Abstract
The invention relates to an open spring device of a cover plate of an engine. The open spring device comprises an upper plate of an open spring, a central shaft of the open spring, a lower plate of the open spring, a spring limit plate and the open spring. The open spring is arranged between the upper plate and the lower plate of the open spring, wherein one end of the open spring is tightly hooked on the upper plate of the open spring; and the other end of the open spring is clamped in a central hole of the central shaft of the open spring. The open spring device solves the problem that the cover plate of an engine room of an automobile is uneasy to open. The open spring device has a simple structure, space saving and small opening force and is suitable for the opening of the cover plateof the engineer of a commercial vehicle or a passenger car.
Description
Technical field
The present invention relates to a kind of opening spring mechanism of engine hood panel, in particular for the opening spring mechanism of commercial car or bus engine cover plate.
Background technology
For commercial car and passenger vehicle, owing to generally be arranged in the car by the limiting engine of moulding.At present the engine arrangement of existing this type of vehicle is near pilot set, and wherein the enging cabin left cover is arranged in below the driver's chair, and is very painstaking when therefore opening the enging cabin left cover and carrying out maintenance operation.In existing passenger car, hood and luggage compartment, perhaps also have same problem in the unlatching of back door, air spring is installed can well be addressed this problem, but at the situation of engine arrangement in car, its arrangement space is generally very limited, and design space, engine hood panel place is also very narrow and small, and the space of arranging air spring can't be provided.
Summary of the invention
The present invention has designed a kind of opening spring mechanism of engine hood panel, and it solves the stubborn problem of vehicle engine hatch cover plate.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme: a kind of opening spring mechanism of engine hood panel comprises and opens spring upper plate, unlatching spring center axle, unlatching spring lower plate, spring limiting board, unlatching spring.Described unlatching spring is installed between the spring upper and lower plates, wherein opens spring one end hook and is tightly opening on the spring upper plate, opens the spring other end and is stuck in the centre bore the inside of opening the spring center axle.
Also comprise and open spring arm B, an end of described unlatching spring center axle is connected with unlatching spring arm B by nut, and the other end is passed the spring lower plate and is connected with spring limiting board.
The opening spring mechanism of this engine hood panel has following beneficial effect with respect to prior art: this apparatus structure is simple, save the space, opening force is little, is applicable to the unlatching of commercial car or bus engine cover plate.Specifically: compare with air spring, this device overall dimensions is very little, in car, be easy to arrange, and engine hood panel can overturn after opening buckle 5 ° ± 2 ° automatically, open spring simultaneously a very big moment can be provided, when operating, people only need just can open engine hood panel, the central axis anglec of rotation 〉=85 ° in this device with very little power.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
Shown in Fig. 1 and Fig. 2, the present invention mainly is made up of unlatching spring upper plate 1, unlatching spring center axle 2, unlatching spring lower plate 3, spring limiting board 4, unlatching spring 5.Open spring 5 and be installed between the spring upper and lower plates 1,3, wherein open spring 5 one end hooks and tightly opening on the spring upper plate 1, open spring 5 other ends and be stuck in the centre bore the inside of opening spring center axle 2, the two ends of spring just have been fixed like this; Described unlatching spring 5 be the spiral shape torsionspring.An end of opening spring center axle 2 is connected with unlatching spring arm B by nut, and the other end is stretched out spring lower plate 3 and is connected with spring limiting board 4, and the other end of opening spring arm B links to each other with engine hood panel.The pointed portion of spring limiting board 4 snaps among the positive stop lug boss A of spring limiting board, plays position-limiting action.Engine hood panel overturns 5 ° ± 2 ° automatically when opening buckle, hand control is subsequently opened spring arm B and is driven and open springs 5 and do when being rotatablely moving of axle center with spring center axle 2 by opening spring center axle 2, spring limiting board 4 has just guaranteed to open the tram of spring center axle 2, has reached spacing purpose; The whole operation process has realized the unlatching of engine hood panel by the flexible and stopping means of opening spring.In addition, in the process of opening the spring arm motion,, realize opening the spacing of spring arm, finally realize safe and reliable purpose by opening positive stop lug boss C, the D of spring upper plate 1 self.
State when Fig. 4 is the hood plate closing, this moment, spring was in the maximum moment state of impulse stroke, worked as engine hood panel, comprise driver's chair, when rotating in opening process along the direction of arrow, the moment of spring slowly diminishes, and this moment is shown in figure five, engine hood panel, comprise driver's chair, the moment that is produced also slowly diminishes simultaneously, is opened to maximum rating until engine hood panel,, this moment is opposite with the moment direction of spring.
