Description

Technical Field

[0001] This utility model relates to the field of switch technology, and more specifically, to a switch and a flashlight. Background Technology

[0002] In the field of portable lighting, switches play a crucial role as control units, serving as a communication bridge between users and lighting equipment. With technological advancements and increasingly diversified consumer demands, modern portable lighting products not only pursue high-efficiency lighting output but also emphasize convenient operation and superior reliability.

[0003] Existing switches rely on the closing and opening of physical contacts to connect and disconnect circuits. When a user presses the switch button, the internal contacts come into contact, forming a circuit and turning the power to the lighting equipment on or off. However, this direct physical contact becomes a major hidden danger over long-term use. Due to frequent pressing, wear gradually accumulates between the contacts, eventually leading to complete wear and loss of conductivity, causing the switch to malfunction and resulting in low functional stability.

[0034] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Switches are widely used control units in the field of portable lighting products. With the development of portable lighting products, the requirements for product operation and reliability are getting higher and higher. Traditional contact switches require contact to conduct or contact to provide feedback signals. Long-term pressing will cause wear on the contact points, resulting in the risk of switch failure.

[0036] To solve the above problems, see [reference] Figures 1 to 15As shown, this utility model provides a switch, which includes: a mounting base; a movable component, the movable component being movable along a first direction toward or away from the mounting base, the movable component including a movable part having at least two trigger positions, a light guide structure being provided at one end of the movable part facing the mounting base, the light guide structure including at least two light guide parts, the at least two light guide parts being sequentially arranged on the movable part along the first direction; a control component, mounted on the mounting base, the control component including a beam emitting unit and a beam receiving unit, the beam receiving unit including at least two beam receiving parts, the beam receiving parts being configured to emit a first control signal, the first control signals emitted by the at least two beam receiving parts being different; the at least two trigger positions are related to at least two types of first control signals. Each control signal corresponds to a different trigger position. When the moving part moves to different trigger positions, the light guide part at the corresponding height can guide the light beam emitted by the light beam emitting unit to the corresponding light beam receiving part, so that the light beam receiving part emits the corresponding first control signal. The housing has a receiving cavity, and the mounting base is installed in the receiving cavity. Multiple magnetic induction elements 12 are provided on the mounting base, and the multiple magnetic induction elements 12 are spaced apart along the circumference of the mounting base. The annular adjustment member is sleeved on the housing and can rotate relative to the housing. Two magnetic elements are provided on the annular adjustment member. Each magnetic induction element 12 can sense the magnetic element located in its sensing area and generate a second control signal. Two adjacent magnetic induction elements 12 form a sensing unit. The second control signals generated by different sensing units are different.

[0037] In this embodiment, the moving part 21 has at least two trigger positions, each trigger position corresponding to a first control signal, and the first control signals corresponding to different trigger positions are different. The beam emitting unit 32 is capable of emitting a beam, and each beam receiving part 31 is capable of emitting a first control signal.

[0038] By sequentially arranging at least two light guides 90 along a first direction on the moving part 21, and each light guide 90 being able to guide the beam emitted by the beam emitting unit 32 to the corresponding beam receiving part 31, multi-level control of the switch is achieved. When the user moves the moving part 21 to different trigger positions, the control component 30 can generate different first control signals to execute different functions. For example, one trigger position can be used to turn on the device, while another position can be used to adjust the brightness or switch modes. In addition, the beam guiding and receiving are non-contact, that is, the signal transmission has no physical contact delay, and the response speed can reach the nanosecond level, which significantly improves the operating sensitivity and response speed of the switch. Furthermore, this non-contact design avoids mechanical wear, and even after long-term or frequent operation, the optical path between the light guide 90 and the beam receiving part 31 can still remain stable, improving the durability and reliability of the switch.

