Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0037] Please refer to Figure 1 The utility model embodiment provides an ECG device, including ECG module 1 to be installed on the metal plate, shield cover 2, first insulating piece, first conductive piece, second insulating piece 3 and third insulating piece 4, ECG module 1 is installed on the metal plate, and ECG module 1 includes application part and input part, first insulating piece is equipped in application part, is used for realizing the insulating connection between application part and metal plate;First conductive piece is equipped in input part, is used for realizing the ground connection between input part and metal plate;Shield cover 2 is covered and is equipped in the outside of ECG module 1;Second insulating piece 3 is equipped between ECG module 1 and metal plate;Third insulating piece 4 is equipped between shield cover 2 and ECG module 1.

[0038] It can be understood that when the ECG device is installed on the metal plate of the portable ultrasound equipment shell as a separate part on the circuit board of the portable ultrasound equipment, the application part of the ECG module 1 is provided with a first insulating piece for insulating connection with the metal plate to realize floating ground of the application part, and a second insulating piece 3 is arranged between the ECG module 1 and the metal plate, and a third insulating piece 4 is arranged between the ECG module 1 and the shielding cover 2. The first insulating piece, the second insulating piece 3 and the third insulating piece 4 jointly act to increase the creepage distance of the ECG module 1 in each direction, thereby improving the voltage resistance of the application part of the ECG module 1, so that the application part of the ECG module 1 can meet the voltage resistance requirement, for example, to meet the 4kV voltage resistance design requirement. The input part of the ECG module 1 is provided with a first conductive piece for conductive connection with the metal plate to realize grounding of the input part. In addition, the shielding cover 2 is arranged outside the ECG module 1, which plays a role of electromagnetic shielding to prevent electromagnetic interference between other circuit modules on the integrated circuit board and the ECG module 1.

[0039] Therefore, compared with the related art in which the ECG module 1 is integrated with other modules, the ECG device can realize the independence of the ECG module 1, so that it becomes an independent module on the circuit board to realize detachable installation, facilitating maintenance and reducing maintenance cost.

[0040] It should be noted that the application part and the input part of the ECG module 1 are not limited in terms of their respective setting modes and functions, for example, the application part has a preset voltage resistance (such as 4kV voltage resistance) and a requirement for preventing electromagnetic interference, and needs to be designed for floating ground and shielding. The input part has a grounding requirement, and the specific details can be referred to in the related art.

[0041] It should be noted that the specific structure and setting mode of the first insulating piece and the first conductive piece are not limited, as long as they can realize the insulating connection between the application part and the metal plate and the grounding connection between the input part and the metal plate.

[0042] Please refer to Figure 1In some embodiments, the first insulating member comprises a first insulating fastener 6, and the first conductive member comprises a first conductive fastener 7; the first insulating fastener 6 and the first conductive fastener 7 are respectively detachably connected to the metal plate after penetrating the thickness of the circuit board of the ECG module 1. That is, the circuit board of the ECG module 1 is respectively provided with a first mounting hole and a second mounting hole corresponding to the application part and the input part, the first insulating fastener 6 is detachably connected to the metal plate after penetrating the first mounting hole, and the first conductive fastener 7 is detachably connected to the metal plate after penetrating the second mounting hole, so as to realize the insulating connection between the application part and the metal plate and the grounding connection between the input part and the metal plate. The structure is simple and convenient to connect.

[0043] In some embodiments, the first insulating fastener 6 is a first stud, the metal plate is provided with a first positioning column, the first positioning column is provided with a first threaded hole, and the first insulating fastener 6 is connected to the first positioning column through the threaded connection of the first stud and the first threaded hole, that is, the first insulating fastener 6 is connected to the metal plate. Of course, the first insulating fastener 6 and the first positioning column can also be connected and fixed through interference fit.

[0044] In some embodiments, the first conductive fastener 7 is a second stud, the metal plate is provided with a second positioning column, the second positioning column is provided with a second threaded hole, and the first conductive fastener 7 is connected to the second positioning column through the threaded connection of the second stud and the second threaded hole, that is, the first conductive fastener 7 is connected to the metal plate. Of course, the first conductive fastener 7 and the second positioning column can also be connected and fixed through interference fit.

[0045] In other embodiments, the first insulating fastener 6 can also be fixed to the metal plate through an adhesive after penetrating the thickness of the circuit board of the ECG module 1.

[0046] In addition, the specific material of the first insulating fastener 6 and the first conductive fastener 7 is not limited in the embodiment, for example, the first insulating fastener 6 can be a plastic part, and the first conductive fastener 7 is a metal part.

