Description

Technical Field

[0001] This utility model belongs to the field of vehicle electronic technology, and specifically relates to a tilting and pitching motion device for a vehicle display screen. Background Technology

[0002] With the development of technology, more and more new energy multi-functional vehicles have emerged in the automotive market, and people's demands for the comfort and functionality of cars are also increasing. The appearance of the front-row center console screen has once sparked enthusiastic praise and love, leading to the demand from front-seat passengers for the orientation of the center console screen, which can be tilted left or right to allow the driver and front passenger to view it separately.

[0003] Currently, most front-row center console screens on the market can tilt left and right to meet the needs of the driver and front passenger. However, due to the different heights of different people, the viewing angle is different. Simply tilting the screen left and right can make it difficult for users to see the screen clearly, affecting the user experience and comfort. Therefore, simply tilting left and right can no longer fully meet the viewing needs of different users. Utility Model Content

[0004] In view of this, the present invention provides a vehicle-mounted display screen tilt and pitch motion device to solve the problems existing in the prior art.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] A vehicle-mounted display screen tilting and pitching motion device includes: a base; a screen bracket, the screen bracket having a slide rail and a first ball joint connector, two sliders slidably mounted in the slide rail, each slider having a second ball joint connector mounted on it; two tilting assemblies, each tilting assembly including a drive motor and a ball joint push rod, the drive motor driving the ball joint push rod to move along its own axis, the ball joint end of each ball joint push rod being connected to a second ball joint connector; and a ball joint strut, the ball joint end of the ball joint strut being connected to the first ball joint connector, the other end being rotatably mounted on the base.

[0007] In the above scheme, the screen bracket is used to mount the display screen. The slide rail and the first ball joint connector are located on the back of the screen bracket. The first ball joint connector is located below the slide rail. Two oscillating components are arranged in parallel. The drive motor can drive the ball joint push rod to reciprocate along its own axial direction. Since the ball end of the ball joint push rod is connected to the second ball joint connector mounted on the slider, when the ball joint push rod moves along its own axial direction, the ball end can divide the axial force, generating a component force along the slide rail direction, thereby causing the slider to move along the slide rail direction. By controlling the two ball joint push rods to move different distances through the two drive motors, the screen bracket... The system enables left and right tilting. When the screen bracket tilts, the ball joint strut below supports and restricts the screen bracket, allowing it to tilt up and down simultaneously, making the orientation angle of the display more flexible. In addition, when the ball joint push rod drives the slider to move within the slide rail, the slider generates a force that resists its movement between the contact surfaces of the slide rail, thus providing damping force to the screen bracket, making the movement of the display smoother and reducing swaying. At the same time, it also provides holding force when the screen bracket and display stop moving, allowing the display to be stably maintained at a certain angle, enhancing stability.

[0008] In one example of this utility model, both the first ball joint connector and the second ball joint connector have spherical grooves inside.

[0009] In the above scheme, the spherical groove is used to cooperate with the ball head end of the ball head push rod and the ball head support rod to form a ball hinge structure. The ball hinge structure can provide flexible multi-degree-of-freedom movement to realize the yaw and pitch movement of the screen bracket and avoid interference.

[0010] In one example of this utility model, the oscillation assembly further includes a lead screw, which includes a lead screw and a lead screw nut. The drive motor is used to drive the lead screw to rotate, and the ball-end push rod is connected to the lead screw nut.

[0011] In the above scheme, the lead screw and the ball-end push rod are set on the same axis. The lead screw is driven to rotate by the drive motor, so that the lead screw nut on the lead screw moves on the lead screw, thereby driving the ball-end push rod to move along the axial direction of the lead screw.

[0012] In one example of this utility model, the output end of the drive motor is connected to a worm gear, and a worm wheel that cooperates with the worm gear is sleeved on the lead screw.

[0013] In the above scheme, the worm gear and the lead screw are fixedly installed and cannot rotate relative to each other. The worm and the worm gear mesh with each other, and the drive motor drives the worm to rotate, which in turn drives the lead screw connected to it to rotate.

[0014] In one example of this utility model, the lead screw includes a threaded portion and a fixed portion, and the worm gear is sleeved on the fixed portion and has an interference fit with the fixed portion.

[0015] In the above scheme, the nut is installed on the threaded part, and the worm gear is interference-fitted onto the fixed part so that the worm gear can drive the lead screw to rotate together when it rotates.

