[0037] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0038] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0039] This embodiment provides an ultrasound device, such as a medical ultrasound device, which uses ultrasound signals to detect a patient and form an image.

[0040] Please refer to Figures 1 to 7 In one embodiment, the ultrasonic device includes a base 100, a control panel 200, a display device 300 and a floating device 400. Of course, in other embodiments, other related components may also be included. This embodiment mainly introduces components related to the floating function, and other related components can refer to the prior art.

[0041] The base 100 serves as a supporting structure for the ultrasonic device, and the base 100 may be located at the bottom of the entire device or at other locations. The base 100 may be provided with components such as a host and a power supply. In some embodiments, the base 100 may be provided with casters to facilitate the movement of the ultrasonic device. Of course, in some embodiments, in addition to the supporting function, the base 100 may also have other functions. For example, a storage basket may be provided on the base 100 to place some items. A handle may also be provided to push the device to move, etc.

[0042] The control panel 200 is mounted on the base 100. The control panel 200 is generally provided with buttons, knobs or touch units, etc., and the user can operate the ultrasonic device through the control panel 200. The display device 300 is used to display information about the processing process, the results of the processing, or other information. The display device 300 can be mounted on the control panel 200 or the base 100. Figures 1 to 6 As shown, in this embodiment, the display device 300 is installed on the control panel 200 . In other embodiments, the display device 300 may be directly installed on the base 100 instead of being connected to the base 100 via the control panel 200 .

[0043] The floating device 400 is used to enable the display device 300 or the control panel 200 to move at least in one plane, for example, between multiple positions in a horizontal plane. Figure 2 , 3 , 5 and 7, in one embodiment, the floating device 400 includes a first connection seat 410, a second connection seat 420 and at least one chain transmission arm 430. The chain transmission arm 430 has at least two chain units 431, and these chain units 431 are movably connected to each other, so as to form a chain transmission structure through a plurality of small units. The first connection seat 410 and the second connection seat 420 are respectively used to directly or indirectly connect different objects, such as the base 100, the control panel 200 or the display device 300. Figure 1 As shown, in this embodiment, the first connection socket 410 is connected to the display device 300 , and the second connection socket 420 is connected to the control panel 200 .

[0044] This embodiment also provides another ultrasonic device, such as another medical ultrasonic device. The ultrasonic device includes a base 100, a touch display device and a floating device 400. The base 100 and the touch display device are connected by a floating device 400. For example, the floating device 400 is directly or indirectly connected to the touch display device through a first connection seat 410, and the floating device 400 is directly or indirectly connected to the base 100 through a second connection seat 420. Of course, in other embodiments, the positions of the first connection seat 410 and the second connection seat 420 can also be interchanged. The difference between the ultrasonic device and the ultrasonic device shown in the above embodiment is that the touch display device replaces the display device 300 and the control panel 200 in the above ultrasonic device. For example, in one embodiment, the touch display device has a touch screen and other related components. The touch screen is used to display information and input commands, such as displaying images obtained by the ultrasonic probe and inputting parameter commands to control the operation of the ultrasonic probe, etc., and the operation is simple. The touch display device combines the original display device 300 and the control panel 200 into one, which is convenient for disinfection, has a small body, occupies a small space, is not restricted by hospital sites, is convenient for after-sales transportation, and further reduces the volume of the entire device. The touch display device cooperates with the floating device 400 to realize multi-position movement, thereby enriching the change position of the touch display device, facilitating the operator to use, and enabling the operator to more easily view and operate the touch display device.

