[0057] The present invention will be further explained below with reference to specific embodiments.

[0058] Please see Figures 1-10 The present invention provides an automotive radiator mounting structure, the automotive radiator mounting structure comprising:

[0059] The frame includes a fixed frame 1, a bracket 5, and a fixed base 6. The fixed frame 1 has a receiving groove 2 for placing a radiator. Side plates 12 are fixedly installed on both sides of the fixed frame 1, and a support shaft 11 is fixedly installed inside the side plate 12. The support shaft 11 is rotatably connected to the bracket 5. The fixed base 6 is fixedly installed at the end of the bracket 5.

[0060] An execution module for driving the support shaft 11 to rotate in order to adjust the working angle of the fixed frame 1 is provided inside the bracket 5;

[0061] A cleaning mechanism for cleaning the surface of the radiator, the cleaning mechanism being mounted on the fixed frame 1;

[0062] And a control system for adjusting the operating status of the actuator module according to the vehicle speed.

[0063] In embodiments of the present invention, a cleaning mechanism is used to clean the surface of the radiator, effectively removing dust and other impurities accumulated on the radiator surface, thereby improving heat dissipation and extending service life. By coordinating the control system and the execution module, the working angle of the radiator can be adjusted according to vehicle speed, maximizing the utilization of airflow resources. At high speeds, it improves the utilization rate of oncoming airflow and enhances heat dissipation efficiency; at low speeds / idle speeds, it optimizes fan airflow circulation and eliminates heat dissipation blind spots. Compared to existing technologies, the present invention, through the coordinated arrangement of the execution module, cleaning mechanism, and control system, avoids the problem that existing installation structures are mostly single-function, only have fixed functions, and have a relatively traditional structure, unable to adaptively adjust the angle according to vehicle speed, thus affecting the performance of the radiator.

[0064] In one embodiment of the present invention, please refer to Figures 1-10 The execution module includes:

[0065] The worm gear 19 is located inside the bracket 5 and is fixedly mounted on the support shaft 11;

[0066] Rotate the worm gear 18 installed in the bracket 5, the worm gear 18 meshing with the worm wheel 19;

[0067] And a second drive member 17 for driving the worm gear 18 to rotate, the second drive member 17 being located within the bracket 5; wherein the second drive member 17 is a motor equipped with a brake assembly.

[0068] In this embodiment, the second driving member 17 drives the worm gear 18 to rotate, which in turn drives the worm wheel 19 to rotate. The worm wheel 19 drives the support shaft 11 to rotate, thereby adjusting the working angle of the fixed frame 1. Since the heat sink is installed inside the fixed frame 1, the working angle of the heat sink can be adjusted synchronously.

[0069] In one embodiment of the present invention, please refer to Figures 1-10 The cleaning mechanism includes an adjustment box 9 fixed to the top of the fixed frame 1. A translation seat 8 is slidably installed inside the adjustment box 9, and a threaded rod 15 is rotatably installed inside the adjustment box 9. The translation seat 8 has an internal threaded hole that is threadedly connected to the threaded rod 15. The side of the adjustment box 9 has a first driving member 16 that drives the threaded rod 15 to rotate. A cleaning assembly is also provided on the translation seat 8. The first driving member 16 can be a combination structure of a motor and a reducer.

[0070] The cleaning component includes:

[0071] Support plate 7 is fixedly installed on the end of the translation seat 8 away from the adjustment box 9;

[0072] The second guide plate 3 is fixedly installed at the bottom of the support plate 7, and one end of the second guide plate 3 is an arc-shaped structure, while the other end of the second guide plate 3 is a straight structure.

[0073] A cleaning brush 13 for cleaning the radiator is fixedly installed at the end of the second guide plate 3;

[0074] And a first guide plate 4 is slidably installed at the bottom of the support plate 7. The support plate 7 is provided with an electric telescopic cylinder 14 for driving the first guide plate 4 to move. The first guide plate 4 has an arc-shaped structure, and both ends of the first guide plate 4 can fit against the second guide plate 3.

