Abstract
Description
Technical Field
[0001] The present invention relates to the field of pure electric tractor vehicle structures, and in particular to a pure electric tractor chassis arrangement structure. In addition, the present invention also relates to a vehicle having the pure electric tractor chassis arrangement structure. Background Art
[0002] The development of new energy heavy-duty trucks has gradually shifted from policy-driven to technology-driven. Major traditional OEMs and new car manufacturers have increased their R&D investment to improve the performance of new energy heavy-duty trucks. Among them, reasonable layout has a crucial impact on the performance and reliability of the entire vehicle.
[0003] At present, the overall layout of the new energy heavy-duty truck chassis adopts the "oil-to-electric" chassis. The "oil-to-electric" chassis will not change the vehicle chassis structure as a whole, but adopts a "pin-in-the-slot" layout method. This layout method makes the space scattered and messy, with low utilization rate, and the battery pack is arranged in a "pin-in-the-slot" manner. In addition, the traditional systems such as suspension and braking are adapted and matched, resulting in poor overall coordination and great impact on comfort. In addition, due to the limitations of the chassis layout of fuel vehicles, in the absence of a system layout, there is a problem of "one vehicle, one state", and the layout modularization is low, resulting in poor versatility. Furthermore, fuel vehicles have no high-voltage wires. Harnesses, and relatively few low-voltage wiring harnesses and water pipes, and the wiring is "squeezed into every available space", resulting in messy wiring and poor safety. Furthermore, compared with fuel vehicles, electric vehicles have more and smaller electric accessories, and the "squeezed into every available space" layout leads to poor vehicle assembly and maintenance technology. Furthermore, most of the "oil-to-electric" models currently use "back-type" batteries. Due to the weight and size restrictions of the vehicle, the power is generally 282kWh, 350kWh and 400kWh, and the cruising range is limited. In addition, the "oil-to-electric" models are based on the adaptability improvement and modification of fuel vehicles, with a focus on verification and testing of electrical-related systems, and have relatively low safety.

Specifically, as Figure 1 As shown, the cabin module 200 is arranged at one end of the load-bearing frame 100 close to the front of the vehicle, the energy storage module 300 is arranged in the middle of the load-bearing frame 100 and is adjacent to the cabin module 200 and distributed along the length direction of the load-bearing frame 100, and the drive module 400 is arranged at one end of the rear end of the load-bearing frame 100.
[0022] See also Figure 4The energy storage module 300 is mainly used to arrange power batteries, and includes at least two battery systems 301 arranged side by side in the same length direction as the load-bearing frame 100, and a corresponding protection platform 306 is arranged above each battery system 301. The protection platform 306 can be arranged as follows Figure 4 The grid structure shown in can also be set to other structures that can protect the battery system 301. Of course, an integral protection platform 306 can also be set on all battery systems 301, instead of setting it up separately for each battery system 301, and the mutual structure between the protection platform 306 and the battery system 301 is not specifically limited. In order to enable the staff to conveniently perform maintenance and inspection operations on the components on the chassis, it is preferred that the protection platform 306 is set to a structure with a certain strength, capable of carrying an adult and hardly deformed, such as a steel grid structure. In addition, the protection platform 306 can also be set to a structure that can rotate relative to the load-bearing frame 100, so that when the battery system 301 needs to be inspected or replaced, it can facilitate the disassembly and assembly of the battery.
[0023] In addition, in one embodiment of the present application, three battery systems 301 are provided. Figure 4 As shown, the length direction of each battery system 301 is consistent with the length direction of the longitudinal beam, and the length directions of the three battery systems 301 are consistent and arranged side by side. The three battery systems 301 can be solidified as a whole and placed in the energy storage module 300, or they can be placed separately and side by side in the energy storage module 300, which is not specifically limited here. In this application, the energy storage module 300 is basically fully arranged with power batteries, so the power batteries can be arranged side by side as described above, so that the center of gravity of the whole vehicle is low and the degree of modularization is high, thereby optimizing the turning radius, making the driving smoothness high, and under the premise of meeting the passability of the whole vehicle, the wheelbase is the shortest, and the entire energy storage module 300 is fully arranged with batteries to maximize the power and improve the cruising range. In addition, based on different cruising range requirements, the energy storage module 300 can choose 400kWh, 513kWh, 600kWh and 640kWh and other power.
