Description

Technical Field

[0001] The utility model relates to the technical field of suction cup brackets, in particular to an electric suction cup bracket. Background Art

[0002] In today's daily life, adsorption structures are a common connection device that is widely used in various occasions where objects need to be fixed. This structure can firmly fix objects at the user's preset position through its adsorption effect, greatly facilitating people's life and work. However, although adsorption structures play an important role in fixing objects, they also have some significant limitations in practical applications.

[0003] The fixing effect of traditional adsorption structures, such as natural adsorption suction cups or magnetic adsorption devices, is often significantly affected by the external environment. In the case of natural adsorption, the adsorption force between the suction cup and the contact surface is easily affected by various factors such as humidity, cleanliness, surface roughness, etc., causing the object to loosen, shift or even fall off due to external forces. For magnetic adsorption devices, their adsorption effect is limited by the magnetic properties of the contact surface and the uniformity of the magnetic field distribution, and similar problems also exist.

[0004] In addition, when a user needs to remove an object fixed on the adsorption structure, he usually needs to overcome the adsorption force generated by the adsorption structure. For a naturally adsorbed suction cup, this often requires the user to exert a large amount of force, and may even require the use of tools to assist, which undoubtedly increases the difficulty and inconvenience of the user's operation. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of the present invention is to provide an electric suction cup bracket to solve the problems raised in the above background.

[0007] (II) Technical solution

[0008] An electric suction cup bracket comprises a top shell, a bottom shell is installed at the top end of the top shell, a suction cup is arranged on the bottom shell, and a sealing ring is installed on the outer surface of the suction cup, an abutting convex point is arranged at the bottom end of the bottom shell, an abutting convex point is arranged at the bottom end of the suction cup, and an air hole is arranged on the outer surface of the suction cup, a first switch and a motor are arranged inside the bottom shell, and a crank is connected to one end of the motor, a vacuum cylinder is connected to one end of the crank, and two one-way valves are arranged inside the vacuum cylinder, a three-way air pipe is connected to one side of the vacuum cylinder, and the other two ends of the three-way air pipe are respectively connected to an air pressure sensor and an air hole, and a first control board is connected to one side of the air pressure sensor;

[0009] It also includes a push rod and a second control panel arranged inside the bottom shell, a spring, an air pump and a cavity assembly arranged inside the bottom shell, a third switch and a second switch arranged on both sides of the push rod, a first air pump interface and a second air pump interface arranged at one end of the air pump, a third cavity interface, a second cavity interface and a first cavity interface arranged on one side of the cavity assembly, and the third cavity interface and the second cavity interface of the air pump are connected to each other through an air outlet pipe, the second cavity interface and the first air pump interface are connected to each other through an air extraction pipe, and the second cavity interface and the air hole are connected to each other through the air extraction pipe.

[0010] Preferably, the two one-way valves are made of soft material, and the incisions can be automatically closed.

[0011] Preferably, the bottom end of the suction cup is arc-shaped.

[0012] Preferably, the top shell and the bottom shell are connected by screws.

[0013] It can be seen from the above technical solutions that this application has the following beneficial effects:

[0014] 1. One of the core components of the utility model electric suction cup bracket is the air pressure switch, which is a device that can automatically operate according to the air pressure value in the closed cavity. The air pressure switch plays a key role when the suction cup is performing adsorption operation. When the suction cup is tightly fitted with the surface of the object to be adsorbed, the air in the closed cavity is extracted by the air pump to gradually reduce the air pressure in the cavity. The air pressure switch can monitor the air pressure value in the cavity in real time. When the air pressure reaches the preset adsorption value, the air pressure switch will send a signal to the control system, and the control system will then control the motor to stop working to maintain the stable adsorption state of the suction cup. Conversely, when the air pressure in the cavity increases due to some reasons (such as air leakage), the air pressure switch will send a signal again to start the air pump for air extraction to ensure that the suction cup can continuously and stably adsorb objects. This intelligent air pressure switch control not only improves the adsorption efficiency and stability of the suction cup, but also reduces the difficulty of operation and labor costs.

[0015] 2. The utility model is made of soft material through two one-way valves and has a unique opening and closing mechanism. During the process of motor vacuuming, the one-way valve of soft material allows gas to flow out of the cavity, but prevents external air from entering. This one-way flow characteristic ensures the efficiency and airtightness of the vacuuming process. When the motor stops working, the one-way valve will automatically close to prevent the gas in the cavity from flowing back or the outside air from infiltrating. This design not only improves the adsorption performance of the suction cup, but also enhances its sealing and durability. In addition, the one-way valve of soft material also has a certain elasticity and durability, and can adapt to pressure changes in different working environments, thereby ensuring the stability and reliability of the suction cup bracket under various conditions.

