[0024] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the invention, and are not intended to limit the scope of the invention.

[0025] In this specification, when describing the structural position of each component, directional expressions such as "upper", "lower", "left", "right", "top", "bottom" are not absolute but relative. When the components are arranged as shown in the figure, these directional expressions are appropriate, but when the position of the components in the figure changes, these directional expressions should also change accordingly.

[0026] In addition, the X direction represents the longitudinal direction of the vehicle (ie, the driving direction of the vehicle), the Y direction represents the lateral direction of the vehicle (ie, the direction forming a 90-degree angle with respect to the driving direction), and the Z direction represents the vertical direction of the vehicle (ie, the up and down direction).

[0027] Below with the help of Figures 1 to 6b To describe a preferred embodiment of the present invention. In order to show the structure clearly, Figures 3 to 5 The blocked parts are shown with dotted lines.

[0028] like Figure 1 , Figure 2 and Figure 6a As shown, the vehicle V is, for example, an electric vehicle or a hybrid vehicle, and a battery pack E is arranged at the bottom thereof, and a battery assembly 100 is arranged in the battery pack E. The battery assembly 100 includes a support frame 3, a battery module 10 assembled to the support frame 3, and a positioning member 2 arranged between the battery module 10 and the support frame 3. More specifically, the battery module 10 is composed of a battery cell (not shown) and a battery housing 1 that wraps the battery cell, and the support frame 3 is located below the left and right side plates 13 (also called end plates) of the battery housing 1 along the Z direction. A mounting hole 31 is provided on the support frame 3, and a cylindrical limiting groove 11 extending along the Z direction is provided in the two side plates 13 of the battery housing 1.

[0029] like Figure 2 As shown, multiple battery modules 10 can be arranged horizontally along the X or Y direction, or can be stacked up and down along the Z direction. When two battery modules 10 are stacked up and down along the Z direction, the support frame 3 is arranged below the left and right side plates 13 of the upper battery module 10.

[0030] The positioning member 2 includes a connecting portion 21 and a guide portion 22 extending from the connecting portion 21. The connecting portion 21 is fixed to the mounting hole 31 of the support frame 3, and the guide portion 22 is assembled into the limiting groove 11 of the battery housing 1, so as to position the battery housing 1 on the support frame 3 to prevent it from moving left and right. It can be understood that the number and position of the positioning members 2 are determined according to actual needs, and the present invention does not limit this. For example, a positioning member 2 can be set in the middle position of the connection area between the left and right side plates 13 of the battery housing 1 and the support frame 3.

[0031] like Figures 3 to 5 As shown, preferably, the guide portion 22 is coaxially arranged with the connecting portion 21 (i.e., has the same central axis 4). According to an embodiment, the positioning member 2 can also be arranged in a non-axisymmetric shape, which is not limited by the present invention. The connecting portion 21 and the guide portion 22 are preferably integrally formed.

[0032] like Figure 4 and Figure 5 As shown, the connection portion 21 includes a connection column 211 and a plurality of ridges 213 radially protruding outward from the surface of the connection column 211, and the ridges 213 are preferably parallel to the central axis 4 (i.e., the central axis of the connection column 211) and extend to the free end surface 215 of the connection portion 21. In addition, the free end surface 215 of the connection portion 21 is preferably provided with a circular chamfer 212. The provision of the circular chamfer 212 can facilitate the connection portion 21 to be inserted and fixed to the mounting hole 31.

[0033] In fact, the connection column 211 and the ridge 213 are arranged to form a riveted connection between the positioning member 2 and the support frame 3. More specifically, the radial dimension of the mounting hole 31 is matched with the radial dimension D of the connection column 211, the connection portion 21 is squeezed into the mounting hole 31 by pressure, and the inner wall of the mounting hole 31 is plastically deformed due to the presence of the ridge 213, thereby producing a locking effect.

[0034] like Figure 4 and Figure 6a As shown, a side of the guide portion 22 close to the connecting portion 21 is provided with an abutting surface 221 abutting against the upper surface 32 of the support frame 3, and the radial dimension D1 of the abutting surface 221 is greater than the radial dimension D of the connecting column 211. In addition, the guide portion 22 has a guide surface 222, which is configured to guide the battery housing 1 to be positioned to the support frame 3 and provide an escape space for the tilting movement of the battery housing 1 relative to the central axis 4 when the battery housing 1 is disassembled. The guide surface 222 is arranged to be inclined relative to the inner wall 111 of the limiting groove 11 to guide the guide portion 22 to enter the limiting groove 11, and the guide portion 22 is formed into a cone or a frustum shape, for example.

[0035] like Figure 6a and Figure 6bAs shown, when the battery housing 1 needs to be installed on the support frame 3, first insert and fix the connecting column 211 of the positioning member 2 into the mounting hole 31, and then move the lower edge 12 of the battery housing 1 along the guide surface 222 to a preset position, that is, the moving path of the lower edge 12 of the battery housing 1 coincides with the guide surface 222, and the guide surface 222 guides the guide portion 22 to enter the limiting groove 11 of the battery housing 1, and makes the abutting surface 221 abut against the support frame 3; when the battery housing 1 needs to be disassembled from the support frame 3, insert a lever 5 under the lower edge 12 of the battery housing 1, pry the lever 5 to tilt the battery housing 1 toward the guide surface 222, and then take it out upward. Compared with the method of taking out the battery housing 1 vertically upward, this can reduce the force used for disassembly and facilitate operation.

[0036] Preferably, the free end surface 223 of the guide portion 22 is provided with an inwardly recessed cavity 23. The provision of the cavity 23 is due to the requirements of the equipment tooling on the one hand, and can reduce the overall mass of the positioning member 2 on the other hand.

[0037] The material of the positioning member 2 is preferably stainless steel. According to other embodiments, the positioning member 2 may also be made of other materials, such as aluminum, high-strength alloy, etc., which is not limited in the present invention.

[0038] In addition, a connecting section 214 is provided between the guide portion 22 and the connecting portion 21 . The radial dimension D2 of the connecting section 214 is smaller than the radial dimension D of the connecting column 211 , and serves as a transition between the guide portion 22 and the connecting portion 21 .

[0039] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative ideas of the present invention, technicians in this field can make various changes and improvements to the above-disclosed concepts, but all belong to the protection scope of the present invention.

[0040] The description of the above embodiments is intended to be illustrative rather than restrictive. The protection scope of the present invention is determined by the claims.
