Description

[0002] The range-extending or plug-in hybrid vehicle still needs an engine to participate in the driving condition, and the air inlet grille needs to be used to adjust the air inlet. The active air inlet grille is mainly used in high-end vehicles, the opening and closing of the air inlet grille is controlled to change the air inlet effect, so that the engine temperature is maintained in the case of low-temperature cold start to improve the operation efficiency. Some high-performance new energy vehicles also design the air inlet grille to assist in cooling the battery or motor assembly of the vehicle. For example, the existing technology with the announcement number CN217672529U discloses a high-strength active air inlet grille, which comprises an air inlet grille main body, an external protective cover and a filter screen. The external protective cover is sleeved on the outer side of the air inlet grille main body, and the filter screen is arranged on the inner side of the external protective cover. A connecting seat integrally arranged on the external protective cover is movably inserted into a mounting seat through the filter screen. One end of a connecting plate fixedly connected with a buffer spring arranged in the mounting seat abuts against the connecting seat. A connecting screw penetratingly arranged in the connecting seat is threadedly connected with the connecting plate.

[0003] The above-mentioned existing technology adds a screen in the active air inlet grille to avoid the impact of mosquitoes and the like on the surface of the cooling mechanism or the air inlet grille. Although the screen has good protection effect, the screen will significantly reduce the air inlet efficiency. In addition, the screen lacks a cleaning scheme, and the screen will further affect the cooling of the engine or the battery motor and the normal operation of the new energy vehicle after being blocked.

[0004] For example, the prior art, patent number CN220947540U, describes a self-cleaning active air intake grille, relating to the technical field of automotive design and manufacturing. This self-cleaning active air intake grille includes an active air intake grille body, a filter, and a scraper mechanism. The active air intake grille body includes an air intake grille frame, grille blades, and a blade motor; the grille blades are connected by a first fixing mechanism; the grille blades pass through a first slot and are connected to the output shaft of the blade motor; the scraper mechanism includes a scraper arm, an elastic scraper blade, a rotating shaft, and a scraper motor; the scraper arm is mounted on the rotating shaft, which passes through a second slot and is connected to the scraper motor; the elastic scraper blade contacts the filter. This self-cleaning active air intake grille allows for convenient and timely cleaning of foreign objects from the air intake grille, preventing prolonged obstruction of the cooling system by foreign objects, improving cooling system performance, and extending service life.

[0005] While the aforementioned existing technologies include a cleaning mechanism for cleaning the screen, the use of motors and scraper arms leads to excessive encroachment on the vehicle's front compartment space, resulting in very high costs. Furthermore, the presence of the screen itself does not solve the problem of its impact on air intake performance. Summary of the Invention

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0035] Please refer to Figures 1-11 The present application provides the following technical solutions:

[0036] Embodiment one: The scheme disclosed in this embodiment is to solve the problems existing in the prior art, so that the active air inlet grille has the stone / mosquito protection function under specified conditions, and can completely open the air holes under specified conditions to ensure the air cooling air inlet amount. Specifically, as Figure 1 and Figure 2The shown includes a skeleton 1 for installing the decorative strip, the air hole formed between the adjacent two skeletons 1 is used for air flow through and cooling the engine related components, and the outer frame 2 for fixing the skeleton 1 in the vehicle, wherein the back of the skeleton 1 is covered with a wind board 3, which is opened or closed by active activity, and the filter element is arranged in the adjacent two skeletons 1, which is distributed close to the back of the skeleton 1 and used to cover the air hole, wherein the wind board 3 is movably installed in the outer frame 2, and by the initial state of the wind board 3, the filter element is deformed in the direction away from the back of the skeleton 1, and when the wind board 3 restores to the original state, it is used to guide the filter element to restore the coverage of the air hole, wherein the filter element is used to block the sundries from contacting the wind board 3, and the deformation of the filter element is used to discharge the filtered sundries, and in the normal state, the wind board 3 covers the air hole, and the mesh cloth 4 is also in the state of complete coverage, in this state, the insects and stones that may be generated by the air flow impact during the driving process of the started vehicle are blocked by the mesh cloth 4, so that the surface of the wind board 3 is effectively prevented from remaining too many insect corpses due to the closing of the grille, and after the wind board 3 is opened, which means that the engine components need more air intake, so the opening of the wind board 3 will simultaneously drag the mesh cloth 4 to completely open the air hole by deforming, so as to avoid affecting the air intake to cause the overheating of the engine related components, and when the vehicle stops or the grille is closed again, the mesh cloth 4 will again deform to restore the coverage of the air hole and the wind board 3, and in the process of opening and closing, the mesh cloth 4 will deform many times, and will deform towards the outside, so that the deformation will cause the stones or insect corpses remaining on the surface of the mesh cloth 4 to fall off towards the outside, even if the falling off during driving will cause the remaining to move towards the inside of the vehicle due to the wind force, but will avoid directly impacting on the radiator due to the initial blocking and deceleration effect of the mesh cloth 4 and directly fall from the bottom of the vehicle, so as to avoid the blocking of the mesh cloth 4 caused by the accumulation of insects and stones and realize the automatic auxiliary cleaning.

