Abstract
Description
Technical Field
[0001] This utility model belongs to the field of air intake grille technology, and specifically relates to an air intake grille system. Background Technology
[0002] The car's air intake grille, also known as the front grille, primarily functions to allow air to enter and ventilate the radiator, engine, and air conditioning system, while preventing damage to internal components from foreign objects during driving. The design of the air intake grille directly impacts vehicle performance. Aerodynamic drag exists during vehicle movement; the design of the air intake and grille affects both the frontal area of the car and the overall airflow. A balance between the internal and external airflow fields should be achieved to minimize aerodynamic drag. Cooling performance and airflow volume must also be considered; the intake area should equal the radiator's frontal area, and the airflow volume must meet the engine's intake and cooling requirements.
[0003] The opening and closing of the blades in a car's air intake grille is crucial. Currently, the opening and closing of existing air intake grille blades are mainly controlled by motors. The blades cannot self-lock when open or closed, and they rely entirely on motor control, which greatly reduces the lifespan of the motor.
[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an air intake grille system.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this utility model is to provide an air intake grille system that can solve the problem that existing air intake grilles cannot self-lock.
[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: an air intake grille system, including an air intake grille and a control module thereon, wherein the air intake grille includes: an outer frame, multiple grille plates, a grille control component, and a self-locking mechanism.
[0008] The outer frame contains a pair of grille mounting areas and a control area located between them. Multiple grille panels are mounted within the pair of grille mounting areas, and rotating heads are fixed to both ends of each mounting area. A grille control assembly is mounted within the control area and fixedly connected to one end of the rotating head located within the control area. The grille control assembly includes multiple control arms and control components. One end of each control arm is fixedly connected to a plurality of rotating heads, and the other end is movably mounted on the side wall of the control component. The control component slides within the control area.
[0009] The self-locking mechanism is installed inside the two side walls of the control area. The self-locking mechanism includes: multiple moving parts, a control rod, a control component, and multiple elastic elements. A plug is fixed to one end of each moving part near the rotating head. A pair of slots adapted to the plug are carved on the rotating head. The control rod slides up and down on the two side walls of the control area and passes through the multiple moving parts. Arc-shaped grooves are carved on the control rod at each moving part. The multiple elastic elements are respectively installed at both ends of the upper end of the control rod and at the end of the moving part away from the plug.
[0010] In one embodiment of this utility model, the upper and lower ends of the grating plate are respectively chiseled with interlocking slots. The slots at the upper and lower ends of the grating plate respectively engage with the slots of the upper and lower grating plates. By the interlocking of the slots on the upper and lower grating plates, the sealing performance of the grating plate when closed is improved.
[0011] In one embodiment of this utility model, a plurality of control arms are equipped with second pulleys on the side away from the rotating head and on the same axis as the rotating head. Sliding grooves are carved on both sides of the control component, and the plurality of second pulleys slide in a pair of sliding grooves respectively. The control component slides on the plurality of second pulleys on both sides through a pair of sliding grooves on both sides, thereby realizing the sliding setting in the control area.
[0012] In one embodiment of this utility model, a lead screw is rotatably arranged in the control area. One end of the lead screw is connected to a driving device. The lead screw is threadedly connected to the control component. The drive device drives the lead screw to rotate, thereby causing the lead screw to move the control component up and down.
[0013] In one embodiment of this utility model, a first pulley is installed at the end of the control arm away from the rotating head, and multiple control grooves are vertically carved on both sides of the control component. The first pulley slides in the control groove, and the control component slides in the control groove through the first pulley, thereby realizing the movable connection between the control arm and the control component. Thus, when the control component moves up and down, the control component drives the rotating head to rotate through the control arm.
[0014] In one embodiment of this utility model, the control slot is a rectangle with both length and width greater than the diameter of the first pulley. When the control member drives the rotating head to rotate via the control arm, the first pulley moves in an arc with the rotating head as the axis. Therefore, the control slot is a rectangle with both length and width greater than the diameter of the first pulley to provide space for the first pulley to move upward when the control member drives the first pulley to move upward. In addition, the vertical width of the control slot is set to be greater than the diameter of the first pulley so that when the control member moves up and down, the plug is first moved out of the slot by the toothed plate and gear.
[0015] In one embodiment of this utility model, a third pulley is installed inside the movable component on one side of the arc-shaped groove. The third pulley slides on the arc-shaped groove, thereby reducing the friction between the movable component and the arc-shaped groove when the control rod pushes the movable component through the arc-shaped groove to pull the plug out of the slot.
[0016] In one embodiment of this utility model, the elastic element installed at the end of the plurality of movable parts away from the plug is a first spring. The elastic force of the first spring is used to push the movable parts towards the rotating head when there is no external force pushing them, so that the plug is inserted into the slot. The elastic elements installed at the upper and lower ends of the control rod are second springs. A pair of second springs are used to push the control rod when there is no external force pushing it, so that the control rod returns to its original position, that is, the third pulley is located at the innermost position of the arc of the arc groove.
