It represents a different direction of the technological development of the stereo garage and is incomparable. The comb-tooth exchange stereo garage is popular for its simple structure, low energy consumption during vehicle exchange through the comb-tooth structure, short travel and time during vehicle storage and retrieval, which greatly improves the efficiency of vehicle storage and retrieval.

[0003] The patent announcement number is CN219281390U, and the patent name is a garage and its storage and access platform. It specifically discloses that "the storage and access platform of the garage includes a first comb tooth frame, a lifting mechanism and a second comb tooth frame, the first comb tooth frame includes a first comb tooth portion and a second comb tooth portion, the first comb tooth portion is arranged above the second comb tooth portion, the first comb tooth portion and the second comb tooth portion are connected by a connecting rod, and the first comb tooth portion can move up and down relative to the second comb tooth portion, which can reduce the original distance between the first comb tooth portion and the second comb tooth portion, thereby reducing the installation height requirement of the storage and access platform". The above-mentioned garage access platform can only allow AGV to enter and exit longitudinally, and the comb tooth exchange lifting height is limited, requiring the AGV to have a smaller height, and still requiring the foundation pit to have a larger depth. The lifting mechanism is placed on the outside to occupy additional foundation pit depth. Summary of the invention

[0084] The present invention also provides a method for using a vehicle exchange device, comprising the following steps:

[0085] The parking process is as follows:

[0086] A1: Before the vehicle enters the device, the lifting comb rack 22 is lowered to the lowest position (refer to Fig.17 ), at this time, the lifting comb frame 22 is flush with the upper surface of the comb support mechanism 3, and then the guide push mechanism 32 and the wheel block mechanism 33 are controlled to rise (refer to Fig.18 );

[0087] A2: Then the vehicle drives in, and the pulley assembly 34 cooperates with the guide and pushing mechanism 32 to push the vehicle to the center of the device (refer to

[0088] According to Fig.19 and Fig. 20 );

[0089] A3: Then the guide push mechanism 32 is folded and lowered to a low position, and the wheel blocking mechanism 33 is folded and lowered to a low position;

[0090] A4: The comb tooth lifting device 21 controls the lifting comb tooth frame 22 to rise, and the lifting comb tooth frame 22 and the comb teeth on the comb tooth mechanism 31 are interlaced during the process. The vehicle is exchanged once, that is, at this time, the vehicle is supported by the comb teeth on the lifting comb tooth frame 22 instead of the lifting comb tooth frame 22 and the comb teeth in the comb tooth mechanism 31.

[0091] Rack 22 is raised to the high position (refer to Fig.21 );

[0092] A5: Then control the filling mechanism 4 to rise to a high position to fill the gap caused by the rise of the lifting comb rack 22. At this time, the filling mechanism 4 is flush with the upper surface of the comb support mechanism 3 to provide support for the AGV to walk. The AGV is a special AGV for vehicle transportation, and its top is provided with comb teeth, which are staggered with the comb teeth on the lifting comb rack 22. The AGV can

[0093] Can enter and exit the device horizontally and vertically (refer to Fig.16 );

[0094] A6: The AGV passes through the walking track on the comb mechanism 31 and moves to the front of the lifting comb frame 22 through the filling mechanism 4.

[0095] Below (refer to Fig. 22 );

[0096] A7: Then control the filling mechanism 4 to descend to a low position to prevent the lifting comb rack 22 from being affected in the next step of descending (refer to

[0097] Fig.23 );

[0098] A8: The comb teeth lifting device 21 moves in the reverse direction to make the lifting comb teeth frame 22 drop to the low position. At this time, the comb teeth on the lifting comb teeth frame 22 and the comb teeth on the AGV are staggered and then fall down. During this process, the vehicle falls on the comb teeth of the AGV, completing the secondary exchange of the vehicle. That is, at this time, the vehicle is supported by the comb teeth on the lifting comb teeth frame 22 instead of being supported by the comb teeth on the AGV.

[0099] Support (refer to Fig.24 );

[0100] A9: Finally, the AGV can take the vehicle away from the device and move it to the corresponding parking space for the next parking process (refer to Fig.25 ).

[0101] The process of picking up the car is as follows:

[0102] B1: Before the AGV enters the device, the lifting comb rack 22 is lowered to the lowest position (refer to Fig.17 ), then rise

[0103] The comb tooth frame 22 is flush with the upper surface of the comb tooth support mechanism 3;

[0104] B2: The AGV moves the vehicle through the walking track on the comb mechanism 31 to the top of the exchange mechanism (such as Fig.24 ); B3: Then control the comb teeth lifting device 21 to make the lifting comb teeth frame 22 rise. At this time, the comb teeth in the lifting comb teeth frame 22 are staggered with the comb teeth on the AGV, and the lifting comb teeth frame 22 continues to rise until the vehicle is completely supported by the comb teeth on the lifting comb teeth frame 22. During this process, the vehicle is exchanged once, and the vehicle is raised to a high position together with the lifting comb teeth frame 21. That is, at this time, the vehicle is supported by the comb teeth on the lifting comb teeth frame 22 instead of the comb teeth on the AGV (refer to Fig.23 ); B4: Then the filling mechanism 4 is raised to a high position to fill the gap generated by the lifting comb frame 22. At this time, the filling mechanism 4 is flush with the upper surface of the comb support mechanism 3 to provide support for the AGV to walk (refer to Fig. 22 );

[0105] B5: The AGV passes through the walking track on the comb mechanism 31 and leaves the device through the filling mechanism 4;

[0106] B6: Then the filling mechanism 4 is lowered to a low position to prevent the lifting comb rack 22 from being affected in the next step of descending;

[0107] B7: The comb teeth lifting device 21 moves in the reverse direction to lower the lifting comb teeth frame 22 to the lower position. During this process, the vehicle falls on the comb teeth mechanism 31 to complete the secondary exchange of the vehicle. That is, at this time, the vehicle is supported by the comb teeth on the lifting comb teeth frame 22 and becomes supported by the inlet.

[0108] The comb teeth support on the lifting comb teeth frame 22 and the comb teeth mechanism 31 (refer to Fig. 20 );

[0109] B8: Finally, the driver drives the vehicle away from the device.

[0110] It should be noted that the vehicle pickup process is equivalent to the reverse action of the vehicle parking process.
