DETAILED DESCRIPTION

[0045] In order to make the technical problems solved in the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0048] In modern logistics and daily life, intelligent hooks, as a convenient tool integrating advanced technology, are gradually showing their great potential in improving efficiency and user experience. Among them, intelligent hooks with automatic unhooking function, by virtue of their intelligent operation mode such as sensor recognition, wireless remote control or preset program control to realize automatic release and locking of goods, greatly simplify the cumbersome process of manual unhooking of traditional hooks, and improve the operation safety and efficiency. For example, if the intelligent hook is installed on a drone for lifting goods, the intelligent hook can be remotely controlled to open to release the goods. However, many automatic unhooking intelligent hook products on the current market integrate complex mechanical structures, control circuits and energy supply systems (such as battery packs), which leads to the fact that the existing intelligent hooks are often bulky, and users usually need to hold the hook with both hands when hanging the goods on the hook, which is difficult to operate and has poor user experience.

[0049] To overcome the above technical problems, with reference to Figures 1-8 The embodiment provides a hook device, which comprises a hand-held long handle 1, a hook 3 and a driving mechanism 2, the hand-held long handle 1 has an installation cavity 14 inside; the hook 3 is rotatably connected to one end of the hand-held long handle 1; the driving mechanism 2 is installed in the installation cavity 14, the hook 3 is in transmission connection with the driving mechanism 2, and the hook 3 is driven to rotate by the driving mechanism 2 to realize the automatic unhooking function.

[0050] Among them, the hand-held long handle 1 is an elongated handle structure, which is convenient for a user to hold with one hand. Preferably, the width of any position of the cross section of the hand-held long handle 1 is not more than 3 cm, so as to facilitate holding.

[0051] Based on the hook device of the embodiment, the hook 3 is connected to one end of the hand-held long handle 1, and the driving mechanism 2 is installed inside the hand-held long handle 1, so that the driving mechanism 2 can drive the hook 3 to rotate to realize the automatic unhooking function. In the scheme, the shell for installing the hook 3 and the driving mechanism 2 is arranged as a slender hand-held long handle 1, so that the user can directly hold the hand-held long handle 1 with one hand when hanging the goods on the hook 3. In this process, the other hand of the user can fix the lifting rope of the goods, thereby simplifying the operation process of the user when hanging the goods, and optimizing the operation experience of the user.

[0052] In an embodiment, the installation cavity 14 is in the shape of a narrow space, and the length direction of the installation cavity 14 is the same as the length direction of the hand-held long handle 1.

[0053] The long and narrow installation cavity 14 can make more efficient use of the space inside the hand-held long handle 1, so that the driving mechanism 2 can be reasonably arranged in a limited space, avoiding the problem of component stacking or unreasonable layout due to insufficient space. In addition, the long and narrow installation cavity 14 also facilitates heat dissipation and subsequent maintenance, which helps to prolong the service life of the internal electronic components, and at the same time, when maintenance or replacement of components is needed, it is also easier to disassemble and install.

[0054] In an embodiment, the driving mechanism 2 includes a battery 21 and a power assembly 22, the battery 21 is electrically connected with the power assembly 22, and the power assembly 22 is in transmission connection with the hook 3.

[0055] The battery 21 as the main energy supply source of the driving mechanism 2 can continuously provide stable power for the power assembly 22, ensuring that the hook device can quickly and reliably complete the automatic unhooking action when needed. Among them, the drive of the power assembly 22 can be but not limited to motor 222, elastic telescopic electromagnet and the like structure, as long as it can drive the hook 3 to rotate through power.

[0056] In an embodiment, referring to Figure 3 , the battery 21 and the power assembly 22 are arranged in the length direction of the hand-held long handle 1 in the installation cavity 14.

