Description

Technical Field

[0001] This utility model relates to the field of locomotive starting technology, specifically to a locomotive starting switch. Background Technology

[0002] The locomotive's start switch usually controls the on / off state of the ignition circuit. After the driver inserts the key into the start switch and turns the ignition, the driver needs to press the start switch button to connect the stationary and moving contacts, thus connecting the ignition circuit.

[0003] Chinese utility model patent publication number "CN208954866U" discloses a motorcycle starter switch, including a switch housing, a button, an upper conductive post, a lower conductive post, a conical helical spring, a conductive plate, and an insulating ring. The switch housing has a receiving cavity, and the upper and lower conductive posts are located within the receiving cavity. The insulating ring is fitted onto the lower conductive post, and the conductive plate is fitted onto the insulating ring. The large end of the conical helical spring is loosely fitted onto the lower conductive post and abuts against the upper surface of the conductive plate. The small end of the conical helical spring faces upward and is fitted onto the upper conductive post. The small end of the conical helical spring abuts against a retaining ring at the upper end of the upper conductive post. The button passes through the upper part of the switch housing, and the inner end of the button abuts against or is fixed to the retaining ring.

[0004] However, in conjunction with the instruction manual appendix Figure 1 Appendix Figure 2 As can be seen from the content, the button is slidably mounted on the switch housing, with its end exposed outside the switch housing. External contaminants can easily adhere to the gap between the button and the switch housing, enter the switch housing when the button is pressed, and accumulate inside the switch housing. Liquid can also easily flow into the switch housing through the gap, corroding the upper and lower conductive posts, leading to contact failure or short circuit of the upper and lower conductive posts.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a compact and waterproof locomotive starter switch to solve the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a locomotive start switch, comprising a housing, a push-button switch, and a fixing member. The housing has an installation cavity, the push-button switch is inserted into the installation cavity, and a button opening is provided at the bottom of the installation cavity. A button cap is inserted into the button opening. The fixing member is detachably connected to the housing. The push-button switch comprises a resilient button cover, an upper button cover, a lower button cover, a moving contact, and a contact seat. The upper button cover has openings at both ends. One end of the resilient button cover is linked with the button cap, and the other end covers one opening of the upper button cover and is engaged with the upper button cover. The moving contact is inserted into the resilient button cover and is linked with the resilient button cover. The contact seat is engaged with the upper button cover. The lower button cover covers the other opening of the upper button cover opposite the resilient button cover and is detachably connected to the upper button cover.

[0008] By adopting the above technical solution: the push-button switch is installed inside the mounting cavity and linked with the button cap at the button opening. The button cap can block the button opening, reducing the amount of liquid entering from the button opening. Furthermore, the ends of the elastic button cover, upper button cover, and lower button cover are connected and sealed, which can protect the moving contact and contact seat, further improving the waterproof performance of the push-button switch. Moreover, since the locomotive start switch uses the elastic button cover to drive the moving contact to contact and separate, compared with the traditional method of using a linkage, the elastic cover significantly improves the protection capability of the moving contact and contact seat, reduces the corrosion of the moving contact and contact seat by external pollutants, effectively extends the service life of the locomotive start switch, and the overall structure is more compact and smaller in size.

[0009] The locomotive start switch described above can be further configured as follows: the inner cavity of the button cap is provided with a connecting cylinder, the elastic button cover includes an elastic protrusion and a connecting cap, the elastic protrusion passes through the connecting cylinder, the end face of the connecting cap extends outward with a connecting edge, the outer circumferential surface of the connecting edge can abut against the inner wall of the upper button cover, the bottom of the connecting cylinder is provided with a connecting post, the end of the elastic protrusion is provided with a connecting slot, and the connecting post can pass into the connecting slot.

[0010] By adopting the above technical solution: the connecting cap is snapped into the upper button cover through the connecting edge, and the elastic protrusion is inserted into the connecting cylinder of the button cap. When the button cap moves, the elastic protrusion deforms and drives the moving contact to move, so that the moving contact contacts the contact seat, thereby starting the locomotive. At the same time, the connecting post of the connecting cylinder cooperates with the connecting slot on the end face of the elastic drawing, which improves the stability of the linkage between the elastic protrusion and the button cap, prevents the elastic protrusion from shifting during the deformation process, and improves the stability of the button switch structure.

