In actual use, the accessories and the main unit often need to be frequently plugged and unplugged. The impact force generated during plugging and unplugging will directly affect the circuit board through the communication interface, resulting in a decrease in the connection stability of the circuit board.

One of the fixing component and the interface component has a support post on the side facing the first surface, and the other has a first connection hole on the side facing the second surface.

During the use of the electronic device, when the interface component is connected to or separated from an external connector, the impact force on the interface component is mainly transmitted to the fastener via the support post, and further transmitted to the housing of the electronic device. Since part or all of the circuit board is located within the installation gap, and the support post passes through the first hole, only a small amount of the impact force on the interface component is transmitted to the circuit board, or not at all; that is, the impact force on the circuit board can be significantly reduced or even avoided. Correspondingly, the electrical connection between the circuit board and the interface component has higher stability during use.

[0020] According to an embodiment of this application, an electronic device includes:

[0050] Many electronic devices typically include a main unit and accessories. Taking a patient monitor as an example, a monitor usually consists of a main unit and expansion modules. The main unit and expansion modules have matching communication interfaces, which are pluggable to each other, allowing data transmission during connection. In some electronic devices, a circuit board is soldered to the communication interface and secured to it with screws or other fasteners. When the communication interface is plugged in and out, the circuit board is directly subjected to the impact force generated during the process. Frequent plugging and unplugging can directly affect the soldering quality between the circuit board and the communication interface, reducing connection stability and, in severe cases, causing the solder joints to detach, thus affecting data transmission functionality.

[0051] This application provides an electronic device, comprising: a housing, a fixing member, and a communication interface fixing assembly. The fixing member is fixedly connected to the housing, or the fixing member and the housing are integrally formed. The communication interface fixing assembly includes an interface member and a circuit board; the interface member is fixedly connected to the fixing member, and the circuit board is electrically connected to the interface member. The interface member is provided with a communication interface, which can mate with the interface terminals of an external connector to transmit signals. Part or all of the circuit board is disposed between the interface member and the fixing member. The circuit board has a first surface and a second surface opposite to the first surface in the thickness direction, and a first hole penetrating the first and second surfaces is provided on the circuit board. One of the fixing member and the interface member has a support post on the side facing the first surface, and the other has a first connection hole on the side facing the second surface. The support post can mate with the first connection hole. When the support post mates with the first connection hole, there is an installation gap between the fixing member and the interface member, and part or all of the circuit board is located within the installation gap. The support post passes through the first hole. The interface member and the fixing member are fixedly connected at least through the mate of the support post and the first connection hole, so that when the external connector mates with the communication interface, part or all of the impact force is transferred from the interface member to the fixing member.

[0052] In at least one embodiment of the electronic device of this application, a fastener is fixedly connected to the housing of the electronic device, and an interface component is fixedly connected to the fastener at least through the cooperation of a support post and a first connection hole. Therefore, the interface component is fixed to the housing of the electronic device by the fastener. An installation gap exists between the interface component and the fastener for mounting a circuit board. During the use of the electronic device, when the interface component is connected to or separated from an external connector, the impact force on the interface component is mainly transmitted to the fastener via the support post, and further transmitted to the housing of the electronic device. Since part or all of the circuit board is located within the installation gap, and the support post passes through the first hole, only a small amount of the impact force on the interface component is transmitted to the circuit board, or not at all; that is, the impact force on the circuit board can be significantly reduced or even avoided. Correspondingly, the electrical connection between the circuit board and the interface component has higher stability during use.

[0053] Figure 1 This is a schematic diagram of the structure of an electronic device according to this application. (Refer to...) Figure 1 As shown, the electronic device includes a housing 200 and a communication interface fixing component 100. The communication interface fixing component 100 is connected to the housing 200, and a portion of the communication interface fixing component 100 protrudes from the housing 200 to facilitate the communication interface fixing component 100 to interface with other interfaces.

