DESC:FIELD OF THE INVENTION

[0001] The present disclosure relates to an automotive horn, and more particularly, the present disclosure relates to a disc-based electro-mechanical horn having a dual circuit breaker.

BACKGROUND

[0002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

[0003] An electro-mechanical horn is an electric device used in a vehicle to provide a general aural signal for traffic ahead or around the vehicle. The electro-mechanical horn typically uses an electromagnetic core and a moving core, the moving core is attracted towards the electromagnetic core on the actuation of the electromagnetic core. The actuation of the electromagnetic core is done via the contacts. However, the electro-mechanical horns are susceptible to failure due to the failure of the contacts. The failure resulting from the failure of the contacts typically arises due to a sharp temperature rise. The sudden rise in the temperature results in arcing at localized points thereby creating the failure of the contacts. In addition, during normal operations of the electro-mechanical horn, there are regular surges of the current in the system creating heat spots that may lead to the failure of the electro-mechanical horn.

[0004] Some existing solutions for the existing problem have been explained in Indian Patent no. 2932/MUM/2012. The above-mentioned patents explain a dual-contact horn. However, 2932/MUM/2012 does not explain any reduction of heat in the dual-contact horn. However, heat generation is a very important factor in the durability of the dual-contact horn. In addition, for controlling the surge in current one or more capacitors are used in the dual-contact horn.

[0005] Therefore, there is a need for an electro-mechanical horn that may sustain long life, have fewer heating localized spots, and is adapted to control/absorb the extra current in the system.

[0006] The drawbacks/difficulties/disadvantages/limitations of the conventional techniques explained in the background section are just for exemplary purposes and the disclosure would never limit its scope only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks/disadvantages of the conventional arts which are not explicitly captured above.

SUMMARY

[0007] This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.

[0008] The present disclosure relates to a horn assembly. The horn assembly includes a housing, a horn unit disposed in the housing and adapted to generate a sound, and a bobbin assembly disposed in the housing and adapted to actuate the horn unit. In addition, the horn assembly includes a first contact breaker assembly adapted to selectively couple to the bobbin assembly to supply electric current thereto, and a second contact breaker assembly adapted to selectively couple to the bobbin assembly to supply electric current thereto. The one of the first contact breaker assembly and the second contact breaker assembly is adapted to selectively couple to the bobbin assembly based on a user input.

[0009] The horn assembly is actuated by one of two contact breaker assemblies namely the first contact breaker assembly, and the second contact breaker assembly acting as redundant mechanisms for actuating the horns in case one assembly malfunctions or is inoperable.

[0010] The arcing due to less current and surge suppression by a diode is reduced, improving the overall life. Due to this, the long-term cost of operation of the horn assembly is also reduced. In addition, the operating temperature of the horn assembly is also reduced making the design sturdy, consuming less potential energy, and avoiding any draining of the battery power. In a test conducted on the horn assembly, the horn assembly is operating at almost double the life of a conventional housing available in the market.

[0038] In an embodiment, the first contact breaker assembly 132 may adapted to be actuated upon a failure of the second contact breaker assembly 134. The actuation of the one of the contact breaker assemblies 132, 134 facilitates in increasing the life of the horn assembly 100. In addition, the horn assembly 100 includes an electrical coupler 200 (shown in Figure 4) to facilitate an electrical coupling of the bobbin assembly 115 with a first plate 140 of the first contact breaker assembly 132 and a first plate 154 of the second contact breaker assembly 134. The electric coupler 200 facilitates in enabling a parallel arrangement of the electrical circuitry of the first contact breaker assembly 132 and the second contact breaker assembly 134.

[0039] Referring to Figure 5, a top view of the bobbin assembly 115 is shown. The bobbin assembly 115 may include a central portion 122 defining a base 124, the first pair of bars 126 extending outwardly from the base 124, and the second pair of bars 128 extending outwardly from the base 124. The first pair of bars 126 and the second pair of bars 128 includes a plurality of holes 130 to facilitate the mounting of the one or more components of the horn assembly 100.

[0040] In an embodiment, the first pair of bars 126 may be adapted to extend outwardly from the base 124 of the central portion 122, and the second pair of bars 128 may be disposed opposite to the first pair of bars 126 and extend outwardly from the base 124 of the central portion 122. In an alternate embodiment, the first pair of bars 126 and the second pair of bars 128 include a plurality of holes 130 to facilitate the electrical coupling of the first contact breaker assembly 132 and the second contact breaker assembly 134 to actuate the horn unit 101.

