Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge and a mobile phone holder. Background Technology

[0002] A phone stand can be mounted on the back of a phone or phone case to support the phone and tilt it on a table. In this technology, the phone stand includes two relatively rotatable frames. One frame connects to the phone or phone case, and the other supports the phone on the table. The frames can be folded or unfolded for easy storage and use when rotating relative to each other. Both frames have through holes, and a pivot with an interference fit passes through these holes, allowing the frames to rotate relative to each other with a certain damping force to maintain their current rotation angle. However, because the cross-sections of the through holes and the pivot are circular, the damping force remains constant during rotation, resulting in a less than ideal user experience. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the first aspect of the present invention proposes a hinge with a better feel.

[0004] The second aspect of this utility model also proposes a mobile phone holder.

[0005] A rotating shaft according to a first aspect of the present invention includes a spindle, a first rotating member, and a second rotating member. The first rotating member has a through hole, through which the spindle passes and is interference-fitted with the wall of the through hole. The first rotating member has a first end and a second end arranged circumferentially on the spindle. The first rotating member can rotate relative to the spindle so that the first end and the second end can move closer or further apart to adjust the diameter of the through hole. The first rotating member has a guide surface. The second rotating member has a groove extending radially along the spindle. One end of the spindle is slidably disposed in the groove. The end of the first rotating member near the first rotating member has an abutment portion. When the first rotating member rotates relative to the spindle, the abutment portion moves along the guide surface and pushes the first rotating member so that the first rotating member drives the spindle to slide along the groove.

[0006] A rotating shaft according to an embodiment of the present utility model has at least the following technical effects:

[0007] In the rotating shaft of this application, since the spindle passes through the through hole of the first rotating member and is interference-fitted with the hole wall, when the first rotating member is driven to rotate in the forward direction relative to the spindle, so that the first end and the second end of the first rotating member arranged along the circumference of the spindle move closer to each other, the diameter of the through hole will decrease, thereby increasing the damping between the first rotating member and the spindle; when the first rotating member is driven to rotate in the reverse direction relative to the spindle, so that the first end and the second end of the first rotating member arranged along the circumference of the spindle move away from each other, the diameter of the through hole will increase, thereby decreasing the damping between the first rotating member and the spindle. By employing the hinge of this application in the phone holder, when the phone holder needs to be closed, the first rotating member rotates forward relative to the spindle, and the first end of the first rotating member moves closer to the second end, increasing the damping between the first rotating member and the spindle, thus requiring more force to close the phone holder; when the phone holder needs to be opened, the first rotating member rotates in the opposite direction relative to the spindle, and the first end of the first rotating member moves away from the second end, decreasing the damping between the first rotating member and the spindle, thus requiring less force to open the phone holder. Therefore, by employing the hinge of this application in the phone holder, the phone holder can have a light opening and heavy closing feel during use, thereby improving the user experience of the phone holder using the hinge of this application.

[0008] According to a first aspect embodiment of the present invention, a rotating shaft has a first positioning structure on its circumferential surface and a second positioning structure on the wall of a through hole. The first positioning structure can abut against the second positioning structure to prevent the first rotating member from continuing to rotate relative to the spindle.

[0009] According to a first aspect embodiment of the present invention, a rotating shaft has a first plane on its circumferential surface and a second plane adapted to the first plane on the wall of a through hole. The first plane constitutes a first positioning structure and the second plane constitutes a second positioning structure.

[0010] According to a first aspect embodiment of the present invention, a rotating shaft has a first rotating member that protrudes outward at one end of the spindle axis to form a guide portion. The first rotating member is also provided with an arc-shaped relief groove. The relief groove and the guide portion are distributed along the circumference of the spindle. A guide surface is formed on the guide portion. The first rotating member can rotate around the spindle under the action of an external force so that the abutment portion moves along the relief groove or along the guide surface.

[0011] According to a first aspect of the present invention, a rotating shaft includes a guide surface comprising a first guide segment, a second guide segment, and a third guide segment connected sequentially along the circumference of a through hole. The second guide segment is an arc surface, and the center of curvature is located on the axis of the through hole. Both the first guide segment and the third guide segment are used to guide the abutment portion to move to abut against the second guide segment.

[0012] A mobile phone holder according to a second aspect of the present invention includes a hinge as described in the above embodiments.

