[0036] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0037] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0038] For electric or motorized riding tools, for safety reasons, relevant regulations have been issued to require riders to wear helmets when riding electric or motorized riding tools. For shared electric motorcycles, in order to comply with the requirements of relevant regulations, the rider must wear a helmet before starting the motorcycle, thereby improving the safety of the rider when riding.

[0039] Existing helmet wearing detection usually uses detection components arranged on the buckle assembly for detection. The buckle assembly buckles after the helmet is in place to prevent the helmet from falling off the user's head. However, since the detection components are currently provided in the buckle assembly, the size of the buckle assembly is large. The buckle assembly reduces the wearing comfort of the entire helmet, especially when worn for a long time, it will cause pressure and discomfort in the lower jaw. In addition, the current buckle connection method also has the problem of false triggering, which may cause the user to be triggered when not wearing it, thus affecting the user's riding safety.

[0040] The embodiments of the present disclosure provide a snap-fit ​​assembly and a helmet using the snap-fit ​​assembly to solve or at least partially solve the above-mentioned problems or other potential problems existing in the above-mentioned traditional solutions. The snap-fit ​​assembly according to the embodiments of the present disclosure can be applied to any appropriate occasions where two separate components (such as the two ends of a lanyard) need to be snapped together and snap-fit ​​detection needs to be provided, such as helmets for electric vehicles, buckles for work badges or badge lanyards, etc. The embodiments of the present disclosure mainly describe the concept of the present disclosure by taking the snap-fit ​​assembly applied to a helmet for an electric vehicle as an example. It should be understood that the application of the snap-fit ​​assembly to other components or scenarios is similar and will not be described separately below.

[0041] Embodiments according to the present disclosure will be described below with reference to the accompanying drawings. Figure 1 A three-dimensional view showing a snap-fit ​​assembly according to an embodiment of the present disclosure that has not yet been snapped together is shown; Figure 2 shows a perspective view of the snap-fit ​​components snapped together, Figure 3 An exploded view showing a snap-fit ​​assembly according to some other embodiments of the present disclosure; and Figure 4 FIG. 2 shows a side cross-sectional view of a snap-fit ​​assembly according to some other embodiments of the present disclosure. Figures 1 to 4 As shown, in general, the snap-fit ​​assembly according to the embodiment of the present disclosure includes a female plug component 101, a male plug component 102 and a detection component 103. The female plug component 101 has an insertion hole and a first matching structure 1011 formed inside the insertion hole.

[0042] The male plug component 102 is formed by two shells that are snapped together, that is, a first shell 1021 and a second shell 1022, so as to maximize the use of space, make the snap-fit ​​assembly more compact and thus have a smaller volume. The male plug component 102 also includes an external insertion portion 1023 and a second mating structure 1024 formed on the external insertion portion 1023. In some embodiments, as Figures 1 to 4As shown, the external insert portion 1023 may be formed on the first housing 1021. In some alternative embodiments, the external insert portion 1023 may also be formed or defined by the first housing 1021 and the second housing 1022, which will be further described below.

[0043] The first housing 1021 and the second housing 1022 are buckled together to define an internal accommodation space. The internal accommodation space is used to accommodate the detection component 103. As the external insertion portion 1023 of the male plug component 102 is inserted into the insertion hole of the female plug component 101, the second matching structure 1024 can be combined with the first matching structure 1011 in the insertion hole to complete the buckling of the buckling assembly. Figure 1 , Figure 2 and Figure 4 shown.

[0044] In some embodiments, the first matching structure 1011 and the second matching structure 1024 may adopt a sawtooth structure, such as Figure 1 and Figure 4 As shown. For example, the first matching structure 1011 and the second matching structure 1024 can both include multiple levels of saw teeth. Each level of saw teeth can be asymmetric saw teeth, that is, when placed horizontally, one side of each saw tooth has a larger angle relative to the horizontal plane, and the other side has a smaller angle, so that during the insertion process, the side surfaces with smaller angles can contact each other, making it easier for the external insertion part 1023 to be inserted into the insertion hole. At the same time, after being inserted into place, the side surfaces with larger angles abut against each other, thereby completing the fastening of the fastening assembly.

