Furthermore, the terms "first," "second," and the like, as used herein, are intended to distinguish one element from another, and not necessarily to distinguish between order and importance.

As shown in fig. 1 to 8, the present disclosure provides a support stand capable of supporting a portable electronic device in an open state, so that the electronic device is adapted to diversified usage scenarios. The electronic device includes, but is not limited to, a notebook computer, a tablet computer, a mobile phone, a personal digital assistant and other mobile devices or an accessory device such as a keyboard case or a case of a terminal device. The support of the present disclosure comprises a base 1, a second carrier 2, a first support 4 and a locking mechanism 5. The second carrier 2 is rotatably connected to the first carrier 1 via a rotary shaft 3, i.e. the second carrier 2 can be rotated relative to the first carrier 1 for folding or unfolding. The second carrier 2 can be used as a protective cover for the electronic device, and the second carrier 2 in the open state can also be used as a supporting platform for the electronic device.

In the embodiment shown in fig. 1, the second carrier 2 is configured plate-like in order to increase the carrying area. It should be noted that the drawings are not intended to limit the shape of the second carrier 2 in any way as long as it can carry electronic equipment, and can be applied to the present disclosure. Likewise, the first support 4 can also be embodied in the form of a plate.

The first supporting part 4 can be arranged on the back of the second bearing part 2 in a linkage manner with the second bearing part 2, when the second bearing part 2 rotates and is folded relative to the first bearing part 1, as shown in fig. 3, the first supporting part 4 is attached to the back of the second bearing part 2, and at the moment, the second bearing part 2 is in a folded state, so that the space is saved and the storage is convenient; as shown in fig. 1, when the second carrier 2 is rotated and opened relative to the first carrier 1, the first supporting member 4 is angled to the second carrier 2 to support the second carrier 2. Here, the first supporting member 4 is linked with the second carrier 2, and along with the rotation of the second carrier 2, the first supporting member 4 can be automatically opened to support the second carrier 2 or be retracted, and there is no need to manually open the supporting plate after the second carrier 2 is turned over as in the prior art, and therefore, the supporting frame of the present disclosure improves the efficiency of operation.

To expand more usage scenarios, the support frame of the present disclosure is provided with a locking mechanism 5, as shown in fig. 2, the locking mechanism 5 is configured to maintain the first supporting member 4 in a position of abutting against the back of the second supporting member 2 during the rotation of the second supporting member 2 relative to the first supporting member 1, specifically, by providing the locking mechanism 5, the linkage between the first supporting member 4 and the second supporting member 2 is prevented. In some usage scenarios, the electronic device is used as a display, and at this time, the second carrier 2 needs to be supported by the first supporting member 4, while in other usage scenarios, the electronic device is used as a writing tool, and it is more convenient to place the electronic device horizontally, and at this time, the first supporting member 4 is required to be not opened therewith but to be always attached to the back of the second carrier 2 during the process of rotating and opening the second carrier 2.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: the first supporting part 4 can be arranged on the back of the second carrier 2 in a linkage manner with the second carrier 2, so that in the process of rotating the second carrier 2, the first supporting part 4 can be automatically opened along with the second supporting part to support the second carrier 2 or be folded, and the operation efficiency is improved. Meanwhile, by operating the locking mechanism 5, the first supporting part 4 can be optionally not opened even in the process of rotating the second bearing part 2, and the use scene of the terminal equipment is expanded.

As shown in fig. 1 to 3, a first end of the first supporting member 4 is hinged to the second bearing member 2, and a second end of the first supporting member 4 is formed as a swinging end. When the first supporting member 4 is attached to the back of the second supporting member 2, the position of the swing end corresponds to that of the rotating shaft 3, and the locking mechanism 5 is configured to be able to sequentially penetrate through the swing end and the rotating shaft 3. Specifically, when the second carrier 2 is rotated and opened relative to the first carrier 1, when the locking mechanism 5 does not penetrate through the swing end and the rotating shaft 3, the swing end and the rotating shaft 3 are in a disengaged state, so that the first support 4 can be freely opened, and when the locking mechanism 5 penetrates through the swing end and the rotating shaft 3 in sequence, the swing end and the rotating shaft 3 are locked together, and at this time, the swing end opening tendency of the first support 4 is restrained. Therefore, by operating the locking mechanism 5, it is possible to select whether the first supporting member 4 is opened or not when the second carrier 2 is rotated, thereby adapting to different usage scenarios.

