Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an anti-folding structure for automotive license plate frames. Background Technology

[0002] Car license plate frames are common accessories used to fix car license plates and protect the edges of the license plates. They are installed at the license plate mounting positions on the front and rear bumpers of a car and must meet the core requirements of not obscuring license plate information and having a stable structure that is not easily damaged.

[0003] The existing vehicle license plate frames have the following technical defects: Poor folding resistance: Most license plate frames use a single plastic or thin metal frame structure, lacking a design to enhance structural strength. When subjected to external impact or compression, the frame is prone to folding and deformation, resulting in license plate displacement, information obstruction, and impact on traffic supervision. Moreover, it is difficult to repair after deformation. Insufficient stability of license plate fixing: Existing license plate frames mostly rely on screws on the top and bottom edges to directly fix the license plate, and lack limiting structures in the left and right directions. After long-term use, the license plate is prone to loosening due to vehicle bumps, and there is even a risk of the license plate separating from the frame. Lack of warning function: When the license plate is maliciously damaged, the user cannot notice it in time, which may easily lead to traffic violation disputes or property damage.

[0004] In view of the shortcomings of the prior art, a folding prevention structure for car license plate frames is provided. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an anti-folding structure for car license plate frames.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model relates to an anti-folding structure for a car license plate frame, comprising a frame body, an internal mounting cavity for mounting the license plate, an insertion port at the bottom of the frame body, a display window on the front panel of the frame body, mounting screw holes on the upper and lower edges of the frame body, a honeycomb-shaped window on the back panel of the frame body, multiple screws threaded through both ends of the back panel of the frame body, a spring mounted on the end of each screw facing the mounting cavity, snap-fit ​​grooves at both the upper and lower ends of the back panel of the frame body, ratchet bars on both sides of the inner wall of the snap-fit ​​grooves, a pressing strip movably engaging inside the snap-fit ​​grooves, and teeth on both ends of the pressing strip engaging with the ratchet bars.

[0007] As a preferred embodiment of this utility model, micro switches are embedded in the left and right ends of the inner side of the back panel of the frame body, the micro switches are covered with elastic arch plates, and buzzers are installed on both sides of the outer side of the frame body.

The buzzer has a button battery mounting slot inside, and a battery replacement window communicating with the battery mounting slot is opened on the side of the buzzer. The button battery powers the buzzer and the micro switch.

[0009] As a preferred embodiment of this utility model, a rubber layer is bonded to the inner surface of the extrusion strip facing the mounting cavity, and the thickness of the rubber layer is 1-2mm.

[0010] As a preferred technical solution of this utility model, the outer surface of the extrusion strip away from the mounting cavity is provided with a peeling opening along the length direction for easy disassembly. The peeling opening is a V-shaped groove or a rectangular groove, and the depth of the peeling opening is 1 / 3 to 1 / 2 of the thickness of the extrusion strip.

[0011] As a preferred embodiment of this utility model, the honeycomb unit of the honeycomb window is a regular hexagonal structure, and the area of ​​the honeycomb window accounts for 40%-60% of the area of ​​the back panel of the frame body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the honeycomb-shaped window on the back panel of the frame body to disperse stress through the honeycomb structure, significantly enhancing the frame's resistance to bending, effectively preventing folding deformation caused by external forces, and extending the service life of the license plate frame.

[0013] This utility model achieves all-round positioning of the license plate by using the elastic compression of springs on the left and right screws and the fixed compression of upper and lower compression strips to form a double fixing structure.

[0014] This utility model uses an alarm system composed of a micro switch, an elastic arch plate and a buzzer to promptly issue a warning signal when a license plate is maliciously damaged, thereby reducing the risk of property loss. In this utility model, the license plate is inserted through the bottom insertion port and fixed by an adjustable screw and extrusion strip, making installation simple; the peeling port design of the extrusion strip facilitates later maintenance.

[0017] In the attached diagram, all identical reference numerals refer to the same components.

[0018] Example 1 like Figure 1-7 As shown, this utility model provides an anti-folding structure for a car license plate frame, including a frame body 1. The frame body 1 has an installation cavity for installing the license plate inside. The bottom end of the frame body 1 has an insertion port. The front panel of the frame body 1 has a display window 5. The upper and lower sides of the frame body 1 are provided with mating screw holes 6. The back panel of the frame body 1 has a honeycomb window 7. Multiple screws 8 are threaded through both ends of the back panel of the frame body 1. A spring 9 is installed at the end of the screw 8 facing the installation cavity. The upper and lower ends of the back panel of the frame body 1 have snap-fit ​​grooves 10. The inner walls of the snap-fit ​​grooves 10 are provided with ratchet bars 11 on both sides. An extrusion bar 12 is movably snapped into the inside of the snap-fit ​​grooves 10. Both ends of the extrusion bar 12 are provided with teeth 13, and the teeth 13 are snapped into the ratchet bars 11.

