[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] A flashlight with user - definable modes, as Figures 1 to 8 shown, includes: a barrel tail 1, a barrel - tail connector 2, a first PCB board 3, a second PCB board 4, a gear shaft 5, a gear 6 and a rotary dial 7; wherein, the barrel - tail connector is arranged above the barrel tail, the barrel - tail connector has a receiving cavity with an upward opening, and the first PCB board is arranged in the receiving cavity; a first switch is integrated on the first PCB board;

[0029] A first cavity is arranged inside the barrel tail, and a second cavity is arranged on the side wall of the barrel tail; the second PCB board is arranged in the first cavity; a through - hole is opened on the upper wall of the first cavity; a gear - position copper sheet 8 is arranged on the second PCB board at the position of the through - hole; a gear - position spring 9 and a gear - position bead 10 which are in mutual contact are arranged in the second cavity;

[0030] After a rotary spring 11 is sleeved on the gear shaft, the gear shaft is inserted into the through - hole in cooperation with the gear, and the gear shaft is in contact with the gear - position copper sheet; the upper part of the gear abuts against the barrel - tail connector;

[0031] The rotary dial is sleeved outside the barrel tail and the barrel - tail connector, and the inner wall of the rotary dial is in contact with the gear and the gear - position bead respectively;

[0032] When the rotary dial rotates, it serves as a second switch, that is, a dial switch.

[0033] The first switch and the second switch can respectively correspond to different states, so as to form multiple user - definable modes through the combination of the two, which is convenient for users to operate.

[0034] Further, it also includes a barrel tail connection cover 12 connected to the barrel tail connector; the first switch is preferably a two-stage push-button switch 22, and a silica gel cap 13 is sleeved on the two-stage push-button switch, which can enhance the waterproof effect.

[0035] Further, a button support 14 and a metal gasket 15 are arranged between the two-stage push-button switch and the silica gel cap; a waterproof ring 16 is arranged between the button support and the barrel tail connection cover.

[0036] Further, the flashlight also includes a barrel body 17 connected to the barrel tail; a negative electrode spring 18 is arranged at the bottom of the second PCB board, and the negative electrode spring is used for electrically connecting with the battery in the barrel body; a lock piece 19 is arranged between the barrel body and the barrel tail.

[0037] Further, an insulating pad 20 is arranged inside the lock piece; a waterproof ring 21 is arranged between the gear and the gear shaft.

[0038] The assembly sequence of the flashlight is as follows:

[0039] 1) After sleeving the waterproof ring 20 on the gear 6 and installing it into the barrel tail 1, then install the gear shaft 5 and insert the rotating elastic piece 11 into the gear for fixation.

[0040] 2) Install the second PCB board 4 into the barrel tail assembly, and use the lock piece 19 equipped with the insulating pad 20 to lock the second PCB board 4 in the barrel tail assembly.

[0041] 3) Install the gear position spring 9 and the gear position bead 10 on the barrel tail assembly, and then sleeve the rotating dial 7 and install it into the barrel tail connector 2, and use the threaded part equipped with the waterproof ring 16 to lock the barrel tail connector.

[0042] 4) Install the first PCB board 3 into the barrel tail assembly, solder the wire connection, and then sleeve the button support 14 and the metal gasket 15 on the switch.

[0043] 5) Lock the barrel tail connection cover equipped with the silica gel cap 13 and the waterproof ring 16 on the barrel tail assembly.

[0044] As Figure 4 shown, the flashlight with user-customizable modes includes, in terms of circuit composition: an LED, an LED driving circuit, a control circuit, a first switch S1 and a second switch S2;

[0045] Among them, the LED driving circuit, the first switch, and the second switch are respectively electrically connected to the control circuit; the LED driving circuit is electrically connected to the LED;

[0046] The first switch is used to define at least two usage states of the flashlight: the on state and the off state;

[0047] The second switch is used to define at least two working modes of the flashlight: the illumination mode and the setting mode;

[0048] When the flashlight is in the on state and the second switch is in the setting mode, trigger the first switch N times, and the LED will blink N times correspondingly to remind the user of the current working mode of the flashlight; when the second switch is in the lighting mode, the control circuit will set the flashlight to N user-defined modes; N is less than or equal to the preset upper limit value of the flashlight.

[0049] Taking the user-defined mode for restricting the number of brightness levels of the flashlight as an example, as Figure 4 shown, assume that the upper limit value of the user-defined mode supported by the flashlight is 4 (i.e., N = 4, and this preset upper limit value is determined by the factory setting). Each mode corresponds to a different number of brightness levels A. In mode 1, there is only one level A1 with a brightness of 3000 lumens. In mode 2, there are two levels A1 and A2 with brightnesses of 30 lumens and 1500 lumens respectively. And so on, in mode 4, there are five levels (i.e., M = 5, and this preset upper limit value is determined by the factory setting), which are A1 to A5, and their brightnesses are from 30 lumens to 3000 lumens respectively.

[0050] When in use, for a traditional flashlight, when the user selects the brightness, they must press from the low-brightness level to the highest-brightness level in sequence (assuming there are four brightness levels); if the user only wants the highest-brightness level, they must press four times to meet their needs. In this embodiment, after the user triggers the second switch twice, they enter mode 2, corresponding to two levels A1 and A2, and at the same time, the user only needs to press twice to meet their needs, thus greatly simplifying the operation steps.

