[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] like Figure 1-Figure 8As shown, the embodiment of the present application provides an autonomously opening and closing automobile grille, which is a component of the automobile and is preferably used for air intake regulation of the cooling system of the automobile engine. The engine of the automobile is arranged in the engine compartment of the automobile, and air flow is formed in the engine compartment, so that the engine in the engine compartment can be cooled. The air intake grille at the front of the vehicle body constitutes an air intake port of the engine compartment air flow channel, and an active grille is also arranged between the air intake grille and the engine. The active grille can adjust the opening angle under the drive of a driving device, so as to achieve the regulation of the air flow. However, this kind of heat dissipation system has certain defects in practice. On the one hand, the air flow passes through the air grille and the active grille twice, and the air flow effect is poor. Moreover, the active grille also needs to be provided with a power drive device, and the coordination of each component is complicated. Moreover, the space in the automobile engine compartment is relatively small, which is not conducive to the overall space layout design. The autonomously opening and closing automobile grille provided by the present application aims to achieve structural simplification and improve the smoothness of air flow during engine cooling.

[0031] The self-opening and closing automobile grille provided in the embodiment of the present application includes a grille body 100, which is arranged in a plate shape. The grille body 100 is used to be arranged at the air inlet of the vehicle body cabin, that is, the grille body 100 is used to replace the front air intake grille on the traditional vehicle. The grille body 100 is provided with an airflow window 600. The grille body 100 is a flat plate structure. The airflow window 600 penetrates the grille body 100 along the thickness direction of the grille body 100. The airflow window 600 allows air to pass through. It also includes a barrier sheet 200. The barrier sheet 200 is a sheet structure. The barrier sheet 200 is connected to the grille body 100. The barrier sheet 200 can open or close the airflow window 600. When the barrier sheet 200 opens the airflow window When the opening 600 is closed, the airflow is prevented from entering the vehicle's cabin. When the baffle plate 200 opens the airflow window 600, the airflow can flow smoothly into the cabin to cool the engine 500. In this embodiment, the baffle plate 200 is made of a memory material with a two-way shape memory effect. Under different temperature conditions, the shape of the baffle plate 200 can change, thereby realizing the opening or closing of the airflow window 600. In this way, there is no need to set an active grille in the cabin, and the airflow can be adjusted by relying solely on the grille body 100. The overall structure is simple, with fewer components, which is conducive to the overall layout of the space. Moreover, the airflow only impacts once at the grille body 100, making the airflow flow smoother.

[0032] In this embodiment, the material of the barrier piece 200 is preferably a memory alloy with a two-way shape memory effect. The memory alloy material is trained to have a two-way shape memory effect. For example, it can be a nickel-titanium alloy, a copper-based memory alloy, or an iron-based memory alloy. The material of the barrier piece 200 is preferably a nickel-titanium memory alloy.

[0033] In some embodiments, the number of airflow windows 600 is multiple, and the multiple airflow windows 600 are evenly distributed on the grille body 100, which is conducive to the uniform inflow of airflow. The airflow windows 600 are arranged in a long strip shape, and each airflow window 600 is arranged side by side in sequence. The lengths of each airflow window 600 can be the same or different. The directions of each airflow window 600 are parallel to each other, and the arrangement direction of each airflow window 600 is perpendicular to the length direction of the airflow window 600. In this embodiment, the number of the barrier sheet 200 and the number of the airflow windows 600 are equal. In the same manner, each barrier sheet 200 corresponds to an airflow window 600, that is, one airflow window 600 corresponds to one barrier sheet 200, one side of the barrier sheet 200 is connected to the grille body 100, the airflow window 600 is a window with a rectangular cross-section, the barrier sheet 200 is in the shape of a rectangular long plate, and the bottom side of the barrier sheet 200 is connected to the bottom side of the airflow window 600 on the grille body 100, so that the barrier sheet 200 blocks the airflow window 600. In this embodiment, in an environment below 40 degrees Celsius, the shape of the barrier sheet 200 is a long strip plate, such as Figure 4 As shown, the barrier sheet 200 can close the airflow window 600. As the engine 500 runs and dissipates heat, the temperature in the cabin gradually rises. When the temperature in the cabin exceeds 40 degrees Celsius, the barrier sheet 200 is partially bent in the middle due to the effect of the memory alloy material. Preferably, the barrier sheet 200 is deformed in an arc shape, so that the barrier sheet 200 changes from a plate shape to an arc shape. Figure 5 As shown, in the cross section perpendicular to the length direction of the baffle plate 200, the cross section of the baffle plate 200 becomes an arc. Preferably, the bottom side of the baffle plate 200 is connected to the grille body 100, and the top side of the baffle plate 200 is bent toward one side of the grille body 100. The top side of the baffle plate 200 is bent in an arc shape toward the interior of the cabin. In this way, the airflow window 600 can be opened to achieve smooth entry of airflow to cool the engine 500. When the cabin temperature is lower than 40 degrees Celsius, the baffle plate 200 is deformed into a long plate shape, and then the airflow window 600 is closed. In this way, the opening or closing of the airflow window 600 on the grille body 100 is adjusted according to the temperature change. In this embodiment, at 40 degrees Celsius, the baffle plate 200 is flat.

