Detailed Description
The utility model will be further described with reference to the accompanying drawings and detailed description below:
the following is presented in connection with fig. 1-5: the folding screen 1 is rotatably arranged on the top of the lifting frame 2, and the lifting frame 2 is vertically and slidably arranged in the case 6. The lifting motor 5 is fixed at the bottom of the case 6, and the lifting motor 5 is used for driving the lifting frame 2 to slide up and down. The lifting frame 2 is lifted to the highest position in the case 6, the folding screen 1 is completely exposed out of the case 6, and an opening is formed in the top of the case 6 for the folding screen 1 to come in and go out from. The folding screen 1 is rectangular, and only the front of the folding screen 1 can be used for displaying information, and the upper half part and the lower half part of the folding screen 1 can be fully folded in half. The folding angle of the folding screen 1 after being fully folded in half is recorded as zero degree, and the folding angle of the folding screen 1 after being fully unfolded is recorded as 180 degree. In the case where the folding screen 1 is fully unfolded, i.e., the folding angle of the folding screen 1 is 180 degrees, the upper half and the lower half of the folding screen 1 are in the same plane. The display screen 8 is fixedly arranged on the upper half part of the back surface of the folding screen 1. In the case of a completely folded-in-half folding screen 1, i.e. the folding angle of the folding screen 1 is zero degrees. The folding range of the folding screen 1 is zero degrees to 180 degrees, and the folding of the folding screen 1 is achieved manually. The folding screen 1 can maintain its physical form after the user performs a folding operation. The display screen 8 is used for displaying the information of names, functions and the like of the participants, and the folding screen 1 is used for displaying conference contents.
The overturning motor 4 is arranged on the lifting frame 2, and the overturning motor 4 is used for driving the bottom of the folding screen 1 to overturn around the joint of the folding screen 1 and the lifting frame 2. And the controller 3 is fixedly arranged on the lifting frame 2, the key 10 is arranged at the top end of the chassis 6, the controller 3 is electrically connected with the key 10, and the controller 3 is electrically connected with the lifting motor 5 and the overturning motor 4 respectively. The keys 10 are divided into an up key and a down key, the up key having three gear positions.
The inner wall of the case 6 is provided with two optocoupler limit switches 7, and the two optocoupler limit switches 7 are respectively an upper limit switch and a lower limit switch. The two optocoupler limit switches 7 are fixedly arranged on the inner wall of the case 6. And the two optocoupler limit switches 7 are positioned on the same vertical line, and the distance between the two optocoupler limit switches 7 is the range of the lifting frame 2 sliding up and down. When the lifting frame 2 is lifted to the position for triggering the upper limit switch, the folding screen 1 is just completely exposed out of the case 6. The two optocoupler limit switches 7 are electrically connected with the controller 3, and the controller 3 is electrically connected with the lifting motor 5.
The side edge of the lower half part of the front surface of the folding screen 1 is provided with an inductor 9, and the inductor 9 is electrically connected with the controller 3. When the upper half part and the lower half part of the folding screen 1 are fully folded in half, namely the folding angle of the folding screen 1 is zero, the inductor 9 arranged on the lower half part of the folding screen 1 is fully shielded by the upper half part of the folding screen 1, the controller 3 receives a signal sent by the inductor 9, and then the controller 3 drives the lifting motor 5 to drive the lifting frame 2 to descend. The inductor 9 is used for guaranteeing that when the folding screen 1 is fully folded in half, the folding screen 1 can be lowered, and the folding screen 1 is prevented from being lowered under the condition that the folding screen 1 is not fully folded in half, so that the folding screen 1 collides with an opening of the case 6.
Wherein, the folding screen 1 is internally provided with a damping hinge structure which is used for supporting the folding screen 1 to fold and position.
Working principle: in the initial state, the folding screen 1 is in the cabinet 6, and the folding screen 1 is in a fully folded-in-half state. After the rising key is pressed for the first time, namely the first gear of the rising key is selected, the folding screen 1 is vertically lifted to the highest position, and the folding screen 1 is always in a completely folded state in the process. It should be noted that, the up-down movement range of the lifting frame 2 is always limited between the two optocoupler limit switches 7. After the rising key is pressed for the second time, namely the second gear of the rising key is selected, the lower half part of the folding screen 1 is turned backwards by about 10 degrees around the joint of the folding screen 1 and the lifting frame 2. After the rising key is pressed for the third time, namely the third gear of the rising key is selected, the lower half part of the folding screen 1 turns backwards around the joint of the folding screen 1 and the lifting frame 2, and the turning angle is 29 degrees relative to the vertical direction. After the rising key is pressed for the first time, the rising key can be pressed for the second time at any time, and after the rising key is pressed for the second time, the rising key can be pressed for the third time at any time. The maximum turning angle of the folding screen 1 relative to the vertical direction is set to 29 degrees, namely, after the rising key is pressed for the third time, the rising key is pressed continuously, and the physical state of the folding screen 1 is kept unchanged.
The user presses the descending button to send a signal to the controller 3, so that the controller 3 sequentially drives the overturning motor 4 and the lifting motor 5 to work, the overturning motor 4 drives the folding screen 1 to overturn to the vertical direction, and then the lifting motor 5 drives the lifting frame 2 and the folding screen 1 to descend. In order to prevent the folding screen 1 which is not completely closed from being scratched with the top opening of the case 6 when the folding screen 1 which is not completely closed is lowered, a sensor 9 is arranged at the side edge of the lower half part of the front surface of the folding screen 1. Under the condition that the folding screen 1 is unfolded, the sensor 9 senses light, so that the controller 3 is electrically disconnected with the lifting motor 5, and the lifting motor 5 cannot work. When the folding screen 1 is fully folded in half, the inductor 9 cannot sense light, and then the inductor 9 is electrically connected with the controller 3, the inductor 9 sends a signal to the controller 3, namely the controller 3 releases the limitation of the descending of the lifting motor 5. The user presses the down button, so that the controller 3 drives the lifting motor 5 to drive the folding screen 1 to descend. Namely, when the folding screen 1 is completely exposed out of the case 6, the folding screen 1 is completely folded and the lower half of the folding screen 1 is reset to the vertical state to descend, and the folding screen 1 is completely folded and the lower half of the folding screen 1 is reset to the vertical state. That is, when it is necessary to store the folding screen 1 completely exposed outside the cabinet 6 in the cabinet 6, the folding screen 1 must be in a completely folded state.
The folding screen 1 is turned over and the folding screen 1 is folded, and the two actions are independent and do not interfere with each other. The turning of the folding screen 1 is controlled by a turning motor 4, and the folding of the folding screen 1 is manually finished by a user.
Various other corresponding changes and modifications will occur to those skilled in the art from the foregoing description and the accompanying drawings, and all such changes and modifications are intended to be included within the scope of the present utility model as defined in the appended claims.
