Description

Technical Field

[0001] The invention relates to a safety system for reducing the collision between a bicycle and a rear vehicle. Background Art

[0002] Cycling not only improves your physical and mental health, it's also good for the planet. However, bicycles often share the road with other vehicles, and improper overtaking by oncoming vehicles can create dangers and make cyclists anxious, which can reduce their willingness to ride on the road.

[0003] Many safety devices, such as reflective jackets, reflective strips, LED lights, etc., have been widely used to increase the safety of bicycle riding. This type of safety device can increase the visibility of bicycles or riders, but it cannot provide instant feedback when nearby vehicles are approaching, so it is not a reliable solution.

[0004] Since bicycles often present a dangerous situation with vehicles approaching from behind or from the side, and the bicycle rider may not be aware of such approach before impact, there is a need for a safety system that automatically detects situations between bicycles and nearby vehicles. Such a system can provide a warning to attract the rider's attention, thereby reducing the risk of the bicycle being hit by a vehicle from behind.

[0005] Some industry insiders have proposed bicycles with blind spot detection (BSD) radars. When the radar detects a vehicle approaching, a vibration motor in the handlebar tube warns the rider. However, the vibration warning provided by the vibration motor is insufficient and may be confused with the vibration of the handlebar caused by the uneven road surface. In addition, the rubber handlebar reduces the intensity of the vibration warning, and the rider's hand may leave the handlebar, resulting in the rider not being able to receive a reliable warning. To solve the above problems, a better safety system is needed. Summary of the invention

[0006] The present invention summary is provided to introduce selected inventive concepts in a simplified form, which concepts will be further described in the detailed description below. The content of the present invention summary and the prior art is not intended to identify the key or essential aspects of the claimed subject matter. In addition, the present invention summary is not intended to be used as an aid to determine the scope of the claimed subject matter.

[0007] In some embodiments, a bicycle safety system includes a radar, a controller, and a warning device. The radar is used to detect signals including one or more parameters of one or more vehicles in the left and right blind spots behind the bicycle. The controller receives the signal from the radar and determines whether to issue a warning based on it. The warning device includes a pipe, a vibration motor, and an impact sounding member. The vibration motor includes a rotating shaft and an eccentric block connected to the rotating shaft, and the rotating shaft and the eccentric block are arranged in the pipe. The impact sounding member includes an elastic member and an impact block, the first end of the elastic member is fixed to the inner wall of the pipe, and the second end of the elastic member is connected to the impact block. When the controller determines that a warning needs to be issued, the controller outputs a control signal to drive the rotating shaft to rotate, the rotation of the rotating shaft drives the eccentric block to rotate and cause vibration, and the eccentric block hits the impact sounding member so that the impact block hits the inner wall to generate an impact force and emit a sound. In this way, the warning device simultaneously provides the rider with three warnings: vibration, impact, and hearing.

[0008] In some embodiments, one warning device is provided at each of one or more of the left handlebar, the right handlebar, the seat, the seat tube, the left pedal shaft, the right pedal shaft, the left crank, and the right crank of the bicycle.

[0009] In some embodiments, the eccentric block strikes the elastic member of the impact sound-generating member, so that the impact block strikes the inner wall to generate an impact force and emit a sound.

[0010] In some embodiments, the eccentric block emits a first sound after striking the impact block of the impact sound-generating member and causes the elastic member to deform. The deformation of the elastic member causes the impact block to hit the inner wall, thereby generating an impact force and emitting a second sound.

[0011] In some embodiments, there are multiple impact sound generating members.

[0012] In some embodiments, the sizes of the impact blocks and / or the elastic members of the plurality of impact sound generating members are different from each other.

[0013] In some embodiments, the elastic member is a spring sheet.

[0014] In some embodiments, the impact sound generating member is a steel ball.

[0015] In some embodiments, the inner wall has a rough surface.

