Description

Technical Field

[0001] This utility model belongs to the field of logistics and transportation technology, specifically relating to a cage loading and unloading device and an unmanned vehicle. Background Technology

[0002] With the rapid development of e-commerce, the express delivery industry has also experienced explosive growth in business volume. To improve logistics efficiency, many express delivery companies have introduced automated sorting lines. These automated sorting lines can quickly and accurately sort large numbers of express parcels to different destinations. However, in order to complete the transportation of the parcels, the sorted parcels usually need to be placed in cages and then transported and delivered by unmanned vehicles or other transportation tools.

[0003] Existing cage loading devices mainly employ a tilting structure. While this loading method enables automated loading, it presents numerous problems in practical applications. The tilting loading device requires tilting the cage during operation, which inherently poses safety hazards. During tilting, the cage may become unstable or insecurely secured, easily causing packages inside to tip over, scatter, or even be damaged, thus impacting customer experience and the company's reputation.

[0004] In addition, the mechanical structure of the tipping loading device is complex, requiring more transmission components and control systems. This not only increases the manufacturing and maintenance costs of the equipment, but may also lead to a decrease in loading efficiency due to mechanical failure, affecting the overall operation of the logistics system.

[0005] Therefore, it is necessary to provide a new solution to the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0038] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0039] With the rapid development of e-commerce and the express delivery industry, logistics demands are constantly increasing, and express delivery companies are investing more and more in automated sorting and transportation. In existing technologies, cage loading devices generally adopt a tilting structure, which, while achieving a certain degree of automation, presents several problems in practical applications. These include safety hazards during the tilting process, the risk of package damage, complex mechanical structures, and high manufacturing and maintenance costs. These issues seriously affect the reliability and efficiency of the loading device.

[0040] This invention introduces a lifting and translation mechanism to replace the flipping operation through a lifting mechanism and a translation mechanism, thereby avoiding the flipping operation of the cage, which greatly reduces safety risks and the possibility of package damage. It also simplifies the mechanical structure of the loading device, reduces the complexity of transmission components and control systems, and thus reduces manufacturing and maintenance costs.

[0041] Please refer to Figure 1 and Figure 2 As shown, a cage loading and unloading device 100 in one embodiment of the present invention includes: a support frame 1, a lifting mechanism 2, and a translation mechanism 3. The support frame 1 includes a receiving space 11 for receiving a cage 200, and the rear end of the support frame 1 is provided with an opening 12 for the cage 200 to enter and exit the receiving space 11. The lifting mechanism 2 includes a lifting platform 21 that is movably disposed at the rear end of the support frame 1, and the lifting platform 21 can transport the cage 200 carried thereon to the opening 12. The translation mechanism 3 includes a translation bracket 31 disposed on the support frame 1, and the translation bracket 31 can move along the front-back direction of the receiving space 11. The translation bracket 31 is provided with a limiting component 32, which includes a first state and a second state. In the first state, the limiting component 32 can interfere with the cage 200 in the front-back direction, and in the second state, the limiting component 32 can release the interference with the cage 200 in the front-back direction.

[0042] Please refer to Figure 1 and Figure 4 As shown, the support frame 1 provides the basic structural support for the entire device, ensuring that other components can operate stably and efficiently. The design of the receiving space 11 ensures the containment and protection of the cage 200 during loading and unloading, while the opening 12 provides a passage for the cage 200 to enter and exit. The support frame 1 can be made of high-strength metal material to ensure sufficient load-bearing capacity and durability. The size and structural design of the support frame 1 should be able to accommodate cages 200 of different specifications, ensuring that the cages 200 can smoothly enter and exit the receiving space 11. A guide device can be installed at the opening 12 of the receiving space 11 to assist the cages 200 in entering and exiting, improving the convenience and safety of operation. The size of the receiving space 11 can be designed according to needs; for example, the receiving space 11 can be designed to have a large volume to accommodate multiple cages 200.