[0013] According to a second aspect of the present invention, a rotating shaft further includes a first frame and a second frame. The first rotating member includes a damping part and a first connecting part connected to each other. The damping part is bent to define a through hole. The damping part forms a first end and a second end at both ends of the through hole in the circumferential direction. The first connecting part is detachably connected to the first frame, and the second frame is detachably connected to the second rotating member.

[0014] According to a second aspect of the present invention, a rotating shaft has a first connecting portion connected to a first end.

[0015] According to a second aspect embodiment of the present invention, a rotating shaft includes a second connecting part and a mounting part. The second connecting part is detachably connected to a second frame, and the mounting part is provided with a sliding groove and is detachably connected to the second connecting part.

[0016] According to a second aspect embodiment of the present invention, a rotating shaft has a mounting portion with a snap-fit ​​protrusion and a second connecting portion with a snap-fit ​​hole, wherein the snap-fit ​​protrusion snaps into the snap-fit ​​hole.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 5 A rotating shaft according to the first aspect of this utility model will be described in detail.

[0033] refer to Figures 1 to 5According to a first aspect embodiment of the present invention, a rotating shaft includes a spindle 100, a first rotating member 200, and a second rotating member 300. The first rotating member 200 has a through hole 201. The spindle 100 passes through the through hole 201 and is interference-fitted with the wall of the through hole 201. The first rotating member 200 has a first end 210 and a second end 220 arranged circumferentially on the spindle 100. The first rotating member 200 can rotate relative to the spindle 100, allowing the first end 210 and the second end 220 to move closer or further apart to adjust the diameter of the through hole 201. The rotating member 200 is provided with a guide surface 202; the second rotating member 300 is provided with a groove 301 extending radially along the spindle 100, one end of the spindle 100 is slidably disposed in the groove 301, and the first rotating member 200 is provided with an abutment portion 302 at one end near the first rotating member 200; wherein, when the first rotating member 200 rotates relative to the spindle 100, the abutment portion 302 moves along the guide surface 202, and the abutment portion 302 pushes the first rotating member 200, so that the first rotating member 200 drives the spindle 100 to slide along the groove 301.

[0034] In the rotating shaft of this application, since the spindle 100 passes through the through hole 201 of the first rotating member 200 and is interference-fitted with the hole wall of the through hole 201, when the first rotating member 200 is driven to rotate in the forward direction relative to the spindle 100, so that the first end 210 and the second end 220 arranged along the circumference of the spindle 100 on the first rotating member 200 approach each other, the diameter of the through hole 201 will decrease, thereby increasing the damping between the first rotating member 200 and the spindle 100; when the first rotating member 200 is driven to rotate in the reverse direction relative to the spindle 100, so that the first end 210 and the second end 220 arranged along the circumference of the spindle 100 on the first rotating member 200 move away from each other, the diameter of the through hole 201 will increase, thereby decreasing the damping between the first rotating member 200 and the spindle 100. By employing the hinge of this application in the phone holder, when the phone holder needs to be closed, the first rotating member 200 rotates forward relative to the spindle 100, and the first end 210 of the first rotating member 200 moves closer to the second end 220. The damping between the first rotating member 200 and the spindle 100 increases, requiring more force to be applied when the phone holder is closed. When the phone holder needs to be opened, the first rotating member 200 rotates in the opposite direction relative to the spindle 100, and the first end 210 moves away from the second end 220. The damping between the first rotating member 200 and the spindle 100 decreases, requiring less force to be applied when the phone holder is opened. Therefore, by employing the hinge of this application in the phone holder, the phone holder can have a light opening and heavy closing feel during use, thereby improving the user experience of the phone holder using the hinge of this application.

[0035] Understandably, by driving the first rotating member 200 to rotate forward relative to the spindle 100 until the guide surface 202 on the first rotating member 200 abuts against the contact portion 302 of the second rotating member 300, the first rotating member 200 continues to rotate forward relative to the spindle 100, and the contact portion 302 moves along the guide surface 202. During this process, under the counter-pushing of the contact portion 302, the first rotating member 200 drives the spindle 100 to slide forward in the slide groove 301, and the first rotating member 200 can approach the second rotating member 300. By driving the first rotating member 200 to rotate in the opposite direction relative to the spindle 100 until the guide surface 202 on the first rotating member 200 disengages from the contact portion 302 of the second rotating member 300, during this process, under the action of the weight of the first rotating member 200 itself, the first rotating member 200 drives the spindle 100 to slide in the opposite direction in the slide groove 301, and the first rotating member 200 can move away from the second rotating member 300. Furthermore, when the hinge of this application is applied to a mobile phone holder, the first frame of the mobile phone holder is connected to the first rotating member 200, the second frame of the mobile phone holder is connected to the second rotating member 300, and the slide groove 301 extends vertically. Thus, when the first frame rotates forward relative to the second frame, the mobile phone holder opens. Driven by the first rotating member 200, the spindle 100 moves upward along the slide groove 301 to achieve the raising of the first frame. When the first frame rotates in the opposite direction relative to the second frame, the mobile phone holder closes. Under the action of the gravity of the first rotating member 200 itself, the spindle 100 moves downward along the slide groove 301 to achieve the lowering of the second frame.

