Description

Technical Field

[0001] The invention belongs to the field of wireless mobile power supplies, in particular to a wireless charging mobile power supply for mobile phones. Background Art

[0002] Wireless charging is mainly achieved through the following three methods: electromagnetic induction, radio waves, and electromagnetic resonance. The most common wireless charging solution is electromagnetic induction, which generates current through the primary and secondary coils, thereby transferring energy from the transmission section to the receiving end. However, when charging a mobile phone, the wireless mobile power supply needs to be placed horizontally, and then the mobile phone is placed horizontally on the wireless mobile power supply. When the user needs to use the mobile phone to watch movies or browse the web, the user needs to look directly at the mobile phone screen, which is inconvenient for the user to use. In addition, when walking, it is inconvenient for the user to carry the wireless mobile power supply that is charging the mobile phone, and the mobile phone is easy to fall from the wireless mobile power supply, causing damage to the mobile phone or the wireless mobile power supply.

[0003] Some technical solutions of wireless mobile power devices have also appeared in the prior art. For example, a Chinese patent with application number CN201510768199.7 discloses a portable wireless mobile power, which mainly includes: a rectangular shell, two longer sides of the shell are provided with mutually parallel slide grooves, a suction cup is provided on the upper surface of the shell, and a slide cover is connected to the slide groove, and the slide cover is arranged on the upper part of the suction cup on the upper surface of the shell. Although the suction cup arranged on the outer surface of the portable wireless mobile power can allow the wireless mobile power to be adsorbed on the back of the mobile phone when the user is charging the mobile phone, so that the user can operate the mobile phone very conveniently, when the suction cup arranged on the outer surface of the wireless mobile power of the device is not completely adsorbed, the suction force generated by the suction cup cannot ensure whether the mobile phone can be adsorbed on the wireless mobile power, so that the user still needs to pay attention to whether the mobile phone falls, which affects the user's mood. In addition, when the suction cup completely fixes the mobile phone, when the mobile phone needs to be taken off, the suction cup has a certain adsorption effect on the mobile phone, which makes it inconvenient for the mobile phone to be taken off and inconvenient for the user to use. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention solves the problem that when a wireless mobile power supply is used to charge a mobile phone, the wireless mobile power supply needs to be placed horizontally, and then the mobile phone needs to be placed horizontally on the wireless mobile power supply. When the user needs to use the mobile phone to watch a movie or browse the web, the user needs to look directly at the mobile phone screen, which is inconvenient for the user to use. In addition, when walking, it is inconvenient for the user to carry the wireless mobile power supply that is charging the mobile phone, and the mobile phone is easily dropped from the wireless mobile power supply, causing damage to the mobile phone or the wireless mobile power supply. A wireless charging mobile phone power supply is proposed in the present invention.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a wireless charging mobile power supply described in the present invention includes a shell; a first slide groove is provided on the shell; there are a plurality of the first slide grooves, which are symmetrically distributed along the center line in the length direction of the shell; the cross section of the first slide groove is T-shaped, and the upper part of the first slide groove passes through the upper surface of the shell; a bracket is elastically connected to the first slide groove through a first spring; the bracket includes a slider, a rotating rod and a clamping rod; one end of the first spring is fixedly connected to the inner wall of the first slide groove on one side of the center line in the length direction of the middle of the shell, and the other end is fixedly connected to the side wall below the slider; the lower part of the rotating rod Hinged with the top of the slider; a second slide groove is provided on the upper surface of the rotating rod; the lower end of the clamping rod is slidably connected to the inside of the second slide groove through a second spring; the cross section of the top of the clamping rod is L-shaped; a groove is provided on the top of the shell; the cross section of the groove is L-shaped; the groove is connected to the top of the first slide groove at one end in the horizontal direction, and the depth of the groove in the vertical direction is greater than the depth of the groove in the horizontal direction; the shapes of the groove and the clamping rod match each other; a first circular groove is provided inside the shell, and the center of the first circular groove coincides with the center point of the shell; a coil is fixedly connected in the first circular groove; the coil is electrically connected to the power supply inside the shell;

[0006] When working, in the initial state, because the lower end of the rotating rod is hinged with the upper end of the slider, one end of the clamping rod in the horizontal direction extends into the inner part of the groove in the vertical direction, and the first spring is in a stretched state, so that the rotating rod and the clamping rod are locked under the action of the first spring; the surface of the rotating rod and the clamping rod on the side away from the first spring is in a parallel state with the upper surface of the housing;

