Description

Smart blackboard sub-screen and its packaging structure Technical Field

[0001] The present application relates to the technical field of teaching aids, and in particular to a smart blackboard sub-screen and its packaging structure. Background Art

[0002] On a smart blackboard, in addition to the smart interactive main screen, there are often two secondary screens for writing. The main screen can be touched to present teaching content in the form of pictures, videos, etc., while the secondary screen can be used by teachers to write on the blackboard and present teaching content in the form of blackboard writing. In actual classroom application scenarios, the blackboard is often installed directly on the wall of the classroom with no obstructions on all sides. In order to ensure a beautiful appearance and to prevent users (students, teachers, etc.) from reaching into the back of the secondary screen, causing safety accidents such as pulling wires or getting their hands stuck in the back of the secondary screen, a secondary screen baffle needs to be set on the side of the secondary screen.

[0003] As shown in Figure 1, existing auxiliary screen baffles 2' are directly screwed to the back of the auxiliary screen 1'. Due to the high difficulty in positioning during screw locking, to reduce positional deviation after installation, existing auxiliary screen baffles 2' are pre-fixed to the auxiliary screen 1' before shipment. This structure will significantly increase the thickness of the entire auxiliary screen 1' during packaging, requiring thicker packaging materials. Furthermore, the overall volume and thickness of the packaged product are larger, resulting in a smaller number of products that can be loaded during transportation and loading. This in turn leads to problems such as high packaging material consumption and high product transportation costs.

[0004] Summary of the Invention

[0005] The embodiment of the present application provides a smart blackboard sub-screen and its packaging structure, so as to at least solve the technical problems in the related art such as the large thickness of the sub-screen baffle resulting in a large amount of packaging consumables and high transportation costs.

[0006] In the first aspect, an embodiment of the present application provides a smart blackboard sub-screen, including a sub-screen panel and a side baffle for blocking the gap between the sub-screen panel and the wall from the side, the sub-screen panel is provided with a holder, and the side baffle is provided with a clamping structure corresponding to the holder, and the side baffle is fixed to the sub-screen panel by clamping the clamping structure with the holder.

[0007] In the second aspect, an embodiment of the present application provides a packaging structure for a smart blackboard sub-screen, comprising: a packaging body and a sub-screen installed in the packaging body, wherein the sub-screen is the above-mentioned smart blackboard sub-screen; the packaging body has a sub-screen panel mounting portion and a side baffle mounting portion, and the sub-screen panel mounting portion and the side baffle mounting portion are arranged side by side with the direction parallel to the writing surface of the sub-screen panel as a reference; the sub-screen panel is independently fixed in the sub-screen panel mounting portion, and the side baffle is independently fixed in the side baffle mounting portion.

[0008] The present application provides a smart blackboard sub-screen and its packaging structure, in which a card holder is provided on the sub-screen panel, and a corresponding snap-in structure is provided on the side baffle. The card holder is precisely fixed to the sub-screen panel before leaving the factory. The sub-screen panel and the side baffle can be separated for packaging during packaging, thereby effectively reducing the thickness of the packaging material and the overall thickness of the packaged product, thereby achieving the effect of reducing packaging consumables and reducing transportation costs. During on-site installation, the side baffle can be precisely fixed to the sub-screen panel by aligning the snap-in structure on the side baffle with the card holder, ensuring the accuracy of the installation position of the side baffle after installation and ensuring a good appearance after installation. Therefore, this solution achieves the aforementioned effect of reducing packaging consumables and reducing transportation costs without affecting the installation accuracy of the side baffle after installation.

DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0025] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0027] In the description of this application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0028] As shown in Figure 1, existing auxiliary screen baffles 2' are directly screwed to the back of the auxiliary screen 1'. Due to the high difficulty in positioning when screwing, in order to reduce the position deviation of the auxiliary screen baffles 2' after installation, the existing auxiliary screen baffles 2' are all pre-fixed to the auxiliary screen 1' before leaving the factory. This structure will cause the thickness of the entire auxiliary screen 1' to increase significantly during packaging, requiring thicker packaging materials. In addition, the overall volume and thickness of the packaged product are larger, resulting in a smaller number of products that can be loaded during transportation and loading. This in turn leads to problems such as high packaging material consumption and high product transportation costs.