[0045] Regardless of the ultrasound device used, please refer to Figure 2 , 3 , 5 and 7, in one embodiment, the chain unit 431 has a main body 4311. The main body 4311 is provided with a first mounting portion 4312 and a second mounting portion 4313 opposite to the first mounting portion 4312. All chain units 431 in a chain transmission arm 430 are connected in series, and the first mounting portion 4312 of one chain unit 431 in adjacent chain units 431 is rotatably connected to the second mounting portion 4313 of another chain unit 431. The chain unit 431 located at the outermost side (e.g., the front end or the rear end) of one end of the chain transmission arm is rotatably connected to the first connecting seat 410 ( Figure 1-11 The chain unit 431 at the outermost end (e.g., the rearmost end or the frontmost end) of the other end of the chain transmission arm is rotatably connected to the second connection seat 420 ( Figure 1-11 The rearmost chain unit is shown to be connected to the second connection seat 410), and can be rotatably connected to the second connection seat 420 through the second mounting portion 4313. The front and rear positions shown in this embodiment are only for the purpose of clearly describing these chain units. In other embodiments, the front and rear positions shown in this embodiment can also be reversed.

[0046] The first mounting portion 4312 of each chain unit 431 may have the same structure or different structures according to the actual assembly structure. Similarly, the second mounting portion 4313 of each chain unit 431 may have the same structure or different structures according to the actual assembly structure.

[0047] In addition to being connected to the corresponding object through the first connection seat 410 and the second connection seat 420, in some embodiments, the chain transmission arm 430 can also be directly connected to the assembly object by the chain unit located at the outermost end of one end of the chain transmission arm and the chain unit located at the outermost end of the other end of the chain transmission arm. For example, the chain unit located at the outermost end of one end of the chain transmission arm is used to connect with the display device 300, the control panel 200 or the display touch device, so that the chain transmission arm 430 can move with the display device 300, the control panel 200 or the display touch device. The chain unit located at the outermost end of the other end of the chain transmission arm is used to directly connect with the support structure such as the base 100, the control panel 200 (when the display device 300 is installed on the control panel 200, the control panel 200 can serve as the support structure of the chain transmission arm 430). The direct connection between the chain transmission arm 430 and each assembly object can be a fixed connection and a movable connection, and the movable connection is not limited to a rotational connection.

[0048] The above-mentioned various rotational connections (including the rotational connection between the chain units 431, the rotational connection between the chain unit 431 and the first connection seat 410 and the second connection seat 420, and the rotational connection when the chain transmission arm 430 is directly connected to each assembly object) can be realized by shaft hole matching rotation, bearing rotation, magnetic rotation or electric rotation. Figure 3 As shown, in one embodiment, the first mounting portion 4312 and the second mounting portion 4313 are rotatably connected via a rotating shaft 440 and a corresponding shaft hole.

[0049] In some embodiments, a damping mechanism may be provided in the rotating connection structure so that the rotating parts can stay in the required position more stably. For example, an elastic medium such as plastic, rubber or silicone is added between the shaft holes to increase the resistance.

[0050] In the above embodiment, the floating device 400 realizes floating at multiple positions by superposition of relative motion between the chain units 431 and relative motion between the chain units 431 and the first connection seat 410 and the second connection seat 420. The structural linkage has good flexibility and is easy to operate. Moreover, with the same number of motion joints, the device is smaller in size and simpler in structure, which can reduce the cost of the device. In particular, when there are more chain units 431, each two adjacent chain units 431 can rotate relative to each other, and all chain units 431 can form rich changes, thereby providing more floating changes.

[0051] The rotation axis between the adjacent chain units 431 is the first axis, the rotation axis between the outermost chain unit 431 at one end of the chain transmission arm and the first connection seat 410 is the second axis, and the rotation axis between the outermost chain unit 431 at the other end of the chain transmission arm and the second connection seat 420 is the third axis. In one embodiment, the first axis, the second axis and the third axis are parallel, so that the first connection seat 410 can move at different positions in the same plane relative to the second connection seat 420. Of course, in some embodiments, the first axis, the second axis and the third axis may also partially or completely intersect rather than be parallel, so that the first connection seat 410 can move at different positions in multiple planes relative to the second connection seat 420.

[0052] Please refer to Figure 3 and 5 In one embodiment, the first axis, the second axis and the third axis are perpendicular to the horizontal plane. Therefore, the first connection base 410 can move relative to the second connection base 420 at different positions in the horizontal plane, and the movement of the horizontal plane can better fit the user's usage habits.

