Description

Technical Field

[0001] This utility model relates to the field of smart terminal technology, and in particular to a terminal bracket and protective shell. Background Technology

[0002] A terminal stand is a structure that is installed on the back of a smart terminal (such as a mobile phone or tablet computer). The base and flip frame of the terminal stand are set at an angle to form a support structure, which allows the smart terminal to be placed at an angle on a flat surface such as a desktop, providing users with a better viewing angle.

[0003] However, the angle that the flipping frame can rotate relative to the base is limited. If the flipping frame continues to rotate beyond the maximum angle that can be rotated, it is easy to cause the base to deform or even cause the rotating connection between the flipping frame and the base to break, resulting in a short service life for the terminal bracket. Utility Model Content

[0004] This utility model discloses a terminal bracket and a protective shell. When the flip frame rotates more than the maximum angle relative to the base, the anti-fracture component can undergo elastic deformation to prevent the base from deforming and to prevent breakage at the rotational connection between the flip frame and the base. This results in a longer service life for the terminal bracket.

[0005] In a first aspect, this utility model discloses a terminal bracket, including a base, a fracture-resistant component, and a flip frame. The fracture-resistant component includes a connecting part and a force-bearing part. The connecting part is connected to the base, and the force-bearing part is connected to the connecting part. The flip frame is rotatably connected to the force-bearing part so that the flip frame can rotate relative to the base.

[0006] Secondly, this utility model embodiment discloses a protective shell, including a shell and a terminal bracket as described in the first aspect, wherein the base is connected to the shell.

[0007] Compared with the prior art, the embodiments of this utility model have at least the following beneficial effects:

[0008] In this embodiment of the invention, the anti-fracture component is connected to the base via a connecting part, and the force-bearing part of the anti-fracture component is connected to the connecting part. The force-bearing part is rotatably connected to the flipping frame, allowing the flipping frame to rotate relative to the base and adjust the angle between them. When the flipping frame rotates to a preset angle relative to the base and continues to rotate, the force-bearing part elastically deforms relative to the connecting part as the flipping frame rotates, ensuring that the angle between the flipping frame and the base is greater than the preset angle. In other words, by providing the anti-fracture component, when the angle between the flipping frame and the base exceeds the preset angle, the elastic deformation of the anti-fracture component prevents deformation of the base and avoids breakage at the rotatable connection between the flipping frame and the base, thus extending the service life of the terminal bracket.

[0034] This utility model discloses a terminal bracket and a protective shell. When the flip frame rotates more than the maximum angle relative to the base, the anti-fracture component can undergo elastic deformation to prevent the base from deforming and to prevent breakage at the rotational connection between the flip frame and the base. The terminal bracket has a long service life.

[0035] Example 1

[0036] Please see Figures 1 to 3 This is a schematic diagram of the structure of a terminal bracket 100 provided in Embodiment 1 of the present utility model. The terminal bracket 100 includes a base 10, a fracture-resistant component 11, and a flip frame 13. The fracture-resistant component 11 includes a connecting part 111 and a force-bearing part 112. The connecting part 111 is connected to the base 10, and the force-bearing part 112 is connected to the connecting part 111. The flip frame 13 is rotatably connected to the force-bearing part 112 and can be relative to the base 10.

[0037] In this embodiment, the anti-fracture component 11 is connected to the base 10 via a connecting portion 111. The force-bearing portion 112 of the anti-fracture component 11 is located at the connecting portion 111, and is rotatably connected to the flipping frame 13. Thus, after the flipping frame 13 rotates relative to the base 10 to a preset angle α, it continues to rotate. At this time, the force-bearing portion 112 elastically deforms relative to the connecting portion 111 as the flipping frame 13 rotates, ensuring that the angle between the flipping frame 13 and the base 10 is greater than the preset angle α. That is, by providing the anti-fracture component 11, when the angle between the flipping frame 13 and the base 10 exceeds the preset angle α, the elastic deformation of the anti-fracture component 11 prevents deformation of the base 10 and avoids breakage at the rotatable connection between the flipping frame 13 and the base 10, resulting in a longer service life for the terminal bracket 100.

