Description

Technical Field

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

[0002] In related technologies, electronic devices typically include a charging port. With repeated plugging and unplugging of the charging port, the frame around the port may become scratched. To prevent this scratching, such as... Figure 9 As shown, a layer of plastic 900 is typically placed on the inner wall of the charging port to protect the metal frame. The plastic 900 covers the entire inner wall of the charging port, allowing the metal plug to rub against the plastic instead of the metal during insertion and removal, thus preventing the anodized layer of the metal frame from being scratched and exposing the metal itself. Because a certain thickness of space needs to be reserved at the charging port for the plastic 900 layer, the overall thickness of the frame is relatively large.

[0003] However, as electronic products become increasingly thinner and lighter, the thickness of the mid-frame is constantly being reduced, while the size of the charging port opening cannot be reduced. This leads to a continuous reduction in the thickness of the mid-frame wall, with the extreme case being only thick enough for a single layer of metal, leaving little room for a layer of plastic. Therefore, many products, in pursuit of extreme thinness, use a pure metal structure for the charging port area, abandoning plastic altogether. This, however, fails to address the issue of the mid-frame at the charging port being easily scratched. Clearly, there is a challenge in these technologies to simultaneously achieve both a thinner and lighter electronic device and prevent scratches on the mid-frame around the charging port. Utility Model Content

[0004] This application provides a frame and an electronic device that can solve the problem in related technologies where it is difficult to simultaneously achieve a thinner and lighter electronic device and avoid the charging port on the middle frame from being easily scratched.

[0005] In a first aspect, an electronic device is provided, including a metal frame with an interface for connecting a cable. Along a first direction, the metal frame includes a reinforcing portion and an extension portion, the thickness of the reinforcing portion being greater than the thickness of the extension portion. The first direction is the insertion direction of the interface.

[0006] The reinforcing part is provided with a groove, and a plastic part is embedded in the groove. The plastic part is located at the insertion end of the interface, and the length of the plastic part in the first direction is less than the length of the reinforcing part in the first direction.

[0007] In this embodiment, since the thickness of the reinforcing portion of the metal frame is greater than that of the extension portion, a groove is provided at the thicker reinforcing portion of the metal frame, and a plastic part is embedded in the groove. That is, the plastic part is only located at the thicker part of the metal frame itself. For the thinner extension portion, there is no need to reserve space for the plastic part. Thus, the plastic part does not require additional space in the metal frame, which is beneficial for the thinner and lighter design of the electronic device. Simultaneously, since the plastic part is located at the insertion end of the interface, during the insertion and removal of the plug relative to the interface, the plug mainly rubs against the plastic part, thereby reducing the risk of the metal frame being scratched during plug insertion and removal. This achieves both a thinner and lighter electronic device and reduces the risk of scratches on the interface of the metal frame. Attached Figure Description

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

[0019] The following description, in conjunction with the accompanying drawings, details an electronic device provided in this application through some embodiments and application scenarios.

[0020] Please see Figures 1 to 8 This application provides an electronic device, including a metal frame 100, on which an interface 300 for connecting cables is provided. Along a first direction, the metal frame 100 includes a reinforcing portion 120 and an extension portion 110, the thickness of the reinforcing portion 120 being greater than the thickness of the extension portion 110. The first direction is the insertion direction of the interface 300.

[0021] The reinforcing part 120 is provided with a groove 301, and a plastic part 200 is embedded in the groove 301. The plastic part 200 is located at the insertion end 302 of the interface 300, and the length of the plastic part 200 in the first direction is less than the length of the reinforcing part 120 in the first direction.

[0022] The aforementioned electronic devices can be common electronic devices such as mobile phones, tablets, computers, and cameras. The aforementioned metal frame 100 can serve as the metal mid-frame of the electronic device.

[0023] The aforementioned interface 300 is an external connection interface for electronic devices. For example, the aforementioned interface 300 can be various Universal Serial Bus (USB) interfaces. The USB female connector in the electronic device can be housed within the interface 300, so that the USB male connector in the external cable can be inserted into the interface 300 and electrically connected to the USB female connector.

