DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figures 1-4, a battery support structure for a new energy vehicle chassis, includes a front bumper 12 and two chassis brackets 8 arranged side by side. The chassis brackets 8 have battery accommodation grooves 9. The chassis brackets 8 are arranged along the length direction of the vehicle. Each chassis bracket 8 is connected to the front bumper 12 through a front bracket 11, and the two front brackets 11 are distributed in a "V" shape. The adjacent sides of the two chassis brackets 8 are fixed by a plurality of connecting members 2 arranged along the width direction of the vehicle. The front bumper 12 is provided with a cutting rod 13 that can cut the connecting member 2 along the length direction of the vehicle.
[0020] Reference Figure 1 、 Figure 3 , this device is provided with two chassis brackets 8, and the two chassis brackets 8 are connected to the front bumper 12 through the front brackets 11 distributed in a "V" shape. When the vehicle is impacted head-on, after the front bumper 12 is impacted, it transmits the impact force to the front brackets 11. Reference Figure 3 , the front brackets 11 distributed in a "V" shape will cause the two chassis brackets 8 to turn outwards, reducing the pressure on the battery inside the chassis brackets 8 and lowering the probability of the battery catching fire and exploding due to extrusion. And during the process of the cutting rod 13 cutting the connecting member 2, it can also absorb a certain amount of impact force. Generally speaking, it can improve the safety of passengers.
[0021] Reference Figure 1 、 Figure 2 , the front bracket 11 includes a first connecting rod 17, a first pin shaft 15, and a second pin shaft 19. The front bumper 12 is fixedly connected with a first connecting portion 16. One end of the first connecting rod 17 is rotatably connected to the first connecting portion 16 through the first pin shaft 15. The front end of the chassis bracket 8 is fixedly connected with a second connecting portion 18. The other end of the first connecting rod 17 is rotatably connected to the second connecting portion 18 through the second pin shaft 19. When the front bumper 12 is impacted head-on, it can apply a component force along the width direction of the vehicle to the chassis bracket 8 through the first connecting rod 17. Both ends of the first connecting rod are rotatably connected to the front bumper 12 and the chassis bracket 8 respectively, and the first connecting rod 17 is arranged in an inclined outward manner. When the front bumper 12 is impacted head-on, the first connecting rod 17 will push the chassis bracket 8 to turn outwards in the width direction of the vehicle, reducing the probability of the battery being extruded.
[0022] As an implementation manner of the connecting member, the connecting member 2 includes a bolt 6. The length of the bolt 6 is arranged along the width direction of the vehicle. One end of the bolt 6 is fixed to one chassis bracket 8, and the other end of the bolt 6 is fixed to the other chassis bracket 8; specifically, the chassis bracket 8 includes a side plate 1. At least one end of the bolt 6 has a threaded head 5 passing through the side plate 1, and a limiting portion 3 and a nut member 4 are provided on the threaded head 5. The limiting portion 3 and the nut member 4 are respectively clamped on both sides of the side plate 1. The two chassis brackets 8 are fixed along the width direction of the vehicle by bolts, and since the bolt 6 is arranged along the width direction of the vehicle, it is convenient for the cutting rod 13 to cut it radially.
[0023] Reference Figure 1 、 Figure 4 The truncated rod 13 includes a main rod portion 22. The main rod portion 22 is fixed to the front bumper 12 and is arranged along the length direction of the vehicle. A plurality of blade portions 10 are fixedly connected to the main rod portion 22, and each blade portion 10 corresponds to a connecting member 2.
[0024] At least one blade portion 10 is provided on the foremost connecting member 2. When the front bumper 12 is impacted frontally, the front bumper 12 pushes the truncated rod 13 to move along the length direction of the vehicle, and the bolt 6 is truncated by the blade portion 10, facilitating the outward turning and separation of the two chassis brackets 8.
[0025] As an implementation manner, a brittle connecting rod 14 is fixedly installed between each chassis bracket 8 and the front bumper 12. For example, a ceramic rod or a tempered glass rod is used. The chassis bracket 8 and the front bumper 12 are connected by the brittle connecting rod 14 to improve the connection stability between the chassis bracket 8 and the front bumper 12. When impacted, the brittle connecting rod 14 breaks. On the one hand, it can buffer the impact force, and on the other hand, it does not affect the outward turning and separation of the two chassis brackets 8.
[0026] As an implementation manner, the support structure includes a rear bumper 21, and each chassis bracket 8 is fixed to the rear bumper 21 through a support rod 20. The rear bumper 21 is fixed to the chassis bracket 8 by the support rod 20, so that the two chassis brackets 8 can turn outwards in a V shape. At the same time of turning outwards, the support rod 20 will deform and can absorb part of the impact force.
[0027] The above is only a preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes to obtain technical solutions, concepts, and designs, which should all be covered within the protection scope of the present utility model.
