[0052] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0053] When doctors make house calls, they need to check the battery level of their portable equipment first. Existing portable ultrasound devices require the device to be powered on before displaying the remaining battery level, or a separate electronic display screen is needed. The former is inconvenient, and the latter is costly, indicating room for improvement. Therefore, this invention provides a battery level display device for portable ultrasound devices, which can be integrated into the portable ultrasound device or mounted as a separate external device.

[0054] See Figure 10 and Figure 16 This embodiment provides a power display device 100, which is applied in a portable ultrasound device 200. The portable ultrasound device 200 includes at least a battery 300, which is electrically connected directly or indirectly to the power display device 100.

[0055] The portable ultrasound device 200 also includes at least a main unit 500, with a battery 300 housed within the main unit 500. A power display device 100 is integrated into the main unit 500 or connected to the main unit 500 as an external component, and its function is to display the remaining power of the battery 300 within the main unit 500 when the main unit 500 is not powered on.

[0056] In one application scenario, the power display device 100 is pluggably connected to the main unit 500 as an external component. The main unit 500 may have an interface that is directly or indirectly connected to the battery 300. When a doctor needs to make outpatient visits, the power display device 100 can be inserted into multiple portable ultrasound devices 200 in sequence. When the main unit 500 is not powered on, the power display device 100 directly displays the remaining power of the battery 300. The doctor can then select a portable ultrasound device 200 with appropriate power for outpatient visits based on the actual situation.

[0057] In another application scenario, the power display device 100 is directly integrated into the host 500 and exists as part of the host 500. In this case, in addition to displaying the remaining power of the battery 300, the power display device 100 also needs to meet the requirements of aesthetically pleasing and reliable structure, as well as simple installation and maintenance.

[0058] This embodiment uses the example of a power display device 100 integrated within a host 500. See also... Figure 10 The portable ultrasound device 200 in this embodiment includes a main unit 500, a flip cover 600 that is rotatably connected to the main unit 500, and a handle 700 provided on the main unit 500 for easy carrying by the user. The power display device 100 can be integrated into any one of the main unit 500, the flip cover 600, or the handle 700. In this embodiment, the power display device 100 is integrated into the main unit 500 as an example. Most of the power display device 100 can be hidden inside the main unit 500, but at least the part that displays the remaining power is exposed on the main unit 500.

[0059] It is understood that the structure of the portable ultrasound device 200 is not limited to the combination of the main unit 500, the flip cover 600, and the handle 700. For example, the handle 700 may be omitted, or other functional structures may be included. Correspondingly, the power display device 100 may be integrated into any of the main unit 500 or other functional structures, or the main components of the power display device 100 may be distributed among the main unit 500 or other functional structures. For example, the power display device 100 may include at least a part for displaying the power level and a part for triggering the power level display, see [reference needed]. Figure 18 The part used to display the battery level is indicated by the battery icon 11, and the part used to trigger the battery level display is indicated by the infrared light-transmitting area 12. The part used to display the battery level is located on the side of the handle 700, while the part used to trigger the battery level display is located in the center of the handle 700. For example, see... Figure 19 The part used to display the battery level is still referred to by the battery icon 11, and the part used to trigger the battery level display device is still referred to by the infrared light-transmitting area 12. The part used to display the battery level is located on the main unit 500, while the part used to trigger the battery level display is located on the handle 700.

[0060] Accordingly, when the portable ultrasound device 200 includes any combination of the main unit 500, flip cover 600, handle 700 or other structures, the position of the power display device 100 exposed among the above-mentioned components can be any one of them, or, as needed, it can be exposed at any position among the above-mentioned components simultaneously.

[0061] exist Figures 1-2 Based on this, see Figure 5 and Figure 17 The power display device 100 includes at least: a cover plate 10 and a lamp body device 20.

[0062] The lamp body device 20 is used to display the remaining power of the battery 300. In this embodiment, the lamp body device 20 is hidden inside the main unit 500, and the current battery power of the battery 300 is displayed to the user through the cover 10. It is understood that the lamp body device 20 can also be hidden in the handle 700 or the flip cover 600. The following focuses on the example of the lamp body device 20 being set inside the main unit 500, without going into too much detail.