[0038] Among them, such as Figure 4 As shown, the preset angle α refers to the maximum included angle α between the tilting frame 13 and the base 10 that can be achieved by rotating the tilting frame 13 relative to the base 10 through the rotational connection between the tilting frame 13 and the force-bearing part 112. Figure 5 As shown, when the angle between the flipping frame 13 and the base 10 is greater than the preset angle α, the force-bearing part 112 undergoes elastic deformation relative to the connecting part 111.

[0039] Exemplarily, the flipping frame 13 is capable of rotating relative to the rotating connector 12 to at least switch to a first posture stacked on the base 10 (e.g., Figure 1 ) and the second posture tilted to the base 10 (such as Figure 2 Based on this, when the smart terminal is equipped with the terminal stand 100, the flip frame 13 is used to switch to the first posture, so that the terminal stand 100 is in a stored state, which makes it easy to carry and hold the smart terminal. When the flip frame 13 is used to switch to the second posture, the terminal stand 100 can support the smart terminal, so that the smart terminal can be placed at an angle on a flat surface such as a table.

[0040] Furthermore, under normal circumstances, when the flipping frame 13 switches to the second posture, the angle formed between the flipping frame 13 and the base 10 is less than or equal to the preset angle α. When the flipping frame 13 continues to rotate after rotating to the preset angle α, the angle formed between the flipping frame 13 and the base 10 is greater than the preset angle α. The flipping frame 13 drives the force-receiving part 112 to rotate relative to the base 10. At this time, the flipping frame 13 and the force-receiving part 112 remain relatively fixed (i.e., no relative rotation occurs), and the force-receiving part 112 moves accordingly and undergoes elastic deformation relative to the connecting part 111.

[0041] In some embodiments, the yield strength of the fracture-resistant component 11 is greater than that of the base 10, and the density of the fracture-resistant component 11 is greater than that of the base 10. Thus, when the angle between the tilting frame 13 and the base 10 changes, the main stress-bearing part is the fracture-resistant component 11. Especially when the angle between the tilting frame 13 and the base 10 is greater than a preset angle α, the deformation portion of the fracture-resistant component 11 experiences greater stress. Therefore, the fracture-resistant component 11 uses a material with higher yield strength and density, possessing higher structural strength and the ability to withstand greater forces, thus avoiding deformation, loss of elastic deformation capacity, or even fracture. The base 10, on the other hand, can use a material with lower yield strength and lower density to reduce the overall weight of the base 10.

[0042] In some embodiments, the force-bearing part 112 includes a first part 112a and a second part 112b, and the connecting part 111 includes two parts. Along the length direction of the fracture-resistant member 11, the two ends of the first part 112a are respectively connected to the two connecting parts 111. In this way, on the one hand, the connection between the fracture-resistant member 11 and the base 10 through the two connecting parts 111 is high and the connection is more secure, avoiding the situation where the fracture-resistant member 11 and the base 10 separate when the force-bearing part 112 is subjected to large forces. On the other hand, when the force-bearing part 112 undergoes elastic deformation under force, the force distribution on the fracture-resistant member 11 is more uniform, and the fracture-resistant member 11 can bear a larger force, thereby improving the quality of the terminal support 100 and avoiding the situation where the terminal support 100 is damaged due to excessive local stress.

[0043] As an optional implementation method, combined with Figure 6 and Figure 7As shown, the first part 112a is provided with two clearance parts 11a, which are spaced apart along the length of the first part 112a. The second part 112b includes a main body 121 and two first lugs 122. The main body 121 is connected to the side of the first part 112a facing the base 10. The two first lugs 122 are spaced apart from the main body 121 and protrude through the two clearance parts 11a to the side of the first part 112a away from the base 10. The flipping frame 13 is connected to the two first lugs 122 through a pivot 15 and can rotate relative to the two first lugs 122. In this way, on the one hand, the main body 121 is located on the side of the first part 112a facing the base 10, and the flipping frame 13 is connected by two first lugs 122. The flipping frame 13 can rotate relative to the base 10, and when the included angle between the flipping frame 13 and the base 10 is greater than α, the flipping frame 13 can drive the main body 121 to pry the first part 112a, so that the first part 112a undergoes elastic deformation relative to the connecting part 111. At the same time, by stacking the main body 121 and the first part 112a, the main body 121 acts as a reinforcing member to increase the structural strength of the fracture-resistant member 11 at the first part 112a, thereby enabling the fracture-resistant member 11 to withstand greater forces. On the other hand, by using two clearance parts 11a to pass through the two first lugs 122 to avoid the first lugs 122, structural reuse is achieved, which simplifies the structure of the fracture-resistant member 11 and reduces the design and manufacturing difficulty.

