Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a helmet with vehicle power supply function. Background Technology

[0002] The trend towards multi-functional helmets is a current hot topic in the industry, with electronic functions constantly evolving and becoming more abundant, such as Bluetooth communication, camera functions, lighting functions, and head-up displays. The increasing power and integration of helmet features have led to a significant increase in power consumption, posing new challenges and requirements for battery power technology.

[0003] In related technologies, devices with such multiple functions require more or larger batteries for power, making helmets exceptionally heavy. This increased weight not only places a physical burden on the rider but may also affect riding comfort and safety. Furthermore, motorcycles are more prone to accidents. Multiple or large-capacity batteries are more susceptible to rupture, deformation, or electrical short circuits when subjected to strong mechanical impacts. This damage not only disrupts the battery's physical structure but may also cause internal chemical leaks, increasing the risk of fire and explosion.

[0004] Therefore, it is necessary to develop a new type of helmet to improve some of the problems mentioned above in the relevant technology. Utility Model Content

[0005] The purpose of this invention is to provide a helmet with vehicle power supply function, which can achieve lightweight and safe operation of a multi-functional helmet with multiple devices.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] This utility model provides a helmet with vehicle power-taking function, including a helmet body, an electrical device, a power supply component, and a power-taking component; the electrical device is disposed on the helmet body; the electrical device is connected to the power supply component to obtain operating power; the power-taking component is used to obtain vehicle power and deliver it to the power supply component; wherein, the power supply component and the power-taking component are respectively disposed on the inner and outer sides of the helmet body, respectively, to deliver power in a manner that separates the helmet body.

[0008] Furthermore, at least two of the electrical devices are distributed on the helmet body, and the electrical devices are connected together to the power supply component to achieve unified power supply.

[0009] Furthermore, the helmet body is provided with contacts, and the power supply component and the power collection component transmit electrical energy through contact with the contacts.

[0010] Furthermore, the power supply component and the power extraction component transmit electrical energy through the electromagnetic induction of the coil.

[0011] Furthermore, the coil of the power-collecting component is a flexible coil, which allows the coil to match and conform to the outer contour shape of the helmet when connected to the helmet body.

[0012] Furthermore, the helmet body is provided with a protective part, which is disposed on the outer surface of the helmet body and covers the connection position between the power receiving component and the helmet body, for forming an accommodating chamber with an opening between the protective part and the helmet body, so as to allow the power receiving component to be inserted or removed.

[0013] Furthermore, the protective part protrudes from the outer surface of the helmet.

[0014] Furthermore, a groove is provided at the connection position between the helmet body and the power-collecting component, and the outer surface of the protective part and the outer surface of the helmet body have a smooth transition and form a single curved surface.

[0015] Furthermore, the power supply component and the power extraction component are positioned by magnetic attraction.

[0016] Furthermore, the power-collecting component is connected to the outer surface of the back of the head region on the helmet.

[0017] Furthermore, the power supply component includes a battery and wires, and the electrical devices are connected to the battery via the wires, wherein the battery is a lithium battery or a nickel-metal hydride battery, and the battery has a capacity greater than or equal to 250 mAh and less than or equal to 1000 mAh.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this invention, the electrical device is connected to the power supply component, and the power supply component directly obtains vehicle power to supply the electrical device through the power-taking component. This direct power extraction from the vehicle reduces battery capacity, which is beneficial for achieving a lighter helmet. Furthermore, since the power supply component and the power-taking component are not in direct contact but transmit power through the helmet's body, this power supply layout makes it easier to detach the power-taking component using the impact force of a collision in the event of a driving accident, reducing the safety hazard caused by continuous charging when the battery is damaged in a collision. Moreover, this method of obtaining power from the vehicle, which reduces battery capacity, also improves the helmet's electrical safety.

[0020] 2. This utility model connects the electrical devices together to the power supply component, and the power supply component directly obtains vehicle power to supply the electrical devices, so that the power supply component can provide unified power supply for at least two electrical devices, reducing the number of batteries. In the case of realizing the helmet's multi-functionality through multiple electrical devices, it is conducive to further lightweighting of the helmet.

[0021] 3. This invention connects the power supply component and the power collection component through contact or electromagnetic induction, enabling rapid connection between them and facilitating easy separation of the helmet upon impact, thus improving electrical safety.

