Protection device for rocker arm type manual skylight opening mechanism

Abstract

The invention discloses a protection device for a rocker arm type manual skylight opening mechanism. The protection device for the rocker arm type manual skylight opening mechanism comprises a rockerarm seat, a coupling block, a relief spring, a bushing, a gland and a driving shaft. The gland, the bushing, the relief spring, the coupling block and the rocker arm seat are sequentially mounted on the driving shaft in the axial direction. The rocker arm seat is driven by a rocker arm to rotate around the axial direction and is provided with a circle of tooth grooves around the axial direction. The coupling block is provided with a circle of latches matched with the tooth grooves around the axial direction. A coupling hole is formed in the axial end surface of the coupling block. The cross section, perpendicular to the axial direction, of the coupling hole is in a non-revolving type and matches with the cross section of the driving shaft in shape. The both ends of the relief spring are abutted to the coupling block and the bushing. The bushing and the coupling block are abutted in the circumferential direction and slidably connected in the axial direction. According to the protectiondevice for the rocker arm type manual skylight opening mechanism, extreme protection is realized through tooth jumping of the internal mechanism, the skylight opening mechanism is protected while excessive operation is avoided, and anti-misoperation safety performance is further improved.

Description

technical field [0001] The invention relates to the technical field of sunroof opening mechanisms, in particular to a rocker-arm type manual sunroof opening mechanism protection device. Background technique [0002] As the standard configuration of many cars, the car sunroof is installed on the roof of the car, which can effectively circulate the air in the car, increase the entry of fresh air, and bring healthy and comfortable enjoyment to the car owner. [0003] The sunroof opening mechanism can be divided into electric and manual according to its starting mode. The electric sunroof is controlled by the control button, while the manual sunroof is opened and closed by artificial hands. The manual sunroof opening mechanism is a mechanical mechanism used to control and change the opening and closing of the sunroof and the degree of opening in the manual sunroof. The rocker arm type manual sunroof opening mechanism is the most common type of manual sunroof opening mechanism. ...

AI Technical Summary

Problems solved by technology

Since the manual sunroof opening mechanism is not easy to judge whether it has been fully opened or fully closed during human operation, it may occur that the operator continues to shake the rocker arm after the sunroof has been fully opened or fully closed, which will cause the teeth of the meshing part to jam and the mechanism Wear and tear, in severe cases, it may even directly cause damage to the sunroof opening mechanism and make it unusable
