[0050] An embodiment of the present application provides an interlocking structure, and the interlocking structure of the present application is described in detail below with reference to the accompanying drawings.

[0051] Reference Figure 1 to Figure 2 , which shows a schematic diagram of the interlocking state of an interlocking structure provided in an embodiment of the present application, with reference to Figure 3 to Figure 4 , showing a schematic diagram of the unlocked state of an interlocking structure provided in an embodiment of the present application, with reference to Figures 5 to 7 , showing a schematic diagram of the assembly process of two adjacent battery boxes of an energy storage power supply provided in an embodiment of the present application.

[0052] like Figures 1 to 4 As shown, the present application provides an interlocking structure, which includes a first locking member 1, a second locking member 2 and a driving member 3; the first locking member 1 is suitable for being arranged in one module; the second locking member 2 is suitable for being arranged in another module and can overlap with the first locking member 1 to achieve the interlocking of the two modules; the driving member 3 is connected to the first locking member 1, and the driving member 3 is used to drive the first locking member 1 to move in a direction away from the second locking member 2 so that the second locking member 2 is released from overlapping with the first locking member 1.

[0053] In practical applications, when the module is a battery box 8 and at least two battery boxes 8 are stacked to form an energy storage battery, for two adjacent battery boxes 8, since one of the battery boxes 8 is provided with a first locking member 1 and the other battery box 8 is provided with a second locking member 2, the first locking member 1 can overlap with the second locking member 2, thereby achieving interlocking of the two adjacent battery boxes 8. This connection method is simple and convenient, which is conducive to improving the overall structural strength and assembly efficiency of the energy storage battery. In addition, since a driving member 3 is provided, the driving member 3 can drive the first locking member 1 to move in a direction away from the second locking member 2 to release the overlap, thereby conveniently releasing the interlocking of the two adjacent battery boxes 8, which is conducive to improving the disassembly efficiency of the energy storage power supply.

[0054] In some optional embodiments of the present application, the first locking member 1 is suitable for being fixedly connected to the module, and the first locking member 1 can undergo elastic deformation; under the drive of the driving member 3, the first locking member 1 elastically deforms in a direction away from the second locking member 2 so that the second locking member 2 is released from overlapping with the first locking member 1.

[0055] In the embodiment of the present application, since the first locking member 1 can be elastically deformed, during the stacking of the battery boxes 8, under the action of external force or the deadweight of the battery boxes 8, the first locking member 1 can be elastically deformed to reliably overlap with the second locking member 2, thereby realizing reliable interlocking of two adjacent battery boxes 8. In addition, under the drive of the driving member 3, the second locking member 2 can be elastically deformed in a direction away from the second locking member 2, so that the second locking member 2 is released from the overlap with the first locking member 1, thereby realizing the rapid unlocking of the two battery boxes 8.

[0056] It should be noted that the interlocking structure of the embodiment of the present application has an interlocking state and an unlocking state, the interlocking state refers to the state where the first locking member 1 and the second locking member 2 are overlapped, and the unlocking state refers to the state where the first locking member 1 and the second locking member 2 are released from overlapping. In addition, the material of the first locking member 1 includes but is not limited to plastic, rubber or other elastically deformable materials, which are not limited here, and those skilled in the art can choose according to actual needs.

[0057] In practical applications, in the process of stacking the battery boxes 8, in order to enable the two adjacent battery boxes 8 to be interlocked, each battery box 8 is usually provided with a first locking member 1 and a second locking member 2 at the same time, so that the battery box 8 overlaps with the second locking member 2 and the first locking member 1 of the two adjacent battery boxes 8 respectively. Specifically, the battery box 8 includes a first mounting plate 83 and a second mounting plate 84 spaced apart along the first direction X, wherein the first locking member 1 is provided on the first mounting plate 83, and the second locking member 2 is provided on the second mounting plate 84 and is opposite to the position of the first locking member 1. In this way, in the process of stacking the battery boxes 8, the first locking member 1 of the first mounting plate 83 of one of the battery boxes 8 can always overlap with the second locking member 2 of the second mounting plate 84 of the adjacent battery box 8, thereby achieving the interlocking of the two adjacent battery boxes 8, which is beneficial to improving the overall structural strength of the energy storage power supply.