[0047] In addition, the number and distribution of the first insulating fastener 6 and the first conductive fastener 7 are not limited in the embodiment. Considering the reliability of the connection between the first insulating fastener 6 and the metal plate, in some embodiments, the number of the first insulating fastener 6 is at least two, for example, the number of the first insulating fastener 6 is three, and the three first insulating fasteners 6 are arranged non-collinearly. In some embodiments, the number of the first conductive fastener 7 is one, as long as it can realize the grounding connection between the input part and the metal plate. In this way, the ECG module 1 is installed on the metal plate through the cooperation of the first insulating fastener 6 and the first conductive fastener 7, and the reliable connection between the ECG module 1 and the metal plate is realized.

[0048] Further, please continue to refer to Figure 1 In order to facilitate the connection of the shield 2 and the ECG module 1, in some embodiments, the ECG device further comprises a second insulating fastener 8, which is connected with the first insulating fastener 6 after penetrating the shield 2 and the third insulating piece 4. It can be understood that the part of the shield 2 corresponding to the first insulating fastener 6 is provided with a third mounting hole, and the part of the third insulating piece 4 corresponding to the first insulating fastener 6 is provided with a third through hole. When installing, the second insulating fastener 8 is sequentially penetrated from the third mounting hole and the third through hole, and the second insulating fastener 8 is connected with the first insulating fastener 6, so that the connection of the shield 2 and the ECG module 1 can be realized. It can be understood that the second insulating fastener 8 needs to have insulation to insulate the application part from the shield 2. It should be noted that the specific structure of the second insulating fastener 8 and the connection mode thereof with the first insulating fastener 6 are not limited in the embodiment, as long as the connection of the two can be realized. In some embodiments, the second insulating fastener 8 is a first screw, and the first insulating fastener 6 is provided with a third threaded hole. The connection of the second insulating fastener 8 and the first insulating fastener 6 is realized by threaded connection of the first screw and the third threaded hole. Of course, the connection and fixation of the two can also be realized by interference fit of the second insulating fastener 8 and the first insulating fastener 6. In addition, the specific material of the second insulating fastener 8 is not limited in the embodiment. For example, the second insulating fastener 8 can be a plastic part.

[0049] In addition, it should be noted that the specific number of the second insulating fastener 8 is not limited in the embodiment. The number and distribution of the second insulating fastener 8 can be the same as that of the first insulating fastener 6, or the number of the second insulating fastener 8 can be less than that of the first insulating fastener 6. For example, in some embodiments, the number of the first insulating fastener 6 is three, and the number of the second insulating fastener 8 is two. It can be understood that the more the number of the first insulating fastener 6, the more the fixing points, the more reliable the fixation of the ECG module 1, and the less likely the position of the ECG module 1 to change and deform after being fixed. Compared with the installation of the ECG module 1, the installation requirement of the shield 2 is lower, so that the number of the second insulating fastener 8 is less than that of the first insulating fastener 6, as long as the installation of the shield 2 can be realized. The smaller number of the second insulating fastener 8 can simplify the installation process and improve the assembly efficiency.

[0050] In addition, please continue to refer to Figure 1To facilitate the ground connection between the ECG module 1 and the shielding cover 2, in some embodiments, the ECG device further includes a second conductive fastener 9, which passes through the shielding cover 2 and the third insulating member 4 and then connects to the first conductive fastener 7. It is understood that the portion of the shielding cover 2 corresponding to the first conductive fastener 7 is provided with a fourth mounting hole, and the portion of the third insulating member 4 corresponding to the first conductive fastener 7 is provided with a fourth through-hole. During installation, the second conductive fastener 9 is passed through the fourth mounting hole and the fourth through-hole in sequence, and the second conductive fastener 9 is connected to the first conductive fastener 7 to achieve the connection between the shielding cover 2 and the ECG module 1. It is understood that the second conductive fastener 9 needs to be conductive to achieve the ground connection between the shielding cover 2 and the ECG module 1. It should be noted that this embodiment does not limit the specific structure of the second conductive fastener 9 and its connection method with the first conductive fastener 7, as long as the connection between the two can be achieved. In some embodiments, the second conductive fastener 9 is a second screw, and the first conductive fastener 7 is provided with a fourth threaded hole. The second conductive fastener 9 is connected to the first conductive fastener 7 through the threaded connection between the second screw and the fourth threaded hole. Of course, the second conductive fastener 9 can also be connected and fixed by interference fit with the first conductive fastener 7. In addition, this embodiment does not limit the specific material of the second conductive fastener 9. For example, the second conductive fastener 9 is a metal piece.