[0045] The use of multi-stage saw teeth can also facilitate the adjustment of the tightness of the fastening assembly. For example, if the fastening assembly needs to be fastened more tightly, the saw teeth on the inner side of the multi-stage saw teeth can be meshed. If the fastening assembly needs to be fastened more loosely, the saw teeth on the outer side of the multi-stage saw teeth can be meshed, thereby achieving fine adjustment of the tightness of the fastening.

[0046] In some embodiments, the female joint component may further include a first hinge portion 1012 and a second hinge portion 1013. The first hinge portion 1012 and the second hinge portion 1013 are rotatably coupled to each other through a hinge shaft 1014, thereby defining an insertion hole therebetween for inserting the external insertion portion 1023. The hinge shaft 1014 may be disposed at one end of the insertion opening of the first hinge portion 1012 and the second hinge portion 1013 adjacent to the insertion hole.

[0047] In some embodiments, the first mating structure 1011 can be arranged on the inner side of the first hinge portion 1012 toward the second hinge portion 1013, and the end of the first hinge portion 1012 away from the insertion opening is suitable for being driven to rotate around the hinge axis 1014 away from the second hinge portion 1013 to decouple the first mating structure 1011 from the second mating structure 1024, such as Figure 4 shown.

[0048] In this way, for example, when the user finishes riding and wants to remove the helmet, the user only needs to apply force to the end of the first hinge portion 1012 away from the insertion opening, so that the first hinge portion 1012 rotates around the hinge axis 1014 to decouple the first matching structure 1011 and the second matching structure 1024. In this way, the user can easily take off the helmet.

[0049] like Figure 3 and Figure 4 As shown, the detection assembly 103 is arranged in the internal accommodation space and includes a circuit board 1031 and a switch component 1032 coupled to the circuit board 1031. The switch component 1032 can be triggered after the external insertion portion 1023 is inserted into the insertion hole so that the first matching structure 1011 and the second matching structure 1024 are matched in place. The triggered switch component 1032 can continue to complete various subsequent operations.

[0050] For example, in some embodiments, the detection component 103 may further include a control component 1033 and a communication component. The control component 1033 and the communication component are also arranged on the circuit board 1031 and coupled to the switch component 1032. When the switch component 1032 is triggered, the control component 1033 can generate a matching signal. The communication component is coupled to the control component 1033 and can send the matching signal to an external device.

[0051] Taking the buckle assembly on the motorcycle helmet as an example, when the user puts on the helmet and buckles the buckle assembly, the switch component 1032 will be triggered, so that the communication component will send a matching signal to the motorcycle central control component or the helmet lock component. After receiving the matching signal, the motorcycle central control component will determine that the user has put on the helmet, and can allow the user to start the motorcycle to ride, thereby improving safety.

[0052] In some embodiments, the communication component can use any appropriate near field communication means to send the matching signal to the external device. For example, available near field communication devices include but are not limited to Bluetooth, near field communication (NFC), radio frequency identification (RFID), and Zigbee. For example, Bluetooth transmission has the advantages of low power consumption, high security, and ease of use. The communication component of the embodiment of the present disclosure can use Bluetooth transmission mode to transmit the above data.

[0053] According to the snap-fit ​​assembly of the embodiment of the present disclosure, a built-in battery 1034 can be used to power the switch component 1032, the control component 1033 and the communication component. The battery 1034 can be, for example, a button battery, which is arranged in the internal accommodation space and is electrically connected to the switch component 1032, the control component 1033 and the communication component, so as to power these components. In order to save space, the battery 1034 and the circuit board 1031 and the components thereon are arranged overlapping. In order to avoid collision between the battery 1034 and the components on the circuit board 1031 and / or to improve the insulation performance, a shock-absorbing insulating pad 1035 is arranged between the battery 1034 and the circuit board 1031. In some embodiments, the shock-absorbing insulating pad 1035 can be made of a flexible insulating material such as rubber, silicone or sponge pad.

[0054] As long as it can be triggered after the first matching structure 1011 and the second matching structure 1024 are matched in place, the switch component 1032 according to the embodiment of the present disclosure can be made of any appropriate electronic device. For example, the switch component 1032 can be but not limited to a Hall switch, a reed switch or a mechanical switch. A Hall switch is a sensor made using the Hall effect, which can detect the magnitude of a magnetic field, and the change in its output reflects the magnetic field or the relative change of the magnetic field. For example, a high level is output when a magnetic field exists, and a low level is output when a magnetic field does not exist. This principle can be used to achieve the effect of being triggered (for example, providing a high level) after the first matching structure 1011 and the second matching structure 1024 are matched in place, which will be further explained below. A reed switch is a switch composed of two magnetic reeds sealed in a glass tube. When the magnetic field approaches the reed switch, the reed will be magnetized and attracted, thereby closing the switch. When the magnetic field is removed, the reed will be disconnected, thereby opening the switch.

