Description

Technical Field

[0001] This utility model relates to the field of ultrasonic equipment, specifically to an ultrasonic equipment control panel and ultrasonic equipment. Background Technology

[0002] A trackball in ultrasound equipment is a human-computer interaction input device, typically located on the control panel. It allows the operator to control the movement of a cursor on the screen by directly rotating the ball, without having to slide it across the desktop. Trackballs are particularly important for ultrasound examinations and image analysis that require precise cursor control, especially during real-time ultrasound scans and image measurements. Current trackballs are generally secured to a base with a clamping ring to prevent them from falling out.

[0003] To ensure the sensitivity of cursor movement, the trackball needs to be cleaned or replaced when maintaining the ultrasound equipment. However, since most of the trackball is embedded in the socket, and the part exposed in the socket is also spherical, it is not easy to remove the trackball from the socket. Utility Model Content

[0054] An embodiment of the ultrasonic device in this utility model:

[0055] Ultrasound equipment is a medical diagnostic tool that uses the principle of ultrasound waves to create images. It is widely used in clinical medicine, such as for examinations of the abdomen, cardiovascular system, gynecology, obstetrics, and urinary system. Ultrasound equipment primarily works by emitting ultrasound waves and then receiving the echo signals reflected from human tissues. After processing, these echoes form images, helping doctors diagnose lesions. Ultrasound equipment can be categorized into portable ultrasound equipment, desktop ultrasound equipment, and mobile ultrasound equipment, among others. Portable ultrasound equipment is small, lightweight, and easy to carry, making it suitable for fieldwork or bedside examinations. Desktop ultrasound equipment offers more comprehensive functions and higher image resolution, generally suitable for use in fixed locations within hospitals. Mobile ultrasound equipment is equipped with wheels, allowing for easy relocation and greater flexibility to meet different usage scenarios.

[0056] The ultrasonic device in this invention can be any of a portable ultrasonic device, a desktop ultrasonic device, or a mobile ultrasonic device. For example, please refer to... Figure 9The ultrasonic device of this invention can be a mobile ultrasonic device, including a walking module 100, an ultrasonic main unit 200, an ultrasonic device control panel 300, a display module 400, and an ultrasonic probe (not shown in the figure). The ultrasonic main unit 200 also serves as a support structure for the ultrasonic device. The walking module 100 includes casters and a drive mechanism located at the bottom of the ultrasonic main unit 200, enabling the ultrasonic device to move. The ultrasonic device control panel 300 and the display module 400 are supported on a bracket located on top of the ultrasonic main unit 200 and can move with the ultrasonic main unit 200.

[0057] It is particularly important to note that, Figure 9 The ultrasonic device shown is only used to illustrate one possible structural layout of the ultrasonic device in this utility model, and does not limit this utility model to necessarily using the ultrasonic device described herein. Figure 9 The specific structure shown.

[0058] The ultrasound equipment control panel 300 is the main component for operator interaction with the equipment, and it typically integrates various control elements. Those skilled in the art will understand that when using ultrasound equipment, the operator can perform operations such as imaging mode selection, probe control, depth and gain adjustment, image saving and export, and measurement through the ultrasound equipment control panel 300. It should be noted that these operations are selectable; the operator can perform one or more of these operations through the ultrasound equipment control panel 300, or perform other operations not listed above.

[0059] Please refer to Figure 1 and Figure 2 In one embodiment, the ultrasound device control panel 300 may include a panel body 310, a trackball 330, and a pressure ring 340. Compared to a mouse or touch screen, the trackball 330 can be directly moved, providing more accurate positioning and enabling fine image adjustments and probe movement, helping doctors to observe lesions more accurately. In some cases, the operator can also directly perform image zooming, rotation, and other operations using the trackball 330, reducing hand fatigue.

[0060] Please refer to Figure 1 and Figure 2 In one embodiment, the panel body 310 includes a first housing 311 and a second housing 312 fixedly connected together. The first housing 311 and the second housing 312 can form a mounting cavity, in which a circuit board, a trackball sensor, a push-button switch, and other structures can be disposed. The second housing 312 can be a top housing, and a portion of the trackball 330 can protrude from the top housing for the operator to rotate.

