Detailed Description

The following describes the structural and operational principles of the present invention in detail with reference to the accompanying drawings:

as shown in fig. 1 to 6, the present invention provides a bidirectional switch device that can be turned on or off in one direction (e.g., forward or clockwise) and can be turned on or off in the other direction (e.g., reverse or counterclockwise). The utility model discloses two-way switch device includes a carrier 1, an at least touch switch 2, one make the actuating lever 3 and an at least rotation piece 4, and the preferred still includes a swing reset assembly 5 and a swing locating component 6.

The carrier 1 can be various articles for carrying various components, such as a plate or a block not shown in the drawings, or a housing as shown in the drawings, which is taken as an example for illustration in the present embodiment. The carrier 1 is provided with a rotating shaft 13, the rotating shaft 13 can rotate back and forth relative to the carrier 1, and the rotating shaft 13 has an inner section and an outer section (no reference symbol) respectively located inside and outside the carrier 1.

The touch switch 2 is fixedly arranged in the carrier 1 and has a touch part 221. In detail, as shown in fig. 2 and 5, the touch switch 2 includes a switch body 21 and a movable arm 22, and the movable arm 22 is pivoted to the switch body 21 and can move relative to the switch body 21 after being moved. The driven arm 22 is further provided with the touch portion 221, and the touch portion 221 defines a first position before touch (see fig. 5) and a second position after touch (see fig. 6).

The actuating rod 3 is fixed on the outer section of the rotating shaft 13, so that the rotating shaft 13 can be driven to deflect by a plurality of deflection angles by operating the actuating rod 3. The yaw includes positive and negative yaw, and these yaw angles include a positive yaw angle + A as shown in FIG. 9, a negative yaw angle-A as shown in FIG. 6, and a zero yaw angle (not labeled, the zero yaw angle being between the positive yaw angle + A and the negative yaw angle-A) as shown in FIG. 5.

The rotating member 4 is fixedly disposed at an inner section of the rotating shaft 13, so that the rotating member 4 can swing (including forward swing and reverse swing) along with the rotating shaft 13, and the rotating member 4 and the touch switch 2 are arranged side by side as shown in fig. 2. As shown in fig. 5, the rotating member 4 has two abutting portions 411 and a recessed portion 412 recessed with respect to the two abutting portions 411.

The rotating member 4 can be any object capable of deflecting along with the rotating shaft 13 and interacting with the touch portion 221, such as a cam not shown in the drawings, or a rotating disc disposed on the rotating shaft 13 as shown in the drawings, which is exemplified by a rotating disc having a periphery 41 and defining a radial direction (not labeled with reference numbers). As shown in fig. 5, two different positions of the peripheral edge 41 are the two abutting portions 411, and the recessed portion 412 is formed between the two abutting portions 411 and is recessed from the peripheral edge 41 along the radial direction; the movable arm 22 of the trigger switch 2 is provided with the trigger 221, and the trigger 221 is accommodated in the recess 412 and located at a first position before triggering (as shown in fig. 5).

It should be noted that the first position refers to a position where the touch portion 221 extends into the recess 412 completely or partially beyond the peripheral edge 41; the second position is a position where the touch portion 221 is withdrawn from the recess 412 in a reverse direction and abuts against the abutting portion 411.

Therefore, when the user does not operate the actuating rod 3, the touch portion 221 is still located in the recess 412 and is not touched, so that the touch switch 2 is not triggered, and the rotating shaft 13 has a zero deflection angle (as shown in fig. 5); when it is necessary to control a power-ON loop (not shown) to be ON or OFF by using the touch switch 2, as long as the user operates the actuating rod 3 to drive the rotating shaft 13 and the rotating member 4 to reversely deflect, the rotating member 4 abuts against the touch portion 221 by one of the abutting portions 411, so that the touch portion 221 is forced to move to the second position (shown in fig. 6) to touch and trigger the touch switch 2, and the rotating shaft 13 at this time is at a negative deflection angle-a; alternatively, the actuating rod 3 can be operated to deflect in the positive direction, so that the rotating member 4 abuts against the touch portion 221 through the other abutting portion 411, and the touch portion 221 is forced to move to the second position (as shown in fig. 9) to touch and trigger the touch switch 2, and the rotating shaft 13 is at the positive deflection angle + a. And the touch switch 2 can control the power-ON loop to be ON or OFF after being triggered.

