Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement equipment, and specifically to a multifunctional modular lithium battery replacement device. Background Art

[0002] Lithium battery swap cabinet is a device that provides battery replacement services for electric bicycles. Users can scan the code to put the low-power battery into the battery compartment of the cabinet, and then the cabinet will pop out a group of fully charged batteries for users to use, thus shortening the time for users to charge their electric vehicles; the lithium battery swap cabinet is mainly composed of a cabinet body, a battery compartment, lithium batteries and a control module.

[0003] When users use a battery swap cabinet, they will put the depleted battery into the battery compartment. However, the size of the battery compartment is often larger than the size of the battery when it is designed. When the battery is put into the battery compartment, due to the lack of an effective limit or positioning structure, the battery is prone to misplacement, which in turn affects the charging of the battery. In view of this, we propose a multifunctional modular lithium battery swap device. Utility Model Content

A removable back panel 3 is installed at the rear end of the power exchange cabinet 1. The front end face of the back panel 3 is provided with an air intake cavity 30 connected with multiple installation cavities 10. The front end face of the air intake cavity 30 is provided with multiple air intake grooves 32 penetrating the back panel 3. Both side walls of the air intake cavity 30 are provided with multiple fixed grooves 31. A fixing frame 33 is inserted between two adjacent fixed grooves 31. Multiple dust filters 34 are installed at the opening of the fixing frame 33. Springs 35 are fixed at the left and right ends of the front end face of the fixing frame 33, and the front end of the spring 35 is pressed against the rear end face of the power exchange cabinet 1.

[0034] In this embodiment, the front end of the transmission rod 29 passes through the front end surface of the battery compartment 2, and the front end of the transmission rod 29 is coaxially keyed with an adjustment screw 291. The transmission rod 29 is conveniently rotated by adjusting the screw 291, and this design improves the convenience of operation.

[0035] In this embodiment, two fixing plates 23 are fixed in the cavity 22, and the double-ended screw rod 24 passes through the fixing plates 23 and is rotatably connected to the fixing plates 23. The fixing plates 23 support the double-ended screw rod 24, ensuring the stability and smoothness of the double-ended screw rod 24 when rotating.

[0036] In this embodiment, the cross-section of the clamping plate 27 is L-shaped, and the clamping plate 27 is fixedly connected to the movable plate 26 by bolts. The bolt fixing method ensures the installation reliability of the clamping plate 27, and the L-shaped design is conducive to the stable positioning of the clamping plate 27 on the lithium battery 4.

[0037] In this embodiment, the four corners of the bottom of the power exchange cabinet 1 are fixedly connected with support feet 11 by bolts, and the support feet 11 are fixedly connected to the power exchange cabinet 1 by bolts.

Because the worm 290 is engaged with the worm wheel 28, the worm wheel 28 rotates and drives the double-headed screw 24 to rotate, and the movable plates 26 on both sides slide along the guide rods 25 on both sides. At the same time, the movable plates 26 drive the splints 27 to move. When the two splints 27 are adjusted to a suitable gap, the user stops rotating the adjusting screw 291. At this time, the user can place the lithium battery 4 between the two splints 27.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
