Technical Field

[0003] This application pertains to battery storage device technology, specifically relating to an energy storage battery pack cluster frame and an energy storage battery pack installation method. Background Technology

[0004] With the rapid development of electric vehicles, renewable energy, and other fields, the demand for energy storage systems is increasing. Energy storage systems integrate a large number of lithium batteries into containers or cabinets for energy storage, peak shaving, valley filling, and frequency regulation. Battery pack racks are structures used to fix energy storage batteries. During use, to prevent displacement or collisions of the battery packs, limiting structures are needed to restrict their movement. Currently, battery pack racks are typically only fixed near the front end of the battery packs. Due to significant length tolerances in the battery pack housings and the inability of personnel to enter the racks for operation, there is a lack of positioning and restraint for the battery packs. The battery packs are heavy, and significant displacement or shaking during transportation poses a high risk. Therefore, an effective energy storage battery pack rack solution is needed to meet application requirements. Summary of the Invention

[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this application; the described embodiments are merely a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0032] Referring to Figures 1-5, an energy storage battery pack cluster frame includes a frame assembly 1 and a displacement drive mechanism 2;

[0033] The frame assembly 1 is provided with a placement position and a limiting device. The placement position is used to place the energy storage battery pack 3, and the limiting device corresponds to the position of the placement position.

[0034] The limiting device includes a limiting block 101 and an elastic element 102. The limiting block 101 is slidably engaged with the frame assembly 1, and the elastic element 102 is provided at the engagement point between the limiting block 101 and the frame assembly 1. The direction in which the limiting block 101 slides relative to the frame assembly 1 is perpendicular to the extension direction of the placement position.

[0035] The energy storage battery pack 3 is provided with a limiting groove 301 that 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 compressed state.

[0036] The displacement drive mechanism 2 includes a displacement drive bracket, a displacement drive device 201, a displacement drive linkage assembly, and a drive component. The displacement drive bracket is located on the frame assembly 1, and the displacement drive device 201 and the displacement drive linkage assembly are located on the displacement drive bracket. The drive end of the displacement drive device 201 drives the drive component to move in the extension direction relative to the placement position through the displacement drive linkage assembly. The drive component is detachably connected to the energy storage battery pack 3.

[0037] Firstly, the frame assembly 1 in this embodiment is equipped 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 element 102, which can adjust the amount of compression of the elastic element 102 according to the size of the energy storage battery pack 3, ensuring the tightness of the fit between the energy storage battery pack 3 and the frame assembly 1, and ensuring the limiting effect of the frame assembly 1 on the energy storage battery pack 3. This can prevent the energy storage battery pack 3 from being displaced or collided during transportation due to the unreliability of the existing limiting structure and the existence of limiting gaps, thus avoiding damage to the energy storage battery pack 3. At the same time, the elastic element 102 has a buffering effect. When the energy storage battery pack 3 is displaced during movement and collides with the energy storage battery pack 3, it will not cause damage to the energy storage battery pack 3.

[0038] Secondly, the frame assembly 1 in this embodiment is provided with a displacement drive mechanism 2. In view of the problem that the existing battery pack cluster structure makes it impossible for operators to enter the cluster for operation, the displacement drive mechanism 2 can assist the operator in adjusting the relative position of the energy storage battery pack 3 and the frame assembly 1, so that the operator can quickly position and install the relative position of the energy storage battery pack 3 and the frame assembly 1.

[0039] In this embodiment, the displacement drive mechanism 2 and the frame assembly 1 are detachable connection structures, for example, they are fixed by bolt connection. After the energy storage battery pack 3 is installed, the displacement drive mechanism 2 is removed to transport the energy storage battery pack cluster frame.

[0040] In this embodiment, the specific structure of the frame assembly 1 is as follows:

[0041] It includes longitudinal frame groups and transverse frame groups, with the longitudinal frame groups connected to the transverse frame groups;

[0042] There are two or more longitudinal frame groups, which are evenly distributed along the extension direction of the placement position. Each longitudinal frame group includes two longitudinal frame members 103. There are two or more transverse frame groups, which are evenly distributed along the extension direction of the longitudinal frame members 103. Each transverse frame group includes two transverse frame members 104. Placement positions are formed between adjacent transverse frame groups.

[0043] The specific structure of the limiting device in this embodiment is as follows:

[0044] It also includes a limiting frame 105, which is connected to the longitudinal frame 103 and the transverse frame 104 respectively. One end of the limiting frame 105 is provided with a bent part, and a mounting part 106 for installing the limiting block 101 is formed between the bent part and the transverse frame 104. The elastic member 102 is located in the mounting part 106.

[0045] Specifically, the limiting device also includes a limiting guide post 107, which is located on the mounting part 106. The limiting block 101 is slidably engaged with the limiting guide post 107, and the elastic element 102 is sleeved on the limiting guide post 107. The elastic element 102 is located between the bending part and the limiting block 101.

