Description

Technical Field

[0001] This invention relates to the field of vehicle cooling technology, and more particularly to a variable intake air temperature grille system and vehicle. Background Technology

[0002] The core function of a vehicle's air intake grille is to provide the necessary cooling air to the engine. When the engine is running, it generates a significant amount of heat. The air intake grille guides outside air into the engine compartment, helping the radiator cool the engine and ensuring its efficient operation within a reasonable temperature range. Current vehicle air intake grilles typically achieve the purpose of keeping the vehicle warm during low-temperature conditions by opening and closing; however, the current cooling methods for vehicle air intake grilles rely solely on ambient temperature and rely on increasing fan speed, failing to address the load and stress that high-temperature air intake places on the vehicle's fan and cooling system. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a variable intake air temperature grille system and vehicle that utilizes the principle of compressed air to autonomously adjust the intake air temperature, thereby improving vehicle heat dissipation efficiency without increasing the electrical load.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] In a first aspect, embodiments of the present invention provide a variable intake air temperature grille system, comprising:

[0006] An air inlet baffle, wherein the air inlet baffle has a petal-shaped structure and multiple air inlet baffles are arranged sequentially along the circumference;

[0007] The traction assembly is installed on the outside of the air inlet baffle;

[0008] A pushing component is connected to a pulling component. The pushing component is used to drive the pulling component to tighten or expand each air intake baffle to autonomously adjust the air intake temperature.

[0009] As a further implementation, adjacent air inlet baffles are connected at one end to form an air inlet;

[0010] The other end of the air inlet baffle is tightened to form an air outlet, and a chamber for compressed air is formed between each air inlet baffle.

[0011] As a further implementation, the traction assembly includes a tensioning seat, a pulley, and a pulley support. One side of the tensioning seat is fixed to the air inlet baffle, and the other side is provided with a pulley track.

[0012] The pulley is installed on the pulley support, and the pulley support can drive the pulley to move along the pulley track under the action of the pushing component; when the pulley is at the top of the slide rail, the air inlet baffle is in a tightened state.

[0013] As a further implementation, the side of the tightening seat and the pulley support that are close to each other is an inclined surface, and the pulley track forms a set angle with respect to the air inlet baffle.

[0014] As a further implementation, the pulley support is provided with a fixing seat on the side away from the tensioning seat, and the fixing seat is used to generate a tension force on the pulley support to maintain its position.

[0015] As a further implementation, the surface of the fixed seat facing the pulley support is an inclined surface.

[0016] As a further implementation, the driving component includes a base plate and a linear power source, the linear power source being fixedly connected to the base plate;

[0017] Each tensioning component is connected to the base plate.

[0018] As a further implementation, a baffle spring is connected between adjacent air intake baffles.

[0019] As a further implementation, a temperature sensor is also included, and both the temperature sensor and the actuation component are connected to the controller;

[0020] The temperature sensor is used to detect the ambient temperature; the controller is used to control the pushing component to push the air inlet baffle to a tightened state when the ambient temperature is higher than a set threshold; and to control the air inlet baffle to expand to a set angle when the ambient temperature is lower than the set threshold.

[0021] Secondly, embodiments of the present invention also provide a vehicle equipped with the aforementioned variable intake air temperature grille system.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) The variable intake temperature grille system of the present invention includes multiple intake baffles. The intake baffles adopt a petal structure so that a cavity for compressed air can be formed between each intake baffle. Under the action of the pushing component, each intake baffle can move closer to each other to form a contracted state, or move further away from each other to form an expanded angle. That is, based on the principle of compressed air, the intake temperature can be autonomously adjusted.

[0024] By monitoring the ambient temperature with a temperature sensor and automatically controlling the push components, the air intake baffles can be tightened or expanded. This improves the vehicle's heat dissipation efficiency without increasing the electrical load, solving the problem of the vehicle's cooling system operating under high load due to excessively high intake air temperature. At the same time, by reducing the intake air temperature, it assists in vehicle heat dissipation, reducing heat loss of electrical components and shortening their lifespan due to high load operation.

[0025] (2) The present invention sets up a pulley track by tightening seat, and the pulley is installed on the pulley support so that the pulley can move along the inclined pulley track, thereby pushing the air inlet baffle to tighten or pulling the air inlet baffle to open; and a fixed seat is set up to maintain the movement trajectory of the air inlet baffle, making the whole system more stable.

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] Example 1:

[0032] This embodiment provides a variable intake air temperature grille system that utilizes biomimetic design, incorporating petal-shaped air intake baffles arranged inside the intake grille, and employing compressed air principles to achieve autonomous control of the intake air temperature; such as Figure 1 and Figure 2 As shown, it includes multiple air inlet baffles, which are petal-shaped structures. The multiple air inlet baffles are arranged sequentially along the circumference to form a petal structure, so as to form a chamber capable of compressing air between the multiple air inlet baffles.

