Description

Technical Field

[0001] The present invention relates to the technical field of bicycle helmets, and more particularly to a safety helmet for bicycles. Background Art

[0002] Falling while riding can cause great damage to the head. Even if the rider is riding at a lower speed along a bike path with a smooth slope, safety issues cannot be ignored. Currently, most helmets can only protect the wearer's head after an accident, prevent or reduce damage, and reduce the wearer's injury level in an accident. However, when a rider falls, the neck may also be injured due to the fall.

[0003] Chinese patent application number 202421455307.6 discloses a cycling helmet with an airbag, including a helmet body, wherein an extension is provided at the lower edge of one end of the helmet body, a mounting groove is provided on the outer side of the extension, an airbag compartment is installed in the mounting groove, an air pump compartment is installed above the airbag compartment, an air pump body is provided in the air pump compartment, a trigger device is installed at the end of the air pump body, and an airbag bag located in the airbag compartment is installed on the trigger device. The patent detects the change of the center of gravity of the rider through the cooperation between the helmet body, the air pump compartment, the air pump body, the airbag compartment and the trigger device, and then turns on the air pump body to inflate the airbag in the airbag compartment, so that the head and neck of the rider are protected after the airbag is deployed, thereby avoiding sudden accidents. The invention provides protection for the safety of the rider and reduces the risk of injury. However, the patent detects the riding status of the rider through the cooperation of power supply, sensor, etc. When the sensor fails, the airbag cannot be ejected normally to provide effective protection for the rider. Carrying an air pump will greatly increase the weight of the helmet. Moreover, when the rider is not wearing a helmet and the helmet accidentally falls, the trigger device may misjudge and cause the airbag to open directly. What needs more attention is that, similar to the above-mentioned prior art, the air pump needs a certain amount of time to complete the inflation protection of the airbag by using the air pump to inflate the airbag. However, the collision in reality often occurs in an instant. For such a violent collision that occurs in an instant, the air pump often does not have time to inject enough gas into the airbag to achieve the protective effect, resulting in unsatisfactory protection effect for the rider.

[0004] Therefore, the present invention proposes a safety helmet for bicycles to solve the above problems. Summary of the invention

[0005] In order to overcome the above defects of the prior art, an embodiment of the present invention provides a safety helmet for a bicycle to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A safety helmet for a bicycle, comprising: a helmet body, a detection component, an actuator, and a neck protection component. The neck protection component includes an airbag disposed inside the helmet body, and an inflation part is provided at the air inlet of the airbag; the detection component includes a limiting mechanism and a buffering mechanism. When the rider does not wear the helmet, the limiting mechanism can prevent the neck protection component from being accidentally triggered; when the rider wears the helmet, the limiting mechanism is released. When the rider tilts or decelerates, the buffering mechanism can prevent the neck protection component from being accidentally triggered; when the rider falls off the bike, the detection component can cause the actuator to trigger the inflation part to inflate the airbag.

[0007] Preferably, the limiting mechanism includes a detection cylinder and a limiting member disposed inside the helmet body. An inertial sensing member is provided inside the detection cylinder, a limiting groove is provided at the inner top end of the detection cylinder, the limiting member is slidably connected to the detection cylinder, and the limiting member can cooperate with the limiting groove by sliding to limit the inertial sensing member. The buffering mechanism includes a detection groove and a buffering member provided inside the detection cylinder. The inertial sensing member can displace inside the detection groove by inertia. When the inertial sensing member impacts the buffering member, the buffering member can buffer the inertial sensing member.

[0008] Preferably, a second wedge block is provided inside the helmet body. One end of the limiting member away from the inertial sensing member is fixedly connected to a first wedge block, and the second wedge block can squeeze the first wedge block by sliding.

[0009] Preferably, a sliding groove is provided inside the helmet body. The second wedge block is slidably connected to the sliding groove. A second elastic member is provided inside the sliding groove. One end of the second elastic member is fixedly connected to the second wedge block, and the other end of the second elastic member is fixedly connected to the inner wall of the sliding groove. There are two second wedge blocks, which are mirror-symmetrically arranged at both ends of the sliding groove.

[0010] Preferably, a locking strap is provided inside the helmet body. There are two locking straps, which are respectively fixedly connected to the second wedge blocks. The locking straps can slide inside the helmet body, and a locking strap groove for the locking straps to slide is provided inside the helmet body.

[0011] Preferably, a first electrode plate is slidably connected inside the detection cylinder, a second electrode plate is fixedly connected inside the detection cylinder, a first elastic member is provided inside the detection cylinder, one end of the first elastic member is fixedly connected to the end of the first electrode plate away from the second electrode plate, and the other end of the first elastic member is fixedly connected to the inner wall of the detection cylinder.

