Abstract

A floating apparatus (3) and an ultrasonic device. A first moving member (33) and a second moving member (34) are configured to reciprocate in an arc-shaped or circular trajectory on a support member (31). Meanwhile, both ends of lift arms (35, 36) are hingedly connected to moving members (33, 34) and a connection base (39), respectively. When a user applies force to the connection base (39) or the lift arms (35, 36), the positions of the first moving member (33) and the second moving member (34) on the support member (31) can be changed, so that the first moving member (33) and the second moving member (34) are distant from and get close to each other on the support member (31) according to the stress in the arc-shaped or circular trajectory. Meanwhile, the angle between the lift arms (35, 36) and the connection base (39), and the moving members (33, 34) can also be changed according to the stress, so that multi-position movement and rotation is achieved for the connection base (39) in a plane. Meanwhile, the lift arms (35, 36) have the lift function, so that the spatial floating in horizontal and vertical directions can be achieved by combining other components. The structure is more simplified while achieving multi-azimuth floating in horizontal and vertical directions, and improves the compactness of the apparatus, and the linkage flexibility is better.

Description

Ultrasound equipment and floating devices

Technical field

The present application relates to an ultrasonic device, and in particular, to an ultrasonic device and a floating device thereof capable of achieving multi-directional movement.

Background technique

When medical personnel use medical instruments with display equipment (taking ultrasound diagnostic equipment as an example), they are often based on the needs of operation, diagnosis, and treatment, combined with the need for visual comfort of doctors of different heights, and require that the display can be adjusted during work. The positional relationship between the device and the operator's line of sight requires the display device to be able to move flexibly, that is, it can achieve operations such as up and down, back and forth, left and right, and left and right rotation (full floating operation), so that the display device can meet the operator's requirements. The intention can be freely adjusted for movement.

General desktop ultrasound diagnostic instruments can be divided into the following categories in terms of display device movement:

1. The display device does not have a space lifting function, and is generally composed of two flat links articulated through the head and tail joints, and only has a floating operation function in the plane. This method has a single function and simplified castration.

2. The space lifting function of the display device is generally realized by a flat link and a head-to-tail joint of a support arm with a lifting function. This structure satisfies the function of articulated rotating joints, and changes in damping force values of different joints will cause very large differences in in-plane motion experience. There are too many turning joints, and the structure and operation are more complicated.

3. A simplified five-link system is used to form a closed system. Two links are support arms with a lifting function, and the remaining three are flat links. The head and tail joints between the links are hinged to realize the movement of the display device in the space. This structure reduces the dependence on the joint force value of multiple joints, and can achieve a stable sports experience. However, it involves multiple connecting rods and the rotating hinge between the connecting rods, which has many parts, has a complicated structure, and has a complicated assembly cost.

The terms “connection” and “connection” in this application include direct and indirect connections (connections) unless otherwise specified.

This embodiment provides an ultrasound device, which may be, for example, an ultrasound diagnostic apparatus or other ultrasound equipment.

Please refer to FIGS. 1 and 2. In one embodiment, the ultrasound apparatus includes a control panel 1, a display device 2, a floating device 3, and a host 9. The display device 2 may use various display devices for displaying various images or other electronic information, such as information for displaying a processing process, a result of processing completion, or other information. The display device 2 may be a display screen or a touch display device with a touch function. The control panel 1 is generally provided with keys, knobs and the like, and the user can operate the ultrasound diagnostic apparatus through the control panel 1. In this embodiment, the control panel 1 is mounted on the host computer 9, and the display device 2 is mounted on the control panel 1. The ultrasonic device may also be configured with components such as a wheel and a handle, which are not repeated here.

The floating device 3 has a space floating function and can be used to switch the display device 2 between positions in the space. Please refer to FIGS. 3 and 4. The floating device 3 includes a support member 31, a moving member, a lifting arm, and a connection base 39.

The moving member includes a first moving member 33 and a second moving member 34. The first moving member 33 and the second moving member 34 are mounted on the supporting member 31 in such a manner as to be capable of reciprocating movement along the arc or circular trajectory on the supporting member 31. The first moving member 33 and the second moving member 34 may reciprocate along the same arc or circular track. When the first moving member 33 and the second moving member 34 are subjected to an external force, they can make a reciprocating motion along the support member 31.

