Referring to fig. 1-3, an embodiment of the utility model provides a small angle switch including a switch structure and a conductive structure. The switch structure can change the state of the conductive structure, so that the conductive structure is connected or short-circuited, and the switch is switched on or off.

Referring to fig. 2-3, an embodiment of the present invention provides a switch structure, which includes a function element 200, a transition element 300 and a button 100. Wherein, the transition piece 300 is rotatably disposed on the functional piece 200. Transition piece 300 includes a shank 310. The rod body 310 has both ends along its length. The button 100 may abut against either end of the lever 310. When the switch structure is used, the button 100 can be manually or mechanically touched to enable the button 100 to rotate relative to the functional piece 200, and in the rotating process of the button 100, the corresponding ends of the button 100 and the rod body 310 are abutted, so that the transition piece 300 is driven to rotate relative to the functional piece 200, the state of the transition piece 300 is changed, and the state of the switch structure is further changed.

As shown in fig. 2 and 4, the functional element 200 has a first surface 201 and a second surface 202 disposed opposite to each other. The distance from the first surface 201 to the second surface 202 may be defined as the length of the functional element 200. When the switch structure is installed, the length direction of the functional element 200 is identical to the length direction of the rod body 310. The length of the rod body 310 is greater than the length of the functional element 200. At least one end of the rod body 310 protrudes from the first surface 201 or the second surface 202.

The length through setting up the body of rod 310 is greater than the length of function piece 200 for when button 100 atress drove the body of rod 310 and rotates, button 100 rotated with the small-angle and can drive the body of rod 310 and rotate, thereby changed transition 300's state. In some embodiments, the length of the rod 310 is greater than the length of the functional element 200, and the button 100 can be rotated within 1 ° to change the state of the transition element 300. Compared with some comparative examples in which the length of the rod 310 is less than that of the functional element 200, the button of the switch structure in the comparative examples needs to be rotated by 6 ° to change the state of the transition element, so as to change the on/off of the switch.

Therefore, by setting the length of the rod 310 to be greater than the length of the function element 200, the displacement distance of the end of the rod 310 can be increased by increasing the rotation radius of the rod 310 (i.e. the distance between the end of the rod 310 and the rotational connection between the rod 310 and the function element 200), so that the state of the transition element 300 can be changed by rotating the button 100 at a small angle.

As shown in fig. 2 to 5, in some embodiments, the rod 310 of the transition piece 300 is provided with an abutting portion 311 at each end along the length direction thereof, and the abutting portion 311 may abut against the button 100. The abutting portion 311 is disposed on a side of the lever 310 close to the button 100. In some embodiments, the abutment 311 protrudes from the rod 310. The surface of the abutting portion 311 abutting against the button 100 may be a flat surface or a curved surface. The surface of the abutting portion 311 abutting the button 100 protrudes from the surface of the functional element 200 near the button 100 so that the button 100 abuts against the abutting portion 311.

In the embodiment shown in fig. 2-5, the abutting surface of the abutting portion 311 and the button 100 is a plane, and such an arrangement can increase the abutting area of the abutting portion 311 and the button 100, so that when the button 100 is pressed, the button 100 drives the abutting portion 311 to move, so as to drive the transition piece 300 to move.

In some embodiments, an abutment 311 is disposed at one end of the rod 310. In other embodiments, a plurality of abutments 311 may be provided at one end of the rod 310. The abutting portions 311 are provided at intervals.

Since the length of the rod 310 is greater than that of the functional element 200, at least one end of the rod 310 protrudes from the first surface 201 or the second surface 202. For example, as shown in fig. 2-5, in some embodiments, two ends of the rod 310 protrude from the first surface 201 and the second surface 202, respectively. For another example, in other embodiments, one end of the rod 310 protrudes from the first surface 201, and the other end of the rod 310 is flush with the second surface 202 or is located between the second surface 202 and the first surface 201. For another example, in some other embodiments, one end of the rod 310 protrudes from the second surface 202, and the other end of the rod 310 is flush with the second surface 202 or is located between the first surface 201 and the second surface 202.

In the embodiment shown in fig. 2-5, two ends of the rod 310 protrude from the first surface 201 and the second surface 202, respectively. That is to say, the first surface 201 and the second surface 202 of the functional element 200 are both provided with a protruding groove 240, and the extending direction of the protruding groove 240 is the same as the length direction of the rod body 310. The protruding slot 240 may receive a portion of the shank 310.