[0033] The air inlet baffle has a petal-like structure, meaning its cross-section is arc-shaped and gradually narrows from one end to the other; the end with the longer arc length is the wide end, and the other end is the narrow end. In this embodiment, the air inlet baffle resembles a lotus petal structure, and four baffles are provided. For ease of description, from left to right in the view direction, they are designated as the first air inlet baffle 1, the second air inlet baffle 5, the third air inlet baffle 4, and the fourth air inlet baffle 3.

[0034] Of course, in other embodiments, the structure and number of air intake baffles can be adapted.

[0035] This embodiment uses four air intake baffles as an example for detailed explanation:

[0036] like Figure 1 and Figure 2 As shown, the first air inlet baffle 1, the second air inlet baffle 5, the third air inlet baffle 4, and the fourth air inlet baffle 3 are arranged sequentially in a clockwise direction. Adjacent air inlet baffles are connected to each other. The wide ends of the four air inlet baffles form an air inlet, and the narrow ends form an air outlet 26 when the air inlet baffles are tightened. In order to allow the air inlet baffles to be relatively tightened or expanded, the air inlet baffles are rotatably connected and connected to baffle springs 9.

[0037] Each air inlet baffle is equipped with a traction component on its outer side. Each traction component is controlled by the same push component to achieve synchronous operation of each air inlet baffle.

[0038] In this embodiment, the pushing component includes a base plate 10 and a linear power source. The linear power source is fixedly connected to the base plate 10. The linear power source is located on one side of the base plate 10, and each air intake baffle and the pulling component are located on the other side of the base plate 10. The linear power source drives the base plate 10 to move towards the air intake grille side, causing each air intake baffle to gradually tighten. The linear power source also drives the base plate 10 to move away from the air intake grille side, causing each air intake baffle to gradually unfold.

[0039] A linear power source is a component capable of providing linear power, which can be a linear motor 13, an electric actuator, a cylinder, a hydraulic cylinder, or the like. In this embodiment, the linear power source is a linear motor 13, which is connected to a support head 11 via a connecting rod 12. The support head 11 is fixedly connected to the base plate 10.

[0040] The base plate 10 can be of any shape. In this embodiment, a circular base plate 10 is used for ease of installation and to save space.

[0041] The first air inlet baffle 1 corresponds to the first pulling assembly, the second air inlet baffle 5 corresponds to the second pulling assembly, the third air inlet baffle 4 corresponds to the third pulling assembly, and the fourth air inlet baffle 3 corresponds to the fourth pulling assembly; wherein, the first pulling assembly includes a first tightening seat 15, a first pulley 14, and a first pulley support 16, and the first tightening seat 15 is fixed to the outside of the first air inlet baffle 1; in this embodiment, the longitudinal section of the first tightening seat 15 is a right-angled triangle, one of the right-angled sides is fixed to the first air inlet baffle 1, and the surface of the first tightening seat 15 away from the first air inlet baffle 1 is an inclined surface, and the angle between the inclined surface and the vertical direction is an acute angle.

[0042] The inclined surface of the first tightening seat 15 is provided with a first pulley track 22, and the first pulley 14 can move along the first pulley track 22; Figure 1 With the view direction as a reference, the first pulley 14 is installed on the top of the first pulley support 16. The first pulley 14 moves with the first pulley support 16. When the first pulley 14 moves to the top of the first pulley track 22, the first air inlet baffle 1 is in a vertical state, that is, each air inlet baffle is in a tightened state.

[0043] The first pulley support 16 serves as a support component for the first pulley 14, with its bottom end fixedly connected to the base plate 10, thereby enabling movement under the action of the pushing assembly. The side of the first pulley support 16 facing the first tightening seat 15 is also an inclined surface, and this inclined surface is parallel to the inclined surface of the first tightening seat 15. To ensure the running trajectory of the first pulley 14, a first fixing seat 17 is provided on the outer side of the first pulley support 16. The surface of the first fixing seat 17 facing the first pulley support 16 is set as an inclined surface, and the first pulley support 16 contacts this inclined surface, thereby creating a holding force on the first pulley support 16 from the first fixing seat 17, pushing the first tightening seat 15 and the first air inlet baffle 1 inward to a vertical position.

[0044] Similarly, the second traction assembly includes a second tightening seat 18, a second pulley 20, a second pulley support 19, and a second fixed seat, with the second tightening seat 18 having a second pulley track 23; the third traction assembly includes a third tightening seat 2, a third pulley 6, a third pulley support 7, and a third fixed seat 8, with the third tightening seat 2 having a third pulley track 21; the fourth traction assembly includes a fourth tightening seat 24, a fourth pulley, a fourth pulley support 25, and a fourth fixed seat, with the fourth tightening seat 24 having a fourth pulley track.

