[0063] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative effort fall within the protection scope of the present application.

[0064] According to a first aspect of the present application, the present application provides a transmission mechanism, please refer to Figure 1 , Figure 1 FIG. 1 is a structural schematic diagram of a transmission mechanism provided by an embodiment of the present application.

[0065] The transmission mechanism comprises a body 1 having a rotation axis, and a guide groove structure is arranged around the rotation axis on the body 1. The guide groove structure comprises a first guide groove segment 11 and a second guide groove segment 13. The first guide groove segment 11 comprises a first arc segment 111 and a first traction segment 112 which are in communication with each other. The second guide groove segment 13 comprises a second arc segment 131 and a second traction segment 132 which are in communication with each other. The second arc segment 131 and the first arc segment 111 are both centered on the rotation axis. The distance between at least one of the first traction segment 112 and the second traction segment 132 and the rotation axis is gradually changed.

[0066] It can be understood that the first guide groove segment 11 can be connected with a driven member, and the second guide groove segment 13 can also be connected with a driven member, so that the transmission mechanism can be connected with two driven members. Thus, one power mechanism can drive two driven members to act through the transmission mechanism of the present application, for example, driving the turnover mechanism and the locking mechanism of the turnover screen to act, which helps to simplify the structure of the turnover screen, save space and reduce cost. Therefore, compared with the scheme in the related art that two sets of power mechanisms and transmission mechanisms are used to drive two driven members to act, the transmission mechanism provided by the embodiment of the present application can realize that one power mechanism and one transmission mechanism drive two driven members to act, which helps to simplify the structure of the turnover screen, save space and reduce cost.

[0067] In some embodiments, the first guide groove segment 11 and the second guide groove segment 13 are arranged in a non-rotationally symmetric manner.

[0068] For the convenience of understanding and reading, in the embodiments of the transmission mechanism of the present application, the follower connected with the first guide groove segment 11 is named as the first follower, and the follower connected with the second guide groove segment 13 is named as the second follower.

[0069] In some embodiments, the first guide groove segment 11 and the second guide groove segment 13 are arranged in a non-rotationally symmetrical manner, and the first arc segment 111 is taken as the center of a circle with the rotation axis as the center, so that when the first follower is connected with the first arc segment 111, the first follower does not move with the rotation of the body 1, and when the distance between the first traction segment 112 and the rotation axis is arranged in a gradual change manner, or the first traction segment 112 is provided with a gear matching structure (sawtooth structure), the first follower connected with the first traction segment 112 will move with the rotation of the body 1. The arrangement of the second traction segment 132 can refer to the content of the first traction segment 112, and the connection relationship between the second guide groove segment 13 and the second follower and the beneficial effects are similar or identical to the related content between the first guide groove segment 11 and the first follower, which will not be described here. Therefore, by controlling the connection positions of the first follower and the second follower with the guide groove structure, the two followers can be made to move asynchronously, for example, the second follower is connected with the second traction segment 132 when the first follower is connected with the first arc segment 111, and the second follower is connected with the second arc segment 131 when the first follower is connected with the first traction segment 112. Still taking the above-mentioned flip screen as an example, when the transmission mechanism of the present application drives the flip mechanism and the locking mechanism in the flip screen to move, it can be realized that the flip mechanism is driven to unfold the screen after the locking mechanism is unlocked, avoiding damaging the components of the flip screen due to the flip mechanism being driven to flip the screen before the unlocking is completed. It can also be realized that the locking mechanism is driven to lock the screen after the flip mechanism is driven to fold the screen, ensuring the effectiveness of the locking. Therefore, the transmission mechanism provided in the embodiments of the present application can drive two followers to move asynchronously, so that the transmission mechanism can be applied to more transmission scenes.

[0070] In some embodiments, the first traction segment 112 is gradually close to the rotation axis at least partially relative to the first arc segment 111.

[0071] In some embodiments, the second traction segment 132 is gradually close to the rotation axis at least partially relative to the second arc segment 131.

