Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with aspects of the utility model as detailed in the accompanying claims.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in fig. 1 are merely for convenience in describing the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

Unless defined otherwise, all technical terms used in the embodiments of the present utility model have the same meaning as commonly understood by one of ordinary skill in the art.

The deformation material used in the related art needs to cover the entire axial space of the rotating shaft structure, and thus has a large longitudinal length. In the folding process of the electronic equipment, as the deformation material does not have the ductility in the transverse direction (perpendicular to the axis of the rotating shaft structure), the deformation material needs to move in the transverse direction so as to compensate the screen accommodating space. However, since the deformed material has a large longitudinal length, when the lateral movement occurs, the movement of the sheet in different areas in the longitudinal direction cannot be completely synchronized, and thus the sheet is deformed due to pulling, and as the deformation amount increases, the deformation elasticity of the deformed material itself increases. When the deformation is increased to a certain extent, after the deformation material breaks through the critical state, the deformation material is suddenly flattened under the action of deformation elasticity, and therefore intense vibration and ringing occur.

Therefore, the utility model provides the support component which is suitable for being arranged at the bottom of the screen and compensating the flatness of the support structure at the bottom of the screen, and the first slit can release the deformation stress of the deformation piece, so that the deformation amount of the deformation piece in each small section tends to be the same, and the problems of vibration and abnormal sound caused by inconsistent deformation in the folding process of the deformation piece along with the screen are solved.

The utility model provides an electronic device. In particular, the electronic device may be any of various types of computer system devices (only one form of which is shown by way of example in fig. 1) that are mobile or portable and that perform wireless communications.

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

In one aspect, as shown in connection with fig. 1-4, the present embodiment provides a support assembly 10, the support assembly 10 comprising: a first support 1 and a deformation member 2.

The deformation member 2 is connected with the first support 1 along a first side 201 of the first direction a, and at least one first slit 21 is formed in a second side 202 of the deformation member 2 along the first direction a; the at least one first slit 21 extends at least in the first direction a, and the length of the at least one first slit 21 is smaller than the length of the deformation 2 in the first direction a.

The support component 10 of this embodiment is applicable to and arranges in the screen bottom, compensates screen bottom bearing structure's roughness, and deformation piece 2's first side 201 is connected with first support piece 1, and second side 202 is the free state, and second side 202 is equipped with at least one first slit 21, and first slit 21 is divided into a plurality of minor segments with second side 202, and first slit 21 can release deformation stress of deformation piece 2 for deformation piece 2's in every minor segment deflection tends to the same, thereby is favorable to alleviating deformation piece 2 along with the vibration and the abnormal sound problem that the screen folding in-process produced because of deformation inconsistency.

The length of the first slit 21 is smaller than the length of the deformable member 2 in the first direction a, so that the deformable member 2 is not completely broken, in particular the first side 201 of the deformable member 2, still has a complete shape. When the first side 201 of the deformation member 2 is connected with the first support member 1, the deformation member 2, and thus the deformation member 2 between the whole deformation member 2 and the first slit 21, is kept as a whole, so that the whole deformation member 2 can be ensured to move laterally with the first side 201 as a reference in the bending process.

In some possible implementations, the deformation 2 is any one of the following: stainless steel sheet, rigid plastic sheet, toughened glass sheet, etc. have certain flexibility, but local rigidity is great, can guarantee to compensate the roughness of screen bottom, still can not influence the normal folding performance of screen.

In some possible implementations, the first direction a is the direction in which the dimension of the deformation 2 spans less. For example, if the deformable member 2 is a rectangular member, the first direction a is the direction in which the short side or width of the deformable member 2 is located. For another example, if the deformable member 2 is an elliptical member, the first direction a is the direction in which the minor axis of the deformable member 2 is located. It should be noted that the shape of the deformable member 2 is not limited to the above example, and the shape of the deformable member may be adjusted according to actual needs.

Therefore, the first slit 21 can divide the larger span size of the deformed part 2 into at least two sections, so that the severity of deformation error accumulation in the transverse movement process of the deformed part 2 is reduced, and the problem that vibration or abnormal sound occurs when the deformation error accumulation exceeds the limit due to the larger span is avoided.

