In addition, the upper crossbeam of the front fascia occupies a large amount of vehicle space, resulting in poor space utilization. Utility Model Content

[0006] The front upper crossbeam assembly according to an embodiment of the present invention includes: an upper crossbeam having a left beam connecting end and a right beam connecting end in the width direction of the vehicle, the left beam connecting end being adapted to connect with the left longitudinal beam of the vehicle, and the right beam connecting end being adapted to connect with the right longitudinal beam of the vehicle; a left wiper mounting plate connected to the upper crossbeam, the left wiper mounting plate having a left plate connecting end adapted to connect with the left longitudinal beam; and a right wiper mounting plate connected to the upper crossbeam, the right wiper mounting plate having a right plate connecting end adapted to connect with the right longitudinal beam; wherein, the distance between the left beam connecting end and the left plate connecting end gradually increases in the direction from the right beam connecting end to the left beam connecting end; and the distance between the right beam connecting end and the right plate connecting end gradually increases in the direction from the left beam connecting end to the right beam connecting end.
[0007] According to the embodiment of this utility model, the front upper crossbeam assembly forms a figure-eight joint structure at the connection points between the front upper crossbeam assembly and the left and right longitudinal beams, thereby increasing the area of the overlapping joints between the front upper crossbeam assembly and the left and right longitudinal beams. This achieves the effect of enhancing the connection strength between the upper crossbeam and the left and right longitudinal beams without increasing the cross-sectional dimensions of the front upper crossbeam assembly, thus reducing the weight and cost of the front upper crossbeam assembly. Furthermore, since the middle dimension of the front upper crossbeam assembly is smaller than the dimension of the overlapping joints at both ends of the front upper crossbeam assembly, the space occupied by the front upper crossbeam assembly in the vehicle can be reduced, thereby improving space utilization.

[0013] According to the embodiment of the present invention, the front engine compartment assembly forms a figure-eight joint structure at the connection points between the upper crossbeam assembly and the left and right longitudinal beams, thereby increasing the area of the overlapping joints between the upper crossbeam assembly and the left and right longitudinal beams. This achieves the effect of enhancing the connection strength between the upper crossbeam and the left and right longitudinal beams without increasing the cross-sectional dimensions of the upper crossbeam assembly, thus reducing the weight and cost of the upper crossbeam assembly. Furthermore, since the middle dimension of the upper crossbeam assembly is smaller than the dimension of the overlapping joints at both ends of the upper crossbeam assembly, the space occupied by the upper crossbeam assembly in the vehicle can be reduced, thereby improving space utilization.

Without increasing the cross-sectional dimensions of the upper crossbeam assembly of the front bulkhead, the connection strength between the upper crossbeam and the left and right longitudinal beams can be enhanced, thereby reducing the weight and cost of the upper crossbeam assembly of the front bulkhead. Furthermore, the middle dimension of the upper crossbeam assembly of the front bulkhead is smaller than the dimension of the overlapping joints at both ends of the upper crossbeam assembly of the front bulkhead, which can reduce the space occupied by the upper crossbeam assembly of the front bulkhead in the vehicle and improve the space utilization rate.

[0039] The following is combined Figures 1-5 This invention provides a detailed description of the front upper crossbeam assembly 10, the front engine compartment assembly 100, and the vehicle according to embodiments of the present invention.
[0040] Reference Figure 1 and Figure 2 As shown, the front upper crossbeam assembly 10 according to an embodiment of the present utility model includes: an upper crossbeam 1, a left wiper mounting plate 2, and a right wiper mounting plate 3, which are positioned in the width direction of the vehicle (e.g., ...). Figure 1 and Figure 2 (As shown in the left-right direction), the upper crossbeam 1 has a left beam connecting end 11 and a right beam connecting end, the left beam connecting end 11 is adapted to be connected to the left longitudinal beam 20 of the vehicle, and the right beam connecting end is adapted to be connected to the right longitudinal beam 30 of the vehicle. The left wiper mounting plate 2 is connected to the upper crossbeam 1 and has a left plate connecting end 21, which is adapted to be connected to the left longitudinal beam 20. The right wiper mounting plate 3 is connected to the upper crossbeam 1 and has a right plate connecting end, which is adapted to be connected to the right longitudinal beam 30. In the direction from the right beam connecting end to the left beam connecting end 11, the distance between the left beam connecting end 11 and the left plate connecting end 21 gradually increases, and in the direction from the left beam connecting end 11 to the right beam connecting end, the distance between the right beam connecting end and the right plate connecting end gradually increases.