[0054] In some examples, the electronic device is a medical device. For instance, it is a patient monitor. A patient monitor is a device or system that measures and controls a patient's physiological parameters and compares them to known set values, issuing an alarm if any exceedances occur.

[0055] In some examples, the electronic device is a multi-parameter monitor. In other examples, the electronic device can be a portable monitor or a plug-in monitor. The portable monitor can be used independently or can communicate with expansion bases, expansion boxes, plug-in monitors, displays, and computers.

[0056] In some examples, the electronic device includes a monitor host, the housing 200 of which is the outer shell of the monitor host, and the communication interface fixing component 100 is disposed in and connected to the housing.

[0057] In a further example, the electronic device includes a monitor host and an expansion base. The expansion base is provided with a host communication interface adapted to the communication interface fixing component 100. The expansion base is used to mount the monitor host, which is detachably connected to the expansion base. When the monitor host is connected to the expansion base, the communication interface fixing component 100 on the monitor host mates with the host communication interface on the expansion base to communicate. Optionally, the expansion base is also provided with one or more expansion communication interfaces for connecting to expansion boxes, plug-in monitors, displays, computers, etc. When the monitor host is connected to the expansion base, the monitor host can communicate with external devices through the expansion communication interfaces on the expansion base.

[0058] In a further example, the expansion base includes a main unit slot and a parameter measurement slot. The main unit slot is for the detachable installation of the monitor's main unit, and the parameter measurement slot is for the detachable installation of the parameter measurement module. When the monitor's main unit and the parameter measurement module are mounted on the expansion base, the monitor's main unit can communicate with the parameter measurement module.

[0059] Figure 2 for Figure 1 A partial structural diagram of the electronic device is shown. This is to facilitate understanding of the connection relationship between the housing 200 and the communication interface fixing assembly 100. Figure 2 The diagram shows a portion of the housing 200, the fastener 300, and the communication interface mounting assembly 100 of the electronic device. (See reference...) Figure 2 As shown, in this embodiment, the communication interface fixing component 100 is connected to the housing 200 via a fixing member 300.

[0060] Figure 3 for Figure 2 A structural schematic diagram of the communication interface fixing component 100 and the fixing member 300. Figure 4 for Figure 3 A schematic diagram showing the disassembled structure of the communication interface fixing component 100 and the fixing piece 300. Figure 5 for Figure 3Another perspective of the split structure diagram of the communication interface fixing component 100 and the fixing member 300. (Refer to...) Figures 3-5 As shown, in this embodiment, the communication interface fixing component 100 includes an interface component 110 and a circuit board 120.

[0061] In this embodiment, the fastener 300 is fixedly connected to the housing 200 so that the communication interface fixing assembly 100 can be connected to the housing 200, and the position of the fastener 300 is fixed relative to the housing 200. (Refer to...) Figures 2-5 As shown, in some examples, the fastener 300 is fixedly connected to the housing 200 via a fixing connector 400. In a further example, the fastener 300 is provided with a fixing connection hole 304, the fixing connector 400 passes through the fixing connection hole 304, and the fixing connector 400 is fixedly connected to the housing 200, so that the fastener 300 is fixedly connected to the housing 200. The fixing connection hole 304 is a threaded hole, and the fixing connector 400 is a screw adapted to the threaded hole.

[0062] As can be understood, in this article, "penetration" refers to the first workpiece being inserted into and placed in the hole of the second workpiece. At this time, the hole on the second workpiece can be a through hole or a blind hole. The first workpiece can be inserted into part or all of the hole of the second workpiece, or it can pass through the hole of the second workpiece.

[0063] As examples, the material of the fastener 300 includes metal, for instance, the material of the fastener 300 is selected from one or more of aluminum, iron, copper, aluminum alloy, iron alloy, and copper alloy. The fastener 300, made of metal, is easy to process and has high hardness and strength, ensuring a secure connection between the communication interface fixing assembly 100 and the housing 200.

