[0003] In related technologies, in order to improve the ease of assembling and disassembling protective cases with electronic products, the lower side panel of the protective case is usually cut to make the lower side panel intermittent, so as to reduce the hardness of the protective case. However, this will result in the side panel of the protective case being incomplete, the protection will be weaker, and the edges of the intermittent side panel are very easy to scratch the user's hands, resulting in a poor user experience. Utility Model Content

[0004] To address the aforementioned technical problems, this application proposes a protective case and a mobile phone case to enhance the protective effect of the protective case, improve the ease of installation and removal, and mitigate the problem of scratches to the user's hands caused by the clearance groove.

[0005] This application provides a protective shell, which includes: a back plate and a frame formed by bending and extending the edge of the back plate to one side, the frame including at least an upper side plate and a lower side plate; wherein, an avoidance groove is provided on the end face of the upper side plate away from the back plate, extending toward the back plate and penetrating from the inner surface of the upper side plate or the lower side plate to the outer surface; the depth of the avoidance groove is less than the dimension of the upper side plate or the lower side plate with the avoidance groove along the depth direction of the avoidance groove.

[0006] This application proposes a mobile phone case, which includes: a rectangular back panel and a frame formed by bending and extending the edge of the back panel to one side. The frame includes an upper side panel, a left side panel, a lower side panel, and a right side panel connected end to end. The lower side panel has a charging port clearance groove and at least one speaker hole clearance hole. The distance between the charging port clearance groove and the back panel is in the range of 0.2mm to 1mm. The corner of the charging port clearance groove is provided with a second rounded corner structure, and the radius of the second rounded corner structure is in the range of 2mm to 3mm.

[0007] The beneficial effect of this application's technical solution is that the protective shell provided includes a back plate and a frame formed by bending and extending the edge of the back plate to one side. The frame includes at least an upper side plate and a lower side plate. The upper or lower side plate has a clearance groove extending towards the back plate and penetrating from its inner surface to its outer surface on one end face away from the back plate. The depth of the clearance groove is less than the dimension of the upper or lower side plate along the depth direction of the clearance groove. In this way, the depth of the clearance groove is less than the dimension of the upper or lower side plate along the depth direction, and the clearance groove is opened from the end face of the upper or lower side plate away from the back plate, ensuring that the clearance groove does not penetrate the upper or lower side plate along the depth direction. On the one hand, the part of the upper or lower side panel that is not through can increase the protective effect of the protective case and the ability to fix the phone; on the other hand, the setting of the clearance groove can improve the convenience of the protective case's installation and removal; furthermore, the clearance groove does not penetrate the upper or lower side panel along the depth direction, so that the upper or lower side panel is not interrupted, which can improve the problem of the clearance groove scratching the user's hand, thereby improving the user experience.

[0021] Protective cases are common accessories for electronic products, serving to protect them. Currently, protective cases on the market are mainly divided into two categories: one is made of flexible materials, such as the common TPU soft case; the other is made of rigid materials or is entirely rigid, such as cases made of hard resin, aramid, etc. Flexible protective cases have the advantage of good impact resistance, but the disadvantage is that they are too thick, affecting the feel of the electronic product. Rigid protective cases, while having weaker impact resistance, can be made much thinner and lighter.

[0022] Protective cases made of synthetic fiber materials, such as aramid, carbon fiber, and glass fiber, are becoming a high-tech trend. These materials are lightweight, thin, impact-resistant, and wear-resistant, but their rigidity makes them difficult to disassemble and install. To address this, the side panels of the protective case are cut, creating discontinuous sections to reduce rigidity. However, this results in incomplete side panels and weakened protection. Furthermore, the edges of these discontinuous sections can easily scratch the user's hands, leading to a poor user experience.

[0023] Therefore, this application proposes a protective case that can be used on mobile phones, tablets, cameras, and other portable electronic products, providing enhanced protection for these devices. The embodiments of this application will be described using a mobile phone as an example, and the protective case will also be described using a mobile phone protective case as an example.

[0024] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the protective shell 10 of this embodiment includes a back plate 1 and a frame 2 formed by bending and extending the edge of the back plate 1 to one side. The frame 2 includes at least an upper side plate 21 and a lower side plate 23. The upper side plate 21 or the lower side plate 23 is provided with a relief groove 2111 extending toward the back plate 1 and penetrating from the inner surface of the upper side plate 21 or the lower side plate 23 to the outer surface. The depth of the relief groove 2111 is less than the dimension of the upper side plate 21 with the relief groove 2111 along the depth direction z of the relief groove 2111.

