[0035] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, high, low, top, bottom" generally refer to the position of the corresponding component or structure in the direction of gravity. Figure 1The directions of the drawings shown. "Inside and outside" refer to the inside and outside of the corresponding component outline. In addition, it should be noted that the terms used, such as "first, second", etc., are to distinguish one element from another and have no order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0037] For ease of understanding, please refer to the attached Figures 1 to 7 , the specific structure and working principle of the helmet strap disclosed in the present invention are explained in detail with reference to the embodiments.

[0038] The inventor of the present application found that the reason why users are unwilling to wear helmets properly, i.e., not inserting the male and female buckles in the buckle, is that the male buckle in the related art has a locking portion on only one side that locks with the locking portion of the female buckle, i.e., the male buckle can only be locked by inserting it into the female buckle in a specific direction, and the locking cannot be completed if it is inserted in the wrong direction, resulting in misoperation. This greatly increases the complexity of the user's operation, which is also an important factor in the user's unwillingness to wear helmets properly.

[0039] To this end, the present disclosure relates to a buckle for a helmet, which can be applied to various helmets, so that the helmet using the buckle of the present disclosure can be easily worn and can help the user detect whether the helmet is worn correctly. Figure 1 and Figure 2 The helmet buckle disclosed in the present invention includes a male buckle 1 and a female buckle 2, wherein the male buckle 1 includes a first connecting end 11 and a first plug-in end 12, the first connecting end 11 is used to connect the male buckle 1 to the helmet, and the connection method can be to wrap the strap on the helmet around the first connecting end 11 of the male buckle 1 to complete the fixation, the first plug-in end 12 includes a plug 121 and a first clamping portion 122 arranged on a first side surface of the plug 121 and a second clamping portion 124 arranged on a second side surface opposite to the first side surface, through the plug 121, the first clamping portion 122 and the second clamping portion 124, the first plug-in end 12 can cooperate with the female buckle 2 to fix the male buckle 1 on the female buckle 2.

[0040] The female buckle 2 includes a second connecting end 21 and a second plug-in end 22. The second connecting end 21 is used to connect the female buckle 2 to the helmet. The connection method can be the same as that of the male buckle 1. The fixation is completed by wrapping the strap on the helmet around the second connecting end 21 of the female buckle 2. The second plug-in end 22 includes a slot 221 for inserting the plug 121 and a locking portion 222 that can be selectively locked with the first clamping portion 122 or the second clamping portion 124.

[0041] The buckle disclosed in the present invention is provided with a snap-on portion, namely a first snap-on portion 122 and a second snap-on portion 124, on the first and second sides opposite to the plug 121 of the male buckle 1, and the locking portion 22 of the female buckle 2 can selectively lock with any one of the snap-on portions. Therefore, no matter in which direction the user plugs the male buckle 1 and the female buckle 2, the locking portion 222 can lock with one of the snap-on portions, thereby avoiding the cumbersome operation caused by misoperation. The user experience is improved and the possibility of the user wearing the helmet in a standardized manner is improved, and the safety is better. Especially in emerging fields such as shared electric motorcycles, user experience that facilitates user operation is more important.

[0042] Specifically, when the male buckle 1 and the female buckle 2 need to be fixedly connected, the user only needs to hold the male buckle 1, insert the plug 121 on the male buckle 1 into the slot 221 of the female buckle 2, and make the first clamping part 122 or the second clamping part 124 on the plug 121 cooperate with the locking part 222 in the slot 221, so as to complete the fixed connection between the male buckle 1 and the female buckle 2. Since the first clamping part 122 and the second clamping part 124 are respectively provided on the first side and the second side of the plug 121, when the user inserts the male buckle 1 and the female buckle 2, the plug 121 and the locking part 222 can be matched and fixed, so that the connection of the buckle can be more convenient, the installation time can be saved, and the user's experience can be improved.

