[0043] With the development of science and technology, smart handheld electronic devices such as mobile phones and tablets are ubiquitous in our lives. These devices mostly use touchscreens as their interaction medium for data collection and recognition. However, unlike stationary devices, handheld electronic devices are subject to the risk of accidental drops. When these devices fall to the ground, they often land on their corners, causing the corners of the device's casing to deform under pressure. This deformation can then crush the display screen, potentially causing it to shatter.

[0044] In view of this, embodiments of this application provide an electronic device that can reduce the risk of the display screen breaking when the electronic device is dropped.

[0045] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0046] like Figure 1 As shown in the embodiments of this application, an electronic device is disclosed. This electronic device can be a mobile phone, tablet computer, e-reader, wearable device, or other electronic product. This application does not impose any specific limitations on the type of electronic device. The electronic device includes:

[0047] The housing 100 is the outer shell of the electronic device, which may include a middle frame and a back cover. The display screen 200 mentioned below can be attached to one side of the middle frame by adhesive. The back cover can be attached to the side of the middle frame away from the display screen 200 by screwing, welding, bonding or fastening. This application embodiment does not impose special restrictions on the connection methods between the various components of the electronic device.

[0048] A display screen 200 is disposed within a housing 100. The inner peripheral wall of the housing 100 surrounds the outer edge of the display screen 200, meaning that at least a portion of the display screen 200 is located within the housing 100, and at least one corner of the display screen 200 has a clearance gap with the inner peripheral wall of the housing 100. For example, all portions of the display screen 200 may be located within the housing 100, meaning the display screen 200 does not have any portion protruding from the front side of the housing 100; or a portion of the display screen 200 may be located within the housing 100, and another portion may be located outside the housing 100, meaning the display screen 200 has a portion protruding from the front side of the housing 100.

[0049] In this application, at least one corner of the display screen 200 has a clearance gap between it and the inner peripheral wall of the housing 100. When the electronic device is dropped and the corner hits the ground, causing the housing 100 to deform, the clearance gap can provide clearance space for the deformation of the housing 100, achieving a buffering effect, thereby reducing the risk of the display screen breaking due to the housing 100 squeezing the display screen.

[0050] In one alternative embodiment, please refer to Figure 2The display screen 200 includes a cover plate 210 and a display module 220 stacked sequentially. In the electronic device, the cover plate 210 is closer to the user than the display module 220. In the direction from the display module 220 to the cover plate 210, the projection of the display module 220 on the cover plate 210 is located inside the cover plate 210. That is, the outer edge of the cover plate 210 protrudes from the outer edge of the display module 220 in a direction perpendicular to the arrangement direction of the display module 220 and the cover plate 210. At least one corner of the cover plate 210 has a clearance gap with the inner peripheral wall of the housing 100.

[0051] In this embodiment, the outer edge of the cover plate 210 protrudes beyond the outer edge of the display module 220. That is, the outer edge of the cover plate 210 is closer to the inner peripheral wall of the housing 100 than the outer edge of the display module 220. Thus, when the housing 100 deforms upon impact, the deformed housing 100 will only compress the cover plate 210 and not the display module 220. Even if the display screen 200 is damaged due to a drop, only the cover plate 210 will be damaged, not the display module 220. Clearly, the manufacturing cost of the cover plate 210 is much lower than that of the display module 220, which reduces the user's repair costs. Of course, the outer edge of the cover plate 210 can also be flush with the outer edge of the display module 220; this application does not limit this.

[0052] Specifically, the cover plate 210 is closer to the user than the display module 220. The cover plate 210 is transparent and allows light signals emitted from the display module 220 to pass through. The cover plate 210 also provides a touch interface for the user to interact with the display screen 200. For example, the material of the cover plate 210 can be glass or resin.

[0053] The display module 220 is equipped with a pixel array formed by multiple pixel units. Each pixel unit corresponds to a pixel circuit and a light-emitting unit. Driven by an external signal, each pixel unit in the pixel array can emit light signals of different colors to display images and videos.

[0054] In one optional embodiment, the width of the clearance gradually decreases in the direction extending from the corner of the cover plate 210 towards the center of its outer edge. For example, the maximum width of the clearance can be 0.1mm, 0.15mm, 0.2mm, etc.; taking a maximum clearance width of 0.15mm as an example, the width of the clearance can change from 0.15mm to 0.1mm, then to 0.05mm, and finally to 0mm.

