Abstract
Description
Technical Field
[0001] This invention relates to the field of in-vehicle central control screen technology, specifically to a fully electric rotating screen mechanism for automobiles. Background Technology
[0002] The central control screen in a car is commonly used to display a variety of information, including audio and video, navigation, and communication data. Through human-machine interaction, it can also be used to control vehicle functions, providing significant convenience for the driver. Traditionally, the central control screen is fixed directly to the dashboard, and its fixed angle can hinder the driver and front passenger from reading and operating the information displayed. Some cars use brackets to fix the central control screen, allowing for some adjustment, but this is limited to extension, retraction, and horizontal / vertical movement. It lacks the full-range rotation (up, down, left, and right) possible in a fully electric configuration, and cannot be manually adjusted to the desired position when the power is off. In certain situations, this still affects the driver and front passenger's ability to read and operate the information displayed on the screen. Summary of the Invention
[0003] To solve the technical problem of the difficulty in fully electric omnidirectional rotation of the central control screen, this invention provides a fully electric rotating screen mechanism for automobiles.
[0004] The technical solution is as follows:
[0005] The key features of the fully electric rotating screen mechanism for automobiles are that it includes a tilting rotation mechanism and a drive mechanism. The outer side of the upper end of the outer ring of the tilting rotation mechanism is provided with a snap-fit groove for snapping the screen connection bracket. The top of the screen connection bracket is fixedly connected to the central control screen. The upper end of the rotating shaft of the tilting rotation mechanism is connected to the outer ring through an inner ring. The inner ring is evenly provided with four connecting parts around its circumference. The two opposite connecting parts are respectively connected to the rotating shaft and the outer ring.
[0006] Preferably, a joint ball is sleeved on the shaft below the outer ring. The joint ball is movably connected to the connecting rod fixing flange through the swing bearing. The top of the connecting rod fixing flange abuts against the outer ring. The connecting rod fixing flange is provided with a through hole and a lug. The guide rod passes through the through hole and connects the graphite copper plate and the swing bearing. The lug is connected to a stainless steel pull rod, and the other end of the stainless steel pull rod is connected to the drive mechanism.
[0007] Preferably, the drive mechanism is arranged around the lower end of the rotating shaft, wherein the motor shafts of the first yaw motor and the second yaw motor are each provided with a motor rocker arm, the motor rocker arm is connected to the connecting rod fixing flange by a stainless steel tie rod, the motor shaft of the rotary motor is provided with a drive gear, the drive gear meshes with the driven gear, and the driven gear is sleeved on the lower end of the rotating shaft.
[0008] The above structure enables omnidirectional rotation and fully electric control of the central control screen. The motor controlling the screen rotation drives the drive gear, which in turn drives the driven gear and the rotating shaft. The rotating shaft, through an inner ring, drives an outer ring and the screen connection bracket that is fastened to the outer ring, thus achieving the rotation of the central control screen. It can rotate in both clockwise and counterclockwise directions. The motor drives a motor rocker arm to pull a stainless steel rod, which in turn pulls the connecting rod fixing flange to tilt up, down, left, and right, achieving the tilting of the central control screen.
[0009] Preferably, the drive shaft is disposed inside the sheet metal housing, the rotating shaft is connected to the sheet metal housing via a rotating shaft copper sleeve, and a retaining ring is provided between the rotating shaft copper sleeve and the rotating shaft for fixing the rotating shaft.
[0010] Preferably, the rotary motor is fixed on the rotating shaft motor mounting sheet metal, and the bottom of the rotating shaft motor mounting sheet metal is fixed to the base plate of the sheet metal housing by screws; the first yaw motor and the second yaw motor are mounted on the tilt motor mounting sheet metal, and the tilt motor mounting sheet metal is fixed to the base plate of the sheet metal housing by screws.
[0011] With the above structure, all motors are installed inside the sheet metal housing. The motors, inside the sheet metal housing, control the rotation, tilting, and vertical movement of the central control screen via a rotating shaft and a stainless steel tie rod, reducing the possibility of physical wear and tear on the components.
[0012] Preferably, the connection between the rotating shaft and the inner ring is provided with a protruding rotating shaft connection end, the connection between the inner ring and the outer ring is provided with a protruding inner ring connection end, and pin holes are provided on both sides of the rotating shaft connection end, the inner ring connection end and the outer ring.
[0013] Preferably, the same pin is inserted into the corresponding pin hole of the rotating shaft connecting end and the rotating shaft to connect the rotating shaft and the inner ring. The same pin is inserted into the corresponding pin hole of the inner ring connecting end and the outer ring to connect the inner ring and the outer ring. The line connecting the two rotating shaft connecting ends 2 and the line connecting the two inner ring connecting ends form a cross shape.
[0014] Preferably, each of the pin holes is provided with a bushing, and the pin passes through the bushing.
[0015] Preferably, the joint ball has a spherical structure and is fixedly connected to the rotating shaft. The inner side of the eccentric bearing is recessed and abuts against the joint ball. The top of the connecting rod fixing flange protrudes inward by a ring, and the protruding part is placed at the top of the eccentric bearing.
[0016] With the above structure, the inner ring realizes the multi-directional wobble function of the cross bearing. By fitting the wobble bearing on the joint ball of the spherical structure, it can not only realize the multi-directional tilting of the wobble structure, but also prevent the wobble structure from falling off.
[0017] Preferably, the graphite copper plate is embedded with graphite powder and is fixed in a guide groove. The bottom end of the guide groove is fixed to the cover plate of the sheet metal housing by screws. A guide rod is provided between the graphite copper plates. One end of the guide rod is inserted into the U-shaped groove of the graphite copper plate, and the other end abuts against the eccentric bearing through the through hole of the connecting rod fixing flange, which restricts the rotation and swaying of the connecting rod fixing flange, so that the connecting rod fixing flange only tilts up, down, left and right.
[0018] With the above structure, the graphite powder in the graphite copper plate has a good lubricating effect, which can reduce the friction of the guide rod, making the sway of the automotive all-electric rotating screen mechanism smoother and reducing the noise of the mechanism operation; at the same time, the guide rod can also limit the sway angle of the connecting rod fixing flange and set the maximum tilt angle of the central control screen.
[0019] Preferably, small joint bearings are provided inside the support lug and at the front of the motor rocker arm, and the stainless steel tie rod is movably connected to the connecting rod fixing flange and the motor rocker arm through the small joint bearings.
[0020] Using the above structure, the spherical small joint bearing can achieve eccentric rotation, which can adapt to the angle changes generated when the motor drives the screen to tilt up and down or left and right through the stainless steel rod, thus achieving smooth up and down or left and right tilting of the central control screen.
[0021] Compared with existing technologies, the advantages of this invention are: it enables fully electric rotation or tilt control of the central control screen. A servo motor drives the gears of the reduction gearbox to rotate, which in turn moves the lever, achieving control in all directions. The tilt angles in the four directions (up, down, left, and right) are adjustable to a set range, and the screen rotation angle can reach a maximum of 180 degrees. By operating the buttons on the central control screen, operations such as tilting upwards, downwards, left, right, rotating clockwise (portrait to landscape), and rotating counterclockwise (landscape to portrait) can be performed. After the power supply to the motor is stopped, the central control screen can be manually rotated or tilted to any position. The mechanism relies on the self-locking resistance provided by the reduction gearbox inside the motor to prevent the screen from rotating due to vehicle vibration or gravity.
