Description

Technical Field

[0001] This application relates to the field of mobile phone holder technology, specifically to a holder base and a mobile phone holder. Background Technology

[0002] With the widespread adoption of smartphones, mobile phones have become indispensable tools for communication, navigation, entertainment, and work in people's daily lives. Against this backdrop, phone holders, as an important accessory, have seen continuous market demand growth and are widely used in various scenarios such as car driving, home office work, video viewing, and online live streaming. Suction cup phone holders are one type of phone holder that uses suction cups to adhere to surfaces such as desktops, glass surfaces, and car dashboards, thereby achieving the installation and fixation of the phone.

[0003] Chinese utility model patent application number 202223347604.2, entitled "A Suction Cup Type Mobile Phone Stand Base," is shown in the attached drawings (of this application). Figure 20 and Figure 21 The phone holder base is fixed by suction cup 101. Specifically, the suction cup mechanism 1 uses a switch 106 to flatten and lift the suction cup to achieve suction and release. The switch 106 is an upward-flipping cam mechanism. It drives the suction cup in the height H direction of the suction cup mechanism 1 through the cooperation of the rotating rod 103 and the rotating rod engaging protrusion 107. This driving force of the rotating rod 103 and the rotating rod engaging protrusion 107 is always in the height H direction of the suction cup mechanism 1, which makes the height H (or thickness) of the suction cup mechanism 1 too high. This can lead to installation restrictions in places with limited installation space or affect the adjustment freedom of its linkage mechanism 2. Utility Model Content

The first movable component is driven to connect with the second movable component through a kinematic pair; the swing center of the control component deviates from the geometric center of the support base when it swings. When the external force drives the control component to swing, the control component drives the first movable component to move forward or backward in the first direction, which in turn drives the second movable component to move upward or downward in the second direction, thereby causing the suction cup to move upward or downward at least in the middle area, thus determining whether the pressing component abuts against the skirt; wherein, the second direction is the thickness direction of the support base.

[0007] Optionally, the control member has a control handle extending from the control member body outward from the pressing member, the control handle being offset to the outer periphery of the pressing member.

[0008] Optionally, the kinematic pair includes a first mating structure and a second mating structure; in the first mating structure and the second mating structure, one is disposed on the first movable member and the other is disposed on the second movable member; The second mating structure includes a first guide surface, wherein the first mating structure is used to mate with the first guide surface to guide the second movable member to move relative to the pressing member in a second direction.

[0009] Optionally, the first mating structure includes a force-bearing end; the second mating structure includes a first receiving end and a second receiving end, which are arranged sequentially along a first direction; the first guide surface is the inner wall of the second receiving end, wherein the first guide surface is disposed on the side of the second receiving end close to the first receiving end; When the suction cup is in the adsorption state, the force-receiving end is located at the first receiving end, and the first force-receiving end abuts against the first receiving end; when the suction cup is in the release state, the force-receiving end is located at the second receiving end, and the second receiving end either avoids or accommodates the force-receiving end. The top of the first receiving end and the top of the second receiving end are at different distances from the suction cup in the second direction, and the top of the first receiving end is closer to the suction cup in the second direction; wherein, the surface of the force-bearing end is at least partially inclined or curved: the surface of the first receiving end is at least partially planar or concave.

[0010] Optionally, the first guide surface includes a first end and a second end, the first end extending toward the side where the first receiving end is located, and the second end extending toward the top of the second receiving end; From the first end to the second end, the distance between the first guide surface and the suction cup gradually changes in the second direction.

[0011] Optionally, a corner portion is provided between the first end and the first receiving end, the corner portion being used to restrict the first mating structure from moving out of the first receiving end; the corner portion protrudes toward the second side of the support base, wherein the first side and the second side are respectively located on both sides of the thickness direction of the support base; the inner wall of the first receiving end and the inner wall of the second receiving end are both smoothly connected to the corner portion.

[0012] Optionally, an elastic reset member is provided between the second movable member and the pressing member; wherein the elastic reset member provides the second movable member with a force that tends to move downward in the second direction; the elastic reset member is set off from the geometric center of the support base.

