Detailed Description

The following detailed description of the embodiments of the disclosure refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, without being described to the contrary, the terms of orientation such as "front and back" are used to refer to that the part of the helmet body near the face of the user is the front part and the part of the helmet body near the back brain of the user is the back part when the user wears the helmet, and refer to fig. 6 specifically. Use of directional words such as "inner and outer" refers to the inner and outer of the contours of a particular structure. The terms "first direction" and "second direction" used herein refer to a direction from the face of the user to the hindbrain of the user (or from the hindbrain of the user to the face of the user) as a first direction and a direction from the left ear to the right ear (or from the right ear to the left ear) as a second direction when the user wears the helmet, and refer to fig. 4 specifically. Furthermore, the use of terms such as "first" and "second" is intended only to distinguish one element from another, and is not intended to be sequential or important. Additionally, the directional terms used above are used merely to facilitate describing the disclosure and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and should not be construed as limiting the disclosure.

As shown in fig. 1 to 7, the present disclosure provides a helmet, this helmet includes helmet body 1, host system 2, detection electrode 3 and electric capacity detection module 7, helmet body 1 includes the helmet body 11 and sets up in the shell 12 in the helmet body 11 outside, host system 2 sets up on helmet body 1, detection electrode 3 hides between shell 12 and the helmet body 11, electric capacity detection module 7's signal input part is connected with detection electrode 3 electricity, electric capacity detection module 7's signal output part is connected with host system 2 electricity, electric capacity detection module 7 is used for detecting detection electrode 3's the electric capacity change condition.

Through the technical scheme, the detection electrode 3 is arranged and hidden between the shell 12 and the helmet body 11, and a user cannot judge the specific position of the detection electrode 3 in appearance, so that the problem that the detection error of the capacitance detection module 7 is caused by the fact that the user pastes foreign matters can be avoided. After the user wore the helmet, the electric capacity on the detection electrode 3 changes, electric capacity detection module 7 can transmit the electric capacity change condition on the detection electrode 3 for host system 2, host system 2 can acquire the data that the user that electric capacity detection module gathered wore the helmet production, this data can supply the server to carry out the analysis to the action of wearing the helmet of user, judge whether the user takes the helmet, thereby be favorable to monitoring and managing the action of wearing the helmet to the user.

It can be seen that, in the helmet provided by the present disclosure, the detection electrode 3 and the capacitance detection module 7 are disposed, which is not only beneficial to determining whether a user wears the helmet. Moreover, since the detecting electrode 3 is disposed and hidden between the shell 12 and the helmet body 11, the user cannot determine the exact position of the detecting electrode 3, and the detection of the capacitance detecting module 7 cannot be disturbed by means of sticking a foreign object. Therefore, when the main control module 2 detects that the capacitance data changes correspondingly, it indicates that the user has worn the helmet.

In addition, the method for detecting the capacitance is adopted in the disclosure, when a user wears the helmet, the head of the user enters the detection range of the detection electrode 3, corresponding capacitance change is generated on the detection electrode 3, and the capacitance detection module 7 transmits the capacitance change data to the main control module 2, so that whether the user wears the helmet can be detected. Compared with the conventional detection modes of temperature sensors, infrared sensors and the like through identifying temperature or light change, the capacitance detection mode adopted by the method is not easily interfered by factors such as light, temperature and the like, and has stronger anti-interference capability, so that the detection effect is more accurate.

Here, the above-mentioned "the detection electrode 3 is hidden between the outer shell 12 and the helmet body 11" means that the detection electrode 3 is hidden between the outer shell and the helmet body when the helmet body 1 has no hollow structure, or the position where the detection electrode 3 is provided is not located at the position where the hollow structure is located when the hollow structure is partially provided on the helmet body 1. That is, the mounting position of the detection electrode 3 cannot be found under the user's intuitive observation.

