Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] In related technologies, electronic devices are assembled by a housing, frame, and back cover to form a space for accommodating electrical components such as the motherboard and battery. Foam is typically placed between the frame and the housing to achieve a seal.

[0003] In actual structures, such as Figure 1 As shown, the antenna of the electronic device is usually arranged on the frame 106'. The antenna usually includes multiple flexible circuit boards 102', that is, the multiple flexible circuit boards 102' are located between the foam 104' and the frame 106'. Thus, at the end of the flexible circuit board 102', due to the thickness difference between the end of the flexible circuit board 102' and the frame 106', the compression of the foam 104' varies in the area near the end of the flexible circuit board 102'. This makes it impossible for the foam 104' to completely and simultaneously adhere to the flexible circuit board 102' and the frame 106'. In other words, the foam 104' cannot fill and be equivalently compressed, thus forming gaps at the end of the flexible circuit board 102', between the frame 106' and the foam 104'. Consequently, the housing 108' and the frame cannot meet the high-level waterproof requirements. Utility Model Content

[0004] This application aims to provide an electronic device that can solve the technical problem in the related art where the thickness difference at the end of the flexible circuit board of the antenna prevents the foam from filling and the equivalent compression causes the shell and frame to fail to meet the high level of waterproofing requirements.

[0005] This application provides an electronic device, including:

[0006] The frame includes a first side and a second side opposite to the first side;

[0007] An antenna assembly, comprising at least one flexible circuit board, at least a portion of which is attached to a first side of a frame;

[0008] A sealing strip is attached to the first side of the flexible circuit board and part of the frame.

[0009] The frame has a filling space, and the projection of the filling space covers the end of at least one flexible circuit board along the direction from the second side to the first side. The filling space is filled with filler, and the filler is in contact with the flexible circuit board, the sealing strip and the frame.

[0010] The electronic device of the embodiment of the present application has the filling space formed on the frame body, and the filler is filled in the filling space, so that the filler is simultaneously attached to the flexible circuit board, the sealing strip and the frame body, so that no gap exists between the flexible circuit board, the sealing strip and the frame body, and the sealing effect between the frame body and the shell of the electronic device is ensured in the case that the frame body is buckled and connected with the shell, and the high-level waterproof requirement is met.

[0030] In some embodiments of the present application, an electronic device is provided, Figure 2 One of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 3 Another of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 4 Another of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 3 A sectional view in the B1-B1 direction is shown; Figure 7 Another of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 3 A local enlarged view of the d region is shown; Figure 8 Another of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 7 Another of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 9 Another of the structural schematic diagrams of the electronic device according to the embodiments of the present application is shown; Figure 3A local enlarged view of the middle e region; Figure 10 A structural schematic view of another perspective of Figure 9 Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in FIG. 1, the electronic device 100 includes a frame 102, the frame 102 including a first side and a second side opposite to the first side; an antenna assembly 104, the antenna assembly 104 including at least one flexible circuit board 106, at least a portion of the flexible circuit board 106 being attached to the first side of the frame 102; a sealing strip 108, the sealing strip 108 being attached to the flexible circuit board 106 and the first side of the frame 102; wherein a filling space 110 is formed on the frame 102, a projection of the filling space 110 covering an end of the at least one flexible circuit board 106 in a direction from the second side to the first side, the filling space 110 being filled with a filler 112, the filler 112 being attached to the flexible circuit board 106, the sealing strip 108 and the frame 102.

[0031] In the embodiments of the present application, the electronic device 100 includes the frame 102, which can be used to be connected to the shell and the back cover to form a receiving space of the electronic device 100, so as to receive the main board, the battery and other electrical components of the electronic device 100 in the receiving space.

[0032] Further, the frame 102 includes the first side and the second side opposite to the first side, and the electronic device 100 further includes the antenna assembly 104, the antenna assembly 104 including the at least one flexible circuit board 106, the flexible circuit board 106 being attached to the first side of the frame 102. In addition, the extending direction of the flexible circuit board 106 is adapted to the shape of the first side of the frame 102, that is, the extending direction of the flexible circuit board 106 is the same as the extending direction of the frame 102. By attaching the flexible circuit board 106 of the antenna assembly 104 to the first side of the frame 102, the extending direction of the frame 102 can be used to increase the radiation range of the antenna assembly 104 and improve the signal sending and receiving effect of the antenna assembly 104. In addition, it should be noted that the frame 102 can further include a side wall perpendicular to the first side and the second side, and the antenna assembly 104 can further include a portion of the flexible circuit board attached to the side wall.

