Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) pod technology, and in particular to a landing pad drive device for UAV pods. Background Technology

[0002] Drone nests are widely used in various scenarios that require automated docking and launch of drones, such as drone logistics, agricultural plant protection, and power line inspection.

[0003] Currently, patent publication number CN108438245B discloses a drawer-type drone nest. In use, when a drone needs to dock, the door opens, and a drive mechanism causes the landing pad to slide out of the cavity, allowing the drone to land smoothly on it. Then, the drive mechanism controls the landing pad and drone to retract into the cavity, and the door closes the opening again. Similarly, when a drone needs to be launched, the door opens, and the drive mechanism controls the landing pad and drone to slide out of the cavity. After takeoff, the landing pad retracts into the cavity, and the door closes the cavity again. However, the drive mechanism of this drone nest can only drive the landing pad for a single-stage extension and retraction, and cannot drive it for a secondary-stage extension and retraction. Utility Model Content

[0004] One of the objectives of this utility model is to provide a landing pad drive device for unmanned aerial vehicle (UAV) pods, which aims to solve the technical problem that the existing drive mechanism of UAV pods can only drive the landing pad to perform a first-level extension and retraction, but cannot drive the landing pad to perform a second-level extension and retraction.

[0005] To achieve the above objectives, this utility model provides a landing pad drive device for an unmanned aerial vehicle (UAV) pod, including a base, a landing pad, and a drive mechanism. The drive mechanism includes a primary linear slide rail, a secondary linear slide rail, a chain transmission mechanism, and a drive source. The primary linear slide rail is fixed to the base, and the secondary linear slide rail is slidably mounted on the primary linear slide rail along its axial direction. The landing pad is slidably mounted on the secondary linear slide rail along its axial direction. A first limiting part and a second limiting part are respectively provided at both ends of the secondary linear slide rail. The drive source is fixed to the base. The chain drive mechanism is mounted on the base. The drive source is connected to the chain drive mechanism. The drive source drives the chain drive mechanism to move the landing pad along the secondary linear slide rail. When the landing pad extends along the secondary linear slide rail to abut against the first limiting part, the landing pad is driven by the drive force of the drive source to cause the secondary linear slide rail to extend along the primary linear slide rail. When the landing pad retracts along the secondary linear slide rail to abut against the second limiting part, the landing pad is driven by the drive force of the drive source to cause the secondary linear slide rail to retract along the primary linear slide rail.

[0006] Furthermore, the chain transmission mechanism includes a drive shaft, a drive sprocket, a window-opening anti-bend chain, and a chain guide assembly. The axial direction of the primary linear slide rail is a first horizontal direction, and the horizontal direction perpendicular to the first horizontal direction is designated as a second horizontal direction. The drive shaft is rotatably mounted on the base and extends along the second horizontal direction. The drive sprocket is fixed to the drive shaft, and a drive source is connected to the drive shaft to drive its rotation. The chain guide assembly is located on one side of the primary linear slide rail in the second horizontal direction, and the window-opening anti-bend chain is connected to the drive sprocket. The chain guide assembly has a first chain guide groove that passes through one end of itself near the drive sprocket. The first end of the window-opening anti-bend chain is fixedly connected to the bottom of the helipad, and the second end of the window-opening anti-bend chain is a free end. The chain core of the free end is slidably clamped by the first chain guide groove, allowing the free end of the window-opening anti-bend chain to slide along the first chain guide groove.

[0007] Furthermore, each end of the drive shaft is provided with a drive sprocket, and each drive sprocket is connected to a window-pushing anti-bending chain. The two window-pushing anti-bending chains are located on opposite sides of the first-stage linear slide rail in the second horizontal direction. There are two sets of chain guide components, which are located on opposite sides of the first-stage linear slide rail in the second horizontal direction. The chain core at the free end of each window-pushing anti-bending chain is slidably clamped by the first guide groove of the chain on each chain guide component.