[0025] The frame 2 and the back panel 1 form a cavity for housing the electronic product, and the cavity has an opening on the side facing away from the back panel 1. When the opening faces the user, the side panel of the protective shell 10 facing away from the user is the back panel 1, the side panel above the cavity is the upper side panel 21, and the side panel below the cavity is the lower side panel 23. After the protective shell 10 is assembled with the electronic product, when the electronic product is in the default display state, the upper side panel 21 is positioned corresponding to the top of the electronic product, and the lower side panel 23 is positioned corresponding to the bottom of the electronic product.

[0026] The aforementioned clearance groove refers to a slot with a accommodating space. During the use of the protective shell 10, the clearance groove can be used to accommodate other objects or accessories, such as an operator's hand or a charging port for electronic products, or it can be used to accommodate other objects.

[0027] The inner surface of the upper side panel 21 refers to the side of the protective shell 10 facing the electronic product when the electronic product is mounted thereon, where the outer surface of the upper side panel 21 is set opposite to the inner surface; the inner surface of the lower side panel 23 refers to the side of the protective shell 10 facing the electronic product when the electronic product is mounted thereon, where the outer surface of the lower side panel 23 is set opposite to the inner surface.

[0028] In this embodiment, the depth of the clearance groove 2111 is less than the dimension of the upper side plate 21 or lower side plate 23 along the depth direction z, and the clearance groove 2111 is opened from the end face of the upper side plate 21 or lower side plate 23 away from the back plate 1, so that the clearance groove 2111 does not penetrate the upper side plate 21 or lower side plate 23 along the depth direction z. On the one hand, the part of the upper side plate 21 or lower side plate 23 that does not penetrate can increase the protective effect of the protective case 10 and the ability to fix the mobile phone; on the other hand, the setting of the clearance groove 2111 can improve the convenience of disassembling and assembling the protective case 10; and furthermore, the clearance groove 2111 does not penetrate the upper side plate 21 or lower side plate 23 along the depth direction z, so that the upper side plate 21 or lower side plate 23 is uninterrupted, which can improve the problem of the clearance groove 2111 scratching the user's hand, thereby improving the user experience.

[0029] In some embodiments, the frame 2 includes a left side panel 22 and a right side panel 24, with the upper side panel 21, left side panel 22, lower side panel 23 and right side panel 24 connected end to end to form the frame 2.

[0030] After the protective case 10 is assembled with the electronic product, when the electronic product is in the default display state, and the opening is defined to face the user, the side panel of the protective case 10 located on the user's right side is the right side panel 24, and the side panel located on the user's left side is the left side panel 22.

[0031] In some application scenarios, the upper side panel 21 and the lower side panel 23 are arranged opposite each other, and the left side panel 23 and the right side panel 24 are arranged opposite each other. The depth direction z of the upper side panel 21, the left side panel 22, the lower side panel 23 and the right side panel 24 are consistent to match the electronic device.

[0032] In other application scenarios, the structure of border 2 can be adjusted based on the shape of the phone.

[0033] In some embodiments, the clearance groove 2111 includes a first clearance groove 211 and a second clearance groove 230; the upper side plate 21 has a first clearance groove 211 extending toward the back plate 1 and penetrating from the inner surface of the upper side plate 21 to the outer surface on one end face away from the back plate 1; the lower side plate 23 has a second clearance groove 230 extending toward the back plate 1 and penetrating from the inner surface of the lower side plate 22 to the outer surface on one end face away from the back plate 1; the depth of the first clearance groove 211 is less than the dimension of the upper side plate 21 along the depth direction z of the first clearance groove 211, and the depth of the second clearance groove 230 is less than the dimension of the lower side plate 23 along the depth direction z of the second clearance groove 230.

