[0030] like Figures 1-5As shown, a passenger seat and storage box integrated structure includes a cushion assembly 2, a storage box assembly 4, and a seat belt device 3;
[0031] The cushion assembly 2 includes a cushion mounting bracket 21 and a cushion. The cushion mounting bracket 21 is connected to the cushion, and the cushion mounting bracket 21 and the cushion are detachably connected to the rear panel 1 of the cab. The cushion mounting bracket 21 serves as the core connection, forming an integral support with the cushion and being fixed to the rear panel 1 of the cab via a detachable connection (such as a bolt connection). This ensures the stability of the cushion when seated. The detachable design facilitates installation, disassembly, and maintenance, reducing maintenance costs. Furthermore, the independent detachable connection between the cushion and the cushion mounting bracket 21 allows for the replacement of the cushion individually (e.g., when worn or damaged) without replacing the entire assembly, thus improving economy.
[0032] The storage box assembly 4 includes a seat cushion 41, a rear support 42, multiple mounting brackets, and a front upright plate 46. The rear support 42 is detachably mounted on the rear bulkhead 1 of the cab, and the front upright plate 46 is detachably mounted on the vehicle floor. The front upright plate 46 and the rear support 42 are connected by multiple mounting brackets to form a frame structure. The interior of the frame structure is a storage space, and the top forms a seat support surface. The seat cushion 41 is placed on the seat support surface and cooperates with the backrest assembly 2 to form a seat structure. Through the frame structure in the storage box assembly 4 (composed of the front upright plate 46, the rear support 42, and multiple mounting brackets), the dual functions of storage and seating are realized, solving the pain point of limited cab space.
[0033] The seat belt device 3 includes a buckle 31 and a seat belt assembly 32. The buckle 31 and the seat belt assembly 32 are directly installed on the rear panel 1 of the cab. The connection point is a rigid structure of the vehicle body with high strength. When the vehicle is in motion (especially on complex road conditions such as off-highway dump trucks), it can effectively restrain the driver and passengers, reduce body sway during collisions or bumps, and ensure personal safety. In addition, the installation position of the seat belt device 3 (rear panel 1 of the cab) is concentrated with the fixing points of the backrest assembly 2 and the storage box assembly 4, avoiding additional drilling or welding in other parts of the vehicle body, reducing damage to the vehicle body structure, and making the interior layout of the cab simpler and not occupying extra space.
[0034] In some embodiments, the cushion is either a separate piece or a single piece, such as... Figure 2As shown, the cushion is a split type, including an upper cushion 22 and a lower cushion 24, which can be flexibly adjusted according to the size of the cab space and usage scenarios (such as passenger carrying or temporary storage needs) to adapt to different vehicle models or user needs. The cushion mounting bracket 21 is a frame type and is fixed to the cushion by bolts. The interior of the cushion has an iron liner, the surface of which is covered with sponge, and the exterior is covered with leather or fabric. This utility model uses a frame-type cushion mounting bracket 21 to provide rigid support and prevent the cushion from deforming under stress. The iron liner further enhances the support strength, while the sponge and covering fabric ensure riding comfort, thus achieving a balance between hard support and soft experience.
[0035] In some embodiments, such as Figure 4 As shown, the mounting brackets include a right mounting bracket 43, a middle mounting bracket 44, and a left mounting bracket 45. One end of each mounting bracket is bolted to the top of the front upright plate 46, and the other end is bolted to the rear bracket 42. The right mounting bracket 43 and the left mounting bracket 45 have the same structure and are symmetrically distributed. Through this design, the rear bracket 42, which is fixed to the rear bulkhead 1 of the cab, and the front upright plate 46, which is fixed to the vehicle floor, are connected by the right, middle, and left mounting brackets to form a stable frame structure with high overall strength. This structure can bear the weight of the driver and passengers, effectively preventing deformation and damage. Furthermore, the symmetrical layout of the left and right mounting brackets ensures balanced force distribution, further enhancing the stability of the frame.
