[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be fully described below in combination with the drawings in the embodiments of the present invention through specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work fall within the protection scope of the present invention.

[0038] Figure 1 is a structural schematic diagram of a helmet provided by an embodiment of the present invention, Figure 2 is a schematic diagram of a helmet provided by an embodiment of the present invention, with reference to Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a helmet 10, which includes a shell 100 and a direction acquisition unit 210, a light emitting unit 220, a light position adjustment unit 230 and a processor 240 arranged on the shell 100; the direction acquisition unit 210 is connected to the processor 240, and the direction acquisition unit 240 is used to obtain motion information of the shell 100 and transmit the motion information to the processor 240; the processor 240 determines the motion trajectory of the shell 100 according to the motion information; the light emitting unit 220 is connected to the processor 240, and the processor 240 adjusts the illumination brightness value of the light emitting unit 220 according to the motion trajectory; the light position adjustment unit 230 is connected to the processor 240, and the light position adjustment unit 230 is mechanically connected to the light emitting unit 220, and the processor 240 adjusts the position of the light position adjustment unit 230 according to the motion trajectory, and the light position adjustment unit 230 drives the light emitting unit 220 to adjust the position.

[0039] The embodiment of the present invention provides a helmet 10, which is worn on the head to protect the operator's head. Figure 1 and Figure 2 As shown, the helmet 10 provided in the embodiment of the present invention includes a shell 100, wherein the shell 100 can be understood as the main structure of the helmet 10, and the operator wears the helmet 10 through the shell 100. The helmet 10 also includes a direction acquisition unit 210, a light emitting unit 220, a light position adjustment unit 230, and a processor 240, etc. The direction acquisition unit 210, the light emitting unit 220, the light position adjustment unit 230, and the processor 240 are arranged on the shell 100 to enrich the functions of the helmet 10.

[0040] Among them, the direction acquisition unit 210 is used to obtain the motion information of the shell 100, and the motion information is the deflection of the shell 100 in multiple directions and different deflection speeds, etc. In other words, the motion information can be understood as the relevant parameters of the shell 100 to change the motion state adjustment. The shell 100 has motion information captured by the direction acquisition unit 210 because the operator wears the helmet 10 and adjusts the head state, thereby driving the shell 100 to have relevant motion state adjustments, and then the direction acquisition unit 210 can obtain the motion information of the shell 100. Further, the direction acquisition unit 210 is connected to the processor 240. Exemplarily, the direction acquisition unit 210 and the processor 240 can be a communication connection or an electrical connection. The embodiment of the present invention does not specifically limit the connection method between the direction acquisition unit 210 and the processor 240. The processor 240 can determine the motion trajectory of the shell 100 based on the motion information.

[0041] Optionally, the processor 240 can use a Kalman filter data fusion algorithm to comprehensively process the data obtained by the direction acquisition unit 210 to obtain stable and accurate posture information of the head of the operator wearing the helmet 10. Further, the processor 240 calculates the pitch angle (Pitch), roll angle (Roll) and yaw angle (Yaw) of the head based on the fused data (i.e., posture information), thereby obtaining the motion trajectory and angle change information of the head of the operator wearing the helmet 10.

[0042] Furthermore, the direction acquisition unit 210 can acquire the motion information of the housing 100 in real time, and transmit the motion information in real time to the processor 240. The processor 240 determines the motion track of the housing 100 by analyzing the motion information, and further determines the current sight direction.

[0043] Furthermore, the light emitting unit 220 on the helmet 10 can emit light (refer to Figure 2The middle light a) is used to illuminate the front sight and provide light for the operator wearing the helmet 10. The operator wearing the helmet 10 can perform related work in low light or complex environment, which reflects the universality of the helmet 10. Among them, the light-emitting unit 220 is connected to the processor 240, and the processor 240 adjusts the illumination brightness value of the light-emitting unit 220 according to the motion trajectory. Exemplarily, the light-emitting unit 220 and the processor 240 can be a communication connection or an electrical connection. The embodiment of the present invention does not specifically limit the connection mode between the light-emitting unit 220 and the processor 240. Specifically, the processor 240 first determines the motion information of the shell 100 through the direction acquisition unit 210 to form a motion trajectory, and can determine the brightness demand according to the motion trajectory. If the ambient brightness on the motion trajectory is low, the light-emitting unit 220 can be controlled to adjust the brightness, that is, to increase the illumination brightness value of the light-emitting unit 220, thereby ensuring that the operator wearing the helmet 10 works more conveniently and safely, and improving the reliability and functionality of the helmet 10.

