Description

Technical Field

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

[0002] Most motorcycles are turned off by turning the key on the ignition lock. To restart the engine, the key must be turned in the opposite direction before the engine start switch is pressed. For motorcycle riders, this means that their right hand has to move back and forth between the handlebars and the ignition lock during the engine shutdown and start-up process, which is cumbersome and inconvenient and not ideal.

[0003] Chinese utility model patent publication number "CN213109644U" discloses a handle switch assembly, including a housing, an inner seat, and switch units; the inner seat is fixed inside the housing, and a plurality of switch units are mounted on the inner seat; operation keys are mounted on the housing at positions corresponding to each switch unit; each switch unit includes at least a seat heating switch for controlling the on / off state of the seat heater; a steering wheel cover heating switch for controlling the on / off state of the steering wheel cover heater; a light switch for controlling the on / off state of the light; and a start / stop switch for controlling the start and stop of the vehicle.

[0004] However, the above-mentioned handle switch assembly still has the following defects: First, according to paragraphs

[0034] and

[0046] of its instruction manual, the start-stop switch includes a start switch and a stop switch. Pressing forward starts the locomotive, and pressing backward stops the locomotive. That is, the start-stop switch is a toggle button switch. However, this type of start-stop switch is prone to loosening during use, which may lead to accidental activation of one button, resulting in accidental shutdown or start of the locomotive due to misoperation, which poses a high safety risk.

[0005] Secondly, the ignition stop switch is a push-button switch. When the toggle switch is loose, the locomotive vibration causes the toggle switch to press the ignition stop switch, resulting in the locomotive stalling during operation, which cannot guarantee the safety of the locomotive.

[0006] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0007] The purpose of this invention is to provide a locomotive switch assembly with separate switch components and higher safety.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a locomotive switch assembly, including a housing, a start switch, an ignition stop switch, and a toggle switch. A first handlebar hole and a second handlebar hole are provided on both sides of the housing, connecting to the inner cavity of the housing. A wire hole is also provided on the side of the housing near the first handlebar hole, and an ignition switch cavity is provided on the side of the housing near the second handlebar hole. The characteristic feature is that an ignition stop hole is provided at the top of the housing, through which the ignition stop switch passes. An start hole is provided at the bottom of the housing, through which the start switch passes. The ignition stop switch includes an ignition stop mounting base, a handle, a rotor, and an ignition stop contact seat. The ignition stop mounting base is detachably connected to the housing. An ignition stop rotating hole is provided in the middle of the ignition stop mounting base. The rotor is rotatably disposed within the ignition stop rotating hole. The handle is rotatably engaged with one end of the ignition stop mounting base, and the ignition stop contact seat is engaged with the other end of the ignition stop mounting base. One end of the rotor is linked to the handle, and the other end abuts against the ignition stop contact seat.

[0009] By adopting the above technical solution: the ignition stop switch drives the rotor to rotate in the ignition stop hole through the rotation of the handle, thereby controlling the contact state of the ignition stop contact seat, realizing the stable triggering of the ignition stop function, avoiding the misoperation caused by vibration of traditional push-button switches, and improving the safety of locomotive operation. At the same time, the start switch is independently set at the bottom of the housing, separated from the ignition stop switch, further reducing the risk of accidental contact, making the locomotive start and stop operations more reliable and convenient.

[0010] The aforementioned locomotive switch assembly can be further configured as follows: a plurality of mounting plates extend outward from the outer periphery of the ignition stop mounting base near the ignition stop contact base; the ends of the mounting plates are bent to form mounting supports; a first mounting ear is provided on the mounting supports; a plurality of first mounting posts are provided inside the housing; the mounting supports are in contact with the end faces of the first mounting posts and the first mounting ears are aligned with the end faces of the first mounting posts; the end faces of the first mounting posts are also provided with positioning grooves; and the ends of the mounting supports can be inserted into the positioning grooves.

