Patent Application
20200406725
This application claims priority to Japanese Patent Application No. 2019-121595 filed on Jun. 28, 2019, which is incorporated herein by reference in its entirety including the specification, claims, drawings, and abstract.
The present disclosure relates to a vehicle having a front windshield or a rear windshield divided into upper and lower portions.
JP 2017-214059 A discloses a front windshield having a laminated glass structure in which a resin interlayer film is bonded between an outer glass plate and an inner glass plate.
Because the resin interlayer film is bonded between the outer glass plate and the inner glass plate in the front windshield described in JP 2017-214059 A, should an object collide with the windshield, fragments of broken glass will not scatter, the impact is absorbed by the interlayer film, and the colliding object cannot easily pass through the windshield. However, such a structure that makes penetration completely through the windshield difficult may make it difficult for a person to escape from the vehicle should the vehicle rolls over and the doors on the side of the vehicle are blocked.
It is therefore an object of the present disclosure to provide a vehicle that allows a person to escape from the vehicle when the vehicle rolls over, and a door provided on a side of the vehicle be blocked.
A vehicle according to the present disclosure includes a partition member that divides a front or rear windshield into an upper windshield and a lower windshield, with the fragility of the upper windshield differing from the fragility of the lower windshield.
Since either one of the upper windshield and the lower windshield divided by the partition member is fragile, when the vehicle rolls over, and a doorway provided on a side of the vehicle is blocked accordingly, a person can escape from the vehicle by breaking the fragile windshield.
According to an aspect of the vehicle of the present disclosure, the upper windshield may be more fragile than the lower windshield.
According to this aspect, when the vehicle rolls over, and the door provided on the side of the vehicle is blocked, a person can escape from the vehicle by breaking the upper windshield.
According an aspect of the vehicle of the present disclosure, the upper windshield may be sufficiently fragile as to be breakable by human effort and have a width in an upward and downward direction larger than the diameter of a human head.
According to this aspect, when the vehicle rolls over, and the doorway provided on the side of the vehicle is blocked, a person can escape from the vehicle by breaking the upper windshield using unassisted strength.
According to an aspect of the vehicle of the present disclosure, the upper windshield may be made of glass, and the lower windshield may be made of polycarbonate or have a laminated glass structure.
According to this aspect, the lower windshield is made of polycarbonate or has a laminated glass structure to make an object hard to pass through the lower windshield, and the upper windshield is made of glass to allow a person to escape from the vehicle by breaking the upper windshield.
According to an aspect of the vehicle of the present disclosure, the vehicle may have a door provided only on one side of the vehicle.
According to this aspect, a person can escape from the vehicle by breaking the upper windshield even when the vehicle rolls over such that the side on which the door is provided faces downward.
According to an aspect of the vehicle of the present disclosure, the upper windshield is higher in light transmittance than the lower windshield.
According to this aspect, because the upper windshield is higher in light transmittance than the lower windshield, light can enter the vehicle from above, which enables increasing a sense of spaciousness for occupants of the vehicle.
According to the present disclosure, it is possible to provide a vehicle that allows a person to escape when the vehicle rolls over in such a manner that the doorway provided on the side of the vehicle is blocked.
Embodiments of the present disclosure will be described based on the following figures, wherein:
A vehicle 10 according to an embodiment will be described below with reference to the figures. An arrow FR, an arrow UP, and an arrow RH shown in each of the figures to be described below indicate a forward direction (travel direction), an upward direction, and a rightward direction of the vehicle, respectively. Further, a direction opposite to the arrow FR, a direction opposite to the arrow UP, and a direction opposite to the arrow RH indicate a rearward direction, a downward direction, and a leftward direction of the vehicle, respectively. Hereinafter, when a description is given simply using a frontward and rearward direction, a leftward and rightward direction, or an upward and downward direction, unless otherwise specified, the frontward and rearward direction, the leftward and rightward direction, and the upward and downward direction indicate front and rear in the frontward and rearward direction of the vehicle, left and right in the leftward and rightward direction of the vehicle (vehicle width direction), and top and bottom in the upward and downward direction of the vehicle, respectively.
As shown in
The lower windshield 12 is made of polycarbonate and has enough strength so as to prevent a flying object such as a stone from breaking or passing through the lower windshield 12 when the flying object collides with the lower windshield 12. Therefore, even when the vehicle 10 rolls over, and the door 2 is blocked accordingly, it is difficult to break the lower windshield 12 to make a hole large enough for a person to pass through.
The lower windshield 12 may have, instead of the structure made of polycarbonate, a laminated glass structure in which a resin interlayer film is bonded between an outer glass plate and an inner glass plate. Even when an object such as a stone collides with the lower windshield 12 having the laminated glass structure, fragments of broken glass are not scattered, the impact is absorbed by the interlayer film, and the colliding object is hard to pass through the windshield. Therefore, should the vehicle 10 roll over in such a manner that the door 2 is blocked accordingly, it is difficult to make a hole in the lower windshield 12 large enough for a person to pass through.
The upper windshield 11 is made of glass and is sufficiently fragile as to be breakable by human power. That is, the upper windshield 11 is more fragile than the lower windshield 12. A width in the upward and downward direction of the upper windshield 11 is larger than a diameter of a human head. Therefore, even when the vehicle 10 rolls over with the left side facing downward in such a manner that the door 2 is blocked accordingly, a person can escape from the vehicle 10 by breaking the upper windshield 11 with their own power.
As described above, in the vehicle 10 according to the present embodiment, the windshield 1 is divided into upper and lower portions by the division bar 3, the lower windshield 12 is made of polycarbonate or has a laminated glass structure to make an object hard to pass through the lower windshield 12, and the upper windshield 11 is made of glass to allow a person to escape from the vehicle by breaking the upper windshield 11.
Should the vehicle 10 rolls over, the possibility that the front or rear side faces downward is very small as compared to the possibility that the vehicle 10 rolls over with the left or right side facing downward, or the possibility that the vehicle 10 is inverted with the top side facing downward. Therefore, in order to allow a person to escape from the front side of the vehicle 10 even when the left or right side is blocked or the top side is blocked, the vehicle 10 has the upper windshield 11 made of glass that can be broken by human power.
The upper windshield 11 is higher in light transmittance than the lower windshield 12. This allows light to enter the vehicle 10 from above the vehicle 10, thus making it possible to increase a sense of spaciousness for occupants of the vehicle.
The vehicle of the present disclosure is not limited to the above-described embodiment and may be implemented according to various embodiments within the scope of the present disclosure. For example, the division bar may be provided on the rear windshield, and the rear windshield may be divided into an upper windshield and a lower windshield.
