DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will further describe the present utility model with reference to the attached Figures 1-3 to further illustrate the present utility model.

[0024] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all connection / linkage relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. The various technical features in the creation of the present utility model can be interactively combined without conflicting with each other.

[0025] Referring to Figure 1 , the present utility model provides a connection terminal for an energy storage module, which includes a base 2, a connection nut 4 and an upper cover 1. Among them, the base 2 is the installation base of the entire structure, and is used to carry and install various components and fix connection pieces such as connection rows or connection bars in the battery energy storage system; the connection nut 4 is used to connect the battery pack to the inside of the base 2; the upper cover 1 is arranged on the base 2 to protect the various connection pieces installed and connected to the base 2.

[0026] Referring to Figure 2 , the base 2 includes a bottom plate 21 and side plates 22. There are two side plates 22, and the two side plates 22 are arranged side by side and parallel, and are vertically and fixedly connected to the surface of the bottom plate 21. An installation block 3 is arranged on the bottom plate 21, and the installation block 3 is located between the two side plates 22. Specifically, a connection hole is opened in the middle of the bottom plate 21, and the installation block 3 is fixedly connected to the bottom plate 21 and located in the connection hole. An installation through hole is opened in the installation block 3, and the connection nut 4 is vertically installed in the installation through hole. Since the installation block 3 is arranged in the connection, the connection nut 4 can contact the connection piece above the bottom plate 21 and the bottom plate 21 at this time. When connecting, a screw adapted to the connection nut 4 can be selected to connect and fix the connection nut 4 to the connection piece. The connection is made through the structure of the screw and the nut, with strong reliability and high stability, effectively reducing the possibility of connection loosening, poor contact and other situations occurring during use.

[0027] By arranging the connection nut 4 on the base 2 and arranging the upper cover 1 above the base 2, when connecting with the energy storage module, the connection piece is placed at the connection nut 4, and the connection piece is fixed by the cooperation of the screw and the connection nut 4. The fixing method is firm and stable, and has a wide application range and strong flexibility.

[0028] Furthermore, in this embodiment, the connecting nut 4 is a hot-melt nut. The hot-melt nut has extremely strong torsional force and high locking force, making it more stable during installation and connection, and it can also maintain good fastening performance after multiple assemblies and disconnections, not easily loosening, and its installation is simple. In addition, the hot-melt nut is made of copper material, has good electrical conductivity and corrosion resistance, and can effectively ensure the reliability of current transmission of the connection terminals of the energy storage module.

[0029] Referring to Figure 2 and Figure 3 , one side of the upper cover 1 is rotatably connected to one of the side plates 22. Specifically, a rotating shaft 221 is rotatably connected to the side plate 22, and a rotating hole 12 is correspondingly formed on the upper cover 1. The rotating shaft 221 is rotatably connected to the rotating hole 12 to realize the rotational connection of the upper cover 1 to the side plate 22. A fixing member is provided on the other side plate 22, and the fixing member is used to connect and fix the upper cover 1 and the base 2 when the upper cover 1 rotates to completely cover the base 2. The upper cover 1 is located above the bottom plate 21, and when the upper cover 1 completely covers the base 2, there is a spacing between the upper cover 1 and the bottom plate 21, and this spacing is the installation space reserved for the connecting member. In actual setting, the distance between the upper cover 1 and the bottom plate 21 can be set according to the spacing required for installing the connecting member, so as to increase the adaptability of the present invention, enable it to select more connection terminals to be connected, and enhance the flexibility of its application. Setting the upper cover 1 on the mounting seat can protect the connecting nut 4 and the connecting member, effectively reduce potential safety hazards, and improve the safety of the system. Moreover, the upper cover 1 is connected to the mounting seat by a rotational connection method. When installing or disassembling the connecting member, the fixing member is opened and the upper cover 1 is flipped to perform the installation or disassembly work of the connecting member. The structure is simple and the operation is convenient.

[0030] It should be noted that in other embodiments, the upper cover 1 can also be rotatably connected to the side plate 22 through a hinge structure, etc. Therefore, the specific structure of the connection between the upper cover 1 and the side plate 22 is not uniquely limited here, as long as the above effects can be achieved.

