Description

Technical Field

[0001] This application relates to the technical field of electric vehicle braking components, and particularly to a smart linkage system for helmet steering and braking of an electric vehicle integrated with a helmet. Background Art

[0002] As a means of transportation powered by electricity, electric vehicles are loved by the general public for their small size, portability, and convenient parking. They are the main means of transportation for people when traveling short distances or in crowded sections. In recent years, they have been very widely popularized in our country.

[0003] However, due to the wide popularity of electric vehicles, a large number of electric vehicles have appeared on the road. Therefore, in order to ensure the safety of the drivers and passengers, helmets have now become essential protective facilities for drivers and passengers. However, the existing helmets and electric vehicles are independent of each other and cannot give corresponding reminders to the following vehicles according to the driving changes of the electric vehicle. Especially in complex and crowded sections, when there are many electric vehicles on the road, because the driving change lights of the electric vehicle itself are located below the electric vehicle, they are extremely vulnerable to occlusion, which affects the judgment of the following vehicle. As a result, there are significant safety hazards when the electric vehicle is driving on the road.

[0004] At the same time, since the speed regulation and braking of the electric vehicle are set on the handlebar and both require the right hand to operate, when the driver changes the driving and decelerates the electric vehicle by operating the brake handle, the speed regulation throttle is always in a specific speed control position, resulting in a lot of ineffective power output when the electric vehicle decelerates, which greatly affects the battery life of the electric vehicle.

[0005] Moreover, when the brake handle is released, because the speed regulation throttle is always in a specific speed control position, the electric vehicle is prone to the phenomenon of "sudden surging", further reducing the safety, stability, and reliability of the electric vehicle when driving.

[0006] Therefore, there is an urgent need for a smart braking system for electric vehicles to solve the above-mentioned safety hazards existing in the existing electric vehicles during driving. Summary of the Invention

[0007] The present application proposes a helmet steering and braking intelligent linkage system based on a helmet-integrated electric vehicle, which has the function of feeding back the driving changes of the electric vehicle to the following vehicle through the lighting changes in the helmet, and will not affect the judgment of the following vehicle due to occlusion in a crowded section, with high safety and reliability. At the same time, when the electric vehicle brakes due to driving changes, it can automatically reduce the output power of its motor, effectively avoiding its ineffective power output and improving the endurance of the electric vehicle. This is used to solve the problem that the existing helmets and electric vehicles are independent of each other and cannot give corresponding reminders to the following vehicle according to the driving changes of the electric vehicle. Especially in a complex and crowded section, when there are many electric vehicles on the road, because its own driving change lights are located below the electric vehicle, it is very easy to be blocked and affect the judgment of the following vehicle, thus making the electric vehicle have a large potential safety hazard when driving on the road. At the same time, because the speed regulation and braking of the electric vehicle are set on the handle and both require the right hand to operate, when the driver changes the driving and decelerates the electric vehicle through the brake handle, the speed regulation throttle is always in a specific speed control state, resulting in more ineffective power output when the electric vehicle decelerates and a shorter endurance mileage.

[0008] To achieve the above object, the present application adopts the following technical solutions: A helmet steering and braking intelligent linkage system based on a helmet-integrated electric vehicle, including a lighting group, a Bluetooth module, and a charging module:

[0009] The lighting group is fixedly installed on the back of the helmet and is triggered when the driving state of the electric vehicle body changes to remind the following vehicle;

[0010] The Bluetooth module includes a receiving module arranged inside the electric vehicle body and a transmitting module arranged inside the handle;

[0011] The charging module is fixedly installed at the bottom of the helmet and is adapted to a charging interface arranged on the seat cushion of the electric vehicle body.

