[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 1-7 The vehicle frame 100 according to an embodiment of the present utility model is described. The vehicle frame 100 can be applied to a vehicle 1000.

[0022] Combination Figures 1-7 As shown, the frame 100 according to this utility model mainly includes: longitudinal beams 10, crossbeams 20 and battery mounting brackets 30.

[0023] The longitudinal beam 10 extends in the front-rear direction and includes a first longitudinal beam 101 and a second longitudinal beam 102, which are spaced apart in the left-right direction. Specifically, the longitudinal beam 10 can not only bear the weight of the vehicle body and some components, but also improve the torsional stiffness and deformation resistance of the frame 100. Moreover, the spaced arrangement of the first longitudinal beam 101 and the second longitudinal beam 102 in the left-right direction can not only provide balanced support for the left and right sides of the vehicle body, which can help prevent body roll, but also provide installation space for some components through the gap between the first longitudinal beam 101 and the second longitudinal beam 102.

[0024] Moreover, the crossbeam 20 extends in the left and right direction and connects between the first longitudinal beam 101 and the second longitudinal beam 102. The crossbeam 20, the first longitudinal beam 101 and the second longitudinal beam 102 together form a stable frame of the vehicle frame 100, which can not only further improve the torsional stiffness and deformation resistance of the vehicle frame 100 and prevent the vehicle frame 100 from deforming, but also provide more uniform support for the vehicle body and provide reliable installation positions for some components.

[0025] Furthermore, the battery mounting bracket 30 extends in the left-right direction, connecting between the first longitudinal beam 101 and the second longitudinal beam 102 and forming a battery mounting groove 50, which is suitable for mounting the battery 60. Specifically, the battery mounting bracket 30 cooperates with the first longitudinal beam 101 and the second longitudinal beam 102, not only transferring the weight of the battery 60 to the vehicle frame 100 to support the weight of the battery 60 and provide a mounting base for the battery 60, but also forming the battery mounting groove 50 to provide mounting space for the battery 60. Moreover, since the battery 60 is located in the area between the first longitudinal beam 101 and the second longitudinal beam 102, when the vehicle 1000 is involved in a collision, the first longitudinal beam 101 and the second longitudinal beam 102 can absorb a large amount of collision energy, reducing the impact force transmitted to the battery 60 and improving the stability and reliability of the battery 60.

[0026] Furthermore, the battery mounting bracket 30 and the crossbeam 20 are spaced apart in the front-to-back direction. Specifically, the battery mounting bracket 30 can be used to mount the battery 60, and the crossbeam 20 can be used to mount other components. The spaced-apart arrangement between the battery mounting bracket 30 and the crossbeam 20 in the front-to-back direction prevents structural interference between the battery 60 and other components, and prevents difficulties in mounting other components due to the installation of the battery 60, or vice versa. This provides sufficient mounting space for the battery 60, facilitating its installation and removal.

[0027] Furthermore, in the prior art, the central motor of the electric tractor is installed in the middle or front of the frame 100, and the vehicle 1000 is equipped with a drive shaft. Compared with the prior art, the embodiment of this utility model is applicable to electric tractors with electric drive axles as the core drive technology. The motor in the vehicle 1000 is located inside the axle, eliminating the need for a drive shaft to transmit power. This allows the space in the existing vehicle 1000 where the central motor and drive shaft are located to be used to arrange the battery 60. This not only ensures that there is enough space for the battery 60, which is beneficial to increasing the total capacity of the battery 60 that the vehicle 1000 can carry and improving the range of the vehicle 1000, but also eliminates the need to find new space to arrange the battery 60, saving space and improving the space utilization and structural compactness of the vehicle 1000. In addition, it can also reduce the wheelbase of the vehicle 1000 and improve the maneuverability of the vehicle 1000.

[0028] Therefore, by connecting the battery mounting bracket 30 between the first longitudinal beam 101 and the second longitudinal beam 102 and forming a battery mounting groove 50 for mounting the battery 60, the space in the existing vehicle 1000 used for setting the central motor and drive shaft can be used to form the battery mounting groove 50. This not only ensures that there is enough space for the battery 60, which is beneficial to increasing the total capacity of the battery 60 that the vehicle 1000 can carry and improving the range of the vehicle 1000, but also eliminates the need to find new space to arrange the battery 60, saving space and improving the space utilization and structural compactness of the vehicle 1000. In addition, it can also reduce the wheelbase of the vehicle 1000 and improve the maneuverability of the vehicle 1000.

