Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0021] Example 1: Please see Figure 1 - Figure 3 This is the first embodiment of the present utility model. This embodiment provides an adjustable spacing lithium battery pack arrangement and fixing structure, including: a bottom shell 1, an air valve 3, a top shell 5, a fixing plate 8, a connecting rod 9, a fixing seat 10, and a nut 11; the air valve 3 is located at the center of the bottom side of the bottom shell 1, the top shell 5 is located on the top side of the bottom shell 1, the fixing plate 8 is symmetrically fixed at both ends of the top shell 5, the connecting rod 9 is fixed at the bottom side of the fixing plate 8, the fixing seat 10 is fixed at both ends of the bottom shell 1, and the nut 11 is installed at one end of the connecting rod 9, and also includes: Adjustment component 2, fixing component 4, connecting component 6 and limiting component 7; adjustment component 2 is located inside the bottom shell 1, fixing component 4 is located on the top side of adjustment component 2, connecting component 6 is located on both sides of bottom shell 1 and top shell 5, and limiting component 7 is located on the top side of top shell 5.

[0022] Specifically, the adjustment component 2 includes a rectangular groove 21, a movable block 22, an airbag 23, a telescopic cylinder 24, a limiting groove 25, a limiting block 26, and a cavity 27. The rectangular groove 21 is opened inside the bottom shell 1. The movable block 22 is evenly slidably installed inside the bottom shell 1. The cavity 27 is opened inside the movable block 22. The movable block 22 is connected to the airbag 23. The movable block 22 is connected to the telescopic cylinder 24 in a direction perpendicular to the airbag 23. The limiting groove 25 is symmetrically opened at the center of the bottom end of the inner side of the rectangular groove 21. The movable block 22 is slidably installed inside the limiting groove 25 through the limiting block 26. The movable block 22 at the center is fixedly connected to the bottom shell 1. The cavities 27 inside the movable block 22 are interconnected.

[0023] Furthermore, by inflating or deflating the inside of the movable block 22, the airbag 23 and the telescopic cylinder 24 can be extended or shortened, thereby changing the spacing between individual lithium batteries.

[0024] Specifically, the fixing component 4 includes a metal disk 41, a through hole 42, a suction cup 43, and a wire 44. The metal disk 41 is fixed to the top side of the movable block 22. A through hole 42 is provided at the center of the metal disk 41. A suction cup 43 is provided inside the through hole 42 and is fixedly connected to the movable block 22. The metal disk 41 is connected by the wire 44. The suction cup 43 communicates with the inner cavity 27 of the movable block 22.

[0025] Furthermore, by using the metal disk 41 in conjunction with the wire 44, the lithium batteries can be connected in series so that they can be assembled and processed into a battery pack in the future.

[0026] In use, a single lithium-ion battery is placed on the metal disk 41 on the top surface of the moving block 22. The air valve 3 is opened, and with the cooperation of the moving block 22 at the center, the air in the cavity 27 inside each moving block 22 is extracted, causing each moving block 22 to slide inside the rectangular groove 21 until the individual lithium-ion batteries are neatly arranged and in contact. At this time, the pressure inside the cavity 27 decreases, and the suction cup 43 adsorbs and fixes the bottom of the battery to prevent the battery from falling off during assembly. Through this structure, the lithium-ion battery pack can be used to assemble any type of single lithium-ion battery, making it more widely applicable.

[0027] In summary, by adjusting the structure of component 2 and fixing component 4, and by connecting each moving block 22 through the cooperation of airbag 23 and telescopic cylinder 24, the distance between batteries can be adjusted. At the same time, with the cooperation of suction cup 43, the batteries can be neatly arranged and then adsorbed and fixed. The operation is simple and the application range is wider.

[0028] Example 2: Please see Figure 4 - Figure 5 This is the second embodiment of the present utility model.

[0029] Specifically, the connecting component 6 includes a groove 61, a metal plate 62, a cathode connector 63, an anode connector 64, a positioning hole 65, and a screw 66. The groove 61 is opened inside the top shell 5. The metal plate 62 is evenly slidably installed inside the groove 61. One end of the metal plate 62 is connected to the cathode connector 63. The anode connector 64 is fixed to one end of the metal plate 41. Positioning holes 65 are evenly opened on both sides of the bottom shell 1 and the top shell 5. Screws 66 are inserted inside the positioning holes 65.

[0030] Furthermore, the structure of the cathode connector 63 and the anode connector 64 allows the assembled battery pack to be installed inside the equipment, facilitating equipment connection and making operation simple and convenient.

[0031] Specifically, the limiting component 7 includes a top cover 71, a rubber pad 72, and an elastic block 73. The top cover 71 is fastened to the top side of the top shell 5, and the rubber pad 72 is fixed to the bottom side of the top cover 71. The rubber pad 72 is pressed against the surface of the metal plate 62. The elastic blocks 73 are symmetrically fixed at both ends of the top cover 71 and are fastened to both ends of the top shell 5.

[0032] Furthermore, the structure of the rubber pad 72 can limit the position of the assembled battery, preventing its position from shifting and affecting the normal use of the battery pack.

[0033] In use, after the battery pack is assembled, the positive or negative terminals of each lithium-ion battery are connected in series with the help of the wire 44, and the two ends of each battery are connected to the cathode connector 63 and the anode connector 64 respectively. At the same time, the top cover 71 is fastened to the top side of the top shell 5 with the help of the elastic locking block 73, which causes the rubber pad 72 to be pressed against the surface of the metal plate 62 to prevent its position from shifting due to force. At this time, the cathode connector 63 and the anode connector 64 can be slid to the required positioning hole 65 according to the battery model and size. The connector of the device is placed on one side of the cathode connector 63 and the anode connector 64, and the screw 66 is inserted into the device connector and the cathode connector 63 and the anode connector 64. The screw 66 is rotated through the positioning hole 65, thereby realizing the connection between the battery pack and the device for use.

[0034] In summary, by connecting component 6 and limiting component 7, the batteries inside the battery pack are connected in series and then connected to the equipment, thereby providing the equipment with a stable voltage and a large capacity of electrical energy, ensuring the normal operation of the equipment, and making the lithium battery pack easier to use.