[0043] In one embodiment of the present disclosure, see Figure 2 and Figure 4 The first clamping portion 122 and the second clamping portion 124 include a plurality of first clamping teeth 123 arranged along the insertion direction, and the first clamping portion 122 and the second clamping portion 124 are symmetrically arranged. In order to facilitate the mutual cooperation with the first clamping teeth 123, in this embodiment, see Figure 2 and Figure 5 The locking portion 222 includes a mounting end and an operating end, and a second latching tooth 223 is further provided between the mounting end and the operating end. The second latching tooth 223 faces the slot 221, and the second latching tooth 223 can be mutually locked with the first latching tooth 123 on the first latching portion 122 or the second latching portion 124 to complete the fixed connection between the male buckle 1 and the female buckle 2. The fixed connection between the male buckle 1 and the female buckle 2 is completed by providing the first latching tooth 123 and the second latching tooth 223, which can have good stability and is not easy to cause the male buckle 1 and the female buckle 2 to be separated, and the structures of the first latching tooth 123 and the second latching tooth 223 are also relatively simple, which is convenient for processing.

[0044] In order to facilitate the disassembly between the male buckle 1 and the female buckle 2, the mounting end can be rotatably connected to the slot 221, and an operating space is formed between the operating end and the slot 221. When the male buckle 1 and the female buckle 2 need to be disassembled, the user only needs to put his hand into the operating space and rotate the locking part 222 to remove the male buckle 1 from the female buckle 2. Since the first side surface and the second side surface of the plug 121 are respectively provided with the first clamping part 122 and the second clamping part 124, the mounting space formed by the buckle of the present disclosure is larger, so that the user's operation can be more convenient. Figure 2 The mounting end of the locking portion 222 and the slot 221 can be rotatably connected via a rotating shaft and an ear plate 25 disposed on the female buckle 1, and a torsion spring can also be disposed on the rotating shaft to ensure the stability of the connection between the male buckle 1 and the female buckle 2, and to allow the locking portion 222 to automatically rebound after disassembly is completed.

[0045] In some emerging fields, such as the management of shared electric motorcycles or takeaway riders, it is usually necessary to monitor whether the user strives to wear a helmet. Therefore, the helmet buckle provided by the male buckle also includes a detection device 3, which is arranged on at least one of the male buckle 1 and the female buckle 2, or the detection device 3 can be arranged on both the male buckle 1 and the female buckle 2. The detection device 3 can detect whether the position of the user wearing the helmet is correct, whether the helmet is worn securely, etc., so as to improve the safety of the user after wearing the helmet, and avoid the occurrence of safety accidents caused by problems such as incorrect helmet wearing position or unreliable wearing. The detection device 3 can be various different sensors, which detect whether the buckle is worn securely and whether the connection is stable through the sensor, or it can also be some clamping structures, and only the correct wearing position can fix the male buckle 1 and the female buckle 2. Of course, in other embodiments, the detection device 3 can also be other types of mechanisms, as long as it can play a detection role, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0046] In one embodiment of the present disclosure, see Figure 6 and Figure 7 The detection device 3 includes a base 31 and a circuit board 32, a detection member 33 and a battery 34 arranged on the base 31. The detection member 33 is used to detect relevant parameters when the user wears the helmet to remind the user to wear the helmet correctly. In order to ensure that the circuit board 32 and the detection member 33 can be powered and work normally, in this embodiment, the detection member 33 and the battery 34 are electrically connected to the circuit board 32 respectively, so that the circuit board 32 and the detection member 33 are powered by the battery 34. The electrical connection method can be connected by wires, or by metal contacts, etc., as well as other electrical connection methods known to those skilled in the art, which will not be described in detail here.

[0047] In one embodiment of the present disclosure, see Figure 6 and Figure 7 The detection member 33 includes a first detection member 331 and a second detection member 332. The first detection member 331 and the second detection member 332 can respectively detect parameters of different users wearing the helmet, so as to more accurately prompt the user to wear the helmet correctly. The first detection member 331 and the second detection member 332 can be used separately and set only on one of the male buckle 1 or the female buckle 2, or they can be used together and set on the male buckle 1 and the female buckle 2 respectively.

