This results in the gap between the snap-fit ​​parts of the front frame and the back panel being actually assembled, which can reach 0.3mm at the extreme. This gap value will cause abnormal noises when the snap-fit ​​parts collide with each other. Summary of the invention

In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0034] The electronic device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] The electronic device 100 according to the embodiment of the present invention is as follows: Figure 1 As shown, it includes: a main frame 1, a display screen 2, a back panel 3 and a front frame 4.

[0036] The main frame 1 is the structural framework of the electronic device 100, and the main frame 1 has a front, a back and a side, and the side of the main frame 1 is connected between the front and back of the main frame 1. The display screen 2 is arranged on the main frame 1, and the display surface of the display screen 2 is consistent with the front direction of the main frame 1.

[0037] The back plate 3 is connected to the back of the main frame 1, and the edge of the back plate 3 is provided with a back plate first buckle portion 301. The front frame 4 includes an annular front trim plate 41 and a side trim plate 42 connected to the outer edge of the front trim plate 41, the front trim plate 41 is connected to the front of the main frame 1 and covers the edge of the display screen 2, the side trim plate 42 is located on the side of the main frame 1, and the side trim plate 42 is provided with a side first buckle portion 401 that matches the back plate first buckle portion 301.

[0038] On the electronic device 100 with the display screen 2, after the display screen 2 is installed on the main frame 1, the back plate 3 seals the back of the main frame 1 to protect the display screen 2 and other components on the main frame 1. After the front frame 4 is buckled on the front of the main frame 1, the annular front decorative plate 41 can just cover the edge of the display screen 2. On the one hand, it blocks the edge of the display screen 2 to improve the aesthetics, and on the other hand, it cooperates with the main frame to limit the display screen 2. The side decorative plate 42 located on the side of the main frame 1 is snap-connected with the back plate 3. The snap-connection form makes the assembly efficiency of the electronic device 100 higher and is convenient for disassembly, maintenance, and repair. After the side decorative plate 42 is snap-connected with the back plate 3, the main frame 1 and the display screen 2 are clamped between the back plate 3 and the front frame 4, so that the electronic device 100 forms a whole in appearance.

[0039] It is understandable that, since the first buckle portion 301 of the back plate and the first buckle portion 401 of the side portion need to be buckled together, an assembly gap f needs to be pre-designed between the two in the structural design. Figure 1Taking the structure shown as an example, when assembling the front frame 4, the front frame 4 is pressed toward the back panel 3. When the front decorative plate 41 is close to the front of the main frame 1 and the back panel 3 is close to the back of the main frame 1, the first side buckle part 401 is buckled on the first back panel buckle part 301. Due to the existence of the assembly gap f, the first side buckle part 401 has no interference during the buckling process and the buckling action can be completed smoothly. When there is no error in the processing of the first back panel buckle part 301 and the first side buckle part 401, the maximum gap between the first back panel buckle part 301 and the first side buckle part 401 after the electronic device 100 is assembled is equal to the assembly gap f. However, in fact, when the back panel 3 and the front frame 4 are processed, it can only be guaranteed that the position accuracy of the first back panel buckle part 301 and the first side buckle part 401 is within a certain tolerance range. For example, the assembly gap f is 0.1mm, and the processing position design value of the first back panel buckle part 301 on the back panel 3 (such as Figure 2 The tolerance of s1 is ±0.1 mm, and the processing position design value of the first buckle portion 401 on the upper side of the front frame 4 (such as Figure 2 The tolerance of s2) is ±0.1mm. When the positions of the first back plate buckle part 301 and the first side buckle part 401 reach the limit deviation, the actual gap between the first back plate buckle part 301 and the first side buckle part 401 will reach 0.3mm (i.e. 0.1mm+0.1mm+0.1mm). This 0.3mm gap value will cause the two buckles to be in relative position when shaking, resulting in collision noise.

