Abstract

The utility model discloses an independent opening structure of a high-voltage device. The independent opening structure comprises a battery pack, wherein an upper cover for integrally covering is arranged at the upper part of the battery pack; and the upper cover is provided with an opening and a high-voltage cover for covering the opening at the parts corresponding to the high-voltage device and a BMS (Battery Management System) in the battery pack. The independent opening structure has the advantages that the high-voltage cover for covering the high-voltage device and the BMS is attached above the upper cover of the whole battery pack; targeted later maintenance can be easily achieved by an independent opening way of the high-voltage cover or an integral opening way of the whole cover, so that the working efficiency can be conveniently improved, and the safety and the convenience of the later maintenance can be greatly improved.

Description

A kind of high tension apparatus independence Unclosing structure

Technical field

The utility model is related to a kind of high pressure assembling device Unclosing structure, in particular, and the utility model is related to the high tension apparatus Unclosing structure for electrokinetic cell bag a kind of easy to maintenance and safe and reliable.

Background technology

Because lithium ion battery has, voltage is high, capacity is big, small volume, light weight, the advantages of operating temperature range is wide, therefore Li-ion batteries piles have been widely used in every field, and the especially application in electric vehicle field is even more more and more.

Current battery for electric vehicle bag mostly by the more battery pack string of number and is formed, therefore, the volume of battery bag is larger, and various high tension apparatus and BMS system basic sets are at the certain position in battery bag, and during the maintenance and repair in later stage, problem points are concentrated in high-tension electricity device and BMS systems substantially, therefore are frequently necessary to open lid and are safeguarded.

Existing traditional power battery bag is all to cover the entirety of battery bag by a big upper lid, and such set-up mode has two shortcomings：

（1）Dismounting during to later maintenance is extremely inconvenient；

（2）After entirely upper lid is opened, the exposed of all batteries can bring the unexpected potential safety hazard of generation to maintenance personal.

Utility model content

Problem to be solved in the utility model, exactly overcomes the shortcoming of prior art, and provide high tension apparatus independence Unclosing structure that is a kind of safe and reliable and being easy to later maintenance for this.

High tension apparatus independence Unclosing structure of the present utility model, including battery bag, the top of the battery bag are provided with the overall upper lid of covering, and the position of the upper lid correspondence battery bag inner high voltage device and BMS systems is provided with out that empty and covering is described to open empty high gland.

High tension apparatus independence Unclosing structure of the present utility model, compared with traditional electrokinetic cell pack arrangement, has the advantages that：

（1）Covering high tension apparatus and the high gland of BMS systems are depended on battery bag integral upper cover, and the structure design can be greatly enhanced the security and convenience of later maintenance.

（2）The independent frame mode opened or opened with whole upper lid one of high gland, can easily realize autotelic later maintenance, be easy to improve operating efficiency.

Brief description of the drawings

Fig. 1 is the appearance schematic diagram of battery bag in the utility model.

Fig. 2 is that the battery bag in Fig. 1 opens the schematic diagram after the high gland of covering high tension apparatus and BMS systems.

Fig. 3 is that the battery bag in Fig. 1 opens the schematic diagram for covering overall upper lid.

Fig. 4 is the structural representation of upper lid in Fig. 1 and the high gland being arranged on.

Embodiment

In order that the utility model is easier to be understood, its technical scheme is described in detail below in conjunction with drawings and Examples.

Reference picture 1, Fig. 2, high tension apparatus independence Unclosing structure of the present utility model, including battery bag 1, the top of the battery bag 1 sets the overall upper lid 2 of covering, the position of the corresponding battery bag inner high voltage device of upper lid 2 and BMS systems 4 is provided with out sky, and described sky position of opening is provided with the high gland 3 covered.

Reference picture 3, Fig. 4, the utility model employs the theory for closing the battery parcel 5 in battery bag 1 with high tension apparatus and BMS systems 4 " separating ", autotelic be directed to usually needs the failure problems of the high tension apparatus and BMS systems 4 solved rationally to be set in the described later maintenance of battery bag 1, so, in the later maintenance of the battery bag 1, just overall upper lid 2 is covered without opening, high tension apparatus that the high gland 3 being independently arranged can be covered to it need to only be opened and BMS systems 4 are safeguarded, so as to avoid prior art from making exposed the brought potential safety hazard of all batteries by opening whole upper lid, simultaneously, for later maintenance, not only facilitate dismounting, and shoot the arrow at the target, it is more safe and reliable.

High tension apparatus independence Unclosing structure of the present utility model is schematically described above by reference to drawings and Examples, the description is not restricted.One of ordinary skill in the art will be understood that set-up mode of the present utility model is possible to that some changes occur in actual applications, and other staff may also make similar Design under its enlightenment.It is pointed out that without departing from design aim of the present utility model, all obvious changes and its similar Design are all contained within protection domain of the present utility model.

Claims

1. a kind of high tension apparatus independence Unclosing structure, including battery bag, it is characterized in that, the top of the battery bag is provided with the overall upper lid of covering, the position of the upper lid correspondence battery bag inner high voltage device and BMS systems is provided with out sky, and described vacancy of opening is provided with covering this opens the high gland of sky.