[0007] When the user uses the wireless mobile power bank to charge the mobile phone, the user first moves the clamping rod so that the clamping rod drives the rotating rod to be in a vertical state, and releases the lock of the rotating rod and the clamping rod. At this time, because the elastic force of the first spring is greater than the friction between the slider and the bottom of the first slide groove, the first spring drives the bracket to move away from the groove. After the bracket stops moving, the bracket is moved. Because the force exerted by the user on the bracket is greater than the pulling force of the first spring on the bracket and the friction between the bottom of the bracket and the first slide groove, the bracket moves in a direction away from the first spring. At this time, the mobile phone is placed in the bracket. The clamping space is formed, and then the clamping rod is pulled upward. Since the force of the clamping rod on the clamping rod by human power is greater than the pulling force of the second spring on the clamping rod, the friction between the clamping rod and the side wall of the second slide groove, and the gravity of the clamping rod, the clamping rod moves upward inside the second slide groove. When the clamping rod moves to the top of the mobile phone on the lower surface of the horizontal part, the clamping rod is released. Since the pulling force of the second spring on the clamping rod is greater than the friction between the clamping rod and the inner wall of the second slide groove, the clamping rod is closely contacted with the surface of the mobile phone on the lower surface in the horizontal direction. Then, the bracket and the clamping rod are pulled in turn, so that each The clamping rod at the position is in close contact with the surface of the mobile phone on the lower surface of the horizontal part, so that the mobile phone is fixed on the outer surface of the wireless mobile power supply, ensuring that the mobile phone does not need to be placed on a plane or manually held when charging, which is convenient for the user to continue to use the mobile phone when the mobile phone is charging, effectively improving the practicality of the wireless mobile power supply, and preventing the mobile phone from falling from the surface of the wireless mobile power supply. In addition, the first slide groove is elastically connected with a bracket through the first spring, so that the bracket can slide inside the first slide groove, so that the bracket can clamp mobile phones of different sizes, effectively improving the practicality of the wireless mobile power supply; after the mobile phone is charged, the clamping rod is first stretched upward, and then the bracket is moved away from the first spring to move to the side, and the mobile phone is taken out. At this time, the first spring drives the bracket to reset; then, the bracket is moved to move away from the first spring. At this time, the clamping rod is toggled, so that the clamping rod drives the rotating rod to move toward the inner direction of the groove, so that the clamping rod at one end in the horizontal direction enters the inner part of the groove in the vertical direction, so that the wireless mobile power supply is restored to the initial state, effectively preventing the bracket from extending out of the groove, affecting the beauty of the wireless mobile power supply, and causing the wireless mobile power supply to be inconvenient to carry.

[0008] Preferably, the rotating rod and the clamping rod are evenly fixed with a plurality of rubber blocks on the surface of one side close to the first spring; the clamping rod is evenly fixed with a plurality of rubber blocks on the lower surface in the horizontal direction;

[0009] During operation, after the mobile phone is clamped by the bracket, the multiple rubber blocks uniformly connected to the rotating rod and the clamping rod on the surface of one side close to the first spring can increase the friction between the side wall of the mobile phone and the rotating rod and the clamping rod, effectively preventing the mobile phone from sliding and falling. The multiple rubber blocks uniformly connected to the lower surface of the horizontal part of the clamping rod can increase the friction between the use surface of the mobile phone and the clamping rod, and prevent the clamping rod from directly contacting the use surface of the mobile phone on the lower surface in the horizontal direction, thereby effectively preventing the clamping rod from scraping the use surface of the mobile phone, so that while increasing the friction between the mobile phone and the bracket, the mobile phone screen is effectively protected from wear.

[0010] Preferably, the first slide groove has multiple rubber strips evenly fixed to the side walls on both sides in the vertical direction; the rubber strips are all inclined toward the groove;

[0011] During operation, since the rubber strips on the side walls of the first slide groove are inclined toward the groove and the rubber strips are in contact with the side walls of the slider, and the pulling force of the first spring on the bracket is greater than the friction between the bottom of the bracket and the inner wall of the first slide groove and the friction between the side walls of the slider and the rubber strip, the first spring pulls the bracket to reset, and since friction is generated between the side walls of the slider and the rubber strip, the first spring is effectively prevented from pulling the bracket to reset quickly, thereby preventing the bracket from hitting a person's hand, effectively improving the safety protection performance of the wireless mobile power supply, and preventing the bracket from being worn and affecting the normal use of the wireless mobile power supply.

[0012] Preferably, a plurality of second circular grooves are evenly provided on the top of the shell; the second circular grooves pass through the upper surface of the shell above; the second circular grooves are evenly distributed around the center line of the first circular groove, and the second circular grooves and the first circular grooves do not contact each other; a third spring is fixedly connected to the center of the bottom of the second circular groove; the upper end of the third spring is fixedly connected to the lower surface of the telescopic tube; a suction cup is fixedly connected to the upper end of the telescopic tube; the circumferential surface of the suction cup in the second circular groove is fixedly connected to the inner wall of the second circular groove; the suction cup is connected to the telescopic tube by a design of communication; the suction cup is fixedly connected to the upper surface of the shell at the part extending out of the circumference of the shell; the shell is provided with a plurality of third slide grooves on the circumference of the second circular groove; the cross section of the third slide groove is L-shaped; the upper part of the third slide groove passes through the upper surface of the shell, and the upper part of the third slide groove is located in the space formed by the fixed connection of the circumference of the suction cup and the upper surface of the shell; a sliding rod is slidably connected in the third slide groove; the sliding rod extends out of the third slide groove in the vertical direction, and the sliding rod does not contact the suction cup; the sliding rod is fixedly connected to the lower side wall of the telescopic tube at one end of the horizontal part;