[0043] Please refer to Figure 1 and Figure 5As shown, the lifting mechanism 2 adjusts the height of the cage 200 by vertically moving the lifting platform 21, and works in conjunction with the translation mechanism 3 to load and unload the cage 200. The design of the lifting platform 21 allows the cage 200 to smoothly enter and exit the support frame 1, avoiding the safety risks associated with tipping operations. The lifting platform 21 can be implemented using hydraulic cylinders, electric push rods, or screw lifting technologies, and its lifting speed and height should be adjustable to adapt to different operational needs. An anti-slip pad can be provided on the surface of the lifting platform 21 to ensure the stability of the cage 200 during lifting. The lifting mechanism 2 can be equipped with safety devices, such as limit switches and emergency stop buttons, to ensure operational safety.

[0044] Please refer to Figure 1 and Figure 6 As shown, the translation mechanism 3 adjusts the cage 200 in the horizontal position (front-back direction) by moving the translation bracket 31 back and forth. The limiting component 32 interferes with the cage 200 in the first state to ensure that the cage 200 does not detach from the bracket during translation; in the second state, the interference is released, facilitating the loading and unloading of the cage 200. The translation bracket 31 can use a track sliding or roller sliding method to achieve smooth front-back movement. The translation bracket 31 can be driven by a motor, gear transmission, or belt transmission to ensure the accuracy and reliability of the translation operation. The limiting component 32 can be designed as an adjustable structure to accommodate cages 200 of different sizes.

[0045] In one exemplary embodiment, please refer to Figure 1 and Figure 6 As shown, the translation mechanism 3 also includes a translation slide rail 33 extending in the front-back direction of the receiving space 11. The translation slide rail 33 is fixedly connected to the support frame 1, and the translation bracket 31 is slidably connected to the translation slide rail 33. The translation bracket 31 can slide back and forth along the translation slide rail 33 so that the translation bracket 31 can extend beyond the rear end of the support frame 1.

[0046] The translation slide rail 33 is the foundation of the translation mechanism 3, extending along the front-rear direction of the receiving space 11 and fixedly connected to the support frame 1. The design of the slide rail must ensure sufficient strength and stability to support the movement of the translation bracket 31 during loading and unloading. The limiting component 32 can dock with the cage 200 on the lifting platform 21 when the translation bracket 31 extends beyond the rear end of the support frame 1, forming interference to ensure the stability of the cage 200 during loading and unloading.

[0047] For details, please refer to Figure 3 and Figure 6As shown, the limiting component 32 includes a limiting member 321, a transmission shaft 322, and a rotation drive member 323. The transmission shaft 322 is rotatably mounted on the translation bracket 31. The rotation drive member 323 is connected to the transmission shaft 322 to drive the transmission shaft 322 to rotate. The limiting member 321 is located at the rear end of the translation bracket 31 and one end is connected to the transmission shaft 322. Rotating the transmission shaft 322 can switch the state of the limiting member 321.

[0048] The limiting component 321 is the part that directly contacts the cage 200 and forms interference. It can be designed as a stop or other form to accommodate cages 200 of different sizes and shapes. The material of the limiting component 321 can be a wear-resistant, high-strength material, such as stainless steel or high-strength plastic. The drive shaft 322 is the transmission component of the limiting assembly 32 and is rotatably mounted on the translation bracket 31. The design of the drive shaft 322 should ensure its rotational flexibility and load-bearing capacity. It can be a solid or hollow metal shaft and undergo appropriate heat treatment and surface treatment to improve durability. The rotary drive component 323 is responsible for driving the drive shaft 322 to rotate and can be an electric motor, pneumatic motor, or manual knob, etc.

[0049] The rotation of the drive shaft 322 is controlled by the rotary drive 323. By rotating the drive shaft 322, the limiting member 321 can switch between a first state (interference state) and a second state (non-interference state). The rotary drive 323 provides rotational power to the drive shaft 322. By controlling the start and stop of the rotary drive 323, the state switching of the limiting member 321 can be precisely controlled. For example, when it is necessary to drag the cage 200, the limiting member 321 interferes with the cage 200; while when it is necessary to release the cage 200, the limiting member 321 releases the interference from the cage 200.

