DETAILED DESCRIPTION
[0076] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0077] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0078] The linkage device, transmission device, display screen system and vehicle provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0079] Reference Figure 1 to Figure 2 An embodiment of the present application provides a linkage device, including a fixed component 1, a transmission mechanism 2 and a bracket 3; the transmission mechanism 2 is slidably connected to the fixed component 1 along a first direction, and the bracket 3 is hinged to the transmission mechanism 2; when the bracket 3 is in a preset state relative to the fixed component 1, the bracket 3 rotates relative to the transmission mechanism 2 while the transmission mechanism 2 slides relative to the fixed component 1 in a preset direction of the first direction.
[0080] Specifically, if Figure 1 to Figure 2 As shown, the linkage device provided in the embodiment of the present application can be used for display screen systems, mobile phone mounting brackets or other multimedia devices. The linkage device includes a fixing component 1, a transmission mechanism 2 and a bracket 3. The fixing component 1 is a fixed support body of the linkage device, such as Fig.15 As shown, the transmission mechanism 2 is connected to the fixing assembly 1 by sliding along the first direction A, and the bracket 3 is hinged with the transmission mechanism 2 to realize mutual rotation. Therefore, driven by the transmission mechanism 2, the bracket 3 rotates around the vertical direction and slides in translation at the same time, realizing a composite motion, which can make the display screen adapt to different lighting angles and brightness to meet driving needs.
[0081] Combination Fig.15As shown in Figure b, the bracket 3 is in a state where there is no angular deflection relative to the fixing assembly 1. In this state, the surface of the bracket 3 connected to the display screen is parallel to the height direction of the fixing assembly 1 itself, so that the surface of the display screen is parallel to the width direction of the vehicle, and the display screen and the bracket 3 are in the center. Fig.15 In the figure b, the direction changes to figure a or figure c. No matter the bracket 3 deflects to the left or right relative to the transmission mechanism 2, the transmission mechanism 2 slides along the direction A relative to the fixed component 1. Fig. 9 The stop position at the upper end of the first slide groove 111 moves to the side stop position at the lower end. The A direction has a sub-movement along the C direction, which is the moving avoidance direction, along the width direction of the vehicle, from the main driver's seat to the co-driver's seat.
[0082] The linkage device provided in the embodiment of the present application can drive the target object, such as a mobile phone, a display screen or a car speaker, to output a composite movement of translation and horizontal deflection under the drive of the transmission mechanism. Regardless of whether the bracket deflects to the left or to the right relative to the transmission mechanism, the transmission mechanism moves in a preset direction of the first direction relative to the fixed component to avoid the target object, that is, to achieve a sideways turn of the target object while sliding in the direction toward the co-pilot, thereby ensuring the user's driving safety.
[0083] Optionally, refer to Fig.15 When the bracket 3 moves from a non-preset state to a preset state relative to the fixing component 1, while the bracket 3 rotates relative to the transmission mechanism 2, the transmission mechanism 2 slides relative to the fixing component 1 along a first direction opposite to the preset direction.
[0084] Specifically, if Fig.15 As shown, in the process from Figure a to Figure b, when the bracket 3 moves from the left-biased state to the middle preset state relative to the fixed component 1, the bracket rotates relative to the transmission mechanism 2 while the transmission mechanism slides relative to the fixed component along the negative A direction; in the process from Figure c to Figure b, when the bracket 3 moves from the right-biased state to the middle preset state relative to the fixed component 1, the bracket rotates relative to the transmission mechanism 2 while the transmission mechanism slides relative to the fixed component along the negative A direction. Among them, the negative A direction corresponds to Fig. 9 The movement from the side stop position at the lower end of the first slide groove 111 to the stop position at the upper end is also in the opposite direction to the preset direction.
[0085] Optionally, refer to Figure 1 , Figure 2 and Figure 7, also includes a driving mechanism 4; the driving mechanism 4 is connected to the transmission mechanism 2; the driving mechanism 4 drives the transmission mechanism 2 to slide along the first direction relative to the fixed component 1, while driving the bracket 3 to rotate relative to the transmission mechanism 2; and / or, the driving mechanism 4 drives the transmission mechanism 2 to rotate relative to the bracket 3, while driving the transmission mechanism 2 to slide along the first direction relative to the fixed component 1.