[0044] For example, such as Figure 3 and Figure 4 As shown, the terminal bracket 100 also includes a pivot 15 and a hinge 16. The pivot 15 is located on the second part 112b, and the hinge 16 is rotatably connected to the pivot 15. The flip frame 13 is connected to the hinge 16. Thus, by setting the pivot 15 on the second part 112b and connecting it to the pivot 15 via the hinge 16, and connecting the flip frame 13 to the hinge 16, the flip frame 13 can rotate relative to the second part 112b.

[0045] In some embodiments, such as Figure 4 and Figure 5As shown, the base 10 has a first surface 10a, and the first surface 10a is provided with a receiving groove 10b. The connecting part 111 is provided in the receiving groove 10b. When the flip frame 13 switches to the first posture, the force-bearing part 112 is located in the receiving groove 10b. When the flip frame 13 switches to the second posture, and the included angle formed between the flip frame 13 and the base 10 is equal to the preset angle α, the flip frame 13 abuts against the connection between the first surface 10a and the side wall of the receiving groove 10b. In this way, on the one hand, by accommodating the connecting part 111 and the force-bearing part 112 in the receiving groove 10b, the space occupied by the fracture-resistant part 11 can be reduced, which is beneficial to the thin and light design of the terminal bracket 100. On the other hand, by using the flip frame 13 to abut against the connection between the first surface 10a and the side wall of the receiving groove 10b, a limit can be achieved, and force feedback can be provided for user operation, reminding the user to rotate the flip frame 13 to the preset angle α.

[0046] As another alternative implementation method, such as Figure 8 As shown, the force-bearing part 112 includes a first part 112a and a second part 112b. The first part 112a and the second part 112b are arranged along the width direction of the fracture-resistant member 11. Along the length direction of the fracture-resistant member 11, the two ends of the first part 112a are respectively connected to two connecting parts 111, and the two ends of the second part 112b are respectively provided with second lugs 112c. The flipping frame 13 is rotatably connected to the two second lugs 112c. In this way, on the one hand, by using the two second lugs 112c to rotatably connect the flipping frame 13, the flipping frame 13 can rotate relative to the base 10. When the included angle between the flipping frame 13 and the base 10 is greater than α, the flipping frame 13 can drive the first part 112a and the second part 112b to tilt up through the second lugs 112c, so that the force-bearing part 112 as a whole undergoes elastic deformation relative to the connecting parts 111. On the other hand, by forming a second lug 112c in the fracture-resistant member 11, the rotational connection between the flip frame 13 and the force-bearing part 112 can be achieved without setting an additional rotational connection structure, which can reduce the overall thickness of the terminal bracket 100 and facilitate the application of the terminal bracket 100 to thinner products such as protective cases.

[0047] In some embodiments, the fracture-resistant member 11 has an arc-shaped structure, with the first part 112a located on the side of the arc-shaped structure closer to the circle, and the second part 112b located on the side of the arc-shaped structure away from the center. Thus, by providing the second lug 112c in the second part 112b, when the flipping frame 13 rotates, the force is transmitted sequentially along the second part 112b to the first part 112a and the connecting part 111. The force is distributed from the outside to the inside of the arc-shaped structure (i.e., gradually approaching the center), resulting in a more reasonable force distribution on the fracture-resistant member 11. This allows the fracture-resistant member 11 to withstand greater forces, improving the mass of the terminal support 100.

