[0040] As Figures 1 to 4As shown in the figure, an embodiment of the present application provides a loading and unloading device 100 for carrying an energy storage device. The energy storage device includes an energy storage device 200 and a support member 300 disposed at the bottom of the energy storage device 200. The loading and unloading device 100 includes a transfer mechanism 110 and a base 120.

[0041] Among them, the transfer mechanism 110 includes a fixing component 111 and a support component 112. The support component 112 is rotatably disposed on the fixing component 111. The base 120 includes a first base body 121 and a second base body 122 that are spaced apart from each other. The first base body 121 and the second base body 122 jointly define an avoidance space 1211. The transfer mechanism 110 is respectively disposed on the first base body 121 and the second base body 122. The support component 112 is used to rotate relative to the fixing component 111 in a direction away from the avoidance space 1211 to avoid the support member 300 or rotate relative to the fixing component 111 in a direction close to the avoidance space 1211 to a preset angle to carry the support member 300.

[0042] It should be noted that the support component 112 can rotate relative to the fixing component 111 in a direction close to the avoidance space 1211 under its own gravity, or can be driven by an external force to rotate relative to the fixing component 111 in a direction close to the avoidance space 1211.

[0043] It can be understood that when the energy storage device 200 needs to be installed, the energy storage device 200 is moved to the position of the avoidance space 1211 by an automatic transportation tool, and then the energy storage device 200 is driven to move upward. During the upward movement, the support member 300 at the bottom of the energy storage device 200 contacts the support component 112 and drives the support component 112 to rotate in a direction away from the avoidance space 1211 until the support member 300 at the bottom of the energy storage device 200 disengages from the support component 112. At this time, the support component 112 can rotate in a direction close to the avoidance space 1211 to a preset angle, and then the automatic transportation tool drives the energy storage device 200 to move downward until the support component 112 carries the support member 300 at the bottom of the energy storage device 200. At this time, the installation of the energy storage device 200 is completed. When the energy storage device 200 needs to be disassembled, the energy storage device 200 can be driven to move upward by an automatic transportation tool to disengage from the support component 112. Through the loading and unloading device 100 provided in this embodiment, the loading and unloading of the energy storage device 200 is facilitated, thus properly solving the problem of inconvenient loading and unloading of the energy storage device 200 when transporting the energy storage device 200 by an automatic transportation tool.

[0044] As Figure 3 and Figure 4 shown, in one embodiment, a limiting post 113 is disposed on a side of the support component 112 facing away from the fixing component 111. The limiting post 113 is used to pass through a limiting hole 320 opened on the support member 300.

[0045] It can be understood that when the support assembly 112 rotates relative to the fixed assembly 111 towards the direction close to the avoidance space 1211 to a preset angle, the energy storage device 200 can be driven by an automatic transport tool to move downward, so that the limit post 113 is aligned with the limit hole 320 and passes through it until the support assembly 112 bears the support member 300 at the bottom of the energy storage device 200. At this time, the installation of the energy storage device 200 is completed.

[0046] In this embodiment, by providing the limit post 113 to pass through the limit hole 320 on the support member 300, the relative movement of the energy storage device 200 with respect to the loading and unloading device 100 can be restricted, reducing the possibility of accidental slipping of the energy storage device 200.

[0047] As Figure 4 shown, further, the limit post 113 is a cylinder with a diameter of d, and the limit hole 320 is a circular hole with a diameter of D, satisfying: 0.4 ≤ d / D ≤ 0.8.

[0048] Exemplarily, d / D can be selected as any value among 0.4, 0.45, 0.5, 0.56, 0.58, 0.6, 0.62, 0.65, 0.68, 0.7, 0.73, 0.76, and 0.8, or any value within the range composed of any two of them, and no specific limitation is made here.

[0049] It should be noted that if d / D is too small, that is, the diameter of the limit post 113 is relatively too small and the diameter of the limit hole 320 is relatively too large, then the limit post 113 cannot well restrict the movement of the energy storage device 200, increasing the risk of accidental slipping of the energy storage device 200. If d / D is too large, that is, the diameter of the limit post 113 is relatively too large and the diameter of the limit hole 320 is relatively too small, then when installing the energy storage device 200, it is difficult for the limit post 113 to be inserted into the limit hole 320, increasing the installation difficulty of the energy storage device 200. And after insertion, when disassembling the energy storage device 200, the limit post 113 is prone to contact interference with the support member 300, thus affecting the disassembly of the energy storage device 200, and this will reduce the loading and unloading efficiency of the energy storage device 200.

[0050] In this embodiment, by controlling d / D within the range of 0.4 to 0.8, that is, the diameter d of the limit post 113 is 40% - 80% of the diameter D of the limit hole 320, on the basis of reducing the possibility of the energy storage device 200 slipping, the influence on the loading and unloading efficiency of the energy storage device 200 is also reduced.