[0086] Specifically, the driving mechanism 4 may be in the form of, but not limited to, hydraulic drive, pneumatic drive or motor drive. The driving mechanism 4 is connected to the transmission mechanism 2. In one embodiment, the driving mechanism 4 drives the transmission mechanism 2 to operate, and while a portion of the structure of the transmission mechanism 2 moves and avoids relative to the fixed component 1 along a first direction, it drives the bracket 3 to deflect horizontally, i.e., turn sideways, relative to the transmission mechanism 2. In another embodiment, the driving mechanism 4 drives the transmission mechanism 2 to operate, so that while the transmission mechanism 2 deflects horizontally relative to the bracket 3, it drives a portion of the structure of the transmission mechanism 2 to move and avoid relative to the fixed component 1 along the first direction. The actual movement may realize any one of the embodiments or two of the embodiments, and therefore, during the movement, a composite movement may be realized in which the bracket 3 deflects horizontally while moving and avoiding relative to the fixed component 1 along the first direction.
[0087] Optionally, refer to Figure 8 , Fig. 9 and Fig.15 The fixing component 1 is provided with a first sliding groove 111 , and the first sliding groove 111 extends along the first direction. The transmission mechanism 2 is slidably connected to the fixing component 1 through the first sliding groove 111 .
[0088] Optionally, refer to Figures 2 to 6 The transmission mechanism 2 includes a first transmission component 21, a second transmission component 22 and a base 23; the fixed component 1 is also provided with a second slide groove 121, the first transmission component 21 and the fixed component 1 are slidably connected to the second slide groove 121, and are rotatably connected to the bracket 3; the base 23 and the fixed component 1 are slidably connected to the first slide groove 111, and are hinged to the bracket 3 through the second transmission component 22; the driving mechanism 4 is connected to the first transmission component 21 and / or the base 23.
[0089] Specifically, if Figure 8 and Fig. 9As shown, the fixing component 1 is provided with a first slide groove 111 and a second slide groove 121, which can be located on the left and right sides or the top and bottom surfaces of the fixing component 1. A certain angle is formed between the first slide groove 111 and the second slide groove 121, and the angle can be 60°, 70°, 80° or 90°. Different movement trajectories of the complex can be formed by designing different slide groove directions. Fig.12 and Fig.15 In this embodiment, the first slide groove 111 and the second slide groove 121 are perpendicular to each other. Part of the transmission mechanism 2 is slidably connected to the first slide groove 111 with the fixing component 1, and the other part is slidably connected to the second slide groove 121 with the fixing component 1.
[0090] Specifically, if Figures 2 to 6 As shown, the transmission mechanism 2 includes a first transmission component 21, a second transmission component 22 and a base 23. The first transmission component 21 is slidably connected to the second slide slot 121 and is rotatably connected to the bracket 3. The base 23 is slidably connected to the first slide slot 111 and is rotatably connected to the bracket 3 through the second transmission component 22: in one embodiment, the second transmission component 22 is fixedly connected to the base 23 and is hinged to the bracket 3; in another embodiment, the second transmission component 22 is fixedly connected to the bracket 3 and is hinged to the base 23. The driving mechanism 4 is connected to the first transmission component 21 and / or the base 23: in one embodiment, the driving mechanism 4 is arranged inside the base 23, and its power output end is connected to the first transmission component 21 to directly drive the first transmission component 21 to move; in another embodiment, the driving mechanism 4 is arranged outside the linkage device, and its power output end is connected to the base 23 to drive the base 23 to move, but the driving mechanism 4 itself is relatively fixed.
[0091] Therefore, in this embodiment, by setting the first transmission component 21, the second transmission component 22 and the base 23, under the drive of the driving mechanism 4, on the one hand, the first transmission component 21 realizes relative sliding with the fixed component 1 through the second slide groove 121, and on the other hand, the base 23 realizes horizontal rotation of the bracket 3 through the second transmission component 22, that is, it realizes the composite movement of the bracket in the form of movement avoidance and horizontal deflection relative to the fixed component.