[0016] The beneficial effects of this application include at least the following: The bracket of this utility model achieves suction cup adsorption by setting a first movable member and a second movable member to drive the pressing member. When the external force drives the control member to swing, the control member drives the first movable member to move forward or backward in a first direction, which in turn drives the second movable member to move upward or downward in a second direction. This causes at least the middle area of ​​the suction cup to move upward or downward, thus determining whether the pressing member abuts against the skirt. Since the driving path is transmitted from the first direction to the second direction, the bracket is not driven entirely in the height H direction as in the prior art. Compared with the height of the rotating rod and the rotating rod locking protrusion, which are matched in the height direction, the bracket of this utility model is smaller in height, making it easier to install in places with limited installation space. At the same time, it reduces the degree of freedom of adjustment of the support arm on the bracket. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the described embodiments are merely some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] In the description of this application, the serial numbers assigned to components, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Furthermore, unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0025] In this application, all content relating to the relative position of the suction cup is referenced to a preset plane on the suction cup (e.g., the top surface of the suction cup), wherein the preset plane is perpendicular to the central axis of the suction cup.

[0026] Example See Figures 1-4 In this embodiment, a support base 100 is proposed, which includes a pressing member 200, a first movable member 300, a second movable member 400, a control member 110, and a suction cup 500; the first movable member 300, the second movable member 400, and the control member 110 are disposed on the pressing member 200. Specifically, the pressing member 200 can be the housing of the support base 100.

[0027] The suction cup 500 includes a skirt 520 and a connecting portion centrally located on one side of the skirt 520, which connects to the second movable member 400. The connecting portion is the force-bearing end. Specifically, the connecting portion can be an independent component fixedly connected to the second movable member 400, a part of the second movable member 400 integrally extended from it, or an independent component movably connected to the second movable member 400.

[0028] The control member 110 is oscillatingly connected to the pressing member 200; the control member 110 oscillates in the thickness direction of the pressing member 200; the control member 110 is drivenly connected to the first movable member 300 to drive the first movable member 300 to reciprocate relative to the pressing member 200 in a first direction. The first movable member 300 is drivenly connected to the second movable member 400 through a kinematic pair; the oscillation center of the control member 110 during oscillation is offset from the geometric center of the support base 100.

[0029] When the external force drives the control member 110 to swing, the control member 110 drives the first movable member 300 to move forward or backward in the first direction, thereby causing the first movable member 300 to drive the second movable member 400 to move upward or downward in the second direction, so that the suction cup 500 at least in the middle area moves upward or downward, thus determining whether the pressing member 200 and the skirt 520 abut against each other; wherein, the second direction is the thickness direction of the support base 100.

[0030] The bracket 100 of this utility model achieves the adsorption of the suction cup 500 by setting a first movable member 300 and a second movable member 400 to drive the pressing member 200. When the external force drives the control member 110 to swing, the control member 110 drives the first movable member 300 to move forward or backward in a first direction, thereby causing the first movable member 300 to drive the second movable member 400 to move upward or downward in a second direction. This causes the suction cup 500 to move upward or downward in at least the middle area, thus determining whether the pressing member 200 abuts against the skirt 520. Since the driving path is transmitted from the first direction to the second direction, the bracket 100 is not driven entirely in the height H direction as in the prior art. Compared with the height of the rotating rod 103 and the rotating rod locking protrusion 107, which are matched in the height direction, the bracket 100 of this utility model is smaller in height, making it easier to install in places with limited installation space. At the same time, it is easier to adjust the degree of freedom of the support arm 810 on the bracket 100.

[0031] Specifically, in one embodiment, the sliding direction of the first movable member 300 relative to the pressing member 200 is parallel to a first direction, and the sliding direction of the second movable member 400 relative to the pressing member 200 is parallel to a second direction. The second direction is parallel to the thickness direction of the support base 100. (Refer to...) Figure 5 and Figure 6 The first direction is parallel to the direction indicated by arrow x, and the second direction is parallel to the direction indicated by arrow y.

[0032] In this embodiment, the first direction and the second direction are perpendicular to each other. In some other embodiments, the first direction and the second direction may not be parallel.

[0033] When the first movable member 300 moves relative to the pressing member 200 in a direction parallel to the first direction: the first movable member 300 is used to cooperate with the second movable member 400 through a kinematic pair to guide the second movable member 400 to move relative to the pressing member 200 in a direction parallel to the second direction, so that the pressing member 200 presses against or releases the pressing against the suction cup 500.

[0034] The suction cup 500 has an adsorption state and a release state: when it is in the adsorption state, the pressing member 200 presses against the suction cup 500; when it is in the release state, the pressing member 200 is in contact with the pressing against the suction cup 500.

