[0055] Many electronic product packaging designs want to be able to see the product inside the box as soon as it is picked up. Generally, plastic sheets are used, mainly PET materials, to make plastic sheets, open windows on the color boxes, and then stick the PET plastic sheets on the color box windows. Not only can you see what the product looks like when you pick up the box, but the plastic window can also prevent foreign objects from falling into the box during production and transportation, protecting the product's functions. However, due to the plastic bans issued around the world and the goal of achieving full plastic elimination by 2025, plastic has become a product that designers want to use but cannot use. Using opaque packaging boxes instead will not allow consumers to see the product directly.

[0056] Among modern young people, playing games has become a part of life. Major game companies have launched consoles one after another. When playing computer games, many gamers will choose to use highly operable game controllers to match them, and only game controllers can be operated on the adapted game consoles.

[0082] In this embodiment, if Figures 1 to 15 As shown, the extension rail 162 is connected to the slide rail 161 , and the structure of the extension rail 162 is similar to that of the slide rail 161 . For example, the extension rail 162 and the slide rail 161 are both structures such as slide cavities, slide grooves or rails, which are not limited here.

[0083] It can be understood that by respectively arranging extension rails 162 on the two side panels 16, and making the extension rails 162 be arranged adjacent to the second end 1612 of the slide rail 161 and connected with the slide rail 161, the extension rails 162 can be used to provide an avoidance or extension area for the cover 2 during rotation, so that the cover 2 will not interfere with the two ends of the front panel 12 during rotation, and will not affect the stability of the placement of the packaging box 100 after rotation.

[0084] In this embodiment, when the packaging box 100 is in an open state, in order to prevent the cover plate 2 from interfering with or affecting the opening 121, the cover plate 2 is rotated so that the cover plate 2 has a rotational state rotating around the pin shaft 3 and a contact state in which the cover plate 2 contacts the top panel 14 and / or the bottom panel 15.

[0085] It can be understood that when the extension rail 162 provides an extension area for the cover plate 2 during rotation, the radius of rotation of the cover plate 2 around the pin shaft 3 is the same as the distance from the pin shaft 3 to the two ends of the front panel 12, that is, the radius of rotation of the cover plate 2 around the pin shaft 3 is the same as the distance from the two ends of the front panel 12 when the pin shaft 3 is located on the track 161. In this way, in order for the cover plate 2 to smoothly pass over the two ends of the front panel 12 when it is in a rotating state, the pin shaft 3 is located on the extension rail 162, that is, the extension rail 162 provides an extension area for the cover plate 2. In order for the cover plate 2 to abut against the top panel 14 and / or the bottom panel 15 when the cover plate 2 is in an abutting state to affect the stability of the placement of the packaging box 100, the pin shaft 3 is located on the slide rail 161.

[0086] Of course, the extension rail 162 provides an escape area for the cover plate 2 during the rotation process. At this time, the radius of the cover plate 2 rotating around the pin shaft 3 is the same as the distance from the pin shaft 3 to the two ends of the front panel 12, that is, the radius of the cover plate 2 rotating around the pin shaft 3 is the same as the distance from the two ends of the front panel 12 when the pin shaft 3 is located on the extension rail 162. In this way, in order for the cover plate 2 to smoothly pass over the two ends of the front panel 12 when it is in the rotating state, the pin shaft 3 is located on the slide rail 161. In order for the cover plate 2 to abut against the top panel 14 and / or the bottom panel 15 when it is in the abutting state to affect the stability of the placement of the packaging box 100, the pin shaft 3 is located on the extension rail 162, that is, at this time, the extension rail 162 provides an escape area for the cover plate 2.

[0087] In one embodiment, if Fig.13 and Fig.14 As shown, the extension rail 162 may be optionally arranged in an arc shape, as long as the cover plate 2 can rotate around the pin shaft 3 when the cover plate 2 is in a rotating state and can smoothly pass over the two ends of the front panel 12, which is not limited here.

[0088] In another embodiment, if Figure 1 and Fig.12As shown, the extension rail 162 is arranged in a straight line, and the extension direction of the extension rail 162 is arranged at an angle to the extension direction of the slide rail 161. Optionally, the extension direction of the extension rail 162 is arranged perpendicular to the extension direction of the slide rail 161, which is not limited here.

[0089] In one embodiment, if Figures 1 to 14 As shown, the extension rail 162 includes a first section 1621 and a second section 1622 . The first section 1621 and the second section 1622 are both connected to the slide rail 161 and are located at opposite sides of the slide rail 161 .

[0090] Alternatively, if Figure 12 to Figure 14 As shown, the first section 1621 and the second section 1622 are both connected to the second end 1612 and are symmetrically arranged. Of course, in other embodiments, such as Figures 1 to 11 As shown, the first section 1621 and the second section 1622 are both adjacent to the second end 1612 and are staggered, which is not limited here.

[0091] In one embodiment, the cover plate 2 includes a first cover plate 21 and a second cover plate 22, the pin shaft 3 includes a first pin shaft and a second pin shaft, the slide rail 161 is provided with a slide groove and a partition 1613 provided in the slide groove, the partition 1613 divides the slide groove into a first slide groove 1614 and a second slide groove 1615 provided in parallel, the first cover plate 21 is slidably connected to the first slide groove 1614 through the first pin shaft, and the second cover plate 22 is slidably connected to the second slide groove 1615 through the second pin shaft; wherein, in the closed state, In the closed state, the first pin and the second pin are both located at the first end 1611, and the first cover plate 21 and the second cover plate 22 cooperate to cover the opening 121; in the open state, the first pin and / or the second pin are located at the second end 1612, and the first cover plate 21 and / or the second cover plate 22 rotate around the first pin and / or the second pin in the first slide groove 1614 and / or the second slide groove 1615, so that the first cover plate 21 and / or the second cover plate 22 are opposite to the top panel 14 and / or the bottom panel 15.

