[0053] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0054] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0055] The display device housing and the display device of the embodiment of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can complement or be combined with each other.

[0056] The present application embodiment provides a display device housing, such as Figures 1 to 4 As shown, the display device housing includes a rear housing 10 and a middle frame 20; the rear housing 10 includes a bottom plate 11 and a plurality of first buckles 12. The middle frame 20 includes a main body 21 and a plurality of second buckles 22 connected to the main body 21. Figure 5 and Figure 6 As shown, each of the first buckles 12 includes a first extension portion 121 and a first limiting portion 122. One end of the first extension portion 121 is connected to the bottom plate 11, and the other end is connected to the first limiting portion 122.

[0057] like Figure 5 and Figure 6As shown, the main body 21 is provided with an accommodating space 30 for accommodating a display module. Each second buckle 22 includes a second extension portion 221 formed by the main body 21 extending toward the bottom plate 11 and a second stop portion 222 connected to the end of the second extension portion 221 facing the bottom plate 11. The first stop portion 122 is located on the side of the bottom plate 11 facing the middle frame 20, and each first stop portion 122 cooperates with one second stop portion 222 to connect the rear housing 10 to the middle frame 20.

[0058] When assembling the rear shell 10 and the middle frame 20, the first buckle 12 is directed toward the second buckle 22, and each first buckle 12 is aligned with a second buckle 22, and then the rear shell 10 is moved toward the middle frame 20 as a whole, so that the first limiting portion 122 and the second limiting portion 222 can be matched, and the assembly of the rear shell 10 and the middle frame 20 is completed.

[0059] The first extension portion 121 and the second extension portion 221 both have a certain length and can produce a certain elastic deformation when subjected to external force. This elastic deformation can not only provide sufficient clamping force during installation to ensure the close fit between the first limiting portion 122 and the second limiting portion 222, but also reduce the rigid stress on the first limiting portion 122 and the second limiting portion 222 during the separation process, thereby avoiding the first clip 12 and the second clip 22 from breaking due to excessive rigidity during the separation process, making it easier to disassemble the rear shell 10 and the middle frame 20.

[0060] In one embodiment, Figure 6 As shown, the surface of the first limiting portion 122 facing the bottom plate 11 is a first abutting surface 1221, and the surface of the second limiting portion 222 facing the main body 21 is a second abutting surface 2221. When the first limiting portion 122 cooperates with the second limiting portion 222, the first abutting surface 1221 abuts against the second abutting surface 2221. After the rear shell 10 and the middle frame 20 are assembled, the first abutting surface 1221 can limit the second buckle 22 from moving away from the bottom plate 11, and the second abutting surface 2221 can limit the first buckle 12 from moving away from the main body 21, thereby ensuring a tight connection between the rear shell 10 and the middle frame 20, and preventing the rear shell 10 and the middle frame 20 from loosening or detaching due to external impact or vibration.

[0061] In one embodiment, Figure 6 As shown, the first limiting portion 122 is provided with a first guiding surface 1222 located on the side of the first abutting surface 1221 away from the bottom plate 11, and the first guiding surface 1222 is an inclined surface or an arc surface intersecting with the extending direction of the first extending portion 121. Figure 6As shown, the first guide surface 1222 is an inclined surface, and from the edge of the first guide surface 1222 away from the corresponding second extension portion 221 to the edge close to the corresponding second extension portion 221, the first guide surface 1222 is inclined toward the direction close to the bottom plate 11. The first guide surface 1222 can guide the second position-limiting portion 222 to move relative to the first position-limiting portion 122, reduce the resistance encountered by the first position-limiting portion 122 in the process of moving relative to the second position-limiting portion 222, make the assembly process of the first position-limiting portion 122 and the second position-limiting portion 222 smoother, help reduce the difficulty of alignment when assembling the two, and avoid damage to the first buckle 12 or the second buckle 22 due to excessive force.

