In addition, in the embodiment of the present application, as shown in fig. 7, the spindle mechanism 100 may further include: at least one stopper 130, the stopper 130 reciprocates in the sliding groove 1212 along the circumferential direction of the catching assembly 120, and a first width W1 (see fig. 10) of the sliding groove 1212 becomes gradually smaller or gradually larger along the circumferential direction of the catching assembly 120.
In this embodiment, the first width W1 may be a dimension of the sliding groove 1212 in a radial direction of the engaging assembly 120.
By providing the opening 1211 on the engaging component 120, at least a portion of the mandrel component 110 is disposed through the opening 1211, and at least one sliding slot 1212 communicating with the opening 1211 is further disposed on the engaging component 120, when the mandrel component 110 rotates relative to the engaging component 120, i.e. the mandrel component 110 rotates in the opening 1211 of the engaging component 120, the blocking member 130 is driven to reciprocate in the sliding slot 1212 along the circumferential direction of the engaging component 120.
Since the dimension of the sliding groove 1212 in the radial direction of the engaging component 120 is gradually smaller or larger along the circumferential direction of the engaging component 120, when the spindle component 110 rotates in the clockwise direction in the opening 1211 of the engaging component 120 and drives the blocking member 130 to reciprocate in the sliding groove 1212 along the circumferential direction of the engaging component 120, the blocking member 130 can realize regular and rapid switching of the interference magnitude in the reciprocating process.
Thus, the damping force generated by the spindle assembly 110 and the engaging assembly 120 is gradually increased or gradually decreased, and when the spindle assembly 110 rotates in the counterclockwise direction in the opening 1211 of the engaging assembly 120 and drives the stopper 130 to reciprocate in the sliding groove 1212 along the circumferential direction of the engaging assembly 120, the damping force generated by the spindle assembly 110 and the engaging assembly 120 is opposite to that, i.e., the damping force generated by the spindle assembly 110 and the engaging assembly 120 is gradually decreased or gradually increased.
That is, when the spindle assembly 110 rotates relative to the clamping assembly 120, the damping force generated by the spindle mechanism 100 can be changed according to the requirements of the actual application scene, which is beneficial to the opening and closing experience of the foldable electronic device, so as to satisfy the use requirements of the user in more application scenes, and further improve the usability of the electronic device. Moreover, the rotating shaft mechanism 100 provided by the embodiment of the application is simple in structure, convenient to work and high in practicability.
For example, taking the notebook computer 300 as an example, when the display 310 and the host body 320 relatively rotate through the hinge mechanism 100, the damping force of the hinge mechanism 100 may be set to be gradually reduced during the process of opening relative to the host body 320, specifically, the dimension of the sliding slot 1212 in the hinge mechanism 100 in the radial direction of the engaging component 120 may be designed to be gradually increased along the direction of opening the notebook computer 300, so that the spindle component 110 rotates in the opening 1211 of the engaging component 120 along the direction of opening the notebook computer 300, and drives the blocking member 130 to move along the circumferential direction of the engaging component 120 from the narrow end to the wide end in the sliding slot 1212, that is, when the blocking member 130 moves along the direction of gradually increasing the first width W1 in the sliding slot 1212, the interference between the spindle component 110 and the engaging component 120 is gradually reduced, so that the damping force generated by the spindle component 110 and the engaging component 120 is gradually reduced.
Also, the display 310 may set the damping force of the hinge mechanism 100 to gradually increase during the closing process with respect to the main body 320, specifically, the size of the sliding groove 1212 of the hinge mechanism 100 in the radial direction of the clamping assembly 120 may be designed to gradually decrease in the closing direction of the notebook computer 300, so that the spindle assembly 110 rotates in the opening 1211 of the clamping assembly 120 in the closing direction of the notebook computer 300, and drives the blocking member 130 to move from the wide end to the narrow end in the circumferential direction of the clamping assembly 120 in the sliding groove 1212, that is, the interference amount between the spindle assembly 110 and the clamping assembly 120 gradually increases when the blocking member 130 moves in the gradually decreasing direction along the first width W1 in the sliding groove 1212, thereby gradually increasing the damping force generated by the spindle assembly 110 and the clamping assembly 120.
In this way, the damping force of the rotating shaft mechanism 100 is smaller in the process of opening the display 310 relative to the host body 320, and the damping force of the rotating shaft mechanism 100 is larger in the process of closing the display 310 relative to the host body 320, that is, the damping force of the rotating shaft mechanism 100 when opening is smaller than the damping force when closing, so that the ideal opening and closing experience of the notebook computer 300 when opening and closing lightly can be realized. Compared with the prior art, the damping force of the rotating mechanism 100 is constant in the whole opening or closing process of the notebook computer 300, namely the opening force and the closing force of the notebook computer 300 in the prior art are equal, the damping force can be changed according to the requirements of practical application scenes, and the folding electronic equipment opening and closing experience is facilitated.
With continued reference to fig. 6, in the embodiment of the present application, the engaging component 120 may further be provided with a slit 1213, where the slit 1213 is opened along the radial direction of the engaging component 120. The slit 1213 may be offset from the slide groove 1212, and the slit 1213 communicates with the opening 1211.
By providing the slots 1213 in the radial direction on the engaging component 120, and the slots 1213 are communicated with the openings 1211, when the spindle component 110 rotates in the openings 1211 of the engaging component 120, the slots 1213 can provide redundant space for the rotation of the spindle component 110, so that the spindle component 110 and the engaging component 120 are prevented from being worn by the rotation of the spindle component 110 in the openings 1211 of the engaging component 120, and the reliability and the service life of the spindle mechanism 100 are affected.
