Preferably, a plurality of first concave portions 301 may be provided on each first drive ring 30, the plurality of first concave portions 301 being provided at intervals around the first spindle 10; and when the first support 2 is fully unfolded relative to the second support 3, the first convex part 202 is embedded into one first concave part 301, when the first support 2 is fully folded relative to the second support 3, the first convex part 202 is embedded into the other first concave part 301, so that the first support 2 and the second support 3 can be kept in the unfolded state and the folded state, damping force is provided during the processes of just unfolding and just folding, restoring force is provided when the first support 2 is fully unfolded and just folded, and the first support 2 and the second support 3 are pushed to be fully unfolded and fully folded. In addition, the first driving ring 30 is disposed on both sides of the first connecting portion 20, and compared with the first driving ring 30 disposed on only one side, the amount of deformation of the first spring 40 in the axial direction is increased during the unfolding and folding processes, and the damping force and restoring force are improved, thereby improving the user experience.
Continuing with fig. 1-6. Illustratively, when the first connecting portions 20 and the second connecting portions 60 are gradually folded from the unfolded state with an included angle of 180 °, the first protruding portions 202 on both sides of the first connecting portions 20 gradually slide out of the corresponding first recessed portions 301, and at this time, the first driving ring 30 in contact with the first springs 40 and the first connecting portions 20 are driven to move in the axial direction to compress the first springs 40 to provide a damping force, thereby preventing the first connecting portions 20 and the second connecting portions 60 from being folded; when the first connecting portion 20 and the second connecting portion 60 are folded to form an included angle of 150 °, the first protruding portions 202 on both sides of the first connecting portion 20 completely slide out of the first recessed portion 301; in the process that the included angle between the first connecting part 20 and the second connecting part 60 is between 150 degrees and 30 degrees, the first convex parts 202 on both sides of the first connecting part 20 slide outside the first concave part 301; when the angle between the first connecting portion 20 and the second connecting portion 60 is 30 °, the first protruding portions 202 on both sides of the first connecting portion 20 gradually enter into the corresponding other first recessed portions 301, at this time, the first driving ring 30 in contact with the first springs 40 and the first connecting portion 20 move in the axial direction, and the first springs 40 gradually expand to provide a restoring force, thereby driving the first connecting portion 20 and the second connecting portion 60 to continue to fold until the first connecting portion 20 and the second connecting portion 60 are completely folded. On the contrary, when the included angle between the first connecting portion 20 and the second connecting portion 60 is gradually expanded from 0 °, the first protruding portions 202 on both sides of the first connecting portion 20 gradually slip out of the corresponding first recessed portions 301, and at this time, the first driving ring 30 and the first connecting portion 20 in contact with the first spring 40 are driven to move in the axial direction to compress the first spring 40, providing a damping force, thereby preventing the first connecting portion 20 and the second connecting portion 60 from expanding; when the first connecting part 20 and the second connecting part 6060 are unfolded to form an included angle of 30 degrees, the first protruding parts 202 on both sides of the first connecting part 20 completely slide out of the corresponding first concave parts 301; in the process that the included angle between the first connecting part 20 and the second connecting part 60 is 30-150 degrees, the first convex parts 202 on both sides of the first connecting part 20 slide outside the first concave part 301; when the first connecting portion 20 and the second connecting portion 60 are unfolded until the included angle between the first connecting portion 20 and the second connecting portion 60 is 150 °, the first protruding portions 202 on both sides of the first connecting portion 20 gradually enter into the corresponding other first recessed portion 301, at this time, the first driving ring 30 and the first connecting portion 20 in contact with the first spring 40 move in the axial direction, and the first spring 40 gradually extends to provide a restoring force, so as to drive the first supporting member 2 and the second supporting member 3 to be unfolded continuously until the first supporting member 2 and the second supporting member 3 are completely unfolded.
It should be noted that when the first connecting portion 20 rotates along with the first support 2, the two first driving rings 30 can only move in the axial direction, so that the first connecting portion 20 rotates relative to the two first driving rings 30, and further the first protruding portions 202 on both sides of the first connecting portion 20 are gradually embedded into the corresponding first recessed portions 301, or the first protruding portions 202 on both sides of the first connecting portion 20 gradually slide out from the corresponding first recessed portions 301. In addition, the above-mentioned unfolding and folding processes are only exemplified by the first protruding portion 202 being disposed on the first connecting portion 20, and of course, the first protruding portion 202 may also be disposed on the two first driving rings 30, and correspondingly, the first recessed portions 301 are disposed on both sides of the first connecting portion 20, and the unfolding and folding processes are substantially the same, and will not be described again.