[0062] In one embodiment, Figure 6 As shown, the second limiting portion 222 is provided with a second guiding surface 2222 located on the side of the second abutting surface 2221 away from the main body 21. The second guiding surface 2222 is an inclined surface or an arc surface intersecting with the extension direction of the second extension portion 221. Figure 6 As shown, the second guide surface 2222 is an inclined surface, and from the edge of the second guide surface 2222 away from the corresponding first extension portion 121 to the edge close to the corresponding first extension portion 121, the second guide surface 2222 is inclined in the direction close to the main body 21. The second guide surface 2222 can guide the first limiting portion 122 to move relative to the second limiting portion 222, reduce the resistance encountered by the second limiting portion 222 in the process of moving relative to the first limiting portion 122, make the assembly process of the first limiting portion 122 and the second limiting portion 222 smoother, help reduce the difficulty of alignment when assembling the two, and avoid damage to the first buckle 12 or the second buckle 22 due to excessive force.

[0063] Specifically, when the first buckle 12 and the second buckle 22 are docked, the first guide surface 1222 and the second guide surface 2222 first contact each other. Under the action of external force, the first guide surface 1222 and the second guide surface 2222 slide relative to each other, guiding the first buckle 12 to move toward the main body 21 and the second buckle 22 to move toward the bottom plate 11, and finally making the first abutting surface 1221 abut against the second abutting surface 2221. In the process of relative movement of the first buckle 12 and the second buckle 22, the first extension portion 121 and the second extension portion 221 undergo elastic deformation, which can reduce the force required for the assembly of the first limiting portion 122 and the second limiting portion 222, and reduce the difficulty of assembly. After the first abutting surface 1221 and the second abutting surface 2221 abut against each other, the first extension portion 121 and the second extension portion 221 recover their deformation, ensuring the stability of the first buckle 12 and the second buckle 22 after the clamping.

[0064] In one embodiment, Figure 7As shown, both the first abutting surface 1221 and the second abutting surface 2221 are inclined surfaces, the first abutting surface 1221 intersects with the extension direction of the first extension portion 121, and the second abutting surface 2221 intersects with the extension direction of the second extension portion 221. From the edge where the first abutting surface 1221 is connected to the first extension portion 121 to the edge away from the first extension portion 121, the first abutting surface 1221 is inclined in a direction away from the bottom plate 11. From the edge where the second abutting surface 2221 is connected to the second extension portion 221 to the edge away from the second extension portion 221, the second abutting surface 2221 is inclined in a direction away from the main body portion 21.

[0065] When the rear shell 10 and the middle frame 20 are disassembled, under the action of external force, the first buckle 12 moves in a direction away from the main body 21, and the second buckle 22 moves in a direction away from the bottom plate 11. During the movement, the first limiting portion 122 moves along the second abutting surface 2221 in a direction away from the second extension portion 221, and the second limiting portion 222 moves along the first abutting surface 1221 in a direction away from the first extension portion 121, until the first abutting surface 1221 and the second abutting surface 2221 are not in contact with each other, the first limiting portion 122 and the second limiting portion 222 are separated, and the rear shell 10 and the middle frame 20 can be disassembled. The inclined design of the first abutting surface 1221 and the second abutting surface 2221 can reduce the resistance of the first limiting portion 122 and the second limiting portion 222 during the relative movement when the rear shell 10 and the middle frame 20 are disassembled, so that the first buckle 12 and the second buckle 22 are easier to separate, and the buckle damage caused by excessive force is avoided.

[0066] In one embodiment, Figure 6 As shown, the first buckle 12 further includes a first reinforcement portion 123, which is located at the side of the first extension portion 121 and is respectively connected to the end of the first extension portion 121 close to the bottom plate 11 and the bottom plate 11. The first reinforcement portion 123 improves the structural strength of the connection between the first buckle 12 and the bottom plate 11, and reduces the risk of the first buckle 12 breaking during the installation and removal of the rear shell 10 and the middle frame 20.