[0053] Furthermore, the first mounting portion 4312, the main body 4311 and the second mounting portion 4313 may be an integrally formed structure, or may be separate components fixed together by a fixed connection. The shapes of the first mounting portion 4312, the main body 4311 and the second mounting portion 4313 may be flexibly set to ensure that the main body 4311 does not hinder the rotational connection between the first mounting portion 4312 and the second mounting portion 4313 within a certain angle.

[0054] For further information, please refer to Figure 3 and 5 In one embodiment, the first mounting portion 4312 is protruded on the main body 4311. Preferably, the first mounting portion 4312 is protruded horizontally on the side wall of the main body 4311. Therefore, a certain space can be reserved between the first mounting portion 4312 and the main body 4311 to allow adjacent chain units 431 to rotate at a certain angle.

[0055] like Figure 3 , 5 As shown in Figures 7 and 8, the outer wall of the first mounting portion 4312 forms an angle a with the outer wall of the main body 4311. Of course, the angle a can be an acute angle, a right angle, an obtuse angle or a larger angle. In one embodiment, the value of the angle a is: a≤180. In this way, the adjacent chain units 431 can rotate at a larger angle, thereby increasing the rotation angle between the adjacent chain units 431, and further increasing the floating range of the entire chain transmission arm. Please refer to Figure 5When the angle a is 180°, the outer wall of the first mounting portion 4312 is flush with the outer wall of the main body 4311 .

[0056] Please continue to refer to Figure 3 , 5 and 7. In one embodiment, the second mounting portion 4313 is a sunken platform located on one side of the main body 4311, and the top wall of the sunken platform is lower than the top wall of the main body 4311 to form a sunken cavity. When adjacent chain units 431 are assembled together, the first mounting portion 4312 of the rear chain unit 431 can be fully or partially accommodated in the sunken cavity of the front chain unit 431, so that the overall assembly height of the two chain units 431 is relatively small, reducing the volume of the chain transmission arm.

[0057] In other embodiments, adjacent chain units 431 may be rotationally connected via other rotating structures. For example, the second mounting portion 4313 is also protrudingly disposed on one side of the main body 4311, and the first mounting portion 4312 of the rear chain unit 431 extends above or below the second mounting portion 4313 of the front chain unit 431, forming a stacked structure with the second mounting portion 4313.

[0058] Furthermore, in order to improve the stability of the rotation connection, as Figure 3 , 5 As shown in Figures 7 and 8, in one embodiment, there are two first mounting parts 4312, and the two first mounting parts 4312 are symmetrically arranged on the upper and lower sides of the main body 4311. The upper and lower sides of the sinking platform form a sinking cavity with the main body 4311, and the two first mounting parts 4312 are located in two corresponding sinking cavities of another chain unit 431, that is, the second mounting part 4313 is inserted into the area between the two first mounting parts 4312, so that two rotation connection points are formed on the upper and lower sides of the second mounting part 4313, respectively. The two rotation connection points work together to make the first mounting part 4312 and the second mounting part 4313 rotate more stably and smoothly.

[0059] The first mounting portion 4312 has an arc-shaped outer wall, and correspondingly, the second mounting portion 4313 has an arc-shaped inner concave surface corresponding to the arc-shaped outer wall. When the first mounting portion 4312 is mounted on the second mounting portion 4313, the arc-shaped outer wall and the arc-shaped inner concave surface are opposite, so that the first mounting portion 4312 can be mounted on the second mounting portion 4313 and can rotate smoothly.

[0060] like Figures 1 to 3 As shown, the chain transmission arm 430 is one, and the display device 300, the control panel 200 or the touch display device can be moved between multiple positions through the floating function of the chain transmission arm 430.