In the folding module 1 provided by this embodiment, the first connecting portion 20 is provided with a first shaft hole, and the first spindle 10 is inserted into the first driving ring 30, the first shaft hole and the first spring 40; the first drive ring 30 is two, and the first connecting portion 20 is located between the two first drive rings 30; a first convex part 202 and a first concave part 301 are arranged between the first driving ring 30 and the first connecting part 20, and the first spring 40 is pressed against the first driving ring 30, so that the first convex part 202 is embedded into the first concave part 301; during folding or unfolding, the first protrusion 202 slides out of the first recess 301 to provide a damping force for unfolding or folding; compared with the rotation of the first drive ring 30 by the cooperation of the first drive surface on the rotation shaft and the second drive surface on the first drive ring 30, the first connection portion 20 can directly drive the first protrusion 202 and the first recess 301 to move relatively, and the transmission precision is improved.
With continued reference to fig. 1. The folding module 1 provided in this embodiment further includes: a second connecting portion 60, a second spindle 50, a second drive ring 70, and a second spring 80; the second connecting part 60 is provided with a second shaft hole, the second spindle 50 is arranged in the second driving ring 70, the second shaft hole and the second spring 80 in a penetrating way, the number of the second driving rings 70 is two, and the second connecting part 60 is arranged between the two second driving rings 70; a second convex portion 602 and a second concave portion 701 are arranged between the second driving ring 70 and the second connecting portion 60, the second convex portion 602 is located between the second spring 80 and the second concave portion 701, or the second concave portion 701 is located between the second spring 80 and the second convex portion 602, and the second convex portion 602 is embedded in the second concave portion 701; the first mandrel 10 and the second mandrel 50 are arranged in parallel and at intervals, a first tooth-shaped structure 203 is arranged on the first connecting part 20, a second tooth-shaped structure 603 is arranged on the second connecting part 60, and the first tooth-shaped structure 203 is meshed with the second tooth-shaped structure 603; when the second connecting portion 60 rotates, the second protrusion 602 slides out of the second recess 701. With such an arrangement, the second connecting portion 60 can be driven to rotate while the first connecting portion 20 is rotated, and the angles of rotation between the first connecting portion 20 and the second connecting portion 60 are the same; the second connecting portion 60 and the first connecting portion 20 are simultaneously rotated, compared with the case where only the first connecting portion 20 is rotated, so that the time required for rotating to the folded state or the unfolded state can be shortened, and rapid folding and unfolding can be realized. In addition, since the first driving ring 30 and the first connecting portion 10 can rotate relative to the first spindle 10, the first spindle 10 only needs to be inserted into the first driving ring 30 and the first spindle hole when being installed, and the relative positions of the first driving ring 30 and the first connecting portion 10 with the first spindle 10 do not need to be controlled, so that the installation is convenient; similarly, since the second driving ring 70 and the second connecting portion 60 can rotate relative to the second spindle 50, the second spindle 50 only needs to be inserted into the second driving ring 70 and the second spindle hole during installation, and the relative positions of the second driving ring 70 and the second connecting portion 60 with the second spindle 50 do not need to be controlled, which is convenient for installation.
In this embodiment, the connection manner between the second connection portion 60 and the second support 3 may be various, as long as the smooth rotation between the first support 2 and the second support 3 can be ensured; for example: a second sliding column 601 is arranged on the second connecting part 60, a second sliding groove matched with the second sliding column 601 is correspondingly arranged on the second supporting part 3, when the supporting part and the second supporting part 3 rotate relatively, the second connecting part 60 rotates around the second spindle 50, and the second sliding column 601 slides in the second sliding groove. With such an arrangement, when the second connecting portion 60 rotates along with the second supporting member 3, a margin is also left for the sliding of the second connecting portion 60 relative to the second supporting member 3, so that the rotation is smooth.
Further, two second sliding columns 601 are arranged on the second connecting portion 60, and center lines of the two second sliding columns 601 are arranged in a collinear manner; moreover, the two second sliding columns 601 are arranged at two sides of the second connecting portion 60 at intervals, correspondingly, the second support member 3 is provided with two second sliding chutes, each second sliding column 601 is slidably arranged in one second sliding chute, and the second connecting portion 60 is clamped between the two second sliding chutes, so that the second sliding columns 601 can be prevented from being separated from the corresponding second sliding chutes, and the connection stability between the second connecting portion 60 and the second support member 3 is improved.
In this embodiment, the second spring 80 may be a coil spring, the second spindle 50 is inserted into the second shaft hole, the second spring 80 and the two second driving rings 70, and the second spring 80 abuts against one second driving ring 70, so that the two second driving rings 70 clamp the second connecting portion 60; thereby causing the second convex portion 602 between the second drive ring 70 and the second connecting portion 60 to be fitted into the second concave portion 701.
