Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an active air intake grille for a new energy vehicle. Background Art

[0002] The extended-range or plug-in hybrid models in new energy vehicles still require the engine to participate in the driving conditions, and accordingly, the air intake grille needs to be used to adjust the air intake. The active air intake grille is mostly used in high-end models. The air intake effect is changed by controlling the opening and closing of the air intake grille, and then the engine temperature is maintained during cold start to improve operating efficiency. Some high-performance new energy models will also be designed with air intake grilles to assist in cooling the vehicle's battery or motor components. For example, a high-strength active air intake grille with announcement number CN217672529U in the prior art includes an air intake grille body, an external protective cover and a filter. The outer side of the air intake grille body is covered with an external protective cover, and the inner side of the external protective cover is provided with a filter. The connecting seat integrally arranged on the external protective cover is movably plugged into the mounting seat through the filter, and the connecting plate fixedly connected to one end of the buffer spring installed in the mounting seat abuts against the connecting seat, and the connecting screw set through the connecting seat is threadedly connected to the connecting plate. The external protective cover of this application can be directly installed on the front of the air intake grille body during use, effectively protecting the air intake grille body and effectively avoiding damage to the air intake grille body due to bumps and minor impacts during use. At the same time, the filter can effectively isolate impurities mixed in the intake air to prevent impurities from affecting the normal operation of the vehicle. The overall structure is simple and easy to use.

[0003] The above-mentioned existing technology prevents mosquitoes and the like from hitting the cooling mechanism or the air plate surface of the grille by adding a baffle in the active air intake grille. Although it has a good protective effect, the grille itself is used for air intake, and the presence of the baffle will significantly reduce the air intake efficiency. At the same time, the baffle itself lacks relevant cleaning solutions, and its blockage will further affect the cooling and even normal operation of the engine or battery motor in the new energy vehicle.

[0004] Another example is a self-cleaning active air intake grille with a publication number of CN220947540U in the prior art, which relates to the technical field of automobile design and manufacturing. The self-cleaning active air intake grille of this application includes an active air intake grille body, a filter screen, and a scraper mechanism; the active air intake grille body includes an air intake grille outer frame, grille blades, and a blade motor, and the grille blades are connected by a first fixing mechanism; the grille blades pass through a first hole slot and are connected to the output shaft of the blade motor; the scraper mechanism includes a scraper arm, an elastic scraper, a rotating shaft, and a scraper motor, the scraper arm is set on the rotating shaft, the rotating shaft passes through a second hole slot and is connected to the scraper motor, and the elastic scraper is in contact with the filter screen. The self-cleaning active air intake grille of this utility model can conveniently and promptly clean foreign matter from the air intake grille, prevent foreign matter from blocking the cooling system for a long time, improve the performance of the cooling system, and extend the service life.

[0005] Although a cleaning mechanism is designed in the above-mentioned prior art to clean the baffle, the use of structures such as motors and scraper arms will cause the front cabin space of the vehicle to be excessively occupied, and the economic cost is very high. At the same time, it also does not solve the problem that the existence of the baffle itself will affect the air intake effect. Summary of the Invention

[0006] The purpose of the present invention is to provide an active air intake grille for new energy vehicles to solve the problem in the above background technology that the conventional addition of a baffle will affect the air intake effect of the grille, while the use of a conventional cleaning mechanism will excessively occupy the vehicle's front cabin space and increase economic and maintenance costs.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an active air intake grille for a new energy vehicle, comprising a frame for mounting decorative strips, air holes formed between two adjacent frames for airflow to pass through and cool engine-related components, and an outer frame for fixing the frame in the vehicle, wherein the back of the frame is covered with an air plate, which opens or covers the air holes by active movement, and two adjacent frames are provided with filters distributed near their backs and used to cover the air holes, wherein the air plate is movably mounted in the outer frame, and through the self-movement of the air plate in the initial state, the filter is guided to deform in a direction away from the back of the frame, and when the air plate returns to its original state, it is used to guide the filter to resume covering the air holes, wherein the filter is used to prevent debris from contacting the air plate, and the deformation of the filter is used to discharge the filtered debris.

[0008] As a further solution, the filter element is a mesh, and the mesh is a deformable material such as chemical fiber, metal, or a composite.

[0009] As a further solution, one end of the filter element is fixed to the left side wall of a frame, and the other end is initially connected to the right side wall of another frame adjacent to the left side of the frame through a traction bar; As a further solution, the traction bar is connected to the movable end of the wind plate through a connecting piece, so the wind plate cooperates with the traction bar through the connecting piece and drives the filter element to deform through the movement of the wind plate.