[0057] Arranging the battery 21 and the power assembly 22 in the length direction of the hand-held long handle 1 can maximize the use of the longitudinal space of the installation cavity 14, avoiding the waste of space caused by transverse arrangement. This layout makes the entire hook device maintain a compact volume while accommodating more components or larger battery 21 capacity, thus meeting longer use requirements. In addition, arranging the components in the length direction is beneficial to the natural dissipation of heat. Since the battery 21 and the power assembly 22 will generate a certain amount of heat during work, this layout can make the heat gradually release along the long handle direction, reducing the risk of heat accumulation and prolonging the service life of the components.

[0058] In an embodiment, the power assembly 22 is arranged at one end of the installation cavity 14 close to the hook 3, and the battery 21 is arranged at the other end of the installation cavity 14 away from the hook 3.

[0059] As the power assembly 22 and the battery 21 are respectively located at two ends of the installation cavity 14, such a layout helps to optimize the compactness of the entire device, avoids space waste caused by mutual stacking or misplacement of components, and enables the entire hook device to accommodate sufficient power assembly 22 and battery 21 capacity while maintaining a small volume. The layout of the power assembly 22 close to the hook 3 makes the power transmission path more direct and short, which reduces the loss of power during transmission, improves transmission efficiency, and enables the hook 3 to respond to control instructions more quickly and accurately to complete the rotating action.

[0060] In an embodiment, referring to Figure 5 , the hand-held long handle 1 is internally provided with a transverse partition plate 111, which divides the installation cavity 14 into a first installation area 141 and a second installation area 142, and the battery 21 is installed in the first installation area 141, and the power assembly 22 is installed in the second installation area 142.

[0061] The transverse partition plate 111 makes the space in the installation cavity 14 clear, and the first installation area 141 and the second installation area 142 each undertake different functions, respectively for installing the battery 21 and the power assembly 22, avoiding mutual interference between components, and improving the neatness and orderliness of the entire device.

[0062] In an embodiment, the power assembly 22 includes a motor 222, a control board 221, and a transmission unit 223, the output shaft of the motor 222 is drivingly connected to the input end of the transmission unit 223, and the output end of the transmission unit 223 is drivingly connected to the hook 3.

[0063] The motor 222 serves as a power source, directly drives the transmission unit 223 through its output shaft, and further drives the hook 3 to rotate. The transmission unit 223 can output the rotational motion output by the motor 222 as appropriate driving force to drive the hook 3 to rotate, to meet the function of stable unhooking. The control board 221 serves as the brain of the entire power assembly 22, and is responsible for receiving external instructions and controlling the operation of the motor 222. Through electrical connection with the motor 222, the control board 221 can realize accurate control of parameters such as the rotation speed and direction of the motor 222, to meet the needs of the hook 3 in different application scenarios.

[0064] When the device is applied to hoist goods by a UAV, the control board 221 is optionally integrated with a wireless communication module, so that the control board 221 can establish wireless communication with the UAV, and the UAV can send an unhooking instruction to the control board 221 when needed, so that the control board 221 can drive the motor 222 to operate to complete the automatic unhooking action. Specifically, the device can be automatically unhooked when the goods are hoisted to the destination, or the device can be automatically unhooked when the UAV is trapped by an obstacle (such as a tree or a power pole) during flight, thereby realizing the function of autonomous escape of the UAV.

[0065] In an embodiment, in combination with Figure 6 The control board 221 and the battery 21 are distributed along the length direction of the long handle 1 in the mounting cavity 14, and the control board 221 is close to the first side wall of the mounting cavity 14, and the motor 222 and the transmission unit 223 are arranged on the side of the control board 221 away from the first side wall.

[0066] The first side wall can be a front side wall, a rear side wall, a left side wall, or a right side wall in the mounting cavity 14. By arranging the control board 221 close to the first side wall of the mounting cavity 14, and arranging the motor 222 and the transmission unit 223 on the side of the control board 221 away from the first side wall, the space in the mounting cavity 14 can be more effectively utilized. This front-rear (or left-right) arrangement helps to further reduce the width and height of the device, thereby improving its compactness.

[0067] In addition, the design of the control board 221 close to the first side wall of the mounting cavity 14 helps to naturally dissipate heat. Since the control board 221 generates a certain amount of heat during operation, the first side wall can act as a heat dissipation channel to help conduct heat out of the device, thereby improving the heat dissipation performance.