In addition, the specific structures of the detection electrode 3 and the capacitance detection module 7 are not limited in this disclosure, as long as the capacitance detection module 7 can transmit the capacitance change condition to the main control module 2 as long as the capacitance change can be generated on the detection electrode 3 after the helmet is worn by the user. For example, in an embodiment of the present disclosure, the detection electrode 3 may be provided as two oppositely disposed electrode plates, the two electrode plates are both installed between the shell 12 and the helmet body 11 along the front-back direction of the helmet body 1, after a user wears the helmet, the head of the user enters between the two electrode plates, the capacitance on the electrode plates changes, that is, the capacitance on the detection electrode 3 changes, the capacitance detection module 7 transmits the detected capacitance change data to the main control module 2, and the main control module 2 determines whether the user wears the helmet according to the capacitance change.

Optionally, as shown in fig. 2 to 6, in another embodiment of the present disclosure, the capacitance detection module 7 may include a Specific Absorption Rate (SAR) sensor, a signal input end of the SAR sensor is electrically connected to the detection electrode 3, an output end of the SAR sensor is electrically connected to the main control module 2, and the main control module 2 is configured to determine whether the user wears the helmet according to capacitance change data detected by the SAR sensor.

In this embodiment, after the user wears the helmet, the head of the user and the detection electrode 3 form an equivalent capacitor, when the head of the user enters the helmet and is close to the detection electrode 3, the capacitance value on the detection electrode 3 changes, the SAR sensor outputs the obtained variation of the capacitance value to the main control module 2, the main control module 2 determines the distance between the human body and the detection electrode 3 according to the variation of the capacitance value, the user recognizes that the helmet is worn when the distance is within a preset distance, and the user recognizes that the helmet is not worn when the distance is outside the preset distance.

It can be seen that, the detection electrode 3 is arranged between the shell 12 and the helmet body 11, and then the capacitance change value on the detection electrode 3 is identified by using the SAR sensor, so that the detection of whether the user wears the helmet or not can be realized on the basis of hiding the detection electrode 3. And, because the SAR sensor has the performance of quick identification, the time consumption of the detection process can be reduced.

Furthermore, the SAR sensor only needs to be electrically connected to a single detection electrode 3 in order to detect a change in capacitance on that detection electrode 3. Therefore, the helmet wearing detection can be completed only by arranging a single detection electrode 3 between the shell 12 and the helmet body 11, and two opposite electrode plates are not necessarily required to be arranged. Under the condition that only set up single detecting electrode 3, detecting electrode 3 is the installation space minimizing in helmet body 1, only need in helmet body 1 reserve a less installation space can, consequently, can be so that can reduce to minimum owing to installation detecting electrode 3 and to the influence that helmet body 1's security performance produced. Compared with a mode that two detection polar plates need to be installed, the helmet body 1 in the embodiment has better safety performance. In addition, single detecting electrode 3 can be in the regional nimble installation between shell 12 and the helmet body 11 for the user is difficult to distinguish detecting electrode 3's specific mounted position more, thereby has increased the degree of difficulty that the user sheltered from detecting electrode 3, avoids appearing the user and knows detecting electrode 3's specific mounted position and shelter from in order to avoid wearing the condition that the helmet detected intentionally.

Alternatively, as shown in fig. 2 and 4, the detection electrode 3 of the present disclosure may be provided in plurality, and the plurality of detection electrodes 3 are distributed dispersedly and electrically connected to the capacitance detection module 7, respectively. A plurality of detecting electrode 3 all can play the effect whether the head of detection user gets into the helmet alone, and a plurality of detecting electrode 3 can verify the accuracy in order to guarantee the testing result each other, consequently, set up a plurality of detecting electrode 3 and can reach the effect that improves the detection accuracy. Moreover, the distributed distribution of the plurality of detection electrodes 3 also increases the difficulty of intentionally shielding the detection electrodes 3 by a user, because the user is not likely to shield all the detection electrodes 3.

