Description

Technical Field

[0001] This application relates to the technical field of medical devices, specifically to a keyboard and an ultrasound device. Background Technology

[0002] Ultrasound diagnostic devices are non-invasive techniques for measuring the internal structure of organisms. They transmit ultrasound signals into the organism, receive the reflected ultrasound signals, and process the reflected ultrasound signals to obtain ultrasound images for diagnosis.

[0003] Existing ultrasound diagnostic devices generally include a main unit, a control platform mounted on the main unit, and a keyboard assembly mounted on the control platform. The keyboard assembly includes a trackball, several first keys arranged around the trackball, and several second keys distributed outside the trackball. The keyboard assembly also includes an interconnected circuit board and a panel. The circuit board is located below the panel, and both the circuit board and the panel have mounting holes that communicate with each other. A mounting component is connected below the circuit board, and the trackball is rotatably mounted within the mounting hole, with its tip extending above the hole. Each first key and each second key includes a self-resetting silicone button and a first keycap attached to it. The panel has several through holes for the silicone buttons to pass through. A silicone pad is placed between the circuit board and the panel. The silicone buttons of the first and second keys protrude from the silicone pad towards the direction opposite to the circuit board. A first terminal is located on the circuit board corresponding to the position of the silicone button, and a second terminal corresponding to the first terminal is located on the circuit board facing the position of the silicone button. When the operator presses the first keycap, the silicone button moves towards the circuit board, causing the second terminal on the silicone button to contact the corresponding first terminal on the circuit board, thus inputting information.

[0004] The keyboard assembly described above has the first key positioned around the trackball to effectively shorten the distance the operator needs to travel when switching between the first key and the trackball. This arrangement results in a larger area covered by the first key. In addition, the silicone key is relatively soft. If the operator's pressing direction is not vertically downward, the silicone key and the first keycap may shift together, causing the second terminal to shift relative to the first terminal and fail to connect with it, resulting in key failure and seriously affecting the stability of the keyboard assembly. Summary of the Invention

[0005] The purpose of this application is to overcome the defect of existing trackball-based designs where the first button covers a large area and is made of soft silicone. If the operator does not press the first button vertically downwards, the silicone button and the first button may shift together, causing the second terminal to shift relative to the first terminal and fail to connect with the first terminal, resulting in button failure.

[0006] To address this, this application provides a keyboard, including a trackball, a plurality of first keys arranged around the trackball, and a mounting frame suitable for mounting the first keys. The mounting frame surrounds the trackball. Each first key includes a first reset button that can be automatically reset and a first keycap covering the first reset button. The mounting frame has a plurality of first through holes for the first reset buttons to pass through. The side of the first keycap facing the mounting frame has a insertion groove, which surrounds the first keycap. The side of the mounting frame facing the first keycap has a plurality of inserts. Each first through hole is surrounded by a plurality of inserts. When the first keycap is mounted on the mounting frame, the plurality of inserts can be slidably inserted into the insertion groove of the corresponding first keycap. The inserts have protrusions suitable for sliding abutting against the side wall of the insertion groove.

[0007] Furthermore, the surface of the protrusion is an arc-shaped surface.

[0008] Furthermore, the mounting frame has several protruding frames on the side facing the first keycap. The protruding frames correspond one-to-one with the first through holes and are arranged around the first through holes. When the first keycap is installed on the mounting frame, the protruding frames are slidably inserted into the corresponding insertion slots of the first keycap, and the insertion blocks are arranged on the protruding frames.

[0009] Furthermore, the protruding frame is provided with a first groove, the opening of the first groove faces the first keycap, the bottom of the plug is fixed to the bottom of the first groove, and the gap between the plug and the side wall of the first groove is set.

[0010] Furthermore, the cross-sections of the first reset button, the first keycap, and the protruding frame are all similar polygons, the shape of the first through hole matches the first reset button, and several inserts are evenly distributed on each side of the protruding frame.

[0011] Furthermore, the keyboard also includes a circuit board, a reset pad, and a panel connected sequentially from bottom to top. A mounting frame is disposed between the reset pad and the panel. Mounting holes are provided on the circuit board, the reset pad, the mounting frame, and the panel. The mounting holes on the circuit board, the reset pad, the mounting frame, and the panel are interconnected. The trackball is rotatably inserted through the mounting hole, and the top of the trackball extends above the panel. The first reset button is disposed on the reset pad.

[0012] Furthermore, the circuit board is provided with a plurality of first terminals corresponding to the position of the first button. The first terminals are located on the side of the circuit board facing the first reset button, and the side of the first reset button facing the circuit board is provided with a plurality of second terminals suitable for communicating with the first terminals.

