Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, and in particular to a solar-powered electric suction cup. Background Technology

[0002] With the increasing prevalence of digital products in people's lives, such as mobile phones, camcorders, and action cameras, the types and scenarios of shooting are also increasing. When equipment needs to be fixed, it is generally secured using specialized mechanical clamps, or by using ordinary suction cups or electric suction cups to adhere to objects. Specialized mechanical clamps are relatively complex and time-consuming for users, and crucially, they are not universally applicable, only suitable for objects of specific shapes. Ordinary suction cups, when used for extended periods, will gradually lose their vacuum due to gas infiltration, causing objects to fall. Ordinary electric suction cups require charging, and in scenarios requiring long-term operation, they must either be constantly powered by an external power source or charged periodically, failing to maintain suction power continuously without an external power source. Currently available clamping products for fixing camera equipment do not meet the requirements of space-saving and ease of use. Utility Model Content

[0003] Based on this, in order to overcome the shortcomings of the existing technology, this utility model provides a solar-powered electric suction cup to solve the problems mentioned in the background technology. Users do not need an external power source, which affects the cleanliness of the space, nor do users need to worry about charging the suction cup to ensure that the suction cup can be in working condition for a long time.

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a solar electric suction cup, including a face cover, a bottom shell and a rubber suction cup. The bottom of the face cover is provided with a connecting post, the bottom wall of the bottom shell is provided with a screw hole, the rubber suction cup is provided with an annular embedded metal part, the top of the embedded metal part is provided with a screw hole, the connecting post is vertically aligned with the screw hole and the screw hole, and screws are used to fix the face cover, the bottom shell and the rubber suction cup by passing screws through the connecting post, the screw hole and the screw hole in sequence.

[0005] A slot is provided on one side wall of the bottom shell, on which a solar panel is attached. The solar panel has a buckle that engages with the slot. The bottom shell houses a PCB circuit board, a vacuum pump, a T-junction, a one-way valve, and a battery. The PCB circuit board is fixed to the bottom of the bottom shell. The solar panel is electrically connected to the battery, the battery is electrically connected to the PCB circuit board, and the PCB circuit board is electrically connected to the vacuum pump. A negative pressure sensor is located on the PCB circuit board. An air extraction hole is provided on the rubber suction cup. The bottom end of the T-junction is inserted into the air extraction hole. One side of the upper end of the T-junction is sealed to the air inlet of the negative pressure sensor using a flexible hose. The other side of the upper end of the T-junction is sealed to the air inlet of the one-way valve using a flexible hose. The air outlet of the one-way valve is sealed to the air inlet of the vacuum pump using a flexible hose. An air outlet is provided on the bottom shell wall, corresponding to the air outlet of the vacuum pump.

[0006] The rubber suction cup and embedded metal parts are integrally molded, manufactured using plastic molding processes such as injection molding and pressure injection. The embedded metal parts effectively prevent deformation of the top of the rubber suction cup under negative pressure adsorption, ensuring the stability of the rubber suction cup's adsorption. The solar panel can charge the built-in battery, which in turn powers the PCB circuit board and vacuum pump. In use, the rubber suction cup is adsorbed onto the smooth surface of the object to be adsorbed, such as a camera, mobile phone, or camcorder. The vacuum pump operates, and the gas inside the rubber suction cup flows sequentially along the vent, T-junction, one-way valve, and vacuum pump, finally escaping from the vent, maintaining a vacuum negative pressure state at the bottom of the rubber suction cup for adsorption and fixation. The one-way valve prevents airflow from flowing back into the rubber suction cup. The negative pressure sensor detects the internal air pressure of the rubber suction cup and transmits the detection information to the PCB circuit board.

[0007] Preferably, the top of the cover is provided with a 1 / 4 screw hole for connecting a bracket, such as a car mount, a camera mount, or an action camera mount, to facilitate the fixing of the electric suction cup.

[0008] Preferably, the bottom of the base shell is provided with a positioning post, and the top of the rubber suction cup is provided with a positioning hole. The positioning hole and the positioning post are inserted and positioned to facilitate positioning during assembly and effectively improve assembly efficiency.

[0009] Preferably, the PCB circuit board is equipped with a switch and a charging port, and the bottom shell is equipped with a button. The button is positioned corresponding to the switch and can be used for touch operation of the switch. The bottom shell is also equipped with a dust plug, which is inserted into the charging port.

[0010] In this design, the device is powered on by pressing and holding the button for two seconds.

[0011] If the vacuum pump is stopped, pressing the button will start the vacuum pump. The negative pressure sensor on the PCB circuit board will detect the air pressure inside the rubber suction cup. If the negative pressure value gradually decreases, it is in normal working mode. When it reaches the lower limit of the specified negative pressure value, it will stop and the system will enter sleep mode.

