Description

Technical Field

[0001] This utility model relates to the field of automobile horn technology, and more specifically, to an automobile horn that is easy to assemble. Background Technology

[0002] A car horn is a warning and alert device installed on a car to emit sound signals to pedestrians, other vehicles, or road users to improve driving safety. It is usually an electromagnetic horn (electric horn), which produces sound by driving the diaphragm to vibrate through an electromagnetic coil. It is snail-shaped in appearance, and has a loud, penetrating sound with a thick tone. It is an important safety warning device, and proper use of the horn can improve driving safety.

[0003] Chinese Patent Announcement No. CN219068349U discloses a solution for an adjustable car horn. The output shaft of the motor rotates, which drives the winding wheel to rotate, which in turn drives the nylon rope to pull the metal adjusting rod along the surface of the rheostat. This allows for adjustment of the circuit resistance and current, thus changing the horn's volume. The rubber slider ensures the stability of the metal adjusting rod's movement. Moving the lever causes the screw to rotate along the inside of the threaded sleeve, which adjusts the gap between the connecting plate and the mounting plate, facilitating the installation of the horn in mounting locations of different sizes and ensuring installation stability.

[0004] Traditional car horns are installed using bolts and nuts. However, car horns are usually installed inside the front frame of the vehicle. This area has complicated wiring and limited space, and bolt installation takes a long time because each bolt and nut needs to be tightened individually. This makes installation inconvenient, and bolt installation is also prone to bolt loosening, requiring regular inspection and maintenance.

[0005] Therefore, a car horn that is easy to assemble is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problem to be solved: This utility model provides a car horn that is easy to assemble, which can improve the problems existing in related technologies: Car horns require a long time to install by bolts because the bolts and nuts need to be tightened one by one, which causes inconvenience in installation. At the same time, bolt installation is prone to bolt loosening, which requires regular inspection and maintenance, otherwise the mounting parts may become loose or fall off.

[0007] 2. Technical Solution: To solve the above problems, the present invention adopts the following technical solution.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 A car horn that is easy to assemble includes a horn body 1, a sound shell 2 fixedly installed on the outer end of the horn body 1, an interface 4 installed on the outer end of the horn body 1, a mounting base 5 fixedly connected to the outer end of the horn body 1, an outer cover assembly 3 for blocking impurities installed on the outer end of the sound shell 2, a mounting assembly 6 provided on the outer end of the mounting base 5, and a snap-fit ​​assembly 7 provided inside the mounting assembly 6. The mounting assembly 6 includes a pin 65 and a movable sleeve 64. The movable sleeve 64 is movably fitted on the outer end of the pin 65. The outer end of the pin 65 has multiple annularly distributed mounting grooves 69. Each of the multiple mounting grooves 69 is rotatably connected to a limiting piece 67. After the pin 65 is inserted into the bolt hole, it is clamped on both sides of the bolt hole by the movable sleeve 64 and the multiple unfolded limiting pieces 67 to form a quick fixation.

[0032] Compared to traditional car horns that use bolts for mounting, the car horn in this design is easier to install. The horn body 1 mainly consists of an electromagnetic coil and a diaphragm that vibrate under electromagnetic force to generate sound waves. A sound-producing shell 2, fixed to the outer end of the horn body 1, communicates with the interior of the horn body 1, allowing the sound emitted by the horn body 1 to be emitted through the sound-producing shell 2. An interface 4 is fixed to the outer end of the horn body 1; interface 4 is mainly used for signal connection to the vehicle and for connecting to power. An outer cover assembly 3 is installed on the outer end of the sound-producing shell 2; the outer cover assembly 3 is mainly used to protect the opening of the sound-producing shell 2, preventing external debris from entering and causing blockage. A mounting base 5 is fixed to the outer end of the horn body 1. The mounting base 5 is mainly used to install the mounting component 6. After inserting the pin 65 into the pre-drilled bolt hole on the frame, the limiting piece 67 is pushed outward by the spring piece 73 to unfold it. Then, the movable sleeve 64 is pushed outward by the telescopic spring 63, so that the limiting piece 67 and the movable sleeve 64 can be clamped on both sides of the bolt hole to form a quick fixation. At the same time, the spring piece 73 will also extend to the outside through the through hole 610 and then be clamped on the inside of the bolt hole by the slot 74, thus forming a secondary fixation. The installation is faster than bolt installation by cooperating with the mounting component 6 and the clamping component 7, eliminating the bolt tightening step, thereby saving installation time and improving the convenience of installation.