[0048] In this embodiment, the first detection member 331 is a Hall sensor, and the detection device 3 also includes a sensing member 39. The Hall sensor and the sensing member 39 can be respectively arranged on the male buckle 1 and the female buckle 2. The position of the sensing member 39 can be detected by the Hall sensor to determine whether the male buckle 1 and the female buckle 2 are locked in place. The second detection member 332 is a capacitive sensor, which can detect whether the buckle fits the skin and judge whether the buckle is worn correctly. Of course, in other embodiments, the detection device 3 can also include other detection components, and the first detection member 331 and the second detection member 332 can also be other types of sensors, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0049] In one embodiment of the present disclosure, see Figure 4 , the sensing member 39 is a magnetic member, which is arranged on the first side or the second side of the plug 121, and the Hall sensor is located on the female buckle 2. In this embodiment, a mounting groove 13 is arranged on the second side of the plug 121 of the male buckle 1, and the magnetic member is located in the mounting groove 13. A cover plate 14 is arranged at the opening of the mounting groove 13, and the mounting groove 13 can be sealed by the cover plate 14 to ensure the stability of the magnetic member located therein. The sealing method can be fixed by bonding or detachably connected by threads, which will not be described in detail here. When the male buckle 1 is correctly inserted into the female buckle 2, the magnetic member located in the plug 121 will be in the correct position. After the Hall sensor located in the female buckle 2 detects the position of the magnetic member, it will be concluded that the male buckle 1 and the female buckle 2 have been locked in place, otherwise it will be concluded that they are not locked in place, and the user will be prompted to re-lock, etc.

[0050] In one embodiment of the present disclosure, the detection device 3 may further include an alarm component, which may be a buzzer or a flash light, etc., which can remind the user that the helmet is not worn correctly. By setting the alarm component, when the first detection member 331 and the second detection member 332 detect that the user is not wearing the helmet correctly, an alarm is issued to promptly remind the user that the helmet is not worn correctly, so that the user can wear the helmet correctly again after receiving the alarm, thereby improving the safety of the user when using the helmet and avoiding accidents.

[0051] In one embodiment of the present disclosure, see 5 and Figure 6 , the base 31 is located in the female buckle 2, and a receiving cavity 24 with a socket 23 is provided on the female buckle 2. The base 31 can be inserted into the installation cavity 24 through the socket 23 and can be detachably fixedly connected to the female buckle 2, so that the battery replacement and maintenance of the detection device 3 on the base 31 can be easily realized, which is more important for the fields where helmets such as shared electric motorcycles need to be frequently used. In this embodiment, an end plate 313 is provided on the base 31, and a step groove is provided at the socket 23 of the installation cavity 24. When the base 31 is inserted into the installation cavity 24 through the socket 23, the end plate 313 of the base 31 can be clamped at the step groove on the installation cavity 24, thereby completing the detachable fixed connection between the base 31 and the female buckle 2. Of course, in other embodiments, the base 31 can also be detachably fixedly connected to the female buckle 2 in other ways, or the base 31 is set on the male buckle 1. The specific method can be determined according to the actual situation, and the present disclosure does not limit this.

[0052] In one embodiment of the present disclosure, see 5 and Figure 6 The end plate 313 of the base 31 and the step groove of the installation cavity 24 are both provided with fastening holes 315. When the end plate 313 of the base 31 is clamped on the step groove, the base 31 can be detachably fixedly connected to the socket 23 by the first fastener 316. The fastening hole 315 and the first fastener 316 can be threaded holes and bolts. When the base 31 is fixedly connected, it is only necessary to insert the bolts into the threaded holes on the end plate 313 and the step groove, and then rotate to complete the installation.

[0053] In order to ensure the sealing of the connection and prevent rainwater or sweat from penetrating into the installation cavity 24, a sealing ring 314 is also provided on the end plate 313 of the base 31. The sealing ring 314 is made of a flexible material, such as rubber, resin, etc. The sealing ring 314 can be integrally formed on the end plate 313, or can be separately detachably provided. When the base 31 is fixedly connected to the socket 23, the sealing ring 314 can seal the socket 23 to prevent liquid from penetrating into the installation cavity 24, and protect the safety of the detection member 33, the battery 34, etc., especially in the shared field that is often exposed outdoors, the sealing is more important.