[0022] 4. This utility model solves the problem of the coil not fitting the helmet shape during connection by designing the coil of the power taking component as a flexible coil. Without changing the original shape of the helmet, it reduces the positional deviation between coils and improves the electromagnetic field coupling effect, which balances the head protection safety and the efficiency of coil electromagnetic induction.

[0023] 5. In this utility model, the helmet body is provided with a protective part, which covers the connection position between the power receiving component and the helmet body at certain intervals, forming a receiving chamber between the helmet body and the protective part. This allows the power receiving component to be inserted into the receiving chamber through the opening and supply power to the power supply component. This method of inserting into the receiving chamber to supply power effectively protects the functional stability between the power receiving component and the power supply component, reducing the possibility of power supply disconnection due to external object collisions. Since the power receiving component is connected to the vehicle for power, the reasonable length design of the power receiving component ensures that the power receiving component will not detach when the driver is wearing the helmet and in the driving position of the vehicle due to its length limitation. In this case, external object collisions during driving are the main cause of power supply disconnection. The protective part effectively reduces this risk of disconnection. In the event of a driving accident, the driver is removed from the driving position, and the power receiving component can be easily detached from the opening of the receiving chamber due to its length limitation. This addresses both the prevention of detachment under normal driving conditions and the ease of detachment in the event of an accident, solving two contradictory technical problems simultaneously.

[0024] 6. This invention connects the power-collecting component to the helmet body on the outer surface of the back of the head. Since the back of the helmet body is relatively flat, this helps the electromagnetic coil maintain a relatively planar shape, maximizing charging efficiency. Furthermore, the back of the helmet body experiences less wind resistance, reducing the risk of wind disrupting the connection between the power-collecting component and the helmet body.

[0025] 7. This utility model obtains power from the vehicle through a power-taking component and supplies energy. Combined with the selection of lithium batteries or nickel-metal hydride batteries with high energy density for the power supply component, the capacity ranges from greater than or equal to 250 mAh to less than or equal to 1000 mAh. While meeting the power demand of the electrical equipment, it can greatly reduce the battery capacity of the power supply component and reduce the battery weight compared with the prior art, thus achieving further lightweighting of the helmet.

[0040] In this embodiment, the outer side of the helmet body 1 refers to the electrical equipment 5 being directly disposed on the outer surface of the helmet body 1, or indirectly connected to the outer surface of the helmet body 1 through other components.

[0041] In this embodiment, the inner side of the helmet body 1 refers to the electrical device 5 being directly disposed on the inner surface of the helmet body 1, or embedded in the cushioning material.

[0042] In this embodiment, the electrical device 5 can be installed in the area near the neck, the back of the head, the top of the head, the forehead, the side of the forehead, or the chin guard area of ​​the helmet body 1.

[0043] In this embodiment, the electrical device 5 can be a camera device. The camera device can be set on the outer surface of the helmet 1 to directly capture the external environment, or set on the inner surface of the helmet 1 to capture the external environment by making holes in the helmet 1 to allow light to pass through the helmet 1.

[0045] In another embodiment, the helmet may be a single-layer structure consisting only of the helmet body 1.

[0046] In this embodiment, the power supply component is located inside the helmet body 1, and the power extraction component is located outside the helmet body 1. The power supply component and the power extraction component are separated from the helmet body 1 and transmit electrical energy through electromagnetic induction of a coil.

[0047] In this embodiment, the power supply component includes a wire 41 and a first coil module 21 for electromagnetic induction. The first coil module 21 includes a receiving coil and other auxiliary circuits that work in conjunction with the coil, such as rectification and filtering, communication or management circuits. The power-consuming device 5 is connected to the first coil module one by one through the wires 41 set on the helmet 1 to obtain power.

[0048] In this embodiment, the first coil module 21 can be disposed on the inner surface of the helmet body 1 or embedded in the cushioning material.

[0049] In this embodiment, the receiving coil can be a planar coil, disposed on the partially planar inner surface of the helmet 1. The partially flat inner surface of the helmet 1 can be a flat surface of the back of the head, the side of the forehead, or the chin guard area of ​​the helmet 1.

[0050] In another embodiment, the receiving coil may be an arc-shaped coil disposed on the partially arc-shaped inner surface of the helmet body 1. The partially arc-shaped inner surface of the helmet body 1 may be the posterior head region, the region transitioning from the top of the head to the posterior head region, the region transitioning from the posterior head region to the near-neck region, or the region transitioning from the posterior head region to the lateral forehead regions on both sides.

