Description

Technical Field

[0001] This invention relates to the field of energy-saving flashlight technology, specifically an energy-saving police flashlight that can be detachably equipped with a strobe projection device. Background Technology

[0002] As a core piece of equipment carried 24 hours a day by special police, patrol officers, and emergency response personnel, the reliability of police flashlights directly affects the success or failure of missions and the safety of personnel. Traditional products generally adopt a minimalist architecture with a single LED light source and a reflector bowl. Although this can meet the brightness requirements for daily patrols, it has a fatal flaw of "single point failure": once the chip goes out due to overcurrent breakdown, phosphor thermal quenching, or cracked solder pads, the user can only disassemble the lamp head, replace the spare LED, or replace the entire flashlight in a dark environment.

[0003] In civilian scenarios, users can operate with ease, but in extreme missions such as encirclement, search and rescue, and counter-terrorism in subway tunnels, every second of pause may allow the target to escape, hostages to be injured, or teammates to be put on the defensive. Moreover, the scene often lacks backup light sources, dust-free conditions, and space for hands to operate, leading to a chain of risks of "the mission stops when the lights go out". Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving police flashlight that can be detachably equipped with a strobe projection device, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An energy-saving police flashlight with a detachable strobe projection device includes: The flashlight body contains an LED light-emitting module and a reflector, and the LED light-emitting module can extend into the reflector. The lampshade is detachably mounted on one end of the flashlight body; The telescopic rod is provided in two sets and slidably installed inside the flashlight body. Each set of telescopic rods is connected to one end of the LED light-emitting module. A side plate is fixedly installed inside the flashlight body. A guide groove is provided on the side plate, and the telescopic rod can roll along the guide groove. The drive structure is slidably mounted on the flashlight body and connected to the telescopic rod. The drive structure cooperates with the telescopic rod to allow the two sets of LED light-emitting modules to alternately enter the interior of the reflector.

[0006] As described above, the energy-saving police flashlight with detachable strobe projection device has a guide block at the end of each of the two sets of telescopic rods away from the LED light-emitting module. The guide block can slide in the guide installed in the flashlight body. When the telescopic rod is activated, the guide block cooperates with the guide member to enable the telescopic rod to move in the direction perpendicular to the length of the flashlight body.

[0007] The energy-saving police flashlight with detachable strobe projection device as described above: the telescopic rod includes a guide sleeve fixedly connected to the guide block and a telescopic shaft slidably installed in the guide sleeve, the end of the telescopic shaft away from the guide block being electrically connected to the LED light-emitting module; The guide sleeve has a through groove along its length, and a first convex shaft rotatably mounted on the telescopic shaft can pass through the through groove and roll within the guide groove.

[0008] The energy-saving police flashlight with detachable strobe projection device as described above: a second cylindrical spring is sleeved on the telescopic shaft, one end of the second cylindrical spring is connected to the end of the telescopic shaft, and the other end is connected to the guide sleeve; The guide groove includes a vertical groove disposed on the side plate and a first horizontal groove and a second horizontal groove perpendicular to the vertical groove. The first horizontal groove and the second horizontal groove are collinear and connected along the length direction.

[0009] The energy-saving police flashlight with detachable strobe projection device as described above: the driving structure includes a driving component that slides through the flashlight body, one end of the driving component is provided with a pushing part, and the driving component is provided with a second tilting groove; The drive structure further includes a second cam shaft that is rotatably connected to the first cam shaft, and the second cam shaft is capable of rolling within the second inclined groove.

[0010] The energy-saving police flashlight with a detachable strobe projection device, as described above, also includes: A connector is fixedly mounted on the flashlight body, and a guide groove is provided on the connector. The strobe projection module is detachably connected to the guide groove. An elastic locking component is disposed on the connector. The elastic locking component can lock the strobe projection module to the connector and, when the elastic locking component moves in the opposite direction, can push the strobe projection module out of the connector.

[0011] The energy-saving police flashlight with detachable strobe projection device as described above: the guide groove includes a first inclined groove and an arc-shaped groove provided on the side wall of the connecting seat, and the bottom of the first inclined groove is arc-shaped; The strobe projection module is provided with a first fitting shaft and a second fitting shaft that are respectively adapted to the first inclined groove and the arc groove.

[0012] The energy-saving police flashlight with detachable strobe projection device as described above: the center of the arc-shaped groove is concentric with the bottom of the first inclined groove, and the radius of the arc-shaped groove is the same as the distance between the first fitting axis and the second fitting axis.

[0013] The energy-saving police flashlight with a detachable strobe projection device as described above: the elastic locking assembly includes: Two sets of guide members are fixedly installed on the side of the connecting seat, and one end of each guide member is provided with a stop. A locking member is slidably mounted on the guide member, the locking member having a sliding connection part that is slidably connected to the guide member, and a connecting rod is also connected to the locking member; A first cylindrical spring is connected at one end to the connecting seat, and the other end of the first cylindrical spring is connected to the locking member.

