[0029] Please refer to together Figures 1 to 4, the new energy power chassis provided by the present utility model will be described hereinafter. The new energy power chassis includes a drive axle 1, a vehicle frame 2 connected to the drive axle 1, and an electric driving component 3, a battery module 4, a suspension system 5, a braking system 6, and a control system 7 provided on the vehicle frame 2; wherein, the suspension system 5 is connected between the drive axle 1 and the vehicle frame 2, and the braking system 6 acts on the wheel discs at both ends of the drive axle 1; the electric driving component 3 is integrally installed on the drive axle 1 and the output end is in transmission connection with the drive axle 1; the battery module 4 includes at least one group of high-voltage power battery packs 401 provided on the front side of the drive axle 1 and a low-voltage control power supply 402 provided on the rear side of the drive axle 1; the control system 7 includes a high-voltage distribution box 701 and a low-voltage distribution box 702, the high-voltage distribution box 701 is provided between the electric driving component 3 and the high-voltage power battery pack 401 and is electrically connected to both respectively, and the low-voltage distribution box 702 is provided between the electric driving component 3 and the low-voltage control power supply 402 and is electrically connected to both respectively.

[0030] It should be noted that in this embodiment, the vehicle frame 2 is welded from high-strength steel, which is beneficial to reducing weight on the basis of ensuring structural strength and promoting the achievement of lightweight indicators; specifically, the vehicle frame 2 uses two channel steels or I-beams (which can be profiles or high-strength steel plates stamped and bent) as longitudinal beams 201, and reinforcing rib plates are arranged at intervals in the notch of the channel steel to enhance strength.

[0031] In this embodiment, the electric driving component 3 is integrally arranged on the drive axle 1.

The control system 7 includes a motor controller 705 for controlling the speed and torque of the drive motor, and an automatic control unit 706 for controlling the multi-speed reducer to shift gears; wherein, the motor controller 705 is connected through a controller mounting bracket 7051 welded to the vehicle frame 2, and the automatic control unit 706 is connected to the longitudinal beam 201 of the vehicle frame 2 through fasteners such as bolts, thereby improving the layout compactness of the power part, and installing the control units with different functions as separate modules can not only reduce the overall installation space occupied by the control system 7, but also facilitate the maintenance of corresponding module failures.

[0032] In this embodiment, the suspension system can be an air spring suspension using the prior art or a shock absorber suspension using the prior art. Of course, considering the driving stability and comfort of the vehicle, the suspension system can preferably adopt a combined structure of an air spring and a shock absorber.

[0033] In this embodiment, the braking system 6 can be a TEBS (Electronically Controlled Brake System) braking system commonly used in trailers, which can optimize the distribution of braking force, improve the braking coordination between the tractor and the trailer, and thus ensure a short braking response time.

[0034] In this embodiment, the high-voltage power battery pack 401 adopts battery modules with high energy density, and each battery module can be individually configured with a cooling system to ensure the stable and safe operation of the high-voltage power battery pack 401; considering safety performance, the above-mentioned high-voltage power battery pack 401 can be installed between the two longitudinal beams 201, using the longitudinal beams 201 to form collision protection and making full use of the space between the two longitudinal beams 201 to improve the compactness of the installation layout.

[0035] In this embodiment, the low-voltage control power supply 402 is formed by connecting two twelve-volt batteries in series to form a twenty-four-volt low-voltage DC power supply, aiming to supply power to the vehicle's low-voltage wiring harness. At the same time, a main power switch 204 can be set on the outer side wall of the longitudinal beam 201, which is a convenient operation position on the frame 2, so as to realize the on-off control of the low-voltage control power supply 402.

[0036] Compared with the prior art, the new energy power chassis provided in this embodiment integrally installs an electric driving component 3 on the drive axle 1, and a high-voltage power battery pack 401 is arranged on the front side of the drive axle 1 to supply power to the electric driving component 3. The overall structure layout is compact. It can not only provide driving power through the electric driving component 3, but also utilize the kinetic energy recovery of the electric driving component 3 to achieve auxiliary braking, thereby improving the climbing ability, acceleration and braking performance of the trailer, and improving the stability of power output; at the same time, the low-voltage control power supply 402 is arranged on the rear side of the drive axle 1, and the low-voltage distribution box 702 is connected to the frame 2 close to the low-voltage control power supply 402, and the high-voltage distribution box 701 is connected to the frame 2 close to the high-voltage power battery pack 401. This can not only shorten the wiring path, but also separate the high-voltage and low-voltage circuits, thus facilitating circuit maintenance and reducing the risk of circuit failures, and improving stability.

