In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1

[0035] Reference Figures 1 to 3 , is the first embodiment of the utility model, which provides a fixing mechanism that can achieve the effect of quick connection between the casing 102 and the wheel hub 201, including an installation unit 100, including a generator 101, a casing 102 arranged on one side of the generator 101, and a protective motor jacket 103 arranged on the outside of the generator 101; a connecting unit 200, including a wheel hub 201, a clamping assembly 202 arranged on the outside of the casing 102, a limiting assembly 203 arranged on the wheel hub 201, and the clamping assembly 202 and the limiting assembly 203 are adapted to each other.

[0036] Specifically, the clamping assembly 202 includes a connecting ring 202a disposed on the outside of the casing 102, a fixing block 202b disposed on the outside of the connecting ring 202a, and an extrusion surface 202c disposed on the fixing block 202b. The connecting ring 202a is disposed on the outside of the casing 102. The connecting ring 202a is in a circular ring shape, and a plurality of fixing blocks 202b are disposed on the outside thereof. The fixing block 202b is in a disc shape, and its edge is an arc surface, i.e., the extrusion surface 202c. A fixing ring 203a is disposed on one side of the hub 201. The fixing ring 203a is in a circular ring shape. The diameter of the connecting ring 202a is smaller than the diameter of the fixing ring 203a. The outer wall of the connecting ring 202a fits the inner wall of the fixing ring 203a. A plurality of movable The sheet 203b and the movable sheet 203b are made of iron, with relatively high hardness, and can be deformed by applying pressure. Several movable sheets 203b form a circular ring structure, and a fixed groove 203d structure is formed between two movable sheets 203b. The fixed groove 203d and the fixed block 202b are adapted to each other, and one side corner of several movable sheets 203b presents an arc surface, i.e., an arc surface 203c, near the inner side, and the arc surface 203c and the extrusion surface 202c match each other.

[0037] When in use, when the casing 102 and the wheel hub 201 are connected, they are aligned horizontally with each other, at this time, the connecting ring 202a will be limited in the fixed ring 203a, and the extrusion surface 202c of the fixed block 202b is in contact with the arc surface 203c of the movable piece 203b, and the casing 102 is operated to apply force to the wheel hub 201, and the extrusion surface 202c applies pressure to the arc surface 203c, thereby driving the movable piece 203b to bend upward, and continuously moving the connecting ring 202a toward the inside of the fixed ring 203a. When the surface of one side of the fixed ring 203a is flush with one side of the fixed block 202b, the generator 101 can be rotated, so that The connecting ring 202a is driven to rotate. Since the movable sheet 203b has a certain elastic force, it will exert pressure on the fixed block 202b after deformation. As the connecting ring 202a rotates, the fixed block 202b is driven to rotate. When the fixed block 202b is completely limited in the fixing groove 203d, the movable sheet 203b rebounds, and the front and rear edges of the movable sheet 203b will contact the fixed block 202b and will resist the fixed block 202b, making it impossible for the fixed block 202b to continue to rotate, which connects the fixed block 202b and the movable sheet 203b together, thereby achieving the effect of connecting the connecting ring 202a and the fixed ring 203a together.

[0038] Example 2

[0039] Reference Figures 3 to 6, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a connecting unit 200 of a fixing mechanism, which solves the problem of how to reinforce and unlock the connecting ring 202a and the fixing ring 203a after being connected, and includes an adjusting component 204, the adjusting component 204 is arranged on the movable sheet 203b, and the adjusting component 204 includes an open groove 204a arranged on the outer side of the movable sheet 203b, a triangular groove 204b arranged on the inner side of the movable sheet 203b, and a triangular groove 204a arranged on the inner side of the movable sheet 203b. 04b; the trapezoidal block 204c is movably connected in the triangular groove 204b, and a rectangular opening groove 204a is opened near the central position on the outer surface of a plurality of movable pieces 203b, and a triangular groove 204b is opened at the bottom of the opening groove 204a, and the trapezoidal block 204c is slidably connected in the triangular groove 204b, and the inner wall slope of the triangular groove 204b is located directly above the trapezoidal block 204c, and the upper side slope of the trapezoidal block 204c is parallel to and fits with the inner wall slope of the triangular groove 204b.

[0040] Among them, several trapezoidal blocks 204c are connected to a limiting ring 205b, and the limiting ring 205b and the thread groove 205a arranged on the outer side of the fixed ring 203a cooperate to realize threaded connection. This makes it possible for the limiting ring 205b to be rotated clockwise after the movable piece 203b is deformed and the fixed block 202b has been limited in the fixed groove 203d, so that the limiting ring 205b moves to one side, exerting inward pressure on the movable piece 203b, so that the movable piece 203b is reset, thereby increasing the stability of the fixed block 202b being limited in the fixed groove 203d, and preventing The fixing block 202b is stopped from separating from the fixing groove 203d, and the inner wall of the fixing ring 203a is close to one side and presents a conical inclined groove 205c, whose function is that when the extrusion surface 202c applies pressure to the arc surface 203c, the movable piece 203b has enough space to deform after bending, and the inner wall of the inclined groove 205c is provided with an extrusion groove 205d, and the inner wall of the extrusion groove 205d is connected to a plurality of trapezoidal blocks 204c, and the inner wall of the extrusion groove 205d is squeezed by the rotation of the limit ring 205b so as to drive the trapezoidal block 204c to move.

