Description

Technical Field

[0001] This utility model relates to the field of drone transportation, and in particular to a drone transport vehicle and its drone take-off and landing device. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly being used in aerial photography, inspection, surveying, and emergency rescue. To facilitate the take-off, landing, and storage of drones, various drone take-off and landing devices have emerged.

[0003] Existing drone take-off and landing devices typically include a landing platform for carrying the drone and a sliding mechanism for guiding and supporting the movement of the landing platform. The sliding mechanism usually employs two mirror-image pulley-type rails, each consisting of a first rail and a second rail. One of the first or second rails is mounted on the landing platform, while the other is mounted on the chassis of a transport vehicle, allowing for relative sliding between the landing platform and the chassis. In this structure, the second rail has a connector that supports a rotatable pulley. The pulley extends into a groove in the first rail and slides against the upper wall of the groove, rotating as the landing platform moves. Due to manufacturing tolerances and assembly factors, there is a certain lateral clearance between the side wall of the groove and the connector. When the transport vehicle encounters bumps, turns, or braking during operation, this clearance causes the landing platform to wobble or sway horizontally. This swaying is transmitted to the drone parked on the landing platform, causing it to shake. If the clearance is too large, it may even lead to the drone tipping over or colliding. Utility Model Content

[0004] Therefore, it is necessary to provide a drone transport vehicle and its drone take-off and landing device to solve the problem that excessive clearance in the sliding mechanism can cause the drone to tip over.

[0005] To achieve the above objectives, the inventors provide a drone take-off and landing device, comprising: a landing plate and a sliding mechanism;

[0006] The landing pad is for parking drones;

[0007] The sliding mechanism includes two side-by-side slide rails. Each slide rail includes a first rail body, a second rail body, a connector, a first sliding member, a second sliding member, and a gap adjustment assembly. The first rail body has a groove, and the second rail body is located on one side of the first rail body. Either the second rail body or the first rail body is mounted on the lifting plate. The connector is mounted on the second rail body and supports the first and second sliding members. The first sliding member is slidably connected to the upper wall of the groove, and the second sliding member is slidably connected to the side wall of the groove. The connector has a first accommodating cavity inside, and the second sliding member is located in the first accommodating cavity. The gap adjustment assembly is mounted on the connector and connected to the second sliding member to adjust the gap between the second sliding member and the side wall of the groove.

[0008] Furthermore: the connector has a second accommodating cavity inside, the second accommodating cavity has an internal thread, the gap adjustment assembly includes a first stud, the first stud is threadedly connected to the internal thread of the second accommodating cavity, and the first stud abuts against the housing of the second sliding member.

[0009] Furthermore, the gap adjustment assembly further includes a second stud, which is threadedly connected to the internal thread of the second accommodating cavity. The second stud is located on the side of the first stud away from the second sliding member, and the second stud abuts against the first stud.

[0010] Furthermore: the second sliding member is a pulley, the housing of the second sliding member supports a rotatable wheel, the housing is sleeved in the first accommodating cavity, and the second sliding member is slidably connected to the side wall of the slide groove through the wheel.

[0011] Furthermore: the first sliding member is a pulley, the first sliding member is disposed on the connecting member, and can rotate relative to the connecting member.

[0012] Furthermore, the second rail body is provided with a plurality of connecting members arranged along the sliding direction of the lifting plate.

[0013] Furthermore, the sliding mechanism also includes a sliding telescopic rod, which is connected to the lifting plate and is used to drive the lifting plate to slide along the slide rail.

[0014] Furthermore, it also includes a limiting member, which is used to limit the sliding stroke of the lifting plate along the slide rail.

[0015] Furthermore: the limiting member is a limiting plate, which is located on the same end of the two slide rails and can abut against the end of the lifting plate.

[0016] To achieve the above objectives, the inventors also provide a drone transport vehicle, including a drone take-off and landing device as described in any of the above embodiments.

[0017] Unlike existing technologies, the above technical solution has the following beneficial effects:

[0018] The gap adjustment assembly allows for adjustment of the position of the second sliding member, maintaining a slight contact preload or minimal gap between the second sliding member and the sidewall of the chute. This prevents significant lateral displacement of the lifting platform even on bumpy roads, effectively suppressing swaying.