[0033] ​Further, the electronic device 100 further comprises a sealing strip 108, the sealing strip 108 is matched with the shape of the frame 102, and the sealing strip 108 is attached to the flexible circuit board 106 and the first side of the frame 102. That is, the part of the frame 102 with the flexible circuit board 106, and the sealing strip 108 is attached to the flexible circuit board 106, and the part of the frame 102 without the flexible circuit board 106, and the sealing strip 108 is directly attached to the frame 102. It can be understood that the sealing strip can be sealing foam, and the sealing foam has a certain compression amount. By setting the compression amount of the sealing strip 108, the gap between the frame 102 and the shell of the electronic device 100 can be sealed in the case of buckling connection and screwing, so as to prevent the impurities such as water from the outside from entering the accommodation space of the electronic device 100 through the gap between the shell and the frame 102, and causing damage to the electrical elements of the electronic device 100.

[0034] Further, the filling space 110 can be provided on the frame 102, and the projection of the filling space 110 covers at least one end of the flexible circuit board 106 in the direction from the second side of the frame to the first side of the frame. It can be understood that the number of filling spaces 110 can be multiple. In the case of one flexible circuit board 106, two filling spaces 110 can be provided, and the projections of the two filling spaces 110 cover the two ends of the flexible circuit board 106 respectively. In the case of multiple flexible circuit boards 106, the filling spaces 110 can be located at both ends of the plurality of flexible circuit boards 106. At this time, the projections of the filling spaces 110 cover the two end portions of the flexible circuit boards 106 respectively. The filling spaces 110 can also be located between two adjacent flexible circuit boards 106. At this time, the projection of the filling space 110 can cover the ends of the two flexible circuit boards 106.

[0035] Further, the filling space 110 can be filled with a filler 112, and since the projection of the filling space 110 covers the end of the flexible circuit board 106, the filler 112 is attached to the flexible circuit board 106, the sealing strip 108 and the frame 102 at the same time, and specifically can be bonded to the flexible circuit board 106, the sealing strip 108 and the frame 102. By filling the filler 112 in the filling space 110, the end of the flexible circuit board 106 and the sealing strip 108 and the frame 102 can be sealed by the filler 112, so that the gap between the flexible circuit board 106 and the frame 102 and the sealing strip 108 caused by the thickness difference of the end of the flexible circuit board 106 can be effectively avoided.

[0036] That is, compared with the related art, since there is a thickness difference between the end of the flexible circuit board 106 and the frame, a gap is formed between the end of the flexible circuit board 106, the frame, and the foam, and thus the waterproof requirement of a high level (for example, Ingress Protection 65 or Ingress Protection 66) between the shell and the frame cannot be met. By opening the filling space 110 on the frame 102 and filling the filler 112 in the filling space 110, the filler 112 is simultaneously fitted with the flexible circuit board 106, the sealing strip 108, and the frame 102, so that there is no gap between the flexible circuit board 106, the sealing strip 108, and the frame 102, and thus the sealing effect between the frame and the shell is ensured, and the waterproof requirement of a high level is met.

[0037] For example, the filler 112 can be a sealant. When the sealant is in a liquid state, after the frame 102, the flexible circuit board 106, and the sealing strip 108 are assembled, the sealant is filled in the filling space 110, then the sealing strip 108 is placed downward, the sealant is gradually fitted with the flexible circuit board 106, the sealing strip 108, and the frame 102, and finally the sealant is gradually solidified. Finally, the shell of the electronic device and the second side of the frame are fixedly connected, so that the sealant is simultaneously fitted with the flexible circuit board 106, the sealing strip 108, and the frame 102, so that there is no gap between the flexible circuit board 106, the sealing strip 108, and the frame 102, and thus the sealing effect between the frame and the shell is ensured, and the waterproof requirement of a high level is met.

