Detailed Implementation

[0029] This invention analyzes the reasons for the short lifespan of existing protective shells with embedded supports in soft materials. It finds that the lifespan of such shells typically ends with the habitual detachment of the embedded support. Observation reveals that this habitual detachment is mainly caused by deformation or breakage at the connection point between the support and the shell. Further analysis shows that when using an electronic device bracket for support, the bracket continuously exerts a pulling force on the connection point outwards from the protective shell, causing continuous slight deformation at the connection point. Consequently, under long-term stress, the plastic at the connection point gradually deforms, eventually leading to permanent deformation and ultimately the habitual detachment of the electronic device bracket.

[0030] To address the aforementioned issues, this invention is conceived to increase the rigidity of the joint between the electronic device bracket and the protective shell. By adding a bracket connection part 20 made of a harder material as the joint between the bracket and the protective shell, the degree of deformation of this part during use is reduced, thereby reducing the stress on the plastic in this part. This, in turn, can delay the occurrence of permanent deformation of the plastic in the joint and extend the service life of the protective shell.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the protective case of this utility model includes a back plate, side frames 12 disposed on the back plate, and a bracket 32. The back plate and side frames 12 together form an accommodating cavity for accommodating electronic devices and fixing the protective case to the electronic devices. The bracket 32 ​​is rotatably connected to the back plate and has an open state and a closed state. When open, it can be used to support electronic devices, and when closed, it is convenient for carrying and use.

[0033] Specifically, the back plate includes a main body 11 and a support connecting part 20. The main body 11 and the support connecting part 20 together constitute the back plate, and the hardness of the support connecting part 20 is greater than that of the main body 11. For example... Figure 4The main body part 11 of the back plate is provided with a mounting hole 111, and the inner side wall of the mounting hole 111 is provided with a clamping groove 112. The clamping groove 112 includes an outer side groove wall 112a and an inner side groove wall 112b. The outer side groove wall 112a is closer to the outer surface of the support connecting part 20. The outer side groove wall 112a and the inner side groove wall 112b both extend towards the radial direction of the mounting hole 111, and the extension length of the outer side groove wall 112a is greater than that of the inner side groove wall 112b. The surface of the outer side groove wall 112a towards the inner side groove wall 112b is a bevel, which inclines towards the outer surface of the support connecting part 20 from the groove bottom to the opening of the clamping groove 112. The outer surface of the support connecting part 20 is the surface of the support connecting part 20 towards the outside of the protective shell accommodating cavity.

[0034] As shown in Figure 3 , Figure 5 , Figure 6 The support connecting part 20 is installed in the mounting hole 111, and the outer side wall of the support connecting part 20 is provided with a clamping convex 22 which cooperates with the clamping groove 112 and is clamped in the clamping groove 112. The outer surface of the support connecting part 20 is provided with an accommodating groove 23, and the support is rotatably connected with the support connecting part 20 through a connecting structure, and the support can be accommodated in the accommodating groove 23. The side wall of the accommodating groove 23 is provided with a first clamping spring mounting groove 24.

[0035] In this embodiment, the clamping convex 22 is arranged around the outer side wall of the support connecting part 20, and the clamping groove 112 is arranged around the inner side wall of the mounting hole 111, thereby increasing the connection strength between the support connecting part 20 and the back plate main body. Further, in another embodiment, the support connecting part 20 is first injection molded, and then the back plate and the side frame 12 are integrally molded on the support connecting part 20 by injection molding. Further, in an embodiment, the main body part 11 of the back plate and the side frame 12 are preferably made of thermoplastic polyurethane rubber (TPU), and the support connecting part 20 is made of polycarbonate (PC).

[0036] The support 32 is rotatably connected with the support connecting part 20 through a connecting structure, and the support 32 can be accommodated in the accommodating groove 23. As shown in Figure 1 , Figure 3 , Figure 6 , Figure 7As shown, the connecting structure includes a connecting seat 31, a rotating shaft 33, and a retaining ring 40. In this embodiment, the connecting seat 31 is annular and disposed within the receiving groove 23, with a second retaining ring mounting groove 312 on its outer side wall. The second retaining ring mounting groove 312 is positioned opposite to the first retaining ring mounting groove 24. The retaining ring 40 is disposed within the space enclosed by the first retaining ring mounting groove 24 and the second retaining ring mounting groove 312, allowing the connecting seat 31 to rotate within the receiving groove 23. The bracket 32 ​​is rotatably connected to the connecting seat 31 via the rotating shaft 33. Furthermore, the bracket 32 ​​has a notch 321 on the side away from the rotating shaft 33, facilitating the removal of the bracket from the mounting groove.