[0064] It is understood that in the above example, the fastener 300 is fixedly connected to the housing 200 via the fastener 400. However, in other examples, the fastener 300 and the housing 200 are an integral structure, or the fastener 300 and the housing 200 are integrally connected. In this case, the fastener 300 and the housing 200 can be integrally formed during the manufacturing process.

[0065] In this embodiment, the interface component 110 is fixedly connected to the fixing component 300, so that the position of the interface component 110 is fixed relative to the fixing component 300. The circuit board 120 is electrically connected to the interface component 110, so that the electrical signals of the interface component 110 are transmitted to the circuit board 120.

[0066] In some examples, the interface element 110 in the communication interface fixing assembly 100 protrudes from the housing 200 to facilitate interfacing with other interfaces. The interface element 110 may include a communication interface 111 that conforms to a certain communication protocol, which can interface with the interface of an external connector that conforms to the same communication protocol, thereby enabling data transmission between the two interfaces.

[0067] In some examples, the electronic device includes a monitor host and an expansion base. The monitor host is provided with a communication interface 111, and the expansion base is an external connector with an interface that works in conjunction with the communication interface 111.

[0068] In this embodiment, the circuit board 120 has a first surface and a second surface opposite to the first surface in the thickness direction. A first hole 123 is provided on the circuit board 120, penetrating both the first and second surfaces. One of the fixing member 300 and the interface member 110 has a support post 301 on the side facing the first surface, and the other has a first connection hole 113 on the side facing the second surface. The support post 301 can mate with the first connection hole 113. When the support post 301 mates with the first connection hole 113, there is an installation gap between the fixing member and the interface member. When the interface member 110 is subjected to an impact force, the force is first transmitted to the support post 301, and then to the fixing member 300 and the housing 200. Part or all of the circuit board 120 is located within the installation gap, and the support post 301 passes through the first hole 113.

[0069] In some examples, the support post 301 can mate with the first connecting hole 113. The support post 301 mates with the first connecting hole 113 in one of the following ways: (1) the support post 301 is located outside the first connecting hole 113 and is used to support the solid structure around the first connecting hole 113, so that there is an installation gap between the fastener 300 and the interface member 110. (2) the support post 301 is partially inserted into the first connecting hole 113 and supports part of the hole wall of the first connecting hole 113, so that there is an installation gap between the fastener 300 and the interface member 110.

[0070] Reference Figure 5 As shown, in some examples, the support post 301 is disposed on the fastener 300. The first connection hole 113 is disposed on the interface member 110. The interface member 110 and the fastener 300 are fixedly connected at least through the support post 301 and the first connection hole 113, so that when the external connector mates with the communication interface 111, part or all of the impact force is transferred from the interface member 110 to the fastener 300.

[0071] In some other embodiments, the support post 301 can also be disposed on the interface member 110, and the first connecting hole 113 can also be disposed on the fixing member 300, as long as the two can cooperate to make the interface member 110 and the fixing member 300 fixedly connected.

[0072] Reference Figures 3-5 As shown, in some examples, the fixing member 300 is provided with a receiving groove 302, the top opening 302a of the receiving groove 302 facing the interface member 110. A support post 301 is disposed in the receiving groove 302, and the end face of the support post 301 adjacent to the interface member 110 protrudes from the bottom wall of the receiving groove 302. The installation gap includes part or all of the receiving groove 302. Part or all of the circuit board 120 is located in the receiving groove 302. It can be understood that the receiving groove 302 can provide a certain installation gap for part or all of the circuit board 120, which is beneficial for limiting the position of the circuit board 120 and ensuring a relatively stable electrical connection between the circuit board 120 and the interface member 110. At the same time, the support post 301 protruding from the bottom wall of the groove can limit the distance between the interface member 110 and the bottom wall of the receiving groove 302, which allows the circuit board 120 to be protected by the fixing member 300, which helps to reduce external impacts on the circuit board 120 and further improves the connection stability of the circuit board 120.