[0067] In one embodiment, Figure 6 As shown, the second buckle 22 further includes a second reinforcing portion 223, which is located at the side of the second extension portion 221 and is connected to the end of the second extension portion 221 close to the main body and to the main body, respectively. The second reinforcing portion 223 improves the structural strength of the connection between the second buckle 22 and the main body 21, and reduces the risk of the second buckle 22 breaking during the installation and removal of the rear shell 10 and the middle frame 20.

[0068] In one embodiment, Figure 5 and Figure 6 As shown, the cross-sectional area of ​​the first reinforcing portion 123 gradually decreases from the end of the first buckle 12 connected to the bottom plate 11 to the direction of the first limiting portion 122. The cross-sectional area of ​​the second reinforcing portion 223 gradually decreases from the end of the second buckle 22 connected to the main body 21 to the direction of the second limiting portion 222. Through the above arrangement, the connection strength between the first buckle 12 and the bottom plate 11 and the connection strength between the second buckle 22 and the main body 21 can be improved while ensuring the elasticity of the first buckle 12 and the second buckle 22, thereby reducing the rigid stress on the rear shell 10 and the middle frame 20 during assembly and disassembly.

[0069] In one embodiment, Figure 6 and Figure 7 As shown, from the end of the first buckle 12 connected to the bottom plate 11 to the end of the first buckle 12 facing the main body 21, the length A7 of the first buckle 12 ranges from 8 mm to 15 mm. From the end of the second buckle 22 connected to the main body 21 to the end of the second buckle 22 facing the main body 21, the length B7 of the second buckle 22 ranges from 8 mm to 15 mm.

[0070] When the lengths of the first buckle 12 and the second buckle 22 are within the above range, sufficient elasticity can be provided to ensure the convenience of the assembly and disassembly process of the first buckle 12 and the second buckle 22, and a good limiting effect between the first buckle 12 and the second buckle 22 can be ensured when the first buckle 12 and the second buckle 22 are matched, thereby ensuring the stability of the installation of the rear housing 10 and the middle frame 20. In some embodiments, the length of the first buckle 12 can be, for example, 8 mm, 10 mm, 12 mm, 15 mm, etc. The length of the second buckle 22 can be, for example, 8 mm, 10 mm, 12 mm, 15 mm, etc.

[0071] In one embodiment, Figure 6 and Figure 7 As shown, from the edge where the first abutting surface 1221 is connected to the first extension portion 121 to the direction away from the edge of the first extension portion 121, the width C7 of the portion where the first abutting surface 1221 contacts the second abutting surface 2221 ranges from 0.5mm to 1.5mm. In this way, the width of the portion where the first abutting surface 1221 contacts the second abutting surface 2221 is moderate, which can provide sufficient contact area to ensure the stable connection between the rear shell 10 and the middle frame 20, and at the same time make it easier to separate the buckle during disassembly, reduce the force required for disassembly, and avoid damage to the buckle. In some embodiments, the value of the width C7 can be, for example, 0.5mm, 0.8mm, 1.2mm, 1.5mm, etc.

[0072] In one embodiment, Figure 6 and Figure 7 As shown, the value range of the width D7 of the first abutting surface 1221 is 1mm to 1.5mm from the edge where the first abutting surface 1221 is connected to the first extension portion 121 and points to the edge away from the first extension portion 121; the value range of the width E7 of the second abutting surface 2221 is 1mm to 1.5mm from the edge where the second abutting surface 2221 is connected to the second extension portion 221 and points to the edge away from the second extension portion 221. The widths of the first abutting surface 1221 and the second abutting surface 2121 are moderate, which can provide sufficient contact area to ensure the stable connection between the rear shell 10 and the middle frame 20. At the same time, the above-mentioned setting is also conducive to mold design, making it more convenient to demould the rear shell 10 and the middle frame 20, which is conducive to reducing the difficulty of the process. In some embodiments, the values ​​of the width D7 and the width E7 can be, for example, 1mm, 1.2mm, 1.5mm, etc.

