[0002] With the gradual increase of electric bicycles, the public space area occupied by the electric bicycles is also gradually increased. The three-dimensional parking station for electric bicycles can effectively utilize space resources, thereby saving the land area occupied by the electric bicycles. However, solving the problem of self-ignition of the electric bicycles in the parking station or reducing the loss caused by the self-ignition is the primary problem to be solved for the three-dimensional parking station for electric bicycles.

[0003] A Chinese utility model patent with the patent number CN 217841065 U discloses an intelligent charging three-dimensional garage for electric bicycles. A plurality of parking units for accommodating parking plates are arranged inside the three-dimensional support in the main body of the garage, and a charging assembly is arranged on the parking units and the parking plates, so that the intelligent parking and charging of the electric bicycles are realized. Fire-fighting facilities are arranged in each parking unit, so that the safety hazard is eliminated. However, the vehicles are parked in a concentrated manner in the intelligent charging three-dimensional garage for electric bicycles. Once the individual vehicle catches fire during the charging process, the other vehicles will be ignited at the same time. Although the fire-fighting facilities are arranged, the vehicle that catches fire cannot be isolated from the other vehicles in the first time, and the spread of the fire cannot be inhibited. In addition, the intelligent charging three-dimensional garage for electric bicycles is a double-row multi-layer structure. Only one set of stacker is arranged between the two rows of garages. The storage and retrieval speed of the vehicles is slow. Not only the storage and retrieval efficiency of the vehicles is affected, but also the vehicles cannot be released in time when the fire occurs, and a large amount of loss is caused.

[0033] Preferably, the top, middle, and bottom telescopic rods 20 are interconnected by nesting. Internal pulleys can be added to reduce friction between the rods. The extension and retraction sequence of the three telescopic rods 20 and the steering sleeve 19 is as follows: as the traction rope 8 is lowered, the steering sleeve 19 and the telescopic rod 20 first extend and rotate the telescopic rod 20, then the three telescopic rods 20 extend sequentially, finally lowering the support device 5 to the ground; as the traction rope 8 is raised, the bottom telescopic rod 20 first retracts and rises, then the middle telescopic rod 20 retracts and rises, and finally the top telescopic rod 20 retracts and rises. When the top telescopic rod 20 retracts and rises, it slides relative to the steering sleeve 19, causing the telescopic rod 20 to rotate synchronously during its rise, thus achieving the steering of the support device 5. This lifting sequence requires that the friction between the telescopic rods 20 and the sliding friction between the telescopic rods 20 and the steering sleeve 19 are both less than their own weight and the weight of the support device 5. This lifting sequence can also be achieved by using single and double ratio ropes. Since single and double ratio ropes are currently a common technology in the field of rope lifting, they will not be discussed further here.

[0034] The non-obstruction-resistant three-dimensional parking device for electric bicycles of the present invention, when normally storing and retrieving vehicles, such as Figure 1 and Figure 2 As shown, the clutch device 6 is in the closed state. The tension of the telescopic device 2 is greater than the total weight of the support device 5 and the vehicle, but less than the driving force of the winding mechanism 7. The winding mechanism 7 first rotates forward to release the traction rope 8, causing the telescopic device 2 to drive the first telescopic arm 3 to extend. After the first telescopic arm 3 has extended, the second telescopic arm 4 extends as the traction rope 8 continues to be released, thereby lowering the support device 5 to the ground. After the vehicle is fixed on the support device 5, the winding mechanism 7 retracts the traction rope 8. Under the condition that the tension of the telescopic device 2 is greater than the total weight of the support device 5 and the vehicle, but less than the driving force of the winding mechanism 7, the traction rope 8 first drives the second telescopic arm 4 to retract. When the support device 5 is raised to the top, the winding mechanism 7 continues to wind the traction rope 8. At this time, the traction rope 8 overcomes the pressure of the telescopic device 2 to drive the first telescopic arm 3 to retract, so that the first telescopic arm 3 returns to its original position, and the vehicle storage and retrieval process ends. When a fire occurs, the clutch device 6 disengages, and the traction rope 8, which loses the driving force of the winding mechanism 7, becomes slack. The telescopic device 2 is no longer under the tension of the traction rope 8, thus satisfying the condition for the rapid extension of the telescopic device 2. This allows the first telescopic arm 3 to be extended instantly by the telescopic device 2, immediately moving the fire source away from other vehicles and isolating the burning vehicle from other vehicles, thus suppressing the spread of the fire. However, due to gravity, after the traction rope 8 slacks, the support device 5 and the vehicle will descend rapidly, the second telescopic arm 4 will extend rapidly, and the traction rope 8 will enter a stall state. The caliper 9 will clamp the traction rope 8 when it stalls, preventing the support device 5 from falling. This satisfies the rapid extension of the first telescopic arm 3 and avoids the problem of the support device 5 falling rapidly and damaging the vehicle.

[0035] Compared with the prior art, the technical scheme can realize normal access of the vehicles in a normal use state, each vehicle corresponds to a separate access system, the access of each vehicle does not interfere with each other, the access efficiency of the vehicles is greatly improved, and the vehicle on fire can be isolated from other vehicles at the first time when a fire occurs, the spread of the fire is effectively inhibited, and the safety and practicality of the stereo garage are greatly improved.

[0036] Embodiment two The same as embodiment one will not be repeated, and the difference is that, as shown in Figure 12 and Figure 13 , the device is a three-layer stereo garage, and can also be a four-layer, five-layer or multi-layer stereo garage, and the specific number of layers can be determined according to the specific use.

[0037] The above is only the preferred embodiment of the present application, and is not intended to limit the scope of the present application. Any equivalent changes and modifications made according to the content of the patent application scope of the present application shall belong to the technical scope of the present application.
