This forces operators to manually adjust the installation angle and position of the battery compartments, making the installation process cumbersome and complex. Furthermore, it increases the risk of installation errors due to human error, affecting the reliability of the battery compartment installation. Summary of the Invention

A handle 611 is provided on the main connecting rod 61, and the operator can pull the installation vehicle by holding the handle 611 and using the steering mechanism 6.

[0041] Furthermore, by setting the steering mechanism 6, the connection stability between the main connecting rod 61 and the installation vehicle can be improved, while also facilitating the control of the movement direction of the installation vehicle.

[0042] Specifically, the lifting mechanism 2 includes a scissor fork linkage, which includes a first link, a second link, a third link, and a fourth link. The middle positions of the first link and the second link are rotatably connected by a pivot, thereby allowing the first link and the second link to cross-fit together to form a first link group.

[0045] Specifically, Figure 4 A schematic diagram of the structure of a turbine screw jack 72 according to an embodiment of the present invention is shown. A turbine screw jacking mechanism 5 is arranged axially along the X-axis on the chassis 1. The turbine screw jacking mechanism 5 includes a handle, a transmission screw 51, and a nut slider 52. The transmission screw 51 is disposed between the first slide groove 12 and the second slide groove 13. The nut slider 52 is sleeved on the transmission screw 51 and is threadedly connected to the transmission screw 51. The middle position of the movable shaft 14 is fixed on the nut slider 52. The handle is driven and connected to the transmission screw 51. The handle is disposed on the side wall of the chassis 1. By rotating the handle, the transmission screw 51 is driven to rotate, so that the nut slider 52 moves on the transmission screw 51. The movable shaft 14 can move on the transmission screw 51 with the nut slider 52.

[0046] Furthermore, the movable shaft 14 can restrict the rotation of the nut slider 52, ensuring that the nut slider 52 moves on the transmission screw 51 as the transmission screw 51 rotates.

[0047] Specifically, the turbine screw lifting mechanism 5 is also equipped with an electric drive component, which drives and connects to the transmission screw 51. The electric drive component can drive the transmission screw 51 to rotate, thereby realizing the movement of the nut slider 52 on the transmission screw 51. This enables high-load and rapid lifting movements, saving the manual labor costs required for the operation of the turbine screw.

[0048] Furthermore, the worm gear screw lifting mechanism 5 can drive the movable shaft 14 to move between the first slide groove 12 and the second slide groove 13, thereby driving the first connecting rod and the third connecting rod to move, causing the first connecting rod group and the second connecting rod group to retract towards the Z-axis, so that the scissor fork connecting rod drives the top frame 3 to rise, or drives the first connecting rod group and the second connecting rod group to retract towards the X-axis, so that the scissor fork connecting rod drives the top frame 3 to descend.

[0049] Furthermore, through the cooperation of the electric drive component and the handle, the worm gear screw lifting mechanism 5 can be rapidly raised and lowered under the drive of the electric drive component, and fine-tuned by adjusting the height using the handle. This improves both the convenience of the installation vehicle in adjusting the height of the battery compartment and the accuracy of the installation vehicle in adjusting the height of the battery compartment, thereby improving the reliability of the battery compartment installation.

[0050] Specifically, Figure 5 A schematic diagram of the top frame 3 structure in an embodiment of the present invention is shown. The top frame 3 includes a frame body, which includes a third support rod 31 and a fourth support rod 32 that are parallel to each other. The third support rod 31 and the fourth support rod 32 are connected by a crossbeam to form the frame body. A first base 37 and a second base 38 are provided on the third support rod 31, and a third base 39 and a fourth base 40 are provided on the fourth support rod 32. The first base 37, the second base 38, the third base 39, and the fourth base 40 are used to install the multifunctional platform 4.

[0051] Furthermore, a first friction pad 33 is provided on the third support rod 31, and the first friction pad 33 is located at the middle position between the first base 37 and the second base 38. A second friction pad 34 is provided on the fourth support rod 32, and the second friction pad 34 is located at the middle position between the third base 39 and the fourth base 40. The first friction pad 33 and the second friction pad 34 are used to increase the friction between the multifunctional base and the top frame 3.

[0052] Furthermore, the third support rod 31 is also provided with a first pin seat 35, and the fourth support rod 32 is provided with a second pin seat 36. The multi-functional platform 4 is fixed in the first pin seat 35 and the second pin seat 36 based on the pin 423, thereby improving the connection stability between the multi-functional platform 4 and the top frame 3.

[0053] Specifically, the bottom of the third support rod 31 is provided with a first track 311 and a third mounting base 312, the bottom of the fourth support rod 32 is provided with a second track 321 and a fourth mounting base 322, the top end of the second connecting rod is slidably engaged in the first track 311, the top end of the first connecting rod is rotatably engaged in the third mounting base 312, the top end of the fourth connecting rod is slidably engaged in the second track 321, and the top end of the third connecting rod is rotatably engaged in the fourth mounting base 322.

