Description

Technical Field

[0001] This utility model relates to the field of human safety protection equipment technology, specifically a ventilated smart safety helmet. Background Technology

[0002] A helmet is a protective gear used to protect the head from injury, widely used in military, construction, mining, sports, and daily transportation. Helmets vary in design and function depending on the specific use case and requirements. With technological advancements, helmet designs and functions will become more intelligent and diverse.

[0003] A typical helmet consists of a shell, liner, ventilation holes, and straps. The shell is located inside the helmet and provides comfort and cushioning to reduce direct impact to the head. The straps are connected to both sides of the shell and have buckles to secure the helmet in place. The ventilation holes are located on the shell to help dissipate heat from the head. When in use, the helmet is placed on the user's head, and the straps on both sides are connected via buckles so that the liner can be pressed tightly against the top of the user's head.

[0004] However, because the size of the ventilation holes cannot be adjusted, it can cause discomfort to the user's head in low temperatures or rainy weather, affecting the comfort of using the helmet.

[0005] Based on this, the present invention designs a ventilated smart safety helmet to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustment device is provided on the front and rear sides of the cap shell, the adjustment device including several ventilation holes, a knob, and blocking blocks. The knob is rotatably mounted on the cap shell, and several blocking blocks are provided, fixedly connected to the side of the knob. Several pressing blocks are fixedly provided on the side of the blocking block near the cap shell. The ventilation holes are opened on the cap shell and distributed around the knob, forming a flow channel between the two ventilation holes. When the blocking block rotates above the ventilation hole, the pressing blocks block the ventilation hole.

[0007] By adopting the above technical solution, when the helmet is worn on the user's head, cold air enters the helmet through the ventilation holes on the front and back sides. As the cold air flows, it carries away the heat from the user's head, allowing the helmet to dissipate heat. When the helmet needs to be kept warm or waterproof, by turning the knob, the shield is rotated above the ventilation hole, so that the pressing block on the shield is pressed against the ventilation hole, blocking the ventilation hole. Water and cold air cannot enter the helmet through the ventilation hole, thus giving the helmet a warm and waterproof effect and improving the comfort of using the helmet.

[0008] Preferably, a plurality of limiting blocks are fixedly provided on the cap shell, and an adhesive layer is provided on the surface of the limiting blocks. The limiting blocks are located between two ventilation holes. When the pressing block rotates away from the ventilation hole, the pressing block adheres to one side of the ventilation hole.

[0009] By adopting the above technical solution, when the collateral block rotates to the side away from the ventilation hole, the ventilation hole resumes its ventilation function, and the collateral block is adhered to the limiting block, so that the knob is limited and will not rotate arbitrarily, thus avoiding the ventilation hole being affected during use.

[0010] Preferably, the two sides of the pressing block are provided as inclined surfaces, and the inclined surfaces of the pressing block are inclined toward the side facing the ventilation hole.

[0011] By adopting the above technical solution, the pressure block can easily enter and exit the ventilation hole along the rotation direction of the knob, making the adjustment device easier and more convenient to use.

[0012] Preferably, the adjustment device has several guide grooves above it, the guide grooves are arched upward in the middle, and the two sides of the guide grooves extend to both sides of the adjustment device.

[0013] By adopting the above technical solution, when encountering rainy weather, the water flows down along the cap and then down along both sides of the guide groove, reducing the water flow through the regulating device and further improving the waterproof effect of the device.

[0014] Preferably, two adjustment devices are provided on the front and rear sides of the cap.

[0015] By adopting the above technical solutions, the ventilation area of ​​the helmet is increased, thereby improving the helmet's ventilation effect.

