Description

Technical Field

[0001] This application relates to the field of vehicle accessory technologies, and particularly to an electric vehicle side stand switch with high safety. Background Art

[0002] The side stand switch for electric vehicles is often installed on the single stand of the electric vehicle. When the single stand is lowered to the ground, the side stand switch is activated, causing the moving contact piece inside the side stand switch to disconnect from the two originally connected static contact pieces, disconnecting the motor circuit, and the electric vehicle cannot be started. If the single stand is not lifted, the circuit cannot be connected, and even if the key is turned on, the vehicle cannot be started, avoiding safety accidents caused by the vehicle moving by itself due to motor or circuit failures when the vehicle is parked temporarily, and at the same time reducing the potential safety hazards caused by driving the vehicle without lifting the single stand due to negligence.

[0003] The common side stand switch for electric vehicles includes a housing with a receiving cavity. A switch rotor is arranged in the receiving cavity. The switch rotor includes an annular moving contact piece and a rotor body made of copper material. When the side stand rotates, the rotor body and the moving contact piece are linked by rotation, so that the moving contact piece and the static contact piece are conductively connected. Since the entire rotor body and the moving contact piece are made of copper material, when the rotor body and the moving contact piece are in direct contact, the rotor body will be charged, and thus the single stand on the electric vehicle will also be charged, posing a safety hazard, so it needs to be improved. Utility Model Content

[0004] In order to reduce the safety hazards caused by the charged single stand of the electric vehicle, this application provides an electric vehicle side stand switch with high safety.

[0005] An electric vehicle side stand switch with high safety provided by this application adopts the following technical solutions:

[0006] An electric vehicle side stand switch with high safety includes a base and a switch rotor rotatably arranged on the base, and also includes a micro switch arranged on the base. A cam is arranged on the switch rotor. When the cam rotates close to the micro switch, the cam presses the micro switch.

[0007] By adopting the above technical solutions, the switch rotor rotates on the base. The switch rotor abuts against the micro switch through the cam, and the cam presses the micro switch, closing the circuit, so that the side stand is in the retracted state. When the electric vehicle handle is rotated, the vehicle moves forward; when the cam rotates away from the micro switch, the circuit is disconnected, the side stand supports the ground, and the vehicle does not move when the handle is rotated. The side stand switch is opened or closed by the cam pressing or moving away from the micro switch, and there is no situation where the copper sheet contacts the electric vehicle side stand, so that the electric vehicle single stand is not easily charged, reducing the safety hazards caused by the charged single stand.

[0008] Optionally, a compression spring is provided on the micro switch, the direction of the elastic force of the compression spring is parallel to the pressing direction of the micro switch, one end of the compression spring is provided at the end of the micro switch, and a top block is provided at the end of the compression spring away from the micro switch. When the cam rotates close to the top block, the cam abuts against the top block, and the top block drives the compression spring to press the micro switch.

[0009] By adopting the above technical solution, the micro switch is driven to be pressed or reset through the compression spring and the top block, thereby avoiding direct contact between the micro switch and the cam and reducing the wear of the press switch. At the same time, the spring buffers the pressure of the top block on the micro switch, making the micro switch less likely to be damaged and increasing the service life of the micro switch.

[0010] Optionally, a accommodating cavity is provided on the base, the switch rotor is rotatably arranged in the accommodating cavity, a switch cavity is provided on the base, the micro switch is arranged in the switch cavity, a driving groove is provided on the base, and the opposite side walls of the driving groove connect the accommodating cavity and the switch cavity, the compression spring and the top block are slidably arranged in the driving groove, and the compression spring drives the top block to protrude from the driving groove into the accommodating cavity.

[0011] By adopting the above technical solution, the accommodating cavity facilitates the positioning and installation of the base and the switch rotor, the switch cavity makes it convenient to fix the micro switch in the cavity, and the driving groove facilitates the positioning and installation of the top block, making it easy to assemble the side support switch.