[0040] The solution of this application is to solve the above problems. Figure 1 As shown, a first sinking groove 101 is provided on the front of the main frame 1, and the electronic device 100 further includes a first elastic sheet 51 located in the first sinking groove 101, and a thickness p1 of the first elastic sheet 51 is greater than a depth v1 of the first sinking groove 101. Here, the direction from the front of the main frame 1 to the back of the main frame 1 is taken as the front-to-back direction, that is, the front-to-back dimension of the first elastic sheet 51 is greater than the front-to-back dimension of the first sinking groove 101.

[0041] The first elastic sheet 51 is elastic, so when the front frame 4 is pressed toward the back plate 3 during assembly, the first elastic sheet 51 can be compressed. Figure 1 The middle compression amount y1=p1-v1. In this way, the front trim panel 41 can be as close to the front of the main frame 1 as possible, and a gap is formed between the first snap-in portion 301 of the back panel and the first snap-in portion 401 of the side, so as to facilitate the buckling of the first snap-in portion 301 of the back panel and the first snap-in portion 401 of the side. After the assembly is completed and there is no external force, when the first elastic sheet 51 returns to its original shape, it will press the front trim panel 41 away from the front of the main frame 1, thereby reducing the gap between the first snap-in portion 301 of the back panel and the first snap-in portion 401 of the side, and even the first snap-in portion 301 of the back panel and the first snap-in portion 401 of the side are tightly attached without a gap, thereby reducing abnormal noise. Figure 3In the example shown, when pressed, the thickness of the first elastic sheet 51 is compressed to v1, and a gap y1=p1-v1 is formed between the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side plate; after the first elastic sheet 51 recovers, the thickness of the first elastic sheet 51 recovers to p1, and a gap y2=0 is formed between the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side plate.

[0042] Here, the front of the main frame 1 is only partially provided with the first recessed groove 101, and the first elastic sheet 51 is installed in the first recessed groove 101, so that the first elastic sheet 51 can be contracted in the first recessed groove 101 when compressed. The provision of the first recessed groove 101 also facilitates the rapid assembly of the first elastic sheet 51.

[0043] According to the electronic device 100 of the embodiment of the present invention, a first recess 101 is provided on the front of the main frame 1 to install the first elastic sheet 51, and the thickness p1 of the first elastic sheet 51 is greater than the depth v1 of the first recess 101. During assembly, the first elastic sheet 51 can be compressed so that a gap can exist between the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side so that they can be interlocked. After assembly, the first elastic sheet 51 can be restored to reduce the gap between the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side, or even eliminate the gap between the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side, thereby solving the problem of abnormal noise caused by the collision of the snap-in portions.

[0044] exist Figure 1 In the illustrated embodiment, when there is no error in the processing of the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side, if the assembly gap is 0.1mm. At this time, the thickness p1 of the first elastic sheet 51 can be set to be 0.1mm greater than the depth v1 of the first sink 101, that is, when the size of the snap-in portions on the front frame 4 and the back plate 3 is the design median (no processing size error), the assembly gap is 0.1mm, then after actual assembly, the first elastic sheet 51 can prop up the front trim 41 of the front frame 4, and a 0.1mm gap is generated between the main frame 1 and the front trim 41 of the front frame 4, while the gap between the first snap-in portion 301 of the back plate and the first snap-in portion 401 of the side is 0, and the two are always in contact, thereby effectively improving the thickness direction (such as Figure 1 Abnormal noise caused by assembly due to vibration impact in the front and rear directions (as shown).

[0045] In the actual mass production process, the position dimensions of the first snap-in portion 301 of the back panel and the first snap-in portion 401 of the side fluctuate within a tolerance range of ±0.1mm. When the positions of the two snap-in portions are offset in a certain direction, plus the designed assembly gap of 0.1mm, the final gap reaches a limit deviation of 0.3mm. At this time, the thickness p1 of the first elastic sheet 51 is set to be 0.3mm larger than the depth v1 of the first groove 101 to completely offset the gap value between the two snap-in portions.

