Description

Technical Field

[0001] The present application relates to the technical field of electric power-assisted bicycles, and in particular to a rear vehicle reminder system. Background Art

[0002] With the popularity of electric bicycles, their safety issues are becoming increasingly prominent. At present, there are some safety auxiliary devices for electric bicycles on the market, such as rearview mirrors, flashing lights, etc., but these devices are still insufficient in reminding riders to pay attention to vehicles coming from behind.

[0003] In the prior art, rearview mirrors are usually used to observe vehicles coming from behind, but rearview mirrors have blind spots and riders may not always pay attention to the rearview mirrors during driving. In addition, some electric bicycles are equipped with flashing lights to alert vehicles behind, but this method has limited effect in reminding riders to pay attention to vehicles coming from behind. Utility Model Content

[0004] In order to improve the safety of cyclists during riding, the present application provides a rear vehicle reminder system.

[0005] The following technical solution is adopted in the rear vehicle warning system provided in the present application:

[0006] A rear vehicle reminder system includes an electric vehicle handlebar and a taillight. The electric vehicle handlebar includes a balance bar, a display screen arranged on the top of the balance bar shaft, and handlebars arranged at both ends of the balance bar. A fixing box is arranged between the display screen and the balance bar. A controller is arranged in the fixing box. Each of the handlebars is provided with a feedback mechanism for providing a warning message to the rider, and the feedback mechanism is electrically connected to the controller. The feedback mechanism includes a vibration sleeve mounted on the handlebar and a warning light strip for warning arranged on the vibration sleeve. One taillight is arranged at the left rear and right rear of the electric vehicle, and each of the taillights is provided with a rangefinder electrically connected to the controller.

[0007] By adopting the above technical solution, the taillights on the electric bicycle detect the distance of the rear vehicle in the corresponding direction through the rangefinders on the left and right sides, and transmit the electric signal to the controller for calculation, so as to judge the degree of danger of the vehicle, and display the real-time distance and speed of the rear vehicle to the rider through the data on the display screen. Since the rider may ignore the prompts on the display screen due to focusing on the road conditions ahead during riding, when calculating the degree of danger of the rear vehicle, the controller also transmits the warning information to the vibration sleeve and the warning light strip on the handlebar through electric signals. According to the degree of danger of the rear vehicle, the vibration frequency of the vibration sleeve and the flashing frequency of the warning light strip change accordingly, and then the warning information of the degree of danger is synchronously conveyed to the rider through the dual stimulation of touch and vision.

[0008] Optionally, the vibration sleeve is made of a flexible material, and a cavity is opened inside the vibration sleeve, an electromagnetic coil is arranged on the inner wall of the cavity facing the handle, a flexible magnetic cloth is arranged on the inner wall of the cavity away from the handle, the inner wall of the cavity away from the handle is a metal shrapnel, the flexible magnetic cloth is fixedly arranged on the inner bottom of the metal shrapnel, a control electrode connected to both ends of the electromagnetic coil is arranged in the cavity, and the warning light is electrically connected to the control electrode.

[0009] By adopting the above technical solution, the electromagnetic coil is combined with a flexible magnetic cloth and a spring to achieve miniaturization and low power consumption of the vibration feedback device in the vibration sleeve. The vibration feedback device in the vibration sleeve is entirely made of flexible materials and can be adapted to handles of different sizes.

[0010] Optionally, a plurality of protrusions are arranged on the surface of the metal spring away from the handle.

[0011] By adopting the above technical solution, the plurality of protrusions arranged on the top wall of the metal spring away from the handlebar increase the vibration points for transmitting the vibration feeling between the vibration sleeve and the palm of the rider.

[0012] Optionally, some of the protrusions are made of rubber.

[0013] By adopting the above technical solution, the flexible material of the rubber convexities provides the rider with a more comfortable and natural vibration feedback experience, and increases the friction between the rider's hand and the vibration sleeve when the rider holds the handlebar, so that the rider can better control the stability of the handlebar of the electric vehicle when holding the handlebar, thereby improving the rider's safety and stability during riding.

[0014] Optionally, the vibration sleeve can be unfolded and provided with Velcro for winding and bonding, the Velcro comprising a velvet surface on the flatly unfolded vibration sleeve located on one side of the metal shrapnel and an adhesive surface on the vibration sleeve facing away from the metal shrapnel and away from the velvet surface.

[0015] By adopting the above technical solution, the vibration cover can fit handlebars of different sizes and be firmly wrapped around the handlebars. The head and tail of the vibration cover can be fixed by Velcro, which can provide the rider with a more comfortable and natural vibration feedback experience.

[0016] Optionally, the warning light belt is movably connected to the vibration sleeve, a plurality of positioning elastic belts are provided on the vibration sleeve corresponding to the warning light belt, and the warning light belt is jointly inserted between the plurality of positioning elastic belts and the metal shrapnel.

[0017] By adopting the above technical solution, the warning light strip and the vibration sleeve are independently positioned by using a plurality of positioning elastic bands to prevent the warning light strip from deviating and sliding during driving, thereby improving the warning light strip.

[0018] Optionally, a buckle is provided at the connecting portion between the head and tail sections of the warning light strip.

[0019] By adopting the above technical solution, the head and tail sections of the warning light strip can be quickly fixed by buckles, which makes it easy to repair and replace the warning light strip.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The taillights on the electric bicycle detect the distance of the vehicle coming from behind in the corresponding direction through the rangefinders on the left and right sides, and transmit the electric signals to the controller for calculation, so as to judge the degree of danger of the vehicle coming from behind, and show the real-time distance and speed of the vehicle coming from behind to the rider through the data on the display screen. Since the rider may ignore the prompts on the display screen due to focusing on the road conditions ahead during riding, when calculating the degree of danger of the vehicle coming from behind, the controller will also synchronously transmit the warning information to the vibration sleeve and warning light strip on the handlebar through electric signals. According to the degree of danger of the vehicle coming from behind, the vibration frequency of the vibration sleeve and the flashing frequency of the warning light strip will change accordingly, and then the warning information of the degree of danger will be synchronously conveyed to the rider through the dual stimulation of touch and vision;

[0022] 2. The electromagnetic coil is combined with flexible magnetic cloth and springs to achieve miniaturization and low power consumption of the vibration feedback device in the vibration sleeve. The vibration feedback device in the vibration sleeve is made entirely of flexible materials and can be adapted to handles of different sizes.

[0023] 3. The plurality of protrusions arranged on the top wall of the metal spring away from the handlebar increase the vibration points for transmitting the vibration feeling between the vibration sleeve and the palm of the rider. BRIEF DESCRIPTION OF THE DRAWINGS
