[0002] With the development of technology and the improvement of people's living standards, vehicles have become an indispensable means of transportation. The vehicle cabin provides a driving and riding environment, offering a safe and comfortable space for the driver and passengers. The windshield assembly at the front of the cabin can block wind, rain, and other foreign objects from entering the vehicle, preventing them from causing injury to the occupants.

[0003] In related technologies, most vehicle designs improve the structural strength of the front of the vehicle by increasing the thickness of the lower crossbeam of the windshield or by adding support brackets. However, changing the thickness of the lower crossbeam requires corresponding design changes to the body and surrounding parts molds, which is not only costly and time-consuming, but also makes the bracket design difficult due to the need for suitable space and support points. Such design and manufacturing methods will significantly increase the manufacturing cost and weight of the vehicle. Utility Model Content

[0032] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0033] The following is for reference. Figures 1-4 The cockpit 100 according to an embodiment of the present invention is described. The cockpit 100 can be applied to a vehicle.

[0034] Combination Figures 1-4 As shown, the cockpit 100 according to this utility model mainly includes: a cockpit body 10 and a roof assembly 20. The cockpit body 10 includes sill beams 101, a front bulkhead 102, and a rear bulkhead. Two sill beams 101 extend in the front-rear direction and are spaced apart in the left-right direction. The front bulkhead 102 connects between the two sill beams 101 and is located adjacent to the front end of each sill beam. The rear bulkhead connects between the rear ends of the two sill beams 101. This allows the sill beams 101, the front bulkhead 102, and the rear bulkhead to collectively form a cockpit body 10 frame with a certain strength. In the event of a vehicle collision, the sill beams 101, the front bulkhead 102, and the rear bulkhead work together to prevent or reduce deformation of the cockpit 100 by absorbing energy, dispersing impact force, and maintaining structural stability, thereby protecting passenger safety.

[0035] The roof assembly 20 includes a roof component 201 and a windshield component 202. The roof component 201 is positioned above the passenger compartment body 10, and its rear end is connected to the rear bulkhead. Specifically, by positioning the roof component 201 above the passenger compartment body 10, it not only prevents falling branches, stones, and debris such as wind and rain from entering the passenger compartment 100, thus protecting the safety of passengers, but also provides some heat insulation and maintains a comfortable interior environment. Furthermore, connecting the rear end of the roof component 201 to the rear bulkhead helps maintain the overall shape of the vehicle, providing strength and stability to the body structure.

[0036] The windshield assembly 202 includes a reinforcing beam, which includes a first reinforcing beam segment 2021 and a second reinforcing beam segment 2022. The first reinforcing beam segment 2021 extends in the left-right direction and is located at the front end of the roof assembly 201. There are two second reinforcing beam segments 2022, which are spaced apart in the left-right direction. The upper ends of the two second reinforcing beam segments 2022 are respectively connected to the left and right ends of the first reinforcing beam segment 2021, and the lower ends of the two second reinforcing beam segments 2022 are respectively connected to the front ends of the two sill beams 101. The two second reinforcing beam segments 2022 and the first reinforcing beam segment 2021 are integrally formed structural components. Specifically, by extending the first reinforcing beam segment 2021 in the left-right direction and setting it at the front end of the roof assembly 201, and connecting the upper ends of the two second reinforcing beam segments 2022, which are spaced apart in the left-right direction, to the left and right ends of the first reinforcing beam segment 2021 respectively, the first reinforcing beam segment 2021 and the two second reinforcing beam segments 2022 can effectively absorb and disperse collision energy when the vehicle collides, preventing or reducing the deformation of the windshield assembly 202. This not only improves the strength and stability of the windshield assembly 202 structure, but also better protects the glass in the center of the windshield assembly 202, preventing the windshield glass from breaking or falling off, thereby affecting the driver's vision or scratching passengers, and improving the safety of the vehicle structure. In addition, the lower ends of the two second reinforcing beam segments 2022 are respectively connected to the front ends of the two sill beams 101, which can form a more stable vehicle frame. When the vehicle collides, the impact force generated by the collision can be transferred between the reinforcing beams and the sill beams 101, which can disperse the energy generated by the collision, prevent or reduce the deformation of the cabin 100, and improve the strength and stability of the vehicle structure.