The length of the rod 310 protruding from the first surface 201 is the same as the length of the rod 310 protruding from the second surface 202. Such an arrangement may allow the button 100 to be rotated through a small angle when switched between the open and closed positions.

In some embodiments, as shown in fig. 5 and fig. 6, a position-avoiding notch 312 is disposed in the middle of the rod 310, and the position-avoiding notch 312 is disposed so that the rod 310 can reduce collision with the functional element 200 during rotation, thereby improving the service life of the small-angle switch.

As shown in fig. 2, 4, 6, and 7, in some embodiments, the transition piece 300 is provided with a rotating portion 320, and the rotating portion 320 may be movably connected with the functional piece 200. In some of these embodiments, the functional element 200 is provided with a connection hole 220. The rotating portion 320 is inserted into the connection hole 220. As shown in fig. 6 and 7, the rotating portion 320 includes a first position-limiting surface 322 and a second position-limiting surface 323. The first position-limiting surface 322 or the second position-limiting surface 323 can abut against the corresponding position of the hole wall of the connecting hole 220. For example, when the button 100 drives the transition piece 300 to move to the first position, the first position-limiting surface 322 abuts against the corresponding hole wall, and a gap is formed between the second position-limiting surface 323 and the hole wall of the connection hole 220. When the button 100 drives the transition piece 300 to move to the second position, the second limiting surface 323 abuts against the corresponding hole wall, and a gap is formed between the first limiting surface 322 and the hole wall of the connecting hole 220.

As shown in fig. 6 and 7, in some embodiments, one side of the first position-limiting surface 322 is connected to one side of the second position-limiting surface 323, and the other side of the first position-limiting surface 322 and the other side of the second position-limiting surface 323 are connected to two sides of the arc-shaped surface 324. The arc face 324 is spaced apart from the wall of the connection hole 220. The arc-shaped surface 324 can reduce friction between the sidewall of the rotating part 320 and the hole wall of the connecting hole 220 when the rotating part 320 rotates relative to the functional element 200. In the embodiment shown in fig. 6 and 7, the cross-sectional shape of the rotating portion 320 is a sector or a sector-like shape. Due to the arrangement, when the rotating part 320 is movably connected with the functional part 200, the connecting effect is good, the rotating process is smooth, the rotating part 320 cannot excessively rotate, and the probability of damage to the transition part 300 caused by rotation is reduced.

In some embodiments, the rotating portion 320 may be integrally formed with the rod 310, and the rotating portion 320 may also be separately disposed from and connected to the rod 310. In the embodiment shown in fig. 6, the number of the rotating portions 320 is two. The two rotating parts 320 are respectively disposed at both sides of the middle of the rod body 310. The rotating portion 320 is fixedly connected to the rod 310, and the connecting manner may be an integral forming. Correspondingly, as shown in fig. 7 and 8, the functional element 200 is provided with two connecting holes 220, and the two connecting holes 220 are movably connected with the two rotating parts 320 respectively.

As shown in fig. 7, the rotating portion 320 has a rotating center 321, and the rotating portion 320 can rotate along the rotating center 321, so as to rotate the transition piece 300 as a whole. Here, the rotation center 321 may be located inside the rotation portion 320 or may be located outside the rotation portion 320. For example, in some embodiments, the rotating portion 320 is a solid, and the center of rotation 321 may be located at the center of rotation of the rotating portion 320. For another example, in other embodiments, the rotating portion 320 is a hollow-out middle portion, and the rotation center 321 may be located at a rotation center of the hollow-out middle portion.

In some embodiments, the distance d (labeled in FIG. 3) between the center of rotation 321 and the surface of the button 100 away from the shaft 310 is no greater than 4 mm. For example, in one embodiment, the distance between the center of rotation 321 and the surface of the button 100 away from the shaft 310 is 3.4 mm. Based on the fact that the length of the rod body 310 is greater than that of the functional element 200, the distance between the rotation center 321 and the button 100 can be shortened to be within 4 mm. The above arrangement allows a switch having a small thickness of the button 100 to be obtained, thereby satisfying the consumer's demand for the switch.

