Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0035] like Figure 1-3 As shown, this utility model provides a protective shell, including a first connector 1, a second connector 2, and an adjustment strap 3. The adjustment strap 3 is elastically connected between the first connector 1 and the second connector 2 so that the first connector 1 and the second connector 2 enclose and form a receiving cavity 8 for installing a mobile device 4. In use, the mobile device 4 is installed in the receiving cavity 8. The adjusting strap 3 pulls the first connecting member 1 and the second connecting member 2 towards the center of the mobile device 4, so that the first connecting member 1 and the second connecting member 2 are tightly attached to the outer peripheral wall of the mobile device 4. Moreover, through the elastic stretching of the adjusting strap 3, the first connecting member 1 and the second connecting member 2 form receiving cavities 8 of different sizes to adapt to mobile devices 4 of different sizes. Traditional protective cases must be molded and produced separately for mobile devices such as tablets / phones of different sizes and models. However, this design allows the same protective case to adapt to mobile devices of multiple sizes by adjusting the length or tension of the adjusting strap 3. This saves costs. When installing or removing the protective case, only the adjusting strap 3 needs to be adjusted to remove the mobile device 4 from the receiving cavity 8. This design is easy to carry, convenient and compact, with a simple structure and no need for complicated and cumbersome adjustments.

[0036] Specifically, such as Figure 3 As shown, the first connector 1 and the second connector 2 are provided with grooves 5 for wrapping the four corners of the mobile device 4. The grooves 5 can precisely engage the corners, providing the primary and most critical fixing points for the protective shell. When installing, the user can first accurately insert two corners into the grooves 5, and then stretch the adjustment strap 3 to insert the other two corners of the mobile device 4 into the connectors, making installation and disassembly very convenient.

[0037] Furthermore, such as Figure 4-10 As shown, the first protective component includes a split or integrally formed corner protector 11 and a corner protector 2 12, and the second protective component includes a split or integrally formed corner protector 3 21 and a corner protector 4 22.

[0038] One embodiment of this application is as follows: Figure 3-5 As shown, corner protector 11 and corner protector 22 are separate and independently molded structures, as are corner protector 31 and corner protector 42. The grooves 5 of corner protector 11 and corner protector 22 are symmetrically distributed. The adjusting band 3 includes two bands, one of which connects corner protector 11 and corner protector 31, and the other of which connects corner protector 21 and corner protector 42. The grooves 5 of corner protector 31 and corner protector 42 are symmetrically distributed. The four corner protectors are completely independent and can dynamically adapt to the length, width, and aspect ratio of different flat plates after being connected by the two adjusting bands 3. Since corner protector 11 and corner protector 212 are independent, the lateral distance between them is variable; the same is true for corner protector 31 and corner protector 42. The two adjusting bands 3 independently control the tightness of the wrapping at the top and bottom ends, causing the corner protectors to converge towards the center.

[0039] like Figure 5 As shown, when the first corner protector 11 and the fourth corner protector 22 are arranged on the same side, and the third corner protector 21 and the second corner protector 12 are arranged on the same side, the two adjustment straps 3 intersect to form an "X" shape. The intersection of the "X" shape naturally becomes a dynamic central anchor point. When the adjustment straps 3 are tightened, this intersecting structure generates a tightening force converging towards the geometric center of the device, causing the tablet / phone and other mobile devices 4 to more evenly and naturally converge and lock towards the center, resulting in a stronger sense of enclosure. The two adjustment straps 3 can also form a figure-eight structure, such as... Figure 6 As shown.

[0040] like Figure 7 As shown, when the first corner protector 11 and the third corner protector 21 are arranged on the same side, and the second corner protector 12 and the fourth corner protector 22 are arranged on the same side, that is, the third corner protector 21 and the fourth corner protector 22 exchange positions, and the third corner protector 21 and the fourth corner protector 22 rotate 90 degrees (the two rotate in opposite directions), the two adjustment straps 3 form a figure-eight structure. If the two adjustment straps 3 are parallel, the protective shell can only provide clamping force perpendicular to the side of the equipment. When the equipment is subjected to lateral (left and right) force, or when torsion occurs, the plate can easily slide or rotate laterally within the corner protectors. The figure-eight structure introduces lateral constraint force. When the adjustment straps 3 are tightened, the equipment is firmly "locked" in the center of the frame formed by the four corner protectors, which greatly enhances the protective shell's ability to resist lateral impact and torsional load. No matter how the equipment shakes, it is difficult to come out of the corner protectors.

