Description

Technical Field

[0001] The present application relates to the medical field, and in particular to a touch panel assembly and a medical device including the touch panel assembly. Background Art

[0002] With the advancement of medical technology, more and more medical devices are being developed for the diagnosis and treatment of diseases. Users usually operate and control medical devices through human-computer interaction devices. A touchpad is a common human-computer interaction device. By operating the touchpad, users can perform a series of operations on medical devices. Conventional touchpads can be touched by fingers in a sliding manner to generate control signals. Furthermore, some touchpads also have the function of being pressed. Users can generate signals different from sliding operations by pressing the touchpad. For example, the touchpad can function as a normal button when pressed.

[0003] As a medical device, ultrasound imaging equipment can be integrated with a pressable touch panel. Users can control the ultrasound imaging equipment through the touch panel and perform ultrasound scanning of patients. For example, during the use of medical equipment such as ultrasound imaging equipment, cleaning and disinfection are very necessary to avoid cross infection between patients or the risk of doctors being infected. Utility Model Content

[0004] The inventors have found in practice that although the depressible touchpad brings the convenience of integrating two different user input methods, it is easy to reduce the reliability of the touchpad. For example, for a depressible touchpad, the touchpad needs to be used as a movable part, which usually requires a gap for the touchpad to move. Especially for a larger touchpad, there may be tilting, swinging, etc. when pressed, so a larger gap is required to avoid the touchpad from getting stuck. The larger gap makes the touchpad easy to be contaminated and difficult to be thoroughly cleaned and disinfected.

[0032] The embodiment of the present application provides a touch panel assembly 101. Please refer to Figure 1 , 2 .in, Figure 1 FIG. 1 shows a perspective exploded view of a touch panel assembly 100 in some embodiments of the present application. Figure 2 FIG. 1 shows a bottom view of a touch panel 101 in some embodiments of the present application. The touch panel assembly 100 may include:

[0033] A touch panel 101, which can be touched to generate a touch signal;

[0034] The base 102 is disposed below the touch panel 101. The outer periphery of the base 102 extends upward by a certain distance to form a wall 121. The wall 121 laterally surrounds the touch panel 101 ( Figure 1 The enclosed state is not shown in the exploded perspective view shown in the figure), the upper surface of the base 102, the wall 121 and the lower surface of the touch panel 101 form a space 122, and the touch panel 101 can move up and down in the space 122;

[0035] The button 103 is disposed on the upper surface of the base 102 or the lower surface of the touch panel 101 (eg Figure 2 In the embodiment shown, it is arranged on the lower surface of the touch panel 101), after the touch panel 101 moves downward under the action of an external force, the button 103 can be squeezed by the touch panel 101 and the base 102 to generate a control signal; and

[0036] A plurality of brackets 104 are disposed in the space 122, one end of each bracket 104 is rotatably connected to one of the upper surface of the base 102 or the lower surface of the touch pad 101, and the other end of each bracket 104 is slidably contacted to the other of the upper surface of the base 102 or the lower surface of the touch pad 101.

[0037] In the above-mentioned embodiment of the present application, by providing a plurality of brackets 104, it is possible to ensure that the touch pad 101 maintains balance and stability as much as possible during the process of being pressed and moving downward, and it is not easy for the end where the force point is located to tilt. Furthermore, the bracket 104 can cooperate with the wall 121 formed by extending a certain distance upward from the periphery of the base 102. Thanks to the above-mentioned stabilizing effect of the bracket 104, even when the wall 121 is provided, it is not easy for the touch pad 101 to collide with the wall 121 and get stuck during the movement. In this way, the lateral spacing between the wall 121 and the touch pad 101 can be set to be relatively small, so that dust is not easy to enter, and the reliability during cleaning and disinfection is also improved.

[0038] It is understandable that Figure 2 In the illustrated embodiment, the button 103 is disposed on the lower surface of the touch panel 101 . However, although not shown, in another embodiment, the button 103 may also be disposed on the upper surface of the base 102 .

[0039] As described above, in the embodiment of the present application, the touch panel 101 can be pressed to move downward. In a further embodiment, the touch panel assembly 100 further includes an elastic member (not shown in the figure). The elastic member is arranged in the space 122, and the elastic member provides a rebound force for the touch panel 101, so that the touch panel 101 can move upward after the external force is eliminated.

[0040] Such a setting can ensure that the touch panel 101 automatically resets after the user finishes pressing the touch panel 101, thereby facilitating the user's next operation.

