[0063] Figure 1 is a perspective view of an energy storage cabinet according to an embodiment of the present embodiment, and includes: a cabinet body 1 having an accommodation space formed inside, a battery box body 2 installed in the accommodation space, a supporting member 3 provided on at least one side of the battery box body 2 along a first direction, and a limiting mechanism 4 installed on the inner wall of the cabinet body 1 beside the supporting member 3, the limiting mechanism 4 at least including: a support plate body 5 installed on the inner wall of the cabinet body 1 and slidingly connected with a push-pull member 8 along a second direction, a connecting rod mechanism 6 rotatably installed on the side of the support plate body 5 close to the battery box body 2 and connected with the push-pull member 8; a driving unit 7 provided on the end of the support plate body 5 close to the opening of the cabinet body 1 and connected with the push-pull member 8, the driving unit 7 being configured to drive the connecting rod mechanism 6 to rotate by driving the push-pull member 8 to move along the second direction; the first direction is configured as the length direction or the width direction of the battery box body 2, the second direction is configured as the installation direction of the battery box body 2, and the supporting member 3 is configured to have a top surface located on the rotating path of the connecting rod mechanism 6 for pressure bonding and fixing of the connecting rod mechanism 6.

[0064] Reference Figures 1-9In this arrangement, the energy storage cabinet described herein is provided with a supporting member 3 beside the battery box 2, which is convenient to be limited by the limiting mechanism 4 on one side thereof. Specifically, the supporting plate body 5 is installed on the inner wall of the cabinet 1 beside the battery box 2, so as to make full use of the gap between the battery box 2 and the cabinet 1, thereby reducing the influence on the internal space of the existing energy storage cabinet. The driving unit 7 is arranged on the supporting plate body 5 close to the opening end of the cabinet 1, so as to facilitate the operation of the driving unit 7 at the opening end of the cabinet 1. Thus, the driving unit 7 drives the connecting rod mechanism 6 to rotate, and drives the push-pull member 8 to slide along the second direction, and further drives the connecting rod mechanism 6 to rotate. Since the top surface of the supporting member 3 is located on the rotating path of the connecting rod mechanism 6, when the connecting rod mechanism 6 reaches the appropriate position, the connecting rod mechanism 6 can be pressed and connected to the top surface of the supporting member 3 to press and fix the supporting member 3. Therefore, the position of the battery box 2 in the energy storage cabinet can be limited in the height direction, and the position deviation of the battery box 2 can be effectively avoided, and the stability of the energy storage cabinet during transfer can be improved.

[0065] It should be noted that the limiting mechanism 4 is arranged on the inner wall of the cabinet 1 and does not interfere with the installation direction of the battery. In actual operation, the battery box 2 can be first sent into the cabinet 1 through the opening along the installation direction, and then the driving unit 7 can be operated at the opening end of the cabinet 1 by manual operation, so as to realize the rapid limiting of the supporting member 3 in the height direction. When the battery box 2 needs to be removed for maintenance or replacement, the driving unit 7 only needs to be operated from the opening, so as to realize the rapid release of the limiting of the supporting member 3. The structure is simple and the operation is convenient.

[0066] For example, the first direction can be the length direction of the battery box 2, or the width direction of the battery box 2. At this time, the actual installation of the battery box 2 can be adjusted, and the second direction is the direction of sending or taking out the battery box 2, so as to satisfy the supporting member 3 arranged on at least one side of the battery box 2 along the direction of sending or taking out the battery box 2, so as to realize the pressing and fixing of the supporting member 3 in the vertical direction.

[0067] The following will be described by way of example to introduce further specific implementation or refinement, improvement process of the board card plug-in box assembly, in order to further improve it, or for other aspects of improvement.

[0068] In one case of the embodiment, reference is made to Figure 9, the connecting rod mechanism 6 comprises: a first rod 61 rotatably connected to the support plate body 5 near the battery box 2 through a connecting member at the middle, a second rod 62 rotatably connected to the push-pull member 8 and the first rod 61 at both ends through connecting members, and a pressing member 63 arranged at the end of the first rod 61 away from the second rod 62, the pressing member 63 is configured to rotate with the first rod 61 to be pressed on the supporting member 3.

