[0031] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Please refer to the following Figure 1-5 A chassis structure 100 according to an embodiment of the present invention is described.

[0033] Reference Figure 1 、 Figure 3 、 Figure 4 and Figure 5 According to an embodiment of the present invention, a chassis structure 100 is applied to a vehicle. The chassis structure 100 includes: a longitudinal beam 10 , a battery pack 20 and a first fastener 31 .

[0034] Specifically, there are two longitudinal beams 10, which extend in the front-to-rear direction of the vehicle and are spaced apart from each other along the left and right sides of the vehicle; the battery pack 20 includes a box body 21, which has a receiving cavity, and a partition beam 22 extending in the left-right direction of the vehicle is provided in the receiving cavity, and a vertical direction (such as Figure 5 The first fastener 31 passes through the connection hole 211 and is connected to the longitudinal beam 10 to fix the battery pack 20 on the longitudinal beam 10.

[0035] For example, Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the longitudinal beam 10 extends in the front-to-back direction, and the two longitudinal beams 10 are arranged at intervals in the front-to-back direction. A accommodating cavity is defined in the box body 21, and a partition beam 22 extending in the left-to-right direction is formed in the accommodating cavity. The partition beam 22 is located in the middle position of the accommodating cavity in the front-to-back direction. The connecting hole 211 passes through the box body 21 and the partition beam 22 in the up-down direction. There are two connecting holes 211, and the two connecting holes 211 are arranged at intervals in the left-to-right direction on the box body 21. The first fastener 31 passes through the connecting hole 211 from bottom to top and is connected to the longitudinal beam 10. There are two first fasteners 31, and each first fastener 31 is connected to the two longitudinal beams 10 respectively.

[0036] When assembling the battery pack 20 and the longitudinal beam 10, first bring the battery pack 20 and the longitudinal beam 10 close together, and then use the first fastener 31 to pass through the connecting hole 211 to fix the battery pack 20 and the longitudinal beam 10. It should be noted that the first fastener 31 on the left passes through the connecting hole 211 on the left to connect with the longitudinal beam 10 on the left, and the first fastener 31 on the right passes through the connecting hole 211 on the right to connect with the longitudinal beam 10 on the right. At this time, the connection between the battery pack 20 and the longitudinal beam 10 is completed.

[0037] The chassis structure 100 of the present invention is provided with a connecting hole 211 on the box body 21. The connecting hole 211 passes through the box body 21 and the partition beam 22 in the up and down directions, thereby ensuring the fixing strength of the battery pack 20 and the longitudinal beam 10, and thus effectively preventing the battery pack 20 from separating from the longitudinal beam 10, and ensuring the reliability of the connection between the battery pack 20 and the longitudinal beam 10. At the same time, this setting form of the connecting hole 211 does not need to consider whether the battery pack 20 and the longitudinal beam 10 can be firmly connected, so the design freedom of the battery pack 20 can be improved, and the size of the battery pack 20 can be designed according to actual needs, thereby improving the storage capacity of the battery pack 20, and thus ensuring the endurance of the vehicle.

[0038] In addition, the connection structure of this battery pack 20 is simple and can effectively improve the integration of the battery pack 20. Compared with the solution of arranging multiple single-pack batteries with each other in the prior art, the chassis structure 100 of the present application can reduce the number of wiring harnesses used, thereby improving the lightweight level of the entire vehicle, reducing vehicle manufacturing costs, and reducing vehicle energy consumption.

[0039] According to the chassis structure 100 of the embodiment of the present invention, a connection hole 211 is provided on the box body 21, thereby ensuring the fixing strength of the battery pack 20 and the longitudinal beam 10 and ensuring the reliability of the connection between the battery pack 20 and the longitudinal beam 10. At the same time, the design freedom of the battery pack 20 can be improved, the storage capacity of the battery pack 20 can be improved, and the lightweight level of the entire vehicle can be improved.

