Description

Technical Field

[0002] Flashlights are a portable lighting tool used in modern life and industrial applications, and are widely used in various scenarios such as daily lighting, outdoor exploration, and emergency rescue.

[0003] Currently, most flashlights are equipped with only one switch, such as a single button switch for on / off control, or an external tail switch for triggering. This limited switching method makes it difficult to meet the needs of users in different usage scenarios. Integrating multiple independent switches into the same flashlight would take up a lot of space, which is often difficult to achieve within the limited internal space of a flashlight.

[0004] Therefore, there is an urgent need to develop a flashlight with a multi-functional switch to solve the above-mentioned technical problems. Utility Model Content

[0060] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0061] like Figures 1 to 18 As shown, this embodiment provides a flashlight with a multi-functional switch, including a body 100 and a tail cap assembly 200 connected to the body 100. In this embodiment, the head of the flashlight refers to the side of the light-emitting end, and the tail refers to the side of the handheld end. For ease of description, this embodiment uses... Figure 1 Taking the orientation shown as an example, the side closer to the light-emitting end is the bottom, and the side closer to the handheld end is the top.

[0062] The tail cover assembly 200 includes a tail cover 1, a push-button switch assembly 2, a mouse tail wire 3, and a rotary switch assembly 4.

[0063] The tail cap 1 is connected to the cylinder 100. A circuit board 300 is installed inside the tail cap 1, and the circuit board 300 is connected to the light-emitting component inside the cylinder 100. The light-emitting component inside the cylinder 100 is a mature existing technology in this field and will not be described in detail here.

[0064] The push button switch assembly 2 includes a movable component 21 and a first conductive element 22. The first conductive element 22 is disposed on the circuit board 300. The movable component 21 is partially disposed inside the tail cover 1 and has a hollow portion 210 inside. The movable component 21 can move along the axial direction of the tail cover 1 so that the movable component 21 contacts and conducts with the first conductive element 22, or moves the movable component 21 away from the first conductive element 22.

[0065] The rat-tail wire 3 includes a positive terminal 31 and a negative terminal 32. The movable component 21 includes a positive part and a negative part. The positive part is electrically connected to the positive terminal of the circuit board 300, and the negative part is electrically connected to the negative terminal of the circuit board 300. The rat-tail wire 3 can be inserted into the hollow part 210 so that the positive terminal 31 contacts the positive terminal and conducts, and the negative terminal 32 contacts the negative terminal and conducts.

[0066] The rotary switch assembly 4 is located on the tail cover 1 and is used to switch the light-emitting mode of the light-emitting assembly.

[0067] In practice, users can turn the flashlight on or off using the button switch assembly 2 or the mouse tail wire 3, and when the flashlight is on, they can further switch the light-emitting mode of the light-emitting component by rotating the switch assembly 4.

[0068] The specific operation of controlling the flashlight's on / off state via the push-button switch assembly 2 is as follows: When the user needs to turn on the flashlight, press the movable assembly 21 to move it down until the movable assembly 21 contacts the first conductive element 22. At this time, the circuit is connected, and the flashlight's light-emitting component is lit. When the user needs to turn off the flashlight, move the movable assembly 21 up to move away from the first conductive element 22. At this time, the circuit is disconnected, and the flashlight's light-emitting component is turned off.

[0069] The specific operation of controlling the flashlight's on / off state via the rat tail wire 3 is as follows: When the user needs to remotely control the flashlight's on / off state, this can be achieved by connecting the rat tail wire 3. Insert the rat tail wire 3 into the hollow part 210, so that the positive terminal 31 of the rat tail wire 3 contacts and conducts with the positive terminal of the movable component 21, and the negative terminal 32 of the rat tail wire 3 contacts and conducts with the negative terminal of the movable component 21. Since the positive and negative terminals are electrically connected to the positive and negative terminals of the circuit board 300 respectively, the circuit between the rat tail wire 3 and the circuit board 300 is now complete. The user can then turn the light-emitting component on or off using the external switch of the rat tail wire 3.

