Description

Technical Field

[0001] The present application relates to the technical field of cycling safety protection, and in particular to a smart helmet. Background Art

[0002] Helmets are required when driving electric vehicles and motorcycles. They are head protection and an indispensable tool in transportation. Research has shown that properly wearing a helmet and using seatbelts can significantly reduce the incidence of life-threatening traffic accidents. This is because helmets absorb much of the impact force during an accident, providing cushioning and shock absorption. Therefore, helmets play a crucial role in protecting people's lives.

[0003] However, existing helmet designs are relatively simple in function and fail to meet people's needs. For example, bus and truck drivers have multiple blind spots when driving, and when a truck turns, there are large blind spots on both sides of the wheels. Street surveys have found that cyclists need to turn their necks or bodies to understand road conditions during riding. Even if cyclists wear safety helmets, this method still carries a high risk because cyclists have blind spots and many cyclists turn their bodies to observe while riding. Therefore, even if a helmet is worn according to standard requirements, safety risks still exist. Utility Model Content

[0039] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.

[0040] Before describing the smart helmet provided by the embodiment of the present application, the implementation background of the embodiment of the present application will be explained first. As we all know, a helmet is a piece of equipment used to protect the head and is also an indispensable tool in traffic. Relevant research shows that correctly wearing a safety helmet and using a seat belt in a standardized manner can significantly reduce the incidence of life-threatening traffic accidents. Because when an accident occurs, the helmet can absorb most of the impact force and play a protective role in buffering and shock absorption. Therefore, helmets play an important role in protecting people's lives. During riding, the rider needs to turn his neck or body to know the road conditions during riding. Although the rider wears a safety helmet, this method still has a high risk because the rider himself has a blind spot in his field of vision, and many riders turn their bodies to observe while riding. Therefore, even if the helmet is worn according to the standard, there are still safety hazards.

[0041] Based on this, an embodiment of the present application provides a smart helmet. The smart helmet can use a first sensor mounted on a first mounting base on the left side of the helmet body to collect a first signal within a first preset distance range in a first quadrant (left rear direction) and transmit the first signal to a display device mounted on a second mounting base on the front side of the helmet body. A second sensor mounted on the first mounting base on the right side of the helmet body can also use a second sensor mounted on the first mounting base on the right side of the helmet body to collect a second signal within a second preset distance range in a second quadrant (right rear direction) and transmit the second signal to the display device. Prior to receiving the first and second signals, the display device displays a first image. Upon receiving the first signal, a first controller controls the left display area of ​​the display device to switch from the first image to the second image. Upon receiving the second signal, the first controller controls the right display area of ​​the display device to switch from the first image to a third image. Therefore, the smart helmet of the embodiment of the present application can use the first and second sensors to collect signals when a vehicle is within a preset distance to the left and right rear of the wearer of the smart helmet, and transmit the signals to a display device on the front side of the smart helmet. Furthermore, the display device can display different images depending on the direction of signal transmission, thereby enabling the rider wearing the helmet to be informed of road conditions behind them and receive timely alerts.

[0042] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0043] This application embodiment provides a smart helmet, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 This is a first structural diagram of the smart helmet provided in an embodiment of the present application; Figure 2 2 is a schematic left view of a second structure of the smart helmet provided in an embodiment of the present application; Figure 32 is a schematic right view of a third structure of the smart helmet provided in an embodiment of the present application; Figure 4 This is a schematic rear view of the fourth structure of the smart helmet provided in an embodiment of the present application.

[0044] In the examples of this application, please see Figure 1 The smart helmet includes a helmet body 10, a detection device, and a display device 20. First mounting bases 101 are provided on the left and right sides of the helmet body, respectively, based on the left and right sides of the wearer. The detection device is mounted on the helmet body 10 via the first mounting bases 101. A second mounting base 102 is provided on the front side of the helmet body 10. The display device 20 is mounted on the helmet body 10 via the second mounting base 102.

[0045] See Figure 2 、 Figure 3 and Figure 4 The second mounting base 102 includes: a first clamping arm 1021 and a second clamping arm 1022. The first clamping arm 1021 has one end mounted on the front side of the helmet body 10 and the other end extending away from the front side of the helmet body 10 and having a first bent portion 1021-1 at the end. The second clamping arm 1022 is located on both sides of the first clamping arm 1021 and extends from the middle area of ​​both sides of the first clamping arm 1021 in a direction away from the first clamping arm 1021. The ends of the second clamping arms 1022 are respectively provided with a second bent portion 1022-1. The display device 20 is fixed to the second mounting base 102 via the first bent portion 1021-1 and the second bent portion 1022-1. The first clamping arm 1021 and the second clamping arm 1022 are integrally structured. The first bent portion 1021-1 bends downward perpendicularly to the first clamping arm 1021, and the second bent portion 1022-1 bends downward perpendicularly to the second clamping arm 1022.

