For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0030] The following will introduce in detail the specific structure of a battery heating component provided by the embodiment of the present invention and the corresponding technical effects brought thereby with reference to the patent drawings.

[0031] Please refer to Figures 1-3The battery heating assembly 1 provided by the embodiment of the present invention includes a mounting member 100 and a heating member 200. The mounting member 100 has a first mounting plate 110 and a second mounting plate 120 facing each other in a predetermined direction. The mounting surfaces of the first mounting plate 110 and the second mounting plate 120 are both provided with mounting grooves 160, and each mounting groove 160 is mounted with a heating member 200.

[0032] The mounting member 100 is used to be installed between two battery modules 201 spaced apart along a preset direction. The first mounting plate 110 and the second mounting plate 120 are used to abut against the two battery modules 201 respectively.

[0033] It is understood that the mounting surface of the first mounting plate 110 refers to the side of the first mounting plate 110 away from the second mounting plate 120, and the mounting surface of the second mounting plate 120 refers to the side of the second mounting plate 120 away from the first mounting plate 110. The heating element 200 installed in the mounting groove 160 is used to generate heat. When the first mounting plate 110 and the second mounting plate 120 of the mounting member 100 are respectively in contact with two battery modules 201, the heat emitted by the heating element 200 on the first mounting plate 110 is used to heat the battery module 201 in contact with the first mounting plate 110, and the heat emitted by the heating element 200 on the second mounting plate 120 is used to heat the battery module 201 in contact with the second mounting plate 120.

[0034] Since the first mounting plate 110 and the second mounting plate in this embodiment are directly in contact with the outer surface of the battery module 201, and are not bonded to the outer surface of the battery module 201 or wound around the outer surface of the battery module 201 through a heat exchange coil, it is convenient for operators to disassemble and assemble the fixing parts and the battery module 201.

[0035] It should be noted that heating the battery module 201 by liquid heat requires a coil to be wound around the battery module 201, and the liquid circulates in the coil to achieve heating of the battery module 201, which is relatively costly. The heating of the battery module 201 is achieved by means of a heating film, usually by applying a heating film on the surface of the battery or inside the battery pack to directly heat the battery. The assembly of the mounting member 100 and the heating member 200 in the battery heating assembly 1 provided in this embodiment to heat the battery module 201 is not only convenient for assembly and disassembly, but also has a low cost.

[0036] In detail, the mounting member 100 also includes a first connecting plate 130 and a second connecting plate 140. The first connecting plate 130, the first mounting plate 110, the second connecting plate 140 and the second mounting plate 120 are connected end to end in sequence. The first connecting plate 130 and the second connecting plate 140 are opposite to each other and are arranged at intervals along a first direction, and the first direction is perpendicular to the preset direction.

[0037] The mounting bracket provided in this embodiment is formed into an annular structure by a first connecting plate 130, a first mounting plate 110, a second connecting plate 140, and a second mounting plate 120 to ensure the connection strength of the entire mounting member 100. Specifically, in this embodiment, the first connecting plate 130, the first mounting plate 110, the second connecting plate 140, and the second mounting plate 120 are sequentially connected at right angles.

[0038] It can be understood that the heat generated by the heating element 200 on the first mounting plate 110 can also be transferred to the second mounting plate 120 through the first connecting plate 130 and the second connecting plate 140. Similarly, the heat generated by the heating element 200 on the second mounting plate 120 can also be transferred to the first mounting plate 110 through the first connecting plate 130 and the second connecting plate 140.

[0039] In order to avoid stress concentration at the connection between the first mounting plate 110 and the first connecting plate 130 and the connection between the second connecting plate 140, and to avoid stress concentration at the connection between the second mounting plate 120 and the first connecting plate 130 and the connection between the second connecting plate 140, both ends of the first connecting plate 130 are connected to the first mounting plate 110 and the second mounting plate 120 with arc transitions, and both ends of the second connecting plate 140 are connected to the first mounting plate 110 and the second mounting plate 120 with arc transitions.

[0040] Of course, in some other embodiments, the two ends of the first connecting plate 130 may not be connected to the first mounting plate 110 and the second mounting plate 120 with arc transitions, and the two ends of the second connecting plate 140 may also not be connected to the first mounting plate 110 and the second mounting plate 120 with arc transitions.

[0041] To improve the overall strength of the mounting member 100, the mounting member 100 further includes a reinforcing plate 150. The two sides of the reinforcing plate 150 in the preset direction are respectively connected to the first mounting plate 110 and the second mounting plate 120. Specifically, the reinforcing plate 150 is located between the first connecting plate 130 and the second connecting plate 140, and relatively evenly ensures the connection strength between the first mounting plate 110 and the second mounting plate 120. In the arrangement direction of the first connecting plate 130 and the second connecting plate 140, the reinforcing plate 150 is located in the middle of the first mounting plate 110 and the second mounting plate 120.

[0042] To ensure the strength of the overall mounting member 100, optionally, the mounting member 100 is an integral structure. Of course, in some other alternative embodiments, the first mounting plate 110, the second mounting plate 120, the first connecting plate 130, the second connecting plate 140, and the reinforcing plate 150 in the mounting member 100 may also be a detachable split structure.

