In order to ensure that the service life and reliability of the screen 100 are both high, the screen 100 may generally include a transparent protective layer 110 disposed at the outermost side, where the transparent protective layer 110 is used to provide protection for the entire screen 100, and the transparent protective layer 110 may be formed of a material such as resin or glass, so as to ensure high transparency and structural strength. Of course, the screen 100 further includes a display layer 130, the display layer 130 is configured to provide an image display function, the display layer 130 is disposed on the inner side of the transparent protective layer 110, and the display layer 130 and the transparent protective layer 110 can form a fixed connection relationship through the adhesive layer 120, so as to ensure that the display layer 130 and the transparent protective layer 110 form an integral structure, and specifically, the adhesive layer 120 can be devices such as adhesive foam. A cavity, i.e., a screen cavity, can be formed between the display layer 130 and the transparent protective layer 110 by the adhesive layer 120. In addition, in order to ensure that the display layer 130 can work normally, the display layer 130 is electrically connected to the first electrical connector 410, so that the first electrical connector 410 is electrically connected to a circuit board of the electronic device, so that the screen 100 and the circuit board can perform power and signal transmission work therebetween.

The circuit board is a main electronic device in the electronic equipment, and can be used as a medium for connecting other devices in the electronic equipment with a power supply and the outside. The circuit board may specifically include a motherboard 310, and parameters such as a shape and a size of the motherboard 310 may be determined according to actual requirements, which are not limited herein.

The front case 200 is a part of a housing in the electronic device, as above, the electronic device may further include a rear case, the front case 200 includes a surrounding frame 201 and a baffle 210, the surrounding frame 201 is in a closed ring structure, the surrounding frame 201 is fixedly connected to one side of the baffle 210, the baffle 210 is a plate-shaped structural member, and the surrounding frame 201 and the baffle 210 can form an installation cavity. During the process of assembling the screen 100 and the front case 200, at least a portion of the screen 100 may be embedded in the inner side of the enclosure frame 201, and the screen 100 may be used to seal the cavity opening of the installation cavity, and the baffle 210 is located on the side of the screen 100 facing away from the display side thereof, that is, the enclosure frame 201 is used to form the cavity wall of the installation cavity, and the baffle 210 is used to form the cavity bottom of the installation cavity, so that in the case that no other hole structure is provided on the front case 200, the display layer 130 in the screen 100 may be ensured to be sealed in the installation cavity.

Specifically, the front case 200 may be formed of a hard material such as metal or plastic, and the specific structure of the front case 200 may be correspondingly designed according to the actual structure of the screen 100. In addition, the enclosure frame 201 and the baffle 210 may be formed in a split molding manner, or the front case 200 may be formed in an integral molding manner, so as to ensure relatively high connection reliability between the enclosure frame 201 and the baffle 210. In addition, the screen 100 and the front case 200 are relatively fixed, and the screen 100 is surrounded and sealed by the surrounding frame 201, so that a closed cavity can be formed between the front case 200 and the screen 100, a relatively independent accommodating environment is provided for the screen 100, impurities such as water vapor and dust on one side of the outside and the baffle 210 away from the screen 100 are prevented from entering a space where the screen 100 is located from a gap between the front case 200 and the screen 100, the display effect of the screen 100 is ensured, and the service life of the screen 100 is relatively long.

Specifically, an annular dispensing layer may be formed on the outer periphery of the screen 100 by means of glue bonding, and the peripheral frame 201 is connected to the screen 100 through the annular dispensing layer, so that the two can form a surrounding sealing relationship while being fixed. Of course, in the case where maintenance or repair of the screen 100 is required, the screen 100 and the front case 200 may be adhered to each other by external force or heating; alternatively, the screen 100 may be brought into a detachable fixed connection relationship with the front case 200 by means of a structure such as a gasket, by means of a detachable connection member such as a screw.

The back shell is fixedly connected to one side of the baffle 210 away from the display side of the screen 100, and the back shell is also a part of a shell in the electronic device and encloses a containing cavity with the baffle 210, and the circuit board is disposed in the containing cavity, and the circuit board is detachably and fixedly connected with the front shell 200 (and/or the back shell) so as to ensure that the electronic device has detachable capability, thereby providing great convenience for maintenance and repair of the electronic device. Specifically, the circuit board may be mounted by means of a connection such as a screw or the like to enable a reliable detachable fixed relationship between the circuit board and the front case 200 (and/or the rear case).

