[0026] In this embodiment, since the first clamping portion 22 is hinged to the fixing device 4, the first clamping portion 22 can increase or decrease the distance between the first clamping portion 22 and the first supporting portion 21 when rotating relative to the fixing device 4, thereby opening or closing the first fastener 2, and the second clamping portion 32 is hinged to the fixing device 4, so that the second clamping portion 32 can increase or decrease the distance between the second clamping portion 32 and the second supporting portion 31 when rotating relative to the fixing device 4, thereby opening or closing the second fastener 3. Therefore, the spare tire beam welding device of the vehicle can fasten the spare tire beam 1 in the first fastener 2 and the second fastener 3 to realize the welding of the spare tire beam 1; at the same time, the first positioning portion 23 is provided with a first positioning groove 201, and the second positioning portion 33 is provided with a second positioning groove 301.

[0027] For example, the first direction m is the length direction of the spare tire beam 1 .

[0028] It should be understood that when the first fastener 2 and the second fastener 3 are opened, the spare tire beam 1 can be placed in the first fastener 2 and the second fastener 3 for clamping, or the spare tire beam 1 can be taken out from the first fastener 2 and the second fastener 3 after the welding of the spare tire beam 1 is completed; when the first fastener 2 and the second fastener 3 are closed, the spare tire beam 1 is fastened in the first fastener 2 and the second fastener 3, that is, the spare tire beam 1 is located between the first clamping portion 22 and the first supporting portion 21, and between the second clamping portion 32 and the second supporting portion 31, so as to realize the welding of the spare tire beam 1.

[0029] Combination Figure 5 and Figure 6 As shown, the first positioning portion 23 and the second positioning portion 33 both include a first limiting plate a, a second limiting plate b and a third limiting plate c. The first limiting plate a and the third limiting plate c are connected one by one to two opposite sides of the second limiting plate b to form a "U"-shaped structure. The second limiting plate b of the first positioning portion 23 is connected to the first supporting portion 21, and the second limiting plate b of the second positioning portion 33 is connected to the second supporting portion 31.

[0030] In this embodiment, the first positioning portion 23 and the second positioning portion 33 are both "U"-shaped structures, and the first limiting plate a, the second limiting plate b and the third limiting plate c form a corresponding first positioning groove 201 or a second positioning groove 301 to limit the movement of the spare tire beam 1 to avoid affecting the welding of the spare tire beam 1. In addition, the second limiting plate b can also support the spare tire beam 1 to ensure the stability of the welding of the spare tire beam 1.

[0031] In this embodiment, combined with Figure 1 As shown, the frame assembly of the vehicle includes a spare tire beam 1, a first longitudinal beam 5 and a second longitudinal beam 6. The first longitudinal beam 5 and the second longitudinal beam 6 are arranged opposite to each other along a first direction m. The first fastener 2 is closer to the second longitudinal beam 6 than the first longitudinal beam 5. The spare tire beam 1 is connected between the first longitudinal beam 5 and the second longitudinal beam 6. The first longitudinal beam 5 and the second longitudinal beam 6 are both "rectangular" structures, and are welded together by buckling and welding the inner plate and the outer plate arranged opposite to each other along the first direction m. The first longitudinal beam 5 and the second longitudinal beam 6 are fixed by a special jig to facilitate connection with the spare tire beam 1.

[0032] Furthermore, the first longitudinal beam 5 and the second longitudinal beam 6 each include an upper wing surface d, a lower wing surface, an inner ventral surface e and an outer ventral surface, the upper wing surface d and the lower wing surface are arranged opposite to each other, and the inner ventral surface e and the outer ventral surface are arranged opposite to each other along the first direction m.

[0033] In this embodiment, combined with Figure 1As shown, the spare tire beam 1 includes a first upper plate 11, a lower plate 12, and a second upper plate 13. The first upper plate 11 is spaced a certain distance from the second upper plate 13. The lower plate 12 is arranged opposite to the first upper plate 11 and the second upper plate 13, and is connected to the first upper plate 11 and the second upper plate 13. The first upper plate 11, the lower plate 12, and the second upper plate 13 are all located between the first longitudinal beam 5 and the second longitudinal beam 6.

[0034] It should be understood that the first upper plate 11 and the second upper plate 13 are spaced a certain distance apart, which can not only reduce the weight of the spare tire beam 1 to reduce the weight of the frame assembly, but also reduce the welding area of ​​the spare tire beam 1 to improve the welding efficiency of the spare tire beam 1.

[0035] In this embodiment, combined with Figure 1 As shown, when the spare tire beam 1 is fastened to the first fastener 2 and the second fastener 3 , the lower plate 12 is connected to the first supporting portion 21 and the second supporting portion 31 , the first upper plate 11 is connected to the first clamping portion 22 , and the second upper plate 13 is connected to the second clamping portion 32 .