In other possible implementations, the at least one first slit 21 extends at least along the first direction a, which may be understood as the first slit 21 extending along the first direction a, and may be understood as the first slit 21 diffracting along the first direction a and extending towards the other direction. For example, the first slit 21 extends in both the first direction a and the second direction b, i.e. the first slit 21 is at an angle to the first direction a.

It should be noted that the number and the positions of the first slits 21 in the deformation member 2 can be reasonably selected and arranged according to actual requirements, which is not limited by the present utility model.

As shown in connection with fig. 1, 2, in some embodiments, the number of first slots 21 is at least two, the at least two first slots 21 being spaced apart along the second direction b and arranged side by side on the second side 202; the second direction b and the first direction a form a preset included angle.

When the number of the first slits 21 is at least two, the at least two first slits 21 are arranged side by side at intervals along the second direction b, so that the second side 202 of the deformation member 2 is broken into a plurality of cells along the second direction b, the accumulated deformation error which can be generated between each cell is smaller, the material limit is not reached, and the problem of vibration or abnormal sound is not caused.

The first direction a and the second direction b of the embodiment form a preset included angle, so that the purpose of breaking the deformation member 2 along the second direction b by using the first slit 21 can be achieved.

In some possible implementations, the preset angle of the first direction a and the second direction b is greater than zero and less than or equal to 90 °, including, but not limited to, 5 °, 10 °, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 70 °, 80 °, 90 °, and so on. Further, the preset angle of the first direction a and the second direction b is 90 °.

Referring to fig. 5, in some embodiments, at least one first slit 21 has a length L1 along the first direction a, the deformable member 2 has a length L2 along the first direction a, and the value of L1/L2 ranges from 0.4 to 0.8. The length of the first slit 21 in the first direction a is understood to be the length of the projection of the first slit 21 in the first direction a.

When the length L1 of the first slit 21 along the first direction a and the length L2 of the deformed member 2 along the first direction a satisfy the above-mentioned ratio range, it is possible to achieve that the deformed member 2 eliminates vibration and abnormal sound by means of the first slit 21 while ensuring that the deformed member 2 has good overall translational characteristics and good flatness, and the deformed member 2 can better support and protect the bottom of the screen without affecting the bending characteristics of the screen.

In some possible implementations, the ratio L1/L2 of the length L1 of the first slit 21 along the first direction a to the length L2 of the deformable member 2 along the first direction a is, for example, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, etc.

Optionally, the ratio L1/L2 of the length L1 of the first slit 21 along the first direction a to the length L2 of the deformable member 2 along the first direction a is 0.5.

As shown in connection with fig. 2, 6 and 7, in some embodiments, the first side 201 of the deformation 2 extends to the surface of the first support 1; the support assembly 10 further comprises a connection layer 3, the connection layer 3 being located between the deformation 2 and the first support 1, and the connection layer 3 being arranged along the first side 201 of the deformation 2.

The first side 201 of the deformation member 2 extends to the surface of the first support member 1, and the surface of the first support member 1 is flatly connected with the surface of the adjacent other support structures, so that the bottom of the screen is flatly supported. Since the deformable member 2 needs to be moved laterally during folding of the screen, lateral compensation of the bending region 2001 is achieved. The first support piece 1 is located one side of the deformation piece 2, which faces away from the screen, and the first support piece 1 realizes bending compensation through the lateral movement of the first support piece 1 in the folding process of the screen. Therefore, the first side 201 of the deformation member 2 is fixedly connected with the first support member 1 through the connecting layer 3, and other parts except the first side 201 of the deformation member 2 are in a free state relative to the first support member 1, so that when the first support member 1 moves transversely, the first side 201 of the deformation member 2 can be pulled through the connecting layer 3, and the whole deformation member 2 moves transversely. Meanwhile, due to the bending action and the non-scalability of the deformation member 2, the deformation member 2 and the first support member 1 are located on different bending radii, a certain interlayer displacement occurs between the deformation member 2 and the first support member 1, and the deformation member 2 is in a free state except for the first side 201, so that the deformation member 2 will perform the interlayer displacement based on the first side 201 without generating additional internal and external stresses.

As shown in connection with fig. 7, in some embodiments, the length L3 of the connecting layer 3 extending in the first direction a is 5% -20% of the length L2 of the deformation 2 in the first direction a.

In order to achieve a reliable connection of the deformation element 2 and the first support element 1, the length L3 of the connection layer 3 extending in the first direction a needs to be 5% to 20% of the total length of the deformation element 2.