As shown in fig. 2, 3, and 6, in some embodiments, transition piece 300 further includes a connection portion 330. The connecting portion 330 is connected to the middle portion of the rod body 310. The extending direction of the connecting portion 330 is at an angle with the length direction of the rod 310, for example, the extending direction of the connecting portion 330 is perpendicular to the length direction of the rod 310. The connecting portion 330 may be connected to the conductive component 600 of the small-angle switch, such that when the button 100 rotates the transition piece 300, the connecting portion 330 may cause the conductive component 600 to change states, thereby causing the small-angle switch to be turned on or off.

In some embodiments, referring to fig. 2 and 3, the connecting portion 330 is provided with a receiving hole 331, and the receiving hole 331 can receive the elastic member 700. The elastic member 700 may be an elastic material such as a spring. In a low angle switch, the conductive assembly 600 includes a paddle 620, a movable contact 610, and a stationary contact 630. The pick 620 has two projections spaced apart, one projection provided with the movable contact 610 and the other projection insertable into the spring so as to be inserted into the connection part 330. When the button 100 is pressed, the button 100 drives the rod 310 to rotate, the rod 310 drives the connecting portion 330 to rotate when rotating, and the connecting portion 330 drives the poking piece 620 to rotate when rotating, so that the movable contact 610 moves. When the movable contact 610 abuts the stationary contact 630, the conductive assembly 600 is energized, and the small angle switch is in a connected state. When the movable contact 610 is separated from the stationary contact 630, the conductive assembly 600 is not energized, and the small angle switch is in an open state.

In some embodiments, the gap between the elastic member 700 and the connection hole 220 may be increased by a certain amount, so as to improve the transmission compensation, i.e. the transmission compensation when the button 100 drives the connection part 330 of the transition piece 300 to rotate.

As shown in fig. 1 and 2, in some embodiments, in order to facilitate installation of the conductive assembly 600, the switch may further be provided with a housing 500, and the housing 500 may be connected with the functional element 200 or the fixing frame 400. The connection mode can be fixed connection or detachable connection, such as clamping connection, screw connection and the like.

In the embodiment shown in fig. 2-8, the transition piece 300 includes a rod body 310, a rotating portion 320, and a connecting portion 330. The length direction of the rod 310 is perpendicular to the extending direction of the connecting portion 330, and the rod 310 and the connecting portion 330 form a T-like shape. The number of the rotating portions 320 is two, and the two rotating portions 320 are disposed at an interval on one side of the rod body 310 away from the connecting portion 330. One of the rotating parts 320 is aligned with the extending direction of the connecting part 330, and the other rotating part 320 is disposed at a position parallel to and not coincident with the extending direction of the connecting part 330. Such an arrangement allows for the installation of additional components within the functional element 200 after the transition piece 300 is installed with the functional element 200, thereby expanding the functionality of the switch.

In some embodiments, the button 100 may be rotatably coupled to the function 200. In other embodiments, such as those shown in fig. 1-4, the switch structure may also be provided with a mounting bracket 400. The button 100 is rotatably connected to the fixing frame 400, and the fixing frame 400 is connected to the functional element 200. The provision of the holder 400 may facilitate the installation of the button 100.

The following description will be given taking as an example a mode in which the push button 100 is rotatably connected to the holder 400.

In some embodiments, as shown in fig. 9, the button 100 is provided with a first connection structure 110. As shown in fig. 2, 4 and 10, the fixing frame 400 is provided with a second connecting structure 430. The first connecting structure 110 is rotatably connected to the second connecting structure 430.

In some embodiments, as shown in fig. 9, the first connecting structure 110 may be a tab provided with a through hole, and a side of the through hole away from the button 100 is provided with a notch, so that the first connecting structure 110 is shaped like crab pincer. As shown in fig. 10, the second connecting structure 430 is a boss. When the installation is carried out, the bulge part is clamped into the through hole through the notch. The size of the notch is slightly smaller than the bulge, so that the bulge is not easy to separate from the through hole. In other embodiments, the first connecting structure may be a protrusion, the second connecting structure may be the above-mentioned protruding piece provided with a through groove, and a notch is provided on a side of the through groove away from the fixing frame 400.

In some embodiments, as shown in fig. 1, 2, 9 and 10, the button 100 is provided with a first limit structure 120, and the fixing frame 400 is provided with a second limit structure 440. In one embodiment, the first position-limiting structure 120 is a protrusion having a curved surface, and the second position-limiting structure 440 is a groove, the protrusion is located in the space defined by the groove, and the curved surface of the protrusion can rotate relative to the inner wall of the groove. In other embodiments, the first limiting structure is a groove, and the second limiting structure is a protrusion with an arc surface, which can be selected according to actual conditions.