[0045] like Figure 2 As shown, the first tightening seat 15, the second tightening seat 18, the third tightening seat 2 and the fourth tightening seat 24 are arranged in a cross shape and are evenly distributed on the base plate 10.

[0046] The variable intake temperature grille system of this embodiment also includes a temperature sensor and a controller. The temperature sensor and the pushing component are both connected to the controller. The temperature sensor is used to detect the outside temperature. The controller is used to control the pushing component to push the intake damper to a tightened state when the outside temperature is higher than a set threshold, and to control the intake damper to expand to a set angle when the outside temperature is lower than the set threshold.

[0047] In this embodiment, each air inlet baffle can be either tightened or expanded to a corresponding angle. Specifically, the working principle is as follows:

[0048] A temperature threshold is preset, for example, set to 40℃. When the ambient temperature exceeds 40℃, the cooling mode is activated. A cooling signal is sent to the controller via a temperature sensor. The controller controls the pushing component to move the base plate 10 forward (towards the side facing the air intake grille). Simultaneously, the air intake baffles connected to the base plate 10 move as follows:

[0049] The first pulley support 16 pushes the first pulley 14 to move upward along the first pulley track 22. During the movement, the first fixed seat 17 forms a position-holding tension on the first pulley support 16 to ensure that the running trajectory remains vertically upward, pushing the first tightening seat 15 and the first air inlet baffle 1 to converge inward to a vertical position.

[0050] At the same time, the second pulley support 19 pushes the second pulley 20 to move upward along the second pulley track 23. During the movement, the second fixed seat forms a pulling force on the second pulley support 19 to maintain its position, pushing the second tightening seat 18 and the second air inlet baffle 5 to converge inward to a vertical position.

[0051] The third pulley support 7 pushes the third pulley 6 to move upward along the third pulley track 21. During the movement, the third fixed seat 8 forms a pulling force on the third pulley support 7 to maintain its position, pushing the third tightening seat 2 and the third air inlet baffle 4 to converge inward to a vertical position.

[0052] The fourth pulley support 25 pushes the fourth pulley to move upward along the fourth pulley track. During the movement, the fourth fixed seat forms a pulling force on the fourth pulley support 25 to maintain its position, pushing the fourth tightening seat 24 and the fourth air inlet baffle 3 to converge inward to a vertical position.

[0053] When the ambient temperature is below 40℃, the system returns to normal operating mode. A normal operating signal is sent to the controller via a temperature sensor, and the controller controls the push component to retract the base plate 10 back to its original position. The first pulley support 16 pulls the first pulley 14 downwards along the first pulley track 22. During this movement, the first fixed seat 17 also exerts a holding force on the first pulley support 16 to ensure the running trajectory remains vertically downwards. The first tightening seat 15 and the first air inlet baffle 1 unfold outwards at a certain angle (e.g., 30°) under the elastic force of the baffle spring 9, achieving the unfolding effect.

[0054] At the same time, the second pulley support 19 pushes the second pulley 20 to run downward along the second pulley track 23. During the movement, the second fixed seat forms a pulling force on the second pulley support 19 to maintain its position, ensuring that the running trajectory remains vertically downward; and pushes the second tightening seat 18 and the second air inlet baffle 5 to unfold outward at a certain angle under the elastic force of the baffle spring 9.

[0055] The third pulley support 7 pushes the third pulley 6 to run downward along the third pulley track 21. During the movement, the third fixed seat 8 forms a pulling force on the third pulley support 7 to maintain its position, ensuring that the running trajectory remains vertically downward. The third tightening seat 2 and the third air inlet baffle 4 are pushed to unfold outward at a certain angle under the elastic force of the baffle spring 9.

[0056] The fourth pulley support 25 pushes the fourth pulley to run downward along the fourth pulley track. During the movement, the fourth fixed seat forms a pulling force on the fourth pulley support 25 to maintain its position, ensuring that the running trajectory remains vertically downward. The fourth tightening seat 24 and the fourth air inlet baffle 3 are pushed to unfold outward at a certain angle under the elastic force of the baffle spring 9.

[0057] This embodiment monitors the ambient temperature using a temperature sensor and automatically controls the push components to tighten or expand the air intake baffles. When cooling is needed, the air intake baffles retract to a vertical position, forming air outlets 26. This compresses the intake air temperature to the head contraction opening (air outlet 26), achieving a reduction in intake air temperature. This improves vehicle cooling efficiency without increasing the electrical load, solving the problem of high-load operation of the vehicle's cooling system due to excessively high intake air temperature. Simultaneously, by reducing the intake air temperature, it assists in vehicle cooling, reducing heat loss of electrical components and shortening their lifespan due to high-load operation.

[0058] Example 2:

[0059] This embodiment provides a vehicle equipped with the variable intake air temperature grille system described in Embodiment 1. The system is installed inside the intake grille, wherein the air intake formed by the air intake baffle faces the intake grille, and the air outlet faces the engine and other internal structures.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