As shown in fig. 7, in the embodiment of the present application, the spindle mechanism 100 may further include: at least one elastic member 140, wherein one end of the elastic member 140 is fixedly connected with the inner wall of the sliding groove 1212, and the other end of the elastic member 140 abuts against the blocking member 130.
By arranging at least one elastic member 140 in the rotation shaft mechanism 100, one end of each elastic member 140 is fixedly connected with the inner wall of the sliding groove 1212, the other end of each elastic member 140 is abutted against the blocking member 130, and when the blocking member 130 reciprocates in the sliding groove 1212 along the circumferential direction of the clamping assembly 120, the blocking member 130 presses the elastic member 140 to a compressed state toward the inner wall of the sliding groove 1212 in a certain direction, and then the elastic restoring force of the elastic member 140 can provide power for the blocking member 130 to move in the opposite direction.
It is understood that in the embodiment of the present application, the number of the elastic members 140 may be one, two or more in the same sliding groove 1212. Taking the number of the elastic members 140 as one example, one end of the elastic member 140 is fixedly connected with any one inner wall of the sliding groove 1212, and the other end of the elastic member 140 abuts against the blocking member 130. Taking the number of the elastic pieces 140 as two as an example, one end of one elastic piece 140 is fixedly connected with one inner wall of the sliding groove 1212, the other end of the elastic piece 140 is abutted against the blocking piece 130, one end of the other elastic piece 140 is fixedly connected with the other inner wall of the sliding groove 1212, and the other end of the elastic piece 140 is abutted against the blocking piece 130.
In one possible implementation, when the number of the elastic members 140 is two, the two elastic members 140 are fixedly connected to the two inner walls of the sliding groove 1212, respectively, the two inner walls may be disposed opposite to each other.
In this way, when one of the elastic members 140 is pressed to a compressed state toward the inner wall of the sliding groove 1212 by the blocking member 130 in a certain direction, the other elastic member 140 is also adjusted to an extended state, and at this time, the elastic restoring force of the elastic member 140 and the elastic restoring force of the other elastic member can both provide power for the movement of the blocking member 130 in opposite directions.
In addition, in the embodiment of the present application, the elastic member 140 may be generally pressed against the elastic member, and when the blocking member 130 presses the elastic member 140 toward the inner wall of the sliding groove 1212 in a certain direction, the elastic member 140 is in a compressed state. Thus, the elastic member 140 can generate an elastic force in the opposite direction to restore the blocking member 130 to the initial position. Specifically, the elastic member 140 may be a compression spring in general.
In this embodiment, the number of the sliding grooves 1212 may be plural, and the plurality of sliding grooves 1212 may be distributed on the engaging assembly 120 at intervals along the circumferential direction of the engaging assembly 120.
Through designing the number of sliding grooves 1212 into a plurality of, and a plurality of sliding grooves 1212 are distributed on the clamping assembly 120 along the circumferential direction of the clamping assembly 120 at intervals, the fit smoothness and stability between the mandrel assembly 110 and the clamping assembly 120 can be increased, i.e. the working smoothness and stability of the spindle mechanism 100 can be increased.
Illustratively, in fig. 6, the number of sliding grooves 1212 may be three, and the three sliding grooves 1212 may be distributed on the snap assembly 120 at intervals along the circumferential direction of the snap assembly 120.
Of course, in some embodiments, the number of the sliding grooves 1212 may be one, two, four or more, which is not limited in the embodiments of the present application.
In addition, the number of the blocking members 130 can be flexibly set according to the requirements of the actual application scenario. Taking the example of three sliding slots 1212 in fig. 6, the number of stops 130 may be three, and each sliding slot 1212 may have one stop 130 therein. Alternatively, the number of the stoppers 130 may be two, and one stopper 130 may be provided in each of two sliding grooves 1212 of the three sliding grooves 1212, and the other sliding groove 1212 may be provided without the stopper 130. Alternatively, the number of the blocking members 130 may be one, one blocking member 130 may be provided in one sliding groove 1212 of the three sliding grooves 1212, and the blocking members 130 may not be provided in the other two sliding grooves 1212.
It will be appreciated that the first width W1 (see fig. 10) of the sliding groove 1212 may be gradually smaller or larger along the circumferential direction of the snap assembly 120, that is, the sliding groove 1212 may be designed as a unidirectional horn shape, the spindle assembly 110 may drive the stopper 130 to roll due to interference when the spindle assembly 110 rotates, and further, since the sliding groove 1212 is unidirectional horn shape and the length of the sliding groove 1212 is limited, when the stopper 130 rolls to one end of the sliding groove 1212 along the extending direction of the sliding groove 1212, the stopper 130 is limited, the spindle assembly 110 continues to rotate, the interference between the spindle assembly 110 and the opening 1211 of the snap assembly 120 is reduced, so that the damping force between the spindle assembly 110 and the snap assembly 120 is reduced. In contrast, when the stopper 130 rolls to the other end of the sliding groove 1212 along the extending direction of the sliding groove 1212, the amount of interference between the spindle assembly 110 and the opening 1211 of the snap assembly 120 increases, so that the damping force between the spindle assembly 110 and the snap assembly 120 increases.

The second fixing portion 122 is fixedly connected to the first portion or the second portion, so that when the engaging component 120 rotates relative to the mandrel component 110, the first portion or the second portion is driven to rotate relative to the mandrel component 110.
It is to be understood that the sliding groove 1212 and the slit 1213 are both formed in the engaging portion 121 of the engaging member 120, the sliding groove 1212 and the slit 1213 are disposed in a staggered manner, and the sliding groove 1212 and the slit 1213 communicate with each other.
