Referring to FIGS. 7 and 8, FIG. 7 shows an exploded view of the first resilient component and slider; fig. 8 shows a partial cross-sectional view of the first elastic assembly.

The first elastic assembly 210 includes an adaptor 213, a spring 212, and a spring holder 211, and the adaptor 213, the spring 212, and the spring holder 211 are aligned along a third axis. The adaptor 213 is located at a first end of the first elastic member 210 and is adapted to be rotatably coupled with the first synchronization lever 310. A spring holder 211 is located at a second end of the first resilient member 210 and is adapted for rotational attachment to the slider 220. The spring 212 is located between the adapter 213 and the spring holder 211 and is compressed by the spring holder 211 and the adapter 213.

The spring frame 211 comprises a body and a guide post 2111 arranged on the body, the length direction of the body is along the first axial direction, and the body is rotatably connected with the slider 220 through a second rotating shaft. The length direction of the guide post 2111 is along a second direction (the second direction is perpendicular to the rotation axis of the elastic component relative to the slider 330, and can also be understood as perpendicular to the first axis), a through hole 2132 for sliding fitting of the guide post 2111 is arranged in the adaptor 213, and the sliding connection between the adaptor 213 and the spring holder 211 is realized through the matching of the guide post 2111 and the through hole 2132.

The spring 212 is located between the spring frame 211 and the adaptor 213, and two ends of the spring 212 respectively press against the spring frame 211 and the adaptor 213. Illustratively, the spring 212 is sleeved on the guide post 2111, one end of the spring 212 is pressed against the body of the spring holder 211, and the other end is pressed against the adaptor 213.

When the adaptor 213 slides relative to the spring holder 211, the adaptor 213 can slide relative to the spring holder 211, when the adaptor 213 slides toward a direction close to the spring holder 211, the spring 212 is compressed by the adaptor 213 to generate elastic deformation, and when the adaptor 213 slides toward a direction away from the spring holder 211, the elastic deformation of the spring 212 pushes the adaptor 213 to move.

As an alternative, the number of the guide posts 2111 may be multiple, and the plurality of guide posts 2111 are arranged along the first axis, the number of the corresponding springs 212 is also multiple, and the plurality of springs 212 are arranged along the first axis. In fig. 7, four springs 212 are shown, but the number of the springs 212 is not particularly limited in the embodiment of the present application, and the number of the springs 212 in the first elastic member 210 may be one, two, three, etc., and the number of the springs 212 is plural, and the plurality of springs 212 are arranged in a third direction parallel to the first axis of the bracket.

As an alternative, the adaptor 213 is a U-shaped structure, the open side of the U-shaped structure faces the spring holder 211, the through hole 2132 matched with the guide post 2111 is arranged at the horizontal part of the U-shaped structure, and the two side walls are bent to be rotatably connected with the first synchronization rod 310. The side walls bent at the two sides are provided with long waist holes 2131, the first synchronization rod 310 is provided with a third rotating shaft which is inserted into the long waist holes 2131 and can slide and rotate in the long waist holes 2131, and the connection of the adapter 213 and the first synchronization rod 310 is facilitated by adopting a mode that the long waist holes are connected with the third rotating shaft.

As an alternative, the adapter 213 may correspond to two spring holders 211, as shown in fig. 8, and the two spring holders 211 are respectively located in the first recess and the third recess and are rotatably connected to the slider 220.

Referring to fig. 4 and 8, the adapter 231, the spring 232 and the spring frame 231 of the second elastic assembly 230 may be combined with the same components of the first elastic assembly 210, and detailed description thereof is omitted.

When the floating block slides along the first direction, the floating block can slide to a first set position and a second set position, wherein the first set position is far away from the rotation axis of the synchronizing rod and the bracket along the first direction, the first set position can also be called as the upper limit position of the floating block, and the upper limit position is the highest position where the floating block can slide limited by the limit bulge on the bracket. The second setting position is close to the rotation axis of the synchronous rod and the bracket, and the second setting position can also be called as the lower limit position of the floating block, and the lower limit position is the position at which the floating block slides downwards and is limited by the body structure of the bracket.

Referring to fig. 9 and 10, fig. 9 shows a corresponding schematic view of the damping mechanism when the terminal is in the deployed state; fig. 10 is a slider link mechanism equivalent to the damper mechanism. When the terminal is in the unfolded state, the first housing and the second housing are respectively arranged at two sides of the rotating shaft mechanism, the first synchronous rod 310 and the second synchronous rod of the corresponding damping mechanism are also arranged at two sides of the first axis, the length direction of the first synchronous rod 310 and the second synchronous rod is along the third axis, and the floating block 220 is limited at the upper limit position of the sliding stroke of the floating block by the bracket 100. With the floating structure orientation shown in FIG. 10 as a reference orientation, the first resilient member 210 and the second resilient member are at their longest deployed state when the slider 220 is at the upper limit position.

