Of course, in other embodiments, the cart 200 may have other functions, such as providing a battery to power and charge the ultrasound host 100.

Referring to fig. 2, the display module 110 has a first housing 111 and a display screen assembly (not shown) mounted on the first housing 111. The screen of the display screen component can only play a role of display, and can also have display and touch functions so as to realize touch operation of a user on the equipment. The display screen assembly may further include a display screen control unit to enable control of the screen. The display panel assembly and other components such as a connection cable are accommodated in the first housing 111, and a screen of the display panel assembly is exposed from the first housing 111. The display module 110 is an integral module and can be integrally mounted to the main body 120 in the form of a module.

The host body 120 has a second housing 121 and a main control unit (not shown in the drawings). The main control unit is disposed in the second housing 121, and the main control unit is electrically connected to the display screen assembly, for example, the display screen control unit. The main control unit can be used as a main control part of the whole ultrasonic equipment to complete functions of data receiving, processing, sending and the like. Of course, the host body 120 may also have other components, such as a battery, an ultrasound probe interface, a data interface, a communication unit, etc., which may be provided within the second housing 121 or on the second housing 121.

Referring to fig. 2, in the embodiment, the first housing 111 and the second housing 121 enclose a mounting cavity, which may be closed or may have a certain degree of opening. The connection assembly 130 is received in the mounting cavity. Even, the components such as the connection cable between the display module 110 and the host main body 120 can be also accommodated in the installation cavity, so that the display module 110 and the host main body 120 are integrated integrally, the exposure of the internal structure is avoided, the appearance simplicity of the ultrasonic host 100 is improved, and the protection of the components such as the internal connection assembly 130 and the connection cable is facilitated.

Of course, in other embodiments, the display module 110 and the host body 120 may be disposed in an open manner, so as to expose the connecting component 130 and other structures between the display module 110 and the host body 120.

Further, in order to enable the display module 110 to have more flexible position change to meet more requirements of users, at least one of the display module 110 and the connecting assembly 130, the connecting assembly 130 and the host body 120, and the connecting assembly 130 has a kinematic pair, so that the display module 110 can move relative to the host body 120.

Further, in one embodiment, at least one of the kinematic pairs is a rotational pair, and the rotational pair is used to enable the display module 110 to rotate relative to the main body 120. The rotation center line of the display module 110 can be flexibly set according to application scenarios and requirements, for example, the rotation center line can be set in a horizontal direction, a vertical direction or an inclined direction. For example, in the embodiment shown in fig. 2, the rotation center line a of the display module 110 is arranged along the horizontal direction, so that the display module 110 shown in fig. 2 can rotate 90 ° from the landscape state shown in fig. 2 to switch to the portrait state to meet different display requirements and viewing requirements.

Referring to fig. 2, in this embodiment, the rotation center line a of the revolute pair is perpendicular to the screen of the display panel assembly, so that the display panel assembly can revolve around the rotation center line a (indicated by the rotation direction arrow B). During the rotation of the display module 110, the orientation of the screen can be ensured to be consistent and always face the user. Of course, in other embodiments, the rotation center line a of the rotation pair may have other angles with the screen of the display screen assembly, which can be flexibly selected according to the actual requirements for the screen orientation.

Further, referring to fig. 3-4 and fig. 6-7, in order to realize the above-mentioned revolute pair, the present application provides two different embodiments, in which the connecting assembly 130 has a connecting seat 131 and a revolute seat 132, and the revolute seat 132 and the connecting seat 131 are rotationally connected to form a revolute pair. The connecting base 131 is connected to the main body 120, and the rotating base 132 is connected to the display module 110. When the rotary base 132 rotates relative to the connecting base 131, the display module 110 rotates together with the rotary base 132.

