Description

Technical Field

[0001] This utility model relates to the field of mobile terminal brackets, and in particular to a suction cup bracket. Background Technology

[0002] With the widespread use of smartphones and other mobile devices, the frequency of use of various mobile applications is gradually increasing. To free up our hands for viewing mobile devices, mobile device stands have effectively solved this problem. Traditional mobile device stands are mechanical structures, which are stable but relatively complex, and it is also inconvenient to remove mobile devices. Therefore, magnetic stands have emerged.

[0003] Existing magnetic phone holders typically consist of a base and a support attached to the base. Magnetic attachments are mounted on the support to hold the phone. When in use, the base is placed directly on the support surface, which can lead to instability. To address this, suction cups are usually installed at the bottom of the base to attach the phone to the support surface. While this allows the phone to adhere, the lack of a design to adjust the suction cup's strength limits its effectiveness. Furthermore, the support typically cannot be folded and stored on the base, taking up considerable space when not in use.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a suction cup holder that can be easily folded and stored when not in use, saving space, and can adjust the suction power of the suction cup so that the suction cup can be firmly and tightly attached to the support surface.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A suction cup holder includes a base and a support seat disposed on the base for supporting a mobile terminal; a support member is disposed between the base and the support seat, one end of the support member is rotatably connected to the base, and one end of the support seat is rotatably connected to the other end of the support member;

[0008] As the support rotates relative to the base, the other end of the support moves closer to or further away from the base; as the support seat rotates relative to the support, the other end of the support seat moves closer to or further away from the support.

[0009] The base is provided with a rotating seat that can rotate relative to the base. A suction cup is provided at the end of the base away from the support member. A linkage member that can move relative to the base is provided on the base. One end of the linkage member is connected to the middle of the side of the suction cup near the base. The rotating seat is connected to the linkage member in a transmission manner.

[0010] Rotating the rotating seat drives the linkage to move, and the linkage moves the middle part of the suction cup relative to the peripheral edge of the suction cup, so that a negative pressure cavity is formed or the negative pressure cavity is canceled on the side of the suction cup away from the seat.

[0011] As a preferred embodiment, the support base is provided with a magnetic attachment for adsorbing mobile terminals.

[0012] As a preferred embodiment, one end of the support member is pivotally connected to the base body via a first pivot member, and one end of the support base is pivotally connected to the other end of the support member via a second pivot member.

[0013] As a preferred embodiment, the upper end of the base is provided with a turntable that can rotate relative to the base, and one end of the support member is rotatably connected to the turntable.

[0014] As a preferred embodiment, the upper end of the base is provided with a rotating part that protrudes upward, and the upper end of the rotating part is connected to a stop plate. The turntable is rotatably fitted onto the rotating part, and the upper end of the turntable is restricted by the lower end of the stop plate.

[0015] As a preferred embodiment, the seat includes a base and a base connected to the upper end of the base, a rotation space is formed between the base and the base, the rotating seat is rotatably mounted in the rotation space, the linkage is movable up and down between the base and the base, and the suction cup is disposed at the lower end of the base.

[0016] As a preferred embodiment, the lower end of the base is provided with a clearance groove, one end of the linkage is connected to the upper middle part of the suction cup via a connector, the connector and the middle part of the suction cup can move within the clearance groove, the peripheral edge of the suction cup is restricted by the lower end of the base, and the upper end of the connector passes through the base and is connected to the linkage.

[0017] As a preferred embodiment, the base and the pedestal are connected by two sets of connecting columns arranged at intervals, the linkage is constrained between the two sets of connecting columns, and the rotating seat is rotatably fitted onto the two sets of connecting columns.

[0018] As a preferred embodiment, the lower end of the base is provided with an annular guide portion, and the upper end of the rotating seat is provided with an annular guide groove, with the annular guide portion positioned within the annular guide groove.

[0019] As a preferred embodiment, the rotary seat is provided with a first threaded connection part, and the linkage is provided with a second threaded connection part, wherein the first threaded connection part and the second threaded connection part are rotatably connected by threads.