[0061] The trackball 330 can be solid or hollow, and is typically made of silicone, plastic, phenolic resin, polyurethane (PU), polyoxymethylene (POM), nylon (PA), polypropylene (PP), or other engineering plastics. For professional or industrial applications, the trackball 330 can also be made of metal, such as stainless steel.

[0062] To position the trackball 330, the panel body 310 includes a ball mount 320 for the trackball 330 to be inserted. Please refer to... Figure 1 and Figure 2 In one embodiment, the ball seat 320 is fixedly assembled between the first housing 311 and the second housing 312. The top end of the ball seat 320 abuts against the top inner wall of the second housing 312, and the bottom end of the ball seat 320 abuts against the inner wall of the first housing 311.

[0063] The panel body 310 has a first side and a second side opposite to the first side. The first side may be, for example, a... Figure 1 The top side, the second side could be, for example, the top side. Figure 1 The ball seat 320 has a cavity 321 for the trackball 330 to be inserted into it. The first side of the panel body 310 has a pick-and-place opening 322, which communicates with the cavity 321, allowing the trackball 330 to enter or leave the ball seat 320. When the trackball 330 is inserted into the ball seat 320, it protrudes from the first side of the panel body 310 for user operation.

[0064] like Figure 1 and Figure 2 The receiving cavity 321 is actually a cavity that can roughly fit the shape of the trackball 330. The cavity can be roughly hemispherical so that the trackball 330 can be directly placed into the receiving cavity 321. It should be noted that in some other embodiments, the ball seat 320 can also be integrally formed with the first housing 311 or the second housing 312 of the ultrasonic equipment control panel 300.

[0065] The trackball sensor may protrude from the inner wall of the receiving cavity 321 to detect the rolling direction and rolling speed of the trackball 330. The trackball sensor can be an optical sensor or a mechanical sensor. An optical sensor, for example, can use infrared or visible light to detect minute displacements of the ball and calculate the movement direction and speed of the trackball 330 by measuring changes in reflected light. A mechanical sensor may include a ball and an encoder, measuring the movement of the trackball 330 through physical contact.

[0066] To prevent the trackball 330 from detaching from the receiving cavity 321, in some embodiments, the ultrasonic device control panel 300 further includes a retaining ring 340. The retaining ring 340 can be fixed to the access port 322 of the panel body 310. Specifically, the retaining ring 340 can be fixed to the retaining ring connection portion 323 of the ball seat 320 to prevent the trackball 330 from detaching from the ball seat 320 when the trackball 330 is embedded in the ball seat 320. In one embodiment, such as Figure 1 and Figure 2 In this context, the pressure ring connection portion 323 is the edge of the loading / unloading port 322 on the second housing 312. In some other embodiments, the pressure ring connection portion 323 can take other forms for ball seats 320 with other structures. Generally speaking, the pressure ring connection portion 323 is the local part on the panel body 310 that has an assembly relationship with the pressure ring 340. The specific location of the pressure ring connection portion 323 is not limited and can be located on any one or more parts of the panel body 310.

[0067] The panel body 310 includes a retaining ring seat 350. For example, the portion of the second housing 312 located around the pick-up / placement port 322 forms the retaining ring seat 350. The retaining ring 340 can be fixed at the pick-up / placement port 322, thereby connecting to the retaining ring seat 350. When the trackball 330 rolls in the ball seat 320, it needs to be able to be positioned relatively stably so that the deviation of the trackball 330 from the set center position when it is operated and rolled does not exceed a certain range (e.g., 0-0.5mm) to ensure the detection accuracy of the trackball sensor. Therefore, in some other embodiments, when the retaining ring seat 350 and the ball seat 320 are separate structures, a positioning structure is provided between the retaining ring seat 350 and the ball seat 320.

[0068] In one specific embodiment, please refer to Figure 1 and Figure 6 The positioning structure includes circumferential positioning structure, radial positioning structure and axial positioning structure.

