Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a split-opening motion mechanism for an automotive air intake grille. Background Technology

[0002] As the automotive industry develops, the requirements for aerodynamics are becoming increasingly stringent. As an important component of automobiles, the air intake grille not only helps control engine temperature but also reduces wind resistance.

[0003] Existing air intake grilles generally use a motion mechanism to drive the blades to swing. However, the effect of the existing motion mechanism driving the blades to swing is a smooth opening. Moreover, the connection method of the motion mechanism is mostly a common snap-fit ​​type, which has the problem of limited opening effect and the blades being locked and failing due to external force. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a split-opening motion mechanism for an automotive air intake grille.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A split-opening motion mechanism for an automotive air intake grille includes a frame body, a blade assembly mounted on the air intake end of the frame body, a linkage assembly for driving the blade assembly to swing relative to each other, and a drive motor for driving the linkage assembly to move.

[0007] The blade assembly includes an upper blade and a lower blade. The connecting rod assembly includes several connecting rods, which are riveted together and respectively rivet the upper blade and the lower blade. The drive motor drives the connecting rods to move so that the blade assembly has a closed state and an open state. When the blade assembly is in the closed state or the open state, the connecting rods form a self-locking angle and are supported on the back of the blade assembly.

[0008] Preferably, the connecting rod includes a drive crank connected to the drive motor, and driven rods respectively connected to both ends of the drive crank. The driven rods are respectively connected to the upper blade and the lower blade, and one end of the driven rod is riveted to the drive crank, and the other end is riveted to the upper blade or the lower blade. With the above improvement, when the output end of the drive motor drives the drive crank to rotate, the drive crank drives the driven rods at both ends to rotate, so that the driven rods drive the upper blade and the lower blade to swing on the frame body respectively. In addition, since the drive crank, driven rod, upper blade and lower blade are riveted together, the resistance is increased, and the locking force of the motor itself can achieve the locking effect.

[0009] Preferably, when the blade assembly is in the closed or open state, the driven rods form a triangular shape and are supported on the back of the blade assembly. Through the above improvements, when the blade assembly is in the closed or open state, the driven rods form triangular supports of different shapes on the back of the blade assembly, thereby increasing the self-locking force. In addition, in combination with the self-resistance of the riveting of the connecting rod and the locking force of the motor, the locking effect of the blade assembly in the open or closed state is greatly improved.

[0010] Preferably, a rivet is inserted between the drive crank and the driven rod, and a damping washer is provided between the rivet and the drive crank, and a damping washer is also provided between the drive crank and the driven rod. Through the above improvements, the damping washer can increase the friction between the drive crank and the driven rod, as well as between the rivet and the drive crank, thereby further improving the locking force of the blade assembly.

[0011] Preferably, the insert shaft is provided with an anti-disengagement snap ring. Through the above improvements, the anti-disengagement snap ring is placed at the bottom of the insert shaft, thereby ensuring the reliability of the connection between the drive crank and the driven rod, as well as the connection between the driven rod and the blade assembly.

[0012] Preferably, the rotating ends of the upper and lower blades are engaged with rotating plates, the rotating plates are riveted to the driven rod via insert shafts, damping washers are provided between the insert shafts and the rotating plates, and damping washers are also provided between the rotating plates and the driven rods. Through the above improvements, the upper and lower blades are connected to the driven rods via rotating plates, and the damping washers are provided between the insert shafts and the rotating plates, which greatly increases the friction between them, thereby further enhancing the self-locking force of the blade assembly.

[0013] Preferably, a limiting block is provided on the frame body, the limiting block abuts against the frame body and forms a rotating cavity, the rotating end of the blade assembly is rotated in the rotating cavity, and a positioning post extends from the side of the limiting block, and a positioning hole is formed on the drive crank for the positioning post to be inserted. Through the above improvements, the stability of the blade assembly during rotation is ensured by the cooperation between the limiting block and the frame body, and the stability of the drive crank during rotation is also ensured by the positioning post and the positioning hole, thereby making the blade assembly rotate more smoothly.

[0014] Preferably, the frame body has a limiting post, the limiting block has a limiting hole for the limiting post to be inserted, the frame body has a fixing hole, and the limiting block has a connecting hole that is opposite to the fixing hole. Through the above improvements, the limiting post and the limiting hole cooperate to ensure the accuracy of the limiting block's position installation, and the connecting hole and the fixing hole cooperate to lock the limiting block, thereby ensuring the reliability of the limiting block's installation.

[0015] Preferably, the upper blade and the lower blade include a first and a second exterior blade that cover each other, and a blade skeleton disposed between the first and the second exterior blades. The exposed surfaces of the first and the second exterior blades are smooth. The blade skeleton is provided with a plurality of reinforcing ribs, and the blade skeleton is provided with a rotating shaft on both sides. Through the above improvements, the reinforcing ribs of the blades are not visible compared to conventional blades, which improves the aesthetics of the blades and provides strong structural strength to ensure the service life of the blades.

