Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) launching, and in particular to a UAV launching vehicle. Background Art

[0002] At present, the field of drones is in a period of vigorous development, and various technologies surrounding drones are emerging one after another. With the full opening of the domestic low-altitude field, the high-tech achievements of drones that were once sealed in the military field are increasingly being applied to the civilian field. They are widely used in aerial photography, environmental monitoring, reconnaissance and patrol, plant protection, entertainment, component networks, firefighting and other fields.

[0003] It is known that when launching certain specific drones, such as fire-fighting drones, they need to form a specific angle with the ground according to actual conditions, that is, a lifting device is required to drive the launch box to rotate to a certain angle relative to the bottom of the transport vehicle's cabin, and then the drone is launched through the ejection system.

[0004] However, the existing Chinese patent with publication number CN110562476A discloses a vehicle-mounted UAV launch equipment, which specifically discloses a cabin, a transport vehicle and an ejection frame (launch box), wherein the ejection frame is fixed to the bottom wall of the rear cover plate, and one end of the linear telescopic part is hinged to the loading platform of the transport vehicle, and the other end is hinged to the bottom wall of the ejection frame. Although the equipment can drive the rear cover to open while adjusting the angle of the ejection frame, and although it eliminates the power mechanism for driving the cover to tilt at an angle in the traditional sense, thereby reducing the auxiliary time for UAV launch, the equipment still has the following shortcomings: 1. Referring to Figure 11 of the equipment, when the ejection frame needs to have a large elevation angle to launch the UAV, the linear telescopic part collides with the tail end of the bottom wall of the ejection frame, causing damage; 2. When the ejection frame launches the UAV, the tail end of the ejection frame is in a suspended state and lacks axial support. The ejection frame is easily affected by the recoil and its position is unstable, affecting the accuracy of the UAV launch; 3. When the ejection frame launches the UAV, the rear cover and the front cover of the cabin are subjected to a large reaction force, so the cabin requires a large strength, which is not conducive to cost saving.

[0005] To this end, we designed a vehicle-mounted drone launch device. Summary of the invention

[0006] In order to overcome the deficiencies in the background technology, the present invention discloses a UAV launching vehicle.

[0007] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: A UAV launch vehicle comprises a transport vehicle, a cabin, a launch box and a telescopic device, wherein the cabin has a front top plate and a rear top plate, the bottom of the launch box at the rear end is correspondingly hinged to the bottom of the cabin, the fixed end of the telescopic device is correspondingly hinged to the bottom of the cabin, and the telescopic end is correspondingly hinged to the bottom of the front end of the launch box, so that the connection between the launch box and the cabin, the connection between the telescopic device and the cabin, and the connection between the telescopic device and the launch box form a triangle; The top of the head end of the launch box is provided with a pressing wheel capable of pressing the bottom surface of the rear top plate, so as to drive the rear top plate to open when the launch box is in elevation; the lower end of the connecting rod is hinged correspondingly to the position near the tail end of the top of the launch box, and the bottom surface of the rear top plate is provided with a limiting slide rail correspondingly connected to the upper end of the connecting rod along the front-to-back direction, so as to limit the front-to-back position of the upper end of the connecting rod, thereby limiting the elevation angle of the launch box; Preferably, the limiting slide rail is provided with a strip groove along its length direction, and the upper end of the connecting rod is provided with a roller that cooperates with the strip groove.

[0008] Preferably, a first adjusting device for adjusting the position of the launch box and the telescopic device is also provided at the bottom of the cabin; wherein the bottom of the rear end of the launch box and the fixed end of the telescopic device are correspondingly hinged to the adjusting part of the first adjusting device.

[0009] Preferably, a support member for supporting the tail end of the launch box is provided at the bottom of the cabin, located on the side of the tail end of the launch box away from the telescopic device; a second adjustment device for adjusting the position of the support member is also provided at the bottom of the cabin, so as to adjust the position of the support member to adapt to different elevation angles of the launch box.

[0010] Preferably, the adjustment device comprises a fixed rail arranged at the bottom of the cabin along the front-rear direction, and the fixed rail is slidably connected to a movable rail along its length direction; The adjusting device also includes an adjusting mechanism for adjusting the position of the movable rail.

