Detailed Implementation
[0028] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.
[0030] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0031] Ultrasound equipment control panels feature buttons of various shapes and sizes, trackballs, and other operating components. Currently, frequently used buttons tend to be concentrated around the trackball, and there's a trend towards larger button areas for easier operation by medical staff. However, most existing large buttons use a cantilever structure, meaning only one side can be pressed, preventing the button from being activated by pressing every corner. Others use a perimeter-limited design, which is prone to wobbling and jamming during use. Furthermore, the current design offers poor operation and a negative user experience.
[0032] Existing ultrasound equipment is widely used in the medical field. Through ultrasound detection, data and morphology of physiological or tissue structures can be obtained, and diseases can be detected. Ultrasound equipment includes an ultrasound probe, a main unit, a control panel, and a display screen. The ultrasound probe is used to transmit and receive ultrasound signals. The main unit is electrically connected to the ultrasound probe. The control panel is electrically connected to the main unit. The display screen is electrically connected to the main unit and is used to display data results.
[0033] Figure 1 This is a schematic diagram of the structure of the ultrasonic equipment control panel 10 provided by this utility model in one embodiment.
[0034] See Figure 1 As shown, this application provides a control panel 10 for an ultrasound device, which is electrically connected to the device's main unit for controlling the operation of the ultrasound device. The control panel 10 includes a panel 1, keycaps 2, resilient buttons 3, and a balance bar 4.
[0035] In some embodiments, panel 1 may be plate-shaped. Keycaps 2 may be disposed on panel 1. Panel 1 may have a keyless area. The keyless area may be disposed on the side of keycap 2 closer to the user. The keyless area may be disposed at the end of panel 1 closer to the user to support the user's wrist and facilitate user operation.
[0036] In some embodiments, multiple keycaps 2 may be provided. These multiple keycaps 2 may be spaced apart on the panel 1 and located on the side away from the user from the buttonless area. The multiple keycaps 2 have different functions, enabling the user to control the ultrasound device via multiple buttons. A touchscreen display is located on the upper side of the panel 1 for touch-sensitive display.
[0037] In some embodiments, the panel 1 may include a PCB board 5. The PCB board 5 may be located below the keycap 2. When a user presses the keycap 2, the keycap 2 can descend and abut against the PCB board 5, thereby triggering the function of the key through the PCB board 5.
[0038] In some embodiments, the multiple keycaps 2 can be of different shapes. Keycaps 2 of different shapes can have different functions. Thus, users can quickly understand the function of the keycaps 2 based on their different shapes, thereby improving the efficiency and accuracy of user operation.
[0039] It should be noted that multiple keycaps 2 can be in the shape of a long strip, a circle, or other irregular shapes, and there are no restrictions here.
[0040] It should be noted that in some other embodiments, multiple keycaps 2 may also have the same shape. The sizes of the multiple keycaps 2 may differ. Keycaps 2 of different sizes may have different functions. Therefore, users can quickly understand the function of a keycap based on its size, thereby improving the efficiency and accuracy of user operation.
[0041] In some embodiments, the spring-loaded button 3 may be located on the panel 1. The spring-loaded button 3 may be located below the keycap 2. The spring-loaded button 3 may be located between the panel 1 and the keycap 2. The spring-loaded button 3 may be elastic. The spring-loaded button 3 may be located above the PCB board 5. When the keycap 2 is pressed, the keycap 2 descends towards the panel 1, pressing the spring-loaded button 3 downwards, thus abutting against the PCB board 5, thereby triggering the button's function through the PCB board 5. When the keycap 2 is released, the spring-loaded button 3 can bounce the keycap 2 back, causing the keycap 2 to rise away from the panel 1, allowing the keycap 2 to reset for the user's next press.
[0042] In some embodiments, the keycap 2 has a protruding contact 31 facing the elastic keycap 3. The contact 31 can be arranged directly opposite the elastic keycap 3. When the keycap 2 is pressed, the keycap 2 can move the contact 31 towards the panel 1, and the contact 31 can press the elastic keycap 3 downward, thereby abutting against the PCB board 5 and triggering the key's function. When the keycap 2 is released, the elastic keycap 3 can rebound the contact 31, causing the keycap 2 to rise away from the panel 1, so that the keycap 2 returns to its original position for the user to press again.