[0063] The cover plate 10 is also considered as part of the power display device 100 that is exposed on the main unit 500 for displaying power level. It can be a separate component assembled with the lamp body device 20, or it can be integrally formed on the main unit 500, or assembled on the main unit 500 and cooperate with the lamp body device 20. Its function is to protect the lamp body device 20 and improve its visual display effect.

[0064] In this embodiment, see Figure 2 The cover plate 10 is a long strip-shaped structure, and its length, width, and thickness are not limited. See also Figure 1 The cover plate 10 is silkscreened with a battery icon 11, and the position of the battery icon 11 corresponds to the position of the lamp body device 20.

[0065] See Figure 3 , Figure 7 , Figure 8 and Figure 10 In this embodiment, the host 500 includes: a panel housing 400, and a cover plate 10 assembled on the panel housing 400. Figure 2 The lamp body device 20 is hidden below the battery icon 11 on the cover plate 10. Figure 3In the assembly diagram, the lamp body device 20 is not directly exposed on the host 500, but after the light source 21 in the lamp body device 20 is lit, the light can pass through the battery icon 11 on the cover 10 and be perceived by the user.

[0066] In this embodiment, at least a portion of the cover plate 10 corresponding to the lamp body device 20 is made of transparent or semi-transparent material. The portion made of transparent or semi-transparent material is designated as the light-transmitting area 111, so that the lamp body device 20 can be observed by the user through the light-transmitting area 111 of the battery icon 11, at least when it is lit, thereby displaying the remaining power of the battery 300.

[0067] Optionally, the battery icon 11 on the cover plate 10, corresponding to the position of the lamp body device 20, also includes a non-transparent area 112. The non-transparent area 112, the transparent area 111, and other areas of the cover plate 10 can be set to the same color scheme. Further, the non-transparent area 112 and other areas of the cover plate 10 can be set to the same color. In this embodiment, the transparent area 111 of the battery icon 11 is black and semi-transparent. The non-transparent area 112 and other areas of the cover plate 10 are the same color and are all black.

[0068] exist Figure 1 Based on, and refer to Figure 5 , Figure 9 and Figure 17 Preferably, the lamp body device 20 may include a plurality of light sources 21, which are arranged in the shape of a battery 300. The shape of the battery 300 may include only a symbol or shape for indicating the battery's charge level, or it may include other symbols or shapes that surround, intersect, tangent to, overlap with, are adjacent to, or are discrete around the shape or symbol. In this embodiment, see [reference needed]. Figure 1 The battery icon 11 has the following shape: an outer outline of approximately a large rectangle enclosing multiple small rectangular structures arranged side by side. See also... Figure 9 Multiple light sources 21 form a shape that conforms to the shape of the battery icon 11.

[0069] Specifically, at least a portion of the plurality of light sources 21 are used to combine and form the shape of the outer contour of an approximate large rectangle representing the battery icon 11. This portion of the light sources 21 is referred to as the first light source 211. In this embodiment, see [link to documentation]. Figure 1 The outer outline of battery icon 11 is approximately rectangular. (See also...) Figure 9 Multiple primary light sources 211 are arranged end-to-end in an approximately rectangular queue. See also... Figure 9 and Figure 1 When the first light source 211 is lit, the light passes through the cover plate 10 and illuminates the outer outline of the battery icon 11 on the cover plate 10, so that the user can clearly see the outer outline of the battery icon 11.

[0070] At least another portion of the plurality of light sources 21 is used to combine and form a symbol or shape representing the remaining power of the battery 300. This portion of the light source 21 used to represent the remaining power of the battery 300 is denoted as the second light source 212. In this embodiment, see [reference needed]. Figure 9 These second light sources 212 are arranged side by side. The number of lit light sources 21 indicates the current remaining power of the battery 300. The more lit light sources 21, the more power the battery 300 has remaining, and vice versa.

