[0062] In some embodiments of the present application, the battery 200 can not only serve as the operating power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0063] In some embodiments, the vehicle 1000 may also include a frame assembly 100. The functions of the frame assembly 100 include supporting and connecting the various assemblies of the vehicle 1000, so that the various assemblies maintain a relatively correct position, and withstand various loads inside and outside the vehicle 1000, and are used to mount the battery 200 to achieve battery replacement of the vehicle 1000.

[0066] In some embodiments, the vehicle frame 10 may be a frame structure straddling the front and rear axles of the vehicle 1000, commonly known as a beam, and is the base of the vehicle 1000. The functions of the vehicle frame 10 may include supporting and connecting the various assemblies of the vehicle 1000, so that the various assemblies maintain a relatively correct position, and bear various loads inside and outside the vehicle 1000. In some embodiments, the vehicle frame 10 may include a pair of longitudinal beams, such as a first longitudinal beam 111 and a second longitudinal beam 112. Along the transverse direction y of the vehicle frame, the first longitudinal beam 111 and the second longitudinal beam 112 are arranged with a relative interval. The first longitudinal beam 111 and the second longitudinal beam 112 may extend along the longitudinal direction x of the vehicle frame, that is, the longitudinal direction of the longitudinal beam is parallel to the longitudinal beam of the vehicle frame 10. In some examples, the vehicle frame 10 also includes a cross beam 110, which is arranged between the first longitudinal beam 111 and the second longitudinal beam 112 and connects the first longitudinal beam 111 and the second longitudinal beam 112.

[0067] In some embodiments, the first bracket 20 and the second bracket 30 are components fixed to the frame 10, and the first bracket 20 and the second bracket 30 are respectively located on the outside of the frame 10. Figure 2 , the first bracket 20 is connected to the first longitudinal beam 111 and is located on the side of the first longitudinal beam 111 away from the second longitudinal beam 112, and the second bracket 30 is connected to the second longitudinal beam 112 and is located on the side of the second longitudinal beam 112 away from the first longitudinal beam 111. In some embodiments, the first bracket 20 and the second bracket 30 can be connected to the frame 10 by welding, riveting, threading, etc. In other embodiments, the first bracket 20 and / or the second bracket 30 can be integrally formed with the frame 10.

[0068] In some embodiments, the materials of the first bracket 20 and the second bracket 30 may be the same as or different from the material of the frame 10. In some embodiments, the materials of the first bracket 20 and the second bracket 30 may be aluminum alloy, steel, cast iron or reinforced plastic.

[0069] In some embodiments, along the gravity direction z, the first bracket 20 and the second bracket 30 may not extend beyond the frame 10, for example, the lowest end of the first bracket 20 and the lowest end of the second bracket 30 are not lower than the lowest end of the frame 10, or the lowest end of the first bracket 20 and the lowest end of the second bracket 30 are located above the lowest end of the frame 10. In other embodiments, along the gravity direction z, the first bracket 20 and the second bracket 30 may extend beyond the frame 10.

[0070] The mounting part 40 is used to realize the detachable connection between the battery 200 and the frame assembly 100. The mounting part 40 is a unit in groups, and each group of mounting parts 40 can be detachably connected to a battery 200. If there are multiple groups of mounting parts 40 on the frame assembly 100, it can be understood that the frame assembly 100 can mount a corresponding number of batteries 200. For example, if there are three groups of mounting parts 40 on the frame assembly 100, the maximum number of batteries 200 mounted on the frame assembly 100 is three. It can be understood that the number of batteries 200 mounted on the frame assembly 100 can be less than the number of groups of mounting parts 40 or equal to the number of groups of mounting parts 40 according to needs.