[0036] Specifically, the second rotating member 300 and the spindle 100 are fixed relative to each other in the circumferential direction of the spindle 100. For example, the end of the spindle 100 is provided with a slidable mounting section that passes through the slide groove 301, and the cross-sectional shape of the mounting section is square.

[0037] refer to Figure 3 and Figure 5 In some embodiments of this utility model, a first positioning structure 110 is provided on the circumferential surface of the mandrel 100, and a second positioning structure 230 is provided on the wall of the through hole 201. The first positioning structure 110 can abut against the second positioning structure 230 to prevent the first rotating member 200 from continuing to rotate relative to the mandrel 100. It can be understood that by providing the first positioning structure 110 on the circumferential surface of the mandrel 100 and the second positioning structure 230 on the wall of the through hole 201, when the first rotating member 200 rotates relative to the mandrel 100 to a preset angle, the first positioning structure 110 abuts against the second positioning structure 230. At this time, the cooperation of the first positioning structure 110 and the second positioning structure 230 can prevent the first rotating member 200 from rotating relative to the mandrel 100, thereby achieving self-locking between the first rotating member 200 and the mandrel 100.

[0038] like Figure 3 and Figure 5 As shown, in some embodiments, the circumferential surface of the mandrel 100 includes a first plane, and the wall of the through hole 201 is provided with a second plane adapted to the first plane. The first plane constitutes a first positioning structure 110, and the second plane constitutes a second positioning structure 230. It can be understood that when the first rotating member 200 rotates relative to the mandrel 100 to a preset angle, the first plane on the circumferential surface of the mandrel 100 will fit against the second plane on the wall of the through hole 201, thereby hindering the first rotating member 200 from rotating relative to the mandrel 100.

[0039] Specifically, the cross-sectional shape of the mandrel 100 is D-shaped.

[0040] refer to Figure 4 and Figure 5 In some embodiments of this utility model, the first rotating member 200 protrudes outward at one end of the spindle 100 along the axial direction to form a guide portion 240. The first rotating member 200 is also provided with an arc-shaped relief groove 203. The relief groove 203 and the guide portion 240 are distributed along the circumference of the spindle 100. The guide surface 202 is formed on the guide portion 240. The first rotating member 200 can rotate around the spindle 100 under the action of external force so that the abutment portion 302 can move along the relief groove 203 or along the guide surface 202. Understandably, when the user drives the first rotating member 200 to rotate around the spindle 100, and the abutting part 302 moves along the arc-shaped clearance groove 203, the first rotating member 200 rotates around the spindle 100, and the spindle 100 and the second rotating member 300 remain relatively stationary. When the abutting part 302 moves to abut against the guide surface 202 and the abutting part 302 rotates along the guide surface 202, the first rotating member 200 drives the spindle 100 to slide in the slide groove 301.

[0041] like Figure 4 and Figure 5 As shown, in some embodiments, the guide surface 202 includes a first guide segment 202a, a second guide segment 202b, and a third guide segment 202c connected sequentially along the circumference of the through hole 201. The second guide segment 202b is an arc surface, and the center of curvature is located on the axis of the through hole 201. The first guide segment 202a and the third guide segment 202c are both used to guide the abutment portion 302 to move to abut against the second guide segment 202b.

