[0002] The overhead frame of a forklift cab, typically located above the driver's head, is an upper protective structure welded from steel pipes, structural steel, or steel plates. This structure is generally connected to the front and rear uprights of the cab, forming a stable spatial frame. Its main function is to effectively prevent goods from accidentally falling and striking the driver during lifting and handling. It also provides cushioning and support in the event of a forklift rollover or collision, thereby reducing the risk of injury to the driver. The overhead frame is not only a fundamental safety component of the forklift cab but also a crucial indicator of a forklift's safety performance. Most existing roof racks are fixed welded structures. Due to the significant differences in the size and structure of roof racks for different vehicle models, protective components are often not interchangeable. This results in the need for special customization when adding or replacing them, leading to complex installation and difficult disassembly, making it difficult to meet the needs of multi-vehicle compatibility and convenient use.

[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 following is combined with Figures 1-5 This invention describes the top frame structure of a forklift cab.

[0018] In one embodiment, a top frame structure for a forklift cab includes: a top frame 100, with two fixed seats 200 fixedly installed on both sides of the top frame 100, and two reinforcing ribs 210 provided between the two fixed seats 200 on the same side; a modular protection mechanism 300, which is used to provide quick modular connection protection for different top frames 100, and is disposed between the two fixed seats 200 on the same side; wherein, the modular protection mechanism 300 includes a mounting seat 310 disposed on an adjacent side of the two fixed seats 200 on the same side, a modular assembly 320 disposed between the two mounting seats 310, and a mounting assembly 330 disposed between the mounting seat 310 and the adjacent fixed seat 200.

[0019] In this embodiment, by setting fixed seats 200 on both sides of the top frame 100 and arranging reinforcing ribs 210 between two fixed seats 200 on the same side, the overall structural strength and stability of the top frame 100 can be effectively improved, avoiding deformation caused by uneven stress. The modular protective mechanism 300 allows the mounting seat 310 to be quickly connected to the fixed seat 200 through the mounting component 330, thereby ensuring that the installation process of the protective structure is simple and efficient. The modular component 320 can be adjusted according to the width or spacing of different top frames 100, thereby achieving compatibility with top frames 100 of different models of forklift cabs, effectively solving the problem that existing protective components are not universal. It should be noted that the existing forklift cab top frame 100 consists of a front column, a rear column, and a transversely connected top beam, which is fixed on both sides by welding or bolting to form a stable frame structure. Its main function is to withstand the impact load when goods fall or the vehicle overturns, thereby ensuring the safety of the driver. This structure has been widely used in long-term applications and has good strength and reliability. The module component 320 is adjusted by being positioned between two fixed seats 200 on the same side. Its main function is to provide adaptation space according to the size differences of different top frames 100. The adjustment process is limited to the protective component itself and will not change the original force path and load-bearing characteristics of the top frame 100. The mounting component 330 is used to connect the mounting seat 310 to the fixed seat 200. It is arranged in parallel with the main structure of the top frame 100 and will not affect the load-bearing capacity or rigidity of the top frame 100.

[0020] The module assembly 320 includes a first protective plate 321 and a second protective plate 322, which are respectively fixedly installed on adjacent sides of two mounting bases 310. The first protective plate 321 and the second protective plate 322 are staggered and the sides of the first protective plate 321 and the second protective plate 322 that overlap each other are in contact with each other.

[0021] In this embodiment, during use, the length of the protective component can be adjusted by simply overlapping the first protective plate 321 and the second protective plate 322 according to the width of the top frame 100, thereby adapting to top frames 100 of different specifications and forming a continuous and reliable protective surface during protection, thus improving the lateral protection effect.

[0022] A fixing block 323 is fixedly installed on one side of each of the two mounting bases 310. A threaded tube 324 is rotatably installed on one side of one fixing block 323, and a screw 325 is fixedly installed on one side of the other fixing block 323. One end of the screw 325 is threadedly connected to the adjacent threaded tube 324.

[0023] In this embodiment, during use, rotating the threaded tube 324 drives the threaded screw 325 to extend and retract, thereby changing the distance between the two mounting seats 310. This not only allows for quick adaptation to different widths of the top frame 100, but also provides a simple and intuitive adjustment method that can be completed without complex tools. The self-locking characteristic of the threaded pair also ensures that the adjusted protective structure remains stable and reliable during use, preventing loosening or displacement.

[0024] On the side of the first protective plate 321 and the second protective plate 322 that are far apart from each other, telescopic belts 328 are fixedly installed. The side of the two telescopic belts 328 that are far apart from each other is fixedly connected to the adjacent mounting base 310. The two telescopic belts 328 are sleeved on the outside of the two reinforcing ribs 210, and the two reinforcing ribs 210 are fixedly connected to the mounting base 310 on one side.