[0041] Specifically, the upper front crossbeam assembly 10 can be used in vehicles such as long-nose trucks. The upper front crossbeam assembly 10 can be installed in the front engine compartment of the vehicle and can be used to strengthen the structural strength of the vehicle's front bulkhead. The upper crossbeam 1 can be constructed as a plate structure. The left beam connecting end 11 of the upper crossbeam 1 extends rearward and can be welded to the inner plate of the left longitudinal beam 20 (shotgun on the left side of the vehicle). The right beam connecting end of the upper crossbeam 1 extends rearward and can be welded to the inner plate of the right longitudinal beam 30 (shotgun on the right side of the vehicle).
[0042] The left wiper mounting plate 2 can be used to install the vehicle's wiper. The left wiper mounting plate 2 can be constructed as a plate structure. The upper, right, and lower ends of the left wiper mounting plate 2 can have first flanges 22. The left wiper mounting plate 2 is welded to the side of the upper crossbeam 1 facing outwards via the first flanges 22. The left plate connecting end 21 of the left wiper mounting plate 2 extends forward and can be welded to the inner plate of the left longitudinal beam 20. From the right beam connecting end 11 to the left beam connecting end 11 (i.e., from right to left), the distance between the left beam connecting end 11 and the left plate connecting end 21 gradually increases, forming a "trumpet" structure. Figure 2 The structure forms an "eight" shaped joint structure. The "eight" shaped joint structure can increase the connection area between the left beam connection end 11 and the left plate connection end 21 and the left longitudinal beam 20. The "eight" shaped joint structure can enhance the connection strength between the front upper crossbeam assembly 10 and the left longitudinal beam 20, so as to reduce the risk of the front upper crossbeam assembly 10 separating from the left longitudinal beam 20 under the action of external force (for example, the upper crossbeam 1 is impacted by an external force).
[0043] Similarly, the right wiper mounting plate 3 can be used to install the vehicle's wiper. The right wiper mounting plate 3 can be constructed as a plate structure. The upper, left and lower ends of the right wiper mounting plate 3 can have second flanges. The right wiper mounting plate 3 is welded to the side of the upper crossbeam 1 facing outward through the second flanges. The right plate connecting end of the right wiper mounting plate 3 extends forward and is welded to the inner plate of the right longitudinal beam 30. In the direction from the left beam connection end 11 to the right beam connection end, that is, from left to right, the distance between the right beam connection end and the right plate connection end gradually increases, forming a "trumpet mouth" structure. The right beam connection end and the right plate connection end form an "eight" shaped joint structure. The "eight" shaped joint structure can increase the connection area between the right beam connection end and the right plate connection end and the right longitudinal beam 20. The "eight" shaped joint structure can enhance the connection strength between the front upper crossbeam assembly 10 and the right longitudinal beam 30, so as to reduce the risk of the front upper crossbeam assembly 10 separating from the right longitudinal beam 30 under the action of external force (for example, the upper crossbeam 1 being impacted by an external force).
[0044] Compared to related technologies that set the middle section of the upper front beam, the overlap joint between the upper front beam and the left longitudinal beam, and the overlap joint between the upper front beam and the right longitudinal beam to be of equal size, and enhance the overall rigidity of the upper front beam by increasing the cross-sectional size of the upper front beam, the upper front beam assembly 10 of this utility model is designed with an "eight"-shaped joint structure. This ensures that the connection strength between the upper front beam assembly 10 and the left longitudinal beam 20 and the right longitudinal beam 30 meets the requirements. Furthermore, the middle dimension of the upper front beam assembly 10 is smaller than the dimensions of the overlap joints at both ends of the upper front beam assembly 10, which reduces the space occupied by the upper front beam assembly 10 in the vehicle and improves space utilization. In addition, the cross-sectional dimensions of the front upper crossbeam assembly 10 are smaller than those of related technologies, which can avoid problems such as increased weight, increased cost, and poor lightweighting caused by increasing the cross-sectional dimensions of the front upper crossbeam as in related technologies. This is conducive to achieving a lightweight design of the front upper crossbeam assembly 10 and can save costs.
[0045] In the above embodiment, by forming a figure-eight joint structure at the connection points of the upper front crossbeam assembly 10 with the left longitudinal beam 20 and the right longitudinal beam 30, the area of the overlapping joints of the upper front crossbeam assembly 10 with the left longitudinal beam 20 and the right longitudinal beam 30 is increased. Without increasing the cross-sectional dimensions of the upper front crossbeam assembly 10, the connection strength between the upper crossbeam 10 and the left longitudinal beam 20 and the right longitudinal beam 30 can be enhanced, thereby reducing the weight and cost of the upper front crossbeam assembly 10. Furthermore, since the middle dimension of the upper front crossbeam assembly 10 is smaller than the dimension of the overlapping joints at both ends of the upper front crossbeam assembly 10, the space occupied by the upper front crossbeam assembly 10 in the vehicle can be reduced, thereby improving space utilization.