[0012] Preferably, the neck protection component further includes an airbag chamber provided on the helmet body, the airbag is arranged inside the airbag chamber, a protective shell is arranged outside the airbag chamber, the protective shell is detachably connected to the airbag chamber, and the protective shell is made of an elastic material.

[0013] Preferably, the actuator includes a power source and a wire group, the wire group is electrically connected to the power source in an electrical signal manner, the wire group is electrically connected to the inflation part in an electrical signal manner, the power source can energize the wire group to trigger the inflation part to inflate the airbag, and the first electrode plate and the second electrode plate are electrically connected to the power source in an electrical signal manner.

[0014] Preferably, the detection groove is of a conical structure, and the buffer members are multiple and are first arranged in an array on the side wall of the detection groove close to the bottom of the detection cylinder.

[0015] Preferably, the helmet body includes an inner liner and an outer liner, the inner liner is detachably connected to the outer liner, an installation groove for installing a fixing member is formed inside the outer liner, and the sliding groove is arranged inside the inner liner.

[0016] The technical effects and advantages of the present invention:

[0017] 1. When the rider falls off the vehicle, the inertial sensing member impacts the first electrode plate, causing the first electrode plate to contact the second electrode plate, so that the wire group is energized through the power source to trigger the gas generating member to eject the airbag to protect the rider's neck, preventing the problem that the airbag 41 cannot be effectively ejected due to sensor failure.

[0018] 2. When the rider does not wear the helmet, the two second wedge-shaped blocks squeeze the first wedge-shaped block, so that the limiting member and the detection cylinder limit the inertial sensing member, preventing the problem that when the rider does not wear the helmet and the helmet accidentally falls, it may be misjudged and the airbag is directly opened.

[0019] 3. The chemical material inside the inflation part reacts to generate gas, replacing the air pump, which is lighter in weight, thus reducing the burden on the head when wearing the helmet, and at the same time preventing the problem that the air pump often fails to inflate enough gas into the airbag.

[0020] 4. When the rider rides normally and has a slight tilt or deceleration, the buffer of the inertial sensing member by the buffer member makes the inertial sensing member unable to contact the first electrode plate and the second electrode plate by impact, thus preventing the problem that the detection component is misjudged and the airbag is ejected when the rider rides normally.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] During the actual production process, since the rider may also be injured in the neck due to a motorcycle accident, this embodiment is specifically invented to solve the above problems.

[0032] Please refer to Figures 1 to 7As shown in the figure, a safety helmet for a bicycle according to an embodiment of the present invention includes a helmet body 1, a detection component 2, an actuator 3, and a neck protection component 4. The neck protection component 4 includes an airbag 41 disposed inside the helmet body 1, and an inflation part 42 is provided at the air inlet of the airbag 41. The detection component 2 includes a limiting mechanism 26 and a buffering mechanism 27. When the rider does not wear the helmet, the limiting mechanism 26 can prevent the neck protection component 4 from being accidentally triggered. When the rider wears the helmet, the limiting mechanism 26 is released. When the rider tilts slightly or decelerates, the buffering mechanism 27 can prevent the neck protection component 4 from being accidentally triggered. When the rider falls off the bike, the detection component 2 can cause the actuator 3 to trigger the inflation part 42 to inflate the airbag 41. The actuator 3 includes a power supply 31 and a wire group 32. The wire group 32 is electrically connected to the power supply 31, and the wire group 32 is electrically connected to the inflation part 42. The power supply 31 can energize the wire group 32 to trigger the inflation part 42 to expand the airbag 41. Among them, the inflation part 42 generates nitrogen through the chemical reaction of chemical materials, such as a chemical mixture mainly composed of guanidine nitrate materials, etc. It is a prior art that the wire group 32 is energized to trigger the chemical reaction inside the inflation part 42, and thus will not be elaborated here.

[0033] Please refer to Figure 5 and Figure 6 As shown in the figure, the limiting mechanism 26 includes a detection cylinder 22 disposed inside the helmet body 1. The buffering mechanism 27 includes a detection groove 24 opened inside the detection cylinder 22. An inertial sensing member 23 is disposed inside the detection cylinder 22. When the rider wears the helmet and tilts, the inertial sensing member 23 can roll inside the detection groove 24 by inertia. A fixing member 21 is disposed inside the helmet body 1, and the detection cylinder 22 is fixedly connected inside the fixing member 21. A limiting member 25 is slidably connected inside the detection cylinder 22. One end of the limiting member 25 is in contact with the inertial sensing member 23. A limiting groove is provided at the inner top end of the detection cylinder 22. When the limiting member 25 slides to the extreme position towards the top of the detection cylinder 22, the limiting member 25 can cooperate with the limiting groove to limit the inertial sensing member 23.

