[0031] In order to make the purpose, advantages and features of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0032] Figure 1 The overall structure diagram of the control panel assembly 10 of the ultrasound trolley provided in some embodiments of the utility model is shown. Figure 2 A partial structural schematic diagram of the control panel assembly 10 is shown. Figure 3 A partial exploded schematic diagram of the control panel assembly 10 is shown.

[0033] Please refer to Figures 1 to 3The control panel assembly 10 includes a control panel 100 and a trigger device (not marked in the figure). The trigger device is arranged on the control panel 100 and includes a first button 210 and a second button 220. The first button 210 and the second button 220 are arranged at different positions. The second button 220 includes a plurality of button units 221 (such as Figure 4 The trigger device 300 is configured to control the switch of the button unit 221 based on the switch state of the first button 210, specifically, when the first button 210 is turned on, any of the button units 221 is allowed to be turned on, and when the first button 210 is turned off, any of the button units 221 is prevented from being turned on. The configuration of the trigger device 300 effectively reduces or even avoids the situation where the control panel assembly 10 has unexpected movement.

[0034] Specifically, each of the button units 221 is configured to control the movement of the control panel assembly 10 in at least one direction. For example, the second button 220 includes three button units 221, namely a first button unit 221a, a second button unit 221b, and a third button unit 221c (e.g., Figure 4 As shown in FIG. 1 , the first button unit 221a controls the upward movement of the control panel assembly 10, the second button unit 221b controls the downward movement of the control panel assembly 10, and the third button unit 221b controls the forward and backward movement of the control panel assembly 10. When the first button unit 221a is turned on, the control panel assembly 10 is allowed to move upward under the action of the force applied by the operator, and when the first button unit 221a is turned off, the control panel assembly 10 is prevented from moving upward; when the second button unit 221b is turned on, the control panel assembly 10 is allowed to move downward under the action of the force applied by the operator, and when the second button unit 221b is turned off, the control panel assembly 10 is prevented from moving downward; when the third button unit 221c is turned on, the control panel assembly 10 is allowed to move forward or backward under the action of the force applied by the operator, and when the third button unit 221c is turned off, the control panel assembly 10 is prevented from moving forward or backward. By setting the first button 210 and configuring that only when the first button 210 is turned on can one of the first button unit 221a, the second button unit 221b, and the third button unit 221c be turned on, so that the turning on of any of the button units 221 requires two steps, the situation where the operator turns on any of the button units 221 by mistake can be effectively reduced.

[0035] It should be understood that the first button 210 and the second button 220 are connected in series, and the plurality of button units 221 are connected in parallel. Such a hardware configuration can achieve the aforementioned purpose.

[0036] Optionally, please continue to refer to Figures 1 to 3 The control panel 100 includes a panel body 110 and an operating unit 120, and the operating unit 120 is disposed on the panel body 110. When any of the button units 221 is turned on, the operator applies a force to the operating unit 120 to drive the control panel assembly 10 to move in a corresponding direction.

[0037] In some exemplary embodiments, the operating portion 120 is a handle for the operator to hold. The style of the handle can be as follows: Figures 1 to 3 As shown, it is arranged at one side of the panel body 110. In this regard, the operator's habitual operation is: holding the operating portion 120 while manipulating the key unit 221. It should be understood that when the key unit 221 is a mechanical key, manipulating the key unit 221 means pressing the key unit 221, and when the key unit 221 is a touch key such as a capacitive touch key, manipulating the key unit 221 means touching the key unit 221.

[0038] In a preferred embodiment, the key unit 221 is a touch key such as a capacitive touch key. Compared with a mechanical key, the advantages of a capacitive touch key are: no complex mechanical structure, small size, small installation space required, which is conducive to the thin and light design of the key unit 221 itself and the operating unit 120, and there is no mechanical wear, so there is no problem of mechanical life limit, and theoretically it can achieve unlimited life; the configurations of multiple key units 221 are basically the same, so that multiple key switches 221 have basically the same feel, which is conducive to improving the operator's operating experience.

[0039] Optionally, the first button 210 is also a touch button, and specifically may be a capacitive touch button.

