In order to describe the technical scheme of the application, the following description is made with reference to specific drawings and embodiments.

Referring to fig. 1 to 3, a first aspect embodiment of the present application provides a battery compartment 100 for accommodating a battery, the battery compartment 100 including a housing 10, a positive electrode conductor 20, and a negative electrode conductor 30.

The housing 10 is used to house a battery and also to provide a fixed basis for the positive and negative conductors 20, 30, and the housing 10 may be a separate component or may be part of the housing of the door magnetic device 200; the shape of the housing 10 may be cubic, cylindrical or other shape, and may be determined according to the shape of the door magnetic device 200; because the housing 10 is required to provide a fixed base for the positive and negative conductors 20, 30, the housing 10 is preferably made of a relatively high resistivity material, such as plastic or the like.

The positive electrode conductor 20 and the negative electrode conductor 30 are accommodated in the shell 10, the positive electrode conductor 20 and the negative electrode conductor 30 are oppositely arranged at intervals, the battery can be placed between the positive electrode conductor 20 and the negative electrode conductor 30, and the battery can be simultaneously contacted with the positive electrode conductor 20 and the negative electrode conductor 30 so as to realize the conduction and the power supply of a circuit; the positive electrode conductor 20 and the negative electrode conductor 30 may be elastic conductive members, for example, metal spring pieces, metal springs, or the like, and the positive electrode conductor 20 and the negative electrode conductor 30 may be inelastic conductive members, for example, metal sheets, or the like.

It will be appreciated that the positive and negative poles of the cell are distributed in the axial direction of the cell, so that the positive and negative conductors 20, 30 are also spaced in the axial direction of the cell.

The shell 10 is internally provided with an anti-reverse mounting structure 13, the anti-reverse mounting structure 13 is connected with the shell 10, the anti-reverse mounting structure 13 is internally provided with a first clamping groove 133 and a second clamping groove 134 which are communicated, and the second clamping groove 134 is arranged on one side of the first clamping groove 133 facing the negative electrode conductor 30; the first clamping groove 133 is used for accommodating the positive electrode conductor 20, the positive electrode conductor 20 is clamped in the first clamping groove 133, and the second clamping groove 134 is used for accommodating the positive electrode of the battery, so that the opening of the second clamping groove 134 faces the negative electrode conductor 30, and the positive electrode of the battery can enter the second clamping groove 134 through the opening when the battery is installed.

In this embodiment, one end of the positive electrode conductor 20 is clamped in the first clamping groove 133, and the other end of the positive electrode conductor 20 contacting the battery can be accommodated in the first clamping groove 133 or extend into the second clamping groove 134.

It can be understood that, since the positive electrode of the battery is a convex hull protruding from the battery, and the negative electrode of the battery is a plane, and the diameter of the convex hull is smaller than that of the battery, the convex hull of the battery can enter the second clamping groove 134 when the battery is assembled; in some embodiments, the convex hull of the battery abuts against the positive electrode conductor 20 in the second clamping groove 134, and at this time, the end of the positive electrode conductor 20 contacting the battery extends into the second clamping groove 134; in other embodiments, the convex hull of the battery passes through the second clamping groove 134 and abuts against the positive electrode conductor 20 in the first clamping groove 133, and at this time, the end of the positive electrode conductor 20 contacting the battery is accommodated in the first clamping groove 133.

In this embodiment, the positive electrode conductor 20 is clamped in the anti-reverse mounting structure 13, so that the negative electrode of the battery cannot contact with the positive electrode conductor 20, when the battery is mounted in the housing 10, the convex hull can enter the anti-reverse mounting structure 13 and contact with the positive electrode conductor 20, and if the battery is reversely mounted, the negative electrode of the battery cannot enter the anti-reverse mounting structure 13; that is, in the present embodiment, the anti-reverse mounting structure 13 functions to restrict the displacement of the battery in addition to the positive electrode conductor 20 so that only the convex hull of the battery can enter the anti-reverse mounting structure 13.

It will be appreciated that to achieve the effect that only the convex hull of the battery can enter the second slot 134 and the negative electrode of the battery cannot enter the second slot 134, the width of the second slot 134 should be smaller than the diameter of the battery.

The negative conductor 30 may be bolted, snapped, glued or otherwise secured within the housing 10.

In this embodiment, the positive electrode conductor 20 is clamped in the anti-reverse mounting structure 13, so that the negative electrode of the battery cannot contact with the positive electrode conductor 20 during reverse mounting, thereby avoiding damage to the product.

Referring to fig. 1, in some embodiments, the housing 10 includes two short side walls 101 disposed at opposite intervals, two long side walls 102 disposed at opposite intervals, and a bottom wall 103, the two short side walls 101 and the two long side walls 102 are sequentially connected alternately, and the two short side walls 101 and the two long side walls 102 are connected to the bottom wall 103, and the two short side walls 101, the two long side walls 102, and the bottom wall 103 enclose an accommodating space, in which the battery, the positive electrode conductor 20, and the negative electrode conductor 30 are all accommodated.

Referring to fig. 2, the extending direction of the short side wall 101 is the width direction of the casing 10, i.e. the direction of the Y axis in the drawing, the extending direction of the long side wall 102 is the length direction of the casing 10, i.e. the direction of the X axis in the drawing, and the length direction of the casing 10 is parallel to the axial direction of the battery, so that the positive electrode conductor 20 and the negative electrode conductor 30 are relatively spaced in the casing 10 along the length direction of the casing 10 for saving space.