[0031] Furthermore, the fixing member is a buckle 222. The buckle 222 is fixedly connected to the other side plate 22, and the buckle 222 is made of a material with certain elasticity. Correspondingly, a buckling portion 11 is provided on one side of the upper cover 1. When the upper cover 1 is flipped to completely cover the base 2, the upper cover 1 is gently pressed, so that the buckle 222 is buckled to the buckling portion 11 to realize the connection and fixation of the upper cover 1 and the base 2. When the upper cover 1 needs to be opened, the buckle 222 is toggled in the direction away from the side plate 22, so that the buckle 222 is disengaged from the buckling portion 11, and at this time, the upper cover 1 can be flipped. The connection and fixation between the upper cover 1 and the base 2 are realized through the buckle 222 structure. The structure is simple, the opening and closing are convenient, and it is beneficial to reduce the operation difficulty.

[0032] Furthermore, in one embodiment, a driving torsion spring 24 is sleeved on the rotating shaft 221, and one side torsion arm of the driving torsion spring 24 abuts against the upper protective cover 1, and the other side torsion arm abuts against the side plate 22 on which the rotating shaft 221 is installed. When the upper protective cover 1 is completely covered on the base 2, the elasticity of the driving torsion spring 24 contracts; when the buckle 222 is separated from the buckle 11, the elasticity of the driving torsion spring 24 is released to drive the upper protective cover 1 to flip, which has a simple structure, is conducive to reducing the difficulty of operation, effectively improves the speed of disassembly and assembly, and is convenient for later maintenance and replacement.

[0033] A plurality of fixing holes 23 are provided around the edges of the bottom plate 21, and fasteners such as set screws can be connected to the fixing holes 23. The bottom plate 21 can be fixed to the end plate of the energy storage module through the fasteners, and then the base 2 can be fixed to the energy storage module. The installation is firm and reliable, and the disassembly and installation are convenient. In this embodiment, the number of fixing holes 23 is 4. The number of fixing holes 23 can be set as needed during actual setting, and is not limited here. The fixing holes 23 are arranged around the bottom plate 21, and the positions of the side plates 22 are staggered, so that the operator can install and fix the base 2 conveniently, and reduce the possibility that the side plates 22 and the upper protective cover 1 interfere with the installation tools when the base 2 is installed on the energy storage module, thereby affecting the installation of the base 2.

[0034] Furthermore, one end of the mounting block 3 facing away from the upper protective cover 1 protrudes out of the base 2, and the connecting wires outside the energy storage module are connected to the side of the connecting nut 4 facing away from the upper protective cover 1 through screws adapted to the connecting nut 4. The mounting block 3 is arranged to protrude, which is convenient for operators to install and fix the external connecting wires, and helps to reduce the difficulty of installation.

[0035] Furthermore, at least one of the two side panels 22 is provided with a handle block 223, and the handle block 223 is located on the side of the side panel 22 facing away from the mounting block 3. The handle block 223 is provided to facilitate the operator to hold the energy storage module connection terminal, and to facilitate the operator to grasp and lock the fasteners when installing the base 2 on the energy storage module. The handle block 223 can also be fixedly connected to the bottom plate 21 at the same time to strengthen the connection strength between the side plate 22 and the bottom plate 21. In addition, in order to strengthen the connection strength between the mounting block 3 and the bottom plate 21, the mounting block 3 is fixedly provided with reinforcing ribs 31 around it, and the reinforcing ribs 31 are fixedly connected to the bottom plate 21.

[0036] The installation process of the utility model is:

[0037] First, open the upper protective cover 1 and fasten the base 2 to the battery box with fasteners such as fastening screws; then, use screws compatible with the connecting nut 4 to connect the battery pack and the connecting nut 4 on the inner side of the base 2; then, use the same screws to connect and fix the external connecting wire to the side of the connecting nut 4 facing away from the upper protective cover 1; finally, turn over and press the upper protective cover 1 so that the buckle 222 is fastened to the buckle part 11, and the installation is completed.
