The more keys there are, the larger the area of the soldering surface of the PCB board they occupy, and the larger the space occupied by the PCB board in the medical device. At the same time, the keys themselves have a certain height. If the keys are arranged on the soldering surface, the thickness of the medical device will increase.
[0003] In summary, the key structure of the existing technology has low space utilization rate and large thickness, resulting in large thickness and volume of the medical device and being not easy to carry. Utility Model Content

Detailed implementation manners
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the description of the present application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification, claims or drawings of this application are used to distinguish different objects and not to describe a specific order.
[0032] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appearing in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0033] Figure 1 The Z - direction in it is the height direction, which is also the up - down direction. Figure 3 The Y - direction in it is the thickness direction, which is also the front - back direction. Figure 3 The X - direction of is the length direction, which is also the left - right direction.
[0034] Please refer to Figures 1 to 4 , the embodiment of the present application provides a key structure 10, and the key structure 10 includes a PCB board 100 and a key 200, where:
[0035] The PCB board 100 is provided with a welding surface 101 and a side surface 102. The side surface 102 is arranged around the welding surface 101 and intersects with the welding surface 101; the key 200 is arranged on the side surface 102, and the key 200 is connected to the PCB board 100.
[0036] In this embodiment, since the key 200 is located on the side surface 102 rather than the welding surface 101, and the welding surface 101 intersects with the PCB board 100, the setting of the key 200 will not increase the area of the welding surface 101, thereby avoiding increasing the volume of the PCB board 100 and the key structure 10. That is, in the case of the same welding - surface area, more components can be arranged on the PCB board 100 of the key structure 10 in this embodiment. At the same time, as shown in Figure 1 and Figure 3 , the height of the key 200 does not affect the thickness of the key structure 10, so the key structure 10 is thinner. In summary, the key structure 10 in this embodiment has high space utilization rate and small thickness.
[0037] It should be understood that the connection methods between the key 200 and the PCB board 100 include welding, clamping, abutting, etc. When the key 200 is pressed or touched by hand, the PCB board 100 can receive an electrical signal and then make corresponding processing. The side surface 102 and the welding surface 101 can be vertically distributed. The key 200 can be a touch key 200, an elastic key 200, a mechanical key 200 and other devices.
[0038] Furthermore, please refer to Figures 1 to 4 , the PCB board 100 is provided with a connection hole 110. The key 200 includes a key body 210 and a tail pin 220. At least part of the tail pin 220 is located in the connection hole 110, and the tail pin 220 cooperates with the connection hole 110 to connect the key 200 and the PCB board 100.
[0039] In this embodiment, the tail pin 220 is disposed on the side of the key body 210 facing the PCB board 100, and the key 200 is disposed on the side surface 102. However, a connection needs to be made between the key 200 and the PCB board 100. If a part of the key 200 extends to the soldering surface 101 of the PCB board 100 and is connected to the PCB board 100 by means such as soldering, lapping, or clamping, this part of the key 200 will still occupy a certain area of the soldering surface 101.
[0040] In this embodiment, the connection holes 110 and the tail pins 220 are arranged to cooperate with each other, such that the tail pins 220 are located within the connection holes 110. Thus, this part of the tail pins 220 within the connection holes 110 does not need to occupy the area of the soldering surface 101, thereby achieving the effect of reducing the area of the soldering surface 101 and the volume of the key structure 10. It should be understood that the connection holes 110 can be arranged on the soldering surface 101 or the side surface 102.
[0041] Furthermore, please refer to Figures 2 to 4 , the tail pin 220 includes an arched portion 222 and a connecting portion 221, and the connecting portion 221 connects the arched portion 222 and the key body 210;
[0042] The arched portion 222 bends and arches towards the connection hole 110, and at least part of the arched portion 222 is located within the connection hole 110 and is connected to the inner wall of the connection hole 110.
