Order member is separately mounted in symmetrical fashion at left and right sides of lead screw, and the connection unit includes connecting rod and link block, the company
One end of extension bar and screw slider are hinged, and the other end and link block of the connecting rod are hinged, and the link block is mounted on expansion
On case；The position-limiting unit includes first stroke switch and second stroke switch, and the first stroke switch and second stroke are opened
The side and top for being separately mounted to vehicle frame at left and right sides of lead screw are closed, the first stroke switch and second stroke switch are used to
The extreme position of case movement is expanded in limitation, and the first stroke switch and second stroke switch are connect with controller respectively.
Further, the link block is fixed on by welding or bolt and is expanded on case.
Further, the connecting rod is unfolded or is closed when screw slider is axially moved along lead screw.
Further, it is pushed when the connecting rod does expansion or closing motion and expands case movement, realized and expand beating for case
Open and close are closed.
Further, the controller control motor rotates and reverse, and realizes the rotary motion of lead screw, passes through the rotation of lead screw
Turn that screw slider is driven to axially move on lead screw.
Compared with prior art, the positive beneficial effect of the utility model is:
The electronic expanding body of a kind of herringbone of the utility model, using lead screw and screw slider as movement interpreter
Structure；Controller controls motor positive and inverse, since the output end of motor is connect with lead screw, so the rotary motion of motor passes to silk
Thick stick realizes the positive and negative rotation of lead screw, and lead screw only makes rotating motion, and does not axially move, and drives screw slider by the rotation of lead screw
It axially moving and does not make rotating motion on lead screw, connecting rod is unfolded when screw slider is axially moved along lead screw or closure, into
And connecting rod pushes and expands case movement, realizes the open or close for expanding case.The utility model greatly reduces caravan realization and opens up
The cost of function is opened up, structure is simple, easy to maintenance.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of the electronic expanding body of herringbone of the utility model；
Fig. 2 is the attachment structure schematic diagram of screw slider and connecting rod；
Fig. 3 is the attachment structure schematic diagram of connecting rod and link block.
Meaning representated by serial number in figure are as follows: 1. lead screws, 2. screw sliders, 3. connecting rods, 4. link blocks, 5. expand case,
6. first stroke switchs, 7. motors, 8. controllers, 9. second strokes switch.
Specific embodiment
Embodiment one, as shown in Figure 1, the electronic expanding body of a kind of herringbone provided in this embodiment, comprising control unit,
Spindle arrangement, connection unit and position-limiting unit；Described control unit includes controller 8 and motor 7, the controller 8 and motor 7
Connection；The spindle arrangement includes lead screw 1 and screw slider 2, and the lead screw 1 is connect with the output end of motor 7, and the lead screw is sliding
Block 2 is by thread set on lead screw 1；The connection unit is separately mounted to 1 left and right sides of lead screw, the company in symmetrical fashion
Order member includes connecting rod 3 and link block 4, as shown in Fig. 2, one end of the connecting rod 3 and screw slider 2 are hinged, such as Fig. 3 institute
Showing, the other end and link block 4 of the connecting rod 3 are hinged, and the link block 4, which is mounted on, to be expanded on case 5, preferably, institute
Link block 4 is stated to be fixed on expansion case 5 by welding or bolt.
The position-limiting unit includes first stroke switch 6 and second stroke switch 9, the first stroke switch 6 and second
Travel switch 9 is separately mounted to the side and top of 1 left and right sides vehicle frame of lead screw, the first stroke switch 6 and second stroke
Switch 9 is used to limitation and expands the extreme position that case 5 moves, the first stroke switch 6 and second stroke switch 9 respectively with control
Device 8 processed connects；When expanding case 5 and withdrawing, touch arrives second stroke switch 9 to first stroke switch 6 or the touch of connecting rod 3,
The control circuit of motor 7 is disconnected, motor 7 stops operating.
Working principle is as follows:
Controller 8 controls 7 positive and negative rotation of motor, since the output end of motor 7 is connect with lead screw 1, can pass through control motor 7
The positive and negative rotation of lead screw 1 is realized in positive and negative rotation, and lead screw 1 only makes rotating motion, do not axially move, and drives silk by the rotation of lead screw 1
Thick stick sliding block 2 axially moves on lead screw 1 not to make rotating motion, the exhibition when screw slider 2 is axially moved along lead screw 1 of connecting rod 3
Open perhaps to be closed when connecting rod 3 does expansion or closing motion to push and expand case 5 and move, thus realize the opening for expanding case 5 or
Person's closure.When the expansion case 5 moves to two extreme positions, first stroke switch 6 or second stroke switch 9 can be touched,
The control circuit of motor 7 is disconnected, motor 7 stops operating, lead screw 1, screw slider 2 and the equal stop motion of connecting rod 3, to make to open up
Open up 5 stop motion of case.
A kind of electronic expanding body of herringbone of the utility model is used as driver using lead screw 1 and lead screw sliding shoe 2
Structure, structure is simple, and production cost is greatly saved, also convenient for maintenance.
The above-mentioned description to embodiment is for that can understand and apply this practical convenient for those skilled in the art
