Description

Technical Field

[0001] The present invention relates to the technical field of UAV supporting equipment, and particularly to a multifunctional transport trailer for UAV transfer and fixation. Background Art

[0002] With the rapid development of UAV technology, UAVs are increasingly widely used in fields such as agriculture, logistics, surveying and mapping, and emergency rescue. However, the transfer and fixation of UAVs have always been a major challenge in practical applications. UAVs are usually large in size, complex in structure, and the landing gear part is relatively fragile, and it is easily affected by collisions or vibrations during the transfer process, resulting in equipment damage or performance degradation. In addition, the loading and unloading operations of UAVs usually require the cooperation of multiple people, with low efficiency, and there is a lack of effective fixation devices during transportation, further increasing the difficulty and risk of transfer.

[0003] Currently, the common UAV transfer equipment on the market is mostly simple brackets or trailers with single functions, which cannot meet the transfer requirements of UAVs in various scenarios. For example, traditional transfer equipment lacks efficient fixation devices, resulting in the UAV being prone to shaking or falling off during transportation; at the same time, the mobility and space utilization rate of the equipment are relatively low, making it difficult to adapt to complex terrains or long-distance transportation requirements. In addition, the existing equipment is usually cumbersome in loading and unloading operations and lacks automated design, increasing the workload of operators. Summary of the Invention

[0004] The present invention relates to a multifunctional transport trailer for UAV transfer and fixation, aiming to solve the problems of complex loading and unloading operations, poor fixation effect, insufficient mobility, and poor adaptability in the prior art, and provide an efficient, stable and convenient UAV transfer solution.

A guide rod is vertically provided on the reset seat, and an outer stopper block is provided at one end of the guide rod and extends into the inner jack; a locking frame for fixing the landing gear is provided on the outer wall of the long section of the outer stopper; an inner stopper block is provided at the other edge of the supporting rail opposite to the outer stopper; a stop piece is provided in the outer stopper, one end of the stop piece is provided with an inner connecting piece, and the inner connecting piece is fixedly connected to the outer stopper block. The other end of the stop piece is provided with an outer hanging plate exposed outside. A locking hole is provided on the stop piece. The stop piece can move in the outer stopper along the loading and unloading direction of the landing gear. Locking rods are respectively vertically provided at the left and right ends of the locking frame, and the locking rods are used to pass through the locking hole of the stop piece to fix the landing gear.

[0006] Optionally, evenly spaced reinforcing support rods are fixedly provided in the middle of the transfer frame. At the positions corresponding to the middle of the locking frame on the outer side walls of the left and right square pipes of the transfer frame, there are "C"-shaped ear pieces made of magnets. At the positions on the outer side walls of the left and right square pipes of the transfer frame away from the reset seat end, there are telescopic moving holes.

[0007] Optionally, it further includes: universal wheels with brakes, which are installed at the two corners at one end of the bottom of the transfer frame. At the other end of the transfer frame, there is a telescopic wheel frame that can be telescoped in the transfer frame. Fixed wheels for walking are provided on the telescopic wheel frame. The square pipes at the left and right ends of the telescopic wheel frame are respectively inserted into the square pipes at the left and right ends of the transfer frame. At the end of the transfer frame away from the telescopic wheel frame, there is a limit frame for controlling the telescopic movement of the telescopic wheel frame. At the end position of the telescopic wheel frame corresponding to the telescopic moving hole, a dial post is vertically provided, and the dial post passes through the telescopic moving hole.

[0008] Optionally, it further includes: a transfer fixing support, which is used to support and fix the transfer frame for transfer and transportation on a large vehicle. On the inner walls of the left and right side plates of the transfer fixing support, there are respectively "hui"-shaped side rails, and there are wheel axle strip holes in the side rails. The two fixed wheels are rotatably connected by a wheel axle. The end of the wheel axle of the fixed wheel protrudes outwards. The end of the wheel axle of the fixed wheel can be press-fitted and slidably clamped in the wheel axle strip hole. At the position of the side rail close to the open end of the transfer fixing support, there is a loading and unloading opening through which the wheel axle of the fixed wheel can be taken out from the wheel axle strip hole. At the middle position of the bottom plate at the open end of the transfer fixing support, there is a fixed jack. At the position corresponding to the fixed jack on the transfer frame, a fixed pin is vertically slidably provided, and the fixed pin is inserted into the fixed jack to fix the transfer frame on the transfer fixing support.

