[0002] As an important part of the car audio and video system, the in-vehicle display device has functions such as playing programs, connecting to rear-view radar and lighting. In order to meet the different needs of users, it is usually necessary to adjust its position and angle during use.

DETAILED DESCRIPTION

[0080] 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.

[0081] 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.

[0082] The linkage device, display system and vehicle provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0083] Reference Figure 1 , Figure 2 and Figure 6 The embodiment of the present application provides a linkage device, including a fixed component 1, a first transmission mechanism 2, a second transmission mechanism 3, a first bracket 61 and a second bracket 62; the first transmission mechanism 2 is slidably connected to the fixed component 1, the first transmission mechanism 2 is movably connected to the first bracket 61, and the first bracket 61 can rotate around a first direction relative to the first transmission mechanism 2; the second transmission mechanism 3 is rotatably connected to the second bracket 62 around a second direction; when the first bracket 61 is in a preset state relative to the fixed component 1, while the first bracket 61 rotates relative to the first transmission mechanism 2, the first transmission mechanism 2 slides relative to the fixed component 1 along a preset direction of a third direction; the first bracket 61 and the second bracket 62 are suitable for jointly driving the target object to move.

[0084] Specifically, the linkage device provided in the embodiment of the present application can be used for a display system, a mobile phone mounting bracket or other vehicle-mounted multimedia devices. Figures 1 to 3 As shown, the fixing assembly 1, the first transmission mechanism 2, the first driving mechanism 4, and the first bracket 61 constitute a translation and lateral rotation module. Figure 1 and Figure 6As shown, the second transmission mechanism 3, the second drive mechanism 5 and the second bracket 62 constitute a pitch or rotation motion module. In the translation and lateral rotation module, the fixing component 1 is used to install and fix the vehicle body, and can be connected by screws or other mechanical connections. The first transmission mechanism 2 is slidably connected to the fixing component 1 through a slide groove. The first transmission mechanism 2 is movably connected to the first bracket 61, so that the first bracket 61 is driven by the first transmission mechanism 2 to rotate around the first direction Z relative to the first transmission mechanism 2, that is, horizontally deflect. Therefore, the first drive mechanism 4 drives the first transmission mechanism 2 to move, driving the first bracket 61 to translate relative to the fixing component 1 and deflect horizontally at the same time. As shown Fig.13 As shown, the third direction is direction A. When the first bracket 61 is in a preset state relative to the fixing component 1, also known as the initial state, the first bracket 61 is in a state where no deflection occurs relative to the fixing component 1. Fig.13 As shown in FIG. b, the first bracket 61 is in a state where there is no angular deflection relative to the fixing assembly 1. In this state, the surface of the first bracket 61 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 first bracket 61 are in the center. Fig.13 Figure b changes to Figure a or Figure c, no matter the first bracket 61 deflects to the left or to the right relative to the first transmission mechanism 2, the first transmission mechanism 2 slides along the positive A direction relative to the fixed component 1, that is, slides along the preset direction of the third direction, and the A direction has a branch movement along the C direction, and the C direction is the moving avoidance direction, along the width direction of the vehicle, from the main driver's seat to the co-driver's seat.

[0085] like Figure 1 and Figure 6 As shown, in the pitch or rotation motion module, the second transmission mechanism 3 is rotatably connected to the second bracket 62 around the second direction, and the second direction intersects with the first direction to form a certain angle. In this embodiment, the second direction is orthogonal to the first direction, as shown in FIG. Figure 1 and Figure 3 As shown, the second direction is the X direction or the Y direction. When the second direction is the X direction, the second bracket 62 performs a pitch rotation relative to the second transmission mechanism 3; when the second direction is the Y direction, the second bracket 62 performs a left-right rotation relative to the second transmission mechanism 3. Therefore, driven by the second transmission mechanism 3, the second bracket 62 can perform a pitch rotation or a left-right rotation. However, the operation of the second transmission mechanism 3 and the first transmission mechanism 2 are independent of each other. When the first transmission mechanism 2 and the second transmission mechanism 3 are driven at the same time, the linkage device can output a composite motion of translation, horizontal deflection and pitch, or output a composite motion of translation, horizontal deflection and left-right rotation. The first bracket 61 and the second bracket 62 are suitable for jointly driving the movement of the target object, and the target object includes a display screen, a mobile phone, a stereo or other electronic equipment.

