[0002] In related technologies, components such as the longitudinal beams, cross beams, and reinforcing plates of the vehicle frame are connected together by riveting. To ensure that the cross beams are flat, the riveting location is usually adjusted to the web surface of the longitudinal beam for riveting. When riveting, the riveting is usually completed with riveting pliers through the connecting holes of the longitudinal and cross beams.

[0003] However, the existing chassis also has significant drawbacks: the chassis is difficult to meet the requirements for arranging a centrally located large-capacity battery pack. In addition, after the longitudinal beams and cross plates are riveted, the rivets protrude from the longitudinal beams and cross plates, which cannot meet the installation of the cargo box and the needs of customers.

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-3 The vehicle frame 1 according to an embodiment of the present utility model is described.

[0022] like Figures 1-3 As shown, the vehicle frame 1 according to an embodiment of the present invention includes two first longitudinal beams 30. The first longitudinal beams 30 can bear and support loads, and can absorb and disperse collision forces during a vehicle collision to protect the safety of the occupants.

[0023] like Figure 1 and Figure 3 As shown, two first longitudinal beams 30 are spaced apart in a first direction. Each first longitudinal beam 30 includes a first plate 300, a second plate 301, and a third plate 302. In a second direction, the second plate 301 and the third plate 302 are respectively connected to the two ends of the first plate 300. Moreover, along the second direction, the second plate 301 is located above the third plate 302. That is, the second plate 301 is connected to the upper end of the first plate 300, and the third plate 302 is connected to the lower end of the first plate 300.

[0024] In the first direction, a first crossbeam 60 connects the two first longitudinal beams 30. The first plate 300, the second plate 301, and the third plate 302 are components of the first longitudinal beam 30, all of which can play a load-bearing and supporting role. In the second direction, the second plate 301 and the third plate 302 are respectively connected to the two ends of the first plate 300, and the second plate 301 is located above the third plate 302 along the second direction. That is to say, in the second direction, the second plate 301 is connected to one end of the first plate 300, and the third plate 302 is connected to the other end of the first plate 300. The second direction is the vertical direction. The second plate 301 is connected to the upper end of the first plate 300, and the third plate 302 is connected to the lower end of the first plate 300. The second plate 301, the third plate 302, and the first plate 300 are connected to form the first longitudinal beam 30.

[0025] like Figure 3 As shown, in the first direction, the second plate 301 extends toward the two first longitudinal beams 30 adjacent to each other, and the third plate 302 extends toward the two first longitudinal beams 30 away from each other. The first direction and the second direction are perpendicular to each other. That is, in the first direction, the second plate 301 extends toward the first crossbeam 60, and the third plate 302 extends away from the first crossbeam 60. This increases the installation space for the battery pack, allowing for the installation of large-capacity, wide battery packs. The first direction and the second direction are perpendicular to each other.

[0026] Thus, the first longitudinal beams 30 are spaced apart in the first direction, the second plate 301 extends toward the two first longitudinal beams 30 in a direction close to each other, and the third plate 302 extends toward the two first longitudinal beams 30 in a direction away from each other. This increases the installation space of the battery pack so as to facilitate the installation of a large-capacity battery pack.

[0027] Among them, such as Figures 1-3 As shown, the frame also includes a second longitudinal beam 20 and a third longitudinal beam 10. In the third direction, the second longitudinal beam 20 is connected to one end of the first longitudinal beam 30. There are two second longitudinal beams 20, which are spaced apart in the first direction. In the third direction, the third longitudinal beam 10 is connected to the end of the first longitudinal beam 30 away from the second longitudinal beam 20. There are two third longitudinal beams 10, which are spaced apart in the first direction.