The lifting arm includes a first lifting arm 35 and a second lifting arm 36. The first lifting arm 35 and the second lifting arm 36 each have a first end and a second end capable of being raised and lowered relative to the first end. The first end of the first lifting arm 35 is mounted on the first moving member 33 and can rotate relative to the first moving member 33 about a first rotation axis. A first end of the second lifting arm 36 is mounted on the second moving member 34 and can rotate relative to the second moving member 34 about a second rotation axis. In this way, the first lifting arm 35 and the second lifting arm 36 can rotate around the first moving member 33 and the second moving member 34, respectively, and the rotation angles can also be different.

The second end of the first lifting arm 35 is connected to the connecting base 39 and can rotate relative to the connecting base 39 about a third rotation axis. The second end of the second lifting arm 36 is connected to the connecting base 39 and can rotate relative to the connecting base 39 about a fourth rotation axis. That is, the first end and the second end of the lifting arm are rotatably connected to the connecting member and the connecting base 39, respectively. The connecting base 39 can be moved in the horizontal and vertical directions by the lifting arm and the moving member. The support 31 of the floating device 3 is fixedly mounted on the control panel 1, and the connecting base 39 of the floating device 3 is connected to the display device 2, so that the display device 2 can be spatially displaced from the control panel 1 through the floating device 3.

In addition, in some other embodiments, the supporting member 31 of the floating device 3 may also be fixedly mounted on the host computer 9, so that the display device 2 may perform a spatial floating displacement relative to the host computer 9 instead of the control panel 1 through the floating device 3.

Please refer to FIGS. 5-8. Since the first moving member 33 and the second moving member 34 are configured to perform an arc or a circular trajectory on the support member, at the same time, the two ends of the lifting arm are respectively connected to the moving member and the connecting seat. 39 hinge, so when the user applies force to the connecting base 39 or the lifting arm, the position of the first moving member 33 and the second moving member 34 on the supporting member 31 can be changed, so that the first moving member 33 and the second moving member 34 can move away from and approach each other along the arc or circular trajectory on the support according to the force. At the same time, the angle between the lifting arm and the connecting base 39 and the moving part can also change by itself according to the force, so that the connecting base 39 can realize multi-position movement and rotation in the plane. At the same time, the lifting arm itself has a lifting function, and in combination with other components, the connection base 39 and the components (such as the display device 2) installed on the connection base 39 can float in the horizontal and vertical directions, including left and right. Move, move up and down, move forward and backward, and rotate. This structure has a more simplified structure while achieving multi-directional floating in the horizontal and vertical directions at the same time, with lower cost and convenient maintenance. Moreover, the overall structure can be modularized, which can improve the compactness of the device, fewer parts, and better linkage flexibility.

The ultrasonic device adopts such a floating device 3, so that the display device 2 can be floated in multiple positions in the space, so that the display device 2 can be easily adjusted to a position adapted by the user. Moreover, the structure of the floating device 3 is more simplified and compact, which is beneficial to the miniaturization of the ultrasonic equipment. At the same time, the floating device 3 has good linkage flexibility and is more conducive to user operation. The floating device 3 has a larger operating range and can achieve more space for floating.

Of course, although this embodiment uses an ultrasonic device as an example, it should be noted that the floating device 3 can also be applied to other devices that need to realize space floating, and is not limited to the ultrasonic device.

Further, the first moving member 33 and the second moving member 34 are mounted on the supporting member 31 in a manner capable of reciprocating along the arc or circular trajectory on the supporting member 31, which can be achieved in various ways. For example, in one embodiment, the supporting member 31 has a curved or circular moving track, and the first moving member 33 and the second moving member 34 move on the moving track. Of course, in other embodiments, the support member 31 may not have a clear arc or circular moving track, but the movement direction of the moving member may be limited by a mechanical structure, so that the moving member can only follow the arc or Circular motion.

