Description

Technical Field

[0001] This invention relates to the field of safety helmet technology, specifically to a pair of goggles and an off-road safety helmet. Background Technology

[0002] Existing off-road safety helmets typically do not come with goggles. If off-road riders need to protect their eyes, they usually need to buy standard-sized goggles themselves. These goggles are usually worn close to the face, which can cause a tight and pressured feeling on the face. Moreover, in order to make them easy to wear, they need to be large enough to fit through the helmet window, so they are relatively small in size, which can also affect the field of vision when wearing them. The wearing process is also relatively inconvenient, resulting in a poor user experience. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this invention is to provide a pair of goggles and an off-road safety helmet that are convenient and comfortable to wear and have a wide field of vision.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A type of goggle includes a frame and a lens, the lens being mounted on the frame, and the frame having a bent edge along its upper and lower edges for engaging with the window edge of a helmet body.

[0005] It also includes an elastic band, one end of which is connected to one side of the frame or lens, and the other end of which is connected to the other side of the frame or lens.

[0006] Both sides of the frame or lens are rotatably connected to an adjusting member. The part of the adjusting member located on the outside of the frame or lens is a handle, and the part of the adjusting member located on the inside of the frame or lens is an adjusting block. The handle and the adjusting block rotate synchronously. The adjusting block has a contact surface, and the contact surface is eccentrically positioned relative to the rotation center axis of the adjusting member.

[0007] The adjusting component also includes a locking screw; one end of the handle is suspended, and the other end of the handle is provided with a rotating shaft; the two sides of the frame or lens are provided with through holes that rotatably engage with the rotating shaft; the adjusting block is provided with a socket that engages with the rotating shaft; the socket is provided with an anti-rotation protrusion extending along the depth direction of the socket, and the rotating shaft is provided with an anti-rotation groove that is adapted to and engages with the anti-rotation protrusion; the locking screw passes through the adjusting block and is threadedly connected to the rotating shaft; the handle and the adjusting block clamp the frame or lens.

[0008] Both sides of the frame or lens are provided with side covers, which cooperate with the frame or lens to form a cavity with an opening facing backward. The part of the handle that connects to the adjustment block is placed in the cavity, and the other part of the handle extends out of the cavity.

[0009] The nose pad is detachably installed at the middle of the lower edge of the frame.

[0010] The present invention also discloses an off-road safety helmet, which includes a helmet body and the aforementioned goggles. The helmet body has a window, and the shape of the goggle frame is adapted to the shape of the window. The goggle frame and the lens cooperate to cover the window.

[0011] The eyeglass frame is fitted onto the helmet body with an elastic band; the edge of the window is provided with a sealing strip to seal the gap between the window and the eyeglass frame.

[0012] When the adjusting component is rotated, the abutting surface can press against the edge of the window; when the abutting surface presses against the edge of the window, a ventilation channel connecting the helmet body to the outside is formed between the frame and the edge of the window.

[0013] The helmet body has breathing holes corresponding to the human mouth and nose position.

[0014] By adopting the above solution, and ensuring that the bent edge of the goggles matches the stop edge of the helmet's window, the goggles do not need to be worn tightly against the face, which improves wearing comfort. At the same time, the wearer's field of vision is almost unaffected by the frame, providing a wider field of vision. Furthermore, because the goggles are located on the outside of the helmet, it is very convenient for the user to put on or remove the helmet or goggles. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1-14 As shown, this invention discloses an off-road safety helmet, which includes a helmet body 10 and a visor 20. The helmet body 10 has a window 11 and a wearing opening, through which the user's head enters the inner cavity of the helmet body 10. The window 11 provides the wearer with a field of vision. A breathing hole 12, which communicates with the outside atmosphere, is provided on the helmet body 10 at the position corresponding to the human mouth and nose.

[0020] The goggles 20 include a frame 21, a lens 22, and an elastic band 23. The lens 22 is mounted on the frame 21. The shape of the frame 21 is adapted to the shape of the window 11. The frame 21 and the lens 22 cooperate to cover the window 11. To prevent the goggles 21 from extending too far into the window 11 and pressing on the face, and to ensure the distance between the goggles 20 and the face, as well as to ensure the installation stability of the goggles 20, a bent edge 24 is integrally formed on the upper and lower edges of the frame 21. The bent edge 24 is engaged with the edge of the window 11 of the helmet body 10. That is, a recess is formed between the upper and lower edges of the frame 21 and the bent edge 24. The edge of the window 11 of the helmet body 10 is stuck in the recess, thereby realizing the stop and positioning of the frame 21.

[0021] One end of the elastic band 23 is connected to one side (e.g., the left side) of the lens frame 21 (preferably a detachable connection, such as a buckle connection), and the other end of the elastic band 23 is connected to the other side (e.g., the right side) of the lens frame 21 (preferably a detachable connection, such as a buckle connection). Alternatively, one end of the elastic band 23 is connected to one side of the lens 22, and the other end of the elastic band 23 is connected to the other side of the lens 22. The lens frame 21 and the elastic band 23 can cooperate to form a loop, thereby securing it to the helmet body 10. Under the elastic force of the elastic band 23, the lens frame 21 can be firmly pressed against the window 11.

