Description

Technical Field

[0001] This application relates to the field of lighting technology, and more particularly to a headlamp. Background Technology

[0002] A headlamp, as the name suggests, is a light worn on the head, a tool that frees up the hands for illumination. Headlamps are suitable for many situations, such as outdoor camping, night walking, night running, outdoor rescue, and caving.

[0003] In existing technology, headlamps are connected via a small support and a small pivot at the rear of the headlamp to support its rotation. On one hand, the headlamp itself has a certain weight, and the small pivot not only supports this weight but also enables its rotation, subjecting the pivot to significant shear forces. Furthermore, the small pivot limits the range of adjustment for headlamp rotation. Even if the small pivot were replaced with a larger one, it would increase the heat transfer efficiency between the headlamp and the headband, and increase the distance between them, thus increasing the leverage arm and disrupting the overall weight distribution of the headlamp. This would also negatively impact the user experience. Additionally, in existing technology, the power cord is located at the rear of the headlamp, requiring the end used for electrical connection to have a nearly 90-degree bend. Common sense dictates that this severely shortens the lifespan of the power cord, consequently affecting the headlamp's durability during long-term, continuous use.

[0004] In summary, the existing headlamp rotation adjustment range is limited, the durability of the headlamp rotation part is poor, and the durability of the headlamp power cord is also poor, thus there is room for further improvement. Utility Model Content

[0005] One of the objectives of this application is to provide a headlamp that can solve at least one of the defects in the aforementioned background art.

[0006] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a headlamp, comprising a lamp holder, a lamp head, a power cord, and a battery compartment. The lamp holder is C-shaped, and the lamp head is at least partially located within the lamp holder. One end of the lamp head is rotatably connected to one end of the lamp holder, and the other end of the lamp head is either rotatably connected to the lamp holder or rotatably connected to the power cord. The power cord is electrically connected to the lamp head, and the end of the power cord away from the lamp head is electrically connected to the battery compartment.

[0007] By adopting the above technical solution, the headlamp connects to the lamp holder at both ends, providing better support for the lamp head. Since the power cord also needs to connect to the lamp head, it is connected to the side of the lamp head to avoid bending. Furthermore, because the lamp head needs to rotate, the connection point between the power cord and the lamp head is designed to be the same as the connection point between the lamp head and the lamp holder to prevent the power cord from interfering with its rotation. This achieves excellent mechanical support for the lamp head and improves its rotation range by arbitrarily thickening the portion that does not affect its rotation, allowing the lamp head to rotate. By aligning the positions of the power cord, lamp holder, and lamp head, the power cord does not need to be bent, and the lamp holder and lamp head can have minimal volume. The lamp head's volume or shape does not need to be specifically designed for the connection between the power cord and the lamp head, allowing for a high degree of freedom in the lamp head's structure.

[0008] Preferably, the lamp holder includes a first connector, a second connector, and a first gasket. One end of the first gasket is connected to the first connector, and the other end is connected to the second connector. The first connector and the second connector are disposed opposite to each other. The lamp head is at least partially located between the first connector and the second connector, with one end connected to the first connector and the other end connected to the second connector. This configuration, through the design of the first connector, the second connector, and the first gasket, allows the lamp holder to have a minimal volume that allows connection to both ends of the lamp head, thereby reducing the overall weight of the headlamp.

[0009] Preferably, one end of the lamp holder is provided with a first damping shaft, which is connected to the lamp head. The other end of the lamp holder is provided with a second damping shaft, which is connected to one end of the power cord. The power cord is fixedly connected to the lamp head. With this configuration, one end of the lamp head is connected to one end of the lamp holder via the first damping shaft, the other end of the lamp holder is connected to the power cord via the second damping shaft, and the other end of the lamp head is fixedly connected to the power cord, allowing the lamp head and power cord to be rotatably connected via the lamp holder.

[0010] Preferably, one end of the lamp holder is provided with a first damping shaft, which is connected to one end of the lamp head. The other end of the lamp head is provided with a second damping shaft, which is connected to one end of the power cord. The power cord is fixedly connected to the lamp holder. With this configuration, one end of the lamp head is connected to one end of the lamp holder via the first damping shaft, and the other end of the lamp head is connected to the power cord via the second damping shaft. This allows the lamp head to rotate between the lamp holder and the power cord, while the power cord is fixed to the other end of the lamp holder, enabling the lamp head to rotate through the lamp holder and the power cord.

