[0034] The transverse vehicle platform drive group includes a plurality of vehicle platform drive systems 2 arranged at intervals in sequence along the transverse movement direction of the vehicle platform body 1, and the longitudinal vehicle platform drive group includes a plurality of vehicle platform drive systems 2 arranged at intervals in sequence along the longitudinal movement direction of the vehicle platform body 1; an import and export 4 communicating with the stage foundation pit is arranged on the stage surface 3, and each import and export 4 corresponds to the vehicle platform drive system 2 one by one; when the vehicle platform body 1 needs to move transversely, the vehicle platform drive systems 2 in the transverse vehicle platform drive group sequentially extend out of the import and export 4 to be in contact connection with the vehicle platform body 1, and relay to drive it to move in the transverse direction; when the vehicle platform body 1 needs to move longitudinally, the vehicle platform drive systems 2 in the longitudinal vehicle platform drive group sequentially extend out of the import and export 4 to be in contact connection with the vehicle platform body 1, and relay to drive it to move in the longitudinal direction. When the vehicle platform body 1 is converted from transverse movement to longitudinal movement, the transverse vehicle platform drive group is hidden in the stage foundation pit, and when the vehicle platform body 1 is converted from longitudinal movement to transverse movement, the longitudinal vehicle platform drive group is hidden in the stage foundation pit.

[0035] Specifically, multiple sets of transverse vehicle platform drive groups can be arranged at intervals in sequence along the longitudinal movement direction of the vehicle platform body 1 according to the length of the stage surface 3, and each transverse vehicle platform drive group includes a plurality of vehicle platform drive systems 2 arranged at intervals in sequence along the transverse movement direction of the vehicle platform body 1. As shown in Figure 1, there are two sets of transverse vehicle platform drive groups. Multiple sets of longitudinal vehicle platform drive groups can be arranged at intervals in sequence along the transverse movement direction of the vehicle platform body 1 according to the width of the stage surface 3, and each longitudinal vehicle platform drive group includes a plurality of vehicle platform drive systems 2 arranged at intervals in sequence along the longitudinal movement direction of the vehicle platform body 1. As Figure 1 shown, only one set of longitudinal vehicle platform drive group is arranged considering the width of the stage. The vehicle platform drive systems 2 included in each group can be set according to the actual situation to better meet the actual needs.

[0036] 1. Vehicle platform body

[0037] In this embodiment, the vehicle platform body 1 includes a body structure 11, a transverse rack 15, a longitudinal rack 14, a rack cross plate 13, and a walking wheel assembly 12.

[0038] The body structure 11 is composed of steel sections welded into a rectangular frame structure, and the transverse rack 15, the longitudinal rack 14, the rack cross plate 13, and the walking wheel assembly 12 are welded to its lower surface.

[0039] As Figure 2 and Figure 3 shown, two sets of walking wheel groups are arranged at intervals along the width direction of the lower surface of the body structure 11. Each walking wheel group includes a plurality of walking wheel assemblies 12 arranged at intervals in sequence along the length direction parallel to the body structure 11. The walking wheel assembly 12 includes a top plate 121, a bottom plate 122, and a walking wheel 123. The top plate 121 is fixedly connected to the body structure 11. The bottom plate 122 is rotatably connected to the lower part of the top plate 121 through a silent bearing, and the walking wheel 123 is rotatably connected to the lower part of the bottom plate 122 through a silent bearing.

[0040] The top plate 121 and the bottom plate 122 are connected by a bearing, and the bottom plate 122 and the walking wheel 123 are connected by a bearing. In this way, when the vehicle platform body 1 makes a vertical direction change, the walking wheel 123 can move forward along the traveling direction of the vehicle platform body 1. In the stage industry, there are high requirements for sound decibels, and silent bearings can reduce decibels to a certain extent. At the same time, the walking wheel 123 is made of silica gel material to further ensure that noise is reduced during the movement of the vehicle platform body 1 to meet the requirements of the stage industry for decibels.

[0041] At least two transverse racks 15 (as Figure 2 shown, there are multiple transverse racks 15) are arranged at intervals in sequence along the length direction parallel to the body structure 11 on the lower surface of the body structure 11, and at least two longitudinal racks 14 (as Figure 2 shown, there are two longitudinal racks 14) are arranged at intervals in sequence along the width direction parallel to the body structure 11. The transverse rack 15 extends along the width direction parallel to the body structure 11, and the longitudinal rack 14 extends along the length direction parallel to the body structure 11. The transverse rack 15 and the longitudinal rack 14 are arranged perpendicular to each other.