[0070] The flashlight with a multi-functional switch provided in this embodiment integrates a push-button switch assembly 2 and a mouse tail wire 3 in the tail cap assembly 200, offering two different on / off control methods to meet the user's operational needs in different scenarios. Furthermore, the mouse tail wire 3 can be inserted into the hollow portion 210 of the movable assembly 21 to achieve circuit conduction, resulting in a compact layout between the mouse tail wire 3 and the push-button switch assembly 2. Simultaneously, the rotary switch assembly 4 is placed in the tail cap 1, further enabling the switching function of the flashlight's light emission mode. This integration of multiple switch functions effectively solves the problems of existing flashlights having a single switch mode and the difficulty of implementing multiple switches in limited space, greatly improving the convenience and functionality of the flashlight.

[0071] like Figure 3 , Figures 8-12 As shown, in some embodiments, the movable component 21 includes a movable cylinder 211, a positive contact ring 212, and a negative contact ring 213. The movable cylinder 211 can contact or move away from the first conductive element 22. The positive contact ring 212 and the negative contact ring 213 are both connected inside the movable cylinder 211 and can move together with the movable cylinder 211. The positive contact ring 212 and the movable cylinder 211 are electrically connected to the positive electrode of the circuit board 300, and the negative contact ring 213 is electrically connected to the negative electrode of the circuit board 300. The space formed by the positive contact ring 212 and the negative contact ring 213 is a hollow part 210. The positive terminal 31 can contact and conduct with the positive contact ring 212, and the negative terminal 32 can contact and conduct with the negative contact ring 213.

[0072] With this configuration, the active component 21 is designed as a combination of an active cylinder 211, a positive contact ring 212, and a negative contact ring 213, forming an integrated and layered structural design. This provides precise insertion and conduction space for the positive terminal 31 and the negative terminal 32 of the mouse tail wire 3, effectively integrating the control functions of the button and the external mouse tail wire 3. While realizing multi-functional switch control within a limited space, it can also improve the reliability and stability of the circuit connection.

[0073] like Figure 8As shown, in some embodiments, the movable component 21 further includes a pressing member 214, which is sleeved and connected to the outer peripheral surface at the top position of the movable cylinder 211. The pressing member 214 is used for user operation. With this configuration, during actual operation, the user applies force to the pressing member 214, which is then transmitted to the movable cylinder 211, providing the user with a more convenient and comfortable point of force for operation.

[0074] like Figures 6-8 As shown, in some embodiments, a reset spring 5 is provided on the circuit board 300. The reset spring 5 is electrically connected to the negative terminal of the circuit board 300. A conductive ball head 6 is connected to the top of the reset spring 5. The reset spring 5 always has an elastic tendency to make the conductive ball head 6 abut against the bottom of the negative contact ring 213. The negative contact ring 213, the conductive ball head 6 and the reset spring 5 are electrically connected in sequence.

[0075] In practice, when the movable component 21 moves downward, it compresses the return spring 5. When the force applied by the user to the movable component 21 is removed, the return spring 5 gradually returns to its original position due to its own elastic force. During the return process, the return spring 5 pushes against the negative contact ring 213 and moves upward, thereby causing the movable component 21 to move upward as a whole, so that the movable component 21 moves away from the first conductive element 22. Furthermore, when the rat tail wire 3 is inserted into the hollow part 210, the negative terminal 32, the negative contact ring 213, the conductive ball head 6, and the return spring 5 are sequentially electrically connected and connected to the negative terminal of the circuit board 300, thus forming a conductive negative terminal circuit.

[0076] This design utilizes the elastic tendency of the return spring 5 to automatically reset the movable component 21, improving the convenience of turning off the flashlight and avoiding the need for continuous force from the user. Simultaneously, when the rat tail wire 3 is connected, a stable conductive path is formed through the negative contact ring 213, the conductive ball 6, and the return spring 5, ensuring circuit continuity in external control mode. Thus, a simple and compact design fulfills multiple functional requirements.