[0055] Since the number of outer edges of the cover plate 210 includes multiple edges, each outer edge of the cover plate 210 will participate in the enclosure to form a corresponding corner. Therefore, each outer edge of the cover plate 210 will cooperate with the inner peripheral wall of the housing 100 to form a clearance gap. The "middle part of the outer edge of the cover plate 210" in the above "the width of the clearance gap gradually decreases in the direction extending from the corner of the cover plate 210 to the middle part of the outer edge of the cover plate 210" refers to the middle part of the outer edge of the cover plate 210 that cooperates with the inner peripheral wall of the housing 100 to form the clearance gap.

[0056] Taking the lower left corner of cover plate 210 as an example, please refer to... Figure 1 The lower left corner of the cover plate 210 is formed by the left edge and the lower edge of the cover plate 210. Both the left edge and the lower edge will cooperate with the inner peripheral wall of the housing 100 to form two different clearance gaps. The width of the clearance gap formed by the cooperation between the left edge and the inner peripheral wall of the housing 100 gradually decreases in the direction from the lower left corner to the middle of the left edge. The width of the clearance gap formed by the cooperation between the lower edge and the inner peripheral wall of the housing 100 gradually decreases in the direction from the lower left corner to the middle of the lower edge.

[0057] In this embodiment, the width of the clearance gradually decreases in the direction extending from the corner of the cover plate 210 towards the middle of its outer edge. That is, the gap between the middle of the outer edge of the cover plate 210 and the inner peripheral wall of the housing 100 is small, or even nonexistent. This improves the sealing performance between the cover plate 210 and the inner wall of the housing 100, preventing dust and other foreign matter from entering the housing 100. Of course, the width of the clearance can also remain constant in the direction extending from the corner of the cover plate 210 towards the middle of its outer edge; this application does not impose any limitation on this.

[0058] In other embodiments, the outer peripheral surface of the corner of the cover plate 210 may be curved to prevent stress concentration at the corner of the cover plate 210, which could lead to damage to the cover plate 210.

[0059] In one alternative embodiment, please refer to Figures 3 to 6 The electronic device also includes a flexible circuit board 300, an electrical connector 400, a compression piece 500, and screws (not shown) disposed within the housing 100. For example, the electronic device further includes a motherboard 600 for electrical connection with the display module 220. The electrical connector 400 is disposed on the motherboard 600. In this case, the end of the flexible circuit board 300 away from the motherboard 600 can be electrically connected to electronic modules such as a camera module. Signal interaction between the motherboard 600 and the camera module can be achieved through the flexible circuit board 300. The electrical connector 400 can be a board-to-board connector, etc.

[0060] The first end of the flexible circuit board 300 is electrically connected to the electrical connector 400. The first end is located between the extrusion plate 500 and the electrical connector 400. The extrusion plate 500 is connected to the housing 100 by screws so that the first end abuts against the electrical connector 400. Specifically, the flexible circuit board 300 is located on one side of the electrical connector 400. The surface of the flexible circuit board 300 facing the electrical connector 400 is provided with a first electrical connection terminal. The electrical connector 400 has a second electrical connection terminal facing the flexible circuit board 300. After the first electrical connection terminal and the second electrical connection terminal make electrical contact, the flexible circuit board 300 and the electrical connector 400 can be electrically connected.

[0061] In this embodiment, a pressing piece 500 is provided on the side of the flexible circuit board 300 away from the electrical connector 400, and the pressing piece 500 is fixed to the housing 100 by screws. The screws can apply a pressing force to the pressing piece 500, so that the pressing piece 500 applies a pressing force to the first end of the flexible circuit board 300, thereby causing the flexible circuit board 300 to abut against the electrical connector 400. Since the pressing piece 500 can apply a large pressing force to the flexible circuit board 300, it can prevent the flexible circuit board 300 from detaching from the electrical connector 400.

[0062] In one alternative embodiment, please refer to Figure 4 The extrusion sheet 500 includes an extrusion portion 510 and a fixing portion 520. A first end is located between the extrusion portion 510 and the electrical connector 400. Both ends of the extrusion portion 510 are connected to the fixing portion 520. The fixing portion 520 is positioned relative to the extrusion portion 510 along a first direction (…). Figure 4 The direction indicated by the arrow in the middle (x) is offset, that is, the fixing part 520 and the pressing part 510 are offset in the direction extending from one end of the pressing part 510 to the other end (i.e., ... Figure 4 The extrusion section 510 is offset along its length direction, with the first direction being the direction from the extrusion section 510 to the first end. The screw passes through the fixing part 520 and is connected to the housing 100, and the head of the screw abuts against the front of the extrusion section 510.

