Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a gravity-sensing flashlight. Background Technology

[0002] A flashlight is a widely used portable lighting device, primarily used to provide a light source in dark environments. Traditional flashlights typically consist of a battery, bulb, switch, and casing. With improved living standards and more diverse application scenarios, flashlights have become increasingly versatile. In current flashlight technology, the first and second LEDs are activated independently. When using the flashlight, the user needs to either activate the first LED separately or both LEDs simultaneously. Activating all second LEDs simultaneously results in high energy consumption, which is detrimental to the flashlight's long battery life.

[0003] Therefore, it is necessary to provide a gravity-sensing flashlight to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides a gravity-sensing flashlight, which solves the problem in the prior art where flashlights illuminate either the first LED or the second LED simultaneously when turned on, which is not conducive to long battery life.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a gravity-sensing flashlight, including a body, a head connected to one end of the body, a light-emitting component located at the end of the head, and a control component located inside the head and electrically connected to the light-emitting component. The light-emitting component includes a first lamp plate located inside the head, a first lamp bead located on the first lamp plate, a second lamp plate located on one side of the first lamp plate, and a plurality of second lamp beads located on the second lamp plate and around the first lamp bead. The control component includes a control board located at one end of the head near the body and a gravity sensor located on the control board. When the gravity sensor senses that any area at the end of the head is tilted downwards, the control board controls the second lamp beads located below the first lamp beads to turn on.

[0006] In this invention, the light-emitting component further includes a reflector, which is located between the first lamp panel and the second lamp panel; The second light panel also has a first through hole at its center, and the reflector is located inside the first through hole.

[0007] In this utility model, the reflector includes a cone located on one side of the first lamp plate and a cylinder located on one side of the cone. The diameter of the cone is larger than the diameter of the cylinder. An inclined surface is provided at the end of the cylinder away from the cone. The second lamp plate is sleeved on the cylinder. The reflector is also provided with a second through hole, the opening of the second through hole near the end of the cone is smaller than the opening of the second through hole near the end of the cylinder.

[0008] In this invention, when the height of the cylinder head is lower than the height of the cylinder body and the angle between the cylinder head and the cylinder body is greater than or equal to 45°, the second lamp located below the first lamp is in the on state.

[0009] In this invention, a cap and a lens are provided at the end of the cylinder head away from the cylinder body, and the lens is detachably connected to the cylinder head through the cap.

[0010] In this utility model, a button assembly is also provided on the outer side of the cylinder head, and one end of the button assembly extends into the cylinder head; The control panel is equipped with buttons, which are positioned opposite to the button assembly.

[0011] In this invention, a battery is also installed inside the cylinder body.

[0012] In this invention, a tail cap for replacing the battery is provided at the end of the cylinder body away from the cylinder head, and the tail cap is detachably connected to the cylinder body.

[0013] In this utility model, the cylinder head is further provided with a first placement groove for placing the second lamp plate and a second placement groove located in the first placement groove for placing the first lamp plate.

[0014] In this invention, a symmetrical positioning block is provided in the first placement slot, and a positioning slot matching the positioning block is provided on the periphery of the second lamp plate, with the positioning block located in the positioning slot.

[0015] Compared with the prior art, the advantages of this utility model are as follows: When the flashlight is in use, if the flashlight head is lower than the body, the second lamp located below the first lamp turns on. If the flashlight is rotated, the second lamp that is turned on moves away from the first lamp and turns off. When the flashlight is rotated to the position below the first lamp, the second lamp turns on. Since only the second lamp below the first lamp turns on when the flashlight head is tilted, while the other second lamps remain off, the flashlight's power can be effectively saved, thereby improving the flashlight's battery life.

