[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0028] In the present disclosure, unless otherwise stated, the directions or positional relationships indicated by directional words such as "up" and "down" are defined based on the up and down positions of the battery-swapping tractor in normal driving conditions. They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, they cannot be understood as limitations on the present disclosure. The terms "first", "second", "third", etc. are used to distinguish different components and do not have sequentiality or importance.

[0029] like Figure 1-Figure 5 As shown, the present disclosure provides a motor and battery-swap box fixing bracket, including a bracket body 1, on which a battery-swap box fixing portion 2, a longitudinal beam fixing portion 3 and a motor fixing portion 4 are arranged, and the battery-swap box fixing portion 2, the longitudinal beam fixing portion 3 and the motor fixing portion 4 are arranged at intervals in the up and down directions, the battery-swap box fixing portion 2 is located above the longitudinal beam fixing portion 3, and the motor fixing portion 4 is located below the longitudinal beam fixing portion 3, the longitudinal beam fixing portion 3 is used to be detachably connected to the longitudinal beam 5 of the battery-swap tractor located between the battery-swap box 6 and the motor 7, the battery-swap box fixing portion 2 is used to be detachably connected to the mounting base 8 of the battery-swap box 6, and the motor fixing portion 4 is used to be detachably connected to the mounting bracket 9 of the motor 7.

[0030] Through the above technical solution, the battery-swap box fixing part 2, the longitudinal beam fixing part 3 and the motor fixing part 4 are all integrated on the bracket body 1, and the battery-swap box 6 and the motor 7 can be connected to the longitudinal beam 5 at the same time through the bracket body 1, thereby solving the problem of interference and inconvenience in installation caused by using the battery-swap box fixing bracket and the motor fixing bracket separately. In addition, integrating the battery-swap box fixing part 2, the longitudinal beam fixing part 3 and the motor fixing part 4 on the bracket body 1 can also increase the installation space of the bracket body 1 on the longitudinal beam 5.

[0031] Here, combined Figure 1 and Figure 2 , the battery-swap box fixing part 2 is connected to the side of the mounting base 8 of the battery-swap box 6 in the horizontal direction, and the mounting base 8 of the battery-swap box 6 is installed above the longitudinal beam 5, that is, the longitudinal beam 5 bears the gravity of the battery-swap box 6, and the battery-swap box fixing part 2 limits the base 8 of the battery-swap box 6 in the horizontal direction. The bracket body 1 will not bear the gravity of the battery-swap box 6, but only the gravity of the motor 7. In some embodiments, the bracket body 1 can be a steel plate or a galvanized plate, and the yield strength of the bracket body 1 can be 340Mpa-500Mpa, and the thickness can be 8mm-10mm.

[0032] In the present disclosure, the up-down direction may be a vertical direction. Optionally, the bracket body 1 extends in a straight line along the up-down direction. In this way, the extension direction of the bracket body 1 may be parallel to the gravity direction of the motor 7, thereby avoiding the situation where the extension direction of the bracket body 1 is not parallel to the gravity direction of the motor 7 and torque is generated, so as to ensure the stability of the force applied to the bracket body 1.

[0033] Optionally, combined Figure 1 and Figure 2, the battery-swap box fixing part 2 includes a plurality of battery-swap box fixing holes 201, each of which is used for the first bolt 10 connected to the mounting base 8 of the battery-swap box 6 to pass through, so that the battery-swap box fixing part 2 is detachably connected to the mounting base 8 of the battery-swap box 6. The longitudinal beam fixing part 3 includes a plurality of longitudinal beam fixing holes 301, each of which is used for the second bolt 11 connected to the longitudinal beam 5 to pass through, so that the longitudinal beam fixing part 3 is detachably connected to the longitudinal beam 5. The motor fixing part 4 includes a plurality of motor fixing holes 401, each of which is used for the third bolt 12 connected to the mounting bracket 9 of the motor 7 to pass through, so that the motor fixing part 4 is detachably connected to the mounting bracket 9 of the motor 7. As an exemplary embodiment, the diameter of each battery-swap box fixing hole 201, each longitudinal beam fixing hole 301, and each motor fixing hole 401 can be 14mm-16mm.

