[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0058] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0059] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time.

[0060] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0061] Energy storage equipment is a device that can store electrical energy and supply power to electronic devices. The structural connection within the energy storage equipment is generally through screws passing through one of the structures and connecting to the screw column on the other structure. At present, the top of the screw column is fixed with a nut through hot melting or beer-in-sleeve process, and the screw column is threadedly connected through the nut and screw at the top to fasten the two structures that need to be connected. It can be understood that when there is a large tensile force between the two structures, the screw can easily pull the nut out of the screw column, causing the nut to fall off, resulting in an unstable connection between the structures. When it is applied to energy storage equipment, it will also affect the reliability of carrying and handling the energy storage equipment.

[0062] To this end, the present application provides a connecting component, a fastening connection structure and an energy storage device, which can ensure the strength of the structure connected between the connecting piece and the connecting component. When the fastening connection structure is applied to the energy storage device, the overall structural strength of the energy storage device can be increased, ensuring the reliability of carrying and transporting the energy storage device.

[0063] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0064] like Figures 1 to 4 As shown, the connecting component 11 provided in the embodiment of the present application is used for fastening connection with the connecting piece 12 , and includes a connecting column 111 and a fastener 112 .

[0065] The connecting column 111 is provided with an annular groove (not shown), and the connecting column 111 has a free end 1111. There is a distance between the annular groove and the free end 1111, and the connecting column 111 is used for the connecting member 12 to be connected to the connecting column 111 from the free end 1111. The fastener 112 is provided in the annular groove, and the fastener 112 is used to be fastened and connected to the connecting column 111, so that the connecting component 11 can be fastened and connected to the connecting member 12.

[0066] It is understandable that there is no limitation on the connection method between the connecting member 12 and the connecting column 111. For example, the connecting member 12 may be inserted into the connecting column 111 from the free end 1111 and fastened with the fastener 112 to achieve the connection with the connecting column 111; or the connecting member 12 may be sleeved on the outside of the connecting column 111 from the free end 1111 and fastened with the fastener 112 to achieve the connection with the connecting column 111.

[0067] It can be understood that the annular groove is a groove body arranged around the axis of the connecting shaft, and it can be located outside the connecting column 111 or inside the connecting column 111. In the present application, the fastener 112 is arranged in the annular groove, and when it is located outside the connecting column 111, it surrounds the connecting column 111, and when it is located inside the connecting column 111, the connecting column 111 surrounds the fastener 112. Therefore, no matter how it is arranged, the fastener 112 is not easy to be separated from the connecting column 111 in the radial direction, and the groove wall of the annular groove can prevent the fastener 112 from being separated from the connecting column 111 in the axial direction, so that the structure of the connecting component 11 can be ensured to be stable and reliable.

[0068] It can be understood that there is a distance between the annular groove and the free end 1111, which means that there is a structure between the groove wall on the side of the annular groove facing the free end 1111 and the free end 1111, and the annular groove will not open on the side of the free end 1111 of the connecting column 111. Therefore, the fastener 112 arranged in the annular groove will also be blocked by the structure between the groove wall on the side of the annular groove facing the free end 1111 and the free end 1111.

[0069] In the connecting component 11 provided in the embodiment of the present application, the connecting member 12 can be fastened and connected from the free end 1111 of the connecting column 111 and the fastener 112 on the connecting column 111 to achieve a fastened connection with the connecting component 11. When the connecting member 12 and / or the connecting component 11 are subjected to external tension, the connecting member 12 will pull the fastener 112 fastened to the connecting member 12. Since the fastener 112 is arranged in the annular groove, the groove wall of the annular groove can support the fastener 112 to prevent the fastener 112 from falling off the connecting column 111, thereby ensuring the strength of the structure connected between the connecting member 12 and the connecting component 11. When the connecting component 11 and the connecting member 12 are applied to the energy storage device, the overall structural strength of the energy storage device can be increased to ensure the reliability of carrying and transporting the energy storage device.