[0034] In this embodiment, the depth of the first clearance groove 211 is less than the dimension of the upper side plate 21 along the depth direction z, and the first clearance groove 211 is opened from the end face of the upper side plate 21 away from the back plate 1, so that the first clearance groove 211 does not penetrate the upper side plate 21 along the depth direction z. The depth of the second clearance groove 230 is less than the dimension of the lower side plate 23 along the depth direction z, and the second clearance groove 230 is opened from the end face of the lower side plate 23 away from the back plate 1, so that the second clearance groove 230 does not penetrate the lower side plate 23 along the depth direction z. On the one hand, the non-through portion of the upper side plate 21 and the non-through portion of the lower side plate 23 can increase the protective effect of the protective case 10 and its ability to secure electronic products. On the other hand, the setting of the first clearance groove 211 and the second clearance groove 230 can improve the ease of disassembly and assembly of the protective case 10. Furthermore, the setting of corresponding clearance grooves on the upper side plate 21 and the lower side plate 22 can further improve the ease of disassembly and assembly of the protective case 10. Moreover, the fact that the first clearance groove 211 does not penetrate the upper side plate 21 along the depth direction z and the second clearance groove 230 does not penetrate the lower side plate 23 along the depth direction z, so that the upper side plate 21 and the lower side plate 23 are continuously set, can improve the problem of the clearance grooves scratching the user's hands, thereby improving the user experience.

[0035] In some embodiments, at least a portion of the area of ​​the side panel of the frame 2 away from the back panel 1 can extend toward the inside of the frame 2 to form a latch, which is used to abut against the front face of the mobile phone to improve the fixation and protection of the electronic product.

[0036] In some embodiments, such as Figure 2 As shown, the width D1 of the first clearance groove 211 is smaller than the width D2 of the upper side plate 21; in some embodiments, such as Figure 3 As shown, the width D3 of the second clearance groove 230 is smaller than the width D4 of the lower side plate 23.

[0037] Wherein, the width of the upper side plate 21 refers to the dimension of the upper side plate 21 along the connection direction x with the left side plate 22 and the right side plate 24, and the width of the first clearance groove 211 refers to the dimension of the first clearance groove 211 along the connection direction x. The width of the lower side plate 23 refers to the dimension of the lower side plate 23 along the connection direction x with the left side plate 22 and the right side plate 24, and the width of the second clearance groove 230 refers to the dimension of the second clearance groove 230 along the connection direction x.

[0038] In this embodiment, the width D1 of the first clearance groove 211 is smaller than the width D2 of the upper side plate 21, meaning the first clearance groove 211 does not completely extend to cover the entire upper side plate 21. Reducing the width D1 of the first clearance groove 211 on the upper side plate 21 improves the protective case 10's ability to secure electronic products. The width D3 of the second clearance groove 230 is smaller than the width D4 of the lower side plate 23, meaning the second clearance groove 230 does not completely extend to cover the entire upper side plate 21. Reducing the width D3 of the second clearance groove 230 on the lower side plate 23 improves the protective case 10's ability to secure electronic products and also reduces the problem of the left and right edges of the second clearance groove 230 scratching the user's hands, thereby improving the user experience.

[0039] In some embodiments, the ratio between the width D1 of the first clearance groove 211 and the width D2 of the upper side plate 21 is 0.7 to 0.8.

[0040] If the width D1 of the first clearance groove 211 is too large, the protective shell 10 will be difficult to fix to the electronic product; if the width D1 of the first clearance groove 211 is too small, the protective shell 10 will be difficult to remove from the electronic product. This embodiment limits the ratio between the width D1 of the first clearance groove 211 and the width D2 of the upper side plate 21 to 0.7 to 0.8, which can better balance the ability of the protective shell 10 to fix the electronic product and the convenience of assembling and disassembling the protective shell 10 and the electronic product, thereby improving the user experience.

[0041] In some embodiments, the ratio between the width D1 of the first clearance groove 211 and the width D2 of the upper side plate 21 can be 0.7, 0.72, 0.74, 0.76, 0.78, 0.8, etc.

[0042] In some embodiments, the ratio between the width D3 of the second clearance groove 230 and the width D4 of the lower side plate 23 is 0.7 to 0.8.

[0043] If the width D3 of the second clearance groove 230 is too large, the protective shell 10 will be difficult to fix to the electronic product; if the width D3 of the second clearance groove 230 is too small, the protective shell 10 will be difficult to remove from the electronic product. This embodiment, by limiting the ratio between the width D3 of the second clearance groove 230 and the width D4 of the lower side plate 23 to 0.7 to 0.8, can better balance the ability of the protective shell 10 to fix the electronic product and the ease of assembling and disassembling the protective shell 10 and the electronic product, thereby improving the user experience.

[0044] In some embodiments, the ratio between the width D3 of the second clearance groove 230 and the width D2 of the upper side plate 21 can be 0.7, 0.72, 0.74, 0.76, 0.78, 0.8, etc.

