[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the invention is usually placed when in use. This is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0031] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of the embodiments of this application, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in this application based on specific circumstances.

[0033] During the UAV ground taxiing test (including low-speed, medium-speed, and high-speed taxiing), in order to meet the test requirements, the UAV needs to taxi frequently at different speeds and different braking levels, which will cause rapid wear of the tires. The main reasons are:

[0034] 1. Sliding friction wear

[0035] When a drone glides on the ground, constant friction occurs between the tires and the ground. As the gliding distance and frequency increase, the tire surface material gradually wears away. The contact pressure and friction coefficient between the tire and the ground also vary at different gliding speeds. At high speeds, tire wear can be more severe because the contact time is shortened but the impact force is increased.

[0036] 2. Impact of the brake system

[0037] Frequent braking increases friction between the tire and the road, especially during emergency or high-intensity braking, which can cause significant wear on the tire surface. Furthermore, different braking methods (such as mechanical brakes, brake-by-wire brakes, etc.) and braking efficiency also affect tire wear. An inefficient braking system may require longer braking distances and greater braking force, thus increasing tire wear.

[0038] 3. Tire materials and design

[0039] The wear resistance, tear resistance and other properties of tire materials directly affect the service life. Tires with poor wear resistance are more likely to wear during sliding.

[0040] 4. Environmental factors

[0041] Different ground conditions (such as dry, wet, sandy, etc.) will affect tire wear. High or low temperatures may also affect tire materials, resulting in reduced tire performance and increased wear.

[0042] Some drone tires may be made of specialized materials or structural designs, making installation and removal complex and requiring specialized tools and methods. This is especially true for tires on large drones, which can be heavy. Manual installation and removal is not only laborious but can also pose safety risks. Furthermore, at drone ground taxiing test sites, the necessary customized tooling, space, and equipment to support tire installation and removal may be lacking. Therefore, frequent tire replacements require specialized tools.

[0043] Based on the above situation, the present application proposes a drone tire disassembly and assembly device, which may include a lifting assembly 3, a receiving seat 2, an auxiliary support assembly 1, and at least two limiting assemblies 4. The receiving seat 2 is mounted on the output end of the lifting assembly 3, and is used to drive the receiving seat 2 to rise and fall via the lifting assembly 3. The lifting assembly 3 and the limiting assemblies 4 are both mounted on the auxiliary support assembly 1. In actual application, the connection between the lifting assembly 3 and the limiting assemblies 4 and the auxiliary support assembly 1 can be adjusted according to actual needs and can be a detachable connection or a fixed connection. If a detachable connection is adopted, the structure of the drone tire disassembly and assembly device of the present application is more flexible and can be applied to more types of drone tires. In addition, the lifting assembly 3 can adopt any existing structure that can provide lifting power. The limiting assemblies 4 can limit the lifting and falling of the tire on the receiving seat 2. The specific structure and shape of the limiting assemblies 4 are not limited. At least two limiting assemblies 4 are located above the receiving seat 2 and are evenly distributed along the circumference, so that the limiting assemblies 4 have a projected area on the surface of the receiving seat 2. Therefore, the limiting assemblies 4 can limit the position of the tire.

[0044] During use, the tire to be removed is placed on the lifting assembly 3, which is not fixedly connected to the lifting assembly 3. After the tire is placed on the pallet, the lifting assembly 3 raises the receiving seat 2. When the tire is raised to the limit assembly 4, the limit assembly 4 separates the tire and the wheel hub through the reaction force, achieving rapid removal of the tire. In practical applications, the drone tire removal and assembly device of this application can also be used as an installation platform to perform other related operations on drone tires.

[0045] like Figure 1 As shown, a specific embodiment of a tire disassembly and assembly device for a drone of the present application can include a lifting component 3, a receiving seat 2, an auxiliary support component 1 and four limit components 4.

[0046] The auxiliary support assembly 1 includes a base 11 and four columns 12. The base 11 is cross-shaped, and there are four columns 12. The four columns 12 are respectively connected to the four edges of the base 11. The receiving seat 2 is spatially located at the center of the base 11. The receiving seat 2 is disc-shaped, and the four columns 12 are respectively located on the periphery of the receiving seat 2. It should be noted that in other embodiments of the present application, the specific shape of the base 11 and the specific number of columns 12 can be adjusted according to processing requirements and are not limited by this application.

[0047] The position-limiting assembly 4 comprises a position-limiting member and a connecting member. The position-limiting member comprises a base, a first side portion, and a second side portion. The first and second side portions are connected to either side of the base, forming an overall door-shaped structure. One end of the connecting member is connected to the upright 12, and the other end is connected to one end of the base. The other end of the base extends directly above the receiving seat 2, enabling the position-limiting member to function properly. In this embodiment, the connecting member is a bolt.

[0048] In practical applications, the base 11 can adopt a channel steel structure. During processing, it can be welded together by three channel steels. The three channel steels are one long and two short. The two short channel steels are fixed on both sides of the long channel steel by welding. The specific structural parameters of the channel steel can be set according to the overall structural requirements. For example, the thickness of the channel steel is 5mm. This type of base 11 has a simple structural connection form, strong material hardness, not easy to break, and high mechanical strength.

[0049] In actual applications, the column 12 can also adopt a channel steel structure, with a total of four columns of the same length. Each column 12 is connected to the base 11 by welding, and the thickness of the channel steel used for the column 12 is 5mm. The column 12 in this embodiment has a simple connection form, strong material hardness, not easy to break, and higher mechanical strength. As a way to connect the limiter, holes are made on the top of each column 12 for connecting the column 12 and the limiter by bolts. The limiter also adopts a channel steel structure, with a total of four. The lengths of the four limiters can be consistent, and the thickness of the channel steel is 5mm. Each limiter is connected to the column 12 by bolts. The connection form is simple, easy to assemble and disassemble, the material is not easy to break, and the mechanical strength is higher.

[0050] In some embodiments of the present application, the cradle 2 can be made of steel, has a disc-shaped structure, and is 5 mm thick. It is mounted on the output end of the lifting assembly 3 and is used to secure the tire. The cradle 2 has a simple structure and high strength. The lifting assembly 3 can be a jack with a corresponding handle for easy operation. The jack's tonnage can be configured according to the required usage to ensure a certain degree of reliability.

[0051] When in use, the base 11, column 12, limit piece, receiving seat 2 and lifting assembly 3 can be installed and fixed, and then the tire to be replaced can be placed on the receiving seat 2. Then the lifting assembly 3 can be operated to lift the receiving seat 2 and the tire together. When the tire contacts the limit piece above, the reaction force of the limit piece can be relied upon to achieve the goal of separating the tire and the wheel hub.

[0052] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
