The two ends of any reinforcing rib are respectively connected to the inner wall of the seat body and the outer wall of the receiving groove, and the plurality of reinforcing ribs are evenly distributed along the circumference of the receiving groove. In this way, the wall surface of the seat body can be supported by the reinforcing ribs to improve the overall strength of the main body.

[0023] In some technical solutions, optionally, the dimension of an end of the main body connected to the buffer pad is smaller than the dimension of an end of the main body away from the buffer pad.

Then the first guide member connected to one of the second energy storage units is inserted into the second guide member provided at the other second energy storage unit. The size of the first guide member is close to that of the second guide member. When the first guide member is inserted into the second guide member, there is a small gap between the first guide member and the second guide member.

The user can directly connect the first energy storage unit 220 and the second energy storage unit 230 without using tools, thereby improving user convenience.

[0069] like Figure 2 and Figure 5 As shown, in some embodiments, optionally, the first guide member 110 is used to be connected to the bottom of the first energy storage unit 220 , and the second guide member 120 is used to be arranged on the top of the second energy storage unit 230 .

[0070] In this embodiment, the setting positions of the first guide member 110 and the second guide member 120 are limited. Specifically, the first guide member 110 is used to be connected to the bottom of the first energy storage unit 220, and the second guide member 120 is used to be arranged on the top of the second energy storage unit 230. In this way, the first guide member 110 can support the first energy storage unit 220. In addition, when the user needs to connect the first energy storage unit 220 with the second energy storage unit 230, the user can align the first guide member 110 with the second guide member 120, and then directly place the first energy storage unit 220 on the second energy storage unit 230. The first guide member 110 is directly inserted into the second guide member 120, and the user does not need to use professional tools for installation, which reduces the user's operating difficulty and improves the user's convenience.

[0072] In this embodiment, the first guide member 110 and the second guide member 120 are further defined. Specifically, the first guide member 110 is a convex structure, and the second guide member 120 is a groove structure. By setting the first guide member 110 as a convex structure, the first energy storage unit 220 is supported by the first guide member 110, so that the first guide member 110 plays a supporting role. In addition, by setting the first guide member 110 as a convex structure and the second guide member 120 as a groove structure, a concave-convex matching structure is formed between the first guide member 110 and the second guide member 120, so that the first guide member 110 is inserted into the second guide member 120, so that the guide device 100 can realize the guide limit function.

Specifically, when the main body 111 is connected to the first energy storage unit, the buffer pad 112 is located on the side of the main body 111 away from the first energy storage unit 220, and when the first energy storage unit 220 is placed on the ground, the buffer pad 112 contacts the ground. The buffer pad 112 is made of an elastic material, and specifically, the buffer pad 112 can be made of a rubber material. In this way, the buffer pad 112 can play a buffering role. When the first energy storage unit 220 is placed on the ground, the rigid contact between the first guide member 110 and the ground is avoided, and the buffer plays a shock absorbing role. When the first energy storage unit 220 is connected to the second energy storage unit 230, the first guide member 110 is inserted into the second guide member 120, and the buffer pad 112 contacts the wall surface of the second guide member 120. Since the buffer pad 112 is elastic, the first guide member 110 and the second guide member 120 are prevented from being damaged due to rigid contact.

[0075] like Figure 7 and Fig.10 As shown, in some embodiments, optionally, the main body 111 includes: a seat body 113, the seat body 113 has a receiving groove 116; a connecting member 114, located in the receiving groove 116, the connecting member 114 is fixedly connected to the seat body 113, and the connecting member 114 is used to connect to the first energy storage unit 220.

[0077] By disposing the connecting member 114 in the main body 111 , the main body 111 is connected to the first energy storage unit 220 through the connection between the connecting member 114 and the first energy storage unit 220 .

[0078] like Figure 7 , Figure 8 and Fig.10As shown, in some embodiments, optionally, the main body 111 also includes: a plurality of reinforcing ribs 115, wherein the two ends of any reinforcing rib 115 are respectively connected to the inner wall of the seat body 113 and the outer wall of the receiving groove 116, and the plurality of reinforcing ribs 115 are evenly distributed along the circumference of the receiving groove 116.

[0079] In this embodiment, the structure of the main body 111 is further defined. The main body 111 also includes a plurality of reinforcing ribs 115, which are used to improve the overall strength of the main body 111. Specifically, the seat body 113 is a groove structure, and there is a spacing between the inner wall of the seat body 113 and the outer wall of the receiving groove 116. The reinforcing ribs 115 are located between the inner wall of the seat body 113 and the outer wall of the receiving groove 116. The two ends of any reinforcing rib 115 are respectively connected to the inner wall of the seat body 113 and the outer wall of the receiving groove 116, and the plurality of reinforcing ribs 115 are evenly distributed along the circumference of the receiving groove 116. In this way, the wall surface of the seat body 113 can be supported by the reinforcing ribs 115, thereby improving the overall strength of the main body 111.

[0080] In some embodiments, optionally, the dimension of the end of the main body 111 connected to the buffer pad 112 is smaller than the dimension of the end of the main body 111 away from the buffer pad 112 .

