[0044] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Figures 1-10 The vehicle frame 100 according to the first - aspect embodiment of the present utility model will be described below. In the following description of the present application, the vehicle frame 100 is taken as an example for a vehicle 200.

[0045] As Figure 1 and Figure 3 shown, the vehicle frame 100 according to the first - aspect embodiment of the present utility model includes a first longitudinal beam 1 and a second longitudinal beam 2.

[0046] Specifically, the first longitudinal beam 1 has a first mounting portion 11. The second longitudinal beam 2 extends along the length direction of the first longitudinal beam 1. The first longitudinal beam 1 and the second longitudinal beam 2 are spaced apart in a direction perpendicular to the length direction of the first longitudinal beam 1. The second longitudinal beam 2 has a second mounting portion 21. The second mounting portion 21 is opposite to the first mounting portion 11. The minimum distance between the second mounting portion 21 and the first mounting portion 11 is greater than or less than the minimum distance between the position of the first longitudinal beam 1 except at the first mounting portion 11 and the position of the second longitudinal beam 2 except at the second mounting portion 21.

[0047] For example, in the examples of Figure 1 and Figure 3 , the first mounting portion 11 is located at the middle position of the first longitudinal beam 1, and the second mounting portion 21 is located at the middle position of the second longitudinal beam 2. Both the first longitudinal beam 1 and the second longitudinal beam 2 extend in the front-rear direction, and the first longitudinal beam 1 and the second longitudinal beam 2 are arranged at intervals in the left-right direction. The minimum distance between the second mounting portion 21 and the first mounting portion 11 (i.e., the distance in the left-right direction) is greater than the minimum distance between the position of the first longitudinal beam 1 except at the first mounting portion 11 and the position of the second longitudinal beam 2 except at the second mounting portion 21 (as shown in Figure 1 ). Thus, the space between the first mounting portion 11 and the second mounting portion 21 is increased, that is, the space on the side where the first mounting portion 11 and the second mounting portion 21 are away from each other can be communicated with the space between the first mounting portion 11 and the second mounting portion 21, so as to be used for installing and placing a larger number of battery packs 201, effectively utilizing the space between the first mounting portion 11 and the second mounting portion 21 and improving the space utilization rate on the frame 100. Or the minimum distance between the second mounting portion 21 and the first mounting portion 11 is less than the minimum distance between the position of the first longitudinal beam 1 except at the first mounting portion 11 and the position of the second longitudinal beam 2 except at the second mounting portion 21 (as shown in Figure 3 ). Thus, the distance between the first mounting portion 11 and the second mounting portion 21 is relatively close, effectively utilizing the space between the first mounting portion 11 and the second mounting portion 21, so that the available space on the side where the first mounting portion 11 and the second mounting portion 21 are away from each other is increased, and a larger number of battery packs 201 can be installed.

[0048] With such a setting, the structures of the first longitudinal beam 1 and the second longitudinal beam 2 are simple and easy to produce, reducing the production difficulty of the first longitudinal beam 1 and the second longitudinal beam 2 and improving the production efficiency of the first longitudinal beam 1 and the second longitudinal beam 2. In addition, when the frame 100 is used for the vehicle 200 and the battery pack 201 of the vehicle 200 is installed on the frame 100, compared with the traditional technology where the length direction of the battery pack is the same as the length direction of the first longitudinal beam and the second longitudinal beam when the battery packs are arranged, for example, three battery packs are respectively installed on the sides where the first longitudinal beam and the second longitudinal beam are away from each other (the three battery packs can be stacked in the up-down direction), in this application, through the setting of the first mounting portion 11 and the second mounting portion 21, when the battery packs 201 are arranged, the length direction of the battery packs 201 can be perpendicular to the length direction of the first longitudinal beam 1 and the second longitudinal beam 2 (as shown in Figure 11 and Figure 12 ), effectively utilizing the interval between the first longitudinal beam 1 and the second longitudinal beam 2, that is, improving the space utilization rate in the frame 100 and increasing the installation quantity of the battery packs 201 (for example, six battery packs 201 can be respectively installed on the first longitudinal beam 1 and the second longitudinal beam 2, a total of twelve battery packs 201, as shown in Figure 11 and Figure 12As shown, the endurance of vehicle 200 is improved, the usage efficiency of vehicle 200 is increased, and the market demand for large-capacity power battery packs 201 is also met. It should be noted that the arrangement of multiple battery packs 201 is not limited to this. For example, three battery packs 201 are installed on the first longitudinal beam 1 and six battery packs 201 are installed on the second longitudinal beam 2, or six battery packs 201 are installed on the first longitudinal beam 1 and three battery packs 201 are installed on the second longitudinal beam 2.

