Therefore, the supporting member 130 and the rotating member 110 can be stably supported, and the limiting effect is achieved, so that the stable rotation between the supporting member 130 and the rotating member 110 is ensured. It will be appreciated that the positioning collar 142 may also be provided on the rotary member 110 and the annular abutment 116 correspondingly provided on the support member 130 to achieve the desired rotational connection.

Referring to fig. 2, 3 and 4, the connecting assembly 140 further includes a retainer 144 and rolling members 146 uniformly distributed in the retainer 144, the annular stop 116 includes a connecting portion 1162 and an extending portion 1164 connected to each other, the positioning ring 142 includes an annular base 1422 and a limit stop 1424 disposed at one end of the annular base 1422, the limit stop 1424 abuts against the connecting portion 1162, the retainer 144 is disposed at an outer ring of the extending portion 1164, the annular base 1422 is disposed at an inner ring of the extending portion 1164, and the rolling members 146 respectively abut against the connecting portion 1162 and the supporting member 130.

Specifically, the cage 144 is circular, and is similar to the cage 144 of the rolling element 146 bearing, except that the cage 144 of the present application allows the rolling elements 146 to respectively leak out from both end surfaces of the cage 144 (see fig. 4). The rolling members 146 may be provided as balls, or the rolling members 146 may be provided in the form of a tapered cylinder or a circular cylinder according to the setting angle of the connecting portion 1162.

The limiting baffle 1424 is correspondingly provided with an annular protrusion, so that the limiting baffle 1424 abuts against the connecting portion 1162 through the annular protrusion, the axial movement of the rotating member 110 is avoided, and the rotating member 110 rotates more stably.

The driving assembly 150 and the arc transmission member 160 of the present application have the above two arrangements, and for convenience of description, the present application is described in a preferred embodiment, that is, the supporting member 130 is provided with the driving assembly 150 electrically connected to the controller, and the rotating member 110 is provided with the arc transmission member 160 drivingly connected to the driving assembly 150. Referring again to fig. 5, arc transmission member 160 includes an arc base 161 and gear teeth 162 disposed on an inner circumference of arc base 161, and driving assembly 150 is connected to arc transmission member 160 through gear teeth 162.

In this way, the display screen rotating mechanism 100 may be connected to a remote control or mobile terminal through a bluetooth module, such as a mobile phone, and may control the operation of the driving assembly 150 through the remote control or mobile terminal, so as to implement the switching of the horizontal screen or the vertical screen of the remote control display screen. The torque of the motor 152 is transmitted through the gear assembly 154, and the force transmission direction can be changed, which is beneficial to realize the rotation of the arc-shaped transmission member 160 at the required angle under the action of the motor 152.

Illustratively, the gear assembly 154 of the present application includes a guide transmission assembly 155, a first transmission gear 156, a second transmission gear 157, and a third transmission gear 158, and the output end of the motor 152 may be provided with a gear, and the rotation direction may be changed by the cooperation of the gear and the guide transmission assembly 155, so that the length extension direction of the motor 152 is parallel to the plate surface on which the supporting member 130 is located. Wherein, the gear set at the output end of the motor 152 may be a straight gear or a helical gear, and when the output end of the motor 152 adopts a helical gear, the guide transmission member may adopt a form of a transmission gear set on a worm, so that the torque transmitted to the worm is engaged with the first transmission gear 156 through the transmission gear of the guide transmission assembly 155; when the output of the motor 152 is a spur gear, the pilot transmission may be in the form of a face gear fixedly coupled to the transmission gear such that the torque transmitted to the face gear is engaged with the first transmission gear 156 through the transmission gear of the pilot transmission assembly 155. The first transmission gear 156 is meshed with the second transmission gear 157, the third transmission gear 158 is meshed with the second transmission gear 157, and the third transmission gear 158 is meshed with gear teeth 162 arranged on an arc-shaped base body 161 so as to realize required transmission connection. By adopting the parallel shaft transmission structure, the thickness of the display screen rotating mechanism 100 is reduced, the occupied space is reduced, and the user experience is further improved.

It should be noted that the gear assembly 154 is not limited in particular by the present embodiment, as long as the required transmission connection is satisfied. Illustratively, the number of intermeshing gears in the gear assembly 154 may be two, three, four, or the like.

As shown in fig. 6, the driving assembly 150 further includes a first housing 151 and a second housing 159 engaged with each other, and the motor 152 and the gear assembly 154 are located between the first housing 151 and the second housing 159. Thus, a cavity is formed between the first housing 151 and the second housing 159, so that the motor 152 and the gear assembly 154 are located in the cavity, which can play a role of dust prevention and avoid the influence of dusty environment on the stability of transmission.

As shown in fig. 5 and 6, a first blocking piece 164 and a second blocking piece 166 are respectively disposed at two ends of the arc-shaped base 161, and a first limiting assembly 136 and a second limiting assembly 138 are correspondingly disposed on the supporting member 130; the first limiting component 136 comprises a first limiting seat 1362 and a first limiting switch 1364 arranged on the first limiting seat 1362, and the second limiting component 138 comprises a second limiting seat and a second limiting switch arranged on the second limiting seat; the first catch 164 is adapted to cooperate with a first limit switch and the second catch 166 is adapted to cooperate with a second limit switch.

Specifically, the length of the arc-shaped base body 161 is greater than ninety radians, so that when the display screen is switched between the horizontal screen mode and the vertical screen mode, the gear teeth 162 on the arc-shaped base body 161 are not disengaged from the gear assembly 154 due to the too short length of the arc-shaped base body 161 in the meshing transmission process, so that the gear jamming is avoided, and the transmission stability is improved.

