A kind of enging cabin cover opening mechanism
Technical field
The utility model relates to vehicle structure, and more particularly, the utility model relates to a kind of vehicle engine hatch cover opening mechanism.
Background technology
At present, similar car load product forward engine room cover opening mechanism does not adopt mechanically aided device at some, the mode that the cabin lid is opened the whole process using manpower, because cabin cover tape annex assembly gross weight is about 20 kilograms, when the lid standard-sized sheet of cabin, its opening angle is about 60 °, the general maximum of manpower is about 20 (kilogram) * 10 (newton/kilogram) * COS60 ° ÷ 2=86.6 (newton) like this, the maximum height of lifting is about 1.8 meters, comprehensive these situations are reached a conclusion, the opening device human engineering that does not have mechanical power-assisted is poor, is inconvenient to use.
Though there are some similar car load products to adopt mechanically aided enging cabin cover opening mechanism, engine casing support, the patent No. that as the patent No. is 01137296.6 spring-loaded is that 02802321.8 opening device, the patent No. are a kind of device on 87106191 the spring brake starter, all do not have fine the addressing this problem of energy, still exist and use inconvenience, make defectives such as difficulty.
The utility model content
Problem to be solved in the utility model provides a kind of enging cabin cover opening mechanism, its objective is that the unlatching closure that makes engine compartment cover is convenient.
To achieve these goals, the technical scheme that the utility model is taked provides a kind of enging cabin cover opening mechanism, be located in the enging cabin body and connect engine compartment cover and chassis runner, described enging cabin cover opening mechanism is made as air spring, the cylinder body of the air spring piston rod on the air spring connects with chassis runner, and the air spring piston rod on the air spring connects with engine compartment cover.
When described air spring was in the He Gai position at engine compartment cover, described air spring was a horizontal level, and the air spring piston rod is in the extreme position in the indentation air spring piston rod.
The cylinder body of described air spring piston rod and chassis runner draw bail be for establishing the air spring mounting bracket fastening with it on chassis runner, shipping and reselling on another market by the piston rod connecting pin with air spring mounting bracket connection place in the outer end of the cylinder body of air spring piston rod connects; Described air spring piston rod and engine compartment cover draw bail are shipped and resell on another market and are connected for establish the piston rod connecting pin in the outer end of air spring piston rod and the connection place of engine compartment cover.
Adopt technique scheme compared with prior art, the utility model is the mechanically aided device of Pneumatic spring type, optimized the opening mechanism structure Design, simple in structure, make engine compartment cover open and closed easy to operate, laborsaving, human engineering is strong, alleviates user's manipulation strength, and cost is also lower simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Accompanying drawing is a structural representation of the present utility model.
Number in the figure is: 1, piston rod connecting pin, 2, the air spring piston rod, 3, engine compartment cover, 4, the air spring piston rod, 5, the piston rod connecting pin, 6, the enging cabin body, 7, the air spring mounting bracket, 8, air spring, 9, chassis runner.
The specific embodiment
Shown in the expressed structural representation of the present utility model of accompanying drawing, the utility model is a kind of enging cabin cover opening mechanism, be located in the enging cabin body 6 and connect engine compartment cover 3 and chassis runner 9, its effect is to play power-assisted when engine compartment cover 3 is opened.
The purpose of this utility model is to make the unlatching closure of engine compartment cover convenient, therefore the technical scheme of being taked is that the enging cabin cover opening mechanism is made as air spring 8, the cylinder body of the air spring piston rod 4 on the air spring 8 connects with chassis runner 9, and the air spring piston rod 2 on the air spring 8 connects with engine compartment cover 3.
When air spring 8 was in the He Gai position at engine compartment cover 3, described air spring 8 was a horizontal level, and air spring piston rod 2 is in the extreme position of 4 li of indentation air spring piston rods.
The cylinder body of air spring piston rod 4 and chassis runner 9 draw bails are for establishing piston rod connecting pin 5, both are the connection of shipping and reselling on another market in the outer end of the cylinder body of air spring piston rod 4, the lower end bulb of air spring piston rod 4 is that piston rod connecting pin 5 is connected on the air spring mounting bracket 7 by ball stud, and air spring mounting bracket 7 is installed on chassis runner 9 panel beatings; Air spring piston rod 2 and engine compartment cover 3 draw bails are for establishing piston rod connecting pin 1, and both are the connection of shipping and reselling on another market in the outer end of air spring piston rod 2.The upper end bulb of air spring piston rod 2 is connected on the engine compartment cover 3 inboard panel beatings by ball stud.
Engine compartment cover 3 is untied the cabin cover lock when complete make position, manpower holds up engine compartment cover 3 and reaches certain altitude (about 200 millimeters), and this moment, the gravity of engine compartment cover 3 assemblies was in equilibrium state with the elastic force of air spring 8, and the operator can not add external force at this moment; Utilize the speed inertia of first step lifting, engine compartment cover 3 will raise distance greater than 200 millimeters, this moment, the lifting force of air spring 8 will be greater than the gravity of engine compartment cover 3, and engine compartment cover 3 continues to rise and causes the maximum lift of air spring 8, and engine compartment cover 3 is opened fully; Shutoff operation is opposite with said process.
The application of force of manpower distance has only 200 millimeters in the opening process of whole engine compartment cover 3, and common place of application of force is at the following position of the underbelly of human body under this state, and human body can apply active force easily to external world, thereby reaches the labour-saving purpose.
The people is positioned at people's position, the crown to the application point of engine compartment cover 3 during shutoff operation, and human body can utilize the gravity of self that engine compartment cover 3 is applied active force like this, thereby demonstrates fully human engineering, reaches simple to operate, light purpose.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