[0071] In some embodiments, the mounting portion 40 includes but is not limited to mounting holes, mounting screws, and other structures that can achieve detachable connection with the battery 200 provided on the frame assembly 100. Exemplarily, the mounting portion 40 is a mounting hole provided on the frame assembly 100, and the battery 200 is provided with a locking structure, which can pass through the mounting hole and be locked to the frame assembly 100. Another exemplary embodiment, the mounting portion 40 is a mounting screw or other locking structure provided on the frame 10, and the battery 200 is provided with a hole structure, and the locking structure can pass through the hole structure to lock the battery 200.

[0072] “Each group of mounting parts 40 includes a first mounting part 41 arranged on the first bracket 20, a second mounting part 42 arranged on the second bracket 30, and a third mounting part 43 arranged on the cross beam 110” can be understood as dividing each group of mounting parts 40 into three parts, including a first mounting part 41 arranged on the first bracket 20, a second mounting part 42 arranged on the second bracket 30, and a third mounting part 43 arranged on the cross beam 110, so that the mounting points of the battery 200 and the frame assembly 100 are distributed on the first bracket 20, the second bracket 30 and the cross beam 110.

[0073] In the above scheme, by setting part of the mounting portion 40 on the cross beam 110, the bracket and the frame 10 can jointly mount the battery 200, which can effectively reduce the mounting load of the bracket, thereby reducing the parts of the bracket. On the one hand, it saves the material cost of the bracket, which is beneficial to the control of the manufacturing cost of the vehicle 1000. On the other hand, it reduces the impact on the quality of the vehicle 1000, which is beneficial to the improvement of the endurance of the vehicle 1000.

[0074] According to some embodiments of the present application, along the gravity direction z, the first bracket 20 and the second bracket 30 do not extend beyond the frame 10 .

[0075] “Along the gravity direction z, the first bracket 20 and the second bracket 30 do not extend beyond the frame 10” can be understood as, when the vehicle 1000 having the frame assembly 100 is supported on the ground, the distance between the frame 10 and the ground is greater than or equal to the distance between the first bracket 20 and the ground, and greater than or equal to the distance between the second bracket 30 and the ground.

[0076] In some embodiments, the bracket may include a bracket upper wing plate, a bracket web plate, and a bracket lower wing plate. Along the gravity direction z, the bracket upper wing plate is arranged at the upper end of the bracket web plate, and the bracket lower wing plate is arranged at the upper end of the bracket web plate. The bracket upper wing plate and the bracket lower wing plate are bent toward the inside of the vehicle frame 10. For example, the first bracket 20 may include a first bracket 20 upper wing plate, a first bracket 20 web plate, and a first bracket 20 lower wing plate. The second bracket 30 may include a second bracket 30 upper wing plate, a second bracket 30 web plate, and a second bracket 30 lower wing plate. The end of the cross beam 110 may be connected to the inner side of the first bracket 20 web plate and the second bracket 30 web plate. Along the gravity direction z, the cross beam 110 is located between the bracket upper wing plate and the bracket lower wing plate. The lowest parts of the first bracket 20 and the second bracket 30 in the gravity direction z do not exceed the lower wing plate of the first bracket 20 and the lower wing plate of the second bracket 30. For example, the first bracket 20 and the second bracket 30 are located above the lower wing plate of the first bracket 20 and the lower wing plate of the second bracket 30.

[0077] In some embodiments, along the gravity direction z, and the direction opposite to the gravity direction z, the first bracket 20 and the second bracket 30 do not extend beyond the frame 10. It can be understood that along the side-by-side direction of the first longitudinal beam 111 and the second longitudinal beam 112, that is, along the lateral direction y of the frame, the orthographic projection of the first bracket 20 and the orthographic projection of the second bracket 30 can be covered by the orthographic projection of the first longitudinal beam 111, and can also be covered by the orthographic projection of the second longitudinal beam 112.

[0078] In the above scheme, by setting the third mounting portion 43 on the cross beam 110 and ensuring that the first bracket 20 and the second bracket 30 do not exceed the frame 10 in the gravity direction z, the influence of the bracket on the ground clearance of the vehicle 1000 can be reduced, which is beneficial to improving the driving performance of the vehicle 1000.