[0068] In an embodiment, in combination with Figure 5 The transmission unit 223 includes a first transmission group 2231 and a second transmission group 2332, the first transmission group 2231 is connected to the hook 3, and the second transmission group 2332 is connected to the motor 222; the first transmission group 2231 is provided with a first elastic return member 22312, and the motor 222 can drive the second transmission group 2332 to switch between a first position and a second position; in the first position, the second transmission group 2332 locks the first transmission group 2231, so that the hook 3 remains in a hookable state; in the second position, the first transmission group 2231 is unlocked, and the first elastic return member 22312 drives the hook 3 to rotate to realize automatic unhooking.

[0069] In the normal state, the motor 222 is stationary, the second transmission group 2332 is in the first position, and the second transmission group 2332 is locked by the first transmission group 2231. When the hook is unhooked, the motor 222 operates to drive the second transmission group 2332 to switch to the second position, at which time the second transmission group 2332 loses the locking force of the first transmission group 2231, and the first elastic return member 22312 releases the elastic potential energy to drive the hook 3 to rotate to achieve unhooking. In order to realize the locking function of the second transmission group 2332 to the first transmission group 2231, a locking structure (such as a structure that can be buckled with each other) that can cooperate with each other needs to be arranged between the second transmission group 2332 and the first transmission group 2231. When the second transmission group 2332 is in the first position, the locking structure is locked in cooperation, and when the second transmission group 2332 is in the second position, the locking structure is unlocked.

[0070] The elastic force of the first elastic return member 22312 is used to drive the hook 3 to rotate to achieve the automatic unhooking function. Therefore, as long as the first transmission group 2231 can be locked in the unhooked state to make the first elastic return member 22312 unable to release the elastic potential energy, and the first transmission group 2231 is unlocked when unhooking is needed, so that the first elastic return member 22312 can freely release the elastic potential energy. The second transmission group 2332 is used to control the locking and unlocking of the first transmission group 2231. At this time, the first transmission group 2231 only needs to be able to switch between the first position and the second position. Obviously, this structure has a simple operation mode and is easy to implement, and is beneficial to the stability of the transmission group. When unlocking, the elastic force of the first elastic return member 22312 is used to drive the hook 3 to rotate. The first elastic return member 22312 has stable elastic force output, so it can ensure that the hook 3 can quickly and accurately complete the unhooking action when needed, and will not cause the problem of unhooking failure due to external interference or mechanical wear.

[0071] In the first embodiment, the first elastic return member 22312 needs to be able to provide a torque to drive the hook 3 to rotate, and preferably, the first elastic return member 22312 is a torsional spring or a clockwork.

[0072] In an embodiment, the first transmission group 2231 further comprises a cam 22311, the cam 22311 is fixedly connected with the hook 3 and the rotation centers of the two coincide, and the first elastic return member 22312 is connected with the cam 22311. When the second transmission group 2332 is in the first position, the second transmission group 2332 locks the rotation of the cam 22311, and the first elastic return member 22312 is in an energy storage state.

[0073] The cam 22311 is fixedly connected with the hook 3, and a protruding structure formed on one side of the cam 22311 can be accurately matched with the second transmission group 2332 to form a locking mechanism, which ensures that the hook 3 can be stably kept in position in the hooked state and cannot be accidentally unhitched due to external interference. The first elastic reset member 22312 is connected to the cam 22311, and when the second transmission group 2332 is in the first position, it locks the rotation of the cam 22311, and the hook 3 is also kept fixed. At this time, the first elastic reset member 22312 is in an energy storage state, and stores energy for subsequent unhitching action. When unhitching is needed, the second transmission group 2332 is switched to the second position to release the locking of the cam 22311. At this time, the first elastic reset member 22312 rapidly releases the stored energy to drive the cam 22311 (and the hook 3 fixedly connected thereto) to rotate, thereby realizing automatic unhitching.