[0011] The aforementioned locomotive start switch can be further configured as follows: the upper button cover has a positioning rim extending outward from one end near the lower button cover; the lower button cover has a button groove; the positioning rim can abut against the side wall of the button groove; the outer periphery of the upper button cover has a plurality of first connecting blocks extending outward; the outer periphery of the lower button cover has a plurality of second connecting blocks extending outward; the first connecting blocks have a first connecting hole; the second connecting blocks have a second connecting hole; the first connecting blocks and the second connecting blocks overlap to make the first connecting hole and the second connecting hole located on the same central axis; and the connecting bolts pass through the first connecting hole and the second connecting hole to achieve a detachable connection between the upper button cover and the lower button cover.

[0012] By adopting the above technical solution: when assembling the upper and lower button covers, the positioning edge is first inserted into the button groove to initially fix the upper and lower button covers, and the first connecting block and the second connecting block are naturally aligned. Then, the connecting bolts are screwed into the first connecting hole and the second connecting hole to achieve a detachable connection between the upper and lower button covers, which improves the convenience of button switch assembly and maintenance.

[0013] The locomotive start switch described above can be further configured such that: the mounting cavity is provided with several mounting slots, the first connecting block and the second connecting block can be inserted into the mounting slots, the bottom of the mounting slot is provided with a third connecting hole, the first connecting hole, the second connecting hole and the third connecting hole are coaxially distributed, and the side wall of the lower button cover is provided with a wire hole in the button slot.

[0014] By adopting the above technical solution: when the push button switch is inserted into the mounting cavity, the first connecting block and the second connecting block will be inserted into the mounting groove. When the first connecting block contacts the bottom of the mounting groove, the connecting bolt is screwed into the third connecting hole, which can fix the push button switch on the housing. In addition, the wire hole on the side of the lower button cover allows the electrical connection wire of the contact seat to pass through the push button switch and be led out from the mounting cavity, making the overall structure more compact.

[0015] The aforementioned locomotive start switch can be further configured as follows: a wire-passing block extends outward from the wire-passing hole on the lower button cover, a first wire-passing groove is provided on the side of the housing, the wire-passing block passes through the first wire-passing groove, and a wire-passing protrusion extends outward from one end of the wire-passing block relative to the lower button cover towards the housing, and the wire-passing protrusion cooperates with the first wire-passing groove to fix the electrical connection wire.

[0016] By adopting the above technical solution: the wire guide block can support the electrical connection wire and prevent it from bending excessively. The electrical connection wire passes through the first wire guide groove and is led out of the housing. The wire guide protrusion presses the electrical connection wire located in the first wire guide groove into the first wire guide groove, thus binding the electrical connection wire. At the same time, it reduces the gap between the electrical connection wire and the first wire guide groove, preventing external contaminants from entering the housing from the first wire guide groove, thereby improving the stability of the locomotive starter switch structure and function.

[0017] The locomotive start switch described above can be further configured such that: a second wire-passing groove is provided in the mounting cavity connected to the side wall of the housing, and an arc-shaped support plate extends outward from the lower button cover, with the end of the arc-shaped support plate passing through the second wire-passing groove.

[0018] By adopting the above technical solution: when the electrical connection wire is led out from the wire hole into the mounting cavity, the arc-shaped support plate can support the electrical connection wire, prevent the electrical connection wire from bending excessively, and guide the direction of the electrical connection wire to prevent the electrical connection wire from deviating in the mounting cavity. At the same time, the end of the arc-shaped support plate passes through the second wire groove. When the electrical connection wire passes through the second wire groove, the arc-shaped support plate can limit the electrical connection wire to prevent the connection wire from leaving the second wire groove. In addition, the end of the arc-shaped support plate can contact the fixing component, thereby supporting the push button switch and further improving the stability of the connection between the push button switch and the housing.

[0019] The aforementioned locomotive start switch can be further configured as follows: the fixing component includes a first clamp and a second clamp, the first clamp has a first hook at one end and a first fixing plate at the other end, the second clamp has a second hook at one end and a second fixing plate at the other end, the first clamp and the second clamp are bent inward in the middle to form a first handlebar hole for the handlebar to pass through, the housing has fixing grooves on both sides, the fixing grooves are connected to the mounting cavity in the middle of the fixing grooves and have fixing slots, the first hook and the second hook can pass into the fixing slots to make the first clamp and the second clamp engage with the housing, the first fixing plate has a first fixing hole, the second fixing plate has a second fixing hole, and fixing bolts pass through the first fixing hole and the second fixing hole.