[0086] The linkage device provided in the embodiment of the present application can output a compound motion of translation avoidance, horizontal deflection and pitch, or a compound motion of translation avoidance, horizontal deflection and left and right rotation, under the simultaneous drive of the first transmission mechanism and the second transmission mechanism, so that the display screen can move and dock within a preset angle range, meet the different usage needs of users, avoid interference with vehicle body parts, and improve convenience.

[0087] Optionally, refer to Figure 3 to Figure 4 , further comprising a first driving mechanism 4 and a second driving mechanism 5; the first driving mechanism 4 is connected to the first transmission mechanism 2, and the second driving mechanism 5 is connected to the second transmission mechanism 3.

[0088] Specifically, the drive mechanism may be in the form of, but not limited to, hydraulic drive, pneumatic drive or motor drive. The first drive mechanism 4 is connected to the first transmission mechanism 2 and outputs power to the first transmission mechanism 2. The first drive mechanism 4 may be fixed to the fixed component 1 and move with the overall linkage device, or fixed to the vehicle body and not move with the overall linkage device. While the first drive mechanism 4 drives the first transmission mechanism 2 to slide relative to the fixed component 1, the first bracket 61 rotates relative to the first transmission mechanism 2 about the first direction Z. Figure 6 , Fig.14 and Fig.15 As shown, the second drive mechanism 5 is fixedly connected to the first bracket 61, and the second drive mechanism 5 is connected to the second transmission mechanism 3, and the power output by the second drive mechanism 5 is transmitted to the second bracket 62, so that the second bracket 62 rotates around the second direction relative to the second transmission mechanism 3 to achieve pitch motion or left and right rotation motion.

[0090] Specifically, if Figures 1 to 3 As shown, the first driving mechanism 4 is connected to the transmission component 21 and / or the base 22 to output power to the transmission component 21. When the first driving mechanism 4 is located outside the linkage device, it is movably connected to the base 22; when the first driving mechanism 4 is connected to the transmission component 21, it moves with the movement of the linkage device. The fixed component 1 is provided with a first slide groove 131 and a second slide groove 132. The transmission component 21 is slidably connected to the first slide groove 131, and the base 22 is slidably connected to the second slide groove 132, and a certain angle is formed between the first slide groove 131 and the second slide groove 132. Fig.13As shown, the first slide slot 131 is along the fourth direction B, and the second slide slot 132 is along the third direction A. A certain angle is formed between the first slide slot 131 and the second slide slot 132, and the angle can be 60°, 70°, 80° or 90°. In this embodiment, the first slide slot 131 and the second slide slot 132 are arranged to be perpendicular to each other, that is, the A direction and the B direction are perpendicular to each other. The transmission component 21 is connected with the first bracket 61 by gears, and the first bracket 61 is connected with the base 22 by rotation through a flange or a rotating shaft. Under the drive of the first driving mechanism 4, on the one hand, the transmission component 21 realizes relative sliding between the first slide slot 131 and the fixed component 1; on the other hand, the transmission component 21 drives the first bracket 61 to rotate relative to the base 22 around the vertical direction, so that the first bracket 61 forms a composite movement of translation and horizontal deflection, and at the same time drives the third bracket 63 to perform a composite movement of translation and horizontal deflection.

[0093] Specifically, if Figures 2 to 3 As shown, the transmission assembly 21 includes a first transmission tooth 211, a second transmission tooth 212 and a transmission arm 213, and the output shaft 44 outputs the power of the first driving mechanism 4 to the transmission assembly 21.

