Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background Art

[0002] At present, in the design of electronic products, a snap-on solution is often used to fix two structural parts, such as between the battery back cover and the motherboard bracket. When the snap-on is located at the edge of the two structural parts, the snap-on can be seen when the two structural parts are snap-connected, and then it can be confirmed whether the snap-on is in place. However, when the snap-on is in the middle area of ​​the two structural parts, the two structural parts are snap-connected, and there will be a blind snapping scenario because the snap-on cannot be seen. It is impossible to accurately identify whether the snap-on is assembled in place, which will affect the stability of the assembly of the two structural parts. Summary of the invention

[0003] The present application provides an electronic device to solve the technical problem in the prior art that two structural parts in the electronic device are blindly fastened, resulting in the inability to identify whether they are fastened in place.

[0004] The technical solution is as follows:

[0005] The present application provides an electronic device, including a buckle structure and two or more structural members, wherein:

[0006] The buckle structure includes a first buckle and a second buckle engaged with the first buckle, and the first buckle and the second buckle are respectively arranged on two structural members;

[0007] A visible opening is provided on the structural member on which the first buckle is provided or on the structural member on which the second buckle is provided, and a reference mark is provided on the structural member on which the second buckle is provided;

[0008] When the first buckle and the second buckle are assembled in place, the reference mark is aligned with the first buckle.

[0009] The electronic device provided in this embodiment adds a visual opening and a reference mark on the structural member, and observes whether the first buckle is aligned with the reference mark through the visual opening, so that it can visually check whether the first buckle and the second buckle are in place after assembly, thereby avoiding the existing problem of being unable to confirm whether the buckles are assembled in place.

[0010] In some implementations, the first buckle includes a first connecting arm and a first hook, the first hook is disposed at one end of the first connecting arm, and the other end of the first connecting arm is connected to the corresponding structural member.

[0011] The structure of the first buckle provided in this implementation is conducive to matching with the reference mark, and whether the first buckle and the second buckle are properly engaged can be judged by observing whether the first connecting arm is aligned with the reference mark.

[0012] In some implementations, the second buckle includes a buckle opening, the first connecting arm passes through the buckle opening, and the first hook abuts against a structural member on which the second buckle is provided.

[0013] The second buckle provided in this implementation has a simple structure and is convenient for connecting the first buckle to the second buckle.

[0014] In some implementations, the snap-on structure includes a third snap-on, and the third snap-on and the first snap-on are arranged on the same structural member. The first snap-on and the third snap-on respectively correspond to a reference mark. When the third snap-on and the second snap-on are assembled in place, the third snap-on is aligned with the reference mark corresponding thereto.

[0015] In this implementation, the first buckle and the third buckle both cooperate with the same second buckle, so that the two structural members are stably connected through the buckle structure.

[0016] In some implementations, the second hook further includes a hook protrusion abutting against the first hook.

[0017] In this implementation, the first buckle is facilitated to further tightly fit on the second buckle.

[0018] In some implementations, the first hook includes a connecting surface and a facing surface, the connecting surface and the facing surface are arranged opposite to each other, the connecting surface is connected to the first connecting arm, and one of the edges of the facing surface is chamfered.

[0019] In this implementation, a chamfer is provided on the first hook to facilitate assembly of the first buckle and the second buckle.

[0020] In some implementations, the second buckle includes a second connecting arm and a second hook, the second hook is connected to the second connecting arm, and the other end of the second connecting arm is connected to the corresponding structural member.

[0021] The structure of the second buckle provided in this implementation can reduce the length of the first connecting arm in the first buckle and improve the strength of the first buckle.

[0022] In some implementations, the first connecting arm includes two opposite first side surfaces and a second side surface, and the first hook is disposed on the first side surface. When the first hook and the second hook are assembled in place, the reference mark is aligned with the first side surface; or, the reference mark is aligned with the second side surface; or, the reference mark is aligned with both the first side surface and the second side surface.

[0023] In this implementation, by using the first side surface and / or the second side surface of the first buckle to cooperate with the reference mark, it can be quickly determined whether the first buckle and the second buckle are snapped into place.

[0024] In some implementations, the reference marker is a straight line, and the reference marker matches the first side surface or the second side surface; or, the reference marker is two parallel straight lines arranged at intervals, and the two parallel straight lines match the first side surface and the second side surface respectively; or, the reference marker is a rectangle, and the two opposite sides of the reference marker match the first side surface and the second side surface respectively.

[0025] In this implementation, the reference mark has a simple shape and is easy to process.

[0026] In some implementations, two reference marks are provided on a structural member on which the second buckle is provided, and the two reference marks are respectively located on two sides of the first buckle.

[0027] In this embodiment, two reference marks are provided to facilitate further confirmation of whether the first buckle is properly installed on the second buckle.

[0028] In some implementations, the reference mark is a groove or a hole; or, the reference mark is a textured surface; or, the reference mark is a silk-screen pattern.

[0029] The reference marks provided by this implementation method can realize rapid processing of reference marks on structural parts.

[0030] In some implementations, the structural components of the electronic device include a mainboard bracket, a battery rear cover, and a front housing component, and the battery rear cover and the front housing component are located on both sides of the mainboard bracket.

[0031] In some implementations, a snap-fit ​​structure is provided between the battery rear cover and the mainboard bracket, and / or a snap-fit ​​structure is provided between the front housing member and the mainboard bracket.

[0032] In this implementation, the mainboard brackets are fixed with a snap-on structure to facilitate the mainboard brackets to be connected in place.