[0035] When the first movable component 300 moves in a direction parallel to the first direction, it drives the second movable component 400 to move in a direction parallel to the second direction via a kinematic pair, thereby achieving a switch in the direction of movement. Therefore, when switching the state of the suction cup 500, the user only needs to drive the first movable component 300 to move in a specific direction (i.e., parallel to the first direction), without occupying additional space on the top periphery of the bracket 100. Thus, the bracket 100 occupies minimal space during use.

[0036] The control member 110 has a control handle 112 extending from the body of the control member 110 outward from the pressure member 200, and the control handle 112 is biased outside the periphery 230 of the pressure member 200. The periphery 230 of the pressure member 200 refers to the direction in which the side wall of the pressure member 200 faces outward, that is, the control handle 112 is biased in the direction in which the side wall of the pressure member 200 faces outward.

[0037] like Figure 4 As shown, in this embodiment, the pressing member 200 also includes a cover 600, wherein the cover 600 can be detachably installed on the pressing member 200 by means of screw connection, snap-fit, etc.

[0038] like Figure 7 and Figure 8 As shown, a slider 210 is provided on the pressing member 200, and a groove 310 is provided on the side of the first movable member 300. The slider 210 is slidably disposed within the groove 310. The interaction between the slider 210 and the groove 310 constrains the movable direction of the first movable member 300, ensuring that the first movable member 300 can only move relative to the pressing member 200 in a direction parallel to a first direction. Other structures used to restrict the movable direction of the first movable member 300 relative to the pressing member 200 are also within the scope of protection of this application.

[0039] like Figure 7 and Figure 9 As shown, the pressing member 200 has a sliding hole 220, and the second movable member 400 has a sliding body 410. The sliding hole 220 is arranged along the second direction, wherein the sliding body 410 is slidably disposed in the sliding hole 220.

[0040] like Figure 8 As shown, the first movable member 300 includes two spaced-apart drive arms 320, wherein the space between the two drive arms 320 is used for the sliding body 410 to pass through.

[0041] The pressing member 200 may be provided with a limited rotation structure, which is used to restrict the second movable member 400 to prevent the second movable member 400 from rotating relative to the pressing member 200.

[0042] The rotation limiting structure may include a insertion groove 221 and an insertion protrusion 411.

[0043] like Figure 7 and Figure 9 As shown, the inner wall of the sliding hole 220 is provided with an axially oriented insertion groove 221, and the outer wall of the sliding body 410 is provided with an insertion protrusion 411, wherein the insertion protrusion 411 is inserted into the corresponding insertion groove 221. Through the mutual cooperation between the insertion groove 221 and the insertion protrusion 411, the second movable member 400 can only slide relative to the pressing member 200 in a direction parallel to the second direction.

[0044] like Figure 4 and Figure 9 The bottom of the sliding body 410 is provided with a mounting base 412, which is connected to the boss 510 in the upper central area of ​​the suction cup 500 by means of snap-fit, plug-in, screw connection, etc. The boss 510 is provided with a skirt 520 around its circumference. It should be noted that the boss 510 is only a component attached to the skirt 520 for fixation; its specific shape and height are not limited, and the height of the boss 510 can even be comparable to that of the skirt 520.

[0045] The kinematic pair includes a first mating structure and a second mating structure. One of the first mating structures is disposed on the first movable member 300, and the other is disposed on the second movable member 400.

[0046] In this embodiment, the first mating structure is disposed on the first movable member 300, and the second mating structure is disposed on the second movable member 400. In some other embodiments, the first mating structure may be disposed on the second movable member 400, and the second mating structure may be disposed on the first movable member 300.

[0047] Specifically, the first mating structure is disposed on the drive arm 320. Each drive arm 320 may be provided with the same number of first mating structures; for example, each drive arm 320 may be provided with one first mating structure. In this embodiment, each drive arm 320 is provided with two first mating structures. The second mating structure corresponds one-to-one with the first mating structure.

[0048] like Figure 10 As shown, the second mating structure 720 includes a first guide surface 7221, wherein the first mating structure 710 is used to mate with the first guide surface 7221 to guide the second movable member 400 to move relative to the pressing member 200 in a second direction.

[0049] like Figure 8 As shown, the first mating structure 710 includes a force-bearing end; the second mating structure 720 includes a first receiving end 721 and a second receiving end 722, which are arranged sequentially along a first direction.

