Detailed Implementation

[0019] To make the above features and advantages of the present invention more readily understood, specific embodiments are described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0020] refer to Figures 1 to 8 An electric rotating device for a display mounting base includes a connecting base 100. A rotating base 200, which is driven to flip up and down by a first electric mechanism, is hinged to the front side of the connecting base. An electric flipping limit mechanism is provided for the rotating base so that the rotating base stops flipping after it has been flipped into place under the drive of the first electric mechanism. A mounting plate 300, which is driven to rotate by a second electric mechanism, is provided to the front side of the rotating base. An electric rotation limit mechanism is provided for the mounting plate so that the mounting plate stops rotating after it has been rotated into place under the drive of the second electric mechanism.

[0021] In this embodiment, in order to enable the connecting seat to be connected to the bracket, the connecting seat includes a fixed seat 101 with a mounting groove on the rear side, a hinge seat 110 is installed on the front side of the fixed seat, and wing plates 116 that turn forward are respectively provided on both sides of the hinge seat. Connecting plates 210 that are hinged to the wing plates are respectively installed on both sides of the rear part of the rotating seat, so as to realize the connection between the connecting seat and the rotating seat.

[0022] In this embodiment, the connecting seat can also be an independent component. For example, the two sides of the connecting seat are respectively provided with a wing plate 116 that turns forward, and the two sides of the rear of the rotating seat are respectively provided with a connecting plate 210 that is hinged to the wing plate. The electric flipping limiting mechanism is provided on one side of the wing plate and the connecting plate, and the first electric mechanism is provided on the other side of the wing plate and the connecting plate.

[0023] In this embodiment, to limit the vertical rotation angle of the rotating seat, the electric rotation limiting mechanism includes a transverse rotating shaft 120. The transverse rotating shaft passes through a connecting plate and a wing plate located on one side. A torsion spring 114 is sleeved on the end of the transverse rotating shaft passing through the wing plate and a rotating baffle 115 is fixed thereon. One end of the torsion spring is connected to the wing plate, and the other end of the torsion spring is connected to the rotating baffle, so that the rotating seat remains in the corresponding position after rotating to the desired position. A transverse bending portion 211 is located on the connecting plate on one side, and an arc-shaped limiting groove 111 for the transverse bending portion to pass through is provided on the wing plate on one side. A rotation upward limiting switch 112 and a rotation downward limiting switch 113 that cooperate with the transverse bending portion are respectively provided on the upper and lower sides of the arc-shaped limiting groove, so that when the transverse bending portion touches the rotation upward limiting switch 412 or the rotation downward limiting switch 413, the first reduction motor stops rotating.

[0024] In this embodiment, to achieve the vertical flipping of the rotating seat, the first electric mechanism includes a first geared motor 221 mounted on the rotating seat. The output end of the first geared motor is driven by a vertically mounted first worm gear 222. A first rotating shaft passes through a wing plate and a connecting plate on the other side. A first worm wheel 140, which meshes with the first worm gear and drives the first rotating shaft to rotate, is installed at one end of the first rotating shaft that provides rotational damping between the first rotating shaft and the connecting plate. The use of a worm gear drive helps reduce transmission errors and has self-locking properties.

[0025] The first pre-tightening component causes the first worm gear to rotate the connecting plate by applying a pre-tightening force. When the sum of the forces applied to the connecting plate exceeds the pre-tightening force (friction) between the connecting plate and the first rotating shaft, the first rotating shaft remains stationary while the connecting plate rotates. For example, when the rotating seat is manually pushed, a force of no more than 50 kN can be applied to it, allowing the rotating seat to rotate while the first rotating shaft remains stationary. Alternatively, if the rotation of the display screen on the mounting plate is obstructed, the first rotating shaft can rotate while the connecting plate remains stationary, preventing damage to the first geared motor and avoiding collisions with personnel.

[0026] In this embodiment, to achieve rotational damping and prevent damage to the first geared motor under overload, the first preload assembly includes a first washer 151 located between the wing plate and the first worm gear on the other side, a first butterfly washer 152 abutting against the outer surface of the first worm gear, and a limiting plate 153 abutting against the outer surface of the first butterfly washer at one end of the first rotating shaft via an internal thread; a second butterfly washer 154 located outside the connecting plate on the other side is sleeved on the other end of the first rotating shaft, and a limiting plate 153 abutting against the outer surface of the first butterfly washer is screwed onto the other end of the first rotating shaft via an external thread. The preload nut 155 abuts against the outer side of the second butterfly-shaped washer. A second washer 156 is also provided between the wing plate and the connecting plate on the other side. Auxiliary washeres are provided between the fourth washer and the connecting plate, and between the third and second butterfly-shaped washers and the connecting plate. The first washer, second washer, first worm gear, first butterfly washer, and second butterfly washer all have matching anti-rotation structures with the first rotating shaft, thereby preventing the third washer, fourth washer, first worm gear, first butterfly washer, and second butterfly washer from rotating on the first rotating shaft. Furthermore, this structure also helps to reduce the force required for manual up-and-down rotation of the rotating seat, and avoids interference with electric rotation.