[0016] In some embodiments, the tube has one or more perforations. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiments will be described more fully below with reference to the accompanying drawings, which form a part of this article and show specific exemplary embodiments by way of illustration. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, these embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Therefore, the following detailed description is not intended to be limiting.

[0040] Figure 1 FIG. 2 is a block diagram of a bicycle safety system 1 according to an embodiment of the present invention. Figure 2 for Figure 1 The bicycle safety system 1 is shown as a schematic diagram installed on a bicycle. Figure 1 and Figure 2 The bicycle safety system 1 mainly comprises a radar 10, a controller 11 and a warning device 12. The bicycle safety system 1 is suitable for being installed on a bicycle. In this document, "bicycle" refers to a two-wheeled vehicle that is completely driven by human power or a two-wheeled vehicle with electric auxiliary drive, such as an electric bicycle (e-bike).

[0041] See also Figure 1 and Figure 2 The radar 10 is arranged at a suitable position in front of or behind the bicycle, such as on the supporting structure of the rear seat. The radar 10 may be a blind spot detection (BSD) radar commonly used in automobiles, which continuously detects one or more parameters of one or more vehicles (such as cars or motorcycles, etc.) in the left and right blind spots behind the bicycle, such as the distance between the vehicle and the bicycle, the speed of the vehicle, etc.

[0042] See also Figure 1 and Figure 2 , the controller 11 is arranged at an appropriate position of the bicycle, such as the frame, and receives the signal from the radar 10. Preferably, the controller 11 is electrically connected to the radar 10 through a line and transmits data. The controller 11 may include a battery or may be connected to an external power source. The controller 11 determines whether to issue a warning based on the signal from the radar 10. When a warning is required, the controller 11 outputs a control signal to drive the warning device 12 to issue a warning, and the details will be described as follows.

[0043] Figure 3A and Figure 3B FIG. 1 is a schematic diagram of a warning device 12 according to a preferred embodiment of the present invention. Figure 3A , the warning device 12 mainly includes a vibration motor 120, a pipe 121, and an impact sounding member 122. The vibration motor 120 mainly includes a rotating shaft 1201 and an eccentric block 1202 connected to the rotating shaft 1201. Preferably, the rotating shaft 1201 and the eccentric block 1202 are arranged in the hollow pipe 121. The impact sounding member 122 mainly includes an elastic member 1221 and an impact block 1222. One end of the elastic member 1221 is fixed to the inner wall 1211 of the pipe 121, and the other end is connected to the impact block 1222. The fixing method of one end of the elastic member 1221 to the inner wall 1211 can be welding, screwing, or other methods known in the art. When the elastic member 1221 is not subjected to external force, the impact block 1222 does not contact the inner wall 1211 of the pipe 121. In this embodiment, the elastic member 1221 is a spring, but is not limited to this. Preferably, the pipe 121, the eccentric block 1202, the elastic member 1221, and the impact block 1222 are made of metal or alloy. The material of the elastic member 1221 may be the same as or different from the material of the impact block 1222. In some embodiments, the material of the eccentric block 1202 is non-metal, such as plastic.

[0044] See also Figure 3A When a warning is required, the controller 11 outputs a control signal to drive the rotating shaft 1201 of the vibration motor 120 to rotate. The rotation of the rotating shaft 1201 drives the eccentric block 1202 to rotate, causing vibration due to inertia. Figure 3A As shown, when the rotating shaft 1201 rotates and drives the eccentric block 1202 to rotate, the eccentric block 1202 hits the elastic member 1221 and causes it to deform, so that the impact block 1222 at the end (free end) of the elastic member 1221 hits the inner wall 1211 of the pipe 121, thereby generating an impact force and making a sound. The vibration, impact force, and sound transmitted through the pipe 121 are used to remind the rider to pay attention. Figure 3B As shown, when the eccentric block 1202 is rotated to a certain position, the eccentric block 1202 is separated from the elastic member 1221, so that the impact block 1222 returns to the initial position, that is, returns to the original position where it does not contact the inner wall 1211 of the pipe 121. Therefore, during the rotation of the shaft 1201, if the rotation speed of the shaft 1201 is fixed, the impact block 1222 periodically impacts the inner wall 1211 of the pipe 121 and periodically generates impact force and sounds.

