Description

Technical Field

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

[0002] In related technologies, the frame of an electronic device is usually composed of an inner frame and an outer frame. In some scenarios, the inner frame and the outer frame need to be electrically connected in a specific area in order to transmit signals through the inner frame to the relevant electrical structures deployed in the outer frame.

[0003] In related technologies, the inner and outer frames are typically electrically connected via welded joints located at specific positions. However, due to limitations in industry manufacturing processes, there is a risk of cracking at these welded joints. When cracks occur at the welded joint, the electrical connection at that joint is prone to failure. Therefore, in related technologies, the electrical connection between the inner and outer frames is susceptible to failure. Utility Model Content

[0004] This application provides a frame and an electronic device that can solve the problem of easy failure of the electrical connection between the inner frame and the outer frame in related technologies.

[0005] In a first aspect, a frame is provided, including an inner frame and an outer frame, the outer frame surrounding the inner frame, and the outer frame including a first connecting position, the inner frame including a second connecting position opposite to the first connecting position, the first connecting position and the second connecting position being fixedly connected.

[0006] The first connection position has a first protrusion and a first region at one end facing the second connection position. The first protrusion is a protrusion that extends toward the second connection position relative to the plane where the first region is located. The second connection position has a second protrusion and a second region at one end facing the first connection position. The second protrusion is a protrusion that extends toward the first connection position relative to the plane where the second region is located.

[0007] The first protrusion is disposed opposite to the second region and is electrically connected to the second region, and the second protrusion is disposed opposite to the first region and is electrically connected to the first region.

[0008] In a second aspect, an electronic device is provided, including the housing described in the first aspect.

[0009] In this embodiment, by electrically connecting the first protrusion to the second region and the second protrusion to the first region, two electrical connection points exist between the first and second connection positions. Since the first protrusion extends towards the second connection position relative to the plane of the first region, and the second protrusion extends towards the first connection position relative to the plane of the second region, the two electrical connection positions are staggered. This reduces the risk of simultaneous failure of both electrical connection points due to partial frame breakage. Therefore, if one of the two electrical connection points fails due to partial frame breakage, the first and second connection positions can be electrically connected through the other connection point, thus ensuring a stable electrical connection between the first and second connection positions and improving the stability of the electrical connection between the inner and outer frames.

The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0018] The following description, in conjunction with the accompanying drawings, details a frame and electronic device provided in this application through some embodiments and application scenarios.

[0019] Please see Figures 1 to 6 This application provides a frame, including an inner frame 100 and an outer frame 200. The outer frame 200 is disposed around the inner frame 100, and the outer frame 200 includes a first connection position 210. The inner frame 100 includes a second connection position 110 opposite to the first connection position 210. The first connection position 210 and the second connection position 110 are fixedly connected.

[0020] The first connection position 210 has a first protrusion 211 and a first region 212 at one end facing the second connection position 110. The first protrusion 211 is a protrusion that extends toward the second connection position 110 relative to the plane where the first region 212 is located. The second connection position 110 has a second protrusion 111 and a second region 112 at one end facing the first connection position 210. The second protrusion 111 is a protrusion that extends toward the first connection position 210 relative to the plane where the second region 112 is located.

[0021] The first protrusion 211 is disposed opposite to the second region 112 and is electrically connected to the second region 112. The second protrusion 111 is disposed opposite to the first region 212 and is electrically connected to the first region 212.

[0022] The aforementioned frame can be applied to various types of electronic devices, such as mobile phones, watches, virtual reality (VR) headsets, laptops, tablets, and other electronic products.

[0023] It is understood that both the inner frame 100 and the outer frame 200 are frame structures made of conductive material. For example, in some embodiments of this application, the outer frame 200 is a metal part processed by Computer Numerical Control (CNC), and the outer frame 200 undergoes surface treatment and can also serve as an antenna radiator. The inner frame 100 can be a die-cast metal part.