[0048] For example, along the width direction of the fracture-resistant member 11, the two ends of the second portion 112b along the length direction are spaced apart from the first portion 112a, so that a notch 11b is formed between the two ends of the second portion 112b and the first portion 112a. In this way, by setting the notch 11b, when manufacturing the fracture-resistant member 11, the notch 11b is used to avoid obstacles, which facilitates bending the second portion 112b to form the second lug 112c, reduces the manufacturing difficulty of the fracture-resistant member 11, and improves the production efficiency of the terminal bracket 100.

[0049] As another alternative implementation method, such as Figures 9 to 11 As shown, the force-bearing part 112 includes a first end 1121, a middle part 1122 and a second end 1123 arranged along the length direction of the anti-fracture member 11. The first end 1121 and the second end 1123 are respectively connected to two connecting parts 111.

[0050] exist Figure 9 and Figure 11 In the illustrated embodiment, along the thickness direction x of the fracture-resistant member 11, the intermediate portion 1122 is recessed relative to the first end 1121 and the second end 1123. Specifically, the surface of the intermediate portion 1122 facing the flip frame 13 is recessed relative to the surfaces of the first end 1121 and the second end 1123 facing the flip frame 13, so that the intermediate portion 1122 and the first end 1121 form a first step 11c, and the intermediate portion 1122 and the second end 1123 form a second step 11d. In this way, by making the intermediate portion 1122 as a whole sink relative to the first end 1121 and the second end 1123, and using the space (accommodating groove 10b) of the base 10 to accommodate the intermediate portion 1122, the overall thickness of the terminal bracket 100 can be reduced. Furthermore, the surface of the intermediate portion 1122 facing the flip frame 13 is provided with a protrusion 11e, and the surface of the protrusion 11e can be flush with the surfaces of the first end 1121 and / or the second end 1123 facing the flip frame 13. Thus, by providing protrusions 11e in the middle portion 1122, the structural strength of the middle portion 1122 can be improved, and the fracture-resistant member 11 can withstand greater forces. There can be one or more protrusions 11e. When there are multiple protrusions 11e, they are spaced apart along the length of the fracture-resistant member 11 to improve the structural strength at all locations in the middle portion 1122. Figure 9 In the embodiment shown, the protrusion 11e is formed by protruding directly from the surface of the middle portion 1122, while... Figure 11 In the illustrated embodiment, the protrusion 11e is formed by the lower surface of the middle portion 1122 being recessed, causing the upper surface of the middle portion 1122 to bulge. That is to say, the protrusion 11e can be implemented in various ways, and this application does not make a specific limitation, as long as it can achieve the same structure and function.

[0051] exist Figure 10 In the illustrated embodiment, the force-receiving portion 112 further includes a first recess 1124 and a second recess 1125. The first recess 1124 is located between the first end portion 1121 and the middle portion 1122, and the second recess 1125 is located between the second end portion 1123 and the middle portion 1122. The first recess 1124 is recessed relative to the first end portion 1121 and the middle portion 1122 to form a groove, which extends along the width direction of the force-receiving portion 112 and penetrates both sides of the width direction of the force-receiving portion 112. Similarly, the second recess 1125 is recessed relative to the second end portion 1123 and the middle portion 1122 to form a groove, which extends along the width direction of the force-receiving portion 112 and penetrates both sides of the width direction of the force-receiving portion 112. Through the above arrangement, the first recess 1124 and the second recess 1125 are equivalent to forming two reinforcing rib structures, which can effectively enhance the overall strength of the force-receiving portion 112.

[0052] Furthermore, the surfaces of the middle portion 1122 facing the flip frame 13, the first end 1121 facing the flip frame 13, and the second end 1123 facing the flip frame 13 are flush, so that the overall surface of the force-bearing portion 112 is relatively flat, which is more conducive to attaching decorative parts 14 to cover and decorate its surface. Correspondingly, the surfaces of the first recess 1124 and the second recess 1125 facing the flip frame 13 are both lower than the surface of the middle portion 1122 facing the flip frame 13.

