Fig. 3 is a schematic structural view of the rotary hanger 2 of fig. 1. Fig. 4 is an exploded view of fig. 3. Fig. 5 is a sectional view of fig. 3. Fig. 6 is a schematic structural view of the rotary hanger 2 of fig. 3 with the rotary plate 23 removed. Fig. 7 is a schematic structural view of the fixing plate 21 in fig. 4. Fig. 8 is a side view of fig. 7.

Referring to fig. 2 to 8, the rotating rack 2 is disposed at the back side of the display main body 1. The rotary hanger 2 comprises a fixed plate 21, a hanging disc 22, a rotating plate 23, a bearing 24, a rotating mechanism and a driving mechanism.

Referring to fig. 7 and 8, the fixing plate 21 can be used as a preset support for fixing on a wall or an installation platform in advance. In some embodiments, the fixing plate 21 is provided with a plurality of fixing holes 211 arranged at intervals in the circumferential direction. The fixing hole 211 can be used to fix the fixing plate 21 to a wall or a mounting platform. It will be appreciated that the number of fixation holes 211 may be increased or decreased accordingly as desired. The fixing hole 211 may be a long hole or a kidney-shaped hole to facilitate fine adjustment of the position of the fixing plate 21 on the wall.

Referring to fig. 8 in conjunction with fig. 4, a boss 212 is protruded from the front side of the fixing plate 21. The projection 212 is formed in an arc shape, and a plurality of projections 212 may be provided to form a certain interval space at the front side of the fixing plate 21.

The boss 212 is provided with a hook 213 protruding forward, and the hook 213 may be a mushroom-like rivet. The hook 213 may be provided in plurality, and the plurality of hooks 213 are arranged at intervals for stably hooking the hanging tray 22. In some embodiments, a receiving groove 214 corresponding to the boss 212 is recessed at the back side of the fixing plate 21, so that the hook 213 can be detachably fixed at the front side of the boss 212 by a nut or the like, and the nut can be just received in the receiving groove 214 to prevent the fixing plate 21 from being mounted on the wall.

Referring to fig. 2 to 6, the hanging plate 22 is detachably disposed at the front side of the fixing plate 21. The hanging tray 22 is mainly used to hang and support other components, and the hanging tray 22 is hung on the fixing plate 21 and serves as a main support of the display main body 1.

Hanging tray 22 may take a circular configuration. An accommodating cavity is concavely formed at the front side of the hanging disc 22 for accommodating the rotating mechanism.

The hanging plate 22 is provided with a plurality of hanging holes 221 which are arranged at intervals. The hanging hole 221 is used to cooperate with the hook 213 of the fixing plate 21, so that the hanging plate 22 can be detachably hung on the fixing plate 21.

In some embodiments, the hanging aperture 221 includes a first circular aperture 2211 and a second circular aperture 2212 that communicate with each other. Second circular hole 2212 is located below first circular hole 2211, and the aperture of second circular hole 2212 is greater than the aperture of first circular hole 2211. The outer diameter of the front end portion of the hook 213 is larger than the aperture of the first circular hole 2211 and smaller than the aperture of the second circular hole 2212. When the hanging disc 22 needs to be hung on the fixing plate 21, the second circular hole 2212 can be opposite to the hook 213, so that the front end of the hook 213 passes through the second circular hole 2212, then the hanging disc 22 is hung downwards, the hook 213 enters the first circular hole 2211, the front end of the hook 213 is clamped and locked at the first circular hole 2211, and therefore the hanging disc 22 is stably hung on the fixing plate 21.

In some embodiments, the hanging plate 22 defines a first wire passing hole 222 axially passing through the hanging plate 22. The first wire passing hole 222 is mainly used for passing a wire. It is understood that the first wire passing hole 222 may be formed at the axial center of the hanging plate 22, or at other positions as required. The external connection wire of the display device can reasonably pass through the first wire through hole 222 and extend out of the rotary hanger 2 from the space between the hanging disc 22 and the fixing plate 21 for external connection.

Referring to fig. 2, 4 and 6, in some embodiments, the rear side of the hanging plate 22 is recessed with a radially extending wire groove 223. The wire guide groove 223 is communicated with the first wire guide hole 222, so that an external wire of the display device can be reasonably accommodated in the wire guide groove 223 and extends out of the rotary hanger 2 through the wire guide groove 223 to be externally connected.

Still referring to fig. 2 to 6, the rotating plate 23 is rotatably connected to the front side of the hanging plate 22 around a shaft, and the shaft axis of the rotating plate 23 may be the central axis of the rotating plate 23. An interval is arranged between the rotating plate 23 and the hanging disc 22, and the accommodating cavity at the front side of the hanging disc 22 is clamped between the hanging disc 22 and the rotating plate 23. The rotating plate 23 is connected to the back side of the display main body 1, so that the rotating plate 23 can drive the display main body 1 to rotate together in the plane of the display main body 1 relative to the hanging tray 22. The rotation plate 23 may be fixed to the back side of the display main body 1 by a plurality of screws to improve stability of connection between the rotation plate 23 and the display main body 1.

