[0038] Reference below Figure 1 A vehicle according to an embodiment of the present invention is described.

[0039] like Figure 1 As shown, the vehicle according to the utility model includes: a frame 1, the frame 1 includes a mounting crossbeam 11 and two longitudinal beams 12, the mounting crossbeam 11 is connected between the two longitudinal beams 12, the mounting crossbeam 11 is fixed with a plurality of first mounting brackets 111, the plurality of first mounting brackets 111 are arranged along the length direction of the mounting crossbeam 11, the two longitudinal beams 12 are respectively fixed with a second mounting bracket 121 and a third mounting bracket 122, along the length direction of the vehicle, the second mounting bracket 121 and the third mounting bracket 122 are both located at the front side of the mounting crossbeam 11; a battery pack 2, the battery pack 2 is located below the frame 1, and the battery pack 2 is fixedly connected to the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122.

[0040] The vehicle includes a frame 1, which can support the vehicle structure and bear the vehicle load, so that the vehicle can drive smoothly and safely. The frame 1 includes a mounting crossbeam 11 and two longitudinal beams 12. The mounting crossbeam 11 is connected between the two longitudinal beams 12. For example, the mounting crossbeam 11 can be connected between the two longitudinal beams 12 by welding, or by bolts, but the present application is not limited thereto. The mounting crossbeam 11 can also be connected between the two longitudinal beams 12 by other means, as long as the mounting crossbeam 11 is connected between the two longitudinal beams 12. The present application takes the mounting crossbeam 11 welded and connected between the two longitudinal beams 12 as an example for explanation, which is conducive to the reliable connection between the mounting crossbeam 11 and the two longitudinal beams 12, so that the frame 1 forms a stable frame structure, thereby improving the stability of the frame 1.

[0041] The mounting crossbeam 11 is fixed with a plurality of first mounting brackets 111, for example, the first mounting bracket 111 can be fixedly connected to the mounting crossbeam 11 by welding, or the first mounting bracket 111 can be fixedly connected to the mounting crossbeam 11 by bolts, but the present application is not limited thereto, and the first mounting bracket 111 can also be fixedly connected to the mounting crossbeam 11 by other means, as long as the mounting crossbeam 11 is fixedly provided with the first mounting bracket 111. The first mounting bracket 111 is provided with a plurality of, for example, the first mounting bracket 111 can be provided with 2, 3 or more, and the present application takes the first mounting bracket 111 provided with 3 as an example for explanation, so as to reduce the risk of the cost of the frame 1 being increased due to too many first mounting brackets 111, and also reduce the risk of cracking when there is only one first mounting bracket 111. The plurality of first mounting brackets 111 are arranged along the length direction of the mounting crossbeam 11, which is conducive to the plurality of first mounting brackets 111 being subjected to force along the length direction of the mounting crossbeam 11, and reduces the risk of stress concentration on one of the first mounting brackets 111, thereby causing the first mounting bracket 111 to break.

[0042] The two longitudinal beams 12 are respectively fixed with a second mounting bracket 121 and a third mounting bracket 122. For example, the second mounting bracket 121 and the third mounting bracket 122 can be fixed to the corresponding longitudinal beam 12 by welding, and the second mounting bracket 121 and the third mounting bracket 122 can also be fixed to the corresponding longitudinal beam 12 by bolts, but the present application is not limited to this. The second mounting bracket 121 and the third mounting bracket 122 can also be fixed to the corresponding longitudinal beam 12 by other means. The present application takes the second mounting bracket 121 and the third mounting bracket 122 being fixed to the corresponding longitudinal beam 12 by welding as an example to improve the stability of the second mounting bracket 121 and the third mounting bracket 122, reduce the risk of breakage at the connection between the second mounting bracket 121, the third mounting bracket 122 and the longitudinal beam 12, thereby improving the overall structural stability of the frame 1.

[0043] Along the length of the vehicle, Figure 1In the X direction, the second mounting bracket 121 and the third mounting bracket 122 are both located on the front side of the mounting crossbeam 11, the battery pack 2 is located below the frame 1, and the battery pack 2 is fixedly connected to the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122. For example, the battery pack 2 and the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122 can be fixedly connected by bolts, and the battery pack 2 and the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122 can also be fixedly connected by welding, but the present application is not limited thereto. The battery pack 2 and the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122 can also be fixedly connected by other The battery pack 2 can be fixedly connected to the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122 by other means. The present application takes the example that the battery pack 2 is fixedly connected to the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122 by bolts, which is beneficial to fix the battery pack 2 to the frame 1 through the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122. Compared with the traditional method of mounting the battery pack on other structures of the vehicle, the working stability of the battery pack 2 can be improved. In addition, fixing the battery pack 2 to the frame 1 by bolts can also facilitate the replacement of the battery pack 2 at a later time, thereby improving the replacement efficiency of the battery pack 2.