[0058] In practical applications, the driving member 3 includes but is not limited to a push-pull electromagnet, a cylinder, a motor, etc. In one embodiment, the driving member 3 is a push-pull electromagnet, and the push-pull electromagnet includes a push-pull rod. When the push-pull electromagnet is energized, the push-pull rod can move in a direction away from the first locking member 1, thereby driving the second locking member 2 to elastically deform in a direction away from the second locking member 2, so that the first locking member 1 and the second locking member 2 are released from overlapping, and at this time, the interlocking structure is in an unlocked state. Compared with cylinders and motors, push-pull electromagnets usually have a smaller volume, which can save installation space and help reduce the occupation of the internal space of the battery box 8. In addition, those skilled in the art can select a suitable push-pull electromagnet according to the elastic deformation performance of the first locking member 1, which is not limited here.

[0059] In some optional embodiments of the present application, the first locking member 1 is a first buckle, and the second locking member 2 is a second buckle; the first buckle is buckled with the second buckle; under the drive of the driving member 3, the first buckle elastically deforms in a direction away from the second buckle to release the first buckle from the second buckle.

[0060] In the embodiment of the present application, since the first locking member 1 and the second locking member 2 are respectively the first buckle and the second buckle, that is, the first locking member 1 and the second locking member 2 are both buckles with simple structures, the interlocking and releasing of the two adjacent battery boxes 8 can be achieved by engaging and releasing the two buckles. This interlocking structure is simple and easy to process, which is conducive to reducing the manufacturing cost of the interlocking structure.

[0061] It should be noted that, in the process of stacking the battery boxes 8, in order to enable two adjacent battery boxes 8 to be interlocked, each battery box 8 is usually provided with a first buckle and a second buckle at the same time. Specifically, the battery box 8 includes a first mounting plate 83 and a second mounting plate 84 spaced apart along the first direction X, wherein the first buckle is provided on the first mounting plate 83, and the second buckle is provided on the second mounting plate 84. In one embodiment, the first buckle includes a first fixing portion 12 and a first clamping portion 13, the first fixing portion 12 has a first end and a second end disposed away from each other along the first direction X, the second end is disposed near the center of the battery box 8 and connected to the first mounting plate 83, the first clamping portion 13 is connected to the first end, and the first clamping portion 13 extends in the direction of the second buckle. The second buckle includes a second fixing portion 21 and a second clamping portion 22, the second fixing portion 21 has a third end and a fourth end disposed away from each other along the first direction X, the fourth end is disposed near the center of the battery box 8 and connected to the second mounting plate 84, the second clamping portion 22 is connected to the third end, and the second clamping portion 22 extends in the direction of the first buckle. That is, the first buckle and the second buckle are both roughly "L"-shaped, and the interlocking of two adjacent battery boxes 8 can be achieved by fastening the first buckle and the second buckle of two adjacent battery boxes 8 along the vertical direction. This connection method is simple and convenient, which is conducive to improving the assembly efficiency of the energy storage battery.

[0062] In actual application, in the process of stacking the battery boxes 8, in order to facilitate the smooth buckling of the first buckle and the second buckle, in the embodiment of the present application, the first clamping portion 13 has a first inclined surface on the side away from the first fixing portion 12; the second clamping portion 22 has a second inclined surface adapted to the first inclined surface on the side away from the second fixing portion 21. In this way, when the first battery box 81 is stacked on the second battery box 82, the first inclined surface of the first buckle and the second inclined surface of the second buckle first abut against each other, and then under the action of external force or the gravity of the first battery box 81, the first buckle undergoes elastic deformation and buckles with the second buckle, at which time the first clamping portion 13 and the second clamping portion 22 limit each other, so that the interlocking of the first battery box 81 and the second battery box 82 can be smoothly achieved.

