Friction force between 10.
Referring to Figure 1 and Fig. 3, in the present embodiment, the hinge lugs 81 and pair that master slider 6 and master connecting-rod 3 are hinged and connected are sliding
The hinge lugs 81 that block 8 is hinged and connected with slave connecting rod 4 are in the vertical direction to mutually stagger, since compartment side door plate 2 is to compartment 1
When inside swings and is closed compartment 1, master connecting-rod 3 and slave connecting rod 4 can be close to each other, by upper and lower two hinge lugs 81 perpendicular
Histogram prevents master connecting-rod 3 and slave connecting rod 4 from interfering after folding or generating internal stress and influences the two normally to being arranged in a staggered manner
Work.
Referring to Figure 1 to Fig. 4, the working principle of hydraulic motor vehicle door arrangement is opened in the utility model embodiment logistics vehicles side are as follows:
When solenoid directional control valve 18 is in middle position, the hydraulic oil in fuel tank 22 is delivered up by oil pump 12, hydraulic oil
It by the first check valve 13 and hand-operated direction valve 17 and flows into accumulator 16, so that accumulator 16 constantly carries out
Energy storage is opened and by section hydraulic oil off-load to oil after the pressure value of accumulator 16 is more than setting pressure by unloading valve 15
In case 22.And overflow valve 14 is then used as safety valve, to control the maximum pressure that hydraulic motor vehicle door arrangement is opened in logistics vehicles side, and
Compartment side door plate 2 is in the state for closing compartment mouth and remains stationary at this time.
Referring to Figure 1 and Fig. 4, when compartment side door plate 2 needs to open, by controller 21 to a of solenoid directional control valve 18
End is powered, make solenoid directional control valve 18 therefrom bit transition to left side operating position, so that accumulator 16 and oil pump 12 pass through simultaneously
After crossing solenoid directional control valve 18, liquid is provided to the lower port of elevating ram 7 using hydraulic control one-way valve 19 and one-way throttle valve 20
Pressure oil.Since the hydraulic oil that accumulator 16 and oil pump 12 provide simultaneously enters elevating ram 7 from the lower port of elevating ram 7
Lower end is intracavitary, moves up the extension bar 71 of elevating ram 7 rapidly, so that the master slider 6 being connected with extension bar 71
Rapidly move up, the master connecting-rod 3 being hinged and connected with master slider 6 is protruding therewith, compartment side door plate 2 is propped up outward with
Compartment side door plate 2 is completed by 1 opening action of compartment.In addition, being conveyed simultaneously to elevating ram 7 in accumulator 16 and oil pump 12 hydraulic
In the process of oil, the pipeline that accumulator 16 conveys hydraulic oil to elevating ram 7 can be cut off by hand-operated direction valve 17, so that only
There is oil pump 12 to convey hydraulic oil to elevating ram 7, cabin side panel 2 can in this way be swung up with relatively slow speed
Compartment 1 to be opened.At the same time, when being lifted up master slider 6 by the extension bar 71 of elevating ram 7, when master slider 6 is opposite
After sliding slot 10 slides upwards and touches upper stroke switch 5, controller 21 controls the end a power loss of solenoid directional control valve 18, makes electromagnetism
Position in the recovery of reversal valve 18, compartment side door plate 2 can be always maintained at opening-wide state, to facilitate progress cargo to move and guarantee work
Safety.
Fig. 3 and Fig. 4 are referred to, when compartment side door plate 2 needs to be re-closing off compartment 1, is changed by controller 21 to electromagnetism
It is powered to the end b of valve 18, so that solenoid directional control valve 18 is in right side operating position, is passed through from oil pump 12 and/or accumulator 16
The hydraulic oil for crossing solenoid directional control valve 18 is intracavitary from the upper end that the upper port of elevating ram 7 enters to elevating ram 7, passes through hydraulic oil
Push extension bar 71 to moving inside elevating ram 7, at the same time, master connecting-rod 3 is by 6 drag down of master slider, and then master connecting-rod 3
The one end being connected with compartment side door plate 2 drags compartment side door plate 2 and is closed to lower swing with compartment 1 is open.It is downward in master connecting-rod 3
In mobile process, slave connecting rod 4 moves down also with master connecting-rod 3 and moves closer to 1 edge of compartment, make elevating ram 7 also with
Move down, after secondary sliding block 4 gradually touches lower stroke switch 9, controller 21 control solenoid directional control valve 18 the end b lose
Electricity makes position in the recovery of solenoid directional control valve 18, so that compartment side door plate 2 is always maintained at closing 1 state of compartment, prevents cargo from transporting
It is poured out during defeated.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or
Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
