Description

Technical Field

[0001] The present invention relates to the technical field of vehicle cooling, and in particular to a vehicle cooling system. Background Art

[0002] Existing vehicle cooling systems typically use an air intake device to control the air intake volume by adjusting the air inlet opening to meet the vehicle's cooling needs under different operating conditions. However, this design has certain technical drawbacks. Specifically, the size of the air inlet opening directly affects the amount of wind resistance. If the air inlet opening is too large, while it can increase the air intake volume, it will lead to a significant increase in wind resistance, thus affecting the vehicle's driving efficiency and energy consumption. On the other hand, if the air inlet opening is too small, while it can reduce wind resistance, it may result in insufficient air intake, affecting the cooling system's heat dissipation performance. Especially under high-load conditions, it may cause engine overheating, affecting the vehicle's stability and reliability.

[0003] Hybrid mining vehicles, due to their complex operating environments, place higher demands on their cooling systems. Existing air intake designs struggle to effectively reduce wind resistance while maintaining cooling performance. This leads to increased energy consumption and unstable heat dissipation during operation, which in turn affects the vehicle's overall performance and service life.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1-8 , the figure shows a vehicle cooling system, including an air intake assembly 1, which is installed at the front of the vehicle, in front of the engine compartment, and the air intake assembly 1 includes an air intake box 11, and air outlets 14 are provided on both sides of the air intake box 11. An adjustment mechanism 3 is provided inside the air outlet 14, and the adjustment mechanism 3 includes a box body 31 fixedly installed inside the air outlet 14, and one side of the box body 31 located in the air intake box 11 is open. A baffle 33 is provided inside the box body 31, and a slide groove 35 adapted to the baffle 33 is provided on the inner surface of the box body 31. The baffle 33 is slidably installed in the slide groove 35, and one side of the baffle 33 passes through the outside of the box body 31 and is provided with a moving mechanism 4; The moving mechanism 4 can drive the two groups of baffles 33 to move in opposite directions, controlling the opening of one group of the boxes 31 to expand and the opening of the other group of the boxes 31 to shrink, and the expansion or contraction of the openings of the two groups of the boxes 31 are the same.

[0019] Furthermore, it also includes a heat dissipation component 2, which includes a ventilation pipe 21 and a driving device 22. The driving device 22 is fixedly connected to one group of boxes 31 through the ventilation pipe 21, and the outer surface of the other group of boxes 31 is fixedly connected with an exhaust pipe 34.

[0020] Furthermore, a grille plate 12 is provided at the inlet of the air inlet box 11 , and the four corners of the grille plate 12 are connected to the air inlet box 11 by inserting mounting bolts 13 .

[0021] In this embodiment, one set of boxes 31 uses the ventilation pipe 21 to direct airflow into the driving device 22 to dissipate heat from the driving device 22, and the other set of boxes 31 discharges the airflow out of the vehicle through the exhaust pipe 34; In this embodiment, when the vehicle is driving, the airflow passes through the grille plate 12 and enters the interior of the air inlet box 11, and by setting a moving mechanism 4 in conjunction with the two groups of baffles 33, the moving mechanism 4 can drive the two groups of baffles 33 to move in opposite directions, so that the opening of one group of boxes 31 is expanded and the opening of the other group of boxes 31 is reduced, and the expansion and reduction amplitudes of the openings are the same, thereby ensuring that the overall size of the openings of the two groups of boxes 31 remains unchanged, ensuring stable wind resistance, making the energy consumption of the vehicle stable during operation, and being able to ensure heat dissipation effect.

[0022] The air intake assembly 1 is located at the front of the vehicle and is designed to allow air to enter smoothly. When the vehicle is driving, oncoming air enters the air intake box 11 through the grille plate 12 and flows through the ventilation pipe 21 to the surface of the drive device 22, removing heat and reducing the temperature of the drive device 22. At the same time, a corresponding air filter can be installed at the end of the ventilation pipe 21 to filter out dust and impurities, ensuring that the incoming air is clean and preventing contamination of the drive device 22. The air filter is a conventional device, and the specific structure and working principle of the air filter are not detailed here.

[0023] It should be noted that the drive equipment 22 in the vehicle that requires cooling primarily includes the engine, electric motor, battery system, transmission, drive axle, brake system, and electronic control system. These devices generate a significant amount of heat during operation. In particular, the engine and electric motor can experience significant temperature increases under high load conditions. These devices must be maintained at their normal operating temperature to prevent overheating, which could lead to performance degradation or equipment damage.

[0024] Furthermore, the moving mechanism 4 includes a socket 32 ​​opened on the outer surface of the air inlet box 11, and the baffle 33 partially penetrates to the outside of the air inlet box 11 through the socket 32, and the socket 32 ​​is slidably connected to the baffle 33, and the baffle 33 is fixedly connected to a connecting plate 41 on one side of the outside of the air inlet box 11, and a connecting rod 43 is fixedly connected to the surface of the connecting plate 41, and the connecting rod 43 is parallel to the baffle 33, and the end of the connecting rod 43 away from the connecting plate 41 is fixedly connected to a first piston plate 44, and the outer surface of the first piston plate 44 is sleeved with a first cylinder 45, and one end of the first cylinder 45 is fixedly connected to the air inlet box 11, and the connecting rod 43 slides through the first cylinder 45, and the outer surface of the connecting rod 43 is sleeved with a spring 42, and the two ends of the spring 42 are respectively connected to the connecting plate 41 and the first cylinder 45, and an aerodynamic component 5 is arranged between the two groups of the first cylinders 45.