[0024] In some embodiments of this application, the frame area in the outer frame 200 connected to the first connection position 210 is an antenna radiator. When the frame is applied to an electronic device, the relevant antenna circuit inside the electronic device can be electrically connected to the antenna radiator in sequence through the inner frame 100, the second connection position 110, and the first connection position 210 to realize the signal transmission and reception of the antenna.

[0025] Please see Figure 1 In some embodiments of this application, the first connecting position 210 can be a protruding area protruding from the inside of the outer frame 200 towards the inner frame 100, and the second connecting position 110 can be a protruding area protruding from the outside of the inner frame 100 towards the outer frame 200. The first protrusion 211 and the first area 212 can together form a stepped position, and the second protrusion 111 and the second area 112 can together form a stepped position. These two stepped positions are aligned. The second protrusion 111 can extend towards the first area 212 until it is in contact with the first area 212, or the second protrusion 111 can extend towards the first area 212 until there is a small gap between it and the first area 212. Correspondingly, the first protrusion 211 can extend towards the second area 112 until it is in contact with the second area 112, or the first protrusion 211 can extend towards the second area 112 until there is a small gap between it and the second area 112. The side of the first protrusion 211 may be positioned opposite to the side of the second protrusion 111.

[0026] Since the first protrusion 211 and the second protrusion 111 are adjacent in position, they can be arranged along the thickness direction of the frame, or the first protrusion 211 and the second protrusion 111 can be arranged along the length or width direction of the frame.

[0027] The electrical connection between the first protrusion 211 and the second region 112 can be achieved by welding or by using conductive paste. Similarly, the electrical connection between the second protrusion 111 and the first region 212 can be achieved by welding or by using conductive paste.

[0028] It should be noted that in the above frame, the first connection position 210 and the second connection position 110 are arranged in pairs to form an electrical connection position between the outer frame 200 and the inner frame 100. The number and distribution of the electrical connection positions in the frame can be set as needed.

[0029] In this embodiment, by electrically connecting the first protrusion 211 to the second region 112 and the second protrusion 111 to the first region 212, two electrical connection positions exist between the first connection position 210 and the second connection position 110. Since the first protrusion 211 extends towards the second connection position 110 relative to the plane of the first region 212, and the second protrusion 111 extends towards the first connection position 210 relative to the plane of the second region 112, the two electrical connection positions are staggered. This reduces the risk of simultaneous failure of both electrical connection positions due to partial frame breakage. Therefore, when one of the two electrical connection positions fails due to partial frame breakage, the first connection position 210 and the second connection position 110 can be electrically connected through the other connection position, thus ensuring a stable electrical connection between the first connection position 210 and the second connection position 110, and consequently improving the stability of the electrical connection between the inner frame 100 and the outer frame 200.

[0030] Optionally, the first protrusion 211 and the second protrusion 111 are arranged along the thickness direction of the frame.

[0031] In this embodiment, by arranging the first protrusion 211 and the second protrusion 111 along the thickness direction of the frame, the two welding positions of the first connection position 210 and the second connection position 110 can be staggered relative to each other in the thickness direction of the frame. Since cracks in the frame usually do not penetrate the entire thickness space of the frame, the risk of cracks appearing at both welding positions can be further reduced, thereby helping to further improve the stability of the electrical connection between the first connection position 210 and the second connection position 110.

[0032] Optionally, please see Figure 1 The first protrusion 211 and the second region 112 have a first gap 500, and the first protrusion 211 is welded to the second region 112 through the first gap 500.

[0033] The second protrusion 111 has a second gap 600 between it and the first region 212, and the second protrusion 111 is welded to the first region 212 through the second gap 600.

