Description

Technical Field

[0001] This utility model relates to the field of wireless charger technology, specifically a wireless charger with protective functions. Background Technology

[0002] As electrical devices increasingly demand higher requirements for power quality, safety, reliability, convenience, immediacy, and suitability for special occasions and geographical environments, traditional power transmission methods are becoming increasingly inadequate to meet practical needs. Wireless chargers, which utilize the principle of electromagnetic induction, work similarly to transformers. By placing a coil at both the transmitting and receiving ends, the transmitting coil emits electromagnetic signals under the influence of electricity, while the receiving coil receives and converts these signals into current, thus achieving wireless charging. Existing wireless chargers have simple and relatively fragile casings, primarily designed to enclose internal electronic components and provide installation space. If accidentally dropped, the casing may break or internal electronic components may detach or be damaged, affecting the normal operation of the entire wireless charger and failing to provide adequate protection for the internal wireless charging module and related electronic components.

[0003] For example, the wireless charger with protective function disclosed in the patent announcement number CN 219018544 U, although it provides a wireless charger with protective function to solve the problem mentioned in the background art that the wireless charger shell structure is simple and easily damaged by drops, it does not solve the problem that existing wireless chargers generate a lot of heat during use, and existing wireless chargers do not have effective heat dissipation components, which may lead to overheating of the wireless charger, making it unusable or even posing a fire risk. Utility Model Content

[0004] The purpose of this invention is to provide a wireless charger with protective functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wireless charger with protective function includes a charging protection mechanism. The charging protection mechanism includes a top cover, a magnet mounting cavity, a power-off protector, and a connecting wire. The charging protection mechanism includes a top cover, a magnet mounting cavity inside the top cover, a power-off protector on one side of the top cover, and a connecting wire on one side of the power-off protector.

[0007] The top cover is provided with a charger protection mechanism at its bottom end. The charger protection mechanism includes a main body shell, an anti-slip bottom pad, a spring rod mounting cavity, and a stabilizing spring rod. The charger protection mechanism includes a main body shell, an anti-slip bottom pad at the bottom end of the main body shell, a spring rod mounting cavity inside the main body shell, and a stabilizing spring rod fixedly installed inside the spring rod mounting cavity.

[0008] Preferably, the stabilizing spring rod includes a mounting base plate, a shock-absorbing spring rod is provided at the top of the mounting base plate, and a wireless charging module support plate is provided at the top of the shock-absorbing spring rod. The advantage is that by providing a stabilizing spring rod inside the spring rod mounting cavity, if the wireless charger is dropped, the shock-absorbing spring rod is supported by the mounting base plate, and the wireless charging module at the bottom is supported by the wireless charging module support plate. This can effectively reduce the damage to the wireless charging module support plate during a drop.

[0009] Preferably, a wireless charging module is provided on one side of the power failure protector, and a magnetic attraction module is fixedly provided inside the magnet mounting cavity. The advantage is that the device to be charged is fixed on the surface of the wireless charger by the magnetic attraction module. The power failure protector connects to the external connecting wire, and the wireless charging module charges the device. Furthermore, if an abnormal voltage occurs during the charging process, the power failure protector can quickly disconnect the connection between the connecting wire and the wireless charging module to prevent fire caused by abnormal current and voltage.

[0010] Preferably, the main body shell and the top cover are respectively provided with a top cover fixing screw hole and a shell fixing screw hole. The advantage is that the top cover and the main body shell can be fixed together by fixing screws.

[0011] Preferably, the top cover fixing screw hole and the housing fixing screw hole are connected and fixed by a number of fixing screws. The advantage is that it can effectively ensure the stability of the charger structure and improve the safety during use.

[0012] Preferably, the wireless charging module support plate includes a thermal pad, which is fixed to the bottom of the top cover through the support plate screw holes. The advantage is that, while effectively ensuring the stability of the charger, the thermal pad can effectively conduct the heat generated during the charging of the wireless charging module to the main body shell through the bottom conductive damping spring rod and the mounting base plate, and then dissipate heat by contacting the external cold air.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This wireless charger with protective function is first fixed to the bottom of the top cover through the screw holes of the support plate. Then, the main body shell is installed together with the top cover through the fixing screws, the fixing screw holes of the top cover and the fixing screw holes of the shell. Then, charging can be started. During the charging process, the external connecting wire is connected through the power-off protector to charge the device through the wireless charging module. If an abnormal voltage occurs during the charging process, the power-off protector can quickly disconnect the connection between the connecting wire and the wireless charging module to prevent the problem of fire caused by abnormal current and voltage.

[0015] 2. The advantage of this wireless charger with protective function is that existing wireless chargers generate a lot of heat during use, and they do not have effective heat dissipation components. This may lead to overheating of the wireless charger, causing it to become unusable or even posing a fire risk. Therefore, a wireless charger with protective function is proposed. By using a stabilizing spring rod, the stability of the internal components of the wireless charger is improved, and heat dissipation can be effectively achieved, thus improving the practicality of the charger.