[0012] Furthermore, the handle also includes a speed regulation throttle. The speed regulation throttle is fixedly installed on the electric vehicle body through a fixed shaft movably sleeved in its inner cavity. A circular groove is opened on one side of the outer surface of the fixed shaft, and a speed regulation ring in contact with the end face of the speed regulation throttle is movably sleeved inside the circular groove. A magnetic strip is fixedly sleeved on one side of the outer surface of the speed regulation ring. A linkage sleeve is movably sleeved on the other side of the outer surface of the fixed shaft. The outer surface of the linkage sleeve is movably sleeved with an end cover fixedly connected to the electric vehicle body. A Hall element is fixedly installed at the top of one side of the inner wall of the end cover and directly above the magnetic strip.

[0013] Furthermore, a circumferential transmission connection is formed between an elastic torsion piece inside the speed regulation ring and the circular groove on the fixed shaft, and one end of the linkage sleeve is movably sleeved inside the speed regulation ring.

[0014] Further, one side of the annular groove on the fixed shaft is movably sleeved with a compression spring, and an axial transmission connection is formed between the speed regulation ring and the end face of the annular groove through the compression spring.

[0015] Further, the top of the end cover is movably connected with the brake handle through a pin shaft, and a dial is pin-connected to one side of the bottom end of the brake handle. The bottom end of the dial penetrates and extends into the inside of the linkage sleeve, and is clamped with a wedge block arranged inside the linkage sleeve.

[0016] Further, a set of helical teeth that are matched and clamped with each other are respectively arranged on the right side of the speed regulation ring and the end face where the speed regulation handle contacts it.

[0017] Further, the outer surface of the speed regulation handle is provided with anti-slip lines. When the electric vehicle brakes and decelerates, due to the elastic force of the elastic torsion piece on the speed regulation ring and its magnetic strip, it can return to the initial position state, so that the speed regulation handle rotates unidirectionally during operation.

[0018] The present invention application has the following technical effects:

[0019] 1. A helmet steering and braking intelligent linkage system based on a helmet-integrated electric vehicle provided by the present application, for the settings of the lighting group, Bluetooth module and charging module on the helmet. When changing the driving state of the electric vehicle, the change of the lighting group in the helmet can be fed back to the following vehicle, so that when the electric vehicle is driving on a complex road section, it will not affect the judgment of the following vehicle due to the relatively low position of its own driving change lights being blocked, effectively improving the safety and reliability of the electric vehicle during driving.

[0020] 2. A helmet steering and braking intelligent linkage system based on a helmet-integrated electric vehicle provided by the present application, for the settings of the fixed shaft and its structure thereon. When the electric vehicle brakes, the rotation speed of the motor on the electric vehicle body can be automatically reduced, thereby reducing its ineffective power output and effectively increasing the cruising range of the electric vehicle. And when the brake handle is released, because the driving speed of the electric vehicle is relatively low, the phenomenon that the electric vehicle is prone to "sudden rush" is effectively avoided, further improving the safety of the electric vehicle during driving.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0034] As Figure 1 shown, a helmet steering and braking intelligent linkage system based on a helmet-integrated electric vehicle includes a lighting group, a Bluetooth module, and a charging module:

[0035] The lighting group is fixedly installed on the back of the helmet 3 and is triggered when changing the driving state of the electric vehicle body 1 to remind the following vehicle;

[0036] Among them, the lighting group includes two groups of yellow lights with arrows and a gradient brake red light, and the yellow lights in the corresponding direction are triggered when the electric vehicle body 1 turns left or right, and the red light is turned on when the braking member 2 is triggered;

[0037] The Bluetooth module includes a receiving module disposed inside the electric vehicle body 1 and a transmitting module disposed inside the handle 4. When changing its driving state, the action signal of the button on the handle 4 can be synchronously fed back to the lighting group on the helmet 3 through the Bluetooth module, and different lights are turned on to give corresponding reminders to the following vehicle.

[0038] The charging module is fixedly installed at the bottom end of the helmet 3 and is adapted to the charging interface disposed on the seat cushion of the electric vehicle body 1. When the electric vehicle is not being ridden, the helmet 3 can be placed on its seat cushion, and at the same time, it is charged using the power supply in the electric vehicle.

