DETAILED DESCRIPTION

[0038] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative rather than limiting.

[0039] In describing the present invention, it should be understood that in the embodiments shown in the accompanying drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are merely for the purpose of facilitating the description of the present invention and simplifying the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. These descriptions are appropriate when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components change, the indications of these directions will also change accordingly.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] In actual use, the buttons on ultrasound devices come in a variety of shapes and styles, making them difficult to standardize. Furthermore, the different types of buttons also have different operating feel, which impacts the user experience and makes it difficult to meet the specific needs of different users.

[0042] The reasons for the different specific requirements for buttons are also diverse, as follows:

[0043] 1) Differences among user groups: For example, older doctors are accustomed to the feel of buttons with high force, long travel, and clear feedback; while younger doctors prefer the delicate feel of buttons with low force and short travel.

[0044] 2) Differences in button usage functions: For example, mode buttons B, C, and PW that are not frequently used need a heavier feedback feel, while frequently used FREEZE and MEASURE buttons need a lighter feel to avoid fatigue;

[0045] 3) The evaluation of key feel cannot be quantified, and individual experience varies greatly. Different users cannot provide specific and quantified experience feedback on key operation, which is highly subjective.

[0046] 4) Differences in usage requirements. For example, laptop ultrasound systems, in addition to standard bedside use, are now also used in operating rooms. The two have different requirements for keypad waterproofing, with the latter requiring more stringent waterproofing than the former.

[0047] The above reasons result in ultrasonic buttons being unable to meet the needs of different operators or operating scenarios, thereby affecting the user experience of ultrasonic equipment. Therefore, a button module for ultrasonic equipment is proposed to solve the above problems.

[0048] The scheme is further illustrated by the following examples:

[0049] Figure 1 Schematic diagram of an ultrasonic device and a key module according to an embodiment of the present invention. Figure 2 yes Figure 1 Schematic diagram of the exploded view of the ultrasonic device and button module. Figure 3 yes Figure 1 A partial cross-sectional view of the ultrasonic device and button module.

[0050] See also Figure 1 、 Figure 2 and Figure 3 The ultrasound device of this embodiment may include a panel housing 10 , a control panel 11 and a button module 20 .

[0051] Specifically, the control panel 11 is installed on the panel shell 10, and the panel shell 10 is provided with a accommodating cavity 12 with one side open. The button module 20 is adapted to the accommodating cavity 12, so that the button module 20 can be accommodated in the accommodating cavity 12, and then the button module 20 can be detachably connected in the accommodating cavity 12.

[0052] It should be noted that the ultrasound device can be provided with multiple button modules 20, and each button module 20 can be configured in different styles, allowing users to select the corresponding button module 20 according to their needs, thereby meeting the personalized needs of different users. At the same time, because the button module 20 is detachably connected to the panel housing 10, while meeting personalized needs, the button module 20 can also be quickly replaced, thereby improving the user experience.

[0053] In this embodiment, the ultrasound device may also be provided with a display panel 1 and a key panel 2 to facilitate user use and operation.

[0054] Figure 4 yes Figure 1 Schematic diagram of the button module. Figure 5 yes Figure 4 Cross-sectional view at AA.

[0055] See Figure 3 、 Figure 4 and Figure 5 The key module 20 of this embodiment can be connected to the main body of the ultrasound device, so that the user can control different functions of the ultrasound device through the key module 20.

[0056] Specifically, the button module 20 may include a button housing 21 , a button assembly 22 , a transmission assembly 23 and a connector 24 .

[0057] The button housing 21 can abut against the ultrasonic device, allowing the entire button module 20 to be connected to the ultrasonic device. It should be noted that the shape of the button housing 21 is compatible with the shape of the accommodating cavity 12, allowing the button housing 21 to be accommodated within the accommodating cavity 12, thereby enabling the button module 20 to be connected to the ultrasonic device. Of course, in other embodiments, the button housing 21 can be directly attached to the panel housing 10 of the ultrasonic device, and the button module 20 can be connected to the panel housing 10 via a connector, thereby achieving a detachable connection between the button module 20 and the ultrasonic device.

