[0012] In some embodiments, the outer plate of the upper longitudinal beam is slidably connected to the inner plate of the upper longitudinal beam, so that the outer plate of the upper longitudinal beam can drive the adjusting member to move relative to the inner plate of the upper longitudinal beam in the direction from the mating surface to the adjusting member.

[0036] To address the aforementioned issues, this application provides an upper longitudinal beam assembly 2, which includes an inner upper longitudinal beam plate 10, an outer upper longitudinal beam plate 20, and a positioning assembly 40. The outer upper longitudinal beam plate 20 is connected to the inner upper longitudinal beam plate 10 and forms a cavity 30 with the inner upper longitudinal beam plate 10. The outer upper longitudinal beam plate 20 has a mating surface 21 on the side away from the cavity 30. The positioning assembly 40 includes an adjusting member 41, which is disposed on the mating surface 21. The adjusting member 41 has a first positioning hole 411 in the direction from the adjusting member 41 to the mating surface 21. The adjusting member 41 is movable along the mating surface 21 so that the first positioning hole 411 is connected to a positioning fixture.
[0037] The outer plate 20 of the upper longitudinal beam and the inner plate 10 of the upper longitudinal beam cooperate to form a cavity 30, thereby absorbing collision energy and improving the structural strength of the upper longitudinal beam assembly 2. Exemplarily, the inner plate 10 and the outer plate 20 of the upper longitudinal beam can be interlocked to form the cavity 30. Specifically, in the direction perpendicular to the inner plate 10 to the outer plate 20 of the upper longitudinal beam, one cross section of the inner plate 10 can be approximately "L"-shaped, and one cross section of the outer plate 20 can be approximately "inverted L"-shaped. The cavity 30 can be formed by the inner plate 10 and the outer plate 20 of the upper longitudinal beam being relatively close and interlocked. The outer plate 20 of the upper longitudinal beam has a mating surface 21 on the side away from the cavity 30. An adjusting member 41 is disposed on the mating surface 21. The mating surface 21 guides the adjusting member 41 to move in the direction extending from the mating surface 21. It is understood that during the movement of the adjusting member 41 along the mating surface 21, the first positioning hole 411 can also move in the direction extending from the mating surface 21, thus facilitating the movement of the first positioning hole 411 to the position corresponding to the positioning fixture and its connection with the positioning fixture. It should be noted that the positioning fixture is used to determine the specific position of the adjusting member 41 relative to the mating surface 21. Different specifications of positioning fixtures can correspond to different positions on the mating surface 21. The position of the adjusting member 41 on the mating surface 21 can be adjusted to match the first positioning hole 411 with the positioning fixture. After the position of the adjusting member 41 is determined by the positioning fixture, the adjusting member 41 can be fixedly connected to the mating surface 21, for example, by welding, thereby fixing the relative position of the adjusting member 41 and the outer plate 20 of the upper longitudinal beam. This facilitates the positioning and assembly of the upper longitudinal beam assembly 2 through the fixed first positioning hole 411. It is understandable that adjusting the adjusting member 41 facilitates the matching of the upper longitudinal beam assembly 2 with different actual positioning requirements, thereby improving the adjustment flexibility and assembly consistency of the upper longitudinal beam assembly 2. In some application scenarios, the positioning fixture can be connected to the first positioning hole 411 via a positioning post. For example, the positioning post can be inserted into the first positioning hole 411, thereby fixing the adjusting member 41 to the positioning fixture.
[0038] Through the above implementation method, the first positioning hole 411 is used to connect with the positioning fixture. By moving the adjusting member 41 along the mating surface 21, the relative position of the first positioning hole 411 and the outer plate 20 of the upper longitudinal beam can be adjusted, thereby facilitating the adjustment of the relative position of the positioning fixture and the outer plate 20 of the upper longitudinal beam in the extension direction of the mating surface 21, and improving the adjustment flexibility of the upper longitudinal beam assembly 2.
