Description

Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to a helmet with a magnetic quick-release goggle structure. Background Technology

[0002] As a key component of a helmet, goggles offer multiple functions, including protection against wind and sand, flying insects, UV rays, and impacts. They provide effective protection for the user's eyes, ensuring clear vision in various complex environments. However, in different usage scenarios, users may need to quickly change goggles according to different lighting conditions, weather conditions, or personal needs to meet diverse requirements. Therefore, goggles need to be detachable.

[0003] For example, the utility model patent with publication number CN205512590U discloses a quick-change helmet lens structure. This patent discloses a quick-change helmet lens structure, including a visual frame connected to the helmet shell, a lens holder for fixing the lens, and a lens. The lens holder frame has multiple positioning slots distributed in the frame for assembling a first magnet. The visual frame has assembly slots for assembling a second magnet corresponding to each positioning slot. The second magnet is engaged in the assembly slot, and the front end of the second magnet is attracted to the first magnet.

[0004] The aforementioned structure enables quick lens replacement via magnetic attraction, but there are certain issues with the installation and fixation of the magnets. The design of its positioning and assembly slots may not be stable enough. During long-term use, the magnets are prone to displacement due to vibration or external forces, affecting the magnetic attraction and causing the goggles to wobble or fall off. For example, during cycling, the helmet is subjected to vibrations from various directions. If the magnets are not securely fixed, the goggles may loosen, affecting the user's vision and safety. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a helmet with a magnetic quick-release goggle structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A helmet with a magnetic quick-release goggle structure includes a helmet body, a goggle, and a quick-release structure. Connecting plates are provided on both sides of the goggle, and the quick-release structure is mounted on these connecting plates. The goggle is rotatably connected to the helmet body via the quick-release structures on both sides. The quick-release structure includes a rotating bracket rotatably mounted on the helmet body, a buckle movably mounted on the connecting plates, a guide drive mechanism mounted on the connecting plates, and magnets mounted on the connecting plates and the rotating bracket respectively. One end of the buckle engages with the guide drive mechanism, and the other end engages with the rotating bracket. The guide drive mechanism includes a guide plate, a drive plate, and a knob. The guide plate is fixedly connected to the connecting plate via a connector, and the guide plate and the connecting plate are spaced apart. The drive plate rotatably engages between the guide plate and the connecting plate. The knob is connected to the drive plate and can drive the drive plate to rotate. The drive plate has a drive structure for moving the buckle, and both the guide plate and the connecting plate have guide structures for guiding the buckle.

[0008] Furthermore, the driving structure is a long, curved hole that spirals from the side of the driving disk near the outer edge toward the center of the disk, and the guiding structure is a long, straight hole that radially extends from the side of the outer edge of the guide disk and the connecting disk toward the center.

[0009] Furthermore, the buckle has a columnar structure, including a guide portion, a drive portion, and a snap-fit ​​portion. The guide portion is provided in two sets, with the two sets of guide portions located on both sides of the drive portion. The snap-fit ​​portion is connected to one of the guide portions. The two sets of guide portions are respectively engaged in the guide structure on the guide plate and the connecting plate. The drive portion is engaged in the drive structure on the drive plate between the guide plate and the connecting plate. The snap-fit ​​portion is located on the side closer to the connecting plate.

[0010] Furthermore, the rotating card holder is provided with a slot / hole corresponding to the position of the locking part. The slot / hole includes a movable part and a locking part. When the connecting plate is attracted and attached to the rotating card holder by the magnet, the locking part extends into the movable part. When the driving structure drives the buckle to move towards the center, the locking part is locked into the locking part.

[0011] Furthermore, the connector is provided with a positioning structure for limiting the angle, and the center of the rotating bracket is provided with a positioning groove that cooperates with the positioning structure. When the connecting plate is in contact with the rotating bracket, it is positioned by inserting the positioning structure into the positioning groove, and the position of the snap-fit ​​part corresponds exactly to the position of the movable part.

[0012] Furthermore, the edges of the positioning structure are rounded.

[0013] In this invention, the outer wall of the knob is provided with anti-slip stripes.

[0014] In this utility model, the knob is provided with an assembly hole near the edge, and a slidable locking block is installed in the assembly hole. The connecting plate is provided with a locking groove. When the knob is rotated until the buckle is engaged with the rotating base, the locking block and the locking groove are aligned. The locking block is pushed outward to engage with the locking groove, thereby fixing the knob.

[0015] This utility model has the following advantages and beneficial effects:

[0016] By incorporating quick-release mechanisms on the connecting plates on both sides of the goggles, this structure includes a rotating bracket, a buckle, a guide drive mechanism, and magnets mounted on the connecting plate and the rotating bracket respectively. When installing the goggles, the magnets first attract the connecting plate to the rotating bracket, and then the rotating guide drive mechanism drives the buckle to engage with the rotating bracket for locking. This dual-fixation method effectively avoids the problem of magnet displacement due to vibration or external force when relying solely on magnetic attraction, greatly enhancing the stability of the connection between the goggles and the helmet. This ensures that the goggles will not shake or fall off in various complex usage scenarios, such as when experiencing vibrations from various directions during riding, providing the user with a clear and stable field of vision and guaranteeing safety.

