Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive front grilles, and more particularly to an automotive front grille assembly. Background Technology
[0002] The front grille is an important component of a vehicle's front end, playing a crucial role not only in its exterior design but also in its practical function. The front grille is typically located at the front of the car, directly in front of the radiator.
[0003] The front grille protects various components in the engine compartment from direct impacts from stones, debris, and other objects that may be blown up by the road. By design, it allows an appropriate amount of air to flow into the engine compartment to help cool the engine and radiator, thus ensuring that the engine operates within its optimal temperature range. However, while air is introduced through the front grille, it also makes it easy for a lot of dust in the air to enter the engine compartment and other components, accumulating on the parts and affecting the engine compartment's heat dissipation and other functions.
[0004] Therefore, it is necessary to provide a new automotive front grille assembly to solve the aforementioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an automotive front grille assembly.
[0006] The automotive front grille assembly provided by this utility model includes a grille frame and an outer frame. Multiple grille strips are fixed inside the grille frame. Elastic limiting devices are fixed at both ends of the top of the grille frame, and rotating devices are fixed at both ends of the bottom of the grille frame. A filter screen is fixed inside the outer frame, and positioning blocks are fixed at both ends of the top of the outer frame. Positioning grooves are opened on the two positioning blocks. One end of the elastic limiting device can be moved into the positioning groove. Moving devices are fixed at both ends of the bottom of the outer frame. One end of each of the two moving devices can be moved into the two rotating devices respectively. When the end of the moving device is located in the rotating device, the outer frame can rotate.
[0007] Preferably, the rotating device includes a fixed block and a rotating ring. The fixed block is fixed on the grid frame, and a groove is provided at one end of the fixed block. The outer wall of the rotating ring is rotatably connected to the inner wall of the groove of the fixed block, and multiple limiting grooves are provided on the inner wall of the rotating ring.
[0008] Preferably, the moving device includes a vertical plate, a threaded rod, and a plug. The vertical plate is fixed on the outer frame, the threaded rod is threadedly connected to the vertical plate, one end of the threaded rod is fixedly connected to a throttle handle, and the other end of the threaded rod is rotatably connected to a plug. The outer wall of the plug is fixed with multiple limiting strips, which can move into multiple limiting grooves respectively.
[0009] Preferably, the elastic limiting device includes a limiting block, a moving column, a spring, and an extrusion member. The limiting block is fixed on the grid frame, and a receiving groove is provided on the limiting block. The spring is fixed on the bottom wall of the receiving groove. One end of the spring is fixedly connected to the moving column. The end of the moving column away from the spring has an arc-shaped structure, and the size of the arc-shaped structure is adapted to the size of the positioning groove. The spring is sleeved on the outside of the extrusion member, and the extrusion member is used to extrude the moving column.
[0010] Preferably, the extrusion component includes an extrusion column and a threaded bracket. The extrusion column is slidably disposed in an extrusion groove opened at the end of the movable column. One end of the threaded bracket is rotatably connected to the extrusion column, and the other end of the threaded bracket extends out of the outer side of the receiving groove. The threaded bracket is threadedly connected to the limiting block.
[0011] Preferably, a slider is fixed on the outer wall of the extrusion column, and the slider is slidably disposed in a groove opened in the inner wall of the extrusion groove. When one end of the slider is located on the inner side of the groove away from the arc-shaped structure, the moving column can be moved into the receiving groove by extrusion.
[0012] Compared with related technologies, the automotive front grille assembly provided by this utility model has the following beneficial effects:
[0013] The filter effectively blocks dust from the air, making it difficult for dust to enter the car's interior.
[0014] Turning the throttle causes the threaded rod to rotate, aligning the limiting strip with the limiting groove. As the threaded rod rotates, it moves the insert into the rotating ring, thus completing the installation work on both sides of the bottom end of the outer frame. Since the bottom end of the outer frame can be disassembled and rotated, when washing the car, only the top of the outer frame needs to be removed. Then, by rotating the outer frame, the grille strips can be rinsed. The operation is convenient. When the filter screen needs to be replaced, the bottom end of the outer frame can be removed.
[0015] Rotate the outer frame, and the bottom end of the outer frame will press against the arc-shaped structure of the moving column. The end of the moving column will move into the receiving groove. When the outer frame rotates until the arc-shaped structure is directly facing the positioning groove, the end of the moving column will move into the positioning groove under the action of the compressed spring. At this time, the outer frame is supported by the moving columns on both sides, eliminating the need for manual assistance and simplifying the operation. Next, rotate the threaded frame, which will drive the pressing column to move, so that one end of the pressing column is pressed against the bottom wall of the pressing groove, and the arc-shaped structure is pressed against the positioning groove, thereby completing the installation of the outer frame and the filter screen on it.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1-3 ,in, Figure 1 A schematic diagram of the structure of the automotive front grille assembly provided by this utility model; Figure 2 for Figure 1 The diagram shown is a schematic of a structure for removing the filter screen. Figure 3 for Figure 1 A cross-sectional structural schematic diagram of the elastic limiting device shown.