[0045] Reference Figure 3A and Figure 3BPreferably, the controller 11 and the vibration motor 120 are electrically connected through a line and transmit data. According to this embodiment, the warning device 12 simultaneously provides the rider with three warnings: vibration, impact, and sound. In this article, the "sound" emitted by the warning device 12 is a sound wave with an outdoor sound pressure greater than a certain value, such as 75 dB. The controller 11 can classify the warnings into several types, such as three levels, according to the distance between the vehicle and the bicycle. The rotation speed of the shaft 1201 varies according to the level of the warning. For example, the closer the distance between the vehicle and the bicycle, the faster the rotation speed of the shaft 1201.

[0046] Reference Figure 3A and Figure 3B In this embodiment, the pipe 121 is a part of the handlebar tube of the bicycle. That is, the vibration motor 120 and the impact sounding member 122 are arranged in the handlebar tube. The vibration and impact force generated by the warning device 12 are transmitted to the rider by the handlebar of the bicycle, and the sound generated by the impact strengthens the warning effect. In a preferred embodiment, there can be a warning device 12 in each of the left and right handlebar tubes. If a moving vehicle is detected approaching in the left blind spot, the warning device 12 in the left handlebar tube will issue a warning. If a moving vehicle is detected approaching in the right blind spot, the warning device 12 in the right handlebar tube will issue a warning.

[0047] Reference Figure 3A and Figure 3B In other embodiments of the present invention, a warning device 12 may be selectively provided at one or more locations of the bicycle, such as one or more of the positions of the seat, the seat tube (under the seat), the (left, right) pedal shaft, and the (left, right) crank. In some embodiments, in addition to having a warning device 12 in each of the left and right handlebars of the bicycle, a warning device 12 is provided at each of the above-mentioned one or more locations to ensure that the rider can receive the warning. In the above-mentioned one or more locations, if the warning device 12 is installed in the seat, the warning device 12 has an independent pipe 121; if the warning device 12 is installed in the seat tube, the (left, right) pedal shaft, and / or the (left, right) crank, the pipe 121 is a part of the seat tube, the (left, right) pedal shaft, and / or the (left, right) crank.

[0048] Reference Figure 3A and Figure 3BCompared with the warning device of the prior art that sets a vibration motor in the handlebar tube, the warning device 12 of the present application provides a better warning effect. As mentioned above, the vibration motor of the prior art warning device only provides insufficient warning vibration through a single eccentric block. In addition, although the vibration motor itself can also make a sound through the vibration of the eccentric block, its sound pressure is between 50dB and 65dB, and the frequency is between 130Hz and 180Hz, which is difficult for the rider to hear outdoors. In addition to the vibration warning of the eccentric block, the warning device 12 of the present application also provides an impact warning and a sound warning generated by the impact block 1222 hitting the inner wall 1211 of the pipe 121. The rider's body parts, such as hands, buttocks, and / or feet, feel the impact force fed back by the pipe 121. In a typical embodiment, the sound generated by the warning device 12 has a sound pressure of between 75dB and 100dB and a frequency of between 1800Hz and 3800Hz outdoors. Therefore, the rider can easily hear the sound generated by the warning device 12 at the same time.

