Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of vehicles, in particular, to a vehicle. BACKGROUND

[0002] In the arrangement of the whole vehicle, the radiator of the power component needs to occupy an independent space as an independent accessory, which affects the space arrangement of other components in the vehicle cabin, makes the available space of other components smaller, and the utilization rate of the overall cabin space is low. In addition, the radiator arranged as an independent accessory in the vehicle cabin is also easy to produce larger noise and vibration, which affects the NVH (Noise, Vibration, Harshness) performance of the whole vehicle. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present disclosure is to provide a vehicle to reduce the space occupied by the radiator in the vehicle and improve the utilization rate of the cabin space.

[0004] In order to achieve the above purpose, the present disclosure provides a vehicle, comprising:

[0005] a vehicle body, which is formed with a passenger cabin and a power cabin arranged adjacent to each other along the front-rear direction of the vehicle;

[0006] a power component arranged in the power cabin; and

[0007] a radiator arranged adjacent to the power component along the front-rear direction of the vehicle and connected with the vehicle body, wherein the radiator is located on the side of the power component away from the passenger cabin, and the hardness of the radiator is lower than the hardness of the power component and the hardness of the vehicle body.

[0008] Optionally, the vehicle further comprises a fan capable of cooling the radiator, wherein the fan is connected to the radiator.

[0009] Optionally, the fan is located between the power component and the radiator, the radiator is formed with a plurality of through holes in communication with the fan, and the air on the side of the radiator away from the fan can be guided to the fan through the radiator to cool the radiator.

[0010] Optionally, the radiator is made of aluminum material, and the vehicle body is made of steel material.

[0011] Optionally, the vehicle further comprises a heat dissipation circuit in communication with the power component and the radiator, the heat dissipation circuit can circulate the cooling liquid between the power component and the radiator, so that the radiator dissipates heat for the power component.

[0012] Optionally, the power component is an engine, the engine includes an engine exhaust pipe, the radiator includes a radiator exhaust pipe, and the vehicle also includes an expansion tank. The inlet of the expansion tank is connected to the engine exhaust pipe and the radiator exhaust pipe, respectively, and the outlet of the expansion tank is connected to the cooling circuit. The expansion tank is used to collect water from the engine exhaust pipe and the radiator exhaust pipe and replenish the water into the cooling circuit.

[0013] Optionally, the connection between the expansion tank and the heat dissipation circuit is located at the liquid inlet end of the power component.

[0014] Optionally, the vehicle further includes a heating branch, which is equipped with a heater tank for heating the vehicle interior. The heating branch is connected in parallel to the heat dissipation circuit, and the outlet of the heating branch is connected to the inlet of the power unit.

[0015] Optionally, the heat dissipation circuit further includes a thermostat located at the liquid inlet end of the power component.

[0016] Optionally, the vehicle body has a power compartment, the power unit is disposed in the power compartment, the power compartment is located at the front of the vehicle, and the radiator is located at the front of the power unit and forms the front bumper beam of the vehicle.

[0017] By fixing the radiator of the power unit to the vehicle body using the above technical solution, the radiator can form a crash beam for the vehicle. Since the hardness of the radiator is lower than that of the power unit and the vehicle body, when the radiator is impacted, its lower hardness allows it to form a crumple zone with the power unit and vehicle body behind it, reducing the impact energy transmitted to the passenger compartment. This provides a buffer for sudden deceleration of the vehicle and reduces the maximum potential damage to passengers in the passenger compartment. Furthermore, fixing the radiator to the vehicle body not only improves component integration and reduces costs associated with logistics, production, material management, and maintenance, thus lowering the overall vehicle cost, but also reduces noise and vibration transmission, optimizing the vehicle's NVH (Noise, Vibration, Harshness) performance.

[0018] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In this disclosure, unless otherwise stated, directional terms such as "front" and "rear" are defined in relation to the actual direction of the vehicle's movement, and directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0027] According to one embodiment of this disclosure, such as Figures 1 to 3 As shown, a vehicle is provided, including a power unit 1, a radiator 2, and a body 7. The body 7 has an adjacent passenger compartment 70 and a power compartment 71 formed along the longitudinal direction of the vehicle, and the power unit 1 is disposed in the power compartment 71. The radiator 2 is disposed adjacent to the power unit 1 along the longitudinal direction of the vehicle and connected to the body 7, wherein the radiator 2 is located on the side of the power unit 1 away from the passenger compartment 70, and the hardness of the radiator 2 is lower than the hardness of the power unit 1 and the hardness of the body 7.