The arrangement of the first position-limiting structure 120 and the second position-limiting structure 440 can reduce the rotational deviation generated during the rotation of the button 100, thereby reducing the situation that the button 100 is separated from the fixing frame 400.

In some embodiments, as shown in fig. 9, the number of the first connecting structures 110 is two, and two first connecting structures 110 are spaced apart from each other near the middle of the button 100. The number of the first position-limiting structures 120 is two, and the two first position-limiting structures 120 are arranged at two sides of the button 100 at intervals. The first connecting structure 110 and the first limiting structure 120 are both in the same line with the rotation axis of the button 100.

For the embodiment in which the button 100 is directly and rotatably connected to the functional element 200, the button 100 may be provided with the first connecting structure 110 and the first limiting structure 120, and the functional element 200 may be provided with the second connecting structure 430 and the second limiting structure 440; or the button 100 can be provided with the second connecting structure 430 and the second limiting structure 440, and the functional element 200 can be provided with the first connecting structure 110 and the first limiting structure 120.

For the embodiment with the fixing frame 400, the fixing frame 400 and the functional element 200 may be connected in a fixed manner or in a detachable manner.

In some embodiments, as shown in fig. 10, the fixing frame 400 is provided with a mounting groove 410, the functional element 200 is at least partially accommodated in the mounting groove 410, and the functional element 200 is connected with a groove wall or a groove bottom of the mounting groove 410. For example, in some embodiments, the functional element 200 is snapped into the mounting slot 410. For another example, in other embodiments, the functional element 200 is inserted into the mounting groove 410, the functional element 200 has a mounting structure 210, and the mounting structure 210 is connected to a groove wall or a groove bottom of the mounting groove 410.

In some embodiments, as shown in fig. 10, at least one mounting through slot 411 is opened at the bottom of the mounting slot 410. One side of the functional element 200 close to the bottom of the mounting groove 410 is provided with mounting structures 210 which are the same as the mounting through grooves 411 in number and correspond to one another, and the mounting structures 210 can penetrate through the mounting through grooves 411 and are clamped with the mounting through grooves 411. For example, the number of the installation through grooves 411 may be four, and the installation through grooves 411 are respectively disposed at four corners of the bottom of the installation groove 410 or near the corners of the wall of the installation groove 410.

In some embodiments, referring back to fig. 1, 5 and 8, the mounting structure 210 can be a protrusion having a triangular structure 230 on a sidewall. When the functional element 200 is mounted on the fixing frame 400, the triangular structure 230 passes through the mounting through slot 411, and the side surface where the bottom edge of the triangular structure 230 is located abuts against the side, far away from the button 100, of the mounting through slot 411, so that the mounting structure 210 is clamped with the mounting through slot 411.

In some embodiments, as shown in fig. 2, 4 and 10, the fixing frame 400 is provided with a receiving groove 420, and the receiving groove 420 can receive a portion of the rod 310 protruding from the first surface 201 and/or the second surface 202. An embodiment in which two ends of the rod 310 protrude from the first surface 201 and the second surface 202 is described as an example.

In this embodiment, the mounting groove 410 and the inner wall of the functional element 200 abutting or approaching the first surface 201, and the mounting groove 410 and the inner wall of the functional element 200 abutting or approaching the second surface 202 are both provided with the receiving groove 420. The extending direction of the receiving groove 420 is the same as the length direction of the rod body 310. The receiving groove 420 is slightly larger than the portion of the rod 310 protruding out of the functional element 200, so that when the rod 310 rotates relative to the fixing frame 400, there is enough space for rotation.

When the small-angle switch is used, a user can press the button 100 through a small angle (within 1 degrees), so that the button 100 drives the transition piece 300 to rotate, the on-off state of the conductive assembly 600 is further changed, and the on-off state of the switch is changed. In addition, the distance between the rotation center 321 of the transition piece 300 of the switch and the surface of the button 100 pressed by the user can be less than 4mm, so that the current requirement of the user on an ultrathin switch is met, and the market value is high.

In addition, the button 100 can directly abut against the rod body 310 of the transition piece 300, so that more transmission components are avoided between the button 100 and the transition piece 300, transmission levels can be reduced as much as possible, transmission consumption is reduced, and switch parts are simplified.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
