Description

Technical Field

[0001] The present invention relates to the technical field of logistics transport drones, and in particular to a new energy low-altitude short-distance logistics transport drone. Background Art

[0002] In recent years, new energy low-altitude short-distance logistics transport drones have played an important role in the modern logistics system, especially in improving logistics efficiency, reducing costs and reducing environmental impact. Such drones can quickly deliver goods in congested cities or hard-to-reach remote areas, avoiding the limitations of ground transportation, thereby significantly shortening delivery time. Compared with traditional ground transportation or manned aircraft, drone logistics can significantly reduce operating costs, including labor costs, fuel costs, etc., and in some cases can achieve higher economic benefits.

[0003] Some new energy low-altitude short-distance logistics transport drones in the prior art usually need to tighten or loosen multiple bolts when taking and placing goods and replacing storage boxes of different sizes to ensure the safe fixation of goods and the stable installation of storage boxes. This is to loosen or lock the goods and storage boxes. Manually tightening or loosening multiple bolts will not only increase the complexity of the operator's work, but may also significantly reduce the overall efficiency of logistics distribution when time is tight. Frequent manual operations may also increase the possibility of misoperation. For example, forgetting to tighten a bolt may cause the goods or storage boxes to loosen or even fall off during flight, thereby posing a safety hazard. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1

[0035] Reference Figure 1 to Figure 4 and Figure 6 to Figure 9 , which is the first embodiment of the present invention, provides a new energy low-altitude short-distance logistics transport drone, the device includes:

[0036] The logistics drone 100 includes a drone body 101, a fixed box 102 disposed directly below the drone body 101, and a drawer 103 in sliding contact with the inner wall of the fixed box 102;

[0037] It should be noted that the drone body 101 is the main body of the logistics drone 100 and is responsible for flight and transportation. The fixed box 102 is loaded with drawers 103 and goods, and the drawers 103 are used to store and take out goods.

[0038] The pick-and-place assembly 200 includes a load-bearing assembly 201 located on the inner wall of the fixed box 102, a limit assembly 202 and a locking assembly 203 used to lock the fixed box 102 and the drawer 103, and a plug-in assembly 204 and a positioning assembly 205 used to connect the drone body 101 and the fixed box 102.

[0039] Specifically, the bearing assembly 201 includes a fixing plate 201a fixedly connected to the inner wall of the fixing box 102, a mounting groove 201b and a straight groove 201c respectively opened on both side surfaces of the fixing plate 201a, and a first spring 201d fixedly installed on the inner surface of the fixing plate 201a.

[0040] It should be noted that the fixed plate 201a is used to support the components in the bearing assembly 201, the limiting assembly 202 and the locking assembly 203, the mounting groove 201b is used to install the movable hook 202i, the straight groove 201c is used to limit the concave slider 202a through the fixing plate 203b, and the first spring 201d is used to reset the concave slider 202a.

[0041] Furthermore, the limiting assembly 202 includes an inner concave slider 202a arranged above the fixed plate 201a, a concave stopper 202b fixedly connected to the center position of the inner wall of the inner concave slider 202a, a convex stopper 202c fixedly connected to the inner side wall of the inner concave slider 202a, a through opening 202d connected to the inner cavity of the inner concave slider 202a, a first groove 202e connected to the outside of the through opening 202d, a first inclined block 202f fixedly connected at a right angle to the first inclined block 202e, a second inclined block 202g fixedly connected at a right angle to the first inclined block 202f, and a second groove 202h fixedly connected at a right angle to the second inclined block 202g, and an active hook 202i movably connected to the inner wall of the mounting groove 201b and used in conjunction with the concave stopper 202b.

[0042] It should be further explained that the outer end surface of the hook 202i is in sliding contact with the inner wall of the concave slider 202a, and the concave slider 202a can be limited by the cooperation between the concave stopper 202b and the hook 202i.

[0043] Among them, the outer end surface of the first spring 201d is fixedly connected to the outer surface of the concave slider 202a, the first bevel 202e and the second bevel 202h are respectively located at the inclined surface and the plane of the concave stopper 202b, the first inclined block 202f and the second inclined block 202g are both located at the concave surface of the concave stopper 202b, and the limiting end of the movable hook 202i is located in the through opening 202d.

