Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an articulating mechanism of a desktop ultrasound machine. The articulating mechanism 10, which may also be referred to as a latch-type actuator, may be coupled to the base and control panel, respectively, of the desktop ultrasound machine. As shown in fig. 1, the articulating mechanism 10 includes: the device comprises a pin shaft 11, a rotating table 12 and a supporting plate 13, wherein the pin shaft 11 is fixedly connected with the supporting plate 13, the supporting plate 13 is fixedly connected with a base of the desktop ultrasonic instrument, and the rotating table 12 is fixedly connected with a control panel of the desktop ultrasonic instrument so as to drive the control panel to move; the rotating table 12 has a plurality of through holes 121, and the rotating table 12 is movable relative to the support plate 13 in a direction parallel to the plate surface of the support plate 13. When the pin shaft 11 is inserted into the through hole 121 of the rotating table 12, the control panel is fixed at a certain position along with the rotating table 12; after the pin 11 is disengaged from the through hole 121, the control panel can rotate with the rotating table 12, and after the control panel reaches a desired position, the pin 11 is inserted into the through hole 121 again to fix the control panel.

However, the articulating mechanism 10 of the above desktop ultrasound machine has three problems:

1. the pin 11 of the movable connecting device 10 can only be inserted into the preset through hole 121, and in the positioning process, the control panel cannot be fixed at any position within the preset range, so that the flexibility of the movable connecting device 10 is poor.

2. The pin 11 and the through hole 121 in the movable connection device 10 have high requirements on the machining precision and the installation precision, if the through hole 121 is larger than the pin 11, the control panel is easy to rock when being fixed, and if the through hole 121 is smaller than the pin 11, the pin 11 is easy to be clamped in the through hole 121, which results in large manufacturing difficulty of the movable connection device 10.

3. In the transportation process of the movable connecting device 10, the generated vibration is easy to cause the pin shaft 11 and the through hole 121 to be blocked, so that the transportation and maintenance requirements of the desktop ultrasonic instrument are difficult.

The embodiment of the application provides a desktop ultrasonic instrument which can solve the problems existing in the related technology.

The embodiment of the application provides a desktop ultrasonic instrument, and the desktop ultrasonic instrument can include: the power supply assembly is used for supplying power to the movable connecting device.

The articulating mechanism 20 may include: a support plate 21, at least one first fixed component 22 (fig. 1 and 2 in the embodiment of the present application illustrate that the movable connecting device 20 includes two first fixed components 22, and the movable connecting device 20 also includes 1, 3 or more first fixed components 22, and the embodiment of the present application is not limited herein), a first connecting component 23 and a first movable plate 24.

The first fixing member 22 may include a first electromagnet 221 and a first bracket 222, and the first electromagnet 221 may be installed in the first bracket 222 and detachably connected to the first bracket 222.

The first connecting assembly 23 may be connected to both the first movable plate 24 and the support plate 21, and the first connecting assembly 23 may be used to fix the first movable plate 24 and the support plate 21 in a direction f1 perpendicular to the plate surface of the support plate 21. The support plate 21 and the first flap 24 are relatively movable in a direction parallel to the plate surface of the support plate 21 (a direction perpendicular to the paper surface in fig. 1). That is, the first connecting assembly 23 may be used to connect the first movable plate 24 and the support plate 21 on the one hand, and may be used to support the first movable plate 24 in the direction f1 on the other hand. The first movable plate 24 and the support plate 21 are spaced apart in the direction f1 to avoid the first movable plate 24 and the support plate 21 rubbing against each other during the relative movement.

It should be noted that, in the embodiment of the present application, the first movable plate 24 and the support plate 21 are fixed in the direction f1, which may not mean absolute fixation, and may further include that the first movable plate 24 and the support plate 21 have a small relative displacement in the direction f 1.

The first bracket 222 may be fixedly connected to one of the support plate 21 and the first movable plate 24, and the first electromagnet 221 is configured to extend from the first bracket 222 under the action of magnetic force and attract the other one of the support plate 21 and the first movable plate 24 for fixation.

Alternatively, the first fixing assembly 22 may be mounted on the first flap 24 and may be adsorbed with the support plate 21 to fix the first flap 24 and the support plate 21 in a direction parallel to the plate surface of the support plate 21.

