Detailed Description

Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific illustrations are for the purpose of illustrating how one skilled in the art may practice the application, and are not intended to be exhaustive of all of the possible ways of practicing the application, nor to limit the scope of the application.

In the present application, "axial", "radial", and "circumferential" of a certain component refer to the direction of the component along the central axis, the direction along the radius, and the direction along the circumference, respectively. In the folded state, the central axes of the base body and the spiral cover of the supporting component are on the same straight line, so that the axial direction, the radial direction and the circumferential direction of the base body are respectively the same as the axial direction, the radial direction and the circumferential direction of the spiral cover; in the deployed state, the central axes of both the base body and the screw cap of the support assembly are coplanar and intersect, and the axial direction, the radial direction and the circumferential direction of the base body are different from those of the screw cap.

In the present application, the support surface means a horizontal surface capable of supporting the electronic terminal device, a curved surface having a large radius of curvature, and the like, and typically may be a desktop, for example.

The embodiment of the application provides a support component for electronic terminal equipment, a protective shell component and the electronic terminal equipment. The electronic terminal device may in particular be a portable electronic terminal device, such as a mobile phone, a tablet computer or the like.

As shown in fig. 1A to 1C and 2A to 2D, the support assembly according to an embodiment of the present application includes a base 1, a screw cap 2, and a folding support mechanism 3 assembled together. The folding support mechanism 3 is mounted to the base 1 and the screw cap 2, and the folding support mechanism 3 has a configuration capable of rotating with respect to the base 1 and the screw cap 2, thereby enabling the support assembly to be switched between a folded state (as shown in fig. 1A to 1C) and an unfolded state (as shown in fig. 2A to 2D). As shown in fig. 1A to 1C, when the support assembly is in the folded state, both the base 1 and the screw cap 2 are arranged in parallel so that the support assembly is in a flat plate configuration, thereby enabling the space occupied by the support assembly to be reduced as much as possible so as to be portable. As shown in fig. 2A to 2D, when the support assembly is in the unfolded state, the screw cap 2 is at an angle with respect to the base 1 and is located in a different plane from the base 1, so that the support assembly is in a stand configuration in which the screw cap 2 is arranged at an angle with respect to the base 1, thereby supporting the portable electronic terminal device on a support surface in different postures using an edge of the screw cap 2 and an edge of a housing of the portable electronic terminal device.

In the present embodiment, as shown in fig. 3A to 3E, the base 1 is formed in a disk shape as a whole. The base 1 includes first magnets 11, a base upper cover 12, and a bottom plate 13 assembled together, and a plurality of first magnets 11 are disposed in a space defined by the base upper cover 12 and the bottom plate 13.

As shown in fig. 3C and 3D, seven first magnets 11 are provided, and these first magnets 11 are each a permanent magnet. The plurality of first magnets 11 are distributed at intervals along the circumferential direction of the base body 1, and each of the first magnets 11 is formed in a circular arc shape having a predetermined length. Further, these first magnets 11 are located at the outer peripheral portion of the base 1. With these first magnets 11, the base body 1 of the support assembly can be easily attached to and detached from the housing of the portable electronic terminal device by magnetic attraction.

The support assembly may also be magnetically or otherwise attached to the protective case for the electronic terminal device to form a protective case assembly, among other possibilities. The protective case is detachably mountable to the electronic terminal device by a user. In at least some cases, the protective case as the object to be mounted may include a magnet that attracts the magnet of the support assembly or a ferromagnetic material or member such as iron.

As shown in fig. 3A to 3C, the base upper cover 12 is formed in a disk shape. The surface of the base upper cover 12 facing away from the bottom plate 13 is formed with a base recess 12c, and the first magnet 11 is located radially outside the base recess 12 c. As shown in fig. 1C, in the folded state, the first rotating portion 33 of the folding support mechanism 3 is received in the base recess 12C, and the first magnet 11 and the first rotating portion 33 are arranged to overlap in the axial direction of the base 1 (that is, the first magnet 11 and the first rotating portion 33 are at least partially overlapped as viewed in at least one radial direction of the base 1). In this way, it is advantageous to reduce the axial thickness of the support assembly in the folded condition. Further, the surface of the base upper cover 12 facing the bottom plate 13 is formed with a first mounting projection 12p1 and a second mounting projection 12p2, and the first mounting projection 12p1 and the second mounting projection 12p2 are each projected toward the bottom plate 13. The base upper cover 12 is also formed with a first mounting through hole 12h1 and a second mounting through hole 12h2 penetrating along the axial direction of the base 1. Thereby, as shown in fig. 1C and 2D, the first fixing portion 31a of the folding supporting mechanism 3 can extend between the base upper cover 12 and the bottom plate 13 to be fitted to the first mounting projection 12p1 via the first mounting through hole 12h 1; the second fixing portion 31b of the folding supporting mechanism 3 can extend between the base upper cover 12 and the bottom plate 13 to fit over the second mounting projection 12p2 via the second mounting through hole 12h2, so that the fixing portions (the first fixing portion 31a and the second fixing portion 31 b) of the folding supporting mechanism 3 are fixed with the base 1. Further, the outer peripheral portion of the base upper cover 12 is formed with a cover opening recess 12n recessed toward the bottom plate 13 and opened toward the radial outside, and the cover opening recess 12n facilitates the operator to insert a finger between the base 1 and the spin cover 2 to apply a driving force for rotating the spin cover 2 with respect to the base 1.

