Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a body frame structure for a vehicle.
In particular, the present invention relates to a vehicle body frame structure suitable for use in automobiles such as one-box cars.

[Prior Art] Conventionally, a front suspension has come to be attached to the front suspension attachment portion 2 of a main frame 1' having a monocoque body structure of a one-box car as shown in Fig. 4. ing.

And this front suspension mounting part 2
Auxiliary equipment such as radiators and cooler condensers are now installed between them.

[Problem that the invention attempts to solve]

However, such conventional body frame structures for vehicles have the problem that they cannot adequately protect the radiator, cooler condenser, etc. located at the front of the vehicle. However, if a frame with a two-story structure consisting of a main frame and a sub-frame is used, there is a problem in that the flow of air to these members cannot be fully utilized without disturbing them.

The present invention aims to solve these problems by making it possible to reliably protect auxiliary equipment such as radiators and cooler condensers, and to prevent the flow of air flowing to these auxiliary equipment from being disturbed. It is an object of the present invention to provide a body frame structure for a vehicle that can reduce air flow and make sufficient use of air flow.

[Means for solving problems]

Therefore, in the vehicle body frame structure of the present invention, in the vehicle body frame, the body frame of the auxiliary equipment mounting portion is connected to the main frame disposed in the longitudinal direction of the vehicle, and the intermediate portion is located above the main frame. Or, it is located downward and has both ends connected to the main frame, and is arranged in almost the same direction as the main frame, and is formed in the longitudinal direction of the vehicle by a subframe consisting of an inner subframe member and an outer subframe member. The inner sub-frame member is formed as a two-story frame structure and faces inward in the vehicle width direction with respect to the outer sub-frame member, and the space formed between the main frame and the sub-frame is The present invention is characterized in that a guide plate is formed so as to be insulated from the space between the inner side in the width direction of the vehicle body and the outer side in the width direction of the vehicle body to guide the running wind rearward.

[Effect]

In the above-described vehicle body frame structure of the present invention, the traveling wind is guided rearward along the guide plate, so that the air flow is undisturbed between the auxiliary machinery and the body frame.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Figures 1 to 3 show a vehicle body frame structure as an embodiment of the present invention, and Figure 1 is a front perspective view thereof, and Figure 2 is a front perspective view thereof. is a side view (view from the arrow in FIG. 1), and FIG. 3 is a sectional view taken along the - line in FIG. 1. In FIGS. 1 to 3, the same reference numerals as in FIG. Shows something almost similar.

As shown in FIGS. 1 to 3, the front suspension mounting portion 2 of the one-box car has a main frame portion 3 formed by slightly bending the main frame 1 upward.
A two-story frame structure is provided, which includes a sub-frame 4 whose intermediate portion is located below the main frame 1 and whose both ends are connected to both ends of the main frame portion 3 of the main frame 1.

The subframe 4 is formed by combining an inner subframe member 4a and an outer subframe member 4b and has an internal cavity. The inner subframe member 4a extends to the main frame portion 3 so as to separate the space 9 existing between the top and bottom of the two-story frame structure into a space on the inside in the vehicle width direction and a space on the outside in the vehicle width direction. In other words, a guide plate 5 integrated with the inner subframe member 4a of the subframe 4 is disposed in front of the space 9 so as to close the front portion, and the inside of the two-story frame structure is formed into a flat surface extending toward the front of the vehicle.

Furthermore, in the internal space 10 between the left and right main frames 1 in the two-story frame structure, phase equipment 7 such as a radiator and a cooler condenser are provided.
An upper arm mounting member 6 and a shock absorber mounting member 8 are mounted between the main frame portion 3 and the subframe 4.

Since the vehicle body frame structure as an embodiment of the present invention is constructed as described above, these two
When the running wind is guided to the story frame structure,
The airflow is guided by the guide plate 5 and flows smoothly between the guide plate 5 and the auxiliary machinery 7 without being disturbed, and passes through the auxiliary machinery 7 while cooling the outer surface thereof, so that a high cooling effect can be obtained. Furthermore, since the subframe 4 is arranged so as to cover the lower end side surface of the auxiliary machinery 7, these auxiliary machinery 7
can be reliably protected.

[Effect of idea]

As described in detail above, according to the vehicle body frame structure of the present invention, in the vehicle body frame, the body frame of the auxiliary equipment mounting portion is connected to the main frame disposed in the longitudinal direction of the vehicle and the intermediate portion. is located above or below the main frame, has both ends connected to the main frame, and is disposed in approximately the same direction as the main frame, and is composed of an inner subframe member and an outer subframe member, and is a vehicle. The inner subframe member, which is formed as a two-story frame structure formed in the front-rear direction and faces inward in the vehicle width direction with respect to the outer subframe member, is located between the main frame and the subframe. It has a simple structure in which a guide plate is installed to block the space formed between the inner side in the width direction of the vehicle body and the outer side in the width direction of the vehicle body, and forms a guide plate for guiding the running wind to the rear. The following effects or advantages can be obtained.

(1) Ensure that auxiliary equipment such as radiators and cooler condensers are protected, and reduce disturbances to the air flow to these auxiliary equipment to fully utilize airflow. I can do it.

(2) By making the frame structure two-story,
The large input from the tires can be distributed by the upper and lower frames.

(3) Since the inner subframe member forms the guide frame, the number of parts and steps can be reduced.
