Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and more specifically, to a split-type helmet. Background Technology

[0002] Helmets are crucial equipment for head protection and are widely used in cycling, sports, and industrial fields. Their outer shells are typically made of high-strength materials such as ABS or carbon fiber, while the inner cushioning layer effectively absorbs impact and reduces head injury. Modern helmet designs balance lightweight construction with breathability, and some even feature smart functions like Bluetooth and lighting. Wearing a helmet correctly can significantly reduce the risk of head injuries and is an essential safety measure. Whether you're a motorcyclist, construction worker, or cycling enthusiast, choosing a suitable helmet that meets safety certifications is a responsible act towards life.

[0003] However, the inner lining of most existing helmets is fixedly installed inside the protective layer. The inner lining is easy to get dirty when it comes into contact with the skin. In addition, the temperature difference between winter and summer is large. The fixed connection method makes it inconvenient to remove the inner lining for cleaning or to replace it according to the outside temperature.

[0004] In addition, in the existing technology, the locking strap at the bottom of the helmet is mostly locked by a backpack buckle. When using the backpack buckle, the wearer needs to hold both ends of the backpack buckle to insert it. If there are things in your hands, it is not convenient to wear it with one hand. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a split helmet to solve the technical problems mentioned in the background art, such as the inconvenience of disassembling the inner liner of the split helmet and the inconvenience of installing the helmet with one hand.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A split-type helmet includes a protective layer, which refers to a structural layer in the helmet that provides substantial protection. An inner lining is provided on the inner side of the protective layer, a first Velcro strap is provided on the outer side of the inner lining, and a second Velcro strap is provided on the inner side of the protective layer. The first and second Velcro straps are attached together. Two protective ears are symmetrically arranged at the bottom of the protective layer. A locking strap is provided at the bottom of one protective ear, and a locking strip is provided at the end of the locking strap. A locking box is provided on the outer side of the other protective ear, and a locking groove is formed on the locking box. The locking strip can be inserted into the locking groove, and an insertion limiting structure is provided between the strip and the locking groove. An automatic pop-out structure is provided within the locking groove.

[0010] The present invention is further configured such that the insertion limiting structure includes a rack, the rack is integrally disposed on the outside of the locking strip, a limiting strip is disposed in the locking groove, the limiting strip can elastically engage between two adjacent sets of teeth of the rack, a guide edge is disposed at the bottom end of the limiting strip, and a spring is disposed between the outside of the limiting strip and the locking groove. When the helmet is fixed, the locking strip can be inserted into the locking groove. During this process, under the action of the guide edge, the teeth on the rack can move upward, but cannot move downward, thereby limiting the automatic outward movement of the locking groove. The spring is used to ensure that the limiting strip is pressed against the rack, thereby limiting the locking strip, and at the same time providing a movement range for the rack to enter.

[0011] The present invention is further configured such that limit sliders are provided at both ends of the limiting strip, and a limiting groove is formed on the inner wall of the locking groove. The limiting sliders slide within the limiting grooves. Through the cooperation of the limiting sliders and the limiting grooves, the movement of the limiting strip within the locking groove can be limited, thereby ensuring the stable limiting of the limiting strip on the rack.

[0012] The present invention is further configured such that the limiting slide groove on one side extends outward to the outside of the locking box, and the corresponding limiting slider extends to the outside of the locking groove, and a knob is provided. When the locking bar is released from its locking limiting state, the knob can be moved by hand, and the corresponding limiting slider is moved in the limiting slide groove by the knob, thereby realizing the movement of the limiting clip, so that the limiting clip disengages from the rack, releases the limitation on the locking bar, and allows the locking bar to exit the locking groove.

[0013] The present invention is further configured such that the automatic pop-out structure includes a gear, the gear meshes with a rack, and the gear is provided with a mounting shaft, the two ends of the mounting shaft being elastically rotatably connected to the inner wall of the locking groove.

[0014] The present invention is further configured such that a connecting groove is provided on the locking groove, the mounting shaft is connected to the connecting groove by a bearing, and a torsion spring is provided between the mounting shaft and the connecting groove. When the locking bar carries the rack into the locking groove, the meshing action between the teeth on the gear and the teeth on the rack will cause the gear to automatically rotate. During this process, the torsion spring will twist. After the limiting strip on the rack is released, the torsion spring will lose its limiting force. Under the action of the torsion spring, the gear can automatically rotate. During the rotation of the gear, the rack will be driven to move outward automatically, thereby causing the locking bar to automatically disengage from the locking groove.

[0015] The present invention is further configured such that a chin rest is movably fitted onto the locking strap to improve wearing comfort.

[0016] The present invention is further provided that a D-ring buckle is provided between the locking band and the locking strip, and the tightness of the locking band can be adjusted by the D-ring buckle, thus facilitating the adjustment of the tightness of the locking strip.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a split-type helmet, which has the following advantages:

[0019] 1. This utility model sets up a protective layer and an inner lining layer, and the protective layer and the inner lining layer are bonded together by the cooperation of the first hook and loop fastener and the second hook and loop fastener. This makes it easy to remove the inner lining layer from the protective layer for cleaning and replacement. In this way, different inner linings can be replaced according to different external temperatures, improving the flexibility of use and reducing the cold in winter and the stuffiness in summer.

