Description

Technical Field

[0001] The utility model relates to a locking mechanism and a locking module suitable for an unmanned aerial vehicle (UAV) logistics support device, belonging to UAV supporting equipment. Background Art

[0002] The UAV logistics support device is not a standard configuration for UAVs. However, with the requirements of UAV large-scale and continuous operation, the importance of such devices has gradually emerged. Enterprises usually develop adapted UAV logistics support devices separately according to market demand. Due to reasons such as significant differences in the physical structure sizes of different types of UAVs, generally, a UAV logistics support device with one structure can only be adapted to one model of UAV. Moreover, for the take-off operation and recovery operation of UAVs, manual operation is required. Therefore, there are problems such as poor equipment compatibility and low integration of receiving and releasing.

[0003] The important reasons why it is difficult for UAV logistics support devices to be universal lie in the weight, structure size, interface position, etc. of UAVs. Different weights have different requirements for the load capacity of the lifting platform, etc. Different structure sizes have different requirements for the volume of the hangar body, centering mechanism, etc. Different interface positions have different requirements for charging accessories, etc. In addition, software adaptation is also an issue to be considered.

[0004] Taking all the above into consideration, when the hangar body is determined, reducing the load on the lifting platform will be able to improve its load capacity for UAVs, and thus be able to adapt to more models of UAVs; designing a fixing mechanism that can fix various types of UAVs on the lifting platform will be able to solve the positioning problem of different types of UAVs in the hangar body; the unified problem of the circuit interface can be achieved through a standardized adapter; in addition, combined with software design, the integration of functions such as the take-off operation, recovery operation, storage, and charging of multiple models of UAVs can be realized, supporting online charging, flight communication, and control of the compatible UAV models. Summary of the Utility Model

[0005] Object of the Invention: In order to overcome the deficiencies in the prior art, the utility model provides a locking mechanism and a locking module suitable for a UAV logistics support device, splitting the centering mechanism in the prior art from the lifting platform, and at the same time adding a locking mechanism to fix the UAV, improving the adaptability of the UAV logistics support device to multiple UAV models.

[0006] Technical Solution: To achieve the above object, the technical solution adopted by the utility model is as follows:

[0007] A locking mechanism applicable to a logistics support device for drones, comprising a jaw mounting plate, a pair of hinge seats, jaws, a driving motor and a pair of potentiometers. The jaw mounting plate is of a U-shaped plate structure for connecting the take-off and landing platform of the logistics support device, and the upper surface of the jaw mounting plate is flush with the upper surface of the take-off and landing platform. The hinge seats, the housing of the driving motor and the resistor body of the potentiometer are all fixed on the lower surface of the jaw mounting plate, and the two hinge seats are respectively located below the two wings of the jaw mounting plate. The jaws are of a J-shaped structure. The bent end of the jaw is the end part, and the end part is used for hooking the cross bar below the drone landing gear. The vertical end of the jaw is the root part, and each side of the root part is fixed with a hinge shaft, and the two hinge shafts are respectively installed in the two hinge seats. The jaw rotates in the notch of the jaw mounting plate, and the end part of the jaw faces outwards. The output shaft of the driving motor is connected to one of the hinge shafts through a belt drive structure, and the brushes of the two potentiometers are installed on the other hinge shaft. The two potentiometers respectively detect the open state and the locked state of the jaw. The open state is the position where the end part of the jaw rotates to below the take-off and landing platform and the root part does not protrude from the upper surface of the take-off and landing platform. The locked state is the position where the end part of the jaw rotates above the take-off and landing platform (4) to hook the cross bar below the drone landing gear to the movement limit position.

[0008] Preferably, the locking mechanisms are arranged in pairs, and the notches of the two jaw mounting plates in each pair of locking mechanisms face each other. When in use, the two jaws rotate from bottom to top and from inside to outside to respectively hook the two cross bars below the drone landing gear.

[0009] Preferably, it further comprises a shielding plate and a pair of connecting angle steels. One ends of the two connecting angle steels are respectively fixed on the lower side or the outer side of the two wings of the jaw mounting plate. The shielding plate is installed facing the notch of the jaw mounting plate, and the upper surface of the shielding plate is flush with the upper surface of the jaw mounting plate. The shielding plate is installed on the other ends of the two connecting angle steels through two hinge structures respectively. When the jaw is in the open state, the upper surface of the shielding plate is flush with the upper surface of the jaw mounting plate, covering the moving space of the jaw, playing a role in sealing and dust prevention. During the locking action of the jaw, the rotation of the jaw will push the shielding plate to rotate, which will not affect the locking function of the locking mechanism.