[0049] According to the vehicle frame 100 of the present utility model, the structures of the first longitudinal beam 1 and the second longitudinal beam 2 are simple and easy to manufacture. In addition, when the battery pack 201 of the vehicle 200 is installed on the vehicle frame 100, compared with the traditional technology, through the first mounting portion 11 and the second mounting portion 21, the space between the first longitudinal beam 1 and the second longitudinal beam 2 is effectively utilized during the installation of the battery pack 201, that is, the space utilization rate in the vehicle frame 100 is improved, and the number of installed battery packs 201 is increased, thereby improving the endurance of the vehicle 200 and also meeting the market demand for large-capacity power battery packs 201.

[0050] According to some embodiments of the present utility model, referring to Figure 1 and Figure 2 , the first mounting portion 11 is formed by a part of the first longitudinal beam 1 protruding away from the second longitudinal beam 2; and / or, the second mounting portion 21 is formed by a part of the second longitudinal beam 2 protruding away from the first longitudinal beam 1. For example, the settings of the first mounting portion 11 and the second mounting portion 21 include the following situations: First, only the first mounting portion 11 is formed by a part (i.e., the middle part) of the first longitudinal beam 1 protruding away from the second longitudinal beam 2, and the second mounting portion 21 extends along the length direction of the first longitudinal beam 1 from a part of the second longitudinal beam 2. Second, only the second mounting portion 21 is formed by a part (i.e., the middle part) of the second longitudinal beam 2 protruding away from the first longitudinal beam 1, and the first mounting portion 11 extends along the length direction of the first longitudinal beam 1 from a part of the first longitudinal beam 1. Third, the first mounting portion 11 is formed by a part of the first longitudinal beam 1 protruding away from the second longitudinal beam 2. At the same time, the second mounting portion 21 is formed by a part of the second longitudinal beam 2 protruding away from the first longitudinal beam 1 (as shown in Figure 1 ).

[0051] With such a setting, the first mounting portion 11 and the second mounting portion 21 extend outward from the frame 100, increasing the distance between the first mounting portion 11 and the second mounting portion 21. Effectively ensuring that the minimum distance between the second mounting portion 21 and the first mounting portion 11 is greater than the minimum distance between the position of the first longitudinal beam 1 other than the first mounting portion 11 and the position of the second longitudinal beam 2 other than the second mounting portion 21, reasonably utilizing the space between the first mounting portion 11 and the second mounting portion 21, the space on the side where the first mounting portion 11 and the second mounting portion 21 are away from each other can be communicated with the space between the first mounting portion 11 and the second mounting portion 21, increasing the space for installing the battery pack 201 on the frame 100, that is, the number of battery packs 201 that can be installed can be increased, improving the endurance of the vehicle 200, reducing the installation difficulty of the battery pack 201, improving the installation efficiency of the frame 100 and the battery pack 201, and thus improving the installation efficiency of the vehicle 200.

[0052] According to some embodiments of the present invention, referring to Figure 1 , the first mounting portion 11 includes a first mounting section 111 and two second mounting sections 112. The two second mounting sections 112 are opposite to each other along the length direction of the first longitudinal beam 1. One ends of the two second mounting sections 112 are respectively connected to the first longitudinal beam 1, and the other ends of the two second mounting sections 112 extend in a direction away from the second longitudinal beam 2. The two ends of the first mounting section 111 are respectively connected to the above-mentioned other ends of the two second mounting sections 112.

[0053] For example, in the example of Figure 1 , the two second mounting sections 112 are opposite to each other in the front-rear direction. The right ends of the two second mounting sections 112 are respectively connected to the first longitudinal beam 1. The left ends of the two second mounting sections 112 extend in a direction away from the second longitudinal beam 2. The left ends of the two second mounting sections 112 are respectively connected to the front and rear ends of the first mounting section 111. The shape of the first mounting portion 11 is generally in a "C" shape. With such a setting, the structure of the first mounting portion 11 is simple and easy to process, reducing the production difficulty of the first mounting portion 11 and improving the production efficiency of the first mounting portion 11, thus improving the production efficiency of the first longitudinal beam 1. In addition, the shape of the space between the first mounting portion 11 and the second longitudinal beam 2 is adapted to the shape of the battery pack 201, which helps to improve the installation stability of the battery pack 201, and thus improves the use stability of the vehicle 200.

