Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of transfer distribution trolley, especially to the folding cigarette distribution trolley of liftable. BACKGROUND

[0002] In the logistics distribution process of the tobacco industry, cigarettes are usually packaged and transported in the form of turnover boxes. These turnover boxes not only need to be transferred between warehouses, but also need to be unloaded from distribution vehicles to retail points or further sorting centers. The traditional manual handling method is inefficient, labor-intensive, and prone to damage to goods, especially in the case of frequent loading and unloading. In addition, due to the particularity of cigarette products, both protection from external environment and safety and integrity during handling are required, thus higher requirements are put forward for handling tools.

[0003] The existing trolley design mostly does not have lifting function, resulting in inconvenience in transfer between different height platforms, increasing the difficulty of workers loading and unloading goods. For example, when transferring cigarettes from a higher position (such as a truck compartment) to a lower position (such as the ground or a store shelf), workers have to take laborious manual loading and unloading methods or use additional auxiliary equipment, which not only reduces work efficiency, but also may increase the risk of injury.

[0004] Therefore, the folding cigarette distribution trolley of liftable is proposed to solve the above problems. SUMMARY

[0005] To solve the above problems, the utility model provides a folding cigarette distribution trolley of liftable, which is particularly suitable for transfer requirements in the tobacco industry. The trolley realizes height adjustment and automatic movement of the flat car by combining the design of the scissor-shaped lifting frame and the electric drive system, greatly reducing the burden of manual operation. Specifically, it includes a lifting module, a flat car, a control module, and an electric box. The lifting module adopts a scissor-shaped lifting frame design to lift the goods on the flat car for easy transfer. The bottom of the lifting module is provided with a chassis, and the top is connected with the bottom of the flat car. The control module is electrically connected with the electric box and the electric cylinder of the lifting module.

[0006] Further description of the foregoing scheme, one end of the bottom of the flat car is provided with a steering wheel, which can adopt a universal wheel, and the other end is provided with a drive wheel. The motor inside the drive wheel is electrically connected with the control module to realize electric drive.

[0007] Further, to prevent goods from falling, the top of the flat car is provided with folding telescopic guardrails, which are rotatably connected with the flat car through hinges. The adjacent folding telescopic guardrails are fixed through locks, and the folding telescopic guardrails can be folded, unfolded, and telescoped according to actual conditions.

[0008] Further to the foregoing, the electric box is fixed at the end of the flat car, and the electric box internally comprises a battery and an electric control module, and the surface of the electric box is further provided with an emergency switch, a display screen and a lifting switch; the electric control module is electrically connected with the battery, the emergency switch, the display screen and the lifting switch; the electric control module integrates a power management system, a controller, a driving circuit and a protection circuit.

[0009] Optionally, handles are arranged at the two ends of the electric box, so as to facilitate the control of the forward and backward sliding of the flat car when the flat car is lifted up.

[0010] Further to the foregoing, the control module is installed above one end of the flat car through a fixing rod, handles are arranged at the two ends of the control module, and a handle is further sleeved with a steering handle at the other end, so as to control the rotation of the driving wheel through the steering handle; and a key for switching forward and backward movement is further arranged on the control module.

[0011] More preferably, a roller shutter module is installed on the fixing rod, and the roller shutter module accommodates a roller shutter cloth, which is used for shielding goods on the flat car.

[0012] Optionally, the bottom frame is provided with a roller, so as to facilitate the overall movement when the flat car is lifted up.

[0013] Compared with the prior art, the utility model discloses a shear-shaped lifting frame design and the height adjustment function of the flat car, which can easily match the loading and unloading platforms of different heights, such as truck compartments and warehouse shelves. The cigarette turnover box can be directly slid onto the trolley or unloaded from the trolley, greatly reducing the number and intensity of manual handling and improving the overall efficiency of loading and unloading operations.

[0014] The electric drive system enables the trolley to easily slide on the horizontal plane, and can be flexibly operated even in a narrow space without the need for manual pushing. This feature not only saves physical effort, but also reduces the risk of occupational injuries caused by repetitive labor, improves the comfort and safety of work.

