Description

Technical Field

[0001] This invention relates to the field of telecommunications technology, and more particularly to a mobile phone holder. Background Technology

[0002] With the widespread adoption of smart mobile devices, especially smartphones, their applications in navigation and information display are becoming increasingly frequent. To facilitate drivers viewing their phone information on motorcycles, electric bikes, and cars, phone holders are typically used to securely fix the phone to the vehicle. Currently, most commercially available phone holders rely on mechanical or sensor-based clamping structures to secure the phone, and their common implementation methods fall into the following three categories:

[0003] Firstly, it employs a spring-loaded clamping structure, where the clamping element is manually pulled outward to accommodate different phone widths, and the clamping is achieved by relying on the spring's restoring force. While this method offers some size adaptability, it is difficult to precisely control the clamping and releasing actions when operating with one hand.

[0004] Secondly, there are mechanisms that automatically trigger clamping based on gravity or infrared sensors, which automatically drive the clamping components to close after detecting the placement of a mobile phone. While this approach simplifies the placement process, its structure is relatively complex and costly, and it may experience false triggering or unstable response in vibrating environments.

[0005] Thirdly, the manually adjustable clamping mechanism requires pre-setting the clamping width using screws, teeth, and other adjustment components, followed by a second locking after the phone is placed in. This method is cumbersome, and the clamping force relies entirely on user experience. It is prone to causing difficulty in taking the phone out due to excessive clamping, or it may fall off during bumps due to insufficient clamping, failing to balance convenience and stability.

[0006] Therefore, how to provide a phone holder that can adapt to and securely clamp smart terminals of different sizes (such as mobile phones, tablets, etc.) while having a simple structure is an urgent problem to be solved. Summary of the Invention

[0007] This invention provides a mobile phone holder that solves the problem that existing mobile phone holders have complex structures and cannot adapt to and securely clamp smart terminals of different sizes.

[0008] The technical solution of the present invention is a mobile phone holder, comprising:

[0009] Base;

[0010] A first clamping member is connected to the base; one end of the first clamping member is provided with a supporting part;

[0011] Multiple parallel connecting rods have their first ends rotatably connected to the first clamping member via a pivot portion. Each pivot portion is provided with a reset component, which is used to drive the connecting rod to reset.

[0012] The second clamping member is connected to the second end of all the links and is configured to move the second clamping member as all the links move along an arcuate trajectory about the corresponding pivot.

[0013] Furthermore, the phone holder has a reset state and a fully open state;

[0014] When the mobile phone holder is in the reset state, the two outermost connecting rods, the first clamping member, and the second clamping member form a parallelogram.

[0015] When the phone holder is in its fully open state, the two outermost connecting rods, the first clamping member, and the second clamping member form a rectangle.

[0016] Furthermore, the reset assembly is a bidirectional torsion spring sleeved on the pivot portion, with one torsion arm of the torsion spring abutting against the base or a portion fixed to the base, and the other torsion arm abutting against the first end of the corresponding connecting rod or a portion fixed to the first end of the connecting rod.

[0017] Furthermore, anti-slip portions are provided in the side walls of the first clamping member and the second clamping member facing each other.

[0018] Furthermore, the anti-slip portion is recessed inward to form a clearance groove, which is configured such that when the smart terminal is clamped, the button area on its side is accommodated within the clearance groove.

[0019] Furthermore, a rotating assembly is provided between the first clamping member and the base, the rotating assembly being configured to enable the first clamping member to rotate continuously 360° relative to a fixed plane within the fixed plane.

[0020] Furthermore, the rotating assembly includes:

[0021] Rotating base;

[0022] A clamping base, on which a first clamping element is provided;

[0023] A first fastener passes through the rotating base and the clamping base and locks them together axially;

[0024] At least one elastic positioning post is built into the rotating base;

[0025] The clamping base is provided with a plurality of positioning grooves on the side away from the first clamping member, and the plurality of positioning grooves are arranged circumferentially around the first fastener;

[0026] The first fastener allows the rotating base and the clamping base to rotate relative to each other about their axes, and the elastic positioning pins can selectively fall into the corresponding positioning grooves to achieve positioning.