[0037] In this embodiment, the above scheme is further refined, which can also be regarded as another embodiment, and the specific content is embodied in the association between the movement of the wind board 3 and the deformation of the mesh cloth 4, such as Figures 3-8The shown scheme, the filter element is a mesh cloth 4, the mesh cloth 4 is a deformable material such as chemical fiber or metal or composite, one end of the filter element is fixed on the left side wall of a skeleton 1, and the other end is initially connected to the right side wall of another skeleton 1 adjacent to the left side of the above skeleton 1 through a pulling bar 5, wherein the pulling bar 5 is connected to the movable end of the wind plate 3 through a connecting piece, so that the wind plate 3 cooperates with the connecting piece and the pulling bar 5, and the movable wind plate 3 drives the deformation of the filter element, the connecting piece is a connecting rope 6 made of elastic material, wherein the connecting rope 6 is in a relaxed state before the wind plate 3 moves to the specified position, the left side wall of the pulling bar 5 is provided with a magnetic sheet 8, and the magnetic sheet 8 is also magnetically attracted to the magnetic sheet 8 installed on the right side wall of the skeleton 1, so that the rear section of the pulling bar 5 moves backward to accelerate, and the right side wall of the pulling bar 5 is provided with an elastic bar 7 between the right side wall of the skeleton 1, which is used to drive the pulling bar 5 to move backward synchronously by using the elastic potential energy of the bar 7 when the wind plate 3 moves backward, in the normal state, the wind plate 3 rotates around the longitudinal axis of the right end, and is driven to rotate actively by the motor and connecting rod structure integrated with the grille (for example, the active air intake grille driving mechanism in the high-end BMW models), and the left end of the wind plate 3 drives the pulling bar 5 to slide in the outer frame 2 along the direction perpendicular to the skeleton 1, that is, the rotation of the wind plate 3 drives the pulling bar 5 to guide the deformation or recovery of the mesh cloth 4 in the sliding process through the connecting rope 6, and the recovery process is driven by the elastic potential energy of the bar 7, and in this scheme, a certain margin is set for the overall length of the connecting rope 6, so that before the wind plate 3 is opened to a specified angle, the pulling bar 5 will be stably maintained in a certain state under the magnetic attraction of the magnetic sheet 8, and the air inlet and mosquito sand stone blocking can be realized synchronously, thereby increasing the use of the active air intake grille, and in the subsequent process of the wind plate 3 rotating and opening, after the wind plate 3 rotates to a specified angle but before the wind plate 3 is completely closed, the connecting rope 6 is in a relatively relaxed state, at this time the pulling bar 5 will quickly move backward under the magnetic attraction and produce a collision contact effect, thereby generating a vibration force to improve the cleaning efficiency of the mesh cloth 4 and produce an additional cleaning effect, in actual application, if the material characteristics of the connecting rope 6 are prone to fatigue failure, the wind plate 3 can also be quickly closed by the driving mechanism, and the same effect of the rapid backward movement of the pulling bar 5 can also be achieved.

[0038] In this embodiment, the main problem to be solved is another problem, that is, to provide a more efficient cleaning method for the filter element, and to achieve different effects according to the rotation angle adjustment of the wind plate 3, specifically as follows Figures 9-11As shown, the front surface of the wind plate 3 is also provided with a cleaning mechanism, which cleans the filter and the grille by blowing air or water flow. When the rotation angle of the wind plate 3 is greater than 90°, the fluid can also cool the engine assembly. The cleaning mechanism includes longitudinally or transversely distributed cleaning strips 10, the surface of which is provided with perforations 11 for spraying fluid. The internal cavity of the cleaning strip 10 is connected to a pipe body 9 installed on the back or top end of the wind plate 3. The input end of the pipe body 9 is connected to a vehicle-mounted fluid supply mechanism, which is an air pump or a water pump integrated with a water tank. Regardless of whether it is an air pump or a water pump, the generated fluid enters the cavity in the cleaning strip 10 through the pipe body 9 and is finally sprayed out through the perforations 11 or nozzles on the surface of the cleaning strip 10. When the perforations 11 are distributed facing the filter or the grille, the blown fluid is mainly for cleaning. When the supply mechanism is a water pump, the sprayed water acts on the air cooler in the engine assembly, which, in combination with the impact of the airflow during driving, can further improve the cooling effect. The distribution form of the pipe body 9 is determined according to the downstream manufacturer's customization requirements. When the pipe body 9 is installed on the back of the wind plate 3, its cost is lower, but the connection strength requirement of the pipe body 9 is higher. When installed on the top end of the wind plate 3, the vertical installation space requirement is higher, but the overall life of the pipe body 9 is longer and the weak impact of the pipe body 9 on the air intake effect is not caused.

[0039] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
