Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an emergency light. Background Technology

[0002] Traditional emergency lights have a battery compartment inside the lamp holder for storing batteries. The lamp holder has a battery cover. Opening the battery cover allows the battery to be placed in the battery compartment or removed from the battery compartment. In this way, the battery can be used as an emergency light source in the event of a power outage.

[0003] However, with traditional emergency lights, changing the battery requires prying the battery cover off the lamp holder. This can be difficult because it's hard to find the latch or the latch is too small to pry open. This means the emergency light needs to be removed from the mounting end to replace the battery. Frequent removal and installation of the emergency light can also lead to poor contact, causing the LEDs to lose light and reducing the lifespan of the emergency light.

[0004] Therefore, there is an urgent need for a product that can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem of poor user experience when changing batteries in existing emergency lights.

[0006] To solve the above-mentioned technical problems, this utility model provides an emergency light, which adopts the following technical solution: The emergency light includes a lamp cup and a rotating outer shell fitted onto the lamp cup and rotatable relative to the lamp cup. The peripheral wall of the lamp cup is provided with at least one first placement opening, and the peripheral wall of the rotating outer shell is provided with at least one second placement opening. A battery compartment is provided inside the lamp cup and located at the first placement opening. The rotating outer shell rotates until the second placement opening overlaps with the first placement opening, so that the battery compartment is in the open state; The rotating housing rotates until its peripheral wall overlaps with the first placement opening, thereby closing the battery compartment.

[0007] Optionally, the first placement port has at least two, and the number of the second placement ports is the same as the number of the first placement ports; The rotating outer shell is rotated until each of the second placement ports overlaps with the corresponding first placement port, so that each of the battery compartments is in the open state; The rotating housing rotates until the peripheral wall of each rotating housing overlaps with each of the first placement openings, so that each of the battery compartments is in a closed state.

[0008] Optionally, the first placement port has at least two, and the second placement port has one; The rotating outer shell rotates until the second placement port overlaps with any of the first placement ports, so that the battery compartment corresponding to the first placement port is in the open state; The rotating housing rotates until its peripheral wall overlaps with each of the first placement openings, so that each of the battery compartments is in a closed state.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides an emergency light 100, such as Figure 1 As shown, the emergency light 100 includes a lamp holder 10 and a rotating outer shell 20. The rotating outer shell 20 can be fitted onto the lamp holder 10 and can rotate relative to the lamp holder 10. The shape of the rotating outer shell 20 can be basically the same as that of the lamp holder 10. Both can be frustum-shaped, cylindrical, etc., or based on frustum-shaped, cylindrical, etc., with the peripheral walls rounded. That is to say, the cross-section of the lamp holder 10 and the rotating outer shell 20 can be circular.

[0024] The lamp holder 10 may have at least one first placement opening 11 on its peripheral wall, and the rotating housing 20 may have at least one second placement opening 21 on its peripheral wall. A battery compartment 30 may be provided inside the lamp holder 10 and located at the first placement opening 11. The battery compartment 30 can accommodate cylindrical batteries 90, such as 18650 lithium batteries, AA dry cell batteries, etc. Each battery compartment 30 is connected to the corresponding first placement opening 11, allowing the battery 90 to be removed from the battery compartment 30 through the first placement opening 11 and to be placed into the battery compartment 30 through the first placement opening 11.

[0025] Understandably, the operating principle of replacing the battery 90 of the emergency light 100 is roughly as follows: Combined with appendix Figure 1 As shown in Figure (a), when the emergency light 100 needs to replace the battery 90, the rotating housing 20 can be rotated until the second placement port 21 overlaps with the first placement port 11, and the second placement port 21 is connected to the first placement port 11. That is, the second placement port 21 is connected to the battery compartment 30 through the first placement port 11, so that the battery compartment 30 is in the open state. At this time, the battery can be taken out from the battery compartment 30 through the first placement port 11 and the second placement port 21, or the battery 90 can be put into the battery compartment 30 through the second placement port 21 and the first placement port 11.

