Description

Technical Field

[0001] This utility model relates to the field of buoys, and more particularly to a device for preventing objects from being sucked in and removed. Background Technology

[0002] With the rapid popularization of electronic products, smartphones, tablets, and e-readers have become increasingly important parts of daily life due to their diverse functions. However, this also leads to user dependence, with users spending long periods immersed in device operation, affecting learning efficiency, work performance, and physical and mental health. Although users are conscious of controlling their usage time, relying solely on personal self-control is often insufficient for sustained and effective management. Current mainstream solutions rely on software-based focus apps, which programmatically disable device functions or lock the screen during specific periods to limit usage. However, software locking mechanisms have significant limitations: their protection only applies to the operating system level. Users can easily bypass the restrictions through conventional or unconventional means such as entering a backup password, forcibly restarting the device, switching to safe mode, or exploiting system vulnerabilities. Teenage users, in particular, often quickly circumvent these restrictions due to their technological knowledge, significantly diminishing the effectiveness of software solutions. Therefore, there is an urgent need for a physical locking device that can directly act on the electronic device itself, mechanically securing it to prevent unauthorized removal or operation, thus providing a more stable and harder-to-avoid usage control method.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In the control of electronic product use, existing technologies rely on software-implemented locking mechanisms to limit usage time. However, because these mechanisms allow unlocking and necessary operations, users can bypass the restrictions by testing passwords or using unconventional methods, making it impossible to prevent the electronic product from being removed and thus hindering the achievement of the goal of controlling usage time. The core problem lies in the lack of physical isolation in the locking mechanism, making the locked state easily bypassed and consequently affecting the reliability of the control mechanism.

[0025] For example, in a home-based guardianship scenario, a guardian might activate attention-control software to limit a teenager's smartphone usage time. Even after the software locks the device, the electronic product may retain emergency call functionality or a system recovery option. The teenager could then repeatedly enter the password or utilize the recovery mode to successfully unlock the phone and continue using it, rendering the control intent ineffective. Furthermore, this breach allows the electronic product to be removed by the user even while locked, directly causing the usage time control process to fail as intended.

[0026] If the above problems are not solved, the mechanism for controlling usage time will not operate stably, users' dependence on electronic products will persist, and the effectiveness of time management will be affected. Therefore, there is an urgent need for a device that can physically lock electronic products.

[0027] This application discloses an object suction and anti-removal device, including a housing 100; the housing 100 is provided with an insertion groove 110 for allowing an object 500 to be clamped to be inserted and removed; the housing 100 is also provided with a receiving groove 120 communicating with the insertion groove 110; a support assembly 200 is provided in the receiving groove 120; a suction cup 300 is movably connected to the support assembly 200; the suction cup 300 is configured to enter and exit the insertion groove 110; a motor 250 is provided on the support assembly 200 to drive the suction cup 300 to move so that the suction cup 300 moves closer to or further away from the insertion groove 110, thereby controlling the distance between the suction cup 300 and the object 500 to be clamped; an air pump 400 connected to the suction cup 300 is provided in the receiving groove 120.

[0028] The housing 100 provides structural support as an overall frame; the insertion slot 110 allows the object to be clamped 500 to be inserted and removed; the receiving slot 120 is connected to the insertion slot 110, providing installation space for internal components. In practical applications, the support component 200 refers to the structure used to fix and guide the movement of the suction cup 300, mainly to ensure that the suction cup 300 can move along a predetermined path. The suction cup 300 is configured to enter and exit the insertion slot 110. In practical applications, the suction cup 300 refers to an elastic component that uses negative pressure to adsorb objects. It can be made of rubber or silicone material, such as a round suction cup or a duckbill-shaped suction cup, mainly to establish an airtight connection with the surface of the object to be clamped 500. The support assembly 200 is equipped with a motor 250 that drives the suction cup 300. In practical applications, the motor 250 refers to the power device that drives the suction cup 300 to reciprocate. It can be implemented using a stepper motor or a DC servo motor, such as a servo motor with an encoder. Its main purpose is to adjust the distance between the suction cup 300 and the object to be clamped 500. The receiving groove 120 is equipped with an air pump 400 connected to the suction cup 300. In practical applications, the air pump 400 refers to a suction device that generates negative pressure to maintain the suction force. It can be implemented using a miniature vacuum pump. Its main purpose is to reduce the air pressure inside the suction cup 300. The object to be clamped 500 is a common flat item such as a smartphone, tablet computer, or e-reader.

