[0023] The technical solutions of the present application will be described clearly and completely in conjunction with the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0025] Reference Figures 1-3 In one embodiment, a stand 100 for a portable electronic device includes a stand assembly 10, a base 20, a suction cup 30, a vacuum-pumping assembly 40, a pressure change detector 50 (see Figure 6 and Figure 7 ) and a connecting pipe 60 (see Figure 5 ). The stand assembly 10 is connected to the base 20. The suction cup 30 is connected to the base 20. The vacuum-pumping assembly 40, the pressure change detector 50 and the connecting pipe 60 are all arranged in the base 20, the base 20 and the suction cup 30 are both provided with through holes, and the through hole of the base 20 and the through hole of the suction cup 30 are communicated, the connecting pipe 60 and the through hole of the base 20 are communicated through the connecting pipe 60.

[0026] Through such a structure, the vacuum-pumping assembly 40 can pump away the air between the suction cup 30 and a plane (for example, a table top), so as to form a vacuum between the suction cup 30 and the plane, and the stand 100 can be firmly fixed on the plane by the vacuum negative pressure through the suction cup 30. The pressure change detector 50 can detect the pressure change between the suction cup 30 and the plane, and when the above-mentioned pressure change exceeds a preset value, the vacuum-pumping assembly 40 starts to work, so as to pump away the air between the suction cup 30 and the plane again. In this way, the stand 100 can be firmly fixed on the plane for a long time, avoiding the air slowly entering between the suction cup 30 and the plane to cause the stand 100 to be not firmly fixed.

[0027] In one embodiment, the stand assembly 10 includes a support rod 11 and a support disc 12, the bottom end of the support rod 11 is rotatably connected to the base 20, and the support disc 12 is rotatably connected to the top end of the support rod 11. Through such a structure, when needed, the support rod 11 and the support disc 12 can be rotated from the position shown in Figure 1 to a position substantially parallel to the top surface of the base 20, that is, the stand assembly 10 can be changed from the state shown in Figure 1 to a folded state, so that the stand 100 occupies less space.

[0028] In one embodiment, a damping member is arranged between the top end of the support rod 11 and the support disc 12, and / or between the bottom end of the support rod 11 and the base 20. For example, the damping member can be a wear-resistant ring 14 sleeved on the rotating shaft 13 connecting the bottom end of the support rod 11 to the base 20. The damping member is used to provide damping for the rotation of the support rod 11 relative to the base 20 and the rotation of the support disc 12 relative to the support rod 11, so that the support rod 11 is positioned at a desired position relative to the base 20, and the support disc 12 is positioned at a desired position relative to the support rod 11.

[0029] In one embodiment, the support disc 12 is in the shape of a circular ring, which can include a plurality of magnets. The portable electronic device (such as a mobile phone, a tablet computer, a notebook computer, etc.) with a metal shell can be attracted and attached to the support disc 12 by the magnetic force of the magnets.

[0030] In one embodiment, the base 20 includes a body 21 and a rotating outer disc 22 rotatably connected to the body 21, and the bottom end of the support rod 11 is rotatably connected to the rotating outer disc 22. In Figure 1 In the state shown, the rotating axis of the rotating outer disc 22 is substantially vertical, and the rotating axis of the support rod 11 relative to the rotating outer disc 22 is substantially horizontal.

[0031] In one embodiment, the body 21 includes a top cover 211 provided with a through hole 213, and a rotating inner disc 212 rotatably accommodated in the through hole 213 of the top cover 211, and the rotating outer disc 22 is attached to and fixed to the rotating inner disc 212.

[0032] With reference to Figure 3 and Figure 4 In one embodiment, the inner side of the through hole 213 of the top cover 211 is formed with a plurality of tooth grooves 214, and the support frame 100 further includes a resiliently loaded sliding block 215 slidably connected to the rotating inner disc 212, and the end of the resiliently loaded sliding block 215 can be accommodated in one of the plurality of tooth grooves 214. Through such a structure, when the end of the resiliently loaded sliding block 215 can be accommodated in one of the plurality of tooth grooves 214, the rotating inner disc 212 is positioned at a certain position relative to the top cover 211. When the user holds the support rod 11 to apply a torque to the rotating outer disc 22, the rotating outer disc 22 drives the rotating inner disc 212 to start rotating. In this process, the resiliently loaded sliding block 215 is pushed by the tooth groove 214 and shrinks inward. The above-mentioned characteristics of the resiliently loaded sliding block 215 make it move out of one tooth groove 214 and then move to another adjacent tooth groove 214 during the rotation of the rotating inner disc 212, and so on, until the rotating inner disc 212 stops rotating.

