Description

Technical Field

[0001] The utility model is applied to the field of bus driver protection, and particularly relates to a frontal collision protection frame for bus drivers. Background Art

[0002] Driver safety has always been a major concern in existing bus designs. Effectively protecting the driver from injury in head-on collisions, in particular, has become a pressing technical challenge. While traditional driver protection devices, such as seatbelts and airbags, can mitigate driver injuries to a certain extent, they remain insufficient in high-intensity collisions.

[0003] Currently, buses are generally designed with a flat-head structure to meet the needs of their large passenger capacity. However, due to the low operating speed of buses and the lack of mandatory requirements for frontal collisions in domestic vehicle certification regulations, vehicle manufacturers generally do not design the front of the vehicle to strengthen its anti-frontal collision structure. In front of the driver's seat, there is generally a steering column bracket extending from the driver's section of the chassis frame. When subjected to a frontal collision, this structure is prone to plastic deformation of the instrument panel and steering wheel backwards, squeezing the driver's living space. Especially in the case of a bus rear-ending a truck or van, due to the excessive stress concentration at the connection between the steering column bracket and the driver's section of the chassis frame, the steering column bracket may break at the connection point with the chassis, and the instrument panel and steering wheel will significantly squeeze the driver's living space, further endangering the driver's life.

[0004] Therefore, based on the above problems, if a bus driver's front collision protection frame can be designed, which first increases the longitudinal structural strength and distributes the energy during a frontal collision to the floor frame at the driver's position, and can effectively reduce the relative displacement between the square coil column bracket and the driver's seat bracket, and secondly, a crumple space is reserved between the driver's seat bracket and the rear tube, so that when subjected to a certain degree of frontal collision, the driver's seat will move backward to provide the driver with more survival space, then the above problems can be well solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and design a frontal collision protection frame for the driver of a bus. The protection frame firstly increases the longitudinal structural strength and distributes the energy during a frontal collision to the floor frame at the driver's position, and can effectively reduce the relative displacement between the square coil column bracket and the driver's seat bracket. Secondly, the protection frame reserves a collapse space between the driver's seat bracket and the rear tube.

[0024] like Figure 1 and Figure 2As shown, in this embodiment, the present invention is connected to the chassis driving section frame 2. The crash protection frame 1 is formed by welding a steering column support bracket 10 and a driver's seat support assembly 11. The steering column support bracket 10 is provided with a steering column mounting bracket 12, a plurality of outer reinforcement plates 13, and a plurality of inner reinforcement plates 14. The steering column mounting bracket 12, the plurality of outer reinforcement plates 13, and the plurality of inner reinforcement plates 14 are fixedly coupled to the steering column support bracket 10 by welding. It can be seen that when the vehicle collides head-on with an obstacle, the crash protection frame 1 plays a role in protecting the driver. The steering column support bracket 10 supports and fixes the steering column mounting bracket 12, the plurality of outer reinforcement plates 13, and the plurality of inner reinforcement plates 14, thereby increasing the structural strength of the crash protection frame 1. When the vehicle collides head-on with an obstacle, the driver's seat support assembly 11 acts to move the driver backward, preventing the driver from colliding with the steering column support bracket 10 and other components, causing personal injury.

[0025] like Figure 3 As shown, in this embodiment, the steering column support bracket 10 includes a pair of main columns 100, a pair of chassis frame connecting columns 101, a pair of upper diagonal bracing beams 102, a pair of lower diagonal bracing beams 103, a pair of front support beams 104 and a number of connecting cross beams 105. One end of the main columns 100, the chassis frame connecting columns 101 and the front support beam 104 are all connected and cooperated with the chassis driving section frame 2, the two ends of the upper diagonal bracing beam 102 are respectively connected and cooperated with the main columns 100 and the front support beam 104, and the two ends of the lower diagonal bracing beam 103 are respectively connected and cooperated with the chassis frame connecting columns 101 and the front support beam 104. A number of the connecting cross beams 105 are respectively arranged between the pair of main columns 100 and the pair of front support beams 104, and connected and cooperated with the pair of main columns 100 and the pair of front support beams 104. It can be seen that the main column 100 serves to connect the upper diagonal bracing beam 102 and the chassis driving section frame 2, the chassis frame connecting column 101 serves to connect the front support beam 104 and the lower diagonal bracing beam 103, and the front support beam 104 serves to guide and disperse the frontal impact force to the upper and lower main cross beams of the chassis driver section frame 2 and other contacting structures.

[0026] like Figure 4As shown, in this embodiment, the driver seat support assembly 11 includes a pair of support main beams 110, a crush support 111, a support cross beam 112, a pair of lower support beams 113 and a seat mounting bracket 114. The middle portion of the support cross beam 112 is fixedly matched to the pair of support main beams 110, and the two ends of the support cross beam 112 are respectively connected to the chassis driving section frame 2. One end of the support main beam 110 is connected to the middle portion of the crush support 111, and the two ends of the crush support 111 are respectively connected to the chassis driving section frame 2. They are respectively connected and cooperated with the chassis driving section frame 2, the other end of the bracket main beam 110 is connected and cooperated with the chassis driving section frame 2, one end of the lower support beam 113 is inclined and connected and cooperated with the middle part of the bracket main beam 110, and the other end of the lower support beam 113 is connected and cooperated with the chassis driving section frame 2, the seat mounting bracket 114 is arranged between the collapse bracket 111 and the bracket cross beam 112, and the seat mounting bracket 114 is respectively fixed and cooperated on a pair of the bracket main beams 110. It can be seen that the bracket main beam 110 serves to connect with the lower support beam 113, the bracket cross beam 112 and the collapse bracket 111. At the same time, the bracket main beam 110 also connects and cooperates with the chassis driving section frame 2. The bracket main beam 110 and the bracket cross beam 112 support and fix the seat mounting bracket 114. The lower support beam 113 is respectively connected with the chassis driving section frame 2 and the bracket main beam 110 to form a triangular structure, which greatly improves the vertical support force of the driver seat bracket assembly 11.

