Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment accessories, in particular to a rotating shaft structure, an electronic equipment bracket and an electronic equipment protective shell. Background Art

[0002] With the development of electronic devices, the use environments of electronic devices such as mobile phones are also increasing. For example, when watching videos on a mobile phone, using an electronic device stand to support it so that it can be raised and placed on a flat surface will undoubtedly improve the user experience. Currently, most electronic device stands on the market connect the stand body and the electronic device protective case through a hinge shaft structure, so that the stand body can rotate relative to the electronic device protective case, so that the stand body can be stored in the electronic device protective case when the electronic device stand is not needed.

[0003] For example, the hinge shaft structure includes a first connecting member, a second connecting member and a rotating shaft, the first connecting member is provided with a first connecting portion (i.e., a rotating shaft connecting portion), the rotating shaft is inserted into the shaft hole of the first connecting portion and is rotatably connected to the first connecting portion by interference fit, and both ends of the rotating shaft are clamped on the fixing portion of the second connecting member, so that when the first connecting member rotates relative to the second connecting member, the rotating shaft will rotate relative to the first connecting member, and the rotating shaft is fixed relative to the second connecting member. In order to allow the first connecting member to arbitrarily hover relative to the second connecting member during the rotation process and maintain this state, in the length direction of the rotating shaft, the length of the first connecting portion is set to be longer than the length of the fixing portion, so as to enhance the friction between the rotating shaft and the first connecting portion, thereby enhancing the ability of the first connecting member to hover relative to the second connecting member.

[0004] However, since the upper hinge shaft structure used in the electronic device bracket is relatively small, when the length of the hinge structure in the shaft length direction does not change, the length of the fixing portion is shortened, resulting in a decrease in the ability of the fixing portion to hold the shaft to fix the shaft. As a result, after the first connecting member rotates relative to the shaft for many times, the shaft is easily loosened from the fixing portion of the second connecting member, thereby destroying the effect of the first connecting member freely hovering when rotating relative to the second connecting member; or, in order to further improve the ability of the fixing portion of the second connecting member to fix the shaft, the shaft is fixed to the fixing portion of the second connecting member by laser welding, but this fixing method is more cumbersome.

[0037] [First embodiment]

[0038] See also Figure 1 The first embodiment of the utility model provides a rotating shaft structure 100, which includes, for example, a first connecting member 10, a rotating shaft 20 and a second connecting member 30. The first connecting member 10 includes, for example, a first connecting portion 11, and the rotating shaft 20 includes, for example, a first rotating shaft end 21 and a second rotating shaft end 22 that are arranged opposite to each other, and a second connecting portion 23 located between the first rotating shaft end 21 and the second rotating shaft end 22. The first connecting portion 11 is sleeved on the second connecting portion 23 and can rotate relative to the second connecting portion 23, so that the first connecting member 10 and the rotating shaft 20 are connected in a rotational connection by interference fit. The second connecting member 30 includes, for example, a first fixing portion 311 and a second fixing portion 321 that are arranged at intervals, and the first fixing portion 311 and the second fixing portion 321 are respectively assembled to the first rotating shaft end 21 and the second rotating shaft end 22, and the first connecting member 10 and the second connecting member 30 are connected in rotation through the rotating shaft 20. The first fixing portion 311 and the second fixing portion 321 are respectively assembled to the first end 21 and the second end 22 of the shaft, for example, the first end 21 of the shaft is clamped into the axial hole of the first fixing portion 311, and the second end 22 of the shaft is clamped into the axial hole of the second fixing portion 321.

[0039] The first connecting part 11 is sleeved on the second connecting part 22 to enable the first connecting member 10 to be rotatably connected with the rotating shaft 20 by interference fit, and the first end 21 of the rotating shaft and the second end 22 of the rotating shaft are respectively clamped and fixed on the fixing part of the second connecting member 30, so that when the first connecting member 10 rotates relative to the second connecting member 30, the rotating shaft 20 will rotate relative to the first connecting member 10, while the rotating shaft 20 is fixed relative to the second connecting member 30.