[0050] Furthermore, the other end of the limiting member 321 is located on the roller 324. In the first state, the rotation axis of the roller 324 is parallel to the left and right direction of the support frame 1. The limiting member 321 is designed to reliably contact the cage 200, ensuring that it can effectively interfere with the movement of the cage 200 in the first state, while not hindering the free loading and unloading of the cage 200 in the second state.

[0051] The roller 324 can be made of a low-friction material, such as polyurethane or nylon. These materials are not only wear-resistant but also significantly reduce the friction between the roller 324 and the cage 200. The rotation axis of the roller 324 is parallel to the left-right direction of the support frame 1. This design ensures that the roller 324 can roll smoothly when in contact with the cage 200 during the lifting and lowering process, reducing the friction between the limiting member 321 and the cage 200.

[0052] In one exemplary embodiment, please refer to Figure 6As shown, the translation support 31 includes a first support 311 and a second support 312 respectively disposed on the left and right sides of the receiving space 11. The rear ends of the first support 311 and the second support 312 are provided with guide blocks 313 that are inclined towards the outer sides of the left and right sides of the receiving space 11.

[0053] The first support 311 and the second support 312 are respectively located on the left and right sides of the receiving space 11, together forming the main structure of the translation support 31. The translation support 31, through the combination of the first support 311 and the second support 312, achieves smooth movement of the cage 200. The guide block 313 is installed at the rear end of the first support 311 and the second support 312, guiding the cage 200 into the receiving space 11. The inclined design allows the cage 200 to automatically adjust its position when entering the receiving space 11, avoiding impact or jamming, and improving the smoothness and safety of the loading and unloading process.

[0054] In one exemplary embodiment, please refer to Figure 1 and Figure 5 As shown, the lifting mechanism 2 also includes a lifting guide rail 22, a connecting member 23, and a lifting electric cylinder 24. The lifting guide rail 22 is fixedly connected to the rear end of the support frame 1. One end of the connecting member 23 is slidably connected to the lifting guide rail 22, and the other end is fixedly connected to the lifting platform 21. The lifting electric cylinder 24 is fixed on the lifting guide rail 22, and the telescopic rod of the lifting electric cylinder 24 is connected to the connecting member 23 to drive the connecting member 23 to move up and down along the lifting guide rail 22.

[0055] The lifting guide rail 22 provides a guide path for the vertical movement of the connecting piece 23, ensuring that the connecting piece 23 remains stable and precise during lifting. The connecting piece 23, through a sliding connection with the guide rail, achieves stable lifting of the lifting platform 21. One end of the connecting piece 23 is fixedly connected to the lifting platform 21; its vertical movement drives the lifting platform 21 to rise and fall together, achieving height adjustment of the cage 200. The telescopic rod of the lifting electric cylinder 24 is connected to the connecting piece 23, providing the power required for lifting. The drive system of the electric cylinder, by controlling the extension and retraction of the telescopic rod, achieves precise control of the connecting piece 23, ensuring the stability and safety of the lifting process.

[0056] Specifically, the lifting platform 21 has first guide baffles 25 on both its left and right sides, with the rear ends of the first guide baffles 25 inclined outwards towards the lifting platform 21. The lifting platform 21 provides a stable support platform for the cage 200, and its vertical movement enables the cage 200 to be raised and lowered. The outward inclined design of the rear ends of the first guide baffles 25 allows them to guide the cage 200 as it enters the lifting platform 21, preventing the cage 200 from deviating or getting stuck. The inclined baffles can automatically adjust the position of the cage 200, ensuring its accurate entry into the lifting platform 21.

[0057] Furthermore, the lifting platform 21 includes a central support plate 211 and side support plates 212 located on the left and right sides of the central support plate 211 respectively. The side support plates 212 are arranged to correspond to the moving wheels of the cage 200, and the length of the side support plates 212 is less than the length of the central support plate 211. The rear ends of both the central support plate 211 and the side support plates 212 are arranged in a sloping shape.