[0033] Please see Figure 3 and Figure 4The mounting assembly 6 also includes a telescopic spring 63, a fixing ring 62 fixedly connected to the bottom end of the pin 65, a fixing block 61 fixedly connected to the bottom end of the fixing ring 62, the pin 65 is fixedly installed on the outer end of the mounting base 5 through the fixing block 61, and the telescopic spring 63 is sleeved on the outer end of the pin 65.

[0034] The telescopic spring 63 is located between the movable sleeve 64 and the fixed ring 62. The two ends of the telescopic spring 63 abut against the fixed ring 62 and the movable sleeve 64 respectively. The movable sleeve 64 moves forward by the force of the telescopic spring 63.

[0035] The outer end of the movable sleeve 64 has an annular groove 68, and a gasket 66 is installed inside the groove 68. The inside of the pin 65 is hollow.

[0036] In this design, a fixing ring 62 is fixed to the bottom of the pin 65, and a fixing block 61 is fixed to the bottom of the fixing ring 62. The fixing block 61 is fixed to the mounting base 5. The pin 65 is fixed to the mounting base 5 by the connection between the fixing ring 62 and the fixing block 61. The interior of the pin 65 is hollow. A telescopic spring 63 is sleeved on the outer end of the pin 65. At the same time, a movable sleeve 64 is movably sleeved around the pin 65. The movable sleeve 64 is slidably connected to the outer end of the pin 65. The telescopic spring 63 is located between the movable sleeve 64 and the fixing ring 62, and its two ends abut against the fixing ring 62 and the movable sleeve 64 respectively. Since the fixing ring 62 is fixed, the force of the telescopic spring 63 will push the movable sleeve 64 outward.

[0037] Multiple mounting slots 69 are formed at the outer end of the pin 65. A limiting piece 67 is rotatably connected inside each mounting slot 69. The limiting piece 67 mainly engages by rotating and unfolding. During installation, the pin 65 can be directly inserted into the pre-drilled bolt holes on the frame. At this time, the multiple limiting pieces 67 are pressed inward by the bolt holes, engaging the component 7. Simultaneously, they rotate into the mounting slots 69, fitting snugly without protruding from the surface of the pin 65. At the same time, the movable sleeve 64 is also compressed, sliding on the pin 65 and compressing the telescopic spring. When the limiting piece 67 is fully passed through the bolt hole, it is pushed by the snap-fit ​​assembly 7 and rotates outward at a certain angle to disengage from the mounting groove 69. When released, the force of the telescopic spring 63 pushes the movable sleeve 64, causing the movable sleeve 64 to press against the surface of the bolt hole and pull the pin 65 back. This causes the limiting piece 67 to be fully unfolded after being compressed. At this time, the limiting piece 67 and the movable sleeve 64 will be clamped on both sides of the bolt hole, thus completing the fixation. This eliminates the need for bolt fixation, reducing time and labor costs and reducing failures caused by loose bolts.

[0038] It is worth mentioning that a groove 68 is provided on the movable sleeve 64, and a gasket 66 is installed inside the groove 68. The gasket 66 is made of rubber. When the movable sleeve 64 is pressed against the surface of the bolt hole, the gasket 66 will also press against its surface, thus playing a buffering and shock-absorbing role in the middle. It can play a buffering and protective role for the horn body 1 when the vehicle vibrates.

[0039] Please see Figure 4 and Figure 5 The snap-fit ​​assembly 7 includes two connecting rings 71 and a plurality of ring-shaped spring pieces 73. Each end of the spring piece 73 is fixedly connected to a fixing wing 72, and the spring piece 73 is fixed between the two connecting rings 71 by the two fixing wings 72.

