Frame assembly and vehicle having the same

Abstract

This invention discloses a chassis assembly and a vehicle having the same, belonging to the field of wheel crumple zone energy absorption technology. The chassis assembly includes a wheel, a frame, and a crash unit assembly. An A-pillar is connected to the frame, and the wheel is connected to the frame. The crash unit assembly is located on the A-pillar and on one side of the wheel in the horizontal direction. The free end of the crash unit assembly is positioned opposite the wheel, and the crash unit assembly is constructed to destroy the wheel. When the chassis assembly collides, the wheel contacts the free end of the crash unit assembly, causing the wheel structure to collapse and absorb energy. Because the crash unit assembly is located on one side of the wheel, it can break the wheel structure upon impact, thus destroying the wheel structure. The destroyed wheel structure can absorb the impact, reducing the impact force on the cab and improving driving safety.

Description

Technical Field

[0001] This invention relates to the field of wheel collapse energy absorption technology, and in particular to a frame assembly and a vehicle having the same. Background Technology

[0002] In existing technologies, during vehicle operation, when a frontal impact occurs, the impact is typically directed at the vehicle's front end to deform the front structure. This deformation process absorbs the impact, reducing its impact on the cab. However, in actual impacts, due to the high rigidity of the wheel hubs, the impact is more likely to be transmitted than absorbed, allowing it to reach the cab and affect its structural performance, thus jeopardizing driver safety. Current technologies typically employ cab reinforcement, but this method not only increases production costs but also fails to provide sufficient protection, still posing safety risks. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a frame assembly in which a break-through part is disposed opposite to the wheel. In the event of an impact, the break-through part can destroy the structure of the wheel so that the wheel can collapse and absorb energy, thereby absorbing the impact force and preventing the impact force from being transmitted to the cab, thus improving the safety of the user in the cab.

[0004] Another object of the present invention is to provide a vehicle having a frame assembly as shown above.

[0005] According to an embodiment of the present invention, a vehicle frame assembly includes: a wheel, a frame, and a crashing device assembly. An A-pillar is connected to the frame, and the wheel is connected to the frame. The crashing device assembly is disposed on the A-pillar and on one side of the wheel in a horizontal direction. The free end of the crashing device assembly is disposed opposite to the wheel, and the crashing device assembly is configured to destroy the structure of the wheel. When the vehicle frame assembly collides, the wheel contacts the free end of the crashing device assembly, and the structure of the wheel is destroyed and collapses to absorb energy.

[0006] According to the vehicle frame assembly of the present invention, since a knockdown component is provided on one side of the wheel, the knockdown component can knock down the wheel structure in the event of an impact, thereby destroying the wheel structure. The destroyed wheel structure can absorb the impact, thereby reducing the impact force on the cab and improving the driving safety of the cab.

[0007] In some embodiments, the wheel includes a hub and a tire, the tire being disposed on the outside of the hub; the hacking assembly includes a connecting portion and a hacking body, the connecting portion being connected to the A-pillar; the hacking body being connected to the connecting portion, and the free end of the hacking body having a hacking part facing the wheel and destroying the wheel structure upon impact; wherein, when the hacking assembly contacts the wheel and destroys the wheel structure, the hacking part first destroys the tire structure and then destroys the hub structure.

[0008] In some embodiments, at least a portion of the cross-section of the cracking part is triangular, and the angle of the top cross-section of the cracking part is A, wherein the angle A satisfies the relationship: A≤90°; and / or, the output end of the cracking part is provided with a transverse blade, which extends along the longitudinal direction of the wheel.

[0009] In some embodiments, at least a portion of the cross-sectional shape of the cracking part is configured as a triangle, with a top surface blade at the top of the cracking part, thereby giving the cracking part higher structural strength to crack the wheel, and enabling the frame assembly to improve the safety of the cab.

[0010] In some embodiments, a transverse blade is provided at the output end of the cracking unit, so that the cracking unit can crack the tire of the wheel more quickly when in use, and can destroy the wheel hub more efficiently, thereby better absorbing the impact of the front of the vehicle and making the vehicle safer to drive.

