[0043] 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.

[0044] The embodiments of this application are described in detail below.

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.

[0045] 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.

[0046] 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).

[0047] See Figures 1-3 In this embodiment, a suction cup device is proposed, including a housing 100, a suction cup driving device, and a suction cup 600. The suction cup driving device is disposed on the housing 100. The suction cup driving device includes a control member 200 and a follower member 300; the control member 200 includes a driving part 220 and a control part 230; the follower member 300 includes a driving part 310 and a pushing part 330, and the driving part 220 and the driving part 310 are drivenly connected; a through hole 111 is provided on the side or upper side of the housing 100. The side of the housing 100 refers to the side surface of the housing 100, and the upper side refers to the upper edge of the side surface of the housing 100 or the edge area of ​​the top surface of the housing 100, or the connection between the two, rather than the middle position of the housing 100.

[0048] The control component 200 is rotatably connected to the housing 100 through the through hole 111, and the rotation center of the rotatable connection is offset from the geometric center of the suction cup device. Specifically, the geometric center does not necessarily have to be the absolute center of the suction cup device, but can be a roughly central region offset from the absolute center. The rotatable connection can be a fixed shaft rotatable connection, or a floating or movable shaft rotatable connection.

[0049] The control unit 230 is at least partially exposed outside the housing 100; the control key can swing in the thickness direction of the suction cup device; the control member 200 is used to drive the follower 300 to reciprocate relative to the housing 100 so that the central area of ​​the back of the suction cup 600 moves in the thickness direction of the suction cup 600.

[0050] The control component 200 of the suction cup device of this utility model is rotatably connected to the housing 100 through the through hole 111. The control part 230 is exposed outside the housing 100 at least partially through the through hole 111. The through hole 111 is located on the side or above the side of the housing 100, rather than at the center of the top of the housing. This makes it less likely to interfere with the support body 700 or the linkage mechanism on the suction cup device, and it is convenient to use.

[0051] When the central region of the back of the suction cup 600 moves along the positive y-axis (in the direction indicated by the y-axis arrow), the central region is pulled, and the back of the suction cup 600 is pressed against the housing 100. When the central region of the back of the suction cup 600 moves along the negative y-axis (in the opposite direction of the y-axis arrow), the central region is pushed off, and the back of the suction cup 600 is released from the housing 100. When it is necessary to adsorb onto the surface of an object, the adsorption surface of the suction cup 600 is initially naturally adsorbed onto the surface of the object. By operating the control component 200, the central region of the back of the suction cup 600 moves along the positive y-axis (in the direction indicated by the y-axis arrow), and the back of the suction cup 600 is pressed against the housing 100 to form adsorption.

[0052] Specifically, the housing 100 includes two covers 110 and a base 120. The suction cup 300 is elastic and has an adsorption surface for adsorbing objects and a back surface opposite to the adsorption surface. The base 120 abuts against the back surface of the suction cup 300, and the driving mechanism 200 is connected to the central region of the back surface of the suction cup 300. The suction cup driving device 200 is used to drive the central region of the suction cup 300 to reciprocate relative to the housing 100 in the thickness direction of the suction cup.

[0053] Specifically, refer to Figure 4 and Figure 5 The control member 200 is used to drive the follower member 300 to move relative to the housing 100 toward the first side 101 or the second side 102, so that the suction cup 600 of the mobile phone holder switches to the suction state or the release state.

[0054] Specifically, initially, the follower 300 is in its initial position relative to the housing 100, and the suction cup 600 is in a released state. When the control member 200 drives the follower 300 to move relative to the housing 100, causing the follower 300 to move towards the first side 101 to a predetermined position, the suction cup 600 switches to an adsorption state, at which point the suction cup 600 is adsorbed onto the mounting surface. When the follower 300 is in its predetermined position relative to the housing 100, and the control member 200 drives the follower 300 to move relative to the housing 100, causing the follower 300 to move towards the second side 102 to its initial position, the suction cup 600 switches to a released state, at which point the suction cup 600 releases from the mounting surface, thus releasing its adsorption. The mounting surface includes a tabletop, tile surface, glass surface, or vehicle center console surface, etc.

[0055] Reference Figure 4 and Figure 5 The first side 101 and the second side 102 are respectively located on both sides of the housing 100 in a first direction. In the figure, the first direction is parallel to the direction indicated by arrow x.