[0043] In some embodiments, the panel 1 has a button cluster area formed by multiple keycaps 2. The button cluster area may be located in the central area of the panel 1. The button cluster area includes a trackball and keycaps 2 disposed around the trackball. The trackball is located at the center of the panel 1 in the left-right direction. The distance from the center of the trackball to the lower edge of the touch screen is less than 180mm. This allows the user to operate the control buttons in multiple button areas on the panel 1 with one hand when the middle of the user's palm is on the trackball, thereby simplifying the operation steps, reducing the intensity of hand joint movement, reducing the amplitude and frequency of arm swing, facilitating operator operation, and improving operator work efficiency.

[0045] Please see Figures 1 to 4 As shown, in some embodiments, the stabilizer bar 4 can be disposed on the panel 1. The stabilizer bar 4 can be disposed below the keycap 2. The panel 1 can be recessed with a mounting groove 11. The stabilizer bar 4 can be disposed within the mounting groove 11. The stabilizer bar 4 is used to ensure that the longer keycap 2 is pressed with even force, avoiding wobbling or key jamming, thereby providing a consistent feel and a more stable typing experience.
[0046] Specifically, the stabilizer bar 4 may include a first stabilizer bar 41 and a second stabilizer bar 42. The first stabilizer bar 41 may include a first main body 411 and two first extension arms 412 connecting the two ends of the first main body 411. The first main body 411 may be rod-shaped. The first main body 411 is rotatably mounted on the panel 1. The two first extension arms 412 are symmetrically disposed on both sides of the elastic key 3, and the first extension arms 412 are connected to the keycap 2. The second stabilizer bar 42 may include a second main body 421 and two second extension arms 422 connecting the two ends of the second main body 421. The second main body 421 may be rod-shaped. The second main body 421 is rotatably mounted on the panel 1. The two second extension arms 422 are symmetrically disposed on both sides of the elastic key 3, and both second extension arms 422 are connected to the keycap 2. One side of the elastic button 3 has a first extension arm 412 and a second extension arm 422, and the other side of the elastic button 3 has another first extension arm 412 and another second extension arm 422. The two first extension arms 412 and the two second extension arms 422 are arranged symmetrically and staggered, with the first extension arm 412 and the second extension arm 422 on one side of the elastic button 3 intersecting. Therefore, the first extension arms 412 and the second extension arms 422 allow for a more comprehensive connection between the keycap 2 and the panel 1, enabling the user to trigger the key function by pressing the keycap 2 at any position. Simultaneously, when the elastic button 3 rebounds, the two balance bars 4 ensure even force distribution on the large keycap 2, allowing for smooth movement of the keycap 2 and preventing wobbling or jamming, thereby improving the user experience.
[0047] Please see Figure 4 As shown, in some embodiments, a first pivot seat 12 may be provided on the panel 1. The first pivot seat 12 has a first pivot hole 121 inside. The first pivot seat 12 may be provided on one side of the elastic button 3. The first main body 411 is rotatably disposed in the first pivot hole 121, and the rotation of the first main body 411 on the panel 1 is realized through the first pivot hole 121.
[0048] In some embodiments, multiple first pivot seats 12 may be provided. Multiple first pivot seats 12 may be spaced apart on one side of the elastic button 3. Multiple first pivot seats 12 may be spaced apart along the axial direction of the rotation axis of the first main body 411. By simultaneously rotating the first main body 411 within multiple first pivot seats 12, the stability of the rotation of the first main body 411 within the first pivot seats 12 can be improved.
[0049] In some embodiments, a second pivot seat 13 may be provided on the panel 1. The second pivot seat 13 has a second pivot hole 131 inside. The second pivot seat 13 may be provided on one side of the elastic button 3. The second main body 421 is rotatably disposed in the second pivot hole 131, and the second main body 421 can rotate on the panel 1 through the second pivot hole 131.
[0050] In some embodiments, multiple second pivot seats 13 may be provided. Multiple second pivot seats 13 may be spaced apart on one side of the elastic button 3. Multiple second pivot seats 13 may be spaced apart along the axial direction of the rotation axis of the second main body 421. By simultaneously rotating the second main body 421 within multiple second pivot seats 13, the stability of the rotation of the second main body 421 within the second pivot seats 13 can be improved.
[0051] Figure 5 This is a structural diagram of keycap 2. Figure 6 yes Figure 5 A structural diagram from another perspective.