[0040] According to some embodiments of the present invention, referring to Figure 3 、 Figure 4 and Figure 5 The battery pack 20 further includes a connecting post 23, which is passed through and fixed in the connecting hole 211. The connecting post 23 is formed with a vertical direction (such as Figure 5 The through-hole 211 is formed by passing through the connecting post 23 (in the vertical direction shown), and the first fastener 31 is inserted into the through-hole. Thus, the connecting post 23 is provided, and the connecting post 23 and the partition beam 22 cooperate to form the connecting hole 211, thereby eliminating the need for an additional connecting hole 211. Furthermore, the through-hole facilitates the fastening of the first fastener 31 to the longitudinal beam 10, thereby ensuring that the first fastener 31 can be properly connected to the longitudinal beam 10.

[0041] For example, Figure 3 、 Figure 4 and Figure 5 As shown, the connecting column 23 extends in the up-down direction, the connecting column 23 is passed through the partition beam 22, the upper end of the connecting column 23 is connected to the top wall of the box body 21, the lower end of the connecting column 23 is connected to the bottom wall of the box body 21, the upper half of the connecting column 23 is exposed from the partition beam 22, and a through hole is formed in the connecting column 23 that passes through the connecting column 23 in the up-down direction.

[0042] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 5 The battery pack 20 is arranged on the lower side of the longitudinal beam 10 (eg Figure 3 The chassis structure 100 further includes a sealing member 40, which is disposed in the connecting hole 211 and is located at one end of the connecting hole 211 close to the longitudinal beam 10 (as shown in FIG. Figure 5 The sealing member 40 is formed in a ring shape and is used to seal the gap between the inner wall of the connecting hole 211 and the first fastening member 31.

[0043] In this way, the seal 40 can ensure the sealing between the first fastener 31 and the connection hole 211, thereby ensuring the airtightness of the box body 21, and further effectively preventing liquids, dust and other substances from entering the accommodating cavity, thereby effectively protecting the battery pack 20. At the same time, the seal 40 cooperates with the connection column 23 to jointly define the connection hole 211, thereby ensuring that the first fastener 31 can pass through the box body 21 and connect to the longitudinal beam 10. For example, Figure 3 and Figure 5 As shown, the battery pack 20 is arranged on the lower side of the longitudinal beam 10 , and the sealing member 40 is provided at the upper end of the connecting hole 211 .

[0044] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 5 The sealing member 40 is a sealing bolt, which defines a threaded hole through which the sealing member 40 is threadedly connected to the first fastener 31. Thus, the threaded connection is simple and easy to operate, thereby improving the connection efficiency between the sealing member 40 and the first fastener 31. Furthermore, the sealing bolt has a simple structure and low cost, thus facilitating mass production.

[0045] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 The chassis structure 100 includes: a first bracket 51, one end of the first bracket 51 (such as Figure 1 The upper end of the first bracket 51 shown in FIG. 1 is connected to the longitudinal beam 10, and the other end of the first bracket 51 (as shown in FIG. Figure 1 The lower end of the first bracket 51 shown in FIG. 5 extends toward the box body 21 , and the battery pack 20 is fastened to the first bracket 51 via a first fastener 31 .

[0046] In this way, the first bracket 51 is provided, and the first fastener 31 can be connected to the longitudinal beam 10 through the first bracket 51, so that the battery pack 20 and the longitudinal beam 10 can be fixed. At the same time, the processing difficulty of the longitudinal beam 10 can be reduced and the processing of the longitudinal beam 10 can be facilitated.

[0047] For example, Figure 1 and Figure 3 As shown, the first bracket 51 extends in the up-down direction, the upper end of the first bracket 51 is connected to the longitudinal beam 10 , the lower end of the first bracket 51 extends toward the box body 21 , and the first fastener 31 passes through the connecting hole 211 and is screwed to the first bracket 51 .

[0048] According to some embodiments of the present invention, referring to Figure 3 and Figure 5 The battery pack 20 is provided with a hanging plate 24, which is provided on both sides of the box body 21 in the front and rear directions (such as Figure 5The chassis structure 100 extends along the left-right direction of the vehicle and extends along the front and rear sides of the box body 21 shown in the figure. The chassis structure 100 may also include: a second fastener 32, which is passed through the lifting plate 24 to fasten the battery pack 20 to the longitudinal beam 10.

