[0029] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-Figure 6 As shown, a battery anti-collision structure in this embodiment includes a battery body 1 and a subframe 2 arranged on the front side of the battery body 1, and also includes a battery anti-collision beam assembly 4 and a bottom protection plate 3 arranged on the lower side of the subframe 2; the battery anti-collision beam assembly 4 includes an anti-collision beam body 41 and a mounting bracket 42, the anti-collision beam body 41 is connected to the subframe 2 through the mounting bracket 42, and the lowest point of the anti-collision beam body 41 is lower than the lowest point of the battery body 1; the bottom protection plate 3 of the battery anti-collision beam assembly 4 is provided with an envelope groove corresponding to the position of the battery anti-collision beam assembly 4, and the anti-collision beam body 41 partially protrudes downward from the envelope groove. Among them, the battery body 1 can be a power battery.

[0031] Since the lowest point of the anti-collision beam 41 is lower than the lowest point of the battery body 1, and the subframe 2, the battery anti-collision beam assembly 4 and the bottom protection plate 3 are all located in front of the battery body 1, when the car encounters low obstacles such as potholes and stones during driving, the first part to be hit is the anti-collision beam 41, which can reduce the probability of the battery body 1 being hit, improve the safety performance of the battery body 1, and improve the safety of the entire vehicle. In addition, most of the battery anti-collision beam assembly 4 is enclosed in the enveloping groove of the bottom protection plate 3, such as Figure 3 As shown, only the lower part of the anti-collision beam body 41 protrudes downward from the envelope groove, which can maintain the overall flatness of the bottom of the vehicle and effectively prevent obstacles (such as branches, plastic garbage, etc.) from hooking on the battery anti-collision beam assembly 4 and causing continuous damage to the bottom of the vehicle. In addition, the battery anti-collision beam assembly 4 and the bottom protection plate 3 also have the advantages of simple structure and low manufacturing cost.

[0032] In this embodiment, the envelope groove includes a clearance groove 31 and a conformal groove 32. The position of the clearance groove 31 corresponds to the position of the mounting bracket 42, and the conformal groove 32 corresponds to the position of the anti-collision beam body 41. The lower part of the anti-collision beam body 41 protrudes downward from the conformal groove 32. In this embodiment, the anti-collision beam body 41 is a straight round tube, and the axis of the anti-collision beam body 41 extends along the width direction of the vehicle, wherein the width direction of the vehicle is the left and right direction of the vehicle. The mounting bracket 42 is connected to the subframe 2, and the clearance groove 31 can make way for the mounting bracket 42. The anti-collision beam body 41 is a straight round tube, so the conformal groove 32 is an arc-shaped groove that matches the shape of the straight round tube. The conformal groove 32 envelops the upper part of the straight round tube, and the lower part of the straight round tube protrudes downward from the conformal groove 32, which plays a role in protecting the battery body 1. At the same time, straight round tubes do not require bending features, which can reduce the bending process, achieve lightweight and simplification, reduce the number of operating procedures during manufacturing and reduce manufacturing costs.

[0033] In this embodiment, the length of the anti-collision beam 41 is less than the inner lateral spacing of the two wheels of the vehicle. The anti-collision beam 41 is connected to the subframe 2 through the mounting bracket 42, and does not need to be installed on the longitudinal beams on both sides of the vehicle, which shortens the length of the anti-collision beam 41 and further reduces the manufacturing cost.

[0034] In this embodiment, two mounting brackets 42 are provided, and the two mounting brackets 42 are spaced apart in the vehicle width direction.

[0035] In this embodiment, the mounting bracket 42 includes a bracket body 421 and two mounting flanges 422 respectively arranged on the left and right sides of the bracket body 421. The bracket body 421 is connected to the sub-frame 2, and the two mounting flanges 422 are connected to the anti-collision beam body 41. Specifically, the bracket body 421 is connected to the sub-frame 2 through a threaded fastener 5, and the two mounting flanges 422 are provided with mounting grooves 423. The mounting grooves 423 are conformally fitted to the anti-collision beam body 41, and the mounting flanges 422 are connected to the anti-collision beam body 41 by welding. During installation, the bottom guard plate 3 is first connected to the sub-frame 2, and then the bracket body 421 is passed through the clearance slot 31 and the bracket body 421 is connected to the sub-frame 2 through the threaded fastener 5, which can be easily disassembled.

[0036] In this embodiment, the bracket body 421 is provided with two bolt through holes 424 , and an escape notch 425 is provided between the two bolt through holes 424 . The escape notch 425 can escape the downwardly protruding mounting studs or mounting bolt structures 21 on the sub-frame 2 .

[0037] In this embodiment, the battery pipeline 11 of the battery body 1 is arranged on the upper side of the battery anti-collision beam assembly 4 and the bottom protection plate 3. The battery anti-collision beam assembly 4 and the bottom protection plate 3 can also protect the battery pipeline 11 of the battery body 1.

[0038] A car in this embodiment includes the battery anti-collision structure.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
