Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, an embodiment of the present application provides an electronic device, which includes:
a body 1;
the rotating shaft 2 is connected with the body 1;
the supporting frame is connected with the rotating shaft 2 and can rotate relative to the body 1 through the rotating shaft 2, and the supporting frame comprises a base frame 3 and at least one supporting piece 4 which is arranged on the base frame 3 and can perform expansion or contraction movement relative to the base frame 3;
wherein the electronic device has at least a first pose and a second pose: when the electronic device is in the first posture, the at least one supporting piece 4 is in an expanded shape and forms a first included angle with the body 1, and when the electronic device is in the second posture, the at least one supporting piece 4 is in a contracted shape and forms a second included angle with the body 1.
The support frame in this embodiment enables the support frame to at least support the body 1 through the at least one support member 4, so that the body 1 can be at least vertically arranged on the bearing surface in the first posture or the second posture, and the use requirement of a user on the electronic device is met. At least one supporting member 4 of the supporting frame of the present embodiment can be matched to form an expanded shape or a contracted shape, so that a user can drive the supporting member 4 to be in the expanded shape or the contracted shape according to the use requirement, for example, the required placing angle of the body 1 relative to the bearing surface, and the use flexibility of the user is increased. The above-mentioned spreading shape may be formed by spreading the supporting member 4 relative to the supporting frame, for example, a certain end or a certain mass point of the supporting member 4 may be far away from a fixed base point on the supporting frame along with the movement of the supporting member 4, or the supporting member 4 may be moved relative to the supporting frame to form a spreading shape as a whole; the formation of the spreading shape can also be performed by the support element 4 itself, for example by deforming the support element 4 under the influence of external conditions, so that a part or all of it is moved at least relative to and away from the fixed base point of the support frame. Of course, the formation of the expanded shape may also include both of the above forms. When the supporting member 4 is expanded and contracted based on the above method, it may also be contracted relative to the supporting frame, or contracted by itself under the influence of the condition opposite to the former external condition, that is, the supporting member 4 can move so that at least the portion far from the fixed base point of the supporting frame can move to be close to the fixed base point of the supporting frame, thereby completing the final contraction and restoration of the supporting member 4. Through setting up support frame and support piece 4 to this kind of form, can make the user arrange in order, accomodate or go out when carrying electronic equipment, because at least one support piece 4 can be the shrink form, so reduced electronic equipment's whole volume, compare electronic equipment among the prior art, even with bulky and heavy supporting member's electronic equipment, electronic equipment in this embodiment is changeed in the user and accomodates, carries, has improved the user and has experienced to electronic equipment's use.
Further, as shown in fig. 1 and 2, the body 1 in the present embodiment has a first surface and a second surface opposite to each other, wherein the first surface is provided with an output device, such as a screen, a speaker, etc., and the second surface is provided with the above-mentioned supporting frame. When the electronic device is in the first posture or the second posture, the corresponding first included angles may be equal or different. For example, when the electronic device is in the first posture and the second posture, the base frame 3 does not drive the at least one supporting member 4 to rotate relative to the body 1 so as to change an included angle between the supporting member 4 and the body 1, but the at least one supporting member 4 moves along the expanding and contracting directions thereof so as to correspondingly form an expanded shape and a contracted shape. That is, the difference between the first posture and the second posture of the electronic device may only be the structural state of the at least one supporting member 4, and there is no change in the angles between the supporting member 4, the supporting frame and the body 1, so that the first included angle and the second included angle may be equal.
Further, when the first angle is different from the second angle, the first angle can be made larger than the second angle, for example, the second angle is 0 °, and the first angle is any one of the values larger than the second angle, including 30 °, 60 °, 100 °, and so on. It is also possible to make the first angle smaller than the second angle, for example 45 ° for the first angle, 80 ° for the second angle, etc. When the first included angle is larger than the second included angle, the first posture and the second posture meet at least one of the following conditions:
the first method comprises the following steps: the first posture comprises a posture when the body 1 and the support frame are in a spreading state, the second posture comprises a posture when the body 1 and the support frame are in a fitting state, and the first included angle and the second included angle are included angles between the body 1 and the support frame respectively; or
And the second method comprises the following steps: the first posture comprises a posture when the body 1 is stabilized on the bearing surface based on the support frame, the second posture comprises a posture when the body 1 is independently stabilized on the bearing surface, and the first included angle and the second included angle are respectively included angles between the body 1 and the support frame; or
And the third is that: the first posture comprises a posture when the body 1 forms a first included angle with the bearing surface based on the support frame, and the second posture comprises a posture when the body 1 forms a second included angle with the bearing surface in an unsupported state.