[0042] It is understandable that during the rotation of the first rotating member 200 relative to the second rotating member 300, when the abutment portion 302 is located within the clearance groove 203, the first rotating member 200 rotates normally relative to the second rotating member 300. When the first rotating member 200 rotates relative to the second rotating member 300 until the abutment portion 302 abuts against the first guide section 202a, under the guidance of the first guide section 202a, while the first rotating member 200 rotates relative to the second rotating member 300, the first rotating member 200 drives the spindle 100 to slide forward along the slide groove 301. When the first rotating member 200... When the first rotating member 200 rotates relative to the second rotating member 300 until the abutting part 302 abuts against the second guide section 202b, since the curvature center of the second guide section 202b is located on the axis of the through hole 201, the first rotating member 200 only rotates relative to the second rotating member 300. When the first rotating member 200 rotates relative to the second rotating member 300 until the abutting part 302 abuts against the third guide section 202c, under the guidance of the third guide section 202c, while the first rotating member 200 rotates relative to the second rotating member 300, the first rotating member 200 drives the spindle 100 to slide in the opposite direction along the slide groove 301.

[0043] Specifically, the curvature centers of the first guide section 202a and the third guide section 202c are not collinear with the axis of the through hole 201.

[0044] The following is for reference. Figures 3 to 5 A mobile phone holder according to a second aspect embodiment of the present utility model will be described in detail.

[0045] A mobile phone holder according to a second aspect embodiment of the present invention includes the pivot described in the first aspect embodiment. By employing the pivot of this application in the mobile phone holder, when the mobile phone holder is closed, the first rotating member 200 rotates in the forward direction relative to the spindle 100, and the damping between the first rotating member 200 and the spindle 100 is relatively large, requiring more force to be applied when closing the mobile phone holder; when opening, the first rotating member 200 rotates in the reverse direction, and the damping between the first rotating member 200 and the spindle 100 is relatively small, requiring less force to be applied when opening the mobile phone holder. This results in the mobile phone holder having a function of easy opening and heavy closing, thus providing a better feel.

[0046] refer to Figure 3 and Figure 5In some embodiments of this utility model, the mobile phone holder further includes a first frame and a second frame. The first rotating member 200 includes a damping part 250 and a first connecting part 260 connected together. The damping part 250 is bent to define a through hole 201. The damping part 250 forms a first end 210 and a second end 220 at both ends of the through hole 201 in the circumferential direction. The first connecting part 260 is detachably connected to the first frame, and the second frame is detachably connected to the second rotating member 300. It can be understood that since the first connecting part 260 is connected to the first frame and the second connecting part 310 is connected to the second frame, when the user drives the first frame to rotate, the first frame can drive the first connecting part 260 to rotate, thereby the first rotating member 200 can rotate relative to the second rotating member 300, so as to realize the rotation of the first frame relative to the second frame.

[0047] It is understandable that by detachably connecting the first frame and the first connecting part 260, and detachably connecting the second frame and the second rotating part 300, the disassembly and installation of the rotating shaft are facilitated, thereby facilitating the replacement of the rotating shaft.

[0048] Specifically, the first frame is a mobile phone support frame, and the second frame is a mobile phone casing.

[0049] like Figure 3 and Figure 5 As shown, in some embodiments, the first connecting portion 260 is connected to the first end 210. It can be understood that by connecting the first connecting portion 260 to the first end 210, when the user rotates the first frame, the first frame drives the first connecting portion 260 to rotate, thereby driving the first end 210 to rotate, so that the first connecting portion 260 can more smoothly drive the first end 210 closer to or away from the second end 220 during the rotation.

[0050] Specifically, the first connecting part 260 and the damping part 250 are integrally formed.

[0051] refer to Figure 4 and Figure 5 In some embodiments of this utility model, the second rotating member 300 includes a second connecting part 310 and a mounting part 320. The second connecting part 310 is detachably connected to the second frame, and the mounting part 320 is provided with a sliding groove 301, and the mounting part 320 is detachably connected to the second connecting part 310. It can be understood that by providing a sliding groove 301 on the mounting part 320 and detachably connecting the mounting part 320 and the second connecting part 310, it is convenient for users to install or remove the mobile phone holder.

[0052] like Figure 5As shown, in some embodiments, the mounting portion 320 is provided with a snap-fit ​​protrusion 321, and the second connecting portion 310 is provided with a snap-fit ​​hole 311, with the snap-fit ​​protrusion 321 snapping into the snap-fit ​​hole 311. It can be understood that by snapping the snap-fit ​​protrusion 321 on the mounting portion 320 into the snap-fit ​​hole 311 on the second connecting portion 310, a detachable connection between the second connecting portion 310 and the mounting portion 320 is achieved. The structure of the snap-fit ​​protrusion 321 and the snap-fit ​​hole 311 is relatively simple and easier to manufacture.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