[0054] Furthermore, when the scissor fork linkage drives the top frame 3 to move up and down, the bottom end of the first linkage moves within the first slide groove 12, the bottom end of the third linkage moves within the second slide groove 13, the second linkage moves within the first track 311, and the fourth linkage moves within the second track 321, thereby realizing the retraction and extension operation of the scissor fork linkage, thereby driving the top frame 3 to move up and down.

[0055] Specifically, several ball-type rolling devices are evenly arranged on the first base 37, the second base 38, the third base 39, and the fourth base 40. The mobile platform 42 is placed on the ball-type rolling devices. The mobile platform 42 includes a mobile base plate, a first bracket and a second bracket arranged on the mobile base plate. The first bracket and the second bracket are symmetrically arranged at both ends of the mobile base plate. The first bracket and the second bracket are used to support the battery compartment.

[0056] Specifically, Figure 6 A schematic diagram of the structure of the multifunctional platform 4 in an embodiment of the present invention is shown. Figure 7 A schematic diagram of the rotating state structure of the mobile platform 42 in an embodiment of the present invention is shown. A first friction device 421 and a second friction device 422 are symmetrically arranged on both sides of the mobile base plate. The first friction device 421 is correspondingly arranged at the position of the first friction pad 33, and the second friction device 422 is correspondingly arranged at the position of the second friction pad 34.

The threaded pressure rod 4212 presses against the first friction pad 33. By rotating the adjusting handwheel 4211, the contact pressure between the threaded pressure rod 4212 and the first friction pad 33 can be adjusted, thereby adjusting the friction between the movable platform 42 and the top frame 3, so as to adjust the position of the movable platform 42 in the XY plane.

[0058] Furthermore, the second friction device 422 has the same structural features and functional effects as the first friction device 421, which will not be described in detail here.

[0059] Specifically, the mobile platform 42 is provided with two pins 423, which are respectively inserted into the first pin seat 35 and the second pin seat 36. When the multi-functional platform 4 is in an idle state, the multi-functional platform 4 is fixed to the top frame 3 based on the pins 423.

[0060] Furthermore, when the operator needs to adjust the position of the multi-functional platform 4, the latch 423 can be loosened to adjust the position of the multi-functional platform 4. After the position adjustment of the multi-functional mobile platform 42 is completed, the friction force between the mobile platform 42 and the top frame 3 can be adjusted by the first friction device 421 and the second friction device 422, so that the mobile platform 42 is fixed on the top frame 3, thereby fixing the position of the multi-functional platform 4.

[0061] Furthermore, the first base 37, the second base 38, the third base 39 and the fourth base 40 of the top frame 3 are each provided with a first limiting block. The first limiting block is used to restrict the movement position of the mobile platform 42 and prevent the mobile platform 42 from slipping off the top frame 3.

[0062] Furthermore, the first friction pad 33 and the second friction pad 34 are provided with second limiting blocks, which are correspondingly provided in the hollow area inside the movable platform to prevent the movable platform 42 from sliding off the side of the top frame 3.

[0063] Furthermore, an operating handle 424 is provided on the movable base plate. After the operator releases the pin 423, the friction between the movable platform and the top frame 3 can be adjusted by the first friction device 421 and the second friction device 422. By holding the operating handle 424, the operator can push the movable platform 42, so that the movable platform 42 moves on the rolling platform 41, thereby adjusting the position and posture of the multifunctional platform 4.

[0064] Specifically, Figure 8 A schematic diagram of the lifting device 7 structure in an embodiment of the present invention is shown. A plurality of lifting devices 7 are provided on the top frame 3, correspondingly positioned below the first base 37, the second base 38, the third base 39, and the fourth base 40.

By rotating the lifting handwheel 73, the lead screw inside the lifting mechanism 72 can be raised. The lead screw is connected to the ball-type rolling device, thereby enabling the lifting device 7 to drive the multi-functional platform 4 to rise and fall.

[0065] Specifically, the lifting device 7 is also provided with a first connector 74, a self-aligning pad 75, and a second connector 76. The top end of the lead screw is disposed on the first connector 74. The first connector 74 is connected to the second connector 76 based on the self-aligning pad 75. The second connector 76 is connected to the ball rolling device of the multi-functional platform 4. That is, by rotating the lifting handwheel 73, the lead screw can be driven to rise and fall, thereby driving the multi-functional platform 4 to rise and fall based on the first connector 74 and the second connector 76.

[0066] Furthermore, by adjusting several of the lifting devices 7, the multifunctional platform 4 can adjust its pitch and orientation to meet the installation requirements of the battery compartment.

[0067] Specifically, this embodiment of the invention provides a multi-degree-of-freedom installation vehicle for an aircraft battery compartment.
