[0026] To facilitate understanding of the present invention, the present invention is described in more detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0027] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the technical field of this utility model. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] In the description of this application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship when the device or element is normally used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation at any time, unless otherwise specified herein.

[0029] Figures 1-10 An embodiment of the electric adsorption bracket of the present invention is shown, comprising a base 1, an electric adsorption mechanism 2 and a support mechanism 3, wherein a part of the electric adsorption mechanism 2 is arranged inside the base 1, and the other part is arranged at the lower end of the base 1, and the electric adsorption mechanism 2 is used to adsorb the base 1 on the contact plane and release the base 1 from the contact plane; the contact plane here includes a desktop, a wall, and other support surfaces for placing the bracket, which belongs to the use environment of the bracket. The support mechanism 3 is arranged at the upper end of the base 1, and the support mechanism 3 is used to support and fix the electronic device. The base 1 is adsorbed on the contact plane by electric adsorption, and the electric adsorption method is not easily affected by the external environment and causes the adsorption force to weaken, and the fixing effect is better; and each time the electric adsorption bracket is moved, it is only necessary to release the bracket by the electric adsorption mechanism 2 first, and then re-adsorb it. It is very convenient to release and fix the bracket each time. Specifically, combined with Figure 3-Figure 5 As shown, the electric adsorption mechanism 2 includes a suction cup 21, an air extraction component 22 and an air supply component 23. The suction cup 21 is arranged at the lower end of the base 1. An air hole 211 is provided on the suction cup 21. The suction cup 21 is made of a trumpet-shaped flexible material, such as soft plastic, rubber, etc. The suction cup 21 is used to seal the contact plane to form a closed space; the air extraction component 22 is arranged inside the base 1, and the air extraction component 22 includes an air extraction pipe 221. The air extraction pipe 221 is connected to the air hole 211. The air extraction component 22 is used to extract the air in the closed space through the air hole 211 to generate negative pressure in the closed space, so that the suction cup 21 is adsorbed on the contact plane under the action of the external atmospheric pressure; the air supply component 23 is used to supply air to the closed space to release the suction cup 21; the support mechanism 3 is arranged at the upper end of the base 1 away from the suction cup 21, and the support mechanism 3 is used to support and fix the electronic device.

[0030] In the present invention, when the electric adsorption bracket needs to be fixed, the contact plane is covered by the suction cup 21 to form a closed space. After the vacuum component 22 is actuated, the air in the closed space is extracted through the air hole 211 and the vacuum pipe 221, so that the closed space is in a vacuum state. The suction cup 21 is adsorbed on the contact plane, thereby fixing the bracket. After the vacuum component 22 completes the vacuuming and fixing, the internal vacuum motor stops running. There is no need for the motor to run all the time to maintain the vacuum state. Therefore, it has very low energy consumption and can be used for a long time even when powered by batteries. When the electric adsorption bracket needs to be moved, air is supplied to the closed space through the air supply component 23. The closed space in a vacuum state loses its adsorption force after air enters, and the suction cup 21 is released from the contact plane. When it is fixed again, the vacuum component 22 can be restarted, which is more convenient.

[0031] It should be noted that the above-mentioned contact plane can be a wall, a tabletop or a glass surface.

[0032] In some embodiments, combined Figure 1 and Figure 4 As shown, a battery 24 is provided inside the base 1, and a charging interface 25 is provided on the side of the base 1. The battery 24 is electrically connected to the vacuum component 22, and the charging interface 25 is electrically connected to the battery 24. The charging interface 25 can be a USB interface, a Type-c interface or a Lightning interface, etc. The charging interface 25 is used to charge the battery 24.

[0033] In some embodiments, as Figure 1 As shown, a power indicator light 26 is provided on the base 1 adjacent to the charging port 25. The power indicator light 26 is used to display the power status of the battery 24. For example, when the battery 24 is low on power, the power indicator light 26 emits red light to remind the user to charge; when the battery 24 is fully charged, the power indicator light 26 emits green light to remind the user that the battery 24 is fully charged.