[0046] Taking into account the instability during the wearing of the helmet, which may easily cause the display device to shake, a plurality of mounting holes are provided on the first bending portion in the embodiment of the present application. The display device is mounted on the first bending portion through the cooperation between the fixing part and the mounting hole, thereby achieving the fixation of the display device in the vertical direction, and the display device is fixed in the horizontal direction through the two second bending portions at the end of the second clamp arm.

[0047] In an embodiment of the present application, the detection device includes a first sensor and a second sensor, wherein the first sensor is mounted on a first mounting base 101 on the left side of the helmet body 10, and the second sensor is mounted on a first mounting base 101 on the right side of the helmet body 10. In a specific implementation, the first sensor collects a first signal within a first quadrant and within a first preset distance range, and sends the first signal to the display device 20, and the display device 20 switches the display mode according to the received first signal, wherein the first quadrant and the second quadrant are determined with the driving direction as the opposite direction of the Y axis, and the first quadrant can specifically be the left rear area of ​​the wearer of the smart helmet. The second sensor collects a second signal within a second quadrant and within a second preset distance range, and sends the second signal to the display device, and the display device switches the display mode according to the received second signal, wherein the second quadrant can specifically be the right rear area of ​​the wearer of the smart helmet, and the first sensor and the second sensor can specifically be ultrasonic sensors.

[0048] It should be noted that the first sensor is mounted on the first mounting base on the left side of the helmet body, and the second sensor is mounted on the first mounting base on the right side of the helmet body because, during riding, the rider needs to turn his neck or body to understand the road conditions during riding. Although the rider wears a safety helmet, this method still carries a high risk because the rider has blind spots, and many riders turn their bodies to observe while riding, which still poses a safety hazard. Therefore, the first sensor can collect signals when a vehicle is within a preset distance to the left and right rear of the smart helmet wearer, and transmit the signals to the display device at the front of the smart helmet. The second sensor can collect signals when a vehicle is within a preset distance to the right rear of the smart helmet wearer, and transmit the signals to the display device at the front of the smart helmet. The display device can display different images according to the different signal transmission directions, so that the rider can understand the road conditions during riding without turning his neck or body, thereby ensuring riding safety.

[0049] In an embodiment of the present application, the display device 20 includes a left display area and a right display area. Before receiving the first signal and the second signal, the display device 20 displays a first picture; when receiving the first signal, the first controller controls the left display area to switch from the first picture to the second picture; and / or, when receiving the second signal, the first controller controls the right display area to switch from the first picture to the third picture.

[0050] It should be noted that the display device is used to display the situation of vehicles coming from behind the wearer of the smart helmet. The display device is located on the front side of the helmet body and has a preset distance from the helmet body. Before the display device receives the first signal and the second signal, that is, when there is no vehicle within the preset distance behind the wearer of the smart helmet, the display device continues to display the first picture until a vehicle appears. For example, the first picture can be a "smiling face"; when the first sensor detects that there is a vehicle within a first preset distance behind the left of the smart helmet wearer, the first signal is transmitted to the display device. After receiving the signal, the display device switches from "smiling face" to full brightness of the left half. The smart helmet wearer can know from the picture that a vehicle is approaching from the left rear, and thus avoid it in time; when the second sensor detects that there is a vehicle within a second preset distance behind the right of the smart helmet wearer, the second signal is transmitted to the display device. After receiving the signal, the display device switches from "smiling face" to full brightness of the right half. The smart helmet wearer can know from the picture that a vehicle is approaching from the right rear, and thus avoid it in time; when the first sensor detects that there is a vehicle within the first preset distance behind the left of the smart helmet wearer, and the second sensor detects that there is a vehicle within the second preset distance behind the right of the smart helmet wearer, the first signal and the second signal are transmitted to the display device. After receiving the signal, the display device switches from "smiling face" to full brightness of both sides. The smart helmet wearer can know from the picture that there are vehicles approaching from both the left and right rear, and thus avoid it in time.

[0051] In a specific implementation, any image on the display device can be displayed for one second or a predetermined duration. After one second or the predetermined duration, the first and second sensors re-collect signals, and the display device displays the corresponding image based on the re-collected signals. By cooperating with the first and second sensors to display different images, the display device allows helmeted cyclists to be informed of road conditions behind them and receive timely alerts, effectively reducing the probability of accidents.

