Description

Technical Field

[0001] This utility model belongs to the field of battery box technology, and in particular relates to a battery box with an integrated control micro switch and a convenient detachable base. Background Technology

[0002] An electric-assisted bicycle is a type of bicycle that combines human and electric power. It is similar in shape and structure to a traditional bicycle, with pedals, but it is equipped with batteries and motors to provide assistance to the user through electricity, making riding easier and less strenuous.

[0003] The battery box is an important component on an electric bicycle used to protect the battery. Ordinary battery boxes do not have microswitches, and the battery's power output port is always powered. When the power output port connector is connected to the external controller's input port connector, sparking will occur, damaging the connector.

[0004] In addition, the battery box is fixed to the electric bicycle via a base, and the connection between the base and the battery box is complicated, making the assembly of the base and the battery box inconvenient. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a battery box in which the base is inserted into the lower part of the lower cover. The connection between the lower cover and the base is achieved by the snap-fit ​​block at the lower part of the lower cover and the snap-fit ​​parts on both sides of the base. Rotating the lock cylinder counterclockwise by 180° causes the drive column to rotate from the highest position to the lowest position. The elastic element in the compressed state recovers its deformation and drives the lock tongue to move downward. The lock tongue engages with the base to restrict the movement of the base. Rotating the locking part counterclockwise by 180° causes the drive column to rotate from the lowest position to the highest position. The locking part contacts the micro switch to drive the micro switch to open. The drive column can also press the lock tongue to prevent the lock tongue from retracting and disengaging from the limiting groove. This achieves an integrated locking base and triggering micro switch, which can shut off the power output and ensure that the output port plug will not be damaged by arcing when it is connected. The connection between the base and the battery box is simple and the assembly between the base and the battery box is convenient.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a battery box, the battery box comprising:

[0007] Top cover;

[0008] The lower cover is connected to the upper cover by a number of locking components, and the upper cover and the lower cover together form a battery cavity for storing batteries;

[0009] A base that snaps into the lower part of the lower cover;

[0010] A locking part is provided inside the lower cover, and a micro switch is also provided inside the lower cover;

[0011] Rotate the locking part counterclockwise 180°, and the locking part will engage with the base to restrict the movement of the base;

[0012] Rotate the locking part counterclockwise 180°, and the locking part will contact the micro switch to drive the micro switch to open.

[0013] Preferably, the locking part includes a drive assembly and a locking assembly;

[0014] The drive assembly includes a lock cylinder, a drive shaft, a cam, and a drive disc. The drive shaft is located at the end of the lock cylinder, the cam is sleeved on the outer periphery of the drive shaft, the drive disc is located at the end of the drive shaft, and a drive post is provided at the end of the drive disc away from the drive shaft.

[0015] The locking assembly includes a latch and an elastic element. The elastic element is disposed on the upper part of the latch. A connecting block that cooperates with the drive post is disposed on the upper part of one side of the latch. A limit block is also disposed on one side of the latch.

[0016] Preferably, the lower cover is provided with a first mounting cavity and a second mounting cavity, the first mounting cavity and the second mounting cavity are arranged perpendicularly, and the first mounting cavity and the second mounting cavity are connected.

[0017] Preferably, a first limiting pin is provided on one side of the first mounting cavity, and an elastic element and a locking tongue are sequentially arranged in the first mounting cavity, and the first limiting pin contacts the limiting block to restrict the downward movement of the locking tongue;

[0018] A second limiting pin is provided on one side of the second mounting cavity. The lock cylinder, drive shaft, cam and drive disk are sequentially arranged in the second mounting cavity. One end of the second limiting pin is located between the cam and the drive disk, and is used to restrict the movement of the cam and the drive disk along the axial direction of the drive shaft.

[0019] Preferably, the lower part of the lower cover is provided with a mounting groove, and several snap-fit ​​blocks are symmetrically arranged on both sides of the mounting groove.

[0020] Preferably, the upper part of the base is provided with a limiting groove that matches the locking tongue to limit the movement of the base, and several plug-in parts are symmetrically arranged on both sides of the base. The plug-in parts include a horizontally arranged guide strip and a limiting piece disposed at the end of the guide strip. The guide strip is engaged with the locking block, and the limiting piece contacts the locking block to limit the movement of the base.

[0021] The beneficial effects of this utility model are as follows:

[0022] Insert the base into the lower part of the cover. The lower cover engages with the inserts on both sides of the base via the snap-fit ​​block at the bottom of the cover. This connects the cover and the base. Rotate the lock cylinder 180° counterclockwise. The drive column rotates from the highest position to the lowest position. The compressed elastic element recovers its deformation and drives the bolt to move downward. The bolt engages with the base to restrict its movement. The connection between the base and the battery box is simple, and the assembly between them is convenient.

[0023] Additionally, rotating the locking part counterclockwise by 180° causes the drive column to rotate from the lowest position to the highest position. The locking part then contacts the micro switch, driving it to open. The drive column also presses down on the latch to prevent it from retracting and disengaging from the limiting groove. In this state, the latch cannot retract, and the battery discharge terminal has an output. The battery-loaded base in this state cannot be properly installed into the battery cavity, as the fixed latch will interfere. This also prevents the plug terminals from sparking when the battery is plugged in or unplugged during power-on. Attached Figure Description