[0026] Combined with appendix Figure 1 As shown in Figure (b), after the emergency light 100 has replaced the battery 90, the rotating housing 20 is rotated so that the peripheral wall of the rotating housing 20 overlaps with the first placement port 11, that is, the second placement port 21 overlaps with the peripheral wall of the lamp cup 10. At this time, the peripheral wall of the rotating housing 20 covers the first placement port 11 so that the battery compartment 30 is in the closed state.

[0027] In summary, compared with existing technologies, the emergency light 100 has at least the following beneficial effects: When the emergency light 100 needs battery 90 replacement, the rotating housing 20 is rotated until its second placement opening 21 overlaps with the first placement opening 11 of the lamp holder 10, thus opening the battery compartment 30. At this point, the battery 90 can be removed from and / or placed back into the battery compartment 30. After replacing the battery 90, the rotating housing 20 is rotated until its peripheral wall overlaps with the first placement opening 11, thus closing the battery compartment 30. In short, the emergency light 100 allows the battery compartment 30 to be switched between open and closed states simply by rotating the rotating housing 20, facilitating battery 90 replacement without removing the emergency light 100 from its mounting end. Opening the battery compartment 30 is also straightforward, providing users with a superior user experience when replacing the battery 90.

[0028] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0029] In some embodiments, as one way of setting up the first placement port 11 and the second placement port 21, such as Figure 1 and Figure 2 As shown, the first placement port 11 can have at least two, and the number of second placement ports 21 can be the same as the number of first placement ports 11. Based on this, the operating principle of the emergency light 100 for replacing the battery 90 is roughly as follows: When the emergency light 100 needs to replace the battery 90, rotate the rotating housing 20 until each of the second placement ports 21 overlaps with the corresponding first placement port 11, that is, each of the second placement ports 21 is connected to the corresponding battery compartment 30 through the corresponding first placement port 11, so that each battery compartment 30 is in the open state, and the battery 90 can be replaced at this time.

[0030] After the emergency light 100 has replaced the battery 90, rotate the rotating housing 20 until each of the second placement ports 21 overlaps with the peripheral wall of the lamp cup 10. At this time, the peripheral wall of the rotating housing 20 covers each of the first placement ports 11 so that each battery compartment 30 is in the closed state.

[0031] In some embodiments, as another arrangement of the first placement port 11 and the second placement port 21, the first placement port 11 may have at least two locations, and the second placement port 21 may have only one location. Based on this, the operating principle of the emergency light 100 for replacing the battery 90 is roughly as follows: When the emergency light 100 needs to replace the battery 90, rotate the housing 20 until the second placement port 21 overlaps with any of the first placement ports 11. That is, the second placement port 21 is connected to the corresponding battery compartment 30 through the overlapping first placement port 11, so that the battery compartment 30 is in the open state, and the battery 90 can be replaced at this time.

[0032] After the emergency light 100 has replaced the battery 90, rotate the rotating housing 20 until the peripheral wall of the rotating housing 20 overlaps with each of the first placement openings 11. At this time, the peripheral wall of the rotating housing 20 covers each of the first placement openings 11 so that each battery compartment 30 is in the closed state.

[0033] Of course, the specific arrangement of the first placement port 11 and the second placement port 21 is not limited to the two mentioned above. As long as the second placement port 21 overlaps with the first placement port 11 of the lamp cup 10 by rotating the rotating housing 20 so that the battery compartment 30 is in the open state; and the second placement port 21 is offset from the first placement port 11 by rotating the rotating housing 20 so that the two are not connected so that the battery compartment 30 is in the closed state, it is a solution that this application seeks to protect.

[0034] In some embodiments, such as Figure 2As shown, each first placement port 11 can be evenly spaced along the periphery of the lamp cup 10. Based on the former arrangement of the first placement port 11 and the second placement port 21, each second placement port 21 can be arranged corresponding to the arrangement of each first placement port 11.

[0035] Of course, the spacing between each of the first placement ports 11 can also be different.

