Description

[Technical Field]

[0001] This invention relates to locomotive warning systems; in particular, it refers to a locomotive warning system capable of providing proactive safety warnings. [Previous Technology]

[0002] It is known that in order to avoid traffic accidents involving collisions, motorcycles usually use taillights to warn vehicles behind them. However, for motorcycle drivers, judging the distance by only seeing the taillights of the motorcycle in front is not timely or accurate enough. In addition, motorcycle drivers also have the same problem of judging the distance by observing the vehicles behind them through the rearview mirror, which is not timely or accurate enough and can easily lead to rear-end collisions and other accidents.

[0003] In summary, existing motorcycle warning devices do not have the function of active safety warning during use. When other vehicles approach, they cannot remind the motorcycle driver in a timely and effective manner. Therefore, conventional motorcycle warning devices still need to be improved. [Summary of the Invention]

[0004] In view of this, the purpose of the present invention is to provide a motorcycle warning system with an active safety warning function. When other vehicles or foreign objects approach, it can promptly and effectively remind the motorcycle driver, thereby improving the motorcycle driver's driving safety.

[0005] To achieve the above objectives, the present invention provides a motorcycle warning system, which is installed on a motorcycle and includes a detection device, a quick-release base, and a warning module. The detection device includes a housing and a detection radar, which is disposed in the housing. The quick-release base is used to attach to the motorcycle, and the housing is detachably attached to the quick-release base. The warning module is disposed on a rearview mirror of the motorcycle and includes a controller and a warning device that are electrically connected. The detection radar is signal-connected to the controller, and the controller receives a detection signal emitted by the detection radar and controls the warning device to operate according to the detection signal.

[0006] The effect of the present invention is that, through the detection radar, when other vehicles or objects approach the motorcycle, the controller receives the detection signal emitted by the detection radar and controls the warning device to operate according to the detection signal. In this way, the motorcycle driver can be reminded in a timely and effective manner that other vehicles or objects are approaching the motorcycle, thereby achieving the effect of active safety warning. In addition, through the design of the housing being detachably combined with the quick-release base, the user can quickly remove the detection device or install it on the quick-release base on the motorcycle.

Implementation Method

[0007] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to Figures 1A to 8, which show a preferred embodiment of the motorcycle warning system 1 of the present invention. The motorcycle warning system 1 is installed on a motorcycle M and includes a detection device 10, a quick-release base 20, and a warning module 30.

[0008] As shown in Figures 3 and 6, the detection device 10 includes a housing 12 and a detection radar 14. The detection radar 14 is disposed in the housing 12 and is a 60 GHz millimeter-wave radar. The quick-release base 20 is used to attach to the motorcycle M. The housing 12 is attached to the quick-release base 20 in a detachable manner. In this embodiment, an adhesive 22 is provided on one side of the quick-release base 20. The adhesive 22 can be, for example, a strong double-sided tape. The quick-release base 20 can be attached to the body of the motorcycle M through the adhesive 22. The quick-release base 20 has a mounting hole 20a for setting a stud 24 or screw to lock the quick-release base 20 to the motorcycle M. In this way, the quick-release base 20 can be more securely attached to the motorcycle M.

[0009] Furthermore, the quick-release base 20 has a connecting portion 20b on the side opposite to where the adhesive piece 22 is provided. This connecting portion 20b allows for detachable connection with the housing 12 of the detection device 10. For example, the side of the housing 12 that connects to the connecting portion 20b may have a fastener for engaging with the connecting portion 20b. This allows the user to quickly detach or install the detection device 10 onto the quick-release base 20 on the motorcycle M. It should be further noted that the housing 12 can be detachably connected to the quick-release base 20 in any manner, not limited to the connection method described in this embodiment.

[0010] In this embodiment, as shown in FIG1A, the number of detection devices 10, 10', 10'' and quick-release bases 20, 20', 20'' is multiple. The quick-release bases 20 are respectively disposed at different positions on the left side panel, right side panel, and front side panel of the motorcycle M. The detection devices 10, 10', 10'' are correspondingly coupled to the quick-release bases 20, 20', 20'', thereby allowing them to be installed on the left side panel, right side panel, and front side panel of the motorcycle M. The quick-release bases 20 located on the front side body panels and other different positions are attached to the body by means of the aforementioned bonding and screwing. In other embodiments, the quick-release bases can also be located on the rear side body of the motorcycle. The quick-release bases can be attached to the rear side body of the motorcycle by means of a fixing bracket. For example, one end of the fixing bracket can be attached to the license plate, and the other end is for bonding with the bottom connecting piece of the quick-release base and locking with studs or screws.

[0011] In this embodiment, the example is that there are multiple detection devices 10 and quick-release bases 20. In other embodiments, the number of detection devices 10 and quick-release bases 20 may be one or more.