[0020] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves setting a support member between the base and the support seat, so that one end of the support member is rotatably connected to the base, and one end of the support seat is rotatably connected to the other end of the support member. In this way, as the support member rotates relative to the base, the other end of the support member moves closer to or away from the base, and as the support seat rotates relative to the support member, the other end of the support seat moves closer to or away from the support member. This allows the support member and the support seat to be stacked together on the base when not in use by rotating them, which is convenient for folding and storage and saves space.

[0021] Secondly, by setting a rotating seat that can rotate relative to the seat body, setting a suction cup at the end of the seat body away from the support member, and setting a linkage member that can move relative to the seat body, one end of the linkage member is connected to the middle of the side of the suction cup near the seat body. The rotating seat and the linkage member are connected in a transmission connection. In this way, by rotating the rotating seat, the rotating seat can drive the linkage member to move. The linkage member drives the middle of the suction cup to move relative to the peripheral edge of the suction cup, so that a negative pressure cavity is formed or the negative pressure cavity is canceled on the side of the suction cup away from the seat body. This allows the suction capacity of the suction cup to be adjusted, so that the suction cup can be firmly and tightly attached to the support surface through the negative pressure cavity, and the suction cup can be easily removed from the support surface by canceling the negative pressure cavity.

[0022] Furthermore, by providing a turntable that can rotate relative to the base, one end of the support member is rotatably connected to the turntable. Thus, after the base is attached to the support surface by a suction cup, rotating the turntable causes the support member and the support base to rotate as a whole, thereby facilitating the adjustment of the angle of the support base. This allows for the adjustment of the angle of the mobile terminal (such as a mobile phone) to meet the user's usage needs.

[0067] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inner", and "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model 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 utility model.

[0068] Please refer to Figures 1 to 11 As shown, it illustrates the specific structure of the suction cup holder provided in an embodiment of the present invention.

[0069] The suction cup holder includes a base and a support base 10 disposed on the base for supporting a mobile terminal. A support member 20 is disposed between the base and the support base 10. One end of the support member 20 is rotatably connected to the base, and one end of the support base 10 is rotatably connected to the other end of the support member 20. As the support member 20 rotates relative to the base, the other end of the support member 20 moves closer to or further away from the base. As the support base 10 rotates relative to the support member 20, the other end of the support base 10 moves closer to or further away from the support member 20. In this way, when not in use, the support member 20 and the support base 10 can be stacked together on the base by rotating them, which is convenient for folding and storage and saves space.

[0070] A rotating seat 30 is provided on the base body, which can rotate relative to the base body. A suction cup 40 is provided at the end of the base body away from the support member 20. A linkage member 50 is provided on the base body, which can move relative to the base body. One end of the linkage member 50 is connected to the middle part of the side of the suction cup 40 near the base body. The rotating seat 30 and the linkage member 50 are connected in a transmission manner. When the rotating seat 30 is rotated, the rotating seat 30 can drive the linkage member 50 to move. The linkage member 50 drives the middle part of the suction cup 40 to move relative to the peripheral edge of the suction cup 40, so that a negative pressure cavity is formed or the negative pressure cavity is canceled on the side of the suction cup 40 away from the base body. This allows the suction capacity of the suction cup 40 to be adjusted, so that the suction cup 40 can be firmly and tightly attached to the support surface through the negative pressure cavity, and the suction cup 40 can be easily removed from the support surface by canceling the negative pressure cavity. Specifically, when it is necessary to fix the suction cup bracket to the support surface, first attach the suction cup 40 to the support, and then drive the linkage 50 to move upward by rotating the rotating seat 30. The linkage 50 drives the middle part of the suction cup 40 to move upward, so as to increase the volume of the space between the suction cup 40 and the support surface, reduce the gas pressure in the space between the suction cup 40 and the support surface, and thus form a negative pressure state relative to the external atmosphere, that is, form a negative pressure cavity, so that the suction cup 40 can be stably attached to the support surface.