Since the movable connection device 20 in the embodiment of the present application fixes the first movable plate 24 and the supporting plate 21 by using the magnetic force generated by the first electromagnet 221, that is, the first electromagnet 221 can be attracted to each position of the first movable plate or the supporting plate, so that the external structure connected to the first movable plate 24 can be fixed at each position within the preset range, compared with the related art in which the pin-type movable connection device can only be fixed at several preset positions, the movable connection device 20 in the embodiment of the present application does not need to set the attraction position of the first electromagnet 221 in advance, and the flexibility of the movable connection device 20 is higher.

In addition, the movable connecting device 20 in the embodiment of the present application is not provided with a bolt type fixing device, and the first electromagnet 221 and the first movable plate 24 or the supporting plate 21 are adsorbed therebetween, so that the phenomena of jamming or shaking and the like can be avoided to a great extent, and the manufacturing difficulty, the transportation difficulty and the maintenance difficulty of the movable connecting device 20 can be reduced.

The support plate 21 and the first movable plate 24 are used to be connected with two external structures, respectively, so that the two external structures can be relatively moved or fixed.

In summary, the present application provides a desktop ultrasound apparatus, including an active connection device and a power supply module, wherein the active connection device of the desktop ultrasound apparatus may include: the supporting plate, at least one first fixing component, a first connecting component and a first movable plate. Wherein, first fixed subassembly includes first electro-magnet and first support, and first magnet is installed in first support. First support and one fixed connection in backup pad and the first fly leaf, when the swing joint device needs to be fixed, first electro-magnet can stretch out from first support under the effect of magnetic force, and adsorb in order to fix backup pad and fly leaf with another in backup pad and the first fly leaf, and because first electro-magnet is through the fixed swing joint device of its magnetic force that produces, need not to set up the adsorption site of first electro-magnet in advance, this first electro-magnet can adsorb in each position of first fly leaf or backup pad, make the exterior structure that first fly leaf is connected can fix in each position, can solve the relatively poor problem of the flexibility of desk-top ultrasonic instrument in the correlation technique, the better effect of the flexibility of desk-top ultrasonic instrument has been reached.

For example, the supporting plate 21 may be fixedly connected to a base of the desktop ultrasound apparatus, the first movable plate 24 may be connected to a control panel of the desktop ultrasound apparatus, or the control panel of the desktop ultrasound apparatus may be integrally formed with the first movable plate 24.

Alternatively, as shown in fig. 2, the first bracket 222 may be fixedly connected to the first movable plate 24, the first bracket 222 may be connected to the first movable plate 24 by a bolt, or the first bracket 222 may be welded to the first movable plate 24. The first magnet 221 is connected to the first movable plate 24 through the first bracket 222, and the first magnet 221 may be attracted to the support plate 21 for fixing. Illustratively, the material of the support plate 21 may include pure iron (DT 4C).

The first fixing member 22 may further include a first elastic member 223, and one end of the first elastic member 223 is connected to the first electromagnet 221 and the other end is connected to the first bracket 222. The first elastic element 223 can separate the first electromagnet 221 from the support plate 21 when the first electromagnet 221 is not attached to the support plate 21, so as to prevent the first electromagnet 221 from rubbing against the support plate 21 when moving along with the first movable plate 24.

Optionally, as shown in fig. 4, fig. 4 is a schematic structural diagram of another movable connection device of a desktop ultrasound apparatus provided in the embodiment of the present application. The first fixing member of fig. 4 has the same structure as that of fig. 2. The first bracket 222 may have a through hole 2221, and the first elastic member 223 may include a pin 2231, a first spring 2232, and a split ring 2233.

In which one end s1 of the pin 2231 passes through the through hole 2221 to be connected to the first electromagnet 221 in the first bracket 222, the pin 2231 can move in a direction perpendicular to the plate surface of the support plate 21, and one end s1 of the pin 2231 can be welded or detachably connected to the first electromagnet 221. Illustratively, as shown in fig. 4, one end s1 of the pin 2231 has a first annular protrusion, and a side of the first electromagnet 221 adjacent to the pin 2231 also has a second annular protrusion, through which the pin 2231 and the first electromagnet 221 can overlap to mount the first electromagnet in the first bracket 222.

The split ring 2233 is fitted over the portion of the pin 2231 outside the first support 222 and is fixedly connected to the pin 2231. Circlip 2233 may be bolted or welded to pin 2231, and circlip 2233 may illustratively be bolted to pin 2231 to facilitate assembly of pin 2231, first support 222, and first spring 2232, to reduce the difficulty of manufacturing articulating mechanism 20, while facilitating maintenance of articulating mechanism 20.

