DESC:A SWITCH ASSEMBLY FOR A VEHICLE

FIELD OF THE INVENTION

The present disclosure relates to a switch assembly of a vehicle. Particularly, the present disclosure relates to a water-proof switch assembly for vehicles.

BACKGROUND OF THE INVENTION

Electronic switches are employed in vehicles to execute an electronic operation in the vehicle, such as operating the vehicle’s headlight or occupant’s seat. The electronic switches have a printed circuit board that has an electronic circuit and tact switches adapted to selectively open or close the electronic circuit. The tact switches are operated by a knob, and the knob is adapted to be operated by a user. Further, the components of the electronic switches are packed inside a housing which is further installed inside the vehicle.

One type of an electronic switch or a control knob is disclosed in a Japanese patent JPH0676694A (‘964 patent) to prevent backlash. The control knob has a shaft erected on a slider which is operatively connected to an actuator of a switch body and fitted connecting the shaft to a fitting hole formed in the operation knob. The operation knob is in a direction perpendicular to a shaft axis direction displacement the slider a switching device configured to slide operated by the switch body is by the rubber pieces which are interposed in the gap between the fitting hole formed in the tip and the operation knob of the shaft body.

Another type of an electronic switch or a key assembly is taught in a WIPO publication WO2020087375A1 (‘375 publication) that has a housing, a trigger button, an elastic button cap, and a button. Further, the key assembly is designed to reduce abnormal sound and poor hand feel of the key. The key assembly is assembled in such a way that the button actuates the button cap which further pushes the trigger button. Further, the key assembly has light guides to provide a visual marker for the user.

There are some limitations associated with current electronic switches. The electronic switches, for instance, are susceptible to water ingress which can tamper with the operation of the electronic circuit. One way to mitigate this issue is to apply a sealant to prevent the ingress of water. Moreover, the sealant is also prone to failure which can cause leakage.

In addition, the electronic switch has a limited contact area for actuation by the user which can limit the instance of actuation in case the user does not press the switch correctly. In addition, the electronic switch uses plastic switch covers which are prone to damage in cases where the user does not correctly push the electric switch.

Accordingly, there is a need for a switch assembly that overcomes the above-mentioned limitations.

SUMMARY OF THE INVENTION

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 and nor is it intended for determining the scope of the invention.

The present subject matter relates to the aspects of a water-proof switch that can be installed in the vehicle. The water-proof switch has a rubber enclosure in which the PCB is installed in such a way that the ingress of water is prevented.

In an embodiment, a water-proof switch is disclosed that has a rubber disclosure which accommodates the switch assembly and acts as a switch for the user to actuate. The water-proof switch also includes a carrier, which is installed in a cavity created by the rubber disclosure. The carrier is designed to hold a printable circuit board (PCB) in place and a periphery of the carrier overlaps a first surface of a set of inner flanges. Further, a cover is placed over the cavity containing the PCB, wherein a periphery of the cover overlaps a second surface of the set of inner flanges. The set of inner flanges is placed such that the peripheries of the cover and the carrier sandwich the set of inner flanges.

A method of assembly of the switch assembly contains mounting of the PCB on a carrier, which forms a carrier sub-assembly. The carrier sub-assembly is then placed inside the rubber enclosure which has the set of inner flanges designed with lips. The carrier overlaps the first surface of the set of inner flanges and lips. The assembly thus formed is called a carrier enclosure sub-assembly. The cover is mounted over the carrier enclosure sub-assembly, wherein the cover overlaps the second surface of the set of inner flanges and lips thus sandwiching the set of inner flanges between the carrier and the cover.

In comparison to the switch body taught in the ‘964 patent, the water-proof switch has a soft rubber material which encapsulates the whole switch. Moreover, in comparison to the switch body of the ‘964 patent, the water-proof switch provides a larger space for pressing the register the operation of the switch. In addition, the water-proof switch because the water-proof switch uses a potting material which makes the water-proof switch rated for IP-67 waterproof rating. In addition, the water-proof switch also provides a visual signal in the form of an LED embedded in the rubber enclosure.