[0052] Please see 5 and Figure 6 As shown, in some embodiments, the bottom surface of the keycap 2 is provided with two spaced-apart first sliding seats 21. The two first sliding seats 21 can be respectively provided on both sides of the elastic key 3. The bottom surface of the first sliding seat 21 is provided with an upwardly extending first sliding groove 211. The first sliding groove 211 can be provided above the panel 1. The first sliding groove 211 is provided with a first locking interface 2111. The first extension arm 412 can extend into the locking interface 2111, thereby realizing the connection between the first extension arm 412 and the keycap 2.
[0053] In some embodiments, the first sliding groove 211 may include a first inlet / outlet 2112. The first inlet / outlet 2112 may be located on the side of the first card interface 2111 near the panel 1. The first inlet / outlet 2112 may be connected to the first card interface 2111. One end of the first extension arm 412 may extend into and engage with the first card interface 2111 through the first inlet / outlet 2112, thereby achieving the connection between the first extension arm 412 and the keycap 2. The opening of the first inlet / outlet 2112 may be slightly smaller than the first extension arm 412, so that when the first extension arm 412 is installed, the first extension arm 412 can squeeze and open the first inlet / outlet 2112, thereby extending into and engaging with the first card interface 2111 through the first inlet / outlet 2112.
[0054] In some embodiments, the bottom surface of the keycap 2 is provided with two spaced-apart second sliding seats 22. The two second sliding seats 22 can be respectively provided on both sides of the elastic key 3. The bottom surface of the second sliding seat 22 is provided with an upwardly extending second sliding groove 221. The second sliding groove 221 can be provided above the panel 1. A second locking interface 2211 is provided on the second sliding groove 221. The second extension arm 422 can extend into the locking interface 2211 to realize the connection between the second extension arm 422 and the keycap 2. The opening of the second inlet / outlet 2212 can be slightly smaller than the second extension arm 422, so that when the second extension arm 422 is installed, the second extension arm 422 can squeeze and open the second inlet / outlet 2212, and then extend into the locking interface 2211.
[0055] In some embodiments, the second sliding groove 221 further includes a second inlet / outlet 2212. The second inlet / outlet 2212 may be located on the side of the second card interface 2211 near the panel 1. The second inlet / outlet 2212 may be connected to the second card interface 2211. One end of the second extension arm 422 may extend into and engage with the second card interface 2211 through the second inlet / outlet 2212, thereby realizing the connection between the second extension arm 422 and the keycap 2.
[0056] Please see Figure 5 and Figure 6 As shown, in some embodiments, the first sliding seat 21 and the second sliding seat 22 located on the same side of the elastic button 3 can be connected. The first sliding groove 211 and the second sliding groove 221 located on the same side of the elastic button 3 can be arranged adjacent to each other at intervals. The first sliding groove 211 can be located on the side of the second sliding groove 221 away from the elastic button 3. Alternatively, the first sliding groove 211 can be located on the side of the second sliding groove 221 closer to the elastic button 3.
[0057] Please see Figure 5 and Figure 6 As shown, in some embodiments, a first guide slope 23 may be provided on the bottom inner wall of the first inlet / outlet 2112. The first extension arm 412 can enter the first inlet / outlet 2112 along the first guide slope 23. The opening at the first guide slope 23 may be larger than the opening of the first inlet / outlet 2112. Thus, when the first extension arm 412 needs to be installed into the first card interface 2111, the first guide slope 23 can guide the installation of the first extension arm 412, allowing the first extension arm 412 to be inserted and engaged into the first card interface 2111 more smoothly and effortlessly.
[0058] In some embodiments, a second guide slope 24 may be provided on the inner wall of the bottom end of the second inlet / outlet 2212. The second extension arm 422 can enter the second inlet / outlet 2212 along the second guide slope 24. The opening at the second guide slope 24 may be larger than the opening of the second inlet / outlet 2212. Thus, when the second extension arm 422 needs to be installed into the second card interface 2211, the second guide slope 24 can guide the installation of the second extension arm 422, allowing the second extension arm 422 to be inserted and engaged into the second card interface 2211 more smoothly and effortlessly.
