[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] See Figures 1 to 6 As shown, an embodiment of the present invention provides a battery bracket 10 for being installed on a vehicle frame 6 to fix a power battery 5, for example, being installed on an electric truck having a vehicle frame 6, or other vehicles having a vehicle frame, to fix the power battery 5. The power battery 5 can be a box-shaped battery, or a battery formed by fixing a cell assembly on a frame body and covering the frame body with a layer of skin, or a battery of other shapes having a bottom and two sides that need to be supported. The battery bracket 10 includes a bracket body 2 extending along a first direction and fixed to the vehicle frame 6, a transverse support portion 3 extending along a second direction and fixedly connected to the bracket body 2, and a vertical support portion 4 extending along a third direction and fixedly connected to the bracket body 2. The first direction can be understood as the front-to-back direction on the horizontal plane, the second direction can be understood as the left-to-right direction on the horizontal plane, and the third direction can be understood as the vertical direction perpendicular to the horizontal plane. The lateral support portion 3 is provided with a horizontal support surface 103 for supporting the bottom of the power battery 5, and the vertical support portion 4 is provided with a vertical support surface 104 for supporting the power battery 5 from the side. The power battery 5 can also be fixed to the horizontal support surface 103 and the vertical support surface 104 respectively by bonding, bolting, or welding. Preferably, the lateral support portion 3 and the vertical support portion 4 are fixedly connected. Furthermore, the bracket body 2, lateral support portion 3, and vertical support portion 4 are each formed by bending aluminum alloy plates and welded together.

[0030] The bracket body 2 includes a horizontally arranged flat plate portion 21 and a fixing portion 22 formed by bending 90 degrees from the flat plate portion 21. Preferably, the flat plate portion 21 is designed to be no greater than the width of the steel beam (unnumbered) selected for the frame, and the fixing portion 22 is designed to be no greater than the height of the steel beam selected for the frame. In other words, the flat plate portion 21 has a certain length along the first direction and a certain width along the second direction, and the fixing portion 22 has a certain height along the third direction. The flat plate portion 21 and the fixing portion 22 are finally simultaneously fitted and fixed to the frame 6 by means of welding or clamps 61. The transverse support portion 3 includes a vertically arranged support plate 32, and the support plate 32 is provided with an L-shaped edge, which is fixedly connected to the flat plate portion 21 and the fixing portion 22 respectively through the L-shaped edge.

[0031] Specifically, the transverse support portion 3 includes a horizontally disposed load-bearing plate 33, a vertically disposed support plate 32 bent vertically downward from one side of the load-bearing plate 33, and a vertically disposed connecting plate 34 bent vertically downward from the other side of the load-bearing plate 33. The connecting plate 34 is fixedly connected to the vertical support portion 4. The support plate 32 is fixedly connected to the flat plate portion 21 via the short side of the aforementioned L-shaped edge. It is understood that the load-bearing plate 33 is designed to be taller than the flat plate portion 21. The flat plate portion 21 is used to secure the battery holder 10 to the vehicle frame 6, while the load-bearing plate 33 is used to support the bottom of the power battery 5. Preferably, the support plate 32 and connecting plate 34 are parallel to each other and each have a triangular outer profile. The area of the support plate 32 is larger than that of the connecting plate 34. Furthermore, the support plate 32 is provided with a hole 321, preferably a triangular hole 321, to reduce weight and save material.

[0032] The vertical support portion 4 includes a first side wall (not numbered) extending vertically in the third direction, and two second, generally triangular side walls (not numbered) connected to the first side wall. The first and second side walls form a columnar reinforcing arm 42, the bottom of which is fixedly mounted on the flat plate portion 21. Specifically, the support portion 4 includes the reinforcing arm 42 mounted on the flat plate portion 21 and a reinforcing plate 43 extending downward from a second side wall of the reinforcing arm 42 and abutting against the fixing portion 22. The provision of the reinforcing plate 43 ensures a secure connection between the reinforcing arm 42 and the bracket body 2. For example, the bottom of the reinforcing arm 42 can be welded to the flat plate portion 21 and the reinforcing plate 43 can be secured to the fixing portion 22 of the bracket body 2 using bolts and nuts. Alternatively, the reinforcing arm 42 and the reinforcing plate 43 can be separately welded to the bracket body 2, thereby simultaneously securing the fixed support portion 4 to the bracket body 2 from two sides. This can achieve a reliable and stable connection.