[0010] As a further solution, the connecting member is a connecting rope made of elastic material, wherein the connecting rope is in a loose state before the wind plate moves to a specified position.

[0011] As a further solution, a magnetic sheet is installed on the left side wall of the traction bar, and the magnetic sheet is magnetically engaged with the magnetic sheet installed on the right side wall of the frame to accelerate the backward movement of the rear section of the traction bar.

[0012] As a further solution, an elastic bar is further provided between the right side wall of the traction bar and the right side frame thereof; As a further solution, the bar is used to utilize its own elastic potential energy to drive the traction bar to move back synchronously when the wind plate moves back.

[0013] As a further solution, a cleaning mechanism is also provided on the front of the wind plate, wherein the cleaning mechanism cleans the filter and the grille by blowing out air or water flow. When the rotation angle of the wind plate is greater than 90°, the fluid can also cool the engine components.

[0014] As a further solution, the cleaning mechanism includes cleaning strips distributed longitudinally or transversely, and the perforations opened on the surface of the cleaning strips are used to spray out the fluid.

[0015] As a further solution, the inner cavity of the cleaning strip is connected to a tube installed on the back or top of the wind plate, wherein the input end of the tube is connected to the vehicle-mounted fluid supply mechanism.

[0016] Compared with the existing technology, the beneficial effects of the present invention are: the active air intake grille of the new energy vehicle adopts a method of combining mesh and wind plate movement, which is compatible with the blocking protection of the wind plate and the vehicle, as well as the guarantee of the grille's own air intake and the cleaning of the mesh itself. There is no need to add an additional electric drive mechanism. The design is reasonable and more energy-saving and environmentally friendly, and is suitable for new energy vehicles. The details are shown below.

[0017] 1. The use of the wind plate and the traction bar enables the wind plate to move through the connecting rope when it is driven by the driving mechanism, thereby causing the mesh covering the air holes in the initial state to deform synchronously and maximize the grille air intake effect. At the same time, the deformation of the mesh itself can help prevent mosquitoes and sand and gravel from remaining in the mesh, thereby achieving an automatic cleaning effect; As further, the connecting rope leaves a certain amount of scheme design, cooperate with the magnetic sheet magnetic attraction effect of the surface of the traction strip, on the one hand, can be realized by controlling the wind plate rotation angle of the way to open the wind plate but the screen cloth does not move the protective type of air intake effect, on the other hand, can be realized by controlling the wind plate rotation speed or angle of the way, the screen cloth follow the rebound of the traction strip to produce the vibration effect of accelerated collision, and further improve the cleaning effect.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-11 , the present invention provides the following technical solutions: Embodiment 1: The solution disclosed in this embodiment is to solve the problems existing in the prior art, so that the active air intake grille has the stone / mosquito protection function under specified conditions, and can fully open the air holes under specified conditions to ensure the air cooling air intake. Figure 1 and Figure 2 The vehicle shown includes a frame 1 for installing decorative strips, air holes formed between two adjacent frames 1 for air flow to pass through and cool down engine-related components, and an outer frame 2 for fixing the frame 1 in the vehicle, wherein the back of the frame 1 is covered with an air plate 3, and the air plate 3 opens or covers the air hole by active movement. The two adjacent frames 1 are provided with filters distributed near their backs and used to cover the air hole, wherein the air plate 3 is movably installed in the outer frame 2, and through the self-movement of the air plate 3 in the initial state, the filter is guided to deform in a direction away from the back of the frame 1, and when the air plate 3 returns to its original shape, it is used to guide the filter to resume covering the air hole, wherein the filter is used to prevent debris from contacting the air plate 3, and the deformation of the filter is used to discharge the filtered debris. Under normal conditions, the air plate 3 covers the air hole, and the mesh 4 is also in a completely covered state. In this state, when the started car is driving, the mosquitoes and stones that may be generated by the impact of the air flow will be blocked by the mesh 4. When the grille is closed again, the mesh 4 will be deformed again to restore the coverage of the air holes and the wind plate 3. In the process of opening and closing, the mesh 4 will be deformed many times, and the deformation will be toward the outside. Therefore, the deformation will cause the stones or mosquito corpses remaining on the surface of the mesh 4 to fall toward the outside. Even if the falling off during driving will cause the residue to move toward the inside of the vehicle due to the wind force, it will be avoided from directly hitting the radiator due to the initial blocking and deceleration effect of the mesh 4, but will fall directly from under the vehicle, thus avoiding the accumulation of mosquitoes and stones to cause the mesh 4 to be blocked and realizing automatic auxiliary cleaning.