[0056] like Figure 6 and Figure 7 As shown, the drive unit 220 includes a first pushing top 221; the drive unit 310 includes a first pushed top 320. The first pushing top 221 abuts against the first pushed top 320 to move the follower 300 relative to the housing 100 in a first direction. In one embodiment, the present application can perform unidirectional drive through the cooperation of the first pushing part and the first pushed part. The control member 200 pushes the follower 300 only inward toward the housing 100, and the follower 300 passively returns to its original position by the elastic force of the spring connected to it.

[0057] Furthermore, the drive unit 220 also includes a second push top 210, and the drive unit 310 also includes a second pushed top 301. The second push top 210 is used to abut against the second push top 210 to move the follower 300 relative to the housing 100 in a second direction, which is opposite to the first direction. In this embodiment, the follower 300 is driven bidirectionally by the cooperation of the first push part and the first pushed part, and by the cooperation of the second push part and the second pushed part. In addition to pushing the follower 300 inward toward the housing 100, the control member 200 can also pull the follower 300 outward by the cooperation of the second push part and the second pushed part. The first direction and the second direction are not necessarily perpendicular to the thickness direction. The second push top 210 is located at the end of the drive unit 310 away from the control unit 230.

[0058] Specifically, the top 210 of the second push is a linkage component. The linkage component can be a rod-shaped component or a structural component of any shape that can realize the display function.

[0059] A clearance area 2211 is provided between the linkage and the rotation axis of the control unit 230. The clearance area 2211 can be a region, a groove, or a hollow structure, as long as it has a partial clearance function. The rotation axis can be a fixed axis or a movable axis. The clearance area 2211 accommodates and clears the drive unit 310.

[0060] The first pushed top 320 and the second pushed top 301 are arranged opposite to each other, and the first pushed top 320 and the second pushed top 301 are connected by a bridging surface. The first pushed top 320 and the second pushed top 301 together with the bridging surface form a linkage groove 340, and the linkage component is inserted into the linkage groove 340.

[0061] The control member 200 is used to rotate relative to the housing 100, so that the linkage member 340 interacts with the linkage groove to drive the follower member 300 to move relative to the housing 100 toward the first side 101 or the second side 102.

[0062] like Figure 8 and Figure 9 As shown, the linkage groove 340 includes a first abutting inner wall 410 and abutting inner wall 420. The first abutting inner wall 410 and the second abutting inner wall 420 are disposed opposite each other in a direction parallel to the first direction. The first abutting inner wall 410 is closer to the first side 101 than the second abutting inner wall 420.

[0063] The linkage is used to abut against the first abutting inner wall 410 or the second abutting inner wall 420 to drive the follower 300 to move toward the first side 101 or the second side 102.

[0064] During the process of the linkage component engaging with the first abutting inner wall 410 or the second abutting inner wall 420, the contact and force transmission between the linkage component and the surface are realized, making the engagement between the first drive unit 210 and the second drive unit 301 more reliable and the force transmission more stable.

[0065] Furthermore, the linkage groove 340 also includes a closed end 430 and an open end 440, which are arranged opposite to each other in a direction parallel to the second direction. The second direction is parallel to the thickness direction of the housing 100 and perpendicular to the first direction. (Refer to...) Figure 4 , Figure 5 and Figure 9 The second direction is parallel to the direction indicated by the arrow y.

[0066] When assembling the control component 200 and the follower component 300, the linkage component can be inserted into the linkage groove 340 through the open end 440.

[0067] The control unit 230 is at least partially located outside the housing 100. For example... Figure 6As shown, the drive unit 210 and the control unit 230 can be an integrated structure.

[0068] like Figure 6 and Figure 10 As shown, the control component 200 is provided with a first adapter 222, and a protrusion is provided off-center inside the housing 100. The protrusion is provided with a second adapter 103 that is rotatably connected to the first adapter 222. Specifically, the protrusion can be integrally formed on the housing base 120 or integrally formed on the side wall of the housing cover 110. The first adapter 222 is rotatably connected to the second adapter 103 inside the housing 100 via a pivot.

[0069] Specifically, both the first adapter 222 and the second adapter 103 are provided with shaft holes, in which the rotating shaft is inserted into each shaft hole of the first adapter 222 and the second adapter 103, thereby connecting the first adapter 222 and the second adapter 103, thus realizing the rotational connection between the control member 200 and the housing 100.