[0075] In this embodiment, the rotating threaded rod 15 drives the translation seat 8 to move, which in turn drives the support plate 7 to move. The support plate 7, by driving the second guide plate 3 to move, allows the cleaning brush 13 to clean the surface of the radiator. When not cleaning, the positions of the second guide plate 3 and the first guide plate 4 are as follows: Figure 6 As shown, in this state, the second guide vane 3 and the first guide vane 4 can be tightly connected. During vehicle operation, the wind will flow along the surface of the second guide vane 3, reducing wind noise caused by the second guide vane 3 and the first guide vane 4, while also reducing resistance and saving energy. During cleaning, the electric telescopic cylinder 14 will move the first guide vane 4 away from the second guide vane 3, causing the second guide vane 3 to separate from the first guide vane 4. Figure 5 As shown, during vehicle operation, the airflow is guided by the first deflector 4 into the second deflector 3, and ultimately directed to the cleaning brush 13. The airflow trajectory is as follows: Figure 5 As shown by the dotted arrow, the combined arrangement of the first guide plate 4 and the second guide plate 3 can guide the airflow to the working area of ​​the cleaning brush 13, effectively blowing away the dust on the surface of the radiator. In conjunction with the cleaning action of the cleaning brush 13, the cleaning effect is further improved, thereby improving the heat dissipation effect of the radiator and extending the service life of the radiator.

[0076] In one embodiment of the present invention, please refer to Figures 1-10 The control system includes a sensing module, an ECU control module, an execution module, and a human-machine interaction module;

[0077] The sensing module includes a core operating condition sensor group and an environmental auxiliary sensor group. The core operating condition sensor group is used to collect data on vehicle speed, radiator tilt angle, engine water temperature and airflow velocity. The environmental auxiliary sensor group is used to collect data on ambient temperature and vehicle body vibration frequency.

[0078] The ECU control module is electrically connected to the perception module, the execution module and the human-machine interaction module respectively. The ECU control module is embedded with a working condition-angle adaptive matching algorithm and a dynamic fault-tolerant regulation algorithm, and generates a target tilt angle instruction for the radiator based on the data collected by the perception module;

[0079] The execution module responds to the instruction from the ECU control module, drives the support shaft 11 to rotate so as to realize the adjustment of the working angle of the fixed frame 1, and realizes the adjustment of the working angle of the radiator by changing the angle of the fixed frame 1;

[0080] The human-machine interaction module supports switching between an automatic control mode and a manual control mode, allows customizing angle adjustment parameters, and is linked with the whole vehicle driving mode.

[0081] The core working condition sensor group includes a vehicle speed sensor, an angular displacement sensor, an engine water temperature sensor and an air flow velocity sensor 10;

[0082] The vehicle speed sensor is integrated in the automotive ABS system, with a measurement accuracy of ±1km / h and a data sampling frequency of 5Hz;

[0083] The angular displacement sensor is installed at the hinge joint of the support shaft 11 and the bracket 5, with a measurement accuracy of ±0.1° and a data sampling frequency of 15Hz;

[0084] The engine water temperature sensor is installed at the water outlet of the engine cylinder block, with a measurement accuracy of ±0.5°C and a data sampling frequency of 10Hz;

[0085] The air flow velocity sensor 10 is located on the windward side of the radiator, with a measurement accuracy of ±0.2m / s and a data sampling frequency of 8Hz.

[0086] The ambient auxiliary sensor group includes an ambient temperature sensor and a vibration sensor;

[0087] The ambient temperature sensor is located outside the engine compartment, with a measurement accuracy of ±1°C and a data sampling frequency of 5Hz;

[0088] The vibration sensor is installed on the fixed frame 1, with a measurement range of ±500Hz and a data sampling frequency of 20Hz.

[0089] In the working condition-angle adaptive matching algorithm in the ECU control module, under the vehicle speed high-speed working condition, the target tilt angle of the radiator is determined by the formula for calculation;

[0090] where θv-high is the high-speed basic angle based on vehicle speed: when 60<v≤100km / h, ; when v>100km / h, ;

[0091] is the correction value based on engine water temperature: when the engine water temperature T>100℃, ; when 80℃≤T≤100℃, ; when T<80℃, ; the value range of θv-high is 5°~8°, and the forward tilt direction is positive.

