Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a power battery module with anticollision protection shield, including battery module 1, first buffering subassembly 2 is the same with second buffering subassembly 3 structure and is the mirror image and install both ends around battery module 1, first buffering subassembly 2 with second buffering subassembly 3 includes baffle 21, bolster 22 and mounting panel 23 respectively, bolster 22 is installed baffle 21 with between the mounting panel 23, mounting panel 23 deviates from one side of bolster 22 with the connection can be dismantled to roof 11 and the bottom plate 12 of battery module 1, the left and right sides of battery module 1 still is provided with two arch buffer boards 4, buffer board 4 joint is between the mounting panel 23 at both ends in the front and back. Specifically, in the present embodiment, the top plate 11, the bottom plate 12 and the side plates 13 of the battery module 1 form a box with a sealing grade reaching IP67, and a plurality of batteries are connected in series and in parallel and then installed in the closed box. The front and rear edge portions of the top plate 11 and the bottom plate 12 are connected to the first cushion unit 2 and the second cushion unit 3, respectively. It should be noted that, in order to improve the production assembly efficiency and reduce the assembly difficulty, the first buffer assembly 2 and the second buffer assembly 3 are composed of a baffle 21, a buffer 22 and a mounting plate 23, and the mounting plate 23 is positively clamped between the top plate 11 and the bottom plate 12 and can be used as a bearing component to prevent the edges of the top plate 11 and the bottom plate 12 from collapsing during bearing. Still joint there are two arch buffer boards 4 at battery module 1's the left and right sides both ends, and during the equipment buffer board 4, can be connected first buffering subassembly 2 or second buffering subassembly 3 with battery module 1 earlier, and the second step is with buffer board 4 same joint between roof 11 and bottom plate 12, and finally, is connected second buffering subassembly 3 or first buffering subassembly 2 with roof 11, bottom plate 12, extrudees buffer board 4 and is the arch. When the front end and the rear end of the battery module 1 are impacted by external force, the first buffer component 2 and the second buffer component 3 are collapsed and absorb energy, so that the impact strength of the battery module 1 is reduced; when the left and right ends of the battery module 1 are impacted by external force, the buffer plates 4 absorb energy elastically, thereby reducing the impact strength of the battery module 1. The power battery module disclosed and exemplified in the embodiment has a good energy absorption effect and good practicability.

As shown in fig. 1-2, the cross section of the buffer member 22 is wavy, and two ends of the buffer member 22 are respectively welded to the baffle 21 and the mounting plate 23. Specifically, the shock absorbing member 22 having a wavy cross section provides a better energy absorbing effect than the linear shock absorbing member, and prevents the impact force from being directly transmitted to the battery module 1.

As shown in fig. 2, one side of the mounting plate 23 adjacent to the battery module 1 is provided with a protruding strip 231, and the protruding strip 231 is detachably connected to the top plate 11 and the bottom plate 12 through a countersunk head bolt. Specifically, countersunk bolts (not shown) are used to connect the protruding strips 231 with the top plate 11 and the bottom plate 12, so as to prevent the bolts from protruding out of the top plate 11 and the bottom plate 12, and ensure the flat surfaces of the top plate 11 and the bottom plate 12.

As shown in fig. 1, the buffer plate 4 is made of spring steel, and both ends of the buffer plate 4 are respectively abutted against the mounting plates 23.

As shown in fig. 1, polypropylene foam is filled between every two of the buffers 22, and the first buffer assembly 2 and the second buffer assembly 3 are made of aluminum alloy. Specifically, polypropylene foam (not shown in the figure) is added between the buffer members 22, so that the overall energy absorption effect of the buffer members 22 is improved, and the first buffer assembly 2 and the second buffer assembly 3 made of aluminum alloy have certain flexibility and are easier to deform and absorb energy under the action of external force.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