[0015] The folding telescopic guardrails arranged on the top of the flat car can be flexibly adjusted in size according to the loading condition, and are fixed through a lock buckle, effectively preventing accidental falling of goods during transportation. The roller shutter module further provides shielding protection for the goods, especially for the transportation of fragile or valuable goods.

[0016] The utility model effectively reduces the overall cost of logistics distribution. At the same time, the fast and efficient loading and unloading process also indirectly promotes the smooth operation of the supply chain, bringing significant economic benefits to enterprises.

[0017] In summary, the liftable and foldable cigarette distribution cart not only solves many problems existing in the traditional cart in the tobacco transfer process, but also realizes performance improvement and innovation breakthrough in many aspects, and provides a more efficient, safe, economic and environment-friendly solution for the logistics distribution of the tobacco industry.

DETAILED DESCRIPTION

[0028] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0029] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0030] Please refer to Figures 1-6 The present embodiment includes a lifting module 1, a flat car 2, a control module 5 and an electrical box 6. The lifting module 1 is designed with a scissor-shaped lifting frame 12 for lifting goods on the flat car 2, facilitating transfer. The bottom of the lifting module 1 is provided with a chassis 11, and the bottom of the flat car 2 and the inside of the chassis 11 are both provided with a roller frame 14. The top is connected to the bottom of the flat car 2. The control module 5 is electrically connected to the electric cylinder 13 of the lifting module 1 and the electrical box 6. One end of the bottom of the flat car 2 is provided with a steering wheel 21, which can be a universal wheel. The other end is provided with a drive wheel 22. The motor inside the drive wheel 22 is electrically connected to the control module 5, realizing electric drive. In the present embodiment, the steering wheel 21 is designed with a universal wheel, which allows the wheel to rotate freely in any direction, making the flat car flexible to turn in a narrow space. The universal wheel is composed of a fixed bracket and a freely rotating axle, with two small wheels perpendicular and intersecting installed on the axle. When force is applied, the two small wheels will simultaneously contact the ground and rotate with the object moving, realizing omnidirectional movement. For application scenarios that require more stable steering performance, universal wheels with locking function can also be considered, which are fixed in one direction when not needed. It should be noted that the present embodiment uses 4 wheels, and 3 wheels can also be used, just like ordinary forklifts, which use single-wheel steering.

[0031] In the prior art, the drive wheel 22 can use a brushless direct current motor (BLDC) or a stepper motor as a power source. These motors have the characteristics of high efficiency and low noise, and can provide sufficient torque to drive the flat car to move. The drive wheel 22 is usually equipped with a reducer to obtain appropriate speed and torque output, ensuring smooth operation of the vehicle under different load conditions. In addition, the drive wheel 22 also includes feedback devices such as encoders for monitoring the position and speed of the wheel, thereby realizing precise speed control and positioning.

[0032] The control module 5 is the core of the entire system, which is responsible for receiving the operator's instructions and controlling the working state of other components through electrical signals. The control module 5 is built based on a microcontroller unit (MCU), which has a built-in CPU and other peripheral interfaces, and can achieve complex logic operations and real-time control through programming. In some embodiments, in addition to managing the electric cylinder 13 of the lifting module 1, the control module 5 also needs to coordinate the operation of the motor inside the drive wheel 22, and monitor various parameters of the system such as voltage, current, etc. In this embodiment, in order to improve the user experience, the control module 5 is equipped with a button 52 for switching forward / backward mode, and a handle 51 for adjusting the speed, so that the user can intuitively operate the device.

[0033] The scissor lift 12 is a common mechanical structure widely used in various devices that require vertical lifting, such as aerial work platforms, cargo loading platforms, etc. It is composed of multiple sets of intersecting connecting rods, which are connected together through hinges to form one or more "X" shaped frames. When the lifting action occurs, these connecting rods will expand or contract like scissors, thereby realizing the rising and falling of the platform. The connecting rod is the main part of the scissor structure, usually made of high-strength steel to ensure sufficient carrying capacity and durability. The guide column is to ensure the stability and straightness during lifting, and the scissor lift is usually equipped with a guide column or guide rail system. These components restrict the lateral movement of the connecting rods, so that the entire structure can only move in the vertical direction. The bottom of the scissor lift in this embodiment is fixed on the chassis 11, and the top is connected with the flat car 2. The base provides a stable foundation, while the top plate is responsible for supporting and transmitting the load from above.