[0052] In this embodiment, the second coil module 22 can be directly connected to the position on the outer surface of the helmet 1 corresponding to the first coil module 21, or it can be indirectly connected from the outside of the helmet 1 through a connection structure.

[0053] In this embodiment, the transmitting coil is connected to the outer surface of the helmet 1 through a connecting structure. The connection position of the transmitting coil to the outer surface of the helmet 1 corresponds to the position of the receiving coil inside the helmet 1, so that electromagnetic induction occurs between the transmitting coil and the receiving coil to transmit electrical energy, thereby realizing the circuit connection between the electrical equipment 5, the power supply component, the power collection component and the vehicle.

[0054] In this embodiment, the outer surface of the helmet 1 is provided with a structure that cooperates with the connecting structure to achieve quick disassembly and assembly between the two, and to enable the helmet 1 to be quickly separated from the connecting structure in the event of an accident. The connecting structure can be a snap-fit ​​connection, a spring snap ring connection, an elastic pin connection, or a clamp connection, and this utility model does not limit it in this regard.

[0055] In this embodiment, the transmitting coil of the power-harvesting component is a flexible coil, so that when the coil is connected to the helmet 1, it can match and fit the outer contour shape of the helmet 1.

[0057] In this embodiment, the shape of the receiving coil varies with its placement position; that is, the shape of the receiving coil is determined by the shape of the helmet 1 at its placement position. The material of the transmitting coil has good flexibility and can be enameled wire, Litz wire, or other flexible substrates, and is protected by a flexible encapsulation shell. When the second coil module 22 is connected to the outer surface of the helmet 1, it can change with the outer contour shape of the helmet 1.

[0058] For example, the inner and outer contours of the posterior head region of the helmet 1 are both arc-shaped surfaces. The receiving coil is disposed on the inner surface of the posterior head region of the helmet 1, and the receiving coil is an arc-shaped coil. The transmitting coil is connected to the outer surface of the posterior head region of the helmet 1.

[0059] In this embodiment, the power source 43 can be a device that matches the vehicle power system, vehicle charger, vehicle wireless charger, cigarette lighter, or vehicle output interface. Specific implementation methods can be achieved through conventional technical means known to those skilled in the art, and will not be described in detail here.

[0062] In this embodiment, the helmet may not include a battery or a similar energy storage module. The vehicle power supply directly supplies the electrical equipment, and the electrical equipment is powered off after the power taking component is detached from the helmet body 1.

[0063] Example 2

[0064] The basic structure of this embodiment is the same as that of embodiment 1, the difference being that the coil module in embodiment 1 is replaced by a contact connection module, such as... Figure 4 and Figure 5As shown, the helmet body 1 is provided with a contact structure, the power supply component is located inside the helmet body 1, and the power extraction component is located outside the helmet body 1. The power supply component and the power extraction component are separated from the helmet body 1 and transmit electrical energy through the contact structure on the helmet body 1.

[0065] In this embodiment, the power supply component includes a wire 41 and a first contact connection module 31. The first contact connection module 31 includes auxiliary circuits, such as rectification and filtering, communication or management circuits. The helmet body 1 is provided with a contact structure that penetrates the wall of the helmet body 1. The electrical device 5 is connected to the first contact connection module 31 one by one through the wires 41 provided on the helmet body 1. The first contact connection module 31 is connected to the contact structure to obtain electrical energy.

[0066] In this embodiment, the contact structure can be directly plugged into, welded to, crimped to, or spring-pressed to the first contact connection module 31, and this utility model does not impose any restrictions on this.

[0067] In this embodiment, the power supply component includes a power source 43, a wire 41, and a second contact connection module 32. The structure of the second contact connection module 32 is similar to that of the first contact connection module 31. The power source 43 is connected to the vehicle power supply, and the second contact connection module 32 is connected to the power source 43 through the wire 41 to obtain electrical energy.

[0068] In this embodiment, the first contact connection module 31, the contact structure, and the contact connection module are connected in sequence to realize the circuit connection between the electrical equipment 5, the power supply component, the power collection component, and the vehicle.

[0069] Example 3

[0070] The basic structure of this embodiment is the same as that of Embodiment 1 or Embodiment 2, the difference being that the power supply component in this embodiment also includes a battery 42, such as... Figure 6 As shown, the power supply component obtains electrical energy from the power receiving component and stores it in the battery 42. The electrical devices 5 are connected to the batteries 42 of the power supply component one by one through the wires 41.