[0033] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0034] This utility model provides a gravity-sensing flashlight, including a body 11, a head 12 connected to one end of the body 11, a light-emitting component 13 located at the end of the head 12, and a control component located inside the head 12 and electrically connected to the light-emitting component 13. The light-emitting component 13 includes a first lamp plate 135 located inside the head 12, a first lamp bead 134 located on the first lamp plate 135, a second lamp plate 131 located on one side of the first lamp plate 135, and a plurality of second lamp beads 132 located on the second lamp plate 131 and around the first lamp bead 134. The control component includes a control board 14 located at one end of the head 12 near the body 11 and a gravity sensor located on the control board 14. When the gravity sensor senses that any area at the end of the head 12 is tilted downwards, the control board 14 controls the second lamp beads 132 located below the first lamp bead 134 to turn on. The body 11 and the head 12 are integrally formed to form a flashlight shape. The light-emitting component 13 is used to emit light, and the control component is used to control the light-emitting component 13. The flashlight head 12 is tilted downwards. The first light panel 135 is used to mount the first LED 134, and the second light panel 131 is used to mount the second LED 132. A gravity sensor detects whether the flashlight head 12 is tilted downwards. When the flashlight is in use, if the flashlight head 12 tilts downwards, the gravity sensor detects this tilt and the control component activates the second LED 132 below the first LED 134. This allows the user to activate the second LED 132 even without operating the flashlight, facilitating movement. Furthermore, because the flashlight is circular, when the flashlight head 12 tilts after rotation, the position of the activated second LED 132 changes, causing it to turn off, while the second LED 132 below the first LED 134 turns on. Since only the second LED 132 below the first LED 134 turns on when the flashlight head 12 tilts, while the other second LEDs remain off, this effectively saves energy and improves the flashlight's battery life.

[0035] In this embodiment, there are 12 second LED beads 132. When the tube head 12 is tilted, the three second LED beads 132 located below the first LED bead 134 are turned on.

[0036] Please refer to Figure 5 and Figure 6 , Figure 5 The three-dimensional light-emitting component of the gravity-sensing flashlight of this utility model. Figure 1 , Figure 6 The three-dimensional light-emitting component of the gravity-sensing flashlight of this utility model. Figure 2The light-emitting component 13 also includes a reflector 133, which is located between the first lamp plate 135 and the second lamp plate 131. The second lamp plate 131 is also provided with a first through hole at its center, and the reflector 133 is located in the first through hole. The reflector 133 is used to focus light and illuminate the object with the light emitted by the first lamp bead 134. At the same time, the second lamp plate 131 is sleeved on the reflector 133, so that the first lamp plate 135 and the second lamp plate 131 form a whole.

[0037] Please refer to Figure 7 , Figure 7 This is a perspective view of the reflector of the gravity-sensing flashlight of this utility model. The reflector 133 includes a cone 1331 located on one side of the first lamp plate 135 and a cylinder 1332 located on one side of the cone 1331. The diameter of the cone 1331 is larger than the diameter of the cylinder 1332. The end of the cylinder 1332 away from the cone 1331 is provided with an inclined surface 1333. The second lamp plate 131 is sleeved on the cylinder 1332. A second through hole 1334 is also provided inside the reflector 1333. The opening of the second through hole 1334 near the cone 1331 is smaller than the opening of the second through hole 1334 at the end near the cone 1331. The opening at one end of the cylinder 1332 allows the first lamp plate 135 to be attached to one side of the cone 1331. The first lamp bead 134 is located inside the second through hole 1334. The cylinder 1332 is used to install the second lamp plate 131, which is fitted onto the cylinder 1332. The inclined surface 1333 facilitates the insertion of the second lamp plate 131 into the cylinder 1332, making it easier to install the second lamp plate 131 onto the cylinder 1332 of the reflector 133. The second lamp plate 131 is fitted onto the reflector 133, and the reflector 133 and the first lamp plate 135 are fitted together to form a whole.

[0038] When the height of the flashlight head 12 is lower than the height of the flashlight body 11 and the angle between the flashlight head 12 and the flashlight body 11 is greater than or equal to 45°, the second lamp 132 located below the first lamp 134 is in the on state. The second lamp 132 is only in the on state when the flashlight head 12 and the flashlight body 11 are tilted to a certain position. When the flashlight head 12 and the flashlight body 11 are in a horizontal state or the flashlight head 12 is higher than the flashlight body 11, the second lamp 132 is in the off state to save power and further increase the flashlight's battery life.

