Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, and relates to an active air intake grille, as well as an automobile with an active air intake grille. Background Technology

[0002] The grille is an important part of the front of a car. Its main functions are to provide air intake and heat dissipation for the engine. Ordinary grilles are always open, which is good in hot summers, but it is more troublesome in winter.

[0003] An active grille shutter is a type of air intake grille that can actively adjust the opening and closing of the grille blades. This means that an active grille shutter can control air intake and heat dissipation. When the car is driving in low temperatures or during a cold start, the grille shutter can be closed to prevent cold air from directly impacting the radiator for forced cooling, thereby quickly raising the engine's water temperature and saving fuel.

[0004] For example, a Chinese invention patent with application number CN201611208923.1 discloses a vehicle air intake grille, including a bracket and a plurality of connecting shafts sequentially installed on the bracket. The two ends of the connecting shafts are hinged to the bracket, and each connecting shaft is connected to a soft grille piece. When the connecting shaft rotates in the forward direction, the soft grille piece can be wound around the connecting shaft.

[0005] The aforementioned type of air intake grille drives the grille blades to rotate via a connecting shaft (rigid shaft). However, this type of air intake grille is only suitable for non-arc air intake grilles. Currently, many air intake grilles are specially designed with an arc structure to reduce wind resistance, so the grille blades arranged laterally are also arranged in an arc shape. The connecting shaft and linkage structure can only be used for linear transmission, which means that the existing connecting shaft or linkage structure is not suitable for this type of arc-shaped air intake grille. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an active air intake grille and a vehicle.

[0007] The objective of this invention can be achieved through the following technical solution: an active air intake grille, comprising:

[0008] The grille body has an arc-shaped structure;

[0009] A flexible shaft, wherein the entire or part of the flexible shaft is bent according to the arcuate shape of the grid body, and the flexible shaft is rotatably mounted on the grid body;

[0010] The blade assembly includes at least two grid blades, each grid blade is arranged according to the arcuate shape of the grid body, each grid blade is connected to the flexible shaft, and the flexible shaft can drive each grid blade to rotate when it rotates.

[0011] Preferably, the grille body is equipped with a drive motor, the flexible shaft is connected to the drive motor, and the drive motor can drive the flexible shaft to rotate forward and backward to adjust the angle of the grille blades.

[0012] Preferably, the grille body has an arcuate structure in its length direction, and the flexible shaft is arranged along the length direction of the grille body.

[0013] Preferably, the grille body has an air inlet, the grille blades are rotatably located at the air inlet, the number of air inlets is the same as the number of grille blades and they are arranged in a one-to-one correspondence, and each air inlet is arranged along the length direction of the flexible shaft.

[0014] Preferably, the grille body is connected to a plurality of spaced mounting brackets, each of the mounting brackets being arranged along the length direction of the flexible shaft, and the flexible shaft passing through each of the mounting brackets in sequence.

[0015] Preferably, the flexible shaft includes a drive segment located between two adjacent mounting brackets, the number of drive segments being the same as the number of grille bodies and arranged in a one-to-one correspondence, and the grille bodies being located between two adjacent mounting brackets and connected to the drive segment.

[0016] Preferably, the grille blades are provided with connecting pipes, and the drive section passes through the connecting pipes and is fixedly connected to the connecting pipes.

[0017] Preferably, the edge of the grille blade has a limiting portion for abutting against the grille body, and the limiting portion abuts against the grille body when the grille blade is closed.

[0018] Preferably, the grid body has an inclined or arc-shaped structure in its height direction, the number of flexible shafts is two and the two flexible shafts are arranged vertically correspondingly along the height direction of the grid body, the number of blade assemblies is two, the two blade assemblies are arranged according to the inclined or arc-shaped structure in the height direction of the grid body, and the grid blades of the two blade assemblies are respectively connected to the two flexible shafts.

[0019] Secondly, a car was disclosed, including an active grille shutter.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By setting the grid body as an arc surface structure, the flexible shaft can synchronously drive the individual grid blades arranged in an arc plane on the grid body to rotate, thereby achieving the purpose of non-linear transmission.

