It is L-shaped to rotate corner fittings 4, is bonded with bumper beam 3 and offers bolt apertures (being blocked by bolt/nut, be not shown) on one side, with
The fitting of bumper column 2 offers the first axle center hole 31 and the first rotation hole 32 in its longitudinal direction on one side；The bumper
Column 2 offers second axle center hole corresponding with the first axle center hole 31 in vertical direction, and (it is hidden by the first axle center hole 31 always
Gear, is not shown) and the second rotation hole 21；The setting of bumper support part 5 is in bumper column 2 and flange protrusion is protected
Dangerous thick stick column 2, offers third rotation hole 53 in the horizontal direction；First rotation hole 32, the second rotation hole 21, third
Rotation hole 23 is identical as the distance between 31/ second axle center hole of the first axle center hole；The rotary pin shaft 6 has two in unilateral side, and one
In the first axle center hole 31 and the second axle center hole corresponding position, another is arranged in the first rotation hole 32 for root (always) setting, and
It is locked by bending part；The bumper beam 3 is bonded side with rotation corner fittings 4 and offers T-slot 33；The T-slot
33 positions are corresponding with bolt apertures and are locked by bolt/nut 34 and rotation corner fittings 4.
As shown in Fig. 1~5, the present embodiment is in unfolded state, when being used as protective device, bumper beam 3 and insurance
Thick stick column 2 is parallel.Fig. 5 is referred to, the first axle center hole 31 and the second axle center hole are corresponding always, at this time the first rotation hole 32 and second turn
Dynamic 21 position of hole corresponds to, and wears rotary pin shaft 6 in corresponding points at two, is fixed by bending part, is completed rotation corner fittings 4 with this and is protected
The connection of dangerous thick stick column 2.Note that having no rotary pin shaft 6 in third rotation hole 53 at this time.
Then complete with this by the way that bolt/nut 34 is clamped connection by rotating the bolt apertures on corner fittings 4 and T-slot 33
At the connection of rotation corner fittings 4 and bumper beam 3.
As shown in Fig. 6~11, the present embodiment is in folded state, and disassembly process is：The first rotation hole 32/ second will be located at
The bending part of 21 corresponding position of rotation hole removes, and takes out the rotary pin shaft 6 in it, rotation corner fittings 4 is rotated by 90 °, until first
Rotation hole 32 is directed at third rotation hole 53, and the rotary pin shaft 6 removed is worn into 32/ third rotation hole 53 of the first rotation hole,
It such as Fig. 8, is fixed again by bending part, completes the connection of rotation corner fittings 4 and bumper column 2, and then complete rear
Folding.Note that having no rotary pin shaft 6 in the second rotation hole 21 at this time.
So far, the present embodiment is converted into step realizing rear by installing switching mechanism additional when needed makes
With facilitating vehicle, vehicle, raising handling goods efficiency realize two kinds of purposes of a device above and below personnel in handling goods.
Further, 31/ second axle center hole of the first axle center hole, the second rotation hole 21 of the present embodiment use, third rotation
Casing 7 is respectively equipped in hole 53；The rotary pin shaft 6 is rotatably set in casing 7, such as Fig. 5,8；Casing 7 can guarantee overturning
The reliable location of rotary pin shaft 6 in the process ensures concentricity.
Further, the bumper beam 3 that the present embodiment uses is anti-equipped at least two groups first in the opposite face of T-slot 33
Sliding fin 35, as step in use, the first antislip cog 35 improves 3 end face of bumper beam after protective device folding
Skid resistance improves safety coefficient when handling goods personnel or more vehicle；In 3 parallel bumper column 2 of bumper beam,
It is equipped with the second antislip cog 36 towards 1 one side of bumper roof side rail, when protective device is unfolded, vehicle operator can pass through
This end face is got on or off the bus, and the antiskid effect of the end face has can be improved in the second antislip cog 36.
Further, the present embodiment further includes the support plate 51 and diagonal brace 52 that connection is arranged in bumper support part 5；It is described
51 vertical bumper support part 5 of support plate is arranged；52 one end of the diagonal brace is connected to support plate 51, and the other end is connected to bumper support
Part 5, and its surface offers the through-hole (sleeve 7 is blocked, and is not shown in figure) passed through for casing 7, which can share rotation
The tangential stress at 7 middle part of axis pin 6 and casing, ensures its structural strength, keeps it not pliable or be broken.
Further, abrasion-proof rubber cushion is equipped between the bumper beam 3 that the present embodiment uses and rotation 4 binding face of corner fittings
Plate 8 can prevent from rubbing caused by the gap in driving conditions between bumper beam 3 and bumper column 2 and touch such as Figure 10,11
It hits and sends out abnormal sound.
Further, the bending for the rotary pin shaft 6 being located in 31/ second axle center hole of first axle heart hole is locked in the present embodiment
Part is split pin 61, such as Figure 12, because the rotary pin shaft 6 in 31/ second axle center hole of the first axle center hole does not need in use
Extraction, using split pin 61 to it with better locking effect.
Further, in the present embodiment locking positioned at the second rotation hole 21 or the rotary pin shaft 6 in third rotation hole 53
Bending part is R types pin 62, such as Figure 12, because the rotary pin shaft 6 in the second rotation hole 21 or third rotation hole 53 is understood according to using feelings
Condition dismounting extraction, using R types pin 62 it is conveniently detachable and locking.
Further, the bumper beam 3 that the present embodiment uses is equipped with end cap 37 in its both sides, and such as Fig. 4, comparison diagram 9 is not
State with end cap 37, the design of end cap 37 can avoid 3 inside of bumper beam and enter impurity, imitated with good sealing
Fruit.
Excellent further, bumper roof side rail 1, bumper column 2 and the bumper beam 3 that the present embodiment uses use aluminium
Alloy material is made, which can be greatly reduced the weight of rear, and makes it have corrosion resistant design feature.
Further, if being offered on bumper roof side rail 1, bumper support part 5 and diagonal brace 52 that the present embodiment uses
Dry lightening hole 9, the design can further decrease the weight of rear.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
