[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figures 1-4As shown, an embodiment of the present invention provides a quick-detachable brim structure, comprising a brim 1, a locking button 2, and a clamping seat 4. The brim 1 is connected to the helmet at both ends via a connector 11, which is disposed on the brim 1. In this embodiment, the connector 11 and the brim 1 are integrally formed by injection molding, and a first clamping platform 111 and a limiting groove 112 are disposed on the outer peripheral surface of the connector 11. The locking button 2 is passed through the connector 11, and an elastic member 3 is disposed between the locking button 2 and the connector 11. The locking button 2 can move along its axial direction, and an outer clamping portion 21 is disposed on the locking button 2, and a second clamping platform 2 is disposed on the outer side of the outer clamping portion 21. 11, the locking button 2 is passed through the connecting member 11, and the outer clamping portion 21 is limited in the limiting groove 112 so that there is no relative rotational movement between the connecting member 11 and the locking button 2; the clamping seat 4 is provided on the helmet, and the connecting member 11 is connected to the clamping seat 4 so that the brim 1 is connected to the helmet, and the clamping seat 4 is provided with a clamping groove 41, and a protrusion 42 is provided in the clamping groove 41, and a first notch 421 is provided at one end of the protrusion 42 facing the bottom of the clamping groove 41, and a second notch 422 is provided at the bottom end of the protrusion 42 facing the first notch 421. During installation, the locking button 2 is inserted into the connecting member 11 along its axial direction, and the elastic member 3 is arranged between the locking button 2 and the connecting member 11. The outer clamping portion 21 is limited in the limiting groove 112. The locking button 2 and the connecting member 11 are inserted into the clamping groove 41 at the same time. The locking button 2 and the connecting member 11 are rotated (it can be understood that the connecting member 11 drives the brim 1 to rotate at the same time when rotating) so that the first clamping platform 111 and the second clamping platform 211 are rotated into the first notch 421 at the same time. The first clamping platform 111 and the protruding portion 42 The bottom end of the second clamping platform 211 abuts against the second notch 422, and the second clamping platform 211 is limited in the second notch 422 under the action of the elastic member 3 to fix the locking button 2 and the connecting member 11 to the clamping seat 4; when disassembly is required, the locking button 2 is pressed to overcome the action of the elastic member 3 to drive the second clamping platform 211 to move away from the second notch 422 to disengage from the second notch 422, and then the locking button 2 and the connecting member 11 are rotated in the opposite direction to make the first clamping platform 111 and the second clamping platform 211 disengage from the first notch 421 so that the brim 1 and the helmet can be removed.

[0038] The quick-detachable brim structure ensures that the brim 1 is firmly connected to the helmet and is easy to disassemble. Disassembly can be achieved by simply pressing the locking button 2 and rotating it. The structure is simple and there is no risk of falling.

[0039] In this embodiment, the external clamping portion 21, the limiting groove 112, the first clamping platform 111, and the protrusion 42 are arranged in a one-to-one correspondence, and two are provided. The two external clamping portions 21 are symmetrically arranged, the two limiting grooves 112 are symmetrically arranged on the connecting member 11, the two first clamping platforms 111 are symmetrically arranged on the connecting member 11, and the two protrusions 42 are symmetrically distributed in the clamping groove 41. This structure makes the clamping more secure and the structure more reasonable.

[0040] Continue to refer to Figure 2 In order to limit the locking button 2 to the connecting member 11, the locking button 2 is further provided with an inner clamping portion 22, and the outer side surface of the inner clamping portion 22 is provided with a third clamping platform 221. The connecting member 11 is also provided with an inner clamping ring 113 connected to the inner side surface of the connecting member 11. When the locking button 2 is inserted into the connecting member 11, the inner clamping portion 22 can pass through the center hole of the inner clamping ring 113, and the third clamping platform 221 abuts against the bottom end of the inner clamping ring 113 to prevent the locking button 2 from detaching from the connecting member 11.

[0041] Along the axis of the inner clamping portion 22, the inner clamping portion 22 is provided with a third notch 222, which divides the inner clamping portion 22 into a first inner clamping portion and a second inner clamping portion spaced apart from each other. Two third clamping platforms 221 are provided, one on each of the first inner clamping portion and the second inner clamping portion. When the inner clamping portion 22 passes through the center hole of the inner snap ring 113, the first and second inner clamping portions approach each other. After the third clamping platform 221 passes through the inner snap ring 113, the first and second inner clamping portions naturally move apart, and the third clamping platform 221 forms a barb to prevent the locking button 2 from slipping out of the inner snap ring 113.

