Description

Technical Field

[0001] The utility model relates to the technical field of battery protection structures, in particular to an insulation protection structure in a battery box. Background Art

[0002] The car battery box is an important part of electric vehicles. It carries the power battery and plays a role in protecting the power battery. For pure electric vehicles, the power battery provides power for the entire vehicle, and its performance has a huge impact on the performance of the entire vehicle. One of the core components of electric vehicles is the battery box, which stores electrical energy and provides power for the vehicle. The battery pack box material should have the characteristics of electrical insulation, high heat dissipation and chemical stability. Since most car battery boxes are equipped with multiple battery cells, in order to maintain the stability of the battery cells, the battery box should also be equipped with a protective structure that can limit the movement of each battery cell and has safe insulation characteristics.

[0003] Most of the existing insulation protection structures used in the battery box adopt a frame-type anti-collision structure to lock the positions of multiple battery cells. However, during the wiring operation of each battery cell, the line needs to avoid the protection structure, which easily affects the orderliness of the wiring. At the same time, the protection structure cannot fix the line, and the stability of the line cannot be guaranteed during the driving of the car, which is not conducive to the subsequent maintenance and replacement of the line. Utility Model Content

[0004] In response to the above problems, the present application provides an insulation protection structure inside a battery box.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an insulating protection structure inside a battery box, comprising a plurality of insulating partitions arranged in parallel, wherein the upper and lower ends of the insulating partitions are provided with support plates, and the support plates are provided with a pair of linked pressure plates with adjustable heights and spacings between themselves and the support plates, and the pair of linked pressure plates located on the same horizontal plane are connected by a limit bar that can be opened and closed. In a natural state, the limit bar is in a closed state, and the interlayer space formed by the limit bar and the support plate can accommodate the passage of circuits, and a plurality of pressure blocks that can separate the circuits are provided on the side of the limit bar facing the support plate.

[0006] Furthermore, one of the linked pressure plates located on the same horizontal plane is connected to the limit bar through a rotating shaft, and the movable end of the limit bar and the surface of the other linked pressure plate are provided with magnetic strips. When the limit bar is in a closed state, the two magnetic strips are magnetically adsorbed.

[0007] Furthermore, a positioning block 1 is provided on the side of the linkage pressure plate facing the support plate, and a positioning block 2 corresponding to the positioning block 1 is provided on the support plate. The positioning block 1 and the positioning block 2 are connected by a pressure spring. When the linkage pressure plate moves, the positioning block 1 pulls the pressure spring to move.

[0008] Furthermore, the first positioning block is provided with an extension column, and the second positioning block is provided with an alignment sleeve surrounding the outer side of the extension column;

[0009] The extension column is provided with an anti-slipping strip that can move synchronously therewith, and the alignment sleeve is provided with a channel that can accommodate the movement of the anti-slipping strip. When the extension column and the anti-slipping strip move synchronously, the channel can limit the moving stroke of the anti-slipping strip.

[0010] Furthermore, both ends of the support plate are provided with mounting feet, and the upper and lower corresponding mounting feet are connected by a connecting column. The connecting column is also provided with two insulating cover plates arranged from top to bottom, and the insulating cover plates are both in contact with the mounting feet.

[0011] Furthermore, brackets are provided on opposite sides of the two insulating cover plates, and the brackets distributed from top to bottom are all in the same horizontal plane with the support plate.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] In the utility model, the connection lines between the battery cells can pass through the interlayer space formed by the limit strip and the support plate, so that the insulating protection structure leaves space for the lines to pass smoothly. In addition, the lines can be classified and organized, and gaps are left between multiple lines. During the process of repairing and replacing lines, the staff can clearly identify the position of the lines. The limit strip that can be opened and closed is convenient for inserting and removing the lines, so as to facilitate the wiring operation. The position of the line can be quickly adjusted without opening the limit strip, reducing the inconvenience of the adjustment operation caused by the wiring error. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 The insulating protection structure in a battery box shown in the figure includes a plurality of insulating partitions 1 arranged in parallel, and a support plate 2 is provided at the upper and lower ends of the insulating partition 1, and a pair of linkage pressing plates 3 whose height and spacing with the support plate 2 can be adjusted are provided on the support plate 2, and the pair of linkage pressing plates 3 located on the same horizontal plane are connected by a limit bar 4 that can be opened and closed. In the natural state, the limit bar 4 is in a closed state, and the connection lines between each battery cell can pass through the interlayer space formed by the limit bar 4 and the support plate 2, so that the insulating protection structure leaves space for the lines to pass smoothly, and the side of the limit bar 4 facing the support plate 2 is provided with a plurality of pressing blocks 5 that can separate the lines. The pressing blocks 5 are located in the interlayer space, and the lines can be classified and organized, and gaps are left between multiple lines, so that the staff can clearly identify the position of the lines during the process of repairing and replacing the lines.

