Description

Technical Field

[0001] This utility model belongs to the field of horn cover technology, specifically relating to an easy-to-replace car horn cover. Background Technology

[0002] As a crucial protective component for car horns, the horn cover's core function is to cover the horn's exterior, creating a physical protective barrier that effectively prevents direct damage to the horn from external factors. This includes preventing accidental tool contact during routine maintenance, thus avoiding punctures and scratches to the horn's outer shell and ensuring the horn's normal sound production function and lifespan.

[0003] However, most car horn covers on the market are currently fixed with glue. While this method is simple to install and provides a stable initial hold, it creates significant problems for later maintenance and replacement. When a horn malfunctions and needs repair or replacement, repair personnel can only use tools such as flathead screwdrivers and pry tools to forcibly wed one end of the tool into the gap between the horn cover and the car body, and then use the car body or surrounding parts of the horn as fulcrums to pry it apart using leverage.

[0004] This disassembly method can easily damage the car body and surrounding components. Because leverage relies on a fulcrum, which often acts directly on the body panels or adjacent plastic trim, the fulcrum experiences significant localized pressure during prying, easily scratching the paint. Furthermore, the existing speaker covers have smooth outer walls and lack a load-bearing structure, making disassembly very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an easily replaceable car horn cover, aiming to solve the problem that when construction workers of varying heights attempt to pass through turnstiles for facial recognition, a significant height difference often arises due to the varying vertical distance between the device and the person's face. This height difference may prevent the camera from accurately capturing and clearly identifying the facial features of all individuals, especially when the face deviates from the optimal recognition area, resulting in a significant reduction in recognition accuracy and efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car horn cover that is easy to replace, comprising an outer frame, a set of through holes being provided on the outer wall of the outer frame, and an inclined groove being provided on the surface of each side of the outer frame, wherein a pull handle is respectively engaged inside the groove.

[0007] Each of the handles has a docking block integrally connected to one end. A protrusion is movably installed on each side of the docking block. The protrusion is movably engaged in the docking hole on the inner wall of the groove. A connecting post is fixedly installed on one end of each of the two protrusions. A cam is movably arranged between the two connecting posts. One side of the cam is fixedly connected to one end of a rotating rod. The rotating rod movably passes through the outer wall of one side of the docking block and is connected to the rotating rod.

[0008] In order to allow the protrusion to retract into the through groove when squeezed, as a car horn cover that is easy to replace according to this utility model, preferably, the center end of the docking block is provided with a through groove, and the inner diameter of the through groove is adapted to the maximum diameter of the protrusion.

[0009] In order to make the two protrusions set on the mating block, as a car horn cover that is easy to replace according to this utility model, preferably, the end of the connecting post away from the protrusion is fixedly connected to the outer wall of the center end of the limiting plate, and the other side of the outer wall of the center end of the limiting plate is fixedly connected to an end head.

[0010] The end is a semi-circular structure, with one end of each end in contact with the outer wall of the cam, and the outer wall of the limiting plate in contact with the inner wall of the through groove.

[0011] Two springs are symmetrically installed between the two limiting discs.

[0012] In order to confine the rotating rod within the docking block, as a car horn cover that is easy to replace according to this utility model, preferably, a positioning plate is fixedly sleeved at the center end of the rotating rod, and the positioning plate is movably installed inside the docking block, so that the rotating rod and the docking block form a positioning and movable docking through the positioning plate.

[0013] In order to enable the cam to rotate smoothly in the mating block, as a car horn cover that is easy to replace according to this utility model, preferably, the cam is located at the center end of the through groove, and the maximum diameter of the cam is smaller than the inner diameter of the through groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When it is necessary to remove the outer frame from the car's horn opening, rotate and press one end of the mating block into the groove. This will cause the other end of the mating block to pry up from the groove, allowing the disassembly personnel to hold both mating blocks and pull them outwards.

[0016] Additionally, when pulling the connecting blocks, the cam needs to be adjusted to a vertical position between the two ends by rotating the rod, thus ensuring the protrusion is firmly set in the groove. Pulling the two connecting blocks pulls the outer frame through the groove, allowing for effective tension on the outer frame during disassembly, thereby improving the ease of disassembly. Furthermore, the two connecting blocks increase the force-bearing structure during disassembly, eliminating the need for lever structures to lift the frame and reducing damage to the vehicle.

[0023] 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.

