For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0038] First, please refer to Figure 1 and Figure 2The utility model provides a suction cup bracket 10, which can be used to install and fix electronic devices such as mobile phones and tablets. The suction cup bracket 10 can be adsorbed on a supporting plane, such as a support platform inside a car. The mobile phone is fixed and the angle is adjusted by the suction cup bracket 10, so as to facilitate user use. The suction cup bracket 10 includes a magnetic suction component 100, a main body 200 and a suction cup 300. The magnetic suction component 100 is used to magnetically fix the mobile phone. The main body 200 is used to support the magnetic suction component 100. The main body 200 is rotatably connected to the magnetic suction component 100. The suction cup bracket 10 also includes a universal ball head 400. The universal ball head 400 is arranged between the main body 200 and the magnetic suction component 100 and is respectively connected to the main body 200 and the magnetic suction component 100. At least one of the main body 200 and the magnetic suction component 100 rotates relative to the universal ball head 400, so that The magnetic component 100 can rotate in any direction relative to the main body 200. The suction cup 300 is arranged on the side of the main body 200 facing away from the magnetic component 100. The suction cup 300 is attached to the external supporting plane to form a closed chamber 310, so that the suction cup 300 is automatically adsorbed on the external supporting plane. When the suction cup 300 is automatically adsorbed on the supporting plane and the mobile phone is magnetically fixed to the magnetic component 100, the magnetic component 100 is rotated relative to the main body 200 through the universal ball head 400, so that the mobile phone can adjust its angle in any direction, which is convenient for users to use.

[0039] refer to Figure 3 The magnetic attraction component 100 includes a magnet 110 and a support plate 120. The support plate 120 is provided with a receiving groove 124. The magnet 110 is received in the receiving groove 124. The magnet 110 can magnetically fix the mobile phone to the support plate 120. The support plate 120 is used to support the mobile phone. The other side of the support plate 120 is connected to the universal ball head 400. In this embodiment, the magnet 110 is an annular structure, and the receiving groove 124 is an annular groove connected end to end. The annular magnet 110 can ensure that when the mobile phone is placed on the support plate 120 at different angles, it can maintain sufficient magnetic attraction between the magnet 110 and the mobile phone.

[0040] The magnetic attraction component 100 also includes a cover plate 130, which covers the side of the support plate 120 facing away from the main body 200. The cover plate 130 can be covered by snap-fitting, threaded connection or adhesive connection, etc. After the cover plate 130 covers the support plate 120, the annular receiving groove 124 is closed to prevent the magnet 110 from detaching from the receiving groove 124. The surface of the cover plate 130 can be set to an anti-slip material to prevent the mobile phone from slipping.

[0041] In one embodiment, the universal ball head 400 includes a ball 410 and a connecting rod 420. The ball 410 is fixedly connected to the connecting rod 420. For example, the ball 410 and the connecting rod 420 are integrally cast. The connecting rod 420 is fixedly connected to the side of the support plate 120 facing away from the magnet 110. A rotating groove 210 is formed on the side of the main body 200 close to the magnetic attraction assembly 100. The rotating groove 210 is a spherical groove. The ball 410 is accommodated in the rotating groove 210 and can rotate in the rotating groove 210. It should be noted that when the ball 410 rotates in the rotating groove 210, it can be a damped rotation. Without external force, the ball 410 is stationary in the rotating groove 210 to prevent the mobile phone from swinging randomly after being installed on the support plate 120. It can be understood that the universal ball head 400 can also include a connecting rod 420 and two balls 410. The two balls 410 are respectively fixedly connected to opposite ends of the connecting rod 420. Both the main body 200 and the support plate 120 are provided with rotating grooves 210. The two balls 410 are respectively rotatably arranged in the two rotating grooves 210, so that both the main body 200 and the universal ball head 400 and the support plate 120 and the universal ball head 400 can rotate, thereby increasing the flexibility of the mobile phone use angle.