[0010] Preferably, the belt drive structure and the potentiometers are installed inside the two hinge seats.

[0011] In view of the requirement of the logistics support device to store various types of drones, the above-mentioned new locking mechanism is designed in this case. Through the design of the inner arc of the jaw, it can adapt to the cross bars below the drone landing gears of different sizes. Through the design of the distance between the two jaw mounting plates, it can adapt to the cross bars below the drone landing gears with different size distances, thereby improving the adaptability of the entire logistics support device to various models of drones.

[0012] A locking module suitable for a UAV logistics support device comprises a take-off and landing platform, a pair of locking mechanisms for fixing the UAV are installed on the take-off and landing platform, and a through hole for avoiding charging piles is arranged in the middle of the take-off and landing platform and between the two locking mechanisms.

[0013] Preferably, the two claw mounting plates in the two locking mechanisms are mounted on the take-off and landing platform through a pair of connecting rails, the pair of rails are fixed in parallel to the lower surface of the take-off and landing platform, the two claw mounting plates are respectively mounted on both ends of the rails through a slider structure, and the two claw mounting plates are driven by a motor to move synchronously relative to or opposite to each other. This design can further adjust the distance between the two claws, and further increase the number of drones that the entire logistics support device can adapt to.

[0014] Preferably, it also includes a centering mechanism, which includes a frame body, a pair of X-direction centering rods and a pair of Y-direction centering rods, and the X-direction centering rods and the Y-direction centering rods are installed in the frame body in a # shape; the frame body is suspended above the lifting and landing platform and is fixed relative to the fixed end of the lifting mechanism of the lifting and landing platform.

[0015] When the UAV motor stops rotating, the direction in which the blades stop is arbitrary, but when the logistics support device stores the UAV, the blades need to be moved to the specified position, so a paddle structure is needed to move the blades to the specified storage position; therefore, preferably, the centering mechanism also includes a paddle structure, which is installed on the X-axis centering rod and / or the Y-axis centering rod, and the paddle structure is a longitudinal rod that can move back and forth along the centering rod or a longitudinal rod fixed on the centering rod; when the take-off and landing platform is at the paddle height position, the UAV is parked on the lifting platform, and the top of the longitudinal rod is higher than the height of the UAV blades.

[0016] The centering mechanism is a mechanism that drives the drone that has deviated from the center of the area back to the center of the area; in the prior art, the centering mechanism is set on the take-off and landing platform, and moves with the take-off and landing platform, playing the role of centering and fixing at the same time, increasing the load of the lifting platform, making the weight range of the drone that the lifting platform can bear more limited; at the same time, the centering mechanism of the prior art is not very ideal for fixing the drone, affecting the stability and reliability of charging or maintaining the drone. In this case, the centering mechanism is separated from the take-off and landing platform, and an additional locking mechanism is added to fix the drone, which reduces the load of the take-off and landing platform as a whole and increases the weight range of the drone that the lifting platform can bear; the locking mechanism can stably and reliably fix the drone, making it convenient to charge or maintain the drone.

[0017] Beneficial effects: The locking mechanism and locking module applicable to the UAV logistics support device provided by the present utility model. Through the design of the inner arc of the claw of the locking mechanism in this case, it can adapt to the cross bars under the UAV landing gears of different sizes. Through the design of the distance between the two claw mounting plates, it can adapt to the cross bars under the UAV landing gears with different size distances, thereby improving the adaptability of the entire logistics support device to UAVs of various models; in this case, the centering mechanism is separated from the takeoff and landing platform, and at the same time, a locking mechanism is additionally added to fix the UAV, which overall reduces the load of the takeoff and landing platform and increases the weight range of UAVs that the lifting platform can bear; the locking mechanism can stably and reliably fix the UAV, facilitating the charging or maintenance of the UAV.

The top cover 2 is a pair of opening and closing structures and is installed on the top of the hangar body 1.

