In the ventilation structure of the elevator car, upper ventilation holes and lower ventilation holes facing the inner side of the elevator car need to be opened on the top and bottom of the car wall. The upper ventilation holes and lower ventilation holes facing the inner side of the elevator car affect the appearance of the elevator car. The inner side of the car wall covers the interior decoration. The car wall blocks the upper and lower ventilation holes, which is costly and will increase the weight of the car or reduce the effective volume of the car

Embodiment 1
[0053] like figure 2 , image 3 and Figure 4 As shown, the car wall structure of the elevator car includes a car wall plate 1, a skirting plate 2 and a sealing plate 3;
[0054] The skirting board 2 includes an upper horizontal surface 21 and a vertical surface 22 of the skirting which are connected together;
[0055] The outer end of the upper horizontal surface 21 of the kick is connected to the upper end of the vertical surface 22 of the kick;
[0056] The car wall panel 1 includes a car wall vertical surface 11 and a car wall lower transverse folding surface 12;
[0057] The inner end of the lower transverse folding surface 12 of the car wall is connected to the lower end of the vertical surface 11 of the car wall;
[0058] The lower transverse folded surface 12 of the car wall and the upper transverse surface 21 of the skirting are attached and installed;
[0059] Described sealing plate 3, its lower end is sealed with described car wall lower transverse folding surf...
Embodiment 2
[0065] Based on the elevator car wall structure of Implementation 1, at least one acoustic cavity segment 8 is mounted on the sealing plate 3;
[0066] like Figure 5 As shown, the acoustic cavity dividing sheet 8 is used to divide the anechoic air duct into a plurality of sub-acoustic cavities to eliminate the 200-400 Hz acoustic cavity mode of the anechoic air duct.
[0067] Preferably, the acoustic cavity dividing sheet 8 can move up and down or back and forth on the sealing plate.
[0068] Preferably, the sealing plate is provided with guiding and positioning grooves;
[0069] The acoustic cavity dividing sheet 8 is detachably assembled to a selected position of the guide positioning groove through a positioning rod.
[0070] The cavity inside the muffler duct may have a size-related acoustic cavity mode at 200-400Hz, while the main frequency of the hoistway noise source is around 300Hz. Therefore, in order to avoid resonance of the acoustic cavity, in the car wall stru...
Embodiment 3
[0072] Based on the elevator car car wall structure of implementing one or two, the sound-absorbing material 9 is pasted on the side of the air duct of the sealing plate 3, the vertical surface of the car wall 11 or the lower transverse folding surface 12 of the car wall surrounding the noise-absorbing air duct.
[0073] Preferably, the sound-absorbing material 9 is made of sound-absorbing cotton or other sound-absorbing materials.
[0074] Implementation of the third elevator car car wall structure, the muffler air duct also has the function of muffler while ventilating the car.

Abstract
The invention discloses an elevator car wall structure. A skirting board of the structure comprises a skirting upper transverse face and a skirting vertical face which are connected together, and a car wall board of the elevator car wall structure comprises a car wall vertical face and a car wall lower transverse folding face. The car wall lower transverse folding face and the skirting upper transverse face are installed in an attached manner. The lower end of a sealing plate is in sealing connection with the car wall lower transverse folding surface, and the upper end, the front end and the rear end of the sealing plate are in sealing connection with the car wall vertical face, so that the sealing plate, the car wall vertical face and the car wall lower transverse folding surface jointly define a silencing air duct; and an air inlet hole is formed at the front portion of the sealing plate, and a ventilation hole is formed in the car wall lower transverse folding face and the skirting upper transverse face which are installed together in an attached manner and located at the rear portion of the sealing plate. The lower end of the skirting vertical face of the skirting board is used for abutting against a bottom plate of an elevator car. According to the elevator car wall structure, the overall contour size of the car wall structure is not increased while the ventilation area is not changed and noise in a car is reduced, interference with other parts of the car is avoided, meanwhile, no additional technology is needed in the installation process, and installation is convenient.
Description
technical field [0001] The invention relates to an elevator car, in particular to an elevator car car wall structure. Background technique [0002] The elevator car system is based on the relevant standards of elevator manufacturing and installation safety regulations, among which GB7588-2003 stipulates that the upper and lower parts of the elevator car must have ventilation openings, and the effective area of the upper and lower ventilation openings is not less than the effective area of the elevator car. 1%. At present, the single-layer car wall car structure of most elevators is as follows: figure 1 shown. The car is mainly divided into car top, car wall, and car bottom; due to the need for ventilation area, when the traditional car is assembled, a certain gap is left between the car wall and the car top and car bottom to ensure sufficient ventilation area. Larger gaps will cause shaft noise to be transmitted directly to the car through the gaps, resulting in poor ...