[0012] Each of the detection devices 10 includes a battery 16 and a charging circuit 18 (see FIG. 6) disposed in the housing 12. The battery 16 supplies the electrical energy required by the detection device 10. The battery 16 is a rechargeable battery and is connected to the charging circuit 18. See FIG. 3. The housing 12 has a charging port 10a for connecting an external power source to charge the battery 16. The housing 12 has a shield 121 that is movably disposed in the charging port 10a to close or open the charging port 10a. Thus, when the user wants to charge the battery 16, the user can move the shield 121 from the position of closing the charging port 10a (see FIG. 4A) to the position of not covering the charging port 10a to facilitate the connection of the external power source to the charging port (see FIG. 3), and vice versa. This is to prevent rainwater or moisture from entering the charging port 10a and further achieve the effect of waterproofing. In addition, in this embodiment, as shown in FIG4B, a track 10b is provided on each of the opposite sides of the opening of the charging port 10a for engaging with the shield 121. The shield 121 is made of elastic soft CR rubber material. The track 10b is provided with track ribs 10c. Thus, when the shield 121 is placed on the track 10b, the shield 121 can move along the track 10b. The engagement between the shield 121 and the track ribs 10c can further enhance the waterproof effect.

[0013] It should be further noted that in this embodiment, the power required by the detection device 10 is supplied by a rechargeable battery. In other embodiments, the power required by the detection device 10 can also be supplied by a disposable battery or by the vehicle's battery, which can achieve the same effect of supplying the power required by the detection device 10.

[0014] As shown in Figure 2, the warning module 30 is disposed in one of the rearview mirrors B of the motorcycle M. In this embodiment, the warning module 30 is described as being disposed in the right rearview mirror B of the motorcycle M. In other embodiments, the warning module 30 may also be disposed in the left rearview mirror, and is not limited to being disposed in the right rearview mirror of the motorcycle. Furthermore, the rearview mirror B has a housing and a lens. The warning module 30 is disposed in the receiving space between the housing and the lens, and the warning module 30 can be powered by the battery of the motorcycle M.

[0015] As shown in Figure 6, the warning module 30 includes a controller 32 and a warning device 34 electrically connected. The controller 32 may be a microcontroller unit (MCU). The detection radar 14 is signal-connected to the controller 32. The controller 32 receives a detection signal emitted by the detection radar 14 and controls the warning device 34 to operate according to the detection signal. For example, when the detection radar 14 detects that other vehicles or objects are approaching the motorcycle, the controller 32 receives the detection signal emitted by the detection radar 14 and controls the warning device 34 to operate according to the detection signal. In this way, the motorcycle driver can be reminded in a timely and effective manner that other vehicles or objects are approaching the motorcycle, thereby achieving the effect of active safety warning.

[0016] In addition, since this embodiment is equipped with a plurality of detection devices 10, 10', 10'', and the detection radars 14 of these detection devices 10 are respectively connected to the controller 32, when the detection radar 14 detects that other vehicles or objects are approaching the motorcycle from the left side, right side and front side of the motorcycle, the controller 32 can receive the corresponding detection signals emitted by each detection radar 14 and control the warning device 34 to operate according to the corresponding detection signals emitted by each detection radar 14. In this way, the effect of active safety warning can be achieved in different directions, thereby further improving the driver's driving safety.

[0017] As shown in Figure 2, the warning device 34 includes a plurality of warning lights. In this embodiment, the warning lights include a first warning light 341, a second warning light 342, and a third warning light 343. As shown in Figure 2, the first warning light 341, the second warning light 342, and the third warning light 343 are respectively disposed on the left edge, the right edge, and the front edge of the rearview mirror B of the motorcycle M. The controller 32 controls the first warning light 341 according to the detection signals output by the detection devices 10, 10', 10'' installed on the baffles of the left side, the right side, and the front side of the motorcycle M. 41. The second warning light 342 and the third warning light 343 are activated. For example, when the detection radar 14 located on the left side of the motorcycle M detects that another vehicle or object is approaching the motorcycle M from the left side of the motorcycle M, the controller 32 controls the first warning light 341 to illuminate or flash according to the detection signal output by the detection radar 14 located on the left side of the motorcycle M. Thus, the driver can easily know that another vehicle or object is approaching the motorcycle M from the left side of the motorcycle M simply by looking at the rearview mirror B of the motorcycle M, from the location of the first warning light 341 (the left edge of the rearview mirror B). In this embodiment, the warning device 34 is described using multiple warning lights as an example. In other embodiments, one or more warning lights may be provided in conjunction with the number of detection devices 10.