[0034] In some embodiments, combined Figure 1 and Figure 4 As shown, the electric adsorption mechanism 2 also includes a control circuit board 27, which is electrically connected to the battery 24, the vacuum component 22 and the power indicator light 26 respectively. The control circuit board 27 is used to collect the power information of the battery 24 and control the operation of the power indicator light 26 according to the power information; the control circuit board 27 is also used to control the vacuum component 22 to stop working when the enclosed space reaches a vacuum.

[0035] In some embodiments, combined Figure 3 and Figure 9As shown, the electric suction mechanism 2 also includes a trigger switch 28. A portion of the trigger switch 28 is located inside the base 1. The suction cup 21 is provided with a through hole 11, and the other portion of the trigger switch 28 extends from the through hole 11. When the bracket is placed on the contact surface, the trigger switch 28 is configured to move along the through hole 11 toward the base 1 to trigger the operation of the suction assembly 22. When the trigger switch 28 is subjected to an external force, the trigger switch 28 moves along the through hole 11 toward the base 1, triggering the operation of the suction assembly 22. After the suction assembly 22 is activated, it begins to extract the air in the enclosed space through the air hole 211.

[0036] Specifically, such as Figure 9 As shown, the triggering principle of the trigger switch 28 is as follows: a first conductive sheet 29 is provided at the end of the trigger switch 28 away from the suction cup 21, the first conductive sheet 29 is electrically connected to the battery 24, and the vacuum component 22 is electrically connected to the second conductive sheet 20. When the trigger switch 28 moves along the through hole 11 toward the direction close to the base 1, the first conductive sheet 29 contacts the second conductive sheet 20, and the battery 24 and the vacuum component 22 are conductive to supply power to the vacuum component, and the vacuum component 22 starts to move.

[0037] The end of the trigger switch 28 away from the base 1 can be higher or lower than the end of the suction cup 21 away from the base 1, or can be flush with the end of the suction cup 21 away from the base 1.

[0038] In some embodiments, as Figure 3 and Figure 4 As shown, the end of the trigger switch 28 away from the base 1 is lower than the end of the suction cup 21 away from the base 1. When the electric adsorption bracket is placed on the contact plane, since the end of the trigger switch 28 away from the base 1 is lower than the end of the suction cup 21 away from the base 1, the trigger switch 28 first contacts the contact plane, and the electric adsorption bracket continues to sink due to its own weight and moves toward the contact plane. At the same time, after the trigger switch 28 contacts the contact plane, it automatically moves along the through hole 11 toward the base 1, triggering the action of the vacuum component 22. At the same time, the suction cup 21 also continues to approach the contact plane and eventually covers the contact plane to form a closed space. The vacuum component 22 extracts the air in the closed space, causing the suction cup 21 to be adsorbed on the contact plane.

[0039] In some embodiments, the central axis of the trigger switch 28, the central axis of the suction cup 21, and the central axis of the base 1 all coincide. Because the central axis of the trigger switch 28 and the central axis of the suction cup 21 coincide, there is no gap between the suction cup 21 and the contact surface due to the presence of the trigger switch 28 during the suction process, resulting in a better suction effect. Because the central axis of the suction cup 21 coincides with the central axis of the base 1, the base 1 does not tilt during suction, resulting in a better suction effect.

[0040] In some embodiments, combined Figure 5 、 Figure 6 and Figure 10 As shown, the vacuum assembly 22 includes a vacuum chamber 222, a piston rod 223, and a drive motor 224. The vacuum chamber 222 is connected to the vacuum pipe 221. The piston rod 223 is located in the vacuum chamber 222. The drive motor 224 is connected to the piston rod 223. The drive motor 224 is used to drive the piston rod 223 to move back and forth in a straight line to extract the air in the enclosed space. The drive motor 224 drives the piston rod 223 to move back and forth in a straight line, continuously compressing the air in the vacuum chamber 222. Since the vacuum pipe 221 is connected to the vacuum chamber 222, the air in the enclosed space is drawn into the vacuum chamber 222 via the vacuum pipe 221. Finally, all the air in the enclosed space is extracted, reaching a vacuum state. The suction cup 21 is adsorbed onto the contact surface, and the fixing effect is better.