[0069] Please refer to the following: Figure 6 The circumferential positioning structure includes a circumferential positioning groove 317 on the pressure ring seat 350 (e.g., the second housing 312) and a circumferential positioning protrusion 325 on the ball seat 320. The circumferential positioning protrusion 325 is embedded in the circumferential positioning groove 317. The number of circumferential positioning grooves 317 and circumferential positioning protrusions 325 is not limited; there can be one or more. Figure 6 There are four in total. In some other embodiments, a circumferential positioning groove may be provided on the ball seat 320, and a circumferential positioning protrusion may be provided on the pressure ring seat 350.

[0070] Please refer to Figure 6The radial positioning structure includes a radial positioning protrusion 318, which is disposed on the inner sidewall of the pressure ring seat 350 formed by the second housing 312. The radial positioning protrusion 318 is located in the radial gap between the pressure ring seat 350 and the ball seat 320, and can support the radially outer side of the ball seat 320, thereby providing radial positioning for the ball seat 320. In some other embodiments, the radial positioning protrusion 318 may also be disposed on the radially outer side of the ball seat 320.

[0071] Please refer to Figure 4 The axial positioning structure 319 includes a first support surface 351 disposed on the pressure ring seat 350 and a second support surface 326 disposed on the ball seat 320. The first support surface 351 is the lower side surface of the top portion of the second housing 312, and the second support surface 326 is the top surface of the ball seat 320. The first support surface 351 and the second support surface 326 abut against each other along the direction of entry or exit of the trajectory ball 330 in the ball seat 320, thereby achieving axial positioning.

[0072] Those skilled in the art will understand that the central hole of the pressure ring 340 can form a clearance space, allowing the trackball 330 to be exposed. To avoid scratching the trackball 330, the radial inner sidewall of the pressure ring 340 can be an inclined sidewall or an arc-shaped sidewall. This prevents the edge of the pressure ring 340 from contacting the trackball 330, thereby preventing the trackball 330 from rubbing against the edge of the pressure ring 340 when it rotates. The specific shape of the pressure ring 340 is not limited, as long as it can limit the movement of the trackball 330 and prevent the trackball 330 from falling out of the receiving cavity 321.

[0073] As medical devices, ultrasound equipment often requires careful cleaning and disinfection to meet hospital hygiene standards. For the trackball device on the ultrasound equipment control panel 300, the trackball 330, due to its design, is prone to accumulating dust and dirt, which may cause the cursor to become unresponsive or inaccurate. Therefore, the structure near the trackball 330 and its base 320 often needs cleaning. Cleaning the trackball 330, for trackball devices using a rotary latch, typically involves the following steps: 1. Rotate and remove the retaining ring; 2. After removing the retaining ring, remove the trackball 330 itself; 3. Clean the positioning rod or sensor. However, the rotary latching mechanism of the retaining ring is cumbersome to install and remove, and its complex shape makes cleaning inconvenient.

[0074] In one embodiment of this utility model, at least one of the pressure ring 340 and the panel body 310 is magnetic, so as to generate a magnetic attraction between the pressure ring 340 and the panel body 310. The pressure ring 340 is fixed to the panel body 310 by the magnetic attraction. Specifically, the pressure ring 340 is fixed to the pick-and-place port 322 by the magnetic attraction. The pressure ring 340 is detachably fixed to the ball seat 320 by magnetic attraction, and can be directly disassembled by overcoming the magnetic attraction, making disassembly and assembly more convenient. In addition, the outer surface of the pressure ring 340 can be a smooth surface to avoid the inconvenience of cleaning caused by complex structure. It should be noted that at least one of the pressure ring 340 and the ball seat 320 being magnetic means that at least a part of the pressure ring 340 and the ball seat 320 are magnetic, and is not intended to limit it to being magnetic in its entirety. It includes both cases of partial magnetism and overall magnetism.

[0075] In some embodiments, one of the pressure ring 340 and the panel body 310 may include a magnetic attractant 343 or be magnetic itself, and the other may include an attractant 324 that can be attracted by a magnet or be magnetic itself.

[0076] In some other embodiments, both the pressure ring 340 and the panel body 310 include magnetic suction elements 343 or are magnetic themselves, so that the pressure ring 340 can be fixed to the ball seat 320 by magnetic attraction.