[0055] A mechanical switch is a switch that uses mechanical movement to control the on and off of a circuit, and may include a trigger portion. For example, after the male plug component 102 is inserted into the female plug component 101 and the first mating structure 1011 and the second mating structure 1024 are mated in place, the female plug component 101 can push against the trigger portion and trigger the mechanical switch.

[0056] It can be seen that the three switches mentioned above can utilize the mutual movement between the male plug component 102 and the female plug component 101 to complete the triggering of the switch component 1032. For the Hall switch and the reed switch, it is also necessary to use an external magnetic field. The following will mainly take the switch component 1032 as an example to describe the concept according to the present disclosure. It should be understood that the case where the switch component 1032 belongs to any other appropriate switch component 1032 is also similar, and will not be repeated in detail below.

[0057] In the embodiment where the switch component 1032 includes a Hall switch or a reed switch, the magnetic component 104 for providing a magnetic field can be arranged on the female plug component 101. The magnetic component 104 can trigger the Hall switch or the reed switch after the first matching structure 1011 and the second matching structure 1024 are matched in place. Taking the Hall switch as an example, as long as it can be triggered after the first matching structure 1011 and the second matching structure 1024 are matched in place, the Hall switch and the corresponding magnetic component 104 can be arranged in any appropriate position.

[0058] For example, Figures 1 to 4 The magnetic component 104 is shown to be arranged outside the insertion opening of the insertion hole of the female plug component 101. Correspondingly, the Hall switch is arranged at one end of the circuit board 1031 adjacent to the female plug component 101. Figures 1 to 4 In the illustrated embodiment, since the magnetic component 104 is arranged outside the insertion opening, it is not necessary to arrange the Hall switch at an internal position corresponding to the external insertion portion 1023. Therefore, the circuit board 1031 can be arranged more compactly, and the size of the snap-fit ​​assembly can be further reduced by overlapping the circuit board 1031 and the battery 1034.

[0059] Figures 5 to 10 1024 is a schematic diagram showing another arrangement of the snap-fit ​​assembly, in which the magnetic component 104 is arranged in the hole wall of the insertion hole. Correspondingly, the Hall switch can be arranged at a position where it can be triggered by the magnetic field of the magnetic component 104 after the first matching structure 1011 and the second matching structure 1024 are matched in place, that is, arranged at an internal position corresponding to the external insertion portion 1023, such as Figure 8 and Fig. 9 In this way, when the external insertion part 1023 is inserted into the insertion hole, the Hall switch can be triggered by the magnetic component 104 inside the hole wall of the insertion hole, so that the control component 1033 generates a matching signal and is sent out by the communication component.

[0060] As mentioned above, Figures 5 to 10 The external insertion portion 1023 shown is formed by the first housing 1021 and the second housing 1022 being buckled together. The second mating portion 1024 is formed on the first housing 1021 and is located on a side away from the second housing 1022. This method can make the circuit board larger, thereby facilitating the arrangement of more components.

[0061] In some embodiments, the Hall switch may be a unipolar Hall switch. A unipolar Hall switch is a Hall switch that is sensitive to only one magnetic pole (N pole or S pole), and has the advantages of low cost, low power consumption, small size, strong anti-interference ability, and high reliability. By using a unipolar Hall switch, the cost can be reduced while reducing the risk of false triggering, thereby improving reliability.

[0062] To facilitate the assembly of internal electronic components, in some embodiments, the first housing 1021 and the second housing 1022 of the male plug component 102 may be connected to each other by fasteners 105, snap connections, bonding, or interference fit. Figure 3 and Figure 8 In the illustrated embodiment, the first housing 1021 and the second housing 1022 may be coupled to each other via a fastener 105 such as a screw.