[0058] The central support plate 211 is a core component of the lifting platform 21, providing the main load-bearing surface. Its length and strength design must meet the size and weight requirements of the cage 200 to ensure stability during lifting. Side support plates 212 are located on the left and right sides of the central support plate 211, corresponding to the casters of the cage 200. The side support plates 212 are designed to be shorter than the central support plate 211; this design helps reduce the movement path of the cage 200's casters on the lifting platform 21, thereby improving loading and unloading efficiency. The rear ends of both the central support plate 211 and the side support plates 212 are designed as ramps. This design facilitates pushing the cage 200 into the lifting platform 21, reducing the force required for pushing and also reducing wear on the cage 200 and the lifting platform 21.

[0059] In one exemplary embodiment, a first position sensor 26 for detecting the position of the cage 200 is provided on the lifting platform 21. When the cage 200 reaches a predetermined position on the lifting platform 21, the first position sensor 26 is triggered, generating a sensing signal. This sensing signal provides feedback on the position of the cage 200, indicating that the cage 200 is in place and subsequent lifting operations can be safely performed. The sensing signal output by the sensor can be input into the control system, and the control system performs corresponding operations based on the signal, such as activating the lifting cylinder 24 for lifting, ensuring the automation and accuracy of the entire operation process.

[0060] The first position sensor 26 can be a photoelectric sensor, proximity sensor, or ultrasonic sensor, etc., and the most suitable sensor type should be selected according to the actual working environment and accuracy requirements. The sensor should be installed in an appropriate position on the lifting platform 21 to ensure that it can accurately detect the arrival of the cage 200. The installation position needs to be determined according to the size of the cage 200 and the layout of the lifting platform 21.

[0061] In one exemplary embodiment, please refer to Figure 1 and Figure 4 As shown, the support frame 1 includes a base plate 13 and support frames 14 disposed on the left and right sides of the base plate 13. A second guide baffle 15 is provided on the base plate 13. The second guide baffle 15 is located on the left and right sides of the receiving space 11, and the rear end of the second guide baffle 15 is inclined to the outside of the receiving space 11.

[0062] The support frame 1 serves as the foundation structure of the entire loading and unloading system, bearing the stability and guidance of the entire lifting and translating mechanism 3. The base plate 13 is the core part of the support frame 1, and it must ensure sufficient rigidity and load-bearing capacity to support the weight of components such as the lifting platform 21 and the translating support 31, as well as the forces generated during operation.

[0063] Support frames 14 are located on the left and right sides of the base plate 13, forming a stable frame structure. The support frames 14 are connected to the base plate 13 by bolts or welding to ensure that they will not loosen or shift during use. Second guide baffles 15 are located on the base plate 13, on the left and right sides of the receiving space 11. The second guide baffles 15 help guide the cage 200 to maintain the correct orientation when entering the receiving space 11, preventing lateral displacement of the cage 200 during loading and unloading.

[0064] Specifically, the second guide baffle 15 is equipped with a second position sensor 16 for detecting the position of the cage 200. The second sensor detects the position of the cage 200 to ensure accurate triggering when the cage 200 reaches the predetermined position. The signal output by the second sensor alerts the operator or control system that the cage 200 is in position and the pushing and pulling operation of the translation mechanism 3 can be stopped. For example, after the second position sensor 16 is triggered, it generates a sensing signal, which is transmitted to the control system. After receiving the signal, the control system recognizes that the cage 200 has been loaded into position and issues a command to stop the pushing and pulling action of the translation mechanism 3.

