Description

Technical Field

[0001] This invention relates to the field of support technology, specifically to an extension support for the control panel of a portable ultrasound imaging device. Background Technology

[0002] Portable ultrasound imaging equipment has been widely used in emergency, bedside examination, primary healthcare and field rescue scenarios due to its small size, mobility and ease of operation. To improve the human-computer interaction experience, such equipment is usually equipped with a rotatable and retractable control panel and display screen connection frame, allowing doctors to freely adjust the screen angle and distance according to the examination posture. However, in actual use, as the display screen extends outward, its center of gravity gradually shifts forward, resulting in a significant decrease in the stability of the whole machine, which is prone to forward tilting, shaking or even tipping over, especially when operated with one hand or on an uneven table.

[0003] Most portable ultrasound devices on the market currently use fixed damping structures for their connecting brackets, such as spring compression, friction pad locking, or knob pre-tightening. These designs have significant drawbacks: if the initial damping is too small, it cannot effectively support the extended display screen, causing it to sag or rotate unexpectedly; if the initial damping is too large, it is difficult to operate and feels stiff when retracting or making small adjustments, affecting the smoothness of use. More importantly, the damping force cannot be dynamically adjusted according to the extended state, making it difficult to balance flexibility and stability. Therefore, we propose an extension bracket for the control panel of portable ultrasound imaging equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a control panel extension bracket for portable ultrasound imaging equipment, in order to solve the problems mentioned in the background art, where the control panel connection brackets of existing portable ultrasound equipment mostly use fixed damping, which cannot be dynamically adjusted with the extension distance of the display screen. This results in stiff operation when the stroke is short and insufficient support when the stroke is long, making it easy to shake or tip over. It also lacks accurate perception of the screen position and makes it difficult to achieve intelligent matching of resistance and stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a control panel extension bracket for a portable ultrasound imaging device, comprising a body, a chassis on the top of the body, and the chassis being rotatably connected to a turntable via a rotating rod, a connecting frame fixed on the side of the turntable, and a display screen being rotatably connected to the end of the connecting frame away from the turntable.

[0006] Also includes:

[0007] The triggering component is located between the chassis and the turntable. The triggering component includes a pressing block and a monitoring ring. When the connecting frame rotates and the display screen extends outward, the pressing block moves with the connecting frame and presses the switch on the surface of the monitoring ring. By detecting the triggering state of the switch, the current extension position of the display screen is determined.

[0008] The resistance adjustment component is located inside the chassis. It includes a friction plate and a cam. The friction plate is located at the bottom of the turntable, and the cam is located on both sides of the bottom of the friction plate. The rotation angle of the cam is synchronously controlled according to the trigger state of the switch on the monitoring ring. When the cam rotates, its highest point presses against the friction plate, thereby increasing the frictional damping force between the chassis and the turntable, and realizing adaptive adjustment of the rotation resistance according to the extension state of the display screen.

[0009] The stabilizing adjustment component is located inside the machine body. It includes a metal ring, an electromagnet, and a motor. The metal ring is fixed to the outer wall of the turntable, and the electromagnet is located below the metal ring. Based on the trigger state of the switch on the monitoring ring, the motor is synchronously controlled to drive the electromagnet to move vertically. When the electromagnet moves upward and approaches the metal ring, the magnetic attraction between the two increases, thereby enhancing the downward attraction force on the turntable. This allows for dynamic adjustment of the counterweight stability based on the extension distance of the display screen, preventing the equipment from tipping over or shaking due to a shift in the center of gravity.

[0010] The surface of the monitoring ring is sequentially equipped with trigger switch one, trigger switch two and trigger switch three, which correspond to the three position states of the display screen: retracted, half-extended and fully extended, respectively, to realize multi-level damping and counterweight adjustment.

[0011] The bottom sides of the pressure block are designed to be arc-shaped, so that it can smoothly trigger the switches at different positions during rotation, avoiding jamming or accidental triggering.

[0012] The chassis has an internal mounting cavity, and the friction pad is located at the top of the mounting cavity. The top of the friction pad is pressed tightly against the bottom of the turntable to ensure effective transmission of damping force.

[0013] The mounting cavity has two support rods fixed on both sides of the inner wall, and the top of the support rods is rotatably connected to a rotating rod. A cam is fixed on the outer wall of the rotating rod. One part of the cam is set as a semi-circle and the other part is set as a semi-ellipse, so that it can provide a stepped or continuously changing lifting height when rotating, corresponding to different damping levels.

