Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to an ultrasound trolley system, a quick-lock device for the ultrasound trolley system, and a mobile trolley. Background Technology

[0002] In ultrasonic trolley systems, the reliability of the connection between the ultrasonic equipment and the mobile trolley, as well as the space utilization rate, are crucial. In current related technologies, the locking tongue of the operating console slides along the front-back direction via a latch to engage or unlock with the insertion hole at the bottom of the ultrasonic unit. The unlocking drive needs to move synchronously along the front-back direction with the latch to complete the operation. While this design conforms to the operator's operating habits, the front-back movement of the latch and unlocking drive occupies a significant amount of space due to the sequential arrangement of the control components inside the ultrasonic unit. This severely restricts the arrangement of the control components, not only affecting the efficient use of the internal space of the ultrasonic unit but also potentially increasing the complexity of the equipment layout due to space constraints, which is detrimental to the miniaturization and integration design of the equipment. Utility Model Content

[0003] The purpose of this application is to provide an ultrasonic trolley system, a quick-locking device for the ultrasonic trolley system, and a mobile trolley, in order to solve the technical problem that the current locking mechanism cannot take into account the operator's operating habits and avoid occupying the front and rear space of the ultrasonic host.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, a quick-lock device for use in an ultrasonic trolley system is provided, comprising a locking tongue and an unlocking drive, wherein the locking tongue is movable between a locked position and an unlocked position along a first direction; the unlocking drive is movable along a second direction and is able to drive the locking tongue from the locked position to the unlocked position by moving; wherein the second direction is not collinear with the first direction.

[0006] As one embodiment of the first aspect, the quick-lock device further includes an unlocking rotating member, which is rotatable and slidably connected to the unlocking driving member. The unlocking driving member can drive the unlocking rotating member to rotate during movement, and the unlocking rotating member can move the locking tongue from the locked position to the unlocked position by rotating.

[0007] In one embodiment of the first aspect, the unlocking rotating component includes an unlocking shaft, a first lever, and a second lever. The unlocking shaft is rotatable, and the extension direction of the rotation axis of the unlocking shaft is perpendicular to the first direction and the second direction. The first lever is connected to the unlocking shaft and is located on the movement trajectory of the bolt. The second lever is connected to the unlocking shaft and slidably connected to the unlocking driving component. During the movement of the unlocking driving component toward the second direction, the unlocking shaft can be rotated by the sliding of the second lever relative to the unlocking driving component, so that the first lever moves the bolt from the locked position toward the unlocked position.

[0008] In one embodiment of the first aspect, the second lever is slidably connected to the unlocking drive member along the first direction.

[0009] In one embodiment of the first aspect, the unlocking drive has a sliding hole that extends along the first direction, and the second lever is slidably connected to the sliding hole.

[0010] As one embodiment of the first aspect, the first lever has an abutting arc surface that abuts against the latch.

[0011] As one embodiment of the first aspect, the quick-lock device further includes a first reset member, which is capable of applying a reset force to the bolt toward the locked position when the bolt moves toward the unlocked position; and / or, the quick-lock device further includes a second reset member, which is capable of applying a reset force opposite to the second direction to the unlocking drive member when the unlocking drive member moves toward the second direction.

[0012] In one embodiment of the first aspect, the latch moves between the locked position and the unlocked position by sliding or rotating.

[0013] Secondly, a mobile trolley for use in an ultrasonic trolley system is provided, including a mobile frame, an operating table, and a quick-locking device as described in any of the above embodiments. The operating table is connected to the mobile frame, and the locking tongue and the unlocking drive are both movably connected to the operating table.

[0014] Thirdly, an ultrasonic trolley system is provided, including an ultrasonic device and a mobile trolley as described in the above embodiments, wherein the ultrasonic device is capable of abutting against the operating table, and the locking tongue is engaged with the ultrasonic device when in the locked position.

[0015] The technical advantage of this application over the prior art is that when the unlocking drive moves along a second direction (such as the front-back direction or near the front-back direction), it can drive the locking tongue to move along a first direction (such as the left-right direction or near the left-right direction) toward the unlocking position, thereby unlocking the locking tongue from the ultrasonic host. This design retains the front-back movement of the unlocking drive in a way that conforms to operating habits, while changing the movement direction of the locking tongue to the left-right direction, avoiding the space occupied by the locking tongue in the front-back direction. This frees up more space in the front-back direction for the arrangement of internal control components of the ultrasonic host, reduces the complexity of the equipment layout, and is conducive to the miniaturization and integration design of ultrasonic equipment, while ensuring the ease of operation and structural stability of the quick-lock device.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0036] Please see Figure 1 and Figure 2This application provides an ultrasound cart system. The ultrasound cart system includes an ultrasound device (hereinafter referred to as ultrasound device 100) and a mobile cart (hereinafter referred to as mobile cart 200). The ultrasound device 100 can be stably mounted on the mobile cart 200. Medical staff can flexibly adjust the position of the ultrasound device 100 according to their own height, sitting or standing posture, and the patient's examination position to ensure comfortable operation and clear image viewing. Medical staff can also use the mobile cart 200 to carry portable mobile devices to different treatment areas, enabling bedside examinations and multi-department mobile diagnosis, thus improving the efficiency and flexibility of equipment use.

[0037] The ultrasound device 100 can be widely used in clinical diagnosis, emergency care, bedside examination, and other scenarios, such as screening for abdominal organ diseases, fetal monitoring in obstetrics and gynecology, cardiovascular function assessment, diagnosis of superficial organ lesions, and rapid assessment of acute and critical illnesses such as pneumothorax and internal bleeding at the emergency scene. It can also assist in procedures such as vascular puncture. During operation, the appropriate ultrasound probe should be selected and connected according to the area to be examined. After the ultrasound device 100 is turned on, the corresponding examination mode and parameters should be set, and coupling agent should be applied to the patient's examination area. Then, the ultrasound probe should be gently placed on the area to be examined and multi-angle scanning should be performed. During the examination, parameters such as gain and depth can be adjusted in real time to optimize the image. If abnormalities are found, the data can be frozen and saved in time. After the examination, the probe should be cleaned and disinfected, and the device should be turned off.

[0038] Please see Figure 3 and Figure 4 The ultrasonic device 100 includes an ultrasonic main unit 110 and a display device 130.

[0039] The ultrasound host 110 has abundant interfaces for connecting external components such as ultrasound probes, display devices 130, printers, and network devices to achieve data interaction and sharing. Specifically, the ultrasound host 110 includes a host housing 111 and control components. The host housing 111 has an internal cavity, in which the control components are housed. The control components include a probe card, a signal transmitting module, a signal receiving module, a digital signal processing unit (DSP), a central processing unit (CPU), a storage module, and a power management module. The ultrasound probe can be electrically connected to the control components through a connection with the probe card. When the ultrasound probe is connected to the ultrasound host 110, the signal transmitting module generates a high-frequency electrical signal, which drives the piezoelectric crystal in the ultrasound probe to vibrate, thereby emitting ultrasound waves. These ultrasound waves can penetrate human tissue and are reflected and scattered when they encounter tissue interfaces of different densities, generating echo signals carrying information about the human tissue. The signal receiving module can capture these weak echo signals, convert them into electrical signals, and then transmit them to the digital signal processing unit. In the DSP, the electrical signal undergoes a series of complex processes such as filtering, amplification, and gain compensation to enhance the useful signal and suppress noise interference, making the signal clearer and more accurate. The processed signal is then sent to the CPU, which performs image reconstruction calculations based on preset algorithms and programs, converting it into visualized ultrasound image data and controlling the display device 130 to display it for subsequent viewing, analysis, and diagnosis. The built-in power management module of the ultrasound host 110 effectively ensures the device's battery life during mobile use, and some high-end models also support fast charging technology, improving the ease of use of the device.

[0040] The display device 130 includes a display housing and a display screen. The display screen is mounted on the display housing and has a display surface 1301 for displaying images. The display device 130 is movably connected to the ultrasound host 110 to adjust the orientation of the display screen. Specifically, the display housing is movably connected to the host housing 111. The display screen can be a high-resolution liquid crystal display (LCD) or an organic light-emitting diode (OLED) display. For ease of operation, the display screen is usually equipped with touch functionality, allowing medical personnel to directly perform operations such as zooming, panning, measuring, and annotating images on the screen using finger touch, a stylus, etc., without the need for additional input devices, simplifying the operation process and improving work efficiency.

[0041] In practical use, the operation of the ultrasound device 100 is highly dependent on the spatial posture of the display device 130, causing the device to exhibit numerous problems in different usage scenarios. For example, when medical staff are seated during diagnosis, the display device 130 is difficult to switch flexibly between landscape and portrait modes, affecting the viewing and analysis of diagnostic images; when performing diagnostic work while standing, the flip angle, front-back position, or height of the display device 130 cannot meet the operational needs, resulting in inconvenience and reducing diagnostic efficiency and accuracy.

[0042] To resolve the above issues, please refer to [link / reference]. Figure 3 and Figure 4 In this embodiment, the ultrasound device 100 further includes an adjustment mechanism 120. The adjustment mechanism 120 is rotatably connected to the ultrasound host 110, and the display device 130 is rotatably connected to the adjustment mechanism 120. That is, the display device 130 is connected to the ultrasound host 110 through the adjustment mechanism 120. The adjustment mechanism 120 can support the display device 130 to increase the movable space of the display device 130, thereby meeting the viewing or operation needs of medical personnel from different angles or heights.

[0043] Optionally, the adjustment mechanism 120 includes a support arm 121 and a rotating arm 122. The support arm 121 is rotatably connected to the ultrasound host 110, the rotating arm 122 is rotatably connected to the support arm 121, and the display device 130 is rotatably connected to the rotating arm 122. The rotation axis of the display device 130 is not parallel to the rotation axis of the rotating arm 122. In this way, the display device 130 can rotate in at least two degrees of freedom, and its height and distance can be adjusted through the rotating arm 122 and the support arm 121, thereby expanding the adjustment range of the display device 130's posture and meeting the diverse needs of medical personnel.

[0044] The support arm 121 has a first extension end 1211 and a second extension end 1212, which are located at the two extension ends of the support arm 121, respectively. The first extension end 1211 is rotatably connected to the ultrasound host 110 about a first rotation axis L1, the rotating arm 122 is rotatably connected to the second extension end 1212 about a second rotation axis L2, and the display device 130 is rotatably connected to the rotating arm 122 about a third rotation axis L3. In other words, the support arm 121 can rotate relative to the ultrasound host 110 about the first rotation axis L1, the rotating arm 122 can rotate relative to the support arm 121 about the second rotation axis L2, and the display device 130 can rotate relative to the support arm 121 about the third rotation axis L3. Specifically, the first extension end 1211 is rotatably connected to the host housing 111, and the display device 130 is rotatably connected to the rotating arm 122 through the display housing.