[0016] In one example of this utility model, the lead screw is slidably inserted through the end of the ball-head push rod away from the ball-head end.

[0017] In the above scheme, the lead screw slides through the end of the ball head pusher, and a part of the lead screw is located inside the ball head pusher to make the overall structure more compact.

[0018] In one example of this utility model, the yaw assembly further includes a housing for accommodating the lead screw and the ball-end pusher, the ball-end pusher being slidably disposed within the housing, and the ball-end end of the ball-end pusher being located outside the housing.

[0019] In the above scheme, the lead screw and ball head push rod, except for the ball head end, are housed inside the housing. The housing is used to support and install the ball head push rod and can also provide a certain degree of protection.

[0020] In one example of this utility model, a hinge connector is connected to the end of the ball joint strut away from the ball joint, and the ball joint strut strut is rotatably connected to the base through the hinge connector.

[0021] In the above solution, the hinge connector is hinged to the base, and the ball joint strut is rotatably connected to the base through the hinge connector to achieve the up and down tilting movement of the display screen.

[0022] In one example of this utility model, the second ball joint connector is provided with a mounting hole, and the slider is provided with a hole that mates with the mounting hole.

[0023] In the above solution, the second ball joint connector can be detachably installed on the slider using screws or other connecting parts through the mounting holes, so as to facilitate disassembly and maintenance.

[0024] Compared with the prior art, the beneficial effects of this application are as follows:

[0025] This utility model uses two ball-head push rods to achieve left and right tilting of the screen bracket. At the same time, it also has a rotatable ball-head support rod to support and adjust the bottom of the screen bracket, so that the screen bracket can achieve both left and right tilting and up and down tilting. This makes the orientation angle of the display screen more flexible, more practical, and can meet the viewing needs of more users.

[0026] This utility model is equipped with a slider and a slide rail. The force between the slider and the slide rail provides damping force for the screen bracket, making the movement of the display screen more stable and reducing shaking. At the same time, it can also provide holding force when the screen bracket and the display screen stop moving, so that the display screen can be held stably at a certain angle, enhancing stability and improving user comfort.

Detailed Implementation

[0037] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0038] Please refer to Figures 1 to 7 In a preferred embodiment, a vehicle-mounted display screen tilting and pitching motion device is provided, comprising a base 1, a screen bracket 2, two tilting components 3, and a ball joint strut 4. The screen bracket 2 is provided with a slide rail 21 and a first ball joint connector 22. Two sliders 23 are slidably installed within the slide rail 21, and each slider 23 is equipped with a second ball joint connector 24. The tilting components 3 include a drive motor 31 and a ball joint push rod 32. The drive motor 31 drives the ball joint push rod 32 to move along its own axial direction. The ball joint end 32a of each ball joint push rod 32 is connected to a second ball joint connector 24. The ball joint strut 4 has its ball joint end connected to the first ball joint connector 22, and its other end rotatably mounted on the base 1.

[0039] It should be noted that both the ball-head push rod 32 and the ball-head strut 4 are provided with ball-head ends in a spherical structure, and respectively form a ball-hinged structure with the first ball-head connector 22 and the second ball-head connector 24. The ball-hinged structure is relatively common in the prior art, and its specific motion principle and structure will not be described in detail here.

[0040] Specifically, the screen bracket 2 is used to mount the display screen (not shown in the figure). The slide rail 21 and the first ball joint connector 22 are located on the back of the screen bracket 2 (i.e., the side away from the display screen). The first ball joint connector 22 is located below the slide rail 21. Two oscillating components 3 are arranged in parallel. The drive motor 31 can drive the ball joint push rod 32 to reciprocate along its own axial direction. Since the ball end 32a of the ball joint push rod 32 is connected to the second ball joint connector 24 installed on the slider 23, when the ball joint push rod 32 moves along its own axial direction, the ball end 32a can divide the axial force, generating a component force along the direction of the slide rail 21, thereby causing the slider 23 to move along the direction of the slide rail 21. The two ball joint push rods are controlled by the two drive motors 31. 32 moves different distances, allowing the screen bracket 2 to tilt left and right. When the screen bracket 2 tilts, the ball joint strut 4 below supports and restricts the screen bracket 2, allowing it to tilt up and down while tilting, making the orientation angle of the display screen more flexible and practical. In addition, when the ball joint strut 32 drives the slider 23 to move within the slide rail 21, the slider 23 generates a force that resists its movement between the contact surfaces of the slide rail 21, thus providing damping force for the screen bracket 2, making the movement of the display screen smoother and reducing sway. At the same time, it also provides holding force when the screen bracket 2 and the display screen stop moving, allowing the display screen to be held stably at a certain angle, enhancing stability.