[0034] Please refer to Figure 6 As shown in the figure, the detection groove 24 is a conical structure. A plurality of buffer members 241 are fixedly connected to the side wall of the detection groove 24 close to the bottom of the detection cylinder 22. When the inertial sensing member 23 impacts the buffer members 241, the buffer members 241 can buffer the inertial sensing member 23. There are a plurality of buffer members 241, and they are arranged in an array along the side wall of the detection groove 24.

[0035] Please refer to Figure 5 and Figure 6As shown, a first electrode plate 33 is slidably connected inside a detection cylinder 22, a second electrode plate 34 is fixedly connected inside the detection cylinder 22, a first elastic member 331 is arranged inside the detection cylinder 22, one end of the first elastic member 331 is fixedly connected to the end of the first electrode plate 33 away from the second electrode plate 34, the other end of the first elastic member 331 is fixedly connected to the inner wall of the detection cylinder 22, the first electrode plate 33 and the second electrode plate 34 are electrically connected to a power supply 31. Among them, when the first electrode plate 33 contacts the second electrode plate 34, the power supply 31 can energize the wire group 32. There are multiple first elastic members 331 and they are circumferentially arrayed along the side wall of the first electrode plate 33. This is the prior art and will not be elaborated here too much.

[0036] Please refer to Figure 4 and Figure 5 As shown, a chute 11 is formed inside a helmet body 1, a second wedge block 12 is slidably connected inside the chute 11, one end of a limiting member 25 extends out of a fixing member 21, a first wedge block 251 is fixedly connected to the end of the limiting member 25 extending out of the fixing member 21, and the second wedge block 12 can slide and press the first wedge block 251.

[0037] Please refer to Figure 5 As shown, a second elastic member 13 is arranged inside the chute 11, one end of the second elastic member 13 is fixedly connected to the second wedge block 12, the other end of the second elastic member 13 is fixedly connected to the inner wall of the chute 11, and there are two second wedge blocks 12 which are mirror - image arranged at both ends of the chute 11.

[0038] Please refer to Figure 4 As shown, a locking strap 14 is arranged inside the helmet body 1. There are two locking straps 14 which are respectively fixedly connected to the second wedge blocks 12. The locking straps 14 can slide inside the helmet body 1. A locking - strap groove for the sliding of the locking straps 14 is arranged inside the helmet body 1. The locking - strap groove cooperates with the locking straps 14. By pulling the two locking straps 14, the locking straps 14 can slide in the locking - strap groove, and the two locking straps 14 can cooperate with each other for locking. This is the prior art and will not be elaborated here too much.

[0039] Please refer to Figure 2 and Figure 3 As shown, the neck protection assembly 4 further includes an air - bag bin 43 arranged on the helmet body 1. An air bag 41 is arranged inside the air - bag bin 43. A protective shell 44 is arranged outside the air - bag bin 43. The protective shell 44 is snap - connected to the air - bag bin 43. When the protective shell 44 undergoes elastic deformation, the snap - connection part can be disengaged from the air - bag bin 43. This is the prior art and will not be elaborated here too much.

[0040] Please refer to Figure 2 and Figure 3As shown, the protective shell 44 is made of elastic material. When the protective shell 44 is impacted, it can undergo elastic deformation. When the protective shell 44 undergoes elastic deformation, the connection between the protective shell 44 and the airbag chamber 43 is disengaged from each other. The connection of the protective shell 44 is disengaged from the airbag chamber 43. The airbag 41 and the airbag chamber 43 are detachably connected. The inflation part 42 is fixedly connected to the air inlet of the airbag 41. For example, the outer wall of the air inlet of the airbag 41 is threadedly connected to the airbag chamber 43, and the outer wall of the inflation part 42 is threadedly connected to the inner wall of the air inlet of the airbag 41. When it is necessary to replace the airbag 41, the airbag 41 and the inflation part 42 are removed and a new airbag 41 and inflation part 42 are replaced. This is the prior art and will not be elaborated here.

[0041] As Figure 5 and Figure 7 As shown, the helmet body 1 includes an inner liner 15 and an outer liner 16. The inner liner 15 and the outer liner 16 are detachably connected to facilitate the installation of relevant components. An installation groove for installing the fixing member 21 is provided inside the outer liner 16. The sliding groove 11 is provided inside the inner liner 15. The detachable connection between the inner liner 15 and the outer liner 16 is the prior art and will not be elaborated here. An avoidance groove for the sliding of the first wedge block 251 is provided at the top of the inner liner 15.

