[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0038] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] Reference Figures 1a-1h As shown, according to one embodiment of this application, a helmet device 1 is provided, the helmet device 1 being applied to a vehicle, the helmet device 1 including a storage frame 10 and a lock 11, the storage frame 10 being mounted on the vehicle body of the vehicle; the storage frame 10 having a receiving cavity for storing the helmet body;

[0041] The lock 11 includes a latch 111 and a drive mechanism 112. The drive mechanism 112 is installed on the side of the storage frame 10 opposite to the receiving cavity. The latch 111 is connected to the drive mechanism 112, and the drive mechanism 112 can drive the latch 111 to switch between an extended state and a retracted state. The latch 111 includes a locking bottom surface 1113, which is at least partially curved. In the extended state, the latch 111 extends into the receiving cavity and is located in the inner cavity of the helmet body, with the locking bottom surface 1113 abutting against the inner surface of the helmet body. In the retracted state, the latch 111 retracts from the receiving cavity.

[0042] The lock 11 is configured such that: when the latch 111 is in the retracted state, the helmet body can enter and exit the receiving cavity; when the latch 111 is in the extended state, the latch 111 can prevent the helmet body from leaving the receiving cavity.

[0043] The helmet device 1 provided in this application embodiment is applied to vehicles, particularly two-wheeled vehicles such as electric vehicles and motorcycles; it is especially suitable for shared two-wheeled vehicles. The helmet device 1 mainly includes a storage frame 10 and a lock 11. The storage frame 10 is installed on the vehicle body and has a receiving cavity for storing the helmet body 15. The lock 11 is installed on the storage frame 10 and includes a locking tongue 111 and a drive mechanism 112. The locking tongue 111 has an extended state and a retracted state. In the extended state, it is located in the receiving cavity; in the retracted state, it is out of the receiving cavity. When the helmet body 15 is stored in the receiving cavity, the locking tongue 111 is in the extended state and located inside the helmet body 15. The locking tongue 111 can prevent the helmet body 15 from leaving the receiving cavity, allowing the helmet device 1 to safely and stably store the helmet body 15.

[0044] Specifically, refer to Figure 1a As shown, in one embodiment, the storage frame 10 includes a base plate 101 and a surrounding plate 102, the base plate 101 and the surrounding plate 102 being connected to each other and enclosing to form the receiving cavity; the surrounding plate 102 has a shape adapted to the outer side of the helmet body, and the base plate 101 has a shape adapted to the opening of the helmet body;

[0045] The base plate 101 has a locking slot, through which the locking tongue 111 switches between an extended and retracted state. In the extended state, the locking tongue 111 is located within the inner cavity of the helmet body 15, engaging with the inner wall of the surrounding plate 102 to limit the helmet body 15 from both the inside and outside, ensuring that the helmet body does not move freely within the accommodating cavity, thus improving the stability and security of the helmet body during storage. Simultaneously, the extended state of the locking tongue 111 within the inner cavity of the helmet body protects it from external dust, impurities, rainwater, etc., preventing damage and malfunction of the lock 111; it also prevents the locking tongue 111 from being exposed and thus prevents forced unlocking, thereby improving the reliability and service life of the lock 11.

[0046] A locking opening on the base plate 101 allows the locking tongue 111 to enter and exit the receiving cavity, switching between an extended and retracted state. It is understood that when the helmet body is housed within the receiving cavity, the locking opening is located inside the helmet body; thus, the inner cavity of the helmet body protects the locking opening, preventing external dust, impurities, etc., from entering and preventing the locking tongue 111 from smoothly entering and exiting the receiving cavity; and also preventing rainwater from entering and damaging the electronic components inside the lock 11.

[0047] Furthermore, since the locking bottom surface 1113 of the locking tongue 111 is at least partially curved, it can better adapt to the shape changes of the inner surface of the helmet body when in contact with the inner surface of the helmet body, thereby improving the fit between the locking tongue 111 and the helmet body and enhancing the fixing effect of the locking tongue 111 on the helmet body.

[0048] Reference Figure 1b As shown, in one embodiment, the drive mechanism 112 includes a drive member and a transmission assembly, the drive member being connected to the transmission assembly, and the transmission assembly being connected to the locking tongue 111.

[0049] In this specific example, the driving force of the drive component is transmitted to the latch 111 through the transmission assembly, thereby driving the latch 111 to switch between the extended state and the retracted state.

