Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motorcycle safety technology, specifically a motorcycle side stand kill switch. Background Technology
[0002] The side stand kill switch is usually installed on the side stand (also known as the stand) of a motorcycle. When the side stand is lowered to support the motorcycle, the switch is automatically triggered, causing the engine to shut off and preventing the motorcycle from starting.
[0003] Currently, the traditional motorcycle side stand engine stop switch works by retracting the side stand, which contacts the push rod and pushes the moving contact to contact the stationary contact, thus completing the circuit and allowing the motorcycle to start. When the side stand supports the motorcycle, it moves away from the push rod, and the return spring pushes the moving contact and push rod back to their original positions, thus automatically stopping the engine.
[0004] However, while the moving contact plays a crucial role in the circuit, it relies solely on a spring to maintain its position and provide the necessary contact pressure during operation. Over time, especially with frequent use of motorcycles and exposure to various road conditions and vibrations, the spring may gradually lose its original elasticity and strength. Spring fatigue not only weakens the contact pressure between the moving and stationary contacts but may also cause the moving contact to easily deviate from its intended position under vibration conditions, resulting in intermittent circuit disconnection and reduced driving safety. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides a side stand ignition switch for motorcycles.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle side stand kill switch, comprising a housing, a slider disposed inside the housing, a push rod disposed inside the slider, a stationary contact disposed inside the housing, a contact spring disposed inside the slider, and a moving contact disposed at one end of the contact spring;
[0007] A fixing mechanism is provided inside the slider. The fixing mechanism includes four springs, which are fixedly connected to the inside of the slider. The springs are arranged in pairs. Four connecting blocks are fixedly installed on one end of each of the four springs, and two connecting blocks are arranged in pairs. A fixing block is fixedly installed on the opposite side of each pair of connecting blocks. A fixing plate is fixedly installed on the bottom end of each fixing block. Connecting plates located at the bottom end of the fixing plate are fixedly installed on both ends of the moving contact. An insert block is provided inside the housing.
[0008] Preferably, a return spring is provided inside the housing, and one end of the return spring is fixedly connected to the slider.
[0009] Preferably, the housing is provided with a pressure block located on the surface of the push rod, and both the housing and the pressure block are provided with an outer sealing ring and an inner sealing ring located on the surface of the push rod.
[0010] Preferably, a wire bonding plate is provided at the bottom of the interior of the housing.
[0011] Preferably, a pressure plate is provided at the bottom end of the wire bonding board, and screws are provided inside the wire bonding board and the pressure plate.
[0012] Preferably, the number of screws is four, and the screws are arranged in an array.
[0013] Preferably, the side of the insert block and the fixing block opposite each other are designed with bevels, and the bevels are parallel to each other.
[0014] Preferably, the slider has two square holes on one side, and the two square holes are parallel to each other.
[0015] Preferably, both the fixing block and the fixing plate are longitudinally symmetrical about the center of the moving contact, and the bottom end of the fixing plate is roughened.
[0016] Preferably, the spring is designed to be longitudinally symmetrical at the center of the fixed block.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention allows the insert block to enter the interior of the slider and compress the fixed block and fixed plate to move. When the fixed block moves, it drives the connecting block to move, and the spring is stretched. At this time, the fixed plate contacts the top of the connecting plate, thereby fixing the connecting plate and the moving contact. Finally, by driving the insert block to enter the interior of the slider and compressing the fixed plate to fix the connecting plate and the moving contact, the stability is increased, preventing the moving contact from detaching from the surface of the stationary contact during vehicle operation, which could cause the vehicle to stall and thus increasing driving safety.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] like Figures 1 to 7 As shown, this utility model provides a side stand kill switch for motorcycles, including a housing 1, a slider 3 inside the housing 1, a push rod 4 inside the slider 3, a stationary contact 5 inside the housing 1, a contact spring 6 inside the slider 3, and a moving contact 7 at one end of the contact spring 6.
[0030] The fixing mechanism is located inside the slider 3. The fixing mechanism includes four springs 9, which are fixedly connected inside the slider 3. The springs 9 are arranged in pairs. Four connecting blocks 10 are fixedly installed on one end of each of the four springs 9. The connecting blocks 10 are arranged in pairs. A fixing block 11 is fixedly installed on the opposite side of each pair of connecting blocks 10. A fixing plate 12 is fixedly installed on the bottom end of the fixing block 11. A connecting plate 13 located at the bottom end of the fixing plate 12 is fixedly installed on both ends of the moving contact 7. An insert block 8 is provided inside the housing 1.
[0031] Using the above scheme: When the operator retracts the side stand, the surface of the side stand will contact the surface of the push rod 4, and will push the push rod 4 to move. The push rod 4 will push the slider 3 to move. When the slider 3 moves, the slider 3 will drive the contact spring 6 and the moving contact 7 to move. Then the surface of the moving contact 7 will contact the surface of the stationary contact 5. When they contact, the contact spring 6 will be compressed, which can fix the moving contact 7. At the same time, the circuit is turned on, and then the motorcycle can be started.
