[0022] See also Figure 1 The embodiment of the present application provides an outdoor portable charging lamp, including a shell 1, a lamp holder 2, a lampshade 3, a light-emitting part 4, and a battery 5. The shell 1 is provided with a waterproof charging and discharging part 6; the lamp holder 2 is connected to one end of the shell 1; the lampshade 3 is connected to the other end of the shell 1; the shell 1, the lamp holder 2, and the lampshade 3 form a closed chamber; the light-emitting part 4 is arranged in the chamber; the battery 5 is built into the lamp holder 2, and the battery 5 is electrically connected to the light-emitting part 4 and the waterproof charging and discharging part 6.

[0023] In this embodiment, a completely enclosed chamber is formed by tightly connecting the outer shell 1, the lamp holder 2 and the lampshade 3. The design principle is to use physical isolation to completely isolate the key components such as the light-emitting part 4 and the battery 5 inside the lamp from the external environment (especially moisture), thereby effectively preventing moisture from invading and ensuring the dryness and safety of the inside of the lamp. The waterproof charging and discharging part 6 is arranged on the outer shell 1, so that the lamp can maintain excellent waterproof performance while being charged or discharged as a mobile power source. As a result, the outdoor portable rechargeable lamp of the present invention has an extremely high waterproof grade and can be used in various harsh outdoor environments, such as rainy days, humid environments, etc., greatly extending the service life of the product. At the same time, the design of the waterproof charging and discharging part 6 also ensures the versatility of the lamp, which can be used as a lighting tool or as a mobile power source.

[0024] Specifically, the lampshade 3 can be made of materials such as PC (polycarbonate), and the housing 1 is made of light and high-strength materials. The lampshade 3 made of PC material has excellent transparency and is relatively strong and resistant to falling compared to the lampshade 3 made of glass. This makes the lamp have good anti-fall and wear resistance and adapts to complex outdoor environments. The battery 5 uses a large-capacity lithium battery, which greatly improves the lighting endurance of the lamp and can also be used as a mobile power source, which is very suitable for outdoor adventures, camping, emergency rescue and other activities.

[0025] Optionally, the waterproof charging and discharging part 6 may include a charging / discharging port and a sealing rubber plug having the same shape as the charging / discharging port. When the lamp is in normal state, the sealing rubber plug may be inserted into the charging / discharging port and the charging / discharging port may be sealed by the sealing rubber plug to ensure the waterproof performance of the lamp. When the lamp needs to be charged or the lamp needs to be used as a mobile power source to charge other electronic devices (such as mobile phones, etc.), the sealing rubber plug on the charging / discharging port can be removed to charge or discharge through the charging / discharging port.

[0026] Although the waterproof charging and discharging part 6 can realize the charging and discharging function of the lamp and ensure the waterproof performance of the lamp, the sealing rubber plug needs to be manually pulled out / inserted before and after the charging and discharging action, which makes the charging and discharging process inconvenient; and when the lamp is charging and discharging, the sealing rubber plug pulled out from the charging / discharging port is small in size and easy to fall off, especially in complex scenes such as outdoor. Once the sealing rubber plug is lost, it is difficult to find it.

[0027] To solve the above problems, this embodiment provides another structure of the waterproof charging and discharging unit 6, such as Figure 2As shown, in this embodiment, the waterproof charging and discharging part 6 includes a charging and discharging port 61, a charging and discharging metal core 62, a slide 63, a sealing slider 64, and an elastic member 65. Among them, the charging and discharging port 61 is arranged on the housing 1, and the charging and discharging port 61 is a blind hole; the charging and discharging metal core 62 is arranged at the bottom of the charging and discharging port 61, and the charging and discharging metal core 62 is electrically connected to the battery 5; the slide 63 is arranged on the housing 1, and one end of the slide 63 is connected to the charging and discharging port 61; the sealing slider 64 is slidably matched in the slide 63, and an inclined surface is arranged at one end of the sealing slider 64 close to the charging and discharging port 61, and the inclined surface is arranged upward from the inside to the outside; the elastic member 65 is arranged in the slide 63, one end of the elastic member 65 is connected to the slide 63, and the other end of the elastic member 65 is connected to the sealing slider 64, and the sealing slider 64 closes the charging and discharging port 61 under the elastic force of the elastic member 65.