[0072] It should be noted that at least partially here means that the first traction segment 112 gradually approaches the rotation axis from the connection position with the first arc segment 111, and when the distance between the first traction segment 112 and the rotation axis reaches the minimum value, the other part of the first traction segment 112 away from the first arc segment 111 can be a circular arc segment (the distance between the circular arc segment and the rotation axis remains unchanged) taken as the center of a circle with the rotation axis as the center, or a straight line segment, and the distance between the straight line segment and the rotation axis gradually increases (for reference Figure 6 ). Preferably, as shown in FIG. 1, the first traction segment 112 is gradually close to the rotation axis at least partially relative to the first arc segment 111.Figure 2 As shown, the first traction segment 112 gradually approaches the rotation axis relative to the first arc segment 111. The second traction segment 132 is arranged in a similar or same manner as the first traction segment 112, and thus will not be described herein.

[0073] In some embodiments, the first guide groove segment 11 and the second guide groove segment 13 are arranged on the same surface of the body 1.

[0074] With such an arrangement, the driven members can be arranged on the same side of the body 1, which on one hand facilitates the manufacturing of the transmission mechanism, and on the other hand facilitates the assembly between the driven members and the transmission mechanism, and helps to reduce the size of the driven members and the transmission mechanism in the direction perpendicular to the surface on which the guide groove structure is arranged, thereby further saving space.

[0075] In some embodiments, the first guide groove segment 11 penetrates through the body 1.

[0076] By making the first guide groove segment 11 penetrate through the body 1, the first driven member can be assembled from either side of the body 1 along the thickness direction thereof, which can better meet the actual needs.

[0077] In some embodiments, the second guide groove segment 13 penetrates through the body 1.

[0078] By making the second guide groove segment 13 penetrate through the body 1, the second driven member can be assembled from either side of the body 1 along the thickness direction thereof, which can better meet the actual needs.

[0079] For example, by making the first guide groove segment 11 and / or the second guide groove segment 13 penetrate through the body 1, the first driven member and the second driven member can be arranged on two opposite surfaces of the body 1, respectively.

[0080] For example, the body 1 has a first surface and a second surface arranged oppositely, the first guide groove segment 11 penetrates through the first surface and the second surface, and the second guide groove segment 13 penetrates through the first surface and the second surface, the first driven member can be arranged on the first surface, and the second driven member can be arranged on the second surface. Of course, both of the driven members can also be arranged on the first surface or the second surface. By making the first guide groove segment 11 penetrate through the body 1, and / or making the second guide groove segment 13 penetrate through the body 1, the two driven members have multiple arrangement modes, which helps the transmission mechanism to be applicable to more transmission scenarios. Meanwhile, in the case that the first driven member and the second driven member are arranged on the first surface and the second surface of the body 1, respectively, making the first guide groove segment 11 and the second guide groove segment 13 both penetrate through the body 1 can reduce the distance between the first surface and the second surface (reduce the requirement on the thickness of the body 1), thereby reducing the space occupied by the transmission mechanism, and also reducing the cost of manufacturing the transmission mechanism.

[0081] In some embodiments, the first arc segment 111 is in communication with the second arc segment 131. By making the first arc segment 111 in communication with the second arc segment 131, the two can be at least partially multiplexed, thereby helping to reduce the size of the body 1, thereby reducing the space occupation.

[0082] In some embodiments, the first arc segment 111 and the second arc segment 131 are located on the same circle with the rotation axis as the center. By making the first arc segment 111 and the second arc segment 131 located on the same circle with the rotation axis as the center, it helps to reduce the space occupied by the guide groove structure in the radial direction of the body 1, which is conducive to reducing the size of the body 1.

[0083] Please refer to Figure 2 , Figure 2 is a structural schematic diagram of another transmission mechanism provided by the embodiments of the present application. In some embodiments, the first arc segment 111 is isolated from the second arc segment 131. In some embodiments, the first arc segment 111 and the second arc segment 131 extend along different radii of circles with the rotation axis as the center, respectively.

[0084] By making the first arc segment 111 and the second arc segment 131 isolated from each other, it helps to reduce the interference between the first driven member and the second driven member. By making the first arc segment 111 and the second arc segment 131 extend along different radii of circles with the rotation axis as the center, the first arc segment 111 and the second arc segment 131 can partially overlap, which helps to reduce the space occupied by the guide groove structure in the circumferential direction of the body 1, which is conducive to reducing the size of the body 1, thereby reducing the space occupied by the transmission mechanism, and at the same time, it helps to reduce the cost of manufacturing the transmission mechanism.

