[0001] This utility model relates to the field of electronic device charging equipment technology, specifically to a vehicle-mounted air vent anti-loss charger. Background Technology

[0002] Wireless charging technology is becoming increasingly mature in electronic product chargers, and wireless chargers are becoming more and more common. Wireless chargers are devices that charge based on the principle of electromagnetic induction. They work by installing a set of coils at both the transmitting and receiving ends. The transmitting coil sends electromagnetic signals to the outside world under the action of electricity, and the receiving coil converts the received electromagnetic signals into current, thereby achieving the purpose of wireless charging.

[0003] A car wireless charger is a type of charger used in motor vehicles to allow drivers to conveniently charge electronic devices while driving. However, the function of car chargers is relatively limited, only capable of charging electronic devices. Common chargers offer no assistance in helping drivers locate their vehicles. For example, when a vehicle is parked in a large or unfamiliar parking lot, it can be difficult for the driver to quickly and accurately locate the vehicle. Therefore, to meet diverse usage needs, there is an urgent need for a wireless charger that can be located and prevent loss.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0031] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0032] In this embodiment of the utility model, a charger with anti-loss function is provided for vehicle mounting and installed on the air conditioning vent. The charger can be installed at the air conditioning vent of the car via a fixing base 100 for wireless charging of mobile phones. It also has an anti-loss device 300 that wirelessly connects with the mobile phone, which can locate the car in a large parking lot. In addition, when the charger is forgotten, it can be located by sound generated by the sound-emitting component 310 on the anti-loss device 300, thereby improving the performance of the charger.

[0033] like Figure 1-3 As shown in the present invention, an anti-loss charger for vehicle air vents is provided, including a fixed base 100 and a charging base 200 movably connected to the fixed base 100. The fixed base 100 includes a retainer 110 with a ball head 101. The charging base 200 includes a housing 210, a wireless charging module 220, and an anti-loss device 300. One side of the housing 210 is formed with a mounting cavity 211 movably connected to the ball head 101. The mounting cavity 211 has an arc-shaped inner cavity surface that is adapted to the ball head 101. The wireless charging module 220 and the magnetic suction component 230 are installed inside the housing 210. Meanwhile, the anti-loss device 300 is fixedly installed inside the housing 210 and has a built-in wireless connection module for wireless connection with mobile devices. A sound-emitting component 310 is also provided on the anti-loss device 300.

[0034] During use, the mounting base 100 and the charging base 200 are movably connected to the mounting cavity 211 via the ball head 101. This allows the charging base 200 to swing at multiple angles after the charger is mounted to the car's air conditioning vent via the mounting base 100, making it more convenient to use. At the same time, the magnetic component 230 attracts the phone to the surface of the phone, thus attaching the phone to the end face of the charging base 200. Then, the wireless charging module 220 wirelessly charges the phone via the receiving coil on the phone. When a driver parks their vehicle in a large parking lot and it is inconvenient to find, the anti-loss device 300 can be used to locate it. In this embodiment, the wireless connection module built into the anti-loss device 300 can be a Bluetooth communication module or a wireless communication module. Similarly, it can also be other existing technologies that can achieve wireless communication with mobile devices. This is not limited here. This technical solution allows technicians to easily and quickly locate the vehicle using the anti-loss device 300. On the other hand, when the charger provided in this embodiment is removed from the vehicle and placed in another location and cannot be found, the sound emitted by the sound-emitting component 310 in the anti-loss device 300 can be used to locate the anti-loss device 300, thereby easily and quickly locating the specific location of the charger. In this embodiment, the sound-emitting component 310 can be a buzzer or a speaker component. In this embodiment, it can also be other existing technologies that can emit sound. This is not limited here. The technical solution provided by this utility model embodiment not only enables wireless charging of mobile devices, but also helps drivers find their vehicles quickly and easily. Furthermore, if the charger is lost or its location forgotten, it helps users quickly locate the charger and provides a prompt sound from the sound-emitting component 310 to assist in finding it. This improves the charger's performance and makes it more convenient for users.