[0042] In this embodiment, the end of the connecting rod 420 facing away from the ball 410 is fixedly connected to the support plate 120. The support plate 120 is provided with a mounting hole 121 for accommodating the end of the connecting rod 420. The support plate 120 is also provided with a fixing block 123. The fixing block 123 is located on the side of the support plate 120 facing away from the connecting rod 420. The connecting rod 420 is snap-connected to the fixing block 123 through the mounting hole 121. Two opposite stoppers 122 are protrudingly arranged on the hole wall of the mounting hole 121. The stoppers 122 prevent the connecting rod 420 and the fixing block 123 from moving along the axial direction of the connecting rod 420. Two limiting blocks 421 are protrudingly arranged at the end of the connecting rod 420 close to the fixing block 123. When the end of the connecting rod 420 close to the fixing block 123 is accommodated in the mounting hole 121, the two limiting blocks 421 just snap into the space between the two stoppers 122, so as to limit the connecting rod 420 in the circumferential rotation direction around its axis. Thus, after the connecting rod 420 is snap-connected to the fixing block 123, the connecting rod 420 is limited both in the axial extension direction and in the circumferential rotation direction around the axis. It can be understood that the connection manner between the connecting rod 420 and the fixing block 123 can also be fixed by screw connection. It should be noted that the fixing block 123 can also not be provided. For example, a groove is provided on the hole wall of the mounting hole 121, and a flange is provided at the end of the connecting rod 420. The flange is embedded in the groove to fixedly connect the connecting rod 420 to the support plate 120. In addition, the fixing connection manner between the connecting rod 420 and the support plate 120 can also be other ways, such as screw connection, integral connection, etc.

[0043] Reference Figures 3 to 5The main body 200 is provided with an upper plate 220 and an annular fastener 230. The upper plate 220 is located on the side of the main body 200 close to the support plate 120. The upper plate 220 is recessed to form a first circular groove 221. The annular fastener 230 is enclosed to form a second circular groove 231. The radial distance of the first circular groove 221 gradually decreases in the process of approaching the suction cup 300 along the depth direction thereof, and the radial distance of the second circular groove 231 gradually increases in the process of approaching the suction cup 300 along the depth direction thereof. The annular fastener 230 is buckled with the upper plate 220, and the first circular groove 221 is aligned with the second circular groove 231. The rotating groove 210 is enclosed and formed, and the maximum radial distance of the first circular groove 221 and the maximum radial distance of the second circular groove 231 are both not less than the radial distance of the sphere 410. The sphere 410 is inserted into the first circular groove 221 and the second circular groove 231. The second circular groove 231 is open on one side close to the support plate 120. Part of the structure of the sphere 410 extends out through the opening structure and is connected to the connecting rod 420. The opening structure is used to avoid the connecting rod 420, and the maximum radial distance of the opening structure is less than the radial distance of the sphere 410 to prevent the sphere 410 from escaping from the rotating groove 210 at the opening structure.

[0044] The edge of the annular fastener 230 is provided with a barb 232, and the upper plate 220 is provided with a fixing hole 222 at the edge of the first circular groove 221. The barb 232 passes through the fixing hole 222 so that the annular fastener 230 is buckled and connected with the upper plate 220. In the depth direction of the second circular groove 231 and the fixing hole 222, the end of the barb 232 is provided with a relative inclined surface 2321 and a clamping surface 2322. The inclined surface 2321 is inclined to the depth direction of the fixing hole 222, and the clamping surface 2322 is perpendicular to the depth direction of the fixing hole 222. When the annular fastener 230 is buckled with the upper plate 220, under the push of external force, the barb 232 abuts against the upper plate 220, and the outer opening edge of the fixing hole 222 slides relatively along the inclined surface 2321. At the same time, the fixing hole The outer opening edge of 222 squeezes the inclined surface 2321 to cause the hook 232 to deform and shrink toward the center direction of the annular fastener 230, and the annular fastener 230 continues to be pushed. The inclined surface 2321 slides through the fixing hole 222, and the hook 232 resumes its deformation. At this time, the clamping surface 2322 abuts against the edge of the inner opening of the fixing hole 222, so that the annular fastener 230 is upper-limited along the depth direction of the fixing hole 222, and the annular fastener 230 is buckled and engaged with the upper plate 220. It can be understood that when the sphere 410 is installed to the main body 200, the sphere 410 is first installed to the second circular groove 231, and then the hook 232 is passed through the fixing hole 222 to buckle the annular fastener 230 with the upper plate 220, so that the sphere 410 is limited in the rotating groove 210.

