[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] like Figure 1 As shown, this utility model provides a forklift overhead guard, including a top cover plate 2, a glass skylight 3, and multiple sets of snap-fit ​​components.

[0025] Specifically, the top cover plate 2 is disposed on the top of the overhead guard frame 1 of the forklift and connected to the overhead guard frame 1. The top cover plate 2 has a through hole, and the edge of the through hole is recessed downward to form a stepped groove. The glass skylight 3 is made of multiple layers of glass stacked together. The glass skylight 3 is disposed inside the stepped groove. Multiple sets of snap-fit ​​components are disposed on the top of the top cover plate 2. The snap-fit ​​components are used to cooperate with the stepped groove to limit and fix the glass skylight 3.

[0026] In the forklift overhead guard provided by this utility model, the glass sunroof 3 is installed by designing stepped grooves on the top cover plate 2. This not only provides stable support but also ensures the safety of the glass sunroof 3 after installation, preventing it from falling off due to vibration or external force during forklift operation. Furthermore, the glass sunroof 3 is fixed and limited by the engagement component that cooperates with the stepped groove, further improving the stability of the glass sunroof 3 after installation.

[0027] Understandably, the depth and width of the stepped groove, as well as the transitions between each step, should ensure a tight fit to the glass skylight 3 while preventing damage due to excessive pressure during installation. The edges of the stepped groove can be rounded to reduce the risk of scratching the glass edges during installation and disassembly.

[0028] The snap-fit ​​assembly can be made of high-strength plastic or lightweight metal and can be configured with any suitable structure known to those skilled in the art, facilitating locking and unlocking of the glass skylight 3 from the top of the top cover plate 2. The snap-fit ​​assembly may be equipped with an elastic element to ensure that the glass skylight 3 maintains a stable and moderate clamping force after installation, preventing loosening. Multiple sets of snap-fit ​​assemblies can be evenly distributed around the outer perimeter of the glass skylight 3, distributing the load of the glass skylight 3 to multiple support points on the top cover plate 2, reducing localized stress concentration, and preventing warping or abnormal noise of the glass skylight 3 due to forklift vibration or temperature changes.

[0029] At the edge where the stepped groove meets the glass sunroof 3, high-quality waterproof sealant can be applied or a sealing strip can be installed to prevent rainwater from seeping into the vehicle and protect the vehicle's electronic equipment from being affected.

[0030] In order to maximize the visual boundary of the forklift cab space, in some embodiments, the glass skylight 3 may occupy 55% of the area of ​​the top cover 2.

[0031] To quickly remove water or snow from the sunroof 3 during rain or snow and ensure unobstructed forklift visibility, in some embodiments, a windshield wiper 4 is installed on the upper surface of the top cover 2. The drive arm of the wiper 4 is fixed above the rear edge of the sunroof 3, and the wiper blade is set at a 15° angle to the surface of the sunroof 3. This 15° angle helps the wiper blade to more effectively adhere to the surface of the sunroof 3, thereby improving cleaning efficiency.

[0032] The drive arm can be installed using a high-strength aluminum alloy or composite material bracket. The drive arm hinge point is fixed to the top of the rear edge of the glass sunroof frame 3, and the tilt angle is controlled at 15° through a double linkage or parallel arm mechanism.

[0033] In addition, a rotary bearing can be added at the connection between the drive arm and the wiper blade, allowing for fine adjustment of the wiper blade angle according to the curvature of the sunroof 3, ensuring a good fit throughout the entire stroke.

[0034] Wiper blades can be made of a combination of TPU (thermoplastic polyurethane) and stainless steel frame, which has both flexibility and anti-aging properties. The surface can be coated with a nano hydrophobic coating to enhance the drainage capacity.

[0035] In this utility model, such as Figure 2 As shown, the snap-fit ​​assembly includes a mounting clip 5. One end of the mounting clip 5 is fixed to the top cover plate 2, and the other end extends to the upper surface of the glass skylight 3, pressing the glass skylight 3 into the stepped groove. The mounting clip 5 structure simplifies the installation process of the glass skylight 3, allowing for pressing and fixing without complex tools, while also supporting quick disassembly for easy maintenance or replacement of the glass skylight 3.