[0043] In this embodiment, the arched portion 222 bending and arching towards the connecting portion 221 can increase the connection area between the tail pin 220 and the PCB board 100, thereby improving the structural stability of the PCB board 100 and the key 200, and further preventing the disconnection between the PCB board 100 and the key 200 due to bumping; at the same time, please refer to Figure 4 , for the key 200 of this embodiment, only the tail pins 220 need to be aligned with the connection holes 110 from bottom to top, and then the key 200 is moved so that multiple tail pins 220 are inserted into the corresponding connection holes 110, and the assembly of the key structure 10 can be achieved; if the tail pins 220 are serpentinely threaded through multiple connection holes 110, when installing the tail pins 220, it is necessary to control the tail pins 220 to pass through the connection holes 110 multiple times from top to bottom and from bottom to top, resulting in a lower assembly efficiency. Therefore, compared with the serpentine technical solution, the technical solution of this embodiment has a high assembly efficiency. In summary, the key structure 10 of this embodiment has strong structural stability and high assembly efficiency. It should be understood that the arched portion 222 can also increase the contact area between the tail pin 220 and the solder, thereby facilitating the solder to be inserted into the connection holes 110, and further improving the assembly efficiency of the key structure 10. The arched portion can be, for example, as Figure 4The U-shaped structure shown may also be a plurality of stacked U-shaped structures formed by continuously bending the tail feet 220. When the arched portion 222 is a plurality of stacked U-shaped structures formed by continuously bending the tail feet 220, the welding area of the arched portion 222 is larger, easier to assemble, and can effectively improve the assembly efficiency of the key structure 10.
[0044] Further, please refer to Figure 4 , one end of the arched portion 222 away from the connecting portion 221 is located within the connecting hole 110.
[0045] In this embodiment, if one end of the arched portion 222 away from the connecting portion 221 extends beyond the connecting hole 110, when the key structure 10 is assembled with other devices to form the medical device 20, one end of the arched portion 222 away from the connecting portion 221 may collide and be damaged with other devices, thereby causing the key 200 to malfunction. Therefore, the key structure 10 of this embodiment can avoid the malfunction of the key 200 of the medical device 20 composed of the key structure 10, thereby improving its service life.
[0046] Further, please refer to Figure 4 , the arched portion 222 and the connecting hole 110 are in clearance fit.
[0047] In this embodiment, due to the clearance fit between the arched portion 222 and the connecting hole 110, there is a certain space between the inner wall of the arched portion 222 and the connecting hole 110. This space can also prevent the arched portion 222 from colliding with the PCB board 100 when inserted into the connecting hole 110, thereby avoiding deformation of the arched portion 222 and being unable to be inserted or wear of the arched portion 222.
[0048] It should be understood that a guiding arc surface (not shown in the figure) may be provided on the surface of the connecting hole 110 facing the connecting portion 221. The guiding arc surface is located at the opening of the connecting hole 110. At this time, the guiding arc surface can further guide the arched portion 222 into the connecting hole 110, and can effectively prevent the arched portion 222 from colliding with the PCB board 100, thereby improving the assembly efficiency and yield of the key structure 10.
[0049] Further, please refer to Figures 1 to 4 , there are a plurality of connecting holes 110, arched portions 222 and connecting portions 221. The arched portions 222 and the connecting holes 110 correspond one by one, and two adjacent arched portions 222 are connected by a connecting portion 221.
[0050] In this embodiment, when there are multiple connecting holes 110, if the tail pin 220 is a continuous curve, the tail pin 220 needs to penetrate into the connecting hole 110 closest to the button body 210 from bottom to top, and then penetrate into the second connecting hole 110 from top to bottom. This assembly process requires high precision and is difficult to assemble. However, for the button structure 10 of this embodiment, only the tail pin 220 needs to be aligned with the connecting hole 110 from bottom to top, and then the button 200 is moved upward so that multiple arched portions 222 are inserted into the corresponding connecting holes 110, and the assembly of the button structure 10 can be achieved. Therefore, the assembly efficiency of the button structure 10 is high.
[0051] Further, please refer to Figures 1 to 4 , there are multiple buttons 200, and the multiple buttons 200 are symmetrically distributed on the side surface 102.
[0052] In this embodiment, the buttons 200 can be symmetrically distributed in the left-right direction of the PCB board 100. When the number of buttons 200 is an even number, the symmetrical distribution of the buttons 200 should be understood as: the buttons 200 are symmetrically distributed with respect to the symmetry axis in the left-right direction of the PCB board 100. At this time, for the button 200 on the left side of the PCB board 100, its tail pin 220 faces the left end of the PCB board 100, and for the button 200 on the right side of the symmetry axis, its tail pin 220 faces the right end of the PCB board 100. When the number of buttons 200 is an odd number, the symmetrical distribution of the buttons 200 should be understood as: for the button 200 on the symmetry axis of the PCB board 100, the direction of its tail pin 220 can face left or right, or can also face the middle. For the button 200 on the left side of the PCB board 100, its tail pin 220 faces the left end of the PCB board 100, and for the button 200 on the right side of the symmetry axis, its tail pin 220 faces the right end of the PCB board 100.