[0011] Preferably, the adjustment mechanism comprises a rack provided at the bottom of the movable rail along the length direction and a bearing seat fixed to the fixed rail, and the bearing seat is rotatably connected to a gear meshing with the rack; The adjustment mechanism also includes a motor drivingly connected to the gear axle.

[0012] Preferably, the opposite surfaces of the fixed rail and the movable rail are both provided with sliding grooves, and the sliding groove in the fixed rail corresponds to the sliding groove in the movable rail to form a matching cavity.

[0013] Preferably, the matching cavity is provided with at least two pulley pairs at intervals along its length direction, and two pulleys in the pulley pair are respectively located in the slide groove in the fixed rail and the slide groove in the movable rail.

[0014] Preferably, a spring telescopic rod is provided between the axles of adjacent pulley pairs.

[0015] Preferably, the support member includes a column and a support beam, the lower end of the column is arranged on the adjustment part of the second adjustment device, and the middle part of the support beam is hinged to the upper end of the column.

[0016] Due to the adoption of the above-mentioned technical solution, the present invention has the following beneficial effects: 1. The setting of the connecting rod and the limit slide rail. When the upper end of the connecting rod moves to the limit position at the front end of the limit slide rail, the upper end of the connecting rod cannot move forward any further, so that the launch box no longer moves in elevation. This can effectively prevent the launch box from having an elevation angle that is too large, causing the tail end of the launch box to collide and be damaged, thereby improving the safety factor. 2. The first adjusting device is set up so that the motor drives the gear to rotate and drive the moving rail to move, thereby driving the launch box and the telescopic device to move to the cabin door, making it convenient for the staff to inspect the tail end of the launch box; 3. The arrangement of the connecting rod, the limit slide rail and the first adjusting device can effectively prevent the first adjusting device from continuing to drive the launch box forward when the upper end of the connecting rod moves to the limit position at the front end of the limit slide rail, causing the rear end of the launch box to collide and be damaged, thereby improving the safety factor; 4. The support member and the second adjusting device are arranged so that the support member can be driven to move by the second adjusting device, so that the support member supports the tail end of the launch box at different elevation angles, bears the recoil force when the launch box launches the UAV, and ensures the stability of the launch box when launching the UAV; 5. The setting of the support member can adapt to the launch box with different elevation angles by rotating the support beam, so that the support area of ​​the tail end of the launch box by the support member is a surface, making the launch box more stable when launching the UAV, and will not cause the position of the tail end of the launch box to be concave; 6. The arrangement of the matching cavity and the roller pair can replace the sliding match between the fixed rail and the movable rail by the rolling match between the roller in the roller pair and the corresponding slide groove, thereby reducing the friction coefficient, thereby making the driving force required for the movable rail to move smaller, which is conducive to reducing costs and energy consumption; 7. The setting of the spring telescopic rod can prevent the distance between two adjacent rollers from being too close, which makes the support points of the moving rail too concentrated and affects the stability of the moving rail.

In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application and are for the convenience of describing the present invention; it should be understood that if there are terms such as "end", "side", "end portion", "lateral", "lateral", "transverse", "longitudinal", etc. indicating directions or positional relationships, they only correspond to the length and width of the corresponding components, that is, the "end portion" indicates the head and tail areas in the length direction of the corresponding component, and the "side portion" indicates the head and tail areas in the width direction of the corresponding component; this is for the convenience of describing the present invention and is not to indicate or imply that the device or element referred to must have a specific direction.

[0020] Embodiment 1, in combination with the attached Figure 1-4 A UAV launch vehicle includes a transport vehicle 1, a cabin 2, a launch box 3 and a telescopic device 4. The cabin 2 has a front top plate 2-1 and a rear top plate 2-2. Specifically, the front end of the rear top plate 2-2 is hinged to the rear end of the front top plate 2-1. By opening the rear top plate 2-2, the head end of the launch box 3 after the elevation angle is unobstructed.

[0021] The bottom of the rear end of the launch box 3 is hinged to the bottom of the cabin 2, the fixed end of the telescopic device 4 is hinged to the bottom of the cabin 2, and the telescopic end is hinged to the bottom of the head end of the launch box 3, so that the connection between the launch box 3 and the cabin 2, the connection between the telescopic device 4 and the cabin 2, and the connection between the telescopic device 4 and the launch box 3 form a triangle; that is, the launch box 3 can be driven to rotate by the extension of the telescopic device 4, thereby realizing the function of adjusting the elevation angle of the launch box 3.

