Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of electronic devices, and in particular, to an electronic device. BACKGROUND

[0002] In an electronic device, an edge of a display panel is often provided with a bending part for electrical signal transmission, and low-temperature injection molding is often performed outside the bending part to form a protective piece for protecting the edge of the display panel.

[0003] In related technologies, when the display panel is mounted, two back adhesives are attached to the middle frame to respectively realize the connection between the protective piece, the non-bending part of the display panel and the middle frame. The end portions of the two back adhesives often have a gap. In order to ensure the sealing effect of the electronic device, glue needs to be injected into the gap to block the gap.

[0004] However, in the above structure, since the end portions of the two back adhesives are located close to the frame, when the display panel is connected to the middle frame, the display panel will squeeze the glue in the gap, which may cause the glue to overflow to the appearance surface of the electronic device, thereby increasing the cleaning cost of the electronic device. UTILITY MODEL CONTENT

[0005] The embodiments of the present disclosure provide an electronic device, which can solve the above technical problems in related technologies. The technical solution is as follows:

[0006] An electronic device, the electronic device comprising a middle frame, a display panel, a protective piece and a connecting assembly. The display panel is stacked with the middle frame, the display panel comprising a bending part and a non-bending part connected with each other, the bending part being located at the edge of the non-bending part and being bent towards the side close to the middle frame. The protective piece comprising a first connecting part, a protection part and a second connecting part connected with each other in sequence, the first connecting part and the second connecting part being respectively located at the side of the non-bending part close to the middle frame and at the opposite two edges of the non-bending part, and the protection part wrapping the bending part. The connecting assembly comprising a first glue layer, a second glue layer and a blocking glue body, the first glue layer connecting the middle frame and the protective piece, the second glue layer connecting the middle frame and the non-bending part, a part of the second glue layer being adjacent to the first glue layer and having a gap in the width direction of the middle frame, and the blocking glue body being located in the gap and connected with the first glue layer and the second glue layer.

[0007] In this way, by arranging the blocking glue body in the gap between the first glue layer and the second glue layer in the width direction of the middle frame, when the display panel is connected to the middle frame, the glue can flow along the gap due to the blocking of the first glue layer, the second glue layer and the protective piece when being squeezed, and it is difficult to flow to the frame, thereby reducing the possibility of glue overflowing to the appearance surface of the electronic device, and thereby saving the cleaning cost of the electronic device.

[0008] In some possible implementation manners, the sealing glue body is in a strip shape and extends along the extension direction of the interval.

[0009] In this way, the middle part of the sealing glue body can fill the partial space between the display assembly and the middle frame, so that the sealing performance of the sealing glue body can be ensured.

[0010] In some possible implementation manners, the connecting assembly includes a plurality of sealing glue bodies, and the plurality of sealing glue bodies are arranged in the interval in a spaced manner.

[0011] In this way, the situation that the electronic device is sealed between the first glue layer and the second glue layer due to the failure of the individual sealing glue body can be avoided, so that the sealing performance of the sealing glue body can be ensured.

[0012] In some possible implementation manners, the middle frame has a receiving groove, and the receiving groove is used to accommodate the first glue layer.

[0013] In this way, the first glue layer can be lower than the second glue layer, so that the thickness of the second glue layer can be reduced, and the overall electronic device can be made thinner.

[0014] In some possible implementation manners, the receiving groove is also used to accommodate a part of the protection member.

[0015] In this way, the protection member can be positioned by the receiving groove during the connection of the display panel and the middle frame, so that the convenience of the connection of the display panel and the middle frame can be improved.

[0016] In some possible implementation manners, the interval has a size of 0.2 mm to 0.7 mm in the width direction of the middle frame.

[0017] In this way, the possibility that the sealing glue body is knocked off can be reduced, and the sealing effect of the sealing glue body can be improved.

[0018] In some possible implementation manners, the middle frame includes a middle plate and a frame, the middle plate is fixed in the frame, the display panel is laminated with the middle plate, the first glue layer and the second glue layer are respectively fixed to the middle plate, and the part of the second glue layer adjacent to the first glue layer in the width direction of the middle frame is located on the side of the first glue layer away from the frame.

[0019] In this way, the complexity of the injection molding process of the protection member can be reduced, and the production cost of the electronic device can be reduced.

