Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mobile lighting equipment technology, and in particular relates to a multi-mode integrated flashlight tail structure and flashlight. Background Technology
[0002] As a widely used portable lighting tool, the ease of use and safety of flashlights are always core concerns for users. While traditional tail-mounted push-button switches are simple and direct, they are easily triggered by accidental pressure or impact during carrying or storage, leading to unnecessary power depletion and potentially causing overheating and other safety hazards. To address this issue, existing technologies typically employ two strategies: one is to add a separate mechanical locking switch to the flashlight body, requiring the user to operate this switch separately to disable the main switch; the other is to use a long press on the main switch for a specific time to lock and unlock. However, the former increases structural complexity and user operation steps, making the overall design cumbersome; the latter fails to fundamentally solve the problem of accidental activation, especially under sustained pressure, which can still accidentally unlock the device.
[0003] On the other hand, with the widespread use of rechargeable batteries in flashlights, a charging port on the flashlight body has become standard. To ensure the port's dust and water resistance, a separate rubber protective plug is usually added. While this design provides some protection, it also brings significant inconvenience: users must repeatedly insert and remove the plug when charging, which is not only cumbersome but also poses a risk of the plug being lost, aging, or breaking, leading to seal failure. Furthermore, the additional plug and receiving slot further increase the complexity and size of the flashlight's structure, affecting its overall aesthetics and portability.
[0004] It is evident that existing flashlight designs generally suffer from drawbacks such as fragmented functions, redundant structures, and cumbersome operation in addressing the two key issues of accidental locking and charging interface protection.
[0005] Therefore, there is an urgent need for a multi-mode integrated flashlight tail structure and flashlight. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a multi-state integrated flashlight tail structure and flashlight, which achieves efficient integration of charging interface management, switch locking and unlocking status control, and enables multi-state switching through a single operation, simplifying the operation logic and improving the user experience.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A multi-state integrated flashlight tail structure includes:
[0009] The cylindrical body has a charging port on its side and a charging interface corresponding to the charging port inside the cylindrical body.
[0010] A switch assembly located at one end face of the cylinder and a locking mechanism located inside the cylinder, the locking mechanism being used to lock or unlock the switch assembly;
[0011] A tail cap is rotatably fitted onto the cylinder near the end where the switch assembly is located. When the tail cap rotates, it controls the locking mechanism to lock or unlock the switch assembly. The tail cap has an interface window. When the tail cap rotates to the point where the interface window corresponds to or is offset from the charging port, the charging port will be exposed or hidden.
[0012] Furthermore, when the tail cap rotates relative to the cylinder, it will switch between the following states:
[0013] Charging state: The charging interface is in an exposed state;
[0014] Ready state: The charging interface is in a hidden state and the switch component is in an unlocked state;
[0015] Locked state: The charging interface is in a hidden state and the switch assembly is in a locked state.
[0016] Furthermore, the side of the cylinder is provided with a lock hole that communicates with the inside of the cylinder. The locking mechanism includes a pin that is movably installed at the lock hole. The inner side of the tail cover is provided with a locking block. When the tail cover is rotated so that the locking block corresponds to the pin, the locking block will push the pin to engage with the switch assembly, so that the switch assembly cannot be pressed.
[0017] Furthermore, the locking mechanism also includes a spring fitted onto the pin, the spring being used to tend the pin away from the switch assembly.
[0018] Furthermore, the inner side of the tail cover is provided with multiple positioning grooves. When the tail cover is rotated to the locked or unlocked state of the switch assembly, or when the tail cover is rotated to the exposed or hidden state of the charging interface, the pin will fall into the positioning groove under the elastic force of the spring.
[0019] Furthermore, the switch assembly includes a switch disposed inside the cylinder and a keycap disposed at the end face of the cylinder and connected to the switch. The keycap has a locking groove on its side, and the keycap will be axially locked when the pin is engaged in the locking groove.
[0020] Optionally, the locking mechanism includes a Hall element disposed inside the cylinder and electrically connected to the switch assembly, and the tail cover is provided with a magnetic element, which cooperates with the Hall element to lock or unlock the switch assembly.
[0021] Furthermore, an indicator light is provided on the side of the cylinder, and a light hole is provided on the side of the tail cap. When the charging interface is exposed, the light hole corresponds to the indicator light.
[0022] Furthermore, a limiting block is provided on the side of the cylinder, and a limiting groove is provided on the inner side of the tail cap. When the tail cap rotates relative to the cylinder, the limiting block will slide in the limiting groove.
[0023] This utility model also provides a flashlight, including the aforementioned multi-state integrated flashlight tail structure.
