Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 5The utility model provides a lifting platform for a vehicle-mounted UAV, which is arranged in a carriage 1 and includes: a top cover 2, which is arranged on the top of the carriage 1 and is configured to close the opening on the top of the carriage 1; a limiting unit, which is fixed on the top of the carriage 1, and the top cover 2 and the limiting unit are slidingly matched; a lifting unit 3, which is arranged in the carriage 1, and a UAV is arranged on the top surface.

[0034] Specifically, a lifting unit 3 for placing the drone is provided in the carriage 1. The lifting unit 3 is used as a take-off and recovery platform for the drone. An opening is provided at the top of the carriage 1 for the lifting unit 3 to drive the drone to leave the carriage 1. When the drone is not in use, the opening is closed by the top cover 2 to ensure the closure of the carriage 1.

[0035] The carriage 1 is the overall rear structure of the vehicle, and the carriage 1 is installed on the front of the vehicle.

[0036] One end of the first connecting cable 4 is connected to the top cover 2, and the first connecting cable 4 is arranged along the top cover 2 and the inner wall of the car 1. The other end of the first connecting cable 4 is wrapped around the back panel surface of the lifting unit 3 and fixed to the back panel surface of the lifting unit 3. The lifting unit 3 is configured to move upward along the car 1 to drive the top cover 2 to move horizontally relative to the top of the car 1 through the first connecting cable 4 and open the opening.

[0037] Specifically, the first connecting cable 4 is arranged along the inner wall of the car body 1 to prevent the first connecting cable 4 from affecting the take-off and landing of the drone during the lifting process of the lifting unit 3. The back panel surface of the lifting unit 3 is fixed to the first connecting cable 4. During the upward movement of the lifting unit 3, the lifting unit 3 drives the first connecting cable 4 to move, and then drives the top cover 2 to move. Since the top cover 2 is limited by the limiting unit, the top cover 2 can only move horizontally relative to the car body 1 to open the top opening.

[0038] Among them, the length of the first connecting rope 4 can be determined according to actual conditions, that is, when the lifting unit 3 moves upward, the top cover 2 needs to be moved to a position where the drone does not affect the continued upward movement of the drone before it approaches the opening or is about to approach the opening, so as to avoid collision between the top cover 2 and the drone and thus damage the drone.

[0039] In this embodiment, refer to Figure 2 , Figure 3 , Figure 4 , and also includes: a first guide shaft 5, fixed to the top inner wall of the carriage 1 and located above the lifting unit 3; a second guide shaft 6, fixed to the side wall of the carriage 1 and located below the lifting unit 3; a third guide shaft 7, fixed to the side wall of the carriage 1 opposite to the second guide shaft 6, and located below the lifting unit 3, and the first connecting rope 4 is sequentially wound around the first guide shaft 5, the second guide shaft 6, and the third guide shaft 7 and fixed to the lifting unit 3.

[0040] In a specific embodiment of the utility model, the top cover 2 moves toward the direction close to the front of the vehicle to open the opening, the first guide shaft 5 is fixed on the top of the vehicle body 1 and close to the front of the vehicle, the second guide shaft 6 is fixed on the inner wall of the vehicle body close to the front of the vehicle, and the third guide shaft 7 is fixed on the inner wall of the vehicle body at the original front of the vehicle. When the top cover 2 is not opened, one end of the first connecting cable 4 is fixed at a position of the top cover 2 away from the front of the vehicle, so that the first connecting cable 4 is firstly wound around the first guide shaft 5, then through the second guide shaft 6, and finally through the third guide shaft 7 and fixed to the back panel surface of the lifting unit 3.

[0041] The side wall of the lifting unit 3 is provided with a passage for the first connecting rope 4 to pass through.

The lifting unit 3 is configured to move downward along the carriage 1 to drive the top cover 2 to move horizontally relative to the top of the carriage 1 through the second connecting cable 8 and close the opening.

[0043] Specifically, a second connecting cable 8 is connected to the top cover 2. When the drone is retracted, the lifting unit 3 moves downward to retract the carriage 1. Under the action of the second connecting cable 8, the top cover 2 can be reset to close the opening.

[0044] In this embodiment, refer to Figure 3 , Figure 4 , and also includes a fourth guide shaft 9, which is fixed to the inner wall of the top of the carriage 1 and is located above the lifting platform. The second connecting rope 8 is wound around the fourth guide shaft 9 and fixed to the top surface of the lifting unit 3.

[0045] The fourth guide shaft 9 is arranged corresponding to the first guide shaft 5, so that the first guide shaft 5, the second guide shaft 6, the third guide shaft 7, and the fourth guide shaft 9 form a similar rectangular arrangement structure. On the basis of ensuring that the movement of the lifting unit 3 drives the movement of the top cover 2, the first connecting cable 4 and the second connecting cable 8 are prevented from affecting the drone.

[0046] In this embodiment, refer to Figure 1 , Figure 2 , and also includes a driver 10, which is fixed in the carriage 1 and located below the lifting unit 3, and the movable end of the driver 10 is fixed to the lifting unit 3.

[0047] Specifically, the fixed end of the driver 10 is fixed in the carriage 1 , and the movable end of the driver 10 can be extended and retracted along the carriage 1 to drive the lifting unit 3 to rise and fall.

[0048] The driver 10 is a driving device such as an electric telescopic rod, a hydraulic telescopic rod, etc.

[0049] In this embodiment, refer to Figure 1 , Figure 2 , and also includes at least one pair of limit rails 11 fixed on the inner wall of the carriage 1, and the lifting unit 3 is in limited sliding cooperation with the limit rails 11.

[0050] Specifically, the limiting rail 11 is used to limit the lifting unit 3 to ensure that the lifting unit 3 moves along a preset direction.

[0051] In this embodiment, refer to Figure 3 , Figure 4 The limiting unit includes: a pair of transverse braces 12, which are arranged in the opening and fixed to the carriage 1; a slide 13, which is slidably connected to the transverse brace 12, the slide 13 is fixed to the top cover 2, and one end of the first connecting cable 4 and one end of the second connecting cable 8 are respectively fixed to the slide 13.

[0052] Specifically, a pair of cross braces 12 are arranged on both sides of the opening, and the space between the pair of cross braces 12 is used for the passage of drones. The slide 13 is sleeved on the cross braces 12 to ensure that the top cover 2 is limited during movement. The slide 13 is away from the front of the vehicle. The first connecting cable 4 is fixed to the front end surface of the slide 13 close to the front of the vehicle, and the second connecting cable 8 is fixed to the rear end surface of the slide 13 away from the front of the vehicle.

[0053] In this embodiment, refer to Figure 5 , and also includes a distance adjusting cylinder 14, which is respectively arranged on the first connecting rope 4 and the second connecting rope 8.