[0027] Furthermore, the clamping base is provided with a first receiving groove on the side facing the first clamping member for each reset component, and the first receiving groove is arranged around the corresponding reset component;

[0028] The first receiving groove is provided with a first sealing element, which is configured to form a sealing interface between the first receiving groove and the corresponding connecting rod.

[0029] Furthermore, a buffer assembly is provided between the base and the rotating assembly, the buffer assembly being configured to absorb and attenuate impacts or vibrations acting on the base.

[0030] Further, the buffer component includes:

[0031] A fixing cap having an inner cavity;

[0032] An elastic buffer element is disposed in the inner cavity and has a central through hole;

[0033] A second fastener passes through the retaining cap and the rotating base and locks both together;

[0034] One end of the base passes through the inner cavity and the central through hole and is connected to the locking component;

[0035] Tightening the locking member causes the elastic buffer to undergo axial compression deformation in the inner cavity, thereby providing elastic buffering between the base and the rotating assembly.

[0036] Furthermore, the elastic buffer member has multiple protrusions on the side facing the rotating base, and all of the protrusions abut against the bottom of the rotating base;

[0037] The other side of the elastic buffer is provided with multiple inwardly recessed blind holes.

[0038] Furthermore, a second receiving groove is provided on the side of the rotating base facing the clamping base. The second receiving groove is arranged around the first fastener, and all the elastic positioning posts are arranged in the area surrounded by the second receiving groove.

[0039] The second receiving groove is embedded with a second seal, and the second seal is configured to form a sealing interface between the second receiving groove and the rotating base.

[0040] Furthermore, the base includes a bracket, one end of which forms a first receiving space. A universal ball is rotatably connected within the first receiving space. The connecting rod of the universal ball passes through the inner cavity and the central through hole and is connected to the locking member.

[0041] The other end of the bracket is provided with an adapter assembly, which is used to fix the mobile phone bracket to an external carrier.

[0042] Furthermore, the adapter assembly includes a rotating part and a fixing part;

[0043] The bracket has a second accommodating space at the end away from the first accommodating space. A rotating part is rotatably connected in the first accommodating space, and a fixing part is connected to the rotating part that is not in the second accommodating space. The fixing part is used to fix the mobile phone bracket to an external carrier.

[0044] Furthermore, the bracket includes a first housing and a second housing that are interlocked with each other;

[0045] A third fastener passes through the first housing and the second housing and locks them radially, so that the first housing and the second housing together enclose the first housing space and the second housing space.

[0046] Compared with the prior art, the present invention has at least the following beneficial effects:

[0047] The first clamping member proposed in this invention is connected to the second clamping member through multiple parallel connecting rods, so that when all the connecting rods move along an arc trajectory around the corresponding pivot, the second clamping member adapts to adjust the size of the clamping space between the first clamping member and the second clamping member. Then, under the action of the spring force of the reset component, the second clamping member cooperates with the first clamping member to firmly clamp the mobile phone, and the structure is simple.

[0067] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0068] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0069] With the widespread adoption of smart mobile devices, especially smartphones, their applications in navigation and information display are becoming increasingly frequent. To facilitate drivers viewing their phone information on motorcycles, electric bikes, and cars, phone holders are typically used to securely fix the phone to the vehicle. Currently, most commercially available phone holders rely on mechanical or sensor-based clamping structures to secure the phone, and their common implementation methods fall into the following three categories:

[0070] Firstly, it employs a spring-loaded clamping structure, where the clamping element is manually pulled outward to accommodate different phone widths, and the clamping is achieved by relying on the spring's restoring force. While this method offers some size adaptability, it is difficult to precisely control the clamping and releasing actions when operating with one hand.

