Referring to fig. 1 to 6, an exemplary adapting structure 10 and a foldable stand employing the same according to the present application will now be described.
Referring to fig. 4 and 5, the adapting structure 10 includes a connecting component 11 and a magnetic component 12.
The connecting assembly 11 comprises a connecting sheet 111, and a first panel 112 and a second panel 113 fixedly connected with the connecting sheet 111, wherein the connecting sheet 111 is provided with an axis extending along the length direction, the upper surface of the connecting sheet 111 is provided with a first installation position and a second installation position which are positioned at two sides of the axis, and the first panel 112 and the second panel 113 are respectively arranged at the first installation position and the second installation position. The connecting piece 111 is made of a flexible material and can be bent along an axis. The first panel 112 and the second panel 113 are made of a rigid material, and the first panel 112 and the second panel 113 are independent from each other. When the connecting piece 111 is bent along the axis, the first panel 112 and the second panel 113 located thereon rotate relatively.
The connecting sheet 111 is capable of being bent along the axis to switch between a flattened state and a bent state, and when the connecting sheet 111 is in the flattened state, the first panel 112 and the second panel 113 are placed horizontally; when the connecting piece 111 is in the bent state, the side surface of the first panel 112 facing the second panel 113 and the side surface of the second panel 113 facing the first panel 112 are abutted against each other, including the outer edge of the side surface of the first panel 112 facing the second panel 113 being directly or indirectly abutted against the side surface of the second panel 113 facing the first panel 112, and the outer edge of the side surface of the second panel 113 facing the first panel 112 being directly or indirectly abutted against the side surface of the first panel 112 facing the second panel 113. The angle between the first panel 112 and the second panel 113 is an obtuse angle.
The magnetic attraction assembly 12 comprises a first magnetic part 121 arranged on the first panel 112 and a second magnetic part 122 arranged on the second panel 113, and the first magnetic part 121 and the second magnetic part 122 are magnetically attracted and positioned on two sides of the axis.
For convenience of description, the first panel 112 and the second panel 113 are defined as being disposed left and right. When the connection piece 111 is in the flattened state, the connection piece 111 is in the horizontally extended state. The first panel 112 and the second panel 113 are placed horizontally. The right surface of the first panel 112 is a first pressing surface, and the left surface of the second panel 113 is a second pressing surface. When the connecting sheet 111 is in a flattened state, the first abutting surface and the second abutting surface enclose to form a gap channel 101 extending along the axial direction, so that when the left side and the right side of the connecting sheet 111 are bent upwards, two opposite sides of the first panel 112 and the second panel 113 can rotate upwards along the axial direction to be close, in other words, the gap channel 101 avoids the upward rotation and close movement of the first panel 112 and the second panel 113. When the first panel 112 and the second panel 113 abut, that is, when the first abutting surface abuts against the second abutting surface, the first abutting surface limits the second panel 113 to continue to rotate upwards. The first panel 112 and the second panel 113 form an obtuse angle.
The first magnetic member 121 is disposed on the first panel 112, the second magnetic member 122 is disposed on the second panel 113, and the first magnetic member 121 and the second magnetic member 122 magnetically attract each other to drive the first panel 112 and the second panel 113 to rotate upwards around the axis and close together. It will be appreciated that as the first and second panels 112, 113 are rotated upwardly, the width of the gap channel 101 is narrower until the first and second panels 112, 113 abut one another. The attraction force of the first magnetic member 121 and the second magnetic member 122 increases as the gap passage 101 narrows, and reaches a maximum when the first panel 112 and the second panel 113 abut against each other. At this time, the adsorption force presses the first panel 112 and the second panel 113 against each other to be difficult to separate under the non-external force, thereby achieving the relative fixation of the first panel 112 and the second panel 113. When the connecting piece 111 is in the flattened state, the attraction force of the first magnetic piece 121 and the second magnetic piece 122 is smaller than the gravity of the first panel 112 and the second panel 113, so that the first panel 112 and the second panel 113 are in a horizontal placement state.