[0014] The energy-saving police flashlight with detachable strobe projection device as described above: the locking member is provided with a first inclined guide surface, a locking groove and a second inclined guide surface. When the locking member abuts against the stop part, the first inclined guide surface can abut and adapt to the second fitting shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The telescopic rods, side plates, and drive structure enable the two sets of LED light-emitting modules to switch quickly. If one set of LED light-emitting modules is damaged, the other set of LED light-emitting modules can be switched into the reflector bowl. This ensures that the use of the flashlight is not affected by the damage to the LED light-emitting modules in extreme conditions. Furthermore, the cooperation between the guide groove and the first convex shaft ensures the precise positioning of the two sets of LED light-emitting modules, which to a certain extent guarantees the subsequent flashlight illumination effect. By using the connector, strobe projection module, and elastic locking component, when the first engagement shaft is in the first inclined groove and the second engagement shaft is engaged with the elastic locking component, the first engagement shaft and the second engagement shaft can be stably locked, ensuring the connection stability between the strobe projection module and the flashlight body. This enables quick disassembly and installation of the strobe projection module to meet the extreme conditions in police use and allow the flashlight to be put into use quickly.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-10 As an embodiment of the present invention, the energy-saving police flashlight with detachable strobe projection device includes: flashlight body 1, lampshade 2, telescopic rod, side plate 20 and drive structure.

[0029] The flashlight body 1 is equipped with an LED light-emitting module 12 and a reflector bowl 3. The LED light-emitting module 12 can extend into the reflector bowl 3. It should be noted that the LED light-emitting module 12 is specifically a combination of gallium nitride-based blue LED chip and rare earth phosphor. With this combination, firstly, the gallium nitride-based blue LED chip allows electrons and holes to recombine directly in the blue light band, generating almost no infrared / heat loss, which greatly improves the quantum efficiency in electro-optic theory; secondly, the Stokes shift of the rare earth phosphor is only about 0.24 eV, which can convert blue light energy into visible white light and reduce heat loss. This greatly reduces the power consumption of the LED light-emitting module 12 during use and effectively improves the brightness. Compared with traditional sodium lamps and LED lamps, it is more energy-efficient and can increase the continuous use time of the flashlight with the same battery capacity.

[0030] The lampshade 2 is detachably mounted on one end of the flashlight body 1; A guide block 18 is provided at one end of each set of telescopic rods away from the LED light-emitting module 12. The guide block 18 can slide in the guide member 19 installed in the flashlight body 1. When the telescopic rod is activated, the guide block 18 cooperates with the guide member 19 to enable the telescopic rod to move along the length of the flashlight body 1 in a direction perpendicular to the length. Two sets of telescopic rods are provided and slidably installed inside the flashlight body 1. Each set of telescopic rods is connected to one end of an LED light-emitting module 12. The telescopic rod includes a guide sleeve 16 fixedly connected to the guide block 18 and a telescopic shaft 13 slidably installed in the guide sleeve 16. The end of the telescopic shaft 13 away from the guide block 18 is electrically connected to the LED light-emitting module 12. The guide sleeve 16 is provided with a through groove 1601 along its length direction. The first convex shaft 14, which is rotatably mounted on the telescopic shaft 13, can pass through the through groove 1601 and can roll within the guide groove.

[0031] In the initial state, one set of LED light-emitting modules 12 is inside the reflector bowl 3, while the other set is inside the flashlight body 1. At this time, the LED light-emitting modules 12 inside the reflector bowl 3 are in the working position, and can be controlled by the control switch on the flashlight body 1. When the LED light-emitting module 12 in the working position is damaged, the driving structure can drive the LED light-emitting module 12 towards the guide member 19, so that the LED light-emitting module 12 can move towards the inside of the flashlight body 1. When the LED light-emitting module 12 moves into the flashlight body 1, it will move vertically along the length of the flashlight body 1, and cause another set of LED light-emitting modules 12 to follow the movement and move towards the center of the reflector bowl 3. When the LED light-emitting module 12 moves to the end of its stroke, the other set of LED light-emitting modules 12 can be accurately inserted into the reflector bowl 3, thereby realizing the rapid switching of the two sets of LED light-emitting modules 12. This ensures that when one set of LED light-emitting modules 12 is damaged, the flashlight can still be used normally by performing the switching action, and ensures the flashlight's performance in extreme conditions.