[0024] The beneficial effects of this utility model are:
[0025] This invention achieves simultaneous control of the lock / unlock state of the switch assembly and the exposed / hidden state of the charging interface with a single rotational action by linking the rotatable tail cap, locking mechanism, charging port, and interface window. This allows users to quickly switch between different functional states. The physical locking of the switch assembly is achieved through the cooperation of a movable pin and a tail cap locking block. A positioning groove is provided on the inside of the tail cap, and a spring is used to allow the pin to fall into the groove, facilitating user perception of the state switch. The precise limitation of the tail cap's rotation angle relative to the cylinder is achieved through the cooperation of a limiting block on the cylinder and a limiting groove on the tail cap. This invention achieves efficient integration of charging interface management, switch locking, and unlocking state control, enabling multi-state switching with a single operation, simplifying the operation logic and improving the user experience.

[0040] See appendix Figure 1 To be continued Figure 9 The figure shows a specific embodiment of the multi-state integrated flashlight tail structure and flashlight provided by this utility model.
[0041] See appendix Figure 2 The multi-state integrated flashlight tail structure includes:
[0042] The cylindrical body 1 has a charging port 110 on its side and a charging interface 2 inside the cylindrical body 1 that corresponds to the charging port 110.
[0043] A switch assembly 3 is located at one end face of the cylinder 1 and a locking mechanism 4 is located inside the cylinder 1. The locking mechanism 4 is used to lock or unlock the switch assembly 3.
[0044] A tail cover 5 is rotatably fitted onto the end of the cylinder 1 near the switch assembly 3. When the tail cover 5 rotates, it controls the locking mechanism 4 to lock or unlock the switch assembly 3. The tail cover 5 is provided with an interface window 510. When the tail cover 5 rotates to the point where the interface window 510 corresponds to or is offset from the charging port 110, the charging interface 2 will be exposed or hidden.
[0045] See appendix Figure 2In the above embodiment, the tail cap 5 is fitted onto the body 1, and switching between multiple states is achieved by rotating the tail cap 5. Specifically, on one hand, the interface window 510 on the tail cap 5 is linked to the charging port 110 on the body 1. When charging is needed, simply rotate the tail cap 5 until the interface window 510 corresponds to the charging port 110, at which point the charging interface 2 will be exposed and can be connected to an external charging cable for charging. Conversely, after charging is complete, rotating the tail cap 5 will offset the interface window 510 from the charging port 110, and the charging interface 2 will be hidden by the tail cap 5, achieving a dustproof effect. On the other hand, the tail cap 5 is linked to the locking mechanism 4 to lock or unlock the switch assembly 3. When the flashlight needs to be used for illumination, rotating the tail cap 5 will unlock the locking mechanism 4, allowing the switch assembly 3 to be pressed for illumination. When the flashlight needs to be stored, rotating the tail cap 5 will lock the locking mechanism 4, preventing accidental activation of the switch assembly 3. This embodiment allows users to quickly switch between different functional states with a single rotation action, making operation convenient.
[0046] See appendix Figure 3 To be continued Figure 5 In the above embodiment, when the tail cap 5 rotates relative to the body 1, it switches between three states: charging, ready, and locked. Specifically, the charging state means the charging interface 2 is exposed; the ready state means the charging interface 2 is hidden and the switch component 3 is unlocked; and the locked state means the charging interface 2 is hidden and the switch component 3 is locked. In this embodiment, based on the charging state, when the user rotates the tail cap 5 clockwise, it switches to the ready state, at which point the flashlight can be turned on by pressing the switch component 3. Based on the charging state, when the user rotates the tail cap 5 counterclockwise, it switches to the locked state, at which point pressing the switch component 3 will not turn on the flashlight. This embodiment enables the user to intuitively understand and quickly locate the current flashlight function status, and the state switching logic is clear and reliable.
[0047] See appendix Figure 2 and attached Figure 7 In the above embodiment, the side of the cylinder 1 is provided with a locking hole 120 communicating with the inside of the cylinder 1. The locking mechanism 4 includes a pin 410 movably installed in the locking hole 120. The inner side of the tail cover 5 is provided with a locking block 520. When the tail cover 5 rotates to the position where the locking block 520 corresponds to the pin 410, the locking block 520 will push the pin 410 to engage with the switch assembly 3, so that the switch assembly 3 cannot be pressed. In this embodiment, the mechanical force of the rotation of the tail cover 5 directly pushes the pin 410 to engage with the switch assembly 3, making the physical locking of the switch assembly 3 reliable, direct, simple and effective. The locking mechanism 4 in this embodiment includes two symmetrically arranged pins 410 that extend radially from the side of the cylinder 1 towards the center of the cylinder 1.
[0048] See appendix Figure 2 and attached Figure 6 In the above embodiment, the locking mechanism 4 further includes a spring 420 sleeved on the pin 410. The spring 420 is used to cause the pin 410 to tend away from the switch assembly 3. In the embodiment, the spring 420 is used to realize the automatic reset of the pin 410 when no external force is applied, so that the tail cover 5 can automatically unlock the switch assembly 3 when rotated to leave the locked position, making the unlocking operation smooth and ensuring the stability of the unlocked state.