[0073] In a further example, the portion of the support column 301 protruding from the bottom wall of the receiving groove 302 is columnar. For example, the portion of the support column 301 protruding from the bottom wall of the receiving groove 302 is cylindrical, or it is prismatic, or it is an irregular columnar shape.

[0074] In some examples, the support post 301 is in direct contact with the interface component 110.

[0075] In a further example, the end face of the support post 301 adjacent to the interface member 110 is flush with the top opening 302a of the receiving groove 302, or the end face of the support post 301 adjacent to the interface member 110 is lower than the top opening 302a of the receiving groove 302. By setting the end face of the support post 301 to be flush with or lower than the top opening 302a of the receiving groove 302, the interface member 110 can be used to block part or all of the top opening 302a, thus partially or completely blocking the receiving groove 302, which provides a more sufficient limiting effect for the circuit board 120.

[0076] Reference Figures 3-5 As shown, in some examples, the communication interface fixing assembly 100 includes a connector 150, and the fixing member 300 and the interface member 110 are fixedly connected by the connector 150.

[0077] In a further example, the interface component 110 is provided with a first connecting hole 113, and the fixing component 300 is provided with a second connecting hole 303 opening into the support post 301. The connector 150 passes through the first connecting hole 113 and the second connecting hole 303 to fix the fixing component 300 and the interface component 110. It can be understood that since the opening of the second connecting hole 303 is located on the support post 301, the first hole 123 on the circuit board 120 also surrounds the connector 150. Therefore, the connector 150 can not only fix the fixing component 300 and the interface component 110, but also restrict the lateral displacement of the circuit board 120, avoiding the problem of unstable electrical connection caused by the lateral displacement of the circuit board 120.

[0078] In other examples, the fastener 300 can also be fixedly connected to the interface component 110 by means of adhesion, clamping, or welding. Compared to connection methods such as adhesion or clamping, the connector 150, which passes through the second connection hole 303, is more advantageous for limiting the lateral displacement of the circuit board 120.

[0079] In a further example, the second connecting hole 303 penetrates the fastener 300, and one opening of the second connecting hole 303 is located on the end face of the support post 301 near the interface member 110, while the other opening of the second connecting hole 303 is located on the surface of the fastener 300 opposite to the interface member 110.

[0080] In a further example, the first connecting hole 113 is a threaded hole, the connector 150 is a screw adapted to the threaded hole, and the connector 150 passes through the second connecting hole 303 and into the first connecting hole 113 to achieve a fixed connection between the fastener 300 and the interface 110.

[0081] In some examples, the first connection hole 113 and the second connection hole 303 are connected.

[0082] In a further example, the interface member 110 is provided with a plurality of first connecting holes 113. Correspondingly, the fixing member 300 is provided with the same number of second connecting holes 303 as the first connecting holes 113, and the number of connectors 150 is the same as the number of second connecting holes 303, with each connector 150 passing through both the first connecting holes 113 and the second connecting holes 303. Providing multiple first connecting holes 113, second connecting holes 303, and connectors 150 improves the connection stability between the fixing member 300 and the connectors 150. Furthermore, the number of first connecting holes 113 is two. The multiple first connecting holes 113 are arranged side-by-side along the same direction.

[0083] In this embodiment, the circuit board 120 is used not only for electrically connecting the interface device 110, but also for electrically connecting to the motherboard of the electronic device to realize signal transmission between the interface device 110 and the motherboard.

