Description

Technical Field

[0001] This application relates to the field of electric vehicle technology, and more specifically to a front crossbeam assembly for a vehicle and the vehicle itself. Background Technology

[0002] An electric vehicle is a vehicle that uses electricity as its power source and is driven by an electric motor. Compared to traditional gasoline-powered vehicles, electric vehicles eliminate the engine in the front engine compartment and add a front trunk to increase the overall storage space of the vehicle.

[0003] As consumers' demands for personalization and entertainment increase, the need for front trunk space is also growing. However, the front engine compartment is one of the critical areas in a vehicle collision. Among numerous collision accidents, small overlap collisions (where the vehicle and an obstacle overlap by only 25%) have become one of the main scenarios threatening occupant safety due to their small contact area, concentrated energy, and susceptibility to localized crumpling of the vehicle's structure. Therefore, the front trunk needs to meet increasingly stringent safety requirements while still providing ample space.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] To address or improve to some extent the poor safety of vehicles with front trunks in existing technologies, this utility model provides a front crossbeam assembly for a vehicle. The vehicle includes a front trunk, a first front longitudinal beam and a second front longitudinal beam disposed opposite to each other and extending along the X direction of the vehicle; and the front crossbeam assembly includes a front crossbeam extending along the Y direction of the vehicle, with both ends of the front crossbeam configured to be respectively fixed to the first and second front longitudinal beams, wherein the front crossbeam is adapted to be positioned to extend through the front trunk in a vertical projection along the Z direction of the vehicle.

[0006] Those skilled in the art will understand that the front crossbeam assembly of this utility model for a vehicle includes a front crossbeam extending along the Y direction (i.e., left-right direction) of the vehicle. The two ends of the front crossbeam are respectively fixed to the first and second front longitudinal beams of the vehicle. In the assembled state, the front crossbeam is positioned with a vertical projection extending through the front trunk along the Z direction (i.e., up-down direction) of the vehicle. Thus, the front crossbeam assembly of this utility model can significantly improve the structural strength of the front trunk area, thereby improving the overall vehicle safety. Furthermore, the front crossbeam, the first front longitudinal beam, and the second front longitudinal beam together form a roughly "H"-shaped support structure, increasing the vehicle's Y-direction support and energy absorption capacity during obstacle avoidance contact in small offset conditions. The front crossbeam promptly disperses and transfers the impact force to the first and second front longitudinal beams, deflecting the obstacle and thus reducing the force on the vehicle during a collision, further improving overall vehicle safety.

[0007] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, a buffer cavity extending along the Y direction is formed within the front crossbeam. The buffer cavity enhances the structural strength and bending resistance of the front crossbeam, further improving the overall vehicle safety.

[0008] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, the front crossbeam includes: an upper bracket having a U-shaped upper body extending along the Y direction and opening downwards; and a lower bracket having a U-shaped lower body extending along the Y direction and opening upwards, wherein the U-shaped upper body is fastened to the U-shaped lower body to form the buffer cavity. By having the mutually fastened U-shaped upper and lower bodies together form the buffer cavity, the structure of the front crossbeam can be simplified, facilitating manufacturing.

[0009] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, the upper bracket further includes a first upper flange and a second upper flange extending in opposite directions from both ends of the U-shaped upper body along the X direction; the lower bracket further includes a first lower flange and a second lower flange extending in opposite directions from both ends of the U-shaped lower body along the X direction, wherein the first upper flange abuts against and is fixed to the first lower flange, and the second upper flange abuts against and is fixed to the second lower flange. By providing the first upper flange and the second upper flange at both ends of the U-shaped upper body, the entire upper bracket can have a roughly "U"-shaped longitudinal cross section, thereby improving structural stability. Correspondingly, by providing the first lower flange and the second lower flange at both ends of the U-shaped lower body, the entire lower bracket can also have a roughly "U"-shaped longitudinal cross section, thereby improving structural stability.

