Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of front hatchcover of the invention, as shown in Figure 1 and Figure 2, front hatchcover, including left and right are arranged side by side
And one end passes through the movable rocker arm 2 and hold-down support 1 that swivel pin 3 is hinged, movable rocker arm 2 and fixed branch at articulated position
Gasket 5 is equipped between seat 1, movable rocker arm 2 is connect with front hatch cover, hold-down support 1 is connect with front deck cabin, and hold-down support 1 is at it
The through-hole 111 that the lower section of articulated position is equipped with for reducing 1 crumple intensity of hold-down support, movable rocker arm 2 is far from articulated position
One end is equipped with the bar 22 to overhang towards hold-down support 1, and hold-down support 1 is equipped with Stop structure corresponding with bar 22, block
Structure has for cooperating to prevent with 22 block of bar after the direction crumple deformation towards articulated position in movable rocker arm 2
The stopping surface 12 that front hatch cover on movable rocker arm excessively moves backward.
In the present embodiment, the projecting end of bar 22 is equipped with the tongue 21 to bending at articulated position, sets on stopping surface 12
There is the slot 13 corresponding with tongue 21 on the direction that movable rocker arm 2 extends, slot 13 is in movable rocker arm 2 along towards articulated position
Direction crumple deformation after with 21 grafting of tongue to limit tongue 21, bar 22, movable rocker arm 2 and be fixed on movable rocker arm
The movement of front hatch cover on 2, therefore front hatch cover can be prevented to be opened and cause damages in an impact；Specifically, Stop structure
Including the one end of hold-down support 1 far from articulated position, bending part with U-shaped groove, the opening direction of U-shaped groove is arranged in
To the right away from the installation position of movable rocker arm 2 and corresponding front deck, bending part constitutes above-mentioned stopping surface far from the end face of articulated position
12, U-shaped groove installation position corresponding with front deck collectively forms above-mentioned slot 13.
In other embodiments, bending part can also be replaced with reeded block is set on end face, and groove is as slot 13
It uses；Slot 13 can also individually limit the movement of tongue 21 on left and right or up and down direction.
In the present embodiment, for the ease of processing and manufacturing, bending part and the integrated bending punch forming of hold-down support 1, therefore
Bending part and hold-down support 1 belong to one, and bending part becomes the bending part of hold-down support 1.In other embodiments, bending part
It can be separately fabricated and be welded on hold-down support 1.
In the present embodiment, it is used to reinforce the convex of the structural strength of the bending part on the upper side wall of bending part there are two setting
Play structure 14；The bolt hole for being fixed on bending part in front deck cabin is equipped on upper side wall and lower wall.In other realities
It applies in example, bulge-structure 14 can also be also provided in lower wall to reinforce intensity；It can also be at other positions of hold-down support 1
Setting installation fixed point.
Hold-down support 1 is equipped with the baffle 11 for limiting the height that movable rocker arm 2 is rotated up, to prevent front hatch cover
It is excessively overturn in maintenance, baffle 11 is equipped with for buffering movable rocker arm 2 to the cushion of the impact force of baffle 11, baffle 11
On be additionally provided with reinforcing rib 15 for reinforcing its structural strength.
Movable rocker arm 2 is arc, consequently facilitating crumple when being collided.
The tongue 21 of bar 22 in slot 13 along the vertical direction on active length not less than the through-hole on hold-down support 1
111 crumple length, so that tongue 21 still is able to corresponding and is inserted into slot 13 after 111 crumple of through-hole.
Specifically when installing and using, hold-down support 1 is fixed on front deck by bending part or bending part, while by front hatch cover
It is connected on movable rocker arm 2.When needing to open front hatch cover, front hatch cover is pulled to rotate movable rocker arm 2 around swivel pin 3
, it is excessive that the baffle 11 on hold-down support 1 can prevent front hatch cover from opening amplitude.
When colliding, the through-hole 111 of hold-down support 1 can undertake a degree of crumple, arc in up and down direction
Movable rocker arm 2 can bear a degree of crumple on front-rear direction, after crumple occurs for movable rocker arm 2, bar 22 is to gear
Only face 12 moves, until stopping surface 12 stops bar 22, to make front hatch cover no longer to the direction of articulated position i.e. cockpit institute
Direction move, avoid front hatch cover and be excessively entering into cockpit and cause damages to occupant, meanwhile, the tongue 21 of bar 22 is inserted into
In slot 13, slot 13 can be in upper and lower, limitation tongue 21 on left and right directions activity, to limit bar 22, movable rocker arm 2
And front hatch cover is in activity upper and lower, on left and right directions, and then reach prevent front hatch cover because opened in collision to occupant with hit
The case where person causes damages.In addition, the present invention can be integrally formed punching press bending manufacture, component is few, light-weight, Maintenance and Repair letter
It is single, it is practical.
Including vehicle frame, the front deck of the vehicle frame front is arranged in and by front hatchcover and the front deck in vehicle
The front hatch cover of cabin connection, a kind of front hatchcover front hatchcover as described above, so it will not be repeated.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