[0054] According to other embodiments of the present invention, referring to Figure 1, the second mounting portion 21 includes a third mounting section 211 and two fourth mounting sections 212. The two fourth mounting sections 212 are opposite to each other along the length direction of the second longitudinal beam 2. One end of each of the two fourth mounting sections 212 is connected to the second longitudinal beam 2 respectively, and the other end of each of the two fourth mounting sections 212 extends in a direction away from the first longitudinal beam 1. Both ends of the third mounting section 211 are connected to the above-mentioned other ends of the fourth mounting sections 212 respectively.

[0055] For example, in Figure 1 example, the two fourth mounting sections 212 are opposite to each other in the front-rear direction. The right ends of the two fourth mounting sections 212 are connected to the second longitudinal beam 2 respectively. The right ends of the two second mounting sections 112 extend in a direction away from the first longitudinal beam 1. The right ends of the two fourth mounting sections 212 are connected to the front and rear ends of the third mounting section 211 respectively. The shape of the second mounting portion 21 is generally "C"-shaped. With such a setting, the second mounting portion 21 has a simple structure and is easy to process, reducing the production difficulty of the second mounting portion 21 and improving the production efficiency of the second mounting portion 21, thereby improving the production efficiency of the second longitudinal beam 2. In addition, the shape of the space between the third mounting section 211 and the fourth mounting section 212 is adapted to the shape of the battery pack 201, which helps to improve the mounting stability of the battery pack 201, thereby improving the use stability of the vehicle 200.

[0056] According to some other embodiments of the present invention, referring to Figure 1 , the first mounting portion 11 includes a first mounting section 111 and two second mounting sections 112. The two second mounting sections 112 are opposite to each other along the length direction of the first longitudinal beam 1. One end of each of the two second mounting sections 112 is connected to the first longitudinal beam 1 respectively, and the other end of each of the two second mounting sections 112 extends in a direction away from the second longitudinal beam 2. Both ends of the first mounting section 111 are connected to the above-mentioned other ends of the two second mounting sections 112 respectively. At the same time, the second mounting portion 21 includes a third mounting section 211 and two fourth mounting sections 212. The two fourth mounting sections 212 are opposite to each other along the length direction of the second longitudinal beam 2. One end of each of the two fourth mounting sections 212 is connected to the second longitudinal beam 2 respectively, and the other end of each of the two fourth mounting sections 212 extends in a direction away from the first longitudinal beam 1. Both ends of the third mounting section 211 are connected to the above-mentioned other ends of the fourth mounting sections 212 respectively.

[0057] With such a setting, the first mounting portion 11 and the second mounting portion 21 have a simple structure and are easy to process, reducing the production difficulty of the first mounting portion 11 and the second mounting portion 21, improving the production efficiency of the first mounting portion 11 and the second mounting portion 21, thereby improving the production efficiency of the first longitudinal beam 1 and the second longitudinal beam 2, and improving the production efficiency of the vehicle frame 100. In addition, the spatial shape between the first mounting portion 11 and the second longitudinal beam 2 is adapted to the shape of the battery pack 201, and the spatial shape between the third mounting section 211 and the fourth mounting section 212 is adapted to the shape of the battery pack 201, which helps to improve the mounting stability of the battery pack 201, thereby improving the use stability of the vehicle 200.

[0058] According to some embodiments of the present invention, referring to Figure 1 , the first mounting section 111 extends along the length direction of the first longitudinal beam 1; and / or, the third mounting section 211 extends along the length direction of the second longitudinal beam 2. For example, the settings of the first mounting section 111 and the third mounting section 211 include the following situations: First, the first mounting section 111 extends along the length direction of the first longitudinal beam 1. Second, the third mounting section 211 extends along the length direction of the second longitudinal beam 2. Third, the first mounting section 111 extends along the length direction of the first longitudinal beam 1. At the same time, the third mounting section 211 extends along the length direction of the second longitudinal beam 2 (as Figure 1 shown).