[0041] The specific structure of the elastic member can be any in the art, for example, a spring, a spring sheet or other materials that have elastic deformation function such as rubber. In addition, although the elastic member can be arranged in the space 122 as an independent component, in a preferred example, the elastic member can be integrated in the button 103, and the elastic member provides resilience for the button 103 and the touch pad 101 at the same time. For example, the elastic member can be a spring inside the button 103. The key on the button 103 can be pressed to produce a change in the electrical signal. At this time, the elastic member inside the button 103 is compressed to generate a resilience force, thereby supporting the keys on the button 103 and the touch pad 101 of the touch pad assembly 100 to reset after the user's pressing force is cancelled. This is very beneficial for a compact touch pad assembly 100, and there is no need to set additional components in a limited space.

[0042] As described above in the present application, by providing a plurality of brackets, it is possible to ensure that the touch pad 101 remains as stable as possible during the up and down movement, thereby creating conditions for providing the wall 121 and minimizing the gap between the wall 121 and the touch pad 101. In a preferred example, the maximum gap between the touch pad 101 and the wall 121 does not exceed 0.5 cm. The maximum gap can be understood as the difference between the inner surface size of the wall 121 and the outer surface size of the touch pad 101. For example, when the touch pad 101 is configured as a circle, the gap can be understood as the difference between the diameter of the touch pad 101 and the inner diameter of the wall 121. Alternatively, when the touch pad 101 is configured as a rectangle, the gap can be understood as the difference between the length / width of the touch pad 101 and the length / width of the internal notch of the wall 121. No further enumeration is given here.

[0043] The bracket can be set in various ways. The following is an exemplary description. Please refer to Figure 1-3 .in, Figure 3 A stereoscopic view of a touch panel assembly in some embodiments of the present application is shown from a bottom-up perspective.

[0044] like Figure 1-3As shown, in some embodiments, the plurality of brackets may include a first bracket 301 and a second bracket 302. The first bracket 301 includes a first upper end 311, a first lower end 312, and a first connecting rod 313 connecting the first upper end 311 and the first lower end 312. The second bracket 302 includes a second upper end 321, a second lower end 322, and a second connecting rod 323 connecting the second upper end 321 and the second lower end 322. The first upper end 311 and the lower surface of the touch pad 101 are rotatably connected, and the first lower end 312 and the upper surface of the base 102 are slidably contacted; the second upper end 321 and the lower surface of the touch pad 101 are slidably contacted, and the second lower end 322 and the upper surface of the base 102 are rotatably connected.

[0045] The above embodiment provides a simple and effective implementation method for the embodiment of multiple brackets. The support effect of the touch panel 101 can be achieved by only providing two brackets, namely the first bracket 301 and the second bracket 302 .

[0046] Further, in some embodiments, the first connecting rod 313 and the second connecting rod 323 are cross-arranged, and the two are rotatably connected via the rotating shaft 303. The two cross-arranged connecting rods can ensure that as the touch pad 101 moves up and down, the first bracket 301 and the second bracket 302 are opened and closed synchronously, further ensuring the stability of the up and down movement. In addition, as described in the above embodiment, the first upper end 311 of the first bracket 301 is rotatably connected to the lower surface of the touch pad 101, and the second upper end 321 of the second bracket 302 is in slidable contact with the lower surface of the touch pad 101 (rather than rotatably connected). In other words, the upper ends of the two brackets are not rotatably connected to the lower surface of the touch pad 101 at the same time, but one of the upper ends can slide. The configuration of the above embodiment of the present application can ensure the fixed connection between the bracket and the touchpad 101 to prevent the touchpad 101 from falling off (the above fixing effect is achieved by the rotatably connected bracket), and can ensure that the two brackets will not be stuck and prevent the touchpad 101 from moving up and down (the two crossed brackets can still be opened by the slidable bracket). In this way, the touchpad 101 can move up and down smoothly and the stable connection between the touchpad 101 and the bracket can be ensured.

[0047] Further, in some examples of the present application, the first upper end 311, the first lower end 312, the second upper end 321, and the second lower end 322 are all extended in the transverse direction to form a crossbar structure; the first connecting rod 313 and the second connecting rod 323 each include two oppositely arranged ones. By extending in the transverse direction to form a crossbar structure, the first and second upper ends and the first and second lower ends can respectively have a larger contact range with the surface of the touchpad and the base, thereby providing better support for the touchpad. The arrangement of the two parallel connecting rods can, on the one hand, ensure that the rotating shaft between the first and second brackets can be set to two, thereby ensuring the reliability of the rotation connection between the connecting rods, and on the other hand, it can also increase the stability of the connecting rod's support for the upper and lower ends.

[0048] The following is an exemplary description of the rotatable and slidable connection of the bracket. Please continue to refer to Figure 1-3 .