[0037] The protective shell provided by this utility model is fitted onto the electronic device, such as... Figure 1 and Figure 3 As shown, when bracket 32 ​​is not needed, it is rotated around pivot 33 until it overlaps with connector 31. At this time, bracket 32 ​​is housed within receiving groove 23, reducing the height of bracket 32 ​​protruding from the back plate; bracket 32 ​​is in its closed state at this time. Figure 7 As shown, when the bracket 32 ​​is needed to support the electronic device, the bracket 32 ​​is rotated around the pivot 33 until it forms an angle with the connecting seat 31. At this time, the bracket 32 ​​is in the open state, and the electronic device can be placed on the table, using the angle of the bracket 32 ​​to make the electronic device stand at an angle on the table. At the same time, the bracket can be rotated to adjust the angle to a suitable position and direction. In addition, since the extension length of the outer groove wall 112a of the slot 112 is greater than the extension length of the inner groove wall 112b, the outer groove wall 112a covers the latching protrusion 22 of the connection part 20 with the bracket, which improves the aesthetics of the protective shell and also increases the strength of the outer side of the mounting hole 111 of the back plate 11, reducing the probability of breakage.

[0038] Furthermore, this invention discovered that during use, the bracket 32 ​​easily rotates relative to the pivot 33, leaves the mounting slot, and swings freely, interfering with the carrying and use of electronic devices when the bracket 32 ​​is not needed. Therefore, this invention makes improvements, such as... Figure 3 and Figure 6 As shown, the connector 31 is made of metal, and a magnet 322 is embedded in the bracket 32. Specifically, as... Figure 6 and Figure 7As shown, the surface of the support 32 opposite to the connecting seat 31 is provided with a magnet 322 setting groove, and the groove is placed with a magnet 322, and the slot is pasted with a support Mylar sheet 323. The support Mylar sheet 323 fixes the magnet 322 in the magnet 322 setting groove, and shields the magnet 322. Two pieces of support Mylar sheet 323 are overlapped and pasted in the slot of the embodiment, which is used to reduce the shaking space of the magnet 322 in the magnet 322 setting groove to avoid impact. When the support 32 is not needed, the support 32 is placed in the setting groove and can be tightly attached to the connecting seat 31 under the magnetic force of the magnet 322, and no longer uncontrollably separates from the setting groove and freely shakes, which hinders the use of the electronic device. Only when the user exerts force to scratch the notch 321 of the support 32 can the support leave the setting groove.

[0039] Further, in the process of using the above protective shell, the present application finds that the accommodating groove 23 bottom of the support connecting part 20 wears faster under the repeated rotation and friction of the support 32; in addition, the support connecting part 20 with relatively hard material can contact the back of the electronic device, which also causes wear to the electronic device. Therefore, the present application is improved, as shown in Figure 2 and Figure 6 As shown: on the one hand, a wear-resistant sheet 313 setting groove is arranged on the side of the connecting seat 31 in contact with the bottom of the accommodating groove 23 of the support connecting part 20, and the wear-resistant sheet 313 is arranged in the groove. Then the wear-resistant sheet 313 is located between the connecting seat 31 and the support connecting part 20, which slightly pads the connecting seat 31 from the bottom of the accommodating groove 23, so that it does not directly contact the bottom of the accommodating groove 23 of the support connecting part 20. When the connecting seat 31 rotates in the accommodating groove 23, it mainly rubs with the wear-resistant sheet 313, which can reduce the friction between the connecting seat 31 and the support connecting part 20.