[0029] Combination Figure 1 , Figure 2 and Figure 7 As shown, the battery mounting bracket 30 is positioned near the front end of the longitudinal beam 10 and spaced apart on the front side of the crossbeam 20. Specifically, by positioning the battery mounting bracket 30 near the front end of the longitudinal beam 10 and spaced apart on the front side of the crossbeam 20, the space in the existing vehicle 1000 used for the central motor and drive shaft can be effectively utilized to arrange the battery 60 of this application. This requires minimal modification to the existing vehicle 1000 structure, which helps reduce the modification cost of the vehicle 1000. It also saves layout space and improves the space utilization and structural compactness of the vehicle 1000.

[0030] Furthermore, the front sides of the battery mounting bracket 30 area and the crossbeam 20 arrangement area are spaced apart from each other, which can prevent the battery 60 from interfering with other components, prevent the installation of other components from being difficult due to the installation of the battery 60, or prevent the installation of the battery 60 from being difficult due to the installation of other components, thereby providing sufficient installation space for the battery 60 and facilitating the installation and removal of the battery 60.

[0031] Combination Figure 1 , Figure 2 and Figure 7 As shown, there are multiple battery mounting brackets 30, which are spaced apart in the front-to-back direction, and each bracket forms a multiple battery mounting slot 50. Specifically, the spaced arrangement of the multiple battery mounting brackets 30 in the front-to-back direction not only allows for the formation of multiple spaced battery mounting slots 50 to efficiently arrange multiple batteries 60 within a limited space, but also provides uniform and stable support for the batteries 60, thereby improving the stability and reliability of the batteries 60.

[0032] Moreover, by using multiple battery mounting slots 50 to install multiple batteries 60 instead of a single large battery module, when a battery 60 fails, it is not necessary to disassemble and replace the entire battery module. Instead, the faulty battery 60 can be located, replaced, or repaired, which can reduce the maintenance cost and time of the battery 60 within 1,000 kilometers of the vehicle.

[0033] Combination Figures 1-7 As shown, the battery mounting bracket 30 includes a first battery mounting bracket 301, which includes a first sub-bracket 401. The first sub-bracket 401 includes a first bracket segment 4011, a second bracket segment 4012, and a third bracket segment 4013. The first bracket segment 4011 and the second bracket segment 4012 both extend in the vertical direction. The third bracket segment 4013 is connected between the lower end of the first bracket segment 4011 and the lower end of the second bracket segment 4012. The upper end of the first bracket segment 4011 and the upper end of the second bracket segment 4012 are respectively connected to the first longitudinal beam 101 and the second longitudinal beam 102. The first sub-bracket 401, the first longitudinal beam 101, and the second longitudinal beam 102 together form a first battery mounting groove 501.

[0034] Specifically, the first support segment 4011 and the second support segment 4012 both extend in the vertical direction. The upper end of the first support segment 4011 is connected to the first longitudinal beam 101, and the upper end of the second support segment 4012 is connected to the second longitudinal beam 102. The third support segment 4013 extends in the horizontal direction and connects between the lower ends of the first support segment 4011 and the second support segment 4012. In this way, the third support segment 4013 can provide support and fixation for the bottom of the battery 60. The first support segment 4011 and the second support segment 4012 can transfer the force on the third support segment 4013 to the longitudinal beam 10, thereby providing stable support for the battery 60 and improving the stability and reliability of the battery 60.

[0035] Moreover, the first sub-bracket 401, the first longitudinal beam 101, and the second longitudinal beam 102 together enclose and form the first battery mounting groove 501. This not only provides installation space for the battery 60, but also provides good positioning and protection for the battery 60, preventing the battery 60 from shifting during the driving of the vehicle 1000. At the same time, it also facilitates the installation and removal of the battery 60.