[0041] It is worth mentioning that the tilting motion mentioned above refers to the screen tilting downwards or upwards, similar to the effect of looking down or looking up.

[0042] Preferably, the drive motor 31 is a motor, which is small in size and can make the overall structure more compact.

[0043] Please refer to Figure 3 and Figure 5 The first ball joint connector 22 and the second ball joint connector 24 are both provided with spherical grooves inside. The spherical grooves are used to cooperate with the ball joint ends of the ball joint push rod 32 and the ball joint support rod 4, so that the first ball joint connector 22 and the second ball joint connector 24 can rotate around the center of the ball joint end to form a ball hinge structure. The ball hinge structure can provide flexible multi-degree-of-freedom movement to realize the yaw and pitch movement of the screen bracket 2 and avoid interference.

[0044] Please refer to Figure 2 and Figure 5 The yaw assembly 3 also includes a lead screw 33, which includes a lead screw 331 and a lead screw nut 332. A drive motor 31 is used to drive the lead screw 331 to rotate. A ball head push rod 32 is connected to the lead screw nut 332. The lead screw 331 and the ball head push rod 32 are arranged coaxially. By driving the lead screw 331 to rotate through the drive motor 31, the lead screw nut 332 on the lead screw 331 moves on the lead screw 331, thereby driving the ball head push rod 32 to move along the axial direction of the lead screw 331.

[0045] Furthermore, a worm gear 311 is connected to the output end of the drive motor 31, and a worm wheel 34 that mates with the worm gear 311 is sleeved on the lead screw 331. The worm wheel 34 and the lead screw 331 are fixedly installed and cannot rotate relative to each other. The drive motor 31 drives the worm gear 311 to rotate, which in turn causes the worm wheel 34 to drive the lead screw 331 connected to it to rotate. The transmission through the worm wheel 34 and the worm gear 311 is highly stable and has a self-locking function to prevent accidental reverse rotation from damaging the device, thus enhancing reliability.

[0046] The lead screw 331 includes a threaded part 3311 and a fixed part 3312. The lead screw nut 332 is installed on the threaded part 3311, and the worm gear 34 is sleeved on the fixed part 3312 and has an interference fit with the fixed part 3312, so that when the worm gear 34 rotates, it can drive the lead screw 331 to rotate together.

[0047] Preferably, the fixing part 3312 has a flat position feature to ensure a stable connection and prevent relative rotation.

[0048] Please refer to Figure 2 and Figure 5The lead screw 331 is slidably inserted through the end of the ball head push rod 32 away from the ball head end 32a, so that a part of the lead screw 331 can be located inside the ball head push rod 32, so that the overall structure is more compact and the volume is reduced.

[0049] Please refer to Figures 1 to 5 The yaw assembly 3 also includes a housing 35 for accommodating the lead screw 33 and the ball head push rod 32. The housing 35 is mounted on the base 1. The interior of the housing 35 is hollow. The ball head push rod 32 slides through the end of the housing 35. The ball head end 32a of the ball head push rod 32 is located outside the housing 35. The housing 35 is used to support and install the ball head push rod 32 and can also play a certain protective role.

[0050] Preferably, the drive motor 31 is mounted on the top of the housing 35, and the output end of the drive motor 31 extends into the housing 35, thereby driving the internal worm gear 34 to rotate.

