[0090] With reference to Figures 1 to 12 The present application provides a parking system, the parking system comprising a parking area, an exchange device 100 and a carrier 200. The carrier 200 is movable between the parking area and the exchange device 100. Optionally, the carrier 200 is a carrier robot.

[0091] The exchange device 100 has a travel area, the exchange device 100 comprising a chassis 110, an exchange frame 120 and a carrying platform 130.

[0092] The exchange frame 120 is movably connected to the chassis 110 in a height direction DH of the exchange device 100 between a low position and a high position. The exchange frame 120 in the low position at least partially forms the travel area, and the exchange frame 120 in the high position is above the chassis 110 to lift a vehicle out of the travel area. In the state that the exchange frame 120 is in the low position, a vehicle can leave and / or enter the travel area. In the state that the exchange frame 120 is in the high position, the position of the exchange frame 120 no longer occupies a passage of the carrier 200. The exchange frame 120 not only serves to support a vehicle, but also frees up the travel area for use by the carrier 200.

[0093] In the state that the exchange frame 120 is in the high position, the carrying platform 130 is movably connected to the base frame 110 in the width direction DW of the exchange device 100 between an avoiding position and a carrying position, the projection of the carrying platform 130 in the height direction DH is staggered with the projection of the exchange frame 120 in the height direction DH in the avoiding position, and the carrying platform 130 at least partially forms a walking area in the carrying position. In the state that the exchange frame 120 is in the high position and the carrying platform 130 is in the carrying position, the carrier 200 can leave and / or enter the walking area. When the exchange frame 120 vacates the walking area for the carrier 200, the carrier 200 can walk in the walking area formed by the carrying platform 130 in the carrying position. The carrying platform 130 can be provided as a flat plate or a comb structure with small spacing. The carrying platform 130 provides a smooth support surface for the carrier 200, reduces the shaking that may be generated during the driving of the carrier 200, and ensures the smooth movement of the vehicle during the access process.

[0094] In the present scheme, the alternating work of the exchange frame 120 and the carrying platform 130 makes the use of the walking area more efficient. In the state that the exchange frame 120 is in the high position, the carrying platform 130 is movably connected to the base frame 110 in the width direction DW of the exchange device 100 between an avoiding position and a carrying position. In the state that the carrying platform 130 is in the avoiding position, the exchange frame 120 is movably connected to the base frame 110 in the height direction DH of the exchange device 100 between a low position and a high position. When the carrying platform 130 is in the avoiding position, the exchange frame 120 can be smoothly lifted, ensuring that the vehicle can enter or leave the exchange device 100. When the carrying platform 130 enters the carrying position, the exchange frame 120 is in the high position to avoid conflict with the carrying platform 130. In this way, the exchange frame 120 and the carrying platform 130 cooperate with each other in different states, so that the vehicle can be smoothly transferred from the exchange frame 120 to the carrier 200, or vice versa.

[0095] In some embodiments of the present application, the base frame 110 includes a plurality of first combs 111 extending in the width direction DW of the exchange device 100 and spaced apart in the length direction DL of the exchange device 100. The first combs 111 can be matched with the exchange frame 120 and the carrying platform 130, respectively.

[0096] The cooperation structure of the base frame 110 and the exchange frame 120 of the exchange device 100 according to an embodiment of the present application will be described in detail below. Figures 1 to 7 The cooperation structure of the base frame 110 and the exchange frame 120 of the exchange device 100 according to an embodiment of the present application will be described in detail below.

[0097] The exchange frame 120 is movably connected to the base frame 110 in the height direction DH between a low position and a high position.

