Description

Technical Field

[0001] The utility model belongs to the technical field of head lamps, and in particular relates to a rechargeable head lamp. Background Art

[0002] As a lighting device worn on the head, headlamps are suitable for use in outdoor environments such as camping. However, the current power supply methods for headlamps are relatively single. One is to use dry batteries for power supply, and the other is to use rechargeable power supply. Using dry batteries for power supply is suitable for outdoor conditions without charging. When the headlamp is out of power, it can be directly replaced. However, most of the dry batteries sold on the market are non-rechargeable, so it is necessary to always have multiple dry batteries as backup. Using rechargeable power supply does not require always having multiple batteries, but it cannot be charged under the lack of charging conditions, resulting in the headlamp cannot be used normally. Therefore, these existing headlamps are difficult to be used in different usage scenarios. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a rechargeable headlamp to solve the technical problem that the existing headlamps have a relatively single power supply mode and are difficult to be used in different usage scenarios.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A rechargeable headlamp comprises: a lamp housing, a battery receiving cavity is formed on the lamp housing, a bottom surface of the battery receiving cavity is provided with recessed mounting grooves for placing dry batteries, two side walls are provided with positive and negative electrodes connected to the two ends of the dry batteries or the two ends of a lithium battery placed in the battery receiving cavity and located above the mounting groove, a light emitting module and a charging module arranged in the lamp housing and electrically connected to the electrodes, a charging port electrically connected to the charging module and extending out of the lamp housing, and further comprising: an elastically retractable on-off switch protruding between two adjacent mounting grooves, electrically connected to the charging module, capable of triggering the charging module to be turned on when the lithium battery is placed in the battery receiving cavity and abuts against the lithium battery, so that an external current can flow into the lithium battery through the charging port, the charging module and the positive and negative electrodes to charge the lithium battery;

[0008] The present application sets up two power supply modes. When there is no charging condition, the dry battery can be directly replaced for power supply. When the dry battery is placed in the installation slot, it will not touch the on-off switch, and the charging module will not charge the dry battery, ensuring the safe use of the dry battery. When there is charging condition, a lithium battery can be installed. The lithium battery has a planar structure. After placement, its side will abut against the on-off switch, triggering the charging module to turn on. At this time, insert a power supply into the charging port, and the current can flow into the lithium battery through the charging module and the positive and negative electrodes to charge the lithium battery. Therefore, the headlamp of the present application can adapt to different usage scenarios and has strong versatility.

[0009] In some embodiments, the lamp housing includes: a front cover and a rear cover detachably connected to the front cover, and a battery receiving cavity is provided on one side corresponding to the front cover and the rear cover.

[0010] In some embodiments, a socket for the charging port to extend is provided on the front cover, wherein a sealing block capable of sealing or opening the socket is provided corresponding to the socket;

[0011] The sealing block can provide waterproof protection to prevent moisture from entering the charging port in the outdoor environment and damaging the internal charging module.

[0012] In some embodiments, the on-off switch includes: a switch housing, a torsion spring disposed in the switch housing, and a first button that is retractably disposed on the switch housing, one end of the torsion spring is connected to the switch housing, and the other end is connected to the first button, and the rear side of the first button is connected to a second button disposed on the charging module;

[0013] By adding a torsion spring, the elastic force of the first button can be increased. After the lithium battery is removed, the first button can drive the second button to pop up immediately, so that the charging module is immediately cut off from the external power supply, ensuring the safety of use.

