Obviously, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] The foldable and collapsible electronic device stand of the preferred embodiment of the present utility model, such as Figure 1-8As shown in the figure, it includes a clamping seat 10. A first arm 20 is provided on the clamping seat 10. A first receiving groove 30 is formed by enclosing the upper surface of the clamping seat 10 and one side wall of the first arm 20. A second arm 40 that can be bent into the first receiving groove 30 is provided on the first arm 20; A foldable third arm 50 is provided on the second arm 40, and a clamping assembly 60 is provided on the third arm 50; When the storage is in place, both the third arm 50 and the clamping assembly 60 are stored in the first receiving groove 30; Among them, the clamping seat 10 is rectangular in shape. The first arm 20 is rectangular and its width is the same as the length of the clamping seat 10 and they are perpendicular to each other. Correspondingly, the second arm 40 is also rectangular and its width is the same as the width of the first arm 20. After the complete assembly, the clamping seat 10, the first arm 20 and the second arm 40 together form a regular quadrangular prism structure to improve the overall aesthetic degree and make it more convenient for storage and carrying;

[0032] In this solution, a storage structure is formed by the first arm 20 and the clamping seat 10, making the overall structure layout compact. After folding and storing, the clamping assembly 60 and the third arm 50 can be stored in the first receiving groove 30. Compared with the prior products, to a certain extent, it can effectively prevent the movement of the clamping assembly 60, and can also play a role in protecting the clamping assembly 60 during the storage process. After storage, the volume is small and convenient to carry.

[0033] In this embodiment, in the storage state, the included angle between the second arm 40 and the first arm 20 ranges from 0 to 30 degrees to ensure that the clamping assembly 60 and the third arm 50 can be completely stored in the first receiving groove 30. As a preference, the included angle between the first arm 20 and the second arm 40 in the storage state is zero degree, that is, the first arm 20 and the second arm 40 are parallel, so that the clamping seat 10, the first arm 20 and the second arm 40 are arranged outside the third arm 50 and the clamping assembly 60.

[0034] In this embodiment, the clamping assembly 60 includes a first clamping block 61 provided at one end of the third arm 50, an extension arm 62 slidably connected in parallel with the third arm 50, a second clamping block 63 provided at the end of the extension arm 62 away from the first clamping block 61, and a first elastic member 64 that provides an elastic force for the extension arm 62 towards the first clamping block 61; By providing the extension arm 62 on the third arm 50, it can adapt to electronic devices of different sizes and widths. For example, when the clamped electronic device changes from a mobile phone to a tablet, the extension arm 62 can be pulled out and the tablet can be clamped and fixed on the third arm 50 through the cooperation of the first clamping block 61 and the second clamping block 63. During the clamping process, the first elastic member 64 can ensure the stability of the clamping.

[0035] In addition, in order to further reduce the overall thickness of the bracket after storage, the first clamping block 61 and the third arm 50 can be folded, and the second clamping block 63 and the extension arm 62 can be folded when stored and unfolded when used.

[0036] In this embodiment, the extension arm 62 is U-shaped and its two arms are respectively located on both sides of the third arm 50. The two arms of the extension arm 62 are connected to the third arm 50 in parallel and sliding manner through the guide slide bar 70. The special shape of the extension arm 62 can make it more stable during its sliding process. At the same time, it can increase the sliding friction between the extension arm 62 and the third arm 50, and play a role in damping the sliding connection. In addition, the width of the third arm 50 can be reduced to facilitate keeping the width of the extension arm 62 the same as that of the first arm 20. While ensuring the stability of the extension arm 62, the width of the bracket is further reduced, making the overall structural design of the bracket more compact, so that the first arm 20, the second arm 40 and the third arm 50 are stored to form a rectangular parallelepiped structure as a whole, which not only makes the user feel more comfortable to hold, but also makes it more convenient to store the whole. Whether it is put in a pocket, a backpack or a drawer, it only takes up a small space.