[0019] Furthermore, micro switches 2 are embedded in the left and right ends of the inner side of the back panel of the frame body 1, and the micro switches 2 are covered with elastic arch plates 3. Buzzers 4 are installed on both sides of the outer side of the frame body 1.

[0020] Furthermore, the micro switch 2 is connected in series with the buzzer 4 via a wire to form an alarm circuit. The buzzer 4 has a button battery mounting slot inside, and a battery replacement window connected to the battery mounting slot is opened on the side of the buzzer 4. The button battery powers the buzzer 4 and the micro switch 2.

[0021] Furthermore, a rubber layer is bonded to the inner surface of the extrusion strip 12 facing the mounting cavity, and the thickness of the rubber layer is 1-2 mm.

[0022] Furthermore, the outer surface of the extrusion strip 12 away from the mounting cavity is provided with a peeling opening along its length for easy disassembly. The peeling opening is a V-shaped groove or a rectangular groove, and the depth of the peeling opening is 1 / 3 to 1 / 2 of the thickness of the extrusion strip 12.

[0023] Furthermore, the honeycomb window 7 has a regular hexagonal structure for its honeycomb unit, and the area of ​​the honeycomb window 7 accounts for 40%-60% of the area of ​​the back panel of the frame body 1.

[0024] Specifically, the frame body 1 is made of ABS engineering plastic, which has lightweight and high strength characteristics; its internal mounting cavity size is adapted to standard small car license plates; the display window 5 on the front panel ensures that the license plate information is fully exposed.

[0025] Two M6 screw holes 6 are provided at intervals on the upper and lower edges of the frame body 1 to fit the screws of the car license plate mounting position; the honeycomb window 7 of the back panel accounts for 50% of the area of ​​the back panel and is integrally molded by injection molding to enhance the bending resistance of the frame body 1.

[0026] Four screws 8 are set at each of the left and right ends of the back panel of the frame body 1. The screws 8 are of M4 specification and have a slot at the end. The spring 9 is a stainless steel compression spring with a natural length of 10mm. Rotating the screws 8 can push the spring 9 to move into the mounting cavity until the spring 9 contacts the side of the license plate and generates a squeezing force to achieve elastic limiting.

[0027] The ratchet 11 in the snap-fit ​​grooves 10 at both ends of the back panel of the frame body 1 has a tooth pitch of 2mm and a tooth height of 2mm; the extrusion strip 12 is made of PP plastic and its length is adapted to the snap-fit ​​groove 10. The teeth 13 at both ends of the extrusion strip 12 engage with the ratchet 11 in one direction; the rubber layer on the inner side of the extrusion strip 12 is 1.5mm thick and has a 0.4mm high diamond anti-slip texture on the surface; the peeling opening on the outer surface is a V-shaped groove with a depth of 1mm, which facilitates prying the extrusion strip 12 during disassembly.

[0028] The elastic arch 3 is made of PET material and is arc-shaped in its natural state. When squeezed, it adheres to the micro switch 2 to close it. The buzzer 4 is powered by a CR2032 button battery. When the license plate is bent, the elastic arch 3 deforms and squeezes the micro switch 2, and the buzzer 4 emits an alarm sound.

[0029] Installation steps: Insert the license plate into the mounting cavity through the insertion port at the bottom of the frame body 1, ensuring that the front of the license plate is aligned with the display window 5 and that the upper and lower edges of the license plate are flush with the upper and lower edges of the frame body 1.

[0030] Move the extrusion strip 12 toward the mounting cavity until the rubber layer is in close contact with the middle of the upper and lower edges of the license plate. At this point, the toothed pattern 13 engages with the ratchet 11, and the extrusion strip 12 cannot retract.

[0031] Use a flathead screwdriver to rotate the screws 8 at both ends of the back panel of the frame body 1, pushing the spring 9 to move towards the license plate until you feel slight resistance and then stop rotating.

[0032] After installation, pry open the two sides of the license plate to squeeze the elastic arch plate 3. If the buzzer 4 sounds an alarm, it means that the alarm system is working properly.

[0033] Finally, align the frame body 1 with the license plate mounting position, and use screws to pass through the mating mounting screw holes 6 to fix the frame body 1 to the car.

[0034] When the alarm sound of buzzer 4 weakens, open the battery replacement window and replace the button battery. If the license plate needs to be removed, use a tool to pry open the peeling opening of the extrusion strip 12 to separate the teeth 13 from the ratchet 11. After removing the extrusion strip 12, rotate the screw 8 in the opposite direction to remove the license plate from the insertion port.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