[0011] Preferably, the power cord includes a wire and connectors, with the connectors located at both ends of the wire. One connector is electrically connected to the battery compartment, and the other connector is electrically connected to the lamp holder. This configuration, by making the connectors a rigid material, allows them to act as a power transmission component between the lamp holder and the lamp base. Furthermore, the connectors are conductive, enabling the power stored in the battery compartment to be transferred to the lamp holder, maintaining its operation.

[0012] Preferably, the lamp holder is provided with heat dissipation fins. This design further improves the heat dissipation effect of the lamp holder through the heat dissipation fins. Preferably, the first connector has a first groove on the side away from the lamp head, and the second connector has a second groove on the side away from the lamp head. This arrangement can further reduce the weight of the lamp holder and optimize the overall configuration of the headlamp.

[0013] Preferably, the battery compartment is provided with a cover, the battery compartment has a third groove, and the cover has a second protrusion that engages with the third groove. This arrangement enhances the stability of the connection between the battery compartment and the cover.

[0014] Preferably, the battery compartment is provided with a connecting rod, and the cover is provided with a third connecting member, which is C-shaped and cooperates with the connecting rod. This arrangement allows the battery compartment and the cover to be rotatably connected, facilitating the replacement of the battery in the battery compartment and simplifying the connection between the battery compartment and the cover.

[0015] Preferably, the battery compartment is connected to a second gasket, which is positioned opposite to the first gasket; there is a gap between the second gasket and the battery compartment; the first gasket is provided with a first headband fixing buckle, and the second gasket is provided with a second headband fixing buckle, which is positioned opposite to the first headband fixing buckle. This arrangement facilitates the connection between the battery compartment and the headband fixing buckle, increases the user's comfort when wearing the headlamp, and improves the heat dissipation of the battery compartment by adjusting the distance between the lamp head and the battery compartment. The headband fixing buckle facilitates the connection between the gasket and the headband.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The headlamp connects to the lamp holder at both ends, providing superior support for the lamp head. Since the power cord also connects to the lamp head, it is connected to the side of the lamp head to prevent bending. Furthermore, because the lamp head needs to rotate, the connection point between the power cord and the lamp head is designed to prevent the power cord from interfering with rotation, similar to the connection point between the lamp head and the lamp holder. This design achieves excellent mechanical support for the lamp head and improves its rotation range by arbitrarily thickening the portion that doesn't affect rotation. The consistent positioning of the power cord, lamp holder, and lamp head eliminates the need for bending the power cord and minimizes the overall volume of the lamp holder and lamp head. This eliminates the need to specifically design the lamp head's size or shape for the power cord connection, allowing for a high degree of structural flexibility.

[0017] One end of the lamp holder is connected to one end of the lamp base via a first damping shaft, and the other end of the lamp base is connected to the power cord via a second damping shaft. The other end of the lamp holder is fixedly connected to the power cord, allowing the lamp holder and the power cord to rotate through the lamp base. Alternatively, one end of the lamp holder can be connected to one end of the lamp base via a first damping shaft, and the other end of the lamp holder can be connected to the power cord via a second damping shaft, allowing the lamp holder to rotate between the lamp base and the power cord. The power cord is fixed to the other end of the lamp base, allowing the lamp holder to rotate through the lamp base and the power cord. Attached Figure Description

[0020] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0022] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0024] One aspect of this application provides a headlamp, one preferred embodiment of which is, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the headlamp includes a lamp head 1, a lamp holder, a power cord 3, and a battery compartment 4. The lamp holder is generally C-shaped. The lamp head 1 is at least partially located between the lamp holder and the lamp head. One end of the lamp head 1 is provided with a first damping shaft, which is connected to one end of the lamp holder, allowing one end of the lamp head 1 to be rotatably connected to one end of the lamp holder via the first damping shaft. The other end of the lamp head 1 is provided with a second damping shaft, which is connected to the power cord 3. The power cord 3 is fixedly connected to the lamp holder, allowing the lamp head 1 to be rotatably connected to the power cord 3 via the second damping shaft. The axes of the first damping shaft and the second damping shaft are aligned, allowing the lamp head 1 to rotate freely within the lamp holder. The power cord 3 is also electrically connected to the lamp head 1. The end of the power cord 3 away from the lamp head 1 is electrically connected to the battery compartment 4, ensuring that the battery in the battery compartment 4 can supply power to the lamp head 1 via the power cord 3.

