Description

Technical Field

[0001] This utility model belongs to the technical field of energy storage power system, and in particular relates to a BMS component fixing structure suitable for the module PACK of energy storage power system. Background Technology

[0002] Energy storage power systems refer to systems that store electrical energy through media such as batteries and release it when needed, realizing the time transfer and balance of energy. They are commonly used in residential and commercial energy storage, grid peak shaving and frequency regulation, and emergency backup power. A module PACK is a standardized battery pack formed by integrating multiple individual batteries through series and parallel connection and adding structural frames, heat dissipation components, wiring harnesses, etc. A BMS is a battery management system, which is a key device used to control, monitor and protect batteries. In order to monitor and protect the battery pack, the BMS is installed on the PACK through a fixed structure.

[0003] A search revealed CN213184479U, filed on October 27, 2020, which discloses a BMS component fixing structure in a home energy storage battery module PACK. The structure includes multiple component housings, each consisting of a housing body, a housing, a BMS component, and supporting components. The BMS component includes: a BMS control board, a heat sink, a silicone thermally conductive insulating sheet, a BMS power board, a first support column, a silicone thermally conductive insulating sheet, a supporting heat sink, and a second support column. The top and bottom of the right side wall of the BMS power board are horizontally connected to the first support column. The end of the first support column facing away from the BMS power board is connected to the BMS control board. The middle of the right side wall of the BMS power board is connected to the silicone thermally conductive insulating sheet. The side of the silicone thermally conductive insulating sheet facing away from the BMS power board is connected to the heat sink. The left side wall of the BMS power board is connected to the silicone thermally conductive insulating sheet. The side of the silicone thermally conductive insulating sheet facing away from the BMS power board is connected to the supporting heat sink. This product has a single-phase modular structure, making it easy to fix and maintain.

[0004] However, it still has the following drawbacks in practical use:

[0005] In existing module PACKs for energy storage power systems, the BMS component fixing structure involves bolting the BMS control board during use. This method is cumbersome, time-consuming, and labor-intensive for operators, resulting in low work efficiency.

[0006] 2. Existing BMS component mounting structures in energy storage power system module PACKs use mounting bolts through corresponding mounting holes. However, this method requires precise adjustment of the mounting hole positions, which is time-consuming, labor-intensive, and limits the range of installation locations. Therefore, we provide a BMS component mounting structure for energy storage power system module PACKs to solve the aforementioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a BMS component fixing structure suitable for the module PACK of energy storage power system. By setting the mounting components, it is convenient for staff to quickly disassemble and assemble the control board, saving time and effort and increasing work efficiency. In addition, by using screws and nuts, and according to the position of the mounting plate and mounting hole, the connector is installed in a suitable position of the strip hole, expanding the adjustable range of the installation position.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a BMS component fixing structure applicable to the module PACK of an energy storage power system, including a frame and mounting plates installed on the top and bottom of its front face. A support plate is provided on the outer wall of the mounting plate, and a connecting seat is provided at each of the four corners of the support plate. A support plate is fixed in the middle of the adjacent outer wall of the connecting seat. A T-slot is provided inside the connecting seat, and a screw is installed in the through hole on the support plate. An installation component is provided inside the T-slot.

[0010] The mounting components include a push plate located at one end of the outer side of the connector, and a connecting column fixed in the middle of the inner wall of the push plate.

[0011] The present invention is further configured such that a battery pack is provided inside the frame, and mounting holes are provided at both ends of the outer wall of the mounting plate.

[0012] The present invention is further configured such that strip holes are provided at the corners of the outer wall of the support plate, and screws are connected to nuts by passing through the through holes and adjacent strip holes on the support plate in sequence. A control plate is installed on the outer wall of the support plate.

[0013] The present invention is further configured such that the other end of the connecting column passes through the through hole on the outer wall of the T-slot and is connected to the movable plate, and a connecting rod is fixed at the center of one side wall of the movable plate.

[0014] The present invention is further configured such that the other end of the connecting rod slides through the sliding hole in the fixed plate and connects with the card plate, and a spring is sleeved on the outer wall of the connecting rod.

[0015] The present invention is further configured such that the spring is located between the movable plate and the fixed plate, and the outer wall of the fixed plate is fixed on the inner wall of the T-slot.

[0016] This utility model has the following beneficial effects:

[0017] This invention, by setting up an installation component, adjusts the position of the clamping plate under the elastic action of a spring, thereby achieving or releasing the limiting effect between the clamping plate and the mounting hole. This facilitates the subsequent quick disassembly and assembly of the control board by the operator, saving time and effort and increasing work efficiency. It solves the problem that the existing BMS component fixing structure in the module PACK of energy storage power systems uses bolts to install the BMS control board, which is cumbersome, time-consuming, and labor-intensive for operators, resulting in low work efficiency.

