Actuator module structure of noise reduction

一种降低噪音的驱动模组结构

Abstract

本实用新型公开了一种降低噪音的驱动模组结构,其包括驱动件、受所述驱动件驱动进行旋转运动的螺杆、与所述螺杆配合传动的螺母以及与所述螺母固定连接的固定座,还包括平行位于所述螺杆上方的钢带以及将所述钢带压在所述固定座上的压盖,所述固定座的上表面设置有凸起部,所述凸起部上表面与所述固定座的侧面通过斜坡面过渡连接,所述斜坡面上与所述钢带接触的部位设置有若干橡胶片。本实用新型通过在固定座与钢带接触的位置设置橡胶片,避免了钢带与固定座表面的金属接触,一方面降低了金属接触产生的噪音;另一方面也防止了双金属腐蚀,大大提高了钢带的使用寿命。
The utility model discloses an actuator module structure of noise reduction, it includes the driving piece, receives driving piece drive carry on rotary motion the screw rod, with the driven nut of screw rod cooperation and with nut fixed joint's fixing base includes still that the parallel is located the steel band and the general of screw rod top the steel band is pressed gland on the fixing base, the upper surface of fixing base is provided with the bellying, the bellying upper surface with the slope transitional coupling is passed through to the side of fixing base, on the slope with the position of steel band contact is provided with a plurality of sheet rubbers. The utility model discloses a set up the sheet rubber in fixing base and the position that the steel band contacted, avoided the metal touch of steel band with the fixing base surface, reduced the noise that metal touch produced on the one hand, on the other hand has also prevented bimetallic corrosion, has improved the life of steel band greatly.
