[0029] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0030] Please refer to Figures 1 to 8 A foldable POS machine base, the core structure of which consists of a U-shaped horizontal sheet metal part 1, a lever arm sheet metal part 2, and a connecting sheet metal part 3. The U-shaped horizontal sheet metal part 1 is symmetrically provided with first bending ears 4 on both sides, while the lever arm sheet metal part 2 is equipped with outward-extending bending connecting arms 5 on both sides. The connecting sheet metal part 3 is provided with symmetrical second bending ears 6. These bending ears and bending connecting arms are hinged to each other via a damping hinge 7, realizing the folding function of the base. To improve aesthetics and durability, the entire internal structure is encased in a plastic shell 8.

[0031] The design of the plastic housing 8 is equally meticulous: it comprises an upper cover 10, a front cover 11, a rear cover 12, an upper shell 13, and a lower shell 14. The bottom of the U-shaped horizontal sheet metal 1 is securely connected to the base sheet metal 9 via bolts, while the upper cover 10 is screwed onto the base sheet metal 9. The front cover 11 and rear cover 12 are cleverly positioned around the periphery of the lever arm sheet metal 2, secured together by a snap-fit ​​connection for both aesthetics and stability. The periphery of the connecting sheet metal 3 is comprised of an upper shell 13 and a lower shell 14. Both housings feature a cleverly designed semi-cylinder 15 on their backs, cleverly concealing the damping hinge 7 and enhancing the overall aesthetics.

[0032] Furthermore, positioning grooves 17 are designed inside both the upper shell 13 and the lower shell 14, which closely mate with the positioning bends 16 on the connecting sheet metal 3 to ensure structural stability. Flanged edges 18 are also provided on both sides of the connecting sheet metal 3. These flanges closely contact the inner walls of the upper shell 13 and the lower shell 14, further enhancing the secure connection.

[0033] The design of the upper cover 10 is also unique. A boss 19 is provided near the first bending ear 4, while the rest of the body is thinner, which not only saves material but also improves the aesthetics. Below the arm sheet metal 2, an arc-shaped cover plate 20 is cleverly configured. It is located between the two bent connecting arms 5, not only shielding the damping hinge 7, but also enhancing the overall aesthetics. The horizontal connection portion 21 on the arc-shaped cover plate 20 perfectly matches the mounting hole 22 on the boss 19, facilitating installation and removal. The horizontal connection portion 21 and the U-shaped horizontal sheet metal 1 are connected by bolts.

[0034] To better manage the wiring harness, a wiring harness channel 23 is designed on the horizontal connecting portion 21 and the base plate sheet metal 9. Notches 24 for wiring harness clearance are also provided on the base plate sheet metal 9 and the upper cover 10. Furthermore, a removable baffle 25 is mounted on the front cover 11, with a hanging plate 26 on it. This baffle 25 mates with a hanging slot 27 on the front cover 11 to form a wiring harness retaining slot 28, facilitating the organization and positioning of the wiring harness.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