[0039] In some embodiments, the outer plate of the upper longitudinal beam 20 has a second positioning hole 211 that penetrates the mating surface 21 and the surface of the outer plate of the upper longitudinal beam 20 facing away from the mating surface 21. The second positioning hole 211 communicates with the first positioning hole 411, and the radial dimension of the second positioning hole 211 is greater than the radial dimension of the first positioning hole 411. The second positioning hole 211 is used to avoid the positioning fixture. It is understandable that during the movement of the adjusting member 41 along the direction extending from the mating surface 21, the first positioning hole 411 and the second positioning hole 211 also move relative to each other. The positioning fixture can be connected to the first positioning hole 411 and the second positioning hole 211 simultaneously. Specifically, the positioning fixture may have a positioning post, which can be inserted into the first positioning hole 411 and the second positioning hole 211 in sequence. It is understandable that the radial dimension of the second positioning hole 211 is larger than that of the first positioning hole 411. When the positioning post and the first positioning hole 411 are relatively fixed, the positioning post can move within the second positioning hole 211 so that the adjusting member 41 can adjust its position, thereby reducing the difficulty of connecting the positioning fixture and the adjusting member 41. It should be noted that when the positioning fixture is connected to both the first positioning hole 411 and the second positioning hole 211, the orthographic projection of the first positioning hole 411 on the mating surface 21 coincides with the second positioning hole 211. The second positioning hole 211 can also limit the adjustable range of the first positioning hole 411 by its radial dimension in conjunction with the positioning fixture, thereby facilitating the matching of the positioning fixture and the adjusting part 41 and improving production efficiency.
[0040] In some embodiments, the positioning component 40 further includes a limiting bracket 42 disposed on the mating surface 21, forming a limiting space 43 between the limiting bracket 42 and the mating surface 21. The adjusting member 41 is located within the limiting space 43 and can move along the mating surface 21 within the limiting space 43. The shape of the limiting bracket 42 can be any shape, including but not limited to circles, squares, irregular shapes, etc. It is understood that the movement range of the adjusting member 41 on the mating surface 21 can be limited by the limiting space 43. For example, the adjusting member 41 can move along a portion of the mating surface 21 exposed within the limiting space 43. When it moves to the boundary of the limiting space 43, the limiting bracket 42 contacts the adjusting member 41 and prevents the adjusting member 41 from moving to the portion of the mating surface 21 outside the limiting space 43, thereby limiting the movement range of the adjusting member 41 on the mating surface 21. The limiting bracket 42 is fixedly connected to the mating surface 21. For example, the connection method between the limiting bracket 42 and the mating surface 21 can include but is not limited to bolt connection, welding, adhesive bonding, etc. Therefore, the adjustable range of the adjusting component 41 can be limited by the limiting bracket 42, which facilitates the matching efficiency between the positioning fixture and the adjusting component 41, thereby improving production efficiency.
[0041] In some embodiments, a clearance opening 421 is provided on the side of the limiting bracket 42 away from the mating surface 21. The opening size of the clearance opening 421 is smaller than the radial dimension of the adjusting member 41 in the first positioning hole 411. The clearance opening 421 is used to avoid the positioning fixture, so that the adjusting member 41 can be connected to the positioning fixture through the clearance opening 421. For example, the positioning fixture may have a positioning post, which can enter the limiting space 43 through the clearance opening 421 and be inserted into the first positioning hole 411. It is understood that the opening size of the clearance opening 421 is smaller than the radial dimension of the adjusting member 41 in the first positioning hole 411, so that the adjusting member 41 will not exit the limiting space 43 through the clearance opening 421. Thus, by providing a clearance opening 421 on the side of the limiting bracket 42 away from the mating surface 21 and reasonably setting the opening size of the clearance opening 421, it is convenient for the positioning fixture to connect with the adjusting member 41, while reducing the risk of the adjusting member 41 leaving the limiting space 43 through the clearance opening 421.
[0042] In some embodiments, the limiting bracket 42 includes a main body 422 and a connecting part 423. The main body 422 is used to cooperate with the mating surface 21 to form a limiting space 43. The connecting part 423 is connected to both the main body 422 and the mating surface 21. The connecting part 423 can be fixedly connected to the mating surface 21. Exemplarily, the connection method between the connecting part 423 and the mating surface 21 can include, but is not limited to, welding, bolting, gluing, etc. The number of connecting parts 423 can be one, two, or more. Taking two connecting parts 423 as an example, the two connecting parts 423 can be located on both sides of the main body 422, and the two connecting parts 423 can be welded to the mating surface 21. Thus, the main body 422 can be connected to the mating surface 21 through the connecting surface, thereby improving the connection stability between the limiting bracket 42 and the mating surface 21.
[0043] In some embodiments, the inner wall of the limiting bracket 42 is provided with at least one pair of limiting surfaces 424 arranged opposite to each other along the radial direction of the first positioning hole 411, and the adjusting member 41 is located between the at least one pair of limiting surfaces 424. For example, taking a square-shaped limiting bracket 42 as an example, the limiting bracket 42 may have two pairs of limiting surfaces 424, with two of the limiting surfaces 424 in each pair arranged at intervals opposite to each other along the radial direction of the first positioning hole 411, and the adjusting member 41 simultaneously located between the two pairs of limiting surfaces 424. Thus, the movement range of the adjusting member 41 can be limited by at least one pair of limiting surfaces 424, thereby facilitating the improvement of the matching efficiency between the positioning fixture and the adjusting member 41, thereby improving production efficiency, while reducing the risk of the adjusting member 41 detaching from the limiting space 43.