[0008] Furthermore, the chain guide assembly includes a first chain guide plate and a second chain guide plate, both of which are disposed on the base. Both the first chain guide plate and the second chain guide plate extend along a first horizontal direction and are vertically spaced apart. The gap between the first chain guide plate and the second chain guide plate forms a first chain guide groove.

[0009] Furthermore, the chain guide assembly is also provided with a second chain guide groove, which extends along a first horizontal direction and is located above the first chain guide groove. The end of the second chain guide groove facing away from the drive sprocket is connected to the first chain guide groove, and the part where the end of the second chain guide groove facing away from the drive sprocket is connected to the first chain guide groove is connected by a rounded transition.

[0010] Furthermore, the chain guide assembly also includes a third chain guide plate, which is disposed on the base and extends along a first horizontal direction. The third chain guide plate and the second chain guide plate are vertically spaced apart, and the distance between the third chain guide plate and the second chain guide plate forms a second chain guide groove.

[0011] Furthermore, the third guide plate of the chain is integrally connected with the first guide plate of the chain.

[0012] Furthermore, passive sprockets are rotatably mounted on the opposite side walls of the secondary linear slide rail along the first horizontal direction. The rotation axis of the passive sprockets is parallel to the rotation axis of the transmission shaft, and the first end of each window anti-bending chain is also connected to each passive sprocket.

[0013] Furthermore, a guide wheel is horizontally rotatably mounted on the base. The rotation axis of the guide wheel is perpendicular to the axis of the primary linear slide rail, and the guide wheel can roll into contact with the bottom of the secondary linear slide rail.

[0014] Furthermore, a groove is provided on the upper surface of the secondary linear slide rail, the groove extends along the axial direction of the secondary linear slide rail, and a smooth rod extending along the axial direction of the groove is provided on the opposite side walls of the groove. A pulley is vertically provided at the bottom of the parking apron, and a groove is provided on the circumferential surface of the pulley for rolling contact with the smooth rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When the helipad driving device of this utility model is applied to a drone nest, the base is fixed inside the cavity of the nest. If the drone needs to return and dock on the helipad, the driving source of the driving mechanism drives the chain transmission mechanism to drive the helipad to slide out of the cavity of the nest along the secondary linear slide rail. When the helipad slides out along the secondary linear slide rail to abut against the first limiting part on the secondary linear slide rail, the helipad is driven by the driving force of the driving source to drive the secondary linear slide rail to slide out along the primary linear slide rail. If the drone docked on the helipad needs to enter the cavity of the nest, the driving source of the driving mechanism drives the chain transmission mechanism to drive the helipad to slide back into the cavity of the nest along the secondary linear slide rail. When the helipad slides back along the secondary linear slide rail to abut against the second limiting part, the helipad is driven by the driving force of the driving source to drive the secondary linear slide rail to slide back along the primary linear slide rail, thereby enabling the driving force of the driving mechanism to realize the secondary extension and retraction of the helipad. In summary, the drive mechanism of this utility model can not only realize the first-level extension and retraction of the helipad, but also the second-level extension and retraction of the helipad.

[0017] 2. The drive mechanism of this utility model can realize the primary and secondary extension and retraction of the helipad using the same drive source, avoiding the need to use multiple drive sources to drive the helipad to perform primary and secondary extension and retraction.