[0084] Reference Figures 3-5 As shown, in some examples, the circuit board 120 includes an interface connection board 121 and a motherboard connection board 122 connected together. The interface connection board 121 is electrically connected to the interface component 110, and the motherboard connection board 122 is used for electrical connection to the motherboard of the electronic device. The interface connection board 121 is disposed in a receiving groove 302. The receiving groove 302 also has a side opening disposed on the side wall of the groove, through which the motherboard connection board 122 passes, and a portion of the motherboard connection board 122 extends outside the receiving groove 302. The interface connection board 121 is disposed in the receiving groove 302, thereby limiting the entire circuit board 120 by the receiving groove 302. The motherboard connection board 122 is connected to the interface connection board 121 and extends outside the receiving groove 302, thus enabling electrical connection to the motherboard of the electronic device. This structural design cleverly incorporates a side opening on the side wall of the receiving groove 302, achieving both limiting the circuit board 120 and not affecting the electrical connection between the circuit board 120 and the motherboard.

[0085] Reference Figures 3-5 As shown, the motherboard connector board 122 is provided with a motherboard interface 160 for electrical connection with the motherboard.

[0086] Reference Figures 3-5 As shown, the communication interface fixing assembly 100 also includes a reinforcement plate 170. The reinforcement plate 170 is disposed on the side of the motherboard connection plate 122 opposite to the motherboard interface 160. The reinforcement plate 170 is used to suppress the deformation of the circuit board 120 at the motherboard interface 160, which is beneficial to the stable connection between the motherboard interface 160 and the motherboard.

[0087] If the circuit board 120 is directly fixed to the interface component 110, a printed circuit board 120 (PCB) is usually required. The printed circuit board 120 is made of a relatively rigid material and is suitable for independent connection to the interface component 110.

[0088] This application found in its research that, in this embodiment, since the interface component 110 is connected to the fixing component 300, and the circuit board 120 is confined between the interface component 110 and the fixing component 300, the circuit board 120 can still be stably positioned even if it is formed of a softer material. In some examples, the circuit board 120 is a flexible printed circuit board (FPC). The material cost of the flexible printed circuit board 120 is significantly lower than that of the printed circuit board 120. Therefore, using a flexible printed circuit board 120 as the circuit board 120 in this embodiment can significantly reduce the material cost of the communication interface fixing component 100 while ensuring the stable positioning of the circuit board 120.

[0089] In some examples, the circuit board 120 is soldered to the interface component 110. In a further example, the surface of the circuit board 120 facing the interface component 110 is provided with circuit contacts, and the surface of the interface component 110 facing the circuit board 120 is provided with interface contacts for soldering to the circuit contacts. The circuit contacts and the interface contacts are soldered together by means of surface mounting, thereby realizing the electrical connection between the circuit board 120 and the interface component 110.

[0090] Reference Figures 3-5 As shown, in some examples, the communication interface fixing assembly 100 includes a reinforcing plate 130. The Young's modulus of the reinforcing plate 130 is greater than that of the circuit board 120, meaning that the reinforcing plate 130 is less prone to deformation than the circuit board 120. The reinforcing plate 130 is disposed on the side of the circuit board 120 facing away from the interface component 110. A second hole 131 is provided on the reinforcing plate 130, which surrounds the support post 301. The reinforcing plate 130 is used to suppress the deformation of the circuit board 120, ensuring that the circuit board 120 has a relatively stable shape during assembly and use. It can be understood that the second hole 131 on the reinforcing plate 130 surrounds the support post 301, so the reinforcing plate 130 can be confined together with the circuit board 120 between the interface component 110 and the fixing component 300.

[0091] In a further example, the reinforcing plate 130 overlaps with part or all of the circuit board 120. For example, the reinforcing plate 130 overlaps with the interface connection plate 121 of the circuit board 120.

[0092] In a further example, the reinforcing plate 130 is disposed in the receiving groove 302 of the fastener 300.

[0093] In a further example, the reinforcing plate 130 is adhered to the side of the circuit board 120 away from the interface member 110.

[0094] In a further example, the reinforcing plate 130 may be made of, but is not limited to, metal and plastic. For example, polyethylene terephthalate (PET) may be used as the material of the reinforcing plate 130.