[0016] Preferably, the blade skeleton is welded to the first outer blade, and the second outer blade is snapped onto the blade skeleton. The first outer blade is provided with a plurality of welding tabs, and the blade skeleton is formed with welding grooves for the welding tabs to be inserted. The exposed surfaces of the first and second outer blades are smooth. The blade skeleton is provided with a plurality of reinforcing ribs, and the blade skeleton is provided with rotating shafts on both sides. Through the above improvements, the structural strength of the blade assembly is greatly improved.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] The blade assembly is driven by a linkage assembly to swing relative to each other. The blade assembly includes an upper blade and a lower blade. The linkage assembly includes several riveted connecting rods. The connecting rods are riveted together and connect the upper blade and the lower blade respectively. Because the connecting rods are riveted together, the resistance when the blade rotates is increased. In addition, the locking force of the motor itself can achieve a locking effect. When the blade assembly is in the open or closed state, the connecting rods form a self-locking angle and are supported on the back of the blade assembly, which further enhances the self-locking force of the blade assembly.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0033] like Figure 1-11 As shown, a split-opening motion mechanism for an automotive air intake grille includes a frame body 1, a blade assembly 2 mounted on the air intake end of the frame body 1, a connecting rod assembly 3 that drives the blade assembly 2 to swing relative to each other, and a drive motor 4 that drives the connecting rod assembly 3 to move.

[0034] Specifically, the blade assembly 2 includes an upper blade 1.1 and a lower blade 1.2. The connecting rod assembly 3 includes several connecting rods 1.3, which are riveted together and respectively rivet the upper blade 1.1 and the lower blade 1.2. The upper blade 1.1 and the lower blade 1.2 are driven to swing relative to each other. The drive motor 4 drives the connecting rods 1.3 to move so that the blade assembly 2 has a closed state and an open state. When the blade assembly 2 is in the open state, the connecting rods 1.3 form a self-locking angle and are supported on the back of the blade assembly 2.

[0035] The connecting rods 1.3 are riveted together, and the upper blade 1.1 and the lower blade 1.2 are riveted together. Because the connecting rods 1.3 are riveted together, the resistance when the blades rotate is increased. Combined with the locking force of the motor itself, a locking effect can be achieved. When the blade group 2 is in the open or closed state, the connecting rods 1.3 form a self-locking angle and are supported on the back of the blade group 2, which further enhances the self-locking force of the blade group 2 in the open or closed state and avoids the problem of locking failure.

[0036] like Figures 1 to 7 As shown, in a further explanation of the implementation of the connecting rod 1.3 in this embodiment, the connecting rod 1.3 includes a drive crank 2.1 connected to the drive motor 4, and driven rods 2.2 respectively connected to both ends of the drive crank 2.1. One end of the driven rod 2.2 is riveted to the drive crank 2.1, and the other end is riveted to the upper blade 1.1 or the lower blade 1.2.

[0037] During the oscillation of the blades, the output end of the drive motor 4 drives the drive crank 2.1 to rotate, which in turn drives the driven rods 2.2 at both ends to rotate. The driven rods 2.2 then drive the upper blade 1.1 and the lower blade 1.2 to oscillate relative to each other on the frame body 1. Furthermore, since the drive crank 2.1, driven rods 2.2, upper blade 1.1, and lower blade 1.2 are connected by riveting, their resistance is greatly increased. Combined with the locking force of the motor itself, a locking effect can be achieved.

[0038] Specifically, when the blade group 2 is in the closed or open state, the driven rods 2.2 form a triangular shape and are supported on the back of the blade group 2 to increase the self-locking force of the blade group 2.

[0039] Furthermore, when the blade assembly 2 is in the open state, the driven rods 2.2 have a self-locking angle of approximately 90° to form a right-angled triangle to support the blade assembly 2. The drive crank 2.1 and one driven rod 2.2 form one right-angled side, and the other driven rod 2.2 forms the other right-angled side.

[0040] In addition, when the blade assembly 2 is in the closed state, the drive crank 2.1 and the driven rod 2.2 form a self-locking angle of about 60° to form an equilateral triangle to support the blade assembly 2, thereby greatly improving the support effect of the blade assembly 2. Furthermore, in conjunction with the self-resistance of the riveting of the connecting rod 1.3 and the locking force of the motor, the locking effect of the blade assembly 2 in the open state is greatly improved.

[0041] like Figures 1 to 7 As shown, a further explanation of the riveting between the drive crank 2.1 and the driven rod 2.2 is provided: a shaft 2.3 is inserted between the drive crank 2.1 and the driven rod 2.2 for riveting. A damping washer 2.4 is provided between the shaft 2.3 and the drive crank 2.1, and a damping washer 2.4 is also provided between the drive crank 2.1 and the driven rod 2.2. The damping washer 2.4 can increase the friction between the drive crank 2.1 and the driven rod 2.2, as well as between the shaft 2.3 and the drive crank 2.1, thereby further improving the locking force of the blade assembly 2.