[0079] According to some embodiments of this application, see Figure 5 The cross beam 110 includes a cross beam web 1100 and a cross beam lower wing plate 1101 . Along the thickness direction of the cross beam web 1100 , the cross beam lower wing plate 1101 is protruded from the cross beam web 1100 , and the third mounting portion 43 is disposed on the cross beam lower wing plate 1101 .

[0080] In some embodiments, the cross beam 110 includes a cross beam web 1100 extending transversely along the vehicle frame 10. Along the gravity direction z, a cross beam lower wing plate 1101 is provided at the lower end of the cross beam web 1100, and the cross beam lower wing plate 1101 protrudes from the cross beam web 1100 in the thickness direction of the cross beam web 1100. In some embodiments, the cross beam 110 also includes a cross beam upper wing plate 1102, which is provided at the upper end of the cross beam web 1100, and the protruding direction of the cross beam upper wing plate 1102 relative to the cross beam web 1100 is consistent with the protruding direction of the cross beam lower wing plate 1101.

[0081] In some embodiments, the third mounting portion 43 can be arranged on the lower wing plate 1101 of the beam. For example, the third mounting portion 43 is a mounting hole that passes through the lower wing plate 1101 of the beam along the gravity direction z, or other locking structures such as mounting screws arranged on the lower wing plate 1101 of the beam.

[0082] In the above scheme, by protruding a lower wing plate 1101 of the crossbeam on the web 1100 of the crossbeam, and arranging the third mounting portion 43 on the lower wing plate 1101 of the crossbeam, the battery 200 can be conveniently mounted on the crossbeam 110, and the crossbeam 110 is evenly stressed, so that the connection relationship between the battery 200 and the frame assembly 100 is stable, reducing the risk of the battery 200 falling off.

[0083] In other embodiments, the third mounting portion 43 may also be disposed on the cross beam web 1100 . For example, the third mounting portion 43 is a mounting screw or other locking structure disposed on the cross beam web 1100 and facing the ground.

[0084] In other embodiments, the cross beam 110 may not include the cross beam lower wing plate 1101, and the cross beam 110 may be a tubular structure, a flat plate structure, or a rod-shaped structure.

[0085] According to some embodiments of the present application, the crossbeam 110 further includes a reinforcing plate 1103 , which is disposed on the upper surface of the lower wing plate 1101 of the crossbeam, and the third mounting portion 43 includes a third mounting hole 430 that passes through the reinforcing plate 1103 and the lower wing plate 1101 of the crossbeam.

[0086] In some embodiments, the reinforcing plate 1103 is a reinforcing structural member disposed on the lower wing plate 1101 of the cross beam, and the reinforcing plate 1103 can be connected to the lower wing plate 1101 of the cross beam by welding, bonding, riveting, clamping, screw connection or contact connection.

[0087] In some embodiments, the manufacturing material of the reinforcement plate 1103 includes but is not limited to aluminum, aluminum alloy, steel, reinforced plastic, etc.

[0088] In some embodiments, a plurality of third mounting holes 430 are provided on the lower wing plate 1101 of the cross beam, and the number of the reinforcing plates 1103 may be one or correspond to the number of the third mounting holes 430. For example, the number of the reinforcing plates 1103 is one, and the one reinforcing plate 1103 is provided on the upper surface of the lower wing plate 1101 of the cross beam, and the one reinforcing plate 1103 is provided with through holes corresponding to the number of the third mounting holes 430, and the through holes are connected to the corresponding third mounting holes 430. For another example, the number of the reinforcing plates 1103 is multiple and corresponds to the third mounting holes 430 one by one.

