Detailed Implementation

[0035] 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.

[0036] In the description of the utility model, it is understood that in the embodiment shown in the drawings, the indication of direction or position relation (such as up, down, left, right, front and back) is only for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. When these elements are in the position shown in the drawings, these descriptions are appropriate. If the position of these elements changes, the indication of direction also changes accordingly.

[0037] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

[0038] In the prior art, in order to meet the demand of light and thin key assembly, the most commonly used scheme in the combination of standard encoder and key is: selecting a super-thin and hollow encoder, and setting a light touch switch key in the middle of the encoder, so as to meet the control demand of the key assembly.

[0039] However, the space in the super-thin encoder is small, so that after installing the switch key in the middle position, there is no extra space for installing light source, and the key cap character cannot be realized. For example, when the LED lamp is arranged under the hollow encoder and the switch key, due to the small space, the commonly used brightness LED lamp cannot be arranged, only the low brightness flat LED lamp can be selected, the light intensity of the flat LED lamp is insufficient, thereby affecting the brightness of the character. In addition, the hollow light transmission gap of the encoder is small, and the key trigger rod in the middle affects the light propagation, so that the middle dark area of the key cap is obvious, and the light transmission of the character is uneven. Therefore, the character light transmission function of the switch key is cancelled in part of the scheme, thereby affecting the use experience of the operator.

[0040] Therefore, a key assembly for ultrasonic equipment is proposed to solve the above problems.

[0041] The scheme is further illustrated by the following embodiments:

[0042] Figure 1 It is a partial view of the control panel of the utility model embodiment. Figure 2 It is Figure 1 The schematic view of the key assembly of the ultrasonic equipment. Figure 3 It is Figure 2 The sectional view schematic view of the key assembly.

[0043] The ultrasonic device of the embodiment can be used for clinical detection and medical diagnosis, and the ultrasonic device can be arranged as a desktop ultrasonic device or a portable ultrasonic device.

[0045] In addition, the ultrasonic device can further include a display screen. The display screen is electrically connected to the main machine for displaying image information. Specifically, the display screen can be directly arranged on the main machine, such as a portable ultrasonic device. Of course, the display screen can also be arranged separately and electrically connected to the main machine.

[0046] Please refer to Figure 1 The control panel 2 of the embodiment can include a main body 1 and a key assembly 3. The control panel 2 can be connected to the main machine of the ultrasonic device and electrically connected to the main machine, so that the operator can control the operation of the main machine through the control panel 2.

[0047] At the same time, the key assembly 3 is installed on the main body 1, so that the operator can input control signals to the control panel 2 through the key assembly 3, and then the control panel 2 controls the operation of the ultrasonic device.

[0048] In the embodiment, the control panel 2 can further include a touch screen 4. The touch screen 4 is installed on the main body 1 for the operator to input control signals through touch input, and then the control panel 2 controls the operation of the ultrasonic device.

[0049] Please refer to Figure 2 and Figure 3 The key assembly 3 can include a substrate 10, an adapter plate 20, a rotating switch 30 and a key 40.

[0050] The substrate 10 is provided with a receiving hole 11 which is through. It should be noted that the substrate 10 can be arranged as a key PCB of the key assembly 3, or as a PCB of the control panel 2.

[0051] The adapter plate 20 is connected to the substrate 10 and located on one side of the receiving hole 11 in the axial direction. The adapter plate 20 is provided with a key switch 21 and a light source 22 on the side facing the substrate 10, and the key switch 21 and the light source 22 can be accommodated in the receiving hole 11. It should be noted that the key switch 21 and the light source 22 are arranged on the adapter plate 20, which can facilitate the maintenance of the key switch 21 and the light source 22.

[0052] The rotation switch 30 is connected to the base plate 10 and located on the side of the base plate 10 opposite to the adapter plate 20. The rotation switch 30 is provided with a through communication hole 31, and the communication hole 31 is in communication with the accommodation hole 11, that is, the rotation switch 30 and the adapter plate 20 are respectively arranged at two outlets of the accommodation hole 11.

[0053] It should be noted that since the rotation switch 30 is connected at the opening of the accommodation hole 11, and the accommodation hole 11 is in communication with the communication hole 31, there is enough space between the rotation switch 30 and the base plate 10 to place the key switch 21 and the light source 22, so that the light source 22 can use a light source with a larger power, thereby ensuring that the light intensity and brightness of the light source 22 meet the requirements. That is, the light source 22 can use a normal size lamp bead to ensure that the light emission of the light source 22 meets the actual demand.

[0054] At the same time, the key 40 is accommodated in the accommodation hole 11 and the communication hole 31 and can move relative to the adapter plate 20, so that the key 40 can be used to abut and control the opening or closing of the key switch 21.