[0045] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the upper side plate 21 is divided along the width direction x of the first clearance groove 211 into a first opening 201, a first connecting portion 202 located at one end of the first opening 201, and another first connecting portion 202 located at the other end of the first opening 201. The first opening 201 is recessed relative to the first connecting portion 202 toward the back plate 1 to form the first clearance groove 211. The lower side plate 23 is divided along the width direction x of the second clearance groove 230 into a second opening 2312, a second connecting portion 235 located at one end of the second opening 2312, and another first connecting portion 202 located at the other end of the second opening 2312. The second opening 2312 is recessed relative to the second connecting portion 235 toward the back plate 1 to form the second clearance groove 230.

[0046] The first clearance groove 211 can be completely disposed within the first opening 201, or it can be formed by the first opening 201 and the first connecting part 202 surrounding it; the second clearance groove 230 can be completely disposed within the second opening 2312, or it can be formed by the second opening 2312 and the second connecting part 235 surrounding it.

[0047] In this embodiment, the first clearance groove 211 is disposed in the middle region of the upper side plate 21 along the width direction x. First connecting portions 202 are respectively provided on both sides of the first clearance groove 211. This improves the ability of the protective shell 10 to fix and protect the electronic product, enhances the overall aesthetics, facilitates the avoidance of exposed parts on the electronic product, and facilitates the installation and removal of the protective shell 10. In this embodiment, the second clearance groove 230 is disposed in the middle region of the lower side plate 23 along the width direction x. Second connecting portions 235 are respectively provided on both sides of the second clearance groove 230. This improves the ability of the protective shell 10 to fix and protect the electronic product, enhances the overall aesthetics, facilitates the avoidance of exposed parts on the electronic product, and facilitates the installation and removal of the protective shell 10.

[0048] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, when the protective shell 10 is assembled onto the electronic product 5, at least the flat portion of the top of the electronic product 5 is exposed in the first clearance groove 211 along the width direction x; and the front end of the flat portion is flush with the rear end of the first clearance groove 211 along the depth direction z.

[0049] In this embodiment, along the depth direction z, the first clearance groove 211 is only provided corresponding to the arc-shaped surface 51 at the top of the electronic product 5, which can improve the fixing and protection capabilities of the electronic product 5.

[0050] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 , Figure 5 As shown, the top of the electronic product 5 includes an arc-shaped surface 51, and the end of the first clearance groove 211 extends just to the end point of the arc-shaped surface 51, that is, the front end of the flat portion. Furthermore, the width D1 of the first clearance groove 211 of the protective shell 10 is greater than or equal to the width of the flat portion at the top of the electronic product 5.

[0051] In some embodiments, such as Figure 2 As shown, the ratio of the depth of the first clearance groove 211 to the dimension H1 of the upper side plate 21 along the depth direction z of the first clearance groove 211 is 0.9 to 0.95.

[0052] The depth of the first clearance groove 211 is the difference between the dimension H1 of the upper side plate 21 along the depth direction z of the first clearance groove 211 and the distance H2 between the bottom wall of the first clearance groove 211 and the back plate 1.

[0053] The ratios in this embodiment may specifically include 0.9, 0.91, 0.92, 0.93, 0.94, and 0.95.

[0054] In some embodiments, the ratio of the depth of the second clearance groove 230 (excluding the depth of the charging port clearance groove 231) to the dimension of the lower side plate 23 along the depth direction z of the second clearance groove 230 is 0.9 to 0.95. The ratio may specifically include 0.9, 0.91, 0.92, 0.93, 0.94 and 0.95.

[0055] In some embodiments, such as Figure 2 As shown, the corner of the opening of the first clearance groove 211 is provided with a first rounded corner structure 204.

[0056] Setting the first rounded corner structure 204 can improve the situation where the corner of the first clearance groove 211 is too sharp and scratches the user's hand, thus improving the user experience.

[0057] In some embodiments, such as Figure 3 As shown, the corner of the opening of the second clearance groove 230 is provided with a second rounded corner structure 2311.

[0058] Setting a second rounded corner structure 2311 can improve the situation where the corners of the second clearance groove 230 are too sharp and could scratch the user's hands, thus improving the user experience.

[0059] In some embodiments, the radius of the second rounded corner structure 2311 ranges from 2mm to 3mm, specifically 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm, etc.

[0060] The depths mentioned above do not include the depths of rounded corner areas.

