[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Reference Figures 1 to 7 A motorcycle helmet lens mounting structure, comprising: a base 100, respectively fixedly mounted on both sides of a helmet body 200, comprising a base body 110, a locking mechanism 120 and a stopper 130, wherein the base body 110 is provided with an axis core 111 and an arc-shaped card slot 112, the stopper 130 is connected to the axis core 111 so that an installation gap 113 is formed between the stopper 130 and the base body 110, and a notch 114 is provided on a side wall of the arc-shaped card slot 112; the locking mechanism 120 is mounted on the The base 100 is used to limit the opening and closing of the gap 114; the lens 300 is provided with insertion ports 310 at both ends and a stop pin 320 on the inner wall; during installation, the locking mechanism 120 is opened, the insertion port 310 is inserted into the installation gap 113, and the stop pin 320 enters the arc groove 112 through the gap 114; when the locking mechanism 120 is closed, the lens 300 rotates around the axis core 111, and the stop pin 320 moves in the arc groove 112.

[0028] like Figure 1 and Figure 2 As shown, the bases 100 are fixedly mounted on both sides of the helmet body 200. Figure 3 and Figure 4 As shown, the shaft core 111 protrudes from the base 100 body, the stopper 130 is connected to the top of the shaft core 111, and an installation gap 113 is formed between the stopper 130 and the end surface of the base 100 body. The arc-shaped card slot 112 is longitudinally arranged; the insertion openings 310 on both sides of the lens 300 are U-shaped; when installing the lens 300, as shown in FIG. Figure 5 As shown, the locking mechanism 120 is opened, and the gap 114 is in an open state; the insertion openings 310 on both sides of the lens 300 are inserted into the installation gaps 113 on both sides from the front of the helmet body 200, and the shaft core 111 is inserted into the insertion opening 310. The stopper 130 and the end surface of the base body 110 are used to limit the left and right movement of the two side walls of the insertion opening 310, that is, to limit the left and right direction of the lens 300; Figure 6and Figure 7 As shown, when the insertion port 310 is inserted, the stop pin 320 on the lens 300 passes through the notch 114 and slides into the arc-shaped card slot 112, and then the locking mechanism 120 is closed, that is, the notch 114 is closed, the stop pin 320 is locked in the arc-shaped card slot 112, and the arc-shaped card slot 112 is used to limit the front and rear direction of the stop pin 320 to limit the front and rear direction of the lens 300, thereby completing the installation of the lens 300; when the lens 300 needs to be removed, it is only necessary to open the locking mechanism 120 to open the notch 114, and the lens 300 can be directly taken out as a whole, which is very convenient. When the lens 300 swings up and down around the axis 111, the stop pin 320 moves up and down along the arc-shaped card slot 112, and the vertical length of the arc-shaped card slot 112 is used to limit the up and down movement of the stop pin 320. When the lens 300 is mounted or dismounted, there is no need to use screws or other tools to assist. The lens 300 can be quickly mounted or dismounted by directly controlling the opening and closing of the locking mechanism 120 manually. The structure is simple, the operation is convenient, and the mounting and dismounting efficiency is high.

[0029] Reference Figure 3 , Figure 5 and Fig. 9 In some specific embodiments of the present invention, the locking mechanism 120 includes a lock 140, a latch 150 and a bolt 160. The lock 140 is rotatably connected to the base body 110 through the bolt 160 and is located on the side of the notch 114. The latch 150 is movably installed on the lock 140. The base body 110 is provided with a latch hole 115 that cooperates with the latch 150. The latch 150 moves on the lock 140 to get into or leave the latch hole 115. 5. The lock 140 is connected to the base body 110 through the bolt 160. The lock 140 rotates up and down with the bolt 160 as the axis to realize the opening and closing control of the gap 114. When in use, the latch 150 is pushed, and the latch 150 is inserted into the latch hole 115 of the base body 100, so that the lock 140 is fixed to complete the closing of the gap 114. The latch 150 is pushed away from the latch hole 115, and then the lock 140 is rotated downward to open the gap 114. This structure realizes the opening and closing of the locking structure.

[0030] Reference Figure 8 and Fig. 9 In a further embodiment of the present invention, the latch 150 is L-shaped, including a pin head 151 and a handle portion 152. The lock 140 is provided with a guide groove 141. The latch 150 slides along the guide groove 141 to telescopically move the pin head 151 on the lock 140. The handle portion 152 is manually toggled to control the movement of the latch 150 along the guide groove 141. The guide groove 141 is connected to the outside of the lock 140. After the head of the latch 150 passes through the guide groove 141, it is inserted into the latch hole 115 to fix the lock 140.

[0031] Reference Figure 3 , Figure 5 and Figure 7 In some embodiments of the present invention, a spring wire 170 is provided in the arc-shaped slot 112, and the spring wire 170 is wavy to form a plurality of recesses 171, and the shift pin 320 moves along the spring wire 170; when the lens 300 swings up and down around the axis 111, the shift pin 320 moves along the arc-shaped slot 112, and the spring wire 170 has a certain pressing effect on the shift pin 320. When the shift pin 320 is inserted into different recesses 171, each recess 171 can fix the shift pin 320 at the current position corresponding to each recess 171, thereby positioning the lens 300 at the current position, and the plurality of recesses 171 form different gears. Compared with the traditional structure of using spring pieces or tooth surface meshing to control the position of the lens 300, the use of the spring wire 170 makes it smoother for the lens 300 to swing and switch to different gears.

[0032] Reference Figure 1 , Fig.10 , Fig.11 and Fig.12 In some embodiments of the present invention, the helmet body 200 is provided with a jaw guard 210, a locking hook seat 220 is provided inside the jaw guard 210, and a locking hook 330 cooperating with the locking hook seat 220 is provided at the bottom of the lens 300; when the lens 300 swings downward until its bottom edge contacts the jaw guard 210, the locking hook 330 is locked into the locking hook seat 220 to prevent the lens 300 from swinging upward by itself due to excessive wind resistance during driving.

[0033] Furthermore, the lock hook seat 220 includes two layers of lock heads 221 distributed up and down; when the lock hook 330 is locked on the lock head 221 located at the upper side, a ventilation hole is left between the lower edge of the lens 300 and the jaw guard 210, and when the lock hook 330 is locked on the lock head 221 located at the lower side, the lower edge of the lens 300 and the jaw guard 210 are closed; the rider locks the lock hook 330 on different lock heads 221 as needed to autonomously adjust and use different ventilation effects.

[0034] In some specific embodiments of the present invention, the base 100 is made of metal to improve the structural strength of the base 100 .

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