[0040] Please see Figures 1 to 5 This embodiment provides a drone take-off and landing device, including: a take-off and landing plate 2 and a sliding mechanism 1;

[0041] Landing platform 2 provides parking for drones;

[0042] The sliding mechanism 1 includes two slide rails 11 arranged side by side. Each slide rail 11 includes a first rail body 111, a second rail body 112, a connecting member 113, a first sliding member 114, a second sliding member 115, and a gap adjustment assembly 110. The first rail body 111 is provided with a sliding groove 117. The second rail body 112 is located on one side of the first rail body 111. Either the second rail body 112 or the first rail body 111 is mounted on the lifting plate 2. The connecting member 113 is mounted on the second rail body 112 and supports the first sliding member 114 and the second sliding member 115. Two sliding members 115, the first sliding member 114 is used to slide and connect with the upper wall of the slide groove 117, and the second sliding member 115 is used to slide and connect with the side wall of the slide groove 117. The connector 113 has a first receiving cavity 118 and a second receiving cavity 119 inside. The second sliding member 115 is disposed in the first receiving cavity 118. The gap adjustment assembly 110 is disposed in the second receiving cavity 119 and connected to the second sliding member 115, and is used to adjust the gap between the second sliding member 115 and the side wall of the slide groove 117.

[0043] In actual installation, one of the first rail body 111 or the second rail body 112 is mounted on the lifting platform 2, while the other is mounted on the chassis 4 of the transport vehicle, such as... Figures 1 to 3 As shown, this allows the lifting platform 2 to move relative to the vehicle body. There are two installation methods for the second rail 112 or the first rail 111: the first is that two second rails 112 are installed on the chassis 4 of the transport vehicle, and two first rails 111 are installed on the lifting platform 2; the second is that two first rails 111 are installed on the chassis 4 of the transport vehicle, and two second rails 112 are installed on the lifting platform 2. For example... Figure 1 , Figure 2 As shown, the first rail 111 is installed at the bottom of the lifting platform 2, and the second rail 112 is installed on the chassis 4 of the transport vehicle. The two first rails 111 and the two second rails 112 are arranged symmetrically from left to right, with the two first rails 111 positioned between the two second rails 112, forming a left-right mirrored sliding mechanism 1. This arrangement ensures that the lifting platform 2 experiences balanced forces during forward and backward movement, operates smoothly, and possesses good guidance and structural stability.

[0044] The first sliding member 114 is a rotatable roller, ball, or slider, which slides in contact with the upper wall of the slide groove 117 and bears the vertical load of the lifting plate 2. The second sliding member 115 is a rotatable roller, ball, or slider, used for sliding contact with the side wall of the slide groove 117. Although the first sliding member 114 and the second sliding member 115 are mounted on the same connecting member 113, their structures may differ. When both the first sliding member 114 and the second sliding member 115 are pulleys, Figure 5 As shown, the axis of the second slider 115 is vertical, and the second slider 115 protrudes from the first receiving cavity 118. The axis of the first slider 114 is horizontal, and the first slider 114 is located outside the second slider 115.

[0045] The gap adjustment assembly 110 can adjust the position of the second sliding member 115, so that the second sliding member 115 maintains a slight contact preload or a very small gap with the side wall of the slide groove 117. In this way, even under bumpy road conditions, the lifting plate 2 will not produce significant lateral displacement, effectively suppressing swaying.

[0046] Please see Figure 5 In some embodiments, the connector 113 further includes a second receiving cavity 119 with internal threads. The gap adjustment assembly 110 includes a first stud 1101, which is threadedly connected to the internal threads of the second receiving cavity 119. The first stud 1101 abuts against the housing 116 of the second sliding member 115. During assembly, rotating the first stud 1101 can push the second sliding member 115 to move horizontally within the first receiving cavity 118. As the first stud 1101 gradually screws into the second receiving cavity 119, its end applies a thrust to the housing 116 of the second sliding member 115, causing the second sliding member 115 to move toward the side wall of the groove 117.

[0047] Please see Figure 5 In some embodiments, the gap adjustment assembly 110 further includes a second stud 1102, which is threadedly connected to the internal thread of the second receiving cavity 119. The second stud 1102 is located on the side of the first stud 1101 away from the second sliding member 115, and abuts against the first stud 1101. First, the first stud 1101 is rotated to push it inward until the second sliding member 115 reaches the required preload. Then, the second stud 1102 is screwed in so that its end is tightly against the outer end of the first stud 1101. At this time, the second stud 1102 can apply a reverse support force to the first stud 1101, restricting it from unscrewing under vibration, thereby achieving reliable mechanical locking.

