The hinge device includes a first hinge arm and a second hinge arm, and the two hinge arms are connected by a hinge seat and a pin shaft.

The abutting surfaces of the first hinge arm and the second hinge arm are provided with bosses that engage with each other.

The tail ends of the first hinge arm and the second hinge arm are provided with hooks, and the hooks are hooked and fixed in the fixed block or the movable block.

The first hinge arm and the second hinge arm are integrated with the fixed block or the movable block by in-molding.

The movable block includes a first movable block and a second movable block, and the two movable blocks are connected by a hinge device.

The latch device includes a latch head and a latch seat, the latch head is inserted into the fixing hole of the latch seat, and the relative position between the two is fixed by a locking pin.

A locking hole is arranged on the bolt head, and the locking pin is inserted into the locking hole to be fixed after passing through the chute on the bolt seat.

The docking device is a boss and a groove arranged on the docking surface of the first fixing block and the second fixing block. After the helmet is opened, the boss is inserted into the groove for docking.

The beneficial effects of the invention are as follows: 1. Simple structure, low production cost and improved market competitiveness. 2. The helmet is divided into several parts that are independent of each other, and the parts are connected by a hinge device. When the helmet is not in use, the hinge device can be used to fold each part to reduce the volume and facilitate portability.

detailed description

The present invention will be specifically and further described below in conjunction with the accompanying drawings. A foldable helmet is characterized in that it includes a first fixed block 1, a second fixed block 2, a movable block 3 is also arranged between the two fixed blocks 2, and a gap between the first fixed block 1 and the second fixed block 2 Between, the first fixed block 1 and the movable block 3 are connected by a hinge device 4, the movable block 3 and the second fixed block 2 are connected by a latch device 5, and the first fixed block 1 and the second fixed block 2 are provided with In the docking device 7 , the movable block 3 is separated from the second fixed block 2 and stored in the cavity formed between the first and second fixed blocks 1 and 2 .

The hinge device includes a first hinge arm 41 and a second hinge arm 42 , and the two hinge arms are connected by a hinge seat 43 and a pin shaft 44 .

The mating surfaces of the first hinge arm 41 and the second hinge arm 42 are provided with bosses 45 that engage with each other.

The tail end of the first hinge arm 41 and the second hinge arm 42 is provided with a hook 46 , and the hook 46 is hooked and fixed in the fixed block or the movable block 3 .

The first hinge arm 41 and the second hinge arm 42 are integrally fixed with the fixed block or the movable block by in-molding.

The movable block 3 includes a first movable block 31 and a second movable block 32 , and the two movable blocks are connected by a hinge device 4 .

The latch device 5 includes a latch head 51 and a latch seat 52 , the latch head 51 is inserted into the fixing hole 53 of the latch seat 52 , and the relative position between the two is fixed by a locking pin 54 .

The latch head 51 is provided with a locking hole 55 , and the locking pin 54 is inserted into the locking hole 55 to be fixed after passing through the slide groove 56 on the latch seat 52 .

The docking device 7 is a boss 71 and a groove 72 arranged on the docking surface of the first fixing block 1 and the second fixing block 2 . After the helmet is opened, the boss 71 is inserted into the groove 72 for docking.

Working principle: In this case, the helmet body is divided into the first fixed block 1, the second fixed block 2, and the movable block 3, between the first fixed block 1 and the second fixed block 2, between the first fixed block 1 and the movable block The blocks 3 are connected by a hinge device 4 , and the movable block 3 and the second fixed block 2 are connected by a latch device 5 . When the user needs to fold the helmet, the movable block 3 is separated from the second fixed block 2, and the hinge device between the fixed block and the movable block can make the two move mutually, so that the first fixed block and the second fixed block There is relative movement between them, and there is relative movement between the movable block and the fixed block. After separation, the movable block is accommodated inwardly so that it is accommodated in the cavity formed between the first and second fixed blocks 1 and 2. The stored helmet can effectively reduce the volume, so that it is convenient for the user to carry.

When the user needs to use the helmet, the fixed block and the movable block are opened outwards, and the latch head 51 is inserted into the fixed hole 53 of the latch seat 52, and the locking pin 54 is passed through the chute 56 on the latch seat 52, and then inserted It is fixed in the locking hole 55. The latch device is used to lock the relative distance between the fixed block and the movable block, thereby completing the recovery of the helmet. Compared with traditional helmets, the helmet in this case can be folded when not in use, thereby reducing the volume of the helmet and making it easy to carry. When it needs to be used, it can be restored quickly and conveniently. While satisfying its normal use, it is convenient for users to carry, so it can be widely used.