[0044] Furthermore, the housing 100 further includes a light position adjustment unit 230, which is mechanically connected to the light emitting unit 220, and it can also be understood that the light position adjustment unit 230 can drive the light emitting unit 220 to adjust its position. The light position adjustment unit 230 is connected to the processor 240, and illustratively, the light position adjustment unit 230 and the processor 240 can be connected by communication or by electrical connection. The embodiment of the present invention does not specifically limit the connection method between the light position adjustment unit 230 and the processor 240. Among them, the processor 240 adjusts the brightness on the motion trajectory of the shell 100 according to the acquisition of the motion trajectory of the shell 100, that is, increases the illumination brightness value of the light-emitting unit 220. At the same time, it is also necessary to ensure that the light emitted by the light-emitting unit 220 is irradiated on the motion trajectory, so the light position adjustment unit 230 is controlled to drive the light-emitting unit 220 to adjust its position to ensure sufficient light, that is, to ensure that when the operator wears the helmet 10, if the operator's head moves, the helmet 10 can adjust the brightness of its line of sight according to the direction and angle of its movement, to ensure that the operator wearing the helmet 10 can work normally in poor ambient light or complex lighting conditions.

[0045] Optionally, if the motion information acquired by the processor 240 does not change within a period of time, for example, within 1 to 30 seconds (the specific time value can be adaptively adjusted according to different situations, and the embodiment of the present invention does not specifically limit this), when the motion information acquired by the processor 240 is in a static state, the processor 240 can determine that the current shell 100 is in a static state, so that the head of the operator wearing the helmet 10 does not move, and the processor 240 can control the light emitting unit 220 and the light position adjustment unit 230 not to make additional adjustments, that is, to avoid unnecessary adjustment processes. Optionally, the processor 240 can continuously optimize the judgment of the motion trajectory and the control of the light emitting unit 220 and the light position adjustment unit 230 (for example, shortening the adjustment time of the light emitting unit 220 and the light position adjustment unit 230 according to the motion trajectory) based on the acquired motion information, etc., to ensure that the adjustment of the light emitting unit 220 and the light position adjustment unit 230 can be performed as synchronously as possible with the motion change of the shell 100, thereby reducing the lag of the light and bringing a better experience to the operator.

[0046] In summary, an embodiment of the present invention provides a helmet, which includes a shell and a direction acquisition unit, a light emitting unit, a light position adjustment unit and a processor arranged on the shell. The shell is used to carry other devices on the one hand, and provide a wearing space for the operator on the other hand, thereby realizing the wearability of the helmet; further, the direction acquisition unit is used to obtain motion information of the shell and transmit the motion information to the processor; the processor determines the motion trajectory of the shell according to the motion information; the processor can further adjust the illumination brightness value of the light emitting unit according to the motion trajectory, and the processor can also adjust the position of the light position adjustment unit according to the motion trajectory, and the light position adjustment unit drives the light emitting unit to adjust the position. By using the helmet provided by the embodiment, the motion trajectory of the shell can be determined according to the wearer's movement, and the brightness and position of the light can be adjusted according to the motion trajectory, thereby improving the practicality and safety of the helmet.

[0047] Figure 3 is a schematic diagram of the structure of another helmet provided by an embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the direction acquisition unit 210 includes a gyroscope 211 and an accelerometer 212 ; the gyroscope 211 is used to acquire the angular velocity change value of the housing 100 ; and the accelerometer 212 is used to acquire the linear acceleration of the housing 100 .

[0048] For further reference, Figure 3As shown, the direction acquisition unit 210 includes a gyroscope 211 and an accelerometer 212, wherein the rigid body that the gyroscope 211 rotates at high speed around a fulcrum is called a gyroscope. The gyroscope generally refers to a symmetrical gyroscope, which is a rigid body with uniform mass distribution and axially symmetrical shape, and its geometric symmetry axis is its rotation axis. The gyroscope 211 can be used to obtain the angular velocity change value of the shell 100. Specifically, the gyroscope 211 is used to measure the angular velocity of the head of the operator wearing the helmet 10, and can sense the rotational movement of the head on three axes (lateral, longitudinal and vertical directions). The accelerometer 212 is an instrument for measuring the linear acceleration of the carrier, which is composed of a detection mass (also called a sensitive mass), a support, a potentiometer, a spring, a damper and a shell. The specific structure of the accelerometer 212 is not described in detail in the embodiment of the present invention, and the accelerometer 212 is used to obtain the linear acceleration of the shell 100. Specifically, the accelerometer 212 can sense the displacement and tilt angle of the head of the operator wearing the helmet 10 in space. The processor 240 obtains the motion trajectory of the shell 100 more accurately according to the angular velocity change value of the shell 100 and the linear acceleration of the shell 100 .