[0071] For example, the lamp body device 20 also includes a light shield 22 and a first circuit board 24. The light shield 22 is disposed on the first circuit board 24 and located on the side of the first circuit board 24 near the cover plate 10. The first circuit board 24 is electrically connected directly or indirectly to the battery 300. The light source 21 is integrated on the first circuit board 24 and is surrounded within the light shield 22. The light shield 22 serves to protect the light source 21 and also to separate different groups of light sources 21 to guide the direction of the light from the light source 21 and prevent cross-contamination between different groups of light sources 21. In this embodiment, since the light source 21 includes at least a first light source 211 and a second light source 212, the light shield 22 also separates at least the first light source 211 and the second light source 212 to prevent cross-contamination between the first light source 211 and the second light source 212.

[0072] Furthermore, the light-shielding frame 22 needs to be compatible with the structure of the main unit 500 to achieve simple installation and maintenance. In this embodiment, the main unit 500 includes a panel shell 400, and the light-shielding frame 22 includes an outer frame 221 and an inner frame 222, see [reference needed]. Figure 17 The height H1 of the outer frame is lower than the height H2 of the inner frame. For ease of installation, disassembly, and maintenance of the power display device 100, please refer to... Figure 6 The cover plate 10 overlaps the upper part of the inner frame 222, and the outer frame 221 is pressed down by the panel shell 400.

[0073] During maintenance, the light source 21 can be maintained without removing the lamp body assembly 20 by removing the cover plate 10. If it is necessary to completely remove the lamp body assembly 20, the panel shell 400 can be further removed. During installation, installing the panel shell 400 can effectively fix the lamp body assembly 20, and further installing the cover plate 10 can prevent the lamp body assembly 20 from being directly exposed to the outside. This greatly simplifies the installation and maintenance steps.

[0074] See Figure 1 , Figure 5 and Figure 9 The light-shielding frame 22 also includes: spacer strips 223. Multiple spacer strips 223 are integrally formed inside the inner frame 222 and have the same height as the inner frame 222.

[0075] Specifically, the light-shielding frame 22 forms multiple light-transmitting gaps 23 through the inner frame 222, the outer frame 221, and multiple spacers 223. The area enclosed between the inner frame 222 and the outer frame 221 is referred to as the first gap 231, and the area inside the inner frame 222 that is separated by multiple spacers 223 is referred to as multiple second gaps 232.

[0076] A first light source 211 for illuminating the outer contour of the battery icon 11 is disposed within the first gap 231. In this embodiment, the first light source 211 may be an LED light. See [link to relevant documentation]. Figure 1 and Figure 9 Both the inner frame 222 and the outer frame 221 are approximately rectangular battery-shaped structures, and the first gap 231 formed by them is also approximately battery-shaped. Multiple first light sources 211 are symmetrically distributed within the first gap 231. Specifically, in... Figure 9 From the viewing angle, four LEDs are symmetrically distributed on the top and bottom sides, and two LEDs are symmetrically distributed on the left and right sides, to illuminate the outer contour of the battery icon 11.

[0077] A second light source 212, used to illuminate a symbol or shape representing the battery capacity 300, is disposed within the second gap 232. In this embodiment, the second light source 212 is also an LED light, and multiple spacers 223 divide the area enclosed by the inner frame 222 into multiple second gaps 232. In this embodiment, the second light source 212 consists of multiple LED lights arranged side by side, with each LED light correspondingly disposed within one second gap 232. In this embodiment, there are 5 second light sources 212. Correspondingly, there are 4 spacers 223 to divide the inner frame 222 into 5 second gaps 232, with each of the 5 LED lights disposed within one of the 5 second gaps 232. Lighting up a corresponding number of LEDs out of 5 LEDs can indicate different remaining battery levels for battery 300. For example, all 5 LEDs lit indicates a remaining battery level of 80% to 100%, 4 LEDs lit indicates a remaining battery level of 60% to 80%, 3 LEDs lit indicates a remaining battery level of 40% to 60%, 2 LEDs lit indicates a remaining battery level of 20% to 40%, 1 LED lit indicates a remaining battery level of 10% to 20%, and 0 LEDs lit indicates a remaining battery level of 0% to 10%.

[0078] It is understood that the light source 21 is not limited to LED lights, and the first light source 211 and the second light source 212 are not limited to the same type of light. Furthermore, the multiple light sources 21 in the first light source 211 and the second light source 212 are not limited to the same type of light. The light source 21 can be one or more of different types of light, such as OLED lights, fluorescent lights, miniature incandescent lamps, miniature plasma light sources, electroluminescent lamps, or thermal radiation light sources, or a combination thereof.

