[0030] The typical implementation mode embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes on different embodiments, which are all within the scope of the present application, and the description and drawings in essence are for illustration, not for limiting the present application.

[0031] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of direction or position relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. When these elements are in the position shown in the drawings, these descriptions are appropriate. If the position of these elements changes, the indication of these directions also changes accordingly.

[0032] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0033] The existing support mainly has a magnetic support and a clamping support, the magnetic support needs to paste a magnet sheet on an object, and the object is fixed through the magnetic attraction force of the support and the magnet sheet on the object, the support needs to be aligned with the magnet sheet during use, and the adsorption force of the magnetic support is small, and the magnetic support cannot be applied to other equipment with large mass. And the clamping support usually needs to be operated by both hands or needs to slide the object laterally when taking and placing the object, which is easy to cause inconvenience.

[0034] In addition, it should be noted that since the portable mobile device needs to be frequently moved to different positions during use, and in the existing support, the base of the support needs to be placed flat or fixed before clamping the device. This use mode needs to place the support on a flat supporting surface or clamp the support in a specific position to ensure that the support can support the mobile device. Therefore, the existing support has the problems of inconvenience in use and the like during use. Therefore, a connecting suction cup is proposed to solve the above problems.

[0035] The scheme is further illustrated by the following embodiments:

[0036] Figure 1 is a schematic view of the connecting suction cup of the present application. Figure 2 is Figure 1 is a sectional view of the connecting suction cup of Figure 3 is Figure 2 is an enlarged view of A of

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 , the connecting sucker of the embodiment is connected between two objects to be used as a support. For example, one end of the connecting sucker is connected to a wall or a desktop, and the other end is connected to a mobile device such as a mobile phone, a tablet or a photographic device, so that the mobile device can be fixed and the use of the device is facilitated. Of course, the connecting sucker can also be used to fix a mirror, a book, etc.

[0038] Specifically, the connecting sucker can include a main body 10, a negative pressure assembly 30 and two suckers 20. The main body 10 can be provided with a mounting cavity 11 inside, and the two ends of the main body 10 in the axial direction are provided with mounting portions 12, and the two suckers 20 are respectively mounted on the two mounting portions 12 of the main body 10 in the axial direction, and the opening directions of the two suckers 20 are opposite to each other, so that the two suckers 20 can be respectively adsorbed on the surfaces of two objects, so that the sucker 20 can be connected with the objects. The surfaces of the two objects are respectively located on the opposite sides of the main body 10.

[0039] The negative pressure assembly 30 is installed in the mounting cavity 11 and communicates with the two suckers 20. The negative pressure assembly 30 is used to provide negative pressure, so that under the driving of the negative pressure assembly 30, the sucker 20 can be adsorbed on the surface of the object, so that the sucker 20 can be stably connected with the object, avoiding the separation of the sucker 20 from the object, and then realizing the clamping of the object.

[0040] In the embodiment, the main body 10 can include a first shell 13 and a second shell 14, and the second shell 14 can be connected to the first shell 13 and enclose the mounting cavity 11. It should be noted that the side of the first shell 13 opposite to the second shell 14 is formed with the mounting portion 12, and the second shell 14 is also formed with the mounting portion 12, so that the two ends of the main body 10 in the axial direction are both formed with the mounting portion 12, and the structures of the two mounting portions 12 are the same, that is, the structures of the mounting portion 12 on the first shell 13 and the mounting portion 12 on the second shell 14 are the same.

[0041] Figure 4 is an exploded view of the connecting sucker of Figure 1 .

[0042] Please refer to Figure 2 and Figure 4The suction disc 20 can be provided with a suction through hole 21, and the mounting portion 12 is provided with a mounting through hole 121, and the mounting through hole 121 is communicated with the mounting cavity 11. At the same time, the suction disc 20 is mounted on the side of the mounting portion 12 away from the mounting cavity 11, and after the suction disc 20 is mounted on the mounting portion 12, the suction through hole 21 and the mounting through hole 121 are communicated to form a negative pressure channel 22. The negative pressure assembly 30 is communicated with the negative pressure channel 22, so that the negative pressure assembly 30 can provide negative pressure to the suction disc 20 through the negative pressure channel 22, so that the suction disc 20 can be adsorbed on the surface of the object through the negative pressure, and the connection between the suction disc 20 and the object is ensured.

[0043] It should be noted that the side of the suction disc 20 away from the mounting portion 12 is a suction portion 201, and the suction portion 201 has a certain curvature, so that when the suction disc 20 is attached to the surface of the object, the suction portion 201 can form a suction cavity with the surface of the object. When the air pressure in the suction cavity is reduced or vacuumized, the suction portion 201 can be attached to the surface of the object, so that the suction disc 20 is connected to the surface of the object.

