It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0042] like Figure 1-7 As shown, an electric aircraft battery 8 replacement device includes a trolley 1, a lifting structure 2, an angle adjustment structure 3, a sliding plate 4 and a battery 8;

[0043] The lifting structure 2 is fixed on the trolley 1. The function of the lifting structure 2 is to provide stable support and lifting function for the equipment thereon so that it can adapt to battery compartments of different heights;

[0044] The angle adjustment structure 3 is fixed to the top of the lifting structure 2, and one side of the bottom of the increasing slide plate 4 is connected to the lifting structure 2. Specifically, a rotating shaft is arranged on the right side of the adjusting increasing slide plate 4, and both ends of the rotating shaft are rotatably mounted on the top of the lifting structure 2 through a bearing seat; the other side of the increasing slide plate 4 is supported by the angle adjustment structure 3; when the angle adjustment structure 3 is tilted up, the left side of the increasing slide plate 4 is driven to rise, and the increasing slide plate 4 is driven to rotate upward, thereby adjusting the angle of the increasing slide plate 4;

[0045] The battery 8 is placed on the increasing slide plate 4. The front end of the increasing slide plate 4 is not a flat structure but an angled structure. The setting of the angle at the front end of the increasing slide plate 4 is to fit the shape of the opening position of the battery compartment of the electric aircraft. In actual use, since the opening position of the battery compartment of the electric aircraft is not flat but has an angle, the setting of the angle at the front end of the increasing slide plate 4 can better fit the opening of the battery compartment.

[0046] Furthermore, the angle adjustment structure 3 includes a lever arm 6, a pressure plate 11, a lever arm adjustment stage 7 and a first hydraulic hand pump 10;

[0047] The lever arm adjustment platform 7 is fixed to the left side of the top of the lifting structure 2 and is used to install the first hydraulic hand pump 10 and the pressure plate 11; the lever arm adjustment platform 7 provides installation and adjustment support for the first hydraulic hand pump 10 and the pressure plate 11, so that they can work stably.

[0048] The first hydraulic hand pump 10 is fixed on the upper part of the lever arm adjustment platform 7, and its output end passes downward through the top plate of the lever arm adjustment platform 7 and is connected to the pressing plate 11, and the pressing plate 11 is driven to move up and down by the first hydraulic hand pump 10;

[0049] The pressing plate 11 is a plate-like structure, and its lower surface is in contact with the left end of the lever arm 6;

[0050] The lever arm 6 is fixed to the top of the lifting structure 2 and is used to adjust the angle of the increasing slide plate 4; the middle part of the lever arm 6 is hinged to the top of the lifting structure 2; the left end of the lever arm 6 contacts the bottom of the pressure plate 11, and the right end of the lever arm 6 contacts the bottom of the increasing slide plate 4.

[0051] When in use, the first hydraulic hand pump 10 drives the pressing plate 11 to move downward, and the pressing plate 11 presses the left end of the lever arm 6 downward, and at this time, the right end of the lever arm 6 tilts upward.

[0052] Further, the lever arm 6 includes an active arm, a driven arm and a transmission shaft;

[0053] The transmission shaft is arranged in the middle of the lever arm 6; the active arm is arranged on the left side of the transmission shaft, and the driven arm is fixed on the right side of the transmission shaft, and there is a certain angle between the active arm and the driven arm;

[0054] Both ends of the transmission shaft are installed on the top of the angle adjustment structure 3 through the bearing seat, and the transmission shaft and the bearing seat are hinged;

[0055] The top of the active arm contacts the bottom of the pressure plate 11 , and the top of the passive arm contacts the bottom of the increasing slide plate 4 .

[0056] In actual use, since the active arm, the driven arm and the transmission shaft form a lever structure, the length of the active arm is generally set to be greater than the length of the driven arm so as to form a labor-saving lever structure;

[0057] Furthermore, pulleys are provided at the top of the active arm and the passive arm; the pulley at the top of the active arm contacts the bottom of the pressure plate 11, and the pulley at the top of the passive arm contacts the bottom of the increasing slide plate 4; in the initial state, the increasing slide plate 4 is in a horizontal state, and the first hydraulic hand pump 10 drives the pressure plate 11 to move up and down, and the pressure plate 11 presses the pulley at the top of the active arm downward, at this time, the right end of the lever arm 6 is tilted upward, and the left side of the increasing slide plate 4 is pushed upward through the pulley at the top of the passive arm, thereby adjusting the angle of the increasing slide plate 4.