[0079] Preferably, the multiple light-transmitting gaps 23 formed by the light-shielding frame 22 are directly opposite the light-transmitting area 111. Specifically, see... Figure 3 The light-transmitting area 111 includes: a first light-transmitting area 1111 and a second light-transmitting area 1112. See also... Figure 3 and Figure 5 The first gap 231 faces the first light-transmitting area 1111, and multiple second gaps 232 face multiple second light-transmitting areas 1112. "Facing each other" can be understood as the projections of the first gap 231 and the first light-transmitting area 1111 onto the cover plate 10 overlap, allowing light emitted from the first light source 211 within the first gap 231 to reach and illuminate the first light-transmitting area 1111, thereby illuminating the outer contour of the battery icon 11. Similarly, for the second gaps 232 and the second light-transmitting areas 1112, each second gap 232 faces a second light-transmitting area 1112. This can be understood as the projections of each second gap 232 and the corresponding second light-transmitting area 1112 onto the cover plate 10 overlap, allowing light emitted from the second light source 212 within each second gap 232 to reach and illuminate the second light-transmitting area 1112.

[0080] Preferably, combined with Figure 5 and Figure 6 As shown, to further improve the visual effect of the power display device 100, the cover plate 10 is provided with a light-diffusing film layer 31 at the battery icon 11. The function of the light-diffusing film layer 31 is to uniformly distribute the light emitted by the light source 21, avoiding concentrated or uneven distribution of light, thereby ensuring a smooth and clear display of the remaining power of the battery 300. The uniform film layer can be one or more of the following: a transparent plastic film layer, a microlens film layer, an optical coating, an optical fiber film layer, a dot matrix diffusion film layer, and a liquid crystal light-diffusing film layer. In this embodiment, the light-diffusing film layer 31 is an optical coating, specifically a light-diffusing varnish layer. The light-diffusing film layer 31 can be provided on the side of the cover plate 10 facing the first circuit board 24 (i.e., facing the lamp body device 20), or it can be provided on the side of the cover plate 10 facing away from the first circuit board 24. In this embodiment, the light-diffusing film layer 31 can be sprayed on the side of the cover plate 10 facing the lamp body device 20.

[0081] Optionally, the power display device 100 further includes a diffusion film 32, which is disposed between the cover plate 10 and the light shield 22. In this embodiment, the diffusion film 32 is disposed on the side of the light-diffusing film layer 31 facing away from the cover plate 10. Specifically, see... Figure 6 The upper part of the diffusion film 32 is attached to the light-diffusing film layer 31, and the lower part of the diffusion film 32 abuts against the top of the inner frame 222 and the panel shell 400.

[0082] Specifically, the diffusion film 32 is a material commonly used in optical systems. Its function is to uniformly diffuse the light emitted by the light source 21, making the light distribution more even within the display or illumination area, avoiding excessively strong light spots or shadows, and effectively improving the uniformity and clarity of the display effect. The diffusion film 32 can be one or more of the following: a microparticle diffusion film, a double-sided frosted film, a microstructure diffusion film, an optical-grade coated diffusion film, or an optical diffusion fiber film. In this embodiment, the diffusion film 32 is an optical diffusion fiber film.

[0083] Optionally, see Figure 1 and Figure 5 The power display device 100 also includes a start device 40, which is electrically connected to the lamp body device 20 and is used to control the lamp body device 20 to turn on. In this embodiment, the objects controlled by the start device 40 include at least a first light source 211 and a second light source 212. The first light source 211 is used to illuminate the outer contour of the battery icon 11. When the start device 40 sends a start signal, the first light source 211 lights up and remains lit for at least a period of time. For example, after lighting up the 16 LEDs of the first light source 211, it remains lit for 1 minute and then turns off. It is understood that the control rules of the light source 21 can be flexibly controlled according to the actual situation and are not limited to the two examples mentioned above.

