Detailed Description
The following detailed description will be made with reference to the accompanying drawings and examples, so that how to implement the technical means of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.
Referring to fig. 1, fig. 1 is a schematic view of a rail transit window glass capable of being forcibly heated manually according to an embodiment of the present invention.
As shown, a manually forcibly heatable rail transit glazing comprises: a pane 1 and an external circuit 2, wherein the external circuit 2 consists of a heating circuit and a control circuit. The heating circuit comprises a heating element 4, a first electrical connector 6, and a heating power source connected in series, wherein the heating element 4 is mounted to the glazing 1; the control loop is connected with the heating loop through a contactor 8 and comprises a temperature controller, a second electric connector 5, a multi-gear switch 7 and a control power supply, wherein the temperature controller is arranged on the window glass 1; the multi-gear switch 7 is provided with an automatic heating position a and a manual forced heating position b, the automatic heating position a is connected with the second electric connector 5 and the temperature controller in series, and forms an automatic control loop with the control power supply; the manual forced heating position b is connected in series with a control power supply to form a manual control loop.
The utility model discloses manual forced heating function has been increased. Namely, under the normal condition, the glass starts the automatic temperature control mode, and the heating on-off can be automatically controlled according to the glass temperature. Under the automatic temperature control mode, if the glass is fogged and the glass can not be heated, the manual forced heating mode can be switched to, so that the function of heating the glass in time under other conditions such as fogging and the like is realized, and the driving safety is guaranteed.
It should be understood that the temperature controller of the utility model has the temperature control switch 3, and the temperature controller is conveniently opened and disconnected to complete the work. The contactor 8 includes a coil and a normally open contact, and functions of electrically connecting the two loops are realized.
The multi-gear switch 7 is also provided with a stop position, and the stop position disconnects the control power supply, namely, the heating circuit is also closed, so that the whole circuit is conveniently closed, and the heating work is stopped.
The heating power supply and the control power supply are set to be direct current or alternating current, and various voltages can be selected according to actual application requirements.
In one embodiment of the present invention, the lower temperature point of the temperature controlled switch 3 is assumed to be 15 ℃, and the upper temperature point is assumed to be 27 ℃. (the interior of the temperature control switch is automatically switched on when the temperature is lower than 15 ℃ and is automatically switched off when the temperature is higher than 27 ℃).
As shown in fig. 1, when the multi-position switch 7 is in the stop position, the control circuit is in the off mode, and the heating circuit is also in the off mode.
Assuming that the ambient temperature is now 10 ℃ (15 ℃ below the lower temperature point), the temperature control switch 3 is automatically turned on. At this moment, dial many grades of switches 7 to automatic heating position a, then control power, second electric connector 5, temperature detect switch 3, contactor 8 intercommunication, control power switch-on promptly, contactor 8's coil gets electricity to = contactor 8's normally open contact closure, heating circuit switch-on, glass begin to heat the defrosting defogging. When the temperature of the glass rises to 27 ℃ (the temperature reaches the upper temperature point of 27 ℃), the temperature control switch 3 is disconnected, so that the control loop is disconnected, the coil of the contactor 8 is powered off, the normally open contact is reset, the heating loop is disconnected, and the glass stops heating.
Now, assuming that the ambient temperature is 20 ℃ (15 ℃ higher than the lower temperature point), the glass is fogged, and the inside of the temperature controlled switch 3 is in an off state. When the multi-gear switch 7 is shifted to the automatic heating position a, the control loop is also in an off state because the temperature control switch 3 is in an off state, and the heating loop is also in an off state, so that the glass cannot be heated.
When the environment temperature is 20 ℃, the multi-gear switch 7 can be shifted to the manual forced heating position b without passing through the temperature control switch 3, so that the control power supply, the multi-gear switch 7 and the coil of the contactor 8 directly form a control loop. The coil of the contactor 8 is electrified, the normally open contact of the contactor 8 is closed, the heating loop is connected, and the glass starts to be heated. In order to avoid the adverse effect on the service life of the glass caused by long-time heating.
The manual forced heating position b of the delay switch 7 can be provided with a delay function, namely, a power-off delay timer is arranged at the manual forced heating position b and is used for delaying and disconnecting the manual forced heating position. For example, after the circuit is switched on for 30 minutes, the circuit jumps to an automatic heating position a or a stop position, so that the safety and the practicability of the circuit are ensured.
It is worth mentioning that, the utility model discloses a first electric connector 6 and second electric connector 5 are all installed outside window glass 1, avoid exposing at window glass 1 and influence the outward appearance, and heating power supply and control power supply all install at the automobile body, by unit control.
