Abstract
Description
Technical Field
[0001] This invention relates to the field of head-mounted device technology, and more particularly to a head-mounted device packaging box. Background Technology
[0002] The outer packaging of VR headsets and other head-mounted devices is generally a standard square box. Taking VR headsets as an example, a VR headset consists of the main unit and a strap. The two ends of the strap connect to the main unit, which is then worn on the user's head. The box has an opening on one side. When placing the VR headset inside, the strap is first slightly rolled up, then placed against the main unit before being inserted into the box along with the headset through the opening on one side. Because the box only has one opening, the user cannot directly see how the VR headset is positioned inside. Furthermore, the lack of a restraining structure inside the box allows the VR headset to easily move around within the box. When removing the VR headset, it is pulled out through the opening on one side of the box, and the strap is prone to becoming tangled after removal.
[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0015] In some embodiments of this application, the second box body is provided with a clearance groove, which is used to make way for the main body of the device when the packaging box is closed.
[0016] In some embodiments of this application, the first box body has notches on two opposite side walls, the notches are directly opposite and communicate with the second receiving groove, and the strap assembly placed in the second receiving groove is exposed from the notches;
[0017] The second box body is provided with two fourth protrusions, and when the packaging box is closed, the fourth protrusions fit into the notch.
[0018] In some embodiments of this application, the rotatable connection position between the first box body and the second box body is located in the middle of one side of the packaging box, and when the packaging box is in the open state, the first box body and the second box body are laid flat on the same plane.
[0019] In some embodiments of this application, the packaging box further includes a fixing part for stopping the first box body and the second box body in the closed position.
[0020] In some embodiments of this application, the packaging box further includes a sleeve with open ends, and the first box body and the second box body are placed inside the sleeve after being closed.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0052] Packaging box structure reference Figures 1 to 8 The packaging box comprises a box body 10, a sleeve 20, and a fixing part 30, etc. Figure 1 This is a schematic diagram showing the structure of the packaging box body 10 placed inside the sleeve 20. Figure 2 This is a schematic diagram of the structure of the packaging box body 10 after it is closed. Figures 3 to 5 This is a diagram illustrating the process of opening the packaging box. Figures 6 to 8 This is a schematic diagram of the structure of the packaging box body 10 when it is opened.
[0053] The packaging box body 10 is used to store the head-mounted device 300, and it is the main part of the packaging box. The cover 20 is used to store the packaging box body 10 in the closed state. The fixing part 30 is used to keep the packaging box body 10 in the closed state.
[0054] Reference Figures 6 to 8 The packaging box body 10 includes a first box body 100 and a second box body 200. The first box body 100 and the second box body 200 are rotatably connected, and the second box body 200 is flipped to one side of the first box body 100 to open the packaging box. Figure 2 The diagram shown is a structural schematic of the first box 100 and the second box 200 after they are closed. Figure 6 The diagram shows the structure of the first box 100 and the second box 200 after they are opened.
[0055] The first housing 100 has a receiving slot 110 for placing the head-mounted device 300. The top of the first housing 100 is open to expose the head-mounted device 300 placed in the receiving slot 110. The receiving slot 110 includes a first receiving slot 111 and a second receiving slot 112 that are connected. The first receiving slot 111 is used to place the device body 310, and the second receiving slot 112 is used to place the strap assembly 320.
[0056] The second box 200 is used to close or open the receiving slot 110.
[0057] When placing the head-mounted device 300 into the packaging box 10, first flip the second box 200 to one side of the first box 100 to achieve... Figure 6 As shown, the receiving slot 110 is fully open and visible. Place the head-mounted device 300 into the receiving slot 110 from top to bottom, and then flip the second box 200 so that the second box 200 is fastened to the first box 100. The second box 200 closes the receiving slot 110, and the placement of the head-mounted device 300 is complete.
[0058] When removing the head-mounted device 300 from the main packaging box 10, first flip the second box 200 towards one side of the first box 100 to open it. Figure 6 In the state shown, the receiving slot 110 is fully open and visible, so the head-mounted device 300 is also fully visible. The user can simply lift the head-mounted device 300 upwards to remove it from the receiving slot 110.