[0092] Optionally, refer to Figure 2 and Figure 3 The first transmission assembly 21 includes a transmission arm 213, and the power output end of the driving mechanism 4 has a transmission shaft 46; the transmission shaft 46 is connected to the driving mechanism 4 or the base 23, and the transmission shaft 46 is gear-transmitted to the bracket 3. One end of the transmission arm 213 is connected to the transmission shaft 46, and the other end is slidably connected to the second slide groove 121.
[0093] Specifically, if Figure 2 and Figure 3 As shown, the first transmission assembly 21 includes a transmission arm 213, and the power output end of the driving mechanism 4 has a transmission shaft 46. When the driving mechanism 4 is arranged inside the base 23, the transmission shaft 46 is connected to the driving mechanism 4, and the transmission arm 213 is driven to swing under the drive of the driving mechanism 4; when the driving mechanism 4 is arranged outside the linkage device, the transmission shaft 46 is connected to the base 23, and when the driving mechanism 4 drives the base 23 to move, the transmission shaft 46 drives the transmission arm 213 to swing. The transmission arm 213 is a crank, one end of which is connected to the transmission shaft 46, and the other end is slidably connected to the second slide slot 121. The transmission shaft 46 and the bracket 3 are gear-driven, that is, a gear transmission mechanism is arranged between the transmission shaft 46 and the bracket 3, and the rotation of the transmission shaft 46 is output to the bracket 3. Therefore, when the transmission shaft 46 rotates, on the one hand, it drives the transmission arm 213 to swing, so that the other end of the transmission arm 213 slides along the second slide groove 121, and converts the torque transmitted by the transmission arm 213 into a thrust acting on the second slide groove 121, so as to drive the transmission mechanism 2 to perform a linear translational motion relative to the fixed component 1; on the other hand, it drives the bracket 3 to rotate horizontally relative to the base 23 through the gear transmission mechanism.
[0094] Optionally, refer to Figure 3 and Figure 4 The first transmission assembly 21 also includes a first transmission tooth 211 and a second transmission tooth 212; the first transmission tooth 211 is sleeved on the transmission shaft 46 and meshed with the second transmission tooth 212, and the second transmission tooth 212 is fixedly connected to the bracket 3.

The second transmission tooth 212 is a rack, which can be in a bar shape or an arc shape, meshing with the first transmission tooth 211, and the second transmission tooth 212 is fixed to the bracket 3 by screws. The transmission shaft 46 drives the first transmission tooth 211 to rotate, and then drives the bracket 3 to rotate around the vertical axis through the second transmission tooth 212, so as to realize the horizontal deflection movement of the bracket 3. In addition, this gear transmission structure is compact and saves assembly space.
[0096] Optionally, refer to Figure 4 and Fig.10 The second transmission assembly 22 includes a rotating shaft 221; the bracket 3 is provided with a first through hole 311, the base 23 is provided with a second through hole 231, the rotating shaft 221 passes through the second through hole 231 and the first through hole 311, and the bracket 3 is rotatably connected to the base 23 through the rotating shaft 221.
[0097] Specifically, if Figure 4 and Fig.10 As shown, the core component of the second transmission assembly 22 is the rotating shaft 221. At least one first through hole 311 is provided on the bracket 3. In the embodiment of the present application, the bracket 3 has a first connecting portion 31 and a second connecting portion 32 extending from the upper and lower parts. Each connecting portion has a first through hole 311, and the two first through holes 311 are coaxial. A second through hole 231 is provided on the base 23. The rotating shaft 221 passes through the first through hole 311 on the upper part of the bracket 3, the second through hole 231 on the base 23, and the first through hole 311 on the lower part of the bracket 3 in sequence. That is, the bracket 3 is rotatably connected to the base 23 through the rotating shaft 221.