[0077] Those skilled in the art will understand that magnetic attractor 343 refers to an object made of magnetic material, such as neodymium iron boron magnet, ferrite magnet, AlNiCo magnet and Samarium Cobalt magnet, which can form a magnetic field; while attractor 324 refers to an object made of material that can be attracted by a magnetic field, such as ferromagnetic materials such as iron, cobalt and nickel or some paramagnetic materials with weak attraction.

[0078] In one specific embodiment, please refer to Figure 1 and Figure 2 The pressure ring 340 is provided with a magnetic element 343, and the panel body 310 is provided with an adsorption element 324. The adsorption element 324 is sheet-shaped and is completely embedded in the panel body 310, for example, embedded in the second shell 312 in the illustrated embodiment. Figure 1 and Figure 2As shown, the second housing 312 can be a composite structure with different layers. Of course, in some other embodiments, the second housing 312 can also be a homogeneous structure formed of a single material. The sheet-like adsorption member 324 can have a relatively thin thickness, which avoids making the corresponding part of the ball seat 320 too thick when embedded in it. The magnetic suction member 343 can be disposed on the pressure ring 340, and can have a thicker thickness than the adsorption member 324, providing a greater magnetic field strength. Furthermore, the pressure ring 340 can be relatively thick, thus facilitating the placement of the magnetic suction member 343. Of course, in some other embodiments, the magnetic suction member 343 can also be a block structure.

[0079] In some embodiments, the magnetic element 343 and / or the adsorption element 324 can be fixed to the corresponding pressure ring 340 or panel body 310 by insert injection molding or overmolding. This avoids separate assembly processes, helps ensure the accuracy of the setting position, and also helps avoid affecting the appearance of the pressure ring 340 or panel body 310. Those skilled in the art should know that injection molding and overmolding are existing processes, both of which belong to multi-material injection molding technology, which can combine different materials into a whole part through one or more injection steps. However, insert injection molding usually involves placing the insert (e.g., magnetic element 343 or adsorption element 324) first and then injecting plastic, while overmolding can be two independent injection molding processes, with the second injection material covering the first molded part, or it can be performed continuously in a two-color injection molding machine to achieve integrated molding of multiple materials.

[0080] In some other embodiments, the magnetic member 343 or the adsorption member 324 can also be fixed in other ways, such as by fixing it to the pressure ring 340 or the panel body 310 through an assembly structure. Specifically, it can be fixedly connected to the pressure ring 340 or the panel body 310 by means of bonding, snap-fit ​​structure, interference fit, fasteners, etc.

[0081] In one embodiment, to ensure reliable positioning of the pressure ring 340, the pressure ring 340 includes a radial positioning portion 341 and an axial positioning portion 342. When the pressure ring 340 is fixed to the panel body 310, the radial positioning portion 341 is positioned along the radial direction of the pressure ring 340 by the inner wall of the pick-and-place opening 322, and the axial positioning portion 342 is positioned along the axial direction of the panel body 310 by the pressure ring 340. Correspondingly, the magnetic suction member 343 on the pressure ring 340 has a first portion 3431 and a second portion 3432, the first portion 3431 being located on the radial positioning portion 341 and the second portion 3432 being located on the axial positioning portion 342. By providing radial positioning portions 341 and axial positioning portions 342, and matching the shape of the pressure ring 340 with the radial positioning portions 341 and axial positioning portions 342, reliable positioning of the pressure ring 340 is achieved, while enabling the magnetic suction member 343 to form a larger magnetic suction range, thereby achieving a greater magnetic suction force and making the pressure ring 340 more reliably fixed to the panel body 310. Those skilled in the art will understand that when the pressure ring 340 is not provided with a magnetic suction member 343 but with a magnetically adsorbable member 324, the adsorbent member 324 may have a first part and a second part, with the first part located on the radial positioning portion 341 and the second part located on the axial positioning portion 342.

[0082] In one embodiment, the first portion 3431 of the magnetic attractor 343 has a protrusion 3433 that extends radially into the ball seat 320 towards the depth of the ball seat 320. The outer peripheral surface of the first portion 3431 is exposed outside the pressure ring 340, thus forming a larger L-shaped mating surface. In another embodiment, the first portion 3431 of the attractor 324 on the pressure ring 340 may also be recessed into the radially positioned portion 341 or flush with the end face of the radially positioned portion 341.