[0025] Furthermore, the pneumatic component 5 includes a second cylinder 51 fixedly mounted on both sides of the outer surface of the air inlet box 11, the two groups of the second cylinders 51 are located between the two groups of first cylinders 45, and a connecting pipe 52 is fixedly connected between the first cylinder 45 and the second cylinder 51 on the same side, and a second piston plate 53 is slidingly and sealingly connected inside the second cylinder 51, and a guide rod 54 is fixedly connected between the two groups of the second piston plates 53, and the guide rod 54 passes through the adjacent side of the two groups of second cylinders 51, and the guide rod 54 and the second cylinder 51 have a sliding clearance fit, and an electric push rod 56 is fixedly connected to the outer surface of the air inlet box 11, and the telescopic end of the electric push rod 56 is fixedly connected to a push plate 55, and the push plate 55 is fixedly connected to the guide rod 54, and the telescopic movement of the electric push rod 56 is inversely parallel to the guide rod 54, and the sliding clearance fit between the guide rod 54 and the second cylinder 51 can balance the internal and external pressures of the second cylinder 51, so as to facilitate the movement of the second piston plate 53 inside the second cylinder 51.

[0026] Furthermore, when the electric push rod 56 extends or contracts, one group of the second piston plates 53 discharges the gas in the corresponding second cylinder 51 , and another group of the second piston plates 53 draws the gas into the corresponding second cylinder 51 .

[0027] Furthermore, the first piston plate 44 and the first cylinder 45 are in sliding and sealing cooperation, and the connecting rod 43 and the first cylinder 45 are in sliding and sealing cooperation.

[0028] Furthermore, an annular plate 46 is fixedly connected to the side of the inner surface of the first cylinder 45 away from the spring 42, and a groove 47 is provided on the surface of the annular plate 46 and the first cylinder 45. By providing the groove 47, the internal and external pressures of the first cylinder 45 can be balanced, making it easier for the first piston plate 44 to move inside the first cylinder 45.

[0029] Furthermore, a sealing strip is fixedly connected to the inner surface of the chute 35 at the opening of the box body 31, and the baffle 33 slides and seals with the sealing strip. By providing the sealing strip, the sealing between the chute 35 and the baffle 33 can be ensured.

[0030] In this embodiment, the vehicle is equipped with a temperature sensor and controller. The temperature sensor provides feedback on the temperature of the drive unit 22. The controller controls the airflow assembly 5 to adjust the opening of the air inlet assembly 1 based on this temperature. The temperature sensor can be a thermistor, thermocouple, or infrared sensor to monitor the temperature of key components in real time. These sensors operate by sensing temperature changes, converting the temperature signal into an electrical signal, and transmitting it to the vehicle controller. Based on the received temperature data, the controller, using a pre-set algorithm or control logic, adjusts the opening of the air inlet assembly to optimize cooling performance and ensure that the drive unit 22 operates within the optimal temperature range, thereby improving vehicle efficiency and reliability.

[0031] The controller controls when and how long the electric push rod 56 extends and retracts. A single-chip microcomputer (MCU) can be used as the controller. This MCU consists of an arithmetic unit, memory, and input / output devices, effectively acting as a miniature computer. Compared to general-purpose microprocessors used in personal computers, MCUs emphasize self-sufficiency and cost savings. Their greatest advantages are their small size, allowing them to be placed inside an instrument. However, they also have limited storage capacity, simple input / output interfaces, and low power consumption. In this embodiment, the MCU model is not critical.

[0032] For the sake of convenience, the components connected to the ventilation pipe 21, such as the box body 31, the baffle 33, the first cylinder 45, and the second cylinder 51, are defined as ventilation parts; the components connected to the exhaust pipe 34, such as the box body 31, the baffle 33, the first cylinder 45, and the second cylinder 51, are defined as exhaust parts. When the temperature sensor detects that the temperature of the driving device 22 is higher than the set value, the temperature sensor transmits a signal to the controller, and the controller can drive the electric push rod 56 to move, so that the electric push rod 56 drives the guide rod 54 and the second piston plate 53 to move toward the side of the exhaust piece. The second piston plate 53 located on the side of the exhaust piece squeezes the gas in the second cylinder 51 into the inside of the first cylinder 45, pushing the first piston plate 44 and the baffle 33 to move, so that the opening of the box body 31 on the side of the exhaust piece is reduced; the second piston plate 53 located on the side of the ventilation piece draws the gas in the first cylinder 45 into the inside of the second cylinder 51, driving the first piston plate 44 and the baffle 33 to move, so that the opening of the box body 31 on the side of the ventilation piece is expanded, ensuring sufficient air intake, and being able to effectively dissipate heat for the driving device 22; in addition, in the above process, the springs 42 on the ventilation side and the exhaust side undergo corresponding elastic deformation. When the electric push rod 56 moves back, the spring 42 resets and can drive the connecting plate 41 and the baffle 33 and other structures to reset.

[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
