Abstract

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream. They can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Currently, lithium-ion batteries are widely used in various fields.
[0003] Currently, most lithium battery packs are equipped with an outer protective shell, which, along with the cover, forms an integrated lithium battery protection device. However, some of these covers and outer protective shells are not suitable for lithium battery packs of different sizes, resulting in low applicability. In addition, lithium batteries generate heat during use, and if this heat cannot be dissipated to the outside, it will affect the normal operation of the lithium battery. Utility Model Content

[0018] 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.
[0019] Please see Figure 1-4 As shown, a lithium battery cover structure includes a housing 1 and a cover 2 movably disposed on the surface of the housing 1. The surface of the housing 1 is provided with a plurality of bolts 3 that are connected to the cover 2. The surface of the cover 2 is provided with a charging port 4 that is connected to the lithium battery. The charging port 4 is a 2+6 charging port 4. The surface of the cover 2 is provided with an Anderson plug 5. A support platform 6 is fixed in the inner cavity of the housing 1. An adjustment mechanism 7 is provided in the inner cavity of the support platform 6. A clamping plate 9 for clamping the lithium battery is provided on the surface of the adjustment mechanism 7. A heat dissipation mechanism 10 is provided on the surface of the clamping plate 9.
[0020] When in use, the lithium battery located in the outer casing 1 can connect with the outside world through the charging port 4 and the Anderson plug 5, improving the practicality of the device. In addition, under the action of the adjustment mechanism 7 and the clamping plate 9, lithium battery blocks of different sizes can be clamped, thereby improving the applicability of the device. Furthermore, when the lithium battery is in use, the heat dissipation mechanism 10 can improve the heat dissipation capacity of the device for the lithium battery, thereby improving the stability of the lithium battery during operation and further enhancing the practicality of the device.
[0021] The adjusting mechanism 7 includes a worm 71 that rotates within the cavity of the support platform 6. A worm wheel 72 meshes with the surface of the worm 71. A transmission rod 73 is fixed within the cavity of the worm wheel 72. Both sides of the surface of the transmission rod 73 are provided with bidirectional threaded rods 74 via bevel gear transmission. Both sides of the surface of the bidirectional threaded rod 74 are meshed with engagement blocks 75. A hinge plate 76 is hinged to the surface of the engagement blocks 75. The other end of the hinge plate 76 is hinged to the clamping plate 9. In this embodiment, through the arrangement of the worm 71, worm wheel 72, transmission rod 73, bidirectional threaded rod 74, engagement blocks 75, and hinge plate 76, when the worm 71 rotates, the worm wheel 72 meshing with the surface of the worm 71 can cause the transmission rod 73 to rotate. Consequently, the bidirectional threaded rods 74, which are driven by bevel gear transmission at both ends of the transmission rod 73, can rotate. Under the action of the bidirectional threaded rods 74, the engagement blocks 75 drive the hinge plate 76 to move, thereby causing the hinge plate 76 to drive the clamping plate 9 to work.
[0022] The two bidirectional threaded rods 74 on both sides have the same specifications and their thread directions are mutually matched. In this embodiment, this arrangement makes the movement directions of several meshing blocks 75 mutually matched when the two bidirectional threaded rods 74 on both sides rotate, thereby improving the coordination of the device.
[0023] A rotating head 8 is fixed to one end of the worm 71. The thread helix angle of the bidirectional threaded rod 74 is less than the equivalent friction angle. In this embodiment, the rotating head 8 facilitates the operation of the worm 71 by the operator. With the thread of the bidirectional threaded rod 74, the meshing block 75 can be stably stopped at the designated position.
[0024] The heat dissipation mechanism 10 includes several bonding tubes 101 fixed to the surface of the clamping plate 9. A slide rod 102 is slidably disposed on the surface of the bonding tube 101. The slide rod 102 is disposed through the inner wall of the outer shell 1. A heat sink 103 is fixed to the other end of the slide rod 102. Both the bonding tube 101 and the slide rod 102 are made of heat dissipation metal. In this embodiment, through the arrangement of the bonding tube 101, the slide rod 102 and the heat sink 103, the temperature of the lithium battery can be conducted to the surface of the clamping plate 9. Then, the bonding tube 101 on the surface of the clamping plate 9 can conduct the temperature to the slide rod 102 and the heat sink 103. Thus, under the action of the heat sink 103, the purpose of heat dissipation is achieved.
[0025] Bearing seats 11 are rotatably provided on both sides of the surface of the bidirectional threaded rod 74. The other end of the bearing seat 11 is fixed to the inner cavity of the outer shell 1. In this embodiment, the bearing seats 11 provide a limit for the rotation of the bidirectional threaded rod 74, thereby improving the stability of the bidirectional threaded rod 74 during rotation.
[0026] Working principle: When using this device, the operator can use bolt 3 to separate the outer shell 1 and the cover plate 2, and then place the lithium battery on the surface of the support platform 6 in the outer shell 1. The operator can then use the rotating head 8, which causes the worm gear 71 to rotate. The worm wheel 72 meshing with the surface of the worm gear 71 causes the transmission rod 73 to rotate. Then, under the action of the bidirectional threaded rod 74 and the meshing block 75, the hinge plate 76 drives the clamping plate 9 to move. Thus, under the action of the clamping plates 9 on both sides, the lithium battery can be clamped, making the lithium battery more stable in the outer shell 1. After that, the operator connects the lithium battery to the charging port 4 and the Anderson plug 5. During daily use of the lithium battery, the heat generated by the lithium battery can be conducted through the clamping plate 9 to the bonding tube 101 and the slide rod 102, and then the heat is dissipated to the outside by the heat sink 103, improving the stability of the lithium battery during use.