[0036] Combination Figure 1 and Figure 6 As shown, the first supporting portion 21 includes a first positioning pin 211, a second positioning pin 212 and a first insert 213.

The first insert 213 is connected to the fixing device 4 and the first positioning portion 23; wherein the first positioning pin 211 and the second positioning pin 212 are both used to position the spare tire beam 1.

[0037] In this embodiment, the first positioning pin 211 and the second positioning pin 212 can realize accurate positioning of the lower plate 12 and the first upper plate 11 of the spare tire beam 1, avoiding the problem of misalignment. The first insert 213 is connected to the fixing device 4, and the first insert 213 can provide a stable base for the first positioning pin 211 and the second positioning pin 212 to ensure the positioning effect of the first positioning pin 211 and the second positioning pin 212 on the spare tire beam 1; at the same time, it can also play a role in strengthening support for the side of the lower plate 12 close to the first longitudinal beam 5, so as to ensure the normal welding of the spare tire beam 1.

[0038] Specifically, the first positioning pin 211, as the main positioning pin of the first fastener 2, can pass through the side of the lower plate 12 close to the first longitudinal beam 5 and the first upper plate 11 at the same time; the second positioning pin 212, as the auxiliary positioning pin of the first fastener 2, can pass through the side of the lower plate 12 close to the first longitudinal beam 5. Through the cooperation of the first positioning pin 211 and the second positioning pin 212, the side of the lower plate 12 close to the first longitudinal beam 5 and the first upper plate 11 are precisely positioned.

[0039] Combination Figure 1 and Figure 5 As shown, the second supporting portion 31 includes a third positioning pin 311, a fourth positioning pin 312 and a second insert 313, the third positioning pin 311 is connected to the fourth positioning pin 312, the fourth positioning pin 312 is connected to the second insert 313, and the second insert 313 is connected to the fixing device 4 and the second positioning portion 33; wherein the third positioning pin 311 and the fourth positioning pin 312 are both used to position the spare tire beam 1.

[0040] In this embodiment, the third locating pin 311 and the fourth locating pin 312 can realize accurate positioning of the lower plate 12 and the second upper plate 13 of the spare tire beam 1, avoiding the problem of misalignment. The second insert 313 is connected to the fixing device 4, and the second insert 313 can provide a stable base for the third locating pin 311 and the fourth locating pin 312 to ensure the positioning of the spare tire beam 1 by the third locating pin 311 and the fourth locating pin 312; at the same time, it can also play a role in strengthening support for the side of the lower plate 12 close to the second longitudinal beam 6, so as to ensure the normal welding of the spare tire beam 1.

[0041] Specifically, the third positioning pin 311 can pass through the second upper plate 13, and the fourth positioning pin 312 can pass through the side of the lower plate 12 close to the second longitudinal beam 6. Through the cooperation of the third positioning pin 311 and the fourth positioning pin 312, precise positioning of the side of the lower plate 12 close to the second longitudinal beam 6 and the second upper plate 13 can be achieved.

[0042] In this embodiment, combined with Figure 1 and Figure 5 As shown, the diameter of the third positioning pin 311 is smaller than the diameter of the fourth positioning pin 312 , so that the lower plate 12 can be installed in the second fastener 3 through the third positioning pin 311 and the fourth positioning pin 312 in sequence to achieve positioning installation of the lower plate 12 .

[0043] It should be understood that when the spare tire beam 1 is placed into the second fastener 3, the lower plate 12 will be placed into the second fastener 3 before the second upper plate 13, so that the lower plate 12 needs to pass through the third positioning pin 311 and the fourth positioning pin 312 in sequence, and be connected to the fourth positioning pin 312 and the second insert 313. Therefore, the diameter of the third positioning pin 311 should be smaller than the diameter of the fourth positioning pin 312, so that the lower plate 12 can pass through the third positioning pin 311 and be positioned in the second fastener 3 by the fourth positioning pin 312, thereby realizing the welding of the spare tire beam 1.

[0050] Furthermore, combined with Figure 1 As shown, the first support portion 42 and the second support portion 43 are both provided with an avoidance notch 401 to avoid the corresponding first cylinder 24 or second cylinder 34 .

The first support plate g and the third support plate i can reinforce the second support plate h to ensure the stability of the connection between the second support plate h and the first fastener 2 or the second fastener 3, and avoid affecting the welding of the spare tire beam 1.

[0054] Furthermore, the first support plate g and the third support plate i are both located in the middle position of the second support plate h and are vertically connected to the second support plate h, which can better strengthen the second support plate h and ensure that the first support portion 42 can provide a stable and reliable support base for the first fastener 2, and the second support portion 43 can provide a stable and reliable support base for the second fastener 3.