[0049] Optionally, the direction acquisition unit further includes a magnetometer; the magnetometer is used to correct the angular velocity change value.

[0050] Furthermore, the direction acquisition unit also includes a magnetometer. The magnetometer is used to compensate for the drift problem of the gyroscope, which can be understood as compensating for the angular velocity change value obtained by the gyroscope to ensure the accuracy of the angular velocity change value. Specifically, the magnetometer performs attitude calibration based on the direction data of the head of the operator wearing the helmet provided by the processor and combined with the geomagnetic field information, thereby ensuring that the information obtained by the processor is more accurate, thereby ensuring that the function of the helmet is more reliable.

[0051] Continue to refer Figure 2 and Figure 3 As shown, the helmet 10 further includes a light brightness acquisition unit 250 located on the shell 100 ; the light brightness acquisition unit 250 is connected to the processor 240 , and the light brightness acquisition unit 250 is used to detect the ambient brightness value of the shell 100 on the motion trajectory.

[0052] For further reference, Figure 3 As shown, the helmet 10 further includes a light brightness acquisition unit 250 located on the housing 100. The light brightness acquisition unit 250 may be a light sensor for acquiring the brightness of the environment. The light brightness acquisition unit 250 is connected to the processor 240. Exemplarily, the light brightness acquisition unit 250 and the processor 240 may be connected by communication or by electrical connection. The embodiment of the present invention does not specifically limit the connection mode between the light brightness acquisition unit 250 and the processor 240.

[0053] By adding a light brightness acquisition unit 250 to the helmet 10, the processor 240 can adaptively adjust the brightness of the light-emitting unit 220 according to the detected ambient brightness. On the one hand, it can provide the operator wearing the helmet 10 with the closest lighting effect, and on the other hand, it can also save electricity and avoid unnecessary waste of electricity. It can be understood that the intelligent light adjustment of the helmet 10 is realized in combination with the light brightness acquisition unit 250.

[0054] Optionally, the light position adjustment unit includes an electrode and a universal joint; the light emitting unit is connected to the electrode via the universal joint.

[0055] Specifically, the light position adjustment unit includes an electrode and a universal joint, wherein the electrode can be a stepping motor or a servo electrode. When the light position adjustment unit receives an adjustment instruction from a processor, the electrode provides power to drive the light-emitting unit to adjust its position. The universal joint is a universal joint, which is a component for achieving variable angle power transmission. The light-emitting unit is connected to the electrode through the universal joint, which can achieve multi-angle adjustment of the light-emitting unit and ensure the flexibility of position adjustment of the light-emitting unit.

[0056] Furthermore, the processor pre-stores a motion mapping algorithm, and can interpret the acquired motion information into corresponding electrode rotation instructions according to the motion mapping algorithm, thereby adjusting the position of the electrode according to the motion trajectory. Since the light-emitting unit is mounted on a universal joint controlled by a stepper motor or a servo motor, the precise control of the motor enables the light direction to quickly rotate with the head of the operator wearing the helmet.

[0057] For example, when the operator wearing the helmet turns his head to the left, the motor will adaptively rotate to the left by a corresponding angle to align the light with the sight. When the operator wearing the helmet tilts his head up or down, the motor will adjust the vertical angle of the light unit to ensure that the light covers the sight range.

[0058] Optionally, the light emitting unit includes a light emitting diode.

[0059] Specifically, the light-emitting unit may be a light-emitting diode, which is a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes and is widely used in the field of lighting.

[0060] Continue to refer Figure 2 and Figure 3 As shown, the helmet 10 also includes a voice acquisition unit 260; the voice acquisition unit 260 is connected to the processor 240, and the voice acquisition unit 260 is used to acquire voice instructions and transmit the voice instructions to the processor 240, and the processor 240 adjusts the light position adjustment unit 230 and / or the light emitting unit 220 according to the voice instructions.

[0061] For further reference, Figure 3 As shown, the helmet 10 further includes a voice acquisition unit 260, which may be a microphone or the like, and may acquire the voice of the operator wearing the helmet 10. The voice acquisition unit 260 is connected to the processor 240. Exemplarily, the voice acquisition unit 260 and the processor 240 may be connected by communication or by electrical connection. The embodiment of the present invention does not specifically limit the connection mode between the voice acquisition unit 260 and the processor 240.

