Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] In electronic devices such as mobile phones, a shell is usually clamped between the display screen and the back cover to form the overall external structure of the electronic device. Of course, in order to facilitate the assembly of the shell between the display screen and the back cover, the shell usually adopts a detachable structure, which includes a separately molded shell body and a frame, wherein the frame is arranged around the outer periphery of the shell body, and the shell body is connected to both the frame and the display screen, so that the frame can be indirectly fixed to the display screen.

[0003] The frame usually includes a fixedly connected side portion and a connecting portion, the connecting portion is located on the inner side of the side portion, and the connecting portion is sandwiched between the shell body and the back cover. At present, double-sided tape is usually provided on both opposite sides of the connecting portion, and two layers of double-sided tape are used to form a fixed connection relationship between the back cover, the connecting portion and the shell body. However, an antenna is usually provided on the inner surface of the side portion of the frame, and the antenna extends to the connecting portion. On the one hand, due to the poor sealing effect between the end of the side portion away from the connecting portion and the shell body, impurities such as water vapor and dust can easily invade between the side portion and the shell body, thereby corroding and damaging the antenna. On the other hand, since the antenna extends to the connecting portion, it is also easy to damage the antenna in the process of separating the double-sided tape to disassemble the frame, resulting in an increase in the maintenance cost of the product. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device to solve the problem that the antenna arranged on the frame in the current electronic device is easily damaged.

[0005] The embodiment of the present application discloses an electronic device, which includes a frame, a shell body, a back cover, a first flexible sealing member and an antenna, wherein: The frame includes a side portion and a buckle, the side portion is arranged around the outer periphery of the shell body, and the first end of the side portion is sealed and connected to the back cover, the buckle is connected to the inner side of the second end of the side portion, and the antenna is installed on the inner side of the side portion and is located on a side of the buckle close to the first end of the side portion; A slot is provided on the outer side of the shell body, at least a portion of the buckle is embedded in the slot, and the first flexible seal is extruded between the outer surface of the buckle and the inner surface of the slot. In the circumferential direction of the side, the buckle, the slot and the first flexible seal are all closed ring structures.

[0006] The embodiment of the present application discloses an electronic device, wherein the side of the frame is arranged around the outer periphery of the shell body, and the first end of the side is sealed and connected to the back cover, and in the frame, the buckle is connected to the inner side of the second end of the side, and the antenna is installed on the inner side of the side and is located on the side of the buckle close to the first end of the side. In this case, by forming a sealed connection relationship between the second end of the side and the shell body, it can be ensured that the antenna can be isolated from the outside of the electronic device. To this end, in the embodiment of the present application, a card slot is also provided on the outer side of the shell body, at least a part of the buckle is embedded in the card slot, and by sandwiching the first flexible seal between the outer surface of the buckle and the inner surface of the card slot, and in the circumferential direction of the side, the buckle, the card slot and the first flexible seal are all closed annular structures, so that the buckle and the card slot can form a good annular sealing state, thereby ensuring that the antenna can be isolated from the space outside the electronic device, so that the service life of the antenna is relatively long.

[0007] In addition, in the embodiment of the present application, since the buckle, the slot and the first flexible sealing member are all annular structures, a relatively stable fixed assembly relationship can be formed between the buckle and the slot. In this case, there is no need to form a bonding relationship between the shell body and the frame through connecting members such as double-sided tape. For this reason, in the embodiment of the present application, the antenna installed on the frame is no longer connected to the double-sided tape, and thus, in the process of disassembling the frame, it can be prevented from being damaged by the bonding relationship between the double-sided tape connecting the frame and the shell body and the antenna.

[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0011] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The present application embodiment discloses an electronic device, which may be a mobile phone or a tablet computer, etc., which is not limited in this document. Figure 1 and Figure 2 As shown, the electronic device includes a frame 100, a shell body 200, a back cover 300, a first flexible seal 410 and an antenna 500. Of course, the electronic device also includes other devices such as a battery 720 and a camera module, which will not be introduced one by one here for the sake of brevity.

