Description

Technical Field

[0001] The present invention relates to the technical field of teaching aids, and specifically relates to a solid-state battery safety performance practical training platform. Background Art

[0002] A solid-state battery is a battery technology. Different from the currently widely used lithium-ion batteries and lithium-ion polymer batteries, a solid-state battery is a battery that uses solid electrodes and solid electrolytes. Since the scientific community believes that lithium-ion batteries have reached their limits, solid-state batteries have been regarded as batteries that can inherit the position of lithium-ion batteries in recent years. The solid-state lithium battery technology uses glass compounds made of lithium and sodium as conductive substances to replace the electrolyte of traditional lithium batteries, greatly improving the energy density of lithium batteries.

[0003] In the patent with the publication number CN115273601B, a flight simulator based on mixed reality is disclosed. The present invention includes a flight simulator body, a mixed reality helmet, a cockpit seat, a base, and a cockpit housing. A slide rail is provided in the middle of the upper surface of the base. The cockpit seat is slidably connected to the inner surface of the slide rail through pulleys provided on the lower surface. A cockpit instrument sunshade is fixedly connected to the upper surface of the cockpit housing. A switch control panel and a joystick are provided on the upper surfaces of both sides of the cockpit instrument sunshade close to the slide rail. An instrument panel is installed on the upper surface of one end of the cockpit instrument sunshade close to the slide rail. A camera is provided at the front end of the outer surface of the mixed reality helmet; by displaying a real scene picture at the required position in the VR virtual environment, it can achieve that in the virtual environment with an omnidirectional view, the interior of the physical cockpit and the operations of the driver can be seen simultaneously, solving the problem that using a projection dome screen in a flight simulator cannot meet the omnidirectional view requirement.

[0004] The above patent has the following problems:

[0005] Since the low-altitude aircraft training platform is relatively high from the ground, it is very inconvenient for training personnel to get on and off the training platform. Therefore, an extra ladder is prepared. Due to the large shaking amplitude of the training platform during use, the extra ladder can only be used when the training platform is completely stationary and lowered to the lowest position. This requires additional personnel to carry and place the ladder, resulting in a low degree of automation and increasing the labor intensity of the staff; there is a risk of combustion and fire in solid-state batteries. Therefore, it is necessary to train the ability of training personnel to handle battery fires. In the prior art, it is not convenient to add this safety training during flight training. Therefore, we have developed a solid-state battery safety performance practical training platform. Summary of the Invention

Open the fire extinguisher box, take out the simulated fire extinguisher, and walk down the training table through the folding ladder mechanism. After pulling out the safety pin on the simulated fire extinguisher, hold the grip and press the pressing handle. The bottom of the pressing handle squeezes the button, and the button turns on the directional signal transmitter and the white LED light. When the white LED light irradiates all the directional signal receivers of the smoke alarm, it means that the directional signal transmitter sends signals to all the directional signal receivers, and the directional signal receivers turn off the smoke generators. This can facilitate the training personnel to conduct practical training on the fire disposal of the solid-state battery when there are safety problems with the solid-state battery of the low-altitude aircraft, and improve the training effect.

[0029] The folding ladder mechanism includes an upper ladder 6 and a lower ladder 5. The lower ladder 5 is hinged at the edge of the base 1. The top of the lower ladder 5 is hinged to the bottom of the upper ladder 6. A through hole is arranged on the upper side of the lower ladder 5. An arc rod 17 is slidably arranged in the through hole. The center of the arc rod 17 coincides with the hinge point of the lower ladder 5 and the upper ladder 6. The upper end of the arc rod 17 is fixedly connected to the upper ladder 6. A spring 16 is movably sleeved on the rod wall of the arc rod 17 above the lower ladder 5. The spring 16 is always in a compressed state. A circular block 18 is fixedly arranged at the lower end of the arc rod 17. The circular block 18 can prevent the arc rod from disengaging from the through hole. The diameter of the circular block 18 is larger than the aperture of the through hole.

[0030] The linkage mechanism includes an annular plate 12 and a housing 4. The annular plate 12 is arranged between two folding ladder mechanisms. Support rods 3 are fixedly provided between the four corners of the annular plate 12 and the base 1. The housing 4 is fixedly arranged in the middle of the upper end of the base 1. Screws 19 are rotatably provided on both sides of the housing 4. One ends of the two screws 19 penetrate into the housing 4 and are fixedly provided with first bevel gears 14.

When conducting actual operation on the safety performance of the solid-state battery, after the telescopic unit 13 drives the training platform 10 to descend to the bottom, the central processing unit activates multiple smoke generators 11, red LED lights, and directional signal receivers. The smoke generated by the smoke generator 10 can simulate a battery fire under the illumination of the red LED lights. The motor 2 starts and its output end rotates counterclockwise. The motor 2 drives the two lower ladders 5 and the upper ladder 6 to reset. Open the fire extinguisher box 7, take out the simulated fire extinguisher 23, and walk down the training platform 10 through the folding ladder mechanism. After pulling out the safety pin on the simulated fire extinguisher 23 and holding the handle 24, press the pressing handle 26. The bottom of the pressing handle 26 presses the button 25. The button 25 turns on the directional signal transmitter and the white LED light. When the white LED light irradiates all the directional signal receivers of the smoke alarm 11, it means that the directional signal transmitter sends signals to all the directional signal receivers. The directional signal receivers turn off the smoke generator 11. In this way, when a safety problem occurs in the solid-state battery of the low-altitude aircraft, it is convenient for the training personnel to conduct actual operation training on the fire disposal of the solid-state battery, improving the training effect.
