[0049] In a specific embodiment, the first driving assembly 40 includes a first screw motor 41, a first screw gear 42 and a rotating shaft 43. The rotating shaft 43 is fixed to the first end of the mounting bracket 30. The first screw gear 42 is fixed to the rotating shaft 43 (in a specific embodiment, the first screw gear 42 can be integrally connected with the rotating shaft 43). The first screw motor 41 is connected and used to drive the first screw gear 42 to rotate. The second driving assembly 50 includes an active bevel gear motor 51, a driven bevel gear 52, a lifting block 53, and a screw 54.

Among them, the two lifting blocks 53 are rotatably connected to the two ends of the rotating shaft 43 respectively, the driven bevel gear 52 and the bevel gear on the driving bevel gear motor 51 are meshed with each other, and the lower end of the screw rod 54 is matched with the circular hole provided at the lower end of the base of the cabinet 10. In the first driving assembly 40, the first screw motor 41 drives the first screw gear 42 to rotate, and further drives the rotating shaft 43 to rotate, and the driving shaft 43 is fixed on the mounting bracket 30, so that the mounting bracket 30 can follow the flip. In the two second driving assemblies 50 , the driving bevel gear motor 51 drives the driven bevel gear 52 , and the driven bevel gear 53 is fixed on the screw rod 54 , thereby driving the screw rod 54 to rotate, thereby forcing the lifting block 53 to move up and down along the axial direction of the screw rod 54 .

[0050] Slide grooves 12 are provided on both sides of the cabinet 10, and the slide grooves 12 are arranged along the direction of the screw rod 54. Both sides of the first end of the mounting bracket 30 are respectively located at positions corresponding to the slide grooves 12. Specifically, the first drive assembly 40 and the second drive assembly 50 are respectively arranged inside the two sides of the cabinet 10, and both ends of the rotating shaft 43 fixed to the first end of the mounting bracket 30 extend into the slide grooves 12 on both sides of the cabinet 10, so as to be fixedly connected with the first screw gear 42 and the lifting block 53.

[0051] Furthermore, the energy storage device in this embodiment also includes multiple third drive components 60. The cluster frame 20 is provided with a multi-layer frame, and the two sides of each layer of the frame are respectively connected with a third drive component 60. The third drive component 60 is used to drive the battery box 71 to be assembled to move into the cavity and abut and fix it on the frame.

[0052] Combination Figure 4 and Figure 7The third driving assembly 60 includes a second screw motor 61, a second screw gear 62, a driving gear 63, a driven gear 64 and a transmission rack 65. The driving gear 63 and the driven gear 64 are respectively arranged at the outer end and the inner end of the same side of the frame and are connected through the transmission rack 65. The driving gear 63 and the second screw gear 52 are coaxially connected. The second screw motor 61 is connected and used to drive the second screw gear 62 to rotate. Specifically, the driving gear 63 is arranged on the cluster frame 20 near the opening. The second screw motor 61 and the second screw gear 62 are meshed with each other. The second screw motor 61 can rotate forward and reverse to drive the second screw gear 62 to rotate. The second screw gear 62 drives the driving gear 63 coaxial therewith to rotate. The driving gear 63 then drives the driven gear 64 to rotate through the rack 65, so as to drive the rack 65 to rotate clockwise or counterclockwise, so as to drive the battery plug box 81 located thereon to move into the cavity 11.

[0053] The first screw motor 41, the driving bevel gear motor 51, and the second screw motor 61 are respectively controlled by corresponding buttons on the control panel 70 to rotate forward and reverse. Figure 8 As shown, the control panel 70 is provided with 14 button switches, namely, a first row second screw motor forward button 701, a first row second screw motor reverse button 702, a second row second screw motor forward button 703, a second row second screw motor reverse button 704, a third row second screw motor forward button 705, a third row second screw motor reverse button 706, a fourth row second screw motor forward button 707, a fourth row second screw motor reverse button 708, a fifth row second screw motor forward button 709, a fifth row second screw motor reverse button 710, an active bevel gear motor forward button 711, an active bevel gear motor reverse button 712, a first screw motor forward button 713, and a first screw motor reverse button 714.

