Electric scooter with steering control of turn signals by steering rod

Abstract

This invention discloses an electric scooter with turn signals controlled by a steering lever. The footrest has a mounting section at its front end, and a bogie passes through and is rotatably connected to the mounting section. The mounting section contains two symmetrical sensors, one on the left and one on the right. These sensors are connected to a controller, which in turn connects to the front and rear turn signals. The bogie has a magnetic sensing block. When the bogie rotates to the left, the left sensor detects the magnetic block and, through the controller, activates the two left turn signals. When the bogie rotates to the right, the right sensor detects the magnetic block and, through the controller, activates the two right turn signals. The two sensors are arranged in a V-shape. In this electric scooter, when turning, the rotation of the bogie causes different sensors to send feedback signals to the controller via the magnetic sensing block, automatically activating the corresponding turn signals. Furthermore, an accelerator pedal and a brake pedal can be installed in the footrest to achieve full foot control and a wireless bogie. A floating, sealed structure is also provided in the footrest to protect the controller.

Description

Technical Field

[0001] This invention relates to the field of scooter components, and more particularly to an electric scooter with turn signals controlled by a steering lever. Background Technology

[0002] Electric scooters are transportation tools based on traditional human-powered skateboards, with the addition of electric components. As urban roads and transportation have developed and improved, more and more people are pursuing convenient travel methods, and electric scooters have emerged as a mainstream choice for short-distance urban transportation.

[0003] Currently, most electric scooters have the turn signal control unit located on the handlebars of the bogie. However, this structure requires wiring on the bogie, affecting its installation, removal, and folding. Additionally, electric scooters require a power supply and controller in the footboard area, typically installed there. Since the controller and power supply are prone to short circuits when exposed to rain, a waterproof structure is needed at the footboard location to protect them. The current method involves creating a cavity and mounting steps at the footboard, with a sealing ring between the cover and the mounting steps. When the cover is tightly closed, the sealing ring is compressed, creating a seal. However, this waterproof structure is a ring-shaped structure, relying on compression for sealing. Its sealing surface is relatively singular, and localized areas are prone to aging and leakage. When this occurs, the entire waterproof structure fails, ultimately causing the internal controller to become waterlogged and damaged. Summary of the Invention

[0004] In existing technologies, the turn signal control is located on the handle, resulting in wiring on the bogie, which affects the loading, unloading, and folding of the bogie. In addition, due to the presence of a controller and the use of a single sealing ring compression structure for waterproof protection, local water leakage is prone to occur, which can damage the internal controller. Therefore, this invention provides an electric scooter that controls the turn signal via a steering lever.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] This electric scooter, controlled by a steering lever, includes a footrest, a power supply located within the footrest, a controller located within the footrest and connected to the power supply, a bogie rotatably mounted on the footrest, a front wheel at the bottom of the bogie, and a rear wheel at the rear of the footrest. A mounting section is located at the front of the footrest, through which the bogie passes and rotatably connects. The mounting section contains two symmetrical sensors, one on the left and one on the right, connected to the controller. The controller is connected to the front and rear turn signals. The bogie has magnetic blocks. When the bogie rotates to the left, the right sensor detects the magnetic block and, through the controller, activates both left turn signals. When the bogie rotates to the right, the left sensor detects the magnetic block and, through the controller, activates both right turn signals. The two sensors are arranged in a V-shape. In this design, when the electric scooter turns, the rotating bogie causes different sensors to send feedback signals to the controller via magnetic blocks, thereby automatically turning on the corresponding turn signals. In addition, accelerator and brake pedals can be installed on the foot pedals to achieve full foot control and a wireless bogie.

[0007] Preferably, the sensor is a reed switch or a Hall sensor, and the mounting part is provided with two symmetrical sliding holes. The two sensors are slidably disposed in the sliding holes, and the sensing sensitivity is adjusted by adjusting the position of the sensors.

[0008] Preferably, the mounting section is provided with a cover plate, and the cover plate has a sliding groove that covers the mounting section and forms a sliding hole with the mounting section. The sliding hole formed by this structure is used to install the sensor.

