All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, in a first aspect, an embodiment of the present invention provides a damping mechanism 100, including: a base 110, the base 110 having a limiting groove 111;
a damping shaft 120 penetrating the limiting groove 111;
a synchronizing connection plate 130 fixed to one end of the damping shaft 120 for providing a rotational force to the damping shaft 120;
a sliding block 150 capable of moving along the axial line direction of the damping shaft 120 and rotatably sleeved on the damping shaft 120 along with the damping shaft 120; the sliding block 150 abuts against the inner wall of the limiting groove 111, and as shown in fig. 1, the base 110 has a boss 140 on one side of the limiting groove 111 facing the sliding block 150. The contact surfaces of the sliding block 150 and the inner wall of the limit groove 111 are respectively provided with damping teeth 160, which are equivalent to the damping teeth 160 formed by the lug boss 140; when the damping shaft 120 rotates, the tooth peaks of the bosses 140 contact the tooth peaks of the sliding blocks 150, or the tooth valleys of the bosses 140 contact the tooth peaks of the sliding blocks 150;
the elastic piece 170 is arranged in the limiting groove 111 and is abutted with one end of the sliding block 150, which is far away from the inner wall of the sliding groove, and the elastic piece 170 is in a compressed energy storage state so that the damping teeth 160 of the sliding block 150 are abutted with the damping teeth 160 of the boss 140.
The damping mechanism 100 provided by the invention comprises a base 110, wherein the base 110 is provided with a limiting groove 111, the limiting groove 111 is provided with a damping shaft 120 in a penetrating way, one end of the damping shaft 120 is fixed with a synchronous connecting plate 130, and the synchronous connecting plate 130 provides a rotating force for the damping shaft 120, so that the damping shaft 120 can rotate relative to the base 110. The damping shaft 120 is sleeved with a damping sliding block 150, the limiting groove 111 is provided with an elastic piece 170, and the elastic piece 170 is abutted between the sliding block 150 and the inner wall of one side of the limiting groove 111, so that the sliding block 150 is always abutted against the inner wall of one side of the limiting groove 111 close to the synchronous connecting plate 130. It should be noted that the elastic member 170 is always in the energy storage state to provide the pressing force to the sliding block 150. Damping teeth 160 are provided between the contact surfaces of the boss 140 and the slider 150. When the damping shaft 120 rotates, the sliding block 150 rotates along with the damping shaft 120, and the tooth peaks of the sliding block 150 are in contact with the tooth peaks of the boss 140; when the sliding block 150 continues to rotate to a certain position with the damping shaft 120, the valleys of the sliding block 150 contact the peaks of the protrusions 140. In the above-described rotation process, the state of the damping teeth 160 between the slide block 150 and the boss 140 changes from the peak-to-peak state to the valley-to-peak state between the slide block 150 and the base 110, and in this change process, the slide block 150 moves relative to the stopper groove 111 along the axial line direction of the damping shaft 120. In other words, when the synchronous connecting plate 130 rotates the damping shaft 120, the sliding block 150 slides relative to the damping shaft 120 while rotating with the damping shaft 120. The damping mechanism 100 provided by the invention specifically works as follows: when the synchronous connecting plate 130 rotates, the synchronous connecting plate 130 drives the damping shaft 120 and the sliding block 150 to rotate together, at this time, the damping teeth 160 of the sliding block 150 extrude the damping teeth 160 of the boss 140, and in the process, the damping teeth 160 of the sliding block 150 move in the direction away from the boss 140 along the axis direction of the damping shaft 120 and compress the elastic member 170; when the teeth of the boss 140 contact the teeth of the sliding block 150, the elastic member 170 provides a damping force opposite to the moving direction of the sliding block 150.
The elastic member 170 of the damping mechanism 100 of the present invention provides a damping force to the slider 150. When the damping teeth 160 of the anti-protruding platform 140 and the sliding block 150 are peak-to-peak, a friction force exists between the two, and the damping mechanism 100 provided by the invention can realize the hovering effect of the synchronous connecting plate 130 at any position by using the friction force. Meanwhile, the damping mechanism 100 provided by the invention has a simple structure and is convenient to control.
Specifically, the elastic member 170 may be, for example, a spring or a torsion spring, which can provide a pre-tightening force.
Specifically, the peaks of the damping teeth 160 have plateaus.
Thus, when the damping teeth 160 of the boss 140 and the sliding block 150 are opposite to each other, the sliding block 150 rotates along with the damping shaft 120, and the tooth peaks have platforms, so that the tooth peaks of the boss 140 and the sliding block 150 can be in continuous contact on the platforms for a period of time, so as to ensure that the friction force between the boss 140 and the sliding block 150 is always and continuously, and the friction force between the boss 140 and the sliding block 150 is matched with the pre-tightening force provided by the elastic piece 170 for the sliding block 150, so that the synchronous connecting plate 130 can realize hovering at any position.
For example, the peak-to-peak contact time of the damping teeth 160 of the boss 140 and slider 150 may be controlled by setting the extension length of the platform.
