[0016] The smart helmet for delivery personnel disclosed herein includes a helmet shell and a control module, with the control module mounted on the helmet shell. The control module includes a voice component, a communication component, and a controller. The voice component includes a microphone and a playback component, used to receive or play voice messages related to delivery orders.

[0048] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0049] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0050] See Figure 1 This illustration represents a schematic diagram of the structure of the control module 300 of the smart helmet worn by delivery personnel according to this disclosure, connected to the flexible microphone 400. In this exemplary embodiment, the smart helmet proposed in this disclosure is described as an example of a smart helmet worn by delivery personnel, such as a smart helmet worn by food delivery riders. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other application scenarios, and these changes are still within the scope of the principles of the smart helmet proposed in this disclosure.

[0051] like Figure 1 As shown, in one embodiment of this disclosure, the smart helmet worn by delivery personnel includes a helmet shell 100 and a control module 300. The control module 300 is mounted on the helmet shell 100. (See also...) Figures 2 to 6 , Figure 2 The diagram shows a representative structural schematic of the corded microphone 400 when it is detached from the control module 300; Figure 3 An exploded view of the control module 300 is shown in the figure. Figure 4 and Figure 5 The diagrams show representative structural schematics of the smart helmet from two different perspectives. Figure 6 China representatively shows Figure 5 An enlarged schematic diagram of part A in the figure. The structure, connection method, and functional relationship of the main components of the control module 300 proposed in this disclosure will be described in detail below with reference to the above figures.

[0052] like Figures 1 to 3 , Figure 7 As shown, in one embodiment of this disclosure, the control module 300 includes a voice component 302, a communication component 303, and a controller 304. The voice component 302 includes a receiver 3021 and a playback component 3022, and is used to receive or play voice messages related to delivery orders. The receiver 3021 includes a built-in microphone 30211 disposed inside the control module 300 and an external microphone 30212 connected to the outside of the control module 300. The receiver of the external microphone 30212 (e.g., the receiver 420 of the wired microphone 400 described below) extends to the wearer's facial area (e.g., forehead area, mouth and nose area). The built-in microphone 30211 and the external microphone 30212 are selectively switched under the control of the controller 304, causing one of them to operate. The communication component 303 is used for information interaction between the control module 300 and the terminal or system backend. The communication component 303 receives signals from the receiving component 3021 and sends them to the terminal or system backend, or the communication component 303 receives signals from the terminal or system backend and sends them to the playback component 3022 for playback. The controller 304 is, for example, the main control chip installed inside the control module 300. Through the above structural design, this disclosure can use the controller 304 to switch between the built-in microphone 30211 and the external microphone 30212, avoiding the problems of limited wind noise suppression, unstable sound reception, and easy damage or loss that exist when using a single silicon microphone solution or a single telescopic microphone solution. In particular, through the redundant design of the built-in microphone 30211 and the external microphone 30212, this disclosure can improve the fault tolerance of the device. In addition, through the layout of the external microphone 30212 extending to the delivery personnel's face area, this disclosure can reduce wind noise interference when switching the external microphone 30212 for sound reception.

[0053] In one embodiment of this disclosure, the controller 304 may switch to using the external microphone 30212 for sound pickup when the delivery vehicle is moving at high speed, such as above 30 km / h. At this speed, wind noise significantly interferes with the built-in microphone 30211, resulting in poor sound clarity. Switching to the external microphone 30212 reduces wind noise interference during high-speed movement and improves the sound clarity of the control module 300. Furthermore, the controller 304 may switch to using the built-in microphone 30211 when the delivery vehicle is moving at low speed, such as below 30 km / h. At this speed, wind noise interferes less with the built-in microphone 30211, and the built-in microphone 30211 is sufficient for sound clarity. Switching to the built-in microphone 30211 avoids the impact on sound pickup functionality caused by the external microphone 30212 being ineffectively connected or damaged. Furthermore, the aforementioned switching of the recording mode can be directly executed by the controller 304 or switched by the rider operating the relevant buttons. Through this structural design, this disclosure can switch between the operation of the built-in microphone 30211 and the external microphone 30212, avoiding problems such as limited wind noise suppression, unstable sound pickup, and susceptibility to damage or loss that exist when using a single silicon microphone solution or a single telescopic microphone solution. The redundant design of the built-in microphone 30211 and the external microphone 30212 improves the fault tolerance of the device. Additionally, the layout of the external microphone 30212 extending to the delivery rider's face area reduces wind noise interference when switching to the external microphone 30212.

