Description

Technical Field

[0001] This utility model belongs to the field of automotive grille technology, specifically relating to a paint-free automotive grille. Background Technology

[0002] Paint-free automotive grilles are a type of automotive grille material that utilizes paint-free technology. Their core feature is that through injection molding, they achieve high gloss, weather resistance, and environmental friendliness without traditional painting. Paint-free automotive grilles are an automotive exterior component that combines environmental friendliness, high performance, and high gloss, and are widely used in the automotive, home appliance, and other fields.

[0003] In existing car grille designs, filters are installed within the grille to prevent lint from entering the engine compartment. However, over time, a layer of lint accumulates on these filters, especially in northern regions during May when willow catkins are abundant. If not cleaned promptly, this can directly impact engine compartment cooling. Currently, most car grilles are designed to be wider at the top and narrower at the bottom, making it impossible to pull the filters directly from the bottom. Pulling them from the top requires opening the hood, making filter removal particularly cumbersome and inefficient for cleaning.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a paint-free automotive grille.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a paint-free automotive grille, which can solve the problem of inconvenient disassembly of existing automotive grille filters.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A paint-free automotive grille includes: an outer frame, a grille, a mounting groove, and a filter mechanism.

[0009] The inner wall of the mounting frame is carved with stepped grooves for the grid and filter screen from the outside to the inside. The grid is installed in the grid groove. The mounting groove is carved into the bottom wall of the filter screen groove. The filter screen mechanism is installed in the filter screen groove and includes: a pair of side filters, a middle filter, two pairs of first slide rails, a pair of second slide rails, two pairs of locking rods, and a locking plate. The pair of side filters are respectively located at both ends of the filter screen groove, and the middle filter is installed between the pair of side filters and is locked to the pair of side filters. Both pairs of first slide rails are fixed to the mounting frame, and both pairs of second slide rails are fixed to the upper end of the mounting frame. The pair of second slide rails are respectively connected to the top ends of the two pairs of first slide rails. The pair of locking rods are respectively locked to the top of the pair of side filters, and a pair of fixed shafts are fixed on the locking rods. The pair of fixed shafts slide in the pair of first and second slide rails. The locking plate is fixed to the bottom of the middle filter, and the bottom of the mounting frame is carved with a locking plate groove adapted to the locking plate.

[0010] In one embodiment of this utility model, multiple pairs of bolt holes are drilled on both the side wall of the grille and the mounting frame, and bolts are threaded into each of the multiple pairs of bolt holes. By tightening the bolts into the bolt holes, the mounting frame and the grille are fixed together.

[0011] In one embodiment of this utility model, a plurality of ear plates are fixed on the outer wall of the mounting frame, and the ear plates are used to fix the mounting frame to the vehicle frame.

[0012] In one embodiment of this utility model, a first snap-fit ​​strip is fixed on each of the two side walls of the intermediate filter screen, and a first snap-fit ​​groove is chiseled on the side wall of each pair of side filters near the intermediate filter screen. The first snap-fit ​​strip is snapped into the first snap-fit ​​groove. The intermediate filter screen and the pair of side filters are snapped together by the first snap-fit ​​strip in the first snap-fit ​​groove, thereby achieving mutual snap-fit.

[0013] In one embodiment of this utility model, each pair of first snap-fit ​​slots has a flared inlet at the bottom, and each pair of first snap-fit ​​strips has a tapered plug fixed at the top. By providing the tapered plug and the flared inlet, the first snap-fit ​​strip can more easily snap into the first snap-fit ​​slot when the middle filter is inserted upward between the pair of side filters.

[0014] In one embodiment of this utility model, a limiting head is fixed to one end of the fixed shaft located outside the mounting frame, and a pulley is mounted on the fixed shaft. The limiting head is used to limit the locking rod, preventing it from disengaging from a pair of first or second slide tracks. The pulley is used to reduce the frictional force of the fixed shaft sliding in the pair of first or second slide tracks.