[0063] In some optional embodiments of the present application, the interlocking structure further includes a connecting member 4, which is disposed between the first locking member 1 and the driving member 3, and the connecting member 4 is connected to the first locking member 1 and the driving member 3 respectively.

[0064] In the embodiment of the present application, since the connecting member 4 is provided between the first locking member 1 and the driving member 3, and the connecting member 4 is respectively connected to the first locking member 1 and the driving member 3. In this way, the connecting member 4 can transmit the driving force of the driving member 3 to the first locking member 1, so that the first locking member 1 is elastically deformed in a direction away from the second locking member 2, so that the interlocking structure is in an unlocked state, so as to facilitate the removal of the battery box 8.

[0065] In some optional embodiments of the present application, a connecting portion 11 is provided on a side of the first locking member 1 facing away from the second locking member 2; the driving member 3 includes a driving end 31, and the driving end 31 is provided close to the first locking member 1; and the connecting member 4 is respectively connected to the connecting portion 11 and the driving end 31. By connecting the connecting member 4 to the connecting portion 11 and the driving end 31, the transmission of the driving force can be achieved.

[0066] In a specific application, the first locking member 1 is a first buckle, and the connecting portion 11 is arranged at the end of the first clamping portion 13 away from the second buckle to facilitate the connection between the connecting portion 11 and the driving end 31, wherein, when the driving member 3 is a push-pull electromagnet, the driving end 31 refers to the end of the push-pull rod close to the first locking member 1.

[0067] In some optional embodiments of the present application, the connecting portion 11 is provided with a first connecting hole 111, and the driving end 31 is provided with a second connecting hole 311; the connecting member 4 is an annular connecting member, and the annular connecting member passes through the first connecting hole 111 and the second connecting hole 311 respectively.

[0068] In the embodiment of the present application, since the connecting portion 11 is provided with a first connecting hole 111, the driving end 31 is provided with a second connecting hole 311, and the annular connecting member is respectively provided through the first connecting hole 111 and the second connecting hole 311. In this way, the connecting portion 11 and the driving end 31 can be reliably connected together to facilitate the transmission of the driving force.

[0069] It should be noted that the first connecting hole 111 has a first axis, and the second connecting hole 311 has a second axis. In one embodiment, when the interlocking structure is in the interlocking state, the first axis is parallel to the second axis, so that the annular connecting member is connected to the first connecting hole 111 and the second connecting hole 311 at the same time.

[0070] In practical applications, the connector 4 can be a rigid connector or a flexible connector, which is not limited here, and those skilled in the art can make a choice according to actual needs. It can be understood that, since the running track of the connecting portion 11 is roughly arc-shaped during the elastic deformation of the first locking member 1, when the connector 4 is a flexible connector, the contact position between the connector 4 and the first connecting hole 111 and the second connecting hole 311 can be adaptively adjusted, thereby improving the transmission uniformity of the driving force and avoiding the problem of damage to the first locking member 1 due to excessive local tensile stress. In one embodiment, the flexible connector is a drawstring.

[0071] In summary, the interlocking structure provided by the embodiment of the present application includes at least the following advantages:

[0072] In the embodiment of the present application, since the interlocking structure includes a first locking member, a second locking member and a driving member; the first locking member is suitable for being set in one module; the second locking member is suitable for being set in another module and can overlap with the first locking member to achieve the interlocking of the two modules; the driving member is connected to the first locking member, and the driving member is used to drive the first locking member to move in a direction away from the second locking member, so that the second locking member and the first locking member are released from overlapping. In this way, when the module is a battery box and at least two battery boxes are stacked to form an energy storage battery, for two adjacent battery boxes, since one of the battery boxes is provided with a first locking member and the other battery box is provided with a second locking member, the first locking member can overlap with the second locking member, thereby achieving the interlocking of the two adjacent battery boxes. This connection method is simple and convenient, which is conducive to improving the overall structural strength and assembly efficiency of the energy storage battery. In addition, since a driving member is provided, the driving member can drive the first locking member to move in a direction away from the second locking member to release the overlap, thereby conveniently releasing the interlocking of the two adjacent battery boxes, which is conducive to improving the disassembly efficiency of the energy storage power supply.

