Description

Technical Field

[0001] This utility model belongs to the field of mobile phone holder technology, specifically relating to a three-joint rotating pressure-reducing mobile phone holder. Background Technology

[0002] A phone stand is a mobile phone accessory that is fixed to the back of a phone or phone case to support the phone. Existing phone stands include the following types: 1. Those with only a single support function, structurally consisting of a fixed ring and a flip ring; the flip ring can be flipped inwards to fold onto the fixed ring, and can also be flipped outwards to adjust the support angle; 2. Those with both support and rotation functions, providing support while the flip ring can rotate on the fixed ring. Existing phone stands have the following problems: 1. Because the support component only includes the flip ring, the support height and length are limited regardless of the angle the flip ring rotates to, failing to meet the support height and length requirements of mobile phones, tablets, etc.; 2. Because the support component only includes the flip ring, the support point is a point contact between the flip ring and the table, resulting in insufficient support stability. Utility Model Content

[0003] In view of this, the present invention provides a three-joint rotating pressure-reducing mobile phone holder to solve the technical problems described in the background section.

[0004] The innovative concept of this application is to increase the adjustment range of the phone holder's support height and support length by adding support components and setting a rotating hub between the support components. At the same time, the support part is improved to multi-point support or point-line support to improve the stability of the support.

[0005] The solution provided by this utility model to solve its technical problem is as follows:

[0006] A three-joint rotating pressure-reducing mobile phone holder, characterized in that it includes a bottom outer ring, a bottom inner ring, a support member, and a buckle; the bottom inner ring is rotatably disposed inside the bottom outer ring, and the two ends of the support member are respectively hinged to the bottom inner ring and the buckle; the support member can rotate toward the bottom outer ring to fold onto the bottom outer ring, and can also rotate in the opposite direction to present an open state; the buckle can rotate toward the support member to fold onto the support member, and can also rotate in the opposite direction to present an open state.

[0007] Therefore, the three-joint rotating pressure-reducing mobile phone holder disclosed in this application not only allows the support, buckle, and bottom inner ring to rotate together within the bottom outer ring, but also allows the support and buckle to open sequentially for three-axis adjustment of support height, support length, and support angle.

[0008] Preferably, both ends of the support member are hinged to the bottom inner ring and the retaining ring respectively via a hinge assembly. The hinge assembly can be any existing component or assembly that achieves a hinged or rotating connection in the prior art. More preferably, the hinge assembly includes a first hinge sleeve, a second hinge sleeve, and a hinge shaft; the first hinge sleeve is provided with a first sleeve portion and a first fixing portion; the second hinge sleeve is provided with a second sleeve portion and a second fixing portion; the first fixing portion is used to fix the support member, and the second fixing portion is used to fix the bottom inner ring or the retaining ring; the first sleeve portion and the second sleeve portion are rotatably connected by the hinge shaft.

[0009] Preferably, the support has a plate-like structure or a rod-like structure.

[0010] Preferably, the bottom outer ring is provided with an outer ring central hole, and an axial limiting ring is provided at the edge of the outer ring central hole; the bottom inner ring is provided with an inner ring central hole, and an annular toothed ring is provided at the outer edge of the bottom inner ring; the bottom inner ring is set inside the outer ring central hole and the annular toothed ring is blocked and limited by the axial limiting ring.

[0011] Because the axial movement of the bottom inner ring is limited by the axial limiting ring on the bottom outer ring, the bottom inner ring can rotate freely within the bottom outer ring but will not fall off the bottom outer ring.

[0012] Preferably, the three-joint rotating decompression phone holder also includes a bottom cover ring; the bottom cover ring is set inside the hole of the outer ring and is used to seal and fix the bottom inner ring.

[0013] Preferably, the three-joint rotating decompression mobile phone holder also includes a pin assembly; a pin groove is also provided on the bottom outer ring; the pin assembly is disposed in the pin groove and engages with the annular toothed ring.

[0014] The ejector pin assembly can improve the feel of rotation, increase the rotational sound, and produce a pressure-reducing effect through meshing with the ring gear.

[0015] Preferably, the ejector pin assembly includes an ejector pin and an elastic element; the ejector pin is disposed within an ejector pin groove, with a portion extending out of the groove and engaging with an annular toothed ring; the elastic element is disposed within the ejector pin groove and its two ends abut against the bottom of the groove and the ejector pin, respectively. More preferably, the ejector pin is provided with a pointer head, a limiting shoulder, and a spring post; a pointer hole is provided on the side of the ejector pin groove facing the central hole of the outer ring; the pointer head extends out of the pointer hole and engages with the annular toothed ring; the limiting shoulder abuts against the inner wall of the ejector pin groove, and the elastic element is sleeved on the spring post. More preferably, the elastic element can be a spring or a sheet spring.

[0016] The ejector pin can be ejected under the action of the elastic element, and it can also return to its original position under the action of the ring gear; thus, when relative rotation occurs between the bottom outer ring and the bottom inner ring, the ejector pin can continuously perform extension and retraction movements within the ejector pin groove.

[0017] Preferably, the ejector pin assembly also includes an ejector pin groove cover; the ejector pin groove cover is disposed at the opening of the ejector pin groove and is used to encapsulate and fix the ejector pin and the elastic element.

