Description

Technical Field

[0001] This invention relates to the field of wireless charging technology, and more particularly to a portable in-vehicle wireless charger. Background Technology

[0002] With the widespread use of smartphones in daily life and while driving, especially the heavy reliance on navigation, communication, and entertainment functions during long-distance driving, in-car charging devices have become an indispensable accessory for car owners. In-car wireless chargers, due to their advantages such as eliminating the need for plugging and unplugging data cables, ease of operation, and the ability to easily access and place the phone, are gradually replacing traditional wired charging methods and becoming the mainstream choice in the market. Currently, these products typically draw power from the car's cigarette lighter or USB port, and combine a bracket and clamping structure to stably fix the phone within the driver's field of vision. They also utilize electromagnetic induction to achieve wireless charging, effectively ensuring the battery life of electronic devices while driving.

[0003] However, existing in-vehicle wireless chargers still have significant shortcomings in practical use. First, their brackets and wireless charging modules mostly use threaded connections, making disassembly inconvenient and difficult to quickly separate and carry. Furthermore, most products lack integrated energy storage batteries, meaning they cannot provide independent power after being disconnected from the vehicle's power supply. This forces users to rely on external power to continue using the charging function after leaving the vehicle, limiting their usage scenarios. Second, current products generally lack support for multi-device compatible charging. For example, while wirelessly charging a mobile phone, they cannot wiredly charge small electronic devices such as Bluetooth headsets and smartwatches, failing to meet users' diverse charging needs in mobile scenarios. Therefore, we propose a portable in-vehicle wireless charger to solve these problems. Summary of the Invention

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0028] A portable wireless car charger, such as Figures 1-5As shown, the device includes a wireless charger body 1, which contains a rechargeable battery 102. A support block 2 is fixedly installed on the bottom of the casing on the charging side of the wireless charger body 1. Multiple rails 101 are fixedly installed on the casing on the side of the wireless charger body 1 away from the charging side. It also includes clamps 3 symmetrically installed on the left and right sides of the wireless charger body 1. The clamps 3 have hooks at their ends facing the charging side. A mounting rod 31 is fixedly connected inside the wireless charger body 1, and the clamps 3 are slidably mounted on the mounting rod 31. A spring 32 is provided between the wireless charger body 1 and the clamps 3. A support frame 4 is provided on one side of the wireless charger body 1 to support it. The support frame 4 includes a connecting frame 41, a first connecting block 42, and a second connecting block 43. One end of the connecting frame 41 is hinged to a connecting block 42. The connecting block 42 has a slot 421 for fitting the rail 101, so that the wireless charger body 1 can be easily installed onto the connecting block 42 of the support frame 4 via the rail 101. The other end of the connecting frame 41 is hinged to a connecting block 43. The shafts of the connecting frame 41 that are hinged to the connecting blocks 42 and 43 are provided with first screw knobs 44. The first screw knobs 44 are threaded to lock the connecting blocks 42 and 43 respectively. The first screw knobs 44 are used to adjust the shape of the support frame 4. The wireless charger body 1 is provided with a power cord 5 for power supply. The end of the support frame 4 away from the wireless charger body 1 is provided with a fixing mechanism 9. The fixing mechanism 9 is used to fix the support frame 4 to the vehicle position.

[0029] like Figures 6-8 As shown, the wireless charger body 1 has a charging port 52 inside that is compatible with the power cord 5. The top of the connecting block 42 has an opening corresponding to the charging port 52. The plug 51 of the power cord 5 passes through the opening of the connecting block 42 and is inserted into the charging port 52. The outer shell of the plug 51 is square and fits perfectly into the opening of the connecting block 42. When the plug 51 is inserted into the wireless charger body 1, the wireless charger body 1 can be stably fixed on the connecting block 42 by the plug 51, thereby improving the stability of the wireless charger body 1 when it is snapped into the connecting block 42.