[0034] Understandably, in Figure 1 In the illustrated embodiment, the first gap 500 and the second gap 600 serve as two weld seams to achieve welding at corresponding positions. Specifically, during the welding process, molten solder can be filled into the first gap 500 and the second gap 600. After the solder solidifies, the solder in the first gap 500 can achieve a fixed connection between the first protrusion 211 and the second region 112, and also achieve electrical conductivity between the first protrusion 211 and the second region 112. Correspondingly, the solder in the second gap 600 can achieve a fixed connection between the second protrusion 111 and the first region 212, and also achieve electrical conductivity between the second protrusion 111 and the first region 212.

[0035] Please see further. Figure 1 ,exist Figure 1 In the illustrated embodiment, the first protrusion 211 and the second protrusion 111 are arranged along the thickness direction of the frame, and the first gap 500 between the first protrusion 211 and the second region 112 can serve as the reverse weld of the frame; the second gap 600 between the second protrusion 111 and the first region 212 can serve as the front weld. When the frame is applied to an electronic device, the front weld can be located on the side of the frame facing the display end face, and the reverse weld can be located on the side of the frame facing the back cover.

[0036] Accordingly, in some other embodiments of this application, the first gap 500 between the first protrusion 211 and the second region 112 can also be used as the front weld of the frame; the second gap 600 between the second protrusion 111 and the first region 212 can also be used as the back weld, which can be set as needed.

[0037] Please see Figure 1 ,exist Figure 1 In the embodiment shown, the two welding positions corresponding to the first gap 500 and the second gap 600 are staggered, so they can mutually enhance each other's ability to resist external forces. Moreover, the two are connected in parallel in the circuit. When a crack occurs at the welding position of one of the welds, the welding position of the other weld can serve as an electrical connection, thereby continuing the electrical connection between the first connection position 210 and the second connection position 110.

[0038] In this embodiment, a first gap 500 is provided between the first protrusion 211 and the second region 112, and the first protrusion 211 is welded to the second region 112 through the first gap 500; a second gap 600 is provided between the second protrusion 111 and the first region 212, and the second protrusion 111 is welded to the first region 212 through the second gap 600. Thus, the welding at the first gap 500 and the welding at the second gap 600 can achieve both a fixed connection between the first connection position 210 and the second connection position 110, and an electrical connection between the first connection position 210 and the second connection position 110.

[0039] Optionally, please see Figure 3 There is a first gap 500 between the first protrusion 211 and the second region 112, and the first gap 500 is filled with a first conductive paste layer 700. The first protrusion 211 is electrically connected to the second region 112 through the first conductive paste layer 700.

[0040] The second protrusion 111 has a second gap 600 between it and the first region 212, and the second protrusion 111 is welded to the first region 212 through the second gap 600.

[0041] The first conductive paste layer 700 can be any kind of electrical contact conductive paste, specifically a high-temperature resistant paste-like conductive material, and the first conductive paste layer 700 can be wrapped inside the frame.

[0042] In some embodiments of this application, the first gap may be a closed gap inside the frame. In other embodiments of this application, the first gap and the second gap are located within the same closed space inside the frame. This prevents the first conductive paste layer 700 from flowing out of the frame.

[0043] In this embodiment, by creating a first gap 500 between the first protrusion 211 and the second region 112, and filling the first gap 500 with a first conductive paste layer 700, the first protrusion 211 is electrically connected to the second region 112 through the first conductive paste layer 700. Thus, when a crack appears at the connection between the first protrusion 211 and the second region 112, the first conductive paste layer 700 can gradually penetrate into the crack, enabling the overall structure to have the ability to self-repair open-circuit damage, thereby further improving the electrical connection stability between the first connection position 210 and the second connection position 110. Furthermore, by creating a second gap 600 between the second protrusion 111 and the first region 212, and welding the second protrusion 111 to the first region 212 through the second gap 600, the welding at the second gap 600 can achieve both a fixed connection between the first connection position 210 and the second connection position 110, and also an electrical connection between them.