As shown in fig. 4, the second supporting member 2 can be connected to the rotating shaft 3 through a third connecting member 323, that is, a first end of the third connecting member 323 is fixedly connected to the second supporting member 2, and a second end is rotatably connected to the rotating shaft 3, so as to realize the rotation of the second supporting member 2 relative to the first supporting member 1. The swing end of the first support member 4 may be provided with a fourth connecting member 33, that is, a first end of the fourth connecting member 33 is fixedly connected with the first support member 4, and a second end is provided for the locking mechanism 5 to penetrate through. In this embodiment, the locking mechanism 5 sequentially penetrates the second end of the fourth connecting member 33 and the second end of the third connecting member 323, that is, the locking mechanism 5 indirectly penetrates the swinging end of the first support 4 and the rotating shaft 3 through the third connecting member 323 and the fourth connecting member 33. It will be appreciated that in other embodiments, no connection may be provided, such that the locking mechanism 5 passes directly through the swing end and the shaft 3.

As an embodiment for realizing the locking mechanism 5, referring to fig. 4 and 5 together, the locking mechanism may include a fixed member 51, a moving member 52, and an operating member 53. The fixing element 51 is sleeve-shaped and is fixedly arranged on the first support 4, in particular at the pivot end of the first support 4, in the embodiment in which the fourth connection 33 is provided, the fixing element 51 can also be arranged on the fourth connection 33. The moving member 52 is slidably provided in the fixed member 51 in the axial direction. The moving member 52 is axially provided with a through hole into which the operating member 53 extends, and the inner peripheral surface of the through hole and the outer peripheral surface of the operating member 53 are provided with threads that are engaged with each other.

Referring to fig. 5 in detail, the operating member 53 may be configured to include an operating portion 531 and a lever portion 532, and the operating portion 531 is a knob, i.e., a linear motion of the moving member 52 is converted by a rotational motion of the operating member 53. The rotational operating member 53 occupies less space than the axial push-pull operating member 53. The outer peripheral surface of the stem 532 is provided with a first screw 5321, and the inner peripheral wall (i.e., the through-hole inner wall) of the mover 52 is provided with a second screw 5221 for engaging with the first screw 5321. Since the circumferential movement of the moving member 52 is restricted, the engagement between the first screw 5321 and the second screw 5221 is similar to a lead screw-nut mechanism, i.e., the moving member 52 is forcibly moved only in the axial direction with the rotation of the operating member 53 to thereby pass the swing end and the rotating shaft 3 or disengage the swing end and the rotating shaft 3.

To limit the circumferential movement of the moving member 52, the fixed member 51 and the moving member 52 may cooperate to form a limit structure. In some embodiments, as shown in fig. 5, the inner circumferential surface of the fixed member 51 is provided with a first limiting portion 511, and the outer circumferential surface of the moving member 52 is provided with a second limiting portion 521, wherein the first limiting portion 511 and the second limiting portion 521 may be configured as polygonal ribs. In other embodiments, the moving member 52 may be provided with a plurality of protrusions along the circumferential direction on the outer circumferential surface thereof, the fixing member 51 may be provided with a notch along the axial direction from the end thereof, the protrusions may slide along the axial direction in the notch, and the circumferential movement of the moving member 52 may be restricted due to at least two points of fixation.

The second carrier 2 of the present disclosure is also capable of achieving hovering at any angle. Wherein the shaft 3 may comprise a hovering section. In the embodiment shown in fig. 4, the main body of the spindle 3 is configured as a hollow shaft, and the hovering section is accommodated inside the spindle 3, and in particular, as shown in fig. 6, an accommodating groove 3213 may be provided in the spindle 3 to accommodate the hovering section. Alternatively, the rotating shaft may be segmented, that is, the rotating shaft 3 is axially segmented into a plurality of segments, at least one of which is used as the hovering section. The manner in which the hovering section is accommodated in the rotating shaft 3 may reduce the axial length of the rotating shaft 3.

The hovering section may comprise a first damping shaft 311 and a second damping shaft 312 which are rotatably fitted to each other, and optionally, the first damping shaft 311 and the second damping shaft 312 may be in-line damping shafts, and such damping shafts may utilize friction force during rotation to realize any hovering of the second bearing member 2. Wherein the second carrier 2 is connected with the first damping shaft 311 and can rotate along with the first damping shaft 311. It should be noted that the first and second damping shafts are not particularly limited, and for example, the second bearing member 2 may be configured to be connected to the second bearing member 312, and the second bearing member 2 may rotate along with the second damping shaft 312.