[0030] like Figure 5 and Figure 6 As shown, a sliding plate 6 is slidably connected inside the wireless charger body 1 via a guide rod 61. Two connecting plates 62 are hinged to one end of the sliding plate 6. The connecting plate 62 is hinged to the corresponding clamp 3 on the same side. An electric turntable 63 is fixedly installed inside the wireless charger body 1. A protruding rod 64 is eccentrically provided on the electric turntable 63. A connecting groove 601 is opened inside the sliding plate 6, and the protruding rod 64 is located in the connecting groove 601 of the sliding plate 6.

[0031] like Figure 6As shown, a trigger switch 7 is provided on one side of the wireless charger body 1. The trigger switch 7 is electrically connected to the control system of the electric turntable 63. The trigger switch 7 can control the electric turntable 63 to rotate forward and backward. The trigger switch 7 is powered by the charging port 52. When the wireless charger body 1 is charging on the support frame 4 through the power cord 5, the user presses the trigger switch 7. The trigger switch 7 can trigger the control system to control the electric turntable 63 to rotate forward through a preset program. The forward rotating electric turntable 63 presses the sliding plate 6 upward through the protruding rod 64. The sliding plate 6 is pushed upward under the guidance of the guide rod 61. The connecting plates 62 on both sides overcome the elastic force of the spring 32 and press the corresponding clamps 3 on the same side, so that the clamps 3 on the wireless charger body 1 automatically open, so that the user can place the charging device on the wireless charger body 1. When the wireless charger body 1 is in place with the charging device, the trigger switch 7 can be pressed again. The trigger switch 7 can trigger the control system and control the electric turntable 63 to reverse and reset through the preset program. Similarly, the sliding plate 6 pulls the clamps 3 on both sides to reset and close through the connecting plates 62, so that the clamps 3 on both sides can automatically clamp the charging device, improving the charging convenience of the wireless charger body 1.

[0032] like Figure 1 and Figure 9 As shown, the fixing mechanism 9 includes a clamping plate 91, a tensioning block 93, and a second lead screw knob 94. The clamping plate 91 has two rotatably mounted pieces on the side of the connecting block 43 away from the connecting frame 41. Magnets 92 are slidably mounted on the opposite ends of the plates of the two clamping plates 91. The magnets 92 can extend and retract into the clamping plate 91, and the magnetism of the two magnets 92 is opposite. A tensioning block 93 is slidably mounted on the connecting block 43, contacting the rotating shaft of the clamping plate 91. The tensioning block 93 is used to limit the clamping plate 91. A second lead screw knob 94 is threadedly mounted on the connecting block 43. The second lead screw knob 94 and the tensioning block 94... When the fastening block 93 is in contact with the support frame 4, and it is necessary to fix the support frame 4 in the vehicle, the air conditioning vent or other plate-shaped position in the car can be selected. First, turn the second screw knob 94 to loosen it. Then, insert the two clamping plates 91 on the connecting block 43 into a guide vane in the air conditioning vent. The two clamping plates 91 close and clamp the guide vane under the magnetic attraction of the magnetic block 92, so that the entire fixing mechanism 9 can be stably limited in the air conditioning vent. Then, tighten the second screw knob 94 to loosen the fastening block 93, so that the fastening block 93 can stably lock the limiting clamping plate 91, so that the fixing mechanism 9 can stably install the support frame 4 in the vehicle.

[0033] like Figure 9 and Figure 10As shown, a replaceable adhesive pad 10 is provided on the plate surface on the opposite side of the clamping plate 91. The adhesive surface of the adhesive pad 10 is covered with a protective film. After turning and loosening the second screw knob 94, the angle between the two clamping plates 91 can be adjusted by turning. After tearing off the protective film on the adhesive pad 10, the two clamping plates 91 can also be glued to flat areas such as the car center console (central instrument panel) through the adhesive pad 10, thereby expanding the use and fixing methods of the fixing mechanism 9.