[0040] On the other hand, as shown in Figure 3 and Figure 6As shown, the thickness of the bracket connecting part 20 is slightly thinner than the back plate, so that the inner surface of the bracket connecting part 20 is lower than the inner surface of the main body part 11. When the protective case is fitted on the electronic device, the inner side surface of the bracket connecting part 20 towards the inside of the protective case is spaced apart from the electronic device, so that the relatively hard bracket connecting part 20 does not directly contact the protective case, thereby reducing the abrasion of the electronic device. Meanwhile, the inner side Mylar sheet 50 is additionally arranged on the inner surface of the bracket connecting part 20 facing the inside of the accommodating cavity. The inner surface of the inner side Mylar sheet 50 is the surface facing the inside of the accommodating cavity of the protective case. When the inner side Mylar sheet 50 is arranged on the inner surface of the bracket connecting part 20, the inner surface of the inner side Mylar sheet 50 is flush with the inner surface of the main body part 11. When the protective case is fitted on the electronic device, the inner side Mylar sheet 50 is located between the electronic device and the bracket connecting part 20, so that the bracket connecting part 20 does not directly contact the electronic device, and functions as a buffer, thereby reducing the abrasion of the electronic device by the protective case. Meanwhile, since the inner surface of the inner side Mylar sheet 50 is flush with the inner surface of the back plate, the inner side Mylar sheet 50 does not protrude from the back plate, so that the abrasion of the electronic device by the inner side Mylar sheet 50 is extremely low.

[0041] In one embodiment, the inner side Mylar sheet 50 completely covers the inner surface of the bracket connecting part 20, thereby maximizing the anti-abrasion effect.

[0042] In one embodiment, the inner side Mylar sheet 50 has a ring structure, and when the inner side Mylar sheet 50 is arranged on the inner surface of the bracket connecting part 20, the inner side Mylar sheet 50 and the bracket connecting part 20 form a placing groove, and at least one groove member 60 can be placed in the placing groove. The ring structure can be a single ring-shaped inner side Mylar sheet 50, or can be a ring structure formed by a plurality of inner side Mylar sheets 50.

[0043] The inner surface of the inner part 60 towards the inner side of the accommodating cavity is flush with the inner surface of the inner side Mylar sheet 50; the size and shape of the inner part 60 are adapted to the size and shape of the placing slot, and can fill the inner space of the placing slot. The inner surface of the inner part 60 towards the inner side of the mobile phone case is the inner surface. The inner surface of the inner part 60 is flush with the inner surface of the inner side Mylar sheet 50. The inner part 60 is one or more of a decorative sheet, a sticker, an anti-friction sheet, a magnetic part, a sachet, and a mirror. When there are at least two inner parts 60, each of the inner parts 60 can be the same or different. When the mobile phone case with the inner part 60 is put on the mobile phone, the back of the mobile phone blocks the slot of the placing slot, and the inner part 60 is enclosed in the placing slot, so that it cannot fall out. Further, the support connecting part 20 is a transparent structure made of PC material, and the material of the main body part 11 and the side frame 12 is the same: in one embodiment, both are transparent TPU material, and in another embodiment, both are non-transparent TPU material. Therefore, the inner part 60 in the placing slot can be seen through the transparent support connecting part 20 from the outside, increasing the aesthetic appearance of the protective case.

[0044] Specifically, in one embodiment, a decorative sheet with a size and shape adapted to the placing slot is placed in the placing slot. After the decorative sheet is put into the placing slot, it can fill the inner space of the placing slot, and the inner surface of the decorative sheet is flush with the inner surface of the inner side Mylar sheet 50. One side of the decorative sheet has a decorative pattern, and the patterned side is attached to the support connecting part 20. Since the support connecting part 20 is transparent, the pattern of the decorative sheet can be seen through the transparent support connecting part 20 from the outside of the protective case.

[0045] In one embodiment, the inner part 60 is two identical decorative sheets stacked together. The cross-sectional shape of each decorative sheet is adapted to the shape of the placing slot, and the height is half of the height of the placing slot, so that when the two decorative sheets are stacked together, the size and shape are adapted to the size and shape of the placing slot, and can exactly fill the placing slot. At this time, the side of the decorative sheet located at the slot of the placing slot towards the inner side of the accommodating cavity of the protective case is the inner surface of the inner part 60, and the inner surface of the inner part 60 is flush with the inner surface of the inner side Mylar sheet 50. The patterns of the two decorative sheets are respectively towards the outer side and the inner side of the accommodating cavity of the protective case, so that the same pattern can be seen from the inner side and the outer side of the protective case. Further, the two decorative sheets are different decorative sheets, specifically with different patterns, so that different patterns can be seen from the inner side and the outer side of the protective case. The user can replace the inner part 60 in the placing slot according to needs, increasing the aesthetic appearance and interest of the protective case.

