[0034] In the existing adsorption bracket, one end is usually adsorbed to the designated position by magnetic adsorption, and the other end fixes the object to be fixed by means of clamping, etc. However, the fixing method of magnetic adsorption means that the adsorption bracket and the designated position are only fixed by magnetic adsorption, and the adsorption strength is low. In addition, the adsorption bracket is easily affected by strong vibration and falls off, which affects the user experience.

[0035] Based on this, the utility model proposes an adsorption device, in which an adsorption chamber is provided on the side of the front shell facing away from the rear shell. In addition, a pneumatic source is placed in the accommodating chamber, and an air hole is provided on the front shell, through which the adsorption chamber and the pneumatic source can be connected; in this way, the pneumatic source can be used to evacuate air in the adsorption chamber, so that the adsorption chamber is in a negative pressure state, thereby generating a stronger adsorption force between the adsorption device and the position to be fixed on the vehicle, thereby improving the fixing strength of the two.

[0036] like Figure 1 - Figure 3 As shown, the adsorption device comprises:

[0037] The rear housing 100 has an accommodating cavity with an opening formed therein;

[0038] The pneumatic source 200 is fixed in the accommodating cavity;

[0039] The front shell 300 is covered at the opening to close the accommodating cavity. The front shell 300 is provided with an air hole 310, and a side of the front shell 300 away from the rear shell 100 is provided with an adsorption cavity 320, and the air hole 310 communicates the adsorption cavity 320 and the pneumatic source 200; and

[0041] The switch control component controls the opening or closing of the pneumatic source 200 so that the adsorption chamber 320 is in a negative pressure or normal pressure state.

[0042] In the technical solution adopted in this embodiment, a receiving cavity is formed inside the rear shell 100 of the device, and an opening is provided on the receiving cavity; in order to cover the receiving cavity, a front shell 300 is also provided at the opening, and the receiving cavity is closed by the cooperation of the front shell 300 and the rear shell 100. In order to improve the fixing strength of the article, an adsorption cavity 320 is provided on the side of the front shell 300 away from the rear shell 100. In addition, a pneumatic source 200 is placed in the receiving cavity, and an air hole 310 is also provided on the front shell 300, through which the adsorption cavity 320 and the pneumatic source 200 can be connected; in this way, the pneumatic source 200 can be used to evacuate the adsorption cavity 320, so that the adsorption cavity 320 is in a negative pressure state, thereby generating a strong adsorption force between the adsorption device and the position to be adsorbed, thereby improving the fixing strength of the two. In addition, a switch control component connected to the pneumatic source 200 is also provided in the accommodating chamber, wherein the switch control component can be used to control the opening or closing of the pneumatic source 200, so that the adsorption chamber 320 is in a negative pressure or normal pressure state, thereby realizing the fixing and separation of the adsorption device.

An adsorption chamber 320 is also provided on the side of the front shell 300 away from the rear shell 100. Preferably, the front shell 300 is recessed in the direction close to the accommodating chamber to form the adsorption chamber 320.

The arrangement of the sealing member 500 can produce excellent sealing between the adsorption chamber 320 and the position to be installed in the vehicle, ensure strong adsorption force, and avoid the problem of air leakage.

[0045] Optionally, in one embodiment of the utility model, a plurality of seals 500 are provided, and the plurality of seals 500 are stacked along the cavity wall of the adsorption chamber 320. This design arranges the plurality of seals 500 in a stacked manner along the cavity wall of the adsorption chamber 320 to form a solid defense line, which effectively prevents air leakage in the adsorption chamber 320 during the adsorption process, and the arrangement of the plurality of seals 500 makes the sealing performance more stable. It should be noted that there is no specific limitation on the shape of the seal 500, for example, it may be a sealing strip, or it may be a sealing ring, etc. Preferably, the sealing ring is an annular structure matching the adsorption chamber 320, and a plurality of sealing strips are arranged at intervals in the adsorption chamber 320. Further preferably, two or three sealing strips are arranged at the same position, and a plurality of sealing strips are stacked, which is beneficial to improving the sealing effect.

Preferably, in another embodiment, the button 700 is a touch sensing structure, for example, it can be a pressure sensor, or a gesture sensor, etc. In this way, the user only needs to approach or touch the button 700 with his hand, and the housing can easily open or close the switch control component, and the operation is convenient and quick.

[0048] Alternatively, if Figure 2 and Figure 3 As shown, in one embodiment of the utility model, the adsorption device also includes:

Specifically, when the mobile phone needs to be charged, it is only necessary to place the adsorption device on the rear shell 100 of the mobile phone, turn on the switch control component to start the pneumatic source 200, so that a negative pressure is formed in the adsorption cavity 320, and a strong adsorption force is generated with the mobile phone; after charging is completed, it is only necessary to turn off the switch control component to turn off the pneumatic source 200, so that the adsorption cavity 320 is restored to a normal pressure state, thereby detaching from the mobile phone. It should be noted that the battery 900 can be set at any position in the accommodating cavity.

[0052] Optionally, in an embodiment of the utility model, in order to enable the PCBA board 800 to adapt to the space in the accommodating cavity, the PCBA board 800 can be a rigid board or a flexible board. The PCBA board 800 is preferably a flexible board. The PCBA board 800 has the advantages of high wiring density, light weight, thin thickness and good bendability. It can be bent according to actual needs to adapt to the remaining space in the accommodating cavity, thereby reducing the occupied volume of the adsorption device and making it easy to carry.

[0053] Optionally, in an embodiment of the present invention, in order to conveniently control the opening or closing of the switch control element, a touch panel is further provided on the rear housing 100, and the switch control element and the PCBA board 800 are both electrically connected to the touch panel.

This method not only reduces the occupied space of the device, but also improves the reliability of the package. SIP technology can integrate chips with different functions such as processors, memories, interfaces, etc. into one package, effectively reducing the complexity of the circuit board; SOC technology is a design method that integrates the entire system on a single chip. This method realizes the complete system functions on a single chip, greatly reducing the size of the device. Through the highly integrated and superior SOC chip, the PCBA board 800 can achieve higher performance and lower power consumption; Chiplet chip design integration technology is an emerging chip design method. It disperses multiple functional modules on different chips, and then combines these chips together through advanced packaging technology to form a complete system.