Further, in comparison to the button assembly of the of ‘375 publication, the water-proof switch provides protection against dirt and water which is not available in the button assembly of the ‘375 publication thereby making the water-proof switch suitable for automotive seats. Moreover, the portion of the rubber enclosure facing the user is soft thereby making the water-proof switch ergonomic to use. Moreover, unlike the button assembly of the ‘375 publication, the water-proof switch does not require light guides thereby making the assembly of the water-proof switch simpler. In contrast, the water-proof switch Special feature is used to avoid mixing of light from multiple different color LEDs.

According to the present subject matter, the rubber enclosure prevents seepage of water to the PCB thereby ensuring that the PCB is protected from short circuits caused by seepage. Moreover, the rubber enclosure and the plastic support ensure that the pressing of the rubber enclosure in any way results in the closing or opening of the electronic circuit thereby ensuring the operation of the electronic components operated by the electronic circuit.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Figures 1, 2 and 3 illustrate different aspects of a switch assembly 100, according to an embodiment of the present disclosure. The switch assembly 100 is hereon further referred to as a water-proof switch 100. Specifically, Figure 1 illustrates an assembled view of the water-proof switch 100 while Figure 2 shows an exploded view of the water-proof switch 100 and Figure 3 illustrates a cross-section of the water-proof switch 100. The water-proof switch 100 may be used in an automobile to operate an electronic component. Alternatively, the water-proof switch 100 may be used on an electronic appliance to, for instance, switch OFF/ON the electronic appliance. The water-proof switch 100 is designed in such a way that the water-proof switch 100 allows the user to actuate the electronic component/ appliance, no matter how the user operates the water-proof switch 100. Moreover, the water-proof switch 100 prevents ingress of water thereby protecting the internal components of the water-proof switch 100. The water-proof switch 100 may include, but is not limited to, a rubber enclosure 102, a plastic support 104, a brass insert 106, a carrier 108, a printed circuit board (PCB) 110, a cover 112, a potting material 114, and a pair of screws 116.

As shown in Figures 2 and 3, the rubber enclosure 102 forms the outermost layer of the water-proof switch 100, which has been designed to prevent the ingress of water and with a cavity 118 to incorporate the consequent parts of the water-proof switch 100. The plastic support 104 is placed inside the rubber enclosure 102 which helps with the actuation of a tact switch 126 placed on the PCB 110. The carrier 108 is placed above the plastic support 104, as the carrier 108 is designed to hold the PCB 110, which is secured in place using the brass inserts 106. Further, the PCB 110 is placed in the carrier 108 and is covered using the cover 112, which is secured using a pair of screws 116. Furthermore, the potting material 114 is poured onto the cover 112, thus forming a complete assembly of the water-proof switch 100. Further, details of each component are provided with respect to their individual figures.

Figures 4, 5 and 6 illustrate the various forms of the rubber enclosure, according to an embodiment of the present disclosure. Specifically, Figure 4 illustrates the rubber enclosure with ribs, while Figure 5 illustrates a flange structure incorporated to be used for sewing the water-proof switch to the seat, and Figure 6 illustrates the flange structure incorporated for screwing purposes.

The rubber enclosure 102 forms a major portion of the water-proof switch 100. The rubber enclosure 102 is a single-piece component and includes a cavity 118 which houses other components of the rubber enclosure 102. The rubber enclosure 102 also includes an outer surface 102A facing outside and an inner surface 102B which faces the cavity 118. The rubber enclosure 102 also includes protrusions 120 extending from the inner surface 102B into the cavity 118. The rubber enclosure 102 also includes a pair of outer flanges 122 that extend from all the sides of the rubber enclosure 102. The outer flanges 122 allow mounting of the rubber enclosure 102 on a platform, such as a dashboard or a seat. The outer flanges 122 either mount the rubber enclosure 102 on the platform either by fastening or by sewing. The outer flanges 122 are made of the same material as the rest of the rubber enclosure 102. The rubber enclosure 102 also includes a lip 124 that extend from the tips of a set of inner flanges 138 of the rubber enclosure 102 inwardly. The lip 124 along with the set of inner flanges 138 are sandwiched between the peripheries of the cover 112 and the carrier 108 thereby securing the rubber enclosure 102. Moreover, the lip 124 prevent the ingress of water or dust into the rubber enclosure 102.

As shown in Figure 4, in an embodiment, the rubber enclosure 102 also includes a plurality of supporting ribs 136. The plurality of supporting ribs 136 are incorporated into the rubber enclosure 102 in order to provide support to the plastic support 104 and hold the assembly of the water-proof switch 100 in place.

