[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0036] Please refer to Figures 1 to 8 The embodiment of the utility model discloses a battery, and the disclosed battery includes a battery body 100, a circuit board 200, and a plastic sealing part 300.

[0037] The first end of the battery body 100 has a tab 110 , and the tab 110 is used to electrically connect the battery body 100 to other parts of the battery.

[0038] The circuit board 200 is disposed on the tab 110 and is electrically connected to the tab 110. The circuit board 200 is electrically connected to the battery body 100 through the tab 110. Specifically, the circuit board 200 may have an electrical connection portion, and the circuit board 200 may be electrically connected to the tab 110 through the electrical connection portion, and the material of the electrical connection portion may be nickel or other conductive materials.

[0039] The plastic sealing part 300 covers the tab 110 and the circuit board 200, and is provided with heat dissipation holes 301, the openings of which can be exposed on the outer surface of the plastic sealing part 300. The plastic sealing part 300 can be formed by injection molding in an injection molding machine.

[0040] It should be noted that when the battery is outputting power, the electronic devices on the circuit board 200 will generate heat, and the heat generated by the electronic devices will be dissipated through the plastic sealing part 300. The plastic sealing part 300 is provided with heat dissipation holes 301, so that the area of ​​the outer surface of the plastic sealing part 300 for heat exchange with the environment can be increased. After the heat generated by the electronic devices on the circuit board 200 passes through the plastic sealing part 300, the heat is exchanged with the external environment through the outer surface of the plastic sealing part 300, so as to transfer the heat generated by the electronic devices on the circuit board 200 to the external environment, thereby achieving heat dissipation of the circuit board 200.

[0041] The battery disclosed in the embodiment of the present application electrically connects the circuit board 200 with the pole ear 110, so that the circuit board 200 is electrically connected to the battery body 100 through the pole ear 110, and covers the pole ear 110 and the circuit board 200 with the plastic sealing part 300, so that the plastic sealing part 300 can fix and protect the pole ear 110 and the circuit board 200, and by opening the heat dissipation hole 301 in the plastic sealing part 300, the heat dissipation area of ​​the plastic sealing part 300 can be increased, which is beneficial to improving the heat dissipation capacity of the circuit board 200, and further can solve the problem of affecting the service life of the battery due to the excessive temperature of the circuit board 200, and even causing battery damage.

[0042] Specifically, the plastic sealing part 300 can be injection molded with a polyamide material, and of course the plastic sealing part 300 can also be injection molded with other materials having insulation, waterproof, moisture-proof and other properties. The material of the plastic sealing part 300 can also be a heat-dissipating material, so that the heat of the circuit board 200 can be better distributed to improve the heat dissipation capacity of the circuit board 200.

[0043] In order to improve the heat dissipation capacity of the battery, optionally, there can be multiple heat dissipation holes 301, and the multiple heat dissipation holes 301 can be evenly distributed on the plastic sealing part 300, thereby improving the heat dissipation capacity of the battery.

By setting the heat dissipation hole 301 as a through hole, the heat dissipation capacity of the circuit board 200 can be further improved.

[0045] In an optional embodiment, the battery body 100 may have a packaging extension portion 120, and the packaging extension portion 120 may extend from the end surface of the first end of the battery body 100. The packaging extension portion 120 may be a portion of the packaging structure of the battery body 100 extending from the end surface of the first end of the battery body 100. The tab 110 may extend from the packaging extension portion 120, and the plastic sealing portion 300 may cover the tab 110, the circuit board 200 and the packaging extension portion 120.

[0046] The battery disclosed in the embodiment of the present application is provided with a packaging extension portion 120 on the end face of the first end of the battery body 100, so that the pole lug 110 extends from the packaging extension portion 120, thereby facilitating the installation of the pole lug 110. Moreover, the packaging extension portion 120 extends from the end face of the first end of the battery body 100, thereby facilitating the layout of the pole lug 110 and the circuit board 200 without increasing the thickness of the battery.