[0022] In addition, to prevent dust or rainwater from entering the helmet body 10 through the gap between the window 11 and the frame 21, a sealing strip can be provided on the edge of the window 11 to seal the gap. The sealing strip can also play a buffering role.

[0023] To achieve controllable helmet ventilation, adjusting members 30 are rotatably connected to both sides of the visor frame 21 or lens 22. By rotating the adjusting members 30, the visor frame 21 is moved a certain distance away from the edge of the window 11, thereby creating a ventilation channel and enabling the exchange of air between the inside and outside of the helmet. Specifically, the part of the adjusting member 30 located on the outside of the visor frame 21 or lens 22 is a handle, and the part of the adjusting member 30 located on the inside of the visor frame 21 or lens 22 is an adjusting block 32 (in this embodiment, the adjusting block 32 is implemented using a cam). Before the adjusting member 30 is assembled, the handle and the adjusting block 32 are two independent components. This arrangement facilitates assembly with the adjusting member 30 or lens 22.

[0024] The handle and adjusting block 32 are connected as follows: one end of the handle is suspended for easy operation, while the other end has a rotating shaft 33. Through holes 25, which rotatably engage with the rotating shaft 33, are provided on both sides of the frame 21 or lens 22. The diameter of these through holes 25 matches the diameter of the rotating shaft 33. The adjusting block 32 has insertion holes 34 that engage with the rotating shaft 33. An anti-rotation protrusion 35 extending along the depth direction is also provided in the insertion hole 34. The rotating shaft 33 has an anti-rotation groove 37 that matches and engages with the anti-rotation protrusion 35. The engagement of the anti-rotation protrusion 35 and the anti-rotation groove 37 allows the handle and adjusting block 32 to rotate synchronously. Furthermore, to ensure a stable connection between the handle and adjusting block 32, a locking screw passes through the adjusting block 32 and is threaded onto the rotating shaft 33 for secure fastening. After the handle and adjusting block 32 are fastened together with the locking screw, the handle and adjusting block 32 clamp the frame 21 or the lens 22, thereby preventing the adjusting part 30 from falling off.

[0025] The adjusting block 32 has a contact surface 36, which is eccentrically positioned relative to the rotation axis of the adjusting member 30. This contact surface 36 is the part of the adjusting block 32 furthest from the rotation axis of the adjusting member 30. Normally, the contact surface 36 does not contact the edge of the window 11, and the adjusting block 32 does not interfere with the frame 21 pressing against the edge of the window 11. Rotating the handle causes the adjusting block 32 to rotate, allowing the contact surface 36 to press against the edge of the window 11. At this time, the adjusting block 32 pushes the frame 21 away from the window 11, forming a ventilation channel connecting the frame 21 to the outside of the helmet body 10. The elastic band 23 maintains the posture of the adjusting block 32, and the ventilation channel is maintained even after the handle is released.

[0026] Both sides of the frame 21 or lens 22 are connected to side covers 26 (which can be connected by snap-fit). The side covers 26 and the frame 21 or lens 22 cooperate to form a rearward-opening cavity. The part of the handle connected to the adjustment block 32 is placed in the cavity, while the other part of the handle extends out of the cavity for manual operation. The end of the elastic band 23 is also placed in the cavity. In this way, when looking directly at the helmet body 10, the side covers 26 can cover the handle and the end of the elastic band 23, which is aesthetically pleasing and also provides a certain degree of protection.

[0027] In addition, to improve the wearing comfort of the helmet, a nose pad 40 is detachably installed at the middle of the lower edge of the visor frame 21. The nose pad 40 is designed to be detachable for easy replacement, and the user can choose a nose pad 40 that fits their nose shape. The nose pad 40 can be connected to the lower edge of the visor frame 21 by means of plugging, snapping, or gluing, or the nose pad 40 can be held in place by the visor frame 21 and the window 11.

[0028] The key to this invention lies in the fact that by having the bent edge 24 on the goggles 20 engage with the edge of the window 11 of the helmet body 10, the goggles 20 do not need to be worn tightly against the face, which improves wearing comfort. Simultaneously, the wearer's field of vision is almost unaffected by the frame 21, providing a wider field of vision. Furthermore, because the goggles 20 are located outside the helmet body 10, it is convenient for the user to put on or take off the helmet or goggles 20. Additionally, the goggles 20, in conjunction with the elastic band 23, are fastened to the outside of the helmet body 10, allowing for quick, convenient, and reliable wearing. The adjustment component 30 creates a ventilation channel between the goggles 20 and the window 11 of the helmet body 10, facilitating heat dissipation and ventilation, and preventing the lenses 22 from fogging up due to exhaled moisture.

[0029] The above description is merely an embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
