[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-11 The present invention provides a technical solution: an interactive electric slide rail screen, comprising a wall 1 and an interactive screen 2, the interactive screen 2 is slidably mounted on the wall 1, a cleaning device is provided on the left side of the wall 1, the cleaning device comprises a sliding mechanism 3, a telescopic mechanism 4 and a wiping mechanism 5, the wiping mechanism 5 is fixedly mounted on the output end of the telescopic mechanism 4, and is controlled by the telescopic mechanism 4 to approach the interactive screen 2 for wiping, the telescopic mechanism 4 is fixedly mounted on the sliding mechanism 3, and is controlled by the sliding mechanism 3 to move up and down to wipe the interactive screen 2, an outer cover of the cleaning device is provided with a shell 12, and the shell 12 is fixedly mounted on the gantry 31 by screws, an entrance and exit 13 is provided on the right side of the shell 12 near the wall 1, the interactive screen 2 is slidably connected to the wall 1 by left and right slide rails 11, and when the interactive screen 2 needs to be cleaned, it enters the cleaning device through the entrance and exit 13 for cleaning.

[0039] Among them, the interactive screen 2 is located outside the shell 12 during normal operation. The interactive screen 2 slides on the left and right slide rails 11 through the touch screen operation of the interactive screen 2 by the experiencer. After the interaction is completed, the interactive screen 2 automatically enters the shell 12 from the entrance 13 on the right side of the shell 12. The cleaning device arranged inside the shell 12 cleans the screen of the interactive screen 2. The cleaning device includes a sliding mechanism 3, a telescopic mechanism 4 and a wiping mechanism 5. The wiping mechanism 5 is used to wipe the traces of dust, sweat, oil stains, fingerprints, etc. on the interactive screen 2. The telescopic mechanism 4 is used to control the wiping mechanism 5 to approach or move away from the interactive screen 2 so that the wiping mechanism 5 can contact the interactive screen 2 and wipe it. The sliding mechanism 3 controls the wiping mechanism 5 to move up and down to rub against the interactive screen 2 to wipe the screen. After the interactive screen 2 is cleaned, it slides out of the shell 12 from the entrance 13 and waits for the next interaction.

[0040] The wiping mechanism 5 includes a wiping bracket 51, an elastic strip 52, a cloth reel 53, a driving shaft 54, a driven shaft 57 and a wiping cloth 55. The wiping bracket 51 is fixedly connected to the output end of the telescopic mechanism 4. The elastic strip 52 is fixedly mounted on the wiping bracket 51, and the elastic strip 52 is located on the front of the interactive screen 2. The cloth reel 53 and the driving shaft 54 ​​are rotatably mounted on the inner side of the wiping bracket 51, and the cloth reel 53 and the driving shaft 54 ​​are respectively located obliquely above and obliquely below the elastic strip 52. The wiping cloth 55 is rolled up on the cloth reel 53, and after passing through the elastic strip 52, it is rotated by the driving shaft 54 ​​and the driven shaft 57 to release the cloth. The driving shaft 54 ​​is controlled to rotate by a motor. A wiping surface 56 is provided on the wiping cloth 55, and the wiping surface 56 is in contact with the front of the elastic strip 52. Two supporting rollers 58 for supporting the wiping cloth 55 are rotatably mounted on the inner side of the wiping bracket 51. The supporting rollers 58 are close to the elastic strip 52 and are respectively located obliquely above and obliquely below the elastic strip 52.

[0041] Among them, the elastic strip 52 is elastic, and the interactive screen 2 is squeezed by the elastic strip 52 to cause a slight deformation of the elastic strip 52, so that the wiping surface 56 can be close to the interactive screen 2 to wipe the screen, and the wiping cloth 55 is a non-woven fabric, which is rolled up on the cloth reel 53. When the wiping surface 56 needs to be replaced, the driving shaft 54 ​​is driven by the motor to rotate one circle, and the driving shaft 54 ​​drives the wiping cloth 55 to move downward through the driven shaft 57. The downward movement length of the wiping cloth 55 is the circumference of the driving shaft 54, wherein the circumference of the driving shaft 54 ​​is greater than the width of the wiping surface 56. Therefore, the wiping surface 56 can be completely replaced by one rotation of the driving shaft 54. When the driving shaft 54 ​​rotates, the cloth reel 53 releases the cloth at the same time, so that the unused wiping cloth 55 on the cloth reel 53 is attached to the elastic strip 52 to become a new wiping surface 56, and there is no need for manual frequent replacement or cleaning of the wiping surface 56.

