Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 An e-ink display controller integrating a SOC chip, in one embodiment, includes a panel 1. An annular mounting sleeve 2 is welded to the rear outer wall of the panel 1. A controller body 3 is disposed inside the mounting sleeve 2. Bolts are provided on both outer walls of the mounting sleeve 2, and the controller body 3 is fixedly connected to the inner wall of the mounting sleeve 2 by bolts. An array of positioning sleeves 4 are fixedly connected to the rear outer wall of the panel 1 inside the mounting sleeve 2. An array of positioning posts 5 are fixedly connected to the inside of the controller body 3, with each positioning post 5 corresponding to a positioning sleeve 4. A chip mounting plate 6 is disposed between the controller body 3 and the panel 1, and an SOC chip is mounted on the chip mounting plate 6. Through holes are provided at the four corners of the chip mounting plate 6, through which the positioning posts 5 pass and insert into the positioning sleeves 4 to fix the chip mounting plate 6.

[0024] A mounting sleeve 2 is welded to the rear side of panel 1. The controller body 3 is fixed inside the mounting sleeve 2 with bolts, facilitating overall assembly and disassembly. Panel 1 has an array of positioning sleeves 4, which connect to positioning posts 5 on the controller body 3 to ensure precise alignment of the chip mounting plate 6. One side of the chip mounting plate 6 is tightly fitted with the positioning sleeve 4, and the other side of the chip mounting plate 6 is tightly fitted with the controller body 3, preventing displacement of the chip mounting plate 6.

[0025] In this embodiment, the chip mounting plate 6 is quickly installed and removed by inserting the positioning sleeve 4 and the positioning post 5. Users only need to use common screwdrivers to complete the operation, which improves maintenance efficiency. At the same time, the design of the positioning sleeve 4 closely adhering to the chip mounting plate 6 ensures the stability of the SOC chip and avoids poor contact problems caused by vibration or impact.

[0026] In embodiment 2, a charging compartment 10 is provided on one side of the panel 1, and a battery mounting plate 7 is provided on the part of the charging compartment 10. The rear side wall of the battery mounting plate 7 has adjacent button battery mounting holes, which are filled with button batteries 8. The top and bottom inner walls of the side of the charging compartment 10 are provided with wedge-shaped grooves 11, and the top and bottom sides of the side of the battery mounting plate 7 are provided with matching wedge blocks 9. After the battery mounting plate 7 is inserted into the charging compartment 10, the wedge-shaped grooves 11 and the wedge blocks 9 are in an interference fit.

[0027] The charging compartment 10 has a slidingly connected battery mounting plate 7 for securing the button cell battery 8. The wedge-shaped grooves 11 at the top and bottom of the charging compartment 10 are interference-fitted with the wedge-shaped blocks 9 on the battery mounting plate 7, ensuring that the battery mounting plate 7 will not loosen after insertion. Users can easily remove the button cell battery 8 by simply pulling out the battery mounting plate 7.

[0028] In this embodiment, the interference fit between the wedge groove 11 and the wedge block 9 makes it easier to replace the button battery 8. The battery mounting plate 7 can be slid out, and the user can replace the battery without disassembling the controller body 3, which reduces the cost of use.

[0035] Working principle:

[0036] Installation and Fixing: Insert the controller body 3 along the mounting sleeve 2 and fix it with bolts. The chip mounting plate 6 is precisely installed through the cooperation of the positioning post 5 and the positioning sleeve 4 to ensure reliable circuit connection.

[0037] Power supply and maintenance: The button battery 8 is inserted into the charging compartment 10 via the battery mounting plate 7. The interference fit between the wedge block 9 and the wedge groove 11 prevents the battery mounting plate 7 from becoming loose. To replace the button battery 8, simply slide the battery mounting plate 7 out.

[0038] Signal transmission and heat dissipation: Cable 13 and terminal block 14 have an outward extension feature, facilitating communication between external devices and the controller body 3. The heat sink 15 dissipates heat through natural convection, keeping the SOC chip operating at a suitable temperature.

[0039] Display and control: The e-ink screen 16 receives signals from the controller body 3 and displays the content. The user can adjust the display mode or control the zones through the sub-control switch 17.