[0029] In order to solve the aforementioned problems, this embodiment provides a smart blackboard sub-screen 100, which aims to provide a new installation structure of the side baffle 2, which can ensure the accuracy of the installation position of the side baffle 2 after on-site assembly. During packaging, the side baffle 2 and the sub-screen panel 1 can be installed independently to reduce the thickness of the overall structure after packaging.

[0030] Specifically, referring to Figure 2-12, the smart blackboard sub-screen 100 of this embodiment includes a sub-screen panel 1 and a side baffle 2 for blocking the gap between the sub-screen panel 1 and the wall from the side. The sub-screen panel 1 is provided with a holder 3, and the side baffle 2 is provided with a clamping structure 23 corresponding to the holder 3. The side baffle 2 is fixed to the sub-screen panel 1 by clamping the clamping structure 23 with the holder 3.

[0031] During the production phase, after the auxiliary screen 1, the holder 3, and the side baffles 2 are individually machined and formed, the holder 3 is accurately installed in the workshop at the designed position on the auxiliary screen 1 using specialized positioning equipment. Since the holder 3 and the clipping structure 23 on the side baffles 2 are matched, as long as the accuracy of the holder 3 on the auxiliary screen 1 is ensured, the accuracy of the subsequent installation of the side baffles 2 can be guaranteed. Therefore, based on the accurate installation of the holder 3, during the on-site assembly phase, the installer only needs to use the clipping structure 23 to clip the side baffles 2 onto the holder 3 to achieve accurate installation of the side baffles 2 on the auxiliary screen 1.

[0032] The auxiliary screen 1 has a writing surface, which is the side facing the user after installation; the back of the auxiliary screen 1 faces the wall; after installation, one side of the auxiliary screen 1 is connected to the smart interactive main screen, and the side baffle 2 is installed on the side of the auxiliary screen 1 away from the smart interactive main screen. In specific implementation, the side baffle 2 can be located inside the back of the auxiliary screen 1, or outside the side edge of the auxiliary screen 1, as long as it can meet the requirements of blocking the gap between the auxiliary screen 1 and the wall. Regarding the installation of the card holder 3, optionally, the card holder 3 can be installed on the back of the auxiliary screen 1, or on the side of the auxiliary screen 1. Generally speaking, in order to avoid affecting the appearance of the writing surface of the auxiliary screen 1, it is not considered to install the card holder 3 on the writing surface of the auxiliary screen 1; in order to obtain the best look and feel, the card holder 3 and the side baffle 2 are both installed inside the back of the auxiliary screen 1, so that the user cannot observe the existence of the two from the front.

[0033] Based on the combination of the card holder 2 and the card connection structure 23, during on-site assembly, no professional tools are required. The side baffle 2 can be accurately installed on the auxiliary screen panel 1 after the two are aligned. Therefore, when packaging, there is no need to install the side baffle 2 on the auxiliary screen panel 1 first. The two can be packaged independently, so the packaging thickness can be reduced to the greatest extent.

[0034] In summary, based on a smart blackboard sub-screen 100 of the present embodiment, a card holder 3 is provided on the sub-screen panel 1, and a corresponding snap-in structure 23 is provided on the side baffle 2. The card holder 3 is precisely fixed to the sub-screen panel 1 before leaving the factory. The sub-screen panel 1 and the side baffle 2 can be separated for packaging during packaging, thereby effectively reducing the thickness of the packaging material and the overall thickness of the packaged product, thereby achieving the effect of reducing packaging consumables and reducing transportation costs. During on-site installation, the side baffle 2 can be precisely fixed to the sub-screen panel 1 by aligning the snap-in structure 23 on the side baffle 2 with the card holder 3, thereby ensuring the accuracy of the installation position of the side baffle 2 after installation and ensuring a good appearance after installation. Therefore, this solution achieves the aforementioned effect of reducing packaging consumables and reducing transportation costs without affecting the installation accuracy of the side baffle 2 after installation.

[0035] In one embodiment, the holder 3 is disposed on the back side of the auxiliary screen 1 .

