inner reinforcement ring, which are fixedly connected by multiple reinforcing ribs. The inner reinforcement ring is fixedly connected to the end cap by multiple second bolts, and the outer reinforcement ring is fixedly connected to the wheel hub by multiple third bolts.
[0009] As a further description of the above technical solution:
[0010] The reinforcement component also includes an inner lining reinforcement ring, which is fixedly connected to the reinforcing rib at the joint.
[0011] As a further description of the above technical solution:
[0012] Multiple connecting cylinders are fixedly provided inside the inner lining reinforcing ring. The multiple connecting cylinders are arranged in a ring array. One end of each connecting cylinder passes through the outer side of the inner lining reinforcing ring and is open. A fourth bolt is provided inside each connecting cylinder. One end of the fourth bolt passes through the other end of the connecting cylinder and is fixedly connected to the motor housing.
[0013] As a further description of the above technical solution:
[0014] One end of each of the connecting cylinders abuts against the outer surface of the end cap, and the surface of the end cap is provided with a mounting hole for the fourth bolt to pass through.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0016] In this invention, by setting an outer reinforcing ring, an inner reinforcing ring, and reinforcing ribs, the strength of the wheel hub is improved on the one hand, and the motor is further protected on the other hand, preventing objects in the external environment from colliding with the motor and causing damage. By setting an inner reinforcing ring and a connecting cylinder, the reinforcing ribs are supported, further improving the overall strength of the outer reinforcing ring, inner reinforcing ring, and reinforcing ribs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-3As shown, an electric motorcycle hub motor with a reinforced frame includes a wheel hub 1 and a motor 3 disposed inside the wheel hub 1. The motor 3 has end caps 4 on both sides, and the end caps 4 are fixedly connected to the outer shell of the motor 3 by multiple first bolts 9. The inner side of the wheel hub 1 is provided with reinforcing components that cooperate with the two sides of the motor 3.
[0023] Furthermore, the reinforcement assembly includes an outer reinforcement ring 2 and an inner reinforcement ring 5. The outer reinforcement ring 2 and the inner reinforcement ring 5 are fixedly connected by multiple reinforcing ribs 6. The inner reinforcement ring 5 is fixedly connected to the end cap 4 by multiple second bolts 10. The outer reinforcement ring 2 is fixedly connected to the wheel hub 1 by multiple third bolts 11. In use, the outer reinforcement ring 2, the inner reinforcement ring 5, and the reinforcing ribs 6 form a whole installed inside the wheel hub 1, which effectively improves the strength of the wheel hub 1 and achieves the effect of further protecting the motor 3.
[0024] Furthermore, the reinforcement component also includes an inner lining reinforcement ring 7, which is fixedly connected to the reinforcing rib 6 at the joint. By setting the inner lining reinforcement ring 7, the middle part of the reinforcing rib 6 is supported, thereby improving the overall tensile strength of the reinforcing rib 6 and effectively preventing the reinforcing rib 6 from bending and deforming.
[0025] Furthermore, multiple connecting cylinders 8 are fixedly provided on the inner side of the inner lining reinforcing ring 7. The multiple connecting cylinders 8 are arranged in a ring array. One end of the multiple connecting cylinders 8 passes through the outer side of the inner lining reinforcing ring 7 and is open. A fourth bolt 12 is provided inside the multiple connecting cylinders 8. One end of the fourth bolt 12 passes through the other end of the connecting cylinder 8 and is fixedly connected to the outer shell of the motor 3. By setting multiple connecting cylinders 8, the reinforcing and supporting effect is achieved, ensuring the supporting strength of the inner lining reinforcing ring 7.
[0026] Furthermore, one end of each of the multiple connecting cylinders 8 abuts against the outer surface of the end cap 4, and the surface of the end cap 4 is provided with a mounting hole for the fourth bolt 12 to pass through. By installing the fourth bolt 12 through the end cap 4, the installation strength is further improved.
