[0034] Example 1

[0035] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a frame structure for a driver's cab, including a fixed frame 10, a support frame 20, and a protective frame 30. The fixed frame 10 includes a vertical adjusting frame 101 and at least one locking frame 102 for locking with the vehicle beam frame 1. The support frame 20 includes a base frame 201 and multiple bottom plate main beam frames 202 disposed in the middle of the base frame 201. The rear end of the base frame 201 is disposed on the fixed frame 10. A first reinforcing plate 203 is disposed at the connection position between the base frame 201 and the fixed frame 10, and a second reinforcing plate 2011 is disposed at the connection position between the base frame 201 and the bottom plate main beam frame 202. The protective frame 30 is disposed on the front end face of the base frame 201 and is a hollow structure.

[0036] Specifically, the support frame 20 and the fixed frame 10 can be connected by welding to ensure the stability of the connection. To avoid stress concentration at the welding point, the weld is reinforced with a first reinforcing plate 203 to distribute stress and improve the overall structure's durability and safety. Similarly, the foundation frame 201 and the main beam frame 202 of the base plate in the support frame 20 can also be connected by welding, and then reinforced with a second reinforcing plate 2011 to ensure uniform stress distribution and further enhance the overall structure's stability and impact resistance.

[0037] Furthermore, through the tight connection between the fixing frame 10 and the vehicle beam frame 1, multiple sets of bolts and nuts can be used to lock the locking frame 102 to the end of the vehicle beam frame 1, ensuring a firm and reliable connection while avoiding the front axle position of the vehicle, so that the entire cab frame structure can be installed on the vehicle beam frame 1 to form a whole. The design of the vertical adjustment frame 101 allows for flexible adjustment of the ground clearance of the support frame 20. For truck-type vehicles, the cab height can be lowered to facilitate entry and exit.

[0038] Furthermore, a protective frame 30 is installed on the front end face of the basic frame 201. The protective frame 30 can be a crash beam structure, made of high-strength materials. Its unique hollow design not only reduces the overall weight but also provides ample space for buffering deformation, effectively absorbing impact forces and improving the safety performance of the cab. In addition, the surface of the protective frame 30 is coated with an anti-corrosion coating to extend its service life and ensure structural stability even in various harsh environments.

[0039] like Figure 3 As shown, in this embodiment, the locking frame 102 includes a positioning part 1021 disposed on the adjusting frame 101 and a locking part 1022 disposed on the vehicle beam frame 1. The locking frame 102 has a Z-shaped structure and is provided with a plurality of locking holes 1023. The positioning part 1021 is used to lock the adjusting frame 101, and it can also be extended for welding connection with the support frame 20, improving the stability of the connection. The connection with the vehicle beam frame 1 is achieved through the locking part, and multiple sets of bolts and nuts are used to lock the connection at the corresponding locking holes 1023, ensuring a firm and reliable connection. Furthermore, the Z-shaped design of the locking frame 102 not only enhances the stability of the overall structure but also facilitates installation and disassembly, improving maintenance efficiency.

[0040] like Figure 2 and Figure 3As shown, in this embodiment, an L-shaped or wedge-shaped reinforcing plate 1011 is provided at the connection position between the adjusting frame 101 and the vehicle beam frame 1. The reinforcing plate 1011 has weight-reducing holes 1012. The reinforcing plate 1011 can be installed in conjunction with the locking frame 102, for example, by installing the reinforcing plate 1011 on a vertical rod of a Z-shaped structure to enhance the strength of the connection point. This improves the stability of the connection structure and ensures the safety of installation and use.

[0041] In this embodiment, the main beam frame 202 and the foundation frame 201 are both made of square steel, and the strength of the main beam frame 202 is greater than that of the foundation frame 201. The use of square steel not only reduces the overall weight but also improves structural rigidity and load-bearing capacity, ensuring stability even under complex road conditions. Furthermore, the central part of the cab in the support frame 20 is reinforced with the even stronger main beam frame 202, ensuring that the cab can effectively distribute force and reduce the risk of deformation when subjected to impact. Simultaneously, the square steel structure design of the main beam frame 202 and the foundation frame allows the overall structure to maintain high load-bearing capacity while being lightweight, further enhancing the safety and stability of the cab.

[0042] like Figure 4 As shown, in this embodiment, the protective frame 30 includes a first U-shaped plate 301 and a second U-shaped plate 302 that is interlocked and fixedly installed with the first U-shaped plate 301. The interlocking installation of the two U-shaped plates not only improves the strength of the anti-collision beam but also forms a multi-layered protective structure, effectively dispersing impact force. Simultaneously, the hollow design between the first U-shaped plate 301 and the second U-shaped plate 302 has a good impact energy absorption effect, further enhancing the buffering effect and improving safety. Furthermore, the anti-collision beam structure design with two U-shaped plates has a simple manufacturing process, low manufacturing cost, and light weight, while still meeting the anti-collision protection requirements.

[0043] like Figure 4 As shown, in this embodiment, the first U-shaped plate 301 or the second U-shaped plate 302 is provided with several locking holes (not shown), and the impact resistance height of the first U-shaped plate 301 is greater than or equal to 125mm. The locking holes are used for secure connection, allowing for easy disassembly and maintenance of the entire protective frame 30, ensuring convenient and stable connection. Furthermore, the height (and width) of the protective frame 30 can be designed to be 125mm to meet the relevant conditions of the EU regulation UNR93 for front lower protection.

[0044] like Figure 1 As shown, in this embodiment, the basic frame 201 is provided with a stepped structure 2012 facing one side. The design of the stepped structure 2012 can connect the driver's seat and the door position, further reducing the height of the driver's cab door and making it easier for the driver to get on and off the vehicle.

[0045] like Figure 1 As shown, in this embodiment, the top surface of the protective frame 30 is provided with a shelf 303. The shelf 303 is designed to form the floor structure of the cab, facilitating the subsequent installation of seats and various equipment. The shelf 303 is made of high-strength materials (such as steel plates) to ensure the stability and durability of the floor structure, thereby improving the comfort and safety of the cab. At the same time, the shelf 303 is designed to facilitate drainage and cleaning, making maintenance more convenient.

[0046] Example 2

[0047] This embodiment provides a vehicle including a cab frame structure as described in Embodiment 1, such as a truck cab frame structure. The cab structure is moved forward, and through the hook-and-loop structural design, the cab is more tightly connected to the cab and the front of the vehicle. At the same time, the ground clearance of the cab can be reduced, making it easier for the driver to enter and exit, and improving the safety of use.

[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