[0015] In one embodiment of this utility model, a second snap-fit ​​strip is fixed to the top of the side filter screen, and a second snap-fit ​​groove is chiseled on the snap-fit ​​rod, with the second snap-fit ​​strip snapping into the second snap-fit ​​groove. The snap-fit ​​rod is snapped into the second snap-fit ​​groove via the second snap-fit ​​strip, thereby achieving snap-fit ​​with the side filter screen.

[0016] In one embodiment of this utility model, a pair of grooves are chiseled on the snap-fit ​​rod, and a rotating shaft is fixed in each of the grooves. A rotating plate is rotatably mounted on the rotating shaft, and a torsion spring is also installed on the rotating shaft. A snap-fit ​​head is fixed at the end of the rotating plate away from the rotating shaft, and a snap-fit ​​groove corresponding to the snap-fit ​​head is chiseled on the second snap-fit ​​strip. When the side filter pushes the snap-fit ​​rod to slide upward along a pair of first slides into the second slide, the top wall of the snap-fit ​​rod contacts the upper top wall of the filter groove, thereby pushing the rotating plate to rotate about the rotating shaft in the direction of the side filter, so that the snap-fit ​​head is locked in the snap-fit ​​groove, and the second snap-fit ​​strip is locked in the second snap-fit ​​groove. Thus, when the side filter slides left and right, the side filter drives the snap-fit ​​rod to slide on the second slide. When the snap-fit ​​rod slides down from the second slide into a pair of first slides, the spring force of the torsion spring causes the rotating plate to rotate upward, thereby moving the snap-fit ​​head out of the snap-fit ​​groove, thus not affecting the removal of the side filter from the snap-fit ​​rod.

[0017] In one embodiment of this utility model, a pair of screws are threadedly connected to the card plate, and a pair of locking holes corresponding to the screws are drilled on the mounting frame. A knob head is fixed to one end of the screw outside the card plate. The screw is rotated by the knob head, causing the screw to be inserted into the locking hole, thereby fixing the card plate and thus fixing the intermediate filter screen.

[0018] Compared with the prior art, the paint-free car grille of this utility model, through its related structural design, effectively facilitates the disassembly of the car grille filter screen, thereby improving the cleaning efficiency of the filter screen. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0029] like Figures 1 to 6 As shown, a paint-free automotive grille according to one embodiment of the present invention includes: an outer frame 1, a grille 101, a mounting groove 107, and a filter mechanism 2.

[0030] like Figures 1 to 6As shown, the inner wall of the mounting frame 1 is steppedly carved with grille grooves 103 and filter screen grooves 104 from the outside to the inside. Grilles 101 are installed in the grille grooves 103. Mounting grooves 107 are carved into the bottom wall of the filter screen grooves 104. A filter screen mechanism 2 is installed in the filter screen grooves 104. The filter screen mechanism 2 includes: a pair of side filters 201, a middle filter 202, two pairs of first slide rails 203, a pair of second slide rails 204, two pairs of locking rods 205, and a locking plate 220. A pair of side filters 201 are respectively located at both ends of the filter screen grooves 104. The middle filter 202 is installed between the pair of side filters 201 and is locked to the pair of side filters 201. Both pairs of first slide rails 203 are fixed to the mounting frame 1, and both pairs of second slide rails 204 are fixed to the upper end of the mounting frame 1. The pair of second slide rails 204 are respectively connected to the top ends of the two pairs of first slide rails 203. A pair of snap-fit ​​rods 205 are snapped onto the top of a pair of side filter screens 201 respectively. A pair of fixed shafts 212 are fixed on the snap-fit ​​rods 205, and the pair of fixed shafts 212 slide in a pair of first slide rails 203 and second slide rails 204. The snap-fit ​​plate 220 is fixed to the bottom of the middle filter screen 202, and the bottom of the mounting frame 1 is chiseled with a snap-fit ​​plate groove 224 that matches the snap-fit ​​plate 220.