[0046] Specifically, the limiting block 101 includes a limiting protrusion with a triangular cross-section, the limiting protrusion having a limiting guide slope, and the limiting groove 301 having a V-shaped cross-section.

[0047] In this embodiment, the limiting protrusion of the limiting block 101 protrudes from the mounting part 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 slope. At this time, the elastic member 102 is in a compressed state. The change in the length dimension tolerance of the energy storage battery pack 3 can be offset by the compression of the elastic member 102. Moreover, the limiting guide slope of the limiting protrusion has a guiding function, which can make the limiting protrusion cooperate smoothly with the limiting groove 301. At the same time, when the energy storage battery pack cluster moves with the energy storage battery pack 3 due to displacement during the movement, the limiting device ensures the buffering effect of the limiting device on the energy storage battery pack 3.

[0048] The elastic element 102 in this embodiment can be a component with other elastic structures such as a spring, silicone foam, or spring steel sheet.

[0049] In this embodiment, the specific fixing structure between the energy storage battery pack 3 and the frame assembly 1 is as follows:

[0050] The limiting groove 301 is provided 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.

[0051] The specific structure of the displacement driving mechanism 2 in this embodiment is as follows:

[0052] The displacement drive bracket is L-shaped and includes a first displacement drive bracket 202 and a second displacement drive bracket 203. The displacement drive device 201 is disposed on the first displacement drive bracket.

[0053] The displacement drive linkage assembly includes a first link 204, a second link 205, a third link 206, a fourth link 207, a first pivot 208, and a second pivot 209. The first pivot 208 is rotatably engaged with the first displacement drive support 202, and the second pivot 209 is rotatably engaged with the displacement drive support. The two ends of the first pivot 208 are respectively hinged to the second link 205 and the third link 206. The two ends of the first link 204 are respectively hinged to the drive end of the displacement drive device 201 and the second link 205. One end of the third link 206 is hinged to the drive component. The two ends of the fourth link 207 are respectively connected to the drive component and the second pivot 209.

[0054] Specifically, the drive component includes a drive base 210, on which a third rotating shaft 211 is provided for rotational cooperation. One end of the third rotating shaft 211 is hinged to one end of the third connecting rod 206. A hook is provided at the bottom of the drive base 210, and the hook is detachably connected to the energy storage battery pack 3.

[0055] Specifically, the displacement drive mechanism 2 is located on the longitudinal frame member 103 and is positioned above the placement position, specifically symmetrically arranged on both sides above the placement position. Furthermore, the displacement drive device 201 in this embodiment can be a rotary drive motor.

[0056] The working principle of the displacement driving mechanism 2 in this embodiment is as follows:

[0057] 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. 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 cooperation structure between the third connecting rod 206 and the driving component is that one end of the third rotating shaft 211 is hinged to one end of the third connecting rod 206. This ensures 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 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 moves to the placement position, the connection structure of the hook can be released. Furthermore, because the displacement drive mechanism 2 is symmetrically positioned on both sides above the placement position, that is, the hooks on the drive base 210 are connected to both sides of the energy storage battery pack 3, the stability of the movement of the energy storage battery pack 3 by the displacement drive mechanism 2 can be guaranteed.

[0058] The embodiments of this application also disclose an installation method for an energy storage battery pack 3, applied to the above-mentioned energy storage battery pack cluster frame, including the following steps:

[0059] S1. Connect the energy storage battery pack 3 to the drive component of the displacement drive mechanism 2, and position the energy storage battery pack 3 above the placement position of the frame assembly 1.

[0060] S2. The energy storage battery pack 3 is brought to the placement position of the frame assembly 1 by the driving component of the displacement driving mechanism 2, and the limiting groove 301 of the energy storage battery pack 3 is made to cooperate with the limiting device.

[0061] S3. Fix the energy storage battery pack 3 to the frame assembly 1; and

[0062] S4. Separate the energy storage battery pack 3 from the drive component of the displacement drive mechanism 2.

[0063] In summary, the energy storage battery pack cluster rack and the energy storage battery pack 3 installation method of this application solve the problem that existing cluster racks lack positioning and restraint for the battery pack due to the length dimensional tolerance of the energy storage battery pack 3. The structure of this application enables a tight fit between the energy storage battery pack 3 and the frame assembly 1, ensuring the restraining effect of the frame assembly 1 on the energy storage battery pack 3. This avoids damage to the energy storage battery pack 3 caused by displacement or collision during transportation due to the unreliability of existing restraining structures and the existence of restraining gaps. Simultaneously, the elastic element 102 has a buffering effect, preventing damage to the energy storage battery pack 3 caused by collisions due to displacement of the energy storage battery pack cluster rack during movement, and also provides better compatibility.

[0064] The above description is merely some preferred embodiments of this application and does not constitute any limitation on this application. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the technical solution of this application shall still fall within the scope of the technical solution of this application.