The swing reset assembly 5 is used to control the rotating member 4 to automatically reset to receive the touching portion 221 by the recessed portion 412, i.e. to control the rotating shaft 13 to reset from the positive swing angle + a (or the negative swing angle-a) to the zero swing angle. In other embodiments not shown in the drawings, when the present invention does not have the swing reset assembly 5, the user can reset by applying a reverse force to the actuating rod 3.

The swing return element 5 includes a fixed element 51, a movable element 52, and a swing return spring 53 disposed between the fixed element 51 and the movable element 52. Wherein, the fixing member 51 is fixed in the carrier 1 and has a fixing arm 511; the movable element 52 is fixed on the rotating shaft 13 and has a movable arm 521, and the movable element 52 can swing relative to the fixed element 51 along with the rotating shaft 13; the swing return spring 53 has two force receiving portions 531,532, the fixed arm 511 limits one of the force receiving portions 531 (or 532), and the swing return spring 53 applies force to push the other force receiving portion 532 (or 531) through the movable arm 521 to generate elastic restoring force. In short, when the rotating shaft 13 is operated to swing reversely, as shown in fig. 6, the fixed arm 511 restricts the force receiving portion 531, and the movable arm 52 applies force to push the force receiving portion 532; when the rotating shaft 13 is operated to swing in the normal direction, as shown in fig. 9, the fixed arm 511 restricts the force receiving portion 532, and the movable arm 52 applies a force to push the force receiving portion 531.

Preferably, the fixed element 51, the movable element 52 and the swing return spring 53 are coaxially sleeved on the rotating shaft 13 and respectively have a fixed arm 511, a movable arm 521 and two force-receiving

portions

531 and 532 at eccentric positions; the swing return spring 53 may be a torsion spring and is movably clamped between the fixed member 51 and the movable member 52, a space S (see fig. 5) is formed between the two adjacent force receiving portions 531,532, and the fixed arm 511 and the movable arm 521 are both located in the space S and respectively overlap the two force receiving portions 531,532 (the fixed arm 511 and the movable arm 521 protrude toward each other and overlap each other).

The swing positioning assembly 6 is used for positioning the rotating shaft 13 at the above-mentioned each deflection angle respectively. The swing positioning assembly 6 includes a positioning member 61 and a brake arm 62, and preferably also includes a positioning return spring 63.

As shown in fig. 1, fig. 2 and fig. 7, the positioning element 61 is fixed at the outer section of the rotating shaft 13 and can swing along with the rotating shaft 13, the present invention does not limit what kind of the positioning element 61 is, and the rotating disc is exemplified in the present embodiment, and the rotating disc also has a periphery 610 and defines a radial direction (no reference symbol). Two different positions of the peripheral edge 610 have two positioning recesses 612,613 recessed from the peripheral edge 610 in the radial direction, and a positioning protrusion 611 protruding from the two positioning recesses 612,613 is formed between the two positioning recesses 612,613 spaced apart from each other.

The stopper arm 62 is pivoted to the outer wall of the carrier 1 such that the stopper arm 62 and the positioning member 61 are arranged side by side with each other as shown in fig. 8. The stopper arm 62 has a protrusion 621 for abutting against and positioning on the positioning protrusion 611, and the protrusion 621 may be rod-shaped and has a rod peripheral wall. The abutting edge of the positioning protrusion 611 for abutting and positioning the protrusion 621 is V-shaped, that is, the abutting edge has two slopes declining relatively, and the protrusion 621 is abutted and positioned at the connection position between the two slopes. As for the positioning return spring 63 for controlling the return of the stopper arm 62, it is specifically made that the positioning return spring 63 is connected between one end of the stopper arm 62 and the outer wall of the carrier 1.