[0046] In some embodiments of this utility model, such as Figure 3 As shown, the upper crossbeam 1 has a crossbeam groove 12 extending along the width direction of the vehicle. The front upper crossbeam assembly 10 also includes a windshield crossbeam lower plate 4, which is connected to the upper crossbeam 1 and closes the groove of the crossbeam groove 12.
[0047] The upper crossbeam 1 can be constructed as a plate structure with a "C" shaped cross section. The upper crossbeam 1 can have a crossbeam groove 12 extending along the width direction of the vehicle. The groove opening of the crossbeam groove 12 faces the driver's cabin of the vehicle. The lower plate 4 of the windshield crossbeam can be constructed as a plate structure. The lower plate 4 of the windshield crossbeam can extend in the left and right direction. The two ends of the lower plate 4 of the windshield crossbeam can have a third flange 41 in the up and down direction. The lower plate 4 of the windshield crossbeam can be welded to the two ends of the upper crossbeam 1 in the up and down direction through the third flange 41 to close the groove opening of the crossbeam groove 12, so that the cross sections of the upper crossbeam 1 and the lower plate 4 of the windshield crossbeam are closed sections. When the frontal upper beam assembly 10 is involved in a frontal collision, compared to the design of the front upper beam with an open cross section in related technologies, the closed cross section structure design of this utility model embodiment can increase the moment of inertia of the front upper beam assembly 10, thereby improving the bending and torsional stiffness of the front upper beam assembly 10. This allows the front upper beam assembly 10 to withstand greater impact forces, improves the bending and torsional stiffness of the vehicle's cab, making the cab less prone to bending, and enhances the NVH (noise, vibration, and harshness) performance of the cab, as well as the modal characteristics of the vehicle's windshield.
[0048] In some embodiments of this utility model, such as Figure 2 As shown, in the width direction of the vehicle, the lower plate 4 of the windshield beam has a left lower plate connecting end 42 and a right lower plate connecting end. The left lower plate connecting end 42 is adapted to be connected to the left longitudinal beam 20 through the left beam connecting end 11, and the right lower plate connecting end is adapted to be connected to the right longitudinal beam 30 through the right beam connecting end.
[0049] In this design, along the left-right direction, the lower plate 4 of the windshield crossbeam can have a corresponding lower left plate connecting end 42 and a lower right plate connecting end. The lower left plate connecting end 42 can be connected to the inner plate of the left longitudinal beam 20 through the left beam connecting end 11. The lower left plate connecting end 42, the left beam connecting end 11, and the left longitudinal beam 20 can be welded together. Similarly, the lower right plate connecting end can be connected to the inner plate of the right longitudinal beam 30 through the right beam connecting end. The lower right plate connecting end, the right beam connecting end, and the right longitudinal beam 30 can be welded together. This configuration can further enhance the connection strength between the upper crossbeam 1 and the left longitudinal beam 20 and the right longitudinal beam 30, thereby improving the connection stability between the front upper crossbeam assembly 10 and the left and right longitudinal beams 20 and 30, and thus improving the reliability of the front upper crossbeam assembly 10.
[0050] In some embodiments of this utility model, such as Figure 1 As shown, the front upper crossbeam assembly 10 also includes a wiper motor bracket 5, which is connected to the upper crossbeam 1 and is located between the left wiper mounting plate 2 and the right wiper mounting plate 3.
[0051] The wiper motor bracket 5 is used to mount the wiper motor. The wiper motor bracket 5 can be connected to the upper crossbeam 1 via welding, snap-fit connection, or bolt connection. The wiper motor bracket 5 can be located between the left wiper mounting plate 2 and the right wiper mounting plate 3, facilitating the arrangement of the transmission components between the motor and the wiper arm, so that the wiper motor can drive the wipers mounted on the left and right wiper mounting plates 2 and 3 to swing. Furthermore, the middle position of the upper crossbeam 1 (the middle position refers to any position between the left and right wiper mounting plates 2 and 3 on the upper crossbeam 1) provides a large mounting space, allowing the installation position of the wiper motor bracket 5 to be selected according to actual needs, reducing installation difficulty and providing a certain degree of flexibility.
