The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end.

To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.
[0030] The front cabin front beam assembly 100 according to the first aspect embodiment of the present utility model will be described below with reference to the drawings.
[0031] As Figures 1 to 4As shown in the figure, the front cabin front beam assembly 100 according to the first aspect embodiment of the present utility model includes: a front cross beam 1 and an upper longitudinal beam 2. The front cross beam 1 includes a front cross beam body 11 and a first connecting plate 12 provided at the end of the front cross beam body 11 in the length direction. The upper longitudinal beam 2 is connected to one end of the front cross beam 1 in the length direction and includes an upper longitudinal beam body 21 and a second connecting plate 22 provided at one end of the upper longitudinal beam body 21 close to the front cross beam 1. The first connecting plate 12 and the second connecting plate 22 are respectively connected to the upper longitudinal beam body 21 and the front cross beam body 11.
[0032] That is to say, the connection between the front cross beam 1 and the upper longitudinal beam 2 is realized through the connection between the first connecting plate 12 and the upper longitudinal beam body 21 and the connection between the second connecting plate 22 and the front cross beam body 11, so as to realize the connection between the front cross beam 1 and the upper longitudinal beam 2. That is, there are at least two connecting structures at the connection position between the front cross beam 1 and the upper longitudinal beam 2, which can increase the connection position between the front cross beam 1 and the upper longitudinal beam 2 to improve the stiffness at the connection between the front cross beam 1 and the upper longitudinal beam 2. It can be understood that the front cross beam 1 can be connected to the A-pillar side surround structure located behind the front cross beam 1 through the upper longitudinal beam 2, so as to form a continuous and high-strength force transmission path between the front cross beam 1 and the A-pillar side surround structure. Thus, the force at the front cross beam 1 can be transmitted and dispersed to the rear A-pillar side surround structure through the upper longitudinal beam 2, and the deformation amplitude of the front cross beam 1 when it is collided can be reduced to improve the collision performance of the front cabin front beam assembly 100.
[0033] For the front cabin front beam assembly 100 according to the first aspect embodiment of the present utility model, through the connection between the first connecting plate 12 and the upper longitudinal beam body 21 and the connection between the second connecting plate 22 and the front cross beam body 11, the connection position between the front cross beam 1 and the upper longitudinal beam 2 can be increased, and the stiffness at the connection between the front cross beam 1 and the upper longitudinal beam 2 can be improved. Thus, the deformation amplitude of the front cross beam 1 when it is collided can be reduced to improve the collision performance of the front cabin front beam assembly 100.
[0034] According to some embodiments of the present utility model, the first connecting plate 12 and the second connecting plate 22 are arranged opposite to each other in the front-rear direction. The first connecting plate 12 is connected to one of the front side wall and the rear side wall of the front crossbeam body 11 and the upper longitudinal beam body 21, and the second connecting plate 22 is connected to the other of the front side wall and the rear side wall of the front crossbeam body 11 and the upper longitudinal beam body 21. That is to say, the first connecting plate 12 and the second connecting plate 22 are at least used to connect the front side wall and the rear side wall of the front crossbeam body 11 and the upper longitudinal beam body 21 together. It can be understood that the dimension of the front crossbeam body 11 in the up-down direction, that is, the height dimension, is usually larger than the dimension in the front-rear direction, that is, the thickness dimension, so that the front side wall and the rear side wall of the front crossbeam body 11 have a larger area, thereby providing a larger connection area for the first connecting plate 12 and the second connecting plate 22, and thus increasing the connection positions of the first connecting plate 12 and the second connecting plate 22 with the front crossbeam body 11 and the upper longitudinal beam body 21 to improve the connection strength. In addition, when the front crossbeam body 11 bears a front-side collision, the collision will generate a backward impact on the front crossbeam body 11. Among them, the front side surface of the front crossbeam body 11 is the directly stressed position. Therefore, by connecting the front side wall and the rear side wall of the front crossbeam body 11 and the upper longitudinal beam body 21 through the first connecting plate 12 and the second connecting plate 22, the anti-deformation strength of the front side wall and the rear side wall of the front crossbeam body 11 in the front-rear direction can be better improved, so as to reduce the deformation amplitude of the front crossbeam body 11 after bearing the collision, thereby improving the collision performance of the front cabin front beam assembly 100.
[0035] It should be noted that it can be that the first connecting plate 12 is connected to the front side wall of the front crossbeam body 11 and the front side wall of the upper longitudinal beam body 21, and the second connecting plate 22 is connected to the rear side wall of the front crossbeam body 11 and the rear side wall of the upper longitudinal beam body 21; it can also be that the second connecting plate 22 is connected to the front side wall of the front crossbeam body 11 and the front side wall of the upper longitudinal beam body 21, and the first connecting plate 12 is connected to the rear side wall of the front crossbeam body 11 and the rear side wall of the upper longitudinal beam body 21, and no specific limitation is made here.