[0053] Continue reading Figures 9-11In some embodiments, the anti-fracture component 11 further includes a third lug 113 and a fourth lug 114. The third lug 113 protrudes from the side of the first end 1121 in a direction away from the first end 1121, and the fourth lug 114 protrudes from the side of the second end 1123 in a direction away from the second end 1123. The flipping frame 13 is rotatably connected to the third lug 113 and the fourth lug 114 via a pivot 15. Thus, by providing the third lug 113 and the fourth lug 114 in the anti-fracture component 11, and connecting the flipping frame 13 using the third lug 113 and the fourth lug 114, the flipping frame 13 can rotate relative to the base 10. When the included angle between the flipping frame 13 and the base 10 is greater than α, the flipping frame 13 can cause the force-bearing part 112 to tilt upward through the third lug 113 and the fourth lug 114, so that the force-bearing part 112 as a whole undergoes elastic deformation relative to the connecting part 111. On the other hand, by forming the third lug 113 and the fourth lug 114 protruding on the sides of the force-bearing part 112 (i.e., the sides of the first end 1121 and the third end 1123), the height of the third lug 113 and the fourth lug 114 can be reduced along the thickness direction of the fracture-resistant member 11, thereby reducing the overall thickness of the fracture-resistant member 11, reducing the installation space, and making the structure more compact. At the same time, the third lug 113 and the fourth lug 114 are respectively provided on the sides of the first end 1121 and the third end 1123, and their positions on the force-bearing part 112 are reasonably distributed, which can make the force-bearing part 112 bear force evenly.

[0054] In some embodiments, see Figure 16 In this embodiment, the fracture-resistant member 11 further includes a third lug 113 and a fourth lug 114. The first recess 1124 has a first extension 1124a protruding from the first end 1121 along the width direction of the fracture-resistant member 11. The third lug 113 is connected to the side of the first extension 1124a away from the middle portion 1122, and the third lug 113 is spaced apart from the first end 1121. Similarly, the second recess 1125 has a second extension 1125a protruding from the second end 1123 along the width direction of the fracture-resistant member 11. The fourth lug 114 is connected to the side of the second extension 1125a away from the middle portion 1122, and the fourth lug 114 is spaced apart from the second end 1123. The flipping frame 13 is rotatably connected to the third lug 113 and the fourth lug 114 via a pivot 15, and the flipping frame 13 can rotate relative to the third lug 113 and the fourth lug 114. Compared to Figure 10In the illustrated embodiment, the connection positions of the third lug 113 and the fourth lug 114 are changed. Compared to the previous embodiment, in this embodiment, the various parts are more compact in the width direction of the anti-fracture member 11, which reduces the size of the anti-fracture member 11 in the width direction. This makes it easier to arrange the various components more reasonably within the limited space of the terminal bracket 100, and also helps to miniaturize the overall structure of the terminal bracket 100, so that it occupies less space on the protective shell after being combined with it. The third lug 113 is spaced apart from the first end 1121, and the fourth lug 114 is spaced apart from the second end 1123, which is more conducive to the bending and forming of the third lug 113 and the fourth lug 114.

[0055] In some embodiments, see Figure 17 In this embodiment, the anti-fracture member 11 also includes a third lug 113 and a fourth lug 114. The first recess 1124 has a first extension 1124a protruding from the middle portion 1122 along the width direction of the anti-fracture member 11. The third lug 113 is connected to the side of the first extension 1124a away from the first end 1121, and the third lug 113 is spaced apart from the middle portion 1122. The second recess 1125 has a second extension 1125a protruding from the middle portion 1122 along the width direction of the anti-fracture member 11. The fourth lug 114 is connected to the side of the second extension away from the second end 1123, and the fourth lug 114 is spaced apart from the middle portion 1122. The flipping frame 13 is connected to the third lug 113 and the fourth lug 114 via a pivot 15, and the flipping frame 13 can rotate relative to the third lug 113 and the fourth lug 114. Compared to Figure 16In the illustrated embodiment, the intermediate portion 1122 is adjusted, and the connection positions of the third lug 113 and the fourth lug 114 are changed. In contrast, in this embodiment, the dimension of the intermediate portion 1122 in the width direction of the fracture-resistant member 11 is reduced, resulting in a larger space between the third lug 113, the fourth lug 114, and the intermediate portion 1122. The flipping frame 13 is typically rotatably connected to the third lug 113 and the fourth lug 114 via a pivot 15. As the terminal support 100, the flipping frame 13 needs a certain amount of damping during rotation to ensure that it can remain at the rotated angle for support, and the damping force needs to reach a certain value to ensure that the flipping frame 13 does not sway during support. Damping force is typically provided by the friction between the rotating shaft 15 and the bushing fitted on the rotating shaft 15. When the diameter of the rotating shaft 15 is different, the contact area between the rotating shaft 15 and the bushing is also different, and the friction force will also be different. It can be understood that the larger the diameter of the rotating shaft 15, the greater the friction force between the rotating shaft 15 and the bushing, and the greater the damping force it can provide. Therefore, in this embodiment, the larger space formed between the third lug 113, the fourth lug 114 and the middle portion 1122 can ensure that the terminal bracket 100 uses a rotating shaft 15 with a larger diameter, and there will be no interference between the rotating shaft 15 and the middle portion 1122. Furthermore, the width dimension of the anti-fracture member 11 will not increase as a result. At the same time, the larger diameter of the rotating shaft 15 can increase the damping force when the tilting frame 13 rotates, making the support of the tilting frame 13 more stable and reliable.