[0010] In the preferred embodiment of the front crossbeam assembly for a vehicle described above, the first upper flange and the first lower flange, as well as the second upper flange and the second lower flange, are fixedly connected by sealant and / or welding. This arrangement ensures a stable and secure connection between the upper and lower supports.

[0011] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, upper and lower reinforcing ribs extending along the Y direction are respectively provided on the U-shaped upper body and the U-shaped lower body; and / or the upper and lower supports are both made of hot-formed high-strength steel; and / or the upper and lower supports are both manufactured using a stamping process. The upper and lower reinforcing ribs increase the rigidity and structural strength of the U-shaped upper and lower bodies. The use of hot-formed high-strength steel ensures the structural strength of the upper and lower supports. The use of a stamping process ensures efficient processing.

[0012] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, the front crossbeam assembly further includes a left connecting bracket and a right connecting bracket respectively arranged at the left and right ends of the front crossbeam. The left connecting bracket is adapted to fix the front crossbeam to the first front longitudinal beam via a first mounting member, and the right connecting bracket is adapted to fix the front crossbeam to the second front longitudinal beam via a second mounting member. The arrangement of the left and right connecting brackets enhances the connection strength between the front crossbeam and the first and second longitudinal beams, improving the reliability of force transmission from the front crossbeam to the first and second front longitudinal beams. Furthermore, the first and second mounting members facilitate and securely fix the front crossbeam to the first and second longitudinal beams.

[0013] In the preferred embodiment of the front crossbeam assembly for a vehicle described above, each of the left connecting bracket and the right connecting bracket includes an upper fixing part and a lower fixing part opposite to each other, and a connecting part located between the upper fixing part and the lower fixing part, wherein the upper fixing part is located on the upper side of the front crossbeam, and the lower fixing part is located on the lower side of the front crossbeam. This arrangement gives the left and right connecting brackets a generally "U"-shaped structure, which is simple, stable, and easy to manufacture.

[0014] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, the front crossbeam assembly further includes a support sleeve, which is located within the buffer cavity and extends along the Z-direction, with both ends of the support sleeve abutting against the front crossbeam. The support sleeve supports the front crossbeam in the Z-direction within the buffer cavity, enhancing the support capacity within the buffer cavity of the front crossbeam, thereby improving the front crossbeam's resistance to deformation and impact in the Z-direction.

[0015] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, a through hole extending along the Z-direction is formed within the support sleeve to allow the corresponding first mounting member or second mounting member to pass through it. Providing a through hole extending along the Z-direction within the support sleeve not only reduces the weight of the support sleeve, achieving a lighter front crossbeam assembly, but also facilitates the positioning and installation of the first and second mounting members. Furthermore, since both the first and second mounting members are arranged along the Z-direction, the connection strength and rigidity between the front crossbeam and the first and second front longitudinal beams in the horizontal plane can be improved, thereby enhancing the shear resistance of the front crossbeam assembly.

[0016] In the preferred embodiment of the front crossbeam assembly for a vehicle described above, the first mounting component and the second mounting component are bolts. The bolts provide a simple structure and facilitate assembly and disassembly.

[0017] In the preferred embodiment of the aforementioned front crossbeam assembly for a vehicle, each of the left connecting bracket and the right connecting bracket is provided with a locating pin hole, and each locating pin hole allows the locating pins on the corresponding first front longitudinal beam and second front longitudinal beam to pass through it. The provision of locating pin holes not only improves the installation accuracy and efficiency of the left and right connecting brackets, but also enhances the shear resistance of the front crossbeam assembly.