[0029] like Figures 1 to 8 As shown, this embodiment discloses a helmet with a magnetic quick-release goggle structure, including a helmet body 1, a goggle 2, and a quick-release structure 3. Connecting plates 21 are provided on both sides of the goggle 2. The quick-release structure 3 is disposed on the connecting plates 21 on both sides of the goggle 2. The goggle 2 is rotatably connected to the helmet body 1 via the quick-release structures 3 on both sides. The quick-release structure 3 includes a rotating bracket 31 rotatably mounted on the helmet body 1, a buckle 32 movably mounted on the connecting plates 21, a guide drive mechanism 33 mounted on the connecting plates 21, and magnets 3 respectively mounted on the connecting plates 21 and the rotating bracket 31. 4. One end of the buckle 32 is connected to the guide drive mechanism 33, and the other end is engaged with the rotating bracket 31. When installing the goggles 2, the connecting plate 21 is first connected to the rotating bracket 31 by the attraction of the magnet 34. Then, the buckle 32 is engaged into the rotating bracket 31 by rotating the guide drive mechanism 33 to limit the position. This can prevent the magnet 34 from shifting due to vibration or external force, which would cause the goggles 2 to shake or fall off. When disassembling, the buckle 32 can be disengaged by the guide drive mechanism 33 to overcome the magnetic attraction and remove the goggles 2, thus achieving the purpose of quick disassembly and assembly.

[0030] In this embodiment, the guide drive mechanism 33 includes a guide disk 331, a drive disk 332, and a knob 333. The guide disk 331 is fixedly connected to the connecting disk 21 via a connector 334. The guide disk 331 and the connecting disk 21 are spaced apart to form a rotating cavity. The drive disk 332 is rotatably fitted within the rotating cavity. The knob 333 is connected to the drive disk 332, and the knob 333 can drive the drive disk 332 to rotate within the rotating cavity. It should be noted that the inner diameter of the knob 333 is larger than that of the guide disk 331. The outer diameter of the knob 333 is such that the knob 333 covers the guide disk 331 and is fixedly connected to the drive disk 332. That is, the guide disk 331 is located inside the knob 333. The connector 334 passes through the connecting disk 21 and the drive disk 332 from one side of the connecting disk 21 and connects to the guide disk 331 inside. This allows the guide disk 331 and the connecting disk 21 to be fixed, while the drive disk 332 and the knob 333 can rotate relative to each other. Preferably, the outer wall of the knob 333 is provided with anti-slip stripes 3331 to facilitate rotation.

[0031] Furthermore, the drive disk 332 is provided with a drive structure 3321 for driving the latch 32 to move. The guide disk 331 and the connecting disk 21 are both provided with guide structures 3311 for guiding the latch 32. The drive structure 3321 is a long, curved hole that spirals from the side of the drive disk 332 near the outer edge toward the center of the disk. The guide structure 3311 is a long, straight hole that radially extends from the side of the outer edge of the guide disk 331 and the connecting disk 21 toward the center. When the knob 333 drives the drive disk 332 to rotate, the drive disk 332 drives the latch 32 to move along the guide structure 3311 through the drive structure 3321.

[0032] Furthermore, the buckle 32 has a columnar structure, specifically including a guide portion 321, a driving portion 322, and a locking portion 323. The guide portion 321 has two sets, located on both sides of the driving portion 322. The locking portion 323 is connected to one of the guide portions 321. The two sets of guide portions 321 respectively cooperate with the guide structures 3311 on the guide plate 331 and the connecting plate 21. The driving portion 322 cooperates with the driving structure 3321 on the driving plate 332. The locking portion 323 is located on the side closer to the connecting plate 21. For ease of installation, The width of the guide structure 3311 on the connecting plate 21 is greater than the diameter of the snap-fit ​​part 323. In addition, the rotating card holder 31 is provided with a slot / hole 310 corresponding to the position of the snap-fit ​​part 323. The slot / hole 310 includes a movable part 3101 and a locking part 3102. When the connecting plate 21 is attracted and attached to the rotating card holder 31 by the magnet 34, the snap-fit ​​part 323 extends into the movable part 3101. When the driving structure 3321 drives the buckle 32 to move towards the center, the snap-fit ​​part 323 snaps into the locking part 3102, thereby forming a snap-fit ​​limit.

[0033] Furthermore, in order to enable the snap-fit ​​part 323 to quickly enter the movable part 3101, a positioning structure 3341 for limiting the angle is provided on the connector 334, and a positioning groove 3342 that cooperates with the positioning structure 3341 is also provided in the middle of the rotating base 31. When the connecting plate 21 is attached to the rotating base 31, it is positioned by inserting the positioning structure 3341 into the positioning groove 3342, and the position of the snap-fit ​​part 323 corresponds exactly to the position of the movable part 3101, thereby enabling quick assembly. In addition, the edges of the positioning structure 3341 are rounded to facilitate insertion.

[0034] In this embodiment, to prevent the knob 333 from rotating arbitrarily, a mounting hole 3330 is provided near the edge of the knob 333. A sliding locking block 3332 is mounted in the mounting hole 3330. In addition, a locking groove 211 is provided on the connecting plate 21. When the knob 333 is rotated until the buckle 32 is engaged with the rotating base 31, the locking block 3332 corresponds to the locking groove 211. At this time, pushing the locking block 3332 outward will cause it to engage in the locking groove 211, thus fixing the knob 333 and preventing it from rotating.

[0035] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