[0040] Specifically, see Figure 1 and Figure 2The first end 21 of the rotating shaft is provided with a first limiting section 211, the first limiting section 211 is provided with a first limiting portion 2111, and the first fixing portion 311 is provided with a first anti-rotation portion 312 corresponding to the first limiting portion 2111. Specifically, the first limiting section 211 is inserted into the shaft hole of the first fixing portion 311, and the first limiting portion 2111 is engaged with the first anti-rotation portion 312 to limit the rotation of the rotating shaft 20 relative to the first fixing portion 311. For example, the first limiting portion 2111 is a section, the cross section of the first limiting segment 211 is non-circular, the first anti-rotation portion 312 is a section matched with the first limiting portion 2111, and the cross section of the shaft hole of the first fixing portion 311 is also non-circular, so that the shaft hole of the first fixing portion 311 matches the first limiting segment 211, and then when the first limiting segment 211 is inserted into the shaft hole of the first fixing portion 311, the first limiting portion 2111 is engaged with the first anti-rotation portion 312, thereby limiting the rotation of the rotating shaft 20 relative to the first fixing portion 311. For example, the non-circular shape mentioned here is, for example, a "D" shape.

[0041] The first embodiment of the utility model provides a rotating shaft structure 100, in which a limiting portion 2111 is provided on the first limiting section 211 and a stop portion 312 is provided on the first fixing portion 311. The limiting portion 2111 and the stop portion 312 are engaged with each other to limit the mutual rotation between the rotating shaft 20 and the first fixing portion 311, thereby improving the ability of the first fixing portion 311 to fix the rotating shaft 20. When the rotating shaft 20 rotates relative to the first connecting member 10, the rotating shaft 20 will not loosen from the first fixing portion 311, thereby achieving the improvement of the fixing ability of the fixing portion of the second connecting member 30 to the rotating shaft 20 without reducing the friction force provided by the first connecting member 11 to the rotating shaft 20 and without the need to perform laser welding on the fixing portion and the rotating shaft 20.

[0042] The hinge structure 100 provided in the first embodiment of the utility model can be applied to electronic equipment accessories, and specifically applied to electronic equipment brackets as the hinge structure of the bracket. For example, the bracket body is fixedly connected to the first connecting member 10, and the second connecting member 30 is fixedly connected to the electronic equipment protective shell, so that when the electronic equipment bracket needs to be used, the bracket body can be rotated relative to the electronic equipment protective shell to support the electronic equipment, and when the bracket is not needed, the bracket body can be rotated to be stored in the electronic equipment protective shell for easy carrying by users.

[0043] Further, see Figure 1, the cross-sectional area of ​​the first end 21 of the shaft is smaller than the cross-sectional area of ​​the shaft 20 away from the first end 21 of the shaft, so that the cross-sectional area of ​​the second end 23 of the shaft is larger than the cross-sectional area of ​​the first end 21 of the shaft, so that it is easy to install. Specifically, when the shaft 20 is assembled with the first connecting member 10 and the second connecting member 30, the first end 21 of the shaft 20 is inserted from the second fixing portion 321 through the first connecting portion 11 to the first fixing portion 311. When the cross-sectional area of ​​the first end 21 of the shaft is small, the shaft 20 can be quickly installed on the first connecting member 10 and the second connecting member 30, and at the same time, the part of the cross-sectional area of ​​the shaft 20 that is larger than the cross-sectional area of ​​the first end 21 of the shaft can be limited from passing through the first fixing portion 311.

[0044] As mentioned above, the cross-sectional area of ​​the shaft hole of the first fixing part 311 is smaller than the cross-sectional area of ​​the shaft hole of the second fixing part 321. The shaft hole of the first fixing part 311 matches the first end 21 of the rotating shaft, and the shaft hole of the second fixing part 321 matches the second end 22 of the rotating shaft, so the corresponding cross-sectional areas also match them. This can further facilitate the assembly of the rotating shaft 20 on the first connecting member 10 and the second connecting member 30, and at the same time, based on the smaller area of ​​the shaft hole of the first fixing part 311, it can prevent the rotating shaft 20 from accidentally passing through the first fixing part 311.