[0039] For ease of understanding, the operation of the switch will be explained using the example of the moving part 21 having two trigger positions. For clarity, the two trigger positions are named the first trigger position and the second trigger position, respectively. The two first control signals are named the first control signal a and the first control signal b, respectively. The first control signal a and the first control signal b are emitted by two beam receiving parts 31, respectively. For clarity, the beam receiving part 31 that emits the first control signal a is now named the first beam receiving part, and the beam receiving part 31 that emits the first control signal b is named the second beam receiving part. The first trigger position corresponds to the first control signal a; that is, when the moving part 20 moves to the first trigger position, the control part 30 emits the first control signal a. The second trigger position corresponds to the first control signal b; that is, when the moving part 20 moves to the second trigger position, the control part 30 emits the first control signal b. When the moving part 21 moves along the first direction to the first trigger position, the light guide part 90 can change the movement path of the beam emitted by the beam emitting unit 32, guiding the beam emitted by the beam emitting unit 32 to the first beam receiving part. After receiving the beam, the first beam receiving part generates the first control signal a. When the moving part 21 continues to move along the first direction until it reaches the second trigger position, the light beam emitted by the light beam emitting unit 32 is guided to the second light beam receiving part via the light guide part 90. After receiving the light beam, the second light beam receiving part generates a first control signal b. As can be seen from the above, the switch of this application changes the optical path of the light beam through the light guide part 90, guiding the light beam to the corresponding light beam receiving part 31, thereby realizing the emission of different first control signals. Compared with the prior art, which relies on the closing and opening of physical contact points to realize the conduction and disconnection of the circuit, it can avoid the wear of contact points, thereby significantly improving the functional stability of the switch.

[0040] The housing 40's receiving cavity 41 effectively protects the internal light guide structure, beam emitting unit 32, and beam receiving unit 31 from external physical impacts and environmental factors. "Multiple" refers to two or more, not including two. By arranging multiple magnetic induction elements 12 circumferentially at intervals along the mounting base, each magnetic induction element 12 has its specific sensing area. When the annular adjustment member 200 rotates, the magnetic element 202 successively enters the sensing area range of different sensing units. When the magnetic element 202 rotates into the sensing area range of the sensing unit under the drive of the annular adjustment member 200, the two magnetic elements 202 correspond one-to-one with the two magnetic induction elements 12 constituting the sensing unit. Since different sensing units generate different second control signals, this means that the switch can emit different second control signals according to the position of the magnetic element 202, thereby realizing the control of various functions or states of the device. For example, functions such as brightness adjustment and flash mode switching can be realized without complex physical mechanical structures. Furthermore, the above arrangement avoids the traditional physical contact control method, instead using magnetic field induction to send the second control signal. The interaction between the magnetic component 202 and the magnetic induction component 12 is non-contact, which can significantly reduce the failure rate caused by mechanical wear and thus extend the overall service life of the switch.

[0041] It should be noted that this application controls different paths of the light beam so that the light beam signal is received by different light beam receiving units 31, thereby realizing the control of the switching function. Compared with the traditional contact type, the switch of this application has no physical contact wear, and its durability and reliability are higher than the contact type conduction of the traditional mechanical switch. In addition, the switch signal transmission speed is 0.01ms, which is more than 3000 times the response speed of the traditional mechanical switch. As can be seen from the above, the response speed of the switch of this application is faster and more sensitive than the traditional mechanical contact switch, and the contactless signal control can improve the reliability and durability of the switch.

[0042] In one embodiment, the beam emitting unit 32 is an infrared emitting diode, and the beam receiving unit 31 is an infrared receiving diode.

[0043] In one embodiment, the mounting base 10 is a circuit board.

[0044] In one embodiment, the magnetic element 202 is a permanent magnet.

[0045] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the spacing between two adjacent magnetic induction elements 12 is equal.

[0046] The above settings can create a relatively uniform magnetic field distribution, thereby ensuring the consistency of magnetic field induction effects at different locations.

[0047] See also Figures 1 to 15As shown, in one embodiment of the present invention, the switch further includes a positioning structure 300. The inner peripheral wall of the annular adjusting member 200 is provided with a plurality of slots 201. The plurality of slots 201 are arranged at intervals along the circumference of the annular adjusting member 200. The positioning structure 300 has a positioning state in which it is engaged in the slots 201 and a disengaged state in which it is disengaged from the slots 201.

[0048] In this embodiment, "multiple" refers to two or more. The number of slots 201 is the same as the number of sensing units, and each slot 201 corresponds one-to-one with a sensing unit. When the positioning structure 300 is engaged in the slot 201, it can position the annular adjustment member 200, thereby allowing the magnetic member 202 to stop at the designated sensing unit position and emit the corresponding second control signal. Simultaneously, by engaging the positioning structure 300 in the slot 201, accidental rotation of the annular adjustment member 200 during use can be prevented, reducing misoperation caused by device shaking or unintentional user contact.

