[0029] In order to enable those skilled in the art to better understand the implementation scheme of the present utility model, the technical scheme in the implementation scheme of the present utility model will be clearly and completely described below in conjunction with the drawings in the implementation scheme of the present utility model. Obviously, the described implementation scheme is only a part of the implementation scheme of the present utility model, not all of the implementation schemes. Based on the implementation scheme in the implementation scheme of the present utility model, all other implementation schemes obtained by those skilled in the art without making creative work are within the scope of protection of the implementation scheme of the present utility model.
[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0031] See also Figure 1 and Figure 2The embodiment of the utility model provides a bracket 100, which includes a support member 11, a curling connector 13, a rotating shaft 14, and a curling protection member 121. The rotating shaft 14 is assembled on the curling connector 13, and the support member 11 and the curling connector 13 are rotatably connected through the rotating shaft 14. The curling protection member 121 is sleeved on the curling connector 13 and fixed relative to the curling connector 13. Among them, the curling protection member 121 can be a sleeve structure, etc., and can be specifically set according to actual conditions.
[0032] In this way, the curling protection part 121 can limit the outward deformation of the curling connector 13, so that the curling connector 13 can be deformed within a certain range, thereby helping to reduce the situation where the curling connector 13 is damaged due to excessive deformation. The curling protection part 121 also helps to reduce the situation where foreign impurities such as dust and particles enter the curling connector 13 and the rotating shaft 14, thereby providing certain protection for the curling connector 13 and the rotating shaft 14.
[0033] See also Figures 3 to 5 In some embodiments, the curling protection member 121 includes a accommodating space 1214 and a limiting space 1215 , the curling connector 13 includes a curling portion 132 and a limiting portion 133 , and the curling portion 132 is disposed in the accommodating space 1214 .
[0034] In this way, the curling protection member 121 can provide a space for accommodating the rotating shaft 14 and the curling connector 13, which helps to reduce the exposure of the curling connector 13 from the curling protection member 121 and helps to reduce the damage of the curling connector 13.
[0035] In some embodiments, the limiting portion 133 is disposed in the limiting space 1215 to fix the curled connector 13 relative to the curled protective member 121. This helps to ensure the stability of the curled protective member 121 sleeved on the curled connector 13, helps to reduce the situation where the curled protective member 121 is loosened from the curled connector 13, thereby helping to ensure the deformation limiting effect of the curled protective member 121 on the curled connector 13, and also helps to improve the compactness of the structure of the bracket 100.
[0036] When the rotating shaft 14 rotates, the rolled connector 13 can be fixed in the rolled protective member 121, which helps to reduce the situation where the rolled connector 13 and the rotating shaft 14 rotate synchronously, so that the rotating shaft 14 can rotate relative to the rolled connector 13. The rolled connector 13 can provide a force to stop the rotating shaft 14 from rotating, which helps to ensure the limiting effect of the rolled connector 13 on the rotating shaft 14.
[0037] In addition, the limiting portion 133 can also locate the installation position of the curling protection member 121, which helps to improve the accuracy of the installation position of the curling protection member 121, thereby helping to improve the efficiency of assembling the curling protection member 121 to the curling connector 13.
[0038] Exemplarily, when the curling protection piece 121 needs to be assembled on the curling connector 13, the installation position of the limiting space 1215 can be located by the limiting portion 133, and the installation of the curling protection piece 121 is completed by aligning the limiting space 1215 with the limiting portion 133 and limiting the limiting portion 133 in the limiting space 1215, thereby improving the installation efficiency of the curling protection piece 121.
[0039] In some embodiments, the limiting portion 133 is disposed at one end of the rolled portion 132 , so that the rolled connector 13 can be accommodated in the limiting space 1215 through the limiting portion 133 at the end.
[0040] In some embodiments, the limiting portion 133 may also include two, such as Figure 6 As shown, the two limiting portions 133 are respectively disposed at two opposite ends of the curled portion 132 , thereby helping to improve the stability of the limiting portion 133 accommodated in the limiting space 1215 .
