Description

Technical Field

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

[0002] To facilitate mobile phone use while driving, many users opt for electronic device holders. These holders typically include a connector that attaches to the car's center console or air vents. Most electronic device holders use a suction cup design for easy and quick connection to flat surfaces like the center console.

[0003] However, suction cups are prone to getting dirty during actual use, being repeatedly disassembled by users, or aging due to temperature effects, which can lead to a decrease in suction power. Since the suction cups are fixed to the electronic device bracket and cannot be removed, this can cause the entire electronic device bracket to become unusable. Utility Model Content

[0004] This utility model provides a suction cup structure and an electronic device bracket, which allows the suction cup to be disassembled for easy replacement, thereby reducing the user's operating costs.

[0005] 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 the suction cup includes a skirt made of soft rubber, a protrusion integrally extended 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 being displaceable 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. The system comprises a first latching part disposed on the connecting part, and a second latching part and the control structure disposed on the lifting part, both of which can reciprocate along the thickness direction of the base with the lifting part. The control structure is used to switch the connection state of the first latching part and the second latching 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, thereby locking the relative position of the connecting part and the lifting part in the thickness direction of the base, 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, thereby unlocking the relative position of the connecting part and the lifting mechanism in the thickness direction of the base, so that the suction cup is detachable relative to the base.

[0006] Optionally, the control structure includes a pressing part and a driving part. The pressing part is located on the side of the lifting part away from the skirt. At least one side of the pressing part is exposed on the top of the base to form a pressing surface, which is driven by an external force. The driving part is located on the pressing part on the side opposite to the pressing surface and is used to lock or unlock the first locking part and the second locking part. 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 locked, the locking protrusion engages with the locking groove. When the first locking part and the second locking part are unlocked, the locking protrusion can disengage from the locking groove. When the lifting part is displaced in the thickness direction of the base, the driving part and the second locking part move with the lifting part. At the same time, when there is no external force driving the pressing part, the relative position of the second locking part with respect to the driving part in the thickness direction of the base remains unchanged.

[0007] Optionally, at least a portion of the first and second locking parts are arc-shaped. When the first locking part is engaged with the second locking part, the connecting part and the lifting part can rotate relative to each other, so that the suction cup can rotate relative to the base.

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 array structure. The other is an abutting structure that cooperates with the ring array structure. 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.

[0009] Optionally, the driving part includes a first guide part, and the second engaging part is movably disposed on the lifting part. The second engaging part includes a second guide part that cooperates with the first guide part. The first guide part and the second guide part movably abut against each other to cause the second engaging part to move in a direction away from the first engaging part.

[0010] Optionally, the driving part further includes a third guide part, and the second engaging part includes a fourth guide part that cooperates with the third guide part. The third guide part and the fourth guide part are movably abutted together to move the second engaging part in the direction of engaging the first engaging part.

[0011] Optionally, a first elastic element is provided between the lifting part and the pressing part, and a movable block is also provided on the lifting part. The second limiting part is a protrusion on the movable block facing the suction cup. The side of the movable block opposite to the protrusion abuts against the first elastic element. One end of the first elastic element acts on the movable block so that the protrusion abuts against the annular array structure, and the other end acts on the pressing part so that the driving part drives the second locking part, so that the second locking part moves in the direction of locking into the first locking part.

[0012] 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 driven to the lifting unit to drive the lifting unit to reciprocate along the thickness direction of the base, while 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 capable of rotating relative to the base along the axial direction of the suction cup. The rotating component is directly or indirectly driven 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.

[0013] Optionally, when the control unit is a lever, the control unit and the lifting unit are connected via a movable frame, the movable frame is slidably connected to the base, and a second elastic element is provided between the lifting unit and the base; when the control unit is pressed down, the movable frame is driven to slide along the width direction of the base, thereby driving the lifting unit to slide away from the suction cup; when the control unit is lifted, the movable frame is driven to slide in the opposite direction, and the lifting unit is driven by the second elastic element to slide in the opposite direction relative to the base; the control unit includes a rotating part rotatably connected to the base, and a linkage rod and a force-applying part connected to the rotating part; the movable frame includes two parallel driving arms and a connecting arm connecting the two driving arms, the connecting arm is provided with a linkage groove, the driving arm is provided with a first inclined surface, and the lifting unit is provided with a second inclined surface corresponding to the first inclined surface; wherein, the force-applying part extends to the outside of the base, the linkage rod is engaged with the linkage groove, and the first inclined surface abuts against the second inclined surface.