[0071] Secondly, there are mechanisms that automatically trigger clamping based on gravity or infrared sensors, which automatically drive the clamping components to close after detecting the placement of a mobile phone. While this approach simplifies the placement process, its structure is relatively complex and costly, and it may experience false triggering or unstable response in vibrating environments.

[0072] Thirdly, the manually adjustable clamping mechanism requires pre-setting the clamping width using screws, teeth, and other adjustment components, followed by a second locking after the phone is placed in. This method is cumbersome, and the clamping force relies entirely on user experience. It is prone to causing difficulty in taking the phone out due to excessive clamping, or it may fall off during bumps due to insufficient clamping, failing to balance convenience and stability.

[0073] Therefore, in some embodiments, such as Figure 1 and Figure 3 As shown, this invention proposes a simple mobile phone holder that adaptively and securely clamps smart terminals (such as mobile phones, tablets, etc.) of different sizes, comprising:

[0074] Base 10;

[0075] A first clamping member 20 is connected to the base 10; a support portion 203 is provided at one end of the first clamping member 20.

[0076] Multiple parallel connecting rods 30, each having its first end rotatably connected to the first clamping member 20 via a pivot 301, each having a reset component 302 within the pivot 301, the reset component 302 being used to drive the connecting rod 30 to reset.

[0077] The second clamping member 40 is connected to the second end of all the links 30 and is configured to move the second clamping member 40 as all the links 30 move along an arcuate trajectory about the corresponding pivot 301.

[0078] It should be noted that the first clamping member 20 and the second clamping member 40 proposed in this embodiment cooperate to form an adjustable clamping space, thereby clamping smart terminals of different sizes (such as mobile phones, tablets, etc.). The smart terminal proposed in this embodiment is illustrated by taking a mobile phone as an example. Furthermore, the X-axis direction proposed in this embodiment is preferably the extension direction of the second clamping member 40, and the Y-axis direction is preferably the left-right direction or the horizontal direction.

[0079] The left-right direction is preferably the Y-axis direction. The embodiment uses two links 30 as an example, but of course, the number of links 30 can also be three or more.

[0080] Furthermore, the support portion 203 proposed in this embodiment is located on the lower side of the first clamping member 20 along the X-axis direction; the support portion 203 is used to support one corner of the mobile phone and restrict the mobile phone from moving in the direction of the support portion 203.

[0081] Thus, when the phone is placed in the clamping space, the second clamping member 40 moves in the left and right direction to clamp the phone. That is, after the phone is clamped by the first clamping member 20 and the second clamping member 40, the phone cannot move downwards because it is restricted by the support part 203. Then, the phone cannot move left or right because the multiple parallel connecting rods 30 prevent the second clamping member 40 from moving in parallel in the left and right direction. It is also restricted by the arc-shaped movement trajectory of the connecting rods 30, and the second clamping member 40 always remains straight in the X-axis direction. This movement trajectory is centered on the pivot part 301, with the end of the connecting rod 30 making a circular motion. Because there are multiple connecting rods 30, the movement trajectory becomes arc-shaped.

[0082] If the phone is subjected to bumps or other upward movements, under the action of the reset component 302, frictional resistance will be generated between the phone and the corresponding contact surfaces of the first clamping member 20 and the second clamping member 40. This frictional resistance is in the X-axis direction, which means that the phone will drive the second clamping member 40 to move vertically upward. At this time, the reset component 302 undergoes greater elastic deformation. However, the second clamping member 40 is restricted by multiple parallel connecting rods 30 to move inward in an arc shape. Therefore, the more force the phone exerts in the X-axis direction and away from the support part 203, the tighter the second clamping member 40 will work with the first clamping member 20 to clamp the phone (equivalent to the second clamping member 40, under the action of the rebound force of the reset component 302, working with the first clamping member 20 to firmly clamp the phone), thereby achieving the protective function of preventing the phone from falling off.

