For example, the connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In the present invention, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined based on the inside and outside of the corresponding parts. In addition, "facing" and "backward" are defined based on the direction in which the plug-in 2 is used, and "axial" is defined based on the arrangement direction of the limit hole 22 in the present invention. Specifically, in the drawings provided by the present invention, the orientation or position relationship used is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The orientation terms of the present invention should be understood in conjunction with the actual installation state.

[0052] See also Figure 1 , Figure 3 as well as Fig.16 The first aspect of the utility model provides a connector, which includes a plug-in 2 and two oppositely arranged fixing members 1, wherein a protrusion 11 is formed on the fixing member 1, and a groove 21 is formed on the plug-in, and the protrusion 11 is suitable for abutting against the groove 21. The utility model can fix two fixing members 1 together through a plug-in 2, specifically, as Figure 1 and Fig.13 As shown, when in use, the two fixing members 1 are arranged up and down, and then the plug-in 2 is inserted, and the two fixing members 1 are fixedly connected together by the abutment between the protrusion 11 and the groove portion 21. Because the protrusion 11 and the groove portion 21 are subjected to mutual force, they can be locked with each other, thereby forming a connection structure with a simple structure and capable of achieving quick connection.

[0053] Further, see Figure 1 As a specific implementation of the utility model, a card slot is formed on the fixing member, and two adjacent card slots are surrounded to form a receiving space, and the receiving space can be used for the plug-in 2 to be inserted. The receiving space can surround the plug-in 2 inside to prevent the plug-in 2 from detaching.

[0054] Furthermore, in order to better form a locking relationship between the fixing member 1 and the plug-in unit 2 , the present invention is further provided with a locking mechanism 3 , which can form a locking relationship between the plug-in unit 2 and the fixing member 1 .

[0055] Specifically, when the fixing member 1 is not provided with a card slot, the locking mechanism 3 is disposed between the protruding portion 11 and the recessed portion 21. It should be noted that a locking mechanism may be provided corresponding to each protruding portion 11. When the fixing member 1 is provided with a card slot, when the plug-in 2 is inserted into a preset position in the accommodation space, the locking mechanism can lock the plug-in 2 with the fixing member 1.

[0056] The utility model has a simple structure and can be quickly installed. As a specific implementation of the utility model, a card slot is formed on the fixing member 1 as an example. Figure 3 When in use, first align the two fixing members 1, and then insert the plug-in 2 into the accommodating space formed by the two fixing members 1, wherein the protrusion 11 on each fixing member 1 abuts against the groove 21 on the plug-in 2, so that the two fixing members 1 can limit the movement of the plug-in 2 in a direction perpendicular to the length of the plug-in 2, and then during the movement of the plug-in 2, the locking mechanism 3 is set between the plug-in 2 and the fixing member 1, and when the preset position is reached, the locking mechanism 3 works to lock the plug-in 2 and the fixing member 1, thereby achieving locking in the axial direction.

[0057] It should be noted that the "axial direction" is a direction perpendicular to the mounting surface of the fixing member 1, and can also be understood as being perpendicular to the length and width directions of the plug-in 2. The slots of the two fixing members 1 enclose a receiving space, and the plug-in 2 is inserted. The fixing member 1 can limit the movement of the plug-in 2 in the width direction, and the locking mechanism 3 is provided to limit the movement of the plug-in 2 in the axial direction, so that the plug-in 2 and the fixing member 1 are locked with each other.

[0058] It should also be noted that if Figure 1 and Figure 3 As shown, since two fixing members 1 are provided, the number of fixing members 1 can be selected according to the actual usage when the locking mechanism 3 is provided, such as Figure 3As shown, although there is only one plug-in 2, a locking mechanism 3 is provided for each fixing member 1 to enhance the locking force. Furthermore, for the number of fixing members 1, two is at least two. If the object to be connected is too large, multiple fixing members 1 can be selected, and the number of locking mechanisms 3 and the length of the plug-in 2 can be increased accordingly.

[0059] Further, see Figure 1 , Figure 4 as well as Figure 8 As a specific embodiment of the present invention, the locking mechanism 3 includes an elastic member 31 and a limit block 32. A limit hole 22 is formed on the plug-in 2, and a limit portion 12 is formed on the fixing member 1. When the plug-in 2 reaches the preset position, the limit block 32 will pass through the limit hole 22 and be inserted into the limit portion 12 under the action of the elastic member 31. It can be understood that for the convenience of installation, when in use, the limit block 32 has been installed on the plug-in 2 through the elastic member 31. Specifically, as shown in FIG. Figure 7 and Figure 8 As shown, a hollow structure is formed inside the plug-in 2, and the limit block 32 is installed at the bottom of the plug-in 2 through the elastic member 31, and then the limit hole 22 is set at the top of the plug-in 2. The hollow structure can reduce the dead weight of the plug-in 2. Under the premise of not affecting the structural strength, the existence of the limit hole 22 can provide guidance for the movement of the limit block 32, so that the limit block 32 can pass through the hollow structure of the plug-in 2 and extend from the limit hole 22, and then be inserted into the limit portion 12. After the limit block 32 is inserted into the limit portion 12, it can limit the plug-in 2 from continuing to move along the length direction from the axial direction, thereby forming a lock.

[0060] Specifically, as a specific implementation of the utility model, Figure 1 and Figure 4 As shown, a limiting through hole is preferably used as the limiting portion 12. When in use, the limiting block 32 is inserted into the limiting through hole to limit the position of the plug-in 2 in the accommodating space in the axial direction. When in use, if disassembly is required, the limiting block 32 can also be pressed to make the upper surface of the limiting block 32 lower than the lower end surface of the limiting through hole, and then the plug-in 2 can be moved to achieve disassembly. This embodiment can achieve rapid installation and disassembly.

