Description

Electronic equipment

The present application is a divisional application, the application number of the original application is 202011380630.8, the original application date is 2020, 11 months and 30 days, the name of the original application is "an electronic equipment framework", and the entire content of the original application is incorporated herein by reference.

Technical Field

The present application relates to the field of consumer electronics, and in particular, to an electronic device.

Background

The intelligent terminal product mainly adopts means such as dispensing or gum, forms the line of gluing between display screen and frame, realizes bonding and sealing of display screen and frame. In order to ensure that the glue line is continuously bonded without break points and liquid inlet risks, the air tightness of the glue line is required to be detected. The frame that glues the line gas tightness and detect and need bond the display screen cooperates with anchor clamps and forms airtight space, and original trompil is effectively sealed through anchor clamps on the frame. The frame is typically sealed against a Back Plate (BP) surface, i.e., a rear housing mounting surface, also known as a rear housing adhesive surface, in contact with the clamp. For metal frames, the BP face typically has both a metal face and a plastic face, and the junction of the plastic and metal, i.e., the heteroconjugate segment, has a height differential, commonly referred to as a step. The presence of the step makes it difficult for the clamp to form an effective seal with the frame. In order to ensure the effectiveness of the sealing of the frame and the clamp, the current common thinking is to eliminate the step difference, and the adopted means is to process the BP surface into a full numerical control machine (Computerized Numerical Control, CNC) surface or a full plastic rubber surface. However, the processing to the full CNC surface is to grind the step difference flat or small one by one, the working time is long, and the cost is high. The plastic thickness is required to be increased when the plastic surface is processed, so that the thickness of the whole machine is increased, the flexibility of material selection and structural design of the frame is limited, and the structural strength of the frame can be reduced if the thickness of the metal material is reduced.

Detailed Description

Referring first to fig. 1, a display screen 200 of an intelligent terminal product is generally adhered to a top surface of a body frame 100 by a glue line 300, and a rear case is adhered to a bottom surface of the body frame 100. The intelligent terminal product can be a mobile phone, a watch, a tablet and the like. The air tightness detection needs to be performed on the glue line 300, so that the glue line 300 is adhered continuously without break points. In the air tightness detection, as shown in fig. 2, the frame 100 with the display screen 200 adhered thereon is matched with the fixture 400 to form a closed space a, a certain air pressure (positive pressure or negative pressure) is applied to the closed space a through equipment, after the air pressure is stabilized to a certain value, the pressure is maintained for a period of time, for example, 5-10s, the air pressure change in the closed space a is detected, whether the glue line 300 leaks or not is determined, and the defect of the glue line 300 is identified.

The bottom surface of the frame 100 has a rear housing mounting surface 110, the rear housing mounting surface 110 being generally circumferentially distributed along the frame 100, the rear housing being connected to the frame 100 by the rear housing mounting surface 110. In the air tightness test, the rear case mounting surface 110 serves as a surface on which the frame 100 is in contact with the jig 400. The portion of the clamp 400 in contact with the frame 100, i.e., the seal ring, is made of a flexible material, and the clamp 400 is tightly attached to the frame 100 after being clamped. As shown in fig. 3, the rear housing mounting face 110 typically has both a plastic face 111 and a metal face 112. The junction of the two material faces, i.e., the heterojoined segment 120, has a height differential, commonly referred to as a step. In the air tightness detection, the existence of the step is easy to cause the leakage of the rear shell mounting surface 110, the sealing failure of the frame 100 and the clamp 400, the air pressure change in the closed space A is caused, and the air tightness detection is mistested.

The embodiment of the application provides an electronic device to improve the sealing effectiveness of a frame 100 and a clamp 400 when the air tightness of a glue line 300 is detected. The electronic device provided in the present application will be described in detail with reference to the accompanying drawings and specific embodiments.

The electronic device includes a frame 100 and a transition part 600, and a display screen 200 and a rear case, the display screen 200 and the rear case being disposed on top and bottom surfaces of the frame 100, respectively.

Referring to fig. 4, fig. 4 is a schematic diagram of a part of a structure of an electronic device according to an embodiment of the present application. As shown in fig. 4, the outer periphery of the bottom surface of the frame 100 has a continuous extension 500, and the extension 500 surrounds the rear case mounting surface 110. After the rear shell is installed, the rear shell is positioned within the extension part 500, and the extension part 500 can play a certain role in protecting the rear shell.

With continued reference to fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of a portion of the electronic device provided in the embodiment of the present application, and fig. 6 is a schematic structural diagram of a transition portion of the electronic device frame provided in the embodiment of the present application. As shown in fig. 5 and 6, the transition portion 600 is provided on the bottom surface of the frame 100. The transition 600 is located between the rear housing mounting surface 110 and the extension 500 and is connected to the rear housing mounting surface 110.