[0089] In some embodiments, the third mounting portion 43 includes a third mounting hole 430 that passes through the lower wing plate 1101 of the cross beam, and the reinforcing plate 1103 can be arranged around the third mounting hole 430 and located on the upper surface of the lower wing plate 1101 of the cross beam. Exemplarily, when the locking structure of the battery 200 passes through the third mounting hole 430, the locking structure can overlap the surface of the reinforcing plate 1103.

[0090] In the above solution, by providing a reinforcing plate 1103 on the lower wing plate 1101 of the cross beam, the structural strength of the lower wing plate 1101 of the cross beam can be effectively improved, and the risk of the battery 200 being separated from the lower wing plate 1101 of the cross beam can be reduced, thereby improving the driving reliability of the vehicle 1000.

[0091] In some embodiments, the structural shape of the lower wing plate 1101 of the cross beam may also be designed, for example, reinforcing ribs and a concave-convex structure may be provided on the lower wing plate of the cross beam 110 to improve the structural strength of the lower wing plate 1101 of the cross beam itself.

[0092] According to some embodiments of this application, see Figure 4 The first bracket 20 has a plurality of first accommodating spaces 51, which are arranged along the longitudinal direction x of the frame. The second bracket 30 has a plurality of second accommodating spaces 52, which are arranged along the longitudinal direction x of the frame. A plurality of cross beams 110 are provided, which are arranged at intervals along the longitudinal direction x of the frame, and a third accommodating space 53 is formed between two adjacent cross beams 110. The first accommodating space 51, the second accommodating space 52 and the third accommodating space 53 correspond to each other one by one, and each first accommodating space 51, a second accommodating space 52 corresponding to the first accommodating space 51, and a third accommodating space 53 corresponding to the first accommodating space 51 together accommodate a battery 200.

[0093] In some embodiments, the first bracket 20 has a plurality of first accommodating spaces 51, and the second bracket 30 correspondingly has a plurality of second accommodating spaces 52, and a plurality of third accommodating spaces 53 are formed between the corresponding plurality of cross beams 110. The first accommodating spaces 51, the second accommodating spaces 52, and the third accommodating spaces 53 correspond to each other, and each corresponding first accommodating space 51, the second accommodating space 52, and the third accommodating space 53 together constitute a main space 50 capable of accommodating a battery 200, and the plurality of main spaces 50 are arranged along the longitudinal direction x of the frame, so that the frame assembly 100 can mount a plurality of batteries 200, and the batteries 200 can be arranged along the longitudinal direction x of the frame.

[0094] In some embodiments, the first accommodating space 51, the second accommodating space 52 and the third accommodating space 53 can be understood as that at least a portion of the battery 200 is accommodated by the first accommodating space 51, the second accommodating space 52 and the third accommodating space 53, and along the lateral direction y of the frame, the orthographic projection of at least a portion of the battery 200 can at least partially overlap with the frame 10, the first bracket 20 and the second bracket 30.

[0095] In some embodiments, the sizes of the plurality of main spaces 50 may be the same, so that a plurality of batteries 200 of the same specifications can be mounted. In other embodiments, the sizes of the main spaces 50 may be different, so that a plurality of batteries 200 of different specifications can be mounted.

[0096] exist Figure 4 Three areas are shown with dotted lines, each area corresponds to a main space 50, and each main space 50 can accommodate a battery 200.

[0097] In some embodiments, the first accommodating space 51 , the second accommodating space 52 and the third accommodating space 53 all have openings open downward, that is, the main space 50 has an opening open downward, and the opening is used for part of the battery 200 to enter or leave the main space 50 .

[0098] Exemplarily, the main space 50 has an opening facing the ground. When the vehicle 1000 is supported on the ground, the opening of the main space 50 faces the ground, and the battery 200 can be loaded into the main space 50 from bottom to top, or can be removed from the main space 50 from top to bottom.