[0025] Specifically, the power cord 3 includes a wire and connectors. Both ends of the wire are connected to two connectors. One connector is electrically connected to the battery compartment 4, and the other is electrically connected to the lamp head 1. This improves the connection stability of the power cord 3 and prevents wear caused by rotation of the lamp head 1. Furthermore, the connection between the wire and the connector can be a plug-in joint or an integrated design. The connector can have a block-like structure, allowing it to electrically connect to both the lamp head 1 and the wire simultaneously, ensuring that electricity within the wire can be transmitted to the headlamp 1 through the connector.

[0026] As a supplement, the connector, acting as a transition carrier for the wire, should possess good conductivity and structural strength to ensure that electricity within the wire can be transferred to the connector. Therefore, in this application, the connector is made of rigid materials such as copper, aluminum, or alloys, which possess both conductive properties and high structural strength. This ensures that the connector can not only connect to the second damping shaft but also act as a shaft for transmitting rotational force. However, it should be noted that as the distance between the lamp holder 1 and the battery compartment 4 increases, the wire will be stretched. Therefore, to ensure that the wire can be designed to be longer and will not sag, the wire can be partially coiled to give it a certain degree of elasticity. The specific structure of the wire is prior art and will not be described in detail here, but it is necessary to ensure that the wire's stiffness is not too high to ensure that the wire can be coiled and obtain elasticity.

[0027] Furthermore, the connection between the lamp holder, lamp head 1, and power cord 3 can also be in other forms. In this embodiment, it is only necessary to connect one end of the lamp head 1 to the lamp holder, and connect the other end of the lamp head 1, the other end of the lamp holder, and the power cord 3 to a single point, and ensure that the power cord 3 and the lamp head 1 can be electrically connected. Preferably, one end of the lamp holder is provided with a first damping shaft, which is connected to one end of the lamp head 1, so that one end of the lamp holder is rotatably connected to one end of the lamp head 1 through the first damping shaft. The other end of the lamp holder is provided with a second damping shaft, which is connected to the power cord 3, so that the lamp holder and the power cord 3 can be rotatably connected through the second damping shaft. The power cord 3 and the lamp head 1 are fixedly connected, so that after the power cord 3 and the lamp head 1 are electrically connected, there will be no relative rotation or movement between the power cord 3 and the lamp head 1. Furthermore, the second damping shaft provided at one end of the lamp holder near the power cord 3 can also be rotatably connected to the lamp head 1, and the axis of the second damping shaft is provided with a through hole, so that the power cord 3 passes through the through hole and is electrically connected to the lamp head 1. At this time, the tightness of the connection between the power cord 3 and the through hole will not affect the rotation of the lamp head 1.

[0028] It should be noted that the first damping shaft and the second damping shaft in this application can be any type of damping shaft, as long as they can enable the rotational connection between the lamp holder and the lamp head 1, or the lamp holder and the power cord 3, or the lamp head 1 and the power cord 3.

[0029] In this embodiment, the connection between the lamp holder, lamp head 1 and power cord 3 can also be in other forms. The headlamp includes lamp head 1, lamp holder, power cord 3 and battery compartment 4. A switch is provided on the lamp head 1. The switch is used to control the power switch. The front end of the lamp head 1 passes through the lamp holder and is movably connected to the left end of the power cord 3.

[0030] As a supplement, the left end of the power cord 3 passes through the front end of the lamp head 1 but not through the rear end of the lamp head 1, which can also be understood as the left end of the power cord 3 being located inside the lamp head 1; the movable connection here means that the lamp head 1 can rotate clockwise or counterclockwise around the power cord 3, and the end of the lamp head 1 away from the power cord 3 is also movably connected to the lamp holder, so that the lamp head 1 can rotate clockwise or counterclockwise, so that the lamp head 1 can illuminate a wider range, thereby expanding the scope of use of the headlamp.

