Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an active air intake grille blade, an air intake grille assembly and a vehicle. Background Art

[0002] With the improvement of environmental protection requirements and the development of the automobile industry, the requirements for energy conservation and emission reduction of vehicles are getting higher and higher. The active air intake grille can change the opening and closing of the air intake grille to control the intake volume and wind resistance, thereby improving fuel economy and quickly reaching the optimal operating temperature of the engine. Therefore, the application of active air intake grilles is increasing. Active air intake grilles are generally divided into built-in and external types. The external active air intake grille is more and more used because it can meet the performance of traditional active air intake grilles and increase the three-dimensional sense of the vehicle and the appearance design aesthetics that conform to the trend of the times.

[0003] The current external active air intake grille, for example, the patent with publication number CN116834542A discloses an active air intake grille, which includes a frame, blades, connecting rods and a driving member. The blades are horizontally rotatably arranged on the frame and are distributed in multiple numbers along the vertical direction of the frame. A toggle shaft is fixed to the same end of the blades, and the axis of the toggle shaft is parallel to the rotation axis of the blades. The connecting rod is arranged on the frame along the distribution direction of the blades, and the toggle shaft is rotatably connected to the connecting rod. The driving member drives the connecting rod to open or close the blades. This solution fixes the toggle shaft at the end of the blade and rotatably connects the toggle shaft to the connecting rod. When opening or closing is required, the driving member only needs to drive the connecting rod to move, and the connecting rod can drive multiple blades to rotate to open or close.

[0004] Although the above-mentioned active air intake grille can drive multiple blades to rotate open or close, the current active air intake grille still has the following problems: In order to ensure that the blades of this type of active air intake grille with horizontally arranged blades are sufficiently rigid, the horizontal dimension cannot be enlarged, resulting in a small size of the active air intake grille; if the horizontal dimension is enlarged according to the above scheme, the blade rigidity will be soft, and the blades are prone to deformation. In addition, the front of the conventional external active air intake grille is a flat surface with reinforcing ribs arranged on the back. The active air intake grille is a large flat surface when the blades are closed, and the back reinforcement structure is exposed when the blades are opened, which affects the aesthetic appearance of the entire vehicle. In addition, the current active air intake grille has a complex internal drive structure, and the motion transmission route is long, which is prone to problems such as failure. Summary of the invention

[0005] The purpose of the present invention is to provide an active air intake grille blade, an air intake grille assembly and a vehicle, so as to solve the problem that if the lateral dimension of the current active air intake grille is enlarged, the blade stiffness will be too soft and the blade deformation will be easy to occur.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] An active air intake grille blade includes an outer blade plate and an inner blade plate, the outer blade plate and the inner blade plate are buckled and fixed, and a cavity is formed between the outer blade plate and the inner blade plate. The technical solution sets the blade as a split outer blade plate and an inner blade plate, and forms a cavity between the outer blade plate and the inner blade plate, so that the rigidity of the entire blade is greatly improved compared with the traditional blade; under the same rigidity, the blade can be made longer than the traditional blade, so as to meet the requirements of making a large-sized active air intake grille.

[0008] Furthermore, both sides of the blade outer panel in the length direction are provided with outer panel flanges bent to the same side, and both sides of the blade inner panel in the length direction are provided with inner panel flanges bent to the same side. The blade outer panel in the technical solution is provided with outer panel flanges bent to the same side, that is, the longitudinal section is in the shape of "["; the blade inner panel is provided with inner panel flanges bent to the same side, that is, the longitudinal section is in the shape of "]"; when the blade outer panel and the blade inner panel are assembled, the "["-shaped blade outer panel is buckled on the "]"-shaped blade inner panel, and the section forms a "[]"-shaped cavity, and the stiffness of the entire blade is greatly improved compared with the traditional blade; under the same stiffness, the blade can be made longer than the traditional blade, thereby meeting the requirements for making large-size active air intake grilles. Moreover, with such a setting, the reinforcing ribs can be set on the inner plate of the blade on the cavity side, further improving the rigidity of the blade, thereby avoiding setting the reinforcing ribs on the outer wall of the inner plate of the blade. The back of the blade can be designed as a smooth plane. When the blade is in the open state, there is no redundant design on the back of the blade, and the visual effect is clearer.

