Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a cycling helmet. Background Technology

[0002] Bicycles and electric bicycles are common and convenient means of transportation, especially electric bicycles, which are popular due to their large travel radius and low price. However, electric bicycles are relatively fast, and according to relevant traffic regulations, riders must wear helmets (the most solid protective barrier for life during cycling). Falls during cycling can cause serious head injuries, and even when riding at low speeds along a gentle bike path, safety should not be ignored. The reason for wearing a cycling helmet is simple and important—to protect the head and reduce injury. Medical research has found that wearing a helmet while cycling can prevent 85% of head injuries and significantly reduce the severity of injuries and the mortality rate in accidents. Half-helmets are available in road-only (without a visor) and road / mountain-bike dual-purpose (with a detachable visor). Women often wear ponytails, which can form a bun at the base of the hair, making it uncomfortable to wear a regular cycling helmet, leading many women to avoid them and creating a safety hazard.

[0003] Chinese utility model patent (authorization announcement number: CN204670460U, title: Women's Cycling Helmet) includes a helmet body that covers the top, sides, and back of the head, with the back of the head covered extending to the top of the neck. An inverted "U"-shaped notch is located at the center of the rear of the helmet body, extending upwards from the bottom edge for 10cm-15cm, with a width of 2cm-5cm. To improve the rigidity of the helmet, a connecting block is included. The sides of the notch at the rear of the helmet body are connected to the connecting block by rivets. However, during long-distance riding or riding under direct sunlight, the lack of a breathable structure leads to sweating, causing discomfort and potentially affecting vision. Furthermore, the prolonged dampness of the scalp promotes bacterial growth, leading to odor and scalp problems. Utility Model Content

[0004] The purpose of this invention is to provide a cycling helmet that overcomes the shortcomings of existing technology.

[0005] The objective of this utility model is achieved through the following technical solution: a cycling helmet, comprising a helmet body, wherein the helmet body has two pairs of ventilation holes, the helmet body is composed of an inner shell and an outer shell, a cavity is provided between the inner shell and the outer shell, the ventilation holes penetrate the inner shell and the outer shell, an arc-shaped plate is installed in the cavity, the arc-shaped plate is used to sequentially open and close the two pairs of ventilation holes, a sliding groove is provided on the outer shell, the same pair of ventilation holes are respectively located on both sides of the sliding groove, a push-pull tube is fixed on the arc-shaped plate, the push-pull tube is slidably installed in the sliding groove, a locking member is installed in the push-pull tube, the locking member is used to lock the arc-shaped plate.

[0006] Preferably, the locking element includes a bolt, a spring, and a ball bearing. The bolt is screwed onto the end of the push-pull tube away from the inner shell. The spring is compressed and installed between the bolt and the ball bearing. The ball bearing is pressed against the inner shell by the spring.

[0007] Preferably, a reinforcing rib is fixed inside the cavity, and the reinforcing rib is used to connect the inner shell and the outer shell.

[0008] Preferably, the inner shell has a locking groove for accommodating a portion of the ball bearings.

[0009] Preferably, the arc-shaped plate has a pair of adjustment holes, which are smaller than the vent holes. When the arc-shaped plate closes the second pair of vent holes, the adjustment holes are directly opposite the first pair of vent holes.

[0010] Preferably, the outer shell has a horizontal groove that communicates with the sliding groove. The horizontal groove and the sliding groove are in the shape of a "7". By inserting the push-pull tube into the horizontal groove, the arc-shaped plate closes the two pairs of ventilation holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The curved plate opens the ventilation holes to reduce head sweating and keep the head dry, avoiding odor and scalp problems. If it rains outside, the curved plate closes the ventilation holes to prevent rainwater from entering the helmet and causing the scalp temperature to drop too low, affecting blood circulation to the brain and causing headaches or dizziness.

[0024] like Figure 1 and 2 As shown, a cycling helmet includes a helmet body with two pairs of ventilation holes 1. The helmet body is composed of an inner shell 2 and an outer shell 3, with a cavity between the inner shell 2 and the outer shell 3. The ventilation holes 1 penetrate the inner shell 2 and the outer shell 3. An arc-shaped plate 4 is installed in the cavity, which is used to open and close the two pairs of ventilation holes 1 in sequence. A sliding groove 5 is provided on the outer shell 3, with the same pair of ventilation holes 1 located on both sides of the sliding groove 5. A push-pull tube 6 is fixed on the arc-shaped plate 4 and is slidably installed in the sliding groove 5. A locking device is installed in the push-pull tube 6 to lock the arc-shaped plate 4. The ventilation holes 1 are opened through the arc-shaped plate 4 to allow ventilation, reduce head sweating and keep the head dry, avoiding odor and scalp problems. If it rains outside, the ventilation holes 1 are closed through the arc-shaped plate 4 to prevent rainwater from entering the helmet and causing the scalp temperature to drop too low, affecting blood circulation to the brain and causing headaches or dizziness.

[0025] In this embodiment, as Figure 3 and 4 As shown, the locking mechanism includes a bolt 7, a spring 8, and a ball bearing 9. The bolt 7 is screwed onto the end of the push-pull tube 6 away from the inner shell 2. The spring 8 is compressed and installed between the bolt 7 and the ball bearing 9. The ball bearing 9 is pressed against the inner shell 2 by the spring 8. A locking groove 11 is provided on the inner shell 2. The locking groove 11 is used to accommodate part of the ball bearing 9. The sound made by the ball bearing 9 popping into the locking groove 11 can quickly determine whether the arc plate 4 has closed the ventilation hole 1, avoiding the need to remove the helmet and judge by visual inspection.

[0026] In this embodiment, as Figure 2 and 3 As shown, a reinforcing rib 10 is fixed inside the cavity. The reinforcing rib 10 is used to connect the inner shell 2 and the outer shell 3, making the helmet more robust and improving the safety of the helmet.

[0027] In this embodiment, as Figure 2 and 3As shown, a pair of adjustment holes 12 are provided on the arc plate 4. The adjustment holes 12 are smaller than the ventilation holes 1. When the arc plate 4 closes the second pair of ventilation holes 1, the adjustment holes 12 are directly opposite the first pair of ventilation holes 1. A horizontal groove 13 is provided on the outer shell 3. The horizontal groove 13 is connected to the sliding groove 5. The connected horizontal groove 13 and the sliding groove 5 form a "7" shape. By inserting the push-pull tube 6 into the horizontal groove 13, the arc plate 4 closes the two pairs of ventilation holes 1, so that the air intake of the helmet is adjustable to four levels (the first level has both pairs of ventilation holes 1 fully open, the second level has one pair of ventilation holes 1 fully open, the third level has the adjustment hole 12 fully open, and the fourth level has the ventilation hole 1 fully closed) to adapt to different environmental conditions.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
