The flip mechanism and the locking mechanism are usually driven by a power mechanism and a transmission mechanism respectively.

[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0064] According to the first aspect of the present application, the present application provides a transmission mechanism, see Figure 1 , Figure 1 It is a structural schematic diagram of a transmission mechanism provided in an embodiment of the present application.

[0065] The transmission mechanism comprises: a main body 1 having a rotation axis, a guide groove structure is arranged on the main body 1 around the rotation axis, the guide groove structure comprises a first guide groove section 11 and a second guide groove section 13, the first guide groove section 11 comprises a first arc section 111 and a first traction section 112 which are connected to each other, the second guide groove section 13 comprises a second arc section 131 and a second traction section 132 which are connected to each other, the second arc section 131 and the first arc section 111 both take the rotation axis as the center of the circle, and the distance between at least one of the first traction section 112 and the second traction section 132 and the rotation axis is gradually arranged.

[0066] It can be understood that the first guide groove section 11 can be connected to a follower, and the second guide groove section 13 can also be connected to a follower, so that the transmission mechanism can be connected to two followers, thereby, one power mechanism can be used to drive the two followers to move through the transmission mechanism of the present application, for example, to drive the flipping mechanism and the locking mechanism of the flip screen to move, which helps to simplify the structure of the flip screen, save space and reduce costs. Therefore, compared with the solution of driving the movement of two followers by two sets of power mechanisms and transmission mechanisms in the related art, the transmission mechanism provided in the embodiment of the present application can realize that one power mechanism and one transmission mechanism drive the movement of two followers, which helps to simplify the structure of the flip screen, save space and reduce costs.

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

[0068] For ease of understanding and reading, in the embodiment of the transmission mechanism of the present application, the follower connected to the first guide groove section 11 is named as the first follower, and the follower connected to the second guide groove section 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 takes the rotation axis as the center of the circle, so that when the first follower is connected to the first arc segment 111, it does not move with the rotation of the body 1, and when the spacing between the first traction segment 112 and the rotation axis is arranged in a gradual manner, or when the first traction segment 112 is provided with a gear matching structure (sawtooth structure), the first follower connected to 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 and beneficial effects between the second guide groove segment 13 and the second follower are similar or identical to the relevant content between the first guide groove segment 11 and the first follower, and will not be repeated 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 act asynchronously, for example, when the first follower is connected to the first arc segment 111, the second follower is connected to the second traction segment 132, and when the first follower is connected to the first traction segment 112, the second follower is connected to the second arc segment 131. Still taking the above-mentioned flip screen as an example, when the transmission mechanism of the present application is used to drive the flip mechanism and the locking mechanism in the flip screen to act, it is possible to drive the flip mechanism to unfold the screen after driving the locking mechanism to unlock, so as to avoid damaging the components of the flip screen due to driving the flip mechanism to flip the screen without completing the unlocking, and it is also possible to drive the locking mechanism to lock the screen after driving the flip mechanism to fold the screen, so as to ensure the effectiveness of the locking. Therefore, the transmission mechanism provided in the embodiment of the present application can drive the two followers to act asynchronously, so that the transmission mechanism can be applied to more transmission scenarios.

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

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

[0072] It should be noted that the at least part here refers to the first traction segment 112 gradually approaching the rotation axis from the connection point with the first arc segment 111. 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 an arc segment with the rotation axis as the center (the distance between the arc segment and the rotation axis remains unchanged), or a straight line segment, and the distance between the straight line segment and the rotation axis gradually increases (see Figure 6 ). Preferably, as Figure 2 As shown, the first traction segment 112 gradually approaches the rotation axis relative to the first arc segment 111. The configuration of the second traction segment 132 is similar or identical to that of the first traction segment 112, and will not be described in detail herein.

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

[0074] By adopting such a scheme, the follower can be arranged on the same side of the main body 1, which is convenient for the preparation of the transmission mechanism on the one hand, and easy for the assembly between the follower and the transmission mechanism on the other hand, and helps to reduce the overall size of the follower and the transmission mechanism in the direction perpendicular to the surface where the guide groove structure is provided, thereby further saving space.

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

[0076] By making the first guide groove section 11 penetrate the body 1 , the first follower can be assembled from any side of the body 1 along the thickness direction of the body 1 , which can better meet the actual needs.

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

[0078] By making the second guide groove section 13 penetrate the body 1 , the second follower can be assembled from any side of the body 1 along the thickness direction of the body 1 , which can better meet the actual needs.

