[0027] See also Figure 1 The energy storage device 100 includes at least one first module 10 and at least one second module 20 . Figure 1 FIG. 1 is a schematic diagram of an assembled energy storage device 100 , wherein the first module 10 and the second module 20 are arranged along a first direction X. Figure 2 and Figure 4 The first module 10 includes a first housing 11, and the energy storage device 100 includes a first fixing component 12 and a second fixing component 22. The first fixing component 12 is rotatably disposed on the first housing 11. Figure 3 The second module 20 includes a second housing 21, and a second fixing component 22 is fixed to the second housing 21. The second fixing component 22 can rotate relative to the second housing 21. Figure 5 When the first shell 11 and the second shell 21 are stacked, the first fixing component 12 is rotated to engage with the second fixing component 22, thereby fixing the first shell 11 and the second shell 21.
[0028] In some embodiments, see Figure 2 The first fixing assembly 12 includes a rotating member 121 , which is configured to be rotatably disposed on the first outer wall 111 of the first shell 11 , the rotating axis of the rotating member 121 is perpendicular to the first outer wall 111 , and the rotating member 121 is provided with a notch 1211 .
[0029] See also Figure 3 The second fixing assembly 22 includes a clamping member 221 and a limiting member 222. The clamping member 221 is fixed to the second housing 21, and the limiting member 222 is rotatably disposed on the clamping member 221. Figure 5 When the first fixing assembly 12 is connected to the second fixing assembly 22, the clamping member 221 is disposed in the notch 1211, the limiting member 222 is disposed on the side of the rotating member 121 away from the first housing 11, and the rotating member 121 is located between the second housing 21 and the limiting member 222. After the limiting member 222 rotates, it abuts against the rotating member 121 to fix the first housing 11 and the second housing 21.
[0030] The rotating member 121 in the energy storage device 100 of the embodiment of the present application is rotatably arranged on the first shell 11, and the rotating member 121 is provided with a notch 1211; the clamping member 221 is arranged on the second shell 21, and the limiting member 222 is rotatably arranged on the clamping member 221. When the rotating member 121 is driven to rotate, the notch 1211 on the rotating member 121 is clamped with the clamping member 221, and the limiting member 222 is driven to rotate so that the limiting member 222 abuts against the rotating member 121, thereby fixing the first shell 11 and the second shell 21. The assembly efficiency of the first module 10 and the second module 20 can be effectively improved by the rotating member 121 rotating and directly clamping with the clamping member 221, and the limiting member 222 abutting and connecting with the rotating member 121.
[0031] In some embodiments, see Figure 2 The rotating member 121 has a first side 1213 and a second side 1214 relative to each other. A portion of the first side 1213 is recessed toward the second side 1214 to form a notch 1211, which facilitates the notch 1211 to be directly connected to the snap-in member 221 after the rotating member 121 rotates, thereby improving the connection convenience.
[0032] In some embodiments, see Figure 2 The first fixing assembly 12 includes a first fixing member 122. The rotating member 121 is provided with a first through hole 1212. The first fixing member 122 is passed through the first through hole 1212 and connected to the first housing 11 to fix the rotating member 121 on the first housing 11. The installed rotating member 121 can rotate relative to the first housing 11, so that the rotating member 121 can rotate and connect with the clamping member 221.
[0033] As an example, the first fixing member 122 is a screw having a blocking portion 1221, and a threaded hole 112 is provided on the first shell 11. The first fixing member 122 passes through the first through hole 1212 from the side of the rotating member 121 away from the first shell 11 and is connected to the threaded hole 112. The rotating member 121 is located between the blocking portion 1221 and the first shell 11.
[0034] In some embodiments, see Figure 4 , the rotating member 121 has an initial position 121a relative to the first housing 11. Figure 4 The figure shows that the rotating member 121 is located at an initial position 121a relative to the first housing 11. The first fixing assembly 12 includes a limiting column 123, which is disposed on the first outer wall 111. The limiting column 123 is configured to abut against the rotating member 121 located at the initial position 121a, thereby limiting the rotation angle of the rotating member 121.
