[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a general - type high - voltage box BMS installation structure, Figure 1 It shows a schematic diagram of the general - type high - voltage box BMS installation structure in the embodiment of the present utility model, Figure 1 wherein, the installation structure includes a rod body 1 and a plate body 2. A plurality of installation holes 3 are axially formed in the side wall of the rod body 1. Corresponding to the installation holes 3, positioning holes 4 are formed on the plate body 2. The plate body 2 is bolt - assembled with the rod body 1 through the positioning holes 4 and the corresponding installation holes 3, so that the top surface of the rod body 1 is flush with the top surface of the plate body 2. And a limiting hole 5 for installing the BMS battery system 9 is also formed on the plate body 2.

[0025] In this application, both the rod body 1 and the plate body 2 can be produced as standard parts. A plurality of installation holes 3 arranged in a linear array are axially formed in the side wall of a single rod body 1, so that a single rod body 1 can be applicable to installing various plate bodies 2 of different specifications, meeting the installation and fixing requirements for BMS battery systems 9 of different specifications. A plurality of limiting holes 5 arranged in an array are formed on the plate body 2, and BMS battery systems 9 of different specifications can be installed within a certain range, improving the applicable range of a single - specification plate body 2. The design that the BMS battery system 9 can be installed on both sides of the plate body 2 improves the convenience of using the installation structure.

[0026] Reference Figure 2, specifically, the length of the rod body 1 is greater than the length of the longest side of the plate body 2. On the basis of using a single rod body 1, by increasing the length of the rod body 1, the number of mounting holes 3 arranged on the side wall of the rod body 1 is increased to ensure that the length of a single rod body 1 is greater than the lengths of all plate bodies 2 that can be adaptively installed, so that a single rod body 1 can be used for assembling with plate bodies 2 of different specifications, thereby meeting the requirement that BMS battery systems 9 of different specifications and sizes can be installed on a single rod body 1.

[0027] Among them, the several mounting holes 3 are arranged in a linear array on the side wall of the rod body 1, so that the distance between adjacent mounting holes 3 remains consistent. During the production and processing of the rod body 1, the distance between adjacent mounting holes 3 can be designed according to specific unit variables, so that the several mounting holes 3 all have positioning points with standard scales, meeting the data requirements for processing the rod body 1 as a standard part in this application.

[0028] Correspondingly, in order to meet the convenience of routing and leading out wires in the high-voltage box 8, a notch 7 vertically penetrating the side wall of the rod body 1 is provided on the rod body 1. After the rod body 1 is installed in the high-voltage box 8, the wire harness can be routed through the notch 7 or beside the rod body 1; for the wire harness routed through the notch 7, the trouble of winding the wire is saved, and the regularity of the overall layout of the wire harness is improved.

[0029] Reference Figure 3 , specifically, a number of limiting holes 5 are symmetrically arranged on the left and right sides of the plate body 2, and the several limiting holes 5 are arranged in an array. When the BMS battery system 9 is installed on the side wall of the plate body 2, the required ones for bolt connection with the BMS battery system 9 are respectively selected on the left and right sides. In the case of using a single-specification plate body 2, different limiting holes 5 can be selected on the left and right sides to obtain different distances between the limiting holes 5, so that the plate body 2 can install BMS battery systems 9 of different specifications within a certain range, improving the applicable range of a single-specification plate body 2.

[0030] In order to further improve the integrity of the plate body 2 and the rod body 1, at least two positioning holes 4 are provided on the plate surface of the plate body 2, and the positioning holes 4 on the plate surface of the plate body 2 are arranged symmetrically left and right. On the basis that the top end surface of the rod body 1 is flush with the top end surface of the plate body 2, through the positioning holes 4 arranged symmetrically left and right, the firmness of the connection between the plate body 2 and the side wall of the rod body 1 can be ensured.

[0031] Reference Figure 3 , in this embodiment, the plate body 2 specifically includes a plate surface portion 21 and a bending portion 22. One end side wall of the plate surface portion 21 is connected to the side wall of the rod body 1, and one end of the plate surface portion 21 far from the rod body 1 is connected to the bending portion 22, and the bending portion 22 is arranged perpendicular to the plate surface portion 21.

[0032] During the installation process, the rod body 1 is connected to the inner side wall of the high-voltage box 8, and a predetermined distance is reserved between the rod body 1 and the inner bottom surface of the high-voltage box 8. Then, the plate body 2 is bolted to the side wall of the rod body 1, so that the side surface of the plate body 2 is perpendicular to the inner bottom surface of the high-voltage box 8, and the lower end of the plate body 2 abuts against the inner bottom surface of the high-voltage box 8. On this basis, when the plate body 2 is installed on the rod body 1 in the high-voltage box 8, the lower bottom surface of the bent portion 22 abuts against the inner bottom surface of the high-voltage box 8. When the lower bottom surface of the bent portion 22 is in close contact with the inner bottom surface of the high-voltage box 8, the user can directly determine that the side surface of the plate surface portion 21 is perpendicular to the inner bottom surface of the high-voltage box 8 according to this state, improving the convenience of the user during the installation process of the rod body 1 and the plate body 2.