[0013] Furthermore, the keyboard also includes several second keys, each of which includes a second reset key and a second keycap covering the second reset key, and the panel has a second through hole for the second reset key to pass through.

[0014] Furthermore, the size of the mounting hole in the panel is larger than the size of the mounting hole in the mounting frame, and the first keycap is located in the mounting hole in the panel.

[0015] This application also provides an ultrasonic device that includes the aforementioned keyboard.

[0016] If the operator presses the first keycap in a direction other than vertical, the keyboard of this application, through the cooperation of the insert block surrounding the first through hole and the insertion slot of the first keycap, can prevent the first keycap from moving in a direction parallel to the plane of the keyboard. This reduces the possibility of the first reset key and the first keycap shifting, thereby reducing the possibility of the first key malfunctioning and improving the stability of the first key's operation over a large area. Furthermore, the cooperation between the insert block and the insertion slot of the first keycap allows the first keycap to be detachably connected to the mounting frame, facilitating the removal and installation of the first keycap and thus making cleaning easier.

[0032] Example 1

[0033] Reference Figures 1-9Embodiment 1 provides a keyboard, including a trackball 1, a plurality of first keys 2 arranged around the trackball 1, and a mounting frame 3 suitable for mounting the first keys 2. The mounting frame 3 is arranged around the trackball 1. Each first key 2 includes a first reset key 21 that can be automatically reset and a first keycap 22 covering the first reset key 21. The mounting frame 3 is provided with a plurality of first through holes 31 for the first reset key 21 to pass through. The side of the first keycap 22 facing the mounting frame 3 is provided with a insertion groove 221, which is arranged around the first keycap 22. The side of the mounting frame 3 facing the first keycap 22 is provided with a plurality of inserts 32. Each first through hole 31 is surrounded by a plurality of inserts 32. When the first keycap 22 is mounted on the mounting frame 3, the plurality of inserts 32 are slidably inserted into the insertion groove 221 of the corresponding first keycap 22. The inserts 32 are provided with protrusions 321 that are suitable for sliding abutting against the side wall of the insertion groove 221.

[0034] In the aforementioned keyboard, if the operator presses the first keycap 22 in a direction that is not vertical, the engagement of the insert block 32 surrounding the first through hole 31 and the insertion slot 221 of the first keycap 22 prevents the first keycap 22 from moving in a direction parallel to the keyboard plane. This reduces the possibility of the first reset key 21 and the first keycap 22 shifting, thereby reducing the possibility of the first key 2 malfunctioning and improving the stability of the first key 2, which covers a large area. Furthermore, the engagement of the insert block 32 and the insertion slot 221 of the first keycap 22 allows the first keycap 22 to be detachably connected to the mounting frame 3, facilitating the installation and removal of the first keycap 22 and thus making it easier to clean.

[0035] In some embodiments, refer to Figures 1-9 The protrusion 321 has an arc-shaped surface. This arc-shaped surface reduces the friction between the first keycap 22 and the protrusion 321 when the first keycap 22 slides, making the sliding of the first keycap 22 smoother. Specifically, the insert 32 is made of a material with a certain degree of elasticity. When the operator installs the first keycap 22, a certain force is applied to insert the insert 32 into the insertion slot 221 of the first keycap 22 to install the first keycap 22. When it is necessary to remove the first keycap 22, the operator applies a certain force to pull the keycap away from the mounting frame 3. The insert 32 and the insertion slot 221 separate under the action of a certain force, thereby removing the first keycap 22 for easy cleaning. When the first keycap 22 is installed on the mounting frame 3 by the operator, the operator presses the first keycap 22, and the first keycap 22 slides towards the mounting frame 3. When the first reset key 21 is reset, the force exerted by the first reset key 21 on the first keycap 22 is much less than the force that separates the plug 32 from the plug slot 221, so the first keycap 22 can be made to work.

[0036] In some embodiments, refer to Figures 1-9 The mounting frame 3 has several protruding frames 33 on the side facing the first keycap 22. Each protruding frame 33 corresponds to and surrounds a first through hole 31. When the first keycap 22 is mounted on the mounting frame 3, the protruding frame 33 slides into the corresponding insertion slot 221 of the first keycap 22, and the insertion block 32 is positioned on the protruding frame 33. The protruding frames 33 further restrict the movement of the first keycap 22 in a direction parallel to the keyboard plane, further reducing the possibility of misalignment between the first reset button 21 and the first keycap 22, thereby further improving the stability of the first key 2, which spans a large area. In addition, the protruding frames 33 can cover the gap between the first keycap 22 and the mounting frame 3, reducing the possibility of dust entering the keyboard through the gap, thus reducing the likelihood of dust affecting the keyboard.