[0051] In another embodiment, a limiting hole 320 is provided on one side of the support assembly 112 away from the fixing assembly 111, and the limiting hole 320 is used to pass the limiting column 113 provided on the support member 300. This can also limit the movement of the energy storage device 200, thereby reducing the possibility of accidental slipping of the energy storage device 200.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, the switching mechanism 110 further includes an elastic member 114, which is respectively connected to the fixing assembly 111 and the supporting assembly 112, and is used to drive the supporting assembly 112 to rotate relative to the fixing assembly 111 to a preset angle in a direction close to the avoidance space 1211.

[0053] In this embodiment, since the elastic member 114 is respectively connected to the fixing assembly 111 and the supporting assembly 112, after the supporting member 300 at the bottom of the energy storage device 200 moves upward from the position of the avoidance space 1211 and separates from the supporting assembly 112, the elastic member 114 can apply an elastic force to the supporting assembly 112 to drive the supporting assembly 112 to rotate relative to the fixing assembly 111 in a direction close to the avoidance space 1211, so that the supporting assembly 112 can subsequently carry the supporting member 300 at the bottom of the energy storage device 200.

[0054] like Figure 5 and Figure 6 As shown, further, the transfer mechanism 110 also includes a rotating shaft 115, which is respectively passed through the fixed component 111 and the supporting component 112, and the supporting component 112 is rotatably connected with the fixed component 111 through the rotating shaft 115. The elastic member 114 is a torsion spring arranged on the rotating shaft 115, one end of the torsion spring is connected to the fixed component 111, and the other end of the torsion spring is connected to the supporting component 112.

[0055] In this embodiment, the setting of the rotating shaft 115 not only realizes the rotational connection between the fixing component 111 and the supporting component 112, but also facilitates the installation of the torsion spring. The torsion spring is sleeved on the rotating shaft 115, which can save the space occupied by parts and make the structure of the loading and unloading device 100 more compact.

[0056] Of course, for the above embodiment, the elastic member 114 can also be a spring sheet. By connecting the spring sheet between the support component 112 and the fixed component 111, it is also possible to apply elastic force to the support component 112 to drive the support component 112 to rotate in the direction of the avoidance space 1211. No specific restrictions are made on the type of the elastic member 114.

[0057] like Figure 5 , Figure 7 and Figure 8As shown, in one embodiment, the fixing component 111 includes a fixing plate 1111, a first connecting member 1112, and a first limiting member 1113. The first connecting member 1112 and the first limiting member 1113 are respectively disposed on the side of the fixing plate 1111 facing away from the base 120. The supporting component 112 includes a supporting plate 1121, a second connecting member 1122, and a second limiting member 1123. The second connecting member 1122 and the second limiting member 1123 are respectively disposed on the side of the supporting plate 1121 facing the base 120. The second connecting member 1122 is rotatably connected to the first connecting member 1112. When the supporting component 112 rotates relative to the fixing component 111 to a preset angle in the direction close to the avoidance space 1211, the second limiting member 1123 abuts against the first limiting member 1113.

[0058] In this embodiment, through the mutual abutment of the first limiting member 1113 and the second limiting member 1123, the angle of rotation of the supporting component 112 relative to the fixing component 111 in the direction close to the avoidance space 1211 can be limited, so that the supporting component 112 can rotate to a preset angle to support the support member 300 at the bottom of the energy storage device 200.

[0059] As Figures 3 to 5 shown, further, a first chamfered portion 11211 is provided at the edge of the side of the supporting plate 1121 facing the base 120. The first chamfered portion 11211 is used for surface contact with a second chamfered portion 330 provided at the edge of the side of the support member 300 close to the energy storage device 200.

[0060] In this embodiment, since a first chamfered portion 11211 is provided at the edge of the side of the supporting plate 1121 facing the base 120, and a second chamfered portion 330 is provided at the edge of the side of the support member 300 close to the energy storage device 200, in the process of the energy storage device 200 moving upward from the position of the avoidance space 1211, the first chamfered portion 11211 can be in surface contact with the second chamfered portion 330, avoiding the knocking damage caused by line contact or point contact between the support member 300 and the supporting plate 1121.

[0061] It should be noted that for the above embodiment, elastic portions, such as silicone, rubber, sponge, etc., can also be provided at the edges of the supporting plate 1121 and the support member 300 respectively. Through the buffer contact of the elastic portions, the knocking damage between the support member 300 and the supporting plate 1121 can also be avoided.