DETAILED DESCRIPTION

Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0023] See also Figure 1-5 , an embodiment provided by the utility model:

[0024] An electric suction cup bracket comprises a top shell 1, a bottom shell 2 is installed at the top of the top shell 1, a suction cup 611 is provided on the bottom shell 2, and a sealing ring 5 is installed on the outer surface of the suction cup 611, a contact convex point 3 is provided at the bottom end of the bottom shell 2, and an air hole 4 is provided on the outer surface of the suction cup 611, a first switch 6 and a motor 7 are provided inside the bottom shell 2, and a crank 8 is connected to one end of the motor 7, a piston rod 9 is connected to one end of the crank 8, a vacuum cylinder 911 is connected to one end of the piston rod 9, and two one-way valves are provided inside the vacuum cylinder 911, a three-way air pipe 511 is connected to one side of the vacuum cylinder 911, and the other two ends of the three-way air pipe 511 are respectively connected to an air pressure sensor 913 and the air hole 4, and a first control board 912 is connected to one side of the air pressure sensor 913;

[0025] It also includes a push rod 821 and a second control board 811 arranged inside the bottom shell 2, a spring 812, an air pump 819, and a cavity assembly 711 arranged inside the bottom shell 2, a third switch 822 and a second switch 820 are arranged on both sides of the push rod 821, an air pump first interface 816 and an air pump second interface 818 are opened at one end of the air pump 819, a cavity third interface 815 and a cavity second interface 814, and a cavity first interface 813 are opened on one side of the cavity assembly 711, and the cavity third interface 815 and the air pump second interface 818 are connected to each other through the air outlet pipe 817, the cavity second interface 814 and the air pump first interface 816 are connected to each other through the air extraction pipe 211, and the cavity second interface 814 and the air hole 4 are connected to each other through the air extraction pipe 211.

[0026] Furthermore, the two one-way valves are made of soft material, and the cutouts can be automatically closed, which enhances the sealing and stability of the system. This helps to maintain the negative pressure inside the suction cup and improve the adsorption effect. At the same time, the soft material also has a certain elasticity and durability, which can adapt to the pressure changes in different working environments and extend the service life.

[0027] Furthermore, the bottom end of the suction cup 611 is arc-shaped, and the arc-shaped bottom end design of the suction cup 611 can better fit the surface of the object, thereby increasing the adsorption area and adsorption force.

[0028] Furthermore, the top shell 1 and the bottom shell 2 are connected by screws, and the top shell 1 and the bottom shell 2 are connected by screws, so that the structure of the bracket is more solid and reliable. The screw connection not only provides a strong connection force, but also can prevent loosening or falling off due to vibration or impact during use. In addition, the screw connection is also convenient for disassembly and maintenance, which improves the maintainability of the bracket.

[0029] Working principle: When the motor 7 is the driving mechanism, the output shaft of the motor 7 is connected to the crank 8, and the rotation of the crank 8 is used to drive the piston in the vacuum cylinder 911 to move back and forth. When it is necessary to adsorb an object, the user brings the suction cup into contact with the surface of the object and starts the adsorption process by pressing the protrusion 3. At this time, the motor 7 starts to work, and drives the piston in the vacuum cylinder 911 to move back and forth through the crank 8, thereby extracting the air inside the suction cup 611 and forming a negative pressure inside the suction cup 611. At the same time, the sealing ring 5 enhances the sealing between the suction cup 611 and the surface of the object, ensuring the formation and maintenance of negative pressure. During the adsorption process, the air pressure sensor 913 monitors the air pressure inside the suction cup in real time. When the air pressure reaches the set upper limit value, the first control board 912 will receive the signal from the air pressure sensor and control the motor 7 to stop working. At this time, a certain negative pressure state is maintained inside the suction cup 611, thereby achieving stable adsorption of the object;

[0030] When the air pump is the driving mechanism, the electric suction cup bracket is in the non-working state, the push rod 821 is in the initial position, the spring 812 is in the uncompressed state, the second switch 820 and the third switch 822 are both in the disconnected state, and when the user puts the suction cup 611 in contact with the surface of the object and presses the contact convex point 3 in the middle of the bottom, the second switch 820 is triggered. At this time, the air pump 819 starts to work, and the gas inside the suction cup 611 is extracted through the suction pipe 211, so that a negative pressure is formed inside the suction cup 611. As the gas is extracted, the air pressure inside the suction cup gradually decreases, and at the same time, the push rod 821 is pushed inward, so that the push rod 821 contacts the third switch 822. When the air pressure reaches the predetermined value, the air pump 819 stops pumping air. When air infiltrates, the third switch 822 is disconnected, and the air pump starts pumping air, and the cycle is repeated.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
