Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, specifically to a bidirectional pressure restraint tray. Background Technology

[0002] With the booming development of new energy vehicles and the increasing demands on their range, safety, and charging speed, the requirements for batteries are also rising. During the battery formation process, a large amount of gas is generated. If this gas is not released in time, it can easily cause the battery casing to expand, affecting the battery's appearance and performance. To limit this expansion, a restraint tray is typically used to confine the battery.

[0003] For example, Chinese utility model patent with authorization publication number CN218957801U discloses a portable restraint tray for lithium batteries, including a restraint tray shell, several battery separators, and several battery separators spaced apart inside the restraint tray shell. It also includes a restraint structure, which includes an adjusting restraint plate and an adjusting rod. The adjusting restraint plate is arranged parallel to the battery separators and is located between the battery separators and the end face fixing plate of the restraint tray shell. The adjusting rod passes through the end face fixing plate and the adjusting restraint plate in sequence. The adjusting rod is threadedly connected to the end face fixing plate and rotatably connected to the adjusting restraint plate.

[0004] The aforementioned portable lithium battery restraint tray adjusts the spacing between battery separators by rotating an adjusting rod, thereby achieving the effect of tightening and loosening restraint. When the adjusting rod applies clamping force to the adjusting restraint plate, the force first acts on the battery separator connected to the adjusting restraint plate, and then is transmitted to other battery separators through a linkage mechanism. In this process, there is a certain energy loss with each transmission, which causes the pressure on the rear battery separators to gradually decrease, and the battery separators located at one end of the adjusting restraint plate cannot provide sufficient clamping force.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] This embodiment provides a bidirectional pressure restraint tray, such as... Figures 1 to 11 As shown, the device includes a base frame 1, which contains two sets of restraint mechanisms 11. Each set of restraint mechanisms 11 includes multiple sets of restraint components 110. Each set of restraint components 110 includes a first liner 112 and a second liner 113. A restraint space for restraining the battery is formed between the first liner 112 and the second liner 113.

[0042] A first support platform 1122 extends from the bottom of the inner side of the first liner 112, and a second support platform 1132 extends from the bottom of the inner side of the second liner 113. When the battery is placed in the restraint space, the first support platform 1122 and the second support platform 1132 can support the battery and prevent the battery from falling out of the restraint space.

[0043] A first guide platform 1123 is provided on the inner side of the first liner 112, and a second guide platform 1133 is provided on the inner side of the second liner 113. The first guide platform 1123 and the second guide platform 1133 are joined together to form a guide groove. When the battery is placed into the restraint space, the first guide platform 1123 and the second guide platform 1133 can play a certain guiding role, making it easier for the battery to be placed smoothly into the restraint space. It should be noted that setting two sets of restraint mechanisms 11 in the base frame 1 is the optimal choice for this embodiment. In actual use, multiple sets of restraint mechanisms 11 can be set in the base frame 1.

[0044] Furthermore, the restraint mechanism 11 also includes push plate assemblies 2 disposed at both ends of the restraint assembly 110. The push plate assembly 2 includes a first push plate 21 and a second push plate 22 arranged in parallel. The first push plate 21 and the second push plate 22 are respectively arranged along the direction of the arrangement of multiple sets of restraint assemblies 110, and the second push plate 22 is located between the two first push plates 21. The two first push plates 21 are engaged with the first liner 112, and the second push plate 22 is engaged with the second liner 113.

[0045] The first liner 112 has a first protrusion 1121 at its end connected to the first push plate 21, and a first groove 211 on the inner side of the first push plate 21, with the first protrusion 1121 engaging within the first groove 211. The second liner 113 has a second protrusion 1131 at its end connected to the second push plate 22, and a second groove 221 on the inner side of the second push plate 22, with the second protrusion 1131 engaging within the second groove 221. In use, by driving the pair of first push plates 21 to the right and simultaneously driving the second push plate 22 to the left, the first liner 112 and the second liner 113 can be brought closer together to achieve restraint; conversely, they can be moved apart to achieve release.

[0046] Furthermore, a stabilizing plate 3 is provided on the pusher assembly 2, and multiple stabilizing plates 3 are arranged perpendicularly to the pusher assembly 2. Each of the multiple stabilizing plates 3 has a slot 31 on its inner side, which slidably engages with the first pusher plate 21 and the second pusher plate 22. An upper pressure plate 4 is also provided on the top of the stabilizing plates 3, fixedly mounted on the top of the multiple stabilizing plates 3 and perpendicular to them. Since the stabilizing plates 3 are slidably engaged with the first pusher plate 21 and the second pusher plate 22 through the slots 31, the slots 31 have a guiding function when the first pusher plate 21 and the second pusher plate 22 move, ensuring that the first pusher plate 21 and the second pusher plate 22 maintain linear movement during movement and preventing tilting or misalignment. The upper pressure plate 4, fixedly mounted on the top of the stabilizing plates 3, can fix the stabilizing plates 3 and maintain the stability of the overall structure.

