Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a mobile device using a pouch lithium battery. Background Technology

[0002] Currently, lithium batteries are widely used and require a large production volume. Before being manufactured, lithium batteries need to be tested for voltage, current, resistance, and packaging to ensure that the batteries flowing out meet the specifications.

[0003] However, in the existing technology, when lithium battery packaging and transportation proceed to the next step, such as labeling or installation, they are usually placed in boxes, with multiple lithium battery packs stacked inside the boxes. However, during transportation, the shaking can easily cause collisions, resulting in damage to the lithium battery packs. Therefore, a solution is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, when lithium battery packaging and transportation proceeds to the next step, such as labeling or installation, they are usually placed in boxes with multiple lithium battery packs stacked inside. However, during transportation, the packs are prone to collisions due to shaking, leading to damage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mobile device for soft-pack lithium batteries, comprising: a drying and transfer box and a door; two sliding grooves formed on the inner wall of the drying and transfer box at symmetrical locations; and further comprising:

[0006] Multiple mounting bases are fixedly installed at the four corners of one side surface of the drying transfer box. Dampers are fixedly installed on the inner walls of the multiple mounting bases. Mounting plates are installed at the output ends of the multiple dampers. The multiple mounting plates are connected to the surface of the drying transfer box by spring one. Rollers are installed on one side surface of the multiple mounting plates. Spring two is fixedly installed on the surface of the drying transfer box at a symmetrical location.

[0007] Two long rods are fixedly installed symmetrically on one side surface of the box door. Positioning holes are opened on one side surface of the two long rods, and the two long rods are slidably embedded in the inside of the slide groove.

[0008] Preferably, one end of each of the two springs is provided with a positioning pin, and one end of each positioning pin is movably embedded inside the positioning hole.

[0009] The technical effect of adopting the above-mentioned further solution is that the spring provides a reset function for the two pairs of positioning pins, which facilitates the positioning pins to be embedded in the positioning holes for positioning.

[0010] Preferably, a limiting groove is formed on one side surface of the door, and a bidirectional lead screw is provided in the bearing inside the limiting groove.

[0011] The technical effect of adopting the above-mentioned further solution is that the bidirectional lead screw is limited by the limiting groove on the surface of the box door.

[0012] Preferably, a worm gear is fixedly provided on one end surface of the bidirectional lead screw, and a movable frame is threadedly fitted on the surface of the bidirectional lead screw at a symmetrical location.

[0013] The technical effect of adopting the above-mentioned further solution is that when the bidirectional lead screw rotates, the worm gear rotates, and at the same time, the moving frame on the outer surface moves along the inside of the limiting groove for centering.

[0014] Preferably, multiple protective pads are provided on the surfaces of the two movable frames facing each other, and a mounting bracket is fixedly provided on the inner wall of the box door.

[0015] The technical effect of adopting the above-mentioned further solution is that the protective pad on the surface of the mobile frame contacts the soft-pack lithium battery, providing protection.

[0016] Preferably, a worm gear is movably disposed inside the mounting bracket, and the worm gear meshes with a worm wheel.

[0017] The technical effect of adopting the above-mentioned further solution is that when the worm gear inside the rotating mounting bracket is rotated, it drives the meshing worm wheel to rotate, which in turn drives the bidirectional lead screw and provides self-locking operation.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by placing the soft-pack lithium battery on the surface of the movable frame and making it contact with the protective pad, the worm gear inside the rotating mounting frame drives the worm wheel to perform transmission work, so that the movable frame on the outer surface of the bidirectional screw moves along the inner limit groove to fix the soft-pack lithium batteries of different sizes, thereby preventing the soft-pack lithium batteries from being damaged by collision during movement.