[0083] Conversely, when removing the phone clamped by the first clamp 20 and the second clamp 40, the user only needs to gently press the second clamp 40 along the X-axis with their finger, or the user can pull the phone out along the X-axis away from the support 203 while rotating it to the right at a certain angle, thus relieving most of the frictional resistance. Essentially, if the user holds the second clamp 40, it's easy to put the phone in; pressing the second clamp 40 also makes it easy to take the phone out, but both actions require manual operation. Bumps, vibrations, or engine vibrations will not cause the phone to detach on its own.

[0084] Therefore, the first clamping member 20 of the present invention is connected to the second clamping member 40 through a plurality of parallel connecting rods 30, so that when all the connecting rods 30 move along an arc trajectory around the corresponding pivot 301, the second clamping member 40 adapts to adjust the size of the clamping space between the first clamping member 20 and the second clamping member 40. Then, under the action of the spring force of the reset component 302, the second clamping member 40 cooperates with the first clamping member 20 to firmly clamp the mobile phone, and the structure is simple.

[0085] Furthermore, the first clamping member 20 and the second clamping member 40 cooperate to clamp the side of the phone away from the camera, thereby not obstructing the phone's camera (e.g. Figure 7 (As shown).

[0086] The phone holder has a reset state and a fully open state;

[0087] like Figure 9 As shown, when the mobile phone holder is in the reset state, the two outermost connecting rods 30, the first clamping member 20 and the second clamping member 40 form a parallelogram or a near-parallelogram. At this time, the size of the clamping space formed by the cooperation of the first clamping member 20 and the second clamping member 40 is the smallest.

[0088] like Figure 8 As shown, when the mobile phone holder is in its fully open state, the two outermost connecting rods 30, the first clamping member 20 and the second clamping member 40 form a rectangle or a rectangle, at which time the clamping space formed by the first clamping member 20 and the second clamping member 40 is at its largest size.

[0089] It should be noted that the two outermost links 30 are equivalent to the two links 30 located on both sides along the X-axis among the multiple links 30.

[0090] When moving from the reset state to the maximum open state, the shape formed by the two outermost connecting rods 30, the first clamping member 20, and the second clamping member 40 gradually changes from a parallelogram to a rectangle.

[0091] In some embodiments, such as Figure 2 and Figure 3 The reset assembly 302 shown is a bidirectional torsion spring sleeved on the pivot part 301. One torsion arm of the torsion spring abuts against the base 10 or the part fixed to the base 10, and the other torsion arm abuts against the first end of the connecting rod 30 or the part fixed to the first end of the connecting rod 30.

[0092] The pivoting part 301 includes a sleeve 3011 disposed on the side of the first end of the connecting rod 30 facing the clamping base 502. Correspondingly, a pin 3012 is disposed on the clamping base 502 corresponding to the sleeve 3011. The outer diameter of the pin 3012 matches the inner diameter of the sleeve 3011, allowing the pin 3012 to precisely extend into the sleeve 3011, thereby forming a pivoting part 301 that can freely rotate about the axis of the pin 3012. This pivoting part 301 constitutes a stable and reliable rotating pair, allowing the connecting rod 30 to pivot relative to the clamping base 502.

[0093] To provide the restoring torque or springback torque for connecting rod 30, this embodiment employs a torsion spring. To ensure stable operation and a compact layout, such as... Figure 2 and Figure 5As shown, specialized receiving structures are provided on both the connecting rod 30 and the clamping base 502:

[0094] On the connecting rod 30, a first groove 303 is respectively formed around the root of each sleeve 3011; on the clamping base 502, a second groove 508 is respectively formed around the root of each pin 3012. The main body of the torsion spring is a helical coil. During installation, the helical coil is simultaneously sleeved on the outside of the sleeve 3011 and the corresponding pin 3012, and located within the installation space formed by the first groove 303 and the second groove 508. This double groove design not only provides radial and axial restraint for the torsion spring, preventing it from falling off or shifting during operation, but also makes the overall structure extremely compact, adding almost no extra volume. Then, one torsion arm of the torsion spring is inserted into and fixed in a second slot in the second groove 508, thereby ensuring that the one torsion arm remains relatively stationary with respect to the clamping base 502; the other torsion arm of the torsion spring is inserted into and fixed in a first slot 304 in the first groove 303, thereby ensuring that the other torsion arm remains relatively stationary with respect to the connecting rod 30.