One end of the first spring 2232 abuts against a side of the first bracket 222 away from the first electromagnet 221, and the other end abuts against the circlip 2233, and the first spring 2232 is in a compressed state when the first electromagnet 221 extends out of the first bracket 222. That is, in the process of the first electromagnet 221 being attracted to the support plate 21, the first magnet 221 drives the pin 2231 to move toward the direction close to the support plate 21, so that the first electromagnet 221 abuts against the support plate 21, at this time, the first spring 2232 sleeved on the pin 2231 is compressed by the circlip 2233, so that the first spring 2232 is in a compressed state, and then the first spring 2232 can apply a pulling force to the first electromagnet 221 in the direction away from the support plate 21, and the value of the pulling force can be smaller than the attraction force of the first electromagnet 221 to the support plate 21 and larger than the weight of the first magnet 221, so as to prevent the first electromagnet 221 and the support plate 21 from being separated by the first spring 2232 when the first electromagnet 221 is attracted to the support plate 21.

For example, the first electromagnet 221 may be a holding-cup type electromagnet, and a switch unit may be mounted on the first movable plate 24, and the switch unit may be electrically connected to the first electromagnet 221 to control power on or power off of the first electromagnet 221. The first electromagnet 221 may be attracted to the support plate 21 for fixing when the power is off, and when the power is on, the first electromagnet 221 loses its magnetic property, and the first spring 2232 displaces the first electromagnet 221 in a direction away from the support plate 21 by an elastic force, so that a certain gap is maintained between the first electromagnet 221 and the support plate 21. The first electromagnet 221 only needs to be electrified during the relative movement of the first movable plate 24 and the support plate 21, and does not need to be electrified after the first movable plate 24 and the support plate 21 are fixed, so that the electric energy can be saved. Of course, the first electromagnet 221 may be another type of electromagnet such as a power-off type electromagnet, which is not limited in the embodiment of the present application.

Optionally, as shown in fig. 4, a portion of the pin 2231 in the bracket has a limiting section 22311, a cross section of the limiting section 22311 is larger than a size of the through hole 2221, and the cross section is a plane perpendicular to a length direction of the pin 2231. The length of the position-limiting section 22311 may be greater than the length of a first portion of the first magnet 221, which may refer to a portion of the first magnet 221 on a side away from the support plate 21 where the pin 2231 and the first electromagnet 221 are connected. The limiting section 22311 can prevent the first electromagnet 221 from being deformed due to an excessive pressure between the first electromagnet 221 and the first bracket 222 when the first spring 2232 pulls the first magnet 221 in a direction away from the support plate 21.

In an alternative embodiment, as shown in fig. 5, fig. 5 is a schematic structural diagram of an articulating mechanism of another desktop ultrasound apparatus provided in the embodiments of the present application.

The first electromagnet 221 may be bracket-connected to the first bracket 222 by a second elastic member 224.

Alternatively, the second elastic member 224 may include a second spring 2241, one end of the second spring 2241 is connected to the first electromagnet 221, and the other end is connected to the first supporter 222, and the second spring 2241 is in an extended state when the first electromagnet 221 is extended from the first supporter 222. That is, in the process of the first electromagnet 221 being attracted to the first flap 24, the first magnet 221 drives the second spring 2241 to move toward the direction close to the first flap 24, so that the first electromagnet 221 abuts against the first flap 24, at this time, the second spring 2241 is in an extended state, and then the second spring 2241 can apply a pulling force to the first electromagnet 221 toward the supporting plate 21, and the second spring 2241 can be used for fixing the first magnet 221 when the first electromagnet 221 is not attracted to the first flap 24, so as to prevent the first electromagnet 221 from shaking in the first bracket 222.

Optionally, the first fixing assembly may not include a second spring, and when the first electromagnet and the first movable plate are not adsorbed, the first electromagnet may retract into the first bracket under the action of gravity.

Alternatively, as shown in fig. 2 and 3, the first connection assembly 23 may include a linear guide 231, and the linear guide 231 extends in a direction parallel to the plate surface of the support plate 21. The linear guide 231 may further have a limiting hole 2311 at both ends thereof and a limiter (not shown in the drawings) installed in the limiting hole 2311, which may be, for example, a bolt or other limiting means to limit the position of the first movable plate 24, so as to prevent the first movable plate 24 and the support plate 21 from being separated in a direction f1 parallel to the plate surface of the support plate 21 when the first movable plate 24 and the support plate 21 move relatively.

As shown in fig. 2, the linear guide 231 may also have a slotted seat 2312, and the slotted seat 2312 may largely prevent the linear guide 231 from being deformed during installation and use.
