In the embodiment of the application, the limiting assembly 50 is arranged, so that the difficulty of sliding the swing arm 20 relative to the fixed bracket 30 when the swing arm 20 is in the unfolded state and the folded state is increased, and the stability of the hinge assembly is improved.
It should be noted that the rotation shaft 10, the swing arm 20, the fixing bracket 30, the connection shaft 40 and the limiting assembly 50 may form a swing arm assembly, and the number of swing arm assemblies included in the hinge assembly is not limited herein, alternatively, the number of swing arm assemblies may be two, so that the coverage area of the hinge assembly may be increased.

In the embodiment of the application, since the fixed bracket 30 is provided with the sliding groove 31, and the damping block 51 included in the limiting assembly 50 is positioned between the connecting shaft 40 and the sliding groove 31, the limiting effect on the connecting shaft 40 can be better, and the limiting effect on the swing arm 20 is further enhanced.
In addition, when the swing arm 20 is in the folded state, the end of the connecting shaft 40 is respectively abutted with the side wall (i.e., the first side wall) of the sliding groove 31 close to the rotating shaft 10 and the end (i.e., the first end) of the damping block 51 close to the rotating shaft 10, so that the side wall (i.e., the first side wall) of the sliding groove 31 close to the rotating shaft 10 and the end (i.e., the first end) of the damping block 51 close to the rotating shaft 10 both have acting forces on the end of the connecting shaft 40, and under the acting forces, the limiting effect on the connecting shaft 40 can be further enhanced, and the limiting effect on the swing arm 20 is further enhanced.

It should be noted that, only when the swing arm 20 receives the force, so that the swing arm 20 rotates around the rotating shaft 10, and the force on the swing arm 20 is greater than the damping force threshold, the end of the connecting shaft 40 can be driven to move along the extending direction of the chute 31, so that the swing arm 20 is switched between the folded state and the unfolded state. The specific value of the damping force threshold is not limited herein, and may be, for example, a value corresponding to the acting force from at least one of the chute 31 and the damping block 51 to the end of the connecting shaft 40.

The damping block 51 is provided with a protruding portion 52, and the protruding portion 52 may be embedded in the groove 311 and rotate relative to the groove 311 to drive the damping block 51 to rotate relative to the fixed bracket 30, so that the above structure can be understood as a seesaw structure formed by the damping block 51 and the protruding portion 52.
Alternatively, the damper block 51 and the boss 52 may be an integrally formed structure, so that the connection strength between the damper block 51 and the boss 52 may be enhanced.

Similarly, when the swing arm 20 is in the unfolded state, the end of the connecting shaft 40 is respectively abutted with the top wall of the sliding groove 31, the side wall (i.e. the second side wall) of the sliding groove 31 far away from the rotating shaft 10, and the end (i.e. the second end) of the damping block 51 far away from the rotating shaft 10, i.e. the top wall of the sliding groove 31, the side wall (i.e. the second side wall) of the sliding groove 31 far away from the rotating shaft 10, and the end (i.e. the second end) of the damping block 51 far away from the rotating shaft 10 all have acting forces on the end of the connecting shaft 40, so that the limiting effect on the end of the connecting shaft 40 can be further enhanced.
As an alternative embodiment, when the swing arm 20 is in the folded state, an included angle between a surface of the bottom wall of the damping block 51 facing the chute 31 and the bottom wall of the chute 31 is a first included angle, and when the swing arm 20 is in the unfolded state, an included angle between a surface of the bottom wall of the damping block 51 facing the chute 31 and the bottom wall of the chute 31 is a second included angle, and the second included angle is larger than the first included angle.
As shown in fig. 5, the first included angle may be an included angle between the damping block 51 and the bottom wall of the chute 31, as shown in fig. 6, and the second included angle may be an included angle between the damping block 51 and the bottom wall of the chute 31, it is obvious that the second included angle in fig. 6 is larger than the first included angle in fig. 5.