[0029] The device operates by using a housing 100 as a structural frame. Inside, there is an insertion slot 110 for inserting and removing an object 500, and a receiving slot 120 connected to the insertion slot 110. A support assembly 200 is installed within the receiving slot 120, and a suction cup 300 is movably connected to the support assembly 200, allowing the suction cup 300 to move in and out of the insertion slot 110. The suction cup 300 is driven by a motor 250 to control the distance between it and the object 500. An air pump 400 connected to the suction cup 300 is also located within the receiving slot 120. When the object 500 is placed in the insertion slot 110, the suction cup 300, driven by the motor 250, approaches the surface of the object 500. Upon contact, the air pump 400 activates, reducing the air pressure within the suction cup 300 and generating suction force, thus firmly securing the object 500 within the insertion slot 110 and preventing unauthorized removal. The movement trajectory of the suction cup 300 is provided by the support component 200 to provide a stable platform, ensuring the reliability of the adsorption process and avoiding adsorption failure due to shaking; the air pump 400 forms negative pressure by pumping air, so that the suction cup 300 and the surface of the object to be clamped 500 are closely attached, achieving direct fixation at the physical level.

[0030] Specifically, the suction cup 300 can be a vacuum suction cup made of silicone, which has good elasticity and sealing performance, can adapt to minor unevenness on different surfaces, and enhances the reliability of adsorption. As a preferred implementation, the motor 250 is a micro stepper motor 250, which has high motion precision and rapid response, and can accurately control the distance between the suction cup 300 and the object to be clamped 500, avoiding equipment damage caused by hard contact. Furthermore, the pumping capacity of the air pump 400 is dynamically adjusted according to the adsorption requirements, ensuring that an effective negative pressure is quickly formed after the suction cup 300 contacts the object to be clamped 500.

[0031] In one embodiment of this utility model, the support assembly 200 includes a first support plate 210 and a second support plate 220 fixedly disposed at a distance within a receiving groove 120; a motor 250 is fixedly connected to the first support plate 210; a movable plate 230 is movably disposed between the first support plate 210 and the second support plate 220; a nut seat 260 is fixedly connected to the movable plate 230; an output screw 251 is anti-rotatingly connected to the output shaft of the motor 250; the output screw 251 is located between the first support plate 210 and the second support plate 220. The first support plate 210 and the second support plate 220 are connected by a guide rod 240; the movable plate 230 is slidably connected to the guide rod 240; the suction cup 300 is fixedly connected to the movable plate 230; the second support plate 220 is provided with a clearance groove 221 that allows the suction cup 300 to move to the side of the second support plate 220 away from the first support plate 210; the motor 250 rotates and drives the nut seat 260 to reciprocate along the output screw 251, thereby driving the suction cup 300 to reciprocate up and down.

[0032] Among them, the anti-rotation connection refers to a mechanical fixing method that prevents relative rotation between two components. It can be achieved by keyway fit, spline connection, or pin limiter. The purpose is to ensure that the rotational power of the output shaft of motor 250 is efficiently transmitted to the output screw 251, avoiding loosening or slippage during movement. The guide rod 240 can be understood as a rigid guide element that limits the movement trajectory. It can be achieved by using a single high-rigidity guide rod with a precision bearing or multiple parallel guide rods. The purpose is to constrain the movable plate 230 to move only in the vertical direction, eliminating lateral degrees of freedom and reducing movement resistance. Nut seat 260 The cooperation with the output screw 251 refers to the transmission mechanism that converts rotary motion into linear motion based on the principle of threaded pairs. It can be implemented using trapezoidal threads, ball screws, or ordinary thread structures. The purpose is to achieve precise control of the displacement of the suction cup 300, so that the movement distance strictly corresponds to the speed of the motor 250. The clearance groove 221 is a structural opening that provides movement space for the suction cup 300. It can be designed as a circle, rectangle, or irregular contour. The purpose is to avoid structural interference between the suction cup 300 and the second support plate 220 when the suction cup 300 moves downward, and to ensure that the suction cup 300 can fully contact the surface of the object to be clamped 500.