[0084] The type of activation device 40 is not limited; it can be user-triggered or passively triggered based on environment or conditions. For example, it can be triggered by a button, touch, gesture, voice control, or remote app command. It can also be triggered based on environmental conditions such as light intensity, sound intensity, or vibration intensity. A typical example is when a doctor picks up the device from sleep mode or begins operation, the accelerometer senses the device's movement and automatically triggers the battery display. Another example is in environments like hospitals where lighting conditions may change significantly; a photosensor can trigger the battery display when the device moves from a dark environment to a bright one. Yet another example is when a doctor triggers the activation device 40 by touching a specific area on the device; the touch sensor can automatically activate the battery display 100 upon touch.

[0085] In this embodiment, the activation device 40 is a sensing device. Specifically, the activation device 40 can use an infrared type gesture sensor 41 as the core component of the sensing device. The sensing device is located below the cover plate 10 and emits infrared light upwards. When the doctor performs a specific gesture in the infrared light irradiation area, the gesture sensor 41 detects the infrared light reflected by the doctor's hand, thereby sensing the presence of the hand and outputting an activation signal to light up the light source 21 to display the remaining power of the battery 300.

[0086] See also Figure 1 , Figure 4 and Figure 9 The sensing device includes a gesture sensor 41, a second circuit board 42, and a sleeve 43. The gesture sensor 41 and the sleeve 43 are disposed on the second circuit board 42, and the sleeve 43 is supported between the cover plate 10 and the second circuit board 42. The gesture sensor 41 is located inside the sleeve 43 and is electrically connected to the second circuit board 42. The second circuit board 42 is electrically connected to the first circuit board 24 of the lamp body device 20 to control the activation of the light source 21 on the first circuit board 24.

[0087] The gesture sensor 41 includes an infrared transmitter and an infrared receiver. Infrared light emitted by the infrared transmitter is emitted along the extension direction of the sleeve 43, passes through the cover plate 10, and radiates above the cover plate 10. When the user's hand moves across the area radiated by the infrared light, the infrared light reflected by the hand travels along the sleeve 43 to the infrared receiver, and is converted into a digital signal representing the gesture. The digital signal is sent from the second circuit board 42 to the first circuit board 24 of the lamp body device 20 to activate the first light source 211 and the second light source 212 on the first circuit board 24. The first light source 211 is lit to illuminate the outline of the battery icon 11, and the second light source 212 is lit to display the remaining power of the battery 300.

[0088] The second circuit board 42 can be directly or indirectly electrically connected to the first circuit board 24. In this embodiment, the second circuit board 42 and the first circuit board 24 are electrically connected via a flexible ribbon cable. The connection method between the gesture sensor 41 and the second circuit board 42 is not limited and can be one or more combinations of bus connection, serial port connection, pin connection, or wireless connection. In this embodiment, the gesture sensor 41 is connected to the second circuit board 42 via GPIO pins.

[0089] See also Figure 1 and Figure 5The cover plate 10 may be provided with an infrared light-transmitting area 12 through which infrared light can pass. An infrared type gesture sensor 41, hereinafter referred to as an infrared sensor, faces the infrared light-transmitting area 12. "Facing" can be understood as the infrared light-transmitting area 12 and the projection of the infrared sensor on the cover plate 10 overlap, so that the infrared light emitted by the infrared sensor can pass through the sleeve 43 and radiate above the cover plate 10 through the infrared light-transmitting area 12. In addition, the infrared light reflected back when the user's hand moves across the infrared light radiation area can pass through the infrared light-transmitting area 12 and through the sleeve 43 to reach the infrared sensor.

[0090] Furthermore, the infrared light-transmitting area 12 can be integrally formed on the cover plate 10, or it can be embedded or snapped into the cover plate 10 in other structural combinations. In this embodiment, the infrared light-transmitting area 12 is integrally formed on the cover plate 10, and the infrared light-transmitting area 12 is configured as a semi-transparent black to match the black color scheme of the cover plate 10 and the battery icon 11, thereby improving the overall visual effect. It is understood that the infrared light-transmitting area 12 is not limited to black, nor is it limited to the black color scheme. The infrared light-transmitting area 12, the battery icon 11, and other areas of the cover plate 10 can be configured as the same color scheme or as different color schemes. The light-transmitting area 111 of the infrared light-transmitting area 12 and the battery icon 11 (e.g., Figure 3 The material can be configured to be transparent or translucent, and the transparency can be flexibly configured according to the actual situation. In this embodiment, the transmittance of the infrared light-transmitting area 12 is denoted as P, which satisfies the relationship: 72% < P < 78%. More specifically, the transmittance P = 75%.