[0009] Optionally, a rail groove for the sliding insertion of the landing gear is formed on the upper end surface of the supporting rail. The two sides of the rail groove are respectively an outer stopper and an inner edge block. The edge of the inner edge block close to it is an inclined surface. An inspection groove is formed at the position of the outer stopper corresponding to the outer hanging plate. The outer hanging plate moves in the inspection groove. The outer end hole edge of the inner insertion hole is a chamfer structure convenient for the bottom rod of the landing gear to be inserted. The moving space of the stop piece in the outer stopper is the diameter distance of the locking rod. When the stop piece is far from the reset seat, the lock holes are misaligned to stop the locking rod. When the stop piece is close to the reset seat, the lock holes are aligned and the locking rod passes through to fix the landing gear on the supporting rail. A slot is formed in the middle of the outer wall of the outer stopper corresponding to the position of the lock frame, and a cross bar is arranged in the slot.

[0010] Optionally, a handle for pulling, dragging and lifting is connected between the bending parts of the left and right supporting rails. A pull handle for pulling, dragging and lifting is also arranged in the middle of the other end of the transfer rack.

[0011] Optionally, a tension spring is sleeved on the locking rod outside the outer stopper. The tension spring provides a pulling force always towards the side of the outer stopper for the locking rod. An unlocking rod is rotatably installed in the middle of the lock frame. The unlocking rod is made of iron. The lower end of the unlocking rod is a fork structure that can be inserted into the slot. When the lock frame is in the state of waiting to insert the lock, the unlocking rod hangs down naturally. When the lock frame moves inwards and the locking rod is inserted to fix the landing gear, the unlocking rod is adsorbed and fixed in the ear. When the lock frame is in the unlocking state to prevent locking, the unlocking rod is horizontally inserted into the slot to limit the position of the lock frame.

[0012] Optionally, a retaining disc is fixedly arranged on the guide rod outside the outer stopper. A first spring is sleeved on the guide rod outside the retaining disc. The first spring provides a reset thrust always towards the side of the inner insertion hole for the guide rod.

[0013] Optionally, a locking pin slides vertically on the limiting frame. The upper end of the locking pin is provided with a finger cap that is wider at the top and narrower at the bottom. The lower end of the locking pin is provided with a limiting block along the side wall of the transfer rack downwards. The lower end of the limiting block is an inclined surface structure facing the side of the telescopic wheel frame. The limiting block is used to stop the shifting column from moving towards the pull handle side. A second spring is arranged on the locking pin above the limiting block. When the telescopic wheel frame retracts into the transfer rack, the limiting block is squeezed and lifted by the shifting column. Under the action of the second spring, the limiting block resets to limit the movement of the shifting column. When the telescopic wheel frame needs to be pulled out, the finger is used to lift the finger cap upwards to drag the transfer rack, and the telescopic wheel frame is pulled out from the transfer rack.

[0014] Optionally, a hanging rod is vertically arranged at the upper end of the fixing pin. A retaining ring is fixedly arranged on the fixing pin below the transfer rack. A third spring is sleeved on the fixing pin between the retaining ring and the transfer rack. A clamping bracket is vertically arranged upwards on the transfer rack on one side of the fixing pin. The upper end of the clamping bracket is a card slot that can accommodate the hanging rod. When the hanging rod is stuck in the clamping bracket, the lower end of the fixing pin will not interfere with the transfer fixing bracket.

[0015] The present invention provides a multi-functional transport trailer for the transfer and fixation of unmanned aerial vehicles, which has the following beneficial effects:

[0016] First, in terms of the loading, unloading and fixation of the landing gear of the unmanned aerial vehicle, the arc-shaped structure of the support rail and the design of the reset seat enable the landing gear to easily slide into and be fixed on the transfer rack, significantly reducing the difficulty of loading and unloading operations. The cooperation of the outer stopper and the inner edge block ensures the stability of the landing gear during transportation, and the linkage design of the locking rack and the locking rod further enhances the fixation effect, preventing the landing gear from moving or falling off during transportation. The movable design of the stop piece enables the locking rod to automatically align with the lock hole when the landing gear is loaded, realizing the convenient operation of "push and lock". At the same time, the magnetic attraction design of the unlocking rod avoids abnormal noises generated by vibration during transportation, further improving the fixation reliability. In addition, the design of the strengthening support rod and the lug improves the overall strength and stability of the transfer rack, ensuring the durability of the trailer in complex environments.