[0012] Optionally, a limit block is provided at one end of the top block close to the micro switch, the limit block is slidably arranged in the driving groove, the outer diameter of the limit block is larger than the inner diameter of the connecting port between the driving groove and the accommodating cavity, and the compression spring is arranged at one end of the limit block close to the micro switch.

[0013] By adopting the above technical solution, the outer diameter is larger than the connecting port of the driving groove and the accommodating cavity, the limit block prevents the top block from leaving the driving groove, and the limit block is slidably arranged in the driving groove, so that the sliding of the top block is stable.

[0014] Optionally, the end of the top block for abutting against the cam is an arc surface, and the cam is provided with an arc surface for abutting against the top block.

[0015] By adopting the above technical solution, the arrangement of the arc surface and the arc surface enables the cam to abut against the top block more smoothly.

[0016] Optionally, a shell is provided on the base, and the shell is used to close the switch cavity and the driving slot.

[0017] By adopting the above technical solution, the housing seals the switch cavity and the drive groove, preventing impurities from entering the switch cavity and the drive cavity to affect the pressing of the micro switch or the sliding of the top block.

[0018] Optionally, two waterproof washers are sleeved on the switch rotor, the connection port between the driving groove and the accommodating cavity is located between the two waterproof washers, and the two waterproof washers seal the connection port between the driving groove and the accommodating cavity.

[0019] By adopting the above technical solution, the waterproof washer effectively prevents water from flowing into the switch cavity and the driving groove along the rotation gap between the base and the switch rotor.

[0020] Optionally, a dial block is arranged on the switch rotor.

[0021] By adopting the above technical solution, the dial block facilitates the connection with the components on the electric vehicle, making it convenient for the switch rotor to rotate.

[0022] Optionally, a connecting cylinder is coaxially arranged on the switch rotor, a connecting hole for inserting the connecting cylinder is formed on the base, several elastic convex strips are arranged on the inner wall of the connecting cylinder, and a countersunk head sleeve block is further included.

[0023] By adopting the above technical solution, the countersunk head sleeve block is inserted into the connecting cylinder, so that the base and the switch rotor are rotationally connected. When the countersunk head sleeve block is inserted into the connecting cylinder, the elastic convex strips are deformed, and the elastic convex strips abut against the outer wall of the countersunk head sleeve block, so that the fixed base and the switch rotor will not be separated.

[0024] Optionally, a stable groove for accommodating the end part of the compression spring is formed on the limiting block.

[0025] By adopting the above technical solution, the spring is conveniently installed and the elastic force direction is stable, so that the sliding direction of the top block is stable.

[0035] The following further describes the present application in detail with reference to the accompanying drawings and embodiments.

[0036] An embodiment of the present application discloses a high-security side stand switch for an electric vehicle. Referring to Figure 1 , Figure 2 , Figure 3 , the high-security side stand switch for an electric vehicle includes a base 1 and a switch rotor 2 rotatably arranged on the base 1. An accommodating cavity 41 is formed on the base 1, and the switch rotor 2 is rotatably arranged in the accommodating cavity 41. A connecting cylinder 24 is coaxially fixed on the switch rotor 2. The switch rotor 2 and the connecting cylinder 24 are integrally injection-molded. A connecting hole 12 for inserting the connecting cylinder 24 is formed on the base 1. A plurality of elastic convex strips 25 are arranged on the inner wall of the connecting cylinder 24. The high-security side stand switch for an electric vehicle further includes a countersunk head sleeve block 5. The countersunk head sleeve block 5 is inserted into the connecting cylinder 24, and the elastic convex strips 25 abut against the outer wall of the countersunk head sleeve block 5, so that the switch rotor 2 and the base 1 are stably connected. The countersunk head sleeve block 5 is hollow. After a bolt is inserted into the inner cavity of the countersunk head sleeve block 5, it is fixed by a nut, so that the base 1 and the switch rotor 2 are firmly connected.