[0042] To address or improve to some extent the poor safety of vehicles with front trunks in the prior art, this utility model provides a front crossbeam assembly 200 for a vehicle 100 and a vehicle 100. The vehicle 100 includes a front trunk 110, a first front longitudinal beam 120a and a second front longitudinal beam 120b disposed opposite to each other and extending along the X direction of the vehicle 100; and the front crossbeam assembly 200 includes a front crossbeam 210 extending along the Y direction of the vehicle 100, and the two ends of the front crossbeam 210 are configured to be fixed to the first front longitudinal beam 120a and the second front longitudinal beam 120b respectively, wherein the front crossbeam 210 is adapted to be positioned to extend through the front trunk 110 in a vertical projection along the Z direction of the vehicle 100.

[0043] Figure 1 This is a partial structural schematic diagram of an embodiment of the vehicle of this utility model. (As shown...) Figure 1 As shown, in one or more embodiments, the vehicle 100 of this utility model includes a front trunk 110, a first front longitudinal beam 120a, a second front longitudinal beam 120b, and a front crossbeam assembly 200. The first front longitudinal beam 120a and the second front longitudinal beam 120b are arranged opposite to each other and extend along the X direction (i.e., the longitudinal direction) of the vehicle 100. Based on Figure 1As shown, the first front longitudinal beam 120a is located on the left side of the vehicle 100, while the second front longitudinal beam 120b is located on the right side of the vehicle 100. Alternatively, the positions of the first front longitudinal beam 120a and the second front longitudinal beam 120b can be interchanged. The first front longitudinal beam 120a and the second front longitudinal beam 120b can be made of suitable metal materials to give them good mechanical strength. The front trunk 110 is located in the front engine compartment area of ​​the vehicle 100. The material, shape, and size of the front trunk 110 can be adjusted according to actual needs. The front crossbeam assembly 200 includes a front crossbeam 210 extending along the Y direction (i.e., the left-right direction) of the vehicle 100. The left and right ends of the front crossbeam 210 are respectively fixed to the first front longitudinal beam 120a and the second front longitudinal beam 120b. In the assembled state, the front crossbeam 210 is positioned to extend through the front trunk 110 in a vertical projection along the Z direction (i.e., the up-down direction) of the vehicle 100. Therefore, by installing a front crossbeam assembly 200 at the lower part of the front trunk 110, the structural strength of the front trunk 110 area of ​​the vehicle 100 of this utility model can be significantly improved, thereby enhancing the safety of the entire vehicle. Furthermore, the front crossbeam 210, the first front longitudinal beam 120a, and the second front longitudinal beam 120b together form a roughly "H"-shaped support structure, increasing the Y-direction support and energy absorption capacity of the vehicle 100 in obstacle avoidance contact under small offset conditions. The front crossbeam 210 promptly disperses and transmits the impact force to the first front longitudinal beam 120a and the second front longitudinal beam 120b, deflecting the obstacle and thus reducing the force on the entire vehicle during a collision, further improving the safety of the entire vehicle.

[0044] It should be noted that the vehicle 100 of this utility model also includes, but is not limited to, components such as electric motors, wheels, gearboxes, and transmission structures, which will not be described in detail here. Furthermore, the vehicle 100 can be an electric vehicle, a hybrid vehicle, or other suitable types of vehicles.

[0046] Figure 2 This is a structural schematic diagram of an embodiment of the present invention used in a vehicle's front crossbeam assembly; Figure 3 This is an exploded schematic diagram of the front crossbeam in the front crossbeam assembly of a vehicle, which is an application of this utility model. Figure 4 It is along Figure 2 A partially enlarged view of the cross-sectional schematic diagram obtained by the AA section line shown. (See attached image.) Figures 2-4As shown, in one or more embodiments, the front crossbeam assembly 200 of this utility model includes a front crossbeam 210 extending along the Y direction (i.e., the left-right direction) of the vehicle 100. In one or more embodiments, a buffer cavity 213 extending along the Y direction of the vehicle 100 is formed within the front crossbeam 210. The provision of the buffer cavity 213 can improve the structural strength and bending resistance of the front crossbeam 210, further enhancing the safety of the entire vehicle.