[0083] In one embodiment, please refer to Figure 4 The adsorption member 324 includes a first sheet portion 3241 and a second sheet portion 3242 with an included angle. The first sheet portion 3241 corresponds to the radial positioning portion 341 of the pressure ring 340 along the radial direction of the pressure ring 340, and the second sheet portion 3242 corresponds to the axial positioning portion 342 of the pressure ring 340 along the axial direction of the pressure ring 340. Of course, in some other embodiments, regardless of whether the magnetic adsorption member 343 on the pressure ring 340 has both the first portion 3431 and the second portion 3432, the sheet portion on the ball seat 320 serving as the adsorption member 324 may include only the first sheet portion 3241 or only the second sheet portion 3242.

[0084] In one embodiment, please refer to Figure 2 , Figure 5The magnetic attractor 343 on the pressure ring 340 has an exposed portion that is exposed outside the pressure ring 340 and contacts the panel body 310. This reduces the distance between the magnetic attractor 343 and the adsorption member 324, which also helps to improve the magnetic attraction force. In the above embodiment, the exposed portion of the magnetic attractor 343 includes the outer peripheral surface of the first portion 3431 and the side of the second portion 3432 facing the panel housing 310. In some other embodiments, only the first portion 3431 or only the second portion 3432 may be exposed, and the area of ​​the exposed portion may also vary.

[0085] Additionally, it should be noted that in the above embodiments, the magnetic attracting element 343 and / or the adsorption element 324 can adopt a rotating body structure, that is, a ring structure. In some other embodiments, the magnetic attracting element 343 and / or the adsorption element 324 can also be distributed and arranged in multiple places around the axis of the accommodating cavity 321, and there can be circumferential intervals between each place.

[0086] Furthermore, in some other embodiments, the panel body 310 is a plastic magnetic component or has a plastic magnetic portion, and / or, the retaining ring 340 is a plastic magnetic component to make itself magnetic. For example, the retaining ring 340 and / or the retaining ring connection portion 323 can be plastic magnetic components to make themselves magnetic. Those skilled in the art will understand that a plastic magnetic component is an object formed using a plastic magnetic process, such as incorporating magnetic powder into plastic injection molding raw materials to achieve magnetism; this technique is also known as injection molding magnetism or plastic magnetic molding. Specifically, as some examples, magnetic powder (such as ferrite, neodymium iron boron NdFeB, samarium cobalt SmCo, or samarium iron nitrogen SmFeN, etc.) can be mixed with thermoplastic resins (such as nylon 6, nylon 12, PPS, etc.) and other possible additives, and then this mixture can be injected into a mold using an injection molding process.

[0087] In some other embodiments, at least one of the pressure ring 340 and the panel body 310 may include an electromagnetic generator for blocking the magnetism of the trackball 330, which is generated by the electromagnetic generator. Those skilled in the art will understand that the electromagnetic generator may be an electromagnet, such as an electromagnet formed by an iron core and a coil wound around the iron core. When the coil is energized, it generates a magnetic field that can be concentrated in the iron core to achieve a large magnetic attraction force.

[0088] When it is necessary to remove the pressure ring 340, if the pressure ring 340 protrudes from the panel body 310, force can be applied directly to the protruding part of the pressure ring 340 to remove it. However, for easier removal of the pressure ring 340, in some embodiments, please refer to... Figure 1 and Figure 2The ball seat 320 has an opening 3201, through which the trackball 330 is partially exposed when inserted into the ball seat 320. A ball-retrieving structure connected to the opening 3201 is provided on the second side of the panel body 310. This structure applies a force to the trackball 330 through the opening, causing it to move outwards towards the retrieval opening 322. This allows the user to more easily remove the trackball 330 by applying force through the ball-retrieving structure.

[0089] In one specific embodiment, an operation hole 3111 is provided on the side of the panel body 310 opposite to the side with the pick-up and drop-out opening 322, i.e., an operation hole 3111 is provided on the second side. The operation hole 3111 communicates with the opening 3201 and is used to apply a force to the trackball 330 from the opening 3201 to move the trackball 330 toward the outside of the pick-up and drop-out opening 322. For example, the user can insert a finger into the operation hole 3111 to push the trackball 330 and the pressure ring 340 away from the panel body 310.

