[0003] In environments containing harmful gases (gases that may affect the performance of electronic devices), sealing is typically achieved through film coating or plating. However, film coating is technically challenging, and its effectiveness in protecting against harmful gases is limited, especially under high pressure, where the protective gas can easily penetrate the film or coating area through gaps. Furthermore, in some electronic products with image display or light signal output functions, film coatings can affect light transmission efficiency, leading to reduced brightness or color distortion.

[0046] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0047] Figure 1 illustrates the structure of an electronic device packaging structure 100 according to some embodiments of the present invention. The packaging structure 100 will be described below with reference to Figure 1. The packaging structure 100 is applied in an electronic device; for example, the packaging structure 100 includes the casing of the electronic device and other components with packaging functions, which will be described in detail in subsequent embodiments.

[0048] Referring to Figure 1, the encapsulation structure 100 includes a front-end module 110, a connecting portion 120, and a rear-end module 130. The connecting portion 120 is located on one side of the front-end module 110 and is sealed relative to the front-end module 110. For example, the outer periphery of the connecting portion 120 is integrally formed with the front-end module 110, or the connecting portion 120 and the front-end module 110 are glued, fixed, and sealed at the connection position.

[0049] The rear module 130 is sealed to the connecting part 120. For example, in some embodiments, the outer peripheral structure of the rear module 130 and the connecting part 120 is integrally formed, or the rear module 130 and the connecting part 120 are glued and sealed at the connection position.

[0050] The connecting portion 120 protrudes relative to the front-end module 110 and is located between the front-end module 110 and the rear-end module 130. The front-end module 110 is sealed relative to the rear-end module 130 through the connecting portion 120. The sealing degree of the front-end module 110 and the rear-end module 130 does not affect each other. In this embodiment, the front-end module 110 and the rear-end module 130 are independent of each other and are connected by the connecting portion 120. The independence of the front-end module 110 and the rear-end module 130 means that the front-end module 110 and the rear-end module 130 have independent structures and are both sealed and connected to the connecting portion 120, forming two independent modules. The connecting portion 120 has a groove 121. In some embodiments, the connecting portion 120 protrudes from the front-end module 110, and the groove 121 is located inside the connecting portion 120. The groove 121 can be used to cooperate with an electrical connector to realize an electrical connection between the interior of the front-end module 110 and the interior of the rear-end module 130.

[0051] In practical applications of electronic devices, the front-end module 110 and the back-end module 130 are independent of each other and are both sealed to the connecting part 120. Electronic components located in the front-end module 110 and the back-end module 130 can be processed separately. Furthermore, the seams at the connection points between the front-end module 110, the back-end module 130, and the connecting part 120 are small, providing ample operating space and facilitating sealing, thus meeting the sealing requirements of the electronic device. Moreover, the front-end module 110 and the back-end module 130 enable modularity of the electronic device, facilitating replacement, repair, or upgrades, and reducing maintenance costs.

[0052] Referring to Figure 1, in some embodiments, the connector 120 includes a sidewall 122, an adapter plate 123, a front cable 124, and a rear cable 125.

[0053] The sidewall 122 is disposed on the side of the front-end module 110 facing the rear-end module 130. For example, the sidewall 122 is fixedly connected to or integrally formed with the outer shell of the front-end module 110. The sidewall 122 circumferentially surrounds the groove 121, forming a recess facing the front-end module 110. In a preferred embodiment of the present invention, the sidewall 122 completely surrounds the circumference of the groove 121, and the groove 121 forms an opening facing the rear-end module 130.

[0054] An adapter plate 123 is disposed within a groove 121. In some embodiments, the shape of the adapter plate 123 matches that of the groove 121, and the adapter plate 123 can be embedded within the groove 121. Figure 2 illustrates the structure of the adapter plate 123 according to some embodiments of the present invention. Referring to Figure 2, the adapter plate 123 includes a front end interface 126 and a rear end interface 127.

[0055] One end of the front-end cable 124 is electrically connected to the front-end interface 126, and the other end of the front-end cable 124 extends to the front-end module 110. One end of the rear-end cable 125 is electrically connected to the rear-end interface 127, and the other end of the rear-end cable 125 extends to the rear-end module 130.

