It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] Example:

[0035] See also Figure 1-Figure 5 , an energy storage battery pack cluster frame, comprising a frame assembly 1 and a displacement drive mechanism 2;

[0036] The frame assembly 1 is provided with a placement position and a limit device, the placement position is used to place the energy storage battery pack 3, and the limit device corresponds to the position of the placement position;

[0037] The limiting device includes a limiting block 101 and an elastic member 102. The limiting block 101 is slidably matched with the frame assembly 1. The elastic member 102 is arranged at the matching position of the limiting block 101 and the frame assembly 1. The relative sliding direction of the limiting block 101 and the frame assembly 1 is perpendicular to the extension direction of the placement position.

[0038] The energy storage battery pack 3 is provided with a limiting groove 301 which can cooperate with the limiting block 101. When the limiting groove 301 cooperates with the limiting block 101, the elastic member 102 is in a squeezed state;

[0039] The displacement driving mechanism 2 includes a displacement driving bracket, a displacement driving device 201, a displacement driving connecting rod assembly and a driving component. The displacement driving bracket is arranged on the frame assembly 1, the displacement driving device 201 and the displacement driving connecting rod assembly are arranged on the displacement driving bracket, and the driving end of the displacement driving device 201 drives the component to move in the extension direction relative to the placement position through the displacement driving connecting rod assembly, and the driving component is detachably connected to the energy storage battery pack 3.

[0040] First, the frame assembly 1 of the present embodiment is provided with a limiting device. When the energy storage battery pack 3 is placed in the placement position of the frame assembly 1 and fixed to the frame assembly 1, the limiting groove 301 of the energy storage battery pack 3 cooperates with the limiting block 101. At the same time, the limiting device has an elastic member 102. The amount of compression of the elastic member 102 can be adjusted according to the size of the energy storage battery pack 3 to ensure the tightness of the matching structure between the energy storage battery pack 3 and the frame assembly 1, and to ensure the limiting effect of the frame assembly 1 on the energy storage battery pack 3. This can prevent the energy storage battery pack cluster rack from being displaced or collided during transportation due to the existing unreliable limiting structure and the existence of limiting gaps, thereby causing damage to the energy storage battery pack 3. At the same time, the elastic member 102 has a buffering effect. When the energy storage battery pack cluster rack is displaced during movement, it collides with the energy storage battery pack 3, causing damage to the energy storage battery pack 3.

[0041] Secondly, a displacement drive mechanism 2 is provided on the frame assembly 1 of this embodiment. In view of the problem that the existing battery pack cluster frame structure prevents operators from entering the cluster frame to operate, the displacement drive mechanism 2 can assist the operator to adjust the relative position of the energy storage battery pack 3 and the frame assembly 1, making it convenient for the operator to quickly locate and install the relative position of the energy storage battery pack 3 and the frame assembly 1.

[0042] The displacement drive mechanism 2 and the frame assembly 1 of this embodiment are detachably connected, for example, they are fixed by bolts. After the energy storage battery pack 3 is installed, the displacement drive mechanism 2 is removed to transport the energy storage battery pack cluster rack.

[0043] In this embodiment, the specific structure of the frame assembly 1 is as follows:

[0044] It includes a longitudinal frame group and a transverse frame group, wherein the longitudinal frame group is connected to the transverse frame group;

[0045] There are more than two longitudinal frame groups and they are evenly distributed along the extension direction of the placement position. The longitudinal frame groups include two longitudinal frame members 103. There are more than two transverse frame groups and they are evenly distributed along the extension direction of the longitudinal frame members 103. The transverse frame groups include two transverse frame members 104. Placement positions are formed between adjacent transverse frame groups.

[0046] The specific structure of the limiting device of this embodiment is as follows:

[0047] It also includes a limiting frame member 105, which is respectively connected to the longitudinal frame member 103 and the transverse frame member 104. A bending portion is provided at one end of the limiting frame member 105, and an installation portion 106 for installing the limiting block 101 is formed between the bending portion and the transverse frame member 104. The elastic member 102 is located in the installation portion 106.

[0048] Specifically, the limiting device also includes a limiting guide column 107, which is arranged on the mounting portion 106, the limiting block 101 is slidably matched with the limiting guide column 107, the elastic member 102 is sleeved on the limiting guide column 107, and the elastic member 102 is located between the bending portion and the limiting block 101.

[0049] Specifically, the limiting block 101 includes a limiting protrusion with a triangular cross section, the limiting protrusion has a limiting guide inclined surface, and the cross section of the limiting groove 301 is V-shaped.

