Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

A battery pack and a battery-powered device according to an embodiment of the present invention will be described with reference to fig. 1 to 5.

In one aspect, the present invention provides a battery box, as shown in fig. 1-3, comprising a battery box body 1, a box cover 2, and a positive terminal 3 and a negative terminal 4 disposed oppositely.

The battery cartridge body 1 has a receiving chamber 11 for receiving the battery 100, and the cartridge cover 2 is fitted to the battery cartridge body 1 for opening or closing the receiving chamber 11. At least one pair of the positive and negative terminals 3 and 4 may be mounted in the receiving cavity 11, for example, two pairs of the positive and negative terminals 3 and 4 are provided in the battery case as shown in fig. 1.

As one of the embodiments of the present application, the positive terminal 3 is a positive tab, and the negative terminal 4 includes a spring 41 and a negative tab 42 connected to the spring 41. Of course, the positive terminal 3 and the negative terminal 4 are not limited thereto, and may be other positive or negative terminals of other structures or types in the prior art, for example, the positive terminal is a spring piece, and the negative terminal only includes a spring.

As shown in fig. 4, generally, a battery 100 has a battery body 101 and a positive electrode cap 102 protruding from the battery body 101. In fig. 4, a is the length of the positive electrode cap 102, B is the length of the battery body 101, C is the length of the battery 100, and D is the diameter of the positive electrode cap 102.

As shown in fig. 5, the spring 41 has a first portion 411 and a diameter smaller than the diameter D of the positive electrode cap 102; the first portion 411 of the spring 41 in the extreme compressed state is spaced from the positive terminal 3 by a distance greater than the length B of the battery body 101 and less than the length C of the battery.

The diameter of the middle spring 41 of the present invention refers to the inner diameter of the spring 41, and the diameters of the portions of the spring 41 may be the same or different, so that the diameter of the first portion 411 of the spring 41 may be the same or varied, but should be smaller than the diameter D of the positive electrode cap 102. The free state of the spring 41 is a state in which the spring is not compressed, and the limit compression state of the spring 41 is a state in which the spring 41 is compressed until it cannot be further compressed. The distance between the first portion 411 or the second portion 412 and the positive terminal 3 refers to a linear distance between one end of the first portion 411 or the second portion 412 closer to the positive terminal 3 and the positive terminal 3. Further, the diameter of the first portion 411 of the spring 41 is made substantially the same. Since the diameter of the first portion 411 is substantially the same, forming an incompressible segment at the extreme compression of the spring 41 better presses against the positive electrode when the battery 100 is flipped.

In some embodiments of the present invention, as shown in fig. 5, the spring 41 further has a second portion 412 connected to the first portion 411, and the diameter of the second portion 412 is larger than that of the first portion 411, so that the spring 41 has good stability or electrical contact effect when used for fixing the battery 100 by providing the second portion 412 larger than that of the first portion 411. As for the relative positions of the first portion 411 and the second portion 412 of the spring 41, the first portion 411 is located on one side of the spring 41 close to the positive terminal 3, and the second portion 412 is fixedly connected with the negative pole piece 42; or as shown in fig. 1-3, the second portion 412 is located on the side of the spring 41 near the positive terminal 3 so that the second portion 412 has good electrical contact and stability when compressed against the negative pole of the battery 100. In addition, it is understood that, in order to enable the spring 41 to function, the end of the spring 41 in the free state close to the positive terminal 3 should be spaced from the positive terminal 3 by a distance smaller than the length C of the battery 100.

In addition, in order for the second portion 412 to have good electrical contact and stability when compressing the negative electrode of the battery 100, the second portion 412 of the spring 41 may further have a diameter larger than the positive electrode cap 102, and the positive electrode cap 102 can enter into the second portion 412 in the case where the battery 100 is flipped.

In the present invention, the length of the second portion 412 in the extreme compression state may be greater than or not greater than the length of the positive electrode cap 102. Further, the length of the second part 412 in the extreme compression state is not greater than the length of the positive electrode cap 102, in this case, when the battery 100 is flipped, the positive electrode cap 102 enters the second part 412 and then presses against the first part 411, so that the battery 100 can be better prevented from being loaded into the battery box in the flipped state.