[0017] Second, in terms of the moving and fixing functions of the trailer, in Embodiment 2, through the design of the universal wheels and the telescopic wheel frame, the flexible movement and space optimization of the trailer are realized. The universal wheels are equipped with a braking function, ensuring the stability of the trailer when parked, and the telescopic function of the telescopic wheel frame enables the trailer to save space when not in use. The cooperation design of the limit frame and the locking pin makes the telescopic operation of the telescopic wheel frame more convenient and reliable, and the automatic reset function of the second spring further improves the convenience and safety of the operation. This design makes the trailer suitable for both short-distance flexible transfer and stable parking, meeting the usage requirements in various scenarios.

[0018] Finally, in terms of the fixed transportation of the transfer rack and the low-altitude equipment transfer platform vehicle, in Embodiment 3, through the design of the transfer fixing support and the fixing pin, the stable fixation of the transfer rack on the large vehicle is realized. The design of the side rail and the wheel axle strip holes enables the fixing wheel to be conveniently installed and disassembled, and the setting of the loading and unloading port further simplifies the operation process. The fixing pin firmly fixes the transfer rack on the transfer fixing support through the fixing jack, ensuring the stability during transportation. The design of the hanging rod and the clamping bracket enables the fixing pin to be conveniently retracted when not in use, avoiding interference with the transfer fixing support, and the automatic reset function of the third spring further improves the convenience and safety of the operation.

[0019] In summary, through multi-faceted structural optimization and functional design, the present invention significantly improves the efficiency, stability and convenience of the transfer and fixation operations of unmanned aerial vehicles, is suitable for the transportation needs of unmanned aerial vehicles in various scenarios, and has broad application prospects and practical values.

On the reset seat 7, a guide rod 701 is vertically arranged. One end of the guide rod 701 is provided with an outer stopper block 704 and extends into the inner jack 3023. On the outer wall of the long section of the outer stopper 302, a lock frame 5 for fixing the landing gear 10 is provided. On the other edge of the support rail 3 opposite to the outer stopper 302, an inner stopper block 303 is provided. A stop piece 304 is arranged in the outer stopper 302. One end of the stop piece 304 is provided with an inner connecting piece 3042, and the inner connecting piece 3042 is fixedly connected with the outer stopper block 704. The other end of the stop piece 304 is provided with an outer hanging plate 3041 exposed outside. A lock hole 3043 is provided on the stop piece 304. The stop piece 304 can move in the outer stopper 302 along the loading and unloading direction of the landing gear 10. At the left and right ends of the lock frame 5, lock rods 501 are respectively vertically arranged. The lock rods 501 are used to pass through the lock hole 3043 of the stop piece 304 to fix the landing gear 10.

[0038] Among them, evenly spaced strengthening support rods 101 are fixedly arranged in the middle of the transfer frame 1. At the positions on the outer side walls of the left and right square tubes of the transfer frame 1 corresponding to the middle of the lock frame 5, "C"-shaped ear pieces 102 are provided. The ear pieces 102 are made of magnets. At the positions on the outer side walls of the left and right square tubes of the transfer frame 1 away from one end of the reset seat 7, telescopic movable holes 103 are provided.