[0041] Exemplarily, the limiting portion 133 may include a first limiting body 1331 and a second limiting body 1332 , which are respectively located on both sides of the length direction of the rolled portion 132 , and are symmetrically divided with respect to the rolled portion 132 .
[0042] In this way, the first limiting body 1331 and the second limiting body 1332 help to improve the stability of the limiting portion 133 contained in the limiting space 1215, help to improve the stability of the curling protection member 121 assembled on the curling connector 13, and also help to balance the weight of the structures on both sides of the curling connector 13, so that the two sides of the curling connector 13 can provide a more balanced force for the rotating shaft 14.
[0043] In some embodiments, the accommodating space 1214 is connected to the limiting space 1215. This facilitates the manufacture of the curling protection member 121 and makes the curling portion 132 and the accommodating space 1214 that match the accommodating space 1214 and the limiting space 1215 more compact.
[0044] See also Figure 6 In some embodiments, the curled portion 132 and the limiting portion 133 are spaced apart from each other, and a deformation space 134 is formed therebetween.
[0045] In this way, the deformation space 134 can assist the deformation of the rolled portion 132, which helps the deformation and deformation reset of the rolled portion 132, and helps reduce the situation where the rolled portion 132 is damaged by being squeezed for a long time. When the rotating shaft 14 rotates relative to the rolled connecting member 13, the deformation space 134 allows the rolled portion 132 at the position of the deformation space 134 to deform to both sides, thereby helping to reduce the contact friction between the rotating shaft 14 and the rolled portion 132, helping to reduce the situation where the rolled portion 132 fails due to excessive friction between the rotating shaft 14 and the rolled portion 132, thereby helping to extend the service life of the rolled connecting member 13.
[0046] In some embodiments, the deformation space 134 may include a first space 1341 and a second space 1342 , the first space 1341 and the second space 1342 are respectively located on both sides of the length direction of the rolled portion 132 , and the first space 1341 and the second space 1342 are symmetrically divided with respect to the rolled portion 132 .
[0047] For example, the first space 1341 may be located between the first position limiting body 1331 and the rolled portion 132, and the second space 1342 may be located between the second position limiting body 1332 and the rolled portion 132. In this way, the first space 1341 and the second space 1342 help the rolled portion 132 to deform better, help balance the stress on the inner side of the rolled portion 132 due to deformation, thereby better extending the service life of the rolled portion 132, and also help balance the stress on both sides of the rolled portion 132 in the length direction, thereby providing a more balanced force for the rotating shaft 14.
[0048] In some embodiments, the depth of the deformation space 134 along the radial direction of the rotating shaft 14 is H, the circumference of the plane of the rolled connecting member 13 in the radial direction of the rotating shaft 14 is C, and 1 / 3C≤H≤2 / 3C.
[0049] This helps ensure that the deformation space 134 has sufficient depth along the radial direction of the rotating shaft 14, thereby helping to ensure that the deformation space 134 has an appropriate size, so that the deformation space 134 can provide sufficient space for the rolled portion 132 to deform, so that the rolled portion 132 can be deformed better.
[0050] In some embodiments, a side of the limiting portion 133 facing the rotating shaft 14 is provided with an avoidance surface 1333, and the avoidance surface 1333 avoids the rotating shaft 14. In this way, the limiting portion 133 can avoid the rotating shaft 14 through the avoidance surface 1333, which helps to reduce the situation where the limiting portion 133 hinders the rotation of the rotating shaft 14, thereby helping to ensure the smooth rotation of the rotating shaft 14.
[0051] In some embodiments, the curling protection member 121 is tightly matched with the curling connection member 13 to fix the curling protection member 121 relative to the curling connection member 13 .
[0052] This helps ensure the stability of the curling protection piece 121 on the curling connector 13, helps reduce the possibility of the curling protection piece 121 loosening from the curling connector 13, and thus helps ensure the deformation limiting effect of the curling protection piece 121 on the curling connector 13.