[0049] Thus, the provision of the hanging plate 24 facilitates the second fasteners 32 passing through the hanging plate 24 to secure the battery pack 20 to the longitudinal beam 10, thereby facilitating the securement of the box 21 to the longitudinal beam 10. Furthermore, the second fasteners 32 cooperate with the first fasteners 31 to provide multiple connection locations between the battery pack 20 and the longitudinal beam 10, thereby strengthening the securing strength between the battery pack 20 and the box 21 and effectively preventing separation of the battery pack 20 from the box 21. Furthermore, the reasonable placement of the hanging plate 24 prevents any conflict between the hanging plate 24 and the first fasteners 31, thereby ensuring the rationality of the design of the box 21.

[0050] For example, Figure 3 and Figure 5 As shown, the front and rear sides of the box body 21 are provided with a hanging plate 24, and the hanging plate 24 extends in the left and right directions. The second fastener 32 on the front side passes through the front hanging plate 24 from bottom to top and is connected to the longitudinal beam 10, and two second fasteners 32 are provided on the front side, and the two second fasteners 32 are respectively connected to the two longitudinal beams 10 on the left and right sides. The second fastener 32 on the rear side passes through the rear hanging plate 24 from bottom to top and is connected to the longitudinal beam 10, and two second fasteners 32 are provided on the rear side, and the two second fasteners 32 are respectively connected to the two longitudinal beams 10 on the left and right sides.

[0051] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 3 The chassis structure 100 includes: a second bracket 52, one end of the second bracket 52 (such as Figure 1 The upper end of the second bracket 52 shown in FIG. 1 is connected to the longitudinal beam 10, and the other end of the second bracket 52 (as shown in FIG. Figure 1 The lower end of the second bracket 52 shown in FIG. 5 extends toward the box body 21 , and the battery pack 20 is fastened to the second bracket 52 via a second fastener 32 .

[0052] Thus, by providing the second bracket 52, the second fastener 32 can be connected to the longitudinal beam 10 through the second bracket 52, thereby securing the battery pack 20 to the longitudinal beam 10. This also reduces the difficulty of machining the longitudinal beam 10 and facilitates its processing. Furthermore, the first bracket 51 and the second bracket 52 are positioned appropriately, ensuring that the box 21 can be properly secured to the longitudinal beam 10.

[0053] For example, Figure 1 and Figure 3As shown, the upper end of the second bracket 52 is connected to the longitudinal beam 10, and the lower end of the second bracket 52 extends toward the box body 21. Two second brackets 52 are provided on the left longitudinal beam 10, and the first bracket 51 of the left longitudinal beam 10 is located between the two second brackets 52. Two second brackets 52 are provided on the right longitudinal beam 10, and the first bracket 51 of the right longitudinal beam 10 is located between the two second brackets 52.

[0054] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 The chassis structure 100 includes a buffer member 60 disposed between the box body 21 and the two longitudinal beams 10. As a result, when the vehicle is in operation, the shaking force of the vehicle is transmitted to the battery pack 20 through the longitudinal beams 10. The buffer member 60 can buffer the shaking force transmitted from the longitudinal beams 10 to the battery pack 20, thereby protecting the battery pack 20. At the same time, the buffer member 60 can also insulate the battery pack 20, improving the thermal management level of the battery pack 20 and preventing thermal runaway of the battery pack 20 from damaging other components.

[0055] According to some embodiments of the present invention, referring to Figure 1 、 Figure 2 and Figure 3 The battery pack 20 is located at both ends of the vehicle in the left and right directions (such as Figure 1 The left and right ends of the battery pack 20 shown extend beyond the two longitudinal beams 10. This allows full utilization of the space on both sides of the longitudinal beams 10, effectively improving space utilization and accommodating the battery pack 20. This increases the battery pack's storage capacity and ensures the vehicle's endurance.
