Description

Technical Field

[0001] The utility model relates to the field of vehicle accessories, in particular to a suction cup assembly and a suction cup bracket. Background Art

[0002] The car-mounted suction cup is a common car accessory used to mount cameras, mobile phones and other devices. For example, when you need to take photos outside the car, the suction cup can be fixed on the car window glass to meet your photography needs.

[0003] A car-mount suction cup typically consists of two parts: an extension arm and a base. The base is designed to attach to the vehicle's glass or other desired mounting surface, ensuring stability through a strong suction cup or adhesive. The extension arm is the key component for attaching and supporting devices like phones and cameras, and it often features an adjustable design to accommodate devices of varying sizes and shapes.

[0004] In related technologies, the base of a vehicle-mounted suction cup is often equipped with a press-type suction cup structure. This structure requires the user to press the exhaust push rod of the exhaust valve multiple times during fixed installation to ensure that the exhaust push rod is fixed in the standard position of the exhaust valve, thereby forming a sealed vacuum environment. During this process, the user needs to apply a certain amount of pressure to the base to ensure that the suction cup can adhere tightly to the installation surface. This operation method requires the user to apply multiple forces at the same time, which not only increases the complexity of the operation, but also makes the installation process less simple and affects the user experience.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] To achieve this, please refer to Figures 1 to 5The suction cup assembly includes a shell 21, a pneumatic system 22 and a suction cup 23. The suction cup 23 is connected to the shell 21, and the shell 21 is provided with a receiving chamber 21a; the pneumatic system 22 is provided in the receiving chamber 21a of the shell 21, and the suction cup 23 is provided with an adsorption air cavity 23A and a breathing air port 23b connected to the adsorption air cavity 23A. The pneumatic system 22 is connected to the adsorption air cavity 23A and the receiving chamber 21a through the breathing air port 23b;

[0031] The pneumatic system 22 is configured to control the exhaust of gas from the adsorption air chamber 23A through the breathing air port 23 b and the inhalation of gas into the adsorption air chamber 23A through the breathing air port 23 b.

[0032] In the technical solution of the present invention, the suction cup 23 includes a shell 21, a pneumatic system 22 and a suction cup 23. The pneumatic system 22 is controlled to quickly change the air pressure value of the adsorption air cavity 23A in the suction cup 23. Specifically, when the suction cup 23 needs to be fixed on the mounting surface, the pneumatic system 22 can discharge the gas in the adsorption air cavity 23A from the breathing air port 23b of the suction cup 23 until the air pressure value of the adsorption air cavity 23A is lower than that of the outside world; when the suction cup 23 needs to be removed, the exhaust action of the pneumatic system 22 is switched to the intake action, and the gas in the accommodating cavity 21a is exhaled into the adsorption air cavity 23A through the breathing air port 23b. In this way, the adsorption air cavity 23A is connected to the outside world, and the atmospheric pressure of the adsorption air cavity 23A is equal to the atmospheric pressure of the outside world. The suction cup 23 loses the compression constraint of the atmospheric pressure, and the user can remove the suction cup 23 from the mounting surface. The fixing and removal of the suction cup 23 are both automatically completed by the pneumatic system 22, reducing the complexity of the operation.