[0039] Among them, on the upper end surface of the support rail 3, a rail groove 301 for the landing gear 10 to slide and snap into is opened. On both sides of the rail groove 301, there are respectively an outer stopper 302 and an inner stopper block 303. The side of the inner stopper block 303 close to it is an inclined surface. At the position of the outer stopper 302 corresponding to the outer hanging plate 3041, an inspection groove 3022 is opened. The outer hanging plate 3041 moves in the inspection groove 3022. The outer end hole edge of the inner jack 3023 is a chamfered structure for facilitating the insertion of the bottom rod of the landing gear 10. The moving space of the stop piece 304 in the outer stopper 302 is the diameter distance of the lock rod 501. When the stop piece 304 is far from the reset seat 7, the lock hole 3043 is misaligned to stop the lock rod 501. When the stop piece 304 is close to the reset seat 7, the lock hole 3043 is aligned with the lock rod 501 to fix the landing gear 10 on the support rail 3. At the middle position of the outer wall of the outer stopper 302 corresponding to the lock frame 5, a slot 3021 is opened, and a crossbar is arranged in the slot 3021.

[0040] Wherein, a lever 4 for pulling, dragging and lifting is connected between the bent portions of the left and right supporting rails 3, and a pull handle 6 for pulling, dragging and lifting is also provided in the middle of the other end of the transfer rack 1.

[0041] Wherein, a tension spring 502 is sleeved on the locking rod 501 outside the outer blocking member 302.

The unlocking rod 503 is rotatably installed in the middle of the lock frame 5. The unlocking rod 503 is made of iron. The lower end of the unlocking rod 503 is a fork structure that can be inserted into the slot 3021. When the lock frame 5 is in the state of waiting to insert the lock, the unlocking rod 503 naturally hangs down. When the lock frame 5 moves inwards and the locking rod 501 is inserted into the fixed landing gear 10, the unlocking rod 503 is adsorbed and fixed in the ear 102. When the lock frame 5 is in the unlocking state to prevent locking, the unlocking rod 503 is horizontally inserted into the slot 3021 to limit the position of the lock frame 5.

[0042] Wherein, a retaining disc 702 is fixedly provided on the guide rod 701 outside the outer blocking member 302. The guide rod 701 outside the retaining disc 702 is sleeved with a first spring 703. The first spring 703 provides a reset thrust for the guide rod 701 always towards the side of the inner jack 3023.

[0043] Further explanation: The design in the first embodiment realizes the rapid loading, unloading and fixing of the drone landing gear 10 through the structures of the transfer rack 1 and the supporting rail 3. The arc-shaped structure of the supporting rail 3 and the design of the reset seat 7 enable the landing gear 10 to easily slide into and be fixed on the supporting rail 3. The settings of the outer blocking member 302 and the inner blocking edge block 303 ensure the stability of the landing gear 10 during transportation. The combined use of the lock frame 5 and the locking rod 501 further enhances the fixing effect of the landing gear 10 and prevents it from moving or falling off during transportation. The design of the reinforcing support rod 101 and the ear 102 improves the overall strength and stability of the transfer rack 1. At the same time, the magnetic design of the ear 102 makes the fixing of the lock frame 5 more convenient. The settings of the lever 4 and the pull handle 6 facilitate the movement and operation of the trailer. The designs of the tension spring 502 and the first spring 703 ensure the automaticity and reliability of the locking rod 501 and the guide rod 701 during the fixing and resetting processes.

[0044] Embodiment 2: Please refer to Figure 8 and Figure 10 , on the basis of the first embodiment, it further includes: a universal wheel 2 with a brake, which is installed at the two corners at one end of the bottom of the transfer rack 1. A telescopic wheel frame 8 that can be telescopic in the transfer rack 1 is provided at the other end of the transfer rack 1. A fixed wheel 801 for walking is provided on the telescopic wheel frame 8. The square tubes at the left and right ends of the telescopic wheel frame 8 are respectively inserted into the square tubes at the left and right ends of the transfer rack 1. A limiting frame 9 for controlling the telescopic movement of the telescopic wheel frame 8 is provided at the end of the transfer rack 1 away from the telescopic wheel frame 8. A dial post 802 is vertically provided at the end position of the telescopic wheel frame 8 corresponding to the telescopic movable hole 103, and the dial post 802 passes through the telescopic movable hole 103.