[0011] By adopting the above technical solution, the end face of the mounting plate and the first mounting post are in contact and fitted, and the first mounting ear and the positioning groove are precisely aligned, so that the flameout mounting seat can be quickly positioned and securely installed in the housing. This effectively prevents the flameout mounting seat from shifting or loosening during operation, and ensures the accuracy of the contact position between the rotor and the flameout contact seat. At the same time, the bolts passing through the first mounting ear and connecting to the first mounting post make disassembly and maintenance more convenient, and improve the overall structural stability and assembly efficiency of the switch assembly.

[0012] The aforementioned locomotive switch assembly can be further configured as follows: the side wall of the extinguishing mounting base near the extinguishing contact seat is provided with several fixing holes connected to the extinguishing rotating hole; several fixing blocks extend outward from the outer periphery of the extinguishing contact seat; the fixing blocks can be inserted into the fixing holes to achieve the engagement between the extinguishing contact seat and the extinguishing mounting base; several limiting plates extend outward from the outer periphery of the extinguishing mounting base near the fixing holes; the limiting plates can contact the outer surface of the fixing blocks; several positioning notches are also provided at the end of the extinguishing mounting base; positioning protrusions are provided on the periphery of the extinguishing contact seat; the positioning protrusions pass through the positioning notches and contact the bottom of the positioning notches.

[0013] By adopting the above technical solution: the tight fit between the fixing block and the fixing hole enables the flameout contact seat to be quickly and accurately positioned and radially fixed on the flameout mounting base; the contact between the limiting support plate and the outer surface of the fixing block effectively restricts the axial displacement of the flameout contact seat, preventing it from loosening under vibration; and the limiting support plate can prevent the flameout mounting base from coming out of the flameout through hole, further improving the stability of the flameout switch and housing assembly; at the same time, the fitting contact between the positioning protrusion and the positioning notch further ensures the relative positional accuracy of the flameout contact seat and the flameout mounting base in the circumferential direction, so that the electrical contact between the rotor and the flameout contact seat always remains stable and reliable, thereby improving the overall structural rigidity and operational consistency of the flameout switch and extending its service life.

[0014] The locomotive switch assembly described above can be further configured as follows: a moving contact is provided through the rotor, the rotor has an opening in the receiving cavity, the moving contact covers one end of the receiving cavity, and an elastic stop member is provided through the other end of the receiving cavity, a stop spring is provided between the elastic stop member and the moving contact, a plurality of stop slots are provided in the extinguishing mounting base, the rotation of the rotor causes the stop member to disengage or slide into the stop slot, the extinguishing contact plate seat is provided with a first stationary contact and a second stationary contact, the moving contact can contact the first stationary contact and the second stationary contact to realize the locomotive extinguishing, the end of the second stationary contact extends to both sides with a first contact plate and a second contact plate, the first contact plate, the second contact plate and the second stationary contact are Y-shaped, the rotation of the rotor causes the moving contact to rotate around the central axis of the rotor, causing the moving contact to connect or disconnect the first stationary contact and the first contact plate, and the first stationary contact and the second contact plate.

[0015] By adopting the above technical solution: when the rotor is in the initial position, the moving contact only contacts the first stationary contact. When the rotor rotates, the elastic stop piece slides out of the first stop slot. When the stop piece slides into the next stop slot, one end of the moving contact contacts the first stationary contact, and the other end contacts the first contact plate or the second contact plate, thereby controlling the locomotive to shut down. The stop piece and the stop slot provide clear positioning feedback, effectively preventing the switch from drifting or malfunctioning due to vibration. In addition, the Y-shaped second stationary contact allows the rotor to rotate to both sides, improving the anti-interference capability and action consistency of the shutdown switch under complex working conditions.

[0016] The above-mentioned locomotive switch assembly can be further configured as follows: the rotor also includes a square rotating column, the rotating handle has a square locking hole, the square rotating column passes through the square locking hole, the side wall of the square locking hole has a number of limiting locking grooves, the outer circumferential surface of the square rotating column has a number of limiting buckles, the limiting buckles pass through the limiting locking grooves, and the middle of the square rotating column has a deformation hole.