[0022] 2. The grille body is equipped with a drive motor, which can drive the flexible shaft to rotate in both directions, thereby adjusting the angle of the flexible shaft to control the air intake volume of the air intake grille.

[0023] 3. The grille blades are installed inside the air inlet and can rotate to adjust the size of the air inlet opening. Since the flexible shaft can drive each grille blade on the arc surface to rotate through the arc-shaped drive shaft, the air intake volume of the air inlet can be controlled.

[0024] 4. The flexible shaft is not suspended in the air, but is held on the back of the grid body by the mounting bracket. The various mounting brackets can keep the flexible shaft in a curved state without hindering its rotation.

[0025] 5. In addition to the arc-shaped structure in the length direction, the grille body can also be inclined in the height direction. Due to the special shape of the grille body, a single set of blade assemblies cannot completely cover the air intake. Therefore, two sets of blade assemblies distributed vertically are required. Based on the inclined shape of the grille body in the height direction, two sets of flexible shafts are arranged along the inclined surface parallel to the grille body. The two sets of flexible shafts drive the two sets of blade assemblies arranged along the inclined surface respectively. Attached Figure Description

[0034] In the figure, 100 is the grille body; 110 is the air inlet; 120 is the mounting bracket; 200 is the flexible shaft; 210 is the drive section; 300 is the blade assembly; 310 is the grille blade; 320 is the connecting pipe; 330 is the limiting part; and 400 is the drive motor. Detailed Implementation

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1-8 As shown, an active air intake grille includes: a grille body 100, a flexible shaft 200, and a blade assembly 300. It should be noted that, in the actual structure of this active air intake grille, the flexible shaft 200 solves the blade transmission problem of the air intake grille with an arc shape in the length direction. On the basis of the above, at least two flexible shafts 200 can also be used to solve the transmission problem of multiple sets of blades with an inclined or arc shape in the height direction.

[0037] The grid body 100 has an arc surface structure. The flexible shaft 200 is bent in whole or in part according to the arc surface shape of the grid body 100, and the flexible shaft 200 is rotatably mounted on the grid body 100. The blade assembly 300 includes at least two grid blades 310. Each grid blade 310 is arranged according to the arc surface shape of the grid body 100. Each grid blade 310 is connected to the flexible shaft 200, and the flexible shaft 200 can drive each grid blade 310 to rotate when it rotates.

[0038] Preferably, the grille body 100 has an arc-shaped structure, which can effectively reduce wind resistance and make the appearance of the air intake grille more streamlined. On this basis, the grille blades 310 of the blade assembly 300 are arranged in an arc shape and fit the arc shape of the grille body 100. Since the grille blades 310 are arranged in an arc shape, the traditional straight shaft cannot drive the grille blades 310 to rotate synchronously. However, the flexible shaft 200, which can be bent at will, can drive the grille blades 310 arranged in an arc shape to move. The opening and closing angles of the grille blades 310 can be adjusted synchronously by rotating the flexible shaft 200.

[0039] By setting the grille body 100 as an arc surface structure, the flexible shaft 200 can synchronously drive the individual grille blades 310 arranged in an arc plane on the grille body 100 to rotate, thereby achieving the purpose of non-linear transmission.

[0040] It should also be noted that the flexible shaft 200 is relatively long. In order to drive the rotation of each grid blade 310 arranged in an arc, the part of the flexible shaft 200 connected to each grid blade 310 must be bent according to the arc shape of the grid body 100. The part of the flexible shaft 200 refers to the part of the flexible shaft 200 connected to each grid blade 310. On this basis, the entire flexible shaft 200 can also be bent according to the arc shape of the grid body 100.

[0041] The length direction of the grille body 100 is from the left end to the right end of the grille body 100. Preferably, the grille body 100 has an arc-shaped structure in its length direction, and the flexible shaft 200 is arranged along the length direction of the grille body 100.

[0042] like Figure 1-8 As shown, the flexible shaft 200 requires a power source to drive it in order to rotate the grid blades 310. In order to drive the flexible shaft 200 to rotate, the grid body 100 is equipped with a drive motor 400. The flexible shaft 200 is connected to the drive motor 400, and the drive motor 400 can drive the flexible shaft 200 to rotate in both directions to adjust the angle of the grid blades 310.

