It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0045] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0046] Embodiment 1

[0047] The embodiment of the utility model provides a battery module, which can effectively improve the installation stability of the battery and prevent the battery from being separated or falling off.

[0048] See also Figures 1 to 13 The battery module includes an insulating base 1, a first elastic lead-out row 2 and a second elastic lead-out row 3; the insulating base 1 is used to support and insulate and separate the first elastic lead-out row 2 and the second elastic lead-out row 3.

[0049] The first elastic lead-out row 2 and the second elastic lead-out row 3 are arranged on the insulating base 1 opposite to each other, and a mounting groove 100 for mounting a battery is formed between the first elastic lead-out row 2 and the second elastic lead-out row 3 .

[0050] The first elastic lead-out row 2 is provided with a first abutting conductive portion 21 for abutting against one end of the battery, and the first elastic lead-out row 2 is bent and extended to form a first pressing portion 22 for elastically pressing one end of the battery into the mounting groove 100. The second elastic lead-out row 3 is provided with a second abutting conductive portion 31 for abutting against the other end of the battery, and the second elastic lead-out row 3 is bent and extended to form a second pressing portion 32 for elastically pressing the other end of the battery into the mounting groove 100.

[0051] In this embodiment, when the battery is installed in the mounting groove 100 between the first elastic lead-out row 2 and the second elastic lead-out row 3, the two poles of the battery respectively contact and conduct the first abutting conductive part 21 and the second abutting conductive part 31, and the two ends of the battery are elastically pressed in the mounting groove 100 by the first clamping part 22 and the second clamping part 32, respectively, thereby effectively reducing the possibility of the battery detaching from the mounting groove 100 due to vibration and the like. The structure in this embodiment effectively improves the installation stability of the battery. It should be noted that the battery in this embodiment is a cylindrical battery, which can be a cylindrical battery, a rectangular battery or a cylindrical battery of other shapes. It should also be noted that the first elastic lead-out row 2 is integrally formed and made of conductive metal; similarly, the second elastic lead-out row 3 is integrally formed and made of conductive metal.

[0052] Optionally, an opening 101 for allowing the battery to enter the mounting groove 100 is formed between the first pressing portion 22 and the second pressing portion 32; the first pressing portion 22 can be elastically bent in a direction away from the second pressing portion 32, and the second pressing portion 32 can be elastically bent in a direction away from the first pressing portion 22. That is, the battery is pressed into the mounting groove 100 from the opening, and in the process of the battery being pressed into the mounting groove 100, the first pressing portion 22 is elastically bent in a direction away from the second pressing portion 32 and / or the second pressing portion 32 is elastically bent in a direction away from the first pressing portion 22. In the structure of this embodiment, the first pressing portion 22 and the second pressing portion 32 are equivalent to being located on the notch side of the mounting groove 100 to prevent the battery from falling out. When disassembling and assembling the battery, the positions of the first pressing portion 22 and the second pressing portion 32 can be changed accordingly, that is, the disassembly and assembly of the battery can be completed quickly, making the disassembly and assembly of the battery more convenient.

[0053] Optionally, a first limiting groove 201 is provided on the first pressing portion 22, and a second limiting groove 301 is provided on the second pressing portion 32; when the battery is installed in the mounting groove 100, one end of the battery is embedded in the first limiting groove 201, and the other end of the battery is embedded in the second limiting groove 301. Specifically, one end of the battery is limited by the first limiting groove 201, and the other end of the battery is limited by the second limiting groove 301, so that the workpiece is more accurately installed in the mounting groove 100, the installation accuracy of the battery is improved, and the battery can be further prevented from falling off.

[0054] Optionally, the first abutting conductive part 21 is a convex structure, and the second abutting conductive part 31 is a spring-shaped structure; the convex structure bulges toward the direction close to the battery, and the spring-shaped structure bulges toward the direction close to the battery. Specifically, the first abutting conductive part 21 and the second abutting conductive part 31 have different structures, which obviously has a foolproof effect when cooperating with the first limiting groove 201 and the second limiting groove 301, and effectively prevents the battery from being installed upside down. Figure 8 and Fig.11The abutting surface of the second abutting conductive part 31 is flush with the bottom of the second limiting groove 301, while the abutting surface of the first abutting conductive part 21 and the bottom of the first limiting groove 201 are obviously not flush. Therefore, when the battery is installed upside down, it can be clearly seen that the state of the first clamping part 22 and the second clamping part 32 is obviously different from the state when the battery is normally installed, that is, the battery module has a good anti-foolproof effect.

[0055] Optionally, a plurality of first elastic lead-out rows 2 and second elastic lead-out rows 3 corresponding to the plurality of first elastic lead-out rows 2 are arranged on the insulating base 1; two adjacent first elastic lead-out rows 2 are conductively connected, and two adjacent second elastic lead-out rows 3 are conductively connected to connect the batteries in parallel, thereby realizing the need to install a row of batteries, that is, meeting the need to install more batteries.

[0056] Optionally, the battery module also includes a flexible circuit board 4 installed on the insulating base 1; the first elastic lead-out row 2 is provided with a first lead-out portion 202, and two adjacent first elastic lead-out rows 2 are connected in parallel by overlapping a first lead-out portion 202, and a first extension connection portion 203 is extended on the first lead-out portion 202 of the first elastic lead-out row 2 at one end of the same row, and the first extension connection portion 203 is connected to an output copper bus, and each first elastic lead-out row 2 is connected to the flexible circuit board 4 through a side connecting strip; the second elastic lead-out row 3 is provided with a second lead-out portion 302, and two adjacent second elastic lead-out rows 3 are connected in parallel by overlapping a second lead-out portion 302, and a second extension connection portion 303 for connecting another output copper bus is extended on the second lead-out portion 302 of the second elastic lead-out row 3 at the other end of the same row. It should also be noted that the raised portion at one end of the battery cell is the first pole, which is in contact with the second abutting conductive portion 31 for conduction; the other end and the outer peripheral side of the battery cell form the second pole, which is in contact with the first elastic lead-out row 2, and the abutment area between the second pole and the first elastic lead-out row 2 is larger, which improves the conduction effect. It should also be noted that the insulating base 1 insulates and separates the first elastic lead-out row 2 and the second elastic lead-out row 3, and the groove wall of the second arc groove 33 and the outer peripheral wall of the battery are previously insulated and separated by the insulating base 1.

[0057] It is also necessary to add that two adjacent first elastic lead-out rows 2 are connected through a first lead-out portion 202, that is, the first lead-out portion 202 on the rear first elastic lead-out row 2 is overlapped on the front first elastic lead-out row 2, thereby realizing the parallel connection of the two adjacent first elastic lead-out rows 2, and the first lead-out portion 202 is curved, which provides a larger fitting connection area for the overlap and does not affect the installation of the battery. Similarly, two adjacent second elastic lead-out rows 3 are fitted and overlapped through the arc-shaped second lead-out portion 302. In addition, the first extended connection portion 203 on the first elastic lead-out row 2 at the end is connected to the output copper bar, and the second extended connection portion 303 extended from the second lead-out portion 302 on the second elastic lead-out row 3 at the other end of the copper bar is connected to the flexible circuit board 4, and the flexible circuit board 4 is respectively connected to each first elastic lead-out row 2 through a connecting strip, so that the temperature, voltage and other information of the battery can be detected to meet the needs of battery management.

[0058] Optionally, the first extending connection portion 203 extends out of the insulating base 1 , and the second extending connection portion 303 extends out of the insulating base 1 , so as to facilitate connection and further reduce the difficulty of installation.
