Description

Technical Field

[0001] This utility model relates to the field of electronic device bracket technology, and in particular to a suction cup structure and bracket device. Background Technology

[0002] With the widespread use of smart terminal devices (such as smartphones and navigation devices) while driving, car suction cup mounts have become an essential car accessory for many car owners due to their ease of installation.

[0003] The suction cups of car suction cup holders are usually made of elastic polymer materials such as rubber and silicone. In the summer, the interior environment of the car is high. These materials are prone to aging or even deformation under long-term high temperature conditions, which leads to a decrease in the sealing performance between the suction cup and the contact surface. They cannot maintain sufficient adsorption force, resulting in the suction cup falling off and the holder failing.

[0004] Existing vehicle suction cup brackets have the suction cup and base as a single unit. Once the suction cup fails, it cannot be replaced separately, and the entire bracket base and even the entire vehicle bracket will become unusable. Utility Model Content

[0005] This utility model provides a suction cup structure to solve the problem that existing vehicle suction cup brackets have the suction cup and base as an integrated structure, and once the suction cup fails, the entire bracket base and even the entire vehicle bracket will lose their usability because the suction cup cannot be replaced separately.

[0006] This utility model discloses a suction cup structure, including: a base and a suction cup; the base is provided with a locking mechanism and a lifting mechanism; the suction cup is located at the bottom of the base and includes a skirt made of soft rubber, a protrusion extending integrally from the soft rubber in the central area of ​​the skirt, and a connecting part with one end embedded in the protrusion and the other end extending into the base, the connecting part being detachably connected to the lifting mechanism through the locking mechanism; the lifting mechanism includes a control part and a lifting part, the lifting part being movably connected to the base and capable of displacement along the thickness direction of the base, the control part being able to directly or indirectly drive the lifting part to reciprocate along the thickness direction of the base, thereby controlling the suction cup to vacuum connect or de-vacuum connect with the suction surface through the connecting part; the locking mechanism includes a connecting structure and a control structure; the connecting structure includes a first snap-fit ​​part and a second snap-fit ​​part that can be interconnected, wherein the first snap-fit ​​part is located on the connecting part, the second snap-fit ​​part...

The control structure has a first state and a second state. When the control structure is in the first state, the first latching part and the second latching part are in a locked state, which causes the relative position of the connecting part and the lifting part in the thickness direction of the base to be locked, so that the suction cup is not detachable relative to the base; when the control structure is in the second state, the first latching part and the second latching part are in an unlocked state, which causes the relative position of the connecting part and the lifting mechanism in the thickness direction of the base to be unlocked, so that the suction cup is detachable relative to the base. When the lifting part moves in the thickness direction of the base, the second latching part moves relative to the control structure in the moving direction.

[0007] Optionally, the control structure includes a pressing part and a driving part. The pressing part is at least partially exposed outside the base for external force to drive it. The driving part is disposed inside the base and is drivenly connected to the connecting structure to drive the first locking part and the second locking part to lock or unlock. One of the first locking part and the second locking part includes a locking protrusion, and the other includes a locking groove that engages with the locking protrusion. When the first locking part and the second locking part are in a locked state, the locking protrusion engages with the locking groove. When the first locking part and the second locking part are in an unlocked state, the locking protrusion can slide out of the locking groove.

[0008] Optionally, at least a portion of the protrusion is arc-shaped, and at least a portion of the slot is annular. When the protrusion is engaged in the slot, the connecting part and the lifting part can rotate relative to each other, so that the base can rotate relative to the suction cup.

[0009] Optionally, a rotation limiting structure is provided between the suction cup and the base to provide damping or positioning when the base rotates relative to the suction cup. The rotation limiting structure includes a first limiting part disposed on the connecting part or the protrusion and a second limiting part disposed on the lifting part; or, the rotation limiting structure includes a first limiting part disposed on the skirt and a second limiting part disposed on the base. Multiple first and second limiting parts are provided and arranged in a circumferential array to form a ring-shaped arrangement, while the other is an abutting structure that cooperates with the ring-shaped arrangement. The first and second limiting parts can form an abutting engagement at multiple angular positions to achieve damped or positioned rotational adjustment of the suction cup relative to the base. One of the first and second limiting parts includes a protrusion, and the other includes a groove that cooperates with the protrusion.