[0050] In this embodiment, the limiting protrusion of the limiting block 101 protrudes from the mounting portion 106. When the energy storage battery pack 3 is placed in the placement position, the limiting protrusion cooperates with the limiting groove 301 through the limiting guide inclined surface. At this time, the elastic member 102 is in an extruded state, and the change in the length dimension tolerance of the energy storage battery pack 3 can be offset by the compression amount of the elastic member 102. The limiting guide inclined surface of the limiting protrusion has a guiding function, which can make the limiting protrusion cooperate with the limiting groove 301 smoothly. When the energy storage battery pack cluster frame moves with the energy storage battery pack 3 due to its displacement during the movement, the buffering effect of the limiting device on the energy storage battery pack 3 is guaranteed.

[0051] The elastic member 102 of this embodiment may be a spring member, a silicone foam, a spring steel sheet or other elastic structure member.

[0052] In this embodiment, the specific fixing structure of the energy storage battery pack 3 and the frame assembly 1 is as follows:

[0053] The limiting groove 301 is arranged at one end of the energy storage battery pack 3, and the other end of the energy storage battery pack 3 is provided with a fixing seat 302. The fixing seat 302 is provided with a fixing member 303 that can be connected to the frame assembly 1. The fixing member 303 can be fixedly connected by bolts and nuts.

[0054] The specific structure of the displacement driving mechanism 2 of this embodiment is as follows:

[0055] The displacement driving bracket is L-shaped, and includes a first displacement driving bracket component 202 and a second displacement driving bracket component 203, and the displacement driving device 201 is disposed on the first displacement driving bracket component;

[0056] The displacement drive connecting rod assembly includes a first connecting rod member 204, a second connecting rod member 205, a third connecting rod member 206, a fourth connecting rod member 207, a first rotating shaft member 208 and a second rotating shaft member 209. The first rotating shaft member 208 is rotationally matched with the first displacement drive bracket member 202, and the second rotating shaft member 209 is rotationally matched with the displacement drive bracket member. The two ends of the first rotating shaft member 208 are respectively hinged to the second connecting rod member 205 and the third connecting rod member 206. The two ends of the first connecting rod member 204 are respectively hinged to the driving end of the displacement drive device 201 and the second connecting rod member 205. One end of the third connecting rod member 206 is hinged to the driving component. The two ends of the fourth connecting rod member 207 are respectively connected to the driving component and the second rotating shaft member 209.

[0057] Specifically, the driving component includes a driving seat body 210, on which is provided a third rotating shaft member 211 which is rotatably matched therewith, one end of the third rotating shaft member 211 is hinged to one end of the third connecting rod member 206, and a hook member is provided at the bottom of the driving seat body 210, which is detachably connected to the energy storage battery pack 3.

[0058] Specifically, the displacement drive mechanism 2 is disposed on the longitudinal frame member 103 and is disposed above the placement position, specifically symmetrically disposed on both sides above the placement position. Meanwhile, the displacement drive device 201 of this embodiment can adopt a rotary drive motor.

[0059] The working principle of the displacement driving mechanism 2 of this embodiment is as follows:

[0060] The driving end of the displacement driving device 201 acts on the first connecting rod 204 to drive the second connecting rod 205 to rotate, and the second connecting rod 205 acts on the first rotating shaft 208 to drive the third connecting rod 206 to rotate. The third connecting rod 206 acts on the driving component to rotate relative to the second rotating shaft 209. At the same time, the matching structure between the third connecting rod 206 and the driving component is a structure in which one end of the third rotating shaft 211 is hinged to one end of the third connecting rod 206. In this way, it can be ensured that when the driving seat 210 rotates relative to the second rotating shaft 209, the bottom of the driving seat 210 can always move parallel to the placement position. At this time, the hook member on the driving seat 210 drives the energy storage battery pack 3 to move relative to the frame assembly 1. When the energy storage battery pack 3 is moved to the placement position, the connection structure of the hook member can be released. Moreover, because the displacement driving mechanism 2 is symmetrically arranged on both sides above the placement position, that is, the hook members on the driving seat body 210 are connected to both sides of the energy storage battery pack 3, the stability of the displacement driving mechanism 2 in the process of moving the energy storage battery pack 3 can be ensured.

[0061] In summary, the energy storage battery pack cluster rack of the present application solves the problem that the existing cluster rack lacks positioning and restriction of the battery pack due to the length dimension tolerance of the energy storage battery pack 3. Through the structure of the present application, the energy storage battery pack 3 and the frame assembly 1 can be closely matched to ensure the limiting effect of the frame assembly 1 on the energy storage battery pack 3, and the energy storage battery pack cluster rack can be prevented from being displaced or collided during transportation due to the existing limiting structure being unreliable and the existence of limiting gaps, thereby causing damage to the energy storage battery pack 3. At the same time, the elastic member 102 has a buffering effect, and when the energy storage battery pack cluster rack is displaced during movement and collides with the energy storage battery pack 3, causing damage to the energy storage battery pack 3, it also has better compatibility.

[0062] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