In addition, in the embodiment of the present application, the structure of the interlocking structure is the same as the structure of the interlocking structure of any of the above embodiments, and its beneficial effects are similar, which will not be repeated here.

[0076] In a specific application, the interlocking structure further includes a base 5, which is connected to the mounting channel 831. The base 5 is used to fix the first locking member 1 and the driving member 3, so that the positions of the first locking member 1 and the driving member 3 are relatively fixed, and the first locking member 1 and the driving member 3 are installed in the mounting channel 831 as a whole, which is conducive to improving the installation convenience of the interlocking structure. In one embodiment, the base 5 includes a first connecting plate 51 and a second connecting plate 52 arranged perpendicular to each other, and the second connecting plate 52 is arranged parallel to the first mounting plate 83; the first connecting plate 51 is used to connect with the mounting channel 831, and the second connecting plate 52 is used to carry the driving member 3.

[0082] In the embodiment of the present application, since the first positioning member and the second positioning member are provided, the first positioning member is connected to the first battery box 81, and the second positioning member is connected to the second battery box 82 and is opposite to the first positioning member. In this way, the position of the battery box 8 can be restricted by the matching connection of the first positioning member and the second positioning member, so that the alignment installation of two adjacent battery boxes 8 can be achieved, so that the first locking member 1 and the second locking member 2 of the two adjacent battery boxes 8 can be further reliably connected.

[0083] In some optional embodiments of the present application, the first positioning member is one of the positioning groove 6 or the positioning protrusion 7, and the second positioning member is the other of the positioning groove 6 or the positioning protrusion 7, and the positioning groove 6 is engaged with the positioning protrusion 7. The alignment installation of two adjacent battery boxes 8 can be achieved by the engagement of the positioning groove 6 with the positioning protrusion 7. This concave-convex matching structure is simple, easy to process, and is conducive to reducing the manufacturing cost of the interlocking structure.

[0084] In practical applications, in the process of stacking the battery boxes 8, in order to enable the two adjacent battery boxes 8 to be installed in alignment, each battery box 8 is usually provided with a positioning groove 6 and a positioning protrusion 7 at the same time. Specifically, in one embodiment, the battery box 8 includes a first mounting plate 83 and a second mounting plate 84 spaced apart along the first direction X, the positioning groove 6 is provided on the first mounting plate 83, and the positioning protrusion 7 is provided on the second mounting plate 84. In this way, in the process of stacking the battery boxes 8, the positioning groove 6 of the first mounting plate 83 of one of the first battery box 81 or the second battery box 82 can be engaged with the positioning protrusion 7 of the second mounting plate 84 of the other of the first battery box 81 or the second battery box 82, thereby achieving the alignment of the two adjacent battery boxes 8, so that the first locking member 1 and the second locking member 2 of the two adjacent battery boxes 8 are further reliably connected.

[0085] It should be noted that, in the drawings shown in the embodiment of the present application, only the structure in which the positioning groove 6 is arranged on the first mounting plate 83 and the positioning protrusion 7 is correspondingly arranged on the second mounting plate 84 is shown, while in actual applications, those skilled in the art may also arrange the positioning protrusion 7 on the first mounting plate 83 and the positioning groove 6 on the second mounting plate 84, and the embodiment of the present application does not limit this.

[0086] In some optional embodiments of the present application, the positioning groove 6 is extended along the circumference of the mounting channel 831; the positioning protrusion 7 is arranged on the side of the second mounting plate 84 away from the first mounting plate 83 and extends along the circumference of the second locking member 2, and the positioning protrusion 7 is embedded in the positioning groove 6.