[0062] By adding a voice acquisition unit 260 to the helmet 10, the processor 240 may include a voice recognition module, which can perform data processing based on the detected voice information and generate corresponding voice instructions. The processor 240 then controls the light position adjustment unit 230 and / or the light emitting unit 220 according to the corresponding voice instructions.

[0063] Exemplarily, an operator wearing the helmet 10 outputs voice information such as "move left", "turn on the light", "brighten" and "focus", and the voice acquisition unit 260 transmits the voice information to the processor 240. The processor 240 performs corresponding data processing to generate corresponding control instructions, and controls the light position adjustment unit 230 to adjust the position of the light-emitting unit 220 or adjust the light-emitting unit 220 according to the control instructions. The embodiment of the present invention does not provide a specific description of this. In combination with the voice acquisition unit 260, the helmet 10 has a voice control function. The operator interacts with the helmet 10 through voice commands. The voice acquisition unit 260 receives the voice signal and transmits it to the voice recognition module of the processor 240. The recognition result is parsed by the processor and the corresponding operation is performed, such as turning on or off the headlights, adjusting the brightness, and switching the lighting mode.

[0065] Specifically, refer to Figure 3 and Figure 4 As shown, the helmet 10 includes a battery 310, which is electrically connected to the light-emitting unit 220 to provide electrical energy for the light-emitting unit 310 to perform a light-emitting display. The battery 310 can ensure that the helmet 10 works for a long time. Furthermore, the battery 310 can also be electrically connected to other structures in the helmet 10 that require electrical energy.

[0066] refer to Figure 4As shown, the helmet 10 includes a charging port 320, which is electrically connected to the light-emitting unit 220. The charging port 320 can be electrically connected to a charger (not specifically shown in the figure), and the charger provides power to the light-emitting unit 310 through the charging port 320. Further, the charging port 320 can also be electrically connected to other structures that require electricity.

[0068] Based on the same inventive concept, an embodiment of the present invention further provides a method for adjusting a helmet.

[0069] S110 , controlling the direction acquisition unit to acquire the motion information of the shell.

[0070] S120 , driving the motion trajectory of the shell according to the motion information.

[0071] The helmet is worn on the head to protect the operator's head. The shell can be understood as the main structure of the helmet, and the operator wears the helmet through the shell. The helmet also includes a direction acquisition unit, a light emitting unit, a light position adjustment unit, and a processor, etc. The direction acquisition unit, the light emitting unit, the light position adjustment unit, and the processor are arranged on the shell to enrich the functions of the helmet.

Further, the processor calculates the pitch angle (Pitch), roll angle (Roll) and yaw angle (Yaw) of the head based on the fused data (i.e., posture information), thereby obtaining the movement trajectory and angle change information of the head of the operator wearing the helmet.

[0074] Furthermore, the direction acquisition unit can acquire the motion information of the shell in real time, and transmit the motion information to the processor in real time. The processor determines the motion track of the shell by analyzing the motion information, and further determines the current sight direction.

[0075] S130, adjusting the position of the light position adjustment unit according to the motion trajectory.

[0076] S140, adjusting the illumination brightness value of the light-emitting unit according to the motion trajectory.

[0077] Furthermore, the light-emitting unit on the helmet can emit light to illuminate the front line of sight and provide light for the operator wearing the helmet. The operator wearing the helmet can perform related work in low-light or complex environments, which reflects the universality of the helmet. Among them, the light-emitting unit is connected to the processor, and the processor adjusts the illumination brightness value of the light-emitting unit according to the motion trajectory. Exemplarily, the light-emitting unit and the processor can be connected by communication or by electricity. The embodiment of the present invention does not specifically limit the connection method between the light-emitting unit and the processor.

[0078] Furthermore, the shell also includes a light position adjustment unit, which is mechanically connected to the light emitting unit, and can also be understood as the light position adjustment unit can drive the light emitting unit to adjust its position. Wherein, the light position adjustment unit is connected to the processor. Exemplarily, the light position adjustment unit and the processor can be connected by communication or by electricity.