[0037] In this embodiment, the third arm 50 is provided with a first guide slot 51 corresponding to the guide slide bar 70, the depth of the first guide slot 51 is less than the width of the guide slide bar 70, and the inner wall of the extension arm 62 is provided with a second guide slot 621 adapted to the guide slide bar 70, so that the relative side walls of the third arm 50 and the second arm 40 are closely attached after being assembled, ensuring the compactness of the structure while hiding the guide slide bar 70, further increasing the compactness of the structure of the bracket, and being more conducive to improving the neatness of the product appearance, which is helpful for product promotion.

[0038] In this embodiment, a second accommodating groove 71 is provided on the guide slide 70 along its length direction, and the first elastic member 64 is arranged in the second accommodating groove 71 to reasonably utilize the space occupied by the guide slide 70, further reduce the overall structure, and also protect the first elastic member 64; a stopper 6210 extending into the second accommodating groove 71 is provided on the inner wall of the second guide slide 621. When assembled in place, one end of the first elastic member 64 abuts against the stopper 6210, and the other end abuts against the side wall of the second accommodating groove 71 away from the stopper 6210, and the inner wall of the second guide slide 621 limits the first elastic member 64 in the second accommodating groove 71 to prevent the first elastic member 64 from deflecting during compression or expansion; wherein, the first elastic member 64 can be a spring, or a conventional structural member with elastic force such as a compression spring or a rubber band.

[0039] In this embodiment, the guide slide 70 is provided with a plurality of positioning grooves 72 along its length direction, and the third arm 50 is provided with a positioning pin 80 extending into the positioning groove 72; the third arm 50 is also provided with a push key 90 for pushing the positioning pin 80 out of or into the positioning groove 72, and a reset spring 100 for providing a reset force for the push key 90; the positioning pin 80 is connected to the push key 90, and when the extension arm 62 does not need to be unfolded, the elastic force provided by the reset spring 100 enables the push key 90 to keep the positioning pin 80 against the positioning groove 72, so that the extension arm 62 can be positioned at a suitable position through the positioning pin 80 after being unfolded.

[0040] Specifically, the length direction of the positioning pin 80 is perpendicular to the length direction of the third arm 50, and a side wall of the third arm 50 that is away from the first accommodating groove 30 is provided with an avoidance groove 52 along its width direction for avoiding the positioning pin 80, and the positioning groove 72 is located on a side wall of the guide slide 70 facing the avoidance groove 52, and a through hole 53 that is directly connected to the avoidance groove 52 is provided on the side wall of the third arm 50 facing the first accommodating groove 30, and the push key 90 is axially movably arranged inside the through hole 53, and the reset spring 100 is fixedly arranged in the through hole 53 and provides a reset for the push key 90 Force, when the assembly is completed, the two ends of the positioning pin 80 are respectively extended into the two relative positioning grooves 72 on the two arms of the extension arm 62. When the extension arm 62 needs to be extended, the push key 90 is pressed to compress the reset spring 100 so that the positioning pin 80 moves out of the positioning groove 72. At this time, the extension arm 62 can be slid. When the extended extension arm 62 needs to be positioned, the push key 90 is released to reset the push key 90 and the positioning pin 80 through the reset spring 100, so that the positioning pin 80 enters the positioning groove 72 again, and the extension arm 62 and the third arm 50 can be fixed and cannot slide.

[0041] In this embodiment, the second arm 40 and the third arm 50 are connected by the damping rotation of the first shaft 110 to achieve folding and unfolding. The second arm 40 and the third arm 50 are both perpendicular to the first shaft 110. This rotation connection method can prevent the third arm 50 from rotating toward the first arm 20 when stored, and prevent the third arm 50 from loosening and conflicting with the first arm 20 when it is unfolded or about to be stored in the first receiving groove 30, affecting the storage effect. In addition, the setting direction of the first shaft 110 can also make it convenient for the user to open the third arm 50 from one side to clamp the electronic device when the third arm 50 and the first arm 20 are both in the stored state, which can increase the adaptability of the use scenario.

[0042] In this embodiment, the first rotating shaft 110 is located on one end of the second arm 40 close to the second clamping block 63, so that the third arm 50 can be opened to the maximum length when the first arm 20 and the second arm 40 are stored.

