Construction Method of the Helmet

[0050] FIG. 1 is a schematic representation of a protective helmet system 10 according to the exemplary embodiment of the present invention. The helmet system 10 comprises a helmet 20 and a remote control 180. The helmet 20 comprises an upper shell 31, a bottom shell 32, a harness 33, a LED strip 60, and an electronics and battery box 70, all of which are integrated with a liner 40 to form the helmet 20 as described in further detail as follows. The upper shell 31 and the bottom shell 32 are made of hard materials and are means for protecting a rider who wears the helmet 20. The harness 33 enables the helmet 20 to be fastened to the rider's head. The LED strip 60 is installed on the helmet 20, and has plural LEDs for producing light signals such that the rider becomes more visible to surrounding cars and pedestrians, thereby promoting safety to the rider. The electronics and battery box 70 is a place for housing (often visually-unbeautiful) electronics for operating the helmet 20 while maintaining a beautiful aesthetic outlook for the helmet 20. The upper shell 31 and the bottom shell 32 may be decorated to generate the beautiful aesthetic outlook.

[0051] Construction of the helmet 20 is explained as follows with the aid of FIGS. 2A-2C. FIG. 2A provides a perspective view of the helmet 20 while FIGS. 2B and 2C give two different exploded views thereof. The upper shell 31, the LED strip 60, the bottom shell 32 and the harness 33 are attached and integrated to the liner 40 so as to form the helmet 20. Preferably, the upper shell 31 and the bottom shell 32 are vacuum-formed with plastic. The liner 40 is also preferably made from high-density impact-absorption foam having multiple vent holes for ventilation, plural channels for embedding the LED strip 60, plural wells for housing the electronics and battery box 70, and holes for enabling the harness 33 to be fix therein.

[0052] The electronics and battery box 70 is also deemed a control module for the helmet 20. Hereinafter, the two terms the electronics and battery box and the control module are used interchangeably.

[0053] Furthermore, the liner 40 is configured to provide safety protection to a rider of the helmet system 10. When the rider is impacted on his or her head, the liner 40 will be deformed, thus absorbing the energy of impact to protect the rider's head.

[0054] FIG. 3 depicts a perspective exploded view of the electronics and battery box 70 of the helmet 20 according to one embodiment of the present invention. The electronics and battery box 70 comprises a bottom plastic housing 75 and an upper plastic housing 76 both configured to form an enclosure when the bottom plastic housing 75 is fitted to the upper plastic housing 76. The electronics and battery box 70 further comprises one or more proximity sensors 77, one or more speakers 78, one or more vibration motors 79 and one or more motion sensors 710. In one implementation, a PCB board 73 is also installed in the electronics and battery box 70. The electronics and battery box may also include a magnetic charging port 71. In addition, the electronics and battery box 70 is configured to house a battery 74.

[0055] FIGS. 4A, 4B and 4C depict different views of the LED strip 60 in accordance with one embodiment of the present invention. The LED strip 60 comprises a flexible base 68, and a plurality of LEDs installed on the flexible base 68. Preferably, the plurality of LEDs includes a front-right LED 62, a back-right LED 63, a back LED 64, a back-left LED 65, a front-left LED 66, a left brim LED 671, a right brim LED 672 and a center brim LED 673. In one preferred embodiment, each of the front-right LED 62 and the front-left LED 66 is preferably a super-bright dual-color orange and white LED; the back-right LED 63 and the back-left LED 65 are preferably super bright orange LEDs; the back LED 64 is preferably a super bright RED LED; the left brim LED 671 and the right brim LED 672 are preferably orange LEDs; the center brim LED 673 is red.

[0056] FIGS. 5A-5D depict perspective views regarding different versions of the remote control 180 according to one embodiment of the present invention. Refer to the two versions shown in FIGS. 5A and 5B first. The remote control 180 comprises a left button 51, a right button 52, an electronics box 50, and a mount 53 that is attached to a handle bar of the bicycle (or a handle bar of any vehicle that the rider rides on). The left button 51 and right button 52 are preferably made of soft rubber plastic. It is also preferable that the casing is plastic. Preferably, the mount 53 is plastic. In each of the versions shown in FIGS. 5A and 5B, the left button 51 and the right button 52 are positioned on or over the mount 53. In FIGS. 5C and 5D, there are two other versions each of which has a mount 54 having two wired buttons as a left button and a right button.

