The invention discloses an elevator car buffer capable of automatically expanding the butt joint area. The elevator car buffer comprises a base and a positioning sleeve, a hydraulic shaft is installed on the surface of the base, the top end of the hydraulic shaft is connected with a shaft center, the surface of the shaft center is connected with a buffer spring, and the top end of the shaft center is connected with a collided head. According to the lift car buffer capable of automatically expanding the butt joint area for the elevator, in the process that the elevator is close to the lift car buffer, the elevator firstly makes contact with a vertical rod, a certain acting force is applied to the vertical rod, a linkage plate inclines by an angle on the surface of an eccentric shaft, and an ejector rod is driven to apply a certain supporting force to a bearing block; the supporting plate rotates on the surface of the rotating shaft, the contact face of the supporting plate and the contact face of the silencing pad are located on the same horizontal line, the contact area of the lift car buffer is increased, pressure borne by the lift car buffer is reduced, and the service life of the lift car buffer is prolonged.

    本发明公开一种电梯用可实现自动撑开对接面积功能的轿厢缓冲器,包括:底座和定位套,所述底座的表面安装有液压轴,所述液压轴的顶端连接有轴心,所述轴心的表面连接有缓冲弹簧,所述轴心的顶端连接有受撞头。该电梯用可实现自动撑开对接面积功能的轿厢缓冲器,通过电梯在靠近轿厢缓冲器的过程中,电梯首先与立杆进行接触,对立杆施加一定的作用力,使得连动板在偏心轴的表面发生角度倾斜,带动顶杆对承接块施加一定的支撑力,进而使得支撑板在转轴的表面进行旋转,使得支撑板的接触面与消音垫的接触面位于同一水平线上,增大轿厢缓冲器的接面积,减少了轿厢缓冲器受到压力,增大轿厢缓冲器的使用寿命。
