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.

[0024] Please see Figure 1-7 As shown, a circuit board integrating a touch button module and a display module includes a substrate 1. A control mechanism 2 is mounted on the substrate 1. The control mechanism 2 includes a display module 201. The display module 201 is electrically connected to the substrate 1. A mounting plate 202 is electrically connected to the substrate 1. The mounting plate 202 has a mounting groove 205. A touch module 203 is slidably connected to the mounting groove 205. A plurality of equidistantly distributed metal pieces 207 are mounted on the top of the mounting plate 202. A plurality of equidistantly distributed metal springs 210 are mounted on the bottom of the touch module 203. The bottoms of the plurality of metal springs 210 respectively abut against the tops of the plurality of metal pieces 207. A cleaning mechanism 3 is mounted on one side of the touch module 203.

[0025] As a technical optimization of this utility model, the metal spring 210 has an overall ">" shaped structure and a "V" shaped bottom, which makes the metal spring 210 more elastic and allows it to make good contact with the metal sheet 207 to achieve signal transmission.

[0026] As a technical optimization of this utility model, the cross-section of the mounting groove 205 and the bottom of the touch module 203 are respectively "convex" shaped structures, and the area of ​​the mounting plate 202 is equal to the area of ​​the touch module 203, which facilitates the stable sliding engagement of the touch module 203 and the top of the mounting plate 202, and makes subsequent disassembly and maintenance convenient.

[0027] As a technical optimization of this utility model, two bolts 204 are vertically connected to the touch module 203, and two threaded holes 206 are provided on the mounting plate 202. The bolts 204 are internally threaded to the threaded holes 206. The cooperation between the bolts 204 and the threaded holes 206 facilitates locking the touch module 203 and the mounting plate 202 after they are engaged, preventing loosening.

[0028] As a technical optimization of this utility model, a plurality of equally spaced rubber blocks 208 are installed on one side of the mounting plate 202. The rubber blocks 208 are cylindrical structures. One side of the touch module 203 abuts against the plurality of rubber blocks 208. The installation of the rubber blocks 208 facilitates the contact of the touch module 203 after it slides into place, thus playing a role in preventing collision.

[0029] As a technical optimization of this utility model, the rubber block 208 is a cylindrical "T"-shaped structure. One end of the rubber block 208 extends to the inner side of the mounting plate 202. A compression spring 209 is connected between one end of the rubber block 208 and the interior of the mounting plate 202. The rubber block 208 is slidably connected to the mounting plate 202 through the compression spring 209. With the cooperation of the compression spring 209, the rubber block 208 has elastic sliding, which helps to prevent collision and contact during the installation of the touch module 203, and makes the touch module 203 installed stably and without loosening.

[0030] As a technical optimization of this utility model, the cleaning mechanism 3 includes a connecting plate 302. The connecting plate 302 is installed on one side of the touch module 203, and a brush 303 is installed at the bottom of the connecting plate 302. The brush 303 is slidably connected to the mounting groove 205. The installation of the connecting plate 302 facilitates the connection of the brush 303. When the touch module 203 is disassembled and slid, the multiple metal pieces 207 are cleaned, preventing debris from affecting the conductivity.

[0031] As a technical optimization of this utility model, a through groove 301 is provided on one side of the mounting plate 202. The through groove 301 is connected to the mounting groove 205. The opening of the through groove 301 facilitates the brush 303 to slide inside the mounting groove 205 and push out and clean debris.

[0032] As a technical optimization of this utility model, the substrate 1 is provided with a plurality of fixing holes 5, and a rubber ring 4 is engaged with the inner side of the fixing hole 5. The fixing hole 5 facilitates the detachable installation of the substrate by screws. The rubber ring 4 acts as a buffer when the substrate 1 is impacted, and prevents the screws from squeezing and breaking the substrate.

[0033] In use, the substrate 1 is first detachably installed to the device housing using screws. Then, the touch module 203 is inserted into the mounting groove 205 on the mounting plate 202, allowing the touch module 203 to slide and connect with the mounting plate 202. During the sliding installation and removal of the touch module 203, the brush 303 on the touch module 203 cleans the inside of the mounting groove 205, removing debris from the multiple metal pieces 207 and improving subsequent conductivity. After the touch module 203 slides to a certain position, it comes into contact with multiple rubber blocks 208. Then, the two bolts 204 are rotated to thread the bolts 204 into the threaded holes 206, thereby locking the touch module 203 and ensuring a stable and secure installation of the touch module 203 and the mounting plate 202. During maintenance, by removing the two bolts 204, the touch module 203 slides out a certain position from the contact of the multiple rubber blocks 208, facilitating the disassembly and maintenance of the touch module 203.