[0055] Specifically, the key 40 is provided with a first end portion 41 and a second end portion 42 at both ends in the axial direction. The first end portion 41 is located in the accommodation hole 11 and faces the key switch 21. The first end portion 41 can abut the key switch 21, and when the key 40 moves towards the key switch 21, the first end portion 41 can abut the key switch 21 to open the key switch 21. At the same time, the second end portion 42 is located in the communication hole 31, so that the operator can rotate the switch 30 by pressing the second end portion 42 to drive the key 40 to move towards the key switch 21, so that the first end portion 41 abuts the key switch 21 and opens the key switch 21.

[0056] It should be noted that the key switch 21 is provided with a reset structure, so when the operator presses the key 40 to make the key 40 abut the key switch 21, the key 40 needs to overcome the restoring force of the key switch 21 to continue pressing the key switch 21, so that the key switch 21 is opened. When the operator withdraws the pressing force, the reset structure of the key switch 21 can drive the key 40 and the key switch 21 to reset, thereby closing the key switch 21.

[0057] In this embodiment, the second end portion 42 can be provided with characters to facilitate the operator to identify the function of the key. At the same time, the key 40 can be provided as a light-transmitting piece, so that the key 40 can be used to guide the light emitted by the light source 22, and the light is emitted outward from the second end portion 42 and illuminates the characters located at the second end portion 42, thereby improving the user experience.

[0058] It should be noted that the key switch 21 and the rotating switch 30 control different functions respectively, so as to facilitate the operator to control the ultrasonic equipment.

[0059] Specifically, the key assembly 3 can be an echocardiogram imaging key. The operator can control the entering or exiting of the echocardiogram imaging mode by pressing the echocardiogram imaging key, and the operator can adjust the gain of the echocardiogram imaging mode by rotating the echocardiogram imaging key, so as to facilitate the electrocardiogram display.

[0060] Meanwhile, the key assembly 3 can be a pulse Doppler imaging key. The operator can control the entering or exiting of the pulse Doppler imaging mode by pressing the pulse Doppler imaging key, and the operator can adjust the gain of the pulse Doppler imaging mode by rotating the pulse Doppler imaging key, so as to facilitate the Doppler imaging display.

[0061] Furthermore, the key assembly 3 can be a color Doppler imaging key. The operator can control the entering or exiting of the color Doppler imaging mode by pressing the color Doppler imaging key, and the operator can adjust the gain of the color Doppler imaging mode by rotating the color Doppler imaging key, so as to facilitate the color Doppler imaging display.

[0062] In addition, the key assembly 3 can be a brightness imaging key. The operator can control the entering or exiting of the brightness imaging mode by pressing the brightness imaging key, and the operator can adjust the gain of the brightness imaging mode by rotating the brightness imaging key, so as to adjust the brightness of the imaging.

[0063] Figure 4 is Figure 2 a simplified schematic view of the adapter plate of the key assembly. Figure 5 is Figure 2 a simplified schematic view of the connection of the adapter plate and the substrate of the key assembly.

[0064] Referring to Figure 4 and Figure 5 , the adapter plate 20 can be provided with a plurality of connection pins 23, which are arranged at intervals along the opposite sides of the adapter plate 20. The connection pins 23 are used to electrically connect the substrate 10 and fixedly connect the adapter plate 20 to the substrate 10.

[0065] It should be noted that the distance between the adjacent connection pins 23 on the same side of the adapter plate 20 is greater than or less than the distance between the adjacent connection pins 23 on the opposite side of the adapter plate 20, that is, the distance between the two adjacent connection pins 23 on the same side of the adapter plate 20 is different from the distance between the two adjacent connection pins 23 on the other side, so as to prevent mistakes, avoid the welding error of the connection pins when the adapter plate 20 is welded to the substrate 10, and ensure that the adapter plate 20 can be accurately connected to the substrate 10.

[0066] In the embodiment, the adapter plate 20 is provided with eight connecting pins 23 for connecting with the substrate 10. Specifically, as shown in Figure 5 Fig. 2, the pin 2-12V and the pin 3-GND are power supply pins for providing power supply and signals. The pin 1-ROW and the pin 5-LINE are pins for transmitting key signals, and the pin 4-GND is a ground pin for ensuring the safe operation of the adapter plate 20. The pin 6-LED3, the pin 7-LED2 and the pin 8-LED1 are control signal pins of the light source 22 for controlling the light-emitting state of the light source 22.

[0067] In addition, the adapter plate 20 can also be provided with fixing pads 24. The fixing pads 24 are provided in four and are distributed at intervals on the adapter plate 20. Specifically, the fixing pads 24 are used to weld the adapter plate 20 on the substrate 10 to ensure that the adapter plate 20 is stably connected with the substrate 10, avoiding the adapter plate 20 from being separated from the substrate 10 when the user presses the key 40 with too much pressing force.

[0068] It should be noted that the fixing pads 24 are provided in four and are distributed at intervals on the adapter plate 20 and are welded with the substrate 10. As shown in Figure 5 Fig. 2, the four fixing pads 24 are PAD1, PAD2, PAD3 and PAD4 respectively.