[0023] Embodiment 2: In this embodiment, the above solution is further refined and can also be regarded as another embodiment. The specific content is reflected in the relationship between the movement of the wind plate 3 and the deformation of the mesh 4, such as Figure 3-Figure 8 In the scheme shown, the filter element is a mesh 4, which is a deformable material such as chemical fiber, metal or composite. One end of the filter element is fixed to the left side wall of a frame 1, and the other end is initially connected to the right side wall of another frame 1 adjacent to the left side of the above-mentioned frame 1 through a traction strip 5, wherein the traction strip 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 traction strip 5 through the connecting piece, and the filter element is deformed by the movement of the wind plate 3. 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, and the left side of the traction strip 5 is connected to the movable end of the wind plate 3. A magnetic sheet 8 is installed on the side wall, and the magnetic sheet 8 is also magnetically matched with the magnetic sheet 8 installed on the right side wall of the frame 1, so that the rear section of the traction bar 5 is accelerated. An elastic bar 7 is also provided between the right side wall of the traction bar 5 and the frame 1 on its right side. The bar 7 is used to use its own elastic potential energy to drive the traction bar 5 to move back synchronously when the wind plate 3 moves back. Under normal conditions, the wind plate 3 rotates around the longitudinal axis of its right end, and the motor and connecting rod structure installed in the grille are used to drive the wind plate 3 to rotate actively (such as the active air intake grille drive mechanism in BMW high-end models), and the left end of the wind plate 3 The connecting rope 6 drives the traction bar 5 to slide in the outer frame 2 and along the direction perpendicular to the skeleton 1. That is to say, the rotation of the wind plate 3 will drive the traction bar 5 to guide the mesh 4 to deform or restore its deformation during the sliding process through the connecting rope 6. The process of restoring the deformation is driven by the elastic potential energy of the bar 7. At the same time, in this solution, a certain margin is set for the overall length of the connecting rope 6. In this way, before the wind plate 3 is rotated and opened to a specified angle, the traction bar 5 will stably maintain a given state under the magnetic attraction of the magnetic sheet 8, which can simultaneously achieve wind intake and mosquito and sand stone blocking, increasing the efficiency of the active air intake. The purpose of the air grille, and during the complete rotation and subsequent rotation of the wind plate 3, after it rotates to the specified angle but the wind plate 3 is not completely closed, the connecting rope 6 is already in a relatively loose state. At this time, the traction bar 5 will quickly move back under the action of magnetic attraction and produce a collision contact effect, thereby generating a vibration force to improve the cleaning efficiency of the mesh 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 driving mechanism can also be used to drive the wind plate 3 to close quickly, which can also produce the rapid return effect of the traction bar 5.

[0024] Embodiment 3: In this embodiment, another problem is solved, which is to provide a more efficient way to clean the filter element, and to achieve different effects according to the angle adjustment of the wind plate 3. Figures 9-11As shown, a cleaning mechanism is also provided on the front of the wind plate 3, wherein the cleaning mechanism cleans the filter and the grille by blowing out air or water flow. When the rotation angle of the wind plate 3 is greater than 90°, the fluid can also cool the engine components. The cleaning mechanism includes cleaning strips 10 distributed longitudinally or transversely, and the perforations 11 opened on the surface are used to spray the fluid. The internal cavity of the cleaning strip 10 is connected to the tube body 9 installed on the back or top of the wind plate 3, wherein the input end of the tube body 9 is connected to the vehicle-mounted fluid supply mechanism, which is an air pump or a water pump with an integrated water tank. Regardless of whether it is an air pump or a water pump, the fluid generated will enter the cavity in the cleaning strip 10 through the tube body 9, and finally pass through The perforations 11 or nozzles arranged on its surface spray out. When the perforations 11 are distributed facing the filter element or the grille, the fluid blown out is mainly used to provide cleaning. When the supply mechanism is a water pump, the sprayed water acts on the air cooler in the engine assembly. Combined with the impact airflow during driving, it can further improve the cooling effect. The distribution form of the tube body 9 is determined by the customization requirements of the downstream manufacturers. When the tube body 9 is installed on the back of the wind plate 3, its cost is lower, but the connection strength of the tube body 9 is higher. When installed on the top of the wind plate 3, higher requirements are required for the vertical installation space, but the overall life of the tube body 9 is longer and the existence of the tube body 9 will not cause a slight impact on the air intake effect.

[0025] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