[0036] According to some embodiments of the present utility model, the first connecting plate 12 is lapped on the outer side of one end of the upper longitudinal beam body 21 close to the front cross beam 1, and the connecting position of the first connecting plate 12 and the upper longitudinal beam body 21 is located at the lapping position of the first connecting plate 12 and the upper longitudinal beam body 21; the second connecting plate 22 is lapped on the outer side of the end of the front cross beam body 11 in the length direction, and the connecting position of the second connecting plate 22 and the front cross beam body 11 is located at the lapping position of the second connecting plate 22 and the front cross beam body 11. Wherein, the lapping position of the first connecting plate 12 and the upper longitudinal beam body 21 can provide a larger connecting space for the connection between the first connecting plate 12 and the upper longitudinal beam body 21, and the lapping position of the second connecting plate 22 and the front cross beam body 11 can provide a larger connecting space for the connection between the second connecting plate 22 and the front cross beam body 11, thereby reducing the connection difficulty between the first connecting plate 12 and the upper longitudinal beam body 21 and between the second connecting plate 22 and the front cross beam body 11.
[0037] According to some embodiments of the present utility model, the first connecting plate 12 is located on the front side of the second connecting plate 22, and a through assembly hole 111 is formed on the front side surface of the front cross beam 1, and the assembly hole 111 is opposite to the connecting position of the second connecting plate 22 and the front cross beam body 11. That is to say, the connecting position of the second connecting plate 22 and the front cross beam body 11 can be observed and operated through the assembly hole 111 on the front side surface of the front cross beam 1. For example, when the second connecting plate 22 and the front cross beam body 11 are connected by bolts, on the front side of the front cross beam body 11, the bolts can be put into the front cross beam body 11 through the assembly hole 111 and passed through the set connecting position of the front cross beam body 11 and the second connecting plate 22, thereby avoiding the increase in installation and disassembly difficulty caused by inconvenient operation when fixing the second connecting plate 22 and the front cross beam body 11 from the back side of the front cross beam body 11. Thus, a larger operation space can be provided for the connection between the second connecting plate 22 and the front cross beam body 11 to reduce the connection difficulty between the second connecting plate 22 and the front cross beam body 11, thereby improving the assembly efficiency of the front cross beam 1 and the upper longitudinal beam 2.
[0038] It should be noted that here is only an example of the positional relationship between one first connecting plate 12 and the second connecting plate 22 for the convenience of understanding the function of the assembly hole 111, and it is not a limitation on the relative positions of the first connecting plate 12 and the second connecting plate 22. For example, the first connecting plate 12 can also be located on the rear side of the second connecting plate 22, etc., which will not be elaborated here.
[0039] In a specific example, a first connection hole penetrating in the front-rear direction is formed in the first connection plate 12, a second connection hole penetrating in the front-rear direction is formed in the front side wall of the upper longitudinal beam body 21, the first connection hole and the second connection hole are oppositely arranged, and a bolt fastener is inserted through the first connection hole and the second connection hole to fix the first connection plate 12 on the upper longitudinal beam body 21. A third connection hole penetrating in the front-rear direction is formed in the rear side wall of the front cross beam body 11, a fourth connection hole penetrating in the front-rear direction is formed in the second connection plate 22, the third connection hole and the fourth connection hole are oppositely arranged, and the bolt fastener can be inserted through the third connection hole and the fourth connection hole through the assembly hole 111 to fix the second connection plate 22 on the rear side wall of the front cross beam body 11. In addition, a plurality of first connection holes, second connection holes, third connection holes and fourth connection holes are all arranged at intervals in the up-down direction to improve the connection strength between the front cross beam 1 and the upper longitudinal beam 2.
[0040] According to some embodiments of the present invention, a first cavity 112 is formed in the front cross beam body 11, a second cavity 211 is formed in the upper longitudinal beam body 21, and the first connection plate 12 and the second connection plate 22 define a communication cavity 3 communicating the first cavity 112 and the second cavity 211. Therefore, by communicating the first cavity 112 and the second cavity 211 through the communication cavity 3, a stable and continuous force transmission path can be formed between the front cross beam body 11 and the upper longitudinal beam body 21, so as to ensure that the impact force borne by the front cross beam body 11 can be stably transmitted to the rear body structure through the upper longitudinal beam 2, so as to reduce the deformation amplitude of the front cross beam body 11 and be beneficial to improving the collision performance of the front cabin front beam assembly 100.
