Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and in particular to electronic devices. Background Technology

[0002] Narrow bezel designs for electronic device screens increase the screen's display ratio by reducing the width of the physical bezels around the screen, which helps improve screen display quality and the thinness and lightness of electronic devices.

[0003] However, while narrowing the black bezel of the screen, it also brings the problem of a smaller gap between the screen structure and the mid-frame. This can cause the screen to collide with the mid-frame during drops, easily resulting in display problems such as black spots on the screen and affecting the user experience. Utility Model Content

[0030] Narrow bezels on electronic devices increase the screen-to-body ratio by reducing the width of the physical bezels around the screen, which helps improve display quality and the device's slimness. However, while narrowing the bezels, it also results in a smaller gap between the screen structure and the frame. This can cause screen damage such as black spots when the device is dropped, negatively impacting the user experience.

[0031] This disclosure provides an electronic device. Figure 1 This is a partial front view of an electronic device according to an exemplary embodiment of the present disclosure. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure at point AA is shown below. Figure 1 , Figure 2 As shown, Figure 2 The direction of the dashed arrow in the image represents the thickness direction. Electronic device 1 includes a screen module 11 and a mid-frame 12. The screen module 11 includes a cover layer 111 and functional components 112. The cover layer 111 and functional components 112 are stacked along the thickness direction of electronic device 1. The mid-frame 12 includes a sidewall structure 121 located around the screen module 11. In the thickness direction, the sidewall structure 121 includes a first portion 1211 aligned with the cover layer 111 and a second portion 1212 aligned with the functional components 112. The second inner surface 1212c of the second portion 1212 is recessed relative to the first inner surface 1211a of the first portion 1211 to form a clearance recess 1213.

[0032] The above solution divides the side wall structure 121 of the middle frame 12 into a first part 1211 aligned with the cover plate layer 111 of the screen module 11 and a second part 1212 aligned with the functional components 112 of the screen module 11 in the thickness direction. By the indentation of the second inner side surface 1212c of the second part 1212 relative to the first inner side surface 1211a of the first part 1211, the second inner side surface 1212c can avoid the functional components 112 after a collision. Moreover, the contact between the first inner side surface 1211a and the cover plate layer 111 can restrict the squeezing movement of the screen module 11 toward the middle frame 12, thus avoiding damage such as black spots on the screen caused by the collision.

[0033] It should be noted that the aforementioned sidewall structure 121 in the thickness direction includes a first portion 1211 aligned with the cover plate layer 111, meaning that the thickness section of the first portion 1211 of the sidewall structure 121 coincides with the thickness section of the cover plate layer 111. The aforementioned sidewall structure 121 in the thickness direction also includes a second portion 1212 aligned with the functional component 112, meaning that the thickness section of the second portion 1212 of the sidewall structure 121 coincides with the thickness section of the functional component 112.

[0034] When electronic device 1 collides, the collision between the side wall structure 121 of the mid-frame 12 and the screen module 11 mainly takes two forms: screen sliding collision and mid-frame 12 deformation and compression collision. Screen sliding collision failure usually occurs when the mid-frame 12 falls approximately perpendicularly to the ground. At the moment of impact, the screen module 11 slides obliquely outward. When this oblique outward sliding exceeds a certain amplitude, it will cause the functional components 112 of the screen module 11 to collide with the inner side wall of the mid-frame 12. Mid-frame 12 deformation and compression collision usually occurs when the entire electronic device 1 falls at a certain angle to the ground. The mid-frame 12 compresses inward and impacts the functional components 112 of the screen module 11, causing failure. To address the screen sliding collision failure issue, when the screen module 11 slides obliquely outward, the cover plate layer 111 preferentially collides with the first inner surface 1211a of the side wall structure 121, thereby preventing the screen module 11 from sliding further obliquely outward and avoiding collision between the side wall structure 121 of the mid-frame 12 and the functional components 112 of the screen module 11, reducing the risk of screen black spots from drops. Regarding deformation and compression collisions of the mid-frame 12, the recessed structure formed by the second inner surface 1212c relative to the first inner surface 1211a can provide sufficient clearance for the functional components 112 of the screen module 11, avoiding collision between the side wall structure 121 of the mid-frame 12 and the functional components 112 of the screen module 11, reducing the risk of screen black spots from drops.

[0035] In some embodiments, the first inner surface 1211a includes an impact mating plane extending along the thickness direction. The planar structure formed by the impact mating plane can form a reliable abutment relationship with the cover plate layer 111 when the electronic device 1 is impacted, thereby preventing the cover plate layer 111 from slipping during the abutment process with the first inner surface 1211a, improving the limiting stability of the screen module 11, and preventing the collision between the side wall structure 121 of the middle frame 12 and the functional components 112 of the screen module 11.

[0036] The cover plate layer 111 may include a first end face 1111 facing the first inner side surface 1211a. In the thickness direction, at least a portion of the impact mating plane is aligned with the first end face 1111. That is, the thickness section of part or all of the structure of the impact mating plane coincides with the thickness section of the first end face 1111. This positional relationship allows the impact mating plane to form abutment against the first end face 1111 during the impact process using the alignment structure, which helps to improve the positioning reliability of the screen module 11.

[0037] The aforementioned first inner surface 1211a may also include an arcuate surface or an inclined surface that is tilted relative to the thickness direction to match the structure of the first end face 1111 of the cover plate layer 111. The arcuate surface or the inclined surface can form a reliable contact limit with the cover plate layer 111 during the impact process. This disclosure does not limit the specific structure of the first inner surface 1211a.