[0029] The takeoff and landing platform 4 is installed in the hangar body 1 through a lifting mechanism. A pair of locking mechanisms for fixing the drone are installed on the takeoff and landing platform 4. A through hole is provided in the middle of the takeoff and landing platform 4, between the two locking mechanisms. The notches of the two claw mounting plates 4-1 in the pair of locking mechanisms face each other. When in use, the two claws 4-3 rotate from bottom to top and from inside to outside, respectively hooking the two crossbars under the drone's landing gear.

[0030] As Figure 2 Shown, the locking mechanism includes a claw mounting plate 4-1, a pair of hinge seats 4-2, a claw 4-3, a drive motor 4-4, and a pair of potentiometers 4-5. The claw mounting plate 4-1 is a U-shaped plate structure for connecting the takeoff and landing platform 4 of the logistics support device, and the upper surface of the claw mounting plate 4-1 is flush with the upper surface of the takeoff and landing platform 4. The hinge seats 4-2, the housing of the drive motor 4-4, and the resistor body of the potentiometer 4-5 are all fixed on the lower surface of the claw mounting plate 4-1, and the two hinge seats 4-2 are respectively located under the two wings of the claw mounting plate 4-1. The claw 4-3 is a J-shaped structure. The bent end of the claw 4-3 is the end for hooking the crossbar under the drone's landing gear, and the vertical end of the claw 4-3 is the root. One hinge shaft is fixed on each side of the root. The two hinge shafts are respectively installed in the two hinge seats 4-2. The claw 4-3 rotates in the notch of the claw mounting plate 4-1, and the end of the claw 4-3 faces outward. The output shaft of the drive motor 4-4 is connected to one of the hinge shafts through a belt drive structure. The brushes of the two potentiometers 4-5 are installed on the other hinge shaft. The two potentiometers 4-5 respectively detect the open state and the locked state of the claw 4-3. The open state is the position where the end of the claw 4-3 rotates below the takeoff and landing platform 4 and the root does not protrude from the upper surface of the takeoff and landing platform 4. The locked state is the position where the end of the claw 4-3 rotates above the takeoff and landing platform 4 to hook the crossbar under the drone's landing gear to the movement limit position.

[0031] As Figure 3As shown, the centering mechanism 3 is arranged on the inner wall of the hangar body 1, independent of the take-off and landing platform 4, and located below the top cover 2. The centering mechanism 3 includes a frame body 3-1, a pair of X-direction centering rods 3-2, a pair of Y-direction centering rods 3-3 and a paddle structure 3-4. The frame body 3-1 is installed on the inner wall of the hangar body 1, and is located in the area between the highest position of the take-off and landing platform 4 and the top cover 2. The X-direction centering rod 3-2 and the Y-direction centering rod 3-3 are installed in the frame body 3-1 in a # shape; the centering rod and the centering motor are connected by a synchronous belt and a synchronous pulley, and the two centering rods on the opposite side are connected by a synchronous belt and driven by the same stepping motor; the paddle structure 3-4 is installed on the X-direction centering rod 3-2 or the Y-direction centering rod 3-3. The paddle structure 3-4 is a longitudinal rod fixed on the centering rod. When the take-off and landing platform 4 is at the paddle height position, the UAV is parked on the lifting platform 4, and the top of the longitudinal rod is higher than the height of the UAV blades. As shown Figure 4 As shown, when the UAV lands on the take-off and landing platform 4, the four centering rods are driven by the stepper motor to move inward at the same time to push the UAV to the predetermined position; then the locking mechanism fixes the UAV, and then the four centering rods return to the initial position (as shown in FIG. Figure 5 Then the landing platform 4 is lowered to the propeller shifting height, and then the propeller shifting structure 3-4 shifts the propeller to the specified position (as shown in FIG. Figure 6 As shown), the paddle structure 3-4 then returns to the initial position, and then the landing platform 4 continues to descend to the charging position.

[0032] In the charging position, the charging port of the charging column is connected to the drone charger, and the charging copper pin of the charging port is in contact with the power receiving copper sheet of the charger. Considering the differences between various types of drones, the charging copper pin of the charging port adopts a two-level elastic structure, with a rigid copper column tube at the bottom and an elastic ejector pin inside to avoid poor contact and insufficient rigidity. Considering the problem of opening the cover on rainy days, a water guide groove is designed on the top of the charging pile to prevent water accumulation from short-circuiting the power supply copper pin.

The electrical cabinet is provided with side-opening doors on the opposite side for easy debugging.