[0009] The foot pedal section has a bottom shell and a cover plate that fits onto the bottom shell. A waterproof structure is provided between the bottom shell and the cover plate. The waterproof structure includes: an annular groove on the bottom shell; an annular outer frame located at the bottom of the cover plate and extending into the annular groove; an annular inner frame located at the bottom of the cover plate and extending into the bottom of the bottom shell; an outer sealing ring located in the annular groove and pressed against the annular outer frame; and an inner sealing ring located at the bottom of the annular inner frame and abutting against the bottom surface of the bottom shell. The sealed space enclosed by the annular inner frame and the bottom shell is used to install the controller. The inner sealing ring covers... It includes a vertical part and a horizontal part. The vertical part is attached to the side wall of the inner ring frame, and the horizontal part is attached to the bottom surface of the inner ring frame. The cross-section of the annular groove, the outer ring frame, and the inner ring frame is a square structure. There are four vertically sliding sliders in the annular groove, and each of the four inner side walls of the annular groove is provided with a sliding hole. Each sliding hole is provided with a horizontally sliding frame. The sliding frame extends into the annular groove and there is an inclined surface between it and the slider. The slider is pressed down by the outer ring frame and pushed by the inclined surface to slide the four sliding frames inward to press the vertical part of the inner sealing ring.

[0010] Preferably, the top of the slider is provided with an annular pressure plate, and the outer sealing ring presses against the top of the pressure plate. The pressure plate is used to contact the outer sealing ring to increase the uniformity of contact between the outer sealing ring and the outer sealing ring.

[0011] Preferably, the outer sealing ring has a U-shaped cross-section and is fitted onto the bottom of the annular outer frame.

[0012] Preferably, the junction of adjacent sliding frames is provided with mutually cooperating abutting inclined surfaces. When the sliding frame slides inward, the four sets of abutting inclined surfaces abut against each other and the four sliding frames form a ring structure to compress the inner sealing ring.

[0013] Preferably, the vertical portion of the inner sealing ring is arched in the middle to form an arched structure. The arched structure can deform under pressure to increase the contact area.

[0014] Preferably, the cover plate is a one-piece molded metal structure, with the inner and outer sealing rings respectively fitted onto the bottom of the inner and outer annular frames. The metal structure is used to conduct heat from the controller, accelerating heat dissipation.

[0015] Preferably, the bottom shell has a wire passage hole, and a flexible waterproof plug is provided at the wire passage hole. The waterproof plug is used to seal the wire passage.

[0016] Compared with the prior art, the advantages of this invention are as follows: This application controls the turn signal illumination by rotating the rotating frame, avoiding wiring on the bogie and facilitating the loading, unloading, and folding of the bogie. In addition, the internal controller is protected by a two-stage sealing structure. Even if a partial sealing structure fails, the double sealing structure can still provide a sealing effect, ensuring the airtightness and thus protecting the internal controller. Furthermore, when the cover is tightened, the slider is pressed down, and the sliding frame slides inward, squeezing the side wall of the inner sealing ring, so that the side wall and bottom wall of the inner sealing ring form a double seal. Combined with the outer sealing ring in the annular groove, a triple seal is formed, which greatly increases the sealing effect. Attached Figure Description

Detailed Implementation

[0029] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0031] This embodiment mainly describes the title of an electric scooter that controls the turn signals via a steering lever, as follows:

[0032] Electric scooters that control turn signals via a steering lever, such as Figure 1-4As shown, the device includes a foot pedal part 03, a power supply located within the foot pedal part 03, a controller located within the foot pedal part 03 and connected to the power supply, a bogie 01 rotatably mounted on the foot pedal part 03, a front wheel located at the bottom of the bogie 01, and a rear wheel located at the rear side of the foot pedal part 03. A mounting part 031 is located at the front end of the foot pedal part 03. The bogie 01 passes through and is rotatably connected to the mounting part 031. Two symmetrical sensors 022 are located within the mounting part 031. The sensors 022 are connected to the controller, which is connected to front and rear turn signals 04. A sensing magnetic block 021 is located on the bogie 01. When the bogie rotates to the left, the right sensor 022 senses the magnetic block 021 and controls the two front and rear left turn signals 04 to illuminate via the controller. When the bogie rotates to the right, the left sensor 022 senses the magnetic block 021 and controls the two front and rear right turn signals 04 to illuminate via the controller. Two sensors 022 are arranged in a V-shape. The bogie 01 includes a front wheel frame 012 and a stand with handles 011. The stand 011 has a mounting base at its bottom. The front wheel frame 012 has a rod that passes through the mounting part 031 and extends into the mounting base, where it is fixedly connected. A magnetic block 021 is mounted on the front wheel frame 012. In this design, when the electric scooter turns, rotating the bogie 01 causes different sensors 022 to send feedback signals to the controller via the sensing magnetic block 021, thereby controlling the corresponding turn signal 04 to turn on automatically. In addition, a speed control pedal 05 can be installed in the foot pedal part 03 to achieve full foot control and a wireless bogie 01.