[0043] like Figure 1 , Figure 2 , Figure 6 As shown, the grille body 100 is provided with an air inlet 110, and the grille blades 310 are rotatably located at the air inlet 110. The number of air inlets 110 is the same as the number of grille blades 310 and they are arranged in a one-to-one correspondence. Each of the air inlets 110 is arranged along the length direction of the flexible shaft 200.

[0044] Preferably, since each air inlet 110 is arranged along the length of the grille body 100, each air inlet 110 is arranged in an arc shape. The grille blades 310 are installed in the air inlets 110 and can rotate to adjust the opening size of the air inlets 110. Since the flexible shaft 200 can drive each grille blade 310 on the arc surface to rotate through the arc-shaped transmission shaft, the air intake of the air inlet 110 is controlled.

[0045] like Figure 1-3 As shown, the grille body 100 is connected to a plurality of spaced mounting brackets 120, each of the mounting brackets 120 being arranged along the length direction of the flexible shaft 200, and the flexible shaft 200 passing through each of the mounting brackets 120 in sequence.

[0046] The flexible shaft 200 is not suspended in the air, but is held on the back of the grid body 100 by the mounting bracket 120. The various mounting brackets can keep the flexible shaft 200 in a curved state without hindering the rotation of the flexible shaft 200.

[0047] Preferably, the flexible shaft 200 includes a drive segment 210 located between two adjacent mounting brackets 120. The number of drive segments 210 is the same as the number of grille bodies 100 and they are arranged in a one-to-one correspondence. The grille bodies 100 are located between two adjacent mounting brackets 120 and are connected to the drive segments 210.

[0048] The drive section 210 is actually the part of the flexible shaft 200 located between two adjacent mounting brackets 120. Since the two ends of the drive section 210 are limited by the two mounting brackets 120, the drive section 210 can remain stable and can drive the grid body 100 connected to it to rotate.

[0049] The grid blades 310 and the flexible shaft 200 can be connected in various ways, as long as the flexible shaft 200 and the grid blades 310 can be fixed. Preferably, the grid blades 310 are provided with a connecting pipe 320, and the driving section 210 passes through the connecting pipe 320 and is fixedly connected to the connecting pipe 320.

[0050] like Figure 6 , Figure 7 As shown, the edge of the grille blade 310 has a limiting portion 330 for abutting against the grille body 100. When the grille blade 310 is closed, the limiting portion 330 abuts against the grille body 100.

[0051] The limiting part 330 serves as a closing limit. When the air intake grille is closed, each grille blade 310 rotates and seals the air intake 110. At the same time, the limiting part 330 on the edge of the grille blade 310 abuts against the grille body 100 to ensure the sealing of the closure.

[0052] like Figure 1-8 As shown, the grid body 100 has an inclined or arc-shaped structure in its height direction. There are two flexible shafts 200, and the two flexible shafts 200 are arranged vertically and vertically along the height direction of the grid body 100. There are two blade assemblies 300, and the two blade assemblies 300 are arranged according to the inclined or arc-shaped structure in the height direction of the grid body 100. The grid blades 310 of the two blade assemblies 300 are respectively connected to the two flexible shafts 200.

[0053] To further optimize the shape of the grille body 100, in addition to the arc-shaped structure in the length direction, the grille body 100 can also be inclined or arc-shaped in the height direction. Taking the inclined surface as an example, based on the special shape of the grille body 100, a single set of blade assemblies 300 cannot completely cover the air inlet 110, so two sets of blade assemblies 300 distributed vertically are required. Based on the inclined shape of the grille body 100 in the height direction, two sets of flexible shafts 200 are arranged along the inclined surface parallel to the grille body 100, and the two sets of flexible shafts 200 are used to drive the two sets of blade assemblies 300 arranged along the inclined surface respectively.

[0054] like Figure 1 , Figure 6 , Figure 7 As shown, an automobile includes an active grille shutter, which is mounted on the front of the automobile.

[0055] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0056] Furthermore, in this invention, descriptions involving "first," "second," "a," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0057] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; 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 between two elements, unless otherwise explicitly limited.

[0058] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