[0041] like Figure 8-9As shown, the second embodiment of this application is as follows: The first connector 1 is integrally formed by corner protector 11 and corner protector 22; the second connector 2 includes two independent corner protectors 31 and 42; one adjustment strap 3 connects one end of the first connector 1 to corner protector 31, and the other adjustment strap 3 connects the other end of the first connector 1 to corner protector 42, forming a cross-shaped X-shaped structure, or, one end of the first adjustment strap 3 connects to corner protector 321, one end of the second adjustment strap 3 connects to corner protector 42, the other end of the first adjustment strap 3 is connected and fixed to the other end of the second adjustment strap 3, one end of the third adjustment strap 3 connects to the first connector 1, and the other end connects to the connection and fixing point of the first adjustment strap 3 and the second adjustment strap 3, forming a herringbone structure; when installing, the user can first insert the tablet into the bottom integral connector, and then stretch the adjustment strap 3 to attach the two top corner protectors. The operation steps are clear and simple, and this design can adapt to mobile devices 4 of different widths / lengths.

[0042] The third embodiment of this application is as follows: Figure 10-11 As shown, the first connector 1 includes two independently formed corner protectors 11 and 22; the second connector 2 is integrally formed by corner protector 3 21 and corner protector 4 22; one adjustment strap 3 connects corner protector 11 to one end of the second connector 2, and another adjustment strap 3 connects corner protector 2 12 to the other end of the second connector 2, forming an intersecting X-shaped structure; or, one end of the first adjustment strap 3 connects to corner protector 11, one end of the second adjustment strap 3 connects to corner protector 2 12, and the other end of the first adjustment strap 3 is fixedly connected to the other end of the second adjustment strap 3; one end of the third adjustment strap 3 connects to the second connector 2, and the other end connects to the fixed connection point of the first and second adjustment straps 3, forming a herringbone structure. When installing, the user can first insert the tablet into the bottom integrated connector, which is easy to align, and then stretch the adjustment strap 3 to snap the two top corner protectors in place. The operation steps are clear and simple, and this design can adapt to mobile devices 4 of different widths / lengths.

[0043] like Figure 12 The fourth embodiment of this application is as follows: The first connector 1 is integrally formed by the first corner protector 11 and the second corner protector 12, and the second connector 2 is integrally formed by the third corner protector 21 and the fourth corner protector 22. The first connector 1 and the second connector 2 are connected by an adjustment strap 3. The user only needs to stretch the adjustment strap 3 to insert the device into the two connectors to adjust the length / width accordingly.

[0044] Preferably, the adjustment band 3 is one or a combination of elastic band, elastic braided band, retractable locking band, Velcro, spring, or elastic band. In this embodiment, the adjustment band 3 is an elastic band. The user only needs to clip the corner protector around the plate, and the natural rebound force of the elastic band will automatically tighten the protective shell on the device without any additional steps such as adjustment buckles or Velcro. This makes it easy to install, disassemble, and adjust. At the same time, the protective shell can be easily removed when it is not needed. The structure is compact and easy to carry.

[0045] Preferably, the first connector 1 and the second connector 2 are made of lightweight and high-strength materials. Since the mobile device 4, such as a tablet or mobile phone, already has a certain weight, using lightweight materials (such as high-performance engineering plastics PC / ABS, modified nylon, or carbon fiber composite materials) can reduce the overall weight of the protective case. The lightweight protective case makes the device easier to carry, which meets the essential needs of the mobile device 4.

[0046] like Figure 13 As shown, the adjustment band 3 is connected to the first connector 1 and the second connector 2 by a buckle 7. The adjustment band 3 is fastened to the first connector 1 and the second connector 2 by the buckle 7. Alternatively, it can be connected by adhesive, screws, or other methods.