[0092] In this embodiment, if Figures 1 to 8 As shown, by providing two cover plates 2, namely, a first cover plate 21 and a second cover plate 22, the operation of the cover plate 2 can be easily realized. At the same time, by utilizing the gravity factor of the cover plate 2 itself, after the first cover plate 21 and the second cover plate 22 of the cover plate 2 are rotated, the first cover plate 21 / the second cover plate 22 is closely attached to the top panel 14 and / or the bottom panel 15, which can improve the stability of the packaging box 100.

[0093] It can be understood that the two ends of the first cover plate 21 are slidably disposed in the first slide groove 1614 through two first pin shafts, and the two ends of the second cover plate 22 are slidably disposed in the second slide groove 1615 through two second pin shafts.

[0094] In this embodiment, when the packaging box 100 is in a closed state, the first cover plate 21 and the second cover plate 22 drive the first pin shaft and the second pin shaft to move along the slide rail 161, so that the first pin shaft and the second pin shaft are both located at the first end 1611 of the slide rail 161, so that the first cover plate 21 and the second cover plate 22 cooperate to cover the opening 121.

[0095] It can be understood that when the packaging box 100 is in the open state, the first cover plate 21 and the second cover plate 22 can simultaneously drive the first pin shaft and the second pin shaft to move along the slide rail 161, so that the first pin shaft and the second pin shaft are both located at the second end 1612 of the slide rail 161. At this time, the first cover plate 21 and the second cover plate 22 can simultaneously rotate around the first pin shaft and the second pin shaft in the first slide groove 1614 and the second slide groove 1615, so that the first cover plate 21 and the second cover plate 22 are opposite to the top panel 14 and / or the bottom panel 15, that is, the first cover plate 21 and the second cover plate 22 are opposite to and abut against the top panel 14; or, the first cover plate 21 and the second cover plate 22 are opposite to and abut against the bottom panel 15; or, the first cover plate 21 is opposite to and abuts against the top panel 14, and the second cover plate 22 is opposite to and abuts against the bottom panel 15; or, the first cover plate 21 is opposite to and abuts against the bottom panel 15, and the second cover plate 22 is opposite to and abuts against the top panel 14, which is not limited here.

[0096] Of course, it is also possible that one of the first cover plate 21 and the second cover plate 22 (i.e. the first cover plate 21 or the second cover plate 22) first rotates around the first pin shaft / the second pin shaft in the first slide groove 1614 / the second slide groove 1615 to make the first cover plate 21 / the second cover plate 22 relative to and abut against the top panel 14 / the bottom panel 15; then, the other of the first cover plate 21 and the second cover plate 22 (i.e. the first cover plate 21 or the second cover plate 22) first rotates around the first pin shaft / the second pin shaft in the first slide groove 1614 / the second slide groove 1615 to make the first cover plate 21 / the second cover plate 22 relative to and abut against the top panel 14 / the bottom panel 15, and no limitation is made here.

In this embodiment, the side cover plate 24 can be arranged in a triangular shape. The side cover plate 24 can be arranged in a right triangle shape.

[0108] Understandable, such as Figures 1 to 8 As shown, the side cover plate 24 is defined to have a first right-angled side 241, a second right-angled side 242 and a hypotenuse 243 connected end to end. In this embodiment, the width of the front cover plate 23 is equal to the first right-angled side 241. Optionally, the angle between the first right-angled side 241 and the hypotenuse 243 is 60°, and the length of the first right-angled side 241 is 1 / 2 of the length of the hypotenuse 243.

Optionally, the vertical distance from the first end 1611 of the slide rail 161 to the connection between the top panel 14 and the front panel 12 is equal to the length of the second right-angled side 242.

[0110] It should be noted that the shape and length of the side cover plate 24 and the size setting of the slide rail 161 can be calculated and designed according to the length, width and height of the box body 1 and the size of the opening 121 based on mathematical principles such as trigonometric functions, and the style of the slide rail 161 is not limited here. In this embodiment, when the side cover plate 24 is a right-angled triangle, when the cover plate 2 (the first cover plate 21 / the second cover plate 22) rotates around the pin 3, the rotation radius of the cover plate 2 is equal to the length of the second right-angled side 242 of the side cover plate 24.

Then the length A1 of the hypotenuse 243 of the side cover 24 of the cover 2 is A=A, and the length D of the second right-angled side 242 of the side cover 24 is cosα*A1. Then the rightmost point of the slide rail 161 can be determined. In order to minimize the length of the cover plate 3 and minimize the cost, when the cover plate 2 rotates around the pin 3, the length of the second right-angled side 242 of the side cover plate 24 is tangent to the vertex where the front panel 12 and the top panel 14 are connected, the minimum size of the side cover plate 24 of the cover plate 2 can be calculated, the overall height of the box body 1 is generally C, and the length of the second right-angled side 242 of the side cover plate 24 is defined to be tangent to the vertex where the front panel 12 and the top panel 14 are connected, the angle formed by the second right-angled side 242 and the front panel 12 is β, according to cosβ=C / D, the distance from the front panel 12 to the leftmost end of the slide rail 161 is defined as B, the angle of β can be obtained, sinβ=B / D, the value of B can be calculated, and the leftmost point of the guide rail can also be determined.
