[0016] In order to make the technical features and practical effects of the present invention fully comprehensible and to enable implementation according to the present invention, the present invention will be described in detail with reference to the preferred embodiments shown in the drawings.

[0017] 1 and 4, the present invention provides a foldable helmet 10, including a main body 11, a folding part 12, and a folding structure 13 and a rotating knob 14 provided between the main body 11 and the folding part 12. A first side 111 of the main body 11 is detachably coupled to a second side 121 of the folding part 12, and the folding part 12 can be selectively at least partially stored in the main body 11 via the folding structure 13 and the rotating knob 14, so that the foldable helmet 10 can be switched between a use state and a folded state.

[0018] The body portion 11 and the folding portion 12 are generally curved structures, and when the folding portion 12 is at least partially stored in the body portion 11, a convex surface of the folding portion 12 corresponds to a concave surface of the body portion 11.

[0019] In this embodiment, the foldable helmet 10 includes one main body portion 11 and two folding portions 12, and the two folding portions 12 are symmetrically installed on the two first side surfaces 111 located on opposite sides of the main body portion 11, and the two folding portions 12 form opposite side edges of the foldable helmet 10.

[0020] In the use state, the second side surface 121 of the folding part 12 is coupled to the first side surface 111 of the body part 11 in a concave-convex manner.

[0021] Preferably, a lock structure is formed between the first side surface 111 and the second side surface 121 to prevent unexpected separation between the main body portion 11 and the folding portion 12. For example, the first side surface 111 has an elastic piece extending toward the folding portion 12, a hook portion is formed at the end of the elastic piece, and the second side surface 121 has a hook groove recessed at a position corresponding to the elastic piece. In the process of combining the main body portion 11 and the folding portion 12, the elastic piece elastically deforms and returns to its original position until the hook portion is combined with the hook groove in a concave-convex manner, and the main body portion 11 can be firmly combined with the folding portion via the hook portion.

[0022] 1 and 2, in this embodiment, the locking structure may be a switch device that determines the coupling relationship between the main body portion 11 and the folding portion 12. For example, the first side surface 111 includes a rotation groove 112 and a protruding shaft 113, the rotation groove 112 is recessed in the first side surface 111, and an opening 1121 is formed by the rotation groove 112 and a part of the surface of the main body 11. The protruding shaft 113 extends from a bottom surface 1122 of the rotation groove 112 toward the folding portion 12, and the protruding shaft 113 includes a large diameter portion 1131 and a neck portion 1132. The large diameter portion 1131 is formed at an end of the protruding shaft, and the neck portion 1132 is formed between the large diameter portion 1131 and the bottom surface 1122. The second side surface 121 corresponds to the position of the rotation groove 112 and protrudes a position restricting rib 122 toward the first side surface 111. A gap 123 is defined between the position restriction rib 122 and the rotation groove 112 .

[0023] Furthermore, the first side surface 111 or the second side surface 121 includes at least one recess 1111, and when in the use state, the first side surface 111 and the second side surface 121 of the main body portion 11 and the folding portion 12 are coupled to each other, and the recess 1111 serves as a vent 124 to obtain the effects of ventilation and heat dissipation when worn. When the foldable helmet 10 is folded in advance, the vent 124 allows a user to insert a hand into the vent, making it easy to remove and separate the folding portion 12 from the main body portion 11.

[0024] In this embodiment, the first side 111 and the second side 121 are each recessed with one recess 1111, and when in the use state, the two recesses 1111 correspond to each other and jointly form the ventilation hole 124.

[0025] A rotating knob 14 is installed between the first side surface 111 and the second side surface 121, and the rotating knob 14 includes a rotating knob body 141 and a locking rib 143. The rotating knob body 141 is installed in the rotating groove 112 with the protruding shaft 113 as an axis. The rotating knob body 141 includes a toggle portion 142 corresponding to the opening 1121 of the rotating groove 112, and for example, the switching portion 142 is formed on the rough surface of the rotating knob body 141, and the user turns the rough surface through the opening 1121 to rotate the rotating knob body 141 with the protruding shaft 113 as an axis.

[0026] In this embodiment, the toggle portion 142 may be a lever that protrudes from the surface of the rotating knob body 141 and extends to the opening 1121 of the rotating groove 112, allowing the user to move the lever and rotate the rotating knob body 141 around the protruding shaft 113 as an axis.