[0074] The cam 22311 of the first transmission group 2231 in this scheme can be frequently matched and locked with the second transmission group 2332, and at the same time, the first elastic reset member 22312 can drive the hook 3 to rotate through the cam 22311 when unlocking. This structure has the advantages of simplicity and good stability.

[0075] Optionally, in combination with Figure 7 A placing groove capable of accommodating the first elastic reset member 22312 is formed on one side of the cam 22311, the first elastic reset member 22312 is installed in the placing groove, one end of the first elastic reset member 22312 is fixedly connected to the cam 22311, and the other end is fixed to the hand-held long handle 1, thereby realizing the driving of the cam 22311 by the first elastic reset member 22312. This structure also has the advantage of compactness.

[0076] In an embodiment, referring to Figure 5 The hand-held long handle 1 is provided with two parallel connection clamping plates 161 at one end for connecting the hook 3, and the hook 3 is arranged between the two connection clamping plates 161. The mounting cavity 14 includes a third mounting area 143 extending into the connection clamping plates 161, the cam 22311 is installed in the third mounting area 143, and the cam 22311 is connected with a rotating shaft 22313 extending out of the third mounting area 143, and the hook 3 is fixedly connected to the rotating shaft 22313.

[0077] At one end of the hand-held long handle 1 for connecting the hook 3, two parallel connection clamping plates 161 are provided, which provide a stable frame for supporting and fixing the hook 3. The hook 3 is arranged between the two connection clamping plates 161, which ensures that the hook 3 has sufficient stability during operation and is not easy to deviate or be damaged due to external force.

[0078] The third mounting area 143 is arranged in the connecting plate 161, and the cam 22311 is arranged in the third mounting area 143, which facilitates the direct connection of the rotating shaft 22313 to the cam 22311 and the hook 3, and facilitates the function that the rotation of the hook 3 is directly driven by the cam 22311. This structure makes full use of the internal space of the hand-held long handle 1, and has the advantages of good compactness and good reliability.

[0079] In one embodiment, referring to Figure 7 , one of the third mounting areas 143 is arranged in each of the two connecting plates 161, the cam 22311 is arranged in one of the third mounting areas 143, and at least a part of the control plate 221 extends into the other third mounting area 143.

[0080] That is, one third mounting area 143 is arranged in each of the two connecting plates 161, one of the third mounting areas 143 is used to arrange the cam 22311, and the other third mounting area 143 is used to accommodate a part of the control plate 221, which facilitates making full use of the internal space of the hand-held long handle 1, arranging the flat control plate 221 in it, improving the compactness of the structure, and thus facilitating the reduction of the size of the entire hand-held long handle 1.

[0081] In one embodiment, referring to Figure 4 , the first transmission group 2231 and the second transmission group 2332 are arranged in the mounting cavity 14 along the length direction of the hand-held long handle 1.

[0082] Arranging the first transmission group 2231 and the second transmission group 2332 along the length direction of the hand-held long handle 1 facilitates the installation of the two groups in the long and narrow mounting cavity 14, and facilitates the function that the first transmission group 2231 and the second transmission group 2332 can stably cooperate with each other.

[0083] In one embodiment, the connecting plate is provided with an axle hole through which the rotating shaft 22313 passes, and the rotating shaft 22313 is provided with a shaft sealing ring 17, and the shaft sealing ring 17 tightly contacts the side wall of the connecting plate 161 provided with the axle hole.

[0084] Specifically, the cam 22311 is arranged inside the connecting plate 161, and the hook 3 is arranged outside the connecting plate 161, so that an axle hole is arranged on one side of the connecting plate 161 to allow the rotating shaft 22313 to pass through during assembly, so that the two ends of the rotating shaft 22313 can be connected to the cam 22311 and the hook 3 inside and outside, respectively. However, in order to make the hook 3 rotate smoothly, a gap needs to be reserved between the rotating shaft 22313 and the axle hole, and the gap will have the risk of water entering. Referring to Figure 7The rotating shaft 22313 is sleeved with the sealing ring, and the clamping plate 161 can fill the gap between the rotating shaft 22313 and the shaft hole, so that the shaft hole is effectively sealed, and the waterproof capability of the hook device is ensured.