[0095] Thus, without external force, the torsion spring is in its initial preload state, at which point the connecting rod 30 is in a defined "initial position" (i.e., reset state) relative to the clamping base 502. When the user applies external force to drive the second clamping member 40, causing the second clamping member 40 to move relative to the first clamping member 20 along an arc trajectory around the corresponding pivot 301 of all the connecting rods 30, the connecting rod 30 causes the helical coil of the torsion spring to undergo torsional deformation, thereby storing elastic potential energy. This allows the second clamping member 40 to cooperate with the first clamping member 20 to firmly clamp the phone under the action of the torsion spring's rebound force. Once the user removes the phone from the phone holder, the elastic potential energy stored in the torsion spring drives the connecting rod 30 and the second clamping member 40 to return to their original state. This return process is manifested as follows: the torsion spring applies a reverse torque to the connecting rod 30 through its torsion arm, forcing the connecting rod 30 to automatically and precisely rotate around the axis of the pin 3012 until it is completely restored to the "initial position," completing one complete reset cycle.

[0096] Furthermore, the specific structure of the aforementioned reset component 302 is only a preferred elastic reset solution. Depending on the different requirements of the actual application for reset force, stroke, and cost, the torsion spring can also be replaced with other types of reset components, such as: a tension spring or compression spring connecting the connecting rod 30 and the clamping base 502, or an elastic damping block (such as rubber) disposed between the contact surfaces of the two.

[0097] In some embodiments, to further increase the frictional resistance generated by the corresponding contact surfaces between the mobile phone and the first clamping member 20 and the second clamping member 40, such as... Figure 1 As shown, anti-slip portions 201 are provided in the opposite sidewalls of the first clamping member 20 and the second clamping member 40.

[0098] It should be noted that the opposite sidewalls of the first clamping member 20 and the second clamping member 40 are equivalent to the contact surfaces of the first clamping member 20 and the second clamping member 40 with the mobile phone.

[0099] In some embodiments, to ensure that the phone holder does not accidentally press the buttons on the side of the phone when holding the phone, such as... Figure 1 As shown, the anti-slip part 201 is recessed inward to form a relief groove 202, which is configured such that when the smart terminal is clamped, the button area on its side is accommodated in the relief groove 202.

[0100] It should be noted that the shape of the clearance groove 202 is preferably an isosceles trapezoid or other shape that can accommodate the button area on the side of the mobile phone, and the depth and length of the clearance groove 202 are both greater than the button protrusion of the corresponding mobile phone.

[0101] In this way, when the phone is clamped, the button area is suspended in the air and will not be continuously pressed, thus completely avoiding potential damage caused by accidental touches, misoperations, or prolonged pressing due to clamping.

[0102] In some embodiments, to adjust the angle of the phone after it is clamped by the phone holder, to facilitate the user's viewing of the phone interface and to maintain the stability of the phone screen, such as... Figure 1 and Figure 4 As shown, a rotating assembly 50 is provided between the first clamping member 20 and the base 10. The rotating assembly 50 is configured to enable the first clamping member 20 to rotate continuously 360° relative to a fixed plane within the fixed plane.

[0103] Specifically, the rotating assembly 50 includes:

[0104] Rotating base 501;

[0105] A clamping base 502 is provided with a first clamping member 20;

[0106] A first fastener 503 passes through the rotating base 501 and the clamping base 502 and locks them together axially.