Correspondingly, the camera and the audio component are respectively used for providing the functions of shooting images and recording sounds, and specific parameters of the camera and the audio component can be flexibly selected according to actual requirements, and the method is not limited herein. Meanwhile, the camera and the audio component are also arranged on the front shell and/or the rear shell, so that the positions of the camera and the audio component are fixed, and the camera and the audio component are electrically connected with the circuit board, thereby ensuring that the camera and the audio component can work normally.

In more detail, the transparent protective layer 110 in the screen 100 may be embedded inside the enclosure frame 201, and the transparent protective layer seals the cavity of the mounting cavity, and the display layer 130 is located in the mounting cavity, so that the transparent protective layer, the baffle 210 and the enclosure frame 201 provide a packaging effect for the display layer 130. Based on this, the camera may be mounted on the baffle 210 of the front case 200, and the camera is directed towards the transparent protective layer 110, so as to ensure that the camera can obtain light rays of one side of the transparent protective layer 110 away from the display layer 130. Accordingly, in order to prevent the display layer 130 and the camera from interfering with each other, the adhesive layer 120 and the display layer 130 may be made to avoid the camera, that is, the camera and the display layer 130 correspond to different regions of the transparent protective layer 110, respectively.

The audio component includes a microphone to collect sound information external to the electronic device with the microphone. The microphone may be mounted on the baffle 210, and the sound pickup hole 111 penetrating the transparent protective layer 110 is formed on the transparent protective layer 110, so as to facilitate the external sound signal to be transmitted into the microphone. Accordingly, the microphone faces the sound pickup hole, and in order to prevent the sound pickup hole 111 from damaging the sealed state of the display layer 130, the microphone may be adhered to the transparent protective layer with glue or the like, so that the microphone blocks the sound pickup hole 111. Similarly, the bonding layer 120 and the display layer 130 can also be prevented from avoiding the microphone, so as to prevent the microphone from affecting the normal operation of the display layer 130.

More specifically, the camera and microphone may be made to correspond to the same area of the transparent protective layer 110, for example, the upper portion of the transparent protective layer 110 may be made to correspond to the camera and microphone, and the lower portion of the transparent protective layer may be made to correspond to the display layer 130.

As described above, the sound pickup hole 111 can be prevented from damaging the sealed state of the display layer 130 by blocking the sound pickup hole 111 with the microphone. In another embodiment of the present application, the front shell 200 further includes a first protruding edge 202 and a second protruding edge 203, the first protruding edge 202 and the second protruding edge 203 are both fixed on one side of the baffle 210 facing the surrounding frame 201, and opposite ends of each of the first protruding edge 202 and the second protruding edge 203 extend to the surrounding frame 201, that is, opposite ends of the first protruding edge 202 are both connected with an inner side of the surrounding frame 201, and opposite ends of the second protruding edge 203 are also both connected with an inner side of the surrounding frame 201, so that the surrounding frame 201, the first protruding edge 202 and the second protruding edge 203 can be used as new annular structures to enclose another enclosed space with the transparent protection layer and the baffle 210, and the enclosed space is marked as an inner cavity.

Specifically, the peripheral frame 201, the first protruding edge 202 and the second protruding edge 203 may be adhered to the transparent protective layer 110 by glue or foam, and similarly, the peripheral frame 201, the first protruding edge 202 and the second protruding edge 203 may also form a sealing connection relationship with the baffle 210. In addition, the specific extension directions and dimensions of the first convex edge 202 and the second convex edge 203 may be flexibly selected according to the layout of devices in the electronic apparatus, which is not limited herein.

As described above, in the electronic device, the screen 100 is provided with the first electrical connector 410 for supplying power to the screen 100, transmitting signals, and the like. Considering the conditions of cost, safety, reliability and the like, in the embodiment of the application, the screen 100 and the circuit board can be electrically connected through the connecting devices matched in a plugging manner, so that the purpose of transmitting electric energy and signals is achieved.