[0045] A plurality of barbs 232 are provided, and the number and positions of the fixing holes 222 correspond to those of the barbs 232. In this embodiment, four barbs 232 are provided, and the four barbs 232 are spaced apart and circumferentially arranged on one side edge of the annular fastener 230 close to the upper plate 220. Four fixing holes 222 are provided, and the four fixing holes 222 are spaced apart and circumferentially arranged around the first circular groove 221. The four barbs 232 respectively pass through the corresponding fixing holes 222, so that the annular fastener 230 is more tightly fastened to the upper plate 220. It can be understood that the number of barbs 232 and fixing holes 222 is not limited. In order to make the annular fastener 230 more stable when fastened to the upper plate 220, the number of barbs 232 and fixing holes 222 is more than two.

[0046] In one embodiment, referring to Figure 6 , after the suction cup 300 fits with the external support plane, it automatically adsorbs to the external support plane. Specifically, the suction cup bracket 10 further includes a control component 500. The main body 200 is provided with an installation cavity 240, and the control component 500 is fixed in the installation cavity 240. The control component 500 can make the suction cup 300 automatically adsorb to the external support plane and continuously monitor the adsorption pressure, so that when the suction cup bracket 10 is in use, the adsorption operation of the suction cup 300 is more convenient, the adsorption effect is stronger, and the suction cup bracket 10 will not accidentally fall off during use.

[0047] Referring to Figure 7 and Figure 8 , the control component 500 includes a main board 510, a motor 520 and an exhaust component 530. The main board 510 is fixed in the installation cavity 240, and the motor 520 is electrically connected to the main board 510. The main board 510 issues an electrical signal to control the start or stop of the motor 520. A pressure detection element 511 is provided on the main board 510. The pressure detection element 511 is communicated with the closed chamber 310 and can detect the real-time air pressure value of the closed chamber 310. When the pressure detection element 511 detects that the pressure value of the closed chamber 310 is higher than the preset value of the pressure detection element 511, the pressure detection element 511 issues an electrical signal and transmits it to the motor 520 through the main board 510 to control the motor 520 to start. The motor 520 drives the exhaust component 530 to exhaust the closed chamber 310. The exhaust component 530 includes a piston 531 and a cylinder 532. The motor 520 drives the piston 531 to pull air in the cylinder 532. The cylinder 532 is communicated with the closed chamber 310 to reduce the air pressure value of the closed chamber 310. The external atmospheric pressure presses the suction cup 300 against the external support plane, so that the suction cup 300 adsorbs to the external support plane. When the air pressure in the closed chamber 310 is less than the preset value of the pressure detection element 511, the suction cup 300 tightly adsorbs to the external support plane, and the pressure detection element 511 issues an electrical signal here and transmits it to the motor 520 to control the motor 520 to turn off. It can be understood that the pressure preset value of the pressure detection element 511 is not greater than the pressure value of the external atmospheric pressure.

[0048] It should be noted that the working principle of the air pressure detection element 511 is usually that the medium pressure directly acts on the diaphragm of the sensor, causing the diaphragm to generate a micro-displacement proportional to the medium pressure. This micro-displacement will change the internal resistance of the sensor, and then through the electronic circuit, this displacement is converted into a standard signal corresponding to the pressure. The air pressure detection element 511 is particularly suitable for measuring the pressure value when the measured pressure is greater than the predetermined pressure value. During the inhalation stage, observe whether the signal output by the air pressure detection element 511 rapidly drops to within the preset negative pressure value range and remains stable, which can determine whether the suction cup 300 has successfully adsorbed on the support plane. After maintaining the adsorption state for a period of time, observe again whether the output signal of the air pressure detection element 511 changes. If the signal suddenly rises, it indicates that there may be a leak in the closed space of the suction cup 300. If a leak is detected, the severity of the leak can be judged based on the degree and speed of the leak, and corresponding measures can be taken to repair or replace the suction cup 300. The above working principle of the air pressure detection element 511 is not limited here, as long as it can meet the requirement of detecting the air pressure in the closed chamber 310 by the air pressure detection element 511 and form an electrical signal to enable the motor 520 to control the exhaust part 530 to exhaust.