[0061] In one embodiment, there are at least two chain transmission arms 430, so that the display device 300, the control panel 200 or the touch display device is supported by the combined floating effect of the at least two chain transmission arms 430. Figure 4 As shown, in one embodiment, there are two chain transmission arms 430, and the two chain transmission arms 430 are arranged side by side, and both ends of all chain transmission arms 430 are rotatably connected to the first connection seat 410 and the second connection seat 420 respectively. Preferably, the rotation axes between different chain transmission arms 430 and the first connection seat 410 coincide or are parallel; and / or the rotation axes between different chain transmission arms 430 and the second connection seat 420 coincide or are parallel. It should be noted that the "parallel" involved in this application can be understood as approximately parallel or completely parallel, and no specific limitation is made here.

[0062] In terms of force, the two chain transmission arms 430 can share the gravity of the display device 300, the control panel 200 or the touch display device, preventing the center of gravity of the entire device from shifting and becoming unstable. At the same time, when the display device 300, the control panel 200 or the touch display device is moved, the two chain transmission arms 430 restrain and cooperate with each other, making the movement of the display device 300, the control panel 200 or the touch display device more stable and smooth.

[0063] Furthermore, in order to increase the floating position of the floating device 400, for example, to increase the spatial change, in one embodiment, a third connecting seat is further included, and the second connecting seat 420 is connected to the third connecting seat in a structure capable of being lifted and lowered relative to the third connecting seat.

[0064] Among them, the lifting function is realized between the second connecting seat 420 and the third connecting seat through a guide rail sliding structure, a pulley slide rail structure, a pulley groove rail structure, a linear guide sleeve structure, a screw and lead screw structure, a sprocket chain transmission structure, a synchronous belt pulley transmission structure, a pulley rope transmission structure, a gear rack transmission structure or a connecting rod transmission structure.

[0065] Please refer to Figure 6 and 7 In one embodiment, the second connection base 420 and the third connection base 450 are connected by two connecting rods 460. The second connection base 420, the third connection base 450 and the two connecting rods 460 form a parallelogram mechanism. The third connection base 450 can be used to connect the base 100, the control panel 200, the display device 300 or the touch display device. The parallelogram mechanism enables the second connection base 420 to be lifted and lowered relative to the third connection base 450.

[0066] Please refer to Figure 8 and 9In one embodiment, a parallelogram mechanism is formed between the second connecting seat 420 and the third connecting seat 450 through two connecting rods (a first connecting rod 461 and a second connecting rod 462). At the same time, a damping mechanism is also added to the parallelogram mechanism to enable the second connecting seat 420 to stay at a desired position relative to the third connecting seat 450.

[0067] Specifically, please refer to Figure 8 and 9 In one embodiment, one end of the first connecting rod 461 is connected to the third connecting seat 450 through a rotating pair A1, and the other end is connected to the second connecting seat 420 through a rotating pair A2; one end of the second connecting rod 462 is connected to the third connecting seat 450 through a rotating pair A3, and the other end is connected to the second connecting seat 420 through a rotating pair A4. The connection between the first connecting rod 461 and the third connecting seat 450 and the second connecting seat 420 and the connection between the second connecting rod 462 and the third connecting seat 450 and the second connecting seat 420 are both rotating pair connections, and the first connecting rod 461 and the second connecting rod 462 can rotate relative to the third connecting seat 450. The positions of the rotating pairs are roughly in a parallelogram, and the four rotating pairs are at the four vertices of the parallelogram. The first connecting rod 461 is roughly parallel to the second connecting rod 462. The chain transmission arm 430 is connected to the second connecting seat 420.

[0068] The damping mechanism includes a spring 463, a slider assembly 464 and two damping connecting rods 465. The slider assembly 464 and the spring 463 are mounted on the first connecting rod 461. The first connecting rod 461 not only has the function of forming a four-link, but also has the function of generating damping when the slider assembly 464 slides on it. One end of the damping connecting rod 465 is connected to the first connecting rod 461 through a rotating pair, and the other end is connected to the third connecting seat 450 through a rotating pair.