[0077] like Figure 8 As shown, in some embodiments, the movable component 21 further includes a first plastic sleeve 215 and a second plastic sleeve 216. The first plastic sleeve 215 and the second plastic sleeve 216 are connected to the inner peripheral wall of the movable cylinder 211. The first plastic sleeve 215 is located below the positive contact ring 212 and is sleeved on the outer periphery of the negative contact ring 213. The second plastic sleeve 216 is located below the negative contact ring 213. The conductive ball head 6 is located inside the second plastic sleeve 216.

[0078] With this setup, the insulation properties of the first plastic sleeve 215 and the second plastic sleeve 216 can be used to effectively physically isolate the positive and negative circuits, avoiding the risk of short circuits between the two circuits and improving circuit safety.

[0079] like Figure 5 , Figure 8 and Figure 10 As shown, in some embodiments, a second conductive element 7 is provided on the circuit board 300. The second conductive element 7 is connected between the movable cylinder 211 and the circuit board 300. The movable cylinder 211 is electrically connected to the positive terminal of the circuit board 300 through the second conductive element 7. The second conductive element 7 can extend and retract along the moving direction of the movable cylinder 211. That is, the positive terminal 31 of the rat tail wire 3 can be sequentially electrically connected to the positive contact ring 212, the movable cylinder 211, and the second conductive element 7, and conduct to the positive terminal of the circuit board 300 to form a conductive positive circuit. In addition, the second conductive element 7 can extend and retract along the moving direction of the movable cylinder 211, so that even when using the push-button switch function, the movement of the movable cylinder 211 does not affect its electrical connection with the second conductive element 7.

[0080] like Figure 6 and Figure 10 As shown, in some embodiments, the second conductive element 7 is configured as at least one of a conductive spring and a retractable current contact. That is, the second conductive element 7 can be just a conductive spring, or just a retractable current contact, or a combination of both.

[0081] In this embodiment, the second conductive element 7 is configured as a combination of a conductive spring and a retractable current probe, such as... Figure 6 and Figure 10 As shown, the conductive spring is sleeved around the retractable current contact pin, forming a dual conductive mechanism. If either the conductive spring or the retractable current contact pin fails, the other can still perform the conductive function, forming redundant protection and improving safety.

[0082] Optionally, the number of the second conductive element 7 can be set to multiple to enhance the conductivity, such as two or three, etc., and this application does not make a specific limitation.

[0083] like Figures 6-9 As shown, in some embodiments, the first conductive element 22 is configured as a conductive spring so that the first conductive element 22 can extend and retract along the moving direction of the movable cylinder 211.

[0084] With this setup, the elastic deformation capability of the conductive spring can adaptively compensate for the dimensional errors and positional deviations of the movable cylinder 211 during its travel. Even if there is a certain tolerance in the travel of the movable cylinder 211, the conductive spring can still maintain stable contact with the movable cylinder 211 through its own elasticity, ensuring reliable circuit conduction, which in turn helps to reduce the manufacturing precision requirements of the movable cylinder 211.

[0085] like Figures 6-9As shown, in some embodiments, a limiting member 8 is provided on the circuit board 300, and the first conductive member 22 is mounted on the limiting member 8 and partially located inside the limiting member 8. The limiting member 8 includes a top wall 81 that can stop the top of the first conductive member 22. It can be understood that when the movable cylinder 211 moves downward, it contacts the part of the first conductive member 22 located outside the limiting member 8.

[0086] With this setup, as the movable cylinder 211 moves upward, the first conductive element 22, which is in the form of a conductive spring, will gradually rebound. The top wall 81 of the limiting element 8 can stop the first conductive element 22 to limit the rebound height of the first conductive element 22, thereby ensuring that the first conductive element 22 returns to a fixed position each time, which helps to ensure the consistency of product operation.

[0087] Optionally, the first conductive element 22 can be configured as multiple, such as two or three, etc., and this application does not make a specific limitation.

[0088] Optionally, the limiting element 8 may be made of plastic, including but not limited to plastic.

[0089] like Figure 5 As shown, in some embodiments, the tail cap assembly 200 further includes a dust cap 9, which is inserted into the hollow portion 210 and covers the top opening of the hollow portion 210. When the flashlight is not in use, the dust cap 9 can effectively prevent dust, moisture, and foreign objects from entering the flashlight, which helps to ensure the service life of the flashlight.