In detail, at least a portion of the first electrical connector 410 is located on a side of the bezel 210 facing the screen 100, i.e., at least a portion of the first electrical connector 410 is located on a side of the screen 100 facing the bezel 210, so as to reduce difficulty in forming a connection between the screen 100 and the circuit board, and accordingly, the first electrical connector 410 is electrically connected to the display layer 130 of the screen 100. Meanwhile, the main board 310 of the circuit board is provided with the second electrical connector 420, and at least a part of the second electrical connector 420 is located at one side of the baffle 210 facing the rear shell, so as to ensure that the second electrical connector 420 can form an electrical connection relationship with the circuit board. While for a specific location of the second electrical connector 420, the second electrical connector 420 on the motherboard 310 may alternatively be disposed on a side of the motherboard 310 facing the front case 200, or the second electrical connector 420 may be disposed on a side of the motherboard 310 facing away from the front case 200.

Based on the above technical solution, in order to ensure that the first electrical connector 410 and the second electrical connector 420 can be connected with each other to connect the screen 100 and the circuit board, as shown in the drawing, the baffle 210 of the front case 200 is provided with the first opening 220, and the first electrical connector 410 and/or the second electrical connector 420 extend into the first opening 220, so that a plug-in matching relationship can be formed between the first electrical connector 410 and the second electrical connector 420, thereby achieving the purpose of forming an electrical connection relationship between the first electrical connector 410 and the second electrical connector 420, and ensuring that the reliability of the electrical connection relationship between the two is relatively high. Specifically, the size and shape of the first opening 220 may be determined according to the shape and size of the first electrical connector 410 and/or the second electrical connector 420, which is not limited herein.

Meanwhile, by matching the sealing member with the first opening 220 to seal the first opening 220, the sealing state of the space where the screen 100 is located is ensured not to be affected by the first opening 220 arranged on the front case 200, and further, the space where the screen 100 is located can be always isolated from other spaces of the electronic device and other spaces of the electronic device. In the case that the second electrical connector 420 is disposed in a different manner, the manner in which the sealing member seals the first opening 220 may be various, such as dispensing sealing, or hot melt sealing, etc., which are not limited herein.

The embodiment of the application discloses an electronic device, which comprises a screen 100, a circuit board, a front shell 200, a first electric connector 410, a second electric connector 420, a camera, an audio component, a rear shell and a sealing piece, wherein the camera and the audio component are respectively used for providing the functions of image shooting and sound recording, so that the electronic device can be ensured to be used as a visual communication device. The first electrical connector 410 is electrically connected with the screen 100, the second electrical connector 420 is electrically connected with the main board 310, the front case 200 includes a surrounding frame 201 and a baffle 210, the screen 100 is embedded in the inner side of the surrounding frame 201, the screen 100 seals an orifice of a mounting cavity formed by connecting the surrounding frame 201 and the baffle 210, the baffle 210 is located on one side of the screen away from the display side of the screen, and at least one part of the first electrical connector 410 is located on one side of the baffle 210 facing the screen 100.

The circuit board is located the baffle 210 and deviates from the one side of screen 100, and the circuit board is held in the holding chamber that backshell and baffle 210 formed, and second electric connector 420 is connected with the circuit board, and at least a portion of second electric connector 420 is located the baffle 210 and faces one side of backshell, and then, through set up first opening 220 on the baffle 210 of preceding shell 200, so that first electric connector 410 and/or second electric connector 420 can stretch into first opening 220, guarantee that first electric connector 410 can form the grafting relation with second electric connector 420, and then guarantee that circuit board and screen 100 can form electric connection relation.

Meanwhile, the sealing member is matched with the first opening 220 to seal the first opening 220, so that the space where the screen 100 is located, namely, the space of one side of the baffle 210, which is away from the circuit board, in the electronic equipment can be sealed, and further, the screen 100 is prevented from being corroded by external moisture, dust or other impurities.

Based on the above embodiment, in order to ensure that a separate receiving space can be formed in the baffle 210 on the side where the screen 100 is located, without being affected by the first opening 220, it is necessary to provide a sealing member for the first opening 220. In this regard, in one embodiment of the present application, optionally, the second electrical connector 420 is located on a side of the circuit board facing the baffle 210, which may reduce the difficulty of connection between the first electrical connector 410 and the second electrical connector 420, and may reduce the difficulty of sealing the first opening 220.

