[0002] The car is the part of the car body that carries passengers or other loads. The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of the main parts such as the car bottom, car wall, car top, car door, etc., and its internal clear height should be at least 2m.
[0003] The elevator car of the prior art has the following disadvantages: 1. The elevator car vibrates and shakes after people enter the elevator or the elevator stops descending, and people are less comfortable when riding the elevator; 2. People come and go in the elevator car, and various smells such as cigarettes and food remain in the elevator car. Therefore, improvements are made to the above problems. Utility Model Content

The shock-absorbing plate a, foam aluminum, shock-absorbing plate b, springs, torsion springs, etc. cooperate to improve the overall vibration reduction effect; the UV lamp, photocatalyst, activated carbon, etc. in the deodorizing frame cooperate to achieve a better deodorizing effect.
[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a bottom shock-absorbing device of an elevator car, comprising an elevator car, the elevator car is rotatably connected to a rotating frame through a rotating rod, the rotating rod is surrounded by a torsion spring, the rotating frame is installed with a wire rope, the wire rope is installed with a slide plate, the slide plate is slidably connected with a shock-absorbing frame, a shock-absorbing plate a is bonded in the elevator car, the shock-absorbing plate a is bonded with foam aluminum, the foam aluminum is located below the shock-absorbing plate b, the shock-absorbing plate b is bonded with a bottom plate, a deodorizing frame is installed in the elevator car, the deodorizing frame is installed with an exhaust fan, the exhaust fan is located on the inner side of a UV lamp, and the UV lamp is located behind a photocatalyst.
[0006] Preferably, one end of the torsion spring abuts against a rotating frame, and the rotating frame is rotatably connected to a roller.
[0007] Preferably, the steel wire rope is connected around a spring, and the spring is located on the inner side of the vibration damping frame.
[0008] Preferably, the vibration damping frame is fixedly connected to the bottom of the elevator car, and the vibration damping plate a is made of polyurethane.
[0009] Preferably, the photocatalyst is coated on the inner surface of the deodorizing rack, and a mesh plate is installed inside the deodorizing rack.
[0010] Preferably, the mesh plate is located above the activated carbon, and the activated carbon is filled between the mesh plate and the deodorizing rack.
[0011] Preferably, an air outlet is provided at the bottom of the deodorizing rack, and the shock absorbing plate b is made of high-impact polystyrene.
[0012] The beneficial effects of the utility model are:
[0013] 1. The damping plate a, foam aluminum, damping plate b, springs, torsion springs, etc. are used together to improve the overall damping effect; the damping plate b made of high-impact polystyrene is bonded to the bottom of the elevator car, and micron-sized rubber particles are added to it and the polystyrene and rubber particles are connected together by grafting. When impacted, the tip stress of the crack extension will be released by the relatively soft rubber particles. Therefore, the expansion of cracks is hindered and the impact resistance is improved. The foam aluminum at the bottom of the shock-absorbing plate b has high damping shock-absorbing performance and impact energy absorption rate. The damping performance is 5-10 times that of metal aluminum. When the foam aluminum with a porosity of 84% is 50% deformed, it can absorb more than 2.5MJ / m3 of energy. The shock-absorbing plate a below the foam aluminum is made of polyurethane, which has good elasticity and toughness and can achieve good vibration reduction effect. When the elevator car moves down and contacts the ground, the roller on the bottom turntable contacts the ground, and the turntable rotates outward around the elevator car with the turn rod as the axis, squeezing the torsion spring at the turn rod. The turntable is connected to one end of the wire rope, and the other end of the wire rope is connected to the slide plate inside the shock-absorbing frame. When the turntable continues to rotate, it drives the wire rope to move and compress the spring, which can have a buffering effect to avoid large vibration when the elevator car contacts the ground after stopping.
[0014] 2. The UV lamp, photocatalyst, activated carbon, etc. in the deodorization rack work together to achieve a good deodorization effect; deodorization racks are installed on both sides of the elevator car. The exhaust fan in the deodorization rack is started to extract the air in the elevator car, and the extracted air is sent to the deodorization rack. After the UV lamp in the deodorization rack is powered on, it emits ultraviolet rays forward. The ultraviolet rays irradiate the surface of the photocatalyst coated on the surface of the deodorization rack, producing a strong catalytic oxidation effect, which can effectively degrade toxic and harmful gases in the air, and has a good deodorization effect on cigarette odors, garbage odors, etc. After UV photolysis, the air is continuously transported downward to contact with the activated carbon below. The activated carbon has a strong adsorption effect and can adsorb unpurified odors in the air. The adsorbed air is removed through the air outlet, which can continuously deodorize the air in the elevator car. BRIEF DESCRIPTION OF THE DRAWINGS
