Description

[Detailed Description of the Invention] The vehicle front proposal relates to an improvement of a power supply trolley in a system in which a vehicle having a drive motor runs by collecting current from a power supply trolley laid on the road surface.

When a power supply trolley is installed directly on a road surface indoors or outdoors, it is required that it is not adversely affected by environmental conditions such as wind, rain, or dust, and that there is no risk of electrical leakage or electric shock.

For this reason, the applicant proposed the following power feeding trolley.

In FIG. 1, a power supply trolley 1 includes a power supply trolley main body 2 made of a soft insulating material such as soft vinyl chloride,
2, conductive power supply lines 3, 3 buried within the main bodies 2, 2 over their entire length, a pedestal 4 for attaching the power supply trolley bodies 2, 2, and a guide member 5 fixed to the pedestal 4.
It is fixed to the road surface 7 by laying a soft adjusting plate 6 on the lower part of the pedestal 4.

A groove 8 extending in the same direction as the power feed line 3 is provided on the upper surface of the power supply trolley body 2 to a depth that reaches the power feed line 3, and a lid member 9 that opens and closes with respect to the groove 8 is provided. .

The lid member 9 is formed integrally with the power feeding trolley main body 2 at one side edge thereof, and is provided with a protrusion 11 on the other side edge thereof to elastically engage with the engaging groove 10 of the power feeding trolley main body 2. .

On the other hand, the current collector 20 (a part of which is shown in the figure) is connected to the guide member 5 of the power supply trolley 1 by means of guide rollers 23, 23, 23 pivotally supported by brackets 22, 22 fixed to the main body 21. You will be guided through the process by interacting with each other.

Reference numeral 24 denotes a current collector of the current collector 20, which is pressed against the power supply line 3 by a biasing means (not shown), and the current of the power supply line 3 passes through the current collector 24 and a lead wire 25 (not shown) connected to the current collector 24. Supplied to the vehicle's drive motor.

An opening roller 26 is attached to the main body 21 in front of the current collector 24, and a closing roller 2γ is attached to the main body 21 behind the current collector 24. It is pressed against member 9.

Thus, when the vehicle is running, the opening roller 26 of the current collector 20 opens the lid member 9 as shown in the left half of the figure so that the current collector 24 can collect current, and after the current collector 24 has passed, the closing roller 27 opens. As shown in the right half of the figure, the lid member 9 is pressed in the closing direction to elastically engage the protrusion 11 of the lid member 9 with the engaging groove 10 of the power supply trolley body 2, thereby sealing the power supply line 3. was.

However, in the conventional waterproofing mechanism of the power supply trolley, which is composed of the engaging groove 10 of the power supply trolley main body 2 and the protrusion 11 provided at the end of the lid member 9, fine sand, dust, etc., along with rainwater are trapped. As shown in FIG. 2, there was a problem in that the dust-proof performance of this part was degraded when it entered the engagement groove 10 of the power supply trolley main body 2.

In addition, the lid member 9 is required to be flexible because it needs to perform opening and closing movements, but the power supply trolley main body 2 is required to have a certain degree of rigidity because it is necessary to house and hold the power supply line 3. If the feeding trolley main body 2 and the lid member 9 are molded from the same material, this requirement cannot be met, and furthermore, since both are soft, the protrusions 11 deform when inserted into the hooking grooves 10, making it difficult to ensure reliability. There was a problem that the data was not inserted in some cases.

The present invention was developed with the aim of solving these conventional problems.The main body of the power supply trolley is made of a hard material, and a protrusion protruding in the vertical direction is provided on the side edge of the main body of the power supply trolley. A dust-proof mechanism for a power supply trolley is provided, in which a lid member made of a soft material is integrally molded on the other side edge of the trolley body, and an engaging groove groove that elastically engages with the protrusion is provided at the end of the lid member. .

The present invention will be explained below based on an embodiment shown in FIG.

In this embodiment, the same elements as those in the conventional example shown in FIG. 1 are given the same reference numerals.

In FIG. 3, the pedestal 40 is made of aluminum alloy, for example, and has a guide part 50 for guiding the current collector formed in the center, and insulating members 41 and 41 made of hard vinyl chloride, for example, are provided on both sides of the guide part 50. It is integrally installed by joining.

Then, on the bottom surface of the power supply trolley main body 2, there are 2
The insulating member 41,
41 is provided with two protrusions 42, 42 that snap engage with the respective engaging grooves 12, 12, and the power feeding trolley bodies 2, 2 are attached to the pedestal 40 via insulating members 41, 41.

A power supply line 3 made of a conductive material is embedded in the trolley bodies 2, 2 over the entire internal length thereof, and on the upper surface of the power supply trolley body 2, a line extending in the same direction as the power supply line 3 is deep enough to reach the power supply line 3. A groove 8 is provided.

A cover member 30 is provided for the groove 8 to prevent electrical leakage from the power supply line 3 and intrusion of dust and the like.

Note that the lid member 30 is normally closed, and when opened by an opening roller (not shown), it is in the state shown by the chain line.

A protrusion 32 is provided on one edge of the power feeding trolley main body 2 over its entire length.

The power feeding trolley main body 2 having the protrusion 32 is made of a highly hard material such as hard vinyl chloride.

The lid member 30 has a negative side edge formed integrally with the other side edge of the power supply trolley main body 2, and the other side line of the lid member 30 has an engagement groove that elastically engages with the protrusion 32 of the power supply trolley main body 2. 33 are provided.

The lid member 30 having the engaging groove 33 is made of a soft material such as soft vinyl chloride.

The pedestal 40 is installed on the road surface 7 via a ground height adjustment adjustment plate (mount spacer) 6 made of a soft material, and is fixed to the road surface 7 by anchor bolts (not shown).

Reference numeral 70 designates a protector for crossing other vehicles, the main body of which is made of, for example, an aluminum alloy, and an insulating member 71 made of, for example, hard vinyl chloride is integrally provided in the portion facing the outer surface of the power feeding trolley main body 2 of the protector γ0. Installation.

This protector 10 is fixed to the road surface 7 by anchor bolts 72 via protector spacers 13 made of a soft material.

According to the above-described configuration, since the power feeding trolley main body 2 is provided with the protrusion 32, sand, dust, etc. that try to collect on this part are scraped off when the lid member 30 is engaged.

In addition, sand that has accumulated in the engaging groove 33 of the lid member 30,
Dust, etc. will fall naturally due to gravity, and the dustproof performance in this area can be significantly improved.

Further, since the engaging groove 33 of the lid member 30 is made of a soft member, and the protrusion 32 of the power supply trolley main body 2 is made of a hard member, the advantage is that the engaging groove 33 of the lid member 30 can be easily engaged when elastically engaged. There is also.

As explained above, according to the present invention, the main body of the power supply trolley is made of a hard member, and a protrusion protruding in the vertical direction is provided on the -fUU edge thereof, and a protrusion is formed integrally with the other side edge of the main body of the power supply trolley. Since the end portion of the lid member made of a soft material is provided with an engaging groove that elastically engages with the protrusion, the dustproof performance of the power supply trolley can be significantly improved.
