Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a flame-retardant component, a battery, and an electric two-wheeler. Background Technology

[0002] Some batteries are equipped with thermal aerosol fire extinguishers. When the temperature inside the battery becomes too high and a fire is possible, the thermal aerosol fire extinguisher senses the fire and sprays an aerosol to extinguish it. In existing technology, because the space between the battery cell module and the cover is relatively large, thermal aerosol fire extinguishers are generally installed between the cell module and the battery cover. However, other areas, such as the space between the side wall of the cell module and the side wall of the casing, have smaller spaces, making it difficult to install thermal aerosol fire extinguishers. This results in difficulty in extinguishing fires in other easily flammable areas inside the battery, making it impractical. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a flame-retardant component that facilitates the installation of a thermal aerosol fire extinguisher in the desired location around the battery cell module, thereby achieving better flame-retardant and fire-extinguishing effects.

[0004] This utility model also proposes a battery having the above-mentioned flame-retardant components.

The mounting cylinder has a first end and a second end opposite to each other along the axial direction. The first end is closed, and the second end has an opening. The edge of the second end has an annular flange. The mounting cylinder is used to pass through the mounting hole so that the first end extends out of the housing and the second end is located inside the housing. The annular flange is used to connect the housing. The thermal aerosol fire extinguisher is disposed inside the mounting cylinder and has a spray end that extends out of the opening.

[0007] The flame-retardant component according to the embodiments of this utility model has at least the following beneficial effects:

[0008] To install a thermal aerosol fire extinguisher in a desired location around a battery cell module, such as on one side of the cell module, mounting holes can be made in the side wall of the battery casing. The mounting cylinder containing the thermal aerosol fire extinguisher is then inserted through the mounting hole, with the first end of the cylinder extending out of the casing and the second end inside. Finally, the annular flange of the mounting cylinder is connected to the side wall of the casing.

[0041] The following is for reference. Figures 1 to 3 This invention describes a flame-retardant component, a battery, and an electric two-wheeler according to embodiments of the present invention.

[0042] According to the first aspect of the present invention, the flame-retardant component, such as Figures 1 to 3As shown, a housing 600 for mounting batteries is provided. The housing 600 is provided with mounting holes 601. For example, the mounting holes 601 may be provided on the side wall or bottom plate of the housing 600. The number of mounting holes 601 may be one or more. The position of the mounting holes 601 is determined according to actual needs. The flame retardant components include a mounting cylinder 100 and a thermal aerosol fire extinguisher 200.

[0043] The mounting cylinder 100 has a first end 101 and a second end 102 along the axial direction. The first end 101 is closed, and the second end 102 has an opening 103. The edge of the second end 102 has an annular flange 104, which surrounds the mounting cylinder 100. The mounting cylinder 100 is used to pass through the mounting hole 601 so that the first end 101 extends out of the housing 600 and the second end 102 is located inside the housing 600. The annular flange 104 is used to connect the housing 600. The thermal aerosol fire extinguisher 200 is disposed inside the mounting cylinder 100. The thermal aerosol fire extinguisher 200 has a spray end 201 that extends out of the opening 103.

[0044] The thermal aerosol fire extinguisher 200 needs to be installed in the required position around the battery cell module, such as on one side of the cell module. A mounting hole 601 can be made on the side wall of the battery housing 600. Then, the mounting cylinder 100 with the thermal aerosol fire extinguisher 200 installed is inserted through the mounting hole 601, so that the first end 101 of the mounting cylinder 100 extends out of the housing 600 and the second end 102 is located inside the housing 600. Finally, the annular flange 104 of the mounting cylinder 100 is connected to the side wall of the housing 600. Since the spray end 201 of the thermal aerosol fire extinguisher 200 extends out of the opening 103, that is, located between the cell module and the side wall of the housing 600, it can perform flame-retardant fire extinguishing work.

[0045] In this invention, after the flame-retardant components are installed, the first end 101 of the mounting cylinder 100 extends out of the housing 600, and most of the thermal aerosol fire extinguisher 200 located inside the mounting cylinder 100 also extends out of the housing 600. This avoids the situation where the thermal aerosol fire extinguisher 200 is difficult to install due to insufficient installation space, and makes it easier to install the thermal aerosol fire extinguisher 200 in the required position around the battery cell module, resulting in a better flame-retardant and fire-extinguishing effect.

[0046] refer to Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the spray end 201 is provided with a nozzle 202, and the flame retardant component also includes a mounting bracket 300. The mounting bracket 300 is rotatably mounted inside the mounting cylinder 100 around the axis of the mounting cylinder 100, and the thermal aerosol fire extinguisher 200 is mounted on the mounting bracket 300. When the mounting bracket 300 rotates, the spray direction of the nozzle 202 can be directed toward different positions of the axis of the mounting cylinder 100.

[0047] In this embodiment, by rotating and adjusting the mounting bracket 300, the spray direction of the nozzle 202 of the thermal aerosol fire extinguisher 200 can be directed toward different positions of the axis of the mounting cylinder 100. By rotating and adjusting the mounting bracket 300, the thermal aerosol fire extinguisher 200 can accurately spray aerosol toward areas prone to fire, resulting in a better flame-retardant fire extinguishing effect.