[0037] Furthermore, the two second reinforcing beam segments 2022 and the first reinforcing beam segment 2021 are integrally formed structural components, with no splicing or connecting parts between them. This not only improves the strength and precision of the structure but also reduces the number of parts and simplifies the production process, thereby reducing the manufacturing cost and weight of the vehicle.

[0038] Therefore, by setting the first reinforcing beam segment 2021 at the front end of the top cover assembly 201, and connecting the upper ends of the two second reinforcing beam segments 2022 to the left and right ends of the first reinforcing beam segment 2021 respectively, and the three reinforcing beam segments being integrally formed structural components, not only can the strength and stability of the cockpit 100 structure be improved, but the number of parts can also be reduced, the manufacturing process simplified, and the manufacturing cost reduced.

[0039] In some examples of this utility model, the overall structure of the reinforcing beam is presented as a U-shaped structure.

[0040] Combination Figure 1, Figure 3 and Figure 4 As shown, an arc-shaped transition beam segment 2023 is provided between the first reinforcing beam segment 2021 and the second reinforcing beam segment 2022. Specifically, by providing the arc-shaped transition beam segment 2023 between the first reinforcing beam segment 2021 and the second reinforcing beam segment 2022, not only can the force be transmitted more evenly between the first reinforcing beam segment 2021 and the second reinforcing beam segment 2022, thus avoiding stress concentration at the connection point and reducing the risk of breakage or damage at the connection point, but it can also absorb some of the collision energy during a vehicle collision, thereby improving the stability and safety of the vehicle structure.

[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, the top cover assembly 201 includes an upper top cover plate 2011 and a lower top cover plate 2012. The upper top cover plate 2011 is positioned above and connected to the lower top cover plate 2012. A first reinforcing beam segment 2021 is positioned between the upper top cover plate 2011 and the lower top cover plate 2012, with the front ends of the upper top cover plate 2011 and the lower top cover plate 2012 enclosing the first reinforcing beam segment 2021. Specifically, by positioning the upper top cover plate 2011 above and connecting it to the lower top cover plate 2012, a composite structure is formed, enhancing the strength and load-bearing capacity of the top cover assembly 201 and enabling it to better resist deformation. Furthermore, the first reinforcing beam segment 2021 is disposed between the upper roof plate 2011 and the lower roof plate 2012, and the front ends of the upper roof plate 2011 and the lower roof plate 2012 wrap around the first reinforcing beam segment 2021. This not only further enhances the strength of the roof assembly 201, but also makes the connection between the roof assembly 201 and the windshield assembly 202 more stable, thereby improving the strength and stability of the overall vehicle structure.

[0042] Combination Figure 1 , Figure 3 and Figure 4As shown, the windshield assembly 202 includes a first outer panel 2024, which is connected between the front end of the roof assembly 201 and the front end of the sill beam 101. The first outer panel 2024 covers the side of the second reinforcing beam segment 2022 away from the first reinforcing beam segment 2021 in the left-right direction and the upper side of the second reinforcing beam segment 2022. The first outer panel 2024 is connected and fixed to the second reinforcing beam segment 2022. Specifically, by connecting the first outer panel 2024 between the front end of the top cover assembly 201 and the front end of the sill beam 101, and covering the side of the second reinforcing beam segment 2022 away from the first reinforcing beam segment 2021 in the left-right direction and the upper side of the second reinforcing beam segment 2022, the first outer panel 2024 and the second reinforcing beam segment 2022 are connected and fixed. This not only improves the connection strength between the top cover assembly 201 and the sill beam 101, but also allows the second reinforcing beam segment 2022 to provide further support and reinforcement for the first outer panel 2024. The second reinforcing beam segment 2022 can absorb and disperse some of the force transmitted to the first outer panel 2024, effectively preventing the first outer panel 2024 from deforming. At the same time, the first outer panel 2024 can also protect the second reinforcing beam segment 2022, avoiding wear or deformation of the second reinforcing beam segment 2022. Furthermore, it can improve the load-bearing capacity and deformation resistance of the overall structure of the cabin 100.