[0052] It should be noted that the specific display method of the display device is achieved through programming. In the embodiment of the present application, taking the display device as an expression panel as an example, when the first sensor collects the first signal within a predetermined distance, the left half of the expression panel lights up, when the second sensor collects the second signal within the predetermined distance, the right half of the expression panel lights up, when the first sensor collects the first signal within the predetermined distance, and when the second sensor collects the second signal within the predetermined distance, the expression panel lights up completely, and the panel goes out after 1 second or a predetermined time.

[0053] In this application, please refer to Figure 3A third mounting base 103 is provided on the outer side of the top of the helmet body 10. The detection device also includes a third sensor, which is mounted on the third mounting base 103. A fourth mounting base 104 is also provided on the outer side of the rear end of the helmet body 10. Light-emitting devices are mounted on the fourth mounting base 104. The light-emitting devices include a first light-emitting device, a second light-emitting device, a third light-emitting device, and a fourth light-emitting device. The light-emitting devices can specifically be LED lamps. The third sensor collects light signals and sends the light signals to the second controller. The second controller controls the light-emitting devices to switch light-emitting modes according to the light signals.

[0054] It should be noted that the third sensor is a light sensor, which is used to collect light signals for the purpose of detecting whether it is dark. When it is dark, the LED light will flash, and the second controller will control the light-emitting device to emit light in different light-emitting modes according to the light signal. When the light signal is within the first threshold range, for example, when the first threshold range is 410-450 candela, the second controller controls the light-emitting device to switch to the first light-emitting frequency mode, and in the first light-emitting frequency mode, the LED light will flash faster; when the light signal is within the second threshold range, for example, when the second threshold range is 390-410 candela, the second controller controls the light-emitting device to switch to the second light-emitting frequency mode, and in the second light-emitting frequency mode, the second controller controls the light-emitting device to adopt a combination of single flashing and full flashing, so as to remind the following vehicle to keep a safe distance, effectively reduce the risk of vehicle collision at night, and ensure safety. The above threshold range can be adjusted according to the driving environment, weather conditions, season, etc., and is not limited to the example values ​​given in the above example.

[0055] In a specific implementation, when the light signal is within the first threshold range, the second controller controls the first, second, third, and fourth light-emitting devices to trigger a first light color mode under the first light frequency mode. Triggering the first light color mode under the first light frequency mode includes: the second controller controls one or more of the first, second, third, and fourth light-emitting devices to switch between the first preset light color and the second preset light color according to a first preset light color corresponding to a first preset time and a second preset light color corresponding to a second preset time under the first light frequency mode. The second controller controls the first and third light-emitting devices to switch from the first light color mode to the third light color mode, and controls the second and fourth light-emitting devices to switch from the first light color mode to the fourth light color mode, based on a received trigger signal for triggering the third light color mode.

[0056] It should be noted that contrasting colors typically have significant color differences. To make the light-emitting devices' colors more eye-catching, the light-emitting devices flash rapidly according to the contrasting colors. "Yellow-red-blue" and "orange-purple-green" are the most typical contrasting colors. Yellow and red are both warm colors and share a common color (orange) on the color wheel. Yellow has a high brightness, while red has a low brightness. Therefore, the red and yellow color combination is both harmonious and creates a strong sense of contrast. Therefore, when the light signal is within the first threshold range, the second controller controls the first, second, third, and fourth light-emitting devices to trigger a first light color mode in the first light frequency mode. In the first light color mode, for example, if the light intensity signal detected by the light sensor is less than 450 candela, one or more of the light-emitting devices flash rapidly, displaying a yellow light for, for example, 0.1 second and a red light for, for example, 0.12 seconds, for a duration of, for example, 3 seconds. After the flashing is completed, the first light emitting device and the third light emitting device switch from the above-mentioned fast flash mode (first light color mode) to flashing only red light (third light color mode), and the flashing time interval is, for example, 0.3 seconds. For example, after 1 second, the second light emitting device and the fourth light emitting device simultaneously display yellow light (fourth light color mode). The light color mode of the above-mentioned light emitting devices is more eye-catching, thereby reminding the following vehicle to keep a safe distance.

[0057] In a specific implementation, when the light signal is within the second threshold range, the second controller controls the first, second, third, and fourth light-emitting devices to trigger a second light color mode in the second light frequency mode. Triggering the second light color mode in the second light frequency mode includes: the second controller controls one or more of the first, second, third, and fourth light-emitting devices to switch between a preset fixed light color and a random light color in the second light frequency mode. The second controller controls one or more of the first, second, third, and fourth light-emitting devices to switch from the second light color mode to the fifth light color mode in response to a received trigger signal for triggering the fifth light color mode.