[0058] In this embodiment, the button housing 21 may be provided with a main housing 212 and a bottom housing 213 , and the bottom housing 213 is connected to the bottom of the main housing 212 by screws, and a button cavity 211 is formed between the main housing 212 and the bottom housing 213 .

[0059] The connector 24 is disposed within the key cavity 211 and is located on the side of the key housing 21 facing the main body of the ultrasonic device. That is, the connector 24 is connected to the bottom housing 213. The connector 24 corresponds to the adsorption member 14 on the control panel 11, allowing the connector 24 to be attached to or detached from the adsorption member 14, thereby allowing the key housing 21 to be detachably connected to the ultrasonic device.

[0060] Specifically, when the adsorbent 14 and the connecting member 24 are adsorbed, the key module 20 can be closely attached to the panel housing 10, that is, the key module 20 is in contact with or connected to the ultrasonic device. When the adsorbent 14 and the connecting member 24 are separated, the key module 20 can be separated from the panel housing 10, thereby allowing the key module 20 to be detached from the ultrasonic device.

[0061] In this embodiment, the adsorption member 14 can be configured as an electromagnet, which is fixed to the control panel 11 and electrically connected to the control panel 11, so that the electromagnet can be turned on or off under the control of the control panel 11. At the same time, the connecting member 24 can be configured as a magnetic member. Specifically, the connecting member 24 can be a permanent magnet, such as a magnet, so that the electromagnet can be connected to the magnetic member through magnetic attraction.

[0062] Specifically, when the electromagnet is energized and turned on, the electromagnet generates electromagnetic force and connects the magnetic element through magnetic adsorption, so that the button housing 21 is firmly connected to the ultrasonic device, thereby making the button module 20 tightly attached to the panel housing 10.

[0063] When the electromagnet is turned off, it does not generate magnetic force, allowing the electromagnet to separate from the magnetic attraction member, thereby allowing the key housing 21 to be separated from the ultrasonic device, and further allowing the key module 20 to be separated from the panel housing 10. Therefore, through the magnetic attraction or separation between the attraction member 14 and the connection member 24, the key module 20 can be detachably connected to the panel housing 10 or the ultrasonic device.

[0064] It should be noted that the magnetic field generated by the electromagnet after being energized is compatible with the magnetic field of the magnet, so that the electromagnet and the magnet can attract each other through opposite charges, thereby enabling the adsorption component 14 to adsorb the connecting component 24.

[0065] In other embodiments, the control panel 11 can control the direction of the magnetic field of the adsorbent 14 by changing the direction of the current flowing through the electromagnet. When the key module 20 needs to be placed firmly against the panel housing 10, the magnetic field direction of the adsorbent 14 is aligned with the magnetic field direction of the connector 24, so that the adjacent magnetic poles of the two poles are opposite in polarity, thereby causing the two poles to attract each other, thereby firmly connecting the key module 20 to the panel housing 10. When the key module 20 needs to be pushed out of the accommodating cavity 12, the control panel 11 programmatically controls the direction of the current flowing through the adsorbent 14 to reverse, so that the magnetic field generated by the adsorbent 14 and the magnetic field of the connector 24 are opposite in polarity, thereby causing the adjacent magnetic poles of the two poles to be the same in polarity, thereby causing the two poles to repel each other, allowing the adsorbent 14 to push the connector 24 away from the accommodating cavity 12, thereby pushing the key module 20 out of the accommodating cavity 12 and facilitating its removal.

[0066] In some other embodiments, the adsorption member 14 and the connecting member 24 may be configured as two Velcro strips that can be adsorbed onto each other, so that the adsorption member 14 and the connecting member 24 can be detachably connected.

[0067] Of course, the adsorption member 14 can also be set as a snap-fit ​​structure, and the connecting member 24 can be set as a snap-fit ​​structure. The adsorption member 14 and the connecting member 24 can be snap-fitted, so that the button module 20 can be detachably connected to the panel housing 10 or the ultrasonic device.