[0013] When working, in the initial state, because the elastic force of the third spring is greater than the gravity of the telescopic tube, the gravity of the suction cup and the friction between the slide bar and the third slide groove, the upper surface of the slide bar on the horizontal part contacts the upper surface of the third slide groove on the horizontal part;

[0014] When the mobile phone is clamped by the bracket, first, the back of the mobile phone contacts the suction cup, and a closed space is formed between the back of the mobile phone and the suction cup and the telescopic tube. When the mobile phone is pressed down by the clamping rod, the mobile phone squeezes the suction cup, and the suction cup squeezes the sliding rod. Because the pulling force of the second spring on the clamping rod and the gravity of the mobile phone are greater than the supporting force of the third spring on the telescopic tube and the friction between the sliding rod and the inner wall of the third slide groove, the sliding rod moves downward in the third slide groove. When the lower surface of the sliding rod contacts the lower surface of the third slide groove on the horizontal part, the upper end of the sliding rod completely enters the third slide groove. Because the sliding rod drives the telescopic tube to move downward in the second circular groove, the internal space of the suction cup and the telescopic tube increases, and a closed space is formed between the telescopic tube, the suction cup and the back of the mobile phone. At this time, due to the increase in the space formed inside the suction cup and the telescopic tube, the internal air pressure of the closed space formed between the telescopic tube, the suction cup and the back of the mobile phone is reduced, forming a negative pressure, so that the suction cup can tightly adsorb the back of the mobile phone, thereby preventing the mobile phone from falling, and strengthening the surface connectivity between the mobile phone and the wireless mobile power bank.

[0015] Preferably, a fourth slide groove is provided below the first slide groove on the side wall close to the second circular groove, and the length direction of the fourth slide groove is parallel to the length direction of the first slide groove; the fourth slide groove is located at the end away from the first spring, and the fourth slide groove is connected to the first slide groove; an air cavity is provided inside the shell; one end of the air cavity is connected to the fourth slide groove, and the other end is connected to the second circular groove; the air cavity is connected to the inside of the telescopic tube through a conduit; the fourth slide groove is elastically connected to a pressure plate on the side wall away from the first spring through a plurality of fourth springs that are evenly fixed; the pressure plate is fixed with a rubber plug on the surface of the side close to the air cavity; one end of the pressure plate extends into the first slide groove;

[0016] When working, in the initial state, the elastic force of the fourth spring on the pressure plate and the friction between the rubber plug and the inner wall of the fourth slide groove are greater than the thrust of the rubber plug by the air pressure generated by the suction cup and the internal space of the telescopic tube after the mobile phone presses down the suction cup, so that the rubber plug is closely attached to the connection between the fourth slide groove and the air cavity, so that the air cavity and the fourth slide groove are mutually sealed;

[0017] When the mobile phone needs to be removed, the bracket is pushed to move in a direction away from the first spring. Since the force exerted by human power on the bracket is greater than the pulling force of the first spring on the bracket, the friction between the bottom of the bracket and the inner wall of the first slide groove, the friction between the side walls of the slider and the rubber strip, the elastic force of the fourth spring on the pressure plate, the friction between the rubber plug and the inner wall of the air cavity, and the friction between the pressure plate and the inner wall of the fourth slide groove, the bracket pushes the pressure plate to move in a direction away from the first spring, and the pressure plate drives the rubber plug to move in a direction away from the air cavity, so that the air cavity and the fourth slide groove are connected to each other, so that the gas passes through the air cavity through the conduit into the enclosed space formed between the suction cup and the telescopic tube and the back of the mobile phone, thereby forming a space between the suction cup and the telescopic tube and the back of the mobile phone. The air pressure inside the enclosed space increases, so that the suction cup is separated from the back of the mobile phone, and the mobile phone is taken off smoothly, avoiding the suction cup sucking the mobile phone after the mobile phone is charged, making it difficult to take off the mobile phone, and easily damaging the suction cup when the mobile phone is forcibly pulled off; after the mobile phone is taken off, the bracket is loosened, so that the first spring pulls the bracket to move in the direction of the first spring. At this time, because the elastic force of the fourth spring is greater than the friction between the pressure plate and the inner wall of the fourth slide groove, and the friction between the rubber plug and the inside of the air cavity, the fourth spring pushes the pressure plate, and the pressure plate drives the rubber plug to move in the direction of the first spring, so that the rubber plug is smoothly inserted into the air cavity, so that the next time the wireless mobile power supply charges the mobile phone, the suction cup can tightly adsorb the back of the mobile phone, effectively improving the prevention of the mobile phone from falling.

[0018] Preferably, the housing is made of thermally conductive plastic;

[0019] The shell is made of PP material after mold casting and has good thermal conductivity, so that the heat generated by the mobile phone during operation can be quickly transferred to the shell to dissipate the heat and avoid heat accumulation, which will cause the temperature of the mobile phone and the wireless mobile power bank to be too high and cause safety hazards. At the same time, it can effectively cool the mobile phone and the wireless mobile power bank, extend their service life and reduce their use costs.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The wireless charging mobile power bank described in the present invention can increase the friction between the mobile phone use surface and the clamping rod by arranging the rubber block, and prevent the clamping rod from directly contacting the mobile phone use surface in the horizontal direction, thereby effectively preventing the clamping rod from scraping the mobile phone use surface, so that while increasing the friction between the mobile phone and the bracket, the mobile phone screen is effectively protected from being worn and the mobile phone is prevented from sliding.