[0042] A recovery bin 81 is provided at the lower end of the wiping bracket 51. After wiping, the wiping cloth 55 is folded into the recovery bin 81 through the recovery mechanism 8. The recovery mechanism 8 includes a turntable 82, a swing arm 83, a folding rod 84, a recovery slider 85 and a fixed column 86. Two turntables 82 are provided, which are respectively fixedly mounted at both ends of the driving shaft 54. An eccentric column 87 is provided on the outer end surface of the turntable 82. Two recovery sliders 85 are provided, which are respectively located at both ends of the folding rod 84. The folding rod 84 is slidably mounted in the slide grooves on both sides of the wiping bracket 51 through two recovery sliders 85. A swing arm groove 88 that runs through the swing arm 83 is provided on the swing arm 83. One end of the swing arm 83 is rotatably connected to the fixed column 86. The eccentric column 87 and the recovery slider 85 are both slidably connected to the swing arm groove 88.

[0043] Among them, the wiping surface 56 will be contaminated after wiping the interactive screen 2. The recycling bin 81 is used to recycle the used wiping cloth 55. When the wiping surface 56 is replaced, the motor controls the driving shaft 54 ​​to rotate one circle, so that the turntable 82 rotates one circle, so that the eccentric column 87 slides in the swing arm slot 88, and at the same time, the eccentric column 87 also drives the swing arm 83 to swing with the fixed column 86 as the center of the circle, so that the swing arm 83 drives the recovery slider 85 to slide in the slide grooves on both sides of the wiping bracket 51, and the recovery slider 85 is a reciprocating sliding action, so that the folding rod 84 performs a reciprocating horizontal movement inside the recovery bin 81. When the folding rod 84 moves back and forth, a gap is provided in the middle of the folding rod 84, and the wiping cloth 55 is located in the gap. When the folding rod 84 moves back and forth, the folding rod 84 folds the wiping cloth 55, that is, the driving shaft 54 ​​rotates one circle, the wiping surface 56 is replaced once, and the folding rod 84 folds the wiping cloth 55 once, so that the used wiping cloth 55 can be neatly folded in the recycling bin 81. When the wiping cloth 55 on the cloth reel 53 is used up, the wiping cloth 55 folded in the recycling bin 81 is taken out while replacing the cloth reel 53, and the used wiping cloth 55 can be cleaned for recycling.

[0044] A locking column 91 is provided at one end of the cloth reel 53, and the locking column 91 is controlled to be locked or freely rotated by a locking mechanism 9. The locking mechanism 9 includes a locking block 92 for fixing the locking column 91. A V-shaped groove 93 is provided at the upper end of the locking block 92. When the cloth reel 53 is locked, the inner side of the V-shaped groove 93 abuts against the outer diameter of the locking column 91. A lifting rod 94 is fixedly connected to the lower end of the locking block 92, and the lifting rod 94 is slidably installed on the outer side of the wiping bracket 51 up and down. A locking spring 95 is sleeved on the outer side of the lifting rod 94. A compression plate for compressing the locking spring 95 is provided on the lifting rod 94. When the lifting rod 94 rises, the locking spring 95 is compressed by the compression plate on the lifting rod 94. A second roller 96 is rotatably installed at the bottom of the lifting rod 94.

[0045] The locking mechanism 9 also includes an incomplete gear 97, which is located on one of the swing arms 83 and is rotatably connected to the fixed column 86. The incomplete gear 97 is meshed with a locking rack 98, and the locking rack 98 is slidably connected to the wiping bracket 51 through guide columns at both ends. A triangular block 99 for lifting the second roller 96 is provided on one side of the upper end of the locking rack 98. The upper end of the triangular block 99 is provided with a rounded corner. When the locking rack 98 slides, the triangular block 99 lifts or releases the second roller 96.

