[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] See Figure 1 and Figure 2 The present invention provides a protective shell 1, which includes a back plate 10, a frame 20 surrounding the back plate 10 and a bracket 30. The frame 20 and the back plate 10 together form an electronic device housing cavity, which is used to house electronic devices (such as mobile phones, tablet computers, etc.). The bracket 30 is disposed on the back plate 10.

[0042] See Figure 3The back panel 10 includes a support structure 100 and a cover 200. The support structure 100 includes a bracket storage area and a hollow area, which can be any area other than the bracket storage area. The bracket storage area is provided with a bracket receiving groove 110 for placing the bracket 30. The hollow area is provided with multiple hollow structures 101. The cover 200 is located on one side of the support structure 110 and covers the hollow structures 101. The support structure 100 can be a plate-like structure, with multiple hollow structures 101 spaced apart on the largest surface of the support structure 100. The support structure 100 can be made of materials such as PC (Polycarbonate), nylon, silicone, TPU (Thermoplastic Polyurethane), and wood. The cover 200 can be an ultralight composite material part, such as Kevlar sheet, which not only reduces weight and improves aesthetics but also enhances the feel. In this embodiment, such as... Figure 3 and Figure 4 As shown, the hollow structure 101 is cylindrical or honeycomb-shaped. Of course, this embodiment is not limited to this, and the hollow structure 101 can also be other shapes. Furthermore, the spacing between two adjacent hollow structures 101 is 0.5mm to 1.5mm. This setting allows more hollow structures 101 to be formed while the support structure 100 is being formed, thereby minimizing weight while ensuring support and protection.

[0043] The protective case 1 provided in this embodiment sets the back plate 10 as a support structure 100 and a cover 200. The support structure 100 is provided with a bracket storage area and a hollow area. The bracket 30 is set in the bracket receiving groove 110 in the bracket storage area. Multiple hollow structures 101 are provided in the hollow area. By setting the hollow structure 101 outside the bracket connection area, the stable connection of the bracket is ensured and the overall weight of the protective case is reduced. Furthermore, by covering the hollow structure with the cover 200, the aesthetics of the protective case 1 and the user's grip feel are improved, thus enhancing the user experience.

[0044] In one embodiment of this invention, the hollow structure 101 can be, for example, a blind hole. The blind hole is recessed on the outer surface of the support structure 100 near the bracket 30. The cover 200 covers the outer surface of the support structure 100. By providing the cover 200, the hollow structure 101 can be covered, improving aesthetics and grip. At the same time, it can prevent dust and other contaminants from entering the hollow structure 101. The interior space of the hollow structure 101 is relatively small, and dust is difficult to clean once it enters. Therefore, the cover 200 can effectively prevent dirt from getting in. Furthermore, the distance between two adjacent blind holes is 0.5mm to 1.5mm. This arrangement allows for the formation of more hollow structures 101 while the support structure 100 is being formed, thereby minimizing weight while ensuring support and protection.

[0045] In another embodiment of this example, such as Figure 3 As shown, the hollow structure 101 is a through hole that penetrates the support structure 100 along the thickness direction of the back plate 10, allowing the hollow structure 101 to be seen from both sides of the support structure 100. Therefore, two cover members 200 are provided, one on each side of the support structure 100 along the thickness direction of the back plate 10. The cover members 200 cover the hollow structure 101, improving aesthetics and grip. They also prevent dust from entering the hollow structure 101, as the interior space is relatively small and dust is difficult to clean once inside. Therefore, the cover members 200 effectively prevent dirt accumulation. Furthermore, the spacing between adjacent through holes is 0.5mm to 1.5mm. This arrangement allows for the formation of more hollow structures 101 while the support structure 100 is being molded, thus minimizing weight while maintaining support and protection.

[0046] See Figure 3 , Figure 5 , Figure 6 and Figure 7 The specific shape and structure of the back panel 10 can be set according to actual needs. The cover 200 is attached to the support structure 100. Specifically, the cover 200 can be attached to the support structure 100 by adhesive, double-sided tape, liquid adhesive, or hot melt adhesive.