[0044] Specifically, the first mounting bracket 111 is welded and fixed to the mounting cross beam 11, the second mounting bracket 121 and the third mounting bracket 122 are respectively welded to the corresponding longitudinal beam 12, and the battery pack 2 is respectively fixedly connected to the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122 by bolts, thereby achieving the battery pack 2 being fixedly connected to the frame 1 through the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122.

[0045] Furthermore, a sixth mounting bracket 4 may be arranged between the battery pack 2 and the first mounting bracket 111. The sixth mounting bracket 4 may be arranged as an "L"-shaped plate. A weight-reducing hole structure may be arranged on the sixth mounting bracket 4, which is beneficial to the lightweight design of the vehicle. The sixth mounting bracket 4 is also beneficial to the fastening connection between the battery pack 2 and the first mounting bracket 111, thereby improving the connection strength between the battery pack 2 and the first mounting bracket 111, and thereby improving the structural stability of the vehicle.

[0046] Therefore, by fixedly connecting the battery pack 2 to the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122, the battery pack 2 can be stably assembled on the frame 1, reducing the length of the stressed cantilever between the battery pack 2 and the frame 1, and reducing the loosening, abnormal noise and cracking problems at the connection between the battery pack 2 and the frame 1.

[0047] In some embodiments of the present invention, Figure 1 As shown, at least two first mounting brackets 111 among the plurality of first mounting brackets 111 have the same structure.

[0048] Among them, the structures of at least two first mounting brackets 111 among the multiple first mounting brackets 111 can be the same, for example: two first mounting brackets 111 among the multiple first mounting brackets 111 have the same structure, or the structures of the multiple first mounting brackets 111 are the same. The present application takes the example of multiple first mounting brackets 111 having the same structure as an example. The same structure of multiple first mounting brackets 111 can reduce the number of molds, thereby reducing mold development costs, and further saving vehicle development cycle and production costs.

[0049] In some embodiments of the present invention, Figure 1 As shown, each first mounting bracket 111 is provided with an error-proofing structure 112 .

[0050] Among them, each first mounting bracket 111 can be provided with an anti-error structure 112, for example: each first mounting bracket 111 can be provided with an anti-error bolt or an anti-error hole. The present application takes the example of each first mounting bracket 111 being provided with an anti-error hole for explanation. Based on the charger layout requirements, the first mounting bracket 111 needs to take into account the charger installation at the same time. The first mounting bracket 111 has different mounting holes. By providing an anti-error structure 112 on each first mounting bracket 111, the risk of incorrect installation of multiple first mounting brackets 111 can be reduced, so that each first mounting bracket 111 can be assembled to the target position.

[0051] In some embodiments of the present invention, Figure 1 As shown, the plurality of first mounting brackets 111 are all located at the rear side of the mounting beam 11 .

[0052] Among them, multiple first mounting brackets 111 can be located on the rear side of the mounting beam 11. Based on the layout requirements of the charger, the first mounting bracket 111 needs to take into account the installation of the battery pack 2 and the charger at the same time. Multiple first mounting brackets 111 are arranged on the rear side of the mounting beam 11 to facilitate the installation of the charger and reduce the risk of interference between the charger and the battery pack 2 and other components assembled on the frame 1, thereby facilitating the smooth installation of the charger and the battery pack 2.

[0053] In some embodiments of the present invention, Figure 1 As shown, the mounting crossbeam 11 has a top wall 113 , a rear side wall 114 and a bottom wall, and the first mounting bracket 111 is connected to the top wall 113 , the rear side wall 114 and the bottom wall.

[0054] The mounting crossbeam 11 may include a top wall 113, a rear side wall 114 and a bottom wall, and the top wall 113, the rear side wall 114 and the bottom wall may be integrally formed to improve the structural strength of the mounting crossbeam 11, thereby improving the structural strength of the frame 1. The first mounting bracket 111 is connected to the top wall 113, the rear side wall 114 and the bottom wall, and the first mounting bracket 111 is overlapped on the top wall 113, the rear side wall 114 and the bottom wall, respectively, to achieve a reliable connection effect between the first mounting bracket 111 and the mounting crossbeam 11.