[0020] By adopting the above technical solution: the first clamp and the second clamp are engaged with the fixing groove of the housing through the first hook and the second hook, so as to realize the quick installation and disassembly of the fixing component and the housing. At the same time, the first handlebar hole can be adapted to handlebars of different sizes, improving the versatility of the locomotive start switch. The fixing bolt is inserted into the first fixing hole and the second fixing hole, so that the first clamp and the second clamp are tightly fixed to the handlebar, enhancing the stability of the locomotive start switch on the handlebar and preventing loosening.

[0021] The locomotive start switch described above can be further configured such that: a fixing ring extends outward from one end of the second fixing hole relative to the first fixing plate.

[0022] By adopting the above technical solution, the fixing ring can guide and limit the fixing bolt, making it easier for the fixing bolt to pass through the first fixing hole and the second fixing hole. At the same time, the fixing ring can increase the structural strength of the second fixing plate, prevent the fixing bolt from damaging the second fixing plate during tightening, and improve the durability and reliability of the fastener.

[0023] The locomotive start switch described above can be further configured as follows: the fixing component is a fixed bracket, the fixed bracket and the housing form a second handlebar hole, the housing has a plurality of first mounting holes facing the fixed bracket, the fixed bracket has a plurality of second mounting holes, the first mounting holes and the second mounting holes are provided with mounting bolts, and the mounting bolts are threadedly connected to the housing.

[0024] By adopting the above technical solution, the second handlebar hole is divided into two parts by a fixed bracket and a housing. During installation, the housing and the fixed bracket are located at both ends of the handlebar, and then the housing and the fixed bracket are closed. The handlebar is inserted into the second handlebar hole, and then the mounting bolts are inserted into the first mounting hole and the second mounting hole. This achieves a detachable connection between the fixed bracket and the housing and allows the locomotive start switch to be installed on the handlebar, simplifying the convenience of locomotive start switch installation.

[0025] The beneficial effects of this utility model are as follows: the push button switch can surround and protect the moving contact and contact seat through the elastic button cover, upper button cover, and lower button cover, preventing external contaminants and liquids from entering the push button switch. One end of the elastic button cover is linked to the button cap through an elastic protrusion, and the other end is detachably connected to the upper button cover through the connecting edge on the connecting cap. The moving contact is inserted into the elastic protrusion and linked with the elastic protrusion. The electrical connection wire of the contact seat passes through the button groove and is then led out from the wire hole on the side of the lower button cover. Compared with the traditional method of moving the moving contact by the button post, the push button switch structure of this application is more compact, and the elastic button cover, upper button cover, and lower button cover can provide good protection and effectively extend the service life of the push button switch.

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1: A locomotive start switch, such as Figures 1 to 6As shown, the device includes a housing 1, a push-button switch 2, and a fixing member 3. The housing 1 has a mounting cavity 11, and the push-button switch 2 is inserted into the mounting cavity 11. The bottom of the mounting cavity 11 has a button opening 12, and a button cap 4 is inserted into the button opening 12. The fixing member 3 is detachably connected to the housing 1. The push-button switch 2 includes a resilient button cover 21, an upper button cover 22, a lower button cover 23, a moving contact 24, and a contact seat 25. The upper button cover 22 has openings 221 at both ends. One end of the resilient button cover 21 is linked with the button cap 4, and the other end covers one opening 221 of the upper button cover 22 and is engaged with the upper button cover 22. The moving contact 24 is inserted into the resilient button cover 21 and is linked with the resilient button cover 21. The contact seat 25 is engaged with the upper button cover 22. The lower button cover 23 covers the other opening 221 of the upper button cover 22 opposite to the resilient button cover 21 and is detachably connected to the upper button cover 22. The push-button switch 2 is installed inside the mounting cavity 11 and is linked with the button cap 4 at the button opening 12. The button cap 4 can block the button opening 12, reducing the amount of liquid entering from the button opening 12. Furthermore, the ends of the elastic button cover 21, the upper button cover 22, and the lower button cover 23 are connected and sealed, which can protect the moving contact 24 and the contact seat 25, further improving the waterproof performance of the push-button switch 2. Since the locomotive start switch uses the elastic button cover 21 to drive the moving contact 24 to contact and separate, compared with the traditional method of using a linkage, the elastic button cover 21 significantly improves the protection capability of the moving contact 24 and the contact seat 25, reduces the corrosion of the moving contact 24 and the contact seat 25 by external pollutants, effectively extends the service life of the locomotive start switch, and the overall structure is more compact and smaller in size.