[0013] Among them, the frame 100 and the shell body 200 are formed separately, and the two can be collectively referred to as the side shell of the electronic device. The frame 100 includes a side portion 110 and a buckle 120, and the side portion 110 is arranged around the outer periphery of the shell body 200, that is, the side portion 110 is a closed ring structure, the first end of the side portion 110 is sealed and connected to the back cover 300, and the buckle 120 is connected to the inner side of the second end of the side portion 110. At the same time, in the embodiment of the present application, the antenna 500 is installed on the inner side of the side portion 110 and is located on the side of the buckle 120 close to the first end of the side portion 110. In this case, by forming a sealed connection relationship between the second end of the side portion 110 and the shell body 200, it can be ensured that the antenna 500 installed on the side portion 110 can be isolated from the outside of the electronic device, thereby ensuring that impurities such as water vapor and dust will not enter through the gap between the side portion 110 and the shell body 200, thereby ensuring that the service life of the antenna 500 is relatively high.

[0014] As described above, a buckle 120 is provided on the inner side of the second end of the side portion 110. For this reason, in the embodiment of the present application, a slot is provided on the outer side of the shell body 200. By embedding at least a portion of the buckle 120 in the slot, and in the embodiment of the present application, the first flexible seal 410 is extruded and disposed between the outer surface of the buckle 120 and the inner surface of the slot, the purpose of sealing the gap between the buckle 120 and the slot by the first flexible seal 410 is achieved. Specifically, the first flexible seal 410 can be a rubber structural member, that is, the first flexible seal 410 can be formed by a rubber material, and the specific parameters such as the size of the first flexible seal 410 can be flexibly determined according to the actual sizes of the buckle 120 and the slot.

[0015] Of course, in order to ensure a high reliability of the sealing relationship, in the circumferential direction of the side portion 110, the buckle 120, the slot and the first flexible seal 410 are all closed annular structures, so that the first flexible seal 410 can provide an annular sealing effect, ensuring that the antenna 500 installed on the inner side of the side portion 110 is relatively well isolated from the outside of the electronic device, and preventing impurities such as water vapor and dust from entering through the gap between the side portion 110 of the frame 100 and the shell body 200, thereby causing damage or failure to the antenna 500 of the electronic device. It should be noted that at any position of the buckle 120 in the circumferential direction of the side portion 110, at least a portion is embedded between the corresponding positions of the slot.

[0016] In addition, in the embodiment of the present application, as described above, at least a portion of the buckle 120 is embedded in the slot, which enables the two to limit each other in the thickness direction of the electronic device. At the same time, since the buckle 120 and the slot are both closed ring structures, in this case, the limiting effect between the frame 100 and the shell body 200 is also relatively better, thereby achieving the purpose of preventing the frame 100 and the shell body 200 from floating up as a whole, so as to prevent the frame 100 and the shell body 200 from warping and other problems.

[0017] The embodiment of the present application discloses an electronic device, in which the side portion 110 of the frame 100 is arranged around the outer periphery of the shell body 200, and the first end of the side portion 110 is sealed and connected to the back cover 300. In the frame 100, the buckle 120 is connected to the inner side of the second end of the side portion 110. By installing the antenna 500 on the inner side of the side portion 110 and being located on the side of the buckle 120 close to the first end of the side portion 110, in this case, by forming a sealed connection relationship between the second end of the side portion 110 and the shell body 200, it can be ensured that the antenna 500 can be isolated from the outside of the electronic device. To this end, in the embodiment of the present application, a slot is further provided on the outer side of the shell body 200, and at least a portion of the buckle 120 is embedded in the slot, and the first flexible seal 410 is clamped between the outer surface of the buckle 120 and the inner surface of the slot, and in the circumferential direction of the side 110, the buckle 120, the slot and the first flexible seal 410 are all closed ring structures, thereby ensuring that the buckle 120 and the slot can form a good annular sealing state, thereby ensuring that the antenna 500 can be isolated from the space outside the electronic device, so that the service life of the antenna 500 is relatively long.

