Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1-3 shows the structure of the rain wiper of camera protective cover that the embodiment of the present invention provides.Illustrate only part related to the present invention for convenience of explanation.
This rain brush comprises base plate 1, reflective optocoupler 2, fixed mount 3, slide block 4, brace 5, guide rail 6, driven pulley 7, belt 8, pinch roller 9, belt pulley 10, compressing tablet 11, spring 12, shell 13, motor 14, sealing joint strip 15, rain brush large arm 16, spring 17, rain brush forearm 18, adhesive tape clamping plate 19, rubber strip 20.
Brace 5 and slide block 4 are fixed together by two plus screw, and brace 5 clamping belt, slide block 4 is enclosed within guide rail 6.Brace 5 is connected to rain brush large arm 16, and rain brush large arm 16 is connected with rain brush forearm 18 by screw, and rain brush forearm 18 is connected with adhesive tape clamping plate 19 by screw, and adhesive tape clamping plate 19 are connected with rubber strip 20.Rain brush large arm 16 is connected with rain brush forearm 18 by spring 17, for rain brush forearm 18 provides pretightning force to make rubber strip 20 be adjacent to glass vision panel.
Belt 8 is wrapped on belt pulley 10 and two driven pulleys 7, and two pinch rollers 9, respectively at the left and right sides of belt pulley 10, push down belt 8.Left side pinch roller is fixed, and right side pinch roller provides pretightning force to compress belt by compressing tablet 11 by spring 12.Driven pulley 7 is arranged on the fixed mount 3 on base plate 1.