[0038] In some embodiments, the second portion 1212 includes a first segment 1212a and a second segment 1212b. The first segment 1212a is connected to the first portion 1211, and the second segment 1212b extends from the first segment 1212a, with a width greater than that of the first segment 1212a. This structure enables the second segment 1212b to provide sufficient support strength for the entire sidewall structure 121, minimizing the deformation range and area of ​​the middle frame 12.

[0039] The aforementioned recessed relief 1213, which is recessed relative to the first inner surface 1211a, can be formed in the first segment 1212a, or in both the first segment 1212a and the second segment 1212b. When the relief 1213 is formed in the first segment 1212a, the width occupied by the second segment 1212b can be reduced, and the width of the second segment 1212b can provide sufficient support strength, minimizing the deformation range and area of ​​the middle frame 12. When the relief 1213 is formed in both the first segment 1212a and the second segment 1212b, the depth of the relief 1213 in the second segment 1212b can be less than the depth of the relief 1213 in the first segment 1212a, and the width of the second segment 1212b can also provide sufficient support strength, minimizing the deformation range and area of ​​the middle frame 12.

[0040] In the above embodiment, the first segment 1212a includes a first end connected to the first portion 1211, and the second segment 1212b includes a second end away from the first segment 1212a. The width of the second portion 1212 gradually increases from the first end to the second end. This gradual increase in width of the second portion 1212 from the first end to the second end ensures a smooth transition in the width of the second portion 1212 of the sidewall structure 121, preventing the structure at the abrupt width change from colliding with the functional components 112 of the screen module 11 during a collision. For example, the gradual increase can be linear or exponential, and this disclosure does not limit this.

[0041] In other embodiments, the width of the first segment 1212a and the width of the second segment 1212b may also change in a stepped manner.

[0042] In some implementations, the second segment 1212b may also include a middle sub-segment and a bottom sub-segment. The width of the middle sub-segment may be greater than the width of the first segment 1212a and less than the width of the bottom sub-segment. The width variations of the first segment 1212a, the middle sub-segment, and the bottom sub-segment may be linear, exponential, or stepped. These variations can be set according to specific needs and requirements of the functional component 112. In the event of the aforementioned sliding collision and deformation and compression collision of the middle frame 12 during a drop, the impact of the collision on the screen functional component 112 can be effectively mitigated, thereby reducing the risk of black spots on the screen display.

[0043] In some embodiments, the second inner surface 1212c may include an arc-shaped structure, which can be used for a smooth transition of the structure and can also be used to match the structure of the second inner surface 1212c with the end face structure of the functional component 112, thereby improving the avoidance effect in impact scenarios.

[0044] In some embodiments, the arc-shaped structure is connected to the first inner surface 1211a. The connection between the arc-shaped structure and the first inner surface 1211a can form a smooth transition between the first inner surface 1211a and the second inner surface 1212c. The arc-shaped structure can also be used to achieve the bending of the second inner surface 1212c relative to the first inner surface 1211a and to avoid the formation of the recess 1213, thereby improving the smoothness of the structure.

[0045] In some embodiments, the functional component 112 includes an encapsulation structure 1121 and a display component 1122. The display component 1122 includes a second end face 1122a facing the sidewall structure 121 and a first bottom face 1122b facing away from the cover plate layer 111. The encapsulation structure 1121 covers the second end face 1122a and the first bottom face 1122b. By encapsulating the second end face 1122a and the first bottom face 1122b of the display component 1122 with the encapsulation structure 1121, protection is formed for the display component 1122, preventing damage caused by direct contact between the middle frame 12 and the display component 1122 when the electronic device 1 is impacted.

[0046] The encapsulation structure 1121 may include the traces of the screen module 11 and the protective structure covering the traces. The encapsulation structure 1121 itself forms protection for the traces and can also cover part of the structure of the display component 1122 to form protection for the display component 1122.

[0047] In the above embodiment, the encapsulation structure 1121 includes a third end face 1121a disposed toward the second inner side face 1212c. Within at least one thickness segment, the distance between the second inner side face 1212c and the third end face 1121a is the same at any thickness position, so that the distance from the third end face 1121a to the second inner side face 1212c is the same in the thickness segment, thus avoiding damage caused first by the closer distance between the third end face 1121a and the second inner side face 1212c after impact.

[0048] In some embodiments, the mid-frame 12 further includes a mid-plate 122, which is connected to the end of the second portion 1212. The functional component 112 includes a second bottom surface 113 facing away from the cover plate layer 111. The mid-plate 122 is bonded to the second bottom surface 113 with adhesive. The connection between the mid-plate 122 and the end of the second portion 1212 can strengthen the structural strength of the sidewall portion and reduce excessive deformation of the mid-frame 12 after impact. The bonding and fixation of the second bottom surface 113 of the functional component 112 and the mid-plate 122 can also improve the overall structural strength of the assembly of the mid-frame 12 and the screen module 11.

[0049] This disclosure is based on tests of two models. The first model is a model that does not include the structural features of the electronic device 1 disclosed herein, and the second model is a model that includes the technical features of this disclosure. Taking the first model with a total weight of 192g and the second model with a total weight of 217g, the first model with a total size of 152.3mm x 71.2mm and the second model with a total size of 162.9mm x 77.58mm as an example, under the same test conditions, the failure rate of the first model is 22 / 30, and the failure rate of the second model is improved to 5 / 30.

[0050] The aforementioned electronic device 1 can be a mobile terminal such as a mobile phone, tablet computer, vehicle terminal, medical terminal, or wearable device, or it can be a vehicle, mobile cleaning equipment, robot, etc. This disclosure does not limit it in this regard.
