[0037] An accommodating space 7 is provided on the shell 1. The accommodating space 7 is recessed from the top surface of the shell 1. The accommodating space 7 does not penetrate the shell 1. The accommodating space 7 is used to accommodate the first grille 2, the second grille 3, the shaft 4, the substrate 5, the bent steel plate 6 and the external telescopic screen 112.

[0038] The telescopic screen 112 is attached to the bent steel plate 6. The structures of the telescopic screen 112 and the bent steel plate 6 are roughly the same. During the use of the telescopic screen 112 product, the telescopic screen 112 and the bent steel plate 6 are roughly U-shaped. One end of the bent steel plate 6 is located between one end of the telescopic screen 112 and the grid member, the middle of the bent steel plate 6 is located between the middle of the telescopic screen 112 and the middle of the shaft 4, and the other end of the bent steel plate 6 is located between the other end of the telescopic screen 112 and the substrate member 5.

[0039] One end of the bent steel plate 6 is arranged on the second grid member 3, and the first grid member 2 and the second grid member 3 form a first reference plane 8 for supporting one end of the bent steel plate 6. The middle part of the telescopic screen 112 is arranged around the side of the shaft body 4 away from the first grid member 2. The end of the substrate member 5 away from the first grid member 2 is provided with a second reference plane 9 for contacting the other end of the bent steel plate 6. The other end of the bent steel plate 6 is located between the second reference plane 9 and the shell 1. The first reference plane 8 is arranged parallel to the second reference plane 9. In this embodiment, the distance between the first reference plane 8 and the second reference plane 9 is the same as the diameter of the shaft body 4.

[0040] When the display area of ​​the telescopic screen 112 needs to be changed, the user drives the second grille 3 to slide relative to the shell 1. When the second grille 3 slides, it drives the bent steel plate 6 and the telescopic screen 112 to move together, thereby adjusting the display area of ​​the telescopic screen 112. During the extension and retraction of the telescopic screen 112, the bent steel plate 6 always supports the part of the telescopic screen 112 used to display the image. During the use of the telescopic screen 112, the telescopic screen 112 is prevented from being concave and damaged, thereby extending the service life of the telescopic screen 112.

[0041] The bent steel plate 6, the first reference plane 8, and the second reference plane 9 cooperate to ensure that the telescopic screen 112 is in a flat state, thereby preventing the telescopic screen 112 from being damaged during use due to its unevenness; through the setting of the shaft body 4, when the display area of ​​the telescopic screen 112 changes, the telescopic screen 112 maintains the same bending angle around the shaft body 4, thereby avoiding damage to the telescopic screen 112 due to changes in multiple different bending angles, thereby extending the service life of the telescopic screen 112.

[0042] See also Figures 1 to 4 As shown, the shell 1 is detachably connected to the protective shell 111, and the shaft body 4 is located between the protective shell 111 and the shell 1. The protective shell 111 is used to cover the middle part of the telescopic screen 112 which is arranged around the shaft body 4 away from the first grid member 2. The protective shell 111 is used to protect the bent part of the telescopic screen 112 to avoid damage to the bent part of the telescopic screen 112; at the same time, the bending angle of the telescopic screen 112 is limited to ensure that the telescopic screen 112 is always extended and retracted at the same bending angle during the extension and retraction process.

[0043] The shell 1 is provided with two sound holes 11 connected with the accommodating space 7 and penetrating the side wall of the shell 1 , and the shaft body 4 is provided with a through hole 12 penetrating the shaft body 4 , the through hole 12 is connected with one of the sound holes 11 , and the other sound hole 11 is used to transmit sound.

[0044] During the use of the retractable screen 112 product, the outside air flows through the sound outlet holes 11 and the perforations 12 to achieve heat dissipation of the retractable screen 112 product and extend the service life of the retractable screen 112 product. The sound of the retractable screen 112 product when in use is diffused through the sound outlet holes 11. Of course, the vibration generated by the sound emitted by the retractable screen 112 product through the sound outlet holes 11 can also assist the air flow, thereby improving the heat dissipation effect of the sound outlet holes 11. Preferably, the number of sound outlet holes 11 is multiple, and multiple sound outlet holes 11 are provided on both sides of the housing 1 that are away from each other.

[0045] See also Figures 1 to 5As shown, the shaft body 4 includes a cylindrical barrel 13 and two protruding shafts 14. The central axis of the cylindrical barrel 13 and the central axis of the protruding shaft 14 are arranged to coincide with each other. The two ends of the cylindrical barrel 13 are respectively rotatably sleeved on the outside of the two protruding shafts 14. The two protruding shafts 14 are respectively arranged on the two ends of the housing 1. The two protruding shafts 14 are both located in the accommodating space 7. The middle part of the bent steel plate 6 and the middle part of the telescopic screen 112 are both wound around the outside of the cylindrical barrel 13 away from the first grid member 2. Preferably, a flexible layer is sleeved on the outside of the cylindrical barrel 13, the bent steel plate 6 is located between the telescopic screen 112 and the flexible layer, and the flexible layer contacts the bent steel plate 6 to reduce the noise generated when the bent steel cylinder and the cylindrical barrel 13 rotate relative to each other.

[0046] The cylindrical tube 13 has a column part 15 and column edges 16 respectively arranged at both ends of the column part 15. The outer diameter of the column edge 16 is larger than the outer diameter of the column part 15. The middle part of the bent steel plate 6 and the middle part of the telescopic screen 112 are arranged around the outer side of the column part 15 away from the first grid member 2. The column edges 16 at both ends of the column part 15 are used to stop and limit the two sides of the middle part of the bent steel plate 6 and the two sides of the middle part of the telescopic screen 112. During the use of the telescopic screen 112 product, the column edges 16 at both ends of the column part 15 are used to stop and limit the bent steel plate 6 and the telescopic screen 112, so as to prevent the bent steel plate 6 and the telescopic screen 112 from moving along the axial direction of the shaft body 4, thereby improving the use performance of the telescopic screen 112 product.