[0039] Among them, it also includes a power supply system fixedly installed inside the helmet 3, which can provide corresponding power support for the lighting group and the Bluetooth module on it when the rider wears the helmet 3.

[0040] As Figure 2 shown, in this technical solution, the handle 4 further includes a speed control grip 6. The speed control grip 6 is fixedly installed on the electric vehicle body 1 through a fixed shaft 5 movably sleeved in its inner cavity. As Figure 4 shown, a circular groove is formed on one side of the outer surface of the fixed shaft 5, and a speed control ring 7 in contact with the end face of the speed control grip 6 is movably sleeved inside the circular groove. As Figure 5 shown, a magnetic strip 10 is fixedly sleeved on one side of the outer surface of the speed control ring 7. A linkage sleeve 11 is movably sleeved on the other side of the outer surface of the fixed shaft 5. The outer surface of the linkage sleeve 11 is movably sleeved with an end cap 13 fixedly connected to the electric vehicle body 1. As Figure 8 、 Figure 9 shown, a Hall element 14 is fixedly installed at the top of one side of the inner wall of the end cap 13 and directly above the magnetic strip 10. When the speed control grip 6 is rotated to drive the speed control ring 7 to rotate, the driving speed of the electric vehicle body 1 is controlled through the magnetic field signal detected and fed back by the Hall element 14.

[0041] As Figure 6 shown, in this technical solution, an elastic torsion piece 8 is provided inside the speed control ring 7 to form a circumferential transmission connection with the circular groove on the fixed shaft 5, and one end of the linkage sleeve 11 is movably sleeved inside the speed control ring 7. Therefore, the speed control ring 7 can rotate along the central axis of the fixed shaft 5 under the elastic force of the elastic torsion piece 8.

[0042] As Figure 3 shown, a compression spring 9 is movably sleeved on one side of the circular groove on the fixed shaft 5, and an axial transmission connection is formed between the speed control ring 7 and the end face of the circular groove through the compression spring 9, thereby increasing the frictional resistance between the speed control grip 6 and the speed control ring 7. When the speed control grip 6 is rotated, the speed control ring 7 can be synchronously driven to rotate accordingly.

[0043] In the present technical solution, the top of the end cover 13 is movably connected to the brake handle 15 through a pin shaft, and a paddle 16 is pinned to one side of the bottom end of the brake handle 15, and the bottom end of the paddle 16 penetrates and extends to the inside of the linkage sleeve 11, such as Figure 7 As shown, it is mutually engaged with the wedge block 12 arranged inside the linkage sleeve 11, and when the brake handle 15 is pressed, the linkage sleeve 11 and the speed regulating ring 7 thereon are forced to move to the right side under the action of the paddle 16, so that the right side of the speed regulating ring 7 and the end face of the speed regulating handle 6 are no longer in contact, and then under the elastic force of the elastic torsion plate 8, the speed regulating ring 7 rotates in the opposite direction, so that the electric vehicle body 1 can automatically reduce its running speed when braking, reduce its invalid power output, and greatly improve the cruising range of the electric vehicle.

[0044] like Figure 5 As shown, in the present technical solution, a group of mutually engaging bevel teeth 17 are respectively provided on the right side of the speed regulating ring 7 and the end surface of the speed regulating handle 6 in contact therewith, thereby effectively increasing the interaction force between the speed regulating handle 6 and the speed regulating ring 7 with the elastic force of the compression spring 9, and preventing slippage between the speed regulating handle 6 and the speed regulating ring 7 during the rotation of the speed regulating handle 6, without affecting the speed control accuracy of the electric body 1.

[0045] In the present technical solution, the outer surface of the speed regulating handle 6 is provided with anti-slip grooves, and when the electric vehicle is braked and decelerated, the speed regulating ring 7 and the magnetic strip 10 thereon can be restored to the initial position state under the elastic force of the elastic torsion plate 8, thereby making the speed regulating handle 6 in a unidirectional rotating state during operation.