[0045] In addition, see Figure 3, for example, a second limiting section 221 is provided on the second end 22 of the rotating shaft, that is, the second end 22 of the rotating shaft is similar in structure to the first end 21 of the rotating shaft. Specifically, a second limiting portion 2211 is provided on the second limiting section 221, and a second anti-rotation portion 322 is provided on the second fixing portion 321 corresponding to the second limiting portion 2211. Specifically, the second limiting section 221 is inserted into the shaft hole of the second fixing portion 321, and the second limiting portion 2211 is engaged with the second anti-rotation portion 322 to limit the rotation of the rotating shaft 20 relative to the second fixing portion 321. For example, the second limiting portion 2211 is a section, the cross section of the second limiting segment 221 is non-circular, the second anti-rotation portion 322 is a section matched with the second limiting portion 2211, and the cross section of the shaft hole of the second fixing portion 321 is also non-circular, so that the shaft hole of the second fixing portion 321 matches the second limiting segment 221, and then when the second limiting segment 221 is inserted into the shaft hole of the second fixing portion 321, the second limiting portion 2211 is engaged with the second anti-rotation portion 322, thereby limiting the rotation of the rotating shaft 20 relative to the second fixing portion 321. For example, the non-circular shape mentioned here is, for example, a "D" shape. Providing a second limiting portion 2211 on the second limiting section 221 and a second anti-rotation portion 322 on the second fixing portion 321, for example, has similar effects as providing a first limiting portion 2111 on the first limiting section 211 and a first anti-rotation portion 312 on the first fixing portion 311, and no further elaboration is given here. Providing limiting portions on both the first limiting section 211 and the second limiting section 221, and anti-rotation portions that cooperate with the limiting portions on both the first fixing portion 311 and the second fixing portion 321, can further enhance the ability of the first fixing portion 311 and the second fixing portion 321 to fix the rotating shaft 20, thereby achieving double reinforcement.

[0046] See also Figure 3 and Figure 4, the first connection part 11 is provided with a first limiting plane 111, and the second connection part 23 is provided with a second limiting plane 231 matched with the first limiting plane 111. For example, the first limiting plane 111 and the second limiting plane 231 mentioned here are, for example, a section. The damping force of the first connection part 11 on the second connection part 23 is increased by providing the first limiting plane 111 and the second limiting plane 231. For example, when the first connecting member 10 rotates relative to the second connecting member 30, the first limiting plane 111 and the second limiting surface 231 are misaligned, so that the damping force of the first connecting part 11 on the rotating shaft 20 is enhanced, so that the first connecting member 10 can hover at any position relative to the second connecting member 30 during the rotation process; and when the first connecting member 10 needs to be reset, when the first limiting plane 111 is almost flat against the second limiting surface 231, the first connecting member 10 will automatically rebound, so that the first limiting surface 111 and the second limiting surface 231 fit each other, thereby facilitating the reset between the first connecting member 10 and the second connecting member 30.

[0047] In one embodiment, see Figure 5 and Figure 6 , the first end 21 of the rotating shaft is also provided with a first reinforcement section 212, wherein a first groove 213 is formed between the first reinforcement section 212 and the first limiting section 211, the first fixing portion 311 includes a first locking portion 313, the first anti-rotation portion 312 is provided on the first locking portion 313, and the first anti-rotation portion 312 is clamped in the first groove 213. By providing the first reinforcement section 212, the first reinforcement section 212 and the first limiting section 211 are used to clamp the first locking portion 313 together, thereby further improving the stability of the fixed connection between the rotating shaft 20 and the first fixing portion 311. Optionally, the second end 22 of the rotating shaft is also provided with a second reinforcement section (not shown in the figure), that is, the second end 22 of the rotating shaft is similar in structure to the first end 21 of the rotating shaft. Specifically, a second groove (not shown in the figure) is formed between the second reinforcement section and the second limiting section, the second fixing portion 321 includes a second locking portion (not shown in the figure), the second anti-rotation portion 312 is arranged on the second locking portion, and the second locking portion is clamped in the second groove. The second reinforcement section has similar effects to the first reinforcement section, and will not be described in detail here. The simultaneous arrangement of the first reinforcement section and the second reinforcement section can further enhance the ability of the first fixing portion 311 and the second fixing portion 321 to fix the rotating shaft 20, thereby achieving double reinforcement.

[0048] Further, see Figure 5, the cross-sectional area of ​​the first end 21 of the shaft is smaller than the cross-sectional area of ​​the second connection portion 23, and the cross-sectional area of ​​the second connection portion 23 is smaller than or equal to the cross-sectional area of ​​the second end 22 of the shaft. By setting the shaft 20 as a stepped shaft with different cross-sectional areas, it is convenient for the small end (the first end 21 of the shaft) to quickly penetrate from the second fixing portion 321. At the same time, when the shaft 20 is fixed to the first fixing portion 311, the shaft 20 can no longer continue to extend from the first fixing portion 311, thereby preventing the shaft 20 from being separated from the first connecting member 10 and the second connecting member 30.