[0011] In some embodiments, the longitudinal width of the cracking part is greater than the longitudinal length of the transverse cutting edge.

[0012] In some embodiments, the longitudinal width of the cracking part is greater than the longitudinal length of the transverse blade, so that the impact force of the vehicle during the collision can be absorbed by the damaged wheel, making the vehicle's cab safer during the collision.

[0013] In some embodiments, there are two connecting portions, and the two connecting portions are spaced apart on the cracker body in the longitudinal direction.

[0014] In some embodiments, by providing two connecting parts on the body of the cracker, the frame assembly can be connected to the frame through the two connecting parts during the installation process, thereby improving the reliability of the frame assembly during the installation process. This allows the frame assembly to have higher structural performance to crack the wheel structure, enabling the wheel to absorb and decompose the impact.

[0015] In some embodiments, a weight-reducing portion is provided between the two connecting portions and the cracking portion.

[0016] In some embodiments, a weight-reducing section is provided between the two connecting parts and the breaking part to save on the production materials of the frame assembly, thereby reducing the production cost of the frame assembly and improving the applicability of the frame assembly.

[0017] In some embodiments, each of the connecting portions is welded to the vehicle frame.

[0018] In some embodiments, the frame assembly can be connected to the frame by welding to make the frame assembly's placement on the frame more reliable. This allows the frame assembly to contact the wheels as designed and drive the structural collapse and energy absorption of the wheels, thus making the cab's structural layout more reliable and improving cab safety. In other specific embodiments, the connection is adapted to be welded to the frame using a double-shielded welding method to make the connection between the connection and the frame more reliable, thereby improving the performance of the frame assembly.

[0019] In some embodiments, the device further includes a fixing bolt, wherein the connecting portion has a connecting hole, and the fixing bolt passes through the connecting hole and is fixedly connected to the vehicle frame.

[0020] In some embodiments, to make the connection between the frame assembly and the frame more reliable, fixing bolts are used to connect the connecting part to the frame, so that the frame assembly can be reliably installed on the frame, thereby enabling the frame assembly to have high performance in the event of a collision to meet the needs of use and ensure the safety of the cab.

[0021] In some embodiments, the frame assembly is a one-piece cast metal part.

[0022] In some embodiments, by configuring the frame assembly as a one-piece structural component, the production steps of the frame assembly are reduced, the production process is simplified, the connection strength between the crack and the connecting part is improved, and the structural strength of the frame assembly is increased.

[0023] A vehicle according to an embodiment of the present invention includes: a frame assembly as described above.

[0024] According to an embodiment of the present invention, the vehicle is equipped with a knockdown assembly on one side of the wheel, which can knock down the wheel structure in the event of an impact, thereby destroying the wheel structure. The destroyed wheel structure can absorb the impact, thereby reducing the impact force on the cab and improving the driving safety of the cab.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Connecting part 100, weight reduction part 101, The main body of the hacker is 200, the hacking part is 210, and the horizontal blade is 211. Vehicle 20. Detailed Implementation

[0027] 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.

[0028] The following is for reference. Figures 1-3 A frame assembly 10 according to an embodiment of the present invention is described, including: wheels 12, a frame 11, and a hacker assembly 13.

[0029] Specifically, an A-pillar 14 is connected to the frame 1, and a wheel 12 is connected to the frame 11. A hacking component 13 is located on the A-pillar 14 and is located on one side of the wheel 12 in the horizontal direction. The free end of the hacking component 13 is positioned opposite to the wheel 12, and the hacking component 13 is configured to destroy the wheel 12. When the frame assembly 10 collides, the wheel 12 contacts the free end of the hacking component 13, and the structure of the wheel 12 is destroyed and collapses to absorb energy.

[0030] It should be noted that during the movement of vehicle 20, when a frontal impact occurs, the impact is intended to act on the front of vehicle 20 to drive the front structure to deform. During deformation, the impact is absorbed to reduce the impact on the cab. However, in actual impact, because the wheel hub of wheel 12 has a high rigidity structure, it is more suitable for transmitting the impact than absorbing it, resulting in a greater impact on the cab.

