Description

Technical Field

[0001] This utility model relates to the field of automobile horn technology, specifically to an automobile snail horn. Background Technology

[0002] A snail horn is a car horn named for its snail-like shape, distinguishing it from a basin horn. The snail horn works by: current flows through a coil to the contacts, generating a magnetic force that pulls down the armature, forcing the diaphragm to move. This movement opens the contacts, interrupting the current and removing the magnetic force. The diaphragm, under its own elasticity and the action of a spring, returns to its original position along with the armature, closing the contacts and completing the circuit. Current then flows through the contacts again to the coil, generating a magnetic force, and the process repeats. This cycle continues, causing the diaphragm to vibrate continuously, thus producing sound.

[0003] Most car snail horns on the market are installed in the engine bumper area of ​​a car by screwing multiple screws onto a mounting bracket. The installation and removal process is relatively troublesome and time-consuming. In addition, most car snail horns have their openings facing downwards to facilitate sound transmission, but dust splashed up during vehicle operation can easily enter the horn, causing blockage and malfunction. Therefore, we have proposed a new type of car snail horn. Utility Model Content

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.

[0034] Please see Figures 1 to 7 A car snail horn includes a car front panel 2, a horn body 1 is mounted on the outside of the car front panel 2, a horn amplification port 4 for amplifying the sound is mounted on the outside of the horn body 1, a connecting rod 3 is provided between the horn body 1 and the car front panel 2, and the horn body 1 can be fixed to the connecting rod 3 by a quick installation device 101, thereby installing the horn body 1 on the car front panel 2, and the horn amplification port 4 can improve the horn sound;

[0035] The horn body 1 is provided with a quick-installation device 101 on the outside of the car front panel 2, which allows the horn body 1 to be quickly installed on the car front panel 2. The horn body 1 can be quickly installed on the car front panel 2 through the quick-installation device 101, which is convenient and quick to operate.

[0036] The horn body 1 is equipped with a first cylindrical mounting box 5 at its end. A second cylindrical mounting box 6 is installed outside the first cylindrical mounting box 5. A third cylindrical mounting box 7 is provided inside the second cylindrical mounting box 6. The quick installation device 101 includes a sliding pressing component and a positioning and fixing component. The positioning and fixing component is installed at the bottom of the third cylindrical mounting box 7. The sliding pressing component is installed at the top of the third cylindrical mounting box 7. The connecting rod 3 is located at the center of the positioning and fixing component and the sliding pressing component. The sliding pressing component can move up and down outside the third cylindrical mounting box 7 and contact the positioning and fixing component to generate pressure and fix the connecting rod 3. The connecting rod 3 installed on the front panel 2 of the car is aligned with the center of the third cylindrical mounting box 7 and inserted into the center of the positioning and fixing component inside the third cylindrical mounting box 7. Then, by rotating the sliding pressing component downward, the positioning and fixing component is pressed to deform and fix the connecting rod 3. In this way, the horn body 1 can be quickly installed on the front panel 2 of the car.

[0037] The speaker's amplification port 4 is also equipped with a dustproof device 102 to prevent dust from entering the speaker body 1. The dustproof device 102 can effectively prevent dust splashed by the vehicle during driving from entering the speaker body 1, thus extending the service life of the speaker body 1.

[0038] Please see Figures 1 to 4 A third cylindrical mounting box 7 is fitted onto the center of the second cylindrical mounting box 6. The second cylindrical mounting box 6 and the third cylindrical mounting box 7 fit together. The third cylindrical mounting box 7 has a first slot 8 inside and a circular through hole at the top. The connecting rod 3 can enter the first slot 8 through the circular through hole at the top of the third cylindrical mounting box 7. Then, by rotating and sliding the pressing component downward, the positioning and fixing component inside the first slot 8 is pressed to quickly fix the connecting rod 3.

[0039] Please see Figures 1 to 4 The positioning and fixing assembly includes a fixing plate 9, a limiting groove 10, a deformation fixing device 11, and a convex block 12;

[0040] A fixing plate 9 is installed at the bottom of the first empty slot 8. A limiting groove 10 is opened at the center bottom position of the fixing plate 9. A deformable deformation retainer 11 is installed at the top of the fixing plate 9. A protruding block 12 is installed at the top of the deformation retainer 11. The connecting rod 3 can extend into the interior of the deformation retainer 11 and contact the bottom of the limiting groove 10. When the connecting rod 3 enters the first empty slot 8 through the circular through hole at the top of the third cylindrical mounting box 7 and contacts the limiting groove 10 on the fixing plate 9, the sliding extrusion assembly is rotated and moved downward. The sliding extrusion assembly extrudes the protruding block 12, so that the deformation retainer 11 is subjected to force and begins to shrink and fit the connecting rod 3 tightly, thereby quickly fixing the connecting rod 3.

[0041] Please see Figures 1 to 4 The sliding extrusion assembly includes a cylindrical limiter 13, a concave groove 14, a first thread 17, a second thread 18, and a ring rotator 25.