[0091] In this embodiment, see also Figure 1 and Figure 5 Both the lamp body assembly 20 and the starting device 40 are located below the cover plate 10. Screw holes are provided on the first circuit board 24 of the lamp body assembly 20 and the second circuit board 42 of the starting device 40. (See also...) Figure 4 and Figure 8 The lamp body assembly 20 and the starting device 40 are connected to the main unit 500 (e.g., via screw holes on the first circuit board 24 and the second circuit board 42) through screw holes. Figure 10 ( ) phase fixed.

[0092] In the above Figure 1 and Figure 5 Based on the combination Figure 10In this embodiment, the host 500 includes an upper panel shell 400 and a lower bottom shell that mates with the panel shell 400. Both the panel shell 400 and the bottom shell are components of the host 500's outer casing, which may also include other shell structures. In this embodiment, the portable ultrasound device 200 inputs data via a keyboard; correspondingly, the panel shell 400 specifically refers to the keyboard panel shell. It can be understood that if the portable ultrasound device 200 interacts with the user via a full touchscreen, the panel shell 400 specifically refers to the touchscreen panel shell. On one hand, the lamp body device 20 and the start device 40 are fixed to the bottom shell via screw holes on the first circuit board 24 and the second circuit board 42; on the other hand, simultaneously... Figure 6 As shown, the keyboard panel housing 400 can press down on the lamp body device 20 or the starter device 40 from top to bottom. The accompanying drawings mainly show the keyboard panel housing 400 positioned above the light shield 22 of the lamp body device 20 and pressing down on the outer frame 221 of the light shield 22. Similarly, the keyboard panel housing 400 can also be configured to press down on the sleeve 43 of the starter device 40 from top to bottom, but this is not shown in the accompanying drawings of this embodiment.

[0093] During installation, first tighten the first circuit board clip 24 and the second circuit board clip 42 to the bottom shell screws, then cover with the keyboard panel shell 400 for further fixation, and finally cover with the diffuser film 32 and the cover plate 10 to complete the assembly. For maintenance, first remove the cover plate 10 and the diffuser film 32 to perform initial maintenance on the starting device 40 and the lamp body device 20. If further maintenance is required, further remove the keyboard panel shell 400 to obtain more maintenance space. If even more thorough maintenance is needed, completely remove the first circuit board clip 24 or the second circuit board clip 42 from the bottom shell for more complete maintenance. Thus, users can perform different levels of maintenance according to their needs, greatly reducing the difficulty of equipment maintenance.

[0094] Further, see Figure 2 and Figure 5 In this embodiment, the keyboard panel housing 400 also includes light-transmitting holes. The light-transmitting holes include a first light-transmitting hole 410 that mates with the lamp housing 20, and a second light-transmitting hole 420 that mates with the activation device 40. The first light-transmitting hole 410 is configured to allow the inner frame 222 of the lamp housing 20 to pass through, while restricting the outer frame 221 from passing through. See also... Figure 5The inner frame 222 passes through the first light-transmitting hole 410 longitudinally. The lateral dimension of the inner contour of the first light-transmitting hole 410 is smaller than the lateral dimension of the outer contour of the outer frame 221, thereby restricting the outer frame 221 from passing through the first light-transmitting hole 410 longitudinally. Specifically, the first light-transmitting hole 410 is also configured such that the projection of the first gap 231 between the outer frame 221 and the inner frame 222 on the panel shell 400 and the projection of the plurality of second gaps 232 within the inner frame 222 on the panel shell 400 are both completely located within the first light-transmitting hole 410.

