Detailed Description

It is easily understood that according to the technical solution of the present invention, a person skilled in the art can propose various alternative structures and implementation ways without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

In the following description, various parameters and components are described for different configurations of embodiments, and these specific parameters and components are only by way of example and do not limit the embodiments of the present application.

An embodiment according to the invention is illustrated with reference to fig. 1, in which it can be seen that: the car mouthful structure of charging includes: a mouth pipe 1 fixedly connected with a vehicle body; a port cover 2 movable relative to the port pipe 1 to open or close the charging port; a hinge 3, such as a rotary hinge, one end of the hinge 3 is fixedly connected with the mouth cover 2, and the other end of the hinge 3 is fixedly connected with the mouth pipe 1; and a heater 4 provided at one or more of the mouth pipe 1, the flap 2, and the hinge 3. Through the heater that sets up in the car mouthful structure that charges, can charge mouthful structure to the car and heat the ice-breaking when freezing in the mouth that charges to be favorable to opening smoothly of the mouth that charges, user experience is good, convenient to use.

The heater 4 is preferably disposed around the hinge 3 or the heater 4 is disposed around the junction of the flap 2 and the spout 1. The joint of the cover 2 and the mouth pipe 1 is a joint of the cover 2 and the mouth pipe 1 when the charging port is closed, for example, an edge of the cover 2. In cold weather, water, rain, snow, or the like easily seeps into the gap between the moving parts of the hinge 3 or the gap at the joint of the flap 2 and the spout 1, thereby causing the flap 2 not to be smoothly opened. By means of the above-described arrangement of the heater 4, the charging port structure can be heated in a targeted manner.

The charging port structure includes a temperature sensor for detecting a temperature at the charging port, and controls heating (e.g., on or off) of the heater 4 according to the detected temperature. The temperature sensor can be arranged at the charging port independently and used for detecting the ambient temperature around the charging port. Of course, the temperature sensor may also be an existing temperature sensor on the vehicle (e.g., a temperature sensor for detecting the ambient temperature), which may eliminate a separate temperature sensor at the charging opening.

When the car mouth structure of charging is the electric switch formula, the car mouth structure of charging can include motor 5, and it can drive flap 2 is relative the mouth pipe 1 motion. The charging port structure may further include a current sensor for detecting a current flowing through the motor 5 and controlling heating (e.g., turning on or off) of the heater 4 according to the detected current.

The charging port structure may include a control module for controlling heating of the heater 4. The control module is for example provided as a separate component, or the control module may be integrated in the BCM. To the car condition that the mouthful structure that charges is electric switch formula, after the mouth that charges is frozen in the bad weather of low temperature, if the starter motor 5 opens the mouth that charges, then motor 5 will be locked up commentaries on classics. Logic may be provided to automatically activate the heating function of the heater 4 by determining that the outdoor temperature is lower than a predetermined temperature value (e.g., the outdoor temperature is below zero degrees celsius) and the current flowing through the motor 5 is a locked-rotor current, so as to prevent false triggering of the heating function in low-temperature weather or when the motor 5 is locked-rotor by other reasons. Logic may be provided to turn off the heating function of the heater 4 that the current (e.g., 1 to 2 amps) flowing through the motor 5 is much less than the stall current (e.g., 5 to 10 amps), i.e., the motor 5 is in a normal operating state. Of course, the heating function may also be arranged to be triggered by a physical button or a software button, i.e. manually. The above functions can be realized by the relevant setting of the control module. The locked-rotor current is a current flowing through the motor when the motor is normally energized but cannot be operated due to icing or external force.

The charging port structure may further include a fuse connected in series with the heater 4, and the fuse plays a role of protecting a circuit when a current is too large in a circuit of the heater 4, thereby preventing the heater 4 from being overheated or burning other components.

The heater 4 is a device for heating, for example, a national standard resistance wire can be selected, and the material of the resistance wire is selected from one or more of silver, tungsten, iron chromium aluminum and nickel chromium. The resistance wire has certain resistivity, and can generate heat after being electrified. By accurate design and calculation, the resistance wire with the selected specification can emit heat in a short time so as to melt the ice layer and simultaneously not damage or ignite the materials near the charging port.

The heater 4 may be embedded in the mouth tube 1, the flap 2 or the hinge 3 by two-shot molding. This process of incorporating the heater 4 is particularly advantageous when the spout 1, the flap 2 or the hinge 3 is a plastic part. By "two-shot" is meant the following process (taking the heater 4 in the mouthpiece 1 as an example): the half nozzle is first injection molded, then the heater 4 is placed on the injection molded half nozzle, and finally the injection molding of the other half nozzle is completed.

As shown with reference to fig. 2, the heater 4 is advantageously arranged inside the flap 2. Of course, the heater 4 can also be arranged inside the mouth piece 1 or the hinge 3. In this way, the danger of scalding and electric shock to people when the heater 4 is exposed outside is prevented.

The present invention also includes a vehicle having the vehicle charging port structure according to any one or more of the embodiments described above, wherein the technical features and technical effects thereof are similar to those described above, and thus will not be described herein again.

The invention also comprises a method for controlling the structure of the charging port of the automobile. The method specifically comprises the following steps: if the port cover cannot move relative to the port pipe due to freezing, the heating function of the heater is activated. After the heating function of the heater is activated, if the port cover can move relative to the port pipe, the heating function of the heater is turned off. The method can be automatically realized through a control module in the automobile charging port structure, and can also be realized through manually triggering a physical button or a software button. Further, the method can be applied to the case where the flap is opened manually or the flap is opened automatically.

By the method, the charging port structure of the automobile can be heated and iced when the charging port is iced, so that the charging port can be smoothly opened, and the automobile charging port structure is good in user experience and convenient to use.

For the situation that the opening cover is automatically opened by the motor, the method can also comprise the following steps: if the outdoor temperature is lower than the set temperature value and the current flowing through the motor is the locked-rotor current, starting the heating function of the heater; after the heating function of the heater is started, if the current flowing through the motor is less than the locked-rotor current, the heating function of the heater is closed.

The technical scope of the present invention is not limited to the above description, and those skilled in the art can make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and such changes and modifications should fall within the protective scope of the present invention.
