[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] refer to Figures 1-10 The illustrated automotive grille trim snap-fit ​​structure includes a grille frame 2, a safety frame 1 on one side of the grille frame 2, an air baffle 3 inside the grille frame 2, mounting clips 6 on both sides of the grille frame 2, and a fixing slot 7 inside the mounting clip 6, with a snap-fit ​​component 4 inside the fixing slot 7 for fixing the grille frame 2 to the vehicle frame.

[0036] It is worth noting that the user installs the grille frame 2 at the front of the car using the snap-fit ​​component 4. The air deflector 3 serves to ventilate and block objects, while the safety frame 1 protects the grille frame 2. During installation, the snap-fit ​​component 4 is inserted into the frame. The snap-fit ​​component 4 adopts a flexible installation method. During installation, the user only needs to align the snap-fit ​​component and insert it into the mounting hole of the frame. Then, the plug inside the snap-fit ​​component protrudes and abuts against the mounting hole, thereby fixing the entire snap-fit ​​structure in the mounting hole of the frame. The overall fixing method of the snap-fit ​​component does not require force to insert or pull, and will not damage the car frame. The installation and removal methods are also simple and do not require brute force, avoiding scratches to the paint on the car surface.

[0037] The snap-fit ​​assembly 4 includes a snap-fit ​​plate 42 that is inserted into the frame for fixation. The snap-fit ​​plate 42 has a placement groove 419 inside. Two diagonal rods 421 are provided inside the placement groove 419. The outer surfaces of the two diagonal rods 421 are slidably mounted with protrusions 49. The upper and lower sides of the outer surface of the snap-fit ​​plate 42 are provided with protrusions 422 that communicate with the inside of the placement groove 419. The protrusions 49 correspond one-to-one with the positions of the two protrusions 422.

[0038] The interior of the placement slot 419 is provided with a pusher 418. Two symmetrical springs 424 are provided on one side of the pusher 418. A pull wire 415 is provided on one side of the pusher 418, and a locking block 48 is tied to one end of the pull wire 415.

[0039] When the user needs to fix the grille frame 2 to the vehicle body, first insert the snap-fit ​​plate 42 into the mounting hole on the frame. Because the snap-fit ​​plate 42 has an arc shape of the letter "S", the user needs to slightly swing the grille frame 2 according to the shape of the snap-fit ​​plate 42 so that the snap-fit ​​plate 42 can be smoothly inserted into the mounting hole on the frame.

[0040] After the snap-fit ​​plate 42 is fully inserted into the mounting hole, the user pulls the snap-fit ​​block 48, which drives the push post 418 to compress the spring 424 through the pull wire 415. Because the push post 418 has arc grooves on both sides that fit the surface of the protrusion 49, and the inclination angles of the two inclined rods 421 are opposite, when the push post 418 moves, it will abut against the two protrusions 49 and slide on the inclined rods 421, causing the two protrusions 49 to slide out of the protrusion 422. As the protrusions 49 slide out, they will abut against the mounting hole of the frame. Because the mounting hole of the frame has a groove that matches the protrusion 49, it can ensure that the snap-fit ​​plate 42 is locked in the mounting hole.

[0041] When the snap-fit ​​plate 42 needs to be removed, simply release the spring 424 of the pull wire 415. The spring 424 will push the push post 418 back to its original position. After the two protrusions 49 are no longer subjected to the squeezing force of the push post 418, they will slide into the placement groove 419 when the snap-fit ​​plate 42 is pulled.

[0042] One end of the snap-fit ​​plate 42 is provided with a fixing plate 41 that is adsorbed onto the grid frame 2, and the upper part of the fixing plate 41 is provided with a connecting plate 43 that is inserted into the fixing slot 7 and fixedly connected to the mounting clip 6. The connecting plate 43 has a sliding groove 44, a wire drawing groove 413 and a wire groove 411 inside. The wire groove 411 passes through the fixing plate 41 and the snap-fit ​​plate 42 and communicates with the interior of the placement slot 419. The wire drawing groove 413 communicates with the interior of the sliding groove 44. A snap-fit ​​groove 414 is provided on one side of the top of the connecting plate 43, and a rectangular hole communicating with the interior of the sliding groove 44 is provided on one side of the connecting plate 43.

[0043] A support column 412 is provided on the upper part of the inner wall of the slide 44. A support rod 46 is rotatably installed on the outer surface of the support column 412. One end of the support rod 46 is rotatably connected to a connecting rod 45, and the connecting rod 45 is slidably installed inside the slide 44. A support spring 47 is provided between the support rod 46 and the connecting rod 45, and the support spring 47 is located inside the slide 44. One end of the steel wire 416 is fixedly connected to the connecting rod 45.

