[0007] A support frame is used to support lithium batteries; and the length direction of the support frame is defined as the left-right direction, and the width direction is defined as the front-back direction.

[0008] A battery placement slot is installed on the upper end of the support frame, which can accommodate the lower end of the lithium battery and restrict the movement of the lithium battery in the front-back and left-right directions.

[0009] A battery locking plate is provided, which contacts the upper end of the lithium battery and is connected to the support frame via a stud assembly to restrict the vertical movement of the lithium battery. The battery locking plate is made of 65Mn material.

[0010] Furthermore, the limiting groove includes four limiting plates, which together form a rectangular battery placement groove.

[0011] Furthermore, the cross-section of the limiting plate is L-shaped.

[0012] Furthermore, it also includes a separator disposed within the battery placement slot, the separator dividing the battery placement slot into two receiving slots, each of which can accommodate the lower end of a lithium battery.

[0013] Furthermore, the bolt assembly is provided in three sets, with the three sets of bolt assemblies located at both ends and the middle of the battery placement slot, respectively.

[0014] Furthermore, the battery locking plate is provided with connecting lugs corresponding to the positions of the bolt assembly.

[0015] Furthermore, the bolt assembly includes a stud, the two ends of which are connected to the support frame and the battery locking plate respectively by fasteners.

[0016] Furthermore, the contact surfaces of the battery placement slot and the battery locking plate with the lithium battery are both provided with cushioning rubber pads.

[0017] Furthermore, the bottom of the support frame is provided with several mounting feet.

[0018] The beneficial technical effects of this utility model are:

[0019] During use, the lithium battery is placed in the battery placement slot, which limits its forward and backward, and left and right movements. The battery locking plate then locks the top of the battery in place, and the locking plate is connected to the support frame via studs, thus securing the lithium battery. The inclusion of cushioning rubber pads further enhances the safety of the battery's secure fastening. The entire fixing structure does not damage the lithium battery's structure, is easy to install and disassemble, and is compatible with different types of lithium batteries, improving the convenience and safety of using new energy vehicles.

The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] This specific embodiment discloses in detail a fixing structure for a lithium battery, such as... Figures 1 to 3 As shown, it includes:

[0031] The support frame 1 is used to support the lithium battery 5; and the length direction of the support frame is defined as the left-right direction, and the width direction is defined as the front-back direction.

[0032] Battery placement slot 2 is installed on the upper end of the support frame, which can accommodate the lower end of the lithium battery and restrict the movement of the lithium battery in the front-back and left-right directions.

[0033] The battery locking plate 3 contacts the upper end of the lithium battery and is connected to the support frame via the stud assembly 4 to restrict the vertical movement of the lithium battery. The battery locking plate is made of 65Mn, which has strong toughness and elasticity, and can reduce the shaking of the battery in equipment or vehicles on vibrating and bumpy road sections.