[0045] In this configuration, the second rotation axis L2 is parallel to the first rotation axis L1. Thus, the adjustment mechanism 120 can be folded and unfolded by the rotation of the support arm 121 relative to the ultrasonic host 110 and the rotation of the rotating arm 122 relative to the support arm 121. In other embodiments, the second rotation axis L2 may also be set at an angle to the first rotation axis L1; this is not a limitation.

[0046] The third rotation axis L3 is set at an angle to the second rotation axis L2, so that the display device 130 has at least two degrees of rotational freedom.

[0047] The ultrasound device 100, through its unique multi-axis rotational connection design between the support arm 121, the rotating arm 122, and the display device 130, significantly reduces the dependence of the display device 130 on spatial posture. In practical use, when medical staff are seated for diagnosis, they can flexibly switch between landscape and portrait modes by rotating the display device 130 around the third rotation axis L3, facilitating image viewing and analysis. When standing for diagnosis, the rotation of the support arm 121 around the first rotation axis L1 and the rotation of the rotating arm 122 around the second rotation axis L2, in conjunction with the rotation of the display device 130, can precisely adjust its flip angle, forward / backward position, and height position to meet different operational needs, reduce operational inconvenience, effectively improve diagnostic efficiency and accuracy, and provide more flexible and efficient visualization support for clinical diagnosis and treatment.

[0048] For ease of understanding, the orientation of each structural component is described using the directions of up, down, front, back, left, and right as references. These orientations refer to the position of the ultrasound device 100 relative to the operator when it is being used as a laptop computer. The operator typically operates the ultrasound device 100 from the front. The display device 130 can be moved forward and backward via the adjustment mechanism 120. When the display device 130 moves forward, the end of the adjustment mechanism 120 away from the ultrasound host 110 can move towards the ultrasound host 110. At this time, the display surface 1301 of the display device 130 can be fastened to the ultrasound host 110 facing the operating surface 1101, reaching a folded position. Alternatively, the display surface 1301 of the display device 130 can also face away from the operating surface 1101, allowing the display device 130 to be used as a POC (Point of Care, bedside ultrasound device) (e.g., ...). Figure 5 As shown). When the display device 130 moves backward, the end of the adjustment mechanism 120 away from the ultrasound host 110 can move away from the ultrasound host 110, and the display device 130 is raised. At this time, the operator can adjust the angle of the display device 130 according to their own position (e.g., Figure 4 (As shown).

[0049] The main unit housing 111 has an operating surface 1101, peripheral side surfaces, and a bottom surface. The bottom surface faces away from the operating surface 1101, and the peripheral side surfaces surround and connect with the bottom surface and the operating surface 1101. The peripheral side surfaces include a front side, a left side, a rear side, and a right side, which are connected end to end. The front side faces away from the rear side, and the left side faces away from the right side. The left side is located to the left of the adjustment mechanism 120, and the right side is located to the right of the adjustment mechanism 120. The direction from the front side to the rear side is the front-back direction. The first extension end 1211 of the support arm 121 can be installed near the rear side of the main unit housing 111. The first rotation axis L1 and the second rotation axis L2 both extend in the left-right direction to accommodate the operator's operating habits.

[0050] Optionally, operable structures can be provided on the operating surface 1101. These operable structures include, but are not limited to, buttons, knobs, levers, trackballs, and touchpads. All operable structures on the ultrasound host 110 can be of the same type, or a combination of multiple types can be used; no restrictions are placed here. The operable structures are electrically connected to the control components. By deeply integrating physical interaction with electronic control, the intuitiveness and accuracy of operating the ultrasound device 100 are significantly improved. Medical personnel can directly issue commands through these operable structures, eliminating the need for complex menu navigation, shortening the operation path, and greatly improving response efficiency in emergency diagnosis or bedside examination scenarios.

[0051] Optionally, the third rotation axis L3 is perpendicular to the display surface 1301, so that the display device 130 can switch between horizontal and vertical screens by rotating relative to the rotating arm 122.

[0052] Optionally, the extension direction of the third rotation axis L3 can be perpendicular to the extension direction of the first rotation axis L1. This vertical arrangement allows the display device 130 to rotate freely in two independent dimensions: rotation around the first rotation axis L1 allows the display device 130 to adjust its pitch or horizontal displacement in space to accommodate the operating height requirements of medical personnel when standing or sitting; rotation around the third rotation axis L3 allows for quick switching between landscape and portrait modes, facilitating the viewing and analysis of different types of images. The two elements work together to cover the display angle requirements in almost all usage scenarios, greatly improving the ease of operation for medical personnel, reducing operational obstacles caused by poor display posture, and thus effectively improving diagnostic efficiency and accuracy, providing more efficient visualization support for clinical diagnosis and treatment.

[0053] Optionally, the connection point between the first extension end 1211 and the main housing 111 can be located at the edge of the operating surface 1101 to reduce the occupancy of the operating surface 1101. Specifically, the connection point of the first extension end 1211 can be close to or located on the rear side, and the operable structure can be close to the front side. Of course, in other embodiments, the first extension end 1211 can also be rotatably connected to a position near the center of the operating surface 1101; this is not a limitation.

[0054] Please see Figure 3 In some embodiments, the ultrasound host 110 has a first mounting groove 1102, and the first extension end 1211 is at least partially housed within the first mounting groove 1102 and rotatably connected to the ultrasound host 110 via a first rotating shaft. The first mounting groove 1102 provides precise positioning and storage space for the first extension end 1211, ensuring that the support arm 121 remains neatly connected to the ultrasound host 110, effectively reducing the overall size of the device and conforming to the lightweight and portable characteristics of portable devices. At the same time, the first rotating shaft enables the support arm 121 to rotate flexibly around the first rotation axis L1, enhancing the mechanical strength of the connection while ensuring the multi-angle adjustment function of the display device 130, preventing components from loosening or falling off due to frequent rotation, and ensuring that medical personnel can stably and smoothly adjust the posture of the display device 130 in different diagnostic and treatment scenarios, improving the user experience and operational reliability of the device. Specifically, the first mounting slot 1102 can be formed on the main unit housing 111, and the slot of the first mounting slot 1102 can be located on the operating surface 1101 and extend to the rear side of the main unit housing 111.

[0055] Optionally, the first mounting groove 1102 has first rotating grooves on its two sidewalls in the left-right direction. The first rotating shaft is fixedly connected to the first extension end 1211, and both ends of the first rotating shaft protrude from the first extension end 1211 in the left-right direction. The two ends of the first rotating shaft are rotatably inserted into the first rotating grooves to achieve a rotating connection with the ultrasound host 110. The two first rotating grooves provide precise positioning and support for the first rotating shaft, ensuring that the first extension end 1211 is evenly stressed when connected to the ultrasound host 110, and preventing the support arm 121 from wobbling or shifting during rotation.

[0056] In other embodiments, the first rotating shaft may also be fixedly connected to the two sidewalls of the first mounting groove 1102 in the left-right direction. The first rotating groove may be opened on the first extended end 1211, and the first rotating shaft may be rotatably inserted into the first rotating groove to achieve a rotatable connection with the first extended end 1211. No limitation is made here.

[0057] Please see Figure 3In some embodiments, the rotating arm 122 includes a turntable 1221 and a protrusion 1222. The turntable 1221 has a first disk surface and a second disk surface, both of which are planar, facing away from each other and parallel to each other. The protrusion 1222 protrudes from the first disk surface and is rotatably connected to the second extension end 1212 via a second rotating shaft. The display device 130 is rotatably connected to the turntable 1221 around a third rotating axis L3, which is perpendicular to the second disk surface. The protrusion 1222 cooperates with the second rotating shaft, allowing the rotating arm 122 to rotate smoothly around the second rotating axis L2, satisfying the tilt angle adjustment requirements of the display device 130. The turntable 1221 serves as the connecting carrier for the display device 130, and its flat disk surface provides a stable mounting base. Combined with the third rotating axis L3 perpendicular to the second disk surface, it enables operations such as switching between landscape and portrait modes and adjusting the tilt angle of the display device 130. In other embodiments, the first disk surface and the second disk surface may not be parallel, and at least one of the first disk surface and the second disk surface may not be a plane; no restrictions are imposed here.

[0058] Optionally, the display housing has a back surface 1302, which faces away from the display surface 1301. A first rotating structure is provided on the back surface 1302, and a second rotating structure is provided on the second disk surface of the display housing. The first and second rotating structures rotate in conjunction to allow the display housing to rotate around a third rotating axis L3. The back surface 1302 can abut against the second disk surface. This provides reliable circumferential support for the display device 130, effectively preventing wobbling or displacement during use and enhancing the stability of the connection structure. Furthermore, the friction between the two surfaces creates natural damping, allowing the display device 130 to maintain its current posture stably when no external force is applied, preventing accidental touches from altering the angle and affecting diagnostic operations. When external force is applied by medical personnel, it can be flexibly adjusted to the required angle, ensuring that medical personnel can conveniently and accurately adjust the display device 130 in various clinical scenarios to obtain the optimal viewing angle, thereby improving the efficiency and accuracy of ultrasound diagnosis.

[0059] The first rotating structure may be an annular protrusion or a circular protrusion protruding from the back surface 1302 of the display, and the second rotating structure may be an annular groove or a circular groove structure formed on the second disk surface; or, the first rotating structure may be an annular groove or a circular groove structure formed on the back surface 1302 of the display, and the second rotating structure may be an annular protrusion or a circular protrusion protruding from the second disk surface; or, the first rotating structure may be a circular groove structure formed on the back surface 1302 of the display, and the second rotating structure may be the annularly extended peripheral surface of the turntable 1221, with the turntable 1221 partially housed in the circular groove structure of the back surface 1302 of the display, which is not limited here.

[0060] It should be noted that there may be a damping force between the support arm 121 and the ultrasonic host 110, and there may also be a damping force between the rotating arm 122 and the support arm 121, so as to achieve the suspension of the display device 130. The mating position of the first rotating structure and the second rotating structure may also generate a damping force, which may exist simultaneously with the damping force between the second panel and the display back surface 1302, or only one of them may exist.