[0054] It should be noted that this embodiment uses the example of controller 304 switching the radio mode according to the moving speed of the delivery vehicle. It should be understood that in other embodiments of this disclosure, controller 304 may also switch between the built-in microphone 30211 and the external microphone 30212 according to other conditions, such as strong wind and light wind (which can be achieved using an anemometer), high temperature and low temperature (which can be achieved using a temperature sensor), etc., and is not limited to this embodiment.

[0055] In one embodiment of this disclosure, the boundary between high-speed and low-speed movement can be, for example, 20 km / h to 40 km / h, such as 20 km / h, 25 km / h, 30 km / h, 40 km / h, etc. Furthermore, regardless of the delivery vehicle's speed, the external microphone 30212 can be used at various speeds. For example, taking an electric vehicle with a maximum speed of 60 km / h as an example, the external microphone 30212 can pick up sound at any speed from 0 to 60 km / h.

[0056] In one embodiment of this disclosure, the control module 300 may contain a speed sensor that measures the current moving speed of the delivery vehicle. Based on the speed sensor's measurement, the controller 304 switches between the built-in microphone 30211 and the external microphone 30212. For example, if the moving speed measured by the speed sensor is greater than a speed threshold, the controller 304 switches to the external microphone 30212; if the moving speed measured by the speed sensor is less than or equal to a speed threshold, the controller 304 switches to the built-in microphone 30211. Furthermore, the controller 304 can be a main control chip or a circuit; that is, the switching of the radio mode using the controller 304 in this disclosure does not rely on computer programming.

[0057] In one embodiment of this disclosure, the controller 304 can switch the built-in microphone 30211 to work when the external microphone 30212 connection fails. "Connection failure" can be understood as the controller 304 not receiving voice signals from the external microphone 30212. Specifically, this could be the state where the external microphone 30212 is removed from the control module 300 (e.g., the connector 410 of the corded microphone 400 is pulled out), or a state where the signal is interrupted due to a malfunction in either the external microphone 30212 or the connection component used by the control module 300 to connect to the external microphone 30212. For example, if the external microphone 30212 connector is not inserted into the microphone connector of the control module 300 (i.e., the external microphone 30212 is not installed), the control module 300 defaults to using the built-in microphone 30211 for recording. When the microphone connector is inserted into the external microphone 30212 connector, the controller 304 receives the corresponding signal and switches to using the external microphone 30212 for recording. Specifically, taking the design of the controller 304 switching the sound reception mode based on the measurement results of the humidity sensor as an example, when the moving speed measured by the speed sensor is greater than the speed threshold and the control module 300 is effectively connected to the external microphone 30212, the controller 304 switches the external microphone 30212 to work. When the moving speed is greater than the speed threshold and the connection between the control module 300 and the external microphone 30212 fails, the controller 304 switches the built-in microphone 30211 to work. For example, at this time, the controller 304 will automatically lock the built-in microphone 30211 as the only sound input source.

[0058] In one embodiment of this disclosure, the controller 304 may integrate radio mode switching logic, that is, the control module 300 can determine which microphone, the built-in microphone 30211 or the external microphone 30212, should be switched to work at the current time, and accordingly switch between the built-in microphone 30211 and the external microphone 30212 to detect and control the microphone status in real time. Furthermore, the controller 304 may also integrate a speed sensor to detect movement speed in real time. In addition to the above-mentioned radio mode switching function, the controller 304 may also implement other functions of the control module 300, such as voice interaction control, button operation control, etc.

[0059] See also Figure 6 , Figure 6 The diagram shows a partially enlarged view of the control module 300 installed in a smart helmet. In one embodiment of this disclosure, a sound outlet 140 is provided on the helmet shell 100 at a position corresponding to the built-in microphone 30211, and a windproof foam 141 can be disposed inside the sound outlet 140. Through the above structural design, this disclosure can utilize the windproof foam 141 to reduce noise interference when the built-in microphone 30211 is picking up sound (e.g., wind noise during high-speed cycling).