[0085] In an embodiment, the connecting clamping plate 161 is further provided with a shaft sealing groove coaxial with the shaft hole, and the shaft sealing ring 17 is embedded in the shaft sealing groove and tightly contacts the connecting clamping plate 161.

[0086] The shaft sealing groove is arranged on the connecting clamping plate 161, so that the shaft sealing ring 17 can be embedded in the shaft sealing groove, which effectively improves the reliability of the connection between the shaft sealing ring 17 and the connecting clamping plate 161, increases the contact area between the two, and improves the waterproof capability.

[0087] In an embodiment, referring to Figures 4-5 The second transmission group 2332 includes a second elastic return member 23323, and the second elastic return member 23323 drives the second transmission group 2332 to remain in the first position by its elastic force.

[0088] The second transmission group 2332 is an important component group in the device, which can include connecting rods, gears, chains, belts or other transmission elements for transmitting power or motion. The second transmission group 2332 has a specific function, that is, to control the locking and unlocking of the cam 22311. The second elastic return member 23323 (such as a spring) is a component that can store and release elastic force. In this embodiment, the second elastic return member 23323 drives the second transmission group 2332 to remain in the first position by its elastic force, which means that when there is no external force, the second transmission group 2332 will remain in the position of locking the cam 22311 due to the elastic force of the second elastic return member 23323. When it is necessary to unlock the cam 22311, the second transmission group 2332 can be driven by the motor 222 to overcome the elastic force of the second elastic return member 23323, so that the second transmission group 2332 moves to the second position. Once the second transmission group 2332 moves to the second position, the cam 22311 is no longer locked and can freely rotate or move.

[0089] This scheme realizes a device with automatic locking and unlocking function by introducing the second elastic return member 23323. When the external force disappears, the second elastic return member 23323 will automatically push the second transmission group 2332 back to the first position, thereby locking the cam 22311. This design not only improves the reliability and safety of the device, but also makes the operation more convenient and fast.

[0090] In an embodiment, referring to Figure 5The second transmission assembly 2332 includes a lever 23321, a transmission connecting rod 23322, and a locking rod 23324. The lever 23321 and the locking rod 23324 are arranged within the mounting cavity 14 along the length of the handgrip handle 1. One end of the lever 23321 is connected to the motor 222, and the other end is movably connected to the transmission connecting rod 23322. One end of the locking rod 23324 is rotatably connected to the handgrip handle 1, and the other end is movably connected to the motor 222. The transmission link 23322; under the elastic force of the second elastic reset member 23323, the locking rod 23324 is in the first position, and the locking rod 23324 locks the first transmission group 2231; the motor 222 can push the transmission link 23322 to the second position through the lever 23321, and the transmission link 23322 synchronously drives the locking rod 23324 to the second position, and the first transmission group 2231 is unlocked.

[0091] In specific work, Figure 5 For example, under normal conditions, the locking rod 23324 keeps the locking cam 22311 locked by the elastic force of the second elastic reset member 23323. When it is necessary to disengage, the motor 222 drives the lever 23321 to swing upward. The lever 23321 overcomes the elastic force of the second elastic reset member 23323 and pushes the transmission link 23322 to move upward. The transmission link 23322 drives the locking rod 23324 to swing upward. After the locking rod 23324 swings upward, it disengages from the locking of the cam 22311. Under the elastic force of the first elastic reset member 22312, it drives the cam 22311 to rotate. The cam 22311 then drives the hook 3 to rotate to achieve disengagement.

[0092] The second transmission group 2332 includes a lever 23321, a transmission link 23322, and a locking lever 23324. These components work together to lock and unlock the first transmission group 2231. The lever 23321 and the locking lever 23324 are arranged in the mounting cavity 14 along the length of the handle 1. Power is transmitted between them through the transmission link 23322. This allows them to fit the narrow structure within the mounting cavity 14, enabling the accurate transmission of the driving force of the motor 222 to the rotation of the drive hook 3 within the narrow space.