[0069] As can be seen, by arranging the first rod 61 and the second rod 62, it is convenient to connect with the push-pull member 8, so as to convert the horizontal movement of the push-pull member 8 sliding in the second direction into the rotation of the first rod 61 and the second rod 62 in the vertical direction, and the fulcrum effect at the middle position of the second rod 62 is used to cooperate with the first rod 61 to form a two-link structure, so as to drive the first rod 61 to flip up and down along the vertical plane, and then press the pressing member 63 on the supporting member 3, so as to realize the limiting of the battery box 2 in the vertical direction.

[0070] For example, the above-mentioned connecting rod mechanism 6 can also be selected according to the needs, such as a crank connecting rod mechanism, a crank rocker mechanism, or a crank slider mechanism, as long as it can transmit movement through the driving unit 7 and drive the pressing member 63 to rotate. The specific arrangement mode can be adjusted according to the needs, and the present embodiment is not limited in this regard.

[0071] Further, with reference to Figure 4 , Figure 5 , Figure 6 and Figure 7 , further comprising: a first slot 51 penetratingly arranged in the support plate body 5 in the thickness direction, the first slot 51 is configured to slide the connecting member at the connection of the first rod 61 and the second rod 62, and both ends of the first slot 51 are correspondingly formed with two emergency stop positions; when the connecting member moves to one of the two emergency stop positions, the pressing member 63 is pressed on the top surface of the supporting member 3 to fix it; when the connecting member moves to the other of the two emergency stop positions, the pressing member 63 is separated from the top surface of the supporting member 3 to release the fixation.

[0072] It can be seen that by arranging the first slot 51, the first rod 61 at the middle position can realize the rotation angle and limit position by the two emergency stop positions of the first slot 51, so as to limit the rotation angle of the first rod 61 within a suitable range, so as to correspond to the pressing and locking of the supporting member 3, and to release the locking and separation.

[0073] Exemplarily, the first slot 51 can be provided as an arc-shaped slot, and the connecting member is slidably connected thereto. Specifically, the arc range of the arc-shaped slot can be within 30 degrees to correspond to the rotation stroke of the first rod 61. Of course, the arc of the first slot 51 can be adjusted as needed, which is not specifically limited in the embodiment.

[0074] Further, referring to Figure 6 and Figure 7 , the support plate body 5 further comprises a limiting roller 64 fixed to the side of the first rod 61 away from the crimping member 63 and coaxial with the crimping member 63, and a second slot 52 provided at the lower end of the support plate body 5 and configured to slidably accommodate the limiting roller 64.

[0075] As can be seen, by coaxially installing the limiting roller 64 on the back of the crimping member 63, the limiting roller 64 is slidably accommodated in the second slot 52, so that the other end of the first rod 61 can rotate along the preset trajectory, further improving the stability of the rotation process of the first rod 61, and facilitating the stable crimping of the crimping member 63 on the top surface of the supporting member 3.

[0076] Exemplarily, the second slot 52 is provided as two arc-shaped slots corresponding to the two limit positions of the limiting roller 64, and also corresponding to the two limit positions of the crimping member 63. The specific shape and arc of the two arc-shaped slots can be adjusted according to the shape of the supporting member 3 to realize the abutment and adaptation therebetween, which is not specifically limited in the embodiment.

[0077] In actual operation, referring to Figure 3 , Figure 4 , Figure 5 and Figure 9 , the support plate body 5 comprises a first plate body 53 configured to be installed on the cabinet body 1, and a second plate body 54 attached to the side of the first plate body 53 close to the battery box 2. The second plate body 54 is provided with a guide portion 55 protruding towards the battery box 2, and the guide portion 55 is configured to extend in the second direction to slidably accommodate the push-pull member 8.

[0078] It can be seen that by providing the support plate body 5 as the first plate body 53 and the second plate body 54, the push-pull member 8 can be accommodated by the guide portion 55, thereby realizing the stable movement of the push-pull member 8 in the first direction. In addition, it also avoids the interference between the push-pull member 8 and the cabinet body 1 when the push-pull member 8 is installed close to the cabinet body 1, thereby improving the operation reliability of the push-pull member 8.