[0033] In some implementations, the front housing member is an integrally formed member; the front housing member forms a side surface of the electronic device along a circumferential direction; or, the battery rear cover forms a side surface of the electronic device along a circumferential direction.

[0034] In some implementations, the front housing member includes a rear middle frame and a front housing, and a snap-fit ​​structure is provided between the rear middle frame and the front housing.

[0035] In this implementation, by setting the buckle structure in this embodiment between the rear middle frame and the front shell, it is possible to visually check whether the first buckle and the second buckle are in place after assembly, so as to facilitate the connection of the rear middle frame and the front shell.

[0036] In some implementations, the battery back cover is a structural member on which the first buckle is disposed, a camera matching area is formed on the battery back cover, and the visible opening is located in the camera matching area.

[0037] In this implementation, the visual opening is located in the camera mating area, which not only allows visual inspection of whether the first buckle and the second buckle on the mainboard bracket and the battery back cover are buckled in place after assembly, but also the subsequent assembly of the transparent glass on the battery back cover will not affect the waterproof effect of the battery back cover on the internal mainboard and battery, and will not affect the aesthetics.

[0084] Before explaining the electronic device 100 provided in the embodiment of the present application in detail, the existing related technologies and scenarios are first explained.

[0085] At present, in the electronic device 100, the fixing between two structural parts often adopts a buckle solution. Taking the electronic device 100 as a mobile phone as an example, Figure 1-Figure 2 is a schematic diagram of a mobile phone in the related art, wherein: Figure 1 The back side of the mobile phone is shown in FIG. Figure 2 Schematic diagram of the explosion of a mobile phone.

[0086] See also Figure 2The mobile phone generally includes a display screen 1 and a housing, the housing includes a middle frame 2 and a battery back cover 3, the display screen 1 and the battery back cover 3 are arranged on both sides of the middle frame 2, that is, the display screen 1, the middle frame 2 and the battery back cover 3 are arranged in sequence along the thickness direction of the mobile phone, and the display screen 1, the middle frame 2 and the battery back cover 3 are surrounded to form a containing space. Figure 2 The mobile phone also includes a mainboard 4, a mainboard bracket 5 and a battery ( Figure 2 The mainboard 4 is fixed on the mainboard bracket 5, see Figure 3 , showing an exploded schematic diagram of the existing related motherboard 4 and motherboard bracket 5, see Figure 2 The motherboard bracket 5 is arranged between the middle frame 2 and the battery back cover 3 , the motherboard 4 is located on the side of the motherboard bracket 5 away from the battery back cover 3 , and the motherboard bracket 5 is fixed on the battery back cover 3 and the middle frame 2 .

[0087] The mainboard bracket 5 and the battery back cover 3 are usually fixed by a snap-fit ​​structure, and the mainboard bracket 5 and the middle frame 2 are also usually fixed by a snap-fit ​​structure.

[0088] See also Figure 4-Figure 6 , Figure 4 It is a schematic diagram of an existing related motherboard bracket 5 connected to the middle frame 2; Figure 5 Another schematic diagram of the existing related motherboard bracket 5 connected to the middle frame 2; Figure 5 yes Figure 4 Partial cross-sectional view at AA in the middle.

[0089] See also Figure 4 and Figure 6 , a male buckle 6 is provided on the middle frame 2, and a female buckle 7 is provided on the motherboard bracket 5. Please refer to Figure 5 , from the side of the middle frame 2 away from the motherboard bracket 5 Figure 6 On the side a pointed by the middle arrow, the male buckle 6 on the middle frame 2 and the female buckle 7 on the motherboard bracket 5 cannot be seen. Figure 4 , from the side of the mainboard bracket 5 away from the middle frame 2 Figure 4 On the side b pointed by the middle arrow, the male buckle 6 on the middle frame 2 and the female buckle 7 of the motherboard bracket 5 are not visible. When the female buckle 7 on the motherboard bracket 5 is buckled onto the male buckle 6 on the middle frame 2, since the female buckle 7 and the male buckle 6 are not visible, it is a blind buckle. In the case of blind buckle, it is impossible to accurately identify whether the female buckle 7 and the male buckle 6 are assembled in place. If the female buckle 7 and the male buckle 6 are not assembled in place, the female buckle 7 and the male buckle 6 will be easily separated, which will affect the assembly of the middle frame 2 and the motherboard bracket 5 and the stability of the connection between the two.

[0090] See also Figure 5 , Figure 5The schematic diagram in the middle is a schematic diagram of the male buckle 6 being connected to the female buckle 7. The male buckle 6 includes a male buckle connecting arm 61 and a male buckle hook 62. The female buckle 7 includes a female buckle connecting arm 71 and a female buckle hook 72. Figure 5 In the embodiment, the male buckle connecting arm 61 of the male buckle 6 is connected with the female buckle hook 72 of the female buckle 7.