[0024] The aforementioned plastic part 200 is an annular plastic part 200 that conforms to the groove wall of the aforementioned groove 301, and the internal space of the plastic part 200 is the first segment 1211 of the aforementioned interface 300. The interface 300 may further include a second segment 1212 extending from the first segment 1211 into the extension portion 110. The inner wall of the first segment 1211 is aligned with the inner wall of the second segment 1212, that is, the inner wall of the plastic part 200 is aligned with the inner wall of the second segment 1212. The aforementioned plastic part 200 may be a plastic part 200 formed directly by injection molding on the aforementioned metal frame 100, or the plastic part 200 may be a plastic part 200 that is connected to the metal frame 100 by an adhesive process after processing.

[0025] Please see Figure 1 The aforementioned reinforcing portion 120 is the edge region of the metal frame 100, and the aforementioned extension portion 110 is the inner region connected to the reinforcing portion 120. The display module of the electronic device can cover one side of the extension portion 110, and the back cover of the electronic device can cover the other side of the extension portion 110. Since the thickness of the reinforcing portion 120 is greater than the thickness of the extension portion 110, the reinforcing portion 120 can protrude a certain size relative to the two end faces of the extension portion 110. In this case, the protrusions of the reinforcing portion 120 relative to the extension portion 110 can be located at the periphery of the display module and the back cover, respectively, to achieve protection of the edges of the display module and the back cover.

[0026] Understandably, please see Figure 3 The groove 301 and the interface 300 can form a stepped hole 121. The stepped hole 121 can be achieved by reducing material along the length of the metal frame 100. During the processing of the stepped hole 121, since the metal thickness of the reinforcing part 120 is relatively large, it is possible to provide a plastic layer inside the metal layer when the reinforcing part 120 has a metal layer. Therefore, the material reduction dimension of the reinforcing part 120 in the thickness direction is the sum of the height of the interface 300 and twice the single layer thickness of the plastic part 200. Accordingly, since the thickness of the extension 110 is relatively thin, in order to achieve the thinning of electronic devices, the thickness of the extension 110 may only be enough to install a single metal piece. Therefore, the reduced thickness of the extension 110 can be the height of the interface 300. In this way, when the plastic part 200 is embedded in the inner wall of the groove 301, the inner wall of the plastic part 200 can be aligned with the inner wall of the second segment 1212, and the inner hole of the plastic part 200 and the second segment 1212 form the interface 300.

[0027] In some embodiments of this application, the thickness of a single layer of the plastic part 200 is greater than or equal to 0.3 mm to avoid damage to the plastic part 200 during plug insertion and removal due to its thinness. Correspondingly, in the aforementioned reinforcing part 120, the thickness of the metal layer stacked with the plastic part 200 is greater than or equal to 0.25 mm to ensure that the reinforcing part 120 has sufficient structural strength.

[0028] The first direction mentioned above refers to the depth direction of the interface 300. When the electronic device is a candybar phone and the interface 300 is located at the bottom of the candybar phone, the first direction refers to the length direction of the candybar phone. The insertion end 302 of the interface 300 refers to the insertion end 302 of the interface 300 located on the outer wall of the metal frame 100.

[0029] In this embodiment, since the thickness of the reinforcing portion 120 of the metal frame 100 is greater than the thickness of the metal extension portion 110, a groove 301 is provided at the thicker reinforcing portion 120 of the metal frame 100, and a plastic part 200 is embedded in the groove 301. That is, the plastic part 200 is only located at the thicker part of the metal frame 100 itself. For the thinner extension portion 110, there is no need to reserve space for the plastic part 200. Thus, the plastic part 200 does not require additional space in the metal frame 100, which is beneficial for the thinner and lighter design of the electronic device. At the same time, since the plastic part 200 is located at the insertion end 302 of the interface 300, during the insertion and removal of the plug relative to the interface 300, the plug mainly rubs against the plastic part 200, thereby reducing the risk of the metal frame 100 being scratched during plug insertion and removal. This achieves both a thinner and lighter electronic device and reduces the risk of scratches on the interface 300 of the metal frame 100.

[0030] Optionally, the groove wall of the groove 301 is provided with a first limiting part, and the outer side wall of the plastic part 200 is provided with a second limiting part. The first limiting part and the second limiting part cooperate to limit the movement of the plastic part 200 toward the insertion end 302.