[0049] See also Figures 1 to 15 As shown, in one embodiment of the present invention, a mounting groove 46 is provided on the housing, and a positioning structure 300 is installed in the mounting groove 46. The positioning structure 300 includes a positioning member 301 and a first elastic member 302. The positioning member 301 is located between the first elastic member 302 and the annular adjusting member 200. The positioning member 301 elastically abuts against the first elastic member 302 and can be inserted into the slot 201 under the elastic force of the first elastic member 302.

[0050] With the above settings, it is possible to install the positioning structure 300 and switch the positioning structure 300 between the positioning state and the disengagement state.

[0051] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the positioning member 301 is a spherical structure, and the positioning structure 300 further includes a mounting shell 303. The mounting shell 303 is installed in the mounting groove 46 of the shell, and the first elastic member 302 is installed in the inner cavity of the mounting shell 303. A portion of the positioning member 301 is located in the inner cavity of the mounting shell 303. The opening of the mounting shell 303 is smaller than the maximum diameter of the positioning member 301, which can limit the positioning member 301 in the circumferential direction.

[0052] In one embodiment, the positioning element 301 can be an iron ball.

[0053] In one embodiment, the number of magnetic induction elements 12 is even.

[0054] In this embodiment, when the two magnetic elements rotate to the sensing unit composed of two adjacent magnetic induction elements 12, the two magnetic elements correspond one-to-one with the two magnetic induction elements 12. An even number of distributed magnetic induction elements 12 can reduce interference between signals.

[0055] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the light guide structure further includes at least two light-focusing structures 100. The light-focusing structures 100 are configured to focus the light beam emitted by the light beam emitting unit 32. The light-focusing structures 100 are arranged toward the light beam emitting end of the light beam emitting unit 32. At least two light-focusing structures 100 are arranged in a one-to-one correspondence with at least two light guide parts 90. The light guide part 90 can guide the light beam focused by the light-focusing structure 100 arranged with itself to the corresponding light beam receiving part 31.

[0056] In this embodiment, the focusing structure 100 is configured to focus the light beam emitted by the beam emitting unit 32. This concentrates the energy of the beam during propagation, increasing the intensity of the beam received by the beam receiving unit 31, thereby enhancing signal stability and reliability. Simultaneously, the focusing of the beam by the focusing structure 100 reduces scattering and energy loss in the air, allowing the beam to be guided more efficiently to the corresponding beam receiving unit 31. Even at long distances or under complex optical path conditions, the integrity and intensity of the first control signal can be maintained. At least two focusing structures 100 are correspondingly arranged with at least two light guides 90, enabling each light guide 90 to accurately receive and guide the beam focused by its corresponding focusing structure 100. This precise optical path control ensures accurate beam guidance at different triggering positions.

[0057] In one embodiment, the light-concentrating structure 100 is a Fresnel lens.

[0058] See also Figures 1 to 15 As shown, in one embodiment of the present invention, a beam emitting unit and at least two beam receiving parts are arranged at circumferential intervals along the mounting base. The beam emitting end of the beam emitting unit is located on the moving path of the focusing structure, and the beam emitting end of the beam emitting unit is arranged facing the focusing surface of the focusing structure.

[0059] The above configuration ensures that the beam emitted from the beam emitting unit is captured by the focusing structure and transmitted along a predetermined path. It also enables the beam to be focused and oriented to the maximum extent during transmission, reducing unnecessary scattering and energy loss, and improving the efficiency and accuracy of beam transmission.

[0060] See also Figures 1 to 15As shown, in one embodiment of the present invention, a first boss 11 is provided on the mounting base 10, and a clearance channel 111 is provided on the first boss 11. The beam emitting unit 32 and at least two beam receiving parts 31 are all mounted on the top of the first boss 11, and the beam emitting unit 32 and at least two beam receiving parts 31 are all located on the outer periphery of the clearance channel 111. The clearance channel 111 is configured to allow all light guide parts 90 to enter.

[0061] In this embodiment, by providing a first protrusion 11 on the mounting base 10, a stable mounting position can be provided for the beam emitting unit 32 and the beam receiving unit 31. The design of the clearance channel 111 allows the light guide 90 and the focusing structure 100 to move freely in the first direction without physical interference with the beam emitting unit 32 and the beam receiving unit 31, ensuring unobstructed optical path and accurate transmission of the first control signal. By centrally arranging the beam emitting unit 32 and the beam receiving unit 31 on the top of the first protrusion 11, while the light guide 90 and the focusing structure 100 can move to the trigger position through the clearance channel 111, this layout optimizes the use of space inside the device, enabling the switch to achieve complex functions within a limited space while maintaining structural compactness and layout rationality.