[0017] In one embodiment of this utility model, the control component includes: a gear, a tooth groove, and a pair of toothed plates. The gear is mounted on the side wall of the control area. The tooth groove is carved into the side wall of the control rod near the gear and meshes with the gear. The pair of toothed plates are mounted on the two outer side walls of the control component and mesh with the gear. When the control component moves up and down, the toothed plates drive the gear to rotate, and the gear drives the control rod to move up and down through the tooth groove.
[0018] In one embodiment of this utility model, the toothed plate has only one pair of teeth at each end. By setting teeth only at both ends of the toothed plate, when the gear first moves up and down, the toothed plate drives the control rod to move up and down through the gear. The control rod pushes the moving part away from the rotating head, so that the plug is temporarily pulled out of the slot to prevent the plug from obstructing the subsequent rotation of the rotating head. Since the sliding space of the control rod is limited, no teeth are set in the middle position of the toothed plate. After the teeth on the toothed plate move over the gear, the elastic force of the first spring and the second spring will push the control rod and the moving part back to their original positions, so that the plug is inserted into the slot.
[0019] Compared with the prior art, this utility model reduces motor wear and improves motor service life by setting a self-locking mechanism to self-lock the blades in both open and closed states. Attached Figure Description

Detailed Implementation
[0033] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0034] like Figure 1-10 As shown, an air intake grille system in one embodiment of the present invention includes an air intake grille and a control module thereon. The air intake grille includes: an outer frame 1, multiple grille plates 103, a grille control component and a self-locking mechanism 2.
[0035] The outer frame 1 contains a pair of grille mounting areas 101 and a control area 102 located between the pair of grille mounting areas 101. Multiple grille plates 103 are mounted within the pair of grille mounting areas 101, and rotating heads 104 are fixed to both ends of each grille mounting area 101. A grille control assembly is mounted within the control area 102 and fixedly connected to one end of the rotating head 104 located within the control area 102. The grille control assembly includes multiple control arms 106 and a control element 109. One end of each control arm 106 is fixedly connected to one of the multiple rotating heads 104, and the other end is movably mounted on the side wall of the control element 109, which slides within the control area 102.
[0036] The self-locking mechanism 2 is installed inside the two side walls of the control area 102. The self-locking mechanism 2 includes: multiple moving parts 201, control rod 206, control components and multiple elastic elements. The end of the moving part 201 near the rotating head 104 is fixed with a plug 202. The rotating head 104 has a pair of slots 203 that are adapted to the plug 202. The control rod 206 slides up and down on the two side walls of the control area 102 and passes through the multiple moving parts 201. The control rod 206 is provided with arc-shaped grooves 207 at the moving parts 201. Multiple elastic elements are respectively installed at the two ends of the upper end of the control rod 206 and the end of the moving part 201 away from the plug 202.
[0037] In use, the control component 109 is moved up and down by an external control device. The control component 109 drives the rotating head 104 to rotate through the control arm 106. The rotating head 104 drives the grid plate 103 to rotate, thereby realizing the opening and closing of the grid plate 103.
[0038] When the control component 109 moves up and down, it drives the control lever 206 to move up and down via the control assembly. As the control lever 206 moves up and down, the inclined surface of the arc groove 207 pushes the moving component 201 to move in the opposite direction to the rotating head 104, thereby causing the moving component 201 to pull the plug 202 out of the slot 203. When the control assembly stops driving the control lever 206, the elastic elements installed at both ends of the upper part of the control lever 206 and the end of the moving component 201 away from the plug 202 push the control lever 206 and the moving component 201 back to their original positions. The moving component 201 then inserts the plug 202 into another slot 203, thereby locking the grille plate 103. The positions of the pair of slots 203 correspond to the open and closed positions of the grille plate 103, respectively.
[0039] like Figure 3-5 As shown, the upper and lower ends of the grating plate 103 are both carved with interlocking slots 105. The slots 105 at the upper and lower ends of the grating plate 103 respectively engage with the slots 105 of the two grating plates 103 above and below it. By interlocking the slots 105 on the two grating plates 103, the sealing performance of the grating plate 103 when closed is improved. Multiple control arms 106 are each equipped with a second pulley 108 on the side away from the rotating head 104 and on the same axis as the rotating head 104. The control component 109 has sliding grooves 112 carved on both sides of its side walls. The multiple second pulleys 108 slide in a pair of sliding grooves 112. The control component 109 slides on the multiple second pulleys 108 on both sides through the pair of sliding grooves 112 on its side walls, thereby achieving a sliding setting in the control area 102.
