Description

Technical Field

[0002] The existing ultrasound equipment mainly includes a body, a support arm and an ultrasound host with a touch screen; the ultrasound host is connected to a flat panel fixing base, which is rotatably connected to the support arm to achieve pitch angle adjustment of the flat panel fixing base and the ultrasound host on it.

[0003] In the prior art, tablet mounts are all rotatably connected to the support arm via a damped shaft. The damping force required to rotate the tablet mount upward and downward is the same. However, due to the relatively heavy weight of the ultrasound host with a touch screen, rotating the tablet mount upward requires overcoming not only the damping force of the shaft but also the gravity of the tablet mount and the ultrasound host mounted on it.

[0053] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0054] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0056] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] Existing ultrasound equipment includes a support arm, an ultrasound main unit, and an angle adjustment mechanism connected between the support arm and the ultrasound main unit; the angle adjustment mechanism includes a flat plate fixing base fixed to the ultrasound main unit and a rotating shaft fixed to the support arm, and the flat plate fixing base is rotatably connected to the support arm via a damped rotating shaft. For example, when the gravity of the flat plate fixing base and the ultrasound main unit on it is 1000N, and the damping force acting on the rotating shaft is 1200N, rotating the flat plate fixing base upward requires overcoming both the gravity and the damping force, and the required force is approximately 2200N. Rotating the flat plate fixing base downward only requires overcoming the damping force, and the required force is approximately 200N. Obviously, rotating the flat plate fixing base upward is more laborious, affecting the user experience.

[0058] To solve the above problems, the present invention provides an ultrasonic device, such as Figure 1As shown, the ultrasound device includes an ultrasound main unit 100, a body 200, and a support arm 300. The body 200 includes a base 210 supported on the ground and a column 220 fixed above the base. The support arm 300 is connected to the column 220, and the ultrasound main unit 100 is connected to the support arm 300. The ultrasound main unit 100 is provided with a display screen or a touch screen. The ultrasound main unit 100 can be raised and lowered relative to the column 220 by moving the support arm 300. An angle adjustment mechanism is also connected between the support arm 300 and the ultrasound main unit 100, allowing the ultrasound main unit 100 to pitch, tilt, and flip relative to the support arm 300.

[0059] like Figure 1 As shown in Figure 3, the angle adjustment mechanism includes a support 1, a rotating shaft 2, a flat plate fixing seat 3, an elastic member, a rotation limit seat 7, and a bracket 8. One end of the rotation limit seat 7 is connected to the support arm 300, and the support 1 and bracket 8 are both fixedly connected to the other end of the rotation limit seat 7 facing away from the support arm 300. The flat plate fixing seat 3 is connected to the support 1 with damped rotation via the rotating shaft 2, and the ultrasound host 100 with a display or touch screen is mounted on the side of the flat plate fixing seat 3 facing away from the rotation limit seat 7. The elastic member is disposed between the support 1 and the flat plate fixing seat 3 and is in an energy storage state. The elastic member provides the flat plate fixing seat 3 with an elastic force in the direction of overcoming its own gravity. It should be noted that "rotational connection with damping" means that the two can rotate relative to each other under the action of an external force, and can also remain relatively stationary through damping when the external force disappears. The damping is essentially the static friction between the two.

[0060] This ultrasonic device utilizes an additional elastic member in a stored energy state disposed between the support 1 and the plate holder 3. The elastic force provided by the elastic member can partially or completely offset the weight of the plate holder 3 and the ultrasound main unit 100 mounted thereon. This reduces effort when rotating the plate holder 3 upward, thereby enhancing the product's competitiveness. For example, if the weight of the plate holder 3 and the ultrasound main unit 100 mounted thereon is 1000N, the elastic member provides the plate holder 3 and the ultrasound main unit 100 with an elastic support force of approximately 800N-1000N. When rotating the plate holder 3 upward, only the damping force and the relatively small weight of the device need to be overcome, resulting in a more labor-saving operation.

[0061] In some embodiments, as Figure 4 and Figure 5 As shown, the elastic member is specifically a torsion spring 4 in a twisted state. Due to its advantages of strong elastic force, simple structure, low cost, and ease of assembly, using a torsion spring 4 as the elastic member can reduce manufacturing costs. In alternative embodiments, the elastic member can also be a compression spring, leaf spring, air spring, or other elastic component capable of storing and releasing elastic energy.