[0043] Combination Figure 1 , Figure 3 and Figure 4 As shown, the windshield assembly 202 includes a second outer panel 2025, which extends in the left-right direction and covers the upper side of the front bulkhead 102. The second outer panel 2025 is connected to the front ends of the two second reinforcing beam segments 2022, the front ends of the two sill beams 101, and the upper side of the front bulkhead 102. Specifically, by extending the second outer panel 2025 in the left-right direction and covering the upper side of the front bulkhead 102, and connecting the second outer panel 2025 to the front ends of the two second reinforcing beam segments 2022, the front ends of the two sill beams 101, and the upper side of the front bulkhead 102, the strength of the upper side of the outer panel is improved, providing protection for the outer panel. Furthermore, the connection strength between the front bulkhead 102 and the sill beams 101 and the two second reinforcing beam segments 2022 is enhanced, preventing loosening or breakage at the connection points. This further strengthens the structure of the cabin 100 and improves its strength and stability.

[0044] Combination Figure 1 , Figure 3 and Figure 4As shown, a reinforcing cavity is provided at the upper end of the front bulkhead 102, extending in the left-right direction. Specifically, by providing a reinforcing cavity at the upper end of the front bulkhead 102, the load-bearing capacity of the upper area of ​​the front bulkhead 102 can be improved to withstand some of the impact forces caused by engine vibration or road bumps during vehicle operation. Furthermore, it can disperse and absorb the energy generated by the collision when the vehicle collides, thereby improving the strength and rigidity of the front bulkhead 102 structure and enhancing the stability and safety of the vehicle.

[0045] Combination Figure 1 , Figure 3 and Figure 4 As shown, the lower end of the second reinforcing beam segment 2022 is provided with a first overlapping portion 30, and the sill beam 101 is provided with a second overlapping portion 40. The first overlapping portion 30 and the second overlapping portion 40 overlap and cooperate. Specifically, by providing a first overlapping portion 30 at the lower end of the second reinforcing beam segment 2022 and a second overlapping portion 40 on the sill beam 101, and making the first overlapping portion 30 and the second overlapping portion 40 overlap and cooperate, the connection between the second reinforcing beam segment 2022 and the sill beam 101 can be made simple and direct, and the first overlapping portion 30 and the second overlapping portion 40 can be ensured to correspond in structure and position. It can also increase the contact area between the second reinforcing beam segment 2022 and the sill beam 101, making the connection between the second reinforcing beam segment 2022 and the sill beam 101 more stable. In addition, the overlapping structure can distribute the load, avoid stress concentration in the connection area leading to connection failure, and further improve the load-bearing capacity and stability of the overall structure of the cabin 100.

[0046] In some examples of this utility model, the area of ​​the overlapping region of the first overlapping part 30 and the second overlapping part 40 can be further increased, thereby making the connection between the reinforcing beam and the sill beam 101 more stable, making the reinforcing beam structure more stable, and further improving the stability of the cabin 100 structure.

[0047] Combination Figure 2 , Figure 3 and Figure 4As shown, the sill beam 101 includes an A-pillar portion 1011, a sill beam portion 1012, and a B-pillar portion. The A-pillar portion 1011 and the B-pillar portion are respectively located at the front and rear ends of the sill beam portion 1012. The A-pillar portion 1011, the B-pillar portion, and the sill beam portion 1012 are integrally formed structural components. The lower end of the second reinforcing beam segment 2022 is connected and fixed to the A-pillar portion 1011. Specifically, by setting the A-pillar portion 1011 and the B-pillar portion at the front and rear ends of the sill beam portion 1012, the A-pillar portion 1011, the sill beam portion 1012, and the B-pillar portion together constitute the overall structure of the sill beam 101. This ensures the strength of the vehicle structure. When the vehicle is involved in a collision, the sill beam 101 can disperse and absorb some or all of the energy, avoiding or reducing the deformation of the vehicle structure and protecting the safety of passengers inside the vehicle.

[0048] Furthermore, the A-pillar 1011, B-pillar, and sill beam 1012 are integrally formed structural components, with no splicing or connecting parts between them. This not only further enhances the structural strength of the sill beam 101 but also reduces the number of parts, thereby reducing mold development, simplifying the production process, improving the vehicle body's integration and structural strength, and lowering vehicle production costs and cycle time.

[0049] In addition, the lower end of the second reinforcing beam segment 2022 is connected and fixed to the A-column portion 1011. Specifically, the lower end of the second reinforcing beam segment 2022 is provided with a first overlapping portion 30, and the A-column portion 1011 of the threshold beam 101 is provided with a second overlapping portion 40. By connecting and fixing the first overlapping portion 30 and the second overlapping portion 40, the lower end of the second reinforcing beam segment 2022 is connected and fixed to the A-column portion 1011.