[0033] In one embodiment, a wear-resistant ring 23 is provided between the rotating outer disk 22 and the body 21. For example, the top cover 211 is also provided with a receiving hole 216 that communicates with the through hole 213 and has a diameter larger than that of the through hole 213, and the wear-resistant ring 23 is received in the receiving hole 216. The wear-resistant ring 23 is sandwiched between the rotating outer disk 22 and the body 21. The wear-resistant ring 23 can provide a damping effect and can also prevent water and dust.

[0034] In one embodiment, the pressure change detection element 50 is a pressure sensor, and the connecting pipe 60 is a three-way connecting pipe, that is, it has three interconnected connection ports, which are respectively connected to the through holes on the vacuum assembly 40, the pressure change detection element 50, the base 20, and the suction cup 30 (see...). Figure 6 vias 201 and Figure 3 (Through hole 31 in the middle). With this configuration, the air pressure change detection element 50 can monitor the air pressure inside the suction cup 30 in real time. As outside air slowly enters the space between the suction cup 30 and the supporting surface (e.g., a desktop), the air pressure in that space gradually increases. When the air pressure in that space exceeds a preset value, the air pressure change detection element 50 sends a signal to a control component 70 (e.g., a circuit board with a control chip). The control component 70 controls the vacuum pumping component 40 to start working, thereby removing the air from the space between the suction cup 30 and the supporting surface (e.g., a desktop) again, thus maintaining the vacuum state of that space. When the air pressure change detection element 50 detects that the space between the suction cup 30 and the supporting surface is in a vacuum state that meets the requirements, the air pressure change detection element 50 sends a signal to the control component 70, which controls the vacuum pumping component 40 to stop working.

[0035] refer to Figure 5 and Figure 6 In one embodiment, the vacuum assembly 40 includes a motor 41, a transmission assembly 42, and a cylinder 43. The transmission assembly 42 is connected to both the motor 41 and the cylinder 43. The transmission assembly 42 transmits motion from the motor 41 to the cylinder 43. Specifically, in one embodiment, the motor 41 is a rotary motor that outputs rotational motion via a motor shaft. The transmission assembly 42 includes a gear 421 fixed to the motor shaft of the motor 41 and a rack 422 meshing with the gear 421. The rack is connected to the piston of the cylinder 43. This gear-rack structure converts the rotational motion of the motor shaft into linear motion driving the piston. When the piston is pushed inward, air in the cylinder 43 is discharged to the external environment through an automatic vent valve; when the piston is pulled outward, the automatic vent valve closes, causing air to be evacuated from the space between the suction cup 30 communicating with the cylinder and the supporting surface (e.g., a tabletop).

[0036] refer to Figure 7In one embodiment, the air pressure change detector 50 is a Hall sensor, which is arranged in the control assembly 70. The base 20 further comprises a resilient member 81 and a magnetic member 82. The bottom end of the magnetic member 82 penetrates the base 20 and is connected to the suction disc 30. The two ends of the resilient member 81 abut against the rotating inner disc 212 and the magnetic member 82, respectively. When the air in the space between the suction disc 30 and the supporting surface (e.g. a table top) is pumped out, the suction disc 30 is elastically deformed. The elastic deformation causes the magnetic member 82 connected to the suction disc 30 to be in a first position. When the air from the outside gradually enters the space between the suction disc 30 and the supporting surface (e.g. a table top), the air pressure in the space gradually increases, causing the suction disc 30 to gradually recover from the deformation. This causes the magnetic member 82 in the state shown in FIG. 1 to gradually move upward. Since the magnetic member 82 is close to the air pressure change detector 50, the voltage output by the air pressure change detector 50 changes due to the change in the magnetic field strength. When the output voltage of the air pressure change detector 50 changes to a preset value, the control assembly 70 controls the vacuum pumping assembly 40 to start working, so as to pump out the air in the space between the suction disc 30 and the supporting surface (e.g. a table top) again, thereby maintaining the vacuum state of the space. When the output voltage of the air pressure change detector 50 indicates that the space between the suction disc 30 and the supporting surface is in a required vacuum state, the control assembly 70 controls the vacuum pumping assembly 40 to stop working. Figure 7

[0037] In one embodiment, the support 100 further comprises a trigger button 90 slidingly connected to the base 20. The vacuum pumping assembly 40 comprises a deflation valve. The end 91 of the trigger button 90 is opposite to the deflation valve. In a normal state, the deflation valve is in a closed state. When it is necessary to remove the support 100 from the supporting surface (e.g. a table top), a user can press the trigger button 90, causing the end 91 to trigger the deflation valve, so that the deflation valve changes from the closed state to an open state. In this way, the air from the outside enters the space between the suction disc 30 and the supporting surface (e.g. a table top) through the connection pipe, thereby allowing the user to easily remove the support 100 from the supporting surface (e.g. a table top).

[0038] Obviously, the above embodiments are merely exemplary and are not intended to limit the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary or possible to exhaust all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.​