[0090] The dust cap 9 can be set as another component connected to the tail cap assembly 200, or it can be set separately, depending on the actual situation.

[0091] like Figure 4 , Figure 8 and Figure 14 As shown, in some embodiments, the rotary switch assembly 4 includes a rotating element 41 and an optocoupler switch 42. The rotating element 41 is partially disposed inside the tail cover 1. The rotating element 41 is sleeved on the outer periphery of the movable cylinder 211 and can rotate around its own axis. A portion of the bottom surface of the rotating element 41 is configured as a reflective part 411, and the remaining portion is configured as a non-reflective part 412.

[0092] Optical coupler switch 42 is connected to the top surface of circuit board 300. The top surface of optical coupler switch 42 is the sensing surface 421. Optical coupler switch 42 includes an on state and an off state. The reflective part 411 can face and cooperate with the sensing surface 421 to make the optical coupler switch 42 in the on state. The non-reflective part 412 can face and cooperate with the sensing surface 421 to make the optical coupler switch 42 in the off state.

[0093] The optocoupler switch 42 is an independent surface-mount electronic component consisting of a transmitter and a receiver. The transmitter emits light, and the receiver receives the reflected light. The sensing surface 421 includes the active terminals of both the transmitter and receiver. When the rotating member 41 rotates to a position where the reflective part 411 is opposite to the sensing surface 421 of the optocoupler switch 42, the light emitted from the sensing surface 421 is blocked by the reflective part 411, which then reflects the light back to the sensing surface 421. The reflected light is received by the sensing surface 421, thus turning on the optocoupler switch 42. When the rotating member 41 rotates to a position where the non-reflective part 412 is opposite to the sensing surface 421 of the optocoupler switch 42, the non-reflective part 412 cannot reflect the light emitted from the sensing surface 421, and the sensing surface 421 does not receive the reflected light, thus turning off the optocoupler switch 42. The on and off states of the optocoupler switch 42 can transmit different electrical signals to the light-emitting component via the circuit board 300, thereby putting the light-emitting component into different light-emitting modes.

[0094] With this setup, users can switch the optocoupler switch 42 between the on and off states by rotating the rotating part 41, relying on the principle of light reflection. This allows the light-emitting component to switch between different light-emitting modes, achieving non-contact operation. This effectively avoids component wear caused by contact conduction and also prevents false triggering, being locked in a fixed lighting mode, or interference from multiple magnetic field sources caused by magnetic attraction when switching light-emitting modes. This allows the flashlight to accurately perform its intended function, improving the flashlight's working stability and reliability.

[0095] like Figures 15-18 As shown, in some embodiments, multiple optocoupler switches 42 are provided, each optocoupler switch 42 including a sensing surface 421, and a reflective portion 411 is configured to face at least one sensing surface 421. That is, when the rotating member 41 rotates to any position, the reflective portion 411 faces the sensing surface 421 of at least one optocoupler switch 42, causing at least one optocoupler switch 42 to be turned on. With this configuration, the flashlight can be in multiple different power levels by varying the relative positions of the reflective portion 411 and the multiple optocoupler switches 42, with each power level corresponding to a light-emitting mode of the light-emitting component.

[0096] like Figures 15-18 As shown, in this embodiment, there are two optocoupler switches 42. When the reflective part 411 is opposite to the sensing surface 421 of one of the optocoupler switches 42, the other optocoupler switch 42 is opposite to the non-reflective part 412. When the reflective part 411 is opposite to the sensing surface 421 of both optocoupler switches 42, the non-reflective part 412 is opposite to other positions on the top surface of the circuit board 300.