[0041] Further, it further includes a sliding component 206. The sliding component 206 is arranged on the fixed ring 203a and cooperates with the limiting ring 205b. The sliding component 206 includes a sliding groove 206a arranged on the other side of the fixed ring 203a, a slider 206b arranged in the sliding groove 206a, and a connecting block 206c arranged on the slider 206b. A sliding groove 206a is formed on the other side surface of the fixed ring 203a. The sliding groove 206a is a circular "L"-shaped groove, and its inner wall is slidably connected with the slider 206b. The slider 206b is in an "L" shape. The "L" shape of the slider 206b can cooperate with the "L"-shaped groove on the inner wall of the sliding groove 206a, so that the slider 206b can move along a specific path in the sliding groove 206a and maintain the correct direction. A connecting block 206c is fixedly connected to the other side of the sliding block. The connecting block 206c is in a "匚" shape. A telescopic groove 207a is formed on one side surface of the connecting block 206c. Two springs 207b are arranged in the telescopic groove 207a. The two springs 207b are commonly connected to a limiting block 207c. The limiting block 207c is in a "山" shape. The central part of the limiting block 207c is connected to the spring 207b, and the inner walls of its two side parts are in contact with the front and rear surfaces of the connecting block 206c. Its function is to improve the stability of the limiting block 207c during movement. The telescopic groove 207a allows the limiting block 207c to expand and contract inside the telescopic groove 207a. Combined with the spring 207b, through the stretching elastic force of the spring 207b, the limiting block 207c is always pushed to extend in one direction. The limiting block 207c commonly connected by the two springs 207b slides in the limiting groove 207d on the outer wall of the limiting ring 205b. This limiting mechanism can limit the maximum expansion and contraction range of the limiting block 207c and prevent it from exceeding a specific range. A limiting groove 207d is formed on the outer wall of the limiting ring 205b, and the limiting block 207c is adapted to the limiting groove 207d.

[0042] When in use, after the fixed block 202b is limited in the fixed groove 203d, the limiting ring 205b is rotated clockwise to reset the movable piece 203b. When the limiting ring 205b can no longer rotate, it means that the movable piece 203b is firmly fixed. At this time, the spring 207b is in a contracted state, and the squeezing force applied by the fixed ring 203a moves the connecting block 206c on the other side of the fixed ring 203a to the limiting groove 207d of the limiting ring 205b. The stretching elastic force of the spring 207b pushes the limit block 207c to move to one side, so that the limit block 207c is limited in the limit groove 207d, which makes the limit ring 205b unable to rotate, thus achieving the effect of fixing the position of the limit ring 205b at this time, and the casing 102 and the wheel hub 201 are connected. When it is necessary to separate the casing 102 and the wheel hub 201, the limit block 207c is first moved to make the limit block 207c move to the other side. The spring 207b is moved and exerts pressure on the spring 207b, causing the spring 207b to contract to the other side. As the limit block 207c slowly disengages from the limit groove 207d, the connection block 206c is free from the resistance encountered when the limit block 207c is limited in the limit groove 207d, and can be rotated along the sliding groove 206a to be away from the limit groove 207d. Without the limit block 207c, the limit ring 205b can be rotated counterclockwise. After the limit ring 205b is rotated counterclockwise, the limit ring 205b is 05b moves to the other side, and then the inner wall of the extrusion groove 205d squeezes the trapezoidal block 204c, thereby driving the trapezoidal block 204c to move to the other side, and the upper inclined surface of the trapezoidal block 204c will exert an upward oblique force on the inner inclined surface of the triangular groove 204b, and the movable piece 203b bends upward under the action of the oblique force. When the movable piece 203b bends to a certain extent, the fixed block 202b can be separated from the fixed groove 203d, thereby achieving the effect of quick unlocking.

The outer sleeve of the generator 101 is provided with a protective motor jacket 103, and its material can be made of copper shielding layer, carbon fiber composite material, thermal spray ceramic coating and other materials. Adding a motor jacket can protect against wind and rain, and can effectively prevent rainwater from penetrating into the generator 101 when it rains, thereby preventing each component from accelerating corrosion and aging, and extending the service life. At the same time, the heat generated by the generator 101 during power generation can be used to heat the protective motor jacket 103, so that the moisture on the protective motor jacket 103 evaporates quickly, ensuring the internal dryness, reasonably and effectively recycling resources, and preventing water corrosion.

[0045] Among them, the inner wall of the impeller 301 is provided with a plurality of blades 303a, the blades 303a are semi-open, which is characterized by convenient casting and easy maintenance and cleaning of impurities blocked during transportation. The impeller 301 is arranged on the right side of the casing 102, and a connecting shaft 303b is arranged at the inner center position of the impeller 301, and the connecting shaft 303b is used to connect with the generator 101. The power cabin 302 is arranged on the other side of the hub 201 and is connected by bolts. An air inlet 304a is arranged on the other side of the power cabin 302, and a compressor 304b is connected to the air inlet 304a, which functions to compress the gas. A combustion chamber 304c is arranged on one side of the compressor, and a combustion-supporting material is arranged in the combustion chamber 304c. A guide channel 304d is arranged in the hub 201, and the guide channel 304d is used to guide the high-temperature and high-pressure gas generated by the combustion chamber 304c to drive the impeller 301 to rotate.

[0046] When in use, the compressor 304b compresses the gas in the air inlet 304a, and the compressed gas enters the combustion chamber 304c, where it is fully mixed with the fuel and burned to produce high-temperature and high-pressure gas. The gas then expands the impeller 301 through the guide channel 304d to drive the generator 101 to generate electricity. The three-phase AC power generated by the generator 101 is used for the electrical equipment of the low-altitude aircraft, thereby providing reliable and continuous power support for plateau UAV aircraft.
