Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted unmanned aerial vehicles, and in particular to a foldable vehicle-mounted unmanned aerial vehicle take-off and landing platform structure. Background Art

[0002] Vehicle-mounted drones effectively combine the flexibility of drones and the long-distance mobility of command vehicles, greatly expanding the scope of drone use. Generally speaking, vehicle-mounted drones use light passenger vehicles as the drone's operating platform, and achieve autonomous take-off and landing operations by equipping the car with a modular drone mobile airport.

[0003] For example, a vehicle-mounted UAV take-off and landing device with publication number CN220430584U buffers the impact force caused by the landing of the UAV by setting a buffer groove and multiple sets of spring buffers, so that the landing gear of the UAV is not easily damaged and the service life of the landing gear is increased. At the same time, by setting an electromagnetic suction cup and a pre-installed piece, the UAV is not easy to move when landing on the take-off and landing platform, and the stability is better.

[0004] However, the above device cannot reduce its volume when in use, making the entire device inconvenient to carry. When the user needs to frequently move the working environment or go on outdoor adventures, it is very troublesome to carry the lifting platform. Faced with the limited space inside the vehicle, the user cannot flexibly use the limited space to store drones and other equipment, resulting in great trouble every time the lifting platform is installed and placed. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the shortcomings of the prior art, the present invention provides a foldable vehicle-mounted UAV take-off and landing platform structure, which has the advantage of being able to fold the entire platform to improve space utilization. At the same time, when the entire device is in use, it can provide the user with more space to store UAVs and other equipment. When the UAV is stored inside the lifting platform, the overall posture of the UAV can be stabilized, so that when the user carries the UAV to move, the UAV will not be damaged by contact between the wings and the outside world due to the bumps of the vehicle.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a foldable vehicle-mounted UAV landing and take-off platform structure, comprising a mobile vehicle and a landing and take-off seat arranged on the mobile vehicle, wherein a lifting assembly is arranged inside the landing and take-off seat, and the lifting assembly is used to lift and lower to provide a landing and take-off platform, and an opening and closing assembly is arranged on the lifting assembly, and the opening and closing assembly is used to open and close the entire landing and take-off seat during the lifting and lowering process of the lifting assembly;

[0009] The lifting assembly includes a sliding rod symmetrically arranged inside the lifting and landing seat, a rotating plate symmetrically arranged on the sliding rod, a lifting plate movably arranged on one end of the rotating plate away from the sliding rod, a fixed block movably arranged on the sliding rod, a limit block arranged on one side of the fixed block close to the bottom of the lifting and landing seat, and an electric push rod arranged on one side of the limit block.

[0010] Preferably, fixed pallets are arranged in a row on one side of the lifting plate, a T-shaped block is arranged on the opposite side of the fixed pallet, a drone is arranged on the side of the lifting plate away from the fixed pallet, and a limiting component is arranged on the side of the lifting plate close to the drone. The limiting component is used to limit the activity of the drone when the drone is stored on the lifting plate.

[0011] Preferably, the opening and closing assembly includes a bidirectional screw movably arranged inside the lifting and lowering seat, an L-shaped support plate movably arranged on the bidirectional screw, and the L-shaped support plate and the bidirectional screw are screwed together, and also includes an opening cover plate arranged on the L-shaped support plate, and a first bevel tooth arranged on the bidirectional screw.

[0012] Preferably, a rotating rod is movably provided inside the lifting and landing seat, a second bevel tooth is provided on the rotating rod, a gear is provided on the rotating rod, and the gear is located below the second bevel tooth, a rack is provided on the side of the fixed block close to the first bevel tooth, and the rack is meshed with the gear, and a support rod is provided on one side of the rack.

[0013] Preferably, a locking plate is provided inside the L-shaped support plate, and a lifting square rod is movably provided inside the L-shaped support plate.

[0014] Preferably, the limiting assembly includes a support plate arranged on the side of the lifting plate close to the drone, a deflection plate arranged in an array on the support plate, a fixing rod arranged on the support plate, a pushing plate symmetrically arranged on the fixing rod, an embedded plate symmetrically arranged on the pushing plate, and the embedded plate is rotatably connected to the deflection plate.