[0042] A rack cross plate 13 is arranged at the intersection of the transverse rack 15 and the longitudinal rack 14. The rack cross plate 13 is fixedly connected to the lower surface of the body structure 11, and the intersection of the transverse rack 15 and the longitudinal rack 14 is fixedly connected to the side of the rack cross plate 13 away from the body structure 11. The rack cross plate 13 enables the transverse rack 15 and the longitudinal rack 14 to form a complete rack structure in their respective directions.

[0043] The traveling wheel assembly 12 contacts the stage surface 3. When the stage body 1 needs to move horizontally, the stage driving system 2 in the horizontal stage driving group sequentially extends out of the inlet / outlet 4 and is connected with the horizontal rack 15 in a matching manner to drive the stage body 1 to move horizontally; when the stage body 1 needs to move longitudinally, the stage driving system 2 in the longitudinal stage driving group sequentially extends out of the inlet / outlet 4 and is connected with the longitudinal rack 14 in a matching manner to drive the stage body 1 to move longitudinally.

[0044] In order to ensure the traveling direction of the stage body 1, guide plate structures can be installed on both sides of the rack, and the moving direction of the stage body 1 is restricted through the guide plate structures to avoid deflection.

[0045] 2. Stage driving system

[0046] In this embodiment, as Figure 4 shown, the stage driving system 2 includes a driving mechanism 21, a driving telescopic mechanism 22, a cover plate mechanism 23, a driving inner frame 24 and a limiting mechanism.

[0047] The driving inner frame 24 is arranged in the stage foundation pit. The driving mechanism 21 is hinged to the driving inner frame 24. The telescopic end and the fixed end of the driving telescopic mechanism 22 are respectively fixedly connected to the driving mechanism 21 and the driving inner frame 24. The driving telescopic mechanism 22 extends or contracts, and then drives the driving mechanism 21 to rotate around its hinge point with the driving inner frame 24, so that the driving mechanism 21 extends out of the inlet / outlet 4 and is connected with the stage body 1 in a matching manner to drive the stage body 1 to move, or disconnects from the stage body 1 and retracts into the inlet / outlet 4.

[0048] The cover plate mechanism 23 is connected to the driving inner frame 24 and the driving mechanism 21. When the driving mechanism 21 descends under the action of the driving telescopic mechanism 22, the cover plate mechanism 23 flips and closes; when the driving mechanism 21 ascends under the action of the driving telescopic mechanism 22, the cover plate mechanism 23 flips and opens, and the driving mechanism 21 is connected with the stage body 1 in a matching manner to drive the stage body 1 to move.

[0049] The limiting mechanism is used to limit the up and down movement position of the driving mechanism 21 to ensure the connection between the driving mechanism 21 and the stage body 1 and the switching state of the cover plate mechanism 23.

[0050] In this embodiment, one end of the driving mechanism 21 is connected to the driving inner frame 24 by a hinge shaft, and the other end is connected to the driving telescopic mechanism 22 by a pin shaft to form a hinged structure. The other end of the driving telescopic mechanism 22 is fixedly connected to the driving inner frame 24. Under the action of the electric push rod 223 in the driving telescopic mechanism 22, the driving mechanism 21 can rotate along the hinge shaft connected to the driving inner frame 24, so as to realize the lifting of the gear 215. The cover plate frame 231 in the cover plate mechanism 23 is fixedly connected to the driving inner frame 24 to form a stable support structure. One end of the cover plate 234 is hinged to the cover plate frame 231, and the other end is connected to the connecting pipe 232 through a crank-rocker structure formed by a connecting rod 235 and a crank 236. A spring 233 is connected between the crank 236 and the driving inner frame 24, and the connecting pipe 232 is in soft tangential connection with the gear shaft 217 in the driving mechanism 21. When the electric push rod 223 in the driving telescopic mechanism 22 pushes the driving mechanism 21 to rise, the gear shaft 217 in the driving mechanism 21 relaxes the pressing on the connecting pipe 232, the spring 233 contracts, and the cover plate 234 is driven to open through the crank-rocker structure. At the same time, the gear 215 rises. Similarly, when the electric push rod 223 in the driving telescopic mechanism 22 contracts and drives the driving mechanism 21 to descend, the gear shaft 217 in the driving mechanism 21 presses on the connecting pipe 232, pulls the spring 233, drives the cover plate 234 to close through the crank-rocker structure, and at the same time the gear 215 descends and hides into the driving inner frame 24. After the cover plate 234 is closed, it and other decorative structures jointly form the stage surface.