[0069] Referring to Figure 4 Fig. 3, the light source 22 can include a plurality of LED lamps 221. The plurality of LED lamps 221 are distributed at intervals around the periphery of the key switch 21, so that the plurality of LED lamps 221 can be accommodated in the accommodating hole 11. And the plurality of LED lamps 221 surround the key switch 21, so that the light emitted by the plurality of LED lamps 221 can propagate along the key 40 and diverge outwardly from the second end portion 42.

[0070] At the same time, the LED lamp 221 can be controlled and emit light of different colors and different brightness. Specifically, the LED lamp 221 can be provided as a single-color, double-color or triple-color LED lamp body, and different LED lamp bodies can be selected between different LED lamps 221, so that the light source 22 can emit light of different colors. In addition, different LED lamps 221 can be controlled to emit light of different intensities, so that the color and illumination intensity of the light source 22 meet the needs of different operators.

[0071] In the embodiment, the light source 22 is provided with four LED lamps 221, and the four LED lamps 221 are connected in series to reduce power consumption. Of course, in some other embodiments, the four LED lamps 221 can also be connected in parallel, so that the four LED lamps 221 can emit light.

[0072] In addition, the color or brightness of the four LED lamps 221 is controlled by using 8-bit PWM control, so that the LED lamp can emit 2 8 kinds of brightness, i.e. 256 kinds of brightness. At the same time, the LED lamp 221 of the present application uses RGB three-color lamp, and by adjusting the duty cycle of PWM, different colors can be adjusted, and up to 256*256*256=16777216 colors can be realized, so as to enrich the light color of the light source 22 and meet the use requirements of different operators.

[0076] Referring to Figure 2 , Figure 6 , Figure 7 and Figure 8 , the key assembly 3 can further include a rotating cap 50.

[0077] Specifically, the rotating cap 50 is connected to the outer circumferential side of the rotating switch 30 for controlling the rotating switch 30. Specifically, the rotating cap 50 is connected to the rotating part 35, so that when the operator rotates or adjusts the rotating cap 50, the rotating cap 50 can drive the rotating part 35, and thus the rotating switch 30 can control different functions.

[0078] At the same time, the rotating cap 50 is provided with a through sleeve channel 51, and the sleeve channel 51 is used for penetrating the key 40. Specifically, the inner wall of the sleeve channel 51 is connected to the rotating part 35, so that the rotating cap 50 can drive the rotating part 35 to rotate, so that the key 40 can be penetrated in the sleeve channel 51 and extend out of the sleeve channel 51, facilitating the operator to operate the key 40.

[0079] Referring to Figure 6 and Figure 8The side wall of the sleeving channel 51 can be provided with a clamping portion 52, and the rotating end of the rotating switch 30 is provided with a connecting portion 32, that is, the connecting portion 32 is arranged on the rotating portion 35. At the same time, the connecting portion 32 is arranged corresponding to the clamping portion 52, so that the clamping portion 52 is clamped on the connecting portion 32, so that the rotating cap 50 is limited on the rotating switch 30 in the axial direction, avoiding the rotating cap 50 from separating from the rotating switch 30 in the axial direction.

[0080] In addition, the side wall of the sleeving channel 51 is further provided with a limiting protrusion 53, and the rotating end of the rotating switch 30 is provided with a limiting groove 33, that is, the limiting groove 33 is arranged on the rotating portion 35.

[0081] In the embodiment, the key assembly 3 can further include a light-reflecting film. The light-reflecting film is attached to the side wall of the sleeving channel 51, so as to reflect the light emitted by the light source 22, so that the light can be aggregated and emitted from the outlet of the sleeving channel 51, thereby enabling the light to illuminate the second end portion 42 of the key 40.

[0082] It should be noted that the light-reflecting film can also be arranged on the end portion of the rotating portion 35 away from the body 34, so that the light-reflecting film can reflect the light and make the light emitted from the opening of the sleeving channel 51.

[0085] Referring to Figure 9 and Figure 10 , the first end portion 41 is further provided with a flange portion 412. The flange portion 412 is arranged on the outer circumferential side of the first end portion 41.

[0086] In the embodiment, when the key 40 is arranged in the through hole 31 and the accommodating hole 11, the flange portion 412 is located between the adapter plate 20 and the end portion of the rotary switch 30, that is, the flange portion 412 is accommodated in the accommodating hole 11, so that the adapter plate 20 and the end portion of the rotary switch 30 are respectively located on both sides of the flange portion 412 in the axial direction and limit the flange portion 412, thereby limiting the key 40 in the accommodating hole 11 and the through hole 31, and avoiding that the key 40 is separated from the accommodating hole 11 and the through hole 31 in the axial direction.

[0087] It should be noted that the flange portion 412 is connected with the avoiding portion 411, and the avoiding portion 411 is communicated with the avoiding groove 413, and the avoiding groove 413 is partially formed on the flange portion 412, so that the avoiding groove 413 can be used to avoid the light source 22 on the adapter plate 20, and avoid that the first end portion 41 of the key 40 interferes with the light source 22.