[0048] refer to Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the inner circumferential wall of the mounting cylinder 100 is provided with an internal thread, and the mounting bracket 300 is provided with an external thread. The mounting bracket 300 is connected to the mounting cylinder 100 by the mating of the external thread and the internal thread, so that it can move along the axial direction of the mounting cylinder 100 when the mounting bracket 300 rotates.

[0049] In this embodiment, the mounting bracket 300 is connected to the mounting cylinder 100 by a mating external thread and an internal thread. This allows the mounting bracket 300 to rotate around the axis of the mounting cylinder 100. Furthermore, when the mounting bracket 300 rotates, it can also move and adjust along the axial direction of the mounting cylinder 100. This allows the size of the thermal aerosol fire extinguisher 200 extending out of the mounting cylinder 100 to be adjusted according to actual needs, making it more convenient and accurate for the thermal aerosol fire extinguisher 200 to spray aerosol.

[0050] refer to Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the thermal aerosol fire extinguisher 200 can be rotated and adjusted relative to the mounting bracket 300, and the rotation axis of the thermal aerosol fire extinguisher 200 is perpendicular to the rotation axis of the mounting bracket 300.

[0051] In this embodiment, in addition to the mounting bracket 300 rotating around the axis of the mounting cylinder 100, thereby allowing the nozzle 202 of the thermal aerosol fire extinguisher 200 to spray in different directions relative to the axis of the mounting cylinder 100, the thermal aerosol fire extinguisher 200 can also rotate at a certain angle relative to the mounting bracket 300, thereby causing the nozzle 202 of the thermal aerosol fire extinguisher 200 to deflect at a certain angle relative to the axis of the mounting cylinder 100. In this way, the thermal aerosol fire extinguisher 200 can spray aerosol more conveniently and accurately.

[0052] refer to Figure 2 and Figure 3As shown, in some embodiments of this utility model, the mounting bracket 300 is provided with a first hinge portion 301 and a second hinge portion 302. The thermal aerosol fire extinguisher 200 is hinged to the first hinge portion 301, and an adjusting rod 303 is hinged to the second hinge portion 302. The thermal aerosol fire extinguisher 200 and the adjusting rod 303 are connected by a first fastener 304, and the first fastener 304 can be adjusted in position along the length direction of the adjusting rod 303. For example, the hinge axis between the thermal aerosol fire extinguisher 200 and the first hinge portion 301, and the hinge axis between the adjusting rod 303 and the second hinge portion 302, can both be parallel to the axial direction of the first fastener 304 and perpendicular to the axis of the mounting cylinder 100.

[0053] In this embodiment, by adjusting the position of the first fastener 304 along the length of the adjusting rod 303, the thermal aerosol fire extinguisher 200 can rotate at a certain angle relative to the mounting bracket 300, thereby causing the spray direction of the nozzle 202 of the thermal aerosol fire extinguisher 200 to rotate at a certain angle relative to the axis of the mounting cylinder 100. The structure is simple and the operation is convenient.

[0054] refer to Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the adjusting rod 303 is provided with an adjusting groove 305, the adjusting groove 305 extends along the length direction of the adjusting rod 303, and the first fastener 304 passes through the adjusting groove 305 and can be located at different positions along the length direction of the adjusting groove 305.

[0055] In this embodiment, when the thermal aerosol fire extinguisher 200 needs to be rotated and adjusted, the first fastener 304 is loosened, and then the first fastener 304 is slid along the length of the adjustment groove 305 to the desired position. After that, the first fastener 304 is tightened. The structure is simple and the operation is convenient.

[0056] It should be noted that the first fastener 304 can also be adjusted in position along the length of the adjusting rod 303 in other ways. For example, the adjusting rod 303 can be provided with multiple connecting holes, which can be arranged along the length of the adjusting rod 303. The first fastener 304 can be inserted into different mounting holes 601.

[0057] refer to Figure 2 and Figure 3 As shown, in some embodiments of this invention, the annular flange 104 is connected to the housing 600 via a second fastener 400. This makes the installation and removal of the flame-retardant components more convenient.

[0058] It should be noted that the annular flange 104 can also be welded to the housing 600.

[0059] refer to Figure 2 and Figure 3As shown, in some embodiments of this utility model, the flame-retardant component further includes an annular sealing gasket 500, which is sleeved on the outside of the mounting cylinder 100 and clamped between the annular flange 104 and the inner surface of the housing 600.

[0060] In this embodiment, an annular sealing gasket 500 is provided to improve the sealing performance at the connection between the flame-retardant component and the housing 600, thereby improving the sealing performance of the battery.

[0061] The battery according to a second aspect embodiment of the present invention includes the flame-retardant component described in the first aspect embodiment. For example, the battery may further include a housing 600, the flame-retardant component being mounted on the housing 600, and a cover being provided at the top of the housing 600.

[0062] The battery adopts the flame-retardant components of the first aspect of this utility model, which makes it convenient to install the thermal aerosol fire extinguisher 200 in the required position around the battery cell module, thereby improving the flame-retardant and fire-extinguishing effect.

[0063] It should be noted that since the battery can adopt all the technical solutions of the flame-retardant components of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment.