[0036] The card holder 3 is arranged on the back side of the auxiliary screen panel 1, so that the card holder 3 can be hidden. After installation, the user cannot observe the existence of the card holder 3 from the front, which provides the best visual experience.

[0037] In one embodiment, the clamping direction of the clamping structure 23 and the clamping base 3 is parallel to the writing surface of the auxiliary screen 1 .

[0038] When the snap-fit ​​structure 23 is snapped into engagement with the base 3, the two must undergo relative displacement to complete the snap-fit. The snap-fit ​​direction of the snap-fit ​​structure 23 and the base 3 indicates that when the snap-fit ​​structure 23 is in the separated state, the snap-fit ​​structure 23 can be moved relative to the base 3 along this snap-fit ​​direction to engage the two. In this solution, the snap-fit ​​direction of the snap-fit ​​structure 23 and the base 3 is parallel to the writing surface of the auxiliary screen 1. During on-site installation, the auxiliary screen 1 can be first fixed to the wall, and then the side panel 2 can be pushed into the back side of the auxiliary screen 1 to achieve the snap-fit ​​connection between the snap-fit ​​structure 23 and the base 3, completing the installation of the side panel 2. Among them, taking the state of the auxiliary screen panel 1 after vertical installation as a reference, when installing the side baffle 2, no matter it is pushed into the back side of the auxiliary screen panel 1 horizontally from the side, or pushed into the back side of the auxiliary screen panel 1 from the top downward, or pushed into the back side of the auxiliary screen panel 1 from the bottom upward, the side baffle 2 is pushed in a direction parallel to the writing surface of the auxiliary screen panel 1, that is, the aforementioned various forms can be applied to the embodiment scheme.

[0039] To further explain the improved advantages of this solution, referring to Figure 1, in the existing blackboard sub-screen structure, screws are used to fix the sub-screen baffle 2' to the sub-screen 1'. Since the screws are detachable, the sub-screen baffle 2' and the sub-screen 1' can be packaged separately when packaging without considering the accuracy of the on-site installation position of the sub-screen baffle 2', and the same thinning packaging effect as this solution can be achieved. However, during on-site assembly, since tools (such as a screwdriver) are required to use screws to fix the sub-screen baffle 2' to the sub-screen 1', the sub-screen baffle 2' can only be assembled with the sub-screen 1' first, and then the combined structure can be installed on the wall as a whole. When mounting on the wall, due to the obstruction of the secondary screen baffle 2', it will be difficult for the staff to see the docking situation between the hanging structure on the back of the secondary screen 1' and the hook on the wall, which increases the difficulty of installing the secondary screen 1'; in addition, when assembling the secondary screen baffle 2' and the secondary screen 1', the secondary screen 1' needs to be placed flat on the ground, and then the secondary screen baffle 2' is installed from top to bottom. Therefore, the process requires a large enough space on site to provide a flat platform for the secondary screen 1', and the installation site requirements are relatively high.

[0040] In this solution, however, no tools are required to install the side panels 2, and the movement direction of the side panels 2 during installation is parallel to the writing surface of the auxiliary screen 1. Therefore, the width of the gap between the auxiliary screen 1 and the wall is sufficient to accommodate the side panels 2. Therefore, this solution allows the auxiliary screen 1 to be mounted on the wall first, followed by the side panels 2, thereby reducing the installation difficulty of the auxiliary screen 1 and side panels 2. Furthermore, since the auxiliary screen 1 does not need to be placed flat on the ground, the installation space requirements are relatively low.

[0041] In one embodiment, in combination with Figures 5-9, the card seat 3 has a first card block 31 and a second card block 32, and the card structure 23 includes a first card portion 231 and a second card portion 232, the first card portion 231 abuts against the side of the first card block 31 close to the auxiliary screen panel 1, and the second card portion 232 abuts against the side of the second card block 32 away from the auxiliary screen panel 1, thereby limiting the side baffle 2 from moving relative to the auxiliary screen panel 1 in a direction perpendicular to the writing surface of the auxiliary screen panel 1.

[0042] That is, the first clamping block 31 and the second clamping block 32 constitute staggered limit blocks, with the writing surface of the auxiliary screen 1 as the front and the back as the back. The first clamping block 31 can limit the rearward movement of the side baffle 2, and the second clamping block 32 can limit the forward movement of the side baffle 2, thereby limiting the displacement of the side baffle 2 in the front-to-back direction. In this solution, the first clamping portion 231 and the second clamping portion 232 move simultaneously in a direction parallel to the writing surface of the auxiliary screen 1, so that they can enter the front side of the first clamping block 31 and the back side of the second clamping block 32 respectively. Therefore, this structure can meet the installation requirements of the design of this embodiment. That is, during installation, the clamping direction of the clamping structure 23 and the base 3 is parallel to the writing surface of the auxiliary screen 1.

[0043] As shown in Figure 5, in order to facilitate the first clamping portion 231 and the second clamping portion 232 to form a limit with the first clamping block 31 and the second clamping block 32 respectively, the first clamping portion 231 and the second clamping portion 232 are staggered. Specifically, the second clamping portion 232 is arranged backward relative to the first clamping portion 231, so that the first clamping portion 231 can abut the front side of the first clamping block 31, and the second clamping portion 232 can abut the rear side of the second clamping block 32.

[0044] In order to enable the first clamping portion 231 to abut against the front side of the first clamping block 31, a certain distance must be maintained between the first clamping block 31 and the auxiliary screen panel 1, so that a plug-in slot allowing the first clamping portion 231 to be inserted is formed between the first clamping block 31 and the auxiliary screen panel 1. In order to facilitate insertion and ensure reliability after plugging, the first clamping portion 231 and the plug-in slot are clearance-matched. Preferably, the clearance between the first clamping portion 231 and the plug-in slot is 0.2~0.3mm.

[0045] In one embodiment, the holder 3 is provided with an anti-slip portion, which is used to cooperate with the clamping structure 23 to limit the horizontal movement of the side baffle 2 relative to the auxiliary screen 1 in a direction parallel to the writing surface of the auxiliary screen 1.

[0046] An anti-slip portion is provided on the card seat 3 to cooperate with the clamping structure 23 to limit the horizontal movement of the side baffle 2 relative to the auxiliary screen 1 in a direction parallel to the writing surface of the auxiliary screen 1. That is, based on the angle shown in Figure 2, the anti-slip portion limits the displacement of the side baffle 2 in the left and right directions, thereby ensuring the stability of the side baffle 2 in the left and right directions after installation.

[0047] Regarding the setting of the anti-slip part, in one embodiment, in combination with Figures 3 and 5, the anti-slip part includes the first clamping block 31 and the barb 34 provided on the second clamping block 32; the side baffle 2 includes a baffle body 21 perpendicular to the writing surface of the auxiliary screen 1, and the clamping structure 23 is vertically connected to the side of the baffle body 21 close to the center of the auxiliary screen 1; the first clamping block 31 abuts the baffle body 21, and the second clamping part 232 maintains a gap with the baffle body 21, so that the side of the second clamping part 232 close to the baffle body 21 can abut the barb 34, thereby realizing the limiting function of the anti-slip part.

[0048] Specifically, taking the angle shown in Figure 2 as an example, the left side of the first engaging block 31 abuts the baffle body 21, thereby restricting rightward movement of the side baffle 2; the right side of the barb 34 abuts the second engaging portion 232, thereby restricting leftward movement of the side baffle 2. Thus, this structure achieves the required anti-slip function of the anti-slip portion of this embodiment. Furthermore, this structure utilizes the first engaging block 31 and the barb 34 added to the second engaging block 32, achieving this goal with the simplest structure. To achieve installation, when the second clamping portion 232 moves in a direction parallel to the writing surface of the auxiliary screen 1, the second clamping portion 232 can pass over the hook 34 and enter the right side of the hook 34. The left side of the hook 34 is provided with an inclined guide surface. During installation, based on the guide surface, the second clamping portion 232 can squeeze the second clamping block 32 to gradually deform in the direction close to the auxiliary screen 1 until the second clamping portion 232 passes over the hook 34. The second clamping block 32 returns to its original shape, allowing the second clamping portion 232 to abut against the right side of the hook 34. Therefore, the anti-slip structure of this solution can also meet the installation requirements of the design of this embodiment.