[0046] However, in actual applications, it is difficult to set the thickness p1 of the first elastic sheet 51 to be 0.3 mm greater than the depth v1 of the first recess 101. This is because, on the one hand, when the thickness p1 of the first elastic sheet 51 is 0.3 mm greater than the depth v1 of the first recess 101, it will cause difficulty in assembling the front frame 4, so the compression of the first elastic sheet 51 increases, and the external force required for assembly pressing increases, especially when the positions of the two buckle parts are offset in a certain opposite direction, the required pressing external force is greater. On the other hand, due to the development of modern process technology, generally when processing the back plate 3 and the front frame 4, most (up to 98%) of the positions of the back plate first buckle part 301 and the side first buckle part 401 will not reach the above-mentioned limit deviation position, and after the buffering of the first elastic sheet 51, even if a certain gap is left between the back plate first buckle part 301 and the side first buckle part 401, no obvious abnormal sound will be generated.

[0047] Considering many factors such as assembly and actual processing errors, preferably, the thickness p1 of the first elastic sheet 51 is selected to exceed the depth v1 of the first sink groove 101 by 0.1-0.2 mm. This can reduce the difficulty of assembly and eliminate obvious abnormal noise. For example, the thickness p1 of the first elastic sheet 51 is selected to exceed the depth v1 of the first sink groove 101 by 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, etc.

[0048] Of course, the solution of the present application does not exclude that in some embodiments, the first elastic sheet 51 and the front frame 4 are in an interference fit. That is to say, when there is no gap between the first buckle portion 301 of the back plate and the first buckle portion 401 of the side portion, the first elastic sheet 51 is still in a compressed state, so that the first elastic sheet 51 applies a spring pressure to the front frame 4 in a direction away from the front of the main frame 1. In this way, a compressed state is formed between the first buckle portion 301 of the back plate and the first buckle portion 401 of the side portion, and even between the back plate 3 and the main frame 1, and between the main frame 1 and the front frame 4, which makes it less likely to produce collision noise.

[0049] In the solution of the present application, there is no specific restriction on the material of the first elastic sheet 51, which may be a rubber sheet or a silicone sheet, etc. Optionally, the first elastic sheet 51 is a silicone sheet, which has excellent high temperature resistance and low temperature resistance, and has the characteristics of weather resistance, water repellency, electrical insulation, physiological inertness, etc., and is non-toxic and safe.

[0050] Optionally, the first elastic sheet 51 is attached to the first sink groove 101, for example, the first elastic sheet 51 is glued to the main frame 1 by adhesive. In this way, before assembling the front frame 4, the first elastic sheet 51 can be fixed to the main frame 1 to avoid displacement of the first elastic sheet 51 during assembly. In some solutions, the first elastic sheet 51 can be stuck in the first sink groove 101, for example, the notch of the first sink groove 101 is used as a shrinkage, and after the first elastic sheet 51 is installed in the first sink groove 101, it is not easy to shift even without adhesive.

[0051] Further optionally, the first elastic sheet 51 is rectangular, which is simple in shape and easy to process. Of course, the present application does not exclude the first elastic sheet 51 from being formed into other shapes, such as a circle or a diamond.

[0052] In some embodiments, the main frame 1 is square-shaped, and the border width of the main frame 1 is greater than or equal to 2.5 mm, that is, the width of the main frame 1 at the outer portion of the display screen 2 is at least 2.5 mm. Such a main frame 1 is provided with a first groove 101 and a first elastic sheet 51 is installed, which can provide an effective support width.

[0053] In some embodiments, Figure 4 and Figure 5 As shown, the inner periphery of the main frame 1 is provided with a plurality of positioning blocks 102, and the plurality of positioning blocks 102 are arranged around the display screen 2 to position the display screen 2, and a first sink 101 and a corresponding first elastic sheet 51 are formed on at least one positioning block 102. It can be understood that the frame width w1 of the main frame 1 at the positioning block 102 is larger than the frame width w2 at other positions, for example, the frame width w2 here is at least 0.4 mm larger than that at other positions. The first sink 101 and the corresponding first elastic sheet 51 are arranged here, and the first elastic sheet 51 can be arranged wider, which is conducive to giving full play to the supporting capacity of the first elastic sheet 51.

