Description

Technical Field

[0001] This utility model relates to the field of drone technology, and in particular to a delivery clamping device for drones. Background Technology

[0002] In recent years, with the development of e-commerce, the transportation and delivery of goods has developed rapidly. Manual delivery of goods is time-consuming and costly, and when goods are piled up, they cannot be delivered to customers in a timely and efficient manner. The introduction of drone technology has greatly improved the efficiency of goods delivery. When transporting express packages by drone, express clamping devices are used.

[0003] A search revealed a Chinese patent publication number CN216684866U, which discloses a package clamping device for drones. The device includes a mounting base with two vertically downward clamping plates that slide along its length on the lower end face of the mounting base. The two clamping plates are positioned opposite each other and spaced apart. The mounting base is equipped with a drive device for driving the two clamping plates to move synchronously and in opposite directions. This patent, by incorporating a movable plate and an inner bend, effectively prevents the package from falling when it slides down.

[0004] However, its movable plate relies on gravity to hang down naturally to support the package. If the drone experiences significant acceleration or turbulence during flight, the movable plate may shake unexpectedly, making the support unreliable. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: A package clamping device for drones, such as Figures 1 to 4 As shown, the device includes a fixed frame 1, with side clamps 2 slidably connected to the two ends of the bottom of the fixed frame 1. A movable plate 3 is provided at the bottom of the side clamps 2. A rotating shaft 5 is fixedly connected to the side wall of the movable plate 3. The outer wall of the rotating shaft 5 is rotatably connected to the side clamps 2. A cavity 6 is opened in the side wall of the side clamps 2. A torsion spring 7 is sleeved at one end of the rotating shaft 5 and located inside the cavity 6. The two ends of the torsion spring 7 are fixedly connected to the rotating shaft 5 and the inner wall of the cavity 6, respectively. Support plates 4 are fixedly connected to the opposite side of the bottom of the two movable plates 3. The distance between the adjacent ends of the two support plates 4 is less than the distance between the two side clamps 2.

[0027] The side plate 2 has a guide groove 9 on its side wall. The inner wall of the guide groove 9 is vertically slidably connected to the same pressure plate 10. The bottom outer wall of the fixed frame 1 is fixedly connected to both ends of the guide rod 11. The pressure plate 10 and the outer wall of the guide rod 11 are slidably engaged. The outer wall of the guide rod 11 is provided with a spring. The two ends of the spring are respectively connected to the outer walls of the fixed frame 1 and the pressure plate 10.

[0028] Two side clamps 2 are connected to each other on their opposite outer walls by a connecting assembly 13 with clamping blocks 12. The clamping blocks 12 are rectangular or arc-shaped. The connecting assembly 13 includes a connecting block 17 and a fixing rod 16. The connecting block 17 is connected to the side wall of the side clamp 2. The fixing rod 16 is slidably connected to the inner wall of the connecting block 17. A magnetic strip 18 is fixedly connected to the side wall of the fixing rod 16. A magnetic strip 29 is fixedly connected to the inner wall of the connecting block 17. The magnetic strip 18 and the magnetic strip 29 are magnetically attracted to each other.

[0029] The mounting bracket 1 is fixedly connected to the bottom of the drone. Before transporting the package, the package with the corresponding external shape is selected according to the shape of the clamping block 12 under the drone. The drone carries the device above the package and then descends. The movable plate 3 first contacts the ground or table surface. The movable plate 3 rotates outward about the rotating shaft 5 as the rotation center. The rotating shaft 5 drives the torsion spring 7 to twist and store force. The pressure plate 10 is pushed upward along the guide rod 11 by the package. The spring is compressed and stored force. Then the drive assembly 8 drives the side clamping plates 2 to move towards each other. The clamping block 12 clamps the package, and the pressure plate 10 presses the package from above. The limit is set, and then the drone moves upward. The torsion spring 7 causes the rotating shaft 5 to rotate, the movable plate 3 is reset, and the support plate 4 is located below the express delivery. The different shapes of the clamping blocks 12 can ensure the contact area between the clamping blocks 12 and the express delivery, ensuring stable clamping of the express delivery. When installing the clamping blocks 12, the fixing rod 16 is inserted into the connecting block 17, and the magnetic strip 18 and magnetic strip 2 19 are magnetically fixed. The clamping blocks 12 can be easily replaced by magnetic strip 18 and magnetic strip 2 19. When there are many express delivery packages of one shape, the device with clamping blocks 12 of another shape installed can be replaced with the corresponding clamping blocks 12.