In this way, when the rotating shaft 13 is at the zero deflection angle, as shown in fig. 2, the convex body 621 abuts between the two slopes of the positioning convex part 611 to be positioned; when the rotating shaft 13 is at the negative deflection angle-a, as shown in fig. 7, the positioning element 61 reversely deflects along the rotating shaft 13, so that the abutting edge of the positioning protrusion 611 slides along the rod peripheral wall of the protrusion 621, and the positioning element 61 changes the positioning recess 612 to correspond to the protrusion 621, and at this time, the elastic restoring force of the positioning restoring spring 63 drives the protrusion 621 to automatically snap into the positioning recess 612 for positioning; when the rotating shaft 13 is at the positive deflection angle + a, as shown in fig. 10, the positioning member 61 is deflected in the positive direction along with the rotating shaft 13, so that the convex body 621 is automatically locked in the positioning concave portion 613 for positioning.

As shown in fig. 1 and fig. 2, the other end of the braking arm 62 is a pivot end 622, the braking arm 62 is pivoted to the carrier 1 by the pivot end 622, and the pivot end 622 is further connected to a release handle 64, the release handle 64 can drive the braking arm 62 to swing around the pivot end 622, so that the positioning state can be released by operating the release handle 64.

When any one of the positioning recesses 612,613 of the positioning member 61 is locked by the convex body 621 to be in the positioning state, as shown in fig. 8, the user can move the release handle 64 to make the convex body 621 swing together with the brake arm 62 to exit from the positioning recesses 612, 613. At this time, since the positioning member 61 is no longer positioned by the convex body 621, the rotation shaft 13 is automatically rotated to the zero-runout angle shown in fig. 2 by the elastic restoring force of the swing return spring 53, and the positioning convex portion 611 is positioned at the zero-runout angle by being abutted by the convex body 621 again.

In addition, as shown in fig. 1 and fig. 2, the touch switch 2 and the rotating member 4 may also be provided in two configurations, two touch switches 2 are arranged side by side or stacked on each other, two rotating members 4 are also arranged side by side or stacked on each other, and the touch portion 221 of each touch switch 2 is respectively accommodated in the recess 412 of each rotating member 4; therefore, when one group of touch control fails, the other group can be used for touch control, so that the touch control is ensured to be carried out smoothly. As shown in fig. 2, 5 and 6, the touch portion 221 of the touch switch 2 may also be a roller, and the roller rolls rather than fixedly rubs against the periphery 41 of the rotating member 4, so as to ensure that the driven arm 22 of the touch switch 2 will not be actuated or failed by the friction shock. As shown in fig. 1 and 5, a pull rope R may be further connected to an end of the actuating rod 3 away from the rotating shaft 13, and a user may pull a right segment (or a left segment) of the pull rope R to control the actuating rod 3 to perform reverse deflection (or forward deflection) as shown in fig. 6 (or as shown in fig. 9); in order to increase the interference strength of the pull rope R on the actuating rod 3, at least two rope rings 31 may be further disposed at the end of the actuating rod 3, so that the interference strength of the pull rope R on the actuating rod 3 can be increased by winding the pull rope R around each rope ring 31, thereby facilitating the forward and reverse deflection of the actuating rod 3 by pulling the pull rope R. As shown in fig. 1 to 4, the carrier 1 in the form of a housing may include a first housing 11 and a second housing 12 combined with each other, and the rotating shaft 13, the tact switch 2, the fixing member 51 and the brake arm 62 are disposed on the first housing 11.

It should be noted that the rotating member 4, the moving member 52, the swing return spring 53 and the fixing member 51 can be all coaxially sleeved on the inner section of the rotating shaft 13, and the positioning member 61 and the actuating rod 3 can be all coaxially fixed on the outer section of the rotating shaft 13, but the present invention is not limited to these arrangements. The trigger switch 2 is arranged in a radial direction and the rotary member 4 are arranged side by side with each other, and the brake arm 62 is also arranged in a radial direction and the positioning member 61 are arranged side by side with each other.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