[0095] The second light-transmitting hole 420 is configured to allow the sleeve 43 of the starting device 40 to pass through, while restricting the passage of the second circuit board card 42. See also Figure 2 and Figure 5 The sleeve 43 passes longitudinally through the second light-transmitting hole 420. The lateral dimension of the inner contour of the second light-transmitting hole 420 is smaller than the lateral dimension of the outer contour of the second circuit board 42, thereby restricting the second circuit board from passing longitudinally through the second light-transmitting hole 420. In this embodiment, the second circuit board 42 is fixed to the bottom shell, and only when the screw comes loose does it prevent the starting device 40 from passing through the second light-transmitting hole 420. For example, during maintenance, if the user removes the cover plate 10 to perform maintenance on the device without further removing the keyboard panel shell 400, the second light-transmitting hole 420 can prevent the starting device 40 from detaching if the screw comes loose.

[0096] Correspondingly, the first light-transmitting hole 410 corresponds to the lamp body device 20, and the lamp body device 20 corresponds to the battery icon 11 on the cover plate 10. Therefore, the first light-transmitting hole 410 also corresponds to the battery icon 11. In this embodiment, the battery icon 11 is located above the first light-transmitting hole 410. The light emitted by the light source 21 of the lamp body device 20 illuminates the battery icon 11 after passing through the first light-transmitting hole 410, the diffusion film 32, the light-diffusing film layer, and the cover plate 10 in sequence.

[0097] Correspondingly, the second light-transmitting hole 420 corresponds to the starting device 40, and the starting device 40 corresponds to the infrared light-transmitting area 12 on the cover plate 10. Furthermore, the second light-transmitting hole 420 corresponds to the infrared light-transmitting area 12. In this embodiment, the infrared light-transmitting area 12 is located above the second light-transmitting hole 420. The infrared light emitted by the starting device 40 is emitted upwards along the sleeve 43, passes through the infrared light-transmitting area 12 of the cover plate 10, and then radiates above the cover plate 10.

[0098] Understandably, the positions of the first light-transmitting hole 410 and the second light-transmitting hole 420 can vary depending on the composition of the portable ultrasound device 200. The positions of the first light-transmitting hole 410 and the second light-transmitting hole 420 on the portable ultrasound device 200 are primarily determined by the positions of the lamp body device 20 and the activation device 40. The lamp body device 20 and the activation device 40 can be arranged adjacent to each other or configured in different positions on the device. The lamp body device 20 and the activation device 40 are not visually directly exposed on the device; the following example, using the position of the battery icon 11 directly exposed on the device, indirectly illustrates the different installation positions of the lamp body device 20 and the activation device 40 on the device.

[0099] For example, see Figure 10 The portable ultrasound device 200 includes a main unit 500, a handle 700, and a flip cover 600. The main unit 500 is larger than the flip cover 600. When the main unit 500 and the flip cover 600 are attached, at least part of the side of the main unit 500 facing the flip cover 600 is exposed. A battery icon 11 is located on the portion of the main unit 500 exposed by the flip cover 600. In the accompanying drawings, the area where at least part of the side of the main unit 500 facing the flip cover 600 is exposed is located between the flip cover 600 and the handle 700. The battery icon 11 is located between the handle 700 and the flip cover 600, and is positioned relatively to the left. It is understood that the area where at least part of the side of the main unit 500 facing the flip cover 600 is exposed can also be located in other positions, and the position of the battery icon 11 in the area is not limited to the left side; it can be in the middle, the right side, or other positions.

[0100] For example, a portable ultrasound device 200 includes a main unit 500, a handle 700, and a flip cover 600. Regardless of whether the size of the main unit 500 is larger than the size of the flip cover 600, and regardless of whether the flip cover 600 is flipped to fit snugly against the main unit 500, there are always multiple exposed areas on the main unit 500, and the battery icon 11 can be located in any of these multiple areas. See also Figure 11 The side of the main unit 500 furthest from the handle 700 (i.e., the area closer to the rear of the main unit 500) is one of the always exposed areas. The battery icon 11 can be placed in this area; understandably, the battery icon 11 can be located anywhere within this area. For example... Figure 15 The battery icon 11 can also be located on the right side of the main unit 500. Naturally, the battery icon 11 can also be located on the left side, front or back of the main unit 500, or other locations that are easy for the user to observe.