[0095] Reference Figures 3-5 As shown, the communication interface fixing assembly 100 includes a buffer pad 140. The buffer pad 140 is disposed between the circuit board 120 and the fixing member 300. A third hole 141 is provided through the buffer pad 140, surrounding the support post 301. The buffer pad 140 serves two purposes: firstly, it limits the position of the circuit board 120, ensuring the structural stability of the circuit board 120; secondly, it prevents direct contact between the circuit board 120 and the fixing member 300, thus protecting the circuit board 120.

[0096] As a further example, the cushioning pad 140 is made of a polymer material, which is easily deformable and has good cushioning properties. For example, the cushioning pad 140 could be a silicone pad.

[0097] As a further example, some or all of the buffer pads 140 are disposed in the receiving groove 302, and the buffer pads 140 fill the space between the circuit board 120 and the bottom wall of the receiving groove 302. The buffer pads 140 filled in the receiving groove 302 can also prevent water and oxygen from penetrating into the circuit board 120, thus inhibiting the aging of the circuit board 120 and improving the service life of the circuit board 120.

[0098] As a further example, the cushioning pad 140 overlaps with part or all of the circuit board 120. For example, the cushioning pad 140 overlaps with the interface connection plate 121 of the circuit board 120.

[0099] As examples, the dimension of the mounting gap in the thickness direction of the circuit board 120 is greater than the sum of the thickness of the circuit board 120 and the thickness of the reinforcing plate 130, and the dimension of the mounting gap in the thickness direction of the circuit board 120 is less than the sum of the thickness of the circuit board 120, the thickness of the reinforcing plate 130 and the thickness of the buffer pad 140.

[0100] Reference Figures 3-5 As shown, in some examples, the interface component 110 has a positioning post 112 on the side facing the fixing component 300. The positioning post 112 passes through the first hole 123, and the top end of the positioning post 112 is located in the third hole 141. The positioning post 112 is used to position the circuit board 120 and the buffer pad 140 when they are installed. By fitting the first hole 123 of the circuit board 120 and the third hole 141 of the buffer pad 140 onto the positioning post 112, both the circuit board 120 and the buffer pad 140 can be aligned with the interface component 110. At the same time, placing the top end of the positioning post 112 in the third hole 141 also avoids contact between the positioning post 112 and the fixing component 300.

[0101] Reference Figures 3-5 As shown, in some examples, one or more positioning posts 112 are provided on one side of each support post 301. In this example, one positioning post 112 is provided on one side of a support post 301. The support post 301 and the positioning post 112 can work together to limit the movement.

[0102] Figure 6 This is a top view schematic diagram of a circuit board 120. (Refer to...) Figure 6 As shown, the circuit board 120 has a first hole 123. In some examples, the first hole 123 includes a first support area 123a and a first positioning area 123b. Combined with... Figures 3-6 As shown, the first support area 123a surrounds the support post 301, and the positioning post 112 passes through the first positioning area 123b. The first positioning area 123b is connected to the first support area 123a, and the first positioning area 123b is located on one side of the first support area 123a. In this example, the positioning post 112 and the support post 301 can jointly limit the circuit board 120.

[0103] Figure 7 This is a top view schematic diagram of a cushioning pad 140. (Refer to...) Figure 7 As shown, the cushioning pad 140 is provided with a third hole 141. In some examples, the third hole 141 includes a third support area 141a and two third positioning areas 141b. The third support area 141a surrounds the support post 301, and the top of the positioning post 112 is located in one of the third positioning areas 141b. In this example, the positioning post 112 and the support post 301 can jointly limit the position of the cushioning pad 140.

[0104] In a further example, both third positioning areas 141b are connected to the third support area 141a, and the third support area 141a is positioned between the two third positioning areas 141b, with the two third positioning areas 141b arranged in a mirror-symmetric manner. By providing two mirror-symmetrically arranged third positioning areas 141b on the buffer pad 140, either third positioning area 141b can be fitted onto the positioning post 112. Therefore, during installation, the buffer pad 140 can be placed along two mirror-symmetric lines, which helps reduce the installation difficulty of the buffer pad 140 and simplifies the installation process.