As shown in fig. 3B and 3E, the bottom plate 13 is formed in a flat circular plate shape. The bottom plate 13 is fixedly mounted to the base upper cover 12 so as to define the plurality of first magnets 11 and the fixing portions 31a, 31b of the folding support mechanism 3 within a space surrounded by the bottom plate 13 and the base upper cover 12. The bottom plate 13 is also matched to the surface shape of the housing of the portable electronic terminal device, for example, both are planar, so that the base 1 is more stably mounted to the housing of the portable electronic terminal device.

In the present embodiment, as shown in fig. 4A to 4D, the spin cover 2 is integrally formed in a disk shape. The spin cover 2 includes a second magnet 21, a fourth magnet 22, a top cover 23, and a mounting ring 24 assembled together, the second magnet 21 and the fourth magnet 22 being disposed in a space defined by the top cover 23 and the mounting ring 24.

As shown in fig. 4C and 4D, one second magnet 21 and two fourth magnets 22 are provided, and these magnets 21, 22 are each a permanent magnet. The second and fourth magnets 21 and 22 are spaced apart along the circumferential direction of the spin cover 2, and the second and fourth magnets 21 and 22 are formed in a circular arc shape having a predetermined length. Further, a second magnet 21 and fourth magnets 22 are located at the outer peripheral portion of the base 1, the second magnet 21 corresponding to one of the first magnets 11, each of the fourth magnets 22 corresponding to one of the first magnets 11, respectively. As shown in fig. 1C, when the support assembly is in the folded state, the second magnet 21 and the fourth magnet 22 are magnetically engaged with the corresponding first magnet 11, respectively, so that the support assembly can be maintained in the folded state without an external force. As shown in fig. 2D, when the support assembly is in the unfolded state, the second magnet 21 is separated from the first magnet 11 and magnetically engaged with the third magnet 35 of the folding support mechanism 3, so that the support assembly can be maintained in the unfolded state without an external force. At this time, the fourth magnet 22 is separated from both the first magnet 11 and the third magnet 35.

As shown in fig. 4A to 4C, the top cover 23 is formed in a disk shape. The surface of the top cover 23 facing the base body 1 in the folded state is formed with a cap recess 23c, and the second magnet 21 and the fourth magnet 22 are located radially outside the cap recess 23 c. As shown in fig. 1C, in the folded state, both the second rotating portion 34 and the supporting portion 32 of the folding support mechanism 3 are received in the cap recess 23C, and the second magnet 21 and the fourth magnet 22 are arranged to overlap the second rotating portion 34 and the supporting portion 32 in the axial direction (that is, the second magnet 21 and the fourth magnet 22 are arranged to overlap the second rotating portion 34 and the supporting portion 32 at least partially as viewed in at least one radial direction).

As shown in fig. 4B, the mounting ring 24 is formed in a flat circular ring shape. The mounting ring 24 is fixedly mounted to the top cover 23 to define the second magnet 21 and the fourth magnet 22 in a space surrounded by the mounting ring 24 and the top cover 23.

In the present embodiment, as shown in fig. 5A and 5B, the folding support mechanism 3 includes a sheet-shaped first fixing portion 31a, a second fixing portion 31B, a support portion 32, a first rotating portion 33, a second rotating portion 34, and a third magnet 35 that are assembled together. As described above, the first fixing portion 31a and the second fixing portion 31b are each fixed to the base upper cover 12. The support portion 32 may be fixed to the bottom of the cap recess 23c of the cap 2 by surface bonding or the like. Both ends of the first rotating portion 33 are rotatably connected to one end of the first fixing portion 31a and one end of the supporting portion 32, respectively, and both ends of the second rotating portion 34 are rotatably connected to one end of the second fixing portion 31b and the other end of the supporting portion 32, respectively. Thus, the fixed portion (the first fixed portion 31a and the second fixed portion 31 b), the supporting portion 32, the first rotating portion 33, and the second rotating portion 34 are actually configured as a four-bar mechanism. As shown in fig. 1C and 5A, in the folded state, the support portion 32, the first rotating portion 33, and the second rotating portion 34 are located between the base body 1 and the spin cover 2 in the axial direction of the support assembly, the support portion 32 and the second rotating portion 34 are located on the same plane, and the support portion 32 and the first rotating portion 33 are arranged in parallel with each other and stacked in the axial direction. As shown in fig. 2D and 5B, in the unfolded state, the support portion 32 and the first rotating portion 33 are parallel to each other and together form a first frame, the second rotating portion 34 forms a second frame, and the fixing portion forms a third frame. The first frame, the second frame and the third frame form a bracket structure of the triangular bracket.