[0022] 2. The wireless charging mobile phone power bank described in the present invention can form a negative pressure when the internal air pressure of the enclosed space formed between the telescopic tube, the suction cup and the back of the mobile phone is reduced by arranging the suction cup, the telescopic tube and the sliding rod, so that the suction cup can tightly adhere to the back of the mobile phone, thereby preventing the mobile phone from falling and strengthening the surface connectivity between the mobile phone and the wireless mobile power bank.

[0023] 3. The wireless charging mobile power bank described in the present invention can realize that the pressure plate drives the rubber plug to move in the direction of the first spring by setting the air cavity, the pressure plate, the rubber plug and the fourth spring, so that the rubber plug can be smoothly inserted into the air cavity, so that the next time the wireless mobile power bank charges the mobile phone, the suction cup can tightly adhere to the back of the mobile phone, effectively preventing the mobile phone from falling.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 3As shown, a wireless charging mobile phone power bank described in the present invention comprises a shell 1; a first slide groove 2 is provided on the shell 1; there are a plurality of the first slide grooves 2, which are symmetrically distributed along the center line in the length direction of the shell 1; the cross section of the first slide groove 2 is T-shaped, and the upper part of the first slide groove 2 passes through the upper surface of the shell 1; a bracket 4 is elastically connected to the first slide groove 2 through a first spring 3; the bracket 4 comprises a slider 41, a rotating rod 42 and a clamping rod 43; one end of the first spring 3 is fixedly connected to the inner wall of the first slide groove 2 on one side close to the center line in the length direction of the middle part of the shell 1, and the other end is fixedly connected to the side wall below the slider 41; the lower part of the rotating rod 42 is hinged to the upper part of the slider 41; A second slide groove 5 is provided on the upper surface of the rotating rod 42; the lower end of the clamping rod 43 is slidably connected to the inside of the second slide groove 5 through a second spring 6; the cross section of the top of the clamping rod 43 is L-shaped; a groove 7 is provided on the top of the shell 1; the cross section of the groove 7 is L-shaped; the groove 7 is connected to the top of the first slide groove 2 at one end in the horizontal direction, and the depth of the groove 7 in the vertical direction is greater than the depth of the groove 7 in the horizontal direction; the shapes of the groove 7 and the clamping rod 43 match each other; a first circular groove 8 is provided inside the shell 1, and the center of the first circular groove 8 coincides with the center point of the shell 1; a coil 9 is fixedly connected in the first circular groove 8; the coil 9 is electrically connected to the power supply inside the shell 1;

[0031] During operation, in the initial state, since the lower end of the rotating rod 42 is hinged with the upper end of the slider 41, one end of the clamping rod 43 in the horizontal direction extends into the inner part of the groove 7 in the vertical direction, and the first spring 3 is in a stretched state, so that the rotating rod 42 and the clamping rod 43 are locked under the action of the first spring 3; the rotating rod 42 and the clamping rod 43 are parallel to the upper surface of the housing 1 on the side away from the first spring 3;

[0032] When the user uses the wireless mobile power bank to charge the mobile phone, the user first moves the clamping rod 43 so that the clamping rod 43 drives the rotating rod 42 to be in a vertical state, and releases the lock of the rotating rod 42 and the clamping rod 43. At this time, because the elastic force of the first spring 3 is greater than the friction between the slider 41 and the bottom of the first slide groove 2, the first spring 3 drives the bracket 4 to move away from the groove 7. After the bracket 4 stops moving, the bracket 4 is moved. Because the force exerted by the user on the bracket 4 is greater than the pulling force of the first spring 3 on the bracket 4 and the friction between the bottom of the bracket 4 and the first slide groove 2, the bracket 4 moves in the direction away from the first spring 3. At this time, put the mobile phone in The clamping rod 43 is inserted into the clamping space formed by the bracket 4, and then the clamping rod 43 is pulled upward. Since the force of the clamping rod 43 on the clamping rod 43 by the human power is greater than the pulling force of the second spring 6 on the clamping rod 43, the friction between the clamping rod 43 and the side wall of the second slide groove 5, and the gravity of the clamping rod 43, the clamping rod 43 moves upward inside the second slide groove 5. When the clamping rod 43 moves to the top of the mobile phone on the lower surface of the horizontal part, the clamping rod 43 is released. Since the pulling force of the second spring 6 on the clamping rod 43 is greater than the friction between the clamping rod 43 and the inner wall of the second slide groove 5, the clamping rod 43 is in close contact with the surface of the mobile phone on the lower surface in the horizontal direction. Then, the clamping rod 43 is pulled in sequence. The bracket 4 and the clamping rod 43 make the lower surface of the horizontal part of the clamping rod 43 at each position closely contact the surface of the mobile phone, so as to fix the mobile phone on the outer surface of the wireless mobile power supply, ensure that the mobile phone does not need to be placed on a flat surface or manually held when charging, and facilitate the user to continue to use the mobile phone while charging, effectively improving the practicality of the wireless mobile power supply, and preventing the mobile phone from falling from the surface of the wireless mobile power supply. The first slide groove 2 is elastically connected with the bracket 4 through the first spring 3, so that the bracket 4 can slide inside the first slide groove 2, so that the bracket 4 can clamp mobile phones of different sizes, effectively improving the practicality of the wireless mobile power supply; After charging the mobile phone, first stretch the clamping rod 43 upward, then bend the bracket 4 to move away from the first spring 3 to take out the mobile phone. At this time, the first spring 3 drives the bracket 4 to reset. Then, bend the bracket 4 to move away from the first spring 3. At this time, move the clamping rod 43 so that the clamping rod 43 drives the rotating rod 42 to move toward the inside of the groove 7, so that one end of the clamping rod 43 in the horizontal direction enters the inside of the groove 7 in the vertical direction, thereby restoring the wireless mobile power supply to its initial state, effectively preventing the bracket 4 from extending out of the groove 7, affecting the appearance of the wireless mobile power supply, and making the wireless mobile power supply inconvenient to carry.