[0105] Figure 8 This is a top view schematic diagram of a reinforcing plate 130. (Refer to...) Figure 8 As shown, the reinforcing plate 130 has a second hole 131. In some examples, the second hole 131 includes a second support area 131a and a second positioning area 131b. (Combined with...) Figures 3-8 As shown, the second support area 131a surrounds the support column 301, and the positioning column 112 passes through the second positioning area 131b. The second positioning area 131b is connected to the second support area 131a, and is located on one side of the second support area 131a. In this example, the positioning column 112 and the support column 301 can jointly limit the position of the reinforcing plate 130.

[0106] In some examples, the second hole 131 overlaps with the first hole 123, and the third hole 141 covers the first hole 123 and the second hole 131.

[0107] In some examples, the first hole 123, the second hole 131, and the third hole 141 are all located above the first connecting hole 113. The cross-section of the first support region 123a in the first hole 123 is larger than the cross-section of the first connecting hole 113. The cross-section of the second support region 131a in the second hole 131 is larger than the cross-section of the first connecting hole 113. The cross-section of the third support region 141a in the third hole 141 is larger than the cross-section of the first connecting hole 113.

[0108] In some examples, the first hole 123, the second hole 131, and the third hole 141 are all arranged around the support post 301.

[0109] In a further example, the cross-section of the first support region 123a in the first hole 123 is larger than the cross-section of the support column 301, so that the support column 301 can pass through the first support region 123a during installation. Similarly, the cross-section of the second support region 131a in the second hole 131 is larger than the cross-section of the support column 301, so that the support column 301 can pass through the second support region 131a during installation. Likewise, the cross-section of the third support region 141a in the third hole 141 is larger than the cross-section of the support column 301, so that the support column 301 can pass through the third support region 141a during installation.

[0110] In some examples, the wall of the first hole 123 is spaced apart from or partially in contact with the support post 301. Further, the circuit board 120 is spaced apart from or partially in contact with the support post 301. The wall of the second hole 131 is spaced apart from or partially in contact with the support post 301. Further, the reinforcing plate 130 is spaced apart from or partially in contact with the support post 301. The wall of the third hole 141 is spaced apart from or partially in contact with the support post 301. Further, the buffer pad 140 is spaced apart from or partially in contact with the support post 301.

[0111] The electronic device in the embodiments of this application can be a patient monitor, such as a portable patient monitor.

[0112] Since the circuit board 120 in the electronic device used in this application embodiment only requires a small impact force or does not need to withstand an impact force, the use of a flexible circuit board 120 instead of a printed circuit board 120 can significantly reduce the cost of the circuit board 120 while ensuring the connection stability of the circuit board 120.

[0113] The additional reinforcing plate 130 provided in this embodiment can suppress the deformation of the flexible circuit board 120 during assembly and use, ensuring that the circuit board 120 has a stable shape.

[0114] The additional buffer pad 140 provided in this embodiment can not only limit the circuit board 120, but also prevent direct contact between the circuit board 120 and the fixing member 300, thus protecting the circuit board 120.

[0115] Another embodiment of this application provides an electronic device, comprising: a housing, a fixing member, and a communication interface fixing assembly. The fixing member is fixedly connected to the housing, or the fixing member and the housing are an integral structure. The communication interface fixing assembly includes an interface component and a circuit board; the interface component is fixedly connected to the fixing member, the circuit board is electrically connected to the interface component, and the interface component is provided with a communication interface capable of cooperating with the interface terminals of an external connector to transmit signals.