[0043] In this embodiment, the first arm 20 and the second arm 40 are rotatably connected through a rotating shaft assembly 120. Specifically, the rotating shaft assembly 120 includes a second rotating shaft 122 and a third rotating shaft 123, as well as a fourth rotating shaft 124 and a fifth rotating shaft 125 arranged side by side; the fourth rotating shaft 124 is vertically and rotatably connected to the second rotating shaft 122, and the fifth rotating shaft 125 is vertically and rotatably connected to the second rotating shaft 122. In the initial state, the fourth rotating shaft 124, the fifth rotating shaft 125, and the second rotating shaft 122 form an H-shaped structure, and the fourth rotating shaft 124 and the fifth rotating shaft 125 can rotate relative to each other through the second rotating shaft 122, and can rotate to a state of being parallel to each other and skew-crossing; the fourth rotating shaft 124 is fixedly connected to the first arm 20, the third rotating shaft 123 is vertically and rotatably connected to the fifth rotating shaft 125, and the second arm 40 is fixedly connected to the third rotating shaft 123; during use, the second arm 40 and the first arm 20 can achieve 360-degree rotation in the same plane through the fourth rotating shaft 124 and the fifth rotating shaft 125, and the second arm 40 and the first arm 20 can achieve relative rotation in both the unfolded and stored states through the second rotating shaft 122 and the third rotating shaft 123, which is convenient for the second arm 40 and the third arm 50 to achieve multi-dimensional rotation adjustment. In the stored state, the second rotating shaft 122 can still rotate the third rotating shaft 123 around the third rotating shaft 123 towards the side away from the first receiving groove 30.

[0044] In this embodiment, a tightening member 130 that abuts against the fourth rotating shaft 124 is provided on the second rotating shaft 122. By adjusting the tightening force between the tightening member 130 and the fourth rotating shaft 124, the rotational damping between the fourth rotating shaft 124 and the second rotating shaft 122 can be conveniently adjusted. Specifically, an installation groove 1221 for installing the tightening member 130 is coaxially provided on the end surface of the second rotating shaft 122 facing the fourth rotating shaft 124. The tightening member 130 is provided with a shaft hole 131 for the fourth rotating shaft 124 to pass through. The fourth rotating shaft 124 passes through the installation groove 1221, and an elastic cushion block (not shown in the figure) or a spring is arranged between the bottom surface of the installation groove 1221 and the tightening member 130 to abut the fourth rotating shaft 124 against the inner wall of the shaft hole 131 on the second rotating shaft 122. When it is necessary to adjust the rotational damping between the fourth rotating shaft 124 and the second rotating shaft 122, only need to press the tightening member 130 into the installation groove 1221 and squeeze the cushion block or the spring, and then the tightening friction force between the fourth rotating shaft 124 and the inner wall of the shaft hole 131 of the second rotating shaft 122 can be reduced, and then the purpose of adjusting the rotational damping of the fourth rotating shaft 124 can be achieved.

[0045] In this embodiment, the clamping seat 10 includes a fixed clamping plate 11 and a movable clamping plate 12 disposed below the fixed clamping plate 11. Both the fixed clamping plate 11 and the movable clamping plate 12 are square and of the same size. The first arm 20 is vertically disposed on the upper surface of the fixed clamping plate 11 and is flush with the edge of the fixed clamping plate 11, so that the two form an L-shaped structure. The space between the opposite sides of the horizontal and vertical ends of the L-shaped structure forms the above-mentioned first receiving groove 30. Among them, the movable clamping plate 12 is slidably connected to the first arm 20 through a connecting member 150. A second elastic member 140 for providing a clamping force to the movable clamping plate 12 is further provided on the first arm 20. The second elastic member 140 can be a spring, a tension spring or an elastic belt, so as to clamp and fix the first arm 20 to other objects.

[0046] Further, in order to make the appearance of the bracket more neat and beautiful, generally, a receiving cavity 21 for installing the second elastic member 140 is provided inside the first arm 20. A guiding arm that can extend into the receiving cavity 21 is also vertically provided on the upper surface of the movable clamping plate 12. The guiding arm is the connecting member 150.