[0061] In other embodiments, the display back surface 1302 and the second panel may also be spaced apart, which is not limited here. The display housing may also be provided with multiple rotation positions, and the display housing can only maintain its current position when rotated to a rotation position. If it is between two adjacent positions, the display housing will automatically slide to the closer position.

[0062] Please see Figure 3 In some embodiments, the support arm 121 further includes a support portion 1213, which is connected between the first extension end 1211 and the second extension end 1212. The support portion 1213 extends along a straight path, and its extension direction is perpendicular to the extension direction of the first rotation axis L1. Thus, when the display device 130 adjusts its angle around the second rotation axis L2 and the third rotation axis L3, the support portion 1213 can serve as a stable force transmission medium, preventing the support arm 121 from wobbling or loosening due to uneven force distribution. Simultaneously, when the support arm 121 rotates relative to the ultrasound host 110, it provides the display device 130 with greater operational space. Medical personnel can achieve more precise and smooth multi-dimensional posture adjustments based on the vertically extending support portion 1213, significantly improving the operational comfort and diagnostic efficiency of the ultrasound equipment in different usage scenarios.

[0063] Please see Figure 3In some embodiments, the second extension end 1212 has a second mounting groove 1210, and the protrusion 1222 is at least partially located within the second mounting groove 1210 and rotatably connected to the sidewall of the second mounting groove 1210. Specifically, the protrusion 1222 is rotatably connected to the two sidewalls of the second mounting groove 1210 in the left-right direction via a second rotating shaft. Specifically, the second mounting groove 1210 has a second rotating groove on the two opposite sidewalls in the left-right direction, and the second rotating shaft is fixedly connected to the protrusion 1222 and rotatably passes through the second rotating groove to achieve a rotatable connection between the second rotating shaft and the second extension end 1212. The cooperation between the second rotating groove and the second rotating shaft ensures the smooth rotation of the rotating arm 122 around the second rotation axis L2, and enhances the stability of the connection structure through the constraint of the groove wall, effectively preventing loosening or displacement during rotation. The length of the protruding strip 1222 in the left-right direction can match the width of the second mounting groove 1210 in the left-right direction, that is, the two ends of the protruding strip 1222 in the left-right direction can be fitted with the two sidewalls of the second mounting groove 1210 in the left-right direction. In this way, the second mounting groove 1210 provides a precise installation and positioning space for the protruding strip 1222, avoiding lateral displacement during use.

[0064] In other embodiments, the second rotating shaft may also be fixedly connected to the two sidewalls of the second mounting groove 1210 in the left-right direction. The second rotating groove may be opened on the protrusion 1222, and the second rotating shaft may be rotatably inserted into the second rotating groove to achieve a rotatable connection with the protrusion 1222. No limitation is made here.

[0065] Please see Figure 3 In some embodiments, the support portion 1213 has a first support surface 121a and a second support surface 121b facing away from each other. Both the first support surface 121a and the second support surface 121b are parallel to the extension direction of the support portion 1213. The parallel extension of the first support surface 121a and the second support surface 121b enhances the overall rigidity of the support portion 1213 and reduces structural deformation during adjustment of the display device 130. The first extension end 1211 protrudes from the first support surface 121a and is rotatably connected to the ultrasonic host 110 via a first rotating shaft. Thus, the first extension end 1211 and the support portion 1213 form an L-shaped structure, such that the rotatable connection point between the first extension end 1211 and the ultrasonic host 110 is located on one side of the first support surface 121a of the support portion 1213. This provides sufficient space for the rotation of the support portion 1213 around the first rotation axis L1, avoiding structural interference with the ultrasonic host 110.

[0066] Please see Figure 3In some embodiments, the support arm 121 can rotate to a folded position. When the support arm 121 is in the folded position, the first support surface 121a faces and is parallel to the operating surface 1101. Optionally, when the support arm 121 is in the folded position, the first support surface 121a abuts against the operating surface 1101 to improve the stability of the support arm 121 in the folded position. The support portion 1213 has a clearance groove 121c on the first support surface 121a. The turntable 1221 can rotate to a storage position. When the turntable 1221 is in the storage position, the turntable 1221 is at least partially housed in the clearance groove 121c, and the second disc surface is parallel to the first support surface 121a or located on the same plane as the first support surface 121a.

[0067] When the support arm 121 is in the folded position and the turntable 1221 is in the stowed position, the display surface 1301 faces the operating surface 1101. Optionally, the display surface 1301 can rest against the operating surface 1101 at this time. When the support arm 121 is in the folded position and the turntable 1221 is in the stowed position, all components fit tightly and are neatly stowed, effectively reducing the overall size and space occupied by the equipment, making it easy to carry and store. The design of the clearance groove 121c for accommodating the turntable 1221 and the orientation of the display surface 1301 avoids mutual collision and wear between components, protects the display device 130 and the adjustment mechanism 120, and at the same time makes the folded state of the ultrasonic equipment 100 more regular, improving the safety and convenience of the equipment when moving or idle, and meeting the dual requirements of the ultrasonic equipment 100 for compactness and protection.

[0068] Optionally, the support portion 1213 has a first support plate 121d, a second support plate 121e, and a third support plate 121f connected in sequence. The second support plate 121e is bent relative to the first support plate 121d, and the third support plate 121f is bent relative to the second support plate 121e. The extending direction of the first support plate 121d is parallel to the extending direction of the third support plate 121f, and the extending direction of the second support plate 121e is perpendicular to the extending direction of the third support plate 121f. The second support plate 121e and the third support plate 121f together form a clearance groove 121c. Through the sequential bending connection of the first support plate 121d, the second support plate 121e, and the third support plate 121f, the overall rigidity of the support portion 1213 is enhanced to stably support the weight of the display device 130. Meanwhile, the second support plate 121e and the third support plate 121f naturally form an abutment groove 121c adapted to accommodate the turntable 1221, precisely matching the storage requirements of the turntable 1221. This provides a close-fitting accommodating space for the turntable 1221, ensuring a compact structure when folded, and also protects the turntable 1221 from damage caused by collisions during storage or movement, further enhancing the portability and durability of the device. The first support plate 121d, the second support plate 121e, and the third support plate 121f are integrally molded to improve the structural stability of the support section 1213.

[0069] Optionally, the depth of the clearance groove 121c is greater than or equal to the thickness of the turntable 1221 to avoid interference between the turntable 1221 and the ultrasonic host 110 when the adjustment mechanism 120 is in the folded position.

[0070] Please see Figure 3 In some embodiments, the ultrasound host 110 further includes a gripper 112 connected to the host housing 111. The gripper 112 is strip-shaped, with both ends connected to the front end of the host housing 111, and the middle portion of the gripper 112 spaced from the host housing 111, forming a gap for hand insertion. The operator can grasp the gripper 112 by inserting their fingers into this gap, thereby enabling the gripping and movement of the ultrasound device 100. The gripper 112 may be located on the front side of the host housing 111 to conform to the operator's gripping habits.

[0071] Please see Figure 1 and Figure 2 In some embodiments, the mobile trolley 200 includes a mobile frame 210, an operating table 220, and a quick-lock device 230.

[0072] The movable frame 210 can be placed on the ground and moved, and the operating table 220 can be installed on the movable frame 210. The operating table 220 can be movably connected to the movable frame 210, and the movable connection methods include, but are not limited to, detachable connection, rotating connection, and sliding connection. The operating table 220 can also be fixedly connected to the movable frame 210, and the fixed connection methods include, but are not limited to, snap-fit ​​connection, plug-in connection, screw connection, and one-piece molding connection. A quick-lock device 230 is installed on the operating table 220, which has a mounting surface 2210. The ultrasonic main unit 110 of the ultrasonic equipment 100 can be placed on the mounting surface 2210 and installed on the operating table 220 via the quick-lock device 230.

[0073] In an ultrasonic trolley system, the reliability of the connection between the ultrasonic device 100 and the mobile trolley 200, as well as the space utilization rate, are crucial. Current related technologies employ quick-lock devices, including a locking tongue and an unlocking drive, both of which are slidably connected to the operating table in the front-to-back direction. The ultrasonic unit has a locking hole on its bottom surface. The locking tongue slides in the front-to-back direction to engage or unlock with the locking hole, and the unlocking drive must move synchronously with the locking tongue in the front-to-back direction to complete the operation. While this design conforms to the operator's operating habits, the control components inside the ultrasonic unit are arranged sequentially in the front-to-back direction. The front-to-back movement of the locking tongue and unlocking drive occupies a significant amount of space in this direction, severely restricting the arrangement of the control components. This not only affects the efficient use of the internal space of the ultrasonic unit but may also increase the complexity of the equipment layout due to space constraints, hindering the miniaturization and integration design of the equipment.

[0074] To resolve the above issues, please refer to [link / reference]. Figure 6 In this embodiment, the quick-lock device 230 includes a locking tongue 231 and an unlocking drive 232.

[0075] The locking tongue 231 is movably connected to the operating table 220. The movable connection can be made in ways including but not limited to sliding connection, rotational connection, and elastic connection. The locking tongue 231 includes a latch 2311 and a locking protrusion 2312. The locking protrusion 2312 is connected to one end of the latch 2311 and is bent relative to the latch 2311 so that the locking tongue 231 is L-shaped. The latch 2311 is movably connected to the operating table 220.

[0076] The locking tongue 231 can move between the locked and unlocked positions along a first direction. The movement trajectory of the locking tongue 231 along the first direction can be a straight line, a curved line, or a broken line, as long as it has a component in the first direction. When the locking tongue 231 is in the locked position, it is engaged with the ultrasonic device 100. Optionally, the bottom surface of the main unit housing 111 has a locking hole 1112 communicating with the inner cavity. When the locking tongue 231 is in the locked position, it can hook onto the edge of the opening of the locking hole 1112. At this time, the latch 2311 passes through the locking hole 1112, and the latch protrusion 2312 is located in the inner cavity and abuts against the cavity wall. When the locking tongue 231 is in the unlocked position, it is released from engagement with the ultrasonic device 100, that is, the locking tongue 231 disengages from the edge of the locking hole 1112. In other embodiments, the locking tongue 231 may also be engaged with other parts of the main unit housing 111, such as the flange protruding from the main unit housing 111.