[0054] Specifically, the display screen 2 is rectangular, and at least two positioning blocks 102 are provided on each side of the main frame 1 corresponding to the display screen 2. Two positioning blocks 102 are provided on each side adjacent to the display screen 2 at both ends of the side, and each positioning block 102 is provided with a first sink 101 and a corresponding first elastic sheet 51. In this way, the four sides of the corresponding display screen 2 are supported by the first elastic sheet 51, and the front frame 4 is propped up at all sides of the entire circumference, so that the front frame 4 cannot shake relative to the main frame 1 at any place, thereby better solving the problem of abnormal noise.

[0055] Optionally, the main frame 1 is a rectangular frame, and the two positioning blocks 102 on each side are respectively about 20 mm away from the two end points of the main frame 1 on the side. That is, the positioning blocks 102 are located at the four sides of the main frame 1, about 20 mm away from the four corners, and are distributed more evenly. In this case, each positioning block 102 is provided with a first elastic sheet 51, and the elastic support of the first elastic sheet 51 on the front frame 4 is also more uniform.

[0056] In some solutions, two positioning blocks 102 are respectively provided on the corresponding four sides of the main frame 1, and the buckle parts (including the first buckle part 301 of the back plate and the second buckle part 302 of the back plate described below) on the back plate 3 are also provided at both ends of the four sides of the main frame 1. The first elastic sheet 51 is provided on the positioning block 102, so that the layout of the first elastic sheet 51 is similar to the layout position of the buckle part, and the first elastic sheet 51 on each side is close to the buckle part, which can effectively solve the problem of abnormal noise.

[0057] Of course, in addition to the positioning block 102, the first sink 101 and the corresponding first elastic sheet 51 can also be provided at other positions of the main frame 1. The selection of the position of the first sink 101 depends on the frame width of the main frame 1 and the reasonable requirements of the specific structure.

[0058] For example, the main frame 1 is provided with a first sink 101 and a corresponding first elastic sheet 51 at the middle position of at least one long side of the display screen 2. It is understandable that if the first elastic sheets 51 are only provided at both ends of the long side of the display screen 2, the distance is too far, resulting in insufficient support in the middle. Therefore, the first elastic sheet 51 is provided at the middle position of the corresponding long side, which can improve the effective support of the middle position, ensure the uniform distribution effect, and make the front frame 4 at the middle position be propped up without shaking.

[0059] Specifically, Figure 6 As shown, the first sink 101 is closed at one end adjacent to the display screen 2 and is open at one end away from the display screen 2. Since the main frame 1 needs to support the display screen 2, the first sink 101 is closed at one end adjacent to the display screen 2, which is beneficial to improving the support and protection performance of the display screen 2. The other end of the first sink 101 is set to be open, which is convenient for installing the first elastic member 51 into the first sink 101. When the first elastic member 51 is glued to the main frame 1, the outer end is open to allow excess glue to flow out without contaminating the display screen 2.

[0060] In some embodiments, Figure 7 As shown, a second recessed groove 103 is provided on the side of the main frame 1, and the electronic device 100 further includes a second elastic sheet 52 provided in the second recessed groove 103, and a thickness p2 of the second elastic sheet 52 is greater than a depth v2 of the second recessed groove 103. Here, the thickness p2 of the second elastic sheet 52 and the depth v2 of the second recessed groove 103 refer to the dimensions of the second elastic sheet 52 and the second recessed groove 103 in the direction from the side thereof to the display screen 2. For example, when the second recessed groove 103 is provided on the left side of the main frame 1, the depth v2 of the second recessed groove 103 refers to the dimension of the second recessed groove 103 in the left-right direction.

[0061] The second elastic sheet 52 is elastic, so when the front frame 4 is pressed toward the back plate 3 during assembly, the second elastic sheet 52 can be compressed, so that the side trim 42 can cover the outside of the main frame 1. After the assembly is completed and there is no external force, when the second elastic sheet 52 returns to its original shape, it will press the side trim 42 away from the side of the main frame 1. In this way, after the side trim 42 is propped up, it is not easy for the side trim 42 to collide with the side of the main frame 1 to produce abnormal noise.