[0047] See also Figure 7The bracket receiving groove 110 has an annular structure, and the hollowed-out area includes a first hollowed-out area 121 and a second hollowed-out area 122. The bracket receiving groove 110 is arranged around the first hollowed-out area 121, that is, the first hollowed-out area 121 is located inside the ring of the bracket receiving groove 110; the second hollowed-out area 122 is arranged around the bracket receiving groove 110, that is, the second hollowed-out area 122 is located outside the ring of the bracket receiving groove. Further, in one embodiment of this embodiment, the first hollowed-out area 121 is provided with a plurality of hollowed-out structures 101 arranged in a row; in another embodiment of this embodiment, the second hollowed-out area 122 is provided with a plurality of hollowed-out structures 101 arranged in a row; in yet another embodiment of this embodiment, the first hollowed-out area 121 is provided with a plurality of hollowed-out structures 101 arranged in a row, and the second hollowed-out area 122 is provided with a plurality of hollowed-out structures 101 arranged in a row. The plurality of hollowed-out structures 101 can be arranged in an array, that is, arranged regularly along the length or width direction of the back plate 10, which is more conducive to production and manufacturing and can effectively control the production and manufacturing costs. In other embodiments, the plurality of hollow structures 101 may also be arranged irregularly.

[0048] Furthermore, the cover 200 includes a first cover 210 and a second cover 220. The first cover 210 and the second cover 220 are disposed on the outer surface of the support structure 100 near the bracket 30. The first cover 210 and the second cover 220 are spaced apart. The first cover 210 covers the first hollow area 121, and the second cover 220 covers the second hollow area 122. That is to say, the cover 200 avoids the bracket receiving groove 110, so that the bracket receiving groove 110 is exposed, which facilitates the installation and storage of the bracket 30.

[0049] In other embodiments of this example, the covering member 200 further includes a third covering member 230. The third covering member 230 is disposed on the inner surface of the supporting structure 100 away from the bracket 30, and covers the first hollow area 121, the bracket receiving area, and the second hollow area 122. Since the bracket receiving groove 110 is disposed on the outer surface of the supporting structure 100, when the third covering member 230 is disposed on the inner surface of the supporting structure 100, it is no longer necessary to consider the problem of the third covering member 230 blocking the bracket receiving groove 110. The third covering member 230 can be set as a whole piece and attached to the inner surface of the supporting structure 100, without the need to cut it into two parts.

[0050] In one embodiment of this example, such as Figure 7As shown, the support structure 100 has a raised rib 120 at the edge of the hollow area. The rib 120 surrounds the hollow area and forms a receiving groove on the surface of the hollow area. The cover 200 covers the receiving groove. Specifically, in one embodiment, the cover 200 is attached to the support structure 100 with double-sided adhesive. Both the cover 200 and the double-sided adhesive are located in the receiving groove. The surface of the cover 200 is flush with the surface of the rib 120, or the surface of the cover 200 is slightly lower than the surface of the rib 120. By having the rib 120 surround the edge of the cover 200, the edge of the cover 200 is less likely to curl up during use. In another embodiment, double-sided adhesive is used to fill the receiving groove, and the cover 200 is adhered to the support structure 100 using the double-sided adhesive. The cover 200 simultaneously covers both the receiving groove and the retaining rib 120, meaning the support structure 100 is completely covered by the cover 200 and not exposed, resulting in a more aesthetically pleasing and uniform overall appearance of the protective shell. The inclusion of the retaining rib 120 and the receiving groove prevents the cover 200 from tearing easily after it is attached to the support structure 100, improving the stability of the attachment.

