[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] This utility model embodiment provides a button device 100, combined with... Figures 1 to 3 As shown, it includes a housing 1, a base 2, a back cover 3, a circuit board 4, and a button 5.

[0033] The housing 1 includes a cylindrical sidewall 11, an annular retaining ring 13 extending radially outward from one end of the sidewall 11, and at least two racks 12 fixed at intervals to the outer periphery of the sidewall 11. Both racks 12 extend radially along the sidewall 11, and each rack 12 includes a plurality of equally spaced serrations 121. The serrations 121 of adjacent racks 12 are staggered radially along the sidewall 11. The retaining ring 13 is used to fix the partition door to one side along its thickness direction when it is moved.

[0034] The base 2 includes a ring-shaped fixed wall 21 sleeved outside the side wall 11 and a buckle 22 formed on the inner circumference of the fixed wall 21 and elastically connected to the fixed wall 21. The fixed wall 21 is slidably connected to the side wall 11. The number of buckles 22 is the same as the number of racks 12. Each buckle 22 and its corresponding rack 12 form a limiting engagement, so that the base 2 can move along the rack 12 towards the limiting ring 13, but cannot move away from the limiting ring 13.

[0035] The sides of the serrations 121 at the same end near the sidewall 11 in each rack 12 are inclined; the sides of the buckle 22 corresponding to the inclined surfaces of the serrations 121 are inclined oppositely. This design allows the buckle 22 to fall more smoothly into the space between two adjacent serrations 121 in the corresponding rack 12 and form a limiting engagement.

[0036] The base 2 also includes a spring arm 23 extending from one end of the fixed wall 21 near the limiting ring 13 to the other end, and a buckle 22 is fixed to the end of the spring arm 23 away from the limiting ring 13. This design can improve the elasticity between the buckle 22 and the fixed wall 21, so that the buckle 22 can better abut against the two adjacent teeth 121 in the corresponding rack 12 and form a limiting engagement, thereby improving the reliability of the limiting engagement.

[0037] The side wall 11 is provided with multiple recessed grooves 112 corresponding to the positions of multiple racks 12. The multiple racks 12 are fixed to the bottom of the grooves 112 and the serrations 121 are exposed on the side wall 11. The buckle 22 extends into the corresponding groove 112 and abuts against the rack 12. The spring arm 23 extends into the groove 112. This design can guide and limit the base 2 and prevent the buckle 22 from disengaging from the rack 12.

[0038] The base 2 also includes a mounting portion 24 formed by the radially outward extension of the outer periphery of the fixed wall 21, and a plurality of mounting holes 25 that pass through the mounting portion 24 and are spaced apart from each other. During installation, the base 2 can be fixed to the other side of the movable partition door along its thickness direction by screws or bolts passing through the mounting holes 25.

[0039] The back cover 3 is housed and fixed inside the side wall 11; the circuit board 4 is fixed to the back cover 3.

[0040] The rear cover 3 includes an annular peripheral wall 31, four recessed notches 32 formed by the peripheral wall 31 from one end near the limiting ring 13 to the other end and spaced apart from each other, and two limiting parts 33 fixed to the outer periphery of the peripheral wall 31. Each pair of notches 32 is respectively provided on both sides of the limiting part 33, and the two limiting parts 33 are respectively located on opposite sides of the peripheral wall 31 and are both near the end of the peripheral wall 31. The circuit board 4 is fixed to the side of the peripheral wall 31 near the limiting ring 13. The side wall 11 is provided with two limiting holes 111 through it corresponding to the positions of the two limiting parts 33, and the two limiting parts 33 are respectively inserted into the two limiting holes 111. This design allows the limiting parts 33 to be inserted into the limiting holes 111 through elastic action, so as to achieve the fixation between the rear cover 3 and the housing 1, and facilitate the disassembly and assembly of the rear cover 3.

[0041] The back cover 3 also includes two locking posts 34 fixed to the peripheral wall 31 near the circuit board 4 and spaced apart from each other; the circuit board 4 has two locking holes 42 through it corresponding to the positions of the two locking posts 34, and the two locking posts 34 are respectively inserted into the two locking holes 42. This allows the circuit board 4 to be stably fixed to the back cover 3.

[0042] Button 5 is inserted into one end of side wall 11 near the limiting ring 13 and forms a sliding connection with side wall 11. Button 5 extends into side wall 11 and abuts against button 41 on circuit board 4.

[0043] During installation, the limiting ring 13 is attached and fixed to one side of the movable partition door by adhesive on the side near the back cover 3. At this time, the button 5 is exposed on the door panel for the user to press.

[0044] The button device 100 also includes a socket 6 fixed to the side of the circuit board 4 away from the limiting ring 13, with the socket 6 protruding from the end of the side wall 11 away from the limiting ring 13. This design allows for quick connection directly to the internal plug of the movable partition door via the socket 6.

[0045] The button device 100 also includes two pins 7 fixed to the circuit board 4 and spaced apart from each other. The two pins 7 extend radially along the side wall 11 toward the limiting ring 13 and protrude outwards. This design allows backup power to be introduced through the pins 7 to provide power to the movable partition door in the event of a power outage or power failure.

[0046] In the button device 100 of this embodiment, such as Figure 3As shown, the sidewall 11 has two racks 12 arranged opposite each other. The distance between two adjacent serrations 121 on the same rack 12 is 0.5mm. However, since the serrations 121 of the two adjacent racks 12 are staggered along the radial direction of the sidewall 11, the distance between two adjacent serrations 121 of the two racks 12 becomes 0.25mm along the radial direction of the sidewall 11. This allows for a smaller spacing in the thickness direction of the button device 100 without increasing cost or manufacturing complexity. Of course, depending on actual needs, the sidewall 11 can also be designed with three, four, or five racks 12, and the distance between two adjacent serrations 121 in each rack 12 can be adapted, such as to 0.15mm, 0.11mm, 0.44mm, 0.52mm, etc.

[0047] Compared with the prior art, the button device 100 in this embodiment provides at least two spaced racks 12 on the outer periphery of the side wall 11, with the serrations 121 of the two racks 12 staggered along the axial direction of the side wall 11. It also designs buckles 22 on the fixed wall 21 to form an elastic connection with the fixed wall 21, with the number of buckles 22 being the same as the number of racks 12. Each buckle 22 and its corresponding rack 12 form a limiting engagement. This allows the limiting ring 13 to be fixed to one side of the partition door along its thickness direction when it moves, and the base 2 to be fixed to the moving part. Along the other side of the movable partition door along its thickness direction, the overall thickness of the button device 100 can be adjusted by the limiting engagement between the buckle 22 and the rack 12, so that the button device 100 can be completely fixed to the movable partition door of different thicknesses without any loosening. In addition, since the serrations 121 of the two racks 12 are staggered along the axial direction of the side wall 11, a smaller spacing in the thickness direction of the button device 100 can be adjusted without increasing cost or manufacturing difficulty, effectively improving the accuracy and reliability of the button device 100 during installation. Furthermore, when the button device 100 in this embodiment needs to be removed, it is not necessary to remove the door panel of the movable partition door, and it can be used for various types of door panels, such as soft boards and hard boards, to achieve complete fixation without any loosening.