[0037] In some embodiments, refer to Figures 1 to 3 , a front support bridge 8 and a rear support bridge 9 that support under the frame 2 are respectively arranged on the front and rear sides of the drive axle 1. Both the front support bridge 8 and the rear support bridge 9 are connected to the frame 2 through a suspension system 5, and the braking system 6 has a braking force output end acting on the two end discs of the front support bridge 8 and the two end discs of the rear support bridge 9; wherein, the control system 7 includes a braking force distribution control module 703, and the braking force distribution control module 703 is connected to the frame 2 and electrically connected to the low-voltage distribution box 702.

[0038] The middle drive axle 1 and the front support axle 8 and the rear support axle 9 on both sides of the front and rear of the drive axle 1 form a three-axle chassis. The middle axle is used as the drive axle 1 to output power and provide support force to the vehicle frame 2 through the front and rear axles, thus ensuring the driving stability and load-bearing capacity of the trailer; on this basis, the suspension system 5 takes into account the connection between the front support axle 8 and the rear support axle 9 and the vehicle frame 2 to ensure driving stability and comfort, and the braking system 6 distributes to the brake discs (for installing tires) on the drive axle 1, the front support axle 8, and the rear support axle 9 through its braking force distribution control module 703 (specifically, it can be a TEBS electronic braking module), thereby improving the braking effect.

[0039] As a specific implementation manner of the above braking system 6, please refer to Figure 1 and Figure 3 , the braking system 6 includes a plurality of brakes 601, a brake pump, a plurality of air storage tanks 602, and a parking brake valve; each brake 601 is respectively connected to the brake discs at both ends of the drive axle 1, the brake discs at both ends of the front support axle 8, and the brake discs at both ends of the rear support axle 9; the brake pump is connected to the vehicle frame 2 and connected to each brake 601; each air storage tank 602 is connected to the front support axle 8 and / or the rear support axle 9, and each air storage tank 602 is connected to the brake pump; the parking brake valve is connected to the vehicle frame 2 and connected to each brake 601; wherein, the braking force distribution control module 703 is connected between the brake pump and each brake 601, and is used to control the gas pumped to each brake 601 to distribute the braking force acting on each brake disc, and is also used to control the parking brake valve.

[0040] Here, the brake 601 can adopt a pneumatic disc brake 601. The vehicle frame 2 is provided with a strengthening cross beam above the front support axle 8 and the rear support axle 9. On the one hand, it improves the structural strength of the vehicle frame 2. On the other hand, an air storage tank 602 can be installed on each of the two strengthening cross beams and high-pressure air is output to each brake 601 through the brake pump to achieve braking, which can improve the braking response speed; specifically, the brake pump is connected to the air inlet hole of the braking force distribution control module 703 to input high-pressure air. Some of the air outlet holes of the braking force distribution control module 703 are respectively connected to each brake 601 to distribute high-pressure air to each brake 601 to achieve braking force distribution. At the same time, the braking force distribution control module 703 also has several air outlet holes respectively connected to the parking brake valve, thereby providing high-pressure air to the parking brake valve to achieve parking braking, so that the chassis has both service braking and parking braking functions.

[0041] It should be noted that the above suspension system 5 includes shock absorbers and air suspensions. The shock absorbers and air suspensions are both connected to the vehicle frame 2, and the air suspension is connected to at least one air storage tank 602. Since a combined structure of shock absorbers and air suspensions is adopted between the drive axle 1, the front support axle 8 and the rear support axle 9 and the vehicle frame 2, the air suspension of the front support axle 8 can be connected to the air storage tank 602 on the strengthening cross beam above it, the air suspension of the rear support axle 9 can be connected to the air storage tank 602 on the strengthening cross beam above it, and the air suspension of the drive axle 1 can be connected to any one of the air storage tanks 602. This can ensure the compactness of the overall structural layout and at the same time ensure the air pressure stability of the air suspension.

