Technical Field

[0001] The invention relates to the technical field of chargers, and in particular to a mobile phone charger with a charging protection function. Background Art

[0002] Mobile phone chargers can be roughly divided into travel chargers, seat chargers and maintenance chargers. Generally, users are exposed to the first two types, while the most popular ones on the market are travel chargers. Mobile phones have become the main choice for long-distance communication in people's daily lives. At the same time, mobile phones show a trend of diversified functions and have become the mainstream choice for people's entertainment and learning. With the improvement of people's living standards, mobile phones are used more and more frequently in people's daily lives. Existing mobile phones consume a lot of power, and people need to charge their phones frequently. The existing technology has the following problems:

[0003] 1. At present, when charging the device for a long time, the charger will inevitably generate a certain temperature, and the surface temperature of the charger will gradually increase as the charging time increases. If the electronic components cannot be cooled and dissipated from the root, it is easy to cause damage to the electronic components in the charger;

[0004] 2. Chargers generally have the function of reducing the charging speed to avoid damage to the device's battery. However, if the device cannot disconnect itself from the charger in time when the temperature is high, it will also cause certain hidden dangers to the device. Summary of the invention

[0005] The present invention provides a mobile phone charger with a charging protection function, wherein one purpose is to completely cut off the transmission of current when the temperature is too high, so as to solve the problem that if the temperature is too high and the charger is not unplugged in time, the electronic components inside the charger are easily damaged; another purpose is to solve the problem that the electronic components inside the charger are prone to generate high temperature when used for a long time, so as to achieve the effect of improving the cooling of the electronic components in the charger.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A mobile phone charger with a charging protection function comprises a charger body, a metal plug, a socket and a power conversion cavity, wherein the right side of the metal plug is fixedly connected to the left side of the charger body, the right side of the charger body is provided with a socket, the power conversion cavity is arranged on the inner wall of the charger body, and the left side of the power conversion cavity is electrically connected to the right side of the metal plug, a heat dissipation area is fixedly installed on the top of the charger body, a pushing device is arranged on one side of the socket, and one end of the pushing device is fixedly installed on the outer wall of the charger body.

[0008] A heat dispersion plate is fixedly mounted on the inner wall of the charger body, a heat conduction block and an angular guide block are fixedly mounted on the inner side wall of the heat dispersion plate, and the angular guide block is arranged above the heat conduction block, and the top of the heat dispersion plate overlaps the bottom of the heat dissipation area.

[0009] A further improvement of the technical solution of the present invention is that a sliding plate is slidably connected to the inner wall of the angular guide block, a contact plate is fixedly installed on the left side of the sliding plate, a power cavity is fixedly installed on the right side of the inner wall of the angular guide block, and a heat sensor is fixedly installed on the top of the power cavity.

[0010] The above technical solution is adopted, in which the heat sensor device is used as the switch of the power cavity. When the heat sensor device detects that the temperature reaches a peak value, the switch of the power cavity is opened.

[0011] A further improvement of the technical solution of the present invention is that a telescopic assembly is fixedly connected to the left side of the power chamber, a stop column is fixedly installed on the left side of the angular guide block, one side of the stop column overlaps the outer wall of the sliding plate, and an auxiliary pulley is fixedly installed on the outer wall of the sliding plate.

[0012] By adopting the above technical solution, the power chamber in the solution can provide power to the telescopic component, so that the telescopic component pushes the sliding plate to extend to one side.

[0013] A further improvement of the technical solution of the present invention is that: the inner wall of the pushing device is slidably connected with a force-bearing block, an elastic part is welded on the right side of the force-bearing block, a passive block is welded on the right side of the elastic part, the outer wall of the passive block is slidably connected with the inner wall of the pushing device, and the inner walls of the force-bearing block and the passive block are both provided with magnetic blocks.

[0014] By adopting the above technical solution, the magnetic blocks inside the force-bearing block and the passive block in the solution are in a repulsive state. In this way, when the force-bearing block moves, the passive block will also move under the influence of the magnetic force, thereby causing the passive block to move to one side of the pushing device, thereby automatically disconnecting the connecting line inserted into the surface of the socket.

[0015] A further improvement of the technical solution of the present invention is that a toothed contact strip is fixedly installed on the left side of the force-bearing block, a push plate is fixedly installed on the right side of the passive block, and the left side of the toothed contact strip is fixedly connected to the right side of the contact plate.

[0016] By adopting the above technical solution, the toothed contact strip in the solution is connected to the contact plate, so that when the sliding plate moves, the toothed contact strip cooperates to push the force bearing block to move.

