Description

Technical Field

[0001] The invention relates to the technical field of electric bicycles, in particular to a novel electric two-wheeled vehicle with high safety performance. Background Art

[0002] With the vigorous development of the new energy industry, the market demand for low-cost and high-safety products is gradually increasing. It has become a trend to simplify the structure as much as possible, improve product safety performance and reduce costs while ensuring that product functions are not affected. Existing electric two-wheelers generally use the body as the installation space. In order to ensure the airtightness requirements of the body, the body is generally a closed space.

[0003] Since the body of the two-wheeled vehicle in the prior art is a sealed space, when the battery cells in the two-wheeled vehicle experience thermal runaway, the gas cannot be discharged in time, causing heat to spread throughout the battery system, thereby causing the two-wheeled vehicle to experience thermal runaway.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0008] Furthermore, the second connecting rod is located directly above the first connecting rod, the horizontal position of the second connecting rod is the same as that of the cover plate, the two second sleeves are respectively located directly above the two first sleeves, ropes are provided on both sides of one end of the cover plate, and the other end of the rope is fixedly connected to the second sleeve.

[0009] Furthermore, the rack moves up and down inside the placement groove, and the connecting rod 1 and the connecting rod 2 are fixedly connected to the inner wall of the shell.

[0010] Furthermore, the fire extinguishing structure includes an air storage box, which is fixedly connected to the upper sides of both ends of the placement groove, and an air outlet is provided at the lower end of the air storage box, and a sealing layer is provided inside the air outlet.

[0011] Furthermore, the alarm structure includes a fixed cylinder, which is fixedly connected to the upper end of the cavity, a sliding cylinder is slidably provided inside the fixed cylinder, a spring three is provided inside the sliding cylinder, a guide rod is provided at one end inside the fixed cylinder, the guide rod is fixedly connected to the spring three, an electrical connecting piece one is provided at one end of the sliding cylinder, and an electrical connecting piece two is provided at one end inside the fixed cylinder.

[0012] Furthermore, the cooling structure includes a refrigeration box, which is fixedly connected to the upper end of the placement plate. A circulating water pipe is provided at one end of the refrigeration box, and the circulating water pipe is fixedly connected to one end of the placement groove.

[0013] Furthermore, the gas inside the gas storage box is one or more of helium, argon, and carbon dioxide, and the material of the sealing layer is one or more of gallium, indium, gallium-indium alloy, polyethylene, and paraffin.

[0014] The advantages of the present invention compared with the prior art are: The electric push rod of the present invention is extended and retracted to drive the cover plate to move, and the carrier plate is located at the lower end of the placement groove. When the battery pack is placed on the upper end of the carrier plate, the weight of the battery pack compresses the second spring through the carrier plate, and a rack is installed at one end of the carrier plate, and a gear is installed on one side of the rack. The carrier plate moves downward with the second spring, thereby driving the rack to move downward, and then driving the gear to rotate; the rotation of the gear can drive the spring sheet to be reeled through the second ring, thereby pulling the rope through the second ring to reel, thereby driving the cover plate to move and seal the placement groove; when the battery pack needs to be taken out for inspection, the electric push rod is started to retract, thereby driving the cover plate to move and slide out of the placement groove, and the cover plate drives the gear to rotate through the rope and the spring sheet, thereby driving the rack to move upward, and the battery pack can be driven to move upward through the carrier plate, so as to facilitate removal.

[0015] In the present invention, when the temperature inside the cavity rises, the air pressure inside the cavity will increase, thereby pushing the sliding cylinder to move toward the inside of the fixed cylinder. The guide rod plays a positioning role and compresses spring three at the same time. The movement of the sliding cylinder drives the electrical connecting piece one to move toward the electrical connecting piece two. After the electrical connecting piece one and the electrical connecting piece two come into contact, an alarm can be sounded through a buzzer on the vehicle body and a warning light flashes to remind the user that the temperature inside the cavity is too high.

[0016] When an open flame appears inside the cavity of the present invention, the flame will burn off the blocking layer. The blocking layer material has high strength and low melting point, which ensures that the gas is stored inside the gas storage box and can burn quickly. The gas inside the gas storage box will block the burning of the open flame.

[0017] When the gas inside the cavity needs to be discharged, the present invention moves outward through the air outlet pipe, thereby driving the baffle to move outward. The baffle drives the slider to move outward inside the frame through the moving rod. The slider compresses spring 1. At this time, a gap is generated between the baffle and the limit ring, and hot air passes through and then flows out from the through hole. When the air pressure inside the cavity is stable, the spring 1 is restored, causing the baffle to return to the bottom of the limit ring, and the air outlet pipe is blocked, thereby ensuring the sealing effect of the cavity.
