JP6791069B2 - Outside air introduction structure for ultra-compact mobility - Google Patents

Description

The present invention relates to an outside air introduction structure for ultra-compact mobility that introduces outside air into an indoor space.

In recent years, a vehicle called ultra-compact mobility, which has a passenger capacity of two or less, has been developed. This ultra-compact mobility may not be equipped with an air conditioner, which is an electric air conditioner, in order to reduce the weight of the vehicle body, even if the interior space is substantially sealed, and the outside air is taken into the interior space. It may not have a structure to be introduced in.

In this case, especially in summer, even if the temperature of the indoor space (hereinafter referred to as "indoor temperature") rises to a temperature at which the driver feels uncomfortable, there is no means for positively lowering the indoor temperature. Further, especially in winter, there is also a means for positively suppressing the fogging of the window glass due to the difference between the indoor temperature and the outside air temperature, and for positively eliminating the fogging when the window glass becomes cloudy. Absent.

Therefore, in ultra-compact mobility having a substantially enclosed indoor space, outside air can be introduced into the indoor space in order to lower the indoor temperature, suppress fogging of the window glass, or eliminate fogging of the window glass. It is hoped that it has become.

As an outside air introduction structure for introducing outside air into the interior space, a structure for introducing outside air into the interior space from an outside air intake port provided in the hood of the vehicle is known (see, for example, Patent Document 1).

Ultra-compact mobility often does not have parts like the hood of a conventional vehicle. Therefore, in ultra-compact mobility, the space for providing the outside air introduction structure is limited. Therefore, even if an attempt is made to provide an outside air introduction structure for a vehicle equipped with a bonnet in ultra-small mobility, there is a possibility that such an outside air introduction structure cannot be provided.

The present invention has been made to address the above-mentioned problems. That is, one of the objects of the present invention is to provide an ultra-compact mobility outside air introduction structure capable of introducing outside air into an indoor space.

The outside air introduction structure (40L, 40R) according to the present invention is applied to the ultra-small mobility (10). The ultra-compact mobility includes a body (11) and side mirrors (20L, 20R). The side mirrors include a stay portion (21L, 21R) attached to the front side portion of the body, a stem portion (22L, 22R) extending upward from the stay portion, and a head portion attached to the upper part of the stem portion. (23L, 23R) is provided.

The outside air introduction structure according to the present invention introduces outside air into the indoor space (19) of the ultra-compact mobility. The outside air introduction structure according to the present invention includes an outside air intake port (41L, 41R) that opens on the front wall surface of the stay portion, an outside air discharge port (42L, 42R) that opens in the front region of the indoor space, and the above. A duct (43L, 43R) for connecting the outside air intake port and the outside air discharge port is provided.

According to the outside air introduction structure according to the present invention, the outside air taken into the duct from the outside air intake port can be introduced into the indoor space from the outside air discharge port. The outside air intake port is provided in the stay portion of the side mirror. Therefore, even when the space for providing the outside air introduction structure is limited as in the case of ultra-compact mobility, the outside air introduction structure can be provided.

<Outside air introduction structure>
As shown in FIG. 3, the implementation structure includes a left side outside air introduction structure portion 40L and a right side outside air introduction structure portion 40R. Hereinafter, the left side outside air introduction structure portion 40L is referred to as “left side structure portion 40L”, and the right side outside air introduction structure portion 40R is referred to as “right side structure portion 40R”.

<Left structural part>
The left side structural portion 40L includes an outside air intake port 41L, an outside air discharge port 42L, a duct 43L, and a register 46L.

The outside air intake port 41L is provided so as to open forward on the front wall surface of the stay portion 21L of the left side mirror 20L. The outside air discharge port 42L is provided on the outer wall surface of the left side trim 11Ld exposed in the indoor space 19. One opening 43La of the duct 43L is connected to the outside air intake port 41L, and the other opening 43Lb of the duct 43L is connected to the outside air discharge port 42L. Therefore, the duct 43L connects the outside air intake port 41L and the outside air discharge port 42L.

The register 46L is arranged at the outside air discharge port 42L. The register 46L is used by the driver to adjust the flow rate and flow direction of the outside air discharged from the outside air discharge port 42L into the indoor space 19.

<Right side structure part>
The right side structural portion 40R also includes an outside air intake port 41R, an outside air discharge port 42R, a duct 43R, and a register 46R, similarly to the left side structural portion 40L.

The outside air intake port 41R is provided so as to open forward on the front wall surface of the stay portion 21R of the right side mirror 20R. The outside air discharge port 42R is provided on the outer wall surface of the right side trim 11Rd exposed in the indoor space 19. One opening 43Ra of the duct 43R is connected to the outside air intake port 41R, and the other opening 43Rb of the duct 43R is connected to the outside air discharge port 42R. Therefore, the duct 43R connects the outside air intake port 41R and the outside air discharge port 42R.

The register 46R is arranged at the outside air discharge port 42R. The register 46R is used by the driver to adjust the flow rate and flow direction of the outside air discharged from the outside air discharge port 42R into the indoor space 19.

According to the implementation structure, when the temperature of the indoor space 19 (hereinafter referred to as "indoor temperature") rises to a temperature at which the driver feels uncomfortable, the driver operates the registers 46L and 46R to take in outside air. The outside air taken in from the ports 41L and 41R can be introduced into the indoor space 19 from the outside air discharge ports 42L and 42R to lower the indoor temperature. Alternatively, when the driver wants to suppress an excessive rise in the indoor temperature, the driver suppresses the excessive rise in the indoor temperature by introducing the outside air into the indoor space 19 from the outside air discharge ports 42L and 42R. Can be done.

Further, when any of the windowpanes 15F, 15LF, 15Rf, 15Lr and 15Rr (hereinafter, these windowpanes are collectively referred to as "windowpanes 15F and the like") becomes cloudy, the driver can use the outside air outlet 42L and By introducing outside air from 42R into the indoor space 19, fogging of the window glass 15F and the like can be eliminated. Alternatively, when the driver wants to suppress fogging of the window glass 15F or the like, the driver suppresses fogging of the window glass 15F or the like by introducing outside air into the indoor space 19 from the outside air discharge ports 42L and 42R. Can be done.

The present invention is not limited to the above embodiment, and various modifications can be adopted within the scope of the present invention.

For example, in the above embodiment, the outside air introduction structure may be configured to include only one of the left side structural portion 40L and the right side structural portion 40R.

Further, in order to open and close the ducts 43L and 43R, a shutter may be provided in each of the ducts 43L and 43R.

Drain holes may be provided in each of the ducts 43L and 43R in order to discharge foreign matter such as rain that has entered the ducts 43L and 43R to the outside of the ducts 43L and 43R.
