Abstract

The utility model relates to an automobile engine compartment cover hinge for hinging an automobile engine compartment cover with an engine compartment rack, which comprises a fixed hinge plate and a rotating hinge plate, wherein a vertical plate in the fixed hinge plate consists of a first step surface, a second step surface, a third step surface, a first inclined surface and a second inclined surface, and the first step surface is positioned around a hinging hole and is jointed with a hinging plate of the fixed hinge plate; and the second step surface and the third step surface are arranged at a distance from the hinging plate, and the distance between the second step surface and the hinging plate is smaller than the distance between the third step surface and the hinging plate. The hinge has sufficient rigidity and simpler molding process.

Description

Automobile engine nacelle cover hinge

Technical field

The utility model relates to a kind of auto parts and components, especially for automobile engine nacelle cover and enging cabin frame are carried out hinged articulated mounting.

Background technology

The automobile engine nacelle cover is to be installed on the enging cabin frame by enging cabin cover hinge, enging cabin cover hinge is by fixed leaf plate and change that moveable leaf plate is hinged to form, fixed leaf plate is installed on the hinge installing plate on the enging cabin frame, change moveable leaf plate and then be installed on the automobile engine nacelle cover, change moveable leaf plate and rotate the opening and closing that can realize the enging cabin cover around the swivel pin axis.

As shown in Figure 3, fixed leaf plate has the riser 6 that offers hinge hole, change moveable leaf plate and have the articulated slab 8 that offers hinge hole, riser 6 by joint pin 9 and articulated slab 8 hinged after, riser and articulated slab fit.

Fixed leaf plate and commentaries on classics moveable leaf plate all are stamping forming sheet metal components, for the reliability that guarantees that the enging cabin cover is connected with the enging cabin frame, just must guarantee that enging cabin cover hinge has enough rigidity, for this reason, existing enging cabin cover hinge fixed leaf plate 3 is provided with reinforcing rib 13,14,15,16,17, these reinforcing ribs are complex-shaped, cause the moulding process of hinge poor, and hinge makes that required mould structure complexity, materials are many, difficulty of processing is big, processing cost is high.

The utility model content

The purpose of this utility model provides a kind of automobile engine nacelle cover hinge, guaranteeing that hinge has under the prerequisite of enough rigidity, the moulding process of hinge is improved.

Automobile engine nacelle cover hinge described in the utility model comprises fixed leaf plate and changes moveable leaf plate, fixed leaf plate has the riser that offers hinge hole, change moveable leaf plate and have the articulated slab that offers hinge hole, riser is hinged by joint pin and articulated slab, riser is by first, second, the 3rd step surface and first, second inclined-plane constitutes, the first step face is positioned at around the hinge hole, fit with the articulated slab that changes moveable leaf plate, second, the 3rd step surface and the articulated slab distance of being separated by, and the distance between second step face and the articulated slab is less than the distance between the 3rd step surface and the articulated slab, connect by first inclined-plane between first step face and the second step face, connect by second inclined-plane between second step face and the 3rd step surface.

On the 3rd step surface of the riser of fixed leaf plate, offer through hole, both can guarantee that hinge has certain collision crumple, has reduced the weight of hinge again.

Hinge described in the utility model is because its fixed leaf plate has this staircase structural model, and the same technique effect with enhancing fixed leaf plate rigidity with reinforcing rib of this kind structure has enough rigidity so can guarantee hinge; And the moulding process of this kind staircase structural model is comparatively simple, thereby has reduced the die needed complex structure degree of hinge moulding, makes that the mould materials being fabricated is few, difficulty of processing and processing cost be minimized.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 looks schematic diagram for the master of automobile engine nacelle cover hinge described in the utility model;

Fig. 2 is the schematic perspective view of fixed leaf plate;

Fig. 3 looks schematic diagram for the master of existing automobile engine nacelle cover hinge.

The specific embodiment

As depicted in figs. 1 and 2, this automobile engine nacelle cover hinge is made up of fixed leaf plate 3 and commentaries on classics moveable leaf plate 1, fixed leaf plate 3 has the riser 6 that offers hinge hole 12, change moveable leaf plate 1 and have the articulated slab 8 that offers hinge hole, riser 6 is hinged by joint pin 9 and articulated slab 8, thereby makes fixed leaf plate 3 hinged with rotation page or leaf 1 plate.

Riser 6 is made of first step face 7, second step face 11, the 3rd step surface 5 and first inclined-plane 10, second inclined-plane 2, and first step face 7 is positioned at around the hinge hole 12, fits with the articulated slab 8 that changes moveable leaf plate 1; Second,

third step surface

11,5 and articulated slab 8 distance of being separated by, and the distance between second step face 11 and the articulated slab 8 is less than the distance between the 3rd step surface 5 and the articulated slab 8; Connect by first inclined-plane 10 between first step face 7 and the second step face 11, connect by second inclined-plane 2 between second step face 11 and the 3rd step surface 5, on the 3rd step surface 5 of riser 6, offer through hole 4.

Claims

1. automobile engine nacelle cover hinge, comprise fixed leaf plate (3) and change moveable leaf plate (1), fixed leaf plate has the riser (6) that offers hinge hole (12), change moveable leaf plate and have the articulated slab (8) that offers hinge hole, riser is hinged by joint pin (9) and articulated slab, it is characterized in that: riser is by first, second, the 3rd step surface (7,11,5) and first, second inclined-plane (10,2) constitute, the first step face is positioned at around the hinge hole, fit with the articulated slab that changes moveable leaf plate, second, the 3rd step surface and the articulated slab distance of being separated by, and the distance between second step face and the articulated slab is less than the distance between the 3rd step surface and the articulated slab, connect by first inclined-plane (10) between first step face (7) and the second step face (11), connect by second inclined-plane (2) between second step face (11) and the 3rd step surface (5).
