If there is no conflict, the embodiments of the utility model and the various features in the embodiments can be combined with each other, all within the protection scope of the utility model.
[0046] Pantograph vehicles are usually used on electrified roads. When there is a contact network section, the vehicle can continuously transmit the contact network's electric energy to the power device through the pantograph to drive the vehicle. In sections without a contact network, the transportation operation can be completed by relying on the engine or power battery pack.
[0047] In the related art, a chassis structure of a pantograph vehicle includes a power battery, a pantograph, a motor, a vehicle controller and a motor controller. The motor is controlled by the motor controller, and the pantograph and the power battery are controlled by the vehicle controller.
[0048] However, in the related art, the motor controller and the vehicle controller are respectively connected to the cab via cables so that the driver can operate the motor controller and the vehicle controller, which makes the control line of the pantograph vehicle longer, resulting in a slower response speed of the power battery, pantograph and motor controller and a higher line laying cost of the vehicle.
[0049] In addition, the power battery, pantograph and vehicle controller are relatively dispersed on the chassis structure of the vehicle, and the distance between the vehicle controller and the power battery and pantograph is relatively long, which makes the control line connecting the vehicle controller to the power battery and pantograph longer, resulting in a slow response speed of the power battery and pantograph and a high line laying cost of the vehicle.
[0050] For the above technical issues, please see Figure 1 and Figure 2 The embodiment of the utility model provides a chassis structure of a pantograph vehicle, including: a frame 100 and a front axle assembly 110, a middle axle assembly 120 and a rear axle assembly 130 sequentially arranged on the frame 100; a pantograph assembly 200, the pantograph assembly 200 is arranged on the frame 100 and is located between the front axle assembly 110 and the middle axle assembly 120, and the pantograph assembly 200 is used to obtain electric energy from the contact network; a controller assembly 300, the controller assembly 300 is connected below the pantograph assembly 200, and the controller assembly 300 is used to control the operation of the pantograph assembly 200; an electric powertrain 400, the electric powertrain 400 includes an electrically connected power battery pack 410, a motor controller 420 and a motor 430, the power battery pack 410 and the motor controller 420 are both connected to the peripheral side of the controller assembly 300, and the controller assembly 300 is also used to control the operation of the power battery pack 410 and the motor controller 420.
[0051] The chassis structure of the pantograph vehicle provided by the utility model forms a basic framework of the chassis structure by providing a vehicle frame 100 and sequentially arranging a front axle assembly 110, a middle axle assembly 120 and a rear axle assembly 130 on the vehicle frame 100. The vehicle frame 100, the front axle assembly 110, the middle axle assembly 120 and the rear axle assembly 130 are all structural designs known in the art and are not described in detail herein.
[0052] By setting up the pantograph assembly 200, the pantograph assembly 200 is set on the frame 100 and is located between the front axle assembly 110 and the middle axle assembly 120. It can be used to obtain electrical energy from the contact network, thereby providing power for the operation of the vehicle.
[0053] By providing the controller assembly 300, the controller assembly 300 is used to control the operation of the pantograph assembly 200, and the controller assembly 300 is connected below the pantograph assembly 200, so that the control line of the controller assembly 300 for controlling the operation of the pantograph assembly 200 is shorter.
[0054] By setting up an electric powertrain 400, the electric powertrain 400 includes an electrically connected power battery pack 410, a motor controller 420 and a motor 430, and the controller assembly 300 is also used to control the operation of the power battery pack 410 and the motor controller 420, and the power battery pack 410 and the motor controller 420 are both connected to the peripheral side of the controller assembly 300, so that the control circuit of the controller assembly 300 to control the operation of the power battery pack 410 and the motor controller 420 is shorter.
[0055] In summary, the controller assembly 300 is connected below the pantograph assembly 200, and the power battery pack 410 and the motor controller 420 are both connected to the peripheral side of the controller assembly 300, so that the controller assembly 300 has a more centralized control over the power battery pack 410, the pantograph assembly 200, and the motor controller 420, and the control line of the pantograph vehicle is shorter.
[0056] Shorter control lines can reduce resistance and inductance losses when current passes through the lines, thereby reducing energy losses.
[0057] Shorter control lines can also reduce the delay time of signal transmission, allowing the signal to reach the power battery pack 410, the pantograph assembly 200, and the motor controller 420 more quickly, thereby improving the response speed of the entire control system.