[0031] Therefore, this application provides a chassis assembly 10, on which a hacking component 13 is provided. Since the hacking component 13 is located on one side of the wheel 12, when the vehicle 20 is driving normally, there is a gap between the wheel 12 and the hacking component 13, and the hacking component 13 does not contact the wheel 12, so that the hacking component 13 will not affect the normal driving of the vehicle 20. When the front of the vehicle 20 is impacted, the impact force is suitable to act on the chassis assembly 10 to drive the wheel 12 to translate and contact the hacking component 13. Then the hacking component 13 is suitable to hack the structure of the wheel 12 to destroy the rigid structure of the wheel 12, so that the wheel 12 can absorb the impact force, thereby reducing or even eliminating the impact force on the cab, so as to improve the safety of the cab during the impact.

[0032] According to an embodiment of the present invention, the frame assembly 10 has a knockdown component 13 provided on one side of the wheel 12. When an impact occurs, the wheel 12 is adapted to contact the knockdown component 13 so that the knockdown component 13 can destroy the rigid structure of the wheel 12. The destroyed wheel 12 can absorb the impact, thereby improving the safety of the cab and thus improving the safety of the vehicle 20.

[0033] In some embodiments, the wheel 12 includes a hub 16 and a tire 15, with the tire 15 covering the outside of the hub 16; the hacking assembly 13 includes a connecting portion 100 and a hacking body 200, with the connecting portion 100 connected to the A-pillar 14; the hacking body 200 is connected to the connecting portion 100, and the free end of the hacking body 200 is provided with a hacking portion 210, which faces the wheel 12 and destroys the structure of the wheel 12 upon impact; wherein, when the hacking assembly 13 contacts the wheel 12 and destroys the structure of the wheel 12, the hacking portion 210 first destroys the tire 15 structure and then destroys the hub 16 structure.

[0034] It should be noted that the wheel 12 is adapted to include a hub 16 and a tire 15. The tire 15 is adapted to be fitted onto the outside of the hub 16. When the hacking device assembly 13 hacks the wheel 12, it is adapted to hack the tire 15 first. Since the tire 15 is adapted to be made of rubber, the hacking device assembly 13 can quickly destroy the structure of the tire 15, thereby allowing the hacking device assembly 13 to quickly break the tire 15 and then contact the hub 16. The hub 16 generally adopts a rigid structure to make the hub 16 suitable for transmitting the impact force. In this application, after the hacking device assembly 13 breaks the tire 15, it is adapted to contact the hub 16 and hack the hub 16. When the structure of the hub 16 is destroyed, the hub 16 can collapse. During the collapse process, it is adapted to deform to absorb and decompose the impact force, thereby reducing or even avoiding the impact force being transmitted to the cab and affecting the safety of the cab. In this way, the driving safety of the cab is improved.

[0035] Specifically, the hacking device assembly 13 is adapted to include a connecting part 100 and a hacking device body 200. The connecting part 100 is adapted to be connected to the A-pillar 14, so that the hacking device body 200 connected to the connecting part 100 can be positioned on one side in the length direction of the wheel, thereby achieving a relative arrangement between the hacking device body 200 and the wheel 12. A hacking part 210 is provided on the hacking device body 200, so that the hacking part 210 can be positioned relative to the wheel 12. For example, in the event of an impact, the hacking part 210 can first hack the tire 15, and then contact the wheel hub 16 and destroy the structure of the wheel hub 16, so that the structure of the wheel hub 16 can collapse and absorb the impact, thereby reducing the impact force acting on the passenger compartment.

[0036] According to the vehicle frame assembly 10 of the present invention, since a knock-down component 13 is provided on one side of the wheel 12, the knock-down component 13 can knock down the structure of the wheel 12 when an impact occurs, so that the structure of the wheel 12 is destroyed. The destroyed wheel 12 structure can absorb the impact, thereby reducing the impact force on the cab and improving the driving safety of the cab.

[0037] Meanwhile, in other embodiments, the connecting part 100 is adapted to be installed on the frame 11 as needed. Its specific position can be adjusted as needed, as long as it is ensured that the cracking part 210 of the cracking device assembly 13 can contact the wheel 12 in the event of an impact, so that the cracking part 210 can destroy the structure of the wheel 12. After the rigid structure of the wheel 12 is destroyed, the structure of the wheel 12 will collapse under the pressure. During the collapse process, the impact will be absorbed and decomposed to reduce the impact on the driver's cab and the user inside the driver's cab when the impact is transmitted to the driver's cab, thereby improving the safety of the user when driving the vehicle.

[0038] In some embodiments, at least a portion of the cross-section of the cracking part 210 is triangular, and the angle of the top cross-section of the cracking part 210 is A, wherein the angle A satisfies the relationship: A≤90°.

[0039] Understandably, the cross-sectional shape of at least a portion of the cracking unit 210 is constructed as a triangle, with a top-faced blade at the top. This gives the cracking unit 210 higher structural strength to crack the wheel 12, thereby improving the safety of the cab of the frame assembly 10. Furthermore, to enhance the performance of the cracking unit 210, its top cross-sectional angle is relatively low, making it sharper and faster at cracking the structure of the wheel 12. This allows the wheel 12 to better absorb impact, further improving the safety of the vehicle 20 cab. Moreover, to achieve higher cracking performance, the top cross-sectional angle of the cracking unit 210 should be set as low as possible; an excessively low angle would reduce the repeatability of the cracking device component 13. Therefore, the top cross-sectional angle of the cracking part 210 is set between 45° and 90° so that the setting of the cracking part 210 can take into account both structural strength for use and high sharpness for damaging the wheel 12 structure, so that the damaged wheel 12 can absorb and decompose the impact, thereby further improving driving safety.

[0040] In other embodiments, the structure of the cracking unit 210 can be configured with multiple blades arranged in parallel to improve the reliability of the cracking unit 210 when cracking the wheel 12. This allows the vehicle 20 to be more efficient and faster in cracking the wheel 12 structure through multiple blades when an impact occurs, so that the wheel 12 structure can be damaged and collapse more quickly. This allows the damaged wheel 12 to absorb and decompose the impact, thereby improving the driving safety of the vehicle 20.

[0041] In some embodiments, the output end of the cracking unit 210 is provided with a transverse blade 211, which extends along the longitudinal direction of the wheel 12. It is understood that the transverse blade 211 at the output end of the cracking unit 210 allows it to more quickly crack the tire 15 of the wheel 12 and to more efficiently damage the wheel hub, thereby better absorbing the impact force on the front of the vehicle 20 and improving the driving safety of the vehicle 20.

[0042] Of course, this application is not limited to this. In some other embodiments, the extension direction of the cracking unit 210 can be arranged parallel to the rolling direction of the wheel 12. In this way, when the vehicle 20 is impacted, the wheel 12 is also suitable for rotating. The rotating wheel 12 will come into contact with the cracking component 13 more quickly and crack the wheel 12, so that the cracking component 13 can work more efficiently during use and crack the wheel 12 structure more quickly. After cracking, the wheel 12 structure can absorb and decompose the impact more efficiently, thereby improving the driving safety of the vehicle 20.

[0043] Furthermore, in some other embodiments, the extension direction of the cracking unit 210 can be tilted according to the structure of the vehicle 20, so that the cracking unit 210 can effectively crack the wheel 12 during operation, while also having high structural strength to meet the usage requirements of the cracking device component 13. This allows the vehicle 20 to effectively damage the structure of the wheel 12 when an impact occurs, so that the wheel 12 can absorb and decompose the impact as designed, thereby improving the driving safety of the cab.

