Technical Field

[0001] This utility model relates to the field of electronically controlled dual-tone air horn technology, specifically to an electronically controlled dual-tone air horn with a protective structure. Background Technology

[0002] An electronically controlled dual-tone air horn is a common car audio device, typically used for vehicle warning and alert functions. It combines the features of an electronic audio system and an air horn, capable of emitting two different frequencies and tones to alert other drivers or pedestrians to the vehicle's presence or movement.

[0003] Utility model patent CN213183568U discloses a square-hole dual-tone electrically controlled air horn, including a connecting base. One end of the connecting base is connected to a bass horn and a treble horn, respectively. A solenoid valve is fixedly connected to the top of the connecting base. Multiple locking blocks are fixedly connected to the outer surfaces of the bass and treble horns. Rubber damping strips are engaged with the outer surfaces of the locking blocks. The inner surface of the rubber damping strips has a groove that matches the locking blocks. There are two rubber damping strips, distributed on the outer surfaces of the bass and treble horns. This patent allows two rubber damping strips to be installed on the outer surfaces of the bass and treble horns respectively through the cooperation of the locking blocks and grooves, providing a certain degree of protection for the bass and treble horns and preventing wear on their outer surfaces.

[0004] However, existing electronically controlled dual-tone air horns still have some shortcomings: most existing electronically controlled dual-tone air horns use open-ended tweeter and woofer units for horn warning. Due to the complexity of road conditions, dust, sewage and other impurities can easily damage the tweeter and woofer units. Utility Model Content

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Both the tweeter body 2 and the woofer body 3 are provided with a protective structure 11. The protective structure 11 includes a dirt cover 111. The dirt cover 111 is in contact with the right side of both the tweeter body 2 and the woofer body 3. A movable plate 112 is fixedly connected to the upper left end of the dirt cover 111. A fixed shell 113 is fixedly connected to the upper side of both the tweeter body 2 and the woofer body 3. The fixed shell 113 is slidably connected to the movable plate 112. A support member 11 is fixedly connected to the inner left side wall of the fixed shell 113. 4. A micro motor 115 is fixedly installed on the upper end of the support 114. The output shaft of the micro motor 115 is fixedly connected to a screw 116. The screw 116 is threadedly connected to the movable plate 112 and rotatably connected to the fixed shell 113. Through the threaded connection, when the screw 116 rotates, it can drive the movable plate 112 to move. Through the arrangement of the micro motor 115, screw 116 and other structures, the movable plate 112 can be driven to move, thereby driving the anti-fouling cover 111 to move.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixing block 117 is fixedly connected to the lower side of both the tweeter body 2 and the woofer body 3. A guide plate 118 is slidably connected to the inner wall of the fixing block 117. The guide plate 118 contacts the anti-fouling cover 111. A positioning hole 119 is opened at the lower end of the guide plate 118. A positioning block 120 is slidably connected to the inner wall of the fixing block 117. The positioning block 120 is slidably connected to the positioning hole 119. A guide rod 121 is fixedly connected to the lower end of the positioning block 120. The guide rod 121 is slidably connected to the fixing block 117. A spring 122 is provided on the outer side of the guide rod 121. Through the setting of the positioning hole 119, positioning block 120 and other structures, the guide plate 118 can be positioned, thereby positioning the anti-fouling cover 111.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Multiple positioning holes 119 are provided, and the multiple positioning holes 119 are evenly distributed on the guide plate 118. The positioning holes 119 are provided to facilitate positioning with the positioning block 120. One end of the spring 122 is welded to the fixing block 117, and the other end of the spring 122 is welded to the positioning block 120. The positioning block 120 can be tightened by the spring 122.

[0024] The specific implementation process of this utility model is as follows: When in use, the anti-fouling cover 111 can protect the electronically controlled dual-tone air horn in the idle state, avoiding the intrusion of dust particles, mud and other impurities. The micro motor 115 is started to drive the output shaft to rotate, thereby driving the screw 116 to rotate. Under the threaded connection, the moving plate 112 can be driven to move, thereby driving the anti-fouling cover 111 to move, so that the anti-fouling cover 111 is away from the electronically controlled dual-tone air horn, so as to ensure the normal operation of the electronically controlled dual-tone air horn.

[0025] When the anti-fouling cover 111 moves, it can drive the guide plate 118 to move, so that the guide plate 118 moves stably along the inner wall of the fixed block 117, and the inner wall of the positioning hole 119 presses the positioning block 120 to push the guide rod 121 to move. The spring 122 deforms, and finally the positioning block 120 is disengaged from the positioning hole 119. Under the action of force, the positioning block 120 moves along the surface of the guide plate 118. When the positioning block 120 slides into the next positioning hole 119, the spring 122 returns to its original deformation to push the positioning block 120 into the positioning hole 119, limit the guide plate 118, and thus position the anti-fouling cover 111 for use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
