Description

Technical Field

[0001] The utility model relates to the technical field of light guide plates, in particular to a protective structure for preventing light guide plates from being damaged by incoming materials. Background Art

[0002] The light guide plate is constructed from optical-grade acrylic / PC sheet material. Light guide points are printed on the underside of the optical-grade acrylic sheet using laser engraving, V-shaped cross-grid engraving, and UV screen printing, using a high-tech material with an extremely high refractive index and no light absorption. The optical-grade acrylic sheet absorbs the light emitted from the lamp and its retention on the surface. When light strikes each light guide point, the reflected light diffuses in all directions, breaking the reflection conditions and exiting through the front of the light guide plate.

[0003] Existing incoming light guide plates are protected by covering the upper and lower surfaces (light-emitting surface and mesh surface) with protective film. However, the light guide plates are stacked and stored together during shipment and use. Since the light guide plates themselves are not resistant to bumps and other damage, the protective film alone cannot completely prevent the defects caused by bumps and damages between the light guide plates after being folded up and down. Therefore, a protective structure is proposed to prevent incoming light guide plates from being damaged. Utility Model Content

[0004] Based on this, it is necessary to provide a protective structure to prevent the light guide plates from being damaged by incoming materials in order to address the above technical problems. Anti-collision foam pads are added to the protective film to separate the upper and lower adjacent light guide plates to reduce the defects caused by collisions between the light guide plates.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A protective structure for preventing light guide plates from being damaged by incoming materials, comprising:

[0007] A light guide plate having a light emitting surface and a dot surface at the top and bottom of the light guide plate respectively;

[0008] A protective film body, comprising an upper protective film and a lower protective film, wherein the upper protective film and the lower protective film are respectively distributed on the light emitting surface and the mesh surface for covering and protecting the light guide plate;

[0009] Anti-collision foam pads are distributed on the protective film body, and when a plurality of light guide plates are stacked, they can be prevented from colliding with each other due to the action of the anti-collision foam pads.

[0010] Furthermore, the anti-collision foam pad is distributed on the surface of the upper protective film.

[0011] Furthermore, the anti-collision foam pad includes an outer foam pad and an inner foam pad;

[0012] The outer foam pad is distributed at the edge of the upper protective film, and the inner foam pad is arranged at the center of the upper protective film.

[0013] Furthermore, there are four outer foam pads, which are distributed at the four corners of the surface of the upper protective film in a rectangular array.

[0014] Furthermore, an auxiliary foam pad is provided on the surface of the lower protective film;

[0015] The auxiliary foam pad has the same thickness as the anti-collision foam pad.

[0016] Furthermore, the auxiliary foam pads have four;

[0017] The four auxiliary foam pads are correspondingly arranged on the inner side of the upper outer foam pad on the surface of the lower protective film.

[0018] Furthermore, the auxiliary foam pad has a positioning portion extending outward, and a positioning groove adapted to the positioning portion is formed on one side of the outer foam pad;

[0019] After the plurality of light guide plates are stacked, the adjacent anti-collision foam pads and outer foam pads will form a snap-fit ​​assembly.

[0020] Furthermore, a gap is left between the outer side of the positioning portion and the positioning groove.

[0021] Furthermore, outer sides of the upper protective film and the lower protective film are both provided with extension films extending outwards at the edge of the light guide plate.

[0022] Furthermore, the width of the stretch film is between five millimeters and fifteen millimeters.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The utility model provides a protective structure for preventing light guide plates from being damaged by incoming materials. By adding an anti-collision foam pad on the traditional upper protective film, when multiple light guide plates are folded in sequence along the height direction, adjacent light guide plates can be fairly separated by the anti-collision foam pad, thereby avoiding the situation where adjacent light guide plates clash with each other and are easily damaged.

[0025] At the same time, due to the separation of anti-collision foam pads, there is also a certain height gap between adjacent light guide plates, which makes it more convenient to take out and use the stacked duct plates in an orderly manner;

[0026] By arranging an auxiliary foam pad on the lower protective film, the anti-collision foam pad can form a support together with the auxiliary foam pad after the adjacent light guide plates are stacked, thereby increasing the support area and improving the support strength. At the same time, the positioning portion and the positioning groove can be matched to ensure that the edges of the multiple light guide plates are aligned after stacking. At the same time, it also forms a positioning effect for the light guide plates to a certain extent, making it difficult for them to slide against each other, thereby ensuring the overall stability after folding.

[0027] By extending the upper and lower protective films outward and designing the dimensions to cover the edges of the light guide plate, effective coverage protection can be provided for the edges of the light guide plate during the actual stacking process, further improving the overall protection effect of the light guide plate.

[0041] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0042] As described in the background technology, the existing light guide plate materials are protected by covering the upper and lower surfaces (light-emitting surface and mesh surface) with protective film, and the light guide plates are stacked up and stored in a concentrated manner during shipment and use. Since the light guide plates themselves are not resistant to bumps and other damage, the protective film alone cannot completely avoid the defects caused by bumps and damages between the light guide plates after folding up and down.

[0043] In order to solve this technical problem, the utility model provides a protective structure for preventing incoming light guide plates from being damaged, which is applied to light guide plates.

[0044] Specifically, please refer to Figures 1-8 The protective structure for preventing the light guide plate from being damaged by incoming materials specifically includes:

[0045] A light guide plate 1 having a light emitting surface 11 and a dot surface 12 at the top and bottom of the light guide plate 1 respectively;

[0046] The protective film body 2 includes an upper protective film 21 and a lower protective film 22 , wherein the upper protective film 21 and the lower protective film 22 are respectively distributed on the light emitting surface 11 and the mesh surface 12 for covering and protecting the light guide plate 1 ;

[0047] Anti-collision foam pads 3 are distributed on the protective film body 2 , and when a plurality of light guide plates 1 are stacked, they can be prevented from collision with each other due to the anti-collision foam pads 3 .

[0048] The utility model provides a protective structure for preventing light guide plates from being damaged by incoming materials. By adding anti-collision foam pads on the upper protective film of the rotating drum, adjacent light guide plates can be fairly separated by the anti-collision foam pads during the process of folding the multiple light guide plates in sequence along the height direction, thus avoiding the situation where adjacent light guide plates clash with each other and are easily damaged.

[0049] At the same time, due to the separation of the anti-collision foam pads, there is a certain height gap between adjacent light guide plates, which makes it more convenient to take out and use the stacked duct plates in an orderly manner.

[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0053] Please refer to Figures 1-4 As shown, a protective structure for preventing incoming light guide plates from being damaged by collisions comprises a light guide plate 1 having a light emitting surface 11 and a mesh surface 12 at the top and bottom of the light guide plate 1, respectively; a protective film body 2 comprising an upper protective film 21 and a lower protective film 22, the upper protective film 21 and the lower protective film 22 being respectively distributed on the light emitting surface 11 and the mesh surface 12 for covering and protecting the light guide plate 1;

[0054] Anti-collision foam pads 3, which are distributed on the protective film body 2, and can prevent mutual collisions between the plurality of light guide plates 1 when they are stacked. The anti-collision foam pads 3 are distributed on the surface of the upper protective film 21;

[0055] like Figure 4 As shown, the anti-collision foam pad 3 includes an outer foam pad 31 and an inner foam pad 32, wherein the outer foam pad 31 is distributed at the edge of the upper protective film 21, and the inner foam pad 32 is provided at the center of the upper protective film 21;

[0056] There are four outer foam pads 31, and the four outer foam pads 31 are distributed in a rectangular array at the four corners of the surface of the upper protective film 21;

[0057] Through the above structural design, after the light guide plates 1 with the anti-collision foam pads 3 are stacked, the following Figure 4In the stacked state shown, due to the support of the anti-collision foam pads 3, there is a certain height gap between the upper and lower adjacent light guide plates 1 on their opposite sides. The gap prevents the adjacent light guide plates 1 from contacting each other and causing bumps. At the same time, the gap formed by the anti-collision foam pads 3 facilitates the subsequent removal of the light guide plates 1. The operator can use the fingers to apply force at the gap to separate the light guide plates 1. Compared with the traditional structural design in which the light guide plates 1 are stacked closely together, this facilitates the removal in actual application.

[0058] In this embodiment, the number of inner and outer foam pads 31 is four, and the number of inner foam pad 32 is one. In actual application, the number and position of the outer foam pads 31 and the inner foam pads 32 can be adaptively arranged according to the overall size and weight of different light guide plates 1. For example, by increasing the number of outer foam pads 31 and inner foam pads 32, the overall support effect of the light guide plate 1 can be improved, ensuring that the gap between the upper and lower light guide plates 1 after stacking will not be excessively reduced. This method is suitable for use when the light guide plate 1 is large in size and heavy in weight.

[0059] The protective structure for preventing the light guide plate from being damaged by incoming materials provided in Example 1 is further optimized. Specifically, Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, an auxiliary foam pad 4 is provided on the surface of the lower protective film 22 , and the auxiliary foam pad 4 has the same thickness as the anti-collision foam pad 3 ;

[0060] The auxiliary foam pads 4 have four;

[0061] The four auxiliary foam pads 4 are arranged on the surface of the lower protective film 22 corresponding to the inner side of the upper outer foam pad 31;

[0062] By arranging the structure of the auxiliary foam pad 4 on the lower protective film 22 , during the stacking process between multiple light guide plates 1 , the supporting strength between adjacent light guide plates 1 can be improved through the combined action of the auxiliary foam pad 4 and the outer foam pad 31 .

[0063] The auxiliary foam pad 4 has a positioning portion 41 extending outward, and a positioning groove 42 adapted to the positioning portion 41 is formed on one side of the outer foam pad 31;

[0064] After the plurality of light guide plates 1 are stacked, the adjacent anti-collision foam pads 3 and the outer foam pads 31 will form a snap-fit ​​assembly;

[0065] like Figure 7As shown, after multiple light guide plates 1 are stacked, the auxiliary foam pad 4 on the lower protective film 22 on the upper light guide plate 1 will engage with the positioning groove 42 in the outer foam pad 31 on the upper protective film 21 on the lower light guide plate 1 through the positioning portion 41 to form a snap action;

[0066] The corresponding assembly of the positioning portions 41 and the positioning grooves 42 ensures the placement accuracy of the upper and lower light guide plates 1, thereby ensuring the overall placement accuracy of the multiple layers of light guide plates 1 during folding. At the same time, the corresponding fit of the multiple positioning grooves 42 and the positioning portions 41 forms an axial resistance limit between the two light guide plates 1, preventing relative sliding after placement, thereby further improving the stability of the stacked light guide plates 1.

[0067] As a further optimization of this embodiment: a gap 43 is left between the outer side of the positioning portion 41 and the positioning groove 42. Through the effect of the gap 43, the positioning portion 41 can be easily inserted into the corresponding positioning groove 42 during the stacking of the upper and lower light guide plates 1. Similarly, in the subsequent removal and use process, it is more convenient to remove the light guide plate 1 and its upper positioning portion 41 from the positioning groove 42 on the lower light guide plate 1, avoiding the formation of interference fit and affecting stacking and taking.

[0068] The protective structure for preventing the light guide plate from being damaged by incoming materials provided in embodiment 1 or 2 is further optimized, such as Figure 3 As shown, the outer sides of the upper protective film 21 and the lower protective film 22 are both extended outwards at the edge of the light guide plate 1 to have an extension film 23;

[0069] The extended film 23 can protect the main body of the light guide plate 1 while the upper protective film 21 and the lower protective film 22 protect the light guide plate 1. The extended film 23 extending to the outside can also protect the edge of the light guide plate 1, thereby further improving the protection effect of the light guide plate 1.

[0070] As a further optimization of this embodiment: the width of the stretching film 23 is between five millimeters and fifteen millimeters.

[0071] The use process of the protective structure provided by the present invention for preventing light guide plates from being damaged by incoming materials is as follows: an anti-collision foam pad 3 is designed on the upper protective film 21, and then an auxiliary foam pad 4 is arranged on the lower protective film 22 according to the position of the outward foam pad 31, and then a positioning groove 42 is opened on the outer foam pad 31 to match the positioning part 41 on the auxiliary foam pad 4, and the size of the positioning groove 42 is slightly larger than the outer diameter of the positioning part 41, and then when multiple light guide plates 1 are stacked and stacked in order, the auxiliary foam pad 4 on the upper light guide plate 1 will be engaged with the positioning groove 42 on the outer foam pad 31 on the corresponding light guide plate 1 below through the positioning part 41 thereon, and the above steps are repeated in sequence to finally complete the stacking of multiple light guide plates 1 and the collision protection during the stacking process.