[0051] In addition, the above embodiment does not limit the specific structure of the second insulating member 3 , as long as it can provide insulation between the ECG module 1 and the metal plate.

[0052] Please continue to refer to Figure 1In some embodiments, the second insulating member 3 is a box-shaped structure with an open top, the ECG module 1 is arranged inside the second insulating member 3, and the bottom of the second insulating member 3 is arranged on the metal plate. That is, in the present embodiment, the second insulating member 3 is designed as a box-shaped structure, so that the ECG module 1 arranged inside the second insulating member 3 is well insulated from the metal plate. In some embodiments, the four corners of the box-shaped second insulating member 3 are overlapped and bonded by an adhesive (in some embodiments, the adhesive is an insulating pressure-resistant adhesive, such as acrylic Yamin adhesive), so as to improve the sealing performance of the four corners of the box-shaped second insulating member 3 and avoid the occurrence of gaps at the four corners of the box-shaped second insulating member 3. In addition, the present embodiment does not limit the connection mode of the bottom of the second insulating member 3 and the metal plate. In some embodiments, the bottom of the second insulating member 3 is provided with a back adhesive, for example, the bottom of the second insulating member 3 is covered with a layer of 3M adhesive. That is, in the present embodiment, the bottom of the second insulating member 3 is bonded to the metal plate by the back adhesive, and the installation mode is simple and convenient. In addition, it can be understood that the second insulating member 3 is provided with a first through hole for the first positioning column on the metal plate to pass through, so as to be positioned and connected with the first insulating fastener 6 through the first positioning column, and realize the connection between the application part of the ECG module 1 and the metal plate. Similarly, the second insulating member 3 is provided with a second through hole for the second positioning column to pass through, so as to be positioned and connected with the first conductive fastener 7 through the second positioning column, and realize the grounding connection between the input part of the ECG module 1 and the metal plate.

[0053] Of course, in other embodiments, the second insulating member 3 can also be a rubber coating arranged on the metal plate. That is, by designing the metal plate to be rubber-coated, the ECG module 1 is insulated from the metal plate, and a separate second insulating member 3 is not used.

[0054] In addition, the above embodiments do not limit the specific structure of the third insulating member 4, as long as it can play the role of insulation between the ECG module 1 and the shielding cover 2. Please continue to refer to Figure 1 In some embodiments, the third insulating member 4 and the shielding cover 2 are both box-shaped structures with open bottoms, the third insulating member 4 is nested inside the shielding cover 2 and outside the second insulating member 3. That is, in the present embodiment, the third insulating member 4 and the shielding cover 2 are designed as box-shaped structures, so that the shielding cover 2 plays a better shielding role, and the ECG module 1 is well insulated from the shielding cover 2. In addition, the third insulating member 4 is nested with the second insulating member 3, so that the periphery of the third insulating member 4 coincides with that of the second insulating member 3, and has two layers of insulating materials. Therefore, it is beneficial to improve the insulation between the ECG module 1 and the shielding cover 2, so as to solve the problem of insufficient creepage distance between the application part of the ECG module 1 and the surrounding metal of the shielding cover 2, and improve the insulation pressure resistance of the application part.

[0055] In some embodiments, the third insulation member 4 of the box-shaped structure is overlapped at the four corners and is bonded by an adhesive to improve the sealing of the third insulation member 4 of the box-shaped structure and avoid gaps at the four corners of the third insulation member 4 of the box-shaped structure. In some embodiments, the adhesive is an insulation pressure-resistant glue, such as acrylic epoxy glue.

[0056] In other embodiments, the third insulation member 4 can be encapsulated on the shielding cover 2, that is, the shielding cover 2 is designed to be encapsulated to achieve insulation shielding without using a separate third insulation member 4.

[0057] It should be noted that the above embodiments do not limit the specific structure of the shielding cover 2. In some embodiments, the shielding cover 2 is a box-shaped structure with an open bottom, and the four corners of the shielding cover 2 are overlapped to achieve good shielding of the ECG module 1.

[0058] In addition, the specific material of the shielding cover 2 is not limited in the above embodiments, as long as it can play a shielding role. For example, the shielding cover 2 can be a metal shielding cover 2, a 304 stainless steel shielding cover 2, or a tinplate shielding cover 2. In some embodiments, the shielding cover 2 is a shielding cover 2 made of white copper, which can well balance the electric and magnetic shielding functions.

[0059] In addition, the specific materials of the second insulation member 3 and the third insulation member 4 are not limited in the above embodiments, as long as they can play an insulation role. In some embodiments, the second insulation member 3 and the third insulation member 4 can be made of PC, PET, PP, or PVC, respectively.