[0040] In the case where both the first button 210 and the button unit 221 are the touch buttons, it is preferred that the first button 210 is also provided on the operating unit 120, and when the operator holds the operating unit 120, the operator's hand can contact the first button 210 and the second button 220 at the same time, for example, the operator's palm contacts the first button 210, and the operator's thumb selectively contacts one of the button units 221. Figures 1 to 3In the control panel assembly 10 shown, the first button unit 210 may be arranged on any one of the inner side, upper side, and lower side of the operating portion 120, and the second button unit 220 is arranged on the outer side of the operating portion 120. It should be understood that the inner side of the operating portion 120 refers to the portion of the outer surface of the operating portion 120 facing the panel body 110, the upper side of the operating portion 120 refers to the portion of the outer surface of the operating portion 120 facing upward, the lower side of the operating portion 120 refers to the portion of the outer surface of the operating portion 120 facing downward, and the outer side of the operating portion 120 refers to the portion of the surface of the operating portion 120 facing away from the panel body 10.

[0041] Furthermore, the trigger device is further configured to turn on the first button 210 when the operator touches the first button 210 for a first predetermined time, and turn off the first button 210 when the operator stops touching the first button 210; and under the premise that the first button 210 is turned on, when the operator touches any of the button units 221 for a second predetermined time, the touched button unit 221 is turned on, and turn off the button unit 221 when the operator stops touching the button unit 221. Such a control method can further reduce the possibility of the operator accidentally turning on any of the button units 221.

[0042] In addition, it should be noted that, under the premise that the first button 210 is turned on, the operator can only turn on one button unit 221 at a time, and cannot turn on more than two button units 221 at the same time.

[0043] The touch-type key itself cannot generate feedback to the operator's touch, which makes it difficult for the operator to determine whether the touch of the key unit 221 has achieved the opening of the corresponding key unit 221, and thus cannot determine whether the control panel assembly 10 can be started to move. In view of this, the control panel assembly 10 also includes a prompt mechanism, which is arranged on the control panel 100, is connected to the second key 220, and is configured to generate prompt information when any of the key units 221 is turned on. That is, the prompt mechanism provides feedback to the operator's touch operation on the key unit 221, so that the operator can know in time whether the touched key unit 221 is turned on.

[0044] It should be noted that the prompt mechanism and the second button 220 can be directly communicated and connected, or can be indirectly communicated and connected via other devices, for example, through a control mechanism (such as the control board 400 and external control device described later), that is, the prompt mechanism is communicated and connected with the control mechanism, and the control mechanism is communicated and connected with the second button 220, so that when any button unit 221 is touched and triggered, the control mechanism receives the signal that the button unit 221 is triggered, and generates a corresponding prompt control signal, and sends the prompt control signal to the prompt mechanism, so that the prompt mechanism generates corresponding prompt information according to the prompt control signal.

[0045] The embodiment of the utility model has no special limitation on the specific structure of the prompt mechanism, as long as it can play a feedback role.

[0046] In some embodiments, the prompting mechanism includes: Figure 1 The light prompt element 310 shown is configured to generate a light corresponding to the key unit 221 as at least a part of the prompt information when any of the key units 221 is turned on.

[0047] For example, the light prompt element 310 includes one or more lamp beads, and when the first key unit 221a is turned on, the light prompt element 310 generates a light of a first color and keeps it on, when the second key unit 221b is turned on, it generates a light of a second color and keeps it on, and when the third key unit 221c is turned on, it generates a light of a third color and keeps it on, and the third color, the second color, and the third color are different. That is, the operator determines whether any of the key units 221 are turned on according to whether the light prompt element 310 is always on, and determines which key unit 221 is turned on according to the color of the light emitted by the light prompt element 310.

[0048] For another example, the light prompt element 310 includes a plurality of lamp beads (not shown in the figure), and the plurality of lamp beads are arranged one-to-one with the plurality of the key units 221, that is, the light prompt element 310 includes a first lamp bead corresponding to the first key unit 221a, a second lamp bead corresponding to the second key unit 221b, and a third lamp bead corresponding to the third key unit 221c. When the first key unit 221a is turned on, the first lamp bead is turned on and remains on; when the second key unit 221b is turned on, the second lamp bead is turned on and remains on; when the third key unit 221c is turned on, the third lamp bead is turned on and remains on. In this case, the first lamp bead, the second lamp bead, and the third lamp bead can be distinguished by locating the first lamp bead, the second lamp bead, and the third lamp bead in different positions. That is, the operator determines whether the key unit 221 is turned on according to whether the light prompt element 310 is always on, and when the first lamp bead, the second lamp bead, and the third lamp bead are in different positions, the operator determines which key unit 221 is turned on according to the position of the light.