[0060] like Figure 3 As shown, in one embodiment of this disclosure, the built-in microphone 30211 can be a silicon microphone 3302, which can be disposed inside the control module 300. For example, the silicon microphone 3302 can be integrated on a circuit board (e.g., a PCB board) inside the control module 300, and the silicon microphone 3302 is located in the area of ​​the control module 300 corresponding to the wearer's ear. Based on this, the control module 300 can be provided with a sound outlet, for example, the sound outlet can be disposed on the part of the control module 300 closer to the wearer (back cover 322), and the sound outlet is arranged corresponding to the position of the silicon microphone 3302. When the control module 300 switches to the silicon microphone 3302 for sound pickup, ambient noise can be filtered using, for example, an AI noise reduction algorithm integrated into the controller 304. Accordingly, by integrating the silicon microphone 3302 onto the circuit board, a modular design of the control module 300 can be achieved, facilitating maintenance and extending the device's lifespan.

[0061] like Figure 3 As shown, in one embodiment of this disclosure, the control module 300 may include a front housing 321 and a rear housing 322, which are assembled together. (See attached reference.) Figure 4When the control module 300 is installed in a smart helmet, the front shell 321 is the shell on the side of the helmet shell 100 away from the smart helmet, and the rear shell 322 is the shell on the side of the control module 300 closer to the helmet shell 100. The front shell 321 and the rear shell 322 fit together to form a cavity for accommodating various components, such as the controller 304, silicon microphone 3302, and circuit board mentioned in this specification. Taking the structure shown in the attached drawings as an example, the circuit board can be located in the rear shell 322.

[0062] like Figure 1 and Figure 2 As shown, and in conjunction with other references Figure 6 In one embodiment of this disclosure, the external microphone 30212 can be a wired microphone 400, which is arranged in a concealed manner within the inner cavity of the helmet shell 100. For example, the wired microphone 400 includes a microphone 420 and a connecting cable 430. The microphone 420 is concealed within the inner cavity of the helmet shell 100, and is at least partially accommodated in a receiving groove provided on the inner side of the helmet shell. The microphone 420 is located in the area of ​​the helmet shell 100 corresponding to the wearer's forehead, and is used for sound pickup. The connecting cable 430 is concealed within the inner cavity of the helmet shell 100, and is at least partially accommodated in a wire groove 130 provided on the inner side of the helmet shell. One end of the connecting cable 430 is connected to the microphone 420, and the other end is connected to the control module 300. When the delivery personnel wear a smart helmet, the microphone 420 of the flexible microphone 400 can be positioned in the area of ​​the delivery personnel's forehead, and the connecting cable 430 can be positioned in the area of ​​one side of the head. Through the above structural design, this disclosure utilizes the cable groove 130 and the receiving groove of the helmet shell 100 to respectively accommodate the connecting cable 430 and the microphone 420, thereby achieving a concealed installation of the flexible microphone 400 within the inner cavity of the helmet shell 100, while also taking into account wind noise reduction and the integrity of the helmet's appearance.

[0063] Based on the structural design of the wired microphone 400, which includes a microphone 420, in one embodiment of this disclosure, the microphone 420 may be covered with a wind-repellent mesh cover. Through this structural design, this disclosure utilizes the wind-repellent mesh cover to guide airflow around the pickup hole of the microphone 420, further suppressing wind noise.

[0064] like Figure 1 and Figure 2As shown, in one embodiment of this disclosure, a microphone connector (e.g., a 3.5mm audio female connector 3320) may be provided externally to the control module 300, thereby allowing an external microphone 30212 to be detachably connected to the control module 300. The external microphone 30212 is provided with a connector (e.g., the connector 410 of a wired microphone 400), through which the external microphone 30212 is detachably connected to the microphone connector. Through this structural design, this disclosure enables the detachment of the external microphone 30212 from the control module 300, facilitating the individual replacement of either the external microphone 30212 or the control module 300, thus reducing maintenance costs.