[0050] The first guide surface 7221 is the inner wall of the second receiving end 722, wherein the first guide surface 7221 is disposed on the side of the second receiving end 722 close to the first receiving end 721; When the suction cup 500 is in the adsorption state, the force-receiving end is located at the first receiving end 721, and the first force-receiving end abuts against the first receiving end; when the suction cup 500 is in the release state, the force-receiving end is located at the second receiving end 722, and the second receiving end 722 either avoids or accommodates the force-receiving end. The top of the first receiving end 721 and the top of the second receiving end 722 are at different distances from the suction cup 500 in the second direction, with the top of the first receiving end 721 being closer to the suction cup 500 in the second direction. The top of the second receiving end 722 may be continuous, and its top position is the highest point relative to the suction cup 500.

[0051] The surface of the force-bearing end is at least partially inclined or curved; the surface of the first receiving end 721 is at least partially planar or concave.

[0052] The first receiving end 721 and the second receiving end 722 can be connected by a first guide surface 7221 that has a smooth transition and is inclined, so that the force-bearing end can be driven more smoothly from the first receiving end 721 to the second receiving end 722. When the force-bearing end reaches the second receiving end 722, if the second receiving end 722 is a flat or concave surface, or other surface that does not have a smooth transition like the first guide surface 7221, the force-bearing end will have difficulty sliding down from the first guide surface 7221 after reaching the second receiving end 722, resulting in a return and entering a locking / positioning state to keep the suction cup 500 in an adsorbed state. The locking / positioning state can only be released by manually operating the snap button, thereby causing the force-bearing end to disengage from the second receiving end 722, under the restoring force of the elastic reset member 420 and the variable Under the self-recovering force of the suction cup 500, the force-bearing end will re-enter the first guide surface 7221 and then return to the first receiving end 721 along the first guide surface 7221. The first mating structure 710 is provided with a second guide surface 711 that is in low contact with and interacts with the first guide surface 7221. The second guide surface 711 is an inclined surface that extends downward from the force-bearing end and transitions smoothly. The first guide surface 7221 and the second guide surface 711 correspond to each other and drive each other, making it easier to drive each other. The driving surface is large, making it less prone to shaking and reducing the error rate.

[0053] The first receiving end 721 and the second receiving end 722 are both recessed towards the first side 101 of the support base 100. Specifically, the second receiving end 722 also includes a positioning surface 7222, wherein the first guiding surface 7221 and the positioning surface 7222 are arranged at a certain angle.

[0054] The shapes of the first receiving end 721 and the second receiving end 722 both correspond to the first mating structure 710.

[0055] When the first mating structure 710 is located inside the first receiving end 721, and the top of the first mating structure 710 is opposite to the top of the first receiving end 721, that is, when the first mating structure 710 and the first receiving end 721 are engaged, the boss 510 on the suction cup 500 is lifted upward in the thickness direction by the sliding body 410 of the second movable member 400, while the pressing member 200 abuts against the skirt 520. This lifting process is the locking of the pressing member 200 after the suction cup 500 is initially adsorbed onto the surface of the object.

[0056] When the first mating structure 710 is located within the second receiving end 722, and the top of the first mating structure 710 is opposite to the top of the second receiving end 722, that is, the first mating structure 710 and the second receiving end 722 are engaged. The boss 510 on the suction cup 500 is lifted upward in the thickness direction by the sliding body 410 of the second movable member 400, and at the same time, the pressing member 200 is released from its abutment against the skirt 520. This process of releasing the lifting is to release the locking of the pressing member 200 on the suction cup 500.

[0057] The top of the first mating structure 710 is the most protruding part of the first mating structure 710 along its own protruding direction. (Refer to...) Figure 10 In the vertical direction, the uppermost part of the first mating structure 710 is the top of the first mating structure 710.

[0058] The top of the first receiving end 721 and the top of the second receiving end 722 are the deepest parts inside their own cavities along their own concave direction. (Refer to...) Figure 10 In the vertical direction, the uppermost part of the first receiving end 721 is the top of the first receiving end 721, and the uppermost position of the second receiving end 722 is the top of the second receiving end 722.

[0059] Reference Figure 10 In a direction parallel to the second direction: the tops of the first receiving end 721 and the second receiving end 722 are at different distances from the suction cup 500. In this embodiment, the top of the first receiving end 721 is closer to the suction cup 500 than the top of the second receiving end 722. Figure 10 From this perspective, after assembly is complete, the suction cup 500 is located below the second movable part 400.