[0042] In other embodiments, the inner clamping portion 22 may also be made of a flexible material. During installation, the inner clamping portion 22 is deformed by squeezing to be inserted into the center hole of the inner clamping ring 113. After passing through the inner clamping ring 113, the inner clamping portion 22 naturally pops open, and the third clamping platform 221 is limited to the bottom end of the inner clamping ring 113.

[0043] In order to facilitate the third clamping platform 221 to pass through the center hole of the inner clamping ring 113 more smoothly, a chamfer is provided on the end of the third clamping platform 221 facing the clamping seat 4. The chamfer has a guiding function, making it easier for the third clamping platform 221 to enter the center hole of the inner clamping ring 113.

[0044] An end of the inner snap ring 113 away from the locking button 2 is provided with a clearance groove 1131 , and the third clamping platform 221 can be located in the clearance groove 1131 when clamped with the inner snap ring 113 so that the third clamping platform 221 does not interfere with other components.

[0045] The inner clamping part 22 and the outer clamping part 21 are coaxial and spaced apart. During installation, the inner clamping part 22 is passed through the center hole of the inner clamping ring 113, and the outer clamping part 21 is limited in the limiting groove 112 and abuts against the outer peripheral surface of the inner clamping ring 113, so that the structure is more reasonable.

[0046] Continue to refer to Figure 4In order to facilitate the second clamping platform 211 to enter the first notch 421 more smoothly, a first inclined surface 423 is provided at the bottom end of the entrance of the protrusion 42, and a second inclined surface 2111 is provided on the second clamping platform 211. When the connecting member 11 and the locking button 2 rotate toward the first notch 421 at the same time, the first inclined surface 423 slides and abuts against the second inclined surface 2111 to make the rotation smoother.

[0047] A boss 114 is provided at one end of the connecting member 11 connected to the brim 1. When the connecting member 11 is connected to the base 4, the base 4 abuts against the boss 114 to make the structure reasonable, and the end face of the boss 114 facing the base 4 is flat. When the base 4 and the connecting member 11 rotate relative to each other, the friction force is reduced.

[0048] In this embodiment, the elastic member 3 is a compression spring, which is sleeved on the inner clamping portion 22, with one end abutting against the locking button 2 and the other end abutting against the connecting member 11. The compression spring has a simple structure, is easy to use, and has low cost.

[0049] like Figures 1-6 , in this embodiment, during installation, the locking button 2 is first connected to the brim 1, and the outer clamping portion 21 is limited in the limiting groove 112, the third clamping platform 221 of the inner clamping portion 22 is clamped on the inner clamping ring 113, and the elastic member 3 is provided between the locking button 2 and the connecting member 11 to realize the elastic connection between the locking button 2 and the connecting member 11 along the axial direction of the connecting member 11; then the connected locking button 2 and the connecting member 11 are simultaneously installed on the card seat 4, the locking button 2 and the connecting member 11 are inserted into the card slot 41, and rotated toward the first notch 421 so that the first clamping platform 111 and the second clamping platform 211 are respectively clamped into the bottom end of the protruding portion 42 and the second notch 422, It is understood that the locking button 2 has the force to move in the direction away from the clamping seat 4 under the action of the elastic member 3. Therefore, the second clamping platform 211 can be limited in the second notch 422. At this time, after connection, the locking button 2 and the connecting member 11 cannot rotate in the second notch 422; when the brim 1 needs to be removed, the locking button 2 is manually pressed and the action of the elastic member 3 is overcome to make the second clamping platform 211 disengage from the second notch 422. At this time, the second notch 422 has no clamping relationship with the second clamping platform 211. The locking button 2 and the connecting member 11 are rotated in the opposite direction to make the first clamping platform 111 and the second clamping platform 211 rotate out of the first notch 421, thereby realizing the disassembly of the brim 1 and the helmet.

[0050] This embodiment also provides a helmet, which uses the above-mentioned quick-detachable brim structure to make it easier to disassemble the brim 1 from the helmet and ensure a firm connection.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