[0014] This utility model also discloses an electronic device bracket, including the suction cup structure described in any one of the above.

[0015] The beneficial effects of the suction cup structure and electronic device bracket provided in this utility model embodiment are as follows: the lifting mechanism can effectively control the vacuum connection and release between the suction cup and the surface being adsorbed. The control unit drives the lifting unit to reciprocate along the thickness direction of the base, causing the connecting part to move, thereby changing the volume and air pressure of the sealed space between the suction cup and the surface being adsorbed. When the lifting unit moves upward, it pulls the connecting part, causing the protrusion of the suction cup to deform upward along with the skirt, increasing the volume of the sealed space, reducing the internal air pressure, and creating a vacuum state, thus achieving a firm adsorption between the suction cup and the surface being adsorbed. When the lifting unit moves downward, it pushes the connecting part, causing the protrusion to deform along with the skirt, reducing the volume of the sealed space, restoring the internal air pressure, releasing the vacuum adsorption, and facilitating the removal of the suction cup from the surface being adsorbed. Furthermore, the locking mechanism, in cooperation with the suction cup, enables a detachable connection between the connecting part and the lifting mechanism, thereby achieving the detachability of the suction cup relative to the base. When the suction cup experiences problems such as decreased suction power, users do not need to replace the entire electronic device bracket. They can simply use the control structure to put the locking mechanism in the second state, remove the old suction cup, and replace it with a new one to continue using the device. This greatly reduces user costs and minimizes resource waste. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] like Figures 1 to 4As shown, this utility model embodiment provides a suction cup structure 100, including: a base 110 and a suction cup 120; the base 110 is provided with a locking mechanism 130 and a lifting mechanism 140; the suction cup 120 is disposed at the bottom of the base 110, and the suction cup 120 includes a skirt 122 made of soft rubber, a protrusion 124 integrally extended from soft rubber in the central area of ​​the skirt 122, and a connecting part 126 with one end embedded in the protrusion 124 and the other end extending into the base 110, the connecting part 126 being connected to the lifting mechanism 140 through the locking mechanism 130. 0. Detachable connection; the lifting mechanism 140 includes a control unit 142 and a lifting unit 144. The lifting unit 144 is movably connected to the base 110 and can be displaced along the thickness direction of the base 110. The control unit 142 can directly or indirectly drive the lifting unit 144 to reciprocate along the thickness direction of the base 110, thereby controlling the suction cup 120 to vacuum connect or disconnect from the suction surface through the connecting part 126; the locking mechanism 130 includes a connecting structure 132 and a control structure 134; the connecting structure 132 includes a first snap-fit ​​that can be interconnected. The first engaging portion 1322 is disposed on the connecting portion 126, and the second engaging portion 1324 and the control structure 134 are both disposed on the lifting portion 144, and both can reciprocate along the thickness direction of the base 110 with the lifting portion 144. The control structure 134 is used to switch the connection state of the first engaging portion 1322 and the second engaging portion 1324. The control structure 134 has a first state and a second state. When the control structure 134 is in the first state, the first engaging portion 1322... 2. When the first and second latching parts 1322 and 1324 are in the locked state, the relative positions of the connecting part 126 and the lifting part 144 in the thickness direction of the base 110 are locked, so that the suction cup 120 is not detachable from the base 110. When the control structure 134 is in the second state, the first latching part 1322 and the second latching part 1324 are in the unlocked state, so that the relative positions of the connecting part 126 and the lifting mechanism 140 in the thickness direction of the base 110 are unlocked, so that the suction cup 120 is detachable from the base 110.

