Description

Technical Field

[0001] The utility model relates to a bicycle warning device, in particular to a bicycle warning wind chime. Background Art

[0002] The speed of a bicycle is generally between 16 and 32 kilometers per hour, and the speed of a road bicycle may reach 30 to 48 kilometers per hour or even higher. In order to warn passers-by, the commonly used method is to install a manual bicycle bell.

[0003] However, current warning devices require more or less human intervention to achieve the warning effect. In some cases, when the vehicle speed is very fast, the rider needs to operate in a short time. Due to the difference between the operating speed and the reaction speed, it often fails to play a warning role in many scenarios. Secondly, the rider has no awareness of his own speed and needs a tool to feedback the instant speed. However, in many scenarios, people cannot feedback the instant speed by observing the instrument. Therefore, it is particularly important to manufacture a device with automatic warning sound, timely feedback of the instant speed and stable sound. Utility Model Content

[0004] In order to solve the above problems or at least partially solve the above problems, an embodiment of the utility model provides a bicycle warning wind chime that automatically warns passers-by and prompts cyclists of their riding speed. This is achieved by driving a percussion tube to rotate through fan blades. The bicycle warning wind chime is equipped with fan blades, percussion tubes, springs, and percussion wheels. Different warning sounds are generated and the rider's speed is fed back through the relative rotation and displacement of its components.

[0005] The utility model discloses a bicycle warning wind chime, which comprises a front fixing cap, fan blades, a knocking tube, a spring, a central axis, a knocking wheel, a rear bell body, a front bell body and a fixing device.

[0006] The knocking tube includes a tube body, a knocking hammer, and a spring, which are fixedly connected. The overall appearance of the knocking wheel is a trapezoidal column, which is subdivided into a semi-arc surface and a semi-right angle gear structure. The front fixing cap is fixed to the front of the central axis, the fan blade is placed behind the front fixing cap, and the fan blade is placed outside the central axis. The fan blade can rotate and move around the central axis.

[0007] In some embodiments, the knocking tube is placed outside the central axis, and the knocking tube can rotate and move around the central axis. The spring is placed outside the central axis, inside the knocking tube, and in front of the knocking wheel.

[0008] In some embodiments, the striking wheel is fixed to the outside of the central axis, the central axis is fixed to the inside of the rear bell body, the rear bell body is fixed to the rear of the front bell body by threads, and the front bell body is fixed above the fixing device.

[0009] In some embodiments, the fan blade is fixedly connected to the knocking tube, and the two can synchronously rotate and move relative to the central axis.

[0010] And / or, the knocking tube is placed outside the knocking wheel, and contacts the knocking wheel through the spring piece and the knocking hammer inside the knocking tube; the front fixing cap, the fan blades, the knocking tube, the spring, the center axis, and the knocking wheel are placed together inside the cavity surrounded by the rear bell body and the front bell body.

[0011] In some embodiments, the fan blades and the knocking tube can be displaced forward and backward relative to the central axis and the knocking wheel due to changes in wind pressure.

[0012] Compared with the prior art, the technical solution provided by the embodiment of the utility model has the following advantages:

[0013] The embodiment of the utility model provides a bicycle warning wind chime that generates different warning sounds by relative mechanical movement, without the need for other sources of energy, and is automatically completed by the change of speed during the riding process of the cyclist;

[0014] When the vehicle speed reaches a certain expected speed, a warning sound can be provided without manual operation, and different sounds can be used to remind the rider of the current vehicle speed, so that the rider can better understand his or her own driving conditions. Therefore, it has good applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0027] like Figure 1 As shown, this embodiment provides a bicycle warning wind chime, including a front fixing cap 1, fan blades 2, a knocking tube 3, a spring 4, a central axis 5, a knocking wheel 6, a rear bell body 7, a front bell body 8, and a fixing device 9.

[0028] like Figure 6 As shown, the knocking tube 3 includes a tube body 31, a knocking hammer 32, and a spring 33, which are fixedly connected.

[0029] like Figure 5 As shown, the overall appearance of the knocking wheel 6 is a trapezoidal column, which is subdivided into a semi-arc surface and a semi-right angle gear structure.

[0030] like Figure 1As shown, the front fixing cap 1 is fixed to the front part of the central axis 5, the fan blade 2 is placed behind the front fixing cap 1, the fan blade 2 is placed outside the central axis 5, the fan blade 2 can rotate and displace around the central axis 5, the knocking tube 3 is placed outside the central axis 5, the knocking tube 3 can rotate and displace around the central axis 5, the spring 4 is placed outside the central axis 5 in front of the knocking wheel 6 inside the knocking tube 3, and the position of the knocking tube 3 relative to the knocking wheel 6 can be adjusted together with the pressure change of the wind pressure acting on the fan blade 2.

[0031] like Figure 1 , 2 As shown in , 4 and 7 , the striking wheel 6 is fixed to the outside of the central axis 5 , the central axis 5 is fixed to the inside of the rear bell body 7 , the rear bell body 7 is fixed to the rear of the front bell body 8 by threads, and the front bell body 8 is fixed above the fixing device 9 .

[0032] like Figure 7 As shown, the fan blade 2 is fixedly connected to the knocking tube 3, and the two can synchronously rotate and move relative to the central axis 5.

[0033] like Figure 7 As shown, the knocking tube 3 is placed outside the knocking wheel 6 and contacts the knocking wheel 6 through the spring piece 33 and the knocking hammer 32 inside the knocking tube 3.

[0034] like Figures 1 to 4 As shown, the front fixing cap 1, the fan blades 2, the knocking tube 3, the spring 4, the central axis 5, and the knocking wheel 6 are placed together in the cavity surrounded by the rear bell body 7 and the front bell body 8.

[0035] When implementing

[0036] Reference Figures 1 to 7 As shown, during bicycle riding, the wind pressure change in front of the bicycle warning wind chime and the reaction force of the spring 4 control the fan blade 2 to strike the tube 3 to move forward and backward, and different position changes occur relative to the striking wheel 6;

[0037] The wind pressure causes the fan blades 2 to drive the knocking tube 3 to rotate together, and the rotation speed is determined by the wind pressure;

[0038] The striking hammer 32 inside the striking tube 3 performs a reciprocating striking motion on the striking wheel 6 through the elastic deformation of the spring piece 33 and the position change of the tube body 31 relative to the striking wheel 6. The striking wheel 6 is fixed together with the central axis 5 inside the rear bell body 7. The vibration of the striking wheel 6 drives the bell bodies 7 and 8 to vibrate and produce sound, thereby generating a warning sound.

[0039] In addition, the frequency of the vibration of the entire bell body will change with the change in the rotation speed of the fan blade 2, and the displacement change of the fan blade 2 from front to back will increase the vibration intensity, thereby feeding back the speed change of the cyclist.