[0018] In addition, in the embodiment of the present application, since the buckle 120, the slot and the first flexible seal 410 are all annular structures, a relatively stable fixed assembly relationship can be formed between the buckle 120 and the slot. In this case, there is no need to form a bonding relationship between the shell body 200 and the frame 100 through connecting parts such as double-sided tape. For this reason, in the embodiment of the present application, the antenna 500 installed on the frame 100 is no longer connected to the double-sided tape, and thus in the process of disassembling the frame 100, it can be prevented from being damaged by the bonding relationship between the double-sided tape connecting the frame 100 and the shell body 200 and the antenna 500.

[0019] In the above embodiment, the first flexible seal 410 is sandwiched between the buckle 120 and the card slot. Optionally, the first flexible seal 410 is located on the inner side of the buckle 120 as a whole. Intuitively speaking, the first flexible seal 410 can be located at the bottom of the card slot, and at least a portion of the buckle 120 extends from the notch of the card slot and is embedded in the card slot. Based on the depth of the card slot, by setting the embedded depth of the buckle 120 and the size of the first flexible seal 410 and other parameters, it can be ensured that the buckle 120 can form an extrusion fit relationship with the first flexible seal 410, and ensure that the first flexible seal 410 can provide a good sealing effect for the buckle 120 and the card slot. Of course, in the embodiment of the present application, in order to improve the stability of the fixed assembly relationship between the buckle 120 and the card slot, the buckle 120 can be made to form an interference fit relationship with the card slot.

[0020] In another embodiment of the present application, in the thickness direction of the back cover 300, the first flexible seal 410 can be located on the side of the buckle 120 facing the back cover 300, which makes the gap between the first flexible seal 410 and the antenna 500 relatively shorter, thereby providing a sealing effect for the antenna 500 from a position close to the antenna 500, ensuring that the reliability of the isolation relationship between the antenna 500 and the outside of the electronic device is relatively stronger. In the embodiment of the present application, intuitively speaking, the antenna 500 is located on the side of the first flexible seal 410 facing the back cover 300, and the buckle 120 is located on the side of the first flexible seal 410 away from the back cover 300.

[0021] As described above, the first flexible seal 410 is extruded between the buckle 120 and the card slot, and during the process of assembling the electronic device, at least a portion of the buckle 120 extends into the card slot. In order to prevent the first flexible seal 410 from rolling and misaligning during the assembly process, in a specific embodiment of the present application, a limiting groove can be formed on the side surface of the card slot facing the first flexible seal 410, and a portion of the first flexible seal 410 is embedded in the limiting groove.

[0022] Considering that the card slot is recessed and arranged on the outer surface of the shell body 200, and further, in order to facilitate the formation of the above-mentioned limiting groove, in a specific embodiment of the present application, a first limiting groove can be arranged on the side surface of the buckle 120 facing the first flexible seal 410, and a part of the first flexible seal 410 is embedded in the first limiting groove, so that during the assembly process, a part of the first flexible seal 410 can be embedded in the first limiting groove first, and then the assembly process between the buckle 120 and the card slot is completed. In addition, glue can also be applied in the first limiting groove to make the relative fixed relationship between the first flexible seal 410 and the buckle 120 more reliable, so as to maximize the prevention of the rolling dislocation of the first flexible seal 410 during the assembly process of the buckle 120.

[0023] In order to further improve the sealing reliability and continuity of the space surrounded by the back cover 300, the frame 100 and the shell body 200, and where the antenna 500 is located, optionally, in the thickness direction of the back cover 300, a second flexible seal 420 can be further extruded and arranged between the side surface of the buckle 120 away from the back cover 300 and the inner surface of the card slot, and in the circumferential direction of the side portion 110, the second flexible seal 420 is also a closed ring structure, so that the sealing effect of the first flexible seal 410 on the space where the antenna 500 is located is further strengthened by a double sealing method, and the isolation relationship between the antenna 500 and the outside of the electronic device is further ensured to be more reliable. That is, in the embodiment of the present application, the first flexible seal 410 and the second flexible seal 420 are respectively arranged on the side of the buckle 120 facing the back cover 300 and the side of the buckle 120 away from the back cover 300.