[0033] Specifically, the base 110 serves as the mounting foundation and load-bearing component of the entire suction cup structure 100, providing a stable mounting space and motion guide for the locking mechanism 130 and the lifting mechanism 140. In practical applications, to facilitate the assembly of other components, the base 110 is typically designed as a separate structure, which can be aligned and fixed after the other components are assembled. The skirt 122 of the suction cup 120 is made of soft rubber, typically silicone or rubber with good elasticity, sealing properties, and aging resistance. The protrusion 124 is located in the central area of ​​the skirt 122 and is integrally formed by the soft rubber constituting the skirt 122. This one-piece molded structure design ensures the connection strength between the protrusion 124 and the skirt 122, preventing air leakage or structural damage due to weak connections. Simultaneously, the protrusion 124 provides a carrier for the installation of the connecting part 126 and strengthens the connection strength, ensuring reliability when connected to the connecting part 126. One end of the connecting part 126 is embedded in the protrusion 124, and the other end extends into the base 110, for connecting the suction cup 120 and the lifting mechanism 140 inside the base 110. The embedded connection between the connecting part 126 and the protrusion 124 must ensure sufficient firmness, usually by means of interference fit, bonding, or integral injection molding, to prevent the connecting part 126 and the protrusion 124 from separating during use. The end of the connecting part 126 extending into the base 110 is detachably connected to the lifting mechanism 140 through the locking mechanism 130, thereby realizing the replaceable design of the suction cup 120.

[0034] Furthermore, the lifting unit 144 is movably connected to the base 110 and can move along the thickness direction of the base 110. The movable connection between the lifting unit 144 and the base 110 typically employs a sliding fit. For example, a guide groove is provided on the base 110, and a guide block that mates with the guide groove is provided on the lifting unit 144, ensuring that the lifting unit 144 does not deviate during movement and guaranteeing the stability and accuracy of the movement. The lifting unit 144 is connected to the connecting part 126 via a locking mechanism 130. When the lifting unit 144 moves along the thickness direction of the base 110, it drives the connecting part 126 to move synchronously, thereby pulling or pushing the protrusion 124 and skirt 122 of the suction cup 120, changing the volume of the sealed space between the suction cup 120 and the surface being suctioned, thus achieving air pressure change. The control unit 142 can directly or indirectly drive the lifting unit 144 to reciprocate along the thickness direction of the base 110, converting the external force applied by the user into the power to drive the movement of the lifting unit 144, thereby controlling the movement of the lifting unit 144. When the user operates the control unit 142, the control unit 142 drives the lifting unit 144 to move up or down, thereby controlling the suction cup 120 to adhere to or detach.

[0035] The locking mechanism 130, through the cooperation of the connecting structure 132 and the control structure 134, enables the suction cup 120 to be detachable or non-detachable relative to the base 110. During cooperation, the first latching part 1322 on the connecting part 126 and the second latching part 1324 on the lifting part 144 engage or disengage under the action of the control structure 134. When the control structure 134 is in its first state, the first latching part 1322 and the second latching part 1324 are locked. At this time, the first latching part 1322 and the second latching part 1324 engage, restricting the relative position of the connecting part 126 and the lifting part 144 in the thickness direction of the base 110, preventing the connecting part 126 from moving or disengaging relative to the lifting part 144, thereby making the suction cup 120 non-detachable from the base 110. In this state, the entire suction cup structure 100 can stably perform the adsorption function, meeting normal usage requirements. When the control structure 134 is in the second state, the first latching part 1322 and the second latching part 1324 are unlocked. At this time, the first latching part 1322 and the second latching part 1324 can be separated, and the relative position restriction between the connecting part 126 and the lifting mechanism 140 in the thickness direction of the base 110 is released. The user can easily detach the connecting part 126 from the lifting part 144, thereby realizing the detachability of the suction cup 120 relative to the base 110.

[0036] The suction cup structure 100 provided in this application can effectively control the vacuum connection and release between the suction cup 120 and the surface being adsorbed via the lifting mechanism 140. The control unit 142 drives the lifting unit 144 to reciprocate along the thickness direction of the base 110, causing the connecting part 126 to move, thereby changing the volume and air pressure of the sealed space between the suction cup 120 and the surface being adsorbed. When the lifting unit 144 moves upward, it pulls the connecting part 126, causing the protrusion 124 of the suction cup 120 to deform upward along with the skirt 122, increasing the volume of the sealed space, reducing the internal air pressure, and creating a vacuum state, thus achieving a firm adsorption between the suction cup 120 and the surface being adsorbed. When the lifting unit 144 moves downward, it pushes the connecting part 126, causing the protrusion 124 to deform along with the skirt 122, reducing the volume of the sealed space, restoring the internal air pressure, releasing the vacuum adsorption, and facilitating the removal of the suction cup 120 from the surface being adsorbed. Based on this, the locking mechanism 130, in cooperation with the suction cup 120, enables a detachable connection between the connecting part 126 and the lifting mechanism 140, thereby allowing the suction cup 120 to be detached from the base 110. When the suction cup 120 experiences a decrease in suction power, the user does not need to replace the entire electronic device bracket. Instead, by controlling the locking mechanism 134 to the second state, the old suction cup 120 can be removed and replaced with a new one, allowing continued use. This significantly reduces user costs and minimizes resource waste.