[0033] As an embodiment of the present invention, the rotating rod 42 and the clamping rod 43 are evenly fixed with a plurality of rubber blocks 11 on the surface of one side close to the first spring 3; the clamping rod 43 is evenly fixed with a plurality of rubber blocks 11 on the lower surface in the horizontal direction;

[0034] During operation, after the mobile phone is clamped by the bracket 4, the multiple rubber blocks 11 uniformly connected to the rotating rod 42 and the clamping rod 43 on the surface of one side close to the first spring 3 can increase the friction between the side wall of the mobile phone and the rotating rod 42 and the clamping rod 43, effectively preventing the mobile phone from sliding and falling. The multiple rubber blocks 11 uniformly connected to the lower surface of the horizontal part of the clamping rod 43 can increase the friction between the mobile phone's use surface and the clamping rod 43, and prevent the clamping rod 43 from directly contacting the mobile phone's use surface on the lower surface in the horizontal direction, thereby effectively preventing the clamping rod 43 from scraping the mobile phone's use surface, so that while increasing the friction between the mobile phone and the bracket 4, the mobile phone screen is effectively protected from wear.

[0035] As an embodiment of the present invention, the first chute 2 has multiple rubber strips 12 evenly fixed to the side walls on both sides in the vertical direction; the rubber strips 12 are all inclined toward the groove 7;

[0036] During operation, since the rubber strips 12 on the side walls of the first slide groove 2 are inclined toward the groove 7 and the rubber strips 12 are in contact with the side walls of the slider 41, and the pulling force of the first spring 3 on the bracket 4 is greater than the friction between the bottom of the bracket 4 and the inner wall of the first slide groove 2 and the friction between the side walls of the slider 41 and the rubber strips 12, the first spring 3 pulls the bracket 4 to reset, and since the friction is generated between the side walls of the slider 41 and the rubber strips 12, the first spring 3 is effectively prevented from pulling the bracket 4 to reset quickly, thereby preventing the bracket 4 from hitting a person's hand, effectively improving the safety protection performance of the wireless mobile power supply, and preventing the bracket 4 from being worn and affecting the normal use of the wireless mobile power supply.

[0037] As an embodiment of the present invention, a plurality of second circular grooves 13 are evenly arranged on the top of the shell 1; the top of the second circular grooves 13 penetrates the upper surface of the shell 1; the second circular grooves 13 are evenly distributed around the center line of the first circular groove 8, and the second circular grooves 13 and the first circular groove 8 do not contact each other; a third spring 14 is fixedly connected to the bottom center of the second circular groove 13; the upper end of the third spring 14 is fixedly connected to the lower surface of the telescopic tube 15; a suction cup 16 is fixedly connected to the upper end of the telescopic tube 15; the circumferential surface of the suction cup 16 in the second circular groove 13 is fixedly connected to the inner wall of the second circular groove 13; the suction cup 16 is connected to the telescopic tube 15 by a design ; The suction cup 16 is fixedly connected to the upper surface of the shell 1 at the part extending out of the circumference of the shell 1; the shell 1 is provided with a plurality of third slide grooves 17 around the second circular groove 13; the cross section of the third slide groove 17 is L-shaped; the upper part of the third slide groove 17 passes through the upper surface of the shell 1, and the upper part of the third slide groove 17 is located in the space formed by the fixed connection between the circumference of the suction cup 16 and the upper surface of the shell 1; a slide rod 18 is slidably connected in the third slide groove 17; the slide rod 18 is designed to extend out of the third slide groove 17 in the vertical direction, and the slide rod 18 does not contact the suction cup 16; the slide rod 18 is fixedly connected to the lower side wall of the telescopic tube 15 at one end of the horizontal part;

[0038] When working, in the initial state, the elastic force of the third spring 14 is greater than the gravity of the telescopic tube 15, the gravity of the suction cup 16 and the friction between the slide bar 18 and the third slide groove 17, so that the upper surface of the slide bar 18 on the horizontal part contacts the upper surface of the third slide groove 17 on the horizontal part;

