[0036] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0037] Below, reference is made to Figures 1-6 Describe the locking structure according to an embodiment of the present utility model. The locking structure mainly plays a role in locking and connecting.

[0038] As Figures 4-6 shown, the locking structure includes: an interlocking assembly, a locking member, and a driving assembly. Among them, the interlocking assembly 12 mainly plays an interlocking role. The locking member 22 mainly plays a limiting role. The driving assembly mainly plays a driving role.

[0039] As Figure 6 shown, the interlocking assembly 12 is adapted to be disposed on the surface of the first side plate 212 of the box body 1. The interlocking assembly 12 includes: a plug member 13. That is to say, the interlocking assembly 12 can be disposed on the surface of the first side plate 212 of the box body 1, so that some components on the interlocking assembly 12 can be fixed, making the setting of the interlocking assembly 12 more reliable and stable, so that the interlocking assembly 12 can work better. The plug member 13 mainly plays a role in plugging and fitting. The interlocking assembly 12 can be plugged and fitted with corresponding components through the plug member 13, so as to realize the locking of the box body 1. It should be noted that the box body 1 can play a role in storing and releasing electric energy.

[0040] As Figure 5 and Figure 6 shown, the locking member 22 is adapted to be disposed on the surface of the second side plate 112 of the box body 1, and the first side plate 212 is disposed opposite to the second side plate 112. That is to say, the locking member 22 can be disposed on the surface of the second side plate 112 of the box body 1, so that the locking member 22 can be fixed, and the setting of the locking member 22 is more reliable and stable, so that the locking member 22 can work better. The first side plate 212 and the second side plate 112 are disposed opposite to each other, which facilitates the locking cooperation between the interlocking components 12 on different box bodies 1 and the locking member 22.

[0041] As Figures 2-6 shown, the driving assembly is adapted to be disposed on the surface of the first side plate 212 of the box body 1, and the driving assembly is used to drive the bolt member 13 on one box body 1 to be in locking cooperation with the locking member 22 on another box body 1. That is to say, the driving assembly can be disposed on the surface of the first side plate 212 of the box body 1, so that some components in the driving assembly can be fixed, and the setting of the driving assembly is more reliable and stable, so that the driving assembly can work better. Specifically, the driving assembly can drive the bolt member 13 on one box body 1 to be in locking cooperation with the locking member 22 on another box body 1. That is to say, there are multiple box bodies 1, and the driving assembly on one box body 1 can drive the bolt member 13 on this box body 1 to be in locking cooperation with the locking member 22 on another box body 1, so that the locking cooperation between two box bodies 1 or multiple box bodies 1 can be realized.

[0042] Therefore, by disposing the interlocking component 12 on the surface of the first side plate 212 of the box body 1, disposing the locking member 22 on the surface of the second side plate 112 of the box body 1, and using the driving assembly to drive the bolt member 13 to cooperate with the locking member 22, the locking between different box bodies 1 can be realized. The cooperation mode of the bolt member 13 and the locking member 22 is simple, which can improve the accuracy of the box body 1 during installation, and further improve the stability of the box body 1, and is convenient for loading, unloading and maintenance.

[0043] In addition, as Figures 4-6 shown, the interlocking component 12 further includes: a fixing member 14, the fixing member 14 is provided with a fitting hole 141, the locking member 22 is provided with a plugging hole 221, one end of the bolt member 13 passes through the fitting hole 141, and the other end of the bolt member 13 selectively passes through the plugging hole 221. Among them, the fixing member 14 mainly plays a supporting role. The fitting hole 141 mainly plays a role of fitting and limiting. One end of the bolt member 13 passes through the fitting hole 141. Since the fitting hole 141 is provided on the fixing member 14, the fitting hole 141 can support and limit one end of the bolt member 13, so that the bolt member 13 can move better, and further the bolt member 13 can play a better locking role.