[0077] The unlocking drive component 232 is movably connected to the operating table 220. This movable connection can be achieved through various means, including but not limited to sliding, rotating, and elastic connections. The unlocking drive component 232 is capable of moving along a second direction. Specifically, it can move between a first position and a second position along this second direction. The second direction is not collinear with the first direction; that is, the first and second directions form an angle between them. The first direction can be left-right, and the second direction is perpendicular to the first direction, i.e., the second direction is front-back. In other embodiments, the second direction can be up-down, or it can form an acute angle with the first direction, i.e., the second direction has a front-back component and / or an up-down component. Alternatively, the second direction can be front-back, and the first and second directions form an acute angle, with the first direction having a left-right component.

[0078] The unlocking drive component 232 can move the locking tongue 231 from the locked position to the unlocked position. Thus, when the unlocking drive component 232 moves along a second direction (such as the front-back direction or near the front-back direction), it can drive the locking tongue 231 to move towards the unlocked position along a first direction (such as the left-right direction or near the left-right direction), thereby unlocking the locking tongue 231 from the ultrasonic host 110. This design retains the front-back movement of the unlocking drive component 232, which is consistent with operational habits, while changing the movement direction of the locking tongue 231 to the left-right direction. This avoids the locking tongue 231 occupying space in the front-back direction, thus freeing up more space in the front-back direction for the arrangement of internal control components of the ultrasonic host 110, reducing the complexity of the equipment layout, and facilitating the miniaturization and integration of ultrasonic equipment. At the same time, it ensures the ease of operation and structural stability of the quick-lock device 230.

[0079] In some embodiments, the quick-lock device 230 further includes an unlocking rotating member 233, which is rotatably connected to the operating table 220. The unlocking rotating member 233 is also slidably connected to the unlocking driving member 232. The unlocking driving member 232 can drive the unlocking rotating member 233 to rotate during movement. The unlocking rotating member 233 can move the locking tongue 231 from the locked position to the unlocked position by rotating. Through rotation, the unlocking rotating member 233 can flexibly connect the movement of the unlocking driving member 232 along the second direction with the movement of the locking tongue 231 along the first direction. Even if the first and second directions are at a large angle or even perpendicular, stable and smooth power transmission between them can be achieved, avoiding problems such as force transmission jamming or failure due to directional differences. This significantly improves the reliability of the quick-lock device 230 when switching between different directions of movement. Secondly, in terms of space optimization, compared to directly using linear transmission structures such as linkages to achieve direction conversion, the unlocking rotating component 233 transmits force through rotation, requiring a more compact space. This further reduces the additional space occupied in the front-to-back and left-to-right directions within the ultrasound host 110, providing more space for the refined arrangement of internal control components and better meeting the design requirements of miniaturization and integration of ultrasound equipment. Furthermore, from an operational experience perspective, the rotational characteristics of the unlocking rotating component 233 can, to some extent, buffer the force exerted by the unlocking drive component 232 during movement, making the unlocking operation smoother and more stable. This avoids a harsh operating feel or sudden impact caused by direct force transmission, improving user comfort and convenience. Finally, in terms of structural stability, the setting of the unlocking rotating component 233 can transform the direct rigid connection between the unlocking drive component 232 and the locking tongue 231 into an indirect rotating connection, reducing the structural wear caused by the difference in the direction of movement between the two, and at the same time, it can better adapt to the slight vibration or displacement that may occur during the use of the equipment, enhancing the overall durability and stability of the quick-lock device 230, and ensuring that it can reliably achieve the locking and unlocking functions for a long time.

[0080] Optionally, the unlocking rotating component 233 includes an unlocking shaft 2331, a first lever 2332, and a second lever 2333. The unlocking shaft 2331 is rotatably connected to the operating table 220, and the extension direction of the rotation axis of the unlocking shaft 2331 can be perpendicular to a first direction. The first lever 2332 and the second lever 2333 are both connected to the unlocking shaft 2331 and extend in different directions. The extension directions of the first lever 2332 and the second lever 2333 can be perpendicular to the extension direction of the rotation axis of the unlocking shaft 2331, or they can be set at an acute angle to the rotation axis of the unlocking shaft 2331. The first lever 2332 and / or the second lever 2333 can also extend along a curved path; there are no restrictions here.

[0081] The first lever 2332 is located on the movement trajectory of the latch 231, and the second lever 2333 is slidably connected to the unlocking drive member 232. During the movement of the unlocking drive member 232 from the first position to the second position, the sliding of the second lever 2333 relative to the unlocking drive member 232 drives the unlocking shaft 2331 to rotate, thereby causing the first lever 2332 to move the latch 231 from the locked position to the unlocked position. It can be understood that when the unlocking drive member 232 moves between the first and second positions, the second lever 2333 can slide relative to the unlocking drive member 232, and the unlocking drive member 232 can apply a rotational force to the second lever 2333, causing the unlocking shaft 2331 to rotate. The first lever 2332 can then move in a circular motion under the drive of the unlocking shaft 2331. If the locking tongue 231 is in the locked position, when the unlocking drive 232 moves from the first position to the second position, the rotation of the unlocking shaft 2331 can drive the first lever 2332 to move the locking tongue 231 towards the unlocking position. When the unlocking drive 232 moves to the second position, the locking tongue 231 is in the unlocking position, thus completing the unlocking of the locking tongue 231 and the ultrasonic main unit 110. After the main unit housing 111 is locked by the locking tongue 231, the ultrasonic main unit 110 is in the installation position, at which time the back of the ultrasonic main unit 110 abuts against the mounting surface 2210 of the operating table 220.

[0082] The quick-lock device 230 adds an unlocking rotating component 233, so that its unlocking rotating shaft 2331, first lever 2332 and second lever 2333 form a lever-type transmission structure. In this way, when the unlocking driving component 232 moves along the second direction (such as the front-back direction or near the front-back direction), the unlocking driving component 232 drives the unlocking rotating shaft 2331 to rotate through the sliding cooperation with the second lever 2333. This causes the first lever 2332 to move the locking tongue 231 along the first direction (such as the left-right direction or near the left-right direction) toward the unlocking position, thereby unlocking the locking tongue 231 from the ultrasonic host 110 locking hole 1112. This design retains the forward and backward movement of the unlocking drive 232, which conforms to operating habits, while changing the movement direction of the locking tongue 231 to the left and right direction. This avoids the locking tongue 231 occupying space in the forward and backward direction, thereby freeing up more space in the forward and backward direction for the arrangement of the internal control components of the ultrasonic host 110, reducing the complexity of the equipment layout, which is conducive to the miniaturization and integration design of ultrasonic equipment, while ensuring the ease of operation and structural stability of the quick-lock device 230.

[0083] It should be noted that when the locking tongue 231 is in the unlocked position, the movement of the locking tongue 231 toward the locked position can be achieved by the unlocking drive 232 moving toward the first position, or by the pushing of other structural components or forces, or by manual pushing, which is not limited here.

[0084] The first lever 2332 can abut against the latch 231 and is located on the side of the latch protrusion 2312 that is bent relative to the latch bar 2311. The first lever 2332 can also be sleeved on the latch 231, meaning that the first lever 2332 has at least two parts located on both sides of the latch 231 in the first direction. When the unlocking drive member 232 is in the first position, the first lever 2332 can abut against the latch 231 or be spaced apart from the latch 231; this is not limited here. In other embodiments, the rotation axis of the unlocking shaft 2331 can also be set at an acute angle to the first direction.

[0085] Optionally, the second lever 2333 is slidably connected to the unlocking drive member 232 along the first direction. Compared to other directions, the slidable connection of the second lever 2333 to the unlocking drive member 232 along the first direction can be consistent with the movement direction of the latch 231, reducing the force decomposition loss during transmission, reducing structural wear, and simplifying the matching design between the sliding hole 2320 and the second lever 2333, facilitating processing and assembly, and enhancing the overall stability and durability of the quick-lock device 230.

[0086] Optionally, the unlocking drive component 232 has a sliding hole 2320 extending along a strip-shaped path. The sliding hole 2320 can be a through hole or a blind hole. The depth direction of the sliding hole 2320 can be perpendicular to both the second and first directions. The second lever 2333 is slidably inserted through the sliding hole 2320, meaning the second lever 2333 can slide within the sliding hole 2320 along its extension direction.

[0087] Optionally, the second lever 2333 includes a connecting part and a sliding part. The connecting part is connected to the unlocking shaft 2331 and extends in a direction perpendicular to the rotation axis of the unlocking shaft 2331. The sliding part extends in a direction perpendicular to the extension direction of the connecting part and is slidably inserted into the sliding hole 2320.

[0088] Optionally, the second direction is perpendicular to the first direction, so that the movement trajectories of the unlocking drive 232 and the locking tongue 231 are orthogonally distributed. This avoids structural interference during their movement from a spatial layout perspective, ensuring smoother and more independent movement for each component. Simultaneously, this perpendicular relationship allows for efficient force conversion through the unlocking rotating component 233. When the unlocking drive 232 moves in a direction consistent with operating habits (such as the front-to-back direction), it can precisely drive the locking tongue 231 in a space-saving direction (such as the left-to-right direction). This maintains operational convenience while maximizing the use of internal space, reducing mutual interference between different components during movement, and improving the overall coordination and reliability of the quick-lock device 230.

[0089] Optionally, the extension path of the sliding hole 2320 is a straight path. Compared with an arc-shaped path, the linear extension of the sliding hole 2320 makes the sliding of the second lever 2333 smoother and the force transmission more direct, avoiding the transmission jamming or angle conversion deviation that may be caused by an arc-shaped path. This allows the moving distance of the unlocking drive 232 to form a stable correspondence with the displacement of the locking tongue 231, improving the accuracy of operation.

[0090] Optionally, the operating table 220 has a mounting cavity, and the operating table 220 also has a through hole 2211 on the mounting surface 2210 that communicates with the mounting cavity. The locking tongue 231 passes through the through hole 2211 and protrudes from the mounting surface 2210 so as to engage with the locking hole 1112 on the ultrasonic host 110.

[0091] Please see Figure 6 In some embodiments, the quick-lock device 230 further includes a first reset member 2341. The first reset member 2341 can apply a reset force to the latch 231 as it moves toward the unlocked position. The first reset member 2341 ensures that after the unlocking operation is completed, the latch 231 can automatically spring back to the locked position without manual reset, improving operational convenience. At the same time, when the latch 231 is in the locked position, the reset force can enhance the engagement tightness between the latch 231 and the ultrasonic host 110 locking hole 1112, reducing the risk of the latch 231 loosening due to equipment vibration or accidental contact, ensuring the stability of the connection between the ultrasonic host 110 and the operating table 220, and further improving the reliability and safety of the quick-lock device 230.