[0090] In some other embodiments, the ball-retrieving structure can be replaced with other structures. For example, the ball-retrieving structure may include a button disposed on the second side of the panel body 310, the button communicating with the opening 3201, for applying a force from the opening 3201 to the trackball 330, causing the trackball 330 to move outward toward the pick-up / drop-off port 322. In one specific embodiment, the button may be disposed within the operation hole 3111. Those skilled in the art will understand that the button is movably disposed on the panel body; for example, a guide structure may be provided on the panel body 310 to allow the button to move along the direction in which the trackball 330 enters and leaves the ball seat 320, and a limiting structure may be provided between the panel body 310 and the button to prevent the button body from detaching from the panel body 310 on its own. Those skilled in the art will understand that the above-mentioned guide structure and limiting structure can refer to existing structures in related technologies, and will not be described in detail here. Furthermore, a flexible membrane may be disposed between the button and the edge of the operation hole 3111, and the movement of the button is achieved by the deformation of the flexible membrane. In some other embodiments, the ball-retrieving structure may also be a variable membrane structure.

[0091] In some embodiments, the opening 3201, the trackball, and the pick-and-place port 322 are arranged in a straight line, which makes it easier for the user to apply driving force to the trackball. In some other embodiments, at least one of the opening 3201, the trackball 330, and the pick-and-place port 322 may be partially offset relative to the other two in a direction perpendicular to the direction in which the trackball 330 enters and leaves the ball seat 320.

[0092] For the panel body 310 equipped with a rotating buckle 3162, a magnetic attraction structure can also be implemented. In one embodiment, please refer to... Figure 7 and Figure 8The panel body 310 includes a base portion and an adapter ring 316. The adapter ring 316 is fixed to the base portion by a snap-fit ​​structure, and a pressure ring 340 is disposed on the adapter ring 316. By providing the adapter ring 316, it can be fixed to the control panel of the ultrasonic equipment and does not need to be removed under normal circumstances. Simultaneously, the adapter ring 316 forms part of the panel body 310 and can be magnetic, allowing the pressure ring 340 to be installed using a magnetic attraction structure. It is fixed to the adapter ring 316 by magnetic attraction, enabling easy disassembly. In some other embodiments, the adapter ring 316 can also be provided with magnetic or adsorption components, and the pressure ring 340 can correspondingly be provided with adsorption or magnetic components.

[0093] As an example, in one specific embodiment, the adapter ring 316 may include a ring body 3161 and a buckle 3162. The buckle 3162 may have the same structure as the buckle 3162 on the pressure ring 340 with a rotary buckle 3162 in the prior art, which will not be described in detail here.

[0094] In some embodiments, the gap between the pressure ring 340 and the trackball 330 is small, which can maintain the stable movement of the trackball 330 and prevent dust from entering the interior of the trackball 330 device. However, in some other embodiments, the ultrasonic equipment control panel may also include a dustproof component to further improve the dustproof effect.

[0095] In one embodiment, the dustproof component has a dustproof adapter surface, the position of which can be the same as the radial inner surface of the radial positioning part 341, with the dustproof adapter surface facing the trackball 330. The dustproof adapter surface can be an annular conical surface or an annular spherical surface, enabling quick alignment with the trackball 330. The dustproof adapter surface is used to conform to the surface of the trackball 330, thereby achieving a dustproof effect. For example, the gap between the dustproof adapter surface and the trackball 330 can be no greater than 1 mm, thereby preventing dust particles larger than 1 mm from entering the trackball 330 device. Of course, the gap between the dustproof adapter surface and the trackball 330 can also be 0, keeping the dustproof adapter surface in contact with the trackball 330, achieving a more complete dustproof effect.