[0079] Exemplarily, by making the first guide groove section 11 and / or the second guide groove section 13 penetrate the body 1 , it is possible to respectively arrange the first follower and the second follower on two opposite surfaces of the body 1 .

[0080] For example, the body 1 has a first surface and a second surface that are arranged opposite to each other, the first guide groove section 11 runs through the first surface and the second surface, and the second guide groove section 13 runs through the first surface and the second surface. The first follower can be arranged on the first surface, and the second follower can be arranged on the second surface. Of course, both followers can be arranged on the first surface or the second surface. By making the first guide groove section 11 run through the body 1, and / or making the second guide groove section 13 run through the body 1, the two followers can be arranged in a variety of ways, which helps the transmission mechanism to be suitable for more transmission scenarios. At the same time, when the first follower and the second follower are respectively arranged on the first surface and the second surface of the body 1, making the first guide groove section 11 and the second guide groove section 13 run through the body 1 can reduce the distance between the first surface and the second surface (reduce the requirement for the thickness of the body 1), thereby reducing the space occupied by the transmission mechanism and reducing the cost of manufacturing the transmission mechanism.

[0081] In some embodiments, the first arc segment 111 is connected to the second arc segment 131. By connecting the first arc segment 111 and the second arc segment 131, the two can be at least partially reused, thereby helping to reduce the size of the body 1 and thus reduce 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 is helpful 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] See also Figure 2 , Figure 2 1 is a schematic diagram of another transmission mechanism provided in an embodiment of the present application. In some embodiments, the first arc segment 111 and the second arc segment 131 are isolated from each other. In some embodiments, the first arc segment 111 and the second arc segment 131 extend along circles of different radii with the rotation axis as the center.

[0084] By isolating the first arc segment 111 and the second arc segment 131 from each other, it is helpful to reduce the interference between the first follower and the second follower. The first arc segment 111 and the second arc segment 131 are arranged along circles with different radii with the rotation axis as the center, so that 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, helps to reduce the size of the body 1, thereby reducing the space occupied by the transmission mechanism, and at the same time, 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 disposed on two opposite surfaces of the body 1 .

[0086] By adopting such a solution, the transmission mechanism is applicable to the transmission scenario where the first driven member and the second driven member are arranged relative to the body 1, which helps to expand the application scope of the transmission mechanism.

[0087] It can be understood that the transmission mechanism can also include a shaft connection portion (not shown) connected to the body 1. The shaft connection portion is connected to the middle part of the body 1 and is staggered with the guide groove structure. The shaft connection portion is used to be fixedly connected to the output shaft of the driving member so that the transmission mechanism rotates under the drive of the driving member. It should be noted that the specific setting of the shaft connection portion can refer to the content in the relevant technology, and will not be introduced in detail here.

[0088] The second aspect of the present application provides a linkage device, see Figure 3 and Figure 4 , Figure 3This is a schematic diagram of a structure of a linkage device locking a to-be-turned part provided in an embodiment of the present application. Figure 4 It is a structural schematic diagram of a linkage device provided in an embodiment of the present application for unfolding a part to be flipped.

[0089] The linkage device includes the above-mentioned transmission mechanism, and also includes: a locking mechanism 2, having a first connecting end 20, the first connecting end 20 is slidably connected to the first guide groove section 11; a flipping mechanism 3, having a second connecting end 30, the second connecting end 30 is slidably connected to the second guide groove section 13; the transmission mechanism is configured to make the first connecting end 20 slide in the first guide groove section 11 and the second connecting end 30 slide in the second guide groove section 13 when rotating, so that when the first connecting end 20 slides in the first traction section 112, it can drive the locking mechanism 2 to lock or unlock the to-be-flipped member 4, and when the second connecting end 30 slides in the second traction section 132, it can drive the flipping mechanism 3 to expand or fold the to-be-flipped member 4.

[0090] When the transmission mechanism rotates, the first connecting end 20 slides in the first traction section 112, so that the locking mechanism 2 locks or unlocks the to-be-flipped part 4, and the second connecting end 30 slides in the second traction section 132, so that the flipping mechanism 3 unfolds or collapses the to-be-flipped part 4, thereby realizing one transmission mechanism driving two driven mechanisms (locking mechanism 2 and flipping mechanism 3) to move, thereby optimizing the solution in the related art that requires two power mechanisms and two transmission structures to drive the two driven mechanisms to move, reducing the number of power mechanisms and transmission mechanisms, reducing the space occupied by the linkage device, and reducing the production cost of the linkage device.

