[0001] The present application relates to the technical field of carrying transportation equipment, in particular to a telescopic platform. BACKGROUND

[0002] With the rapid development of low-altitude economy, the use of unmanned aerial vehicles and other low-altitude flight equipment for goods transportation is gradually popularized and applied in various fields.

[0003] At present, unmanned aerial vehicles are mainly used for goods distribution between logistics sites. However, in actual application, the pain point of express delivery and logistics transportation is the "last 100 meters" of distribution, that is, the road from the logistics substation or the user's downstairs to the user's hand; however, since the unmanned aerial vehicle cannot approach the building facade for delivery during transportation, and the building facade also does not have a matching receiving platform for the unmanned aerial vehicle, the unmanned aerial vehicle cannot solve the problem of "the last 100 meters" of goods transportation. SUMMARY

[0004] Therefore, the present application provides a telescopic platform which can be used in conjunction with an unmanned aerial vehicle to deliver goods through a building window or to a building indoor, solve the problem of "the last 100 meters" of goods transportation, improve the efficiency of goods transportation, and promote the development of low-altitude economy.

[0006] The telescopic structure includes a telescopic bracket, two telescopic side frames, and a blocking frame; at least part of the telescopic bracket is located outside the building window;

[0007] The two telescopic side frames are arranged on opposite sides of the telescopic bracket and are connected with the telescopic bracket; the two telescopic side frames and the telescopic bracket can be synchronously telescoped in a first direction; the first direction is perpendicular to the plane in which the building window is located;

[0008] The blocking frame is located on the side of the telescopic bracket away from the building window and is connected with the telescopic bracket and the two telescopic side frames;

[0009] The driving mechanism is installed on the wall in which the building window is located; the driving mechanism is connected with the telescopic structure, and the driving mechanism is used to drive the telescopic bracket and the two telescopic side frames to be synchronously telescoped in the first direction.

[0010] In one of the embodiments, the telescopic side frame includes a plurality of support rods, and the plurality of support rods are sequentially and circularly connected; adjacent support rods are distributed in a V-shaped cross.

[0011] In one of the embodiments, the telescopic bracket includes a plurality of support rods, and the plurality of support rods are arranged in intervals along the first direction;

[0012] A plurality of said supporting rods are located between two said telescopic side frames; two ends of each said supporting rod are connected with corresponding said supporting rods respectively.

[0013] In one of the embodiments, an outer sleeve is sleeved on each said supporting rod, and the sleeve can rotate around the supporting rod.

[0014] In one of the embodiments, the driving mechanism comprises a telescopic arm and a driving member.

[0015] The telescopic arm is connected with the telescopic side frame.

[0016] The driving member is installed on the wall where the building window is located, and the driving member is connected with the telescopic arm; the driving member is used to drive the telescopic arm to telescope in the first direction, so as to drive two telescopic side frames and the telescopic bracket to telescope in the first direction synchronously.

[0017] In one of the embodiments, the driving mechanism comprises two telescopic arms; two telescopic arms are connected with two telescopic side frames one by one.

[0018] The driving member is connected with two telescopic arms, and the driving member is used to drive two telescopic arms to telescope in the first direction synchronously.

[0019] In one of the embodiments, the driving member comprises two driving parts, and two driving parts are connected with two telescopic arms one by one; the driving part is used to drive the corresponding telescopic arm to telescope in the first direction.

[0020] In one of the embodiments, the telescopic arm is provided with a connecting member on the side close to the blocking bracket, and the connecting member is connected with the blocking bracket.

[0021] In one of the embodiments, a sling mechanism is further included, and the sling mechanism is located on one side of the telescopic structure; the sling mechanism comprises two slings, and two slings are connected with two telescopic side frames correspondingly; one end of each said sling is connected with the wall where the building window is located, and the other end of each said sling is connected with the corresponding telescopic side frame.

[0023] The aforementioned telescopic platform can be installed outside a building window. When it needs to receive items transported by a drone, the drive mechanism drives the telescopic bracket and two telescopic side frames to extend synchronously along a first direction, allowing the telescopic bracket and two telescopic side frames to unfold. The telescopic bracket supports the items delivered by the drone, while the two telescopic side frames and the barrier act as a fence to prevent items from slipping out. When it is necessary to deliver items through the building window into the building, the drive mechanism drives the telescopic bracket and two telescopic side frames to retract synchronously along the first direction, causing the barrier to move synchronously. The barrier pushes the items toward the building window, delivering the items into the building. When it is necessary for the drone to deliver items from inside the building, the items are placed on the telescopic bracket, and the drive mechanism drives the telescopic bracket and two telescopic side frames to extend synchronously along the first direction. The telescopic bracket moves the items away from the building window, allowing the drone to deliver the items. In other words, the telescopic platform of this application is installed on the exterior of a building window and can be used in conjunction with drones to deliver goods through building windows or into building interiors, solving the "last 100 meters" problem of goods transportation, simplifying the transportation process, improving the efficiency of goods transportation, reducing the risk of goods loss, reducing the proportion of manual transportation, and promoting the development of the low-altitude economy.

