[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] A UAV landing assistance platform, such as Figure 1 and Figure 6 As shown, it includes a driving device 1, a base layer mechanism 2, a primary telescopic mechanism 3 and a secondary telescopic mechanism 4.

[0030] like Figure 2 As shown, the base layer mechanism 2 is used to support the primary telescopic mechanism 3 and the secondary telescopic mechanism 4 and to install the driving device 1. One end of the base layer mechanism 2 is connected to the primary telescopic mechanism 3, and the other end of the base layer mechanism 2 is connected to one side of the drone hangar. The base layer mechanism includes a base layer platform 21, and the driving device 1 and the primary telescopic mechanism 3 are respectively arranged at the front and rear ends of the base layer platform 21 in the length direction.

[0031] like Figure 2 and Figure 7 As shown, the driving device 1 is used to provide driving force for the extension and retraction of the first-level telescopic mechanism 3, and includes a driving motor 11 and a reducer 12. The driving motor 11 and the reducer 12 are both fixedly connected to the base layer platform 21, and the driving motor 11, the reducer 12 and the first-level telescopic mechanism are connected in sequence.

[0032] like Figure 2As shown, the primary telescopic mechanism 3 is used to drive and connect the secondary telescopic mechanism 4, which includes a primary platform 31 and a first synchronization mechanism. The primary platform 31 can move forward and backward along the base layer platform 21. The first synchronization mechanism is arranged on the base layer platform 21 in the base layer mechanism 2, and is used to transmit the driving force of the driving device 1 to the primary platform 31 so as to complete the forward and backward movement of the primary platform relative to the base layer platform 21.

[0033] like Figure 2 and Figure 3 As shown, the first synchronous mechanism includes a first synchronous belt 321, a first synchronous pulley 322 and a first synchronous assembly 323; the first synchronous pulley 322 is arranged in the base layer mechanism 2 and connected to the drive device 1, specifically connected to the reducer 12 in the drive device 1; the first synchronous assembly 323 is fixedly connected to the base layer mechanism and the first telescopic mechanism respectively to transmit the driving force of the drive device 1 to the first telescopic mechanism 3, so that the first telescopic platform can be telescoped. Figure 5 As shown, the first synchronous assembly includes a first belt pressure plate 3231 and a second synchronous belt pulley 3232, and the second synchronous belt pulley 3232 is fixedly arranged in the base layer mechanism 2. The first synchronous belt pulley 322 is wound around the first synchronous belt pulley 322 and the second synchronous belt pulley 3232, so that the first synchronous belt pulley 322 forms a ring. The first belt pressure plate 3231 is fixedly connected to the first-level platform 31 and the lower side of the first synchronous belt 321, as shown in FIG. Figure 2 As shown, the secondary telescopic mechanism 4 is arranged on the primary telescopic mechanism 3, specifically, on the primary platform 31, and the secondary telescopic mechanism 4 can move forward and backward along the primary telescopic mechanism 3. The secondary telescopic mechanism 4 includes a secondary platform 41 and a second synchronization mechanism 42, and the secondary platform 41 is moved forward and backward relative to the primary platform 31 by the second synchronization mechanism 42, thereby completing the synchronous telescopic of the secondary telescopic mechanism 4 and the primary telescopic mechanism 3.

[0034] like Figure 2 and Figure 3 As shown, the second synchronous mechanism 42 includes a second synchronous belt 421, and a second synchronous component 422 and a third synchronous component 423 provided at the front and rear ends of the first-level platform; the second synchronous belt 421 forms an annular belt through the second synchronous component 422 and the third synchronous component 423. The lower side of the second synchronous belt 421 is fixedly connected to the base layer mechanism 2 through the second synchronous component 422, and the upper side of the second synchronous belt 421 is fixedly connected to the secondary telescopic mechanism 4 through the third synchronous component 423.