The case of the battery 100 being installed or disassembled will be described below by taking as an example the case where the second portion 412 is located on the side of the spring 41 close to the positive terminal 3, the first portion 411 is fixed to the negative plate 42, the diameter of the second portion 412 is larger than the diameter D of the positive cap, and the length of the second portion 412 in the extreme compression state is not larger than the length a of the positive cap 102, as shown in fig. 1 to 3.

In the normal mounting, the negative electrode of the battery 100 is first contacted with the second part 412 of the spring 41, and then the spring 41 is compressed so that the battery 100 is mounted in the receiving cavity 11 of the battery case body 1 with the positive electrode thereof pressed against the positive terminal 3.

When reversely assembling, the positive electrode cap 102 of the battery 100 is inserted into the second part 412 of the spring 412, and compresses the spring 41 to the limit compression state, because the length of the second part 412 in the limit compression state is not more than the length of the positive electrode cap 102, the first part 411 is pressed against the positive electrode cap 102 of the battery 100, and because the distance between the first part 411 and the positive electrode terminal 3 in the limit compression state is more than the length B of the battery body 101 and less than the length C of the battery, the battery 100 can not be smoothly assembled into the accommodating space 11, thereby avoiding the reversely assembling of the battery 100. And the cover 2 has no means to cover, the user can recognize that the battery is reversely mounted.

In addition, it can be understood that if the length of the second portion 412 in the extreme compression state is greater than the length a of the positive electrode cap 102, the first portion 411 does not contact the positive electrode cap 102 in the extreme compression state and is pressed against the battery body 101 by the second portion 412, but since the distance between the first portion 411 and the positive electrode terminal 3 is greater than the length B of the battery body 101 and less than the length C of the battery 100, the battery 100 cannot be smoothly installed in the accommodating space 11, and the battery 100 can be prevented from being reversely installed.

In some embodiments of the present invention, the battery case 1 has a protruding member 12 on the side of the positive terminal 3, and the protruding member 12 forms a mounting groove (not shown) for mounting the positive terminal 3. In the embodiment shown in fig. 1 to 3, the cross section of the protruding member 12 is L-shaped, but the shape of the protruding member 12 is not limited thereto, and may vary according to the shape or structure of the positive electrode terminal 3. The two L-shaped projections 12 form respective recesses for mounting the positive plates of the positive terminal 3. Likewise, the battery case 1 may be provided with a protrusion 14 at one side of the negative terminal 4 for mounting the negative electrode tab 42 of the negative terminal 4.

In some embodiments of the present invention, the battery box 1 has the limiting member 13 on the side of the positive terminal 3, the distance between the limiting member 13 and the positive terminal 3 is less than the length a of the positive cap 102, and the distance between the limiting member 13 and the first portion 411 of the spring 41 in the limit compression state is greater than the length B of the battery body 101 and less than the length C of the battery 100. The distance between the stopper 13 and the positive terminal 3 refers to a linear distance between the farthest position of the stopper 13 from the positive terminal 3 and the positive terminal 3, and the distance between the stopper 13 and the first portion 411 or the second portion 412 refers to a linear distance between the farthest position of the stopper 13 from the positive terminal 3 and one end of the first portion 411 or the second portion 412 closer to the positive terminal 3. In an embodiment, the limiting member 13 is formed by extending a portion of the protruding member 12 to the accommodating cavity 11, but the forming manner of the limiting member 13 is not limited to this, and for example, the limiting member can be formed by extending to the accommodating cavity 11 directly on the inner wall of the accommodating cavity 11 formed by the battery box 1. And although the limiting member 13 shown in fig. 3 has a strip shape, it may also have other suitable shapes such as a limiting point, a limiting member, etc. By making the distance between the stopper 13 and the positive terminal 3 smaller than the length B of the positive cap 102, the positive cap 102 of the battery 100 is not affected to make electrical contact with the positive terminal 3 when being mounted. The distance between the limiting piece 13 and the first part 411 of the spring 41 in the limit compression state is larger than the length B of the battery body 101 and smaller than the length C of the battery 100, so that the limiting piece 13 limits the battery 100 when the battery 100 is reversely mounted, the battery 100 cannot be smoothly mounted in the accommodating space 11, and the reverse mounting of the battery can be better avoided.