[0036] Furthermore, both the upper ends of the first support segment 4011 and the second support segment 4012 are provided with a first connecting segment extending in the left-right direction. The first connecting segment has a fixing hole, and the longitudinal beam 10 has a mounting hole corresponding to the position where the first sub-support 401 is connected. The fixing hole and the mounting hole correspond in shape and size. Fasteners are sequentially inserted through the fixing hole and the mounting hole to connect and fix the first sub-support 401 and the longitudinal beam 10. This not only makes the connection between the first sub-support 401 and the longitudinal beam 10 simple, direct, stable, and reliable, but also facilitates the installation and disassembly of the first sub-support 401, thereby facilitating the installation and disassembly of the battery 60 in the first battery mounting slot 501. The fixing hole and the mounting hole can be threaded holes, and the fastener can be a screw.

[0037] In some embodiments of this utility model, the first sub-support 401 can be an integrally formed structural component, which can improve the overall structural strength and rigidity of the first sub-support 401, reduce the assembly gap between each support segment, avoid stress concentration caused by splicing between each support segment, and thus ensure the stability and safety of the first battery mounting groove 501 when bearing the weight of the battery 60.

[0038] In some embodiments of this utility model, the first support segment 4011 and the second support segment 4012 are not completely perpendicular to the third support segment 4013. The included angles formed between the first support segment 4011, the second support segment 4012, and the third support segment 4013 are equal and both greater than 90 degrees. The included angles formed between the first support segment 4011, the second support segment 4012, and the third support segment 4013 can be adjusted according to the specific stability requirements of the first sub-support 401, the arrangement space within the vehicle 1000, and the specific structure of the vehicle 1000.

[0039] Combination Figures 1-7 As shown, the first battery mounting bracket 301 also includes a second sub-bracket 402. The second sub-bracket 402 is located above the first sub-bracket 401 and includes a fourth bracket segment 4021, a fifth bracket segment 4022, and a sixth bracket segment 4023. The fourth bracket segment 4021 and the fifth bracket segment 4022 extend downward at an angle, and their lower ends gradually approach each other in the left-right direction. The sixth bracket segment 4023 is connected between the fourth bracket segment 4021 and the fifth bracket segment 4022. The upper ends of the fourth bracket segment 4021 and the fifth bracket segment 4022 are respectively connected to the first longitudinal beam 101 and the second longitudinal beam 102. The second sub-bracket 402 is located at the top of the first battery mounting groove 501. The second sub-bracket 402, the first longitudinal beam 101, and the second longitudinal beam 102 together form the second battery mounting groove 502.

[0040] Specifically, the fourth support segment 4021 and the fifth support segment 4022 extend downward at an angle, and their lower ends gradually approach each other in the left and right directions. The sixth support segment 4023 connects the fourth support segment 4021 and the fifth support segment 4022. In this way, the fourth support segment 4021, the fifth support segment 4022, and the sixth support segment 4023 together form an inverted trapezoidal structure. The inclined fourth support segment 4021 and the fifth support segment 4022 can effectively distribute the load and improve the bending and torsional resistance of the second sub-support 402. The sixth support segment 4023 can fix the lower ends of the fourth support segment 4021 and the fifth support segment 4022, improving their stability. Moreover, the design that is wider at the top and narrower at the bottom facilitates the placement and installation of the battery 60.

[0041] Furthermore, the upper end of the fourth bracket segment 4021 is connected to the first longitudinal beam 101, the upper end of the fifth bracket segment 4022 is connected to the second longitudinal beam 102, and the sixth bracket segment 4023 extends in the left and right direction and connects between the lower ends of the fourth bracket segment 4021 and the fifth bracket segment 4022. In this way, the sixth bracket segment 4023 can provide support and fixation for the bottom of the battery 60. The fourth bracket segment 4021 and the fifth bracket segment 4022 can transfer the force on the sixth bracket segment 4023 to the longitudinal beam 10, thereby providing stable support for the battery 60 and improving the stability and reliability of the battery 60. Moreover, the second sub-bracket 402, the first longitudinal beam 101 and the second longitudinal beam 102 together form the second battery mounting groove 502. This not only provides installation space for the battery 60, but also provides good positioning and protection for the battery 60, preventing the battery 60 from shifting during the driving of the vehicle 1000, and also facilitates the installation and removal of the battery 60.