[0045] Among them, a locking pin 901 is vertically slidably provided on the limit frame 9. The upper end of the locking pin 901 is provided with a finger cap 902 that is wider at the top and narrower at the bottom. The lower end of the locking pin 901 is provided with a limit block 903 along the side wall of the transfer frame 1 downward. The lower end of the limit block 903 is a bevel structure facing the telescopic wheel frame 8 side. The limit block 903 is used to stop the shifting post 802 from moving towards the pull handle 6 side. A second spring 904 is provided on the locking pin 901 above the limit block 903. When the telescopic wheel frame 8 retracts into the transfer frame 1, the limit block 903 is squeezed upward by the shifting post 802. Under the action of the second spring 904, the limit block 903 resets to limit the movement of the shifting post 802. When the telescopic wheel frame 8 needs to be pulled out, the finger lifts the finger cap 902 upward to drag the transfer frame 1, and the telescopic wheel frame 8 is pulled out from the transfer frame 1.

[0046] Further explanation: The design in the second embodiment realizes the flexible movement and fixation of the trailer through the setting of the universal wheels 2 and the telescopic wheel frame 8. The universal wheels 2 have a braking function, ensuring the stability of the trailer when parked. The design of the telescopic wheel frame 8 enables the trailer to retract when not in use, saving space. The combined use of the limit frame 9 and the locking pin 901 ensures the stability and safety of the telescopic wheel frame 8 during the telescopic process. The design of the shifting post 802 and the limit block 903 makes the telescopic operation of the telescopic wheel frame 8 more convenient and reliable. The setting of the second spring 904 ensures the automatic reset function of the limit block 903 during the telescopic process of the telescopic wheel frame 8.

[0047] Embodiment 3: Please refer to Figure 9 、 Figure 11 and Figure 12 On the basis of Embodiment 1, it further includes: a transfer fixing bracket 11. The transfer fixing bracket 11 is used to support and fix the transfer frame 1 for transferring and transporting on the low-altitude equipment transfer platform vehicle. "Return" - shaped side rails 12 are respectively provided on the inner walls of the left and right end side plates of the transfer fixing bracket 11. The side rails 12 are provided with wheel axle strip holes 1201. The left and right two fixed wheels 801 are rotationally connected through a wheel axle. The end of the wheel axle of the fixed wheel 801 protrudes outwards. The end of the wheel axle of the fixed wheel 801 can be interference - slidably clamped in the wheel axle strip hole 1201. An installation and unloading port 1202 through which the wheel axle of the fixed wheel 801 can be taken out from the wheel axle strip hole 1201 is opened at a position of the side rail 12 close to the open end of the transfer fixing bracket 11. A fixing jack 1101 is provided at the center of the bottom plate of the open end of the transfer fixing bracket 11. A fixing pin 13 is vertically slidably provided at a position corresponding to the fixing jack 1101 on the transfer frame 1. The fixing pin 13 is inserted into the fixing jack 1101 to fix the transfer frame 1 on the transfer fixing bracket 11.

[0048] Among them, a hanging rod 1301 is vertically provided at the upper end of the fixing pin 13. A retaining ring 1303 is fixedly provided on the fixing pin 13 below the transfer rack 1. A third spring 1302 is sleeved on the fixing pin 13 between the retaining ring 1303 and the transfer rack 1. A capping 1304 is vertically upward provided on the transfer rack 1 on one side of the fixing pin 13. The upper end of the capping 1304 is a card slot for accommodating the hanging rod 1301. When the hanging rod 1301 is stuck on the capping 1304, the lower end of the fixing pin 13 will not interfere with the transfer fixing support 11.

[0049] Further explanation: The design in Embodiment 3 realizes the fixing and transportation of the transfer rack 1 on the low-altitude equipment transfer platform vehicle through the arrangement of the transfer fixing support 11 and the fixing pin 13. The design of the side rail 12 and the wheel axle strip hole 1201 enables the fixing wheel 801 to be conveniently installed and disassembled. The arrangement of the loading and unloading port 1202 further simplifies the loading and unloading operation of the fixing wheel 801. The combined use of the fixing jack 1101 and the fixing pin 13 ensures the stability and safety of the transfer rack 1 on the transfer fixing support 11. The design of the hanging rod 1301 and the capping 1304 enables the fixing pin 13 to be conveniently retracted when not in use, avoiding interference with the transfer fixing support 11. The arrangement of the third spring 1302 ensures the automatic reset function of the fixing pin 13 during the fixing and retracting processes.