[0024] The battery system 301 is also integrated with a step 302, a handrail 304 and a charging socket 305. As a preferred embodiment, an indirect field of view device 303 can also be integrated as required. Specifically, taking the three battery systems 301 provided in the present application as an example, an indirect field of view device 303 is respectively integrated on the outer side surfaces of the two battery systems 301 located on the outside of the vehicle body, and the indirect field of view device 303 is arranged on the outer side surface of the battery system 301 close to the cabin module 200. In addition, the charging socket 305 is integrated on the upper surface of a battery system 301 close to the outside of the vehicle body, and the step 302 and the handrail 304 are arranged on the upper surface of another battery system 301 close to the outside of the vehicle body, and the charging socket 305, the step 302 and the handrail 304 are all arranged on the upper surface of the battery system 301 close to the cabin module 200. Figure 4 The above configuration makes the energy storage module 300 more integrated, reduces weight, reduces costs, improves reliability, and improves efficiency.
[0025] The chassis arrangement structure of the present application further includes: a brake pipe 501 and a high-voltage line 502 arranged in one longitudinal beam of the load-bearing frame 100, and a low-voltage line 503 and a water pipe 504 arranged in another longitudinal beam, see Figure 6 and Figure 7 As shown, in one embodiment of the present application, the brake pipe 501 and the high-voltage line 502 are arranged in the left longitudinal beam 101, and the low-voltage line 503 and the water pipe 504 are arranged in the right longitudinal beam 102. The cross-sectional structure of the left longitudinal beam 101 and the right longitudinal beam 102 is a U-shaped structure, and there is a receiving space inside. As a preferred embodiment, the high-voltage line 502 is located above the brake pipe 501, and the low-voltage line 503 is located above the water pipe 504, as shown in FIG. Figure 6 As shown. This setting realizes the separation of high and low voltage and water and electricity pipelines, thereby avoiding electromagnetic interference and signal loss caused by the mutual influence between high-voltage and low-voltage lines, and improving the reliability of the whole vehicle. The high-voltage line 502 and the low-voltage line 503 are arranged above the space of the longitudinal beam, and the brake pipe 501 and the water pipe 504 are arranged below the space of the longitudinal beam, and the water and electricity are separated, which reduces the corrosion of the wiring harness and the short circuit of the circuit caused by leakage, and improves the reliability and safety of the whole vehicle.
[0026] In one embodiment, the driving module 400 includes an air storage tank 401, and the air storage tank 401 is arranged below the balance shaft tube beam 105 of the load-bearing frame 100. Figure 2 and Figure 5 Specifically, the gas storage tank 401 is installed below the balance shaft pipe beam 105 through a bracket. In the present application, the balance shaft pipe beam 105 is preferably configured as a structure adapted to the bracket, so as to further facilitate the installation of the gas storage tank 401, enhance component reuse, reduce maintenance costs, and improve reliability.
[0027] In a preferred embodiment, two gas storage tanks 401 are arranged side by side, and their length direction is parallel to the longitudinal beam, and both are arranged below the balance shaft tube beam 105. Figure 5 shown.
[0028] like Figure 5 As shown, an electric drive bridge 104 is arranged on the axle 107 at the rear of the load-bearing frame 100, and the electric drive bridge 104 and the gas storage tank 401 are solidified into a module unit, which is arranged at the driving module 400. Based on different driving requirements, the electric drive bridge 104 can select an electric drive bridge with an MCU (Motor Controller Unit) and a power take-off, or an electric drive bridge with an MCU and without a power take-off, or an electric drive bridge with a power take-off without an MCU, or an electric drive bridge without an MCU and without a power take-off, or an electric wheel.
[0029] In one embodiment of the present application, Figure 3 As shown, a condenser 201, a cooling unit 202, an electronic fan 203, an electric device 204, an all-in-one electric drive system 205, a battery cooling system 206, a BMS (Battery Management System) device 207, a low-voltage battery 208, a power mechanical switch 209, an intelligent power distribution unit 210 and an air-conditioning compressor 211 are arranged in the cabin module 200.