[0069] In this embodiment, the slider assembly 464 includes a bracket 4641 and a friction pad 4642. The assembly process is as follows: after the first connecting rod 461 passes through the spring 463 and the bracket 4641 in the slider assembly 464, one end of the first connecting rod 461 is connected to the second connecting seat 420 through the rotating pair A2, and the other end of the first connecting rod 461 is connected to the third connecting seat 450 through the rotating pair A1, and the friction pad 4642 is arranged at the part of the first connecting rod 461 located in the bracket 4641; then two damping connecting rods 465 are arranged on both sides of the bracket 4641, and one end of the damping connecting rod 465 is rotationally connected to the bracket 4641, and the other end is rotationally connected to the third connecting seat 450.

[0070] The spring 463 can be a metal spring, such as a compression spring, and the first connecting rod 461 passes axially through the middle of the spring 463. One end surface of the spring 463 abuts against the first connecting rod 461, such as a flange provided on the first connecting rod 461, and the other end surface abuts against the bracket 4641.

[0071] Taking the spring 463 as a compression spring as an example, the spring 463 generates a thrust on the first connecting rod 461. Of course, the first connecting rod 461 can also be provided with a thread, the thread is connected to an adjusting nut, and the spring 463 abuts on the adjusting nut. Therefore, by turning the adjusting nut, the distance between the nut and the other end can be adjusted, that is, the compression amount of the spring 463 can be adjusted, so that the magnitude of the thrust generated by the spring 463 can be adjusted.

[0072] In addition, one end of the spring 463 may also directly abut against the second connecting seat 420 without providing a flange structure on the first connecting rod 461 . In this case, the force of the spring 463 directly acts on the slider assembly 464 and the second connecting seat 420 .

[0073] The spring 463 may not be sleeved outside the first connecting rod 461, but may be separately arranged from the first connecting rod 461. However, when the spring 463 is sleeved outside the first connecting rod 461, the structure is more compact and occupies less space.

[0074] Please refer to Fig.10 In another embodiment, the second connecting seat 420 and the third connecting seat 450 form a vertical lifting structure, wherein the second connecting seat 420 serves as an inner column block and the third connecting seat 450 serves as an outer column block, wherein the inner column block can be lifted and lowered relative to the outer column block, thereby realizing the lifting function.

[0075] On the other hand, in one embodiment, a fourth connection base 470 is further included, and the fourth connection base 470 is connected to the first connection base 410 in a structure capable of being lifted and lowered relative to the first connection base 410. Thus, the fourth connection base 470 and a device connected to the fourth connection base 470 (such as the base 100, the control panel 200, the display device 300 or the touch display device) can be lifted and lowered relative to the first connection base 410.

[0076] Similarly, the lifting function is realized between the fourth connecting seat 470 and the first connecting seat 410 through a guide rail sliding structure, a pulley slide rail structure, a pulley groove rail structure, a linear guide sleeve structure, a screw and lead screw structure, a sprocket chain transmission structure, a synchronous belt pulley transmission structure, a pulley rope transmission structure, a gear rack transmission structure or a connecting rod transmission structure.

[0077] Specifically, please refer to Fig.11In one embodiment, the lifting structure includes a lifting bracket 471, a constant force spring 472, a lifting slide block 473 and a lifting shell 474. The fixed end 4721 of the constant force spring 472 is fixed to the lifting bracket 471, the moving end 4722 of the constant force spring 472 is fixed to the support shaft 4731 of the lifting slide block 473, the lifting shell 474 is fixed to the lifting bracket 471, and the sliding end of the lifting slide block 473 is connected to the card slot 4711 of the lifting bracket 471 and can slide relatively. The lifting slide block 473 passes through the lifting shell 474 and is fixed to the fourth connecting seat 470, so as to realize the lifting of the fourth connecting seat 470 relative to the first connecting seat 410. Fig.10 The fourth connection base 470 is used to connect the display device 300. A damping shaft 310 can be arranged between the fourth connection base 470 and the display device 300 so that the display device 300 can stop at a desired position. Of course, the base 100, the control panel 200, the base 100 or the touch display device can also be connected.
