[0001] This utility model relates to the field of bracket technology, and in particular to an adjustable suction cup bracket. Background Technology

[0002] Suction cup holders are primarily used in automotive and other similar environments to support and secure electronic devices such as mobile phones and tablets. Existing suction cup holders generally employ a pull-up valve or lever-based suction mechanism, resulting in short-lived negative pressure maintenance. Furthermore, because the suction force of the suction cup is directly proportional to the operating force, it is difficult for women or those using only one hand to operate. In addition, most suction cup holders use ball joint locking or knob pressure plates for angle adjustment, requiring both hands and multiple tightening and loosening operations, posing a safety hazard while driving.

They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0017] Reference Figures 1 to 5As shown, this utility model provides an adjustable suction cup bracket, including a fixed base 1, a gear assembly 2 rotatably connected to the fixed base 1, a fixed suction cup 3 disposed at the bottom of the fixed base 1, a lead screw 4 connecting the fixed suction cup 3 and the gear assembly 2, a magnetic suction cup 5 disposed above the fixed base 1, and an angle adjustment mechanism 6 connecting the magnetic suction cup 5 and the fixed base 1; the gear assembly 2 is used to adjust the tightness of the magnetic suction cup 3's attraction to the external object via the lead screw 4; the magnetic suction cup 5 is used to support and fix the product, and the angle adjustment mechanism 6 is used to adjust the operating angle of the magnetic suction cup 5. Specifically, the fixed suction cup 3 is a silicone suction cup. The fixed suction cup 3 and the lead screw 4 are integrally molded by in-mold injection molding.

[0018] The adjustable suction cup holder provided by this utility model allows products (such as mobile phones, tablets, etc.) to be placed on the front of the magnetic suction cup 5 for support and fixation in practical applications.

[0019] The gear assembly 2 includes a knob ring 21 sleeved on the outer periphery of the fixed base 1, an internal gear 22 circumferentially disposed on the inner sidewall of the knob ring 21, a first gear 23 threadedly engaged with the lead screw 4, and a second gear 24 meshing between the internal gear 22 and the first gear 23. The first gear 23 has a through-hole in its middle, through which the upper part of the lead screw 4 passes and threadedly engages with the first gear 23. The bottom end of the lead screw 4 is fixedly connected to the top of the fixed suction cup 3. The internal gear 22-second gear 24-first gear 23 form a three-stage reduction, amplifying the torque of the rotating ring 21 several times. By rotating the knob ring 21 a few times, a negative pressure can be generated between the bottom of the fixed suction cup 3 and the outside.

[0020] The angle adjustment mechanism 6 includes a panel 61 rotatably mounted on top of the knob ring 21, a first hinge seat 62 mounted on top of the panel 61, a second hinge seat 63 mounted on the back of the magnetic chuck 5, and a central shaft 64 connecting the first hinge seat 62 and the second hinge seat 63. One end of the first hinge seat 62 is connected to the central shaft 64 via a first hinge shaft, and the other end of the second hinge seat 63 is connected to the central shaft 64 via a second hinge shaft. Multi-dimensional adjustment of the operating angle is achieved through the first / second hinge shafts, the central shaft 64, and the panel 61. By setting the first / second hinge seats 62 / 63, the first / second hinge shafts, and the central shaft 64, and in conjunction with the structure of the magnetic chuck 5 and the panel 61, a Z-shaped folding arm is formed, resulting in a small overall thickness when the bracket is folded away. In one specific embodiment, by connecting the first hinge shaft to the first hinge seat 62 and the second hinge shaft to the second hinge seat 63, the magnetic chuck 5 can be adjusted to pitch ±90°, and by rotating the panel 61, the magnetic chuck 5 can be hovered horizontally at 360° without limit. Simultaneously, damping elastic elements are provided between the first hinge seat 62 and the first hinge shaft, and between the second hinge seat 63 and the second hinge shaft, to achieve self-locking at any angle.

[0021] The fixing base 1 includes a fixing upper base 11, a fixing lower base 12 disposed below the fixing upper base 11, and a connecting column 13 connecting the fixing upper base 11 and the fixing lower base 12; the first gear 23 is disposed inside the connecting column 13; the side wall of the connecting column 13 has an opening for the first gear 23 and the second gear 24 to mesh and connect; the panel 61 is fastened to the fixing upper base 11. Furthermore, the fixing upper base 11 is configured as a ring structure, which is sleeved on the outer circumference of the connecting column 13, and the top of the fixing upper base 11 is substantially flush with the top of the connecting column 13.

[0022] In the fixed base 1, both the upper fixed base 11 and the lower fixed base 12 are fastened to the connecting column 13 with screws. The panel 61 of the angle adjustment mechanism 6 is locked to the upper fixed base 11 by a snap-fit. It is worth mentioning that the snap-fit ​​only restricts the panel 61 from moving up and down relative to the upper fixed base 11, but the panel 61 can rotate relative to the upper fixed base 11, thus not affecting its rotational horizontal adjustment angle. The lower fixed base 12, the knob ring 21, and the panel 61 form a closed receiving cavity. The internal gear 22, the first gear 23, the second gear 24, and the lead screw 4 are all located in this receiving cavity, avoiding the exposure of precision parts such as gears and lead screw 4, and effectively preventing abnormal noise or even jamming.

[0023] The top of the fixed base 1 is provided with a damping hemispherical head 7, and the bottom of the panel 61 is provided with several damping grooves corresponding to the damping hemispherical head 7. The several damping grooves are arranged in a circumferential manner, so that the damping hemispherical head 7 can slide into the several damping grooves one by one when the panel 61 rotates. An elastic element is also provided between the damping hemispherical head 7 and the fixed base 1. Specifically, the damping hemispherical head 7 is a metal part, including a hemispherical part and a connecting rod part provided at the bottom of the hemispherical part. The connecting rod part is movably inserted into the connecting post 13, and the elastic element is sleeved on the outer circumference of the connecting rod part. The elastic element is a spring. By setting the damping hemispherical head 7 to cooperate with the several damping grooves, when the panel 61 is rotated, the damping grooves around the bottom of the panel 61 slide past the damping hemispherical head 7 in sequence, making a "click" sound.

[0024] A limiting plate 8 is provided between the fixed base 1 and the lead screw 4; the end of the limiting plate 8 is detachably connected to the fixed base 1; at least one limiting groove is provided on the outer side wall of the lead screw 4, and a limiting protrusion 81 is provided on the limiting plate 8 corresponding to each limiting groove; the limiting protrusion 81 is inserted into the limiting groove, so that the lead screw 4 cannot rotate relative to the fixed base 1. Further, the limiting plate 8 includes a limiting ring in the middle and a limiting rod on each of the two opposite outer sides of the limiting ring; the limiting ring is sleeved on the outer circumference of the lead screw 4 and located at the bottom of the first gear 23, and the free end of each limiting rod is detachably connected to the fixed lower base 12 by a screw.

[0025] In one specific embodiment, rotating the knob ring 21 counterclockwise drives the first gear 23 through the internal gear 22 and the second gear 24. Under the limiting action of the limiting plate 8, the lead screw 4 can only move upward and cannot rotate, thereby lifting the middle part of the fixed suction cup 3 upward, so that a negative pressure is generated between the bottom of the fixed suction cup 3 and the outside.

[0026] In addition, the cross-section of the lead screw 4 is inverted T-shaped; the inverted T-shaped horizontal end of the lead screw 4 is fixed to the top of the fixed suction cup 3.