[0037] In some embodiments, refer to Figures 1-9 The protruding frame 33 has a first groove 331, the opening of which faces the first keycap 22. The bottom of the insert 32 is fixed to the bottom of the first groove 331, and a gap is provided between the sidewalls of the insert 32 and the first groove 331. By creating the first groove 331 and providing a gap between the sidewalls of the insert 32 and the first groove 331, a little space is provided for the slight swinging of the insert 32, facilitating the removal of the first keycap 22. Specifically, the insert 32, the protruding frame 33, and the mounting frame 3 are integrally formed, and the first groove 331 can be an opening that is recessed in a direction away from the first keycap 22.

[0038] In some embodiments, refer to Figures 1-9 The first reset button 21, the first keycap 22, and the protruding frame 33 all have similar polygonal cross-sections. The shape of the first through hole 31 matches the first reset button 21, and several inserts 32 are evenly distributed on each side of the protruding frame 33. Firstly, setting the first reset button 21 and the first keycap 22 as polygons allows for a more reasonable distribution of the multiple first keycaps 22, and the size of each first reset button 21 can be inconsistent. Secondly, the presence of inserts 32 on each side of the protruding frame 33 prevents the first keycaps 22 from moving in a direction parallel to the plane of the keyboard, further improving the stability of the first keycaps 22. Specifically, the first button 2 can be quadrilateral, meaning the first reset button 21, the first keycap 22, and the protruding frame 33 all have similar quadrilateral cross-sections. All the first keycaps 22 are arranged around the outer periphery of the trackball 1, facilitating the operator's switching between the trackball 1 and the first button 2.

[0039] In some embodiments, refer to Figures 1-9The keyboard also includes a circuit board 4, a reset pad 5, and a panel 6 connected sequentially from bottom to top. A mounting frame 3 is positioned between the reset pad 5 and the panel 6. Mounting holes 7 are provided on the circuit board 4, reset pad 5, mounting frame 3, and panel 6, and these mounting holes 7 are interconnected. A trackball 1 is rotatably inserted into the mounting hole 7, with its top extending above the panel 6. A first reset button 21 is located on the reset pad 5. Specifically, the circuit board 4 is connected to the panel 6. Both the first reset button 21 and the reset pad 5 are made of silicone and are integrally molded. The first reset button 21 is a groove protruding from the surface of the reset pad 5, with its opening on the same plane as the reset pad 5, and the opening of the groove facing the circuit board 4. The first reset button 21 and the reset pad 5 are connected by a ramp to achieve automatic reset of the first reset button 21.

[0040] In some embodiments, refer to Figures 1-9 The mounting hole 7 of panel 6 is larger than the mounting hole 7 of mounting frame 3, and the first keycap 22 is located in the mounting hole 7 of panel 6. Specifically, mounting frame 3 is sandwiched between panel 6 and reset pad 5. The part of mounting frame 3 used to install the first keycap 22 is located in the mounting hole 7 of panel 6 so that the first keycap 22 can be removed without removing panel 6, which facilitates cleaning and disassembly of the first keycap 22.

[0041] In some embodiments, refer to Figures 1-9 The circuit board 4 is provided with a plurality of first terminals 41 corresponding to the position of the first button 2. The first terminals 41 are located on the side of the circuit board 4 facing the first reset button 21. The side of the first reset button 21 facing the circuit board 4 is provided with a plurality of second terminals 211 suitable for communicating with the first terminals 41. When the operator presses the first button 2, the first reset button 21 moves toward the direction of the circuit board 4 so that the second terminals 211 can contact the first terminals 41, so that the first button 2 can work normally after being pressed by the operator.

[0042] In some embodiments, refer to Figures 1-9 The keyboard also includes several second buttons 8 distributed on the side of the first button 2 away from the trackball 1. Each second button 8 includes a second reset button 81 and a second keycap 82 covering the second reset button 81. The panel 6 has a second through hole 9 for the second reset button 81 to pass through, and the second through hole 9 corresponds one-to-one with the second button 8. The second buttons 8 are conventional keyboard buttons. Specifically, the second reset button 81 is integrally formed with the reset pad 5, just like the first reset button 21, and the reset structure of the second reset button 81 is the same as that of the first reset button 21.

[0044] Example 2 provides an ultrasound device, which includes a main unit (not shown in the figure), a control platform 002 disposed on the main unit, and a keyboard 001 as described in Example 1 disposed on the control platform 002.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