[0010] Optionally, the control structure further includes a sliding part, and the pressing part and the driving part are both connected to the sliding part; the base is provided with a sliding joint for the sliding part to slide and connect, and the side of the base is also provided with an opening, through which the pressing part protrudes for external force to drive; the driving part is driven to connect with the second locking part; the driving part includes a first pushing part; the second locking part is movably disposed on the lifting part; the second locking part includes a second pushing part that cooperates with the first pushing part; the first pushing part and the second pushing part movably abut against each other to cause the locking protrusion to move in the direction of disengaging from the locking groove.

[0011] Optionally, the driving part further includes a third pushing part, and the second locking part includes a fourth pushing part that cooperates with the third pushing part. The third pushing part and the fourth pushing part movably abut against each other to cause the locking protrusion to move in the direction of entering the locking groove.

[0012] Optionally, the base is further provided with a first elastic reset member, one end of which is connected to the base and the other end is connected to the pressing part, or the other end is connected to the second snap-fit ​​part. The first elastic reset member is used to drive the snap-fit ​​protrusion to move along the direction of entering the snap-fit ​​groove.

[0013] Optionally, a second elastic reset member is provided between the lifting part and the base. The lifting part is also provided with a movable block. The second limiting part is a protrusion on the movable block facing the suction cup. The side of the lifting part opposite to the protrusion abuts against the second elastic reset member. One end of the second elastic reset member acts on the movable block so that the protrusion abuts against the annular alignment structure, and the other end is connected to the base.

[0014] Optionally, the control unit is a lever connected to the base in a swinging direction along the thickness direction. One end of the lever is directly or indirectly connected to the lifting unit to drive the lifting unit to reciprocate along the thickness direction of the base, and the other end is exposed on the base for operation by external force. Alternatively, the control unit is a rotating component connected to the base in a rotating manner and rotatable relative to the base along the axial direction of the suction cup. The rotating component is directly or indirectly connected to the lifting unit to drive the lifting unit to reciprocate along the thickness direction of the base, and at least part of the rotating unit is exposed on the base for operation by external force.

[0015] This utility model also discloses a support device, including the suction cup structure described above.

[0016] The beneficial effects of the suction cup structure and support device provided in this embodiment are as follows: The suction cup in this embodiment is installed at the bottom of the base. A protrusion is provided in the central area of ​​the suction cup skirt. The protrusion is used to embed the connecting part. The connecting part is the key to realizing the detachable connection between the suction cup and the lifting mechanism through the locking mechanism. Specifically, the lifting mechanism consists of a control part and a lifting part. The lifting part is movably connected to the base and can move along the thickness direction of the base. The control part can directly or indirectly drive the lifting part to reciprocate along the thickness direction of the base. When suction cup adsorption is required, the control part drives the lifting part to move, and the connecting part drives the suction cup to expel the air between the suction cup and the adsorbed surface, forming a vacuum environment to achieve stable adsorption. When adsorption needs to be released, the control part drives the lifting part in the opposite direction to break the vacuum environment. The suction cup detaches from the surface it is attached to. The locking mechanism includes a connecting structure and a control structure. The control structure is mounted on the base, and its core function is to switch the first and second locking parts between different states. The control structure has two key states: a first state and a second state. When the control structure is in the first state, the first and second locking parts are locked, which fixes the relative positions of the connecting part and the lifting part in the thickness direction of the base, making the suction cup non-removable from the base and ensuring the stability of the suction cup during normal use. When the control structure switches to the second state, the locking state of the first and second locking parts is released, and the relative positions of the connecting part and the lifting mechanism in the thickness direction of the base are no longer locked. At this time, the suction cup can be disassembled relative to the base. In addition, as the lifting part moves along the thickness direction of the base, the second locking part moves synchronously with the control structure in the direction of movement, ensuring that the actions of the locking mechanism and the lifting mechanism are coordinated. In this embodiment, the suction cup is detachably connected to the lifting mechanism via a connecting part. When the locking mechanism is in the second state, the malfunctioning suction cup can be easily removed from the base. After replacing the suction cup with a new one, the base, lifting mechanism, locking mechanism, and other components can still be used, greatly reducing the user's operating costs and avoiding waste of resources.