[0040] like Figure 1-4 As shown, a lead screw 111 is rotatably mounted within the control area 102. One end of the lead screw 111 is connected to a drive device 110. The lead screw 111 is threadedly connected to the control component 109. The drive device 110 drives the lead screw 111 to rotate, causing the lead screw 111 to move the control component 109 up and down. A first pulley 107 is mounted on the end of the control arm 106 away from the rotating head 104. Multiple control grooves 113 are vertically carved on both sides of the control component 109. The first pulley 107 slides in the control grooves 113. The control component 109 slides in the control grooves 113 via the first pulley 107, thereby realizing the movable connection between the control arm 106 and the control component 109. Thus, when the control component 109 moves up and down, the control component 109 drives the rotating head 104 to rotate via the control arm 106.
[0041] like Figure 3As shown, the control slot 113 is a rectangle with both length and width greater than the diameter of the first pulley 107. When the control member 109 drives the rotating head 104 to rotate through the control arm 106, the first pulley 107 moves in an arc with the rotating head 104 as the axis. Therefore, the control slot 113 is a rectangle with both length and width greater than the diameter of the first pulley 107 so that when the control member 109 drives the first pulley 107 to move upward, there is room for the first pulley 107 to move. In addition, the vertical width of the control slot 113 is set to be greater than the diameter of the first pulley 107 so that when the control member 109 moves up and down, it first controls the plug 202 to move out of the slot 203 through the toothed plate 211 and the gear 209.
[0042] like Figure 6-10 As shown, a third pulley 205 is installed on one side of the arc-shaped groove 207 within the movable component 201. The third pulley 205 slides on the arc-shaped groove 207, thereby reducing the friction between the movable component 201 and the arc-shaped groove 207 when the control lever 206 pushes the movable component 201 through the arc-shaped groove 207 to pull the plug 202 out of the slot 203. A first spring 204 is installed at the end of the multiple movable components 201 furthest from the plug 202. The elastic force of the first spring 204 is used to push the movable component 201 towards the rotating head 104 when no external force is applied, causing the plug 202 to insert into the slot 203. The elastic elements installed at the upper and lower ends of the control lever 206 are the second springs 208. A pair of second springs 208 are used to push the control lever 206 when it is not pushed by an external force, so that the control lever 206 returns to its original position, which is the position of the third pulley 205 located at the innermost part of the arc of the arc groove 207.
[0043] like Figure 6-7 As shown, the control assembly includes a gear 209, a toothed groove 210, and a pair of toothed plates 211. The gear 209 is mounted on the side wall of the control area 102. The toothed groove 210 is carved into the side wall of the control lever 206 near the gear 209 and meshes with it. The pair of toothed plates 211 are mounted on the two outer side walls of the control component 109 and mesh with the gear 209. When the control component 109 moves up and down, the toothed plates 211 drive the gear 209 to rotate, and the gear 209, through the toothed groove 210, drives the control lever 206 to move up and down.
[0044] like Figure 6-7As shown, the toothed plate 211 has only one pair of teeth at each end. By setting teeth only at both ends of the toothed plate 211, when the gear 209 first moves up and down, the toothed plate 211 drives the control rod 206 to move up and down through the gear 209. The control rod 206 pushes the moving part 201 to move away from the rotating head 104, so that the plug 202 is temporarily pulled out of the slot 203 to prevent the plug 202 from obstructing the subsequent rotation of the rotating head 104. Since the sliding space of the control rod 206 is limited, no teeth are set in the middle position of the toothed plate 211. After the teeth on the toothed plate 211 move over the gear 209, the elastic force of the first spring 204 and the second spring 208 will push the control rod 206 and the moving part 201 back to their original positions, so that the plug 202 is inserted into the slot 203.
[0045] Working principle: The drive device 110 drives the lead screw 111 to rotate, which in turn drives the control component 109 to move up and down. The control component 109 drives the rotating head 104 to rotate through the control arm 106. The rotating head 104 drives the grid plate 103 to rotate, thereby realizing the opening and closing of the grid plate 103.
[0046] When the control component 109 moves up and down, it drives the gear 209 to rotate via the toothed plate 211. The gear 209 drives the control rod 206 to move up and down via the tooth groove 210. When the control rod 206 moves up and down, it pushes the moving component 201 to move in the opposite direction to the rotating head 104 via the inclined surface of the arc groove 207, thereby causing the moving component 201 to pull the plug 202 out of the slot 203. After the toothed plate 211 moves past the gear 209, the gear 209 is no longer pushed by external force. The elastic force of the first spring 204 and the second spring 208 respectively pushes the control rod 206 and the moving component 201 back to their original positions. The moving component 201 then inserts the plug 202 into another slot 203, thereby locking the grille plate 103. The positions of the pair of slots 203 correspond to the open and closed positions of the grille plate 103, respectively.
[0047] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics.