[0055] like Figure 6As shown, a plurality of balls 31 arranged in an array are provided on the first surface of the mounting tray 30. By providing the balls 31 on the first surface of the mounting tray 30, the friction or resistance can be reduced, so that the mounting components (including the battery plug box 81, the high-voltage box 82, the PCS 83 and the liquid cooling unit 84, etc.) can be easily moved or rotated when placed thereon. From the free end of the mounting tray 30 to the fixed end (i.e., the first end) connected to the rotating shaft 43, the thickness of the mounting tray 30 becomes thicker and thicker; and in the second working position, the first surface of the mounting tray 30 is in a horizontal state. By setting the thickness of the fixed end of the mounting tray 30 to be thicker, the end edge of the fixed end of the mounting tray 30 can be made to abut against the edge of the side of the cabinet with an opening in the second working position, so that the weight of the entire mounting tray 30 and the mounting components placed thereon can be better supported, and the strength of the mounting tray 30 can also be increased. In the second working position, the end edge of the fixed end of the mounting bracket 30 connected to the rotating shaft 43 abuts against the edge of the side of the cabinet 10 having the opening.

[0056] like Figure 7 The cavity 11 includes an upper cavity 111 and a lower cavity 112. The cluster frame 20 is fixed to the upper cavity 111. The cluster frame 20 is used to assemble multiple battery boxes 81. The lower cavity 112 is used to assemble the control panel 70 and multiple installation components. The installation components include a high-voltage box 82, a PCS 83 and a liquid cooling unit 84.

[0057] The working process of the energy storage device of the preferred embodiment of the present invention is further described in detail below.

[0058] (1) The process of assembling the installation components (including the battery box 81, the high-voltage box 82, the PCS 83 and the liquid cooling unit 84)

[0059] A1: Before installation, the first surface of the mounting bracket 30 is set downward and abutted against the top of the cabinet 10, that is, the mounting bracket 30 is in the first working position. After the installation starts, the first screw motor reverse button 714 on the control panel 70 is pressed to turn the first screw motor 41 over, and then the screw of the first screw motor 41 is engaged with the first screw gear 42 fixed on the rotating shaft 43, driving the mounting bracket 30 fixed to the rotating shaft 43 to turn forward 180° until the thicker edge of the mounting bracket 30 abuts against the vertical edge in front of the cabinet 10 to form the second working position, thereby preventing the mounting bracket 30 from further rotating and playing a certain supporting role, and then stop pressing the first screw motor reverse button 714.

[0060] A2: Press the active bevel gear motor reverse button 712 on the control panel 70 to reverse the active bevel gear motor 51, and drive the driven bevel gear 52 through the bevel gear on the active bevel gear motor 51, and then drive the screw 54 to reverse, so that the lifting blocks 53 on the left and right sides move downward along the axial direction of the screw 54, thereby driving the rotating shaft 43 and the mounting bracket 30 fixed to the rotating shaft 43 to move downward to the bottom.

[0061] A3: Drag or lift the installation components to be assembled (battery box 81, high-voltage box 82, PCS 83 or liquid cooling unit 84) to the first surface of the mounting bracket 30 where the ball 31 is set, and then press the active bevel gear motor forward button 711 on the control panel 70 to make the active bevel gear motor 51 rotate forward, and the bevel gear on the active bevel gear motor 51 drives the driven bevel gear 52, and then drives the screw 54 to rotate forward, so that the lifting blocks 53 on the left and right sides move up along the axial direction of the screw 54, thereby driving the rotating shaft 43 and the mounting bracket 30 fixed to the rotating shaft 43 and the installation components placed on the ball 31 of the mounting bracket 30 to move upward to the horizontal position of the corresponding cabinet 10 installation position.

[0062] A4: Push the battery box or non-battery box into their respective installation positions;

[0063] First, the installation components (high-voltage box 82, PCS 83 and liquid cooling unit 84) of the non-battery plug-in box are assembled, and the installation components (high-voltage box 82, PCS 83 or liquid cooling unit 84) are pushed gradually close to the installation position of the lower cavity 112 of the corresponding cabinet 10, and then the installation components (high-voltage box 82, PCS 83 and liquid cooling unit 84) are pushed into the installation position of the lower cavity 112; reciprocating in sequence, all the installation components (high-voltage box 82, PCS 83 and liquid cooling unit 84) are installed in the installation position of the lower cavity 112 of the cabinet 10. Since a plurality of balls 31 arranged in an array are provided on the first surface of the mounting bracket 30, it is very easy and labor-saving to push the installation components (high-voltage box 82, PCS 83 and liquid cooling unit 84).

