When the circuit device 2 , the knob 3 , the button 4 and the inner ring member 51 are to be assembled to the housing 1 , the circuit board 21 is firstly locked to the frame body 121 of the frame 12 through the screws 23 . Next, the inner ring 51 is assembled to the knob 3 . During the assembly process, each of the hooks 512 is first pulled outwards to bend and deform relative to the ring portion 511 and to accumulate restoring elastic force. Then, each of the hooks 512 is moved to a position aligned with the corresponding slot 315 , and the abutting inclined surface 515 of each of the hooks 512 is abutted against the corresponding inclined surface 317 . Each of the hooks 512 is released so that it is reset by the accumulated reset elastic force, and the corresponding abutting slope 515 is guided through each of the inclined surfaces 317 to slide, so that each of the hooks 512 can be locked in the corresponding position after reset. inside the card slot 315. At this time, the inner ring member 51 is fixed on the knob 3, and the annular surface 513 of the inner ring member 51 faces the ring portion 312 of the knob and is spaced therefrom.

Next, the sensor 22 is inserted into the ring portion 511 of the inner ring member 51 , and then the shaft 221 is inserted into the center groove 314 of the knob 3 and locked at the center through the locking blocks 222 The slot 314 connects the sensor 22 to the knob 3 . Then, the button 4 is placed in the accommodating groove 318 , so that the button 4 is fixed to the rod portion 223 of the shaft 221 through the sleeve 41 .

A structure formed by assembling the aforementioned components is inclined at an appropriate angle and penetrates into the opening 113 from the outside of the housing 1 , and then the structure is turned upright. During the process of the structure being turned upright, when the chamfered surface 514 of the inner ring member 51 contacts and is blocked by the hook portion 522 of the blocking member 52 , the hook portion 522 imparts a portion of the chamfered surface 514 The force will cause the ring portion 511 to bend and deform inwardly and accumulate restoring elastic force. After the loop portion 511 passes over the hook portion 522 , the loop portion 511 can be reset by the accumulated restoring elastic force. Finally, the sensor 22 is soldered to the circuit board 21 to complete the assembly operation.

Referring to FIGS. 1 and 4 , after the aforementioned components are assembled, the disk body 31 of the knob 3 exposes the base wall 111 of the housing 1 through the opening 113 , thereby allowing the The button 4 also exposes the base wall 111 to provide the user with a pressing operation. A part of the knob 3 protrudes out of the side wall 112 of the housing 1 through the side through hole 114 , wherein the outer peripheral wall 32 has a side wall 112 that protrudes out of the side through hole 114 and exposes the side wall 112 The operation part 323, the user can perform the rotation operation of the knob 3 by sliding the operation part 323.

Since the hook portion 522 of the blocking member 52 is spaced between the ring portion 312 of the disk body 31 and the ring surface 513 of the inner ring member 51 , the hook portion 522 acts to stop the ring surface The role of 513. Since the blocking member 52 corresponds to the position of the side through hole 114 and is located between the inner ring member 51 and the operating portion 323 , when the user pulls the operating portion 323 along a pulling direction D1 with fingers, the disk After the position of the body 31 close to the operating portion 323 drives the position of the inner ring member 51 close to the stop member 52 to move for a short stroke, the ring surface 513 will be stopped by the hook portion 522, so that it can quickly stop. The effect of the inner ring member 51 is prevented. This can prevent the user from pulling up the knob 3 from the operating portion 323 to cause the knob 3 to separate from the shaft 221 and fall off.

On the other hand, since the shielding wall 53 shields the portion of the back end 322 of the outer peripheral wall 32 corresponding to the operation portion 323 and is spaced apart from it, when the user wants to pull the back end along the pulling direction D1 through fingers When 322 corresponds to the part of the operation part 323 , the user's fingers will be blocked by the shielding wall 53 and cannot touch the part of the back end 322 corresponding to the operation part 323 . In this way, the knob 3 can be prevented from falling off due to the user pulling up the knob 3 from the back end 322 .

Referring to FIGS. 4 and 5 , since the wall portion 521 of the blocking member 52 is spaced between the inner ring member 51 and the portion of the inner peripheral surface 321 of the outer peripheral wall 32 corresponding to the operating portion 323 , the The wall portion 521 acts to block the operation portion 323 . When the user presses the operating portion 323 along a pressing direction D2 with fingers, the wall portion 521 blocks the portion of the inner peripheral surface 321 corresponding to the operating portion 323 to prevent the operating portion 323 from moving. Thereby, the situation that the central groove 314 of the knob 3 is separated from the locking blocks 222 of the shaft 221 can be prevented. Since the stopper 52 will not contact and interfere with the inner ring 51 and the knob 3 , and the shielding wall 53 will not contact and interfere with the knob 3 , therefore, when the user slides the operating portion 323 , the knob 3 It can smoothly rotate relative to the stopper 52 and the shielding wall 53 .

It should be noted that although the electronic device 100 is described with the button 4 as an example, in other implementations of this embodiment, the electronic device 100 may also omit the button 4 .

To sum up, in the electronic device 100 of this embodiment, the hook portion 522 of the blocking member 52 can play the role of blocking the ring surface 513 of the inner ring member 51, thereby preventing the user from The knob 3 is pulled up at the operating portion 323 to cause it to fall off. In addition, because the shielding wall 53 shields the portion of the back end 322 of the outer peripheral wall 32 corresponding to the operating portion 323 , the knob 3 can be prevented from falling off due to being pulled up by the user from the back end 322 . Furthermore, since the wall portion 521 of the blocking member 52 is spaced between the inner ring member 51 and the portion of the inner peripheral surface 321 of the outer peripheral wall 32 corresponding to the operating portion 323 , the user can be prevented from applying pressure. When the operating portion 323 causes the central groove 314 of the knob 3 to be separated from the shaft 221, the object of the present invention can indeed be achieved.

However, the above are only examples of the present invention, and should not limit the scope of the present invention. All simple equivalent changes and modifications made according to the scope of the application for patent of the present invention and the contents of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