[0059] When the first box 100 and the second box 200 in the main body of the packaging box 10 are opened, the receiving slot 110 for placing the head-mounted device 300 is fully exposed and visible. On the one hand, it is convenient to put the head-mounted device 300 directly into the receiving slot 110 from top to bottom, and can intuitively show the user the placement of the head-mounted device 300 in the packaging box. On the other hand, it is also convenient to lift the head-mounted device 300 directly from the receiving slot 110 and take it out.
[0060] Furthermore, unlike the common method of opening the packaging box from one side port in the prior art, the flip connection between the first box 100 and the second box 200 in this embodiment provides users with a brand-new way of opening the box and improves the user experience.
[0061] In some embodiments of this application, the head-mounted device 300 is placed in the receiving slot 110 at an angle to better show the user the placement of the head-mounted device 300 in the receiving slot 110.
[0062] In some embodiments of this application, reference is made to Figure 6 The first box 100 has a bottom wall and four side walls on the four sides of the bottom wall. The bottom wall and the four side walls of the first box 100 form an inner cavity of the first box 100, and the top of the inner cavity is open.
[0063] The inner cavity of the first box 100 is provided with a first protrusion 120, and a first receiving groove 111 is formed between the first protrusion 120 and one of the inner side walls of the first box 100, and a second receiving groove 112 is formed between the first protrusion 120 and the remaining inner side walls of the first box 100.
[0064] When the head-mounted device 300 is placed in the receiving groove 110, the first protrusion 120 is located in the area enclosed by the device body 310 and the strap assembly 320 to limit the head-mounted device 300, improve the stability of the head-mounted device 300 in the receiving groove 110, and prevent the head-mounted device 300 from moving.
[0065] The sidewalls forming the first receiving groove 111 are adapted to the outer shape of the equipment body 310 to improve the stability of the equipment body 310.
[0066] In some embodiments of this application, the second receiving groove 112 includes a connected second receiving groove I 1121 and two second receiving grooves II 1122. The second receiving groove I 1121 is disposed opposite to the first receiving groove 111. The two second receiving grooves II 1122 are disposed on both sides of the second receiving groove I 1121 and are connected to the first receiving groove 111. The second receiving groove I 1121 is used to place the adjustment part 321. One of the second receiving grooves II 1122 is used to place the left strap 322, and the other second receiving groove II 1122 is used to place the right strap 323.
[0067] The first receiving slot 111 and the second receiving slot 112 form a closed-loop slot structure. The main body 310, the adjustment part 321, the left strap 322, and the right strap 323 each have their own dedicated placement area, allowing the head-mounted device 300 to be placed in a relaxed state within the receiving slot 110. On the one hand, this avoids mutual compression between the components of the head-mounted device 300 during placement; on the other hand, it effectively avoids the problem of strap tangling when the head-mounted device 300 is taken out of the packaging box.
[0068] In some embodiments of this application, the sidewalls forming the second accommodating groove I are adapted to the outer contour of the adjustment part 321 to improve the placement stability of the adjustment part 321.
[0069] Since the adjustment part 321 is combined with the user's head when the head-mounted device 300 is worn, the outer contour of the adjustment part 321 is generally arc-shaped. Correspondingly, the second receiving groove I1121 is also arc-shaped to better accommodate the adjustment part 321.
[0070] In some embodiments of this application, reference is made to Figure 7 The bottom wall of the first receiving groove 111 is higher than the bottom wall of the second receiving groove Ⅰ1121. When the head-mounted device 300 is placed in the receiving groove 110, the placement position of the device body 310 is higher than the placement position of the adjustment part 321, so that the head-mounted device 300 is tilted as a whole, so as to better show the user the placement of the head-mounted device 300 in the receiving groove 110.
[0071] In some embodiments of this application, reference is made to Figures 6 to 8 The first protrusion 120 is provided with a recess 121.
[0072] The second box 200 is provided with a second protrusion 210. When the second box 200 is flipped toward the first box 100 to close the packaging box, the second protrusion 210 and the recess 121 are engaged, which improves the closure reliability between the first box 100 and the second box 200, further ensuring the stability of the head-mounted device 300 placed in the packaging box and avoiding damage to the device due to shaking.
[0073] In some embodiments of this application, the second box body 200 is provided with a third protrusion 220. When the packaging box is in the closed state, the third protrusion 220 is embedded in the second receiving groove 112 to limit the strap assembly 320.