Furthermore, the rotating shaft 3 may further comprise a limiting section for limiting the maximum opening of the second load bearing member 2. The limiting section may include a first limiting member 321 and a second limiting member 322 rotatably engaged with each other. In the embodiment shown in fig. 6, the first limiting member 321 is configured as a part of a main body of the rotating shaft 3, and the second carrier 2 is connected to the second limiting member 322 and can rotate along with the second limiting member 322, for example, the second limiting member 322 is integrally formed with the third connecting member 323, and at this time, the second limiting member 322 is connected to the second carrier 2 through the third connecting member 323. The inner peripheral wall of the first limiting member 321 is provided with a limiting groove 3211 into which the second limiting member 322 is inserted and can rotate, and the limiting groove 3211 has a stopping portion 3212 for limiting the rotation angle of the second limiting member 322. The second limiting member 322 may be configured to be a circular arc-shaped protrusion, the limiting groove 3211 serves as a track in which the second limiting member 322 rotates, and the position of the stopping portion 3212 is reasonably designed to limit the opening of the second supporting member 2, for example, the electronic device is inclined at an optimal angle between 90 ° and 130 ° when in use, and therefore, the maximum opening of the second supporting member 2 may be designed to be 130 °.

As a way of achieving the linkage of the first supporting member 4 and the second carrying member 2, an ejecting structure 6 is disposed between the first supporting member 4 and the second carrying member 2, and when the second carrying member 2 rotates to a preset angle relative to the first carrying member 1, the ejecting structure 6 can provide an elastic force for driving the first supporting member 4 to the open position. For example, it is possible to make the first supporting member 4 still fit to the back of the second carrier 2 when the second carrier 2 rotates by 0-90 ° by a reasonable design, and when the second carrier 2 rotates by more than 90 °, the first supporting member 4 is opened under the action of the ejecting structure 6 to support the second carrier 2. Alternatively, as shown in fig. 7, the pop-up structure 6 may include a first connecting member 61 for connecting with the second carrier 2, a second connecting member 62 for connecting with the first supporting member 4, and a connecting shaft 63 for hinging the first connecting member 61 and the second connecting member 62, wherein a torsion spring 64 is sleeved on the connecting shaft 63.

According to an embodiment of the present disclosure, as shown in fig. 2, the supporting frame may further include a second supporting member 7, the second supporting member 7 is slidably disposed on the first bearing member 1, and a first end of the second supporting member 7 is hinged to the first supporting member 4. Thus, a four-bar mechanism is formed when the first supporting member 4 and the second supporting member 7 are opened, and the stability of supporting the second loading member 2 is improved. When the first support 4 is opened, the second support 7 partially slides out of the first carrier 1, and when the first support 4 is retracted, the second support 7 is fully retracted into the first carrier 1. Optionally, the first carrier 1 may be provided with a sliding slot 12 for receiving the second support 7 for sliding the second support 7 therein. The slide groove 12 can be used to guide the direction of movement of the second support 7, improving the stability of the movement. In the embodiment shown in fig. 8, the second support 7 is configured as a bar.

As shown in fig. 1 and 2, the first carrier 1 is detachably provided with a keypad 11. The keyboard 11 is capable of communicative connection with an electronic device. For example, the keyboard and the electronic device 20 may communicate by means of, for example, bluetooth or infrared. According to various embodiments of the present disclosure, the support frame may be configured as a common support frame or a support frame with a keyboard, where the common support frame only provides support for the electronic device, and the support frame with the keyboard can support the electronic device and also can extend a use scenario through the keyboard 11, for example, in some use scenarios, a virtual touch keyboard of the electronic device is replaced by a physical keyboard, so that work efficiency and use experience can be improved. The keyboard 11 is configured to be detachable so that the stand can be switched between a normal mode and a keyboard-equipped mode.

According to a second aspect of the embodiments of the present disclosure, there is provided an apparatus using a support stand, which may be an electronic device, including the support stand in any of the embodiments. Electronic devices include, but are not limited to, mobile devices such as notebook computers, tablet computers, cellular phones, and personal digital assistants. In this case, the support frame and the electronic device are formed as a single device, or the support frame is formed as an integral part of the electronic device, wherein the support frame can be either fixedly connected or detachably connected to the electronic device.

According to a third aspect of the embodiments of the present disclosure, the apparatus may be an accessory device of an electronic device, including the support stand in any of the embodiments described above. In contrast to the electronic device of the second aspect of the present disclosure, the support frame is used as an expandable accessory device of the electronic device.