The above-described embodiments may be described more fully with reference to the following description.
Referring to fig. 5, when the swing arm 20 is in the folded state, a distance between an end (i.e., a first end) of the damping block 51, which is close to the rotating shaft 10, and the bottom wall of the chute 31 is smaller than a distance between an end (i.e., a second end) of the damping block 51, which is far from the rotating shaft 10, and the bottom wall of the chute 31;
Referring to fig. 6, when the swing arm 20 is in the extended state, the distance between the end (i.e., the first end) of the damping block 51, which is close to the rotating shaft 10, and the bottom wall of the sliding slot 31 is greater than the distance between the end (i.e., the second end) of the damping block 51, which is far from the rotating shaft 10, and the bottom wall of the sliding slot 31.
In the embodiment of the application, since the damping block 51 and the boss 52 may form a teeterboard structure, when the swing arm 20 is in the folded state, the distance between the end of the damping block 51 close to the rotating shaft 10 and the bottom wall of the sliding groove 31 is smaller than the distance between the end of the damping block 51 far from the rotating shaft 10 and the bottom wall of the sliding groove 31, i.e. the height of the end of the damping block 51 close to the rotating shaft 10 in the sliding groove 31 is lower than the height of the end of the damping block 51 far from the rotating shaft 10 in the sliding groove 31, the end of the damping block 51 far from the rotating shaft 10 is raised, and the end of the damping block 51 close to the rotating shaft 10 is lowered, i.e. the surface of the damping block 51 facing the bottom wall of the sliding groove 31 is an inclined surface with gradually increased height along the direction from the end of the damping block 51 close to the rotating shaft 10 to the end of the damping block 51 far from the rotating shaft 10, thereby further increasing the difficulty of sliding the end of the connecting shaft 40 toward the sliding groove 31 in the side wall direction far from the rotating shaft 10, further increasing the stability between the end of the connecting shaft 40 and the sliding groove 31 and the damping block 51.
Alternatively, referring to fig. 5, when the swing arm 20 is in the folded state, the end of the connecting shaft 40 is left of the damping block 51, the damping block 51 is in a pre-pressed state under the pressure of the end of the connecting shaft 40, the contact surface between the damping block 51 and the end of the connecting shaft 40 is low left and high right, the end of the connecting shaft 40 is stressed to move leftwards, and meanwhile, if the end of the connecting shaft 40 moves rightwards, a certain power is required to be provided, so that the end of the connecting shaft 40 cannot slide freely in the chute 31, thereby increasing the stability of connection.
When the swing arm 20 is switched from the unfolded state to the folded state, that is, when the external force is greater than the damping force threshold, the swing arm 20 drives the end part of the connecting shaft 40 to move in the chute 31, and finally the swing arm 20 can move to the position shown in fig. 6, and in the process that the swing arm 20 drives the end part of the connecting shaft 40 to move in the chute 31, the top wall of the chute 31 can always provide a pressing force for the end part of the connecting shaft 40, so that the end part of the connecting shaft 40 and the chute 31 are always in a zero clearance state.
Meanwhile, when the swing arm 20 is in the unfolded state, the distance between the end of the damping block 51, which is close to the rotating shaft 10, and the bottom wall of the sliding groove 31 is larger than the distance between the end of the damping block 51, which is far away from the rotating shaft 10, and the bottom wall of the sliding groove 31, namely, the height of the end of the damping block 51, which is close to the rotating shaft 10, in the sliding groove 31 is higher than the height of the end of the damping block 51, which is far away from the rotating shaft 10, in the position of the sliding groove 31, and the end of the damping block 51, which is far away from the rotating shaft 10, is tilted, namely, the surface of the bottom wall of the damping block 51, which faces the sliding groove 31, is the inclined surface with gradually increased height along the direction from the end of the damping block 51, which is far away from the rotating shaft 10, to the end of the damping block 51, which is close to the rotating shaft 10, is located towards the side wall of the sliding groove 31, which is close to the rotating shaft 10, of the end of the connecting shaft 40 is further increased, and the stability between the end of the connecting shaft 40 and the sliding groove 31 and the damping block 51 is further enhanced.
Optionally, referring to fig. 6, when the swing arm 20 is in the unfolded state, the end of the connecting shaft 40 is located on the right side of the damping block 51, the damping block 51 is in a pre-pressed state under the pressure of the end of the connecting shaft 40, the contact surface between the damping block 51 and the end of the connecting shaft 40 is high and low in the left-right direction, a large inclined surface state is formed, the end of the connecting shaft 40 is stressed and has a right movement trend, meanwhile, if the end of the connecting shaft 40 moves leftwards, a certain power is required to be provided, the end of the connecting shaft 40 cannot slide freely, and meanwhile, unfolding maintaining force can be provided for the hinge assembly, so that the end of the connecting shaft 40 cannot slide freely in the chute 31, and the stability of connection is improved.
When the swing arm 20 is switched from the unfolded state to the folded state, that is, when the external force is greater than the damping force threshold, the swing arm 20 drives the end part of the connecting shaft 40 to move in the chute 31, and finally the swing arm 20 can move to the position shown in fig. 5, and in the process that the swing arm 20 drives the end part of the connecting shaft 40 to move in the chute 31, the top wall of the chute 31 can always provide a pressing force for the end part of the connecting shaft 40, so that the end part of the connecting shaft 40 and the chute 31 are always in a zero clearance state.
As an alternative embodiment, referring to fig. 4 to 6, the protrusion 52 is located on a surface of the damping block 51 facing the bottom wall of the chute 31, and the protrusion 52 is disposed close to a side wall of the chute 31 remote from the rotation shaft 10.
In the embodiment of the application, the boss 52 is not arranged at the middle position of the surface of the damping block 51 facing the bottom wall of the chute 31, but is arranged at the position close to the side wall of the chute 31 away from the rotating shaft 10, so that the damping force required to be opposed by the swing arm 20 in the unfolded state is smaller than the damping force required to be opposed by the swing arm 20 in the folded state, thereby being capable of facilitating the switching of the swing arm 20 from the unfolded state to the folded state, i.e. being capable of facilitating the folding of the swing arm 20.
As an alternative embodiment, referring to fig. 5, the fixing bracket 30 includes a bracket body 32 and a pressing piece 33, the bracket body 32 and the pressing piece 33 are connected, and the bracket body 32 and the pressing piece 33 enclose the sliding slot 31.
