When the supporting tool is implemented as a stool, the supporting surface formed by the supporting tool can be used for supporting a user, so that the user can sit on the supporting tool smoothly. In certain circumstances it is important that the bearing surface formed by the support tool remains level.

When the ground supporting the supporting tool is swayed, for example, the ground supporting the supporting tool is a ship deck, the ground supporting the supporting tool is swayed during the running of the ship, so that the supported object supported on the supporting tool can be affected to a certain extent. For example, when the supporting tool is implemented as a stool and is used to support a user, if the supporting tool is shaken vigorously, the user supported on the carrying surface may be dizzy.

For another example, when the supporting tool is implemented as a table and is used to support a precision measuring instrument, if the bearing surface formed by the supporting tool is inclined, a large error may be generated in the measurement result formed by the precision measuring instrument.

The fundamental reason for the above problems is that the angle of the bearing surface formed by the supporting tool in the prior art with respect to the ground is usually fixed, and when the bearing surface is inclined, the position of the bearing surface cannot be automatically adjusted to keep the bearing surface formed by the supporting tool horizontal.

Referring to fig. 1 to 8B, a supporting tool 100 according to an embodiment of the present invention will be described in detail below, wherein the supporting tool 100 can be used to support at least one supported body.

Referring to fig. 1 and 2, the supporting tool 100 of the present invention includes a tool body 10 and a level 20. The tool body 10 forms a bearing surface 101 at a predetermined height for supporting the supported body at the predetermined height. The level gauge 20 is configured to monitor the spatial position of the carrying surface 101, and automatically adjust the spatial position of the carrying surface 101 formed by the tool body 10 according to the monitoring result, so that the carrying surface 101 formed by the tool body 10 is kept parallel to the horizontal plane.

Specifically, the tool body 10 of the supporting tool 100 includes a base 11 and a carrying seat 12. The base 11 has a bottom surface 1101 that is used to support the support apparatus 100 on a surface, such as a ship deck, such as the ground. The top surface of the supporting base 12 forms a supporting surface 101 for supporting the supported body. As will be appreciated by those skilled in the art, the supported object may be an article or a person.

Referring to fig. 2 and 3, the level 20 includes a sliding pendulum assembly 21 and a monitoring assembly 22. The carriage 12 is swingably supported on the base 11 by the sliding pendulum assembly 21. The monitoring assembly 22 is configured to monitor whether the bearing surface 101 has a changed spatial position, such as a changed spatial position relative to a location, such as the bearing surface 101 being parallel to a horizontal plane. When the bottom 1101 of the base 11 is monitored to be inclined with respect to the horizontal plane, the monitoring unit 22 controls the sliding axis rotating unit 21 so that the bearing surface 101 is kept parallel with respect to the horizontal plane.

Referring to fig. 1 to 3, the sliding pendulum assembly 21 includes a pendulum rod 211, at least one slider 212, at least one driving unit 213, and at least one fixed shaft 214. The sway bar 211 has a high end 21101 and a low end 21102 opposite the high end 21101.

Optionally, the fixed shaft member 214 has at least a partial spherical surface. In one embodiment, as shown in FIG. 5A, the fixed shaft member 214 comprises a sphere. In this embodiment, as shown in fig. 2, the upper surface of the base 11 is a circular arc surface 1102, and a mounting hole 1103 is formed in the center of the circular arc surface 1102. As shown in fig. 5, the sphere diameter of the fixed shaft member 214 is larger than the diameter of the mounting hole 1103. During installation, the sphere of the fixed shaft 214 is placed into the installation hole 1103 from top to bottom and is clamped at the position 1103, so that the superstructure can be supported very firmly.

The bottom of the carrier 12 is fixed to the upper end of the fixed shaft 214, and the lower end of the fixed shaft 214 is fixedly connected to the high end 21101 of the swing lever 211, so that during the swing process, the position of the bottom surface of the carrier 12 relative to the high end 21101 of the swing lever is not changed, and a fixed angle, such as 90 degrees, is always formed between the bottom surface of the carrier 12 and the longitudinal axis of the swing lever 211.

The lower end 21102 of the swing lever 211 is swingably mounted somewhere on the surface of the slider 212. During the oscillation, the angle between the surface of slider 212 and the longitudinal axis of oscillating rod 211 changes.