[0058] Shorter control lines can also simplify the wiring process of the control system of the entire chassis structure, thereby reducing the number and length of control lines, thereby reducing the wiring cost of the pantograph vehicle.
[0059] In some embodiments, see Figure 1 and Figure 2 The chassis structure of the pantograph vehicle also includes an air conditioning and refrigeration assembly, which includes an air conditioning compressor 500, which is arranged on the vehicle frame 100, and is located on the side of the front axle assembly 110 away from the middle axle assembly 120, and the air conditioning compressor 500 is used to pressurize the refrigerant. In addition, the air conditioning compressor 500 is connected to the peripheral side of the controller assembly 300, and the controller assembly 300 is also used to control the operation of the air conditioning compressor 500. By connecting the air conditioning compressor 500 to the peripheral side of the controller assembly 300, the control line of the controller assembly 300 to control the operation of the air conditioning compressor 500 is shorter.
[0060] Furthermore, the air conditioning refrigeration assembly also includes: a condenser (not shown), which is arranged on the frame 100, the condenser is located on one side of the air conditioning compressor 500, and the condenser is used to cool the pressurized refrigerant; an electronic fan (not shown), which is arranged on the frame 100, the electronic fan is located on one side of the condenser, and the electronic fan is used to accelerate the cooling of the pressurized refrigerant.
[0061] In this embodiment, the condenser is located on one side of the air-conditioning compressor 500, that is, the condenser is adjacent to the air-conditioning compressor 500, and the distance between the condenser and the air-conditioning compressor 500 is relatively short. Since the condenser is connected to the air-conditioning compressor 500 through a pipeline, the distance between the condenser and the air-conditioning compressor 500 is relatively short, which shortens the length of the pipeline between the condenser and the air-conditioning compressor 500, thereby improving the cooling efficiency.
[0062] It should be noted that other structures of the air-conditioning refrigeration assembly are structural designs known in the art and will not be elaborated here.
[0063] In other embodiments, see Figure 1 and Figure 2 The chassis structure of the pantograph vehicle also includes a steering assembly, which includes an electric steering oil pump 600. The electric steering oil pump 600 is connected to the peripheral side of the controller assembly 300. The controller assembly 300 is also used to control the operation of the electric steering oil pump 600.
[0064] By connecting the electric steering oil pump 600 to the peripheral side of the controller assembly 300 , a control line of the controller assembly 300 for controlling the operation of the electric steering oil pump 600 is shortened.
[0065] Furthermore, the steering assembly also includes a steering mechanism (not shown), and the electric steering oil pump 600 and the steering mechanism are both arranged on the side of the pantograph assembly 200 away from the center axle assembly 120, and the electric steering oil pump 600 is also connected to one side of the steering mechanism.
[0066] Specifically, the electric steering oil pump 600 is connected to the steering mechanism through an oil pipe. The electric steering oil pump 600 is responsible for generating hydraulic pressure and delivering hydraulic oil to the steering system through the oil pipe to achieve the steering of the vehicle. In this embodiment, the electric steering oil pump 600 is connected to one side of the steering mechanism, so that the distance between the electric steering oil pump 600 and the steering mechanism is shorter, thereby shortening the length of the oil pipe, thereby improving the response speed of the vehicle steering.
[0067] It should be noted that the principle of the electric steering oil pump 600 cooperating with the steering mechanism to achieve vehicle steering is a prior art and will not be elaborated here.
[0068] In some other embodiments, see Figure 3 The chassis structure of the pantograph vehicle also includes an air brake assembly 700, which includes: an air cylinder 710, which is arranged on the frame 100 and is used to store air for braking; an electric air pump 720, which is connected to the air cylinder 710 and is also connected to the peripheral side of the controller assembly 300, and the controller assembly 300 is used to control the electric air pump 720 to inflate the air cylinder 710.
[0069] In this embodiment, the electric air pump 720 is connected to the peripheral side of the controller assembly 300, so that the control circuit of the controller assembly 300 for controlling the operation of the electric air pump 720 is shorter.
[0070] It should be noted that the principle of the electric air pump 720 and the air cylinder 710 cooperating to achieve vehicle braking is a prior art and will not be elaborated here.