[0053] In summary, the symmetrical distribution of the button structure 10 in this embodiment can avoid uneven structural strength caused by too many connecting holes 110 being opened on one side of the PCB board 100.
[0054] Further, please refer to Figure 1 and Figure 2 , an installation groove 120 is provided on the side surface 102, at least part of the button body 210 is located in the installation groove 120, the connecting hole 110 is provided on the welding surface 101, and is located within the range formed by the edge of the welding surface 101 and the bottom of the installation groove 120.
[0055] In this embodiment, first, the button body 210 is located within the installation groove 120. Thus, the cooperation between the installation groove 120 and the button body 210 can prevent the button body 210 from shaking or shifting away from the preset position, thereby enhancing the structural strength of the button structure 10. Second, when assembling the button structure 10, the installation groove 120 can play a role in positioning the button body 210, thereby improving the assembly efficiency of the button structure 10. Finally, the connection hole 110 is located within the range formed by the edge of the welding surface 101 and the bottom of the installation groove 120, so as to avoid the connection hole 110 occupying the area near the center of the welding surface 101 and leaving installation positions for other components.
[0056] Further, please refer to Figures 1 to 4 , the button body 210 is a spring, and the tail pin 220 is provided at the end of the spring and lies in the same plane as the end of the spring.
[0057] In this embodiment, compared with the button body 210 being a mechanical button 200 or a touch screen button 200 and other structures, the button body 210 being a spring has a simple structure and low cost. At the same time, compared with the button body 210 being a shrapnel and other structures, when the button body 210 is a spring, the tail pin 220 can be directly formed by extending from the end of the spring. At this time, there is no need to add a step of connecting the tail pin 220 and the button body 210 during the production of the button 200, and its production cost is low. The tail pin 220 and the end of the spring being in the same plane can reduce the space occupancy rate of the spring in the up and down directions, and the button 200 can be stably placed flat on the horizontal plane, facilitating grasping.
[0058] Correspondingly, please refer to Figure 5 , this application also provides a medical device 20, and the medical device 20 includes the button structure 10 of any one of the above embodiments.
[0059] In this embodiment, since the medical device 20 includes the button structure 10 of any one of the above embodiments. Therefore, the setting of the button 200 will not increase the area of the welding surface 101. At the same time, the height of the button 200 will not affect the thickness of the button structure 10, so the button structure 10 is relatively thin. In summary, the medical device of this embodiment has a high space utilization rate and a small thickness.
[0060] Further, please refer to Figure 5 , in the figure, the Y direction is the front-back direction and the thickness direction, and the Z direction is the up-down direction. The medical device 20 includes a main body 300 and a support member 400. One side of the main body 300 is provided with a display surface 310, and the other side is provided with a support member 400. An angle is formed between the support member 400 and the main body 300 for supporting the main body 300. The display surface 310 is parallel to the welding surface 101. At this time, since the button 200 is located on its side rather than the display surface 310, the medical device has a flat structure, is relatively thin in thickness and small in volume, and is convenient to carry.
[0061] In this embodiment, the display surface 310 of the medical device 20 is generally used for displaying medical data, analysis charts, software operations, etc. Therefore, it may be necessary for the operator to touch the display surface 310. When the operator touches the display surface 310 in the front-back direction, the main body 300 may tip backward. At this time, the support member 400 serves to support the main body 300 and prevent the main body 300 from tipping over. If the medical device 20 does not require the operator to touch the display surface 310, the support member 400 can still support the main body 300, improve the strength of the main body 300, and prevent it from tipping over.
[0062] In summary, since the medical device 20 includes the key structure 10 in the above embodiment, and the display surface 310 is parallel to the welding surface 101, the keys 200 are located around the display surface 310 and intersect with the display surface 310. At this time, when the staff operates the keys 200, the main force direction of the medical device 20 is mainly the up-down direction, and the medical device 20 is not likely to tip over, thereby effectively improving the use efficiency of the medical device 20.