[0044] It is worth noting that when the aforementioned pull block 48 moves the wire 415, it will also move the steel wire 416. The steel wire 416 will pull the connecting rod 45 to slide inside the slide groove 44. As the slide groove 44 slides and compresses the support spring 47 to contract, it will also drive the support rod 46 to rotate on the outer surface of the support column 412. The rotation of the support rod 46 and the connecting rod 45 will cause the support rod 46 and the connecting rod 45 to rotate into a letter "V" shape. After rotation, the support rod 46 and the connecting rod 45 will be locked in the mounting hole set inside the frame. The support rod 46 and the connecting rod 45 act as a pin, thereby ensuring that the installed grille frame 2 will be firmly fixed on the frame.

[0045] The wire drawing 415 is located inside the wire groove 411. The wire drawing groove 413 is provided with a steel wire 416, and the steel wire 416 is connected to the wire drawing 415. The locking block 48 is engaged with the locking groove 414.

[0046] In order to prevent the pulled wire 415 from retracting after being pulled out, when the user pulls the locking block 48 to pull out the wire 415, the user can insert the locking block 48 into the locking slot 414 to fix the length of the pulled wire 415 after it is pulled out.

[0047] A method for assembling a snap-fit ​​structure for automotive grille trim, the specific assembly steps are as follows:

[0048] Step 1: When assembling the car grille trim, screws are used to install the safety frame 1 onto the grille frame 2. Then, the connecting plate 43 is inserted into the fixing slot 7 and fixed with bolts. When installing the connecting plate 43, the fixing plate 41 must be tightly fitted to the grille frame 2.

[0049] The shape of the fixing plate 41 is designed based on the shape of the grid frame 2, so that there will be no abruptness when fixing the fixing plate 41.

[0050] Step 2: After the connecting plate 43 is firmly fixed, align the snap-fit ​​plate 42 with the mounting slot of the frame and forcefully insert the snap-fit ​​plate 42 into the mounting slot of the frame. Because the snap-fit ​​plate 42 is in the shape of the letter "S", when assembling the car grille trim, it is necessary to adjust the tilt angle of the car grille trim according to the curvature of the snap-fit ​​plate 42 so that the snap-fit ​​plate 42 can be fully inserted into the frame.

[0051] The snap-fit ​​plate 42 is made of carbon material, which has good flexibility and strength. In addition, the grid frame 2 itself is made of lightweight carbon fiber material, so not much weight is applied to the snap-fit ​​plate 42 during assembly.

[0052] Step 3: After the user fully inserts the snap-fit ​​plate 42 into the fixed part slot 7, the user pulls the snap-fit ​​block 48. The snap-fit ​​block 48 pulls the push post 418 through the pull wire 415 to slide inside the placement slot 419. As the placement slot 419 slides, it will squeeze the protrusion 49 out of the protrusion 422. After the protrusion 49 out of the protrusion 422, it will abut against the frame, thereby locking the snap-fit ​​plate 42 in the frame.

[0053] The snap-fit ​​plate 42 adopts a pin-type snap-fit ​​structure, but it has two fixing methods. Inserting the snap-fit ​​plate 42 into the mounting frame of the vehicle frame can play a preliminary fixing role. The protrusion of the protrusion 49 into the protrusion 422 to fill the mounting hole of the vehicle frame is to fix the snap-fit ​​plate 42 of the first pin method again, so as to ensure that the fixed snap-fit ​​plate 42 will not easily fall off. Moreover, this splicing fixing method will not scratch the paint on the surface of the car during installation.

[0054] Step 4: When the user pulls the locking block 48 to move the wire 415, it will also move the steel wire 416. The steel wire 416 pulls the connecting rod 45 to slide inside the slide groove 44. While the connecting rod 45 slides, it compresses the support spring 47 to retract. While the connecting rod 45 slides, it drives the support rod 46 to rotate, so that the connecting rod 45 and the support rod 46 are combined into a letter "V" shape and locked in the frame. Then the user locks the locking block 48 in the locking groove 414 to maintain the distance that the wire 415 is pulled out.

[0055] It is worth noting that the rotation of the support rod 46 and the connecting rod 45 will cause the support rod 46 and the connecting rod 45 to rotate into a letter "V" shape. After rotation, the support rod 46 and the connecting rod 45 will be locked into the mounting holes set inside the frame. The support rod 46 and the connecting rod 45 act as a pin, thereby ensuring that the installed grille frame 2 is firmly fixed to the frame.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