In this regard, optionally, in the electronic device disclosed in the embodiment of the present application, the circuit board includes a main board 310, the second electrical connector 420 is electrically connected to the main board 310, the sealing member includes a first sealing ring 510, the first sealing ring 510 is a closed annular structural member, and the first sealing ring 510 is disposed between the front shell 200 and the main board 310 in an extrusion manner, so that the front shell 200 and the main board 310 can form a relatively tight fitting relationship with the first sealing ring 510; meanwhile, the first sealing ring 510 surrounds the outside of the first opening 220, so that the first sealing ring 510 can provide a surrounding sealing effect for the first opening 220, ensure that the first opening 220 cannot communicate with a gap space located between the front shell 200 and the main board 310 in the periphery of the first sealing ring, and provide a blocking effect for the end of the first opening 220 by using the main board 310, so as to prevent the space on the side of the screen 100 in the front shell 200 from communicating with the outside through the first opening 220, and achieve the purpose of sealing the first opening 220.

Specifically, the first sealing ring 510 may be formed of an elastic material such as rubber, so as to ensure that the space inside the first sealing ring 510 can be isolated from the space outside the first sealing ring 510 in the case where the first sealing ring 510 is pressed between the main board 310 and the front case 200. In addition, the shape of the first sealing ring 510 may be correspondingly set according to the shape of the first opening 220, and the shape of the first sealing ring 510 is simpler as a whole, for example, the first sealing ring 510 may be in a (approximate) circular ring shape or a (approximate) rectangular ring shape structure, so as to further improve the sealing effect of the first sealing ring 510.

In order to further enhance the sealing effect of the first sealing ring 510 on the first opening 220, optionally, a first sealing rib 230 is further disposed on a side of the baffle 210 facing the main board 310 of the circuit board, the first sealing rib 230 surrounds the outside of the first opening 220, and the first sealing rib 230 is in annular sealing fit with the first sealing ring 510. That is, similar to the first seal ring 510, the first seal bead 230 is also a closed ring structure and has the same or similar shape as the first seal ring 510, thereby ensuring that the first seal ring 510 can be mated with the first seal bead 230 in a complete circle to compress the first seal ring 510 with the first seal bead 230 into a complete ring-like sealing relationship.

Specifically, the first sealing bead 230 may be formed along with the process of the baffle 210 to ensure the structural reliability of the first sealing bead 230. In addition, the protruding dimension of the first sealing rib 230 along the thickness direction of the main board 310 is not required to be too large, so that the first sealing rib 230 and the first sealing ring 510 are prevented from sliding, and high stability between the first sealing rib 230 and the first sealing ring 510 is ensured all the time. In addition, the dimension of the first sealing ring 510 in the self "radial direction" (i.e., any direction from the center of the first sealing ring 510 to the outside of the first sealing ring 510 along the direction perpendicular to the thickness of the main board 310) may be larger than the dimension of the first sealing rib 230, so that the first sealing rib 230 is "covered" by the first sealing ring 510, which may further improve the sealing performance therebetween.

Further, a mating groove may be provided at a side of the first sealing ring 510 facing the front case 200, and the mating groove is in a closed ring structure, so that the mating groove can be provided around the first opening 220. On this basis, when the electronic device is assembled, along the thickness direction of the circuit board, a portion of the first sealing rib 230 may be embedded into the mating groove, and in the case where the first sealing ring 510 is disposed between the main board 310 and the front case 200 by extrusion, by adopting the foregoing technical solution, on one hand, the first sealing ring 510 may be further prevented from sliding laterally with respect to the first sealing rib 230, and on the other hand, the contact area between the first sealing ring 510 and the first sealing rib 230 may be increased, so as to further improve the sealing reliability between the two.

Specifically, the size of the mating groove provided on the first seal ring 510 in the aforementioned "radial direction" is slightly larger than the size of the first seal bead 230 in the aforementioned direction, so that the clearance between the first seal bead 230 and the mating groove is reduced as much as possible while ensuring that the first seal bead 230 can extend into the mating groove to mate with the first seal ring 510, and the sealing effect provided by the first seal ring 510 is maximized.