[0030] The inner cavity of the button cap 4 is provided with a connecting cylinder 41. The elastic button cover 21 includes an elastic protrusion 211 and a connecting cap 212. The elastic protrusion 211 passes through the connecting cylinder 41. The end face of the connecting cap 212 extends outward with a connecting edge 213. The outer circumferential surface of the connecting edge 213 can abut against the inner wall of the upper button cover 22. The bottom of the connecting cylinder 41 is provided with a connecting post 42. The end of the elastic protrusion 211 is provided with a connecting slot 214. The connecting post 42 can pass into the connecting slot 214. The connecting cap 212 is engaged with the upper button cover 22 via the connecting edge 213. The elastic protrusion 211 passes through the connecting cylinder 41 of the button cap 4. When the button cap 4 moves, the elastic protrusion 211 deforms and drives the moving contact 24 to move, so that the moving contact 24 contacts the contact seat 25, thereby starting the locomotive. At the same time, the connecting post 42 of the connecting cylinder 41 cooperates with the connecting slot 214 on the end face of the elastic protrusion 211, which improves the stability of the linkage between the elastic protrusion 211 and the button cap 4, prevents the elastic protrusion 211 from shifting during the deformation process, and improves the stability of the push button switch 2 structure.

[0031] The upper button cover 22 extends outward from the end near the lower button cover 23 with a positioning edge 222. The lower button cover 23 has a button groove 231. The positioning edge 222 can abut against the side wall of the button groove 231. Several first connecting blocks 223 extend outward from the outer periphery of the upper button cover 22, and several second connecting blocks 232 extend outward from the outer periphery of the lower button cover 23. The first connecting blocks 223 have first connecting holes 224, and the second connecting blocks 232 have second connecting holes 233. The first connecting blocks 223 and the second connecting blocks 232 overlap to make the first connecting holes 224 and the second connecting holes 233 located on the same central axis. The connecting bolts are inserted into the first connecting holes 224 and the second connecting holes 233 to realize the detachable connection between the upper button cover 22 and the lower button cover 23. When assembling the upper button cover 22 and the lower button cover 23, the positioning edge 222 is first inserted into the button groove 231 to initially fix the upper button cover 22 and the lower button cover 23, and the first connecting block 223 and the second connecting block 232 are naturally aligned. Then, the connecting bolts are screwed into the first connecting hole 224 and the second connecting hole 233 to achieve the detachable connection between the upper button cover 22 and the lower button cover 23, which improves the convenience of assembling and maintaining the button switch 2.

[0032] The mounting cavity 11 has several mounting slots 111, and the first connecting block 223 and the second connecting block 232 can be inserted into the mounting slots 111. A third connecting hole 112 is opened at the bottom of the mounting slot 111. The first connecting hole 224, the second connecting hole 233, and the third connecting hole 112 are coaxially distributed. The side wall of the lower button cover 23 is connected to the button slot 231 and has a wire hole 234. When the button switch 2 is inserted into the mounting cavity 11, the first connecting block 223 and the second connecting block 232 will be engaged in the mounting slot 111. When the first connecting block 223 contacts the bottom of the mounting slot 111, the connecting bolt is screwed into the third connecting hole 112, which can fix the button switch 2 on the housing 1. The wire hole 234 on the side of the lower button cover 23 allows the electrical connection wire of the contact seat 25 to pass through the button switch 2 and be led out from the mounting cavity 11, making the overall structure more compact.

[0033] A wire-passing clip 235 extends outward from the wire-passing hole 234 on the lower button cover 23. A first wire-passing groove 13 is provided on the side of the housing 1. The wire-passing clip 235 passes through the first wire-passing groove 13. A wire-passing protrusion 236 extends outward from the end of the wire-passing clip 235 relative to the lower button cover 23 towards the housing 1. The wire-passing protrusion 236 cooperates with the first wire-passing groove 13 to fix the electrical connection wire. The wire-passing clip 235 can support the electrical connection wire and prevent the electrical connection wire from bending excessively. The electrical connection wire passes through the first wire-passing groove 13 and is led out from the housing 1. The wire-passing protrusion 236 presses the electrical connection wire located in the first wire-passing groove 13 into the first wire-passing groove 13, which bundles the electrical connection wire and reduces the gap between the electrical connection wire and the first wire-passing groove 13, preventing external contaminants from entering the housing 1 from the first wire-passing groove 13, thereby improving the stability of the locomotive starter switch structure and function.