[0044] Optionally, please see Figure 3 The second connection position 110 includes a first side 113 and a second side 114 facing away from each other. The first side 113 and the second side 114 are two sides of the second connection position 110 in the thickness direction. The first side 113 is located on the side of the second region 112 away from the second protrusion 111, and the first side 113 is provided with a first snap-fit ​​groove 115. The first connection position 210 includes a first extension 215 extending along the first side 113. The first extension 215 includes a first snap-fit ​​protrusion 216 that is embedded in the first snap-fit ​​groove 115. The first snap-fit ​​protrusion 216 snaps into the first snap-fit ​​groove 115.

[0045] Please see Figure 3 ,exist Figure 3In the illustrated embodiment, since the first conductive paste layer 700 mainly serves as an electrical connection and is unlikely to serve as a fixed connection between the first protrusion 211 and the second region 112, in order to improve the fixed connection effect between the first protrusion 211 and the region 112, a first snap-fit ​​groove 115 can be provided on the first side 113. The first connection position 210 includes a first extension 215 extending along the first side 113. The first extension 215 includes a first snap-fit ​​protrusion 216 embedded in the first snap-fit ​​groove 115. The first snap-fit ​​protrusion 216 snaps into the first snap-fit ​​groove 115. In this way, the first snap-fit ​​groove 115 and the first snap-fit ​​protrusion 216 can together form a snap-fit ​​connection structure. Due to the limiting effect of the first snap-fit ​​groove 115 on the first snap-fit ​​protrusion 216, the distance between the first protrusion 211 and the second region 112 can be effectively prevented from changing, thereby improving the fixed connection effect between the first protrusion 211 and the region 112.

[0046] The cross-sectional shape and size of the first snap-fit ​​protrusion 216 can be the same as those of the first snap-fit ​​groove 115. This ensures that when the first snap-fit ​​protrusion 216 is embedded in the first snap-fit ​​groove 115, there is no gap between them, preventing the protrusion 216 from moving within the groove. Alternatively, the cross-sectional shape of the first snap-fit ​​protrusion 216 can be the same as that of the first snap-fit ​​groove 115, and the protrusion 216 can be slightly larger than the groove. This allows for an interference fit between the protrusion 216 and the groove, further improving the fixation effect of the groove on the protrusion 216.

[0047] The aforementioned first side 113 can be located on either the front or the back of the frame. The front of the frame refers to the side facing the display screen when the frame is used in an electronic device. The back of the frame is the side facing the back of the electronic device.

[0048] In this embodiment, by providing a first snap-fit ​​groove 115 on the first side 113, and the first connection position 210 including a first extension 215 extending along the first side 113, the first extension 215 including a first snap-fit ​​protrusion 216 embedded in the first snap-fit ​​groove 115, the first snap-fit ​​protrusion 216 snapping into the first snap-fit ​​groove 115, thus effectively preventing changes in the distance between the first protrusion 211 and the second region 112, thereby improving the fixed connection effect between the area where the first protrusion 211 and the second region 112 are located.

[0049] Optionally, the first connection position 210 includes a third side 213 and a fourth side 214 facing away from each other. The third side 213 and the fourth side 214 are two sides of the first connection position 210 in the thickness direction. The third side 213 is located on the side of the first protrusion 211 away from the first region 212, and the third side 213 is provided with a second snap-fit ​​groove. The second connection position 110 includes a second extension extending along the third side 213. The second extension includes a second snap-fit ​​protrusion that is embedded in the second snap-fit ​​groove. The second snap-fit ​​protrusion snaps into the second snap-fit ​​groove.

[0050] Among them, this embodiment is similar to Figure 3 The difference in the illustrated embodiment is that the snap-fit ​​connection structure is moved from the inner frame 100 to the outer frame 200.

[0051] In this embodiment, by providing a second snap-fit ​​groove on the third side 213, and the second connection position 110 including a second extension extending along the third side 213, the second extension including a second snap-fit ​​protrusion embedded in the second snap-fit ​​groove, the second snap-fit ​​protrusion engaging with the second snap-fit ​​groove, thus effectively preventing changes in the distance between the first protrusion 211 and the second region 112, thereby improving the fixed connection effect between the area where the first protrusion 211 and the second region 112 are located.