[0099] In the above scheme, the first bracket 20, the second bracket 30 and the multiple cross beams 110 respectively form multiple first accommodating spaces 51, the second accommodating spaces 52 and the third accommodating spaces 53, and the first accommodating spaces 51, the second accommodating spaces 52 and the third accommodating spaces 53 can correspond one to one to accommodate multiple batteries 200, so that the frame assembly 100 can mount multiple batteries 200, thereby effectively improving the endurance of the vehicle 1000.

[0100] According to some embodiments of this application, see Figure 2 , Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the first sub-bracket 21 in some embodiments of the present application. Figure 7 Schematic diagram of the second sub-bracket 31 in some embodiments of the present application.

[0101] The first bracket 20 includes a plurality of first sub-brackets 21 , which are arranged along the longitudinal direction x of the frame. Each first sub-bracket 21 has a first accommodating space 51 , and each first sub-bracket 21 is connected to the first longitudinal beam 111 .

[0102] The second bracket 30 includes a plurality of second sub-brackets 31 , which are arranged along the longitudinal direction x of the frame. Each second sub-bracket 31 has a second accommodating space 52 , and each second sub-bracket 31 is connected to the second longitudinal beam 112 .

[0103] In some embodiments, the first bracket 20 includes a plurality of first sub-brackets 21, and the plurality of first sub-brackets 21 may be independent of each other, and each first sub-bracket 21 has a first accommodating space 51, and each first sub-bracket 21 may be connected to the first longitudinal beam 111, respectively. Each sub-bracket may be fixedly connected to the first longitudinal beam 111 or detachably connected. In some embodiments, the connection relationship between each first sub-bracket 21 and the first longitudinal beam 111 includes but is not limited to welding, riveting, clamping, screw connection, etc. Exemplarily, the first sub-bracket 21 is a first frame structure, and the first frame structure includes a plurality of structural members, and the plurality of structural members are spliced ​​together to enclose the first accommodating space 51, and the first mounting portion 41 may be provided on one or more structural members.

[0104] In some embodiments, the second bracket 30 includes a plurality of second sub-brackets 31, and the plurality of second sub-brackets 31 may be independent of each other, and each second sub-bracket 31 has a second accommodating space 52, and each second sub-bracket 31 may be connected to the second longitudinal beam 112, respectively. Every two sub-brackets may be fixedly connected or detachably connected to the second longitudinal beam 112. In some embodiments, the connection relationship between each second sub-bracket 31 and the second longitudinal beam 112 includes but is not limited to welding, riveting, clamping, screw connection, etc. Exemplarily, the second sub-bracket 31 is a second frame structure, and the second frame structure includes a plurality of structural members, and the plurality of structural members are spliced ​​together to enclose the second accommodating space 52, and the second mounting portion 42 may be provided on one or more structural members.

[0105] In the above scheme, by setting up multiple first sub-brackets 21 and multiple second sub-brackets 31 to respectively accommodate the batteries 200, the bracket can be modularized, so that different numbers of first sub-brackets 21 and second sub-brackets 31 can be removed or installed as needed, so that the operating cost of the vehicle 1000 can be controlled according to demand.

[0106] In other embodiments, the first bracket 20 may include a plurality of mounting structures arranged at intervals along the longitudinal direction of the frame 10, and the first accommodating space 51 is defined between two adjacent mounting structures. Unlike the first sub-bracket 21 described above, there is a shared mounting structure between two connected first accommodating spaces 51, which has the technical effect of saving material costs. Similarly, in other embodiments, the second bracket 30 may include a plurality of mounting structures arranged at intervals along the longitudinal direction of the frame 10, and the second accommodating space 52 is defined between two adjacent mounting structures. Unlike the second sub-bracket 31 described above, there is a shared mounting structure between two connected second accommodating spaces 52, which has the technical effect of saving material costs.

[0107] According to some embodiments of the present application, each second sub-bracket 31 is detachably connected to the first longitudinal beam 111 , and each second sub-bracket 31 is detachably connected to the second longitudinal beam 112 .