[0046] In one embodiment, a sticker is attached in the placing groove, the size and shape of the sticker are adapted to the size and shape of the placing groove, the sticker is attached on the inner surface of the support connecting part 20, the inner surface of the sticker is the surface facing the inner side of the protective shell accommodating cavity, and the inner surface of the sticker is flush with the inner surface of the inner side mylar sheet 50. The sticker can be firmly attached on the support connecting part 20 whether the protective shell is sleeved on the electronic device or not. If the sticker has patterns on both surfaces, the patterns of the sticker can be seen from the inner side and the outer side of the protective shell, and the aesthetic appearance of the protective shell is further increased.

[0047] Further, in one embodiment, the inner piece 60 in the groove is two half-circular stickers, the two half-circular stickers can be combined into a circular sticker, and the circular sticker is attached in the placing groove to fill the entire placing groove as a whole. The thickness of each sticker is the same as the thickness of the placing groove. If the two stickers have different patterns, two different half-circular patterns can be seen in the circular placing groove.

[0048] In one embodiment, three different inner pieces 60 are sequentially stacked in the placing groove, and the three different inner pieces 60 are a circular decorative sheet, a magnetic piece and an anti-friction sheet. The decorative sheet is attached to the inner surface of the support connecting part 20, and the pattern of the decorative sheet can be seen from the outer side of the protective shell through the transparent support connecting part 20. The magnetic piece is attached on the decorative sheet and located between the decorative sheet and the anti-friction sheet. The anti-friction sheet is attached on the magnetic piece and located in the slot of the placing groove. In the stacked state, the anti-friction sheet, the magnetic piece and the decorative sheet jointly serve as an inner piece 60 to fill the inner space of the placing groove. The magnetic piece can be used for adsorption and fixation during wireless charging. The decorative sheet has the functions of blocking and aesthetics, so that the magnetic piece cannot be seen from the outer side of the protective shell. The anti-friction sheet is located between the electronic device and the magnetic piece to prevent the magnetic piece from rubbing the electronic device, and the practicability of the protective shell is increased.

[0049] In one embodiment, a mirror is placed in the placing groove, and the mirror surface faces the inner surface of the support connecting part 20. When the protective shell is sleeved on the electronic device, the user can use the mirror from the outer side of the protective shell through the support connecting part 20, and the practicability of the protective shell is increased.

[0050] In one embodiment, a flat sachet is placed in the placing groove to fill the placing groove, and the surface of the sachet has patterns, which can be seen from the inner side and the outer side of the protective shell, so that the interestingness and the aesthetic appearance of the protective shell are increased.

[0051] Compared with the prior art, the protective shell has the following advantages:

[0052] 1. Using a rigid bracket connector 20 as the fitting part between the bracket and the back plate, compared with a soft back plate, the rigid bracket connector 20 has less deformation when connecting the bracket, so the material of the bracket connector 20 is subjected to less stress, which can slow down the occurrence of permanent deformation of plastic and extend the service life of the protective case.

[0053] 2. The back plate is integrally injection molded onto the bracket connection part 20, increasing the connection strength between the bracket and the housing. At the same time, the extension length of the outer groove wall 112a of the slot 112 towards the mounting hole 111 is greater than the extension length of the inner groove wall 112b, which also increases the material strength of the outer surface of the mounting hole 111 and reduces the probability of breakage.

[0054] 3. By embedding magnets 322 on the stand, the stand is prevented from shaking, improving the convenience of carrying the protective case.

[0055] 4. By adding an inner Mylar sheet 50 that is flush with the inner surface of the back panel, the rigid bracket connection part 20 is prevented from directly contacting the electronic device, reducing the wear of the protective shell on the electronic device and further protecting the electronic device.

[0056] 6. The inner Mylar sheet 50 of the ring and the bottom plate of the transparent bracket connection part 20 form a placement groove for placing the inner part 60 of the groove, so that the inner part 60 of the groove can be seen from both the inside and outside of the protective case. Users can freely replace the inner part 60 of the groove according to their needs, which increases the aesthetics, fun and practicality of the protective case.
