Description

Automotive back butterfly window opening-closing lock catch

Technical field

The present invention relates to a kind of opening-closing lock catch of the manipulation device that is used for the automotive back butterfly window opening and closing, particularly automotive back butterfly window.

Background technology

The part automobile particularly back side window of minicar is to be designed to butterfly type window; Be that glass for vehicle window is not that fore-and-aft direction along automobile carries out opening and closing; One side of its glass for vehicle window is to carry out opening and closing along the direction vertical with automobile side, makes glass for vehicle window one side can open certain gap outwardly.

The opening and closing of automotive back butterfly window are to handle control by automotive back butterfly window opening-closing lock catch; Shown in figure 13; This snap close is made up of vehicle body Connection Block 1, glass Connection Block 3, control crank 2, pivoted arm 5 and position-limiting spring leaf 9, and vehicle body Connection Block 1 is hinged through bearing pin with pivoted arm 5 one ends, and pivoted arm 5 other ends and control crank 2 one ends are hinged through bearing pin; Control crank 2 other ends and glass Connection Block 3 are hinged through bearing pin, and pivoted arm 5 is the sub-elliptical cylindricality with the hinged end of control crank 2; Position-limiting spring leaf 9 is a sheet metal; It is fixed on the inner surface of control crank 2, and when snap close was in complete retracted state, position-limiting spring leaf 9 was between control crank 2 and pivoted arm 5; And position-limiting spring leaf 9 is outside standing shape at the position between control crank 2 and elliptical cylinder-shape pivoted arm end; Be at snap close and open fully or during retracted state, the pivoted arm end of this elliptical cylinder-shape will contact with the outside ledge extruding of position-limiting spring leaf 9, thus the withdrawal of prevention snap close or open.

The automotive back butterfly window opening-closing lock catch of this kind structure is to stop the withdrawal of snap close or open by being fixed on being used between interior position-limiting spring leaf of control crank and the elliptical cylinder-shape pivoted arm end; Withdrawal and open mode with the locking snap close can not closed and open automotive back butterfly window easily in vehicle traveling process.Because position-limiting spring leaf is a sheet metal, metal material has certain fatigue limit, and long-term use can make its elasticity weaken; Thereby make the locking of withdrawal and open mode of snap close unreliable; And long-term the use also makes position-limiting spring leaf produce fracture easily, snap close damaged, thereby influence complete vehicle quality.

Summary of the invention

The purpose of this invention is to provide a kind of automotive back butterfly window opening-closing lock catch, make the locking of withdrawal and open mode of snap close reliable, and long-term use can not influence the quality of snap close.

Automotive back butterfly window opening-closing lock catch according to the invention comprises vehicle body Connection Block, glass Connection Block, control crank and pivoted arm, and vehicle body Connection Block and pivoted arm one end are hinged, and the pivoted arm other end and control crank one end are hinged; The control crank other end and glass Connection Block are hinged, and the hinged end of pivoted arm and control crank is the cylinder bodily form, and the periphery of this pivoted arm end is provided with to be opened positive stop lug boss and close positive stop lug boss; Inner surface at control crank is horizontally arranged with retaining convex rib; It is at control crank and have between the cylinder pivoted arm end of positive stop lug boss, when snap close is in full open position, opens positive stop lug boss and pushes with retaining convex rib and contact; Regain to stop snap close; When snap close is in complete retracted state, close positive stop lug boss and contact with the retaining convex rib extruding, open to stop snap close.

Opening positive stop lug boss is arcwall face with the end face of closing positive stop lug boss; The surface of retaining convex rib is the face of cylinder; Withdrawal and open mode guaranteeing snap close can be able under the prerequisite of positive lock; Can make the withdrawal of snap close and open easy and flexible, to reduce the operation strength of automotive back butterfly window opening and closing.

Vertical fixing has block on the vehicle body Connection Block; The axis of the swivel pin axis hole on this block and the vehicle body Connection Block has angle; This angle is consistent with the angle of inclination at vehicle window frame edge, and when snap close was installed, this stop-surface can be fitted with the vehicle window frame edge; Thereby the butterfly window opening-closing lock catch dress that can prevent the vehicle right and left both sides is wrong, also can strengthen the intensity of vehicle body Connection Block simultaneously.

The glass Connection Block of this automotive back butterfly window opening-closing lock catch is installed on the glass for vehicle window is connected, and the vehicle body Connection Block is screwed on body side wall, realize that promptly this latches in the installation on the automotive back butterfly window with glass for vehicle window.

During operation, pull control crank, can snap close be opened, automotive back butterfly window is opened, and when closing back butterfly window, only with hand retracts control crank, snap close is regained got final product with hand.

Automotive back butterfly window opening-closing lock catch according to the invention adopts two positive stop lug boss and the retaining convex rib on the control crank on the pivoted arm cylinder end to come opening with retracted state of snap close carried out limitation locking; Its locking is very reliable; Owing to removed the position-limiting spring leaf in the existing structure; Quality problems such as snap close inefficacy, damage can not occur through long-term the use yet, simplify the structure and the assembly process of snap close simultaneously yet, reduce the cost of snap close.