[0036] In some embodiments, such as Figures 2 to 4 As shown, the head of the lamp cup 10 may be provided with a lamp holder fixing part 12, an annular spring piece 40, and a first positioning bone 13. The lamp holder fixing part 12 may be inserted through the head of the rotating housing 20, that is, the lamp cup 10 is located inside the rotating housing 20, and the lamp holder fixing part 12 extends out of the rotating housing 20. The annular spring piece 40 may be arranged around the lamp holder fixing part 12, and the first positioning bone 13 may be arranged along the circumference of the lamp holder fixing part 12. The first fixing bone 13 may also have the function of fixing the annular spring piece 40.

[0037] The annular spring 40 may have a limiting portion 41, which may be formed by a portion of the annular spring 40 protruding in the direction of extending from the lamp holder fixing portion 12. The limiting portion 41 and the first positioning bone 13 may be arranged adjacent to each other, and a second positioning bone 22 may be provided inside the rotating housing 20 and located on the head of the rotating housing 20.

[0038] Understandably, the positioning self-locking and unlocking principle of the rotating outer shell 20 is roughly as follows: When the rotating housing 20 rotates to the point where the second positioning bone 22 compresses and deforms the limiting part 41 so that the second positioning bone 22 is placed between the limiting part 41 and the first positioning bone 13, the limiting part 41 returns to its original shape. The limiting part 41 and the first positioning bone 13 cooperate to restrict the rotation of the rotating housing 20 relative to the lamp cup 10, thereby achieving a self-locking function and effectively preventing the rotating housing 20 from becoming loose.

[0039] When the rotating housing 20 rotates to the point where the second positioning bone 22 compresses and deforms the limiting part 41, causing the second positioning bone 22 to disengage from the limiting part 41 and the first positioning bone 13, the rotating housing 20 can rotate relative to the lamp cup 10 to achieve the unlocking function.

[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, the head of the lamp cup 10 may also be provided with a limiting bone 14. The limiting bone 14 and the first positioning bone 13 may be arranged along the circumference of the lamp head fixing part 12, and the limiting part 41 may be located between the limiting bone 14 and the first positioning bone 13. The second positioning bone 22 may move between the first positioning bone 13 and the limiting bone 14, so that when the second positioning bone 22 moves to abut against the limiting bone 14, the second placement port 21 overlaps with the first placement port 11.

[0041] Specifically in this embodiment, such as Figure 4As shown, two second positioning bones 22 may be provided, and the two second positioning bones 22 may be evenly spaced along the circumference of the head of the rotating shell 20 to limit the rotation stroke of the rotating shell 20.

[0042] In some embodiments, such as Figure 3 As shown, the head of the lamp cup 10 may also be provided with at least one fixing bone 15. The fixing bone 15, the limiting bone 14, and the first positioning bone 13 may all be arranged along the circumference of the lamp head fixing part 12. The fixing bone 15 may cooperate with the limiting bone 14 to fix the annular spring 40; or, the fixing bone 15 may cooperate with the first positioning bone 13 to fix the annular spring 40; or, the fixing bone 15 may cooperate with the limiting bone 14 and the first positioning bone 13 to fix the annular spring 40 simultaneously; of course, the limiting bone 14 and the first positioning bone 13 may also cooperate to fix the annular spring 40.

[0043] Specifically in this embodiment, such as Figure 3 As shown, the head of the lamp cup 10 is provided with two fixing bones 15. The limiting bone 14, the first positioning bone 13 and the two fixing bones 15 are all evenly spaced along the circumference of the lamp head fixing part 12 to improve the stability of the annular spring 40 installed on the tail of the lamp cup 10.

[0044] In some embodiments, such as Figure 2 As shown, the lamp cup 10 may be provided with a light source board 50 and a driver board 60. The light source board 50 may be located near the tail of the lamp cup 10, and the driver board 60 may be located on the side of the light source board 50 facing the head of the lamp cup 10. Both the battery compartment 30 and the driver board 60 may be electrically connected to the light source board 50.

[0045] In some embodiments, such as Figure 2 As shown, the tail of the lamp cup 10 can be covered with a lamp shade 70 to cover the light source plate 50. When the light source plate 50 emits light, the light can be emitted through the lamp shade 70.

[0046] In some embodiments, such as Figure 2 As shown, the lamp holder fixing part 12 can be fitted with a lamp holder structure 80, and the emergency light 100 can be electrically connected to the installation end through the lamp holder structure 80.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
