Fig. 5 to 9 show a rotating connecting mechanism 16 according to an embodiment of the present invention. The rotation connecting mechanism 16 includes a supporting arm 160, and a first rotating shaft assembly 162 and a second rotating shaft assembly 164 respectively connected to two opposite ends of the supporting arm 160. The rotation connecting mechanism 16 is connected to the body 10 via the first rotating shaft assembly 162, and is connected to the clamping portion 18 via the second rotating shaft assembly 164.

The arm 160 includes a substantially elongated arm main body 1600, and a first mounting hole 1602 and a second mounting hole 1604 are respectively disposed at two opposite ends of the arm main body 1600 in an extending direction. The first mounting hole 1602 is used for mounting the first shaft assembly 162, and the second mounting hole 1604 is used for mounting the second shaft assembly 164.

The first shaft assembly 162 includes a first shaft 1620, a first fitting portion 1622 fixed to one end of the first shaft 1620, a first sleeve 1624 sleeved on the other end of the first shaft 1620, and a first fixing member 1626 fixed to the first sleeve 1624. The first fitting portion 1622 can be disposed in the first mounting hole 1602 so that the first rotating shaft assembly 162 and the support arm 160 are fixedly fitted together. In this embodiment, the first fitting portion 1622 is shaped to fit the first mounting hole 1602, and the fitting between the first fitting portion 1622 and the first mounting hole 1602 is shaped. It is understood that in other embodiments, the first engaging portion 1622 may be another fixed structure, and the first mounting hole 1602 is a suitable engaging structure, such as a snap-fit, a thread, an interference fit, etc., as long as the first shaft assembly 162 and the support arm are fixedly engaged together without moving relative to each other.

The rotational engagement between the first shaft 1620 and the first sleeve 1624 is a friction engagement to provide the damping, i.e., the relative rotation between the first shaft 1620 and the first sleeve 1624 can be achieved only when an external force is applied to the first shaft 1620 or the first sleeve 1624. When the applied external force is removed, the first shaft 1620 and the first sleeve 1624 remain relatively stationary. Since the first shaft 1620 is frictionally engaged with the first sleeve 1624 to generate damping without using a separate damping member, the structure is simple, the reliability is high, and the cost is low.

Referring to fig. 9, the first rotating shaft 1620 includes a first shaft portion 16200 connected to the first matching portion 1622, and a first protruding shaft 16202 extending from a side of the first shaft portion 16200 away from the first matching portion 1622 to a direction away from the first matching portion 1622, where the first protruding shaft 16202 is coaxial with the first shaft sleeve 1624. The first protruding shaft 16202 has a smaller radius than the first shaft portion 16200, so that a step (not labeled) is formed between the first shaft portion 16200 and the first protruding shaft 16202, and the first boss 1624 abuts against the first step. The first step includes a surface of the first shaft body part 16200 engaged with the first boss 1624 and an outer side surface of the first protruding shaft 16202. The outer side surface of the first protruding shaft 16202 is in friction fit with the inner side surface of the first sleeve 1624, and the first sleeve 1624 and the first protruding shaft 16202 can rotate relative to each other only when an external force is applied to the first rotating shaft 1620 or the first sleeve 1624. Preferably, the surface of the first shaft portion 16200 that engages with the first sleeve 1624 is also frictionally engaged with the inner sidewall of the first sleeve 1624, so as to further increase the rotational damping between the first shaft 1620 and the first sleeve 1624.

The first fixing piece 1626 is fixed to one side of the first sleeve 1624. In this embodiment, the first fixing piece 1626 extends from one side of the first sleeve 1624 in a direction substantially perpendicular to the first sleeve 1624. In this embodiment, an opening is formed in a side wall of the first shaft sleeve 1624, and the first fixing member 1626 is inserted into the opening and locked to the first shaft sleeve 1624 by a fixing device such as a screw.

The first fixing element 1626 is substantially right-angled and includes two first fixing portions 16260 perpendicular to each other. Each first fixing portion 16260 is provided with a first fixing hole 16262. The first fixing member 1626 is fixedly coupled to the body 10 by a fixing means such as a screw passing through the first fixing hole 16262. It is understood that the fixing manner of the first fixing member 1626 and the main body 10 is not limited to the fixing manner of the first fixing hole 16262 and the fixing device, and may be any suitable fixing manner, such as screwing, interference fit, snap fit, etc., as long as the first fixing member 1626 and the main body 10 can be fixedly connected.