[0022] Specifically, the rear end of the launch box 3 is located in front of its front end, that is, the rear end of the launch box 3 is closer to the front of the transport vehicle 1 than the front end thereof.

[0023] A pressing wheel 3-1 capable of pressing the bottom surface of the rear top plate 2-2 is provided at the top of the head end of the launch box 3, so as to drive the rear top plate 2-2 to open when the launch box 3 moves at an elevation angle; that is, when the launch box 3 rotates, since the bottom of the rear end of the launch box 3 is connected to the bottom of the cabin 2, the top of the head end of the launch box 3 moves upward toward one side of its rear end, thereby driving the pressing wheel 3-1 to press the rear top plate 2-2 upward, so that the rear top plate 2-2 opens, so that the head end of the launch box 3 after the elevation angle is unobstructed.

[0024] The lower end of the connecting rod 5 is hinged at the position near the tail end of the top of the launch box 3, and the bottom surface of the rear top plate 2-2 is provided with a limiting slide rail 2-3 corresponding to the upper end of the connecting rod 5 along the front-to-back direction, so as to limit the front-to-back position of the upper end of the connecting rod 5, and then limit the elevation angle of the launch box 3. Specifically, the lower end of the connecting rod 5 is located in front of its upper end, that is, the lower end of the connecting rod 5 is closer to the front of the transport vehicle 1 than its upper end. That is, when the launch box 3 makes an elevation movement, the lower end of the connecting rod 5 moves, and the upper end of the connecting rod 5 moves forward relative to the limiting slide rail 2-3. When the upper end of the connecting rod 5 moves to the limit at the front end of the limiting slide rail 2-3, the upper end of the connecting rod 5 cannot continue to move forward, and the posture of the connecting rod 5 no longer changes, so that the launch box 3 no longer continues to make elevation movement, which can effectively prevent the launch box 3 from making too large an elevation angle, causing the tail end of the launch box 3 to collide, causing damage to the tail end of the launch box 3, and improving the safety factor.

[0025] Furthermore, the limiting slide rail 2-3 is provided with a strip groove 2-31 along its length direction, and the upper end of the connecting rod 5 is provided with a roller 6 that cooperates with the strip groove 2-31; this can effectively improve the smoothness of the cooperation between the upper end of the connecting rod 5 and the limiting slide rail 2-3.

[0026] As required, two limiting slide rails 2-3 and connecting rods 5 are symmetrically arranged on the left and right.

[0027] Embodiment 2, combined with the attached Figure 6-9, a UAV launching vehicle, based on the first embodiment, a first adjusting device 7 for adjusting the positions of a launching box 3 and a telescopic device 4 is further provided at the bottom of the cabin 2; wherein the bottom of the tail end of the launching box 3 and the fixed end of the telescopic device 4 are both correspondingly hinged to the adjusting part of the first adjusting device 7.

[0028] As required, the first adjusting device 7 includes a fixed rail 10 arranged at the bottom of the cabin 2 along the front-rear direction, and the fixed rail 10 is slidably connected to a movable rail 11 along its length direction; The first adjusting device 7 also includes an adjusting mechanism 12 for adjusting the position of the movable rail 11. That is, the movable rail 11 can be driven to move by the adjusting mechanism 12, thereby driving the launch box 3 and the telescopic device 4 to move to the door of the cabin 2, which facilitates the staff to inspect the tail end of the launch box 3.

[0029] In this embodiment, the front end of the side of the shelter 2 is provided with a door.

[0030] According to the needs, two sets of fixed rails 10 and movable rails 11 can be provided symmetrically on the left and right.

[0031] In a possible implementation, the adjustment mechanism 12 includes a rack 12-1 provided at the bottom of the movable rail 11 along the length direction and a bearing seat 12-2 fixed to the fixed rail 10, the bearing seat 12-2 is rotatably connected to a gear 12-3 meshing with the rack 12-1; the adjustment mechanism 12 also includes a motor (not shown in the figure) drivingly connected to the axle of the gear 12-3. That is, the gear 12-3 can be driven to rotate by the motor, and since the rack 12-1 meshes with the gear 12-3, the rack 12-1 moves, and the rack 12-1 drives the movable rail 11 to move, thereby realizing the function of adjusting the position of the launch box 3.

