Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a breather device for a vehicle battery that discharges battery fluid overflowing from the battery.

(Prior Art) Some vehicles, such as motorcycles and tricycles, have a battery mounted at the rear of the vehicle body.

This battery is equipped with a breather device, which discharges overflowing battery fluid downward from the vehicle body when the vehicle body is tilted or when battery fluid is injected.

By the way, battery fluid uses dilute sulfuric acid,
If it adheres to the car body, it will corrode. For this reason, a breather hose is used to discharge the battery downward from the vehicle, but in vehicles where the battery is placed at the rear of the vehicle, the breather hose is longer and is secured with a clamp along the backstay that makes up the vehicle frame. and guide it downward.

(Problems to be Solved by the Invention) Incidentally, since the breather hose that discharges the battery fluid is long, it is difficult to secure a space for its arrangement, and there is a risk that it may interfere with other parts such as the seat and the seat cowl.

Further, a large number of clamps are required, which requires time and effort to assemble, and the passage is clogged depending on the support of the breather hose, which impedes smooth discharge of battery fluid.

This invention was made against the background of the above circumstances, and an object of the present invention is to provide a breather device for a car battery that can easily and reliably support a long breather hose and can smoothly discharge battery fluid. .

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes a battery mounted at the rear of the vehicle body, and overflows battery fluid from the battery to be discharged to the bottom of the vehicle through a breather hose. In the breather device for a vehicle-mounted battery, the breather hose is supported through a pipe frame.

(Function) In this invention, the reserve hose connected to the battery mounted at the rear of the vehicle body is led to the lower part of the vehicle through the pipe frame.

Therefore, the reserve hose can be simply inserted into the pipe frame without requiring a special installation space, and can be supported without using a clamp. Moreover,
There is no risk of interference with other parts such as the seat or seat cowl.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a body frame of a motorcycle, and a front fork 4 for suspending a front wheel 3 is rotatably supported on a head vibe 2 of the body frame 1.

A main frame 5 formed of a hollow pipe frame and a down tube 6 are connected to the head vibe 2, and the rear thereof is connected by a bracket 7. An internal combustion engine 8 is mounted in a space formed by the main frame 5 and the down tube 6.

A rear arm 9 is pivotally supported by the bracket 7 via a suspension, and a rear wheel 10 is suspended from the rear arm 9.

A seat rail 11 is connected to the center of the main frame 5 so as to extend rearward, and the seat rail 11 is connected to the rear end 5 of the main frame 5 via a backstay 12.
It is supported by a.

The backstay 12 is formed of a pipe frame,
The upper end 12a of the back tee 12 is bent and abutted against the lower surface of the seat rail 11 and welded thereto, and the lower end 12b is inserted into the rear end 5a of the main frame 5 and welded thereto.

There is a seat 13 on the seat rail 11! ! A battery 14 is mounted behind the seat 13. Both sides of the battery 14 and the seat rail 110 are covered with a seat cowl 15.

The upper end of a breather hose 16 is connected to the upper part of the battery 14, this breather hose 16 passes inside the backstay 12, and its lower end 16b is connected to the backstay 1.
2 from the open part 12c of the lower end 12b of the main frame 5.
The hose hole 7a of the bracket 7 passes through the opening 5b of the rear end 5a and hangs downward. The breather hose 16 inserted through the backstay 12 is positioned and supported by a seal member 17 while being sealed.

Next, the operation of this embodiment will be explained.

Battery fluid may overflow when the vehicle body is tilted or when replenishing battery fluid. This overflowing battery fluid is guided from the rear of the vehicle body to the rear of the internal combustion engine 8 by the breather hose 16 and is discharged downward. In this way, the battery fluid using dilute sulfuric acid is discharged without adhering to the vehicle body, so metal parts are not corroded by the battery fluid.

By the way, the breather hose 16 extends from the rear of the seat to the rear and lower part of the internal combustion engine 8, and is relatively long. & Since it is supported through the backstay 12 extending to the end portion 5a, there is no need to secure a special installation space. Moreover, it can be easily and reliably supported without requiring a fixing member.

Furthermore, since the breather hose 16 is supported through the backstay 12, the seat 13 and seat cowl 15
It is possible to reduce interference with other parts such as.

Therefore, there is no fear that a portion of the breather hose 16 may be crushed due to interference with other parts, causing the battery fluid to become clogged or damaged, and can be reliably discharged downward from the vehicle.

Moreover, since the breather hose 16 is not visible from the outside, it looks good.

(Effects of the Invention) As described above, in this invention, a relatively long pleaser hose for discharging battery fluid overflowing from a battery is supported through the pipe frame, so there is no need to secure a special space for arranging the pleaser hose. , can be easily and reliably supported without using clamps. Furthermore, since it does not interfere with other parts such as the seat or seat cowl, the battery fluid can be smoothly discharged downward from the vehicle without fear of clogging.
