Description

Technical Field

[0001] This utility model relates to the field of hub motors, and more particularly to an energy storage motor applied to the hub structure of electric bicycles. Background Technology

[0002] Energy storage motors used in the hub structure of electric bicycles are usually called hub motors. Reluctance energy storage motors can also be used as hub motors. The working principle of a reluctance motor is based on the principle of minimum magnetic reluctance, that is, magnetic flux always closes along the path of least magnetic reluctance, thereby generating magnetic pull and forming electromagnetic torque with reluctance properties. This characteristic allows reluctance motors to be used as hub motors in specific applications. The motor is directly installed inside the wheel, and the rotor of the motor is connected to the wheel rim, which can directly drive the wheel to rotate. This eliminates the need for complex mechanical transmission components such as traditional transmission chains, gears, and gearboxes. Because the transmission system is eliminated, the structure of the electric bicycle is simpler, which helps to improve space utilization and transmission efficiency.

[0003] A search revealed that Chinese Patent Publication No. CN213817462U discloses an electric bicycle hub motor that utilizes hollow screws and the internal thread of the motor shaft to better secure the hub motor to the rear fork of the electric bicycle, preventing the installation screws from loosening during long-term use.

[0004] In the above technical solution, the hollow screw and the internal thread of the motor shaft can be used to easily fix the wheel motor to the bicycle, avoiding the phenomenon of loose screws in the wheel motor. However, the wheel motor lacks dustproof function, which will cause dust to accumulate inside the wheel and reduce the stability of motor operation. Therefore, an energy storage motor applied to the wheel hub structure of electric bicycle is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an energy storage motor for electric bicycle wheel hub structures, aiming to improve the problem that the lack of dustproof and wind-guiding functions for wheel hub motors in existing electric bicycle wheel hub structures leads to reduced motor operation stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy storage motor applied to the hub structure of an electric bicycle, comprising a motor, a support frame fixedly connected to the outer wall of the motor, a wheel wing fixedly connected to the outer wall of the support frame, a filter plate provided on the inner surface of the wheel wing, a through hole opened at the center of the filter plate, an adapter hole through the surface of the support frame, a fixing ring fixedly connected to the inner wall of the filter plate, a screw threadedly connected to the inner wall of the fixing ring, and an air guide assembly provided on the surface of the filter plate.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the adapter hole is threadedly connected to the outer wall of the screw.

[0009] As a further description of the above technical solution:

[0010] The outer surface of the filter plate is adapted to the inner surface of the wheel blade, and the inner wall of the through hole is adapted to the outer wall of the motor.

[0011] As a further description of the above technical solution:

[0012] The air guiding assembly includes an air guiding plate, a fixing block is fixedly connected to the outer wall of the air guiding plate, a screw is fixedly connected to the side wall of the fixing block, an installation ring is fixedly connected to the inner wall of the filter plate, and a fastening ring is threadedly connected to the inner wall of the installation ring.

[0013] As a further description of the above technical solution:

[0014] The fixing block is attached to the side of the screw that is close to the filter plate and the side that is away from the motor, and the screw passes through the filter plate.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the screw is threadedly connected to the inner wall of the fastening ring.

[0017] As a further description of the above technical solution:

[0018] The sidewall of the air guide plate is set in an arc-shaped concave shape.

[0019] As a further description of the above technical solution:

[0020] The side wall of the air guide plate is provided with a groove, and an anti-slip strip is fixedly connected to the inner wall of the groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the filter plate can be fixed on the wheel blade by providing through holes, fixing rings, screws and adapter holes. The air guide assembly can transmit the air source to the drive shaft of the motor through the air guide plate. At the same time, the tilt direction of the air guide plate can be adjusted to switch the air flow. While providing dust protection for the motor, it also provides some additional ventilation and heat dissipation assistance to the motor to ensure stable operation of the motor.