[0032] Please see Figures 7-10 The side plate 20 is fixedly installed inside the flashlight body 1, and a guide groove is provided on the side plate 20, so that the telescopic rod can roll along the guide groove; A second cylindrical spring 17 is sleeved on the telescopic shaft 13. One end of the second cylindrical spring 17 is connected to the end of the telescopic shaft 13, and the other end is connected to the guide sleeve 16. The guide groove includes a vertical groove 2002 disposed on the side plate 20 and a first horizontal groove 2001 and a second horizontal groove 2003 perpendicular to the vertical groove 2002. The first horizontal groove 2001 and the second horizontal groove 2003 are collinear and connected along the length direction.

[0033] In this embodiment, for ease of understanding, the two LED light-emitting modules 12 are respectively labeled as LED light-emitting module 12a and LED light-emitting module 12b. In the initial state, LED light-emitting module 12a is located inside the reflector bowl 3. At this time, the first convex shaft 14 on LED light-emitting module 12a is located at the end of the vertical groove 2002 away from the first horizontal groove 2001, while the first convex shaft 14 on LED light-emitting module 12b is located at the end of the first horizontal groove 2001 away from the second horizontal groove 2003. In this state, the compression of the second cylindrical spring 17 connecting LED light-emitting module 12b is greater than the compression of the second cylindrical spring 17 connecting LED light-emitting module 12a, thereby enabling LED light-emitting module 12a and LED light-emitting module 12b to maintain a stable position.

[0034] During the switching process, the drive structure first causes the telescopic shaft 13 connected to the LED light-emitting module 12a to move towards the inside of the guide sleeve 16, further compressing the second cylindrical spring 17 connected to the LED light-emitting module 12a. Simultaneously, the first convex shaft 14 moves along the vertical groove 2002 towards the first horizontal groove 2001. When the first convex shaft 14 reaches the end of the vertical groove 2002, it will also move along the second horizontal groove 2003. At this time, both sets of guide sleeves 16 will move along the guide member 19, allowing the first convex shaft 14 connected to the LED light-emitting module 12b to move along the first horizontal groove 2001 towards the vertical groove 2002, until the middle of the LED light-emitting module 12a and the reflector bowl 3. When the LED light-emitting module 12b is misaligned and overlaps with the middle of the reflector bowl 3, the second cylindrical spring 17 connecting the LED light-emitting module 12b releases elastic potential energy to push the LED light-emitting module 12b toward the inside of the reflector bowl 3. When the first convex shaft 14 connecting the LED light-emitting module 12b moves to the end of the vertical groove 2002, the LED light-emitting module 12b is locked, so that the LED light-emitting module 12b moves into position. This achieves rapid switching between the LED light-emitting module 12a and the LED light-emitting module 12b. Through the above settings, with the cooperation of the guide groove and the first convex shaft 14, the precise positioning of the two sets of LED light-emitting modules 12 can be guaranteed, which to a certain extent ensures the subsequent flashlight illumination effect.

[0035] The drive structure is slidably mounted on the flashlight body 1 and connected to the telescopic rod. The drive structure cooperates with the telescopic rod to allow the two sets of LED light-emitting modules 12 to alternately enter the reflector bowl 3. The driving structure includes a driving member 21 that slides through the flashlight body 1, a pushing part 22 is provided at one end of the driving member 21, and a second inclined groove 2101 is provided on the driving member 21. The drive structure also includes a second cam 15 that is rotatably connected to the first cam 14 on the same axis, and the second cam 15 is capable of rolling within the second inclined groove 2101.

[0036] In this embodiment, the first convex shaft 14 connecting the two sets of LED light-emitting modules 12 each has an "L"-shaped track, and the two share a vertical groove 2002, while the second inclined groove 2101 is in an inclined state, see reference. Figure 8In the initial state, when the upper push part 22 is pushed, the second convex shaft 15 connecting the LED light-emitting module 12a can slide within the second inclined groove 2101, and the first convex shaft 14 connecting the LED light-emitting module 12a will roll in the vertical groove 2002, so that in the initial state, the second convex shaft 15 is locked at the end of the second inclined groove 2101. When the first convex shaft 14 connecting the LED light-emitting module 12a moves to the end of the vertical groove 2002 and begins to move along the second horizontal groove 2003, the corresponding second convex shaft 15 will also move along the second horizontal groove 2003. The two inclined slots 2101 move, at which time the second horizontal slot 2003 and the second horizontal slot 2003 have an angle, so that the LED light-emitting module 12a can be misaligned with the center of the reflector bowl 3. During the above process, the LED light-emitting module 12b will move towards the center of the reflector bowl 3. When the first convex shaft 14 on the LED light-emitting module 12b moves to the vertical slot 2002, the elastic potential energy is released by the second columnar spring 17, which can push the LED light-emitting module 12b towards the inside of the reflector bowl 3, thereby realizing the rapid switching of the two sets of LED light-emitting modules 12.