[0073] In one embodiment, Figure 6 and Figure 7 As shown, the maximum width F7 of the portion where the first reinforcing portion 123 is connected to the bottom plate 11 is in the range of 3 mm to 15 mm; the maximum width G7 of the portion where the second reinforcing portion 223 is connected to the main body 21 is in the range of 3 mm to 15 mm. The widths of the first reinforcing portion 123 and the second reinforcing portion 223 are moderate, which can not only improve the structural strength of the first buckle 12 and the second buckle 22, but also make the design more compact and reduce material waste. In some embodiments, the values ​​of the width F and the width G can be, for example, 1 mm, 1.2 mm, 1.5 mm, etc.

[0074] In one embodiment, Figure 1 As shown, the bottom plate 11 includes two opposite first edge areas 111 and two opposite second edge areas 112. The first edge area 111 extends along a first direction X, and the second edge area 112 extends along a second direction Y, and the first direction X intersects with the second direction Y. At least one of the first edge areas 111 and at least one of the second edge areas 112 are respectively provided with a plurality of first buckles 12 arranged at even intervals. By respectively providing a plurality of first buckles 12 on the first edge area 111 and the second edge area 112, multi-point fixation can be achieved, thereby improving the overall structural stability of the rear shell 10 and the middle frame 20. In some embodiments, the two first edge areas 111 and the two second edge areas 112 are respectively provided with a plurality of first buckles 12.

[0075] Figure 1In the illustrated embodiment, the plurality of first buckles 12 in the upper first edge region 111 are evenly spaced and arranged, and the plurality of first buckles 12 in the two second edge regions 112 are evenly spaced and arranged.

[0076] In one embodiment, the first direction X is perpendicular to the second direction Y. The first direction X is the length direction of the bottom plate 11 , and the second direction Y is the width direction of the bottom plate 11 .

[0077] In one embodiment, Figure 1 As shown, the multiple first buckles 12 arranged in the first edge area 111 are evenly spaced along the first direction X, and the distance D1 between two adjacent first buckles 12 ranges from 50mm to 150mm; the multiple first buckles 12 arranged in the second edge area 112 are evenly spaced along the second direction Y, and the distance B1 between two adjacent first buckles 12 ranges from 50mm to 150mm. With such a configuration, the spacing between the first buckles 12 is moderate, which can ensure sufficient matching force at the edge of the display device, avoid gaps at the edge of the display device due to excessive spacing between the first buckles 12, and reduce unnecessary material usage and manufacturing costs. In some embodiments, the value of the distance D1 can be, for example, 50mm, 80mm, 120mm, 150mm, etc., and the value of the distance B1 can be, for example, 50mm, 80mm, 120mm, 150mm, etc. In one embodiment, as Figure 1 As shown, among the plurality of first buckles 12 disposed in the first edge region 111, the first buckle 12 having the smallest first distance to the outer edge of the second edge region 112 extending along the second direction Y is the first buckle 1201, and the first distance C1 from the first buckle 1201 to the outer edge of the second edge region 112 ranges from 20 mm to 100 mm. Figure 1 In the illustrated embodiment, among the multiple first buckles 12 in the first edge region 111, the distance between the first buckle 12 located on the leftmost side and the left edge of the bottom plate 11 is the first distance C1, and the distance between the first buckle 12 located on the rightmost side and the right edge of the bottom plate is the first distance C1. Through the above arrangement, it is possible to avoid the above first distance C1 being too large to cause insufficient matching force at the corner of the rear shell 10 and the middle frame 20, and to prevent a gap from appearing at the corner of the rear shell 10 and the middle frame 20. In some embodiments, the value of the first distance C1 can be, for example, 20 mm, 60 mm, 80 mm, 100 mm, etc.

