Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the frame structure of a small vehicle, and is provided with a portion that receives the upper end of a strut that serves as a shock absorbing mechanism for the front wheels.

[Prior art]

There are various types of small vehicles, but for example, a vehicle with a single occupant and intended for driving mainly in urban areas is designed to be as light as possible and to be in good condition in order to reduce the load on the engine. It is preferable that the vehicle has a comfortable ride. In order to obtain good riding comfort, it is necessary to provide a shock absorbing mechanism for the wheels, and one possible option is to use a strut suspension. When the strut suspension is used in this way, the upper end of the strut is supported by the vehicle body. Conventionally,
Since strut suspensions were not used in small vehicles such as those mentioned above, there was no structure to support the upper ends of the struts.

[Purpose of invention]

The purpose of this invention is to provide a frame structure for a small vehicle in which the upper end of the strut can be firmly supported by a frame formed of a pipe when using a strut suspension in a small vehicle. be.

[Structure of the idea]

The frame structure of the small vehicle of this invention has two main pipes in the front and back direction arranged side by side on the left and right.
In a small vehicle whose main frame is made by connecting two main pipes with a plurality of bridge pipes in the left and right direction, the front part of the main pipe is leveled at a higher position than the other parts, and the front bridge pipe is directed upward. It is formed into a U-shape, and two longitudinal pipes are connected between the frontmost bridge pipe and the rear bridge pipe, and the two
fixing both ends of a U-shaped pipe to each inside of the front part of the main pipe of the book, and connecting a vertical pipe between the middle part of the U-shaped pipe and the longitudinal pipe; A strut mounting bracket for supporting the upper end of the strut is attached to the upper part of the U-shaped pipe and the main pipe at the portion to which the U-shaped pipe is fixed.

By configuring it in this way, it is possible to receive the load of the strut with a small number of parts, and
The overall weight and cost can be reduced.

〔Example〕

Next, an embodiment of this invention will be explained with reference to the drawings.

In FIG. 1, 1 is a small vehicle, which includes a body 2 forming the lower half of the vehicle, a front panel 3 attached to the upper front part of the body 2,
The roof panel 4 whose front edge is joined to the front panel 3, the roll bar panel 5 whose front edge is joined to the roof panel 4, and the door 6 which is joined to the body main body 2 by a hinge (not shown) are all made of synthetic resin. It is manufactured.

FIG. 2 shows a frame provided inside the main body 2 of the small vehicle 1 shown in FIG. 1. In FIG. , 9 are arranged side by side on the left and right, and the main pipes 8 and 9 are connected by bridge pipes 10, 11, 12, and 13 in the left and right direction. The front parts 14 and 15 of the main pipes 8 and 9 are made to be horizontal at a higher position than other parts of the main pipes 8 and 9,
The bridge pipe 10 at the forefront is formed into an upward U-shape. Both ends of U-shaped pipes 16, 17 are fixed by welding to the inner sides of the front parts 14, 15 of the main pipes 8, 9 which are held horizontally at a high position.

On the other hand, two longitudinal pipes 18 and 19 are connected between the bridge pipe 10 at the front and the bridge pipe 11 at the rear, and the intermediate part of the longitudinal pipes 18 and 19 is connected to a U-shaped pipe. 1
A vertical pipe 2 is installed between the middle part of 6 and 17.
0 and 21 are combined. As a result, both ends of the U-shaped pipes 16 and 17 are supported by the main pipes 8 and 9, and the middle parts of the U-shaped pipes 16 and 17 are supported by the vertical pipes 20 and 21 and the front-back pipe. It is firmly supported by the main pipes 8 and 9 via the bridge pipes 10 and 11.

Strut mounting brackets 22, 23 obtained by molding a plate over the upper parts of the U-shaped pipes 16, 17 and the upper parts of the main pipes 8, 9 to which the U-shaped pipes 16, 17 are fixed. Attach as shown in FIG. 3 by welding the peripheral edges of the Holes 24 and 25 provided in strut mounting brackets 22 and 23 support the upper end of a strut (not shown) whose lower end is connected to a wheel-side member.

[Effect of idea]

In this invention, both ends of the U-shaped pipes 16 and 17 are directly supported by the main pipes 8 and 9, and the middle portions of the U-shaped pipes 16 and 17 are connected to vertical pipes 20 and 2.
1. Since the U-shaped pipes 16 and 17 are supported by the main pipes 8 and 9 through the longitudinal pipes 18 and 19 and the bridge pipes 10 and 11, the U-shaped pipes 16 and 17 are extremely firmly supported by the main pipes 8 and 9, and this U-shaped pipe Since the strut mounting brackets 22, 23 are installed across the U-shaped pipes 16, 17 and the upper part of the main pipes 8, 9 where the U-shaped pipes 16, 17 are fixed, the load from the struts can be reliably absorbed with a small number of parts. Can receive. Since this load is received by the main frame 7, sufficient safety can be ensured even if the vehicle body is made of synthetic resin. This allows the overall weight and cost to be reduced.