[0107] At least one elastic positioning post 504 is built into the rotating base 501;

[0108] The clamping base 502 is provided with a plurality of positioning grooves 505 on the side away from the first clamping member 20, and the plurality of positioning grooves 505 are arranged circumferentially around the first fastener 503.

[0109] The first fastener 503 allows the rotating base 501 and the clamping base 502 to rotate relative to each other about their axes, and the elastic positioning pin 504 can selectively fall into the corresponding positioning groove 505 to achieve positioning.

[0110] It should be noted that the multiple positioning grooves 505 proposed in this embodiment are arranged circumferentially and evenly around the first fastener 503. Furthermore, the locking force of the first fastener 503 proposed in this embodiment is configured such that while pressing the rotating base 501 and the clamping base 502 together to prevent axial separation, they are allowed to rotate relative to each other around the axis of the first fastener 503. The resistance to this relative rotation can be controlled by adjusting the magnitude of the locking force.

[0111] In this way, after the rotating base 501 and the clamping base 502 are locked by the first fastener 503, the tops of the two opposing elastic positioning pins 504 built into the rotating base 501 will rotate on the annular track surface formed by multiple positioning grooves 505. Each time the top of the elastic positioning pin 504 enters a positioning groove 505 on the track surface, it is a feedback of one gear, thereby realizing the manual rotation of the phone holder angle. It has a damping force effect, which can ensure that the vibration of environmental factors will not cause the phone holder to rotate arbitrarily.

[0112] Among them, a bushing 509 is fitted on the first fastener 503. The bushing 509 is set as a sliding bearing between the first fastener 503 and the inner hole of the rotating base 501, thereby effectively reducing the coefficient of friction during rotation and making the rotation of the clamping base 502 relative to the rotating base 501 smoother.

[0113] Among them, such as Figure 4 As shown, the elastic positioning post 504 includes a housing 5041, a spring, and a ball bearing 5042. The spring is housed within the housing 5041, and the ball bearing 5042 is mounted on the top of the spring, allowing a portion of the ball bearing 5042 to continuously extend beyond the housing 5041 under the elastic force of the spring. When the rotating base 501 and the clamping base 502 are assembled, the extended portion of the ball bearing 5042 maintains pressure contact with the annular track surface formed by the multiple positioning grooves 505 of the clamping base 502.

[0114] During relative rotation, the ball 5042 slides along the annular track surface. When the rotation reaches a specific angle, the ball 5042, under the action of the spring force, enters a positioning groove 505 on the track surface, achieving indexing positioning. Continued rotation requires overcoming the spring force to make the ball 5042 roll out of the current positioning groove 505 and slide into the next positioning groove 505.

[0115] In some embodiments, such as Figure 2As shown, the clamping base 502 is provided with a first receiving groove on the side facing the first clamping member 20 for each of the reset components 302, and the first receiving groove is arranged around the corresponding reset component 302.

[0116] The first receiving groove is provided with a first sealing element 506, which is configured to form a sealing interface between the first receiving groove and the corresponding connecting rod 30.

[0117] It should be noted that the shape of the first receiving groove is preferably a circular annular groove or a square frame groove.

[0118] In this way, the first sealing element 506 is located in the first receiving groove and is axially compressed between the clamping base 502 and the first clamping element 20, generating radial deformation. This generates rotational damping between the clamping base 502 and the first clamping element 20, and can tightly fill the assembly gap between the clamping base 502 and the first clamping element 20, forming a continuous, gapless sealing barrier. This barrier can effectively prevent liquid water, water vapor or dust from invading the interior from the rotational joint, thus achieving dynamic rotational sealing.

[0119] In some embodiments, such as Figure 1 and Figure 6 As shown, a buffer assembly 60 is provided between the base 10 and the rotating assembly 50. The buffer assembly 60 is configured to absorb and attenuate the impact or vibration acting on the base 10.