[0031] The aforementioned first limiting part can be various common limiting structures such as a limiting groove, a limiting protrusion, or a limiting surface. Correspondingly, the second limiting part can be a limiting structure that matches the first limiting part. For example, when the first limiting part is a limiting groove, the second limiting part can be a limiting protrusion that matches the first limiting part, and the limiting protrusion is embedded in the limiting groove. As another example, when the first limiting part is a limiting protrusion, the second limiting part can be a limiting groove that matches the first limiting part, and the limiting protrusion is embedded in the limiting groove. Yet another example, when the first limiting part is a limiting surface, the second limiting part can be a limiting surface that matches the first limiting part, and the two limiting surfaces can fit together.

[0032] In this embodiment, by providing a first limiting part on the groove wall of the groove 301 and a second limiting part on the outer side wall of the plastic part 200, and then making the first limiting part and the second limiting part limit each other, the plastic part 200 can be prevented from moving toward the insertion end 302, thereby preventing the plastic part 200 from detaching from the interface 300.

[0033] Optionally, the groove 301 includes a first inner wall 12113 and a second inner wall 12114, the first inner wall 12113 and the second inner wall 12114 being arranged at intervals along the thickness direction of the metal frame 100;

[0034] The first limiting part includes: a first inclined surface region 126 located in the first inner wall 12113, and a second inclined surface region 127 located in the second inner wall 12114. The first inclined surface region 126 and the second inclined surface region 127 are disposed opposite to each other, and the distance between the first inclined surface region 126 and the second inclined surface region 127 gradually increases along the first direction.

[0035] The second limiting portion includes a third inclined surface region 201 and a fourth inclined surface region 202 located on the outer side wall of the plastic part 200. The third inclined surface region 201 is in contact with the first inclined surface region 126, and the fourth inclined surface region 202 is in contact with the second inclined surface region 127.

[0036] In this embodiment, the first limiting portion includes a first inclined surface region 126 located in the first inner wall 12113 and a second inclined surface region 127 located in the second inner wall 12114. The first inclined surface region 126 and the second inclined surface region 127 are disposed opposite to each other, and the distance between the first inclined surface region 126 and the second inclined surface region 127 gradually increases along the first direction. The second limiting portion includes a third inclined surface region 201 and a fourth inclined surface region 202 located on the outer side wall of the plastic part 200. The third inclined surface region 201 is in contact with the first inclined surface region 126, and the fourth inclined surface region 202 is in contact with the second inclined surface region 127. Thus, under the limiting effect of the first inclined surface region 126 and the second inclined surface region 127 on the plastic part 200, the plastic part 200 cannot move toward the insertion end 302, thereby preventing the plastic part 200 from detaching from the interface 300. The first inclined area 126 and the second inclined area 127 together form an inverted snap-on adhesive structure. Compared with the conventional step and T-groove inverted snap-on adhesive structures, the inclined snap-on adhesive structure provided in this application embodiment can retain more metal wall thickness while achieving the inverted snap-on adhesive function, and is suitable for situations where the metal frame wall thickness is relatively thin.

[0037] Optionally, along the first direction, the first inclined region 126 is inclined in a direction away from the interface 300, and the second inclined region 127 is inclined in a direction away from the interface 300.

[0038] Please see Figure 4 In some embodiments of this application, along the first direction, the first inclined region 126 and the second inclined region 127 are inclined in opposite directions, and along the first direction, the distance between the first inclined region 126 and the second inclined region 127 gradually increases.

[0039] In this embodiment, since the first inclined surface region 126 is inclined away from the interface 300 along the first direction, and the second inclined surface region 127 is inclined away from the interface 300, the first inclined surface region 126 and the second inclined surface region 127 can respectively limit the plastic part 200 from both sides, thereby further improving the limiting effect on the plastic part 200.

[0040] Optionally, the groove 301 further includes a third inner wall 12111 and a fourth inner wall 12112, both of which are located between the first inner wall 12113 and the second inner wall 12114.