[0060] The first guide surface 7221 includes a first end and a second end, the first end extending toward the side where the first receiving end 721 is located, and the second end extending toward the top of the second receiving end 722. Among them, from the first end to the second end, the distance between the first guide surface 7221 and the suction cup 500 in the second direction gradually changes.

[0061] The first guide surface 7221 includes a first end and a second end, wherein the first end and the second end are respectively located at opposite ends of the first guide surface 7221. The first end extends toward the side where the first receiving end 721 is located, and the second end extends toward the top of the second receiving end 722. (Refer to...) Figure 10 The lower left end of the first guide surface 7221 is the first end, and the upper left end of the first guide surface 7221 is the second end. The distance between the first guide surface 7221 and the suction cup 500 gradually changes from the first end to the second end.

[0062] In this embodiment, the distance between the first guide surface 7221 and the suction cup 500 gradually increases from the first end to the second end.

[0063] like Figure 10 As shown, a corner portion 723 is provided between the first end and the first receiving end 721. The corner portion 723 is used to restrict the first mating structure 710 from moving out of the first receiving end 721.

[0064] When the suction cup 500 deforms and is in an adsorption state, the first mating structure 710 is located in the first receiving end 721. At this time, the corner portion 723 achieves self-locking of the corresponding first mating structure 710, so that the first mating structure 710 can be stably embedded in the first receiving end 721 without the action of a certain external force, and will not automatically move from the first receiving end 721 into the second receiving end 722.

[0065] The corner portion 723 protrudes towards the second side 102 of the support base 100, wherein the first side 101 and the second side 102 are respectively located on both sides of the support base 100 in the thickness direction. Specifically, the corner portion 723 protrudes towards the side where the suction cup 500 is located. The protrusion may be small or inconspicuous, and it transitions relatively smoothly from the first guide surface to the first receiving end.

[0066] The inner walls of the first receiving end 721 and the second receiving end 722 are both smoothly connected to the corner portion 723.

[0067] like Figure 11 and Figure 12As shown, the second movable member 400 is provided with an elastic reset member 420. The elastic reset member 420 can be a magnet, i.e., magnets attract each other to generate a restoring force; of course, the elastic reset member 420 can also be a spring. The elastic reset member 420 provides the second movable member 400 with a force that tends to move downwards in the second direction. In typical designs, the elastic reset member 420 is positioned centrally between the suction cup 500 and the mortise member in the thickness direction of the support base 100, and most of the drive structure of the entire support base 100 is also located in this position. Since the elastic reset member 420 itself requires space for rebound and compression, this results in a looser overall structure of the support base 100 and increases the thickness and space occupied by the support base 100. Specifically, the elastic reset member 420 is offset from the geometric center of the support base 100.

[0068] The elastic reset component 420 includes a spring, and a mounting post 610 is provided on the inner top surface of the cover 600, wherein the elastic reset component 420 is sleeved on the mounting post 610. There are multiple elastic reset components 420, and each mounting post 610 corresponds to a reset component. The inner top surface of the cover 600 is the inner surface of the cover 600 facing the suction cup 500. It should be noted that the elastic reset component 420 helps to improve the user experience and achieve simple automatic reset, rather than being a necessary component; of course, by adding a fastening structure to the second mating structure 720 and the first movable component 300, the same effect of the second movable component 400 descending and releasing its lifting can also be achieved.

[0069] Furthermore, the suction cup 500 is circular, the pressing member 200 has a circular mating surface 240 that matches the suction cup 500, and the control member 110 extends out of the outer edge of the circular mating surface 240.

[0070] When the suction cup 500 is in the adsorption state, the distance between the second movable member 400 and the inner top surface is the smallest. At this time, the elastic reset member 420 is squeezed by the inner top surface of the housing and the second movable member 400, and deforms.

[0071] When the suction cup 500 is in the released state, the suction cup 500 is in a natural state (without deformation). At this time, the first mating structure 710 of the first movable member 300 is located in the second receiving end 722 of the second movable member 400. The positioning surface 7222 is in contact with the corresponding first mating structure 710 to position the first mating structure 710.