In some embodiments, bearing 24 is disposed between rotating plate 23 and hanging tray 22 to enable relative rotation between rotating plate 23 and hanging tray 22. The bearing 24 includes an inner ring 241 and an outer ring 242 coaxially sleeved. Outer ring 242 is fixed to the front side of hanger plate 22, and the housing cavity of hanger plate 22 is located within the contour of outer ring 242. The inner ring 241 is positioned inside the outer ring 242 and can rotate relative to the outer ring 242, and the inner ring 241 is fixed on the back side of the rotating plate 23, so that when the inner ring 241 rotates relative to the outer ring 242, the inner ring 241 can drive the rotating plate 23 to rotate relative to the hanging disc 22.

After the hanging disc 22 and the rotating plate 23 are connected through the inner ring 241 and the outer ring 242 which are coaxially sleeved, the hanging disc 22 and the rotating plate 23 can form a coaxial connection structure.

It is understood that the inner ring 241 can also be connected to the hanging disc 22, and the outer ring 242 can be connected to the rotating plate 23, and the relative rotation between the rotating plate 23 and the hanging disc 22 can also be driven by the relative rotation between the inner ring 241 and the outer ring 242.

Referring to fig. 5, the inner ring 241 and the outer ring 242 are disposed in a staggered and overlapping manner in the front-rear direction. That is, the front end surface of the inner ring 241 protrudes forward beyond the front end surface of the outer ring 242, so that the rotating plate 23 and the outer ring 242 have a certain space therebetween, thereby preventing the rotating plate 23 and the outer ring 242 from contacting each other and hindering the relative rotation during the relative rotation. Similarly, the rear end surface of the outer ring 242 protrudes rearward beyond the rear end surface of the outer ring 242, so that a certain space is provided between the hanging disc 22 and the inner ring 241, and the phenomenon that the hanging disc 22 and the inner ring 241 contact with each other to hinder the relative rotation is avoided during the relative rotation process.

The rotating plate 23 may have a circular structure and may rotate about its center with respect to the hanging plate 22. The diameter of the rotating plate 23 may be the same as the outer diameter of the inner ring 241, so as to facilitate the alignment connection between the inner ring 241 and the rotating plate 23. It is understood that the hanging plate 22 may have the same diameter as the outer diameter of the outer ring 242 to facilitate the alignment connection between the outer ring 242 and the hanging plate 22.

Referring to fig. 2 to 4, in some embodiments, a second wire passing hole 231 is formed at the center of the rotating plate 23, and the second wire passing hole 231 may be opposite to the first wire passing hole 222 on the hanging tray 22. The external signal line of the display main body 1 can extend out through the back plate 12 at the back, sequentially pass through the second wire passing hole 231 on the rotating plate 23 and the first wire passing hole 222 on the hanging disc 22, and then be led out from the rotary hanging frame 2 through the wire groove 223, so that the external signal line can be managed and externally connected. Meanwhile, when the display main body 1 and the rotating plate 23 rotate relative to the hanging disc 22, the external signal wire can be reasonably and reliably connected to the outside without winding.

Referring to fig. 3 to 6, the rotating mechanism is used for driving and controlling the rotating plate 23 to rotate relative to the hanging plate 22. The rotating mechanism is arranged on the hanging disc 22 and can be arranged in the accommodating cavity of the hanging disc 22. The drive mechanism includes a drive motor 25, a gear box 26, a circuit board 29, a first position sensor 201, and a second position sensor 202. The swivel mechanism comprises a knob 27 and a slider 28.

The driving motor 25 is installed in the receiving cavity of the hanging tray 22 as a power source for providing a driving force for rotation. The drive motor 25 may be a general motor, a stepping motor, or a servo motor.

Gearbox 26 is mounted to spider 22. And the input end of the gearbox 26 is connected with the output end of the driving motor 25, so as to reduce the speed of the power output by the driving motor 25 and improve the torque.

The rotary handle 27 is arranged between the hanging disc 22 and the rotating plate 23. One end of the rotary handle 27 is connected with the output end of the gearbox 26, so that the rotary handle 27 can rotate and rotate at a constant speed under the driving of the driving motor 25 and the gearbox 26.

The slider 28 is provided at the other end of the handle 27. With the uniform rotation of the rotary handle 27, the sliding block 28 can perform uniform circumferential rotation motion. The rotating plate 23 is provided with a sliding groove 232 extending along the radial direction thereof, and the sliding block 28 is extended and limited in the sliding groove 232 and can slide along the sliding groove 232. In the process that the sliding block 28 rotates along with the rotating handle 27, the sliding block 28 can push the rotating plate 23 to rotate through the side wall of the sliding groove 232, and then the rotating plate 23 drives the display main body 1 to rotate relative to the hanging disc 22 in the plane where the display main body is located.