[0027] In this embodiment, the anti-rotation structure on the first rotating shaft is as follows: an arc-shaped structure is cut off from the upper and lower parts of both sides of the first rotating shaft to form a waist-shaped cross-section, as shown in the first rotating shaft structure diagram; a section of the first rotating shaft has a circular cross-section; the first gasket, the second gasket, the first worm gear, the first butterfly gasket, and the second butterfly gasket each have a waist-shaped hole that mates with the first rotating shaft. The first gasket, the second gasket, the first butterfly gasket, and the second butterfly gasket can be made of POM material to improve wear resistance.

[0028] In this embodiment, to achieve the electric rotation of the mounting base plate, the second electric mechanism includes a second geared motor 231 mounted on the rotating base. The output end of the second geared motor is connected to a vertically mounted second worm gear 232. A second rotating shaft 240 is longitudinally mounted on the rotating base. A second worm wheel 250, meshing with the second worm gear and driving the second rotating shaft, is mounted on the rear side of the rotating base. A rotation limiting plate 260 and a fixing plate 310 are mounted on the front side of the second rotating shaft. The fixing plate is connected to the mounting base plate by bolts. A second preload assembly is also mounted on the second rotating shaft to provide rotational damping between the second rotating shaft and the rotation limiting plate and the fixing plate. The use of a worm gear drive helps reduce transmission errors and has self-locking properties.

[0029] The second pre-tightening component creates a pre-tightening force between the second rotating shaft and the fixed plate and rotating limit plate. This causes the second rotating shaft to drive the fixed plate and rotating limit plate to rotate. When the rotation of the display screen is obstructed, only the second worm gear drives the second rotating shaft to rotate, while the fixed plate and rotating limit plate do not rotate, stopping the display screen's rotation. This prevents damage to the second geared motor and avoids accidents to personnel. Alternatively, when the mounting plate is manually rotated, if the sum of the forces applied to the mounting plate exceeds the pre-tightening force (friction) between the fixed plate and the second rotating shaft, the second rotating shaft will not rotate, but the fixed plate will rotate. For example, when the mounting plate is manually pushed, if the force applied to the mounting plate does not exceed 50 kN, the fixed plate can overcome the static friction (rotational damping) between itself and the second rotating shaft. The second rotating shaft remains stationary, while the fixed plate rotates around the second rotating shaft, reducing the force required for manual rotation.

[0030] Since the fixed plate and the rotating shaft are not fixed, but rotated by clamping force, the mounting plate can also be manually driven to rotate 360°.

[0031] In this embodiment, the second pre-tightening assembly includes a third butterfly-shaped washer 241 sleeved on the second rotating shaft and located behind the second worm gear. A pre-tightening nut 242, which abuts against the rear side of the third butterfly-shaped washer, is externally threaded onto the rear part of the second rotating shaft. A third washer 245, located between the rotating limiting plate and the rotating seat, and a fourth butterfly-shaped washer 243, located in front of the fixed plate, are sleeved on the second rotating shaft. A limiting plate 244, which abuts against the front side of the fourth butterfly-shaped washer, is internally threaded onto the second rotating shaft. The third butterfly-shaped washer, the fourth butterfly-shaped washer, and the third washer and the second rotating shaft all have corresponding anti-rotation structures. Thus, the pre-tightening nut 542 pre-tightens the fixed plate and the rotating limiting plate, creating a pre-tightening force between the fixed plate, the rotating limiting plate, and the rotating seat, facilitating the rotation of the fixed plate and the rotating limiting plate by the second rotating shaft.

[0032] In this embodiment, the anti-rotation structure on the second pre-tightening assembly is as follows: an arc-shaped structure is cut off from the upper and lower parts of the front and rear of the second rotating shaft to form a waist-shaped cross-section, as shown in the second rotating shaft structure diagram; a section of the second rotating shaft has a circular cross-section; the third butterfly gasket, the fourth butterfly gasket, the second worm gear, and the third gasket each have a waist-shaped hole that mates with the first rotating shaft, thereby preventing rotation between the third butterfly gasket, the fourth butterfly gasket, the second worm gear, and the second rotating shaft.

[0033] In this embodiment, the third butterfly gasket, the fourth butterfly gasket, and the third gasket can be made of POM material to improve wear resistance.

[0034] In this embodiment, to achieve electric rotation limiting, the electric rotation limiting mechanism includes a radial protrusion 261 disposed on the rotation limiting plate, a longitudinal bending portion 262 disposed on the radial protrusion, and an arc-shaped groove 201 disposed on the front side of the rotating seat. The longitudinal bending portion extends into the arc-shaped groove and can move within the arc-shaped groove. A left-hand limit switch 202 and a right-hand limit switch 203 are correspondingly disposed on both sides of the arc-shaped groove for cooperating with the radial protrusion. The left-hand limit switch 202 and the right-hand limit switch 203 are electrically connected to the geared motor, so that the geared motor stops rotating after the radial protrusion touches the left-hand limit switch 102 or the right-hand limit switch 103.

[0035] In this embodiment, decorative shells are installed on the outer side of the rotating seat and the rear side of the mounting plate to improve the decorative effect and prevent dust from entering the rotating seat and affecting the operation of the electrical equipment; the mounting plate, rotating seat, and connecting seat are provided with a number of mounting holes so as to connect and install with corresponding components as needed.

[0036] The above description is only a preferred embodiment of the present invention. For those skilled in the art, designing different forms of electric rotating devices for display mounts based on the teachings of the present invention does not require creative labor. All equivalent changes, modifications, substitutions and variations made in accordance with the scope of the patent application of the present invention without departing from the principles and spirit of the present invention shall be covered by the present invention.