[0044] In addition, since the connection between the suction disc 20 and the object is connected by negative pressure adsorption, and the negative pressure of the suction disc 20 is provided by the negative pressure assembly 30, under the continuous negative pressure provided by the negative pressure assembly 30, the suction disc 20 can be stably connected to the surface of the object, and the stable connection between the suction disc 20 and the object is ensured. In addition, when the negative pressure assembly 30 stops providing negative pressure to the suction disc 20, the suction disc 20 can be separated from the object, so that the separation of the object and the connected suction disc is facilitated, and the use of the connected suction disc is facilitated.

[0045] In addition, in the embodiment, the suction disc 20 can be made of flexible material, such as liquid silicone, flexible plastic, etc.

[0046] Referring to Figure 2 , Figure 3 and Figure 4 , the connected suction disc can further include a mounting piece 40 and a plunger piece 50.

[0047] The mounting piece 40 is connected to the side of the mounting portion 12 facing the mounting cavity 11, and a containing cavity 41 is formed between the mounting piece 40 and the mounting portion 12. In the embodiment, the negative pressure assembly 30 is communicated with the negative pressure channel 22 through the containing cavity 41.

[0048] Simultaneously, the plunger 50 is housed within the receiving cavity 41 and the negative pressure channel 22. Specifically, the mounting member 40 abuts against one end of the plunger 50 to limit its movement and prevent it from detaching from the negative pressure channel 22. In this embodiment, the plunger 50 can be used to control the opening and closing of the negative pressure assembly 30 and the negative pressure channel 22, thereby ensuring that the passage between the negative pressure assembly 30 and the negative pressure channel 22 remains open or closed. When the passage between the negative pressure assembly 30 and the negative pressure channel 22 is open, the negative pressure assembly 30 can provide negative pressure to the suction cup 20.

[0049] Figure 5 yes Figure 1 An exploded view of the second housing that connects to the suction cup. Figure 6 yes Figure 1 A schematic diagram of the plunger component connecting the suction cup.

[0050] See Figure 2 , Figure 5 and Figure 6 The plunger 50 may include a connected column portion 51 and an elastic portion 52, and the radial dimension of the elastic portion 52 is greater than the radial dimension of the column portion 51.

[0051] In this embodiment, the column portion 51 is housed within the negative pressure channel 22, and the end of the column portion 51 away from the elastic portion 52 extends out of the suction through hole 21. When the suction cup 20 is attached to the surface of the object, the end of the column portion 51 can abut against the surface of the object and drive the column portion 51 to move. The end of the elastic portion 52 facing the column portion 51 in the axial direction can abut against the inner wall of the mounting portion 12 facing the mounting cavity 11 to cut off the communication between the receiving cavity 41 and the negative pressure channel 22. That is, when the elastic portion 52 abuts against the inner wall of the mounting cavity 11, the elastic portion 52 can close the end of the negative pressure channel 22, thereby disconnecting the communication between the receiving cavity 41 and the negative pressure channel 22.

[0052] Meanwhile, the elastic part 52 can undergo elastic deformation. When the column part 51 moves axially relative to the main body 10, the column part 51 can drive the elastic part 52 to move away from the mounting part 12, so that the end of the elastic part 52 facing the column part 51 in the axial direction can separate from the inner wall of the mounting part 12, that is, the elastic part 52 separates from the inner wall of the mounting cavity 11, so that the receiving cavity 41 and the negative pressure channel 22 can be connected, thereby making the connection passage between the negative pressure assembly 30 and the negative pressure channel 22 connected.

[0053] It should be noted that, since the elastic part 52 can be elastically deformed, when the suction cup 20 is separated from the object, the elastic part 52 can drive the columnar part 51 to move away from the mounting cavity 11, so that the elastic part 52 can be reattached to the inner wall of the mounting cavity 11, that is, the elastic part 52 can reseal the end of the negative pressure channel 22, so that the negative pressure channel 22 is disconnected from the accommodation cavity 41 or the negative pressure assembly 30.

[0054] In this embodiment, the elastic part 52 can be made of elastic rubber, so as to ensure that the elastic part 52 can be elastically deformed and attached to the inner wall of the mounting cavity 11, and can achieve a sealing effect.

[0055] Referring to Figure 3 , Figure 5 and Figure 6 , the mounting part 12 is provided with an annular protrusion 122 on the side facing the mounting cavity 11, and the elastic part 52 is provided with an annular groove 521 and an abutting section 522. Wherein, the annular groove 521 is matched with the annular protrusion 122, so that the annular protrusion 122 can be clamped in the annular groove 521.