[0049] In some examples, the lower surface of the touch panel 101 and the upper surface of the base 102 are respectively provided with a first limiting portion 304 and a second limiting portion 305. A first gap 341 is included between the first limiting portion 304 and the lower surface of the touch panel 101. The first gap 341 partially accommodates the second upper end portion 321, so as to allow the second upper end portion 321 to slide and prevent the second upper end portion 321 from detaching from the lower surface of the touch panel 101. A second gap (similar to the first gap 341) is included between the second limiting portion 305 and the upper surface of the base 102, and the second gap partially accommodates the first lower end portion 312, so as to allow the first lower end portion 312 to slide and prevent the first lower end portion 312 from detaching from the upper surface of the base 102.

[0050] The above-mentioned setting of the limiting part can ensure the stability of the sliding of the first lower end 312 and the second upper end 321, because the first and second gaps can play a guiding role. On the other hand, it can also prevent the first and second lower ends from detaching from the base and the touch panel surface, thereby ensuring the sliding ability and improving the stability of the connection.

[0051] In some examples, the lower surface of the touch panel 101 and the upper surface of the base 102 are respectively provided with a first engaging portion 306 and a second engaging portion 307. The first engaging portion 306 includes a first opening for accommodating the first upper end, and the second engaging portion 307 includes a second opening for accommodating the second lower end.

[0052] Such a configuration can achieve stable and rapid connection between the first upper end portion and the second lower end portion and the lower surface of the touch panel 101 and the upper surface of the base 102 respectively.

[0053] So far, the above embodiments of the present application schematically describe how the first and second brackets are rotationally connected or slidingly contacted with the lower surface of the touchpad or the upper surface of the base. In the above examples of the present application, the implementation methods of the rotational connection and the sliding contact are simple and reliable, and can realize the mutual engagement between the base, the bracket, and the touchpad, which is not only conducive to assembly, but also can maintain the stable connection between the components after assembly. Specifically, the setting of the rotating shaft can facilitate the first and second brackets to be movably and stably connected. Subsequently, the first and second brackets can be fixed to the upper surface of the base or the lower surface of the touchpad. Due to the setting of the engaging portion and the blocking portion, the above fixation is not easy to be separated after completion. Finally, the first and second brackets are fixed to the lower surface of the touchpad or the upper surface of the base, so that the assembly between the various components can be realized. Moreover, due to the engaging relationship between the various components, the base and the touchpad can be simply and efficiently fixed to each other through the bracket, and are not easy to separate.

[0054] It is understood that the above describes a case where the multiple brackets include a first bracket and a second bracket. Under the teachings of the present application, the multiple brackets may also include more brackets, such as three, four or more brackets evenly distributed on a plane. This will not be exhaustively listed here.

[0055] In order to provide better user feedback to the user's operation of pressing the touch pad, some embodiments of the present application also propose improvements. Figure 4 , showing a cross-sectional view of a touch pad assembly in a pressed state in some embodiments of the present application.

[0056] like Figure 4 As shown, in some embodiments, the touch pad assembly of the present application may further include a cylindrical portion. The cylindrical portion includes a cylindrical body 401, a protrusion 402 disposed on the inner surface of one end of the cylindrical body 401, and an opening 403 disposed at the other end of the cylindrical body 401. The opening 403 and the button 103 are disposed opposite to each other. After the touch pad 101 moves downward under the action of an external force ( Figure 4 4 shows the state after the movement), the opening 403 is closed under the pressure of the touch panel 101 and the base 102, and the button 103 and the protrusion 402 are in contact and pressed.

[0057] This arrangement makes use of the hollow structure of the cylindrical portion, and can collect and amplify the sound generated when the button 103 is pressed. The sound waves are reflected by the inner surface of the hollow structure so that the user can perceive it more clearly. In addition, by providing the protrusion 402 on the inner surface of the cylinder 401, it is more convenient to press the button 103. In particular, compared with squeezing the button 103 through a plane, providing the protrusion 402 makes it easier to contact the button 103, and even if the plane has a certain manufacturing tolerance or is bent, the button 103 will not fail to function.

[0058] As described in the above embodiments of the present application, the button 103 may be disposed on one of the lower surface of the touch panel 101 and the upper surface of the base 102. Figure 4 In an optional example, the cylindrical portion 401 is disposed on the upper surface of the base 102, and the button 103 is disposed on the lower surface of the touch pad 101; the upper surface of the base 102 also includes a receiving portion 404, and the receiving portion 404 receives the cylindrical portion.