[0071] In this embodiment, battery 42 is a lithium battery or a nickel-metal hydride battery.

[0072] In this embodiment, the capacity of battery 42 is greater than or equal to 250 mAh and less than or equal to 1000 mAh.

[0073] Specifically, the capacity of battery 42 can be 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950 or 1000 mAh.

[0074] Example 4

[0075] This embodiment is an improvement on embodiment 1 or embodiment 2. The improvement lies in that the helmet body 1 in this embodiment is further provided with a protective part 6, such as... Figure 7 As shown, the protective part 6 is disposed on the outer surface of the helmet body 1 and covers the connection position between the power supply component and the helmet body 1. The protective part 6 protrudes from the outer surface of the helmet body 1 and is used to form an accommodating chamber with an opening between the protective part 6 and the helmet body 1, so that the second coil module 22 or the second contact connection module 32 on the power supply component can be inserted or disengaged in the event of an accident.

[0076] In this embodiment, the protective part 6 includes a connector 61 and a shield 62. The shield 62 is connected to the outer surface of the helmet 1 through the connector 61. A certain gap is left between the shield 62 and the outer surface of the helmet 1 to form a receiving chamber.

[0077] In this embodiment, the specific location of the connector 61 is determined by the connection position between the power supply component and the helmet 1, and it can be located around the connection position between the power supply component and the helmet 1.

[0078] In this embodiment, the power supply component and the power take-up component are respectively disposed on the inner and outer sides of the back of the head region of the helmet 1. The connector 61 can be disposed at any position around the back of the head region, such as the area where the back of the head region transitions to the top of the head region, the area where the back of the head region transitions to the side of the forehead region, or the area where the back of the head region transitions to the near neck region. The shield 62 is disposed on the connector 61 and extends in the direction of the connection position between the power take-up component and the helmet 1, and covers the connection position between the power take-up component and the helmet 1, so that when the power take-up component is connected to the helmet 1, part of the power take-up component is accommodated in the receiving cavity. Specifically, the second coil module 22 or the second contact connection module 32 and part of the wire 41 can be accommodated in the receiving cavity. At this time, the communication path between the receiving cavity and the outside is only blocked by the connector 61. Except for the location of the connector 61, any other location can serve as an opening in the receiving cavity, so as to facilitate the insertion of the power take-up component or its removal from the receiving cavity in case of an accident.

[0079] In another embodiment, such as Figure 8 As shown, the connector 61 surrounds the connection position between the power-receiving component and the helmet 1, and has an opening only in the direction from the back of the head to the neck area, so that the power-receiving component can be dislodged from the receiving chamber from below in the event of an accident.

[0080] In another embodiment, a groove 7 is provided at the connection position between the helmet body 1 and the power-gathering component. The protective part 6 only includes a shielding member 62. One end of the shielding member 62 is disposed on one side of the opening of the groove 7, and the other end extends to cover and cover the opening of the groove 7, so that the internal space of the groove 7 forms an accommodating chamber. The contour shape of the shielding member 62 matches the contour shape of the outer surface of the helmet body 1, so that the outer surface of the protective part 6 and the outer surface of the helmet body 1 have a smooth transition and form a single curved surface. The groove 7 extends in one or more directions and exceeds the coverage area of ​​the shielding member 62 to form the opening of the accommodating chamber.

[0081] In another embodiment, the groove 7 extends from the back of the head region of the helmet 1 toward the neck region and beyond the coverage of the shield 62, allowing the power-collecting component to be inserted along the extension path of the groove 7 or disengaged from the receiving chamber in the event of an accident.

[0082] Example 5

[0083] The basic structure of this embodiment is the same as that of embodiment 1 or 2. The difference is that in this embodiment, the power supply component and the power taking component are positioned by magnetic attraction.

[0084] In this embodiment, the first coil module 21 or the first contact connection module 31 of the power supply component is fixedly disposed inside the helmet body 1. A magnet array is provided at the connection position between the helmet body 1 and the power taking component. The second coil module 22 or the second contact connection module 32 is provided with another matching magnet array, so that the power taking component can be automatically attracted and positioned when it is close to the helmet body 1, so that the first coil module 21 and the second coil module 22, or the first contact connection module 31 and the second contact connection module can be accurately positioned.

[0085] Example 6

[0086] The basic structure of this embodiment is the same as that of embodiment 1 or 2. The difference is that at least two electrical devices are distributed on the helmet body and are connected together to the power supply component to achieve unified power supply.