[0034] The fastener 3 includes a first clamp 31 and a second clamp 32. The first clamp 31 has a first hook 311 at one end and a first fixing plate 312 at the other end. The second clamp 32 has a second hook 321 at one end and a second fixing plate 322 at the other end. The first clamp 31 and the second clamp 32 are bent inward in the middle to form a first handlebar hole for the handlebar to pass through. The housing 1 has fixing grooves 15 on both sides. The fixing grooves 15 are connected to the mounting cavity 11 in the middle and have a fixing slot 151. The first hook 311 and the second hook 321 can pass into the fixing slot 151, so that the first clamp 31 and the second clamp 32 are engaged with the housing 1. The first fixing plate 312 has a first fixing hole 313 and the second fixing plate 322 has a second fixing hole 323. Fixing bolts are inserted into the first fixing hole 313 and the second fixing hole 323. The first clamp 31 and the second clamp 32 are engaged with the fixing groove 151 of the housing 1 through the first hook 311 and the second hook 321, so as to realize the quick installation and disassembly of the fixing part 3 and the housing 1. At the same time, the first handlebar hole can be adapted to handlebars of different sizes, improving the versatility of the locomotive start switch. The fixing bolt is inserted into the first fixing hole 313 and the second fixing hole 323, so that the first clamp 31 and the second clamp 32 tightly fix the handlebar, enhance the stability of the locomotive start switch on the handlebar, and prevent loosening.

[0035] A retaining ring 324 extends outward from the end of the second fixing hole 323 relative to the first fixing plate 312. The retaining ring 324 guides and limits the fixing bolt, making it easier for the fixing bolt to pass through the first fixing hole 313 and the second fixing hole 323. At the same time, the retaining ring 324 increases the structural strength of the second fixing plate 322, prevents the fixing bolt from damaging the second fixing plate 322 during tightening, and improves the durability and reliability of the fastener 3.

[0036] Example 2: The difference between Example 2 and Example 1 is that a locomotive start switch, such as... Figures 7 to 9 As shown, the fixing component 3 is a fixing bracket 33. The fixing bracket 33 and the housing 1 form a second handlebar hole. The housing 1 has several first mounting holes 16 facing the fixing bracket 33, and the fixing bracket 33 has several second mounting holes 331. Mounting bolts 332 pass through the first mounting holes 16 and the second mounting holes 331, and the mounting bolts 332 are threaded to the housing 1. The fixing bracket 33 and the housing 1 divide the second handlebar hole into two parts. During installation, the housing 1 and the fixing bracket 33 are located at both ends of the handlebar. Then, the housing 1 and the fixing bracket 33 are closed, and the handlebar is inserted into the second handlebar hole. Subsequently, the mounting bolts 332 are inserted into the first mounting holes 16 and the second mounting holes 331, which realizes the detachable connection between the fixing bracket 33 and the housing 1 and installs the locomotive start switch on the handlebar, simplifying the convenience of locomotive start switch installation.

[0037] Example 3: The difference between Example 3 and Example 2 is that a locomotive start switch, such as... Figures 10 to 12 As shown, a second wire-passing groove 14 is provided on the side wall of the housing 1, which connects to the mounting cavity 11. An arc-shaped support plate 237 extends outward from the lower button cover 23, with the end of the arc-shaped support plate 237 passing through the second wire-passing groove 14. When the electrical connection wire is led out from the wire-passing hole 234 into the mounting cavity 11, the arc-shaped support plate 237 can support the electrical connection wire, prevent the electrical connection wire from bending excessively, and guide the direction of the electrical connection wire, preventing the electrical connection wire from deviating within the mounting cavity 11. At the same time, when the electrical connection wire passes through the second wire-passing groove 14, the arc-shaped support plate 237 can limit the electrical connection wire, preventing the electrical connection wire from detaching from the second wire-passing groove 14. In addition, the end of the arc-shaped support plate 237 can contact the fixing member 3, thereby supporting the button switch 2 and further improving the stability of the connection between the button switch 2 and the housing 1.
