Description

  The present invention relates to a vehicle having a roof that covers a passenger compartment from above.

For example, some vehicles such as small electric vehicles have a roof that covers the vehicle compartment from above. In such a vehicle, it is preferable that the roof is designed high for getting into and out of the passenger compartment. However, if the roof is raised, the vehicle stability during traveling may be impaired, and the vehicle body style with a low center of gravity cannot be maintained. On the other hand, if the roof is designed low, it will be difficult to get in and out of the passenger compartment.
Therefore, a small vehicle configured to open and close the roof has been proposed (Patent Document 1).

  In particular, in a small vehicle, for example, there is no side door (see, for example, reference numeral 8 in FIG. 1 and FIG. 2 of Patent Document 1) as in an ordinary passenger car. For the purpose of protecting passengers (drivers). In some cases, a side bar is provided. However, when the side bar is provided, the side bar also becomes an obstacle when getting in and out of the passenger compartment. Therefore, a small vehicle having a sidebar that can be freely opened and closed has been proposed (Patent Document 2).

JP-A-2005-204 Japanese Patent Laid-Open No. 58-110378

However, in the small vehicle described in Patent Document 1, it is necessary to open the side door and open the roof when getting on and off. That is, it is complicated because two operations are always required when getting on and off.
Moreover, in the small vehicle of the said patent document 2, the problem that a roof becomes obstructive at the time of boarding / alighting is not solved. Moreover, since the side bar in this small vehicle is opened and closed by one hinge, there is also a problem that it is difficult to obtain high rigidity.

  The present invention has been made in view of such problems, and it is an object of the present invention to provide a vehicle that has a low center of gravity at the time of traveling, has improved boarding / exiting characteristics, and has enhanced sidebar member rigidity.

The present invention covers a vehicle compartment from above and a roof member whose front part is rotatably connected to the vehicle body,

The link mechanism composed of the vehicle body, the roof member, the side bar member, and the support member moves the front part of the side bar member rearward in conjunction with the rear part of the roof member moving upward. The vehicle is characterized in that the front part of the side bar member moves forward in conjunction with the rear part of the roof member moving downward (Claim 1).

  In the present invention, the link mechanism as described above is constituted by the vehicle body, the roof member, the side bar member, and the support member. Thereby, when the vehicle is traveling, the rear part of the roof member can be lowered, and when getting on and off, the rear part of the roof member can be raised upward. Then, the side bar member moves in conjunction with this, and the front part of the side bar member moves forward and is disposed on the side part of the passenger compartment during traveling, and the front part of the side bar member is disposed rearward when getting on and off. The

For this reason, the vehicle body can have a low center of gravity while the vehicle is running and the occupant can be protected by the side bar member. The space can be widened to prevent the roof member and the sidebar member from getting in the way.
As a result, it is possible to improve the ease of getting into and out of the passenger compartment while maintaining the running stability of the vehicle and the low center of gravity style.

  Moreover, since the said side bar member is connected with the support member and the roof member in the two places, the rigidity can be improved. That is, since an annular link mechanism is constituted by the vehicle body, the roof member, the side bar member, and the support member, the rigidity of the side bar member can be increased as the overall rigidity thereof increases. it can.

  As described above, according to the present invention, it is possible to provide a vehicle that has a low center of gravity at the time of traveling, has improved boarding / exiting characteristics, and has enhanced sidebar member rigidity.

  As shown in FIGS. 2 and 3, the link mechanism including the vehicle body 2, the roof member 3, the side bar member 4, and the support member 5 is connected to the side bar as the rear portion 32 of the roof member 3 moves upward. The front part 41 of the member 4 moves backward, and the front part 41 of the sidebar member 4 moves forward in conjunction with the rear part 32 of the roof member 3 moving downward.

And as shown in FIG. 2, the said link mechanism is in the 1st state in which the rear part 32 of the roof member 3 is a low position, and the rear part 32 of the roof member 3 is higher in the position than the first state as shown in FIG. In a certain second state, each can be fixed. As the fixing means, for example, a lock mechanism that locks the rotation at at least one place of the connecting portion of each member can be adopted.
The first state in FIG. 2 is a state when the vehicle is running, and the second state in FIG. 3 is a state when the passenger gets into and out of the passenger compartment 11.

The vehicle 1 of this example is a single-seater small electric vehicle, and is a four-wheel vehicle having four wheels 12. The roof member 3 is at least partially made of a transparent member (for example, a transparent resin member) so that the driver can visually recognize the front.
Further, a handle 33 is fixed to the lower surface of the side end portion of the roof member 3, and the roof member 3 is manually moved up and down by grasping the handle 33 or the roof member 3 itself. It is configured to be able to.

Moreover, as a raising method of the roof member 3, there is also a method in which the upper surface of the front extending portion 43 of the side bar member 4 described later is pushed downward by hand. Thus, the roof member 3 can be flipped up to the second state shown in FIG. 3 by the link mechanism of the support member 5, the side bar member 4, and the roof member 3. In this case, the boarding / alighting space 13 can be easily expanded even in the sitting posture in the passenger compartment 11.
Further, when the roof member 3 is lowered, the forward extending portion 43 of the side bar member 4 is lifted forward and upward from the second state of FIG. Even in the sitting posture, the roof member 3 can be easily lowered to the first state shown in FIG.

Further, the roof member 3 has a pair of ceiling portions 34 that are formed in a streamline shape that protrudes outward from the front portion 31 and the left and right end portions of the rear end portion of the ceiling portion 34. It consists of a pillar part 35. The rear portion 32 of the roof member 3 connected to the rear portion 42 of the sidebar member 4 is formed at the lower end portion of the pillar portion 35.
In addition, in this specification, the up-and-down front and back in each member shall be based on the positional relationship in the said 1st state (FIG. 2).
