[0003] In view of the above problems, this utility model is proposed to provide a tail cap and flashlight with a rotary switch that overcomes or at least partially solves the above problems.
[0004] In a first aspect, this utility model provides a tail cap with a rotary switch. The tail cap with the rotary switch is applied to a flashlight and includes a sleeve and a switch assembly connected to the sleeve. A negative spring is arranged inside the sleeve. The switch assembly includes a point switch, a switch base, a push cap, a return spring, a connecting sleeve, and a rotating ring. The point switch is arranged within the mounting space of the switch base. The push cap can be moved towards the point switch and extends into the mounting space through the end opening of the switch base, abutting against the contact of the point switch. The two ends of the return spring abut against the push cap and the switch base respectively, for causing the push cap to move away from the point switch. The connecting sleeve is sleeved on the outer periphery of the push cap, and the connecting sleeve and the push cap together form a constraint that prevents the push cap from rotating relative to the connecting sleeve. The front end of the connecting sleeve extends into the sleeve and is restricted from axial movement; the rotating ring is fitted around the outer periphery of the portion of the connecting sleeve located outside the sleeve and is fixedly connected to it; a positioning bead is provided at the front end of the connecting sleeve; the switch base has three positioning holes located on the same virtual ring that can cooperate with the positioning bead; a top block is formed on the outer side of the switch base; the front end of the button has a low platform, a middle platform, and a high platform formed circumferentially, with the distance between the low platform, the middle platform, the high platform and the front end of the button increasing sequentially; when the positioning bead extends into the corresponding positioning hole, the top block and the corresponding low platform, middle platform or high platform together constrain the maximum distance the button moves towards the point switch.
[0005] In one embodiment, an annular boss is formed on the inner sidewall of the sleeve, and a positioning boss adjacent to the annular boss is formed at the front end of the connecting sleeve. The front end of the connecting sleeve is located between the annular boss and the annular base of the switch seat.
[0006] In one embodiment, the push cap has a top post, which, when the push cap is moved toward the point switch, extends through the end opening of the switch base into the mounting space and abuts against the contact of the point switch.
[0007] In one embodiment, the outer peripheral wall of the button is formed with a key extending in a direction parallel to the virtual axis of the button, and the inner wall of the connecting sleeve is formed with a keyway that mates with the key.
[0008] In one embodiment, the front end of the rotating ring is fitted onto the end of the sleeve, and a sealing ring is provided between the two.
[0009] Secondly, this utility model provides a flashlight, which includes a lamp head assembly, a body, a battery, and a tail cap with a rotary switch as described in the first aspect.
[0010] This utility model embodiment of the flashlight achieves switching and positioning of power levels (constant light, locked, and intermittent light) by rotating a rotating ring, which can meet the diverse needs of users in different scenarios and is highly practical.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] The following description, with reference to the accompanying drawings, describes a flashlight according to an embodiment of the present invention.
[0028] See Figure 1 According to an embodiment of the present invention, a flashlight includes a lamp head assembly 1, a body 2, a battery, and a tail cap 3 containing a rotary switch. The lamp head assembly 1 may include LED beads, reflectors, etc. The two ends of the body 2 are respectively connected to the lamp head assembly 1 and the tail cap 3 containing the rotary switch, and the battery is arranged inside the body 2.
[0029] See now Figures 2 to 4 The tail cover 3 with a rotary switch includes a sleeve 4 and a switch assembly connected to the sleeve 4. A negative spring 5 is arranged inside the sleeve 4. The switch assembly includes a point switch 6, a switch base 7, a push cap 8, a return spring 9, a connecting sleeve 10, and a rotating ring 11.
[0030] When the contact of switch 6 is pressed, it can switch the flashlight circuit on and off. For example, when the contact of switch 6 is fully pressed and released, the flashlight circuit is connected and the LED light is lit; when the contact of switch 6 is fully pressed and released again, the flashlight circuit is disconnected and the LED light is turned off; when the contact of switch 6 is pressed halfway, the flashlight circuit is connected and the LED light is lit; when the contact of switch 6 is released, the flashlight circuit is disconnected and the LED light is turned off.
[0031] The point switch 6 is arranged within the mounting space of the switch base 7. The push cap 8 can be moved towards the point switch 6 and extends into the mounting space through the end opening of the switch base 7, abutting against the contact of the point switch 6. In this embodiment, the push cap 8 has a top post 12. When the push cap 8 is moved towards the point switch 6, the top post 12 can extend into the mounting space through the end opening of the switch base 7, abutting against the contact of the point switch 6.
[0032] The return spring 9 has two ends abutting against the button 8 and the switch base 7, respectively, to cause the button 8 to move away from the switch 6. That is, the button 8 is pressed and moves towards the switch 6. After the button 8 is released, the return spring 9 can cause the button 8 to move away from the switch 6 to reset. In this embodiment, the top post 12 extends into the inner hole of the return spring 9 to ensure that the return spring 9 maintains axial stability when it is stretched and contracted under force, and avoids skewing.