[0033] The suction cup assembly is used to be fixed on the required mounting surface, such as the surface of the window glass or the surface of the center console. Specifically, the suction cup assembly includes a shell 21, a pneumatic system 22, and a suction cup 23. The shell 21 is a hollow structure to form a accommodating cavity 21a, and the outer peripheral wall of the shell 21 has air holes and other structures, so that the accommodating cavity 21a can be connected to the outside world through the air holes on the outer peripheral wall. The accommodating cavity 21a can be used to fix part of the structure of the pneumatic system 22. The outer surface of the shell 21 is connected to the suction cup 23. In one embodiment, the accommodating cavity is provided with a plurality of studs so that the suction cup 23 can be The housing 21 is screwed together. In another embodiment, the suction cup 23 can be connected to the housing 21 with an adhesive. Of course, other means can also be used to connect the housing 21 to the suction cup 23. In order to achieve gas inhalation or discharge, the accommodating chamber 21a is provided with a pneumatic system 22. The two ends of the pneumatic system 22 are respectively connected to the breathing port 23b of the suction cup 23 and the accommodating chamber 21a. The breathing port 23b is connected to the adsorption chamber 23A. In one embodiment, the pneumatic system 22 includes a control module 221, a control valve, an air pump, a connecting air pipe and an air pressure detection element 2241. The air pressure detection element 2241 is connected to the suction cup 23. Component 2241 and control valve are electrically connected to control module 221, one end of the trachea is connected to the breathing air port 23b, and the other end is connected to an air port of the control valve. At the same time, at least one air port of the control valve can be connected to the accommodating chamber 21a, and the air pressure value of the adsorption air cavity 23A is detected in real time by the air pressure detection component 2241, thereby controlling whether the connected trachea discharges the air in the adsorption air cavity 23A or inhales air into the adsorption air cavity 23A. It can be understood that according to the real-time detection of the air pressure detection component 2241, at this time, the air pressure value of the adsorption air cavity 23A is in a dynamic state. Value, specifically, when the air pressure detection element 2241 detects that the adsorption air cavity 23A is in the exhaust air pressure area, the control module 221 drives the control valve and the air pump to exhaust. At this time, the air pressure in the adsorption air cavity 23A is discharged through the connecting air pipe and the breathing air port 23b. When equal pressure disassembly is required, the control module 221 can drive the control valve and the air pump to inhale, or the one-way valve can be used to connect the adsorption air cavity 23A, and the external gas enters the adsorption air cavity 23A through the connecting air pipe and the breathing air port 23b, thereby achieving the air pressure value of the adsorption air cavity 23A equal to the atmospheric pressure standard value.

[0034] It should be explained here that the control process of the "pneumatic system 22" has the following situations: (1) After the suction cup assembly is placed on any mounting surface, the cavity of the adsorption air cavity 23A is shielded by the mounting surface. When the suction cup 23 needs to be fixed, the pneumatic system 22 is controlled to extract the gas in the adsorption air cavity 23A through the breathing air port 23b to form a negative pressure cavity, so that the suction cup is pressed and fixed on the mounting surface by the atmospheric pressure. When the suction cup needs to be removed, the solenoid valve is controlled to connect the connecting air pipe. At the same time, the connecting air pipe is connected to the adsorption air cavity through the breathing air port. As mentioned above, the accommodating chamber 21a is not a sealed space, and it is connected to the external atmosphere. At this time, the gas automatically flows from the high-pressure accommodating chamber through the breathing air port 23b into the adsorption air cavity 23A, so that the air pressure value of the adsorption air cavity 23A is equal to the atmospheric pressure. Of course, the air inlet of the solenoid valve can also be exposed on the shell. At this time, the gas automatically flows from the high-pressure external space into the adsorption air cavity 23A. In this process, the solenoid valve only acts as a switch structure to control the conduction between the adsorption air cavity 23A and the atmosphere.

[0035] (2) After the suction cup assembly is placed on any mounting surface, the cavity of the adsorption air cavity 23A is shielded by the mounting surface. When the suction cup 23 needs to be fixed, the pneumatic system 22 is controlled to extract the gas in the adsorption air cavity 23A through the breathing air port 23b to form a negative pressure cavity, so that the suction cup is pressed and fixed on the mounting surface by atmospheric pressure. When the suction cup needs to be removed, the air pipe is connected by controlling the solenoid valve and the air pump. At this time, the air pump actively inhales air to allow the gas to flow into the adsorption air cavity 23A through the breathing air port 23b. It can be understood that the air inlet of the air pump can be in the accommodating cavity or exposed to the shell, which is not limited here. In this way, the active suction of the air pump can quickly pressurize the adsorption air cavity 23 so that the air pressure value of the adsorption air cavity 23A is equal to the atmospheric pressure.