[0050] Reference Figures 1c to 1gAs shown, in one embodiment, the driving component is a drive motor 1120; the transmission assembly includes a first worm 1121, a gear set, a second worm 1122, a gear shaft 1123, and an adapter wheel 1124. The output shaft of the drive motor 1120 is connected to the first worm 1121. Both the first worm 1121 and the second worm 1122 are connected to the gear set. The second worm 1122 also meshes with the gear shaft 1123. The gear shaft 1123 is coaxially connected to the adapter wheel 1124, and the adapter wheel 1124 is connected to the locking tongue 111 at its edge.

[0051] In this specific example, the output shaft of the drive motor 1120 rotates, thereby synchronously driving the first worm 1121 to rotate. The first worm 1121 then drives the gear set to rotate, which in turn drives the second worm 1122 to rotate. The second worm 1122 then drives the gear shaft 1123 meshing with it to rotate. The gear shaft 1123 then drives the adapter wheel 1124 to rotate, and finally the adapter wheel 1124 drives the locking tongue 111 to rotate to switch between the extended and retracted states.

[0052] The gear set not only transmits power between the drive motor 1120 and the locking tongue 111, but also reduces speed and increases torque. In addition, the direction of rotation can be changed by arranging the gear set reasonably according to actual needs.

[0053] Reference Figures 1c to 1g As shown, in one embodiment, the gear set includes a first gear 1125, a second gear 1126, a third gear 1127, a fourth gear 1128, and a fifth gear 1129. The first gear 1125 meshes with the first worm gear 1121, the second gear 1126 is coaxially connected to the first gear 1125, the third gear 1127 meshes with the second gear 1126, the fourth gear 1128 is coaxially connected to the third gear 1127, the fifth gear 1129 meshes with the fourth gear 1128, and the second worm gear 1122 is coaxially connected to the fifth gear 1129.

[0054] In this specific example, the first gear 1125 meshes with the first worm 1121, and their axes are perpendicular to each other. The second gear 1126 is coaxially connected to the first gear 1125; for example, the second gear 1126 and the first gear 1125 can be connected to each other by welding or bonding; or...

[0055] The second gear 1126 and the first gear 1125 can be a single unit. The third gear 1127 meshes with the second gear 1126, and their axes are parallel to each other. The fourth gear 1128 is coaxially connected to the third gear 1127. For example, matching sawtooth meshing structures can be provided on the end faces of the fourth gear 1128 and the third gear 1127 respectively, so that they mesh with each other at the end faces. The fifth gear 1129 meshes with the fourth gear 1128, and their axes are parallel to each other. The second worm 1122 and the fifth gear 1129 are coaxially connected. For example, the second worm 1122 and the fifth gear 1129 can be connected to each other by welding or bonding; or, the second worm 1122 and the fifth gear 1129 can be a single unit.

[0056] With the above structural design, the speed of the drive motor 1120 can be reduced while the torque of the drive motor 1120 can be increased; and the required rotation direction can be obtained while saving as much layout space as possible.

[0057] Furthermore, the drive motor 1120, the first worm gear 1121, the gear set, the second worm gear 1122 and the gear shaft 1123 are arranged inside the gearbox, and the adapter wheel 1124 is arranged outside the gearbox.

[0058] Reference Figures 1c to 1g As shown, in one embodiment, the adapter wheel 1124 includes a wheel body 11241 and a connecting post 11242. One end of the connecting post 11242 is disposed on the edge of the wheel body 11241, and the other end of the connecting post 11242 is connected to the locking tongue 111.

[0059] In addition, refer to Figure 1h As shown, in one embodiment, the latch 111 has a waist-shaped hole 1110, and the other end of the connecting post 11242 is inserted into the waist-shaped hole 1110.

[0060] In this specific example, the adapter wheel 1124 includes a wheel body 11241 and a connecting post 11242. One end of the connecting post 11242 is located at the edge of the wheel body 11241, that is, the connecting post 11242 is eccentrically positioned on the wheel body 11241. The other end of the connecting post 11242 is inserted into the oblong hole 1110 opened in the latch 111. When the wheel body 11241 rotates under the drive of the gear shaft 1123, the connecting post 11242 slides in the oblong hole 1110 and drives the latch 111 to rotate.

