[0013] As a further implementation method, the surfaces of the tightening seat and the pulley support that are close to each other are inclined surfaces, and the pulley track is at a set angle relative to the air inlet baffle.

[0014] As a further implementation, a fixing seat is provided on a side of the pulley support away from the tightening seat, and the fixing seat is used to form a pulling force on the pulley support to maintain its position.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] Embodiment 1:

[0032] This embodiment provides a variable air intake temperature grille system, which uses bionic design to set air intake baffles arranged in a petal-like manner inside the air intake grille, and uses the principle of compressed air to achieve autonomous control of the air intake temperature; Figure 1 and Figure 2 As shown, it includes multiple air inlet baffles, each of which is a petal-shaped structure. The multiple air inlet baffles are arranged in sequence along the circumferential direction 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 is a petal-shaped structure, which means that its cross section is arc-shaped and gradually narrows from one end to the other end; the end with a longer arc length of the air inlet baffle is the wide end, and the other end is the narrow end. In this embodiment, the air inlet baffle is similar to the structure of lotus petals, and four are provided. For the convenience of description, from the left to the right in the viewing direction, they are 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 the air inlet baffles can be adaptively adjusted.

[0035] This embodiment takes four air inlet baffles as an example for detailed description:

[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 in sequence in the clockwise direction, and the adjacent air inlet baffles are connected to each other. The wide ends of the four air inlet baffles enclose 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 unfolded, the air inlet baffles are rotatably connected to each other and connected to the baffle spring 9.

[0037] A pulling assembly is installed on the outer side of each air inlet baffle, and each pulling assembly is controlled by the same pushing assembly to achieve synchronous movement of each air inlet baffle.

[0038] In this embodiment, the pushing component includes a base plate 10 and a linear power source, which is fixedly connected to the base plate 10, wherein the linear power source is arranged on one side of the base plate 10, and each air inlet baffle and the pulling component are arranged on the other side of the base plate 10. The linear power source drives the base plate 10 to move toward the air inlet grille side, so that each air inlet baffle is gradually tightened; the linear power source drives the base plate 10 to move away from the air inlet grille side, so that each air inlet baffle is gradually expanded.

[0039] The linear power source is a component that can provide linear power, which can be a linear motor 13, an electric push rod, a cylinder, a hydraulic cylinder, etc. In this embodiment, the linear power source adopts a linear motor 13, and the linear motor 13 is connected to the support head 11 through a connecting rod 12, and the support head 11 is fixedly connected to the base plate 10.

[0040] The base plate 10 can be in any shape. In order to facilitate installation and save space, the present embodiment adopts a circular base plate 10.

[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 outer side of the first air inlet baffle 1; in this embodiment, the longitudinal cross-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 on one side 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 Taking the viewing direction as a reference, the first pulley 14 is installed at the top of the first pulley support 16, and 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 supporting component for the first pulley 14, and its bottom end is fixedly connected to the base plate 10, so that it can move under the action of the pushing component. The side of the first pulley support 16 facing the first tightening seat 15 is also an inclined surface, and the inclined surface is parallel to the inclined surface of the first tightening seat 15. In order to ensure the running track of the first pulley 14, a first fixed seat 17 is arranged on the outer side of the first pulley support 16, and the side surface of the first fixed seat 17 facing the first pulley support 16 is arranged as an inclined surface, and the first pulley support 16 contacts the inclined surface, so that the first fixed seat 17 forms a pulling force to maintain the position of the first pulley support 16, pushing the first tightening seat 15 and the first air inlet baffle 1 to gather inward to a vertical position.

[0044] Similarly, the second pulling assembly includes a second tightening seat 18, a second pulley 20, a second pulley support 19, and a second fixed seat, and the second tightening seat 18 is provided with a second pulley track 23; the third pulling assembly includes a third tightening seat 2, a third pulley 6, a third pulley support 7, and a third fixed seat 8, and the third tightening seat 2 is provided with a third pulley track 21; the fourth pulling assembly includes a fourth tightening seat 24, a fourth pulley, a fourth pulley support 25, and a fourth fixed seat, and the fourth tightening seat 24 is provided with 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 air 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 external temperature. The controller is used to control the pushing component to push the air inlet baffle to a tightened state when the external temperature is higher than a set threshold. When the external temperature is lower than a set threshold, the controller controls the air inlet baffle to expand to a set angle.