[0028] When the lamp is in a normal state, the elastic member 65 in the slide groove 63 gives the sealing slider 64 a downward elastic force, so that the sealing slider 64 slides downward under the action of the elastic force until the bottom of the sealing slider 64 is close to the inner wall of the charging and discharging port 61, and the charging and discharging port 61 is closed by the sealing slider 64 to prevent external moisture from entering the charging and discharging port 61, so as to ensure that the internal charging and discharging metal core 62 is in a dry environment. When the lamp needs to be charged / discharged, it is only necessary to insert the charging / discharging plug into the charging and discharging port 61. When the front end of the plug contacts the sealing slider 64, due to the inclined surface provided on the sealing slider 64, the horizontal squeezing force given by the plug on the sealing slider 64 will evolve into an upward squeezing force. Under the action of the upward squeezing force, the sealing slider 64 overcomes the elastic force of the elastic member 65 and slides upward, so that the originally closed charging and discharging port 61 is opened, and then the charging / discharging plug can be plugged into the internal charging and discharging metal core 62 to perform the charging / discharging action. When the lamp is finished charging / discharging, it is only necessary to unplug the plug. At this time, the sealing slider 64 will close the charging / discharging port 61 again under the elastic force of the elastic member 65 .

[0029] In summary, the waterproof charging and discharging part 6 in this embodiment is easy to use. It is not necessary to pull out / insert the sealing rubber plug before and after the charging / discharging action. It is only necessary to plug in and out the plug used for charging / discharging normally, making the charging and discharging process of the lamp convenient. And there is no need to worry about the pulled-out sealing rubber being left behind, resulting in the inability to seal the charging and discharging port 61 again, which is very suitable for use in outdoor places.

[0030] Specifically, the elastic member 65 can be a spring, a spring sheet, etc. The thickness of the sealing slider 64 is consistent with the width of the slide groove 63 , and the width of the sealing slider 64 is consistent with the width of the charge and discharge port 61 .

[0031] In order to further improve the waterproof sealing of the waterproof charging part, in one embodiment, the waterproof charging and discharging part 6 further includes a waterproof rubber strip 66, which is embedded in the charging and discharging port 61, and when the sealing slider 64 closes the charging and discharging port 61, the end (bottom) of the sealing slider 64 is pressed against the waterproof rubber strip 66. By embedding the waterproof rubber strip 66 inside the charging and discharging port 61, the sealing slider 64 can be pressed against the waterproof rubber strip 66 under the elastic force of the elastic member 65. The waterproof rubber strip 66 can be made of a material with a certain elasticity, such as rubber, to improve the sealing between the end of the sealing slider 64 and the inner wall of the charging and discharging port 61, thereby improving the waterproof sealing of the waterproof charging part.

[0032] In one embodiment, the light emitting unit 4 includes a light board 41 and a plurality of LED lamp beads 42 disposed around the light board 41. The light board 41 is fixed in the housing 1 and is electrically connected to the battery 5. Specifically, the LED lamp beads 42 may be evenly distributed around the light board 41.

[0033] like Figure 4 As shown, in one embodiment, it also includes a control unit 7, which is used to control the illumination state of the light-emitting unit 4. The control unit 7 includes a controller module 71, a photosensor 72, an infrared sensor 73, and a waterproof manual button 74. Among them, the controller module 71 is arranged in the housing 1, and the controller module 71 is arranged on the circuit between the battery 5 and the light-emitting unit 4; the photosensor 72 is built in the housing 1, and the photosensor 72 is used to automatically adjust the illumination intensity of the light-emitting unit 4 according to the external brightness; the infrared sensor 73 is arranged in the housing 1, and the infrared sensor 73 is used to receive the adjustment signal of the remote control; the waterproof manual button 74 is arranged on the housing 1, and the waterproof manual button 74 is used to manually adjust the illumination state of the light-emitting unit 4; the waterproof manual button 74, the infrared sensor 73, and the photosensor 72 are all electrically connected to the controller module 71.

[0034] Specifically, the controller module 71 is used to receive the lamp control signal transmitted by the photosensitive sensor 72, the infrared sensor 73 or the waterproof manual button 74, and control the light-emitting state (specifically including brightness, color, etc.) of the light-emitting part 4 according to the received lamp control signal.

[0035] The photosensitive sensor 72 is built into the housing 1. The portion of the housing 1 outside the photosensitive sensor 72 is made of a material with good light transmittance, such as PC material. When the lamp is turned on, the photosensitive sensor 72 can monitor the external light intensity in real time and transmit the external light intensity information back to the controller module 71. The controller module 71 adjusts the lighting intensity of the lamp according to the external light intensity (the specific adjustment method can be to control the number of light-emitting LED lamp beads 42, etc.). When the external light is good, the light intensity of the lamp is kept at a low state to reduce the power consumption of the lamp. On the contrary, when the external environment is darker, the lamp can automatically increase the light intensity to ensure that sufficient lighting can be provided for the user.

