Description

  The present invention relates to a snow icing prevention device in a fender mounted on a vehicle.

  In a vehicle used in a cold region, a stainless steel plate may be attached to a vertical rear wall surface of a fender which is a frame portion constituting a tire house. The stainless steel plate eliminates the unevenness on the vertical wall surface behind the fender, and even if it snows (is icing or icing) on the stainless steel plate attached to the vertical wall on the rear side of the tire, This is to make it easier to drop.

  For example, Patent Document 1 describes a vehicle fender liner configured to exhibit sound absorption performance and anti-icing property.

And a heater operating means for operating the heater 11 when the outside air temperature detected by the outside air temperature detecting means is equal to or lower than a threshold value.

  The fender 2 of the vehicle 1 is constructed between joists (not shown) opposed to each other with tires (front wheels, rear wheels) 3 interposed therebetween, and is mainly composed of an arch-like member 4 and a side wall portion 5. The lower part of the arch-shaped member 4 forms a tire front vertical wall surface 6 positioned in the vehicle front direction with respect to the tire 3 and a tire rear vertical wall surface 7 positioned in the vehicle rear direction with respect to the tire 3.

  In the snow icing prevention device 10A in the fender according to the first embodiment, the heater 11 is attached to the tire rear vertical wall surface 7 of the fender 2, and the heater 11 is powered by an electric circuit 12 (vehicle battery). 13 is connected. The heater 11 is configured by, for example, an electric heating mat (electric heating mat with a heating wire) in which a heating wire is covered with silicon rubber.

  Further, a heat transfer plate 14 is attached to the tire rear vertical wall surface 7 of the fender 2 so as to cover the heater 11, so that the heat radiation area of the heater 11 is expanded. The heat transfer plate 14 is made of a plate material about one size larger than the heater (electric heating mat) 11 and has a function of preventing damage to the heater 11 due to chipping (pushing by a rod, pipe, or the like). The heat transfer plate 14 is made of, for example, a stainless plate.

  The heat transfer plate 14 is disposed so as to cover almost the entire surface of the tire rear vertical wall surface 7 except for the lower end portion where the mud flap 8 is attached to the tire rear vertical wall surface 7 of the fender 2. The heat transfer plate 14 is fixed to the tire rear vertical wall surface 7 of the fender 2 with screws (small screws) at a portion where the heaters 11 are not provided.

  A sealing material 16 is sandwiched between the heat transfer plate 14 and the tire rear vertical wall surface 7 as a rust prevention measure for the tire rear vertical wall surface 7 (joist) of the fender 2. Moreover, in order to make it easy to come out even if water enters between the heat transfer plate 14 and the tire rear vertical wall surface 7 of the fender 2, the sealing material 16 is disposed almost entirely on the upper edge of the heat transfer plate 14. However, the sealing material 16 is disposed from the vicinity of the upper end edge to the position of about half of the height in the vertical direction at the left and right side edges of the heat transfer plate 14 (see FIG. 2).

  Further, the vehicle 1 is provided with an outside air temperature detection thermostat 17 that detects the outside air temperature, and a main switch 18 of the fender internal snow icing prevention device 10A. The outside air temperature detection thermostat 17 is turned on when the outside air temperature becomes a threshold value (0 ° C. in the present embodiment) or less, and is interposed in the electric circuit 12 between the heater 11 and the power source 13. The outside air temperature detecting thermostat 17 constitutes outside air temperature detecting means and heater operating means of the present invention. The main switch 18 is switched on and off by a driver in the driver's seat and is electrically connected to the electric circuit 12.

As a result, the temperature of the tire rear vertical wall surface 7 of the fender 2 is maintained at 0 ° C. or more, which is the solidification temperature of water. On the other hand, when all of the above conditions (1) to (3) are not met, the heater 11 is not energized.

  Causes of snow accretion on the tire rear vertical wall surface 7 of the fender 2 are that moisture (liquid) attached to the tire rear vertical wall surface 7 changes to ice (solid) in a temperature environment of 0 ° C. or less, It is conceivable that the water rolled up by the tire 3 is bonded (fixed) to the ice.