[0052] As some embodiments of this utility model, such as Figure 1 As shown, a first wiper mounting plate 7 and a second wiper mounting plate 8 can be selectively installed on the upper crossbeam 1. Both the first wiper mounting plate 7 and the second wiper mounting plate 8 can be used to install wipers. The first wiper mounting plate 7 and the second wiper mounting plate 8 can be welded to the upper crossbeam 1. Along the left-right direction, the left wiper mounting plate 2, the first wiper mounting plate 7, the second wiper mounting plate 8 and the right wiper mounting plate 3 are arranged in sequence at intervals to integrate the left wiper mounting plate 2, the first wiper mounting plate 7, the second wiper mounting plate 8 and the right wiper mounting plate 3 into the upper crossbeam 1. For left-hand drive vehicles, the two wipers can be installed on the left wiper mounting plate 2 and the first wiper mounting plate 7 respectively. For right-hand drive vehicles, the two wipers can be installed on the right wiper mounting plate 3 and the second wiper mounting plate 8 respectively. For vehicles with two wipers, the two wipers can be installed on the left wiper mounting plate 2 and the right wiper mounting plate 3 respectively. By setting multiple wiper mounting plates, the front upper crossbeam assembly 10 can be used for left-hand drive vehicles, right-hand drive vehicles, and vehicles with two wipers, so as to achieve the effect of parts sharing, reduce the development cost of the cab, reduce the types of parts, reduce the difficulty of maintenance and management, and have greater flexibility.
[0053] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the upper crossbeam 1 is constructed as an arched beam protruding forward of the vehicle.
[0054] The upper crossbeam 1 can be constructed as an arched beam protruding forward of the vehicle; in other words, the upper crossbeam 1 can be constructed as a forward-convex bow-shaped structure. This arched beam structure improves the upper crossbeam 1's resistance to frontal impact loads. When a frontal collision occurs, compared to related technologies where the front upper crossbeam is set laterally (lateral is...),... Figure 1The straight design (in the left and right directions) allows the frontal impact force acting on the upper crossbeam 1 in this embodiment to be transmitted to the left and right ends of the upper crossbeam 1 through the arched beam structure, to the left longitudinal beam 20 and the right longitudinal beam 30, and then to other parts of the vehicle body. This disperses the impact energy received by the upper crossbeam 1 through the vehicle body, thereby reducing the degree of damage to the upper crossbeam 1 from the impact. Furthermore, by constructing the upper crossbeam 1 as an arched beam protruding forward of the vehicle, a larger crumple zone can be provided behind the upper crossbeam 1, thereby reducing the amount of intrusion of the front upper crossbeam assembly 10 into the passenger compartment when impacted. This reduces the risk of injury to passengers in the passenger compartment caused by the upper crossbeam 1, thereby improving the deformation resistance of the upper crossbeam 1 under frontal impact load, which is beneficial to improving the collision performance and safety performance of the upper crossbeam 1.
[0055] It should be noted that new energy heavy trucks are heavier than traditional fuel heavy trucks, and the manufacturing cost of new energy heavy trucks is higher. New energy heavy trucks also have higher requirements for the structural strength performance, lightweighting degree, and manufacturing cost of the front upper crossbeam assembly 10. Therefore, the front upper crossbeam assembly 10 proposed in this utility model has advantages, is more adaptable to market development trends, and has good usage effects and market prospects.
[0056] Reference Figures 1-4 As shown, the front engine compartment assembly 100 according to an embodiment of the present utility model includes: a left longitudinal beam 20, a right longitudinal beam 30, and a front upper crossbeam assembly 10. In the width direction of the vehicle, the left longitudinal beam 20 and the right longitudinal beam 30 are arranged at intervals relative to each other, and the front upper crossbeam assembly 10 is the aforementioned front upper crossbeam assembly 10.
[0057] In this design, the left longitudinal beam 20 and the right longitudinal beam 30 are spaced apart in the left-right direction. The upper crossbeam assembly 10 of the front bulkhead is connected between the left longitudinal beam 20 and the right longitudinal beam 30. The connection between the upper crossbeam assembly 10 of the front bulkhead and the left longitudinal beam 20 and the right longitudinal beam 30 forms an "eight"-shaped joint structure to increase the area of the overlapping joint between the upper crossbeam assembly 10 of the front bulkhead and the left longitudinal beam 20 and the right longitudinal beam 30. This enhances the connection strength between the upper crossbeam 10 and the left longitudinal beam 20 and the right longitudinal beam 30 without increasing the cross-sectional dimensions of the upper crossbeam assembly 10, thereby reducing the weight and cost of the upper crossbeam assembly 10. Furthermore, the middle dimension of the upper crossbeam assembly 10 is smaller than the dimension of the overlapping joint at both ends of the upper crossbeam assembly 10, which reduces the space occupied by the upper crossbeam assembly 10 in the vehicle and improves space utilization.