Detailed Implementation

[0027] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0028] In the description of this utility model, it should be understood that the terms "width", "upper", "lower", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Reference Figure 1 - Figure 7 This utility model provides a landing pad drive device for an unmanned aerial vehicle (UAV) pod, including a base 1, a landing pad 2, and a drive mechanism. The drive mechanism includes a primary linear slide rail 3, a secondary linear slide rail 30, a chain transmission mechanism 4, and a drive source 7. The primary linear slide rail 3 is fixed to the base 1, with its axial direction set as a first horizontal direction and its horizontal direction perpendicular to the first horizontal direction set as a second horizontal direction. The secondary linear slide rail 30 is slidably mounted on the primary linear slide rail 3 along the first horizontal direction, and the landing pad 2 is slidably mounted on the secondary linear slide rail 30 along the first horizontal direction. The two ends of the secondary linear slide rail 30 are respectively provided with a first limiting part 301 and a second limiting part 302. The drive source 7 is fixed to the base 1, and the chain transmission mechanism 4 is drivenly mounted on the base 1. The drive source 7 is drivenly connected to the chain transmission mechanism 4, and the drive source 7 is used to drive the chain transmission mechanism 4 to move the landing pad 2 along the secondary linear slide rail 30. During the sliding process of the helipad 2, when the helipad 2 slides out along the secondary linear slide rail 30 to abut against the first limiting part 301, the helipad 2 is driven by the driving force of the driving source 7 to cause the secondary linear slide rail 30 to slide out along the primary linear slide rail 3. When the helipad 2 slides back along the secondary linear slide rail 30 to abut against the second limiting part 302, the helipad 2 is driven by the driving force of the driving source 7 to cause the secondary linear slide rail 30 to slide back along the primary linear slide rail 3.

[0032] When the helipad driving device of this utility model is applied to a drone nest, the base 1 is fixed inside the cavity 9 of the nest. If the drone needs to return and dock on the helipad 2, the drive source 7 of the drive mechanism drives the chain transmission mechanism 4 to drive the helipad 2 to slide out of the cavity 9 of the nest along the secondary linear slide rail 30. When the helipad 2 slides out along the secondary linear slide rail 30 and abuts against the first limiting part 301 on the secondary linear slide rail 30, the helipad 2 is driven by the driving force of the drive source 7 to drive the secondary linear slide rail 30 along the primary linear slide rail 9. The linear guide rail 3 extends and slides out. If a drone docked on the landing pad 2 needs to enter the cavity 9 of the nest, the drive source 7 of the drive mechanism drives the chain transmission mechanism 4 to move the landing pad 2 along the secondary linear guide rail 30 and retract it into the cavity 9 of the nest. When the landing pad 2 retracts along the secondary linear guide rail 30 to abut against the second limiting part 302, the landing pad 2, under the driving force of the drive source 7, drives the secondary linear guide rail 30 to slide back along the primary linear guide rail 3, thereby enabling the driving force of the drive mechanism to realize the secondary extension and retraction of the landing pad 2. In summary, the drive mechanism of this utility model can not only realize the primary extension and retraction of the landing pad 2, but also realize the secondary extension and retraction of the landing pad 2.

[0033] In addition, the drive mechanism of this utility model can realize the first and second stage extension and retraction of the helipad 2 using the same drive source 7, avoiding the need to use multiple drive sources 7 to drive the helipad 2 to perform the first and second stage extension and retraction.

[0034] It should be noted that the two-stage telescopic design of the helipad 2 allows it to quickly expand to an appropriate size according to the take-off and landing requirements of the drone, providing sufficient take-off and landing area. This flexibility helps to cope with take-off and landing missions of different sizes and types of drones. Furthermore, this invention achieves the two-stage telescopic design of the helipad 2 using only one drive source 7 of the drive mechanism, meaning that only one driving force is needed to achieve the two-stage telescopic design of the helipad 2. In addition, compared with the drawer-type drone nest disclosed in the existing patent publication number CN108438245B, with the same extension stroke of the helipad 2 beyond the cavity 9, the two-stage telescopic design of the helipad 2 can improve the space utilization rate within the cavity 9, which is beneficial for reducing the overall volume of the drone nest.

[0035] In this embodiment, refer to Figure 1 , Figure 4 and Figure 5The chain drive mechanism 4 includes a drive shaft 40, a drive sprocket 41, a window-opening anti-bend chain 42, and a chain guide assembly 43. The drive shaft 40 is rotatably mounted on the base 1 via bearings. The drive shaft 40 extends along a second horizontal direction and is located above and behind the primary linear slide rail 3. The drive sprocket 41 is fixed to the drive shaft 40, and the window-opening anti-bend chain 42 is connected to the drive sprocket 41. The drive source 7 is a drive motor, and the output shaft of the drive motor is connected to the drive shaft 40 to drive the drive shaft 40 to rotate and drive the window-opening anti-bend chain 42.