[0030] By incorporating a pivot 5, a cavity 6, and a torsion spring 7, the support plate 4 can always remain below the moving plate 3 when it is not compressed, preventing accidental shaking and ensuring reliable support.

[0031] By setting up the connecting component 13 and the clamping block 12, the contact area between the clamping block 12 and the express delivery can be guaranteed by using different shapes of the clamping block 12, ensuring stable clamping of the express delivery, and the clamping block 12 can be easily replaced.

[0032] Example 2: A package clamping device for drones. This example is based on Example 1 and makes the following improvements, such as... Figure 4 As shown, the side plate 2 has a connecting cavity 14 on its side wall. The connecting block 17 is slidably connected to the inner wall of the connecting cavity 14. A pressure sensor 15 is installed on the inner wall of the connecting cavity 14. The detection end of the pressure sensor 15 is in contact with the side wall of the connecting block 17. The pressure sensor 15 and the drive assembly 8 are both electrically connected to the controller. The controller is a mature existing technology, so it will not be described in detail here.

[0033] When clamping the express delivery, after the clamping block 12 comes into contact with the express delivery, the reaction force of the clamping block 12 pressing on the outer wall of the express delivery is transmitted to the pressure sensor 15 through the connecting block 17. When the force detected by the pressure sensor 15 reaches the preset value, the drive component 8 stops driving the side clamping plate 2 to move, so as to avoid the clamping block 12 applying too much clamping force to the outer wall of the express delivery, causing damage or deformation to the outer wall of the express delivery.

[0034] By providing a connecting cavity 14 and a pressure sensor 15, the clamping force of the clamping block 12 on the express can be controlled, avoiding excessive clamping force applied by the clamping block 12 to the outer wall of the express, which could cause damage or deformation to the outer wall of the express.

[0035] Working principle: The mounting bracket 1 is fixedly connected to the bottom of the drone. Before transporting the package, the package with the corresponding external shape is selected according to the shape of the clamping block 12 under the drone. Then, the drone carries the device above the package and descends. The movable plate 3 first contacts the ground or table surface. The movable plate 3 rotates outward about the rotating shaft 5 as the rotation center. The rotating shaft 5 drives the torsion spring 7 to twist and store force. The pressure plate 10 is pushed upward along the guide rod 11 by the package. The spring is compressed and stores force. Then, the drive assembly 8 drives the side clamping plates 2 to move towards each other. The clamping block 12 clamps the package. When the clamping block 12 contacts the package, the reaction force of the clamping block 12 pressing on the outer wall of the package is transmitted to the pressure sensor 15 through the connecting block 17. When the force detected by the pressure sensor 15 reaches the preset value, the drive assembly 8 drives the side clamping plates 2 to move towards each other. The clamping block 12 clamps the package. When the clamping block 12 contacts the package, the reaction force of the clamping block 12 pressing on the outer wall of the package is transmitted to the pressure sensor 15 through the connecting block 17. When the force detected by the pressure sensor 15 reaches the preset value, the drive assembly 8 is activated. When component 8 stops moving the side clamping plate 2, it prevents the clamping block 12 from applying excessive clamping force to the outer wall of the express delivery, which could cause damage or deformation to the outer wall of the express delivery. The pressure plate 10 presses and limits the express delivery from above, and then the drone moves upward. The torsion spring 7 causes the rotating shaft 5 to rotate, the movable plate 3 resets, and the support plate 4 is located below the express delivery. Different shapes of the clamping block 12 can ensure the contact area between the clamping block 12 and the express delivery, ensuring stable clamping of the express delivery. When installing the clamping block 12, the fixing rod 16 is inserted into the connecting block 17, and the magnetic strip 18 and magnetic strip 2 19 are magnetically fixed. The clamping block 12 can be easily replaced by magnetic strip 18 and magnetic strip 2 19. When there are many express delivery packages of one shape, the device with clamping block 12 of another shape can be replaced with the corresponding clamping block 12.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