Detailed Implementation

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] This utility model embodiment provides a suction cup structure 100 and a support device, such as Figures 1 to 10As shown, it includes: a base 10 and a suction cup 20; the base 10 is provided with a locking mechanism 50 and a lifting mechanism 40; the suction cup 20 is located at the bottom of the base 10 and includes a skirt 210 made of soft rubber, a protrusion 220 extending integrally from soft rubber in the central area of ​​the skirt 210, and a connecting part 230 with one end embedded in the protrusion 220 and the other end extending into the base 10, the connecting part 230 being detachably connected to the lifting mechanism 40 through the locking mechanism 50; the lifting mechanism 40 includes a control part 410 and a lifting part 420, which lift... The lifting part 420 is movably connected to the base 10 and can move along the thickness direction of the base 10. The control part 410 can directly or indirectly drive the lifting part 420 to reciprocate along the thickness direction of the base 10, thereby controlling the suction cup 20 to vacuum connect or disconnect from the suction surface through the connecting part 230. The locking mechanism 50 includes a connecting structure and a control structure 520. The connecting structure includes a first locking part 231 and a second locking part 511 that can be connected to each other, wherein the first locking part 231 is disposed on the connecting part 230. The second latching part 511 is disposed on the lifting part 420, and both can reciprocate along the thickness direction of the base 10 with the lifting part 420. The control structure 520 is disposed on the base 10 and is used to switch the connection state of the first latching part 231 and the second latching part 511. The control structure 520 has a first state and a second state. When the control structure 520 is in the first state, the first latching part 231 and the second latching part 511 are locked, which causes the relative position of the connecting part 230 and the lifting part 420 in the thickness direction of the base 10 to be locked, so that the suction cup 20 is not detachable from the base 10. When the control structure 520 is in the second state, the first latching part 231 and the second latching part 511 are unlocked, which causes the relative position of the connecting part 230 and the lifting mechanism 40 in the thickness direction of the base 10 to be unlocked, so that the suction cup 20 is detachable from the base 10. When the lifting part 420 moves in the thickness direction of the base 10, the second latching part 511 moves relative to the control structure 520 in the moving direction.

[0032] In this embodiment, the suction cup 20 is installed at the bottom of the base 10. A protrusion 220 is provided in the central area of ​​the skirt 210 of the suction cup 20. The protrusion 220 is used to embed the connecting part 230. The connecting part 230 is key to enabling the suction cup 20 to be detachably connected to the lifting mechanism 40 via the locking mechanism 50. Specifically, the lifting mechanism 40 consists of a control unit 410 and a lifting part 420. The lifting part 420 is movably connected to the base 10 and can move along the thickness direction of the base 10. The control unit 410 can directly or indirectly drive the lifting part 420 to reciprocate along the thickness direction of the base 10. When the suction cup 20 needs to be adsorbed, the control unit 410 drives the lifting part 420 to move, and the connecting part 230 drives the suction cup 20 to expel the air between the suction cup 20 and the adsorbed surface, forming a vacuum environment for stable adsorption. When adsorption needs to be released, the control unit 410 reverses the drive of the lifting part 420 to break the vacuum environment, facilitating the suction cup 20 to detach from the adsorbed surface. The locking mechanism 50 includes a connecting structure and a control structure 520. The control structure 520 is mounted on the base 10, and its core function is to switch the first latching part 231 and the second latching part 511 between different states. The control structure 520 has two key states, namely the first state and the second state. When the control structure 520 is in the first state, the first latching part 231 and the second latching part 511 are locked. This locking state fixes the relative position of the connecting part 230 and the lifting part 420 in the thickness direction of the base 10, thereby making the suction cup 20 non-removable from the base 10 and ensuring the stability of the suction cup 20 during normal use. When the control structure 520 switches to the second state, the locking state of the first latching part 231 and the second latching part 511 is released, and the relative position of the connecting part 230 and the lifting mechanism 40 in the thickness direction of the base 10 is no longer locked. At this time, the suction cup 20 can be disassembled relative to the base 10. Furthermore, as the lifting part 420 moves along the thickness direction of the base 10, the second locking part 511 moves synchronously with the control structure 520 in the moving direction, ensuring that the locking mechanism 50 and the lifting mechanism 40 move in unison. In this embodiment, the suction cup 20 is detachably connected to the lifting mechanism 40 via the connecting part 230. When the locking mechanism 50 is in the second state, the faulty suction cup 20 can be easily removed from the base 10. After replacing the suction cup 20, other components such as the base 10, lifting mechanism 40, and locking mechanism 50 can still be used, greatly reducing the user's operating costs and avoiding waste of resources.

[0033] In this embodiment, the base 10 is a shell structure with a receiving cavity, as shown in the reference. Figures 1 to 4 The bottom of the base 10 is located on the side below when in use.