[0056] Furthermore, the third lug 113 includes a first protrusion 113a and a first shaft hole 113b. The first protrusion 113a is connected to the first extension 1124a, and the first shaft hole 113b is provided with a first shaft hole. The fourth lug 114 includes a second protrusion 114a and a second shaft hole 114b. The second protrusion 114a is connected to the second extension 1125a, and the second shaft hole 114b is provided with a second shaft hole. The flipping frame 13 is connected to the first shaft hole 113b and the second shaft hole 114b via a rotating shaft 15. Both ends of the rotating shaft 15 are respectively inserted into the first shaft hole and the second shaft hole, and both ends of the rotating shaft 15 are fixedly connected to the first shaft hole 113b and the second shaft hole 114b, respectively.

[0057] In some embodiments, continue reading Figure 18 and Figure 19The base 10 has a receiving groove 10b and a first mounting portion 10c and a second mounting portion 10d located on both sides of the receiving groove 10b. Two connecting portions 111 are respectively connected to the first mounting portion 10c and the second mounting portion 10d. The third lug 113, the fourth lug 114, and the middle portion 1122 are all located within the receiving groove 10b. In this embodiment, the receiving groove 10b is a through-hole structure that penetrates the base 10 along its thickness direction. The through-hole structure provides more space to accommodate the fracture-resistant component 11. In other embodiments, the receiving groove 10b may not be a through-hole structure. For example, the receiving groove 10b may have a bottom wall that separates the fracture-resistant component 11 from the protective shell on the other side of the base 10 to prevent friction between them. By providing a receiving groove 10b on the base 10 to accommodate the fracture-resistant component 11, the overall thickness of the terminal bracket 100 can be effectively reduced, which is more conducive to its lightweight design. Furthermore, the sidewall of the receiving groove 10b is also provided with a filling part 10e, which extends toward the direction of the flipping frame 13 and extends into the space between the third protruding ear 113 and the fourth protruding ear 114 to fill the space formed between the third protruding ear 113, the fourth protruding ear 114 and the middle part 1122. As mentioned in the above embodiment, by forming a larger space between the third protruding ear 113, the fourth protruding ear 114 and the middle part 1122, it can be ensured that the terminal bracket 100 can use a larger diameter pivot 15. However, due to structural and space limitations, the pivot 15 only occupies a part of the space. That is to say, there is still a part of the space between the middle part 1122 and the pivot 15. When the decorative part 14 is attached to the surface of the fracture-resistant part 11, the existence of this part of the space may cause the decorative part 14 to be uneven after it is attached. That is, at the position corresponding to this space, the decorative part 14 will collapse, resulting in an uneven surface and affecting the appearance of the product. Therefore, by providing a filling portion 10e, which fills the space, the decorative element 14 is supported. Specifically, the filling portion 10e is formed by protruding from the side wall of the receiving groove 10b, and the portion extending into the space can be thickened so that the upper surface of the filling portion 10e is approximately flush with the upper surface of the middle portion 1122. It should be noted that the filling in this embodiment does not mean that the filling portion 10e completely fills the space, but rather that the filling portion 10e occupies most of the space. There can be a certain gap between the filling portion 10e and the middle portion 1122, the first protrusion 113a, the second protrusion 114a, and the bushing fitted on the rotating shaft 15 to prevent interference caused by them being tightly pressed together.