Referring to fig. 10, the damping mechanism may be equivalent to a slider link mechanism. Taking the first synchronization rod 310, the first elastic element 210 and the slider 220 as an example, the first synchronization rod 310 may be equivalent to a first link, the first elastic element 210 may be equivalent to a second link, the bracket may be equivalent to a third link, and the slider 220 may be equivalent to a slider. When the first elastic member 210, the first synchronizing bar 310, the bracket, and the slider 220 are equivalent to a slider link mechanism, the first synchronizing bar 310 is perpendicular to the second axis b of the bracket, the slider 220 is located at the upper limit position (first set position) of the sliding stroke, and the length of the first elastic member 210 is greater than the length of the first synchronizing bar 310.

For convenience of description, a shaft center B, a shaft center a, and a shaft center C are introduced, where the shaft center B represents a first rotating shaft of the first synchronizing rod 310 rotatably connected to the bracket, the shaft center C represents a third rotating shaft of the first synchronizing rod 310 rotatably connected to the first elastic component 210, and the shaft center a represents a second rotating shaft of the first elastic component 210 rotatably connected to the slider 220, and as can be seen with reference to fig. 10, the shaft center a, the shaft center B, and the shaft center C form a triangle.

In the first setting position, the distance between the axis A and the axis B is d1, i.e., the distance between the first and second shafts is d1, d1 is also understood to be the distance from the upper limit position of the slider 220 to the first shaft. The distance from the axis a to the axis C is d2, i.e. the distance between the second rotating shaft and the third rotating shaft is d2, and d2 can also be regarded as the length of the first elastic element 210. The length of the first synchronizing bar 310 is d0, i.e. the distance from the axis B to the axis C. As can be seen in fig. 10, the length d2 of the first elastic member 210 is greater than the length d0 of the first synchronizing bar 310, i.e., d2 > d 0.

In the flattened state of the damping mechanism provided in the embodiment of the present application, a triangle may be formed by the rotation axes (axis a, axis B, and axis C) between the first synchronizing rod 310, the first spring holder, the slider 220, and the first adapting member. The spring is compressed between the axis a and the axis C, and forces the axis a and the axis C to move away, i.e., the first synchronization rod 310 tends to rotate clockwise around the axis B. If the first synchronization lever 310 is to be rotated counterclockwise (in the direction of rotation when the terminal is closed) around the shaft center B, the spring force needs to be overcome to further compress the spring, and this force, i.e., the damping force needed to be provided by the closed damping mechanism, is placed inside the terminal to represent the operation force (operation hand feeling) when the terminal is folded.

When the terminal is folded, the first housing and the second housing rotate relatively to drive the damping mechanism to move, taking the first synchronizing bar 310 and the first elastic component 210 as an example, the first housing drives the first synchronizing bar 310 to rotate counterclockwise, the first synchronizing bar 310 drives the first elastic component 210 to rotate counterclockwise, the length of the first elastic component 210 is compressed, and the first elastic component 210 pushes the slider 220 to slide downward along the second axis b of the bracket (as shown by the arrow in fig. 10).

Referring to fig. 11 and 12, fig. 11 shows a schematic view of a state of the damping mechanism during folding, and fig. 12 shows a slider link mechanism corresponding to the damping mechanism in fig. 11. As the first housing rotates, the first elastic member 210 is compressed, the slider 220 slides downward along the third axis, the axis B slides in the direction of the axis a, and the slider 220 is located at the lower limit position of the slide stroke (second set position).

Referring to fig. 12, in the second setting position, the distance from the axial center a to the axial center B is d3, and it can also be understood that the distance between the first rotating shaft and the second rotating shaft is d3, and the axial center a and the axial center B overlap in fig. 12, that is, d3 is equal to 0. The distance from the axis A to the axis C is d 4. In fig. 12, d4 is d0, i.e., the length of the first elastic assembly 210 is equal to the length of the first synchronizing bar 310.

It will be appreciated that in the second set position, it is an alternative that the axes of the first and second shafts coincide, i.e. that the axes a and B coincide. In practical arrangements, the first pivot axis may alternatively be offset from the second pivot axis, i.e. the axis A and the axis B are offset when the slider is in the lower limit position. For example, the axis a may be located above or below the axis B with reference to the placement direction of the damping mechanism shown in fig. 12.

