The toothed disc 314 is sleeved with the bottom of the right-angle shaft 313, and the other end of the right-angle shaft 313 is spherical. A connecting ball 312 is sleeved on the outer side of the other end of the right-angle shaft 313, and a first slide bar 308 is spherically sleeved on the side of the connecting ball 312 symmetrical to the right-angle shaft 313, and a fixed sleeve shaft 305 is sleeved on the outer side of the first slide bar 308, and the other end of the fixed sleeve shaft 305 is fixedly connected to the outer side of the contact knob 4;

[0043] By rotating the toothed disc 314, the toothed arc plate 304 meshing therewith can be driven to rotate, and by pulling the toothed disc 314, the position of the toothed disc 314 can be adjusted through the right-angle shaft 313 sleeved on the top thereof, thereby facilitating changing the triggering mode of the encoder body 1.

[0044] The side-pressed miniature incremental encoder with a switch provided by the present invention realizes changing the encoder components and contact switch components in a superimposed state to a horizontal distribution through the contact knob and the switch components arranged in arrays on both sides thereof, thereby reducing the thickness of the encoder and enabling it to be applied to thinner devices.

[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0048] Example 1, please refer to Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 A side-pressed miniature incremental encoder with a switch, wherein the other end of the first slide bar 308 is rotatably sleeved with a connecting shaft 309, and the outer side of the other end of the connecting shaft 309 is sleeved with a second slide bar 310, and the bottom of the second slide bar 310 near one end of the connecting shaft 309 is concave, and a clamping shaft extends from one end of the connecting shaft 309 near the second slide bar 310, and a reset spring 311 is fixedly installed on the other end of the second slide bar 310, and the second slide bar 310 is fixedly connected to the inside of the fixed sleeve shaft 305 through the reset spring 311;

[0049] When the right-angle shaft 313 is pulled by the toothed disc 314, the first slide bar 308, the connecting shaft 309, the second slide bar 310 and the return spring 311 are synchronously pulled through the connecting ball 312, thereby facilitating the full change of the position of the toothed disc 314 and resetting it through the return spring 311.

[0050] Please refer to Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 A side-pressed miniature incremental encoder with a switch, wherein a fixed sleeve shaft 305 has a limit groove 306 extending through one end of the fixed sleeve shaft 305 near the connecting ball 312, and the fixed sleeve shaft 305 is sleeved with an end of the connecting shaft 309 near the second slide bar 310 through the limit groove 306;

[0051] The limiting groove 306 is engaged with the connecting shaft 309 to facilitate fixing the connecting shaft 309 and the second sliding rod 310 , thereby facilitating limiting the first sliding rod 308 .

[0052] Further, such as Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a side groove 307 is provided on one side of the fixed sleeve shaft 305 close to one end of the connecting ball 312, a first spherical rod 315 is fixedly mounted on the side wall of the first slide bar 308, the first slide bar 308 is sleeved with the first spherical rod 315 through the side groove 307, and one end of the first spherical rod 315 is spherical;

[0053] The side groove 307 cooperates with the first spherical rod 315 to limit the first sliding rod 308, the connecting shaft 309 and the second sliding rod 310 when they slide.

[0054] Further, such as Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, one end of the first spherical rod 315 away from the first sliding rod 308 is spherically sleeved with a two-way telescopic rod 316, and the outer side of the other end of the two-way telescopic rod 316 is sleeved with a second spherical rod 317, and the other end of the second spherical rod 317 is fixedly connected to the side wall of the contact knob 4;

[0055] The first spherical rod 315 drives the bidirectional telescopic rod 316 spherically sleeved therewith to extend under the sliding of the first sliding rod 308 , thereby driving the contact knob 4 to tilt slightly, thereby triggering the encoder body 1 .

[0056] Further, such as Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a spherical shaft extends from the bottom of the middle of the two-way telescopic rod 316, a spring telescopic rod 318 is spherically sleeved at the bottom of the two-way telescopic rod 316, a third spherical rod 319 is spherically sleeved at the outer side of the other end of the spring telescopic rod 318, and the other end of the third spherical rod 319 is fixedly connected to the inner wall of the tooth arc plate 304;

[0057] The bidirectional telescopic rod 316 will synchronously drive the spring telescopic rod 318 to extend synchronously when pulled by the first spherical rod 315 , and it is also convenient for the bidirectional telescopic rod 316 to be connected to the tooth arc plate 304 .

[0058] Further, such as Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a torsion spring 303 is fixedly installed on the inner wall of the tooth arc plate 304, and a base 301 is fixedly installed on the other end of the torsion spring 303. The base 301 is located directly below the contact knob 4. The top of the base 301 is sleeved with a rotating shaft 302 extending outward, and the top of the rotating shaft 302 is fixedly connected to the bottom of the contact knob 4.

