[0001] This application relates to the technical field of energy storage power stations, and in particular to a battery installation device. Background Technology

[0002] In energy storage power stations, batteries are large in size and weight, requiring multiple personnel and lifting tools to work together during installation. Furthermore, as battery size continues to increase, battery installation is taking up more and more of the overall installation time, resulting in a larger and larger proportion of labor costs.

[0003] Existing battery installation methods involve setting multiple sets of guide rails and positioning components in the battery rack. The batteries are placed in the installation space using the guide rails and frame, and then positioned using the positioning components. This ensures the stability of the battery pack installation. However, the guide rails include limiting components and load-bearing components. The limiting components are located at the rear end of the load-bearing components and are connected to both of them by welding, threaded connections, etc. If the battery size is large, workers need to enter the rear end of the load-bearing components to install it, which is difficult.

[0028] Battery assembly labor costs are high. Batteries are large and heavy, and this trend is continuing. With the battery compartment size remaining constant, battery installation is taking up an increasingly larger portion of the overall installation time, resulting in a growing proportion of labor costs. Furthermore, worker safety risks are high during assembly. For long assemblies, workers must install the batteries inside the cabinet, posing safety risks when working under lifting equipment.

[0029] This application provides a battery fixing device. The following detailed description of the battery fixing device according to this embodiment is provided in conjunction with the accompanying drawings. Please refer to the drawings. Figures 1-3 As shown, the battery fixing device includes a mounting frame 1, an installation compartment 2 is disposed within the mounting frame 1, the installation compartment 2 extends through both ends of the mounting frame 1 along its length, and fixing channels 3 for installing batteries are provided on both sides of the installation compartment 2 along the width direction of the mounting frame 1; in this embodiment, the mounting frame 1 is composed of multiple horizontal and vertical bars connected together, and the fixing channels 3 may include a support portion extending into the mounting frame 1 along its width direction. The fixing channels 3 are fixedly installed on the mounting frame 1, the support portion is used to support the batteries to be installed, and the fixing channels 3 are arranged opposite to each other on the mounting frame 1. The installation compartment 2 is the battery installation space jointly formed by the mounting frame 1 and the fixing channels 3. No horizontal or vertical bars are provided on both sides of the mounting frame 1 along its length direction, so that the installation compartment 2 extends through both ends of the mounting frame 1 along its length direction; it should be noted that, in Figure 1 In the figure, the length direction of the mounting frame 1 is the first direction, the width direction of the mounting frame 1 is the second direction, and the height direction of the mounting frame 1 is the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0030] Fixing mechanisms 4 are provided on both sides of the mounting chamber 2 along the width direction of the mounting frame 1, allowing simultaneous fixation of the battery from both sides. The fixing mechanisms 4 are positioned above the fixing corridor 3, which supports the battery and limits its movement along the height direction of the mounting frame 1. The fixing mechanisms 4 are installed on the upper part of the fixing corridor 3 to facilitate battery fixation. Each fixing mechanism 4 includes a connecting rod assembly 41, a first limiting assembly 42, and an assisting assembly 43. Both the first limiting assembly 42 and the assisting assembly 43 are connected to the connecting rod assembly 41. A first mating part is provided on the side wall of the battery. The assisting assembly 43 drives the connecting rod assembly 41 to engage with the first limiting assembly 42 and the first mating part. In this embodiment, both the assisting assembly 43 and the connecting rod assembly 41 are connected to the mounting chamber 2. Specifically, both the assisting assembly 43 and the connecting rod assembly 41 are mounted on the mounting frame 1. Pulling the assisting assembly 43 can displace the connecting rod assembly 41. The first limiting assembly 42 is mounted on the connecting rod assembly 41. When the linkage assembly 41 is moved by the 43, the first limiting assembly 42 can be moved and moved to engage with the first mating part installed on the side wall of the battery. When installing the battery, the worker places the battery along the length of the mounting frame 1 from one side of the mounting compartment 2 onto the fixing corridor 3. After placement, the assisting assembly 43 drives the linkage assembly 41, which in turn drives the first limiting assembly 42. During the movement, the first limiting assembly 42 is inserted into the first mating part on the side wall of the battery, thus achieving fixed installation of the battery. This fixed installation method, by using the assisting assembly, eliminates the need to enter the battery carrying space for welding or other fixed installation when fixing the battery. The installation method is simple and easy to implement. Especially when installing large-sized batteries, it can reduce the risk of accidents and improve work safety. Furthermore, when fixing the battery, the fixing corridor 3 can limit the battery in the height direction of the mounting frame 1, and the first limiting assembly 42 can limit the side of the battery, fixing it from multiple sides and improving the stability of the fixed installation of the battery.