[0068] Figure 6 yes Figure 1 Exploded view of the button module.

[0069] See Figure 4 、 Figure 5 and Figure 6 The key assembly 22 can be installed on the key cavity 211 and can move relative to the key housing 21. Specifically, the key assembly 22 partially extends out of the key cavity 211, so that the user can move the key assembly 22 relative to the key housing 21 by pressing the key assembly 22.

[0070] Specifically, the key assembly 22 may include a key cap 221 and a restoring member 222 .

[0071] The key cap 221 is connected to the key housing 21 and can move relative to the key housing 21 , thereby moving between an initial position and a pressed position.

[0072] In this embodiment, a through hole 214 is formed on the side of the main housing 212 facing away from the bottom housing 213 , so that the key cap 221 can partially extend out of the key housing 21 through the through hole 214 , so that the user can operate the key cap 221 .

[0073] It should be noted that the key cap 221, through hole 214 and reset member 222 can be provided in multiple numbers, so that different key caps 221 can input different control signals and thus control different functions of the ultrasound device. In this embodiment, multiple reset members 222 can also be provided in an integrated manner.

[0074] At the same time, the reset member 222 is connected between the key housing 21 and the key cap 221 to drive the key cap 221 to reset from the pressed position to the initial position.

[0075] It should be noted that the pressed position can be set to the trigger control or trigger input position of the key assembly 22, that is, the open position of the key assembly 22. The initial position can be set to a position away from the pressed position, that is, the closed position of the key assembly 22.

[0076] At the same time, the reset member 222 is configured as any one of a silicone member, a spring member or a pot piece, so that the reset member 222 can drive the button cap 221 to reset from the pressed position to the initial position.

[0077] It should be noted that, since the reset member 222 can be made of different materials, the pressing force required when pressing the key cap 221 is different. Therefore, by setting the reset member 222 of different materials, the operating habits and operating requirements of different operators can be met.

[0078] At the same time, since the key cap 221 needs to overcome the resistance of the reset member 222 before it can move from the initial position to the pressed position to realize the pressing function, the key stroke of the key cap 221 can be changed by setting the reset member 222 to different strokes, thereby adapting to the operating habits and operating needs of different operators.

[0079] In addition, the key cap 221 is configured as any one of a translucent key cap, a plastic key cap, or a silicone key cap to meet the operating habits and operating requirements of different operators. Of course, the key cap 221 can also be configured with different materials or different surface treatments to meet different personalized needs.

[0080] Figure 7 yes Figure 1 Schematic diagram of the bottom of the button module. Figure 8 yes Figure 1 Schematic diagram of the contact switch of the key module. Figure 9 yes Figure 1 Schematic diagram of the electrical connector of the key module.

[0081] See Figure 2 、 Figure 3 and Figure 7 The transmission component 23 can be set in the key cavity 211 and connected to the key component 22. At the same time, the transmission component 23 is used to electrically connect to the control panel 11. When the key component 22 moves toward the bottom of the key cavity 211, the control panel 11 can recognize the pressing of the key component 22 through the transmission component 23. That is, the key module 20 is electrically connected to the control panel 11 through the transmission component 23, so that when the key cap 221 is pressed by the user, the control panel 11 can recognize the pressing of the key component 22 through the transmission component 23 and enable the control panel 11 to recognize the corresponding control signal.

[0082] This enables the control panel 11 or the control center to control the ultrasound device to run corresponding functions according to the control signal, thereby enabling the user to control the ultrasound device to run corresponding functions through the key module 20 .

[0083] See Figure 3 、 Figure 6 and Figure 7 The transmission component 23 may include a key PCB board 231 and a contact switch 232.

