[0002] Electric bicycles are mechatronic personal transportation vehicles that use batteries as auxiliary power and are based on ordinary bicycles, with motors, batteries, throttles, and other control components installed. In recent years, electric bicycles have been widely used in urban and rural areas due to their advantages such as environmental protection, energy saving, and convenience.

[0003] Existing electric bicycles are assembled by mounting the motor, battery, throttle, and other control components onto the frame, along with the wheels, handlebars, and other components, to form a complete electric bicycle. In use, the battery provides power to the motor and drives the rear wheel to rotate, propelling the entire vehicle forward. Alternatively, the rear wheel can be rotated by pedaling the chain, which also propels the vehicle forward.

[0004] However, since the battery is relatively exposed when mounted on the vehicle frame, it may collide with external objects when the vehicle tipes over, causing damage to the surface or interior of the battery, affecting its normal use and safety. Utility Model Content

[0005] The technical problem this utility model aims to solve is that, since the battery is relatively exposed when installed on the vehicle frame, it may collide with external objects when the vehicle tipes over, causing damage to the surface or interior of the battery, thus affecting its normal use and safety.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a frame, including a frame body, which serves as the overall support frame of an electric bicycle, wherein the frame body is used to assemble control components such as a motor, a battery, and a throttle; a battery, which is detachably installed on the frame body, wherein the battery provides power for driving the motor; and a protective component, which is detachably installed on the side of the frame body near the battery, wherein the protective component completely encloses the battery and prevents external objects from colliding with the battery.

[0007] Preferably, the protective component includes: a protective cover, which is detachably mounted on the vehicle frame body via a connecting seat and screws, wherein the protective cover encloses and protects the battery; a rubber pad, which is fixed to the protective cover and covers the surface of the protective cover to prevent objects from directly colliding with the protective cover; and a baffle, which is slidably installed inside the protective cover and is provided with a storage component, wherein the baffle is fixed by bolts after being inserted into the protective cover, wherein the nut of the bolt is fixed with a rotatable locking block.

[0008] The effect achieved by the above components is as follows: By setting up the protective assembly, firstly, the protective cover is placed on the battery, so that the connecting seat corresponds to the threaded groove on the frame body. Then, the screws are screwed into the threaded grooves on the connecting seat and the frame body to fix the protective cover. At this time, the baffle is manually inserted into the protective cover, so that the inner wall of the hole on the baffle coincides with the inner wall of the threaded groove on the protective cover. At the same time, the bolts are manually screwed into the hole on the baffle and the threaded groove on the protective cover to fix the baffle. The assembly between the baffle and the protective cover is completed, so that the protective cover, together with the baffle, completely encloses the battery and intercepts external objects, thereby protecting the battery.

[0014] The effect achieved by the above components is as follows: by setting up the storage component, items are first placed into the storage tube for storage. At this time, under the reaction force of the spring, the spring pulls the sealing plate along the inside of the storage tube towards the inside of the storage tube, so that the sealing plate is completely moved to the inside of the storage tube to seal the opening of the storage tube and intercept the items inside. This achieves convenient storage of items, reduces the situation where people have nowhere to put their items, which affects their normal riding, and improves the convenience of carrying items while riding.

[0015] Preferably, the storage component further includes a push plate, which is fixed to the sealing plate, wherein the inner side of the push plate is provided with multiple anti-slip protrusions.

[0016] The effect achieved by the above components is that by setting up the push plate, a point of leverage can be provided for personnel, increasing the convenience and stability of manually moving the sealing plate.

[0017] Preferably, the storage component further includes: reinforcing ribs, wherein the reinforcing ribs are uniformly fixed to the storage cylinder, and wherein the reinforcing ribs are made of metal.

[0018] The effect achieved by the above components is that the strength of the storage tube can be increased by setting reinforcing ribs, reducing the possibility of the storage tube breaking or denting after being hit.

After the baffle 35 is inserted into the protective cover 31, it is fixed by bolts 36, wherein the nut of the bolts 36 is fixed with a rotatable locking block 37. By setting the protective component 3, the protective cover 31 is first placed on the battery 2, so that the connecting seat 32 and the threaded groove on the frame body 1 are aligned. Correspondingly, at this time, screws are screwed into the threaded grooves on the connecting seat 32 and the frame body 1 to fix the protective cover 31. Then, the baffle 35 is manually inserted into the protective cover 31 so that the inner wall of the hole on the baffle 35 coincides with the inner wall of the threaded groove on the protective cover 31. At the same time, the bolt 36 is manually screwed into the hole on the baffle 35 and the threaded groove on the protective cover 31 to fix the baffle 35. The assembly between the baffle 35 and the protective cover 31 is completed, so that the protective cover, together with the baffle 35, completely encloses the battery 2 and intercepts external objects, thereby protecting the battery 2. This reduces the possibility of the battery 2 colliding with external objects when the vehicle is tilted, causing damage to the surface or inside of the battery 2, affecting the normal use of the battery 2, and improving the safety of the battery 2.

[0032] Figure 2 and Figure 3 The protective component 3 also includes a cooling fan 34, which is detachably mounted on the protective cover 31 by screws. The cooling fan 34 is driven by a motor to rotate and generate airflow into the protective cover 31, carrying away the heat inside the protective cover 31 through the heat dissipation holes on the protective cover 31.