[0058] Furthermore, a limiting structure 5 is also provided on the increasing slide plate 4. In the present embodiment, the limiting structure 5 is a clamping structure. Specifically, there are two limiting structures 5, which are symmetrically fixed on both sides of the increasing slide plate 4 in the length direction. Each limiting structure 5 is a clamping plate with a threaded rod, and the clamping plate is threadedly connected to the increasing slide plate 4 through the threaded rod. The clamping plate is driven close to the battery 8 by rotating the threaded rod; thereby clamping and fixing the left and right sides of the electric aircraft battery 8, ensuring that the battery 8 will not shift or shake during transportation, thereby ensuring the safe transportation of the battery 8.

[0059] Furthermore, the increase slide plate 4 is also provided with rollers 9; the rollers 9 are installed at the front of the increase slide plate 4, and are used to smoothly move the electric aircraft battery 8, so as to facilitate its installation in the electric aircraft battery compartment. The rollers 9 are installed at the front end of the increase slide plate 4, and there are four rows of rollers 9, each row is equipped with two rollers 9, and the corresponding increase slide plate 4 can realize the placement of up to four batteries 8 at the same time.

[0060] Furthermore, the trolley 1 comprises a base 101 , a handle 102 and wheels 103 ;

[0061] The upper part of the base 101 is provided with a lifting structure 2 and an angle adjustment structure 3 to provide a stable foundation for the entire device.

[0062] The handle 102 is disposed on the rear side of the base 101 and is used to push the battery 8 installation device forward, making it convenient for the operator to control the moving direction of the device.

[0063] The wheels 103 are installed at the bottom of the base 101. The wheels 103 have four parts, two fixed wheels and two universal wheels. The fixed wheels are used to move in a certain direction to ensure the stability of the device when driving in a straight line, and the universal wheels are used to move in any direction, so that the device can flexibly turn and adjust its position.

[0064] Furthermore, a protective rod 13 is provided under the handle 102, and the protective rod 13 is located on the rear side of the enhancing slide plate 4. When the battery 8 is placed on the enhancing slide plate 4, the protective rod 13 is located on the rear side of the battery 8, which can limit the position of the rear side of the battery 8 to prevent the battery 8 from moving backward during transportation; in actual use, the protective rod 13 can also be replaced by a plate-shaped protective plate, which can also protect the rear side of the battery 8 to prevent foreign objects from colliding with the rear side of the battery 8.

[0065] Furthermore, the material of the reinforcing plate 4 is polytetrafluoroethylene, which is used to reduce the friction coefficient. Polytetrafluoroethylene has excellent wear resistance and low friction coefficient, which can effectively reduce the friction between the battery 8 and the reinforcing plate 4, making the movement of the battery 8 smoother.

[0066] Furthermore, the lifting structure 2 is a scissor lift, and a second hydraulic hand pump 12 is provided on the lifting structure 2. The second hydraulic hand pump 12 can be used manually in the absence of power supply or other power sources, and the lifting structure 2 can be lifted and lowered by extending and retracting the second hydraulic hand pump 12.

[0067] Working principle:

[0068] The lifting structure 2 provides lifting power through the second hydraulic hand pump 12 to realize the lifting function of the equipment to adapt to battery compartments of different heights and accurately deliver or remove the battery 8 from the battery compartment.

[0069] The angle adjustment structure 3 adjusts the angle of the increase slide plate 4 through the coordinated action of the lever arm 6, the pressure plate 11, the force arm adjustment stage 7 and the first hydraulic hand pump 10. The first hydraulic hand pump 10 drives the pressure plate 11 to move up and down, and the pressure plate 11 presses the left end of the lever arm 6 downward, so that the right end of the lever arm 6 tilts upward. The lever arm 6 pushes the left side of the increase slide plate 4 upward through the pulley at the top of the movable arm, thereby adjusting the increase slide plate 4 to rotate upward, and realizing the adjustment of the angle of the increase slide plate 4 to adapt to the tilt angle of the bottom of the battery compartment.

[0070] Usage process:

[0071] First, the electric aircraft battery 8 is placed on the increasing slide plate 4, and the position of the battery 8 is fixed by the limiting structure 5. The operator pushes the installation device by the handle 102 to move it to the vicinity of the opening of the electric aircraft battery compartment.

[0072] Then, according to the height of the battery compartment, the second hydraulic hand pump 12 on the lifting structure 2 is operated to extend and retract the second hydraulic hand pump 12, thereby adjusting the height of the increasing slide plate 4 to adapt it to the height of the battery compartment.

[0073] Then operate the first hydraulic hand pump 10 to drive the pressing plate 11 to move up and down. The pressing plate 11 presses the left end of the lever arm 6 downward, so that the right end of the lever arm 6 tilts upward, thereby driving the left side of the increasing slide plate 4 to rise, and adjusting the angle of the increasing slide plate 4 to make it consistent with the entrance angle of the battery compartment.

[0074] Finally, when the height and angle of the increasing slide plate 4 are adjusted appropriately, the battery 8 can be smoothly moved into or taken out of the battery compartment by the action of the roller 9 .