[0058] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the front engine compartment assembly 100 also includes a front engine compartment support beam 6, one end of which is detachably connected to the left longitudinal beam 20 in the width direction of the vehicle, and the other end of which is detachably connected to the right longitudinal beam 30.
[0059] The front cabin support beam 6 can be connected between the left longitudinal beam 20 and the right longitudinal beam 30. The front cabin support beam 6 can be used to support the engine compartment. In the left-right direction, one end of the front cabin support beam 6 is detachably connected to the left longitudinal beam 20, and the other end of the front cabin support beam 6 is detachably connected to the right longitudinal beam 30. Both ends of the front cabin support beam 6 can be detachably connected to the left longitudinal beam 20 and the right longitudinal beam 30 by fasteners, such as bolts or locking pins. This arrangement facilitates the disassembly of the front cabin support beam 6. Compared with the design of welding the front cabin support beam to the left and right longitudinal beams in related technologies, the front engine compartment assembly 100 of this utility model embodiment can disassemble the front cabin support beam 6 to facilitate the maintenance of the cockpit, thereby reducing the difficulty of maintenance and the workload of maintenance personnel.
[0060] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the front compartment support beam 6 is symmetrical about the width of the vehicle.
[0061] The front compartment support beam 6 can be fixed with multiple accessories 40, which can be used to install other vehicle parts. In related technologies, after the parts are installed on the front compartment support beam, the front compartment support beam can only be used for left-hand drive or right-hand drive vehicles. In this embodiment of the utility model, the front compartment support beam 6 is symmetrical in the width direction of the vehicle. Depending on the vehicle model, one end of the front compartment support beam 6 can be connected to one of the left longitudinal beam 20 and the right longitudinal beam 30, and the other end of the front compartment support beam 6 can be connected to the other of the left longitudinal beam 20 and the right longitudinal beam 30. That is, the front compartment support beam 6 can be rotated 180° for use, and the positions of the two ends of the front compartment support beam 6 can be interchanged. Depending on the vehicle model, the corresponding connection relationship between the two ends of the front compartment support beam 6 and the left longitudinal beam 20 and the right longitudinal beam 30 can be changed so that the front compartment support beam 6 can be used for both left-hand drive and right-hand drive vehicles. This eliminates the need to design two different front compartment support beams for left-hand drive and right-hand drive vehicles as in related technologies. This reduces the difficulty of designing and manufacturing the front compartment support beam 6, lowers production costs, and enhances the applicability of the front compartment support beam 6.
[0062] In some embodiments of this utility model, such as Figure 5 As shown, the front compartment support beam 6 has a roll-formed reinforcing rib 61 that extends along the width direction of the vehicle.
[0063] The front compartment support beam 6 may have a roll-formed reinforcing rib 61. The reinforcing rib 61 protrudes towards the front of the vehicle and can extend in the left and right directions. The reinforcing rib 61 can disperse the stress on the front compartment support beam 6 and avoid stress concentration, thereby strengthening the structural strength of the front compartment support beam 6 and improving the reliability of the front compartment support beam 6.
[0064] In addition, the front cabin support beam 6 can be made of high-strength steel by roll forming. Compared with the design of manufacturing the front cabin support beam by traditional stamping technology in related technologies, the front cabin support beam 6 of this utility model embodiment has a relatively small cross-sectional size. In other words, the thickness of the front cabin support beam 6 is smaller, so as to achieve the purpose of lightweight design and save manufacturing material costs.
[0065] The vehicle according to this utility model embodiment includes the front engine compartment assembly 100 of the above embodiment. By forming a figure-eight joint structure at the connection points of the upper crossbeam assembly 10 with the left longitudinal beam 20 and the right longitudinal beam 30, the area of the overlapping joints of the upper crossbeam assembly 10 with the left longitudinal beam 20 and the right longitudinal beam 30 is increased. Without increasing the cross-sectional dimensions of the upper crossbeam assembly 10, the connection strength between the upper crossbeam 10 and the left longitudinal beam 20 and the right longitudinal beam 30 can be enhanced, thereby reducing the weight and cost of the upper crossbeam assembly 10. Furthermore, since the middle dimension of the upper crossbeam assembly 10 is smaller than the dimension of the overlapping joints at both ends of the upper crossbeam assembly 10, the space occupied by the upper crossbeam assembly 10 in the vehicle can be reduced, thereby improving space utilization.