[0070] Compared to the adapter 222, the drive unit 210 is further away from the control unit 230. This structure facilitates the installation between the drive unit 210 and the drive unit 301; in addition, when the user drives the control unit 230, since the drive unit 210 is further away from the control unit 230, the drive unit 210 can provide greater torque to drive the follower 300 to move, thereby achieving the effect of saving effort.

[0071] like Figure 6 As shown, there are two drive units 220, which are spaced apart and form a clearance area 2211 between them. The clearance area 2211 is used to accommodate the drive unit 310, which is at least partially movably disposed within the clearance area 2211.

[0072] There are also two push units 330, which are spaced apart and form a clearance space between them. The drive unit 310 is connected to the two push units 330 in a U-shape. The clearance space can accommodate the connecting platform 610 of the suction cup 600, making the overall structure more compact. Specifically, the drive unit 310 and the push units 330 are an integral structure.

[0073] The drive unit 310 is provided with a clearance part 321, which is used to accommodate and clear the transition unit 222. The clearance part 321 has a concave structure. By providing the clearance part 321, the overall structure of the suction cup drive device can be made more compact, thereby reducing the space occupied. In other embodiments, when there is enough space, the push unit 330 may not have the clearance part 321.

[0074] Specifically, the follower 300 drives the slave 500 to move the central region of the back of the suction cup 600 in the thickness direction of the suction cup 600.

[0075] like Figure 7 As shown, the follower 300 includes a first component 310, and a second drive component 301 is disposed on the first component 310, and the second drive component 301 cooperates with a corresponding first drive component 210. The second drive component 301 and the first component 310 can be an integral structure. Specifically, there are two second drive components 301, which are respectively disposed at both ends of the first component 310 in the length direction.

[0076] Reference Figure 6 , Figure 7 and Figure 11 The clearance area 2211 is used to accommodate the first component 310, which is at least partially movably disposed within the clearance area 2211, thereby maximizing the use of space and reducing the space occupied by the suction cup drive device.

[0077] like Figure 7 As shown, two pushing parts 320 are positioned on either side of the first component 310. One end of each pushing part 320 is connected to the first component 310, and the other end extends away from the first component 310. The pushing parts 320 can improve the structural strength of the first component 310 to a certain extent.

[0078] In this embodiment, the first component 310 and the pushing component 320 are an integral structure, with the two pushing components 320 positioned on opposite sides of the length of the first component 310. The integral structure of the first component 310 and the pushing component 320 reduces manufacturing costs and further enhances the structural strength of both components.

[0079] Wherein, both the first direction and the thickness direction of the housing 100 are perpendicular to the length direction of the first component 310. (Refer to...) Figure 7 The length direction of the first component 310 is parallel to the direction indicated by arrow z.

[0080] In this embodiment, the drive unit 210 and other structures (partial or all structures) on the control member 200 can be integrally formed, thereby further improving the structural strength of the drive unit 210; the drive unit 301 and other structures (partial or all structures) on the follower member 300 can be integrally formed, thereby further improving the structural strength of the drive unit 301.

[0081] like Figure 3As shown, in this embodiment, the suction cup driving device further includes a driven member 500 that cooperates with the follower 300. The suction cup 600 is connected to the driven member 500.

[0082] The movable direction of the follower 300 relative to the housing 100 is parallel to the first direction, and the movable direction of the driven member 500 relative to the housing 100 is parallel to the second direction.

[0083] like Figure 3 As shown, in this embodiment, the cover 110 and the base 120 of the housing 100 are detachably connected. The control unit 230 passes through the through hole 111 on the side of the cover 110 and extends out of the housing 100.

[0084] The follower 300 and the housing 120 can be connected by a slider and a groove, so that the follower 300 can only translate relative to the housing 120 in a direction parallel to the first direction.

[0085] like Figure 12 As shown, the driven member 500 includes a sliding body 510; as Figure 10 As shown, the housing 120 is provided with a sliding hole 121 along the thickness direction of the housing 100, wherein the sliding body 510 is slidably inserted into the sliding hole 121. The cooperation between the sliding body 510 and the sliding hole 121 allows the follower 500 to translate relative to the housing 120 only in a direction parallel to the second direction.