[0079] On this basis, referring to Figure 4 ,Figure 5 and Figure 9 Further comprising: a first guide slot 56 penetratingly arranged in the first plate body 53 and the second plate body 54 opposite to the guide portion 55, and a second guide slot 57 penetratingly arranged in the first plate body 53 and the second plate body 54, the first guide slot 56 is configured as at least one and extends along the first direction, and the second rod member 62 slides through the connecting member at one end of the first guide slot 56 away from the first rod member 61; the second guide slot 57 is arranged at one end of the support plate body 5 close to the entrance of the cabinet body 1 and is at the same height as the first guide slot 56.

[0080] As can be seen, through the first guide slot 56, the second rod member 62 and the push-pull member 8 are conveniently connected by the connecting member, and at the same time, the top end of the second rod member 62 makes a horizontal linear motion along the track of the first guide slot 56, thereby cooperating with the first rod member 61 to convert the horizontal motion of the push-pull member 8 into the rotation of the first rod member 61; the second guide slot 57 at the same height as the first guide slot 56 provides a basis for the movement of the driving unit 7 to drive the push-pull member 8.

[0081] In actual operation, the push-pull member 8 can be a push-pull rod or a push-pull shaft, and an opening is arranged in the thickness direction to pass through the connecting member, thereby realizing the connection with the connecting rod mechanism and the driving unit. The specific shape thereof can be adjusted as needed, which is not specifically limited in the present embodiment.

[0082] Further, referring to Figure 8 and Figure 9 The driving unit 7 comprises: a push-pull handle 71 configured to be rotatably installed in the inner wall of one end of the support plate body 5 close to the entrance of the cabinet body 1, and a guide slot 72 arranged at the top end of the push-pull handle 71 and having a certain included angle with the second guide slot 57; the connecting member connected with the push-pull member 8 is slidably installed in the guide slot 72 and passes through the second guide slot 57, and is configured to move along the guide slot 72 and the second guide slot 57 by rotating the push-pull handle 71 to drive the push-pull member 8 to reciprocate along the second direction.

[0083] It can be known that, by arranging the push-pull handle 71 at one end of the support plate body 5 close to the entrance of the cabinet body 1, the push-pull handle 71 can be operated at the entrance of the cabinet body 1, and by external force, the push-pull handle 71 is rotated to drive the connecting member in the guide slot 72 to move along the second guide slot 57, thereby driving the push-pull member 8 to move along the second direction.

[0084] Specifically, since the guide slot 72 has a predetermined length, the two ends of the guide slot 72 correspond to the two limit motion positions of the connecting member, and also correspond to the two limit positions of the connecting member in the second guide slot 57, which are used as the limit stroke positions of the push-pull member 8 reciprocating motion.

[0085] Exemplarily, the length of the guide notch 72 can be selected as required to correspond to the rotation limit angle of the push-pull handle 71, and the length of the second guide groove 57 corresponds to the stroke length of the push-pull member 8. The specific size and shape thereof can be selected as required, and are not specifically limited in the present embodiment.

[0086] Further, Figure 8 and Figure 9 The push-pull handle 71 comprises a handle portion 712 integrally connected to the mounting portion 711 and rotatably mounted to the support plate body 5 through a connecting member at an angle to the vertical direction, and the guide notch 72 is provided through the mounting portion 711 in the thickness direction. The handle portion 712 extends beyond the support plate body 5 in the first direction to be close to the opening end of the cabinet body 1.

[0087] It can be seen that the mounting portion 711 is provided to facilitate connection with the push-pull member 8, and the handle portion 712 is convenient for a person to hold to drive the push-pull handle 71 to rotate. The connecting member acts as a fulcrum to convert the rotary motion into linear motion of the push-pull member 8, so that the user is more labor-saving. The handle portion 712 extends beyond the support plate body 5 and is close to the opening of the cabinet body 1, which is convenient for the operator to operate directly at the opening of the cabinet body 1 without the need to put his hand into the cabinet body 1, and is more convenient to operate.

[0088] Exemplarily, the drive unit 7 can also be a pneumatic cylinder or a hydraulic cylinder provided on one side of the support plate body 5, or can also be a ball screw mechanism. Automatic driving equipment is used to realize the reciprocating motion of the push-pull member 8, and the present embodiment is not specifically limited.