[0092] In the working condition-angle adaptive matching algorithm in the ECU control module, under the low speed / idle working condition where the vehicle speed v≤60km / h, the target tilt angle of the radiator is calculated by the formula ;

[0093] wherein, is the low-speed basic angle based on vehicle speed: when 30<v≤60km / h, ; when v≤30km / h or at idle, ; is the correction value based on airflow velocity: when the airflow velocity vf<2m / s, =−1; when 2m / s≤vf≤4m / s, =0; when vf>4m / s, ; has a value range of -5°~-3°, and the backward tilt direction is negative.

[0094] The angle locking determination for bumpy road conditions of the dynamic fault-tolerant adjustment algorithm satisfies the formula f×t≥200×1;

[0095] In the formula, f is the vehicle body vibration frequency (unit: Hz) detected by the vibration sensor, t is the vibration duration (unit: s), "200" corresponds to "the critical value of the vibration frequency f (200Hz)", and "1" corresponds to "the critical value of the vibration duration t (1s)"; when the formula condition is satisfied, the ECU control module sends an angle locking instruction, the brake assembly operates to realize motor self-locking and stop angle adjustment; when f<50Hz and t<0.5s, the brake assembly stops operating and angle adjustment is resumed.

[0096] wherein the human-computer interaction module includes a vehicle-mounted central control display screen and steering wheel shortcut keys;

[0097] The resolution of the vehicle-mounted central control display screen is not lower than 1920×1080, it supports touch operation, can display the current tilt angle of the radiator, the target angle, engine water temperature and airflow velocity data in real time, and provides a custom interface for angle adjustment parameters;

[0098] The steering wheel shortcut buttons include a "mode switch button", an "angle + button", and an "angle - button". The "mode switch button" is used to switch between automatic control mode and manual control mode. The "angle ± button" is used to adjust the angle of the fixed frame in 0.5° increments in manual control mode.

[0099] The human-computer interaction module is linked to the vehicle's driving mode:

[0100] When the vehicle is in economy mode, the ECU control module will reduce the target tilt angle by 1°~2° under high-speed conditions to reduce wind resistance and reduce energy consumption.

[0101] When the vehicle is in Sport mode, the ECU control module will trigger the target tilt angle for high-speed conditions 1°~2° in advance (e.g., when the vehicle speed is 50km / h, the target angle is calculated according to the high-speed condition formula), and at the same time reduce the tilt angle for low-speed conditions by 0.5°~1° to adapt to the heat dissipation requirements of the engine when it outputs high power.

[0102] When the vehicle is in standard mode, the ECU control module uses the default operating condition-angle matching logic to balance heat dissipation efficiency and energy consumption.

[0103] In this embodiment, the system is based on "full-condition data-driven, multi-module collaborative response". Through a closed-loop process of data collection by the sensing module, calculation and decision-making by the ECU control module, action feedback by the execution module, and dynamic adaptation by the human-machine interaction module, it realizes intelligent adjustment of the radiator angle. The specific working method is as follows:

[0104] The core operating condition sensor group and the environmental auxiliary sensor group synchronously collect data at a preset sampling frequency (5Hz~20Hz): the vehicle speed sensor obtains real-time vehicle speed from the ABS system, the angle displacement sensor converts the rotation angle at the hinge into an electrical signal (accuracy ±0.1°), the engine coolant temperature sensor provides feedback on coolant temperature through the change in the resistance of the thermistor, and the airflow velocity sensor detects the airflow velocity on the windward side through a hot-film probe; the ambient temperature sensor and vibration sensor capture the external temperature and humidity and the vehicle body vibration frequency, respectively, forming a multi-dimensional data matrix covering "operating condition-environment-structural state".

[0105] The ECU control module filters the collected raw data: it uses a Kalman filter algorithm to eliminate high-frequency noise (such as instantaneous fluctuations in vehicle speed caused by bumps) in the vehicle speed and airflow velocity data, and uses a moving average filter to smooth the water temperature data (avoiding instantaneous errors from the water temperature sensor); at the same time, it sets data validity thresholds (such as vehicle speed range 0~250km / h, water temperature -40℃~150℃). If the data exceeds the threshold or there is no change after 3 consecutive samplings, it is determined that the sensor has failed, and the backup data model is immediately triggered to ensure reliable data input.

