Description

Technical Field

[0001] This utility model relates to the field of electric forklift technology, specifically to a solar-powered electric forklift with retractable intelligent forks. Background Technology

[0002] In the industrial logistics sector, electric forklifts have become key equipment for material handling due to their core advantages of being environmentally friendly and efficient. With the advancement of global low-carbon transformation, the combination of solar energy, as a clean and renewable energy source, with electric forklifts has become a hot topic in technological development, forming a technical system with "solar power supply + electric forklift body" as the core architecture. This system mainly covers three technical branches, among which the basic solar-assisted power supply technology has been commercialized and is suitable for light-load, short-distance handling scenarios such as small warehouses and short-distance transfer of photovoltaic modules.

[0003] Most existing electric forklifts have fixed-length forks and insufficient energy supply stability, which leads to the following problems during use: First, poor adaptability, as the fork length cannot be adjusted according to the size of the goods (such as long and narrow goods or multi-piece combinations). When handling extra-long goods, uneven force can easily cause the goods to tilt and fall. When operating in confined spaces, the excessive length of the forks affects the flexibility of operation. Some electric forklifts with telescopic functions have insufficient stability of the telescopic mechanism. Some telescopic forks are guided by only a single guide rail, which can easily cause shaking and deformation when carrying heavy loads, affecting the safety of handling. At the same time, most existing products use conventional solar panels with a conversion rate of only 15%-20%, and rely on a passive power supply mode of "solar assistance and grid charging as a backup". The solar power supply fluctuates greatly due to changes in sunlight intensity and weather. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a solar-powered electric forklift with retractable intelligent forks, which can effectively solve the problems of poor adaptability, cumbersome operation, low safety and insufficient energy supply stability of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a solar-powered electric forklift with retractable intelligent forks, including a solar-powered electric forklift body, a mast assembly and a fork mounting plate. A mounting housing is fixedly connected to the side wall of the fork mounting plate. Two No. 1 forks are fixedly connected to the inner bottom surface of the mounting housing. A groove is provided on the upper surface of each of the two No. 1 forks, and a No. 2 fork is slidably connected in each of the two grooves. The intelligent telescopic mechanism includes a telescopic component and two reinforcing components. The telescopic component includes a first limiting groove formed on the adjacent side walls of two first forks. A first slider is slidably connected in each of the two first limiting grooves. The two first sliders are respectively fixedly connected to the side walls of two second forks. A movable seat is fixedly connected between the two first sliders. An electric cylinder is fixedly installed on the inner wall of the mounting housing. The output end of the electric cylinder is fixedly connected to the side wall of the movable seat.

[0006] According to the above-mentioned solar-powered electric forklift with retractable intelligent forks, the reinforcement component includes a second slide groove formed on the sidewalls of the two first forks away from each other. A second slider is slidably connected in the second slide groove. The second slider is fixedly connected to the sidewall of the second fork. An L-shaped reinforcement plate is fixedly connected to the sidewall of the second slider away from the second fork. The sidewall of the L-shaped reinforcement plate is fixedly connected to the sidewall of the second fork.

[0007] According to the above-mentioned solar-powered electric forklift with retractable intelligent forks, the two No. 1 forks are fixedly connected to the inner top surface of the mounting housing by multiple reinforcing ribs, and a connecting column is fixedly connected between the adjacent side walls of the two No. 1 forks.

[0008] According to the above-mentioned solar-powered electric forklift with retractable intelligent forks, two supporting housings are fixedly connected to the inner wall of the mounting housing, and a supporting column is slidably connected inside each of the two supporting housings. The side ends of the two supporting columns are fixedly connected to the side wall of the movable seat.

[0009] According to the aforementioned solar-powered electric forklift with retractable intelligent forks, both of the aforementioned support housings penetrate the side wall of the mounting housing and are located on both sides of the electric cylinder.

[0010] According to the above-mentioned solar-powered electric forklift with retractable intelligent forks, the L-shaped reinforcing plate is attached to the side wall of the first fork.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: This utility model uses a telescopic component to drive the moving seat to move horizontally under the control of an electric cylinder, which in turn drives the first slider to slide along the first limiting groove, thereby realizing the telescopic movement of the second fork along the groove of the first fork. At the same time, precise telescopic movement is achieved through electronic control, which can adapt to the handling needs of goods of different lengths without the need to replace the forks, thus improving operational flexibility.