[0047] Optionally, the package extension portion 120 may include a straight section 121, and the extension plane of the straight section 121 may intersect with the end surface of the first end of the battery body 100. For example, the extension plane of the straight section 121 may be perpendicular to the end surface of the first end of the battery body 100. Of course, the extension plane of the straight section 121 and the end surface of the first end of the battery body 100 may also be at other angles, which are not specifically limited in the embodiments of the present application. The extension plane of the circuit board 200 may be parallel to the extension plane of the straight section 121.

[0048] The battery disclosed in the embodiment of the present application sets the package extension part 120 as a straight section 121, so that the structure of the package extension part 120 is relatively simple, which is conducive to simplifying the structure of the battery. By setting the extension plane of the straight section 121 to intersect with the end face of the first end of the battery body 100, the extension plane of the circuit board 200 is parallel to the extension plane of the straight section 121, so as to adapt to the layout situation that the extension plane of the circuit board 200 intersects with the end face of the first end of the battery body 100. In another embodiment, the package extension part 120 may include a straight section 121 and a curved section 122, the straight section 121 may be connected to the curved section 122, the straight section 121 may extend from the end face of the first end of the battery body 100 through the curved section 122, the straight section 121 may be spaced apart from the end face of the first end of the battery body 100, and the extension plane of the straight section 121 is parallel to the end face of the first end of the battery body 100. The circuit board 200 can be located on one side of the end surface of the straight section 121 facing away from the first end of the battery body 100, and the circuit board 200 and the straight section 121 are spaced apart. The circuit board 200 and the straight section 121 are spaced apart through the pole ear 110, and the extension plane of the circuit board 200 is parallel to the extension plane of the straight section 121.

[0049] The battery disclosed in the embodiment of the present application is configured such that the packaging extension portion 120 is configured to include a straight section 121 and a curved section 122, and the straight section 121 extends out of the end face of the first end of the battery body 100 through the curved section 122, the straight section 121 is spaced apart from the end face of the first end of the battery body 100, and an extension plane of the straight section 121 is parallel to the end face of the first end of the battery body 100, so that the circuit board 200 can be arranged on a side of the straight section 121 that is away from the end face of the first end of the battery body 100, and is spaced apart from the straight section 121, which is conducive to configuring the extension plane of the circuit board 200 to be parallel to the extension plane of the straight section 121, so as to adapt to the layout of the circuit board 200 after installation, so as to adapt to the extension plane of the circuit board 200 to be parallel to the end face of the first end of the battery body 100.

[0050] Optionally, the battery may further include a first insulating adhesive portion 400 . The first insulating adhesive portion 400 may be bonded between the straight section 121 and the circuit board 200 .

[0051] The battery disclosed in the embodiment of the present application is provided with a first insulating adhesive portion 400, and the first insulating adhesive portion 400 is bonded between the straight section 121 and the circuit board 200, so that the first insulating adhesive portion 400 can not only serve as a component for fixing the circuit board 200, but also the first insulating adhesive portion 400 can also serve as an insulating component between the circuit board 200 and the packaging extension portion 120, so that the first insulating adhesive portion 400 has two uses.

[0052] When the package extension portion 120 is configured to include a straight section 121 and a curved section 122, since the straight section 121 is bent by the curved section 122 until the extension plane of the straight section 121 is parallel to the end surface of the first end of the battery body 100, the curved section 122 has a certain force to restore the deformation, thereby easily causing the straight section 121 to warp. In order to prevent the straight section 121 from warping, the battery may further include a second insulating adhesive portion 600, which may be bonded between the straight section 121 and the end surface of the first end of the battery body 100, thereby preventing the straight section 121 from warping and also achieving insulation between the straight section 121 and the end surface of the first end of the battery body 100.

[0053] In order to facilitate the electrical connection between the battery and the external circuit, the battery may further include a flexible electrical connection portion 700, which may be connected to the tab 110 and extend out of the plastic sealing portion 300, thereby facilitating the electrical connection between the battery and the external circuit.

[0054] The battery disclosed in the present application can better achieve insulation of the second end of the battery body by bonding the third insulating bonding part 800 to the second end of the battery body.

[0055] In order to protect the battery body, the battery may optionally further include a protective film 900 . The protective film 900 may have a handle 910 .
