According to an aspect of the utility model, a put hand rack is provided.

Fig. 1 is a schematic view of a folded state structure of a hand rest. The hand rest shown in fig. 1 includes: hand rest board 1, lifting subassembly 2 and prevent pressing from both sides subassembly 3. The lifting assembly 2 comprises a fixed end 27 and a lifting end 26, wherein the fixed end 27 of the lifting assembly 2 is fixed in position during the lifting process of the hand resting plate 1. The hand resting board 1 is fixed on a lifting end 26 of the hand resting board 1, and the lifting end 26 can drive the hand resting board 1 to ascend or descend. The upper surface of the hand placing plate 1 is always kept horizontal in the ascending process or the descending process of the hand placing plate 1. When the hand rest 1 is in the state shown in fig. 1, that is, the hand rest 1 is in the retracted position (first position), the hand rest is in the retracted state.

Fig. 2 is a structural diagram illustrating a raised state of the hand rest in fig. 1. The lifting assembly 2 can lift or lower the hand resting plate 1. When the rising end 26 of the lifting assembly 2 rises, the hand rest 1 is brought to the raised position (second position), and the hand rest is brought to the raised state shown in fig. 2. When the hand placing plate 1 is in the lifting position (second position) shown in fig. 2, an included angle is formed between the hand placing plate 1 and the lifting assembly 2. Prevent pressing from both sides subassembly 3 and set up in lifting subassembly 2 to be located lifting subassembly 2 with put the relative one side of palm 1 for whether there is the barrier between detection lifting subassembly 2 and the palm 1 of putting, for example: the human hand. Prevent pressing from both sides subassembly 3 and detect lifting subassembly 2 and put when having the staff between the palm 1, the motion of stopping lifting subassembly 2 that can be timely to prevent to press from both sides the staff between putting palm 1 and lifting subassembly 2, thereby cause the unnecessary harm.

In some embodiments, the side of the hand rest board 1 facing away from the lifting assembly 2 is provided with an elastic pad 4, that is, the elastic pad 4 is provided on the upper surface of the hand rest board 1, and the material of the elastic pad 4 may be, but is not limited to: sponges, foams or animal skins, and the like.

Figure 3 is a schematic cross-sectional view of the hand rest in the raised state. The lift assembly 2 comprises: lifting plate 21, base 22, upper connecting plate 23, lower connecting plate 24 and telescopic link 25. The lifting plate 21 and the upper connecting plate 23 are rotatably connected through a first pin shaft 221, the upper connecting plate 23 and the base 22 are rotatably connected through a second pin shaft 222, the lifting plate 21 and the lower connecting plate 24 are rotatably connected through a third pin shaft 223, and the lower connecting plate 24 and the base 22 are rotatably connected through a fourth pin shaft 224, so that the lifting plate 21, the base 22, the upper connecting plate 23 and the lower connecting plate 24 form a four-bar mechanism. The first pin 221, the second pin 222, the third pin 223 and the fourth pin 224 are respectively a first rotation center, a second rotation center, a third rotation center and a third rotation center of the four-bar linkage. The telescopic rod 25 is connected at both ends thereof to the base 22 and the upper connecting plate 23, respectively. When the telescopic rod 25 is extended, the lifting plate 21 as the lifting end 26 is pushed to ascend; when the telescopic rod 25 is contracted, the lifting plate 21 as the lifting end 26 is pushed down, so that the hand resting plate 1 fixed to the lifting plate 21 is changed between the first position and the second position. The extension pole 25 may be, but is not limited to, a power push rod.

Referring to fig. 3, the lifting plate 21 includes a first end surface 211 and a second end surface 212, and the first end surface 211 intersects the second end surface 212 such that the cross-sectional shape of the lifting plate 21 forms an L-shape. One end of the hand placing plate 1 is hinged at the intersection of the first end surface 211 and the second end surface 212, and the first end surface 211 is in surface contact with the hand placing plate 1. Put palm 1 and set up in lifter plate 21 through a pivot rotation to make and put palm 1 and alternate the second position from first position, if put and have the staff between palm 1 and the upper junction plate 23 and prevent that the clamping component 3 is malfunctioning and fail to stop the action of lifting component 2, put palm 1 can automatic upwards rotatory after touchhing the staff, thereby further prevent to press from both sides and hinder the staff.

Referring again to fig. 3, the anti-pinch assembly 3 includes: an anti-pinch sensing plate 31 and a pressure sensor 32. Prevent pressing from both sides tablet 31 and set up the upper surface in the upper junction plate 23 of lifting subassembly 2 to prevent pressing from both sides tablet 31 and be fixed in upper junction plate 23 through a plurality of elastic mechanism 33, thereby make and prevent forming the interval space between tablet 31 and the upper junction plate 23. The anti-pinch sensing plate 31 is movable toward the upper connecting plate 23 when it receives pressure, and returns to its original position when the pressure is removed. Pressure sensor 32 set up in prevent pressing from both sides deviating from of tablet 31 one side of putting palm board 1, pressure sensor 32's detection end 321 is located in the interval space. The main body of the pressure sensor 32 is fixed to the upper connecting plate 23, the detecting end 321 of the pressure sensor 32 is located in the space, and when the anti-pinch sensing plate 31 moves down, it will abut against the detecting end 321, and the pressure sensor 32 releases an electrical signal to stop the extension and retraction of the telescopic rod 25, so as to stop the movement of the lifting assembly 2.

Fig. 4 is an enlarged schematic view of the region a in fig. 3. The elastic mechanism 33 is shown in fig. 4 to include a guide post 331 and a compression spring 332. One end of the guide post 331 is fixed to the lifting assembly 2, and the other end thereof penetrates through the anti-pinch sensing plate 31. The compression spring 332 is sleeved on the guide post 331 and located on the side of the anti-pinch sensing plate 31 away from the hand rest 1. The two ends of the compression spring 332 respectively prop against the anti-pinch sensing plate 31 and the lower connecting plate 24, so that the anti-pinch sensing plate 31 is compressed by pressure and props against the detection end 321 of the pressure sensor 32; after the pressure is removed, the original state can be recovered.

Fig. 5 is a structural schematic diagram of the hand placing frame after the hand placing plate is turned over. Put palm 1 and set up in lifter plate 21 through a pivot rotation to make and put palm 1 and rotate promptly the upset along the pivot, if put and have the staff between palm 1 and the upper junction plate 23 and prevent that the malfunction of clamping subassembly 3 fails to stop the action of lifting subassembly 2, put palm 1 can automatic upwards rotatory after touchhing the staff, thereby further prevent to press from both sides and hinder the staff.

Put palm 1 and in the ascending or decline in-process, formed the shearing position between putting palm 1 and upper junction plate 23, if receive and release in the shearing position promptly between putting palm 1 and upper junction plate 23, electric putter continues drive lifting subassembly 2 and has the risk of tong. The hand clamping injury or other objects can be effectively avoided by the anti-clamping component 3.

According to an aspect of the present invention, there is provided a seat.

Fig. 6 is a schematic structural diagram of a seat. Fig. 6 shows a chair 500 comprising a seat plate 501 and a hand rest 502.