[0015] Preferably, a contact rod is provided on one side of the push plate close to the opening cover plate, a fitting plate is provided inside the opening cover plate, and a spring is sleeved on the fixing rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention drives the movement of the sliding rod by the electric push rod, so that the lifting plate stored in the landing seat extends out, so that the lifting plate can be folded or unfolded according to actual conditions in a folding manner. In this process, the entire lifting platform is unfolded to ensure that the UAV has enough take-off and landing space, so that the entire lifting platform is more flexible in use and no longer subject to space limitations. At the same time, during the entire storage process, the utilization rate of the space can also be improved, and the folding and lifting of the entire lifting plate makes it more convenient to carry and transport the UAV;

[0018] 2. At the same time, during the entire process of the lifting plate extending, the opening cover closed on the lifting plate can be fully opened, and the UAV on the lifting plate can be completely exposed to the external environment. This can not only prevent the UAV placed on the top of the vehicle from being protected under the external rainy environment when the UAV is placed normally, but also prevent the UAV from being misoperated in the standby state, reducing the occurrence of accidents. At the same time, the opening of the opening cover can also release the limit of the deflection plate and the push plate set on the lifting plate on the UAV, so that the UAV can reach the normal take-off state;

[0019] 3. At the same time, the whole process can be realized by only driving the electric push rod to lift the lifting plate, which makes the whole process very simple and convenient. When the drone is stored, the set open cover will store the lifting plate and the drone together inside the landing seat. In this process, the deflection plate and the push plate can be driven to limit the legs of the drone to avoid the bumps caused by the user driving, which will cause the drone to shake randomly, resulting in collisions between the wings of the drone and surrounding objects, and damage to the wing function of the entire drone.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figures 1 to 7 , which is the first embodiment of the present invention, provides a technical solution: a foldable vehicle-mounted UAV landing and take-off platform structure, comprising a mobile vehicle 1 and a landing and take-off seat 2 arranged on the mobile vehicle 1, the landing and take-off seat 2 is a sealed shell, when the UAV 5 is in a standby state, the opening cover plate 43 can be closed with the opening of the landing and take-off seat 2, protecting the UAV 5 inside the entire landing and take-off seat 2, a lifting component 3 is arranged inside the landing and take-off seat 2, the lifting component 3 is used to lift and lower to provide a landing and take-off platform, an opening and closing component 4 is arranged on the lifting component 3, the opening and closing component 4 is used to open and close the entire landing and take-off seat 2 during the lifting and lowering process of the lifting component 3;

[0034] The lifting assembly 3 includes a sliding rod 31 symmetrically arranged inside the landing seat 2, and a rotating plate 32 symmetrically arranged on the sliding rod 31. The rotating plate 32 and the sliding rod 31 are engaged and rotated, and the other end of the rotating plate 32 is rotatably connected to the lifting plate 33. When the sliding rod 31 moves, the rotating plate 32 can be driven to push the lifting plate 33 to extend out from the landing seat 2, so that the drone 5 placed on the lifting plate 33 can be exposed from the landing seat 2.

[0035] A lifting plate 33 is movably arranged at one end of the rotating plate 32 away from the sliding rod 31, and the lifting plate 33 is used to carry the drone 5. A fixed block 34 is movably arranged on the sliding rod 31, and the fixed block 34 is used to connect the sliding rod 31 with the rack 453. The fixed block 34 and the sliding rod 31 are engaged and rotated, so that when the fixed block 34 is pushed by the electric push rod 36 to move, the sliding rod 31 engaged on the fixed block 34 can move synchronously;

[0036] The limit block 35 is arranged on the fixed block 34 near the bottom side of the landing seat 2. The limit block 35 is H-shaped. The notch provided on the limit block 35 is used to limit and engage with the notch provided on the landing seat 2, and the limit block 35 is fixedly connected to the fixed block 34. When the limit block 35 is pushed and moved by the electric push rod 36, the rotating plate 32 can be driven to rotate. Under the rotation of the rotating plate 32, the lifting plate 33 is extended out of the landing seat 2, which is convenient for the subsequent release of the UAV 5 from the lifting plate 33. The electric push rod 36 is arranged on one side of the limit block 35. There are multiple inner rods embedded inside the electric push rod 36. When the electric push rod 36 is started to push the limit block 35 to move, the multiple inner rods provided inside the electric push rod 36 can provide a sufficient pushing distance, so that the entire lifting plate 33 can reach the specified position, which is convenient for the release of the UAV 5.

[0037] The fixing plate 331 is arranged on one side of the lifting plate 33, and the fixing plate 331 is used to provide a stable supporting force when contacting with the L-shaped support plate 42, and the fixing plate 331 has a cavity inside for embedding a section of the T-shaped block 332 therein, so that when the T-shaped block 332 is engaged with the L-shaped support plate 42 and is driven to open outward, a section of the T-shaped block 332 embedded in the fixing plate 331 has a sufficient distance to support the lateral movement of the L-shaped support plate 42, and a T-shaped block 332 is arranged on the opposite side of the fixing plate 331, and the T-shaped block 332 is used to engage and slide with the groove opened in a vertical section of the L-shaped support plate 42, so that when the lifting plate 33 is lifted, the T-shaped block 332 can be vertically lifted in a vertical section of the L-shaped support plate 42, so as to prevent the lifting of the lifting plate 33 from affecting the normal opening of the L-shaped support plate 42;

[0038] A drone 5 is arranged on the side of the lifting plate 33 away from the fixed card plate 331. The drone 5 is used to be placed on the lifting plate 33, so that the user can fly the drone 5 when needed. A limiting component 6 is arranged on the side of the lifting plate 33 close to the drone 5. The limiting component 6 is used to limit the activity of the drone 5 when the drone 5 is stored on the lifting plate 33, so as to prevent the drone 5 from moving inside the lifting plate 33 due to bumps during driving.