[0085] In some embodiments, the first guide groove segment 11 and the second guide groove segment 13 are respectively arranged on two surfaces of the body 1 arranged opposite to each other.

[0086] With such a solution, the transmission mechanism is suitable for the transmission scenario in which the first driven member and the second driven member are arranged opposite to each other with respect to the body 1, which helps to expand the application range of the transmission mechanism.

[0087] It can be understood that the transmission mechanism can further include a shaft connecting portion (not shown in the figure) connected with the body 1. The shaft connecting portion is connected with the middle part of the body 1 and is arranged in a staggered manner with the guide groove structure. The shaft connecting portion is used for fixedly connecting with the output shaft of the driving member, so that the transmission mechanism is driven to rotate by the driving member. It should be noted that the specific arrangement of the shaft connecting portion can refer to the content in the related art, which will not be introduced here.

[0088] The second aspect of the present application provides a linkage device, please refer to Figure 3 and Figure 4 , Figure 3is a structure schematic diagram of a linkage device locking a to-be-flipped part provided by an embodiment of the present application, Figure 4 is a structure schematic diagram of a linkage device unfolding a to-be-flipped part provided by an embodiment of the present application.

[0089] The linkage device comprises the transmission mechanism and further comprises: a locking mechanism 2 having a first connecting end 20, the first connecting end 20 being in sliding connection with the first guide groove segment 11; and a flipping mechanism 3 having a second connecting end 30, the second connecting end 30 being in sliding connection with the second guide groove segment 13; the transmission mechanism is configured to, when rotating, slide the first connecting end 20 in the first guide groove segment 11 and slide the second connecting end 30 in the second guide groove segment 13, so as to enable the locking mechanism 2 to lock or unlock the to-be-flipped part 4 when the first connecting end 20 slides in the first traction segment 112, and enable the flipping mechanism 3 to unfold or fold the to-be-flipped part 4 when the second connecting end 30 slides in the second traction segment 132.

[0090] When the transmission mechanism rotates, the first connecting end 20 is slid in the first traction segment 112 to make the locking mechanism 2 lock or unlock the to-be-flipped part 4, and the second connecting end 30 is slid in the second traction segment 132 to make the flipping mechanism 3 unfold or fold the to-be-flipped part 4, so that one transmission mechanism drives two driven mechanisms (the locking mechanism 2 and the flipping mechanism 3) to act, which optimizes the scheme in the prior art that two power mechanisms and two transmission structures are required to drive two driven mechanisms to move, reduces the number of power mechanisms and transmission mechanisms, reduces the space occupied by the linkage device, and reduces the production cost of the linkage device.

[0091] In addition, the second arc-shaped segment 131 and the first arc-shaped segment 111 are both centered on the rotation axis and are arranged adjacent to each other, which helps the locking mechanism 2 and the flipping mechanism 3 to be driven asynchronously, reduces interference, enables the transmission mechanism to drive the flipping mechanism 3 to unfold the screen after driving the locking mechanism 2 to unlock, avoids damaging the components of the flipping screen due to the flipping mechanism 3 being driven to flip the screen before unlocking is completed, and further enables the transmission mechanism to drive the locking mechanism 2 to lock the screen after driving the flipping mechanism 3 to fold the screen, thereby ensuring the effectiveness of locking.

[0092] In some embodiments, the transmission mechanism is configured to, when the first connecting end 20 slides in the first traction segment 112, drive the locking mechanism 2 to switch between the locking state and the unlocking state and slide the second connecting end 30 in the second arc-shaped segment 131; and when the first connecting end 20 slides in the first arc-shaped segment 111, maintain the locking mechanism 2 in the unlocking state and drive the flipping mechanism 3 to unfold or fold the to-be-flipped part 4.

[0093] By making the first connecting end 20 slide in the first traction section 112, the second connecting end 30 slides in the second arc section 131, so that when the locking mechanism 2 switches between the locked state and the unlocked state, the turnover mechanism 3 does not drive the turnover piece 4 to act, and by making the second connecting end 30 slide in the second traction section 132, the locking mechanism 2 maintains the unlocked state, so that when the turnover mechanism 3 expands or folds the turnover piece 4, the locking mechanism 2 does not lock the turnover piece 4. In this way, the action of the turnover mechanism 3 expanding or folding the turnover piece 4 does not interfere with the action of the locking mechanism 2 unlocking or locking the turnover piece 4, which helps to improve the consistency and coordination of the linkage device.