As shown in Figure 5, in an embodiment, the outer flanges 122 are suitable for sewing the rubber enclosure 102 onto a two-wheeler vehicle. The outer flanges 122 are designed around the periphery of the rubber enclosure 102 which allows the rubber enclosure 102 and therefore, the water-proof switch 100 to be sewn onto the seat or any other soft surfaces of the two-wheeler vehicle.

As shown in Figure 6, in another embodiment, the outer flanges 122 are suitable for screwing the rubber enclosure 102 onto the two-wheeler vehicle. The outer flanges 122 are designed on at least two of opposite sides of the rubber enclosure 102. Each of the flange 122 has a perforation for installing the rubber enclosure 102 and the water-proof switch 100 onto the two-wheeler vehicle using an another pair of screws.

Details of the plastic support 104 are now provided with respect to Figures 7 and 8 in conjunction with Figure 2 and 3. Specifically, Figure 7 illustrates plastic supports with a bridge, while Figure 8 illustrates the plastic supports without the bridge.

The plastic support 104 is installed in the cavity 118 (also shown in Figure 3). The plastic support 104 is made of robust materials like Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) blend. The plastic support 104 has a predefined profile on a bottom section 104A of the plastic support 104 which faces the PCB 110. The plastic support 104 also has an upper section 104B which faces the base of the rubber enclosure 102. The plastic support 104 is designed to install on the PCB 110 to transfer the input from the rubber enclosure 102 to the PCB 110. In one example, the plastic support 104 is adapted to make contact tact switches 126 of the PCB 110. The plastic support 104 is designed in such a way that the bottom section 104A of the plastic support 104 has a similar surface attribute as the inner surface 102B to correctly transfer the input from the outer surface 102A to the PCB 110. For instance, the input received on the right section R 702 of the outer surface 102A may cause the corresponding area of the bottom section 104A to depress which, in turn, presses the tact switch 126. Similarly, the inputs received on the left section L 704 of the outer surface 102A may cause the corresponding area of the bottom section 104A to depress which, in turn, presses the tact switch 126. In either case, pressing at any place of the rubber enclosure 102 is translated into the pressing of the tact switch 126 thereby ensuring the execution of the electronic operation.

In one example, as shown in Figure 7, the plastic support 104 is constructed with a bridge 706 between the right section R 702 and the left section L 704. The bridge 706, helps in easing the actuation of the switch, as either pressing the right section R 702 or the left section L 704 actuates the switch by added pressure.

In another example, as shown in figure 8, in another embodiment, the plastic support 104 is constructed without the bridge between the right section R and left section L. The additional bridge between the plastic supports 104 in which scenarios, these supports can be used. For instance, the plastic support 104 with the bridge may be used when the switches are spaced apart whereas the plastic support 104 without the bridge can be used when the switches are placed near to each other to prevent unwanted actuation.

Figure 9 illustrates a sub-assembly of the plastic support 104 and the rubber enclosure 102, according to an embodiment of the present disclosure. The plastic support 104 and the rubber enclosure 102 are designed to provide a visual indication for the user. An exemplary embodiment is shown in Figure 9 which shows different views of a sub-assembly 900 of the rubber enclosure 102 and the plastic support 104. Specifically, (A) of Figure 9 shows the plastic support 104 and (B) of Figure 9 shows a back view of the sub-assembly 900. Further, (C) of Figure 9 shows a front view of the sub-assembly 900 with partially visible plastic support 104 installed in the rubber enclosure 102.

As shown in (A) of Figure 9, the plastic support 104 has one or more holes 130 to house an LED. Further, the rubber enclosure 102 is designed in such a way that the light may pass through from the rubber enclosure 102. In one example, the LED can be operated by the tact switch 126, such that the LED turn ON when the tact switch 126 is operated. The plastic support 104 also includes a plurality of openings 132 that receives a plurality of raised sections 134 of the rubber enclosure 102 as shown in Figure 9(B). The raised sections 134 may have a height greater than a height of the LED, such that the raised section 134 completely blocks the lights from spreading inside the sub-assembly 900. As a result, the light from the LED installed in the right-side hole 130 does not mix with the light from the LED installed in the left-side hole 130. Thus, the raised sections 134 prevent the mixing of the light while the outer surface 102A allows parts of the light to pass through thereby illuminating the outer surface 102A.