[0014] Among them, the outer wall of the rotating rod two is fitted with a fixing ring, and the two sides of the fixing ring are fixed with support plates. The support plates are fixed to the inner wall of the mounting cavity to support and limit the rotation axis of the rotating rod two.

[0015] Among them, a metal plate is fixed on the outer wall of the rotating rod 2, and electromagnets 1, 2 and 3 corresponding to the metal plate are distributed sequentially on the inner wall of the fixing ring. When a certain trigger switch is activated, the corresponding electromagnet is energized to attract the metal plate, driving the rotating rod 2 and the cam to rotate to a preset angle, thereby realizing the graded automatic adjustment of the damping force.

[0016] The metal ring is fixedly connected to the outer wall of the turntable and is positioned above the electromagnet. The two are arranged coaxially to ensure that the magnetic force acts vertically downward, thus improving the stability of the counterweight.

[0017] Among them, the fourth electromagnet is located inside the machine body on the side away from the display screen. The surface of the machine body has a limiting groove that cooperates with the fourth electromagnet to guide its vertical lifting and lowering and prevent it from deviating.

[0018] Among them, the bottom of the electromagnet four is fixed with a connecting rod, and the bottom of the connecting rod is fixed with a moving ring. The internal thread of the moving ring is connected to a screw, the bottom of the screw is fixedly connected to the output shaft of the motor, and the side of the motor is fixed to the surface of the machine body. The screw is driven to rotate by the forward and reverse rotation of the motor, which drives the electromagnet four to rise and fall, thereby dynamically adjusting the distance and attraction force between it and the metal ring.

[0019] The present invention has at least the following beneficial effects:

[0020] Through position sensing and mechanical-electromagnetic linkage design, dual adaptive adjustment of damping force and counterweight is achieved: the further the display extends, the greater the damping of the turntable rotation, while the electromagnetic adsorption force on the rear side is enhanced simultaneously, effectively balancing the cantilever torque. This avoids stiff operation during short strokes and prevents the screen from sagging or the equipment from tilting forward during long strokes, significantly improving the stability and safety of use.

[0021] The longer the support extends, the greater the torque generated by the front control panel. Even slight touches or operational reaction forces can easily cause swaying or even loss of control. After automatically increasing damping or support, the joint can effectively "lock" the current position, achieving precise hovering and preventing panel shaking from affecting image observation or parameter adjustment. It remains light and flexible at short distances, facilitating quick adjustments, and provides stronger support feedback at long distances. Operators do not need to exert extra force to stabilize the panel, achieving an intelligent interactive experience of "light when it should be light, and stable when it should be stable," reducing operational fatigue, especially during long bedside examinations.

[0022] The entire adjustment mechanism is highly integrated inside the machine body, eliminating the need for external counterweights or complex transmission structures. It achieves intelligent support without increasing size or weight, fully preserving the mobility advantages of portable ultrasound equipment. It adopts mature mechanical structures such as arc-shaped pressure, screw lifting, and limit guidance, combined with graded electromagnetic control, making the system reliable, highly resistant to interference, suitable for complex hospital environments, and with low maintenance costs.

[0023] This support bracket allows for smooth one-handed adjustment and instant positioning, providing a smooth and stable operation. It reduces the burden of repeated fine-tuning for doctors, improves examination efficiency and human-machine interaction, and effectively ensures equipment stability and image observation continuity, especially in bedside, emergency, or mobile medical settings. It has outstanding clinical practical value. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figures 1 to 6The present invention provides a technical solution: a control panel extension bracket for a portable ultrasound imaging device, including a body 11, a base 12 on the top of the body 11, and the base 12 is rotatably connected to a turntable 13 via a rotating rod 14. A connecting frame 15 is fixed on the side of the turntable 13, and a display screen 16 is rotatably connected to the end of the connecting frame 15 away from the turntable 13, which facilitates multi-angle adjustment of the display screen 16 in a limited space, meets the visual needs of doctors in different examination postures, and improves the ease of operation and human-machine adaptability.

[0035] Also includes:

[0036] Trigger component 2 is located between chassis 12 and turntable 13. Trigger component 2 includes a pressing block 21 and a monitoring ring 22. When the connecting frame 15 rotates to extend the display screen 16 outward, the pressing block 21 moves with the connecting frame 15 and presses the switch on the surface of the monitoring ring 22. By detecting the trigger state of the switch, the current extended position of the display screen 16 is determined. This mechanical position sensing structure does not require electronic encoders or complex sensors, has low cost and high reliability, and can work stably in high humidity and dusty medical environments. It provides real-time and accurate feedback on the unfolded state of the display screen 16, providing a reliable input signal for subsequent damping and counterweight adjustment.