[0031] In use, when it is necessary to install a pair of side filters 201 and a middle filter 202 into the filter groove 104, first take out one of the side filters 201, insert the top of the side filter 201 into the mounting groove 107, and engage it with the locking rod 205 on the same side of the side filter 201. Then push the side filter 201 upward into the filter groove 104. The side filter 201 drives the locking rod 205 to slide upward along the trajectory of a pair of first slides 203. When the locking rod 205 slides into the second slide 204, move the side filter 201 to one side, so that the side filter 201 moves to one end of the filter groove 104. Then install the other side filter 201. Then, insert the intermediate filter 202 upward from the mounting slot 107 into the filter slot 104, and make its two ends respectively snap together with a pair of side filters 201, and then snap the clip 220 into the clip slot 224 to complete the installation.

[0032] When it is necessary to disassemble a pair of side filters 201 and a middle filter 202, first pull the middle filter 202 out of the pair of side filters 201, then slide the side filters 201 towards the middle so that the locking rod 205 slides to a pair of first slides 203. Then move the side filters 201 downwards along the track of the pair of first slides 203, pull out the side filters 201, and remove the top of the side filters 201 from the locking rod 205. Then clean the pair of side filters 201 and the middle filter 202.

[0033] like Figures 1 to 6As shown, multiple pairs of bolt holes 105 are drilled on the side wall of the grille 101 and on the mounting frame 1, and bolts 106 are threaded into each pair of bolt holes 105. By tightening the bolts 106 into the bolt holes 105, the mounting frame 1 and the grille 101 are fixed together. Multiple ear plates 102 are fixed on the outer side wall of the mounting frame 1, and the ear plates 102 are used to fix the mounting frame 1 to the vehicle frame.

[0034] like Figures 1 to 6 As shown, first snap-fit ​​strips 206 are fixed on both sides of the intermediate filter 202, and first snap-fit ​​grooves 207 are carved on the side walls of the pair of side filters 201 near the intermediate filter 202. The first snap-fit ​​strips 206 snap into the first snap-fit ​​grooves 207. The intermediate filter 202 and the pair of side filters 201 are snapped together by the first snap-fit ​​strips 206 in the first snap-fit ​​grooves 207, thus achieving mutual snap-fit. The bottom of the pair of first snap-fit ​​grooves 207 is carved with flared insertion holes 209, and the top of the pair of first snap-fit ​​strips 206 is fixed with constricting plugs 208. By providing constricting plugs 208 and flared insertion holes 209, when the intermediate filter 202 is inserted upward between the pair of side filters 201, the first snap-fit ​​strips 206 can more easily snap into the first snap-fit ​​grooves 207.

[0035] like Figures 1 to 6 As shown, a limiting head 213 is fixed to one end of the fixed shaft 212 located outside the mounting frame 1, and a pulley 214 is mounted on the fixed shaft 212. The limiting head 213 is used to limit the locking rod 205, preventing it from detaching from the pair of first slide rails 203 or second slide rails 204. The pulley 214 is used to reduce the friction of the fixed shaft 212 sliding in the pair of first slide rails 203 or second slide rails 204. A second locking strip 210 is fixed to the top of the side filter screen 201, and a second locking groove 211 is cut into the locking rod 205. The second locking strip 210 is engaged in the second locking groove 211. The locking rod 205 is engaged in the second locking groove 211 through the second locking strip 210, thereby achieving engagement with the side filter screen 201.