[0018] Referring to Figure 1B, it is further explained that in this embodiment, the detection devices 10, 10' are respectively installed on the left and right sides of the motorcycle M near the rear side panel. Thus, when a vehicle M' approaches from the left or right rear, enters the detection range Z2, Z2' of the detection devices 10, 10', the detection radar 14 of the detection devices 10, 10' can detect that a vehicle M' is approaching the motorcycle M from the left or right rear side of the motorcycle M. When the vehicle M' leaves the detection range Z2, Z2', as shown in Figure 1B, the vehicle M' from the left or right enters the driver's horizontal field of view Z1, with an included angle of approximately 120 degrees.

[0019] In this embodiment, the warning device 34 further includes a buzzer. The controller 32 can receive the corresponding detection signals emitted by each of the detection radars 14 and control the buzzer to operate according to the corresponding detection signals emitted by each of the detection radars 14. For example, when the detection radar 14 detects that other vehicles or objects are approaching the motorcycle from the left side, right side or front side of the motorcycle M, the controller 32 controls the buzzer to sound to remind the driver that other vehicles or objects are approaching. At this time, the user can determine the direction of other vehicles or objects by looking at the rearview mirror of the motorcycle M to see if the first warning light 341, the second warning light 342 or the third warning light 343 is activated.

[0020] Alternatively, the controller 32 can also control the buzzer to emit a corresponding voice alarm based on the detection signals output by the detection devices 10 installed on the left side panel, right side panel, and front side panel of the motorcycle M. For example, when the detection radar 14 installed on the left side panel of the motorcycle M detects that another vehicle or object is approaching the motorcycle from the left side panel, the controller 32 controls the buzzer to emit a voice alarm indicating that another vehicle or object is approaching the motorcycle from the left side panel based on the detection signal output by the detection radar 14 installed on the left side panel of the motorcycle M. In this way, the user does not need to look at the rearview mirror of the motorcycle M; he / she can know the direction of other vehicles or objects by the content of the voice alarm.

[0021] As shown in Figure 6, each detection device 10 includes a first Bluetooth module 19 disposed in the housing 12. The first Bluetooth module 19 of each detection device 10 is connected to the detection radar 14 of the respective detection device 10. The warning module 30 includes a second Bluetooth module 36 and a GPS module 38. The controller 32 is connected to the second Bluetooth module 36 and the GPS module 38. The detection radar 14 of each detection device 10 emits the detection signal through the first Bluetooth module 19, and the controller 32 receives the first Bluetooth module 19 signal from each detection device 10 through the second Bluetooth module 36. The controller 32 controls the alarm 34 to operate based on the detection signal emitted by the first Bluetooth module 19 of each detection device 10 and the location signal output by the GPS module 38. The location signal includes the speed and coordinates of the motorcycle M. The controller 32 performs cross-sectional AI calculations based on the detection signal and the location signal to make subsequent decisions and control the alarm 34 to operate. Through the detection signal and the location signal, the relative speed and relative coordinates of the object detected by each detection radar 14 and the motorcycle M can be calculated more quickly, thereby improving the accuracy and timeliness of the warning.

[0022] Further explanation is provided that the first Bluetooth module 19 and the second Bluetooth module 36 can be connected to a mobile device P via a signal. When the power supply of the detection device 10 is low, the first Bluetooth module 19 sends a first low power warning message to the mobile device P. When the power supply of the warning module 30 is low, the second Bluetooth module 36 sends a second low power warning message to the mobile device P. For example, when the power supply of the detection device 10 is lower than 2.5V, the first Bluetooth module 19 will send the first low power warning message to the mobile device P. When the power supply of the warning module 30 is lower than 6V, the second Bluetooth module 36 will send the second low power warning message to the mobile device P, thereby reminding the user to replace the battery or charge it. The first Bluetooth module 19 and the second Bluetooth module 36 can be, for example, BT 5.0, BT 5.1, BT 5.2, BT 5.3 or BT 5.4 Bluetooth modules, but are not limited thereto.

[0023] To further explain, please refer to Figure 2. These warning lights include a distance warning light 344. The controller 32 determines the distance between the external object and each of the detection radars 14 based on the detection signals and the position signals, defining a first predetermined distance less than a second predetermined distance, and the second predetermined distance less than a third predetermined distance. When the distance is less than the first predetermined distance, the controller controls the distance warning light to emit a first color light; when the distance is between the first predetermined distance and the second predetermined distance, the controller 32 controls the distance warning light 344 to emit a second color light; when the distance is between the second predetermined distance and the third predetermined distance, the controller 32 controls the distance warning light 344 to emit a third color light. For example, the first... The first predetermined distance is 1 meter, the second predetermined distance is 2 meters, and the third predetermined distance is 6 meters. When each of the detection radars 14 detects another vehicle or object approaching the motorcycle M and the distance is less than 1 meter, the controller 32 controls the distance warning light 344 to emit a red light; when each of the detection radars 14 detects another vehicle or object approaching the motorcycle M and the distance is between 1 and 2 meters, the controller 32 controls the distance warning light 344 to emit an orange light; when each of the detection radars 14 detects another vehicle or object approaching the motorcycle M and the distance is between 2 and 6 meters, the controller 32 controls the distance warning light 344 to emit a yellow light. In this way, the driver can judge the distance by observing the different colored lights emitted by the distance warning light 344.