[0044] The locking member 22 mainly plays a role in supporting and locking cooperation, and the insertion hole 221 mainly plays a role in insertion cooperation. The other end of the bolt member 13 selectively passes through the insertion hole 221. Since the insertion hole 221 is provided on the locking member 22, that is to say, the other end of the bolt member 13 selectively engages with the locking member 22 in a locking manner. Specifically, when it is necessary to lock two boxes 1, the driving assembly can be used to drive the bolt member 13 to move and select to engage with the insertion hole 221, so that the locking between the two boxes 1 can be achieved, and thus the connection between the two boxes 1 can be made more stable. When it is necessary to unlock the two boxes 1, the driving assembly drives the bolt member 13 to move in the reverse direction. At this time, the bolt member 13 will disengage from the insertion hole 221, so that the two boxes 1 can be unlocked. During the movement of the bolt member 13, the inner wall of the mating hole 141 and the inner wall of the insertion hole 221 can both support the bolt member 13, so that the movement of the bolt member 13 can be more stable. It should be noted that the number of boxes 1 is not limited to two, and the two boxes 1 described above are any two adjacent boxes 1.

[0045] In addition, as Figure 5 and Figure 6 shown, a guiding portion 131 is provided at the other end of the bolt member 13. In the direction from the fixing member 14 to the locking member 22, the cross-sectional area of the guiding portion 131 gradually decreases. The guiding portion 131 mainly plays a guiding role. Since when the two boxes 1 are locked, the moving direction of the bolt member 13 is from the fixing member 14 to the locking member 22, therefore, in the direction from the fixing member 14 to the locking member 22, the cross-sectional area of the guiding portion 131 gradually decreases. Such a setting is more reasonable, which can reduce the cross-sectional area of the guiding portion 131 near the end of the insertion hole 221, so that when the bolt member 13 moves, it is convenient for the bolt member 13 to cooperate with the insertion hole 221, and thus the speed of the locking cooperation can be improved.

[0046] Furthermore, as Figure 6 shown, the driving assembly includes an operating member 121. One end of the operating member 121 is connected to the bolt member 13, and the other end of the operating member 121 is adapted to pass through the surface of the third side plate 111 of the box 1. The third side plate 111 is connected between the first side plate 212 and the second side plate 112. Among them, the operating member 121 mainly plays a role in transmission. Connecting one end of the operating member 121 to the bolt member 13 can make the connection between the operating member 121 and the bolt member 13 more stable, so that when corresponding operations are performed on the operating member 121, the operating member 121 can better drive the bolt member 13 to move, and thus the cooperation between the bolt member 13 and the locking member 22 can be better completed.

[0047] The third side plate 111 is connected between the first side plate 212 and the second side plate 112, so that the third side plate 111 can be fixed, making the setting of the third side plate 111 more secure and stable. It should be noted that the first side plate 212, the second side plate 112 and the third side plate 111 can form the external structure of the box body 1. The other end of the operating member 121 is adapted to pass through the surface of the third side plate 111 of the box body 1. That is to say, one end of the operating member 121 is connected to the latch member 13, and the other end of the operating member 121 extends to the outside of the box body 1. Such a setting is more reasonable, facilitating the operator to operate the operating member 121, so that the latch member 13 can be driven to move by the operating member 121.

[0048] In addition, as Figure 2 and Figure 3 shown, the drive assembly further includes a gripping portion 1211, and the gripping portion 1211 is connected to one end of the operating member 121 passing through the surface of the third side plate 111 of the box body 1. Among them, the gripping portion 1211 mainly plays a driving role. Connecting the gripping portion 1211 to one end of the operating member 121 passing through the surface of the third side plate 111 of the box body 1 can make the connection between the gripping portion 1211 and the operating member 121 more stable, so that the operator can drive the operating member 121 to move by moving the gripping portion 1211, and then drive the latch member 13 to move through the operating member 121.

[0049] Furthermore, the gripping portion 1211 is integrally formed on the operating member 121; or the gripping portion 1211 is bent and connected to the operating member 121; or the gripping portion 1211 is welded to the operating member 121; or the gripping portion 1211 is plugged into the operating member 121; or the gripping portion 1211 is adhesively connected to the operating member 121.

