The pet scanner in the related art is mostly partially modified from the conventional human scanner. The traditional scanning bed has the functions of lifting and horizontal movement, wherein one of the lifting functions is to lower the bed to bring a patient into and out of the bed conveniently, and the other is to adjust the height of the bed according to patients with different body types to ensure that the horizontal center of a patient lying on the bed is equal to the center of a scanning frame so as to ensure that images with higher quality are obtained.

The lifting structure of the scanning bed is usually designed between the bed base and the bed frame, and when the lifting push-pull force is preset, the weight of the bed frame is considered in addition to the weight of the patient, and the weight of the bed frame is generally larger than the weight of the patient, which leads to the increase of the cost of the whole lifting system. In addition, in order to simultaneously meet the functions of getting on and off the patient and scanning, the traditional lifting stroke of the scanning bed can be quite large, animals are held on the scanning bed by doctors, the scanning bed only needs to finely adjust the height of the bed according to animals of different sizes to ensure the quality of scanning images, and the excessive lifting stroke can cause waste.

In view of this, alternative embodiments of the present disclosure are described in detail below with reference to the drawings.

Fig. 1 is a schematic view showing a structure of a scanning bed lifting device according to an exemplary embodiment. Fig. 2 is an enlarged view of a portion of a scanning bed lifting device, according to an exemplary embodiment. Fig. 3 is a cross-sectional view of a scanning bed lifting device, according to an exemplary embodiment. Fig. 4 is a schematic structural view of a crane structure according to an exemplary embodiment.

The embodiment of the disclosure provides a scanning bed lifting device, comprising: the bed board 200, the bed board 100, the sliding module 300, the lifting frame, and the driving motor 500.

The support plate 200 is provided with a first linear guide 210, as shown in fig. 4, the first linear guide 210 is provided on the support plate 200, and the length of the first linear guide 210 limits the maximum distance that the sliding module 300 can move.

The bed plate 100 is disposed on the support plate 200, a second linear guide rail (not shown) is disposed on a side surface of the bed plate 100 opposite to the support plate 200, and the second linear guide rail is disposed in the bed plate 100 and parallel to the first linear guide rail 210, so that the bed plate 100 and the support plate 200 are kept parallel in the horizontal direction in the lifting process of the lifting frame structure.

The sliding module 300 is disposed on the first linear guide 210 and adapted to slide on the first linear guide 210 to drive the lifting frame to lift.

Specifically, the lifting frame includes a first connecting rod 410 and a second connecting rod 420, the first connecting rod 410 is cross-connected with the second connecting rod 420, a fixed end of the first connecting rod 410 is connected with the sliding module 300, and a fixed end of the second connecting rod 420 is connected with the bed board 100.

The first connecting rod 410 and the second connecting rod perform a scissor motion to support the bed board to lift.

Further, when the sliding module 300 slides on the first linear guide 210, the fixed end of the first connecting rod 410 may be driven to move in a direction approaching to the fixed end of the second connecting rod 420, and at this time, the height of the lifting frame is raised, and the distance between the bed plate 100 and the support plate 200 is increased.

Similarly, when the sliding module 300 slides on the first linear guide 210, the fixed end of the first connecting rod 410 may be driven to move away from the fixed end of the second connecting rod 420, and at this time, the height of the lifting frame is lowered, and the distance between the bed board 100 and the support board 200 is reduced.

Further, the driving motor 500 may drive the screw 510 to rotate in the first direction or the second direction by rotating in the forward or reverse direction.

When the driving motor 500 rotates forward, the screw 510 rotates in a first direction, the sliding module 300 is adapted to drive the fixed end of the first connecting rod 410 to move in a direction approaching to the fixed end of the second connecting rod 420, and at this time, the lifting frame rises in height, and the distance between the bed board 100 and the supporting board 200 increases.

When the driving motor 500 is reversed, the screw 510 rotates in the second direction, and the sliding module 300 is adapted to drive the fixed end of the first connecting rod 410 to move in a direction away from the fixed end of the second connecting rod 420, at this time, the height of the lifting frame is lowered, and the distance between the bed board 100 and the supporting board 200 is reduced.

It should be noted that, the driving motor 500 of the present disclosure is movably connected with the sliding module 300 through the screw rod 510, so that the height control of the driving motor 500 on the lifting frame can be achieved without a coupling structure between the first connecting rod 410 and the second connecting rod 420, and the structure of the scanning bed lifting device 1000 is more compact and the driving power required to be consumed is smaller while the production cost is reduced.

In some embodiments, the sliding module 300 includes: slider 310 and nut 320.

The sliding block 310 is disposed on the first linear guide 210, and is configured to slide on the first linear guide 210, so as to drive the first connecting rod 410 to move by the nut 320, thereby adjusting the height of the lifting frame.

The nut 320 is movably connected with the screw 510, and is adapted to move on the screw 510 according to the rotation direction of the screw 510.

Specifically, when the driving motor 500 rotates forward, the screw 510 rotates in a first direction, the nut 320 is adapted to drive the slider 310 to move on the first linear guide 210 in a direction approaching to the fixed end of the second connecting rod 420, and at this time, the slider moves with the nut 320 simultaneously with the fixed end of the first connecting rod 410, the height of the lifting frame increases, and the distance between the bed plate 100 and the support plate 200 increases.

When the driving motor 500 is reversed, the screw 510 rotates in the second direction, the screw 320 is adapted to drive the slider 310 to move on the first linear guide 210 in a direction away from the fixed end of the second connecting rod 420, and at this time, the slider moves with the screw 320 simultaneously with the fixed end of the first connecting rod 410, the height of the lifting frame is lowered, and the distance between the bed board 100 and the support board 200 is reduced.

In some embodiments, as shown in fig. 3 and 4, a limiting member 511 is disposed on an end of the screw 510 away from the driving motor 500, for limiting a maximum moving distance of the screw 320 on the screw 510.