[0017] By adopting the above technical solution, the cooperation between the square rotating column and the square locking hole ensures the accuracy and synchronization of torque transmission between the rotating handle and the rotor. The cooperation between the limiting buckle and the limiting slot effectively prevents the axial movement and circumferential free travel of the rotating handle on the rotor, improving the operating feel and control precision. At the same time, the deformation hole in the middle of the square rotating column gives it a certain elastic deformation capability during assembly, which not only facilitates the smooth insertion of the limiting buckle into the limiting slot for quick assembly, but also maintains a tight fit with the rotating handle after assembly through elastic restoring force. This enhances the stability and durability of the rotor and rotating handle connection structure and reduces the risk of loosening due to vibration during long-term use.

[0018] The aforementioned locomotive switch assembly can be further configured as follows: a shutdown end cover is provided at one end of the handle relative to the rotor, the shutdown end cover is detachably connected to the handle, a support protrusion extends outward from the periphery of the shutdown through hole in the housing, the support protrusion has a rotation groove, the drive block of the shutdown end cover passes through the rotation groove, the shutdown end cover has several connecting buckles, the handle has several connecting slots, the connecting buckles pass through the connecting slots to realize the detachable connection between the shutdown end cover and the handle, a positioning groove is provided on the side of the handle, a positioning protrusion is provided on the side of the shutdown end cover, and the positioning protrusion can pass through the positioning groove.

[0019] By adopting the above technical solution: the flameout end cover achieves quick assembly and disassembly with the handle through the cooperation of the connecting buckle and the connecting slot, which facilitates the maintenance and replacement of internal components. The positioning convex plate and positioning groove ensure the precise positioning of the flameout end cover on the handle, effectively preventing relative rotation. The rotation groove on the supporting convex ring provides a stable rotation track for the drive block of the flameout end cover, so that the handle can rotate smoothly during operation. At the same time, the tight fit between the flameout end cover and the supporting convex ring forms an effective dynamic seal, preventing external contaminants and liquids from entering the switch, which significantly improves the protection level and service life of the flameout switch in complex environments.

[0020] The aforementioned locomotive switch assembly can be further configured as follows: the housing is divided into an upper housing and a lower housing, the upper housing is provided with a plurality of first connecting holes, the lower housing is provided with a plurality of second connecting holes, the first connecting holes and the second connecting holes are coaxially distributed, the inner cavity of the lower housing is covered with a cover plate, the lower housing is provided with a plurality of second mounting posts, the cover plate is provided with second mounting ears, the second mounting ears and the second mounting posts are detachably connected to the lower housing by mounting bolts, and the cover plate extends outward from the side near the wire hole with a limiting protrusion, the limiting protrusion passing through the wire hole.

[0021] By adopting the above technical solution, the housing and the lower housing are aligned and assembled through the corresponding first and second connecting holes, making the housing assembly process more convenient and reliable. The cover plate achieves a stable connection with the lower housing through the cooperation of the second mounting ear and the second mounting post, effectively improving the protection performance of the internal components. At the same time, the limiting protrusion and the wire hole not only provide a precise positioning reference for the cover plate to prevent it from shifting under vibration, but also significantly reduce the assembly gap at the wire hole, enhance the overall sealing of this part, and create a more reliable protective environment for the installation and fixation of cables.

[0022] The aforementioned locomotive switch assembly can be further configured such that: the limiting protrusion has a first locking tooth on the side facing the lower housing, and the bottom of the wire hole has a second locking tooth.

[0023] By adopting the above technical solution, the first and second locking teeth can make the wire harness in the wire hole more concentrated. At the same time, the first and second locking teeth can limit the electrical connection wires and allow the electrical connection wires to pass into the grooves of the first and second locking teeth, thereby making the wire harness neater. They also shield the wire hole to prevent external contaminants from entering the lower housing through the wire hole and affecting the toggle switch and start switch, thus improving the stability of the functions of each switch in the locomotive switch assembly.