[0053] In some embodiments, the curling protection member 121 and the curling connector 13 are interference-fitted to fix the curling protection member 121 relative to the curling connector 13. For example, the size of the curling portion 132 is designed to overlap the size of the curling protection member 121, thereby achieving a tight connection between the curling connector 13 and the curling protection member 121.
[0054] This helps ensure the stability of the curling protection piece 121 on the curling connector 13, helps reduce the possibility of the curling protection piece 121 loosening from the curling connector 13, and thus helps ensure the deformation limiting effect of the curling protection piece 121 on the curling connector 13.
[0055] Please also read Figure 3 , Figure 4 and Figure 7 In some embodiments, the rolled connector 13 further includes an axial hole 1323 formed by the rolled portion 132 and a deformation opening 1324 connecting the axial hole 1323 and the accommodating space 1214 , and the rotating shaft 14 is inserted into the axial hole 1323 .
[0056] In this way, the rolled portion 132 can be deformed through the deformation opening 1324 so that the rolled portion 132 can be pressed against the rotating shaft 14, thereby stopping the rotating shaft 14 from rotating. The deformation opening 1324 also helps to restore the deformation of the rolled portion 132, thereby helping to reduce the situation where the rolled portion 132 is damaged by being in an extruded state for a long time.
[0057] For example, when the rotating shaft 14 rotates, the curling portion 132 can be deformed through the deformation opening 1324 and abut against the rotating shaft 14. When the torque acting on the rotating shaft 14 is greater than the applied force, the rotating shaft 14 can overcome the applied force and rotate, so that the support member 11 and the curling protection member 121 can rotate relative to each other; when the torque acting on the rotating shaft 14 disappears, the rotating shaft 14 can stop rotating under the action of the applied force and remain in the rotated position, so that the support member 11 and the curling protection member 121 can stop rotating and remain in the rotated state, and the support member 11 and the curling protection member 121 will not rotate freely due to the disappearance of the torque.
[0058] In some embodiments, a return escape space 1213 is formed between the outer side surface 1311 of the hole wall of the shaft hole 1323 and the side wall 1211 of the accommodating space 1214 , and the return escape space 1213 is disposed close to the deformation opening 1324 .
[0059] In this way, the reset avoidance space 1213 can provide space for the curled portion 132 to deform, which helps to reduce the situation where the curled portion 132 cannot be deformed, and also helps to reduce the situation where the curled connector 13 and the curled protective member 121 are stuck, thereby facilitating the disassembly of the curled connector 13 and the curled protective member 121, and facilitating the maintenance and replacement of the curled connector 13 and the curled protective member 121.
[0060] In some embodiments, the inner side surface 1312 of the hole wall of the shaft hole 1323 is provided with a first self-locking plane 1313, and the rotating shaft 14 includes a second self-locking plane 141. When the bracket 100 is in the storage state, the first self-locking plane 1313 contacts the second self-locking plane 141.
[0061] In this way, when the bracket 100 is stored, the first self-locking plane 1313 contacts the second self-locking plane 141, so that there can be a self-locking force between the two, which helps to reduce the situation where the bracket 100 is opened due to shaking, gravity, etc. when stored. The self-locking force also allows the bracket 100 to automatically rebound and close within a certain opening angle range. For example, the bracket 100 can automatically rebound and close within an opening angle range of 0° to 15°, thereby eliminating the need for the user to manually close the bracket 100.
[0062] When the bracket 100 needs to be opened, an external force can be applied to the bracket 100. When the external force acting on the bracket 100 is greater than the self-locking force, the bracket 100 is opened. The bracket 100 is opened in a simple manner and is convenient for the user to operate.
[0063] Please also read Figures 8 to 10 In some embodiments, the rolled portion 132 is surrounded by an axial hole 1323, the limiting portion 133 is located at one end of the rolled portion 132 in the length direction and at the opening of the axial hole 1323, the limiting space 1215 is provided on the end surface of one end of the rolled protection piece 121, the rolled portion 132 is inserted into the accommodating space 1214 and the limiting portion 133 is clamped in the limiting space 1215.