[0050] In some examples of this utility model, the first overlapping portion 30 and the second overlapping portion 40 are bonded together. Specifically, by bonding the first overlapping portion 30 and the second overlapping portion 40 together, the adhesive can form a firm and tight fit between the overlapping surfaces. This not only improves the stability of the connection between the first overlapping portion 30 and the second overlapping portion 40, but also makes the force distributed more evenly in the overlapping area between the first overlapping portion 30 and the second overlapping portion 40, thereby improving the rigidity of the overlapping area. Furthermore, it can improve the rigidity and stability of the cockpit 100 structure.

[0051] In some examples of this utility model, combined with Figure 4As shown, a first through hole 301 is provided on the first overlapping portion 30, and a second through hole 401 is provided on the second overlapping portion 40. The first through hole 301 and the second through hole 401 correspond to each other and are connected and fixed by fasteners. Specifically, the first overlapping portion 30 is provided with a first through hole 301, and the second overlapping portion 40 is provided with a second through hole 401. The first through hole 301 and the second through hole 401 correspond in structure and position, and the first through hole 301 and the second through hole 401 are sequentially passed through by fasteners, thereby connecting and fixing the first overlapping portion 30 and the second overlapping portion 40. This not only improves the stability of the connection and fixation between the first overlapping portion 30 and the second overlapping portion 40 and enhances the load-bearing capacity of the cabin 100 structure, but also facilitates the disassembly of the first overlapping portion 30 and the second overlapping portion 40, making it convenient for subsequent vehicle maintenance or repair needs.

[0052] In some examples of this utility model, the connection between the first overlapping part 30 and the second overlapping part 40 can also be achieved by a combination of adhesive bonding and fastener connection, which further enhances the stability of the connection between the lower end of the second reinforcing beam segment 2022 and the A-column part 1011.

[0053] Combination Figure 2 , Figure 3 and Figure 4 As shown, the sill beam 101 also includes a front longitudinal beam rear section connecting part 1013, an outer wheel cover part 1014, and a torsion box part 1015. The front longitudinal beam rear section connecting part 1013 is located on the front side of the A-pillar part 1011 and is suitable for connecting the rear section of the front longitudinal beam in the front engine compartment of the vehicle. The outer wheel cover part 1014 and the torsion box part 1015 are located on the front longitudinal beam rear section connecting part 1013. The A-pillar part 1011, the sill beam part 1012, the B-pillar part, the front longitudinal beam rear section connecting part 1013, the outer wheel cover part 1014, and the torsion box part 1015 are integrally formed structural components. The area between the A-pillar part 1011 and the front longitudinal beam rear section connecting part 1013 is at least partially connected and fixed to the lower end of the second reinforcing beam section 2022. Specifically, by setting the rear section connecting part 1013 of the front longitudinal beam on the front side of the A-pillar 1011 and suitable for connecting the rear section of the front longitudinal beam to the front engine compartment of the vehicle, and setting the outer wheel cover part 1014 and the torque box part 1015 on the rear section connecting part 1013 of the front longitudinal beam, the rear section connecting part 1013 of the front longitudinal beam can ensure the connection between the front longitudinal beam and the cabin 100, so that the front longitudinal beam and the cabin 100 together constitute the basic frame of the vehicle. The outer wheel cover part has a certain energy absorption function, which can protect the cabin 100 and the wheels. The torque box part 1015 can withstand and transmit the torque generated during the vehicle's operation, which can improve the strength of the vehicle structure.

[0054] Furthermore, the A-pillar 1011, sill beam 1012, B-pillar, rear section connection of the front longitudinal beam 1013, outer wheel arch 1014, and torsion box 1015 are integrally formed structural components. The area between the A-pillar 1011 and the rear section connection of the front longitudinal beam 1013 is at least partially connected and fixed to the lower end of the second reinforcing beam section 2022. This not only further enhances the strength of the sill beam 101 structure and reduces its manufacturing cost, but also further improves the stability of the connection between the sill beam 101 and the second reinforcing beam section 2022, providing better support for the windshield assembly 202, thereby enhancing the overall structural strength and stability of the cabin 100.

[0055] The vehicle according to this utility model can mainly include: the aforementioned cockpit 100. Specifically, since the cockpit 100 has higher structural strength and better stability, applying the cockpit 100 to a vehicle can improve the strength and stability of the vehicle structure, reduce the manufacturing cost of the vehicle, and reduce the weight of the vehicle.