[0049] In order to adapt to the precision error and assembly error of workpiece processing, make the side baffle 2 easy to install, and ensure that the side baffle has high stability after installation, the fitting clearance between the hook 34 and the second clamping part 232 is controlled at 0.2~0.3mm; the fitting clearance between the first clamping block 31 and the baffle body 21 is controlled at 0.3~0.4mm.

[0050] In one embodiment, the card seat 3 also includes a fixing seat 35, and the fixing seat 35 is fixed on the auxiliary screen panel 1; two first card blocks 31 and one second card block 32 are provided on the side of the fixing seat 35 close to the baffle body 21, and the first card blocks 31 and the second card blocks 32 are arranged alternately.

[0051] Referring to Figures 8-9 , the fixing base 35 is used to abut against the auxiliary screen panel 1, thereby securing the clamping base 3 to the auxiliary screen panel 1. Optionally, the fixing base 35 is secured to the auxiliary screen panel 1 using screws or rivets. A first clamping block 31, a second clamping block 32, and a first clamping block 31 are arranged in order from top to bottom on the side of the fixing base 35 near the baffle body 21, forming a labyrinthine clamping structure for the side baffle 2. This structure offers the advantage of positional stability.

[0052] In one embodiment, an avoidance groove is formed between the second clamping block 32 and the auxiliary screen panel 1. Based on the avoidance groove, the second clamping portion 232 can squeeze the second clamping block 32 to deform, so that the second clamping portion 232 can pass over the barb 34 and engage with the barb 34.

[0053] In conjunction with Figures 3 and 9, in order to enable the second clamping portion 232 to pass over the hook 34 and be clamped with the hook 34, an avoidance groove is formed between the second clamping block 32 and the auxiliary screen panel 1, that is, a moving distance is maintained between the second clamping block 32 and the auxiliary screen panel 1, so that during installation, the second clamping portion 232 can squeeze the second clamping block 32 to deform toward the side where the auxiliary screen panel 1 is located, and the second clamping portion 232 can pass through the hook 34 from the side of the hook 34 facing away from the auxiliary screen panel 1, thereby meeting the design and installation requirements of this embodiment.

[0054] In one embodiment, referring to Figures 2-3, a horizontally arranged guard plate 22 is respectively connected to the upper and lower sides of the baffle body 21, and the facing sides of the two guard plates 22 are respectively in contact with the base 3 to limit the vertical displacement of the side baffle 2.

[0055] That is, at least two retainers 3 must be positioned above and below the secondary screen 1. The uppermost retainer 3 abuts the underside of the top guard plate 22, while the lowermost retainer 3 abuts the upper side of the bottom guard plate 22, thereby limiting the vertical displacement of the side guard plate 2. Combined with the previously described approach of limiting the forward and backward movement and left and right movement of the side guard plate 2, this embodiment can completely secure the side guard plate 2. Using the perspective of Figure 2 as an example, the side guard plate 2 can be installed from left to right, thus meeting the design and installation requirements of this embodiment.

[0056] In one embodiment, referring to Figure 5, the base 3 also includes a third clamping block 33, and the clamping structure 23 also includes a third clamping portion 233. The two opposing sides of the guard plates 22 are respectively provided with a third clamping portion 233, and the third clamping portion 233 abuts against the side of the third clamping block 33 close to the auxiliary screen panel 1 to limit the side baffle 2 from moving away from the auxiliary screen panel 1 in a direction perpendicular to the writing surface of the auxiliary screen panel 1 relative to the auxiliary screen panel 1.

[0057] On the basis of the engagement between the first clamping portion 231 and the first clamping block 31, the structure of the guard plate 22 is utilized here to set a third clamping portion 233 perpendicular to the first clamping portion 231. The third clamping block 33 is provided to clamp the third clamping portion 233, which can increase the limiting area of ​​the side baffle 2, thereby further improving the stability of the installation of the side baffle 2.

[0058] In one embodiment, at least two of the holders 3 arranged in a vertical direction are provided on the auxiliary screen 1 .