[0059] With such a setting, the first mounting section 111 is parallel to the side of the battery pack 201, avoiding a gap between the first mounting section 111 and the battery pack 201, and also improving the degree of fit between the first mounting section 111 and the side of the battery pack 201, thereby improving the mounting stability of the battery pack 201 on the first longitudinal beam 1, and further improving the use safety of the vehicle 200. In addition, the third mounting section 211 is parallel to the side of the battery pack 201, avoiding a gap between the third mounting section 211 and the battery pack 201, and also improving the degree of fit between the third mounting section 211 and the side of the battery pack 201, thereby improving the mounting stability of the battery pack 201 on the second longitudinal beam 2, and further improving the use safety of the vehicle 200.

[0060] According to some embodiments of the present invention, referring to Figure 1, the other ends of the two second mounting segments 112 extend obliquely towards the direction of approaching each other; and / or, the other ends of the two fourth mounting segments 212 extend obliquely towards the direction of approaching each other. For example, the arrangements of the second mounting segment 112 and the fourth mounting segment 212 include the following situations: First, the other ends of the two second mounting segments 112 extend obliquely towards the direction of approaching each other. Second, the other ends of the two fourth mounting segments 212 extend obliquely towards the direction of approaching each other. Third, the other ends of the two second mounting segments 112 extend obliquely towards the direction of approaching each other. At the same time, the other ends of the two fourth mounting segments 212 extend obliquely towards the direction of approaching each other (as Figure 1 shown).

[0061] The left ends of the two second mounting segments 112 extend obliquely towards the direction of approaching each other. The right ends of the two fourth mounting segments 212 extend obliquely towards the direction of approaching each other. With such an arrangement, the two second mounting segments 112 are obliquely arranged, which improves the structural strength of the second mounting segment 112, improves the connection strength between the first mounting segment 111 and the first longitudinal beam 1 through the second mounting segment 112, thereby improving the structural strength of the first mounting portion 11, further extending the service life of the first longitudinal beam 1, and also improving the installation stability of the battery pack 201 on the first longitudinal beam 1. In addition, the two fourth mounting segments 212 are obliquely arranged, which improves the structural strength of the fourth mounting segment 212, improves the connection strength between the third mounting segment 211 and the second longitudinal beam 2 through the fourth mounting segment 212, thereby improving the structural strength of the second mounting portion 21, further extending the service life of the second longitudinal beam 2, and also improving the installation stability of the battery pack 201 on the second longitudinal beam 2, improving the use performance of the vehicle frame 100.

[0062] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the first mounting portion 11 is formed by a part of the first longitudinal beam 1 being recessed towards the side where the second longitudinal beam 2 is located; and / or, the second mounting portion 21 is formed by a part of the second longitudinal beam 2 being recessed towards the side where the first longitudinal beam 1 is located.

[0063] For example, the arrangements of the first mounting portion 11 and the second mounting portion 21 include the following situations: First, only the first mounting portion 11 is formed by a part of the first longitudinal beam 1 being recessed towards the side where the second longitudinal beam 2 is located, and the second mounting portion 21 extends along the length direction of the second longitudinal beam 2 by a part of the second longitudinal beam 2. Second, only the second mounting portion 21 is formed by a part of the second longitudinal beam 2 being recessed towards the side where the first longitudinal beam 1 is located, and the first mounting portion 11 extends along the length direction of the first longitudinal beam 1 by a part of the first longitudinal beam 1. Third, the first mounting portion 11 is formed by a part of the first longitudinal beam 1 being recessed towards the side where the second longitudinal beam 2 is located. At the same time, the second mounting portion 21 is formed by a part of the second longitudinal beam 2 being recessed towards the side where the first longitudinal beam 1 is located.

[0064] With such a setting, the first mounting portion 11 and the second mounting portion 21 contract towards the inside of the vehicle frame 100, reducing the distance between the first mounting portion 11 and the second mounting portion 21. Effectively, it is ensured that the minimum distance between the second mounting portion 21 and the first mounting portion 11 is less than the minimum distance between the position of the first longitudinal beam 1 except at the first mounting portion 11 and the position of the second longitudinal beam 2 except at the second mounting portion 21. The space between the first longitudinal beam 1 and the second longitudinal beam 2 is reasonably utilized, increasing the space for installing the battery pack 201 on the vehicle frame 100. That is, it is beneficial to increase the number of battery packs 201 installed, improve the endurance of the vehicle 200, reduce the installation difficulty of the battery pack 201, improve the installation efficiency of the vehicle frame 100 and the battery pack 201, and thus improve the installation efficiency of the vehicle 200.