It is understood that the sliding block 28 may also be disposed in the middle of the rotary handle 27, and can also rotate circumferentially along with the rotation of the rotary handle 27, so as to drive the rotary plate 23 to rotate. The slider 28 may be disposed at other portions of the handle 27, and only a space is required from the rotational axis of the handle 27, so that the slider 28 can perform a circumferential rotational movement around the rotational axis of the handle 27.

It should be noted that the rotation axes of the slider 28 and the knob 27 are not aligned with the rotation axis of the rotating plate 23, and they are parallel to the compartments. Therefore, the rotation locus of the slider 28 is different from the rotation locus of the slide groove 232, and the slider 28 can slide in the slide groove 232 relative to the slide groove 232 during the rotation process.

The circuit board 29 is arranged in the accommodating cavity of the hanging disc 22, and the driving motor 25 is electrically connected with the circuit board 29. The circuit board 29 is used for supplying power to the driving motor 25 and controlling the driving motor 25 to be turned on or off. An inductor 291, such as a hall inductor 291, is integrated on the circuit board 29.

The first position sensor 201 and the second position sensor 202 are disposed on the rotating plate 23 at intervals in the circumferential direction, and may respectively face the sensor 291 integrated on the circuit board 29, and generate sensing signals to control the start and stop of the driving motor 25 and the stop position of the rotating plate 23. Wherein the first position sensor 201 and the second position sensor 202 may employ magnets for cooperating with the inductor 291 device integrated on the circuit board 29.

The states and operation principles of the lever 27, the slider 28, and the slide groove 232 in different rotation states of the display main body 1 will be described in detail below.

Fig. 9 is a schematic structural diagram showing the main body 1, the rotating handle 27, the rotating plate 23 and the sliding groove 232 when the main body 1 rotates 0 °, which shows the first state of the main body 1, in which the rotating handle 27 is perpendicular to the sliding groove 232. Fig. 10 is a schematic structural view of the rotary handle 27, the rotary plate 23 and the sliding groove 232 in fig. 9.

Referring to fig. 9 and 10 in conjunction with fig. 3, the display main body 1 and the rotation plate 23 in this state are rotated by 0 ° to be in a first state of being horizontally displayed, i.e., a landscape state. The display main body 1 in the landscape state can be normally used.

The rotary handle 27 is rotated at a constant speed by the driving motor 25, so that the slider 28 has constant linear and angular velocities.

In this state, the rotary handle 27 is just perpendicular to the sliding groove 232, and the slide block 28 is located at the inner end of the sliding groove 232, i.e., the end of the sliding groove 232 close to the rotation axis of the rotating plate 23. At this time, the linear velocity of the slider 28 is parallel to the chute 232, the slider 28 generates no pressing force on the chute side wall of the chute 232, the rotating plate 23 does not rotate, and the angular velocity of the rotating plate 23 is the minimum.

In the first state, the first position sensor 201 is just opposite to the sensor 291 integrated on the circuit board 29, and the circuit board 29 can receive a position signal from the first position sensor 201 sensed by the sensor 291, i.e. a position signal indicating that the main body 1 is in the first state, and control the motor to start or stop.

Fig. 11 is a schematic structural view showing the main body 1, the rotary handle 27, the rotary plate 23 and the sliding groove 232 when the main body 1 rotates 10 °. Fig. 12 is a schematic structural view of the knob 27, the rotating plate 23 and the sliding groove 232 in fig. 11.

Referring to fig. 11 and 12 in conjunction with fig. 3, the display main body 1 and the rotation plate 23 in this state are rotated by 10 °.

In this state, when the slider 28 rotates with the rotary handle 27, the angle of the linear velocity sliding groove 232 of the slider 28 is larger than 0 ° and smaller than 90 °, the linear velocity of the slider 28 can be transmitted to the rotating plate 23 through the groove side wall of the sliding groove 232, so that the rotating plate 23 rotates at a gradually increased speed, and the angular velocity of the rotating plate 23 gradually increases.

Fig. 13 is a schematic structural view showing the main body 1, the rotary handle 27, the rotary plate 23 and the sliding groove 232 when the main body 1 rotates 45 °. Fig. 14 is a schematic structural view of the knob 27, the rotating plate 23 and the sliding groove 232 in fig. 13.

Referring to fig. 13 and 14 in conjunction with fig. 3, the display main body 1 and the rotation plate 23 in this state are rotated at an angle of 45 °.