[0058] In some embodiments, combined with Figure 12As shown, the terminal support 100 also includes a decorative element 14. The decorative element 14 is disposed on the surface of the protrusion 11e facing away from the base 10 and the surface of the connecting portion 111 facing away from the base 10, and the decorative element 14 is provided to cover the anti-fracture member 11. In this way, by providing the decorative element 14 on the surface of the protrusion 11e facing away from the base 10 and the surface of the connecting portion 111 facing away from the base 10, the anti-fracture member 11 can be protected by the decorative element 14, and the appearance integrity of the terminal support 100 in the second posture can be maintained. Furthermore, by using the protrusion 11e to protrude away from the base 10 along the thickness direction x of the anti-fracture member 11, and the surface of the protrusion 11e facing away from the base 10 being flush with the surface of the connecting portion 111 facing away from the base 10, the assembly difficulty of the decorative element 14 and the anti-fracture member 11 is reduced. In other embodiments, the decorative element 14 can also be disposed on the surface of the anti-fracture element 11 away from the flipping frame 13. For example, when the receiving groove 10b provided on the base 10 is a through hole structure, the decorative element 14 can cover the opening of the through hole facing the protective shell. This can ensure that when a material such as lubricating oil is provided between the base 10 and the protective shell to increase the smoothness of rotation between the base 10 and the protective shell, the decorative element 14 covering the opening of the through hole can effectively prevent the lubricating oil from overflowing from the through hole onto the anti-fracture element 11 and the flipping frame 13.

[0059] Optionally, the protrusion 11e may include one or more, which can be selected according to the actual situation, and this embodiment does not make a specific limitation. When the protrusion 11e includes multiple protrusions, the multiple protrusions 11e are arranged at intervals along the length direction of the fracture-resistant member 11.

[0060] This embodiment provides various types of fracture-resistant components 11, forming the force-bearing part 112 and the connecting part 111 in different ways. Different types of fracture-resistant components 11 can be selected for the terminal bracket 100 according to the actual situation to meet different usage requirements.

[0061] For example, such as Figure 4 As shown, the thickness of the fracture-resistant component 11 is t, where 0.3mm ≤ t ≤ 1mm. If the thickness t of the fracture-resistant component 11 is less than 0.3mm, the thickness of the fracture-resistant component 11 is relatively small, resulting in lower structural strength. After the force-bearing part 112 undergoes elastic deformation relative to the fixed seat, it is prone to elastic failure and cannot return to its initial state. If the thickness t of the fracture-resistant component 11 is greater than 1mm, the thickness t of the fracture-resistant component 11 is relatively large while still meeting the deformation requirements, leading to a larger overall thickness of the terminal bracket 100, which is not conducive to the lightweight design of the terminal bracket 100. Therefore, the thickness t of the fracture-resistant component 11 can be 0.3mm ≤ t ≤ 1mm, resulting in higher structural strength. This avoids the situation where the force-bearing part 112 fails to return to its initial state after elastic deformation relative to the fixed seat, and the overall thickness of the terminal bracket 100 is smaller, which is beneficial to the lightweight design of the terminal bracket 100.

[0062] Furthermore, the thickness t of the fracture-resistant component 11 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc., and this embodiment does not specifically limit it.