[0089] In one case of the present embodiment, referring to Figure 3 It further comprises a supporting opening 31 provided in the top surface of the supporting member 3 and configured to be located on the rotation path of the crimping member 63 to abut the crimping member 63 inward.

[0090] It can be seen that the supporting opening 31 is provided in the top surface of the supporting member 3 to facilitate the abutment of the crimping member 63 inward to realize the fixation of the crimping member 63. Exemplarily, the supporting opening 31 can be a circular opening, and can also be an oval opening. The specific shape thereof is not specifically limited in the present embodiment.

[0091] Exemplarily, the supporting member 3 is configured as a supporting block, and / or the crimping member 63 is configured as a crimping wheel abutting inward of the supporting opening 31, and / or the connecting member is configured as a bolt and a limiting column connected with the bolt. Specifically, the crimping wheel can be configured as a PA roller.

[0092] In one case of the present embodiment, referring to Figure 8 andFigure 9 The support plate body 5 is provided with two connecting rod mechanisms 6 along the first direction, and the two connecting rod mechanisms 6 are configured to be distributed at two ends of the support plate body 5 in sequence.

[0093] It can be seen that by providing two connecting rod mechanisms 6 along the first direction of the support plate body 5, and correspondingly providing two supporting members 3 on one side of the battery box 2 at the two ends of the support plate body 5, the stability of the battery box 2 in the vertical direction is further improved.

[0094] In one case of the embodiment, referring to Figure 1 and Figure 2 Further comprising: support positions 11 which are sequentially and spacedly arranged along the height direction on the inner wall of the cabinet body 1 and are configured as multiple layers; and / or cabinet doors 12 which are movably connected to the cabinet body 1 on the outside of the opening and are configured to open or close the opening.

[0095] It can be seen that by providing support positions 11 which are spacedly arranged along the height direction, the battery box 2 can be arranged in layers along the height direction, and the opening can be opened and closed by the cabinet doors 12.

[0096] For example, the support positions 11 include two beam supports 111 which are symmetrically distributed on the inner walls on both sides of the cabinet body 1 along the width direction.

[0097] On this basis, the battery box 2 is provided with supporting members 3 on both sides along the width direction, and the limiting mechanisms 4 are installed on the inner walls on both sides of the cabinet body 1 along the width direction and are located between adjacent two layers of support positions 11.

[0098] It can be seen that by providing supporting members 3 on both sides of the battery box 2 along the width direction, the stability of the battery box 2 can be further improved, and by arranging the limiting mechanisms 4 between adjacent two layers of support positions 11, the limiting mechanisms 4 can be directly installed on the basis of the existing battery cabinet, without occupying other space of the cabinet body 1, and the practicability of the limiting mechanisms 4 is further improved.

[0099] The embodiment also provides an energy storage system, which includes at least one energy storage cabinet as described above.

[0100] It can be known that by applying the energy storage cabinet in the energy storage system, the driving unit 7 is arranged on the support plate body 5 close to the opening end of the cabinet body 1, which facilitates the operation of the driving unit 7 at the opening end of the cabinet body 1, so as to drive the connecting rod mechanism 6 to rotate by the driving unit 7, drive the push-pull component 8 to slide along the second direction, and further drive the connecting rod mechanism 6 to rotate; since the top surface of the supporting component 3 is located on the rotating path of the connecting rod mechanism 6, when the connecting rod mechanism 6 reaches the appropriate position, the connecting rod mechanism 6 can be crimped on the top surface of the supporting component 3 to crimp and fix the supporting component 3, so that the limiting of the battery box in the energy storage cabinet along the height direction can be realized, the possible position deviation of the battery box body 2 can be effectively avoided, and the stability in the transfer process of the energy storage cabinet is improved.

[0101] The above examples mainly illustrate the energy storage cabinet and the energy storage system including the same. Although only some embodiments of the present application are described, those skilled in the art should understand that the present application can be implemented in many other forms without departing from the spirit and scope of the present application. Therefore, the examples and embodiments shown are considered illustrative rather than limiting, and the present application can encompass various modifications and alternatives without departing from the spirit and scope of the technical solutions of the present application.