[0036] like Figures 1 to 6As shown, a pair of grooves are carved into the snap-fit ​​rod 205, and a rotating shaft 216 is fixed in each groove. A rotating plate 215 is rotatably mounted on the rotating shaft 216, and a torsion spring 217 is also installed on the rotating shaft 216. A snap-fit ​​head 218 is fixed to the end of the rotating plate 215 away from the rotating shaft 216, and a snap-fit ​​groove 219 corresponding to the snap-fit ​​head 218 is carved into the second snap-fit ​​strip 210. When the side filter 201 pushes the snap-fit ​​rod 205 to slide upward along a pair of first slides 203 into the second slide 204, the top wall of the snap-fit ​​rod 205 contacts the upper top wall of the filter groove 104, thereby pushing the rotating plate 215 to rotate about the rotating shaft 216 in the direction of the side filter 201, so that the snap-fit ​​head 218 is engaged in the snap-fit ​​groove 219, and the second snap-fit ​​strip 210 is engaged in the second snap-fit ​​groove 211. Thus, when the side filter 201 slides left and right, it causes the locking rod 205 to slide on the second slide rail 204. When the locking rod 205 slides down from the second slide rail 204 into a pair of first slide rails 203, the spring force of the torsion spring 217 causes the rotating plate 215 to rotate upward, thereby causing the locking head 218 to move out of the locking slot 219, thus not affecting the removal of the side filter 201 from the locking rod 205.

[0037] like Figures 1 to 6 As shown, a pair of screws 221 are threaded onto the clamping plate 220. A pair of locking holes 223 corresponding to the screws 221 are drilled on the mounting frame 1. A knob head 222 is fixed to one end of the screw 221 outside the clamping plate 220. The screw 221 is rotated by the knob head 222, causing the screw 221 to be inserted into the locking hole 223, thereby fixing the clamping plate 220 and thus fixing the intermediate filter screen 202.

[0038] Working principle: When it is necessary to install a pair of side filters 201 and a middle filter 202 into the filter groove 104, firstly, take out one of the side filters 201, insert the top of the side filter 201 into the mounting groove 107, and insert the second snap-fit ​​strip 210 into the second snap-fit ​​groove 211 on the snap-fit ​​rod 205 from one side of the side filter 201, thereby snapping the side filter 201 and the snap-fit ​​rod 205 together. Then, push the side filter 201 upward into the filter groove 104, and the side filter 201 drives the snap-fit ​​rod 205 to slide upward along the trajectory of a pair of first slides 203.

[0039] When the locking rod 205 slides into the second slide rail 204, the top wall of the locking rod 205 contacts the upper top wall of the filter screen groove 104, thereby pushing the rotating plate 215 to rotate about the axis of the rotating shaft 216 in the direction of the side filter screen 201, so that the locking head 218 is locked in the locking groove 219, and the second locking strip 210 is locked in the second locking groove 211. Thus, when the side filter screen 201 is slid left and right, the side filter screen 201 drives the locking rod 205 to slide on the second slide rail 204. Move the side filter screen 201 to one end of the filter screen groove 104, and then install the other side filter screen 201. Then insert the middle filter screen 202 upward from the mounting groove 107 into the filter screen groove 104, and make the first locking strips 206 at both ends lock into the first locking grooves 207 on the side filter screen 201 respectively, and lock the locking plate 220 into the locking plate groove 224. Then, the screw 221 is rotated by the knob head 222, so that the screw 221 is inserted into the locking hole 223, thereby fixing the card plate 220 and the intermediate filter screen 202.

[0040] When it is necessary to disassemble a pair of side filters 201 and a middle filter 202, first rotate the screw 221 out of the locking hole 223, then pull the middle filter 202 out of the pair of side filters 201, and then slide the side filters 201 towards the middle, so that the locking rod 205 slides to a pair of first slides 203, and then move the side filters 201 downwards along the trajectory of the pair of first slides 203. When the locking rod 205 slides down from the second slide 204 into the pair of first slides 203, the spring force of the torsion spring 217 causes the rotating plate 215 to rotate upwards, so that the locking head 218 moves out of the locking slot 219, thus not affecting the removal of the side filters 201 from the locking rod 205. Pull out the side filter 201 and remove the top of the side filter 201 from the snap-fit ​​rod 205. Then clean the pair of side filters 201 and the middle filter 202.