[0040] The outer end of the spring piece 73 has a slot 74, and multiple mounting slots 69 have through holes 610 inside. The through holes 610 are connected to the inside of the pin 65. The connecting ring 71 is fixedly installed on the inner wall of the pin 65, and the spring piece 73 extends to the outside through the through hole 610.

[0041] In this design, the snap-fit ​​component 7 is fixed inside the pin 65. Both connecting rings 71 are fixed to the inner wall of the pin 65. Fixing wings 72 are fixed to both ends of the spring pieces 73, and the two fixing wings 72 are respectively fixed to the two connecting rings 71. Multiple spring pieces 73 are arranged in a ring on the connecting rings 71, and are configured one-to-one with the limiting pieces 67. Simultaneously, a through hole 610 is opened inside each mounting groove 69, opening up the interior of the pin 65. The spring pieces 73 are arc-shaped, allowing each spring piece 73 to extend through the through hole 610. To the outside, it abuts against the limiting piece 67, pushing the limiting piece 67 outward. When the limiting piece 67 is compressed, the spring piece 73 can be compressed by its own elasticity. After the limiting piece 67 passes through the bolt hole, the spring piece 73 springs back to its original position, which can push the limiting piece 67 outward and make it disengage from the mounting groove 69. This can help the limiting piece 67 unfold. At the same time, a slot 74 is opened on the outside of the spring piece 73, so that the outer surface of the spring piece 73 can form two crests, which are mainly used to be stuck in the bolt hole, thereby playing a secondary auxiliary fixing role and making the installation more stable.

[0042] Please see Figure 2 The outer casing assembly 3 includes a movable retaining ring 31 and a fixed retaining ring 33. The fixed retaining ring 33 is fixedly installed on the inner wall of the sound-producing housing 2. The movable retaining ring 31 matches the fixed retaining ring 33. The movable retaining ring 31 is installed at the opening of the sound-producing housing 2 through the fixed retaining ring 33. A filter screen 34 is installed on the inner side of the movable retaining ring 31, and a sponge 32 is installed on the inner side of the filter screen 34.

[0043] The outer casing assembly 3 in this design is mainly used to form a barrier at the opening of the speaker housing 2. A retaining ring 33 is fixed on the inner wall of the speaker housing 2. A movable retaining ring 31 matches the retaining ring 33, and the movable retaining ring 31 and the retaining ring 33 can be connected together by a buckle. A filter screen 34 is installed inside the movable retaining ring 31. The filter screen 34 is mainly used to block dust and debris from the external environment. A sponge 32 is installed on the back of the filter screen 34. The sponge 32 is mainly used to block external water and play a waterproof role. Since there are gaps in the filter screen 34, it cannot block rainwater when it rains. By attaching the sponge 32 to the inside, a barrier can be formed. Through the cooperation of the filter screen 34 and the sponge 32, the inside of the speaker housing 2 can be kept clean, thereby improving the service life of the speaker body 1.

[0044] Working principle: When installing this device, simply insert the pin 65 into the pre-drilled bolt hole on the frame. First, multiple limiting pieces 67 are squeezed by the bolt hole and rotate into the mounting groove 69, matching the mounting groove 69. At the same time, the movable sleeve 64 is also squeezed and slides on the pin 65. When the limiting piece 67 has completely passed through the bolt hole, the limiting piece 67 is pushed away from the mounting groove 69 by the spring piece 73. When released, the force of the telescopic spring 63 causes the movable sleeve 64 to press against the surface of the bolt hole, pulling the pin 65 back. This causes the limiting piece 67 to be fully unfolded after being squeezed. At this time, the limiting piece 67 and the movable sleeve 64 will be clamped on both sides of the bolt hole, thus completing the fixation. At the same time, the slot 74 on the outside of the spring piece 73 can form two crests, which can be clamped in the bolt hole to form a secondary fixation, eliminating the need for bolt fixation and improving the convenience of installation.
