Abstract
A novel bicycle brake indicator comprises a power supply and an indicator lamp, wherein the power supply, the indicator lamp and a switch are in circuit connection. The novel bicycle brake indicator is characterized in that the switch consists of a first electric conduction rod and a second electric conduction rod, and the novel bicycle brake indicator further comprises a closed loop pipe, electric conduction liquid is filled in the pipe, the first electric conduction rod is inserted in the electric conduction liquid, and the second electric conduction rod is positioned on the liquid level of the electric conduction liquid. When a bicycle brakes, due to the inertia effect of the electric conduction liquid, the liquid level of the electric conduction liquid on the front side rises, the first electric conduction rod contacts the liquid level, so that the circuit is conducted, and the indicator lamp sends out signals.
Description
Technical field
The utility model relates to a kind of Warning light of bicycle, especially relates to a kind of indicating device that is used to indicate the bicycle brake signal.
Background technology
Bicycle is important one of the mode of riding instead of walk of China, but in the wagon flow of urban congestion, and if peak load conditions particularly on and off duty is the place ahead bicycle brake and the rear vehicle can not be understood at once, occurrence of traffic accident easily.
The bicycle brake indicating device of prior art is that braking signal switch mechanically links to each other with braking mechanism mostly, the connection of the action control braking signal switch through braking mechanism with close.But this kind method sensitivity is not high, and if the bicycle that other reason causes slows down, stoplight stop lamp can't be made indication.
The utility model content
The utility model utilizes object inertia that a kind of new bicycle brake indicator is provided, and it is simple in structure, easy to use, advantages of small volume and being quick on the draw.
Described new bicycle brake indicator comprises power supply and indicator lamp, and power supply, indicator lamp and switch are connected in circuit; It is characterized in that; Said switch is made up of first and second contact rod, also comprises an osed top loop pipe, and conductive liquid is housed in the pipe; Said first contact rod is inserted in the said conductive liquid, and said second contact rod is positioned on the conductive liquid liquid level.During brake, because the effect of inertia of conductive liquid, the liquid level of front side conductive liquid rises, and contact rod contact liquid level is connected circuit, and indicator lamp sends signal.
Preferably, the resistance that the front side conductive liquid rises when bicycle is slowed down is minimum, and the cross section of the loop pipe of selecting for use is for circular.
Description of drawings
Fig. 1 is the side-looking generalized section of the utility model embodiment 1.
Fig. 2 is the side-looking generalized section of the utility model embodiment 2.
Among the figure, 1: closed circular pipe, 2: conductive liquid, 3: the first contact rods, 4: the second contact rods.
The specific embodiment
As shown in Figure 1, the cross section of closed circular pipe 1 is circular, and level is installed on bicycle; A certain amount of conductive liquid 2 is equipped with in the inside of said closed circular pipe 1; First contact rod 3 is inserted in the rear side liquid level of conductive liquid 2, and second contact rod 4 is positioned at the liquid level top, front side of conductive liquid 2, does not contact liquid level.Generally speaking, circuit is in off-state, and when slowing down at bicycle brake or owing to other reason, conductive liquid 2 is owing to effect of inertia, and the liquid level of front side raises, and causes second contact rod 4 to contact with liquid level, and circuit is connected, the indication brake signal.The bottom of second contact rod 4 is designed to the distance of conductive liquid 2 front side liquid levels, and the liquid level that when bicycle brake, rises can touch the bottom surface of at least the second contact rod.If necessary, an indication delay timer can be set on this indicating device, promptly indicator lamp lights continued delay certain hour, to guarantee warning function.
As shown in Figure 2, the cross section of closed circular pipe 1 is square, i.e. side-looking is " returning " font loop pipe, and level is installed on bicycle, and remainder is with embodiment 1.
Claims (3)
1. a new bicycle brake indicator comprises power supply and indicator lamp, and power supply, indicator lamp and switch are connected in circuit; It is characterized in that; Said switch is made up of first and second contact rod, also comprises an osed top loop pipe, and conductive liquid is housed in the pipe; Said first contact rod is inserted in the said conductive liquid, and said second contact rod is positioned on the conductive liquid liquid level.
2. new bicycle brake indicator according to claim 1 is characterized in that, the cross section of said osed top loop pipe is circular.