[0084] Specifically, a key PCB 231 is mounted within the key cavity 211, and a contact switch 232 is provided on the key PCB 231, corresponding to the key assembly 22. When the key assembly 22 moves toward the bottom of the key cavity 211, the key assembly 22 can control the contact switch 232 to be turned on. Furthermore, an electrical connection portion 233 is provided on the side of the key PCB 231 facing away from the contact switch 232. The electrical connection portion 233 is used to connect to the control panel 11, electrically connecting the key PCB 231 to the control panel 11. When the contact switch 232 is turned on, the control panel 11 can recognize that the key assembly 22 is in the pressed state.

[0085] Therefore, after the key cap 221 is pressed, the contact switch 232 is turned on, and the signal of the contact switch 232 being turned on is transmitted to the control panel 11 through the key PCB board 231 and the electrical connection part 233, so that the control panel 11 recognizes that the key cap 221 is pressed and controls the ultrasound equipment to perform the corresponding function.

[0086] In this embodiment, an electrical connector 13 may be provided on the control panel 11. The electrical connector 13 protrudes from the control panel 11, and one end of the electrical connector 13 away from the control panel 11 extends into the accommodating cavity 12. When the key module 20 is connected to the accommodating cavity 12, the end of the electrical connector 13 away from the control panel 11 can abut against the key PCB board 231 and electrically connect the key PCB board 231, thereby conducting electricity between the control panel 11 and the key PCB board 231, and thus electrically connecting the key PCB board 231 and the control panel 11, allowing the control panel 11 to receive the on / off signal of the contact switch 232, thereby allowing the control panel 11 to recognize the pressing or rebound of the key cap 221.

[0087] See Figure 8 The contact switch 232 may include a conductive member 234 and two abutting members 235. The two abutting members 235 are spaced apart on the key PCB 231. The conductive member 234 is connected to the key assembly 22. Specifically, the conductive member 234 may be connected to the reset member 222. Driven by the key assembly 22, the conductive member 234 can move toward or away from the key PCB 231.

[0088] In this embodiment, when the conductive member 234 moves toward the key PCB 231, it can simultaneously abut the two abutting members 235, causing the two abutting members 235 to conduct electricity through the conductive member 234 and turning on the contact switch 232. When the conductive member 234 moves away from the key PCB 231, the conductive member 234 separates from the two abutting members 235, disconnecting the two abutting members 235 and turning off the contact switch 232.

[0089] It should be noted that the conductive member 234 and the two abutting members 235 are both configured as conductive metal members.

[0090] See Figure 9 The electrical connector 13 may include an electrical connector seat 131 , an electrical connector cap 132 and an elastic member 133 .

[0091] The electrical connector 131 is fixed to the control panel 11, and the electrical connector cap 132 is connected to the electrical connector 131 and can move relative to the electrical connector 131 to abut against the electrical connector portion 233 of the key PCB 231, thereby electrically connecting the key PCB 231 to the control panel 11. Furthermore, an elastic member 133 is connected between the electrical connector 131 and the electrical connector cap 132. The elastic member 133 can drive the electrical connector cap 132 to move away from the electrical connector 131. After the suction member 14 is separated from the connector 24, the elastic member 133 can drive the key module 20 to move away from the accommodating cavity 12, thereby pushing the key module 20 out of the accommodating cavity 12 and facilitating removal of the key module 20.

[0092] In this embodiment, multiple electrical connectors 13 are provided, and the multiple electrical connectors 13 are spaced apart on the control panel 11, thereby ensuring a stable electrical connection between the key PCB 231 and the control panel 11. Furthermore, the multiple electrical connectors 13 can also provide sufficient thrust to push the key module 20 out of the accommodating cavity 12.

[0093] It should be noted that after the button module 20 is placed in the accommodating cavity 12, when the adsorption part 14 is connected to the connecting part 24 through magnetic adsorption, it can drive the button module 20 to overcome the resistance generated by the elastic part 133 of the electrical connector 13, so that the button module 20 can be firmly connected in the accommodating cavity 12.

Figure 11 yes Figure 10 A partial cross-sectional view of the ultrasonic device and button module. Figure 12 yes Figure 10 Exploded view of the button module.

