Description

Technical Field

[0001] The utility model relates to the technical field of UAV transportation, and particularly relates to a fixing device for a large UAV. Background Art

[0002] Under the background of the rapid growth of the national economy, UAV technology has been deeply applied in many fields, including traditional agriculture and forestry, industrial production, disaster emergency response, public safety guarantee, and the consumer market, etc. Especially for those areas that are difficult for humans to reach, such as high mountains or remote areas, the task of transporting heavy equipment or materials often relies on large UAVs to complete.

[0003] However, in the traditional UAV transportation mode, due to its small size and light weight, the common fixing method is to use a strap or simply place the UAV in a box for transportation. When this fixing method is applied to large UAVs, however, many challenges are faced. The increase in the size and weight of the large body makes it difficult for the traditional fixing method to ensure stability, and the UAV's skids and body are likely to be damaged due to shaking during transportation, thus affecting its flight performance and safety. Summary of the Utility Model

[0004] Aiming at the above defects, the technical problem to be solved by the utility model is to provide a fixing device for a large UAV, which can improve the fixing stability of the large UAV during transportation and reduce the risk of damage to the large UAV during transportation.

[0005] The above technical purpose of the utility model is achieved by the following technical solutions:

[0006] A fixing device for a large UAV includes a fixing member arranged on a transport vehicle. A chute is formed in the fixing member, and two sliding members are slidably connected in the chute. One of the sliding members is fixedly connected with a stud, and a nut is threadedly connected to the stud. A connecting member is fixedly connected to the other sliding member. One end of the connecting member away from the sliding member is hinged with a clamping seat. A connecting portion is provided at one end of the clamping seat away from the connecting member. The nut abuts against the connecting portion in the direction towards the fixing member. A clamping portion is provided in the middle section of the clamping seat, and the clamping portion is used to jointly clamp the skid of the UAV with the fixing member.

[0007] By adopting the above scheme, when in use, the nut is separated from the stud, and the holder is rotated around the hinge with the connector, so that the free end of the holder is away from the stud. The sled of the drone is placed on the fixing member and is located between the stud and the connector. The holder is rotated around the hinge with the connector, so that the free end of the holder is close to the stud, and the nut is installed on the stud, and the connecting part is supported by the nut toward the fixing part, so that the clamping part and the fixing part clamp the sled of the drone together. The sled of the drone is fixed to the transport vehicle by a fixing device, which effectively improves the stability of the drone during transportation. Since both sliding parts can slide in the slide groove, the stud and the connector can move a certain distance along the length direction of the slide groove, so as to adapt to different specifications of the sled of the drone, and can also adapt to the sled that has been deformed due to external force.

[0008] The utility model is further configured that the clamping part is an arc-shaped part that matches the slide of the drone. The arc-shaped clamping part is more consistent with the shape of the slide of the drone, thereby improving the stability of the clamping part clamping the slide.

[0009] The utility model is further configured that the connecting portion is in a U-shaped fork shape, and a section of the stud is located inside the connecting portion. Since the connecting portion is in a U-shaped fork shape, the separation and connection between the connecting portion and the stud are easier and faster.

[0010] The utility model is further configured such that both side walls of the slide groove distributed in the width direction are provided with limit grooves in the longitudinal direction, and the end of the sliding member corresponding to the limit groove is provided with a first limit portion, and the first limit portion extends into the limit groove on the corresponding side. Since the first limit portion is located in the slide groove, it is difficult for the sliding member to escape from the slide groove upwards, thereby ensuring the fixing effect of the card holder on the slide of the drone.

[0011] The present utility model is further configured such that the first limiting portion is located at the lower section of the sliding member, the upper section of the sliding member has a second limiting portion, the projection of the second limiting portion on the fixing member is square, the widths of both the first limiting portion and the second limiting portion match the width of the sliding groove, the second limiting portion is slidably connected in the sliding groove, and the width of the limiting groove allows the second limiting portion and the corresponding first limiting portion on one side to be inserted simultaneously. During the assembly process, align the widths of the first limiting portion and the second limiting portion with the width of the sliding groove, insert the sliding member into the sliding groove. After the bottom of the sliding member contacts the bottom of the sliding groove, rotate the sliding member so that the first limiting portion enters the corresponding limiting groove. During the rotation of the sliding member, the four corner portions of the square-shaped second limiting portion can enter the limiting groove, preventing the second limiting portion from being stuck by the sliding groove. When fixing the skid of the unmanned aerial vehicle, lift the sliding member upward, and the second limiting portion enters the inner side of the mouth of the sliding groove. Since the projection of the second limiting portion on the fixing member is square, the second limiting portion cooperates with the sliding groove to prevent the sliding member from rotating, thereby preventing the part connected to the sliding member from rotating. When installing or disassembling a nut on the stud, the sliding member can limit the rotation of the stud.

[0012] The present utility model is further configured such that the free end of the first limiting portion is arc-shaped. Since the free end of the first limiting portion is arc-shaped, the sliding member can avoid the bottom of the limiting groove when rotating in the sliding groove, thereby ensuring that the length of the first limiting portion can match the depth of the limiting groove to the maximum extent.

[0013] The present utility model is further configured such that the fixing member is a rectangular plate.

[0014] The present utility model is further configured such that the fixing member is connected to the transport vehicle by bolts.

[0015] In summary, a large unmanned aerial vehicle fixing device provided by the present utility model has at least the following beneficial effects:

[0016] 1. The stability of the large unmanned aerial vehicle during transportation is improved.

[0017] 2. It can adapt to skids of different specifications of the unmanned aerial vehicle, and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following combines the attached Figures 1-7 drawings and specific embodiments to further elaborate on the present utility model in detail.