In some possible implementations, the length L3 of the connecting layer 3 extending along the first direction a is a percentage, e.g., 5%, 6%, 7%, 8%, 9%, 10%, 12%, 15%, 17%, 20%, etc., of the length L2 of the deformable member 2 along the first direction a. Alternatively, the length L3 of the connecting layer 3 extending in the first direction a accounts for 8% of the length L2 of the deformation 2 in the first direction a.

In other possible implementations, the connection layer 3 may include, but is not limited to: back glue, adhesive, and the like.

As shown in connection with fig. 2, 3, 6 and 7, in some embodiments the support assembly 10 further comprises a cushioning layer 4, the cushioning layer 4 being located on the surface of the deformation member 2 facing the first support member 1. By arranging the buffer layer 4 on the surface of the deformation member 2 facing the first support member 1, the vibration absorbing effect can be achieved, and vibration and friction between the deformation member 2 and the first support member 1 can be further reduced.

In some possible implementations, the buffer layer 4 may include, but is not limited to: foam, rubber pads, and the like.

Optionally, the buffer layer 4 is adhesively connected with the surface of the deformation member 2 facing the first support member 1, so that when the deformation member 2 moves or deforms transversely, the buffer layer 4 can move synchronously with the deformation member 2 to perform continuous buffer protection on the surface of the deformation member 2.

As shown in connection with fig. 2, 4, in some embodiments, the cushioning layer 4 is provided with second slits 41, the second slits 41 being arranged in correspondence with the at least one first slit 21. By arranging the second slits 41 arranged corresponding to the first slits 21 on the buffer layer 4, the problem that the deformation accumulation of the buffer layer 4 itself drives the deformation member 2 to vibrate or produce abnormal sound can be avoided.

Illustratively, the second slots 41 are the same as the first slots 21 in number and correspond in position. It is understood that the second slits 41 coincide with the orthographic projections of the first slits 21 in the lamination direction of the cushion layer 4 and the deformable member 2 one by one.

As shown in connection with fig. 1-4, in some embodiments, the support assembly 10 further comprises a second support 5 and a spindle structure 6; the first support member 1 and the second support member 5 are respectively located at two sides of the rotating shaft structure 6 along the first direction a, and the second side 202 of the deformation member 2 corresponds to the second support member 5.

The extension length of the deformation member 2 along the second direction b is the same as the extension length of at least one of the rotation shaft structure 6, the first support member 1 and the second support member 5 along the second direction b.

The supporting component 10 forms a stable and foldable supporting reference by using the first supporting element 1, the rotating shaft structure 6 and the second supporting element 5 at the bottom, but due to the fact that enough translational movement gaps are reserved when the three components are connected in a matched mode, the joint positions among the three components and the hole groove structures on the three components cause the flatness of the supporting surface facing the bottom of the screen to be insufficient. The first side 201 of the deformation member 2 of the present embodiment is located on the first support member 1, and the second side 202 is located on the second support member 5, so that uneven areas such as the joint gaps of the first support member 1, the rotating shaft structure 6 and the second support member 5 can be covered, thereby effectively improving the flatness of the support assembly 10.

As shown in connection with fig. 1-4 and 7, in some embodiments, the second side 202 of the deformation 2 extends to the surface of the second support 5; the support assembly 10 includes a cushioning layer 4; the buffer layer 4 is located at least between the deformation element 2 and the second support 5. The buffer layer 4 of this embodiment is located between the deformation member 2 and the second support member 5, and can play a role in buffering and absorbing vibration, and reduce vibration and friction between the deformation member 2 and the second support member 5.

As shown in connection with fig. 1-4, in some embodiments, the support assembly 10 further includes a third support 7 and a fourth support 8, the third support 7 and the fourth support 8 being respectively connected to the shaft structure 6, the third support 7 and the fourth support 8 being capable of being rotatably unfolded under the constraint of the shaft structure 6 to the state shown in fig. 1 and rotatably folded to the state shown in fig. 3. The third support 7 and the fourth support 8 are used for supporting the screen together with the first support 1, the second support 5 and the rotating shaft structure 6. The third support 7 and the fourth support 8 may also be used for providing support and fixation for electronic devices such as batteries, motherboards, etc. of electronic devices, for example.