In one embodiment, as shown in FIG. 5C, the lower end 21102 of the sway bar is attached to a stationary member 21104 by a hinge 21103, and the stationary member 21104 is fixed somewhere on the surface of the slider 212. The lower end 21102 of the swing lever is thus able to rotate about the axis of rotation of the hinge 21103.

The lower end 21102 of the swing lever 211 is swingably attached to the surface of the slider 212, but the present invention is not limited to the structure of the embodiment of fig. 5C, and other universal joints, fisheye connectors, knuckle bearings, and the like can also realize similar functions.

When the sliding block 212 is driven by the driving unit 213 to slide relative to the base 11, the lower end 21102 of the swing rod 211 is driven to slide together, so as to drive the swing rod 211 to swing around the fixed shaft 214. When the swing rod 211 swings, the upper end 21101 of the swing rod drives the carrier 12 to rotate through the fixed shaft element 214, thereby adjusting the tilting direction of the carrier 12. The fixed shaft member provides a seesaw-like fulcrum, one end of which is connected to the lower end 21102 of the swing lever, and the other end of which is connected to the carrier 12, and when one end rotates, the other end is driven to rotate.

Optionally, in the present invention, the sliding pendulum assembly 21 includes a first slider 212a, a second slider 212b, a first driving unit 213a and a second driving unit 213 b. The first slider 212a is relatively slidably disposed on the base 11 by the first driving unit 213 a. The second slider 212b is disposed between the first slider 212a and the base 11, and is slidably disposed on the base 11 by the second driving unit 213 b. That is, when the first slider 212a is driven by the first driving unit 213a to slide, the first slider 212a slides with respect to the second slider 212 b. And when the second slider 212b is driven by the second driving unit 213b to slide, the second slider 212b slides with the first slider 212 a.

Alternatively, the first slider 212a and the second slider 212b slide in two directions that are not collinear when driven to slide. Alternatively, in the present invention, the sliding directions of the first slider 212a and the second slider 212b are implemented as two orthogonal directions. Therefore, the position of the lower end 21102 of the swing lever can be moved quickly in the two-dimensional plane by sliding the

sliders

212a and 212 b. In this way, the angle of the bearing surface 101 of the bearing seat 12 relative to the horizontal direction can be quickly adjusted.

It can be understood by those skilled in the art that, in the present invention, the first driving unit 213a and the second driving unit 213b may be implemented as a servo motor, a hydraulic driving device, etc., and the present invention is not limited in this respect.

Further, in the present invention, the movement of the sliding pendulum assembly 21 is controlled by the monitoring assembly 22. Specifically, the driving unit 213 of the sliding pendulum assembly 21 is controlled by the monitoring assembly 22. The monitoring component 22 is configured to detect an angle between the bearing surface 101 of the bearing seat 12 and a horizontal direction, and when the bearing surface 101 of the bearing seat 12 is inclined with respect to the horizontal plane, the monitoring component 22 automatically calculates and drives the sliding shaft pendulum component 211 to perform a certain amplitude of swing, so as to adjust the inclination angle of the bearing surface 101 on the bearing seat 12, thereby maintaining the bearing surface 101 parallel with respect to the horizontal plane.

Referring to fig. 1-4, in particular, the monitoring assembly 22 includes a controller 221 and an angle sensor 222.

The angle sensor 222 is configured to detect the inclination angle of the carrier 12 with respect to the horizontal plane. The angle sensor 222 may be implemented as an electromagnetic sensor, optical sensor, or the like.

The controller 221 can control the driving unit 213 to drive the slider 212 to slide.

In one embodiment, the angle sensor 222 and the controller 221 are disposed on the tool body 10.

Alternatively, a positioning point (facet) capable of keeping its position (horizontal tilt angle and/or height, etc.) still may be provided, and the angle sensor 222 may use the positioning point (facet) as a reference point to determine whether the bearing surface is tilted with respect to the horizontal plane.