[0028] Please refer to Figures 1-7, A fixing device for a large unmanned aerial vehicle provided in this embodiment includes a fixing member 1 provided on a transport vehicle 13. The fixing member 1 can be specifically connected to the transport vehicle 13 by bolts, and the shape of the fixing member 1 is a rectangular plate. A chute 2 is opened on the fixing member 1, and the length direction of the chute 2 is arranged along the left-right direction. Two sliding members 3 are slidably connected in the chute 2, and the two sliding members 3 have a spacing along the length direction of the chute 2. A stud 4 is fixedly connected to the top of the sliding member 3 on the left side, and a nut 5 is threadedly connected to the stud 4. A connecting member 6 is fixedly connected to the top of the sliding member 3 on the right side, and a clamping seat 7 is hinged to one end of the connecting member 6 away from the sliding member 3. A connecting portion 8 is provided at one end of the clamping seat 7 away from the connecting member 6, and the nut 5 abuts against the connecting portion 8 in the direction towards the fixing member 1. A clamping portion 9 is provided in the middle section of the clamping seat 7, and the clamping portion 9 is used to jointly clamp the skid 14 of the unmanned aerial vehicle with the fixing member 1. Specifically, the upper end of the connecting member 6 is hinged to the right end of the clamping seat 7, and the connecting portion 8 is provided at the left end of the clamping seat 7. The connecting portion 8 is preferably in a U-shaped fork shape, and a section of the stud 4 is located inside the connecting portion 8, that is, inside the U-shaped fork. Please refer to Figure 2 , during the use process, when the connecting portion 8 rotates towards the stud 4 around the hinge with the connecting member 6, the stud 4 can enter the inside of the U-shaped fork-shaped connecting portion 8 from the mouth at the left end of the connecting portion 8.

[0029] Please continue to refer to Figure 2 , in order to improve the stability of the nut 5 abutting against the connecting portion 8, a flat washer 16 and a spring washer 15 can also be provided between the connecting portion 8 and the nut 5, and both the flat washer 16 and the spring washer 15 are sleeved on the stud 4.

[0030] Please refer to Figure 2 , the clamping seat 7 is located above the fixing member 1. Preferably, the clamping portion 9 is an arc matching the skid 14 of the unmanned aerial vehicle.

[0031] Please refer to Figures 1-3 , both side walls of the chute 2 distributed along the width direction of the chute 2 are provided with limiting grooves 10 along the longitudinal direction of the chute 2. The corresponding ends of the sliding member 3 are provided with first limiting portions 11, and the first limiting portions 11 extend into the corresponding limiting grooves 10. The free ends of the first limiting portions 11 are arcs. Specifically, please refer to Figures 3-5 , two first limiting portions 11 are provided on the sliding member 3, and the two first limiting portions 11 correspond to the two limiting grooves 10 one by one. The first limiting portions 11 are located at the lower section of the sliding member 3, and the upper section of the sliding member 3 has second limiting portions 12. The projection of the second limiting portions 12 on the fixing member 1 is a square. The widths of both the first limiting portions 11 and the second limiting portions 12 match the width of the chute 2, and the widths of the first limiting portions 11 and the second limiting portions 12 are the same. The second limiting portions 12 are slidably connected in the chute 2, and the width of the limiting grooves 10 allows the second limiting portions 12 and the corresponding first limiting portions 11 on the side to be inserted simultaneously.

[0032] By adopting the above solution, during use, first separate the nut 5 from the stud 4, and rotate the card seat 7 around the hinge joint with the connecting member 6, so that the free end of the card seat 7 moves away from the stud 4. Then, place the skid 14 of the drone on the fixing member 1 and between the stud 4 and the connecting member 6. Rotate the card seat 7 around the hinge joint with the connecting member 6, so that the free end of the card seat 7 approaches the stud 4, install the nut 5 on the stud 4, and push the connecting portion 8 against the fixing member 1 in the direction of the fixing member 1 through the nut 5, so that the clamping portion 9 and the fixing member 1 jointly clamp the skid 14 of the drone. Fixing the skid 14 of the drone on the transport vehicle 13 through the fixing device effectively improves the stability of the drone during transportation. Since both sliding members 3 can slide in the chute 2, the stud 4 and the connecting member 6 can move a certain distance along the length direction of the chute 2, so as to adapt to different specifications of the skid 14 of the drone, and can also adapt to the skid 14 deformed due to external forces.

[0033] During the assembly process, align the widths of the first limiting portion 11 and the second limiting portion 12 with the width of the chute 2, insert the sliding member 3 into the chute 2, and after the bottom of the sliding member 3 contacts the bottom of the chute 2 (at this time, the position of the sliding member 3 refers to Figure 2 ), rotate the sliding member 3 so that the first limiting portion 11 enters the corresponding limiting groove 10. During the rotation of the sliding member 3, since the four corner portions of the second limiting portion 12 which is square can enter the limiting groove 10, the second limiting portion 12 is prevented from being stuck by the chute 2. When fixing the skid 14 of the drone, lift the sliding member 3 upward, and the second limiting portion 12 enters the inner side of the mouth of the chute 2 (at this time, the position of the sliding member 3 refers to Figure 6 ). Since the projection of the second limiting portion 12 on the fixing member 1 is square, the second limiting portion 12 cooperates with the chute 2 to prevent the sliding member 3 from rotating, thereby preventing the part connected to the sliding member 3 from rotating. When installing or disassembling the nut 5 on the stud 4, the sliding member 3 can limit the rotation of the stud 4. When fixing the drone, at least two fixing devices are provided for each skid 14 of the drone, so as to firmly fix the drone on the transport vehicle 13.
