However, currently, there are no...
[0003] Therefore, it is crucial to provide active air intake grilles with multi-angle blades, especially active air intake grilles with multi-angle blades driven by a single motor. Summary of the Invention
[0004] To address the aforementioned problems, the present invention aims to provide an active air intake grille that drives multi-angle blade movement with a single motor. By employing a three-way control arrangement consisting of the connecting rod body, the drive shaft, and the grille, as well as a nested two-way control arrangement consisting of the connecting rod body, the blades, and the grille, the invention achieves the goal of synchronously driving multi-angle blades with a single motor.
[0005] The objective of this invention can be achieved through the following technical solutions:
[0006] The present invention provides an active air intake grille with single motor driving multi-angle blade movement, comprising: a motor, a connecting rod assembly connected to the motor via a drive shaft, and a grille and a blade assembly sequentially arranged on the side of the connecting rod assembly away from the motor;
[0007] The grid is curved, and the blade assembly is formed by sequentially splicing together several blade units arranged in an array. Each blade unit includes several blade bodies, and each blade body is provided with a first boss connected to the connecting rod assembly and a second boss connected to the grid.
[0008] In each column of blade units, the adjacent blade bodies are different along the line connecting the second boss, and in each row of blade units, the adjacent blade bodies are different along the line connecting the second boss; thus, the blade assembly has a profile that matches the curved surface of the grille.
[0009] In one embodiment of the present invention, two sets of drive shafts are provided and symmetrically arranged along the left and right sides of the motor. One end of the drive shaft is a spline end and is connected to the motor through the spline end (the spline end is inserted into the motor).
[0010] In one embodiment of the present invention, the drive shaft is connected to the connecting rod assembly via a first connector.
[0011] In one embodiment of the present invention, a plurality of the first connecting members are provided and are arranged in parallel at intervals on the drive shaft;
[0012] The first connector is provided with a first guide hole and a second guide hole. The first connector is sleeved on the drive shaft through the first guide hole and connected to the connecting rod assembly through the second guide hole.
[0013] In one embodiment of the present invention, the linkage assembly includes a plurality of linkage bodies symmetrically arranged along the motor, the number of which is the same as the number of the first connecting members;
[0014] The bottom of the connecting rod body is provided with a first insert that is adapted to the second guide hole;
[0015] The top of the connecting rod body is provided with a second insert, and is connected to the grille through the second insert and the second connector;
[0016] The connecting rod body has several first pins in the middle, and is connected to the blade bodies in the same row in sequence through the first pins.
[0017] In one embodiment of the present invention, the second connector is provided with a third insert and a third guide hole;
[0018] The second connector is connected to the grid via the third insert and to the second insert via the third guide hole.
[0019] In one embodiment of the present invention, a fourth guide hole adapted to the third insert is provided at the position where the grille connects to the connecting rod body.
[0020] In one embodiment of the present invention, the first boss is disposed on the top of the blade body, and the second boss is disposed on the two sides of the blade body.
[0021] In one embodiment of the present invention, the grille is provided with a gap that allows the first boss to protrude;
[0022] A second pin is provided at the position where the grille connects to the blade, and the second pin is connected to the second boss.
[0023] In one embodiment of the present invention, the first boss is provided with a circular hole adapted to the first pin, and the second boss is provided with a circular hole adapted to the second pin.
[0024] Wherein, the length of the first pin is greater than the width of the first boss. When the connecting rod body drives the blade body to move, it will cause an offset along the width direction of the first boss. At this time, the setting of the first pin can prevent the blade body from detaching from the connecting rod body and has a buffering effect.
[0025] The length of the second pin is greater than the width of the second boss. When the grille drives the blade body to move, it will deviate along the width direction of the second boss. At this time, the setting of the second pin can prevent the blade body from detaching from the connecting rod body and has a buffering effect.
[0026] In one embodiment of the present invention, the drive shaft is connected to the bottom of the grille via a pressure plate;
[0027] The pressure plate has a groove in the middle that matches the outer diameter of the drive shaft. One end of the pressure plate is embedded in the bottom of the grille, and the other end is connected to the bottom of the grille by screws.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] The active air intake grille of the present invention, which drives the multi-angle blade movement with a single motor, can achieve the purpose of synchronous movement of the multi-angle blade body through a single motor, and has high stability during movement and strong adaptability in application.

[0049] Unless otherwise specified, the structures or components used in the following embodiments are all conventional structures or components in the art, and are sufficient to achieve the corresponding functions.