[0018] Preferably, the three-joint rotating pressure-reducing phone holder also includes an annular film; the annular film is disposed on the bottom outer ring and is used to mount and fix the three-joint rotating pressure-reducing phone holder. More preferably, the annular film is double-sided adhesive.

[0019] Beneficial technical effects:

[0020] In use, the three-joint rotating pressure-relieving phone holder is fixed to the back of the phone or the back of the phone case using the ring-shaped film. Then, the support and buckle are unfolded in sequence. By adjusting the angle between the buckle and the support, the angle between the support and the bottom inner ring, and the relative position between the bottom inner ring and the bottom outer ring, the support height, support length, and support position of the phone holder can be flexibly adjusted. Furthermore, when there is relative rotation between the bottom inner ring and the bottom outer ring, the meshing between the pin assembly and the ring toothed ring improves the rotation feel, increases the rotation sound effect, and produces a pressure-relieving effect.

[0048] The rotatable connection between the bottom outer ring 1 and the bottom inner ring 2 forms the first rotating joint of the three-joint rotating decompression hand phone holder.

[0049] The ejector pin assembly 6 includes an ejector pin 61, an elastic element, and an ejector pin groove cover 62. The ejector pin assembly 6 is disposed within the ejector pin groove 13, and the ejector pin 61 passes through the pointer hole 14 and engages with the annular toothed ring 22. The elastic element provides elastic restoring force for the extension and retraction movement of the ejector pin 61. The ejector pin groove cover 62 is disposed at the opening of the ejector pin groove 13 and is used to encapsulate and fix the ejector pin 61 and the elastic element.

[0050] The support member 3 is used to rotatably connect the bottom inner ring 2 and the buckle 4 respectively to form the other two rotating joints of the three-joint rotating pressure relief hand phone holder. The support member 3 can be a plate-shaped structure or a rod-shaped structure.

[0051] In this embodiment, both ends of the support member 3 are respectively hinged to the bottom inner ring 2 and the buckle 4 via the hinge assembly 5; please refer to Figure 2 and Figure 3 The hinge assembly 5 includes a first hinge sleeve 51, a second hinge sleeve 52, and a hinge shaft; the first hinge sleeve 51 is provided with a first sleeve portion 511 and a first fixing portion 512; the second hinge sleeve 52 is provided with a second sleeve portion 521 and a second fixing portion 522; the first fixing portion 512 is used to fix and connect the support member 3, and the second fixing portion 522 is used to fix and connect the bottom inner ring 2 or the buckle 4; the first sleeve portion 511 and the second sleeve portion 521 form a rotary joint through the hinge shaft.

[0052] The support member 3 can rotate towards the bottom outer ring 1 to fold onto the bottom outer ring 1, or it can rotate in the opposite direction (outward from the bottom outer ring 1) to be in an open state.

[0053] The buckle 4 can rotate toward the support 3 to fold onto the support 3, or it can rotate in the opposite direction (outward from the support 3) to be in an open state.

[0054] Therefore, the three-joint rotating pressure-reducing mobile phone holder not only allows the support 3, buckle 4, and bottom inner ring 2 to rotate together within the bottom outer ring 1, but also allows the support 3 and buckle 4 to be opened sequentially for three-axis adjustment of support height, support length, and support angle.

[0055] To achieve a stable meshing connection between the ejector pin assembly 6 and the annular toothed ring 22 on the bottom inner ring 2, this application employs a special ejector pin structure. Please refer to... Figure 4 and Figure 5 The ejector pin 61 is provided with a pointer head 611, a limiting shoulder 612, and a spring post 613; wherein: the pointer head 611 and the spring post 613 extend in opposite directions; there are two limiting shoulders 612, which are symmetrically arranged on both sides of the spring post 613.

[0056] The ejector pin 61 is disposed in the ejector pin groove 13, and the pointer head 611 extends out of the pointer hole 14 and engages with the annular toothed ring 22; the limiting shoulder 612 abuts against the inner wall of the ejector pin groove 13, and the elastic element is sleeved on the spring post 613 with its two ends abutting against the bottom of the ejector pin groove 13 and the ejector pin 61, respectively. The elastic element can be a spring or a spring sheet.

[0057] The ejector pin 61 can be ejected under the action of the elastic element, and can also be returned to its original position under the action of the annular toothed ring 22; thus, when relative rotation occurs between the bottom outer ring 1 and the bottom inner ring 2, the ejector pin 61 can continuously perform telescopic movements within the ejector pin groove 13.

[0058] Principle and Effect Explanation: In use, the three-joint rotating pressure-reducing phone holder is fixed to the back of the phone or the back of the phone case using the annular film 8. Then, the support member 3 and the buckle 4 are unfolded in sequence. By adjusting the angle between the buckle 4 and the support member 3, the angle between the support member 3 and the bottom inner ring 2, and the relative position between the bottom inner ring 2 and the bottom outer ring 1, various support structures can be formed (see [link]). Figure 6 This allows for flexible adjustment of the phone holder's support height, support length, and support location.

[0059] Furthermore, when the bottom inner ring 2 and the bottom outer ring 1 rotate relative to each other, the meshing between the ejector pin assembly 6 and the ring gear 22 can improve the rotation feel, increase the rotation sound (make a clicking sound), and produce a pressure-reducing effect.
