[0026] The technical solution is explained below. In existing chassis, the motor is integrated with the rear axle assembly via a reducer. The motor is the primary heat source, and this tight integration with the rear axle can lead to heat buildup, causing oil leaks in the rear axle assembly, affecting its lifespan and reliability. Furthermore, this high integration means that a single component failure may necessitate replacing the entire assembly, increasing maintenance complexity and cost. Therefore, if… Figure 1 and Figure 2 As shown, this utility model provides a dedicated chassis for unmanned new energy vehicles, comprising: Frame 1, At least two axle assemblies 2 are spaced apart at both ends of the frame 1 along the length of the frame 1; An electric drive assembly 3 is mounted on the frame 1, located between at least two axle assemblies 2, and spaced apart from the axle assemblies 2. The electric drive assembly 3 has a transmission part that is connected to one axle assembly 2 along the length of the frame 1 for outputting power. Cooling component 4, mounted on the frame 1, is used to cool electric drive component 3.

[0027] The electric drive assembly 3 is separately mounted on the frame 1, located between the two axle assemblies 2, and spaced apart from them. The electric drive assembly 3 is connected to the axle assembly 2 via a transmission unit, outputting torque to the axle assembly 2 to achieve the movement of the frame 1. In this way, the heat of the electric drive assembly 3 will not be transferred to the axle assembly 2, and both the electric drive assembly 3 and the axle assembly 2 can be inspected and maintained independently.

[0028] like Figure 1 As shown, at least two axle components 2 are configured as follows: The front axle component 21 is disposed at the front end of the frame 1 along the direction of movement of the frame 1; The rear axle component 22 is located at the rear end of the frame 1 and is connected to the transmission part of the electric drive assembly 3.

[0029] The electric drive assembly 3 is connected to the rear axle assembly 22 via the transmission unit, which can better provide the vehicle with traction and climbing performance, and is more conducive to transporting heavy objects.

[0030] like Figure 1 and Figure 2 As shown, the electric drive assembly 3 includes: Motor 31 is mounted on frame 1; The drive shaft 32 is arranged along the length of the frame 1. One end of the drive shaft 32 is connected to the output end of the motor 31, and the other end is connected to the axle assembly 2. The drive shaft 32 serves as a transmission part. The electronic control component 33 is mounted on the frame 1 and electrically connected to the motor 31, and is used to regulate the operating current input to the motor 31.

[0031] Specifically, the frame 1 includes two crossbeams 11 and several longitudinal beams 12. The two crossbeams 11 extend laterally and are arranged in parallel. The several longitudinal beams 12 are arranged at intervals between the opposite faces of the two crossbeams 11. The motor 31 is arranged between the two crossbeams 11, and the output shaft of the motor 31 faces the rear axle component 22. The drive shaft 32 is used to transmit the torque output by the motor 31 to the rear axle component 22.

[0032] like Figure 1 and Figure 2 As shown, in order to ensure effective heat dissipation of the electric drive assembly 3, the cooling assembly 4 has a cooling circuit, which is connected in sequence to the motor 31 and the electronic control component 33, and is used to cool the motor 31 and the electronic control component 33 in sequence. Specifically, the electronic control component 33 is mounted on one of the crossbeams 11 of the frame 1 and is located on the side of the crossbeam 11 away from the other crossbeam. That is, the electronic control component 33 and the motor 31 are spaced apart by a crossbeam 11, so that the heat between the two will not be transferred to each other and the heat generated by the two can be carried away by the surrounding air.

[0033] Under the action of the cooling component 4, the electronic control component 33 and the motor 31 can be cooled down in sequence to ensure that the electronic control component 33 and the motor 31 work normally.

[0034] like Figure 2 As shown, in order to effectively reduce the temperature of the motor 31 and the electronic control components 33, the cooling assembly 4 includes: Radiator 41 is mounted on the frame 1; Cooling pipe 42 is connected in sequence to radiator 41, electrical control component 33 and motor 31; A circulation pump 43 is mounted on the frame 1 and connected to the cooling pipe 42 to form a cooling circuit, which is used to circulate the coolant within the cooling circuit.