Please refer to FIG. 3 and FIG. 4. In one embodiment, the supporting member 31 has a circular slide rail, and the moving members (the first moving member 33 and the second moving member 34) are sliders. On a linear slide.

The above FIGS. 3 and 4 only show an example. The cooperation manner between the support member 31 and the moving member can be adopted but is not limited to the connection method of the slide rail and the slider, the connection method of the slide groove and the slider, the pulley and the slide rail. One of the connection modes, the rope form of the pulley and the transmission form of the connecting rod. Of course, not all structures capable of achieving linear reciprocating motion of the moving member relative to the support member 31 are not listed here. Structures not listed to achieve this purpose are still included in this application.

Preferably, in an embodiment, the first rotation axis and the second rotation axis are parallel to each other and simultaneously perpendicular to a plane on which the reciprocating direction of the moving member is located. In this way, when the display device 2 is adjusted, the first moving member 33 and the second moving member 34 can be easily driven to move on the supporting member 31.

Preferably, in an embodiment, the third rotation axis and the fourth rotation axis are parallel or coincide with each other. Please refer to FIGS. 3 and 4, the first lifting arm 35 and the second lifting arm 36 are rotatably connected to both ends of the connecting base 39 through

different shafts

395 and 396 respectively, so that the third rotation axis and the fourth rotation axis are parallel to each other. . In other embodiments, the first lifting arm 35 and the second lifting arm 36 may be coaxially mounted, so that the third rotation axis and the fourth rotation axis coincide. When the first lifting arm 35 and the second lifting arm 36 are coaxially mounted, the rotation angle of the connecting base 39 relative to the first lifting arm 35 and the second lifting arm 36 may be larger.

Preferably, in an embodiment, the first rotation axis and the second rotation axis are parallel to the third rotation axis and the fourth rotation axis. In this way, when a user applies a force to the floating device 3, the rotation movements of the rotation axes can be effectively matched, and interference between the movements can be avoided, so that the change of the floating device 3 can be smoother and more stable.

It should be noted that in this article, when referring to the two axes of rotation "perpendicular to each other", it can mean: when the two axes of rotation are in the same plane, the two are perpendicular to each other; when the two axes of rotation are not When in the same plane, the two are spatially perpendicular to each other, that is, the projection of one rotation axis on the plane where the other rotation axis is located is perpendicular to the other rotation axis.

In this article, when two axes of rotation "intersect" are mentioned, it can mean: when the two axes of rotation are in the same plane, they intersect each other; when the two axes of rotation are not in the same plane, where The projection of one rotation axis on the plane on which the other rotation axis lies and the other rotation axis intersect each other.

Further, the lifting arm is a connecting arm with a lifting function, and various structures can be applied to achieve the lifting function. For example, the lifting arm can use a parallelogram mechanism to achieve the lifting function.

Please refer to FIGS. 9 and 10, taking the first lifting arm 35 as an example. The first lifting arm 35 includes a fixing base 351, a sliding rod 354, a lifting base 359, and a lower bracket 358. The fixing base 351, the sliding rod 354, the lifting base 359, and the lower bracket 358 are sequentially rotatably connected to form a parallel four-link mechanism. When the lifting base 359 is moved, the position of the fixed base 351 remains unchanged, and the lifting base 359 generates a lifting motion.

The fixing base 351, the lifting base 359, the sliding rod 354, and the lower bracket 358 of the first lifting arm 35 form a parallel four-link structure through a pin 71, a pin 75, a pin 81, and a pin 85, which can ensure that the lifting seat 359 The function is always parallel to the fixed base 351 during the lifting process.

The fixing base 351 is rotatably connected to the first moving member 33, so that the first lifting arm 35 is rotatably connected to the first moving member 33. The lifting base 359 is rotatably connected to the connecting base 39, so that the first lifting arm 35 is rotatably connected to the connecting base 39.