As described above, the screen 100 may perform the interaction of electric energy and signals with the motherboard 310 by the first electrical connector 410 and the second electrical connector 420 that are in plug-in fit, and the specific structural forms of the first electrical connector 410 and the second electrical connector 420 may be various, and optionally, the first electrical connector 410 includes a wire and a connector, and the second electrical connector 420 is a connector, and the connector is used for plug-in fit with the connector. Correspondingly, the joint and the connector are a group of mutually matched devices, and the purpose of electric connection can be realized through plug-in matching.

In this case, the connector may form a reliable electrical connection relationship with the screen 100 through the conductive wires, and is affected by the deformable effect of the conductive wires, so that the first opening 220 on the baffle 210 does not need to be disposed opposite to the connection portion of the conductive wires on the screen 100, and further, the specific position of the first opening 220 may be flexibly determined according to the actual layout situation of the functional devices on the front case 200 and the motherboard 310, and by deforming the conductive wires, the connector of the first electrical connector 410 may be ensured to form an electrical connection relationship with the second electrical connector 420 through the first opening 220.

Of course, in the above embodiment, the second electrical connector 420 may be disposed opposite to the first opening 220, and at least a portion of the second electrical connector 420 may extend into the first opening 220, so that, on one hand, a connection relationship with the first electrical connector 410 is facilitated, and, on the other hand, the size of the entire electronic device in the thickness direction of the motherboard 310 may be reduced.

In another embodiment of the present application, one of the first electrical connector 410 and the second electrical connector 420 is a male BTB connector, the other is a female BTB connector, and the two connectors are connected in a plugging manner, and form an electrical connection relationship, so that the assembly difficulty of the connection device is relatively small, the installation is convenient, and the reliability is relatively high. Of course, in the case of the above-mentioned technical solution, it is necessary to make the first electrical connector 410 and the second electrical connector 420 opposite to the first opening 220, so as to ensure that the first opening 220 is used to form a plug-in mating relationship.

As described above, the second electrical connector 420 may be located on a side of the main board 310 of the circuit board facing the bezel 210, and in another embodiment of the present application, the second electrical connector 420 may also be located on a side of the main board 310 of the circuit board facing away from the bezel 210, which may effectively utilize a space on a side of the main board 310 facing away from the bezel 210 (i.e., between the main board 310 and the rear case).

Based on this, to ensure that the first electrical connector 410 is able to form a mating relationship with the second electrical connector 420, the first electrical connector 410 may include wires and connectors such that the wires are used to draw power from the bezel 210 toward the side of the screen 100 to the side of the bezel 210 facing away from the screen 100. That is, the connector of the first electrical connector 410 can drive the wires to pass through the first opening 220 to the side of the baffle 210 facing away from the screen 100, and form a plug-in mating relationship with the second electrical connector 420 of the side of the main board 310 facing away from the baffle 210.

Accordingly, in order to ensure that the space of the side of the baffle 210 facing the screen 100 can still form an independent space, in this embodiment, the sealing member includes a sealing foam 820, and the sealing foam 820 is provided with a perforation, and the first electrical connector 410 is disposed through the perforation, so that a portion of the wires and the connector in the first electrical connector 410 can pass out to the side of the front case 200 facing away from the screen 100. Specifically, the sealing foam 820 may be a unitary structure with a portion cut out at a central region thereof to form the aforementioned perforations; alternatively, the sealing foam 820 may include two independent parts, and after the connector is pulled out from the side of the front case 200 where the screen 100 is located through the first opening 220, the two sealing foam 820 are adhered to opposite sides of the conductive wire of the first electrical connector 410, so that a gap (i.e. a perforation) between the two sealing foam 820 is as small as possible, so as to reduce the difficulty of sealing the perforation.

Accordingly, in order to seal the through hole, the first electrical connector 410 and the inner wall of the through hole may be sealed by dispensing, that is, after the first electrical connector 410 is installed in the through hole, the through hole may be plugged by dispensing, so as to prevent leakage at the through hole, and the space on the side of the screen 100 in the baffle 210 cannot form a complete independent space.