[0031] As a preferred option, refer to Figure 1 and Figure 2 Multiple installation compartments 2 are provided along the height direction of the installation frame 1. Each installation compartment 2 is equipped with a fixed corridor 3 and a fixing mechanism 4. Each installation compartment 2 can fix one battery, and multiple batteries can be fixed at the same time.

[0032] In this embodiment, refer to Figure 3The assist component 43 drives the connecting rod assembly 41 to move along the height direction of the mounting frame 1. The first limiting component 42 is a pin structure, and the first mating part is a fixed channel set on the surface of the battery. The fixed channel of the first mating part is set along the height direction of the mounting frame 1 so as to realize the insertion and mating of the first limiting component 42 and the first mating part. It should be noted that the assist component 43 can simultaneously drive the connecting rod assembly 41 and the first limiting component 42 to move in multiple directions, such as along the length direction of the mounting frame 1. At this time, the fixed channel of the first mating part is set according to the moving direction of the first limiting component 42 to ensure the fixed installation of the battery.

[0033] Reference Figure 3 The linkage assembly 41 includes a movable rod 411, a first transmission rod 412, and a second transmission rod 413 connected sequentially along the length of the mounting frame 1. Both the movable rod 411 and the second transmission rod 413 are connected to the mounting chamber 2. Both the first transmission rod 412 and the second transmission rod 413 are connected to the assist assembly 43. The first limiting assembly 42 is disposed on the movable rod 411.

[0034] In this embodiment, the movable rod 411, the first transmission rod 412, and the second transmission rod 413 are all movably connected, and one end of the movable rod 411 and the second transmission rod 413 are fixedly connected to the installation chamber 2. Both ends of the first transmission rod 412 are movably connected to the movable rod 411 and the second transmission rod 413. Therefore, the second transmission rod 413 is a movable component. The assist component 43 drives the second transmission rod 413 to move, which can drive the movable rod 411 to move. Furthermore, by setting the second transmission rod 413, the first transmission rod 412 can also be set in the installation chamber 2.

[0035] Reference Figure 4 The assist component 43 includes an eccentric disk 431, which is rotatably connected to the inner wall of the mounting chamber 2. The first transmission rod 412 and the second transmission rod 413 are both connected to the edge of the eccentric disk 431 away from the axis.

[0036] In this embodiment, the axis of the eccentric disk 431 is mounted on the mounting chamber 2, specifically fixed on the mounting frame 1, and the eccentric disk 431 can rotate along the axis. The first transmission rod 412 and the second transmission rod 413 are both mounted on the edge of the eccentric disk 431 away from the axis. The first transmission rod 412 and the second transmission rod 413 can be movably connected or fixedly connected. Since the mounting distance of the first transmission rod 412 and the second transmission rod 413 on the eccentric disk 431 is far from the axis, when the eccentric disk 431 rotates, it can drive the first transmission rod 412 and the second transmission rod 413 to move along the outer periphery of the eccentric disk 431. The eccentric disk 431 is set along the height direction of the mounting frame 1. Therefore, when the eccentric disk 431 rotates, the first transmission rod 412 can move along the height direction of the mounting frame 1, thereby realizing the insertion and engagement of the first limiting component 42 and the first mating part, and realizing the installation of the battery.

[0037] Reference Figure 3 The assist component 43 also includes a first limiting protrusion 432 and an elastic part 433. The side wall of the first transmission rod 412 is provided with a second limiting protrusion 412-1. One end of the elastic part 433 is connected to the first limiting protrusion 432, and the other end is connected to the second limiting protrusion 412-1. The first limiting protrusion 432 is located on the edge of the eccentric disk 431 away from the axis.

[0038] In this embodiment, the first limiting protrusion 432 is located on the edge of the eccentric disk 431 away from the axis and extends along the width direction of the mounting frame 1. The second limiting protrusion 412-1 is located on the side wall of the first transmission rod 412 and extends in the same direction as the first limiting protrusion 432. The elastic part 433 is a spring structure. One end of the elastic part 433 is fixed on the first limiting protrusion 432, and the other end of the elastic part 433 is installed on the second limiting protrusion 412-1. Through the elasticity of the elastic part 433, the first transmission rod 412 is moved on the one hand, and the stability of the movement is ensured on the other hand.

[0039] Reference Figure 4 The eccentric disk 431 is also provided with a third limiting protrusion 434. Multiple third limiting protrusions 434 are provided along the edge of the eccentric disk 431 away from the axis. The elastic part 433 presses against the upper or lower part of the third limiting protrusion 434 along the height direction of the mounting frame.