[0091] See also Figure 7 , which illustrates a schematic diagram of the assembly process of a female buckle 7 and a male buckle 6 of an existing related structure. Figure 7 (a) shows the state where the male buckle 6 and the female buckle 7 are not in contact; Figure 7 (b) in the figure shows the state where the male buckle 6 and the female buckle 7 just come into contact, that is, as the female buckle 7 gradually moves downward, the male buckle connecting arm 61 of the male buckle 6 will come into contact with the female buckle hook 72 of the female buckle 7; see Figure 7 (c) in the figure shows the elastic deformation state of the male buckle connecting arm 61 of the male buckle 6 and the female buckle connecting arm 71 of the female buckle 7, that is, as the female buckle 7 continues to move downward, the male buckle connecting arm 61 of the male buckle 6 and the female buckle connecting arm 71 of the female buckle 7 will be elastically deformed under the squeeze between the male buckle hook 62 of the male buckle 6 and the female buckle hook 72 of the female buckle 7; if the female buckle 7 continues to move downward, the female buckle 7 and the male buckle 6 will be as shown in the figure. Figure 7 In the state shown in (d), the male buckle connecting arm 61 of the male buckle 6 and the female buckle connecting arm 71 of the female buckle 7 continue to elastically deform, and the male buckle first side surface 621 on the male buckle hook 62 is in contact with the female buckle first side surface 721 of the female buckle hook 72. In this state, the female buckle 7 and the male buckle 6 are still not assembled in place; see Figure 7 (e) is a schematic diagram of the female buckle 7 and the male buckle 6 being assembled in place, at which time the male buckle connecting arm 61 of the male buckle 6 and the female buckle connecting arm 71 of the female buckle 7 are reset.

[0092] When the female buckle 7 on the mainboard bracket 5 is buckled onto the male buckle 6 on the middle frame 2, since the female buckle 7 and the male buckle 6 cannot be seen, when it is believed that the female buckle 7 and the male buckle 6 are assembled, there is actually a gap between the male buckle 6 and the female buckle 7. Figure 7 The state shown in (d) is possible, in which the female buckle 7 and the male buckle 6 are not assembled in place, and the female buckle 7 and the male buckle 6 are easily separated under the action of external force, which will affect the stability of the connection between the middle frame 2 and the mainboard bracket 5.

[0093] Therefore, in order to solve the above technical problems, the present application provides an electronic device 100, by providing a visual opening 10 on a structural member 9 on which a first buckle 81 or a second buckle 82 is provided, the first buckle 81 can be observed through the visual opening 10, and a reference mark 11 is provided on the structural member 9 on which the second buckle 82 is provided. During the process of assembling the first buckle 81 and the second buckle 82, the position of the first buckle 81 and the reference mark 11 can be observed to determine the engagement of the first buckle 81 and the second buckle 82. If the first buckle 81 is aligned with the reference mark 11, it means that the first buckle 81 and the second buckle 82 are engaged in place. That is, the present application can visually inspect whether the first buckle 81 and the second buckle 82 are engaged in place after assembly by adding a visual opening 10 and a reference mark 11 on the structural member 9, thereby avoiding the problem that the existing related problems cannot confirm whether the buckles are assembled in place.

[0094] The electronic device 100 provided in the embodiment of the present application is explained in detail below with reference to the accompanying drawings.

[0095] The electronic device 100 provided in this embodiment includes, but is not limited to, a cell phone, a notebook computer, a tablet personal computer, a laptop computer, a personal digital assistant, a wearable device, a mobile device, or a Bluetooth speaker. In the embodiment of the present application, the electronic device 100 is described as a mobile phone.

[0096] When the electronic device 100 is a mobile phone, it can be a foldable mobile phone or a non-foldable mobile phone. The following description takes the electronic device 100 as a non-foldable mobile phone as an example.

[0097] The length direction of the electronic device 100 is defined as the X-axis direction, the width direction of the electronic device 100 is defined as the Y-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. Along the X-axis direction, the two ends of the electronic device 100 are defined as the top end and the bottom end, respectively.

[0098] See also Figure 8-Figure 10 , Figure 8 Schematic diagram of an explosion of an electronic device 100 provided in an embodiment of the present application ( Figure 8 The battery of the electronic device 100 is not shown); Fig. 9 for Figure 8 A partial enlarged view of the middle A; Fig.10 for Figure 8 A schematic cross-sectional view of the middle buckle structure 8.

[0099] The electronic device 100 provided in this embodiment includes a buckle structure 8 and two or more structural members 9 .

[0100] The structural components 9 of the electronic device 100 refer to the mechanical and physical components constituting the electronic device 100 , which provide the electronic device 100 with functions such as support, protection, connection and appearance.

[0101] For example, in one scenario, see Figure 8 The electronic device 100 includes a display screen 1, a middle frame 2, a battery back cover 3, a motherboard bracket 5, a battery, etc. The middle frame 2 and the battery back cover 3 form a housing of the electronic device 100. The middle frame 2, the battery back cover 3, and the motherboard bracket 5 are all structural components 9 of the electronic device 100. In addition, Figure 8 The figure shows the partial structure of the display screen 1, the middle frame 2, and the battery back cover 3.

[0102] The buckle structure 8 provided in this embodiment can be set as one, which can be applied between the mainboard bracket 5 and the battery back cover 3 or between the mainboard bracket 5 and the battery back cover 3, see Fig. 9 , indicating that a buckle structure 8 is provided between the mainboard bracket 5 and the mainboard bracket 5. Alternatively, two buckle structures 8 may be provided, and illustratively, two buckle structures 8 are respectively applied between the mainboard bracket 5 and the battery back cover 3 and between the mainboard bracket 5 and the middle frame 2; of course, more than three buckle structures may also be provided to respectively connect different structural members 9 in the electronic device 100.

[0103] In addition, for two structural members 9 provided with snap-fit ​​structures 8, one snap-fit ​​structure 8 may be provided between the two structural members 9, or more than two snap-fit ​​structures 8 may be provided between the two structural members 9, that is, a reasonable number of snap-fit ​​structures 8 may be provided between the two structural members 9 according to requirements.