The rotating base 132 has a first rotating matching portion, and the connecting base 131 has a second rotating matching portion, and the first rotating matching portion and the second rotating matching portion are rotatably connected. For example, in one embodiment, the first rotating engagement portion is a protruding shaft and the second rotating engagement portion is a shaft hole. Or in another embodiment, the first rotating matching part is a shaft hole, and the second rotating matching part is a convex shaft. The connecting base 131 and the rotating base 132 are rotatably connected through the shaft hole matching between the shaft hole and the protruding shaft. Of course, in other embodiments, the first rotating fitting portion and the second rotating fitting portion may be connected in a rotating manner by other structures.

Referring to fig. 3-5 and 6-7, in these embodiments, the connecting base 131 has a shaft hole 1311, and the rotating base 132 has a protruding shaft 1312. The protruding shaft 1312 is inserted into the shaft hole 1311. The protruding shaft 1312 may be integrally formed with or fixedly connected to the other portion of the rotary base 132.

Specifically, in the embodiment shown in fig. 3-5, the rotary seat 132 is mounted on the display module 110 by a snap structure 1322, etc., and forms a fixed connection with the display module 110. The connecting base 131 is mounted on the host body 120, such as the second housing 121 or a supporting base fixedly connected to the second housing 121, through the positioning posts 1312 and the mounting holes 1313, and the connecting base 131 and the host body 120 form a fixedly connected whole after connection.

In the embodiment shown in fig. 6-7, the rotary seat 132 is mounted on the display module 110 by a snap structure 1322, etc., and forms a fixed connection with the display module 110. The connection base 131 is mounted on the host body 120, for example, the second housing 121 or a support base fixedly connected to the second housing 121, through the positioning posts 1312 and the mounting holes 1313, and the connection base 131 and the host body 120 form a fixedly connected whole after connection.

In order to achieve smoother rotation and reduce friction between the protruding shaft 1312 and the shaft hole 1311, referring to fig. 3-5 and fig. 6-7, in these embodiments, the protruding shaft 1312 is sleeved with a bushing 133. In order to better adapt to the matching between the protruding shaft 1312 and the shaft hole 1311 and reduce the installation difficulty, the circumferential side wall of the shaft sleeve 133 has an open slot 1331 penetrating along the length direction thereof, so that the shaft sleeve 133 is in a non-closed structure.

The shaft sleeve 133 is usually made of self-lubricating material such as POM, nylon, or tin bronze, or made of steel, and a self-lubricating coating or a woven layer is attached to the surface of the steel to support, absorb shock, resist wear, and smooth rotation.

Referring to fig. 3-5 and 6-7, in these embodiments, the protruding shaft 1312 is inserted into the shaft hole 1311. In order to axially position the protruding shaft 1312 with respect to the shaft hole 1311, a stopper 134 is disposed at one end of the protruding shaft 1312 passing through the shaft hole 1311, and the outer diameter of the stopper 134 is larger than the inner diameter of the shaft hole 1311, so that the protruding shaft 1312 is rotatably connected to the shaft hole 1311.

In the figure, the retainer 134 is a flange that can be fixed to an end surface of the protruding shaft 1312 by screws. Of course, in other embodiments, the position-limiting member 134 may be other structures capable of axially positioning the protruding shaft 1312.

In the embodiments shown in fig. 3-5 and 6-7, the installation process can be briefly described as follows:

the protruding shaft 1312 of the rotating base 132 is sleeved with the shaft sleeve 133, and is installed in the shaft hole 1311 of the connecting base 131, and then the limiting member 134 is installed, and then the screw 125 is used for axial fixing, so that the installation of the rotating base 132 and the connecting base 131 is completed, because only axial screw fixing connection is performed during installation, and the circumferential direction is not fixed, the rotating base 132 can rotate relative to the connecting base 131.

Further, in one embodiment, the rotation center line a of the protruding shaft 1312 and the shaft hole 1311 can pass through the center of gravity of the display module 110. The display module 110 is designed such that the center of gravity is located on the rotation center line a, and thus, the structure can substantially achieve self-balance during rotation. Of course, in other embodiments, the center line A of rotation of the protruding axis 1312 and the axial hole 1311 may be offset from the center of gravity of the display module 110.

