[0024] The present application will now be described in detail with reference to the accompanying drawings.

[0025] To solve the above technical problems, combined with Figure 1 , Figure 3 and Figure 6B As shown in the illustration, this application provides a mobile terminal protective case, including a housing 1, a support structure 2, and an elastic wrist strap 3. The housing 1 can be fitted onto the mobile terminal to protect it. The side of the housing 1 facing away from the mobile terminal is the back 111. The support structure 2 is rotatably mounted on the back 111 of the housing 1. The support structure 2 can rotate relative to the housing 1 between a first position and a second position. When the support structure 2 rotates to the first position, it moves away from the housing 1 and can tilt the housing 1 to support it on a table or other load-bearing surface, making it convenient for the user to watch videos on the mobile terminal. When the support structure 2 rotates to the second position, it is attached to the housing 1, and the user can hold the mobile terminal by passing their fingers through the elastic wrist strap 3. The support structure 2 includes a support member 21 and at least two first positioning posts 22. The at least two first positioning posts 22 can be two in number, each positioned at one end of the support member 21; or they can be four in number, with two posts arranged in pairs at both ends of the support member 21, and so on. The number of first positioning posts 22 is not specifically limited, as long as they are distributed at both ends of the support member 21 to fix the first end 31 and the second end 32 of the elastic wristband 3. The elastic wristband 3 is an elastic, elongated sheet structure, including a first end 31 and a second end 32. First positioning holes 331 are provided on the first end 31 and the second end 32 of the elastic wristband 3 corresponding to each first positioning post 22. Each first positioning post 22 passes through the first positioning hole 331 and is then positioned, fixing the first end 31 and the second end 32 of the elastic wristband 3 to the support member 21. The user can then hold the mobile terminal by passing their fingers through the elastic wristband 3. The elastic hand strap 3 and the bracket structure 2 can be stably connected by the cooperation of the first positioning post 22 and the first positioning hole 331.

[0026] In one embodiment of this application, combined with Figure 3 , Figure 4 , Figure 6A and Figure 6B As shown, the bracket structure also includes a first mounting member 34 and a second mounting member 35. Preferably, the first mounting member 34 and the second mounting member 35 are sheet-like structures made of rigid material. At least one second positioning hole 36 is provided on each of the first mounting member 34 and the second mounting member 35. The number of second positioning holes 36 matches the number of first positioning posts 22 and first positioning holes 331. Each first positioning hole 331 is aligned and connected to each second positioning hole 36. Each first positioning post 22 passes through each first positioning hole 331 and then through each second positioning hole 36 for positioning, thereby pressing and fixing the first mounting member 34 onto the first end 31 of the elastic wristband 3, and pressing and fixing the second mounting member 35 onto the second end 32 of the elastic wristband 3, increasing the strength of fixing the elastic wristband 3.

[0027] In one embodiment of this application, combined with Figure 3 and Figure 4 As shown, the first mounting member 34 includes a main body 341 and a first positioning part 342 and a second positioning part 343 extending on both sides of the main body 341. A second positioning hole 36 is formed on the main body 341, and the shape of the main body 341 matches the first end 31 of the elastic wristband 3. The first positioning part 342 and the second positioning part 343 extend beyond the first end 31 of the elastic wristband 3. At least one third positioning hole 344 is formed on the first positioning part 342 and the second positioning part 343, and the number of third positioning holes 344 can be one, two, or three, etc. A second positioning post 23 protrudes from the support member 21 opposite to each third positioning hole 344. Each second positioning post 23 is respectively disposed through each third positioning hole 344. The first positioning part 342 and the second positioning part 343 can further compress the elastic wristband 3 and increase the strength of fixing the elastic wristband 3.

[0028] In one embodiment of this application, combined with Figure 2 , Figure 3 , Figure 4 and Figure 6BAs shown, the first positioning post 22 passes through the second positioning hole 36 and is riveted to form a first limiting structure 221. Since the first mounting member 34 and the second mounting member 35 are respectively pressed onto the first end 31 and the second end 32 of the elastic wristband 3, the maximum outer diameter of the first limiting structure 221 is larger than the diameter of the second positioning hole 36, preventing the first mounting member 34 and the second mounting member 35 from coming off the first positioning post 22, thus fixing the first end 31 and the second end 32 of the elastic wristband 3. Optionally, the maximum outer diameter of the first limiting structure 221 can also be larger than the diameter of the first positioning hole 331. In this case, the first end 31 and the second end 32 of the elastic wristband 3 can be fixed even without the first mounting member 34 and the second mounting member 35. The second positioning post 23 passes through the third positioning hole 344 and is riveted to form a second limiting structure 231. The maximum outer diameter of the second limiting structure 231 is larger than the diameter of the third positioning hole 344, thus fixing the first positioning part 342 and the second positioning part 343. In this application, the first positioning post 22 and the second positioning post 23 can be integrally formed with the support member 21 and are made of metal. During riveting, the ends of the first positioning post 22 and the second positioning post 23 can be pressed down directly using a riveting device. This can both tighten the elastic hand strap 3 and form the first limiting structure 221 and the second limiting structure 231, simplifying the manufacturing process.