[0092] Optionally, the first reset member 2341 can be a spring, and the reset force can be the elastic force of the spring. The first reset member 2341 can abut against the latch 231. When the latch 231 is in the unlocked position, the first reset member 2341 can be in a compressed state. When the latch 231 is in the locked position, the first reset member 2341 can be in a compressed state or in a free state after the elastic force has been released. Alternatively, when the latch 231 is in the unlocked position, the first reset member 2341 can be in a stretched state. When the latch 231 is in the locked position, the first reset member 2341 can be in a stretched state or in a free state after the elastic force has been released.

[0093] Please see Figure 6In some embodiments, the locking tongue 231 is slidably connected to the operating table 220. Optionally, the quick-lock device 230 further includes a first slide bar 2342 connected to the operating table 220, the first slide bar 2342 extending along a first direction, and the locking tongue 231 slidably connected to the first slide bar 2342. The first slide bar 2342 can strictly constrain the locking tongue 231 to move only along a preset first direction (such as the left-right direction), preventing the locking tongue 231 from deviating, jamming, or shaking during movement, ensuring that it can accurately engage or unlock with the snap-fit ​​hole 1112 of the ultrasound host 110. The first slide bar 2342 can be located in the mounting cavity of the operating table 220 and connected to the cavity wall. The first reset member 2341 and the first lever 2332 are respectively located on both sides of the locking tongue 231.

[0094] Optionally, the quick-lock device 230 further includes two first mounting members 2343, both of which can be located in the mounting cavity and mounted on the cavity wall. The two first mounting members 2343 can be spaced apart. Two first slide rods 2342 are provided, with each end of the first slide rod 2342 connected to one of the first mounting members 2343. The two first slide rods 2342 are arranged in parallel, and the locking tongue 231 is slidably connected to the two first slide rods 2342. The two spaced first mounting members 2343 can firmly fix the ends of the first slide rods 2342, preventing deformation or displacement of the first slide rods 2342 when the locking tongue 231 slides, thus enhancing the rigidity of the overall structure. Two parallel first slide rods 2342 jointly support the locking tongue 231, preventing the locking tongue 231 from rotating, distributing the force on the locking tongue 231 during movement, reducing wear on individual first slide rods 2342, and simultaneously limiting the movement trajectory of the locking tongue 231 through dual guidance, ensuring its smooth sliding along the first direction, avoiding jamming or deviation, allowing the locking tongue 231 to accurately pass through the through hole 2211 and cooperate with the snap-fit ​​hole 1112 of the ultrasonic host 110. Furthermore, the mounting structure of the first mounting component 2343 cooperating with the first slide rod 2342 facilitates quick positioning of the first slide rod 2342 and the locking tongue 231 during production assembly, improving assembly efficiency and providing convenience for subsequent maintenance and component replacement, further ensuring the long-term stable operation of the quick-lock device 230. Two first reset components 2341 can be provided, each first reset component 2341 can be sleeved on a first slide rod 2342, with both ends of the first reset component 2341 abutting against the locking tongue 231 and the first mounting component 2343 respectively. In other embodiments, a first reset member 2341 may also be provided, and there is no limitation here.

[0095] In other embodiments, the locking tongue 231 can also be slidably connected to the operating table 220 through a slide rail, slide groove or other structure, which is not limited here.

[0096] Please see Figure 6In some embodiments, the quick-lock device 230 further includes a second reset member 2351. The second reset member 2351 applies a reset force to the unlocking drive member 232 as it moves toward the second position, moving it toward the first position. The second reset member 2351 ensures that after the unlocking operation is completed, the unlocking drive member 232 automatically returns to its initial first position without manual reset, simplifying the operation process and improving ease of use. Simultaneously, the reset force of the second reset member 2351 ensures that the unlocking drive member 232 remains stably in the first position when not in operation, preventing accidental movement of the unlocking drive member 232 due to unforeseen contact, thus preventing the latch 231 from unlocking unintentionally. This ensures the stability of the connection between the ultrasonic main unit 110 and the operating table 220, further enhancing the safety and reliability of the quick-lock device 230.

[0097] Optionally, the second reset member 2351 can be a spring, and the reset force can be the elastic force of the spring. The second reset member 2351 can abut against the unlocking drive member 232. When the unlocking drive member 232 is in the second position, the second reset member 2351 can be in a compressed state. When the unlocking drive member 232 is in the first position, the second reset member 2351 can be in a compressed state or in a free state after the elastic force has been released. Alternatively, when the unlocking drive member 232 is in the second position, the second reset member 2351 can be in a stretched state. When the unlocking drive member 232 is in the first position, the second reset member 2351 can be in a stretched state or in a free state after the elastic force has been released.

[0098] Please see Figure 6 In some embodiments, the unlocking drive component 232 is slidably connected to the operating table 220. Optionally, the quick-lock device 230 further includes a second slide bar 2352 connected to the operating table 220. The second slide bar 2352 extends along a second direction, and the unlocking drive component 232 is slidably connected to the second slide bar 2352. The slide bar extending along the second direction can strictly constrain the unlocking drive component 232 to move only along a preset trajectory, preventing it from deviating, shaking, or jamming during operation. This ensures that the unlocking drive component 232 cooperates more smoothly with the second lever 2333 through the slide groove, thereby stably driving the unlocking rotating component 233 to move. At the same time, the sliding cooperation between the second slide bar 2352 and the unlocking drive component 232 can disperse the force during operation, reduce component wear, extend the service life of the quick-lock device 230, and further improve the overall structural stability and motion reliability of the quick-lock device 230.

[0099] Optionally, the quick-lock device 230 further includes two second mounting members 2353, both located in the mounting cavity and mounted on the cavity wall. The two second mounting members 2353 are spaced apart. Two second slide rods 2352 are provided, with each end of the second slide rod 2352 connected to one of the second mounting members 2353. The two second slide rods 2352 are arranged in parallel, and the unlocking drive member 232 is slidably connected to the two second slide rods 2352. The secure fixing of the two second mounting members 2353 to the ends of the second slide rods 2352 prevents deformation or displacement of the second slide rods 2352 when the unlocking drive member 232 moves, thus enhancing the overall rigidity of the structure. Two parallel second slide rods 2352 jointly support the unlocking drive component 232, distributing the force during unlocking operations and reducing wear on individual slide rods 2352. Simultaneously, the dual guides strictly constrain the unlocking drive component 232 to slide smoothly along the second direction, preventing deviation, jamming, or shaking, ensuring smoother and more reliable cooperation between the unlocking drive component 232 and the second lever 2333. Furthermore, this modular mounting structure combining the second mounting component 2353 and the second slide rod 2352 facilitates rapid positioning and assembly during production, and also aids in subsequent maintenance and replacement, further enhancing the stability and durability of the quick-lock device 230. Two second reset components 2351 can be provided, each sleeved onto a second slide rod 2352, with both ends of the second reset component 2351 abutting against the unlocking drive component 232 and the second mounting component 2353, respectively. In other embodiments, only one second reset component 2351 may be provided; this is not a limitation.

[0100] In other embodiments, the unlocking drive 232 may also be rotatably connected to the operating table 220, so that the free end of the unlocking drive 232 away from its axis of rotation can move between the first position and the second position by making a circular motion, which is not limited here.

[0101] Please see Figure 6In some embodiments, the first lever 2332 has an abutting arc surface 2330 that abuts against the latch 231. The abutting arc surface 2330 extends along the extension direction of the first lever 2332, and the central axis corresponding to the abutting arc surface 2330 is located on the side of the abutting surface facing the latch 231. When the first lever 2332 moves the latch 231, the abutting arc surface 2330 provides a softer and more stable contact and force transmission to the latch 231. Compared to a flat or improperly positioned arc surface abutment, the design of the abutting arc surface 2330 reduces the impact force and wear at the moment of contact between the first lever 2332 and the latch 231, avoiding component damage caused by rigid collision. Meanwhile, the smooth transition of the abutting arc surface 2330 allows the direction of the actuating force to gradually change as the first lever 2332 rotates, ensuring that the locking tongue 231 is subjected to uniform force and moves smoothly during the actuation process, preventing jamming or deviation, improving the smoothness and reliability of the quick-lock device 230 operation, and extending the service life of the components.

[0102] The locking tongue 231 can also be connected to the operating panel 220 by rotation. In this case, the movement path of the locking tongue 231 is an arc-shaped path, but this does not affect the movement of the locking tongue 231 along the first direction. Please refer to [link / reference]. Figure 7 In some embodiments, the quick-lock device 230 further includes a locking rotating member 2361, which is connected to the operating table 220. Specifically, the locking rotating member 2361 is located in the mounting cavity and connected to the cavity wall. The locking tongue 231 is rotatably connected to the locking rotating member 2361, and the extension direction of the rotation axis of the locking tongue 231 is perpendicular to the first direction. The position of the first lever 2332 is offset from the position of the rotation axis of the locking tongue 231 in the first direction, so that the first lever 2332 can move the locking tongue 231 to rotate around the axis. Optionally, the first lever 2332 is located on the side of the locking rotating member 2361 near the through hole 2211, so as to move the latch 2311 to perform circumferential motion. In this case, the first reset member 2341 can be a torsion spring.

[0103] The locking tongue 231 can rotate within an angle range of up to 120° to move between the unlocked and locked positions. Compared to sliding along the first direction, the rotational movement of the locking tongue 231 saves space, making it particularly suitable for compact layouts within the mounting cavity of the operating table 220. Simultaneously, the rotational connection between the locking tongue 231 and the operating table 220 reduces frictional wear between the locking tongue 231 and surrounding components, resulting in smoother and more flexible switching actions. Combined with the stable connection between the engaging rotating component 2361 and the cavity wall, this ensures the locking tongue 231 maintains a stable posture during rotation, accurately engaging or unlocking with the ultrasonic host 110's locking hole 1112, thus improving the reliability and service life of the quick-lock device 230.

[0104] Optionally, the quick-lock device 230 further includes a third mounting member 2362, which is located within the mounting cavity and mounted on the cavity wall. A locking rotating member 2361 is connected to the third mounting member 2362 and extends normally along the first direction. The locking tongue 231 also includes a locking seat connected to the end of the latch 2311 away from the locking protrusion 2312, and the locking seat is rotatably connected to the locking rotating member 2361.