Detailed Implementation

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] Figure 1 A schematic diagram of the structure of a telescopic platform provided in an embodiment of this application is shown; Figure 2 This illustration shows a schematic diagram of the telescopic platform in its deployed state according to an embodiment of this application. Figure 3 A schematic diagram of the structure of a telescopic platform provided in an embodiment of this application in a retracted state is shown.

[0036] See Figures 1 to 3 As shown, this application embodiment provides a telescopic platform 10 for installation on the outside of a building window 40, including a telescopic structure 11 and a drive mechanism 12. The telescopic structure 11 includes a telescopic bracket 111, two telescopic side frames 112, and a stop 113. At least a portion of the telescopic bracket 111 is located outside the building window 40. The two telescopic side frames 112 are disposed on opposite sides of the telescopic bracket 111 and connected to the telescopic bracket 111. The two telescopic side frames 112 and the telescopic bracket 111 can synchronously telescopically extend and retract along a first direction X. The first direction X is perpendicular to the plane where the building window 40 is located. The stop 113 is located on the side of the telescopic bracket 111 away from the building window 40 and is connected to the telescopic bracket 111 and the two telescopic side frames 112. The drive mechanism 12 is installed on the wall where the building window 40 is located. The drive mechanism 12 is connected to the telescopic structure 11 and is used to drive the telescopic bracket 111 and the two telescopic side frames 112 to synchronously extend and retract along the first direction X.

[0037] Specifically, in the appendix Figure 2 and Figure 3From the perspective shown, the telescopic bracket 111 is horizontally positioned outside the building window 40. One end of the telescopic bracket 111 extends into the building interior through the building window 40, allowing the item 30 to be directly delivered into the building interior and into the user's hands. Two telescopic side frames 12 can be located outside the building window 40. The two telescopic side frames 112 are positioned on opposite sides of the telescopic bracket 111, approximately perpendicular to the telescopic bracket 111. Both telescopic side frames 112 are connected to the telescopic bracket 111. The two telescopic side frames 112 and the telescopic bracket 111 together define a transport channel, the space of which can change with the telescopic movement of the telescopic side frames 112 and the telescopic bracket 111. A baffle 113 is located on the side of the telescopic bracket 111 away from the building window 40, and the baffle 113 is connected to the telescopic bracket 111 and the two telescopic side frames 112, so that the baffle 113 moves synchronously with the telescopic bracket 111 and the two telescopic side frames 112. The telescopic bracket 113 and the two telescopic side frames 112 can act as a fence to prevent the item 30 from slipping. In addition, when the item 30 needs to be delivered into the building, the drive mechanism 12 drives the telescopic bracket 111 and the two telescopic side frames 112 to retract synchronously along the first direction X, which drives the baffle 113 to move synchronously. The baffle 113 pushes the item 30 toward the building window 40 and delivers the item 30 into the building through the building window 40. When the item 30 needs to be delivered out, the item 30 is placed on the telescopic bracket 111, and the drive mechanism 12 drives the telescopic bracket 111 and the two telescopic side frames 112 to extend synchronously along the first direction X, which moves the item 30 away from the building window 40 so that the drone 20 can deliver the item 30 out.

[0038] The telescopic platform 10 provided in this embodiment can be installed outside the building window 40. When it is necessary to receive the item 30 transported by the drone 20, the drive mechanism 12 drives the telescopic bracket 111 and the two telescopic side frames 112 to extend synchronously along the first direction X, so that the telescopic bracket 111 and the two telescopic side frames 112 unfold. The telescopic bracket 111 supports the item 30 delivered by the drone 20. At this time, the two telescopic side frames 112 and the guardrail 113 can act as a barrier to prevent the item 30 from slipping out. When it is necessary to send the item 30 into the room through the building window 40, the drive mechanism 12... The telescopic bracket 111 and the two telescopic side frames 112 retract synchronously along the first direction X, causing the baffle 113 to move synchronously. The baffle 113 pushes the item 30 toward the building window 40, delivering the item 30 through the building window 40 into the building interior. When the drone 20 needs to deliver the item 30 from inside the building, the item 30 is placed on the telescopic bracket 111, causing the drive mechanism 12 to drive the telescopic bracket 111 and the two telescopic side frames 112 to extend synchronously along the first direction X. The telescopic bracket 111 moves the item 30 away from the building window 40, and the drone 20 delivers the item 30 out. In other words, the telescopic platform 10 of this application is installed outside the building window 40 and can be used in conjunction with the drone 20 to deliver the item 30 through the building window 40 or into the building interior, solving the "last 100 meters" problem of transporting the item 30, simplifying the transportation process, improving the efficiency of transporting the item 30, reducing the risk of losing the item 30, reducing the proportion of manual transportation, and promoting the development of the low-altitude economy. In addition, when it is not necessary to transport items 30, the telescopic bracket 111 and telescopic side frame 112 are in a retracted state, and the entire telescopic platform 10 is in a retracted state. The entire telescopic platform 10 is compact and beautiful, and does not affect the building's appearance. Furthermore, the telescopic platform 10 can be used as an outdoor clothes rack; when the telescopic platform 10 is located above the air conditioner outdoor unit, it can serve as an air conditioner outdoor unit cover.