[0094] In some embodiments, the transmission mechanism is configured to make the second connecting end 30 slide to the second arc section 131 from the second traction section 132 when the first connecting end 20 slides to the first traction section 112 from the first arc section 111; and / or make the second connecting end 30 slide to the second traction section 132 from the second arc section 131 when the first connecting end 20 slides to the first arc section 111 from the first traction section 112.

[0095] By making the first connecting end 20 slide to the first traction section 112 from the first arc section 111, the second connecting end 30 slides to the second arc section 131 from the second traction section 132, and by making the first connecting end 20 slide to the first arc section 111 from the first traction section 112, the second connecting end 30 slides to the second traction section 132 from the second arc section 131, the turnover mechanism 3 and the locking mechanism 2 can be made to act asynchronously, avoiding the situation that the action of the turnover mechanism 3 interferes with the action of the locking mechanism 2, which helps to improve the consistency and coordination of the linkage device; in addition, it helps to minimize the layout length of the guide groove structure on the basis of ensuring that the turnover mechanism 3 and the locking mechanism 2 act asynchronously, thereby reducing the size of the transmission mechanism.

[0096] Please refer to Figure 5 , Figure 5 is Figure 3 the top view of the linkage device locking the turnover piece in In some embodiments, the locking mechanism 2 includes: a lock tongue slider 21 configured to lock the turnover piece 4 in the folded state when the locking mechanism 2 is in the locked state, and release the turnover piece 4 in the folded state when the locking mechanism 2 is in the unlocked state; a first connecting piece 22 connected with the lock tongue slider 21; a first sliding piece 23 connected with the first connecting piece 22, and the first sliding piece 23 includes a first connecting end 20.

[0097] In some examples, the locking mechanism 2 includes a plurality of lock tongue sliders 21, and the plurality of lock tongue sliders 21 are connected by a lock tongue connecting rod 24.

The device utilizes a non-connected first guide groove segment 11 and a second guide groove segment 13, which are respectively connected to the locking mechanism 2 and the flipping mechanism 3, to control the component to be flipped 4. It should be noted that the descriptions of the locking mechanism 2 and the flipping mechanism 3 in the following embodiments also apply to the linkage device provided in this embodiment.

[0102] In some embodiments, the first connector 22 is a cable, one end of which is connected to the latch slider 21 and the other end is connected to the first slider 23.

[0103] In some embodiments, the locking mechanism 2 further includes an unlocking component 25, which is configured to cooperate with the first connector 22 to pull the locking tongue slider 21 to move when the first connecting end 20 slides within the first traction section 112.

[0104] Please continue reading. Figure 8 In some embodiments, the unlocking component 25 includes: a spring seat 251; and a spring 252, one end of which is connected to the latch slider 21 and the other end of which is connected to the spring seat 251.

[0105] It should be noted that in order to unfold the to-be-flipped part 4, the locking mechanism 2 needs to be unlocked first, so the first traction section 112 can gradually approach the rotation axis relative to the first arc-shaped section 111, so as to facilitate the first connecting end 20 to slide from one end of the first traction section 112 close to the rotation axis to the first arc-shaped section 111, and the first connecting piece 22 drives the lock tongue slider 21 to gradually move away from the to-be-flipped part 4, so as to release the to-be-flipped part 4. In some embodiments of the present application, when the first connecting piece 22 is a cable, with the rotation of the transmission mechanism, the first connecting end 20 slides from one end of the first traction section 112 close to the rotation axis to the first arc-shaped section 111, but because the cable is a non-rigid structure, it cannot push the lock tongue slider 21 away from the to-be-flipped part 4, so in some embodiments of the present application, the lock tongue slider 21 is further connected with a spring 252, and the spring 252 is in a stretched state when the cable locks the to-be-flipped part 4. Therefore, when the first connecting end 20 slides from one end of the first traction section 112 close to the rotation axis to the first arc-shaped section 111, the lock tongue slider 21 is pulled away from the to-be-flipped part 4 under the elastic force of the spring 252, and the lock tongue slider 21 is connected with the cable, so that the cable always remains in a straight state. By using such a scheme, the spring 252 can be used to elastically pull the lock tongue slider 21 to move. At the same time, the influence of the cable in a relaxed state on the action of the linkage device can also be avoided.