[0104] The buckle structure 8 provided in this embodiment, see Fig.10 The buckle structure 8 includes a first buckle 81 and a second buckle 82 engaged with the first buckle 81. The first buckle 81 and the second buckle 82 are respectively arranged on two structural members 9. For the convenience of description, the structural member 9 provided with the first buckle 81 is referred to as the first structural member 91, and the structural member 9 provided with the second buckle 82 is referred to as the second structural member 92. Fig.10 , schematically showing that the first buckle 81 is located on the first structural member 91, and the second buckle 82 is located on the second structural member 92. Through the buckle structure 8, the structural member 9 provided with the first buckle 81 and the structural member 9 provided with the second buckle 82 can be connected.

[0105] In this embodiment, a visualization opening 10 may be provided on the structural member 9 provided with the first buckle 81, or a visualization opening 10 may be provided on the structural member 9 provided with the second buckle 82, so that the first buckle 81 can be observed through the visualization opening 10. Fig.10 , schematically illustrating that a visual opening 10 is provided on the structural member 9 provided with the second buckle 82 , that is, a visual opening 10 is provided on the second structural member 92 , through which the first buckle 81 can be seen.

[0106] Specifically, according to the structure of the second buckle 82 and the structure of the two structural members 9 with the first buckle 81 and the second buckle 82, it can be selected whether to set the visual opening 10 on the structural member 9 with the first buckle 81 or to set the visual opening 10 on the structural member 9 with the second buckle 82.

[0107] In this embodiment, see Fig.10 , a reference mark 11 is set on the structural member 9 where the second buckle 82 is set, and when the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 11 is aligned with the first buckle 81. Fig.10 , illustrates a reference mark 11 , which is located on the structural member 9 on which the second buckle 82 is provided, that is, the second structural member 92 .

[0108] The reference mark 11 is aligned with the first buckle 81 , that is, when the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 11 is aligned with the surface on the first buckle 81 .

[0109] During the process of connecting the first buckle 81 to the second buckle 82, the first buckle 81 and the reference mark 11 can be observed through the visual opening 10. During the process of connecting the first buckle 81 to the second buckle 82, the first buckle 81 will be elastically deformed, and the elastically deformed first buckle 81 will not be aligned with the reference mark 11; and when the first buckle 81 is completely buckled on the second buckle 82, that is, the first buckle 81 and the second buckle 82 are fully assembled, the reference mark 11 is aligned with the first buckle 81. See Fig.10 , indicating that the reference mark 11 is aligned with the side surface of the first buckle 81.

[0110] The electronic device 100 provided in this embodiment adds a visual opening 10 and a reference mark 11 on the structural member 9, and observes whether the first buckle 81 is aligned with the reference mark 11 through the visual opening 10, so as to visually check whether the first buckle 81 and the second buckle 82 are properly engaged after assembly, thereby avoiding the problem of being unable to confirm whether the buckles are properly assembled in the prior art.

[0111] See also Figure 11-Figure 12 , Fig.11This is a schematic diagram of the structure in which the first buckle 81 is arranged on the first structural member 91 in this embodiment; Fig.12 for Fig.11 A partial enlarged view of point B in the middle.

[0112] In one embodiment, see Fig.12 The first buckle 81 includes a first connecting arm 811 and a first hook 812 . The first hook 812 is arranged at one end of the first connecting arm 811 , and the other end of the first connecting arm 811 is connected to the corresponding structural member 9 .

[0113] When connecting the first buckle 81 to the second buckle 82, the first connecting arm 811 will undergo elastic deformation so that the first hook 812 avoids the second buckle 82. When the first buckle 81 is snapped into place on the second buckle 82, the first connecting arm 811 moves in the resetting direction, and the first hook 812 will hook onto the first buckle 81, thereby realizing the snap connection between the first buckle 81 and the second buckle 82.

[0114] The structure of the first buckle 81 provided in this embodiment is conducive to matching with the reference mark 11. By observing whether the first connecting arm 811 is aligned with the reference mark 11, it can be judged whether the first buckle 81 and the second buckle 82 are in place.

[0115] Exemplarily, the first buckle 81 and the structural member 9 provided with the first buckle 81 are an integrally formed structure.

[0116] Regarding the structure of the first hook 812 in the first buckle 81, in one embodiment, see Fig.12 The first hook 812 includes a connecting surface and a facing surface 8121 , the connecting surface and the facing surface 8121 are arranged opposite to each other, the connecting surface is connected to the first connecting arm 811 , and one of the edges of the facing surface 8121 is formed with a chamfer 8122 .

[0117] In this embodiment, when assembling the first buckle 81 and the second buckle 82, the chamfer 8122 on the first buckle 81 can be first brought into contact with the second buckle 82, and then the first buckle 81 can be gradually pressed down to elastically deform the first connecting arm 811 of the first buckle 81 until the first buckle 81 and the second buckle 82 are snapped into place.

[0118] In this embodiment, the chamfer 8122 is provided on the first hook 812 to facilitate the assembly of the first buckle 81 and the second buckle 82 .

[0119] For example, see Fig.12, illustrating the bottom slope 8123 on the first buckle 81. The side of the first hook 812 away from the first structural member 91 is the bottom slope 8123. From the connecting surface of the first hook 812 to the direction away from the surface 8121, the bottom slope 8123 gradually tilts toward the direction close to the first structural member 91 to facilitate the assembly of the first buckle 81 and the second buckle 82.