[0056] In this embodiment, the connecting part 120 can realize the electrical connection between the front-end module 110 and the back-end module 130 using the adapter plate 123, the front-end cable 124, and the back-end cable 125. In some embodiments, some electronic components in the electronic device are disposed in the front-end module 110 and others are disposed in the back-end module 130, and are electrically connected through the connecting part 120. The adapter plate 123 can be used only for electrical connection and signal transmission without further processing, which helps to reduce the size of the adapter plate 123, reduce the size of the connecting part 120, reduce the contact area between the connecting part 120 and the front-end module 110 and the back-end module 130, reduce sealing difficulty, and improve sealing effect.

[0057] In some embodiments, the adapter board 123 may include a circuit board, and the front-end interface 126 and the rear-end interface 127 may include terminal blocks, with the front-end cable 124 and the rear-end cable 125 plugged into the terminal blocks. In some embodiments, the front-end structure 126 and the rear-end interface 127 may be respectively disposed on both sides of the circuit board and connected by vias or by slotted lines on the side of the circuit board, which helps to simplify the structure of the adapter board 123 and reduce the packaging difficulty.

[0058] Referring to Figure 2, in some embodiments, the adapter plate 123 includes a filling groove 128. Resin is filled into the filling groove 128 to seal the connection portion 120 relative to at least one of the front-end module 110 or the rear-end module 130. In some embodiments, resin may be filled between the recess 121 and the filling groove 128 to close the opening of the recess 121 facing the rear-end module 130, thereby sealing the adapter plate 123.

[0059] In some embodiments, the depth of the filling groove 128 is greater than the height of the front-end interface 126. Filling the filling groove 128 with resin can seal the front-end interface 126 and fix the front-end cable 124. In some embodiments, the adapter plate 123 has filling grooves 128 on both sides facing the front-end module 110 and the rear-end module 130. In some embodiments, the adapter plate 123 can also be sealed with the rear-end module 130 by filling the filling groove 128 with resin.

[0060] Preferably, the filling groove 128 faces the front-end module 110. By filling the groove 121 and the filling groove 128 with resin, the connection portion 120 can be sealed and the adapter plate 123 can be fixed. In some embodiments, the front-end cable 124 passes through the housing of the front-end module 110 at the bottom of the groove 121 and extends into the interior of the front-end module 110. Injecting resin into the interior of the groove 121 can seal the location where the front-end cable 124 extends into the front-end module 110.

[0061] In some embodiments, the filling groove may also be disposed within the recess 121, for example, within the circumferential surrounding area of ​​the sidewall 122. The filling groove located within the recess 121 can be supported on the edge of the adapter plate 123, and the filling groove can accommodate the front-end interface 126, protecting the front-end interface 126 and the front-end cable 124.

[0062] In some embodiments, the adapter plate 123 has an adhesive coating on one or both sides. For example, in some embodiments, an adhesive coating is formed on both sides of the adapter plate 123, and the adapter plate 123 is adhered and fixed in the groove 121. Preferably, both sides of the adapter plate 123 have an adhesive coating, and the adapter plate 123 and the outer shell surface of the rear module 130 are adhered and fixed, which helps to improve the sealing performance of the connection part 120 and the rear module 130 and reduces the sealing difficulty.

[0063] In some embodiments, the adapter plate 123 can also be fixed in the groove 121 by bolts. The multiple connections of the filling groove 128, adhesive coating, and bolts improve the stability of the adapter plate 123 and seal it. Furthermore, in some embodiments, the adapter plate 123 can be fixedly connected to the housing of the front-end module 110 by bolts.

[0064] In some embodiments, at least one of the front-end module 110 or the back-end module 130 includes a housing. For example, Figures 3A and 3B show a housing 111 of the front-end module 110. The housing 111 has a cavity in which electronic components of an electronic device can be accommodated. For example, the housing 111 includes a front shell and a rear shell that snap together and seal against each other, with the electronic components fixed between the front shell and the rear shell.

[0065] Referring to Figure 3A, the housing 111 includes mounting holes 112. The mounting holes 112 are located on the surface of the housing 111 between the front-end module 110 and the rear-end module 130. In some embodiments, the rear-end module 130 includes a housing, and the housing of the rear-end module 130 may also have mounting holes on the surface between the rear-end module 130 and the front-end module 110.