[0042] Specifically, as Figure 3 and Figure 4 shown, in this embodiment, the vehicle frame 2 includes two longitudinals 201 arranged parallel and opposite to each other. The electric driving member 3 and the battery module 4 are both located between the two longitudinals 201. The high-voltage power distribution box 701 and the low-voltage distribution box 702 are both fixedly connected to the inner side of one of the longitudinals 201. On the basis of using the two longitudinals 201 as the foundation of the chassis load-bearing structure, it can also provide installation positions and spaces for the battery module 4, the high-voltage power distribution box 701 and the low-voltage distribution box 702, improve the structural compactness, and at the same time can use the two longitudinals 201 to form collision protection for the space between them, thereby reducing the risk of the battery module 4, the high-voltage power distribution box 701 and the low-voltage distribution box 702 being impacted and improving the safety of the power system.

[0043] It should be noted that referring to Figure 2 , in this embodiment, the control system 7 includes a DCDC converter 704. The DCDC converter 704 is connected to the inner side of one of the longitudinals 201 and is located on the side of the high-voltage power distribution box 701. The high-voltage power distribution box 701 and the low-voltage distribution box 702 are electrically connected through the DCDC converter 704. By setting the DCDC converter 704, the high-voltage power battery pack 401 can charge the low-voltage control power supply 402, thereby avoiding the low-voltage control power supply 402 running out of power and affecting the working stability of the control system 7.

[0044] Specifically, the connection method of the above high-voltage power battery pack 401 on the vehicle frame 2 is as Figure 3 shown. A suspension bracket 202 is fixedly connected between the two longitudinals 201, and the high-voltage power battery pack 401 is arranged on the suspension bracket 202. Here, the suspension bracket 202 is welded by high-strength steel. By using the suspension bracket 202, the high-voltage power battery pack 401 can be suspended and installed between the two longitudinals 201, thereby improving the structural compactness.

[0045] In some embodiments, please refer to Figures 1 to 3, the new energy power chassis further includes a thermal management integration module 10. The thermal management integration module 10 is connected to the vehicle frame 2 through a bracket 101 and is located on the front side of the high-voltage power battery pack 401. The thermal management integration module 10 is used to cool the high-voltage power battery pack 401 and the electric drive components 3. Specifically, the thermal management integration module 10 can cool the high-voltage power battery pack 401 by circulating coolant into the liquid cooling systems separately configured for each battery module of the high-voltage power battery pack 401. At the same time, the electric drive components 3 can also be cooled by water cooling. Specifically, a cooling fan 102 is integrally arranged on the thermal management integration module 10 and is connected between the two longitudinal beams 201 of the vehicle frame 2 through the bracket 101. And a water pump 103 for enabling the thermal management integration module 10 to supply coolant to the high-voltage power battery pack 401 and the electric drive is connected to the vehicle frame 2 through a pump bracket. Of course, a coolant tank 104 for containing coolant is also connected to the vehicle frame 2. The coolant tank 104 is connected to the water pump 103 to provide coolant. The overall structure is simple and compact.

[0046] It should be noted that for the convenience of quickly charging the high-voltage power battery pack 401, refer to Figure 4 , a DC fast charging socket 203 is provided on the vehicle frame 2. The DC fast charging socket 203 is electrically connected to the high-voltage power distribution box 701.

[0047] Based on the same inventive concept, in combination with Figures 1 to 4 understanding, the embodiment of the present application further provides a new energy trailer, including the above new energy power chassis.

[0048] Compared with the prior art, the new energy trailer provided in this embodiment adopts the above new energy power chassis. By integrally installing the electric drive components 3 on the drive axle 1 and arranging the high-voltage power battery pack 401 on the front side of the drive axle 1 to supply power to the electric drive components 3, the overall structural layout is compact. It can not only provide driving power through the electric drive components 3, but also utilize the kinetic energy recovery of the electric drive components 3 to achieve auxiliary braking, thereby improving the climbing ability, acceleration and braking performance of the trailer, and thus improving the stability of power output. At the same time, the low-voltage control power supply 402 is arranged on the rear side of the drive axle 1, and the low-voltage power distribution box 702 is connected to the vehicle frame 2 close to the low-voltage control power supply 402, and the high-voltage power distribution box 701 is connected to the vehicle frame 2 close to the high-voltage power battery pack 401.