[0056] In this embodiment, the annular groove 521 can divide the accommodation cavity 41 into a first air chamber 531 and a second air chamber 532. Specifically, the first air chamber 531 is formed by the inner wall of the accommodation cavity 41 and the outer side wall of the annular groove 521, and the second air chamber 532 is formed by the inner wall of the mounting part 12, the inner wall of the annular protrusion 122, and the axial outer side wall of the annular groove 521 and the abutting section 522.

[0057] In addition, the first air chamber 531 can be in communication with the negative pressure assembly 30, and the second air chamber 532 can be in communication with the negative pressure channel 22. Specifically, the abutting section 522 is located in the second air chamber 532, and the abutting section 522 can abut or separate from the inner wall of the mounting part 12, so that the abutting section 522 can control the conduction or shutdown of the second air chamber 532 and the negative pressure channel 22, that is, the elastic part 52 can control the shutdown or conduction of the negative pressure channel 22 and the accommodation cavity 41 or the negative pressure assembly 30.

[0058] In addition, the annular protrusion 122 and the annular groove 521 are both provided with a negative pressure through hole 53, so that the first air chamber 531 and the second air chamber 532 are in communication through the two negative pressure through holes 53.

[0059] Referring to Figure 2 and Figure 4 , the negative pressure assembly 30 can include a gas pump 31, a negative pressure pipeline 32, and a pressure relief valve 33.

[0060] Wherein, the gas pump 31 is in communication with the two negative pressure channels 22 through the negative pressure pipeline 32, so that the gas pump 31 can provide negative pressure for the two suction cups 20 at the same time.

[0061] The pressure relief valve 33 is communicated on the negative pressure pipeline 32 and located between the air pump 31 and the negative pressure passage 22 to control the negative pressure in the negative pressure pipeline 32, thereby controlling the suction cup 20 to be adsorbed on the object or separated from the object.

[0062] It should be noted that when the pressure relief valve 33 is opened, the pressure in the negative pressure pipeline 32 and the pipeline communicated between the negative pressure pipeline 32 and the negative pressure passage 22 is restored to the normal pressure state, so that the suction cup 20 can be separated from the object, thereby facilitating the separation of the object from the connected suction cup.

[0063] In addition, in the embodiment, the pressure relief valve 33 is communicated to the outside of the main body 10 to facilitate user operation and improve the use experience of the connected suction cup.

[0064] Referring to Figure 3 In the embodiment, the negative pressure pipeline 32 is communicated to the first air chamber 531, and the first air chamber 531 is communicated to the second air chamber 532 through the negative pressure through hole 53, and the second air chamber 532 is communicated to the negative pressure passage 22, so that the air path between the negative pressure assembly 30 and the suction cup 20 is as shown in the air path 1 of Figure 3 , that is, the negative pressure pipeline 32 is communicated to the first air chamber 531 of the accommodating cavity 41, the first air chamber 531 is communicated to the negative pressure through hole 53 of the annular protrusion 122 through the negative pressure through hole 53 on the annular groove 521, the negative pressure through hole 53 of the annular protrusion 122 is communicated to the second air chamber 532, and the second air chamber 532 is communicated to the negative pressure passage 22, thereby forming a complete air path.

[0065] Figure 8 is another schematic view of the connected suction cup. Figure 1 is a cross-sectional view of the connected suction cup. Figure 9 is a cross-sectional view of the connected suction cup. Figure 8 is a cross-sectional view of the connected suction cup. Figure 10 is a cross-sectional view of the connected suction cup. Figure 8 is a cross-sectional view of the connected suction cup.

[0066] Referring to Figure 8 , Figure 9 and Figure 10 , the negative pressure assembly 30 can include two air pumps 31, two negative pressure pipelines 32 and two pressure relief valves 33. Among them, each air pump 31 is communicated to the negative pressure passage 22 at one end of the main body 10 through one negative pressure pipeline 32, so as to provide negative pressure for the suction cup 20 installed at the end, that is, each suction cup 20 is driven by one air pump 31 to ensure that the suction cup 20 can work independently.

[0067] At the same time, the two pressure relief valves 33 are arranged in one-to-one correspondence with the two negative pressure pipelines 32, so that each pressure relief valve 33 can independently control the negative pressure in the corresponding negative pressure pipeline 32, thereby ensuring that the suction cup 20 can be controlled independently and facilitating the use of the connected suction cup.