[0108] In some embodiments, each first sub-bracket 21 is detachably connected to the first longitudinal beam 111. In some embodiments, the first sub-bracket 21 and the first longitudinal beam 111 can be connected by a detachable structure or combination. For example, the first sub-bracket 21 is fixed to the first longitudinal beam 111 by a screw. When the first sub-bracket 21 needs to be removed from the first longitudinal beam 111, it can be achieved by twisting the screw. For example, a support structure is included between the first sub-bracket 21 and the first longitudinal beam 111. For example, the first longitudinal beam 111 is formed with a support plate, and the first sub-bracket 21 is directly placed on the support plate, and the support plate overcomes the gravity of the first sub-bracket 21. The first sub-bracket 21 and the first longitudinal beam 111 are locked by the screw to achieve mutual fixation between the first sub-bracket 21 and the first longitudinal beam 111. When the first sub-bracket 21 needs to be removed from the first longitudinal beam 111, the screw is first removed to release the locking relationship between the first sub-bracket 21 and the first longitudinal beam 111, and then the first sub-bracket 21 can be carried away from the support plate of the first longitudinal beam 111.

[0109] In some embodiments, each second sub-bracket 31 is detachably connected to the second longitudinal beam 112. In some embodiments, the second sub-bracket 31 and the second longitudinal beam 112 can be connected by a detachable structure or combination. For example, the second sub-bracket 31 is fixed to the second longitudinal beam 112 by a screw. When the second sub-bracket 31 needs to be removed from the second longitudinal beam 112, it can be achieved by twisting the screw. For example, a support structure is included between the second sub-bracket 31 and the second longitudinal beam 112. For example, the second longitudinal beam 112 is formed with a support plate, and the second sub-bracket 31 is directly placed on the support plate, and the support plate overcomes the gravity of the second sub-bracket 31. The second sub-bracket 31 and the second longitudinal beam 112 are locked by the screw to achieve the mutual fixation of the second sub-bracket 31 and the second longitudinal beam 112. When the second sub-bracket 31 needs to be removed from the second longitudinal beam 112, the screw is first removed to release the locking relationship between the second sub-bracket 31 and the second longitudinal beam 112, and then the second sub-bracket 31 can be carried away from the support plate of the second longitudinal beam 112.

[0110] In some embodiments, since the first sub-bracket 21 and the second sub-bracket 31 can be removed from the frame 10, when the vehicle 1000 has the frame assembly 100, the number of sub-brackets mounted on the frame 10 can be selected according to actual conditions. For example, when the vehicle 1000 only needs one battery 200, the redundant first sub-brackets 21 and second sub-brackets 31 of the frame 10 can be removed, and the corresponding first sub-bracket 21 and second sub-bracket 31 can be retained to cooperate with the crossbeam 110 to mount a battery 200.

[0111] In the above scheme, by setting the first sub-bracket 21 and the second sub-bracket 31 to be detachably connected to the longitudinal beam, it is convenient for the user to selectively remove or install different numbers of brackets according to the endurance requirements of the vehicle 1000, so that the operating cost of the vehicle 1000 can be accurately controlled according to demand.

Exemplarily, the second mounting portion 42 includes a second mounting hole 420 arranged on one of the second mounting beams 32, and a second mounting hole 420 arranged on the other second mounting beam 32. In some embodiments, each second mounting beam 32 is provided with two second mounting holes 420, and the two second mounting holes 420 are arranged at intervals along the transverse direction y of the frame.

[0117] In the above scheme, by setting two side-by-side first mounting beams 22, the first sub-bracket 21 can be evenly loaded with force to mount the battery 200, and by setting two side-by-side second mounting beams 32, the second sub-bracket 31 can be evenly loaded with force to mount the battery 200, thereby improving the connection stability between the battery 200 and the frame assembly 100 and reducing the risk of the battery 200 falling off.