[0036] In another embodiment, see Figure 4 Combined with Figure 3 The pneumatic system 22 includes a control module 221, an exhaust branch 222 and an intake branch 223. The control module 221, the exhaust branch 222 and the intake branch 223 are all located in the accommodating chamber 21a. The exhaust branch 222 and the intake branch 223 are electrically connected to the control module 221; the air path of the exhaust branch 222 is connected to the air path of the intake branch 223, the breathing air port 23b and the accommodating chamber 21a, and the air path of the intake branch 223 is connected to the breathing air port 23b and the accommodating chamber 21a.

[0037] In this embodiment, the exhaust branch 222 is used to exhaust the adsorption air cavity 23A, and the air intake branch 223 is used to inhale the adsorption air cavity 23A. At the same time, the air pipe of the exhaust branch 222 is connected to the air pipe of the air intake branch 223. In this embodiment, the suction cup has only one breathing air port 23b, and the breathing air port 23b is located on the side of the suction cup 23 connected to the shell 21. The air intake branch 223 connects the breathing air port 23b and the adsorption air cavity 23A. The air path of the air intake branch 223 is connected to the breathing air port 23b and the adsorption air cavity 23A by connecting the air intake branch 223. Specifically, when adsorption and fixation are required, the exhaust branch 222 exhausts air in the control module 221. When the air pressure value in the adsorption air cavity 23A reaches the preset value, the exhaust branch 222 no longer exhausts air. At this time, the air pressure value of the adsorption air cavity 23A is less than the standard atmospheric pressure, thereby realizing the adsorption and fixation of the suction cup; when isobaric disassembly is required, the control module 221 stops the exhaust branch 222 from working, and at the same time the air intake branch 223 works to inhale air, and the external gas enters the adsorption air cavity 23A from the accommodating cavity 21a, the air path of the air intake branch 223, and the breathing air port 23b in turn.

[0038] In one embodiment of the present invention, please refer to Figure 4 The exhaust branch 222 includes an exhaust valve 2221 and an exhaust branch pipe 2222 of the multi-port air pipe 24. The exhaust branch pipe 2222 connects the air inlet of the exhaust valve 2221 and the breathing air port 23b, and the air outlet of the exhaust valve 2221 connects to the accommodating cavity 21a; the exhaust valve 2221 is electrically connected to the control module 221.

[0039] In this embodiment, the suction cup includes an exhaust valve 2221 and a multi-port air pipe 24. The multi-port air pipe 24 is provided with an exhaust branch pipe 2222. The exhaust valve 2221 is a one-way valve to realize one-way ventilation. The two ends of the exhaust branch pipe 2222 are respectively connected to the air inlet and the breathing air port 23b of the exhaust valve 2221. The air outlet of the exhaust valve 2221 is connected to the adsorption air cavity 23A. In this way, under the control of the control module 221, the exhaust valve 2221 can suck out the gas in the adsorption air cavity 23A through the breathing air port 23b, and then discharge it from the air outlet of the exhaust valve 2221, so that the air pressure in the adsorption air cavity 23A is lower than the standard atmospheric pressure, thereby realizing adsorption and fixation.

[0040] In one embodiment of the present invention, please refer to Figure 4 The intake branch 223 includes an intake valve 2231 and an intake branch pipe 2232 of the multi-port air pipe 24. The intake branch pipe 2232 connects the exhaust branch pipe 2222 and the air outlet of the intake valve 2231. The air inlet of the intake valve 2231 connects to the accommodating chamber 21a. The intake valve 2231 is electrically connected to the control module 221.