[0016] In summary, this application has the following beneficial technical effects: By adopting the above technical solution, when the helmet is worn on the user's head, cold air enters the helmet through the ventilation holes on the front and rear sides. As the cold air flows, it carries away the heat from the top of the user's head, allowing the helmet to dissipate heat. When the helmet needs to be kept warm or waterproof, by turning the knob, the shielding block is rotated above the ventilation hole, so that the pressing block on the shielding block is pressed against the ventilation hole, thus blocking the ventilation hole. Water and cold air will not enter the helmet through the ventilation hole, giving the helmet the effect of keeping warm and waterproof, and improving the comfort of using the helmet.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] A ventilated smart safety helmet includes a helmet shell 1. An adjustment device 2 is arranged opposite to the front and rear sides of the helmet shell 1. The adjustment device 2 includes a plurality of ventilation holes 3, a knob 7, and a blocking block 5. The knob 7 is rotatably mounted on the helmet shell 1. A plurality of blocking blocks 5 are provided and are fixedly connected to the side of the knob 7. A plurality of pressing blocks 6 are fixedly provided on the side of the blocking block 5 near the helmet shell 1. The ventilation holes 3 are opened on the helmet shell 1 and are distributed around the knob 7. A flow channel is formed between the two ventilation holes 3.

[0026] When in use, the helmet is worn on the user's head, and cool air enters the helmet through the ventilation holes 3 on the front and back sides. The airflow quickly passes through the helmet, carrying away heat from the head and keeping the head dry and comfortable, allowing the helmet to dissipate heat. When the helmet needs to be kept warm or waterproof, the knob 7 is turned, causing the shielding block 5 to rotate from the shell 1 to above the ventilation hole 3. Part of the pressing block 6 enters the ventilation hole 3 and presses against it, blocking the ventilation hole 3 and preventing water and cold air from entering the helmet through the ventilation hole 3. This gives the helmet a warm and waterproof effect, improving the comfort of using the helmet.

[0027] Several limiting blocks 8 are fixedly installed on the helmet shell 1. The surface of the limiting blocks 8 is provided with an adhesive layer. The limiting blocks 8 are located between two ventilation holes 3. The two sides of the pressing block 6 are set as inclined surfaces. The inclined surfaces of the pressing block 6 are inclined towards the ventilation hole 3. When the knob 7 is turned, the blocking block 5 is moved away from the ventilation hole 3. The inclined surface on the pressing block 6 presses against the ventilation hole 3, so that the pressing block 6 can be separated from the ventilation hole 3. Until the pressing block 6 is completely separated from the ventilation hole 3, the ventilation hole 3 returns to the ventilation state. The knob 7 continues to be turned until the pressing block 6 touches the limiting block 8. The adhesive layer on the limiting block 8 adheres to the pressing block 6, so that the pressing block 6 will not move easily. The knob 7 stops turning, so that the ventilation function of the helmet will not be affected, and the stability of the adjustment device 2 is improved.

[0028] Several guide grooves 4 are provided above the adjustment device 2. The guide grooves 4 are arched upward in the middle and extend to both sides of the adjustment device 2. In rainy weather, water flows down the shell 1. The water flowing towards the adjustment device 2 will first encounter the guide grooves 4 and then flow down from both sides of the adjustment device 2 along the direction of the guide grooves 4, reducing the amount of water flowing through the adjustment device 2 and further improving the waterproof effect of the device. The adjustment device 2 is provided with two on the front and two on the back of the shell 1, which increases the number of ventilation holes 3 and increases the airflow area. The user's head can come into contact with more cool air, which further improves the heat dissipation effect of the helmet.

[0029] The implementation principle of this embodiment is as follows: When the helmet is worn on the user's head, cold air enters the helmet through the ventilation holes 3 on the front and rear sides. The airflow quickly passes through the helmet, carrying away heat from the head and keeping the head dry and comfortable, allowing the helmet to dissipate heat. When the helmet needs to be kept warm or waterproof, the knob 7 is turned, causing the pressure block 6 to separate from the limiting block 8. The blocking block 5 rotates from the shell 1 to above the ventilation hole 3, and the pressure block 6 enters the ventilation hole 3. The inclined surfaces on both sides of the pressure block 6 abut against the ventilation hole 3, blocking the ventilation hole 3 and preventing water and cold air from entering the helmet through the ventilation hole 3.
