Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a modular overhead guard system for industrial vehicles. Background Art

[0002] In modern logistics and industrial production, forklifts have become an indispensable tool for handling, with applications spanning warehousing, loading and unloading, production, and processing. However, due to the diversification of operational scenarios, the requirements for forklift functionality are constantly increasing. As a key feature of forklifts, lowered overhead guards offer significant advantages in specific operating environments.

[0003] First, in height-restricted working environments, such as low warehouses, workshops, or containers, a lowered overhead guard effectively reduces the forklift's overall height, allowing it to maneuver smoothly through low spaces and complete operations. Second, in specialized loading and unloading tasks requiring precise manipulation, a lowered overhead guard provides the operator with a wider field of view, making it easier to observe the cargo's position and handling status, thereby improving precision and safety. Furthermore, in operations requiring frequent turns and maneuvers within confined spaces, the lowered overhead guard design helps reduce the forklift's overall size, improving its maneuverability and ease of operation. Despite the aforementioned advantages of lowered overhead guards, current technical designs still have some shortcomings. For example, in practice, the operation and adjustment of lowered overhead guards often require complex mechanical or manual intervention, which not only reduces efficiency but also increases operating costs. Furthermore, existing designs often lack sufficient flexibility to accommodate varying height requirements, making it difficult to fully meet customer needs in a variety of scenarios. These issues limit the effectiveness of lowered overhead guards and represent an important area for technological improvement in the industry. Utility Model Content

[0024] The system provides a top structural frame through the frame assembly 1, and the extended top frame 11 forms the core load-bearing component, and is supported by the left rear leg 21 and the right rear leg 22 in the support assembly 2. The connecting mechanism 3 ensures a stable connection between the frame assembly 1 and the support assembly 2, and relies on a multi-point locking device to achieve fastening. At the same time, the elastic buffer absorbs vibration and impact, improving the stability and safety of the system. The standardized installation interface facilitates the rapid installation and replacement of the legs, thereby realizing the superiority of the modular design. The modular overhead guard system improves the applicability and maintenance convenience of industrial vehicles through modular design. The extended top frame 11 and the height matching of the legs achieve adaptability to a variety of vehicles, the elastic buffer improves the impact resistance of the structure, and the standardized interface simplifies the installation and maintenance process, reducing production and use costs.

[0025] In this embodiment, the frame assembly 1 and support assembly 2 can be made of various materials, such as aluminum alloy to reduce weight or high-strength steel to increase load-bearing capacity. The elastic buffer can be made of other flexible materials, such as polyurethane, to meet specific requirements. The standardized mounting interface can be modified to include quick-release pins or self-locking threaded devices to further optimize installation efficiency.

[0026] In one possible embodiment, the extended top frame 11 is composed of a plurality of modular units, and the modular units are detachably connected by quick connectors. The extended top frame 11 adopts a modular unit design and is connected by quick connectors. This design allows the extended top frame 11 to be adjusted, disassembled or reassembled as needed, so that the system can adapt to industrial vehicles of different specifications or uses. The quick connectors are made of high-strength materials to ensure the stability of the connection and the convenience of assembly and disassembly. The modular design improves the flexibility of the extended top frame 11 and facilitates its use in different work scenarios. The quick connectors enable the detachability of the frame, reducing the space required for transportation and storage, while simplifying the maintenance process.

[0027] Modular units can be configured in different lengths and shapes to suit specific vehicle designs. Quick connectors can be replaced with different types of connections, such as snap-fit ​​or slot-fit, to meet varying strength or assembly efficiency requirements.

[0028] In one possible embodiment, the left and right rear legs 21 and 22 are internally provided with reinforcing ribs. These ribs enhance the strength and rigidity of the legs by optimizing their internal geometry, such as by adding longitudinal and transverse ribs. This structural design effectively distributes and carries stress under load, enhancing bending resistance and durability. The ribs improve the strength and durability of the legs, ensuring system reliability under harsh operating conditions while maintaining the advantages of a lightweight design and reducing material costs.

