[0028] 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.

[0029] This embodiment provides a bidirectional pressure-applied, fixed-space restraint tray, such as... Figures 1 to 6 As shown, the device includes a tray body 1 and a restraint mechanism 2 disposed within the tray body 1. The restraint mechanism 2 includes multiple sets of restraint components 20. Each set of restraint components 20 includes a first restraint area 21 and a second restraint area 22 arranged in a mirror image. The first restraint area 21 is provided with a first pressure plate 211 and a first pressure receiving plate 212. The second restraint area 22 is provided with a second pressure plate 213 and a second pressure receiving plate 214. Multiple retaining plates 215 are respectively provided between the first pressure plate 211 and the first pressure receiving plate 212 and between the second pressure plate 213 and the second pressure receiving plate 214. A restraint space for restraining the battery is formed between any two adjacent retaining plates 215.

[0030] Further, each card from plate 215 is provided with a bushing from both ends, and each adjacent two card from plates 215 are separated by the bushing 216, and the distance between each bushing 216 can be close or far within a preset range, and the T-shaped table 2163 extends on one side of the bushing 216, and the T-shaped groove 2164 is provided on the other side of the bushing 216, and the adjacent bushings 216 are connected by the sliding connection of the T-shaped table 2163 and the T-shaped groove 2164.

[0031] In the initial state, there is still a certain gap between the T-shaped table 2163 and the T-shaped groove 2164, and by adjusting the gap between the T-shaped table 2163 and the T-shaped groove 2164, the distance between the adjacent card from plates 215 can be adjusted, so that the battery can be placed between the adjacent two card from plates 215.

[0032] When the battery is constrained, the gap between the T-shaped table 2163 and the T-shaped groove 2164 will gradually disappear, and the T-shaped table 2163 and the T-shaped groove 2164 will be tightly fitted, and then the gap between the adjacent card from plates 215 will become smaller, and when a large pressure is applied to the card from plate 215, the bushing 216 can also bear part of the pressure, so that the card from plate 215 will not be deformed due to excessive pressure, and the card from plate 215 can maintain a stable distance through the bushing 216, avoiding damaging the battery in the constrained space.

[0033] When the battery is released, the tight fit between the T-shaped table 2163 and the T-shaped groove 2164 is released, and at this time, the T-shaped table 2163 is still inserted into the T-shaped groove 2164 of the adjacent bushing 216, allowing the adjacent two bushings 216 to move freely within a certain range, while preventing the T-shaped table 2163 and the T-shaped groove 2164 from being completely separated, ensuring that the adjacent bushings 216 are still connected by the T-shaped table 2163 and the T-shaped groove 2164 in the released state, thereby avoiding the battery from falling out of the constrained space.

[0034] It should be noted that in the first constrained area 21, the bushing 216 located at the frontmost position is connected with the first pressing plate 211 and the bushing 216 located at the rearmost position is connected with the first pressure receiving plate 212, therefore, the shape and structure of the bushing 216 located at the frontmost and rearmost positions can be adjusted adaptively, which is different from the shape and structure of the other bushings 216, and the structure of the bushing 216 in the second constrained area 22 is the same.

[0035] Further, the card from plate 215 is connected with the bushing 216, specifically, a first boss 2151 is arranged at the connecting end of the card from plate 215, and a clamping groove 2161 is arranged on the inner side of the bushing 216, and the card from plate 215 and the bushing 216 are connected by the clamping connection of the first boss 2151 and the clamping groove 2161.

[0036] The second protrusions 2152 are used to support the batteries placed in the restraint space, and the third protrusions 2153 are arranged on the side walls of the card from plate 215, and a pair of third protrusions 2153 are arranged at the two ends of the side walls of the card from plate 215 and are perpendicular to the second protrusions 2152, wherein the guide grooves are formed between the adjacent two third protrusions 2153, and the batteries have a certain guiding function when placed in the restraint space.

[0037] Further, the restraint mechanism 2 further comprises a bidirectional power device, which is a bidirectional screw rod 217, used to drive the first pressing plate 211 to move towards the first receiving plate 212, and simultaneously drive the second pressing plate 213 to move towards the second receiving plate 214, so as to press the batteries on both sides of the first restraint area 21 and the second restraint area 22. Compared with unidirectional pressing, bidirectional pressing can reduce cumulative loss and avoid the risk of battery deformation or damage due to excessive force on one side.