[0049] Figure 4A FIG. 1 is a schematic diagram of a warning device 12 according to another embodiment of the present invention. Figure 3A and Figure 3B The difference between the embodiments is that there are multiple impact sound generating members 122. For example, Figure 4A The display warning device 12 has a collision sounding member 122A, a collision sounding member 122B, and a collision sounding member 122C. When the rotating shaft 1201 rotates and drives the eccentric block 1202 to rotate, the eccentric block 1202 sequentially strikes the elastic members 1221A, 1221B, and 1221C and causes them to deform, so that the collision blocks 1222A, 1222B, and 1222C sequentially hit the inner wall 1211 of the pipe 121 to generate an impact force and emit a continuous sound. In some embodiments, the collision blocks 1222 and / or the elastic members 1221 of the plurality of collision sounding members 122 have different sizes and can be arranged in the order of collision. For example, in Figure 4B In the example, the impact blocks 1222A, 1222B, and 1222C are all steel balls, and their diameters are 1222A>1222B>1222C (or 1222A<1222B<1222C). Figure 4C In the embodiment, the elastic members 1221A, 1221B, and 1221C are all spring sheets, and the thickness thereof is 1221A>1221B>1221C (or 1221A<1221B<1221C). Figure 3A and Figure 3B In the embodiment of the present invention, the sounds produced by the multiple impact sound-generating members 122 can be continuous, multi-frequency, and / or multi-variable.

[0050] FIG. 5A to FIG. 5BFIG. 1 is a schematic diagram of a warning device 12 according to another embodiment of the present invention. In this embodiment, the warning device 12 has a vibration motor 120, a pipe 121, and an impact sounding member 122. Figure 3A and Figure 3B Compared with the embodiment, the configuration of the impact sound generating member 122 is different. Figure 5A As shown, when the rotating shaft 1201 rotates and drives the eccentric block 1202 to rotate, the eccentric block 1202 strikes the impact block 1222 to generate a first sound and cause the elastic member 1221 to deform. Figure 5B As shown, then, due to the deformation of the elastic member 1221 , the impact block 1222 impacts the inner wall 1211 of the pipe 121 to generate an impact force and emit a second sound.

[0051] Figure 5C FIG. 1 is a schematic diagram of a warning device 12 according to another embodiment of the present invention. Figure 5A and Figure 5B The difference between the embodiments is that the warning device 12 has a plurality of impact sounding members 122, such as impact sounding member 122A, impact sounding member 122B, and impact sounding member 122C. When the rotating shaft 1201 rotates to drive the eccentric block 1202 to rotate, the eccentric block 1202 sequentially strikes the impact blocks 1222A, 1222B, and 1222C to generate a first sound and cause the elastic members 1221A, 1221B, and 1221C to deform, causing the impact blocks 1222A, 1222B, and 1222C to sequentially strike the inner wall 1211 of the pipe 121 to generate an impact force and emit a second sound.

[0052] See also Figure 5C In this embodiment, the impact blocks 1222 and the elastic members 1221 of the plurality of impact sound generating members 122 have the same size. However, in some embodiments, the impact blocks 1222 and / or the elastic members 1221 of the plurality of impact sound generating members 122 have different sizes and can be arranged in the order of collision. For example, Figure 5C In the example, the impact blocks 1222A, 1222B, and 1222C are all steel balls, and their diameters are 1222A>1222B>1222C or 1222A<1222B<1222C. The sounds generated by the multiple impact sounding members 122 can be continuous, multi-frequency, and / or multi-variable.

[0053] Figure 6 FIG. 1 is a schematic diagram of a warning device 12 according to another embodiment of the present invention. In this embodiment, the warning device 12 has a vibration motor 120, a pipe 121, and one or more impact sounding members 122, such as an impact sounding member 122A, an impact sounding member 122B, and an impact sounding member 122C. Figure 5CThe difference between the embodiments is that the elastic members 1221A, 1221B, and 1221C are all springs. When the rotating shaft 1201 rotates to drive the eccentric block 1202 to rotate, the eccentric block 1202 sequentially strikes the impact blocks 1222A, 1222B, and 1222C to generate a first sound and cause the elastic members 1221A, 1221B, and 1221C to deform, causing the impact blocks 1222A, 1222B, and 1222C to sequentially strike the inner wall 1211 of the pipe 121 to generate an impact force and emit a second sound.