[0039] The opening and closing assembly 4 includes a bidirectional screw 41 movably arranged inside the lifting and landing seat 2. The bidirectional screw 41 is used to rotate, thereby driving the L-shaped support plate 42 screwed on the bidirectional screw 41 to slowly open to both sides, and in the process of opening, the opening cover plate 43 is driven to move synchronously, so that the drone 5 inside the lifting plate 33 can be exposed to the external environment;

[0040] The L-shaped support plate 42 is movably arranged on the bidirectional screw 41, and the L-shaped support plate 42 is screwed to the bidirectional screw 41. When the bidirectional screw 41 rotates, the two L-shaped support plates 42 can be driven to open toward both sides. During the opening process of the L-shaped support plates 42, the lifting plate 33 limits the L-shaped support plates 42 through the fixed clamping plate 331, so that the opening cover plate 43 arranged on the L-shaped support plate 42 can move laterally relative to the lifting plate 33.

[0041] It also includes an opening cover plate 43 arranged on the L-shaped support plate 42. There are two opening cover plates 43, and the two opening cover plates 43 can completely close the opening on the landing seat 2 to prevent external rainwater from gathering into the entire landing seat 2 in the rainy season, resulting in excessive internal rainwater and thus causing damage to the parts of the drone 5. The first bevel gear 44 is arranged on the bidirectional screw 41, and the first bevel gear 44 is used to mesh with the second bevel gear 45 to transmit power.

[0042] During use, when the drone 5 needs to be released, the electric push rod 36 is started to drive the limit block 35 on the fixed block 34 to move. The movement of the limit block 35 causes the rotating plate 32 to rotate, thereby extending the lifting plate 33 folded inside the landing seat 2 from the inside. During the process of extending the lifting plate 33, the opening and closing component 4 is driven to open the opening cover 43 to expose the drone 5 placed on the lifting plate 33 to the external environment. Subsequently, during the opening process, the lifting square rod 422 movable inside the L-shaped support plate 42 and the T-shaped block 332 embedded in the fixed card plate 331 can be used to lift the lifting plate 33. When the translation distance is met, the opening cover 43 will not limit the lifting space of the opening cover 43, so that the entire lifting plate 33 is transformed from a state folded inside the landing seat 2 to an extended state, completing the lifting of the entire lifting plate 33.

[0043] Example 2

[0044] See also Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0045] A rotating rod 451 is movably provided inside the lifting and landing seat 2. The rotating rod 451 is used to support the gear 452 and the second bevel gear 45 provided thereon. The rotating rod 451 is provided with the second bevel gear 45. Under the action of meshing with the first bevel gear 44, the second bevel gear 45 transmits the rotation of the rotating rod 451 to the bidirectional screw 41 through the meshing of the two, so that the bidirectional screw 41 can drive the L-shaped support plate 42 to open to both sides. A gear 452 is provided on the rotating rod 451, and the gear 452 is located below the second bevel gear 45. The gear 452 is driven by the racks 453 provided on both sides of the gear 452 so that the gear 452 rotates, and at the same time drives the second bevel gear 45 to rotate synchronously;

[0046] A rack 453 is provided on one side of the fixed block 34 close to the first bevel gear 44, and the rack 453 is meshed with the gear 452. A support rod 454 is provided on one side of the rack 453. The support rod 454 is in direct contact with the inside of the landing seat 2. The rack 453 can be supported by the support rod 454. The fixed block 34 and the sliding rod 31 are in a locking and rotating relationship. Therefore, in order to avoid the angular deflection of the rack 453 set on the fixed block 34, the rack 453 can be supported in a parallel movement state by supporting the rack 453 by the support rod 454.

[0047] The L-shaped support plate 42 is provided with a clamping plate 421 inside, and a lifting square rod 422 is movably provided inside the L-shaped support plate 42. The lifting square rod 422 has a cavity inside, and slots are provided on both sides. One of the slots is used to form a clamping and sliding relationship between the lifting square rod 422 and the clamping plate 421 on the L-shaped support plate 42, and the other slot is used to insert the T-shaped block 332 on the fixed clamping plate 331 into the lifting square rod 422, so that when the lifting plate 33 is lifted, it will first slide inside the lifting square rod 422, and when the T-shaped block 332 slides to the top of the lifting square rod 422, it will drive the lifting square rod 422 to slide inside the L-shaped support plate 42, thereby providing sufficient lifting space.