[0065] Based on the structural design of the external microphone 30212 being detachably connected to the control module 300, in one embodiment of this disclosure, the control module 300 can selectively connect multiple different types of external microphones 30212, and these external microphones 30212 include at least a wired microphone 400 and a telescopic microphone. The receiver 420 of the wired microphone is located on the helmet shell 100 corresponding to the wearer's forehead, while the telescopic microphone extends to the wearer's mouth and nose area. Through this design, this disclosure utilizes the detachable connection between the external microphone 30212 and the control module 300, enabling delivery capacity to flexibly select different types of external microphones 30212 according to different needs such as usage habits, performance characteristics, and price differences, thereby increasing product freedom and flexibility.

[0066] like Figure 3 As shown, in one embodiment of this disclosure, a circuit board (which can serve as the control board of the control module 300) may be disposed inside the cavity of the control module 300. The circuit board may be provided with electronic components such as chips, antennas, a Type-C female connector 3318, and a battery connector. The battery connector is used to connect to the battery 3322. Furthermore, the control module 300 may be provided with a charging interface (e.g., a Type-C female connector 3318), which is connected to the battery 3322 via the battery connector. The Type-C female connector 3318 serves as a charging interface for connecting an external power source to the control module 300, and the charging interface is exposed on the surface of the control module 300 for connecting a cable 500 to achieve charging or data interaction functions. Unlike helmets used in other scenarios, the helmets worn by delivery personnel require special attention due to their role in order processing. Furthermore, the control module 300 is designed for work scenario detection and radio mode switching, necessitating charging. The Type-C female connector 3318 can meet the charging needs of the control module 300. Additionally, a charging plug can be provided at the charging port to provide dust and water protection when the cable 500 is not plugged in.

[0067] In one embodiment of this disclosure, the control module 300 is detachably connected to the helmet shell 100. Through this structural design, the present disclosure enables the detachable installation of the control module 300 on the smart helmet. Accordingly, the present disclosure allows for direct removal of the control module 300 during seasonal changes, for example, from a summer helmet to a winter helmet, thereby significantly saving costs and avoiding idle waste. Furthermore, the present disclosure facilitates the separate repair or replacement of either the helmet shell 100 or the control module 300, reducing maintenance costs. Additionally, for new riders, the present disclosure allows for separate operation of the helmet and control module 300; new riders only need to pay for the helmet and install the control module 300 to wear the new smart helmet, reducing the rider's burden.

[0068] It should be noted that the smart helmets worn by delivery personnel shown in the accompanying drawings and described in this specification are merely a few examples among many smart helmets capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the smart helmets shown in the accompanying drawings or described in this specification.

[0069] In summary, the smart helmet for delivery personnel disclosed herein includes a helmet shell 100 and a control module 300, wherein the control module 300 is mounted on the helmet shell 100; the control module 300 is provided with a voice component 302, a communication component 303, and a controller 304; the voice component 302 includes a microphone 3021 and a speaker 3022, and is used to receive or play voice related to delivery orders; the microphone 3021 includes a built-in microphone 30211 disposed inside the control module 300 and a microphone connected to the outside of the control module. An external microphone 30212 is provided, with its microphone extending to the wearer's face. The built-in microphone 30211 and the external microphone 30212 are selectively switched under the control of the controller 304, allowing one to operate. A communication component 303 is used to control the information interaction between the control module 300 and the terminal or system backend. The communication component 303 receives signals from the microphone 3021 and sends them to the terminal or system backend, or receives signals from the terminal or system backend and sends them to the playback component 3022 for playback. Through this structural design, the present invention can use the controller 304 to switch between the built-in microphone 30211 and the external microphone 30212, avoiding problems such as limited wind noise suppression, unstable sound reception, and susceptibility to damage or loss that exist when using a single silicon microphone solution or a single telescopic microphone solution. Furthermore, the redundant design of the built-in microphone 30211 and the external microphone 30212 improves the fault tolerance of the device. In addition, by extending the external microphone 30212 to the face area of ​​the delivery personnel, this disclosure can reduce wind noise interference when switching the external microphone 30212 for sound recording.