[0049] For another example, when the first key unit 221a is turned on, the light prompt element 310 emits light and flashes at a first frequency, when the second key unit 221b is turned on, the light prompt element 310 emits light and flashes at a second frequency, and when the third key unit 221c is turned on, the light prompt element 310 emits light and flashes at a third frequency. The third frequency, the second frequency, and the first frequency are different. Thus, the operator can determine whether the key unit 221 is turned on according to whether the light prompt element 310 flashes, and determine which key unit 221 is turned on according to the flashing frequency of the light prompt element 310.

[0050] In other embodiments, the prompting mechanism includes: Figure 2 and Figure 3 The vibration prompt element shown in the figure may specifically include a vibration motor 320. The vibration motor 320 is configured to vibrate when any of the button units 221 is turned on to serve as at least a part of the prompt information.

[0051] Optionally, the vibration parameters of the vibration motor 320 corresponding to each of the button units 221 are the same, that is, when any of the button units 221 is turned on, the vibration motor 320 vibrates, and the vibration duration is the first duration, the vibration frequency is the fourth frequency, and the vibration amplitude is the first amplitude. In this case, the operator can only know that a button unit 221 is turned on through the vibration of the vibration motor 320, but cannot determine which button unit 221 is turned on.

[0052] Alternatively, the vibration parameters of the vibration motor 320 corresponding to each of the buttons 221 are not completely the same, that is, at least one of the vibration duration, vibration frequency, and vibration amplitude is different. For example, only the vibration duration is different, that is, when the first button unit 221a is turned on, the vibration duration of the vibration motor 320 is the first duration, the vibration frequency is the fourth frequency, and the vibration amplitude is the first amplitude; when the second button unit 221b is turned on, the vibration duration of the vibration motor 320 is the second duration, the vibration frequency is the fourth frequency, and the vibration amplitude is the first amplitude; when the third button unit 221c is turned on, the vibration duration of the vibration motor 320 is the third duration, the vibration frequency is the fourth frequency, and the vibration amplitude is the first amplitude, and the first duration, the second duration, and the third duration are different.

[0053] For another example, the vibration duration and vibration frequency of the vibration motor 320 are different, but the vibration amplitude is the same. That is, when the first button unit 221a is turned on, the vibration duration of the vibration motor 320 is the first duration, the vibration frequency is the fourth frequency, and the vibration amplitude is the first amplitude; when the second button unit 221b is turned on, the vibration duration of the vibration motor 320 is the second duration, the vibration frequency is the fifth frequency, and the vibration amplitude is the first amplitude; when the third button unit 221c is turned on, the vibration duration of the vibration motor 320 is the third duration, the vibration frequency is the sixth frequency, and the vibration amplitude is the first amplitude; the first duration, the second duration, and the third duration are different, and the fourth frequency, the fifth frequency, and the sixth frequency are different.

[0054] For another example, the vibration duration, vibration frequency, and vibration amplitude of the vibration motor 320 are all different. Or only the vibration frequency is different. Or only the vibration amplitude is different. Or the vibration duration is the same, but the vibration frequency and vibration amplitude are different, or the vibration frequency is the same, but the vibration duration and vibration amplitude are different, etc.

[0055] In some other embodiments, the prompt mechanism includes a sound prompt element (not shown in the figure). The sound prompt element can be set at any suitable position of the control panel 100, and is configured to generate a prompt sound when any of the key units 221 is turned on. The prompt sound here can be a "beep" sound, a voice broadcast, or any other suitable sound.

[0056] It can be understood that the prompt mechanism can also include at least two of the light prompt element 310, the vibration prompt element, and the sound prompt element.

[0057] In an exemplary embodiment, if Figure 2 and Figure 3As shown, the prompt mechanism includes the light prompt element 310 and the vibration motor 320, and the light prompt element 310 includes a first lamp bead corresponding to the first button unit 221a, a second lamp bead corresponding to the second button unit 221b, and a third lamp bead corresponding to the third button unit 221c. Next, the specific assembly of the prompt mechanism, the second button 220, the first button 210 and the operating part 120 in this exemplary embodiment is introduced, taking the operating part 120 as a handle, and the first button 210 installed on the inner wall of the operating part 120, and the second button 220 installed on the outer wall of the operating part 120 as the handle as an example.