[0054] In one embodiment of the present disclosure, see Figure 6 and Figure 7A battery receiving groove 311 is provided on the base 31, and the battery 34 is detachably connected to the battery receiving groove 311, and is electrically connected to the circuit board 32 through an electrical connector 35. The battery receiving groove 311 can ensure the stability of the battery 34 in the base 31, and prevent the battery 34 from detaching from the base 31 during the use of the helmet, causing the detection device 3 to fail. In this embodiment, the battery receiving groove 311 includes a plurality of arc-shaped protrusions 312, and adjacent arc-shaped protrusions 312 are arranged at intervals to form a circular battery receiving groove 311, and the diameter of the arc-shaped protrusion 312 can be set to a value that is slightly different from the diameter of the battery 34. When the battery 34 is placed in the battery receiving groove 311, the arc-shaped protrusion 312 can squeeze the battery 34 inward to a certain extent, thereby further increasing the stability of the battery 34 in the battery receiving groove 311. Of course, in other embodiments, other structures can also be provided on the base 31 to fix the battery 34, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0055] In addition, in this embodiment, the battery 34 is detachably connected to the battery receiving slot 311, that is, the battery 34 can be replaced, which is more important in frequently used shared areas. The interval between adjacent arc-shaped protrusions 312 can facilitate the removal of the battery in the battery receiving slot 311 for operation when replacing the battery.

[0056] In one embodiment of the present disclosure, see Figure 6 and Figure 7 The electrical connector 35 includes a first spring 351 and a second spring 352 respectively connected to the circuit board 32. The first spring 351 is located at the bottom of the receiving groove 311, and the second spring 352 is located above the first spring 351, and a gap is formed between the first spring 351 and the second spring 352. When installing the battery 34, it is only necessary to place the battery 34 in the gap formed between the first spring 351 and the second spring 352, and the first spring 351 and the second spring 352 can clamp the battery 34 in the battery receiving groove 311. The installation of the battery 34 by the first spring 351 and the second spring 352 can make it more convenient to replace the battery 34, and it is only necessary to operate the elastic deformation of the second spring 352 and directly drag the battery 34. In addition, the first spring 351 and the second spring 352 can further prevent the battery 34 from moving in the base 31, thereby improving the stability of the battery 34 in the battery receiving groove 311.

[0057] In another embodiment of the present disclosure, see Figure 6 and Figure 7The circuit board 32 is provided with a first plug-in terminal 36, the battery 34 is located in the battery receiving slot 311, and is electrically connected to the first plug-in terminal 36 through the second plug-in terminal 37, so as to electrically connect the battery 34 to the circuit board 32. In this embodiment, see Figure 3 The second plug-in terminal 37 is electrically connected to the positive and negative electrodes of the battery 34 through the first wiring harness 361 and the second wiring harness 362 respectively, and a buffer pad 38 is also provided on the side of the battery 34 away from the battery receiving groove 311. Since there is no separate restriction in the axial direction of the battery 34, but when the base 31 needs to be inserted into the receiving cavity 24, the battery 34 is limited by the inner wall of the receiving cavity 24. Therefore, the buffer pad 38 can prevent the battery 34 from directly contacting the inner wall of the receiving cavity 24 and causing friction or noise, which is more important for user experience in the sharing field.

[0058] In some other embodiments of the present disclosure, the second plug-in terminal 37 can also be configured to be clamped on the first plug-in terminal 36, so as to prevent the first plug-in terminal 36 and the second plug-in terminal 37 from being disengaged when the buckle of the helmet shakes due to external environmental factors. After the first plug-in terminal 36 is clamped in the second plug-in terminal 37, the electrical connection between the battery 34 and the circuit board 32 can continue to be maintained when the battery 34 is disengaged from the battery receiving slot 311, thereby preventing the detection device 3 from malfunctioning.

[0059] In some fields, especially in the field of sharing, the length of the helmet straps needs to be adjusted for different people to be suitable. In the related art, only the length of the straps can be adjusted, which is inconvenient to operate and poorly adaptable to different groups. In one embodiment of the present disclosure, see Figure 1 and Figure 2 A lace installation groove 4 is formed on the first connection end 11 and / or the second connection end 21, and a lace anti-slip shaft 41 is detachably installed in the lace installation groove 4. The lace on the helmet can be wound and fastened to the male buckle 1 and / or the female buckle 2 through the lace anti-slip shaft 41. In this way, in addition to adjusting the length of the lace itself, the laces of different lengths can be replaced by removing the lace installation groove to meet the needs of different user groups.