[0031] In this embodiment, as Figure 1 As shown, the lamp holder 1 is hinged to the lamp base, which is located on the right side of the lamp holder 1. The lamp base includes a first connector 5, a second connector 6, and a first gasket 7. The first connector 5 is located on the front side of the lamp holder 1 and is movably connected to the lamp holder 1. The first connector 5 is located between the lamp holder 1 and the power cord 3.

[0032] Specifically, the first connector 5 is movably connected to the power cord 3. This can also be understood as the left end of the power cord 3 passing sequentially through the first connector 5 and the lamp holder 1. Both the first connector 5 and the lamp holder 1 are fitted over the power cord 3, and both are movably connected to the power cord 3. The second connector 6 is located on the rear side of the lamp holder 1 and is movably connected to it. The front end of the first washer 7 is fixedly connected to the first connector 5, and the rear end of the first washer 7 is fixedly connected to the second connector 6. The first washer 7 is located on the right side of the lamp holder 1, and a safety distance is provided between the first washer 7 and the lamp holder 1 to accommodate the rotation of the lamp holder 1.

[0033] Understandably, in order to improve the connection strength among the first gasket 7, the first connector 5, and the second connector 6, the first gasket 7, the first connector 5, and the second connector 6 are integrally formed. This not only extends the service life of the first connector 5, the first gasket 7, and the second connector 6, but also reduces costs.

[0034] Furthermore, the first pad 7 is provided with a first curved portion, which is arranged along the length of the first pad 7. When the present invention is worn on the user's head, the first curved portion fits the front of the user's head, such as the forehead, which not only makes it more secure but also improves the user's comfort. The first pad 7 is provided with three first headband fixing buckles 7.1, which are C-shaped and open outwards from the first pad 7. Specifically, one first headband fixing buckle 7.1 is located at the front end of the first pad 7 with its opening facing forward, one first headband fixing buckle 7.1 is located at the rear end of the first pad 7 with its opening facing backwards, and one first headband fixing buckle 7.1 is located at the upper end of the first pad 7 with its opening facing upwards.

[0035] It should be noted that the C-shaped first headband fixing buckle 7.1 not only makes it convenient to install the headband on this utility model, allowing the headband to be either passed through the first headband fixing buckle 7.1 or inserted into the first headband fixing buckle 7.1 through its opening, but also makes it convenient to remove the headband from this utility model, facilitating headband replacement and saving costs.

[0036] In this embodiment, as Figure 1 and Figure 3 As shown, the right end of the power cord 3 is fixedly connected to the battery compartment 4. The battery compartment 4 has four third grooves 4.1, all located at the right end of the battery compartment 4. The four third grooves 4.1 are connected end to end to form a rectangular groove. The battery compartment 4 also has two connecting rods 4.3, both located at the lower end of the battery compartment 4, and the two connecting rods 4.3 are distributed front and back. There is a gap between the two connecting rods 4.3 and the battery compartment 4 to facilitate connection. The two connecting rods 4.3 are integrally formed with the battery compartment 4. The battery compartment 4 is connected to a cover 8, which is located on the right side of the battery compartment 4. This improves the convenience of closing the cover 8, allowing it to be opened and closed even when worn on the operator's head.

[0037] Specifically, such as Figure 1 and Figure 4As shown, the cover 8 is movably connected to the battery compartment 4. The cover 8 has two third connectors 8.3, both located at the lower end of the cover 8, and arranged in a front-to-back pattern. The third connectors 8.3 are hook-shaped, with their openings facing away from the lamp holder. The two third connectors 8.3 are integrally formed with the cover 8 and are connected to two connecting rods 4.3 respectively. In use, the third connectors 8.3 can hook onto the connecting rods 4.3, thus achieving the movable connection between the cover 8 and the battery compartment 4. The hook-shaped third connectors 8.3 facilitate connection with the connecting rods 4.3. The battery compartment 4 has a first protrusion 4.2 located at its upper end. The cover 8 has four second protrusions 8.1, all located on the left side of the cover 8, each corresponding to one of the four third grooves 4.1. The cover 8 is provided with a connecting buckle 8.2, which is located at the upper end of the cover 8. When the connecting buckle 8.2 is engaged with the first protrusion 4.2, the cover 8 is fully connected to the battery compartment 4. At this time, the cover 8 provides waterproof and dustproof protection for the battery compartment 4.