[0034] As a preferred embodiment, refer to Figures 1 to 4The control structure 520 includes a pressing part 521 and a driving part 522. The pressing part 521 is at least partially exposed outside the base 10 for external force to drive it. The driving part 522 is located inside the base 10 and is driven to connect with the connecting structure to lock or unlock the first locking part 231 and the second locking part 511. One of the first locking part 231 and the second locking part 511 includes a locking protrusion 5111, and the other includes a locking groove 2311 that engages with the locking protrusion 5111. When the first locking part 231 and the second locking part 511 are in the locked state, the locking protrusion 5111 engages with the locking groove 2311. When the first locking part 231 and the second locking part 511 are in the unlocked state, the locking protrusion 5111 can slide out of the locking groove 2311.

[0035] The exposed design of the pressing part 521 makes the operation more convenient and direct for users. Users only need to press the pressing part 521 with their hands to control the locking and unlocking of the first locking part 231 and the second locking part 511 through the driving part 522. Compared with the complicated operation method, it greatly simplifies the user's operation process and improves the user experience.

[0036] The suction cup 20 employs a snap-fit ​​connection using a protrusion 5111 and a slot 2311, resulting in a simple structure and reliable connection. In the locked state, the protrusion 5111 is tightly engaged in the slot 2311, effectively withstanding a certain amount of external force. This prevents the first and second snap-fit ​​parts 231 and 511 from accidentally disengaging due to vibration or other factors during use, ensuring the stability of the connection between the suction cup 20 and the base 10 and further reducing the risk of the suction cup 20 falling off. In the unlocked state, the protrusion 5111 can slide out of the slot 2311, at which point the relative movement between the connecting part 230 and the lifting part 420 is no longer restricted, providing conditions for disassembling the suction cup 20.

[0037] As a preferred embodiment, refer to Figure 5 and Figure 7 The protrusion 5111 is at least partially arc-shaped, and the slot 2311 is at least partially annular. When the protrusion 5111 is inserted into the slot 2311, the connecting part 230 and the lifting part 420 can rotate relative to each other, so that the base 10 can rotate relative to the suction cup 20.

[0038] When the protrusion 5111 is engaged with the slot 2311, the arc-shaped protrusion 5111 and the annular slot 2311 cooperate with each other to provide a smooth movement trajectory for the relative rotation of the connecting part 230 and the lifting part 420, ensuring the flexibility of the rotation operation. This relative rotation allows the base 10 to rotate relative to the suction cup 20. In actual use of the vehicle suction cup 20 bracket, the user may need to adjust the angle of the smart terminal device on the base 10 according to different usage needs (such as adjusting the angle of the smart terminal to obtain a better viewing field), which meets the user's need for flexible adjustment of the smart terminal and improves the practicality of the product and the user experience.

[0039] Reference Figure 5 and Figure 7 In this embodiment, the first latching part 231 adopts a latching groove 2311, and the second latching part 511 adopts a latching protrusion 5111. The first latching part 231 has a ring structure.

[0040] As a preferred embodiment, refer to Figure 5 , Figure 7 and Figure 9 A rotation limiting structure is provided between the suction cup 20 and the base 10 to provide damping or positioning when the suction cup 20 rotates relative to the base 10. The rotation limiting structure includes a first limiting part 610 provided on the connecting part 230 or the protrusion 220, and a second limiting part 620 provided on the lifting part 420. Alternatively, the rotation limiting structure includes a first limiting part 610 provided on the skirt 210 and a second limiting part 620 provided on the base 10. Multiple first limiting parts 610 and second limiting parts 620 are provided and arranged in a circular array to form a ring-shaped arrangement. The other is an abutting structure that cooperates with the ring-shaped arrangement. The first limiting parts 610 and second limiting parts 620 can form an abutting engagement at multiple angular positions to achieve damped or positioned rotational adjustment of the suction cup 20 relative to the base 10. One of the first limiting parts 610 and second limiting parts 620 includes a protrusion 621, and the other includes a groove 611 that cooperates with the protrusion 621.

[0041] The rotation restriction structure allows the user to adjust the angle of the base 10 according to their actual needs, so that the position of the base 10 is fixed after it rotates relative to the suction cup 20. The smart terminal on the base 10 will not rotate on its own due to external forces (such as vibrations from driving), thus meeting the user's need for precise angle adjustment.

[0042] Reference Figure 7 and Figure 9In this embodiment, a first limiting part 610 is provided on the connecting part 230, a second limiting part 620 is provided on the lifting part 420, and the first limiting part 610 is a groove 611 and the second limiting part 620 is a protrusion 621.