[0050] That is to say, there can be various connection relationships between the gripping portion 1211 and the operating member 121. For example: the gripping portion 1211 can be integrally formed on the operating member 121. In this way, when processing the gripping portion 1211 and the operating member 121, only one mold needs to be set, which is convenient for processing and setting. Or the gripping portion 1211 is welded to the operating member 121, which can make the connection between the gripping portion 1211 and the operating member 121 more stable and not easily damaged. Of course, the gripping portion 1211 and the operating member 121 can also be bent and connected, or plugged and connected, or adhesively connected. Other suitable connection methods are also possible.

[0051] Specifically, the gripping portion 1211 is a plastic part with a textured surface. The rubber part with texture can increase the friction force on the surface of the gripping portion 1211. Thus, when the operator moves the gripping portion 1211, the hand part is not likely to slip relative to the gripping portion 1211, so that the operator can control the gripping portion 1211 more stably.

[0052] In addition, if Figure 6 As shown, the driving assembly also includes a fastener 122, and the operating member 121 is fixed to the latch member 13 through the fastener 122. Among them, the fastener 122 mainly plays a fixing role. The operating member 121 is fixed to the latch member 13 through the fastener 122, so that the connection between the operating member 121 and the latch member 13 can be more stable, so that when the operating member 121 is operated, the operating member 121 can drive the latch member 13 to move more stably, and then the latch member 13 and the locking member 22 can be better matched.

[0053] As an optional embodiment, the driving assembly includes: a buckle part 1211, the buckle part 1211 is a magnetic part, and the buckle part 1211 is magnetically attracted to the latch part 13, so as to drive the latch part 13 remotely through the buckle part 1211. In other words, the buckle part 1211 can also be set as a magnetic part, so that there is no need to set the fastener 122 and the operating part 121, and the buckle part 1211 is directly magnetically attracted to the latch part 13, so that the stable connection between the buckle part 1211 and the latch part 13 can be ensured, and the buckle part 1211 does not need to be penetrated by the third side plate 111 or the third side plate 211, so that it will be simpler and more convenient during production and installation.

[0054] In addition, the handle 1211 is magnetically attracted to the surface of the third side plate 111 of the box body 1. In other words, the handle 1211 can be arranged outside the box body 1, because the operator is located outside the box body 1, so this arrangement is more reasonable and convenient for the operator to operate the handle 1211.

[0055] Furthermore, if Figure 6 As shown, the interlocking assembly 12 further includes: an avoidance groove 113, the locking member 22 is matched with the avoidance groove 113, the latch member 13 extends into the avoidance groove 113, and the latch member 13 is locked and matched with the locking member 22. Among them, the avoidance groove 113 mainly plays the role of avoidance, and the locking member 22 is matched inside the avoidance groove 113, so that the latch member 13 can avoid interference with other components when matching with the locking member 22. Therefore, such a setting is more reasonable and facilitates the adaptation of the avoidance groove 113 and the locking member 22.

[0056] Specifically, when the latch 13 is plugged into the locking member 22, the latch 13 is plugged into the locking member 22 inside the avoidance groove 113. Since the plugging process is performed inside the avoidance groove 113, the plug 13 and the locking member 22 can be more stably matched. In addition, when the latch 13 passes through the avoidance groove 113, the avoidance groove 113 can also support the latch 13, so that the movement of the latch 13 can be more stable.

[0057] As Figure 2 and Figure 4 shown, the box body 1 according to the embodiment of the present utility model includes the locking structure described in the above embodiment. A latch member 13 is provided on the surface of the first side plate 212 of the box body 1; and / or a locking member 22 is provided on the surface of the second side plate 112 of the box body 1. That is to say, the latch member 13 can be provided on the surface of the first side plate 212 of the box body 1, or the locking member 22 is provided on the surface of the second side plate 112 of the box body 1. Or, the latch member 13 is provided on the surface of the first side plate 212 of the box body 1, and the locking member 2 is provided on the surface of the second side plate 112 of the box body 1.

[0058] For example, when there are three box bodies 1, namely the upper box body 1, the middle box body 1, and the lower box body 1, at this time, the latch member 13 is provided on the surface of the first side plate 212 of the middle box body 1, and the locking member 22 is provided on the surface of the second side plate 112 of the box body 1. The latch member 13 is provided on the surface of the first side plate 212 of the upper box body 1, and the locking member 22 is provided on the surface of the second side plate 112 of the lower box body 1. In this way, the locking member 22 on the middle box body 1 can be locked and cooperated with the latch member 13 on the upper box body 1, and the latch member 13 of the middle box body 1 can be locked and cooperated with the locking member 22 on the lower box body 1, so as to realize the locking cooperation between the three box bodies 1. The locking cooperation of multiple box bodies 1 can be analogized in this way.