[0009] Furthermore, the outer wall of the inner plate flange is close to the inner wall of the outer plate flange, the edge of the outer plate flange is provided with an undercut clip, the inner plate flange is provided with an outer flange, and the outer flange clip is arranged between the undercut clip and the blade outer plate. With such an arrangement, the blade inner plate is buckled into the blade outer plate, and the outer flange on the blade inner plate is clamped by the undercut clip on the blade outer plate, thereby preventing the blade outer plate and the blade inner plate from falling off during assembly.

[0010] Furthermore, the blade inner plate is provided with a first reinforcing rib on one side close to the blade outer plate, and the height of the first reinforcing rib is equal to the height of the inner plate flange. The blade inner plate of the technical solution is provided with the first reinforcing rib, and after the blade outer plate and the blade inner plate are assembled, the first reinforcing rib is supported on the inner surface of the blade outer plate, which can further improve the rigidity of the entire blade.

[0011] Furthermore, a shielding flange is provided on the edge of the outer plate flange in the length direction. When multiple blades are combined and the active air intake grille is closed, the shielding flange can shield the gap between two adjacent blades, thereby making the entire active air intake grille more closed and more beautiful.

[0012] Furthermore, a welding column is provided on one side of the blade outer plate close to the blade inner plate, a welding hole matching the welding column is provided on the blade inner plate, and the welding column is fixedly installed in the welding hole. This technical solution utilizes the cooperation of the welding column and the welding hole to fix the blade outer plate and the blade inner plate together, and the connection is stable.

[0014] Furthermore, the driving assembly includes a motor, a driving connecting rod and a driving connecting plate. A fixed frame is provided on the grille body, and the fixed frame divides the grille body into a first blade frame and a second blade frame. The first blade frame and the second blade frame are both rotatably provided with a plurality of active air intake grille blades; the motor is fixedly mounted on the fixed frame, the driving connecting rod is mounted on the motor, and the driving connecting plate is slidably arranged on the fixed frame. The motor drives the driving connecting rod to rotate, the driving connecting rod drives the driving connecting plate to slide in an arc, and the driving connecting plate drives the active air intake grille blades to rotate. The technical solution is arranged in this way. When in use, the motor drives the driving connecting rod to rotate, and the driving connecting rod drives the driving connecting plate to slide in an arc, so that the arc sliding of the driving connecting plate drives the opening or closing of the blades on the first blade frame and the second blade frame.

[0015] Furthermore, the driving connecting rod is provided with a U-shaped groove and a connecting shaft, and the connecting shaft is connected to the motor in a transmission manner; the driving connecting plate is provided with two long strip holes symmetrical along the longitudinal center line, and the long strip holes are provided with a transverse first driving shaft, and the first driving shaft is inserted into the U-shaped groove of the driving connecting rod. The technical solution is arranged in such a way that the motor drives the driving connecting rod to rotate through the connecting shaft. When the driving connecting rod rotates, because the driving connecting rod is provided with a U-shaped groove, the driving connecting rod is arranged on the first driving shaft through the U-shaped groove fork. When the driving connecting rod rotates, the arc motion of the driving connecting plate can be realized. Such an arrangement makes the structure of the entire driving assembly simpler and less prone to failure.

[0016] Furthermore, both ends of the inner plate of the blade are provided with side flanges, and the side flanges at both ends are provided with coaxial rotating shafts, and a second driving shaft is also provided on a side flange close to the fixed frame, and the end of the second driving shaft away from the side flange is installed on the driving connecting plate; the inner plate of the blade is rotatably installed on the first blade frame or the second blade frame through the rotating shaft. In this technical solution, the arc movement of the driving connecting plate drives the arc movement of the second driving shaft, because the rotating shaft of the blade is fixed in position and can only rotate, so when the driving connecting plate moves downward in an arc, the second driving shaft moves downward in an arc, and finally opens the blade.

[0017] Furthermore, blade frame flanges are provided on both sides of the first blade frame and the second blade frame, and the blade frame flanges on both sides are respectively provided with first frame holes and second frame holes, and a drive frame hole is also provided on the blade frame flange close to the fixed frame side; the rotating shafts at both ends of the blades are respectively rotatably arranged in the first frame hole and the second frame hole; the driving connecting plate is a U-shaped structure in the width direction, and blade driving holes are provided on both sides of the driving connecting plate, and the second driving shaft rotates through the driving frame hole and the blade driving hole. In this technical solution, the blades can be installed on the first blade frame and the second blade frame by means of the rotating shaft, and can be rotated by means of the rotating shaft; and the second driving shaft can also be installed on the driving connecting plate through the blade driving hole, and the movement of the driving connecting plate is utilized to realize the arc movement of the second driving shaft, thereby driving the blades to rotate.