[0033] The upper side of the load-bearing plate 33 forms the horizontal support surface 103. The vertical support portion 4 includes the aforementioned vertically extending reinforcement arm 42 and an abutment plate 41 disposed at the upper end of the reinforcement arm 42. One side of the abutment plate 41 is in close contact with the reinforcement arm 42, and the other side forms the vertical support surface 104. In other embodiments, the abutment plate 41 can be integrally designed with the reinforcement arm 42, further eliminating the need for the close contact step, which will not be described in detail here.

[0034] Preferably, the lateral support portion 3 and the vertical support portion 4 respectively have a triangular outer contour, and therefore have a strong supporting strength. It is worth mentioning that the triangle mentioned in this article is not an absolute triangle in geometry, and may be a part having only three sides of a triangle, such as a triangle with rounded corners at the vertex, or a triangle without a vertex. In other words, it can be considered that: the main part of the lateral support portion 3, the vertical support portion 4 and the projection line of the aforementioned hole 321 on a certain surface have three non-parallel sides, and these three sides can form a triangle when extended.

[0035] The present invention also provides an electric truck, comprising a front end (not shown) and a frame 6. A power battery 5 is mounted on the frame 6. The power battery 5 has a horizontal bottom, a front side proximal to the front end, and a rear side distal to the front end. For example, the power battery 5 is in the form of a box. The power battery 5 provides electrical energy, enabling the electric truck to generate kinetic energy. Multiple battery holders 10 are spaced apart and arranged in pairs on the frame 6. Specifically, the two pairs of battery holders 10 are arranged in mirror-image symmetry. The frame 6 has two parallel crossbeams extending in a first direction. A pair of battery holders 10 is mounted on each of the crossbeams. Each pair of battery holders 10 has two vertical support surfaces 104 facing each other and aligned with the other pair of vertical support surfaces 104 in a second direction. In this embodiment, four battery holders 10 support and secure the power battery 5. The bottom of the power battery 5 is supported by a horizontal support surface 103 of the battery holder 10. The front and rear sides of the power battery 5 are each clamped and secured by a plurality of vertical support surfaces 104.

[0036] Preferably, the power battery 5 can be formed by stacking multiple box-shaped battery modules 50 along a third direction. Each battery module 50 has a housing (unnumbered) constructed of aluminum alloy sheet material. Two adjacent battery modules 50 are fixed together by connecting the housings to edges (unnumbered) of the housings, for example, via bolts and nuts. Stacking the multiple housings ultimately forms the box-shaped housing of the power battery 5. The vertical support surface 104 on the vertical support portion 4 has a length in the third direction no less than the thickness of a single battery module 50, and the vertical support surface 104 is fixedly connected to at least two battery modules 50. More specifically, the abutment plate 41 on the support portion 4 is provided with a plurality of vertically arranged mounting holes (unnumbered). Bolts extending through the mounting holes are respectively secured to the edges of the housings of two or more battery modules 50. In other embodiments, the power battery 5 may also have a frame structure. In this case, it is sufficient to securely connect the abutment plate 41 to the frame structure using bolts, which will not be described in detail here. This installation method means that the power battery 5 can be removed from the vehicle frame 6 and is easy and secure to install.

[0037] The battery bracket 10 according to the present invention is lightweight, has a simple structure and is easy to process. When used to fix the power battery 5, since it is arranged in pairs and independently, the connecting material between the brackets is eliminated, which can make the electric truck with the battery bracket 10 more lightweight, while also having good stability and easy assembly.

[0038] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