[0035] As an example, see Figure 4 and Figure 5The rotating member 121 has a first rotation direction M1 and a second rotation direction M2 relative to the first housing 11. When the rotating member 121 is driven to rotate along the first rotation direction M1, the rotating member 121 is connected with the second fixing assembly 22 by snapping, thereby fixing the first housing 11 and the second housing 21. When the rotating member 121 is driven to rotate along the second rotation direction M2, the rotating member 121 is separated from the second fixing assembly 22, thereby unlocking the first housing 11 and the second housing 21, until the second side edge 1214 of the rotating member 121 abuts against the limiting column 123, so that the limiting column 123 limits the rotating member 121 from continuing to rotate in the second rotation direction M2, thereby keeping the rotating member 121 at the initial position 121a.
[0036] See also Figure 4 When the energy storage device 100 is to be installed and the second side 1214 of the rotating member 121 is in contact with the limiting column 123, the rotating member 121 remains in an inclined state, and the second side 1214 of the rotating member 121 is located below the first side 1213 of the rotating member 121, forming a structure with the first fixed member 122 as a rotation fulcrum and the limiting column 123 as a blocking fulcrum. Under the action of the self-gravity G of the rotating member 121, the rotating member 121 can be stably maintained at the initial position 121a, thereby reducing the rotation of the rotating member 121 relative to the first housing 11. In addition, when assembling the first module 10 and the second module 20, the rotating member 121 can be directly driven to rotate from the initial position 121a to the second fixed component 22 for clamping connection, thereby reducing the steps of adjusting the position of the rotating member 121 to complete the assembly because the rotating member 121 is not in the initial position 121a, thereby improving the assembly efficiency.
[0037] In some embodiments, see Figure 4 , when the rotating member 121 is located at the initial position 121a, the rotating member 121 and the first housing 11 overlap, the profile of the rotating member 121 is located within the profile range of the first housing 11, and the rotating member 121 does not protrude from the first housing 11. When the rotating member 121 overlaps with the first housing 11 at the initial position 121a, the rotating member 121 is reduced from being bumped during transportation or installation, thereby maintaining the normal shape of the rotating member 121.
[0038] In some embodiments, see Figure 4 and Figure 5The first fixing assembly 12 includes a handle 124, which is disposed on a side of the rotating member 121 away from the first housing 11, and the handle 124 and the first through hole 1212 are located on opposite sides of the notch 1211; the handle 124 is configured to receive a force to drive the rotating member 121 to rotate relative to the first housing 11. By arranging the handle 124 on the rotating member 121, it is convenient for a user to drive the rotating member 121 to rotate, and the handle 124 and the first through hole 1212 are arranged oppositely in the length direction of the rotating member 121, which can extend the force arm between the handle 124 and the rotation fulcrum, thereby reducing the force applied by the user to drive the rotating member 121.
[0039] In some embodiments, see Figure 3 The clamping member 221 is fixed to the second housing 21, and the limiting member 222 is rotatably disposed on the clamping member 221. The limiting member 222 has a first position 222a and a second position 222b relative to the second housing 21. Figure 5 When the limiting member 222 is located at the first position 222a, the limiting member 222 is separated from the rotating member 121; see Figure 6 When the limiting member 222 is located at the second position 222 b , the limiting member 222 abuts against the rotating member 121 .
[0040] The fixing process of the first module 10 and the second module 20 is as follows: Figure 4 , the rotating member 121 is driven to rotate along the first rotation direction M1 from the initial position 121a until the notch 1211 of the rotating member 121 is engaged with the engaging member 221, as shown in FIG. Figure 5 Then, the limiting member 222 is rotated so that the limiting member 222 abuts against the rotating member 121, as shown. Figure 6 shown.
[0041] The initial state of the limiting member 222 is at the first position 222a. Figure 5 As shown, by driving the limiting member 222 to rotate from the first position 222a to the second position 222b, as shown in Figure 6 As shown, the limiting member 222 abuts against the rotating member 121 , and the rotating member 121 is locked between the second housing 21 and the limiting member 222 , thereby fixing the rotating member 121 on the second housing 21 , thus completing the fixing operation of the first module 10 and the second module 20 .