[0037] like Figure 5 , Figure 6 and Figure 7 As shown, the control structure 134 includes a pressing part 1342 and a driving part 1344. The pressing part 1342 is disposed on the side of the lifting part 144 away from the skirt 122. At least one side of the pressing part 1342 is exposed on the top of the base 110 to form a pressing surface 1342a, which is driven by external force. The driving part 1344 is disposed on the side of the pressing part 1342 opposite to the pressing surface 1342a, and is used to lock or unlock the first locking part 1322 and the second locking part 1324. One of the first locking part 1322 and the second locking part 1324 is included... The first part 1322 and the second part 1324 are locked together, and the second part 1324 is locked together. When the first part 1322 and the second part 1324 are unlocked, the first part 1322 and the second part 1324 are unlocked. When the first part 1322 and the second part 1324 are unlocked, the first part 1322 can disengage from the second part 1324. When the lifting part 144 is displaced in the thickness direction of the base 110, the driving part 1344 and the second part 1324 move with the lifting part 144. At the same time, when there is no external force driving the pressing part 1342, the relative position of the second part 1324 relative to the driving part 1344 in the thickness direction of the base 110 remains unchanged.

[0038] Specifically, the pressing surface 1342a is designed to facilitate the application of external force by the user, improving user comfort and convenience during operation. The material of the pressing part 1342 can be the same as that of the base 110 or a more resilient material to ensure that it is not easily damaged during repeated pressing. When the user presses the pressing part 1342, the driving part 1344 generates a driving force to lock or unlock the first locking part 1322 and the second locking part 1324. In addition, one of the first locking part 1322 and the second locking part 1324 includes a locking protrusion, and the other includes a locking groove that engages with the locking protrusion. When the first locking part 1322 and the second locking part 1324 are in the locked state, the locking protrusion engages with the locking groove to ensure sufficient connection strength after engagement, preventing the locking protrusion from disengaging from the locking groove during normal use, and ensuring a reliable connection between the suction cup 120 and the base 110. When the first locking part 1322 and the second locking part 1324 are in the unlocked state, the locking protrusion can disengage from the locking groove. To achieve this state, the driving unit 1344 needs to apply external force to displace either the second locking part 1324 or the first locking part 1322, thereby releasing the engagement between the locking protrusion and the locking slot. For example, when the driving unit 1344 pushes the second locking part 1324 away from the first locking part 1322, the locking slot moves with the second locking part 1324, causing the locking protrusion to disengage from the locking slot and thus unlocking the device. The second locking part 1324 and the lifting unit 144 can be connected by a sliding connection or a rotating connection, as long as the engagement between the second locking part 1324 and the first locking part 1322 is maintained.

[0039] like Figure 6 and Figure 7 As shown, at least a portion of the first latching part 1322 and the second latching part 1324 are arc-shaped. When the first latching part 1322 is engaged with the second latching part 1324, the connecting part 126 and the lifting part 144 can rotate relative to each other, so that the suction cup 120 can rotate relative to the base 110.

[0040] Specifically, at least a portion of the first latching portion 1322 and the second latching portion 1324 are arc-shaped. In the locked state, the arc-shaped contact surfaces of the latching protrusion and the latching groove allow relative sliding between them, thereby achieving rotation. The range of rotation angles can be designed according to actual usage requirements, typically allowing 360° omnidirectional rotation along the central axis of the suction cup 120 or rotation within a specific angle range to meet different user needs regarding the placement angle of electronic devices. For example, when used on a car center console, users can adjust the orientation of electronic devices (such as mobile phones or navigation devices) by rotating the suction cup 120 according to their own viewing needs, improving ease of use.

