Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] like figure 1 The power battery box with telescopic function shown in —7 includes a battery box body 1, a positioning pin bracket 6 is respectively fixed on the middle surface of the left and right sides of the battery box body 1, and a vertically upward Locating pin 3 arranged.
[0025] The left and right sides of the battery box 1 are respectively fixed with two drawer-type telescopic structures arranged front and back. The drawer-type telescopic structure includes a fixed box body 4 fixed on the side surface of the battery box body 1 and a fixed box body 4 that can be matched with each other. The sliding box body 5 that translates to the inside or outside of the fixed box body 4, the fixed box body 4 is fixed on the surface of the battery box body 1, and the surface of the side away from the battery box body 1 is provided w...

The invention discloses a power battery box with a side edge having a telescopic function and a vehicle body mounting structure thereof. The power battery box comprises a battery box body, and the battery box body is provided with a positioning pin capable of being matched with a vehicle body bottom plate assembly for positioning and drawer type telescopic structures capable of being matched and fixed with the vehicle body bottom plate assembly; and the drawer type telescopic structure comprises a fixed box body fixed on the side surface of the battery box body and a sliding box body which is matched with the fixed box body and can translate towards the inner side or the outer side of the fixed box body relative to the fixed box body, and a position maintaining structure is fixedly connected between the fixed box body and the sliding box body, wherein the position maintaining structure can enable the sliding box body to be maintained on the outer side of the fixed box body and at a locking position matched with the vehicle body bottom plate assembly or enable the sliding box body to be maintained on the inner side of the fixed box body and at an unlocking position matched with the vehicle body bottom plate assembly. The battery box is hung in clamping grooves in the two sides of the vehicle body bottom plate assembly through the drawer type telescopic structures on the side edges of the battery box, the stretching and retracting of the drawer type telescopic structures are controllable, and the locking mechanism is arranged, so that the purpose of quickly mounting and dismounting the power battery box is achieved.
Description
technical field [0001] The invention relates to the technical field of automobile power batteries, in particular to a power battery box with a telescoping function on the sides and a vehicle body installation structure thereof. Background technique [0002] The promotion of pure plug-in electric vehicles is affected by reasons such as short driving range and long charging time. If the battery is quickly disassembled after the battery is exhausted, and the pre-charged battery is quickly installed, the continuous operation of the vehicle can be guaranteed. This is a new direction for the development of electric vehicles. The rapid replacement of the power battery system can be realized by means of the replacement equipment at the power station. So what kind of fixing method is used for the power battery box on the vehicle body to realize the quick replacement of the battery box itself is the current problem. The ordinary bolt connection is obviously Can not meet the needs of ...