[0030] Specifically, the arrangement of the components in the cabin module 200 may be as follows: Figure 3 Specifically, the condenser 201, the cooling unit 202 and the electronic fan 203 are solidified into a first module 200-1, which is arranged in the space near the vehicle head and one side longitudinal beam in the cabin module 200. Figure 3 is a top view of the cabin module 200, Figure 3 For illustration, the first module 200-1 is located at the front end of the cabin module 200 near the vehicle head. According to different heat dissipation power requirements and taking into full consideration the efficient use of the layout space, the electronic fans 203 can be preferably arranged in 1 to 3 groups. Of course, the actual number of groups to be arranged needs to be analyzed according to specific circumstances.
[0031] The electric device 204, the all-in-one electric drive system 205, the battery cooling system 206 and the BMS device 207 are solidified into a second module 200-2, which is arranged in the cabin module 200 adjacent to the first module 200-1 and distributed along the longitudinal beam direction. Figure 3As shown, relative to the first module 200-1, the second module 200-2 is located as a whole at the rear end of the cabin module 200 away from the front of the vehicle. The above-mentioned electric equipment 204 includes an electric air compressor and an electric steering pump, and the BMS equipment 207 includes a BMS distribution box and a BMS control box. Taking into full consideration the maintainability, rationality of the layout space and high efficiency, the electric air compressor and the electric steering pump can be integrated or non-integrated; similarly, the BMS distribution box and the BMS control box can be integrated or non-integrated. In addition, taking into full consideration the different electric drive structures and layout space issues, the all-in-one electric drive system 205 can be selected as a four-in-one electric drive system or a five-in-one electric drive system or a six-in-one electric drive system, etc., which is not specifically limited here.
[0032] like Figure 3 As shown, the low-voltage battery 208, the power mechanical switch 209 and the intelligent power distribution unit 210 are solidified into the third module 200-3 and are arranged in the space near the longitudinal beam on the other side of the cabin module 200. The positive power line is shorter, the modularization is higher, and the reliability of the whole vehicle is improved. The air-conditioning compressor 211 is arranged adjacent to the third module 200-3, and the rationality and efficiency of the layout space are fully considered in the refrigeration demand. The layout of the air-conditioning compressor 211 is arranged to be compatible with different displacement specifications, so as to achieve a reasonable layout, a high degree of modularization, and a high space utilization rate. In addition, when the modularization is higher, it also avoids the situation where each component needs a corresponding bracket for installation. It only needs to set a bracket corresponding to the module unit, so that the vehicle weight reduction effect is achieved to a certain extent.
[0033] As a preferred embodiment, see Figure 3, the electric device 204 and the all-in-one electric drive system 205 are arranged in an upper and lower structure, and the all-in-one electric drive system 205 is arranged above the electric device 204; the battery cooling system 206 and the BMS device 207 are arranged in an upper and lower structure, and the BMS device 207 is arranged above the battery cooling system 206.

Taking into full consideration the cooling principle type, maintainability, and rationality and efficiency of the layout space, the battery cooling system 206 can be an independent cooling unit or an integrated cooling unit. The various components of the cabin module 200 of the present application are designed in a large set, assembled offline, and hoisted as a whole to improve assembly efficiency, while achieving weight reduction and cost reduction. In addition, the electric equipment 204 and the battery cooling system 206 are arranged below the cabin module 200, and the all-in-one electric drive system 205 and the BMS equipment 207 are arranged above the cabin module 200. Based on the maintenance frequency of key components and the layout space requirements, the characteristics of high space utilization and good maintenance processability are achieved.
[0034] In addition, with respect to the spatial arrangement of the first module 200 - 1 , in one embodiment of the present application, the condenser 201 , the cooling unit 202 , and the electronic fan 203 are sequentially distributed from the front of the vehicle to the rear of the vehicle and solidified into the first module 200 - 1 .
[0035] In addition, in order to facilitate the inspection and maintenance of the components at the bottom of the chassis, the present application preferably sets a movable door on the bracket below the cabin module 200, and the internal components can be inspected and repaired by opening the movable door, which is more convenient to operate. The above movable door can be multiple movable doors set at different positions, or a movable door as a whole, mainly for safety, convenient maintenance and easy opening and closing.
[0036] In addition, a cross beam 103 and a tail beam 106 are arranged between the left longitudinal beam 101 and the right longitudinal beam 102 of the load-bearing frame 100 of the present application.

Two axles 107 are arranged near the rear of the vehicle on the load-bearing frame 100, such as Figure 2 and Figure 5 As shown, the air storage tank 401 is arranged on the balance shaft tube beam 105 between the two axles 107.
