Description

Technical Field

[0001] This utility model relates to the field of battery pack assembly technology, and specifically to a battery pack assembly device. Background Technology

[0002] With the widespread application of new energy technologies, the demand for customized battery packs is increasing, especially in non-standardized scenarios such as small-scale custom production, laboratory prototype assembly, and cell replacement during maintenance and repair. In these cases, it is often necessary to assemble and fix multiple cells in a specific row and column arrangement (such as three rows and five columns, four rows and six columns, etc.).

[0003] Traditional assembly equipment typically uses modular card sets to combine battery cells, inserting each cell individually into the card slots of the modular card set to form a battery pack of fixed specifications. However, because modular card sets are generally manufactured according to standard specifications, it is difficult to customize the battery pack specifications, resulting in poor adaptability.

[0004] Furthermore, to improve the flexibility of battery pack assembly, existing technologies have developed assembly equipment that can be adjusted by sliding. By moving the position of the side panels or partitions, the size of the assembly area can be changed to customize the assembly of battery packs of different specifications.

[0005] However, in practical use, this type of equipment generally relies on the adjustment method of displacement caused by bolt rotation. This stepless adjustment characteristic makes its adjustment efficiency low. Especially for common standard specifications, the entire process adjustment still needs to be repeated, and it is impossible to achieve rapid switching. Utility Model Content

[0006] The purpose of this invention is to provide a battery pack assembly device to solve the technical problem of low adjustment efficiency caused by adjusting the size of the assembly area by rotating bolts in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0008] A battery pack assembly device includes a fixed horizontal plate and a fixed vertical plate arranged perpendicularly to each other. The fixed horizontal plate is provided with a horizontal sliding groove, and multiple locking ball structures are linearly arrayed in the horizontal sliding groove. A movable vertical plate is slidably arranged in the horizontal sliding groove, and a docking groove is provided on the movable vertical plate to match and engage with the locking ball structures.

[0009] The movable longitudinal plate and the fixed longitudinal plate are arranged in parallel. The movable longitudinal plate and the fixed longitudinal plate are provided with longitudinal sliding grooves on their opposite surfaces. Multiple locking ball structures are linearly arrayed in the longitudinal sliding grooves. A connecting rod is provided in the longitudinal sliding grooves. The connecting rod is provided with a connecting groove that matches and engages with the locking ball structure. The connecting rod is limited and slidably connected to the longitudinal sliding groove.

[0010] The connecting rod is connected to the telescopic push plate, which is arranged parallel to the fixed horizontal plate. The fixed vertical plate, the fixed horizontal plate, the movable vertical plate, and the telescopic push plate together form an assembly area.

[0011] As a preferred embodiment of this utility model, an mounting plate is fixedly provided at the ends of the movable longitudinal plate and the fixed longitudinal plate away from the fixed transverse plate. A through hole is provided on the mounting plate, and a sliding rod is axially slidably arranged in the through hole. The body of the sliding rod is connected to the connecting rod, and the end of the sliding rod is connected to the telescopic push plate.

[0012] As a preferred embodiment of this utility model, the slide rod includes an outer rod, a fixing ring, and an inner push rod. The outer rod is axially slidably disposed in the through hole, and the connecting rod is fixedly disposed on the outer rod.

[0013] The fixing ring is coaxially fixed inside the outer sleeve rod, the inner push rod is coaxially threadedly connected to the fixing ring, and the end of the inner push rod is fixedly connected to the telescopic push plate.

[0014] As a preferred embodiment of this utility model, the movable longitudinal plate has a linear groove on the side facing the assembly area, a transverse push plate is embedded in the linear groove, the transverse push plate is disposed below the longitudinal sliding groove, and a stud is rotatably disposed on the transverse push plate, the stud is connected to the middle of the movable longitudinal plate by thread engagement.

[0015] There is a clearance between the end of the telescopic push plate and the surface of the movable longitudinal plate, and the stud pushes the transverse push plate to move within the clearance.