[0036] The lamp can also be controlled by remote control or by directly pressing the waterproof manual button 74. In the case of remote control, the user uses the remote control to send a control signal, and the infrared sensor 73 receives the control signal and transmits it to the controller module 71, and the controller module 71 controls the lamp according to the control signal. The manual control method of directly pressing the waterproof manual button 74 can also control the lamp through the controller module 71. By setting two manual control methods of far and near to control the operation of the lamp, the convenience of using the lamp is greatly improved to meet the control requirements in different situations. In addition, the waterproof manual button 74 can also maintain the waterproof performance of the lamp and prevent external moisture from entering the interior of the lamp through the manual button. Finally, by controlling the lighting color of the lamp, the lamp can be used as an atmosphere lamp in addition to lighting, thereby increasing the fun. Or the light color can be adjusted to yellow light, and the principle that insects hate yellow light is used to make the lamp have a certain insect repellent effect, which is particularly suitable for outdoor use.

[0037] like Figure 2 As shown, in one embodiment, the waterproof manual button 74 includes a button hole 741, a switch button 742, a waterproof elastic capsule 743, a first metal sheet 744 and a second metal sheet 745. The button hole 741 is provided on the housing 1; the switch button 742 is slidably fitted in the button hole 741; the waterproof elastic capsule 743 is covered on the inner side of the button hole 741, and the edge of the waterproof elastic capsule 743 is tightly connected to the inner wall of the housing 1; the first metal sheet 744 and the second metal sheet 745 are both electrically connected to the controller module 71 to form a control loop, the first metal sheet 744 is fixed on the housing 1, and the second metal sheet 745 is adhesively fixed to the waterproof elastic capsule 743.

[0038] By using the waterproof elastic bag 743 to seal the button hole 741, external moisture will not enter the interior of the lamp through the button hole 741. When the user presses the switch button 742, the switch button 742 slides toward the inside of the button hole 741 (such as Figure 2In the figure, it is sliding to the left) until the switch button 742 contacts the second metal sheet 745 and presses the second metal sheet 745 to contact the first metal sheet 744, thereby connecting the control circuits of the first metal sheet 744 and the second metal sheet 745, and completing the transmission of the control signal. In this process, when the switch button 742 is pressed, the waterproof elastic capsule 743 will first be stretched by the pressure given by the switch button 742, until the second metal sheet 745 adhered to the waterproof elastic capsule 743 contacts the first metal sheet 744. When the user releases the switch button 742, the rebound force of the waterproof elastic capsule 743 can separate the second metal sheet 745 from the first metal sheet 744, and the switch button 742 is moved outward (such as Figure 2 In this process, the edge of the waterproof elastic capsule 743 is always tightly connected to the inner wall of the housing 1, so that the button hole 741 is always in a closed state. Therefore, even when the user presses the switch button 742, the waterproof manual button 74 in this embodiment can still maintain good waterproof sealing performance, thereby ensuring the waterproof performance of the lamp. In addition, the waterproof elastic capsule 743 in this embodiment replaces the reset spring on the traditional button and realizes the reset function of the reset spring on the traditional button. Therefore, the waterproof elastic capsule 743 not only has a waterproof sealing function, but also can replace the reset spring on the traditional button to automatically reset the switch button 742 and the second metal sheet 745.

[0039] like Figure 1 and Figure 4 As shown, in one embodiment, a photovoltaic panel 8 is further included, which is embedded in the end of the lamp head 2 and electrically connected to the battery 5. By providing the photovoltaic panel 8 and combining it with the intelligent charging management system provided inside the lamp, the lamp can use an external light source to supplement its own power. Even if the lamp is in a weak light state, it can still be charged, thereby improving the self-sufficiency of the lamp.

[0040] Optionally, a rotatable hook 21 is also provided on the lamp head 2, and the lamp can be safely and stably hung in a fixed position through the hook 21 to facilitate the lighting use of the lamp. When the lamp is charged by the photovoltaic panel 8, the hook 21 can be used to hang the lamp in a well-lit area for charging, making it convenient to fix the lamp.