[0033] The connecting sleeve 10 is fitted around the outer periphery of the button cap 8, and the connecting sleeve 10 and the button cap 8 together form a constraint that prevents the button cap 8 from rotating relative to the connecting sleeve 10. See also Figure 5 and Figure 8 In this embodiment, the outer peripheral wall of the button cap 8 is formed with a key 13 extending in a direction parallel to the virtual axis of the button cap 8, and the inner wall of the connecting sleeve 10 is formed with a keyway 14 that mates with the key 13. The engagement of the key 13 and the keyway 14 prevents the button cap 8 from rotating relative to the connecting sleeve 10. The front end of the connecting sleeve 10 extends into the sleeve 4 and is restricted from axial movement. Now, let's return to the previous section. Figure 3 In this embodiment, an annular boss 15 is formed on the inner sidewall of the sleeve 4, and a positioning boss 16 adjacent to the annular boss 15 is formed at the front end of the connecting sleeve 10. The front end of the connecting sleeve 10 is located between the annular boss 15 and the annular base 17 of the switch seat 7. When the connecting sleeve 10 rotates relative to the sleeve 4, it can simultaneously drive the button 8 to rotate relative to the switch seat 7.
[0034] See now Figure 2 and Figure 3 The rotating ring 11 is sleeved on the outer periphery of the portion of the connecting sleeve 10 located outside the sleeve 4 and is fixedly connected to it. The rotating ring 11 drives the connecting sleeve 10 to rotate relative to the sleeve 4, thereby driving the button cap 8 to rotate relative to the switch base 7. In this embodiment, the front end of the rotating ring 11 is sleeved on the end of the sleeve 4, and a sealing ring is provided between the two. The end of the button cap 8 extends out of the end opening of the rotating ring 11.
[0035] See now Figure 3 , Figure 5 , Figure 6 , Figure 8 ,as well as Figure 9The front end of the connecting sleeve 10 is provided with a positioning bead 18. The switch base 7 has three positioning holes 19 located on the same virtual ring and capable of cooperating with the positioning bead 18. Specifically, in this embodiment, the positioning holes 19 are formed on the annular base 17. A top block 20 is formed on the outer side of the switch base 7, and the front end of the button cap 8 has a low platform 21, a middle platform 22, and a high platform 23 formed circumferentially. The distance between the low platform 21, the middle platform 22, and the high platform 23 and the front end of the button cap 8 increases sequentially. When the positioning bead 18 extends into the corresponding positioning hole 19, the top block 20 and the corresponding low platform 21, middle platform 22, or high platform 23 together constrain the maximum distance that the button cap 8 moves towards the point switch 6.
[0036] Reference Figure 9 From a perspective, the positioning hole 19 located in the lower left corner is defined as the first positioning hole, the positioning hole 19 located on the upper side is defined as the third positioning hole, and the positioning hole 19 located between the first and third positioning holes is defined as the second positioning hole. When the rotating ring 11 is rotated so that the positioning bead 18 of the connecting sleeve 10 extends into the first positioning hole (constant lighting mode), the top block 20 and the low platform 21 are in relative positions. Pressing the button cap 8 can fully press the contact of the point switch 6, connecting the flashlight circuit and illuminating the LED (constant lighting). After releasing the button cap 8, pressing the button cap 8 again fully presses the contact of the point switch 6 and then releasing it disconnects the flashlight circuit and extinguishes the LED.
[0037] When the rotating ring 11 is rotated so that the positioning bead 18 of the connecting sleeve 10 extends into the second positioning hole (locking position), the top block 20 and the high platform 23 are in relative positions. Since the distance between the top block 20 and the high platform 23 is relatively close, pressing the button 8 only moves the button 8 a small distance toward the point switch 6. The button 8 cannot contact the contact point of the point switch 6, thus "locking" the button 8 and preventing the flashlight from being turned on by accident during carrying or storage. This protects the battery power and prevents accidental lighting or accidental extinguishing.
[0038] When the rotating ring 11 is rotated so that the positioning bead 18 of the connecting sleeve 10 extends into the third positioning hole (instant lighting mode), the top block 20 and the middle platform 22 are in relative positions. When the button cap 8 is pressed until the contact of the moment switch 6 is pressed halfway, the middle platform 22 abuts against the top block 20, preventing the button cap 8 from moving further towards the moment switch 6. Therefore, pressing the button cap 8 can only press the contact of the moment switch 6 halfway. When the contact of the moment switch 6 is pressed halfway, the flashlight circuit is connected, and the LED light shines (instant lighting). When the button cap 8 is released, the flashlight circuit is disconnected, and the LED light goes out. This is suitable for scenarios requiring short-term lighting, such as viewing a local area or searching for items, allowing users to flexibly control the lighting time and save power.
[0039] See now Figure 8 and Figure 10 The outer peripheral wall of the front end of the connecting sleeve 10 is concave inward to form an arc-shaped limiting area 24. The inner wall of the sleeve 4 is convex to form a limiting part 25 that extends into the arc-shaped limiting area 24. When the connecting sleeve 10 rotates relative to the sleeve 4, the limiting part 25 moves within the arc-shaped limiting area 24 until it abuts against the end walls of the arc-shaped limiting area 24, thereby limiting the angle of rotation of the connecting sleeve 10 relative to the sleeve 4.
[0040] In this embodiment, the flashlight switches and positions its modes (constant light, locked mode, and intermittent light) by rotating a ring, which can meet the diverse needs of users in different scenarios and is highly practical.