[0099] Specifically, if Figure 2 , Figures 7 to 11 As shown, the first shell 11 and the second shell 12 are assembled and connected by screw fastening, and one side thereof has an opening for extending the bracket 3. The first shell 11 is the lower shell, and at least one first slide groove 111 is provided on the inner side thereof. In the embodiment of the present application, a first slide groove 111 is provided on both sides of the first shell 11, and the extension direction of the two first slide grooves 111 is the same. A second slide groove 121 is provided on the second shell 12. A second sliding portion 2131, i.e., a small crankshaft, is provided on the other end of the transmission arm 213. Driven by the rotation of the transmission shaft 46, the transmission arm 213 swings, and the second sliding portion 2131 is limited in the second slide groove 121 and slides along the second slide groove 121.

[0109] Specifically, if Figure 4 As shown, the mounting groove 312 is formed in the first connection portion 31 and communicates with the first through hole 311. When the rotating shaft 221 passes through the first through hole 311 of the bracket and the second through hole 231 of the base 23, the rotating shaft plate 223 is fixed in the mounting groove 312 to press and fix the bracket 3 and the base 23, increase the force bearing area of the bracket 3, and improve the connection stability.
[0110] Optionally, refer to Figure 4 The second transmission assembly 22 further includes a threaded fastener 224; the threaded fastener 224 passes through the rotating shaft disk 223, the first through hole 311, the second through hole 231 and the rotating shaft 221 in sequence.

At the same time, the elastic member 5 is compressed and installed between the base 23 and the shell, and can also rely on its own elasticity to play a role in buffering, shock absorption and impact resistance. In the embodiment of the present application, since the base 23 and the first shell 11 can be fixed relatively reliably by gravity, it is only necessary to arrange the elastic member 5 between the second shell 12 and the base 23.

[0116] Optionally, refer to Fig. 9 and Fig.11 , the number of the first slide grooves 111 is at least two.
[0117] Specifically, if Fig. 9 and Fig.11 As shown, the first slide groove 111 can be designed as a rectangular slide groove, a V-shaped slide groove, an arc-shaped slide groove, a square slide groove, an arc-shaped slide groove or a trapezoidal slide groove. The number of the first slide grooves 111 is at least two. The embodiment of the present application designs two first slide grooves 111 in the same direction, one of which is a rectangular slide groove and the other is a V-shaped slide groove. Among them, the V-shaped slide groove has a better fixing effect on the first sliding part 232, and the rectangular slide groove is convenient for adjusting the position of the first sliding part 232 during the assembly process. Therefore, a design combining the V-shaped slide groove and the rectangular slide groove is adopted to avoid the first sliding part 232 from over-positioning during the assembly process, resulting in assembly failure, or causing jamming and stagnation during operation, thereby ensuring that the system runs smoothly and reliably.
[0118] Optionally, refer to Fig.16 The fixed component 1 also includes a guide rod 13; the guide rod 13 is fixed to the fixed component 1, the transmission mechanism 2 is provided with a sliding sleeve 24, the guide rod 13 is passed through the sliding sleeve 24, and the transmission mechanism 2 is slidably connected with the fixed component 1 through the sliding sleeve 24.
[0119] Specifically, the guide rod and the slider can be assembled to replace the slide groove structure. The guide rod 13 is fixed to the inner side of the fixed component 1, and can be fixed to the inner side of the first shell 11 or the second shell 12.

[0121] Specifically, if Fig.15 As shown, the two first slide grooves 111 both extend along the A direction, but the connection between their ends forms an acute angle with the A direction. In this embodiment, the connection line of the ends of the two first slide grooves 111 is parallel to the C direction, that is, the two first slide grooves 111 are staggered in the installation direction, so that the overall structure of the linkage device is compact, and the bracket 3 can avoid the instrument panel operation button while turning left and right. In addition, the force arms from the two first slide grooves 111 to the display screen can be made equal in length to ensure the stability of the horizontal deflection movement.