That is, the difference between the two postures in the first expression is that the included angle between the body 1 and the support frame is different; the difference between the two postures in the second expression is whether the body 1 is stably placed on the bearing surface by the support frame, namely whether the support frame supports the body 1; the difference between the two postures in the third expression is the difference of the included angle between the body 1 and the bearing surface under the support based on the support frame and the support not based on the support frame. The main body 1 and the supporting frame in this embodiment make the first posture and the second posture of the electronic device have a significant difference through at least one of the three expressions, so that the electronic device has at least two completely different using postures.
For example, the electronic device is a plate-shaped device such as a tablet computer and a slim-type audio device, the support frame is disposed at the bottom edge of the main body 1, the first posture of the electronic device may be a placing posture when the main body 1 is placed on the carrying surface in a direction inclined toward the support frame based on the support frame, and at this time, the base frame 3 and at least one support member 4 thereon may be pressed against the carrying surface so that the support frame can provide a stable supporting force for the main body 1, so that the main body 1 can be vertically disposed on the carrying surface under the supporting effect of the support frame. The user can conveniently enjoy audio data or video data output by the electronic equipment in the first posture. Or, the body 1 is rotated to make the first contained angle between body 1 and support piece 4 be 180, can be with the support frame clamping on the object that has clamping piece or crack during the user uses to make body 1 can be along vertical direction vertical location on this object, because when first gesture, support piece 4 is the expansion form, consequently can increase clamping area, improve stability. But also the user can turn the body 1 after the gripping according to his own needs so that the body 1 can be fixed to the object at an oblique angle. Further, the second posture of the electronic device may be a posture when the body 1 is attached to the support frame. That is, the second posture is that the support frame does not provide the holding power for the body 1 but rotates to the position that leans on mutually with the body 1, or sets up a storage tank that can be used for holding the support frame on the body 1 to make the rotatable state of accomodating to the storage tank of support frame, this state can make the electronic equipment appearance slimmer, and is small and exquisite, changes easily by the user and goes out to carry, or accomodates the arrangement.
When the first included angle is smaller than the second included angle, the first posture and the second posture of the electronic device can be postures when the body 1 can be obliquely placed on the bearing surface towards the direction of the support frame based on the support frame, and the two postures only have different inclination angles of the body 1 relative to the support member 4. For example, in the first posture, the second surface of the body 1 is closer to the bearing surface, and the standing degree is lower; in the second posture, the second surface of the body 1 is far away from the bearing surface, and the standing degree of the body 1 is higher.
Further, in this embodiment, when the electronic device is in the first posture, the at least one supporting element 4 is made to be in an expanded shape so as to increase a contact area between the supporting frame and the supporting surface, so as to provide a sufficient stable supporting force for the main body 1, and ensure that the main body 1 can be stably placed on the supporting surface in an inclined manner. Since the center of gravity of the main body 1 moves downward when the main body 1 tilts toward the supporting frame, in order to ensure that the main body 1 can be stably placed on a table, the supporting area between the main body 1 and the table should be increased, and the contact area between the main body 1 and the table in the tilting direction should preferably be increased, in this embodiment, the effect of increasing the contact area is achieved by expanding at least one supporting member 4. When the electronic device is in the second state, the at least one supporting member 4 is made to be in a contracted shape, as described above, so that the supporting frame can form a compact structure when the user wants to store or carry the electronic device, thereby providing convenience for the user. In addition, the support member 4 can be expanded or contracted to adjust the included angle of the body 1 relative to the bearing surface, so that the body 1 can be erected on the bearing surface to different degrees.
Further, when driving or controlling the movement of the at least one support 4 to assume the expanded or contracted state is achieved, the following two ways may be adopted:
in the first mode, an electric control mode is adopted;
for example, a controller may be provided in the main body 1, an angle detecting device electrically connected to the controller may be provided on the base frame 3 or the rotary shaft 2, and a driving device electrically connected to the controller may be provided on the base frame 3 or the main body 1. The angle detection device is used for detecting the rotation angle of the pedestal 3 or the rotating shaft 2, the controller is used for determining whether the detection result meets the condition or not, and driving the driving device according to the rotation angle when the condition is met, and the driving device is used for acting with the supporting piece 4 so as to drive the supporting piece 4 to be in an expansion shape or a contraction shape under the control of the controller. That is, the controller in this embodiment may control the movement of the at least one support 4 according to the rotation angle of the rotation shaft 2 or the base frame 3. For example, when the controller detects that the rotation angle of the rotating shaft 2 or the base frame 3 detected by the angle detecting device reaches a target value, such as 20 °, the driving device receives a trigger signal from the controller to drive the at least one supporting member 4 to move to expand or contract. The driving device is not unique, and may be, for example, an electromagnetic induction device, so that the driving device is powered on to generate a magnetic force after receiving a trigger signal, so as to drive the metal or the at least one supporting member 4 with the electromagnetic force to move; or the driving device can be a heating device, and when receiving the trigger signal, the driving device can be electrified to generate heat so as to drive at least one supporting piece 4 which can be heated and deformed to deform, or move due to deformation, and the like, and further form an expansion shape or a contraction shape.