[0049] In a specific embodiment, see also Figure 3 , the second connecting member 30 includes a lifting portion 33 and an external connecting portion 34, the lifting portion 33 connects the first fixing portion 311 and the second fixing portion 321, and is connected to the external connecting portion 34, the external connecting portion 34 is used to connect to an external device, wherein a fixed angle is formed between the lifting portion 33 and the external connecting portion 34. For example, it can be understood here that by setting the lifting portion 33, there is a relative height between the first fixing portion 311 and the external connecting portion 34, and there is also a relative height between the second fixing portion 321 and the external connecting portion 34. The angle mentioned here can be set according to actual conditions, and this application is not limited to this. By setting the lifting portion 33 to lift the first fixing portion 311 and the second fixing portion 321 relative to the external connecting portion 34, the first connecting member 10 and the external connecting portion 34 are relatively lifted. When the first connecting member 10 is connected to the bracket body, and the external connecting portion 34 is connected to the mobile terminal protective shell, the effect of lifting the bracket body relative to the mobile terminal protective shell can be achieved.

[0050] In addition, see Figure 7 The second connecting member 30 further includes a first anti-slipping portion 314 and a second anti-slipping portion 324, wherein the first anti-slipping portion 314 is connected to the first fixing portion 311, and the shaft hole of the first anti-slipping portion 314 is spaced apart from the shaft hole of the first fixing portion 311 and arranged oppositely, and the first anti-slipping portion 314 and the first fixing portion 311 are simultaneously assembled to the first end 21 of the rotating shaft; the second anti-slipping portion 324 is connected to the second fixing portion 321, and the shaft hole of the second anti-slipping portion 324 is spaced apart from the shaft hole of the second fixing portion 321 and arranged oppositely, and the second anti-slipping portion 324 and the second fixing portion 321 are simultaneously assembled to the second end 22 of the rotating shaft. The anti-slipping portion is arranged to achieve double fixation in cooperation with the fixing portion, thereby further improving the fixing effect of the second connecting member 30 on the rotating shaft 20.

[0051] The first fixing portion 311 and the first anti-slipping portion 314 are, for example, an integrally formed structure, and / or the second fixing portion 321 and the second anti-slipping portion 324 are an integrally formed structure. Specifically, the above-mentioned integrally formed structure is, for example, an elastic integrally formed structure. Since the rotating shaft 20 is clamped on the first anti-slipping portion 314 and the first fixing portion 311, the first anti-slipping portion 311 expands outward relative to the first fixing portion 313, resulting in a tendency for the axial holes of the first anti-slipping portion 314 and the first fixing portion 311 to deviate from the center line, thereby enhancing the ability of the first anti-slipping portion 314 and the first fixing portion 311 to clamp the first end 21 of the rotating shaft. The effects of the second anti-slipping portion 324 and the second fixing portion 321 are similar to those of the first anti-slipping portion 314 and the first fixing portion 311, and will not be elaborated here.

[0052] In a preferred embodiment, see also Figure 7 The second connecting member 30, for example, includes a first sub-connecting member 31 and a second sub-connecting member 32 that are independent of each other, the first anti-detachment portion 314 and the first fixing portion 311 are arranged on the first sub-connecting member 31, and the second anti-detachment portion 324 and the second fixing portion 321 are arranged on the second sub-connecting member 32. This arrangement is to facilitate the assembly of the first sub-connecting member 31 and the second sub-connecting member 32 at the two ends of the rotating shaft 20. If the first sub-connecting member 31 and the second sub-connecting member 32 are an integrated structure, when the rotating shaft 20 passes through the four shaft holes of the second fixing portion 321, the second anti-detachment portion 324, the first anti-detachment portion 314 and the first fixing portion 311 in sequence for assembly, it is easy to cause the shaft holes to be misaligned, resulting in the occurrence of misalignment of the shaft holes. Therefore, the first sub-connecting member 31 and the second sub-connecting member 32 are arranged as two independent components to be assembled at the two ends of the rotating shaft 20.

[0053] To summarize, the first embodiment of the utility model provides a rotating shaft structure, in which the cross-sections of the first limiting section and the shaft hole of the first fixing part matched therewith are both non-circular, and the non-circular cross-section is utilized to limit the mutual rotation between the rotating shaft and the first fixing part, thereby improving the ability of the first fixing part to fix the rotating shaft.
