Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a vehicle-mounted charger with an auxiliary window-breaking function. Background Art

[0002] With the increasing popularity of automobiles, the frequency of use of on-board chargers as important accessories inside cars is also increasing. The main function of traditional on-board chargers is to provide power output to meet the user's demand for charging electronic devices during driving. However, in emergency situations, such as dangerous scenes such as vehicles being trapped and windows unable to open, traditional on-board chargers cannot provide additional auxiliary functions, which makes it difficult for passengers to save themselves or wait for rescue. In recent years, with the improvement of people's awareness of driving safety, the functional requirements for on-board chargers have gradually diversified. In addition to the basic charging function, users also expect on-board chargers to have some auxiliary functions in emergency situations, such as window breaking functions, so that they can quickly break windows and escape in emergency situations. However, most of the on-board chargers on the market currently only have a single charging function and lack auxiliary functions in emergency situations. Although some products try to combine the window breaking function with the on-board charger, there are often problems such as complex structure, inconvenient operation, and poor window breaking effect, which cannot meet the actual needs of users. Therefore, the development of a car charger that has both a charging function and an auxiliary window breaking function in an emergency has become an urgent problem to be solved in the current field of on-board charger technology. Utility Model Content

[0003] The purpose of the utility model is to overcome the problems existing in the prior art and provide a vehicle charger with an auxiliary window breaking function. The window breaking component can assist in breaking windows in dangerous situations without affecting the normal use of the vehicle charger.

[0004] The utility model is realized through the following technical scheme: a vehicle charger with auxiliary window breaking function, comprising a charger shell, one end of the charger shell is provided with a USB charging connector, the other end of the charger shell is provided with a window breaking assembly, a circuit board electrically connected to the USB charging connector is provided in the charger shell, the circuit board is electrically connected to an electrode assembly, the electrode assembly includes a negative electrode spring movably embedded in the charger shell, the window breaking assembly includes a hammer head seat provided on the charger shell, an alloy window breaking column is provided on the hammer head seat, the alloy window breaking column is movably provided in the charger shell, wherein an inner end of the alloy window breaking column is connected to the circuit board, an outer end of the alloy window breaking column penetrates the charger shell and is provided with a hard alloy head, and a blocking mechanism is provided in the charger shell corresponding to an inner end of the alloy window breaking column to prevent the alloy window breaking column from retracting.

[0005] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0006] Preferably, an arched gripping portion is provided at one end of the charger housing away from the window breaking assembly.

[0007] Preferably, anti-slip grooves are circumferentially arranged on the outer wall of the gripping portion.

[0008] Preferably, the charger housing is a hard metal part, and two negative electrode springs are symmetrically arranged, and the outer sides of the negative electrode springs protrude from the charger housing.

[0009] Preferably, an insulating connection seat is provided between the charger housing and the hammer head seat, and the insulating connection seat is threadedly connected to one end of the charger housing.

[0010] Preferably, there are multiple USB charging connectors, and a dust cover is provided at one end of the charger housing corresponding to the position of the USB charging connector.

[0011] Preferably, the blocking mechanism includes a blocking iron gasket arranged on the inner wall of the charger shell, the blocking iron gasket is fan-shaped and two are symmetrically arranged around the center, a receiving groove is opened on the inner wall of the charger shell corresponding to the position of the blocking iron gasket, one end of the blocking iron gasket is hinged on the charger shell through a rotating shaft, and a check spring is arranged in the receiving groove corresponding to the position of the blocking iron gasket, and the check spring is used to bend the free end of the blocking iron gasket toward the position of the alloy broken window column.

[0012] The beneficial effects of the utility model are mainly reflected in the following aspects:

[0013] 1. First, by integrating the window-breaking component into the car charger, the charger functions are diversified. In an emergency, users can use the window-breaking component to quickly break the window and escape, which improves driving safety. At the same time, this design also avoids the trouble of carrying additional window-breaking tools, making the car charger more practical and convenient.

[0014] 2. In emergency situations, such as when the vehicle is trapped or the window cannot be opened, the on-board charger can quickly play the window breaking function to help passengers escape quickly. The carbide head design of the alloy window breaking column makes the window breaking operation more efficient and convenient, greatly improving the rescue efficiency. Secondly, the electrical connection between the circuit board and the electrode assembly, as well as the ingenious design of the blocking mechanism, ensure the safety of the window breaking assembly during normal use. When the window is not needed, the alloy window breaking column is effectively fixed by the blocking mechanism to prevent misoperation or accidental triggering. At the same time, the fan-shaped design of the blocking iron gasket and the use of the non-return spring enable the blocking mechanism to quickly pop out the blocking iron gasket when the window needs to be broken, preventing the alloy window breaking column from retracting during the window breaking process, and can rigidly support the bottom of the alloy window breaking column, ensuring the reliability of the window breaking function. In addition, the on-board charger also has a USB charging connector, which can meet the daily charging needs of passengers and realize the diversification of functions. This design not only improves the practicality of the product, but also reduces the burden of passengers carrying multiple devices in the car. In summary, the utility model of a car charger with auxiliary window breaking function has an auxiliary window breaking function while maintaining the charging function, thereby improving the safety and practicality of the product. Its innovative design and ingenious mechanism setting enable the car charger to play an important role in emergency situations and provide strong protection for the safety of passengers.