[0061] In some embodiments, the first connecting portion 202 extends inwardly from the side edge away from the back plate 1; the second connecting portion 235 extends inwardly from the side edge away from the back plate 1.

[0062] The first connecting portion 202 bends inward and extends towards the middle of the space enclosed by the frame 2, so that when the electronic product is assembled with the protective case 10, the second connecting portion 235 extends to the front of the electronic product, thereby improving the ability of the protective case 10 to fix the electronic product; the second connecting portion 235 bends inward and extends towards the middle of the space enclosed by the frame 2, so that when the electronic product is assembled with the protective case 10, the second connecting portion 235 extends to the front of the electronic product, thereby improving the ability of the protective case 10 to fix the electronic product.

[0063] In some embodiments, the opening may also bend inward and extend.

[0064] In some embodiments, the angle between the inner surface of the second region of the frame 2 and the inner surface of the back plate 1 is less than 90° to increase the constraint effect on the electronic product.

[0065] In some embodiments, such as Figure 6 As shown, the frame 2 is divided into a first region and a second region along the depth direction z. The first region is connected to the back plate 1, and the second region is connected to the side of the first region away from the back plate 1. The second region is perpendicular to the back plate 1. The second region of the upper side plate 21 or the second region of the lower side plate 23 is provided with a clearance groove 2111. The area of ​​the second region without the clearance groove 2111 bends inward on the side away from the first region to form a latch on the side of the clearance groove 2111. This structure increases the compatibility between the protective shell 10 and the electronic product, thereby improving the protection effect of the electronic product. Furthermore, the second region of the frame 2 is the open end region of the frame 2, which is perpendicular to the back plate 1. Only the latch bends inward, so that when the electronic product is placed in the receiving cavity, the frame 2, except for the latch, does not cover the front face of the electronic product, thus not affecting the panel display of the electronic product and improving the ease of loading and unloading.

[0066] In some embodiments, such as Figure 6 As shown, the edge of the first connecting portion 202 away from the back panel 1 bends inward to form a first latch 203; the edge of the second connecting portion 235 away from the back panel 1 bends inward to form a second latch 233. These latches enhance the bonding strength between the protective case 10 and the mobile phone, reducing the risk of the protective case 10 detaching from the electronic product.

[0067] The first latch 203 extends from the first connecting part 202 toward the middle of the receiving cavity. The first latch 203 can be arc-shaped and can be matched with the arc-shaped connection between the side and front face of the electronic product to improve the fit and fixation of the electronic product. The second latch 233 extends from the second connecting part 235 toward the middle of the receiving cavity. The second latch 233 can be arc-shaped and can be matched with the arc-shaped connection between the side and front face of the electronic product to improve the fit and fixation of the electronic product.

[0068] In some embodiments, the extension direction of the aforementioned latch can be adjusted according to the shape of the electronic product to limit the electronic product's orientation toward the back panel.

[0069] In some embodiments, the first latch 203 located on the left side of the first clearance groove 211 extends from the first connecting portion 202 on the left side to the left side plate 22, so that the first latch 203 is located at the upper left corner of the protective shell; the first latch 203 located on the right side of the first clearance groove 211 extends from the first connecting portion 202 on the right side to the right side plate 24, so that the first latch 203 is located at the upper right corner of the protective shell 10. Similarly, the second latches 233 located on both sides of the second clearance groove 230 are located at the lower left and lower right corners of the protective shell 10, respectively. With this structure, the fixing and protection effect of the protective shell 10 on the four corners of the electronic product 5 can be improved.

[0070] The width of the aforementioned latches ranges from 5mm to 15mm. In other embodiments, latches may also be provided in the middle region of the upper side plate 21, the left side plate 22, the lower side plate 23, and the right side plate 24.

[0071] In some embodiments, such as Figure 1 , Figure 3 , Figure 6 As shown, the bottom of the second clearance groove 230 is provided with a charging port clearance groove 231 extending from the inner surface to the outer surface of the lower side plate 23. The charging port clearance groove 231 communicates with the second clearance groove 230. The lower side plate 23 is also provided with at least one sound outlet clearance hole 232 spaced apart from the charging port clearance groove 231. The sound outlet clearance hole 232 is used to correspond to the sound outlet hole on the electronic product to avoid the sound outlet hole.

[0072] In this embodiment, the sound hole avoidance hole 232 is designed to be fully enclosed, and the charging port avoidance groove 231 and the sound hole avoidance hole 232 respectively avoid the charging port and the sound hole of the electronic product.
