Description

Battery Seat Structure for Electric Bicycle Technical Field

[0001] This creation relates to a "battery seat structure for electric bicycle", especially a battery structure for electric bicycle with a hand-cranked power generation function. Prior Art

[0002] Electric bicycles have environmental protection characteristics such as low pollution, low carbon emissions, and low noise. They can replace limited petroleum with the most easily obtainable electricity, reduce the impact of carbon dioxide on the earth, and mitigate climate change brought by greenhouse gases. In addition, the electric bicycle industry can also drive the supply of related spare parts and the investment of related human resources to increase the overall employment market. Therefore, governments of various countries are happy to see the booming development of this industry and hope to use electric bicycles to suppress the use of cars and motorcycles.

[0003] However, since an electric bicycle relies entirely on the electricity stored in the storage battery in the battery pack when driving, once the power of the battery pack is exhausted and there is a lack of charging equipment in the surrounding environment (such as being in the suburbs), the electric bicycle cannot continue to provide riding. Moreover, due to the heavy weight of the electric bicycle, it will be a great burden to pedal or tow it back to the charging place by manpower alone. Furthermore, when the battery pack enters the low-voltage protection or runs out of power completely, in-vehicle electronic devices such as GPS and intelligent networking will also lose power accordingly, which will cause the vehicle to be unable to send a positioning signal when trapped in the wild. Therefore, how to increase the diversity of power acquisition and improve the endurance of the electric bicycle is the problem that the creator wants to improve.

[0004] Therefore, in view of this, the creator had the idea of creation, and then designed it with years of experience, explored and tested samples in many ways, and made multiple corrections and improvements, and finally launched this creation. Summary of the Invention Problems to be Solved by the Invention

[0005] Means for Solving the Problems

[0006]

[0007] The present creation provides a battery seat structure for an electric bicycle, which includes: an electric bicycle and a battery unit. Among them, the electric bicycle has a vehicle frame, two wheels, an assist motor and two pedals. Fork parts are formed at the front and rear of the vehicle frame. A wheel axle is provided in the center of the wheel body. By using the fork parts to pivotally connect the wheel axle, the wheel body can be positioned on the vehicle frame in a rotatable manner. Moreover, the assist motor is provided on one of the wheel bodies and is electrically connected to the battery unit installed on the vehicle frame. Through the battery unit providing the power required for the operation of the assist motor, the electric bicycle can use the assist motor to provide auxiliary output during the riding process of pedaling the pedals, and at the same time, it can also recharge the battery unit through the power generation of the assist motor. The battery unit has a battery seat, a battery pack and a battery box. The battery seat is fixed on the vehicle frame of the electric bicycle. The battery pack is accommodated inside the battery box. A solar film is combined on the outer surface of the battery box, and a charging hole is reserved. By using the battery box to be detachably arranged on the battery seat, the battery box together with the battery pack can be removed from the battery seat, so as to connect a power source through the charging hole to charge the battery pack. Moreover, a hand-crank generator is provided in the battery seat. When the power is exhausted during riding, a rocker arm can be connected by using the hand-crank generator, and the battery pack can be emergently charged through the hand-crank generator by rotating the rocker arm. Thus, a battery seat structure for an electric bicycle can be obtained. Effect of the Invention

[0008]

[0009] (1) The present creation provides a battery seat structure for an electric bicycle. In addition to the battery pack being able to be recharged through the assist motor, charged by solar energy through the solar film and obtaining external power through the charging hole, when the power of the battery pack is exhausted, a rocker arm can be connected by using the hand-crank generator, and the battery pack can be emergently charged through the hand-crank generator by rotating the rocker arm. In this way, there is no problem that the electric bicycle runs out of power completely and it is necessary to exert force to push it back or ride it back. The convenience of use is good, and the acquisition of electric energy is also more diverse.

[0010] (2) The present creation provides a battery seat structure for an electric bicycle. Using the hand-crank generator for emergency charging can prevent the communication module or various in-vehicle electronic devices from failing due to the electric bicycle running out of power completely, so as to achieve the specific effect that the vehicle can still normally emit positioning signals or communicate when trapped in the wild.

[0017] To enable your review committee to gain a better understanding of the purpose, features, and effects of this work, the following examples, accompanied by simplified illustrations, are provided and explained in detail:

[0018] First, as shown in Figures 1 to 3, it includes: an electric bicycle (10) and a battery unit (20). The electric bicycle (10) has a frame (11), two wheels (12), a power assist motor (13), and two pedals (14). The frame (11) has a fork (111) at both the front and rear. The wheel (12) has an axle (121) in the center. The fork (111) provides a pivot for the axle (121), allowing the wheel (12) to be rotatably positioned on the axle. The frame (11) and the power assist motor (13) are mounted on a wheel (12) and electrically connected to the battery unit (20) mounted on the frame (11). The battery unit (20) provides the power required for the power assist motor (13) to operate, allowing the electric bicycle (10) to use the power assist motor (13) to provide auxiliary power during the pedaling process (14). Simultaneously, the power generated by the power assist motor (13) can recharge the battery unit (20). The battery unit (20) has a battery holder (21), a battery pack (22), and a battery box (23). The battery holder (21) is fixed to the frame (11) of the electric bicycle (10). The battery pack (22) is housed inside the battery box (23). A solar film (24) is bonded to the outer surface of the battery box (23), and a charging port (231) is provided. The battery box (23) is detachably mounted on the battery holder (21), allowing the battery box (23) and the battery pack to be detachably mounted together. The battery pack (22) can be removed from the battery holder (21) so that it can be connected to a power source (mains power) through the charging port (231) to charge the battery pack (22). The battery holder (21) is equipped with a hand-cranked generator (211). When the power is exhausted during riding, the hand-cranked generator (211) can be used to connect a rocker arm (30) so that the battery pack (22) can be charged in an emergency by rotating the rocker arm (30) via the hand-cranked generator (211) (please see Figures 4 and 5 at the same time).

[0024] This invention provides a battery holder structure for an electric bicycle, wherein the solar thin film (24) is simultaneously bonded to the top surface and both sides of the battery box (23).

[0025] By means of the structure of the above specific embodiment, the following benefits can be obtained: (i) In addition to being able to recharge the battery pack (22) through the power assist motor (13), to charge the solar film (24) through solar energy, and to obtain external power through the charging port (231), when the battery pack (22) is depleted, a rocker arm (30) is provided by the hand-cranked generator (211) for connection, and the battery pack is powered by rotating the rocker arm (30) via the hand-cranked generator (211). (22) Emergency charging is performed, so that there is no problem of having to push or ride the electric bicycle (10) back when it runs out of power. It is more convenient to use and the power acquisition is more diverse. (ii) The use of the hand-cranked generator (211) for emergency charging can prevent the communication module (212) or various electronic devices on the vehicle from failing when the electric bicycle (10) runs out of power. This achieves the specific effect of the vehicle being able to send a positioning signal or communicate normally when it is stuck in the wild.
