Description

TECHNICAL FIELD

[0001] The utility model relates to the field of battery box production, concretely relates to a battery box structure for micro truck. BACKGROUND

[0002] At present, battery box design occupies an important position in the field of new energy vehicles. However, the existing battery box design generally has the problems of large size, complex structure and high cost. These designs not only limit their application in certain vehicle models, but also increase the manufacturing and maintenance cost of the whole vehicle.

[0003] Firstly, the existing battery box is large in size, which is particularly prominent in commercial micro truck models. Due to the small size of the frame of such vehicles, the traditional battery box is difficult to adapt to the space requirements, affecting the design and aesthetics of the whole vehicle. At the same time, the large size also increases the weight of the vehicle, affecting the handling and passability.

[0004] Secondly, the complex internal structure of the battery box will cause the connection lines of the battery module to be distributed in a staggered manner during assembly, especially in places where multiple wires are staggered, which will cause a large amount of heat accumulation, which is not conducive to the heat dissipation of the battery itself, causing the power release of the battery itself to be hindered.

[0005] Therefore, in the face of these problems, it is urgent to develop a new box with small size and simple structure. This new box not only needs to be optimized in size to adapt to the compact frame space, but also needs to be simplified in structure design to reduce the probability of complex and disorderly connection lines of the battery module.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Refer to the attached Figure 1 -Attached Figure 4 The present invention provides an embodiment of a battery box structure for a mini truck. The battery box structure includes a box for housing batteries, wherein a first longitudinal beam and a second longitudinal beam are arranged parallel to each other along the length of the box. The first longitudinal beam is positioned on one side of the box, while the second longitudinal beam is positioned on the opposite side of the first longitudinal beam. The two longitudinal beams are aligned at the same height to provide uniform support.

[0031] The first longitudinal beam is composed of a Z-shaped first support portion and a rectangular tubular first connecting portion, with the upper end of the first support portion connected to the side of the first connecting portion. The second longitudinal beam is composed of a U-shaped second support portion and a rectangular tubular second connecting portion, with the upper end of the second support portion connected to the side of the second connecting portion. This structural design effectively improves the load-bearing capacity and stability of the box.

[0032] The first support portion and the second support portion are provided with through holes at the same position in the transverse direction. These through holes are used to pass through the battery module wires to ensure smooth connection of the electrical connection lines.

[0033] Furthermore, in order to enhance the stability of the overall structure of the first longitudinal beam and the second longitudinal beam, the first supporting portion and the first connecting portion, as well as the second supporting portion and the second connecting portion are connected by welding.

[0034] Furthermore, in the design of the first longitudinal beam and the second longitudinal beam of the present application, the corner angle of the first support portion and the second support portion is 90 degrees, and they are formed by sheet metal stamping; such a design can not only ensure the accuracy of the structure, but also facilitate manufacturing and assembly.

[0035] An electrical mounting plate is installed between the second longitudinal beam and the inner wall of the box. It is used to secure the electrical components within the box and is connected to the lower box and the second longitudinal beam via welding. The central portion of the electrical mounting plate features a square hole, which helps reduce cost and weight. Specifically, the square hole can measure 116mm x 64.7mm.

[0036] The box body of the utility model is composed of an upper box body and a lower box body, which are connected by self-tapping screws 10. Among them, the upper box body and the lower box body are both stamped by sheet metal and bent at a 90-degree angle, which helps to reduce dead angles during spraying and electroplating and improve the uniformity and quality of the coating.

[0037] Refer to the attached Figure 1 -Attached Figure 2 The lower case is equipped with multiple lifting lugs. Lifting lugs #1, #2, #3, and #4 are all stamped from sheet metal, identical in size, and feature a 90-degree bend. Furthermore, the lugs are connected to the lower case via a welding process to enhance connection strength. They are primarily used to secure the battery case to the vehicle frame.

[0038] Since the upper box body and the lower box body of the present invention are formed by bending sheet metal and then welding, the outer surfaces of the upper box body and the lower box body can be treated by electrophoresis and plastic spraying, especially the bottom of the lower box body, a 2mm PVC coating can be added; thereby, the present application can effectively prevent the bottom from being soaked in water and hit by gravel.

[0039] The battery box structure design of the utility model has passed mechanical simulation analysis and vibration verification testing, ensuring the safety and reliability of the battery box in practical applications.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