[0071] like Figures 3 to 6 As shown, the support base 10 is provided with a magnetic suction member 11 for adsorbing a mobile terminal. A first silicone pad 12 is provided on the side of the magnetic suction member 11 away from the support base 10. The first silicone pad 12 protrudes from the upper surface of the support base 10. In this way, when the mobile terminal is adsorbed onto the support base 10, the mobile terminal only contacts the first silicone pad 12, thereby preventing the mobile terminal from contacting the support base 10. Additionally, the upper surface of the support base 10 is recessed with a first positioning groove 13, and the bottom of the first positioning groove 13 is recessed with an annular positioning groove 14. The magnetic suction member 11 is an annular magnet assembly with a notch. The annular magnet assembly is installed in the annular positioning groove 14. The first silicone pad 12 is assembled in the first positioning groove 13, so that the upper surface of the first silicone pad 12 protrudes outside the first positioning groove 13. The lower surface of the support base 10 is recessed with a second positioning groove 15. The inner top wall of the second positioning groove 15 is provided with a first cavity 16. The weight and material usage of the support base 10 can be reduced through the first cavity 16. The second positioning groove 15 is equipped with a second silicone pad 17.

[0072] like Figure 5 and Figure 6As shown, the support member 20 has a ring-shaped structure. One end of the support member 20 is pivotally connected to the base body via a first pivot member 21, and one end of the support base 10 is pivotally connected to the other end of the support member 20 via a second pivot member 22. Specifically, a turntable 60 that can rotate relative to the base body is provided at the upper end of the base body. One end of the support member 20 is rotatably connected to the turntable 60. The two ends of the first pivot member 21 are respectively connected to one end of the support member 20 and the turntable 60. One end of the support member 20 has a first pivot portion 23, and the turntable 60 has a second pivot portion 61. The first pivot portion 23 and the second pivot portion 61 are pivotally connected via the first pivot member 21. The other end of the support member 20 has a third pivot portion 24, and one end of the support base 10 has a fourth pivot portion 18. The third pivot portion 24 and the fourth pivot portion 18 are pivotally connected via the second pivot member 22.

[0073] like Figures 3 to 6 As shown, the upper end of the base is provided with a rotating part 81 protruding upwards. The upper end of the rotating part 81 is connected to a stop plate part 101. The turntable 60 is rotatably sleeved on the rotating part 81. The upper end of the turntable 60 is restricted by the lower end of the stop plate part 101, and the lower end of the turntable 60 is restricted by the upper end of the base, so as to restrict the movement of the turntable 60 in the axial direction. The rotating part 81 has a first connecting hole 811, and the stop plate part 101 has a second connecting hole 1011. The first connecting hole 811 and the second connecting hole 1011 are locked together by screws.

[0074] like Figure 5 and Figure 6 As shown, the upper and lower surfaces of the turntable 60 are respectively recessed with a first clearance groove 62 and a second clearance groove 63. The turntable 60 has a through hole 64, the upper and lower ends of which are connected to the first clearance groove 62 and the second clearance groove 63 respectively. The axes of the through hole 64, the first clearance groove 62, and the second clearance groove 63 coincide. The upper end of the rotating part 81 passes through the through hole 64 and protrudes into the first clearance groove 62. The stop plate part 101 is positioned in the first clearance groove 62. The bottom of the first clearance groove 62 is restricted by the lower end of the stop plate part 101. The upper surface of the stop plate part 101 is covered with a third silicone pad 102. An annular washer 103 is sleeved on the lower end of the rotating part 81. The lower end of the annular washer 103 abuts against the upper end of the seat. The annular washer 103 is positioned in the second relief groove 63, and the lower end of the annular washer 103 protrudes from the lower surface of the turntable 60. In this way, when the turntable 60 is rotated, the contact between the turntable 60 and the seat can be reduced, thereby reducing wear. In addition, a second cavity 65 is provided on the lower surface of the turntable 60 around the second relief groove 63. The second cavity 65 can reduce the weight and material usage of the turntable 60, and further reduce the contact between the turntable 60 and the seat.