When the switching structure 10 of the present embodiment is applied to a foldable stand, referring to fig. 1 to 3, the foldable stand includes the switching structure 10 and a keyboard 30, the keyboard 30 is rotatably connected to a second panel 113 of the switching structure 10, and the first panel 112 is used for fixing the tablet pc 20. Referring to fig. 3, when the foldable stand is in the storage state, the first panel 112 and the second panel 113 are horizontally stacked on the keyboard 30, and the tablet pc 20 is located between the first panel 112 and the keyboard 30. Referring to fig. 2, when the foldable stand is in the use state, the second panel 113 rotates upward to form an acute angle with the keyboard 30, the first panel 112 rotates upward to form an obtuse angle with the second panel 113, and the tablet pc 20 is fixed by the first panel 112 to form an inclined state with an elevation angle greater than 90 degrees (an angle between the display surface and the horizontal plane), so as to be convenient for a user to read. In the illustrated structure, the keyboard 30 is rotatably connected to the second panel 113 through a hinge structure (the hinge structure includes a pin, and a first rotating lever and a second rotating lever which rotate around the pin, the first rotating lever and the second rotating lever are respectively connected to the second panel 113 and the keyboard 30), and the pin is provided with a damper to maintain the rotated position of the first rotating lever and the second rotating lever after the first rotating lever is rotated to a specific angle. In the illustrated structure, the surface of the adapting structure 10 facing the tablet pc 20 is provided with an inner protection layer 42, and the material of the inner protection layer 42 may be nylon or microfiber. The foldable support is provided with an outer protective layer 41 on the outer sides of the switching structure 10 and the keyboard 30, and the outer protective layer 41 can be made of PU materials. Referring to fig. 6, the outer protection layer 41 covers the outer sides of the first panel 112 and the second panel 113 and is embedded into the gap channel 101, so as to prevent the first panel 112 and the second panel 113 from protruding upwards when rotating upwards to be close together, thereby affecting the appearance. It will be appreciated that in the case of the coating with the outer protective layer 41, the abutment of the first panel 112 and the second panel 113 is achieved by the bending abutment of the outer protective layer 41 in the region of the gap channel 101.
In this embodiment, a plurality of magnets are disposed on the first panel 112, and the magnets are attracted to the magnets disposed in the tablet pc 20 to realize detachable connection between the first panel 112 and the tablet pc 20. The tablet personal computer 20 is heavier than the adapting structure 10, and in the case that the tablet personal computer 20 is connected to the first panel 112, the gravity of the tablet personal computer 20 can improve the relative stability of the foldable stand in the storage and use states. Specifically, when the foldable stand is in the storage state, the display surface of the tablet pc 20 faces the keyboard 30, and the gravity of the tablet pc 20 increases the resistance of the first panel 112 to rotate upwards, so as to improve the stability of the foldable stand. When the foldable stand is in the use state, the gravity of the tablet personal computer 20 is converted into the pressure of the first panel 112 against the second panel 113, and the pressure and the adsorption force of the magnetic assembly are together improved, so that the resistance of the first panel 112 to reverse overturning is improved, and the stability of the foldable stand is improved.
In this embodiment, referring to fig. 2, when the connecting piece 111 is in a bent state, an included angle B between the first panel 112 and the second panel 113 is an obtuse angle. The lower surface of the first panel 112 is used for fixing the tablet personal computer 20, the included angle between the first panel 112 and the horizontal plane is an acute angle, and the first panel extends in a direction away from the keyboard, so that the display surface of the tablet personal computer 20 is inclined upwards to be beneficial to reading. It will be appreciated that the angle between the first panel 112 and the horizontal plane is equal to the angle B between the first panel 112 and the second panel 113 minus the angle between the second panel 113 and the horizontal plane. In the state that the second panel 113 is perpendicular to the horizontal plane, the included angle B between the first panel 112 and the second panel 113 is an obtuse angle, so that the inclined state of the first panel 112 can be ensured. In practical use, to raise the tablet pc 20 and combine the stability of the structure, the angle between the second panel 113 and the horizontal plane in the use state is preferably 60 ° -70 °. The included angle B between the first panel 112 and the second panel 113 is preferably 150 ° to 170 °
By the above, the switching structure 10 provided in this embodiment realizes the rotation connection and the limit of the first panel 112 and the second panel 113 through the design of the first panel 112, the second panel 113 and the connecting sheet 111, and realizes the relative stability of the first panel 112 and the second panel 113 in the bending state of the connecting sheet 111 through the arrangement of the magnetic component 12, thereby achieving the effects of simplifying the structure and reducing the production cost. The foldable support adopting the switching structure 10 can meet the requirements of the storage and use states of the tablet personal computer 20.
In another embodiment of the present application, the gap channel 101 is V-shaped, trapezoidal or rectangular in cross-section. It will be appreciated that the angle B between the first panel 112 and the second panel 113 is determined by the position where the first pressing surface and the second pressing surface abut against each other. The area where the first panel 112 and the second panel 113 are abutted may be a straight line or a plane. The positions of the pressing lines of the first panel 112 and the second panel 113 on the section perpendicular to the axis are named as a first end point and a second end point, and the included angles formed by the connecting lines of the first end point and the second end point and the axis are complementary angles of the included angle B. When the area where the first pressing surface and the second pressing surface press against each other is a plane other than a straight line, the first pressing surface and the second pressing surface are straight lines on a section perpendicular to the axis. The included angle of the two straight lines is the complement angle of the included angle B.