The Z-axis is shown as being in the height direction of the housing 10.

Referring to fig. 1 and 10, in an embodiment, the anti-reverse mounting structure 13 includes two opposite clamping columns 132 disposed at intervals, and a first clamping groove 133 is formed between the two clamping columns 132 and the inner surface of the housing 10, that is, the positive electrode conductor 20 is clamped between the two clamping columns 132 and abuts against the inner surface of the housing 10; the second clamping groove 134 is formed between the two clamping columns 132, that is, the positive electrode of the battery can be abutted against the positive electrode conductor 20 between the two clamping columns 132.

The width of the first clamping groove 133 is greater than that of the second clamping groove 134, so that one end of the positive electrode conductor 20 can be clamped in the first clamping groove 133.

In some embodiments, the anti-reverse structure 13 and the negative electrode conductor 30 are provided on the two short side walls 101, respectively, so as to enable the positive electrode conductor 20 and the negative electrode conductor 30 to be disposed at intervals in the axial direction of the battery.

Because the convex hull of the battery is contacted with the positive electrode conductor 20 along the axial direction of the battery, the positive electrode conductor 20 cannot extend to the outside of the anti-reverse-mounting structure 13 along the axial direction of the battery, so that the contact between the negative electrode of the battery and the positive electrode conductor 20 during reverse mounting of the battery is avoided, and the damage to products caused by reverse mounting of the battery is avoided.

It will be appreciated that, to ensure stable connection between the battery and the positive electrode conductor 20, after the battery is installed in the housing 10, the convex hull enters the anti-reverse-installation structure 13 and abuts against the positive electrode conductor 20, and if the positive electrode conductor 20 is an elastic member, the convex hull will also deform the positive electrode conductor 20 under compression.

In some embodiments, the card post 132 further includes a first sidewall 1321 facing the short side sidewall 101 and a second sidewall 1322 connected to the first sidewall 1321, where the first sidewall 1321 is disposed opposite to the short side sidewall 101, and the second sidewall 1322 is connected to the first sidewall 1321 and also connected to the short side sidewall 101.

Further, the clamping post 132 is an L-shaped member disposed on the short side wall 101, the L-shaped member extends along the height direction of the housing 10 and cooperates with the short side wall 101 to form the anti-reverse mounting structure 13, the minimum distance between the two L-shaped members is the distance between the two first side walls 1321, and the distance between the two first side walls 1321 is smaller than the diameter of the battery, so that the vicinity of the battery cannot enter between the two L-shaped members; the distance between the two first sidewalls 1321 is greater than the diameter of the convex hull so that the convex hull of the battery can enter the anti-reverse structure 13 through between the two first sidewalls 1321.

The positive electrode conductor 20 can be inserted into the anti-reverse structure 13 in the height direction of the case 10.

In some embodiments, the anti-reverse mounting structure 13 is provided with a positive electrode buckle 15 connected to the housing 10, the positive electrode buckle 15 abuts against the positive electrode conductor 20 along the extending direction of the clamping post 132, the extending direction of the clamping post 132 is the height direction of the housing 10, the positive electrode buckle 15 can enable one side of the positive electrode conductor 20 away from the positive electrode buckle 15 to abut against the bottom wall 103, and the positive electrode buckle 15 has the function of limiting the displacement of the positive electrode conductor 20, so that the positive electrode conductor 20 is prevented from shaking and falling out from the anti-reverse mounting structure 13; because the anti-reverse mounting structure 13 extends along the height direction of the housing 10, the positive electrode buckle 15 is specifically disposed on one side of the anti-reverse mounting structure 13 away from the bottom wall 103, and the positive electrode buckle 15 may be a bump protruding from the short side wall 101, or may be a boss or other structure.

One end of the negative electrode conductor 30 is clamped in the negative electrode clamping groove 14, and the other end of the negative electrode conductor 30 extends into the shell 10, namely, the negative electrode conductor 30 can be contacted with the negative electrode of the battery when the battery is arranged in the battery bin 100; in the present embodiment, the negative electrode clamping groove 14 is used for fixing the negative electrode conductor 30.

In some embodiments, the negative electrode clamping groove 14 is provided on the short side wall 101 so as to fix the negative electrode conductor 30 on the short side wall 101, so that the positive electrode conductor 20 and the negative electrode conductor 30 can be arranged at intervals along the axial direction of the battery.

In some embodiments, the negative card slot 14 also includes two oppositely spaced L-shaped members.

In some embodiments, the negative notch 16 formed in the casing 10 is disposed beside the negative slot 14, and one end of the negative conductor 30 can pass through the negative notch 16 and extend out of the casing 10, specifically, one end of the negative conductor 30 facing away from the battery can extend out of the casing 10, and the end can be connected to an external electrical component, and can also be connected to the external circuit board 60 or other components.

The cross section of the guide groove 111 may be arc-shaped, square or other shapes, and since the battery needs to be clamped in the guide groove 111 when being loaded into the battery compartment 100, the guide groove 111 has an opening to facilitate the clamping of the battery, and the bottom surface of the guide groove 111 is the inner wall surface of the guide groove 111 opposite to the opening.

It can be appreciated that, since the battery compartment 100 is only used for accommodating batteries of a predetermined specification, and the batteries are standard components and have corresponding dimension standards, the dimension of the guide groove 111 can be set according to the battery model corresponding to the battery compartment 100.