[0023] 2. In this utility model, the groove and anti-slip strip can increase the friction between the hand and the air guide plate, so that the hand will not slip when picking up the air guide plate or adjusting the orientation of the air guide plate. At the same time, the anti-slip strip is not in a raised state on the air guide plate, reducing the degree of influence on the air guide. Attached Figure Description

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of an energy storage motor applied to the hub structure of an electric bicycle, comprising a motor 1, a support frame 2 fixedly connected to the outer wall of the motor 1, several sets of support frames 2 being arranged, and the several sets of support frames 2 being evenly distributed on the inner surface of the wheel wing 3 to provide support for the motor 1, the outer wall of the support frame 2 being fixedly connected to the wheel wing 3, a filter plate 4 being provided on the inner surface of the wheel wing 3, the surface of the filter plate 4 having several sets of evenly distributed filter holes through which dust can be blocked, and a center of the filter plate 4 having a... Through hole 5, the inner wall of through hole 5 is adapted to the outer wall of motor 1. The opening of through hole 5 facilitates the insertion of filter plate 4 into the center of wheel blade 3. Adaptor hole 8 is opened through the surface of support frame 2. The inner wall of adapter hole 8 is threaded to the outer wall of screw 7. The number of adapter holes 8, screws 7 and fixing rings 6 is the same as the number of support frames 2. Fixing ring 6 is fixedly connected to the inner wall of filter plate 4. The outer surface of filter plate 4 is adapted to the inner surface of wheel blade 3. Screw 7 is threaded to the inner wall of fixing ring 6. Air guide assembly is provided on the surface of filter plate 4.

[0034] Reference Figures 4-6 The air guiding assembly includes an air guide plate 9. The sidewall of the air guide plate 9 is concave in an arc shape and is inclined on the surface of the filter plate 4 to facilitate the transmission of air source to the drive shaft of the motor 1. A fixing block 10 is fixedly connected to the outer wall of the air guide plate 9, and a screw 11 is fixedly connected to the sidewall of the fixing block 10. An installation ring 12 is fixedly connected to the inner wall of the filter plate 4, and a fastening ring 13 is threadedly connected to the inner wall of the installation ring 12. The side of the fixing block 10 near the screw 11 is in contact with the side of the filter plate 4 away from the motor 1. The fixing block 10 can increase the contact area between the air guide plate 9 and the filter plate 4, improve the contact degree between the air guide plate 9 and the filter plate 4, and thus increase the stability of the air guide plate 9 fixed on the filter plate 4. The screw 11 penetrates the filter plate 4, and the surface of the filter plate 4 is provided with holes that are adapted to the outer wall of the screw 11, so that the screw 11 can be inserted into the filter plate 4. The outer wall of the screw 11 is threadedly connected to the inner wall of the fastening ring 13. The degree to which the screw 11 is connected to the fastening ring 13 can adjust the degree of tilt of the air guide plate 9.

[0035] Reference Figure 3 The side wall of the air guide plate 9 is provided with grooves 14. Several sets of grooves 14 are provided, and the sets of grooves 14 are distributed in pairs on the outer side walls of each set of air guide plates 9. The grooves 14 facilitate the installation of multiple sets of anti-slip strips 15. Because the grooves 14 are provided, the anti-slip strips 15 will not be raised on the air guide plate 9, reducing the impact on air guidance. The inner wall of the grooves 14 is fixedly connected with anti-slip strips 15. The anti-slip strips 15 increase the friction between the operator's hand and the air guide plate 9, making it easier to grip the air guide plate 9.

[0036] Working principle: The operator inserts their fingers into the groove 14 and contacts the anti-slip strip 15 to pick up the air guide plate 9. The screw 11 is inserted into the corresponding hole of the filter plate 4, and then the fastening ring 13 is screwed into the mounting ring 12 until the inner and outer sides of the fastening ring 13 are fixed to the screw 11 and the mounting ring 12 respectively. At the same time, the tilt of the air guide plate 9 can be adjusted during the screwing of the fastening ring 13. Then, the through hole 5 is aligned with the center point of the drive shaft of the motor 1, and the filter plate 4 is inserted into the wheel wing 3 so that each set of fixing rings 6 is aligned with the adapter hole 8. Then, the screws 7 are screwed into the fixing rings 6 and the adapter hole 8 in sequence to fix the filter plate 4 on the wheel wing 3. This can provide dust protection for the motor 1. At the same time, the concave part of the multiple sets of air guide plates 9 can transmit the air source to the drive shaft of the motor 1, providing some additional heat dissipation for the motor 1 and ensuring the operation of the motor 1.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
