[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] A television electric flip folding hanger, such as Figure 1 , Figure 3 As shown, it includes a base 1, a flip frame 2 with one end hinged to the base 1, and a TV mounting frame 3 installed on the flip frame 2. The base 1 is installed with a motor 4, the motor 4 is connected to a winding wheel 5, and the winding wheel 5 is provided with a steel cable 6. The winding end of the steel cable 6 is fixed to the winding wheel 5, and the unwinding end of the steel cable 6 is fixed to the movable end of the flip frame 2.

[0025] When this application is working normally, Figure 1 , Figure 2 , Figure 3 As shown, the motor 4 drives the winding wheel 5 to rotate. During the clockwise or counterclockwise rotation, the winding wheel 5 unwinds or reels the steel cable 6, so that the steel cable 6 applies force to the movable end of the flip frame 2, thereby forcing the flip frame 2 to flip, that is, controlling the angle change of the TV. Compared with the push rod structure in the prior art, the compactness of the structure is effectively improved, and the force point of the flip frame 2 is far away from the hinge point, with a larger lever arm, which effectively reduces the force requirement, and because the steel cable is flexible, the hidden danger of jamming is effectively eliminated.

[0026] To limit the turning angle of the turning frame 2, as Figure 1 , Figure 2 As shown, a limited rotation positioning rod 7 is arranged between the base 1 and the turning frame 2, one end of the limited rotation positioning rod 7 is rotatably connected to the turning frame 2, and the other end thereof is slidably and rotatably connected to the base 1; the base 1 is provided with a travel groove 8 for the top end of the limited rotation positioning rod 7 to slide and be rotatably connected; when the top end of the limited rotation positioning rod 7 is respectively at the two ends of the travel groove 8, the turning frame 2 is respectively in a closed state and a maximum expanded state; the limited rotation positioning rod 7 assists in positioning the turning angle of the turning frame 2, and while preventing the turning frame 2 from over-turning, effectively improves the angle accuracy of the turning frame 2 in the expanded state and the closed state.

[0027] The specific structure of the TV mounting bracket 3 is as follows: Figure 3 As shown, the TV mounting frame 3 includes an I-shaped main frame 9 fixed to the flip frame 2, and two fastening profiles 10 symmetrically slidably connected to the I-shaped main frame 9. The fastening profile 10 is provided with bolts to fasten with the I-shaped main frame 9, so that the relative distance between the two fastening profiles 10 is adjustable, thereby adapting to the installation requirements of televisions of various sizes and models; it should be noted that the fastening profile 10 is penetrated by a plurality of holes 11 for fixing with the TV bolts.

[0028] To improve the traction of the steel cable 6, Figure 3 As shown, a reduction ratio wheel set is provided between the output shaft of the motor 4 and the winding wheel 5, so that the torque output by the motor 4 drives the winding wheel 5 after being reduced in speed, thereby effectively improving the driving torque of the winding wheel 5, and further improving the traction force of the steel cable 6.

[0029] The specific structure of the reduction ratio wheel set is as follows: Figure 3 As shown, the reduction ratio gear set includes a worm 12, a worm wheel 13 meshing with the worm 12, an input gear 14 coaxially integrated with the worm wheel 13, and an output gear 15 coaxially integrated with the winding wheel 5, and the input gear 14 and the output gear 15 are meshed with each other; this allows the motor 4 to be installed in a manner where the central axis is parallel to the length center line of the base 1, further improving the structural compactness of the present application.

[0030] In order to improve the orderliness of the steel cable 6 being wound around the winding wheel 5, as Figure 3 , Figure 4 As shown, the circumferential surface of the winding wheel 5 is provided with a spiral guide groove 16 for the steel cable 6 to be wound in an orderly manner, thereby effectively preventing the steel cable 6 from becoming tangled and scattered.

[0031] In order to improve the force effect of the steel cable 6 on the turning frame 2, as Figure 3 , Figure 4 As shown, the base 1 is rotatably connected to a fixed pulley 17 away from the hinge end pin, and the steel cable 6 passes around the fixed pulley 17; thereby optimizing the traction angle of the steel cable 6 on the turning frame 2 and effectively improving the force effect.

[0032] The present application also includes an electric control system connected to the motor 4 by electrical signals, and the electric control system is used to control the start, stop and forward and reverse rotation of the motor 4.

[0033] To improve the safety of this application, Figure 4 , Figure 5 As shown, the base 1 is provided with an obstruction detection component; the obstruction detection includes a micro switch 18 connected to the electrical signal of the electric control system, and a trigger member 19 swingably connected to the base 1; the steel cable 6 has a trigger segment 20 between the winding wheel 5 and the fixed pulley 17, and the trigger segment 20 passes through the trigger member 19; when the trigger segment 20 is in a stretched state, the trigger member 19 is lifted; when the trigger segment 20 is in a relaxed state, the trigger member 19 hangs down and touches the micro switch 18.

[0034] When there is an obstruction within the unfolding and flipping activity trajectory of the TV, the TV rests against the obstruction. At this time, the motor 4 drives the winding wheel 5 to continuously release the steel cable 6. Under this working condition, since the free end of the steel cable 6 loses the reaction force from the flip frame 2, its trigger section 20 will gradually become loose, so that the trigger member 19 loses the lifting force, falls downward and triggers the micro switch 18. After the micro switch 18 is triggered, the electronic control system controls the motor 4 to stop output and rotate in the opposite direction until the micro switch 18 stops being triggered, that is, the trigger section 20 of the steel cable 6 returns to a straight state; in summary, the present application realizes the collision protection function by adding an obstacle detection component, thereby effectively reducing personal or property losses caused by accidents.

[0035] To ensure that the trigger 19 timely touches the micro switch 18, Figure 4 , Figure 5 As shown, the trigger member 19 is connected to a tension spring 21 , which provides elastic potential energy for the swinging tendency toward the micro switch 18 , thereby effectively improving the reliability and triggering sensitivity of the collision protection function.

However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