[0086] like Figure 12 As shown, the bottom of the sliding body 510 is provided with a mounting base 511, wherein the connecting platform 610 in the middle of the top surface of the suction cup 600 can be connected to the mounting base 511 by means of snap-fit, plug-in, screw connection, etc.

[0087] When assembling the follower 500 and the housing 120, the mounting base 511 enters and passes through the sliding hole 121, and then the suction cup 600 is mounted on the mounting base 511. The sliding body 510 is slidably connected to the sliding hole 121.

[0088] like Figure 10 As shown, the adapter part 103 is mounted on the housing 120. (Refer to...) Figure 4 and Figure 5 When the control member 200 rotates relative to the housing 100, the follower member 300 translates in a direction parallel to the first direction due to the cooperation between the linkage member and the linkage groove. When the follower member 300 translates, it drives the driven member 500 to translate in a direction parallel to the second direction.

[0089] like Figure 7As shown, the follower 300 includes a pushing part 330. The pushing part 330 is provided with two driving structures 331, wherein the driving structure 331 includes a protruding structure.

[0090] like Figure 12 and Figure 13 As shown, the driven member 500 includes a driven structure 520, which corresponds one-to-one with the driving structure 331. The driven structure 520 includes a first receiving cavity 521 and a second receiving cavity 522 arranged sequentially along a first direction, with the first receiving cavity 521 being farther from the through hole 111 and the operating member 200 than the second receiving cavity 522. Furthermore, in a direction parallel to the second direction, the first receiving cavity 521 is closer to the suction cup 600 than the second receiving cavity 522; moreover, the top of the first receiving cavity 521 is closer to the suction cup 600 than the top of the second receiving cavity 522. Figure 13 In the middle, the top of the first receiving cavity 521 and the second receiving cavity 522 are respectively the top of their respective cavities.

[0091] like Figure 13 As shown, in this embodiment, the second receiving cavity 522 includes a positioning surface 5221 and a guiding surface 5222 respectively disposed on both sides of the top of the second receiving cavity 522. The positioning surface 5221 is closer to the through hole 111 than the guiding surface 5222. Both the positioning surface 5221 and the guiding surface 5222 belong to the inner wall of the second receiving cavity 522. A corner portion 523 is provided between the first receiving cavity 521 and the guiding surface 5222. The corner portion 523 can protrude towards the side where the suction cup 600 is located. The inner wall of the first receiving cavity 521 and the guiding surface 5222 are both smoothly connected to the corner portion 523. The corner portion 523 includes an arc-shaped surface.

[0092] Reference Figure 13 The top end of the guide surface 5222 is connected to the top end of the corresponding second receiving cavity 522, and the bottom end of the guide surface 5222 is connected to the corresponding corner portion 523. Parallel to the second direction (i.e., Figure 13 (In the vertical direction) from the top to the bottom of the guide surface 5222, the vertical distance between the guide surface 5222 and the corresponding corner portion 523 gradually decreases.

[0093] like Figure 14 and Figure 15 As shown, when the suction cup 600 is in the released state, the suction cup 600 is in the natural state (no deformation occurs). At this time, the driving structure 331 of the follower 300 is located in the second receiving cavity 522 of the slave 500; wherein, the positioning surface 5221 is in contact with the corresponding driving structure 331 to play the role of positioning the driving structure 331.

[0094] When the suction cup 600 is in the adsorption state, the drive structure 331 of the follower 300 is located in the first receiving cavity 521 of the follower 500; the corner portion 523 achieves self-locking of the corresponding drive mechanism, so that the follower 300 can be stably embedded in the first receiving cavity 521 without the action of a certain external force, and will not automatically move from the first receiving cavity 521 into the second receiving cavity 522.