[0049] See appendix Figure 7 In the above embodiment, the inner side of the tail cover 5 is provided with multiple positioning grooves 530. When the tail cover 5 is rotated to the locked or unlocked state of the switch assembly 3, or when the tail cover 5 is rotated to the exposed or hidden state of the charging interface 2, the pin 410 will fall into the positioning groove 530 under the elastic force of the spring 420. In this embodiment, the inner circumferential side of the tail cover 5 is provided with 6 positioning grooves 530. When in one of the three states of charging, ready, or locked, two pins 410 will fall into the corresponding positioning groove 530, generating a clear positioning sense, making it easy for the user to perceive the state switch to the correct position, making the operation feel clear and the state positioning accurate and reliable. In this embodiment, since the locking block 520 corresponds to the pin 410 in the locked state, two of the 6 positioning grooves 530 will be located on the two locking blocks 520 respectively.
[0050] See appendix Figure 2 In the above embodiment, the switch assembly 3 includes a switch 310 disposed inside the cylinder 1 and a keycap 320 disposed at the end face of the cylinder 1 and connected to the switch 310. The side of the keycap 320 is provided with a locking groove 321. When the pin 410 is engaged in the locking groove 321, the keycap 320 will be axially locked. In the embodiment, the mechanical force of the rotation of the tail cap 5 directly pushes the two pins 410 to engage in the locking groove 321 from two directions, axially locking the keycap 320, so that the keycap 320 cannot be axially pressed at all in the locked state, effectively preventing any accidental opening caused by accidental touch.
[0051] In an optional embodiment, the locking mechanism 4 includes a Hall element disposed inside the cylinder 1 and electrically connected to the switch assembly 3, and a magnetic element provided on the tail cover 5. The magnetic element cooperates with the Hall element to lock or unlock the switch assembly 3. In this embodiment, by adopting an electronically controlled locking scheme that uses a Hall element in cooperation with a magnetic element, physical contact can be achieved for switch locking and unlocking, which facilitates the improvement of the sealing and waterproof and dustproof performance of the tail structure, making the locking method more adaptable to harsh environments.
[0052] See appendix Figure 2In the above embodiment, an indicator light 6 is provided on the side of the cylinder 1, and a light hole 540 is provided on the side of the tail cover 5. When the charging interface 2 is exposed, the light hole 540 corresponds to the indicator light 6. In this embodiment, the indicator light 6 is located to the left of the charging port 110, and the light hole 540 is located to the left of the interface window 510. When the charging interface 2 is exposed, the light hole 540 corresponds to the indicator light 6, and the indicator light 6 can be observed through the light hole 540, making it easy for the user to intuitively understand the charging status. When the user rotates the tail cover 5 clockwise, it will switch to the ready state, at which time the interface window 510 corresponds to the indicator light 6, making it easy for the user to intuitively understand the lighting status.
[0053] See appendix Figure 8 and attached Figure 9 In the above embodiment, a limiting block 130 is provided on the side of the cylinder 1, and a limiting groove 550 is provided on the inner side of the tail cover 5. When the tail cover 5 rotates relative to the cylinder 1, the limiting block 130 will slide in the limiting groove 550. In this embodiment, the cooperation between the limiting block 130 of the cylinder 1 and the limiting groove 550 of the tail cover 5 ensures that the tail cover 5 can only rotate within the designed safe range. In this embodiment, the tail cover 5 is restricted to switching between three states: charging state, ready state, and locked state, making the state switching safe and reliable, and preventing excessive rotation from causing structural damage or state confusion.
[0054] See appendix Figure 1 This embodiment also provides a flashlight, including the aforementioned multi-state integrated flashlight tail structure, which realizes the flashlight has comprehensive advantages such as anti-accidental touch locking, hidden protection of charging interface, clear status indication, and convenient and smooth operation, which significantly improves the user experience of the whole device and makes the structure compact and reliable.
[0055] In summary, this embodiment provides a multi-state integrated flashlight tail structure and flashlight. By linking the rotatable tail cap 5, the locking mechanism 4, the charging port 110, and the interface window 510, a single rotation action synchronously controls the locked / unlocked state of the switch assembly 3 and the exposed / hidden state of the charging interface 2, facilitating quick switching between different functional states for the user. The physical locking of the switch assembly 3 is achieved through the cooperation between the movable pin 410 and the locking block 520 of the tail cap 5. A positioning groove 530 is provided on the inner side of the tail cap 5, and the pin 410 is placed into the groove by the spring 420, making it easy for the user to perceive the state switch. The precise limitation of the rotation angle of the tail cap 5 relative to the body 1 is achieved through the cooperation between the limiting block 130 of the tube body 1 and the limiting groove 550 of the tail cap 5. This embodiment achieves efficient integration of charging interface management, switch locking, and unlocking state control, enabling multi-state switching through a single operation, simplifying the operation logic, and improving the user experience.
[0056] The embodiments described above are merely one of the preferred embodiments of this utility model.