[0039] When the mobile phone is clamped by the bracket 4, first, the back of the mobile phone contacts the suction cup 16, and a closed space is formed between the back of the mobile phone, the suction cup 16 and the telescopic tube 15. When the mobile phone is pressed down by the clamping rod 43, the mobile phone squeezes the suction cup 16, and the suction cup 16 squeezes the slide bar 18. Because the pulling force of the second spring 6 on the clamping rod 43 and the gravity of the mobile phone are greater than the supporting force of the third spring 14 on the telescopic tube 15 and the friction between the slide bar 18 and the inner wall of the third slide groove 17, the slide bar 18 moves downward inside the third slide groove 17. When the lower surface of the slide bar 18 contacts the third slide groove 17 at the horizontal part, the slide bar 18 moves downward inside the third slide groove 17. When the lower surface of the mobile phone is partially exposed, the upper end of the slide bar 18 completely enters the third slide groove 17. Because the slide bar 18 drives the telescopic tube 15 to move downward in the second circular groove 13, the internal space of the suction cup 16 and the telescopic tube 15 increases, and a closed space is formed between the telescopic tube 15, the suction cup 16 and the back of the mobile phone. At this time, due to the increase in the space formed inside the suction cup 16 and the telescopic tube 15, the internal air pressure of the closed space formed between the telescopic tube 15, the suction cup 16 and the back of the mobile phone is reduced, forming a negative pressure, so that the suction cup 16 can tightly adsorb the back of the mobile phone, thereby preventing the mobile phone from falling and strengthening the surface connectivity between the mobile phone and the wireless mobile power bank.

[0040] As an embodiment of the present invention, a fourth slide groove 19 is provided below the first slide groove 2 on the side wall close to the second circular groove 13, and the length direction of the fourth slide groove 19 is parallel to the length direction of the first slide groove 2; the fourth slide groove 19 is located at the end away from the first spring 3, and the fourth slide groove 19 is connected to the first slide groove 2; an air cavity 21 is provided inside the shell 1; one end of the air cavity 21 is connected to the fourth slide groove 19, and the other end is connected to the second circular groove 13; the air cavity 21 is connected to the inside of the telescopic tube 15 through a conduit 211; the fourth slide groove 19 is elastically connected to a pressure plate 23 on the side wall away from the first spring 3 through a plurality of fourth springs 22 that are evenly fixed; the pressure plate 23 is fixedly connected to a rubber plug 24 on the surface of the side close to the air cavity 21; one end 23 of the pressure plate extends into the first slide groove 2;

[0041] During operation, in the initial state, the elastic force of the fourth spring 22 on the pressure plate 23 and the friction between the rubber plug 24 and the inner wall of the fourth slide groove 19 are greater than the thrust of the rubber plug 24 by the air pressure generated by the suction cup 16 and the internal space of the telescopic tube 15 after the mobile phone presses down the suction cup 16, so that the rubber plug 24 is closely attached to the connection between the fourth slide groove 19 and the air cavity 21, so that the air cavity 21 and the fourth slide groove 19 are mutually sealed;

[0042] When the mobile phone needs to be removed, the bracket 4 is pushed to move in a direction away from the first spring 3. Since the force exerted by manpower on the bracket 4 is greater than the pulling force of the first spring 3 on the bracket 4, the friction between the bottom of the bracket 4 and the inner wall of the first slide groove 2, the friction between the side walls of the slider 41 and the rubber strip 12, the elastic force of the fourth spring 22 on the pressure plate 23, the friction between the rubber plug 24 and the inner wall of the air cavity 21, and the friction between the pressure plate 23 and the inner wall of the fourth slide groove 19, the bracket 4 pushes the pressure plate 23 to move in a direction away from the first spring 3, and the pressure plate 23 drives the rubber plug 24 to move in a direction away from the air cavity 21, so that the air cavity 21 and the fourth slide groove 19 are connected to each other, so that the gas passes through the air cavity 21 through the conduit 211 into the enclosed space formed between the suction cup 16 and the telescopic tube 15 and the back of the mobile phone, so that the suction cup 16 and the telescopic tube 15 are close to the mobile phone. The air pressure inside the enclosed space formed between the back of the mobile phone increases, so that the suction cup 16 is separated from the back of the mobile phone, and the mobile phone is taken off smoothly, so as to avoid the suction cup 16 sucking the mobile phone after the mobile phone is charged, which makes it difficult to take off the mobile phone, and the suction cup 16 is easily damaged when the mobile phone is forcibly pulled off; after the mobile phone is taken off, the bracket 4 is loosened, so that the first spring 3 pulls the bracket 4 to move in the direction of the first spring 3. At this time, because the elastic force of the fourth spring 22 is greater than the friction between the pressure plate 23 and the inner wall of the fourth slide groove 19, and the friction between the rubber plug 24 and the inside of the air cavity 21, the fourth spring 22 pushes the pressure plate 23, and the pressure plate 23 drives the rubber plug 24 to move in the direction of the first spring 3, so that the rubber plug 24 is smoothly inserted into the inside of the air cavity 21, so that the next time the wireless mobile power supply charges the mobile phone, the suction cup 16 can tightly adsorb the back of the mobile phone, effectively improving the prevention of the mobile phone from falling.