[0038] Further, the tray body 1 comprises a chassis 10, and the chassis 10 is provided with a first end plate 11 and a second end plate 12, the first end plate 11 is located at one end of the chassis 10, and the second end plate 12 is located at the other end of the chassis 10. The tray body 1 is further provided with a fixed plate 13, which is located at the middle position in the tray body 1, and the first restraint area 21 and the second restraint area 22 are separated by the fixed plate 13. The bidirectional screw rod 217 penetrates the first pressing plate 211, the fixed plate 13 and the second pressing plate 213, and the two ends of the bidirectional screw rod 217 are connected to the inner sides of the first end plate 11 and the second end plate 12 respectively.

[0039] Further, the pressure sensors 131 are arranged on both sides of the fixed plate 13, the pressure sensor 131 on one side is used to detect the pressure received by the first receiving plate 212, and the pressure sensor 131 on the other side is used to detect the pressure received by the second receiving plate 214. When the bidirectional screw rod 217 drives the first pressing plate 211 to move towards the first receiving plate 212 and simultaneously drives the second pressing plate 213 to move towards the second receiving plate 214, the pressure sensors 131 arranged on both sides of the fixed plate 13 can monitor the pressures received by the first receiving plate 212 and the second receiving plate 214 in real time, which is conducive to ensuring the accurate control of the pressing process.

[0040] Further, the tray body 1 is also provided with a connecting rod assembly 14, which includes a first guide rod 141 and a second guide rod 142. The first guide rod 141 is sequentially and gap-fitted through the first pressing plate 211, the fixed plate 13 and the second pressing plate 213, and is fixedly connected to the inner side of the first end plate 11 and the inner side of the second end plate 12 at both ends. The second guide rod 142 is sequentially and gap-fitted through the first pressing plate 211, the first pressure plate 212, the fixed plate 13, the second pressure plate 214 and the second pressing plate 213, and is fixedly connected to the inner side of the first end plate 11 and the inner side of the second end plate 12 at both ends. A groove 2162 is further provided on the outer side of the bushing 216 and is slidingly connected to the second guide rod 142. By providing the first guide rod 141 and the second guide rod 142, when the bidirectional screw rod 217 drives the first pressing plate 211 and the second pressing plate 213 to be constrained or released, the first pressing plate 211 and the second pressing plate 213 can move smoothly along the predetermined track of the first guide rod 141 and the second guide rod 142, and at the same time, the bushing 216 can move smoothly along the predetermined track of the second guide rod 142, thereby avoiding uneven pressing caused by deviation and battery damage.

[0041] Further, a connecting piece 3 is provided between the first end plate 11 and the first pressing plate 211 and between the second end plate 12 and the second pressing plate 213. The connecting piece 3 includes a first connecting block 30 provided on the inner side of the first end plate 11 and the second end plate 12, and a second connecting block 31 provided on the outer side of the first pressing plate 211 and the second pressing plate 213. The first connecting block 30 is provided with a connecting groove 301, and the second connecting block 31 is provided with a connecting table 311 which can be plugged into the connecting groove 301. When constrained, the first connecting block 30 and the second connecting block 31 are separated from each other, so that the first pressing plate 211 and the second pressing plate 213 can move freely, which facilitates accurate application of pressure by the first pressing plate 211 and the second pressing plate 213. When released, the connecting table 311 on the second connecting block 31 is inserted into the connecting groove 301 on the first connecting block 30. At this time, the first end plate 11 is fixedly connected to the first pressing plate 211 through the connecting piece 3, and the second end plate 12 is fixedly connected to the second pressing plate 213 through the connecting piece 3, thereby avoiding the first pressing plate 211 and the second pressing plate 213 from shaking at will and maintaining the stability of the structure.

[0042] Further, a connecting shaft 111 is further provided on the outer side of the first end plate 11, which is connected to the bidirectional screw rod 217 and used to connect an external power source to drive the bidirectional screw rod 217 to rotate.