The second transmission tooth 212 is a rack, which can be in a bar shape or an arc shape, meshing and connected with the first transmission tooth 211, and the second transmission tooth 212 is fixed to the first bracket 61 by screws. The transmission arm 213 is a crank, one end of which is connected to the output shaft 44, and the other end is slidably connected to the first slide groove 131. When the output shaft 44 is driven to rotate, on the one hand, it drives the transmission arm 213 to swing, so that the small shaft on the other end of the transmission arm 213 slides along the first slide slot 131, and the torque transmitted by the transmission arm 213 is converted into a thrust acting on the first slide slot 131, so as to drive the transmission component 21 to perform a linear translation motion relative to the fixed component 1; on the other hand, the first bracket 61 is driven to rotate around the vertical direction relative to the base 22, i.e., horizontal deflection, through the first transmission teeth 211 and the second transmission teeth 212.

[0098] Specifically, if Figure 3 As shown, the first fixed shell 11 and the second fixed shell 12 are snap-fitted and assembled to form a fixed assembly 1, and the connection methods of the first fixed shell 11 and the second fixed shell 12 include but are not limited to snap-fit, screw connection, riveting, magnetic attraction or other methods that can be easily thought of by those skilled in the art.

The cross-section of the second slide groove 132 can be one of a rectangular V-shape, an arc shape, a square shape, an arc shape or a trapezoidal shape. Among them, the V-shaped slide groove has a better fixing effect on the slider, and the square slide groove is convenient for adjusting the position of the slider during assembly. The other end of the transmission arm 213 is slidably connected to the first slide groove 131. The base 22 is slidably connected to the second slide slot 132. Driven by the output shaft 44, the transmission arm 213 swings, and the small shaft on the other end slides along the first slide slot 131 relative to the first fixed shell 11, and at the same time, the base 22 slides along the second slide slot 132 relative to the second fixed shell 12.

In this embodiment, the first slide groove 131 and the second slide groove 132 are arranged to be perpendicular to each other, that is, the A direction and the B direction are perpendicular to each other.

[0103] Optionally, refer to Figure 7 and Fig.15 The second driving mechanism 5 includes a shell component 51 and a second driving component 52; the shell component 51 is fixedly connected to the first bracket 61, the second driving component 52 is fixed in the shell component 51, and the second driving component 52 is connected to the second transmission mechanism 3.

[0104] Specifically, if Figure 7 and Fig.15 As shown, the second drive assembly 52 is assembled inside the housing assembly 51, and one side of the housing assembly 51 has an opening for extending the second bracket 62. The second drive assembly 52 is composed of a motor and a gear-worm linkage structure. When the motor receives an operation command and operates, the torque is transmitted to the power output end through the gear-worm linkage structure. The function of the gear-worm linkage structure is to change the rotation direction to facilitate the arrangement of the motor. When the pitch motion is realized, the second drive assembly 52 outputs a linear motion to the second transmission mechanism 3; when the left and right rotation motion is realized, the second drive assembly 52 outputs a rotation around the second direction to the second transmission mechanism 3.

[0105] Optionally, refer to Figure 6 and Figure 7 The second transmission mechanism 3 includes a first connecting member 31 and a second connecting member 32; the first connecting member 31 is slidably connected to the shell assembly 51, the second connecting member 32 is rotatably connected to the first connecting member 31 around the second direction, the second bracket 62 is rotatably connected to the second connecting member 32 around the second direction, and the first connecting member 31 is connected to the second driving assembly 52.

[0106] Specifically, if Figure 6 and Figure 7 As shown, in the pitch motion module, the first connecting member 31 is a threaded connecting member, and the second connecting member 32 is a connecting bracket. The first connecting member 31 is threadedly connected to the power output shaft of the second drive assembly 52, one side of the second connecting member 32 is hinged to the second bracket 62 to achieve relative rotation around the horizontal direction X, and the other side is hinged to the first connecting member 31 to achieve relative rotation around the horizontal direction X. When the second drive assembly 52 is running, and its power output shaft lead screw rotates, the first connecting member 31 transmits the linear motion output by the second drive assembly 52 to the second connecting member 32 by means of the threaded connection, and the first connecting member 31 performs linear motion in the housing assembly 51. Then the second connecting member 32 rotates around the horizontal direction relative to the first connecting member 31, and the second bracket 62 rotates around the horizontal direction relative to the second connecting member 32 to achieve pitch motion.

