Abstract
The utility model relates to a four-link rod door used for a baggage bin gate of a car or a bin gate of a rearmounted engine. Two four-link rod mechanisms at both sides are used to be mutually connected with a car body. The inner part of each link rod mechanism is equally provided with an L-shaped rod. The long arm end and the short arm end of the L-shaped rod are respectively hinged at the middle part of the lateral edge of the door and the car body. The short arm of the L-shaped rod is fixedly connected with a connecting block. The outer end of a moving rod in an air spring is hinged with the connecting block. The other end of the air spring is hinged on the car body. The upper end of a balance rod is hinged on the car body in the later edge adjacent to the door, and the lower end is hinged at the lower part of the later edge of the door.
Description
The utility model relates to vehicle accessory, the link door on specifically a kind of traveller's door that is used for vehicle or the rearmounted motor door.
The luggage door and the motor door of existing touring car, coach adopt " hinged door " mostly, this door utilizes hinge to be connected with doorframe, when opening or closing, door turns round around hinge, the defective of this door is that the space hold when opening is very big, if the vehicle automobile is parked in together side by side, spacing distance is quite near, and then the unlatching of hinged door is just relatively more difficult.Also once the someone has designed some Four-link doors, but because there is the problem in the design in this class Four-link door, the size of its tripping force, direction and position of action point design are improper, thereby when closing and opening, need very big power, simultaneously, easily fall after also existing unlatching, do not have coupling mechanism force when shutting, even send problems such as impact sound during running car.
The purpose of this utility model is a kind of Four-link door of opening conveniently, occupying little space when opening of design.
Its main technical schemes is respectively to connect a linkage in the both sides of door, in each linkage, there is the long arm end of a L shaped bar to be hinged in the middle part of the lateral margin of door, the galianconism end is on the car body that is hinged near the door side edge upper end, coupling block is arranged on galianconism, the expansion link outer end and the coupling block of air spring are hinged, the position of its pin joint C when door is in closed condition a little more than pin joint A on the L shaped bar galianconism end car body and the line of air spring between the pin joint B on the car body, and be positioned at the upper right side that A is ordered, other has an end of a balancing pole to be hinged on the lateral margin lower end of door, the other end is hinged on the car body near door side edge middle part, the pin joint E that balancing pole forms with door and car body respectively, distance between D equals or is approximately equal to the pin joint F that L shaped bar forms with door and car body respectively, distance between A.On car body, limited block is arranged, door lock also is installed on door near the door upper limb.
The utility model has the advantages that with common hinged door and compare, shortened activity space required when door opens and closes; Compare with general Four-link door, because the air spring of enabling gate acts on the position of the application point C on the door when door is in closed condition in the utility model, for a little more than the line between the pin joint B of the pin joint A of L shaped bar and car body and air spring and car body, and be positioned at the upper right side that A is ordered, when door is closed, air spring can produce an active force with door tension, makes the door of closing have the locking effect, not the closed condition of the vibration effect door that can produce because of vehicle '.When opening door, as long as door is pulled outwardly, L shaped bar is rotated around the A point, around being positioned at the AB line to the C point when following, door can be outwards own under the effect of air spring, moves up, make a unlatching, this moment, the C point moved to the C1 point, and F and E point move to F1 respectively, the E1 position, thereby in the whole opening process, only in that being moved to from the above position of AB line a bit of process of AB below connecting, the C point needs manpower, all the other processes all can utilize the power of air spring to finish, simultaneously because of C point a little more than the AB line, AC is apart from quite short, required manpower is fewer, thereby very laborsaving, secondly, because door utilizes quadric chain to be coupled to each other with car body, when door is opened or is closed, required rotary space is similar to A on the L shaped bar, D spacing, or D on the balancing pole, E spacing, this spacing are about half of door, that is requisite space is about former hinged door half, thereby reduced the space of being occupied when stopping.
Fig. 1 is a structure chart of the present utility model.
As shown in the figure, utilize two identical quadric chains that the couplet on the door is connected on the car body 7 respectively in the both sides of door 4.A L shaped bar 2 and balancing pole 3 are arranged in each quadric chain, and wherein, the long arm end of L shaped bar 2 is hinged on the lateral margin middle part of door 4, its pin joint is F, and the galianconism end is hinged near on the car body 7 on door side edge top, and its pin joint is A, the upper end of balancing pole 3 is hinged on the car body 7 near the middle part of door side edge, pin joint is D, and the lower end is hinged on the lower end of door side edge, forms pin joint E, wherein, the AF spacing equals or is approximately equal to the DE spacing, and the AD spacing equals or is approximately equal to F, E spacing.At the affixed coupling block 8 in the galianconism top of L shaped bar 2, the outer end of the expansion link 9 of air spring 1 is hinged on the top of coupling block 8, its pin joint is C, the other end of air spring is hinged on the car body 7, its pin joint is B, pin joint C wherein a little more than the line of pin joint A, B, and is positioned at the upper right side that A is ordered when door is in closed condition.Door lock 5 is installed at middle part at door 4, near the car body 7 of door upper limb limited block 6 is installed.
