[0028] Please refer to Figures 1 to 5As shown in the figure, this preferred embodiment provides an edge building controller, which includes an upper housing 1, a lower housing 2, and a circuit board 3. A plurality of upright columns 4 extending upward to the upper housing 1 are provided on the lower housing 2. A chuck 5 is provided at the end of the upright column 4. A column cavity 6 that is in one-to-one cooperation and insertion with each upright column 4 is provided on the upper housing 1. A card slot 7 that cooperates with the chuck 5 for locking is provided on the column cavity 6. An installation area for placing the circuit board 3 is provided in the lower housing 2. Each upright column 4 is distributed on the outer circle of the installation area. A buckle 8 is further provided on the lower housing 2, and the buckle 8 is used to lock the circuit board 3 in the installation area.

[0029] Thus, in this edge building controller, the upper housing 1, the lower housing 2, and the circuit board 3 are all fixed by snap connection, which not only ensures the accurate installation position but also ensures the reliable fixing structure. Moreover, no additional connecting parts and tools are required, greatly reducing the installation difficulty and providing a new design idea for the installation structure of various controllers.

[0030] Particularly, windows 9 are respectively opened at the bottom of the lower housing 2 corresponding to the upright columns 4 and the buckle 8. Through the windows 9, the upright columns 4 can be driven to unlock the chuck 5 from the card slot 7, or the buckle 8 can be driven to invalidate the locking function of the buckle 8 on the circuit board 3. Since both the upright columns 4 and the buckle 8 are integrally injection-molded with the lower housing 2 and have a certain elastic capacity, the controller can be disassembled simply by pressing the upright columns 4 or the buckle 8 through the windows 9.

[0031] Furthermore, the lower edge of the chuck 5 protrudes from the surface of the upright column 4, thereby forming a locking surface that cooperates with the edge of the card slot 7 for limiting. An arc block 10 is provided between the locking surface and the upright column 4. The arc block 10 is used to guide the edge of the card slot 7 over the locking surface, making it convenient for the chuck 5 to be unlocked from the card slot 7 and reducing the disassembly difficulty between the upper housing 1 and the lower housing 2.

[0032] Optionally, a plurality of guide columns 11 extending upward to the upper housing 1 are provided on the lower housing 2. The guide columns 11 are used to abut against the inner side wall of the upper housing 1, thereby guiding the upright columns 4 to accurately insert into the column cavity 6, which is beneficial for the upper housing 1 and the lower housing 2 to be assembled in place immediately during assembly and prevent damage to the upper housing 1 and the lower housing 2 caused by misalignment installation.

[0033] Furthermore, four upright columns 4 are provided here, and the four upright columns 4 are distributed in pairs on the left and right sides of the installation area; four guide columns 11 are also provided here, with two of the guide columns 11 provided between the two left upright columns 4 and the other two guide columns 11 provided between the two right upright columns 4. The positions of the upright columns 4 and the guide columns 11 on the lower housing 2 are reasonably arranged without affecting the installation of the circuit board 3, making the internal structure of the controller more compact.

[0034] Optionally, there are two buckles 8, which are distributed on the left and right sides of the installation area and close to the lower side of the installation area. On the inner side wall of the lower housing 2 and above the installation area, there are bumps 12, and the bumps 12 cooperate with the buckles 8 to perform upper limit on the circuit board 3. Due to the existence of the bumps 12, the design quantity of the buckles 8 can be reduced. First, the upper edge of the circuit board 3 is embedded below the bumps 12, and then the lower edge of the circuit board 3 is pressed down and buckled by the buckles 8, so that the circuit board 3 can be fixed on the lower housing 2, and the installation is convenient.

[0035] Optionally, a plurality of support ribs 13 are arranged on the lower housing 2 along the edge of the installation area. The support ribs 13 support the edge of the circuit board 3 to ensure the stable position of the circuit board 3 and reduce the forming requirements of the installation area.

[0036] Furthermore, the support ribs 13 extend upward to form an extension part 14 for lateral limit on the edge of the circuit board 3, so that the support ribs 13 can not only support the circuit board 3 from below, but also perform lateral limit on the circuit board 3 to ensure the position accuracy of the circuit board 3. However, it is not necessary to set the extension part 14 for each support rib 13, and some parts of the circuit board 3 can be directly laterally limited by the inner side wall of the lower housing 2.

[0037] Optionally, a plurality of positioning posts 15 are arranged on the lower housing 2 and in the installation area. Positioning holes corresponding to the positioning posts 15 one by one are opened on the circuit board 3 to ensure the accurate position when the circuit board 3 is placed in the installation area and have a pre-positioning function.

[0038] Optionally, an elastic pressing block 16 pressing on the circuit board 3 is arranged on the upper housing 1. Although the circuit board 3 has been fixed by the buckles 8 on the lower housing 2, the elastic pressing block 16 can further stabilize the position of the circuit board 3 after the upper housing 1 and the lower housing 2 are combined to ensure the reliable installation of the circuit board 3. However, it is not necessary to set a plurality of elastic pressing blocks 16, and only one elastic pressing block 16 needs to be set at the corner of the upper housing 1 as a backup design.

[0039] Specific installation process: 1) Place the circuit board 3 accurately in the installation area according to the limiting effects of the positioning posts 15 and the support ribs 13; 2) Stop the upper edge of the circuit board 3 by the bumps 12, press down the lower edge of the circuit board 3 and buckle it by the buckles 8 to reliably fix the circuit board 3 on the lower housing 2; 3) Close the upper housing 1 accurately on the lower housing 2 along the guiding posts 11. At the same time, insert the upright posts 4 into the column cavities 6, further press the upper housing 1, so that the clamping heads 5 of the upright posts 4 are embedded into the clamping grooves 7 of the column cavities 6, and the upper housing 1 and the lower housing 2 are combined in place and locked.

[0040] Disassembly process: 1) Press the column 4 from the window 9 of the lower housing 2, so that the chuck 5 is disengaged from the card slot 7, and the locking function of the upper housing 1 and the lower housing 2 fails, and the upper housing 1 can be freely separated from the lower housing 2; 2) Press the buckle 8 from another window 9 of the lower housing 2, so that the locking function of the buckle 8 on the circuit board 3 fails, and the circuit board 3 can be freely separated from the lower housing 2.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