The present disclosure does not specifically limit the mounting positions of the plurality of detection electrodes 3. Optionally, in an embodiment, the plurality of detection electrodes 3 may be respectively installed at the front portion, the middle portion, and the rear portion of the helmet body 1, the capacitance detection module 7 respectively detects capacitance changes on all the detection electrodes 3, and the main control module 2 analyzes data of the detected capacitance changes to determine whether the user wears the helmet. And since the SAR sensor can detect capacitance change on the detection electrode 3 with any shape and length, the detection electrode 3 in the present disclosure can be set with any shape and length, which is not specifically limited in the present disclosure.

Alternatively, as shown in fig. 2 and 4, in one embodiment, each detection electrode 3 is configured to extend along a first direction, i.e., the detection electrode 3 may be configured as an elongated structure extending along the first direction, and a plurality of detection electrodes 3 are arranged at intervals along a second direction perpendicular to the first direction. Here, the plurality of detection electrodes 3 are arranged in the first direction a1 and provided on the helmet body 1 in a spaced arrangement. Like this, be favorable to making the detection range cover whole helmet body 1 to realize that a plurality of detecting electrode 3 detect simultaneously, a plurality of detecting electrode 3 can verify each other with the accuracy of guaranteeing the testing result. And the detection range covers the whole helmet body 1, so that the difficulty of shielding the detection electrode 3 by a user to avoid supervision can be further increased, and the detection result is more accurate.

Further, in the above-described embodiment, the plurality of detection electrodes 3 may be arranged at regular intervals in the second direction perpendicular to the first direction, so that the detection electrodes 3 are distributed more uniformly. The detection electrodes 3 on a certain part of the helmet body 1 are prevented from being mounted too much to generate mutual interference, so that the accuracy of a detection result is ensured. The detection electrode 3 on a certain part of the helmet body 1 can be prevented from being mounted too much, and the safety performance of the helmet body 1 is greatly influenced.

The present disclosure does not limit the specific shape of the detection electrode 3. Alternatively, as shown in fig. 2 and 4, in one embodiment, the detection electrode 3 may include one or more of a copper wire, an aluminum wire, an iron wire, and a silver wire. That is, the detecting electrode 3 is configured as a rod antenna, and when the detecting electrode 3 is plural, the plural detecting electrodes 3 may include wires of the same material or wires of different materials. Since the SAR sensor has low requirements on the detection electrode 3 and can complete detection by using a common lead, the detection electrode 3 of the present disclosure can be achieved by using a common lead. The copper wire is low in price and easy to obtain materials, so that the manufacturing cost and the manufacturing time can be reduced by using the copper wire.

As shown in fig. 2 and 4, the detection electrodes 3 in a wire shape may be arranged in the front-rear direction.

Alternatively, as shown in fig. 5 and 6, in another embodiment of the present disclosure, the detection electrode 3 may include an onboard antenna 4 disposed on the main control module 2, i.e., the detection electrode 3 includes a detection electrode integrated onto the main control module 2. At this moment, can be with on the board carries the antenna together integrated to electric capacity detection module 7, so, board carries antenna 4 and directly transmits for host system 2 through electric capacity detection module 7 with the electric capacity change on board carries antenna 4, need not additionally to lay wire on helmet body 1, can reach practice thrift the wiring cost and weaken because of the effect that the wiring weakens to helmet body 1 protective capacities.

In this embodiment, after the user wears the helmet, the user's head gets into helmet body 1 and is close to on-board antenna 4, and on-board antenna 4 produces corresponding capacitance change, and capacitance detection module 7 transmits this capacitance change data for main control module 2, and main control module 2 judges whether the user wears the helmet according to the capacitance change data. The number and the arrangement position of the on-board antennas 4 are not limited in the present disclosure, and may be any suitable number, may be arranged at any suitable position, and for example, may be provided in plural and distributed at intervals like the detection electrodes of the rod antennas in fig. 2 and 4.

It is understood that the detecting electrode 3 provided on the helmet body 1 may include only the detecting electrode 3 which is a rod antenna, or only the on-board antenna 4, or may include both the detecting electrode 3 which is a rod antenna and the on-board antenna 4 as shown in fig. 5 and 6.

