Description

Technical Field

[0001] The utility model relates to the technical field of side support switches for electric vehicles, in particular to a travel switch type waterproof side support switch for electric vehicles. Background Art

[0002] An electric bike's side stand switch is a critical safety component, ensuring the bike's stability and safety. In daily use, the raising and lowering of the side stands is directly linked to the vehicle's safety. When the side stands are lowered, they firmly support the vehicle, preventing it from accidentally tipping over. At this point, the side stand switch sends a signal to the bike's control system, restricting its operation and preventing the vehicle from accidentally starting or moving, effectively preventing it from rolling. When the side stands are retracted and ready for riding, the switch releases the restrictions on the electronic control system, allowing the vehicle to travel normally.

[0003] However, the side stand switches under the existing technology are often unable to withstand the test of harsh outdoor environments. For example, in areas with strong winds or frequent rainy seasons, the intrusion of sand, dust, mud and water will quickly corrode the inside of the side stand switch, making it lacking in reliability, sensitivity and durability, and prone to misjudgment or failure, posing a safety hazard to riding.

[0004] Therefore, it is socially desirable to develop a travel switch type waterproof side support switch for electric vehicles. Utility Model Content

[0005] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a travel switch type waterproof side support switch for electric vehicles, thereby ensuring a firm connection between the switch and the side support and electrical system of the electric vehicle, and stable and reliable signal transmission, so that the switch can work stably for a long time under various harsh riding conditions.

[0006] The technical solution adopted by the present invention is as follows: a travel switch type waterproof side support switch for an electric vehicle, comprising a side support switch body, wherein the side support switch body is mounted on the center of the rotating shaft of the side support at the bottom end of the electric vehicle frame; the structure of the side support switch body is as follows: comprising a protective shell, a positioning cam is arranged in the protective shell, a switch top rod is arranged in the rotation direction of the positioning cam, the head end of the switch top rod senses the rotation angle of the positioning cam, and the tail end is connected to a buffer spring, the other end of the buffer spring is connected to the travel switch, and the travel switch is electrically connected to the electric control system of the electric vehicle through a connecting wire.

[0007] As a further improvement of the above technical solution:

[0008] Preferably, the temple switch body includes at least a temple down state and a temple retracted state:

[0009] When the side stand is lowered, the positioning cam rotates and uses the raised part to abut against the switch push rod. The switch push rod is subjected to force to compress the buffer spring and transmit the force to the limit switch. The limit switch is turned on and sends an emergency shutdown signal to the electric control system of the electric vehicle through the connecting wire;

[0010] When the side support is retracted, the positioning cam is reset, the raised part of the positioning cam rotates away from the switch push rod, and the buffer spring releases the thrust to restore the travel switch to its initial state.

[0011] More preferably, the travel switch is an overload switch structure.

[0012] Preferably, a first sealing ring is installed at the lower end of the cavity of the protective shell, and the first sealing ring is used to stop the bottom water of the positioning cam;

[0013] More preferably, the first sealing ring is an O-ring structure.

[0014] Preferably, a second sealing ring is installed at the upper end of the cavity of the protective shell, and the second sealing ring is used to stop the water at the top of the positioning cam;

[0015] More preferably, the second sealing ring is an O-ring structure.

[0016] Preferably, an inner cavity is formed between the upper cover and the lower cover of the side support switch body, and a sealing colloid is provided in the inner cavity, and the sealing colloid is used to completely wrap the connecting wires and the welding points;

[0018] The beneficial effects of the utility model are as follows:

[0019] The utility model has a compact structure and senses the position of the side support switch push rod through the structural principle of a cam. The push rod and spring are used as the force transmission structure of the switch, and the overload plate switch is used as the travel switch mechanism of the side support switch. The utility model adopts an electric vehicle travel switch type waterproof side support switch to improve the waterproof performance and durability of the side support switch. It has the advantages of easy assembly and low cost, improves product performance, and reduces the user's subsequent maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of the present invention.

[0030] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0031] like Figures 1 to 3, shows a schematic diagram of the structural state of a travel switch type waterproof side support switch for an electric vehicle in one embodiment of the present invention; for the convenience of description, the accompanying drawings only show the structure related to the embodiment of the present invention.

[0032] The travel switch type waterproof side support switch for electric vehicles of this embodiment includes a side support switch body 1, which is installed on the center of the rotating shaft of the side support at the bottom end of the electric vehicle frame to facilitate accurate sensing of the position status of the side support; the structure of the side support switch body 1 is: it includes a protective shell 101, a positioning cam 102 is arranged in the protective shell 101, and a switch top rod 103 is arranged in the rotation direction of the positioning cam 102. The head end of the switch top rod 103 senses the rotation angle of the positioning cam 102, and the tail end is connected to the buffer spring 104. The other end of the buffer spring 104 is connected to the travel switch 105, and the travel switch 105 is electrically connected to the electric control system of the electric vehicle through the connecting wire 106.

[0033] In this embodiment, the temple switch body 1 can be operated in two states: a temple down state and a temple up state.

[0034] When the temple is lowered, the positioning cam 102 rotates and uses the raised portion to abut against the switch push rod 103. The switch push rod 103 is subjected to force to compress the buffer spring 104 and transmit the force to the limit switch 105. The limit switch 105 is turned on and sends an emergency shutdown signal to the electric control system of the electric vehicle through the connecting wire 106.

[0035] When the side support is retracted, the positioning cam 102 is reset, the raised portion of the positioning cam 102 rotates away from the switch push rod 103, and the buffer spring 104 releases the thrust to restore the travel switch 105 to its initial state.

[0036] In this embodiment, for example, the switch top rod 103 is made of wear-resistant engineering plastic, one end of which senses the rotation angle of the positioning cam 102, and the other end is connected to the buffer spring 104; the buffer spring 104 is used to filter the impact force and transmit the thrust applied to the limit switch 105. When the side support is retracted, the buffer spring 104 releases the thrust to restore the limit switch 105 to its initial state.

[0037] In this embodiment, for example, the travel switch 105 uses an overload switch that is fatigue-resistant and highly sensitive to ensure accurate detection of the temple state and to work normally in various harsh environments.

[0038] In this embodiment, illustratively, the connecting wire 106 uses a wire material with good insulation performance and wear resistance to ensure the stability and reliability of signal transmission.

[0039] In this embodiment, a first sealing ring 2 is installed at the lower end of the cavity of the protective housing 101. The first sealing ring 2 is used to stop the bottom of the positioning cam 102 from leaking.

[0040] Furthermore, the first sealing ring 2 is an O-ring structure.

[0041] In this embodiment, a second sealing ring 3 is installed at the upper end of the cavity of the protective housing 101, and the second sealing ring 3 is used to stop the top of the positioning cam 102;

[0042] Furthermore, the second sealing ring 3 is an O-ring structure.

[0043] In this embodiment, an inner cavity 4 is formed between the upper cover and the lower cover of the side support switch body 1. A sealing colloid 5 is provided in the inner cavity 4. The sealing colloid 5 is used to completely encapsulate the connecting wire 106 and the welding point.

[0044] Furthermore, the sealing colloid 5 is filled into the inner cavity 4 by potting to prevent the intrusion of impurities and protect the normal operation of the switch.

[0045] The result of the present invention is reasonable. The position of the switch top rod 103 in the side support switch is sensed by the structural principle of the positioning cam 102. The switch top rod 103 and the buffer spring 104 are used as the force conduction structure of the switch. The side support switch 105 adopts an overload plate switch. The overall structure improves the waterproof performance and durability of the side support switch, and has the advantages of easy assembly and low cost.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely represent implementation methods of the present invention. 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 a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