To optimize the rotational operation experience while avoiding inadvertent touches that could result in undesired rotation of the display module 110, one embodiment may also add damping during rotation. For example, a damping member may be disposed between the rotating base 132 and the connecting base 131, and the damping member provides a frictional force for keeping the rotating base 132 and the connecting base 131 relatively stationary. The damping member can adopt various structures capable of providing balanced damping in the prior art.

Referring to fig. 3-5, in this embodiment, the damping member 136 is at least one. The damping member 136 is disposed on the rotary seat 132, and an outer end surface of the damping member 136 contacts the connection seat 131 or a friction pad 136 fixedly mounted on the connection seat 131 to provide a friction force for preventing the rotary seat 132 and the connection seat 131 from rotating relatively.

As shown in fig. 3-5, in this embodiment, the damping member 136 and the friction pad 136 are both annular bodies. The damper 136 is fitted around the protruding shaft 1312 so as to provide damping force at various positions circumferentially from the protruding shaft 1312.

For example, in the illustrated embodiment, the damping member 136 may be a sealing ring, and the friction pad 136 may be made of various materials and structures that facilitate providing a damping force. In one embodiment, the proper amount of compression of the seal ring may be determined experimentally, and the frictional force converted from the positive pressure due to the amount of compression of the seal ring may be controlled to a constant value, and the influence of manufacturing errors may cause fluctuations in the frictional force within an acceptable range.

Of course, in other embodiments, the damping element 136 may be an annular body, for example, the damping element 136 may be a single body structure such as a block or a bar, and the number of the damping elements 136 is more than one, and the damping element is disposed at a certain position on the circumferential outer side of the protruding shaft 1312, as long as the outer end surface of the damping element 136 can contact with the connection seat 131 or the friction pad fixedly mounted on the connection seat 131 when the rotation seat 132 rotates relative to the connection seat 131. In this case, the friction pad may be an annular body or an annular body. Preferably, the friction pad is still a ring-shaped body, and the friction pad is located on the motion track of the block or bar-shaped damper 136 so as to be always in contact with the block or bar-shaped damper 136.

In other embodiments, the damping members 136 may be located on the connection seat 131, and the outer end surfaces of the damping members 136 contact the rotation seat 132 or the friction pads 136 fixedly mounted on the rotation seat 132 to provide a friction force for preventing the rotation seat 132 and the connection seat 131 from rotating relatively.

As shown in fig. 3 to 5, in this embodiment, the connection holder 131 has a cavity 1323, the damping member 136 is fitted and fixed in the cavity 1323, and the outer end of the damping member 136 protrudes from the cavity 1323. Of course, in other embodiments, the rotary seat 132 may also have a cavity 1323 for installing the corresponding damping member 136.

In addition, the damping member 136 may be fixed to the connection seat 131 or the rotation seat 132 by other methods, such as bonding, pressing, welding, clipping, etc.

Further, the number of the damping members 136 may be one or more. In particular, the number of damping members 136 may be selected according to the amount of damping force that needs to be provided.

In the example shown in fig. 3-5, the cavity 1323 has at least two turns, and the cavities 1323 are arranged annularly from inside to outside, i.e., sequentially from inside to outside in the radial direction of the protruding shaft 1312 (or the shaft hole 1311). The damping member 136 is correspondingly disposed in each ring of the cavity 1323. In the embodiment of fig. 3-5, the damping member 136 is annular, and thus the corresponding cavity 1323 also has an annular configuration to receive the damping member 136. In other embodiments, when the damping member 136 is one or more blocks or strips, the cavity 1323 may be non-annular, such as individual dimples. Of course, when the number of the dimples is plural, it may be provided in one or more turns around the outer circumference of the protruding shaft 1312 (or the shaft hole 1311), wherein one or more dimples may be provided in each turn.