[0041] It should be noted that there are many ways in which the drive motor 224 can drive the piston rod 223 to achieve linear reciprocating motion, such as utilizing a crank slider structure, a cam structure, or an eccentric wheel structure. In this embodiment, the output end of the drive motor 224 is connected to the eccentric wheel 225, and the end of the piston rod 223 near the driving member is provided with an opening 2231 that is compatible with the eccentric wheel 225. The drive motor 224 drives the eccentric wheel 225 to rotate, and the eccentric wheel 225 moves within the opening 2231, converting the rotational motion of the eccentric wheel 225 into linear reciprocating motion of the piston rod 223.

[0042] In some embodiments, combined Figure 5 、 Figure 6 and Figure 10 As shown, the exhaust chamber 222 includes a compression chamber 2221 and a closed chamber 2222, the piston rod 223 is located inside the compression chamber 2221, the exhaust pipe 221 is connected to the closed chamber 2222, the closed chamber 2222 has a connecting port 2223 connected to the compression chamber 2221, and a first sealing member 225 is provided at the connecting port 2223. The first sealing member 225 can be a sealing plug, and the first sealing member 225 is used to seal or open the connecting port 2223.

[0043] The air supply component 23 can be implemented in a variety of ways. For example, the air supply component 23 can be an air pump that directly supplies air into the enclosed space, or the air supply component 23 can be a mechanical vacuum breaking valve.

[0044] In some embodiments, combined Figure 5 、 Figure 6 and Figure 10As shown, the sealed cavity 2222 has an air inlet 2224, and the air supply assembly 23 includes an air supply button 231, an elastic member 232, and a second sealing member 233. One end of the air supply button 231 is exposed to the base 1, and the other end is connected to the second sealing member 233. The second sealing member 233 can be a sealing plug, and the elastic member 232 can be a spring, a memory alloy, or a bellows. The elastic member 232 is connected to the air supply button 231 and is used to drive the second sealing member 233 to block the air inlet 2224. The air supply assembly 23 has a simple structure and can achieve one-button unlocking of the suction cup 21 by cooperating with the air supply assembly 23, which is easy to operate.

[0045] The following combination Figure 5 、 Figure 6 and Figure 10 The principles of air extraction and air supply are explained in detail.

[0046] When the air extraction assembly 22 is activated, the piston rod 223 moves back and forth in a straight line along the compression chamber 2221 driven by the driving motor 224. When the piston rod 223 is extracted from the compression chamber 2221, the generated air flow pushes the first sealing member 225 away from the connecting port 2223, and the compression chamber 2221 is connected with the sealed chamber 2222. The air in the sealed space is drawn into the compression chamber 2221 through the air extraction pipe 221. Then, as the piston rod 223 pushes toward the interior of the compression chamber 2221, the generated air flow pushes the first sealing member 225 away from the connecting port 2223. The first sealing member 225 re-seals the connecting port 2223, and at the same time, the air drawn into the compression chamber 2221 from the enclosed space is discharged from the first air outlet 2225 of the compression chamber 2221, and then the air is discharged to the outside of the exhaust chamber 222 through the second air outlet 2227 of the exhaust chamber 2226, thereby continuously circulating until the enclosed space reaches a vacuum, and the first sealing member 225 re-seals the connecting port 2223. At this time, the enclosed chamber 2222, the suction pipe 221 and the enclosed space are all in a vacuum state.