[0028] The third longitudinal beam 10, the second longitudinal beam 20, and the first longitudinal beam 30 are connected in the third direction. There are two of each of the three longitudinal beams 10, 20, and 30. The two third longitudinal beams 10 are spaced apart in the first direction, and a second crossbeam 70 connects the two third longitudinal beams 10. The two second longitudinal beams 20 are spaced apart in the first direction, and a third crossbeam 80 connects the two second longitudinal beams 20. The two first longitudinal beams 30 are spaced apart in the first direction, and a first crossbeam 60 connects the two first longitudinal beams 30. Thus, the third longitudinal beams 10, 20, 30, 60, 70, and 80 can be constructed as the overall structure of the frame 1, which can play a role in load-bearing and support, and at the same time can absorb and disperse the collision force in the event of a vehicle collision, protecting the safety of the occupants.

[0029] In the third direction, the third longitudinal beam 10 is connected to the end of the first longitudinal beam 30 away from the second longitudinal beam 20. That is, the third longitudinal beam 10 is located on one side of the second longitudinal beam 20, and the third longitudinal beam 10 and the second longitudinal beam 20 are respectively connected to the two ends of the first longitudinal beam 30. For example, in the third direction, the third longitudinal beam 10 and the second longitudinal beam 20 are arranged front to back, and the third longitudinal beam 10 is located in front of the second longitudinal beam 20. The third longitudinal beam 10 and the second longitudinal beam 20 are respectively connected to the two ends of the first longitudinal beam 30. That is, the third longitudinal beam 10 and the second longitudinal beam 20 are respectively connected to the first longitudinal beam 30 to form the frame 1. The third longitudinal beam 10 and the first longitudinal beam 30 adopt a stepped structure and do not require riveting. The second longitudinal beam 20 and the first longitudinal beam 30 adopt a special structure to ensure that the cross plate remains straight and without protrusions after the second longitudinal beam 20 and the first longitudinal beam 30 are spliced, thereby meeting the installation of the cargo box and the needs of customers.

[0030] Specifically, such as Figure 1 and Figure 3As shown, the third longitudinal beam 10 includes a fourth plate 100, a fifth plate 101, and a sixth plate 102. In the second direction, the fifth plate 101 is connected to one end of the fourth plate 100, and the sixth plate 102 is connected to the other end of the fourth plate 100. In the first direction, both the fifth plate 101 and the sixth plate 102 extend toward the two third longitudinal beams 10 that are adjacent to each other. The second longitudinal beam 20 includes a seventh plate 200, an eighth plate 201, and a ninth plate 202. In the second direction, the eighth plate 201 is connected to one end of the seventh plate 200, and the ninth plate 202 is connected to the other end of the seventh plate 200. In the first direction, both the eighth plate 201 and the ninth plate 202 extend toward the two second longitudinal beams 20 that are adjacent to each other. The first, second, and third directions are arranged perpendicularly to each other.

[0031] It should be noted that the fourth plate 100, the fifth plate 101, and the sixth plate 102 are all components of the third longitudinal beam 10 and can all play a load-bearing and supporting role. In the second direction, the fifth plate 101 is connected to one end of the fourth plate 100, and the sixth plate 102 is connected to the other end of the fourth plate 100. The two ends of the fourth plate 100 in the second direction are respectively connected to the fifth plate 101 and the sixth plate 102. The fifth plate 101, the sixth plate 102, and the fourth plate 100 are connected to form the third longitudinal beam 10. In the first direction, the fifth plate 101 and the sixth plate 102 both extend towards the two third longitudinal beams 10 that are close to each other. That is to say, in the first direction, the extension direction of the fifth plate 101 and the sixth plate 102 is the same, extending towards the second crossbeam 70, so as to avoid occupying the outer space.

[0032] The seventh plate 200, the eighth plate 201, and the ninth plate 202 are all components of the second longitudinal beam 20, and all serve a load-bearing and supporting function. In the second direction, the eighth plate 201 is connected to one end of the seventh plate 200, and the ninth plate 202 is connected to the other end of the seventh plate 200. The two ends of the seventh plate 200 in the second direction are connected to the eighth plate 201 and the ninth plate 202, respectively. In the first direction, both the eighth plate 201 and the ninth plate 202 extend towards the two second longitudinal beams 20 adjacent to each other. That is to say, in the first direction, the extension direction of the eighth plate 201 and the ninth plate 202 is the same, extending towards the third crossbeam 80, to avoid occupying the outer space. Among them, the first, second, and third directions are arranged perpendicularly to each other.