[0062] Here, the side of the main frame 1 is only partially provided with the second recessed groove 103, and the second elastic sheet 52 is installed in the second recessed groove 103, so that the second elastic sheet 52 can be contracted in the second recessed groove 103 when compressed. The second recessed groove 103 is also provided to facilitate the rapid assembly of the second elastic sheet 52.

[0063] In the solution of the present application, there is no specific restriction on the material of the second elastic sheet 52, which may be a rubber sheet or a silicone sheet, etc. Optionally, the second elastic sheet 52 is a silicone sheet, which has excellent high temperature resistance and low temperature resistance, and has the characteristics of weather resistance, water repellency, electrical insulation, physiological inertness, etc., and is non-toxic and safe.

[0064] Optionally, the second elastic sheet 52 is attached to the second sink groove 103, for example, the second elastic sheet 52 is glued to the main frame 1 by adhesive. In this way, before assembling the front frame 4, the second elastic sheet 52 can be fixed to the main frame 1 to avoid the second elastic sheet 52 from shifting during assembly. In some solutions, the second elastic sheet 52 can be stuck in the second sink groove 103, for example, the notch of the second sink groove 103 is used as a shrinkage, and after the second elastic sheet 52 is installed in the second sink groove 103, it is not easy to shift even without adhesive.

[0065] Further optionally, the second elastic piece 52 is rectangular, which is simple in shape and easy to process. Of course, the present application does not exclude the second elastic piece 52 from being formed into other shapes, such as a circle or a diamond.

[0066] Specifically, Figure 7 As shown, the second sink 103 is open at one end adjacent to the front of the main frame 1 and closed at one end adjacent to the back of the main frame 1. In this way, the second elastic sheet 52 can be conveniently installed at the open end, and the second elastic sheet 52 can be covered and shielded by the front frame 3 after being installed here, without affecting the appearance.

[0067] Specifically, Figure 7 and Figure 8 As shown, at least one second sink 103 is connected to the first sink 101, and the corresponding second elastic sheet 52 is connected to the first elastic sheet 51. The connected second elastic sheet 52 and first elastic sheet 51 are L-shaped as a whole, which has higher assembly efficiency and reduces assembly steps.

[0068] Optionally, all the first elastic sheets 51 are connected to the second elastic sheets 52 , so that the second elastic sheets 52 are similarly distributed to the first elastic sheets 51 , and can support the front frame 4 all around.

[0069] Furthermore, the second elastic sheet 52 is connected to the first elastic sheet 51 by chamfering at the connection. Optionally, the connection between the second elastic sheet 52 and the first elastic sheet 51 can be rounded or chamfered. The setting of the chamfer provides a space for the deformation when the first elastic sheet 51 and the second elastic sheet 52 are slightly deformed due to interference extrusion. In addition, after the connection between the two elastic sheets is chamfered, the front frame is less obstructed when it is covered on the main frame 1, which can facilitate the easy snap-on assembly of the front frame 4.

[0070] Optionally, the second elastic sheet 52 and the first elastic sheet 51 are an integrally formed silicone sheet, so that during processing, the second elastic sheet 52 and the first elastic sheet 51 can be made into a straight strip as a whole, and during installation, the straight strip is bent to form the first elastic sheet 51 and the second elastic sheet 52, and are placed in two sinks. The silicone sheet has strong toughness and is not easy to break after being bent.

[0071] In some embodiments, Figure 6 As shown, the side of the back plate 3 is also provided with a back plate second buckle part 302, and the main frame 1 is also provided with a side second buckle part 104 that cooperates with the back plate second buckle part 302. Similarly, when the first elastic sheet 51 is not provided between the front frame 4 and the main frame 1, the gap between the back plate second buckle part 302 and the side second buckle part 104 also makes it easy for the two to collide and produce abnormal noise, and after the first elastic sheet 51 is provided, the probability of abnormal noise between the two can be reduced. When the second elastic sheet 52 is provided, the possibility of abnormal noise can be further reduced.