[0078] In one embodiment, Figure 1As shown, among the multiple first buckles 12 arranged in the second edge region 112, the first buckle 12 having the smallest second distance from the outer edge of the first edge region 111 extending along the first direction X is the first buckle 1202, and the second distance A1 from the first buckle 1202 to the outer edge of the first edge region 111 ranges from 20 mm to 100 mm. Figure 1 In the illustrated embodiment, among the multiple first buckles 12 in the second edge region 112, the distance between the topmost first buckle 12 and the upper edge of the bottom plate 11 is the second distance A1, and the distance between the bottommost first buckle 12 and the lower edge of the bottom plate 11 is the second distance A1. Through the above arrangement, insufficient corner matching force caused by the large distance between the first buckle 12 and the edge of the bottom plate 11 can be avoided, and a gap can be prevented from appearing at the corner of the rear shell 10 and the middle frame 20. In some embodiments, the value of the second distance A1 can be, for example, 20 mm, 60 mm, 80 mm, 100 mm, etc.

[0079] In one embodiment, Figure 1 As shown, a first edge area 111 of the bottom plate 11 includes an electronic component area 1111, and the electronic component area 1111 is used to place electronic components, for example, for placing a camera module, and first buckles 12 are respectively provided on both sides of the electronic component area; the third distance E1 between the two first buckles 12 located on both sides of the electronic component area and adjacent to the electronic component area 1111 has a value range of 100mm to 150mm. With such a setting, while ensuring sufficient edge matching force of the display device, there is enough space in the camera module area to avoid the camera being unable to be installed or work properly due to the first buckle 12 being too close. In some embodiments, the value of the third distance E1 can be, for example, 100mm, 120mm, 130mm, 150mm, etc.

[0080] Further, when the first edge region 111 includes the electronic component area 1111, the multiple first buckles 12 located on the same side of the electronic component area 1111 are evenly spaced, and the distance between two adjacent first buckles ranges from 50 mm to 150 mm, for example, 50 mm, 80 mm, 120 mm, 150 mm, etc. In the embodiment of the present application, since the first buckle 12 and the second buckle 22 are arranged one-to-one, the position of the second buckle 22 on the main body 21 corresponds to the position of the first buckle 12 on the bottom plate 11, which will not be repeated here.

[0081] In one embodiment, Figure 3 and Figure 8As shown, one of the middle frame 20 and the rear shell 10 is provided with a plurality of first positioning portions 13, and the other is provided with a plurality of second positioning portions 23, one of the first positioning portion 13 and the second positioning portion 23 is a positioning protrusion, and the other is a positioning groove, and each of the positioning protrusions is positioned in one of the positioning grooves. Through the cooperation of the first positioning portion 13 and the second positioning portion 23, it can be ensured that the rear shell 10 and the middle frame 20 are accurately aligned during assembly, and the misalignment of the first buckle 12 and the second buckle 22 caused by inaccurate alignment during cooperation can be reduced. Figure 8 In the embodiment shown, the rear shell 10 is provided with a positioning groove, and the middle frame 20 is provided with a positioning protrusion. In other embodiments, the rear shell 10 may be provided with a positioning protrusion, and the middle frame 20 may be provided with a positioning groove.

[0082] In one embodiment, Figure 3 As shown, the middle frame 20 includes two opposite third edge regions 211 and two opposite fourth edge regions 212, the third edge region 211 extends along the first direction X, the fourth edge region 212 extends along the second direction Y, and the first direction X intersects with the second direction Y. At least one of the third edge regions 211 and at least one of the fourth edge regions 212 are respectively provided with a plurality of second positioning portions 23 arranged at even intervals. The plurality of second positioning portions 23 are respectively provided on the third edge region 211 and the fourth edge region 212, so that multi-point positioning can be achieved, thereby improving the accuracy of the assembly of the rear shell 10 and the middle frame 20. In some embodiments, a plurality of second positioning portions 23 are respectively provided in the two third edge regions 211 and the two fourth edge regions 212, and the second positioning portions 23 in the two opposite third edge regions 211 are symmetrically arranged, and the second positioning portions 23 in the two opposite fourth edge regions 212 are symmetrically arranged. The second positioning portions 23 in each third edge region 211 are evenly arranged, and the second positioning portions 23 in each fourth edge region 212 are evenly arranged.