[0105] Please see Figure 6 In some embodiments, the unlocking drive 232 includes a connected unlocking plate 2322 and an unlocking protrusion 2321. The unlocking protrusion 2321 is slidably connected to the operating table 220, specifically slidably connected to the second slide rod 2352. The unlocking plate 2322 is located in the mounting cavity and behind the unlocking protrusion 2321, with a sliding hole 2320 formed on the unlocking plate 2322. The operating table 220 has a clearance hole 2212 extending into the mounting cavity on the mounting surface 2210. The unlocking protrusion 2321 passes through the clearance hole 2212 and protrudes from the mounting surface 2210. The second position of the unlocking drive 232 is located in front of the first position. The operator can press the unlocking protrusion 2321 forward by placing their finger behind it, thereby moving the unlocking drive 232 to the second position. This setting conforms to the direction of force applied by the operator's finger, improving the convenience of the unlocking operation. During the forward movement of the unlocking protrusion 2321, the unlocking plate 2322 can cover the rear side of the clearance hole 2212 exposed by the unlocking protrusion 2321 to improve the aesthetics of the operating table 220 and prevent external dust or impurities from entering the mounting cavity through the clearance hole 2212.

[0106] Please see Figure 8 and Figure 9 In some embodiments, the operating table 220 includes a tabletop 221 and a first protrusion 223. The tabletop 221 has a mounting surface 2210 for abutting against the bottom surface of the main unit housing 111 in the mounting position. The first protrusion 223 is connected to the edge of the tabletop 221 and protrudes from the mounting surface 2210. In this embodiment, the first protrusion 223 is located on the front side of the mounting surface 2210. The unlocking drive 232 protrudes from the mounting surface 2210 and is slidably connected to the first protrusion along a second direction. This design, where the unlocking drive 232 protrudes from the mounting surface 2210, facilitates quick contact of the unlocking drive 232 with the user's hand. Simultaneously, the user can use their fingers to press the unlocking drive 232 against the first protrusion, making the operation more effortless.

[0107] In some embodiments, the operating table 220 further includes a second protrusion 222, which is connected to the side of the first protrusion 223 away from the tabletop 221. The second protrusion 222 protrudes from the mounting surface 2210 and is located in front of the first protrusion 223. The height of the second protrusion 222 protruding from the mounting surface 2210 is greater than the height of the first protrusion 223 protruding from the mounting surface 2210. The first protrusion 223 has a first abutting surface 2231 and a pressing surface 2232. The first abutting surface 2231 faces the same direction as the mounting surface 2210, and the pressing surface 2232 faces the tabletop 221. The second protrusion 222 has a second abutting surface 2221, which faces the tabletop 221. Taking the mounting surface 2210 as a horizontal plane facing upwards as an example, the second abutting surface 2221 faces backwards, the first abutting surface 2231 faces upwards, and the pressing surface 2232 faces backwards. After the main unit housing 111 is placed in the installation position, the front side of the gripper 112 can abut against the first abutment surface 2231, and the lower side of the gripper 112 can abut against the second abutment surface 2221. In this way, the first abutment surface 2231 and the second abutment surface 2221 respectively limit and support the gripper 112 from the front and the lower sides, preventing the ultrasonic main unit 110 from shifting during use or movement, and enhancing the stability of the installation.

[0108] Please see Figure 8 and Figure 9In some embodiments, a pressing groove 2233 is formed on the pressing surface 2232, and the pressing groove 2233 communicates with the clearance hole 2212. The first protrusion 223 covers part of the clearance hole 2212 in a third direction, wherein the third direction is perpendicular to the first direction and the second direction. In this embodiment, the third direction can be the vertical direction. Specifically, the first protrusion 223 covers the front half of the clearance hole 2212 in the vertical direction. The unlocking protrusion 2321 is partially received in the pressing groove 2233. When the unlocking drive member 232 is in the first position, the unlocking protrusion 2321 protrudes rearward from the pressing surface 2232. When the ultrasonic host 110 is placed in the installation position, the rear side of the gripper 112 can be flush with the pressing surface 2232. In this way, the operator's fingers can reach the rear side of the unlocking protrusion 2321 when inserted into the gap between the middle of the gripper 112 and the host housing 111. The operator's fingers press the unlocking protrusion 2321 forward until the unlocking drive 232 moves to the second position to unlock the locking tongue 231. Then the fingers can pick up the gripper 112 so that the locking tongue 231 disengages from the snap-fit ​​hole 1112 on the host housing 111. The design of the pressing groove 2233 of the pressing surface 2232 and the unlocking protrusion 2321 allows the operator's finger to naturally touch and press the unlocking protrusion 2321 after inserting it into the gap between the gripper 112 and the main unit housing 111, thus unlocking the device. The flush arrangement of the rear side of the gripper 112 with the pressing surface 2232 ensures a smooth and seamless unlocking action and gripper 112 lifting operation, eliminating the need for additional hand adjustments and significantly improving operational convenience while maintaining reliable device connection and high efficiency. The unlocking protrusion 2321 can slide along the depth of the pressing groove 2233, reducing the gap between the unlocking protrusion 2321 and the sidewall of the pressing groove 2233, preventing external dust or impurities from entering the pressing groove 2233. In other embodiments, the pressing surface 2232 may not be flush with the rear side of the gripper 112; this is not a limitation.

[0109] Please see Figure 8In some embodiments, the operating table 220 further includes a positioning block 225, which is connected to the platform 221 and protrudes from the mounting surface 2210. The positioning block 225 is located at the end of the platform 221 away from the first protrusion 223, i.e., at the rear side of the platform 221. Correspondingly, the rear side of the main unit housing is also provided with a positioning hole 1103. When the ultrasonic main unit 110 needs to be placed on the operating table 220, the positioning block 225 can be inserted into the positioning hole 1103 on the main unit housing to limit the rear end position of the ultrasonic main unit 110. Then, the front end of the ultrasonic main unit 110 is moved downward until the gripper 112 is placed on the second abutment surface 2221. At this time, the first abutment surface 2231 restricts the ultrasonic main unit 110 from moving forward, and the positioning block 225 restricts the ultrasonic main unit 110 from moving backward, thereby achieving the limitation of the ultrasonic main unit 110 in the front-back direction.

[0110] Optionally, the platform 221 is provided with a guide slide 2261 on the mounting surface 2210. The guide slide 2261 extends in the front-to-back direction. Correspondingly, the bottom surface of the main unit housing is provided with a guide protrusion 113. After the guide protrusion 113 is placed on the mounting surface 2210, it can move from front to back under the limiting and guiding action of the guide slide 2261 until the positioning pin is inserted into the positioning hole 1103.

[0111] Optionally, a guide block 226 protrudes from the mounting surface 2210, and the left and right sides of the guide block 226 form the aforementioned guide slide 2261. The front half of the guide block 226 is a gradient section, and the width of the gradient section in the left and right direction gradually increases from front to back, so as to achieve rapid alignment between the guide block 226 and the guide slide 2261.

[0112] In other embodiments, the quick-lock device 230 can also be installed on other structural components. The quick-lock device 230 can also lock and unlock other devices besides the ultrasound device 100. Specific connections can be made according to usage requirements, and no limitations are imposed here. The ultrasound trolley system can also be other ultrasound diagnostic systems including the quick-lock device 230, and no limitations are imposed here.

[0113] Please see Figure 1 and Figure 2In some embodiments, the movable frame 210 includes a movable base 211 and a support 212. The movable base 211 is placed on the ground and is movable. The support 212 is connected to the movable base 211 and extends vertically. In this embodiment, the support 212 can extend vertically. The operating table 220 can be mounted on the top of the support 212 for easy operation. Optionally, the movable base 211 may include a movable base plate 2111 and multiple movable rollers 2112, which are connected to the movable base plate 2111 to achieve smooth movement of the movable base 211. The support 212 can extend and retract to raise and lower the operating table 220.

[0114] Other functional modules can also be connected to the mobile frame 210, for example, please refer to [link / reference]. Figure 1 In some embodiments, the mobile frame 210 further includes a probe extension mechanism 2131, a power supply mechanism 2132, a storage box 2133, and a cup sleeve 2134. The probe extension mechanism 2131 and the cup sleeve 2134 can both be connected to the bracket 212. The probe extension module is used to connect an ultrasound probe, increasing the types and number of ultrasound probes that the ultrasound trolley system can accommodate. The cup sleeve 2134 is also used to hold a cup, which can be a medical drug or instrument, or a daily-use water cup, to improve the convenience of the mobile frame 210. The storage box 2133 and the power supply mechanism 2132 can both be installed on the mobile base 211. The storage box 2133 can be installed above the mobile base plate 2111 for storing unused items. The power supply mechanism 2132 can be installed below the movable base plate 2111. The power supply mechanism 2132 can also be a battery. In this case, the power supply mechanism 2132 can be used to provide power to the ultrasound equipment 100 or the probe extension module. The power supply mechanism 2132 can also be a power connector to facilitate electrical connection with an external power source to achieve power transfer.

[0115] There are several ways to connect the control panel 220 and the movable frame 210. They can be directly or indirectly detached, or directly or indirectly rotatably connected. Examples are given below.

[0116] Please see Figure 10 In some embodiments, the movable frame 210 further includes two connecting bases 214, both of which are connected to the top of the support 212. The operating table 220 is detachably connected to the connecting bases 214. The orientation of the mounting surface 2210 of the operating table 220 is different when it is connected to one connecting base 214 than when it is connected to the other connecting base 214. In this way, the orientation of the operating table 220 can be adjusted by changing the connection of the operating table 220 to different connecting bases 214, thereby allowing the ultrasonic device 100 mounted on the operating table 220 to be adjusted to different postures.

[0117] When the control panel 220 is connected to the two connecting bases 214 respectively, the mobile trolley 200 can be in portable mode and POC mode respectively. In this way, the mobile trolley 200 can change the operating mode by connecting the control panel 220 to different connecting bases 214, which increases the usage scenarios of the mobile trolley 200.

[0118] Optionally, when the operating table 220 is connected to one of the connecting bases 214, the angle between the mounting surface 2210 and the horizontal plane can be greater than or equal to 0° and less than or equal to 15°, at which time the mobile trolley 200 is in portable mode; when the operating table 220 is connected to the other connecting base 214, the angle between the mounting surface 2210 and the horizontal plane can be greater than or equal to 85° and less than or equal to 95°, at which time the mobile trolley 200 is in POC mode.