[0024] As described above, the second flexible seal 420 is also extruded between the buckle 120 and the slot. Furthermore, in order to prevent the second flexible seal 420 from rolling and misaligning during the assembly process, in a specific embodiment of the present application, a limiting groove can be formed on the side surface of the slot facing the second flexible seal 420, and a portion of the second flexible seal 420 is embedded in the aforementioned limiting groove.

[0025] Considering that the card slot is recessed and arranged on the outer surface of the shell body 200, and further, in order to facilitate the formation of the above-mentioned limiting groove, in a specific embodiment of the present application, a second limiting groove can be arranged on the side surface of the buckle 120 facing the second flexible seal 420, and a part of the second flexible seal 420 is embedded in the second limiting groove, so that during the assembly process, a part of the second flexible seal 420 can be embedded in the second limiting groove first, and then the assembly process between the buckle 120 and the card slot is completed. In addition, glue can also be applied in the second limiting groove to make the relative fixed relationship between the second flexible seal 420 and the buckle 120 more reliable, so as to maximize the prevention of the rolling dislocation of the second flexible seal 420 during the assembly process of the buckle 120.

[0026] In order to further facilitate the assembly of the first flexible seal 410 and the second flexible seal 420, in a specific embodiment of the present application, the first flexible seal 410 and the second flexible seal 420 can also be connected to each other on the side facing away from the side 110. Of course, the aforementioned structure for connecting the first flexible seal 410 and the second flexible seal 420 can be called a bridging structure, which can be a closed ring structure in the circumferential direction of the side 110, or the number of the aforementioned bridging structures can be multiple, and they are uniformly and spaced along the circumferential direction of the side 110, which can ensure that the first flexible seal 410 and the second flexible seal 420 can form a stable connection relationship, and during the assembly process, the first flexible seal 410 and the second flexible seal 420 can be installed together outside the buckle 120, thereby reducing the difficulty of assembling the entire electronic device.

[0027] As described above, the first end of the side portion 110 of the frame 100 forms a sealed connection with the back cover 300. Optionally, by applying glue in a ring, the first end of the side portion 110 and the back cover 300 can form a sealed connection while forming a fixed connection. In another embodiment of the present application, a connection structure such as a double-sided adhesive tape can be used to form a fixed and sealed relationship between the first end of the side portion 110 and the back cover 300, so that in the process of disassembling the electronic device, the adhesive force of the double-sided adhesive tape can be greatly reduced by heating, so as to facilitate the disassembly work.

[0028] Based on this, in order to ensure that both the frame 100 and the back cover 300 have installation positions for the double-sided tape, in a specific embodiment of the present application, the frame 100 can include a connecting portion 130, the connecting portion 130 is connected to the inner side of the first end of the side portion 110, and the connecting portion 130 is sandwiched between the back cover 300 and the shell body 200. In this case, the frame 100 can be used to carry the double-sided tape through the connecting portion 130. In detail, in the embodiment of the present application, the connecting portion 130 and the back cover 300 are fixed and sealed by the first adhesive layer 610, and in the circumferential direction of the side portion 110, the connecting portion 130 and the first adhesive layer 610 are both closed annular structures, thereby ensuring that an annular sealing relationship can be formed between the back cover 300 and the connecting portion 130. Among them, the first adhesive layer 610 can specifically be a double-sided tape.

[0029] As described above, the antenna 500 is disposed on the inner side of the side portion 110, and the antenna 500 is located on the side of the buckle 120 close to the first end of the side portion 110. In the embodiment of the present application, Figure 2 As shown, the antenna 500 can be extended from the inner side of the side portion 110 to the connecting portion 130, and by further extending the antenna 500 to the side surface of the connecting portion 130 facing the back cover 300, the installation area of ​​the antenna 500 can be greatly increased, and the frequency band and other parameters of the antenna 500 can also be increased accordingly, thereby greatly improving the radiation performance of the antenna 500. Of course, in order to prevent the first adhesive layer 610 from damaging the antenna 500 during the disassembly of the electronic device, in the embodiment of the present application, the portion of the antenna 500 extending from the side surface of the connecting portion 130 facing the back cover 300 is also located as a whole on the inner side of the first adhesive layer 610, so that the first adhesive layer 610 will not form an adhesion relationship with the antenna 500 while providing a good sealing effect for the antenna 500, thereby preventing the antenna 500 from being damaged during the disassembly of the electronic device.