[0034] Power transmission is accomplished through the electric cylinder 13. The electric cylinder converts electrical energy into mechanical motion, pushing the expansion or contraction of the scissor structure. Specifically: the electric cylinder contains a lead screw and a matching nut inside. When the motor rotates, it drives the lead screw to rotate, and the nut moves axially along the lead screw, thereby pushing or pulling one end of the scissor structure. The electric cylinder uses a motor as the power source, usually a brushless DC motor (BLDC) or an AC servo motor. Such motors have high efficiency, long service life, fast response, and are easy to control. In order to obtain greater output torque, the motor is usually connected with a reducer. The reducer can reduce the speed while increasing the torque, so that the electric cylinder can handle heavier loads. In order to accurately control the position and speed, an encoder or other type of displacement sensor is installed inside or outside the electric cylinder. These sensors can provide real-time feedback of the position of the piston to the control system.

[0035] In this embodiment, when the platform truck 2 needs to be raised, the electric cylinder 13 receives instructions from the control module 5, the motor starts and pushes the scissor structure outward through the transmission mechanism, so that the platform truck gradually rises to the required height. Conversely, when the height of the platform truck 2 is to be lowered, the electric cylinder 13 operates in reverse, retracts the thrust, allows the scissor structure to contract, and eventually causes the platform truck to descend smoothly. Considering safety factors, the design of the electric cylinder 13 should also include overload protection, limit switches and other functions to prevent damage or danger in unexpected situations. In addition, the surface of the electric box 6 is also provided with an emergency switch 61 to ensure that power can be cut off immediately in case of a problem, ensuring the safety of the operator.

[0036] The platform truck 2 is provided with folding telescopic guardrails 3, which are rotatably connected to the platform truck 2 through hinges, and are fixed between adjacent folding telescopic guardrails 3 through buckles. The folding telescopic guardrails 3 can be folded, unfolded and telescoped according to actual conditions. The electric box 6 is fixed at the end of the platform truck 2, and the inside of the electric box 6 includes a battery and an electric control module. The surface of the electric box 6 is also provided with an emergency switch 61, a display screen 62 and a lifting switch 63. The electric control module is electrically connected with the battery, the emergency switch 61, the display screen 62 and the lifting switch 63, and the electric control module integrates a power management system, a controller, a drive circuit and a protection circuit. Figure 4 As shown in the figure, the electric box 6 is provided with handles 64 at both ends, which facilitate the forward and backward sliding of the platform truck 2 when it is raised.

[0037] The electric control module part mainly includes the following aspects:

[0038] Battery Management System (BMS): This is the core component that ensures the safe and reliable operation of the battery. The BMS can monitor the state of the battery in real time, such as temperature, voltage, current and other parameters, and take appropriate measures to protect the battery from overcharging, overdischarging, short circuit and other problems.

[0039] The controller plays the role of the brain, receiving various instructions from the operation interface or control module 5 and converting them into specific action commands sent to the motor, electric cylinder and other actuators. In addition, the controller is also responsible for coordinating the data processing of various sensors to ensure the stable operation of the system.

[0040] The drive circuit is used to amplify the small signal sent by the controller, so that it is sufficient to drive the high-power motor or other load. This part of the circuit usually contains MOSFET, IGBT and other power semiconductor devices.

[0041] The protection circuit includes but is not limited to overcurrent protection, overvoltage protection, undervoltage protection and other functions to prevent hardware damage or safety accidents caused by abnormal conditions.

[0042] The display screen control is responsible for driving the display screen 62 on the surface of the electrical box, displaying system status information such as remaining power, fault codes, etc.