[0037] Referring to Figure 3 , Figure 4 , the high-security side stand switch for an electric vehicle further includes a micro switch 3. A switch cavity 42 is formed on the base 1. The switch cavity 42 facilitates the positioning and clamping of the micro switch 3 in the switch cavity 42. A cam 21 is fixed on the switch rotor 2. The cam 21 and the switch rotor 2 are integrally injection-molded. When the cam 21 rotates to be close to the micro switch 3, the cam 21 presses the micro switch 3.

[0038] Referring to Figure 3 , Figure 4The end of the micro switch 3 is butted against a compression spring 31, and the elastic force direction of the compression spring 31 is parallel to the pressing direction of the micro switch 3. One end of the compression spring 31 is butted against the end of the micro switch 3, and a top block 32 is arranged at the end of the compression spring 31 away from the micro switch 3. A driving groove 43 is provided on the base 1, and the two opposite side walls of the driving groove 43 connect the accommodating chamber 41 and the switch chamber 42. The compression spring 31 is located in the driving groove 43, and the top block 32 is slidably connected in the driving groove 43. The compression spring 31 drives the top block 32 to protrude from the driving groove 43 to the accommodating chamber 41, so that the cam 21 presses the top block 32 after the switch rotor 2 rotates. The top block 32 presses on the compression spring 31, so that the compression spring 31 presses the micro switch 3.

[0039] Reference Figure 2 , Figure 3 , Figure 4 The end of the top block 32 close to the micro switch 3 is fixed with a limit block 33, which is slidably connected in the driving groove 43. The outer diameter of the limit block 33 is larger than the inner diameter of the connection port between the driving groove 43 and the accommodating chamber 41, so that the top block 32 is not easy to be separated from the driving groove 43. The compression spring 31 abuts against the end of the limit block 33 close to the micro switch 3. The limit block 33 is provided with a stabilizing groove 45 for accommodating the end of the compression spring 31. The compression spring 31 abuts against the bottom of the stabilizing groove 45, so that the elastic force direction of the compression spring 31 is stable, and the installation of the compression spring 31 is also convenient.

[0040] Reference Figure 4 The end of the top block 32 for abutting the cam 21 is an arc surface 34, and the cam 21 is fixed with an arc surface 22 for abutting the top block 32. The top block 32 drives the compression spring 31 to press the micro switch 3, so that the cam 21 presses the top block 32 smoothly.

[0041] Reference Figure 1 , Figure 2 , Figure 3 The base 1 is fixed with a housing 11, and the housing 11 and the base 1 are fused into one body by ultrasonic plastic welding, and the housing 11 is used to seal the switch cavity 42 and the drive slot 43. Two waterproof washers 44 are sleeved on the switch rotor 2, and the waterproof washers 44 and the connecting tube 24 are coaxially arranged. The connection between the drive slot 43 and the accommodating cavity 41 is located between the two waterproof washers 44. The two waterproof washers 44 seal the connection between the drive slot 43 and the accommodating cavity 41, so that the drive slot 43 is not easily immersed in water, and thus the micro switch 3 is not easily damaged by immersion in water. A shift block 23 is fixed on the side of the switch rotor 2 away from the accommodating cavity 41, and the shift block 23 is convenient for connecting other parts of the electric vehicle, thereby facilitating the rotation of the switch rotor 2.

[0042] The implementation principle of a high - security side stand switch for an electric vehicle in an embodiment of this application is as follows: When a rider opens the side stand, the cam 21 rotates away from the top block 32, the circuit is disconnected, and turning the handlebar does not move the vehicle. When the rider retracts the side stand and is ready to ride, the switch rotor 2 rotates, the cam 21 presses the top block 32, driving the compression spring 31 to press the micro - switch 3, and the circuit is closed, so the electric vehicle can ride. By pressing or resetting the micro - switch 3, the side stand switch can be in an open or closed state. There is no situation where a copper sheet contacts the side stand of the electric vehicle, so it is not easy for the single stand of the electric vehicle to be electrified, reducing the safety hazard caused by the electrified single stand.

[0043] The above are all preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