Furthermore, instead of setting the angle detection device and the controller, two microswitches electrically connected to the driving device and the controller may be provided on the angle detection device, and a shifting block may be provided on the base frame 3 or the rotating shaft 2, so that when the base frame 3 and the rotating shaft 2 rotate to different target angles, the shifting block may touch the corresponding microswitch, so that the microswitch supporting member 4 may be turned on in the forward direction or the reverse direction, so that the driving device drives the supporting member 4 to move in the expansion direction or the contraction direction to form the expansion-shaped or contraction-shaped supporting member 4.
In the second mode, a mechanical transmission mode is adopted;
in specific implementation, a transmission mechanism respectively interacting with the rotating shaft 2 and the supporting member 4 for transmitting the power output by the rotating shaft 2 to the supporting member 4 may be disposed on the base frame 3. That is, when the rotation shaft 2 rotates, power is output, which is transmitted to the support 4 via the transmission mechanism, so that the support 4 can move into an expanded or contracted state based on the power output from the rotation shaft 2.
Specifically, the pivot 2 in this embodiment rotates and locates on body 1, can rotate body 1 relatively promptly, and 2 accessible installed parts 11 of pivot are installed on body 1, also can directly install on the body, and the one end of bed frame 3 is fixed on pivot 2, and user's accessible rotates bed frame 3 and drives pivot 2 and rotate, also directly control pivot 2 and rotate. For example, the rotating shaft 2 can be driven by a motor, the motor can be connected with an electric switch arranged on the body 1, and a user can control the motor to drive the rotating shaft 2 to rotate through the electric switch, namely, the user can drive the rotating shaft 2 to rotate in an electric control mode; or, a knob connected with the rotating shaft 2 may be arranged on the body 1, and a user may drive the rotating shaft 2 to rotate through the knob, that is, the user may drive the rotating shaft 2 to rotate through a mechanical manner, which is not unique.
Further, the structure of the transmission mechanism for realizing the transmission is not exclusive, for example:
structure one, drive mechanism includes:
a first gear 5 fixedly arranged on the rotating shaft 2;
the driving plate 6 is provided with a toothed key meshed with the first gear 5, the driving plate 6 is arranged on the base frame 3 in a sliding mode and acts on the at least one supporting piece 4, when the rotating shaft 2 rotates, the driving plate 6 can slide under the driving of the first gear 5, and then the at least one supporting piece 4 is driven or is in an expansion shape or a contraction shape.
For example, when the user drives the rotating shaft 2 to rotate, the first gear 5 is linked with the rotating shaft 2, and since the first gear 5 is meshed with the transmission plate 6, the transmission plate 6 can be driven to move along the expanding direction of the supporting member 4, and at this time, the supporting member 4 which is interacted with the transmission plate 6 can move under the action of the transmission plate 6, so as to form an expanding shape or a contracting shape. The number of the first gears 5 is not unique, and a plurality of first gears 5 can be arranged on the rotating shaft 2; the shape and the number of the transmission plates 6 are not unique, and the transmission plates can be two strip-shaped plates arranged side by side and the like; the functional relationship between the supporting member 4 and the driving plate 6 is not exclusive, and for example, the supporting member 4 and the driving plate 6 are connected, such as by connecting members to connect the supporting member 4 and the driving plate 6 in a fixed or detachable manner; or the driving plate 6 is in an abutting relationship, for example, two sides of the driving plate 6 abut against the supporting member 4 in different orientation relationships, so that the driving plate 6 can push the supporting member 4 to move together with the supporting member 4 regardless of moving along the expanding direction or the contracting direction of the supporting member 4, thereby driving the supporting member 4 to be in an expanding state or a contracting state.
In a second configuration, as shown in fig. 3 and 4, the transmission mechanism includes:
a first gear 5 fixedly arranged on the rotating shaft 2;
a second gear 7 fixedly provided on the base frame 3 and engaged with the first gear 5;
the transmission plate 6 is provided with a toothed key meshed with the second gear 7, and the transmission plate 6 is arranged on the base frame 3 in a sliding manner and acts with the supporting piece 4 so as to slide under the driving of the second gear 7 when the rotating shaft 2 rotates, and then the supporting piece 4 is driven to be expanded or contracted.