[0083] In one embodiment, Figure 3As shown, at least one of the third edge regions 211 is provided with a plurality of second positioning portions 23 arranged uniformly at intervals along the first direction X, and the distance E3 between two adjacent second positioning portions 23 is in the range of 30 mm to 100 mm. At least one of the fourth edge regions 212 is provided with a plurality of second positioning portions 23 arranged uniformly at intervals along the second direction Y, and the distance B3 between two adjacent second positioning portions 23 is in the range of 30 mm to 100 mm. In this way, the spacing of the second positioning portions 23 is moderate, which can ensure that each second positioning portion 23 can effectively play a positioning role, avoiding positioning failure caused by too large spacing or design redundancy and over-positioning caused by too small spacing. In some embodiments, the value of the distance E can be, for example, 30 mm, 60 mm, 80 mm, 100 mm, etc., and the value of the distance B3 can be, for example, 30 mm, 60 mm, 80 mm, 100 mm, etc.

[0084] In one embodiment, Figure 3 As shown, among the plurality of second positioning portions 23 disposed in the third edge region 211, the second positioning portion 23 having the smallest first distance from the outer edge of the fourth edge region 212 extending along the second direction Y is the second positioning portion 2301, and the first distance D3 from the second positioning portion 2301 to the outer edge of the fourth edge region 212 ranges from 20 mm to 80 mm. Figure 3 In the illustrated embodiment, among the plurality of second positioning portions 23 in the third edge region 211, the distance between the second positioning portion 23 located on the far left and the left edge of the main body 21 is the first distance D3, and the distance between the second positioning portion 23 located on the far right and the right edge of the main body 21 is the first distance D3. Through the above arrangement, it is possible to avoid the above first distance D3 being too large to cause positioning failure or the distance being too small to cause the difficulty of disassembly due to the tight fit at the corners of the middle frame. In some embodiments, the value of the first distance D3 can be, for example, 20 mm, 60 mm, 80 mm, 100 mm, etc.

[0085] In one embodiment, Figure 3 As shown, among the plurality of second positioning portions 23 disposed in the fourth edge region 212, the second positioning portion 23 having the smallest second distance from the outer edge of the third edge region extending along the first direction X is the second positioning portion 2302, and the second distance A3 from the second positioning portion 2302 to the outer edge of the third edge region 211 ranges from 20 mm to 80 mm.

Through the above arrangement, it is possible to avoid the second positioning portion 23 and the corner of the middle frame being too far away from each other, resulting in positioning failure, or the distance being too short, resulting in difficulty in disassembly due to tight fit at the corner of the middle frame. In some embodiments, the value of the first distance A3 can be, for example, 20 mm, 60 mm, 80 mm, 100 mm, etc.

[0086] Since the first positioning portion 13 and the second positioning portion 23 are disposed in one-to-one correspondence, the size and position of the first positioning portion 13 on the rear shell 10 are the same as the size and position of the second positioning portion 23 on the middle frame 20 , which will not be described in detail.

[0087] In one embodiment, Figure 8 As shown, the rear shell further includes a side plate 14 connected to the edge of the bottom plate 11 and extending toward the main body, and the first positioning portion 13 is a positioning groove, which is arranged at one end of the side plate 14 away from the bottom plate 11.

When assembling the rear shell 10 and the middle frame 20, the positioning groove of the side plate 14 can be first contacted with the positioning protrusion of the side portion 24 to complete the positioning, and then pressure is applied to match the first buckle 12 on the bottom plate 11 with the second buckle 22 on the main body 21, so as to avoid the first buckle 12 and the second buckle 22 from being misaligned when assembling the rear shell 10 and the middle frame 20. In other embodiments, the first positioning portion 13 is directly disposed on the surface of the bottom plate 11 facing the main body 21, and the second positioning portion 23 is directly disposed on the surface of the main body 21 facing the bottom plate 11.