[0048] Please see Figure 4 and Figure 5 In some embodiments, the second slider 115 is a pulley, and the housing 116 of the second slider 115 supports a rotatable wheel. The housing 116 is fitted into a receiving cavity, and the second slider 115 is slidably connected to the side wall of the slide groove 117 through the wheel.

[0049] Please see Figure 4 and Figure 5 In a preferred embodiment, the first sliding member 114 is a pulley, which is disposed on the connecting member 113 and can rotate relative to the connecting member 113. Specifically, the connecting member 113 is usually in the shape of a round rod, and the first sliding member 114 can be sleeved on the outer wall of the connecting member 113 through a bearing and can rotate around the connecting member 113.

[0050] Please see Figure 3 and Figure 4 In some embodiments, the second track 112 is provided with a plurality of connecting members 113 arranged along the sliding direction of the lifting plate 2. Each connecting member 113 is provided with a first sliding member 114 and a second sliding member 115. The number of connecting members 113 is determined according to the length of the lifting plate 2 and the load size, for example, two, three, four, ten or more.

[0051] Please see Figure 3 In some embodiments, the sliding mechanism 1 further includes a sliding telescopic rod 12, which is connected to the lifting plate 2 and is used to drive the lifting plate 2 to slide along the slide rail 11. The sliding telescopic rod 12 is a linear motion component that can be actively extended and retracted. One end of it can be hinged to the lifting plate 2 through a connecting seat, and the other end can be connected to the chassis 4 through another connecting seat. The sliding telescopic rod 12 is arranged along the sliding direction of the lifting plate 2, and the lifting plate 2 slides along the slide rail 11 as the sliding telescopic rod 12 extends and retracts.

[0052] Please see Figure 3 In some embodiments, the sliding telescopic rod 12 is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. The sliding telescopic rod 12 can be electrically connected to the control system to achieve automated and intelligent control of its movement. The hydraulic cylinder is supplied with pressurized oil by a hydraulic pump station, and the extension and retraction of the piston rod are controlled by an electromagnetic directional valve. The pneumatic cylinder uses compressed air as a power source, and the airflow direction is controlled by an electromagnetic valve to drive the extension and retraction of the piston rod. The electric actuator integrates a DC motor, a reduction gearbox, and a lead screw / nut transmission mechanism. The rotation of the motor drives the lead screw to move, thereby achieving smooth extension and retraction of the actuator.

[0053] In some embodiments, the drone take-off and landing device further includes a limiting member for restricting the sliding travel of the landing plate 2 along the slide rail 11. When the landing plate 2 slides back and forth along the slide rail 11 under the drive of the sliding telescopic rod 12, its movement trajectory is guided and constrained by the slide rail 11. As the movement approaches a preset end point of travel, the edge on the landing plate 2 gradually approaches the limiting member. When the two come into contact, the limiting member prevents the landing plate 2 from continuing to move.

[0054] Please see Figure 3 In some embodiments, the limiting member is a limiting plate 3, which is disposed on the same end of the two slide rails 11 and can abut against the end of the lifting plate 2. The limiting plate 3 is a rigid plate-like structure that spans across the same end of the two slide rails 11 arranged in a left-right mirror configuration, i.e., the front end or the rear end. Preferably, the lifting plate 2 moves back and forth under the drive of the sliding telescopic rod 12, and the limiting member limits the lifting plate 2 in front of it. In other embodiments, the limiting plate 3 can be located on the outside of the slide rails 11 and fixed to the chassis 4 of the transport vehicle.

[0055] In some other embodiments, the limiting member may be an elastically cushioned structure, including a metal support and an elastic buffer head (such as a rubber pad, polyurethane block, or spring buffer).

[0056] Please see Figure 2 This embodiment also provides a drone transport vehicle, including a drone take-off and landing device as described in any of the above embodiments. The chassis 4 of the drone transport vehicle carries the drone take-off and landing device, for example, the second rail 112 and the sliding telescopic rod 12 are mounted on the chassis 4.

[0057] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