Preferably, when the connecting piece 111 is in a bent state, the first pressing surface and the second pressing surface are parallel and mutually pressed. In this design, the first panel 112 and the second panel 113 are in contact with each other in a surface, so that the pressure applied to the first panel 112 and the second panel 113 when they are in contact with each other can be reduced, and the stability of the contact between the first panel 112 and the second panel 113 can be improved, as compared with the line contact. When the cross section of the gap channel 101 is V-shaped and the connecting piece 111 is in a bent state, the first pressing surface and the second pressing surface are parallel and mutually pressed, and the included angle between the two side surfaces of the gap channel 101 is the complement angle of the included angle B. The included angle B between the first panel 112 and the second panel 113 is preferably 150 ° to 170 °, and the included angle between the two side surfaces of the gap channel 101 is preferably 10 ° to 30 °. The included angle may be further selected by those skilled in the art to be 10 °, 12 °, 14 °, 15 °, 17 °, 19 °, 20 °, 21 °, 23 °, 25 °, 26 °, 27 °, 28 °, 30 °, etc., without limitation.
In this embodiment, the first magnetic member 121 and the second magnetic member 122 are symmetrically disposed. It will be appreciated that the larger the opposing surfaces of the first magnetic member 121 and the second magnetic member 122, the greater the attraction force. The smaller the distance between the first magnetic member 121 and the second magnetic member 122, the greater the attraction force.
The first magnetic member 121 and the second magnetic member 122 may be provided at both upper ends of the gap channel 101, or may cover both side surfaces of the gap channel 101. The arrangement of the first magnetic member 121 and the second magnetic member 122 close to the gap channel 101 is advantageous in improving the attraction force of the first magnetic member 121 and the second magnetic member 122 in the bent state of the connecting piece 111.
Preferably, the first magnetic member 121 and the second magnetic member 122 are attached to both side surfaces of the gap channel 101. Specifically, the first panel 112 has a first accommodating groove for accommodating the first magnetic element 121 on the first pressing surface, and the second panel 113 has a second accommodating groove for accommodating the second magnetic element 122 on the second pressing surface. This arrangement can reduce the distance between the first magnetic member 121 and the second magnetic member 122, thereby improving the attraction force of the first magnetic member 121 and the second magnetic member 122 in the bent state of the connecting piece 111.
Referring to fig. 6, the upper groove wall of the first accommodating groove extends to the upper surface of the first panel 112 and the lower groove wall thereof extends to the lower surface of the first panel 112; the upper groove wall of the second receiving groove extends to the upper surface of the second panel 113 and the lower groove wall thereof extends to the lower surface of the second panel 113. This arrangement is advantageous in that the surface area of the first magnetic surface and the second magnetic member 122 facing each other is increased, thereby increasing the attraction force of the first magnetic member 121 and the second magnetic member 122 in the bent state of the connection piece 111.
In another embodiment of the present application, referring to fig. 6, a first fixing groove for embedding the connecting piece 111 is formed in the first panel 112 at the first mounting position, and a second fixing groove for embedding the connecting piece 111 is formed in the second panel 113 at the second mounting position. The arrangement is such that the connection sheet 111 is hidden within the first and second panels 112 and 113 without protruding from the lower surfaces of the first and second panels 112 and 113. In the case of being covered with the inner protective layer 42, the inner protective layer 42 is made flat, beautiful, and less prone to dirt and abrasion.
In another embodiment of the present application, referring to fig. 5, the first magnetic member 121 and the second magnetic member 122 are plural and spaced along the axis. All the first magnetic pieces 121 on the first pressing surface have the same magnetic pole, and all the second magnetic pieces 122 on the second pressing surface have the same magnetic pole. This arrangement can reduce interference between the magnetic members. In other embodiments, the first magnetic member 121 and the second magnetic member 122 may also be stripe-shaped and extend in the axial direction.
In another embodiment of the present application, the connecting piece 111 is a metal piece, the connecting piece 111 can be elastically bent, and when in a bending state, the elastic restoring force of the connecting piece 111 is smaller than the adsorption force of the magnetic attraction assembly 12. The metal sheet is selected as the connecting sheet 111, and has good fatigue resistance, so that the service life of the connecting sheet 111 is prolonged. In other embodiments, the connection piece 111 may also be made of fiber cloth or other flexible materials.
In another embodiment of the present application, referring to fig. 7, the connecting piece 111 has a plurality of through holes 102 at least at the axis. By providing the through holes 102, the flexibility of the metal sheet is improved. In the structure shown in fig. 7, the connecting piece 111 extends on both sides along the axis to form a rectangular perforated area in which each through hole 102 is disposed. The number and size of the through holes may be set according to actual needs by those skilled in the art, and are not limited herein.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