[0027] like Figure 3 As shown, in this embodiment, the steering column support bracket 10 is formed by welding together a plurality of square tubes. The front support beam 104 forms two upper and lower triangular structures with the main column 100, the upper diagonal bracing beam 102, and the diagonal bracing beam 103. Thus, the welding of a plurality of square tubes to form the steering column support bracket 10 not only stabilizes the steering column support bracket 10 but also reduces production costs. The front support beam 104 forms two upper and lower triangular structures with the main column 100, the upper diagonal bracing beam 102, and the diagonal bracing beam 103, thereby enhancing the front structural strength of the steering column support bracket 10. When the vehicle collides head-on with an obstacle, the impact surface is higher than the pedal surface of the chassis driver's section frame 2 but not higher than the steering column mounting bracket 10. This allows the frontal impact force to be directed and dispersed to the upper and lower main crossbeams of the chassis driver's section frame 2 and other contacting structures, thereby reducing the risk of driver injury.

[0028] like Figures 8 to 10As shown, in this embodiment, the collapse bracket 111 is provided with collapse inducing notches 115 on the left and right ends near the middle, the bracket cross beam 112 is provided with a first cross beam inducing notch 116 at the connection with a pair of the bracket main beams 110 respectively, and the bracket cross beam 112 is provided with a second cross beam inducing notch 117 at the connection with the chassis driving section skeleton 2 on the left and right ends. The openings of the collapse inducing notch 115 and the second cross beam inducing notch 117 are away from the steering column support bracket 10, and the opening of the first cross beam inducing notch is close to the steering column support bracket 10. It can be seen that because the bracket main beam 110 is made of high-strength steel, it is not easy to undergo serious plastic deformation when subjected to the compressive force generated by a head-on collision. When the cockpit is hit head-on, the steering column mounting bracket 10 will be squeezed and deformed backward relative to the chassis driver section frame 2. The bracket cross beam 112 of the driver's seat utilizes the characteristics of the collapse inducing notch 115, the first cross beam inducing notch 116 and the second cross beam inducing notch 117 that are easy to crack and undergo plastic deformation, so that the bracket cross beam 112 of the driver's seat also moves backward, thereby providing more living space for the driver.

[0029] like Figure 5 As shown, in this embodiment, the steering column mounting bracket 12 is provided with a plurality of bracket plug welding holes 120 and a plurality of mounting connection holes 121. The steering column mounting bracket 12 is welded with the main column 100 through the plurality of bracket plug welding holes 120. A plurality of reinforcing ribs 122 are also provided in the steering column mounting bracket 12. It can be seen that the steering column mounting bracket 12 supports and fixes the several bracket plug welding holes 120, the several mounting connection holes 121 and the several reinforcing ribs 122. The mounting connection holes 121 connect the steering column mounting bracket 12 with the steering column element, so that the steering column mounting bracket 12 can be fixed to the steering column element by fasteners. The several bracket plug welding holes 120 weld the steering column mounting bracket 12 to the main column 100 and the upper diagonal bracing beam 102. The steering column mounting bracket 12 improves the positive structural strength of the main column 100 and the upper diagonal bracing beam 102. The several reinforcing ribs 122 improve the structural strength of the mounting surface of the steering column mounting bracket 12 with other components, thereby effectively improving the operational sensitivity of the steering wheel.

[0030] like Figure 6As shown, in this embodiment, the outer reinforcing plate 13 is provided with a plurality of first plug welding holes 130, and the outer reinforcing plate 13 is fixedly matched with the upper diagonal bracing beam 102, the lower diagonal bracing beam 103, and the front support beam 104 through the plurality of first plug welding holes 130. It can be seen that the outer reinforcing plate 13 supports and fixes the plurality of first plug welding holes 130, and the plurality of first plug welding holes 130 serve to weld and fix the outer reinforcing plate 13 to the upper diagonal bracing beam 102, the lower diagonal bracing beam 103, and the front support beam 104, and the outer reinforcing plate 13 serves to strengthen the structural strength of the overlap between the upper diagonal bracing beam 102, the lower diagonal bracing beam 103, and the front support beam 104.

[0031] like Figure 7 As shown, in this embodiment, the inner reinforcing plate 14 is provided with a plurality of second plug welding holes 140, and the inner reinforcing plate 14 is fixedly engaged with the main pillar 100 and the front support beam 104 through the plurality of second plug welding holes 140. Thus, it can be seen that the inner reinforcing plate 14 supports and fixes the plurality of second plug welding holes 140, and the plurality of second plug welding holes 140 serve to weld and fix the inner reinforcing plate 14 to the main pillar 100 and the front support beam 104. The inner reinforcing plate 14 serves to strengthen the structural strength of the overlap between the main pillar 100, the front support beam 104, and the crossbeam on the chassis driving section frame 2.

[0032] In this embodiment, the working principle of the utility model is as follows:

[0033] like Figures 1 to 10 As shown, the collision protection frame 1 is connected and matched with the chassis driving section frame 2. When the vehicle collides head-on with an obstacle, the steering column support bracket 10 resists the impact force and guides and disperses the frontal impact force to the upper and lower main cross beams of the chassis driver section frame and other contacting structures. At the same time, the driver's seat bracket assembly is squeezed and deformed, causing the bracket main beam 110 on the driver's seat to also move backward, giving the driver more living space.

[0034] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