[0039] It should be noted that the item 30 mentioned in this application may be a courier parcel, commonly used building materials for decoration (prefabricated wall panels, long moldings, construction waste, tiles, furniture, etc.).

[0040] In one embodiment, see [reference] Figure 1 As shown, the telescopic side frame 112 includes multiple support rods 1121, which are connected end to end in sequence; adjacent support rods 1121 are distributed in a V-shape.

[0041] Specifically, in the appendix Figure 1From the perspective shown, multiple support rods 1121 are hinged end to end in sequence, with adjacent support rods 1121 arranged in a V-shape, equivalent to a deformable triangle. Utilizing the inherent stability of the triangular structure, the stability of the telescopic side frame 112 can be improved. The intersecting support rods 1121 support and constrain each other, greatly enhancing the overall structure's resistance to lateral bending, torsion, and swaying. In addition, the V-shaped intersecting design allows the support rods 1121 to be almost completely folded together when retracted, thus minimizing the volume of the telescopic platform 10 in the retracted state, making the entire telescopic platform 10 compact and aesthetically pleasing.

[0042] In one embodiment, see [reference] Figure 1 As shown, the telescopic bracket 111 includes multiple support rods 1111, which are arranged at intervals along the first direction X; the multiple support rods 1111 are located between two telescopic side frames 112; and the two ends of each support rod 1111 are respectively connected to the corresponding support rod 1121.

[0043] Therefore, multiple support rods 1111 are arranged at intervals along the first direction X, which together define the bearing surface of the item 30 so that the item 30 can be supported. When the two telescopic side frames 112 telescopically extend and retract, they can drive the multiple support rods 1111 to move synchronously, so that the telescopic side frames 112 and telescopic brackets 111 telescopically extend and retract along the first direction X, so as to realize the telescopic movement of the entire telescopic platform 10, so as to move the item 30 toward or away from the building window 40, and deliver the item 30 out of the building window 40 or into the building interior. The multiple support rods 1111 are located between the two telescopic side frames 112, and the two ends of each support rod 1111 are connected to the corresponding support rod 1121. The multiple support rods 1111 can distribute the load on the two telescopic side frames 112, avoid stress concentration, and significantly improve the bearing capacity and deformation resistance of the entire telescopic structure 11.

[0044] In one embodiment, see [reference] Figure 1 As shown, each support rod 1111 is fitted with a sleeve 1112, which can rotate around the support rod 1111.

[0045] This allows for rolling friction between the item 30 and the support rod 1111, reducing the resistance when the baffle 113 pushes the item 30 toward the building window 40, so that the item 30 can be delivered into the building through the building window 40.

[0046] In one embodiment, see [reference] Figures 1 to 3As shown, the drive mechanism 12 includes a telescopic arm 121 and a drive member 122; the telescopic arm 121 is connected to the telescopic side frame 112; the drive member 122 is installed on the wall where the building window 40 is located, and the drive member 122 is connected to the telescopic arm 121; the drive member 122 is used to drive the telescopic arm 121 to extend and retract along the first direction X, so as to drive the two telescopic side frames 112 and the telescopic bracket 111 to extend and retract synchronously along the first direction X.

[0047] In the appendix Figure 1 From the perspective shown, along the first direction X, the telescopic side frame 112 includes multiple support rods 1121. The telescopic arm 121 can be connected to all odd-numbered support rods 1121 or all even-numbered support rods 1121. In this way, when the telescopic arm 121 performs telescopic movement, it can drive a group of support rods 1121 (such as all odd-numbered support rods 1121) to move. Since two adjacent support rods 1121 are hinged at the intersection point, the driven odd-numbered support rods 1121 drive the even-numbered support rods 1121 that are hinged to it to move, so that all support rods 1121 and hinge points are "connected" into a kinematic chain. The movement of any node will inevitably be transmitted to the entire structure, ensuring absolutely synchronous telescopic movement and avoiding twisting or jamming.