[0043] As an embodiment of the present invention, the housing 1 is made of thermally conductive plastic;

[0044] When working, the shell 1 is formed by PP material after mold casting, and has good thermal conductivity, so that the heat generated by the mobile phone during operation is quickly transferred to the shell 1, and the heat is dissipated to avoid heat accumulation, which causes the temperature of the mobile phone and the wireless mobile power supply to be too high and cause safety hazards. At the same time, the mobile phone and the wireless mobile power supply are effectively cooled, the service life of the mobile phone and the wireless mobile power supply is extended, and the use cost is reduced.

[0045] The specific implementation process is as follows:

[0046] In the initial state, because the lower end of the rotating rod 42 is hinged with the upper end of the sliding block 41, the clamping rod 43 extends into the inner part of the groove 7 in the vertical direction at one end in the horizontal direction, and the first spring 3 is in a stretched state, so that the rotating rod 42 and the clamping rod 43 are locked under the action of the first spring 3; the rotating rod 42 and the clamping rod 43 are parallel to the upper surface of the housing 1 on the side away from the first spring 3; because the elastic force of the third spring 14 is greater than the gravity of the telescopic tube 15, the gravity of the suction cup 16, and the sliding rod 18 and the third sliding groove The friction between the fourth spring 22 and the pressure plate 23 makes the slide bar 18 contact the third slide groove 17 on the upper surface of the horizontal part; because the elastic force of the fourth spring 22 on the pressure plate 23 and the friction between the rubber plug 24 and the inner wall of the fourth slide groove 19 are greater than the thrust of the air pressure generated by the suction cup 16 and the internal space of the telescopic tube 15 on the rubber plug 24 after the mobile phone presses down the suction cup 16, the rubber plug 24 is closely attached to the connection between the fourth slide groove 19 and the air cavity 21, so that the air cavity 21 and the fourth slide groove 19 are mutually sealed;

[0047] When the user uses the wireless mobile power bank to charge the mobile phone, the user first bends the clamping rod 43 so that the clamping rod 43 drives the rotating rod 42 to be in a vertical state, and releases the lock of the rotating rod 42 and the clamping rod 43. At this time, because the elastic force of the first spring 3 is greater than the friction between the slider 41 and the bottom of the first slide groove 2, the first spring 3 drives the bracket 4 to move away from the groove 7; after the bracket 4 stops moving, the bracket 4 is bend, because the force exerted by the person on the bracket 4 is greater than the pulling force of the first spring 3 on the bracket 4 and the friction between the bottom of the bracket 4 and the first slide groove 2, the bracket 4 moves in the direction away from the first spring 3. At this time, the mobile phone is placed in the clamping space formed by the bracket 4, and then the clamping rod 43 is pulled upward. Because the force exerted by the human power on the clamping rod 43 is greater than the pulling force of the second spring 6 on the clamping rod 43, the friction between the clamping rod 43 and the side wall of the second slide groove 5 and the gravity of the clamping rod 43, the clamping rod 43 moves upward to the inside of the second slide groove 5 The clamping rod 43 moves in the horizontal direction. When the clamping rod 43 moves to the top of the mobile phone on the lower surface of the horizontal part, the clamping rod 43 is released. Since the pulling force of the second spring 6 on the clamping rod 43 is greater than the friction between the clamping rod 43 and the inner wall of the second slide groove 5, the clamping rod 43 is in close contact with the surface of the mobile phone on the lower surface in the horizontal direction. After that, the bracket 4 and the clamping rod 43 are pulled in sequence, so that the clamping rod 43 at each position is in close contact with the surface of the mobile phone on the lower surface of the horizontal part, thereby fixing the mobile phone on the outer surface of the wireless mobile power supply, ensuring that the mobile phone does not need to be placed on a flat surface or manually held when charging, so that the user can continue to use the mobile phone while charging, effectively improving the practicality of the wireless mobile power supply, and preventing the mobile phone from falling from the surface of the wireless mobile power supply. The first slide groove 2 is elastically connected with the bracket 4 through the first spring 3, so that the bracket 4 can slide inside the first slide groove 2, so that the bracket 4 can clamp mobile phones of different sizes, effectively improving the practicality of the wireless mobile power supply.

[0048] When the mobile phone is clamped by the bracket 4, first, the back of the mobile phone contacts the suction cup 16, and a closed space is formed between the back of the mobile phone, the suction cup 16 and the telescopic tube 15. When the mobile phone is pressed down by the clamping rod 43, the mobile phone squeezes the suction cup 16, and the suction cup 16 squeezes the slide bar 18. Because the pulling force of the second spring 6 on the clamping rod 43 and the gravity of the mobile phone are greater than the supporting force of the third spring 14 on the telescopic tube 15 and the friction between the slide bar 18 and the inner wall of the third slide groove 17, the slide bar 18 moves downward inside the third slide groove 17. When the lower surface of the slide bar 18 contacts the third slide groove 17 at the horizontal part, the slide bar 18 moves downward inside the third slide groove 17. When the lower surface of the part is touched, the upper end of the slide bar 18 completely enters the third slide groove 17. Because the slide bar 18 drives the telescopic tube 15 to move downward toward the lower part of the second circular groove 13, the internal space of the suction cup 16 and the telescopic tube 15 increases, and a closed space is formed between the telescopic tube 15, the suction cup 16 and the back of the mobile phone. At this time, due to the increase in the space formed inside the suction cup 16 and the telescopic tube 15, the internal air pressure of the closed space formed between the telescopic tube 15, the suction cup 16 and the back of the mobile phone decreases, forming a negative pressure, so that the suction cup 16 can tightly adsorb the back of the mobile phone, thereby preventing the mobile phone from falling, and strengthening the surface connectivity between the mobile phone and the wireless mobile power supply;