[0120] See also Figure 13-Figure 19 , Fig.13 It is a schematic diagram of the structure in which the first buckle 81 is arranged on the first structural member 91; Fig.14 for Fig.13 A partial enlarged view of point C in the middle; Fig.15 The enlarged view of the first side surface 8111 of the first buckle 81 can be seen through the visualization opening 10; Fig.16 An enlarged view of the first side surface 8111 and the second side surface 8112 of the first buckle 81 can be seen through the visualization opening 10; Fig.17 It is a schematic diagram of a structure in which two structural members are connected via a first buckle 81 and a second buckle 82; Fig.18 for Fig.17 A partial enlarged view of point D in the middle; Fig.19 It is an enlarged view showing the alignment of the reference mark 11 with the first side surface 8111 of the first buckle 81 .

[0121] Based on the embodiment in which the first buckle 81 includes a first connecting arm 811 and a first hook 812, in one embodiment, see Fig.13 and Fig.14 The first connecting arm 811 includes a first side surface 8111 and a second side surface 8112 that are arranged opposite to each other. The first side surface 8111 is provided with a first hook 812. When the first hook 81 and the second hook 82 are assembled in place, the reference mark 11 is aligned with the first side surface 8111, or the reference mark 11 is aligned with the second side surface 8112, or both the first side surface 8111 and the second side surface 8112 are aligned with the reference mark 11.

[0122] When a visualization opening 10 is provided on the structural member 9 provided with the first buckle 81, the positions of the openings are different, and the following three situations may occur: first, only the first side surface 8111 is observed through the visualization opening 10; second, only the second side surface 8112 is observed through the visualization opening 10; third, both the first side surface 8111 and the second side surface 8112 are observed through the visualization opening 10. Figure 14-16 , both of which have a visible opening 10 on the structural member 9 (first structural member 91) on which the first buckle 81 is provided, wherein: Fig.14 and Fig.16 It is shown that the first side 8111 and the second side 8112 can be observed through the visualization opening 10. Fig.15It is illustrated that only the first side surface 8111 is observed through the visualization opening 10 .

[0123] When the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 11 is aligned with the first side surface 8111. At this time, the position of the visualization opening 10 allows only the first side surface 8111 to be observed through the visualization opening 10, or allows both the first side surface 8111 and the second side surface 8112 to be observed through the visualization opening 10. Fig.19 , illustrating that both the first side 8111 and the second side 8112 can be observed through the visual opening 10 , but at this time, when the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 11 is aligned with the first side 8111 .

[0124] When the first buckle 81 and the second buckle 82 are assembled into place, the reference mark 11 is aligned with the second side 8112. At this time, the position of the visualization opening 10 allows only the second side 8112 to be observed through the visualization opening 10, or allows both the first side 8111 and the second side 8112 to be observed through the visualization opening 10.

[0125] When the first buckle 81 and the second buckle 82 are assembled in place, the first side surface 8111 and the second side surface 8112 are aligned with the reference mark 11. At this time, a visualization opening 10 can be provided so that both the first side surface 8111 and the second side surface 8112 can be observed through the visualization opening 10. Fig.18 , illustrating that through the visual opening 10, both the first side 8111 and the second side 8112 can be observed. At the same time, when the first buckle 81 and the second buckle 82 are assembled in place, the first side 8111 and the second side 8112 are aligned with the reference mark 11.

[0126] Regarding the alignment of reference mark 11 with the first side surface 8111 or the second side surface 8112, it can be understood that a reference line will be formed on reference mark 11, and the reference line may be the outer contour line of reference mark 11. Of course, the reference line may not be the outer contour line of reference mark 11. By observing whether the reference line is on the same plane as the first side surface 8111 or the second side surface 8112, it can be considered whether reference mark 11 is aligned with the first side surface 8111 or the second side surface 8112.

[0127] Regarding the alignment of the reference mark 11 with the first side surface 8111 and the second side surface 8112, it can be understood that two reference lines will be formed on the reference mark 11. By observing that the two reference lines are respectively on the same plane with the first side surface 8111 and the second side surface 8112, it can be considered that the reference mark 11 is aligned with the first side surface 8111 and the second side surface 8112.

[0128] See also Fig. 20 , which is an enlarged view of the reference mark 11 aligned with the second side surface 8112 of the first buckle 81.

[0129] The above describes three situations that occur when the visible opening 10 is provided on the structural member 9 of the first buckle 81, and the positions of the openings are different. The above records that the visible opening 10 can be provided not only on the structural member 9 provided with the first buckle 81, but also on the structural member 9 provided with the second buckle 82. Fig. 20 , illustrating that the visible opening 10 is opened on the structural member 9 (second structural member 92 ) provided with the second buckle 82 . Fig. 20 It is shown in the figure that when the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 11 is aligned with the second side surface 8112.

[0130] In the case where the visual opening 10 is opened on the structural member 9 provided with the second clip 82, a reference mark 11 can also be provided to cooperate with the first hook 812, that is, when the first clip 81 and the second clip 82 are assembled in place, the reference mark 11 is aligned with the first hook 812.

[0131] In this embodiment, by using the first side surface 8111 and / or the second side surface 8112 of the first buckle 81 to cooperate with the reference mark 11, it can be quickly determined whether the first buckle 81 and the second buckle 82 are snapped into place.

[0132] Regarding the shape of the reference mark 11, based on the embodiment in which the reference mark 11 is aligned with the first side surface 8111 or the second side surface 8112 after the first buckle 81 and the second buckle 82 are assembled in place, in one embodiment, the reference mark 11 is a straight line. Fig.18 and Fig.19 , illustrating that the reference mark 11 is a straight line.

[0133] In this embodiment, the shape of the reference mark 11 is set to be a straight line, and the reference mark 11 is easy to process.