[0024] Please see Figure 1-4 The present invention provides the following technical solution: a car horn cover that is easy to replace, including an outer frame 1, a set of through holes 2 are provided on the outer wall of the outer frame 1, and an inclined groove 3 is provided on the surface of both sides of the outer frame 1, and a pull handle 4 is respectively snapped into the inside of each groove 3.

[0025] The outer frame 1 and the through hole 2 constitute the car speaker cover, specifically the speaker cover installed on the A-pillar of the Sagitar car. The car speaker cover has a ring of adhesive layer on the outer edge of its mating side. During installation, the adhesive on one side of the car speaker cover is pressed firmly against the outer edge of the speaker box on the A-pillar of the Sagitar car, which makes it very convenient to complete the mating of the car speaker cover.

[0026] Each handle 4 has a connecting block 5 integrally connected to one end. A protrusion 6 is movably installed on both sides of the connecting block 5. The protrusion 6 is movably engaged in the connecting hole on the inner wall of the groove 3. A connecting post 7 is fixedly installed on one end of each of the two protrusions 6. A cam 8 is movably arranged between the two connecting posts 7. One side of the cam 8 is fixedly connected to one end of the rotating rod 9. The rotating rod 9 is movably connected to the rotating rod 9 through one side of the outer wall of the connecting block 5.

[0027] Preferably, a through groove 51 is provided at the center end of the mating block 5, and the inner diameter of the through groove 51 is adapted to the maximum diameter of the protrusion 6.

[0028] In practical use, when the cam 8 releases the vertical contact with the end 72, it pulls the mating block 5, causing the protrusion 6 to move. The arc-shaped structure of the outer wall of the protrusion 6 will move into the through groove 51 by being squeezed between it and the groove 3, so that the mating block 5 can be disassembled from the inside of the groove 3;

[0029] Preferably, the end of the connecting post 7 away from the protrusion 6 is fixedly connected to the outer wall of the center end of the limiting disk 71, and the other side of the outer wall of the center end of the limiting disk 71 is fixedly connected to the end 72;

[0030] The end 72 has a semi-circular structure. One end of the two ends 72 is in contact with the outer wall of the cam 8, and the outer wall of the limiting disk 71 is in contact with the inner wall of the through groove 51.

[0031] Two springs 73 are symmetrically installed between the two limiting plates 71.

[0032] In practical use, when the rotating rod 9 drives the cam 8 to rotate, the cam 8 will rotate against the arc-shaped outer wall of the end 72. When the cam 8 rotates, the spring 73 will retract and reset, and when the spring 73 resets, it will drive the limiting plate 71 to move towards the center end of the through groove 51. When the limiting plate 71 moves, it will drive the protrusion 6 into the through groove 51 through the connecting post 7, thereby causing the mating block 5 to disengage from the groove 3.

[0033] Preferably, a positioning disk 91 is fixedly sleeved at the center end of the rotating rod 9. The positioning disk 91 is movably installed inside the docking block 5, and the rotating rod 9 forms a positioning and movable docking with the docking block 5 through the positioning disk 91.

[0034] In actual use, when the rotating rod 9 rotates, it will drive the positioning disk 91 to rotate synchronously. The positioning disk 91 will be subject to the agreement of the docking block 5 and can only rotate in place, thus making the rotating rod 9 only able to rotate in place.

[0035] In use, the two ends 72 are pressed against both sides of the cam 8 by the tension of the two springs 73, so that the cam 8 can be kept in the adjusted position.

[0036] Preferably, the cam 8 is located at the center end of the through groove 51, and the maximum diameter of the cam 8 is smaller than the inner diameter of the through groove 51.

[0037] In practical use, the cam 8 can rotate smoothly inside the through groove 51, thereby allowing the protrusion 6 to extend and retract.

[0038] Working principle: When the outer frame 1 needs to be removed from the horn opening of the car, one end of the connecting block 5 is rotated and pressed into the groove 3. This causes the other end of the connecting block 5 to pry up from the inside of the groove 3, allowing the disassembly personnel to hold both connecting blocks 5 and pull them outwards.

[0039] In addition, when pulling the connecting block 5, the cam 8 needs to be adjusted to a vertical position between the two ends 72 by rotating the rod 9, so that the protrusion 6 can be firmly set in the groove 3. When the two connecting blocks 5 are pulled, the outer frame 1 can be pulled through the groove 3. During disassembly, this structure can effectively apply a pulling force to the outer frame 1, thereby improving the convenience of disassembling the outer frame 1.

[0040] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