[0037] The resistance adjustment component 3 is located inside the chassis 12. The resistance adjustment component 3 includes a friction plate 31 and a cam 34. The friction plate 31 is located at the bottom of the turntable 13, and the cam 34 is located on both sides of the bottom of the friction plate 31. According to the trigger state of the switch on the monitoring ring 22, the rotation angle of the cam 34 is synchronously controlled. When the cam 34 rotates, its highest point presses against the friction plate 31, thereby increasing the frictional damping force between the chassis 12 and the turntable 13. This achieves adaptive adjustment of the rotation resistance according to the extension state of the display screen 16. This adaptive damping mechanism effectively solves the pain points of the traditional connecting frame 15, which is "shaky when loose and stuck when tight": the damping is moderate and the rotation is smooth when the stroke is short; the damping is enhanced when the stroke is long, preventing accidental rotation or sagging caused by the forward shift of the center of gravity, and significantly improving the stability and safety of operation.

[0038] The stabilizing adjustment component 5 is located inside the body 11. The stabilizing adjustment component 5 includes a metal ring 51, an electromagnet 52, and a motor 56. The metal ring 51 is fixed to the outer wall of the turntable 13, and the electromagnet 52 is located below the metal ring 51. According to the trigger state of the switch on the monitoring ring 22, the motor 56 is synchronously controlled to drive the electromagnet 52 to move vertically. When the electromagnet 52 moves upward and approaches the metal ring 51, the magnetic attraction between the two increases, thereby enhancing the downward attraction force on the turntable 13. This achieves dynamic adjustment of the counterweight stability according to the extension distance of the display screen 16, preventing the equipment from tipping over or shaking due to the shift of the center of gravity. This dynamic counterweight design uses electromagnetic attraction force to simulate variable physical counterweight, without the need to add extra weight or complex balance arms. While reducing the burden on the whole machine, it accurately counteracts the cantilever torque, effectively preventing the equipment from tilting forward, slipping, or tipping over. It is particularly suitable for mobile medical scenarios such as bedside and emergency rooms.

[0039] The surface of the monitoring ring 22 is sequentially equipped with trigger switches 1 23, 24, and 3 25, which correspond to the three position states of the display screen 16: retracted, half-extended, and fully extended, respectively. This enables multi-level damping and counterweight adjustment. The three-level position recognition and response mechanism achieves fine matching for different working conditions, avoids performance compromises caused by a single damping or counterweight mode, and balances flexibility, stability, and energy efficiency, thereby improving the consistency of user experience.

[0040] The bottom sides of the pressure block 21 are designed to be arc-shaped so that it can smoothly trigger the switch at different positions during rotation, avoiding jamming or accidental triggering.

[0041] The chassis 12 has an internal mounting cavity 6, and the friction plate 31 is located on the top of the mounting cavity 6. The top of the friction plate 31 is pressed tightly against the bottom of the turntable 13 to ensure effective transmission of damping force.

[0042] Support rods 32 are fixed on both sides of the inner wall of the mounting cavity 6, and the top of the support rods 32 is rotatably connected to the rotating rod 33. The cam 34 is fixed on the outer wall of the rotating rod 33. Part of the cam 34 is set as a semi-circle and the other part is set as a semi-ellipse, so that it can provide a stepped or continuously changing lifting height when rotating. Corresponding to different damping levels, the cam 34 adopts a composite profile design, which can achieve multi-level precise lifting within a limited rotation angle, which not only meets the needs of graded adjustment, but also avoids the operational jerking caused by sudden damping changes, and improves the smoothness of the feel.

[0043] A fixing ring 35 is fitted on the outer wall of the rotating rod 33, and support plates 4 are fixed on both sides of the fixing ring 35. The support plates 4 are fixed on the inner wall of the mounting cavity 6 to support and limit the rotation axis of the rotating rod 33.