[0018] Furthermore, the end of the second drive shaft is provided with an anti-dropping clamp, and the anti-dropping clamp is clamped on the blade drive hole. The technical solution is arranged in this way to prevent the second drive shaft from falling off from the drive connecting plate during rotation.

[0019] Furthermore, a circular boss is provided at the end of the rotating shaft away from the fixed frame, the first frame holes are all open U-shaped semicircles, the rotating shaft is clamped in the first frame hole, and a blade mounting plate that closes the first frame hole is detachably provided on the grille body. With such a configuration of the technical solution, when installing the blades, the rotating shaft close to the fixed frame can be first inserted into the second frame hole, and then the rotating shaft away from the fixed frame can be clamped into the first frame hole in the shape of a U-shaped semicircle, and then the blade mounting plate can be installed on the grille body, making installation and removal more convenient.

[0020] Furthermore, the fixing frame flanges are provided on both sides of the fixing frame, and the fixing frame flanges on both sides are provided with an upper reinforcement plane and a lower reinforcement plane, the upper reinforcement plane is provided with an upper limit block, and the lower reinforcement plane is provided with a lower limit block. In this technical solution, the driving connecting rod just contacts the upper reinforcement plane at the upper limit block, and the upper reinforcement plane just serves to limit the driving connecting rod from rotating to the upper limit position; the driving connecting rod just contacts the lower reinforcement plane at the lower limit block, and the lower reinforcement plane just serves to limit the driving connecting rod from rotating to the lower limit position; the motor drives the driving connecting rod to move between the upper and lower limit planes to prevent the motor from rotating excessively.

[0021] Furthermore, a weight-reducing groove is provided on one side of the driving connecting rod away from the connecting shaft, and a second reinforcing rib is provided in the weight-reducing groove near the connecting shaft. The weight-reducing groove can reduce the weight of the driving connecting rod, and the second reinforcing rib can make the strength of the connecting shaft greater.

[0022] In a third aspect, the present invention further discloses a vehicle, including a vehicle body, wherein the vehicle body is provided with the above-mentioned active air intake grille blades, or an air intake grille assembly.

The active air intake grille blade of the present invention is configured as a split blade outer plate and a blade inner plate, and a "[]"-shaped cavity is formed on the cross section between the blade outer plate and the blade inner plate, so that the rigidity of the entire blade is greatly improved compared with the traditional blade; under the same rigidity, the blade can be made longer than the traditional blade, thereby meeting the requirements for making a large-size active air intake grille; and, such a design can also set the reinforcing ribs on the blade inner plate on the cavity side, while further improving the rigidity of the blade, it can also avoid setting the reinforcing ribs on the outer wall of the blade inner plate, and the back of the blade can be designed as a smooth plane. When the blade is in the open state, there is no redundant design on the back of the blade, and the visual effect is more refreshing.

[0053] Embodiment 1,

[0054] This embodiment proposes an active air intake grille blade, such as Figure 1-Figure 2 As shown, it includes a blade outer plate 11 and a blade inner plate 12, the blade outer plate 11 and the blade inner plate 12 are buckled and fixed, both sides of the blade outer plate 11 in the length direction are integrally formed with outer plate flanges 111 of about 7 mm bent to the same side, and its longitudinal section is in the shape of "["; both sides of the blade inner plate 12 in the length direction are integrally formed with inner plate flanges 121 slightly less than 7 mm bent to the same side, that is, the longitudinal section is in the shape of "]", and a cavity is formed between the blade outer plate 11 and the blade inner plate 12; when the blade outer plate 11 and the blade inner plate 12 are assembled, the "["-shaped blade outer plate 11 is buckled on the "]"-shaped blade inner plate 12, and the cross-section forms a "[]"-shaped cavity.