[0058] It should be noted that when the light signal is within the second threshold range, the second controller controls the first, second, third, and fourth light-emitting devices to trigger a second light color pattern in the second light frequency mode. In the second light color pattern, the second controller controls one or more of the first, second, third, and fourth light-emitting devices to switch between a preset fixed light color and a random light color in the second light frequency mode. At the end of the pattern, the second controller controls one or more of the light-emitting devices to flash rapidly, for example, orange for 0.1 seconds and green for 0.1 seconds, for a duration of, for example, 5 seconds (15 times).

[0059] In a specific implementation, the second controller controls one or more of the first, second, third, and fourth light-emitting devices to switch from the third and fourth light-emitting color modes to the sixth light-emitting color mode, or to switch from the fifth light-emitting color mode to the sixth light-emitting color mode, based on a received trigger signal for triggering the sixth light-emitting color mode. It should be noted that after all flashes are completed, the second controller controls one or more of the light-emitting devices to execute the sixth light-emitting color mode, which continuously and rapidly flashes 10 colors. The 10 colors are numbered 19CAAD, 8CC7B5, A0EEE1, BEE7E9, BEEDC7, D6D5B7, D1BA74, E6CEAC, ECAD9E, and F4606C. The R (red) / G (green) / B (blue) ratios of the 10 colors are 25 / 202 / 173, 140 / 199 / 181, 160 / 238 / 225, 190 / 231 / 233, 190 / 237 / 199, 214 / 213 / 183, 209 / 186 / 116, 230 / 206 / 172, 236 / 173 / 158, and 224 / 96 / 108, respectively. In the sixth color mode, the 10 colors light up in a preset order, with an interval of, for example, 0.3-0.8 seconds.

[0060] In an embodiment of the present application, a radiator is further provided at the rear of the display device. Of course, the radiator can also be provided on the left and right sides of the front bottom of the helmet body, or radiators can be provided at the rear of the display device and on both the left and right sides of the front bottom of the helmet body. The radiator can specifically be a fan, and the size of the fan can be specifically designed to match the size of the smart helmet. The radiator is mounted on the second mounting base via a flexible connector, or is mounted on the left and right sides of the front bottom of the helmet body via the flexible connector; the working angle of the radiator is set by adjusting the curvature of the flexible connector. By providing a flexible connector, the angle of the fan can be adjusted, thereby better providing cooling service for the rider.

[0061] In an embodiment of the present application, the detection device further includes a fourth sensor disposed within the helmet body; the fourth sensor collects a temperature signal from the interior of the smart helmet and triggers the start and stop of the radiator based on the temperature signal. It should be noted that when the temperature signal collected by the fourth sensor exceeds a preset temperature threshold range, the radiator is triggered to start until the temperature inside the smart helmet falls below the preset threshold range. When the temperature signal collected by the fourth sensor falls below the preset temperature threshold range, the radiator is triggered to stop, thereby ensuring that the interior of the smart helmet remains at a comfortable temperature.

[0062] It should be noted that the fourth sensor is a temperature sensor, which is used to detect the temperature inside the smart helmet. According to information found online, the temperature range for people to feel comfortable is 25-26°C. If the temperature range is 27-30°C, it will feel uncomfortable and hot; if the temperature range is 30-33°C, it will feel very hot; if the temperature range is 33-35°C, it will feel very hot and need to shower promptly; if the temperature range is 35-37°C, it will feel too hot and need to shower frequently; if the temperature is >37°C, it will feel extremely hot and very prone to heatstroke. By setting this temperature sensor, the current temperature inside the smart helmet can be effectively detected. In this embodiment of the application, the preset temperature threshold range is set to 30-32°C. When the temperature signal inside the smart helmet collected by the fourth sensor indicates that the temperature exceeds 30-32°C, the radiator fan will rotate at full speed until it drops below 30-32°C. The cooperation between the temperature sensor and the radiator fan effectively solves the discomfort felt by riders when riding in hot weather.

[0063] In an embodiment of the present application, a fifth sensor and a voice alarm are also installed on the third mounting base; the fifth sensor is a speed sensor, which collects the speed signal of the wearer wearing the smart helmet when riding, and sends the speed signal to a third controller, and the third controller controls the start and stop of the voice alarm according to the speed signal; when the speed signal exceeds a third threshold range, the third controller controls the voice alarm to switch to an alarm mode.

[0064] The above is the specific content of the smart helmet provided by the embodiment of the present application.