[0040] In this embodiment, the eccentric disk 431 is also provided with a plurality of third limiting protrusions 434, and the extension direction of the third limiting protrusions 434 is the same as the extension direction of the first limiting protrusions 432. The elastic part 433 is a long strip soft spring. During installation, the elastic part 433 forms an S-shape and presses against the upper or lower part of different third limiting protrusions 434 along the height direction of the mounting frame, thereby further ensuring the stability of movement.

[0041] Reference Figure 4 The assist component 43 also includes an extension 435, which is fixedly connected to the eccentric disk 431 and extends out of the eccentric disk 431.

[0042] In this embodiment, the extension 435 protrudes from the eccentric disk 431. The operator can rotate the eccentric disk 431 through the extension 435 to drive the movement of the movable rod 411. The extension 435 can extend in any direction according to the usage scenario so that the operator can apply force.

[0043] Reference Figure 4 The battery mounting device also includes a connecting structure 5, which is connected to the end of the second transmission rod 413 away from the first transmission rod 412. The connecting structure 5 includes a fixed stop 51 and a connecting rod 52. The fixed stop 51 is connected to the mounting chamber 2. The fixed stop 51 has a groove 511 extending along the length of the mounting frame 1. One end of the connecting rod 52 is slidably connected in the groove 511, and the other end is connected to the first transmission rod 412.

[0044] In this embodiment, the connecting structure 5 is used to fix the second transmission rod 413 inside the mounting compartment 2. The connecting structure 5 includes a fixing block 51 and a connecting rod 52. The fixing block 51 is fixedly connected to the mounting compartment 2, i.e., the mounting frame 1. Furthermore, the fixing block 51 has a groove 511 extending along the length direction of the mounting frame 1. The connecting rod 52 is slidably connected to the groove 511. Therefore, the position of the connecting rod 52 in the groove 511 can be adjusted as needed. The groove 511 is set along the length direction of the mounting frame 1. Therefore, the relative position of the connecting rod 52 in the length direction of the mounting frame 1 can be adjusted. The connecting rod 52 is connected to the first transmission rod 412. Thus, the relative position of the first transmission rod 412 in the length direction of the mounting frame 1 can be adjusted to accommodate batteries with different first mating positions.

[0045] Reference Figure 5 The first limiting component 42 includes a short transmission rod 421 and a limiting part 422. Multiple short transmission rods 421 are provided on the connecting rod assembly 41 along the length direction of the mounting frame 1. The limiting part 422 is connected to one end of the short transmission rod 421 and is inserted into the first mating part.

[0046] In this embodiment, the short transmission rod 421 connects the limiting part 422 and the movable rod 411 in the connecting rod assembly 41. Multiple short transmission rods 421 are provided on the connecting rod assembly 41 along the length direction of the mounting frame 1. Each short transmission rod 421 has a limiting part 422 installed at one end. The limiting part 422 is inserted and engaged with the first mating part, which facilitates the stability of the battery fixation when fixing a large-sized battery.

[0047] As a preferred embodiment, the limiting part 422 is provided with an inclined structure at the bottom along the height direction of the mounting frame 1. The inclined structure is provided at both ends of the limiting part 422 along the length direction of the mounting frame 1. When the limiting part 422 is inserted and engaged with the first mating part, the inclined structure contacts the first mating part first. Due to the setting of the inclined structure, the width of the limiting part 422 along the length direction of the mounting frame 1 gradually increases from bottom to top. By setting the inclined structure, the influence of small errors on the insertion and engagement between the first limiting component 42 and the first mating part is avoided.

[0048] Reference Figure 6 The fixing mechanism 4 also includes a second limiting component 44 and a second mating part 45. The second limiting component 44 is located at the end of the connecting rod assembly 41 away from the assist component 43. The second mating part 45 is movably connected to the mounting chamber 2. The second limiting component 44 and the second mating part 45 are inserted into each other. The second mating part 45 extends towards the battery along the width direction of the mounting frame 1.

[0049] In this embodiment, the second limiting component 44 is connected to the end of the connecting rod assembly 41 away from the assist component 43, and the second mating part 45 is fixed inside the mounting chamber 2, specifically mounted on the mounting frame 1. The second mating part 45 extends towards the battery along the width direction of the mounting frame 1 and is inserted into the second limiting component 44, which can fix the battery at both ends along the length direction of the mounting frame 1, further realizing multi-faceted fixation of the battery and ensuring the stability of the battery fixation.