[0020] In some possible implementation manners, the middle frame includes a middle plate and a frame, the middle plate is fixed in the frame, and the display panel is laminated with the middle plate. The first glue layer and the second glue layer are both spaced from the frame.

[0021] Therefore, when the electronic device is impacted, the frame can avoid directly impacting the first adhesive layer or the second adhesive layer, so that the possibility of the first adhesive layer or the second adhesive layer being loosened by impact can be reduced, and the electronic device can have good sealing performance.

[0022] In some possible implementation manners, the middle frame includes a middle plate and a frame, the middle plate is fixed in the frame, the display panel is laminated with the middle plate, and a safety gap exists between the protection member and the frame.

[0023] Therefore, when the electronic device is impacted, the frame can avoid directly impacting the protection member, so that the possibility of the protection member being damaged by impact can be reduced, and the service life of the display surface can be improved.

[0024] In some possible implementation manners, the safety gap has a width of 0.01 mm to 0.15 mm.

[0025] Therefore, the black border size of the display panel can be small under the premise of ensuring the anti-impact effect of the safety gap, and the user experience can be improved.

[0026] It should be understood that the general description above and the detailed description below are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0037] To make the objects, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.

[0038] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0039] The present disclosure provides an electronic device. The electronic device can also be referred to as a terminal, a mobile terminal, a terminal device, a user equipment (UE), etc. Exemplarily, the terminal device can be a smart phone, a tablet computer, etc. It should be understood that the present disclosure does not specifically limit the specific technology and specific device form of the terminal device. In the following description of the embodiments, a mobile phone is taken as an example for description, but the present disclosure is not limited thereto.

[0040] As shown in Figure 1 , the electronic device includes a middle frame 1, a display panel 2, a protection piece 3 and a connecting assembly 4. The display panel 2 is laminated with the middle frame 1, and the display panel 2 includes a bending part 21 and a non-bending part 22 connected with each other, the bending part 21 is located at the edge of the non-bending part 22 and is bent towards the side close to the middle frame 1. Figure 4 As shown in Figure 2 , the protection piece 3 includes a first connecting part 31, a protection part 32 and a second connecting part 33 connected in sequence, the first connecting part 31 and the second connecting part 33 are respectively located at the side of the non-bending part 22 close to the middle frame 1 and are respectively located at the opposite two edges of the non-bending part 22, and the protection part 32 wraps the bending part 21. Figure 2 As shown in Figure 2 , the connecting assembly 4 includes a first adhesive layer 41, a second adhesive layer 42 and a sealing adhesive 43, the first adhesive layer 41 connects the middle frame 1 and the protection piece 3, the second adhesive layer 42 connects the middle frame 1 and the non-bending part 22, part of the second adhesive layer 42 is adjacent to the first adhesive layer 41 in the width direction of the middle frame 1 and there is a gap, the sealing adhesive 43 is located in the gap and is connected with the first adhesive layer 41 and the second adhesive layer 42.

[0041] In the embodiments of the present disclosure, by arranging the blocking glue body 43 in the interval between the first glue layer 41 and the second glue layer 42 in the width direction of the middle frame 1, when the display panel 2 is connected to the middle frame 1, the glue can flow along the interval due to the blocking of the first glue layer 41, the second glue layer 42 and the protective piece 3 when the glue is extruded, and it is difficult to flow to the frame 12, thereby reducing the possibility of glue overflowing to the appearance surface of the electronic device, and further saving the cleaning cost of the electronic device.

[0042] The protective piece 3 is formed by a low-temperature injection molding process, which is mainly used for structural reinforcement of the bending part 21 to protect it. The bending part 21 has a multi-layer structure, and the protective piece 3 can be partially filled between the multi-layer structure to further improve the protection effect of the bending part 21.

[0043] Optionally, the first glue layer 41 and the second glue layer 42 can be foam glue. The foam glue has elasticity, so that the foam glue can absorb external impact or vibration, thereby reducing the risk of cracking or internal component damage of the display panel 2 due to bumping or extrusion. In addition, the foam glue has good waterproof performance, thereby improving the sealing performance of the electronic device.