[0065] Among them, the first mounting portion 11 includes a first mounting section 111 and two second mounting sections 112. The two second mounting sections 112 are opposite to each other along the length direction of the first longitudinal beam 1. The left ends of the two second mounting sections 112 are respectively connected to the first longitudinal beam 1. The right ends of the two second mounting sections 112 extend towards the direction close to the second longitudinal beam 2. The front and rear ends of the first mounting section 111 are respectively connected to the right ends of the two second mounting sections 112. The second mounting portion 21 includes a third mounting section 211 and two fourth mounting sections 212. The two fourth mounting sections 212 are opposite to each other along the length direction of the second longitudinal beam 2. The left ends of the two fourth mounting sections 212 are respectively connected to the second longitudinal beam 2. The left ends of the two fourth mounting sections 212 extend towards the direction close to the first longitudinal beam 1. The front and rear ends of the third mounting section 211 are respectively connected to the left ends of the two fourth mounting sections 212. Thus, the structures of the first mounting portion 11 and the second mounting portion 21 are simple, thereby improving the production efficiency of the first longitudinal beam 1 and the second longitudinal beam 2. In addition, the first mounting portion 11 and the second mounting portion 21 are open to the outside of the vehicle 200, facilitating the installation of multiple battery packs 201, reducing the installation difficulty of multiple battery packs 201, and thus improving the installation efficiency of the battery pack 201.

[0066] According to some embodiments of the present invention, referring to Figure 3 , at least one connecting beam 3 is connected between the first mounting portion 11 and the second mounting portion 21. For example, in Figure 3In the example, the left end of the connecting beam 3 is connected to the first mounting portion 11, and the right end of the connecting beam 3 is connected to the second mounting portion 21. With such an arrangement, the connection strength between the first mounting portion 11 and the second mounting portion 21 is strengthened through the connecting beam 3, thereby strengthening the connection strength between the first longitudinal beam 1 and the second longitudinal beam 2, thus improving the structural strength of the vehicle 200 and also improving the service stability of the vehicle frame 100. It should be noted that multiple connecting beams 3 can also be provided, and the multiple connecting beams 3 are arranged at intervals in the front-rear direction. In the description of the present invention, "multiple" means two or more. Among them, the left and right ends of the connecting beam 3 are respectively connected to the first mounting portion 11 and the second mounting portion 21 through a plurality of fasteners 7 (such as bolts or rivets), improving the connection stability.

[0067] According to some embodiments of the present invention, with reference to Figure 11 and Figure 12 , the length of the first mounting portion 11 is at least greater than the width of two battery packs 201 of the corresponding vehicle 200; and / or, the length of the second mounting portion 21 is at least greater than the width of two battery packs 201 of the corresponding vehicle 200.

[0068] For example, the settings of the first mounting portion 11 and the second mounting portion 21 include the following situations: First, only the length of the first mounting portion 11 is at least greater than the width of two battery packs 201 of the corresponding vehicle 200. Second, only the length of the second mounting portion 21 is at least greater than the width of two battery packs 201 of the corresponding vehicle 200. Third, the length of the first mounting portion 11 is at least greater than the width of two battery packs 201 of the corresponding vehicle 200. At the same time, the length of the second mounting portion 21 is at least greater than the width of two battery packs 201 of the corresponding vehicle 200 (such as Figure 11 and Figure 12 ).

[0069] With such an arrangement, it is convenient for two side-by-side battery packs 201 to be placed between two second mounting sections 112 or between two fourth mounting sections 212, thereby ensuring an increase in the number of installed battery packs 201 while reducing the installation difficulty of the battery packs 201, thus improving the installation efficiency of the battery packs 201.