[0028] Through the above technical solution, the radiator 2 of the power component 1 is fixedly connected to the vehicle body 7, allowing the radiator 2 to form a collision protection beam for the vehicle. Since the hardness of the radiator 2 is lower than that of the power component 1 and the vehicle body 7, when the radiator 2 is impacted, due to its lower hardness compared to the power component 1 and the vehicle body 7 behind the impact point, the radiator 2 can form a crumple zone with the power component 1 and the vehicle body 7 behind it, reducing the collision energy transmitted to the passenger compartment 70. This provides a certain buffer for the sudden deceleration of the vehicle and can reduce the maximum potential damage to passengers inside the passenger compartment 70. Simultaneously, the fixed connection between the radiator 2 and the vehicle body 7 not only improves component integration and reduces costs in logistics, production, material management, and maintenance, thereby reducing the overall vehicle cost, but also reduces noise and vibration transmission, optimizing the vehicle's NVH (Noise, Vibration, Harshness) performance.

[0029] It should be noted that the radiator 2 can be made of aluminum, and the body 7 can be made of steel. Steel is harder than aluminum, allowing the body 7 and radiator 2 to form a crumple zone structure. The radiator 2 can also be made of soft, low-carbon steel; this disclosure does not limit its use. Regarding the structure of the radiator 2 itself, it can consist of cooling pipes and multiple fins. The interior of the cooling pipes forms a space for gas or liquid flow, and the cooling pipes extend along the width of the vehicle and connect to the body 7. Here, there can be multiple cooling pipes arranged at intervals along the height direction; this disclosure does not limit their use. Multiple fins can be connected at intervals on the side of the cooling pipes away from the power component 1, and the multiple fins can be arranged at intervals along the width of the vehicle. The fins can be located on the outermost side, so that when the vehicle is impacted, the fins can be impacted first. When the impact force is large, because the hardness of the fins is lower than that of the rear body 7, the fins collapse and absorb some of the impact energy, reducing the impact energy transmitted to the next position of the body 7, thereby reducing the impact energy received by the passengers and minimizing the maximum potential damage to them. Specifically, the radiator 2 can be used in passenger vehicles or freight vehicles, and this disclosure does not limit it.

[0030] Specifically, depending on the vehicle's power type, the power compartment 71 can be located at either the front or rear of the vehicle; this disclosure does not limit this. When the power compartment 71 is located at the front of the vehicle, the radiator 2 can be located at the front of the power component 1, forming a front anti-collision beam. When the power compartment 71 is located at the rear of the vehicle, the radiator 2 can be located at the rear of the power component 1, forming a rear anti-collision beam. As mentioned above, the hardness of the radiator 2 can be lower than the hardness of the body 7. The body 7 also includes a passenger compartment located behind the power compartment 71. Thus, the hardness of the radiator 2 can be lower than the hardness of the power compartment 71 portion of the body 7 and the hardness of the power component 1. The hardness of the power component 1 and the power compartment 71 portion of the body 7 can be lower than the hardness of the passenger compartment portion of the body 7, making the radiator 2, power compartment 71, and passenger compartment form a stepped crumple zone structure to further protect occupants and improve the overall vehicle safety.

[0031] Furthermore, such as Figures 1 to 3 As shown, the vehicle also includes a fan 6 capable of cooling the radiator 2, wherein the fan 6 is connected to the radiator 2. This reduces the connection distance to the radiator 2 and improves the heat dissipation effect on the radiator 2.

[0032] Furthermore, such as Figures 1 to 3 As shown, fan 6 is located between power unit 1 and radiator 2. Radiator 2 has multiple through holes 22 communicating with fan 6, which allow air from the side of radiator 2 away from fan 6 to pass through radiator 2 and be directed to fan 6 to cool radiator 2. In other words, fan 6 can draw in external cold air and pass it through radiator 2 to cool radiator 2. The heated air then enters the power compartment 71 mentioned below. The bottom of the vehicle's power compartment 71 is unobstructed; therefore, the heated air can be exhausted from the bottom of the power compartment 71 to reduce the impact on power unit 1.

[0033] According to one embodiment of this disclosure, such as Figure 1 and Figure 3 As shown, the vehicle also includes a cooling circuit 3 connecting the power unit 1 and the radiator 2, so that coolant can circulate between the power unit 1 and the radiator 2, allowing the radiator 2 to dissipate heat from the power unit 1. The components of the coolant can be added according to actual needs, and this disclosure does not limit them.