[0047] The second sealing member 233 will be subjected to the force of the elastic member 232, so that the second sealing member 233 always blocks the air inlet 2224. When the air supply button 231 is pressed, since the air supply button 231 is connected to the second sealing member 233, the elastic member 232 will be squeezed so that the second sealing member 233 no longer blocks the air inlet 2224. Air enters the closed cavity 2222 from the air inlet 2224, breaking the vacuum state of the closed cavity 2222, the suction tube 221 and the closed space, and the suction cup 21 is released from the contact plane.

[0048] In some embodiments, as Figure 4As shown, the base 1 includes an upper shell 12 and a lower shell 13. The upper shell 12 and the lower shell 13 are detachably connected. There are many ways of detachable connection, such as snap connection, threaded connection or pin connection, etc. The detachable connection between the upper shell 12 and the lower shell 13 makes it more convenient to repair the equipment inside the base 1.

[0049] In some embodiments, as Figure 4 and Figure 5 As shown, the interior of the base 1 is provided with a first mounting bracket 14 and a second mounting bracket 15. The first mounting bracket 14 and the second mounting bracket 15 are detachably connected. There are many ways to detachably connect them, such as by snapping, threading, or pinning. In this embodiment, a threaded connection is used. The exhaust chamber 222, piston rod 223, and drive motor 224 are located between the first mounting bracket 14 and the second mounting bracket 15. The first mounting bracket 14 and the second mounting bracket 15 secure and protect the exhaust chamber 222, piston rod 223, and drive motor 224, and rationally utilize the space within the base 1, reducing the size of the base 1. When maintenance is required, the first mounting bracket 14 and the second mounting bracket 15 can be simply disassembled.

[0050] In some embodiments, as Figure 4 As shown, the first mounting bracket 14 is provided with a first limiting groove 141 adapted to the piston rod 223, and the second mounting bracket 15 is correspondingly provided with a second limiting groove 151. The end of the piston rod 223 close to the driving motor 224 is respectively stuck in the first limiting groove 141 and the second limiting groove 151, and can move back and forth in a straight line along the first limiting groove 141 and the second limiting groove 142. The first limiting groove 141 and the second limiting groove 142 play a limiting role on the piston rod 223, which can improve the stability of the piston rod 223 during linear reciprocating motion.

[0051] In some embodiments, as Figure 2 As shown, support mechanism 3 includes a rotating assembly 31 and a fixed assembly 32. Rotating assembly 31 is located at the end of base 1 away from suction cup 21 and is rotatably connected to base 1. Fixed assembly 32 is connected to rotating assembly 31, and fixed assembly 32 is used to secure the electronic device. Rotating assembly 31 can drive fixed assembly 32 to rotate, making it more flexible and convenient to adjust the position of the electronic device, and has a wider range of application scenarios.

[0052] In some embodiments, as Figure 7As shown, a rotating shaft 16 is provided at one end of the base 1 away from the suction cup 21. The rotating assembly 31 includes a rotating base 311. The rotating base 311 is sleeved around the outer periphery of the rotating shaft 16 and can rotate relative to the rotating shaft 16. By sleeved around the outer periphery of the rotating shaft 16, the rotating base 311 can rotate 360 degrees, which facilitates the adjustment of the position of the electronic device and provides greater flexibility.

[0053] In some embodiments, as Figure 7 As shown, the rotating assembly 31 further includes a rotating connector 312, the rotating seat 311 is sleeved on the rotating connector 312, and the rotating connector 312 is sleeved on the rotating shaft 16. By arranging the rotating connector 312 between the rotating seat 311 and the rotating shaft 16, the rotating seat 311 can rotate relative to the rotating shaft 16 along with the rotating connector 312, making the rotation process more stable.

[0054] In some embodiments, as Figure 7 As shown, the rotating shaft 16 is also provided with a gear 313, which can rotate relative to the rotating shaft 16 along with the rotating base 311. The rotating assembly 31 also includes a bent member 314, which is disposed adjacent to the gear 313 and has a tip 3141 that contacts the gear 313. When the gear 313 rotates, the gear 313 continuously collides with the tip 3141 of the bent member 314, generating a sound that provides audio feedback to the user, enhancing the user experience.