[0047] Furthermore, the restraint mechanism 11 also includes a restraint and pressure mechanism 5, which includes a first connecting block 51 and a second connecting block 52 arranged parallel to each other and vertically, as well as a first link assembly 53 and a second link assembly 54. The first link assembly 53 includes a left upper connecting rod 531 and a right upper connecting rod 532 symmetrically arranged. One end of the left upper connecting rod 531 is hinged to the left side of the first connecting block 51, and one end of the right upper connecting rod 532 is hinged to the right side of the first connecting block 51. The second link assembly 54 includes a left lower connecting rod 541 and a right lower connecting rod 542 symmetrically arranged. One end of the left lower connecting rod 541 is hinged to the left side of the second connecting block 52, and one end of the right lower connecting rod 542 is hinged to the right side of the second connecting block 52.

[0048] A first connecting plate 55 is provided on the right side of the first connecting block 51 and the second connecting block 52. The first connecting plate 55 connects two first push plates 21. The other ends of the upper connecting rod 532 and the lower connecting rod 542 on the right side are respectively hinged to the first connecting block 51. A second connecting plate 56 is provided on the left side of the first connecting block 51 and the second connecting block 52. The second connecting plate 56 connects to the second push plate 22. The other ends of the upper connecting rod 531 and the lower connecting rod 541 on the left side are respectively hinged to the second connecting plate 56.

[0049] The restraint and pressure mechanism 5 also includes a bidirectional power device for driving the first connecting block 51 and the second connecting block 52 to move closer and further apart. The bidirectional power device is a bidirectional lead screw 57, which is threaded to the first connecting block 51 and the second connecting block 52 and passes through the first connecting block 51 and the second connecting block 52 in sequence.

[0050] In use, when restraint is required, an external power source drives the bidirectional lead screw 57 to rotate, causing the first connecting block 51 and the second connecting block 52 to move closer together. At this time, the first connecting plate 55 moves to the right under the influence of the upper connecting rod 532 on the right and the lower connecting rod 542 on the right, and the second connecting plate 56 moves to the left under the influence of the upper connecting rod 531 on the left and the lower connecting rod 541 on the left. Since the first connecting plate 55 is connected to the first push plate 21 and the second connecting plate 56 is connected to the second push plate 22, when the first connecting plate 55 moves to the right, it can simultaneously drive the first push plate 21 to move to the right, and when the second connecting plate 56 moves to the left, it can simultaneously drive the second push plate 22 to move to the left. The first push plate 21 is engaged with the first liner 112, and the second push plate 22 is engaged with the second liner 113. When the first push plate 21 moves to the right, it can simultaneously drive the first liner 112 to move to the right. When the second liner 113 moves to the left, it can simultaneously drive the second liner 113 to move to the left, so that the first liner 112 and the second liner 113 move closer to each other, thereby achieving the restraint action on the battery.

[0051] When it is necessary to release the restraint, the bidirectional lead screw 57 is rotated in the reverse direction by an external power source, causing the first connecting block 51 and the second connecting block 52 to move away from each other. At this time, the first connecting plate 55 moves to the left under the action of the upper connecting rod 532 on the right and the lower connecting rod 542 on the right, and the second connecting plate 56 moves to the right under the action of the upper connecting rod 531 on the left and the lower connecting rod 541 on the left. This causes the first push plate 21 to move to the left and the second push plate 22 to move to the right, which in turn causes the first liner 112 to move to the right and the second liner 113 to move to the left, causing the first liner 112 and the second liner 113 to move away from each other, thus realizing the release action of the battery.

[0052] Furthermore, the top of the bidirectional lead screw 57 extends through the upper pressure plate 4, and a mounting hole 41 is provided on the upper pressure plate 4 for the bidirectional lead screw 57 to pass through. By providing the mounting hole 41, it is convenient to connect the bidirectional lead screw 57 to an external power source, and when the external power source drives the bidirectional lead screw 57 to rotate, the mounting hole 41 can ensure that the bidirectional lead screw 57 will not deviate during the rotation.

[0053] In the description of this utility model, it is obvious that the described embodiments are only a part of the embodiments of this utility model, and not all of them. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
