Description

Technical Field

[0001] The utility model relates to the field of flashlights, in particular to an integrated rotary key switch and a flashlight. Background Art

[0002] In existing products with rotary switches (including potentiometers, encoders, etc.), the rotary switch can rotate 360 degrees without starting and stopping functions, and it cannot well control the gear accuracy and angle range. At the same time, the existing structure has a separate rotary knob and a push switch, which are combined by two or more parts, which is not conducive to the waterproof and dustproof structure and is not convenient enough in operation. Summary of the Utility Model

[0003] To overcome the shortcomings of the prior art, the utility model provides an integrated rotary key switch and a flashlight.

[0004] An integrated rotary key switch includes a main body, a rotary knob pressing member, and an electrical component; wherein,

[0005] The electrical component is arranged inside the cavity of the main body;

[0006] The outer surface of the main body is provided with a recessed accommodation cavity, and the accommodation cavity is provided with a contact hole leading to the inside of the cavity and a first limiting protrusion;

[0007] The bottom of the rotary knob pressing member has an abutting portion passing through the contact hole and contacting the electrical component, and a second limiting protrusion for abutting against the first limiting protrusion;

[0008] The rotary knob pressing member is assembled in the accommodation cavity so that the first limiting protrusion abuts against the second limiting protrusion; when the rotary knob pressing member starts to rotate, the electrical component is triggered to enter the first working state; when the rotary knob pressing member is rotated until the second limiting protrusion abuts against the first limiting protrusion again, the electrical component enters the second working state.

[0009] A flashlight includes a barrel body and the integrated rotary key switch as described above.

[0010] In one implementation manner of the integrated rotary key switch and the flashlight provided by the utility model, the rotary knob pressing member can rotate in the accommodation cavity of the main body and is connected to the electrical component; in use, different working states of the electrical component are formed by the abutment of the first limiting protrusion and the second limiting protrusion, such as the starting state and the cut-off state corresponding to the dimming function, and the stepless dimming function can be corresponding during rotation. At the same time, combined with the pressing function of the rotary knob pressing member, more adjustment methods can be combined.

[0011] In another implementation, the rotary dial can rotate clockwise or counterclockwise on the main body. The key rod passes through and coincides with the D-shaped hole of the potentiometer. When the rotary dial rotates, it drives the key rod to drive the D-shaped hole of the potentiometer to rotate. Different rotation angles trigger different electrode positions of the potentiometer to achieve different focusing angle functions. At the same time, pressing the key head can drive the key rod to move downward, trigger the switch to change gears, and the spring can return the key assembly to its original position.

[0012] Compared with the prior art, this technical solution integrates two common operation methods and structures of rotary adjustment and pressing adjustment. By setting the first limit protrusion and the second limit protrusion, or the positioning rod and the second limit groove, the start and stop limits (i.e., the start and stop functions) during the rotary adjustment process are realized, which can well control the gear accuracy and angle range, and can simultaneously realize the rotation adjustment and key adjustment functions on one structural main body, which is not only convenient for users to operate, but also conducive to waterproof and dustproof.

[0025] Embodiment 1, an integrated rotary button switch, as Figures 1 to 4 shown, includes a body 1, a knob pressing member 6 and an electrical component; wherein, the electrical component is arranged inside the cavity of the body; an inwardly concave receiving cavity 14 is arranged on the outer surface of the body, a contact hole 15 leading to the inside of the cavity and a first limiting protrusion 16 are arranged in the receiving cavity; the bottom of the knob pressing member has an abutting portion 61 passing through the contact hole and contacting the electrical component, and a second limiting protrusion 62 for abutting against the first limiting protrusion; the knob pressing member is assembled in the receiving cavity, so that the first limiting protrusion abuts against the second limiting protrusion; when starting to rotate the knob pressing member, the electrical component is triggered to enter the first working state; when the knob pressing member is rotated until the second limiting protrusion abuts against the first limiting protrusion again, the electrical component enters the second working state.

[0026] Specifically, the positions and specific shapes of the first limiting protrusion and the second limiting protrusion are not specifically limited. By the abutment of the two limiting protrusions, the start-stop function can be realized, and at least two working states of the electrical component can be correspondingly realized. Further, before the knob pressing member is rotated until the second limiting protrusion abuts against the first limiting protrusion again, the electrical component also enters at least one third working state between the first working state and the second working state.