[0062] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 As shown, the flat panel fixing base 3 is fixedly connected to the rotating shaft 2, and one end of the torsion spring 4 is connected to the support 1 and the other end is connected to the rotating shaft 2. The torsion spring 4 can provide elastic force to the flat panel fixing base 3 through the rotating shaft 2; compared with the method of directly connecting the other end of the torsion spring 4 to the flat panel fixing base 3, this torsion spring installation structure can be designed to be shorter because the rotating shaft 2 is closer to the support 1 relative to the flat panel fixing base 3. Therefore, a smaller torsion spring 4 can be used, which is conducive to the miniaturization design of the angle adjustment mechanism. In some alternative embodiments, one end of the torsion spring 4 is connected to the support 1 and the other end is connected to the flat panel fixing base 3. In other alternative embodiments, the rotating shaft 2 is fixed to the support 1, and the flat panel fixing base 3 is rotatable around the axis of the rotating shaft 2. One end of the torsion spring 4 is connected to the support 1 or the rotating shaft 2, and the other end of the torsion spring 4 is connected to the flat panel fixing base 3.

[0063] In some embodiments, as Figure 4 and Figure 5 As shown, the support 1 includes a base plate and a pair of lugs 11 perpendicular to and opposite to the base plate. Each lug 11 has a through hole 111, and the two through holes 111 are coaxially arranged. There are two rotating shafts 2, each of which is inserted into the through hole 111 of the corresponding lug 11. Each rotating shaft 2 is fitted with a gasket assembly. The cross-section of the portion of the rotating shaft 2 fitted with the gasket assembly is non-cylindrical. The opposite side surfaces of this section of the rotating shaft 2 are flattened from arc surfaces. The inner hole of the gasket assembly is a waist-shaped hole with the same cross-sectional dimensions as the section of the rotating shaft 2. When the rotating shaft 2 rotates, the gasket assembly rotates synchronously with the rotating shaft 2. A locking member 6 is threadedly connected to one end of the rotating shaft 2. The locking member 6 is used to press the gasket assembly against the lug 11 to generate a damping force between the lug 11 and the gasket assembly. The locking member 6 is specifically a locking nut. Arranging the shaft 2 in two sets not only facilitates assembly but also improves the stability of the flat panel mount 3 during rotation. The spacer assembly provides sufficient damping force on the shaft 2, enabling the flat panel mount 3 and its attached ultrasound device to hover at any angle within the angle adjustment range. Alternatively, a single shaft 2 can pass through both lugs 11, with locking mechanisms pressing the spacer assembly against the lugs 11 from both ends of the shaft 2.

[0064] In some embodiments, as Figure 4 and Figure 5As shown, the gasket assembly includes a first damping gasket 51 and a second damping gasket 53 located on opposite sides of the ear plate 11. The first damping gasket 51 is located between the ear plate 11 and the locking member 6. Both the first damping gasket 51 and the second damping gasket 53 are made of manganese steel and are composed of multiple stacked gaskets. The first damping gasket 51 and the second damping gasket 53 generate frictional damping with the ear plate 11 on opposite sides of the ear plate 11, which helps to increase the damping force and facilitate the installation of a relatively heavy ultrasonic mainframe on the flat plate fixing base 3.

[0065] Further, such as Figure 4 and Figure 5 As shown, the first damping washer 51 and the second damping washer 53 have multiple grooves on their sides facing the lug plate 11. These grooves are arranged circumferentially around the first damping washer 51 or the second damping washer 53 and are used to contain damping fluid. When the first damping washer 51 or the second damping washer 53 and the lug plate 11 rotate relative to each other, the damping fluid lubricates the rotating surfaces, maintaining a damping oil-lubricated state between the first damping washer 51 and the second damping washer 53 and the lug plate 11, thereby achieving a better damping effect.