[0047] Each air inlet baffle of this embodiment can be in a tightened state or can be expanded to a corresponding angle. Specifically, the working principle is:

[0048] A temperature threshold is preset, for example, the temperature threshold is set to 40°C; when the ambient temperature exceeds 40°C, the cooling working mode is started, and a cooling working signal is sent to the controller through the temperature sensor. The controller controls the pushing component to drive the base plate 10 to move forward (with the side moving toward the air intake grille as the front), and the air intake baffles connected to the base plate 10 move simultaneously, 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 pulling force to maintain the position of the first pulley support 16, ensuring that the running track remains vertically upward, pushing the first tightening seat 15 and the first air inlet baffle 1 inward to gather 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 to maintain the position of the second pulley support 19, pushing the second tightening seat 18 and the second air inlet baffle 5 to gather 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 to maintain the position on the third pulley support 7, pushing the third tightening seat 2 and the third air inlet baffle 4 to gather 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 to maintain the position of the fourth pulley support 25, pushing the fourth tightening seat 24 and the fourth air inlet baffle 3 to gather inward to a vertical position.

[0053] When the outside temperature is lower than 40°C, the normal temperature working mode is restored; the normal temperature working signal is sent to the controller through the temperature sensor, and the controller controls the pushing component to drive the base plate 10 to retract to the return position; wherein, the first pulley support 16 pulls the first pulley 14 to move downward along the first pulley track 22, and during the movement, the first fixed seat 17 also forms a pulling force to maintain the position of the first pulley support 16 to ensure that the running track remains vertically downward. Under the elastic force of the baffle spring 9, the first tightening seat 15 and the first air inlet baffle 1 are expanded outward at a certain angle (for example, 30°) to achieve the expansion effect.

[0054] At the same time, the second pulley support 19 pushes the second pulley 20 to move downward along the second pulley track 23. During the movement, the second fixed seat forms a pulling force to maintain the position of the second pulley support 19, ensuring that the running trajectory remains vertically downward; the second tightening seat 18 and the second air inlet baffle 5 are pushed 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 move downward along the third pulley track 21. During the movement, the third fixed seat 8 forms a pulling force to maintain the position of the third pulley support 7, ensuring that the running trajectory remains vertically downward; the third tightening seat 2 and the third air inlet baffle 4 are pushed 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 move downward along the fourth pulley track. During the movement, the fourth fixed seat forms a pulling force to maintain the position of the fourth pulley support 25, ensuring that the running trajectory remains vertically downward; the fourth tightening seat 24 and the fourth air inlet baffle 3 are pushed outward at a certain angle under the elastic force of the baffle spring 9.

[0057] This embodiment monitors the outside temperature through a temperature sensor and automatically controls the push assembly to achieve the tightening or unfolding of each air inlet baffle; when cooling is required, each air inlet baffle shrinks to a vertical state to form an air outlet 26, so that the intake air temperature will be compressed to the position of the head contraction port (air outlet 26), achieving the effect of reducing the intake air temperature; thereby, the heat dissipation efficiency of the vehicle can be improved without increasing the load of electrical functions, solving the problem of high-load operation of the vehicle heat dissipation system due to excessively high intake air temperature. At the same time, by reducing the intake air temperature, the heat dissipation of the vehicle is assisted, and the heat loss of electrical components and the shortened life due to high-load operation are reduced.

[0058] Embodiment 2:

[0059] This embodiment provides a vehicle equipped with the variable air intake temperature grille system described in Embodiment 1, wherein the system is installed on the inner side of the air intake grille, wherein the air inlet formed by the air inlet baffle faces the air intake grille, and the air outlet faces the internal structure such as the engine.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