[0107] Specifically, if Figures 6 to 8 As shown, the housing assembly 51 is composed of an upper housing 511 and a lower housing 512, and the upper housing 511 and the lower housing 512 are assembled by screw fastening, and the second drive assembly 52 is installed in the lower housing 512. The first connecting member 31 is installed on the screw rod to convert the rotational motion into the linear motion of the first connecting member 31. In order to avoid the first connecting member 31 from being stuck or making noise during the movement, a guide bar is provided in the upper housing 511, and a guide groove 311 is provided on the side of the first connecting member 31. A gasket is added between the guide bar and the guide groove 311 to prevent the guide groove 311 from directly contacting the guide bar and generating excessive noise. After the guide bar and the guide groove 311 are installed in cooperation, they are screwed to the lower housing 512. Therefore, the output shaft screw of the second drive assembly 52 pushes the first connecting member 31 to slide relative to the upper housing 511 along the guide bar of the upper housing 511, thereby driving the second connecting member 32 and the second bracket 62 to rotate in the horizontal direction.

The connecting rod 312 of the first connecting member 31 is clamped between the two first connection parts 321, and the first fastener 33 is penetrated between the connecting rod 312 and the two first connection parts 321 to realize the hinge between the first connecting member 31 and the second connecting member 32. The second bracket 62 is clamped between the two second connection parts 322, and the second fastener 34 is penetrated between the second bracket 62 and the two second connection parts 322 to realize the hinge between the second connecting member 32 and the second bracket 62. Therefore, under the linear push of the connecting rod 312, the second bracket 62 is made to pitch and rotate around the horizontal direction.

[0111] Specifically, if Fig.15As shown, in the rotational motion module, the housing assembly 51 is composed of a front housing 513, a rear housing 514 and a support shell 515. The support shell 515 is used to fix the rotational module and is fixed to the first bracket 61. The second drive assembly 52 includes a second motor 521 and a gear worm 522. The second motor 521 is fixed in the space formed by the front housing 513 and the rear housing 514.

The pipe sleeve 36 is fixedly connected to the support shell 515, and the second bracket 62 is rotatably connected to the pipe sleeve 36 around the second direction Y. Therefore, the second motor 521 drives the third transmission tooth 35, drives the rotating disk to achieve rotational motion, and then drives the display screen to rotate left and right.

[0112] Optionally, refer to Fig.15 The second transmission mechanism 3 also includes a clamping ring 37; the clamping ring 37 is arranged between the pipe sleeve 36 and the second bracket 62, and the pipe sleeve 36 is rotatably connected to the second bracket 62 through the clamping ring 37.

[0119] Specifically, if Figure 3 As shown, the elastic member 7 is a wave spring, which is arranged between the base 22 and the first fixed shell 11, and between the base 22 and the second fixed shell 12. During the assembly process of the first fixed shell 11 and the second fixed shell 12, the elastic member 7 is pressed, and the elastic member 7 relies on its own elastic force to ensure the clearance when the base 22 slides in the second slide groove 132 of the second fixed shell 12, and plays a role of buffering and shock absorption, reducing the noise of the base 22 during the movement, making the movement process more stable.

[0120] Optionally, refer to Fig. 9 and Fig.10 , further comprising a third bracket 63; the first bracket 61 and the second bracket 62 are both connected to the third bracket 63, and the third bracket 63 is suitable for connecting to the display component.

The first bracket 61 is connected to the third bracket 63 by bolts, and a torsion spring is added between the connection structure of the two to facilitate the relative rotation of the first bracket 61 relative to the third bracket 63, thereby ensuring the stability of the display screen 8 during the motion and reducing noise.

[0122] Optionally, refer to Figure 4 and Figure 5 The first driving mechanism 4 includes a first motor 41, a first gear 42 and a worm 43, and the transmission assembly 21 also includes a second gear 216; the second gear 216 is sleeved on the output shaft 44, the motor shaft of the first motor 41 is threadedly connected with the first gear 42, the worm 43 is connected with the first gear 42, the worm 43 is meshed with the second gear 216, and the motor shaft of the first motor 41 has an angle with the output shaft 44.