[0075] like Figures 3 to 8As shown, the base includes a base 70 and a base 80 connected to the upper end of the base 70. A rotation space is formed between the base 70 and the base 80. A rotating seat 30 is rotatably mounted in the rotation space. The upper and lower ends of the rotating seat 30 are respectively restricted by the lower end of the base 80 and the upper end of the base 70. A linkage 50 is located between the base 70 and the base 80 and can move up and down. A suction cup 40 is disposed at the lower end of the base 70. A rotating part 81 is formed at the upper end of the base 80. The lower end of the turntable 60 is restricted by the base 80. The upper end of the annular washer 103 abuts against the upper end of the base 80; and the periphery of the suction cup 40 is integrally provided with an extension protrusion 44, which extends horizontally outward from the base 70. A gap is left between the lower end face of the extension protrusion 44 and the plane where the lower end face of the suction cup 40 is located, so that when the suction cup 40 is adsorbed on the support surface, the extension protrusion 44 and the support surface maintain a gap, which is conducive to the subsequent insertion into the gap and acting on the extension protrusion 44 to better remove the suction cup 40 from the support surface.

[0076] like Figures 3 to 8 As shown, the lower end of the base 70 is provided with a clearance groove 71. One end of the linkage 50 is connected to the upper middle part of the suction cup 40 via a connector 90. The connector 90 and the middle part of the suction cup 40 can move within the clearance groove 71. The peripheral edge of the suction cup 40 is restricted by the lower end of the base 70. The upper end of the connector 90 passes through the base 70 and is connected to the linkage 50. Specifically, the upper end of the connector 90 is provided with a positioning post 91, which has a first positioning hole 911. The base 70 has a through hole 72. The linkage 50 is a sliding block, which has a second positioning hole 51. The positioning post 91 passes through the through hole 72 and extends into the second positioning hole 51. The second positioning hole 51 and the first positioning hole 911 are locked together by screws. The lower surface of the linkage 50 is provided with a third cavity 52. ​​The third cavity 52 can reduce the weight and material usage of the linkage 50. The lower end of the connector 90 is provided with a snap-fit ​​post 92, and the upper middle part of the suction cup 40 is provided with a third positioning groove 41. The bottom of the third positioning groove 41 is provided with a snap-fit ​​hole 42. The snap-fit ​​post 92 snaps into the snap-fit ​​hole 42 and is fixed by applying glue. The outer periphery of the third positioning groove 41 is formed with an annular covering protrusion 43, which covers the outer periphery of the connector 90 and is fixed by applying glue. In this way, the linkage 50, the connector 90 and the suction cup 40 are firmly connected.

[0077] like Figures 3 to 8As shown, the base 70 and the base 80 are connected by two sets of connecting columns arranged at intervals. The linkage 50 is constrained between the two sets of connecting columns, and the rotating seat 30 is rotatably sleeved on the two sets of connecting columns. Specifically, one or two opposite sidewalls of the linkage 50 in the circumferential direction are planar structures. Each set of connecting columns includes two first connecting columns 82 and two second connecting columns 73. The two first connecting columns 82 are spaced apart at the lower end of the base 80 and connected by connecting walls 83. The two second connecting columns 73 are spaced apart at the upper end of the base 70. The first connecting column 82 has a third connecting hole 821 that extends to the upper surface of the base 80. The second connecting column 73 has a fourth connecting hole 731 that extends into the third connecting hole 821. The third connecting hole 821 and the fourth connecting hole 731 are fastened together by screws. One or two opposite sidewalls of the linkage 50 in the circumferential direction are respectively constrained by the corresponding connecting walls 83.

[0078] like Figures 3 to 8 As shown, the lower end of the base 80 is provided with an annular guide portion 84, which is located around the first connecting column 82. The upper end of the rotating seat 30 is provided with an annular guide groove 31, and the annular guide portion 84 is positioned within the annular guide groove 31. The lower surface of the annular guide portion 84 is provided with a contact strip 841, which allows the annular guide portion 84 and the annular guide groove 31 to contact each other through the contact strip 841. This reduces the contact area between the two, reduces friction during relative rotation, and makes the rotation smoother and easier to operate. The contact strip 841 is preferably a ring-shaped rib. Furthermore, the upper end of the base 80 is provided with a fourth cavity portion 85, which can reduce the weight and material usage of the base 80.