[0059] Such a setting will facilitate the assembly of the touchpad assembly. Specifically, the accommodating portion 404 can limit the position of the cylindrical portion. During the assembly process, the assembler can easily place the cylindrical portion within the range defined by the accommodating portion 404. After that, the cylindrical portion is not easily misplaced or moved. In addition, during the user's use, the accommodating portion 404 can also continue to limit the position. Even after a long period of pressing, the cylindrical portion 401 is not easily displaced, causing the device to fail.

[0060] It should be noted that the above describes the main components of the touchpad assembly in detail. For the parts not disclosed in the above embodiments of the present application, reference can be made to the prior art. For example, the above embodiments of the present application do not describe the electrical connection part, but the electrical connection part can be any part of the prior art and will not be described in detail. The following is an exemplary description of the key electrical components of the touchpad.

[0061] Please refer to Figure 5 , showing a three-dimensional exploded view of the touch panel in some embodiments of the present application.

[0062] like Figure 5 As shown, the touch panel 101 may include a protective shell 501 and a circuit component 502. The protective shell 501 includes a lower opening 511, and the circuit component 502 is accommodated in the protective shell 501 through the lower opening 511.

[0063] This arrangement can protect the circuit component 502 as much as possible and prevent it from being contaminated by liquid or dust during actual use. The circuit component 502 can be understood as a component that can generate an electrical signal when touched by a finger. Its specific structure and principle can be any in the prior art and will not be described in detail here. Figure 5 In the three-dimensional exploded state, the circuit component 502 is separated from the protective shell, but it should be understood that after actual assembly, the circuit component 502 will be in a structure accommodated in the internal space of the protective shell 501.

[0064] Furthermore, in order to improve the overall reliability of the touch panel 101, the touch panel in some embodiments of the present application is also improved. Figure 5 As shown, the touch panel 101 further includes an upper top plate 503 and a lower bottom plate 504, wherein the upper top plate 503 is connected to the upper surface of the protective shell 501, and the lower bottom plate 504 is connected to the lower surface of the circuit assembly 502. By providing the upper top plate and the lower bottom plate, the electrical components inside the touch panel 101 can be better protected, thereby improving the reliability of the touch panel 101.

[0065] It is understood that the connection modes between the upper plate 503 and the protective shell 501, the protective shell 501 and the circuit assembly 502, and the circuit assembly 502 and the lower plate 504 can be various. Figure 5 The connection is shown as being performed through glue layers 505 , respectively, but other methods are also possible.

[0066] So far, the above embodiments of the present application describe a touchpad assembly including a plurality of brackets. The provision of a plurality of brackets improves the stability of the touchpad in the touchpad assembly when pressed, thereby providing a guarantee for a more stable sealed connection between the touchpad and the wall. The above touchpad assembly of the present application can improve the reliability and sealing of the depressible touchpad.

[0067] The touchpad assembly can be used in different usage scenarios. In some examples, it can be applied to the medical field, thereby providing a convenient human-computer interaction interface for users while taking into account the advantages of being conducive to cleaning and disinfection.

[0068] Some embodiments of the present application also provide a medical device, which may include a touch panel assembly as described in any of the above embodiments of the present application. The types of medical devices may be various, for example, it may be an ultrasound imaging device. Figure 6 An exemplary description is given.

[0069] like Figure 6As shown, a schematic diagram of an ultrasonic imaging device 600 in some embodiments of the present application is shown. The ultrasonic imaging device 600 includes a touch panel assembly 100, a display 601, a host 602 and a button 603. Among them, the touch panel assembly 100 can be described in any embodiment of the present application above, and it can be set on the host 602 in an integrated or detachable manner. The host 602 can contain any component in the prior art that realizes the ultrasonic imaging function, such as a battery, a memory, a processor, etc. The display 601 can display the ultrasonic image generated by the host 602 after processing in real time. In addition to the touch panel assembly 100, the host 602 can also include other user interfaces such as a button 603 for performing the required user input function. By integrating the touch panel assembly 100 recorded in any of the above embodiments of the present application, the user can realize the functions of the touch panel and some buttons by only operating the touch panel assembly 100, thereby improving the convenience of use. In addition, when cleaning and disinfection are required, the touch panel assembly 100 of the present application also has a higher degree of reliability.

[0070] Understandably, Figure 6 The portable ultrasonic imaging device is used as an example for illustration. In another example, the ultrasonic imaging device may be any other type in the art, such as a desktop ultrasonic imaging device. In addition, under the guidance of the present disclosure, the touch panel assembly of the present application may also be used for other required medical devices, which are not listed here.

[0071] The purpose of providing the above specific embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive, but the present application is not limited to these specific embodiments. It should be understood by those skilled in the art that various modifications, equivalent substitutions and changes, etc., may also be made to the present application, as long as these changes do not violate the spirit of the present application, they should all be within the scope of protection of the present application.