[0052] Optionally, a first gap 500 is provided between the first protrusion 211 and the second region 112, and the first gap 500 is filled with a first conductive paste layer 700, through which the first protrusion 211 is electrically connected to the second region 112; a second gap 600 is provided between the second protrusion 111 and the first region 212, and the second gap 600 is filled with a second conductive paste layer, through which the second protrusion 111 is electrically connected to the first region 212.

[0053] The first conductive paste layer 700 and the second conductive paste layer can be various electrical contact conductive pastes, specifically high-temperature resistant paste-like conductive materials, and the first conductive paste layer 700 and the second conductive paste layer can be wrapped inside the frame.

[0054] In some embodiments of this application, the first gap can be a closed gap inside the frame. The second gap can also be a closed gap inside the frame. In other embodiments of this application, the first gap and the second gap are located within the same closed space inside the frame. This prevents the first conductive paste layer 700 from flowing out of the frame.

[0055] In this embodiment, by creating a first gap 500 between the first protrusion 211 and the second region 112, and filling the first gap 500 with a first conductive paste layer 700, the first protrusion 211 is electrically connected to the second region 112 through the first conductive paste layer 700. Thus, when a crack appears at the connection between the first protrusion 211 and the second region 112, the first conductive paste layer 700 can gradually penetrate into the crack gap, enabling the overall structure to have the ability to self-repair open circuit damage, thereby further improving the electrical connection stability between the first connection position 210 and the second connection position 110. Furthermore, by creating a second gap 600 between the second protrusion 111 and the first region 212, and filling the second gap 600 with a second conductive paste layer, the second protrusion 111 is electrically connected to the first region 212 through the second conductive paste layer. Thus, when a crack appears at the connection between the second protrusion 111 and the first region 212, the second conductive paste layer can gradually penetrate into the crack gap, enabling the overall structure to have the ability to self-repair open circuit damage, thereby further improving the electrical connection stability between the first connection position 210 and the second connection position 110.

[0056] Optionally, the second connection position 110 includes a first side 113 and a second side 114 facing each other. The first side 113 and the second side 114 are two sides of the second connection position 110 in the thickness direction. The first side 113 is located on the side of the second region 112 away from the second protrusion 111, and the first side 113 is provided with a first snap-fit ​​groove 115, and the second side 114 is provided with a third snap-fit ​​groove.

[0057] The first connection position 210 includes: a first extension 215 extending along the first side 113, and a third extension extending along the second side 114. The first extension 215 includes a first snap-fit ​​protrusion 216 embedded in the first snap-fit ​​groove 115, and the first snap-fit ​​protrusion 216 snaps with the first snap-fit ​​groove 115. The third extension includes a third snap-fit ​​protrusion embedded in the third snap-fit ​​groove, and the third snap-fit ​​protrusion snaps with the third snap-fit ​​groove.

[0058] Since the first conductive paste layer 700 mainly serves an electrical connection function and is not effective in fixing the first protrusion 211 to the second region 112, and similarly, the second conductive paste layer mainly serves an electrical connection function and is not effective in fixing the second protrusion 111 to the first region 212, a snap-fit ​​connection structure can be formed on both the first side surface 113 and the second side surface 114 to achieve fixation of the first connection position 210 and the second connection position 110 on both sides.

[0059] The first snap-fit ​​groove 115 and the first snap-fit ​​protrusion 216 form a snap-fit ​​connection structure located on the first side 113, and the third snap-fit ​​groove and the third snap-fit ​​protrusion can form a snap-fit ​​connection structure located on the second side 114. In this way, the first connection position 210 and the second connection position 110 can be fixed on both sides.