[0070] According to some embodiments of the present invention, with reference to Figure 4 , Figure 5 and Figure 6 , at least a part of the side surface of the first longitudinal beam 1 facing the second longitudinal beam 2 is provided with a first reinforcing beam 8, and the first reinforcing beam 8 and the first longitudinal beam 1 are stacked along the thickness direction of the first longitudinal beam 1; and / or, at least a part of the side surface of the second longitudinal beam 2 facing the first longitudinal beam 1 is provided with a second reinforcing beam (not shown in the figure), and the second reinforcing beam and the second longitudinal beam 2 are stacked along the thickness direction of the second longitudinal beam 2.

[0071] For example, the arrangement of the first reinforcing beam 8 and the second reinforcing beam includes the following cases: First, the first reinforcing beam 8 is provided on at least a part of the side surface of the first longitudinal beam 1 facing the second longitudinal beam 2, and the first reinforcing beam 8 and the first longitudinal beam 1 are stacked along the thickness direction of the first longitudinal beam 1 (as Figure 6 shown). Second, the second reinforcing beam is provided on at least a part of the side surface of the second longitudinal beam 2 facing the first longitudinal beam 1, and the second reinforcing beam and the second longitudinal beam 2 are stacked along the thickness direction of the second longitudinal beam 2. Third, the first reinforcing beam 8 is provided on at least a part of the side surface of the first longitudinal beam 1 facing the second longitudinal beam 2, and the first reinforcing beam 8 and the first longitudinal beam 1 are stacked along the thickness direction of the first longitudinal beam 1. At the same time, the second reinforcing beam is provided on at least a part of the side surface of the second longitudinal beam 2 facing the first longitudinal beam 1, and the second reinforcing beam and the second longitudinal beam 2 are stacked along the thickness direction of the second longitudinal beam 2.

[0072] The cross-sectional shapes of the first longitudinal beam 1, the first reinforcing beam 8, the second longitudinal beam 2, and the second reinforcing beam are approximately "C". The first reinforcing beam 8 is sleeved inside the first longitudinal beam 1 in the left-right direction, and the second reinforcing beam is sleeved inside the second longitudinal beam 2 in the left-right direction. That is, the first longitudinal beam 1 and the second longitudinal beam 2 are channel-shaped, and the first longitudinal beam 1 and the second longitudinal beam 2 are symmetrical in the left-right direction. The first reinforcing beam 8 and the second reinforcing beam extend in the front-back direction respectively. When the first reinforcing beam 8 passes through the first mounting portion 11 of the first longitudinal beam 1, the portion of the first reinforcing beam 8 opposite to the first mounting portion 11 is adapted to the shape of the first mounting portion 11. When the second reinforcing beam passes through the second mounting portion 21 of the second longitudinal beam 2, the portion of the second reinforcing beam opposite to the second mounting portion 21 is adapted to the shape of the second mounting portion. With such an arrangement, the first reinforcing beam 8 strengthens the structural strength of the first longitudinal beam 1, and the second reinforcing beam strengthens the structural strength of the second longitudinal beam 2, thereby improving the structural strength of the vehicle frame 100, increasing the load capacity of the vehicle frame 100, and improving the service performance of the vehicle 200. Among them, the length of the first reinforcing beam 8 is less than the length of the first longitudinal beam 1, and the length of the second reinforcing beam is less than the length of the second longitudinal beam 2, which facilitates the rational use of the first reinforcing beam 8 and the second reinforcing beam, reduces the material consumption of the first reinforcing beam 8 and the second reinforcing beam, and lowers the cost. It should be noted that the first longitudinal beam 1, the first reinforcing beam 8, the second longitudinal beam 2, and the second reinforcing beam are formed into special-shaped structural beams by pressing or rolling.

[0073] Optionally, referring to Figure 1 , the first mounting portion 11 and the second mounting portion 21 jointly define a mounting space 22, and the mounting space 22 is adapted to accommodate a plurality of battery packs 201. For example, when the first mounting portion 11 protrudes in a direction away from the second longitudinal beam 2 and the second mounting portion 21 protrudes in a direction away from the first longitudinal beam 1, the first mounting portion 11 and the second mounting portion 21 jointly define a mounting space 22 (as Figure 1As shown. With such a setting, compared with the prior art, the installation space 22 includes the gap between the first longitudinal beam 1 and the second longitudinal beam 2, increasing the space of the installation space 22 and also improving the space utilization rate on the vehicle frame 100. In addition, it is convenient to place multiple battery packs 201 through the installation space 22, thereby reducing the installation difficulty of the battery packs 201, increasing the number of installed battery packs 201, improving the installation efficiency of the vehicle 200, and also improving the endurance capacity of the vehicle 200.

