Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, in particular to a double-travel switch. Background Art

[0002] The existing dual-stroke switch uses the stroke setting of the touch switch itself to generate different resistances when pressed, which further leads to different pressing times, so as to achieve the dual-stroke effects of half press and full press, and further realize two different functional requirements.

[0003] However, the existing two-stroke switch is usually a micro-touch switch, which has a small stroke (0.2-0.5 mm), and the hand feeling produced when pressed is not obvious. It is difficult for the operator to feel the difference between half-press and full-press when using it, which easily leads to functional failure. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] like Figure 1As shown, this embodiment provides a double-travel switch, which includes:

[0028] A control unit 1, which includes components such as a PCB board;

[0029] A first switch 2 and a second switch 3, both of which are mounted on the control unit 1. In this embodiment, one or both of the first switch 2 and the second switch 3 are touch switches, and the first switch 2 and the second switch 3 have the same model and specification;

[0030] A triggering part 5, which has a first contact 51 in contact with the first switch 2, a second contact 52 in contact with the second switch 3, and a fulcrum O, and a distance L1 from the fulcrum O of the triggering part 5 to the first contact 51 is not equal to a distance L2 from the fulcrum O of the triggering part 5 to the second contact 52;

[0031] and a pressing portion 6 connected to the trigger portion 5, and when the pressing portion 6 is pressed, different pressures are applied to the first switch 2 and the second switch 3 through the trigger portion 5, so that one of the first switch 2 and the second switch 3 is electrically connected to the control unit 1 first to be triggered first, and the other of the first switch 2 and the second switch 3 is electrically connected to the control unit 1 later to be triggered later, so as to achieve a double-stroke effect of half pressing and full pressing.

[0032] For example, in this embodiment, the distance L1 from the fulcrum O of the trigger portion 5 to the first contact 51 is greater than the distance L2 from the fulcrum O of the trigger portion 5 to the second contact 52, and the first contact 51 and the second contact 52 are respectively located on the vertical center axes of the first switch 2 and the second switch 3;

[0033] When the pressing portion 6 is pressed to the first stroke (such as 1 mm), the pressure it receives is transmitted to the trigger portion 5, and then transmitted to the first switch 2 and the second switch 3 through the first contact 51 and the second contact 52 respectively. The pressure received by the first switch 2 is F1, and the pressure received by the second switch 3 is F2. It can be seen from the torque formula F1*L1=F2*L2 that since L1>L2, F1<F2, that is, the pressure received by the second switch 3 is larger. In this case, the second switch 3 is triggered first, and the corresponding function is further executed through the control unit 1. When the pressing portion 6 continues to be pressed to the second stroke (such as 2 mm), the first switch 2 is triggered, thereby achieving the double stroke effects of half pressing and full pressing.

[0034] On the contrary, when the distance L1 from the fulcrum O of the trigger part 5 to the first contact 51 is smaller than the distance L2 from the fulcrum O of the trigger part 5 to the second contact 52 , the first switch 2 is triggered first and the second switch 3 is triggered later.

[0035] Therefore, the double-stroke switch in this embodiment can disperse the pressure exerted on the pressing portion 6 to the first contact 51 and the second contact 52, and make the first switch 2 and the second switch 3 exert different pressures, so that the first switch 2 and the second switch 3 are triggered successively, and its operating stroke is large (can reach 1 to 2 mm), and the operating feel is obvious and easy to operate, and the double-stroke effect of half press and full press can be achieved.

[0036] Embodiment 2:

[0037] The difference between this embodiment and embodiment 1 is that the double-travel switch further includes:

[0038] The inner bracket 4 is connected to the control unit 1 and has an inner accommodating space 41 and an upper opening 42, and the first switch 2, the second switch 3, and the trigger part 5 are all located in the inner accommodating space 41; at the same time, the bottom of the pressing part 6 extends from the upper opening 42 into the inner accommodating space 41 and is gap-matched with the inner bracket 4;

[0039] An outer bracket 7, which is sleeved on the periphery of the inner bracket 4 and connected to the inner bracket 4 and / or the control unit 1; in this embodiment, the outer bracket 7 abuts against the outer wall surface of the inner bracket 4;

[0040] A first isolation portion 8 is sleeved on the periphery of the inner bracket 4, and the upper portion is connected to the pressing portion 6, and the lower portion is connected to the outer bracket 7, so as to isolate the upper opening 42 of the inner bracket 4 from the external environment;

[0041] And a second isolating portion 9 is sleeved on the periphery of the first isolating portion 8 and connected to the outer bracket 7 .

[0042] In this embodiment, the first isolating portion 8 and the second isolating portion 9 are both made of waterproof materials, such as rubber, etc., thereby achieving double isolation through the two isolating portions to achieve better waterproof and dustproof effects.

[0043] Embodiment 3:

[0044] The only difference between this embodiment and Embodiment 1 or 2 is that a recessed portion 61 is formed on the pressing portion 6, and the recessed portion 61 may be an annular structure, and the upper portion of the first isolating portion 8 is accommodated in the recessed portion 61, thereby preventing the first isolating portion 8 from being separated from the pressing portion 6.

[0045] To sum up, the double-stroke switch of the utility model can disperse the pressure exerted on the pressing part to the first contact and the second contact, so that the first switch and the second switch are further triggered successively. The operation stroke is large, and the operation feel is obvious and easy to operate. The double-stroke effect of half press and full press can be achieved. At the same time, double isolation is achieved through two isolation parts to achieve better waterproof and dustproof effects.