[0034] Specifically, the power component 1 can be an engine, which includes an engine exhaust pipe 11, and the radiator 2 includes a radiator exhaust pipe 21. The vehicle also includes an expansion tank 4. The inlet of the expansion tank 4 is connected to both the engine exhaust pipe 11 and the radiator exhaust pipe 21, and the outlet of the expansion tank 4 is connected to the cooling circuit 3. The expansion tank 4 is used to collect moisture from the engine exhaust pipe 11 and the radiator exhaust pipe 21 and replenish the moisture into the cooling circuit 3. The function of the expansion tank 4 is to accommodate the expansion of the liquid in the engine system. Since the liquid will evaporate when heated, the gas discharged from the engine exhaust pipe 11 and the radiator exhaust pipe 21 contains moisture. The expansion tank 4 connects the engine exhaust pipe 11 and the radiator exhaust pipe 21, collects the moisture, replenishes the cooling circuit 3, and discharges the gas, effectively preventing moisture loss from the engine system, reducing hydraulic fluctuations caused by liquid expansion, and improving the safety of system operation. Here, the engine exhaust pipe 11 is connected to the coolant lines in the engine. While the engine is working, coolant enters the engine from the cooling circuit 3 and heats up. After heating, the coolant expands and evaporates. The evaporated vapor enters the engine exhaust pipe 11, which is connected to the expansion tank 4. The expansion tank recovers the water in the engine exhaust pipe 11. The coolant temperature is still high when it enters the radiator 2 from the engine exhaust pipe. Therefore, the coolant lines in the radiator 2 are connected to the radiator exhaust pipe 21, which is connected to the expansion tank 4. This allows the vapor generated by the coolant evaporation at high temperatures to be sent to the expansion tank 4, where the expansion tank 4 recovers the water in the radiator exhaust pipe 21. Since the liquid added to the expansion tank 4 and the heat dissipation circuit 3 is cooled liquid, the connection between the expansion tank 4 and the heat dissipation circuit 3 can be located at the liquid inlet end of the power component 1. In this way, when the expansion tank 4 adds liquid to the heat dissipation circuit 3, it can directly add liquid to the side that has not been heated by the power component 1, so that the temperature of the added liquid is close to the temperature of the liquid in the heat dissipation circuit 3, thereby reducing the impact on the heat dissipation circuit 3.

[0035] In addition, such as Figure 3As shown, the vehicle may also include a heating branch 5, on which a heater core 51 for heating the vehicle interior is installed. The heating branch 5 is connected to the cooling circuit 3, and the outlet of the heating branch 5 is connected to the inlet of the power unit 1, while the inlet of the heating branch 5 is connected to the outlet of the power unit 1. The coolant in the cooling circuit 3 will heat up after passing through the power unit 1. When heating the vehicle interior is required, the cooling circuit 3 and the heating branch 5 are connected, and the heated coolant can partially enter the heating branch 5 for circulation to raise the temperature of the water in the heater core 51. In this way, the air temperature near the heater core 51 will increase. The heater core 51 can be connected to a blower. When heating the vehicle interior is required, the blower can be started, and the blower can blow the already heated air near the heater core 51 into the vehicle interior to heat the interior. In this way, the heater core 51 can both provide heat to the vehicle interior and reduce the heat dissipation pressure of the radiator 2. After the heat is supplied, the coolant that has cooled down enters the heat dissipation circuit 3 through the heat supply branch 5 and mixes with the coolant that has cooled down after being cooled by the radiator 2, and then enters the power unit 1 for circulation again.

[0036] Regarding the flow regulation method for heat dissipation circuit 3, such as Figure 3 As shown, the cooling circuit 3 may also include a thermostat 31, which is located at the liquid inlet of the power component 1. The thermostat 31 can automatically control the flow rate of the cooling circuit 3 according to the liquid temperature in the cooling circuit 3. That is, when the liquid temperature in the cooling circuit 3 is high, the flow rate of the cooling circuit 3 is increased, and when the liquid temperature in the cooling circuit 3 is low, the flow rate of the cooling circuit 3 is decreased, thereby ensuring that the power component 1 operates within a suitable temperature range. Here, it should be noted that the thermostat 31 can not only regulate the flow rate but also act as a valve. The connection between the outlet of the heating branch 5 and the cooling circuit 3 can be located between the liquid inlet of the power component 1 and the thermostat 31. Taking the power component 1 as an engine as an example, when the engine coolant temperature is low, the thermostat 31 can be in the closed state. In this way, only the heating branch 5 participates in the engine's water circulation, and the radiator 2 cannot participate in the engine's circulation and dissipate heat through the cooling circuit 3. This can reduce the energy dissipation when the engine is working, allowing the engine temperature to rise quickly and reach the normal operating temperature of the engine quickly. When the engine coolant temperature is high, the thermostat 31 opens, and the radiator 2 participates in the heat dissipation work, which can quickly reduce the engine temperature, prevent the engine from overheating, and keep the engine at the normal operating temperature. A pump 32 connected to the power unit 1 can also be installed on the cooling circuit 3 to regulate the liquid pressure entering the power unit 1 from the cooling circuit 3.