[0035] Cooling pipe 42 connects components such as electrical control component 33, motor 31 and radiator 41 to form a closed circulation channel; circulation pump 43 provides power for the movement of coolant, so that it circulates continuously in the cooling circuit; radiator 41 releases the heat of coolant into the air through a core containing cooling pipes and fins.

[0036] like Figure 1 and Figure 2 As shown, in order to ensure good heat dissipation of the radiator 41, the radiator 41 is located at the front end of the frame 1 along the direction of movement of the frame 1.

[0037] Specifically, when the vehicle is in motion, air enters from the front grille and directly into the radiator 41. The moving air rushes into the radiator 41, carrying away a large amount of heat without additional energy consumption. When the vehicle is stationary or at low speed, the fan equipped on the radiator 41 is activated to supplement the cooling demand.

[0038] like Figure 3 As shown, the battery pack 5 is a battery swapping structure. The battery pack 5 is detachably mounted on the frame 1 and electrically connected to the cooling assembly 4 and the electric drive assembly 3 to provide current.

[0039] The charging rate of batteries in new energy vehicles is slower than that of gasoline vehicles. Battery module 5 achieves rapid energy replenishment through a battery swapping structure, enabling the vehicle to continue operating.

[0040] like Figure 4 and Figure 5 As shown, battery assembly 5 includes: The battery swapping socket 51 is fixedly mounted on the vehicle frame 1 and electrically connected to the electronic control component 33; The battery compartment 52 is mounted on the battery swapping base 51 and is electrically connected to the battery swapping base 51. At least two locking components 53 are provided on the battery swapping base 51 for locking or unlocking the battery compartment 52.

[0041] The battery compartment 52 can be locked or released relative to the battery swapping seat 51, thus achieving the purpose of battery swapping in the battery compartment 52 and enabling the vehicle to operate continuously.

[0042] Specifically, each locking component 53 includes a linear drive unit 531 and a locking block 532. The linear drive unit 531 is disposed on the battery swapping seat 51 along the width direction of the frame 1, and the locking block 532 is also slidably disposed on the battery swapping seat 51 along the width direction of the frame 1. The locking block 532 is hinged to the output end of the linear drive unit 531. Under the action of the linear drive unit 531, the locking block 532 can move along the width direction of the battery swapping seat 51 to lock or release the battery compartment 52 along the width direction of the battery swapping seat 51.

[0043] Specifically, there are four locking components 53 arranged in an array on the battery swapping base 51. The linear drive unit 531 is configured as a cylinder, and the locking blocks 532 are slidably mounted on the battery swapping base 531 via guide rails. Two locking components 53 located on the same side of the battery swapping base 51 cooperate with each other. The battery compartment 52 is provided with four positioning slots 5201. When the battery compartment 52 is located on the battery swapping base 51, under the action of the four locking components 53, the group of locking blocks 532 move closer to each other, locking the battery compartment 52 onto the battery swapping base 51, thereby realizing the locking and unlocking of the battery compartment 52.

[0044] like Figure 5 As shown, in order to pre-position the battery compartment 52 relative to the battery swapping base 51, the battery assembly 5 also includes: Positioning component 54 is installed on battery swapping base 51 and is used to pre-position battery compartment 52.

[0045] The positioning component 54 is configured as a conical positioning rod. Correspondingly, a positioning hole adapted to the positioning rod is provided on the side of the battery compartment 52 near the battery swapping base 51 to ensure the stability of the battery compartment 52 on the battery swapping base 51.

[0046] The working principle of this unmanned new energy special chassis is to set the electric drive component 3 separately on the frame 1, and the motor 31 and the electronic control component 33 in the electric drive component 3 are set separately on the frame 1 along the width direction of the frame 1, so that the motor 31 and the electronic control component 33 can achieve good heat dissipation. In addition, a cooling component 4 is also configured to dissipate heat from the motor 31 and the electronic control component 33, ensuring that heat is not transferred and accumulated between the two.

[0047] On the other hand, this utility model also provides an unmanned new energy vehicle, including a car, which is equipped with the aforementioned unmanned new energy special chassis.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
