The first embodiment is as follows: as shown in fig. 1 to 6, an electric ground curtain comprises a curtain 1, supporting legs 2, an upper shell 3, a lower shell 4, a scroll 5, a bracket 6 and a power supply 7, wherein the lower end of the curtain 1 is connected to the scroll 5, the upper shell 3 is positioned at the upper end of the curtain 1, the lower shell 4 is positioned at the lower end of the curtain 1, the supporting legs 2 are positioned at the lower end of the lower shell 4, the power supply 7 and the scroll 5 are both positioned in the lower shell 4, a tubular motor 8 is transversely arranged in the lower shell 4, and the tubular motor 8 is connected with the power supply 7; the scroll 5 is tubular and is arranged outside the tubular motor 8; the two brackets 6 are arranged between the upper shell 3 and the lower shell 4 in a telescopic manner, the lower end of each bracket 6 is fixedly connected with the lower shell 4, the lower end of each bracket 6 is fixedly connected with the upper shell 3, and the two brackets 6 are arranged symmetrically left and right; the support 6 comprises a short arm 601 connected with the upper shell 3 and a long arm 602 connected with the lower shell 4, the lower end of the short arm 601 is rotatably connected with the upper end of the long arm 602, an included angle is formed between the short arm 601 and the long arm 602, and a spring 603 connecting the short arm 601 and the long arm is arranged at the included angle. The tubular motor 8 is positioned at one end inside the lower shell 4, the other end inside the lower shell 4 is provided with a tail plug wheel 9, and the tail plug wheel 9 and the tubular motor 8 are both provided with a clamping groove 901; the scroll 5 is recessed into a mounting groove 501 along the direction of the rotation axis, and the clamping grooves 901 are clamped on the outer wall of the mounting groove 501; the inslot of mounting groove 501 is provided with the first mounting bar 10 of detachable, and the lower extreme of curtain 1 is fixed on first mounting bar 10. A detachable second mounting strip 14 is arranged in the upper shell 3, and the upper end of the curtain 1 is fixed on the second mounting strip 14. The upper end cover 11 is arranged at each end of the upper shell 3, the lower end cover 12 is arranged at each end of the lower shell 4, and the socket 13 and the control switch 18 which are electrically connected with the power supply 7 are arranged on the lower end cover 12.

The principle is as follows: first, the power supply 7 can be charged by connecting to the outlet 13; when the curtain needs to be opened, the tubular motor 8 is controlled to rotate through the control switch 18, the tubular motor 8 drives the scroll 5 to rotate to start releasing the curtain 1, and under the action of the spring 603, the bracket 6 drives the upper shell 3 and the curtain 1 to move upwards and unfold until a required state is reached; when the curtain needs to be pulled in a closed manner, the tubular motor 8 is controlled to rotate reversely through the control switch 18, the tubular motor 8 drives the scroll 5 to rotate reversely to start to roll up the curtain 1 until the upper shell 3 and the lower shell 4 are closed, the curtain 1 and the internal structure of the shell are dustproof, sun-proof and waterproof due to the design of the shell, and the service life is prolonged.

When the floor screen needs to be used outdoors, the screen 1 can be made of a black gold screen 1 or a black grid screen 1, the light resistance is strong, and the picture contrast is high.

Wherein, spool 5, first mounting bar 10, second mounting bar 14, go up casing 3, lower casing 4, upper end cover 11 and lower end cover 12 all can adopt aluminium system product, and the processing of being convenient for can also alleviate whole weight, and cost is energy-conserving.

The long arm 602 of the support 6 and the surface of the lower shell 4 which is contacted with each other can be provided with a plurality of foot pads which can be made of rubber materials, and the floor-pulling curtain has a buffering effect when being closed, thereby ensuring the stable structure and reducing abnormal sound.

Example two: as shown in fig. 5, the spring 603 is a nitrogen spring, the body of the nitrogen spring 603 is connected to the long arm 602, and the nitrogen spring 603 is connected to the short arm 601 through a piston rod. The nitrogen spring 603 is stable in structure, good in performance and durable, abnormal sound caused by expansion with heat and contraction with cold of a common spring is avoided, silent opening and closing are achieved, texture is good, and the using effect of a consumer is good.

Example three: when the ground curtain is in a closed state, the included angle between the nitrogen spring 603 and the horizontal plane is more than 5 degrees. In order to ensure that the ground pulling curtain can be automatically opened, the component force of the two springs in the vertical direction is greater than the gravity of the upper part supported by the springs when the ground pulling curtain is opened, so that the nitrogen spring needs to have an inclination angle when the ground pulling curtain is in a closed state, the angle is designed according to practical application, and the angle designed in the embodiment is 5.2 degrees.

Example four: as shown in fig. 5, a row of adjusting holes 604 are disposed on both the short arm 601 and the long arm 602, and both ends of the spring 603 are detachably disposed in the adjusting holes 604 through pins. The included angle between the short arm 601 and the long arm 602 can be adjusted according to the actual application, and the unfolding height of the curtain 1 can be adjusted, so that the curtain is suitable for more occasions.

Example five: as shown in fig. 1, both sides of the curtain 1 are provided with a plurality of uniformly distributed threading holes 101, and a stay wire is arranged between the first mounting bar 10 and the second mounting bar 14 and penetrates through the threading holes 101. The design of acting as go-between can prevent the turn-up, and the steel wire line of parcel nylon layer can be adopted to act as go-between, guarantees that the line body is difficult for splitting, also is difficult for cutting the operator, and is safe firm again.

Example six: as shown in fig. 3 and 4, the upper casing 3 and the lower casing 4 are both provided with a silencing strip 15, and the silencing strip 15 is located at the closed position of the upper casing 3 and the lower casing 4 when the floor screen is in the closed state. The design of the silencing strip 15 can prevent the upper shell 3 and the lower shell 4 from directly contacting to generate noise, realize silencing opening and closing, and has good texture and good use effect for consumers; the silencing strip 15 can also prevent dust or water vapor and the like from entering the shell, and the service life of the equipment is prolonged.

Example seven: as shown in fig. 3, a power amplifier circuit board 16 and a lamp strip 17 connected with the power supply 7 are arranged in the lower shell 4, a loudspeaker, a time temperature module and a bluetooth power amplifier module are arranged in the upper shell 3, and the loudspeaker, the time temperature module and the bluetooth power amplifier module are all connected with the power amplifier circuit board in a bluetooth mode. The lamp strip 17 can play a role in prompting when the curtain 1 rises or falls, and can prevent collision and accidental injury. From the broadcast that can be used to sound of taking the speaker, need not to be equipped with audio equipment again, time temperature module can be used to show room temperature and time, the operation of being convenient for, and the practicality is strong.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
