Riding safety warning device for self-generating bicycle

Abstract

The utility model discloses a riding safety warning device for a self-power-generation bicycle. The riding safety warning device comprises two mounting covers and a fixing frame which is arranged between the two mounting covers and used for being connected with the bicycle. The utility model relates to the technical field of self-generating bicycles. The impeller can drive the warning frame to rotate in the riding process of the electricity-generating bicycle, so that the noctilucent strips installed on the branches of the warning frame rotate along with the warning frame, the rotating speed of the noctilucent strips is in direct proportion to the moving speed of the self-electricity-generating bicycle, and therefore the dynamic light-emitting effect can be created in the riding state; due to the fact that human eyes are more sensitive to dynamic objects, the continuously-changing light track is more easily captured by the human eyes, meanwhile, the bell can make sounds during rotation, the volume of the bell is kept in direct proportion to the moving speed of the self-generating bicycle, and therefore the bicycle can generate electricity in a low-illumination or even non-illumination environment. The sight of surrounding pedestrians and vehicle drivers is attracted instantly through dazzle light and ringtones, and the warning effect is improved.

Description

Technical Field

[0001] This utility model relates to the field of self-generating bicycle technology, specifically a riding safety warning device for self-generating bicycles. Background Technology

[0002] Self-powered bicycles are becoming increasingly popular as a green mode of transportation. However, safety issues for cyclists are also becoming more prominent, especially at night or in low-light conditions, when bicycles are less visible to other vehicles and pedestrians, increasing the risk of traffic accidents.

[0003] Cycling safety warning devices are devices installed on bicycles to warn passing vehicles at night. However, existing bicycle warning devices have limitations in application. They usually use taillights with reflective effects to reflect light from behind to achieve the warning purpose. However, when pedestrians or electric bicycles behind do not have lighting conditions, such warning devices cannot function effectively, making it difficult for bicycles to be clearly identified and posing certain safety hazards.

[0004] Therefore, this utility model provides a riding safety warning device for self-generating bicycles to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a riding safety warning device for self-generating bicycles, solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a riding safety warning device for a self-generating bicycle, comprising two mounting covers and a fixing frame disposed between the two mounting covers for connecting the bicycle;

[0007] The mounting cover is equipped with a rotating shaft with one end connected to an impeller and the other end connected to a warning frame. The impeller can rotate when the bicycle is moving.

[0008] Several luminous strips are arranged at an angle, and these luminous strips are distributed around the warning frame.

[0009] The bell is elastically connected to the rotating shaft via a connecting frame. The faster the impeller rotates, the larger the rotation radius of the bell.

[0010] Preferably, the side of the mounting cover near the impeller has a funnel structure, and the side of the mounting cover near the warning frame has a horn structure.

[0011] Preferably, the number of luminous strips is three, and they are evenly distributed on the warning frame.

[0012] Preferably, the connecting frame consists of an extension, a slide rod, a slider, and a spring. The extension is sleeved on the rotating shaft, the slide rod is disposed on the extension, and the slider is slidably sleeved on the slide rod and is elastically connected to the inner wall of the extension through the spring.

[0013] Preferably, the mounting cover has several reflective strips on the outer side near the luminous strip, and the several reflective strips are arranged at equal intervals.

[0014] Preferably, a support plate that is rotatably connected to the rotating shaft is fixed inside the mounting cover, and the support plate has a hollow structure.

[0015] Beneficial effects

[0016] This invention provides a riding safety warning device for a self-generating bicycle. Compared with the prior art, it has the following advantages:

[0017] (1) The self-generating bicycle riding safety warning device can drive the warning frame to rotate during the riding of the self-generating bicycle through the impeller, so that the luminous strips installed on each branch of the warning frame rotate accordingly, and the rotation speed is proportional to the speed of the self-generating bicycle, thus creating a dynamic luminous effect during riding. Since the human eye is more sensitive to dynamic objects, this continuously changing light trajectory is easier for the human eye to capture; at the same time, the bell can make a sound when rotating, and its volume is also proportional to the speed of the self-generating bicycle, so that in low light or even no light environment, the glare and the sound of the bell can instantly attract the attention of pedestrians and drivers of vehicles, thus improving the warning effect.

[0018] (2) The self-generating bicycle riding safety warning device increases the wind speed entering the mounting cover by setting the front end of the mounting cover to a funnel structure, thereby increasing the speed of the impeller. At the same time, the rear end of the mounting cover is set to a horn shape, which can easily amplify the sound of the bell, making its propagation range wider and the warning effect better.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 2 , Figure 3 and Figure 5 A self-generating bicycle riding safety warning device includes two mounting covers 1 and a fixing frame 2 set between the two mounting covers 1 for connecting the bicycle. The side of the mounting cover 1 near the impeller 4 has a funnel structure, which can increase the wind speed entering the interior of the mounting cover 1, thereby increasing the rotation speed of the impeller 4. The side of the mounting cover 1 near the warning frame 5 has a horn structure, and the horn shape can easily amplify the sound of the bell 8, making its propagation range wider and the warning effect better.

[0028] Figures 1 to 3 The mounting cover 1 is equipped with a rotating shaft 3, which is connected to an impeller 4 at one end and a warning frame 5 at the other end. The impeller 4 can rotate when the bicycle is moving. The impeller 4 can drive the warning frame 5 to rotate during the riding of the generator bicycle, so that the luminous strips 6 installed on each branch of the warning frame 5 rotate accordingly. The rotation speed is proportional to the moving speed of the generator bicycle, so as to create a dazzling effect during riding, which is easy for the human eye to catch. The mounting cover 1 is fixed with a support plate 10 that is rotatably connected to the rotating shaft 3. The support plate 10 has a hollow structure, and the hollow design facilitates the flow of gas.

[0029] Several luminous strips 6 are arranged at an angle and are distributed around the warning frame 5. There are three luminous strips 6, which are evenly distributed on the warning frame 5. The luminous strips 6 arranged at an angle can warn pedestrians and vehicles in different directions when they rotate.

[0030] Figure 3 and Figure 4Bell 8 is elastically connected to the rotating shaft 3 via a connecting frame 9. The faster the impeller 4 rotates, the larger the rotation radius of bell 8 becomes. Bell 8 can make a sound when it rotates. Under the action of centrifugal force, bell 8 will gradually move outward as the generator bicycle moves quickly, thus forming a larger rotation radius and making its sound louder.

[0031] The connecting frame 9 consists of an extension 91, a slide bar 92, a slider 93, and a spring 94. The extension 91 is sleeved on the rotating shaft 3, the slide bar 92 is set on the extension 91, and the slider 93 is slidably sleeved on the slide bar 92. It is elastically connected to the inner wall of the extension 91 through the spring 94. The spring 94 pulls the bell 8, so that its rotation radius can be adaptively increased or decreased during rotation, so that the bell sound matches the riding speed.

[0032] Several reflective strips 7 are provided on the outer side of the mounting cover 1 near the luminous strip 6, and the reflective strips 7 are arranged at equal intervals.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