[0041] Referring to Figure 6, the first contact breaker assembly 132 is shown. The first contact breaker assembly 132 includes a pair of contacts 136, and 138 adapted to move in an attached and a separate configuration. In an attached configuration the pair of contacts 136, and 138 abut one other and facilitate the passing of the current. In a separate configuration, the pair of contacts 136, and 138 are separated from one other and an air gap exists between the pair of contacts 136, and 138 thereby restricting any flow of current from the first contact breaker assembly 132.

[0042] In addition, first contact breaker assembly 132 includes the first plate 140 having the first contact 136 and adapted to move in response to the user input, a second plate 142 disposed spaced apart from the first plate 140 and includes the second contact 138 adapted to engage and disengage with the first contact 136 of the first plate 140. In an alternate embodiment, the pair of contacts 136, and 138 is disposed on the first plate 140 and the second plate 142 pivotally coupled with the first plate 140.

In another embodiment, the first plate 140 and the second plate 142 may define a rectangular shape configuration defining a bend at an angle in between a total length. The first plate 140 and the second plate 142 may define any other shape configuration without departing from the scope of the present disclosure.

[0044] The two plates 140, and 142 are adapted to converge and separate resulting in the attachment and separation of the pair of contacts 136, and 138. Additionally, the first contact breaker assembly 132 includes an insulation tab 144 sandwiched between the first plate 140 and the second plate 142 to enable the restoration of the pair of contacts 136, and 138 and insulate the two plates (140, 142).

In an example, the second plate 142 may be made of but is not limited to Sandvik steel 12R11.

[0046] Referring to Figure 7, the second contact breaker assembly 134 is shown. The second contact breaker assembly 134 includes a pair of contacts 150, and 152 adapted to move in an attached and a separate configuration. In an attached configuration the pair of contacts 150, and 152 abut one other and facilitate the passing of the current. In a separate configuration, the pair of contacts 150, and 152 are separated from one other and an air gap exists between the pair of contacts 150, and 152 thereby restricting any flow of current from the second contact breaker assembly 134. In an example, the pair of contacts 150, 152 may be made of materials such as but not limited to tungsten.

[0047] The second contact breaker assembly 134 includes the first plate 154 having the first contact 150 and adapted to move in response to the user input, and a second plate 156 disposed spaced apart from the first plate 154 and includes the second contact 152 adapted to engage and disengage with the first contact 150 of the first plate 154. In an embodiment, the pair of contacts 150, and 152 are disposed on the first plate 154 and the second plate 156 pivotally coupled with the first plate 154. In an example, the second plate 156 may be made of but not limited to Sandvik steel 12R11. In an example, the first plate 154 may be made of but not limited to Sandvik steel 12R11.

[0048] The two plates 154, and 156 are adapted to converge and separate resulting in attachment and separation of the pair of contacts 150, and 152. Additionally, the second contact breaker assembly 134 includes an insulation tab 158 sandwiched between the first plate 154 and the second plate 156 to facilitate the restoration of the pair of contacts 150, and 152 and insulate the two plates 154, 156. Additionally, the second contact breaker assembly 134 includes a screw assembly 162 coupled with the first plate 154 to facilitate the engagement and the disengagement of the pair of contacts 150, 152 in response to the user input.

[0049] In an alternate embodiment, screw assembly 162 may be adapted to move the pair of contacts 150, and 152 together to couple with one other and adapted to move the pair of contacts 150 and 152 away from one other to deactivate the circuit. The actuation of the screw 162 may be done manually to facilitate the actuation and deactivation of the second contact breaker assembly 134. In an embodiment, the housing 102 may include a plurality of holes to facilitate the installation of the two screw assemblies 148, 162. In an alternate embodiment, the housing 102 having the plurality of holes may further facilitate the snap fitting of the thereby eliminating the two screw assembly 148, 162.

[0050] Referring to Figure 8, a circuit diagram 800 of the horn assembly 100 having the first contact breaker assembly 132 in an actuated state and the second contact breaker assembly 134 in a deactivated state is shown. The circuit diagram 800 of the horn assembly 100 having the first contact breaker assembly 132 and the second contact breaker assembly 134 positioned parallelly to facilitate the actuation of the bobbin assembly (not shown in Figure 8) is shown. As shown, the circuit 800 of the horn assembly 100 is coupled with a battery 170 and a coil 172 to facilitate the flowing of the electrical charge into the circuit. In addition, the circuit diagram 800 of the horn assembly 100 includes a switch 174 to facilitate the actuation of the horn assembly 100.

[0051] In one example, the first contact breaker assembly 132 is positioned in an activated arrangement to facilitate the actuation of the bobbin assembly (not shown) via the first contact breaker assembly 132. In addition, the first contact breaker assembly 132 includes a diode 176a positioned parallelly to facilitate the adsorption of the current in case of any surge and prevent any arching or overheating of the circuit 800. The first contact breaker assembly 132 may be actuated manually and the second contact breaker assembly 134 may be deactivated in a normal operating configuration. In an example, the first contact breaker assembly 132 may be in an activated state by the OEMs, and the second contact breaker assembly 134 may be in a deactivated state by the OEMs.