[0058] Please refer to Figure 1 Combined with Figure 2 , Figure 3 The operation part 120 includes a shell 121, and the shell 121 is a hollow structure with an inner cavity 121. Therefore, the shell 121 includes an outer wall, an upper side wall, an inner side wall and a lower side wall (not marked in the figure) connected in sequence. The outer wall is the side wall of the shell 121 away from the panel body 110, the upper side wall and the lower side wall are opposite to each other in the vertical direction, and the upper side wall is located below the lower side wall, and the inner side wall is the side wall of the shell 121 close to the panel body 110. The outer surface of the outer wall is the outer side surface of the operation part 120, the outer surface of the upper side wall is the upper side surface of the operation part 120, the outer surface of the inner side wall is the inner side surface of the shell operation part 120, and the outer surface of the lower side wall is the lower side surface of the operation part 120.

[0059] The outer wall of the shell 121 is provided with a first mounting groove 123, and the notch of the first mounting groove 123 is on the outer surface of the operating part 120. The light prompting element 310 has a first surface and a second surface (not marked in the figure) opposite to each other, and the first surface and the second surface are both provided with adhesive, and the second surface is also provided with a plurality of lamp beads. The first surface is connected to the bottom of the first mounting groove 310 through the adhesive thereon. The second surface faces the notch of the first mounting groove 123. The second button 220 is bonded to the light prompting element 310 through the adhesive on the second surface, so that the second button 220 is located on the side of the light prompting element 310 close to the notch of the first mounting groove 123. At the same time, the plurality of button units 221 are arranged one by one with the plurality of lamp beads. Each button unit 221 is also provided with a light-transmitting portion 222. In this way, when any of the button units 221 is turned on and the corresponding lamp bead is lit, the light emitted by the lamp bead can pass through the light-transmitting portion 222 and be visible to the outside, so that the operator can know that the button unit 221 he touches is turned on based on the light he sees.

[0060] It should be noted that the shapes of the light-transmitting portions 222 on the various key units 221 can be the same or different. Also, after the key units 221 are bonded to the light prompt unit 310, the various lamp beads are isolated from each other. Therefore, when the operator touches a key unit 221 and turns on the key unit 221 and the corresponding lamp bead, the light emitted by the lamp bead can only pass through the light-transmitting portion 222 of the touched key unit 221, and will not pass through the light-transmitting portions 222 of other key units 221. In this way, the operator can determine which key unit 221 is turned on based on the light he sees.

[0061] Preferably, after the second button 220 is bonded to the light prompt element 310, the outer surface of the second button 220 is flush with the outer side surface of the operating part 120 and completely closes the first mounting groove 123. In this way, there is no gap at the first mounting groove 123, which does not affect the aesthetics of the outer side surface of the control panel assembly 10 and can also prevent liquid from entering the inner cavity 122 from the first mounting groove 123, thereby avoiding adverse effects on the components in the inner cavity 122.

[0062] The vibration motor 320 is disposed in the inner cavity 122 and abuts against the housing 121 at a position corresponding to the first mounting groove 123. In this way, the vibration of the vibration motor 320 can be transmitted to the bottom of the first mounting groove 123, and then sequentially transmitted to the second button 220 and the thumb of the operator, so as to be felt by the operator.

[0063] A second mounting groove 124 is provided on the inner wall of the operating part 120, and the first button 210 is arranged in the second mounting groove 124, and preferably the outer surface of the first button 210 is flush with the outer surface of the operating part 120, so that there is no gap at the second mounting groove 124, which does not affect the aesthetics of the outer surface of the control panel assembly 10 and can also prevent liquid from entering the inner cavity 122 from the second mounting groove 124, thereby avoiding adverse effects on the components in the inner cavity 122.

[0064] It is understandable that a first wire hole 125 is provided on the bottom of the first mounting groove 123, and the first mounting groove 123 is connected to the inner cavity 122 through the first wire hole 125. A second wire hole (not shown in the figure) is provided on the bottom of the second mounting groove 124, and the second mounting groove 124 is connected to the inner cavity 122 through the second wire hole. The control panel assembly 10 also includes a control board 400, which is arranged in the inner cavity 122 and includes a control chip, and the control chip is connected to the external control device. The cable of the vibration motor 320 is connected to the control board 400, the cable of the light prompt element 310 and the cable of the second button 220 pass through the first wire hole 125, enter the inner cavity 122 and are connected to the control board 400, and the cable of the first button 210 passes through the second wire hole, enters the inner cavity and is connected to the control board 400. In this way, when the operator touches the first button 210 and any one of the button units 221, or the operator stops touching the first button 210 and the corresponding button unit 221, the capacitance values ​​of the first button 210 and the button unit 221 change and generate corresponding signals. The control chip of the control board 400 receives the signals and transmits the signals to an external control device. The external control device can control the first button unit 210 and the button unit 221 to perform corresponding actions (on or off), and at the same time control the light prompt element 310 and the vibration motor 320 to perform corresponding actions.

