The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The side collision separation type battery pack mounting structure provided by the embodiment of the utility model comprises: the power battery 1, the lateral fixing member and the vehicle body member, the structure of which can be seen with reference to fig. 1 and 2;
the power battery 1 is mounted on the vehicle body part through a transverse fixing part, and the transverse fixing part can provide transverse limit for the power battery 1 and plays a role in fixing under normal conditions; it can be understood that the running direction of the automobile is longitudinal (i.e. front-back, as in the X-axis direction of fig. 1), and the transverse direction is perpendicular to the longitudinal direction in the horizontal plane, i.e. left-right, as in the Y-axis direction of fig. 1;
the transverse fixing piece is of an actively releasable structure, can release transverse limit and allows the power battery 1 to move transversely in the event of collision.
According to the technical scheme, the lateral collision separation type battery pack mounting structure provided by the embodiment of the utility model has the advantages that the lateral limit of the lateral fixing piece can be relieved, so that the power battery 1 can move in the lateral direction when collision occurs, and compared with the situation that the existing battery pack is fixed on a vehicle body, the lateral collision separation type battery pack mounting structure can reduce the influence of collision on the power battery 1, so that the safety performance is improved;
in addition, the design requirement of the side surface structure of the vehicle body is reduced, and the lightweight design of the vehicle body structure is facilitated;
and the transverse fixing piece is of an actively releasable structure, so that the power battery 1 can be effectively protected in time before collision occurs.
Preferably, the transverse fixing element is a magnetic mechanism, which can provide a transverse limit for the power battery 1 by magnetic force. The magnetic force is used for fixation, so that the effect is firm, the control is convenient, and the recycling can be realized by repeated use. Of course, other mechanical structures may be used as the transverse fixing member, such as a clamping member, or may be actively collapsed, which will not be described herein.
Further, the transverse fixing member includes: a magnetic attraction plate 2 and an electromagnet 3, the structure of which can be seen with reference to fig. 2;
one of the magnetic attraction plate 2 and the electromagnet 3 is fixed to the power battery 1, and the other is fixed to a vehicle body member (here, may be specifically a vehicle body cross member 6). The electromagnetic force mechanism is adopted as a transverse fixing piece, so that the fixing effect can be ensured, the generation and release of transverse limit can be controlled conveniently, and the maintenance economy is realized. Of course, the permanent magnet can also be adopted, and the generation and release of the transverse limit can be realized by changing the distance between the permanent magnet and the magnetic attraction piece or arranging a magnetic barrier between the permanent magnet and the magnetic attraction piece.
The side collision separation type battery pack mounting structure provided by the embodiment of the utility model further comprises: a controller (not shown in the figure);
the controller is in communication connection with a pre-crash safety system of the automobile, and the controller can conduct power-off processing on the circuit of the electromagnet 3 after receiving an external crash signal. After the power is off, the electromagnetic force between the electromagnet 3 and the magnetic attraction plate 2 disappears, namely the transverse limit is canceled, so that the power battery 1 can move transversely. By means of the arrangement, the transverse limit can be released in time through linkage with the driving assistance technology. It should be noted that, the pre-crash safety system is in the prior art, and the present solution is only the acceptance of the external crash signal and the processing according to the preset manner, and does not involve improvement of the method.

The vehicle body position where the lateral guide mechanism is mounted may be the same as or different from the vehicle body member described above.
Further, the lateral guide mechanism includes: a slider 4 and a guide rail 5, the structure of which can be seen with reference to figure 2;
wherein, guide rail 5 is transversely mounted on the car body member, slider 4 is mounted on guide rail 5, slider 4 is mounted on power battery 1, so as to realize the transverse sliding of power battery 1.

the energy absorber is arranged on the lateral side face of the power battery 1, is positioned between the power battery 1 and the threshold beam 8, and can absorb the kinetic energy of the battery pack during collision without being born by the threshold, so that the design requirement of a side face structure of a vehicle body is reduced, and the energy absorber has great significance in light-weight design of the vehicle body structure.
Further, the energy absorbing device is an energy absorbing box 7, and the structure of the energy absorbing device can be shown by referring to fig. 1;
wherein, the energy absorption box 7 is detachably arranged at two lateral sides of the power battery 1. In the collision process, the power battery 1 slides towards the collision side under the action of inertia, the collision side energy absorption box 7 outside the battery pack contracts and deforms, the kinetic energy of the vehicle body is converted into the internal energy of the energy absorption box 7, then the battery pack moves to the non-collision side along with the collision direction, the side energy absorption box 7 deforms and absorbs energy, and the collision speed of the whole vehicle is reduced.