[0119] Optionally, the operating table 220 has an operating bottom surface opposite to the mounting surface 2210. The operating bottom surface is provided with a connecting shaft 227, the extension direction of which can be parallel to the operating bottom surface. The connecting base 214 includes a connecting block 2141 and a limiting pin. The connecting block 2141 has a sliding groove 2140. The connecting shaft 227 is slidably connected to the sliding groove 2140 and can slide to a limiting position. The limiting pin is elastically connected to the connecting block 2141 and can elastically abut against the connecting shaft 227 located at the limiting position along the normal direction of the extension direction of the sliding groove 2140. That is, when the connecting shaft 227 slides along the sliding groove 2140 to the limiting position, the limiting pin can automatically and elastically abut against the connecting shaft 227, achieving rapid positioning and fixation of the operating table 220, preventing accidental sliding of the connecting shaft 227 during use, and ensuring operational stability. This elastic abutment limiting method allows for fixation without additional operation, and release is achieved simply by overcoming the elastic force of the limiting pin to push the operating table 220, allowing the connecting shaft 227 to slide out along the sliding groove 2140. This convenient operation balances flexibility and reliability. When the connecting shaft 227 slides to the limiting position, the operating bottom surface abuts against the connecting block 2141, thus supporting the operating table 220.

[0120] Optionally, the connecting block 2141 has a first connecting surface 2141a and a second connecting surface 2141b facing away from each other. Both connecting blocks 2141 are connected to the bracket 212 through the second connecting surface 2141b, and the first connecting surfaces 2141a have different orientations. The operating table 220 can be installed on the side with the first connecting surface 2141a. For example, one connecting base 214 has its second connecting surface 2141b facing the top of the bracket 212 and its first connecting surface 2141a facing upwards, while the other connecting base 214 has its second connecting surface 2141b facing the peripheral side of the bracket 212 and its first connecting surface 2141a facing horizontally. The two connecting bases 214 can be detachably connected to the bracket 212 or fixedly connected to the bracket 212. In the illustrated embodiment, the connecting blocks 2141 of the two connecting bases 214 are connected together and integrally formed for ease of processing. The ultrasonic device 100 can connect the main housing 111 to either of the two connecting bases 214.

[0121] In the illustrated embodiment, if the operating table 220 is connected to the connecting base 214 on the top of the bracket 212, after the ultrasound device 100 is installed on the operating table 220, the ultrasound device 100 can be used like a laptop. That is, the display device 130 can be raised by adjusting the rotation of the adjustment mechanism 120 relative to the ultrasound host 110. The operator can adjust the front-back position, up-down position, and tilt angle of the display device 130 as needed to adapt to the viewing and operation needs of the operator in a sitting or standing posture, just like using a laptop. If the operating table 220 is connected to the connecting base 214 on the side of the bracket 212, after the ultrasound device 100 is installed on the operating table 220, the ultrasound device 100 can be used like a POC device. That is, the support arm 121 is in the folded position, the display screen of the display device 130 faces away from the operating surface 1101 of the ultrasound host 110, and can switch between landscape and portrait modes by rotating itself around the normal of the display screen, meeting the usage requirements of compact space in the POC scenario. The mobile frame 210 allows the ultrasound device 100 to flexibly switch between "laptop" and "POC device" usage modes via the selective connection between the operating table 220 and the top or side of the support 212 to the base 214. This greatly improves the device's adaptability to different scenarios. The quick switching between the two modes does not require complicated disassembly and assembly, taking into account both the comfort of routine diagnosis and the portability of mobile diagnosis and treatment, effectively expanding the application range of the device.

[0122] The two connecting bases 214 are named first connecting base 214a and second connecting base 214b, respectively. First connecting base 214a is located at the top of bracket 212, and second connecting base 214b is located on the side of bracket 212. The second connecting surface 2141b of first connecting base 214a can be horizontal, and the second connecting surface 2141b of second connecting base 214b can be vertical.

[0123] Optionally, the sliding groove 2140 includes a first sliding segment 2140a and a second sliding segment 2140b. The first sliding segment 2140a is close to the opening of the sliding groove 2140 and extends in a direction perpendicular to the second connecting surface 2141b. For example, the first sliding segment 2140a of the sliding groove 2140 on the first connecting base 214a extends vertically, while the first sliding segment 2140a of the sliding groove 2140 on the second connecting base 214b extends horizontally. The second sliding segment 2140b is close to the bottom of the sliding groove 2140 and extends in a direction parallel to the first connecting surface 2141a. In this way, the extension path of the sliding groove 2140 is L-shaped. The connecting shaft 227 first enters the first sliding segment 2140a and then enters the second sliding segment 2140b. When the connecting shaft 227 abuts against the end wall of the second sliding segment 2140b away from the first sliding segment 2140a, the connecting shaft 227 reaches the limit position. In this way, when the connecting shaft 227 reaches the limit position, the sliding groove 2140 can limit the connecting shaft 227 in a direction perpendicular to the second connecting surface 2141b, so as to reduce the risk of separation between the operating table 220 and the connecting base 214.

[0124] Optionally, the first connecting surface 2141a of the first connecting base 214a is set at an angle to the horizontal plane. In the sliding groove 2140 of the first connecting base 214a, the second sliding segment 2140b extends obliquely downward from the first sliding segment 2140a. Thus, after the operating table 220 is placed on the first connecting surface 2141a and the connecting shaft 227 is placed on the first sliding segment 2140a, it can slide downward along the first connecting surface 2141a under its own gravity. At the same time, the connecting shaft 227 also slides towards the limit position along the second sliding segment 2140b under the same motion trend. This makes the process of installing the operating table 220 easier for the operator, improves the accuracy of the connecting shaft 227 reaching the limit position, and increases installation efficiency. Optionally, the angle between the first connecting surface 2141a of the first connecting base 214a and the horizontal plane is 5°-15°.

[0125] Please combine Figure 8 Optionally, the operating table 220 also includes a gripping member 224 connected to the table plate 221. The two ends of the gripping member 224 are rotatably connected to the table plate 221, and the operator can remove the operating table 220 from the connecting base 214 by gripping the gripping member 224. The gripping member 224 can be located on the side of the table plate 221 away from the second protrusion 222.

[0126] Optionally, each connecting block 2141 may have four sliding grooves 2140 arranged in a 2*2 array to improve the stability of the connection between the operating table 220 and the connecting base 214. Correspondingly, the operating table 220 also has four connecting shafts 227, each corresponding to one of the sliding grooves 2140.

[0127] In another embodiment, the operating table 220 can also be rotatably connected to the movable frame 210. In current ultrasound trolley systems, the operating table 220 and the movable frame 210 are mostly directly rotatably connected, which greatly limits the rotation range of the operating table 220. In actual diagnosis and treatment, medical staff need to both sit while diagnosing patients and stand while performing diagnostic work. The operating table 220 cannot flexibly move forward, backward, or up and down according to these different scenarios, making it difficult to adapt to the operational needs of medical staff, resulting in inconvenience and affecting diagnostic and treatment efficiency.

[0128] To resolve the above issues, please refer to [link / reference]. Figure 11 and Figure 12 The mobile trolley 200 also includes a deformation mechanism 215, through which the operating table 220 can be connected to the mobile frame 210. Specifically, the deformation mechanism 215 includes at least one polygonal frame 215a, which includes at least four support rods 2151. These support rods 2151 are sequentially and rotatably connected end to end to form a frame structure. The length and shape of these support rods 2151 can all be the same, or at least one can be different from the other support rods 2151. There is no limitation here, as long as both ends of each support rod 2151 are rotatably connected to the ends of the other two support rods 2151. The deformation mechanism 215 is rotatably connected to the mobile frame 210, specifically, it can be rotatably connected to the top of the bracket 212. The above-mentioned rotatable connection methods include, but are not limited to, shaft connection, universal ball connection, universal joint connection, and arc-shaped slide rail connection. The operating table 220 is connected to the polygonal frame 215a to move in position and change angle as the polygonal frame 215a deforms. The operating table 220 can be connected to the support rod 2151, or indirectly connected to the polygonal frame 215a via other structural components other than the polygonal frame 215a. The deformation mechanism 215 can be rotatably connected to the bracket 212 via the polygonal frame 215a, or indirectly rotatably connected to the bracket 212 via other structural components other than the polygonal frame 215a; no restrictions are placed here. The connection method between the operating table 220 and the deformation mechanism 215 can also be a fixed connection, such as snap-fit, adhesive, screw connection, or integral molding, or a movable connection, such as a rotating connection or a sliding connection; no restrictions are placed here.

[0129] The mobile trolley 200 connects the mobile frame 210 and the operating table 220 via a deformation mechanism 215. The polygonal frame 215a within the deformation mechanism 215 is a frame-like structure formed by at least four support rods 2151 rotatably connected end-to-end. The relative rotation of each support rod 2151 allows for flexible changes in the overall shape of the polygonal frame 215a, thereby enabling the operating table 220 to move forward and backward, up and down, and adjust its angle in multiple dimensions. This design precisely adapts to the operational needs of medical staff in different scenarios, such as sitting and standing during consultations, ensuring the operating table 220 is always in a convenient position for operation. This reduces operational inconvenience caused by unsuitable equipment placement and significantly improves diagnostic and treatment efficiency. Simultaneously, the frame-like structure of the polygonal frame 215a combines flexibility with support stability, ensuring smooth adjustment of the operating table 220 while stably supporting the weight of the ultrasound equipment, thus guaranteeing the reliability of the equipment during adjustment and use.

[0130] It should be noted that, in order to achieve the suspension of the operating table 220, the rotation between two adjacent support rods 2151 is limited by damping force. In this way, the polygonal frame 215a can only deform under the action of a larger external force, which improves the stability of the position of the operating table 220 in use.

[0131] Optionally, each support rod 2151 extends in a straight line to reduce interference between support rods 2151 or between support rods 2151 and other structural components.

[0132] Please see Figure 11 and Figure 12 In some embodiments, there are four support rods 2151, and the polygonal frame 215a is a quadrilateral structure. Compared with a polygon with more sides, the quadrilateral frame has a simpler structure, and the rotation and coordination of each support rod 2151 is easier to control. It can simplify the processing and assembly process and reduce costs while ensuring the adjustment flexibility of the operating table 220. Moreover, the quadrilateral has moderate stability and can meet the multi-directional adjustment requirements of the ultrasonic equipment under load. Specifically, the four support rods 2151 include a first support rod 2151a, a second support rod 2151b, a third support rod 2151c, and a fourth support rod 2151d. The two ends of each support rod 2151 are a first end and a second end, respectively. The first end of the first support rod 2151a is rotatably connected to the second end of the second support rod 2151b. The first end of the second support rod 2151b is rotatably connected to the second end of the third support rod 2151c. The first end of the third support rod 2151c is rotatably connected to the second end of the fourth support rod 2151d. The first end of the fourth support rod 2151d is rotatably connected to the second end of the first support rod 2151a.