[0051] Please refer to Figure 4 The ball joint strut 4 is connected to a hinge connector 41 at one end away from the ball joint. The base 1 is provided with a mounting groove 11, and two limiting blocks 12 are spaced apart in the mounting groove 11. A rotating shaft (not shown in the figure) is installed between the two limiting blocks 12. The hinge connector 41 is rotatably mounted on the rotating shaft, and the two sides of the hinge connector 41 are limited by the limiting blocks 12, so that the ball joint strut 4 and the base 1 form a rotatable connection. Because the screen bracket has a certain initial tilt angle (i.e., it is not in a vertical state), when the screen bracket 2 swings left and right, the screen bracket 2 will exert force on the ball joint 4, causing the ball joint 4 to rotate around the rotating joint of the hinge connector 41. This causes the lower side of the screen bracket 2 to be raised or lowered by the ball joint 4. At this time, the position of the bottom of the screen bracket 2 in the horizontal direction changes (since the length of the ball joint 4 is fixed, the ball end of the ball joint 4 is the farthest from the base in the horizontal direction in the initial state). The screen bracket 2 will then tilt up or down under the influence of the ball joint 4, so that the display screen can tilt while swinging, so as to have more flexible angles and meet the viewing needs of different users.

[0052] Understandably, in actual use, the length of the ball head strut 4 can be adjusted according to actual needs to meet different usage scenarios and required deflection angles.

[0053] Please refer to Figure 3 and Figure 5 The second ball joint connector 24 is provided with a mounting hole 241, and the slider 23 is provided with a hole that matches the mounting hole 241. Through the mounting hole 241, the second ball joint connector 24 can be detachably installed on the slider 23 using screws or other connecting parts for disassembly and maintenance.

[0054] The following diagram illustrates the different motion states of the screen bracket 2. For ease of understanding, the direction of the axis of the ball head push rod 32 is defined as the X direction. From the front of the screen bracket 2, the two oscillating components 3 are the left oscillating component M and the right oscillating component N.

[0055] It should be noted that when the screen bracket 2 is subjected to a force along the X direction under the action of the ball joint push rod 32, since the lower part of the screen bracket 2 is connected and fixed by the ball joint support rod 4, the swaying of the screen bracket 2 will drive the ball joint support rod 4 to rotate, causing the ball joint end of the ball joint support rod 4 to rise or fall. Subsequently, under the restraint of the ball joint support rod 4, the lower height of the screen bracket 2 changes, and the screen bracket 2 will exhibit a swaying and tilting motion to facilitate user viewing. When the screen bracket 2 is tilted upward, it is especially suitable for taller users to view, in order to meet the viewing needs of different customers and improve the user experience and comfort. When the screen bracket 2 is tilted downward, it is suitable for situations where the display screen is in a high position, such as when the display screen is located on the roof of a car, so that users below can view it.

[0056] Reference Figure 6 The initial position of screen bracket 2 is A. When the ball joint push rod 32 of the left yaw component M moves backward in the X direction and the ball joint push rod 32 of the right yaw component N does not move, the lower ball joint support rod 4 rotates under the force of screen bracket 2, raising the bottom of screen bracket 2. At this time, screen bracket 2 will move to... Figure 6 Position B in the image shows a leftward tilt and upward tilt (upward tilt). Similarly, when the ball joint push rod 32 of the left tilt component M moves forward in the X direction and the ball joint push rod 32 of the right tilt component N does not move, the screen bracket 2 will show a rightward tilt and downward tilt (downward tilt).

[0057] Reference Figure 7 The initial position of screen bracket 2 is A. When the ball joint push rod 32 of the right yaw component N moves backward in the X direction and the ball joint push rod 32 of the left yaw component M does not move, the lower ball joint support rod 4 rotates under the force of screen bracket 2, raising the bottom of screen bracket 2. At this time, screen bracket 2 will move to... Figure 7 Position C in the image shows a rightward tilt and upward tilt. Similarly, when the ball joint push rod 32 of the right tilt component N moves forward in the X direction and the ball joint push rod 32 of the left tilt component M does not move, the screen bracket 2 will show a leftward tilt and downward tilt.

[0058] It is understandable that when the ball-head push rods 32 of the left yaw component M and the right yaw component N move backward the same distance in the X direction at the same time, under the constraint of the lower ball-head support rod 4, the screen bracket 2 will be in a centered and tilted upward (not shown in the figure).

[0059] For ease of viewing, the display screen and screen bracket 2 are usually tilted upwards in the initial state. When the ball head push rods 32 of the left tilt component M and the right tilt component N move forward the same distance in the X direction at the same time, the screen bracket 2 becomes vertical under the constraint of the lower ball head support rod 4. In the case of strong light, making the display screen vertical can avoid reflection and ensure that the user can see the display screen clearly. If the two ball head push rods 32 continue to move forward, the display screen will be centered and tilted downwards (not shown in the figure).