[0047] Specifically, such as Figure 2 and 12 As shown, the first connector 1 and the second connector 2 are provided with functional holes 14 adapted to the mobile device 4; the functional holes 14 are used to provide access channels for one or more of the mobile device 4's camera, charging port, speaker, microphone and physical buttons, so as to ensure that the protective case does not affect the normal use of its original functions when covering the device.

[0048] Furthermore, such as Figure 2 and 14 As shown, it also includes a bracket 6 rotatably connected to the first connector 1 and / or the second connector 2. The bracket 6 is provided with a rotating shaft 61. The rotating shaft 61 can be integrally formed with the main body of the bracket 6 through injection molding, or it can be manufactured separately from the bracket 6 as an independent component and then assembled. The first connector 1 and / or the second connector 2 are provided with a connecting hole 13 adapted to the rotating shaft 61. The rotating shaft 61 is inserted into the connecting hole 13 so that the first connector 1 / second connector 2 is rotatably connected to the bracket 6. The bracket 6 is also provided with an elongated hole 62. When in use, the user can hold the bracket 6 by passing his hand through the elongated hole 62, and thus carry the protective shell connected to the bracket 6 and the mobile device 4 mounted on the protective shell.

[0049] The mobile device 4 can be a mobile phone, computer, tablet, or other similar device.

[0050] like Figure 14-15 As shown, in this embodiment, the bracket 6 is rotatably connected to the first connector 1. When the first corner protector 11 and the second corner protector 12 are designed separately, the third corner protector 21 and the fourth corner protector 22 are also designed separately. In use, the connecting hole 13 on the first corner protector 11 is inserted into one end of the rotating shaft 61, and the connecting hole 13 on the second corner protector 12 is inserted into the other end of the rotating shaft 61. In this way, a single rotating shaft 61 structurally connects the two originally separate corner protectors 11 and the second corner protector 12, and forms a stable rotating connection pair with the bracket 6. In use, the bracket 6 can be rotated at a certain angle so that the mobile device 4 mounted on the corner protector forms an angle with the bracket 6 to support the mobile device 4. The tilt at a certain angle makes it easier to view the screen of the mobile device 4 without holding it, freeing the user's hands. Whether working on a desktop, looking at recipes in the kitchen, or making a video call, it can provide the best viewing posture, greatly improving the productivity and entertainment experience of the tablet computer.

[0051] The following is a detailed explanation of the working principle of this utility model; In use, stretch the adjustment strap to engage the four corners of the mobile device with the corner protectors of the first and second connectors. The split corner protector design allows for dynamic changes in the lateral distance between the corner protectors, and combined with the elasticity of the adjustment strap, it adapts to changes in the width and length of devices of different sizes. The user rotates the stand around its pivot point to form a specific angle with the back of the device. At this point, the stand, the device, and the desktop form a stable triangular support structure, firmly supporting the device on the desktop. This is suitable for scenarios such as office work, watching movies, and video calls. Simultaneously, the user can safely and comfortably carry the protective case containing the device by passing their hand through the elongated hole on the stand, just like holding a handle, avoiding the problem of the tablet easily slipping when gripped by bare hands. The innovation of this utility model lies in the fact that the protective shell is composed of a first connecting member, a second connecting member, and an adjusting strap. By adjusting the length or tension of the adjusting strap, the same protective shell can be adapted to mobile devices of different sizes without the need for separate molds for different devices. The first and second protective members can be designed as separate or integral molded structures, and the corner protectors are connected by the adjusting strap to form a dynamic wrapping system that adapts to changes in the length, width, and proportion of different devices. By arranging the adjusting straps in a "figure-eight" or "X" shape, the lateral restraint force and central convergence effect on the device are enhanced, effectively preventing the device from sliding or rotating within the corner protectors and improving the stability of the protection. The bracket can rotate at a certain angle to support the device, freeing the user's hands. The elongated hole on it can be directly used as a handle, making it convenient for users to hold and carry the entire device, greatly improving the convenience of mobile use.
