Description

Technical Field

[0001] The present invention generally relates to the technical field of lithium batteries, and more specifically, to a battery module clamp. Background Art

[0002] The lithium battery assembly process involves systematically assembling, connecting, and protecting individual lithium battery cells (such as cylindrical, prismatic, and pouch cells) into battery packs (or modules) with specific voltage, capacity, and functionality. This process meets the high voltage and capacity requirements of end devices (such as electric vehicles, energy storage systems, and consumer electronics). Its core goal is to ensure the consistency, safety, reliability, and performance stability of the battery pack.

[0003] After the battery modules are assembled, glue-coated side panels need to be installed on the sides and secured to the battery modules. The existing method for securing the side panels is to use a C-shaped clamp. This clamp is moved above the battery modules and adjusted to clamp the modules tightly, thereby securing the side panels to the sides and achieving a preliminary cure of the glue on the side panels. However, the C-shaped clamp has to be moved back and forth above the battery modules, which is inconvenient and prone to safety accidents. The slow movement of the C-shaped clamp also affects the efficiency of the side panel installation.

[0004] In view of this, there is an urgent need to provide a battery module clamp to solve the problem. Utility Model Content

DETAILED DESCRIPTION

[0024] The embodiments will now be described with reference to the accompanying drawings. It should be understood that for simplicity and clarity of explanation, reference numerals may be repeated in the accompanying drawings to indicate corresponding or similar elements, where deemed appropriate. In addition, the present invention sets forth many specific details in order to provide a thorough understanding of the embodiments described herein. However, one of ordinary skill in the art will understand that the embodiments described herein may be practiced without these specific details. In other cases, well-known methods, processes, and components are not described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be construed as limiting the scope of the embodiments described herein.

[0025] like Figures 1 to 3 As shown, according to one embodiment of the present invention, a battery module clamp is provided, including: a base plate 11, a vertical plate 12 is vertically arranged above the base plate 11, and a pressure plate 13 is respectively provided on both sides of the vertical plate 12, and the area between each pressure plate 13 and the vertical plate 12 is used to place the battery module 10; when the pressure plate 13 squeezes one side of the battery module 10, the other side of the battery module 10 opposite to the one side rests on the vertical plate 12; and also includes a plurality of pressure strips 14, each of the pressure strips 14 is used to press the poles of each battery cell of the battery module 10 so that the height of each battery cell remains consistent.

[0026] In the above embodiment, the linear motion of the pressing plate 13 toward the vertical plate 12 to compress the battery modules can be achieved by controlling the linear motion using the following structure. Specifically, linear guides 21 are symmetrically arranged on the upper surface of the base plate 11, and sliders are symmetrically arranged on the bottom of the pressing plate 13. The sliders are configured to slide along the linear guides 21 to move the pressing plate 13 toward or away from the vertical plate 12. Two or four linear guides 21 can be provided, and the number of corresponding sliders should also be at least two, four, or more.

[0027] The drive structure by which the pressure plate 13 moves can be a screw drive. Specifically, it can include a screw 31 and a screw nut for driving the movement of the pressure plate 13. A screw support seat 32 is fixedly provided on the pressure plate 13. The first end of the screw 31 is fixedly connected to the screw support seat 32. The screw nut is provided on a mounting seat 33. The mounting seat 33 is fixedly connected to the base plate 11. The second end of the screw 31 is used to connect to the drive device. The screw support seat 32 here is equipped with a pair of angular contact ball bearings, which can cause the screw support seat 32 to move along the axial direction of the screw 31 when the screw 31 rotates.

[0028] To drive the screw rod 31 to rotate from the second end thereof, an electric wrench may be used. For example, when the cross section of the second end of the screw rod 31 is a regular hexagon, an inner hexagon socket may be used to drive the screw rod 31 to rotate.

[0029] In one embodiment, the holding strips 14 can be secured by latches 51 to prevent any cell in the battery module from moving upward due to the force exerted by the pressing plate 13 when squeezing the sides of the battery module. Specifically, each holding strip 14 is secured to a latch 51 at each end, and includes two symmetrically arranged support brackets for securing the latches 51.

[0030] In the above embodiment, each support frame includes a vertical rod 61 and a horizontal rod 62. The vertical rod 61 is fixedly arranged on the base plate 11, and the horizontal rod 62 is fixedly connected to the vertical rod 61. Each lock buckle 51 is symmetrically arranged on the horizontal rod 62.

[0031] In the above embodiment, the structure of the lock buckle 51 may include a lock seat and a barb, the bottom of the barb is hinged to the lock seat, and the top of the barb has an inclined surface for allowing the pressure strip 14 to slide along the inclined surface into the inner side of the barb.

[0032] It is easy to understand that the two hooks of the two locking buckles 51 for engaging the two ends of a bead 14 have inclined surfaces arranged opposite to each other, so that when the two ends of a bead 14 respectively contact the two oppositely arranged inclined surfaces, they can slide along the inclined surfaces into the inner side of the hooks and be locked. When unlocking is required, the barbs are moved to separate the two ends of the bead 14 from the inner side of the barbs, and the bead 14 can be removed to unlock.

[0033] In some embodiments, support bars 81 for supporting the battery module may be further provided on the upper surface of the base plate 11. The purpose of providing the support bars 81 on the upper surface of the base plate 11 is to enable the battery module to avoid the linear guide rail 21 when being placed. Obviously, the linear guide rail 21 can pass under the support bars 81, that is, the upper surface of the support bars 81 is higher than the linear guide rail 21.

[0034] In the above embodiment, the support bar 81 is made of sintered steel, which has the advantages of being waterproof, corrosion-resistant, and having good support. During the extrusion of the battery module, it not only plays an insulating role but also plays a good supporting role.

[0035] In other embodiments, a non-metallic cushioning layer is provided on the inner surface of the pressure plate 13 and on both sides of the vertical plate 12. The cushioning layer may be made of polyurethane. The purpose of providing the non-metallic cushioning layer is to prevent the metal pressure plate 13 and vertical plate 12 from directly contacting the sides of the battery module, thereby providing insulation.