[0016] As a preferred embodiment of the present invention, the locking ball structure includes grooves formed on the side walls of the longitudinal and transverse sliding grooves, an elastic element is provided in the groove, and a ball is connected to the end of the elastic element, the ball being fitted into the groove.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This invention improves upon traditional stepless adjustment by incorporating two sets of locking bead structures on the fixed horizontal plate and the movable vertical plate, transforming it into a stepped adjustment mechanism. This allows operators to quickly lock the target specification (e.g., five rows and five columns, six rows and six columns) by simply pushing and pulling the movable vertical plate and the telescopic push plate once, through precise engagement of the locking beads with preset positions. This achieves efficient and rapid switching, improving production efficiency. Furthermore, by incorporating a two-stage propulsion structure on both the movable vertical plate and the telescopic push plate, the battery pack is further brought inwards to abut against each other after the initial specification switching and locking, eliminating gaps between adjacent cells and improving the overall assembly quality of the battery pack.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, this utility model provides a battery pack assembly device for achieving rapid and precise assembly of individual battery cells, suitable for battery pack production scenarios of various specifications. Figure 1 As shown, the device includes a fixed horizontal plate 1 and a fixed vertical plate 2, which are perpendicularly and fixedly connected to each other, forming the main frame of the equipment. A horizontal sliding groove 3 is formed along the length of the fixed horizontal plate 1, and multiple locking ball structures 4 are arranged in a linear array within the horizontal sliding groove 3. Figure 4As shown, the locking ball structure 4 includes grooves 20 formed on the side walls of the longitudinal sliding groove 6 and the transverse sliding groove 3. An elastic element 21 (e.g., a compression spring) is fixedly installed in the groove 20, and a ball 22 is connected to the end of the elastic element 21. The ball 22 is partially embedded in the groove 20 and can extend and retract radially along the groove 20 under the action of the elastic element 21. A movable longitudinal plate 5 is slidably installed in the transverse sliding groove 3. The movable longitudinal plate 5 is parallel to the fixed longitudinal plate 2 and has a mating groove that matches and engages with the locking ball structure 4. The shape of the mating groove matches the ball 22 in the locking ball structure 4. When the movable longitudinal plate 5 slides along the transverse sliding groove 3 to a designated position, the ball 22 is embedded in the mating groove under the elastic force of the elastic element 21, realizing the snap-fit ​​positioning of the movable longitudinal plate 5. By applying external force, the ball 22 can disengage from the mating groove, allowing the movable longitudinal plate 5 to continue sliding to adjust the distance between it and the fixed longitudinal plate 2 to adapt to the assembly requirements of battery packs of different widths.

[0028] like Figure 1 As shown, longitudinal grooves 6 are respectively formed on the opposing surfaces of the movable longitudinal plate 5 and the fixed longitudinal plate 2. Locking ball structures 4, identical to those in the transverse groove 3, are arranged in a linear array within the longitudinal grooves 6. A connecting rod 7 is provided within the longitudinal groove 6, sliding along the length of the groove and being limited in its connection to the groove, allowing it to move synchronously with the movable longitudinal plate. This limited connection can be achieved through a slot and a slider. A connecting groove is formed on the connecting rod 7, which matches and engages with the ball bearing 22 within the longitudinal groove 6. The connecting rod 7 achieves limited sliding through the engagement of the connecting groove with the locking ball structure 4, ensuring stable movement within the longitudinal groove 6. Furthermore, the connecting rod 7 is fixedly connected to a telescopic push plate 8 (the telescopic push plate 8 can use existing interlocking telescopic plates to change its length as the movable longitudinal plate 5 moves). The telescopic push plate 8 is arranged parallel to the fixed transverse plate 1. The fixed horizontal plate 1, fixed vertical plate 2, movable vertical plate 5, and telescopic push plate 8 together form the assembly area 9, which is used to accommodate the battery cells to be assembled. The telescopic push plate 8 moves by sliding the connecting rod 7 within the longitudinal sliding groove 6, thus adjusting the length of the assembly area 9.