[0033] In addition, such as Figure 2 and Figure 3As shown, the frame 1 also includes a first rivet 40 and a second rivet 50. The first rivet 40 is used to fix the first plate 300 and the seventh plate 200, and the second rivet 50 is used to fix the second plate 301 and the eighth plate 201. Both the first rivet 40 and the second rivet 50 can be used to connect two parts or components with through holes. The first rivet 40 is used to fix the first plate 300 and the seventh plate 200, and the first rivet 40 can achieve a fixed connection between the first plate 300 and the seventh plate 200. The second rivet 50 is used to fix the second plate 301 and the eighth plate 201, and the second rivet 50 can achieve a fixed connection between the second plate 301 and the eighth plate 201, thereby achieving the connection between the second longitudinal beam 20 and the first longitudinal beam 30.

[0034] Of course, such as Figure 3 As shown, both the second plate 301 and the eighth plate 201 are provided with a downwardly recessed assembly groove 303, and the second rivet 50 is fixed at the assembly groove 303. The assembly groove 303 mainly facilitates assembly. The fact that both the second plate 301 and the eighth plate 201 are provided with a downwardly recessed assembly groove 303, and the second rivet 50 is fixed at the assembly groove 303, ensures that the second plate 301 and the eighth plate 201 are straight after the second longitudinal beam 20 and the first longitudinal beam 30 are connected. It also prevents the second rivet 50 from protruding from the second plate 301 and the eighth plate 201 after riveting, thus meeting the user's needs.

[0035] Furthermore, such as Figure 3 As shown, the second rivet 50 includes: a first rivet post 500, a first rivet head 501, and a second rivet head 502. The first rivet post 500 passes through the second plate 301 and the eighth plate 201. The first rivet head 501 is connected to the end of the first rivet post 500 away from the ninth plate 202. The second rivet head 502 is connected to the end of the first rivet post 500 adjacent to the ninth plate 202. The second plate 301 and the eighth plate 201 are fixed between the first rivet head 501 and the second rivet head 502.

[0036] The first rivet post 500, the first rivet head 501, and the second rivet head 502 are all components of the second rivet 50. The first rivet post 500 can connect two parts or components with through holes. The first rivet head 501 and the second rivet head 502 mainly connect and fix the components. The first rivet post 500 passes through the second plate 301 and the eighth plate 201, thus enabling the second rivet 50 to fix the second plate 301 and the eighth plate 201. The first rivet head 501 is connected to the first rivet post 500 at a point away from the ninth plate 202. At one end, the second rivet head 502 is connected to one end of the first rivet post 500 adjacent to the ninth plate 202. The first rivet head 501 and the second rivet head 502 are respectively connected to the two ends of the first rivet post 500 in the second direction. The second plate 301 and the eighth plate 201 are fixed between the first rivet head 501 and the second rivet head 502. The second plate 301 and the eighth plate 201 are fixed between the first rivet head 501 and the second rivet head 502. At this time, the fixed connection between the second plate 301 and the eighth plate 201 in the second direction can be realized.

[0037] In addition, such as Figure 3 As shown, the first rivet head 501 is constructed as a flat-head rivet head, and the second rivet head 502 is constructed as a round-head rivet head. The flat-head rivet head structure reduces pressure on the mating surfaces, avoiding unnecessary damage. Constructing the first rivet head 501 as a flat-head rivet head better suits actual working conditions, preventing the second rivet 50 from protruding from the second plate 301 and the eighth plate 201 after riveting, thus meeting user needs. The round-head rivet head structure improves the stability of the connection and the efficiency of maintenance and inspection. Constructing the second rivet head 502 as a round-head rivet head better suits actual working conditions, allowing the second plate 301 and the eighth plate 201 to be fixed between the first rivet head 501 and the second rivet head 502.