In one possible embodiment, the transition 600 is circumferentially adjacent to the heterojunction section 120 on the rear housing mounting surface 110, i.e., the surface junction of different materials on the rear housing mounting surface 110, of the frame 100. The transition portion 600 is plural, and both sides of the single hetero-joined section 120 in the circumferential direction of the frame 100 are provided with the transition portion 600, in other words, the single hetero-joined section 120 is sandwiched by the adjacent two transition portions 600.

In a specific implementation, the heteroconjugate section 120 with a large step, for example, the heteroconjugate section 120 at the side bond position of the frame 100, is especially provided with the transition part 600 on both sides, because the heteroconjugate section 120 with a large step has a large influence on the airtight detection of the glue line 300, and is easy to cause seal failure. The step size of the heterogeneous junction section 120 can be obtained through actual measurement, and the measurement means is mature and is not described too much.

With continued reference to fig. 7, fig. 7 is a schematic structural diagram of a transition portion of an electronic device frame according to an embodiment of the present disclosure. As shown in fig. 7, when the clip 400 is in contact engagement with the frame 100, the transition portion 600 presses the clip 400, changing the sealing path between the frame 100 and the clip 400, and transitioning the sealing path to a region having no or small step.

Referring to fig. 8 together, fig. 8 is a schematic diagram of a sealing path of the electronic device frame and the fixture according to the embodiment of the present application. As shown in fig. 8, two adjacent transition parts 600 sandwich the heterojunction segment 120, so that the sealing path does not pass through the heterojunction segment 120 any more, but passes through the extension part 500, the dashed line in the drawing indicates the sealing path, and the sealing path of the region of the heterojunction segment 120 becomes "the rear shell mounting surface 110-the transition part 600 on one side of the heterojunction segment 120-the extension part 500-the transition part 600 on the other side of the heterojunction segment 120-the rear shell mounting surface 110", thereby avoiding the influence of the step difference of the heterojunction segment 120 on the sealing effectiveness, forming a continuous sealing surface without break points, and avoiding the air tightness false measurement of the glue line 300. Further, the problem of misdetection of the air tightness of the glue line 300 caused by the roughness and microcrack of the rear housing mounting surface 110 can be solved. Note that, in fig. 8, only the sealing path of the area of the heterojunction section 120 is shown, that is, only a part of the sealing path is shown, and the remaining area without the heterojunction section 120 is still on the rear case mounting surface 110.

When the number of the heterojunction segments 120 is plural, the transition portion 600 is provided on both sides of each heterojunction segment 120 in the circumferential direction of the frame 100, particularly for the heterojunction segment 120 having a large step. Ensuring that the heterojunction segments 120 with the greater differences in the respective segments do not affect the effectiveness of the seal between the clamp and the frame 100.

When the two hetero-junction sections 120 are close, the transition portion 600 may not be disposed between the two hetero-junction sections 120, and the transition portion 600 is disposed on both sides of the whole of the two hetero-junction sections 120, so that the pair of transition portions 600 are shared. Of course, when adjacent transition portions 600 should be disposed at a relatively close distance, one transition portion 600 may be combined, for example, two heterogeneous coupling segments 120 share one transition portion 600 disposed therebetween, and three transition portions 600 are integrally used for two heterogeneous coupling segments 120 together with one transition portion 600 on each side.

The transition portion 600 changes the sealing path of the area where the heterojunction section 120 is located, and under the combined action of the plurality of transition portions 600, the frame 100 and the clamp 400 form a continuous effective seal along a circumference of the frame 100.

The contact surface of the sealing ring of the clamp 400 and the frame 100 adopts a profiling design, namely the contact surface is matched and arranged according to the positions and the shapes of the rear shell mounting surface 110 and the transition part 600, and the sealing position of the corresponding extension part 500 is designed into a plane, so that the clamp 400 and the frame 100 can be tightly attached, and the sealing effectiveness of the clamp 400 and the frame 100 is further ensured. The interference between the contact surface of the fixture 400 and the rear shell mounting surface 110, the transition portion 600 and the rest of the frame 100 is zero, the interference between the contact surface of the fixture 400 and the rest of the frame 100 is 0.1mm, and the interference between the contact surface of the fixture 400 and the extension portion 500 can represent the interference degree of the fixture 400 and the frame 100, so that the fixture 400 and the extension portion 500 can be tightly attached.

Regarding the extension shape of the transition portion 600, the transition portion 600 is linear when located on a straight side of the frame 100 and curved when located at a corner of the frame 100 along the circumferential direction of the frame 100. The length of the transition portion 600 may be greater than or equal to 0.8mm, and when the transition portion 600 is linear, the length is the distance from one end to the other end, and when the transition portion 600 is curved, the length is the distance from one end to the other end after being straightened. Illustratively, the transition 600 may be 0.8mm in length.