[0020] 2. In this utility model, by setting a locking strap and a locking strip, and with the locking strip being equipped with a locking box, the locking strip can be held directly with one hand during use, and the locking strip is engaged into the locking groove in the locking box. During this process, the limiting strip will cooperate with the rack on the locking strip to restrict the locking strip from moving outward, thereby achieving quick locking of the locking strip on the locking box, thus enabling the helmet to be put on quickly with one hand.

[0021] 3. In this utility model, a spring, a limiting slider, a limiting groove, and a toggle button are provided in conjunction with the limiting clip. At the same time, a gear, a mounting shaft, a connecting groove, and a torsion spring are provided in conjunction with the rack. In this way, during disassembly, the toggle button can be directly moved to disengage the limiting clip from the rack, releasing the rack's limitation. Simultaneously, under the action of the torsion spring, the gear can automatically rotate, thereby driving the locking strip to automatically pop outward, realizing the quick disassembly of the helmet.

[0033] Please see Figures 1-7 A split-type helmet includes a protective layer 1, which is a structural layer in the helmet that provides substantial protection. An inner lining layer 2 is provided on the inner side of the protective layer 1, and a first Velcro 3 is provided on the outer side of the inner lining layer 2. A second Velcro 4 is provided on the inner side of the protective layer 1. The first Velcro 3 and the second Velcro 4 are attached together. Two protective ears 5 are symmetrically arranged at the bottom of the protective layer 1. A locking strap 6 is provided at the bottom of one protective ear 5, and a locking strip 7 is provided at the end of the locking strap 6. A locking box 8 is provided on the outer side of the other protective ear 5. A locking groove 9 is provided on the locking box 8. The locking strip 7 can be inserted into the locking groove 9, and an insertion limiting structure is provided between the locking strip 7 and the locking groove 9. An automatic pop-out structure is provided in the locking groove 9.

[0034] Please see Figures 1-7As one implementation of the insertion limiting structure: the insertion limiting structure includes a rack 10, which is integrally disposed on the outside of the locking strip 7. A limiting strip 11 is disposed in the locking groove 9. The limiting strip 11 can be elastically engaged between two adjacent sets of teeth of the rack 10. A guide edge 12 is provided at the bottom end of the limiting strip 11. A spring 13 is provided between the outer side of the limiting strip 11 and the locking groove 9. When the helmet is fixed, the locking strip 7 can be inserted into the locking groove 9. During this process, under the action of the guide edge 12, the teeth on the rack 10 can move upward, but cannot move downward, thereby restricting the locking groove 9 from moving outward automatically. The spring 13 is used to ensure that the limiting strip 11 is pressed against the rack 10, thereby limiting the locking strip 7, and at the same time providing a movement range for the rack 10 to enter.

[0035] Please see Figures 1-7 As one implementation of the limiting strip 11: limiting sliders 14 are provided at both ends of the limiting strip 11, and limiting grooves 15 are provided on the inner wall of the locking groove 9. The limiting sliders 14 slide within the limiting grooves 15. Through the cooperation of the limiting sliders 14 and the limiting grooves 15, the movement of the limiting strip 11 within the locking groove 9 can be limited, thereby ensuring the stable limiting of the limiting strip 11 on the rack 10.

[0036] Furthermore, one side of the limiting slide groove 15 extends outward to the outside of the locking box 8, and the corresponding limiting slider 14 extends to the outside of the locking groove 9, and is provided with a knob 16. When the locking bar 7 is released from its locking limiting state, the knob 16 can be moved by hand. The knob 16 drives the corresponding limiting slider 14 to move within the limiting slide groove 15, thereby realizing the movement of the limiting clip 11, so that the limiting clip 11 disengages from the rack 10, releases the limiting of the locking bar 7, and allows the locking bar 7 to exit the locking groove 9.

[0037] Please see Figures 1-7 As one implementation of the automatic pop-out structure: the automatic pop-out structure includes a gear 17, which meshes with a rack 10. A mounting shaft 18 is provided on the gear 17, and both ends of the mounting shaft 18 are elastically rotatably connected to the inner wall of the locking groove 9.

[0038] Please see Figures 1-7As one embodiment of the locking groove 9: a connecting groove 19 is provided on the locking groove 9, and the mounting shaft 18 is connected to the connecting groove 19 by a bearing. A torsion spring 20 is provided between the mounting shaft 18 and the connecting groove 19. When the locking bar 7 carries the rack 10 into the locking groove 9, the meshing action between the teeth on the gear 17 and the teeth on the rack 10 will cause the gear 17 to carry the mounting shaft 18 to rotate automatically. During this process, the torsion spring 20 will twist. After the limiting strip 11 releases the limiting force on the rack 10, the torsion spring 20 will lose its limiting force. Under the action of the torsion spring 20, the gear 17 can rotate automatically. During the rotation of the gear 17, the rack 10 will be driven to move automatically outward, thereby causing the locking bar 7 to automatically disengage from the locking groove 9.

[0039] Please see Figures 1-7 As one embodiment of the locking strap 6: a chin rest 21 is movably fitted on the locking strap 6 to improve wearing comfort.

[0040] Please see Figures 1-7 As one implementation of the locking band 6: a D-ring buckle 22 is provided between the locking band 6 and the locking strip 7, and the locking band 6 can be adjusted in tightness through the D-ring buckle 22, thus facilitating the adjustment of the tightness of the locking strip 7.