[0044] Preferably, the locking assembly 203 includes a connecting rod 203a fixedly connected to the outer surface of the concave slider 202a, a fixing plate 203b fixedly connected to the bottom of both sides of the fixing plate 201a, an inclined groove 203c opened on the surface of the fixing plate 203b, a sliding column 203d slidingly contacting the inner wall of the inclined groove 203c, a swing rod 203e fixedly sleeved on the outer surface of the sliding column 203d, an L-shaped rod 203f fixedly connected to the outer end surface of the swing rod 203e, a clamping block 203g fixedly installed on the outer surface of the drawer 103 and used in conjunction with the L-shaped rod 203f, and a supporting block 203h fixedly connected to the bottom of the fixing plate 201a and used in conjunction with the swing rod 203e.

[0045] Among them, the angle of the inclined groove 203c changes from low to high from the support block 203h to the position close to the connecting rod 203a. When the inclined groove 203c squeezes the sliding column 203d, the sliding column 203d can drive the swing rod 203e and the L-shaped rod 203f to rotate. Through the cooperation of the L-shaped rod 203f and the clamping block 203g, the drawer 103 can be locked.

[0046] It should be noted that the outer surface of the fixed plate 203b is in sliding contact with the inside of the straight groove 201c, the outer surface of the swing rod 203e is in sliding contact with the inner surface of the fixed plate 203b, and the outer end surface of the swing rod 203e is fixedly installed on the inner surface of the support block 203h through an axis.

[0047] When in use, the goods are loaded into the drawer 103, and then the drawer 103 is pushed into the fixed box 102. The drawer 103 squeezes the concave slider 202a through the connecting rod 203a, and drives the clamping block 203g to move to a position close to the L-shaped rod 203f. The movable hook 202i is limited at the plane of the second groove 202h, so that the limited end of the movable hook 202i enters the first groove 202e through the through hole 202d, and rises to the maximum along the first groove 202e, and then falls to the first inclined block 202f. The concave surface of the concave stopper 202b limits the movable hook 202i, so that the movable hook 202i rises to the maximum along the first inclined block 202f, and moves to a position in contact with the concave surface of the concave stopper 202b, thereby limiting the concave slider 202a.

[0048] At the same time: the concave slider 202a squeezes the first spring 201d, and drives the fixing piece 203b to move linearly along the inner wall of the installation groove 201b, and the fixing piece 203b squeezes the sliding column 203d through the inclined groove 203c, so that the sliding column 203d rises along the inner wall of the inclined groove 203c, and drives the swing rod 203e and the L-shaped rod 203f to rotate, so that the L-shaped rod 203f hooks the clamping block 203g, so as to achieve the effect of locking the drawer 103;

[0049] When the drawer 103 needs to be unlocked: the drawer 103 is continuously pushed toward the inside of the fixed box 102, so that the drawer 103 squeezes the concave slider 202a through the connecting rod 203a, and drives the clamping block 203g to move to a position where it is out of contact with the L-shaped rod 203f. The movable hook 202i is limited by the convex stopper 202c, so that the movable hook 202i rises to the maximum along the second inclined block 202g and falls to the second groove 202h. At this time, the concave slider 202a loses the limit of the movable hook 202i, and the movable hook 202i is released through the second groove 202h. The reaction force of a spring 201d pushes the concave slider 202a back, and the concave slider 202a squeezes the drawer 103 out of the fixed box 102 through the connecting rod 203a, and drives the fixed plate 203b to move synchronously. The fixed plate 203b squeezes the sliding column 203d through the inclined groove 203c, so that the sliding column 203d descends along the inner wall of the inclined groove 203c, and drives the swing rod 203e and the L-shaped rod 203f to rotate in the opposite direction to the initial position, ensuring that the clamping block 203g passes smoothly, so as to achieve the effect of unlocking the drawer 103.

[0050] In summary, the cooperation of the components in the load-bearing assembly 201, the limiting assembly 202 and the locking assembly 203 can not only utilize the power when inserting the drawer 103 to automatically and firmly lock the drawer 103 to prevent the goods from accidentally falling off during transportation, but also can push the drawer 103 to make the drawer 103 and the goods automatically pop out, thereby simplifying the operating process and improving the loading and unloading efficiency, so as to achieve the effect of significantly improving the convenience and efficiency of loading and unloading operations without affecting the safety of the goods.