[0051] 2.1. Driving mechanism

[0052] As Figure 5 shown, the driving mechanism 21 includes a motor reducer 211, a reducer mounting seat 212, a gear shaft 217, a gear 215, a hub 214, a hinge shaft 216 and an encoder 213. The gear 215 is used to mesh with the rack. The gear 215 is fixedly connected to the hub 214. The hub 214 is fixedly connected to the gear shaft 217. The gear shaft 217 is connected to the output shaft of the motor reducer 211. The motor reducer 211 is installed on the reducer mounting seat 212. The reducer mounting seat 212 is connected to the driving inner frame 24 through the hinge shaft 216. Encoders 213 are arranged on both the gear shaft 217 and the output shaft of the motor reducer 211. The motor reducer 211 is fixedly connected to the driving telescopic mechanism 22.

[0053] The gear 215 is made of nylon material to ensure that there will be no significant noise when the gear 215 meshes with the rack. The gear 215 and the hub 214 are connected by bolts, and the hub 214 and the gear shaft 217 are connected by a key. The gear shaft 217 passes through the shaft hole on the motor reducer 211 and is fixedly connected to the output shaft of the motor reducer 211. The motor reducer 211 is installed on the reducer mounting seat 212 by bolts. Another mounting surface of the motor reducer 211 is fixedly connected to the push rod seat 221 in the drive telescopic mechanism 22 by bolts. After the above connections, the drive mechanism 21 forms a stable hinge structure to ensure the lifting of the gear 215. The encoder 213 is connected to the control end and transmits relevant data to the control end. Through the control end, the displacement and position of the vehicle platform body 1 can be clearly known.

[0054] 2.2. Drive Telescopic Mechanism

[0055] As Figure 6 shown, the drive telescopic mechanism 22 includes a push rod seat 221, a slider 222, an electric push rod 223, a hinge seat 224, and a shock-absorbing fastener 225. The push rod seat 221 is fixedly connected to the motor reducer 211. The telescopic end of the electric push rod 223 is hinged to the push rod seat 221, and the fixed end of the electric push rod 223 is connected to the hinge seat 224. The hinge seat 224 is fixedly connected to the drive inner frame 24 by bolts through the shock-absorbing fastener 225. The slider 222 is installed on the push rod seat 221 by bolts. The telescopic end of the electric push rod 223 drives the drive mechanism 21 to move up and down in the drive inner frame 24, so that the gear 215 extends out of the inlet and outlet 4 to mesh with the rack to drive the vehicle platform body 1 to move, or disengages from the rack to retract the inlet and outlet 4.

[0056] 2.3. Cover Plate Mechanism

[0057] As Figure 7 shown, the cover plate mechanism 23 includes a cover plate frame 231, a cover plate 234, a crank-link mechanism, a spring 233, and a connecting pipe 232. The cover plate frame 231 is fixedly connected to the drive inner frame 24 by bolts to form a stable support structure. One end of the cover plate 234 is hinged to the cover plate frame 231, and the other end is connected to the crank-link mechanism. The crank-link mechanism is connected to the connecting pipe 232. One end of the spring 233 is connected to the crank 236 of the crank-link mechanism, and the other end is connected to the drive inner frame 24.

[0058] When the driving mechanism 21 descends under the action of the electric push rod 223, the gear shaft 217 presses the connecting pipe 232, the spring 233 stretches, and drives the cover plate 234 to flip and close the inlet and outlet 4 through the crank connecting rod assembly. When the driving mechanism 21 ascends under the action of the electric push rod 223, the gear shaft 217 releases the pressing on the connecting pipe 232, the spring 233 contracts, and the cover plate 234 is flipped open the inlet and outlet 4 through the crank connecting rod assembly. The gear 215 rises and meshes with the rack, and then drives the vehicle platform body 1 to move.

[0059] 2.4. Limit mechanism

[0060] As Figure 4 shown, the limit assembly includes a limit bumper 26 and a limit switch 25. The limit bumper 26 is installed on the driving assembly, and the limit switch 25 is installed on the driving inner frame 24. The limit bumper 26 ensures the upper and lower limit positions of the driving assembly by touching the upper and lower limit switches 25.

[0061] 2.5. Driving inner frame

[0062] As Figure 8 shown, the driving inner frame 24 includes a support frame 241 and a guide plate assembly 242. The support frame 241 is a structural frame welded and spliced by profiled steel, and is the support structure of the entire vehicle platform driving system 2. The driving mechanism 21, the driving telescopic mechanism 22, the cover plate mechanism 23 and the limit mechanism are all installed on the support frame 241. The support frame 241 is provided with mounting holes for installing the hinge shaft 216, mounting holes for installing the hinge shaft 216 seat, and a connecting plate for connecting the cover plate mechanism 23.

[0063] The guide plate assembly 242 is connected to the inner frame by bolts. The guide plate assembly 242 is used to limit the displacement of the slider 222, so as to ensure the moving direction of the driving mechanism 21.