[0096] In one specific embodiment, the dustproof component may include an annular cover and a support member. The annular cover is used to conform to the surface of the trackball 330, and the dustproof adapter surface is disposed on the annular cover. The support member is disposed between the annular cover and the panel body, and the support member is made of rigid or elastic material. In particular, when the gap between the dustproof adapter surface and the trackball 330 is zero, a support member made of elastic material is beneficial in eliminating the gap between the dustproof adapter surface and the trackball 330 while preventing the trackball 330 from being excessively compressed and stuck by the pressure ring 340. As an example, the elastic material that the support member can use can be elastic cotton, silicone, polyurethane, etc. In addition, the support member can be a single annular unit or multiple circumferentially distributed elastic bodies. For ease of assembly, the support member can be fixed to the base portion of the pressure ring 340 and / or the annular cover.

[0097] In the above embodiments, the control panel of the ultrasonic equipment prevents the trackball 330 from detaching from the ball seat 320 via the pressure ring 340. In some other embodiments, at least one of the panel body 310 and the trackball 330 may be magnetic to generate a magnetic attraction between the trackball 330 and the panel body 310. This magnetic attraction is used to prevent the trackball 330 from detaching from the ball seat 320 when it is embedded in the ball seat 320, thereby embedding the trackball 330 into the ball seat 320.

[0098] In some specific embodiments, the trackball 330 can be attracted by a magnet, acting as an adsorption element itself. The panel body 310 includes a magnetic adsorption element and / or an electromagnetic generator, or the panel body 310 itself is magnetic. Specific methods for making the panel body 310 magnetic can be referred to the above embodiments. Those skilled in the art will understand that in some other embodiments, the panel body 310 can also be attracted by a magnet, and the trackball 330 includes a magnetic adsorption element and / or an electromagnetic generator, or the trackball 330 itself is magnetic. Exemplarily, the trackball 330 can be made of a plastic magnetic element. Additionally, when the trackball 330 can be attracted by a magnet, for example, when the trackball 330 uses an iron ball as its body, the outer surface of the iron ball can be coated with a protective layer formed of silicone, plastic, phenolic resin, polyurethane (PU), polyoxymethylene (POM), nylon (PA), polypropylene (PP), or other engineering plastics, or metal.

[0099] When the magnetic attraction between the trackball 330 and the panel body 310 is used to prevent the trackball 330 from detaching from the ball seat 320, the trackball 330 can also enter or detach from the ball seat 320 through the pick-and-place port 322 located on one side of the panel body 310. When the trackball 330 is embedded in the ball seat 320, the pick-and-place port 322 matches the corresponding part of the trackball 330, thereby avoiding an excessive gap between the trackball 330 and the ball seat 320, which helps to prevent foreign objects from entering.

[0100] In some embodiments, the smallest portion of the inner diameter of the pick-and-place port 322 is smaller than the diameter of the trackball 330, and the trackball 330 and / or the pick-and-place port 322 can elastically deform to allow the trackball 330 to enter or exit the ball seat 320. In one specific embodiment, the inner wall of the pick-and-place port 322 is provided with protrusions distributed circumferentially along the pick-and-place port 322, and the protrusions are used to form the smallest portion of the inner diameter of the pick-and-place port. The protrusions can be dot-shaped protrusions, linear protrusions, etc. In some other embodiments, the receiving cavity 321 of the ball seat 320 can be larger than a hemisphere, such that the smallest portion of the inner diameter of the pick-and-place port 322 is smaller than the diameter of the trackball 330.

[0101] In the case where the trackball 330 itself is magnetic, to facilitate the removal of the trackball 330, similar to the embodiment using a pressure ring, the ball seat 320 may have an opening 3201. When the trackball 330 is embedded in the ball seat 320, it is partially exposed to the opening 3201. An operating hole 3111 is provided on the panel body 310 opposite to the side with the pick-up / placement opening 322. The operating hole 3111 communicates with the opening 3201 and is used to apply a force to the trackball 330 from the opening 3201, causing the trackball 330 to move towards the outside of the pick-up / placement opening 322. The specific structure of the operating hole 3111 can be the same as in the embodiment using a pressure ring 340, and will not be described again here.

[0103] The control panel of the ultrasonic equipment can have the same structure as the control panel of the ultrasonic equipment in any of the above-described embodiments of the ultrasonic equipment, and will not be described again here.

[0104] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