[0043] As a preferred embodiment, refer to Figures 3 to 5 The control structure 520 also includes a sliding part 523, and the pressing part 521 and the driving part 522 are both connected to the sliding part 523. The base 10 is provided with a sliding joint for the sliding part 523 to slide. The side of the base 10 is also provided with an opening 101. The pressing part 521 protrudes from the opening 101 for external force to drive it. The driving part 522 is driven to connect with the second locking part 511. The driving part 522 includes a first pushing part 5221. The second locking part 511 is movably disposed in the lifting part 420. The second locking part 511 includes a second pushing part 5112 that cooperates with the first pushing part 5221. The first pushing part 5221 and the second pushing part 5112 movably abut against each other to make the locking protrusion 5111 move in the direction of disengaging from the locking groove 2311.

[0044] The control structure 520 also includes a sliding part 523, with the pressing part 521 and the driving part 522 connected to the sliding part 523 to form a whole. A sliding joint is provided inside the base 10 for the sliding part 523 to slide along a specific direction on the base 10 under the guidance of the sliding joint. Simultaneously, an opening 101 is provided on the side of the base 10, through which the pressing part 521 protrudes, allowing the user to apply external force to drive the sliding part 523 to slide, thereby causing the driving part 522 to move as well. When the sliding part 523 slides under the drive of the pressing part 521, the first pushing part 5221 of the driving part 522 pushes the second pushing part 5112 of the second locking part 511, causing the second locking part 511 to move, thereby causing the locking protrusion 5111 to move along the direction of disengaging from the locking groove 2311, thus unlocking the first locking part 231 and the second locking part 511.

[0045] Reference Figure 8 and Figure 9 The second locking part 511 is movably disposed on the lifting part 420, providing objective conditions for the movement of the second locking part 511 so as to unlock the first locking part 231 and the second locking part 511. In this embodiment, the bottom of the lifting part 420 is provided with a sliding groove 4201, and the second locking part 511 is slidably disposed in the sliding groove 4201.

[0046] As a preferred embodiment, refer to Figure 5 and Figure 6The drive unit 522 also includes a third pusher 5222, and the second latching part 511 includes a fourth pusher 5113 that cooperates with the third pusher 5222. The third pusher 5222 and the fourth pusher 5113 are in movable contact to cause the latching protrusion 5111 to move in the direction of entering the latching groove 2311.

[0047] When it is necessary to restore the first locking part 231 and the second locking part 511 to the locked state, the sliding part 523 slides under the action of a certain external force, which drives the third pushing part 5222 of the driving part 5222 to push the fourth pushing part 5113 of the second locking part 511, causing the second locking part 511 to move in the opposite direction, thereby driving the locking protrusion 5111 to move along the direction of entering the slot 2311, thereby realizing the locking of the first locking part 231 and the second locking part 511.

[0048] Reference Figure 5 and Figure 6 The present invention provides an embodiment in which the first pushing part 5221 and the second pushing part 5112 are in movable contact, and the third pushing part 5222 and the fourth pushing part 5113 are in movable contact. The first pushing part 5221 and the third pushing part 5222 are receiving grooves, and the second pushing part 5112 and the fourth pushing part 5113 are inserts. The inserts are inserted into the receiving grooves and abut against the receiving grooves.

[0049] As a preferred embodiment, refer to Figure 5 and Figure 6 The base 10 is also provided with a first elastic reset member 120. One end of the elastic reset member is connected to the base 10, and the other end is connected to the pressing part 521, or the other end is connected to the second snap-fit ​​part 511. The first elastic reset member 120 is used to drive the snap-fit ​​protrusion 5111 to move along the direction of entering the snap-fit ​​groove 2311.

[0050] The base 10 includes a first elastic reset member 120, one end of which is connected to the base 10, and the other end is connected to either the pressing part 521 or the second locking part 511. The main function of the first elastic reset member 120 is to provide an elastic force to drive the locking protrusion 5111 to move along the direction of entering the locking slot 2311, thereby restoring the first locking part 231 and the second locking part 511 to their locked state. For example, when the user presses the pressing part 521 to disengage the locking protrusion 5111 from the locking slot 2311 (unlocking), and then releases the pressing part 521, the first elastic reset member 120, under the action of the elastic force, pushes the pressing part 521 to move the second locking part 511, or directly moves the second locking part 511, causing the locking protrusion 5111 to re-enter the locking slot 2311, thus achieving automatic locking.