In addition, in order to improve connection reliability between the sealing foam 820 and the front case 200, a limit frame 260, that is, an annular protrusion structure, may be disposed on one side of the front case 200 facing the main board 310, the limit frame 260 is disposed around the first opening 220, and a preset gap is disposed between an inner wall of the limit frame 260 and an edge of the first opening 220, so as to provide a bearing function for the sealing foam 820, improve connection reliability between the sealing foam 820 and the front case 200, and limit a position of the sealing foam 820 by the limit frame 260, so that a stability of cooperation between the sealing foam 820 and the front case 200 may be further improved.

Generally, an electronic device is provided with a card swiping component, so that a user can achieve the purposes of unlocking an access control and the like by means of attaching a carrier such as a card written with a preset communication protocol to the card swiping component. Generally, to ensure that the sensitivity of the card swiping assembly is relatively high, the card swiping assembly may be positioned on the side of the bezel 210 facing the screen 100, which positions the card swiping assembly relatively outward in the electronic device, facilitating reading of the corresponding card swiping data. However, to ensure proper operation of the card swiping assembly, the card swiping assembly also needs to be interconnected with the motherboard 310 on the side of the bezel 210 facing away from the screen 100.

Based on the above, in the case where the electronic device disclosed in the embodiments of the present application includes the first electrical connector 410, the card swiping antenna 910 of the card swiping assembly may be electrically connected to the first electrical connector 410, so that the card swiping antenna 910 may indirectly form an electrical connection relationship with the motherboard 310 by using the first electrical connector 410. Specifically, the screen 100 may be provided with an antenna connection base 140 electrically connected to the first electrical connector 410, and the card swiping antenna 910 included in the card swiping assembly may be provided with an antenna connection wire 920, where the antenna connection wire 920 may form a connection relationship with the antenna connection base 140 in advance, so as to ensure that the card swiping antenna 910 and the motherboard 310 can be connected after the first electrical connector 410 and the motherboard 310 are connected to each other.

In order to further improve the reliability of the electronic device, the electronic device further includes a conductive member, and the baffle 210 is provided with a grounding opening, which is disposed through the baffle 210, so as to ensure that components located on two opposite sides of the baffle 210 can form a grounding relationship through the grounding opening. The conductive member may be formed of a conductive material such as metal, and may be a block or columnar structure; in addition, the conductive member is plugged in the grounding opening, which also enables the conductive member and the baffle 210 to form a relatively fixed relationship, specifically, the conductive member can be embedded in the baffle 210 by means of integral injection molding and the like, so that the conductive member can be ensured to plug the grounding opening of the baffle 210; alternatively, glue or the like may be used to seal the conductive member to the ground opening. Meanwhile, by designing the position and state of the conductive member in the barrier 210, the screen 100 can be in contact fit with the conductive member under the condition that the screen 100 and the barrier 210 form a fixed connection relationship, so that the screen 100 and the conductive member form an electrical connection relationship.

Specifically, according to the positional correspondence between the baffle 210 and the screen 100, the conductive member can be made to correspond to the area with the conductive capability in the screen 100, and by making the conductive member protrude or be flush with the surface of the baffle 210 facing the side of the screen 100, it is ensured that after the screen 100 is fixedly connected with the baffle 210, the screen 100 can be in contact fit with the conductive member, and an electrical connection relationship is formed. Of course, in order to prevent the spaces on the opposite sides of the baffle 210 from being communicated with each other through the conductive member, the conductive member may be a solid structural member, or one end of the conductive member may be plugged, and the outer periphery of the conductive member is in sealing connection with the front case 200.

Meanwhile, the circuit board is electrically connected with the conductive member, so that the screen 100 can be indirectly electrically connected with the circuit board through the conductive member, and the grounding stability of the screen 100 is ensured. Specifically, the circuit board and the conductive member may be electrically connected in a contact manner, or the circuit board and the conductive member may be connected by using conductive connecting members, so that a stable electrical connection relationship between the circuit board and the conductive member may be ensured.