[0029] In one embodiment of this application, combined with Figure 2 , Figure 3 and Figure 4 As shown, the mobile terminal protective case also includes a mounting base 4, which includes a first fixing member 41, a second fixing member 42, and a rotating shaft 43. The housing 1 includes a back plate 11. When the mobile terminal is installed in the mobile terminal protective case, the back 111, i.e., the surface of the back plate 11 facing away from the mobile terminal, is the back side. A mounting hole 15 is provided on the back plate 11 of the housing 1. A mounting platform 16 is provided near the mounting hole 15. The mounting platform 16 is formed by reducing the thickness of the two sides of the back plate 11. The first fixing member 41 and the second fixing member 42 are clamped on both sides of the mounting platform 16 and are flush with other positions of the back plate 11. One of the first fixing member 41 and the second fixing member 42 is provided with a plurality of fourth positioning holes 411, and the other is provided with a plurality of third positioning posts 421. Each third positioning post 421 passes through the fourth positioning hole 411 and is riveted and fixed, thereby fixing the first fixing member 41 and the second fixing member 42. A bushing 44 is provided at the opposite end of the first fixing member 41 and the first mounting member 34. The bushing 44 is rotatably sleeved on the rotating shaft 43. The bushing 44 and the rotating shaft 43 are located within the mounting hole 15 to realize the rotatable connection between the first fixing member 41 and the first mounting member 34, thereby realizing the rotation of the bracket structure 2. It can be understood that the above-mentioned first positioning part 342 and second positioning part 343 can also enhance the hinge strength formed by the first mounting member 34 and the first fixing member 41.

[0030] In one embodiment of this application, combined with Figure 3 , Figure 4 and Figure 5 As shown, the support member 21 has a first mounting groove 24. The first end 31 of the elastic wristband 3 and the main body 341 of the first mounting member 34 are disposed on the first mounting groove 24. The first mounting groove 24 has a first extension groove 26 and a second extension groove 27 extending from both sides. The first positioning part 342 is located in the first extension groove 26, and the second positioning part 343 is located in the second extension groove 27. When the wristband body 33 is stretched, a tensile force is generated along the length direction of the wristband body 33 and acts on the first mounting member 34. At this time, the first extension groove 26 can limit the first positioning part 342, and the second extension groove 27 can limit the second positioning part 343, thereby enhancing the fixing strength of the first mounting member 34 and the elastic wristband 3.

[0031] In one embodiment of this application, combined with Figure 3 and Figure 5 As shown, the support member 21 has a first mounting groove 24 and a second mounting groove 25 respectively facing the first end 31 and the second end 32 of the elastic wristband 3. Optionally, the support member 21 is annular, and the first mounting groove 24 and the second mounting groove 25 extend through the support member 21 in the radial direction, that is, the first mounting groove 24 and the second mounting groove 25 do not have groove walls in the radial direction of the support member 21. The first end 31 of the elastic wristband 3 is located in the first mounting groove 24, and the second end 32 of the elastic wristband 3 is located in the second mounting groove 25. The through extension of the first mounting groove 24 and the second mounting groove 25 can increase the area used to fix the elastic wristband 3, further increasing the fixing strength.

[0032] In a preferred embodiment of this application, such as Figure 3 and Figure 5 As shown, the number of first positioning posts 22 is set to four. Two first positioning posts 22 are spaced apart and protruded in the first mounting groove 24, and two first positioning posts 22 are similarly spaced apart and protruded in the second mounting groove 25. During assembly, the first end 31 and the second end 32 of the elastic wristband 3 are respectively sleeved and fixed to the corresponding first positioning posts 22 through the first positioning holes 331 on them. The symmetrical distribution design of the first positioning posts 22 can evenly distribute the stress on the elastic wristband 3 during the stretching process, avoiding deformation or breakage caused by local stress concentration. In addition, the spacing between the first positioning posts 22 can be adaptively adjusted according to the material of the elastic wristband 3, such as silicone, TPU or elastic fabric, and the expected tensile strength, thereby further optimizing durability and stability.