[0044] In some embodiments, the longitudinal width of the cracking part 210 is greater than the longitudinal length of the wheel 12. It should be noted that the longitudinal width of the cracking part 210 is suitable to be greater than the longitudinal length of the transverse blade 211, so that the structure of the cracking part 210 can cover the width of the wheel 12 of the vehicle 20. This allows the cracking part 210 to contact the wheel 12 and crack its structure according to design during various operating conditions, such as impacts during driving or turning, enabling the wheel 12 to crumple and absorb the impact, thereby improving the driving safety of the cab. In other words, by making the longitudinal width of the cracking part 210 greater than the longitudinal width of the wheel 12, the wheel 12 of the vehicle 20 can always crack against the cracking part 210 at the front end of the frame assembly 10 when rotating, allowing the impact force of the vehicle 20 during an impact to be absorbed by the damaged wheel 12, thus providing higher safety for the cab of the vehicle 20 during an impact. Of course, this application is not limited to this. The lateral length of the cracking part 210 is also suitable to be less than the longitudinal length of the wheel 12, so as to ensure that the cracking part 210 can contact the wheel and crack the structure of the wheel 12, so that the damaged wheel 12 can absorb the impact and improve the safety of the cab.

[0045] In other embodiments, the arrangement of the hacking unit 210 can be adjusted according to the design of the vehicle 20. For example, the longitudinal length of the hacking unit 210 can be set opposite to two-thirds of the longitudinal length of the wheel 12, or the longitudinal length of the hacking unit 210 can be set opposite to half the longitudinal length of the wheel 12. This allows the hacking unit 210 to be positioned opposite to the wheel 12 when the vehicle 20 is running in different states. This allows the wheel 12 to contact the hacking unit 13 as designed, and allows the hacking unit 13 to destroy the structure of the wheel 12 and collapse. This allows the wheel 12 to absorb and decompose the impact, reducing the impact effect on the cab and improving the safety of the cab.

[0046] In some embodiments, there are two connecting portions 100, and the two connecting portions 100 are spaced apart in the longitudinal direction on the hacking device body 200. It is understood that by providing two connecting portions 100 on the hacking device body 200, the frame assembly 10 can be connected to the frame 11 through the two connecting portions 100 during the installation process, thereby improving the reliability of the frame assembly 10 in the installation of the frame 11, and thus giving the frame assembly 10 higher structural performance to hack the wheel 12 structure, so that the wheel 12 can absorb and decompose the impact.

[0047] In other words, in some specific embodiments, it is suitable to arrange and connect the two connecting parts 100 to the frame 11 of the vehicle 20 in a laterally spaced manner, so as to make the connection between the connecting parts 100 and the frame 11 more reliable, so that the connecting parts 210 can abut against the frame 11 as designed, so that the wheels 12 can achieve more reliable connection, and so as to make the driving of the vehicle 20 safer. Of course, this application is not limited to this, and it is also suitable to construct the two connecting parts 100 on the frame 11 in a longitudinally spaced manner. The specific construction method can be adjusted according to the needs to ensure that they can be reliably arranged on the frame 11, which will not be elaborated here.

[0048] Furthermore, in some embodiments, it is suitable to provide a jammer assembly 13 on the frame assembly 10 and arrange the jammer assembly 13 on the frame 1 on the cab side, so that when an impact occurs on the cab side, the wheel 12 on the cab side can be destroyed in time, so that the impact can be decomposed and absorbed in time during the crumpling process, thereby reducing the impact force on the cab and thus reducing the impact on the driver, thereby reducing the impact on the driver and improving the driving safety of the vehicle.

[0049] In other embodiments, a hacking component 13 can be provided on both front wheels 12, so that when the vehicle is involved in a collision, both front wheels can be hacked by the hacking part 210 of the hacking component, so that the hacking component 13 can structurally destroy the two front wheels of the vehicle 20, thus destroying the structure of both wheels 12. Compared with installing the hacking component 13 on one side of the cab, setting two hacking components 13 can not only improve the reliability of the vehicle 20 in using the hacking component 13, but also ensure that the hacking component 13 can be used as designed to destroy the front wheel structure of the vehicle 20, so that the impact can trigger the wheels to collapse, thereby reducing the impact on the cab and decomposing and eliminating the impact on the cab, thus providing higher safety for the user 4 in the cab and improving the safety of vehicle use.