As shown in fig. 3, further, the conductive member includes a blind nut 240, that is, the conductive member is a nut of a relatively special structure, the threaded hole of which is not a through hole but a blind hole, and the blind nut 240 has an opening toward the side of the baffle 210 where the circuit board is located. Meanwhile, the electronic device further comprises a conductive screw 700, and the circuit board is connected with the blind nut 240 through the conductive screw 700, so that the circuit board and the screen 100 can be electrically connected while the circuit board and the baffle 210 are detachably and fixedly connected, and further, the reliability of the electrical connection relationship between the circuit board and the screen 100 is improved while the processing procedure is reduced. In addition, in order to ensure that the contact matching relationship between the conductive member and the screen 100 is relatively stable, the conductive foam 810 can be arranged between the conductive member and the screen 100, so that on one hand, the reliability of power connection between the screen 100 and the conductive member can be improved, on the other hand, a damping effect can be provided for the conductive member and the screen 100, and the service life of the device is prolonged.

Specifically, the blind nut 240 and the conductive screw 700 may be made of a material having a conductive capability such as metal and a relatively high structural strength, and more specifically, the conductive nut and the conductive screw 700 may be made of copper metal to ensure a better conductive capability. In addition, in order to ensure that the fixed connection relationship between the circuit board and the baffle 210 is reliable, the number of the blind nuts 240 and the conductive screws 700 is multiple, and the conductive screws 700 and the blind nuts 240 are matched in a one-to-one correspondence, and the blind nuts 240 and the baffle 210 are sealed, so that the space of the baffle 210 on the side where the screen 100 is located is still ensured to be an independent space, and a reliable packaging effect is provided for the screen 100.

As described above, the side of the baffle 210 facing the screen 100 can form a relatively independent accommodating space, and prevent the baffle 210 from entering moisture and dust outside the side facing away from the screen 100 and the electronic device, considering that along with the increase of the service life of the electronic device, a very small amount of moisture may still enter the space of the side of the baffle 210 facing the screen 100, so in this embodiment, optionally, a drying device is disposed between the screen 100 and the baffle 210, and in particular, the drying device may be a drying agent, and of course, the drying device may also be an energy-consuming device. The drying device may be fixed in the space between the screen 100 and the barrier 210 by means of bonding or the like.

In another embodiment of the present application, the drying device may be detachably fixed in the space between the screen 100 and the barrier 210 by means of a snap fit or the like. Based on this, in order to facilitate replacement of the drying device, the baffle 210 may be optionally provided with a second opening, and the second opening is disposed opposite to the drying device, so that the drying device may be replaced with the second opening, and accordingly, the size and shape of the second opening may be correspondingly determined according to the size and shape of the drying device, ensuring that the drying device is easily taken out and loaded from the second opening.

Accordingly, since the second opening is also in communication with the space on the side of the screen 100 in the baffle 210, in order to ensure that the space on the side of the screen 100 in the baffle 210 still has independence, optionally, in this embodiment, the electronic device further includes a second sealing ring 520, similar to the first sealing ring 510, the second sealing ring 520 is a closed ring structure, the second sealing ring 520 is pressed between the front case 200 and the circuit board, and the second sealing ring 520 surrounds the second opening, so that the space on the side of the baffle 210 facing the screen 100 is not affected by the second opening and is in communication with the space on the side of the baffle 210 facing away from the screen 100 (or the space outside the electronic device), so that the screen 100 can still be in a relatively independent accommodating space.

Specifically, the second sealing ring 520 may also be made of rubber, and similar to the first sealing ring 510, a mating groove may also be disposed on a side of the second sealing ring 520 facing the screen 100, and by providing the mating groove with the second sealing rib 270, a portion of the second sealing rib 270 may extend into the mating groove, so as to ensure that the second sealing ring 520 may provide a more reliable sealing effect for the second opening.

In addition, in this embodiment, the second sealing ring 520 may be pressed between the circuit board and the front case 200, and considering that the circuit to be disposed on the main board 310 may not need to be excessive, or that the second opening is relatively remote from the electronic device, alternatively, the circuit board includes the sealing platen 320 and the main board 310, the main board 310 and the sealing platen 320 are separately disposed, and the first sealing ring 510 may be pressed between the main board 310 and the baffle 210, and the second sealing ring 520 may be pressed between the sealing platen 320 and the baffle 210, and the relative position between the sealing platen 320 and the main board 310 may be flexibly designed according to the specific position of the second opening, which is not limited herein.

In the embodiments described above, the differences between the embodiments are mainly described, and as long as there is no contradiction between the different optimization features between the embodiments, the different optimization features may be combined to form a better embodiment, and in consideration of brevity of line text, the description is omitted here.