The second rotating shaft assembly 164 includes a second rotating shaft 1640, a second fitting portion 1642 fixed to one end of the second rotating shaft 1640, a second shaft sleeve 1644 sleeved on the other end of the second rotating shaft 1640, and a second fixing member 1646 fixed to the second shaft sleeve 1644. The second engaging portion 1642 can be disposed in the second mounting hole 1604 so that the second rotating shaft assembly 164 and the supporting arm 160 are fixedly engaged together. In this embodiment, the second fitting portion 1642 is shaped to fit the second mounting hole 1604, and the fitting between the second fitting portion 1642 and the second mounting hole 1604 is shaped. It is understood that in other embodiments, the second engaging portion 1642 can be other fixed structures, and the second mounting hole 1604 can be a suitable engaging structure, such as a snap-fit, a screw-fit, an interference fit, etc., as long as the second rotating shaft assembly 164 and the support arm 160 can be fixedly engaged without moving relative to each other.

The rotation fit between the second rotating shaft 1640 and the second sleeve 1644 is a friction fit to generate the damping, that is, the second rotating shaft 1640 and the second sleeve 1644 can rotate relatively only when an external force is applied to the second rotating shaft 1640 or the second sleeve 1644. When the applied force is removed, the second shaft 1640 and the second sleeve 1644 remain relatively stationary. The second rotating shaft 1640 and the second sleeve 1644 are in friction fit to generate damping, and a separate damping piece is not needed, so that the structure is simple, the reliability is high, and the cost is low. Referring to fig. 9, the second rotation shaft 1640 includes a second shaft portion 16400 connected to the second mating portion 1642 and a second protruding shaft 16402 extending from a side of the second shaft portion 16400 away from the second mating portion 1642 to a direction away from the second mating portion 1642, wherein the second protruding shaft 16402 is coaxial with the second sleeve 1644. The second protruding shaft portion 16402 has a smaller radius than the second shaft portion 16400, so that a second step (not shown) is formed between the second shaft portion 16400 and the second protruding shaft portion 16402, and the second sleeve 1644 abuts against the second step. The second step includes a surface of the second shaft portion 16400 mating with the second boss 1644 and an outer side surface of the second protruding shaft 16402. The outer surface of the second protruding shaft 16402 is in friction fit with the inner surface of the second sleeve 1644, and the second sleeve 1644 and the second protruding shaft 16402 can rotate relatively only when an external force is applied to the second rotating shaft 1640 or the second sleeve 1644. Preferably, the surface of the second shaft portion 16400 which is engaged with the second sleeve 1644 is also in friction engagement with the inner sidewall of the second sleeve 1644, so that the rotational damping between the second rotating shaft 1640 and the second sleeve 1644 can be further increased.

The second fixing member 1646 is fixed to one side of the second boss 1644. In this embodiment, the second fixing member 1646 extends from one side of the second sleeve 1644 in a direction substantially perpendicular to the second sleeve 1644. In this embodiment, an opening is formed in a sidewall of the second sleeve 1644, and the second fixing member 1646 is inserted into the opening and is fastened to the second sleeve 1644 by a fixing device such as a screw.

The second fixing member 1646 is fixedly connected to the body 10 by a fixing means such as a screw passing through the second fixing hole 16462. It is understood that the fixing manner of the second fixing member 1646 and the main body 10 is not limited to the fixing manner of the second fixing hole 16462 and the fixing device, and may be any suitable fixing manner, such as screwing, interference fit, snap fit, etc., as long as the second fixing member 1646 and the main body 10 can be fixedly connected.

The first and second

rotating shaft assemblies

162 and 164 may be located on the same side of the supporting arm 160, or the first and second

rotating shaft assemblies

162 and 164 may be located on two opposite sides of the supporting arm 160. The first shaft 1620 of the first shaft assembly 162 and the second shaft 1640 of the second shaft assembly 164 may be disposed substantially perpendicular to the first support arm 160, or the first shaft 1620 of the first shaft assembly 162 and the second shaft 1640 of the second shaft assembly 164 may be disposed substantially parallel to the first support arm 160. Specifically, in the illustrated embodiment, the first rotating shaft assembly 162 and the second rotating shaft assembly 164 may be located on the same side of the supporting arm 160, so that the force applied to the rotating connecting mechanism 160 in the direction perpendicular to the supporting arm 160 is balanced, the rotating connecting mechanism 160 rotates more smoothly, and the service life of the rotating connecting mechanism 16 can be prolonged; the first rotating shaft 1620 of the first rotating shaft assembly 162 and the second rotating shaft 1640 of the second rotating shaft assembly 164 are substantially parallel to each other, so that the force applied to the rotating connecting mechanism 160 in a direction parallel to the support arm 160 is balanced, the rotating connecting mechanism 160 rotates smoothly, and the service life of the rotating connecting mechanism 16 can be prolonged.