[0101] For example, see Figure 12 The portable ultrasound device 200 includes a main unit 500, a handle 700 and a flip cover 600, with a battery icon 11 located on the flip cover 600.

[0102] Accordingly, the thickness of the flip cover 600 needs to be designed to accommodate the start-up device 40 and the lamp body device 20, or the start-up device 40 can be located in another position on the device, with only the lamp body device 20 located on the cover 10 at the position corresponding to the battery icon 11. The start-up device 40 and the lamp body device 20 communicate and control each other via wireless transmission. It is understood that the battery icon 11 can be located anywhere on the flip cover 600. When the flip cover 600 is designed to be thick enough, the battery icon 11 can also be located on the side or front of the flip cover 600, not limited to the top surface. The attached figure is only an example.

[0103] For example, see Figure 13 The portable ultrasound device 200 includes a main unit 500, a handle 700 and a flip cover 600, with a battery icon 11 located on the handle 700.

[0104] Furthermore, the battery icon 11 can be designed at any position on the handle 700, as long as it is easy for the user to see. Common locations include the top surface, the outer side (the side away from the cover plate 10), or the left and right sides of the handle 700. Preferably, the battery icon 11 mainly indicates the position of the lamp body device 20, while the position of the activation device 40 can be different from that of the lamp body device 20. For example, the battery icon 11 can be located on the outer side of the handle 700 for easy observation by the user, while the activation device 40 can be located on the inner side of the handle 700 (the side closer to the cover plate 10). The activation device 40 uses a touch-sensitive sensor, which is triggered when the user's hand grips the handle 700.

[0105] Figure 13 Taking the battery icon 11 on the top surface of the handle 700 as an example, the starter device 40 and the lamp body device 20 are both located inside the handle 700 and are arranged adjacent to each other. It can be understood that the battery icon 11 can be located at any position on the top surface, as long as it is convenient for the installation of the lamp body device 20 and for the user to observe.

[0106] For example, see Figure 14 The portable ultrasound device 200 includes a main unit 500 and a flip cover 600, with a battery icon 11 located on either the main unit 500 or the flip cover 600. Figure 14 Taking the battery icon 11 on the main unit 500 as an example. It can be understood that the battery icon 11 can be located anywhere on the main unit 500 and the flip cover 600. It can be on the top surface of the flip cover 600, the front or back side of the main unit 500, the top side of the main unit 500, the left or right side of the main unit 500, or when the flip cover 600 is designed to be thick enough, it can also be located on the front or back side or the left or right side of the flip cover 600.

[0107] Apart from Figure 10 - Figure 15As can be understood from the example, the structure of the portable ultrasound device 200 is not limited to the combination of the main unit 500, the flip cover 600, and the handle 700. In addition to the main unit 500, the portable ultrasound device 200 may also include a flip cover 600, a handle 700, or any combination of other structures. In this case, the lamp device 20 and the activation device 40 are also adaptively positioned in any position among the main unit 500, flip cover 600, handle 700, or other combinations of structures. Correspondingly, the battery icon 11 can also be exposed in any position that is easy for the user to observe among the main unit 500, flip cover 600, handle 700, or other combinations of structures. It is understood that, in order to make it easier for the user to know the remaining battery power of the portable ultrasound device 200, the battery icon 11 should be exposed and visible to the user at least when the flip cover 600 is attached to the main unit 500. Of course, this includes the situation where the battery icon 11 is always exposed and visible to the user regardless of whether the flip cover 600 is attached to the main unit 500, and it may also include the situation where the battery icon 11 is exposed and visible when the flip cover 600 is attached to the main unit 500. It should be noted that although the example above only shows that the battery icon 11 is exposed for observation, in some embodiments the entire or part of the power display device may be exposed, such as the power display device in the example above that is connected to the host via a plug-in method.

[0108] By setting a battery icon 11 on the cover plate 10 and a lamp device 20 below the battery icon 11 that illuminates the corresponding light source 21 according to the battery level of the battery 300, the remaining battery level of the device can be displayed when the device is not powered on, thus avoiding the need for a second independent display screen for displaying the remaining battery level. Therefore, while achieving a reliable and aesthetically pleasing display, the structure is simple to install and maintain.

[0109] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "back", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0110] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0111] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