Alternatively, as shown in fig. 2 and 3, in an embodiment of the present disclosure, the shell 12 covers an outer surface of the helmet body 11, and a first receiving cavity for receiving the detection electrode 3 is formed between the shell 12 and the helmet body 11. That is, in the present embodiment, the inner surface of the outer shell 12 and the outer surface of the helmet body 11 except the position of the first accommodating cavity can be attached to each other, which is beneficial to making the structure of the helmet body 1 more compact and reducing the volume of the helmet, and the surface of the inner surface of the outer shell 12 attached to the outer surface of the helmet body 11 is increased, which is beneficial to enhancing the structural strength of the helmet.

In the disclosure, the first receiving chamber has various structural forms. Alternatively, in an embodiment of the present disclosure, as shown in fig. 3, a first recess 5 may be provided on a surface of the helmet body 11 facing the shell 12, the first recess 5 and the surface of the shell 12 facing the helmet body 11 together defining a first receiving cavity. In the present embodiment, the first accommodation chamber is formed by the outer shell 12 and the helmet body 11. The required formation space on the housing 12 is small and does not result in a certain protrusion on the housing 12. The specific installation position of the detection electrode 3 cannot be distinguished from the appearance, and the hiding effect of the installation position of the detection electrode 3 can be realized on the basis of ensuring the installation of the detection electrode 3. In addition, the required arrangement space on the helmet body 11 is smaller, the structural influence on the helmet body 11 due to the arrangement of the first accommodating cavity can be reduced, the structure of the helmet body 1 can be more compact, and the structural strength of the helmet body 1 can be enhanced.

Alternatively, in another embodiment of the present disclosure, a side of the shell 12 facing the helmet body 11 may be provided with a groove, and the groove may define the above-mentioned first receiving cavity together with a surface of the helmet body 11 facing the shell 12. The arrangement of the groove on the shell 12 does not structurally affect the helmet body 11, and the protection performance of the helmet body 1 can be guaranteed to be unaffected. In addition, in still another embodiment of the present disclosure, a groove may be provided on a surface of the helmet body 11 facing the shell 12, and a groove may also be provided on a side of the shell 12 facing the helmet body 11, and the first receiving cavity may be enclosed by the two grooves.

Further, it should be noted that, in other embodiments of the present disclosure, the middle portions of both the outer shell 12 and the helmet body 11 are not in contact, and the connecting portion is provided only at the edge portion, so that the detection electrode 3 can be arranged with the use of the space between the inner surface of the outer shell 12 and the outer surface of the helmet body 11.

As shown in fig. 2 and 4, when the detection electrode 3 is a rod antenna, the first groove 5 may be an elongated groove. Optionally, as shown in fig. 5 and 6, a second accommodating cavity 6 for accommodating the main control module 2 is formed on the helmet body 1. The second accommodating cavity 6 is used for accommodating the main control module 2, so that the situation that the main control module 2 integrally protrudes out of the shell 12 can be avoided on the basis of installation of the main control module 2, and the shell 12 can play a certain protection role in the main control module 2.

In the present disclosure, the position of the second receiving chamber 6 may have various arrangements. As shown in fig. 5 and 6, in one embodiment, the second receiving cavity 6 is provided at the rear portion of the helmet body 1. When the helmet is used in practice, collision occurs, most of the situations are that the front part or the side part of the helmet body 1 collides with a foreign object, so that the probability that the main control module 2 is impacted can be reduced by arranging the second accommodating cavity 6 at the rear part of the helmet body 1, and the protection effect on the main control module 2 is improved. In addition, because helmet body 1's rear portion is thicker, not only can satisfy the setting needs that the second held chamber 6 to it does not weaken helmet body 1's protective strength yet to have set up the second and has held chamber 6.

In other embodiments of the present disclosure, the second receiving cavity 6 may also be provided at a side portion or a front portion of the helmet body 1.

As shown in fig. 6, the helmet further includes a battery module 8, and the battery module 8 may be electrically connected to the main control module 2 to supply power to the main control module 2, the capacitance detection module 7, and the detection electrode 3.