[0036] Furthermore, the lower surface of the mounting clip 5 is provided with a limiting boss 51 extending into the stepped groove. The limiting boss 51 can limit the displacement range of the mounting clip 5 and the glass sunroof 3, preventing the clip from accidentally slipping off or the glass sunroof 3 from sliding due to forklift vibration or impact. At the same time, the cooperation between the limiting boss 51 and the stepped groove can help to align the glass sunroof 3 horizontally during installation and avoid tilting.

[0037] Furthermore, the snap-fit ​​assembly also includes a shock-absorbing pad 52, which is disposed between the other end of the mounting clip 5 and the upper surface of the glass sunroof 3. The shock-absorbing pad 52 absorbs the high-frequency vibration energy during vehicle operation through a flexible material (such as silicone), reduces the rigid contact between the glass sunroof 3 and the roof panel 2, reduces abnormal noise, and at the same time disperses the pressure exerted by the mounting clip 5 on the edge of the glass sunroof 3.

[0038] Understandably, the mounting clip 5 can be made of engineering plastic injection molding, with built-in stainless steel inserts to enhance its resistance to deformation. The mounting clip 5 can be equipped with anti-misalignment features that cooperate with the top structure of the top cover plate 2 to help with installation positioning and avoid incorrect installation. For example, a positioning pin can be set at the bottom of the mounting clip 5 to match the pre-drilled hole in the top cover plate 2, or a positioning hole can be set at the bottom of the mounting clip 5 to cooperate with the pre-set positioning post at the top of the top cover plate 2.

[0039] In some embodiments, a rubber pad 21 is provided at the edge of the stepped groove, and the rubber pad 21 has a U-shaped cross-section. The rubber pad 21 can absorb the impact force during the installation of the glass skylight 3, avoid rigid contact between the edge of the glass skylight 3 and the stepped groove, and the U-shaped opening design can directly wrap around the edge of the stepped groove, which is convenient for installation and provides a buffer protection for the glass skylight 3.

[0040] In addition, the U-shaped cross section of the rubber pad 21 and the stepped groove form a continuous sealing line. Combined with its compression deformation capability, it can, to a certain extent, prevent rainwater from penetrating into the gap between the top cover plate 2 and the glass skylight 3.

[0041] In some embodiments, the thickness of the top cover plate 2 is 4 mm.

[0042] like Figure 3 As shown, in some embodiments, the glass skylight 3 includes an outer glass layer 31, a first membrane layer 32, a middle glass layer 33, a second membrane layer 34, and an inner glass layer 35 arranged sequentially from top to bottom.

[0043] The glass sunroof 3 is designed as a composite layer structure formed by three layers of glass and a film. The outer glass 31, the middle glass 33, and the inner glass 35 can all be made of 5mm thick chemically tempered glass to improve the surface hardness and scratch resistance of the glass sunroof 3. In addition, a first film 32 and a second film 34 are respectively set between the three layers of glass. The film material can be PVB polyvinyl butyral, which has strong adhesion, and the film thickness is 0.76mm to prevent the glass sunroof 3 from delaminating and slipping. At this time, the total thickness of the glass sunroof 3 is 16.52mm. When the outer glass 31 is impacted and breaks, the PVB film can adhere the fragments and absorb the impact energy to prevent glass shards from flying and injuring people. In addition, the UV blocking performance of the PVB film can reduce the UV intensity inside the forklift and delay the aging of the interior. In summary, the three-layer design with a total thickness of 16.52mm significantly improves the overall penetration resistance of the glass sunroof 3, which can meet the passive safety requirements under high-speed collisions. In addition to its strong impact resistance, it also has excellent UV protection performance.

[0044] In this invention, the glass skylight 3 is set to be about 3mm higher than the top cover plate 2 after installation, which can prevent water accumulation on the top of the glass skylight 3 from affecting the view. In some embodiments, the edges of the glass skylight 3 are treated with anti-corrosion treatment (such as impregnation with epoxy resin) to prevent rainwater from penetrating and causing the diaphragm to delaminate.

[0045] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