[0044] A metal plate 36 is fixed to the outer wall of the rotating rod 33. Electromagnets 37, 38, and 39, corresponding to the metal plate 36, are distributed sequentially on the inner wall of the fixing ring 35. When a certain trigger switch is activated, the corresponding electromagnet is energized to attract the metal plate 36, driving the rotating rod 33 and cam 34 to rotate to a preset angle, realizing graded automatic adjustment of damping force. The electromagnetic drive method has a rapid response and precise control, and has no mechanical linkage parts, resulting in a simple structure and low failure rate. By selectively activating different electromagnets, the angle of cam 34 can be quickly positioned, ensuring that the damping adjustment is strictly synchronized with the position of display screen 16, thus improving the system's intelligence level.

[0045] During the use of portable ultrasound imaging equipment, the operator usually needs to rotate and pull out the display screen 16 towards themselves to obtain a better viewing angle and operating comfort. Specifically, when the connecting frame 15 rotates around the turntable 13 towards the operator, it causes the display screen 16 to extend outward in sync. The greater the rotation angle of the connecting frame 15, the farther the display screen 16 extends, and the farther its center of gravity is from the center of the machine body 11, resulting in a significant increase in the overturning torque borne by the turntable 13.

[0046] To cope with this change, as the turntable 13 rotates with the connecting frame 15, the pressing block 21 fixed on the connecting frame 15 moves synchronously and presses the three trigger switches set on the surface of the monitoring ring 22 in sequence: first trigger switch 1 23 is triggered, then trigger switch 24 is triggered, and finally trigger switch 3 25 is triggered, which correspond to the three states of "initial extension", "medium extension" and "maximum unfolding" on the display screen 16, respectively.

[0047] First-stage adjustment with slight extension: When the pressing block 21 triggers the trigger switch 23, the control system energizes the electromagnet 37, generating a magnetic force to attract the metal plate 36 fixed on the outer wall of the rotating rod 33. The metal plate 36 is attracted and drives the rotating rod 33 to rotate, which in turn drives the cam 34 on it to rotate synchronously. The semi-elliptical protrusion of the cam 34 begins to push the friction plate 31 upward, causing it to move slightly upward and fit against the bottom of the turntable 13, initially increasing the frictional damping between the chassis 12 and the turntable 13, preventing the turntable 13 from loosening or shaking under light load.

[0048] Second-level adjustment of moderate extension: When the display screen 16 continues to extend and triggers the trigger switch 24, the electromagnet 38 is energized, further attracting the metal plate 36, causing the rotating rod 33 and the cam 34 to continue rotating to a higher angle. At this time, the higher convex point of the cam 34 presses against the friction plate 31, pushing it to press more tightly against the bottom surface of the turntable 13, significantly increasing the rotation resistance and effectively balancing the unstable trend caused by the forward shift of the center of gravity.

[0049] The third-level adjustment is fully extended: When the display screen 16 reaches its farthest extended position, the pressure block 21 triggers the trigger switch 3 25, the electromagnet 3 39 is energized, and the cam 34 is driven to rotate to the maximum lifting angle. Its highest point forcefully lifts the friction plate 31, so that it presses the turntable 13 to the maximum extent, providing the strongest damping force, ensuring that even in the maximum cantilever state, the entire control panel remains stable and reliable, without the risk of sagging, shaking or accidental rotation.

[0050] Through the aforementioned three-level linkage mechanism, the device achieves the intelligent matching logic of "the more it extends, the greater the resistance." Based on the position-aware multi-level damping adaptive adjustment mechanism, it not only improves the stability and safety of the feel during operation, but also avoids the drawbacks of traditional fixed damping structures being too tight in short strokes and too loose in long strokes. It balances flexibility and reliability, significantly optimizing the doctor's user experience in ultrasound examinations.

[0051] Example 2

[0052] Please see Figure 7 The metal ring 51 is fixedly connected to the outer wall of the turntable 13 and is located above the electromagnet 52. The two are arranged coaxially to ensure that the magnetic force is applied vertically downward, which improves the stability of the counterweight. The coaxial vertical layout allows the magnetic attraction force to be accurately applied to the rear side of the turntable 13 along the direction of gravity, effectively converting it into an equivalent counterweight torque. This avoids the generation of lateral component forces that could cause the turntable 13 to wobble or get stuck, and significantly improves the anti-overturning ability and operational stability of the whole machine in the cantilever state.

[0053] Electromagnet 4 52 is located inside the body 11 on the side away from the display screen 16. The surface of the body 11 is provided with a limiting groove that cooperates with electromagnet 4 52 to guide its vertical lifting and lowering and prevent deviation. By placing electromagnet 4 52 on the opposite side of the center of gravity (away from the display screen 16), the lever arm effect is maximized, and efficient counterweight compensation is achieved with a smaller attraction force. The limiting groove structure ensures accurate guidance and no shaking during the lifting and lowering process, and prevents the magnetic circuit from being misaligned due to deviation, which would weaken the attraction force or generate friction noise.