[0055] Among them, the width dimension of the blade inner plate 12 of this embodiment is slightly smaller than the width dimension of the blade outer plate 11; in order to ensure the rigidity of the entire blade 1, the blade inner plate 12 of this embodiment also selects a high-strength fiber-reinforced material; Figure 2 As shown, in order to prevent the blade outer plate 11 and the blade inner plate 12 from falling off during assembly, an undercut clip 112 is provided at the edge of the outer plate flange 111, and an outer flange 129 of about 1.2 mm is provided on the inner plate flange 121, and the undercut clip 112 is clamped on the outer flange 129 of the blade inner plate 12. Figure 3 and Figure 4As shown, in order to fix the blade outer plate 11 and the blade inner plate 12, a welding column 113 is integrally formed on one side of the blade outer plate 11 close to the blade inner plate 12, and a welding hole 123 matching the welding column 113 is opened on the blade inner plate 12, and the welding column 113 is fixedly installed in the welding hole 123. Through the cooperation of the welding column 113 and the welding hole 123, the blade outer plate 11 and the blade inner plate 12 are fixedly connected, and the connection is stable.

[0056] In order to further increase the rigidity of the blade 1, the present embodiment Figure 3 and Figure 4 As shown, the blade inner plate 12 is provided with a first reinforcing rib 122 on one side close to the blade outer plate 11, and the height of the first reinforcing rib 122 is equal to the height of the inner plate flange 121. In addition, the position, thickness, and quantity of the reinforcing ribs can also be arranged according to the strength requirements of the blade 1. The blade inner plate is provided with the first reinforcing rib 122, and after the blade outer plate 11 and the blade inner plate 12 are assembled, the first reinforcing rib 122 is supported on the inner surface of the blade outer plate 11, which can further improve the rigidity of the entire blade 1.

[0057] The edge of the blade outer plate 11 in the length direction of this embodiment is provided with a shielding flange 114. Because generally a plurality of blades 1 are mounted on a grille assembly for combination, when the plurality of blades 1 are combined and the active air intake grille is closed, the shielding flange 114 can shield the gap between two adjacent blades 1, thereby making the entire active air intake grille more closed, reducing air leakage, and more beautiful, and can also ensure that the blade 1 can only be rotated backward to open, and after being rotated forward to the closed position, the upper and lower parts are at the limit position and cannot be rotated forward any further.

[0058] Through the above-mentioned arrangement, the present embodiment greatly improves the rigidity of the entire blade 1 compared to the conventional blade 1; at the same rigidity, the blade 1 can be made longer than the conventional blade 1, thereby meeting the requirements for making a large-sized active air intake grille. In addition, the present embodiment arranges the first reinforcing rib 122 on the blade inner plate 12 on the cavity side, further improving the rigidity of the blade 1, thereby avoiding the need to arrange the reinforcing rib on the outer wall of the blade inner plate 12, and the back of the blade 1 can be designed as a smooth plane. When the blade 1 is in the open state, there is no redundant design on the back of the blade 1, and the visual effect is clearer. The blade outer plate 11 of the present embodiment uses high-gloss materials to ensure the appearance quality of the parts, and can also be designed to have the same appearance features and profiles as the bumper and grille assembly according to styling requirements.

[0059] Embodiment 2,

Three blades 1 of Example 1 are rotatably mounted on the first blade frame 22 and the second blade frame 23 from top to bottom. Among them, the drive assembly of this embodiment includes a motor 3, two drive connecting rods 4 and a drive connecting plate 5, and motor drive holes are arranged at both ends of the motor 3. A hole is opened in the middle of the lower flange of the fixed frame 21, and the wiring harness plug-in terminal at the lower end of the motor 3 passes through the hole of the lower flange of the fixed frame 21 on the grille body 2 and is clamped on the edge of the hole. A bolt mounting hole is arranged at the upper end of the motor 3, and the motor 3 is mounted on the active air intake grille body 2 by bolts. In order to stably mount the motor 3, two sets of triangular reinforcing rib planes are arranged on the long flanges on both sides of the fixed frame 21.