Figures 10 and 11 illustrate the various forms of the carrier 108, according to an embodiment of the present disclosure. Specifically, Figure 10 illustrates the carrier with a support structure, while Figure 11 illustrates the carrier without the support structure.

The plastic support 104 is supported on the carrier 108 using the pair of brass inserts 106 so that the plastic support 104 does not collapse on the carrier 108. Further, the carrier 108 is designed to secure the PCB 110 in the rubber enclosure 102. Furthermore, the carrier 108 also facilitates quick assembly and disassembly of the PCB 110 from the rubber enclosure 102 in case of replacement. The carrier 108 may include a seat in which the PCB 110 can be installed. In one example, the carrier 108 may secure the PCB 110 using fasteners or snap locks. In either case, the PCB 110 is firmly secured to the carrier 108.

In one example, as shown in Figure 10, the carrier 108 is designed with a support structure around the periphery of the carrier 108. The support structure is added to provide additional support and holding capacity for the PCB 110 and the cover 112. Further, the corners have a small radius used and a sharp point around the edges of the carrier 108, thus using a small radius of another pair of screws in order to fasten the assembly.

As shown in Figure 11, in another embodiment, the carrier 108 is designed without the support structure but within the rubber part instead of the plastic part, providing additional space for the placement of the PCB 110 and the cover 112. Further, the radius at the end across the end of the carrier 108 provides better placement and area for bigger radius of another pair of screws.

The PCB 110 may include electronic circuits thereon to operate the electronic component. The PCB 110 also includes tact switches 126 which, when pressed by the plastic support 104 either closes or opens the electronic circuit.

In one example, the cover 112 is installed over the carrier 108 as shown in Figure 1. In one example, the cover 112 is secured to the rubber enclosure 102 using the pair of screws 116. Further, the cover 112 has extensions 112A that may sit on the lip 124. Further, the rubber enclosure 102 may include a step profile adapted to receive the plastic support 104 and at least one tact switch 126. The cover 112 may include an opening 128 which provides access to the PCB 110. The opening 128 along with the base of the PCB 110 forms a vessel to receive the potting material 114. The potting material 114 is applied to the surface facing the opening 128 to protect the PCB 110 from heat, chemicals, and water, among other examples. As a result, the rubber enclosure 102 and the potting material 114 protect the PCB 110 from water seepage.

Referring now to Figures 12A and 12B which show a method 1200 of assembling the water-proof switch 100, according to an embodiment of the present disclosure. The order in which the method steps are described below is not intended to be construed as a limitation, and any number of the described method steps can be combined in any appropriate order to execute the method or an alternative method. Additionally, individual steps may be deleted from the method without departing from the spirit and scope of the subject matter described herein.

The method 1200 begins at step 1202 in which the carrier 108 is placed on an assembly platform and the PCB 110 is installed in the carrier 108 to form a first sub-assembly 1300. Thereafter, at step 1204, the first sub-assembly 1300 is installed in the rubber enclosure 102 so that periphery of the carrier 108 overlaps a first surface of the set of inner flanges 138 to form a second enclosure sub-assembly 1302. In one example, the first sub-assembly 1300 is pressed into the cavity 118 of the rubber enclosure 102 so that the periphery of the carrier 108 push against the lip 124 of the inner flanges 138 causing them to buckle. Further pressing of the carrier 108 results in the lip 124 to come to return to their original posture the edges of the carrier 108 are pushed underneath the lip 124. As a result, a second sub-assembly 1302 is formed.

Further, at step 1206, the cover 112 is installed in the second sub-assembly 1302 by fastening the cover 112 to form a third sub-assembly 1304. Further, at step 1208, the third sub-assembly 1304 is further assembled by fastening the cover 112 to the second sub-assembly 1302 using the pair of screws 116 to form the third sub-assembly 1304. Finally, at step 1210, the potting material 114 is poured in the fourth sub-assembly 1306 to form the water-proof switch 100.

According to the present disclosure, the rubber enclosure 102 and the plastic support 104 provide a large surface for a defined size of the water-proof switch 100 thereby making the pressing of the water-proof switch 100 more accurate than currently known switches. Moreover, since the rubber enclosure 102 encapsulates the PCB 110 and the potting material 114 seals the remainder of the exposed parts of the PCB 110, the PCB 110 is protected from water and dust.

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.