[0035] In this embodiment, as Figure 2As shown, the housing 210 provided in this embodiment includes a bottom shell 212 and a top cover 213. Specifically, a mounting cavity 211 is formed on the back of the bottom shell 212, and a chamber 2121 is formed on the front of the bottom shell 212. The anti-loss device 300 and the power supply are installed inside the chamber 2121. The top cover 213 covers the chamber 2121 and seals the chamber 2121. An annular groove 2131 and a mounting groove 2132 located at the center of the annular groove 2131 are formed on the top cover 213. The magnetic suction component 230 is installed inside the annular groove 2131. The wireless charging module 220 includes a charging coil 221 fixedly installed inside the mounting groove 2132 and a wireless charging circuit board 222 fixedly installed inside the chamber 2121 and electrically connected to the charging coil 221. The housing 210 is also provided with a plug interface for plugging into an external power source. The wireless charging circuit is electrically connected to the plug interface.

[0036] In this embodiment, the anti-loss device 300 is fixedly installed inside the cavity 2121 of the bottom shell 212, thereby enabling the anti-loss device 300 to be securely installed and protected by the shell 210. The charging coil 221 is installed inside the mounting groove 2132 of the top cover 213, and the magnetic suction component 230 is fixedly installed inside the annular groove of the top cover 213. This reduces the distance between the charger and the mobile device, allowing the charging coil 221 to more quickly conduct electromagnetic induction with the receiving coil located inside the mobile device. In other words, the magnetic lines of force generated by the charging coil 221 can pass through the receiving coil, so that an induced current is generated in the receiving coil, thereby completing the wireless charging of the mobile device.

[0037] In this embodiment, in order to reduce interference with the magnetic induction lines and to protect the charging coil 221 and magnetic attraction component 230 mounted on the upper cover 213, the housing 210 is further provided with a rubber pad 214. The rubber pad 214 is fixedly mounted on the upper cover 213 and closes the mounting groove 2132 and the annular groove 2131.

[0038] In this embodiment, as Figure 2As shown in the illustration, this embodiment provides an example of the structure of the anti-loss device 300. The anti-loss device 300 includes a PCB board 301 and a power supply device 302. The PCB board 301 and the power supply device 302 are electrically connected, and the wireless connection module and the sound-generating component 310 are electrically connected to the PCB board 301. In this embodiment, a protection circuit and a positioning module are provided on the PCB board 301, thereby providing startup power through the protection circuit and the positioning module. After wireless connection with the mobile device, the positioning module can realize the positioning function of the anti-loss device 300. In this embodiment, the technical solution of the anti-loss device 300 can be implemented by existing technology, such as the technical solution of the anti-loss device 300 provided in the Bluetooth anti-loss device 300 provided in announcement number CN217464813U. Specifically, the PCB board 301 in this technical solution can be implemented using the control device with Bluetooth function in the anti-loss device 300 provided in announcement number CN217464813U. Similarly, other technical solutions in the prior art can also be used.

[0039] During use, the mobile device wirelessly connects to the anti-loss device 300 via the wireless connection module. During the search process, the positioning module can locate the position of the anti-loss device 300, and the device can be located by combining the prompts emitted by the sound-emitting component 310 set on the PCB board 301.

[0040] In this embodiment, to charge the anti-loss device 300, the PCB board 301 is electrically connected to the interface to charge the power supply device 302. During use, while wirelessly charging the mobile device, the power supply device 302 of the anti-loss device 300 can be charged simultaneously. In this embodiment, the power supply device 302 is implemented using a rechargeable battery; similarly, other existing technical solutions can also be used.

[0041] In this embodiment, the fixture 110 is used to install the charger at the air vent of the car. It is worth noting that the air vent has a grille for changing its direction, and the fixture 100 clamps the grille to enable the charger to be installed. Figure 3As shown, the retainer 110 includes a screw 111, grippers 113, and a locking nut 114. Specifically, a ball head 101 is fixedly provided at one end of the screw 111, and a rotating shaft 112 extending radially is provided at the other end; the grippers 113 include two symmetrically arranged grippers, the upper end of which is formed with a hinge portion 1131. The hinge portions 1131 of the two grippers 113 are rotatably connected to the rotating shaft 112, and a actuating portion 1132 is provided on the outer side of the grippers 113 to actuate the grippers 113 to swing along the rotating shaft 112; the locking nut 114 is located between the jaw 113 and the ball head 101 and is threaded onto the screw 111. Rotating the locking nut 114 causes it to move along the axis of the screw 111 and switch between a locked state and a released state. When the locking nut 114 is rotated and in the locked state, the locking nut 114 abuts against the upper end of the jaw 113, restricting the jaw 113 from swinging around the rotating shaft 112. When the locking nut 114 is rotated and in the released state, the locking nut 114 separates from the upper end of the jaw 113 and provides space for the jaw 113 to swing around the rotating shaft 112.