[0054] See also Figure 6 In this embodiment, the impact blocks 1222 and the elastic members 1221 of the plurality of impact sound generating members 122 have the same size. However, in some embodiments, the impact blocks 1222 and / or the elastic members 1221 of the plurality of impact sound generating members 122 have different sizes and can be arranged in the order of collision. For example, Figure 6 In the example, the impact blocks 1222A, 1222B, and 1222C are all steel balls, and their diameters may be 1222A>1222B>1222C or 1222A<1222B<1222C. The sounds generated by the multiple impact sounding members 122 may be continuous, multi-frequency, and / or multi-variable.

[0055] Figure 7 FIG. 1 is a schematic diagram of a warning device 12 according to another embodiment of the present invention. Figure 4A The difference between the embodiments is that the inner wall 1211 of the pipe 121 is not smooth but a roughened surface. The roughened inner wall 1211 helps to increase the impact effect. The roughened inner wall 1211 can also be applied to any embodiment of the present application, such as Figure 3A and Figure 3B , Figure 4B and Figure 4C , FIG. 5A to FIG. 5C , Figure 6 In the embodiment of .

[0056] Figure 8 FIG. 1 is a schematic diagram of a warning device 12 according to another embodiment of the present invention. Figure 4A The difference between the embodiments is that the pipe 121 has one or more perforations 1212 to increase the sound pressure and / or variation of the sound emitted by the pipe 121. The pipe 121 with the perforations 1212 can also be applied to any embodiment of the present application, such as Figure 3A and Figure 3B , Figure 4B and Figure 4C , FIG. 5A to FIG. 5C , Figure 6 , Figure 7 In the embodiment of .

[0057] Fig. 9 FIG. 1 is a block diagram of a bicycle safety system 1 according to another embodiment of the present invention. Figure 1 The difference of the system shown is that the controller 11 can also be connected to other devices by wire or wireless means to provide auxiliary warnings to the rider. For example, the bicycle safety system 1 also has a rearview mirror LED 13 installed on the left and right rearview mirrors and / or an LED ring 14 installed on the (left and right) handlebars. The controller 11 is connected to the (left and right) rearview mirror LED 13 and / or the (left and right) LED ring 14 through a line; when a warning needs to be issued, the controller 11 causes the rearview mirror LED 13 and / or LED ring 14 on the corresponding side to emit light corresponding to the warning according to the warning level and / or the blind spot of the source of the warning. Among them, the rearview mirror LED 13 installed on the left and right rearview mirrors can be a plurality of LEDs (light emitting diodes) surrounding the periphery of the rearview mirror, and these LEDs can emit light in sequence, for example, in a clockwise or counterclockwise direction, to increase the warning effect. The color of the light emitted by the LED ring 14 is different for different warning levels.

[0058] See also Fig. 9 The controller 11 may also have a Bluetooth communication module to wirelessly connect to the rider's mobile phone 18 and transmit information to an application on the mobile phone 18. The transmitted information includes warning information and other information, such as maps, real-time images of the rear of the bicycle, and text / symbols / graphics / voice prompts.

[0059] See also Fig. 9 , the rider's mobile phone 18 can be connected to one or more other devices, including earphones 15, helmets 16, and / or speakers 17, via Bluetooth to further provide warning information to the rider. For example, the prompt voice is transmitted to the earphones 15, helmets 16, and / or speakers 17 via Bluetooth. Fig.10 A helmet 16 according to an embodiment of the present invention is shown, and the helmet 16 has a built-in Bluetooth headset and / or Bluetooth speaker (not shown) to receive warning information from a mobile phone 18. In addition, the helmet 16 also has LED lights 160 respectively arranged on both sides of the mask, and according to the warning level and / or the blind spot of the source of the warning, the LED lights 160 on the corresponding side emit light of a corresponding intensity or color corresponding to the warning level.
