[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figs. 1-3 As shown, this utility model proposes a power battery support and fixing structure, which includes a battery body 10, a frame unit 20 and fasteners 30. The frame unit 20 is arranged around the periphery of the battery body 10, and the frame unit 20 is connected to the battery body 10 through the fasteners 30.

[0019] The frame unit 20 includes a first pipe 21, a second pipe 22, a third pipe 23, and a fourth pipe 24. The first pipe 21, the second pipe 22, the third pipe 23, and the fourth pipe 24 are welded together in sequence and together form a rectangular frame.

[0020] Support seats 11 are respectively provided on the side wall of the battery body 10, and fasteners 30 are provided on the support seats 11. The first pipe 21, the second pipe 22, the third pipe 23 and the fourth pipe 24 are respectively connected to the support seats 11 on the side wall of the corresponding battery body 10 by the fasteners 30.

[0021] The first fitting 21, the second fitting 22, the third fitting 23, and the fourth fitting 24 are all square tubes with a hollow interior.

[0022] An electrical connection port is provided on one of the side walls of the battery body 10, and a support 11 on the side wall where the electrical connection port is provided is connected to the first tube 21.

[0023] The two ends of the first pipe fitting 21 are connected to the second pipe fitting 22 and the fourth pipe fitting 24 respectively. The first pipe fitting 21 is located below the second pipe fitting 22, the third pipe fitting 23 and the fourth pipe fitting 24. The second pipe fitting 22, the third pipe fitting 23 and the fourth pipe fitting 24 are arranged on the same horizontal plane. The third pipe fitting 23 is arranged parallel to the first pipe fitting 21.

[0024] The frame unit 20 plays a key supporting and protecting role, which is surrounded by the first to fourth tubes 24 connected in sequence by welding to form a rectangular frame around the battery body 10, and can stably support the battery body 10 in all directions. The support seat 11 of the side wall where the electrical connection port 12 is located is connected with the first tube 21.

[0025] The first tube 21 is located below the second, third and fourth tubes 24, providing bottom support for the electrical connection end, reducing the risk of damage to the electrical connection end due to vibration, impact and the like. Since the support seat 11 of the side wall where the electrical connection port 12 is located is connected with the first tube 21, the lower position of the first tube 21 can provide stable bottom support for the electrical connection port 12.

[0026] When the vehicle encounters bumps, vibrations or impact forces from below during driving, the first tube 21 can first receive and disperse these forces, avoiding direct force on the electrical connection port 12 and reducing the risk of port loosening or damage.

[0027] In a possible collision scenario, the first tube 21 at a lower position acts as a solid defense line, effectively buffering the impact energy from below and part of the side below, preventing deformation and fracture of the electrical connection port due to severe impact, thereby ensuring the integrity and stability of the electrical connection port and ensuring that the electrical connection performance of the power battery is not affected, providing reliable protection for the normal operation of the power battery.

[0028] The parallel arrangement of the first tube 21 and the third tube 23 makes the frame overall neat, while ensuring the supporting and protecting performance, maximizes the use of space around the battery, provides more space for the layout of other components in the vehicle, and is conducive to efficient use of the overall vehicle space, optimizing the overall vehicle structure design.

[0029] On the other hand, the first tube 21 is arranged at a lower position, which has a positive impact on space utilization in the height direction. Since the second tube 22, the third tube 23 and the fourth tube 24 are located at the same horizontal plane, they form a relatively neat upper frame structure, while the first tube 21 at a lower position closely adheres to the relevant position of the bottom of the battery body 10 and forms a staggered layout with other tubes. This layout method fully ensures the supporting and protecting performance of the power battery body 10, especially the electrical connection port, while avoiding space redundancy in the height direction.

[0030] Compared with the conventional design of arranging all tubes at the same height, the present structure lowers the position of the first tube 21, making the frame more reasonable in the height direction. In the limited space of the vehicle, more possibilities are provided for the arrangement of other components above and around the battery, improving the overall space utilization rate, which helps to realize the compactness and rationalization of the internal structure layout of the vehicle, thereby optimizing the space utilization efficiency of the vehicle without affecting the performance of the power battery.

[0031] The support base 11 comprises a mounting plate 111 on which the fastener 30 is connected, and a reinforcing plate 112, the top of which is connected to the mounting plate 111 and the side of which is connected to the side wall.

[0032] Further, the fastener 30 is provided with a gasket, the height dimension of the reinforcing plate 112 of the support base 11 connected to the first pipe 21 is smaller than the height dimension of the reinforcing plate 112 of the support base 11 connected to the second pipe 22, the height dimension of the reinforcing plate 112 of the support base 11 connected to the second pipe 22 is equal to the height dimension of the reinforcing plate 112 of the support base 11 connected to the third pipe 23 and equal to the height dimension of the reinforcing plate 112 of the support base 11 connected to the fourth pipe 24.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