[0012] If the vacuum pump is stopped, pressing the button will start the vacuum pump. The negative pressure sensor on the PCB circuit board will detect the air pressure inside the rubber suction cup. If the negative pressure does not change significantly for a period of time, it is an abnormal working mode, and the vacuum pump and system will be shut down.

[0013] If the vacuum pump is in operation, pressing the button will stop the vacuum pump and put the system into sleep mode.

[0014] In sleep mode, pressing the button will activate the vacuum pump if the negative pressure inside the rubber suction cup is below the set lower limit, as detected by the negative pressure sensor.

[0015] In sleep mode, the negative pressure sensor checks the pressure inside the rubber suction cup every few seconds. When the detected pressure is higher than the upper limit but not within the tolerance range of 1 standard atmosphere, the vacuum pump is started and stops when the negative pressure is detected to the lower limit.

[0016] In sleep mode, the negative pressure sensor checks the pressure inside the rubber suction cup every few seconds. When the pressure is within the tolerance range of 1 standard atmosphere, the vacuum pump does not start. After that, it checks every few seconds. When the pressure is within the tolerance range of 1 standard atmosphere several times in a row, the system shuts down. You need to manually press and hold the button for two seconds to start working.

[0017] When the system is in sleep mode, its power consumption is very low. The current generated by the solar panel after receiving sunlight charges the internal battery through the charging circuit of the PCB circuit board. The charging power is greater than the power consumed by the system in sleep mode, which ensures the continuous working capability of the internal battery.

[0018] Preferably, the bottom wall of the rubber suction cup is provided with gas channels, which are connected to the air extraction hole. The gas channels are arranged in an alternating pattern at the bottom of the rubber suction cup to ensure that the gas at the bottom of the rubber suction cup is discharged.

[0019] Preferably, the bottom of the cover is provided with a pressure plate, the bottom of the pressure plate abutting against the top of the tee. During the assembly process, the bottom of the tee can be inserted into the air extraction hole through the pressure plate.

[0020] Preferably, a filter screen is fixedly connected to the bottom of the air extraction hole to effectively prevent impurities from entering and causing blockages, ensuring operational stability and extending the service life of the electric suction cup.

[0021] The beneficial effects of this utility model are:

[0022] The aforementioned solar-powered electric suction cup abandons the traditional mechanical structure for clamping and fixing photographic equipment. It uses an electric suction cup, making it compatible with various devices. Its simple structure and ease of use ensure long-term stable operation without frequent charging or the need for an external power source. The electric suction cup can be used on car mounts, photography mounts, and action camera mounts. It is particularly useful for car phone mounts, as users attach the mount to the windshield or center console. If an external power source is used, a charging cable is required, obstructing the driver's view and maintaining interior cleanliness. Without a power source, the electric suction cup's static power consumption causes the battery to gradually deplete, leading to a decrease in vacuum and potential detachment. Therefore, users need to charge it periodically. This invention, however, uses a solar panel. Because the solar panel's charging power exceeds the suction cup's static power consumption, it maintains sufficient battery power for the entire system for an extended period, ensuring a clean and tidy space without the need for an external power source.

[0043] like Figures 1 to 7 As shown, this utility model provides a solar-powered electric suction cup, including a face cover 1, a bottom shell 2, and a rubber suction cup 3. The bottom of the face cover 1 is provided with a connecting post 12, and the bottom wall of the bottom shell 2 is provided with a screw hole. The rubber suction cup 3 has an annular embedded metal part 31 inside, and the top of the embedded metal part 31 is provided with a screw hole 32. The connecting post 12 corresponds vertically to the screw hole and the screw hole 32. The face cover 1, the bottom shell 2, and the rubber suction cup 3 are fixed by screws passing through the connecting post 12, the screw hole, and the screw hole 32 in sequence.

[0044] A slot 23 is provided on one side wall of the bottom shell 2, and a solar panel 4 is snapped into the slot 23. A buckle 41 is provided on the solar panel 4, and the buckle 41 engages with the slot 23. The bottom shell 2 houses a PCB circuit board 5, a vacuum pump 6, a three-way valve 7, a one-way valve 8, and a battery 9. The PCB circuit board 5 is fixed to the bottom of the bottom shell 2. The solar panel 4 is electrically connected to the battery 9, the battery 9 is electrically connected to the PCB circuit board 5, and the PCB circuit board 5 is electrically connected to the vacuum pump 6. The circuit board 5 is equipped with a negative pressure sensor 53. The rubber suction cup 3 has an air extraction hole 34. The bottom end of the tee 7 is inserted into the air extraction hole 34. One side of the upper end of the tee 7 is sealed to the air inlet of the negative pressure sensor 53 with a hose. The other side of the upper end of the tee 7 is sealed to the air inlet of the one-way valve 8 with a hose. The air outlet of the one-way valve 8 is sealed to the air inlet of the vacuum pump 6 with a hose. The bottom shell 2 has an air outlet hole 25 on its wall, which corresponds to the air outlet of the vacuum pump 6.