[0042] The unlocking process of the first module 10 and the second module 20 is as follows: Figure 6 , by driving the limiting member 222 to rotate from the second position 222b to the first position 222a. Figure 5As shown, the stopper 222 is separated from the rotating member 121, and the rotating member 121 is in an unlocked state. The handle 124 is continued to drive the rotating member 121 to rotate along the second rotation direction M2, and the clamping member 221 is separated from the notch 1211, so as to unlock the first module 10 and the second module 20 in the stacking direction, and the rotating member 121 is continued to be driven to rotate. Figure 4 As shown, until the rotating member 121 abuts against the limiting column 123 to be in the initial position 121 a , the unlocking operation of the first module 10 and the second module 20 is completed.
[0043] In addition, if Figure 6 As shown, when the rotating member 121 is driven to engage with the notch 1211 and the engaging member 221, under the action of its own gravity G, the rotating member 121 can maintain its posture and the user can continue to drive the limiting member 222 to rotate from the first position 222a to the second position 222b, effectively improving the convenience of operation.
[0044] In some embodiments, see Figure 3 and Figure 6 The limiting member 222 includes a first limiting member 2221 and a second limiting member 2222, and the first limiting member 2221 and the second limiting member 2222 are located on two opposite sides of the clamping member 221. When the limiting member 222 is in the second position 222b, the first limiting member 2221 abuts against the rotating member 121, and the second limiting member 2222 also abuts against the rotating member 121. By respectively arranging the first limiting member 2221 and the second limiting member 2222 on two opposite sides of the clamping member 221, when the limiting member 222 is in the second position 222b, it is possible to abut against the rotating member 121 at two positions at the same time, so that the fixing effect of the limiting member 222 on the rotating member 121 can be enhanced, and the risk of the limiting member 222 loosening relative to the rotating member 121 during use is reduced.
[0045] It is understandable that the first module 10 can be a battery module or a control module; the second module 20 can be a battery module or a control module, wherein the control module can include control components such as circuit boards, the battery module can include energy storage modules such as battery cells, and the control module is used to control the battery module to safely store or release electrical energy. The energy storage device 100 can be a whole composed of a battery module and a control module stacked together, or a whole composed of two or more battery modules and a control module stacked together, or a whole composed of two or more battery modules and two or more control modules stacked together.
[0046] In some embodiments, see Figure 7The energy storage device 100 includes at least one first module 10, at least two second modules 20, a plurality of first fixing components 12 and a plurality of second fixing components 22, wherein the first module 10 is a control module and the second module 20 is a battery module. The at least one first module 10 and the at least two second modules 20 are arranged in a first direction X, the first module 10 is provided with a first fixing component 12 and a second fixing component 22, and the second module 20 is also provided with a first fixing component 12 and a second fixing component 22. Adjacent first modules 10 and / or second modules 20 are connected by the first fixing component 12 and the second fixing component 22 to fix the first module 10 and / or the second module 20.
[0047] A first fixing component 12 is provided at the bottom of the first module 10, a second fixing component 22 is provided at the top of the second module 20, and a first fixing component 12 is provided at the bottom of the second module 20. The first module 10 is located above the second module 20, and the first fixing component 12 of the first module 10 is snap-connected with the second fixing component 22 of the second module 20. In the two second modules 20, the first fixing component 12 of the second module 20 located above is snap-connected with the second fixing component 22 of the second module 20 located below. The present application provides an embodiment of an electrical device, and the electrical device includes an energy storage device 100 in any of the above embodiments, and the energy storage device 100 is configured to store electrical energy and provide electrical energy to the electrical device. The specific structure and function of the energy storage device 100 can be referred to the above embodiments, which will not be repeated here.
[0048] The rotating member 121 in the energy storage device 100 of the embodiment of the present application is rotatably arranged on the first shell 11, and the rotating member 121 is provided with a notch 1211; the clamping member 221 is arranged on the second shell 21, and the limiting member 222 is rotatably arranged on the clamping member 221. When the rotating member 121 is driven to rotate, the notch 1211 on the rotating member 121 is clamped with the clamping member 221, and the limiting member 222 is driven to rotate so that the limiting member 222 abuts against the rotating member 121, thereby locking the first shell 11 and the second shell 21. Compared with the fixing method of screw threading in the prior art, the method of rotating the rotating member 121 and directly clamping it with the clamping member 221, and the limiting member 222 abutting and connecting with the rotating member 121 can effectively improve the assembly efficiency of the first module 10 and the second module 20.