[0106] The ECU first classifies operating conditions based on vehicle speed data: when the vehicle speed is >60km / h, the high-speed target angle algorithm is activated (formula). When the vehicle speed is ≤60km / h or idling, the low-speed / idling condition algorithm is activated (formula). If the vibration sensor detects a vibration frequency f×t≥200×1, the angle adjustment algorithm is paused, and the bump lock logic is executed first.

[0107] Multi-parameter collaborative correction is as follows:

[0108] Under high-speed conditions: calculated based on vehicle speed Based on, combined with water temperature Correction: When the water temperature is >100℃ (high engine load), tilt forward an additional 1° to enhance heat dissipation; when the water temperature is <80℃ (low load), reduce the tilt forward by 1° to avoid overcooling. Also, refer to the ambient temperature: when the outside temperature is <0℃, further reduce the tilt forward by 0.5° to prevent condensation on the radiator core due to low temperature.

[0109] Under low-speed conditions: calculated based on vehicle speed Based on airflow velocity Correction: When the airflow velocity is <2m / s (fan-dominated cooling), tilt back an additional 1° to improve fan airflow utilization; when the airflow velocity is >4m / s (strong natural airflow), reduce the tilt back by 1° to balance airflow, and link with driving mode: reduce the tilt back by 0.5°~1° in sport mode to adapt to high power cooling requirements in advance.

[0110] This control system can adapt to different driving conditions and maximize the use of airflow resources:

[0111] When driving at high speeds, it improves the utilization of oncoming airflow and enhances heat dissipation efficiency;

[0112] At high speeds (vehicle speed > 60 km / h), airflow is the core heat dissipation medium for the radiator. This is achieved by tilting the radiator forward by 5°~8° (as described in the previous formula). The computational logic allows for a better incident angle between the oncoming airflow and the radiator core, enabling the airflow to smoothly pass through the forward-leaning core surface, reducing "impact loss" at the front end of the core and "vortex dead angle" at the rear. This directly solves the problems of low airflow utilization and insufficient heat dissipation at high speeds caused by traditional fixed angles (mostly 0°), preventing the engine from triggering "overheat protection" (power limitation) under high load and ensuring stable power output.

[0113] At low speed / idle speed, optimize fan airflow circulation and eliminate heat dissipation blind spots;

[0114] At low speeds (≤60km / h) or idling, natural airflow is weak, and heat dissipation mainly relies on the fan. Tilt the radiator back 3°~5° (as per the formula above). (Computational logic), the airflow blown by the fan passes through the heat sink to improve the heat dissipation effect.

[0115] This control system can also coordinate dynamic correction of multiple parameters to balance heat dissipation and energy consumption requirements:

[0116] Combined with water temperature regulation: avoid excessive or insufficient heat dissipation;

[0117] The angle adjustment is not a fixed pattern, but rather dynamically corrects itself based on the engine coolant temperature: when the coolant temperature is >100℃ (high load), the forward tilt angle increases by an additional 1° at high speeds and the backward tilt angle decreases by 0.5° at low speeds, enhancing heat dissipation; when the coolant temperature is <80℃ (low load), the forward tilt angle decreases by 1° at high speeds and the backward tilt angle increases by 0.5° at low speeds, preventing the radiator from overcooling and slowing down the engine warm-up (especially in winter). This "coolant temperature-angle" linkage ensures that the engine operates within its optimal temperature range of 85℃~95℃ for over 95% of the time, guaranteeing heat dissipation while reducing fuel / electricity waste caused by temperature fluctuations.

[0118] By controlling the angle precisely and dynamically, the heat dissipation efficiency is maximized, energy loss is minimized, and system risk is reduced. This effectively avoids the problem of the single function of existing installation structures. The installation structure of this invention can effectively utilize the performance of the radiator and improve the heat dissipation effect.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.