[0023] One of the linkage pressure plates 3 located on the same horizontal plane is connected to the limit bar 4 through a rotating shaft. The movable end of the limit bar 4 and the surface of the other linkage pressure plate 3 are provided with a magnetic strip 6. When the limit bar 4 is in a closed state, the two magnetic strips 6 are magnetically adsorbed. When the limit bar 4 is opened, the interlayer space formed by it and the support plate 2 is opened, and the line can be smoothly inserted and removed, so as to facilitate the wiring operation. When the limit bar 4 is in a closed state, the pressure block 5 is stuck on the outside of the line, which can achieve the purpose of quickly regularizing the line, leaving space for the line to pass through, so as to facilitate the maintenance and replacement of the line.

[0024] The linkage pressure plate 3 is provided with a positioning block 1 7 on one side facing the support plate 2, and the support plate 2 is provided with a positioning block 2 8 corresponding to the positioning block 1 7. The positioning block 1 7 and the positioning block 2 8 are connected by a pressure spring 9. When the linkage pressure plate 3 moves, the positioning block 1 7 pulls the pressure spring 9 to move. The linkage pressure plate 3 and the limit bar 4 can adjust the distance between themselves and the support plate 2. The position of the line can be quickly adjusted without opening the limit bar 4. The line reaches the pressure block 5 at different positions, which has the advantage of flexible adjustment of the line, reduces the inconvenience of adjustment operation caused by wiring error, and improves the portability of operation.

[0025] When the position adjustment operation of the line is completed, the linkage pressure plate 3 and the limit bar 4 are reset. Under the connecting action of the pressure spring 9, a stable interlayer space is formed again between the limit bar 4 and the support plate 2, and the pressure block 5 is stuck on the outside of the line again to maintain the stability of the line.

[0026] like Figure 3 , Figure 4 As shown, the positioning block 1 7 is provided with an extension column 71, and the positioning block 2 8 is provided with an alignment sleeve 81 surrounding the outer side of the extension column 71. The extension column 71 is provided with an anti-slipping strip 72 that can move synchronously therewith, and the alignment sleeve 81 is provided with a channel that can accommodate the movement of the anti-slipping strip 72. When the extension column 71 and the anti-slipping strip 72 move synchronously, the channel can limit the movement stroke of the anti-slipping strip 72. The extension column 71 can be prevented from being separated from the alignment sleeve 81, further ensuring that the linkage pressure plate 3 can move along a straight line trajectory, avoiding the linkage pressure plate 3 and the limit strip 4 from being offset due to excessive movement, so as to achieve the purpose of the linkage pressure plate 3 and the limit strip 4 being able to return to their positions accurately after movement.

[0027] like Figure 1 As shown, in order to maintain the stability of the multiple insulating baffles 1, mounting feet 10 are provided at both ends of the support plate 2, and the upper and lower corresponding mounting feet 10 are connected by a connecting column 11. The connecting column 11 is also provided with two insulating cover plates 12 arranged from top to bottom, and the insulating cover plates 12 are both fitted with the mounting feet 10. In a natural state, the two insulating cover plates 12 cover the upper and lower parts of the multiple battery cells 1 respectively, and connect the multiple insulating baffles 1.

[0028] like Figure 1 , Figure 4 As shown, in order to prevent the battery cells from squeezing the circuits on the inner side of the insulating cover plate 12 and affecting the arrangement of the circuits, a gap for installing the circuits is left, and brackets 13 are provided on the opposite sides of the two insulating cover plates 12. The brackets 13 distributed from top to bottom are all on the same horizontal plane as the support plate 2. The brackets 13 are pressed against the surface of the battery cells to maintain the stability of the battery cells in the interlayer space formed by the insulating partition 1.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