[0033] In one embodiment of this utility model, at least two guide rods 240 are provided.

[0034] Specifically, the requirement of having at least two guide rods 240 means that the number of guide rods 240 is no less than two. These can be implemented using two, three, or more parallel rod-like structures. The purpose is to form geometric stability constraints through multi-point support, effectively limiting the lateral degree of freedom of the movable plate 230 and preventing rotation or displacement caused by lateral forces or vibrations during movement. The number of guide rods can be selected in different forms based on structural compactness and stiffness requirements. For example, a symmetrically distributed double-rod structure or a triangular multi-rod structure can be used. Its core function is to provide basic motion constraints, laying the structural foundation for the precise linear movement of the movable plate 230.

[0035] In one embodiment of this utility model, the suction cup 300 is fixedly connected to the movable plate 230 by a locking nut 310. For example... Figure 1 As shown, in one embodiment, the locking nut 310 can cooperate with one end face of the suction cup 300 to clamp the movable plate 230, thereby achieving a fixed connection between the suction cup 300 and the movable part.

[0036] Specifically, the solution of this application uses a locking nut 310 to rigidly fix the suction cup 300 to the movable plate 230. When the motor 250 drives the movable plate 230 to reciprocate along the guide rod 240, the thread preload generated by the locking nut 310 effectively resists vibration and air pressure fluctuations. When the suction cup 300 contacts the object to be clamped 500 and is compressed, this fixing method maintains the precise relative position between the suction cup 300 and the movable plate 230, avoiding slight displacement caused by changes in internal air pressure. This ensures a tight fit between the suction cup 300 and the surface of the object to be clamped 500, keeps the air circuit system airtight, and ensures that the negative pressure suction force generated by the air pump 400 continues to be effective.

[0037] In one embodiment of this utility model, the air pump 400 is connected to one port of the normally closed double-way solenoid valve 420 through the first pipe 410; the other port of the normally closed double-way solenoid valve 420 is connected to one port of the three-way solenoid valve 440 through the second pipe 430; one of the other two ports of the three-way solenoid valve 440 is connected to the atmosphere, and the other port is connected to one port of the three-way interface 460 through the third pipe 450; one of the other two ports of the three-way interface 460 is connected to the suction cup 300 through the fourth pipe 470, and the other port is airtightly connected to the air pressure sensor 141 through the fifth pipe 480.

[0038] Specifically, the normally closed two-way solenoid valve 420 refers to an electromagnetic control valve that automatically remains closed in the power-off state. It can be implemented using various normally closed solenoid valve structures, with the aim of ensuring that the system maintains air circuit sealing in the non-working state and effectively preventing air pressure leakage. The three-way solenoid valve 440 can be understood as an electromagnetic switching device with three fluid channels. It can be implemented using three-way solenoid valves 440 with different port configurations, with the aim of providing rapid air circuit switching capability, allowing the suction cup 300 to be immediately connected to the atmosphere during the release phase. The three-way interface 460 refers to the connection node used for fluid distribution, which can be implemented using Y-type or T-type diverter connectors, with the aim of allowing the suction cup 300 and the air pressure sensor 141 to share the same air circuit, facilitating synchronous monitoring of air pressure changes. The air pressure sensor 141 refers to a sensing element used to detect gas pressure, with the aim of acquiring real-time air pressure data inside the suction cup 300 to provide accurate feedback for automatic control.