[0134] In this embodiment, see Fig.18 and Fig.19 , a rectangle with a very small width can also be regarded as a straight line, that is, the reference mark 11 can also be a rectangle with a very small width.

[0135] In this embodiment, the reference mark 11 is a straight line, and the reference line can be set as a continuous straight line; or the reference line can be set as a discontinuous straight line, for example, the reference line can be set as a dotted line. Fig.19 , indicating that the reference line is a continuous straight line; see Fig. 20 , indicating that the reference line is a dotted line.

[0136] Regarding the shape of the reference mark 11, based on the embodiment in which the reference mark 11 is aligned with the first side surface 8111 and the second side surface 8112 after the first buckle 81 and the second buckle 82 are assembled in place, in one embodiment, see Fig.18 , reference mark 11 is two parallel straight lines arranged at intervals, and the two parallel straight lines are respectively matched with the first side surface 8111 and the second side surface 8112.

[0137] In this embodiment, the reference mark 11 is set as two parallel straight lines arranged at intervals, and the reference mark 11 is easy to process.

[0138] In this embodiment, a rectangle with a very small width can also be regarded as a straight line, that is, the straight line in the reference mark 11 can also be a rectangle with a very small width.

[0139] In this embodiment, the straight line in the reference mark 11 can be set as a continuous straight line; or, the straight line in the reference mark 11 can also be set as a discontinuous straight line.

[0140] Regarding the shape of the reference mark 11, based on the embodiment in which the reference mark 11 is aligned with the first side surface 8111 and the second side surface 8112 after the first buckle 81 and the second buckle 82 are assembled in place, in another embodiment, see Fig.21 The reference mark 11 is a rectangle, and the two opposite sides of the reference mark 11 match the first side surface 8111 and the second side surface 8112 respectively.

[0141] In this embodiment, the reference mark 11 is set to be a rectangle, and the reference mark 11 is easy to process.

[0142] See also Figure 22-Figure 23 , Fig. 22 A schematic diagram illustrating connecting two structural members through a first buckle 81 and a second buckle 82 is shown; Fig.23 for Fig. 22 A partial enlarged view of point F in the middle.

[0143] In one embodiment, see Fig. 22 and Fig.23 Two reference marks 11 are provided on the structural member 9 on which the second buckle 82 is provided, and the two reference marks 11 are respectively located on both sides of the first buckle 81 .

[0144] In this embodiment, two reference marks 11 are provided to facilitate further confirmation of whether the first buckle 81 is properly installed on the second buckle 82 .

[0145] In this embodiment, the reference marks 11 located on both sides of the first buckle 81 can be set to have the same shape or different shapes.

[0146] In this embodiment, the reference marks 11 located on both sides of the first buckle 81 are respectively called reference mark 1 and reference mark 2. When the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 1 is aligned with the first side 8111, or the reference mark 1 is aligned with the second side 8112, or the first side 8111 and the second side 8112 are aligned with the reference mark 1. When the first buckle 81 and the second buckle 82 are assembled in place, the reference mark 2 is aligned with the first side 8111, or the reference mark 2 is aligned with the second side 8112, or the first side 8111 and the second side 8112 are aligned with the reference mark 2.

[0147] Exemplarily, reference mark 1 and reference mark 2 are on different sides of the first buckle 81. For example, when the first buckle 81 and the second buckle 82 are assembled in place, reference mark 1 is aligned with the second side 8112, and reference mark 2 is aligned with the first side 8111.

[0148] Exemplarily, reference mark 1 and reference mark 2 are the same as the side that matches the first buckle 81. For example, when the first buckle 81 and the second buckle 82 are assembled in place, the first side 8111 and the second side 8112 are aligned with reference mark 1, and the first side 8111 and the second side 8112 are aligned with reference mark 2.

[0149] Regarding the processing of the reference mark 11, in one embodiment, the reference mark 11 is a groove or a hole; in another embodiment, the reference mark 11 is a textured surface; in another embodiment, the reference mark 11 is a silk-screen pattern.

[0150] In the embodiment where the reference mark 11 is a groove or a hole, if the structural member 9 is an injection-molded member, it can be formed by injection molding; or, the groove or the hole can be machined on the structural member 9 by using machining equipment.

[0151] In the embodiment where reference mark 11 is a textured surface, the processing methods of the textured surface on the structural member 9 include mechanical processing, chemical etching, laser processing, embossing, etc. For example, laser processing is used to use a laser beam to ablate or engrave on the surface of the structural member 9 to create the desired textured surface.

[0152] In the embodiment where reference mark 11 is a silk-screen pattern, the silk-screen pattern is a pattern produced by screen printing technology, which uses a silk screen as a printing tool to transfer ink or pigment to the surface of an object through tiny holes to form a pattern.

[0153] The reference mark 11 provided in this embodiment is easy to process, that is, the reference mark 11 can be quickly processed on the structural member 9.

[0154] See also Figure 24-26 , Fig.24A schematic diagram of a first buckle 81 and a second buckle 82 connecting two structural members 9; Fig.25 for Fig.24 A partial enlarged view of point E in the middle; Fig.26 It is a partial enlarged view showing that the first buckle 81 and the third buckle 83 cooperate with the second buckle 82 .

[0155] Based on the embodiment in which the first buckle 81 includes the first connecting arm 811 and the first hook 812, regarding the structure of the second buckle 82, in one embodiment, see Fig.24 and Fig.25 The second buckle 82 includes a buckle opening 821 , the first connecting arm 811 passes through the buckle opening 821 , and the first hook 812 abuts against the structural member 9 on which the second buckle 82 is provided.

