Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone accessories technology, specifically a hook with remote control cargo release function. Background Technology
[0002] With the rapid development of drone technology, its application in low-altitude lifting operations is becoming more and more widespread. The market has put forward higher requirements for the performance of the matching hooks. They not only need to meet the basic load-bearing requirements of lifting operations, but also need to take into account operational safety, lightweight structure and operation efficiency.
[0003] However, existing hooks have poor locking performance. When the cargo is overweight or encounters turbulence during flight, the locking structure of the hook is prone to loosening, causing the cargo to fall unexpectedly, resulting in damage to materials or injury to personnel on the ground. Secondly, they lack remote control functions. Most hooks require operators to be close to the lifting area and manually release the cargo. In scenarios such as working at heights or in hazardous environments, operators close to the work area are directly exposed to personal safety threats such as falls from heights, exposure to hazardous environments, and electric shock. In addition, some existing hooks have complex mechanical structures designed to achieve basic locking functions, which not only increases manufacturing costs and assembly difficulty, but also makes operation cumbersome. Operators need to spend a lot of time adjusting the locking state, reducing the efficiency of lifting operations.
[0004] To address this issue, we designed a hook with remote control for releasing cargo. Utility Model Content
[0005] The purpose of this invention is to provide a hook with remote control for releasing cargo, in order to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a hook with remote control cargo release function, comprising: two side guard plates, which are detachably connected by bolts to form a mounting cavity; a locking buckle, rotatably disposed inside the mounting cavity, whose opening and closing state is used to lock or release cargo; a push rod assembly, including a push rod motor and a linear push rod, the push rod motor being fixedly installed in the mounting cavity formed by the two side guard plates, one end of the linear push rod being drivenly connected to the output end of the push rod motor, and the other end being hinged to the rotating end of the locking buckle; and a lower hook, corresponding to the locking buckle, fixed to the bottom of the side guard plate, used to cooperate with the locking buckle to carry cargo.
[0007] Furthermore, it also includes a remote control module, which is installed in the mounting cavity and electrically connected to the push rod motor. The remote control module is used to receive external remote control signals and drive the push rod motor to rotate forward and backward according to the signals, so as to control the extension or retraction of the linear push rod, thereby driving the locking buckle to close to lock the goods.
[0008] Furthermore, a hanging ring is attached to the top of the side guard plate for connection to the drone.
[0009] Furthermore, the side guard plate, locking buckle, lower hook and linear push rod are all made of high-strength alloy.
[0010] Furthermore, the height of the side guard plate is adapted to the height of the push rod motor.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The linear push rod driven by the push rod motor closes the locking buckle and the lower hook to form a locking structure. Even if the cargo is overweight or the drone encounters turbulent air, it can prevent the buckle from loosening and causing the cargo to fall. The push rod motor drives the forward and reverse rotation to lock and release the cargo, avoiding the risk of falling from heights when working in high-altitude or dangerous environments. Moreover, there is no need to manually adjust the complex locking device, which shortens the operation time. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3This utility model provides a technical solution: a hook with remote control for releasing cargo, comprising two side guard plates 1, which are detachably connected by bolts to form an installation cavity; a locking buckle 3, which is rotatably disposed inside the installation cavity, and whose opening and closing state is used to lock or release cargo; a push rod assembly, including a push rod motor 2 and a linear push rod, wherein the push rod motor 2 is fixedly installed in the installation cavity formed by the two side guard plates 1, one end of the linear push rod is connected to the output end of the push rod motor 2, and the other end is hinged to the rotating end of the locking buckle 3; and a lower hook 4, which is correspondingly disposed to the locking buckle 3 and fixed to the bottom of the side guard plate 1, for cooperating with the locking buckle 3 to carry cargo.
[0016] In practical implementation, when it is necessary to clamp the cargo, the push rod motor 2 drives the linear push rod to extend, pushing the locking buckle 3 to rotate downward around its rotation axis, so that it tightly closes with the lower hook 4, forming a complete and closed load-bearing ring, thereby firmly locking the cargo. When it is necessary to release the cargo, the push rod motor 2 drives the linear push rod to retract, pulling the locking buckle 3 to rotate upward, separating it from the lower hook 4, and the cargo can then automatically fall off under the action of gravity. In this setting, even if the cargo is overweight or the drone encounters strong air currents and violent turbulence, the locking structure composed of the push rod motor 2 and the linear push rod can keep the position of the locking buckle 3 from shifting, effectively preventing the cargo from falling accidentally, improving operational safety. Moreover, when using this device, the operator does not need to manually adjust the complex locking device; they only need to control the push rod motor 2 to complete the locking or releasing instantly, shortening the operation time and improving the lifting efficiency.
[0017] See Figure 1-3 It also includes a remote control module, which is installed in the mounting cavity and electrically connected to the push rod motor 2. The remote control module is used to receive external remote control signals and drive the push rod motor 2 to rotate forward and backward according to the signals, so as to control the linear push rod to extend or retract, thereby driving the locking buckle 3 to close to lock the goods.
[0018] It should be noted that the control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
[0019] In practice, the operator sends a wireless signal to the remote control module on the hook through a ground remote controller or the flight control system of the drone. After receiving the signal, the remote control module decodes and processes it, and then sends a corresponding electrical signal to the push rod motor 2 to control its forward or reverse rotation, thereby realizing the remote release of the cargo.
[0020] See Figure 1-3The top of the side guard plate 1 is connected to a hanging ring 5 for connecting to the drone.
[0021] In practice, the lifting ring 5 can be easily and quickly connected and disconnected from the landing gear or mounting points of most drones on the market, improving product compatibility.
[0022] See Figure 1-3 The side guard plate 1, locking buckle 3, lower hook 4 and linear push rod are all made of high-strength alloy.
[0023] In practice, the high-strength alloy has fatigue resistance and corrosion resistance, enabling it to work stably for a long time in outdoor environments, which further extends the service life of the device.
[0024] See Figure 1-3 The height of the side guard plate 1 is adapted to the height of the push rod motor 2.
[0025] In practice, this design completely encloses the push rod motor 2 inside the side guard plate 1, which can better protect the push rod motor 2 from external collisions and severe weather.
[0026] Working principle: The lifting device for the goods to be lifted is placed on the lower hook 4, which is fixed to the bottom of the side guard plate 1. A signal is sent through the remote control module. After receiving the signal, the remote control module decodes and processes it, driving the push rod motor 2 to rotate forward. The push rod motor 2 drives the linear push rod to extend. The other end of the linear push rod is hinged to the rotating end of the locking buckle 3. Under the action of the push rod, the locking buckle 3 rotates downward around its rotation axis until it is tightly closed with the lower hook 4, locking the goods. Once the goods arrive at the designated delivery location, the operator sends a signal to the remote control module. The remote control module then drives the push rod motor 2 to reverse, causing the linear push rod to retract. The linear push rod pulls the rotating end of the locking buckle 3 upward, causing the locking buckle 3 to separate from the lower hook 4.