[0035] Specifically, Figure 4As shown, the second synchronous assembly 422 includes a second belt pressure plate 4221 and a third synchronous pulley 4222; the third synchronous assembly 423 includes a third belt pressure plate 4231 and a fourth synchronous pulley 4232. The second synchronous belt 421 is wound around the third synchronous pulley 4222 and the fourth synchronous pulley 4232 to form a ring. The third synchronous pulley 4222 and the fourth synchronous pulley 4232 are fixedly arranged at the front and rear ends of the first-level platform 31. One end of the lower side of the second synchronous pulley 421 is fixedly connected to the base layer platform 21 through the second belt pressure plate 422, and one end of the upper side of the second synchronous pulley 421 is fixedly connected to the secondary platform 41 through the third belt pressure plate 4231.

[0036] During operation, the drive motor 11 is started, and then the first synchronous pulley 322 is decelerated through the reducer 12 to rotate counterclockwise. At this time, the upper side of the first synchronous belt 321 moves backward, and the lower side of the first synchronous belt 321 moves forward. The first synchronous pulley 322 drives the synchronous belt 321 and the second synchronous pulley 3232 to make a reverse circular rotation. Since a fixed connection is formed between the lower side of the first synchronous belt 321 and the first-level platform 31 through the first belt pressure plate 3231, as the lower side of the second synchronous belt 321 moves forward, the first-level platform 31 also moves forward, thereby completing the extension of the first-level telescopic mechanism 3.

[0037] During the forward movement of the primary platform 31, since the lower side of the second synchronous belt 421 forms a fixed connection with the base layer platform 21 through the second belt pressure plate 422, when the primary platform 31 is extended, the upper side of the second synchronous belt 421 will also move forward and drive the third synchronous belt pulley 4222 to rotate clockwise. Since one end of the upper side of the second synchronous belt 421 is fixedly connected to the secondary platform 41, when the upper side of the second synchronous belt 421 moves forward, the secondary platform 41 is also moved forward by the drive of the third belt pressure plate 4231, thereby completing the extension of the secondary telescopic mechanism 4.

[0038] Among them, the base layer platform 21, the first level platform 31 and the second level platform 41 form a landing runway for the drone to enter the hangar. When needed, the first synchronous pulley 322 is rotated counterclockwise by the driving device 1 so that the auxiliary platform can be extended from one side of the hangar, thereby forming a longer platform to assist the drone to land; after use, the first synchronous pulley 322 is rotated clockwise by the driving device 1 to complete the synchronous contraction of the first level telescopic mechanism 3 and the second level telescopic mechanism 4, and the auxiliary platform can be contracted so that the auxiliary platform can be stored in the drone hangar.

[0039] It can be seen that the technical solution only needs one driving device to complete the secondary extension and retraction of the auxiliary platform, which not only simplifies the structure of the landing auxiliary platform, but also reduces the weight. At the same time, through the above synchronization mechanism, when the primary platform moves linearly, the secondary platform also realizes linear motion at the same time, so that the auxiliary platform also saves time when expanding and retracting.

[0040] Embodiment 2:

[0041] This embodiment is different from Embodiment 1 in that Figure 2 As shown, the UAV landing auxiliary platform also includes a photoelectric sensor 15. The photoelectric sensor 15 is arranged on one side of the base layer platform 21. The photoelectric sensor 15 detects the motion state of the first synchronous belt 321, thereby realizing the control of the extension, retraction and intermediate state of the first-level platform 31 and the second-level platform 41.

[0042] At the same time, in order to make the extension and retraction of each platform more flexible, the base layer platform 21 and the first-level platform 31 are also provided with slide rails to reduce the friction between the first-level platform 31 and the base layer platform 21, and between the second-level platform 41 and the first-level platform 31.

[0043] In addition, in order to ensure the safety of the auxiliary landing platform extension process, Figure 4 and Figure 5 As shown, the first synchronous assembly 323, the second synchronous assembly 422 and the third synchronous assembly 423 are all provided with a limiting device 5, and the limiting device 5 is respectively arranged on one side of the second synchronous belt pulley, the third synchronous belt pulley and the fourth synchronous belt pulley.

[0044] It should be noted that the technical features in the above-mentioned embodiments 1 to 2 can be combined arbitrarily, and the combined technical solutions all belong to the protection scope of the present application. And in this article, terms such as "including", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.