[0059] The toothed plate 314 drives the toothed arc plate 304 meshing therewith to move, thereby facilitating the toothed arc plate 304 to synchronously drive the torsion spring 303 to bend and store force. When the toothed arc plate 304 rotates, the contact knob 4 can be pulled to rotate through the third spherical rod 319, the spring telescopic rod 318, the bidirectional telescopic rod 316 and the second spherical rod 317 installed on its inner wall, thereby facilitating the triggering of the encoder body 1.

[0060] Embodiment 2 further optimizes the side-pressed miniature incremental encoder with switch provided in Embodiment 1. Specifically, Figure 4 and Figure 5 As shown, both sides of the encoder body 1 are provided with mounting grooves 5, the mounting grooves 5 are cross-shaped, the encoder body 1 is sleeved with the toothed disc 314 through the mounting grooves 5, and the inner wall array of the mounting grooves 5 is provided with protrusions 6, and the encoder body 1 is clamped with the toothed disc 314 through the protrusions 6;

[0061] The toothed disc 314 can be fixed and limited in position conveniently by means of the provided mounting groove 5 and the matching protrusion 6 .

[0062] Further, such as Figure 4 and Figure 5 As shown, side grooves 7 are provided on both sides of the encoder body 1, and the encoder body 1 is sleeved with the right-angle shaft 313 through the side grooves 7;

[0063] The side groove 7 is provided to facilitate the sleeve-limiting of the right-angle shaft 313 , and because the right-angle shaft 313 and the first slide bar 308 have the same size, the first slide bar 308 can also be sleeve-limited when the position of the toothed disc 314 is adjusted.

[0064] Further, such as Figure 4 and Figure 5 As shown, the top of the encoder body 1 and the housing 2 are both provided with sliding grooves 8 in array, and the sliding grooves 8 are connected with the side grooves 7;

[0065] The sliding groove 8 is provided to facilitate guiding and limiting the switch assembly 3 when it is adjusted.

[0066] The use process of the side-press switch micro incremental encoder provided by the present invention is as follows:

[0067] Encoder trigger mode selection: First, determine the trigger mode of the encoder body 1 according to the thickness of the device. If you install it directly, you can trigger the encoder body 1 by pressing the side.

[0068] Side-press switch: When the encoder body 1 needs to be triggered, the toothed disc 314 is first rotated, and the toothed arc plate 304 meshing therewith and the torsion spring fixedly installed on the inner wall of the toothed arc plate 304 are driven to rotate synchronously through the toothed disc 314. At this time, the torsion spring contracts and stores force. At the same time, when the toothed arc plate 304 rotates, the third spherical rod 319, the spring telescopic rod 318, the two-way telescopic rod 316 and the second spherical rod 317 fixedly installed on the inner wall thereof can also be used to pull the contact knob 4 to rotate, thereby triggering the encoder body 1;

[0069] Switch mode adjustment: If the equipment has sufficient operating space, the top rotation mode can be selected to trigger the encoder body 1 according to the actual situation. First, pull the toothed disc 314 so that the shaft extending from the upper and lower ends of the toothed disc 314 is separated from the protrusion 6. At this time, there are two options;

[0070] The first method: the toothed disc 314 completely extends to the outside of the encoder body 1, and then the toothed disc 314 and the right-angle shaft 313 sleeved inside the toothed disc 314 are rotated until the toothed disc 314 is flipped to the top of the encoder body 1, and then the toothed disc 314 is loosened, so that the toothed disc 314 is reset under the action of the reset spring 311, and the right-angle shaft 313 is limited and fixed by the side groove 7 and the sliding groove 8. At this time, the toothed disc 314 is located at the top of the encoder body 1 and partially extends to the outside of the encoder body 1. At this time, the two sets of toothed discs 314 can be rotated to make the right-angle shaft 313 rotate along the sliding groove 8, and then as described above, the contact knob 4 is driven to rotate, thereby triggering the encoder body 1;

[0071] The second method: continuously pull the toothed disc 314 until the second slide bar 310 slides to the end of the fixed sleeve shaft 305, and then rotate the toothed disc 314. During the rotation process, the toothed disc 314 first drives the right-angle shaft 313 to drive the connecting ball 312, the first slide bar 308 and the connecting shaft 309 to rotate until the connecting shaft 309 is close to the second slide bar 310. The clamping shaft extending from the side of the connecting shaft 309 and the limiting groove 306 provided through the end of the fixed sleeve shaft 305 limit and fix the connecting shaft 309, and then the first slide bar 308 is clamped through the side groove 7. During the pulling process of the toothed disc 314, the two-way telescopic rod 316 and the spring telescopic rod 318 will extend synchronously with the movement of the first slide bar 308. At this time, the toothed disc 314 is completely flipped to the top of the toothed disc 314 and is tilted, while preventing the toothed disc 314 from extending out of the outside of the encoder body 1. At this time, repeat the above content, rotate the two sets of toothed discs 314 along the sliding groove 8, which can drive the contact knob 4 to rotate, thereby triggering the encoder body 1.