[0055] In some embodiments, combined Figure 7 and Figure 8 As shown, the fixed assembly 32 includes a connecting plate 321 and a fixed housing 322. The connecting plate 321 is hinged to the rotating assembly 31, and the fixed housing 322 is slidably connected to the connecting plate 321. The connecting plate 321 is hinged to the rotating assembly 31, so that the fixed housing 322 can swing relative to the rotating assembly 31 along with the connecting plate 321. At the same time, the fixed housing 322 is also slidably connected to the connecting plate 321. The fixed housing 322 can also be extended and retracted relative to the connecting plate 321, further changing the position of the fixed housing 322, that is, the position of the electronic device, making it more convenient to use and having a wider range of application scenarios. Figure 2 As shown, when the electronic device needs to be fixed, the fixing component 32 can be unfolded; Figure 1 As shown, when the electronic device does not need to be fixed, the fixing component 32 can be retracted to occupy less space and be convenient to carry.

[0056] Specifically, such as Figure 8As shown, the fixed shell 322 includes a detachably connected end cover 3221, a first mounting shell 3222 and a second mounting shell 3223. The second mounting shell 3223 is provided with a slide groove 3224 that is compatible with the connecting plate 321. The connecting plate 321 is located in the slide groove 3224. Two positioning soft glues 3225 are also provided in the slide groove 3224. A positioning hole 3226 is provided in the middle of the connecting plate 321. Wave-shaped positioning notches 3227 are provided on the hole walls on both sides of the positioning hole 3226. The positioning notch 3227 is compatible with the positioning soft glue 3225, and the positioning soft glue 3225 conflicts with the positioning notch 3227. When the fixed shell 322 is subjected to external force, the external force is greater than the friction between the positioning soft glue 3225 and the positioning notch 3227, so the fixed shell 322 can slide relative to the connecting plate 321. When the fixed shell 322 slides to the appropriate position, the external force applied to the fixed shell 322 is less than the friction between the positioning soft glue 3225 and the positioning groove 3227. The positioning of the fixed shell 322 is achieved through the friction between the positioning soft glue 3225 and the positioning groove 3227, preventing the fixed shell 322 from sliding again.

[0057] There are many ways to fix the electronic device by the support mechanism 3, such as clamping the electronic device through a card slot, or clamping the electronic device with a clamping arm, etc. However, these fixing methods are limited by the size of the electronic device and can only fix one type of electronic device, such as only fixing a mobile phone or only fixing a tablet computer, and cannot simultaneously meet the needs of fixing different types of electronic devices.

[0058] In some embodiments, as Figure 8 As shown, the support mechanism 3 is provided with a magnet 33 inside, which is used to magnetically connect with the electronic device. By using magnetic attraction to fix the electronic device, it is not affected by the size of the electronic device itself, and can simultaneously meet the needs of fixing different types of electronic devices, which has a wider application.

[0059] In some embodiments, as Figure 8 As shown, multiple magnets 33 are arranged along the circumferential direction of the support mechanism 3, which has a better magnetic attraction effect.

[0060] It can be seen that the utility model discloses an electric adsorption bracket, including a base, an electric adsorption mechanism and a supporting mechanism. The electric adsorption mechanism also includes a suction cup, an air extraction component and an air supply component. The suction cup is provided with an air hole, and the air extraction component includes an air extraction pipe connected to the air hole. When the electric adsorption bracket needs to be fixed, a closed space is formed by covering the contact plane with the suction cup. After the air extraction component is actuated, the air in the closed space is extracted through the air hole and the air extraction pipe, so that the closed space is in a vacuum state, and the suction cup is adsorbed on the contact plane, and the fixing effect is better; when the electric adsorption bracket needs to be moved, air is supplied to the closed space through the air supply component, and the closed space in a vacuum state loses its adsorption force after air enters, and the suction cup is released from the contact plane. When it is fixed again, the air extraction component can be restarted, which is more convenient.