[0047] like Figure 3 As shown, in one or more embodiments, the front crossbeam 210 includes an upper support 211 and a lower support 212 opposite to each other. The upper support 211 has a U-shaped upper body 2111 extending in the Y direction and opening downwards. The lower support 212 has a U-shaped lower body 2121 extending in the Y direction and opening upwards. In the assembled state, the U-shaped upper body 2111 is fastened to the U-shaped lower body 2121 to form a buffer cavity 213. By having the mutually fastened U-shaped upper body 2111 and U-shaped lower body 2121 together form the buffer cavity 213, the structure of the front crossbeam 210 can be simplified, facilitating processing.

[0048] See also Figure 3 In one or more embodiments, the upper support 211 further includes a first upper flange 2112 and a second upper flange 2113. The first upper flange 2112 and the second upper flange 2113 extend from both ends of the U-shaped upper body 2111 in opposite directions along the X direction. Based on Figure 3 As shown, the first upper flange 2112 is located on the front side of the U-shaped upper body 2111, while the second upper flange 2113 is located on the rear side of the U-shaped upper body 2111. By providing the first upper flange 2112 and the second upper flange 2113 at both ends of the U-shaped upper body 2111, the entire upper support 211 can have a roughly "U"-shaped longitudinal cross-section, thereby improving the stability of the structure. In one or more embodiments, the lower support 212 includes a first lower flange 2122 and a second lower flange 2123. The first lower flange 2122 and the second lower flange 2123 extend from both ends of the U-shaped lower body 2121 in opposite directions along the X direction. Based on Figure 3As shown, the first lower flange 2122 is located on the front side of the U-shaped lower body 2121, while the second lower flange 2123 is located on the rear side of the U-shaped lower body 2121. Correspondingly, by providing the first lower flange 2122 and the second lower flange 2123 at both ends of the U-shaped lower body 2121, the entire lower support 212 can have a roughly "U"-shaped longitudinal cross-section, thereby improving structural stability. In the assembled state, the first upper flange 2112 abuts against and is fixed to the first lower flange 2122, and the second upper flange 2113 abuts against and is fixed to the second lower flange 2123. The first upper flange 2112 and the first lower flange 2122, the second upper flange 2113 and the second lower flange 2123 are configured to form a fixed connection through sealant and / or welding, thereby creating a stable and secure connection between the upper support 211 and the lower support 212. The fixed connection between the first upper flange 2112 and the first lower flange 2122, the second upper flange 2113 and the second lower flange 2123 can also be riveting or other connection methods suitable for actual installation.

[0049] See also Figure 3 In one or more embodiments, upper reinforcing ribs 21111 and lower reinforcing ribs 21211 extending along the Y direction are respectively provided on the U-shaped upper body 2111 and U-shaped lower body 2121. The provision of upper reinforcing ribs 21111 and lower reinforcing ribs 21211 increases the rigidity and structural strength of the U-shaped upper body 2111 and U-shaped lower body 2121. It should be noted that the number, length, and arrangement of upper reinforcing ribs 21111 and lower reinforcing ribs 21211 can be adjusted according to actual needs. In one or more embodiments, the material of both the upper support 211 and the lower support 212 is hot-formed high-strength steel. For example, the upper support 211 is hot-formed high-strength steel with a strength of 1.5 GPa, while the lower support 212 is hot-formed high-strength steel with a strength of 2.0 GPa. The provision of hot-formed high-strength steel ensures the structural strength of the upper support 211 and lower support 212. In one or more embodiments, both the upper bracket 211 and the lower bracket 212 are manufactured by stamping, which enables the upper bracket 211 and the lower bracket 212 to be integrally formed, ensuring processing efficiency.

[0050] See also Figure 3 In one or more embodiments, the front crossbeam assembly 200 further includes a left connecting bracket 214a and a right connecting bracket 214b. The left connecting bracket 214a and the right connecting bracket 214b are respectively arranged at the left and right ends of the front crossbeam 210. The left connecting bracket 214a fixes the front crossbeam 210 to the first front longitudinal beam 120a through a first mounting member 215a, and the right connecting bracket 214b fixes the front crossbeam 210 to the second front longitudinal beam 120b through a second mounting member 215b.