[0051] See also Figure 9 , Figure 10 and Figure 11 In such Figure 7 and Figure 9 In the illustrated embodiment, the support structure 100 is further provided with a protrusion 140 on the side near the cover 200. The protrusion 140 is disposed within the receiving groove. The periphery of the support structure 100 is surrounded by a protruding rib 120. An adhesive filling groove 150 is formed between the protrusion 140 and the rib 120, and the upper surface of the rib 120 is higher than the upper surface of the protrusion 140. The adhesive filling groove 150 can be formed by the provision of the protruding rib 120 and the protrusion 140. In this embodiment, the height of the protrusion 140 is the height filled by the adhesive material 320, the depth of the adhesive filling groove 150 ranges from 0.15mm to 0.5mm, the thickness of the cover 200 ranges from 0.2mm to 0.6mm, and the height of the rib 120 is the sum of the height of the protrusion 140, the thickness of the double-sided adhesive layer 310, and the thickness of the cover 200, ranging from 0.35mm to 1.1mm, meaning the upper surface of the rib 120 is 0.2mm to 0.6mm higher than the upper surface of the protrusion 140. Preferably, the depth of the adhesive filling groove 150 ranges from 0.15mm, the thickness of the cover 200 ranges from 0.3mm, and the height of the rib 120 is 0.45mm. Of course, this embodiment is not limited to these dimensions.

[0052] See Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 In such Figure 17 In the illustrated embodiment, the surface of the rib 120 is flush with the surface of the protrusion 140, and the cover 200 covers the surfaces of the rib 120 and the protrusion 140. In this embodiment, the cover 200 is directly attached to the support structure 100. The adhesive material 320 in the adhesive filling groove 150 at the edge prevents the cover 200 from tearing easily after it is attached to the support structure 100, thus improving the stability of the attachment. Furthermore, the edge of the cover 200 covers the edge of the support structure 100, so that the edge of the cover 200 is not wrapped by the edge of the support structure 100, further improving the aesthetics and grip comfort of the edge of the cover 200.

[0053] See Figure 2 and Figure 12 The bracket 30 may include a support member 31, a rotating base 32, a mounting member 33, a hinge connector 35, and a rotating shaft 36. It may also include, for example, a magnetic attraction assembly 34. The rotating base 32 can be mounted in the bracket receiving groove 110 via the mounting member 33, and the rotating base 32 can rotate within the bracket receiving groove 110. The support member 31 is rotatably connected to the rotating base 32 via the rotating shaft 36 and the hinge connector 35, thereby enabling the support member 31 to be opened and supported, at which point the support member 31 rotates outside the bracket receiving groove 110. Alternatively, the support member 31 can be closed and housed within the bracket receiving groove 110, and can rotate 360°. The magnetic attraction assembly 34 can be fixed within the rotating base 32 to assist in wireless charging. Of course, this embodiment is not limited to this. In other embodiments, such as... Figure 6 As shown, a mounting hole is also provided on one side of the bracket receiving groove 110. The mounting hole communicates with the bracket receiving groove 110. The bracket is connected to the back plate 10 through a mounting component. The mounting component is installed in the mounting hole, so that the bracket can be opened relative to the back plate 10 to rotate to the outside of the bracket receiving groove 110 for support, or closed and stored in the bracket receiving groove 110.

[0054] In some implementations of this embodiment, see Figure 13The cover member 200 may include a first adhesive area and a second adhesive area. The second adhesive area is located at the edge of the cover member 200 and surrounds the first adhesive area. A double-sided adhesive layer 320 is provided between the first adhesive area and its corresponding hollow area. Hot melt adhesive is provided in the adhesive filling groove 150. The second adhesive area is attached to the adhesive filling groove 150 by the hot melt adhesive. Hot melt adhesive has stronger adhesion than the double-sided adhesive layer 320. In order to ensure a firm bond between the cover member 200 and the support structure member 100, a stronger hot melt adhesive should be used for bonding. However, since the support structure member 100 has a hollow area, if hot melt adhesive is used for bonding, the hot melt adhesive will fill into the hollow area, causing the purpose of setting the hollow area for weight reduction to fail. Therefore, this application achieves the main connection between the cover 200 and the hollow area by setting a double-sided adhesive layer 320. At the same time, an adhesive filling groove 150 is set on the edge of the support structure 100 for setting hot melt adhesive. The edge of the cover 200 and the edge of the support structure 100 are connected by hot melt adhesive. Since the edge is a position that is prone to lifting, the setting of hot melt adhesive can make the adhesion at the edge position more firm.