[0033] Specifically, the bent portion 22 and the rod body 1 are respectively arranged on both sides of the plate surface portion 21, and a fixing hole 6 is provided on the bent portion 22. During the installation process of the plate body 2, the plate body 2 is first bolt-assembled with the rod body 1 through the positioning hole 4 and the corresponding installation hole 3, and then the plate body 2 is bolt-connected to the inner bottom of the high-voltage box 8 through the fixing hole 6. The bent portion 22 and the rod body 1 are respectively arranged on different side surfaces of the plate surface portion 21, directly avoiding the overlap of the rod body 1 and the bent portion 22 in the vertical direction. The user can use the device directly above the bent portion 22 to rotate the bolt passing through the fixing hole 6, and at the same time, the operation space will not be blocked by the rod body 1, ensuring the convenience of the installation structure during the installation process.

[0034] Specifically, two bent portions 22 are connected to one end of the plate surface portion 21 away from the rod body 1, and the two bent portions 22 are arranged symmetrically left and right on the same side wall of the plate surface portion 21. When the BMS battery system 9 is installed on the plate body 2, the installation position of the BMS battery system 9 is between the fixing holes 6 on the two bent portions 22. Through the two symmetrically arranged bent portions 22, the fixing holes 6 for bolt installation of the bent portions 22 and the inner bottom of the high-voltage box 8 are respectively arranged on the left and right sides of the BMS battery system 9, so that the fixing holes 6 and the BMS battery system 9 are misaligned in the vertical direction, avoiding the BMS battery system 9 from affecting the operation space for the device to rotate the bolt passing through the fixing hole 6.

[0035] During the actual use process of the installation structure of the present application, the staff can, according to the actual assembly situation of the high-voltage box 8 and the BMS battery system 9, after the rod body 1 is installed on the inner side wall of the high-voltage box 8, refer to Figure 4 , the common installation method is to install the BMS battery system 9 on the side of the plate body 2 facing away from the rod body 1. And a notch 7 vertically penetrating the side wall of the rod body 1 is provided on the rod body 1 of the present application, and the surface of the notch 7 is perpendicular to the side wall of the plate body 2. Therefore, refer to Figure 5The staff can also optionally install the BMS battery system 9 on the side of the plate body 2 facing the rod body 1, so that the BMS battery system 9 is located between the plate body 2 and the inner wall of the high-voltage box 8 connected to the side wall of the rod body 1, and is surrounded by the rod body 1, the plate body 2 and the inner wall of the high-voltage box 8. The connecting wire harness used to connect to the BMS battery system 9 can be led out through the notch 7 to the outside of the high-voltage box 8, which can further improve the protection of the BMS battery system 9.

[0036] Meanwhile, referring to Figure 6 for some special high-voltage boxes 8, the staff can also install the required BMS battery system 9 on both the side of the plate body 2 facing the rod body 1 and the side of the plate body 2 facing away from the rod body 1, further releasing the internal space of the high-voltage box 8, which is beneficial to the layout inside the high-voltage box 8 and the application of the installation structure.

[0037] Referring to Figure 7 In the actual use process of the installation structure of the present application, the rod body 1 can be first installed on the inner side wall of the high-voltage box 8 by welding or bolt connection, etc., and several mounting holes 3 on the rod body 1 face the inside of the high-voltage box 8. According to the size of different specifications of the BMS battery system 9, a plate body 2 that can be adapted for use is selected. During the process of selecting the plate body 2, since several limit holes 5 are arranged in an array on the plate body 2, there are several limit holes 5 with different spacings on the plate body 2. When the variation range of the length and width values of the BMS battery system 9 is within a certain range, the installation position of the BMS battery system 9 can be adjusted and fixedly installed according to the limit holes 5 first, and then the plate body 2 is bolted to the side wall of the rod body 1.

[0038] When the length and width values of the BMS battery system 9 exceed the length and width values of the installation surface of the selected plate body 2, the size specification of the plate body 2 can be replaced. On the basis that several mounting holes 3 are arranged in a linear array on the side wall of the rod body 1, the positioning holes 4 on different specification plate bodies 2 can all find mounting holes 3 on the side wall of the rod body 1 that can be bolted correspondingly, so that various plate bodies 2 with different specification sizes can be adapted and assembled with the side wall of a single rod body 1.

[0039] Meanwhile, according to the actual layout of the internal space of the high-voltage box 8, the BMS battery system 9 is selectively installed on the side of the plate body 2 facing the rod body 1 or the side facing away from the rod body 1, or the BMS battery system 9 can be installed on both sides of the plate body 2, so that the BMS battery system 9 is vertically placed in the high-voltage box 8; the rod body 1 can also be directly installed on the inner bottom surface of the high-voltage box 8, so that the side surface of the plate body 2 installed on the side wall of the rod body 1 is parallel to the inner bottom surface of the high-voltage box 8. Similarly, the BMS battery system 9 can be installed above or below the plate body 2, or installed on both the upper and lower surfaces of the plate body 2. At this time, the bent portion 22 can be abutted against the inner side wall of the high-voltage box 8, and the bent portion 22 and the high-voltage box 8 are fixed by bolts. The bent portion 22 passes through the position above the rod body 1, and sufficient installation operation space can also be obtained in the high-voltage box 8.

[0040] During later maintenance, there is no need to remove the rod body 1. The plate body 2 can be directly removed from the side wall of the rod body 1 and the high-voltage box 8 by bolts for the inspection or replacement of the BMS battery system 9; secondly, the fixing method of the present application is connected and fixed by bolts, but in actual use, the fixing method also includes, but is not limited to, pins and buckles.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