[0061] like Figure 8 , Fig. 9 and Fig.12 As shown, the driving connecting rod 4 is provided with a U-shaped groove 41 and a connecting shaft 42 (a spline shaft in this embodiment), and the connecting shaft 42 is fixedly connected to the motor driving hole of the motor 3, and the motor 3 drives the connecting shaft 42 to rotate; the driving connecting plate 5 is slidably arranged on the fixed frame 21, and the motor 3 drives the driving connecting rod 4 to rotate, and the driving connecting rod 4 drives the driving connecting plate 5 to slide in an arc, and the driving connecting plate 5 drives the blade 1 to rotate. When in use, the driving connecting rod 4 is driven by the motor 3 to rotate, and the driving connecting rod 4 then drives the driving connecting plate 5 to slide in an arc, so that the arc sliding of the driving connecting plate 5 drives the blade 1 on the first blade frame 22 and the second blade frame 23 to be opened or closed. Among them, the driving connecting plate 5 of this embodiment is provided with two long strip holes 51 symmetrical along the longitudinal center line, the hole length is 50mm, and the width is 10mm.

In this embodiment, the motor 3 drives the driving connecting rod 4 to rotate through the connecting shaft 42. When the driving connecting rod 4 rotates, because a U-shaped groove 41 with a depth of 25 mm is provided on the driving connecting rod 4, the driving connecting rod 4 is forked on the first driving shaft 52 through the U-shaped groove 41. When the driving connecting rod 4 rotates, the arc motion of the driving connecting plate 5 can be realized. Such a setting makes the structure of the entire driving assembly simpler and less prone to failure.

In this embodiment, the arc movement of the driving connecting plate 5 drives the arc movement of the second driving shaft 126, because the rotating shaft 125 of the blade 1 is fixed in position and can only rotate, so when the driving connecting plate 5 moves in a downward arc, the second driving shaft 126 moves in a downward arc, and finally the blade 1 is opened.

[0063] like Fig.13 and Fig.14 As shown, both sides of the first blade frame 22 and the second blade frame 23 of this embodiment are integrally formed with blade frame flanges, and the blade frame flanges on both sides are respectively provided with first frame holes 24 and second frame holes 25, and the blade frame flange close to the fixed frame 21 is also provided with a drive frame hole 26; the rotating shafts 125 at both ends of the blade 1 are respectively rotatably arranged in the first frame hole 24 and the second frame hole 25; the driving connecting plate 5 is a U-shaped structure in the width direction, and the driving connecting plate 5 is provided with blade driving holes 53 on both sides, and the second driving shaft 126 is rotatably passed through the driving frame hole 26 and the blade driving hole 53.

In this embodiment, when installing the blade 1, the rotating shaft 125 close to the fixed frame 21 can be first inserted into the second frame hole 25, and then the rotating shaft 125 away from the fixed frame 21 can be clamped into the first frame hole 24 in the shape of a U-shaped semicircle, and then the blade mounting plate 27 is installed on the grille body 2, so that installation and removal are more convenient.

An upper limit block 56 is provided at the upper reinforcing plane 54, and a lower limit block 57 is provided at the lower reinforcing plane 55; in this way, the driving connecting rod 4 just contacts the upper reinforcing plane 54 at the upper limit block 56, and the upper reinforcing plane 54 just plays the role of limiting the rotation of the driving connecting rod 4 to the upper limit position; the driving connecting rod 4 just contacts the lower reinforcing plane 55 at the lower limit block 57, and the lower reinforcing plane 55 just plays the role of limiting the rotation of the driving connecting rod 4 to the lower limit position; the motor 3 drives the driving connecting rod 4 to move between the upper and lower limit planes to prevent the motor 3 from rotating excessively.

[0066] In order to reduce the weight of the driving connecting rod, a weight-reducing groove is provided on the side of the driving connecting rod 4 away from the connecting shaft, and a second reinforcing rib is provided in the weight-reducing groove near the connecting shaft 42. The setting of the second reinforcing rib has the effect of making the strength of the connecting shaft 42 greater.

[0067] The active air intake grille blade 1 in this embodiment matches the grille body 2 in appearance, and the surface of the blade 1 and the outer surface of the grille body 2 form the front face shape of the front bumper of the whole vehicle. The outer surface of the blade 1 is designed according to the shape characteristics, the surface of the blade 1 follows the shape of the grille surface, and the shape characteristics on the blade 1 are consistent with the grille.

[0068] The installation and use method of the active air intake grille assembly of this embodiment is as follows:

[0069] Assembly of blades 1, driving connecting rods 4, and grille body 2: The active air intake grille body 2 is divided into a left-right symmetrical first blade frame 22 and a second blade frame 23, and the motor 3, two driving connecting rods 4, and a driving connecting plate 5 are arranged in the middle of the active air intake grille body 2. On the flanges on both sides of the first blade frame 22 and the second blade frame 23 of the air intake grille body 2, three U-shaped semicircular first frame holes 24 are opened on the outside, and three second frame holes 25 are opened on the inside; the flange of the driving connecting plate 5 has three blade driving holes 53.