[0034] Preferably, a connecting groove 101 is provided on the grille body 100 at the position of the airflow window 600, and one side of the barrier piece 200 is inserted into the connecting groove 101. In this embodiment, the airflow window 600 is opened on the grille body 100 along the horizontal direction, and a connecting groove 101 is provided on the grille body 100 at a position corresponding to the bottom side of the airflow window 600, and the barrier piece 200 can be inserted into the connecting groove 101. In addition, the connection can be strengthened by adhesives and the like to improve the connection strength. In this embodiment, one side of the barrier piece 200 is inserted into the connecting groove 101, and the other side of the barrier piece 200 can swing with the change of temperature, thereby realizing the adjustment of the opening or closing of the airflow window 600. In this embodiment, the material of the grille body 100 can be plastic.

[0035] More preferably, a retaining edge 102 is provided on the grille body 100 at the position of the airflow window 600 and on the side facing the airflow flow, and the retaining edge 102 and the connecting groove 101 are respectively located on opposite sides of the airflow window 600. When the blocking piece 200 closes the airflow window 600, the swinging side of the blocking piece 200 abuts against the retaining edge 102. In this embodiment, for the airflow window 600, the retaining edge 102 is provided on the top side of the airflow window 600, and the connecting groove 101 is provided on the airflow window 600. 0, the bottom of the barrier sheet 200 is inserted into the connecting groove 101. In an environment below 40 degrees Celsius, the barrier sheet 200 is flat, and the top outer side of the barrier sheet 200 abuts against the retaining edge 102. When the temperature exceeds 40 degrees Celsius, the top of the barrier sheet 200 bends in an arc shape toward the inside, so that the top of the barrier sheet 200 leaves the retaining edge 102, thereby opening the airflow window 600. The setting of the retaining edge 102 can not only improve the sealing effect, but also play a positioning role.

[0036] In a preferred embodiment, the barrier sheet 200 includes a first section 201 and a second section 202. One side of the first section 201 is connected to the grille body 100, and the other side of the first section 201 is connected to one side of the second section 202. When the first section 201 and the second section 202 are deformed, the other side of the second section 202 can swing around the connection position between the first section 201 and the grille body 100. In this embodiment, in an environment below 40 degrees Celsius, the barrier sheet 200 is a long flat plate as a whole. The barrier sheet 200 is horizontally placed, the first section 201 is the lower part of the barrier sheet 200, the second section 202 is the upper part of the barrier sheet 200, the first section 201 and the second section 202 are both long flat plate structures, the bottom of the first section 201 is inserted into the connecting groove 101, the top of the first section 201 and the bottom of the second section 202 are connected, the top of the second section 202 is against one side of the retaining edge 102, and the first section 201 and the second section 202 cooperate to block the airflow window 600, as shown in FIG. Figure 6As shown, the first section 201 and the second section 202 are both memory alloys with a two-way shape memory effect. The first section 201 and the second section 202 have different transformation temperatures. For example, when the temperature exceeds 40 degrees Celsius, the second section 202 deforms in an arc shape, while the first section 201 does not deform. Figure 7 As shown in FIG. 1 , the top of the second section 202 is curved in an arc shape in a direction away from the baffle 102, and the airflow window 600 is opened to a certain area. When the temperature in the cabin exceeds 65 degrees Celsius, the first section 201 is deformed, and the top of the first section 201 is also curved in an arc shape in a direction away from the baffle 102. In addition, the second section 202 has already been curved in an arc shape. Figure 8 As shown, at this time, the area of ​​the airflow window 600 opened is larger, so that as the temperature rises, the area of ​​the open airflow window 600 can be adjusted, which makes airflow adjustment more convenient.

[0037] In this embodiment, after the first section 201 and the second section 202 are both deformed into an arc shape, the arc deformation angle of the first section 201 and the arc deformation angle of the second section 202 may be the same.

[0038] The present application also provides a cooling device for an engine 500, such as Fig. 9 As shown, the above-mentioned autonomously opened and closed automobile grille also includes an air flow channel 300, a cooling module 400 and an engine 500. The cabin space of the vehicle constitutes the air flow channel 300. The grille body 100, the cooling module 400 and the engine 500 are arranged in sequence along the direction of air flow in the air flow channel 300. The front end of the air flow channel 300 is the grille body 100, followed by the cooling module 400. The cooling module 400 can cool the air flow, and the cooled air flow flows to the engine 500, thereby cooling the engine 500. The air flow can enter the air flow channel 300 through the air flow window 600 opened on the grille body 100. In this embodiment, compared with the traditional engine 500 cooling system, the setting of the complex active grille is omitted, and the overall structure of the grille body 100 and the barrier plate 200 is simpler. Moreover, under the action of the memory material, the adjustment of the air flow can be more convenient. Compared with the double-layer grille structure of the transmission, the single-layer grille body 100 only produces one impact on the air flow, which is conducive to the smooth flow of the air flow.
