The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
As shown in Figure 1-3, the embodiment of the present invention provides a kind of cargo box sideboard power assisting device, the cargo box sideboard power assisting device
Include:
The horizontal support arm of force 3 being rotatablely connected with the outside of side plate 1；
The perpendicular support arm of force 4, first end are connect with the horizontal support arm of force 3, floor side frame 2 side of the second end to 1 lower section of side plate
It offsets to extension, and with floor side frame 2；
Return spring 5, the return spring 5 is contacted with the perpendicular support arm of force 4, when side plate 1 is opened, the return spring 5
For providing the active force towards side plate 1 to the perpendicular support arm of force 4.
Wherein, there are many set-up modes of return spring 5, specifically with no restriction, as long as can be realized to perpendicular support force
Arm 4 provides the active force towards side plate 1, to act on 3 generation of the horizontal support arm of force, the horizontal support arm of force 3 is made to squeeze side plate 1, right
The unlatching of side plate 1 generates reaction force, can offset the gravity of part or all of side plate 1, consequently facilitating operator opens and closes side
Plate 1；
Specifically, in the present embodiment, preferably, two fixing seats 6 at 3 both ends of the horizontal support arm of force are set, it is described solid
Reservation 6 is fixed on 1 outer surface of side plate, fixing seat 6 and 3 end axis connection of the horizontal support arm of force.
Wherein, the return spring 5 of the present embodiment is wrapped on the horizontal support arm of force 3, passes through 1 outside table of retention bead and side plate
Both faces provide torsion, so that providing the active force towards side plate 1 to the perpendicular support arm of force 4, i.e., to the horizontal support arm of force 3 with respect to side plate
1 rotation provides certain resistance, and the horizontal support arm of force 3 is made to squeeze side plate 1, generates reaction force to the unlatching of side plate 1；Specifically, make
To be preferred, it is provided with stopper protrusion 41 on the perpendicular support arm of force 4, the return spring 5 is wrapped on the horizontal support arm of force 3, and one
End offsets with 1 outer surface of side plate, and the other end offsets with stopper protrusion 41.
And in another embodiment, preferably, 5 one end of the return spring and 1 outer surface of side plate or floor side frame 2
Connection, the other end are connect with the perpendicular support arm of force 4.It so can be achieved to provide the perpendicular support arm of force 4 pulling force, it is same to realize to perpendicular support
The arm of force 4 provides the active force towards side plate 1, realizes corresponding function.
Cargo box sideboard power assisting device provided by the invention, by the way that the return spring 5 contacted with the perpendicular support arm of force 4 is arranged, when
When side plate 1 is opened, return spring 5 is used to provide the perpendicular support arm of force 4 active force towards side plate 1, that is, slows down the perpendicular support arm of force 4
Far from side plate 1, to act on 3 generation of the horizontal support arm of force, the horizontal support arm of force 3 is made to squeeze side plate 1, the unlatching of side plate 1 is generated
Reaction force can offset the gravity of part or all of side plate 1, consequently facilitating operator opens and closes side plate 1；Structure of the invention letter
It is single, it is easy to operate.
Preferably, the horizontal support arm of force 3 is parallel with the length direction of side plate 1, and the perpendicular support arm of force 4 and horizontal support power
Arm 3 vertically connects.
Preferably, the perpendicular support arm of force 4 is provided with idler wheel 7, the idler wheel 7 and ground with 2 place of offseting of floor side frame
Plate side frame 2 connects, and the perpendicular support arm of force 4 can be slided along idler wheel 7.Preferably, the idler wheel 7 is fixed by mounting base 8
On floor side frame 2.
Specifically, 5 sets of return spring on the horizontal support arm of force 3, one end resists cargo box sideboard 1, and the other end resists limit convex
Portion 41, so that the perpendicular support arm of force 4 is close to floor side frame 2, bottom is pressed on idler wheel 7.When side plate 1 is in close state
When, it is parallel with side plate 1 to erect the support arm of force 4；When side plate 1 is opened, the perpendicular support arm of force 4 then generates angle between side plate 1, i.e., around
Upper lateral supports the arm of force 3 to rotate, and tightens return spring 5, since idler wheel 7 limits the rotation of perpendicular support 4 bottom of the arm of force, in return bullet
Under the reaction force of spring 5, the horizontal support arm of force 3 squeezes side plate 1, and active force is generated to it, offsets the part gravity of side plate 1, forces
It is closed.
Idler wheel 7 is cylinder, is mounted on the side frame on container floor by 7 mounting base 8 of idler wheel；
Source of the present invention and pickup truck tailgate container, it is intended to apply to automotive field, realize that reducing cargo box sideboard 1 opens and closes
When manual operation power purpose, but be also not limited to automotive field, the present invention also can operate with other productions and life
It is middle to need to realize the occasion for reducing operating force, such as all kinds of doors or cover board；Intention of the invention is to utilize torsion return spring 5
Reaction force and lever principle offset the gravity of part cargo box sideboard 1, to reverse two free ends point of return spring 5
It is not impetus with the horizontal support arm of force 3 and 1 lap position of cargo box sideboard, however not excluded that by the position or the benefit that change return spring 5
It is realized with simple and mechanical principle to stretch or the sub-assemblies of compression retracteding position spring 5 and other components substitutes torsion return
Spring 5 even substitutes spring using other elastic elements or device to realize the mechanism of identical function, thus reach with
The identical purpose of the present invention.