[0038] Furthermore, such as Figure 1 As shown, the battery compartment 4 is connected to a second gasket 9, which is located on the left side of the battery compartment 4. The second gasket 9 has a second curved portion, which is arranged along the length of the second gasket 9. When this invention is worn on the user's head, the second curved portion fits against the back of the user's head, which not only makes it more secure but also improves the user's comfort. The second gasket 9 is movably connected to the battery compartment 4 by bolts, and a gap is provided between the second gasket 9 and the battery compartment 4. The second gasket 9 is located between the first gasket 7 and the battery compartment 4, and the second gasket 9 is arranged opposite to the first gasket 7.

[0039] Furthermore, the second gasket 9 is also provided with three second headband fixing buckles 9.1, which are respectively opposite to the three first headband fixing buckles 7.1. The second headband fixing buckles 9.1 are C-shaped and open outwards from the second gasket 9.

[0040] Understandably, when installing the headband, it can be either passed through the second headband fixing buckle 9.1 or inserted into the second headband fixing buckle 9.1 through its opening. This also facilitates the removal and replacement of the headband, saving costs. Specifically, one second headband fixing buckle 9.1 is located at the front end of the second pad 9 with its opening facing forward, one second headband fixing buckle 9.1 is located at the rear end of the second pad 9 with its opening facing backward, and another second headband fixing buckle 9.1 is located at the upper end of the second pad 9 with its opening facing upward. The second pad 9 is provided with an inner liner (not shown in the attached drawings), located on the left side of the second pad 9. The inner liner is made of soft materials such as sponge or silicone, which not only further increases the comfort of this invention but also provides cushioning when the user's head is impacted, thus offering some protection to the head.

[0041] The headlamp in this application is worn as follows: When in use, the lamp head 1 and the battery compartment 4 are connected by a headband; specifically, the user first places the first pad 7 and the second pad 9 on the front and back of the head respectively, then the first headband connects to the first headband fixing buckle 7.1 at the front of the first pad 7 and the second headband fixing buckle 9.1 at the front of the second pad 9, the second headband connects to the first headband fixing buckle 7.1 at the upper end of the first pad 7 and the second headband fixing buckle 9.1 at the upper end of the second pad 9, and the third headband connects to the first headband fixing buckle 7.1 at the rear end of the first pad 7 and the second headband fixing buckle 9.1 at the rear end of the second pad 9; thus, the first pad 7 and the second pad 9 are stably installed on the user's head.

[0042] It should be noted that the first pad 7 and the second pad 9 are respectively provided with a first curved portion and a second curved portion, which can better fit the user's head contour when worn, further improving the stability of the headlamp. Of course, considering that different users' head shapes may vary slightly, the first pad 7 and the second pad 9 can be designed with a certain degree of elasticity to ensure that the user can control the deformation of the first pad 7 and the second pad 9 by adjusting the tightness of the headband; the material of the first pad 7 and the second pad 9 is preferably elastic plastic. Furthermore, pads that can increase comfort and anti-slip properties can be laid on the areas of the first pad 7 and the second pad 9 that are in contact with the head, and the materials of the pads include, but are not limited to, silicone, rubber, etc.

[0043] In this embodiment, as Figure 1 As shown in this embodiment, heat dissipation ribs 2 are provided at the front end, rear end, upper end, lower end and right end of the lamp head 1. The heat dissipation ribs 2 can further enhance the heat dissipation of the lamp head and strengthen the heat dissipation effect of the lamp head. The heat dissipation ribs 2 at the upper end and lower end of the lamp head are close to the heat dissipation rib 2 at the right end of the lamp head, and the heat dissipation ribs 2 at the upper end and lower end are connected to the heat dissipation rib 2 at the right end.

[0044] Furthermore, the front side of the first connector 5 is provided with two first grooves 5.1, which not only saves material while ensuring the strength of the first connector 5, but also reduces the deformation of the first connector 5, making the first connector 5 more aesthetically pleasing. The rear side of the second connector 6 is provided with two second grooves 6.1, which not only saves material while ensuring the strength of the second connector 6, but also reduces the deformation of the second connector 6, making the second connector 6 more aesthetically pleasing.

[0045] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