[0091] In addition, the second arc segment 131 and the first arc segment 111 both have the rotation axis as the center of the circle and are arranged adjacent to each other, which helps the locking mechanism 2 and the flipping mechanism 3 to be driven asynchronously to reduce interference. It can be achieved that after the transmission mechanism drives the locking mechanism 2 to unlock, it drives the flipping mechanism 3 to unfold the screen, thereby avoiding damage to the flipping screen parts due to driving the flipping mechanism 3 to flip the screen before completing the unlocking. It can also be achieved that after driving the flipping mechanism 3 to fold the screen, it drives the locking mechanism 2 to lock the screen, thereby ensuring the effectiveness of the locking.

[0092] In some embodiments, the transmission mechanism is configured to drive the locking mechanism 2 to switch between a locked state and an unlocked state when the first connecting end 20 slides in the first traction section 112, and to make the second connecting end 30 slide in the second arc section 131; and when the first connecting end 20 slides in the first arc section 111, the locking mechanism 2 maintains an unlocked state and drives the flipping mechanism 3 to expand or fold the flipped part 4.

[0093] When the first connection end 20 slides in the first traction section 112, the second connection 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 flipping mechanism 3 will not drive the to-be-flipped part 4 to move, and when the second connection end 30 slides in the second traction section 132, the locking mechanism 2 maintains the unlocked state, so that when the flipping mechanism 3 unfolds or retracts the to-be-flipped part 4, the locking mechanism 2 will not lock the to-be-flipped part 4. In this way, the action of the flipping mechanism 3 unfolding or retracting the to-be-flipped part 4 and the action of the locking mechanism 2 unlocking or locking the to-be-flipped part 4 are avoided from interfering with each other, which helps to improve the consistency and coordination of the linkage device.

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

[0095] By making the first connecting end 20 slide from the first arc segment 111 to the first traction segment 112 and the second connecting end 30 slide from the second traction segment 132 to the second arc segment 131, and by making the first connecting end 20 slide from the first traction segment 112 to the first arc segment 111 and the second connecting end 30 slide from the second arc segment 131 to the second traction segment 132, asynchronous action of the flipping mechanism 3 and the locking mechanism 2 can be achieved, thereby avoiding the mutual interference between the action of the flipping mechanism 3 and the action of the locking mechanism 2, and helping 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 the asynchronous action of the flipping mechanism 3 and the locking mechanism 2, thereby reducing the size of the transmission mechanism.

[0096] See also Figure 5 , Figure 5 yes Figure 3 In some embodiments, the locking mechanism 2 includes: a locking tongue slider 21, which is configured to lock the to-be-turned member 4 in the folded state when the locking mechanism 2 is in the locked state, and release the to-be-turned member 4 in the folded state when the locking mechanism 2 is in the unlocked state; a first connecting member 22, which is connected to the locking tongue slider 21; and a first sliding member 23, which is connected to the first connecting member 22, and the first sliding member 23 includes a first connecting end 20.

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

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

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

[0105] It should be noted that, if the part to be flipped 4 is to be unfolded, the locking mechanism 2 needs to unlock the part to be flipped 4 first, so the first traction section 112 can gradually approach the rotation axis relative to the first arc section 111, so that when the first connecting end 20 slides from the end of the first traction section 112 close to the rotation axis to the first arc section 111, the first connecting member 22 drives the lock tongue slider 21 to gradually move away from the part to be flipped 4 to release the part to be flipped 4. In some embodiments of the present application, when the first connecting member 22 is a cable, as the transmission mechanism rotates, the first connecting end 20 slides from the end of the first traction section 112 close to the rotation axis to the first arc section 111, but because the cable is a non-rigid structure, it cannot push the lock tongue slider 21 away from the to-be-turned member 4. Therefore, in some embodiments of the present application, a spring 252 is also connected to the lock tongue slider 21, and when the lock tongue slider 21 locks the to-be-turned member 4, the cable puts the spring 252 in a stretched state. Therefore, when the first connecting end 20 slides from the end of the first traction section 112 close to the rotation axis to the first arc section 111, under the elastic force of the spring 252, the lock tongue slider 21 is pulled to move in a direction away from the to-be-turned member 4, and the lock tongue slider 21 is connected to the cable, so the cable is always kept in a straight state. With such a solution, the elasticity of the spring 252 can be used to pull the lock tongue slider 21 to move. At the same time, the influence of the cable on the action of the linkage device when it is in a relaxed state can also be avoided.