[0070] like Figures 1 to 4 As shown, in some embodiments, the fastener 112 is integrally formed with the connecting column 111. In this way, it can be ensured that the fastener 112 and the connecting column 111 are firmly connected, and further it can be ensured that after the fastener 112 and the connecting member 12 are firmly connected, the constructed fastening connection structure 10 is stable and reliable. For example, the fastener 112 and the connecting column 111 can be integrally formed by hot melting or beer coating. Of course, in other embodiments, the fastener 112 and the connecting column 111 may not be integrally formed, but only fixed to the connecting column 111 by being embedded in the annular groove.

[0071] like Figures 1 to 4As shown, in some embodiments, the fastener 112 includes a fastening nut, and the fastener 112 is used to be threadedly connected to the connector 12. The connector 12 is threadedly connected to the fastener 112, which can facilitate the disassembly and assembly between the two, so as to facilitate the assembly and maintenance of the structure. And through the threaded connection, the stability and reliability of the connector 12 and the fastener 112 after connection can be ensured. In this embodiment, the connector 12 can be provided with an external thread, and the fastener 112 can be provided with an internal thread. The external thread of the connector 12 and the internal thread of the fastener 112 cooperate to achieve a threaded connection, for example, when the fastener 112 is located in the connecting column 111, to achieve a fastened connection with the connector 12; or, the connector 12 can be provided with an internal thread, and the fastener 112 can be provided with an external thread. The internal thread of the connector 12 and the external thread of the fastener 112 cooperate to achieve a threaded connection, for example, when the fastener 112 is located outside the connecting column 111, to achieve a fastened connection with the connector 12. In some other embodiments, the fastener 112 can also be used to snap-connect with the connector 12 to achieve fastening. For example, when the fastener 112 is located inside the connecting column 111, the fastener 112 is provided with a snap-in hole, and a snap-in hook is provided on the peripheral side of the connector 12. The connector 12 extends into the snap-in hole, and the snap-in hook hooks the fastener 112 to prevent the connector 12 from being separated from the fastener 112; or, when the fastener 112 is located outside the connecting column 111, a snap-in hook is provided on the inner side of the connector 12, and the connector 12 is sleeved on the fastener 112, and the snap-in hook hooks the fastener 112 to prevent the connector 12 from being separated from the fastener 112.

[0072] In some embodiments, the fastener 112 includes a metal fastener. The metal fastener can ensure that the fastener 112 has sufficient structural strength, and after it is fastened to the connector 12, it can ensure that the fastened connection is stable and reliable. For example, the fastener 112 is an iron fastener or a copper fastener.

[0073] In addition, the connector 12 also includes a metal connector to ensure that the connector 12 has sufficient structural strength, thereby ensuring a stable and reliable connection with the fastener 112. For example, the connector 12 is an iron connector or a copper connector.

[0074] like Figures 1 to 4 As shown, in some embodiments, the fastener 112 is adapted to the annular groove. After the fastener 112 is placed in the annular groove, it can be firmly embedded in the annular groove by adapting to avoid its displacement relative to the annular groove, ensuring that the fastener 112 is firmly set on the connecting column 111, thereby ensuring that the fastening connection structure 10 is stable and reliable, and the connected structure will not be displaced or shaken. Of course, in some other embodiments, the fastener 112 can also be fixed in the annular groove by a clamping piece on the fastener 112 to ensure that there is no displacement between the two.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments, the connecting column 111 is provided with a connecting hole 111a, and the annular groove is provided in the connecting hole 111a. It should be noted that the connecting hole 111a is open at one side of the free end 1111 of the connecting column 111. In this embodiment, the fastener 112 is placed in the connecting column 111. When the connecting member 12 is fastened to the connecting component 11, the connecting member 12 extends from one side of the free end 1111 of the connecting column 111 into the connecting hole 111a and is fastened to the fastener 112. The connection of the connecting member 12 can be positioned through the connecting hole 111a to facilitate the fastening connection with the connecting component 11.

[0076] Exemplarily, the inner side of the fastener 112 and the circumferential side of the connecting column 111 are threadedly connected to achieve connection and disassembly of the connecting piece 12 and the connecting component 11 .