[0061] More specifically, see Figure 1 , Fig. 9 as well as Fig.10 In order to prevent the slider from extending upward under the action of the elastic member 31 and then extending out of the fixing member 1, which not only affects the limiting strength but also affects the appearance, a limiting protrusion 23 is formed on the limiting hole 22 of the plug-in 2, and a buckle 33 is formed on the slider. When the slider moves along the axial direction of the limiting hole 22, the limiting protrusion 23 abuts against the buckle 33, thereby preventing the slider from continuing to move, and being able to form a balance with the rebound force of the elastic member 31.

[0062] In addition, as other specific embodiments of the present invention, the structural form of the locking mechanism 3 is not limited to the above structure. When the limited position hole 22 is provided on the plug-in 2 and the limited position through hole is formed on the fixing member 1, both holes can be processed into threaded holes, and then bolts can be used for axial locking, which can be positioning pins, and axial locking can be achieved by interference fit. Figure 1 , Figure 6 as well as Figure 7 As shown, a guide protrusion 17 is formed on the fixing member 1, and a guide groove 24 is formed on the plug-in 2. The guide protrusion 17 can match the guide groove 24. When the plug-in 2 is inserted into the fixing member 1, the guide protrusion 17 and the guide groove 24 cooperate with each other to achieve guidance. Fig.13 As shown, when two adjacent fixing members 1 are arranged up and down, the guide protrusion 17 and the guide groove 24 located at the bottom can cooperate with each other to prevent the plug-in 2 from moving downward.

[0063] Further, as a specific implementation of the present invention, see Figure 1 and Figure 3 As a specific embodiment of the present utility model, the fixing member 1 includes a clamping portion 13 and a fixing base plate 14. Specifically, the protrusion 11 and the guide protrusion 17 are formed on the clamping portion 13, and a reinforcing rib 16 is formed between the fixing base plate 14 and the clamping portion 13 to enhance the structural strength. It should be noted that, if Figure 1 and Figure 3 As shown, the reinforcing rib 16 is disposed on the outer wall of the clamping portion 13 and will not affect the formation of the internal clamping groove.

[0064] Furthermore, a plurality of protruding teeth 15 are evenly arranged on the fixed base plate 14 to form a reinforcement structure on the fixed base plate 14. The plurality of protruding teeth 15 are transformed into a plurality of force points in contact with the plug-in 2, which can balance the force while strengthening the structural strength of the fixed base plate 14 and reduce the deadweight of the fixed base plate 14.

[0065] In addition, as a preferred embodiment of the present invention, the elastic member 31 may be a spring. The spring has good resilience and can help the slider to move well.

[0066] The connecting piece provided in the first aspect of the utility model has a simple structure, is convenient to install and disassemble, and can also ensure the connection strength.

[0067] It should be noted that, for the structural form of the fixing member 1 and the plug-in 2, such as Figure 1This is only a specific implementation method. When in use, the structure can be set as needed, as long as the protrusions 11 on the two fixing members 1 can form a snap connection with the grooves on the plug-in 2. Furthermore, the practical locking mechanism 3 can lock the fixing member 1 and the plug-in 2.

[0068] It should also be noted that both the fixing member 1 and the plug-in 2 can be supported by aluminum extrusion technology, and the limit block 32 can be made of plastic. The fixing member 1 and the plug-in 2 processed by aluminum extrusion technology have high structural strength and are durable, which can increase the service life. The plastic part has a certain deformation ability and can fit with the inside of the limit hole 22 and the limit through hole when in use, avoiding the displacement of the limit block 32 due to the existence of a gap, which affects the locking effect.

[0069] The second aspect of the present invention provides an energy storage device, comprising a plurality of energy storage boxes 4 and the connecting piece provided in the first aspect, wherein the connecting piece is used to connect two adjacent energy storage boxes.

[0070] Specifically, as a specific implementation of the present utility model, see Figure 2 , Fig.11 , Fig.12 as well as Fig.16 , and also includes a plurality of energy storage boxes 4, wherein the fixing member 1 is installed on the outer wall of the energy storage box 4, such as Figure 4 As shown, a mounting hole 18 is formed on the fixing member 1, and the fixing member 1 can be mounted on the energy storage box 4 by mounting bolts 41, and then the fixing members 1 of two adjacent energy storage boxes 4 are combined to form a receiving space, the plug-in 2 is inserted into the receiving space, and the fixing member 1 and the plug-in 2 are locked by the locking mechanism 3. The structure of the connector is simple, and different from the existing connector, the connector has a greater connection strength, is easy to install, and is also convenient to disassemble.

[0071] In addition, as another specific implementation of the energy storage device provided by the utility model, see Fig.14 and Fig.15 In order to further save space, the connecting piece can be arranged between two adjacent energy storage boxes 4 without affecting the use of the energy storage box 4, such as Fig.15 As shown, the matching plug-in 2 is then inserted into the space formed by the two adjacent energy storage boxes 4, and locked under the action of the locking mechanism 3. In this way, the appearance of the energy storage device can be made more beautiful. It should be noted that a groove capable of accommodating the fixing member 1 can be provided on the opposite working surfaces of the two adjacent energy storage boxes 4, and the fixing member 1 can be installed in the groove, or the fixing member 1 and the energy storage box 4 can be provided as an integrally formed part.