[0048] During use, when the fixed block 34 moves, it drives the rack 453 set on one side thereof to move, and the movement of the rack 453 drives the rotating rod 451 to rotate, and at the same time, the second bevel gear 45 on the rotating rod 451 rotates, and the rotation of the second bevel gear 45 drives the meshing first bevel gear 44 to rotate, so that the bidirectional screw 41 rotates, and the rotation of the bidirectional screw 41 drives the L-shaped support plate 42 to open to both sides. During the opening process of the L-shaped support plate 42, the embedded The T-shaped block 332 engaged in the fixed card plate 331 will extend from the inside, so that the lifting of the T-shaped block 332 movably set inside the L-shaped support plate 42 will drive the lifting square rod 422 to slide inside the L-shaped support plate 42, thereby providing sufficient lifting space. When the L-shaped support plate 42 drives the open cover plate 43 to move, it will contact the limiting state of the deflection plate 62 and the push plate 64 on the drone 5 inside the lifting plate 33, so that the drone 5 can be released normally, which is convenient for the subsequent release work.

[0049] The remaining structures are the same as those of Example 1.

[0050] Example 3

[0051] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0052] The limiting assembly 6 includes a support plate 61 arranged on the side of the lifting plate 33 close to the drone 5, and a deflection plate 62 arranged in an array on the support plate 61. The deflection plate 62 is rotatably connected to the support plate 61. An embedding slot is provided on the deflection plate 62. When the deflection plate 62 is driven by the embedding plate 65 on the push plate 64 to deflect, a part of the embedded plate 65 will enter the embedding slot of the deflection plate 62, so that the entire deflection process will not be affected. The deflection of the deflection plate 62 can limit the support legs of the drone 5 and firmly limit the drone 5 at the current position.

[0053] A fixing rod 63 is arranged on the support plate 61, and a pushing plate 64 is symmetrically arranged on the fixing rod 63. The pushing plate 64 is in contact with the fitting plate 431 arranged on the opening cover plate 43 through the contact between the contact rod 641 arranged on one side and the fitting plate 431 arranged on the opening cover plate 43, so that the entire pushing plate 64 is retracted inwardly along the fixing rod 63. During the retraction process, the pushing plate 64 can push the drone 5 to the center of the lifting plate 33 to fit and clamp the drone 5. At the same time, the rotation of the embedded plate 65 arranged on the pushing plate 64 drives the deflection plate 62 to deflect, limit the support feet of the drone 5, and limit the drone 5 at the current position. An elastic rubber strip is installed on the opposite side of the pushing plate 64, so that when the pushing plate 64 pushes the drone 5, the elastic rubber strip can provide a certain buffer to prevent the pushing plate 64 from causing excessive squeezing of the drone 5, resulting in damage to the drone 5.

[0054] The embedded plate 65 is symmetrically arranged on the push plate 64, and the embedded plate 65 is rotatably connected to the deflection plate 62. The thickness of the embedded plate 65 is consistent with the thickness of the embedded slot opened on the deflection plate 62, which is used for normal swing between the embedded plate 65 and the deflection plate 62.

[0055] A contact rod 641 is provided on the push plate 64 near the open cover plate 43, and a fitting plate 431 is provided inside the open cover plate 43. The fitting plate 431 is used to squeeze the contact rod 641 by the fitting plate 431 when the open cover plate 43 contracts to close and seal the lifting plate 33, so that the push plate 64 contracts inward, thereby limiting the position of the drone 5. A spring 642 is sleeved on the fixed rod 63, and the spring 642 is located between the push plate 64 and the support plate 61. The spring 642 is used to facilitate the resetting of the push plate 64. When the open cover plate 43 is in an open state, the fitting plate 431 and the contact rod 641 are no longer in contact, so that the spring 642 resets the push plate 64, so that the push plate 64 and the deflection plate 62 release the limiting state of the drone 5, so that the drone 5 can be released normally.

[0056] During use, when the opening cover 43 is opened toward both sides of the lifting plate 33, the fitting plate 431 arranged on the opening cover 43 will continuously reduce the squeezing effect on the contact rod 641. When the pushing plate 64 on the contact rod 641 is pushed by the spring 642 to open toward the lifting plate 33, the embedded plate 65 arranged on the pushing plate 64 will drive the deflection plate 62 to reduce its inclination angle, so that the deflection plate 62 no longer contacts the support legs of the drone 5. At the same time, the movement of the pushing plate 64 will also release the squeezing effect on the side of the drone 5, so that the entire pushing plate 64 and the deflection plate 62 no longer limit the drone 5, so as to avoid the support legs of the drone 5 being blocked by the deflection plate 62 when the drone 5 is subsequently released, resulting in a take-off failure.

[0057] The remaining structures are the same as those of embodiments 1 and 2.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
