滚轮控制模组

Abstract

本实用新型公开了一种滚轮控制模组，包括：滚轮、编码器、接触开关、弹性复位件、动支架、静支架；滚轮装在动支架上，编码器与滚轮相连，滚轮转动以使编码器进行编码；动支架背向滚轮的一侧设置有接触开关，静支架对应接触开关设置有凸点，弹性复位件对应接触开关和触点设置，动支架可相对静支架上下滑动，当按压动支架下滑时，接触开关与触点相接触，并使弹性复位件被压缩而具有复原势能，实现接触开关的导通功能，当不按压动支架，接触开关在在弹性复位件的复原势能作用下向上滑动，从而带动动支架回复原位。

Claims

1. A roller control module, characterized in that, include: Roller (1); An encoder (2) is connected to the roller (1), and the roller (1) rotates to enable the encoder (2) to encode. A movable support (3) is provided, wherein the roller (1) is rotatably connected to the movable support (3), and a contact switch (31) is provided on the side of the movable support (3) facing away from the roller (1); A stationary support (4) is provided with a contact (41) corresponding to the contact switch (31). The moving support (3) can slide up and down relative to the stationary support (4) to drive the contact switch (31) to contact or separate from the contact (41). The movable support (3) is provided with a protruding rib (32) extending in a direction perpendicular to the axial direction of the roller (1). The stationary support (4) is provided with a sliding groove (42) corresponding to the protruding rib (32). The movable support (3) can slide up and down relative to the stationary support (4) by sliding the protruding rib (32) into the sliding groove (42).

2. The scroll control module of claim 1, wherein, The rib (32) extends toward the stationary support (4) to form a protruding end (321). The protruding end (321) protrudes out of the moving support (3). The groove (42) is recessed away from the moving support (3) to form a recessed position (421). The protruding end (321) is slidably fitted in the recessed position (421). When the moving support (3) slides up and down relative to the stationary support (4), the protruding end (321) is always located in the recessed position (421) to limit the range of motion of the moving support (3) in the axial direction of the roller (1).

3. The scroll control module of claim 1, wherein, The movable support (3) is also provided with a boss (34) extending in a direction perpendicular to the axial direction of the roller (1). The stationary support (4) is provided with a through hole (44) corresponding to the boss (34). The boss (34) slides in the through hole (44). When the movable support (3) slides up and down relative to the stationary support (4), the boss (34) slides in the same direction in the through hole (44) to limit the sliding range of the movable support (3) and its range of motion in the axial direction of the roller (1).

4. The scroll control module of claim 3, wherein, The boss (34) has an inclined surface (341) on the side facing the static support (4), and the lower side of the inclined surface (341) is located outside the through hole (44) to increase the range of sliding of the boss (34) within the through hole (44).

5. The scroll control module of claim 3, wherein, At least two bosses (34) are provided on the same side of the moving support (3), and the projection of each boss (34) is arranged along the axial direction of the roller (1).

6. The scroll control module of claim 3, wherein, The movable support (3) is provided with bosses (34) on both sides of its opposite sides.

7. The roller control module according to any one of claims 1 to 6, wherein Also includes: An elastic reset member (5) is provided corresponding to the contact switch (31) and the contact (41) to drive the contact switch (31) to separate from the contact (41).

8. The scroll control module of claim 7, wherein, The static support (4) is also provided with a mounting groove (45) for mounting the elastic reset member (5).

9. The scroll control module of claim 8, wherein, The elastic reset member (5) is arranged in a ring shape, and the mounting groove (45) is arranged in a corresponding ring shape and surrounds the contact point (41).