[0041] In this embodiment, the suction cup includes an air inlet valve 2231 and a multi-port air pipe 24. The multi-port air pipe 24 is provided with an air inlet branch pipe 2232. The two ends of the air inlet branch pipe 2232 are respectively connected to the exhaust branch pipe 2222 and the air outlet of the air inlet valve 2231. The air inlet of the exhaust valve 2221 is connected to the accommodating chamber 21a. In this way, under the control of the control module 221, the air inlet valve 2231 is connected, and the gas can enter the air inlet valve 2231 through the air inlet of the air inlet valve 2231, and then enter the adsorption air cavity 23A from the air outlet of the air inlet valve 2231, the exhaust branch pipe 2222, and the breathing air port 23b in turn. In this way, the outside world is connected to the adsorption air cavity 23A, thereby realizing isobaric disassembly.

[0042] In one embodiment of the present invention, please refer to Figure 4 Combined with Figure 3 The pneumatic system 22 also includes an air pressure detection branch 224, which includes an air pressure detection element 2241 provided in the control module 221 and an air pressure detection branch 2242 of the multi-port air pipe 24, and the two ends of the air pressure detection branch 2242 are respectively connected to the breathing air port 23b and the air pressure detection element 2241.

[0043] In this embodiment, the suction cup includes an air inlet valve 2231 and a multi-port air pipe 24. The multi-port air pipe 24 is provided with an air pressure detection branch pipe 2242. One end of the air pressure detection branch pipe 2242 can be connected to the adsorption air cavity 23A by connecting to the breathing air port 23b, and the other end is connected to the air pressure detection element 2241. In this way, the air pressure detection element 2241 can directly detect the air pressure value of the adsorption air cavity 23A. The control module 221 controls the exhaust branch 222 or the exhaust branch 222 to work according to the real-time air pressure value, thereby realizing the adsorption fixation or isobaric disassembly of the suction cup.

[0044] In one embodiment of the present invention, please refer to Figure 4 Combined with Figure 3 The air pressure detection branch pipe 2242 is connected to the air intake branch pipe 2232.

[0045] In this embodiment, the air pressure detection branch pipe 2242 is connected to the air intake branch pipe 2232, and the air intake branch pipe 2232 is connected to the air intake branch pipe 2232, and the air intake branch pipe 2232 is fixed in the adsorption air cavity 23A by means of limiters such as screws or clips. At this time, the air pressure detection branch pipe 2242 is also fixed in the adsorption air cavity 23A to prevent the air pressure detection branch pipe 2242 from falling and bending due to gravity, thereby affecting the air pressure detection. It can be understood that because the air intake branch pipe 2232 is also connected to the exhaust branch pipe 2222, when the exhaust branch 222 is in working state, there is always gas in the adsorption air cavity 23A flowing to the air pressure detection element 2241, thereby detecting the air pressure value of the adsorption air cavity 23A when the suction cup is in a fixed adsorption state.

[0046] In one embodiment of the present invention, please refer to Figure 3 The control module 221 includes a control circuit board 2211 and a control panel 2212.

The control panel 2212 is provided on the shell 21 for user visual viewing. The control panel 2212 is provided with multiple control buttons 2213. The control buttons 2213 are electrically connected to the control circuit board 2211. The user presses different control buttons 2213 to issue different control instructions to the control circuit board 2211 to put the suction cup in different working states.

[0048] In one embodiment of the present invention, please refer to Figure 1 The control panel 2212 further includes an air pressure display screen 2214, which is configured to display the air pressure value of the adsorption air cavity 23A.

[0049] In this embodiment, the control panel 2212 also includes an air pressure display screen 2214, which is configured to display the air pressure value of the adsorption air cavity 23A. At the same time, the control panel 2212 is also provided with an indicator light. When the suction cup is in the exhaust state, the indicator light is always on or flashing.

[0050] In one embodiment of the present invention, please refer to Figure 1 and Figure 3 The shell 21 also includes a battery charging port 21a and a waterproof sealing rib 211. The battery charging port 21a is located on the outer peripheral side of the shell 21.