[0071] In this utility model, please see Figures 1 to 3 The chassis structure of the pantograph vehicle also includes a thermal management assembly 800, which has a plurality of heat transfer pipes connected to the bottom of the pantograph assembly 200; the controller assembly 300, the power battery pack 410, the motor controller 420 and the motor 430 are connected to the surrounding side of the heat transfer pipes, and the heat transfer pipes are used to obtain the heat generated by the pantograph assembly 200, the controller assembly 300, the power battery pack 410, the motor controller 420 and the motor 430.
[0072] By connecting the heat transfer pipe of the thermal management assembly 800 below the pantograph assembly 200, and connecting the controller assembly 300, the power battery pack 410, the motor controller 420 and the motor 430 to the peripheral side of the heat transfer pipe, the distance between the heat transfer pipe and the controller assembly 300, the pantograph assembly 200, the power battery pack 410, the motor controller 420 and the motor 430 is relatively close, so that the heat transfer pipe used by the thermal management assembly 800 is shorter, thereby reducing the layout cost of the heat transfer pipe and improving the space utilization of the chassis structure.
[0073] Furthermore, the heat transfer pipe is an aluminum pipe, and there is coolant in the heat transfer pipe. The end of the heat transfer pipe is connected to the heat-generating components of the electric power assembly 400, the controller assembly 300 and the pantograph assembly 200, or the end of the heat transfer pipe is close to the heat-generating components of the electric power assembly 400, the controller assembly 300 and the pantograph assembly 200, and the coolant can obtain the heat generated by these heat-generating components.
[0074] In some embodiments, see Figure 1 The pantograph assembly 200 includes: a pantograph bracket 210, which is arranged on the frame 100; a pantograph battery (not shown), which is arranged on the frame 100 and located in the pantograph bracket 210; a pantograph unit 220, which is connected to the pantograph battery, and is used to obtain electrical energy from the contact network and store the obtained electrical energy in the pantograph battery.
[0075] In this embodiment, the pantograph bracket 210 has a certain rigidity, the pantograph battery is located in the pantograph bracket 210, and the pantograph bracket 210 can prevent other parts of the vehicle from contacting the pantograph battery so as to damage the pantograph battery; and the pantograph unit 220 is arranged on the pantograph bracket 210 and connected to the pantograph battery. The pantograph bracket 210 has a supporting effect on the pantograph unit 220, so that the pantograph unit 220 can stably contact the contact network.
[0076] In addition, the pantograph bracket 210 and the pantograph battery are used to be arranged behind the cab of the pantograph vehicle, and the pantograph unit 220 is used to extend above the cab, so that the entire pantograph assembly 200 is located at the front end of the frame 100, which will not affect the detachment and removal of the trailer of the pantograph vehicle.
[0077] Furthermore, the pantograph assembly 200 further includes a protective cover 230 , which is disposed on the vehicle frame 100 , and the pantograph bracket 210 and the pantograph battery are both located inside the protective cover 230 .
[0078] The protective cover 230 can not only prevent other parts of the vehicle from contacting the pantograph so as to damage the pantograph battery, but also prevent rainwater from contacting the pantograph battery so as to damage it. Therefore, the protective cover 230 can play a good protective role on the pantograph battery.
[0079] An embodiment of the utility model further provides a pantograph vehicle, comprising a vehicle body and a chassis structure of any of the above-mentioned pantograph vehicles connected to the vehicle body.
[0080] Specifically, the pantograph vehicle of this embodiment adopts all the technical solutions of the chassis structure of any of the aforementioned pantograph vehicles, and therefore has at least all the beneficial effects brought by the technical solutions of the aforementioned embodiments, which will not be described one by one here.
[0081] In some embodiments, the vehicle body includes a cab (not shown), which is disposed on a frame 100 of the chassis structure of the pantograph vehicle, and a power battery pack 410 of the chassis structure of the pantograph vehicle is located between the cab and the frame 100 .
[0082] If the device that may be frequently maintained is arranged under the cab, the cab needs to be turned over every time the device is maintained. Therefore, in this embodiment, the power battery pack 410 that does not require frequent maintenance is arranged between the cab and the frame 100, and the device that may be frequently maintained is arranged on the side of the cab instead of between the cab and the frame 100. When maintaining the device that may be frequently maintained, there is no need to frequently turn over the cab. Devices that may be frequently maintained include the motor controller 420 and the controller assembly 300 in the utility model.
[0083] In addition, arranging the power battery between the cab and the vehicle frame 100 can facilitate the connection of electrical appliances inside the cab.
