Description

Technical Field

[0001] This utility model relates to the field of battery pack energy storage equipment technology, and in particular to portable lithium battery pack energy storage equipment for automotive power batteries. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material 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 controls. Therefore, lithium-ion batteries were not widely used for a long time. With the development of science and technology, lithium-ion batteries have now become mainstream. However, in existing lithium-ion batteries, when multiple batteries are connected together, the connecting devices are exposed on the outside, which can easily damage the battery. Furthermore, existing lithium-ion batteries are inconvenient for users to carry.

[0003] An existing portable lithium battery pack energy storage device for automotive power batteries (publication number: CN208489251U) has at least the following drawbacks: This device facilitates the connection of two energy storage devices by using a connecting block and a fixing plate. A second spring inside the movable plate allows it to rotate automatically clockwise, simultaneously closing the first sliding groove and protecting the connector. Pulling up the pull strap causes the second slider to slide upwards, stretching the first spring. When the user releases the pull strap, the first spring moves the second slider downwards, ensuring the pull strap is firmly against the cover surface, thus preventing the pull strap from being carelessly placed and causing danger. However, this invention cannot install and fix batteries of different models, and battery replacement is not convenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable lithium battery pack energy storage device for automotive power batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable lithium battery pack energy storage device for automotive power batteries includes two symmetrically mounted mounting housings. Each of the two mounting housings has several hinged posts equidistantly arranged on its left and right inner walls. Each hinged post is hinged with a connecting rod. The ends of the connecting rods furthest from the hinged posts are connected to a mounting bracket. Several batteries are placed equidistantly on the mounting bracket. Several mounting plates are equidistantly arranged on the inner walls of the two mounting housings on both sides of the batteries. Each mounting plate is fixedly mounted with a spring, and the ends of the springs furthest from the mounting plates are fitted with fixing claws. A sliding mounting plate is installed between the top surfaces of the two mounting housings, and several springs are equidistantly mounted on the bottom surface of the sliding mounting plate.

[0007] As a further embodiment of this utility model, the left and right side walls of the two mounting housings are respectively provided with buckles and spring pins, and the size of the buckles is adapted to the size of the spring pins.

[0008] As a further embodiment of this utility model, handles are installed on the top surfaces of both mounting housings, and casters are installed at the four corners of the bottom surfaces of both mounting housings.

[0009] As a further embodiment of this utility model, the mounting bracket has an integrally formed mounting arm at both ends, and several protruding posts are provided at equal intervals on the two mounting arms. The ends of several connecting rods away from the hinge posts are respectively hinged to the several protruding posts.

[0010] As a further embodiment of this utility model, several trays are equidistantly mounted on the horizontal plate of the mounting bracket, and several batteries are respectively mounted on the trays.

[0011] As a further embodiment of this utility model, two mounting grooves are provided on the inner top surfaces of the two mounting housings, and two sets of sliding rods are symmetrically provided on the front and rear walls of the sliding mounting plate, with the two sets of sliding rods being slidably inserted into the mounting grooves respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This device connects the mounting bracket to two mounting housings via several connecting rods. The opening and closing of the two mounting housings causes the mounting bracket and several batteries to rise or fall. Several fixing claws equipped with springs (first type) limit the horizontal position of the batteries, while springs (second type) mounted on the bottom surface of the tray and sliding mounting plate limit the vertical position of the batteries. The opening and closing of the two mounting housings is controlled by the cooperation of buckles and spring pins. This device can install and fix batteries of different models, and the battery pack can be replaced quickly and conveniently, improving work efficiency. Moreover, the compact structural design facilitates the installation, disassembly, and replacement of parts. Attached Figure Description

Several mounting plates 12 are equidistantly arranged on both sides of the batteries 4 on the inner walls of the two mounting housings 1. Each mounting plate 12 is fixedly mounted with a spring 5. Each spring 5 is mounted with a fixing claw 51 at its end away from the mounting plate 12. A sliding mounting plate 6 is installed between the top surfaces of the two mounting housings 1. Several springs 7 are equidistantly installed on the bottom surface of the sliding mounting plate 6.

[0024] In this embodiment, the left and right side walls of the two mounting housings 1 are respectively provided with buckles 14 and spring pins 15, and the size of the buckles 14 is adapted to the size of the spring pins 15.

[0025] In this embodiment, a handle 16 is installed on the top surface of both mounting housings 1, and casters 8 are installed at the four corners of the bottom surface of both mounting housings 1.

[0026] In this embodiment, the mounting bracket 3 has an integrally formed mounting arm 31 at both the left and right ends. Several protrusions 311 are provided on the two mounting arms 31 at equal intervals.