[0097] Specifically, for ease of description, it will be along... Figures 16-18The first optocoupler switch 42 rotated counterclockwise is called the first switch, and the second optocoupler switch 42 is called the second switch. When the rotating part 41 is in its default initial position (i.e., position one), the reflector 411 is positioned above the first switch. Figure 16 The first switch receives reflected light and is in the ON state, while the second switch does not receive reflected light and is in the OFF state. The rotating member 41 rotates counterclockwise from position one to position two. At this time, the reflective part 411 is located above the first and second switches. Figure 17 Both the first and second switches can receive reflected light and are in the ON state, while the non-reflective part 412 is opposite to other positions on the top surface of the circuit board 300. Furthermore, the rotating part 41 continues to rotate counterclockwise, switching from position two to position three. At this time, the reflective part 411 is positioned above the second switch. Figure 18 The first switch has a non-reflective part 412 above it. The second switch can receive reflected light and is in the ON state, while the first switch cannot receive reflected light and is in the OFF state. Positions one, two, and three correspond to three light-emitting modes of the light-emitting component. For example, the light-emitting component in position one emits white light, the light-emitting component in position two emits IR light, and the light-emitting component in position three emits UV light.

[0098] In another possible embodiment, the non-reflective portion 412 is configured to face all of the multiple sensing surfaces 421. Taking the aforementioned example of having two optocoupler switches 42, the non-reflective portion 412 is located above the two optocoupler switches 42, and both optocoupler switches 42 are unable to receive reflected light and are in an open state. The reflective portion 411 is then opposite to other positions on the top surface of the circuit board 300. This position can be set to position four, corresponding to the fourth light-emitting mode of the light-emitting component (such as emitting blue light), to further enrich the light-emitting function of the flashlight.

[0099] Of course, in other embodiments, the optocoupler switches 42 can also be set to three, four, etc., depending on the actual situation. For example, when there are three optocoupler switches 42 (including the first switch, the second switch, and the third switch), as the rotating member 41 rotates, when only the first switch has a corresponding reflective part 411, it is position one; when the first and second switches have corresponding reflective parts 411, it is position two; when the first, second, and third switches all have corresponding reflective parts 411, it is position three; when the second and third switches have corresponding reflective parts 411, it is position four; when only the third switch has a corresponding reflective part 411, it is position five; when the first, second, and third switches do not have corresponding reflective parts 411, but instead correspond to non-reflective parts 412, it is position six. Positions one to six correspond to the six different light emission modes of the light-emitting component.

[0100] like Figure 4 and Figure 8 As shown, in some embodiments, the rotary switch assembly 4 further includes a gear adjustment knob 43, and the rotating member 41 includes an extension section protruding from the top wall of the tail cover 1. The gear adjustment knob 43 is sleeved and connected to the outer periphery of the extension section, and the gear adjustment knob 43 can drive the rotating member 41 to rotate.

[0101] With this setup, the user can hold the gear shift knob 43 and drive the rotating component 41 to rotate by turning the gear shift knob 43. Compared to directly operating the rotating component 41, the gear shift knob 43 significantly increases the contact area of ​​operation, making it easier for the user to hold and exert force.

[0102] like Figure 4 As shown, in some embodiments, the distance between each point of the reflective portion 411 facing the corresponding sensing surface 421 and the sensing surface 421 is less than or equal to the receivable distance of the sensing surface 421, and the distance between each point of the non-reflective portion 412 facing the corresponding sensing surface 421 and the sensing surface 421 is greater than the receivable distance of the sensing surface 421.

[0103] This design, which uses distance difference to switch between reflective and non-reflective states, allows for precise control of distance parameters through mold processing, resulting in a simple and reliable structure. When the reflective part 411 maintains an effective distance from the sensing surface 421, the reflected signal can be stabilized; the non-reflective part 412, being outside the sensing range, can completely block the signal, thereby achieving clear gear switching and effectively avoiding signal interference and misjudgment.

[0104] In another possible embodiment, the distinction between the reflective portion 411 and the non-reflective portion 412 can be achieved without a distance difference. For example, a light-absorbing material (such as a black oxide coating or a carbon-based light-absorbing paint) can be provided at a position adjacent to the reflective portion 411. When light is projected onto this position, it will be absorbed by the light-absorbing material and will not be reflected. The part where the light-absorbing material is provided is the non-reflective portion 412.

[0105] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