It is understood that the shapes of the first fixing piece 1626 and the second fixing piece 1646 may be adaptively changed according to the shape of the body 10, so as to facilitate the first fixing piece 1626 and the second fixing piece 1646 to be stably fixed to the body 10.

It is understood that the rotating shaft matching structure between the first rotating shaft 1620 and the first sleeve 1624 and between the second rotating shaft 1640 and the second sleeve 1644 are not limited to the above-mentioned embodiments, and may be other suitable structures. For example, the first/second shaft sleeves may extend out of the rotating shaft, and the corresponding first/second rotating shaft extends out of the shaft sleeve and is sleeved on the rotating shaft. Alternatively, in other embodiments, the first/second rotating shaft is omitted, the rotating shaft is fixed on the arm main body 1600 of the arm 160, and the first/second bushing is sleeved on the rotating shaft. The rotating connection between the rotating shaft and the shaft sleeve is friction fit.

When the clamping device 15 is assembled to the body 10, the first rotating shaft assembly 162 and the second rotating shaft assembly 164 are assembled to the arm main body 1600, respectively, so as to complete the assembly of the rotating connecting mechanism 16. Securing the first mount 1626 of the rotating coupling mechanism 16 to the body 10 then completes the secure mating of the rotating coupling mechanism 16 to the body 10. Finally, the second securing member 1646 is secured to the clamping portion 18 such that the clamping portion 18 is rotationally secured to the free end of the rotating connection 16.

Referring to fig. 10, when the rotating connection mechanism 16 is assembled to the body 10, an external force is applied to the rotating connection mechanism 16, and the rotating connection mechanism 16 can rotate relative to the body 10. When the external force applied to the rotational connection mechanism 16 is removed, the rotational damping between the first shaft 1620 and the first sleeve 1624 keeps the first shaft 1620 and the first sleeve 1624 relatively stationary, so that the arm main body 1600 fixedly connected to the first shaft 1620 is kept stationary relative to the body 10 fixedly connected to the first sleeve 1624.

When the electronic device 2 is clamped, an external force is applied to the rotating connection mechanism 16 to make the free end of the rotating connection mechanism 16 rotate towards a direction away from the body 10, until the distance between the free ends of the two rotating connection mechanisms 16 is greater than the width or length of the electronic device, the two ends of the electronic device 2 are abutted against the clamping grooves 180 of the clamping portions 18 connected with the free ends of the two rotating connection mechanisms 16, and then the external force is applied to the rotating connection mechanism 16 to make the free ends of the rotating connection mechanisms 16 rotate towards the body 10 until the two opposite sides of the electronic device 2 are abutted against the corresponding clamping grooves 180 respectively. At this time, the external force applied to the rotating connection mechanisms 16 is removed, the rotating connection mechanisms 16 are stationary relative to the main body 10, and the electronic device 2 is clamped in the clamping groove 180. The anti-slip structure is disposed in the clamping groove 180, so that the electronic device 2 can be further prevented from falling off from the clamping groove 180.

When the electronic device 2 is not required to be clamped, the clamping device 15 can be folded relative to the body 10. Firstly, the two rotary connecting mechanisms 16 are rotated to enable the rotary connecting mechanisms 16 to be close to the machine body 10, and then the clamping part 18 is rotated relative to the rotary connecting mechanisms 16, so that the clamping groove 180 of the clamping part is clamped at the edge of the machine body, and the folding of the clamping device 15 is completed.

Since the rotating link mechanism 16 can rotate to any position between the unfolded position and the folded position relative to the main body and can be kept stationary relative to the main body 10 at the any position, various electronic devices with different sizes can be clamped. The adjustable clamping range is large, and the clamping force is reliable. The clamping device is simple in structure, can be folded and is convenient to carry.

In addition, it is obvious to those skilled in the art that other various corresponding changes and modifications can be made according to the technical idea of the present invention, and all such changes and modifications should fall within the scope of the claims of the present invention.