[0050] Example 1
[0051] This embodiment provides an active air intake grille with a single motor driving multi-angle blade movement, which is connected to an external frame during use, such as... Figures 1-14 As shown, a motor 1 mounted on a frame is connected to a connecting rod assembly 4 via a drive shaft 2. A grille 6 and a blade assembly 7 are sequentially arranged on the side of the connecting rod assembly 4 away from the motor 1. The grille 6 is curved, and the blade assembly 7 is formed by sequentially splicing several blade units arranged in an array. Each blade unit includes several blade bodies 701. Each blade body 701 is provided with a first boss 702 connected to the connecting rod assembly 4 and a second boss 703 connected to the grille 6.
[0052] In each column of blade units, the adjacent blade bodies 701 are connected along the line direction of the second boss 703, and in each row of blade units, the adjacent blade bodies 701 are connected along the line direction of the second boss 703, so that the blade assembly 7 has a profile that is adapted to the curved surface of the grille 6.
[0053] Furthermore, the drive shaft 2 is provided in two sets and is symmetrically arranged on the left and right sides of the motor 1. One end of the drive shaft is a spline end, which is connected to the motor 1 (the spline end is inserted into the motor 1).
[0054] Furthermore, the drive shaft 2 is connected to the connecting rod assembly 4 via a first connecting member 3 (which provides power to the connecting rod assembly 4). Several first connecting members 3 are provided and are arranged in parallel at intervals on the drive shaft 2. The first connecting member 3 is provided with a first guide hole 301 and a second guide hole 302. The first connecting member 3 is sleeved on the drive shaft 2 through the first guide hole 301 and connected to the connecting rod assembly 4 through the second guide hole 302.
[0055] Furthermore, the connecting rod assembly 4 includes a plurality of connecting rod bodies 401 symmetrically arranged along the motor 1, the number of which is the same as the number of the first connecting members 3; the bottom of the connecting rod body 401 is provided with a first insert 402 adapted to the second guide hole 302; the top of the connecting rod body 401 is provided with a second insert 404, and is connected to the grille 6 through the second insert 404 and the second connecting member 5; the middle part of the connecting rod body 401 is provided with a plurality of first pins 403, and is sequentially connected to the blade bodies 701 in the same row through the first pins 403.
[0056] Furthermore, the second connector 5 is provided with a third insert 501 and a third guide hole 502; wherein, the second connector 5 is connected to the grille 6 through the third insert 501 (the position where the grille 6 is connected to the connecting rod body 401 is provided with a fourth guide hole adapted to the third insert 501), and is connected to the second insert 404 through the third guide hole 502.
[0057] Furthermore, the first boss 702 is disposed on the top of the blade body 701, and the second boss 703 is disposed on the two sides of the blade body 701. The grille 6 is provided with a gap that allows the first boss 702 to extend. A second pin 601 is provided at the position where the grille 6 connects with the blade, and is connected to the second boss 703 through the second pin 601.
[0058] Furthermore, the first boss 702 is provided with a circular hole that matches the first pin 403, and the second boss 703 is provided with a circular hole that matches the second pin 601.
[0059] In this configuration, the length of the first pin 403 is greater than the width of the first boss 702. When the connecting rod body 401 drives the blade body 701 to move, it will deviate along the width direction of the first boss 702. At this time, the first pin 403 can prevent the blade body 701 from detaching from the connecting rod body 401 and has a buffering effect. The length of the second pin 601 is greater than the width of the second boss 703. When the grille 6 drives the blade body 701 to move, it will deviate along the width direction of the second boss 703. At this time, the second pin 601 can prevent the blade body 701 from detaching from the connecting rod body 401 and has a buffering effect.
[0060] Furthermore, the drive shaft 2 is connected to the bottom of the grille 6 via a pressure plate 8; the pressure plate 8 has a groove in the middle that matches the outer diameter of the drive shaft 2, one end of the pressure plate 8 is embedded in the bottom of the grille 6, and the other end is connected to the bottom of the grille 6 via a screw 9.
[0061] When in use, start motor 1. The output shaft of motor 1 drives the drive shaft 2 to rotate. The drive shaft 2 drives the connecting rod body 401 through the first connecting piece 3, which in turn drives the grille 6, and further drives the blade body 701 to rotate, thereby opening or closing the blade body 701 (adjustable as needed).
[0062] Since different blade bodies 701 can form blade assemblies 7 that are compatible with the curved grid 6, the solution of this embodiment can realize the synchronous movement of multi-angle blade bodies 701 driven by a single motor 1.
[0063] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments (e.g., variations in the number of connecting rods, variations in the angle between blades, variations in the shape of the connecting rods, variations in the shape of the blades, variations in the number of blades, the arrangement of the blades, and their orientation). Improvements and modifications made by those skilled in the art based on the interpretation of the present invention, without departing from the scope of the invention, should be within the protection scope of the present invention.