[0038] Alternatively, after the frame 102, the flexible circuit board 106, and the sealing strip 108 are assembled, the shell of the electronic device 100 and the frame 102 are fixedly connected, then the shell is placed downward, and further, the sealant is filled in the filling space 110, and the sealant is gradually solidified. At this time, since the frame 102 and the shell of the electronic device 100 have begun to compress the sealing strip 108, after the sealant is poured, the sealant will not be deformed due to the deformation of the sealing strip, and the sealing effect of the sealant is ensured.

[0039] The electronic device 100 of the embodiment of the present application opens the filling space 110 on the frame 102, and fills the filler 112 in the filling space 110, so that the filler 112 is simultaneously fitted with the flexible circuit board 106, the sealing strip 108, and the frame 102, so that there is no gap between the flexible circuit board 106, the sealing strip 108, and the frame 102, and thus the sealing effect between the frame and the shell of the electronic device 100 is ensured, and the waterproof requirement of a high level is met.

[0040] In some embodiments of the present application,Figure 5 a partial enlarged view of the f region in FIG. 1 is shown, Figure 4 a partial enlarged view of the f region in FIG. 1 is shown, Figure 6 a partial enlarged view of the f region in FIG. 1 is shown, Figure 4 a partial enlarged view of the g region in FIG. 1 is shown, Figure 5 and Figure 6 As shown in

[0041] In the embodiment of the present application, the frame body 102 can include a second side opposite to the first side, and the through hole 114 can be formed along the direction from the first side to the second side, that is, along the thickness direction of the frame body 102, and the through hole 114 is opposite to the end of the flexible circuit board 106, so that the space in the through hole 114 forms the filling space 110.

[0042] It can be understood that the flexible circuit board 106 is attached to the first side of the frame body 102, and the through hole 114 is formed along the direction from the first side to the second side of the frame body 102, so that the space in the through hole 114 forms the filling space 110. In this way, in the assembly process, the flexible circuit board 106 can be first attached to the first side of the frame body 102, and the end of the flexible circuit board 106 is opposite to the through hole 114, and then the sealing strip 108 is attached to the flexible circuit board 106 and part of the first side of the frame body 102. After the frame, the flexible circuit board and the sealing strip are assembled, the filling material 112 is directly filled into the through hole 114 on the second side of the frame body 102, so that the filling material 112 can gradually be attached to the flexible circuit board 106, the sealing strip 108 and the frame body 102, facilitating the assembly process of the frame body 102.

[0043] Alternatively, after the frame body 102, the flexible circuit board 106 and the sealing strip 108 are assembled, the shell of the electronic device 100 is fixedly connected with the frame body 102, and then the shell is placed downward, and further, the filling material is filled into the through hole 114 on the second side of the frame body 102, and the filling material 112 is gradually solidified. At this time, since the frame body 102 and the shell of the electronic device 100 have begun to compress the sealing strip 108, after the filling material 112 is poured, the filling material 112 will not deform due to the deformation of the sealing strip, ensuring the sealing effect of the filling material 112.

[0044] In some embodiments of the present application, as shown in Figure 5 and Figure 6 As shown in

[0045] In the embodiments of the present application, the through hole 114 can be divided into a first hole section 116 and a second hole section 118 in the direction from the first side to the second side, wherein the first hole section 116 is opposite to the end of the flexible circuit board 106, and the first hole section 116 is located between the flexible circuit board 106 and the second hole section 118.

[0046] Further, the cross-sectional area of the first hole section 116 is smaller than the cross-sectional area of the second hole section 118, that is, the second hole section 118 is equivalent to a sink groove extending from the second side of the frame 102 to the first side of the frame 102. For example, in the case where the first hole section 116 and the second hole section 118 are both rectangular, the length and width of the second hole section 118 can be greater than the length and width of the first hole section 116. It should be noted that, in the process of pouring the filler 112 into the filling space 110, due to the process limitation, the pouring amount of the filler 112 has a tolerance fluctuation, and therefore, by setting the second hole section 118, the second hole section 118 serves as a fluctuation space in the pouring process of the filler 112, and at the same time, the second hole section 118 can also serve as a space for visually checking whether the filler 112 is poured in place, thereby ensuring the pouring amount of the filler 112, and further ensuring that the filler 112 can simultaneously fit with the flexible circuit board 106, the sealing strip 108 and the frame 102, so that there is no gap between the flexible circuit board 106, the sealing strip 108 and the frame 102, thereby ensuring the sealing effect between the frame and the shell, and meeting the high-level waterproof requirement.