[0029] In this device, two sets of locking bead structures 4 determine the specifications of different battery packs. Different locking bead structures 4 in the longitudinal sliding groove 6 and the transverse sliding groove 3 cooperate with each other to form assembly areas 9 with different widths and lengths. The size of this assembly area 9 is a preset size that conforms to the specifications of different battery packs, thus forming a battery pack specification that can be quickly assembled according to different needs (e.g., three rows and three columns, five rows and five columns).

[0030] When assembling the battery pack, first select the battery pack specifications to be assembled, such as four rows and four columns or five rows. Then slide the movable vertical plate 5 and the telescopic push plate 8 onto the corresponding locking ball structure 4 to engage, forming the corresponding splicing area specifications.

[0031] To facilitate the sliding of the telescopic push plate 8 and avoid inconvenience and reduced stability caused by direct contact with the telescopic push plate 8 during sliding, mounting plates 10 are further fixedly provided at the ends of the movable longitudinal plate 5 and the fixed longitudinal plate 2 away from the fixed transverse plate 1. Figure 1 As shown, a through hole 11 is provided on the mounting plate 10, and a slide rod 12 is axially slidably disposed within the through hole 11. The body of the slide rod 12 is fixedly connected to the connecting rod 7, and the end of the slide rod 12 is fixedly connected to the telescopic push plate 8. Thus, when the telescopic push plate 8 is moved, the slide rod 12 can be grasped from the outside for movement.

[0032] Because there are gaps between the battery cells placed in assembly area 9, in order to eliminate these gaps and improve the accuracy and production quality of subsequent welding, auxiliary component bonding, etc., Figure 2 As shown, the slide rod 12 in this device includes an outer sleeve rod 13, a fixing ring 14, and an inner push rod 15. The outer sleeve rod 13 is a hollow cylindrical structure, axially sliding within the through hole 11, and the connecting rod 7 is fixed to the outer wall of the outer sleeve rod 13 by welding. The fixing ring 14 is coaxially fixed to the inner wall of the outer sleeve rod 13, and the inner push rod 15 is coaxially connected to the fixing ring 14 by threads. The end of the inner push rod 15 is fixedly connected to the telescopic push plate 8 by bolts.

[0033] Once the telescopic push plate 8 is pushed into position by the slide rod 12, the inner push rod 15 is rotated to feed it threadedly relative to the fixed ring plate 14, thereby achieving fine adjustment of the telescopic push plate 8 and pushing the battery pack together in the length direction to eliminate the gap between adjacent battery packs.

[0034] like Figure 1 and Figure 3 As shown, similarly, a linear groove 16 is provided on the side of the movable longitudinal plate 5 facing the assembly area 9, and a transverse push plate 17 is embedded in the linear groove 16. The transverse push plate 17 is located below the longitudinal sliding groove 6, and a stud 18 is rotatably mounted on it. The stud 18 is connected to the middle of the movable longitudinal plate 5 by threaded engagement. When the stud 18 rotates around its own axis, the threaded connection creates a feed, thereby pushing the battery pack from the width direction of the assembled battery pack and eliminating the gaps between the battery cells.

[0035] In addition, such as Figure 3 As shown, in order to avoid interference between the transverse push plate 17 and the telescopic push plate 8 during the movement, the distance between the end of the telescopic push plate 8 and the movable longitudinal plate 5 is controlled, so that there is a clearance gap 19 between the end of the telescopic push plate 8 and the surface of the movable longitudinal plate 5, and the distance of the screw 18 fed by the thread is controlled, so that the screw 18 pushes the transverse push plate 17 to move along the linear groove 16 within the clearance gap 19 by rotation.

[0036] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