[0044] Optionally, the blocking glue body 43 can be formed by dispensing. For example, liquid glue can be placed in the interval between the first glue layer 41 and the second glue layer 42 in the width direction of the middle frame 1, and the liquid glue is accumulated to a certain height. When the display panel 2 is connected to the middle frame 1, the protective piece 3 is fixedly connected with the first glue layer 41, and the non-bending part 22 of the display panel 2 is fixedly connected with the second glue layer 42, so that the display panel 2 extrudes the glue in the interval to realize the sealing between the first glue layer 41 and the second glue layer 42 of the electronic device.

[0045] As shown in FIG. 1, Figure 1 The middle frame 1 includes a middle plate 11 and a frame 12, and the middle plate 11 is fixed in the frame 12. The display panel 2 is stacked with the middle plate 11, and the first glue layer 41 and the second glue layer 42 are fixed to the middle plate 11. Therefore, the display panel 2 can be connected and fixed by the middle plate 11, and the display panel 2 can be protected by the frame 12.

[0046] In combination with Figure 2 , Figure 3 , Figure 4As shown, the protective component 3 is U-shaped, and correspondingly, the first adhesive layer 41 is also U-shaped. The connecting assembly 4 includes at least two sealing adhesives 43, which are located on the sides of the first connecting portion 31 and the second connecting portion 32, respectively. This allows for sealing of the first adhesive layer 41 and the second adhesive layer 42 on both sides of the U-shaped protective component 3, ensuring good sealing performance of the electronic device at that location. Of course, the protective component 3 can also be of other shapes. In some other examples, the protective component 3 further includes a first extension and a second extension. The first extension extends from the first connecting portion 31 to the first side of the earpiece of the electronic device, and the second extension extends from the second connecting portion 32 to the first side of the earpiece of the electronic device. The earpiece of the electronic device is located on one side of the bent portion 21 of the middle plate 11. This disclosure does not limit the scope of the embodiments.

[0047] In some examples, the sealing colloid 43 is in the form of strips and extends along the direction of the spacing.

[0048] Thus, due to the fluidity of the liquid adhesive, even if the edge of the sealing adhesive 43 in the length direction may not completely fill the space between the display component and the middle frame 1 in the thickness direction, the sealing adhesive 43 has a large size in the extension direction of the interval, which allows the middle part of the sealing adhesive 43 to fill the space between the display component and the middle frame 1, thereby ensuring that the sealing adhesive 43 has good sealing performance.

[0049] In some examples, the connecting component 4 includes a plurality of sealing adhesives 43, which are spaced apart within a space.

[0050] Thus, by setting multiple sealing colloids 43 within the interval, it is possible to avoid the situation where the sealing of the electronic device between the first adhesive layer 41 and the second adhesive layer 42 fails due to the failure of individual sealing colloids 43, thereby ensuring that the sealing colloids 43 have good sealing performance.

[0051] In some examples, combined Figure 2 , Figure 3 As shown, the middle frame 1 has a receiving groove 1a for receiving the first adhesive layer 41.

[0052] Because of the presence of the protective component 3, when connecting the display panel 2, the protective component 3 protrudes from the back of the display panel 2. If the display panel 2 does not have a receiving groove 1a, the thickness of the first adhesive layer 41 needs to be equal to the sum of the thickness of the second adhesive layer 42 and the portion of the protective component 3 protruding from the back of the display panel 2, which would result in a relatively large thickness of the first adhesive layer 41. By providing the receiving groove 1a to accommodate the first adhesive layer 41, the first adhesive layer 41 can be made lower than the second adhesive layer 42, thereby reducing the thickness of the second adhesive layer 42 and making the overall electronic device thinner and lighter.

[0053] In some examples, as shown in Figure 2 The accommodating groove 1a is also used to accommodate a part of the protective piece 3.

[0054] By accommodating a part of the protective piece 3 through the accommodating groove 1a, the thickness of the first glue layer 41 can be further reduced, so that the whole electronic device is more lightweight. In addition, during the connection process of the display panel 2 and the middle frame 1, the protective piece 3 can also be positioned through the accommodating groove 1a, so as to improve the convenience of connecting the display panel 2 and the middle frame 1.

[0055] In some examples, the size of the interval in the width direction of the middle frame 1 is 0.2mm-0.7mm.