[0072] The suction cup 500 is initially in the released state: The suction cup 500 is pre-attached to the mounting surface. External force drives the first movable member 300 to move relative to the pressing member 200 in a direction parallel to the first direction, while the second movable member 400 remains unchanged in the first direction; wherein, refer to Figure 13 and Figure 14During this process, the first movable part 300 is horizontally translated to the left relative to the second movable part 400; Reference Figure 10 , Figure 14 and Figure 15 When the first movable member 300 moves in a direction parallel to the first direction, the first mating structure 710 on the first movable member 300 gradually moves out from the second receiving end 722 and moves along the guide surface. After passing the corner 723, it enters the first receiving end 721. Finally, the top of the first mating structure 710 is opposite to and in contact with the top of the first receiving end 721. During this process, the first mating structure 710 applies a component force parallel to the second direction to the second movable member 400, thereby causing the second movable member 400 to move vertically upward. Along a direction parallel to the second direction, the second movable member 400 and the pressing member 200 move in opposite directions, wherein the suction cup 500 and the pressing member 200 are in a state of moving towards each other. Thus, the skirt 520 of the suction cup 500 is pressed by the pressing member 200, thereby keeping the skirt 520 of the suction cup 500 relatively fixed to the mounting surface. During this process, the middle part of the suction cup 500 moves with the second movable member 400 and deforms. Thus, a vacuum cavity is formed between the central area of ​​the bottom surface of the suction cup 500 and the mounting surface. Under the negative pressure and the pressing of the pressing member 200, the suction cup 500 is stably adsorbed on the mounting surface.

[0073] Suction cup 500 is in the suction state: The first movable member 300 moves relative to the pressing member 200 in a direction parallel to the first direction, while the position of the second movable member 400 in the first direction remains unchanged; wherein, referring to Figure 13 and Figure 15 During this process, the first movable part 300 is horizontally translated to the right relative to the second movable part 400; Reference Figure 10 , Figure 14 and Figure 15 When the first movable member 300 moves in a direction parallel to the first direction, the first mating structure 710 on the first movable member 300 gradually moves out from the first receiving end 721, enters the second receiving end 722 after passing the corner 723, and then moves along the guide surface. Finally, the top of the first mating structure 710 is opposite to and in contact with the top of the second receiving end 722. During this process, the second movable member 400 moves vertically downward under the action of the reset member, and the pressing member 200 moves in opposite directions to the suction cup 500, thereby releasing the pressing member 200 from pressing the skirt 520. The middle part of the suction cup 500 moves with the second movable member 400, and the suction cup 500 returns to its initial state, thus releasing the suction cup 500 from adhering to the mounting surface.

[0074] In some embodiments, the first movable member 300 extends to the outside of the cover 600, thereby allowing the user to push or pull the first movable member 300 to move relative to the pressing member in a direction parallel to a first direction.

[0075] like Figure 2 and Figure 3 As shown, the collateral 200 is provided with a rotatable control member 110. The control member 110 is driven to the first movable member 300, thereby driving the first movable member 300 to move relative to the pressing member 200 in a direction parallel to a first direction. The control member 110 is rotatably connected to the abutment member via a pivot.

[0076] The control element 110 extends from the side of the cover 600 beyond the cover 600, thereby facilitating user operation.

[0077] like Figure 8 , Figure 16 and Figure 17 As shown, the control component 110 includes a linkage rod 111, and the first movable component 300 is provided with a linkage groove 330. The linkage rod 111 is located within the corresponding linkage groove 330.

[0078] like Figure 18 As shown, the linkage groove 330 includes a first abutting inner wall 331 and abutting inner wall 332 disposed opposite to each other, wherein the first abutting inner wall 331 and the second abutting inner wall 332 are disposed in a direction parallel to the first direction.

[0079] Reference Figure 5 When the control component 110 is rotated clockwise, the linkage rod 111 will abut against the first abutting inner wall 331, thereby driving the first movable component 300 to move horizontally to the left. Reference Figure 6 When the control component 110 is rotated counterclockwise, the linkage rod 111 will abut against the second inner wall 332, thereby driving the first movable component 300 to move horizontally to the right.

[0080] like Figure 19 As shown, this embodiment also proposes a mobile phone holder, including a support arm 810 and a bracket base 100 mentioned above, wherein one end of the support arm 810 is connected to the bracket base 100, and the other end is provided with a mounting part 820 for mounting a mobile phone.

[0081] The mounting part 820 can be a ball head, a magnet, etc. The ball head connects to a clamping mechanism to clamp the phone, thus enabling the phone to be installed; the magnet engages with a magnetic ring or iron ring on the phone case to also enable the phone to be installed.