[0063] Generally, both the extrusion sheet 500 and the flexible circuit board 300 are disposed on the back side of the display screen 200. Therefore, in this embodiment, the fixing part 520 is offset relative to the extrusion part 510 along the first direction, so that the fixing part 520 is further away from the display screen 200 than the extrusion part 510, forming a receiving groove between the extrusion part 510 and the fixing part 520. After the screw head abuts against the front side of the extrusion part 510, at least a portion of the screw head will be accommodated in the receiving groove, thereby reducing the height of the fastener protruding from the front side of the extrusion part 510, thereby reducing the distance between the screw head and the display screen 200, and reducing the risk of damage to the display screen 200 due to contact between the screw head and the display screen 200. Of course, the front side of the extrusion part 510 and the front side of the fixing part 520 can also be flush, and this application does not limit this.

[0064] It should be noted that, in this application, the "front" of each component refers to the side of each component facing towards the user when the user is using the electronic device.

[0065] In some embodiments, the housing 100 is provided with a screw post 120, which is provided corresponding to the fixing part 520. One end of the screw passes through the fixing part 520 and is threadedly connected to the screw post 120. The screw post 120 can increase the engagement length between the screw and the housing 100, thereby improving the connection stability between the screw and the housing 100.

[0066] In one alternative embodiment, please refer to Figure 4 and Figure 6 The extrusion sheet 500 also includes a positioning part 530, which is connected to the end of the fixing part 520 opposite to the extrusion part 510. The positioning part 530 is provided with a positioning structure 531, which is positioned and engaged with the housing 100. For example, the positioning structure 531 can be a positioning hole, in which case the housing 100 is provided with a positioning post 110, which is positioned and engaged with the positioning hole. Of course, the positioning structure 531 can also be a positioning post 110, and this application does not limit this.

[0067] In this embodiment, the positioning part 530 of the extrusion piece 500 is provided with a positioning structure 531. When installing the extrusion piece 500, the positioning structure 531 can be positioned and engaged with the housing 100, so that the extrusion piece 500 is located in a preset installation position. In this way, the position of the extrusion piece 500 does not need to be adjusted multiple times, ensuring that the screw can pass through the preset position on the fixing part 520 and be threadedly connected to the preset position on the housing 100, thereby ensuring the connection strength between the screw and the housing 100. Of course, the extrusion piece 500 may not include the above-mentioned positioning part 530, and this application does not limit this.

[0068] In an optional embodiment, the electronic device further includes a buffer pad 700 located between the extrusion sheet 500 and the first end of the flexible circuit board 300. The buffer pad 700 can prevent the extrusion sheet 500 from scratching the flexible circuit board 300. Furthermore, the buffer pad 700 has a high coefficient of friction, which can generate greater friction between the buffer pad 700 and the extrusion sheet 500, and between the buffer pad 700 and the flexible circuit board 300, thereby preventing the flexible circuit board 300 from separating from the electrical connector 400.

[0069] In one alternative embodiment, please continue to refer to Figure 4 and Figure 6 The positioning portion 530 is offset relative to the fixing portion 520 in a first direction, that is, the front surface of the positioning portion 530 and the front surface of the fixing portion 520 are misaligned in the direction extending from one end of the compression portion 510 to the other. For example, the positioning portion 530 may be bent relative to the fixing portion 520.

[0070] In this embodiment, the housing 100 is provided with a positioning mating part, which is positioned and mated with the positioning structure 531. The positioning mating part is generally located at the bottom of the housing 100. The positioning part 530 is offset relative to the fixing part 520 along the first direction, so that the positioning part 530 is located closer to the bottom of the housing 100. Even if the positioning structure 531 on the positioning part 530 is closer to the positioning mating part, when one of the positioning structure 531 and the positioning mating part is a positioning hole and the other is a positioning post 110, the extension length of the positioning post 110 can be shortened to reduce the friction stroke between the positioning post 110 and the positioning hole during the mating process, so that the positioning post 110 can be smoothly inserted into the positioning hole, reducing assembly difficulty and assembly time. Of course, the front of the positioning part 530 and the front of the fixing part 520 can also be flush, and this application does not limit this.

[0071] In one alternative embodiment, please continue to refer to Figure 4 and Figure 6 The extrusion sheet 500 also includes a support portion 540. The support portion 540 is connected to the side of the fixing portion 520 adjacent to the extrusion portion 510. The support portion 540 is located on one side of the fixing portion 520 along the first direction and is in contact with the housing 100. For example, the support portion 540 can be formed by folding the edge of the fixing portion 520.