[0038] It should be noted that, as Figure 3 As shown, the first rivet 40 includes: a second rivet post 400, a third rivet head 401, and a fourth rivet head 402. The second rivet post 400 passes through the first plate 300 and the seventh plate 200. The third rivet head 401 is connected to one end of the second rivet post 400, and the fourth rivet head 402 is connected to the other end of the second rivet post 400. The first plate 300 and the seventh plate 200 are fixed between the third rivet head 401 and the fourth rivet head 402.

[0039] The second rivet post 400, the third rivet head 401, and the fourth rivet head 402 are all components of the first rivet 40. The second rivet post 400 can connect two parts or components with through holes. The third rivet head 401 and the fourth rivet head 402 mainly connect and fix the components. The second rivet post 400 passes through the first plate 300 and the seventh plate 200, thus allowing the first rivet 40 to fix the first plate 300 and the seventh plate 200. The third rivet head 401 is connected to one end of the second rivet post 400, and the fourth rivet head 402 is connected to the other end of the second rivet post 400. In other words, the third rivet head 401... The rivet head 401 is connected to the end of the second rivet post 400 away from the first crossbeam 60, and the fourth rivet head 402 is connected to the end of the second rivet post 400 adjacent to the first crossbeam 60. The third rivet head 401 and the fourth rivet head 402 are respectively connected to the two ends of the second rivet post 400 in the first direction. The first plate 300 and the seventh plate 200 are fixed between the third rivet head 401 and the fourth rivet head 402. The first plate 300 and the seventh plate 200 are fixed between the third rivet head 401 and the fourth rivet head 402. At this time, the first plate 300 and the seventh plate 200 can be fixedly connected in the first direction.

[0040] In addition, such as Figure 3 As shown, the third rivet head 401 and the fourth rivet head 402 are both constructed with round heads. The round head structure improves the stability of the connection and the efficiency of maintenance and inspection. Constructing the third rivet head 401 and the fourth rivet head 402 with round heads better suits actual working conditions, allowing the first plate 300 and the seventh plate 200 to be fixed between the third rivet head 401 and the fourth rivet head 402.

[0041] It should be noted that, as Figure 1 As shown, in the third direction, the second section 301 and the fifth section 101 are spaced apart to form a stepped structure. In the third direction, the stepped structure between the second section 301 and the fifth section 101 eliminates the need for riveting, ensuring that the crossbeam remains straight and without protrusions after the third longitudinal beam 10 and the first longitudinal beam 30 are joined, thus meeting the installation requirements of the cargo box and the needs of customers.

[0042] Optionally, in the first direction, the end of the second longitudinal beam 20 adjacent to the first longitudinal beam 30 is inserted into the inner side of the first longitudinal beam 30, and the end of the third longitudinal beam 10 adjacent to the first longitudinal beam 30 is inserted into the inner side of the first longitudinal beam 30. That is, in the first direction, the end of the first plate 300 adjacent to the seventh plate 200 and the end of the seventh plate 200 adjacent to the first plate 300 are opposite to each other, and the seventh plate 200 can be disposed inside the first plate 300. In the first direction, the end of the first plate 300 adjacent to the fourth plate 100 and the end of the fourth plate 100 adjacent to the first plate 300 are opposite to each other, and the fourth plate 100 can be disposed inside the first plate 300. The first plate 300 and the seventh plate 200 are in a fixed connection state, and the first plate 300 and the fourth plate 100 are spaced apart, so that the second plate 301 and the fifth plate 101 can form a stepped structure.

[0043] The vehicle according to an embodiment of the present invention includes a battery pack and the aforementioned frame 1. The battery pack is disposed on the second plate 301 and the third plate 302. Disposing the battery pack on the second plate 301 and the third plate 302 can reduce the possibility of torsional deformation and collision, thereby improving the safety of the battery pack. Furthermore, the second plate 301 and the third plate 302 are Z-shaped, so that in the first direction, i.e., the first longitudinal beam 30, can be configured to house battery packs in both the left and right directions. In this case, the frame 1 can meet the requirement of arranging a centrally located, large-capacity battery pack.