[0024] The beneficial effects of this utility model are as follows: By setting the start switch and the stop switch on the upper and lower sides of the housing respectively, compared with the existing technology of controlling the start and stop of the locomotive by using a single start and stop switch, the structure of the start switch and stop switch being set separately has higher stability. Furthermore, the stop switch drives the rotor to rotate through the handle, so that the moving contact connects the first stationary contact and the second stationary contact, thereby controlling the locomotive to stop. At the same time, the first contact plate and the second contact plate extend from both sides of the first stationary contact, so that the locomotive can be stopped by rotating the handle from the middle to both sides. This improves the anti-interference ability and action consistency of the stop switch under complex working conditions.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0027] 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.

[0028] A locomotive switch assembly, such as Figures 1 to 10 As shown, the device includes a housing 1, a start switch 2, an off switch 3, and a toggle switch 4. A first handlebar hole 11 and a second handlebar hole 12 are provided on both sides of the housing 1, connecting to the inner cavity of the housing 1. A wire hole 111 is also provided on the side of the housing 1 near the first handlebar hole 11. An ignition switch cavity 13 is provided on the side of the housing 1 near the second handlebar hole 12. An off switch 3 is inserted through an off switch hole 14 at the top of the housing 1. A start switch 3 is inserted through an off switch hole 14 at the bottom of the housing 1. Within the start-up through-hole 15, the ignition stop switch 3 includes an ignition stop mounting base 31, a handle 32, a rotor 33, and an ignition stop contact seat 34. The ignition stop mounting base 31 is detachably connected to the housing 1. An ignition stop rotating hole is provided in the middle of the ignition stop mounting base 31, and the rotor 33 is rotatably disposed within the ignition stop rotating hole. The handle 32 is rotatably engaged with one end of the ignition stop mounting base 31, and the ignition stop contact seat 34 is engaged with the other end of the ignition stop mounting base 31. One end of the rotor 33 is linked with the handle 32, and the other end abuts against the ignition stop contact seat 34. The ignition stop switch 3 drives the rotor 33 to rotate within the ignition stop rotating hole through the rotation of the handle 32, thereby controlling the contact state of the ignition stop contact seat 34. This achieves stable triggering of the ignition stop function, avoiding misoperation caused by vibration of traditional push-button switches, and improving the safety of locomotive operation. At the same time, the start switch 2 is independently disposed below the housing 1, separate from the ignition stop switch 3, further reducing the risk of accidental activation and making locomotive start-up and ignition stop operations more reliable and convenient.

[0029] like Figures 2 to 4 As shown, the housing 1 is divided into an upper housing 16 and a lower housing 17. The upper housing 16 is provided with a number of first connecting holes 161, and the lower housing 17 is provided with a number of second connecting holes 171. The first connecting holes 161 and the second connecting holes 171 are coaxially distributed. The upper housing 16 and the lower housing 17 are aligned and assembled through the corresponding first connecting holes 161 and second connecting holes 171, making the assembly process of the housing 1 more convenient and reliable.

[0030] like Figures 5 to 7As shown, the flameout mounting base 31 has several mounting plates 311 extending outward from the outer periphery of one end near the flameout contact plate base 34. The ends of the mounting plates 311 are bent to form mounting support plates 312. The mounting support plates 312 are provided with first mounting ears 313. The housing 1 has several first mounting posts 162, which are distributed in the upper housing 16. The mounting support plates 312 are in contact with the end faces of the first mounting posts 162, and the first mounting ears 313 are aligned with the end faces of the first mounting posts 162. The end faces of the first mounting posts 162 are also provided with positioning grooves 163, and the ends of the mounting support plates 312 can be inserted into the positioning grooves 163. The mounting plate 312 contacts and engages with the end face of the first mounting post 162. Through the precise alignment of the first mounting ear 313 with the positioning groove 163, the flameout mounting base 31 is quickly positioned and securely installed in the housing 1. This effectively prevents the flameout mounting base 31 from shifting or loosening during operation, ensuring the accuracy of the contact position between the rotor 33 and the flameout contact plate seat 34. At the same time, the connection between the first mounting ear 313 and the first mounting post 162 via bolts makes disassembly and maintenance more convenient, improving the overall structural stability and assembly efficiency of the switch assembly.