That is, the rotating shaft 2 drives the first gear 5, the second gear 7, the transmission plate 6 and the support member 4 to move in sequence, and finally the support member 4 can move to an expanded shape or a contracted shape.
Preferably, in order to increase the transmission efficiency, especially when the transmission plate 6 is an elongated plate, the second gear 7 can act on the middle of the elongated plate, so that the support 4 can be driven to move to an expanded or contracted state by moving the elongated plate only a small distance, and the transmission mechanism in this embodiment further comprises a third gear 8. The third gear 8 is at least one, and is arranged on the base frame 3 and positioned between the first gear 5 and the second gear 7 for transmission. The base frame 3 may be a rectangular frame matching the shape of the transmission plate 6 as shown in the figure, or may be in other shapes, but at least needs to include two side plates disposed opposite to each other for installing the second gear 7 and the third gear 8. As shown in the figure, in the present embodiment, the distance between the first gear 5 and the plate surface of the support 4 is greater than the distance between the third gear 8 and the plate surface of the support 4, and the distance between the third gear 8 and the plate surface of the support 4 is greater than the distance between the second gear 7 and the plate surface of the support 4. That is, when body 1 erects on the desktop based on the carriage, the height of first gear 5, third gear 8, second gear 7 relative desktop is steadilyd decrease in proper order, so set up not only can reach high-efficient driven effect, can further play supplementary effect for the support frame to body 1's support moreover.

Further, as shown in fig. 3, 4 and 5, the number of the supporting members 4 in the present embodiment is plural, and the plural supporting members 4 are, for example, plural semi-circles whose radii are sequentially increased and are the same circle center, or plural rectangular frames whose sizes are increased in equal proportion and one end is open, and the specific structural shape is not unique, as long as the plural supporting members 4 have similar structures, and the external sizes are sequentially decreased to be capable of being mutually overlapped and contracted. As shown in the figure, two adjacent supporting members 4 are connected in a sliding manner, and the first supporting member 4 located at the innermost side of the plurality of supporting members 4 which are overlapped with each other is fixedly connected with the base frame 3, so that the position of the first supporting member is not changed and cannot move along with the movement of other supporting members 4; the second supporting piece 4 positioned at the outermost side is connected with the transmission plate 6; at least one support 4 between the first support 4 and the second support 4 is a third support 4. The first side of each third supporting member 4 is provided with a sliding block 10, the second side opposite to the first side is provided with a sliding groove 9, the first side of the first supporting member 4 is provided with the sliding groove 9, the second side of the second supporting member 4 is provided with the sliding block 10, between two adjacent supporting members 4, namely between any two adjacent supporting members 4 in all the supporting members 4, the sliding block 10 of the supporting member 4 positioned on the outer side is slidably arranged in the sliding groove 9 of the supporting member 4 positioned on the inner side. When the driving plate 6 moves under the action of the rotating shaft 2, the driving plate 6 can drive the second supporting member 4 to move towards the expanding direction, at this time, the sliding block 10 of the second supporting member 4 moves along the sliding groove 9 of the third supporting member 4 connected with the sliding block 10, and drives the third supporting member 4 to move towards the expanding direction after the sliding block 10 abuts against the end part of the sliding groove 9, the sliding block 10 of the third supporting member 4 moves in the sliding groove 9 of another adjacent third supporting member 4, and drives the third supporting member 4 to move towards the expanding direction after the sliding block 10 touches the bottom, and so on, until the third supporting member 4 connected with the first supporting member 4 slides in place along the sliding groove 9 of the first supporting member 4, the supporting frame is in the expanding state with the largest expanding angle at this time.
Certainly, the user can only expand part of the supporting members 4 according to actual needs, so that the expansion angle of the supporting frame is between the maximum value and the minimum value, for example, when the supporting angle of the body 1 is adjusted, the included angle between the body 1 and the desktop is inversely proportional to the expansion angle of the supporting frame, that is, the smaller the included angle is, the larger the inclination degree of the body 1 is, the larger the expansion area of the supporting members 4 in the supporting frame is, and vice versa, the smaller the expansion area is. When the rotating shaft 2 rotates in another direction, i.e. the supporting members 4 are to be contracted, the driving plate 6 first moves in the contracting direction and drives the second supporting member 4 connected thereto to move in the contracting direction along the sliding groove 9 of the adjacent third supporting member 4, then the third supporting member 4 adjacent to the second supporting member 4 drives the third supporting member 4 connected thereto to move in the contracting direction, and so on, until the third supporting member 4 connected to the first supporting member 4 moves to a position attached to the first supporting member 4, at this time, the contracting of all the supporting members 4 is completed, and the supporting frame is in the contracting state.