[0066] In some embodiments, as Figure 4 and Figure 5 As shown, the gasket assembly also includes a compression gasket 52 located between the first damping gasket 51 and the locking member 6. The compression gasket 52 is a non-planar gasket with specific elasticity. When the locking member 6 is tightened, the compression gasket 52 is compressed and deformed. The elastic force generated by the deformation of the compression gasket 52 can effectively press the first damping gasket 51 against the ear plate 11, thereby ensuring the reliability of the damping effect. A first socket 521 is provided at the outer edge of the compression gasket 52, and a second socket 113 is provided on the ear plate 11. The spiral portion of the torsion spring 4 is sleeved on the outer periphery of the first damping gasket 51, and the first plug-in end 41 of the torsion spring 4 is inserted into the first socket 521, and the second plug-in end 42 of the torsion spring 4 is inserted into the second socket 113. The provision of the first socket 521 on the compression gasket 52 facilitates the torsion spring 4 sleeved on the first damping gasket 51 to be connected to the first socket 521 at a close distance, which is conducive to achieving a miniaturized and compact design of the structure.

[0067] In some embodiments, as Figure 4 and Figure 5As shown, the ear plate 11 is provided with an angle limiting slot 112, and the second damping washer 53 is provided with an angle limiting block 531 that extends into the angle limiting slot 112. The provision of the angle limiting block 531 enables adjustment of the rotational angle range of the tablet holder 3. The angle limiting slot 112 has an angle of 45 degrees, and the angle limiting block 531 rotates within an angle adjustment range of 15 degrees downwardly tilted relative to the horizontal plane to 30 degrees upwardly tilted relative to the horizontal plane. This arrangement meets the requirements of use while not requiring an increase in the size of the angle adjustment mechanism due to an increase in the upward tilt angle. It is understood that the angle limiting block can also be provided on the first damping washer 51.

[0068] In some embodiments, as Figure 5 、 Figure 6 and Figure 7 As shown, a concave cavity is provided on the side of the flat plate fixing seat 3 facing the support 1, and a pair of bosses integrally formed with the inner wall of the flat plate fixing seat 3 are provided in the concave cavity, and a placement groove 31 for placing the rotating shaft 2 is provided on the boss, and a pair of rotating shafts 2 are fixedly connected to the corresponding placement grooves 31. The concave cavity is provided in the flat plate fixing seat 3 to facilitate the rotation of the flat plate fixing seat 3 relative to the rotating shaft 2 and the support 1, which is conducive to achieving an overall miniaturized design. The rotating shaft 2 is fixed in the placement groove 31 formed on the boss. Since the boss is a solid structure with high strength and load-bearing capacity, it can meet the bearing capacity requirements of the connection between the flat plate fixing seat 3 and the rotating shaft 2, and is also conducive to achieving a miniaturized and lightweight design of the angle adjustment mechanism, especially the flat plate fixing seat 3. Specifically, the part of the rotating shaft 2 corresponding to the placement groove 31 is a flat shaft, and the placement groove 31 has the same shape as the flat shaft. The bottom of the placement groove 31 is provided with a positioning column 32 protruding outward and a pair of threaded holes 33 on both sides of the positioning column 32. The flat shaft of the rotating shaft 2 is provided with a positioning hole 21 corresponding to the position of the positioning column 32 and a pair of connecting holes 22 on opposite sides of the pair of positioning holes 21. The flat plate fixing seat 3 and the rotating shaft 2 are fixedly connected by pan head screws passing through the threaded holes 33 and the connecting holes 22.

[0069] Further, such as Figure 6 and Figure 7 As shown, the side of the flat plate fixing base 3 facing away from the support 1 is provided with an inner groove 36. The other end of the threaded hole 33 opens at the bottom of the inner groove 36. The design of the inner groove 36 allows the pan head screw to be hidden within the flat plate fixing base 3, facilitating the installation of the flat ultrasonic main unit 100 on the flat surface of the side of the flat plate fixing base 3 facing away from the support 1. A pair of hooks 37 are provided at the upper end of the side of the flat plate fixing base 3 facing away from the support 1. A pair of fixing holes 38 are also provided at the upper end of the side of the flat plate fixing base 3 facing away from the support 1 for securing the ultrasonic main unit 100.