[0072] When the screw is connected to the housing 100, the screw head applies a compressive force in the first direction to the fixing part 520, causing a large internal stress within the fixing part 520. Therefore, in this embodiment, a support part 540 is connected to the fixing part 520. The support part 540 is in contact with the housing 100. When the screw head compresses the fixing part 520, the compressive force can be transmitted to the housing 100 along the support part 540. In other words, the support part 540 and the housing 100 can share the internal stress on the fixing part 520, thereby preventing damage to the fixing part 520. Of course, the compression plate 500 may not include the support part 540, and this application does not limit this.

[0073] In some embodiments, the support portion 540 has an arcuate structure, which gives the support portion 540 greater structural strength, thereby distributing greater internal stress and further preventing damage to the fixing portion 520.

[0074] In one alternative embodiment, please continue to refer to Figure 4 and Figure 6 The extrusion sheet 500 includes an extrusion portion 510 and a fixing portion 520. A first end is located between the extrusion portion 510 and the electrical connector 400. Both ends of the extrusion portion 510 are connected to the fixing portion 520. Screws pass through the fixing portion 520 and are connected to the housing 100. A reinforcing rib 511 is connected to the side of the extrusion portion 510 adjacent to the fixing portion 520. For example, the reinforcing rib 511 can be formed by folding the edge of the extrusion portion 510.

[0075] Since both ends of the extrusion part 510 are connected to the fixing part 520, when the screw is connected to the housing 100, the head of the screw will apply a first-direction extrusion force to the fixing part 520. Therefore, both fixing parts 520 on both sides will be subjected to the first-direction extrusion force. Under the action of the extrusion force on both sides, the extrusion part 510 has a tendency to arch and deform in the opposite direction of the first direction. If the extrusion force is too large, it will cause the extrusion part 510 to arch and deform in the opposite direction of the first direction. This will weaken the effect of the extrusion part 510 in extruding and fixing the flexible circuit board 300 and preventing the flexible circuit board 300 from detaching from the electrical connector 400.

[0076] Therefore, in this embodiment, a reinforcing rib 511 is connected to the side of the extrusion part 510 adjacent to the fixing part 520. The reinforcing rib 511 can improve the structural strength of the extrusion part 510. After the structural strength of the extrusion part 510 is improved, the ability of the extrusion part 510 to prevent deformation can be improved, so as to better resist the arching deformation of the extrusion part 510 in the opposite direction of the first direction, thereby ensuring the effect of the extrusion part 510 pressing and fixing the flexible circuit board 300 and preventing the flexible circuit board 300 from detaching from the electrical connector 400.

[0077] In a further embodiment, the reinforcing rib 511 is located on the side of the extrusion portion 510 facing the first end, so that the reinforcing rib 511 can be further away from the display screen 200, preventing the display screen 200 from coming into contact with the reinforcing rib 511 and damaging the display screen 200 during the use of the electronic device.

[0078] In one alternative embodiment, please refer to Figure 6 The first end is provided with a gap 310, which penetrates the two surfaces of the first end and extends along the length of the first end.

[0079] In this embodiment, the first end of the flexible circuit board 300 is provided with a through gap 310. The gap 310 extends along the length direction of the first end and can divide the first end of the flexible circuit board 300 into two sub-parts distributed along its own width direction. Each sub-part has a smaller width, and the smaller width can make each sub-part have a lower bending stiffness and be more prone to bending deformation. Thus, when the flexible circuit board 300 is subjected to external force, the aforementioned sub-parts are more likely to conform to the deformation caused by the external force, thereby releasing the external force and reducing the risk of the first end of the flexible circuit board 300 disengaging from the electrical connector 400, so as to ensure the normal operation of the electronic device.

[0080] In an alternative embodiment, the slit 310 extends to the end face of the first end, thereby further reducing the bending stiffness of the first end of the flexible circuit board 300, enabling it to adapt to deformation caused by external forces, and further reducing the risk of the first end of the flexible circuit board 300 becoming disconnected from the electrical connector 400.

[0081] In one alternative embodiment, the slit 310 is formed in the middle of the first board segment along its own width direction, and the extension direction of the slit 310 is perpendicular to the width direction of the first board segment. This makes the width of the portion of the flexible circuit board 300 located on both sides of the slit 310 equal, avoiding the appearance of a wider board segment and weakening the anti-detachment performance.

[0082] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. 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, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