[0044] In some embodiments, the interval between a pair of opposing limiting surfaces 424 is greater than the width of the adjusting member 41 in the interval direction of the pair of opposing limiting surfaces 424, and the difference between the interval and the width is greater than or equal to 1.5 mm and less than or equal to 2.5 mm. Exemplarily, the difference between the interval and the width can be between 1.5 mm and 2 mm, or between 2 mm and 2.5 mm, etc. Specifically, the difference between the interval and the width can be, but is not limited to, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.4 mm, 2.5 mm, etc. Optionally, the difference between the interval and the width is 2 mm. Therefore, by reasonably setting the difference between the interval and the width, the adjusting member 41 can move within the limiting range, while appropriately limiting the movable range of the adjusting member 41, thereby improving the matching efficiency between the positioning fixture and the adjusting member 41 and increasing production efficiency.
[0045] In some embodiments, the outer plate 20 of the upper longitudinal beam is slidably connected to the inner plate 10 of the upper longitudinal beam, so that the outer plate 20 can drive the adjusting member 41 to move relative to the inner plate 10 of the upper longitudinal beam in the direction from the mating surface 21 to the adjusting member 41. Specifically, the outer plate 20 of the upper longitudinal beam can slide with the inner plate 10 of the upper longitudinal beam in the direction from the mating surface 21 to the adjusting member 41, so that the mating surface 21 can move relative to the inner plate 10 of the upper longitudinal beam in the direction from the mating surface 21 to the adjusting member 41. This allows the mating surface 21 to drive the adjusting member 41 to move relative to the inner plate 10 of the upper longitudinal beam, further increasing the adjustable direction of the adjusting member 41. Thus, the adjusting member 41 can be moved and adjusted in the direction extending from the mating surface 21, and also in the direction from the mating surface 21 to the adjusting member 41. Therefore, the positioning component 40 can greatly increase the assembly flexibility of the upper longitudinal beam assembly 2, improve production efficiency, and at the same time, the structure is simple and the cost is low. It should be noted that the inner plate 10 of the upper longitudinal beam can be connected and fixed to other vehicle 1 components. After adjusting the outer plate 20 of the upper longitudinal beam to the corresponding position along the direction from the mating surface 21 to the adjusting member 41, the outer plate 20 of the upper longitudinal beam and the inner plate 10 of the upper longitudinal beam can be fixedly connected in the subsequent assembly process. This can be done by, but is not limited to, welding the outer plate 20 of the upper longitudinal beam to the inner plate 10 of the upper longitudinal beam, etc., so as to fix the relative position of the adjusting member 41 and the inner plate 10 of the upper longitudinal beam, thereby facilitating the positioning and assembly of the upper longitudinal beam assembly 2 through the fixed first positioning hole 411.
[0046] In some embodiments, the number of positioning components 40 is at least two, and the at least two positioning components 40 are spaced apart on the mating surface 21. The number of positioning components 40 can be two, three or more. Taking the number of positioning components 40 as an example, the two positioning components 40 can be located at opposite ends of the mating surface 21, and the positioning fixture can be fixedly connected to the two positioning components 40 at the same time, thereby improving positioning efficiency and accuracy.
[0047] In summary, the upper longitudinal beam assembly 2 provided in this application includes an inner upper longitudinal beam plate 10, an outer upper longitudinal beam plate 20, and a positioning assembly 40. The outer upper longitudinal beam plate 20 is connected to the inner upper longitudinal beam plate 10 and forms a cavity 30 with the inner upper longitudinal beam plate 10. The outer upper longitudinal beam plate 20 has a mating surface 21 on the side away from the cavity 30. The positioning assembly 40 includes an adjusting member 41, which is disposed on the mating surface 21. The adjusting member 41 has a first positioning hole 411 in the direction from the adjusting member 41 to the mating surface 21. The adjusting member 41 can move along the mating surface 21 to connect the first positioning hole 411 with the positioning fixture. Through the above embodiment, the first positioning hole 411 is used to connect with the positioning fixture. By moving the adjusting member 41 along the mating surface 21, the relative position of the first positioning hole 411 and the outer upper longitudinal beam plate 20 can be adjusted, thereby facilitating the adjustment of the relative position of the positioning fixture and the outer upper longitudinal beam plate 20 in the extension direction of the mating surface 21 and improving the adjustment flexibility of the upper longitudinal beam assembly 2.