[0042] Furthermore, the second sub-bracket 402 is located above the first sub-bracket 401, which can form more than one battery mounting slot 50 in the vertical direction. This not only allows for the efficient arrangement of multiple batteries 60 in a limited space, increasing the total capacity of the batteries 60 in the vehicle 1000 and improving the range of the vehicle 1000, but also improves the space utilization and structural compactness of the vehicle 1000.

[0043] Furthermore, the upper ends of both the fourth bracket segment 4021 and the fifth bracket segment 4022 are provided with second connecting segments extending in the vertical direction. These second connecting segments have fixing holes, and the longitudinal beam 10 has mounting holes corresponding to the positions where the second sub-bracket 402 is connected. The fixing holes and mounting holes correspond in shape and size. Fasteners are sequentially inserted through the fixing holes and mounting holes to connect and fix the second sub-bracket 402 and the longitudinal beam 10. This not only makes the connection between the second sub-bracket 402 and the longitudinal beam 10 simple, direct, stable, and reliable, but also facilitates the installation and disassembly of the second sub-bracket 402, thereby facilitating the installation and disassembly of the battery 60 in the second battery mounting slot 502. The fixing holes and mounting holes can be threaded holes, and the fasteners can be screws.

[0044] In some embodiments of this utility model, the second sub-support 402 can be an integrally formed structural component, which can improve the overall structural strength and rigidity of the second sub-support 402, reduce the assembly gap between each support segment, avoid stress concentration caused by splicing between each support segment, and thus ensure the stability and safety of the second battery mounting slot 502 when bearing the weight of the battery 60.

[0045] Combination Figures 1-7 As shown, the battery mounting bracket 30 also includes a second battery mounting bracket 302. The second battery mounting bracket 302 is spaced apart on the front side of the first battery mounting bracket 301 and includes a third sub-bracket 403. The third sub-bracket 403 includes a seventh bracket segment 4031, an eighth bracket segment 4032, and a ninth bracket segment 4033. The seventh bracket segment 4031 and the eighth bracket segment 4032 extend downwards at an angle and gradually approach each other in the left and right directions. The ninth bracket segment 4033 is connected between the lower ends of the seventh bracket segment 4031 and the eighth bracket segment 4032. The upper ends of the seventh bracket segment 4031 and the eighth bracket segment 4032 are respectively connected to the first longitudinal beam 101 and the second longitudinal beam 102. The third sub-bracket 403, the first longitudinal beam 101, and the second longitudinal beam 102 together form the third battery mounting groove 503.

[0046] Specifically, the seventh bracket segment 4031 and the eighth bracket segment 4032 extend downward at an angle, and their lower ends gradually approach each other in the left and right directions. The ninth bracket segment 4033 connects the seventh bracket segment 4031 and the eighth bracket segment 4032. In this way, the seventh bracket segment 4031, the eighth bracket segment 4032 and the ninth bracket segment 4033 together form an inverted trapezoidal structure. The inclined seventh bracket segment 4031 and the eighth bracket segment 4032 can effectively distribute the load and improve the bending and torsional resistance of the third sub-bracket 403. The ninth bracket segment 4033 can improve the stability of the seventh bracket segment 4031 and the eighth bracket segment 4032. Moreover, the design of being wider at the top and narrower at the bottom can facilitate the installation of the battery 60.

[0047] Furthermore, the upper end of the seventh bracket segment 4031 is connected to the first longitudinal beam 101, the upper end of the eighth bracket segment 4032 is connected to the second longitudinal beam 102, and the ninth bracket segment 4033 extends in the left and right direction and connects between the lower ends of the seventh bracket segment 4031 and the eighth bracket segment 4032. In this way, the ninth bracket segment 4033 can provide support and fixation for the bottom of the battery 60. The seventh bracket segment 4031 and the eighth bracket segment 4032 can transfer the force on the ninth bracket segment 4033 to the longitudinal beam 10, thereby providing stable support for the battery 60 and improving the stability and reliability of the battery 60. Moreover, the third sub-bracket 403, the first longitudinal beam 101 and the second longitudinal beam 102 together form the third battery mounting groove 503. This not only provides installation space for the battery 60, but also provides good positioning and protection for the battery 60, preventing the battery 60 from shifting during the driving of the vehicle 1000, and also facilitates the installation and removal of the battery 60.