[0095] See Figure 10 、 Figure 11 and Figure 12 In this embodiment, the button module 20 may include a button housing 21 , a button assembly 22 , a transmission assembly 23 and a connector 24 .

[0096] The transmission component 23 can be configured as a magnetic component 31 capable of generating a magnetic field. The magnetic component 31 is connected to the button component 22 and is configured corresponding to the Hall sensor 32 on the control panel 11, so that the Hall sensor 32 can sense the magnetic field of the magnetic component 31.

[0097] Specifically, driven by the button assembly 22, the magnetic part 31 can move toward the Hall sensor 32 or away from the Hall sensor 32, that is, the button assembly 22 can drive the magnetic part 31 to move toward or away from the Hall sensor 32, so that the Hall sensor 32 can sense or identify the change in the distance of the magnetic part 31 relative to itself.

[0098] In this embodiment, when the magnetic member 31 moves toward the Hall sensor 32 and the distance between the magnetic member 31 and the Hall sensor 32 is less than a preset value, the Hall sensor 32 can recognize that the button assembly 22 is pressed through the magnetic member 31, and the Hall sensor 32 can transmit a corresponding signal to the control panel 11, so that the control panel 11 can control the ultrasound device to perform the corresponding function based on the signal. When the magnetic member 31 moves away from the Hall sensor 32 and the distance between the magnetic member 31 and the Hall sensor 32 is equal to or greater than the preset value, the Hall sensor 32 recognizes that the button assembly 22 has returned to its initial position.

[0099] It should be noted that since the key module 20 and the control panel 11 are not connected by electrical wires, the key module 20 can be independently installed from the panel housing 10 and the control panel 11, facilitating waterproof installation. Furthermore, this connection method can prevent wear and tear on the cable connection during use, thereby extending the service life of the key module 20.

[0100] Furthermore, in this embodiment, multiple Hall sensors 32 and magnetic members 31 are provided, and each Hall sensor 32 and magnetic member 31 is provided in a one-to-one correspondence, thereby preventing interference between individual Hall sensors 32 or magnetic members 31. Furthermore, each set of magnetic members 31 and Hall sensors 32 is provided corresponding to a keycap 221, allowing different keycaps 221 to input different control signals.

[0101] In addition, it should be noted that when the button module 20 is electrically connected to the control panel 11 through the Hall sensor 32 and the magnetic part 31, an elastic part can be arranged between the button module 20 and the panel shell 10, so that when the adsorption part 14 is separated from the connecting part 24, the elastic part can drive the button module 20 out of the accommodating cavity 12, thereby facilitating the disassembly and replacement of the button module 20.

[0102] In summary, the button module 20 can be connected to the ultrasonic device, and the button module 20 includes a button housing 21, a button assembly 22, a transmission assembly 23 and a connector 24. Among them, the button housing 21 can abut against the ultrasonic device, and a button cavity 211 is formed in the button housing 21. The button assembly 22 and the transmission assembly 23 are both arranged in the button cavity 211, and the button assembly 22 can move relative to the button housing 21. The transmission assembly 23 is connected to the button assembly 22 and is electrically connected to the control panel 11 of the ultrasonic device. When the button assembly 22 moves toward the bottom of the button cavity 211, the control panel 11 can recognize the pressing of the button assembly 22 through the transmission assembly 23, so that the user can control the corresponding function.

[0103] At the same time, the connecting part 24 is arranged in the button cavity 211 and is located on the side of the button shell 21 facing the main body of the ultrasonic device, and the adsorption part 14 on the control panel 11 is correspondingly arranged, so that the connecting part 24 can be adsorbed or separated from the adsorption part 14, so that the button shell 21 can be detachably connected to the ultrasonic device, and then the button module 20 can be detachably connected to the ultrasonic device.

[0104] Furthermore, since the button module 20 is detachably connected to the ultrasound device, by setting different button modules 20, users can select different button modules 20 according to their actual needs and connect them to the ultrasound device, thereby meeting the personalized needs of different users.

[0105] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are intended to be illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