[0031] The flameout mounting base 31 has several fixing holes 314 on one side wall near the flameout contact plate base 34, which is connected to the flameout rotating hole. Several fixing blocks 341 extend outward from the outer periphery of the flameout contact plate base 34. The fixing blocks 341 can be inserted into the fixing holes 314 to achieve the engagement between the flameout contact plate base 34 and the flameout mounting base 31. Several limiting plates 315 extend outward from the outer periphery of the flameout mounting base 31 near the fixing holes 314. The limiting plates 315 can contact the outer surface of the fixing blocks 341. Several positioning notches 316 are also provided at the end of the flameout mounting base 31. Positioning protrusions 342 are provided on the periphery of the flameout contact plate base 34. The positioning protrusions 342 pass through the positioning notches 316 and contact the bottom of the positioning notches 316. The tight fit between the fixing block 341 and the fixing hole 314 enables the flameout contact seat 34 to be quickly and accurately positioned and radially fixed on the flameout mounting base 31. The contact between the limiting plate 315 and the outer surface of the fixing block 341 effectively restricts the axial displacement of the flameout contact seat 34, preventing it from loosening under vibration. Furthermore, the limiting plate 315 prevents the flameout mounting base 31 from coming out of the flameout through hole 14, further improving the stability of the flameout switch 3 and the housing 1 assembly. At the same time, the engagement contact between the positioning protrusion 342 and the positioning notch 316 further ensures the relative positional accuracy of the flameout contact seat 34 and the flameout mounting base 31 in the circumferential direction, so that the electrical contact between the rotor 33 and the flameout contact seat 34 remains stable and reliable. This improves the overall structural rigidity and operational consistency of the flameout switch 3 and extends its service life.

[0032] Rotor 33 has a moving contact 331, and a receiving cavity 332. The moving contact 331 covers one end of the receiving cavity 332, and an elastic stop member 333 passes through the other end of the receiving cavity 332. A stop spring is provided between the elastic stop member 333 and the moving contact 331. The flameout mounting base 31 has several stop grooves 317. Rotation of rotor 33 causes the stop member 333 to disengage from or slide into the stop groove 317. Flameout contact plate seat 34 has a first stationary contact 343, a second stationary contact 344, and a moving contact 331. 1. It can contact the first stationary contact 343 and the second stationary contact 344 to realize the locomotive shutdown. The second stationary contact 344 has a first contact plate 3441 and a second contact plate 3442 extending to both sides at the end. The first contact plate 3441, the second contact plate 3442, and the second stationary contact 344 are Y-shaped. The rotation of the rotor 33 causes the moving contact 331 to rotate around the central axis of the rotor 33, causing the moving contact 331 to connect or disconnect the first stationary contact 343 from the first contact plate 3441 and the first stationary contact 343 from the second contact plate 3442. When the rotor 33 is in the initial position, the moving contact 331 is only in contact with the first stationary contact 343. When the rotor 33 is rotating, the elastic stop member 333 slides out of the first stop slot 317. When the stop member 333 slides into the next stop slot 317, one end of the moving contact 331 is in contact with the first stationary contact 343, and the other end is in contact with the first contact plate 3441 or the second contact plate 3442, thereby controlling the locomotive to shut down. The stop member 333 and the stop slot 317 provide clear positioning feedback, effectively preventing the switch from drifting or malfunctioning due to vibration. In addition, the Y-shaped second stationary contact 344 allows the rotor 33 to rotate to both sides, improving the anti-interference capability and action consistency of the shutdown switch 3 under complex working conditions.

