Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, can be easier to be those skilled in the art will recognize that to make advantage of the present utility model and feature thus more explicit defining is made to protection domain of the present utility model.
fig. 1, to the wheel mechanism that Figure 3 shows that a kind of perambulator, is specially the rear wheel mechanism of perambulator.Described perambulator comprises vehicle frame, vehicle frame comprises after poppet 1 and the lower supporter 2 in the arc protruded downwards, the end of after poppet 1 and lower supporter 2 is fixedly connected with after poppet joint 11 and lower supporter joint 21 respectively, and after poppet joint 11 and lower supporter joint 21 are rotated by pivot and be connected.This wheel mechanism comprises link span 3, have the wheel 4 of control position and upturned position and be arranged at for wheel 4 being locked in the lockout mechanism of control position and upturned position on the lower supporter joint 21 of described vehicle frame and link span 3, and one end of described link span 3 is connected to described lower supporter joint 21(or after poppet joint 11 rotationally by pivot), the other end is connected to described wheel 4 rotationally.Particularly, the other end of link span 3 is rotationally connected with on the turning cylinder of wheel 4, makes wheel 4 can around own axis.
when described wheel 4 is at control position, as shown in Figure 1, described wheel 4 below that is positioned at the lower supporter 2 of vehicle frame is formed perambulator and to support and its periphery rollably contacts mutually with ground.When described wheel 4 is at upturned position, as shown in Figure 3, described wheel 4 upwards overturns to draw close mutually with vehicle frame, the lowest part of described lower supporter 2 is lower than the lowest part of wheel 5, and vehicle frame kiss the earth forms support to perambulator, particularly, wheel 4 turn to the top of lower supporter 2, and lower supporter 2 can swingly contact with ground.
described lockout mechanism comprises the first lockout mechanism and the second lockout mechanism, described first lockout mechanism comprise be movably set in described link span 3(or vehicle frame 1) on stop pin 31, the lower supporter joint 21(being opened in described vehicle frame or attaching parts 3) on the locked groove 22 matched with stop pin 31, when described stop pin 31 inserts described locked groove 22, described wheel 4 is locked in control position.Particularly, described lockout mechanism comprises the elastic component be connected between described stop pin 31 and link span 3, and this elastic component is stage clip 32, and stop pin 31 utilizes the elasticity of stage clip 32 can move relative to link span 3, thus inserts or depart from locked groove 22 realization locking or unlock.
described locked groove 22 is opened in the bottom of the lower supporter joint 21 of vehicle frame and the notch had downward, stop pin 31 is along length direction the moving radially namely along wheel 4 of link span 3. and when described wheel 4 is at control position, described lock pin 31 can be provided with on link span 3 along the vertical direction movably.When described stop pin 31 inserts described locked groove 22, described wheel 4 is locked in control position.Vehicle frame 1 is also by electric bell and link span 3 phase the locking and unlocking.
described second lockout mechanism comprise be opened in described link span 3(or vehicle frame 1) on groove 33, the lower supporter joint 21(being fixedly installed on described vehicle frame or link span 3) on the projection 23 matched with described groove 33, when described protruding 23 insert described groove 33, described wheel 4 is locked in upturned position.
during described first lockout mechanism locking, described stop pin 31 is relative to the link span 3 or vehicle frame 1 elastic movement that arrange this stop pin; During described second lockout mechanism locking, described protruding 23 maintain static relative to the link span 3 or vehicle frame 1 that arrange this projection 23.
shown in composition graphs 2 and Fig. 3, when wheel 4 transfers upturned position to by control position, downward promotion stop pin 31, along with the relative link span 3 of stop pin 31 moves down, while stage clip 32 compresses, stop pin 31 departs from from the notch of locked groove 22, link span 3 and lower supporter joint 21 unlock, rotating-wheel 4 or link span 3 in the counterclockwise direction, after when link span 3, lower supporter joint 21 turns to the assigned address be positioned at above end vehicle frame relatively, when groove 33 on link span 3 arrives projection 23 place of lower supporter joint 21, protruding 23 to insert in grooves 33 thus link span 3 and lower supporter joint 21 to be locked, and then wheel 4 is locked in upturned position.
the vehicle frame of this perambulator is collapsible, when described vehicle frame folding, and vehicle frame folding, and described wheel 4 is converted to upturned position and vehicle frame is drawn close further, makes the perambulator volume very compact after folding, is convenient to deposit and carry.
because the described lower supporter 2 of vehicle frame bottom is in the arc protruded downwards, when described wheel 4 is at upturned position, the lowest part of described wheel 4 higher than or the highest point that flushes in vehicle frame bottom, namely wheel 4 turn to the top of lower supporter 2, lower supporter 2 kiss the earth is made to be formed can swingly support this perambulator, make this perambulator have swing function, rocking chair can be equivalent to and use.
above-described embodiment is only for illustrating technical conceive of the present utility model and feature; it is a kind of preferred embodiment; its object is to person skilled in the art can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalent transformations of doing according to Spirit Essence of the present utility model or modification, all should be encompassed within protection domain of the present utility model.