[0055] Furthermore, in one embodiment of this invention, the second adhesive area covers the protrusion 140, and the edge of the second adhesive area contacts the sidewall of the rib 120. The surface of the second adhesive area is flush with or lower than the surface of the rib 120. By having the rib 120 surround the edge of the cover 200, problems such as edge lifting are less likely to occur at the edge of the cover 200 during use. In another embodiment of this invention, the second adhesive area covers both the protrusion 140 and the rib 120. That is, the support structure 100 is completely covered by the cover 200 and will not be exposed, resulting in a more aesthetically pleasing and uniform overall appearance of the protective shell.

[0056] Furthermore, in some other embodiments of this example, the pasting area can be divided into multiple pasting areas according to the position and shape of the bracket receiving groove 110 and the structure of the supporting structure 100. The corresponding adhesive filling groove 150 is disposed in the edge area of ​​the pasting area, and the number and position of the adhesive filling groove 150 can be set according to the adhesive pasting area 130.

[0057] See also Figure 13In one embodiment of this invention, the support structure 100 is further provided with an injection molding guide structure 160, which does not have any hollow structures 101. In this embodiment, the support structure 100 can be injection molded, for example. The injection molding guide structure 160 improves the fluidity of the injection molding material during the injection molding process, resulting in a more uniform structure. During the injection molding process of the support structure 100, the raw material is typically melted into a liquid state at high temperature and then poured into the mold cavity. The raw material solidifies into a solid state within a short time to form the support structure 100. Because multiple hollow structures 101 need to be injection molded onto the support structure 100, the channels between the hollow structures 101 within the mold cavity become narrow. It is difficult for the liquid raw material to fill all positions in the mold cavity within a short time, resulting in the raw material being unable to reach positions far from the injection port or uneven distribution of the raw material. The injection flow guide structure 160 ensures that there are multiple main channels for the flow of liquid raw materials in the mold cavity. The liquid raw materials first disperse along the main channels to the periphery of the inlet, and then flow into the narrow channels that form each support structure 100 through the main channels. Because the main channels are increased, the flow speed of the liquid raw materials is accelerated. Therefore, in a short time, the liquid raw materials can fill every corner of the mold cavity, ensuring that the injection-molded support structure 100 is intact and the yield is significantly improved.

[0058] Furthermore, the injection molding flow guiding structure 160 may include a first flow guiding portion 161 and a second flow guiding portion 162. The first flow guiding portion 161 is a cross-shaped structure located in the first hollowed-out region 121, and the second flow guiding portion 162 is located in the second hollowed-out region 122. The first flow guiding portion 161 divides the first hollowed-out region 121 into multiple first hollowed-out sub-regions 1211, and the second flow guiding portion 162 divides the second hollowed-out region 122 into multiple second hollowed-out sub-regions 1221. The structure and shape of the injection molding flow guiding structure 160 described above are more conducive to the flow of liquid raw materials within the mold cavity.

[0059] In one embodiment of this invention, the first flow guide 161 is a cross-shaped structure located in the first hollowed-out region 121, dividing the first hollowed-out region 121 into four first hollowed-out sub-regions 1211. The second flow guide 162 is a strip-shaped structure located in the second hollowed-out region 122, extending along the length of the supporting structure 100 to divide the second hollowed-out region 122 into two second hollowed-out sub-regions 1221 located on the left and right sides of the second flow guide 162 along the width direction of the back plate 10. During the injection molding process, the injection molding material can be poured through the center of the cross-shaped structure of the first flow guide 161, guided along the cross-shaped structure, and further guided by the second flow guide 162, thereby forming the first flow guide 161 and the second flow guide 162 without the hollowed-out structure 101.

[0060] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of this utility model.
