Abstract
The utility model discloses a charging interface heat-shielding device for an electromobile, relating to a charging port of an electromobile. The charging interface heat-shielding device is characterized in that a temperature detection probe and a control module are matched to ensure that the temperature of the charging interface cannot exceed the temperature specified in the national standard when the electromobile is charged, so that charging equipment is prevented from being burnt down, charging safety of the electromobile is facilitated, and sudden accidents caused by fire hazard and the like because the charging equipment is burnt down caused by circuit short-circuiting due to heating of metal contacts are prevented. The charging interface heat-shielding device is simple in structure, stable and reliable in performance, convenient to use and safe and energy-saving.
Description
Technical field
The utility model relates to the charging electric vehicle interface, particularly a kind of charging electric vehicle interface thermal protection.
Background technology
Since China's reform and opening-up, national economy increases fast, and " scientific and technical innovation, autonomous innovation " become the main flow of current industrial development, and China's industry progressively develops to the direction of intensive style, energy-saving and emission-reduction, low-carbon (LC).The power vehicle consumes energy, discharging tail gas, pollutant atmosphere; For environmental protection, developed country's great majority develop to the electric automobile direction in the world, and China is at the early-stage.The charging electric vehicle time is long, and charging current is big during charging.If charging inlet can not contact well, then just heating easily between plug and the socket, when such work for a long time, the lighter can make the metal contact heating, and weight person can make short circuit, thereby burns charging device, causes fire.In order to address this problem; R&D institution and science and technology in enterprise personnel are constantly studying, are exploring; Utilize modern science and technology; The traditional electric automobile charging inlet is improved and innovates, and some are progressive though obtained technically, in practice, still exist the technical barrier that does not overcome as yet.
Summary of the invention
The purpose of the utility model is to overcome above deficiency, and a kind of charging electric vehicle interface thermal protection is provided, and through temperature detection probe and the general charging inlet metal contact close installation of heating easily, and carries out the isolation on electric with the imines film.During charging electric vehicle, if the socket and plug loose contact, the charging inlet temperature can rise, and surpasses the temperature of stipulating in the national standard, and can give the alarm automatically, and reduce charging current, thereby avoid accident to take place, and safe, energy-conservation, long service life.
The utility model solves the technical scheme that its technical problem adopted: contain general charging inlet, charging connection affirmation metal contact, ground wire metal contact, control and confirm metal contact, zero line metal contact, control module, voltage comparator circuit, Single-chip Controlling warning circuit, charger control circuit, subsequent use metal contact, temperature detection probe, live wire metal contact; General charging inlet shell is an apple shape; A row is provided with to charge with connecting and confirms metal contact and control affirmation metal contact above in the general charging inlet; The centre is provided with three metal contact; Be respectively live wire metal contact, ground wire metal contact, zero line metal contact; Respectively be provided with a temperature detection probe below live wire metal contact and the zero line metal contact; In the middle of two temperature detection probes, be provided with two subsequent use metal contact,, formed a kind of charging electric vehicle interface thermal protection by control module and the charger control circuit that voltage comparator circuit, Single-chip Controlling warning circuit are formed altogether.
The know-why that the utility model adopts is: during charging electric vehicle, and live wire metal contact, the loose contact of zero line metal contact in the charging inlet, live wire metal contact, zero line metal contact can be generated heat; When temperature detection probe detects temperature and surpasses the temperature of stipulating in the national standard; Send signal, pass to the voltage comparator circuit in the control module through lead, voltage comparator circuit passes to the Single-chip Controlling warning circuit again; Give the alarm; And transmit a signal to the charger control circuit, and reduce charging current, live wire metal contact in the charging inlet, zero line metal contact temperature are no longer risen.Prevent to burn electric equipment, cause burst accidents such as fire, prolong charging device useful life, avoid fire incident, energy-saving safe owing to the too high short circuit that causes of metal contact temperature.
The utility model beneficial effect is: this device is through cooperating between temperature detection probe and the control module; The charging inlet temperature can not surpass the temperature of stipulating in the national standard when making charging electric vehicle; Avoid charging device to burn; Help the fail safe of charging electric vehicle, thereby prevent owing to the metal contact heating causes that short circuit burns charging device, causes burst accidents such as fire.It is simple in structure, stable and reliable for performance, and is easy to use, energy-saving safe.
Description of drawings
Be to combine accompanying drawing and embodiment that the utility model is further described below:
Fig. 1 is a charging electric vehicle interface thermal protection structural representation.
In the drawings: 1 general charging inlet, 2 chargings connect confirms metal contact, 3 ground wire metal contact, 4 control affirmation metal contact, 5 zero line metal contact, 6 control modules, 7 voltage comparator circuits, 8 Single-chip Controlling warning circuits, 9 charger control circuits, 10 subsequent use metal contact, 11 temperature detection probe, 12 live wire metal contact.
Embodiment
In Fig. 1; A row is provided with to charge with connecting and confirms metal contact 2 and control affirmation metal contact 4 above in the general charging inlet 1 of charging electric vehicle interface thermal protection; A middle row is provided with three metal contact; From left to right be respectively live wire metal contact 12, ground wire metal contact 3, zero line metal contact 5, be respectively equipped with two temperature detection probes 11 below live wire metal contact 12 and the zero line metal contact 5, in the middle of temperature detection probe 11, be provided with two subsequent use metal contact 10; By control module 6 and the charger control circuit 9 that voltage comparator circuit 7, Single-chip Controlling warning circuit 8 are formed altogether, formed a kind of charging electric vehicle interface thermal protection.
This charging electric vehicle interface thermal protection is when charging electric vehicle, if the loose contact of charging inlet metal contact, live wire metal contact 12 can be generated heat with zero line metal contact 5; When temperature detection probe 11 detects temperature and surpasses the temperature of stipulating in the national standard; Send signal, pass to the voltage comparator circuit 7 in the control module 6 through lead, voltage comparator circuit 7 passes to Single-chip Controlling warning circuit 8 again; Give the alarm; And transmit a signal to charger control circuit 9, and reduce charging current, live wire metal contact 12 in the charging inlet, zero line metal contact 5 temperature are no longer risen.Prevent to burn electric equipment, cause burst accidents such as fire, prolong charging device useful life, avoid fire incident, energy-saving safe owing to the too high short circuit that causes of metal contact temperature.