[0122] In some embodiments, Figure 7 , Fig. 9 , Fig.12 and Fig.15 As shown, the second slide groove 121 extends in the direction B, and the first slide groove 111 extends in the direction A. In the initial case, Fig. 9 As shown, the first sliding portion 232 is located at the upper limit position of the first sliding groove 111. Fig.15 As shown in FIG. 2 , the second sliding portion 2131 is located in the middle of the second sliding groove 121. When the driving mechanism 4 drives the transmission shaft 46 to rotate, the first transmission tooth 211 meshes with the second transmission tooth 212. Fig.12 As shown, the support 3 is driven to rotate horizontally in the direction a or in the direction opposite to the direction a. At the same time, the transmission shaft 46 drives the transmission arm 213 to swing, as shown in FIG. Fig.15 c or Fig.15 As shown in a, the second sliding part 2131 at the other end of the transmission arm 213 slides along the positive B direction or the negative B direction to the extreme position on the second slide slot 121. The first sliding part 232 slides from the upper extreme position of the first slide slot 111 along the positive A direction to the lower extreme position. The bracket 3 drives the display screen toward the co-pilot position to avoid the main driving position. If the motor rotates in the reverse direction, the second sliding part 2131 slides from the extreme position at one end along the negative B direction or the positive B direction to the middle position on the second slide slot 121, and then slides to the extreme position at the other end.
[0123] Optionally, refer to Fig.13The driving mechanism 4 includes a first driving motor 41, a worm gear assembly 42, a box 43 and a transmission shaft 46; the worm gear assembly 42 is connected between the first driving motor 41 and the transmission shaft 46, the first driving motor 41 and the worm gear assembly 42 are at least partially fixed in the box 43, and the box 43 is fixed in the transmission mechanism 2; the first driving motor 41 drives the transmission shaft 46 to rotate through the worm gear assembly 42, so that the transmission mechanism 2 rotates relative to the bracket 3, and drives the transmission mechanism 2 to slide along the first direction relative to the fixed component 1.
[0124] Specifically, if Fig.13 As shown, the first drive motor 41 and the worm gear assembly 42 are at least partially fixed in the box body 43, and the box body 43 is fixedly connected to the transmission mechanism 2. In this embodiment, the box body 43 is fixedly installed in the base 23. The box body 43 is formed by the upper cover 431 of the box body and the lower cover 432 of the box body. The worm gear assembly 42 includes a first worm 421, a first gear 422, a second worm 423 and a second gear 424. The first worm 421 is the output shaft of the first drive motor 41, the first worm 421 is meshed with the first gear 422, the second worm 423 is penetrated and fixed to the first gear 422, the second worm 423 is meshed with the second gear 424, and the transmission shaft 46 is fixed on the second gear 424 to drive the transmission shaft 46 to rotate. Because the output motion of the first drive motor 41 is reversed and transmitted to the transmission shaft 46. The first drive motor 41 drives the transmission shaft 46 to rotate through the worm gear assembly 42, so that the base 23 of the transmission mechanism 2 deflects horizontally relative to the bracket 3, and drives the base 23 of the transmission mechanism 2 to slide and avoid relative to the fixing assembly 1 along the first direction.
[0125] Optionally, refer to Fig.14 The driving mechanism 4 includes a second driving motor 44, a composite transmission component 45 and a transmission shaft 46; the input end of the composite transmission component 45 is connected to the second driving motor 44, and the output end is connected to the transmission mechanism 2; the second driving motor 44 drives the transmission mechanism 2 to slide relative to the fixed component 1 along the first direction through the composite transmission component 45, while the transmission mechanism 2 drives the transmission shaft 46 to rotate, so that the bracket 3 rotates relative to the transmission mechanism 2.

The composite transmission assembly 45 includes a third worm 451, a third gear 452 and a screw 453. The third gear 452 is meshed with the output shaft of the second drive motor 44, namely the third worm 451, and is fixed to one end of the screw 453, and the other end of the screw 453 is fixedly connected to the base 23 of the transmission mechanism 2. Therefore, under the drive of the second drive motor 44, the base 23 moves in a straight line, and the second sliding portion 2131 of the transmission arm 213 is constrained by the second slide groove 121, so that the transmission arm 213 swings. Different from the driving mode of the combination of the first drive motor 41 and the worm gear assembly 42 mentioned above, in this embodiment, the second drive motor 44 drives the base 23 of the transmission mechanism 2 to slide and avoid relative to the fixed assembly 1 in the first direction through the composite transmission assembly 45, and the transmission arm 213 swings accordingly, driving the transmission shaft 46 to rotate, so that the bracket 3 rotates horizontally relative to the base 23 of the transmission mechanism 2.