[0041] The first limiting part further includes: a first locking groove 130 located on the third inner wall 12111 and a second locking groove 131 located on the fourth inner wall 12112;

[0042] The second limiting part further includes: a first snap-fit ​​protrusion 230 and a second snap-fit ​​protrusion 240 located on the outer side wall of the plastic part 200, wherein the first snap-fit ​​protrusion 230 is snapped into the first snap-fit ​​groove 130 and the second snap-fit ​​protrusion 240 is snapped into the second snap-fit ​​groove 131.

[0043] In this embodiment, the groove 301 includes a first inner wall 12113, a second inner wall 12114, a third inner wall 12111, and a fourth inner wall 12112 connected sequentially. The third inner wall 12111 and the fourth inner wall 12112 are two pairs of inner walls of the groove 301. Figure 8 In the illustrated embodiment, the third inner wall 12111 and the fourth inner wall 12112 are two inner walls in the width direction of the electronic device.

[0044] Please see Figure 8 The first snap-fit ​​protrusion 230 can form a T-shaped adhesive-pulling structure with the main body of the plastic part 200. Correspondingly, the second snap-fit ​​protrusion 240 can form another T-shaped adhesive-pulling structure with the main body of the plastic part 200. The first direction is the width direction of the frame. Since the wall thickness is sufficient in the width direction of the frame, a T-groove adhesive-pulling structure can be used to pull adhesive onto the two side walls of the plastic part 200, thereby improving the reliability of adhesive pulling and reducing processing difficulty.

[0045] In this embodiment, by providing a first snap-fit ​​groove 130 on the third inner wall 12111 and a second snap-fit ​​groove 131 on the fourth inner wall 12112, and by providing a first snap-fit ​​protrusion 230 and a second snap-fit ​​protrusion 240 on the plastic part 200, the first snap-fit ​​protrusion 230 snaps into the first snap-fit ​​groove 130 and the second snap-fit ​​protrusion 240 snaps into the second snap-fit ​​groove 131, the plastic part 200 can be further prevented from detaching from the metal frame 100.

[0046] Optionally, the reinforcing part 120 includes a first wall plate 1213 and a second wall plate 1214 spaced apart along the thickness direction of the metal frame 100. The interface 300 is located between the first wall plate 1213 and the second wall plate 1214. The second wall plate 1214 has a snap-fit ​​groove on the side facing away from the interface 300, and the surface of the second wall plate 1214 facing the groove 301 includes a first region 123 and a second region 124, where the first region 123 and the second region 124 are the groove 301. The inner wall, and a stepped position 125 is formed at the connection between the first region 123 and the second region 124. The orthographic projection of the first region 123 onto the plane where the bottom of the snap-fit ​​groove is located is offset from the position of the bottom of the snap-fit ​​groove. The orthographic projection of the second region 124 onto the plane where the bottom of the snap-fit ​​groove is located overlaps with the position of the bottom of the snap-fit ​​groove at least partially. The distance between the first region 123 and the plane where the bottom of the snap-fit ​​groove is located is less than the distance between the second region 124 and the plane where the bottom of the snap-fit ​​groove is located.

[0047] The inner walls of the first wall panel 1213 and the second wall panel 1214 form two inner walls in the thickness direction of the stepped hole 121. The aforementioned snap-fit ​​groove can be a recess 301 for snapping into the back cover of an electronic device. For example, the inner wall of the back cover can include a snap-fit ​​protrusion. During the assembly of the electronic device, the snap-fit ​​protrusion of the back cover can be embedded into the aforementioned snap-fit ​​groove to achieve a fixed connection between the back cover and the frame.

[0048] The formation of a stepped position 125 at the connection between the first region 123 and the second region 124 means that the first region 123 and the second region 124 are not on the same plane, so that a stepped position 125 is formed at the connection between the first region 123 and the second region 124.

[0049] The fact that the first region 123 is positioned opposite to the bottom of the slot in the plane of the slot means that there is no overlap between the first region 123 and the bottom of the slot, that is, the slot does not extend below the first region 123.

[0050] Accordingly, the fact that the orthographic projection of the second region 124 onto the plane where the bottom of the snap-fit ​​groove is located overlaps with the bottom of the snap-fit ​​groove means that there is an overlapping area between the orthographic projection of the second region 124 onto the plane where the bottom of the snap-fit ​​groove is located and the bottom of the snap-fit ​​groove, that is, the snap-fit ​​groove extends below the second region 124.