[0012] This utility model, through the setting of reinforcement components, ensures that when the No. 2 fork extends or retracts, the No. 2 slider slides synchronously along the No. 2 slide groove, and the L-shaped reinforcement plate is always in contact with the outer wall of the No. 1 fork, forming a two-way limiting structure of "inner No. 1 slider guide and outer L-shaped plate reinforcement". Combined with the overall reinforcement of the reinforcing ribs and connecting columns, as well as the symmetrical support of the support shell and support columns on the moving seat, the fork does not shake significantly during transportation, thereby significantly improving load-bearing stability and structural durability.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Refer to Figures 1 to 5 A solar-powered electric forklift with extendable intelligent forks includes a solar-powered electric forklift body 1, a mast assembly 11, and a fork mounting plate 12. A mounting housing 13 is fixedly connected to the side wall of the fork mounting plate 12. Two first forks 14 are fixedly connected to the inner bottom surface of the mounting housing 13. Grooves 15 are formed on the upper surface of each of the two first forks 14, and second forks 16 are slidably connected within each of the two grooves 15. Multiple reinforcing ribs fix the two first forks 14 to the inner top surface of the mounting housing 13. Connecting posts 17 are fixedly connected between adjacent side walls of the two first forks 14. Multiple reinforcing structures enhance the stability of transport after the forks are extended. The solar-powered electric forklift body 1 consists of an electric forklift body, a high-efficiency solar panel with a conversion rate ≥25%, a kinetic energy recovery device, and a long-cycle-life lithium battery. The system consists of a battery and an intelligent energy storage management algorithm module (all components are existing technologies and will not be described in detail). The high-efficiency solar panel improves the light energy utilization rate by more than 25% compared to traditional products (15%-20% conversion rate), maximizing the capture of solar energy. The kinetic energy recovery device can recover an additional 10%-15% of the deceleration or downhill kinetic energy, reducing energy waste. The high-efficiency solar panel converts solar energy into electrical energy and stores it in the lithium battery, providing kinetic energy for the electric forklift body, mast assembly 11, and subsequent intelligent telescopic mechanism. The intelligent energy storage management algorithm module optimizes energy storage distribution in low-light scenarios such as cloudy days and nights, extending continuous operation time by 30%-40%, promoting the upgrade of forklifts from "auxiliary power supply" to "semi-independent / independent power supply", thereby significantly reducing downtime caused by charging and improving equipment utilization. The intelligent telescopic mechanism includes a telescopic component 2 and two reinforcing components 3. The telescopic component 2 includes a first limiting groove 21 opened on the adjacent side wall of the two first forks 14. A first slider 22 is slidably connected in each of the two first limiting grooves 21. The two first sliders 22 are respectively fixedly connected to the side wall of the two second forks 16. A movable seat 23 is fixedly connected between the two first sliders 22. An electric cylinder 24 is fixedly installed on the inner wall of the mounting housing 13. The output end of the electric cylinder 24 is fixedly connected to the side wall of the movable seat 23. Two support housings 34 are fixedly connected to the inner wall of the mounting housing 13. A support column 35 is slidably connected in each of the two support housings 34. The side ends of the two support columns 35 are fixedly connected to the side wall of the movable seat 23. The two support housings 34 penetrate the side wall of the mounting housing 13 and are located on both sides of the electric cylinder 24. The reinforcement component 3 includes a second slide groove 31 opened on the sidewalls of the two first forks 14 away from each other. A second slider 32 is slidably connected in the second slide groove 31. The second slider 32 is fixedly connected to the sidewall of the second fork 16. An L-shaped reinforcement plate 33 is fixedly connected to the sidewall of the second slider 32 away from the second fork 16. The sidewall of the L-shaped reinforcement plate 33 is fixedly connected to the sidewall of the second fork 16. The sidewall of the L-shaped reinforcement plate 33 close to the first fork 14 is in contact with the sidewall of the first fork 14. The L-shaped reinforcement plate 33 is always in contact with the outer sidewall of the first fork 14, which helps to improve the stability of the extended second fork 16.

[0019] The working principle of this utility model is as follows: When in use, the fork mounting plate 12 is installed in the mast assembly 11 and is driven by the hydraulic cylinder in the mast assembly 11 to achieve lifting and lowering. According to the length of the goods, the operator controls the required fork extension and retraction stroke through the forklift operation panel and starts the electric cylinder 24. The output end of the electric cylinder 24 pushes or pulls the moving seat 23 to move horizontally. The moving seat 23 drives the first slider 22 on both sides to slide along the first limit groove 21, and at the same time drives the support column 35 to slide synchronously along the support housing 34. The first slider 22 drives the second fork 16 to extend or retract along the groove 15 of the first fork 14 until the set stroke is reached. The electric cylinder 24 stops moving, and the length adjustment is completed. After adjustment, the operator moves the main body 1 of the solar-powered electric forklift to the cargo position, inserts the forks into the support points at the bottom of the cargo, ensures that the center of gravity of the cargo is between the two forks, and starts the lifting mechanism of the mast assembly 11 to lift the cargo to a safe height. During this process, the reinforcing component 3 and the support structure work together to prevent the cargo from swaying or the forks from deforming. The operator moves the main body 1 of the solar-powered electric forklift to the target position and slowly lowers the mast assembly 11 to place the cargo stably. If the fork length needs to be adjusted, the above adjustment steps can be repeated. After the operation is completed, the electric cylinder 24 is reset, which drives the second fork 16 to retract to the maximum extent into the groove 15 of the first fork 14, reducing the space occupied by the forks and making it easier for the forklift to move and store.

[0020] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