[0064] In this way, the curling protection piece 121 can be sleeved on the curling connector 13 through the limiting portion 133, which helps to ensure the stability of the curling protection piece 121 sleeved on the curling connector 13, helps to reduce the situation where the curling protection piece 121 loosens from the curling connector 13, and also helps to improve the compactness of the structure of the bracket 100.
[0065] In some embodiments, the limiting portion 133 is formed by the curling portion 132 protruding in a direction away from the shaft hole 1323, such as Fig. 9 This helps ensure that the limiting portion 133 can be locked in the limiting space 1215, and also helps reduce the situation where the limiting portion 133 is located in the shaft hole 1323 and hinders the rotation of the shaft 14.
[0066] In some embodiments, the limiting space 1215 is connected to the shaft hole 1323 , which helps to improve the compactness of the structure of the bracket 100 .
[0067] In some embodiments, the axial dimension of the limiting portion 133 in the shaft hole 1323 is smaller than the axial dimension of the rolled portion 132 in the shaft hole 1323 , and the axial depth of the limiting space 1215 in the shaft hole 1323 is smaller than the axial depth of the accommodating space 1214 in the shaft hole 1323 .
[0068] This helps reduce the size and volume of the limiting portion 133, thereby helping to reduce consumables of the rolled connector 13 and saving manufacturing costs.
[0069] In some embodiments, the axial dimension of the limiting portion 133 in the shaft hole 1323 is equal to the axial dimension of the rolled portion 132 in the shaft hole 1323 , and the axial depth of the limiting space 1215 is equal to the axial depth of the accommodating space 1214 in the shaft hole 1323 .
[0070] This helps to increase the contact area between the curling connector 13 and the curling protection member 121 , helps to improve the stability of the curling protection member 121 assembled on the curling connector 13 , and also helps the curling connector 13 to provide a more balanced force for the rotating shaft 14 .
[0071] Re-read Figure 4 In some embodiments, the curling protection member 121 may further include a connecting portion 123 , and the bracket 100 is connected to an outer member 12 via the connecting portion 123 .
[0072] Among them, the support member 11 and the outer member 12 can both be annular frames, for example, the support member 11 and the outer member 12 can both be rectangular ring brackets, circular ring brackets, etc., then the bracket 100 and the outer member 12 can be used as a bracket to meet the use requirements for placing objects, electronic equipment, etc.
[0073] In some embodiments, Fig.11 As shown, the bracket 100 and the external component 12 can be used only as connecting functional parts. By connecting the bracket 100 and the external component 12 as a whole to the protective shell of the electronic device as connecting functional parts, the overall structure has corresponding functions. For example, the external component 12 is connected to the protective shell of the electronic device, and the entire structure can be used as an electronic device bracket.
[0074] In some embodiments, the bracket 100 itself can be used only as a connecting functional part. By connecting the bracket 100 as a connecting functional part to the shell body of the electronic device, the overall structure has the corresponding function. For example, the connecting part 123 is directly connected to the protective shell of the electronic device, and the entire structure can be used as an electronic device bracket.
[0075] In summary, the bracket 100 provided by the embodiment of the utility model, the rotating shaft 14 of the bracket 100 is assembled on the rolled connecting member 13, and the support member 11 is rotatably connected with the rolled connecting member 13 through the rotating shaft 14. The rolled protective member 121 is sleeved on the rolled connecting member 13 and relatively fixed with the rolled connecting member 13. In this way, the rolled protective member 121 can limit the outward deformation of the rolled connecting member 13, so that the rolled connecting member 13 can be deformed within a certain range, thereby helping to reduce the situation where the rolled connecting member 13 is damaged due to excessive deformation, and the rolled protective member 121 also helps to reduce the situation where foreign impurities such as dust and particles enter the rolled connecting member 13 and the rotating shaft 14, thereby providing certain protection for the rolled connecting member 13 and the rotating shaft 14, and also helps to reduce the situation where the rolled connecting member 13 is exposed to the rolled protective member 121, which helps to reduce the situation where the rolled connecting member 13 is damaged.
