Problems solved by technology

At present, the protection of the external output part of the battery pack is made of plastic plates, which can only protect the mud, water, sand, etc. splashed from the ground during the driving process of the car, and the impact resistance is poor; The protective plate that protects the output part of the package, the battery pack box and the body are connected by rigid bolts. During the movement of the vehicle, due to the twisting of the body, the protective plate, the battery pack box and the body will be damaged. There is a pulling phenomenon at the connection points between them, which can easily cause damage to these connection points. Therefore, finding a protective plate that can protect the output part of the battery pack and the connection points between the battery pack box and the body can avoid It is a very meaningful thing for the connection structure damaged due to the pulling phenomenon of the electric vehicle during driving

Embodiment 1

[0019] Such as Figure 1-Figure 7 As shown, the present invention includes a battery pack box body 1 , a vehicle body subframe 2 , a fender 3 , and a fender liner 4 . Wherein, the protective plate 3 is a steel plate product. The guard plate bushing 4 includes a metal lining core 4.1, a rubber lining core jacket 4.2; the rubber lining core jacket 4.2 includes a core upper layer 4.21, a core middle layer 4.22, and a core lower layer 4.23. The upper and lower ends of the core middle layer 4.22 are respectively connected to the lower end of the upper core layer 4.21 and the lower end of the lower core layer 4.23; the outer diameter of the main body 4.11 of the metal lining core 4.1 is smaller than the outer diameter of the lining flange 4.12 of the metal lining core 4.1, and the lining core The main body 4.11 and the lining flange 4.12 are provided with main body through holes adapted to the bolt 5; the free height of the rubber lining jacket 4.2 is greater than the length of the...

Embodiment 2

[0021] The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the guard plate bushing 4 is located at the part where the guard plate 3 and the subframe 2 of the vehicle body are connected, and accordingly, the guard plate 3 is close to the side of the subframe 2 of the vehicle body The corresponding part is provided with a U-shaped connecting groove adapted to the core middle layer 4.22, and the shield bushing 4 is connected with the body subframe 2 through the bolt 5 passing through the through hole of the main body so as to realize the connection between the shield and the body. The protective plate and the battery pack case 1 are connected by a known bolt connection structure.

Abstract

A connecting structure between a battery pack output part protection plate and a battery pack box body or a vehicle body comprises the battery pack box body, a vehicle body auxiliary frame, the protection plate made of a steel plate, and an auxiliary plate bushing. The auxiliary plate bushing comprises a metal lining core and a rubber lining core outer sleeve. The rubber lining core outer sleeve comprises an upper core layer, a middle core layer and a lower core layer. a main body through hole is formed in the lining core main body and the lining core flange of the metal lining core. The freeheight of the rubber lining core outer sleeve is larger than the length of the lining core main body, and the working height of the rubber lining core outer sleeve is equal to the length of the liningcore main body. The lining core main body is inserted into an outer sleeve through hole. The auxiliary plate bushing is arranged on one side, positioned on a connecting frame on the battery pack boxbody, of the protection plate, or is arranged on one side, positioned on the vehicle body auxiliary frame, of the protection plate. The core middle layer is located in a U-shaped connecting groove formed in the protection plate, the lower surface of the core upper layer is attached to the upper surface of the protection plate, and the upper surface of the core lower layer is attached to the lowersurface of the protection plate. The output part of the battery pack cannot be damaged by mud, water, sands and the like in the driving process.

Description

technical field [0001] The present invention relates to an engine component, in particular to a connection point between the protective plate protecting the output part of the battery pack, the battery pack box body and the vehicle body from being damaged due to the pulling phenomenon of the electric vehicle during driving connection structure. Background technique [0002] Today, with the rapid development of science and technology, electric vehicles have been widely promoted, and battery packs are an indispensable part of electric vehicles, so it is particularly important to strengthen the protection of battery packs. The protection of the battery pack includes the protection of the external output connection part of the battery pack. At present, the protection of the external output part of the battery pack is made of plastic plates, which can only protect the mud, water, sand, etc. splashed from the ground during the driving process of the car, and the impact resistance...