[0037] Based on the above settings, the two sets of LED light-emitting modules 12 can switch quickly, so that when one set of LED light-emitting modules 12 is damaged, the other set of LED light-emitting modules 12 can be switched into the reflector bowl 3. This ensures that the use of the flashlight is not affected by the damage to the LED light-emitting modules 12 under extreme conditions. Furthermore, with the cooperation of the guide groove and the first convex shaft 14, the precise positioning of the two sets of LED light-emitting modules 12 can be ensured, which to a certain extent guarantees the subsequent flashlight illumination effect.

[0038] Please see Figures 1-5 The energy-saving police flashlight with detachable strobe projection device also includes: a connector 4, a strobe projection module 9, and an elastic locking component.

[0039] The connecting seat 4 is fixedly mounted on the flashlight body 1, and the connecting seat 4 is provided with a guide groove; The guide groove includes a first inclined groove 401 and an arc-shaped groove 402 disposed on the side wall of the connecting seat 4, wherein the bottom of the first inclined groove 401 is arc-shaped. The strobe projection module 9 is provided with a first fitting shaft 10 and a second fitting shaft 11 that are respectively adapted to the first inclined groove 401 and the arc groove 402. Specifically, the center of the arc groove 402 is concentric with the bottom of the first inclined groove 401, and the radius of the arc groove 402 is the same as the distance between the first fitting shaft 10 and the second fitting shaft 11.

[0040] In this embodiment, when the strobe projection module 9 is installed onto the connector 4, the first fitting shaft 10 is first engaged into the first inclined groove 401. When the first fitting shaft 10 moves to the end of the first inclined groove 401, the strobe projection module 9 is rotated around the first fitting shaft 10 as the rotation center, so that the second fitting shaft 11 can make a circular motion around the first fitting shaft 10 as the rotation center and enter the arc groove 402. When the second fitting shaft 11 enters the arc groove 402, it can cooperate with the elastic locking component to achieve the locking effect of the second fitting shaft 11. At this time, the first fitting shaft 10 is locked by the first inclined groove 401, and the second fitting shaft 11 is locked by the elastic locking component, thus realizing a stable connection between the strobe projection module 9 and the connector 4.

[0041] Please see Figures 3-5 The strobe projection module 9 is detachably connected to the guide groove. The elastic locking component is disposed on the connecting seat 4. The elastic locking component can lock the strobe projection module 9 to the connecting seat 4, and when the elastic locking component moves in the opposite direction, it can push the strobe projection module 9 out of the connecting seat 4. The resilient locking component includes: Two sets of guide members 5 are fixedly installed on the side of the connecting seat 4, and a stop part 501 is provided at one end of the guide member 5; A locking member 7 is slidably mounted on the guide member 5. The locking member 7 is provided with a sliding connection part 701, which is slidably connected to the guide member 5. A connecting rod 8 is also connected to the locking member 7. The locking member 7 is provided with a first inclined guide surface 702, a locking groove 703, and a second inclined guide surface 704. When the locking member 7 abuts against the stop part 501, the first inclined guide surface 702 can abut and adapt to the second fitting shaft 11.

[0042] One end of the first cylindrical spring 6 is connected to the connecting seat 4, and the other end of the first cylindrical spring 6 is connected to the locking member 7.

[0043] In this embodiment, in the initial state, the first cylindrical spring 6 is in a stretched state, and the locking member 7 is in abutting against the stop portion 501. At the same time, the first inclined guide surface 702 is facing the arc groove 402. When the second fitting shaft 11 moves in a circular motion with the first fitting shaft 10, it can directly act on the first inclined guide surface 702 when entering the arc groove 402, and drive the locking member 7 to move away from the first cylindrical spring 6 along the length direction of the guide member 5. When the second fitting shaft 11 is engaged in the locking groove 703, the second fitting shaft 11 is locked. In this state, the second fitting shaft 11 abuts against the locking groove 703 and causes the second fitting shaft 11 to tend to move towards the first fitting shaft 10, thereby ensuring that the first fitting shaft 10 can be stably engaged at the bottom of the first inclined groove 401, and ensuring the stable locking of the first fitting shaft 10 and the second fitting shaft 11.

[0044] Furthermore, during the disassembly of the strobe projection module 9, pulling the connecting rod 8 allows the locking member 7 to move away from the first cylindrical spring 6, while the second inclined guide surface 704 moves toward the second mating shaft 11. When the two come into contact, the second inclined guide surface 704 can push the second mating shaft 11 upward, thus achieving a more convenient disassembly effect.

[0045] Based on the above settings, when the first fitting shaft 10 is in the first inclined groove 401 and the second fitting shaft 11 is engaged with the elastic locking component, the first fitting shaft 10 and the second fitting shaft 11 can be stably locked, ensuring the connection stability between the strobe projection module 9 and the flashlight body 1, thereby realizing the quick disassembly and quick assembly of the strobe projection module 9 to meet the extreme situations in police use and enable the flashlight to be put into use quickly.