[0049] When the mobile phone needs to be removed, the bracket 4 is pushed to move in a direction away from the first spring 3. Since the force exerted by manpower on the bracket 4 is greater than the pulling force of the first spring 3 on the bracket 4, the friction between the bottom of the bracket 4 and the inner wall of the first slide groove 2, the friction between the side walls of the slider 41 and the rubber strip 12, the elastic force of the fourth spring 22 on the pressure plate 23, the friction between the rubber plug 24 and the inner wall of the air cavity 21, and the friction between the pressure plate 23 and the inner wall of the fourth slide groove 19, the bracket 4 pushes the pressure plate 23 to move in a direction away from the first spring 3, and the pressure plate 23 drives the rubber plug 24 to move in a direction away from the air cavity 21, so that the air cavity 21 and the fourth slide groove 19 are connected to each other, so that the gas passes through the air cavity 21 through the conduit 211 into the enclosed space formed between the suction cup 16 and the telescopic tube 15 and the back of the mobile phone, so that the suction cup 16 and the telescopic tube 15 are close to the mobile phone. The air pressure in the enclosed space formed between the back of the mobile phone increases, so that the suction cup 16 is separated from the back of the mobile phone, and the mobile phone is taken off smoothly, so as to avoid the suction cup 16 sucking the mobile phone after the mobile phone is charged, which makes it difficult to take off the mobile phone, and the suction cup 16 is easily damaged when the mobile phone is forcibly pulled off; after the mobile phone is taken off, the bracket 4 is loosened, so that the first spring 3 pulls the bracket 4 to move in the direction of the first spring 3. At this time, because the elastic force of the fourth spring 22 is greater than the friction between the pressure plate 23 and the inner wall of the fourth slide groove 19, and the friction between the rubber plug 24 and the inside of the air cavity 21, the fourth spring 22 pushes the pressure plate 23, and the pressure plate 23 drives the rubber plug 24 to move in the direction of the first spring 3, so that the rubber plug 24 is smoothly inserted into the inside of the air cavity 21, so that the next time the wireless mobile power supply charges the mobile phone, the suction cup 16 can tightly adsorb the back of the mobile phone, effectively improving the prevention of the mobile phone from falling;

[0050] After the mobile phone is clamped by the bracket 4, the multiple rubber blocks 11 uniformly connected to the rotating rod 42 and the clamping rod 43 on the surface of one side close to the first spring 3 can increase the friction between the side wall of the mobile phone and the rotating rod 42 and the clamping rod 43, effectively preventing the mobile phone from sliding and falling. The multiple rubber blocks 11 uniformly connected to the lower surface of the horizontal part of the clamping rod 43 can increase the friction between the mobile phone use surface and the clamping rod 43, and prevent the clamping rod 43 from directly contacting the mobile phone use surface on the lower surface in the horizontal direction, thereby effectively preventing the clamping rod 43 from scraping the mobile phone use surface, so that while increasing the friction between the mobile phone and the bracket 4, the mobile phone screen is effectively protected from being worn;

[0051] After charging the mobile phone, first stretch the clamping rod 43 upward, then move the bracket 4 away from the first spring 3 to take out the mobile phone, and the first spring 3 drives the bracket 4 to reset; then, move the bracket 4 to move away from the first spring 3, and then move the clamping rod 43 so that the clamping rod 43 drives the rotating rod 42 to move toward the inside of the groove 7, so that the clamping rod 43 enters the inside of the groove 7 in the vertical direction at one end in the horizontal direction, thereby restoring the wireless mobile power supply to the initial state, effectively preventing the bracket 4 from extending out of the groove 7, affecting the appearance of the wireless mobile power supply, and making the wireless mobile power supply inconvenient to carry; The rubber strips 12 on the side walls of the first slide groove 2 are inclined toward the groove 7, and the rubber strips 12 are in contact with the side walls of the slider 41. At the same time, because the pulling force of the first spring 3 on the bracket 4 is greater than the friction between the bottom of the bracket 4 and the inner wall of the first slide groove 2 and the friction between the side walls of the slider 41 and the rubber strips 12, the first spring 3 pulls the bracket 4 to reset. Because the friction between the side walls of the slider 41 and the rubber strips 12 is generated, the first spring 3 is effectively prevented from pulling the bracket 4 to reset quickly, thereby preventing the bracket 4 from hitting a person's hand, effectively improving the safety protection performance of the wireless mobile power supply, and preventing the bracket 4 from being worn and affecting the normal use of the wireless mobile power supply.