[0106] See also Fig.10 , Fig.10 2 is a schematic diagram of a structure of another linkage device for locking a to-be-turned member provided in an embodiment of the present application. In some examples, the unlocking component 25 includes a first magnetic member 253, a second magnetic member 254 and a support 255; the first magnetic member 253 is disposed on the lock tongue slider 21, and the second magnetic member 254 is disposed on the support 255 and is disposed opposite to the first magnetic member 253.

[0107] It is understandable that when the unlocking assembly 25 includes the first magnetic member 253, the second magnetic member 254 and the support 255, the principle and technical effect of pulling the lock tongue slider 21 to move are similar to those of the spring 252, so it will not be repeated here. It should be noted that the first magnetic member 253 can be set as a permanent magnet and the second magnetic member 254 can be set as an electromagnet. Of course, other settings can also be used. For example, the first magnetic member 253 and the second magnetic member 254 are both electromagnets. The specific settings of the first magnetic member 253 and the second magnetic member 254 can be selected as needed, and the present application is not limited to this.

[0108] Please continue reading Figure 8 and Fig. 9In some embodiments, the first sliding member 23 is a rigid shaft, one end of which is connected to the cable, and the other end is the first connecting end 20. In some embodiments, the locking mechanism 2 further includes a guide wheel 221, the cable is overlapped on the guide wheel 221, and the guide wheel 221 is configured to guide the cable to move and keep the pulling force of the cable on the lock tongue slider 21 unchanged in direction.

[0109] The guide wheel 221 is used to keep the pulling force of the cable on the lock tongue slider 21 constant, which helps to maintain the stability of the movement of the lock tongue slider 21. 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 be affected by the pulling force of the cable.

[0110] In some embodiments, the flipping mechanism 3 includes: a second sliding member 31 including a second connecting end 30 ; a transition member 33 configured to be force-coupled with the to-be-flipped member 4 ; and a second connecting member 32 connecting the second sliding member 31 and the transition member 33 .

[0111] Please continue reading Figure 6 In some embodiments, the second connecting member 32 is a connecting rod, one end of which is connected to the second sliding member 31, and the other end is connected to the adapter 33. In some embodiments, the adapter 33 is a rack, one end of which is connected to the second connecting member 32, and the other end is meshed with a gear on the to-be-turned 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 member 33 coplanar and connected in a Z-shape, it helps to reduce the space occupied by the flipping mechanism 3 , thereby reducing the space occupied by the linkage device.

[0113] See also Figures 11 to 14 , Fig.11 This is a schematic diagram of a structure of another linkage device locking a to-be-turned member provided in an embodiment of the present application. Fig.12 yes Fig.11 Exploded diagram of the linkage provided, Fig.13 yes Fig.11 A schematic diagram of the structure of the gear assembly in the linkage device provided, Fig.14 yes Fig.11A schematic diagram of the structure of the transmission mechanism in the linkage device is provided. In some embodiments, the second traction section 132 is an arc-shaped guide groove with a sawtooth structure on the side wall of at least one side, and the second sliding member 31 is a gear assembly, including a sliding shaft 311, a first gear 312 and a second gear 313, one end of the sliding shaft 311 is a second connecting end 30, and the other end of the sliding shaft 311 is fixedly connected with a first gear 312 and a second gear 313 arranged in a stacked manner, and the first gear 312 is close to the second connecting end 30, and the first gear 312, the second gear 313 and the sliding shaft 311 are coaxially arranged; the adapter 33 is an output shaft, which is connected to the to-be-turned member 4; the second connecting member 32 is a gear belt, which is respectively engaged with the second gear 313 and the output shaft.

[0114] By using the gear assembly, when the second connecting end 30 slides to the connection between the second arc segment 131 and the second traction segment 132, the sawtooth structure provided on the side wall of the first gear 312 and the second traction segment 132 meshes, so that when the transmission mechanism rotates, the first gear 312 rotates under the drive of the sawtooth structure on the side wall of the second traction segment 132, 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-turned member 4 to move. The arrangement of the gear assembly makes the second traction segment 132 still arc-shaped. Compared with the scheme in which the spacing between the second traction segment 132 and the rotation axis is gradually arranged, when the second traction segment 132 is arc-shaped, the distance between the second traction segment 132 and the second arc segment 131 and the rotation axis can be reduced, 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 at this time, the first gear 312 is clamped together with the second gear 313 along its axial direction. Preferably, the second sliding member 31 is a stepped gear.