[0030] As described above, the frame 100 includes the side portion 110, and the connecting portion 130 and the buckle 120 both connected to the inner side of the side portion 110. Optionally, the side portion 110, the connecting portion 130 and the buckle 120 are connected by separate molding, and the connecting portion 130 and the buckle 120 can form a reliable fixed connection relationship with the side portion 110 through a connector, bonding or thermal fusion. In another embodiment of the present application, the side portion 110, the connecting portion 130 and the buckle 120 can also be formed in an integral molding manner, that is, the frame 100 is an integrally molded structural member, which can further improve the reliability of the fixed relationship between the connecting portion 130 and the buckle 120 and the side portion 110, and can reduce the difficulty of processing the frame 100.

[0031] When the back cover 300 is fixed and sealed to the connecting part 130 of the frame 100 by the first adhesive layer 610, in order to further improve the assembly reliability between the back cover 300 and the frame 100, the first end of the side portion 110 can also be extended to the side of the connecting part 130 away from the buckle 120 in the thickness direction of the back cover 300, and the back cover 300 and the side portion 110 can be limited and matched in a direction perpendicular to the thickness direction of the back cover 300. Moreover, in this embodiment, the installation of the back cover 300 is also facilitated. Specifically, during the process of assembling the back cover 300 and the frame 100, since the first end of the side portion 110 protrudes outside the connecting portion 130, the frame 100 forms a structure for accommodating and limiting the back cover 300. Therefore, during the process of assembling the back cover 300, the first adhesive layer 610 can be first bonded to the back cover 300 or the connecting portion 130, and then the back cover 300 can be embedded between the structure surrounded by the connecting portion 130 and the side portion 110, thereby ensuring that the installation position of the back cover 300 is highly accurate.

[0032] In addition, during the process of forming the frame 100, it is also necessary to limit the size of the portion of the first end of the side portion 110 extending out of the connection portion 130 according to the thickness of the back cover 300, so as to prevent the first end of the side portion 110 from still extending out of the side of the back cover 300 away from the connection portion 130 after the back cover 300 is fixedly connected to the connection portion 130. That is, in the embodiment of the present application, the first end of the side portion 110 is lower than or flush with the surface of the side of the back cover 300 away from the connection portion 130.

[0033] As for the frame 100 and the shell body 200, as described above, the two can form a limited matching relationship in the thickness direction of the back cover 300 through the buckle 120 and the slot. In the case where the frame 100 includes the above-mentioned connecting portion 130, in order to further limit the matching stability of the two, the shell body 200 can be provided with a limited step portion, and the limited step portion includes a first limited surface and a second limited surface connected to each other, wherein in the thickness direction of the back cover 300, the second end of the side portion 110 is limited to the first limited surface, and in the direction perpendicular to the thickness direction of the back cover 300, the inner surface of the side portion 110 is limited to the second limited surface. That is, in the embodiment of the present application, the first limited surface is set toward the back cover 300, the second limited surface is located between the first limited surface and the back cover 300, and the second limited surface faces the outside of the shell body 200.

[0034] As described above, the electronic device may also include other structures. For example, the electronic device includes a display module 710, and the display module 710 may form an assembly relationship with the shell body 200. Specifically, the display module 710 is located on the side of the shell body 200 away from the back cover 300, and the display module 710 may be fixed and sealed to the shell body 200 through the second adhesive layer 620. In the circumferential direction of the side portion 110, the second adhesive layer 620 is a closed ring structure to ensure that a reliable sealing fit relationship can be formed between the display module 710 and the shell body 200, so as to prevent impurities such as water vapor and dust from entering the interior of the electronic device from the gap between the display module 710 and the shell body 200. Specifically, the second adhesive layer 620 may also be a double-sided adhesive.
