In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Referring to fig. 1 to 6, the present embodiment provides a battery box bracket of an electric traction vehicle, including a battery bracket 4, a bracket support structure 3 and a frame assembly 1.
The battery bracket 4 is used for supporting the battery box 2, the bracket supporting structure 3 is fixedly connected with the battery bracket 4, and the frame assembly 1 is fixedly connected with the bracket supporting structure 3. The frame assembly 1 comprises a top beam, a bottom beam, an angle column 103 and a middle column 106, wherein two ends of the angle column 103 are respectively and fixedly connected with the end part of the top beam and the end part of the bottom beam, and two ends of the middle column 106 are respectively and fixedly connected with the middle part of the top beam and the middle part of the bottom beam. A plurality of middle uprights 106 (two in this embodiment) are arranged between two corner uprights 103 connected to the same top beam, and a bracket support structure 3 is fixed to each middle upright 106.
For the electric traction vehicle, the number of the used battery boxes 2 is large, the weight is large, and the length of the battery bracket 4 is correspondingly large. Taking the present embodiment as an example, two battery cases 2 need to be arranged in parallel in the longitudinal direction of the battery bracket 4 (in the present embodiment, in the direction of the bracket longitudinal beam 401) on each layer of the battery bracket 4. If the battery bracket 4 is directly fixed to the corner post 103 (for example, CN 214607050U) without using the middle post 106, the middle portion of the battery bracket 4 is not supported and is easily broken. In this embodiment, a plurality of middle upright posts 106 are arranged between two corner upright posts 103 connected with the same top beam, and each middle upright post 106 is fixedly provided with a bracket supporting structure 3, and the middle part of the battery bracket 4 is supported by the plurality of middle upright posts 106, so that the middle part of the battery bracket 4 is prevented from being broken as much as possible, and the structural stability of the battery bracket is improved.
As a possible example, in the present embodiment, a plurality of middle posts 106 (two in the present embodiment) are uniformly distributed between two corner posts 103 connecting the same top beam, that is, the middle posts 106 support the battery carrier 4 at longitudinally equally divided positions. The bracket support structure 3 includes a support 301 and a riser 302, the support 301 being fixedly connected to the riser 302. The upright plates 302 include a plurality of upright plates 302, and the plurality of upright plates 302 are fixedly connected to two sides of the same middle upright 106. The support 301 is fixedly connected to the battery carrier 4. Other types of bracket support structures 3, such as bolts and nuts, which pass through the battery bracket 4 and the center post 106, and which are threaded, may also be selected by those skilled in the art, depending on the actual needs.
As a possible example, in the present embodiment, the support 301 has two mutually perpendicular plate surfaces that contact the bottom surface and the side surfaces of the battery bracket 4, respectively. A groove is provided at the vertical edge of the vertical plate 302, and the supporting member 301 is embedded in the groove. Specifically, in this embodiment, the supporting member 301 is an angle steel, and the supporting member 301 is welded to the groove of the vertical plate 302. By bringing the two plate surfaces of the support 301 into contact with the bottom surface and the side surfaces of the battery bracket 4, respectively, the battery bracket 4 can be more preferably restrained. By embedding the support 301 in the recess, the support 301 can be positioned by the recess on the one hand and the lower side walls of the recess on the other hand provide support for the support 301.
As a possible example, in this embodiment, the frame assembly 1 has a square frame structure as a whole. Specifically, the top beam includes two top cross members 104 and two top stringers 105 perpendicular to the top cross members 104, and the two top cross members 104 and the two top stringers 105 enclose a top rectangle. The bottom beam comprises two bottom beams 102 and two bottom stringers 101 perpendicular to the bottom beams 102, the two bottom beams 102 and the two bottom stringers 101 enclosing a bottom rectangle. The corner posts 103 include four, and two ends of the corner posts 103 are fixedly connected to the ends of the top stringers 105 and the ends of the bottom stringers 101, respectively. The middle of the top stringer 105 and the middle of the bottom stringer 101 are fixedly connected at the both ends of the middle pillar 106, respectively. Other shapes of the frame assembly 1 may be selected by those skilled in the art, depending on the actual needs.
As a possible example, in the present embodiment, the frame assembly 1 further includes a middle reinforcement beam 107, an edge reinforcement beam 108, and a side reinforcement beam 109, where the middle reinforcement beam 107 and the edge reinforcement beam 108 are located between the top longitudinal beam 105 and the bottom longitudinal beam 101, and the side reinforcement beam 109 is located between the top cross beam 104 and the bottom cross beam 102. The top stringers 105 are connected to the bottom stringers 101 by a plurality of center posts 106.

Therefore, in this embodiment, the battery box 2 is one more layer than the battery holder 4, the battery box 2 is 6 layers, and the battery holder 4 is 5 layers. Since the battery bracket 4 is not provided below the lowermost battery box 2, the first harness water pipe bracket 119 (which has the same structure as the second harness water pipe bracket 403) corresponding to the lowermost battery box 2 is arranged on the lowermost middle reinforcement beam 107 or the bottom side reinforcement beam 108.
As a possible example, in this embodiment, reinforcing plates are welded and fixed at the connection positions of the top beam and the corner post 103, the bottom beam and the corner post 103, the top beam and the middle post 106, and the bottom beam and the middle post 106. The reinforcement plate is welded to both structures (e.g., header and corner posts 103) at the connection locations at the same time to increase the strength of the connection of the two structures. The reinforcing plates comprise side welding reinforcing plates 110 and middle welding reinforcing plates 113, the side welding reinforcing plates 110 are positioned at the connection positions of the top beams and the corner uprights 103 and the bottom beams and the corner uprights 103, and the middle welding reinforcing plates 113 are positioned at the connection positions of the top beams and the middle uprights 106 and the bottom beams and the middle uprights 106.

A plurality of limiting blocks 116 are fixed on each supporting cross beam, and the limiting blocks 116 limit the two bottom longitudinal beams 101 respectively. In this embodiment, the stopper 116 is not in direct contact with the bottom rail 101, and a reinforcing plate is disposed between the stopper 116 and the bottom rail 101. One of the outer side plate surfaces of the V-shaped bracket 115 is fixedly connected with limiting blocks 116 on the two supporting beams at the same time, so that the relative positions of the two supporting beams are guaranteed, and an included angle is formed between the other outer side plate surface of the V-shaped bracket 115 and the top surface of the supporting beam. Both ends of the diagonal brace 118 are fixedly connected to the end of the bottom girder 101 and the side surfaces of the supporting cross member, respectively, to support the end of the bottom girder 101.