[0123] Specifically, if Figure 4 and Figure 5As shown, the motor shaft of the first motor 41 is meshed with the first gear 42, and the worm 43 is meshed with the second gear 216. The first gear 42 and the worm 43 are fixedly connected and coaxial, forming a gear and worm assembly. When the first motor 41 receives an operation command, the motor shaft rotates, driving the first gear 42 and the worm 43 to rotate, and the worm 43 transfers the torque to the second gear 216, and the rotation of the second gear 216 drives the output shaft 44 to rotate. There is an angle between the motor shaft and the output shaft 44. In this embodiment, the angle is designed to be 90°, so the motor shaft and the output shaft 44 are perpendicular to each other. By setting the gear and worm assembly, the rotation direction is reversed, which is convenient for the installation and arrangement of the first motor 41.

[0124] Optionally, refer to Figures 11 to 13 , a first mounting position 121, a second mounting position 122, a third mounting position 123 and a fourth mounting position 124 are arranged on the surface of the fixing component 1; a projection of a line connecting the first mounting position 121 and the fourth mounting position 124 on the first plane is parallel to the third direction, and a projection of a line connecting the second mounting position 122 and the third mounting position 123 on the first plane is parallel to the third direction; an acute angle is formed between a projection of a line connecting the first mounting position 121 and the second mounting position 122 on the first plane and the third direction, and / or an acute angle is formed between a projection of a line connecting the fourth mounting position 124 and the third mounting position 123 on the first plane and the third direction.

[0125] Specifically, if Figures 11 to 13 As shown, four mounting positions are provided on the surface of the fixing assembly 1. In this embodiment, four mounting positions are provided on the surface of the second fixing shell 12: a first mounting position 121, a second mounting position 122, a third mounting position 123 and a fourth mounting position 124, which are used to fix the linkage device to the vehicle body. Fig.17 As shown, the top surface of the first fixed shell 11 is defined as the first plane, i.e., the horizontal plane, the second slide groove 132 is along the A direction, i.e., the third direction, the projection of the line between the first mounting position 121 and the fourth mounting position 124 on the first plane is parallel to the third direction, and the projection of the line between the second mounting position 122 and the third mounting position 123 on the first plane is parallel to the third direction. The projection of the line between the first mounting position 121 and the second mounting position 122 on the first plane forms an acute angle with the third direction, and the projection of the line between the fourth mounting position 124 and the third mounting position 123 on the first plane forms an acute angle with the third direction. The C direction is the width direction of the vehicle. Therefore, the figure formed by the projection of the four mounting positions on the first plane is a parallelogram or a trapezoid. Staggered in the length direction and width direction of the vehicle, the torsion resistance and stability of the device are enhanced. Since the first bracket 61 needs to enter and exit the fixed shell obliquely, this staggered installation structure provides sufficient movement space for the first bracket 61.

[0126] Optionally, refer to Figures 11 to 13 , the distance between the first mounting position 121 and the first plane is different from the distance between the first planes of the fourth mounting position 124, and / or the distance between the second mounting position 122 and the first plane is different from the distance between the first planes of the third mounting position 123.

[0127] Specifically, the distance between the mounting position and the first plane represents the vertical height of the mounting position and the position along the height direction of the vehicle. The vertical heights of the first mounting position 121 and the fourth mounting position 124 are different, and the vertical heights of the second mounting position 122 and the third mounting position 123 are different. Therefore, the four mounting positions are staggered in vertical height, further enhancing the torsion resistance and stability.

[0128] The embodiment of the present application further provides a display system, including a display screen and the linkage device described in any one of the above embodiments, wherein the first bracket 61 and the second bracket 62 are used to jointly drive the display screen assembly to move.

[0129] Optionally, the display assembly includes a display screen 8 and a fourth bracket 64; the display screen 8 and the fourth bracket 64 are connected in one piece or in separate pieces.

[0130] Specifically, the first bracket 61 and the second bracket 62 drive the display assembly to realize linear movement, horizontal deflection and pitching composite movement, or linear movement, horizontal deflection and left-right rotation composite movement. The display screen 8 and the fourth bracket 64 can be connected in one piece or fixedly connected in a split manner. This allows the display assembly to move and dock within a preset angle range, meeting different user needs, avoiding interference with vehicle body parts, and improving convenience.