[0070] In some embodiments, as Figure 8As shown in Figure 13, the rotation limit seat 7 includes a main body 71 and upper limit arms 72 and lower limit arms 73 integrally formed on opposite sides of the main body 71. A concave cavity is provided on the side of the flat plate fixing base 3 facing the rotation limit seat 7, and at least one of the upper limit arms 72 and the lower limit arms 73 extends into the concave cavity. When the flat plate fixing base 3 and the ultrasound host 100 thereon perform pitching motion relative to the rotation limit seat 7, at least one of the upper limit arms 72 and the lower limit arms 73 extends into the concave cavity of the rotation limit seat 7. The upward or downward flipping of the rotation limit seat 7 is limited by the upper limit arms 72 and the lower limit arms 73, so the rotation limit seat 7 and the ultrasound host 100 thereon can only perform pitching and flipping motions within a limited angle range, preventing the rotation limit seat 7 and the ultrasound host 100 thereon from flipping too far.

[0071] In some embodiments, as Figure 8 As shown in Figure 13, the length of the lower limit arm 73 extending outward relative to the main body 71 is greater than the length of the upper limit arm 72 extending outward relative to the main body 71. The concave cavity includes an upper concave cavity 34 and a lower concave cavity 35 located on opposite sides of the placement slot 31. The upper limit arm 72 is positioned correspondingly to the upper concave cavity 34, and the lower limit arm 73 is positioned correspondingly to the lower concave cavity 35. When the ultrasound main unit 100 on the tablet holder 3 is in a vertical position, the horizontal distance between the upper limit arm 72 and the bottom wall of the upper concave cavity 34 is greater than the horizontal distance between the lower limit arm 73 and the bottom wall of the lower concave cavity 35. When the ultrasound main unit on the tablet holder 3 is tilted upward by a first angle from the vertical position, the upper limit arm 72 is restrained against the inner wall of the upper concave cavity 34. When the ultrasound main unit on the tablet holder 3 is tilted downward by a second angle from the vertical position, the lower limit arm 73 is restrained against the inner wall of the lower concave cavity 35. The first angle is greater than the second angle. With such an arrangement, the maximum angle at which the rotation limit seat 7 can be turned upward relative to the horizontal plane can be greater than the maximum angle at which the rotation limit seat 7 can be turned downward relative to the horizontal plane.

[0072] Furthermore, the first angle is less than or equal to 30 degrees, and the second angle is less than or equal to 15 degrees. This configuration can further limit the angle adjustment range of the tablet fixing base 3, preventing deformation between the angle limit block 532 and the ear plate 11 due to excessive force. Moreover, since the size of the rotation limit base 7 is larger than that of the support 1, the rotation limit base 7 can provide stronger support for the tablet fixing base 3, preventing the support 1 from being deformed due to excessive pressure when the tablet fixing base 3 rotates too much. Therefore, the angle adjustment of the tablet fixing base 3 can be achieved by using a smaller-sized support 1, shaft 2, gasket assembly, etc. Even if the maximum upward tilt angle of the tablet fixing base 3 is adjusted from the existing maximum 15 degrees to 30 degrees, there is no need to increase the size of the support 1, shaft 2, gasket assembly or add additional components to provide reliable support.

[0073] In some embodiments, as Figure 8 and Figure 9 As shown, a bracket mounting slot 74 is formed between the upper limit arm 72, the lower limit arm 73, and the main body 71. A probe bracket 8 is fixedly mounted on the bracket mounting slot 74; probe hangers are mounted on both sides of the probe bracket 8, and the probe hangers are used to place instruments such as ultrasound probes. A bracket mounting slot 75 for placing the bracket 1 is also provided at the notch of the bracket mounting slot 74 facing the support 1. The walls of the bracket mounting slot 75 are located on the upper limit arm 72 and the lower limit arm 73. This arrangement allows for compact installation of the bracket 8 and the support 1 on the rotation limit seat 7.

[0074] Further, such as Figure 7 and Figure 8 As shown, a pair of positioning grooves 76 are provided at the bottom of the support mounting groove 75, and a pair of positioning pieces 12 extending into the positioning grooves 76 are provided on the bottom plate of the support 1. Among them, the length of the positioning groove 76 on the lower limit arm 73 is greater than the length of the positioning groove 76 on the upper limit arm 72. Correspondingly, the length of the positioning piece 12 that cooperates with the positioning groove 76 on the lower limit arm 73 is also greater than the length of the positioning piece 12 that cooperates with the positioning groove 76 on the upper limit arm 72. Such a design can prevent the reverse installation phenomenon.