[0074] Furthermore, referring to Figure 1 , the length of the installation space 22 in the direction perpendicular to the length direction of the first longitudinal beam 1 is at least greater than the lengths of two battery packs 201 of the corresponding vehicle 200. For example, in the example of Figure 1 , the length of the installation space 22 in the left-right direction is greater than the sum of the lengths of the two battery packs 201. With such a setting, when the two battery packs 201 are arranged in the left-right direction, it is effectively ensured that the two battery packs 201 can be placed in the installation space 22, and the installation space 22 is reasonably set, so that it is convenient to install multiple battery packs 201 between the first installation part 11 and the second installation part 21, thereby reducing the installation difficulty of the battery packs 201 and also increasing the number of installed battery packs 201. In addition, by changing the structure of the vehicle frame 100 and the arrangement manner of the battery packs 201, with the vehicle frame 100 of the same length, the number of battery packs 201 is increased, the endurance capacity of the vehicle 200 is improved, the market demand for large-capacity power battery packs 201 is met, and the use efficiency of the vehicle 200 is also improved.

[0075] According to some embodiments of the present invention, referring to Figure 3 and Figure 7 , the connecting beam 3 includes a sub-connecting beam 31 and a plurality of connecting members 32. The sub-connecting beam 31 is located between the first installation part 11 and the second installation part 21, and both ends of the sub-connecting beam 31 are respectively adapted to be connected to the corresponding first installation part 11 and second installation part 21 through the plurality of connecting members 32.

[0076] For example, the cross-sectional shape of the sub-connecting beam 31 is "C" shaped, that is, the sub-connecting beam 31 is a channel-shaped structure. There are four connecting members 32. Two connecting members 32 are respectively connected to the upper and lower sides of the left end of the sub-connecting beam 31, and the other ends of the two connecting members 32 are respectively connected to the upper side and the lower side of the first mounting portion 11. Two connecting members 32 are respectively connected to the upper and lower sides of the right end of the sub-connecting beam 31, and the other ends of the two connecting members 32 are respectively connected to the upper side and the lower side of the second mounting portion 21. With such a setting, the multiple connecting members 32 facilitate the connection between the sub-connecting beam 31 and the first mounting portion 11 and the second mounting portion 21, improving the stability of the sub-connecting beam 31, and thus the stability of the use of the first longitudinal beam 1 and the second longitudinal beam 2. In addition, the sub-connecting beam 31 and the multiple connecting members 32 have a simple structure and are convenient for production, thereby improving the production efficiency of the connecting beam 3. It should be noted that the sub-connecting beam 31 is formed by pressing a steel plate into a channel-shaped structural beam. Between the sub-connecting beam 31 and the multiple connecting members 32, and between the multiple connecting members 32 and the first mounting portion 11 and the second mounting portion 21, they are connected by a plurality of fasteners 7.

[0077] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 , between the positions of the first longitudinal beam 1 except the first mounting portion 11 and the second longitudinal beam 2 except the second mounting portion 21, there are a plurality of fixed beams 4. The plurality of fixed beams 4 include a plurality of first fixed beams 41 and second fixed beams 42. The plurality of first fixed beams 41 are arranged at intervals in the front-rear direction, and the second fixed beam 42 is located at the rear end of the vehicle frame 100.

[0078] Among them, the first fixed beam 41 includes a first sub-fixed beam 411 and four first connecting members 412. The first sub-fixed beam 411 is located between the first longitudinal beam 1 and the second longitudinal beam 2. The two ends of the first sub-fixed beam 411 are respectively adapted to be connected to the side surfaces of the corresponding first longitudinal beam 1 and the second longitudinal beam 2 through two first sub-connecting members 32. The side surface of the first connecting member 412 is provided with holes for connecting to the first longitudinal beam 1 or the second longitudinal beam 2.