[0060] Specifically, a plurality of spike-shaped protrusions are provided on the strap anti-slip shaft 41. The strap of the helmet is usually made of cloth. The spike-shaped protrusions can lock the strap on the strap anti-slip shaft 41, thereby improving the stability of the connection between the male buckle 1 and the female buckle 2 and the helmet. Of course, in other embodiments, other anti-slip fastening structures can also be provided on the strap anti-slip shaft 41, such as increasing the friction between the strap anti-slip shaft 41 and the strap by providing a rubber layer, or protrusions of other shapes, etc., which will not be described in detail here.

[0061] In one embodiment of the present disclosure, see Figure 1and Figure 2 A mounting hole 42 is formed on the side wall of the lace installation groove 4, and the lace anti-slip shaft 41 has an axial through hole. When the lace anti-slip shaft 41 needs to be installed in the lace installation groove 4, the second fastener 43 can pass through the through hole on the lace anti-slip shaft 41 and cooperate with the mounting hole 42 on the lace installation groove 4 to fix the lace anti-slip shaft 41 in the lace installation groove 4. In this embodiment, see Figure 2 The second fastener 43 can be a bolt, such as a quick-release bolt, and a nut that can cooperate with the bolt can be provided in the mounting hole 42. When it is necessary to fix the lace anti-slip shaft 41 in the lace mounting groove 4, it is only necessary to pass the bolt through the through hole on the lace anti-slip shaft 41 and cooperate with the nut in the mounting hole 42 to detachably fix the lace anti-slip shaft 41 in the lace mounting groove 4.

[0062] When the helmet buckle of the present disclosure is used, the battery 34 on the detection device 3 needs to be installed first. The installation process is to put the battery 34 into the battery receiving slot 311 on the base 31, and then connect the first plug terminal 36 on the battery 34 with the second plug terminal 37 on the circuit board 32 to complete the installation of the battery 34. Then, the base 31 is inserted into the installation cavity 24 through the socket 23 on the female buckle 2. After the end plate 313 on the base 31 is clamped in the installation cavity 24, the base 31 is fixedly connected to the female buckle 2 through the first fastener 316, and finally the sensor 39 is installed on the male buckle 1 to complete the assembly of the buckle.

[0063] After the assembly is completed, the male buckle 1 and the female buckle 2 need to be connected to the laces on the helmet respectively. The installation process is to wrap the laces on the helmet around the lace anti-slip shaft 41 on the lace installation groove 4. After the installation is completed, since the first locking teeth 123 are provided on the opposite sides of the plug 121 on the male buckle 1, they can be locked with the second locking teeth 223 in the female buckle 2. When the user wears the helmet, it is more convenient to lock the male buckle 1 and the female buckle 2 together, thereby improving the user experience.

[0064] In addition, the detection device 3 and the sensor 39 on the male buckle 1 and the female buckle 2 can also detect whether the user wears the helmet correctly. When the first latch 123 on the male buckle 1 is not locked in place with the second latch 223 on the female buckle 2, the first detection member 331 can detect the position of the sensor 39 to remind the user that the male buckle 1 and the female buckle 2 are not locked in place and need to be locked again. The second detection member 332 can detect whether the female buckle 2 fits the skin. If not, it will also remind the user to lock it again to ensure that the user can wear the helmet correctly, improve the safety of the user when using the helmet, and avoid accidents.

[0065] According to the second aspect of the present disclosure, a helmet is also provided, comprising a helmet body, a strap, and the buckle described in the above embodiment. The buckle can be fixedly connected to the helmet through the strap on the helmet body, so that the user can more conveniently complete the connection between the male buckle 1 and the female buckle 2, and can also play a role in detecting whether the user wears the helmet correctly, ensuring the safety of the user when using the helmet and avoiding accidents. In this embodiment, the structure, connection relationship, positional relationship of the buckle components, and the working states of the male buckle 1, the female buckle 2, and the detection device 3 when in use are the same as the buckle in the above description of the present disclosure, and will not be repeated here.

[0066] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