[0059] As Figure 1 and Figure 2 shown, the energy storage system 2 according to the embodiment of the present utility model includes: a first box body 10, and the first box body 10 is the box body 1 described in the above embodiment; a second box body 20, and the second box body 20 is the box body 1 described in the above embodiment. The first box body 10 and the second box body 20 are stacked. That is to say, the number of box bodies 1 can be multiple, and the energy storage system 2 is formed by stacking multiple box bodies 1. Moreover, the first box body 10 and the second box body 20 are connected in an interlocking manner, which is convenient for loading, unloading and maintenance. Since screws are not used during the installation process, the situation of missing installation will not occur.

[0060] In addition, as Figure 1 and Figure 2 shown, the energy storage system 2 further includes: a base 201, and the first box body 10 and the second box body 20 are stacked on the base 201. Among them, the base 201 mainly plays the role of installation and support. Stacking the first box body 10 and the second box body 20 on the base 201 can fix the first box body 10 and the second box body 20, making the first box body 10 and the second box body 20 more reliable and stable. Stacking the first box body 10 and the second box body 20 on the base 201 is convenient for loading, unloading and maintenance, and can reduce the space occupied on the ground.

[0061] In addition, as Figure 1 and Figure 2 shown, the first box body 10 is a battery box, and there is at least one first box body 10. The second box body 20 is at least one of a base 201, a battery box, and a battery management module. An interlock assembly 12 is provided on one of the first box body 10 and the second box body 20, and a locking member 22 is provided on the other of the first box body 10 and the second box body 20. That is to say, both the first box body 10 and the second box body 10 can be battery boxes, mainly playing the role of storing and releasing electric energy. Moreover, the number of the first box bodies 10 can be one or multiple, so that multiple battery boxes can be stored, and thus a larger amount of electric energy can be stored.

[0062] In addition to being a battery box, the second box body 20 can also be a base 201 or a battery management module. Of course, the second box body 20 can also be multiple of a battery box, a base 201, or a battery management module. When the second box body 20 is a battery box, the power storage capacity of the energy storage system 2 can be increased. When the second box body 20 is a base 201, it can be used for installing and fixing the corresponding battery box. When the second box body 20 is a battery management module, the second box body 20 can monitor the state of the corresponding battery box, so as to ensure the normal operation of the energy storage system 2.

[0063] An interlock assembly 12 is provided on one of the first box body 10 and the second box body 20, and a locking member 22 is provided on the other of the first box body 10 and the second box body 20. That is to say, if the interlock assembly 12 is provided on the first box body 10, then the locking member 22 is provided on the second box body 20. Through the locking cooperation between the interlock assembly 12 and the locking member 22, the connection between the first box body 10 and the second box body 20 can be made more stable, so that the energy storage system 2 can work better.

[0064] Furthermore, as Figure 2 shown, a fourth side plate 202 is provided on the base 201, and one of the first box body 10 and the second box body 20 is in locking cooperation with the fourth side plate 202. Among them, the fourth side plate 202 mainly plays the role of support and installation. By providing the fourth side plate 202 on the base 201, the fourth side plate 202 can be fixed, making the setting of the fourth side plate 202 more reliable and stable, and the fourth side plate 202 can play a better supporting role.

[0065] One of the first box body 10 and the second box body 20 is in locking cooperation with the fourth side plate 202. That is to say, when the first box body 10 is arranged adjacent to the base 201, the first box body 10 can be in locking cooperation with the fourth side plate 202, so that the first box body 10 can be fixed, making the connection between the first box body 10 and the base 201 more stable, and thus the first box body 10 can work better. Similarly, when the second box body 20 is arranged adjacent to the base 201, the second box body 20 can be in locking cooperation with the fourth side plate 202, so that the second box body 20 can be fixed, making the connection between the second box body 20 and the base 201 more stable, and thus the second box body 20 can work better.
