Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, in particular to an intelligent electric bicycle anti-spontaneous combustion device. Background Art

[0002] Electric vehicles are prone to spontaneous combustion during the charging process, especially in the summer when the temperature is too high. The internal circuits of electric bicycles are prone to aging and causing short circuits, leading to spontaneous combustion. Therefore, anti-spontaneous combustion devices need to be installed to avoid spontaneous combustion.

[0003] Among them, the existing electric bicycle power-off anti-spontaneous combustion devices on the market mainly use relays, which have the following disadvantages: large contact resistance, the contacts are usually made of silver-cadmium alloy, the bridging area is small, resulting in large contact resistance, easy to heat up and produce adhesion, affecting long-term reliability, and the relay automatically disconnects and connects according to the thermostat switch, which means that even if the vehicle has the risk of high-temperature spontaneous combustion, after the relay is disconnected, it will still be reconnected after the temperature drops, which will cause the electric vehicle to still have the risk of spontaneous combustion when in use. Based on this, the utility model designs an intelligent electric bicycle anti-spontaneous combustion device. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an intelligent electric bicycle anti-spontaneous combustion device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An intelligent electric bicycle anti-spontaneous combustion device, wherein the air switch is connected to the main power supply of the electric bicycle, and comprises a control box connected to the air switch, wherein a lever connected to the air switch is connected in the control box, wherein one side of the lever in the control box is connected to an electromagnet, wherein the electromagnet is connected to an electric control component, wherein two sides of the control box are respectively connected to a locating pin so that the control box is limitedly connected to the air switch, and a reset switch is arranged on the side of the control box, wherein the reset switch is connected to the lever and the air switch.

[0007] Preferably, the electronic control component includes a control board, which is connected to a plurality of temperature probe interfaces, and the plurality of temperature probe interfaces are respectively connected to three temperature sensors through wiring, and the three temperature sensors are respectively arranged at the battery, electrical component connector and vehicle line connector in the electric bicycle.

[0008] Preferably, the critical temperature of each temperature sensor is set to 60°C.

[0009] Preferably, a waist-shaped groove is provided in the control box to meet the movement of the lever.

[0010] Preferably, a wire groove for passing the wire harness is provided on the side of the control box, and a mounting platform for accommodating the electromagnet is provided in the control box, and the electromagnet is connected to a micro switch.

[0011] Compared with the prior art, the utility model has the following advantages: when in use, the temperature of the battery, electrical component connectors and vehicle line connectors is determined based on electrical signals, and the risk of spontaneous combustion at multiple locations is determined to determine whether the temperature is greater than the preset critical fire temperature of the electric bicycle. Compared with the prior art, the utility model has a stronger anti-spontaneous combustion capability. At the same time, the air switch has the characteristic of not reconnecting after power failure and requires manual reset. Therefore, compared with the prior art of using relays for temperature detection, the utility model avoids the problem of automatic reconnection of the relay after the temperature drops, thereby reducing the safety hazards of electric vehicles.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] like Figure 1-2 As shown, an intelligent electric bicycle anti-spontaneous combustion device includes a control box 1 connected to an air switch, a lever 2 connected to the air switch is connected in the control box 1, a waist-shaped groove 7 for satisfying the movement of the lever 2 is opened in the control box 1, an electromagnet 3 is connected to the lever 2 on one side of the control box 1, the electromagnet 3 is connected to an electric control component 4, and a positioning pin 5 is connected to each side of the control box 1 so that the control box 1 is limitedly connected to the air switch, that is, the control box 1 is externally connected to the air switch, and the power supply of the electric bicycle is controlled by controlling the air switch, and a reset switch 6 is arranged on the side of the control box 1, the reset switch 6 is connected to the lever 2 and the air switch, and the air switch is turned on again by the reset switch 6.

[0017] The electric control component 4 includes a control panel 41, and a plurality of temperature probe interfaces 42 are connected to the control panel 41. The plurality of temperature probe interfaces 42 are respectively connected to three temperature sensors through wiring. The critical temperature of each temperature sensor is set to 60°C. The three temperature sensors are respectively arranged in the battery, the electrical component connector (failure of the electrical component and the contact connection may cause local overheating, which may cause combustion) and the whole vehicle line connector (circuit aging and insulation layer damage, the electric vehicle is used for too long, the circuit is prone to aging and short circuit, especially when the external temperature is too high, it is more likely to cause combustion. The above three parts are prone to overheating problems. Therefore, the temperature monitoring of the above three positions can effectively achieve the effect of preventing spontaneous combustion. The control panel 41 is connected to a signal light 43, and the control panel 41 is also provided with an inlet and an outlet for the thermostat power supply.

[0018] The side of the control box 1 is provided with a wire groove 8 for the wiring harness to pass through, so as to facilitate the entry of the power supply wires of the thermostat and the connecting wires of the temperature sensor. The control box 2 is provided with a mounting table 9 for accommodating the electromagnet 3, and the electromagnet 3 is connected to a micro switch 10. The function of the micro switch 10 is that when the circuit in the control box 1 is installed on the electric bicycle and the circuit is connected, a micro current will exist on the electromagnet 3, so that the electromagnet 3 will drive the lever 2 to move, and the problem of closing the air switch will occur, that is, there is a problem of interfering with the normal operation of the air switch. By setting the micro switch 10, the micro switch 10 can be closed before the circuit in the control box 1 is connected to avoid current passing through the electromagnet 3, and then the micro switch 10 can be turned on after the circuit current in the control box 1 is stable, so that the electromagnet 3 can work normally.

[0019] When the utility model is in use, the temperature sensors at three positions determine whether the temperature at the battery, the electrical device connector and the vehicle line connector is greater than the preset critical fire temperature of the electric bicycle according to the electrical signal (the critical fire temperature of the wire stipulated by the state is 70 degrees), and the set temperature of this product is 60 degrees. When the probe of the temperature sensor senses that the temperature at any of the three positions is greater than 60 degrees, it sends an electrical signal to the thermostat. After receiving the electrical signal, the electromagnet 3 sucks back to drive the lever 2 (the electromagnet mechanical lever is placed in the small window of the air switch). The lever 2 pulls back to trigger the button of the air switch, forcibly disconnecting the power supply of the air switch, so that the power supply in the electric bicycle is cut off, thereby preventing the temperature from continuing to rise to the critical fire temperature of the wire, and the temperature controller senses the critical fire temperature of the wire and disconnects the power supply of the air switch in only 0.5 milliseconds to realize the power off of the air switch, so it has a higher safety quality and a faster response speed, and can effectively prevent the hidden danger of spontaneous combustion in the driving, parking, charging, and static aspects of the electric vehicle.

[0020] After the air switch is powered off, the reset switch 6 is pressed manually, and the vehicle can continue to be powered on and run normally, so that the electric bicycle can be sent for repair.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