[0050] Reference Figure 6 The second limiting component 44 includes an arc-shaped rod 441 and a fixing part 442. One end of the arc-shaped rod 441 is connected to the connecting rod assembly 41, and the other end is connected to the fixing part 442. The second mating part 45 includes an arc-shaped connector 451. The arc-shaped connector 451 is connected to the mounting chamber 2, and the arc-shaped rod 441 slides against the outer wall of the arc-shaped connector 451. When the arc-shaped rod 441 slides along the outer wall of the arc-shaped connector 451, it drives the fixing part 442 to move up and down along the height direction of the mounting frame 1.

[0051] In this embodiment, the fixing part 442 of the second limiting component 44 is connected to the connecting rod assembly 41 via an arc-shaped rod 441. The second mating part 45 includes an arc-shaped connector 451, the middle part of which is connected to the mounting chamber 2, specifically to the mounting frame 1. The arc-shaped rod 441 abuts against the outer wall of the arc-shaped connector 451. Preferably, the center of the arc-shaped rod 441 and the center of the arc-shaped connector 451 are located on both sides of the abutment point between the arc-shaped rod 441 and the arc-shaped connector 451. Since the abutment position is arc-shaped, when the connecting rod assembly 41 moves along the length direction of the mounting frame 1, the arc-shaped rod 441 moves along the length direction of the mounting frame 1 at the upper part of the arc-shaped connector 451. When the arc-shaped rod 441 moves towards the arc-shaped connector 451... When in motion, the arc-shaped rod 441 drives the fixing part 442 to move upward. When the arc-shaped rod 441 moves away from the arc-shaped connector 451, the arc-shaped rod 441 drives the fixing part 442 to move downward. When the arc-shaped rod 441 moves along the height direction of the mounting frame 1 above the arc-shaped connector 451, when the arc-shaped rod 441 moves upward, the arc-shaped rod 441 drives the fixing part 442 to move upward. When the arc-shaped rod 441 moves downward, the arc-shaped rod 441 drives the fixing part 442 to move downward. Therefore, regardless of whether the connecting rod assembly 41 moves along the length direction or the height direction of the mounting frame 1, the arc-shaped rod 441 can drive the fixing part 442 to move downward or upward. The second mating part 45 is set along the height direction of the mounting frame 1, which can realize the fixing of the battery.

[0052] As a preferred embodiment, the arc-shaped connector 451 includes a sliding bearing and a connector. The sliding bearing is sleeved around the periphery of the connector, and the arc-shaped connector 451 is connected to the mounting frame 1 through the connector. By setting the sliding bearing, the movement of the connector and the movement of the arc-shaped rod 441 do not affect each other. Furthermore, the second mating part 45 can be rotatably mounted on the mounting frame 1 without affecting the installation and removal of the battery. When the fixing part 442 is inserted and mated with the second mating part 45, the first limiting component 42 on the connecting rod assembly 41 is fixed with the first mating part of the battery. Therefore, the connecting rod assembly 41 is positioned, and the position of the second limiting component 44 is fixed, thereby limiting the second mating part 45 as well. While not affecting the movement of the battery, it can also limit the two side walls of the battery along the length direction of the mounting frame 1, preventing the battery from falling off the mounting frame 1 and further ensuring the stability of the battery installation.

[0053] Working principle of this embodiment: The battery installation device proposed in this utility model installs the battery in the installation frame 1. An installation compartment 2 is provided in the installation frame 1, penetrating both ends along the length direction of the frame 1. The battery is placed into the installation compartment 2 from one end of the installation frame 1 along the length direction for installation, and each installation compartment 2 can fix one battery. A fixing corridor 3 is provided in the installation compartment 2 for battery installation. After the battery enters the installation compartment 2, it is placed on the fixing corridor 3, which provides support for the battery. After the battery enters the installation compartment 2, the operator rotates the eccentric disk 431 through the extension 435. The rotation of the eccentric disk 431 drives the first transmission rod 412 to move along the length and height directions of the installation frame 1, causing the first limiting component 42 to engage with the first mating part, thus fixing the battery from both sides along the width direction of the installation frame 1. Furthermore, when the operator rotates the eccentric disk 431, the arc-shaped rod 441 in the second limiting component 44 located at one end of the connecting rod assembly 41 also moves along the length and height directions of the mounting frame 1. Since the arc-shaped rod 441 abuts against the arc-shaped connector 451, the displacement of the fixing part 442 in the length direction of the mounting frame 1 can be reduced, avoiding errors. In addition, the setting of the second limiting component 44 and the second mating part 45 limits and fixes the battery along the length direction of the mounting frame 1. The battery fixing device of this utility model not only simplifies the battery fixing and installation process by setting the fixing mechanism 4, avoiding the operator from entering the battery bearing area and reducing the danger, but also installs and fixes the battery in the length, width and height directions of the mounting frame 1. Through multi-faceted fixing of the battery, the stability of the battery fixing is further guaranteed.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