[0062] As Figure 5 、 Figure 7 and Figure 8As shown, further, the first connecting member 1112 includes a first connecting portion 11121 and a second connecting portion 11122 which are arranged at intervals, the second connecting member 1122 includes a third connecting portion 11221 and a fourth connecting portion 11222 which are arranged at intervals, the third connecting portion 11221 is located between the first connecting portion 11121 and the second connecting portion 11122, the second connecting portion 11122 is located between the third connecting portion 11221 and the fourth connecting portion 11222, the switching mechanism 110 also includes a rotating shaft 115, the rotating shaft 115 is respectively passed through the first connecting portion 11121, the second connecting portion 11122, the third connecting portion 11221 and the fourth connecting portion 11222, the third connecting portion 11221 is rotatably connected to the first connecting portion 11121 via the rotating shaft 115, and the fourth connecting portion 11222 is rotatably connected to the second connecting portion 11122 via the rotating shaft 115.

[0063] In this embodiment, since the third connection part 11221 is located between the first connection part 11121 and the second connection part 11122, and the second connection part 11122 is located between the third connection part 11221 and the fourth connection part 11222, the rotating shaft 115 is respectively penetrated through the first connection part 11121, the second connection part 11122, the third connection part 11221 and the fourth connection part 11222, that is, the first connection part 11121, the second connection part 11122, the third connection part 11221 and the fourth connection part 11222 are cross-arranged along the axial direction of the rotating shaft 115, thereby reducing the space occupied by the fixing component 111 and the supporting component 112, thereby making the structure of the loading and unloading device 100 more compact.

[0064] like Figure 5 and Figure 7 As shown, in a specific embodiment, the first limiting member 1113 includes a first limiting portion 11131 and a first elastic portion 11132. The first limiting portion 11131 is arranged on the side of the fixed plate 1111 away from the base 120, and the first elastic portion 11132 is arranged at an end of the first limiting portion 11131 away from the fixed plate 1111, for abutting against the second limiting member 1123.

[0065] Exemplarily, the first elastic part 11132 is a structure having an elastic buffering effect such as a silicone element, a rubber element, a sponge layer, etc. The second elastic part 11232 mentioned below may also adopt the above structure, which will not be described in detail later.

[0066] In this embodiment, since the first limiting member 1113 includes a first limiting portion 11131 and a first elastic portion 11132, the first limiting portion 11131 is disposed on the side of the fixing plate 1111 facing away from the base 120, and the first elastic portion 11132 is disposed at one end of the first limiting portion 11131 away from the fixing plate 1111. In this way, when the support assembly 112 rotates relative to the fixing assembly 111 towards the avoidance space 1211 by a preset angle, the first elastic portion 11132 abuts against the second limiting member 1123, which not only limits the rotation angle of the support assembly 112, but also avoids the rigid contact between the first limiting member 1113 and the second limiting member 1123, reducing the possibility of component damage.

[0067] As Figure 5 and Figure 8 shown, in another specific embodiment, the second limiting member 1123 includes a second limiting portion 11231 and a second elastic portion 11232. The first limiting portion 11131 is disposed on the side of the support plate 1121 facing the base 120, and the second elastic portion 11232 is disposed at one end of the second limiting portion 11231 away from the support plate 1121 for abutting against the first limiting member 1113. In this way, the rigid contact between the first limiting member 1113 and the second limiting member 1123 can also be avoided.

[0068] As Figure 5 , Figure 7 and Figure 8 shown, in yet another specific embodiment, the first limiting member 1113 includes a first limiting portion 11131 and a first elastic portion 11132. The first limiting portion 11131 is disposed on the side of the fixing plate 1111 facing away from the base 120, and the first elastic portion 11132 is disposed at one end of the first limiting portion 11131 away from the fixing plate 1111 for abutting against the second limiting member 1123. The second limiting member 1123 includes a second limiting portion 11231 and a second elastic portion 11232. The first limiting portion 11131 is disposed on the side of the support plate 1121 facing the base 120, and the second elastic portion 11232 is disposed at one end of the second limiting portion 11231 away from the support plate 1121 for abutting against the first limiting member 1113.

[0069] In this embodiment, by simultaneously providing the first elastic portion 11132 and the second elastic portion 11232, when the support assembly 112 rotates relative to the fixing assembly 111 towards the avoidance space 1211 by a preset angle, the first elastic portion 11132 abuts against the second elastic portion 11232, which can achieve a better elastic buffering effect, thus more effectively avoiding the rigid contact between the first limiting member 1113 and the second limiting member 1123.

[0070] As Figures 1 to 3As shown, in one embodiment, a plurality of transfer mechanisms 110 are disposed at intervals on the first base body 121 and the second base body 122 , respectively, and the support member 300 includes a plurality of support beams 310 , and the plurality of support beams 310 are disposed at intervals at the bottom of the energy storage device 200 .