[0047] The second grille 3 is provided with a slide groove 17, and the length direction of the slide groove 17 is parallel to the length direction of the grille. The shell 1 is provided with a guide rail 18 located in the accommodating space 7, and the guide rail 18 and the slide are accommodated in the slide groove 17. During the relative sliding process of the second grille 3 and the shell 1, the sliding direction of the second grille 3 is limited by the cooperation of the guide rail 18 and the slide groove 17 to prevent the second grille 3 from being skewed during the sliding process.

[0048] The guide rail 18 is provided with a damping assembly 19, which is used to increase the friction between the housing 1 and the second grille 3, so that the second grille 3 is positioned on the housing 1 after sliding. During the extension and retraction process of the telescopic screen 112, when the display area of ​​the telescopic screen 112 reaches a preset value, the user no longer drives the second grille 3, and the second grille 3 and the housing 1 no longer move relative to each other via the damping assembly 19. The damping assembly 19 is provided to prevent the display area of ​​the telescopic screen 112 from changing due to vibration or the like.

[0049] The damping assembly 19 includes an elastic member 21 and a ball 22. In this embodiment, the elastic member 21 is a spring. A receiving hole is provided on the guide rail 18. The elastic member 21 and the ball 22 are both located in the receiving hole. A plurality of pits are provided on the shell 1. The plurality of pits are arranged in a collinear manner. The plurality of pits are arranged along the length direction of the slide groove 17. The pits are recessed from the inner groove wall of the slide groove 17. Under the action of elastic force, the elastic member 21 drives the ball 22 to protrude out of the outer surface of the guide rail 18 and extend into the pits.

[0050] When the display area of ​​the telescopic screen 112 reaches a preset value, the elastic member 21 drives the ball 22 to protrude out of the outer surface of the guide rail 18 and enter the pit under the action of elastic force, and the inner pit wall of the pit is used to resist the limiting ball 22, thereby increasing the friction between the second grid member 3 and the housing 1, thereby positioning the second grid member 3 on the housing 1. Through the arrangement of the ball 22, during the sliding process of the second grid member 3 and the housing 1, the ball 22 and the second grid member 3 are rolled, reducing the wear of the second grid member 3 and the damping assembly 19, and reducing friction noise.

[0051] See also Figures 1 to 8 As shown, the first grille 2 is provided with a plurality of first grilles 23 spaced apart and arranged in parallel, the first grilles 23 are generally in the shape of straight strips, and the cross-sectional shape of the first grilles 23 is generally in the shape of a rectangle. The second grille 3 is provided with a first blind groove 24 and a plurality of second grilles 25 located in the first blind groove 24, the second grilles 25 have the same structure as the first grilles 23, the second grilles 25 are connected to the bottom wall of the first blind groove 24, the plurality of second grilles 25 are spaced apart and arranged in parallel, and the plane of the first grille 23 away from the bottom wall of the first blind groove 24 and the plane of the second grille 25 away from the bottom wall of the first blind groove 24 form a first reference plane 8.

[0052] When the first grid member 2 is plugged into the second grid member 3, the first grid 23 is accommodated in the first blind groove 24, and the first grid 23 and the second grid 25 are staggered, that is, there is a second grid 25 between any two adjacent first grids 23, and there is a first grid 23 between any two adjacent second grids 25.

[0053] During the use of the retractable screen 112 product, according to the size of the display area of ​​the retractable screen 112 required by the user, the user drives the second grille 3 to slide relative to the shell 1, thereby changing the area of ​​the first reference plane 8 formed by the first grille 23 and the second grille 25 supporting the retractable screen 112. When the second grille 3 slides, it drives the retractable screen 112 to retract, thereby adjusting the size of the display area of ​​the retractable screen 112. When the display area of ​​the retractable screen 112 changes, the first grille 23 and the second grille 25 always support the retractable screen 112 via the bent steel plate 6, so as to prevent the retractable screen 112 from being concave and poorly used when the user presses the retractable screen 112 with his fingers, thereby ensuring the stability of the performance of the retractable screen 112.

[0054] The second grid member 3 has a second blind groove 26, which is recessed from the lower surface of the second grid member 3. The first blind groove 24 and the second blind groove 26 are recessed from the upper and lower sides of the second grid member 3 which are far away from each other. The second blind groove 26 is used to accommodate control elements of the retractable screen 112 type product.

[0055] In actual use, the control element of the telescopic screen 112 type product is installed in the second blind groove 26, and the inner groove wall around the second blind groove 26 is used to protect the control element, thereby reducing the risk of damage to the control element due to collision. Of course, when the control element is damaged, the second grid member 3 can be pulled out from the housing 1, and then the control element in the second blind groove 26 can be repaired, thereby improving the maintenance efficiency of the control element and reducing the use and maintenance cost of the control element.

[0056] The shell 1 is provided with a clearance groove 27, which passes through the lower surface and the side surface of one end of the shell 1. The second grille 3 is provided with a retaining block 28 exposed in the clearance groove 27. The user drives the retaining block 28 to make the second grille 3 enter and exit the accommodating space 7.

[0057] When the display area size of the retractable screen 112 needs to be changed, the user's fingers enter the make way slot 27, pinch or hook the holding block 28 with the fingers, and then drive the second grille 3 to move relative to the shell 1, so that the second grille 3 enters and exits the shell 1, ensuring that the grilles of the first grille 2 and the second grille 3 can support retractable screens 112 of various area sizes.