[0039] Specifically, the solution in this application constructs a closed-loop air circuit control system through the synergistic action of an air pump 400, a solenoid valve, and a sensor. When the air pump 400 is running, gas is transmitted through the first pipe 410 to the normally closed double-way solenoid valve 420. When the solenoid valve is energized, it conducts airflow, allowing the gas to enter the three-way solenoid valve 440 through the second pipe 430. The three-way solenoid valve 440 selects the air path according to the control signal. When in a specific state, the gas flows through the third pipe 450 to the three-way interface 460. The three-way interface 460 distributes the airflow to the suction cup 300 connected to the fourth pipe 470 and the air pressure sensor 141 connected to the fifth pipe 480, realizing synchronous air pressure monitoring. The air pressure sensor 141 provides real-time feedback on the air pressure changes inside the suction cup 300 to the control circuit. The circuit dynamically adjusts the on / off state of the normally closed double-way solenoid valve 420 and the operation of the air pump 400 according to a preset threshold, thereby precisely controlling the suction force and maintaining stable locking. During the release phase, the three-way solenoid valve 440 switches to the state of being connected to the atmosphere, so that the negative pressure inside the suction cup 300 is quickly balanced, making it easy to remove the object 500.

[0040] In one embodiment of this utility model, the air pressure sensor 141 is disposed on the circuit board 140 located in the receiving groove 120; the normally closed double-way solenoid valve 420 and the three-way solenoid valve 440 are both electrically connected to the circuit board 140.

[0041] In practical applications, the pressure sensor 141 refers to a sensing device used to detect changes in gas pressure. It is mounted on the surface of the circuit board 140 to shorten the signal transmission path, with the aim of avoiding external interference from affecting the accurate acquisition of pressure data. The normally closed two-way solenoid valve 420 and the three-way solenoid valve 440 can be understood as actuators that control the switching of airflow channels. They can establish an electrical connection with the circuit board 140 through surface mount soldering, plug-in terminals, or flexible circuit connections, with the aim of simplifying the electrical path and improving the response speed of control commands.

[0042] In one embodiment of the present invention, the three-way solenoid valve 440 includes a first port 441, a second port 442, and a third port 443; the first port 441 is connected to a normally closed two-way solenoid valve 420 through a second pipe 430; the second port 442 is connected to a three-way interface 460 through a third pipe 450; and the third port 443 is connected to the atmosphere.

[0043] In one embodiment of the present invention, when the three-way solenoid valve 440 is in a de-energized state, the first port 441 is open, the second port 442 is open, and the third port 443 is closed; when the three-way solenoid valve 440 is in a energized state, the first port 441 is open or closed, the second port 442 is open, and the third port 443 is open.

[0044] Specifically, during the suction phase, the three-way solenoid valve 440 is de-energized, with the first port 441 and the second port 442 open while the third port 443 is closed, ensuring unobstructed airflow between the air pump 400 and the suction cup 300, while isolating the atmosphere, thereby creating a stable negative pressure adsorption environment inside the suction cup 300. During the release phase, the three-way solenoid valve 440 is energized, with the third port 443 opening to connect to the atmosphere, while the second port 442 remains open to maintain the airflow connection.

[0045] In one embodiment of the present invention, the receiving groove 120 is provided with a battery 130 that supplies power to the air pump 400, circuit board 140, normally closed double-way solenoid valve 420, and three-way solenoid valve 440.

[0046] In practical applications, battery 130 refers to a rechargeable and rechargeable electrochemical energy storage unit, which can be implemented using lithium-ion batteries, nickel-metal hydride batteries or lithium iron phosphate batteries. Its purpose is to provide independent and continuous power support for key electrical components and avoid affecting the device's locking function due to external power interruption.

