[0021] This utility model provides a high-voltage lithium battery protection structure for a cordless vacuum cleaner, including a base 1 installed inside the vacuum cleaner. A damping spring vibration damper 5 is fixedly installed on the base 1. The damping spring vibration damper 5 is a composite vibration damping device combining the low-frequency characteristics of a steel spring and the high energy dissipation characteristics of a damping material. Its core function is to absorb vibration energy through the elastic deformation of the spring, while simultaneously using the damping material to convert and dissipate the vibration energy into heat energy, thereby achieving effective isolation and attenuation of mechanical structure vibration. This is a known prior art technology. By setting up the damping spring vibration damper 5, damping and vibration reduction are provided for the lithium battery, thereby achieving the purpose of protecting the lithium battery. The vibration damping end is fixedly installed with a box 6. The box 6 is square in shape. The box 6 is set to support the installation of rubber protrusions 3. The rubber protrusions 3 are fixedly installed on the box 6. By setting the rubber protrusions 3, it is easy to support the placement of the lithium battery body 4.

The strip frame 26 is fixedly installed at one end of the slide plate 21. The drive rod 25 slides inside the strip frame 26. When the drive rod 25 makes a circular motion, it will drive the slide plate 21 to slide linearly along the inner wall of the limiting groove 29.
[0024] A dual-output shaft motor 211 is fixedly installed on the receiving plate 210. The dual-output shaft motor 211 is horizontally set and has forward and reverse rotation functions. The dual-output shaft motor 211 is set to drive the lead screws 212 on both sides to rotate. The lead screws 212 are fixedly installed on the shaft end of the dual-output shaft motor 211, and the thread directions of the lead screws 212 at both ends of the dual-output shaft motor 211 are opposite.
[0025] One end of the lead screw 212 is rotatably connected to the inside of the frame 23. A slider 216 is threaded onto the lead screw 212. The slider 216 is square in shape and slides on the inner wall of the frame 23. The slider 216 is used to support the installation of the mounting bracket 27.

[0027] The inner wall of the mounting bracket 27 is slidably provided with a second slide rod 221. A second clamping plate 217 is fixedly installed at one end of the second slide rod 221. The clamping surfaces of the first clamping plate 219 and the second clamping plate 217 are both equipped with rubber pads with anti-slip textures. By setting the first clamping plate 219 and the second clamping plate 217 with anti-slip textured rubber pads, the clamping stability of the lithium battery is improved.
[0028] A second spring 218 is fixedly installed on the inner wall of the mounting bracket 27. One end of the second spring 218 is fixedly connected to the second clamping plate 217. The second spring 218 plays a buffering role during the clamping process.
[0029] A second damper 220 is fixedly installed on the inner wall of the mounting bracket 27. The damping end of the second damper 220 is fixedly connected to the second clamping plate 217. The second damper 220 is a device that dissipates energy and suppresses or reduces mechanical vibration and impact by providing resistance to motion. Its core principle is to convert kinetic energy into other forms of energy such as heat energy through friction, fluid resistance, electromagnetic effect or other forms and dissipate it, thereby quickly calming the oscillation of the system and achieving the purpose of stabilizing the structure, protecting the equipment or improving comfort. It belongs to the existing known technology. By setting the second damper 220, it plays the purpose of damping and reducing vibration during the clamping process, which is beneficial to improving the stability of lithium battery.
[0030] There are two frames 23, and the two frames 23 are square frames. The purpose of setting the frames 23 is to limit the movement of the slider 216.
[0031] During the installation of the lithium battery body 4, the lithium battery body 4 is placed on the rubber protrusion 3, and then the drive motor 24 is started. The drive motor 24 drives the turntable 28 to rotate. When the turntable 28 rotates, it drives the drive rod 25 to perform a circular motion. When the drive rod 25 performs a circular motion, it drives the two side slide plates 21 to slide towards each other along the inner wall of the limiting slide groove 29 through the strip frame 26. When the two side slide plates 21 slide towards each other, they drive the two side frame bodies 23 to move towards each other through the bracket 22 and the receiving plate 210 until the first clamping plates 219 on both sides contact and press against the surface of the lithium battery body 4.
[0032] Then, the dual-output shaft motor 211 is started. The dual-output shaft motor 211 drives the lead screws 212 on both sides to rotate. Since the threads of the lead screws 212 on both sides are in opposite directions, when they rotate, they will drive the sliders 216 on both sides to slide towards each other along the inner wall of the frame 23. When the frames 23 on both sides slide towards each other, they will drive the second clamping plates 217 on both sides to move towards each other through the mounting bracket 27 and the second slide bar 221 until the second clamping plates 217 on both sides contact and press against the surface of the lithium battery body 4. Through the above settings, it is easy to The system clamps and fixes lithium battery bodies 4 of different sizes. By setting a first clamping plate 219 and a second clamping plate 217 with anti-slip textured rubber pads, the clamping stability of the lithium battery is improved. At the same time, the first spring 215 and the second spring 218 play a buffering role during the clamping process, which helps to protect the lithium battery body 4. Furthermore, by setting a first damper 214 and a second damper 220, together with the damping spring vibration damper 5 and the rubber protrusions 3, the system plays a damping and vibration reduction role, reducing the impact of vibration on the lithium battery.
