Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in figures 1 to 6, it present embodiments provides a kind of rear window opener, including locking device 1, limit base 2 and opens
Opening device 3.Locking device 1 is cylindrical, and vertical removable is mounted on the rear window 4, and the outer wall of locking device 1 is equipped with
Rotating handle 11, the first set lever 12 and the second set lever 13, rotating handle 11, the first set lever 12 and second lock
Tight handle 13 rotates synchronously, wherein rotating handle 11 is vertically set on locking device 1, the first set lever 12 and second lock
Tight handle 13 is located at the different zones of cylindric locking device 1, and for the ease of operation, the length of rotating handle 11 is more than first
The length of set lever 12 and the second set lever 13, and when being in semi-open state due to rear window, locking device 1 and limit base
Angle between 2 changes, therefore the axis of the second set lever 13 and locking device 1 is in certain inclination angle, the inclination angle energy
Enough meet in the first set lever 12 and the rotation to limit base 2 of the second set lever 13.The limit base 2 of the present embodiment is mounted on and drives
It sails on room skeleton 5, limit base 2 has the card slot that can engage above-mentioned first set lever, 12 and second set lever, 13 end
201, by diagram it is found that when the first set lever 12 or the second set lever 13 fasten with card slot, rotating handle 11 is water
It puts down to setting, the first set lever 12 and the second set lever 13 are vertically to setting, which can revolve in order to which user grasps
Change hands handle.
In conjunction with shown in attached drawing 6, when needing to open rear window, rear window 4 is opened by opening device 3, at this time the first locking hand
Handle 12 and the second set lever 13 are not connected to limit base 2；When needing that rear window is made to be closed, by rear window 4 pull back to
At closing, and rotating handle 11 is operated, the first set lever 12 turns in card slot 201, passes through 12 He of the first set lever
The closing for being implemented in combination with rear window of card slot 201；When need to be semi-open by rear window, operation rotating handle 11 releases the first set lever
12 and card slot 201 connection, and by push and pull rear window the second set lever 13 is located near limit base 2, again operation revolve
Changing hands handle makes the second set lever 13 be placed in card slot 201, passes through the realization rear window of the second set lever 13 and card slot 201
It is semi-open.
Specifically, the above-mentioned opening device 3 of the present embodiment can be gas spring, gas spring automatically turns on rear window, is not necessarily to hand
Dynamic, the stroke of gas spring determines the angle that rear window fully opens, using gas spring open a window it is steady, be easy to control.Certainly other are past
As long as multiple motion disclosure satisfy that the unlatching of rear window requires to can also be used as the opening device of the present embodiment.
Above structure can realize the semi-open state of rear window, ensure the natural stream for driving room air and outdoor air
It is logical, avoid high wind blow-through from entering in driver's cabin, while when air regulator is opened after reduce as far as possible again occupies excessive space, operation letter