[0116] In this design, some or all of the circuit boards are disposed between the interface component and the fixing component. The circuit board has a first surface and a second surface opposite to the first surface in the thickness direction. One of the fixing component and the interface component has a first mating part on the side facing the first surface, and the other has a second mating part on the side facing the second surface. The first mating part can mate with the second mating part. When the first mating part and the second mating part mate, there is an installation gap between the fixing component and the interface component, and some or all of the circuit board is located within the installation gap. The interface component and the fixing component are fixedly connected at least through the contact mating of the first mating part and the second mating part. The circuit board has a first hole penetrating through the first surface and the second surface, and the entire assembly of the first mating part and the second mating part passes through the first hole.

[0117] In this embodiment of the electronic device, the fastener is fixedly connected to the housing of the electronic device, and the interface component and the fastener are fixedly connected through at least a first mating part and a second mating part. Therefore, the interface component is fixed to the housing of the electronic device by the fastener. A mounting gap exists between the interface component and the fastener for the circuit board. During the use of the electronic device, when the interface component is connected to or separated from an external connector, the impact force on the interface component is mainly transmitted to the fastener via the first and second mating parts, and further transmitted to the housing of the electronic device. Part or all of the circuit board is located within the mounting gap, and the entire assembly of the first and second mating parts passes through the first hole. Therefore, only a small amount of the impact force on the interface component is transmitted to the circuit board, or not at all; that is, the impact force on the circuit board can be significantly reduced or even avoided. Correspondingly, the electrical connection between the circuit board and the interface component has higher stability during use.

[0118] The first and second mating parts are connected by contact to fix the fastener and the interface. In some examples, the mating method of the first and second mating parts is selected from the following: (1) the first and second mating parts are connected by a mortise and tenon structure; (2) the first and second mating parts are snapped together; (3) the first and second mating parts are engaged; (4) the first and second mating parts are snapped together; (5) the first and second mating parts are bonded together.

[0119] In some examples, the fastener is provided with a receiving groove with the top opening facing the interface member, the first mating part is provided in the receiving groove, and the top of the first mating part protrudes from the bottom wall of the receiving groove. The installation gap includes part or all of the receiving groove, and part or all of the circuit board is located in the receiving groove.

[0120] In some examples, the communication interface fixing component includes a reinforcing plate with a Young's modulus greater than that of the circuit board. The reinforcing plate is disposed on the side of the circuit board opposite to the interface component. The reinforcing plate has a second hole that penetrates through the reinforcing plate along the thickness direction. The first mating part and the second mating part are fitted together and pass through the second hole.

[0121] In some examples, the communication interface fixing component includes a buffer pad disposed between the circuit board and the fixing member. The buffer pad has a third hole that penetrates through the buffer pad in the thickness direction, and the first mating part and the second mating part are fitted together and pass through the third hole.

[0122] In some examples, the mounting gap in the thickness direction of the circuit board is greater than the sum of the thickness of the circuit board and the thickness of the reinforcing plate, while the mounting gap in the thickness direction of the circuit board is less than the sum of the thickness of the circuit board, the thickness of the reinforcing plate, and the thickness of the cushioning pad.

[0123] In some examples, the wall of the first hole is either entirely spaced or partially in contact with the first and second mating parts after mating. Further, the circuit board is either entirely spaced or partially in contact with the first and second mating parts after mating. The wall of the second hole is either entirely spaced or partially in contact with the first and second mating parts after mating. Further, the reinforcing plate is either entirely spaced or partially in contact with the first and second mating parts after mating. The wall of the third hole is either entirely spaced or partially in contact with the first and second mating parts after mating. Further, the buffer pad is either entirely spaced or partially in contact with the first and second mating parts after mating.

[0124] In some examples, the circuit board is a flexible circuit board.

[0125] In some examples, the electronic device is a patient monitor. In further examples, the electronic device is a portable patient monitor.

[0126] It is understood that the main difference between this embodiment and the previous embodiment is that a first mating part and a second mating part are provided in this embodiment. The structural design of other components in this embodiment can refer to the structural design of the corresponding components in the previous embodiment, and will not be described again here.

[0127] 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.