[0095] Suction cup 600 is in the released state:

[0096] Reference Figure 4 The suction cup 600 is pre-attached to the mounting surface, and a force is applied to the control member 200, causing the control member 200 to rotate relative to the housing 100. At this time, the rotation direction of the control member 200 is downward (i.e., Figure 4 Rotate the control element clockwise (indicating direction) until the control element 200 rotates to... Figure 5 The location shown;

[0097] Reference Figure 9 During the rotation of the control member 200, the linkage acts on the first abutting inner wall 410. Due to the constraint of the housing 100, under the action of the control member 200, the follower 300 moves relative to the housing 100 in a direction parallel to the first direction, while the position of the driven member 500 in the first direction remains unchanged; wherein, reference Figure 15 During the rotation of the control component 200, the follower component 300 translates horizontally to the left relative to the driven component 500;

[0098] Reference Figure 15 and Figure 16 When the follower 300 moves in a direction parallel to the first direction, the drive structure 331 on the follower 300 gradually moves out of the second receiving cavity 522 and moves along the guide surface 5222. After passing the corner portion 523, it enters the first receiving cavity 521. Finally, the top of the drive structure 331 is opposite to and in contact with the top of the first receiving cavity 521. (Refer to...) Figure 4 and Figure 5 From this perspective, during this process, the drive structure 331 will apply a component force parallel to the second direction to the follower 500, thereby causing the follower 500 to translate vertically upward relative to the housing 120. Correspondingly, the housing 120 translates vertically downward relative to the follower 500. In this way, the skirt 620 of the suction cup 600 is pressed by the housing 120, so that the skirt 620 of the suction cup 600 remains relatively fixed with the mounting surface.

[0099] The middle part of the suction cup 600 moves with the follower 500 (moving in the direction away from the mounting surface) and deforms. At this time, a vacuum cavity is formed between the central area of ​​the bottom surface of the suction cup 600 and the mounting surface, so the suction cup 600 enters the adsorption state. In this way, the suction cup 600 can be stably adsorbed on the mounting surface by negative pressure and the squeezing of the housing 120 on the suction cup 600.

[0100] The suction cup 600 is in the adsorption state:

[0101] Reference Figure 5 A force is applied to the control member 200, causing the control member 200 to rotate relative to the housing 100. At this time, the rotation direction of the control member 200 is upward (i.e., Figure 5 Rotate counterclockwise (indicating direction) until the control element 200 rotates to... Figure 4 The location shown;

[0102] Reference Figure 9 During the rotation of the control member 200, the linkage acts on the second abutting inner wall 420. Due to the constraint of the housing 100, under the action of the control member 200, the follower 300 moves relative to the housing 100 in a direction parallel to the first direction, while the position of the driven member 500 in the first direction remains unchanged; wherein, reference Figure 16 During the rotation of the control component 200, the follower component 300 translates horizontally to the right relative to the driven component 500.

[0103] Reference Figure 15 and Figure 16 When the follower 300 moves in a direction parallel to the first direction, the drive structure 331 on the follower 300 gradually moves out of the first receiving cavity 521, enters the second receiving cavity 522 after passing the corner portion 523, and then moves along the guide surface 5222. Finally, the top of the drive structure 331 is opposite to and in contact with the top of the second receiving cavity 522. During this process, the follower 500 moves vertically downward under the action of the return spring 524. Figure 16 (As shown in the orientation), the housing 120 moves toward the side away from the suction cup 600 and releases the pressure on the skirt 620; wherein, the middle part of the suction cup 600 moves with the follower 500, and the suction cup 600 returns to its natural state, thus releasing the suction cup 600 from adhering to the mounting surface.

[0104] like Figure 17 and Figure 18As shown, a return spring 524 is provided on the driven member 500, and one end of the return spring 524 is opposite to the inner top surface 112 of the housing cover 110 (facing the inner wall of the suction cup 600). When the suction cup 600 is in the suction state, the distance between the driven member 500 and the inner top surface 112 of the housing cover 110 is the smallest. At this time, the return spring 524 is squeezed by the inner top surface 112 of the housing and the driven member 500, and deforms.

[0105] like Figure 19 As shown, this embodiment also proposes a mobile phone holder, including the suction cup device described above and a support body 700 for connecting the mobile phone.

[0106] The support body 700 includes a mounting part 710, wherein the mounting part 710 is used to mount a mobile phone fixing device, such as a clamping mechanism or a magnetic suction mechanism.

[0107] In this embodiment, the mounting part 710 includes a ball head, wherein the mobile phone fixing device rotates on the ball head. In other embodiments, the mounting part 710 can be directly connected to a magnetic attraction mechanism, which cooperates with a magnetic ring or iron ring on the mobile phone case to achieve the installation of the mobile phone.

[0108] The support body 700 also includes a connecting arm 720, one end of which is connected to the mounting part 710 and the other end of which is connected to the housing 100.