[0051] Please see Figure 4The distance between the first region 123 and the plane where the bottom of the slot is located is less than the distance between the second region 124 and the plane where the bottom of the slot is located means that the first region 123 is sunken relative to the second region 124 to form a sunken step at the connection between the first region 123 and the second region 124, wherein the sunken step is the aforementioned step 125.

[0052] It is understood that the shape of the outer wall of the plastic part 200 matches the structural shape of the second wall panel 1214 facing the first segment 1211. That is, the surface of the plastic part 200 on the side opposite to the second wall panel 1214 can have a step that matches the stepped position 125, to ensure that the plastic part 200 is simultaneously attached to the first region 123 and the second region 124. In other words, the thickness of the plastic part 200 at the first region 123 is greater than its thickness at the second region 124.

[0053] Please see Figure 4 The second region 124 and the first inclined region 126 mentioned above are the same region.

[0054] In this embodiment, since the second wall panel 1214 is provided with a snap-fit ​​groove, and the wall thickness of the second wall panel 1214 at the snap-fit ​​groove is insufficient, in order to ensure that the plastic at the opening of the interface 300 has sufficient thickness, and to ensure that the second wall panel 1214 has sufficient metal wall thickness at the snap-fit ​​groove, this embodiment of the application incorporates a recessed step design at the opening of the second wall panel 1214, even though the distance between the first region 123 and the plane where the bottom of the snap-fit ​​groove is located is less than the distance between the second region 124 and the plane where the bottom of the snap-fit ​​groove is located. Thus, because the second wall panel 1214 is recessed at the opening, it helps to ensure that the plastic at the opening of the interface 300 has sufficient thickness space, ensuring that the plastic at the opening has sufficient thickness. Correspondingly, there is no recess at the snap-fit ​​groove, ensuring that the snap-fit ​​groove has sufficient metal wall thickness.

[0055] Optionally, the plastic part 200 includes a first sidewall 210 and a second sidewall 220 disposed opposite to each other, the first sidewall 210 and the second sidewall 220 being spaced apart along the thickness direction of the metal frame 100;

[0056] The dimension of the first sidewall 210 along the first direction is equal to the dimension of the second sidewall 220 along the first direction, and the position of the end of the first sidewall 210 along the first direction is offset from the position of the end of the second sidewall 220 along the first direction.

[0057] Please see Figure 5In some embodiments of this application, due to the inward-sloping upper end of the interface 300, the end of the first sidewall 210 facing the insertion end 302 of the interface 300 is not aligned with the end of the second sidewall 220 facing the insertion end 302 of the interface 300. In related technologies, for ease of manufacturing, when the outermost end of the first sidewall 210 is not aligned with the outermost end of the second sidewall 220, the innermost end of the first sidewall 210 is usually aligned with the innermost end of the second sidewall 220. In this case, the dimension of the first sidewall 210 along the first direction is smaller than the dimension of the second sidewall 220 along the first direction. In related technologies, the dimension of the second sidewall 220 along the first direction is usually increased to align their innermost ends. This can easily lead to a reduction in the metal volume in the reinforcing part 120, resulting in a decrease in the structural strength of the reinforcing part 120.

[0058] Please see Figure 6 In some embodiments of this application, the dimension of the first sidewall 210 along the first direction of the interface 300 and the dimension of the second sidewall 220 along the first direction of the interface 300 are both equal to L.

[0059] In this embodiment, by making the dimension of the first sidewall 210 along the first direction equal to the dimension of the second sidewall 220 along the first direction, and by offsetting the position of the end of the first sidewall 210 along the first direction from the position of the end of the second sidewall 220 along the first direction, the metal volume in the reinforcing part 120 can be retained to a greater extent, thereby improving the structural strength of the frame when the frame thickness is thin and the strength is weak.

[0060] Optionally, the reinforcing part 120 is aligned with one end of the insertion end 302 and the plastic part 200 is aligned with one end of the insertion end 302.

