Embodiment 1

[0034] A shock-absorbing mechanism for an elevator car, such as figure 1 As shown, it includes an elevator car 100, and a modular shock absorbing mechanism 200 arranged at the bottom of the elevator car. The modular shock absorbing mechanism 200 includes an upper support plate 210, a lower support plate 220, and a The extruding buffer mechanism 300 between the supporting plate 210 and the lower supporting plate 220 is surrounded by a flexible shock-absorbing base 400 .

[0035] In this technical solution, the damping mechanism is mainly composed of two parts, that is, the squeeze buffer mechanism 300 and the flexible damping base 400, which are further divided into several small damping modules, so it is called the modular damping mechanism 200. The squeeze buffer mechanism 300 has been innovatively improved on the basis of traditional shock absorbing springs, and in order to ensure the shock absorbing effect and to ensure that the squeeze buffer mechanism 300 fails unexpected...

Abstract

The invention discloses a shock absorption mechanism used for an elevator car, and relates to the technical field of elevator equipment. The shock absorption mechanism comprises the elevator car and amodular shock absorption mechanism which is arranged at the bottom part of the elevator car, the modular shock absorption mechanism comprises an upper support plate, a lower support plate, and an extrusion buffer mechanism which is arranged between the upper support plate and the lower support plate, and the periphery of the extrusion buffer mechanism is provided with a flexible shock absorptionmatrix in a surrounded manner. A plurality of levels of shock absorption modules are arranged in the inner part of the extrusion buffer mechanism, each shock absorption module cooperatively work; theflexible shock absorption matrix is made of a rubber layer and a thin steel layer at intervals, the bearing capacity of the modular shock absorption mechanism is increased at the same time of dampingbuffer, and the modular shock absorption mechanism from being easily damaged due to excessive pressure is effectively prevented. The modular shock absorption mechanism cooperates with each other to ensure the damping effect together, so that the problems the existing elevator car damping mechanism damping effect is poor and the loss is easy are solved.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a shock absorbing mechanism for an elevator car. Background technique [0002] The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of main components such as the car floor, car wall, car roof, and car door. In order to improve the ride comfort of the users in the car, a shock absorbing mechanism is generally installed in the car bottom. The shock absorbing mechanism of the existing elevator car is generally composed of a shock absorbing spring to form a shock absorbing mechanism. When the weight of the car is carried When the shock-absorbing spring is relatively large, other shock-absorbing devices are not effective in helping it to buffer when the shock-absorbing spring is subjected to a strong impact, resulting in serious deformation of the shock-absorbing spring and reducing the shock-absorbi...