[0027] For example, in one implementation manner, the potentiometer is a composite potentiometer with start-stop and push-button switch functions. When the knob pressing member starts to rotate, the contact switch is turned on, and then rotation can realize stepless dimming. When the two limiting protrusions abut against each other, it is the cut-off position; when it is necessary to turn off the machine, when the knob is rotated back to the starting position, the contact switch is turned off, and the gear accuracy and angle range can be well regulated; at the same time, when the knob is pressed, the functions of shifting gears and changing modes can be realized.

[0028] Further, in terms of structure, the knob pressing member includes a rotary dial and a key rod; the rotary dial and the key rod are integrally formed or independently assembled; one end of the key rod corresponds to the abutting portion.

[0029] Further, the electrical component includes a PCB board 71, on which a potentiometer 72 is integrated; a spring 63 and a snap ring 64 are sleeved on the abutting portion and are connected to the potentiometer through a switch connecting member 8. Among them, the switch connecting member is arranged at the contact hole, the contact hole is cylindrical, and the two ends of the switch connecting member are respectively matched with the shapes of the potentiometer and the abutting portion.

[0030] Further, a waterproof ring 65 is also sleeved on the abutting portion, which can play a role in dust and water prevention.

[0031] Embodiment 2, an integrated rotary key switch, as Figures 5 to 9 shown, includes: a main body 1, a dial assembly, a key assembly and an electrical component; among them, the main body is a carrier for installing the dial assembly, the key assembly and the electrical component, and its specific structure is not limited.

[0032] The key assembly is used to realize the function of the key, and includes a key head 2, a key rod 21 and a spring 22; the lower end of the key head is connected to the key rod; the spring is sleeved on the key head and moves up and down with the key head; a boss 23 is arranged on the side of the key rod; the boss is used to limit the key rod to only move up and down in the rotary dial and not to move axially alone.

[0033] The dial assembly is used to realize the function of rotational adjustment, and includes a rotary dial 3 and a positioning rod 34; a first accommodation groove 31 recessed inward is arranged in the middle of the rotary dial, a first through hole 32 is arranged in the middle of the first accommodation groove, and a first limiting groove 33 corresponding to and matching the boss is arranged in the first through hole; the positioning rod is fixed on the back of the rotary dial;

[0034] The main body 1 has a second accommodation groove 11 recessed inward, a second through hole 12 is arranged in the middle of the second accommodation groove, and a second limiting groove 13 matching the positioning rod is also arranged on the second accommodation groove, and the second limiting groove is used to limit the movement range of the positioning rod;

[0035] The electrical component includes a potentiometer 4 and a switch 5, and the potentiometer is arranged above the switch; it can be understood that both the potentiometer and the switch are arranged on the PCB board.

[0036] The key assembly is assembled in the first accommodation groove of the rotary dial, the dial assembly is assembled in the second accommodation groove, the key rod sequentially passes through the first through hole, the second through hole, and the D-shaped hole of the potentiometer and then abuts against the switch, and the boss is snapped into the first limiting groove, and the positioning rod is snapped into the second limiting groove.

[0037] In use, different electrode positions of the potentiometer can be triggered by rotating the rotary dial to achieve different focusing angle functions, but not limited to this. At the same time, pressing the button head in the middle of the rotary dial can achieve the function of conventional switch switching.

[0038] Further, the button rod and the button head are fixed by threaded connection, or the button rod and the button head are integrally formed. That is, in terms of implementation, the button rod and the button head can be two independent structural parts or a single piece integrally formed.

[0039] Further, the first through hole extends upward and downward respectively to form a cylinder, and the first limiting groove is arranged on the inner wall of the cylinder; the button head is in a T shape, the lower end of the button head is clamped into the inner diameter of the cylinder, and the spring is sleeved on the outer periphery of the upper end of the cylinder. That is, the first through hole and the first accommodating groove form an annular structure, which is convenient for accommodating the button head and the spring, and makes the button assembly and the dial assembly fit more closely.

[0040] Further, the second limiting groove is distributed in an arc shape. The length and shape of the second limiting groove can be flexibly set, limited to the range of activities that can limit the positioning rod.

[0041] Further, the positioning rod is embedded in the back of the rotary dial, or the positioning rod and the back of the rotary dial are integrally formed. In terms of implementation, the positioning rod and the rotary dial can be two independent structural parts or a single piece integrally formed.