[0106] Please refer to Figure 10 , Figure 10 is another structure diagram of a linkage device provided by the embodiments of the present application for locking a to-be-flipped part. In some examples, the unlocking assembly 25 includes a first magnetic attraction piece 253, a second magnetic attraction piece 254, and a support 255; the first magnetic attraction piece 253 is arranged on the lock tongue slider 21, the second magnetic attraction piece 254 is arranged on the support 255, and is arranged opposite to the first magnetic attraction piece 253.

[0107] It can be understood that when the unlocking assembly 25 includes the first magnetic attraction piece 253, the second magnetic attraction piece 254, and the support 255, the principle and technical effects of pulling the lock tongue slider 21 to move are similar to those of the spring 252, so they will not be described here. It should be noted that the first magnetic attraction piece 253 can be a permanent magnet, and the second magnetic attraction piece 254 can be an electromagnet, of course, other arrangement methods can also be used, such as the first magnetic attraction piece 253 and the second magnetic attraction piece 254 are both electromagnets, and the specific arrangement method of the first magnetic attraction piece 253 and the second magnetic attraction piece 254 can be selected as needed, and the present application is not limited thereto.

[0108] Please continue to refer to Figure 8 and Figure 9In some embodiments, the first sliding member 23 is a rigid shaft, one end of which is connected with the pull cable, and the other end is the first connecting end 20. In some embodiments, the locking mechanism 2 further comprises a guide wheel 221, the pull cable is lapped on the guide wheel 221, and the guide wheel 221 is configured to guide the movement of the pull cable and keep the pulling force of the pull cable on the lock tongue slider 21 unchanged.

[0109] The use of the guide wheel 221 to keep the pulling force of the pull cable on the lock tongue slider 21 unchanged helps to keep the smoothness of the movement of the lock tongue slider 21. And the rigid shaft can make the sliding of the first connecting end 20 in the first arc segment 111 and the first traction segment 112 not affected by the pulling force of the pull cable.

[0110] In some embodiments, the turnover mechanism 3 comprises: a second sliding member 31 comprising a second connecting end 30; an adapter 33 configured to be force-coupled with the to-be-turned-over member 4; and a second connecting member 32 connecting the second sliding member 31 and the adapter 33.

[0111] Please continue to refer to Figure 6 In some embodiments, the second connecting member 32 is a connecting rod, one end of which is connected with the second sliding member 31, and the other end is connected with the adapter 33. In some embodiments, the adapter 33 is a rack, one end of which is connected with the second connecting member 32, and the other end is engaged with a gear on the to-be-turned-over member 4. In some embodiments, the second sliding member 31 is a rotating shaft. In some embodiments, the second sliding member 31, the second connecting member 32, and the adapter 33 are coplanar and connected in a Z shape.

[0112] By making the second sliding member 31, the second connecting member 32, and the adapter 33 coplanar and connected in a Z shape, it helps to reduce the space occupied by the turnover mechanism 3, thereby reducing the space occupied by the linkage device.

[0114] The gear assembly allows the first gear 312 to be engaged with the sawtooth structure on the side wall of the second traction section 132 when the second connecting end 30 slides to the connection between the second arc-shaped section 131 and the second traction section 132, so that the first gear 312 rotates under the drive of the sawtooth structure on the side wall of the second traction section 132 when the transmission mechanism rotates, and drives the second gear 313 to rotate, and then drives the output shaft to rotate through the gear belt, and finally drives the to-be-tilted member 4 to act. The arrangement of the gear assembly allows the second traction section 132 to remain arc-shaped, which can reduce the distance between the second traction section 132 and the second arc-shaped section 131 and the rotation axis center, thereby reducing the volume of the transmission mechanism, making the linkage device compact in structure, and reducing the production cost. In some embodiments, the sliding shaft 311 can be omitted, and the first gear 312 is then clamped together with the second gear 313 along the axial direction thereof.