[0120] Specifically, the buffer component 60 includes:

[0121] A fixing cap 601 has an inner cavity 602;

[0122] An elastic buffer 603 is disposed in the inner cavity 602 and has a central through hole 604;

[0123] The second fastener 605 passes through the fixing cap 601 and the rotating base 501 and locks them together;

[0124] One end of the base 10 passes through the inner cavity 602 and the central through hole 604 and is connected to the locking member 606;

[0125] Tightening the locking member 606 causes the elastic buffer member 603 to undergo axial compression deformation in the inner cavity 602, thereby providing elastic buffering between the base 10 and the rotating assembly 50.

[0126] It should be noted that the locking element 606 is preferably an anti-loosening nut. The elastic buffer element 603 is at least one of silicone, rubber, foam, or thermoplastic elastomer. Furthermore, the second fastener 605 proposed in this embodiment passes through the fixing cap 601 and the rotating base 501 and locks both radially.

[0127] In this way, by adjusting the tightening torque of the locking member 606, the pre-compression amount of the elastic buffer member 603 can be controlled, so that the elastic buffer member 603 generates appropriate axial compression deformation in the inner cavity 602, thereby forming an elastic connection between the universal ball 103 and the fixed cap 601, thus adapting to different weights or vibration intensities and optimizing the user experience.

[0128] When the phone holder is subjected to vibrations from road bumps or the vehicle itself, the vibration is transmitted through the base 10 to the elastic buffer 603, which absorbs and attenuates the vibration through its elastic deformation, greatly reducing the shaking transmitted to the first clamp 20 and the phone, ensuring the stability of the phone screen, and avoiding damage to the phone components, especially the image stabilization module of the phone camera.

[0129] Furthermore, the elastic buffer 603, the first fastener 503, and part of the rotating base 501 are all built into the fixing cap 601, resulting in a simple overall structure with no exposed moving parts and good durability; and the fixing cap 601 can limit the elastic buffer 603.

[0130] Specifically, such as Figure 6 As shown, the elastic buffer 603 has a plurality of protrusions 607 on the side facing the rotating base 501, and the protrusions 607 all abut against the bottom of the rotating base 501.

[0131] The other side of the elastic buffer 603 is provided with a plurality of inwardly recessed blind holes 608.

[0132] It should be noted that the multiple protrusions 607 and multiple blind holes 608 proposed in this embodiment are arranged circumferentially at equal distances around the central through hole 604, and each blind hole 608 extends along the axial or Z-axis direction.

[0133] In this way, the protrusion 607 can ensure that the elastic buffer 603 has a deformation space along the axial direction of the elastic buffer 603 when vibrating, and the blind hole 608 can reserve deformable space for the deformation of the elastic buffer 603, thereby improving the effect of the elastic buffer 603 in absorbing and attenuating vibration.

[0134] In some embodiments, such as Figure 1 As shown, the rotating base 501 is provided with a second receiving groove on the side facing the clamping base 502. The second receiving groove is arranged around the first fastener 503. All the elastic positioning posts 504 are arranged in the area surrounded by the second receiving groove.

[0135] The second receiving groove is provided with a second sealing element 507, and the second sealing element 507 is configured to form a sealing interface between the second receiving groove and the rotating base 501.

[0136] It should be noted that the shape of the second receiving groove is preferably a circular annular groove or a square frame groove.

[0137] In this way, the first fastener 503 passes through the rotating base 501 and the clamping base 502 and locks them together axially. The axial locking force causes the second seal 507 to undergo axial compression and radial deformation, thereby generating rotational damping between the clamping base 502 and the rotating base 501, and tightly filling the assembly gap between the clamping base 502 and the rotating base 501, forming a continuous, gapless sealing barrier. This barrier can effectively prevent liquid water, water vapor or dust from entering the interior from the rotating joint, thus achieving dynamic rotational sealing.