In this state, the rotary handle 27 is just parallel to the slide groove 232, and the slide block 28 is located at the outer end of the slide groove 232, i.e., the end of the slide groove 232 away from the rotation axis of the rotating plate 23.

In this state, when the slider 28 rotates with the rotary handle 27, the linear velocity of the slider 28 is at an angle of 90 ° to the linear velocity of the slider 28, and the linear velocity of the slider 28 can be maximally transmitted to the rotating plate 23 through the side wall of the slot 232, so that the angular velocity of the rotating plate 23 is maximized.

Fig. 15 is a schematic structural view showing the main body 1, the rotating handle 27, the rotating plate 23 and the sliding groove 232 when the main body 1 is rotated by 90 °, which shows a second state of the main body 1 in which the rotating handle 27 is perpendicular to the sliding groove 232. Fig. 16 is a schematic structural view of the knob 27, the rotating plate 23 and the sliding groove 232 in fig. 15.

Referring to fig. 15 and 16 in conjunction with fig. 3, the display main body 1 and the rotation plate 23 in this state are rotated by 90 ° to be in a second state of vertical display, i.e., a vertical screen state. The display main body 1 in the vertical screen state can be suitable for being intelligently interconnected with electronic products such as mobile phones and the like, and the vertical screen playing effect is met.

In this state, the rotary handle 27 is just perpendicular to the sliding groove 232, and the sliding block 28 is located at the inner end of the sliding groove 232, i.e., the end of the sliding groove 232 close to the rotation axis of the rotating plate 23. At this time, the linear velocity of the slider 28 is parallel to the slide groove 232, the slider 28 does not generate a pressing force on the groove side wall of the slide groove 232, and the angular velocity of the rotating plate 23 is minimized again.

In the second state, the second position sensor 202 is just opposite to the sensor 291 integrated on the circuit board 29, and the circuit board 29 can receive a position signal from the second position sensor 202 sensed by the sensor 291, i.e. a position signal indicating that the main body 1 is in the second state, so as to control the motor to start or stop.

It will be appreciated that the first position sensor 201 and the second position sensor 202 are mounted on the rotating plate 23 at 90 ° circumferential intervals. And the extension directions of the sliding grooves 232 on the rotating plate 23 are perpendicular to each other in the first state and the second state of the rotating plate 23.

Referring to fig. 9 to 16, in the process that the display main body 1 rotates from the first state to the second state, the driving motor 25 and the rotating handle 27 always rotate at a constant speed, but the rotation angular velocities of the display main body 1 and the rotating plate 23 gradually change from minimum to maximum, then gradually change from maximum to minimum, and reach maximum when rotating by 45 °, so as to realize the automatic speed regulation function of the rotation speed of the display main body 1, and the velocities of the initial state and the final state are both minimum, so that the display main body 1 is rotated and stopped, which is beneficial for the whole display device to overcome the large rotation inertia during rotation, and can effectively avoid the damage of the transmission part and further the failure of the whole rotating system caused by the sudden start of the sudden display main body 1.

Referring to fig. 9 to 14, in the process of rotating the display main body 1 and the rotating plate 23 from 0 ° to 45 °, the rotating speed of the display main body 1 and the rotating plate 23 increases, and the sliding block 28 gradually moves away from the center of the rotating plate 23.

Referring to fig. 13 to 16, in the process that the display main body 1 and the rotating plate 23 rotate from 45 ° to 90 °, the rotation speed of the display main body 1 and the rotating plate 23 decreases, and the sliding block 28 gradually approaches the center of the rotating plate 23.

In the course of the display main body 1 rotating from the first state to the second state, the rotation speed curve of the display main body 1 and the rotation plate 23 is a sine curve, the speed is slowly increased from 0, reaches the maximum at 45 °, and is slowly decreased to 0. The slide block 28 gradually moves away from the center of the rotating plate 23 and gradually approaches the center of the rotating plate 23.

Based on the technical scheme, the embodiment of the invention at least has the following advantages and positive effects:

in the display device of the embodiment of the invention, the display main body 1 is driven to rotate by the rotating hanging frame 2. Wherein, the rotation that utilizes swing handle 27 drives the slider 28 rotatory, and then drives through the cooperation of slider 28 and spout 232 and change board 23 and rotate, finally drives through changeing board 23 and shows that main part 1 is rotatory in its plane relative hanging dish 22, realizes showing that the screen of main part 1 is rotatory, satisfies the user demand that the play was switched to horizontal vertical screen of user.

Meanwhile, the sensor 291 on the circuit board 29 is used to cooperate with the first position sensor 201 and the second position sensor 202 to detect the rotation position of the display main body 1, so that the first position sensor 201 and the second position sensor 202 respectively correspond to the states of the display main body 1 rotating by 0 ° and 90 °, thereby ensuring that the display main body 1 can be accurately stopped at a desired position.