[0050] In some embodiments, a weight-reducing part 101 is provided between the two connecting parts 100 and the cracking part 210. It is understood that the weight-reducing part 101 is also provided between the two connecting parts 100 and the cracking part 210 to save production materials of the frame assembly 10, thereby reducing the production cost of the frame assembly 10 and improving the applicability of the frame assembly 10.

[0051] Furthermore, the weight reduction part 101 can be adapted to be built on one side of the connecting part 100, so that the structural arrangement of the hacker component 13 is simpler and more reliable, so that it can be arranged on the side of the vehicle 20 facing the center as designed, and at the same time, the production and construction cost of the hacker component 13 can be further reduced, so that the production cost of the chassis assembly 10 can be further reduced.

[0052] Of course, this application is not limited to this. Other weight-reducing parts 101 can also be provided on the hacking component 13 as needed, so that the hacking part 210 can maintain high structural strength while minimizing production costs, thereby further reducing the cost of the frame assembly 10. For example, other shapes of weight-reducing parts 101 can be constructed on the hacking component 13, including circular, square, and other shapes, to save production materials for the hacking component 13 and reduce production costs.

[0053] In some embodiments, each connecting part 100 is welded to the frame 11. That is, when the frame assembly 10 is connected to the frame 11, welding can be used to make the mounting of the frame assembly 10 on the frame 11 more reliable. This allows the frame assembly 10 to contact the wheels 12 as designed and drive the structural collapse and energy absorption of the wheels 12, thus making the cab structural arrangement more reliable and improving cab safety. In other specific embodiments, the connecting part 100 is adapted to be welded to the frame 11 using a double-shielded welding method to make the mounting between the connecting part 100 and the frame 11 more reliable, thereby improving the performance of the frame assembly 10.

[0054] In other embodiments, an overlap portion may be provided between the two connecting portions 100. The overlap portion is adapted to improve the connection reliability of the connecting portions 100, so as to improve the reliability of the hacking component on the frame 11. This allows the hacking component 13 to destroy the structure of the wheel 12 as designed, so that the wheel 12 can absorb and decompose the impact.

[0055] In some specific embodiments, the frame assembly 10 further includes a fixing bolt, and the connecting part 100 has a connecting hole, through which the fixing bolt passes and is fixedly connected to the frame 11. It is understood that, to improve the reliability of the hacking device assembly 13 during installation, a bolt connection can be provided to enhance the reliability of the hacking device assembly 13 on the frame 11. Thus, to make the connection between the frame assembly 10 and the frame 11 more reliable, a fixing bolt is used to connect the connecting part 100 and the frame 11, ensuring the reliable installation of the frame assembly 10 on the frame 11. This allows the frame assembly 10 to have high performance in the event of a collision, meeting usage requirements and ensuring the safety of the cab.

[0056] In some embodiments, it is suitable to use welding connections in addition to bolted connections for further fixation and restriction, so as to improve the reliability of the installation of the hacker assembly 13 on the frame 11, thereby enabling the hacker assembly 13 to more reliably hack the structure of the wheel 12 as designed, so as to make the frame assembly 10 more reliable in use.

[0057] It is understood that at least one of bolted and welded connections can be used according to the needs of different vehicle models, so that the arrangement of the hacker component 13 can meet the construction requirements of different vehicles, thereby improving the design applicability of this application.

[0058] Furthermore, in the actual use of this application, other fixed connection methods can be adopted, or the hacking component 13 can be integrated and installed on the A-pillar to further improve the reliability of the hacking component 13. This allows the hacking part 210 to contact the wheel and, upon collision, to hack the wheel structure after contact with the wheel. This allows the wheel structure to collapse after being hacked, thus absorbing the impact force generated during the collision and reducing the impact force on the passenger compartment, thereby improving the safety of the user in the passenger compartment.