[0064] Then the battery box 81 is assembled, and the battery box 81 is pushed gradually to the upper end of the transmission rack 65 in the installation position of each layer of the cluster frame 20 in the corresponding cabinet 10, and then the first row second screw motor forward button 701 on the control panel 7 is pressed, and the second screw motors 61 on the left and right sides drive the second screw gear 62 meshing with the screw through the screw, and then drive the driving gear 63 coaxial with the second screw gear 62 to rotate forward, and further drive the battery box 81 placed on the front side above the transmission rack 65 to run into the upper cavity 111 of the cabinet 10 until the battery box 81 is engaged in place, that is, stop pressing the first row second screw motor forward button 701, so far, the first row of battery boxes 81 are installed to the corresponding installation position on the cluster frame 20 in the cabinet 10; reciprocate in sequence, and gradually complete the installation of the second row, third row, fourth row and fifth row of battery boxes 81 on the cluster frame 20 in the cabinet 10. The first to fifth rows are counted from bottom to top. In this embodiment, the installation is from bottom to top, and the subsequent disassembly can be carried out from bottom to top, so as to ensure that the center of gravity will not be offset. The battery plug box 81 does not need to be pushed in or pulled out manually. It only needs to place one foot of the battery plug box 81 against the upper edge of the transmission rack 65 to control the second screw motor 61 to rotate forward or reverse to send it to the corresponding installation position.

[0065] A5: After the installation is completed, press the active bevel gear motor forward button 711 on the control panel 70 to make the active bevel gear motor 51 rotate forward, and the bevel gear on the active bevel gear motor 51 drives the driven bevel gear 52, and then drives the screw 54 to rotate forward, so that the lifting blocks 53 on the left and right sides move upward along the axial direction of the screw 54, thereby driving the rotating shaft 43 and the mounting bracket 30 fixed to the rotating shaft 43 to move upward; when the rotating shaft 43 and the mounting bracket 30 move to the top position, stop pressing the active bevel gear motor forward button. Button 711, at this time, the first screw motor forward button 713 on the control panel 70 is pressed to make the first screw motor 41 rotate forward, and then the screw on the first screw motor 41 is engaged with the first screw gear 42 fixed on the rotating shaft 43, driving the mounting bracket 30 fixed to the rotating shaft 43 to flip backward 180° until the mounting bracket 30 is fitted with the left and right support blocks 13 on the cabinet 10, and then stop pressing the first screw motor forward button 713, at this point, the mounting bracket 30 is placed on the top of the cabinet 10.

[0066] (2) The process of disassembling the installed components (including the battery box 81, the high-voltage box 82, the PCS 83 and the liquid cooling unit 84)

[0067] B1: Before disassembly, the first surface of the mounting bracket 30 is set downward and abutted against the top of the cabinet 10, that is, the mounting bracket 30 is in the first working position. After disassembly begins, the first screw motor reverse button 714 on the control panel 70 is pressed to reverse the first screw motor 41, and then the mounting bracket 30 fixed to the rotating shaft 43 is driven to flip forward 180° through the engagement of the screw on the first screw motor 41 with the first screw gear 42 fixed on the rotating shaft 43 until the thicker edge of the mounting bracket 30 abuts against the vertical edge in front of the cabinet 1 to form the second working position, thereby preventing the mounting bracket 30 from further rotating. And it plays a certain supporting role, stop pressing the first screw motor reverse button 714.

[0068] B2: Press the active bevel gear motor reverse button 712 on the control panel 70 to reverse the active bevel gear motor 51, and drive the driven bevel gear 52 through the bevel gear on the active bevel gear motor 51, and then drive the screw 54 to reverse, so that the lifting blocks 53 on the left and right sides move downward along the axial direction of the screw 54, thereby driving the rotating shaft 43 and the mounting bracket 30 fixed to the rotating shaft 43 to move downward to the horizontal position of the mounting component to be disassembled.

[0069] B3: Move the battery box or non-battery box to the mounting tray 30;

[0070] The battery box 81 is removed first, and the fifth row second screw motor reverse button 710 on the control panel 70 is pressed. The second screw motors 61 on the left and right sides drive the second screw gears 62 meshing with the screws through the screws, and then drive the driving gears 63 coaxial with the second screw gears 62 to reverse, and further drive the battery box 81 placed on the upper end of the transmission rack 65 to move outside the cabinet 10 until the battery box 81 is completely located above the ball 31 on the first side of the mounting bracket 30.