[0059] In some embodiments, the bottom inner wall of the first card interface 2111 may be provided with a third guide slope 25. The opening of the third guide slope 25 is larger than the opening of the first inlet / outlet 2112. When the first extension arm 412 is inserted and engaged in the first card interface 2111, the first extension arm 412 can be removed from the first inlet / outlet 2112 along the third guide slope 25. Thus, the third guide slope 25 can guide the disassembly of the first extension arm 412, allowing the first extension arm 412 to be removed from the first card interface 2111 more smoothly and effortlessly.
[0060] In some embodiments, the bottom inner wall of the second card interface 2211 may be provided with a fourth guide slope 26. The opening of the fourth guide slope 26 is larger than the opening of the second inlet / outlet 2212. When the second extension arm 422 is inserted and engaged in the second card interface 2211, the second extension arm 422 can be removed from the second inlet / outlet 2212 along the fourth guide slope 26. Thus, the fourth guide slope 26 can guide the disassembly of the second extension arm 422, allowing the second extension arm 422 to be removed from the second card interface 2211 more smoothly and effortlessly.
[0061] In some embodiments, when the keycap 2 is pressed, the first extension arm 412 can abut against the top wall of the first card interface 2111, and the second extension arm 422 can abut against the top wall of the second card interface 2211. Thus, the first extension arm 412 is pressed down by the top wall of the first card interface 2111, and the second extension arm 422 is pressed down by the top wall of the second card interface 2211. The upper and lower ends of the first card interface 2111 and the second card interface 2211 can be at the same height, so that the first extension arm 412 and the second extension arm 422 can descend synchronously. When the keycap 2 is released, the elastic button 3 can push the key to move away from the panel 1. The first extension arm 412 can abut against the bottom wall of the first card interface 2111, and the second extension arm 422 can abut against the bottom wall of the second card interface 2211. The bottom wall of the first card interface 2111 drives the first extension arm 412 upward, and the top wall of the second card interface 2211 presses the second extension arm 422 downward. The bottom walls of the first card interface 2111 and the second card interface 2211 can be at the same height. The first card interface 2111 and the second card interface 2211 can synchronously drive the first extension arm 412 and the second extension arm 422 to rise. When the elastic button 3 rebounds, the two balance bars 4 can make the keycap 2 evenly stressed, so that the keycap 2 moves smoothly and avoids shaking or jamming, thereby improving the user experience.
[0062] Please see Figures 4 to 6 As shown, in some embodiments, a latch 27 is provided on the bottom surface of the keycap 2 extending towards the panel 1. A mounting position 14 corresponding to the latch 27 may be provided on the panel 1. The mounting position 14 can be a snap-fit hole. When the keycap 2 is mounted on the panel 1, the latch 27 on the keycap 2 can extend into and snap into the mounting position 14, thereby improving the stability of the connection between the keycap 2 and the panel 1.
[0063] In some embodiments, two latches 27 may be provided. The two latches 27 may be respectively provided on opposite sides of the keycap 2. Two mounting positions 14 are provided. The two mounting positions 14 may correspond to the two latches 27. When the keycap 2 is mounted on the panel 1, the two latches 27 on the keycap 2 can simultaneously extend into and engage with the two mounting positions 14, thereby further improving the stability of the connection between the keycap 2 and the panel 1.
[0064] It should be noted that in some other embodiments, the latch 27 may be provided in three or more forms.
[0065] Please refer to the figure. In some embodiments, a guide post 28 extends downward from the bottom surface of the keycap 2. A guide groove 15 is provided on the panel 1, which is arranged opposite to the guide post 28. When the keycap 2 is pressed, the keycap 2 moves downward toward the panel 1, and the guide post 28 can slide within the guide groove 15, thereby improving the stability of the keycap 2 during movement.
[0066] In some embodiments, multiple guide posts 28 may be provided. These guide posts 28 may be spaced apart on the bottom surface of the keycap 2. Multiple guide grooves 15 may be provided. Each guide groove 15 may correspond one-to-one with a single guide post 28. When the keycap 2 is pressed, it moves downwards toward the panel 1, and the multiple guide posts 28 can simultaneously slide and be limited within the multiple guide grooves 15, thereby further improving the stability of the keycap 2 during movement.
[0067] In some embodiments, a guide rib 281 may be provided on the outer surface of the guide post 28. The extending direction of the guide rib 281 may be the same as the extending direction of the guide post 28. The guide rib 281 may be arranged to extend vertically. When the keycap 2 is pressed, the keycap 2 moves downward toward the panel 1, and the guide rib 281 can move downward along the guide groove 15, thereby further improving the stability of the keycap 2 during movement.