[0033] The rotor 33 also includes a square rotating column 334, the rotating handle 32 has a square locking hole 321, the square rotating column 334 passes through the square locking hole 321, the side wall of the square locking hole 321 has a number of limiting locking grooves 322, the outer circumference of the square rotating column 334 has a number of limiting buckles 335, the limiting buckles 335 pass through the limiting locking grooves 322, and the middle of the square rotating column 334 has a deformation hole 336. The cooperation between the square rotating column 334 and the square locking hole 321 ensures the accuracy and synchronization of torque transmission between the rotating handle 32 and the rotor 33. The cooperation between the limiting buckle 335 and the limiting slot 322 effectively prevents the axial movement and circumferential free travel of the rotating handle 32 on the rotor 33, improving the operating feel and control precision. At the same time, the deformation hole 336 in the middle of the square rotating column 334 gives it a certain elastic deformation capability during assembly. This facilitates the smooth insertion of the limiting buckle 335 into the limiting slot 322 for quick assembly, and also allows it to maintain a tight fit with the rotating handle 32 after assembly through elastic restoring force. This enhances the stability and durability of the connection structure between the rotor 33 and the rotating handle 32, and reduces the risk of loosening due to vibration during long-term use.

[0034] The handle 32 is provided with a quenching end cap 35 at one end relative to the rotor 33. The quenching end cap 35 is detachably connected to the handle 32. The housing 1 has a supporting protrusion 18 extending outward from the circumference of the quenching through hole 14. The supporting protrusion 18 has a rotating groove 181. The driving block of the quenching end cap 35 passes through the rotating groove 181. The quenching end cap 35 is provided with several connecting buckles 351. The handle 32 has several connecting slots 323. The connecting buckles 351 pass through the connecting slots 323 to realize the detachable connection between the quenching end cap 35 and the handle 32. The side of the handle 32 is provided with a positioning groove 324. The side of the quenching end cap 35 is provided with a positioning protrusion 352. The positioning protrusion 352 can pass through the positioning groove 324. The flameout end cover 35 achieves quick assembly and disassembly with the handle 32 through the cooperation of the connecting buckle 351 and the connecting groove 323, which facilitates the maintenance and replacement of internal components. The positioning protrusion 352 and the positioning groove 324 ensure the precise positioning of the flameout end cover 35 on the handle 32, effectively preventing relative rotation. The rotation groove 181 on the supporting protrusion 18 provides a stable rotation track for the drive block of the flameout end cover 35, so that the handle 32 can rotate smoothly during operation. At the same time, the tight fit between the flameout end cover 35 and the supporting protrusion 18 forms an effective dynamic seal, preventing external contaminants and liquids from entering the switch, which significantly improves the protection level and service life of the flameout switch 3 in complex environments.

[0035] like Figure 1 , Figure 8 As shown, the inner cavity of the lower housing 17 is covered by a cover plate 5. Several second mounting posts 172 are provided inside the lower housing 17. The cover plate 5 has second mounting ears 51. The second mounting ears 51 and the second mounting posts 172 are detachably connected to the lower housing 17 by mounting bolts. A limiting protrusion 52 extends outward from the side of the cover plate 5 near the wire hole 111. The limiting protrusion 52 passes through the wire hole 111. The cover plate 5 achieves a stable connection with the lower housing 17 through the cooperation of the second mounting ears 51 and the second mounting posts 172, which effectively improves the protection performance of the internal components. At the same time, the limiting protrusion 52 and the wire hole 111 not only provide a precise positioning reference for the cover plate 5 to prevent it from shifting in a vibration environment, but also significantly reduce the assembly gap at the wire hole 111, enhance the overall sealing of this part, and create a more reliable protective environment for the cable laying and fixing.

[0036] The limiting protrusion 52 has a first locking tooth 53 on the side facing the lower housing 17, and a second locking tooth 112 is provided at the bottom of the wire hole 111. The first locking tooth 53 and the second locking tooth 112 can make the wire harness in the wire hole 111 more concentrated. While limiting the electrical connection wire, the first locking tooth 53 and the second locking tooth 112 can also pass the electrical connection wire into the groove of the first locking tooth 53 and the second locking tooth 112, making the wire harness neater. It also blocks the wire hole 111 to prevent external contaminants from entering the lower housing 17 through the wire hole 111 and affecting the toggle switch 4 and the start switch 2, thereby improving the stability of the functions of each switch in the locomotive switch assembly.

[0037] It should be noted that, as Figure 9 , Figure 10 As shown, the start switch 2 and the toggle switch 4 are existing technologies and will not be described in detail in this embodiment.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