[0033] In one embodiment of this application, combined with Figure 6A , Figure 6B and Figure 6CAs shown, the elastic wristband 3 includes a wristband body 33 and reinforcing members 37 respectively disposed at both ends of the wristband body 33. The reinforcing members 37 are made of a rigid material, such as aluminum alloy, iron, or other metals. In one configuration, the reinforcing member 37 is sheet-shaped and fits snugly onto the outer surface 332 of the end of the wristband body 33, or is embedded within the end of the wristband body 33. The rigid reinforcing member 37 increases the strength of the end of the wristband body 33, preventing the end of the wristband body 33 from being stretched and deformed. In another configuration, the reinforcing member 37 has at least a U-shaped portion to wrap around and clamp the outer surface 332 of the end of the wristband body 33. This avoids exposing the end of the wristband body 33 while also ensuring uniform force distribution at the end of the wristband body 33.

[0034] In one embodiment of this application, combined with Figure 3 and Figure 5 As shown, the support body 21 is also provided with at least one magnetic groove 28, which extends along the circumferential direction of the support body 21. Preferably, there are two magnetic grooves 28, which are spaced apart from the first mounting groove 24 and the second mounting groove 25 to form a spacer 29. The bracket structure 2 also includes a magnetic member 211, which is housed in the magnetic groove 28 and can magnetically attach the mobile phone inside the housing 1 to the magnetic charging holder or car mount for magnetic charging. By setting the spacer 29 to be spaced apart from the first mounting groove 24 and the second mounting groove 25, the deformation of the magnetic groove 28 is prevented when the wrist strap body 33 is stretched and deformed, thus reducing stress transmission. At the same time, the spacer 29 can also increase strength and prevent transitional deformation between the inner and outer edges of the support body 21.

[0035] In one embodiment of this application, combined with Figure 3 and Figure 5As shown, the thickness of the first end 31 of the elastic wristband 3 is equal to the depth of the first mounting groove 24, and the thickness of the second end 32 of the elastic wristband 3 is less than the depth of the second mounting groove 25. This ensures that when the support member 21 is attached to the back 111 of the housing 1, the elastic wristband 3 will not protrude excessively, affecting the user's grip experience. The depth of the first mounting groove 24 refers to the vertical height from the bottom surface of the first extension groove 26 to the bottom surface of the first mounting groove 24, and the depth of the second mounting groove 25 refers to the vertical height from the surface of the spacer 29 to the bottom surface of the second mounting groove 25. In other embodiments, the thickness of the first end 31 of the elastic wristband 3 is greater than the depth of the first mounting groove 24, and the thickness of the second end 32 of the elastic wristband 3 is equal to the depth of the second mounting groove 25. This allows for a certain deformation allowance at the first end 31 and the second end 31 of the elastic wristband 3, enabling the first mounting member 34 and the second mounting member 35 to respectively compress the first end 31 and the second end 31 to produce elastic deformation, thereby increasing the stability of the connection between the elastic wristband 3 and the support member 21. It should be understood that the relationship between the thickness of the first end 31 and the depth of the first mounting groove 24, and the relationship between the thickness of the second end 32 and the depth of the second mounting groove 25, can be combined and set according to the actual design requirements of the product.

[0036] In one embodiment of this application, combined with Figure 3 and Figure 5 As shown, the support structure 2 also includes an annular cover 210, which is a thin plastic sheet. The shape of the cover 210 is adapted to the shape of the support member 21 so as to cover the support member 21. The cover 210 can cover the first mounting groove 24, the second mounting groove 25, and at least one magnetic groove 28, thereby also covering and protecting the elastic wrist strap 3 and the magnetic member 211, increasing the aesthetics.

[0037] In one embodiment of this application, combined with Figure 2 As shown, a support platform 12 is provided on the back 111 of the housing 1. A recessed bracket receiving groove 13 is arranged around the periphery of the support platform 12. The shape and size of the bracket receiving groove 13 match the bracket structure 2, ensuring that when the bracket structure 2 is rotated to fit against the back 111 of the housing 1, it can be accommodated in the bracket receiving groove 13, thereby maintaining the flatness of the back 111 of the housing 1 and avoiding improper protrusions that affect the grip. At the same time, a hand strap receiving groove 14 is also provided along the length direction of the housing 1 on the platform 12. When the bracket structure 2 is closed, the elastic hand strap 3 fits against the back 111 of the housing 1 and can be accommodated in the hand strap receiving groove 14. The elastic hand strap 3 is arranged along the length direction of the housing 1, making it convenient for users to insert their fingers from the width direction, which conforms to user habits.

[0038] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