[0024] Further explanation is that the controller 32 can also determine the distance between the external object and the detection radar 14 based on the detection signal and the position signal, and control the buzzer to emit a corresponding alarm accordingly. For example, when the detection radar 14 detects that another vehicle or external object is approaching the motorcycle M and the distance is less than 1 meter, the controller 32 controls the buzzer to emit a continuous alarm sound for 3 seconds; when the detection radar 14 detects that another vehicle or external object is approaching the motorcycle M and the distance is between 1 and 2 meters, the controller 32 controls the buzzer to emit an alarm sound every 0.1 seconds and continue to operate for 2-3 seconds; when the detection radar 14 detects that another vehicle or external object is approaching the motorcycle M and the distance is between 2 and 6 meters, the controller 32 controls the buzzer to emit an alarm sound every 0.2 seconds and continue to operate for 1 second. In this way, the driver can judge the distance by the frequency of the alarm sound emitted by the buzzer.

[0025] Furthermore, in conjunction with Figures 7 and 8, when the GPS module 38 detects that the motorcycle's speed is below a predetermined speed (e.g., less than 25 km / hr); each of the detection radars 14 does not detect any foreign objects around the motorcycle M; and / or each of the detection radars 14 detects that the distance between the foreign objects around the motorcycle M and the motorcycle is greater than a predetermined distance, such as 10 meters, the controller 32 controls the detection distance of the internal loop scanning detection operation RF of each detection radar 14 to decrease, for example, to as low as 5 meters; and the controller 32 also controls the Serial Peripheral Interface Bus (SPI) to reduce the data transmission power, for example, to P5 / 2000 (duty cycle 5 / 2000us, at which time the power consumption can be as low as 2.3mW), P5 / 1000 (power consumption is 3.4mW), P5 / 1000 (power consumption is 5.6mW), P The P5 / 2000 is preferred, as it has a lower power consumption (10.3mW) and thus achieves power saving. Additionally, the controller 32 can control the transmission speed of the first Bluetooth module 19 to decrease from, for example, 2Mbps to, for example, 500Kbps or 125Kbps, thereby reducing the current (Tx Current) at the signal transmitter of the detection radar 14, or it can control it to enter a sleep state.

[0026] When the GPS module 38 detects that the vehicle speed is higher than or equal to the predetermined speed, or when each of the detection radars 14 detects that there are foreign objects around the vehicle M and the distance is less than or equal to, for example, 10M, the controller 32 further increases the RF power of the loop scanning of each of the detection radars 14 by 10M, the SPI data transmission speed and the transmission speed of the first Bluetooth module 19, thereby achieving the effect of saving power. In addition, each of the detection radars 14 is equipped with a vibration sensing circuit. If each detection radar 14 fails to detect the vibration of the locomotive M for more than, for example, 1 minute, the controller 32 can also control the detection distance of the loop scanning detection operation RF in each detection radar 14 to be reduced, for example, as low as 5M. The controller 32 will also control the Serial Peripheral Interface Bus (SPI) to reduce the data transmission power to, for example: P5 / 2000 (duty cycle 5 / 2000us, at which time the power consumption can be as low as 2.3mW), P5 / 1000 (power consumption is 3.4mW), P5 / 1000 (power consumption is 5.6mW), P5 / 250 (power consumption is 10.3mW), etc., preferably P5 / 2000, so as to achieve lower power consumption and achieve power saving effect. In addition, the controller 32 can also control the transmission speed of the first Bluetooth module 19 to be reduced from, for example, 2Mbps to, for example, 500Kbps or 125Kbps, thereby reducing the signal transmitter current (Tx Current) of the detection radar 14, or it can also control it to enter a sleep state to achieve the effect of saving power.

[0027] In summary, through the detection of each of the detection radars 14, when other vehicles or objects approach the motorcycle M, the controller 32 receives the detection signals emitted by each of the detection radars 14 and controls the warning device 34 to operate according to the detection signals. In this way, the motorcycle driver can be reminded in a timely and effective manner that other vehicles or objects are approaching the motorcycle, thereby achieving the effect of active safety warning. In addition, through the design of the housing 12 being detachably combined with the quick-release base 20, the user can quickly remove the detection device 10 or install it on the quick-release base 20 on the motorcycle M.