[0051] Reference Figure 6 In this embodiment, an example is given of the connection between the first elastic reset member 120 and the pressing part 521.

[0052] In this embodiment, the number of locking mechanisms 50 can be one or two; no specific limitation is made here. (Refer to...) Figure 5 Two examples of locking mechanism 50 are given, with the two locking mechanisms 50 distributed on opposite sides of the connecting part 230 along the length direction of the base 10.

[0053] As a preferred embodiment, refer to Figure 8 A second elastic reset member 130 is provided between the lifting part 420 and the base 10. The lifting part 420 is also provided with a movable block 421. The second limiting part 620 is a protrusion 621 on the movable block 421 facing the suction cup 20. The side of the lifting part 420 opposite to the protrusion 621 abuts against the second elastic reset member 130. One end of the second elastic reset member 130 can act on the movable block 421 so that the protrusion 621 abuts against the annular alignment structure, and the other end is connected to the base 10.

[0054] In this embodiment, the second elastic reset member 130 has two functions. First, after the control unit 410 controls the lifting unit 420 to move in the thickness direction of the base 10 to achieve vacuum connection between the suction cup 20 and the surface to be suctioned, the vacuum connection needs to be released, and reset can be achieved with the assistance of the second elastic reset member 130. Second, after the suction cup 20 is vacuum connected to the surface to be suctioned, the continuous abutting force of the second elastic reset member 130 on the movable block 421 ensures that the protrusion 621 on the movable block 421 is always tightly abutting against the annular array structure, thereby ensuring that the damping and positioning functions of the rotation restriction structure remain effective, preventing the base 10 from shifting at an angle during use, and improving the stability of the user's smart terminal.

[0055] In this embodiment, the number of protrusions 621 is not specifically limited. Figure 9 The example given is that protrusion 621 has two settings.

[0056] As a preferred embodiment, the control unit 410 is a lever, which is oscillatingly connected to the base 10 in the thickness direction. One end of the lever is directly or indirectly driven to the lifting unit 420 to drive the lifting unit 420 to reciprocate along the thickness direction of the base 10, and the other end is exposed outside the base 10 for operation by external force.

[0057] The control unit 410 is a rotating component, which is rotatably connected to the base 10 and can rotate relative to the base 10 along the axial direction of the suction cup 20. The rotating component is directly or indirectly driven connected to the lifting unit 420 to drive the lifting unit 420 to reciprocate along the thickness direction of the base 10. The rotating unit is at least partially exposed outside the base 10 for external force to drive it.

[0058] In this embodiment, two control unit 410 design schemes are presented. The lever structure is simple and labor-saving to operate; the rotating structure allows for more precise lifting and lowering adjustments. Providing two schemes increases product diversity and gives users more choices.

[0059] Reference Figure 8 In this embodiment, a specific implementation of the control unit 410 is given. Connecting plates 4101 are provided on both sides of the control unit 410 near the lifting part 420. A first shaft hole 4102 is formed on the connecting plate 4101. The connecting plate 4101 has a first end face 4103 and a second end face 4104. The distance between the second end face 4104 and the first shaft hole 4102 is greater than the distance between the first end face 4103 and the first shaft hole 4102. A second shaft hole (not shown in the figure) is formed on the side of the lifting part 420 near the control unit 410. The lifting part 420 is located between the two connecting plates 4101, and a rotating shaft 4105 is provided on the first shaft hole 4102 and the second shaft hole, so that the control unit 410 is rotatably mounted on the lifting part 420. When the control unit 410 is rotated so that the first end face 4103 abuts against the top of the base 10 (…),… Figure 1 and Figure 3 As shown), the suction cup 20 is lowered and squeezed to form a vacuum connection between the adsorbed surfaces. When the control unit 410 is rotated so that the second end face 4104 abuts against the top of the base 10 ( Figure 2 and Figure 4 As shown in the figure, the suction cup 20 is lifted and separated from the surface being suctioned, thus releasing the vacuum connection.

[0060] This application also discloses a support device, including the suction cup structure 100 in the foregoing embodiments. This support device has the same structure and beneficial effects as the suction cup structure 100 in the foregoing embodiments. The structure and beneficial effects of the suction cup structure 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0061] Reference Figure 10 The suction cup structure 100 has a mounting part 200 hinged to its base 10. The mounting part 200 is used to mount a smart terminal, such as a mobile phone. It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