[0051] See also Figure 3 In one or more embodiments, each of the left connecting bracket 214a and the right connecting bracket 214b includes an upper fixing part 2141 and a lower fixing part 2142 opposite to each other, and a connecting part 2143 located between the upper fixing part 2141 and the lower fixing part 2142. Through the above arrangement, the left connecting bracket 214a and the right connecting bracket 214b have a generally "U"-shaped structure, which is simple, stable, and easy to manufacture. In the assembled state, the upper fixing part 2141 is located on the upper side of the front crossbeam 210, and the lower fixing part 2142 is located on the lower side of the front crossbeam 210. Both ends of the front crossbeam 210 are provided with openings communicating with the buffer cavity 213, and the connecting part 2143 covers the left and right openings of the front crossbeam 210 respectively, thereby improving the structural strength of the entire front crossbeam assembly 200. In addition, the U-shaped left connecting bracket 214a and right connecting bracket 214b can stably and firmly clamp and fix the upper bracket 211 and the lower bracket 212 together to enhance the sealing of the buffer cavity inside the front crossbeam and further enhance the structural strength of the front crossbeam 210.

[0052] See also Figure 3 In one or more embodiments, each of the left connecting bracket 214a and the right connecting bracket 214b has two mounting holes 2144 spaced apart from each other. The two mounting holes 2144 on the left connecting bracket 214a mate with the first mounting member 215a to fix the front crossbeam 210 to the first front longitudinal beam 120a. Correspondingly, the two mounting holes 2144 on the right connecting bracket 214b mate with the second mounting member 215b to fix the front crossbeam 210 to the second front longitudinal beam 120b. In one or more embodiments, the first mounting member 215a and the second mounting member 215b are bolts, which provides a simple structure and facilitates assembly and disassembly. Alternatively, each of the left connecting bracket 214a and the right connecting bracket 214b may also have a suitable number of mounting holes 2144, such as one, three, etc.

[0053] like Figure 4 As shown, in one or more embodiments, the front crossbeam assembly 200 of this utility model further includes a support sleeve 216. The support sleeve 216 is located within the buffer cavity 213 and extends along the Z direction. Both ends of the support sleeve 216 abut against the front crossbeam 210. Based on Figure 4As shown, the upper end of the support sleeve 216 abuts against the lower surface of the upper bracket 211, and the lower end of the support sleeve 216 abuts against the upper surface of the lower bracket 212. The support sleeve 216 forms a fixed connection with the upper bracket 211 and / or the lower bracket 212. The connection method can be, but is not limited to, welding. The provision of the support sleeve 216 can enhance the deformation resistance and impact resistance of the front crossbeam 210. In one or more embodiments, a through hole 2161 extending along the Z direction is formed in the support sleeve 216, and in the assembled state, a first mounting member 215a or a second mounting member 215b extends through the through hole 2161 in the support sleeve 216. Therefore, during installation, the first mounting member 215a (or the second mounting member 215b) will sequentially pass through the mounting hole 2144 on the left connecting bracket 214a (or the right connecting bracket 214b) and the through hole 2161 on the support sleeve 216, forming a threaded connection with the screw hole on the first front longitudinal beam 120a (or the second front longitudinal beam 120b). Alternatively, the first mounting member 215a and the second mounting member 215b can also directly pass through the mounting hole 2144 and form a threaded connection with the first front longitudinal beam 120a and the second front longitudinal beam 120b. The number of support sleeves 216 can be four. The number of support sleeves 216 can also be set according to the actual number of the first mounting member 215a and the second mounting member 215b. Alternatively, multiple independent support sleeves 216 can also be provided in the buffer cavity 213, without matching the first mounting member 215a and the second mounting member 215b.
