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 easy-to-remove outer cover. Background Technology

[0002] Electric bicycles typically require a battery box for power supply. Currently, most electric bicycles use lithium batteries installed inside the downtube of the frame to make efficient use of space and achieve a smaller, lighter design. Generally, the battery box needs to be secured inside the downtube using a lock. For aesthetic reasons, the outer cover is usually not designed with handles, which makes it difficult for the operator to remove the outer cover without any handles to grip. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a battery box with an easy-to-remove outer cover. When the battery box needs to be removed, the operator pushes the slider to move, the slider causes the second locking tongue to separate from the opening, and the first elastic element pops up the outer cover, making it convenient for the operator to remove the outer cover.

[0034] Example: Refer to Figures 1-5 As shown, a battery box with an easily removable outer cover includes:

[0035] The lower tube 100 is a hollow tube, and the upper part of the lower tube 100 is provided with an opening 101.

[0036] The base 200 is disposed at the bottom of the lower tube 100. The base 200 includes a front seat 201 and a rear seat 202. Both the front seat 201 and the rear seat 202 are disposed at the bottom of the lower tube 100. The front seat 201 is provided with a slot 2011.

[0037] A battery box 300 is disposed between the front seat 201 and the rear seat 202. A locking part 400 is provided at one end of the battery box 300 near the front seat 201. The locking part 400 engages with the slot 2011. A first elastic member 500 is also provided on the upper part of the end of the battery box 300 near the front seat 201.

[0038] The outer cover plate 600 matches the opening 101. The outer cover plate 600 can press the first elastic member 500 between the outer cover plate 600 and the battery box 300, and the outer cover plate 600 is engaged with the opening 101.

[0039] Furthermore, the battery box 300 has a threaded hole 301 at one end, a through hole 501 at one end of the elastic element, and a fixing element 700 on one side of the elastic element. The fixing element 700 is locked to the threaded hole 301 by bolts passing through the fixing element 700 and the through hole 501 in sequence.

[0040] In addition, the locking part 400 includes a first locking tongue 401, a limiting member 402 and a second elastic member 403, and a first mounting groove 302 is provided at one end of the battery box 300;

[0041] The first locking tongue 401 is provided with a through groove 4011, and the limiting member 402 passes through the through groove 4011 and is connected to the battery box 300. The limiting member 402 can restrict the movement of the first locking tongue 401. The upper part of the first locking tongue 401 is also provided with a handle 4012.

[0042] The second elastic element 403 is disposed between the first locking tongue 401 and the first mounting groove 302.

[0043] Move the handle 4012, and the handle 4012 will cause the first locking tongue 401 to separate from the slot 2011. Then, by pulling the first elastic element 500, one end of the battery box 300 can be lifted up, making it easy to remove the battery box 300 and saving the operator's physical strength.

The fixed front seat 605 is located at the lower part of the outer cover plate 600, and the fourth elastic element 604 is located between the second locking tongue 603 and the fixed front seat 605.

[0048] The rear seat 202 is provided with a card connector 2021, and the battery box 300 is provided with a card slot 303 at one end near the rear seat 202. The card connector 2021 is matched with the card slot 303.

[0049] The working principle of this utility model is as follows:

[0050] 1. The slider 602 drives the second locking tongue 603 to retract into the fixed front seat 605. The second locking tongue 603 separates from the opening 101 of the lower tube 100. The first elastic element 500 pops up the outer cover plate 600, and the operator separates the outer cover plate 600 from the lower tube 100.

[0051] 2. The operator moves the handle 4012, which causes the first locking tongue 401 to separate from the slot 2011. Then, by pulling the first elastic element 500, one end of the battery box 300 is lifted, and the operator removes the battery box 300.