[0048] Furthermore, the upper ends of the seventh support segment 4031 and the eighth support segment 4032 are both provided with extension segments in the left and right directions. The upper side of each extension segment is provided with a third connecting segment. The third connecting segment has a right-angled triangular structure. The shorter right-angled side is connected to the extension segment at the upper end of the seventh support segment 4031 and the eighth support segment 4032, and the longer right-angled side is connected to the longitudinal beam 10, so as to make the connection between the third sub-support 403 and the longitudinal beam 10 more stable.

[0049] Furthermore, a fixing hole is provided on the third connecting section, and a mounting hole is provided on the longitudinal beam 10 corresponding to the position where the third sub-support 403 is connected. The fixing hole and the mounting hole also correspond in shape and size. Fasteners are sequentially inserted through the fixing hole and the mounting hole to connect and fix the third sub-support 403 and the longitudinal beam 10. This not only makes the connection between the third sub-support 403 and the longitudinal beam 10 simple, direct, stable and reliable, but also facilitates the installation and disassembly of the third sub-support 403, thereby facilitating the installation and disassembly of the battery 60 in the third battery mounting slot 503. The fixing hole and the mounting hole can be threaded holes, and the fastener can be a screw.

[0050] In some embodiments of this utility model, the third sub-support 403 can be an integrally formed structural component, which can improve the overall structural strength and rigidity of the third sub-support 403, reduce the assembly gap between each support segment, avoid stress concentration caused by splicing between each support segment, and thus ensure the stability and safety of the third battery mounting slot 503 when bearing the weight of the battery 60.

[0051] Combination Figures 1-7As shown, the second battery mounting bracket 302 includes a fourth sub-bracket 404, which is located above the third sub-bracket 403 and includes a tenth bracket segment 4041, an eleventh bracket segment 4042, and a twelfth bracket segment 4043. The tenth bracket segment 4041 and the eleventh bracket segment 4042 extend in the vertical direction and their lower ends are respectively connected to the first longitudinal beam 101 and the second longitudinal beam 102. The twelfth bracket segment 4043 is connected between the upper end of the tenth bracket segment 4041 and the upper end of the eleventh bracket segment 4042. The fourth sub-bracket 404, the third sub-bracket 403, the first longitudinal beam 101, and the second longitudinal beam 102 together form a fourth battery mounting groove 504.

The lower end of the tenth support segment 4041 is connected to the first longitudinal beam 101, and the lower end of the eleventh support segment 4042 is connected to the second longitudinal beam 102. The twelfth support segment 4043 extends horizontally and connects the upper ends of the tenth support segment 4041 and the eleventh support segment 4042. In this way, the twelfth support segment 4043 can provide a limiting and fixing function for the top of the battery 60, thereby providing stable support for the battery 60 and lifting the battery 60. To ensure stability and reliability, the tenth bracket segment 4041 and the eleventh bracket segment 4042 can transfer the force received by the twelfth bracket segment 4043 to the longitudinal beam 10. Moreover, the fourth sub-bracket 404, the third sub-bracket 403, the first longitudinal beam 101 and the second longitudinal beam 102 together enclose and form the first battery mounting groove 501. This not only provides installation space for the battery 60, but also provides good limiting and protection for the battery 60, preventing the battery 60 from shifting during the driving of the vehicle 1000. At the same time, it also facilitates the installation and removal of the battery 60.

[0053] Furthermore, the fourth sub-bracket 404 is located above the third sub-bracket 403, which allows more than one battery mounting slot 50 to be formed in the vertical direction corresponding to the fourth sub-bracket 404 and the third sub-bracket 403. This not only allows for the efficient arrangement of multiple batteries 60 within a limited space, increasing the total capacity of the batteries 60 in the vehicle 1000 and improving the range of the vehicle 1000, but also improves the space utilization and structural compactness within the vehicle 1000.