[0068] It should be noted that the two pressure relief valves 33 are both communicated to the outside of the main body 10, so that the operator can independently control the on or off of the pressure relief valve 33.

[0069] In addition, the negative pressure assembly 30 can also include a partition plate 34. Among them, the partition plate 34 is installed in the installation cavity 11 for installing the air pump 31, the negative pressure pipeline 32 and the pressure relief valve 33, so that the air pump 31, the negative pressure pipeline 32 and the pressure relief valve 33 form a group of negative pressure driving assemblies. It should be noted that the partition plate 34 can be provided with two, so that the two groups of negative pressure driving assemblies can be independently arranged on one partition plate 34. Of course, when the partition plate 34 is only one, the two groups of negative pressure driving assemblies can also be installed on the opposite two sides of the partition plate 34.

[0070] Figure 7 is Figure 1 a schematic view of the mounting portion of the connecting suction disc.

[0071] Referring to Figure 3 , Figure 5 and Figure 7 , the side of the mounting portion 12 away from the installation cavity 11 is provided with a sealing groove 123, and the sealing groove 123 is annularly arranged and located on the outer circumferential side of the mounting through hole 121. At the same time, the side of the suction disc 20 facing the main body 10 is provided with a sealing protrusion 23, and the sealing protrusion 23 is matched with the sealing groove 123, so that the sealing protrusion 23 can be clamped in the sealing groove 123, thereby ensuring the sealing of the negative pressure channel 22 and avoiding the pressure relief between the suction disc 20 and the mounting portion 12.

[0072] In this embodiment, the side of the mounting portion 12 away from the installation cavity 11 is provided with a connecting groove 124, and the side of the suction disc 20 facing the main body 10 is provided with a connecting protrusion 24, and the connecting protrusion 24 is clamped in the connecting groove 124, so that the suction disc 20 is connected in the mounting portion 12, and the stability of the connection between the suction disc 20 and the mounting portion 12 is ensured.

[0073] It should be noted that the connecting suction disc can also be provided with a battery assembly and a control module. Among them, the battery assembly and the control module are both installed in the installation cavity 11, and the battery assembly can provide power for the negative pressure assembly 30 to drive the negative pressure assembly 30 to work. The control module is used to control the opening or closing of the negative pressure assembly 30.

[0074] In this embodiment, the opening of the negative pressure assembly 30 can include various ways, for example:

[0075] I. Mechanical trigger type;

[0076] The plunger 50 is connected to the starting button or operating lever of the air pump 31 through a mechanical structure. When an object exerts pressure on the plunger 50 or causes the plunger 50 to deform, the plunger 50 is displaced and pushes the starting button or operating lever, thereby starting the air pump 31.

[0077] II. Pressure sensing type:

[0078] A pressure sensor is arranged on the plunger 50. When the plunger 50 is deformed by pressure, the pressure is transmitted to the pressure sensor. The pressure sensor converts the pressure signal into an electric signal, which is transmitted to the control module of the air pump 31 through a circuit system. After receiving the signal, the control module determines whether the pressure reaches a preset starting threshold value. If yes, a starting instruction is sent, and the air pump 31 is started. Alternatively, gas pressure or hydraulic pressure is used for transmission. The plunger 50 is connected to a sealed cavity filled with gas or liquid through a mechanical structure. When the plunger 50 is pressed by external force, the gas pressure or hydraulic pressure in the cavity is increased. The change in gas pressure or hydraulic pressure is transmitted to a pressure switch or pressure relay through a pipeline. When the pressure reaches the set value of the pressure switch or pressure relay, the contact is closed, and the power circuit or control circuit of the air pump 31 is turned on, thereby starting the air pump 31.

[0079] III. Displacement sensing type:

[0080] A displacement sensor is arranged beside the plunger 50. When the plunger 50 is displaced by external force, the displacement sensor can detect the displacement change of the plunger 50 in real time and convert the displacement signal into an electric signal. The electric signal is transmitted to the control system of the pump. The control system determines whether to start the pump according to a preset displacement threshold value. Of course, the displacement of the plunger 50 can also be detected by using an optical sensor. That is, a light-shielding piece or a reflective piece is arranged on the plunger 50, and an optical emitter and an optical receiver are arranged at opposite positions. When the plunger 50 is not subjected to external force, the light emitted by the optical emitter can reach the optical receiver smoothly. When the plunger 50 is displaced by external force, the light-shielding piece or the reflective piece will shield or reflect the light, so that the light signal received by the optical receiver changes. The optical sensor converts the change in the light signal into an electric signal, which is transmitted to the control circuit of the air pump 31, thereby achieving the starting control of the air pump 31.