In one embodiment, the location point is provided by an automated spatial stabilization system, such as a self-stabilizing pan/tilt head. The self-stabilization pan-tilt is now mostly used for anti-shake of shooting of cameras and video cameras, such as hand-held shooting of video cameras. Some self-stabilization holders acquire data of angular velocity and acceleration through an Inertial Measurement Unit (IMU), and then reversely adjust corresponding angles of motors, thereby realizing position stabilization of an article on the holder.

In another embodiment, the monitoring assembly 22 is implemented to include an aircraft. The aircraft has a hovering function, so that an anchor point capable of keeping the position (horizontal inclination angle, height and the like) of the aircraft immovable can be realized.

As shown in fig. 5 and 6, when the bottom surface of the supporting tool is inclined, such as when the deck of a ship is inclined and swayed, the base 11 is inclined, which also causes the bearing seat 12 and the bearing surface 101 to be inclined, as shown in fig. 5A. At this time, the angle sensor 222 detects that the supporting surface 101 of the supporting base 12 is tilted with respect to the horizontal plane, and reports the tilt result to the controller 221, and the controller 221 automatically calculates and controls the driving unit 213 to drive the sliding block 212 to slide. In fig. 5A, the slider 212 is driven to slide in the direction of the arrow (right direction on the paper) for a certain displacement, and the lower end 21102 of the swing lever 211 is driven to slide in this direction for a certain displacement, so that the state shown in fig. 5B is achieved. In fig. 5B, the lower end 21102 of the swing lever 211 is displaced with respect to the mounting hole 1103 of the circular arc surface of the base 11, and the swing lever 211 is not perpendicular to the slider surface by 90 degrees, but forms an inclination angle, that is, the swing lever 211 swings around the fixed shaft member 214. The fixed shaft 214 provides a seesaw-like pivot, and when the swing lever 211 swings at a certain angle, the upper end of the fixed shaft 214 drives the bearing seat 12 to rotate at a corresponding angle, so as to compensate the inclination of the bottom 1101, and adjust the bearing surface 101 to return to the horizontal direction again, i.e. maintain the bearing surface 101 parallel to the horizontal plane, as shown in fig. 5B and fig. 6.

In one embodiment, the controller 221 can control the first driving unit 213a and the second driving unit 213b to respectively drive the first slider 212a and the second slider 212b to slide in two directions that are not collinear, such as two directions x and y. The lower end 21102 of the swing lever 211 is thus able to slide along with the sliding of the first slider 212a and the second slider 212b, for example, in both the x and y directions, so that the inclination of the bearing surface 101 with respect to the horizontal plane in both directions (the x and y directions) can be adjusted, i.e., any inclination of the bearing surface 101 with respect to the horizontal plane can be adjusted. The slider 212 slides to drive the swing rod 211 to swing, so as to adjust the bearing surface 101 to return to the horizontal direction.

Alternatively, referring to fig. 1 to 3, the bearing surface horizontal protection mechanism 20 includes a lifting assembly 23, wherein the bearing seat 12 is connected to the lifting assembly 23 in a liftable manner. Specifically, the lifting assembly 23 includes a base plate 231 and a telescopic member 232, and the carriage 12 is installed on the base plate 231 in a liftable manner through the telescopic member 232. Referring to fig. 3, the telescopic member 232 is optionally implemented to include at least three telescopic cylinders 2321, a height adjuster 2322 and at least one lift drive 2323. The three telescopic cylinders 2321 are disposed between the bottom surface of the carrier 12 and the top surface of the bottom plate 231. The height adjuster 2322 is also mounted between the bottom surface of the carrier 12 and the top surface of the base plate 231.

Optionally, the height adjuster 2322 has a top end 232201 and a bottom end 232202. The base plate 231 is mounted to the bottom end 232202 of the height adjuster and the carrier 12 is mounted to the top end 232201 of the height adjuster. The height adjuster 2322 further has two horizontal compression ends 232203 and 232204, and the lifting driver 2323 can drive the distance between the horizontal compression ends 232203 and 232204 of the height adjuster 2322 to change (i.e. horizontally compress and extend), so as to change the distance between the top end 232201 and the bottom end 232202 of the height adjuster (i.e. change the height).

In one embodiment, the monitoring assembly 22 further includes a distance sensor 223.