[0070] The active air intake grille blade 1 and the grille body 2 are assembled: each blade 1 includes two rotating shafts 125 and a second driving shaft 126. The two rotating shafts 125 are assembled on the grille body 2, and the second driving shaft 126 is mounted on the blade 1 driving connecting plate 5. There is a circular boss 128 on the edge of the rotating shaft 125 outside the blade 1. The mounting surface of the grille body 2 is clamped in the groove of the rotating shaft 125. There is a circular boss 128 on the end face of the rotating shaft 125. The active air intake grille body 2 has a row of barrier ribs on the side of the convex point of the rotating shaft 125 of the blade 1 to prevent the blade 1 from moving to both sides when rotating and the friction when the rotating shaft of the blade 1 rotates. The blade 1 and the grille body 2 are installed inside, and the second driving shaft 126 inside the blade 1 is directly inserted into the blade driving hole 53 of the inner flange of the active air intake grille body 2.

[0071] Installation of blade 1 and drive connecting plate 5: There are two anti-dropout clips 127 at the end of the drive shaft of blade 1, which are assembled in the blade drive hole 53 on the drive connecting plate 5. After the anti-dropout clips 127 are assembled, they prevent rotation and dropout. The three blades 1 on the first blade frame 22 and the second blade frame 23 are sequentially installed under the same frame. Assembly of blade 1, grille body 2, and blade mounting plate 27: After the three blades 1 are installed, a blade mounting plate 27 is installed on the U-shaped first frame hole 24 of the active air intake grille body 2 to fix the blade 1.

[0072] Active air intake grille blade 1 rotation process: the motor 3, the driving connecting rod 4, and the driving connecting plate 5 are in the initial position, and the blade 1 is in the closed state, such as Fig.15 . The rotation of the motor 3 drives the driving connecting rod 4 to rotate downward, and the U-shaped groove 41 structure of the driving connecting rod 4 drives the driving connecting plate 5 to move downward. In the process of driving the connecting plate 5 to move downward, the driving shaft of each blade 1 is driven to move. The position of the rotating shaft 125 of the blade 1 is fixed and can only rotate, and the second driving shaft 126 can only rotate and move around the rotating shaft. The motor 3 rotates to the position of the lower limit block 57, and the side of the driving connecting rod 4 contacts the lower limit surface of the middle part of the active air intake grille body 2. The blade 1 drives the connecting plate 5 to drive the blade 1 to rotate 90 degrees to the open position of the blade 1. The active air intake grille blade 1 is fully opened, such as Fig.16 .

[0073] Embodiment 3,

[0074] This embodiment is a vehicle, including a vehicle body, wherein the vehicle body is provided with the active air intake grille blades described in the above-mentioned embodiment 1. The active air intake grille blades of such a vehicle can be made longer than traditional blades at the same rigidity, thereby meeting the requirements for making a large-sized active air intake grille; and the reinforcing ribs can be set on the inner plate of the blade on the cavity side, which can further improve the rigidity of the blade and avoid setting the reinforcing ribs on the outer wall of the inner plate of the blade. The back of the blade can be designed as a smooth plane. When the blade is in the open state, there is no redundant design on the back of the blade, which is more visually refreshing. For such a vehicle, when multiple blades are combined and the active air intake grille is closed, the shielding flange can cover the gap between two adjacent blades, thereby making the entire active air intake grille more closed and more beautiful.

[0075] Embodiment 4,

[0076] This embodiment is a vehicle, including a vehicle body, and the vehicle body is provided with the air intake grille assembly described in the above embodiment 2. Such a vehicle is provided with a motor, a driving connecting rod and a driving connecting plate. When the blades are opened or closed, the motor drives the driving connecting rod to rotate through the connecting shaft. When the driving connecting rod rotates, because a U-shaped groove is provided on the driving connecting rod, the driving connecting rod is provided on the first driving shaft through the U-shaped groove fork. When the driving connecting rod rotates, the arc of the driving connecting plate can move downward, so that the arc of the driving connecting plate slides downward to drive the blades on the first blade frame and the second blade frame to open or close. The whole structure is simpler and less prone to failure.