[0032] As required, the motor is driven and connected to the gear 12-3 through the worm gear reducer 12-4.

[0033] In this embodiment, the motor and the bearing seat 12 - 2 can be directly installed on the cabin 2 .

[0034] In a possible implementation, the adjustment mechanism 12 includes a rack 12-1 provided at the bottom of the fixed rail 10 along the length direction and a bearing seat 12-2 fixedly mounted on the movable rail 11, and the bearing seat 12-2 is rotatably connected to a gear 12-3 meshing with the rack 12-1; the adjustment mechanism 12 also includes a motor connected to the axle of the gear 12-3. As needed, the motor and the gear 12-3 are connected through a worm gear reducer 12-4. That is, the motor can drive the gear 12-3 to rotate, and since the rack 12-1 meshes with the gear 12-3, the gear 12-3 moves, and the gear 12-3 drives the movable rail 11 to move, thereby realizing the function of adjusting the position of the launch box 3.

[0035] In this embodiment, when the launch box 3 moves forward, when the upper end of the connecting rod 5 moves to the limit position at the front end of the limiting slide rail 2-3, the upper end of the connecting rod 5 cannot continue to move forward, and the posture of the connecting rod 5 no longer changes, so that the launch box 3 no longer continues to move forward, which can effectively prevent the rear end of the launch box 3 from colliding with the front end plate of the cabin 2, causing damage to the rear end of the launch box 3, thereby improving the safety factor.

[0036] As required, a braking device for fixing the position of the movable rail 11 may be installed in the shelter 2 to ensure the stability of the position of the movable rail 11 when the movable rail 11 does not need to move.

[0037] Embodiment 3, in combination with the attached Figure 5-6 , a UAV launching vehicle, based on the first embodiment, a support member 8 for supporting the tail end of the launching box 3 is provided at the bottom of the cabin 2 at the side of the tail end of the launching box 3 away from the telescopic device 4; a second adjusting device 9 for adjusting the position of the support member 8 is also provided at the bottom of the cabin 2, so as to adjust the position of the support member 8 to adapt to different elevation angles of the launching box 3.

[0038] As required, the second adjusting device 9 adopts the same structure as the first adjusting device 7, and the difference lies only in the installation position, which will not be described in detail here.

[0039] As required, two sets of fixed rails 10 and movable rails 11 in the second adjusting device 9 can be symmetrically provided on the left and right.

[0040] In this way, the second adjusting device 9 can drive the support member 8 to move, so that the support member 8 can adapt to the launch box 3 with different elevation angles.

[0041] According to the needs, the support member 8 includes a column 8-1 and a support beam 8-2, the lower end of the column 8-1 is arranged at the adjustment part of the second adjustment device 9, and the middle part of the support beam 8-2 is correspondingly hinged to the upper end of the column 8-1. That is, the launch box 3 with different elevation angles can be adapted by the rotation of the support beam 8-2, so that the supporting area of ​​the rear end of the launch box 3 supported by the support member 8 is a surface, so that the launch box 3 is more stable when launching the drone.

[0042] Embodiment 4, in combination with the attached Figure 7-8 , a UAV launch vehicle, based on the second embodiment, the fixed rail 10 and the movable rail 11 are provided with slide grooves on the opposite surfaces, and the slide groove in the fixed rail 10 and the slide groove in the movable rail 11 form a matching cavity corresponding to each other; the matching cavity is provided with at least two pulley pairs 13 at intervals along its length direction, and the two pulleys in the pulley pair 13 are respectively located in the slide groove in the fixed rail 10 and the slide groove in the movable rail 11. That is, the sliding fit between the fixed rail 10 and the movable rail 11 can be replaced by the rolling fit between the pulleys in the pulley pair 13 and the corresponding slide grooves, which reduces the friction coefficient, thereby making the driving force required for the movement of the movable rail 11 smaller, which is conducive to reducing costs and energy consumption.

[0043] Embodiment 5, in combination with the attached Fig.10 A UAV launch vehicle, based on the fourth embodiment, a spring telescopic rod 14 is provided between the axles of adjacent pulley pairs 13. That is, the spring telescopic rod 14 can prevent the distance between two adjacent pulley pairs 13 from being too close, so that the support points of the moving rail 11 are too concentrated and the stability of the moving rail 11 is affected.

[0044] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