[0032] At the same time, the insert 8 will enter the interior of the slider 3, and then the insert 8 will contact the surface of the fixed block 11 and squeeze the fixed block 11 to move. The fixed block 11 will drive the connecting block 10 to move. When the connecting block 10 moves, the spring 9 will be stretched. Then the fixed block 11 will drive the fixed plate 12 to descend and contact the top of the connecting plate 13. The fixed plate 12 can then fix the connecting plate 13 and the moving contact 7. Finally, by driving the insert 8 to enter the interior of the slider 3 and squeezing the fixed plate 12 to fix the connecting plate 13 and the moving contact 7, the stability is increased, and the moving contact 7 is prevented from detaching from the surface of the stationary contact 5 during vehicle operation, which would cause the vehicle to stall, thus increasing the safety of driving.
[0033] like Figure 4 , Figure 5 and Figure 7 As shown, the side opposite to the insertion block 8 and the fixing block 11 is designed with a bevel, and the bevels are parallel to each other. The slider 3 has two square holes on one side, and the two square holes are parallel to each other.
[0034] The above solution is adopted: through the design of the insert block 8 and the fixing block 11, since the opposite side of the insert block 8 and the fixing block 11 are both designed with bevels and are parallel to each other, the resistance caused by squeezing will be reduced when the insert block 8 and the fixing block 11 come into contact. Through the design of the slider 3, since a square hole is opened on one side of the slider 3, the insert block 8 will enter the interior of the slider 3 along the square hole, and the size of the insert block 8 is adapted to the square hole, so the insert block 8 will not interfere with the movement of the slider 3.
[0035] like Figure 5 and Figure 6 As shown, both the fixing block 11 and the fixing plate 12 are longitudinally symmetrical about the center of the moving contact 7. The bottom end of the fixing plate 12 is rough. The spring 9 is longitudinally symmetrical about the center of the fixing block 11.
[0036] The above solution is adopted: through the design of the fixing block 11 and the fixing plate 12, since the fixing plate 12 is symmetrical and the bottom is rough, the fixing effect on the moving contact 7 can be increased. Through the design of the spring 9, since the spring 9 is symmetrical, when the insert 8 moves away from the fixing block 11, the two stretched springs 9 will pull the fixing block 11 and the fixing plate 12 to reset at the same time, thereby improving the stability of its movement.
[0037] Example 2
[0038] like Figure 3 As shown, a return spring 2 is installed inside the housing 1, and one end of the return spring 2 is fixedly connected to the slider 3.
[0039] The above solution is adopted: through the design of the return spring 2, when the side support pushes the push rod 4 and the slider 3 to move, it will compress the return spring 2. When the side support moves away from the surface of the push rod 4, the compressed return spring 2 will push the slider 3 and the push rod 4 to reset, and the moving contact 7 will move away from the surface of the stationary contact 5, thereby automatically shutting off the motorcycle engine.
[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the housing 1 has a pressure block 14 located on the surface of the push rod 4 inside. Both the housing 1 and the pressure block 14 have an outer sealing ring 15 and an inner sealing ring 16 located on the surface of the push rod 4 inside. The bottom of the housing 1 has a welding plate 17.
[0041] The above solution is adopted: through the design of pressure block 14, outer sealing ring 15 and inner sealing ring 16, since the outer sealing ring 15 and inner sealing ring 16 are both set on the surface of push rod 4, water, dust and other substances can be prevented from entering the flameout switch. Through the design of wire bonding board 17, the circuit required by the switch can be installed on the surface of wire bonding board 17, and then epoxy resin can be potted on it to prevent water from entering the switch from the bottom side, thus ensuring the overall waterproof performance of the flameout switch.
[0042] like Figure 2 and Figure 3 As shown, a pressure plate 19 is provided at the bottom of the wire bonding board 17, and screws 18 are provided inside the wire bonding board 17 and the pressure plate 19. There are four screws 18, and the screws 18 are arranged in an array.
[0043] The above solution is adopted: through the design of screw 18 and pressure plate 19, screw 18 can be inserted into the inside of wire bonding board 17 and pressure plate 19, thereby fixing them to the housing 1. Screw 18 can fix and protect the wire bonding. Through the design of screw 18, since there are four screws 18, the fixing effect of wire bonding board 17 and pressure plate 19 can be increased.
[0044] Working principle and usage process of this utility model:
[0045] First, when the operator retracts the side stand, the surface of the side stand will contact the surface of the push rod 4, pushing the push rod 4 and the slider 3 to move. When the slider 3 moves, the return spring 2 will be compressed, and then the surface of the moving contact 7 will contact the surface of the stationary contact 5. At the same time, the circuit is connected, and the motorcycle can be started. Simultaneously, the insert block 8 will also enter the interior of the slider 3, and will squeeze the fixed block 11 and the fixed plate 12 to move. When the fixed block 11 moves, it will drive the connecting block 10 to move, and the spring 9 will be stretched. At this time, the fixed plate 12 will contact the top of the connecting plate 13, thereby fixing the connecting plate 13 and the moving contact 7, increasing its driving safety. When the side stand moves away from the surface of the push rod 4, the compressed return spring 2 will push the slider 3, the contact spring 6 and the moving contact 7 to reset, and the moving contact 7 will move away from the surface of the stationary contact 5, and the motorcycle engine will automatically shut off, thus completing the operation process.
