Specific embodiment
Below by way of specific embodiment, the invention will be further described.
Referring to figs. 1 to Figure 14, a kind of armrest linkage mechanism is installed between handrail 60 and battery cover 70, and battery cover 70 is set
There is hinged set 71, the hinged set 71 and vehicle frame battery case corresponding position are hinged, and battery cover 70 can be steered to be rotated in fact around articulated shaft
Now open or close.Mechanism of the invention has specifically included driving member 10, traction rope 20, rotating turret 30, casing 21 and bracket 40
Deng.The driving member 10 is equipped with two connecting plates 11 and first rotating shaft 12, which is fixedly connected on two connecting plates, 11 one end, this
The hinged set 71 of one shaft 12 and battery cover 70 is rotation connection, and the first rotating shaft 12 is set for the eccentric, i.e., not with articulated shaft
On the same axis.When battery cover 70 opens or closes, 10 eccentric rotary of driving member.
Further, which offers sliding slot 72, and the sliding slot 72 is vertical with articulated shaft, and first turn of driving member 10
Axis 12 is to be slidably matched with the sliding slot 72.
Seat 80 is installed in battery cover 70, and bracket 40 is fixed on 80 side of seat and is equipped with the second shaft 41, limit plate
42 and fixed plate 43 etc., second shaft 41 are vertically installed in 40 side of bracket, and it is another which is vertically installed in bracket 40
Side is close to 70 position of battery cover.The fixed plate 43 offers bayonet 44.The limit plate 42 is perpendicularly fixed at bracket 40 bottom of close to
Portion position, the limit plate 42 are additionally provided with the first confined planes 45 and the second confined planes 46, which is located at limit plate 42
Top surface, second confined planes 46 are located at 42 side of limit plate and perpendicular with the first confined planes 45.
The rotating turret 30 is fixed on 60 side of handrail and opposite with bracket 40, is equipped with axle sleeve 31 and connecting shaft 32.The axis
Set 31 is sheathed on rotationally connected in the second shaft 41 of bracket 40.The connecting shaft 32 is perpendicularly fixed at rotating turret 30 close to top
Portion position, and it is located at opposite 40 side of bracket.30 relative limit plate of rotating turret, 42 side is correspondingly provided with the first block face 33 and
Two block faces 34, the first block face 33 are located above the second block face.When handrail 60 is unfolded, second block face 34 and the second confined planes 46
Near or against contact.When handrail 60 is packed up, which is resisted against on the first confined planes 45.The limit plate 42 is used for
The angle (such as 65 °) that rotating turret 30 rotates is limited, can also change rotational angle by adjusting the position of limit plate 42.
The fixation of 21 one end of casing is arranged on the bayonet 44 of fixed plate 43.70 bottom surface of battery cover is set close to 71 position of hinged set
There is supporting plate 73,21 other end of casing fixation is arranged on the supporting plate 73.Two companies of driving member 10 are fixed in 20 one end of traction rope
11 other end of plate, 20 other end of traction rope pass through casing 21 and are fixedly connected with the connecting shaft 32 of rotating turret 30.Traction rope 20 is close
End position is additionally provided with limited block 22 to limit traction rope 20.When 12 eccentric rotary of first rotating shaft, which, which drives, turns
The rotation of moving frame 30 realizes that handrail 60 is packed up or is unfolded.
It further, further include flexible part 50, which is gas spring, and one end is fixed on bracket 40 close to top
Portion position, the other end are fixed in connecting shaft 32.When rotating turret 30 rotates, plays power-assisted and stablize pressuring action, prevent vehicle
The case where shake and handrail 60 occurred in driving process is fallen after packing up.
The present invention also proposes a kind of fork truck, including seat 80, battery cover 70 and vehicle frame etc..The seat 80 is installed on battery cover
On 70, which is equipped with hinged set 71, and the hinged set 71 and the battery case corresponding position of vehicle frame are hinged.On further including
A kind of armrest linkage mechanism stated.
The working principle of armrest linkage mechanism and fork truck of the invention is as follows, referring to Fig.1 1- Figure 14, sets 72 one end of sliding slot
For B, 72 other end of sliding slot is P, and position is D, middle position E, target position F when battery cover 70 is closed；Fixed plate 43 is blocked
The position of the second shaft 41 is H when mouthful 44 positions are 70 closed position of battery cover K, and the position of the second shaft 41 is when middle position
I。
Original state: battery cover 70 is closed and handrail 60 is unfolded, and first rotating shaft 12 is located at 72 one end of sliding slot, rotating turret 30
For second block face 34 with the second confined planes 46 of limit plate 42 near or against contacting, elastic component 50 is in tensional state, BD and BP
Between angle be obtuse angle.
Handrail is packed up: manual operation handrail 60 turns over, then rotating turret 30 rotates up to rotating turret 30 the around the second shaft 41
One block face 33 is resisted against on the first confined planes 45, then handrail 60 is packed up.
Battery cover is opened: manual operation battery cover 70 turns over, and the first rotating shaft 12 of driving member 10 and hinged eccentric shaft then pass
10 eccentric rotary of moving part pulls traction rope 20, and traction rope 20 pulls connecting shaft 32 that rotating turret 30 is rotated around the second shaft 41,
When battery cover 70 turns over arrival close to middle position E (40 degree of positions), the first confined planes 45 are resisted against on the second block face 34, are helped
Hand 60 is packed up, and elastic component 50 crosses shortest route from tensional state and reaches tensional state；Battery cover 70 continues to turn over arrival target
Position F (85 ° of positions), because the angle between BE and BP is at an acute angle, then the first rotating shaft 12 of driving member 10 72 is moved to along the chute
The other end avoids traction rope 20 from pulling on handrail 60, and during this, PF and BE length variation avoid continuing within 10mm
Pull handrail 60.In whole process, BD+KH=BE+KI+10=PF+KI, traction rope 20 is required to pull stroke for 50mm or so,
For tightening force in 600N or so, track length is 45mm or so.70 closing process of battery cover is opposite with opening procedure sequence.
The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited to this, all to utilize this
Design makes a non-material change to the present invention, and should all belong to behavior that violates the scope of protection of the present invention.