[0056] The size of the interval in the width direction of the middle frame 1 is 0.2mm-0.7mm means that the size of the interval in the width direction of the middle frame 1 is greater than or equal to 0.2mm and less than or equal to 0.7mm. The subsequent related description is also determined in this way, and will not be repeated here.

[0057] If the size of the interval in the width direction of the middle frame 1 is less than 0.2mm, the blocking glue 43 may be impacted and fall off when the electronic device is impacted, thereby causing blocking failure. If the size of the interval in the width direction of the middle frame 1 is greater than 0.7mm, after the glue is put into the interval, due to the fluidity of the glue, there is a gap between the glue and the back of the display panel 2, thereby making it difficult to guarantee the blocking effect of the formed blocking glue 43. Therefore, by setting the size of the interval in the width direction of the middle frame 1 to 0.2mm-0.7mm, the possibility of the blocking glue 43 being impacted and falling off can be reduced, and the blocking effect of the blocking glue 43 can be improved.

[0058] Alternatively, the size of the interval in the width direction of the middle frame 1 can be, for example but not limited to, 0.3mm, 0.4mm, 0.5mm or 0.6mm.

[0059] In some examples, as shown in Figure 3 The part of the second glue layer 42 adjacent to the first glue layer 41 in the width direction of the middle frame 1 is located on the side of the first glue layer 41 away from the frame 12.

[0060] If the part of the second adhesive layer 42 adjacent to the first adhesive layer 41 in the width direction of the middle frame 1 is arranged on the side of the first adhesive layer 41 close to the bezel 12, a certain interval needs to exist between the first connecting part 31, the second connecting part 32 and the edge of the display assembly in the injection molding process, which increases the complexity of the injection molding process and the overall production cost. The second adhesive layer 42 is a back adhesive, and its shape is convenient to adjust. If the part of the second adhesive layer 42 adjacent to the first adhesive layer 41 in the width direction of the middle frame 1 is arranged on the side of the first adhesive layer 41 away from the bezel 12, the first connecting part 31 and the second connecting part 32 can be arranged at the edge of the display assembly, thereby reducing the complexity of the injection molding process of the protection piece 3 and the production cost of the electronic device.

[0061] In some examples, the first adhesive layer 41 and the second adhesive layer 42 both have a gap with the bezel 12.

[0062] In this way, when the electronic device is impacted, the bezel 12 can avoid directly impacting the first adhesive layer 41 or the second adhesive layer 42, thereby reducing the possibility of the first adhesive layer 41 or the second adhesive layer 42 being loosened by impact, and further ensuring that the electronic device has good sealing performance.

[0063] Optionally, the gap between the part of the first adhesive layer 41 adjacent to the bezel 12 and not adjacent to the second adhesive layer 42 and the bezel 12 is 0.2mm-0.7mm, and the gap between the part of the second adhesive layer 42 adjacent to the bezel 12 and not adjacent to the first adhesive layer 41 and the bezel 12 is 0.2mm-0.7mm. If the above two gaps are less than 0.2mm, the anti-impact performance of the electronic device is difficult to guarantee; if the above two gaps are greater than 0.7mm, the adhesive layer is far away from the bezel 12, which may occupy the space of other components, which is not conducive to the internal space layout of the electronic device. Therefore, the above two gaps are 0.2mm-0.7mm, which can balance the anti-impact performance of the electronic device and the optimization of the internal space of the electronic device.

[0064] In some examples, a safety gap exists between the protection piece 3 and the bezel 12.

[0065] In this way, when the electronic device is impacted, the bezel 12 can avoid directly impacting the protection piece 3, thereby reducing the possibility of the protection piece 3 being damaged by impact, and further improving the service life of the display surface.

[0066] In some examples, the width of the safety gap is 0.01mm-0.15mm.

[0067] If the width of the safety gap is less than 0.01 mm, the anti-impact effect of the safety gap is difficult to guarantee when the electronic device is impacted. If the width of the safety gap is greater than 0.15 mm, the width of the safety gap is too large, thereby causing a large black border of the display assembly. Thus, the width of the safety gap is set to 0.01 mm-0.15 mm, which can make the black border size of the display panel 2 smaller on the premise of guaranteeing the anti-impact effect of the safety gap, thereby being capable of improving the user experience.

[0068] Optionally, the width of the safety gap can be, for example but not limited to, 0.05 mm, 0.10 mm or 0.13 mm.