[0018] This invention expands the adjustable range of the installation position by setting screws, which cooperate with nuts and, according to the position of the mounting plate and mounting holes, install the connector at a suitable position in the strip hole. This solves the problem that the existing BMS component fixing structure in the module PACK of energy storage power systems requires precise adjustment of the position of each mounting hole, which is time-consuming and labor-intensive, and the installation position range is limited.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0029] Please see Figures 1 to 5 This utility model is a BMS component fixing structure applicable to the module PACK of an energy storage power system, including a frame 100 and a mounting plate 102 installed on the top and bottom of its front end face. A support plate 103 is provided on the outer wall of the mounting plate 102. A connecting seat 104 is provided at each of the four corners of the support plate 103. A support plate 104a is fixed in the middle of the adjacent outer wall of the connecting seat 104. A T-slot 104b is provided inside the connecting seat 104. A screw 200 is installed in the through hole on the support plate 104a.

[0030] Specifically, a battery pack 101 is provided inside the frame 100, and mounting holes 102a are provided at both ends of the outer wall of the mounting plate 102; strip holes 103a are provided at the corners of the outer wall of the support plate 103, and screws 200 pass through the through holes on the support plate 104a and the adjacent strip holes 103a in sequence to connect with nuts, and a control plate 105 is installed on the outer wall of the support plate 103.

[0031] Furthermore, the frame 100, battery pack 101, control board 105, etc. are all existing technologies, so they will not be described in detail here. The screw 200 and nut are used to install the connector 104, and the strip hole 103a allows the screw 200 to pass through and be installed.

[0032] The operation process of this embodiment is as follows: When it is necessary to fix the control board 105 on the battery pack 101, first place the four connecting seats 104 in sequence at the four corners of the support plate 103, and align the mounting components 300 in the connecting seats 104 with the mounting holes 102a on the mounting plate 102. Then, fix the support plate 104a on the connecting seats 104 in the adjacent strip holes 103a by screws 200 and nuts. Then, install the connecting seats 104 on the support plate 103 by the mounting components 300. The design of the strip holes 103a allows the position of the connecting seats 104 to be adjusted according to the position of the mounting plate 102 and the mounting holes 102a, increasing the adjustable range of the mounting position of the connecting seats 104 on the support plate 103, thereby indirectly expanding the adaptability of the mounting components 300 to the mounting plate 102. Example 2

[0033] Please see Figure 5 and Figure 6 Based on Embodiment 1, unlike the first embodiment, an installation component 300 is provided. The installation component 300 includes a push plate 301 disposed at one end of the outer side of the connecting seat 104, and a connecting column 302 fixed in the middle of the inner wall of the push plate 301. This solves the problem that the existing BMS component fixing structure in the module PACK of the energy storage power system is installed by mounting bolts through corresponding mounting holes. However, this method requires precise adjustment of the position of each mounting hole, which is time-consuming and labor-intensive, and the installation position range is limited.

[0034] Specifically, the other end of the connecting column 302 passes through the through hole on the outer wall of the T-slot 104b and is connected to the movable plate 303. A connecting rod 304 is fixed at the center of one side wall of the movable plate 303. The other end of the connecting rod 304 slides through the sliding hole on the fixed plate 305 and is connected to the clamping plate 306. A spring 304a is sleeved on the outer wall of the connecting rod 304. The spring 304a is located between the movable plate 303 and the fixed plate 305. The outer wall of the fixed plate 305 is fixed on the inner wall of the T-slot 104b.

[0035] Furthermore, the push plate 301 and the moving plate 303 are connected by the connecting column 302, and the moving plate 303 and the clamping plate 306 are connected by the connecting rod 304, which serves as a connection and transmission mechanism. The clamping plate 306 is L-shaped and arc-shaped, which can fit the inner wall of the mounting hole 102a. Under the elastic action of the spring 304a, the clamping plate 306 can be moved.

[0036] The operation process in this embodiment is as follows: After the connecting seat 104 is installed on the support plate 103, the control plate 105 needs to be installed on the outer wall of the frame 100. At this time, the push plates 301 on both sides are pushed towards the center. The inner wall of the push plate 301 is connected to the moving plate 303 through the connecting column 302. Therefore, the movement of the push plate 301 will move the moving plate 303 under the action of the connecting column 302. The outer wall of the moving plate 303 is connected to the clamping plate 306 through the connecting rod 304. Therefore, the movement of the moving plate 303 will be carried by the connecting rod. 304 moves along with the clamping plate 306 and compresses the spring 304a. At this time, the clamping plates 306 on both sides move towards the center and are then inserted into the corresponding mounting holes 102a. Then, the force applied to the push plate 301 is stopped. At this time, under the elastic action of the spring 304a, the clamping plates 306 are popped outward, so that the clamping plates 306 are locked in the mounting holes 102a, completing the installation of the control board 105. The same principle applies to disassembly, which facilitates the quick disassembly and assembly of the control board 105 by the staff, saving time and effort and increasing work efficiency.