[0014] In some embodiments, it also includes a lampshade disposed on the front cover and covering the light emitting module, wherein a support block protrudes outwardly on one side of the front cover corresponding to the light emitting module to form a convex structure abutting against the rear side of the light emitting module;

[0015] By adding a support block, the rear side of the light emitting module can be tightened to prevent the light emitting module from shaking in a bumpy outdoor environment and causing the line to loosen. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] The utility model provides a rechargeable headlamp, comprising: a lamp housing 1, a battery accommodating cavity 1011 is provided on the lamp housing 1, a bottom surface of the battery accommodating cavity 1011 is spaced apart with concave mounting grooves 10111 for accommodating dry batteries 3, positive and negative electrodes 5 connected to the two ends of the dry batteries 3 or to the two ends of a lithium battery 4 placed in the battery accommodating cavity 1011 and located above the mounting grooves 10111 are respectively provided on the two side walls, a light emitting module electrically connected to the electrodes 5 and a charging module electrically connected to the electrodes 5 are arranged in the lamp housing 1, a charging port 2 electrically connected to the charging module and extending out of the lamp housing 1, and further comprising: an elastically retractable on-off switch 6 protruding between two adjacent mounting grooves 10111, electrically connected to the charging module, and capable of triggering the charging module to be turned on when the lithium battery 4 is placed in the battery accommodating cavity 1011 and abuts against it, so that an external current can flow into the lithium battery 4 through the charging port 2, the charging module and the positive and negative electrodes 5 to charge the lithium battery 4.

[0027] Specifically, there is a plane structure between two adjacent installation grooves 10111, and the on-off switch 6 is arranged on the plane structure.

[0028] Specifically, the on-off switch 6 controls the on and off of the charging module. When the on-off switch 6 is pressed downward, the charging module can be turned on. The on-off switch 6 itself has elastic force. When there is no external force to resist, the on-off switch 6 will bounce up and the charging module will stop working.

[0029] Specifically, the light emitting module and the charging module of the present application can be integrated into the same circuit board 7 , and the light emitting module and the charging module are connected in parallel and are both connected to the positive and negative electrodes 5 .

[0030] After the dry battery 3 is installed in the installation groove 10111, the dry battery 3 inputs current to the light-emitting module through the positive and negative electrodes 5 for power supply. Since the dry battery 3 is embedded in the installation groove 10111, the on-off switch 6 will not be squeezed, the charging module will not be turned on, and the dry battery 3 will not be charged, which can prevent the dry battery 3 from being mistakenly charged and causing an explosion accident.

[0031] When the lithium battery 4 is placed into the battery accommodating cavity 1011, since the lithium battery 4 is a planar structure, its side will squeeze the on-off switch 6, turning on the charging module, and the charging module starts working. At this time, if the wire of the external power supply device is inserted into the charging port 2, the current will flow into the lithium battery 4 through the charging port 2-charging module-positive and negative electrodes 5 for charging.

[0032] Specifically, the charging module itself is provided with a second button for controlling the on and off of the internal charging circuit. When the second button is pressed downward to contact the connection terminal of the internal circuit, the charging module will be turned on.

[0033] Preferably, the on-off switch 6 of the present application includes: a switch housing, a torsion spring arranged in the switch housing, and a first button movably arranged on the switch housing, one end of the torsion spring is connected to the inner wall of the switch housing, and the other end is connected to the first button, and the first button is connected to the second button immediately behind. When the lithium battery 4 is placed in the battery accommodating cavity 1011, the first button will be squeezed, and the first button will squeeze the torsion spring. At this time, the torsion spring contracts. When the lithium battery 4 is removed, the torsion spring will reset in the absence of external force, pushing the first button to move outward, and the first button can drive the second button to move outward to cut off the charging module.

[0034] Specifically, the lamp housing 1 includes: a front cover 101 and a rear cover 102 detachably connected to the front cover 101 , and a battery accommodating cavity 1011 is provided on one side corresponding to the front cover 101 and the rear cover 102 . Specifically, the front cover 101 and the rear cover 102 can be connected by a buckle.

[0035] Specifically, a socket for the charging port 2 to extend is provided on the front cover 101 or the rear cover 102 . Preferably, a sealing block 103 that can seal or open the socket is provided corresponding to the charging port 2 .

[0036] Preferably, a lampshade for housing the light emitting module is provided on the housing, and a support block protrudes outwardly on one side of the front cover 101 corresponding to the lampshade to form a convex structure, which can abut against the rear side of the light emitting module for stable installation.

[0037] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the scope of protection of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
