Description

Technical Field

[0001] The utility model belongs to the field of unmanned aerial vehicle fixing equipment, in particular to a vehicle-mounted unmanned aerial vehicle retracting and releasing frame. Background Art

[0002] Unmanned aircraft, also known as drones, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Due to their small size, low cost, and ease of use, drones are widely used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, and many other fields.

[0003] In actual applications, in order to avoid wasting the power of the drone, users usually use a vehicle-mounted retractable rack to load the drone on the car and transport the drone to the vicinity of the operation scene by vehicle. However, the traditional vehicle-mounted drone retractable rack is not easy to use. Users need to perform multiple operation steps in succession to load and unload the drone, which takes a lot of time. In addition, the fixing effect of common vehicle-mounted drone retractable racks is also insufficient. After the drone is loaded on the retractable rack, the bumps generated during the vehicle's driving can easily induce the displacement of the drone, resulting in the risk of damage to the drone during transportation.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] A vehicle-mounted drone retractable rack, the structure of which can be Figure 1-Figure 7 As shown in the figure, in this embodiment, the vehicle-mounted drone retracting and releasing frame includes: a mounting seat 1, a bearing seat 2 and two limit assemblies, wherein a mounting groove 11 is provided on the top surface of the mounting seat 1, the bearing seat 2 is slidably arranged inside the mounting groove 11, and two limit assemblies are movably arranged on both sides of the bearing seat 2, and a fixed gap for accommodating the drone is formed between the two limit assemblies. When in use, the mounting seat 1 is used to realize the connection between the device and the vehicle and provide an installation basis for other components in the device, the bearing seat 2 is used to provide a bearing basis for the drone, and the two limit assemblies are used to limit and fix the drone.

[0032] Figure 8 The figure is a simplified structural diagram of a common rotary-wing UAV. As shown in the figure, a common rotary-wing UAV includes: a UAV body 81, an arm 82, a rotor 83, a UAV tripod cross bar 84 and a UAV tripod vertical pole 85, wherein the arm 82 is used to realize the connection between the UAV body 81 and the rotor 83, and the UAV tripod cross bar 84 is connected to the bottom of the UAV body 81 through the UAV tripod vertical pole 85. When the UAV is in the parking state, the UAV tripod cross bar 84 and the UAV tripod vertical pole 85 will support the UAV body 81, so that the UAV can be stably parked on the bearing surface.

[0033] like Figure 6 and Figure 7As shown, in order to facilitate the fixation of the drone, the limiting assembly in this embodiment should include: a connecting seat 4, a limiting plate 5 and two connecting rods 6. A guide column 41 is provided on the bottom surface of the connecting seat 4, and an avoidance cutout 51 for accommodating the drone tripod upright 85 is provided on the limiting plate 5. Two positioning grooves 21 for accommodating the drone tripod cross bar 84 are provided on the top surface of the bearing seat 2, and two receiving holes for accommodating the connecting rods 6 are provided on the side wall of the bearing seat 2 close to the connecting seat 4. During assembly, the limiting plate 5 should be set on the top surface of the bearing seat 2, and the limiting plate 5 and the top surface of the connecting seat 4 are detachably connected by bolts. The two connecting rods 6 should be respectively set on both sides of the guide column 41, and the first end of the connecting rod 6 is slidably set inside the receiving hole, and the second end of the connecting rod 6 is hinged to the connecting seat 4.

[0034] When the drone needs to be loaded, the user can first place the drone tripod cross bar 84 inside the positioning groove 21, and then drive the two limit assemblies closer to each other, so that the device forms a Figure 1 The locking state shown. At this time, the limit plate 5 will cover the positioning groove 21, and the drone tripod stand 85 will enter the avoidance cutout 51, so that the drone is reliably fixed in the device. When the drone needs to be disassembled, the user can first move the two limit assemblies away from each other, so that the device forms a Figure 2 The unlocked state shown. At this time, the limit plate 5 will be misaligned with the positioning slot 21, so the UAV tripod cross bar 84 can smoothly disengage from the positioning slot 21, thereby facilitating the UAV to fly.

[0035] In order to facilitate the movement of the two limit assemblies, a guide groove for accommodating the guide column 41 is provided on the bottom surface of the mounting groove 11 in this embodiment. Figure 3 As shown, the guide groove includes a locking section 121, a direction-changing section 122 and an unlocking section 123 which are connected in sequence, and the distance from the locking section 121 to the fixed gap is smaller than the distance from the unlocking section 123 to the fixed gap. When the user drives the bearing seat 2 to slide from the unlocking section 123 to the locking section 121, since the distance from the locking section 121 to the fixed gap is smaller than the distance from the unlocking section 123 to the fixed gap, the process of the guide column 41 entering the locking section 121 from the unlocking section 123 will make the two limit components approach each other, so that the device forms the following Figure 4 Correspondingly, when the user drives the support seat 2 to slide from the locking section 121 to the unlocking section 123, the process of the guide column 41 entering the unlocking section 123 from the locking section 121 will cause the two limit components to move away from each other, so that the device forms the following Figure 5 Unlocked state shown.

