Detailed Implementation
[0021] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.
[0022] A stepless rotary smart button panel includes a silicone top cover 1, on which an encoder shaft hole 102 and a button panel 51 are provided. The lower edge of the silicone top cover 1 is provided with a silicone reverse buckle 101. The silicone top cover 1 enhances the button feel.
[0023] The base 2 has a base slot 21 on its upper outer edge and a plug hole on its bottom. The lower cover 5 has a through hole on one end and several button holes 52 on the other end edges. Since the buttons are soldered to the button board, in order to prevent the buttons from being desoldered due to pressure during the pressing process, the buttons are placed in the button holes to limit the movement of the button during the pressing process.
[0024] The button panel 6 has an encoder 61 installed at one end of its upper surface, and a row of buttons 62 installed on each of the other two sides of its upper surface. The buttons 62 and the encoder 61 are connected by a printed circuit. The buttons and knobs are set separately so that the backlight of the buttons is clearly displayed in front of the operator.
[0025] The power board 7 has a plug 3 installed at its lower end and electrical components installed on its upper surface. The plug 3 and electrical components are connected by printed circuits. The power supply and buttons are separated, and the heat between the button board and the power board is not affected by each other through physical isolation.
[0026] The power board 7 is fixed to the bottom of the keypad 6. The keypad 6 and the power board 7 are connected by a ribbon cable 12. The lower cover 5 is mounted on the keypad 6 and fixed to the base 2 with screws. The buttons 62 on the keypad 6 are all placed in the button holes 52. The plug 3 extends out of the base 2 from the plug hole. The silicone upper cover 1 is fixed to the lower cover 5, and the silicone snap fastener 101 is engaged in the base slot 21. The shaft end of the encoder 61 passes through the lower cover 5 and the silicone snap fastener 101, and a knob cover 14 and a cap 13 are installed at the end extending out of the silicone snap fastener 101. This installation method provides heat dissipation space between the base and the power board 7, and between the power board and the keypad 6, ensuring the heat dissipation performance of the keypad panel. Furthermore, using a connector to mate the keypad panel with the device greatly increases the reliability of the direct connection between the keypad panel and the device, and also facilitates installation.
[0027] Furthermore, a plurality of positioning posts 22 are evenly installed on the bottom of the base 2, closely abutting its side wall. Threaded holes are machined on the positioning posts 22, and the screws are fitted into these screw holes. The screws pass through the holes on the edge of the lower cover 5, through the key plate, and into the screw holes fitted on the positioning posts, simultaneously fixing the key plate and the lower cover.
[0028] Furthermore, several keypad positioning posts 63 are installed at the bottom of the keypad 6. Each keypad positioning post 63 has a threaded sleeve. The end face of the power board 7 contacts the bottom of the keypad positioning posts 63 and is fixed by screws. The screws pass through the power board from below and engage with the threaded holes on the keypad 6, fixing the power board 7 to the bottom of the keypad 6.
[0029] Furthermore, a sealing ring 9 is installed at the bottom of the base 2 between the plug 3 and the base 2 to ensure the dustproof and waterproof performance of the button panel.
[0030] Furthermore, the bottom of the base 2 is machined with honeycomb holes, and a waterproof and breathable pad 10 is placed on the honeycomb holes. The honeycomb holes are used for heat dissipation, and the addition of the waterproof and breathable pad ensures the waterproof performance of the button panel.
[0031] Furthermore, several buckles 4 are symmetrically installed on both sides of the base 2. The positions where the buckles 4 are installed are also machined with 23 that are embedded in the buckle groove 23 so that the outer end face of the buckle 4 is flush with the side of the base 2. The spring 41 on the buckle 4 is raised upward, so that the button panel has a buckle installation method. Simply align the plug below the button panel with the plug of the device and insert it. The spring 41 on the buckle will lock into the device to complete the fixation of the button panel.
[0032] Furthermore, the silicone top cover 1 is provided with button panels 51, and each button panel 51 is connected to the others by a thin-walled silicone layer. Each button 62 has a backlight, and the silicone top cover 1 and bottom cover 5 have light-transmitting holes machined between the two rows of buttons 62. As shown in the figure, each button hole 52 has three light-transmitting holes next to it, and each light-transmitting hole corresponds to a backlight. Different backlights illuminate to represent different button states.