[0054] Furthermore, fixing holes are provided on the tenth bracket segment 4041 and the eleventh bracket segment 4042, and mounting holes are provided on the longitudinal beam 10 at the positions corresponding to the connection of the fourth sub-bracket 404. The fixing holes and mounting holes also correspond in shape and size. Fasteners are sequentially inserted through the fixing holes and mounting holes to connect and fix the fourth sub-bracket 404 and the longitudinal beam 10. This not only makes the connection between the fourth sub-bracket 404 and the longitudinal beam 10 simple, direct, stable and reliable, but also facilitates the installation and disassembly of the fourth sub-bracket 404, thereby facilitating the installation and disassembly of the battery 60 in the fourth battery mounting slot 504. The fixing holes and mounting holes can be threaded holes, and the fasteners can be screws.

[0055] In some embodiments of this utility model, both the tenth support segment 4041 and the eleventh support segment 4042 include two structural segments extending in the vertical direction. One structural segment is arranged parallel to the longitudinal beam 10, and the other is arranged perpendicular to the longitudinal beam 10, forming two mutually perpendicular structural segments. This creates a triangular space between the two structural segments, which can improve the structural strength and load-bearing capacity of the fourth sub-support 404 and prevent the fourth sub-support 404 from deforming or breaking. In addition, the structural segment arranged parallel to the longitudinal beam 10 is provided with fixing holes for installing the fourth sub-support 404.

[0056] In some embodiments of this utility model, the fourth sub-support 404 can be an integrally formed structural component, which can improve the overall structural strength and rigidity of the fourth sub-support 404, reduce the assembly gap between each support segment, avoid stress concentration caused by splicing between each support segment, and thus ensure the stability and safety of the fourth battery mounting slot 504 when bearing the weight of the battery 60.

[0057] In some embodiments of this utility model, the specific dimensions of the battery mounting bracket 30 in each direction can be adjusted according to specific needs and the specific structure of the vehicle 1000.

[0058] Combination Figure 1 , Figure 2 and Figure 7As shown, the first battery mounting slot 501 protrudes downward relative to the longitudinal beam 10, and the bottom of the third battery mounting slot 503 is higher than the bottom of the first battery mounting slot 501 to avoid obstructing the front axle of the vehicle 1000. Specifically, the first battery mounting slot 501 protrudes downward relative to the longitudinal beam 10, and the bottom of the third battery mounting slot 503 is higher than the bottom of the first battery mounting slot 501. This not only prevents structural interference between the front axle of the vehicle 1000 and the battery 60 and the third sub-bracket 403 in the third battery mounting slot 503, thus preventing difficulty in installing the battery 60 in the third battery mounting slot 503, but also leaves a certain gap between the front axle of the vehicle 1000 and the third battery mounting slot 503, preventing the front axle from moving upward and hitting the battery 60 in the third battery mounting slot 503, thereby improving the stability of the battery 60. In addition, it can make full use of the vertical space to efficiently arrange multiple batteries 60 in a limited space, thereby increasing the total capacity of the batteries 60 in the vehicle 1000 and improving the space utilization and structural compactness of the vehicle 1000.

[0059] Combination Figure 1 , Figure 2 and Figure 7 As shown, the top of the second battery mounting slot 502 is lower than the upper side of the longitudinal beam 10, and the bottom of the fourth battery mounting slot 504 is located on the upper side of the longitudinal beam 10. Specifically, this not only allows the top of the fourth battery mounting slot 504 to be higher than the top of the second battery mounting slot 502, corresponding to the design where the bottom of the third battery mounting slot 503 is higher than the bottom of the first battery mounting slot 501, ensuring the structural rationality and reliability of the vehicle 1000, but also prevents structural interference between the battery 60 and the second sub-bracket 402 in the second battery mounting slot 502 and the components above them, thus avoiding difficulties in installing the battery 60 in the second battery mounting slot 502. In addition, it can make full use of the space in the vertical direction to efficiently arrange multiple batteries 60 in a limited space, thereby increasing the total capacity of the batteries 60 in the vehicle 1000 and improving the space utilization and structural compactness of the vehicle 1000.

[0060] The vehicle 1000 according to this utility model mainly includes the aforementioned frame 100. Specifically, because the frame 100 has a more compact and reliable structure, it ensures that the battery 60 has sufficient space and reduces the wheelbase of the vehicle 1000. Applying the frame 100 to the vehicle 1000 not only increases the total capacity of the battery 60 within the vehicle 1000 and improves the vehicle 1000's range, but also enhances the vehicle 1000's maneuverability.