[0034] When using this wireless charger inside the car, first, operate the fixing mechanism 9 at the end of the support frame 4. For example, insert the two clamps 91 between the air guide vanes of the car's air conditioning vent. The opposite polarity magnetic blocks 92 at the ends of the clamps 91 will attract each other, causing the clamps 91 to automatically close and initially clamp the air guide vanes. Then, tighten the second screw knob 94 and push the tension block 93 to lock the shaft of the clamps 91, thereby fixing the entire support frame 4 onto the air vent grille. If the air vent is not suitable, loosen the second screw knob 94, rotate the two clamps 91 to a flat angle, and then peel off the protective film of the adhesive pad 10 on the clamps 91. Adhere it directly to a flat surface such as the center console. After the support frame 4 is securely installed, align the wireless charger body 1 with the slot 421 of the connecting block 42 at the top of the support frame 4 through the slot 101 on its back, quickly completing the physical connection. Then, thread the square plug 51 of the power cord 5 through... Insert the wireless charger into the charging port 52 of the wireless charger through the port of the connecting block 42. While the power is on, the precise fit between the plug 51 and the port further prevents the wireless charger from loosening during vehicle bumps. After powering on, the user can loosen the first screw knob 44 at both ends of the connecting bracket 41 to freely adjust the tilt angle of the wireless charger to the optimal viewing and charging position. Then, tighten the knob to lock it. Then, press the trigger switch 7 on the side of the wireless charger. The built-in electric turntable 63 starts and drives the sliding plate 6 to move upward through the eccentric protrusion 64. This pushes the connecting plates 62 on both sides to overcome the force of the spring 32, causing the clamps 3 on both sides to open automatically. After placing the wireless charging device such as a mobile phone or tablet, press the trigger switch 7 again. The electric turntable 63 reverses and resets. The sliding plate 6 moves downward and pulls the clamps 3 to close automatically through the connecting plates 62, tightly clamping the charging device between the support block 2 and the hook, and starting stable wireless charging.

[0035] like Figure 6As shown, a top block 8 is fixedly connected to the bottom of the sliding plate 6. The bottom of the wireless charger body 1 has an opening adapted to the top block 8. The top block 8 slides out from the opening of the wireless charger body 1. When the wireless charger body 1 is removed from the support frame 4 for carrying and use, the charging port 52 of the wireless charger body 1 is disconnected from the power cord 5. At this time, the trigger switch 7, which is powered only by the charging port 52, stops working, thereby preventing the clamp 3 from releasing the charging device due to accidental contact of the trigger switch 7 during carrying. When it is necessary to remove the charging device from the wireless charger body 1 while carrying, the user can press the top block 8 upward. The top block 8 drives the sliding plate 6 to move upward. At this time, the sliding plate 6 can also drive the clamps 3 on both sides to open at the same time. After releasing the top block 8, the clamps 3 on both sides can return to the clamping state under the action of the spring 32.

[0036] like Figure 3 As shown, a charging cable 103 is provided on one side of the wireless charger body 1. The charging cable 103 is electrically connected to the battery 102. The charging cable 103 is used to expand the charging methods of the wireless charger body 1, so that the wireless charger body 1 can have both wireless charging and wired charging functions at the same time.

[0037] When the user needs to take the wireless charger out of the vehicle, first unplug the power cord 5 plug 51 from the charging port 52, then gently lift the wireless charger body 1 upwards to separate its rail 101 from the support frame 4. At this time, the wireless charger body 1 switches to an independent power bank mode. In this mode, since the power cord 5 supplying power to the trigger switch 7 is disconnected, the electric control function of the trigger switch 7 is automatically disabled, thus eliminating the risk of accidentally opening the clamp 3 due to accidental contact in a backpack or pocket, causing the device to slip. During carrying, the wireless charger continuously supplies power to the clamped device using the built-in battery 102. When it is necessary to remove the wireless charger... When charging the device on the main body 1, the user does not need to look for a switch. Simply push the exposed top block 8 at the bottom of the wireless charger upwards. The top block 8 directly drives the internal sliding plate 6 to move upwards, mechanically forcing the clamps 3 on both sides to open simultaneously. After removing the charging device, release the top block 8, and the clamps 3 will instantly return to the normally closed clamping state under the action of the spring 32. In addition, the wireless charger main body 1 comes with a wired charging cable 103, which allows it to be used not only as a wireless power bank but also as a traditional wired charger, providing dual power supply for users in various mobile scenarios after leaving the vehicle, achieving seamless connection and flexible power supply from in-vehicle to personal use.

[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