[0079] The second fixed beam 42 includes a second sub-fixed beam 421, a third sub-fixed beam 422, two second connectors 423 and two third connectors 424. The second sub-fixed beam 421 and the third sub-fixed beam 422 are located between the first longitudinal beam 1 and the second longitudinal beam 2. The second sub-fixed beam 421 and the third sub-fixed beam 422 are arranged back to back. The upper sides of the two ends of the second sub-fixed beam 421 and the third sub-fixed beam 422 are adapted to be respectively connected to the upper ends of the sides of the first longitudinal beam 1 and the second longitudinal beam 2 through the two second connectors 423, and the lower sides of the two ends of the second sub-fixed beam 421 and the third sub-fixed beam 422 are adapted to be respectively connected to the lower ends of the sides of the first longitudinal beam 1 and the second longitudinal beam 2 through the two third connectors 424. The lengths of the second connectors 423 and the third connectors 424 are greater than the length of the first connector 412. Holes for connecting to the first longitudinal beam 1 or the second longitudinal beam 2 are provided on the sides of the second connectors 423 and the third connectors 424.

[0080] With such an arrangement, the setting of multiple first fixed beams 41 and second fixed beams 42 further strengthens the connection strength between the first longitudinal beam 1 and the second longitudinal beam 2, thereby further improving the service stability of the first longitudinal beam 1 and the second longitudinal beam 2, enhancing the structural strength of the vehicle frame 100, and further improving the service performance of the vehicle frame 100. In addition, the second connectors 423 and the third connectors 424 increase the contact area between the second fixed beam 42 and the first longitudinal beam 1 and the second longitudinal beam 2, thereby improving the supporting effect of the second fixed beam 42 on the vehicle frame 100, enhancing the flow disturbance effect, and further improving the service performance of the vehicle frame 100. Moreover, the structures of the first fixed beam 41 and the second fixed beam 42 are simple and easy to produce. It should be noted that the multiple fixed beams 4 further include a tail fixed beam 43. The tail fixed beam 43 includes a sub-tail fixed beam 431 and multiple fourth connectors 432. The left and right ends of the sub-tail fixed beam 431 are respectively connected to the rear ends of the corresponding first longitudinal beam 1 and the second longitudinal beam 2 through the fourth connectors 432. Holes for connecting to the first longitudinal beam 1 or the second longitudinal beam 2 are provided on the sides of the fourth connectors 432, further improving the connection stability between the first longitudinal beam 1 and the second longitudinal beam 2. The sub-tail fixed beam 431 is formed into a channel beam structure by pressing a steel plate. Among them, the left end of the fixed beam 4 is connected to the first longitudinal beam 1 and the first reinforcing beam 8 through a fastener 7, and the right end of the fixed beam 4 is connected to the second longitudinal beam 2 and the second reinforcing beam through a fastener 7.

[0081] Optionally, referring to Figure 1, the vehicle frame 100 includes a plurality of first connecting plates 5 and a plurality of second connecting plates 6. At least one of the plurality of first connecting plates 5 is located on the side of the first longitudinal beam 1 away from the second fixed beam 42, and at least one of the plurality of first connecting plates 5 is located on the side of the second longitudinal beam 2 away from the second fixed beam 42. At least one of the plurality of second connecting plates 6 is located on the side of the second longitudinal beam 2 away from the second fixed beam 42, and at least one of the plurality of second connecting plates 6 is located on the side of the first longitudinal beam 1 away from the second fixed beam 42. The first connecting plates 5 and the second connecting plates 6 are arranged at intervals in the front-rear direction. For example, in Figure 1 In the example, there are two first connecting plates 5. One of the first connecting plates 5 is located on the side of the first longitudinal beam 1 away from the second fixed beam 42, and the other first connecting plate 5 is located on the side of the second longitudinal beam 2 away from the second fixed beam 42. The two first connecting plates 5 are opposite to each other in the left-right direction. There are two second connecting plates 6. One of the second connecting plates 6 is located on the side of the first longitudinal beam 1 away from the second fixed beam 42, and the other second connecting plate 6 is located on the side of the second longitudinal beam 2 away from the second fixed beam 42. The two second connecting plates 6 are opposite to each other in the left-right direction. With such an arrangement, other components of the vehicle 200 can be avoided between the first connecting plate 5 and the second connecting plate 6, so as to facilitate the assembly of other components of the vehicle 200 with the vehicle frame 100, thereby improving the service performance of the vehicle frame 100. However, it is not limited to this. It should be noted that the number and arrangement mode of the first connecting plates 5 and the second connecting plates 6 can be specifically set according to the actual use situation. The above connections can all be connected by a plurality of fasteners 7.