[0081] In this embodiment, the shape of the main body 111 is limited. The main body 111 is close to a conical structure, and the size of the end of the main body 111 connected to the buffer pad 112 is smaller than the size of the end of the main body 111 away from the buffer pad 112. When the first guide member 110 is inserted into the second guide member 120, the end of the main body 111 connected to the buffer pad 112 is first inserted into the second guide member 120, that is, the end of the main body 111 with a smaller size is first inserted into the second guide member 120. In this way, the first guide member 110 can be inserted into the second guide member 120 more easily, reducing the difficulty of matching the first guide member 110 with the second guide member 120.

[0082] In some embodiments, optionally, when there are multiple second energy storage units 230, any two second energy storage units 230 among the multiple second energy storage units 230 are connected to each other, and the guide device 100 also includes: a third connecting member 234, which is used to connect to the second energy storage unit 230, and the second connecting member 233 is also used to insert the third connecting member 234 provided in the adjacent second energy storage unit 230; wherein, another part of the first guide members 110 among the multiple first guide members 110 are used to connect to the second energy storage unit 230, and the first guide member 110 connected to the second energy storage unit 230 is used to support the second energy storage unit 230, and in the process of connecting the two second energy storage units 230, the second connecting member 233 provided in one of the second energy storage units 230 is first inserted into the third connecting member 234 provided in the other second energy storage unit 230, and then the first guide member 110 provided in one of the second energy storage units 230 is inserted into the second guide member 120 provided in the other second energy storage unit 230.

[0083] In this embodiment, the guide device 100 is further limited. The number of the second energy storage units 230 can be multiple, and any two of the multiple second energy storage units 230 are connected to each other. The guide device 100 also includes a third connecting member 234. When the number of the second energy storage units 230 is multiple, the number of the third connecting members 234 is also multiple. The multiple third connecting members 234 are used to connect to the multiple second energy storage units 230. The second connecting member 233 is also used to insert the third connecting member 234 provided in the adjacent second energy storage unit 230. Another part of the first guide members 110 in the multiple first guide members 110 is connected to the second energy storage unit 230. The second connecting member 233, the third connecting member 234, the first guide member 110 and the second guide member 120 cooperate with each other to play a guiding and limiting role when the two second energy storage units 230 are connected.

[0084] Specifically, during the connection of the two second energy storage units, the second connecting member 233 provided at one of the second energy storage units 230 is first inserted into the third connecting member 234 provided at the other second energy storage unit 230 to achieve the preliminary positioning of the two second energy storage units 230. Then the first guide member 110 connected to one of the second energy storage units 230 is inserted into the second guide member 120 provided at the other second energy storage unit 230. The size of the first guide member 110 is close to that of the second guide member 120. When the first guide member 110 is inserted into the second guide member 120, there is a small gap between the first guide member 110 and the second guide member 120. In this way, the first guide member 110 and the second guide member 120 cooperate to achieve guidance and further limiting effects, thereby reducing the position deviation between the two second energy storage units 230 connected to each other.

[0085] Furthermore, the first guide member 110 provided on the second energy storage unit 230 also supports the second energy storage unit 230. Specifically, the first guide member 110 connected to the second energy storage unit 230 is located at the bottom of the second energy storage unit 230, so that the first guide member 110 has the function of supporting the second energy storage unit 230.

[0086] By connecting another part of the multiple first guide members 110 to the second energy storage unit 230, the second energy storage unit is guided and limited by the guide device 100, so that the user can directly connect the multiple second energy storage units 230 without using professional tools for operation, thereby improving user convenience.

In the process of connecting the first energy storage unit 220 with the second energy storage unit 230, the second connector 233 is first inserted into the first connector 223 to preliminarily position the first energy storage unit 220 and the second energy storage unit 230. Then, the first guide member 110 connected to the first energy storage unit 220 is inserted into the second guide member 120 provided in the second energy storage unit 230. The first energy storage unit 220 is guided and limited by the cooperation between the first guide member 110 and the second guide member 120 to reduce the position deviation between the first energy storage unit 220 and the second energy storage unit 230.

[0090] Furthermore, the first guide member 110 connected to the first energy storage unit 220 is arranged at the bottom of the first energy storage unit 220, so that the first guide member 110 also has the function of supporting the first energy storage unit 220. When the first guide member 110 is arranged on the first energy storage unit 220, there is no need to additionally set other supporting structures and guiding structures in the first energy storage unit 220. Only the first guide member 110 and the second guide member 120 can realize the support of the first energy storage unit 220 and the guide limit when the first energy storage unit 220 is connected to the second energy storage unit 230. In this way, the structure of the energy storage device 200 can be simplified, the production cost of the product can be reduced, and it is convenient for users to operate.

[0093] In this embodiment, the structures of the first energy storage unit 220 and the second energy storage unit 230 are defined. The first energy storage unit 220 includes a first shell 221, a first battery pack and a first connector 222, wherein the first battery pack is used for energy storage and is located in the first shell 221. The first connector 222 is connected to the first battery pack, and the first connector 222 is used to connect to the second energy storage unit 230, so that the first energy storage unit 220 is electrically connected to the second energy storage unit 230. Specifically, the first connector 223 of the guide device 100 is provided in the first shell 221, the first shell 221 is a groove, and the first connector 222 is located in the first connector 223, so as to protect the first connector 222.

[0094] Further, the second energy storage unit 230 includes a second shell 231, a second battery pack and a second connector 232. The second battery pack is used for energy storage, and the second battery pack is located in the second shell 231.