[0041] In a specific example, the cross section of the front cross beam body 11 is in a "B" shape, and the first cavity 112 includes a first sub-cavity 1121 and a second sub-cavity 1122 arranged at intervals in the up-down direction. Therefore, the bending resistance and torsional resistance of the front cross beam body 11 can be improved, and at the same time, the front cross beam body 11 can effectively absorb most of the energy of a frontal collision, so as to improve the collision performance of the front cabin front beam assembly 100.
[0042] According to some embodiments of the present invention, the outer peripheral contour of the cross section of the communication cavity 3 is formed into a closed ring shape. That is to say, in the outer peripheral direction of the connection cavity, the first connection plate 12 and the second connection plate 22 are connected into a closed-loop structure to improve the stiffness at the connection position between the front cross beam 1 and the upper longitudinal beam 2.
[0043] In a specific example, the cross-section of the first connecting plate 12 is in a "concave" shape that opens towards the upper longitudinal beam body 21, that is, the first connecting plate 12 can surround at least a part of the upper and lower sides of the upper longitudinal beam body 21. The cross-section of the second connecting plate 22 is in a "concave" shape that opens towards the front crossbeam body 11, that is, the second connecting plate 22 can surround at least a part of the upper and lower sides of the front crossbeam body 11. Thus, a closed-loop structure can be formed through two "concave" shaped structures with opposite openings, so as to improve the stiffness at the connection of the front crossbeam 1 and the upper longitudinal beam 2.
[0044] According to some embodiments of the present invention, the first connecting plate 12 and the front crossbeam body 11 are independently formed. It can be understood that, compared with the front crossbeam 1, the structures of both the first connecting plate 12 and the front crossbeam body 11 are relatively simple, and the production and processing difficulty is lower. Therefore, independently forming the first connecting plate 12 and the front crossbeam body 11 can reduce the production and processing difficulty of the first connecting plate 12 and the front crossbeam body 11, and can meet the requirements of the complex shape of the front crossbeam body 11. In a specific example, the first connecting plate 12 is welded to the end of the front crossbeam body 11 in the length direction to improve the stiffness at the connection of the first connecting plate 12 and the front crossbeam body 11.
[0045] In a specific example, the front crossbeam 1 further includes a pair of front fascia lock brackets 13 and a pair of front bumper limit plates 14 provided on the front crossbeam body 11. The front fascia lock brackets 13 are used to fix the front fascia, and the front bumper limit plates 14 are used to limit the front bumper to improve the stability after the front bumper is installed. Among them, the two front fascia lock brackets 13 and the two front bumper limit plates 14 are welded to the front crossbeam body 11 to improve the connection strength between the front fascia lock brackets 13 and the front bumper limit plates 14 and the front crossbeam body 11. In addition, the two front fascia lock brackets 13 are symmetrically distributed in the left-right direction, and the two front bumper limit plates 14 are symmetrically distributed in the left-right direction.
[0046] According to some embodiments of the present invention, the upper longitudinal beam body 21 and the second connecting plate 22 are integrally formed. Thus, integral forming can improve the connection strength between the upper longitudinal beam body 21 and the second connecting plate 22, and at the same time, the process and connecting parts for connecting the upper longitudinal beam body 21 and the second connecting plate 22 can be omitted, so as to improve the production efficiency of the upper longitudinal beam 2 and reduce the production cost of the upper longitudinal beam 2.
[0047] According to some embodiments of the present invention, the front crossbeam body 11 is a roll-formed part. Among them, the roll-forming process has high production efficiency, high production flexibility and low pollution, so as to improve the production efficiency and shaping flexibility of the front crossbeam body 11, and reduce the emissions and noise pollution generated during the processing of the front crossbeam body 11.
[0048] According to some embodiments of the present utility model, the front crossbeam body 11 is made of high-strength steel. Among them, high-strength steel has high strength, low weight, low cost and high fatigue life. Therefore, using a high-strength steel part as the front crossbeam body 11 can reduce the weight and usage cost of the front crossbeam body 11 while ensuring the strength of the front crossbeam body 11, and is beneficial to extending the service life of the front crossbeam body 11.
[0049] The vehicle according to the second aspect embodiment of the present utility model will be described below with reference to the accompanying drawings.
[0050] The vehicle according to the second aspect embodiment of the present utility model includes: a front cabin front beam assembly 100.
[0051] For the vehicle according to the second aspect embodiment of the present utility model, by connecting the first connecting plate 12 to the upper longitudinal beam body 21 and connecting the second connecting plate 22 to the front crossbeam body 11, the connection positions of the front crossbeam 1 and the upper longitudinal beam 2 can be increased, and the stiffness at the connection of the front crossbeam 1 and the upper longitudinal beam 2 can be improved. Thus, the deformation amplitude of the front crossbeam 1 when it is collided can be reduced, so as to improve the collision performance of the front cabin front beam assembly 100.
[0052] In a specific example, the vehicle is a long-head truck.