[0046] When wiping the interactive screen 2, the wiping surface 56 on the wiping cloth 55 rubs against the interactive screen 2, which will cause the wiping cloth 55 to drive the cloth reel 53 to rotate, causing the wiping cloth 55 to loosen, thereby affecting the wiping effect. In order to prevent the wiping cloth 55 from driving the cloth reel 53 to rotate, the cloth reel 53 is locked by the locking mechanism 9. During the wiping process of the interactive screen 2, the locking block 92 locks the locking column 91. When the wiping surface 56 is replaced, the motor controls the driving shaft 54 ​​to rotate one circle, so that the turntable 82 rotates one circle, so that the swing arm 83 swings with the fixed column 86 as the center, so that the incomplete gear 97 on one side of the swing arm 83 rotates, and the incomplete gear 97 rotates a certain angle and then rotates in the opposite direction. The locking rack 98 then moves back to the origin, causing the incomplete gear 97 to drive the locking rack 98 to move laterally, and the locking rack 98 moves laterally and then returns to its original position, i.e., performs a reciprocating motion. During the movement of the locking rack 98, the top of the triangular block 99 leaves the second roller 96. At this time, the separately compressed locking spring 95 rebounds the lifting rod 94 to cause the lifting rod 94 to drop, causing the locking block 92 to leave the locking column 91, so that the cloth reel 53 is in a free rotation state. Therefore, when the wiping surface 56 is replaced, the cloth reel 53 can rotate freely and release the cloth. After the wiping surface 56 is replaced, the locking rack 98 also completes a reciprocating motion, causing the triangular block 99 to lift the second roller 96 again, so that the locking block 92 locks the locking column 91.

[0047] The wiping cloth 55 is provided with cleaning liquid through the spraying mechanism 7. The spraying mechanism 7 is located below the interactive screen 2. The spraying mechanism 7 includes a spray box 71, a spray head 72, a spray water pump 73 and a liquid storage barrel 74. The spray box 71 is fixedly mounted on the wall 1 through a bracket. An opening is provided on one side of the spray box 71, and the opening direction is toward the elastic strip 52. There are several spray heads 72, which are evenly distributed on the inner bottom of the spray box 71, and the spraying direction of the spray head 72 is consistent with the opening direction of the spray box 71. The input end of the spray water pump 73 is connected to the liquid storage barrel 74 through a connecting pipe, and the output end is connected to the spray head 72 through a connecting pipe. Cleaning liquid is provided inside the liquid storage barrel 74. The liquid storage barrel 74 is made of transparent material and is fixed to the outside of the shell 12 through a bracket.

[0048] Among them, by setting up the spraying mechanism 7, the interactive screen 2 can be wet wiped and dry wiped. First, the wiping surface 56 is placed in the spray box 71, and then the cleaning liquid in the liquid storage barrel 74 is transported to the spray head 72 through the spray water pump 73, and then the wiping surface 56 on the wiping cloth 55 is evenly sprayed through multiple spray heads 72, and then the interactive screen 2 is wet wiped with the wiping surface 56 with the cleaning liquid. After the wet wiping is completed, the new wiping surface 56 is replaced and the interactive screen 2 is dry wiped again, which can improve the wiping efficiency and effect. The liquid storage barrel 74 is located outside the outer shell 12, which can facilitate the observation of the cleaning liquid inventory in the liquid storage barrel 74.

[0049] The sliding mechanism 3 includes a gantry 31, a lifting slide rail 32, a lifting skateboard 33, a lifting rack 34, a gear 35 and a lifting motor 36. The gantry 31 is vertically fixedly installed on the wall 1, and the interactive screen 2 is located on the inner side of the gantry 31. The lifting rack 34 is fixedly installed on the inner side of the gantry 31 and corresponds to the front of the interactive screen 2. There are two lifting slide rails 32, which are respectively located on both sides of the lifting rack 34. The lifting skateboard 33 is connected to the lifting slide rail 32 for up and down sliding. A gear rack is provided on the upper side of the lifting skateboard 33. The gear 35 is rotatably installed on the gear rack, and the gear 35 is meshed with the lifting rack 34. The gear 35 is driven to rotate by the lifting motor 36.

