[0025] Embodiment:

[0026] Refer to Figure 1 - Figure 1 -5, a portable college English learning aid disclosed by the present utility model includes a display panel 1, characterized in that two staggered sliding grooves 2 are opened on both sides of the upper end of the display panel 1, sliding rods 3 are arranged inside the sliding grooves 2, one end of each sliding rod 3 is fixedly provided with a damping hinge 4, one end of the damping hinge 4 away from the sliding rod 3 is provided with an extension link 5, and one end of the extension link 5 is fixedly provided with a protective housing 6.

[0027] In this embodiment, the sliding grooves 2 are provided for installing the sliding rods 3, the damping hinges 4 and the sliding rods 3, and the sliding rods 3 are fixedly connected to the protective housing 6. Since two sliding grooves 2 are provided on both sides of the upper end of the display panel 1 and the sliding grooves 2 are staggered, the directions of the sliding rods 3, the damping hinges 4 and the extension links 5 inside the two sliding grooves 2 are opposite, so protective housings 6 are provided on both sides of the display panel 1;

[0028] When the learning aid is not in use, the two protective housings 6 are respectively sleeved on both sides of the display panel 1 to protect the display panel 1 from being collided or the like;

[0029] When the learning aid is in use, the two protective housings 6 are respectively pulled out to both sides, so that the damping hinges 4 extend out of the sliding grooves 2, and then bent through the damping hinges 4, so that the two protective housings 6 are deflected downward, and the lower ends of the side walls of the protective housings 6 are in contact with the lower side of the display panel 1 to form a bracket, as Figure 1 At this time, the display panel 1 is parallel to the horizontal plane, which is convenient for holding and taking.

[0030] Alternatively, the two protective cases 6 can be pulled out to both sides respectively, and the damping hinge 4 extends out of the sliding groove 2. At this time, one of the protective cases 6 is bent through the damping hinge 4 so that the lower end of the side wall of this protective case 6 is in contact with the display panel 1 to form a bracket, as Figure 2 , at this time, the display panel 1 forms an angle with the horizontal plane, so as to facilitate placing the device on the desktop for use;

[0031] In summary, the English learning device in this application can simultaneously meet the characteristics of being portable, easy to unfold, convenient to use, and strong in applicability.

[0032] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, rubber pads 7 are provided on both the bottom surface and the arc surface of the protective case 6, and transverse grooves 8 are provided on the outer surfaces of the rubber pads 7.

[0033] In this embodiment, through the arrangement of the rubber pads 7 and the transverse grooves 8, when the device is placed on the desktop for use, as shown in the figure, due to the inclination of the device body, the friction between the device and the desktop can be effectively increased through the transverse grooves 8, thereby achieving the effect of improving the stability of the device.

[0034] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, when the display panel 1 is inserted into the protective case 6, the outer wall of the display panel 1 fits against the inner wall of the protective case 6.

[0035] In this embodiment, since the outer wall of the display panel 1 fits against the inner cavity wall of the protective case 6, the stability of the display panel 1 in the protective case 6 can be improved, thereby achieving the purpose of improving the protection effect on the display panel 1.

[0036] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, connecting insertion rods 9 are provided at both ends of one side of one of the protective cases 6, and insertion rod grooves 10 are provided at positions corresponding to the connecting insertion rods 9 on one side of the other protective case 6.

[0037] In this embodiment, the connecting insertion rods 9 and the insertion rod grooves 10 are provided to connect the two protective cases 6 to each other, so as to avoid the problem that the two protective cases 6 are opened under the influence of gravity, and further improve the protection of the display panel 1.

[0038] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, a limit convex block 11 is provided on one side of the sliding rod 3, and a limit groove 12 that is slidably matched with the limit convex block 11 is provided on the inner groove wall of the sliding groove 2.

[0039] In this embodiment, through the arrangement of the limiting groove 12 and the limiting bump 11, it can effectively prevent the sliding rod 3 from being pulled out when the protective housing 6 is pulled out, achieving the purpose of limiting the sliding rod 3.

[0040] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, an elastic plate 13 is provided at the junction of the inner cavity of the protective housing 6 and the insertion rod groove 10.

[0041] In this embodiment, through the arrangement of the elastic plate 13, the display panel 1 is retracted, and the two protective housings 6 are closed with each other, so that the connecting insertion rod 9 is inserted into the insertion rod groove 10. The connecting insertion rod 9 cooperates with the side wall of the display panel 1 to squeeze the elastic plate 13, causing the elastic plate 13 to deform, so as to increase the friction between the insertion rod groove 10 and the connecting insertion rod 9, and improve the friction between the protective housing 6 and the display panel 1, achieving the problem of preventing the protective housing 6 from falling off automatically.

[0042] The implementation principle of the above embodiment is: during use, the two protective housings 6 are respectively pulled out to both sides, so that the damping hinge 4 extends out of the sliding groove 2, and then the protective housing 6 is bent through the damping hinge 4. By changing the bending angles of the two protective housings 6, the angle of the display panel 1 can be adjusted, enabling the learning aid to be applicable to different scenarios and achieving the effect of improving the practicability of the learning aid;

[0043] Moreover, through the arrangement of the sliding rod, the damping hinge and the extension connecting rod, the closing and opening speeds of the protective housing can be effectively increased, and the convenience of the device during use can be effectively improved.

[0044] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model should be covered within the protection scope of the present utility model.
