Abstract
The utility model discloses a gravity-type direction indicator which comprises three layers, the bottom layer is provided with a battery box, the upper layer is provided with two metal spiral coils, the two metal spiral coils are connected by using a guide rail made of insulating materials, a metal panel is arranged between the bottom layer and the upper layer, and two indicating lamps are arranged on the metal panel; a metal ball is arranged in the metal spiral coil, and the metal ball can roll along the metal spiral coil on the metal panel; and the battery box, the indicating lamps, the metal spiral coils, the metal balls and the metal panel are connected in series. Through a simple device, the gravity-type direction indicator disclosed by the utility model can help novice driver friends to learn the directing of own wheels at any time.
Description
Technical field
The utility model relates to a kind of electronic vehicle device, in particular, relates to a kind of gravity type boat davit arm for direction indicator.
Background technology
Along with China's economy constantly develops, people's living standard improves constantly, and automobile consumption also constantly heats up.Usually,, when driving a car, often do not make wheel of the bus clear and whether face the place ahead as new hand's chaufeur.In order to prevent that excessive the turning to of bearing circle can cause danger in running at high speed, the angle that bearing circle rotates will be far longer than the angle that automobile steering roller rotates.Bearing circle need rotate 2 circles half (nearly 900 °) could let automobile steering roller " kill " (about 50 °).So when stopping on narrow parking stall, left-hand rotation right-hand rotation bearing circle is easy to confuse.
The utility model content
The utility model provides a kind of gravity type boat davit arm for direction indicator to the technical matters that exists in the above-mentioned prior art.Through simple mechanism, help new hand's chaufeur friend can understand the sensing of own wheel at any time.
The utility model is realized through following technical scheme:
A kind of gravity type boat davit arm for direction indicator, said indicating device comprises three-decker, bottom is a battery case; The upper strata is two metal spiral coils; The guide rail made from insulating material between two metal spiral coils is connected, and is metal decking between bottom and the upper strata, and two indicator lamps are arranged on the metal decking; A metal balls is arranged in the metal spiral coil, and metal balls can be rolled along the metal spiral coil on metal decking; Battery case, indicator lamp, metal spiral coil, metal balls and metal decking form and are connected in series.
The positive pole of said battery case power supply connects the positive pole of indicator lamp, and the indicator lamp negative pole connects the metal spiral coil again; The negative pole of battery case power supply connects metal decking.
The negative pole of said battery case power supply connects the negative pole of indicator lamp, and the indicator lamp positive pole connects the metal spiral coil again; The positive pole of battery case power supply connects metal decking.
Connect a current-limiting resistance between said battery case and the indicator lamp.
The beneficial effect that the utility model brought is following:
In the technical scheme that the utility model adopted, when metal balls was rolled in the metal spiral coil, ball was connected the entire circuit conducting to metal decking and metal spiral coil just as a contact; When rolling in the metal spiral coil of metal balls on the left side, the indicator lamp on the left side is bright; When rolling in the metal balls metal spiral coil on the right, the indicator lamp on the right is bright, through this simple mechanism, helps new hand's chaufeur friend can understand the sensing of own wheel at any time.
Description of drawings
Fig. 1 is the birds-eye view of the utility model specific embodiment;
Fig. 2 is the circuit connection diagram of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain, but following content is not used in the protection domain that limits the utility model.
Like Fig. 1, shown in Figure 2, the gravity type boat davit arm for direction indicator that the utility model provides can stick on the vehicle steering card; Comprise three-decker; Bottom is a battery case 8, and the upper strata is that the guide rail made from insulating material between two metal spiral circles 1 and 5, two the metal spiral circles 6 is connected; Be metal decking 4 between bottom and the upper strata, two indicator lamps 2 and 3 are arranged on the metal decking 4; A metal balls 7 is arranged in the metal spiral coil 1 (5), and metal balls 7 can be rolled along metal spiral coil 1 (5) on metal decking 4.
The positive pole of battery case power supply (negative pole) connects the positive pole (negative pole) of indicator lamp, and indicator lamp negative pole (positive pole) connects the metal spiral coil again; The negative pole of battery case power supply (positive pole) connects metal decking.
Usually, current-limiting resistance of series connection between battery case and indicator lamp, this current-limiting resistance plays a protective role to circuit.
The principle of work of the utility model: because general bearing circle downward-sloping certain angle always, on the guide rail 6 that metal balls 7 should stop at two metal spiral circles 1 under the initial condition, insulating material is made between 5, indicator lamp 2,3 is not worked.In case bearing circle rotates, metal balls 7 is because the metal spiral circle 1,5 to a side is rolled in the effect of gravity; Ball becomes the contact between spiral coil and the metal decking 4, and circuit is connected, and the indicator lamp 2,3 on the panel is started working; And bearing circle to which side rotates; Which side ball just rolls to, and the spiral coil of which side and the circuit between the metal decking are connected, and corresponding indicator lamp is started working.So just can prevent that bearing circle from rotating after the circle, the driver can think the illusion that bearing circle has been ajusted by mistake.
