[0030] Please refer to Figure 1-Figure 3The embodiment of the utility model provides an intelligent leveling foot cup system, including a shell 5, a foot cup assembly, a caster assembly and a mounting plate 13. The foot cup assembly includes a foot cup 12, a lifting support column 11, a motor drive module, and a control module 10; the foot cup 12 is fixed to one end of the lifting support column 11; the motor drive module drives the lifting support column 11 to reciprocate and then drives the foot cup 12 to reciprocate; the lifting support column 11, the motor drive module, and the control module 10 are located inside the shell 5, and the lifting support column 11 extends downward through the bottom of the shell 5 and can reciprocate in the shell 5; a POM guide ring 9 is also provided inside the shell 5, and the POM guide ring 9 surrounds the lifting support column 11 outer wall is set; the control module 10 includes at least one height sensor or angle sensor, which is used to detect the height or angle position information of the current foot cup, so that the control module can adjust the position of the foot cup according to the height or angle position information to achieve fast and accurate adjustment of the foot cup position; the motor drive module includes a drive motor 7, a drive gear (not shown in the figure) connected to the output shaft of the drive motor 7, a reduction gear 3 matched with the drive gear, a screw rod 2, and a lifting screw nut 8. The end of the output shaft is fixed and limited by a first bearing 1. Specifically, the number of teeth of the drive gear is 15, and the number of teeth of the reduction gear 3 is 30. In addition, the drive The driving motor 7 is arranged in an inverted manner, with the driving shaft arranged upward, and the driving motor 7 body and the lifting support column 11 are arranged in parallel, which can reduce the overall height of the intelligent leveling foot cup system to a certain extent, making the entire set of mechanism structures arranged compactly, enhancing the transmission efficiency, and also saving installation space; the reduction gear 3 is fixedly connected to the screw rod 2, and specifically, the reduction gear 3 and the screw rod 2 can be fixedly connected by a conventional interference fit; the lifting nut 8 is rotatably connected to the screw rod 2, and the screw rod 2 is preferably a trapezoidal screw rod structure. Due to the special properties of the thread of the trapezoidal screw rod, the pitch is greater than the thread friction angle, the slope is less than the friction angle, and the friction coefficient is large enough to enable the nut to stop rotating when the screw rod stops rotating. At this time, the trapezoidal lead screw will self-lock and the nut will be limited to the current position. As long as the lead screw remains stationary, the nut will be locked; the caster assembly includes a caster 17, a universal shaft 16, and a caster pad 15. The caster 17 and the caster pad 15 are connected by the universal shaft 16, so that the caster can move in multiple directions; the foot cup assembly and the caster assembly are installed side by side on the mounting plate 13. When the lifting support column 11 retracts upward to the original position, the height of the lifting support column 11 will be lower than the height of the caster 17, forming a height difference, and the caster touches the ground and can roll freely. When the lifting support column 11 extends forward to the extreme position, the height is higher than the caster 17, and the caster 17 will be suspended in the air, and the foot cup 12 supports the ground.

[0031] In a possible embodiment, the lifting support column 11 adopts a hollow structure, and the screw rod 2 is at least partially located inside the hollow structure. By using the lifting support column 11 with a hollow structure to cooperate with the movement of the screw rod 2, the overall height of the intelligent leveling foot cup system can be further reduced. The screw rod includes a threaded section and a non-threaded section, and the reduction gear 3 is passed through the non-threaded section. The non-threaded section is fixed and limited by the second bearing 4. The lifting nut is passed through the threaded section and fixed to the other end of the lifting support column 11. The lifting support column 11 is fixedly connected to the lifting nut 8. When moving, the lifting nut 8 will drive the lifting support column 11 to move up and down to achieve a lifting action. Preferably, the lifting nut 8 is embedded in the hollow structure at the other end of the lifting support column 11, which can further reduce the overall height of the mechanism and make the entire set of mechanism structure layout more compact.

[0032] In a possible implementation, an intermediate transmission gear (not shown) is further included, which is respectively connected to the driving gear and the reduction gear 3. The driving gear and the reduction gear are reduced in speed through the intermediate transmission gear. Preferably, the intermediate transmission gear has 20 teeth.

[0033] In a possible implementation, a limit device is provided at each limit of the up and down movement of the lifting nut 8, and the limit device limits the displacement of the lifting nut 8. Preferably, the limit device is a limit sensor 6, and when the lifting nut 8 triggers the limit sensor 6, the control module controls the motor drive module to stop moving. Specifically, the lifting nut 8 triggers the physical button of the limit sensor 6 to cut off the power of the motor, so that the motor drive module stops moving.

[0034] In a possible implementation, the control module 10 further includes a program control unit and a storage unit. The program control unit can control the motor to rotate forward, reverse, stop rotating, or adjust the speed; the storage unit is used to store the current height data and angle data of the foot cup. The sensor is one or more of an inclination sensor, an angle sensor, and a gyroscope sensor. The sensor can detect the current height, angle, and other position information of the foot cup, and the control module 10 can store the detected position information.

[0035] In another embodiment, a device using the above-mentioned intelligent leveling foot cup system is also provided, the device includes at least two intelligent leveling foot cup systems, and the device also includes a human-computer interaction module, the human-computer interaction module is connected to the control module, and the human-computer interaction module can realize the rapid adjustment of the height, angle or horizontality of the device according to the foot cup height data or angle data stored in the storage unit. Specifically, the human-computer interaction module can be a physical button or touch screen set on the device, or it can be a mobile terminal, and the mobile terminal is connected to the control module through WIFI, Bluetooth, data cable, etc., and the mobile terminal can be a handle, mobile phone, tablet, computer, remote control, etc.

[0036] The human-computer interaction module receives the operator's instructions and transmits the instructions to the control module 10. The control module 10 receives and processes the instruction information, identifies the instruction function through the program and executes the functional instruction, and sends the instruction to the motor drive module. The motor drive module outputs an electrical signal according to the instruction, and then outputs the electrical signal to the motor 7 through the amplification module to realize the forward rotation, reverse rotation, stop rotation or speed adjustment of the motor 7, thereby controlling the foot cup 12 to realize the automatic lifting function.

[0037] When it is necessary to realize intelligent leveling of the equipment, one-button leveling can be achieved through the human-computer interaction module. Specifically, the control module 10 converts the command signal received by the human-computer interaction module into a digital signal, controls the cooperation between the multiple foot cups 12 through the angle and height data detected by the sensor, intelligently adjusts the motor output of each intelligent level foot cup system, and finally adjusts the equipment to a horizontal state.

[0038] Similarly, through the human-computer interaction module, the device can also realize the synchronous lifting and lowering adjustment function of multiple foot cups 12 and the specified height adjustment function, etc.; in addition, the control module 10 has a position memory function. When it is necessary to quickly adjust to the previous position, the human-computer interaction module and the control module 10 can realize the rapid resetting adjustment of the foot cup.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