[0057] The LED strip 60 is controlled by the control module 70. In the normal time when the rider is biking straight, the control module 70 will signal the LED strip 60 so that the back LED 64 is blinking. In this way, the rider will become more visible to surrounding cars and pedestrians.

[0058] The control module 70 also is configured with the Bluetooth connectivity for communicating with an external Bluetooth-enabled device in one embodiment. In one mode of operation, the control module 70 can connect to a smartphone, and communicate with a designate smartphone application through Bluetooth. The control module 70 can transmit the information about the battery 74 to the smartphone so that the remaining energy on the battery 74 can be displayed. The rider can also designate blinking patterns for the LED strip 60 under different situations. When the control module 70 detects occurrence of high impact on the helmet 20 through the one or more motion sensors 710, the control module 70 can also transmit signal to the smartphone to trigger emergency call or messaging function on the smartphone.

[0059] FIGS. 6 and 7 are two flowcharts showing examples of firmware programs implemented in the control module 70 and in the remote control 180, respectively.

[0060] Note that it is required to install electronics into the helmet 20 to provide functions thereto. In this regard, one or more electronic boxes, including the electronics and battery box 70, are included in the helmet 20. Advantageously, each electronic box may be designed with a further objective of providing protection to the rider against being impacted by electronic components in the electronic box in case of an accident.

[0061] FIGS. 8A, 8B and 8C depict a perspective exploded view, a bottom cross-section view and a side cross-section view, respectively, of a helmet with an electronics box having a wing design in accordance with one embodiment of the present invention. In particular, FIGS. 8A, 8B and 8C illustrate a method of integrating electronics into a helmet 82 with an electronics box 200 that features the wing design. In these figures, a cover 80 of the electronics box 200, a bottom 81 of the electronics box 200, the helmet 82 that the electronics are integrated in, and an exemplary PCB 83 that represents the electronics are shown. How this design enables the integration of electronics into the helmet 82 is through the following two ways.

[0062] First, a wing 91 protrudes from the cover 80 that extends the contact of the electronics box 200 to the surrounding helmet section of the helmet 82. During impact, the surrounding area absorbs the impact energy.

[0063] Second, a cavity 92 is situated between the bottom 81 of the electronics box 200 and the helmet 82. This cavity 92 prevents the compression of the foam of the helmet 82 beneath the electronics box 200 at the early stage of impact. During impact, the wing 91 transfers the impact energy to the area beneath the wing 91 first as the foam at this area collapse, this cavity 92 shrinks to a point that the foam beneath the bottom 81 of the electronics box 200 also starts to collapse and thus absorbs energy. If this cavity 92 were not there, the impact energy would pass to the foam beneath the bottom 81 of the electronics box 200 at the very first beginning of impact. Thus, more energy will be passed to this area where the foam is thinner because of the existence of the electronics box 200. This cavity 92 thus acts as a buffer to let the foam that surrounds the electronics box 200, which is thicker, absorb the energy first, thus decreasing the energy that the foam beneath the electronics box 200 need to absorb, and passing less energy to the head of the rider.

Operation Method

[0064] There are several events that can trigger a change of the light pattern of the LED strip 60. [0065] 1. In one event that the rider is slowing down, the one or more motion sensors in the electronics and battery box 70 will sense the deceleration of the bike, and then changes the LED pattern such that the back left LED 65, the back LED 64, the back right LED 63 are kept on until the bicycle comes to a stop. [0066] 2. In another event that the rider presses the left button 51 on the remote control 180 to signal to the surrounding that it is turning left, the back LED 64, the left brim LED 671, the front-left LED 66 and the back-left LED 65 keep blinking. [0067] 3. In another event when the rider presses the right button 52 on the remote control 180 to signal to the surrounding that it is turning right, the back LED 64, the right brim LED 672, the front-right LED 66 and the back-right LED 65 keep blinking. [0068] 4. In the event when the control module 70 detects an approaching vehicle via the one or more proximity sensors 77, the control module 70 will control the center brim LED 66 to blink and increase the brightness of the LED strip 60. The control module 70 will also trigger the one or more vibration motors 79 to vibrate and the one or more speakers 78 to emit alarming sound thus to notify the rider.

[0069] While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