[0066] Mounting hole 112 protrudes from the surface of housing 111 and has a U-shaped groove. Housing 111 is fixedly connected to mounting hole 112 at the location of bolt 113, and bolt 113 is recessed and sealed into the U-shaped groove of mounting hole 112. In some embodiments, front and rear housings of housing 111 can be fixedly connected by bolt 113, or electronic components within the cavity of housing 111 can be fixedly connected by bolt 113, or the encapsulation structure 100 is fixed to the mounting surface, and housing 111 is fixedly connected to the mounting surface by bolt 113. Mounting hole 112 and bolt 113 help improve the structural stability of encapsulation structure 100.

[0067] In some embodiments, the bolt 113 penetrates into the cavity of the housing 111. The mounting hole 112 can be sealed by filling the U-shaped groove with resin, thereby improving the stability of the bolt 113 connection. The U-shaped groove has circumferentially closed sides, which can limit the area to which the resin is filled, reduce processing difficulty, and prevent resin from contaminating other areas.

[0068] Furthermore, according to a preferred embodiment of the present invention, a sealing gasket (not shown in the figure) is also provided in the mounting hole 112. Specifically, the sealing gasket may include silicone or rubber gaskets, which is beneficial to improving the sealing performance of the mounting hole 112.

[0069] In some embodiments, the mounting hole 112 is located outside the area of ​​the connector 120, and the size of the connector 120 is reduced relative to the sizes of the front end module 110 and the rear end module 130. This helps to reduce sealing difficulties and facilitates the installation of electronic devices.

[0070] Referring to Figure 4, in some embodiments, the front-end module 110 includes a housing 111. A first through-hole 114 is included on the side of the housing 111 furthest from the rear-end module 130. A breathable membrane 115 is disposed at the location of the first through-hole 114. Some electronic components in the electronic device are disposed inside the housing 111. During operation, the electronic components generate heat, leading to increased internal pressure in the housing 111, which is detrimental to the structural stability of the housing 111. In this embodiment, the first through-hole 114 is provided on the side of the housing 111 furthest from the rear-end module 130, and a breathable membrane 115 is provided on the outside of the first through-hole 114. This can release the internal pressure of the housing 111 and reduce the entry of external substances, such as dust, into the housing 111, affecting the performance of the electronic components. In some embodiments, the permeability of the breathable membrane can be set according to the power and thermal efficiency of the electronic components.

[0071] Referring to Figure 3B, in some embodiments, the housing 111 further includes a second through-hole 116. The second through-hole 116 extends to the side of the housing 111 away from the distal module 130. The second through-hole 116 includes a U-shaped groove. The encapsulation structure 100 includes a light guide 140 that is recessed and sealed within the U-shaped groove at the location of the second through-hole 116.

[0072] In some embodiments, the electronic device includes a light source, the position of which may correspond to the light guide 140, emitting light signals outward. The connection between the light guide 140 and the housing 111 is sealed by a U-shaped groove in the second through hole 116. Resin can be filled into the U-shaped groove at the location of the second through hole 116. Furthermore, a gasket can be provided between the second through hole 116 and the light guide 140 to improve the sealing performance of the housing 111.

[0073] Referring to Figure 4, in some embodiments, the housing 111 further includes a third through hole 117, and an elastic membrane (not shown in the figure) is provided at the location of the third through hole 117. In some embodiments, the elastic membrane can bulge outward or contract inward. The elastic membrane can be used to balance the pressure inside and outside the housing 111, improve the structural stability of the housing 111, and help ensure the sealing of the inside of the housing 111.

[0074] As shown in Figure 4, in some embodiments, the outer shell 111 includes a first through hole 114 and a third through hole 117. The breathable membrane 115 at the location of the first through hole 114 can reduce the internal pressure of the outer shell 111. Combined with the elastic membrane at the location of the third through hole 117, the elastic deformation of the elastic membrane can reduce the pressure borne by the breathable membrane 115, improving the stability of the connection between the breathable membrane 115 and the first through hole 114. For example, if the internal pressure of the outer shell 111 is too high, causing the permeability of the breathable membrane 115 to be insufficient to quickly reduce the internal pressure, the elastic deformation of the elastic membrane can reduce the risk of the breathable membrane 115 being squeezed and detached, improving the structural stability of the outer shell 111.

[0075] An embodiment of this utility model also includes a human-machine interface 200. Figure 5 shows the structure of the human-machine interface 200. Referring to Figure 5, the human-machine interface 200 includes an encapsulation structure 100, a display panel 210, and a processor 220 as described in the foregoing embodiments. The display panel 210 is disposed within the front-end module 110 of the encapsulation structure 100. The processor 220 is disposed within the rear-end module 130 of the encapsulation structure 100. In some embodiments, the display panel 210 and the processor 220 communicate, for example, through wireless communication or through a connection portion 120 in the encapsulation structure 100.

