Abstract
The invention relates to a braking device, in particular to an electric vehicle braking device. The electric vehicle braking device comprises an electric vehicle hand brake and a braking device, wherein the electric vehicle hand brake is connected with the braking device; a pressure sensor is arranged on the electric vehicle hand brake and connected with an input end of a controller; an output end of the controller is connected with an input end of a switching circuit; and an output end of the switching circuit is connected with a series circuit, which is formed by a power supply and a motor. After the structure is adopted, the friction between a brake pad and a wheel can be effectively reduced so that the braking sensitivity can be also ensured in the long-term using process and the safety of the electric vehicle in running is guaranteed.
Description
Technical field
The present invention relates to the brake gear of a kind of brake gear, particularly a kind of battery-driven car.
Background technology
In the design process of battery-driven car, must there be bicycle disc brake to be used for when emergency situation, making that battery-driven car can the emergency brake braking.The prior electric car all is that electric vehicle brake directly is connected with brake gear, adopts brake rubber block under the most situation of said brake gear.But so, after the long-term use because the friction between brake rubber block and the wheel can cause the wearing and tearing of brake rubber block, thereby make that whole brake gear is insensitive, so the safety traffic of battery-driven car just can not get guaranteeing.
Summary of the invention
The technical issues that need to address of the present invention provide after a kind of long-term use the still sensitive bicycle disc brake of brake.
For solving above-mentioned technical matters; Bicycle disc brake of the present invention comprises battery-driven car parking brake and brake gear; Said battery-driven car parking brake is connected with brake gear, and said battery-driven car parking brake is provided with pressure sensor, and said pressure sensor is connected with the controller input end; Said controller output end is connected with the switch circuit input end, and the mouth of said switch circuit is connected with the circuit series of power supply and motor.
Said switch circuit is an aerotron, and the base stage of said aerotron is connected with controller output end.
After adopting said structure, because the battery-driven car parking brake is provided with pressure sensor, when brake, pressure sensor can be converted into the pressure of parking brake electric signal and be transferred to controller.Controller can be controlled the work of motor and stops through switch circuit; Make the speed of battery-driven car descend rapidly; Can reduce the friction between brake rubber block and the wheel by actv., can guarantee also in long-term use that like this brake is sensitive, guarantee the driving safety of battery-driven car.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the schematic circuit diagram of bicycle disc brake of the present invention.
Among the figure: 1 is pressure sensor, and 2 is controller, and 3 is aerotron, and 4 is motor, and 5 is power supply
The specific embodiment
Bicycle disc brake as shown in Figure 1 comprises battery-driven car parking brake and brake gear, and said battery-driven car parking brake is connected with brake gear, and the brake gear here adopts brake rubber block, can realize the emergency braking to battery-driven car through mechanical mode like this.Said battery-driven car parking brake is provided with pressure sensor 1; Said pressure sensor 1 is connected with controller 2 input ends; When with the battery-driven car parking brake battery-driven car being carried out emergency braking, can produce certain pressure, pressure sensor 1 converts this pressure into control signal and is input in the controller 2.Said controller 2 mouths are connected with the switch circuit input end, and the mouth of said switch circuit 2 is connected with the circuit series of power supply 5 with motor 4.
Said switch circuit is an aerotron 3, and the base stage of said aerotron 3 is connected with controller 2 mouths, and the grounded collector of said aerotron 3 is connected with the circuit series of power supply 5 and motor 4 between the emitter of said aerotron 3 and the collecting electrode.
Whether the base stage that controller 2 is controlled aerotron 3 through the control signal of pressure sensor 1 has the voltage input, and controller 2 can be controlled the conducting of aerotron 3 like this.Thereby further control the conducting of motor 4 pull up circuits.When brake, pressure sensor 1 produces signal makes aerotron 3 break off through controller 2, and the work of motor 4 will stop, and the speed of whole battery-driven car will descend rapidly.So just can reduce the friction between brake rubber block and the wheel by actv., make whole brake gear more safe and effective.
Claims (2)
1. a bicycle disc brake comprises battery-driven car parking brake and brake gear, and said battery-driven car parking brake is connected with brake gear, it is characterized in that: said battery-driven car parking brake is provided with pressure sensor, and said pressure sensor is connected with the controller input end; Said controller output end is connected with the switch circuit input end, and the mouth of said switch circuit is connected with the circuit series of power supply and motor.