[0034] Optionally, multiple battery-swap box fixing holes 201, multiple longitudinal beam fixing holes 301, and multiple motor fixing holes 401 are arranged in an array on the bracket body 1, so that multiple battery-swap box fixing holes 201, multiple longitudinal beam fixing holes 301, and multiple motor fixing holes 401 are evenly distributed on the bracket body 1, so as to improve the connection stability between the bracket body 1 and the mounting base 8 of the battery-swap box 6, the longitudinal beam 5, and the mounting bracket 9 of the motor 7. In some embodiments, such as Figure 4 As shown, the number of the battery swap box fixing holes 201 can be four, and they are distributed on the bracket body 1 in a 2*2 array; the number of the longitudinal beam fixing holes 301 can be nine, and they are distributed on the bracket body 1 in a 3*3 array; the number of the motor fixing holes 401 can be four, and they are distributed on the bracket body 1 in a 2*2 array.

[0035] Since the height of the rear axle of the battery-swapping tractor is lower than the height of the motor 7 in the vertical direction, in order to facilitate the output shaft of the motor 7 fixed on the mounting bracket 9 of the motor 7 to output torque to the rear axle, the motor fixing portion 4 optionally includes a plurality of fixing hole groups spaced apart in the vertical direction, each fixing hole group includes at least two motor fixing holes 401, and the connecting line of the motor fixing holes 401 in each fixing hole group extends obliquely downward, so that the output shaft of the motor 7 fixed on the mounting bracket 9 of the motor 7 also extends obliquely downward, so as to facilitate the transmission connection between the output shaft of the motor 7 and the transmission shaft of the rear axle. In some embodiments, such as Figure 4 As shown, two fixing hole groups may be provided along the up-down direction, and each fixing hole group includes two motor fixing holes 401 .

[0036] In order to improve the support strength of the bracket body 1, optionally, the cross section of the bracket body 1 is U-shaped. That is, the two ends of the bracket body 1 along the horizontal direction are bent to form flanges. In some embodiments, the width of the flange formed by bending can be 28mm-32mm.

[0037] In the related art, since the width of the battery swap box is relatively wide, in addition to providing support force to the battery swap box through the mounting base of the battery swap box, it is also necessary to connect multiple support rods to the longitudinal beam to provide support to the part of the battery swap box extending out of the longitudinal beam. In order to avoid interference with these support rods, optionally, the bracket body 1 includes a first part 101 and a second part 102 located below the first part 101, the battery swap box fixing part 2 is arranged on the first part 101, and the longitudinal beam fixing part 3 and the motor fixing part 4 are both arranged on the second part 102. The size of the first part 101 in the horizontal direction is smaller than the size of the second part 102 in the horizontal direction, so that an avoidance gap 13 can be formed between the first part 101 and the second part 102. By providing the avoidance gap 13, the above-mentioned support rod can be extended from the avoidance gap 13, thereby avoiding interference between the bracket body 1 and the support rod.

[0038] Optionally, the bracket body 1 further includes a support plate 14, which extends in the horizontal direction and is connected to the upper end of the second part 102, and the lower end of the first part 101 is supported on and connected to the support plate 14. The support of the first part 101 by the support plate 14 increases the strength of the first part 101, thereby reducing the impact caused by the reduction of the size of the first part 101 in the horizontal direction.

[0039] In order to reduce the weight of the support body 1 and reduce the load-bearing capacity of the longitudinal beam 5, the support body 1 is optionally provided with a plurality of weight-reducing holes 15, and the plurality of weight-reducing holes 15 are arranged at intervals in the vertical direction. Figure 4 As shown, the weight-reducing holes 15 may be elliptical or rectangular, and four holes may be provided on the bracket body 1 along the up-down direction.

[0040] According to the second aspect of the present disclosure, a battery-swapping tractor is provided, which includes a frame, a battery-swapping box 6, a motor 7, and the above-mentioned motor and battery-swapping box fixing bracket, the frame includes a longitudinal beam 5 located between the battery-swapping box 6 and the motor 7, the longitudinal beam fixing portion 3 of the motor and battery-swapping box fixing bracket is detachably connected to the longitudinal beam 5, the battery-swapping box fixing portion 2 of the motor and battery-swapping box fixing bracket is detachably connected to the mounting base 8 of the battery-swapping box 6, and the motor fixing portion 4 of the motor and battery-swapping box fixing bracket is detachably connected to the mounting bracket 9 of the motor 7. The battery-swapping tractor has all the technical effects of the above-mentioned motor and battery-swapping box fixing bracket, which will not be described in detail in the present disclosure.

[0041] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