[0063] In some embodiments, the male plug component 102 may further include a battery stop 1028, such as Figure 7 As shown. The battery limiting portion 1028 is arranged on the second shell 1022 and extends toward the internal accommodation space to limit the position of the battery 1034. The battery 1034 accommodation portion may include protrusions with an arc-shaped cross-section arranged in the circumferential direction. Every two protrusions are arranged at a certain distance, so that the multiple protrusions form an annular structure that limits the battery 1034. The diameter of the annular structure corresponds to the diameter of the battery 1034, so that the battery 1034 can be placed and confined therein. A hook may be provided at the free end of at least some of the multiple protrusions to limit the movement of the battery 1034 and prevent the battery 1034 from falling out.

[0064] Return to reference Figure 2 and Figure 3 In some embodiments, in order to improve the appearance and safety performance and prevent users from disassembling at will, in some embodiments, the male plug component 102 may further include a cover plate 1027, which is arranged on the side of the second housing 1022 away from the first housing 1021. After the first housing 1021 and the second housing 1022 are assembled, the screw holes may be covered by the cover plate 1027, thereby improving the appearance and preventing users from disassembling at will. The cover plate 1027 may be made of glass, acrylic plate, plastic plate, metal plate or any other double materials.

[0065] In order to improve the waterproof and dustproof performance of the male plug component 102, thereby preventing water and dust from affecting the internal electronic components, in some embodiments, the male plug component 102 may further include a sealing ring groove 1025 and a sealing ring 1026 arranged in the sealing ring groove 1025. The sealing ring groove 1025 is arranged on at least one of the first housing 1021 and the second housing 1022, and surrounds the internal accommodation space. Figure 3 and Figure 8 In the illustrated embodiment, a sealing ring groove 1025 is disposed in the first housing 1021. A sealing ring 1026 is disposed in the sealing ring groove 1025 to provide sealing after the first housing 1021 and the second housing 1022 are fastened together.

[0066] In order to facilitate the connection between the buckle assembly and the lanyard, in some embodiments, the buckle assembly may further include a first lanyard connection portion 106 arranged on the male plug component 102 and a second lanyard connection portion 107 arranged on the female plug component 101. The first lanyard connection portion 106 is arranged on at least one of the first shell 1021 and the second shell 1022, and is used for coupling the lanyard with the male connector component. For example, the first lanyard connection portion 106 may be a structure integrally formed with the first shell 1021. For example, Figure 3 and Figure 4 As shown, the end of the first housing 1021 away from the external insertion portion 1023 may have a lanyard groove 1062 and a hook rod 1061 integrally formed in the lanyard groove 1062. The hook rod 1061 divides the lanyard groove 1062 into two parts. When a lanyard needs to be connected, the free end of the lanyard passes through one part of the lanyard groove 1062 and passes out from the other part of the lanyard groove 1062 and is finally fixed to the appropriate position of the lanyard by an appropriate method. In some embodiments, an anti-slip portion may be included on the hook rod 1061 to prevent the lanyard from sliding thereon and causing it to loosen.

[0067] The second lanyard connection portion 107 is arranged on the female connector part for coupling the lanyard with the female connector part. The second lanyard connection portion 107 may adopt a single slot structure, such as Figure 2 and Figure 3 As shown, it is only necessary to allow the other free end of the lanyard to pass through. The free end of the lanyard passing through the second lanyard connecting portion 107 can be connected to other positions of the lanyard in an appropriate manner, thereby completing the connection between the lanyard and the female connector component.

[0068] In some embodiments, Fig.10 As shown, the first lanyard connection part 106 may also be a hooking rod 1061 detachably arranged on the first housing 1021. When the lanyard needs to be connected, it is only necessary to place the lanyard perforation of one end of the lanyard that has been knotted or sewn into the lanyard groove 1062 of the first housing 1021. Then, the first lanyard connection part 106 passes through the through hole on the wall of the lanyard groove 1062 and through the lanyard perforation to reach the side wall on the other side of the lanyard groove 1062. A threaded hole may be provided on the side wall on the other side, which can be coupled therein by the threaded part formed on one side of the hooking rod 1061, thereby completing the connection between the lanyard and the male plug component 102.

[0069] An operating part may be provided at the other end of the hook rod 1061 away from the threaded part. The operating part can be operated by a user through a tool such as a screwdriver, and is conducive to screwing the threaded part of the first hanging rope connection part 106 into the threaded hole, thereby completing the coupling between the first hanging rope connection part 106 and the first shell 1021.