[0079] The upper end of the rotating base 30 is recessed with a receiving cavity 32, and an annular guide groove 31 is provided at the inner bottom of the receiving cavity 32. The base 80 and the turntable 60 are both located inside the receiving cavity 32 to cover the periphery of the base 80 and the turntable 60, making the appearance more aesthetically pleasing. The lower end of the rotating base 30 is provided with a first annular cavity 33 and a second annular cavity 34 arranged radially from the inside to the outside. A first annular contact portion 35 is provided between the first annular cavity 33 and the second annular cavity 34. The periphery of the second annular cavity 34 is provided with... The base 70 has a second annular contact portion 36. The lower ends of the first annular contact portion 35 and the second annular contact portion 36 are restricted by the upper end of the base 70, so that the rotating seat 30 and the base 70 can be in contact through the first annular contact portion 35 and the second annular contact portion 36. This can reduce the contact area between the two, reduce friction during relative rotation, make the rotation smoother, and make the operation convenient. In addition, the upper end of the base 70 is provided with a fifth cavity portion 74. The fifth cavity portion 74 can reduce the weight and material usage of the base 70.

[0080] The rotating seat 30 is provided with a first threaded connection part 37, and the linkage 50 is provided with a second threaded connection part 53. The first threaded connection part 37 and the second threaded connection part 53 are threadedly rotatably connected. The rotating seat 30 is provided with a rotating hole 38 in the middle. The rotating hole 38 extends downward from the bottom of the receiving cavity 32 to the lower end of the rotating seat 30. The annular guide groove 31 is provided on the upper periphery of the rotating hole 38. The first annular cavity 33 is provided on the lower periphery of the rotating hole 38. The two sets of connecting column groups and the linkage 50 are all located in the rotating hole 38. The first threaded connection part 37 is formed on the inner peripheral sidewall of the rotating hole 38. The other two opposite sidewalls in the circumferential direction of the linkage 50 are arc-shaped structures. The other two opposite sidewalls in the circumferential direction of the linkage 50 extend out of the connecting column group. The other two opposite sidewalls in the circumferential direction of the linkage 50 are provided with second threaded connection parts 53.

[0081] In summary, the key design feature of this utility model lies in its use of a support member between the base and the support seat. One end of the support member is rotatably connected to the base, and one end of the support seat is rotatably connected to the other end of the support member. Thus, as the support member rotates relative to the base, its other end moves closer to or further away from the base; similarly, as the support seat rotates relative to the support member, its other end moves closer to or further away from the support member. This allows the support member and support seat to be stacked together on the base when not in use, facilitating folding and storage and saving space. Secondly, the design incorporates a rotating base that can rotate relative to the base, a suction cup at the end of the base away from the support member, and a moving linkage on the base. One end of the linkage is connected to the middle of the suction cup near the base. The rotating base is connected to the linkage mechanism. By rotating the rotating base, the rotating base drives the linkage mechanism to move. The linkage mechanism moves the center of the suction cup relative to the peripheral edge of the suction cup, so that a negative pressure chamber is formed or eliminated on the side of the suction cup away from the base. This allows adjustment of the suction cup's adsorption capacity, enabling the suction cup to be firmly and tightly adsorbed onto the support surface through the negative pressure chamber, and making it easy to remove the suction cup from the support surface by eliminating the negative pressure chamber. Furthermore, by providing a turntable that can rotate relative to the base, one end of the support component is rotatably connected to the turntable. Thus, after the base is adsorbed onto the support surface by the suction cup, rotating the turntable causes the support component and the support base as a whole to rotate, thereby facilitating adjustment of the angle of the support base. This allows adjustment of the angle of the mobile terminal (such as a mobile phone) to meet the user's usage needs.

[0082] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