[0156] As described above, the structural member 9 provided with the first buckle 81 is referred to as the first structural member 91, and the structural member 9 provided with the second buckle 82 is referred to as the second structural member 92. The first structural member 91 is provided with a first connecting arm 811 on the side facing the second structural member 92, and a first hook 812 is provided at the free end of the first connecting arm 811; the second structural member 92 is provided with a buckle opening 821, the first connecting arm 811 passes through the buckle opening 821, and the first hook 812 abuts against the side of the second structural member 92 facing away from the first structural member 91.

[0157] Exemplarily, a first buckle 81 is disposed on the inner side of the battery rear cover 3 of the electronic device 100 , and a second buckle 82 hole is disposed on the mainboard bracket 5 of the electronic device 100 .

[0158] In this embodiment, the visualization opening 10 may be provided on the first structural member 91 ; or, the visualization opening 10 may be provided on the second structural member 92 .

[0159] When the visual opening 10 is provided on the first structural member 91, please refer to Fig.18 When observed through the visualization opening 10, the first structural member 91 is located in front of the line of sight, and the second structural member 92 is located behind the first structural member 91. Therefore, a reference mark 11 is set on the side of the second structural member 92 facing the first structural member 91, so that the reference mark 11 on the second structural member 92 can be observed through the visualization opening 10.

[0160] When the visualization opening 10 is provided on the second structural member 92, see Fig.25 Since the first buckle 81 is a buckle opening 821, the buckle opening 821 can be used as a visual opening 10. When observing through the buckle opening 821, the second structural member 92 is located in front of the line of sight, and the first structural member 91 is located behind the second structural member 92. Therefore, a reference mark 11 is set on the side of the second structural member 92 facing away from the first structural member 91.

[0161] According to the actual situation, it is selected to set the visual opening 10 on the first structural member 91 or the second structural member 92. For example, when it is difficult to set the reference mark 11 on the side of the second structural member 92 facing away from the first structural member 91, it is optional to set the visual opening 10 on the first structural member 91 and mark the reference mark 11 on the side of the second structural member 92 facing the first structural member 91.

[0162] In this embodiment, since the first structural member 91 is a buckle opening 821, when the first structural member 91 and the second structural member 92 are connected through the first buckle 81 and the second buckle 82, the first structural member 91 and the second structural member 92 fit together. Fig.18 Even if a visualization opening 10 is provided on the first structural member 91 and a reference mark 11 is provided on the surface of the second structural member 92 facing the first structural member 91, since the first structural member 91 is in contact with the second structural member 92, the reference mark 11 is relatively close to the visualization opening 10 along the distribution direction of the first structural member 91 and the second structural member 92, and the positional relationship between the reference mark 11 and the first connecting arm 811 can be easily determined through the visualization opening 10.

[0163] The second buckle 82 provided in this embodiment has a simple structure and is convenient for connecting the first buckle 81 to the second buckle 82 .

[0164] In one embodiment, the second buckle 82 only matches the first buckle 81; in one embodiment, see Fig.26 The buckle structure 8 includes a third buckle 83 , and the third buckle 83 and the first buckle 81 are arranged on the same structural member 9 , that is, the second buckle 82 cooperates with the first buckle 81 and the third buckle 83 .

[0165] In this embodiment, by arranging the third buckle 83 and the first buckle 81 to cooperate with the second buckle 82 , the first structural member 91 and the second structural member 92 are stably connected via the buckle structure 8 .

[0166] Preferably, see Fig.26 The third buckle 83 has the same structure as the first buckle 81. The third buckle 83 includes a third connecting arm and a third hook. The third connecting arm is connected to the first structural member 91. The third hook is arranged at the free end of the third connecting arm. The third hook of the third buckle 83 is arranged opposite to the first hook 812 of the first buckle 81. The third connecting arm passes through the buckle opening 821 and the third hook abuts against the side of the second structural member 92 away from the first structural member 91.

[0167] In this embodiment, the first buckle 81 and the third buckle 83 each correspond to a reference mark 11. The reference mark 11 that cooperates with the first buckle 81 is called the first reference mark, and the reference mark 11 that cooperates with the third buckle 83 is called the second reference mark. When the third buckle 83 and the second buckle 82 are assembled in place, the second reference mark is aligned with the third buckle 83. That is, when the third buckle 83 is installed on the second buckle 82, it can be observed through the visual opening 10 whether the second reference mark 11 is aligned with the third buckle 83 to determine whether the third buckle 83 is installed in place.

[0168] The third connecting arm includes a first side wall and a second side wall that are arranged opposite to each other. A third hook is arranged on the first side wall. When the third hook 83 and the second hook 82 are assembled in place, the second reference mark is aligned with the first side wall, or the second reference mark is aligned with the second side wall, or both the first side wall and the second side wall are aligned with the second reference mark.

[0169] Regarding the first reference mark and the second reference mark, in one embodiment, the shapes of the two are the same, and in another embodiment, the shapes of the two are different.

[0170] Based on the example that the buckle structure 8 includes the third buckle 83, in one embodiment, only the first buckle 81 corresponds to the reference mark 11, while the third buckle 83 does not correspond to the reference mark 11. Exemplarily, the first buckle 81 can be observed through the visualization opening 10, but the third buckle 83 cannot be seen. When the first buckle 81 and the third buckle 83 are connected to the second buckle 82, when the first buckle 81 is aligned with the reference mark 11, it is determined that the third buckle 83 is also assembled with the second buckle 82.

