[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] This utility model proposes a damping mechanism that can realize the dual functions of manual rotation and electric rotation. Figures 1 to 4 The damping mechanism 100 includes a motor 101, a gear assembly 102 and a housing 103 for accommodating the gear assembly 102; the housing 103 has a groove I 1031.

[0036] The gear assembly 102 includes a gear I11 , a gear II12 meshing with the gear I11 , a damping plate 13 disposed in a slot 121 of the gear II12 , and a rotating shaft I14 matching the damping plate 13 .

[0037] Gear I11 is connected to the output shaft of the motor. The number of teeth of gear I11 is smaller than the number of teeth of gear II12, that is, gear I11 and gear II12 form a reduction mechanism. The reduction ratio can be set as needed and there is no restriction on this.

[0038] See Figure 2 The gear II 12 has a slot 121 , and a recess 122 is formed along the slot 121 . The slot 121 and the recess 122 are used to accommodate the damping plate 13 . The center hole 123 of the gear II 12 is used for the rotation axis I 14 to pass through.

[0039] See Figure 3 The damping plate 13 includes two clamping plates 131, the clamping plate 131 has a clamping portion 1312, the clamping portion 1312 is in surface contact (including line contact) with the rotating axis I14, one end of the clamping portion 1312 is a free end 1311, and the other end of the clamping portion 1312 is a connecting end 1313, which is connected to the bending portion 132.

[0040] The damping plate 13 is made of metal, such as carbon steel, stainless steel, alloy, etc., and has sufficient rigidity and strength. Polymer materials and rubber materials (not shown in the figure) are arranged on the surface of the clamping part 1312 to reduce noise, resist heat and cold, and prevent aging and rust.

[0041] See Figure 4 The rotating shaft I14 includes a body 141, a baffle 142 arranged along the circumference of the body 141, and a female groove 143 arranged at the end of the rotating shaft.

[0042] When assembling the damping mechanism 100, the gear I11 and the gear II12 are meshed with each other and arranged in the housing 103, as shown in FIG. Figure 1 As shown, a motor 101 is set on the bottom surface of the gear I11 (negative direction of the z axis), and the output shaft of the motor 101 passes through the housing 103 and is connected to the gear I11. The motor 101 can be forward and reverse, driving the gear I11 to rotate, and then driving the gear II12 to rotate; the damping plate 13 is installed on the rotating shaft I14, combined with Figure 3 and Figure 4 , open the clamping piece 131, place the body 141 of the rotating shaft I14 on the clamping part 1312, the clamping part 1312 is in surface contact with the body 141 of the rotating shaft I14, and keep the clamping piece 131 in contact with the baffle 142 of the rotating shaft I14 to prevent the damping plate 13 from escaping from the slot 121, and then install the assembled damping plate 13 and rotating shaft I14 on the gear II 12, that is, the body 141 of the rotating shaft I14 is inserted into the center hole 123 of the gear II 12, and the free end 1311 of the damping plate 13 is clamped in the slot 121 of the gear II 12; when the gear II 12 rotates, under the action of the friction resistance generated by the damping plate 13 on the rotating shaft II 12, the rotating shaft I14 rotates with the gear II 12, realizing electric rotation; when manually rotated, the friction between the clamping part 1312 of the damping plate 13 and the rotating shaft I14 is overcome, and the rotating shaft I14 can be manually rotated.

[0043] This application proposes a flip camera with the damping mechanism, see Figures 5 to 7The flip camera includes a camera body 200, on which a lens 201, a flip cover 202, and a bracket 203 are mounted. The flip cover 202 is provided with a support foot. By rotating about the support foot, the flip cover 202 can flip open and close the lens 201 on the camera body 200 to protect the lens 201. The bracket 203 is used to secure the camera body 200.

[0044] The end of the rotating shaft I14 of the damping mechanism 100 is connected to the rotating shaft II104. The damping mechanism 100 is disposed within the camera body 200. The rotating shaft II104 extends out of the camera body 200 and is connected to the legs of the flip cover 202, such as by snapping, riveting, or mechanical locking. Driven by the motor 101, the rotating shaft II104 rotates, thereby rotating the flip cover 202. Furthermore, since the rotation is achieved by the friction of the damping plate 13 within the damping structure 100 on the rotating shaft I14, manual adjustment is possible to any angle by overcoming the friction of the damping plate 13 on the rotating shaft I14, meeting personalized settings.

[0045] It can be seen that the damping mechanism 100 can be applied to fields that need to be covered and frequently adjusted, such as curtains, window screens, curtains, bed curtains, and fields of rotation such as oscillating fans, oscillating selfie sticks, and rotating displays.

[0046] It is known that a micro switch can be provided on the damping mechanism 100 to limit the adjustment angle during electric adjustment, such as Figure 1 Two micro switches are set on the bottom surface (negative direction of z axis) of gear II 12 (housing 103). After gear II 12 rotates a certain angle, the micro switch is triggered to control the motor 101 to stop working or reverse.

[0047] It is known that a control unit may be provided on the damping mechanism 100 . The control unit is electrically connected to the motor 101 and the micro switch. The control unit controls the motor 101 of the damping mechanism 100 to achieve fixed angle rotation.

[0048] It is known that the control unit on the damping mechanism 100 can also be provided with a wireless transmission unit to realize remote control, such as control through a mobile terminal (mobile phone, iPad, remote control, computer).