[0033] Preferably, the sensor 022 is a reed switch or a Hall sensor, and the mounting part 031 is provided with two symmetrical sliding holes. The two sensors 022 are slidably disposed in the sliding holes, and the sensing sensitivity is adjusted by adjusting the position of the sensors 022.

[0034] Preferably, the mounting portion 031 is provided with a cover plate 023, which has a sliding groove that covers the mounting portion 031 and forms a sliding hole with the mounting portion 031. The sliding hole formed by this structure is used to install the sensor 022. The mounting portion 031 is provided with a mounting groove, in which both the cover plate 023 and the sensor 022 are disposed, and the mounting groove is provided with a cover 032 that covers its opening.

[0035] like Figure 5-10As shown, the foot pedal part 03 is provided with a bottom shell 10 and a cover plate 20 covering the bottom shell 10. A waterproof structure is provided between the bottom shell 10 and the cover plate 20. The waterproof structure includes: an annular groove 102, which is provided on the bottom shell 10; an annular outer frame 201, which is located at the bottom of the cover plate 20 and can extend into the annular groove 102; an annular inner frame 202, which is located at the bottom of the cover plate 20 and covers and extends into the inner bottom of the bottom shell 10; an outer sealing ring 40, which is provided in the annular groove 102 and is pressed by the annular outer frame 201; and an inner sealing ring 30, which is provided at the bottom of the annular inner frame 202 and can abut against the inner bottom surface of the bottom shell 10. The sealed space enclosed by the annular inner frame 202 and the bottom shell 10 is used to install the scooter controller. 30 includes a vertical part and a horizontal part. The vertical part is attached to the side wall of the inner ring 202, and the horizontal part is attached to the bottom surface of the inner ring 202. The cross-section of the annular groove 102, the outer ring 201, and the inner ring 202 is a square structure. The annular groove 102 is provided with four vertically sliding sliders 104, and each of the four inner side walls of the annular groove 102 is provided with a sliding hole 103. Each sliding hole 103 is provided with a horizontally sliding bracket 105.

The slider 104 is pressed down by the outer ring 201 and pushed by the inclined surface to push the four sliding brackets 105 inward to press the vertical part of the inner sealing ring 30. In this solution, dynamic sealing is achieved. When the cover plate 20 is tightened, the slider 104 is pressed down, and the sliding frame 105 slides inward to squeeze the side wall of the inner sealing ring 30, so that the side wall and bottom wall of the inner sealing ring 30 form a double seal. In addition, the outer sealing ring 40 in the annular groove 102 forms a triple seal, which greatly increases the sealing effect.

[0036] Preferably, the top of the slider 104 is provided with an annular pressure plate 50, and the outer sealing ring 40 is pressed against the top of the pressure plate 50. The pressure plate 50 is used to contact the outer sealing ring 40 to increase the uniformity of contact between the outer sealing ring 40 and the outer sealing ring 40.

[0037] Preferably, the outer sealing ring 40 has a U-shaped cross-section and is fitted onto the bottom of the annular outer frame 201.

[0038] Preferably, the junction of adjacent sliding frames 105 is provided with mutually cooperating abutting inclined surfaces. When the sliding frame 105 slides inward, the four sets of abutting inclined surfaces abut against each other and the four sliding frames 105 form a ring structure to compress the inner sealing ring 30.

[0039] Preferably, the vertical portion of the inner sealing ring 30 is arched in the middle to form an arched structure. The arched structure can deform under pressure to increase the contact area.

[0040] Preferably, the cover plate 20 is an integrally formed metal structure, with the inner sealing ring 30 and the outer sealing ring 40 respectively fitted onto the bottom of the annular inner frame 202 and the annular outer frame 201. The metal structure is used to conduct heat from the controller and accelerate heat dissipation.

[0041] Preferably, the bottom shell 10 is provided with a wire passage hole 101, and a flexible waterproof plug is provided at the wire passage hole 101. The waterproof plug is used to seal the wire threading position. The foot pedal part 03 is provided with a wire passage groove or wire threading hole, which extends to the wire passage hole 101.