[0076] In some embodiments, the human-machine interface 200 can interact with a user. For example, the user can obtain information through the display panel 210, or the display panel 210 includes a touchscreen, through which the user can input commands. The processor 220 communicates with the display panel 210 and can control the information output by the display panel 210 or receive commands input by the user through the touchscreen.

[0077] Referring to Figure 5, in some embodiments, the human-machine interface 200 further includes a light source 230. The encapsulation structure 100 includes a light guide, such as the light guide 140 described in the preceding embodiments. The light source 230 is disposed inside the front-end module 110, for example, inside the housing of the front-end module 110, and emits light signals outward through the light guide. The light source 230 can serve as an indicator light for the human-machine interface 200, communicate with the processor 220, and be controlled by the processor 220 to emit preset light signals. In some embodiments, the light source 230 can also serve as a backlight for the display panel 210, for example, set to be constantly on.

[0078] The encapsulation structure 100 divides the human-machine interface 200 into two parts. The display panel 210 and the back-end module 130, located in the front-end module 110, are isolated from the environment in which the back-end module 130 is located while maintaining signal connectivity, reducing the impact of the environment on the human-machine interface 200. The front-end module 110 and the back-end module 130 can be in different operating environments. For example, the display panel 210 is sensitive to high-pressure gas environments or protective gas environments, while the processor 220 is not sensitive to high-pressure gas environments or protective gas environments. In some embodiments, the front-end module 110 and the display panel 210 can be placed in an atmospheric pressure environment, while the back-end module 130 and the processor 220 can be placed in a high-pressure gas environment or a protective gas environment. This ensures the functionality of the human-machine interface 200 while reducing sealing difficulty and improving sealing stability.

[0079] This utility model also includes a distribution box 300. Figure 6 shows the structure of the distribution box 300 according to some embodiments of this utility model. Referring to Figure 6, the distribution box 300 includes a box body 310, electrical components 320, and a human-machine interface 200 as described in the foregoing embodiments.

[0080] The enclosure 310 is filled with a protective gas, such as nitrogen. Electrical components 320 are disposed inside the enclosure 310, and can be used, for example, to realize the functions of the distribution box 300. The human-machine interface 200 is embedded in the enclosure 310, and in the encapsulation structure 100 of the human-machine interface 200, the front-end module 110 is located on the outside of the enclosure 310, and the rear-end module 130 is located on the inside of the enclosure 310.

[0081] In some embodiments, to reduce the risk of arcing and fire inside the distribution box 300 and to prevent oxidation of the electrical components 320, a protective gas is filled inside the box 310. The protective gas can be, for example, nitrogen, which helps reduce costs. Alternatively, in some embodiments, an inert gas, such as helium, neon, or argon, can be selected as the protective gas. Preferably, the pressure inside the distribution box 300 can be increased to protect the electrical components 320 using high-pressure gas; the pressure, for example, is 0.05-0.1 MPa. Using high-pressure protective gas can protect the electrical components 320 inside the distribution box 300, reducing fire risks and extending the service life of the electrical components 320.

[0082] Some protective gases, such as nitrogen, may deposit under the influence of high temperature and high pressure electric arcs. Alternatively, the purity of the protective gas may be limited, containing impurities that may also deposit under the influence of high temperature and high pressure electric arcs. Furthermore, under high pressure conditions within the enclosure 310, the protective gas may enter the human-machine interface through gaps in the membrane seal or coating seal, affecting performance.

[0083] In this embodiment, the human-machine interface 200 in the distribution box 300 is divided into a front-end module and a back-end module by the encapsulation structure 100. The display panel, which is susceptible to the protective gas, is located inside the front-end module, outside the enclosure 310, under atmospheric pressure. This minimizes the impact of the protective gas on the processor inside the back-end module. Located inside the enclosure 310, it can communicate with the electrical components 320 to obtain their operating status. The front-end module and the back-end module are connected by a connecting part, and the front-end module is sealed relative to the back-end module. The location of the connecting part facilitates sealing and ensures good sealing stability, enabling the human-machine interface 200 to operate stably for a long period.

[0084] Finally, it should be noted that the above descriptions are merely embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