[0048] In one embodiment, see [reference] Figure 1 As shown, the drive mechanism 12 includes two telescopic arms 121; the two telescopic arms 121 are connected to two telescopic side frames 112 in a one-to-one correspondence; the drive member 122 is connected to the two telescopic arms 121, and the drive member 122 is used to drive the two telescopic arms 121 to extend and retract synchronously along the first direction X.

[0049] In the appendix Figure 1 From the stated perspective, the two telescopic arms 121 are positioned one-to-one on the outer side of the telescopic side frame 112, meaning that the two telescopic arms 121 are located outside the transport channel jointly defined by the telescopic bracket 111 and the two telescopic side frames 112, thus preventing interference between the telescopic arms 121 and the item 30. By connecting the two telescopic arms 121 to the two telescopic side frames 112 in a one-to-one correspondence, the drive unit 122 drives the two telescopic arms 121 to extend and retract synchronously along the first direction X, thereby enabling the two telescopic side frames 112 to extend and retract synchronously along the first direction X, ensuring the stability and smoothness of the entire telescopic platform 10's telescopic movement.

[0050] It is understandable that the telescopic boom 121 can be a multi-segment hydraulic telescopic boom 121, and the drive component 122 can be a hydraulic drive component 122.

[0051] In one embodiment, see [reference] Figure 1 As shown, the drive unit 122 includes two drive parts 122a, which are connected to two telescopic arms 121 in a one-to-one correspondence; the drive parts 122a are used to drive the corresponding telescopic arms 121 to extend and retract along the first direction X.

[0052] Therefore, by providing two drive units 122a, each of which drives its corresponding telescopic arm 121 to extend and retract along the first direction X, even if one drive unit 122a fails, the other side can still control the telescopic arm 121 to extend and retract, thus driving the telescopic structure 11 to extend and retract along the first direction X. Furthermore, the drive units 122a can be independently disassembled and replaced without removing the drive component 122.

[0053] In one embodiment, see [reference] Figure 1 and 3 As shown, the telescopic arm 121 has a connector 123 on the side near the stop 113, and the connector 123 is connected to the stop 113.

[0054] In the appendix Figure 3 From the aforementioned perspective, the connector 123 can be a connecting block. The connecting block can be located on the side of the telescopic arm 121 near the stop 113. The connecting block is connected to the stop 113, so that the telescopic arm 121 is connected to the stop 113 through the connecting block, so that the telescopic arm 121 can drive the telescopic structure 11 to perform telescopic movement along the first direction X.

[0055] In one embodiment, see [reference] Figures 1 to 3 As shown, the telescopic platform 10 also includes a sling mechanism 13, which is located on one side of the telescopic structure 11. The sling mechanism 13 includes two slings 131, which correspond to two telescopic side frames 112. One end of each sling 131 is connected to the wall where the building window 40 is located, and the other end of each sling 131 is connected to the corresponding telescopic side frame 112.

[0056] In the appendix Figure 3 From the perspective shown, the sling mechanism 13 is located above the telescopic structure 11. The two slings 131 correspond to the two telescopic side frames 112. One end of each sling 131 is connected to the wall where the building window 40 is located, and the other end of each sling 131 is connected to the corresponding telescopic side frame 112. When the telescopic bracket 111 and the two telescopic side frames 112 are extended along the first direction X, that is, when the telescopic structure 11 is in the extended state, the two slings 131 are inclined. The two slings 131 provide an upward pulling force to the telescopic structure 11, preventing the telescopic structure 11 from tilting downward under the action of gravity, so that the entire telescopic structure 11 remains horizontal.

[0057] In one embodiment, the sling mechanism 13 further includes a sling adjustment assembly 132, which is installed on the wall where the building window 40 is located. The sling adjustment assembly 132 is connected to two slings 131 and is used to release or retract the two slings 131.

[0058] Therefore, when the telescopic structure 11 extends along the first direction X, the sling adjustment mechanism 132 can release the two slings 131, so that the two slings 131 extend synchronously; when the telescopic structure 11 retracts along the first direction X, the sling adjustment mechanism 132 can retract the two slings 131, so that the two slings 131 shorten synchronously.

[0059] It should be noted that the sling adjustment assembly 132 includes a housing and a drum, a drive shaft, a transmission assembly, and a drive source disposed within the housing. For example, two drums are arranged side by side on the drive shaft, the drive source is connected to the drive shaft through the transmission assembly, and one end of each of the two slings 131 is connected to the corresponding drum. Of course, the sling adjustment assembly 132 can also have other structures, and this application does not impose any special restrictions on them.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