[0049] The motor 520 drives the piston 531 to pull in the cylinder 532, so as to discharge the gas in the cylinder 532. A dial rod 521 is fixedly arranged at one end edge of the motor 520. When the motor 520 starts, the dial rod 521 is driven to rotate circumferentially around the central axis of the motor 520. A driving hole 5311 is arranged at one end of the piston 531 close to the motor 520, and the driving hole 5311 extends along a direction perpendicular to the pulling direction of the piston 531. The dial rod 521 passes through the driving hole 5311, so that the dial rod 521 is limited relative to the piston 531 along a direction perpendicular to the pulling direction of the piston 531. When the motor 520 starts, the motor 520 drives the dial rod 521 to rotate circumferentially along a circular track. While the dial rod 521 rotates circumferentially, it pulls the piston 531 to move in the cylinder 532, and the dial rod 521 moves in the driving hole 5311 along a direction perpendicular to the pulling direction. That is, the circumferential rotation of the dial rod 521 can be decomposed into a movement along the pulling direction of the piston 531 and a movement along a direction perpendicular to the pulling direction of the piston 531, so that the dial rod 521 drives the piston 531 to move along the pulling direction and moves in the driving hole 5311 along a direction perpendicular to the pulling direction.

[0050] The control component 500 further includes a deflation button 540. The deflation button 540 is used to allow external gas to enter the enclosed space so that the suction cup 300 detaches from the support plane. The cylinder 532 includes a pulling cylinder 5321 and a buffer cylinder 5322. The pulling cylinder 5321 and the buffer cylinder 5322 are communicated through a hole-like structure. The movement of the piston 531 in the pulling cylinder 5321, the other side of the buffer cylinder 5322 is communicated with the enclosed chamber 310. The gas in the enclosed chamber 310 passes through the buffer cylinder 5322 to the pulling cylinder 5321, pulling the piston 531, and the gas in the enclosed chamber 310 is discharged. The deflation button 540 includes a bolt 541 and an elastic member 542. One end of the bolt 541 passes through the wall of the installation cavity 240 for the user to press. The buffer cylinder 5322 is provided with a deflation hole 5323 for the other end of the bolt 541 to pass through. The elastic member 542 abuts against the inner wall of the bolt 541 and the buffer cylinder 5322 respectively. The elastic member 542 pushes the bolt 541 to close the deflation hole 5323 so that the inside of the buffer cylinder 5322 remains in a sealed state. The end of the bolt 541 is provided with a flange structure matching the deflation hole 5323. A leather ring 543 is sleeved on the flange structure. When the elastic member 542 pushes the end of the bolt 541 to block the deflation hole 5323, the leather ring 543 fills the gap between the bolt 541 and the inner wall of the deflation hole 5323. When it is necessary to detach the suction cup 300 from the support plane, press the bolt 541, the deflation hole 5323 is opened, the leather ring 543 detaches from the deflation hole 5323, and the external gas enters the buffer cylinder 5322 through the deflation hole 5323 and enters the enclosed chamber 310 through the buffer cylinder 5322, so that the air pressure in the enclosed chamber 310 is balanced with the external air pressure, and the suction cup 300 detaches from the external support plane.

[0051] The pulling cylinder 5321 is provided with a first one-way air valve 5324 and a second one-way air valve 5325. The first one-way air valve 5324 is used to connect the inside of the pulling cylinder 5321 cavity and the external gas. The second one-way air valve 5325 is used to connect the inside of the pulling cylinder 5321 cavity and the inside of the buffer cylinder 5322 cavity. The gas in the pulling cylinder 5321 is discharged to the outside through the first one-way air valve 5324. The first one-way air valve 5324 allows the gas to flow from the inside of the pulling cylinder 5321 to the outside, and at the same time blocks the external gas from entering the inside of the pulling cylinder 5321. The second one-way air valve 5325 allows the gas to enter the pulling cylinder 5321 from the buffer cylinder 5322, and at the same time blocks the gas in the pulling cylinder 5321 from entering the buffer cylinder 5322. Thus, when the piston 531 is pulled in the pulling cylinder 5321, the gas only enters the pulling cylinder 5321 from the buffer cylinder 5322 through the second one-way air valve 5325. When the piston 531 is pushed in the reverse direction, the gas is discharged from the pulling cylinder 5321 to the outside through the first one-way air valve 5324, so as to ensure that the pulling cylinder 5321 can extract the gas in the enclosed chamber 310 without pushing the gas into the enclosed chamber 310. It should be noted that the structure of the one-way air valve is prior art and will not be explained in detail here.