[0060] Please refer to Figure 1 and Figure 2 In some embodiments, the shielding cover 2 and the third insulation member 4 at the positions corresponding to the application part are respectively provided with a first ECG external connecting line via hole 21 and a second ECG external connecting line via hole 41 through which the connecting line of the application part passes, and the radial dimension of the second ECG external connecting line via hole 41 is smaller than that of the first ECG external connecting line via hole 21. That is, the connecting line of the application part of the ECG module 1 can pass through the second ECG external connecting line via hole 41 and the first ECG external connecting line via hole 21 in sequence to realize the connection of the ECG module 1 with other modules. The radial dimension of the second ECG external connecting line via hole 41 is smaller than that of the first ECG external connecting line via hole 21, that is, the second ECG external connecting line via hole 41 is smaller than the first ECG external connecting line via hole 21, which can avoid the problem of insufficient creepage distance caused by the third insulation member 4 having an excessively large opening.

[0061] In addition, please continue to refer to Figure 1 and Figure 2In some embodiments, the shielding cover 2 and the third insulating member 4 are provided with vias at positions corresponding to the input portion for the output connection wires to pass through. For example, the shielding cover 2 is provided with a first connection wire via 22, and the third insulating member 4 is provided with a second connection wire via 42. The connection wires pass through the second connection wire via 42 and the first connection wire via 22 in sequence, thereby connecting the ECG module 1 to the preset circuit board, thereby achieving power supply and communication between the ECG module 1 and the preset circuit board.

[0062] In addition to the aforementioned ECG device, the present invention further provides a portable ultrasound device including the ECG device disclosed in the aforementioned embodiments. The housing of the portable ultrasound device comprises a metal plate, and the ECG device is mounted on the metal plate of the portable ultrasound device. The structures of the other components of the portable ultrasound device are described in detail in the prior art and will not be further described herein.

[0063] The key point of this embodiment is that the ECG device disclosed in any of the above embodiments has the same beneficial effects as the above ECG device, which will not be described in detail here.

[0064] It should be noted that the metal plate may be a local structure of the housing of the portable ultrasound device, or may be a structural component provided on the housing of the portable ultrasound device.

[0065] Furthermore, in some embodiments, the metal plate is provided with a first positioning column, and an insulating column 5 is sleeved on the end of the first positioning column away from the second insulating member 3 after the first positioning column passes through the second insulating member 3. The first insulating member includes a first insulating fastener 6, and the first insulating fastener 6 passes through the insulating column 5 and is connected to the first positioning column.

[0066] That is to say, in this embodiment, an insulating column 5 is sleeved on the first positioning column, and the insulating column 5 corresponds to the application part. On the one hand, the insulating column 5 can support the application part, and on the other hand, it also plays a role in enhancing insulation and increasing creepage distance. The insulating column 5 cooperates with the second insulating part 3 so that the application part has sufficient creepage distance, so that the application part can meet the voltage resistance requirements between the metal devices in close contact.

[0067] For further information, please refer to Figure 3 In some embodiments, the insulating column 5 includes a cylindrical insulating sleeve 51 and an insulating flange 52. The insulating sleeve 51 is sleeved on the outer periphery of the first positioning column; the insulating flange 52 is provided at the top of the insulating sleeve 51 and convexly protrudes inward along the radial direction of the insulating sleeve 51, and the insulating flange 52 covers the top of the first positioning column. The insulating flange 52 has a center hole 53, and the aperture of the center hole 53 is greater than or equal to the outer diameter of the bottom of the first insulating fastener 6, and less than or equal to the inner diameter of the first positioning column.

[0068] That is, the embodiment utilizes the insulating sleeve body 51 to be sleeved on the outer peripheral portion of the first positioning column, insulates the outer peripheral portion of the first positioning column, and utilizes the insulating flange 52 to cover the top end of the first positioning column, so that the top end of the first positioning column becomes an insulating end face, the hole diameter of the central hole 53 of the insulating flange 52 is greater than or equal to the outer diameter of the bottom of the first insulating fastener 6, so that the first insulating fastener 6 can pass through the central hole 53 to be connected with the first positioning column, and the hole diameter of the central hole 53 of the insulating flange 52 is less than or equal to the inner diameter of the first positioning column, so that the insulating flange 52 can cover the metal end face of the top portion of the first positioning column, thereby insulating the top portion of the first positioning column.

[0069] It should also be noted that the relational terms herein such as first and second and the like are used solely to distinguish one from another entity or action, without necessarily requiring or implying any such actual relationship or order between such entities or actions.