[0059] In some embodiments, the hacking component 13 is a one-piece cast metal part. It is understood that by making the hacking component 13 a one-piece structural part, production steps are reduced, the production process is simplified, the connection strength between the hacking part 210 and the connecting part 100 is improved, and the structural strength of the hacking component 13 is increased. Of course, this application is not limited to this. Using a casting process simplifies the construction process, improves production efficiency, and provides high performance to meet the usage requirements of the hacking component 13. That is, the hacking component 13 has high structural strength so that it can, as designed, contact the wheel upon impact and break the wheel 12 structure as required, allowing the wheel 12 structure to collapse and absorb the impact after damage, thereby improving safety. Using a metal part increases structural strength, allowing the hacking component 13 to destroy the wheel 12 structure as designed, thereby collapsing and absorbing energy, and improving safety.

[0060] Specifically, high-strength steel, such as 610L, can be used to make the hacking component 13, resulting in higher structural performance. Using a casting process further enhances the structural strength of the hacking component 13 after production. Furthermore, other high-strength materials can be used to construct the hacking component 13, ensuring it can destroy the tires and rims as designed. This allows the hacking components made of other materials to function as designed, improving vehicle safety while reducing costs.

[0061] The vehicle 20 according to an embodiment of the present invention includes: a frame assembly 10 as described above. The frame assembly is provided with a breakdown component as shown above. Since the breakdown portion of the breakdown component is disposed opposite to the wheel, in the event of a minor impact or other small impact, the breakdown component can damage the wheel structure, allowing the wheel structure to further collapse and absorb energy after damage, thereby reducing the impact force acting on the frame and the cab, and improving the safety of the user while driving in the cab.

[0062] It should be noted that during the operation of vehicle 20, when a frontal impact occurs, the impact force is designed to act on the front of vehicle 20 to drive the front structure to deform. During deformation, the impact force is absorbed to reduce the impact on the cab. However, in actual impacts, due to the high rigidity of the wheel hubs of wheel 12, the impact is more likely to be transmitted than absorbed, resulting in a greater impact on the cab. Furthermore, after the wheel collapses and absorbs energy, the impact force is further transmitted to the frame, driving the frame 11 to deform. During deformation, energy is further absorbed to reduce the magnitude of the impact force on the cab, making the cab space safer and more reliable, thereby improving the safety of the user driving vehicle 20.

[0063] Understandably, the frame assembly 10 shown above is suitable for installation on the lower section of the A-pillar of the frame 11. Since the hacking unit 210 has a sharp transverse blade 211 facing the wheel 12, in the event of a collision, the transverse blade 211 is suitable for contacting the tire of the wheel 12. Because the transverse blade 211 is sharp, it can damage the tire. Then, the transverse blade 211 contacts the tire 15 and the rim 16, allowing it to break the rigid structure of the rim, thus enabling further rim collapse to absorb the impact and prevent the impact from being transmitted to the cab and affecting its safety. Of course, it should be understood that the position of the hacking component 13 can be adjusted according to requirements.

[0064] It should also be noted that the frame assembly 10 and the frame 11 can be fixed together by welding or bolting, depending on the requirements. Furthermore, because the frame assembly 10, as shown above, is located on the frame 11, it protects the cab, allowing for material savings and reduced production costs during the cab's design process. Additionally, by using the impact absorber component 13 to absorb the impact force on the cab, the structural material of the cab can be reduced, ensuring high structural strength and safety while also lowering production costs.

[0065] Furthermore, the chassis assembly 10 is equipped with the aforementioned hacking component 13, which allows it to bypass the wheel 12 structure. This allows the wheel 12 to collapse and absorb energy, protecting the cab structure and improving driving safety for the user inside the cab. Therefore, the sill beam reinforcement beam or cab filling beam can be reduced or eliminated as needed, reducing chassis weight and lowering costs.

[0066] Thus, it is suitable to provide a frame assembly 10 as shown above in the vehicle 20. By providing a hacking component 13 on one side of the wheel 12, it is suitable to drive the wheel 12 to contact the hacking component 13 in the event of an impact, so that the hacking component 13 can destroy the rigid structure of the wheel 12. The destroyed wheel 12 can absorb the impact, thereby improving the safety of the cab and thus improving the safety of the vehicle 20.

[0067] Other configurations and operations of the vehicle 20 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