[0052] Continue to refer to Figure 7 and Figure 8 The control component 500 further includes a vent pipe 550 for ventilation. The vent pipe 550 includes a first pipe body 551, a second pipe body 552, and a third pipe body 553 that are interconnected. One end of the first pipe body 551 is connected to the air pressure detection element 511, and the other end is respectively connected to the second pipe body 552 and the third pipe body 553. One end of the second pipe body 552 is connected to the sealed chamber 310, and the other end is respectively connected to the first pipe body 551 and the third pipe body 553. One end of the third pipe body 553 is connected to the buffer cylinder 5322, and the other end is respectively connected to the first pipe body 551 and the second pipe body 552. The air pressure detection element 511 simultaneously detects the pressure value of the sealed chamber 310 and the pressure value of the buffer cylinder 5322, and the pressure values of the sealed chamber 310 and the buffer cylinder 5322 are the same in real time, so that the air pressure detection element 511 can detect the air pressure in real time during the pulling process of the piston 531.

[0053] The main board 510 is also provided with a detection switch 512 that controls the opening or closing of the air pressure detection element 511. When the suction cup bracket 10 is not in use, the detection switch 512 controls the air pressure detection element 511 to close to prevent the air pressure detection element 511 from misdetection and to control the motor 520 to continue working. The pull bolt 541 includes a first section 5411 and a second section 5412 that are connected to each other. The first section 5411 passes through the air vent hole 5323, and the second section 5412 is for the user to press. In this embodiment, the second section 5412 is connected to the first section 5411 through a connection structure, and the second section 5412 and the first section 5411 are not on the same straight line. The detection switch 512 is located on the pressing movement path of the second section 5412. When the second section 5412 is pressed, the second section 5412 triggers the detection switch 512, and the detection switch 512 controls the air pressure detection element 511 to close. At the same time, the first section 5411 opens the air vent hole 5323, and the gas enters the sealed chamber 310 through the buffer chamber, so that the suction cup 300 is separated from the external support plane. When the suction cup bracket 10 is in use, when the second section 5412 is pressed again, the detection switch 512 controls the air pressure detection element 511 to open. After the external force is removed, the air vent hole 5323 is closed by the first section 5411. At this time, the air pressure detection element 511 starts to operate and detects the pressure of the sealed chamber 310 to control the operation of the motor 520.

[0054] In the second embodiment, refer to Figure 9 and Figure 10, the difference between this embodiment and the above embodiment is that two spaced chutes 250 are fixedly provided on the outer side surface of the main body 200. One end of the bolt 541 for the user to press is located within the space between the two chutes 250. The main body 200 further includes an anti-touch plate 260. The end of the anti-touch plate 260 is slidably disposed in the chute 250. The anti-touch plate 260 covers the bolt 541 to prevent the sucker bracket 10 from falling off due to accidental touch of the bolt 541. A return spring 251 is disposed in the chute 250. The return spring 251 pushes the anti-touch plate 260 to the position of the bolt 541 and always covers the bolt 541. When it is necessary to press the bolt 541, the anti-touch plate 260 is pushed. The anti-touch plate 260 slides along the chute 250 to expose the bolt 541. The return spring 251 deforms and stores an elastic force opposite to the sliding direction of the anti-touch plate 260. When the external thrust is removed, under the push of the return spring 251, the anti-touch plate 260 slides in the opposite direction along the chute 250 to re-cover the bolt 541 and return to the initial state.

[0055] The anti-touch plate 260 includes a movable plate 261 and a baffle plate 262. There are two movable plates 261 which are respectively disposed in the two chutes 250. The movable plate 261 slides in the chute 250. Two ends of the baffle plate 262 are fixedly connected to the movable plate 261 respectively. The baffle plate 262 covers the bolt 541. When the movable plate 261 slides, it drives the baffle plate 262 to move simultaneously.

[0056] A sliding shaft 252 is further disposed in the chute 250. The return spring 251 is sleeved on the sliding shaft 252. The sliding shaft 252 extends along the sliding direction of the movable plate 261. The sliding shaft 252 penetrates through the movable plate 261 so that the movable plate 261 moves along the sliding shaft 252 when sliding, preventing the movable plate 261 from shifting and loosening. One end of the return spring 251 abuts against the inner wall of the chute 250, and the other end abuts against the movable plate 261, thereby driving the baffle plate 262 to always cover the bolt 541.