[0098] The switching frame 120 comprises a plurality of second combs 121 extending along the width direction DW and spaced along the length direction DL. In the state that the switching frame 120 is located at the low position, the second combs 121 are staggered with the first combs 111, and the first combs 111 and the second combs 121 form a walking area to carry the vehicle; the second combs 121 can lift the vehicle, and in the state that the switching frame 120 is located at the high position, the second combs 121 are located above the first combs 111, so that the vehicle is spaced from the first combs 111 along the height direction DH. When the second combs 121 are staggered with the first combs 111, a stable walking area is formed to support and carry the vehicle. It can be understood that when the second combs 121 are staggered with the first combs 111, the upper surfaces of the second combs 121 are flush with the upper surfaces of the first combs 111. When the vehicle enters, the area where the first combs 111 and the second combs 121 are staggered forms a carrying surface of the vehicle, and the vehicle can walk relatively stably on the first combs 111 and the second combs 121. When the switching frame 120 is raised to the high position, the lifting of the second combs 121 will make the vehicle separate from the first combs 111, that is, the second combs 121 carry the vehicle, and at this time the vehicle will not walk, so that the stable parking of the vehicle can be ensured.

[0099] The switching frame 120 lifts the vehicle to an appropriate height, which provides sufficient space for the subsequent entry and exit of the carrier 200 into the switching device 100. Since the spacing between adjacent first combs 111 is relatively large with respect to the diameter of the wheels of the carrier 200, it is necessary to provide a carrying platform 130 to provide a stable walking area for the carrier 200.

[0100] Optionally, the switching frame 120 is provided in two groups. The two groups of switching frames 120 are spaced along the width direction DW of the chassis 110. The two groups of switching frames 120 correspond to the left and right sides of the vehicle respectively. By providing two groups of switching frames 120, each group is aligned with the left and right sides of the vehicle respectively, the vehicle can be more accurately supported, and the horizontal parking and stable carrying of the vehicle can be ensured. Prevent the vehicle from tilting, shaking and other phenomena during access. The two groups of switching frames 120 also reduce the pressure on a single switching frame 120, making the overall operation of the device more flexible.

[0101] In some embodiments of the present application, the switching device 100 further comprises a second driving assembly 150 for driving the switching frame 120 to translate. The second driving assembly 150 functions to drive the switching frame 120 to move along the height direction DH in the switching device 100.

[0102] The second driving assembly 150 comprises a guide rail 151 and a guide wheel 152. The guide rail 151 extends along the height direction DH. The guide wheel 152 is capable of sliding along the guide rail 151. The cooperation between the guide rail 151 and the guide wheel 152 ensures the smooth and stable lifting process of the exchange frame 120, avoiding problems such as vibration, deviation or jamming. Among them, one of the guide rail 151 and the guide wheel 152 is arranged on the chassis 110; the other of the guide rail 151 and the guide wheel 152 is arranged on the exchange frame 120. Optionally, the guide rail 151 is arranged on the chassis 110, and the guide wheel 152 is arranged on the exchange frame 120.

Optionally, the second roller 122 is arranged at the position corresponding to the wheel of the vehicle.

[0108] Optionally, the second roller 122 is provided in plurality.

[0109] In some embodiments of this utility model, the exchange device 100 further includes two sets of centering members 160 spaced apart along the width direction DW and movable along the width direction DW. As mentioned above, the exchange rack 120 is configured in two sets, and the two sets of centering members 160 are arranged one-to-one with the two sets of exchange racks 120. The two sets of centering members 160 are symmetrically arranged, and the two sets of centering members 160 can move closer or further away from each other to place the vehicle in the center position. The two sets of centering members 160 are symmetrically arranged on both sides of the travel area of ​​the exchange device 100 along the width direction DW. By moving closer or further away from each other, the centering members 160 ensure that the vehicle is automatically centered after entering the parking position, so that the vehicle is parked in the center position of the parking space. The two sets of centering members 160 are movable, which can adapt to vehicles of different widths, ensuring that both small and large vehicles can be accurately parked in the center of the parking space. By automatically adjusting the position of the centering members 160, the system can autonomously complete the vehicle guidance and centering operation, reducing manual intervention and improving parking efficiency.

[0110] Optionally, the centering member 160 is constructed as a rod-like structure extending along the length direction DL, and two sets of centering members 160 are parallel.