[0077] In the above embodiment, the fastener 112 includes a circular fastener, and the diameter of the fastener 112 is larger than the aperture of the connecting hole 111a. In this way, it can be ensured that the fastener 112 will not be separated from the connecting column 111 along the connecting hole 111a, and the fastener 112 can be reliably placed in the annular groove. In addition, the circular fastener can also facilitate the fastener 112 to be adapted and assembled in the annular groove. Exemplarily, the fastener 112 and the connecting column 111 are integrally formed to prevent the fastener 112 from rotating relative to the connecting column 111, and ensure that the fastening connection structure 10 formed by the connecting member 12 after being connected to the fastener 112 is stable and reliable.

[0078] Of course, the fastener 112 may also include a non-rotating fastener, and the minimum width of the fastener 112 is greater than the aperture of the connecting hole 111a. In this way, it can be ensured that the fastener 112 will not be separated from the connecting column 111 along the connecting hole 111a, and the fastener 112 can be reliably placed in the annular groove. In addition, after the non-rotating fastener is adapted to be configured in the annular groove, even if it is not integrally formed with the connecting column 111, the fastener 112 can be prevented from rotating relative to the connecting column 111, ensuring that the fastening connection structure 10 formed by the connecting member 12 after being connected to the fastener 112 is stable and reliable. For example, the fastener 112 is a hexagonal nut, and the style of this fastener 112 is more common and convenient for production. Exemplarily, the fastener 112 and the connecting column 111 are integrally formed to further ensure that the fastener 112 is stably and reliably arranged on the connecting column 111.

[0079] In the above embodiment, the fastener 112 is provided with a fastening hole 112a, and the inner diameter of the fastening hole 112a is not greater than the aperture of the connecting hole 111a. It should be noted that the fastening hole 112a is used for fastening and connecting the connecting member 12. The inner diameter mentioned here refers to the smallest diameter of the fastening hole 112a. When the fastener 112 is a fastening nut, it refers to the nominal diameter of the fastening nut. In this embodiment, the fastening hole 112a is partially protruded from the side wall of the connecting hole 111a, which can ensure that the connecting member 12 can be fastened and connected to the fastening hole 112a after being inserted into the connecting hole 111a. For example, an internal thread is provided in the fastening hole 112a to be threadedly connected with the external thread of the connecting member 12 to achieve fastening. Exemplarily, the fastener 112 includes a fastening nut, the nominal diameter of the fastening nut is larger than the aperture of the connecting hole 111a, and the root diameter of the fastening nut is consistent with the aperture of the connecting hole 111a. In this way, it can be ensured that the fastener 112 is firmly fitted and placed in the annular groove, and for the connected connector 12, the gap between it and the connecting hole 111a can also be reduced, ensuring that after the fastener 112 is fastened, the part of the connector 12 extending into the connecting hole 111a can be firmly and reliably placed in the connecting hole 111a and is not easy to shake.

[0080] like Figure 3 and Figure 4 As shown, in other embodiments, the annular groove is provided on the side of the connecting column 111. In this embodiment, the fastener 112 is placed outside the connecting column 111. When the connecting member 12 is tightly connected to the connecting component 11, the connecting member 12 is sleeved on the side of the connecting column 111 from one side of the free end 1111 of the connecting column 111, and is tightly connected to the fastener 112. By placing the connecting column 111 inside the connecting member 12, the connecting component 11 can be positioned, so as to facilitate and quickly realize the tight connection between the connecting member 12 and the connecting component 11.

[0081] Exemplarily, the connecting column 111 is a solid column, which, on the one hand, facilitates the molding of the connecting column 111 , and on the other hand, ensures that the connecting column 111 has sufficient structural strength.

[0082] Exemplarily, the outer side of the fastener 112 and the inner side of the connecting column 111 are threadedly connected to facilitate quick connection and disassembly of the connecting member 12 and the connecting component 11. It can be understood that at this time, the connecting component 11 can be a screw, and the connecting member 12 can be regarded as a nut.