[0045] The rubber suction cup 3 and the embedded metal part 31 are integrally molded and can be manufactured using plastic molding processes such as injection molding and pressure injection. The embedded metal part 31 effectively prevents the top of the rubber suction cup 3 from deforming under negative pressure adsorption, ensuring the stability of the rubber suction cup 3's adsorption. The solar panel 4 can charge the built-in battery 9, which in turn powers the PCB circuit board 5 and the vacuum pump 6. In use, the rubber suction cup 3 is adsorbed onto the smooth surface of the object to be adsorbed, such as a camera, mobile phone, or camcorder. The vacuum pump 6 operates, and the gas inside the rubber suction cup 3 flows sequentially along the suction hole 34, the three-way valve 7, the one-way valve 8, and the vacuum pump 6, finally being discharged from the exhaust hole 25, maintaining a vacuum negative pressure state at the bottom of the rubber suction cup 3 to complete the adsorption and fixation. The one-way valve 8 prevents airflow from flowing back into the rubber suction cup 3. The negative pressure sensor 53 is used to detect the internal air pressure of the rubber suction cup 3 and transmit detection information to the PCB circuit board 5.

[0046] Furthermore, the top of the cover 1 is provided with a 1 / 4 screw hole 11 for connecting a bracket, such as a car mount, a camera mount, or an action camera mount, to facilitate the fixing of the electric suction cup.

[0047] Furthermore, the bottom of the base shell 2 is provided with a positioning post 24, and the top of the rubber suction cup 3 is provided with a positioning hole 35.

[0048] Furthermore, the PCB circuit board 5 is provided with a switch 51 and a charging port 52, and the bottom shell 2 is provided with a button 21. The button 21 corresponds to the position of the switch 51 and performs touch operation on the switch 51. The bottom shell 2 is also provided with a dust plug 22, which is inserted into the charging port 52.

[0049] In this embodiment, the device is powered on by pressing and holding button 21 for two seconds.

[0050] If the vacuum pump 6 is stopped, press button 21 to start the vacuum pump 6. The negative pressure sensor 53 on the PCB circuit board 5 detects the air pressure inside the rubber suction cup 3. If the negative pressure value gradually decreases, it is in normal working mode. When it reaches the lower limit of the specified negative pressure value, it stops and the system enters sleep mode.

[0051] If vacuum pump 6 is in a stopped state, press button 21 to start vacuum pump 6. Negative pressure sensor 53 on PCB circuit board 5 detects the air pressure inside rubber suction cup 3. If the negative pressure does not change significantly for a period of time, it is an abnormal working mode, and vacuum pump 6 and system will be shut down.

[0052] If vacuum pump 6 is in operation, pressing button 21 will stop vacuum pump 6 and the system will enter sleep mode.

[0053] In sleep mode, when button 21 is pressed, the negative pressure sensor 53 detects that the negative pressure inside the rubber suction cup 3 is below the set lower limit, and starts the vacuum pump 6.

[0054] In sleep mode, the negative pressure sensor 53 checks the pressure inside the rubber suction cup 3 every few seconds. When the detected pressure is higher than the upper limit but not within the tolerance range of 1 standard atmosphere, the vacuum pump 6 is started until the negative pressure is detected to the lower limit.

[0055] In sleep mode, the negative pressure sensor 53 checks the pressure inside the rubber suction cup 3 every few seconds. When the pressure is within the tolerance range of 1 standard atmosphere, the vacuum pump 6 is not started. After that, it checks the pressure every few seconds. When the pressure is within the tolerance range of 1 standard atmosphere several times in a row, the system shuts down. You need to manually press and hold button 21 for two seconds to start working.

[0056] When the system is in sleep mode, its power consumption is very low. The current generated by the solar panel 4 after receiving sunlight charges the internal battery 9 through the charging circuit of the PCB circuit board 5. The charging power is greater than the power consumed by the system in sleep mode, which ensures the continuous working capability of the internal battery 9.

[0057] Furthermore, a gas flow channel 36 is provided on the bottom wall of the rubber suction cup 3. The gas flow channel 36 is connected to the air extraction hole 34. The gas flow channels 36 are arranged in an alternating pattern at the bottom of the rubber suction cup 3 to ensure that the gas at the bottom of the rubber suction cup 3 is discharged.

[0058] Furthermore, the bottom of the cover 1 is provided with a pressure plate 13, which abuts against the top of the tee 7. During the assembly process, the bottom of the tee 7 can be inserted into the air extraction hole 34 through the pressure plate 13.