[0036] Reference Figure 5 The chain guide assembly 43 is located on one side of the primary linear slide rail 3 in the second horizontal direction. The chain guide assembly 43 has a first chain guide groove 5 that passes through one end near the drive sprocket 41. The first end of the window-opening anti-bend chain 42 is fixedly connected to the bottom of the helipad 2, and the second end of the window-opening anti-bend chain 42 is a free end. The chain core of the free end is slidably held by the first chain guide groove 5, allowing the free end of the window-opening anti-bend chain 42 to slide along the first chain guide groove 5. Therefore, when the drive source 7 drives the transmission shaft 40 to rotate, it drives the window-opening anti-bend chain 42, thereby causing the helipad 2 to slide in the first horizontal direction. The free end of the window-opening anti-bend chain 42 slides along the first chain guide groove 5 and will not detach from the first chain guide groove 5. In addition, the chain guide assembly 43 is also provided with a second chain guide groove 6, which extends along the first horizontal direction and is located above the first chain guide groove 5. The end of the second chain guide groove 6 facing away from the drive sprocket 41 is connected to the first chain guide groove 5, and the part where the end of the second chain guide groove 6 facing away from the drive sprocket 41 is connected to the first chain guide groove 5 is connected by a rounded transition. Specifically, it can be understood that when the drive motor rotates forward, it drives the window-pushing anti-bending chain 42 to drive the helipad 2 to slide from the second limiting part 302 to the first limiting part 301. During this process, the free end of the window-pushing anti-bending chain 42 slides along the second guide groove 6 of the chain. When the helipad 2 contacts the first limiting part 301, the helipad 2 continues to be driven by the drive source 7 to drive the secondary linear slide rail 30 to slide along the primary linear slide rail 3. During this process, the free end of the window-pushing anti-bending chain 42 slides from the second guide groove 6 of the chain to the first guide groove 5 of the chain, but never disengages from the first guide groove 5 of the chain.

[0037] Similarly, when the drive motor reverses, it drives the window anti-bending chain 42 to drive the helipad 2 to slide from the first limiting part 301 to the second limiting part 302. During this process, the free end of the window anti-bending chain 42 slides along the first guide groove 5 of the chain. When the helipad 2 contacts the second limiting part 302, the helipad 2 continues to be driven by the drive source 7 to drive the secondary linear slide rail 30 to slide back along the primary linear slide rail 3. During this process, the free end of the window anti-bending chain 42 slides from the first guide groove 5 of the chain to the second guide groove 6 of the chain.

[0038] In summary, by setting the second guide groove 6 of the chain, the length of the first guide groove 5 of the chain in the first horizontal direction can be reduced, thereby reducing the overall size of the drone nest.

[0039] It should be noted that the chain transmission mechanism 4 described above can realize the multi-stage extension and retraction of the helipad 2. If the helipad 2 needs to be extended and retracted in three stages, a third-stage linear slide rail can be set on the second-stage linear slide rail 30 along the first horizontal direction, and the helipad 2 can be slidably set on the third-stage linear slide rail along the first horizontal direction. Correspondingly, a third-stage guide groove of the chain is set above the second guide groove 6 of the chain. The principle of realizing the three-stage extension and retraction of the helipad 2 is the same as the principle of realizing the two-stage extension and retraction of the helipad 2, and will not be elaborated here.

[0040] Reference Figure 5 The chain guide assembly 43 includes a first chain guide plate 430, a second chain guide plate 431, and a third chain guide plate 432. The first chain guide plate 430 and the second chain guide plate 431 are both disposed on the base 1. The first chain guide plate 430 and the second chain guide plate 431 can be detachably connected to the base 1 by screws. The first chain guide plate 430 and the second chain guide plate 431 extend along a first horizontal direction and are vertically spaced apart. The distance between the first chain guide plate 430 and the second chain guide plate 431 forms the aforementioned first chain guide groove 5.