[0039] The end of the tube head 12 away from the tube body 11 is also provided with a screw cap 121 and a lens 122. The lens 122 is detachably connected to the tube head 12 via the screw cap 121. The lens 122 is used to converge the light emitted by the first lamp bead 134 and the second lamp bead 132 into parallel light, thereby improving the long-range shooting capability and illumination intensity. The screw cap 121 is used to fix the lens 122 to the tube head 12, and at the same time, it is also convenient to remove the lens 122 for cleaning.

[0040] A button assembly 123 is also provided on the outside of the head 12, with one end of the button assembly 123 extending into the head 12; a button is provided on the control panel 14, with the button and the button assembly 123 positioned opposite each other. The button assembly 123 is used to control or turn on the light-emitting component 13, and can also adjust the brightness of the light-emitting component 13.

[0041] A battery 112 is also installed inside the body 11. The battery 112 is used to provide power to the light-emitting component 13 so that the flashlight can be carried out.

[0042] The end of the flashlight body 11 away from the head 12 is also provided with a tail cap 111 for replacing the battery 112. The tail cap 111 is detachably connected to the flashlight body 11 and is used to facilitate the replacement of the battery 112. When the battery 112 is out of power, the flashlight can be used again by replacing the battery 112.

[0043] Please refer to Figure 8 , Figure 8 This is a perspective view of the flashlight head of the gravity-sensing flashlight of this utility model. The flashlight head 12 is also provided with a first placement groove 124 for placing the second lamp plate 131 and a second placement groove 125 located in the first placement groove 124 for placing the first lamp plate 135. The second placement groove 125 is used to place the first lamp plate 135, and the first placement groove 124 is used to place the first lamp plate 135, so that the first lamp plate 135 and the second lamp plate 131 are spaced apart. The first placement groove 124 is provided with symmetrical positioning blocks 1241. The periphery of the second lamp plate 131 is provided with positioning grooves 1311 that match the positioning blocks 1241. The positioning blocks 1241 are located in the positioning grooves 1311. At the same time, after the second lamp plate 131 is installed in the first placement groove 124, the positioning blocks 1241 of the first placement groove 124 are engaged in the positioning grooves 1311 of the first lamp plate 135 to position the second lamp plate 131 and prevent the second lamp plate 131 from rotating in the flashlight head 12.

[0044] Working principle: When using the flashlight, the user presses the button assembly 123 to cause the light-emitting assembly 13 to emit light, and the first LED 134 is turned on. When the second LED 132 is turned on, the flashlight is tilted downwards so that the angle between the flashlight head 12 and the body 11 is greater than or equal to 45°. The second LED 132, located below the first LED 134, is turned on to increase the low beam compensation for the ground, making it easier to see the ground environment. Because the flashlight is round, the user may rotate it during use. Even after the flashlight is rotated, the position of the turned-on second LED 132 changes. Afterwards, the second LED 132 that was turned on is in the off state, and the second LED 132 that is rotated below the first LED 134 is in the on state. During use, if the user lifts the flashlight upwards so that the flashlight head 12 is horizontal with the body 11 or the flashlight head 12 is higher than the body 11, the second LED 132 will turn off, eliminating the need for the user to press the button assembly 123, making it convenient for the user. On the other hand, when the second LED 132 is turned on, only the second LED 132 located below the first LED 134 is in the on state, effectively saving the flashlight's power and increasing the flashlight's battery life.

[0045] This preferred embodiment of the gravity-sensing flashlight turns on the second LED located below the first LED when the flashlight head is lower than the body of the flashlight. When the flashlight is rotated, the second LED that is turned on moves away from the first LED and turns off. When the flashlight is rotated to the position below the first LED, the second LED turns on. Since only the second LED below the first LED is turned on when the flashlight head is tilted, while the other second LEDs remain off, the flashlight's power is effectively saved, thereby improving its battery life.

[0046] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