Regarding the position of the transition 600, the heterojunction section 120 on the rear housing mounting surface 110 is approached in the circumferential direction of the frame 100, on the basis of which the transition 600 may face the plastic surface 111 area of the rear housing mounting surface 110 in the vertical direction of the frame 100. For a single transition 600, the transition 600 is entirely within the extent of the plastic face 111 region extending vertically outward along the circumference of the frame 100.

In one possible embodiment, the transition 600 extends along the circumference of the frame 100, the transition 600 covering all of the heterojunction segments 120 on the rear housing mounting face 110 in the circumferential direction of the frame 100.

In particular implementations, the transition 600 may be a closed loop structure formed circumferentially around the frame 100, covering, of course, all of the heteroconjugate sections 120 circumferentially around the frame 100.

The transition portion 600 may also be an incomplete ring shape surrounding the circumference of the frame 100, that is, a ring shape surrounding the circumference of the frame 100 and having an opening, where the opening does not have the heterojunction section 120 on the rear housing mounting surface 110 corresponding to the vertical direction of the circumference of the frame 100.

It can be understood that: the first end of the transition part 600 starts from one side of a certain heterojunction section 120, and the second end surrounds along the circumferential direction of the frame 100, and may or may not be connected to the first end after the frame 100 circumferentially covers all the heterojunction sections 120 on the rear housing mounting surface 110. The transition portion 600 of the present embodiment covers all the heterojunction segments 120 without distinguishing the level difference of the heterojunction segments 120, and has a higher level of guarantee for sealing effectiveness.

With continued reference to fig. 9, fig. 9 is a schematic diagram of another sealing path for the electronic device frame and the fixture according to the embodiment of the present application. As shown in fig. 9, when the transition 600 is in a closed loop configuration, the sealing path is entirely over the transition 600, enabling a continuous, uninterrupted sealing surface between the frame 100 and the clamp 400.

Referring to fig. 10 together, fig. 10 is a schematic view of another sealing path of the electronic device frame and the fixture according to the embodiment of the present application. As shown in fig. 10, when the transition 600 is annular with an opening, the sealing path is "transition 600-extension 500 (at the opening of the corresponding transition 600) -transition 600", which enables a continuous non-break sealing surface between the frame 100 and the clip 400.

The surface of the transition part 600 extending from the rear housing mounting surface 110 to the extending part 500 is an arc surface, that is, the surface of the transition part 600 contacting the fixture 400 is an arc surface, and the radius value of the arc surface is greater than or equal to 0.4mm, so that the transition part 600 is tightly attached to the fixture 400, and the sealing reliability is higher. Summarizing from the machining process point of view, the R angle of the face of the transition 600 in contact with the jig 400 is 0.4 or more. Illustratively, the radius of the arcuate surface may be 0.4mm.

The material of the transition portion 600 may be plastic, and may be directly injection molded on the frame 100 to form a strip-shaped molding body. In a specific implementation, the transition portion 600 may be integrally injection molded with the plastic surface 111 of the rear housing mounting surface 110, so as to simplify the manufacturing process of the transition portion 600.

In addition to the setting manner of the electronic device in the above embodiment, the setting manner may be:

The transition 600 is provided at the bottom surface of the frame 100.

With continued reference to fig. 11, fig. 11 is a schematic structural diagram of a transition portion of an electronic device frame according to an embodiment of the present disclosure. As shown in fig. 11, a transition 600 is provided on the extension 500. The transition 600 extends in the circumferential direction of the extension 500, forming a closed loop structure. The transition 600 may entirely encase the extension 500 or may be disposed only on a side of the extension 500 that faces the bottom side of the frame 100.

With continued reference to fig. 12, fig. 12 is a schematic view of another sealing path of the electronic device frame and the fixture according to the embodiment of the present application. As shown in fig. 12, the transition 600 of the closed loop structure naturally covers all of the heterojunction segments 120 in the circumferential direction of the frame 100, and the sealing path is all over the extension 500, forming a continuous non-break sealing surface between the frame 100 and the clamp 400.

The transition portion 600 may be made of plastic, and may be directly injection molded on the extension portion 500 to form a ring-shaped plastic body with uniform material. Further, the transition portion 600 may be integrally injection molded with the plastic surface 111 of the rear housing mounting surface 110 to simplify the manufacturing process of the transition portion 600.

With continued reference to fig. 13, fig. 13 is a schematic diagram illustrating the cooperation between the electronic device frame and the fixture according to the embodiment of the present application. As shown in fig. 13, in the embodiment, the contact surface between the sealing ring of the clamp 400 and the frame 100, corresponding to the rear housing mounting surface 110 and the area between the rear housing mounting surface 110 and the extension 500, may have a gap B to ensure that the sealing ring of the clamp 400 is tightly attached to the transition portion 600.