[0051] Example 2

[0052] Reference Figure 1 , Figure 3 Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a plug-in component 204 and a positioning component 205 are capable of quickly connecting different types of fixing boxes 102 to the bottom of the drone body 101.

[0053] Furthermore, the plug-in assembly 204 includes a fixed column 204a fixedly installed on the top of the fixed box 102, a fixed rod 204b fixedly connected to the outer end surface of the fixed column 204a, a bevel extrusion block 204c fixedly connected to the other end of the fixed rod 204b, and a bevel sliding block 204d slidably mounted on the outer surface of the fixed rod 204b.

[0054] It should be explained that the inclined surface pressing block 204 c and the inclined surface sliding block 204 d have the same shape, and when the inclined surface pressing block 204 c and the inclined surface sliding block 204 d are in contact, they can temporarily form a whole.

[0055] Furthermore, the top of the inclined pressing block 204c is an inclined surface and the bottom is a flat surface, and the top of the inclined sliding block 204d is a flat surface and the bottom is an inclined surface.

[0056] Specifically, the positioning assembly 205 includes a sleeve 205a fixedly installed at the bottom of the drone body 101 and used in conjunction with the fixed column 204a, limiting grooves 205b respectively opened on the inner walls on both sides of the sleeve 205a, a second spring 205c fixedly installed on the inner wall of the limiting groove 205b, and a trapezoidal limiting block 205d fixedly connected to the other end of the second spring 205c and used in conjunction with the inclined extrusion block 204c.

[0057] It needs to be explained that when the fixed column 204a is inserted into the sleeve 205a, the fixed column 204a drives the inclined extrusion block 204c to squeeze the trapezoidal limit block 205d through the fixed rod 204b, so that the trapezoidal limit block 205d is squeezed into the limit groove 205b, and at the same time, a pressure is applied to the second spring 205c. When the bottom of the inclined extrusion block 204c moves to the top of the trapezoidal limit block 205d, the trapezoidal limit block 205d is extended through the second spring 205c and limits the trapezoidal limit block 205d.

[0058] Preferably, the outer surface of the trapezoidal limiting block 205d is in sliding contact with the inner wall of the limiting groove 205b, and the top of the limiting groove 205b is a plane and the bottom is an inclined surface.

[0059] When in use, the fixing column 204a is inserted into the sleeve 205a, and the fixing column 204a drives the inclined extrusion block 204c to squeeze the trapezoidal limiting block 205d through the fixing rod 204b, so that the trapezoidal limiting block 205d is squeezed into the limiting groove 205b, and at the same time, a pressure is applied to the second spring 205c. When the bottom of the inclined extrusion block 204c moves to the top of the trapezoidal limiting block 205d, the trapezoidal limiting block 205d extends out through the second spring 205c and limits the inclined extrusion block 204c, so that the inclined extrusion block 204c limits the fixed box 102 through the fixing rod 204b and the fixing column 204a, so as to achieve the effect of quickly connecting the fixed box 102 to the bottom of the drone body 101.

[0060] When it is necessary to replace the fixed box 102 of a different type: push the fixed column 204a into the sleeve 205a again, so that the fixed column 204a drives the inclined sliding block 204d to squeeze the trapezoidal limit block 205d into the limit groove 205b, and apply a pressure to the second spring 205c. When the bottom of the inclined sliding block 204d moves to the top of the trapezoidal limit block 205d, the trapezoidal limit block 205d extends out through the second spring 205c and clamps the inclined sliding block 204d. At this time, the sleeve 205a is pushed. The fixed column 204a is moved externally, and the fixed column 204a drives the inclined surface extrusion block 204c to move to a position in contact with the inclined surface sliding block 204d through the fixed rod 204b, and temporarily forms a whole, and then the fixed column 204a continues to be moved outside the sleeve 205a. The fixed column 204a drives the inclined surface extrusion block 204c and the inclined surface sliding block 204d through the fixed rod 204b to squeeze the trapezoidal limit block 205d into the limit groove 205b, so as to release the connection between the fixed box 102 and the drone body 101.

[0061] In summary, through the cooperation of the plug-in component 204 and the positioning component 205, the drone body 101 and the fixed box 102 can be quickly connected and disassembled, so as to improve the convenience of loading and unloading goods while adapting to various logistics needs.