[0022] In the specific implementation process, such as Figures 1-3 As shown, the device includes a grid frame 1 and an outer frame 3. Multiple grid strips 2 are fixed inside the grid frame 1. Elastic limiting devices are fixed at both ends of the top of the grid frame 1. Rotating devices are fixed at both ends of the bottom of the grid frame 1. A filter screen 4 is fixed inside the outer frame 3. Positioning blocks 5 are fixed at both ends of the top of the outer frame 3. Positioning grooves 6 are provided on both positioning blocks 5. One end of the elastic limiting device can be moved into the positioning groove 6. Moving devices are fixed at both ends of the bottom of the outer frame 3. One end of each moving device can be moved into the two rotating devices respectively. When the end of the moving device is located in the rotating device, the outer frame 3 can rotate.
[0023] The rotating device includes a fixed block 7 and a rotating ring 8. The fixed block 7 is fixed on the grid frame 1. A groove is provided at one end of the fixed block 7. The outer wall of the rotating ring 8 is rotatably connected to the inner wall of the groove of the fixed block 7. Multiple limiting grooves 9 are provided on the inner wall of the rotating ring 8. The moving device includes a vertical plate 10, a threaded rod 11, and a plug 12. The vertical plate 10 is fixed on the outer frame 3. The threaded rod 11 is threadedly connected to the vertical plate 10. A handle 13 is fixedly connected to one end of the threaded rod 11, and a plug is rotatably connected to the other end of the threaded rod 11. 12. Multiple limiting strips 14 are fixed on the outer wall of the insert post 12. The multiple limiting strips 14 can be moved into multiple limiting grooves 9 respectively. Rotating the handle 13 causes the threaded rod 11 to rotate, aligning the limiting strips 14 with the limiting grooves 9. When the threaded rod 11 rotates, it causes the insert post 12 to move towards the inside of the rotating ring 8, thereby completing the installation work at the bottom of the outer frame 3. The filter screen 4 can effectively block dust in the air, making it difficult for dust in the air to enter the car interior.
[0024] The elastic limiting device includes a limiting block 15, a moving column 16, a spring 17, and an extrusion member. The limiting block 15 is fixed on the grid frame 1. A receiving groove 18 is provided on the limiting block 15. The spring 17 is fixed on the bottom wall of the receiving groove 18. One end of the spring 17 is fixedly connected to the moving column 16. The end of the moving column 16 away from the spring 17 has an arc-shaped structure. The size of the arc-shaped structure is adapted to the size of the positioning groove 6. The spring 17 is sleeved on the outside of the extrusion member. The extrusion member is used to extrude the moving column 16. The extrusion member includes an extrusion column 19 and a threaded frame 21. The extrusion column 19 is slidably disposed in the extrusion groove 20 opened at the end of the moving column 16. One end of the threaded frame 21 is rotatably connected to the extrusion column 19, and the other end of the threaded frame 21 extends out of the receiving groove. On the outside of the groove 18, and with the threaded frame 21 threadedly connected to the limiting block 15, the outer frame 3 is rotated. The bottom end of the outer frame 3 presses against the arc-shaped structure of the moving column 16. The end of the moving column 16 moves into the receiving groove 18. When the outer frame 3 rotates until the arc-shaped structure is facing the positioning groove 6, the end of the moving column 16 moves into the positioning groove 6 under the action of the compressed spring 17. At this time, the outer frame 3 is supported by the moving columns 16 on both sides, eliminating the need for manual assistance and simplifying the operation. Then, the threaded frame 21 is rotated, and the threaded frame 21 drives the pressing column 19 to move, so that one end of the pressing column 19 is pressed against the bottom wall of the pressing groove 20, and the arc-shaped structure is pressed against the positioning groove 6, thereby completing the installation of the outer frame 3 and the filter screen 4 on it.
[0025] A slider 22 is fixed on the outer wall of the extrusion column 19. The slider 22 is slidably disposed in the groove 23 opened in the inner wall of the extrusion groove 20. When one end of the slider 22 is located inside the groove 23 away from the arc-shaped structure, the moving column 16 can be moved into the receiving groove 18 by extrusion. The slider 22 and the groove 23 used in conjunction with it make it difficult for the extrusion column 19 to detach from the extrusion groove 20.
[0026] The working principle of this utility model is as follows: During installation, the handle 13 is rotated, causing the threaded rod 11 to rotate and align the limiting strip 14 with the limiting groove 9. When the threaded rod 11 rotates, it causes the insert 12 to move inward toward the rotating ring 8, thereby completing the installation of the bottom of the outer frame 3. Then, the outer frame 3 is rotated, and the bottom of the outer frame 3 presses against the arc-shaped structure of the moving column 16. The end of the moving column 16 moves into the receiving groove 18. When the outer frame 3 rotates until the arc-shaped structure is directly facing the positioning groove 6, the end of the moving column 16 moves into the positioning groove 6 under the action of the compressed spring 17. At this time, the outer frame 3 is supported by the moving columns 16 on both sides, eliminating the need for manual assistance and simplifying the operation. Next, the threaded frame 21 is rotated, causing the pressing column 19 to move, so that one end of the pressing column 19 abuts against the bottom wall of the pressing groove 20, and the arc-shaped structure abuts against the positioning groove 6, thereby completing the installation of the outer frame 3 and the filter screen 4 on it.
[0027] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
