Technical Field

[0001] This utility model relates to the field of electric bicycle battery disassembly technology, and in particular to an anti-drop structure for electric bicycle battery disassembly. Background Technology

[0002] In the daily use of electric bicycles (referred to as electric-assisted bicycles), the battery is the core power source, and the ease and safety of its installation and removal directly affect the user experience and vehicle maintenance management.

[0003] However, existing electric bicycle battery designs often use a bottom-removal method, where the battery detaches directly under gravity after the user performs a specific operation (such as unlocking with a key). This method can cause physical damage to the battery itself, affecting its lifespan. Furthermore, a battery that suddenly falls may pose a safety hazard to the user or the surrounding environment, such as injuring the user or damaging nearby property. Utility Model Content

[0004] This utility model proposes a battery removal and anti-drop structure for electric-assisted bicycles, which solves the existing problems.

[0006] The fixing bolt is provided with a sliding groove, and the first base is provided with a limiting screw that cooperates with the sliding groove.

[0007] The first base is provided with a lock, which includes a latch and a first spring for the latch to return to its original position. The latch is used to lock and unlock the battery. The cover plate is provided with a first groove that cooperates with the latch.

[0008] One end of the fixing bolt is provided with a guide surface that cooperates with the cover plate.

[0009] The beneficial effects of this utility model are as follows: The device installs the battery through the cooperation of the first base and the cover plate. By turning the key, the locking tongue extends and retracts into the first groove of the cover plate to form the first fixing structure. Then, the fixing bolt is inserted into the second groove of the cover plate to form the second fixing structure. By turning the key, the locking tongue retracts to release the first fixing structure. Then, pressing the button pushes the fixing bolt back to release the second fixing structure through the top block. This allows the battery to be safely removed under gravity and user operation. In the release sequence, the user needs to keep pressing the button to release the second fixing structure, thus ensuring that the battery is supported by the user's hand and will not fall directly. This effectively prevents the battery from accidentally falling during the disassembly process, providing a dual fixing mechanism and improving the user experience and safety.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 9 As shown, an anti-drop structure for the battery of an electric-assisted bicycle is disclosed. The structure includes a lower tube 1 for accommodating a battery 5. A first base 2 and a second base 3 for fixing the battery 5 are respectively provided at both ends inside the lower tube 1. A fixing device is provided on one side of the first base 2. Figure 5 As shown, the fixing device includes a fixing bolt 6 slidably disposed in the first base 2, a cover plate 8 fixed to one end of the battery 5, and a housing 11 enclosing the battery 5. A button 9 is provided on the housing 11. One end of the button 9 is flush with the outer wall of the housing 11, and the other end extends into the cover plate 8 and abuts against the cover plate 8 through a third spring 901. A second groove 802 is provided on the cover plate 8. A top block 10 is slidably disposed in the second groove 802. The top block 10 is fixed to the button 9. An inclined surface 12 is provided on the top block 10. One end of the fixing bolt 6 abuts against the first base 2 through a second spring 7, and the other end extends out of the first base 2 and abuts against the inclined surface 12 on the top block 10. The sliding direction of the fixing bolt 6 is perpendicular to the sliding direction of the top block 10.

[0022] like Figure 2 , Figure 8 As shown, in order to ensure the stable fixation of the fixing bolt 6 and its effective reset after sliding, the fixing bolt 6 is provided with a sliding groove 13, and the first base 2 is provided with a limiting screw 14 that cooperates with the sliding groove 13.

[0023] A lock 4 is provided on the first base 2. The lock 4 includes a latch 401 and a first spring 402 for resetting the latch 401. The latch 401 is used to lock and unlock the battery 5. A first groove 801 is provided on the cover plate 8 to cooperate with the latch 401. The latch 401 in the lock 4 is pushed by the first spring 402 to match and engage with the first groove 801 when the key is turned. When the user turns the lock 4 with the key, the latch 401 extends and retracts. The locking and fixing operation is completed by the latch 401 cooperating with the first groove 801 on the cover plate 8.

[0024] To facilitate the installation of battery 5, the fixing bolt 6 can automatically retract into the first base 2 under the action of the cover plate 8. A guide surface 15 that cooperates with the cover plate 8 is provided at one end of the fixing bolt 6. That is, when actually installing battery 5, the cover plate 8 is placed on the guide surface 15 of the fixing bolt 6. Under the force of the cover plate 8 on the guide surface 15 of the fixing bolt 6, the fixing bolt 6 is forcibly pressed back into the first base 2. When the fixing bolt 6 is aligned with the second groove 802, it extends into the second groove 802 under the action of the second spring 7, thereby fixing battery 5.

[0025] Working principle: First, the battery 5 is installed inside the lower tube 1. The fixing bolt 6 is inserted into the second groove 802 of the cover plate 8 as the first fixing structure. The locking tongue 401 is inserted into the first groove 801 of the cover plate 8 as the second fixing structure. When removing the battery 5, turning the key causes the locking tongue 401 to retract, releasing the first fixing structure. After the first fixing structure is released, the battery 5 may fall a distance or remain fixed. At this time, the fixing bolt 6 is still stuck in the second groove 802 of the cover plate 8, so it will not fall directly to the ground. The user presses the button 9 with one hand and holds the battery 5 with the other hand. The button 9 moves the top block 10 and compresses the third spring 901. The inclined surface 12 on the top block 10 contacts the fixing bolt 6. The top block 10 pushes the fixing bolt 6 to move and compress the second spring 7. When the fixing bolt 6 is pressed out of the second groove 802, the cover plate 8 is completely separated from the first base 2, and the second fixing structure is released. At this time, the user's hand is still holding the battery 5, and the user can safely remove the battery 5 by hand.

[0026] The beneficial effects of this utility model are as follows: the battery 5 is installed by the cooperation of the first base 2 and the cover plate 8. By turning the key, the locking tongue 401 is extended and inserted into the first groove 801 of the cover plate 8 to form the first fixing structure. Then, the fixing bolt 6 is inserted into the second groove 802 of the cover plate 8 to form the second fixing structure. By turning the key, the locking tongue 401 is retracted to release the first fixing structure. Then, pressing the button 9 pushes the fixing bolt 6 to retract through the top block 10 to release the second fixing structure. This allows the battery 5 to be safely removed under gravity and user operation. In the release sequence, the user needs to keep pressing the button 9 to release the fixing structure, thus ensuring that the battery 5 is held by the user's hand and will not fall directly. This effectively prevents the battery from falling accidentally during the disassembly process, providing a double fixing mechanism and improving the user experience and safety.