[0041] like Figure 6 and Figure 8 As shown, a rotation limiting structure is provided between the suction cup 120 and the base 110 to provide damping or positioning when the suction cup 120 rotates relative to the base 110. The rotation limiting structure includes a first limiting part 127 provided on the connecting part 126 or the protrusion 124, and a second limiting part 1443 provided on the lifting part 144; or, the rotation limiting structure includes a first limiting part 127 provided on the skirt 122, and a second limiting part 1443 provided on the base 110; wherein, the first limiting part... One of the first limiting part 127 and the second limiting part 1443 is provided in multiples and is arranged in a circular array to form a ring array structure. The other is an abutting structure that cooperates with the ring array structure. The first limiting part 127 and the second limiting part 1443 can form an abutting engagement at multiple angular positions to realize the damped or positioned rotational adjustment of the suction cup 120 relative to the base 110. One of the first limiting part 127 and the second limiting part 1443 includes a protrusion, and the other includes a groove that cooperates with the protrusion.

[0042] Specifically, the rotation limiting structure solves the problem of excessively flexible rotation and inability to position that may result from relying solely on the arc-shaped snap-fit ​​structure, achieving damping or positioning functions when the suction cup 120 rotates relative to the base 110. Specifically, if the first limiting part 127 is located on the connecting part 126, it is typically distributed around the axis of the connecting part 126, forming an integral or fixed connection with it; if it is located on the protrusion 124, it is the same as the case with the connecting part 126, i.e., arranged around the axis of the protrusion 124, only with a slight deviation in actual position. The second limiting part 1443 is located on the side of the lifting part 144 facing the connecting part 126 or the protrusion 124, corresponding to the first limiting part 127, ensuring accurate engagement between the two during rotation. If the first limiting part 127 is provided on the skirt 122 and the second limiting part 1443 is provided on the base 110, the skirt 122 is the part that contacts the suction cup 120 with the surface to be attracted, and its edge area can be used to set the first limiting part 127, which is usually distributed along the circumferential direction of the skirt 122; the second limiting part 1443 is provided on the base 110 at the position corresponding to the skirt 122. The two cooperate when the suction cup 120 rotates to achieve a damping or positioning effect.

[0043] Furthermore, if the first limiting part 127 is a protrusion, and multiple protrusions are arranged in a circular array, these protrusions are evenly arranged around the rotation axis of the suction cup 120 to form a ring array; if the first limiting part 127 is a groove, multiple grooves arranged in a circular array can also form a ring array structure. The number of ring arrays, the size and spacing of the protrusions / grooves need to be determined according to the positioning accuracy requirements. The more protrusions, the more precise the positioning angle that can be achieved. Typically, 6, 8, 10, or 12 protrusions can be designed. In practical applications, the second limiting part 1443 can be set to one or two, and the first limiting part 127 can be set to more. When a protrusion is embedded in a groove, without external force, the protrusion will be restricted to its current position by the groove, preventing the suction cup 120 from rotating freely, thus achieving positioning. If the user needs to adjust the angle, sufficient external force needs to be applied to make the protrusion disengage from the current groove, move to the next groove and embed, thereby achieving positioning at different angles.

[0044] like Figure 5 and Figure 7 As shown, the drive unit 1344 includes a first guide part 1344a and a second engaging part 1324 movably disposed on the lifting unit 144. The second engaging part 1324 includes a second guide part 1324a that cooperates with the first guide part 1344a. The first guide part 1344a and the second guide part 1324a movably abut against each other to cause the second engaging part 1324 to move in the direction of disengaging from the first engaging part 1322.

[0045] Specifically, when the user presses the pressing part 1342, the pressing part 1342 drives the driving part 1344 to move downward along the thickness direction of the base 110, and the first guide part 1344a and the second guide part 1324a come into contact and interact. As the pressing part 1342 continues to press down, the first guide part 1344a will generate a lateral thrust on the second guide part 1324a, causing the second locking part 1324 to move away from the first locking part 1322 along the guide structure on the lifting part 144. This guide structure can be in the form of a sliding groove and a sliding rail, or it can be in the form of a rotating connection between the lifting part 144 and the second locking part 1324 connected by a rotating shaft. When the second locking part 1324 moves to the position where the locking protrusion is completely disengaged from the locking groove, the first locking part 1322 and the second locking part 1324 are unlocked, and the user can then remove the connecting part 126 of the suction cup 120 from the lifting part 144 to complete the unlocking process.