[0017] A further improvement of the technical solution of the present invention is that a heat dissipation assembly is provided on one side of the angular guide block, the top of the heat dissipation assembly is fixedly connected to the bottom of the heat dispersion plate, a fitting frame is provided below the heat dissipation assembly, the outer wall of the fitting frame is fixedly connected to the inner wall of the heat dispersion plate, and the inner wall of the fitting frame is socketed with the outer wall of the power conversion chamber.

[0018] By adopting the above technical solution, the heat dissipation component in the solution can cool the bonding frame, thereby achieving the effect of cooling the surface of the power conversion cavity, avoiding the problem of high surface temperature of the power conversion cavity when powered for a long time.

[0019] A further improvement of the technical solution of the present invention is that through holes are provided on the outer walls of the fitting frame, and buffer devices are provided on both sides of the fitting frame, and one end of the buffer device is fixedly connected to one side of the fitting frame.

[0020] By adopting the above technical solution, the buffer device in the solution can play a buffering role between the bonding frame and the heat dispersion plate, thereby improving the stability of the power conversion cavity.

[0021] A further improvement of the technical solution of the present invention is that: the inner wall of the buffer device is slidably connected with an embedded block, the bottom of the embedded block is fixedly installed with a pressure plate, the bottom of the inner wall of the buffer device is fixedly installed with an extrusion airbag, and the top of the extrusion airbag overlaps the bottom of the pressure plate.

[0022] By adopting the above technical solution, the extrusion airbag in this solution has a certain elastic expansion force. When the embedded block moves inside the buffer device, its pressure plate will contact the extrusion airbag and trigger the extrusion airbag to generate a reaction force, thereby achieving a certain buffering effect when the embedded block moves inside the buffer device.

[0023] A further improvement of the technical solution of the present invention is that elastic pull belts are welded on both sides of the pressure plate, and an angular connector is welded on the right side of the elastic pull belt, the top of the angular connector is slidably connected to the bottom of the embedded block, and the right side of the angular connector is slidably connected to the inner wall of the buffer device.

[0024] By adopting the above technical solution, the angular connecting piece in the solution is more stable in order to facilitate the embedded block to move inside the buffer device.

[0025] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0026] 1. The present invention provides a mobile phone charger with charging protection function. The heat dissipation plate and the heat conductive block are used in combination. The heat emitted by the power conversion cavity can be transferred to the inside of the angular guide block through the heat conductive block. At the same time, with the assistance of the heat dissipation zone, the surface temperature of the heat dispersion can be dissipated outward in time, thereby reducing the excessive surface temperature of the charger body during long-term power supply, and avoiding the internal components being affected by the temperature and shortening their service life.

[0027] 2. The present invention provides a mobile phone charger with a charging protection function. Since a heat sensor device is arranged inside the angular guide block, the temperature of the surface of the heat conductive block can be monitored at all times. At the same time, the power cavity, the telescopic component and the sliding plate are matched. The power provided by the power cavity changes the state of the telescopic component, which can make the sliding plate extend outward, so that the contact plate thereon contacts with the pushing device, and the connector inserted in the socket is pushed outward by the pushing device. When the temperature inside the charger body reaches a peak value, the power cord can be automatically disconnected, thereby effectively protecting the electronic components inside the charger body from being affected by excessive temperature.

[0028] 3. The present invention provides a mobile phone charger with a charging protection function. The pushing device adopts the cooperation of a force-bearing block, a passive block and an elastic member. When the force-bearing block is pushed by the toothed contact strip, it will move toward the inside of the pushing device, so that the passive block extends outward in the pushing device. When the passive block moves, it drives the movement of the push plate, realizes the outward push of the line connector in the jack, realizes the electrical connection between the charger body and the connecting line, completely avoids the transmission of power supply, and effectively protects the internal structure of the power conversion cavity.

[0029] 4. The present invention provides a mobile phone charger with a charging protection function. The power conversion cavity can be buffered by the cooperation of a fitting frame and a buffer device arranged on the surface of the power conversion cavity, and the extrusion airbag arranged inside the buffer device has an elastic buffering force. When the buffer device is hit, the embedded block connected to the fitting frame will enter the buffer device and contact and squeeze the extrusion airbag, thereby triggering the gas buffering effect of the extrusion airbag. The force of the elastic airbag realizes the buffering between the fitting frame and the heat dispersion plate, thereby achieving the buffering between the power conversion cavity and the fitting frame.