[0133] In other embodiments, the support rod 2151 may also be equal to five, six or other values, which are not limited here.

[0134] Please see Figure 11 and Figure 12 In some embodiments, the deformation mechanism 215 further includes multiple rotating shafts 2152, the number of which is the same as the number of support rods. Adjacent support rods 2151 are rotatably connected via a rotating shaft 2152. The deformation mechanism 215 achieves rotatable connection between adjacent support rods 2151 through multiple rotating shafts 2152. Each rotating shaft 2152 independently corresponds to a set of adjacent support rods 2151, enabling more precise and smooth relative rotation of each support rod 2151, reducing jamming caused by loose connections. Simultaneously, the rotating shafts 2152 can distribute the force, enhancing the overall structural strength of the polygonal frame 215a and ensuring a stable and reliable deformation process. In other embodiments, adjacent support rods 2151 may also be rotatably connected via multiple rotating shafts 2152; this is not a limitation.

[0135] Taking a support rod 2151 with four members as an example, the deformation mechanism 215 has four rotating shafts 2152, which can be named as the first rotating shaft 2152a, the second rotating shaft 2152b, the third rotating shaft 2152c, and the fourth rotating shaft 2152d, respectively. The first support rod 2151a and the second support rod 2151b are rotatably connected through the first rotating shaft 2152a, the second support rod 2151b and the third support rod 2151c are rotatably connected through the second rotating shaft 2152b, the third support rod 2151c and the fourth support rod 2151d are rotatably connected through the third rotating shaft 2152c, and the fourth support rod 2151d and the first support rod 2151a are rotatably connected through the fourth support rod 2151d.

[0136] Please see Figure 11 and Figure 12 In some embodiments, the operating table 220 is fixedly connected to one of the support rods 2151. This ensures that the operating table 220 and the polygonal frame 215a move synchronously, avoiding the impact of relative displacement on operational stability. At the same time, the fixed connection enhances the load-bearing capacity of the operating table 220, preventing the ultrasonic equipment from shaking due to loose connections during adjustment or use, and improving the overall structural reliability.

[0137] Optionally, the first rotating shaft 2152a is rotatably connected to the bracket 212, and the operating table 220 is fixedly connected to the fourth support rod 2151d. The operating bottom surface of the operating table 220 abuts against the fourth support rod 2151d, which supports the operating table 220 to improve the connection stability between the operating table 220 and the quadrilateral frame. The first rotating shaft 2152a and the bracket 212 serve as a fixed fulcrum, and the operating table 220 is fixed to the fourth support rod 2151d, which is farther from the first rotating shaft 2152a. This utilizes the lever arm principle to significantly increase the operating space of the operating table 220. When each support rod 2151 rotates around its corresponding rotating shaft 2152, the end of the fourth support rod 2151d furthest from the first support rod 2151a can drive the operating table 220 to achieve a wider range of forward and backward, up and down, and angle adjustments. This fully meets the operational needs of medical personnel in different scenarios, such as sitting and standing during consultations, and avoids operational inconvenience caused by limited space.

[0138] Please see Figure 11 and Figure 12 In some embodiments, the deformation mechanism 215 further includes a rotating protrusion 2153 connected to the polygonal frame 215a. This rotating protrusion 2153 can be connected to the support rod 2151 or the rotating shaft 2152; no limitation is made here. The bracket 212 has a slotted hole 212a. The extension path of the slotted hole 212a can include a straight path, a curved path, or both; no limitation is made here. The rotating protrusion 2153 passes through the slotted hole 212a and can move along the extension direction of the slotted hole 212a. That is, the rotating protrusion 2153 is adapted to the slotted hole 212a in the width direction to prevent the rotating protrusion 2153 from moving in the width direction of the slotted hole 212a, thus improving the stability of the connection between the rotating protrusion 2153 and the bracket 212. The strip hole 212a provides a moving guide and limit for the rotating protrusion 2153, making the movement trajectory of the polygonal frame 215a more standardized during deformation, avoiding structural interference caused by offset. At the same time, the cooperation between the rotating protrusion 2153 and the strip hole 212a can help support the polygonal frame 215a and improve the stability of the deformation mechanism 215 during the adjustment process.

[0139] Please see Figure 11 and Figure 12In some embodiments, the rotating protrusion 2153 includes a rotating plate 2153a connected to the rotating shaft 2152 and a rotating rod 2153b connected to the rotating plate 2153a. Specifically, the rotating plate 2153a is connected to the first rotating shaft 2152a and extends radially along the first rotating shaft 2152a. The rotating rod 2153b can be connected to the first rotating shaft 2152a at both ends of the rotating plate 2153a, and the rotating rod 2153b slidably passes through the slot 212a. The rotating plate 2153a effectively extends the lever arm of the deformation mechanism 215. According to the lever principle, a longer lever arm allows the operator to adjust the position of the operating table 220 with less effort, reducing operational intensity, especially when moving heavier ultrasonic equipment, significantly improving operational convenience. Meanwhile, the rotating piece 2153a enables the deformation mechanism 215 and the support 212 to be rotatably connected through the rotating rod 2153b and the strip hole 212a. This eliminates the need to modify the existing polygonal frame 215a and other structures of the deformation mechanism 215, thus ensuring the integrity and stability of the original structure and smoothly achieving rotational cooperation with the support 212. This avoids problems such as reduced strength or complicated assembly that may be caused by structural modifications, and balances labor-saving operation with structural reliability.

[0140] Optionally, the top of the bracket 212 is provided with a groove 212b to form two spaced-apart supports 2121. Each support 2121 is provided with a strip hole 212a, and each strip hole 212a passes through two opposite plates of the support 2121. Both ends of the first rotating shaft 2152a are connected to a rotating protrusion 2153, and the rotating rods 2153b of the two rotating protrusions 2153 are respectively disposed in a strip hole 212a.

[0141] Optionally, the rotating rod 2153b can be magnetically connected to the bracket 212. After the operating table 220 is adjusted to a suitable position, the magnetic attraction can fix the position and angle of the first rotating shaft 2152a, preventing it from moving unexpectedly due to external forces or equipment vibration, and ensuring the stability of the operating table 220. The design of the rotating rod 2153b sliding through the strip hole 212a does not affect the flexible movement during adjustment, thus balancing stability and adjustability. The rotating rod 2153b can be magnetically connected to the wall of the strip hole 212a, and the cross-section of the rotating rod 2153b can also be I-shaped to magnetically connect to the plate surface of the support 2121.

[0142] Furthermore, the rotating rod 2153b includes an electromagnet. Compared to a permanent magnet, the electromagnet's magnetic attraction state can be controlled by switching it on and off. Operators can flexibly switch between fixed and adjustable modes as needed. When the position of the rotating rod 2153b needs adjustment, the electromagnet can be de-energized to release the magnetic attraction between the electromagnet and the bracket 212, thereby reducing the friction between the electromagnet and the wall of the slot 212a or the plate surface of the support 2121, allowing the rotating rod 2153b to move quickly within the slot 212a. After the position of the rotating rod 2153b is determined, the electromagnet can be energized to magnetically attract it to the bracket 212, increasing the friction between the electromagnet and the wall of the slot 212a or the plate surface of the support 2121, thus achieving a stable fixation of the rotating rod 2153b. This method is convenient to operate, provides controllable fixation, and enhances the flexibility of use.

[0143] In other embodiments, the rotating rod 2153b can also be a permanent magnet, in which case the rotating rod 2153b can be magnetically connected to the bracket 212 at all times. The operator can move or rotate the rotating rod 2153b by increasing the moving force or rotational force.

[0144] In some embodiments, the strip hole 212a extends along an arc-shaped path. The strip hole 212a may guide the rotating protrusion 2153 to move along an arc-shaped trajectory, so that the deformation of the polygonal frame 215a better matches the arc-shaped movement requirements of the operating table 220 for front-to-back and up-and-down adjustments, reducing movement resistance and making the angle and position adjustment of the operating table 220 more natural and smooth, adapting to the usage needs of medical personnel in different operating postures.

[0145] Optionally, the rotating protrusion 2153 can rotate within the slotted hole 212a to increase the rotatable space of the operating table 220. Specifically, the magnetic component is cylindrical and can rotate within the slotted hole 212a. In this way, when the polygonal frame 215a slides along the extension path of the slotted hole 212a, its own rotation reduces the frictional resistance with the inner wall of the slotted hole 212a, making the sliding process smoother and less strenuous, reducing component wear and extending service life. Simultaneously, the rotational characteristics can adapt to the angular changes brought about by the arc-shaped extension path of the slotted hole 212a, avoiding jamming or sticking due to rigid contact, ensuring the flexibility and continuity of the deformation mechanism 215 when adjusting the operating table 220, further improving operational convenience. It should be noted that when the magnetic component can rotate within the slotted hole 212a, the slotted hole 212a can also extend along a straight path.

[0146] Optionally, the magnetic component has an arc-shaped cross-section that matches the width of the strip hole 212a. This allows the magnetic component to slide only along the extension path of the strip hole 212a, preventing rotation. This effectively limits the rotation range of the polygonal frame 215a. This avoids structural interference or component damage to the operating table 220 due to excessive rotation, ensuring flexible adjustment within a safe range. It also makes the rotation trajectory of the operating table 220 more stable and controllable, improving operational safety and reliability. Furthermore, the arc-shaped cross-section reduces frictional resistance during sliding, making the adjustment process smoother.

[0147] Please see Figure 11 and Figure 12 In some embodiments, two polygonal frames 215a are provided, and adjacent support rods 2151 of each polygonal frame 215a are rotatably connected by a rotating shaft 2152. That is, both ends of the same rotating shaft 2152 can be connected to two polygonal frames 215a to achieve the connection of the two polygonal frames 215a. The operating table 220 is connected to the fourth support rod 2151d of the two polygonal frames 215a. The two polygonal frames 215a work together to provide balanced support to the operating table 220 from both sides, distributing the weight of the ultrasonic equipment, reducing the stress on a single polygonal frame 215a, and extending its service life. At the same time, the double-frame structure can improve the overall rigidity of the deformation mechanism 215, making the operating table 220 more stable during adjustment and reducing shaking.

[0148] In other embodiments, the polygonal frame 215a may be provided in three or more quantities. These multiple polygonal frames 215a may be arranged in parallel to further improve the structural strength. There is no limitation here, as long as the overall regular deformation of the deformation mechanism 215 can be achieved.