[0051] When the user needs to use 5 brightness levels, when the flashlight is in the on state and the second switch is in the setting mode, press the first switch 4 times, and at the same time, the LED light blinks 4 times correspondingly. The user knows that the current custom mode is being set; when the user places the second switch in the lighting mode, the setting of 5 levels is completed. During use, when the second switch is in the lighting mode, the user triggers the first switch to achieve cyclic selection of 5 brightness levels.

[0052] It can be understood that the user-defined mode is not limited to restricting the number of brightness levels of the flashlight. As Figure 3 shown in the schematic diagram of the gear combination setting, in the setting mode, through a variety of preset gear combinations in the program, it is possible to set including but not limited to the number of levels, the lumen value of each level, the constant-on or blinking mode, etc. Among them, the number of modes is from 1 to m; A represents the level, and the number of levels is from 1 to iMAX; the corresponding level parameter below each level Ai is L, and its upper limit value is LMAX; m, iMAX, L, and LMAX are all determined by the factory setting. Thus, the user can achieve the purpose of using different level parameters in different scenarios through the custom mode.

[0053] Specifically, the first switch S1 and the second switch S2 are connected to the IO ports of the control circuit. By turning the switches on and off, the level signals of 0 and 1 are changed and fed back to the control circuit, and the control circuit drives and controls the LED.

[0054] The operation mode of the first switch includes at least defining different states according to the length of the circuit connection time, such as long press, short press or half press, etc., corresponding to different circuit on-off states respectively. For example, long pressing the first switch turns on the flashlight, and long pressing the first switch again enters the shutdown state. At the same time, combined with whether it is in the on state or the off state currently, and the working mode of the second switch, long pressing, short pressing or half pressing the first switch can also be defined as functions of gear adjustment and setting selection. It can be understood that the operation mode of the second switch can be the same as or different from that of the first switch. For example, in one implementation, the first switch uses a two-stage push-button switch, and the second switch uses a dial switch; or, both use two-stage or three-stage push-button switches, or both use dial switches, and it is specifically determined according to the hardware design of the flashlight.

[0055] When the second switch uses a dial switch, by rotating the dial switch, different contacts are connected to feed different signals back to the control circuit, thereby entering different working modes. The working modes include at least a lighting mode and a setting mode.

[0056] In the operation of the user setting a custom gear, refer to Figure 5 the flowchart shown. S2-3 represents the setting mode. When S2-3 is turned on, that is, the user starts to set the custom mode. The on-off states of S1-1 and S1-2 represent different operation signals when the user triggers the first switch S1. For example, when S1-1 is off and S1-2 is on, it is an operation signal, representing that the user long presses the first switch S1; when the user half presses the first switch S1, the two-stage push-button switch is between S1-1 and S1-2, and the operation signal transmitted to the control circuit board at this time is to switch gears in a certain user-defined mode.

[0057] Enter the user-defined setting mode through the operation of S2. In this mode, different gear combinations and brightness are selected through the operation of S1, and feedback is provided to the user through the on-off and brightness changes of the LED. When the storage space of the controller device program and the power of the LED are large enough, theoretically, enough gear brightness can be set to fully meet the user's usage requirements.

[0058] Further, when the second switch is in the lighting mode in the on state, or when the second switch is in the lighting mode in the off state, long press the first switch for a first preset time, and the flashlight starts to flash in a variable frequency. Touch the first switch lightly, and the flashlight turns off the variable frequency flash. The variable frequency flash is suitable for outdoor distress, signal sending and other purposes.

[0059] Further, the second switch is also used to define a third working mode of the flashlight: the locking mode. The locking mode is used to prevent accidental touch when turning on or off the flashlight. Specifically, in the powered-on state and when the second switch is in the locking mode, the flashlight will not be turned off due to accidental touch; when the first switch is long-pressed for a first preset time, the flashlight is restricted from responding to variable-frequency strobe; when the second switch leaves the locking mode, the locking is released; or, in the powered-off state and when the second switch is in the locking mode, the flashlight is restricted from entering the powered-on state; when the first switch is long-pressed for a first preset time, the flashlight is restricted from responding to variable-frequency strobe; when the second switch leaves the locking mode, the locking is released.

[0060] Further, the first switch and the second switch are also used to define the factory reset state of the flashlight; in the non-setting mode, when the first switch is long-pressed and the second switch is placed in the setting mode and maintained for a second preset time, the flashlight enters the factory reset state. Specifically, as Figure 5 shown, in the non-setting mode, that is, when S2-3 is not connected, press and hold the first switch S1-2, and at the same time turn the second switch S2 to the S2-3 position to connect. If the state of pressing the switch S1-2 is maintained for more than time t, the factory default state is restored. If the switch S1-2 or S2-3 is disconnected within time t, the operation ends and the factory default state restoration operation is not responded to.

[0061] The above is an elaboration of the flashlight with user-customizable modes of the present invention to help understand the present invention; however, the implementation manners of the present invention are not limited by the above embodiments. Any changes, modifications, substitutions, combinations, and simplifications made without departing from the principle of the present invention shall be equivalent replacement manners and are all included in the protection scope of the present invention.