In one embodiment, the distance sensor 223 is provided to the tool body 10. Optionally, the tool body 10 comprises a bracket 13, wherein the bracket 13 is fixed on the carrying seat 12, and the bracket 13 forms a high end 131 with respect to the carrying seat 12. The distance sensor 223 is provided at the high end portion 131.

The controller 221 is electrically connected to the distance sensor 223. For example, when the carrier 12 is shaken up or down, the distance sensor 223 can detect that the bearing surface 101 of the carrier 12 is deviated from the original height. Accordingly, the controller 221 automatically controls and drives the lifting driver 2323 to operate according to the detection result of the distance sensor 223, so that the bearing surface 101 returns to the original height, as shown in fig. 7.

It will be appreciated by those skilled in the art that the distance sensor 223 may be implemented as an acoustic wave sensor, a light sensor, or the like.

Optionally, an anchor point capable of keeping its height constant is provided, and the distance sensor 223 uses the anchor point as a reference point to determine whether the height of the bearing surface 101 has changed.

In one embodiment, the location point is provided by an automated spatial stabilization system, such as a self-stabilizing pan/tilt head. The self-stabilization pan-tilt is now mostly used for anti-shake of shooting of cameras and video cameras, such as hand-held shooting of video cameras. Some self-stabilization holders acquire acceleration data through an Inertial Measurement Unit (IMU), and then reversely adjust the corresponding height of a motor, thereby realizing the position stabilization of an object on the holder.

In another embodiment, the monitoring assembly 22 is implemented to include an aircraft. The aircraft has a hovering function, so that an anchor point capable of keeping the height of the aircraft immovable can be realized.

From the above description, it can be understood by those skilled in the art that, when the supporting tool 100 is shaken violently, the height and the angle of the supporting surface 101 formed by the tool body 10 of the present invention with respect to the horizontal direction can be automatically adjusted, so that the spatial height of the bottom surface 1101 formed by the tool body 10 is kept constant and the supporting surface 101 formed by the tool body 10 is kept horizontal.

In another embodiment, the monitoring assembly 22 of the present invention is implemented to include an aircraft, wherein the angle sensor 222 and the distance sensor 223 are disposed on the aircraft to detect the deviation of the bearing surface 101 from the original height and the inclination angle of the bearing surface 101 with respect to the horizontal plane through the change of the spatial position of the aircraft with respect to the bearing surface 101.

Referring to fig. 8A and 8B, further, in an alternative embodiment, the tool body 10 further includes a pair of armrests 14, wherein the pair of armrests 14 are respectively disposed at both sides of the support 13, so that the supporting tool 100 is implemented as a stool or a chair. Alternatively, the armrests 14 may be rotatably disposed at both sides of the support 13, so that the armrests 14 can be maintained at different positions by rotating the armrests 14 when a user needs to use the armrests 14.

Referring to fig. 9, a method of adjusting the bearing surface level of a supporting tool according to another aspect of the present invention will be explained in detail below, and in particular, the method of adjusting the bearing surface level of a supporting tool includes the steps of:

9001, monitoring whether the bearing surfaces 101 are parallel; and

9002, when it is detected that the bearing surface 101 is not parallel to the horizontal plane, the controller drives the sliding shaft pendulum assembly 211 to swing by a certain range, so as to adjust the inclination angle of the bearing surface 101 on the bearing seat 12, thereby maintaining the bearing surface 101 parallel to the horizontal plane.

Optionally, when the bearing surface 101 is not parallel to the horizontal plane, a lower end 21102 of the swing rod 211 of the sliding shaft swing assembly 21 is driven to slide relative to the base 11, so as to drive the swing rod 211 to swing, thereby driving the bearing seat 12 to rotate by a certain angle, and adjusting the bearing surface 101 to return to the horizontal direction again.

Further optionally, the method for adjusting the bearing surface level of the supporting tool comprises the steps of:

the lower end 21101 of the swing lever 211 that drives the sliding axis swing assembly 21 slides in two non-collinear directions.

Further optionally, the method for adjusting the bearing surface level of the supporting tool comprises the following steps:

monitoring whether the space height of the bearing surface 101 changes, namely whether the absolute altitude of the bearing surface changes; and

when the space height of the bearing surface 101 changes, the bearing surface is returned to the original height by driving the bearing seat 12 to move up and down.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished.
