Description

Technical Field

[0002] As a convenient device for modern travel, car chargers are widely used in various motor vehicles to provide convenient charging services for mobile phones, tablets and other mobile devices. However, the heat dissipation problem encountered during use has always been one of the pain points of product design and use. Traditional car chargers often rely on active heat dissipation methods such as cooling fans to deal with the problem of heating, but this not only increases the manufacturing cost of the product, but also consumes extra electricity. At the same time, the work of the fan itself will also generate noise and increase the size of the equipment, which runs counter to the current trend of pursuing miniaturization, high efficiency and low noise. What's more serious is that under extreme conditions, such as long-term exposure to sunlight or excessive temperature inside the vehicle, the car charger may cause performance degradation and shortened life due to overheating, and even cause safety hazards, such as explosion or vehicle circuit short circuit, posing a threat to user safety.

[0008] A preferred technical solution: a screw hole is provided on the upper surface of the mounting platform, and the hole depth of the screw hole is smaller than the height of the mounting platform.

[0009] A preferred technical solution: the cathode contact is a cathode spring sheet in a U shape, and two contact points are respectively fixed at the front ends of both sides of the cathode spring sheet.

[0010] A preferred technical solution: the charging interface is exposed outside the shell, a warning light is arranged on the top of the shell, and the warning light is electrically connected to the circuit board.

[0011] The beneficial effect compared with the prior art is that, by adopting the above scheme, the utility model arranges a cooling tube inside the shell and injects coolant into the cooling tube, thereby reducing the probability of accidents caused by high temperature; similarly, the circuit board will not trigger the circuit current limiting module due to excessive temperature, thereby affecting the user's charging experience; three mounting platforms are arranged in the installation area to stabilize the circuit board inside the shell; the number of mounting holes on the disassembly plate is consistent with the number of mounting platforms, and the mounting holes and the screw holes of the mounting platform are on the same vertical plane; screws or screws are used to penetrate the sealing plate and the circuit board in sequence and fix them in the screw holes on the mounting platform, thereby simplifying the structure and facilitating disassembly and maintenance.

[0017] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "fixed", "integrally formed", "left", "right" and similar expressions used in this specification are for illustrative purposes only. In the drawings, units with similar structures are marked with the same reference numerals.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by technicians in the technical field of the utility model.