[0065] It should be noted that the housing 121 is an assembled structural member, which includes a first sub-housing and a second sub-housing. In an optional embodiment, the first sub-housing may include an outer side wall, a lower side wall and an inner side wall of the housing 121, and the second sub-housing includes an upper side wall of the housing 121. In the process of assembling the first button 210, the second button 220, the light prompt element 310, the vibration motor 320 and the control board 400 to the operating part 120, the first sub-housing and the second sub-housing are separated from each other, and the inner cavity 122 is partially opened to facilitate the installation of the vibration motor 320 and the control board 400, and to facilitate the connection of the cables of the first button 210, the second button 220 and the light prompt element 310 to the control board 400.

[0066] Further, the control chip of the control board 400 is also configured to automatically perform capacitance threshold calibration according to a setting program. Those skilled in the art know that before the control board 400 leaves the factory, the control chip thereon obtains the first capacitance threshold and the second capacitance threshold by learning, and the first capacitance threshold and the second capacitance threshold can both be change rates. The first capacitance threshold and the second capacitance are both burned into the control chip, and the first capacitance threshold is used to determine whether the first button 210 is turned on, and the second capacitance threshold is used to determine whether the button unit 221 is turned on. Specifically, when the capacitance change of the first button 210 when being touched is greater than or equal to the first capacitance threshold, it is determined that the first button 210 should be turned on, and when the capacitance change of the first button 210 is less than the first capacitance threshold, it is determined that the first button 210 is not turned on; when the capacitance change of the touched button unit 221 is greater than or equal to the second capacitance threshold, it is determined that the touched button unit 221 should be turned on, and when the capacitance change of the button unit 221 is less than the second capacitance threshold, it is determined that the button unit 221 is not turned on. During the actual application of the control board 400, the first capacitance threshold and the second capacitance threshold are corrected according to the set time and based on the current application environment, and the old first capacitance threshold is replaced by the new first capacitance threshold, and the old second capacitance threshold is replaced by the new second capacitance threshold, so that the first capacitance threshold and the second capacitance threshold can be adapted to the current environment, avoiding failure caused by the incompatibility of the first capacitance threshold and the second capacitance threshold with the application environment.

[0067] In addition, as mentioned above, each of the key units 221 has substantially the same operational feel. To facilitate the operator to accurately distinguish each of the key units 221 during blind operation, in a further preferred embodiment, a blind spot 223 is further provided on each of the key units 221, and preferably, the blind spots 223 on each of the key units 221 are different. Different blind spots 223 refer to different shapes of the blind spots 223, or the same shapes but different sizes of the blind spots 223, or the same shapes of parts of the blind spots 223, and different shapes of parts, and a part of the blind spots 223 with the same shape is a convex structure and another part is a concave structure, etc. It is sufficient as long as the operator can distinguish each of the key units 221 by touching each blind spot 223.

[0068] It should also be noted that the second button 220 includes a button body 220a and a covering layer 220b, and the covering layer 220b covers one surface of the button body 220a. When the second button 220 is assembled into the first mounting groove 123, the button body 220a is bonded to the light prompt element 310, and the surface of the covering layer 220b facing away from the button body 220a is flush with the outer surface of the operating portion 120. Each of the blind spots 223 is arranged on the covering layer 220b. When the button body 220a is a transparent member, each of the light-transmitting portions 222 is arranged on the covering layer 220b. When the button body 220a is a non-transparent member, a portion of each of the light-transmitting portions 222 is located on the button body 220b, and the other portion is correspondingly arranged on the covering layer 220b.

[0069] Furthermore, the embodiment of the utility model also provides an ultrasound trolley, comprising an ultrasound host and the aforementioned control panel assembly 10 of the ultrasound trolley, wherein the control panel 100 is connected to the ultrasound host.

[0070] Although the utility model is disclosed as above, it is not limited thereto. Those skilled in the art may make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