As can be seen from a comparison of fig. 10 and 12, during the folding process of the terminal, the first elastic member 210 is compressed (d2 > d4) while the slider 220 slides from the upper limit position to the lower limit position under the urging of the elastic force of the first elastic member 210, as the first synchronizing bar 310 rotates the first elastic member 210. In the above process, the deformation amount of the first elastic component 210 when the slider 220 is located at the first setting position is smaller than that of the first elastic component 210 when the slider 220 is located at the second setting position, i.e. d2 > d 4; meanwhile, the distance from the upper limit position of the slider 220 to the first rotation axis is smaller than the distance from the lower limit position thereof to the first rotation axis, i.e., d1 > d 3.

It can be seen from the above description that the elasticity of the spring can be sealed inside the damping mechanism, which is beneficial to the modular design of the damping mechanism on one hand, and on the other hand, the stress of the spring can not act on the parts outside the damping mechanism, and the requirements on the materials of other parts can be properly reduced, which is beneficial to simplifying the scheme.

Because the axis A around which the spring frame and the slider 220 rotate can change positions along with the slider 220 floating, when the first synchronization rod 310 rotates around the axis B all the time counterclockwise, the direction of the axis A under the action of the spring changes, and the slider 220 moves downwards, so that different hand feelings can be obtained by properly setting the lower limit position of the slider 220.

In the process of terminal folding, when the damping mechanism is in the flattening position, the force of the compressed spring to the axis A is inclined upwards, and the floating block 220 is kept at the upper limit position under the action of the elastic force; when the spring force applied to the axis a starts to have a downward component after the synchronization rod rotates a certain angle, the slider 220 moves downward to a lower limit position under the action of the spring force and stops at the lower limit position. In this example, the axis of the shaft center a is coaxial with the axis of the shaft center B when the slider 220 is set at the lower limit position, and the spring does not have an excessive amount of compression when the first synchronizing lever 310 is rotated continuously after the shaft center a and the shaft center B overlap, so that the force output by the damping mechanism is relatively constant from the state shown in fig. 12 to the time of complete folding.

In order to facilitate understanding of the damping force provided by the damping mechanism provided in the embodiment of the present application, the damping mechanism is simulated, and the simulation result is shown in fig. 13. As can be seen from fig. 13, in the flat state, the damping mechanism is required to have a larger force to keep the device flat, when the terminal needs to be folded, the spring in the damping mechanism is slightly compressed, and the triangular mechanism in the mechanism is damaged, so that the operating force is greatly reduced, and the terminal can be bent only by overcoming the friction force in the mechanism. Therefore, the damping mechanism that this application embodiment provided can provide great holding power under the flat state and guarantee the flat state at terminal, when needs folding terminal, only can need great power when beginning to fold, and the operating force reduces rapidly after folding more than certain angle, has promoted the operation and has felt. Meanwhile, the friction force in the damping mechanism is not too large, and the abrasion life of the lifting mechanism is prolonged.

In addition, the springs are compressed in the second direction in the embodiment of the application, and the number of the springs is not limited by the thickness direction (the first direction) and the bending radius of the damping mechanism. Can provide great elasticity, and is favorable for overcoming the problem of insufficient flattening force caused by instability of external factors (screen bending force). In addition, when the terminal begins to fold, the damping mechanism can provide large resistance, and in the folding process of the terminal, the damping mechanism provides small resistance, so that the operation experience can be greatly improved. Meanwhile, a floating triangular mechanism is formed among the synchronous component, the bracket and the damping component in the damping mechanism, and the phenomenon of overlarge damping in the process is effectively overcome.

Referring to fig. 14 to 17, fig. 14 to 17 provide another damping mechanism which is different from the damping mechanism shown in fig. 3 only in that the stroke of the slider 220 is changed, and thus, only an equivalent slider link mechanism will be described as an example.

The slider 220 is slidable in a first direction to a first set position (upper limit position), a second set position (intermediate position), and a third set position (lower limit position). The first setting position and the third setting position are positioned on two sides of the second setting position along the first direction; the first setting position is far away from the rotating axes of the synchronous rod and the bracket; the third setting position is close to the rotation axes of the synchronous rod and the bracket.

Referring to fig. 14, in the first set position, the corresponding terminal is in the unfolded state. The axis A is located at the upper limit of the slider 220 sliding stroke (point E), and the distance between the axis A and the axis B is d 1. The distance between the axis a and the axis C is d2, i.e. the length of the first elastic element 210 is d 2.