[0036] In some embodiments, one end of the seat cushion 41 is hinged to the top of the frame structure, making it easy to open and retrieve items from the storage space without disassembling the seat cushion, thus balancing ease of use. The hinged design also allows the seat cushion 41 to switch freely between seat mode and storage mode without affecting each other. When used as a seat, it provides stable support; when storage is needed, simply flipping the seat cushion 41 does not require altering the overall structure, fully demonstrating the flexibility of the integrated design. The size of the seat cushion 41 is adapted to the top of the frame structure, ensuring flatness and support stability when used as a seat, avoiding wobbling or discomfort due to size mismatch. When closed, it tightly covers the top of the frame, forming a closed storage space to prevent items from falling or dust from entering, thus balancing the integrity of both seat and storage functions.
[0037] In some embodiments, the rear bracket 42 is connected to the rear cab 1 via bolts or screws, and the bottom of the front upright plate 46 is connected to the vehicle floor via bolts or screws. The use of bolts or screws enables a detachable connection, facilitating easy assembly and disassembly. During the production assembly stage, the positions of the rear bracket 42 and the front upright plate 46 can be fine-tuned by adjusting the tightness of the connectors, ensuring the connection accuracy between them and the rear cab 1 and the vehicle floor. This guarantees the installation accuracy of the entire frame structure and reduces functional problems caused by assembly errors. Furthermore, when a single component (such as the rear bracket 42, the front upright plate 46, or associated mounting brackets) is damaged, there is no need to disassemble or replace the entire integrated structure; only the corresponding connector needs to be removed for individual repair or replacement. This significantly reduces maintenance difficulty and cost, shortens repair time, and improves equipment turnaround efficiency. Additionally, the front upright plate 46 can be flexibly fitted with cable routing holes and weight-reduction holes according to actual layout requirements.
[0038] In some embodiments, the seat belt assembly 32 is a two-point seat belt or a three-point seat belt, which can flexibly adapt to the safety regulations and standards of different regions (such as the mandatory requirements for vehicle seat belts in different countries or industries), and can be specifically selected according to actual usage scenarios (such as the complex road conditions of off-highway dump trucks, the riding habits of drivers and passengers, etc.). This design avoids the limitations of a single type of seat belt, significantly improves the adaptability of the entire integrated structure in different application scenarios, and makes the product more versatile and practical.
[0039] The second aspect of this utility model is as follows: Figure 5 As shown, a cab is also provided, including a driver's seat 5. The cab is equipped with the aforementioned integrated structure of the passenger seat and storage box, located behind the driver's seat 5. This invention places the integrated structure of the passenger seat and storage box behind the driver's seat 5, making full use of the unused space at the rear of the cab and avoiding the space waste caused by the traditional separate placement of independent seats and storage boxes. The integrated structure itself combines seating and storage, further reducing the overall volume occupied by functional components, making the cab layout more compact and orderly, especially suitable for vehicles with limited space (such as off-highway dump truck cabs). Simultaneously, the driver's seat 5, as the main operating area, is located at the front, while the rear integrated structure focuses on passenger seating and storage functions, forming a clear functional zoning. When operating from the driver's seat, the driver and passengers are not disturbed by the rear structure, and when retrieving items from the storage space or using the passenger seat, they do not need to cross the core driving area, resulting in a more rational workflow and improved ease of use. In addition, the front and rear layout of the integrated structure and driver's seat 5 makes the installation points of the internal components of the cab (such as the connection between the integrated structure and the rear wall of the cab and the vehicle floor) more concentrated, reducing the scattered damage to the vehicle structure. The seat belt device 3 of the integrated structure complements the safety facilities in the driver's seat area, improving the overall safety protection level of the cab.
[0040] Finally, in a third aspect, this utility model also provides an off-highway dump truck equipped with the aforementioned cab, such as the XCMG DM530T and XG110 models exported to Brazil, which employ an offset narrow-body cab. By installing the aforementioned cab, the off-highway dump truck can fully utilize the integrated structure of the passenger seat and storage compartment within the cab, balancing passenger and storage functions within a limited cab space, thus meeting the needs for space utilization and storage of onboard items in engineering operations. Simultaneously, the rational layout and safety design of the cab improve driving safety and convenience under complex off-highway road conditions, enhancing the overall practicality and adaptability of the vehicle.
[0041] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features found in other embodiments but not others, combinations of features from different embodiments are also within the scope of protection of this utility model and form different embodiments. For example, in the embodiments described above, those skilled in the art can use them in combination based on known technical solutions and the technical problems to be solved by this application.