Referring to fig. 6 and 7, another damper 136 structure is employed in this embodiment. The side wall of the shaft hole 1311 of the connecting base 131 is provided with a mounting hole 1316, the damping member 136 is mounted in the mounting hole 1316, and one end of the damping member 136 contacts the protruding shaft 1312 to provide a frictional force for preventing the protruding shaft 1312 and the shaft hole 1311 from rotating relatively. In this embodiment, the damping force is provided by the damping member 136 abutting the protruding shaft 1312. In other embodiments, one end of the damping member 136 may also contact a friction pad or other structure fixedly mounted on the protruding shaft 1312, providing a damping force by the damping member 136 abutting the friction pad or other structure on the protruding shaft 1312. The friction pad may be formed of various materials and structures that facilitate providing the damping force.

In the embodiment shown in fig. 6 and 7, the damping member 136 and the mounting hole 1316 are disposed radially of the axial bore 1311. In other embodiments, the damping member 136 and mounting hole 1316 may be oriented in other directions, such as obliquely with respect to the radial direction of the axial bore 1311.

Considering that the protruding shaft 1312 or the friction pad on the protruding shaft 1312 has a rotation requirement, referring to fig. 6 and 7, the damping member 136 has an arc surface 1351 capable of fitting the outer peripheral surface of the protruding shaft 1312 or the outer wall of the friction pad to increase the contact area between the damping member 136 and the protruding shaft 1312 or the friction pad, thereby providing a better damping force.

The damping member 136 may be fixedly mounted in the mounting cavity or may be resiliently coupled to the mounting cavity. Referring to fig. 6 and 7, the embodiment further includes an elastic member 137, and the elastic member 137 provides an elastic force for driving the damping member 136 against the protruding shaft 1312 or the friction pad. The elastic member 137 may be directly connected to the damper 136, or indirectly act on the damper 136 through other components to provide a restoring force (elastic force) against the protruding shaft 1312 or the friction pad to the damper 136.

Of course, in order to adjust the damping effect of the display module 110 relative to the host body 120 more conveniently according to the requirement, the damping can be adjusted conveniently through the structural design. For example, referring to fig. 6 and 7, the embodiment further includes a screw member 138, the screw member 138 abuts against the elastic member 137, the screw member 138 is screwed with the hole wall of the mounting hole 1316, and the compression amount of the elastic member 137, and thus the pressure applied to the protruding shaft 1312 by the damping member 136, is adjusted by screwing the screw member 138. In other embodiments, the screw member 138 may be engaged with the elastic member 137 in other manners.

Referring to the embodiment shown in fig. 3-5 and fig. 6-7, the position-limiting member 134 has a position-limiting portion 1341 protruding outward along a radial direction thereof, a position-limiting groove 1314 (or other position-limiting region) corresponding to the position-limiting portion 1341 is disposed on the connecting seat 131 (or the rotating seat 132) having the shaft hole 1311, and the position-limiting portion 1341 is disposed in the position-limiting groove 1314 and is limited to move in the position-limiting groove 1314. When the limiting member 134 rotates along with the protruding shaft 1312, the slot walls at both ends of the limiting slot 1314 are the limiting positions for the limiting portion 1341 to rotate towards both ends, thereby limiting the rotation angles of the limiting member 134 and the protruding shaft 1312.

Of course, in other embodiments, the position limiting portion 1341 may be disposed on the protruding shaft 1312 or the rotating base 132 (or the connecting base 131) on which the protruding shaft 1312 is disposed.

Further, referring to fig. 1, in this embodiment, the ultrasound apparatus further includes a floating arm 300. The floating arm 300 is mounted on the trolley 200, for example on the support column 210 of the trolley 200. The host body 120 is mounted on the floating arm 300. At least one of between the floating arm 300 and the cart 200, between the main body 120 and the floating arm 300, and inside the floating arm 300 has a kinematic pair so that the main body 120 can move in a horizontal direction, a vertical direction, or a three-dimensional space with respect to the cart 200.