[0050] The core function of Embodiment 1 is to realize the rapid loading, unloading and fixing of the UAV landing gear 10, and its working principle is as follows:

[0051] The landing gear 10 of the drone slides into the rail groove 301 through the arc-shaped structure of the supporting rail 3. The arc-shaped design of the supporting rail 3 reduces the difficulty of loading the landing gear 10, enabling it to slide in easily. The end of the bottom rod of the landing gear 10 is inserted into the inner insertion hole 3023, and preliminary fixation is achieved through the cooperation of the outer stopper 302 and the inner edge block 303. The locking frame 5 firmly fixes the landing gear 10 on the supporting rail 3 by inserting the locking rod 501 into the locking hole 3043 of the stopper 304. The movable design of the stopper 304 enables the locking rod 501 to automatically align with the locking hole 3043 when the landing gear 10 is loaded, ensuring the convenience and reliability of the fixation process, achieving the effect that the landing gear 10 can be automatically fixed and locked when pushed in, which is stable and reliable. And one end of the landing gear 10 is inserted into the inner insertion hole 3023 to avoid the problem of bouncing. The locking frame 5 always maintains a pulling force towards the outer stopper 302 side through the pulling force of the tension spring 502, ensuring that the locking rod 501 can be stably inserted into the locking hole 3043. The design of the unlocking rod 503 further enhances the fixation effect. When it is necessary to maintain the unlocked state, the unlocking rod 503 is horizontally inserted into the slot 3021 to limit the position of the locking frame 5. The locking frame 5 is magnetically adsorbed on the ear 102 to prevent abnormal noise during transportation and avoid the misinsertion of the unlocking rod 503 from affecting the unloading of the landing gear 10.

When it is necessary to pull out the telescopic wheel rack 8, simply lift the finger cap 902 upwards to unlock the limit block 903, and the telescopic wheel rack 8 can be smoothly pulled out. Through the cooperation of the universal wheels 2 and the telescopic wheel rack 8, the trailer can not only move flexibly on flat ground, but also maintain stability through the braking and fixing functions of the telescopic wheel rack 8 when parked. It is suitable for the loading and unloading of the low-altitude equipment transfer platform vehicle in the folded state, avoiding the problem that the low-altitude equipment transfer platform vehicle is still too high and inconvenient for loading and unloading. At the same time, the low-altitude equipment transfer platform adopts a modular design, which can quickly adjust the structure according to the size and weight of different low-altitude equipment, meeting the rapid transfer and loading and unloading requirements of various low-altitude equipment. The low-altitude equipment transfer platform adopts a high-energy density battery system with strong endurance and short charging time. It is equipped with an energy recovery system to recover energy during braking or downhill, and has remote control and autonomous transfer functions. It uses thermal imaging, low-light image acquisition video, millimeter-wave radar, and sensors for automatic operation to realize functions such as automatic route specification, bin docking, aircraft position transfer, safe driving, and obstacle avoidance, which can improve the transfer use scenarios of unmanned aerial vehicles, improve the equipment transfer efficiency, and reduce the risk of manual operation.

[0054] Embodiment 3 adds the fixing function of the transfer rack 1 on the low-altitude equipment transfer platform vehicle on the basis of Embodiment 1 and Embodiment 2, and its working principle is as follows:

[0055] Through the design of the side rail 12 and the wheel axle strip hole 1201 of the transfer fixing bracket 11, the fixed wheel 801 can be conveniently installed and disassembled. The fixing pin 13 fixes the transfer rack 1 on the transfer fixing bracket 11 through the fixing jack 1101, ensuring the transportation stability of the transfer rack 1 on large vehicles. The fixing pin 13 ensures its automatic reset during the fixing and retracting processes through the reset function of the third spring 1302. The design of the hanging rod 1301 and the capping 1304 enables the fixing pin 13 to be conveniently retracted when not in use, avoiding interference with the transfer fixing bracket 11. The loading and unloading port 1202 on the side rail 12 simplifies the loading and unloading operation of the fixed wheel 801, making the installation and disassembly of the transfer rack 1 on the transfer fixing bracket 11 more convenient. The combined use of the fixing pin 13 and the fixing jack 1101 further enhances the stability and safety of the transfer rack 1 during transportation.
