Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Embodiment 1
A kind of standing lifting mechanism of multifunctional wheelchair as shown in Figure 1, including support plate 1, worm screw 8, the support plate 1 one
The first fixed bearing block 2, the second fixed bearing block 3 are separately installed on side wall, first fixed bearing block 2 and second is fixed
Threaded rod 4 on bearing block 3 is installed, is opened in the support plate 1 between 2 and second fixed bearing block 3 of the first fixed bearing block
Equipped with the first sliding groove 5, the seat helical rack 6 that can slide up and down in the first sliding groove 5 is installed, is installed on the threaded rod 4
Have and the first connected helical gear 7 is engaged with seat helical rack 6, described 4 one end of threaded rod is connected with lifting motor 9, the screw thread
4 other end of bar is connected with turbine 10；The second sliding slot 11 is offered on 1 another side wall of support plate, in second sliding slot 11
The backrest helical rack 12 that can slide up and down is installed, second for engaging and being connected with backrest helical rack 12 is installed on the worm screw 8
Helical gear 13, the worm screw 8 engages with turbine 10 to be connected.
The seat helical rack 6 is connected with seat support 14, and the backrest helical rack 12 is connected with back rest supports plate 15.
Pyroscan 16, alarm 17, the infra-red detection are separately installed on second fixed bearing block 3
Device 16 is connected with alarm 17.It is connected since worm screw 8 is distributed with support plate 1 with wheelchair, worm screw 8 needs in real time with turbine 10
Ensure that engagement is connected, once this worm screw 8 departs from turbine 10, can not just realize the effect of the lifting chair back.Pyroscan 16
Setting can monitor whether worm screw 8 engages with turbine 10 in real time, once worm screw 8 departs from turbine 10, pyroscan 16
Alarm signal is just sent by alarm 17, so as to reduce security risk.
A kind of standing lifting mechanism of multifunctional wheelchair described in the present embodiment when in use, when lifting motor 9 rotate band
Dynamic threaded rod 4 makes the first helical gear 7 on threaded rod 4 drive seat helical rack 6, and fortune up and down is done so as to fulfill seat helical rack 6
It is dynamic, achieve the effect that make chair cushion lifting.Turbine 10 is engaged with worm screw 8 simultaneously is connected, and threaded rod 4 drives turbine while rotation
10, turbine 10 drives worm screw 8, and worm screw 8, which rotates, rotates the second helical gear 13 being mounted on worm screw 8,13 band of the second helical gear
Dynamic backrest helical rack 12, moves up and down so as to fulfill backrest helical rack 12, achievees the effect that chair back lifting.When leading for worm screw 8
When journey angle is less than the equivalent friction angle of engagement wheel between cog, mechanism has self-locking performance, it can be achieved that reverse self-locking.
A kind of standing lifting mechanism of the multifunctional wheelchair of the present embodiment, it is simple in structure, it is easy to use, it can realize seat