The distance B9 between the first side surface 231 and the second side surface 232 of the positioning protrusion 23 and the inner surface of the positioning groove 13 located on the same side has a value range of 0.5 mm to 1 mm. The distance C9 between the third side surface 233 of the positioning protrusion 23 and the inner surface of the positioning groove 13 located on the same side has a value range of 0.1 mm to 0.3 mm, and the distance D9 between the fourth side surface 234 of the positioning protrusion 23 and the inner surface of the positioning groove 13 located on the same side has a value range of 0.5 mm to 1 mm. Through the above arrangement, it can be ensured that the gap between the positioning protrusion 23 and the positioning groove 13 is moderate, avoiding the difficulty of assembly due to a gap that is too small, or the loss of positioning function due to a gap that is too large.

[0089] In some embodiments, the value of distance B9 can be, for example, 0.5 mm, 0.8 mm, 1 mm, etc.; the value of distance C can be, for example, 0.1 mm, 0.2 mm, 0.3 mm, etc.; the value of distance D9 can be, for example, 0.5 mm, 0.8 mm, 1 mm, etc.

One of the support plate 40 and the middle frame 20 is provided with a first limiting structure 42, and the other is provided with a second limiting structure 25. One of the first limiting structure 42 and the second limiting structure 25 is a limiting protrusion, and the other is a limiting hole. Each limiting protrusion is located in one of the limiting holes. Through the cooperation of the first limiting structure 42 and the second limiting structure 25, it can be ensured that the relative position of the support plate 40 and the middle frame 20 is stable during assembly, avoiding local deformation of the middle frame 20, and thus preventing the position offset between the buckles when the middle frame 20 is subsequently assembled with the rear shell 10.

[0093] In one embodiment, Fig.11 As shown, the support plate 40 includes two opposite fifth edge regions 411 and two opposite sixth edge regions 412.

In this way, the spacing of the first limiting structures 42 is moderate, which can ensure that each first limiting structure 42 can effectively play a limiting role, avoiding positioning failure caused by too large spacing or design redundancy and over-positioning caused by too small spacing. In some embodiments, the value of the distance D11 can be, for example, 50 mm, 60 mm, 80 mm, 100 mm, etc., and the value of the distance B11 can be, for example, 50 mm, 60 mm, 80 mm, 100 mm, etc.

Through the above arrangement, it is possible to avoid the positioning failure caused by the distance between the first limiting structure 42 and the corner of the support plate 40 being too large, or the difficulty in disassembly caused by the close fit between the corners of the support plate 40 and the middle frame being too small. In some embodiments, the value of the first distance C11 may be, for example, 20 mm, 60 mm, 80 mm, 100 mm, etc., and the value of the first distance A11 may be, for example, 20 mm, 60 mm, 80 mm, 100 mm, etc.

Through the above arrangement, it can be ensured that the gap between the limiting protrusion 42 and the limiting hole 25 is moderate, avoiding the difficulty of assembly due to a gap that is too small, or the loss of the limiting effect due to a gap that is too large.

[0103] In some embodiments, the value of distance B14 can be, for example, 0.5 mm, 0.8 mm, 1 mm, etc.; the value of distance C can be, for example, 0.5 mm, 0.8 mm, 1 mm, etc.; the value of distance D can be, for example, 0.1 mm, 0.2 mm, 0.3 mm, etc.

With such a configuration, the border of the display device can be made narrower, thereby increasing the screen-to-body ratio of the display device and providing a better visual experience for the user. Preferably, the microphone circuit board is arranged vertically to the bottom plate 11, thereby further reducing the border width of the display device.

[0106] It should be noted that the angle between the microphone circuit board 61 and the bottom plate 11 is an acute angle or a right angle, which means that the angle between the surface of the microphone circuit board 61 provided with the sound pickup sensor 62 and the surface of the bottom plate 11 facing the middle frame is an acute angle or a right angle.

[0107] In one embodiment, the microphone module 60 is disposed in the electronic component area of ​​the first edge region.