Specifically, referring to FIG. 4, the fixing base 351 of the first lifting arm 35 is connected to the first moving member 33 and is rotatable about the rotation shaft 335. Similarly, the fixing seat 361 of the second lifting arm 36 is connected to the second moving member 34 and is rotatable about the rotating shaft 345. The lifting base 359 of the first lifting arm 35 is connected to the connecting base 39 through a rotating shaft 395 and is rotatable about the rotating shaft 395. Similarly, the lifting base 359 of the second lifting arm 36 is connected to the connecting base 39 through a rotating shaft 396 and is rotatable about the rotating shaft 396.

Of course, the above lifting structure is only an example, and at least one of the first lifting arm 35 and the second lifting arm 36 may adopt this structure. Or, both adopt other lifting structures to achieve the lifting function. For example, the lifting structure may also include, but is not limited to, the simplified parallel four-link form shown in this case, the traditional four-link system, the parallel four-link system, and the approximate parallel lifting of a chain or rope-driven single link.

Further, in order to ensure that the lifting arm can be stabilized at the current height at any time, so that the display device is stopped at any position during lifting, in one embodiment, at least one of the first lifting arm 35 and the second lifting arm 36 has a damping force balance. A mechanism for stabilizing the first lifting arm 35 and the second lifting arm 36 at a set height. Since the first lifting arm 35 and the second lifting arm 36 are connected to the connecting base 39 in common, when one of them is stabilized at a set height, the other cannot move.

The damping force balancing mechanism can take many forms, such as, but not limited to, a gas spring form, a tension spring form including a compression spring form, a constant force spring form such as a coil spring form, a torsion spring form, an internal friction damping structure, and the like.

Please refer to FIGS. 9 and 10. In one embodiment, the damping force balancing mechanism includes a compression spring 356 and a damping assembly 355. The damping component 355 and the compression spring 356 are sleeved on the connecting rod 354. The damping component 355 is connected to the fixing base 351 through a transmission rod 352, and two ends of the transmission rod 352 are rotatably connected to the damping component 355 and the fixing base 351, respectively. The rotation axis of the transmission rod 352 relative to the fixed base 351 is staggered from the rotation axis of the connecting rod 354 relative to the fixed base 351. The two ends of the compression spring 356 are compressed by the damping component 355 and the connecting rod 354, respectively. By designing, the load force value of the lifting base 359 can be kept constant during the lifting process, and the lifting arm has a certain damping force value, which can cause the display device 2 to stop stably at any position during the lifting process. The first connecting arm 35 may further be provided with an upper case 61 to cover an internal structure such as a compression spring 356.

For example, a damping assembly 355 may include a slider and a spring provided in the slider. The slider is sleeved on the connecting rod 354 and is connected to the fixing base 351 through the support connecting members on both sides. Both ends of the support connection member are rotatably connected to the slider and the fixing base 351, for example, the support connection member can be coaxially rotatably connected to the fixing base 351 with the lower bracket 358. The damping component 355 can form a damping force balance for the connecting rod 354, so that the connecting rod 354 stays in a required position stably.

Further, the parallel four-link mechanism has four fifth rotation axes (axis directions of the

pins

71, 75, 81, and 85) that are parallel to each other. The fifth rotation axis is perpendicular to the first rotation axis and the second rotation axis, and the fifth rotation axis and the linear reciprocating direction of the moving member are parallel to each other. In this way, the lifting movement of the lifting arm, the rotation of the lifting arm and the moving member, and the linear movement of the moving member and the support member 31 can form a more effective cooperation, so that the floating movement of the floating device 3 is smoother and more stable.

The fifth rotation axis, the third rotation axis, and the third rotation axis may also be perpendicular to each other, so that the lifting movement of the lifting arm and the rotation of the lifting arm and the connecting base 39 can form a more effective cooperation, so that the floating movement is smoother and more stable. .

In the above-mentioned parallel four-link mechanism, the lower bracket 358 can also be omitted, and the fixing base 351 and the lifting base 359 can be connected only by the connecting rod 354. In this case, a corresponding rotation stabilization mechanism such as a rotation damping device needs to be provided at the rotational connection of the connecting rod 354 and the lifting base 359 to ensure that the lifting base 359 can be stabilized at various angles relative to the connecting rod 354.

Of course, the above lifting structure is only an example, and at least one of the first connecting arm 35 and the second connecting arm 36 may adopt this structure.