[0055] Furthermore, the first mounting bracket 111 may include an upper bracket plate 1111 and a lower bracket plate 1112, and the upper bracket plate 1111 and the lower bracket plate 1112 are welded to form the first mounting bracket 111, thereby reducing the risk of the first mounting bracket 111 being cantilevered too long and improving the structural strength of the first mounting bracket 111. The upper bracket plate 1111 and the lower bracket plate 1112 may both have a welding flange 3, and the welding flange 3 of the upper bracket plate 1111 overlaps the top wall 113 and a portion of the rear side wall 114 of the mounting beam 11, and the welding flange 3 of the lower bracket plate 1112 overlaps a portion of the rear side wall 114 and the bottom wall of the mounting beam 11, and the welding flange 3 is connected to the mounting beam 11 by welding, thereby achieving the effect of reliably connecting the first mounting bracket 111 to the mounting beam 11.

[0056] In some embodiments of the present invention, Figure 1 As shown, along the length direction of the mounting beam 11, the connection length dimension between at least one first mounting bracket 111 and the mounting beam 11 is L, which satisfies the relationship: 100mm≤L≤153mm.

[0057] Among them, along the length direction of the mounting beam 11, the connection length dimension of at least one first mounting bracket 111 and the mounting beam 11 is L, and the connection length dimension L between the first mounting bracket 111 and the mounting beam 11 can satisfy the relationship, 100mm≤L≤153mm, for example: the connection length dimension L between the first mounting bracket 111 and the mounting beam 11 can be set to 100mm, 120mm or 153mm, but the present application is not limited to this. The connection length dimension L between the first mounting bracket 111 and the mounting beam 11 can also be set to other lengths, as long as L satisfies the relationship, 100mm≤L≤153mm. The present application takes the connection length dimension L between the first mounting bracket 111 and the mounting beam 11 as 153mm as an example for explanation. Setting the connection length dimension L between the first mounting bracket 111 and the mounting beam 11 to the longest can further improve the structural strength of the first mounting bracket 111, thereby improving the connection reliability between the first mounting bracket 111 and the mounting beam 11.

[0058] In some embodiments of the present invention, Figure 1As shown, the mounting beam 11 is fixedly provided with a fourth mounting bracket 116 and a fifth mounting bracket 117, the fourth mounting bracket 116 and the fifth mounting bracket 117 are located on the front side of the mounting beam 11, the fourth mounting bracket 116 and the fifth mounting bracket 117 are arranged along the length direction of the mounting beam 11, and the fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111 are used to install the charger.

[0059] Among them, the mounting beam 11 can be fixedly provided with a fourth mounting bracket 116 and a fifth mounting bracket 117. For example, the fourth mounting bracket 116 and the fifth mounting bracket 117 can be connected to the mounting beam 11 by welding, and the fourth mounting bracket 116 and the fifth mounting bracket 117 can also be connected to the mounting beam 11 by bolts, but the present application is not limited to this. The fourth mounting bracket 116 and the fifth mounting bracket 117 can also be connected to the mounting beam 11 by other means, as long as the mounting beam 11 is fixedly provided with the fourth mounting bracket 116 and the fifth mounting bracket 117.

[0060] The fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111 are used to install the charger. For example, the charger can be connected to the fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111 by bolts, and the charger can also be connected to the fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111 by welding, but the present application is not limited to this, as long as the fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111 can be used to install the charger.

[0061] Multiple first mounting brackets 111 are located on the rear side of the mounting beam 11, the fourth mounting bracket 116 and the fifth mounting bracket 117 are located on the front side of the mounting beam 11, and the multiple first mounting brackets 111 and the fourth mounting bracket 116 and the fifth mounting bracket 117 are respectively located on both sides of the mounting beam 11, and the fourth mounting bracket 116 and the fifth mounting bracket 117 are arranged along the length direction of the mounting beam 11. Such an arrangement can facilitate the connection between the charger and the fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111, improve the connection reliability between the charger and the fourth mounting bracket 116, the fifth mounting bracket 117 and at least one first mounting bracket 111, reduce the risk of interference between the charger and other components on the frame 1, and thus improve the working stability of the charger.