[0060] It should be noted that in the above embodiments, both tenon connection structures are located in the inner frame 100. In other embodiments of this application, the two tenon connection structures in the above embodiments can also be moved to the outer frame 200, that is, a corresponding snap-fit ​​groove is provided in the first connection position 210, and an extension and a snap-fit ​​protrusion are provided in the second connection position 110. Alternatively, in other embodiments of this application, one tenon connection structure can be provided in both the inner frame 100 and the outer frame 200, which can be configured as needed.

[0061] In this embodiment, by making the first connection position 210 include: a first extension 215 extending along the first side 113, and a third extension extending along the second side 114, the first extension 215 includes a first snap-fit ​​protrusion 216 embedded in the first snap-fit ​​groove 115, the first snap-fit ​​protrusion 216 snaps with the first snap-fit ​​groove 115, and the third extension includes a third snap-fit ​​protrusion embedded in the third snap-fit ​​groove, the third snap-fit ​​protrusion snaps with the third snap-fit ​​groove, thus, a fixed connection between the first connection position 210 and both sides of the second connection position 110 can be achieved.

[0062] Optionally, please see Figure 1 and Figure 3The second connecting position 110 includes a first side 113 and a second side 114 facing away from each other. The first connecting position 210 includes a third side 213 and a fourth side 214 facing away from each other. The third side 213 and the fourth side 214 are two sides of the first connecting position 210 in the thickness direction. The first side 113 and the third side 213 are located on the same side of the frame. The second side 114 and the fourth side 214 are located on the same side of the frame.

[0063] The frame also includes a first plastic layer 300 and a second plastic layer 400, the first plastic layer 300 covering the first side 113 and the third side 213, and the second plastic layer 400 covering the second side 114 and the fourth side 214.

[0064] The first plastic layer 300 can be attached to the first side 113 and the third side 213 by nano-injection molding, and correspondingly, the second plastic layer 400 can be attached to the second side 114 and the fourth side 214 by nano-injection molding.

[0065] In this embodiment, by using a first plastic layer 300 and a second plastic layer to cover the connection between the first connection position 210 and the second connection position 110 respectively, the waterproof performance of the connection between the first connection position 210 and the second connection position 110 can be improved.

[0066] It should be noted that the frame provided in this application embodiment can achieve electrical connections between the first connection position 210 and the second connection position 110 on both the front and back sides of the frame, thereby forming a double-sided electrical connection structure. This double-sided electrical connection structure has the effects of simplified structure, optimized manufacturing process, cost savings for the frame, and improved product yield consistency. Compared with the frame in the related art, the frame provided in this application embodiment has at least the following beneficial effects:

[0067] The use of a double-sided electrical connection structure can achieve twice the length of the electrical connection path. Utilizing the characteristics of double-sided electrical connections, seam welds of equal strength can be achieved over shorter lengths.

[0068] No rivet holes or waterproof sealant are needed at the connection between the first connecting position 210 and the second connecting position 110. Instead, the entire plastic surface is used for waterproofing, achieving the same level of waterproofing capability over a narrower width.

[0069] Since no rivetless process is required, the manufacturing process is shortened, and the cost of rivets and processing is reduced.

[0070] This technology solves the problem of insufficient frame strength in related technologies, significantly increasing the connection strength of welded areas. It also addresses the issue of overly complex frame manufacturing processes in related technologies, reducing costs and improving waterproofing.

[0071] The frame provided in this application embodiment can be used in the housing of electronic devices with traditional frame structures, serving as an alternative cost reduction measure and being introduced into already designed products.

[0072] This application also provides an electronic device, which includes the frame described in the above embodiments.

[0073] The aforementioned electronic devices can be of various types, such as mobile phones, watches, VR headsets, laptops, tablets, and other electronic products.

[0074] In this embodiment, since the electronic device includes the frame described in the above embodiments, the electronic device can implement the various processes of the frame in the above embodiments and has the same beneficial effects. To avoid repetition, it will not be described again here.

[0075] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