[0062] In one embodiment, the light guide 90 is a reflector or a reflective prism.

[0063] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the switch further includes a limiting cover 50, which is fixedly installed on the top of the housing 40. The moving component 20 also includes a pressing part 22, with one end of the moving part facing the mounting base located in the receiving cavity. The pressing part is connected to the end of the moving part away from the mounting base. The limiting cover is provided with a first through hole 51 for the pressing part to pass through at the position corresponding to the pressing part, and the limiting cover can form a stop and limit the pressing part in the first direction.

[0064] In this embodiment, the movable part 21 can move towards or away from the mounting base 10 along a first direction. The limiting cover 50 is fixed to the top of the housing 40 and can stop and limit the pressing part 22 in the first direction, preventing the pressing part 22 from falling out of the housing 40. The cooperative use of the movable part 21 and the pressing part 22 allows the user to precisely control the movement of the movable part 21 in the first direction through a pressing operation, so that the movable component 20 can move to different trigger positions. At the same time, the setting of the pressing part 22 allows the user to operate the switch through an intuitive pressing action, simplifying the operation process and improving the convenience and comfort of operation.

[0065] See also Figures 1 to 15As shown, in one embodiment of this utility model, there are two trigger positions. The switch also includes a first elastic reset structure 60 and a second elastic reset structure 70. The second elastic reset structure 70 is disposed on the moving path of the pressing part 22. A first stop part 42 and a second stop part are disposed in the receiving cavity 41 at intervals along a first direction. The second elastic reset structure 70 is installed in the receiving cavity 41 and is located between the pressing part 22 and the first stop part 42. The first elastic reset structure 60 is sleeved on the first end of the moving part 21, and the first end of the first elastic reset structure 60 is connected to the moving part 21. The second end of the elastic reset structure 60 elastically abuts against the first stop portion 42. The second elastic reset structure 70 includes a moving body 71 and at least two second elastic members 72. One end of the second elastic member 72 is sleeved on the moving body 71, and the other end of the second elastic member 72 elastically abuts against the first stop portion 42. When the pressing portion 22 compresses the first elastic reset structure 60 until the bottom of the pressing portion 22 abuts against the top surface of the moving body 71, the control component 30 is in the first trigger position. When the moving body 71 compresses the second elastic member 72 until the pressing portion 22 abuts against the second stop portion, the control component 30 is in the second trigger position.

[0066] In this embodiment, there are two trigger positions, enabling the switch to achieve two-order control. For ease of description, the two trigger positions are named the first trigger position and the second trigger position, respectively. The first trigger position corresponds to a lighter pressing action, activating a simple function, such as turning on the device. The second trigger position requires a greater pressing force to trigger a more complex function, such as brightness adjustment or mode switching, enhancing the versatility and flexibility of the switch. The contact between the pressing part 22 and the top surface of the moving body 71 provides tactile feedback, allowing the user to realize that the moving component 20 has reached the first trigger position. The contact between the pressing part 22 and the second stop indicates that the moving component 20 has reached the second trigger position.

[0067] Furthermore, the first stop 42 and the second stop ensure that the pressing part 22 stops precisely at different trigger positions, avoiding control instability caused by excessive or insufficient pressing. Moreover, the first elastic reset structure 60 and the second elastic element 72 can quickly reset the pressing part 22 and the moving part 21 to their initial positions after the pressing is released, reducing the risk of control delay or failure caused by physical wear or equipment vibration, and improving the long-term stability and reliability of the switch.

[0068] In one embodiment, both the first elastic reset structure 60 and the second elastic element 72 are springs.

[0069] See also Figures 1 to 15As shown, in one embodiment of the present invention, a second protrusion 43 is provided on the side of the first stop portion 42 facing the limiting cover 50. The second protrusion 43 is provided with a second through hole 431 for the moving portion 21 to pass through at the position corresponding to the moving portion 21. Part of the moving portion 21 can pass through the second through hole 431. The second end of the first elastic reset structure 60 is sleeved on the second protrusion 43.

[0070] In this embodiment, the second end of the first elastic reset structure 60 is sleeved on the second boss 43, providing a stable fulcrum for elastic reset. When the pressing part 22 is released, the first elastic reset structure 60 enables the moving part 21 to accurately reset, ensuring that the moving component 20 returns to its initial position after each operation.