[0069] Please see Figures 1 to 10 As shown, in some embodiments, the first main body 411 is rotatably disposed on the panel 1. The first extension arm 412 is connected to the keycap 2. There is an angle between the first extension arm 412 and the plane on which the panel 1 is located.
[0070] In some embodiments, the angle between the first extension arm 412 and the plane containing the panel 1 can be 30 degrees. It should be noted that the angle between the first extension arm 412 and the plane containing the panel 1 can also be 45 degrees or 60 degrees, and there is no limitation here.
[0071] In some embodiments, the second main body 421 is rotatably disposed on the panel 1. The second extension arm 422 is connected to the keycap 2. There is an angle between the second extension arm 422 and the plane on which the panel 1 is located.
[0072] In some embodiments, the angle between the second extension arm 422 and the plane containing the panel 1 can be 30 degrees. It should be noted that the angle between the second extension arm 422 and the plane containing the panel 1 can also be 45 degrees or 60 degrees, and there is no limitation here.
[0073] In some embodiments, when it is necessary to remove the keycap 2, the user can pull the keycap 2 upwards, allowing the first extension arm 412 to be pressed into the first inlet / outlet 2112 along the third guide slope 25, and deforming the first inlet / outlet 2112 so that the first extension arm 412 can exit the first latching interface 2111. The second extension arm 422 can be pressed into the second inlet / outlet 2212 along the fourth guide slope 26, and deforming the second inlet / outlet 2212 so that the second extension arm 422 can exit the second latching interface 2211. This causes the stabilizer bar 4 to separate from the slide seat, thereby separating the keycap 2 from the panel 1. Therefore, by utilizing the structural cooperation between the stabilizer bar 4 and the slide seat of this application, the operation of disassembling and maintaining the keycap 2 can be reduced, improving the efficiency of keycap 2 disassembly and maintenance.
[0074] In some embodiments, when keycap 2 needs to be installed, the buckle 27 on keycap 2 is aligned with the mounting position 14 on panel 1, the guide post 28 and the limiting hole are arranged opposite each other, and then keycap 2 is pressed, so that buckle 27 engages with mounting position 14, guide post 28 extends into limiting hole, and first extension arm 412 can be squeezed and opened along first guide slope 23, and enter first slot interface 2111 along first inlet and outlet 2112; second extension arm 422 can be squeezed and opened along second guide slope 24, and enter second slot interface 2211 along second inlet and outlet 2212, thereby realizing the installation of keycap 2. Thus, by utilizing the structural cooperation between buckle 27 and mounting position 14, and between balance bar 4 and sliding seat in this application, the installation efficiency of keycap 2 can be improved.
[0075] As can be seen from the above technical solution, this utility model has at least the following beneficial effects:
[0076] According to the present invention, a control panel 10 for an ultrasonic device includes a panel 1, keycaps 2, elastic buttons 3, and a balance bar 4. Keycaps 2 are movably mounted on the panel 1, and elastic buttons 3 are mounted on the panel 1 and positioned below keycaps 2. The balance bar 4, located below keycaps 2, includes a first balance bar 41 and a second balance bar 42. The first balance bar 41 includes a first main body 411 and a first extension arm 412, and the second balance bar 42 includes a second main body 421 and a second extension arm 422. The first and second main bodies 411 and 421 are rotatably mounted on the panel 1. The first and second extension arms 412 are respectively connected to keycaps 2. The two first extension arms 412 are symmetrically positioned on either side of the elastic buttons 3, and the two second extension arms 422 are symmetrically positioned on either side of the elastic buttons 3. The two first extension arms 412 and the two second extension arms 422 are staggered symmetrically arranged. The first and second extension arms 412 located on one side of the elastic buttons 3 are arranged crosswise. Therefore, when the elastic button 3 is pressed, the two first extension arms 412 and the two second extension arms 422 can descend synchronously. The two first extension arms 412 and the two second extension arms 422 are respectively located on both sides of the elastic button 3, and the first extension arm 412 and the second extension arm 422 on one side of the elastic button 3 are arranged crosswise. This allows the user to trigger the button function by pressing the keycap 2 at any position. At the same time, when the elastic button 3 rebounds, the two balance bars 4 can make the keycap 2 move smoothly, thereby improving the user experience.