[0065] In one exemplary embodiment, please refer to Figure 1 and Figure 7 As shown, the support frame 14 is provided with a locking assembly 4 for locking the cage 200. The locking assembly 4 includes a fixed base 41, a locking block 42, a return spring 43, a locking rope 44, a locking rope fixing end 45, and a locking wheel 46. The fixed base 41 is fixed to the support frame 14, and the locking block 42 is movably connected to the fixed base 41. The locking block 42 is provided with a pin 47, which passes through the fixed base 41. The return spring 43 is sleeved on the pin 47, and its two ends abut against the fixed base 41 and the end of the pin 47, respectively. The return spring 43 is used to provide the elastic force to drive the locking block 42 away from the cage 200 housed in the receiving space 11. One end of the locking rope 44 is fixedly connected to the locking rope fixed end 45, and the other end passes through the end of the pin 47 and is wound around the locking wheel 46. The locking wheel 46 is rotatably connected to the fixed base 41. Rotating the locking wheel 46 in a predetermined direction can cause the locking rope 44 to drive the pin 47 to compress the return spring 43, so that the locking block 42 abuts against the cage 200 housed in the housing space 11.

[0066] The mounting base 41 can be made of high-strength metal materials, such as steel or aluminum alloy, to ensure its strength and durability when securing the locking assembly 4. The mounting base 41 can be securely mounted on the support frame 14, while providing room for movement for the locking block 42 and the pin 47. The locking block 42 is designed with stability and safety in contact with the cage 200 in mind, and its shape should conform to the shape of the cage 200 to ensure that it can firmly hold the cage 200 when locked.

[0067] The locking assembly 4 achieves stable locking of the cage 200 through the tight cooperation of the fixed base 41, locking block 42, return spring 43, locking rope 44, and locking wheel 46. The fixed base 41 provides basic support, the locking block 42 is movably connected by the pin 47, the return spring 43 provides return elasticity, and the locking rope 44 and locking wheel 46 achieve the clamping and releasing of the locking block 42 by rotation.

[0068] Specifically, the support frame 14 is provided with a rotatable limiting block 17. Rotating the limiting block 17 allows it to be locked onto the cage 200 housed within the receiving space 11. The limiting block 17 is designed to make firm contact with the cage 200 and may include grooves or protrusions to increase the holding force.

[0069] The edges of the limiting block 17 can be rounded to avoid damage to the cage 200. The rotating mechanism can be designed for manual or automatic operation. Manual operation can be achieved via a handle or knob, while automatic operation can be controlled by an electric motor or pneumatic device. The limiting block 17 is connected to the support frame 14 via a rotating shaft or pivot, and can rotate smoothly under the action of the rotating mechanism. When the limiting block 17 rotates to a certain position, it can firmly contact and hold the cage 200, preventing the cage 200 from moving within the receiving space 11.

[0070] For details, please refer to Figure 4 As shown, the front end of the support frame 1 is fitted with a limiting baffle 18, and a controller is located on the front side of the limiting baffle 18. The limiting baffle 18, installed at the front end of the support frame 1, provides physical limiting and positioning functions for the cage 200, restricting the position of the cage 200 within the receiving space 11 and preventing the cage 200 from moving forward or sliding out during loading, unloading, or transportation. The controller, installed on the front side of the limiting baffle 18, provides control functions for the entire device. The limiting baffle 18 provides a stable mounting platform for the controller. The controller can communicate and control other parts of the device (such as sensors, lifting mechanism 2, translation mechanism 3, etc.) via signal lines or wireless connections, ensuring the coordination and efficiency of the entire operation process.

[0071] Please refer to Figure 8As shown, one embodiment of this utility model also provides an unmanned vehicle 300, which includes the aforementioned cage loading and unloading device 100. Specifically, the cage loading and unloading device 100 is installed inside the vehicle compartment of the unmanned vehicle 300, and the cage 200 can be loaded into the vehicle compartment through the cage loading and unloading device 100.

[0072] In summary, the cage loading and unloading device and unmanned vehicle provided by this utility model can realize the vertical movement of the cage through the lifting operation of the lifting platform, so that the cage can cooperate with the translation mechanism to complete the horizontal movement without flipping the cage, thereby avoiding the safety hazards and damage to the package during the flipping process. The design of the lifting mechanism and the translation mechanism makes the mechanical structure of the loading device simpler, reduces the complexity of the transmission components and control system, thereby reducing manufacturing and maintenance costs.