[0043] The first mounting plate 110 is provided with a plurality of mounting grooves 160 at intervals along a first direction, and the second mounting plate 120 is provided with a plurality of mounting grooves 160 at intervals along the first direction. Each mounting groove 160 is installed with a heating element 200. The mounting grooves 160 extend along a second direction, and the first direction, the second direction, and a preset direction are perpendicular to each other in pairs. It should be noted that the first direction and the second direction are the length and width directions of the first mounting plate 110 and the second mounting plate 120.

[0044] Since there are a plurality of mounting grooves 160 on the first mounting plate 110, and there are also a plurality of mounting grooves 160 on the second mounting plate 120, and heating elements 200 are installed in all the plurality of mounting grooves 160, the overall heating efficiency of the battery heating assembly 1 can be improved.

[0045] Specifically, in this embodiment, the first direction is the width direction of the mounting member 100, the second direction is the length direction of the mounting member 100, the mounting grooves 160 on the first mounting plate 110 extend along the length direction, and the mounting grooves 160 on the second mounting plate 120 extend along the length direction. That is to say, the plurality of mounting grooves 160 on the first mounting plate 110 are arranged at intervals along the width direction of the first mounting plate 110, the mounting grooves 160 on the first mounting plate 110 extend along the length direction of the first mounting plate 110, the plurality of mounting grooves 160 on the second mounting plate 120 are arranged at intervals along the width direction of the second mounting plate 120, and the mounting grooves 160 on the second mounting plate 120 extend along the length direction of the second mounting plate 120, which can ensure that the heating elements 200 on the first mounting plate 110 and the second mounting plate 120 can transfer heat to the battery module 201 relatively evenly.

[0046] Of course, in some other embodiments, the first mounting plate 110 and the second mounting plate 120 can also be square plates.

[0047] In this embodiment, the number of the mounting grooves 160 on the first mounting plate 110 is the same as the number of the mounting grooves 160 on the second mounting plate 120, and the mounting grooves 160 on the first mounting plate 110 and the mounting grooves 160 on the second mounting plate 120 are arranged in one-to-one correspondence. The number of the mounting grooves 160 on the first mounting plate 110 is two, and the number of the mounting grooves 160 on the second mounting plate 120 is two.

[0048] In this embodiment, "a plurality" refers to a number of two or more. Therefore, in some other alternative embodiments, the number of the mounting grooves 160 can also be 3, 4, or more than 4.

[0049] In this embodiment, the cross-section of the mounting groove 160 in the first direction is sinusoidal, and the heating element 200 includes a heating wire, which is mounted in the mounting groove 160 and adapted to fit within the mounting groove 160. It will be appreciated that the heating wire also substantially assumes a positive wave shape after being placed within the mounting groove 160, thereby enabling relatively uniform heat transfer to the battery module 201 during heat transfer.

[0050] In detail, the mounting groove 160 is coated with a thermally conductive structural adhesive, and the heating element 200 is bonded to the mounting groove 160 through the thermally conductive structural adhesive. In detail, the heating wire is bonded to the mounting groove 160 through the thermally conductive structural adhesive. It can be understood that the heating element 200 is installed in the mounting groove 160 by bonding, which can ensure the connection strength between the heating wire and the mounting groove 160, and prevent the heating wire from easily falling out of the mounting groove 160. In addition, the thermally conductive structural adhesive also has a good heat transfer effect, thereby ensuring that the heat generated by the heating wire can be more efficiently transferred to the battery module 201.

[0051] The present embodiment further provides a battery device 2, comprising two battery modules 201 spaced apart along a predetermined direction and the aforementioned battery heating assembly 1. A mounting member 100 is positioned between the two battery modules 201, with a first mounting plate 110 and a second mounting plate 120 respectively abutting the two battery modules 201. Therefore, when the battery heating assembly 1 heats the battery modules 201, the heating wires on the first mounting plate 110 and the second mounting plate 120 directly transfer heat to the battery modules 201.

[0052] Since the mounting member 100 in this embodiment only contacts two battery modules 201 respectively, the heating wires on both sides of the mounting member 100 heat the battery modules 201, which makes it easier for operators to disassemble and assemble the battery modules 201 and the battery heating assembly 1.

[0053] It should be noted that the battery device 2 also includes a mounting frame, within which the battery modules 201 are mounted. The mounting frame includes a base plate and a surrounding plate. The surrounding plate is capable of abutting against the outer walls of two battery modules 201 spaced apart along a predetermined direction to restrict movement of the battery modules 201 within the mounting member 100. Since the installation of the mounting frame and the battery modules 201 is a common arrangement in the battery field, it will not be described in detail here. The battery device 2 provided in this embodiment can be used in ships or vehicles.

[0054] Optionally, in order to avoid a short circuit between the heating wire and the battery module, an insulating sheet may be placed between the mounting member 100 and the battery module 201 .

[0055] In summary, the embodiment of the present utility model provides a battery heating assembly 1 and a battery device 2. The battery device 2 includes the battery heating assembly 1, and the battery heating assembly 1 includes a mounting member 100 and a heating member 200. The mounting member 100 has opposite first and second mounting plates 110 and 120 in a preset direction. Mounting grooves 160 are formed on the mounting surfaces of the first mounting plate 110 and the second mounting plate 120, and each mounting groove 160 is provided with a heating member 200. Since the first mounting plate 110 and the second mounting plate in this embodiment are directly in contact with the outer surface of the battery module 201, it is convenient for the operator to disassemble and assemble the fixing member and the battery module 201.

[0056] It should be noted that, without conflict, the features in the embodiments of the present application may be combined with each other.

[0057] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