[0050] Among them, the wiping surface 56 can be moved up and down by the sliding mechanism 3 to realize wiping of the interactive screen 2, and the gear 35 is driven to rotate by the lifting motor 36, and the gear 35 is meshed and connected with the lifting rack 34 fixedly installed on the gantry 31, so that the lifting slide 33 can slide up and down on the two lifting rails 32, thereby driving the telescopic mechanism 4 and the wiping mechanism 5 to slide up and down.

[0051] The telescopic mechanism 4 includes a telescopic bracket 41, a telescopic rod 42 and a guide column 43. The telescopic bracket 41 is fixedly installed on the end surface of the lifting slide 33, the telescopic rod 42 is fixedly installed on the inner side of the telescopic bracket 41, and the output end of the telescopic rod 42 is fixedly connected to the back of the wiping bracket 51. Two guide columns 43 are provided on the back of the wiping bracket 51. The guide columns 43 pass through the telescopic bracket 41 and are slidably connected to the telescopic bracket 41.

[0052] When the interactive screen 2 is cleaned, the wiping mechanism 5 is driven by the telescopic rod 42 to approach the interactive screen 2, so that the elastic strip 52 squeezes the interactive screen 2. Therefore, the interactive screen 2 can be wiped by the wiping surface 56 attached to the front of the elastic strip 52. After wiping is completed, the wiping surface 56 is driven away from the interactive screen 2 again by the telescopic rod 42. The provision of two guide columns 43 can increase the stability of the telescopic mechanism 4.

[0053] Two limit brackets 101 are fixedly provided on the wall 1, and the two limit brackets 101 are respectively located on both sides of the interactive screen 2, and the front of the limit brackets 101 is higher than the display surface of the interactive screen 2. Pressure regulating mechanisms 10 are provided on both sides of the wiping bracket 51, and the pressure regulating mechanism 10 includes a first roller 102. When the wiping mechanism 5 wipes the interactive screen 2, the two first rollers 102 roll on the two limit brackets 101 respectively. The pressure regulating mechanism 10 also includes a pressure sensor 103, a pressure regulating slide 104 and a pressure regulating spring 105. The pressure regulating slide 104 is slidably installed on the outer side of the wiping bracket 51, one end of the pressure regulating slide 104 is connected to the pressure sensor 103 through the pressure regulating spring 105, and the other end of the pressure regulating slide 104 is rotatably connected to the first roller 102.

[0054] Among them, the pressure regulating mechanism 10 can control the squeezing force of the elastic strip 52 on the interactive screen 2 to prevent the display screen from being damaged by excessive squeezing force. When the interactive screen 2 is wiped, the telescopic mechanism 4 drives the wiping mechanism 5 close to the interactive screen 2. After the two first rollers 102 contact the two limit brackets 101, the first rollers 102 will squeeze the pressure regulating spring 105 through the pressure regulating slide plate 104, so that the pressure regulating spring 105 squeezes the pressure sensor 103. At the same time, the wiping surface 56 contacts the interactive screen 2 through the elastic strip 52, and the telescopic mechanism 4 continues to operate, so that the elastic strip 52 can be used to wipe the interactive screen 2. The strip 52 is slightly deformed, so that the wiping surface 56 can be close to the interactive screen 2, which can improve the wiping effect. At the same time, the pressure sensor 103 is continuously squeezed by the pressure adjusting spring 105, so that the pressure on the pressure sensor 103 becomes larger. The degree of deformation of the elastic strip 52, that is, the squeezing force of the elastic strip 52 on the interactive screen 2 can be adjusted by adjusting the pressure value. By adjusting the pressure value to a reasonable range, the traces of dust, sweat, oil stains, fingerprints, etc. on the interactive screen 2 can be wiped clean without damaging the interactive screen 2 due to excessive pressure.

