[0032] For further information, see Figure 4 and Figure 5 , the driving wheel 9 is located at the front of the transfer vehicle, and the guide wheel 8 is located at the rear of the transfer vehicle.

[0033] For further information, see Figure 3 A support frame is provided on the top of the transfer vehicle base shell 1, and an arc-shaped seat plate 13 is provided in the middle position of the support frame.

[0034] For further information, see Figure 3 An upper limb armrest 14 is provided near the top surface of the support frame.

[0035] In this embodiment, it includes a transfer vehicle base shell 1, an embedded structure shell 2, an inclined guide rail structure and a variable torque drive structure, and also includes a guide wheel 8 and a drive wheel 9. The drive wheel 9 (5-inch drive wheel 9) is installed on the left and right sides of the front of the transfer vehicle (high step part: length 120 mm, width 500 mm, height 150 mm), and the guide wheel 8 (2.5-inch guide wheel 8) is installed on the left and right sides of the rear of the transfer vehicle (low step part: length 380 mm, width 500 mm, height 90 mm). The embedded mechanism (external dimensions: length 300 mm, width 300 mm, height 60 mm) is installed in the middle part of the embedded structure shell 2; the small support wheel 7 is a 1-inch universal wheel; the variable torque electric push rod 10 is controlled by the controller

[0036] When the intelligent transport vehicle moves to the patient's bedside or the edge of the toilet, the curved seat plate 13 is located under the bed surface or the oval base of the toilet, allowing the transport vehicle to step over the bed surface or the toilet, making it easier for the patient or the nursing staff to place the patient on the transport vehicle while ensuring the balance of the vehicle body; when the intelligent transport vehicle is traveling on a smooth road, the embedded mechanism is hidden in the base of the transport vehicle; when the intelligent transport vehicle is traveling on an uneven road or crossing a 40 mm groove, the embedded mechanism extends as a third support leg to achieve the crossing function, and the variable torque electric linear actuator 10 and the controller ensure that the embedded mechanism operates reliably in various states;

[0037] Specifically:

[0038] When the intelligent transport vehicle moves to the patient's position, the rear of the transport vehicle approaches the patient and starts the variable torque electric push rod 10. The variable torque electric push rod 10 extends to drive the inclined slide rail 5 to extend along the extending direction of the inclined guide rail 4. When the variable torque electric push rod 10 extends, the inclined slide rail support frame 6 extends from the inside of the embedded structure shell 2 along the extending direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully extended, the small support wheel 7 touches the ground to ensure that the transport vehicle is always in a stable and balanced state during the subsequent process of moving the patient to the transport vehicle (avoiding At this time, the patient's upper arms are placed on the upper armrests 14 for support, and the patient's buttocks are seated on the curved seat 13. At the same time, the patient's feet are placed on the low step of the transfer vehicle (i.e., the top surface of the inclined slide rail support frame 6); conversely, when the torque-variable electric push rod 10 is retracted, the inclined slide rail support frame 6 is retracted from the outside of the embedded structure housing 2 along the extending direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully retracted, the small support wheel 7 is off the ground, and the transfer vehicle starts to move to the new target position;

[0039] When the intelligent transport vehicle runs to the new target device, the rear of the transport vehicle approaches the target device and starts the variable torque electric push rod 10. The variable torque electric push rod 10 extends to drive the inclined slide rail 5 to extend along the extension direction of the inclined guide rail 4. When the torque electric push rod 10 extends, the inclined slide rail support frame 6 extends from the inside of the embedded structure shell 2 along the extension direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully extended, the small supporting wheel 7 touches the ground to ensure that the patient is subsequently moved to the new device. During the entire moving process, the transport vehicle is always in a stable and balanced state (avoiding overturning). On the contrary, when the torque electric push rod 10 retracts, the inclined slide rail support frame 6 retracts from the outside of the embedded structure shell 2 along the extension direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully retracted, the small supporting wheel 7 leaves the ground, and the transport vehicle starts to run to the new target position;

[0040] When the intelligent transfer vehicle is traveling on an uneven road surface or crossing a groove within 40 mm, the rear of the transfer vehicle is close to the groove, and the variable torque electric push rod 10 can extend to drive the inclined slide 5 along the extension direction of the inclined guide rail 4. When the variable torque electric push rod 10 is extended, the inclined slide rail support frame 6 extends from the inside of the embedded structure shell 2 through the inclined slide rail 5 along the extension direction of the inclined guide rail 4. After the inclined slide rail support frame 6 is fully extended, the small support wheel 7 touches the ground. At this time, the driving wheel 9 (5-inch driving wheel 9) and the small support wheel 7 (small support wheel 7) touch the ground on both sides of the groove and bear the force. The intelligent transfer vehicle starts the driving wheel 9 (5-inch driving wheel 9) and moves the transfer vehicle to the opposite side of the groove, realizing the function of crossing the groove.

[0041] For further information, see Figure 4 and Figure 5 Two driving wheels 9 are arranged on the base shell 1 of the transfer vehicle.

[0042] For further information, see Figure 4 and Figure 5 Two relatively distributed guide wheels 8 are also provided on the base shell 1 of the transfer vehicle, and the two driving wheels 9 and the two guide wheels 8 are distributed in a matrix.

[0043] In this embodiment, the driving wheel 9 is driven by the motor on the transfer vehicle, and the guide wheel 8 plays a guiding role. The driving wheel 9 and the guide wheel 8 cooperate to realize the movement of the transfer vehicle in any direction.

[0044] For further information, see Figure 5 When the variable torque electric push rod 10 is extended, the inclined slide rail support frame 6 extends from the inside of the embedded structure housing 2 along the extension direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully extended, the small support wheel 7 touches the ground.

[0045] For further information, see Figure 4When the variable torque electric push rod 10 retracts, the inclined slide rail support frame 6 retracts from the outside of the embedded structure housing 2 along the extending direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully retracted, the small support wheel 7 leaves the ground.

[0046] In this embodiment, when the intelligent transport vehicle moves to the patient's position, the rear of the transport vehicle approaches the patient and the variable torque electric push rod 10 is started. The variable torque electric push rod 10 extends to drive the inclined slide 5 to extend along the extension direction of the inclined guide rail 4. When the variable torque electric push rod 10 is extended, the inclined slide support frame 6 extends from the inside of the embedded structure shell 2 along the extension direction of the inclined guide rail 4 through the inclined slide 5. After the inclined slide support frame 6 is fully extended, the small support wheel 7 touches the ground, ensuring that the transport vehicle is always in a stable balance during the subsequent process of moving the patient to the transport vehicle state (to avoid overturning); at this time, the patient's upper arms are placed on the upper limb armrests 14, supported by the upper limb armrests 14, and the patient's buttocks sit on the curved seat 13. At the same time, the patient's feet are placed on the low step of the transfer vehicle (i.e., the top surface of the inclined slide rail support frame 6); on the contrary, when the torque-variable electric push rod 10 is retracted, the inclined slide rail support frame 6 is retracted from the outside of the embedded structure shell 2 along the extension direction of the inclined guide rail 4 through the inclined slide rail 5. After the inclined slide rail support frame 6 is fully retracted, the small support wheel 7 leaves the ground, and the transfer vehicle starts to move to the new target position.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
