Description
Technical field
The present invention relates to mover field, particularly relate to a kind of electrocar.
Background technology
Traditional mover design, is required to oil cylinder and acts between front/rear frame, and oil cylinder promotes vehicle frame, by
Vehicle frame pulls lower link, lower link passive rotation, thus promotes long connecting rod to play elevator to the level realizing vehicle frame
Dynamic.As number of patent application be 201110420520.4 patent names be that the Chinese invention patent of mover is this
Plant motion mode.This motion mode can make whole vehicle frame as beaer, thus the intensity to car load vehicle frame
Requiring higher, part manufacturing cost is high, and welding procedure is complicated, and welding precision requires high, and welding deformation
Then assembling is produced considerable influence, also is difficult to improve production efficiency simultaneously.
The vehicle frame top of tray truck all can be fixed with face shield, for protect install with vehicle frame in each zero
Parts, also make complete machine more attractive in appearance simultaneously.Face shield on tradition mover is generally individually bolted
On vehicle frame, when needing each parts in vehicle frame are overhauled, need to use tool ejector
Bolt, the most just can take face shield apart, and this unloading process is the most loaded down with trivial details, thus causing trouble gets rid of difficulty, dimension
Repair efficiency low, the after-sales service problems such as cost of labor is high.On the other hand, existing electrical equipment is generally individually to install
In vehicle frame, due to limited space in vehicle frame, so some electrical equipment can be only installed at below vehicle frame, so that
Must be more difficult to the maintenance of electrical equipment in vehicle frame.
Meanwhile, the first air spring on the handle mechanism in current logistics equipment industry is all disposed on handle tube
Inside, causes the first air spring narrow space, difficult arrangement, and it is high that parts make required precision, installs difficulty
Degree is big, and needs in handle tube by wire harness, does not the most note arising that the first air spring is the most crowded with wire harness
The problems such as pressure causes that wire harness is impaired, disconnects, short circuit, the most then cause vehicle trouble to use, heavy then cause
Cause security incident to lose control of one's vehicle, jeopardize operator and the life security of periphery workman.As Authorization Notice No. is
CN201049875Y, patent name be handle of fork truck the first air spring attachment means utility model patent and
Publication No. 104860231A, patent name is in the utility model patent handle mechanism of 104860231A

Embodiment 6
As shown in Figure 6, with embodiment 1 or 2, except that this electrocar also includes closed fork leg
Mechanism 4, fork leg mechanism 4 includes that fork leg body 401, fork leg body 401 include the main body that cross section is C-shaped
Part 402, also includes that reinforcing plate 403, reinforcing plate 403 are a monoblock elongated plates, and reinforcing plate 403 is with main
Body portion 402 is collectively configured to the fork leg body 401 that cross section is rectangle.
In the present embodiment, main part 402 is one-body molded with reinforcing plate 403, and i.e. fork leg body 401 part is i.e.
For the rectangular square tube structure that wall thickness is equal.Directly use this kind of rhs-structure, the production technology of pallet fork can be simplified,
Improving pallet fork production efficiency, the most integrated mode can make pallet fork overall structure more stable, structure
Intensity is more preferable.
According to maximum (normal) stressIt follows that the moment of inertia IXWith maximum (normal) stress
σmaxBe inversely proportional to, i.e. the moment of inertia is the biggest, more can meet requirement.
In formula: IXFor the moment of inertia, σmaxFor maximum (normal) stress, MmaxFor maximal bending moment, ymaxFor away from neutral axis
Maximum distance, [σ] is allowable stress.
Again by by formula the moment of inertiaDraw: the moment of inertia I of flat board fork platex1< close fork plate to be used to
Property square Ix2。
Wherein: gross area (the flat board fork plate gross area A of A---figure1< close fork plate gross area A2)；
ix---for cross section for the radius of inertia (radius of gyration) of x-axis.
I.e. the moment of inertia IXThe shape of concentrated expression cross section and the size impact on bending normal stresses.So
In the case of same material thickness, the fork leg of cross section shrouding is bigger than the fork leg the moment of inertia do not closed, identical
In the case of wall thickness, can carry more preferable than c-type structure, load-carrying is bigger.
Embodiment 7
As it is shown in fig. 7, with embodiment 6, except that reinforcing plate 403 and main part 402 are not one
Molding, but individually produce, finally originally it is welded on strengthening at the c-shaped opening of main part 402, i.e. exists
Weld one block of plate in the fork leg of C-shaped cross section, make fork leg cross section can form all round closure formula structure.In like manner, use
This kind of mode also can make in the case of identical wall thickness, reaches the ratio c-type more preferable bearing capacity of fork leg structure,
Load-carrying is bigger.
Embodiment 8

404, through hole 404 is evenly arranged along pallet fork length direction, by opening in reinforcing plate 403 in the present embodiment
If through hole 404, while increasing pallet fork bearing capacity, also allow for being sprayed paint in pallet fork inside.
By being stretched in hole by spray gun in painting process, and then can complete to be sprayed paint in pallet fork inside, have
Effect prevents pallet fork internal corrosion, increases pallet fork service life.
Embodiment 9
As it is shown in figure 9, with embodiment 6 or 7, except that reinforcing plate 403 is polylith horizontal stripe plate 405,
Distance between adjacent two blocks of horizontal stripe plates 405 is equal.By design polylith horizontal stripe plate 405 in the present embodiment,
While increasing pallet fork bearing capacity, also allow for being sprayed paint in pallet fork inside.
Spray gun is extend in pallet fork by painting process by the spacing between horizontal stripe plate 405, and then can be complete
Spray paint inside pallet fork in pairs, effectively prevent pallet fork internal corrosion, increase pallet fork service life.
Embodiment 10
Such as Figure 10, shown in 11, with embodiment 1 or 2, except that this electrocar also includes handle
Mechanism 5, handle mechanism 5 includes handle mount 501, handle mount 501 is provided with handle joint 502,
Being connected by handle tube 503 in handle joint 502 has handle head 504, handle joint 502 to be provided with circle
Installing hole, the cross section of handle tube 503 is circular, in inserting installing hole and is fixed by screw bottom it.
Handle tube 503 is used bayonet joint at handle joint 502, and can fix with a screw,
Make it install, when dismantling, the most only need to install or remove a screw, be greatly reduced handling steps with difficult
Degree.
Simultaneously when transport packing, it is to avoid original handle head 504 of only dismantling, handle tube 503 is still erected at
On vehicle body, so that packing is highly higher than the situation of height of the carbody, can be by handle tube in the present embodiment
503 also dismantle, and only leave handle joint 502 so that packing is highly height of the carbody, reduces transport case
Height, reduce packing charges, considerably reduce freight.