[0083] In the above embodiment, the fastener 112 is provided with a fastening hole 112a, and the fastening hole 112a includes a circular fastening hole, and the diameter of the fastening hole 112a is smaller than the outer diameter of the connecting column 111. In this way, it can be ensured that the fastener 112 will not be separated from the connecting column 111 along the circumferential side of the connecting column 111, and the fastener 112 can be reliably placed in the annular groove. In addition, the circular fastening hole can also facilitate the fastener 112 to be adapted and assembled in the annular groove. Exemplarily, the fastener 112 and the connecting column 111 are integrally formed to prevent the fastener 112 from rotating relative to the connecting column 111, and ensure that the fastening connection structure 10 formed by the connecting member 12 after being connected to the fastener 112 is stable and reliable.

[0084] Of course, the fastening hole 112a may also include a non-rotating fastening hole, and the minimum width of the fastening hole 112a is smaller than the outer diameter of the connecting column 111. In this way, it can be ensured that the fastener 112 will not be separated from the connecting column 111 along the circumferential side of the connecting column 111, and the fastener 112 can be reliably placed in the annular groove. In addition, after the non-rotating fastener is appropriately configured in the annular groove, even if it is not integrally formed with the connecting column 111, the fastener 112 can be prevented from rotating relative to the connecting column 111, ensuring that the fastening connection structure 10 formed by the connecting member 12 is stable and reliable after being connected to the fastener 112. Exemplarily, the fastener 112 and the connecting column 111 are integrally formed to further ensure that the fastener 112 is stably and reliably arranged on the connecting column 111.

[0085] In the above embodiment, the outer diameter of the fastener 112 is not less than the outer diameter of the connecting column 111. It should be noted that the outer diameter mentioned here refers to the maximum diameter of the fastener 112. When the fastener 112 is a fastening nut, it refers to the nominal diameter of the fastening nut. In this embodiment, the fastener 112 is partially protruded from the peripheral side of the connecting column 111, which can ensure that the fastening connection between the fastener 112 and the fastener 112 can be achieved after the connecting member 12 is sleeved on the connecting column 111. Exemplarily, the fastener 112 includes a fastening nut, the nominal diameter of the fastening nut is greater than the outer diameter of the connecting column 111, and the root diameter of the fastening nut is consistent with the outer diameter of the connecting column 111. In this way, it can be ensured that the fastener 112 is firmly adapted and placed in the annular groove, and the gap between the inside of the connected connecting member 12 and the connecting column 111 can also be reduced, ensuring that after the fastener 112 is fastened and connected to the fastener 112, the part of the connecting component 11 extending into the connecting member 12 can be firmly and reliably placed in the connecting member 12, and is not easy to shake.

[0086] like Figures 1 to 4As shown, in some embodiments, the axial length of the annular groove along the connecting column 111 is not greater than the distance from the annular groove to the free end 1111. For example, the axial length of the annular groove along the connecting column 111 is consistent with the distance from the annular groove to the free end 1111. In this way, it can be ensured that there is sufficient strength between the groove wall of the annular groove and the free end 1111 to prevent the fastener 112 from axially separating from the connecting column 111, thereby ensuring the strength of the connection between the connecting component 11 and the connecting member 12.

[0087] like Figure 2 and Figure 4 As shown, an embodiment of the present application further provides a fastening connection structure 10 , which is applied to an energy storage device and includes a first component 13 , a second component 14 and a connecting member 12 .

[0088] The first component 13 is provided with a through hole 13a. The second component 14 is provided with a connecting component 11. The connecting member 12 passes through the through hole 13a and is firmly connected to the connecting component 11; or the connecting component 11 passes through the through hole 13a and is firmly connected to the connecting component 11.

[0089] It should be noted that in this embodiment, whether the connecting member 12 passes through the through hole 13a or the connecting member 11 passes through the through hole 13a, the connecting member 12 can be buckled on the first member 13, so that after the connecting member 12 and the connecting member 11 are fastened, the first member 13 is pressed against the second member 14 to achieve a fastened connection between the two.
