Description

Technical Field

[0001] The invention relates to the field of lithium ion batteries, and in particular to a device for improving the fast charging performance of lithium ion batteries. Background Art

[0002] Lithium-ion battery is a secondary battery that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is intercalated and deintercalated between the two electrodes: when charging, Li+ is deintercalated from the positive electrode and intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.

[0003] After searching, the applicant found that a Chinese patent disclosed "a lithium-ion battery charging device", and its publication (announcement) number is "CN214124870U". The patent mainly includes a supporting device, a shock-absorbing device, a protective device, a main body device and an energy-saving device. The supporting device includes a supporting column, a display screen and a start switch. The shock-absorbing device includes a transverse block, a slot and a shock-absorbing column. Several slots are rectangular slots. The protective device includes a protective box, a heat dissipation strip, a handle, a box door and a visual glass. The main body device includes a battery body and a backup battery. The energy-saving device includes a support rod, a power display bar, a USB interface and a socket. In the present invention, a display screen and a power display bar are provided to intelligently display various performances of each battery body in real time and remind the charging status, a voltage detection module is used to protect the lithium-ion secondary battery from charging and automatically cut off the power when fully charged, a USB interface and a socket provide power for other devices, and a heat dissipation bar dissipates the heat inside the device. However, although the heat dissipation bar is used in the comparative document to achieve the heat dissipation effect, the heat dissipation effect of a single heat dissipation bar is poor, and the lithium-ion battery will still generate high temperature during the charging process, resulting in a slow charging speed and poor performance of the lithium-ion battery, which is not conducive to user use. For this reason, we propose a device for improving the fast charging performance of lithium-ion batteries. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

The number of the fan blades is multiple and they are distributed in a circle with equal distances. By setting up the heat dissipation component, the function of dissipating heat for the lithium-ion battery can be achieved, avoiding the high temperature of the lithium-ion battery during charging, which leads to the disadvantage of reduced charging performance of the lithium-ion battery. The number of the fan blades is multiple and they are distributed in a circle with equal distances. By setting up multiple fan blades, the heat dissipation effect can be improved.

[0012] Furthermore, the lifting assembly includes a threaded sleeve rotatably connected to the top of the fixed plate, the internal thread of the threaded sleeve is connected to a threaded rod, and the top of the threaded rod is arranged on the bottom of the mounting block. By setting the lifting assembly, it is convenient for the staff to adjust the height of the charging port, so that the charging port can charge lithium-ion batteries of different models and heights, and the adaptability is enhanced.

[0013] Furthermore, the support assembly includes a telescopic sleeve fixedly connected to the top of the fixed plate, a telescopic rod is slidably connected to the inside of the telescopic sleeve, the top of the telescopic rod is fixedly connected to the bottom of the mounting block, and the mounting block is slidably connected to the inside of the telescopic sleeve through the telescopic rod, so that the mounting block can be more stable when moving.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention starts the motor, and the output end of the motor drives the first shaft and the first gear to rotate. Since the first gear is meshed with the second gear, the rotation of the first gear can drive the second gear and the second shaft to rotate. The rotation of the second shaft can drive multiple fan blades to rotate. At this time, the fan blades can blow out cold air, and the cold air will blow to the surface of the lithium-ion battery through the exhaust hole, thereby achieving the function of dissipating heat for the lithium-ion battery, avoiding the high temperature of the lithium-ion battery during charging, which leads to the disadvantage of reduced charging performance of the lithium-ion battery. By setting the above structure, the charging performance of the lithium-ion battery can be improved, and the charging and power transmission of the lithium-ion battery can be accelerated.

[0017] 2. The present invention starts two electric push rods, and the output ends of the two electric push rods drive the two clamps to move towards each other. At this time, the two clamps move to the two sides of the lithium-ion battery, so that the lithium-ion battery can be clamped and fixed on the top of the box, avoiding the phenomenon that the charging end of the lithium-ion battery is separated from the charging port due to external shaking.

[0018] 3. The present invention places the lithium-ion battery on the top of the box, connects the charging end of the lithium-ion battery to the charging port, and then the lithium-ion detection can be charged.

[0033] Working principle of the present invention: when the lithium-ion battery needs to be charged, the lithium-ion battery is first placed on the top of the box 1, and the charging end of the lithium-ion battery is connected to the charging port 5. At this time, the lithium-ion detection can be charged, and the two electric push rods 7 are started. At this time, the output ends of the two electric push rods 7 drive the two clamping plates 8 to move in opposite directions. At this time, the two clamping plates 8 move to the two sides of the lithium-ion battery, and the lithium-ion battery can be clamped and fixed on the top of the box 1, avoiding the phenomenon that the charging end of the lithium-ion battery is separated from the charging port 5 due to external shaking.