[0052] Referring to Figure 9, a circuit diagram 900 of the horn assembly 100 having the first contact breaker assembly 132 in a deactivated state and the second contact breaker assembly 134 in an activated state is shown. In the circuit diagram 900, the first contact breaker assembly 132 is disposed in a closed state and the second contact breaker assembly 134 is disposed in an open state configuration. This operating condition for the circuit diagram 900 may occur when the first contact breaker assembly 132 is worn out or has some problems. The first contact breaker assembly 132 may be deactivated by the screw (not shown in Figure 9) and the second contact breaker assembly 134 may be activated by the screw. The second contact breaker assembly 134 facilitates the transmission of the electrical charge to the bobbin assembly (not shown) and facilitates the actuation of the horn assembly 100. In addition, the second contact breaker assembly 134 includes a diode 176b positioned parallelly to facilitate the adsorption of the current in case of any surge and prevent any arching or overheating of the circuit 900.

[0053] As shown in Figure 1, the moving iron core 116 is adapted to be positioned above the bobbin assembly 115. The moving iron core 116 is adapted to move towards the bobbin assembly 115 in response to the actuation of the bobbin assembly 115. In addition, the moving iron core 116 may be adapted to strike in response to the actuation of the at least one of the first contact breaker assembly 132 and the second contact breaker assembly 134.

[0054] The actuation of the bobbin assembly 115 facilitates the generation of the magnetic field and the moving iron core 116 is adapted to be attracted toward the bobbin assembly 115. In addition, the horn assembly 100 includes the switch 174 to facilitate the actuation of the at least one of the first contact breaker assembly 132 and a second contact breaker assembly 134 to facilitate the closing of the circuit to facilitate the flow of current in the bobbin assembly 115.

[0055] Further, the horn assembly 100 includes the diaphragm 117 adapted to couple with the moving iron core 116 to facilitate the generation of sound upon striking the fixed nucleus 112 of the bobbin assembly 115, the movement of the moving iron core 116 facilitates the movement of the diaphragm 117 thereby vibrating the diaphragm 117 to facilitate the production of the sound. In an embodiment, the fixed nucleus 112 may include a fixed iron core and is configured to generate a magnetic field to influence the moving iron core 116 to strike the moving iron core 116 upon receipt of an electric current. The fixed iron core and the moving iron core 116 are coupled via one of the first contact breaker assembly 132 and the second contact breaker assembly 134.

[0056] Additionally, the horn assembly 100 includes the washer 118 adapted to couple with the diaphragm 117 to facilitate the restoration of the diaphragm 117 and the moving iron core 116 once the current is stopped from the circuit and the magnetic field fades away. The movement of the diaphragm 117 and the moving iron core 116 may be performed several times in a second.

[0057] As an example, the oscillation motion of the diaphragm 117 and the moving iron core 116 is at around 440 cycles per second for high pitch horn. For mid-pitch horns, the oscillation motion of the diaphragm 117 and the moving iron core 116 is at 410, and around 340 cycles per second for low-pitch horns. In this manner, the diaphragm 117 and the moving iron core 116 are set into periodic motion. The periodic motion of the diaphragm 117 and the moving iron core 116 facilitates the striking of the fixed nucleus 112 in every cycle.

[0058] The periodic movement of the moving iron core 116 and striking of the moving iron core 116 with the fixed nucleus 112 facilitates the production of vibration in the diaphragm 117. An air column above the diaphragm 117 gets this pressurized air and these vibrations get amplified through the resonator 119 and amplified sound is produced.

[0059] The advantages of the horn assembly 100 are now explained. The horn assembly 100 is actuated by one of two contact breaker assemblies 132, and 134 like the first contact breaker assembly 132, and the second contact breaker assembly 134 enabling an alternative solution for blowing horns in case one assembly malfunctions or has any other kind of problem. In addition, the heat produced at the localized points will be less as the current is distributed in two different paths.

[0060] The arcing due to less current and surge suppression by the diode 176a, 176b is reduced, improving the overall life. Due to this, the long-term cost of operation of the horn assembly 100 is also reduced. In addition, the operating temperature of the horn assembly 100 is also reduced making the design sturdy, consuming less potential energy, and avoiding any draining of the battery power. In a test conducted on the horn assembly 100, the horn assembly 100 is operating at almost double the life of a conventional housing available in the market.

[0061] While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. ,CLAIMS:1. A horn assembly (100) comprising:
