Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a flexible-wearable emergency helmet lighting device. Background Technology

[0002] A helmet light is a lighting device mounted on a helmet for illumination, providing a good lighting environment and widely used in emergency rescue and disaster relief. Existing helmet lights typically use a base fixed to the helmet, with the light body rotatably connected to the base via a hinge. During emergency rescue operations, the hinge allows the light body to rotate relative to the base, adjusting the lighting angle. However, emergency rescue environments are complex, and the light body's fixation relies on the helmet. In environments with many obstacles, the light is prone to impacts that can cause the hinge to break, leading to the light body detaching from the base. Furthermore, the lighting direction changes as rescuers turn their heads, making it difficult to maintain continuous illumination in the same direction and impacting rescue efficiency. Therefore, designing a flexible, adaptable emergency helmet light that allows for adjustments to the wearing method and control of the lighting direction based on the environment has become an urgent technical challenge. Summary of the Invention

[0003] To solve the above problems, this utility model provides a flexible-wearable emergency helmet light.

[0004] The present invention provides a flexible-wearable emergency helmet light, comprising a light body and a mounting plate connected to the helmet. The light body has an independent power supply installed inside and a back cover on the back. The bottom of the back cover has an upwardly extending slot, and magnets are connected to both sides of the back. The top of the slot has a slot that connects to the back of the back cover. The bottom of the mounting plate has a connecting ear and a mounting hole in the middle or a hanging ear hole on the edge. The connecting ear is connected to a horizontal rotating shaft, and an insert plate is connected to the rotating shaft. The insert plate is inserted into the slot, and the top of the insert plate has a locking block with an arc surface protruding into the locking slot.

[0005] With the above structure, the mounting plate has mounting holes, allowing screws to be passed through these holes to connect the mounting plate to the helmet. The connecting lugs at the bottom of the mounting plate are pivotally connected to the insert plate. The insert plate, inserted upwards, is inserted into the slot and connects to the rear cover of the lighting unit. The arc-shaped protrusion of the locking block into the slot prevents the insert plate from sliding downwards out of the slot, pushing the lighting unit and insert plate to rotate around the pivot, adjusting the lighting angle of the lighting unit on the helmet. By pulling the insert plate downwards from the slot, the edge of the slot and the inner wall of the slot press against the arc-shaped surface of the locking block, causing the block to deform and be pressed into the slot until it passes through the slot opening. The locking block then returns to its original position, completing the separation of the lighting unit from the mounting plate. Power is supplied by an independent power source installed inside the lighting unit, facilitating flexible handheld illumination. When there are many obstacles in the environment, magnets can be connected to both sides of the back of the rear cover. The system uses magnets to attach to steel bars or other metal objects at the disaster relief site, providing stable directional lighting. Instead of fixing the mounting plate to the helmet, a lanyard or clothing strap is threaded through the ear holes on the mounting plate, allowing the plate and the main body of the light to be carried on the rescuer's body. This facilitates quick removal and replacement of the helmet-mounted light if it is damaged, or passing the light to others. The mounting plate connects to the helmet via mounting holes, and the light body connects to the mounting plate via a slot on the back cover. Even after being removed, the light body can still attract metal objects at the scene using magnets on the back of the back cover, creating a stable light source. The lanyard, threaded through the ear holes, allows the light to be carried as a backup light, making the wearing and securing of the light more flexible and ensuring rescue efficiency.

[0006] As a further improvement of this utility model, the middle part of the rotating shaft is provided with a gear coaxial with itself, the connecting ear is provided with a positioning plate, the positioning plate is provided with a positioning protrusion, and the positioning protrusion is engaged in any tooth groove of the gear.

[0007] With the above structure, a coaxial gear is set in the middle of the rotating shaft, and a positioning plate is provided on the connecting ear. A positioning protrusion is set on the positioning plate and is locked in any tooth groove of the gear to prevent the rotating shaft from rotating without external force. When the lighting body and the insert plate are pushed to rotate around the rotating shaft, the positioning protrusion is deformed by the pressure between the gear teeth and the positioning protrusion. The positioning protrusion passes over the gear teeth, enters the next tooth groove, and returns to its original shape until the rotation of the lighting body is stopped.

[0008] As a further improvement of this utility model, a limiting baffle is provided at the lower end of the rotating shaft. When the insert plate rotates around the rotating shaft to a state perpendicular to the mounting plate, the limiting baffle abuts against the end of the positioning plate away from the mounting plate.

[0009] With the above structure, a limiting baffle is provided at the lower end of the rotating shaft. When the insert plate rotates around the rotating shaft to a state perpendicular to the mounting plate, the limiting baffle abuts against the end of the positioning plate away from the mounting plate, preventing the insert plate from continuing to rotate. This limits the maximum rotation angle between the lighting body and the insert plate, preventing the lighting body from facing the helmet due to excessive rotation angle.

[0010] As a further improvement of this utility model, the slot opening is provided with a guide opening extending to the back of the rear cover. The guide opening is spaced below the card slot. The back of the insert plate is provided with a protruding guide plate. The position and size of the guide plate correspond to the guide opening.

[0011] With the above structure, the slot has a guide opening extending to the back of the rear cover, and the back of the insert plate has a guide plate. The position and size of the guide plate correspond to the guide opening. When the insert plate is inserted into the slot, the guide plate will also be inserted into the guide opening from the slot and press against the upper edge of the guide opening, supporting the main body of the lamp together with the insert plate. The raised guide plate increases the thickness of the insert plate, making the insert plate less prone to breakage. The guide opening is spaced below the card slot, so that when the card block moves between the slot and the slot, it will not be squeezed at the guide opening, reducing the wear of the card block.

[0012] As a further improvement of this utility model, the top edges of the insert plate and the guide plate are provided with rounded corners formed by chamfering.

[0013] With the above structure, the top edges of the insert plate and guide plate are chamfered to form rounded corners, which correspond to the edges of the contact slot and guide opening. The insert plate and guide plate slide into the slot and guide opening, reducing the difficulty of inserting and removing the main body of the helmet lighting in an emergency.

[0014] As a further improvement of this utility model, the back of the guide plate is provided with a recessed indicator mark, the shape of which includes an arrow pointing to the card block.

[0015] With the above structure, by setting a recessed indicator on the back of the guide plate, the shape of the indicator includes an arrow pointing to the card block, prompting the person who gets the light to pay attention to the position of the card block. After inserting the insert plate into the slot, it is also necessary to pay attention to whether the arc surface of the card block enters the slot, so that the insert plate is fixed in the slot.

[0016] As a further improvement of this utility model, the mounting hole is a rectangular hole or a semi-circular hole, and the ear hole is a strip-shaped hole with an opening that connects to the side of the mounting plate.

[0017] With the above structure, the mounting holes are rectangular or semi-circular, which can accommodate screws of different sizes and different fixing positions when multiple screws pass through a mounting hole. The ear holes are strip-shaped and have openings that connect to the side of the mounting plate. When both ends of the strap are connected to the clothing, the middle part of the strap can be twisted to form a ring. One side of the ring is passed through the opening into the ear hole, fits the edge of the mounting plate, and moves to the end of the ear hole, connecting the mounting plate to the strap of the clothing.

Detailed Implementation

[0021] like Figures 1-2 The present invention discloses a flexible wearable emergency helmet light, comprising a light body 1 and a mounting plate 2 connected to the helmet. The light body 1 has an independent power supply installed inside and a back cover 3 on the back. The bottom of the back cover 3 has an upwardly extending slot 4, and magnets 5 are connected to both sides of the back. The top of the slot 4 has a slot 6 that connects to the back of the back cover 3. The bottom of the mounting plate 2 has a connecting ear 7, and also has a mounting hole 8 in the middle or a hanging ear hole 9 on the edge. The connecting ear 7 is axially connected to a horizontal rotating shaft 10, and an insert plate 11 is connected to the rotating shaft 10. The insert plate 11 is inserted into the slot 4, and the top of the insert plate 11 has a locking block 12, which has an arc surface protruding into the locking slot 6.

[0022] Mounting plate 2 has mounting holes 8, allowing screws to be passed through them to connect it to the helmet. The connecting lugs 7 at the bottom of mounting plate 2 are pivotally connected to insert plate 11. Insert plate 11 is inserted upwards into slot 4 and connected to the rear cover 3 of the lighting body 1. The arc-shaped surface of the locking block 12 protrudes into the slot 6, preventing the insert plate 11 from falling out of the slot 4. This pushes the lighting body 1 and insert plate 11 to rotate around the pivot 10, adjusting the lighting angle of the lighting body 1 on the helmet. By pulling the insert plate 11 downwards from the slot 4, the edge of the slot 6 and the inner wall of the slot 4 press against the arc-shaped surface of the locking block 12, causing the locking block 12 to deform and be pressed into the slot 4 until it passes through the opening of the slot 4. The locking block 12 then returns to its original position, completing the separation of the lighting body 1 from the mounting plate 2. Power is supplied by an independent power source installed inside the lighting body 1, facilitating flexible handheld illumination. When there are many obstacles in the environment, the back of the rear cover 3 can also be used for illumination. Magnets 5 are connected to both sides, which can be used to attach the magnets 5 to steel bars or other metal objects at the disaster relief site, providing stable directional lighting. Instead of fixing the mounting plate 2 to the helmet, a lanyard or a strap from clothing can be threaded through the ear holes 9 on the mounting plate 2 to hang the mounting plate 2 and the main body of the lighting lamp 1 on the body of the rescuer. If the main body of the lighting lamp 1 on the helmet is damaged, it is easy to quickly remove the main body of the lighting lamp 1 from the body for replacement, or to pass the lighting lamp to others. The mounting holes 8 on the mounting plate 2 are connected to the helmet, and the main body of the lighting lamp 1 is connected to the insert plate 11 connected to the mounting plate 2 through the slot 4 of the back cover 3. After being removed, the main body of the lighting lamp 1 can still be attached to metal objects at the scene by the magnets 5 on the back of the back cover 3, forming a stable light source. The lighting lamp can be hung on the body of the rescuer by threading a lanyard through the ear holes 9, serving as a spare lighting lamp for easy carrying. The wearing and fixing methods of the lighting lamp are more flexible, ensuring the efficiency of disaster relief.

[0023] The rotating shaft 10 has a gear 13 coaxial with itself in the middle, the connecting ear 7 has a positioning plate 14, the positioning plate 14 has a positioning protrusion 15, and the positioning protrusion 15 is engaged in any tooth groove of the gear 13.

[0024] By setting a coaxial gear 13 in the middle of the rotating shaft 10, and a positioning plate 14 on the connecting ear 7, a positioning protrusion 15 is set on the positioning plate 14. The positioning protrusion 15 is locked in any tooth groove of the gear 13, preventing the rotating shaft 10 from rotating without external force. When the lighting body 1 and the insert plate 11 are pushed to rotate around the rotating shaft 10, the positioning protrusion 15 is deformed by the pressure of the gear teeth of the gear 13. The positioning protrusion 15 passes over the gear teeth of the gear 13 and enters the next tooth groove and returns to its original shape until the rotation of the lighting body 1 stops.

[0025] The lower end of the rotating shaft 10 is provided with a limiting baffle 16. When the insert plate 11 rotates around the rotating shaft 10 to a state perpendicular to the mounting plate 2, the limiting baffle 16 abuts against the end of the positioning plate 14 away from the mounting plate 2.

[0026] A limiting baffle 16 is provided at the lower end of the rotating shaft 10. When the insert plate 11 rotates around the rotating shaft 10 to a state perpendicular to the mounting plate 2, the limiting baffle 16 abuts against the end of the positioning plate 14 away from the mounting plate 2, preventing the insert plate 11 from continuing to rotate. This limits the maximum rotation angle between the lighting body 1 and the insert plate 11, preventing the front of the lighting body 1 from facing the helmet due to excessive rotation angle.

[0027] The slot 4 has a guide opening 17 extending to the back of the rear cover 3. The guide opening 17 is spaced below the card slot 6. The back of the insert plate 11 has a protruding guide plate 18. The position and size of the guide plate 18 correspond to the guide opening 17.

[0028] The slot 4 has a guide opening 17 extending to the back of the rear cover 3. The back of the insert plate 11 has a guide plate 18. The position and size of the guide plate 18 correspond to the guide opening 17. When the insert plate 11 is inserted into the slot 4, the guide plate 18 will also be inserted into the guide opening 17 from the slot 4 and press against the upper edge of the guide opening 17. Together with the insert plate 11, it supports the lighting body 1. The protruding guide plate 18 increases the thickness of the insert plate 11, making the insert plate 11 less prone to breakage. The guide openings 17 are spaced below the card slot 6 so that when the card block 12 moves between the card slot 6 and the slot 4, it will not be squeezed at the position of the guide opening 17, reducing the wear of the card block 12.

[0029] The top edges of the insert plate 11 and the guide plate 18 are chamfered to form rounded corners.

[0030] The top edges of the insert plate 11 and the guide plate 18 are chamfered to form rounded corners, which correspond to the edges of the contact slot 4 and the guide opening 17. The insert plate 11 and the guide plate 18 slide into the slot 4 and the guide opening 17, reducing the difficulty of inserting and removing the main body 1 of the helmet lighting lamp in an emergency.

[0031] The back of the guide plate 18 is provided with a recessed indicator mark 19, the shape of which includes an arrow pointing to the card block 12.

[0032] By setting a recessed indicator 19 on the back of the guide plate 18, the shape of the indicator 19 includes an arrow pointing to the card block 12, prompting the person who gets the light to pay attention to the position of the card block 12. After inserting the insert plate 11 into the slot 4, it is also necessary to pay attention to whether the arc surface of the card block 12 enters the slot 6, so that the insert plate 11 is fixed in the slot 4.

[0033] The mounting hole 8 is a rectangular hole or a semi-circular hole, and the ear hole 9 is a strip-shaped hole with an opening that connects to the side of the mounting plate 2.

[0034] The mounting hole 8 is a rectangular or semi-circular hole, which can accommodate screws of different sizes and different fixing positions when multiple screws pass through a mounting hole 8; the ear hole 9 is a strip-shaped hole with an opening that connects to the side of the mounting plate 2. When both ends of the strap are connected to the clothing, the middle part of the strap can be twisted to form a ring. One side of the ring is passed through the opening into the ear hole 9, fits the edge of the mounting plate 2, and moves to the end of the ear hole 9 to connect the mounting plate 2 to the strap of the clothing.