[0046] Please continue to refer to this. Figure 5 and Figure 7 The drive unit 1344 also includes a third guide unit 1344b, and the second engaging unit 1324 includes a fourth guide unit 1324b that cooperates with the third guide unit 1344b. The third guide unit 1344b and the fourth guide unit 1324b are in movable contact to move the second engaging unit 1324 in the direction of engaging the first engaging unit 1322.

[0047] Specifically, when the user releases the pressing part 1342, the pressing part 1342 can move upward along the thickness direction of the base 110 under the action of the restoring force, driving the third guide part 1344b of the drive part 1344 to move upward synchronously. The third guide part 1344b contacts and interacts with the fourth guide part 1324b. When the third guide part 1344b moves upward, it will generate a lateral thrust on the fourth guide part 1324b, causing the second locking part 1324 to move along the guide structure on the lifting part 144 towards the first locking part 1322. When the second locking part 1324 moves to the position where the locking protrusion is fully engaged in the slot, the first locking part 1322 and the second locking part 1324 return to the locked state, the connection between the suction cup 120 and the base 110 is fixed, and the locking process is completed.

[0048] like Figure 8As shown, a first elastic member 150 is provided between the lifting part 144 and the pressing part 1342. The lifting part 144 is also provided with a movable block 1442. The second limiting part 1443 is a protrusion on the movable block 1442 facing the suction cup 120. The side of the movable block 1442 opposite to the protrusion abuts against the first elastic member 150. One end of the first elastic member 150 acts on the movable block 1442 so that the protrusion abuts against the annular array structure, and the other end acts on the pressing part 1342 so that the driving part 1344 drives the second locking part 1324 so that the second locking part 1324 moves in the direction of locking into the first locking part 1322.

[0049] Specifically, the first elastic element 150 is typically a compression spring. One end of the first elastic element 150 abuts against the pressing part 1342, and the other end abuts against the lifting part 144 or the movable block 1442. When the pressing part 1342 is not subjected to external force, the first elastic element 150 is in a slightly compressed state, providing upward support force for the pressing part 1342. When the pressing part 1342 is pressed downward by external force, the first elastic element 150 is compressed and stores elastic potential energy. When the external force is removed, the first elastic element 150 releases the elastic potential energy, pushing the pressing part 1342 upward to reset and return to the initial position. Furthermore, the first elastic element 150 not only provides a restoring force for the pressing part 1342, but also provides a resisting force for the second limiting part 1443 on the movable block 1442, ensuring that the second limiting part 1443 (protrusion) is always tightly abutted against the annular array structure. Even under long-term use or vibration environments (such as during vehicle operation), the second limiting part 1443 will not detach from the annular array structure, ensuring the stability of the rotation limiting function. At the same time, the stable resisting force ensures that the protrusion is fully embedded in the groove during positioning, avoiding positioning loosening or displacement due to insufficient resisting force, improving positioning accuracy and reliability, and ensuring the stability of the electronic device angle.

[0050] In an optional embodiment of this application, the control unit 142 is a lever, which is oscillatingly connected to the base 110 in the thickness direction. One end of the lever is directly or indirectly driven to the lifting unit 144 to drive the lifting unit 144 to reciprocate along the thickness direction of the base 110, and the other end is exposed outside the base 110 for operation by external force. Alternatively, the control unit 142 is a rotating member, which is rotatably connected to the base 110 and can rotate relative to the base 110 along the axial direction of the suction cup 120. The rotating member is directly or indirectly driven to the lifting unit 144 to drive the lifting unit 144 to reciprocate along the thickness direction of the base 110, and the rotating unit 1422 is at least partially exposed outside the base 110 for operation by external force.

[0051] Specifically, when the lever drives the lifting part 144 to reciprocate along the thickness direction of the base 110 via swinging motion, the lever is oscillatingly connected to the base 110, with the oscillation direction being the thickness direction of the base 110 (i.e., up and down oscillation). This connection is typically achieved through a pivot or hinge. For example, a pivot hole is provided on the base 110, and a corresponding pivot is provided on the lever, allowing the lever to swing flexibly around the pivot. The oscillation angle needs to be determined based on the travel distance of the lifting part 144 to ensure that the lifting part 144 can complete the entire travel distance from adsorption to de-adsorption. One end of the lever is directly or indirectly driven connected to the lifting part 144, while the other end is exposed on the base 110 for external force operation. The driving end of the lever is directly in contact with or fixedly connected to the lifting part 144. When the lever oscillates, it directly pushes or pulls the lifting part 144 to move through the lever principle. For example, one end of the lever (drive end) is hinged to the lifting part 144, while the other end (operating end) is exposed. When the operating end is pressed, the drive end swings upward, pulling the lifting part 144 upward; when the operating end is lifted, the drive end swings downward, pushing the lifting part 144 downward. In addition, the lever can also be driven by other components to better adapt to the current structural form.