[0059] At least two retaining brackets 3 are provided to fix the upper and lower ends of the side baffle 2, respectively, to fully limit the position of the side baffle 2. Preferably, a retaining bracket 3 is also provided in the middle of the side baffle 2 for clamping. In other embodiments, four, five, or other numbers of retaining brackets 3 may be provided on a secondary screen panel 1.

[0060] In one embodiment, referring to Figures 2-3, the upper and lower ends of the side baffle 2 are respectively connected to a wall connecting frame 4. After installing the side baffle 2, the wall connecting frame 4 is fixed to the wall using screws or rivets. The wall connecting frame 4 and the side baffle 2 can provide support for the auxiliary screen panel 1, thereby improving the stability of the installation of the auxiliary screen back panel 1.

[0061] On the other hand, referring to Figures 10-12, this embodiment also provides a packaging structure of a smart blackboard sub-screen, including: a packaging body 200 and a sub-screen installed in the packaging body 200, and the sub-screen is the above-mentioned smart blackboard sub-screen 100; the packaging body 200 has a sub-screen panel mounting part 201 and a side baffle mounting part 202, and the sub-screen panel mounting part 201 and the side baffle mounting part 202 are arranged side by side with the direction parallel to the writing surface of the sub-screen panel 1 as the reference; the sub-screen panel 1 is independently fixed in the sub-screen panel mounting part 201, and the side baffle 2 is independently fixed in the side baffle mounting part 202.

[0062] That is, this solution is based on the characteristic that the auxiliary screen panel 1 and the side panel 2 can be separated during packaging. The side panel 2 is packaged side by side on the side of the auxiliary screen panel 1 with the direction parallel to the writing surface of the auxiliary screen panel 1 as the basis, so that the overall thickness after packaging is greatly reduced, thereby achieving the effect of reducing packaging materials and reducing transportation costs.

[0063] It's important to note that since a smart blackboard typically consists of a main smart interactive screen and two secondary screens on either side, two secondary screens are typically packaged in one package. Referring to Figure 1 , in a traditional solution, the writing surfaces of the two secondary screens 1' are mounted facing each other, with the secondary screen baffles 2' on the two secondary screens 1' facing away from each other. Therefore, the thickness of the entire packaged structure after packaging is: the thickness of the two secondary screens 1' + the width of the two secondary screen baffles 2' + the excess thickness of the packaging material.

[0064] In this solution, as shown in Figures 10-11 , the two auxiliary panels 1 can be stacked vertically, and the two side panels 2 can be stacked horizontally. This allows the thickness of the entire packaging structure to be calculated as follows: the thickness of the two auxiliary panels 1 + the excess thickness of the packaging material; or alternatively, the width of one side panel 2 + the excess thickness of the packaging material. Clearly, the packaging structure of this solution is thinner than that of conventional solutions.

[0065] In one embodiment, referring to Figure 11, the packaging body 200 includes a packaging shell 5, a first embedded block 6 and a second embedded block 7. A first mounting position 53 corresponding to the auxiliary screen panel mounting portion 201 and a second mounting position 54 corresponding to the side baffle mounting portion 202 are formed in the packaging shell 5. The first embedded block 6 clamps and fixes the auxiliary screen panel 1 in the first mounting position 53; the second embedded block 7 clamps and fixes the side baffle 2 in the second mounting position 54.

[0066] The first and second inner blocks 6 and 7 are respectively provided to securely fasten the auxiliary screen 1 and side panels 2, providing support and protection for the auxiliary screen 1 and side panels 2, and improving their stability. Specifically, the first and second inner blocks 6 and 7 are each provided with a groove corresponding to the secured areas on the auxiliary screen 1 or side panels 2. The first and second inner blocks 6 and 7 are preferably made of a cushioning material such as foam, sponge, or plastic foam.

[0067] In one embodiment, the packaging shell 5 includes a bottom shell 51 and an upper cover 52. During packaging, the first embedded block 6, the second embedded block 7, the auxiliary screen panel 1 and the side baffle 2 are first installed in the bottom shell 51, and then the upper cover 52 is closed to achieve comprehensive packaging of the auxiliary screen panel 1 and the side baffle 2.