[0042] During use, when the rider wears the helmet properly, the limiting member 25 is at the lower limit position of the detection cylinder 22. When the rider rides normally and experiences a slight tilt or deceleration, due to inertia, the inertial sensing member 23 slides along the side wall at the bottom of the detection groove 24 inside the detection cylinder 22 and touches the buffer member 241. The impact force of the inertial sensing member 23 is offset and it cannot roll to the first electrode plate 33. When the rider suddenly brakes, causing the inertial sensing member 23 to hit the first electrode plate 33, since there is a first elastic member 331 between the first electrode plate 33 and the detection cylinder 22, at this time, through the buffering of the buffer member 241, the impact force of the inertial sensing member 23 cannot make the first electrode plate 33 contact the second electrode plate 34. During normal riding or parking, when the rider's head tilts significantly and the riding speed is usually slow, the impact force provided by the inertial sensing member 23 due to inertia is insufficient, and it also cannot cause the first electrode plate 33 to contact the second electrode plate 34. When the rider falls off the bike, due to the large tilt angle of the helmet and the fast deceleration during the fall, the direction in which the inertial sensing member 23 rolls inside the detection groove 24 will form a certain angle with the side wall at the bottom of the detection groove 24, so that the inertial sensing member 23 no longer contacts the buffer member 241. When the inertial sensing member 23 rolls to hit the first electrode plate 33, since the impact force of the inertial sensing member 23 is not buffered, the inertial sensing member 23 drives the first electrode plate 33 to slide, so that the first elastic member 331 on the impacted side is stretched, so that the first electrode plate 33 contacts the second electrode plate 34, so that the power supply 31 can energize the wire group 32, so that the chemical materials inside the inflating part 42 react to release nitrogen and quickly fill the airbag 41, so that the airbag 41 expands rapidly, so that the protective shell 44 undergoes elastic deformation, so that the connection between the protective shell 44 and the airbag chamber 43 is disengaged, so that the airbag 41 pops out of the airbag chamber 43 to protect the rider's neck. When the rider falls off the bike, the inertial sensing member 23 hits the first electrode plate 33, causing the first electrode plate 33 to contact the second electrode plate 34, so that the wire group 32 is energized through the power supply 31 to trigger the inflating part 42 to pop out the airbag 41 to protect the rider's neck, preventing the problem that the airbag 41 cannot be effectively popped out when the sensor fails.

[0043] Embodiment 2

[0044] During actual use, it is found that when the rider does not wear the helmet and the helmet accidentally falls, it may be misjudged and the airbag may be directly opened. Further improvements are made on the basis of the above embodiments.

[0045] Based on the above embodiments, during use, in the initial state, the second elastic member 13 is relaxed, causing the two second wedge-shaped blocks 12 to move towards the center of the sliding groove 11, thereby causing the two second wedge-shaped blocks 12 to squeeze the first wedge-shaped block 251, causing the limiting member 25 to move upward to the extreme position inside the detection cylinder 22, so that the limiting member 25 cooperates with the limiting groove inside the detection cylinder 22 to limit the inertial sensing member 23. Thus, when the helmet is not worn, the inertial sensing member 23 is fixed and cannot move inside the detection cylinder 22. When the rider wears the helmet, the two lock belts 14 are tightened towards both sides to cooperate and lock. During the process of tightening the two lock belts 14, the two lock belts 14 drive the two second wedge-shaped blocks 12 to move away from the center of the sliding groove 11 respectively, causing the first wedge-shaped block 251 to move downward due to its own gravity, causing the limiting member 25 to move towards the lower extreme position of the detection cylinder 22, enabling the inertial sensing member 23 to move inside the detection cylinder 22 to detect whether the rider has fallen. By the two second wedge-shaped blocks 12 squeezing the first wedge-shaped block 251 when the helmet is not worn, the limiting member 25 and the detection cylinder 22 limit the inertial sensing member 23, preventing the problem that when the rider does not wear the helmet and the helmet accidentally falls, it may be misjudged and the airbag 41 is directly opened.

[0046] Embodiment 3

[0047] During actual use, it is found that carrying an air pump will significantly increase the weight of the helmet, and further improvements are made based on the above embodiments.

[0048] During use, by making the first electrode piece 33 and the second electrode piece 34 contact each other, the wire group 32 is energized through the power supply 31, causing the chemical materials inside the inflation part 42 to react, thereby generating gas to inflate the airbag 41, replacing the air pump, with a lighter weight and reducing the burden on the head when wearing the helmet.

[0049] It should be noted that for reuse, the airbag 41 and the inflation part 42 are designed to be detachable. When the airbag 41 is triggered, the airbag 41 can be disassembled, the airbag 41 and the inflation part 42 can be replaced, and reinstalled, and the helmet can continue to be used normally.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