[0138] In some embodiments, such as Figure 1 As shown, the bracket 101 includes a first housing 1011 and a second housing 1012 that are interlocked with each other;

[0139] The third fastener 106 passes through the first housing 1011 and the second housing 1012 and locks them radially, so that the first housing 1011 and the second housing 1012 together enclose the first receiving space 102 and the second receiving space 105.

[0140] It should be noted that the third fastener 106 is preferably a rotary handle or knob.

[0141] Thus, when the user needs to replace the universal ball 103 and / or the adapter assembly 70, the third fastener 106 can be rotated counterclockwise to move the first housing 1011 and the second housing 1012 away from each other and separate them. After the replacement is completed, the third fastener 106 is passed through the middle of the first housing 1011 and bolted to the middle of the second housing 1012. Then, the third fastener 106 is rotated clockwise to lock both radially. Of course, if the size of the universal ball 103 and / or the adapter assembly 70 is larger than the size before replacement, the effective thread depth of the third fastener 106 into the second housing 1012 will be smaller to increase the size of the corresponding accommodating space; conversely, if the size of the universal ball 103 and / or the adapter assembly 70 is smaller than the size before replacement, the effective thread depth of the third fastener 106 into the second housing 1012 will be larger to decrease the size of the corresponding accommodating space.

[0142] Furthermore, if the user feels that the universal ball 103 and / or the rotating part 701 is loose or the pre-tightness is not up to standard, the user can rotate the third fastener 106 to make the first housing 1011 and the second housing 1012 move relative to each other or in opposite directions, thereby arbitrarily adjusting the pre-tightness of the accommodating space.

[0143] In some embodiments, such as Figure 1 As shown, the base 10 includes a bracket 101, one end of which forms a first receiving space 102. A universal ball 103 is rotatably connected in the first receiving space 102. The connecting rod 104 of the universal ball 103 passes through the inner cavity 602 and the central through hole 604 and is connected to the locking member 606.

[0144] The other end of the bracket 101 is provided with an adapter component 70, which is used to fix the mobile phone bracket to an external carrier.

[0145] In this way, by loosening the third fastener 106, the entire phone holder, excluding the base 10, can tilt in any direction within a certain cone angle range with the omnidirectional ball 103 as the center, thereby realizing stepless adjustment of the phone holder in pitch and roll angles. After rotating to the first predetermined angle, the user then tightens the third fastener 106 to fix the adjusted first predetermined angle.

[0146] In some embodiments, such as Figure 1 As shown, the adapter assembly 70 includes a rotating part 701 and a fixing part 702;

[0147] The bracket 101 has a second receiving space 105 at one end away from the first receiving space 102. A rotating part 701 is rotatably connected in the first receiving space 102. A fixing part 702 is connected to the rotating part 701 that is not in the second receiving space 105. The fixing part 702 is used to fix the mobile phone bracket to an external carrier.

[0148] It should be noted that the fixing part 702 can be preferably a handlebar connector to fix the phone holder to the handlebars; or the fixing part 702 can be preferably a suction cup base to fix the phone holder to the windshield or a flat surface; or the fixing part 702 can be preferably an air vent mesh clamp to fix the phone holder to the air conditioning vent; or the fixing part 702 can be preferably an adhesive base to fix the phone holder to a flat surface such as the dashboard; or the fixing part 702 can be preferably a fixing base to permanently / semi-permanently fix the phone holder with bolts or the like; or the fixing part 702 can be preferably a magnetic base to firmly attach the phone holder to any ferrous metal surface inside the vehicle or elsewhere, without limitation. Furthermore, the rotating part 701 proposed in this embodiment can be replaced with a omnidirectional ball structure, without limitation.

[0149] In this way, by loosening the third fastener 106, the entire phone holder, except for the adapter component 70, can rotate continuously 360° relative to the axis of the rotating part 701 (this rotational movement occurs in a fixed plane perpendicular to the axis of the rotating part 701), thereby adjusting the rotation angle of the phone holder. After rotating to the second predetermined angle, the user then tightens the third fastener 106 to fix the adjusted second predetermined angle.