[0061] Reference Figures 1e to 1gAs shown, in one embodiment, the gear shaft 1123 has a protruding lug 11230; the helmet device includes a first switch 12 and a second switch 13, which are respectively disposed on both sides of the gear shaft 1123; the first switch 12 and the second switch 13 are configured such that: when the gear shaft 1123 rotates and drives the locking tongue 111 to the extended state through the adapter wheel 1124, the lug 11230 is linked to the first switch 12; when the gear shaft 1123 rotates and drives the locking tongue 111 to the retracted state through the adapter wheel 1124, the lug 11230 is linked to the second switch 13.

[0062] In this specific example, by providing a protruding lug 11230 on the gear shaft 1123, and by having the protruding lug 11230 cooperate with the first switch 12 and the second switch 13, the state of the latch 111 can be accurately fed back, thereby improving the reliability of the lock 11.

[0063] Furthermore, the gear shaft 1123 includes a first shaft segment and a second shaft segment arranged along the axial direction, wherein the first shaft segment is provided with a toothed structure that meshes with the second worm 1122; the second shaft segment is a smooth shaft segment and is provided with a protruding lug 11230.

[0064] Furthermore, the first switch 12 and the second switch 13 are mounted on the fixing plate 16.

[0065] Reference Figure 1h As shown, in one embodiment, the side of the latch 111 facing the receiving cavity is curved.

[0066] In this specific example, the side of the latch 111 facing the enclosure 102 is curved; for example, the side of the latch 111 facing the enclosure 102 includes alternating first arc segments 1111 and second arc segments 1112, wherein the first arc segment 1111 is convex and the second arc segment 1112 is concave. This special shape configuration helps to improve the structural strength of the latch 111.

[0067] Reference Figure 1a As shown, in one embodiment, the helmet device further includes an indicator light 14, which is disposed in the storage frame 10 and is signal-connected to the lock 11 to indicate the state of the latch 111.

[0068] In this specific example, the indicator light 14 can be used to indicate whether the lock 11 is locked after the helmet body 15 is placed into the receiving cavity of the storage frame 10. For example, if the lock 11 is not locked, the indicator light 14 flashes to provide a warning; or, if the lock 11 is locked, the indicator light 14 displays one color, and if the lock 11 is not locked, the indicator light 14 displays another color to provide a warning.

[0069] In one embodiment, the base plate 101 is provided with a signal recognizer for recognizing the helmet body; when the signal recognizer recognizes the helmet body, the locking tongue 111 switches from a retracted state to an extended state.

[0070] In this specific example, the base plate 101 is equipped with a signal recognizer for identifying the helmet body 15. When the signal recognizer identifies the helmet body 15, the locking tongue 111 switches from the retracted state to the extended state, thereby enabling the helmet device 1 to automatically lock the helmet body, improving ease of use. It also prevents the helmet body from failing to be secured due to misoperation or other reasons, thus improving the safety and reliability of helmet storage.

[0071] Alternatively, the signal reader can be, for example, an NFC antenna reader with a compatible NFC tag on the helmet body, so that the signal reader can accurately and effectively identify the helmet body.

[0072] Furthermore, before removing the helmet body 15 from the accommodating cavity, the unlocking operation is first performed through the mobile APP, so that the locking tongue 111 switches from the extended state to the retracted state, that is, the locking tongue 111 switches from the state in the accommodating cavity to the state of exiting the accommodating cavity, so that the locking tongue 111 will not block the helmet body 15 from entering and exiting the accommodating cavity.

[0073] In other embodiments, after the helmet body 15 enters the receiving cavity and is placed in place, a locking operation can be performed via a mobile APP, causing the locking tongue 111 to switch from the retracted state to the extended state, that is, the locking tongue 111 to switch from the state of exiting the receiving cavity to the state of being located in the receiving cavity, thereby locking the helmet body 15 to prevent the helmet body 15 from being easily removed.

[0074] According to yet another embodiment of this application, referring to Figure 2 As shown, a vehicle is provided, the vehicle including a helmet device 1 as described above, and a vehicle body 2, the helmet device 1 being mounted on the vehicle body 2.

[0075] The vehicle provided in this application embodiment includes the helmet device 1 and the vehicle body 2 described above. The helmet device 1 is installed near the front 21 of the vehicle body 2, making it convenient for the rider to store and retrieve the helmet body 15. The vehicle can be a two-wheeled vehicle such as an electric vehicle or a motorcycle, or other means of transportation that requires wearing a helmet.

[0076] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