By respectively arranging the first blocking piece 164 and the second blocking piece 166 at two ends of the arc-shaped base body 161, and the first limit switch 1364 arranged on the first limit seat 1362 and the second limit switch arranged on the second limit seat, when the first blocking piece 164 corresponds to the first limit switch in position, the induction signal of the first limit switch 1364 changes, and the controller controls the motor 152 to stop operating according to the change of the induction signal. Similarly, when the second blocking piece 166 corresponds to the position of the second limit switch, the sensing signal of the second limit switch changes, and the controller controls the motor 152 to stop operating according to the change of the sensing signal. Thereby ensuring the accuracy of the rotational position of the rotary member 110.

In addition, the first limiting seat 1362 and the second limiting seat are respectively arranged on the circumference where the arc-shaped base body 161 rotates, the first limiting seat 1362 is arranged at the first limiting position where the arc-shaped base body 161 rotates, and the second limiting seat is arranged at the second limiting position where the arc-shaped base body 161 rotates. The first restraint socket 1362 may be used for mechanical restraint if the arcuate base 161 is at the first limit position and cannot be automatically stopped. Similarly, the second stop can be used for mechanical stopping if the arc-shaped base 161 is at the second stop position and cannot be stopped automatically. Therefore, the rotating position of the arc-shaped substrate 161 can be directly controlled by the controller, and can also be controlled by the first limit switch 1364 and the second limit switch in an auxiliary manner, and is limited by the first limit seat 1362 and the second limit seat, so as to improve the stability of rotation.

The working process of the display screen rotating mechanism 100 of the application is as follows:

in the normal use in-process, if the display screen is in horizontal screen state, when needs switch over to erecting the screen, the screen signal is erected in accessible cell-phone or remote controller input, and the controller passes through bluetooth module and receives erecting the screen signal, and then control motor 152 work. The motor 152 drives the gear assembly 154 to move, and the gear assembly 154 drives the arc-shaped transmission member 160 to start rotating through the gear teeth 162 on the inner ring of the arc-shaped base body 161, so as to drive the rotating member 110 and the display screen to rotate synchronously. Through the control program of the controller, when the display screen is rotated by 90 °, the controller will directly stop driving the motor 152 to stop the rotation of the motor 152. When the controller directly controls the display screen to have no response, the second stop piece 166 corresponds to the second limit switch, and a stop signal is fed back to the controller to stop driving, so that the display screen is ensured to rotate 90 degrees and just be in a vertical screen state.

When the horizontal screen state needs to be switched back, a horizontal screen signal can be input through the mobile phone or the remote controller, the controller receives the horizontal screen signal through the Bluetooth module, and then the motor 152 is controlled to work (the rotating direction is opposite to the rotating direction of the received vertical screen signal). The motor 152 drives the gear assembly 154 to move, and the gear assembly 154 drives the arc-shaped transmission member 160 to rotate back through the gear teeth 162 on the inner ring of the arc-shaped base body 161, so as to drive the rotating member 110 and the display screen to rotate synchronously. Through the control program of the controller, when the display screen is rotated by 90 °, the controller will directly stop driving the motor 152 to stop the rotation of the motor 152. When the controller directly controls the display screen to have no response, the first blocking piece 164 corresponds to the first limit switch 1364, and a stop signal is fed back to the controller to stop driving, so that the display screen is ensured to rotate for 90 degrees and just be in a transverse screen state.

As shown in fig. 5, a plurality of damping members 139 are disposed between the support member 130 and the rotary member 110, and the damping members 139 are disposed on the support member 130 or the rotary member 110.

Specifically, the damping member 139 may be made of a flexible material having elasticity, such as rubber or resin, so as to prevent the supporting member 130 and the rotating member 110 from shaking during relative rotation, thereby making the rotation more stable. The present application does not specifically limit the arrangement form and number of the damping members 139, as long as the stable rotation between the supporting member 130 and the rotating member 110 can be ensured. For example, when the damping member 139 is disposed on the supporting member 130, a protrusion may be disposed at a supporting position of the damping member 139 and the rotating member 110, and the protrusion abuts against the rotating member 110. Similarly, when the damping member 139 is disposed on the rotating member 110, a protrusion may be disposed at a supporting position of the damping member 139 and the supporting member 130, and the protrusion abuts against the supporting member 130. In addition, the number of the damping members 139 may be three or four, and a plurality of the damping members 139 may be uniformly distributed to ensure the stability of the abutting.

As shown in fig. 2, the supporting member 130 and the rotating member 110 are circular, the supporting member 130 includes a second base plate 132, the first folding edge 114 is disposed on the outer ring of the first base plate 112, the second folding edge 134 is disposed on the outer ring of the second base plate 132, and the first folding edge 114 and the second folding edge 134 are disposed opposite to each other.

Specifically, the circular shapes of the supporting member 130 and the rotating member 110 are the same, and when the supporting member 130 and the rotating member 110 rotate relatively, the first folding edge 114 of the outer ring of the first base plate 112 and the second folding edge 134 of the outer ring of the second base plate 132 are disposed relatively, so that the supporting member 130 and the rotating member 110 have better sealing performance, which is beneficial to protecting the parts such as the driving assembly 150, the arc-shaped transmission member 160, the first limiting assembly 136 and the second limiting assembly 138 disposed between the supporting member 130 and the rotating member 110, and also makes the space between the supporting member 130 and the rotating member 110 more compact. In addition, the fixing base 120 may also be set to be circular, so that the whole display screen rotating mechanism 100 is smaller and more compact, and the probability of collision is also smaller due to the increase of edges and corners.

The embodiment of the utility model provides a still disclose a display screen, including the display screen body to and display screen rotary mechanism 100 in the aforementioned embodiment, display screen rotary mechanism 100's rotating member 110 and display screen body fixed connection.