[0054] A connecting rod 53 is fixed to the bottom of electromagnet 4 52, and a moving ring 54 is fixed to the bottom of the connecting rod 53. A screw 55 is threadedly connected to the inside of the moving ring 54. The bottom of the screw 55 is fixedly connected to the output shaft of the motor 56. The side of the motor 56 is fixed to the surface of the body 11. The motor 56 drives the screw 55 to rotate by reversing forward and reverse, thereby driving the electromagnet 4 52 to rise and fall, thereby dynamically adjusting the distance and adsorption force between it and the metal ring 51. The screw 55-moving ring 54 transmission mechanism has self-locking and high positioning accuracy, and can maintain the current position when the power is off to prevent the counterweight from failing unexpectedly. At the same time, the motor 56 precisely controls the lifting stroke to realize continuous or graded adjustment of the adsorption force, so that the counterweight strength is strictly matched with the extension distance of the display screen 16, taking into account both energy saving and dynamic stability.

[0055] During the use of portable ultrasound imaging equipment, when the operator rotates the display screen 16 towards themselves and gradually pulls it out, the center of gravity of the whole machine shifts forward. Especially in the fully extended state, the cantilever effect is significant, which can easily cause the equipment to tilt forward, sway, or even tip over. To solve this problem, this device simultaneously activates a counterweight adaptive adjustment mechanism based on position perception, which dynamically enhances the equivalent counterweight on the rear side of the turntable 13 through electromagnetic adsorption force, thereby achieving real-time balance of the center of gravity of the whole machine.

[0056] The specific work process is as follows:

[0057] First-stage counterweight adjustment for initial extension:

[0058] When the connecting frame 15 rotates and the pressure block 21 triggers the trigger switch 23 for the first time, the control system not only starts the damping adjustment, but also energizes the electromagnet 4 52. The energized electromagnet 4 52 generates magnetism, attracting the metal ring 51 fixed to the outer wall of the turntable 13, forming a downward magnetic attraction. Although this force is small, it can provide basic counterweight compensation in the slightly extended state and initially suppress the forward tilting tendency.

[0059] Second-stage counterweight adjustment for moderate extension:

[0060] When the display screen 16 continues to extend and triggers the second trigger switch 24, the control system starts the motor 56, which drives its output shaft to rotate the screw 55. Since the screw 55 is threadedly engaged with the moving ring 54, the rotational motion is converted into linear motion, pushing the moving ring 54 to move upward. The moving ring 54 drives the electromagnet 4 52 to move upward synchronously through the connecting rod 53, shortening the distance between it and the upper metal ring 51. According to the physical property that the magnetic force is inversely proportional to the square of the distance, the reduction of the distance significantly enhances the attraction between the two, thereby greatly increasing the downward attraction force on the rear side of the turntable 13, which is equivalent to increasing the counterweight mass on the side away from the display screen 16, effectively balancing the torque in the medium cantilever state.

[0061] Third-level counterweight adjustment for maximum deployment:

[0062] When the display screen 16 is fully extended and triggers the trigger switch 25, the control system continues to drive the motor 56 to rotate forward, causing the screw 55 to rotate further and push the electromagnet 52 to rise to the highest position, reaching the minimum safe distance between it and the metal ring 51. At this time, the magnetic attraction force reaches its maximum value, and the strong attraction force significantly increases the equivalent counterweight at the rear of the turntable 13, accurately offsetting the maximum forward tilting torque generated by the full extension of the display screen 16, ensuring that the equipment remains stable and reliable under extreme working conditions, without shaking or slipping.

[0063] Through the above three-level linkage control, the device realizes the intelligent balance strategy of "the further it extends, the stronger the rear counterweight". This design does not require the addition of physical counterweight blocks, but uses adjustable electromagnetic adsorption force to simulate dynamic counterweight. It saves space, reduces the weight of the whole machine, and avoids the disadvantages of the bulkiness and non-adjustability of traditional counterweight structures. It is especially suitable for bedside ultrasound, emergency or mobile diagnosis and treatment scenarios where the viewing angle is frequently adjusted, and significantly improves the operational safety, stability and user experience of the equipment.