[0041] Similarly, the third guide plate 432 of the chain is mounted on the base 1, and can be detachably connected to the base 1 by screws. The third guide plate 432 extends in a horizontal first direction, and is vertically spaced from the second guide plate 431. The distance between the third guide plate 432 and the second guide plate 431 forms the aforementioned second guide groove 6. In summary, the third guide plate 432 is integrally connected to the first guide plate 430, and the second guide plate 431 is located between the third guide plate 432 and the first guide plate 430. Thus, by adjusting the height of the first guide plate 430 or the second guide plate 431, the dimensions of the first guide groove 5 and the second guide groove 6 can be adjusted to accommodate different sizes of push-window anti-bending chains 42.

[0042] In this embodiment, refer to Figure 1 , Figure 2 and Figure 5 Both ends of the drive shaft 40 are equipped with drive sprockets 41, and each drive sprocket 41 is connected to the aforementioned window-opening anti-bending chain 42. The two window-opening anti-bending chains 42 are located on opposite sides of the first-stage linear slide rail 3 in the second horizontal direction. There are two sets of chain guide assemblies 43, which are located on opposite sides of the first-stage linear slide rail 3 in the second horizontal direction. The chain core at the free end of each window-opening anti-bending chain 42 is slidably clamped by the first chain guide groove 5 on each chain guide assembly 43. Thus, with two drive sprockets 41, two window-opening anti-bending chains 42, and two sets of chain guide assemblies 43, the process of the chain drive mechanism 4 driving the helipad 2 to extend and retract in the first horizontal direction is smoother and more stable.

[0043] In this embodiment, refer to Figure 1 or Figure 3 The secondary linear slide rail 30 is rotatably equipped with passive sprockets 303 on both sides of the opposite side wall along the first horizontal direction. The rotation axis of the passive sprockets 303 is parallel to the rotation axis of the transmission shaft 40. The first end of each window anti-bending chain 42 is also connected to each passive sprocket 303 to improve the transmission performance of the window anti-bending chain 42.

[0044] In this embodiment, refer to Figure 4 A guide wheel 8 is also horizontally rotatably mounted on the base 1. The guide wheel 8 is located in front of the primary linear slide rail 3, and its rotation axis is perpendicular to the axis of the primary linear slide rail 3. The guide wheel 8 can roll into contact with the bottom of the secondary linear slide rail 30. Therefore, it can be understood that during the sliding and extension process of the secondary linear slide rail 30 along the primary linear slide rail 3, the guide wheel 8 plays a role in assisting the sliding of the secondary linear slide rail 30.

[0045] In this embodiment, refer to Figure 2 , Figure 6 and Figure 7 The upper surface of the secondary linear slide rail 30 is provided with a groove 304, which extends axially along the secondary linear slide rail 30. Smooth rods 305 extending axially along the groove 304 are provided on opposite side walls within the groove 304. A pulley 20 is vertically arranged at the bottom of the helipad 2, and a groove 21 is provided circumferentially on the circumferential surface of the pulley 20 for rolling contact with the smooth rods 305. This reduces the friction between the helipad 2 and the secondary linear slide rail 30, making the helipad 2 slide more smoothly along the secondary linear slide rail 30. Furthermore, the primary linear slide rail 3 has the same structure as the secondary linear slide rail 30; that is, the sliding structure between the primary linear slide rail 3 and the secondary linear slide rail 30 is the same as the sliding structure between the helipad 2 and the secondary linear slide rail 30, which will not be elaborated here.

[0046] In this embodiment, refer to Figure 2 Both ends of the primary linear slide rail 3 are provided with limiting seats 306. During the sliding process of the secondary linear slide rail 30 along the primary linear slide rail 3, the limiting seats 306 can prevent the secondary linear slide rail 30 from disengaging from the primary linear slide rail 3.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