[0063] In some embodiments, combined with Figure 8 As shown, the thickness of the fracture-resistant component 11 is t. The connecting part 111 is riveted to the base 10. The distance from the riveted joint of the connecting part 111 and the base 10 to the elastic connection between the force-bearing part 112 and the connecting part 111 is L, where 2t ≤ L ≤ 10t. If the distance L from the riveted joint of the connecting part 111 and the base 10 to the elastic connection between the force-bearing part 112 and the connecting part 111 is less than 2t, then the lever arm of the force-bearing part 112 when deforming relative to the fixed seat is small, making deformation difficult. If the distance L from the riveted joint of the connecting part 111 and the base 10 to the elastic connection between the force-bearing part 112 and the connecting part 111 is greater than 10t, then under the given condition, the size of the connecting part 111 is large, occupying a large space, which is not conducive to the miniaturization design of the terminal bracket 100. Therefore, the distance L from the riveting point between the connecting part 111 and the base 10 to the elastic connection point between the force-bearing part 112 and the connecting part 111 can be 2t≤L≤10t, which satisfies the lever arm required for the force-bearing part 112 to deform relative to the fixed seat. In addition, the connecting part 111 is small in size and occupies less space, which is conducive to the miniaturization design of the terminal bracket 100.

[0064] Furthermore, the distance L from the riveting point between the connecting part 111 and the base 10 to the elastic connection point between the force-bearing part 112 and the connecting part 111 can be 2t, 3t, 4t, 5t, 6t, 7t, 8t, 9t, 10t, etc., and this embodiment does not make a specific limitation on this.

[0065] For example, the width of the force-bearing part 112 is d1, where d1 ≥ 4t. If the width d1 of the force-bearing part 112 is < 4t, the structural strength of the force-bearing part 112 is low. When the angle formed between the tilting frame 13 and the base 10 is greater than α, the force-bearing part 112 itself is easily deformed by force and thus damaged, and it cannot undergo elastic deformation relative to the fixed seat. Therefore, the width d1 of the force-bearing part 112 can be d1 > 4t. The structural strength of the force-bearing part 112 is high, and when the angle formed between the tilting frame 13 and the base 10 is greater than α, the force-bearing part 112 itself will not deform due to force and thus will not be damaged, and it can undergo elastic deformation relative to the fixed seat.

[0066] Furthermore, the width d1 of the force-bearing part 112 can be 4t, 4.5t, 5t, 5.5t, 6t, 6.5t, 7t, etc., and this embodiment does not specifically limit it.

[0067] For example, the width of the connecting part 111 is d2, where t ≤ d2 ≤ 5t. If the width d2 of the connecting part 111 is less than t, then the width d2 of the connecting part 111 is small, and the structural strength of the connecting part 111 is low. When the angle formed by the flipping frame 13 and the base 10 is greater than α, the force-bearing part 112 undergoes elastic deformation relative to the connecting part 111. At this time, the connecting part 111 is easily deformed and damaged. If the width d2 of the connecting part 111 is greater than 5t, then the width d2 of the connecting part 111 is large while still meeting the required structural strength, occupying a large space, which is not conducive to the miniaturization design of the terminal bracket 100. Therefore, the width d2 of the connecting part 111 can be t ≤ d2 ≤ 5t. While ensuring that the connecting part 111 meets the required structural strength, the width d2 of the connecting part 111 is small, occupying less space, which is beneficial to the miniaturization design of the terminal bracket 100.

[0068] Furthermore, the width d2 of the connecting part 111 can be t, 1.5t, 2t, 2.5t, 3t, 3.5t, 4t, 4.5t, 5t, etc., and this embodiment does not specifically limit it.

[0069] This utility model provides a terminal bracket 100, which is connected to a base 10 via a connecting portion 111 of an anti-fracture member 11. A force-bearing portion 112 of the anti-fracture member 11 is located at the connecting portion 111, and is rotatably connected to a flip frame 13. Thus, after the flip frame 13 rotates relative to the base 10 to a preset angle α, it continues to rotate. At this time, the force-bearing portion 112 elastically deforms relative to the connecting portion 111 as the flip frame 13 rotates, ensuring that the angle between the flip frame 13 and the base 10 is greater than the preset angle α. In other words, by providing the anti-fracture member 11, when the angle between the flip frame 13 and the base 10 exceeds the preset angle α, the elastic deformation of the anti-fracture member 11 prevents deformation of the base 10 and avoids breakage at the rotatable connection between the flip frame 13 and the base 10, resulting in a longer service life for the terminal bracket 100.