[0171] Regarding the second buckle 82, based on the embodiment in which the second buckle 82 includes a buckle opening 821, in one embodiment, the second buckle 82 also includes a hook protrusion abutting against the first hook 812, and the hook protrusion is arranged on the side of the second structural member 92 away from the first structural member 91. When the first buckle 81 and the second buckle 82 are snapped into place, the first hook 812 abuts against the hook protrusion.

[0172] In this embodiment, by configuring the second buckle 82 to further include a hook protrusion, the first buckle 81 is facilitated to further tightly fit on the second buckle 82 .

[0173] In one embodiment, the second buckle 82 includes two hook protrusions, and the two hook protrusions respectively cooperate with the first hook 812 of the first buckle 81 and the third hook of the third buckle 83 .

[0174] The above describes an embodiment of the buckle structure 8, that is, the second buckle 82 includes a buckle opening 821. Regarding the buckle structure 8, in another embodiment, please refer to Fig. 20 The second buckle 82 includes a second connecting arm 822 and a second hook 823 , the second hook 823 is connected to the second connecting arm 822 , and the other end of the second connecting arm 822 is connected to the corresponding structural member 9 .

[0175] When the first buckle 81 is connected to the second buckle 82, the first hook 812 of the first buckle 81 contacts the second hook 823 of the second buckle 82. When the distance between the structural member 9 (first structural member 91) provided with the first buckle 81 and the structural member 9 (second structural member 92) provided with the second buckle 82 is relatively far, the structure of the second buckle 82 in this embodiment can be adopted to reduce the length of the first connecting arm 811 in the first buckle 81 and improve the strength of the first buckle 81.

[0176] Exemplarily, the structural member 9 provided with the first buckle 81 is the middle frame 2 , and the structural member 9 provided with the second buckle 82 is the mainboard bracket 5 .

[0177] In this embodiment, a visualization opening 10 is preferably provided on the second structural member 92 .

[0178] See also Fig. 20 When the visualization opening 10 is provided on the second structural member 92, when observed through the visualization opening 10, the second structural member 92 is located in front of the sight line, and the first structural member 91 is located behind the second structural member 92, so the reference mark 11 is provided on the side of the second structural member 92 facing away from the first structural member 91. At this time, the distance between the first connecting arm 811 and the reference mark 11 is minimized along the distribution direction of the first structural member 91 and the second structural member 92, so that the positional relationship between the reference mark 11 and the first connecting arm 811 can be easily determined through the visualization opening. Therefore, it is preferred to set the length of the first connecting arm 811 to be greater than the length of the second connecting arm 822, so that the end of the first connecting arm 811 away from the first structural member 91 is close to the second structural member 92. Exemplarily, there is a gap between one end of the first connecting arm 811 away from the first structural member 91 and the side of the second structural member 92 facing the first structural member 91, or, one end of the first connecting arm 811 away from the first structural member 91 is inserted into the visible opening 10 on the second structural member 92, but does not protrude from the side of the second structural member 92 away from the first structural member 91.

[0179] In this embodiment, if a visualization opening 10 is provided on the first structural member 91, when observing through the visualization opening 10, the first structural member 91 is located in front of the sight, the second structural member 92 is located behind the first structural member 91, and a reference mark 11 is provided on the side of the second structural member 92 facing the first structural member 91. Since the distance between the visualization opening 10 and the reference mark 11 is at least greater than the length of the first connecting arm 811, it is difficult to determine the positional relationship between the reference mark 11 and the first connecting arm 811 through the visualization opening 10. Therefore, in the embodiment where the second buckle 82 includes the second connecting arm 822 and the second hook 823, it is preferred to provide a visualization opening 10 on the second structural member 92.

[0180] Regarding the structural member 9 connected by the snap-fit ​​structure 8 in the electronic device 100, in one embodiment, the structural member 9 of the electronic device 100 includes a mainboard bracket 5, a battery back cover 3 and a front shell member, and the battery back cover 3 and the front shell member are located on both sides of the mainboard bracket 5.

[0181] The electronic device 100 generally includes a display screen 1 and a housing, and the battery rear cover 3 and the front housing member form the housing of the electronic device 100. In the cavity surrounded by the display screen 1 and the housing, a mainboard 4, a mainboard bracket 5, and a battery of the electronic device 100 are arranged. The mainboard bracket 5 is located between the battery rear cover 3 and the front housing member, and the mainboard 4 is arranged on the mainboard bracket 5, and the mainboard 4 is located on the side of the mainboard bracket 5 away from the battery rear cover 3.

[0182] In one embodiment, a snap-fit ​​structure 8 is provided between the battery rear cover 3 and the mainboard bracket 5 , and / or a snap-fit ​​structure 8 is provided between the front housing member and the mainboard bracket 5 .

[0183] In this embodiment, when the mainboard bracket 5 is fixed on the battery back cover 3, a buckle structure 8 can be used, that is, one of the mainboard bracket 5 and the battery back cover 3 is provided with a first buckle 81, and the other is provided with a second buckle 82.

[0184] In this embodiment, when the mainboard bracket 5 is fixed to the front housing member, a buckle structure 8 can be used, that is, a first buckle 81 is set on one of the mainboard bracket 5 and the front housing member, and a second buckle 82 is set on the other of the two.

[0185] In this embodiment, it is preferred that the fixing of the mainboard bracket 5 to the battery rear cover 3 and the fixing of the mainboard bracket 5 to the front housing member both adopt the buckle structure 8 of this embodiment, so that the mainboard bracket 5 and the battery rear cover 3 are connected in place, and the mainboard bracket 5 and the front housing member are connected in place.