[0029] The shape and layout of the rib structure can be adjusted to meet specific needs, such as adding cross-ribs to enhance multi-directional rigidity. The rib material can also be replaced with composite materials to further improve corrosion resistance and reduce weight.

[0030] In one possible embodiment, the multi-point locking device in the connecting mechanism 3 includes a plurality of clips and locking bolts. The multi-point locking device works through a combination of clips and locking bolts. The clips provide preliminary positioning and connection, and the locking bolts ensure final tightening and stability. Through the multi-point locking design, the system can withstand impact forces and vibrations in multiple directions. The multi-point locking device improves the connection strength and stability of the system, especially in high-load or vibration environments, ensuring the firmness and durability of the overhead guard. The shape and number of the clips can be adjusted according to needs, such as adding spring clips to improve the tightness of the connection. The locking bolts can be replaced with hydraulic bolts or automatic locking devices to improve assembly efficiency.

[0031] In one possible embodiment, the elastic buffer is made of a rubber material or a composite elastic material. The elastic buffer utilizes the high elasticity and shock-absorbing properties of rubber or composite elastic materials to absorb vibration and impact, thereby protecting the structural integrity of the frame assembly and support assembly and extending the life of the system. Rubber materials are low-cost and simple to process, while composite elastic materials offer both high strength and durability. This buffer design enhances the stability and durability of the overhead guard system. The elastic buffer material can be replaced with silicone rubber or polymer materials to meet the anti-aging or high-temperature resistance requirements of different environments.

[0032] In one possible implementation, the bottom standardized mounting interface of the left rear leg 21 and the right rear leg 22 includes pin holes and threaded connectors for quick docking. The standardized mounting interface achieves quick docking through the combined design of pin holes and threaded connectors. The pin holes are used for preliminary positioning and provide lateral fixation, and the threaded connectors are used for final fastening and stabilization. This design simplifies the installation process while ensuring the stability of the system in different use environments. The combined design of pin holes and threaded connectors significantly improves installation efficiency, shortens installation time, and allows repeated disassembly, facilitating maintenance and replacement. Such a standardized interface is highly versatile and suitable for a variety of industrial vehicles.

[0033] The shape of the pin holes can be adjusted to be oval to accommodate a range of assembly errors, and the threaded connectors can be replaced with quick pins or latching structures to further improve assembly convenience.

[0034] In one possible implementation, the surfaces of the frame assembly 1 and the support assembly 2 are covered with a corrosion-resistant coating. The corrosion-resistant coating forms a protective film on the surface of the frame assembly 1 and the support assembly 2 through physical or chemical means, preventing the invasion of moisture, salt, or other corrosive substances. The coating can be completed using processes such as spraying, dipping, or electrophoretic coating to ensure coating uniformity and adhesion. The corrosion-resistant coating significantly extends the service life of the system in harsh environments, reduces maintenance costs caused by corrosion, and maintains the stability of the structural appearance and mechanical properties.

[0035] The coating material can be replaced with a ceramic coating or a polymer coating to enhance wear resistance. The coating process can use nano-spraying technology to improve the density and durability of the coating.

[0036] In one possible implementation, the two ends of the elongated top frame 11 are provided with reinforced fixing plates. The reinforced fixing plates are firmly connected to the two ends of the elongated top frame 11, increasing the overall strength and rigidity of the frame. This design effectively reduces deformation or displacement of the frame caused by uneven load during use. The reinforced fixing plates improve the anti-twist ability of the elongated top frame, allowing the system to maintain stability and shape integrity over a long period of use. In addition, this design is particularly suitable for high-load environments, enhancing the reliability of the system.

[0037] The material of the reinforced fixing plate can be selected as aluminum alloy to reduce weight, or composite material to improve corrosion resistance. The shape and thickness of the fixing plate can be optimized according to actual application requirements.