Wherein, the processor adjusts the brightness on the motion trajectory of the shell according to the acquisition of the motion trajectory of the shell, that is, increases the illumination brightness value of the light emitting unit, and also needs to ensure that the light emitted by the light emitting unit is irradiated on the motion trajectory, so the light position adjustment unit is controlled to drive the light emitting unit to adjust its position to ensure sufficient light, that is, when the operator wears a helmet, if the operator's head moves, the helmet can adjust the brightness of its line of sight according to the direction and angle of its movement, to ensure that the operator wearing the helmet can work normally in the case of poor ambient light or complex light conditions.

[0079] Optionally, if the motion information acquired by the processor does not change within a period of time, for example, within 1 to 30 seconds (the specific time value can be adaptively adjusted according to different situations, and the embodiment of the present invention does not specifically limit this), when the motion information acquired by the processor is in a static state, the processor can determine that the current shell is in a static state, so that the head of the operator wearing the helmet does not move, and the processor can control the light-emitting unit and the light position adjustment unit not to make additional adjustments, that is, to avoid unnecessary adjustment processes. Optionally, the processor can continuously optimize the judgment of the motion trajectory and the control of the light-emitting unit and the light position adjustment unit based on the acquired motion information, etc. (for example, shortening the adjustment time of the light-emitting unit and the light position adjustment unit according to the motion trajectory), to ensure that the adjustment of the light-emitting unit and the light position adjustment unit can be performed as synchronously as possible with the movement changes of the shell, thereby reducing the lag of the light and bringing a better experience to the operator.

[0080] In summary, in the helmet adjustment method provided by the embodiment of the present invention, the direction acquisition unit is used to obtain the motion information of the shell and transmit the motion information to the processor; the processor determines the motion trajectory of the shell according to the motion information; the processor can further adjust the illumination brightness value of the light-emitting unit according to the motion trajectory, and the processor can also adjust the position of the light position adjustment unit according to the motion trajectory. The light position adjustment unit drives the light-emitting unit to adjust the position. By using the helmet provided by the embodiment, the motion trajectory of the shell can be determined according to the wearer's movement, and the brightness and position of the light can be adjusted according to the motion trajectory, thereby improving the practicality and safety of the helmet.

[0081] Figure 7FIG. 1 is a schematic diagram of another helmet adjustment method provided by an embodiment of the present invention, referring to FIG. Figure 7 As shown, the adjustment method also includes:

[0082] S210 , controlling the direction acquisition unit to acquire movement information of the shell.

[0083] S220 , driving the motion trajectory of the shell according to the motion information.

[0084] S230, adjusting the position of the light position adjustment unit according to the motion trajectory.

[0085] S240, controlling the light brightness acquisition unit to detect the ambient brightness value of the shell on the motion trajectory.

[0086] S250, obtaining the ambient brightness value and determining whether the ambient brightness value is less than the preset brightness value. If so, executing S270; if not, executing S260;

[0087] S260, controlling the light-emitting unit to maintain the illumination brightness value.

[0088] S270, controlling the light-emitting unit to adjust the illumination brightness value to the adjusted brightness value.

[0089] Specifically, the helmet also includes a light brightness acquisition unit located on the shell, and the light brightness acquisition unit can be a light sensor for acquiring the brightness of the environment. The light brightness acquisition unit is connected to the processor. Exemplarily, the light brightness acquisition unit and the processor can be communicatively connected or electrically connected. The embodiment of the present invention does not specifically limit the connection method between the light brightness acquisition unit and the processor. By adding a light brightness acquisition unit to the helmet, the processor can adaptively adjust the brightness of the light-emitting unit according to the detected ambient brightness. On the one hand, it can provide the operator wearing the helmet with the closest lighting effect, and on the other hand, it can also save electricity and avoid unnecessary waste of electricity. It can be understood as combining the light brightness acquisition unit to realize intelligent light adjustment of the helmet.

[0090] Specifically, the processor obtains the ambient brightness value through the light brightness acquisition unit and judges the ambient brightness value. When the ambient brightness value is less than the preset brightness value, it proves that the ambient brightness of the current helmet is low. In order to ensure the working environment of the operator wearing the helmet, it is necessary to control the light-emitting unit to increase the brightness value of its illumination, that is, to increase the original illumination brightness value of the light-emitting unit, and adjust the brightness value by the increased value; if the ambient brightness value is not less than the preset brightness value, it proves that the ambient brightness value of the current helmet is high, which can ensure the normal operation of the operator wearing the helmet. Among them, the preset brightness value can be understood as the brightness value that meets the working vision requirements when the current helmet is working, which can be further adjusted according to the differences in the practical scenarios of the helmet, and the embodiment of the present invention does not specifically limit this.