[0047] When the object to be clamped 500 is placed into the insertion slot 110, the device is started, and the motor 250 begins to rotate. The output screw 251 of the motor 250 drives the nut seat 260 to move downward. The nut seat 260 then drives the movable plate 230 and the suction cup 300 fixedly connected to the movable plate 230 to move downward. The suction cup 300 first contacts the object to be clamped 500. As the distance between the suction cup 300 and the object to be clamped 500 gets closer and closer, the gas inside the suction cup 300 is compressed, and the air pressure gradually increases. Because the fourth pipe 470 passes through three... The port 460 is connected to the fifth pipe 480. After the pressure sensor 141, which is airtightly connected to the end of the fifth pipe 480, senses an increase in pressure, it controls the motor 250 to stop rotating via the circuit board 140. Simultaneously, the normally closed double-way solenoid valve 420 is powered on. After being powered on, the normally closed double-way solenoid valve 420 changes from a closed state to a conducting state. The three-way solenoid valve 440 remains de-energized (in the de-energized state, the first port 441 is open, the second port 442 is open, and the third port 440 is closed). With port 443 closed, the air passage between the air pump 400 and the two solenoid valves is unobstructed and connected to the suction cup 300. The air pump 400 then begins to pump air. As the air pump 400 continues to pump air, the air pressure between the suction cup 300 and the object to be clamped 500 decreases until the pressure inside the suction cup 300 reaches a threshold. At this point, the air pressure sensor 141 detects that the threshold has been reached, and the circuit board 140 controls the air pump 400 to stop working. The normally closed double-way solenoid valve 420 is also de-energized and remains in a closed, isolated state. In this state, the air pressure inside the suction cup 300 can be maintained, thus maintaining a stable suction force, and the object to be clamped 500 cannot be removed. When it is necessary to remove the object to be clamped 500 after a certain period of time, the circuit board 140 controls the three-way solenoid valve 440 to turn on the power (the third port 443 is open, the first port 441 is open or closed, and the second port 442 is open). The third port 443 of the three-way solenoid valve 440, which is connected to the atmosphere, is connected, the negative pressure inside the suction cup 300 is released, the suction force of the suction cup 300 disappears, and the object to be clamped 500 can be removed.

[0048] Specifically, the solution in this application achieves dynamic adjustment of the suction cup 300's adsorption process and precise triggering of the release operation through a closed-loop feedback mechanism between the pressure sensor 141 and the circuit board 140. When the object to be clamped 500 is placed in the insertion slot 110, the device is started, triggering the entire control sequence to avoid uncertainties caused by manual operation. When the motor 250 rotates and drives the suction cup 300 downwards, the design that the suction cup 300 contacts the object to be clamped 500 first ensures accurate device positioning and prevents adsorption failure due to misalignment. As the distance between the suction cup 300 and the object to be clamped decreases, the internal gas is compressed, causing the air pressure to increase. The pressure sensor 141 monitors this pressure change in real time and controls the motor 250 to stop rotating based on the signal of increased air pressure. This precisely terminates the movement after the suction cup 300 contacts the device a certain distance, preventing the suction cup 300 from continuing to descend and causing damage to the object to be clamped. Damage of 500; simultaneously, the normally closed double-way solenoid valve 420 is powered on to conduct, and combined with the power-off state of the three-way solenoid valve 440, a smooth air path is constructed, allowing the air pump 400 to start pumping air immediately and quickly establish a negative pressure environment; during the air pump 400's pumping process, the air pressure sensor 141 continuously monitors the pressure inside the suction cup 300, and controls the air pump 400 to stop working based on the signal that the pressure is low enough to reach the threshold, ensuring that the suction force is within the optimal range; after the normally closed double-way solenoid valve 420 is powered off, it closes the air path and maintains stable internal air pressure; when it is necessary to remove, the circuit board 140 controls the three-way solenoid valve 440 to be powered on, switching the air path to introduce atmospheric air into the suction cup 300 and release the negative pressure.

[0049] The normally closed two-way solenoid valve 420 can effectively save energy by only briefly operating when the air pump 400 is drawing in air, and remaining unenergized during the negative pressure phase. Similarly, the three-way solenoid valve 440 only briefly operates during venting and remains unenergized during drawing in air. Thus, after the negative pressure drawing in air is completed, neither the normally closed two-way solenoid valve 420 nor the three-way solenoid valve 440 is energized, effectively saving power consumption of the battery 130.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