[0047] In some embodiments of the present application, as shown in Figure 5 and Figure 6 , in the direction from the first side to the second side, the filler 112 fills the entire first hole section 116, and the filler 112 fills a part of the second hole section 118.

[0048] In the embodiments of the present application, in the process of pouring the filler 112 into the through hole 114, in the direction from the first side to the second side, the filler 112 needs to fill the entire first hole section 116, so as to ensure that the filler 112 can simultaneously fit with the flexible circuit board 106, the sealing strip 108 and the frame 102, thereby making the flexible circuit board 106, the sealing strip 108 and the frame 102 without gaps.

[0049] Meanwhile, the filler 112 also needs to fill a part of the second hole section 118, that is, a part of the second hole section 118 close to the first hole section 116, and the filler 112 cannot overflow out of the second hole section 118, that is, the filler 112 cannot reach the second side of the frame 102. In this way, the filler 112 in at least a part of the second hole section 118 can be used as the fluctuation amount of the filler 112 during the filling process of the filler 112, so as to ensure the filling amount of the filler 112, so as to ensure that the filler 112 can fill the whole of the first hole section 116, and thus ensure that the filler 112 can simultaneously fit the flexible circuit board 106, the sealing strip 108 and the frame 102. Meanwhile, the overflow of the filler 112 can also be avoided to pollute other components of the electronic device 100.

[0050] In some embodiments of the present application, as shown in Figure 6 The length of the second hole section 118 in the direction from the first side to the second side is greater than or equal to a first preset value.

[0051] In the embodiments of the present application, the length c of the second hole section 118 in the direction from the first side to the second side of the frame 102, that is, in the thickness direction of the frame 102, can be greater than or equal to a first preset value. Through the setting of the length of the second hole section 118, the size of the space in the second hole section 118, that is, the capacity of the second hole section 118, can be ensured. When filling the filler 112, the filler 112 in the second hole section 118 can be used as the fluctuation amount of the filler 112 during the filling process of the filler 112, so as to ensure the size of the fluctuation amount of the filler 112, and thus ensure the filling amount of the filler 112 in the first hole section 116, so as to ensure that the filler 112 can fill the whole of the first hole section 116.

[0052] Specifically, the first preset value can be set according to the thickness of the frame and the thickness of the flexible circuit board 106, for example, the first preset value can be set to 0.4 mm, 0.5 mm or 0.6 mm, which is not limited in the embodiments of the present application. In order to facilitate the inspection of the amount of the filler in the second hole section.

[0053] In some embodiments of the present application, as shown in Figure 6 The length of the flexible circuit board 106 covered by the projection of the flexible circuit board 106 and the first hole section 116 in the length direction of the flexible circuit board 106 is greater than or equal to a second preset value.

[0054] In the embodiments of the present application, due to the machining tolerance of the end of the flexible circuit board 106 or the assembly tolerance of the flexible circuit board 106, etc., the position of the end of the flexible circuit board 106 may fluctuate in the length direction of the flexible circuit board 106, and therefore, the first hole section 116 needs to cover a sufficient length of the flexible circuit board 106 in the length direction of the flexible circuit board 106, so as to ensure that the filler 112 in the first hole section 116 can be as close as possible to the flexible circuit board 106, and avoid a gap between the filler 112 and the end of the flexible circuit board 106.

[0055] Therefore, the length a of the flexible circuit board 106 covered by the first hole section 116 in the length direction of the flexible circuit board 106 can be greater than or equal to the second preset value, so as to ensure that the filler 112 in the first hole section 116 can be as close as possible to the flexible circuit board 106. Specifically, the second preset value can be 0.6 mm, 0.75 mm, or 0.85 mm, which is not limited in the embodiments of the present application.

[0056] In some embodiments of the present application, as shown in Figure 6 In the case that the projection of the first hole section 116 covers the end of one flexible circuit board 106, the length of the sealing strip 108 covered by the projection of the first hole section 116 in the length direction of the flexible circuit board 106 is greater than or equal to the second preset value.