[0025] In this embodiment, the first protective plate 321 and the second protective plate 322 are connected to the mounting base 310 via a telescopic belt 328. The telescopic belt 328 can freely extend and retract during installation or adjustment to adapt to the spacing requirements of different top frames 100. At the same time, the telescopic belt 328 is fitted on the outside of the reinforcing rib 210, so that the protective plate is always guided and supported by the reinforcing rib 210 during extension and retraction adjustment, avoiding swaying or displacement.

[0026] A transparent plate 327 is fixedly installed on the top of both the first protective plate 321 and the second protective plate 322, and the two transparent plates 327 are arranged alternately.

[0027] In this embodiment, the tops of the first protective plate 321 and the second protective plate 322 are staggered and covered by transparent plates 327, which can form a protective surface while ensuring that the driver's field of vision is unobstructed. The staggered structure allows the transparent plates 327 to overlap each other, further improving the integrity and stability of the protective surface, effectively blocking falling objects while also ensuring safety and a wide field of vision. It should be noted that the transparent panel 327 can be a transparent protective component, and its material can be a high-strength transparent material such as polycarbonate sheet, tempered glass, or acrylic sheet. Among these, polycarbonate sheet is more commonly used due to its high impact resistance and good light transmittance. The transparent panel 327 is usually a rectangular or near-rectangular flat plate structure, and its thickness can be selected according to actual usage requirements. It can provide effective protection against external impacts or falling objects while ensuring that the driver has a good field of vision during operation, thus balancing safety and ease of operation.

[0028] A protective sleeve 326 is fixedly installed between the two fixing blocks 323. The protective sleeve 326 is fitted over the outside of the threaded tube 324 and the screw 325.

[0029] In this embodiment, the protective sleeve 326 is a telescopic sleeve, which, after installation, can fully cover the threaded tube 324 and the screw 325, effectively preventing external dust and debris from entering the threaded pair and reducing wear and jamming. Simultaneously, the telescopic sleeve can extend and retract with the screw 325 during adjustment, without affecting the normal operation of the threaded tube 324 and the screw 325, thus ensuring a smooth adjustment process.

[0030] The mounting assembly 330 includes a connecting frame 331 fixedly mounted on the adjacent side of the two mounting bases 200, and a connecting block 332 fixedly mounted on the side of the two mounting bases 310 that is far apart from each other.

[0031] In this embodiment, during installation, simply adjust the first protective plate 321 and the second protective plate 322 to the appropriate positions, and then slide the two connecting blocks 332 along the connecting frame 331 to complete the connection. The operation is simple and quick. The inner wall of the connecting frame 331 is made of flexible material, which can provide buffering and friction during the insertion process. This not only makes the connection more stable and reliable and prevents loosening, but also reduces wear during the assembly process, and improves service life and maintenance convenience.

[0032] The connecting block 332 is set to a T-shape, and the shape of the connecting frame 331 is adapted to the connecting block 332.

[0033] In this embodiment, the connecting block 332 adopts a T-shaped structure and is adapted to the shape of the connecting frame 331, so that it can achieve quick alignment and limit during sliding insertion, avoiding misalignment or detachment.

[0034] Working principle: Two fixed seats 200 are pre-fixed on both sides of the top frame 100, and reinforcing ribs 210 are arranged between the fixed seats 200 on the same side to ensure the stability and load-bearing capacity of the overall structure of the top frame 100. When the module protection mechanism 300 needs to be installed, the operator connects the mounting seat 310 to the corresponding fixed seat 200 through the mounting component 330. In this process, the connection block 332 on the mounting seat 310 is simply slid into the connecting frame 331 to complete the insertion. The flexible inner wall can provide cushioning and friction during the assembly process, which not only avoids wear between parts, but also ensures a stable and reliable connection. Since the connecting block 332 adopts a T-shaped structure and is adapted to the connecting frame 331, it can be quickly aligned, avoiding misalignment or loosening. Subsequently, the operator adjusts the module assembly 320 according to the width or spacing requirements of different top racks 100. The first protective plate 321 and the second protective plate 322 contact each other at their overlapping points, and the length can be adjusted by changing the overlap length to adapt to the top racks 100 of different forklift models. To further improve the adaptability, the screw 325 can be extended or retracted by rotating the threaded tube 324, thereby finely adjusting the spacing between the two mounting seats 310 to ensure the stability of the protective components under different working conditions. The self-locking characteristic of the threaded pair ensures that the structure will not loosen after adjustment, improving reliability. The transparent plates 327 fixed to the top of the first protective plate 321 and the second protective plate 322 cover each other in an alternating manner, forming a complete protective surface that effectively blocks falling objects while ensuring a clear and unobstructed view for the driver.