[0087] In the embodiment of the present application, since the positioning groove 6 is extended along the circumference of the installation channel 831, and the positioning protrusion 7 is extended along the circumference of the second locking member 2, during the process of stacking the first battery box 81 on the second battery box 82, the positioning groove 6 and the positioning protrusion 7 can first cooperate and guide the first battery box 81 to move toward the direction close to the second battery box 82 so as to be installed in alignment with the second battery box 82.

[0088] It should be noted that in order for the interlocking structure to achieve the effect of first positioning and then locking, under normal circumstances, the height of the second locking member 2 along the vertical direction is less than or equal to the height of the positioning protrusion 7 along the vertical direction, so that the positioning protrusion 7 and the positioning groove 6 can cooperate first, and under the guiding action of the positioning protrusion 7 and the positioning groove 6, the first locking member 1 and the second locking member 2 are overlapped again, which is beneficial to improve the connection reliability of the interlocking structure.

[0089] In some optional embodiments of the present application, the energy storage power supply also includes a sealing gasket (not shown in the drawings), which is arranged between the positioning groove 6 and the positioning protrusion 7, and is used for buffering and / or sealing the connection between the first battery box 81 and the second battery box 82.

[0090] In the embodiment of the present application, since a sealing gasket is provided between the positioning groove 6 and the positioning protrusion 7, on the one hand, it can play a buffering role in the stacking process of the first battery box 81 and the second battery box 82. On the other hand, the first battery box 81 and the second battery box 82 can be sealed and connected, effectively preventing water vapor from entering the energy storage power supply from the interlocking structure, improving the waterproof performance of the energy storage battery, and helping to improve the safety of the energy storage battery.

[0091] It should be noted that in order to improve the sealing performance of the battery box 8, the shape of the sealing gasket should be compatible with the cross-sectional shape of the positioning groove 6 or the positioning protrusion 7 along the vertical direction. The embodiment of the present application does not limit the shape of the sealing gasket, and those skilled in the art can adjust it according to actual needs. In one embodiment, the cross-sectional shape of the positioning groove 6 and the positioning protrusion 7 along the vertical direction is annular, and correspondingly, the shape of the sealing gasket is also annular. In another embodiment, the cross-sectional shape of the positioning groove 6 and the positioning protrusion 7 along the numerical direction is square, and correspondingly, the shape of the sealing gasket is also square.

[0092] Combination Figures 5 to 7 The following provides an example of an assembly process for interlocking and releasing two stacked battery boxes 8, namely, a first battery box 81 and a second battery box 82, using the interlocking structure of an embodiment of the present application. It should be noted that the assembly process example is based on the following application scenario: the first battery box 81 and the second battery box 82 are stacked in sequence from bottom to top along the vertical direction, and the first battery box 81 is the battery box 8 located at the top, and the second battery box 82 is the battery box 8 located at the bottom:

[0093] 1. Interlocking process:

[0094] First, the first battery box 81 is placed above the second battery box 82. During the falling process of the first battery box 81, the positioning groove 6 provided on the first mounting plate 83 of the first battery box 81 first cooperates with the positioning protrusion 7 of the second mounting plate 84 of the second battery box 82. Secondly, the first locking member 1 provided on the first mounting plate 83 of the first battery box 81 abuts against the second locking member 2 provided on the second mounting plate 84 of the second battery box 82. Figure 5 As shown, under the gravity of the first battery box 81, the first locking member 1 is elastically deformed and overlaps with the second locking member 2, as shown in FIG. Figure 6 As shown, the interlocking of the first battery box 81 and the second battery box 82 is completed.

[0095] 2. Unlocking process:

[0096] The driving member 3 is started. Under the driving action of the driving member 3, the first locking member 1 is elastically deformed in a direction away from the second locking member 2, and the first locking member 1 is released from overlapping with the second locking member 2, so that the first battery box 81 and the second battery box 82 are released from interlocking. Figure 7 As shown; in this case, the staff can transfer the first battery box 81 from above the second battery box 82.