[0074] Specifically, the third protrusion 220 is embedded in the second receiving groove I1121 to limit the adjustment part 321. Since the outer shell of the adjustment part 321 is generally rigid, limiting the adjustment part 321 by the third protrusion 220 effectively prevents the adjustment part 321 from moving within the second receiving groove I1121. The left strap 322 and the right strap 323 are generally made of soft material, so there is no need to set additional limiting structures to limit the left strap 322 and the right strap 323.
[0075] In some embodiments of this application, the second box 200 is provided with a clearance groove 240, which is used to make way for the device body 310 when the packaging box is closed.
[0076] After the head-mounted device 300 is placed in the receiving slot 110, since the main body of the device 310 is generally large, the top of the main body of the device 310 will be exposed when it is placed in the first receiving slot 111. The top of the main body of the device 310 is made room by the clearance slot 240, which is also equivalent to wrapping and limiting the top of the main body of the device 310. On the one hand, it helps to improve the stability of the placement of the main body of the device 310, and on the other hand, it also helps to reduce the thickness of the packaging box body 10.
[0077] In some embodiments of this application, the first housing 100 has notches 130 on two opposite side walls, and the notches 130 are directly connected to the second receiving groove 112. The strap assembly 320 placed in the second receiving groove 112 protrudes from the notches 130. Specifically, the notches 130 are connected to the second receiving groove 1122, and the left strap 322 and the right strap 323 protrude from the notches 130 on the corresponding sides.
[0078] The second box body 200 is provided with two fourth protrusions 230. When the packaging box is closed, the fourth protrusions 230 fit into the notch 130 to close the notch 130 and also cover the left tie 322 and right tie 323 inside.
[0079] After the first box 100 and the second box 200 are opened, the left strap 322 and the right strap 323 are exposed from the notches 130 on the corresponding sides. The user can then reach into the second receiving slot II 1122 through the notches 130 to hold the left strap 322 and the right strap 323 and lift the head-mounted device 300 upwards to take it out. The operation is convenient.
[0080] In some embodiments of this application, the notch 130 is a triangular structure, and correspondingly, the fourth protrusion 230 is a triangular plate-shaped structure.
[0081] The recessed portion 121 has a triangular recessed structure, and correspondingly, the second protrusion 210 has a triangular protrusion structure.
[0082] Two fourth protrusions 230 are respectively located on the outside of the second protrusion 210. There is a gap 250 between the second protrusion and the fourth protrusion 230. When the first box 100 and the second box 200 are closed, the gap 250 makes way for the left strap 322 and the right strap 323 located in the second receiving groove II 1122, so as to avoid interference between the second box 200 and the left strap 322 and the right strap 323 during the closing process, which would affect the smooth fastening of the second box 200 and the first box 100.
[0083] In some embodiments of this application, the rotatable connection between the first box body 100 and the second box body 200 is located at the center of one side of the packaging box. When the packaging box is open, the first box body 100 and the second box body 200 lie flat on the same plane, such as... Figure 8 As shown.
[0084] In the flat state, the first box 100 and the second box 200 do not require any other stop structures to keep them in the open state.
[0085] Furthermore, the first box 100 and the second box 200 are laid flat after opening, and the receiving slot 110 is fully exposed, which facilitates the insertion and removal of the head-mounted device 300, so as to better demonstrate the placement of the head-mounted device 300 in the receiving slot 110.
[0086] In some embodiments of this application, the packaging box further includes a fixing part 30, which is used to stop the first box body 100 and the second box body 200 in the closed position.
[0087] In one specific embodiment, reference is made to Figure 2 The fixing part 30 is a sealing sticker 31. At the end away from the rotatable connection between the first box 100 and the second box 200, the sealing sticker 31 is used to stick and fix the first box 100 and the second box 200.
[0088] In another specific embodiment, the fixing part 30 is a protrusion and slot structure provided on the first box 100 and the second box 200, and the stopping is achieved by the snap-fit structure.
[0089] In some embodiments of this application, the packaging box further includes a sleeve 20, which is open at both ends. The first box body 100 and the second box body 200 are placed inside the sleeve 20 after being closed. Figure 1 As shown.
[0090] The following combination Figures 3 to 5 The process of removing the head-mounted device 300 from the packaging box is briefly described as follows:
[0091] First, refer to Figure 3 Remove the closed packaging box body 10 from the sleeve 20;