[0042] The circular through hole has a second thread 18 on its outside, and the cylindrical limiter 13 has a first thread 17 on its outside. The cylindrical limiter 13 is installed on the top of the third cylindrical mounting box 7 through the threaded connection between the first thread 17 and the second thread 18. The bottom of the cylindrical limiter 13 has a concave groove 14, and the top of the cylindrical limiter 13 is equipped with a ring rotator 25 for rotating the cylindrical limiter 13. When the connecting rod 3 enters the first empty groove 8 through the circular through hole at the top of the third cylindrical mounting box 7 and comes into contact with the limiting groove 10, the ring rotator 25 is rotated to drive the cylindrical limiter 13 to rotate. The first thread 17 on the cylindrical limiter 13 and the second thread 18 on the outside of the circular through hole are threaded together. The cylindrical limiter 13 moves down, and the concave groove 14 is squeezed against the convex block 12. As a result, the deformation fixer 11 is subjected to force and begins to shrink and tighten the connecting rod 3, thereby quickly fixing the connecting rod 3.

[0043] Please see Figures 1 to 4 The convex block 12 is a cylindrical trapezoidal shape that is narrower at the top and wider at the bottom, and the concave groove 14 is also a cylindrical trapezoidal shape that is narrower at the top and wider at the bottom. The bottom of the concave groove 14 is adapted to the top of the convex block 12. The adaptation of the bottom of the concave groove 14 to the top of the convex block 12 allows the cylindrical limiter 13 to press the deformation fixer 11 when it moves down, thereby driving the deformation fixer 11 to retract and fix the connecting rod 3.

[0044] Please see Figures 1 to 6 The dustproof device 102 includes a dustproof net 19, a vibrator 20, and a vibrating ball 21;

[0045] A vibrator 20 is installed on the outside of the speaker's amplification port 4. A dustproof mesh 19 is installed at the center of the vibrator 20 to prevent dust from entering the speaker body 1. The vibrator 20 has an annular groove inside, within which multiple vibrating beads 21 are slidably connected. The dustproof mesh 19 intercepts splashing dust, preventing it from entering the speaker body 1 and affecting its use. Vibration occurs when the car is moving or the horn is honked, causing the vibrating beads 21 to roll within the annular groove. This rolling and collision causes the dustproof mesh 19 to vibrate, thus cleaning the dust from the mesh.

[0046] The vibrating bead 21 is also equipped with a vibration device to increase the vibration of the vibrating bead 21. The vibration device can increase the vibration of the vibrating bead 21 by vibration, so as to better vibrate the dustproof net 19 and thus better clean the dust on the dustproof net 19.

[0047] Please see Figures 1 to 7 , the tremor device includes a first tuning fork 15, a second tuning fork 22, and a third tuning fork 23,

[0048] The vibrating ball 21 has a circular groove 24 inside, and a second tuning fork 22 is installed in the circular groove 24. A first tuning fork 15 and a third tuning fork 23 are installed symmetrically to the second tuning fork 22 in the circular groove 24. The first tuning fork 15 and the second tuning fork 22 intersect each other, and the second tuning fork 22 and the third tuning fork 23 intersect each other. The vibration generated when the vibrating ball 21 rolls causes the first tuning fork 15, the second tuning fork 22 and the third tuning fork 23 to vibrate with each other, and the mutual vibration will also vibrate the vibrating ball 21, so that the vibrating ball 21 vibrates for a longer time, and the vibration cleaning effect of the dustproof net 19 is better.

[0049] Please see Figures 1 to 4 The opening size of the limiting groove 10, the inner wall size of the deformation retainer 11, and the size of the second empty groove 16 are all larger than the outer wall of the connecting rod 3. The deformation retainer 11 is made of deformable polyvinyl chloride. The inner wall size of the deformation retainer 11 and the size of the second empty groove 16 are larger than the outer wall of the connecting rod 3, which facilitates the deformation of the deformation retainer 11 to fix the connecting rod 3. The deformation retainer 11 is made of deformable polyvinyl chloride and can deform under the pressure of the cylindrical limiter 13, thereby fixing the connecting rod 3.

[0050] In summary, this type of car snail horn, when in use, firstly, a connecting rod 3 is installed on the front panel 2 of the car. The horn body 1 is picked up, and the connecting rod 3 is inserted and contacts the limiting groove 10. Then, by rotating the ring rotator 25, the ring rotator 25 drives the cylindrical limiter 13 to rotate. The cylindrical limiter 13 gradually moves into the first empty groove 8 through the threaded connection between the first thread 17 and the second thread 18 until it abuts against the deformation retainer 11. The concave groove 14 and the convex block 12 are matched. Through the continuous downward movement of the cylindrical limiter 13, the deformation retainer 11 is squeezed, and the deformation retainer 11 deforms and continuously contracts to fit tightly against the connecting rod 3 until the connecting rod 3 is completely pressed. At this time, the rotation of the ring rotator 25 is stopped, and the quick installation of the horn body 1 is completed. When disassembly is required... Simply rotate the ring rotator 25 in the opposite direction. The ring rotator 25 drives the cylindrical limiter 13 to disengage from the deformation retainer 11. The deformation retainer 11 releases its fixation on the connecting rod 3. Then, the horn body 1 can be pulled out. At this moment, quick disassembly is completed. When the vehicle is moving, the dust splashed up will be blocked on the dustproof net 19 and will not enter the interior to affect the use of the horn. When the horn is pressed or the vehicle is moving, vibration will be generated. The vibrating ball 21 will be vibrated and roll and collide with each other inside the vibrator 20. The first tuning fork 15, the second tuning fork 22 and the third tuning fork 23 inside the vibrating ball 21 will collide with each other due to vibration, and amplify the vibration of the vibrating ball 21. The rolling and collision of the vibrating ball 21 will vibrate the dustproof net 19, thereby vibrating and cleaning the dust on the dustproof net 19.