[0057] In the embodiments of the present application, when the first hole section 116 is opposite to the end of one flexible circuit board 106, in order to ensure that the filler 112 in the first hole section 116 can be as close as possible to the flexible circuit board 106 and the sealing strip 108, the length b of the sealing strip 108 covered by the projection of the first hole section 116 in the length direction of the flexible circuit board 106 is also greater than or equal to the second preset value, so as to ensure the filling effect of the filler 112, and avoid a gap between the filler 112 and the flexible circuit board 106, and between the filler 112 and the sealing strip 108.

[0058] In some embodiments of the present application, as shown in Figure 5 In the case that the projection of the first hole section 116 covers the ends of two flexible circuit boards 106, the distance between the ends of the two flexible circuit boards 106 is greater than or equal to the third preset value.

[0059] In this embodiment of the application, when the projection of the first hole segment 116 simultaneously covers the ends of the two flexible circuit boards 106, in order to ensure that the filler 112 in the first hole segment 116 can fit as tightly as possible with the sealing strip 108 between the ends of the two flexible circuit boards 106, the distance v between the ends of the two flexible circuit boards 106 can be set to be greater than or equal to a third preset value, thereby ensuring the filling effect of the filler 112 and avoiding gaps between the filler 112 and the flexible circuit board 106, and between the filler 112 and the sealing strip 108.

[0060] It is understandable that the tightness of the fit between the filler 112 and the sealing strip 108 is related to the contact area between them. That is, the larger the contact area, the tighter the fit. Therefore, setting the distance between the ends of the two flexible circuit boards 106 to be greater than or equal to a third preset value ensures the contact area between the filler 112 and the sealing strip 108, thereby ensuring the tightness of the fit. Simultaneously, it also prevents the ends of the two flexible circuit boards 106 from overlapping due to material shape tolerances and assembly tolerances.

[0061] Specifically, the third preset value can be set to 0.5mm, 0.6mm or 0.7mm, and this application embodiment does not specifically limit it.

[0062] In some embodiments of this application, such as Figure 7 As shown, along the width direction of the flexible circuit board 106, the width of the first hole segment 116 is greater than or equal to the fourth preset value.

[0063] In this embodiment, the width s of the first hole segment 116 can be set to be greater than or equal to a fourth preset value in the width direction of the flexible circuit board 106. This ensures a tight fit between the filler 112 in the first hole segment 116 and the flexible circuit board 106 and the sealing strip 108. It also facilitates the flow and filling of the filler 112 within the first hole segment 116, thereby ensuring a tight fit between the filler 112 and the flexible circuit board 106 and the sealing strip 108, improving the filling effect of the filler 112 between the flexible circuit board 106 and the sealing strip 108, and preventing gaps between the filler 112 and the flexible circuit board 106, and between the filler 112 and the sealing strip 108.

[0064] Specifically, the fourth preset value can be set to 0.7mm, 0.8mm or 0.9mm, and this application embodiment does not specifically limit it.

[0065] In some embodiments of the present application, the filler 112 comprises a sealant.

[0066] In the embodiments of the present application, the filler 112 can be a sealant, such as a silicone glue, etc. which has fluidity and can be cured after a period of time. It can be understood that the silicone glue has good fluidity, which can be well attached to the flexible circuit board 106, the sealing strip 108 and the frame 102, thereby ensuring the sealing effect. Moreover, the silicone glue can be cured at room temperature after a period of time, thereby ensuring the filling effect of the silicone glue in the normal use process of the electronic device 100.

[0067] In some embodiments of the present application, as shown in Figure 4 The electronic device 100 further comprises a housing 120 connected to the first side of the frame 102, and the sealing strip 108 is located between the housing 120 and the frame 102.

[0068] In the embodiments of the present application, the electronic device 100 further comprises a housing 120 fixedly connected to the first side of the frame 102, that is, when the housing 120 is connected to the first side of the frame 102, the housing 120 and the first side of the frame 102 will compress the sealing strip, that is, the sealing strip 108 is located between the frame 102 and the housing 120, thereby realizing the sealing of the gap between the frame 102 and the housing 120.