Referring to fig. 15, in the second setting position, the axis a is located at the middle position (point F) of the slider 220 sliding stroke, the corresponding end is at the position during folding, the distance between the axis a and the axis B is d3, in fig. 15, the axis a and the axis B are both located at the point F position, i.e., the axis a and the axis B overlap, and d3 is 0. The distance between the axis a and the axis C is d4, i.e. the length of the first elastic element 210 is d 4.

Referring to fig. 16, in the third setting position, the shaft center a is located at the lower limit position (point D) of the sliding stroke of the slider 220, and the corresponding terminal end is located at the position during folding, and the distance between the shaft center a and the shaft center B is D5. The distance between the axis a and the axis C is d6, i.e. the length of the first elastic element 210 is d 6.

Referring to fig. 17, fig. 17 corresponds to a schematic view of the damping mechanism in a folded state of the terminal. The axis A, the axis B and the axis C are located on the same axis, and the axis is parallel to the first direction. At this time, the length of the first elastic assembly 210 is d7, the length of the first synchronizing bar 310 is d0, and the distance between the axis a and the axis B is d5, so that the distance between d5, d7 and d0 satisfies: d0+ d5 ═ d 7.

As can be seen with reference to fig. 12 to 16, d1, d2, d3, d4, d5 and d6 satisfy: d1 > d 3; d2 > d 4; d5 > d 3; d6 > d 4. That is, during the folding of the terminal, slider 220 slides in the direction of point E-point F-point D, and during the sliding, first resilient component 210 compresses before expanding: the amount of deformation of the first resilient element 210 in the second set position is greater than the amount of deformation of the resilient element in the first set position (d2 > d4), and the amount of deformation of the first resilient element 210 in the second set position is greater than the amount of deformation of the resilient element in the third set position (d6 > d 4). It can be seen that during folding, the first elastic component 210 of the damping mechanism overcomes the stability of the triangular mechanism to provide a certain damping force, and then provides only a small damping force (the stroke between point E and point F) after overcoming the stability of the triangular mechanism. As the terminal end continues to fold, the spring of first elastic member 210 expands (travel between point F-point D), and first elastic member 210 may provide a force component that assists in folding the terminal end to facilitate terminal end folding. After the terminal is folded, referring to the structure shown in fig. 17, the axis a, the axis B, and the axis C are in a straight line, and when the terminal is opened, the spring force of the first elastic component 210 needs to be overcome to push the floating block 220 to slide from the point D to the point F, so that a certain force is required to open the terminal, that is, the damping mechanism provided in the embodiment of the present application can also provide a damping force when the terminal is opened. In addition, the force of the first elastic assembly 210 can also maintain the stability of the folded terminal after folding, thereby avoiding the terminal from unfolding when being accidentally subjected to external force.

It can be seen from the above description that, in addition to the effect of the damping mechanism shown in fig. 3, the damping mechanism provided in the embodiment of the present application can also provide a damping force when the terminal is unfolded by changing the stroke of the slider 220, so as to improve the hand feeling of the user when the terminal is opened.

In addition, it should be understood that the first elastic assembly in the above embodiment adopts a structure of a spring, a spring holder and a connecting member. However, the structure of the first elastic member is not particularly limited in the embodiments of the present application, and other structural members having a variable length may be used instead of the above structure. If a plastic spring is adopted to replace the component, or an elastic sheet is adopted to replace the structure. When the plastic spring and the elastic sheet are adopted, two ends of the plastic spring or the elastic sheet can be respectively connected with the floating block and the first synchronizing rod in a rotating mode. Of course, besides the above-mentioned plastic spring or elastic sheet, other elastic forms can be adopted, such as a compression cylinder, wherein the cylinder body and the piston rod of the compression cylinder are respectively connected with the slider and the first synchronous rod in a rotating manner, and the damping force is provided by air in the compression cylinder body during rotation.

In the above structure, a completely new damping structure is provided, and the damping force can be flexibly adjusted by adjusting the elastic force of the elastic component. In addition, the elastic force of the elastic component is sealed between the floating block and the synchronous connecting rod, on one hand, the modular design of the damping mechanism is facilitated, on the other hand, the stress of the elastic component cannot act on parts outside the damping mechanism, and the requirements on the materials of other parts can be properly reduced.

In the scheme, the stability of the virtual shaft oscillating bar in rotation is ensured through the real shaft oscillating bar and the connecting rod, and the reliability of the rotating shaft mechanism in operation is ensured.