As shown in fig. 5B, one third magnet 35 is provided and the third magnet 35 is a permanent magnet, and the third magnet 35 is formed in an arc shape in shape-fit with the second magnet 21 and provided to the first rotating portion 33. As shown in fig. 1C, in the folded state, the third magnet 35 is separated from the other magnets. As shown in fig. 2D, in the deployed state, the third magnet 35 magnetically engages with the second magnet 21, thereby maintaining the support assembly in the deployed state.

In the present embodiment, the folding support mechanism 3 is made of nylon cloth and a sheet-shaped metal skeleton (e.g., manganese steel skeleton). Specifically, the first frame 32i is interposed between the two nylon cloths forming the support portion 32, and the second frame 34i is interposed between the two nylon cloths forming the second rotation portion 34, whereby the structural strength of the support portion 32 and the second rotation portion 34 can be improved. It is understood that the third magnet 35 is provided to the first rotating portion 33, and the third magnet 35 also functions as a skeleton in practice.

The process of switching the support assembly between the folded state and the unfolded state according to an embodiment of the present application is described as follows.

When it is necessary to switch the support assembly from the folded state toward the unfolded state, the operator's finger may be inserted into the lid opening recess 12n of the base 1, and a driving force in the counterclockwise direction in fig. 1C is applied to the outer peripheral portion of the rotary lid 2 to overcome the magnetic attraction force between the first magnet 11 and the second and fourth magnets 21 and 22. Thereafter, the entire cap 2 is rotated relative to the base 1 to drive the folding support mechanism 3 to perform the unfolding operation. Specifically, the top cover 23 rotates the support portion 32 around the end portions connected to the first rotating portion 33 and the second rotating portion 34, respectively, such that the first rotating portion 33 rotates around the end portion connected to the first fixing portion 31a in the clockwise direction in fig. 1C, and the second rotating portion 34 rotates around the end portion connected to the second fixing portion 31b in the clockwise direction in fig. 1C, until both the support portion 32 and the first rotating portion 33 are formed in a parallel arrangement as shown in fig. 2D, whereby the support assembly is converted to the unfolded state shown in fig. 2D based on the linkage of the four-bar linkage formed by folding the support assembly 3. As shown in fig. 2D, in the unfolded state, the first central axis L1 of the base 1 and the second central axis L2 of the cap 2 are coplanar and intersect at a predetermined angle, the second magnet 21 is magnetically engaged with the third magnet 35, and the folding support mechanism 3 is formed in a bracket structure of a tripod (cross section is formed in a triangular shape).

When it is desired to switch the support assembly from the unfolded state to the folded state, the operator's finger may apply a driving force to the end of the rotary cover 2 remote from the base 1 in a clockwise direction in fig. 2D to overcome the magnetic attraction force between the second magnet 21 and the third magnet 35. Thereafter, the entire cap 2 is rotated relative to the base 1 to drive the folding support mechanism 3 to perform the folding operation. Specifically, the top cover 23 rotates the supporting portion 32 around the end portions connected to the first rotating portion 33 and the second rotating portion 34, respectively, such that the first rotating portion 33 rotates around the end portion connected to the first fixing portion 31a in the counterclockwise direction in fig. 2D, and the second rotating portion 34 rotates around the end portion connected to the second fixing portion 31b in the counterclockwise direction in fig. 2D, until both the supporting portion 32 and the second rotating portion 34 are formed in the same plane layout as shown in fig. 1C, thereby causing the supporting assembly to shift to the folded state shown in fig. 1C based on the linkage of the four-bar linkage formed by folding the supporting assembly 3. As shown in fig. 1C, in the folded state, the first central axis L1 of the base body 1 and the second central axis L2 of the spin cover 2 are collinear, the first magnet 11 is magnetically engaged with the second magnet 21 and the fourth magnet 22, and the folding support mechanism 3 is formed in a flat plate configuration.

The number and arrangement of the first, second, third and fourth magnets 11, 21, 35 and 22 provided in the present application are not limited to those described in the above embodiments, and other numbers and arrangements may be employed as long as the first, second and third magnets 11, 21 and 22 can maintain the support assembly in the folded state, and the second, third and third magnets 21, 35 can maintain the support assembly in the unfolded state.

In an alternative solution, the fourth magnet 22 may be omitted, and the solution of the support assembly of the application can be implemented by providing only the second magnet 21.

It will be appreciated that the shape of the base 1 and the screw cap 2 is not limited to a disc shape, and that other shapes may be used. At the connection points between the different parts of the folding support mechanism 3, it is possible to form the points of reduced thickness or to form a groove configuration so that the different parts of the folding support mechanism 3 can rotate around such connection points.
