Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement in the mounting structure of vehicle auxiliary equipment that is attached to the body of an automobile.

(Prior Art) Conventionally, as a structure for attaching automobile auxiliary equipment to the vehicle body, for example, as described in Japanese Utility Model Application Publication No. 57-63726, a fuel pump as a vehicle auxiliary equipment was installed via a bracket on the lower surface of the rear floor. The one I installed was hot. However, in this conventional structure, the fuel pump is exposed outside the vehicle body and close to the ground, and there is a problem in that the fuel pump may be damaged by flying stones or the like hitting it while the vehicle is running. In order to solve this problem, it may be possible to provide a cover to cover the fuel pump, but if this is done, the number of parts and assembly man-hours will increase, resulting in higher costs.

(Purpose of the invention) The present invention can prevent vehicle auxiliary equipment such as the fuel pump from being damaged by flying stones, etc. without increasing the number of parts. It is an object of the present invention to provide a structure for mounting auxiliary equipment on an automobile that will not be damaged.

(Structure of the invention) The present invention forms an opening on the lower surface of the closed cross section formed by the rear seat cross member and the floor part, provides a removable lid member in the opening, and attaches a fuel pump to the upper surface of the lid member. This allows the vehicle auxiliary equipment to be housed within the closed section formed by the rear seat cross member and the floor.

(Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the figures, 1 is a front floor, and a rear floor 2 is disposed slightly above this, following the front floor 1. rear floor 2
The rear portion 2a of the vehicle is further bent upward, and a fuel tank 3 as a vehicle auxiliary device is attached below the rear portion 2a.

A rear seat cross member 4 is disposed on the inside of the vehicle at the connection between the front floor 1 and the rear floor 2, and is used to join the two floors 1 and 2 and to attach the rear seat 10. The rear seat cross member 4 has a channel-shaped cross section and extends in the vehicle width direction, and a reinforcement 14 having substantially the same shape as this and for reinforcing the rear seat cross member 4 is fixed to the inside thereof. The flange portion 4b at the lower end of the front wall portion 4a of the rear seat cross member 4 is fixed to the rear end portion 1a of the front floor 1, and the front end portion of the rear floor 2 is located in the middle of the front wall portion 14a of the reinforcement 14. 2b is fixed, and furthermore, the reinforcement 14 and the rear wall portions 14b, 4c of the rear seat cross member 4 are fixed.
The flange parts 14c and 4d are both attached to the rear floor 2.
The rear seat cross member 4 and the rear floor 2 form a closed cross section 9. Note that the gap between the rear seat cross member 4 and the reinforcement 14 is filled with glass wool 12.

A rectangular opening 2c is formed in the lower portion of the rear seat cross member 4 of the rear floor 2, and a lid member 5 is attached to the lower surface of the opening. The lid member 5 consists of a horizontal portion 5a and an inclined portion 5b that is bent downwardly toward the exterior of the vehicle.A mounting flange portion 5c is formed on the peripheral edge of the horizontal portion 5a, and the flange portion 5c is attached to the rear floor 2. , is detachably attached to the reinforcement 14 and side sill 11 of the rear seat cross member 4 with bolts 6.

The leg portions 7a of the fuel pump 7 are bolted to the upper surface of the horizontal portion 5a of the lid member 5 via anti-vibration rubber 8, so that the fuel pump 7 has a closed section formed by the rear seat cross member 4 and the rear floor 2. It is housed within 9. Furthermore, 7b
is the above fuel tank 3 and the above fuel pump 7
7c is a suction pipe communicating with the fuel pump 7 and the engine, and 7c is a discharge pipe communicating the fuel pump 7 with the engine.

In this manner, in the structure of this embodiment, the fuel pump 7 is accommodated within the closed section 9, so that so-called dead space can be effectively utilized. Furthermore, since the lid member 5 acts as a cover, flying stones and the like will not directly hit the fuel pump 7, and damage to the fuel pump 7 can be prevented. Also, reinforcement 1
4. The glass wool 12 can reduce the transmission of pump noise into the vehicle interior, and even if the rear of the vehicle is collided with another vehicle, the fuel pump 7 can be used to protect the rear seat cross member 4 and the rear floor, which are reinforced with reinforcements 14. 2, there is less risk of the pump 7 being damaged.

In addition, the fuel pump 7 is attached via the removable member 5, and therefore the fuel pump 7 can be easily attached, detached, maintained, etc., and can be attached and detached with fewer man-hours during work. .

In the above embodiment, the front floor 1 and the rear floor 2 are connected at different levels, but the front floor 1 and the rear floor 2 may be connected on the same plane. Further, although the seat cross member 4 is attached to the upper surface of the rear floor 2, it may be disposed on the upper surface of the front floor 1, or further across both floors 1 and 2.

Further, in the above embodiment, the fuel pump 7 has been described as an example of a vehicle auxiliary device, but the present invention is not limited to this, and the same effects as described above can be obtained with other vehicle auxiliary devices.

(Effects of the invention) As described above, according to the vehicle auxiliary device mounting structure of the present invention, a vehicle auxiliary device such as a fuel pump can be mounted within the closed cross section formed by the front floor or rear floor and the rear seat cross member. By storing the fuel pump, it is possible to prevent damage to vehicle auxiliary equipment such as the fuel pump caused by flying stones without increasing the number of parts, and it is also possible to prevent vehicle auxiliary equipment such as the fuel pump from being damaged in the event of a rear collision of a car. In addition, the opening on the lower surface of the closed section is covered with a removable lid member, and auxiliary equipment is attached through this, making it easy to install, remove, and maintain the auxiliary equipment. This has the effect that it can be attached and detached with fewer man-hours during work.