[0061] Compared to the conventional solution where the plastic at interface 300 extends completely beyond the edge of the metal frame 100, please refer to [link / reference needed]. Figure 6 In this embodiment of the application, the end of the plastic part 200 located at the insertion end 302 of the interface 300 is flush with the end of the reinforcing part 120 located at the insertion end 302 of the interface 300. In this way, the metal can play a certain protective role for the plastic part 200 during user use, and prevent the plastic part 200 from being damaged during use.

[0062] In this embodiment, by aligning the end of the reinforcing part 120 located at the insertion end 302 with the end of the plastic part 200 located at the insertion end 302, the reinforcing part 120 can provide a certain degree of protection for the plastic part 200, thus solving the problem that the plastic part 200 is easily damaged during use.

[0063] Optionally, the reinforcing part 120 has an arc-shaped chamfer 128 at one end of the insertion end 302.

[0064] exist Figure 5 In the illustrated embodiment, the inward reduction of the plastic part 200 is achieved by reducing the material of the metal frame 100 in the length direction. Therefore, Figure 5 The illustrated embodiment also increases the thickness dimension of the opening portion of interface 300. Figure 5 The value of H in the text. Compared to the conventional solution where the plastic completely extends beyond the edge of the metal frame 100, in the conventional solution, the thickness of the opening of the interface 300 is only the thickness of the plastic, while in this embodiment, the thickness of the opening of the interface 300 is the sum of the thickness of the plastic part 200 and the edge of the metal frame 100. Therefore, in this embodiment, the thickness of the opening of the interface 300 is larger, and the larger opening thickness allows for an R-angle to be formed on the metal. This R-angle is entirely on the metal and smoothly transitions with the curved surface of the metal, allowing for integral processing without any step difference issues. At the same time, the R-angle of the opening can also effectively improve the problem of scratching hands. The R-angle mentioned above is the aforementioned arc chamfer 128.

[0065] Please see Figure 5 To improve the problem of scratching hands, in this embodiment of the application, the R-angle of the opening of the interface 300 is extended from the middle position to both sides, so that the entire opening has no sharp corners, the transition is smooth, and the feel is further improved.

[0066] In this embodiment, by providing an arc-shaped chamfer 128 at one end of the reinforcing part 120 located at the insertion end 302, the problem of the edge of the electronic device being scratchy can be improved, which is beneficial to enhancing the user's experience of using the electronic device.

[0067] Optionally, the plastic part 200 is located between the position where the thickness of the reinforcing part 120 is the greatest and the insertion end 302.

[0068] Please see Figure 3 The reinforcing part 120 includes a first side 1221 and a second side 1222 facing away from each other. The first side 1221 is located on the side of the reinforcing part 120 that is away from the extension part 110, and the second side 1222 is located on the side of the reinforcing part 120 that faces the extension part 110. The connection between the first side 1221 and the second side 1222 is the position where the thickness of the metal frame 100 is the greatest.

[0069] The connection point between the first segment 1211 and the second segment 1212 is located on the side facing the first side 1221 at the position of maximum thickness.

[0070] Please see Figure 3 The first side 1221 and the second side 1222 mentioned above can be two opposite sides of the protruding portion of the reinforcing part 120 protruding from one side of the extension 110. Please refer to [link to relevant documentation]. Figure 3 From left to right, the thickness of the metal frame 100 gradually increases along the first side 1221 and gradually decreases along the second side 1222. Therefore, the connection between the first side 1221 and the second side 1222 is the position where the thickness of the metal frame 100 is the greatest.

[0071] The connection between the first segment 1211 and the second segment 1212 is located on the side facing the first side 1221 at the position of maximum thickness. That is, the depth of the first segment 1211 does not exceed the position of maximum thickness of the metal frame 100, meaning the plastic part 200 is located between the position of maximum thickness of the reinforcing part 120 and the insertion end 302. This avoids the problem of excessive metal reduction in the reinforcing part 120 due to excessive depth of the first segment 1211, which could lead to insufficient structural strength of the reinforcing part 120.

[0072] In this embodiment, by positioning the plastic part 200 between the position where the thickness of the reinforcing part 120 is greatest and the insertion end 302, the volume of the metal in the reinforcing part 120 can be largely preserved, ensuring that the reinforcing part 120 of the metal frame 100 has sufficient structural strength.

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.