[0071] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the second stop portion includes a protrusion structure 44. When the control component 30 is in the second trigger position, the protrusion structure 44 can form a stop limit on the pressing portion 22 along the first direction.

[0072] With the above settings, it can be ensured that the moving component 20 continues to move toward the mounting base 10 when it reaches the second trigger position, thereby preventing the user from excessively pressing and damaging the internal optical path structure.

[0073] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the movable body 71 includes an annular body 711, at least two limiting portions 712 and at least two guiding portions 713. The at least two guiding portions 713 are correspondingly arranged with at least two second elastic members 72. One end of each second elastic member 72 is sleeved on the outer periphery of the corresponding guiding portion 713, and the other end of each second elastic member 72 abuts against the first stop portion 42. The at least two guiding portions 713 and the at least two limiting portions 712 are arranged at intervals along the circumference of the annular body 711. The protruding structure 44 includes at least two clearance notches 441. The at least two clearance notches 441 are correspondingly arranged with at least two guiding portions 713. The clearance notches 441 are configured to allow the guiding portions 713 corresponding to them to pass through. The housing 40 is provided with a limiting groove 45. The at least two limiting portions 712 are slidably arranged in the limiting groove 45 along a first direction.

[0074] In this embodiment, one end of each second elastic member 72 is sleeved on the outer periphery of the guide portion 713 and engaged on the annular body 711, while the other end of each second elastic member 72 elastically abuts against the first stop portion 42. The guide portion 713 can limit the second elastic member 72 in the radial direction, while the design of the clearance notch 441 allows the guide portion 713 to pass smoothly through the protruding structure 44, thereby ensuring that the pressing portion 22 can continue to press downward. At least two limiting portions 712 are slidably disposed in the limiting groove 45 along the first direction, which can ensure that the annular body 711 can move in the first direction toward or away from the first stop portion 42, and also prevent the annular body 711 from falling out of the receiving cavity 41. By integrating the guide portion 713, the limiting portion 712, and the second elastic member 72 onto the annular body 711, the structure is compacted, saving space inside the switch.

[0075] In one embodiment of the present invention, during the process of the moving component 20 moving to the trigger position, both the beam emitting unit 32 and the beam receiving part 31 are gap-fitted with the light guide structure.

[0076] With the above configuration, on the one hand, signal attenuation or interruption caused by direct contact or physical wear can be reduced, so that the optical signal can be stably transmitted from the beam emitting unit 32 to the beam receiving unit 31, improving the reliability and stability of the switch signal transmission. On the other hand, the gap fit avoids direct contact between the beam emitting unit 32, the beam receiving unit 31 and the light guide structure, reducing wear and potential failures of components during long-term use. The non-contact signal transmission method extends the service life of the switch and reduces maintenance frequency and cost.

[0077] See also Figures 1 to 15 As shown, in one embodiment of the present invention, the switch further includes an annular seal 80. The inner wall of the second boss 43 is provided with an annular groove 432. The annular seal 80 is installed in the annular groove 432, and the annular seal 80 can form a sealing fit with the outer wall surface of the moving part 21.

[0078] Through the above-described configuration, the sealing fit between the annular seal 80 and the outer wall of the moving part 21 significantly enhances the switch's waterproof and dustproof performance. Even in harsh environments, such as high humidity, dusty, or wet environments, the annular seal 80 can effectively prevent moisture and dust from entering the switch, protecting electronic components and optical path structures from damage and extending the switch's service life.

[0079] According to another aspect of the present invention, a flashlight is also provided, comprising: a body; and a switch as described above, the switch being mounted on the body.

[0080] In this embodiment, the flashlight switch has all the technical solutions and effects of the above-mentioned switch, which will not be repeated here.

[0081] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: A mounting base, a moving component, and a control component are provided. The control component includes a beam emitting unit and a beam receiving unit. The beam receiving unit includes at least two beam receiving parts. The moving component includes a moving part, on which at least two light guiding parts are sequentially arranged along a first direction. By changing the optical path of the beam through the light guiding parts, the beam is guided to the corresponding beam receiving part, thereby realizing the emission of different first control signals. Compared with the prior art, which relies on the closing and opening of physical contact points to realize the conduction and disconnection of the circuit, this method can avoid wear of the contact points, thereby significantly improving the functional stability of the switch.
