Detailed Implementation
[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0020] like Figures 1-6 As shown, this embodiment of the utility model provides a multi-functional headlamp, including an expansion box 100 and at least two headlamp units 200.
[0021] The expansion box 100 contains a first battery 110 and a first control board 120. The top of the expansion box 100 has at least two headlamp mounting positions 130, and each headlamp mounting position 130 is provided with a first conductive element. The first battery 110 and the first conductive element are electrically connected to the first control board 120 respectively.
[0022] Each headlamp unit 200 can be detachably installed on the head-mounted device or detachably installed in each headlamp fixing position 130. Each headlamp unit 200 includes a housing 210, a second battery 220 and a second control board 230 disposed in the housing 210, a second conductive element disposed at the bottom of the housing 210, and a light-emitting device 250 disposed at the top of the housing 210. The second battery 220, the second conductive element and the light-emitting device 250 are electrically connected to the second control board 230. When the headlamp unit 200 is installed on the headlamp fixing position 130, the first conductive element and the second conductive element are connected.
[0023] Figure 1 The expansion box 100 shown has two headlight units 200 installed on it. It is understood that the number of headlight units 200 is not limited to two, but can also be more than two.
[0024] This application allows each headlamp unit 200 to be detached from the expansion box 100 and installed on a head-mounted device for use as a headlamp. Alternatively, each headlamp unit 200 can be installed on a headlamp mounting position 130 on the expansion box 100, enabling multi-functional applications such as ambient lighting and camping lights. The expansion box 100 has a large-capacity first battery 110 and a discharge function. When the headlamp units 200 are installed on the expansion box 100, the second battery 220 inside each headlamp unit 200 can be charged, solving the problem of real-time and multiple charging outdoors. Furthermore, by using one expansion box 100 with at least two headlamp units 200, when one headlamp unit 200 is in use, the remaining headlamp units 200 can be charged on the expansion box 100, solving the problem of short battery life.
[0025] In some embodiments, refer to Figure 2 and Figure 6 The first conductive element includes a positive electrode probe 141 and a negative electrode probe 142, and the second conductive element includes a positive electrode contact 241 and a negative electrode contact 242 corresponding to the positive electrode probe 141 and the negative electrode probe 142, respectively.
[0026] When the headlamp unit 200 is installed on the headlamp mounting position 130 on the top of the expansion box 100, the positive contact 241 on the headlamp unit 200 makes conductive contact with the positive probe 141 on the headlamp mounting position 130, and the negative contact 242 on the headlamp unit 200 makes conductive contact with the negative probe 142 on the headlamp mounting position 130, forming a charging circuit, so that the first battery 110 in the expansion box 100 charges the second battery 220 in the headlamp unit 200.
[0027] It is understood that in other embodiments, the first conductive element and the second conductive element may be electrically connected in other ways, such as a male and female plug.
[0028] This embodiment can monitor the voltage of the second battery 220 in each headlamp unit 200 in real time. When the voltage is lower than 4.2V, the first battery 110 in the expansion box 100 is controlled to charge the second battery 220 in the headlamp unit 200. When the voltage of the headlamp unit 200 is detected to be greater than 4.2V, charging is stopped. Both the expansion box 100 and each headlamp unit 200 display real-time power and charging / discharging status.
[0029] In some embodiments, refer to Figure 2 and Figure 4 An external control switch 150 is provided on the expansion box 100. The first control switch 150 is electrically connected to the first control board 120 and is used to control the light-emitting devices 250 of all headlamp units 200 installed on each headlamp fixing position 130. An external control switch 260 is provided on the outer shell 210 of the headlamp unit 200 and is electrically connected to the second control board 230 and is used to control the light-emitting devices 250 of each headlamp unit 200.
[0030] When each headlamp unit 200 is installed in the headlamp mounting position 130 on the expansion box 100, all headlamp units 200 can be controlled simultaneously by the first control switch 150 outside the expansion box 100. At this time, it is not necessary to control each headlamp unit 200 individually. When the headlamp unit 200 is used alone, it can be controlled individually by the second control switch 260 outside it.
[0031] The light-emitting device 250 in this embodiment includes LED high beam and LED low beam. When in use, different modes (such as high beam, low beam, high brightness, low brightness, red light) can be switched by pressing the first control switch 150 or the second control switch 260 multiple times to meet various usage scenarios such as long-range projection, floodlighting, and warning.
[0032] In some embodiments, the first control board 120 and the second control board 230 are connected wirelessly, for example via Bluetooth. This enables wireless communication between the first control board 120 and the second control board 230, thereby allowing the first control switch 150 to control each headlamp unit 200 mounted on the expansion box 100.
[0033] In some embodiments, refer to Figure 2 and Figure 6The headlamp mounting position 130 is equipped with a first signal transmission component electrically connected to the first control board 120. The first signal transmission component specifically includes a signal transmission probe 160. The bottom of the housing 210 of the headlamp unit 200 is equipped with a second signal transmission component electrically connected to the second control board 230. The second signal transmission component specifically includes a signal transmission contact 270. When the headlamp unit 200 is installed on the headlamp mounting position 130, the first signal transmission component and the second signal transmission component are connected. In this way, communication between the first control board 120 and the second control board 230 can be realized through a wired connection, thereby enabling the first control switch 150 to control each headlamp unit 200 installed on the expansion box 100.
[0034] In some embodiments, refer to Figure 2 The expansion box 100 is externally provided with a first charging interface 170 that is electrically connected to the first control board 120, so that the first battery 110 inside the expansion box 100 can be charged through the first charging interface 170. (Refer to...) Figure 6 Each headlamp unit 200 has a second charging interface 280 on its outer shell 210 that is electrically connected to the second control board 230. In this way, the second battery 220 inside the headlamp unit 200 can be charged not only through the first battery 110 inside the expansion box 100, but also through its external second charging interface 280.
[0035] In some embodiments, refer to Figure 2 and Figure 4 The top of the expansion box 100 is provided with positioning grooves 131 corresponding to each headlamp fixing position 130. Both ends of the positioning groove 131 are provided with buckles 132. Both ends of the outer shell 210 of the headlamp unit 200 are provided with fasteners 211. When the headlamp unit 200 is installed on the headlamp fixing position 130, the lower part of the headlamp unit 200 is positioned in the positioning groove 131, and the buckles 132 at both ends of the positioning groove 131 are respectively engaged with the fasteners 211 at the corresponding ends of the headlamp unit 200.
[0036] In some embodiments, the top of the expansion box 100 is provided with a positioning groove 131 corresponding to each headlamp fixing position 130. When the headlamp unit 200 is installed on the headlamp fixing position 130, the lower part of the headlamp unit 200 is positioned in the positioning groove 131 and is magnetically fixed to the expansion box 100.
[0037] Both of the above methods can achieve detachable installation between the expansion box 100 and the headlight unit 200. It is understood that the fixing between the expansion box 100 and the headlight unit 200 is not limited to the above-mentioned buckle 132 and magnetic connection methods.
[0038] In some embodiments, the top of the expansion box 100 is provided with an openable or closable top cover 180, and the top cover 180 has a light-transmitting window 181. In use, the top cover 180 can be closed, and the light emitted by each headlamp unit 200 shines through the light-transmitting window 181 on the top cover 180. The light-transmitting window 181 can be semi-transparent, so that the emitted light is not glaring, better meeting the lighting requirements of ambient lighting and camping lights. Of course, in use, the top cover 180 can also be opened to enhance the intensity and range of the light.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