[0042] During the installation of the mounting base 100 at the air outlet position, the two grippers 113 are actuated by the actuating part 1132 to rotate along the rotating shaft 112, thereby separating the free ends of the grippers 113 from each other. This allows the grille strip from the air conditioning outlet to be positioned between the two grippers 113. Subsequently, after pushing the actuating part 1132, the free ends of the two grippers are separated, and the locking nut 114 is screwed in. This causes the end of the locking nut 114 to abut against the upper end face of the gripper 113, thus switching to the locked state of the locking nut 114. At this time, since the locking nut 114 abuts against the upper end of the gripper 113, the free end of the gripper 113 can be restricted from rotating along the rotating shaft 112, thereby achieving the clamping action between the gripper 113 and the grille strip, and thus installing the mounting base 100 at the air conditioning outlet position.

[0043] In this embodiment, to prevent wear on the locking nut 114 during the locking of the jaws 113, a washer 115 is sleeved on the screw 111. The washer 115 is located between the locking nut 114 and the jaws 113. When the locking nut 114 is in the locked state, the washer 115 abuts against the upper end of the jaws 113. In this embodiment, the washer 115 is made of metal, which can press the jaws 113 tightly and reduce wear when locked. In other embodiments, other wear-resistant materials can also be used, and there is no limitation here.

[0044] In this embodiment, to increase the clamping force of the two jaws 113 clamping the grid strip, a locking ramp 1133 is formed on the top of the upper end of the jaws 113. The locking ramp 1133 is gradually inclined downward from the outside to the inside of the jaws. As the clamping nut 2124 is gradually tightened, the washer 115 gradually presses against the upper end of the jaws 113, allowing the jaws 113 to gradually rotate along the shaft 112. At this time, the locking ramp 1133 can gradually be converted to a state parallel to the plane of the washer 115. At this time, the free end of the jaws 113 can gradually swing towards the grid strip. After the locking ramps 1133 on the two jaws 113 form a surface that is parallel to and overlaps with the surface of the washer 115, the free ends of the two jaws 113 are inclined towards each other, thereby clamping the grid strip and ensuring the stability of the fixing seat 100 installed on the grid strip.

[0045] To further ensure the stability of the mounting base 100 when installed at the air outlet, a clamping arm is defined at the lower end of the clamping claw 113, and a hook portion 1135 is formed at the lower end of the clamping arm facing the other clamping arm. The hook portion 1135 can hook the inner edge of the grille strip, thereby preventing the clamping claw 113 from slipping off the grille strip.

[0046] In this embodiment, as Figure 1-3 As shown, a specific example of the connection structure between the fixing base 100 and the charging base 200 is given. A plurality of elastic arms 2123 are formed on the housing 210 at equal angles and arranged in a ring. The interior of the plurality of elastic arms 2123 defines a mounting cavity 211 for the ball head 101 to be placed therein. External threads are provided on the outer cylindrical surface defined by all the elastic arms 2123, and clamping nuts 2124 are threadedly connected thereto. The outer end of the elastic arm 2123 is provided with a clamping slope 2125 that is inclined toward the axis of the mounting cavity 211. The outer end of the clamping nut 2124 is provided with a constriction structure corresponding to the clamping slope 2125, which is used to press the clamping slope 2125 toward the axis of the mounting cavity 211.

[0047] During the connection of the mounting base 100 and the charging base 200, the ball head 101 is positioned within the mounting cavity 211 defined by multiple elastic arms 2123. Since the mounting cavity 211 has an arc-shaped inner surface, the relative position of the mounting base 100 and the charging base 200 can be changed by rotating the ball head 101, thereby providing more usable angles. Subsequently, after tightening the clamping nut 2124, the clamping inclined surface 2125 applies pressure to the elastic arms 2123 in the axial direction, causing the elastic arms 2123 to generate a clamping force in the axial direction, clamping the ball head 101 located within the mounting cavity 211, thereby fixing the ball head 101, that is, fixing the position and angle of the charging base 200, making it more convenient for users to use.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
