A kind of realization of the foot structure of robot provided by the invention is carried out in detail below in conjunction with attached drawing 1 to Figure 10
Description.
As shown in Figure 1, the foot structure of the robot, including foot's main body 20 and to drive foot's main body 20 to move
Switching support 10.It should be noted that then as shown in Figure 1, switching support 10 includes connection frame 11 and is set to 11 both ends of connection frame
On engaging lug 12.In general, connection frame 11 connects foot's main body 20, engaging lug 12 connects ankle two sides with connected legs and foot
Portion.It is to be appreciated that switching support 10 can link foot's main body 20 relative to leg exercise under the action of ankle.Specifically exist
In the present embodiment, foot's main body 20 can move back and forth, and can also swing.So foot's row of the mankind can be imitated substantially
It walks.
In the present embodiment, foot's main body 20 includes instep shell 100 and sole 200, wherein sole 200 includes bottom plate 210
With backing plate 220.As shown in figure 3, instep shell 100 is formed with cavity 110, wherein the cavity 110 can be used to mounting circuit boards
600, the components such as force snesor 700.As shown in Figure 1, the middle section of instep shell 100 is connected with switching support 10, in this way, i.e.
It can ensure that the gravitation energy of the foot of robot or more concentrates on the centre of foot's main body 20 as far as possible, be conducive to guarantee that robot is whole with this
The stationarity of body.
As shown in Figure 3 and Figure 7, bottom plate 210 is equipped with bearing wall 211 and connection wall 212, and as its name suggests, bearing wall 211 is main
For gravity more than foot, support bearing robot, connection wall 212 is mainly used to connection backing plate 220, so, in general, bottom plate
210 are made of rigid material, and specifically, bottom plate 210 can be handware.Wherein, as shown in Figure 3 and Figure 4, bottom plate 210
Bearing wall 211 is connected on instep shell 100, and the lid of bottom plate 210 closes cavity 110 with closed cavity 110.
It is to be appreciated that the size and shape of the bearing wall 211 of bottom plate 210 size with the opening of cavity 110 respectively
And shape adaptation.Specifically in embodiment, for convenience of bottom plate 210 to be connected on instep shell 100, as shown in figure 3, instep shell
It is convexly equipped with connecting column 140 in 100 cavity 110, threaded hole (not shown) is offered on connecting column 140, is offered on bottom plate 210
Bottom plate 210 can be realized by the way that the screw pieces such as screw or screw are sequentially plugged on connecting hole 213 and threaded hole in connecting hole 213
Connection between instep shell 100.
As shown in Figure 7 to 9, backing plate 220 is equipped with buffer wall 221 and the wall 222 that contacts to earth with ground face contact.Wherein, such as Fig. 4