[0020] 2. In this utility model, a long rod on the surface of the box door is embedded along the inside of the sliding groove. When the long rod contacts the inclined surface of the positioning pin, the positioning pin is displaced on the surface of the drying transfer box by means of spring two, thus completing the protection of the soft-pack lithium battery. In addition, when it needs to be moved, it is moved by the rollers on the surface of the mounting plate. The two ends of the damper and spring one are respectively connected to the surface of the drying transfer box and spring one. However, when encountering bumps or other problems during the movement, buffering and shock absorption work is performed to reduce the impact of bumps on the soft-pack lithium battery, thereby providing more complete protection performance.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, such as Figure 1-4As shown, this utility model provides a mobile device for a soft-pack lithium battery, including: a drying and transfer box 1 and a box door 2; two sliding grooves 101, which are formed on the inner wall of the drying and transfer box 1 at symmetrical locations; and multiple mounting seats 102, which are fixedly set at the four corners of one side surface of the drying and transfer box 1. The inner wall of the multiple mounting seats 102 is fixedly provided with dampers 1021, and the output ends of the multiple dampers 1021 are provided with mounting plates 1022. The multiple mounting plates 1022 are connected to the surface of the drying and transfer box 1 by spring 1023. Rollers 1024 are provided on one side surface of the multiple mounting plates 1022, and spring 203 is fixedly set on the surface of the drying and transfer box 1 at symmetrical locations; and two long rods 201, which are fixedly set at symmetrical locations on one side surface of the box door 2. The two long rods 201 are provided with positioning holes 2011 on one side surface of the two long rods 201, and the two long rods 201 are slidably embedded in the sliding grooves 101.

[0030] In this embodiment, by placing the soft-pack lithium battery on the surface of the movable frame 2022 and making it contact with the protective pad 2023, the worm gear 2031 inside the rotating mounting frame 203 drives the worm wheel 2024 to perform transmission work, so that the movable frame 2022 on the outer surface of the bidirectional lead screw 2021 moves along the inside of the limiting groove 202 to fix soft-pack lithium batteries of different sizes, preventing problems such as collision and damage to the soft-pack lithium batteries during movement.

[0031] In Example 2, one end of each of the two springs 103 is provided with a positioning pin 1031, and one end of each positioning pin 1031 is movably embedded in the positioning hole 2011. A limit groove 202 is provided on one side surface of the door 2, and a double-acting screw 2021 is provided inside the bearing of the limit groove 202. A worm gear 2024 is fixedly provided on one end surface of the double-acting screw 2021. A movable frame 2022 is threaded on the symmetrical surface of the double-acting screw 2021. Multiple protective pads 2023 are provided on the surfaces of the two movable frames 2022 opposite to each other. A mounting frame 203 is fixedly provided on the inner wall of the door 2, and a worm gear 2031 is movably provided inside the mounting frame 203. The worm gear 2031 meshes with the worm gear 2024.

[0032] In this embodiment, the long rod 201 on the surface of the door 2 is embedded along the inside of the slide groove 101. When the long rod 201 contacts the inclined surface of the positioning pin 1031, the positioning pin 1031 is displaced on the surface of the drying transfer box 1 by means of the second spring 103, thus completing the protection of the soft-pack lithium battery. In addition, when it is necessary to move, it is moved by the roller 1024 on the surface of the mounting plate 1022. The two ends of the damper 1021 and the first spring 1023 are respectively connected to the surface of the drying transfer box 1 and the surface of the first spring 1023. However, when encountering bumps or other problems during the movement, buffering and shock absorption work is performed to reduce the impact of bumps on the soft-pack lithium battery, thereby providing more complete protection performance.

[0033] Working principle: In use, the soft-pack lithium battery is placed on the surface of the movable frame 2022 and in contact with the protective pad 2023. By rotating the worm gear 2031 inside the mounting frame 203, the worm wheel 2024 is driven to perform transmission work, causing the movable frame 2022 on the outer surface of the bidirectional lead screw 2021 to move along the inside of the limiting groove 202 for centering. This fixes soft-pack lithium batteries of different sizes and prevents them from being damaged by collisions during movement. In addition, the long rod 201 on the surface of the door 2 is embedded along the inside of the slide groove 101. When the long rod 201 is aligned with the positioning pin 1031... When the inclined surface is in contact, the positioning pin 1031 is displaced on the surface of the drying transfer box 1 by the second spring 103, thus completing the protection of the soft-pack lithium battery. In addition, when it needs to be moved, it is moved by the roller 1024 on the surface of the mounting plate 1022. The two ends of the damper 1021 and the first spring 1023 are respectively connected to the surface of the drying transfer box 1 and the first spring 1023. However, when encountering bumps or other problems during the movement, buffering and shock absorption work is carried out to reduce the impact of bumps on the soft-pack lithium battery, thereby providing more complete protection performance. The whole equipment can be used in conjunction with temperature control system and ventilation system.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