[0043] The folding telescopic guardrail 3 is usually composed of multiple segments, each connected by sliding rails, allowing the guardrail to extend or retract in the vertical direction. These segments can be made of metal pipes (such as aluminum alloy, stainless steel) or high-strength plastic to ensure sufficient strength and durability. To achieve the folding function, the bottom of the folding telescopic guardrail 3 uses a hinge or pivot connector. These components allow the folding telescopic guardrail 3 to change angles, enabling the transition from an upright state to a flat state. The hinge design needs to consider fatigue resistance and corrosion resistance to adapt to frequent operation and different environmental conditions. When the guardrail is in the expanded state, a reliable locking mechanism is needed to fix its position. This can be done with built-in or external locks, which should be simple to use and secure, able to withstand a certain impact force without loosening. For the telescopic part, a nested tubular structure is used, with smaller pipes inserted into larger pipes, changing the overall length by stretching or compressing.

[0044] As shown in Figure 1 , 4 , the control module 5 is installed on one end of the flat car 2 by a fixed rod, and the control module 5 is provided with a handle 64 at both ends, and the handle 64 of the other end is sleeved with a handlebar 51, which controls the rotation of the drive wheel 22 through the handlebar 51, and the control module 5 is also provided with a button 52 for switching forward and backward. The handlebar 51 is usually composed of a shell, a rotating shaft, a potentiometer or a Hall Effect sensor, a button, and a connection cable. The shell material can be selected from durable and comfortable plastic or metal materials to ensure comfort and reliability after long-term use. The rotating shaft is fixed in the shell through a bearing and connected to the internal sensing element, allowing users to easily rotate without excessive friction.

[0045] Potentiometer: When using a potentiometer, as the angle of the handlebar 51 changes, its resistance value also changes accordingly, outputting different voltage signals to the control module 5. The control module adjusts the speed of the motor according to the different voltage levels received.

[0046] Hall Effect Sensor: A more advanced solution is to use a Hall Effect sensor, which can non-contact detect changes in magnetic field strength and then convert it into a digital signal to the control system. This method has higher precision and response speed, and is also more durable.

[0047] As shown in Figure 5 , 6As shown, a roller shutter module 4 is mounted on the fixed rod, and the roller shutter module 4 accommodates a roller shutter cloth, which is used to cover the cargo on the vehicle. Rolling shutter door mechanisms are widely used in building doors and windows, garage doors and other fields. The basic principle is to use spring tension or an electric motor to drive the reel to rotate, thereby rolling up or lowering the curtain cloth. For the roller shutter module in this embodiment, a design with a similar structure but smaller size can be selected. The roller shutter cloth material can be selected according to actual needs. Functional fabrics or plastic films such as waterproof and sun-proof can be selected to protect the cargo from environmental factors. The operation mode of the roller shutter can be manual pulling or electric control. The latter requires the additional configuration of a small motor and a corresponding control system.

[0048] In some embodiments, the chassis 11 may be equipped with rollers to facilitate the overall movement of the flatbed truck 2 when it is raised.

[0049] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, its principle is further explained below in combination with the usage method.

[0050] Under normal circumstances, the delivery cart Figure 6 As shown, fold the foldable and telescopic guardrail 3 and lifting module 1 completely and place them in the truck. When in use, ensure that the battery in the electrical box 6 is fully charged and confirm that all parameters are normal on the display 62. Check that all mechanical components are in good condition, especially the foldable and telescopic guardrail 3 and the roller blind.

[0051] After placing the delivery cart on the ground, partially unfold the telescopic guardrail 3 and secure it with a lock. Use the lift switch 63 on the electrical box 6 to adjust the height of the flatbed trolley 2 according to the required height of the loading and unloading platform. The electric cylinder 13 drives the scissor lift 12, smoothly completing the lifting action and bringing the flatbed trolley 2 to the required height.

[0052] After adjusting the height, slide the cigarette turnover box directly onto the cart or unload it from the cart. At this time, unfold the last folding telescopic guardrail and lock it with the adjacent folding telescopic guardrail to ensure the safety of the goods. Figure 1 shown.

[0053] After loading the goods, the scissor lift 12 is lowered. Figure 5 As shown, the roller blind of the roller blind module 4 is pulled out to achieve rain and sun protection.

[0054] The forward or reverse mode is selected by pressing the buttons 52 on the control module 5, and the speed is controlled by turning the handle 51. The motor in the driving wheel 22 drives the cart to move smoothly, and it can be flexibly operated even in a small space.

[0055] If you encounter an emergency, immediately press the emergency switch 61 on the electric box 6 to stop all actions to ensure safe operation.