[0042] Preferably, the insert shaft 2.3 is provided with an anti-disengagement snap ring 2.5. The anti-disengagement snap ring 2.5 is set at the bottom of the insert shaft 2.3, thereby ensuring the reliability of the connection between the drive crank 2.1 and the driven rod 2.2, as well as the connection between the driven rod 2.2 and the blade group 2. Furthermore, the anti-disengagement snap ring 2.5 can further increase the friction at the connection between the drive crank 2.1 and the driven rod 2.2 to ensure the self-locking force.

[0043] As a further explanation of the riveting of the driven rod 2.2 to the upper blade 1.1 and the lower blade 1.2, the rotating ends of the upper blade 1.1 and the lower blade 1.2 are engaged with rotating plates 2.6. The rotating plates 2.6 are riveted to the driven rod 2.2 through a plug shaft 2.3. A damping washer 2.4 is provided between the plug shaft 2.3 and the rotating plates 2.6, and a damping washer 2.4 is also provided between the rotating plates 2.6 and the driven rod 2.2.

[0044] The upper blade 1.1 and the lower blade 1.2 are connected to the driven rod 2.2 by a rotating plate 2.6, and a damping washer 2.4 is provided between the insert shaft 2.3 and the rotating plate 2.6, which greatly increases the friction between them, thereby further improving the self-locking force of the blade assembly 2.

[0045] The rotating piece 2.6 has a snap-fit ​​protrusion, and the upper blade 1.1 and lower blade 1.2 have snap-fit ​​grooves for inserting the snap-fit ​​protrusion, thereby achieving a stable connection between the connecting piece and the upper blade 1.1 and lower blade 1.2.

[0046] like Figures 1 to 7As shown, in some other embodiments, a limiting block 3.1 is provided on the frame body 1. The limiting block 3.1 abuts against the frame body 1 and forms a rotating cavity 3.2. The rotating end of the blade assembly 2 is rotated in the rotating cavity 3.2. The stability of the blade assembly 2 during rotation is ensured by the cooperation between the limiting block 3.1 and the frame body 1.

[0047] Furthermore, a positioning post 3.3 extends from the side of the limiting block 3.1, and a positioning hole 3.4 is formed on the drive crank 2.1 for the positioning post 3.3 to be inserted. The positioning post 3.3 and the positioning hole 3.4 simultaneously ensure the stability of the drive crank 2.1 during rotation, thereby making the blade group 2 rotate more smoothly.

[0048] Preferably, a limiting post 4.1 is formed on the frame body 1, a limiting hole 4.2 is formed on the limiting block 3.1 for the limiting post 4.1 to be inserted, and a fixing hole 4.3 is formed on the frame body 1, and a connecting hole 4.4 is formed on the limiting block 3.1 opposite to the fixing hole 4.3.

[0049] The positioning accuracy of the limiting block 3.1 is ensured by the cooperation of the limiting post 4.1 and the limiting hole 4.2, and the limiting block 3.1 is locked by the cooperation of the connecting hole 4.4 and the fixing hole 4.3 to ensure the reliability of the installation of the limiting block 3.1.

[0050] like Figures 8 to 11 As shown, as a further explanation of the embodiment of the blade group 2, the upper blade 1.1 and the lower blade 1.2 include a first outer appearance blade 5.1 and a second outer appearance blade 5.2 that cover each other, and a blade frame 5.7 disposed between the first outer appearance blade 5.1 and the second outer appearance blade 5.2. The exposed surfaces of the first outer appearance blade 5.1 and the second outer appearance blade 5.2 are smoothly disposed. The blade frame 5.7 is provided with a plurality of reinforcing ribs 5.3, and the blade frame 5.7 is provided with a rotating shaft 5.4 on both sides. The rotating shaft 5.4 is connected to the connecting rod 1.3 to realize the swing of the blade group 2. Compared with conventional blades, the reinforcing ribs 5.3 on the blade surface cannot be seen, which improves the aesthetics of the blade and has strong structural strength to ensure the service life of the blade.

[0051] Specifically, the blade frame 5.7 is welded to the first outer blade 5.1, and the second outer blade 5.2 is snapped onto the blade frame 5.7.

[0052] Furthermore, the first outer blade 5.1 is provided with a plurality of welding pieces 5.5, and the blade frame 5.7 is formed with welding grooves 5.6 for the welding pieces 5.5 to be placed in. During the assembly process, the blade frame 5.7 is placed on the first outer blade 5.1, and the welding pieces 5.5 are placed in the welding grooves 5.6. The blade frame 5.7 is then welded to the first outer blade 5.1 using the welding pieces 5.5, thereby ensuring the reliability of the installation of the blade frame 5.7 and significantly improving the structural strength of the blade assembly 2.

[0053] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
