It is important whether the blade groups on the left and right sides of the active air intake grille are synchronously linked during the opening and closing processes.

[0003] In response to the above problems, the following solutions are generally adopted:

[0004] Two actuators are used to drive the split blades on the left and right sides of the active air intake grille respectively, and the controller is used for logic control to achieve the effects of synchronous opening and closing of the split blades on the left and right sides of the active air intake grille;

[0005] For the above solution, two modules are used to drive separately, which has a complex structure and is prone to controller control logic problems. In addition, two actuators are used at the same time, which greatly increases the product cost. Summary of the invention

[0006] The utility model aims to solve the above problems in the prior art and proposes a motion mechanism for a split-type active air intake grille which only needs one power source to synchronously control the opening or closing of two grille groups.

[0007] The purpose of the utility model can be achieved through the following technical solutions: a movement mechanism of a split-type active air intake grille, comprising:

[0008] a frame, wherein a pair of grille groups are disposed within the frame;

[0009] The rotating disk is movably arranged in the middle of the frame. Each of the grille groups is provided with a moving component, and each of the moving components is movably connected to the rotating disk. When the rotating disk rotates, the moving component moves relative to the rotating disk. At the same time, the moving component drives the corresponding grille group to open or close.

[0010] In the above-mentioned movement mechanism of the split-type active air intake grille, it also includes: a fixed plate, which is coaxially arranged with the rotating plate, and the rotating plate can rotate relative to the fixed plate.

[0011] In the above-mentioned movement mechanism of a split-type active air intake grille, each of the moving components includes a pull rod hinged to the corresponding grille group and a sliding rod with one end movably connected to the rotating disk, and the sliding rod is hinged to the adjacent pull rod.

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 — Figure 5 As shown, the motion mechanism of a split-type active air intake grille of the utility model comprises a frame 100 , a grille set 200 , a rotating disk 300 and a moving assembly 400 .

[0027] A pair of grille groups 200 are provided in the frame 100, and a rotating disk 300 is movably provided in the middle of the frame 100. A moving component 400 is provided on each of the grille groups 200, and each of the moving components 400 is movably connected to the rotating disk 300. When the rotating disk 300 rotates, the rotating disk 300 applies a force to the two moving components 400 at the same time, and the moving components 400 move laterally relative to the rotating disk 300, so that the moving components 400 drive the corresponding grille groups 200 to open or close. In this way, one driving source can drive the two grille groups 200 to open or close at the same time.

[0028] In the present invention, the actuator 600 and the fixing plate 500 are both installed inside the car, and the actuator 600 and the fixing plate 500 are both stationary relative to the car.

[0029] The motion mechanism also includes a fixed disk 500 and an actuator 600 for driving the rotating disk 300 to rotate. The fixed disk 500 is provided with an orientation groove 510, and the orientation groove 510 passes through the center of the fixed disk 500. The rotating disk 300 is provided with a gear 320 connected to the actuator 600. Each of the moving components 400 includes a pull rod 410 hinged to the corresponding grid group 200 and a sliding rod 420 movably connected to the rotating disk 300 at one end. The sliding rod 420 is hinged to the adjacent pull rod 410, and each sliding rod 420 is slidably connected to the orientation groove 510. The fixed disk 500 is coaxially arranged with the rotating disk 300, and the rotating disk 300 can rotate relative to the fixed disk 500. Furthermore, a through shaft (not marked in the figure) is provided in the middle of the fixed disk 500, and the through shaft movably passes through the rotating disk 300 to realize rotation. The disk 300 rotates relative to the fixed disk 500. During operation, when the rotating disk 300 rotates, the rotating disk 300 will apply a thrust to the sliding rod 420, and the sliding rod 420 has and can only move along the trajectory of the directional groove 510. In this way, the sliding rod 420 can move toward or away from the center direction of the rotating disk 300. In this process, because the sliding rod 420 is hinged with the corresponding pull rod 410, the end of the pull rod 410 away from the sliding rod 420 is hinged with the corresponding grille group 200. In this way, the sliding rod 420 can drive the grille group 200 to open or close through the pull rod 410; in addition, the grille group 200 and the sliding rod 420 are both hinged with the pull rod 410. In this way, the stress generated between the grille group 200 and the sliding rod 420 can be effectively offset, thereby ensuring that the grille group 200 can be smoothly opened or closed.

[0030] In the present invention, a side of the driving groove 310 away from the center thereof is called an outer side 311 , and a side of the driving groove 310 close to the center thereof is called an inner side 312 .

[0031] A driving block 421 is provided at one end of the sliding rod 420 away from the pull rod 410. Therefore, the movement direction of the driving block 421 is and can only be moved back and forth along the trajectory of the directional groove 510. The rotating disk 300 is provided with an arc-shaped driving groove 310, and the driving block 421 is movably clamped in the corresponding driving groove 310. When the rotating disk 300 rotates around the through-axis, the outer edge 311 will push the driving block 421 and move the driving block 421 along the directional groove 510 toward the through-axis direction, so that the pull rod 410 pulls the grille group 200 to open. When the rotating disk 300 rotates in the opposite direction around the through-axis, the inner edge 312 will push the driving block 421 and move the driving block 421 along the directional groove 510 away from the through-axis direction, so that the pull rod 410 pulls the grille group 200 to close. During this process, the rotating disk 300 can stop rotating at any time to control the opening angle of the grille group 200, so that the grille group 200 can achieve the effect of multi-angle opening.

[0032] The two driving grooves 310 are symmetrical with respect to the center of the rotating disk 300 , wherein the through-axis is located exactly on the center of the rotating disk 300 . Through the arrangement of this structure, the actuator 600 can simultaneously control the synchronous movement of the two sliding rods 420 .

[0033] Each of the grille groups 200 includes a plurality of blades 210 movably arranged in the frame 100, and the plurality of blades 210 in each grille group 200 are connected by a synchronization rod 220, and the synchronization rod 220 is provided with a fixed rod 221 hinged to the corresponding pull rod 410, and each of the blades 210 is provided with a first rotating block 211 hinged to the frame 100 on both sides, and each of the blades 210 is provided with a second rotating block 212 hinged to the synchronization rod 220 on one side. When the pull rod 410 drives the fixed rod 221 to move, because the blade 210 is hinged to the frame 100 through the first brick, and the blade 210 is hinged to the synchronization rod 220 through the second brick, the frame 100 is stationary relative to the car, and therefore, the synchronization rod 220 will drive each blade 210 to rotate around the first rotating block 211, thereby completing the opening or closing of each blade 210.

[0034] In addition, the fixed rod and the pull rod, as well as the pull rod and the sliding rod, are connected by a pin shaft (not marked in the figure), and retaining springs (not marked in the figure) are provided at both ends of the pin shaft to prevent the pin shaft from sliding, so as to prevent the pull rod and the sliding rod from moving on the corresponding pin shaft, thereby ensuring that one end of the pull rod can and can only rotate around the corresponding pin shaft relative to the fixed rod, and the other end of the pull rod can and can only rotate around the corresponding pin shaft around the sliding rod. Secondly, the sliding rod can and can only move in a directional manner along the corresponding directional groove. In this way, the movement direction of each component of the motion mechanism during the movement process can be limited, thereby avoiding the situation where the pull rod and the fixed rod, as well as the pull rod and the sliding rod, are stuck due to misalignment, that is, ensuring that the motion mechanism can work stably.

[0035] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