[0041] like Figure 7 As shown, in one embodiment, it also includes a closed heat dissipation ring 9, which is made of a metal material with excellent thermal conductivity (specifically, it can be made of metal copper and other materials). The closed heat dissipation ring 9 is arranged on the outer shell 1 and replaces this part of the outer shell 1. The upper and lower ends of the closed heat dissipation ring 9 are tightly matched with the outer shell 1; a plurality of longitudinal heat dissipation grooves 91 are arranged on the inner and outer beam sides of the closed heat dissipation ring 9, and the longitudinal heat dissipation grooves 91 are evenly arranged at equal intervals, and the longitudinal heat dissipation grooves 91 do not penetrate the closed heat dissipation ring 9.

[0042] The longitudinal heat dissipation grooves 91 on the closed heat dissipation ring 9 can greatly increase the heat conduction area of ​​the closed heat dissipation ring 9, which helps the heat inside the lamp to be conducted outward through the closed heat dissipation ring 9. By setting the closed heat dissipation ring 9, the excellent thermal conductivity of the closed heat dissipation ring 9 itself and the longitudinal heat dissipation grooves 91 opened inside and outside the closed heat dissipation ring 9 are utilized to make the lamp have good heat dissipation performance, and avoid the lamp from being damaged due to excessive internal temperature caused by long-term operation. In addition, the closed heat dissipation ring 9 can maintain the sealing performance of the lamp, solve the problem that the heat dissipation holes of traditional lamps are easy to get water in, and achieve a balance between heat dissipation performance and waterproof performance.

[0043] In one embodiment, an annular groove 63 is provided on the housing 1, and the closed heat dissipation ring 9 is slidably fitted in the annular groove 63 (the upper and lower sides of the closed heat dissipation ring 9 are partially connected to the housing 1 by means of Figure 3 The annular groove 63 is fixedly connected to the connecting rod in the housing 1, and a sealing ring is also provided at the bottom of the annular groove 63. By providing the annular groove 63 and the sealing ring on the housing 1, the sealing ring is used to improve the sealing performance between the housing 1 and the closed heat dissipation ring 9, thereby improving the sealing performance of the lamp.

[0044] When users use it outdoors, in addition to the need for near-range lighting, they also need to illuminate the distant areas. For example, when walking outdoors at night, they need lamps to illuminate the distant roads. Figure 4-6 As shown, in one embodiment, it also includes a light switching unit, which includes an inner light focusing tube 101, an outer light focusing tube 102, a screw 103, a gear 104, and a nut 105. Among them, the inner light focusing tube 101 is covered on the light-emitting surface of the light-emitting unit 4; the outer light focusing tube 102 is slidably matched with the outside of the inner light focusing tube 101, and the outer light focusing tube 102 is a straight tube; the two ends of the screw 103 are rotatably connected to the housing 1, and the sliding direction of the screw 103 is the same as the sliding direction of the outer light focusing tube 102; the gear 104 is fixed on the screw 103, and the gear 104 is meshed with the longitudinal heat dissipation groove 91; the nut 105 is matched with the screw 103, and the nut 105 is connected to the outer light focusing tube 102.

[0045] When the lamp is used for near-range lighting, that is, in normal lighting state, the outer focusing tube 102 overlaps with the inner focusing tube 101 (the trumpet-shaped conical tube) (such as Figure 5 As shown in the figure, the light emitted by the light emitting part 4 is diffused downward toward the lampshade 3 under the action of the inner focusing tube 101, forming a near range illumination. When it is necessary to illuminate the far distance, it is only necessary to twist the closed heat dissipation ring 9, and use the longitudinal heat dissipation groove 91 inside the closed heat dissipation ring 9 to drive the gear 104 to rotate, thereby driving the screw rod 103 to rotate, so that the nut 105 on the screw rod 103 and the outer focusing tube 102 slide downward and extend (as shown in the figure). Figure 6As shown in FIG. 1 ), the light emitted by the light emitting part 4 is gathered by the extended outer focusing tube 102, so that the light is gathered in the middle to illuminate the distant area, realizing a lighting function similar to a flashlight. When it is necessary to illuminate the nearby area, the closed heat dissipation ring 9 can be switched by simply twisting it in the opposite direction, so that the lamp can not only realize the illumination in the nearby area like a bulb, but also realize the illumination in the distant area like a flashlight.

[0046] Furthermore, during the process of twisting the closed heat dissipation ring 9, the outer longitudinal heat dissipation grooves 91 can also increase the friction between the user and the closed heat dissipation ring 9, which is conducive to the user to easily switch the lighting mode of the lamp.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