[0027] The locking rib 143 is connected to the rotating knob body 141 and accommodated in the rotating groove 112. When the rotating knob body 141 rotates relative to the rotating groove 112 around the protruding shaft 113 as its axis, the locking rib 143 can selectively enter or exit the gap 123 according to the rotation direction of the rotating knob body 141. When the locking rib 143 enters the gap 123, the main body portion 11 and the folding portion 12 are locked and coupled to each other.

[0028] The folding structure 13 is formed between the main body portion 11 and the folding portion 12, connecting the main body portion 11 and the folding portion 12, and during the transformation process of the foldable helmet 10 between the use state and the folded state, the folding structure 13 can adjust the length of the folding structure 13 according to different states, in other words, the length of the folding structure 13 can be adjusted.

[0029] Referring to FIG. 1, this embodiment shows the foldable helmet 10 in use, the length of the folding structure 13 is a first length, the main body portion 11 and the folding portion 12 are close to each other, the first side 111 and the second side 121 are joined in a corresponding concave-convex manner, in other words, the main body portion 11 and the folding portion 12 are connected in a corresponding manner.

[0030] Referring to FIG. 4, this embodiment shows the folding helmet 10 in a folding process, in which the length of the folding structure 13 is a second length, the main body portion 11 and the folding portion 12 are separated from each other, and the folding structure 13 is adjusted to the maximum length of the folding structure 13, and the first side 111 and the second side 121 are separated, in other words, the folding portion 12 is installed at a distance from the main body portion 11.

[0031] Referring to Figure 5, this embodiment is the folded state of the foldable helmet 10, the length of the folding structure 13 is a third length, the folding portion 12 is accommodated within the main body portion 11, and the folding structure 13 is folded to the minimum length of the folding structure 13, and the first side 111 and the second side 121 are separated.

[0032] Here, the second length is greater than the first length, and the first length is greater than the third length.

[0033] Here, the folding structure 13 may be a linear object, which ensures that the angle between the main body portion 11 and the folding portion 12 is not restricted when the foldable helmet 10 is removed.

[0034] Preferably, the linear object is made of an elastic material, for example, an elastic body such as rubber or a spring.

[0035] Preferably, in this embodiment, when the foldable helmet 10 is in use, the linear object connecting the main body 11 and the folding part 12 is in a stretched state. Due to the elastic restoring force of the elastic material, during the folding process of the foldable helmet 10, the folding part 12 is quickly folded into the main body 11 by the elastic restoring force, and is not easily separated from the main body 11.

[0036] 4 and 5, the folding structure 13 may be a pivot structure, and the pivot structure includes a first pivot shaft 131, a second pivot shaft 132, a first connecting member 133 and a second connecting member .

[0037] Here, the first connecting member 133 and the second connecting member 134 are rod-shaped bodies.

[0038] Here, one end of the first pivot shaft 131 and the first connecting member 133 are pivotally attached to a part of the main body 11, and the first connecting member 133 is rotated relative to the main body 11 by the first pivot shaft 131. The second pivot shaft 132 is used to pivotally attach the first connecting member 133 and the second connecting member 134, and rotates the second connecting member 134 relative to the first connecting member 133 around the second pivot shaft 132.

[0039] Furthermore, the first connecting member 133 and the second connecting member 134 are provided with the first rail 1331 and the second rail 1341 penetrating therethrough along their length direction, respectively, to provide a sliding space for pivoting the second pivot shaft 132 of the first rail 1331 and the second rail 1341. In other words, when converting between the use state and the folded state, the second pivot shaft 132 can move to an optimal position of the first rail 1331 and the second rail 1341 by utilizing the sliding space.

[0040] Furthermore, in this embodiment, the folding structure 13 may include, but is not limited to, the second pivot axis 132 that pivotally connects the first connecting member 133 and the second connecting member 134; in other words, the folding structure 13 may include multiple second pivot axes 132 that pivotally connect multiple connecting members to improve the movable flexibility of removing the foldable helmet 10.

[0041] In summary, the foldable helmet 10 provided by the present invention can achieve the following advantages: 1. The main body portion 11 can be disassembled from the folding portion 12 by the folding structure 13 and the rotating knob 14, and can be folded inside the main body portion 11 to reduce the volume it occupies when stored. 2. By moving the rotating knob 14 backward toward the end of the folding portion 12 to lock it, it is possible to prevent the front end of the foldable helmet 10 from receiving an external force that causes the main body portion 11 and the folding portion 12 to loosen, thereby preventing the user's driving safety from being affected.