[0036] Optionally, in order to realize the hinge connection between the connecting rod 6 and the connecting seat 4, a receiving groove 42 may be provided on the side wall of the connecting seat 4 close to the bearing seat 2, and a positioning shaft 421 whose axis is perpendicular to the bottom surface of the installation groove 11 is provided inside the receiving groove 42. Correspondingly, a connecting ring 61 may be provided on the second end of the connecting rod 6, and the connecting ring 61 is rotatably sleeved on the positioning shaft 421.

[0037] Since the connecting rod 6 and the connecting seat 4 are connected in an articulated manner, when the guide column 41 slides in the guide groove, the two connecting rods 6 can rotate relative to the connecting seat 4. In this way, the smoothness of the movement of the limit assembly can be improved, thereby ensuring that the device can smoothly switch between states.

[0038] In addition, in order to prevent the connection rod 6 from being separated from the receiving hole during use, thereby preventing the receiving hole from interfering with the movement of the connection rod 6, in this embodiment, a connection oblong hole 22 connected to the receiving hole may be provided on the side wall of the bearing seat 2 close to the connection seat 4, and a limiting ball 62 is provided at the first end of the connection rod 6. Specifically, the length direction of the connection oblong hole 22 should be parallel to the sliding direction of the bearing seat 2, and the outer diameter of the limiting ball 62 should be larger than the inner diameter of the connection oblong hole 22 and smaller than the inner diameter of the receiving hole.

[0039] When the connecting rod 6 slides inside the receiving hole due to the movement of the connecting seat 4, the limiting ball 62 can limit the extreme position of the connecting rod 6, thereby preventing the connecting rod 6 from escaping from the receiving hole. When the connecting rod 6 and the connecting seat 4 rotate relative to each other, the presence of the connecting oblong hole 22 can provide space for the rotation of the connecting rod 6, thereby preventing the degree of freedom of the connecting rod 6 from being improperly restricted.

[0040] As an optional implementation of this embodiment, in order to reduce the friction resistance between the guide column 41 and the guide groove, a rotatable guide wheel 411 should be provided on the guide column 41. When the guide column 41 slides along the guide groove, the guide wheel 411 can convert the sliding friction into rolling friction, thereby further improving the smoothness of the movement of the limit assembly.

[0041] In actual use, since the state switching of the device corresponds to the sliding action of the bearing seat 2, in order to improve the motion accuracy of the bearing seat 2, a guide column 31 may be provided on the side wall of the operating strip 3, and a wedge-shaped guide block 32 may be provided on the bottom surface of the operating strip 3. Accordingly, a guide oblong hole 111 for accommodating the guide column 31 should be provided on the side wall of the mounting groove 11, and a wedge-shaped guide groove 112 for accommodating the wedge-shaped guide block 32 should be provided on the bottom surface of the mounting groove 11.

[0042] When the bearing seat 2 slides inside the mounting groove 11, the cooperation between the guide column 31 and the guide oblong hole 111 can limit the sliding stroke of the bearing seat 2, and the cooperation between the wedge-shaped guide block 32 and the wedge-shaped guide groove 112 can guide the sliding direction of the bearing seat 2, and at the same time prevent the bearing seat 2 from separating from the mounting groove 11 during the sliding process, so that the bearing seat 2 can obtain a good sliding effect.

[0043] In addition, in order to prevent the bearing seat 2 from sliding abnormally when the device is in the locked state, a first locking screw hole 33 may be provided on the top surface of the operating strip 3, a locking bolt 7 should be provided inside the first locking screw hole 33, and a second locking screw hole 13 for accommodating the locking bolt 7 is provided on the mounting seat 1. When the device successfully enters the locked state, the user can rotate the locking bolt 7 downward so that the bottom end of the locking bolt 7 enters the second locking hole 13, thereby locking the position of the bearing seat 2.

[0044] As another optional implementation of this embodiment, in order to further facilitate the user to drive the support base 2 to slide, an operating handle 34 may be further provided on the side wall of the operating strip 3 away from the support base 2, so as to facilitate the user to grasp it.

[0045] The effects of the above scheme are described below:

[0046] This embodiment provides a vehicle-mounted drone storage and deployment rack, which can switch between a locked state and an unlocked state by sliding the support seat, so that it is convenient for users to load and unload drones. Secondly, this device can limit the drone through the cooperation of the limit plate, the positioning groove and the avoidance cutout, thereby improving the fixing effect of the drone. In addition, this device can also guide the movement of the limit assembly through the cooperation of the guide groove and the guide column, and can improve the movement smoothness of the limit assembly through the hinge structure of the connecting rod and the connecting seat, so as to smoothly perform the state switching action.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