[0052] When the rotating component drives the lifting part 144 to reciprocate along the thickness direction of the base 110 via rotational motion, the rotating component is rotatably connected to the base 110 and can rotate relative to the base 110 along the axial direction of the suction cup 120, while ensuring that no axial offset (movement along the thickness direction of the base 110) occurs during rotation. An internal thread is provided on the inner side of the rotating component, and a corresponding external thread is provided on the outer side of the lifting part 144; the two are threadedly engaged. When the rotating component rotates, the relative movement of the threads drives the lifting part 144 to move along the thickness direction of the base 110.

[0053] like Figures 9 to 12As shown, when the control unit 142 is a lever, the control unit 142 and the lifting unit 144 are connected via a movable frame 146. The movable frame 146 is slidably connected to the base 110, and a second elastic element 148 is provided between the lifting unit 144 and the base 110. When the control unit 142 is pressed down, the movable frame 146 is driven to slide along the width direction of the base 110, thereby driving the lifting unit 144 to slide away from the suction cup 120. When the control unit 142 is lifted, the movable frame 146 is driven to slide in the opposite direction, and the lifting unit 144 is driven by the second elastic element 148 to slide in the opposite direction relative to the base 110. The control unit 142 includes a rotating part 14 that is rotatably connected to the base 110. 22, and a linkage rod 1424 and a force-applying part 1426 connected to the rotating part 1422; the movable frame 146 includes two parallel driving arms 1462 and a connecting arm 1464 connecting the two driving arms 1462. The connecting arm 1464 is provided with a linkage groove 1466, the driving arm 1462 is provided with a first inclined surface 1462a, and the lifting part 144 is provided with a second inclined surface 1444 corresponding to the first inclined surface 1462a; wherein, the force-applying part 1426 extends to the outside of the base 110, the linkage rod 1424 is engaged with the linkage groove 1466, and the first inclined surface 1462a abuts against the second inclined surface 1444.

[0054] Specifically, the lever includes a rotating part 1422 rotatably connected to the base 110, a linkage rod 1424 and a force-applying part 1426 connected to the rotating part 1422. The rotating part 1422 can cooperate with the pivot hole on the base 110 to ensure that the lever can swing flexibly around the rotating part 1422 in the thickness direction of the base 110. When the user presses down the force-applying part 1426 of the lever, the lever swings downward around the rotating part 1422, causing the linkage rod 1424 to swing synchronously. The linkage rod 1424 slides in the linkage groove 1466 of the connecting arm 1464 of the movable frame 146, pushing the movable frame 146 to slide along the width direction of the base 110 (e.g., to the left). The drive arm 1462 of the movable frame 146 moves with the movable frame 146. The first inclined surface 1462a on the drive arm 1462 interacts with the second inclined surface 1444 of the lifting part 144, converting the lateral force into a longitudinal force through the inclined surface cooperation, pushing the lifting part 144 to move upward along the thickness direction of the base 110. When the lifting part 144 moves upward, it pulls the connecting part 126 of the suction cup 120, creating a vacuum between the suction cup 120 and the surface to be attracted, thus achieving attraction; at the same time, the second elastic element 148 is compressed, storing elastic potential energy. When the user lifts the force-applying part 1426 of the lever, the lever swings upward around the rotating part 1422, causing the linkage rod 1424 to swing in the opposite direction, pulling the movable frame 146 to slide in the opposite direction along the width direction of the base 110 (e.g., to the right). The drive arm 1462 of the movable frame 146 moves in the opposite direction, the thrust of the first inclined surface 1462a on the second inclined surface 1444 disappears, the second elastic element 148 releases its elastic potential energy, and pushes the lifting part 144 downward along the thickness direction of the base 110 to return to the initial position. When the lifting part 144 moves downward, it pushes the connecting part 126 of the suction cup 120, thereby releasing the vacuum state between the suction cup 120 and the surface being suctioned, thus achieving suction release.