[0055] The driven shaft 57 controls the distance between the driven shaft 57 and the driving shaft 54 ​​through the distance adjusting mechanism 6. The distance adjusting mechanism 6 includes a distance adjusting slider 61, a distance adjusting spring 62, an extrusion block 63, a threaded rod 64 and an adjusting knob 65. Two distance adjusting sliders 61 are provided, which are slidably installed in the slide grooves on both sides of the wiping bracket 51. The two ends of the driven shaft 57 are respectively rotatably connected with the two distance adjusting sliders 61. The threaded rod 64 is installed on the wiping bracket 51 through threads. One end of the threaded rod 64 is fixedly connected to the adjusting knob 65, and the other end is movably connected to the extrusion block 63. The two ends of the distance adjusting spring 62 are respectively fixedly connected to the extrusion block 63 and the distance adjusting slider 61.

[0056] Among them, the used wiping cloth 55 is located between the driving shaft 54 ​​and the driven shaft 57. The distance between the driving shaft 54 ​​and the driven shaft 57 is adjusted by the distance adjusting mechanism 6, so that the clamping force of the driving shaft 54 ​​and the driven shaft 57 on the wiping cloth 55, that is, the driving force, can be adjusted, and it is also convenient to replace the wiping cloth 55. By rotating the two adjusting knobs 65, the squeezing block 63 squeezes the distance adjusting spring 62, and the distance adjusting spring 62 squeezes the distance adjusting slider 61 so that the driven shaft 57 is close to the driving shaft 54, thereby adjusting the driving force on the wiping cloth 55. Rotating the adjusting knob 65 in the opposite direction makes the driven shaft 57 move away from the driving shaft 54, which can facilitate the replacement of the wiping cloth 55.

[0057] The working principle and use process of the present invention:

[0058] The interactive screen 2 is located outside the housing 12 during normal operation. The user operates the interactive screen 2 by touching the screen to make the interactive screen 2 slide on the left and right slide rails 11. After the interaction is completed, the interactive screen 2 automatically slides into the housing 12 from the entrance 13 on the right side of the housing 12. The wiping mechanism 5 is controlled by the sliding mechanism 3 to move to the spray box 71 position, and then the wiping surface 56 is allowed to enter the spray box 71 through the telescopic mechanism 4. Then, the cleaning liquid in the liquid storage barrel 74 is evenly sprayed on the wiping cloth 55 through the spray pump 73 and the spray head 72. Then, the wiping surface 56 is allowed to leave the spray box 71 through the telescopic mechanism 4. The wiping mechanism 5 is driven by the sliding mechanism 3 to approach the interactive screen 2, so that the elastic strip 52 squeezes the wiping surface 56, so that the wiping surface 56 is in close contact with the interactive screen 2. The pressure regulating mechanism 10 can adjust the squeezing force of the elastic strip 52 squeezing the interactive screen 2. Then, the sliding mechanism 3 drives the wiping surface 56 to move up and down to wet-wipe the interactive screen 2, so that the screen can be easily wiped. After wet wiping, the motor drives the drive shaft 54 ​​to rotate one circle, so that the used wiping surface 56 moves to the position of the drive shaft 54, and the unused wiping cloth 55 on the cloth reel 53 is attached to the elastic strip 52 to become a new wiping surface 56, and then the interactive screen 2 is dry-wiped again. Every time the motor controls the drive shaft 54 ​​to rotate one circle, the used wiping cloth 55 is folded once through the recycling mechanism 8, so that the used wiping cloth 55 can be Neatly folded in the recycling bin 81, the interactive screen 2 slides out of the housing 12 from the entrance 13 after cleaning, waiting for the next interaction. In addition, when wiping the interactive screen 2, the wiping surface 56 on the wiping cloth 55 rubs against the interactive screen 2, which will cause the wiping cloth 55 to drive the cloth reel 53 to rotate, causing the wiping cloth 55 to loosen, thereby affecting the wiping effect. In order to prevent the wiping cloth 55 from driving the cloth reel 53 to rotate, the locking mechanism 9 can intermittently lock the cloth reel 53.