[0093] In one embodiment, the transmission link 23322 is slidably installed inside the handle 1 along its length. The second elastic reset member 23323 is sleeved on the transmission link 23322. Under the elastic force of the second elastic reset member 23323, the transmission link 23322 is in a first position, thereby locking the locking rod 23324 in the first position.

[0094] The transmission connecting rod 23322 is slidably installed along the length direction of the long handle 1, which can achieve the purpose of transmitting the movement of the shifting rod 23321 to the locking rod 23324. This structure has the advantages of compactness and good stability.

[0095] In an embodiment, the middle part of the transmission connecting rod 23322 is provided with a long hole that can slide in the direction of the long hole itself, and the shifting rod 23321 extends into the long hole to achieve the active connection with the transmission connecting rod 23322.

[0096] The transmission connecting rod 23322 is provided with a long hole to connect with the shifting rod 23321, which can achieve the purpose of pushing the transmission connecting rod 23322 to slide linearly by the swinging movement of the shifting rod 23321.

[0097] In an embodiment, in combination Figures 2-3 , the long handle 1 comprises a middle frame 11 and first and second side cover plates 12 and 13 respectively installed on both sides of the middle frame 11.

[0098] The middle frame 11 is the main supporting structure of the long handle 1, which provides sufficient strength and rigidity to ensure the stability and durability of the device during use.

The first and second side cover plates 12 and 13 are respectively installed on both sides of the middle frame 11, which not only provides additional support and protection, but also beautifies the appearance of the device. The first and second side cover plates 12 and 13 can be fixedly connected with the middle frame 11 by screws, buckles or other means. Optionally, the first or second side cover plate 12 or 13 also contains some hole positions or openings for heat dissipation, operation or observation.

[0099] By combining the middle frame 11, the first side cover plate 12 and the second side cover plate 13 together, a long handle 1 with compact structure and high strength is formed, which not only improves the stability and durability of the device, but also makes the device more beautiful and easy to operate.

[0100] In an embodiment, in combination Figure 7 , the two sides of the middle frame 11 are respectively provided with a sealing ring 18 arranged around the installation cavity 14, and the first and second side cover plates 12 and 13 respectively tightly contact the two sealing rings 18 from both sides.

[0101] Specifically, sealing rings 18 are respectively arranged between the first side cover plate 12 and the middle frame 11, and between the second side cover plate 13 and the middle frame 11, and the sealing rings 18 are arranged around the installation cavity 14, which can effectively fill the joint gaps of the first side cover plate 12, the middle frame 11 and the second side cover plate 13, and then realize reliable sealing of the internal installation cavity 14, thereby improving the safety of the hook device.

[0102] In an embodiment, the two ends of the hand-held long handle 1 are respectively a hoisting end 15 and a hooking end 16, the hook 3 is connected to the hooking end 16, and the hoisting end 15 is provided with a lifting hole 151.

[0103] The two ends of the hand-held long handle 1 are designed as different functional areas, which are respectively a hoisting end 15 and a hooking end 16. The hoisting end 15 is usually located at the upper end of the hand-held long handle 1 and is used to connect with hoisting equipment (such as a drone, a crane, a hook, etc.) so as to hoist or move the entire device. The hooking end 16 is located at the other end of the hand-held long handle 1 and is used to connect the hook 3 or other objects that need to be hung. The hoisting end 15 is provided with a lifting hole 151, which is a key connection point and is used to connect with the hook or rope of the hoisting equipment.

[0104] In an embodiment, the hook 3 includes a hook groove, and one end of the hand-held long handle 1 is further provided with a detaching piece 4, which can close the slot of the hook groove and can be rotated to open the slot to the inside of the hook groove.

[0105] Based on the setting of the detaching piece 4, when the goods are hung, the detaching piece 4 can be pushed to rotate inwardly to open, so that the lifting rope of the goods can be hung in the hook groove.