[0062] In some embodiments of the present invention, Figure 1 As shown, the second mounting bracket 121 is constructed as an integrally formed part, and the second mounting bracket 121 and the corresponding longitudinal beam 12 jointly define a first space 123 with one side open, and the open end of the first space 123 is open toward the inner side of the corresponding longitudinal beam 12 .

[0063] Among them, the second mounting bracket 121 can be constructed as an integrally formed part, which is conducive to improving the structural stability of the second mounting bracket 121 and reducing the risk of cracking of the second mounting bracket 121. The second mounting bracket 121 and the corresponding longitudinal beam 12 jointly define a first space 123 with one side open. The first space 123 can avoid nuts, which is convenient for the battery pack 2 and the second mounting bracket 121 to be assembled by bolts. Along the width direction of the vehicle, the open end of the first space 123 is open to the inner side of the corresponding longitudinal beam 12, reducing the risk of the second mounting bracket 121 scratching the tire or even bursting the tire due to the edge of the open end of the first space 123 facing the tire, thereby improving the driving safety of the vehicle.

[0064] In some embodiments of the present invention, Figure 1 As shown, the third mounting bracket 122 and the corresponding longitudinal beam 12 jointly define a second space with one side open, and the open end of the second space is open toward the inner side of the corresponding longitudinal beam 12 .

[0065] The third mounting bracket 122 and the corresponding longitudinal beam 12 jointly define a second space with one side open, and the second space can avoid nuts, so that the battery pack 2 and the third mounting bracket 122 can be assembled by bolts. Along the width direction of the vehicle, the open end of the second space is open to the inner side of the corresponding longitudinal beam 12, reducing the risk of the third mounting bracket 122 scratching the tire or even causing a tire blowout due to the edge of the open end of the second space facing the tire, thereby improving the driving safety of the vehicle.

[0066] Furthermore, the second mounting bracket 121 and the third mounting bracket 122 can be provided with positioning pin mounting holes. When the second mounting bracket 121 and the third mounting bracket 122 are connected to the battery pack 2, the battery pack 2 is positioned at the correct position of the second mounting bracket 121 and the third mounting bracket 122 by the positioning pins, and then fixedly connected by bolts, thereby reducing the risk of misinstallation of the battery pack 2 and improving the assembly efficiency of the vehicle.

[0068] Among them, due to the asymmetric arrangement of the battery pack 2, the installation point of the battery pack 2 is set on the outside of the longitudinal beam 12 along the width direction of the vehicle, so the third mounting bracket 122 cannot be integrally formed, reducing the risk of the third mounting bracket 122 failing to be formed due to the occurrence of an acute-angle mold. The third mounting bracket 122 may include a first bracket body 1221 and a second bracket body 1222, which are snap-fitted and welded to improve the structural strength of the third mounting bracket 122. The second bracket body 1222 is located below the first bracket body 1221, and the first bracket body 1221 is connected between the second bracket body 1222 and the corresponding longitudinal beam 12. The first bracket body 1221 may have a welding flange 3, and the welding flange 3 of the first bracket body 1221 may contact and weld with a portion of the inner side wall, the bottom wall, and the outer side wall of the longitudinal beam 12, respectively. The welding flange 3 overlaps the inner side wall, the bottom wall, and the outer side wall of the longitudinal beam 12, thereby improving the connection strength between the first bracket body 1221 and the longitudinal beam 12.

[0069] The second bracket body 1222 is connected to the battery pack 2, for example, the second bracket body 1222 and the battery pack 2 can be connected by bolts, or by welding, but the present application is not limited thereto, and the second bracket body 1222 and the battery pack 2 can also be connected by other means, as long as the second bracket body 1222 and the battery pack 2 are connected, so that the battery pack 2 is connected to the longitudinal beam 12 through the first bracket body 1221 and the second bracket body 1222. Further, the battery pack 2 is fixed to the mounting cross beam 11 and the two longitudinal beams 12 through the first mounting bracket 111, the second mounting bracket 121 and the third mounting bracket 122, respectively, and the frame 1 and the battery pack 2 are connected at multiple points, for example, the frame 1 and the battery pack 2 are connected at 5 points, so that the rear section of the vehicle forms a rigid frame, effectively improving the rigidity of the whole vehicle, so that the battery pack 2 is stably assembled on the frame 1, reducing the load cantilever length between the battery pack 2 and the frame 1, and reducing the loosening, abnormal noise and cracking problems at the connection between the battery pack 2 and the frame 1.
