Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an automatically adjustable base for a portable toilet seat, the specific structure and connection method of its components are designed as follows to ensure the stability and efficiency of the adjustment process:

[0028] The seat mounting base 1 has a rectangular groove structure, the depth of which is adapted to the installation requirements of the portable toilet seat. Two 3mm thick fixing plates 5 are symmetrically welded to both sides of its bottom interior. These fixing plates 5 are made of galvanized steel and have a rust-proof surface treatment, effectively resisting corrosion from the humid environment inside the toilet. The fixing plates 5 not only connect and fix the motor track 4, but also further enhance the overall rigidity of the seat mounting base 1, preventing deformation under load. The built-in base reinforcing rib 2 is the core component for improving its structural strength. The cylindrical end cap 6 of the base is made of solid metal, its diameter precisely matching the center opening on the surface of the seat mounting base 1, and is fixed by bolts. The top of the end cap remains flush with the surface of the seat mounting base 1. On the outer surface of the cylindrical end cap 6 of the base, four reinforcing ribs 7 arranged in a cross shape are welded at equal intervals. These reinforcing ribs 7 are made of alloy steel with a right-angled triangular cross section. Their tops are welded to the inner top of the seat fixing base 1 to form a multi-directional force support structure, which increases the load-bearing capacity of the seat fixing base 1 to more than 200kg.

[0029] The motor guide rail 3 is made of wear-resistant cast iron and is long and narrow. Its track groove has a U-shaped cross-section, with the groove width matching the width of the motor track bar 4 to ensure smooth and stable sliding without significant wobbling. Each end of the track groove of the motor guide rail 3 has two 8mm diameter mounting holes 8, threaded inside. M8 screws are used to securely fix the motor guide rail 3 to the frame of the portable toilet seat. After fixing, the motor guide rail 3 remains parallel to the seat frame, with a parallelism error not exceeding 0.5mm. A drive rack 16 is fixed to the inner wall of the track groove of the motor guide rail 3 using precision bolts. The drive rack 16 has a tooth pitch of 5mm, and the tooth surface is hardened to a hardness of HRC50 or higher, significantly improving its wear resistance and extending its service life.

[0030] The motor track bar 4 is a hollow rectangular metal strip, slightly shorter than the motor guide rail 3, with its outer wall tightly fitted to the inner wall of the track groove of the motor guide rail 3. Two threaded locking pins 10 are symmetrically welded to both ends of the surface of the motor track bar 4, which are adapted to the locking holes 9 evenly spaced at both ends of the surface of the fixing plate 5. The inner wall of the locking holes 9 is also threaded. When the threaded locking pins 10 are inserted into the locking holes 9, tightening the nuts achieves a rigid connection between the motor track bar 4 and the fixing plate 5. After connection, there is no relative displacement between the two, ensuring efficient power transmission.

[0031] In the power drive section, a geared motor 11 with dual-shaft output is fixed to the bottom end of the cylindrical end cap 6 of the base via a flange. The rated power of the motor 11 is 50W, and the rated speed is 100r / min. After reduction, the output shaft speed can be reduced to 10r / min, which ensures both the smoothness of seat adjustment and provides sufficient driving force. Electric drive gears 15 are keyed to both output shafts of the motor 11. The module of the electric drive gears 15 is the same as that of the drive rack 16, ensuring precise meshing. Fixed brackets 17, which are L-shaped metal plates, are symmetrically mounted on both sides of the motor 11 and are fixed to the motor body with bolts. A controller interface is located on the outside of the motor 11, and the controller interface is connected to a motor controller via a connecting cable.

[0032] A connecting support plate 18 is welded to the center of the end of the motor track bar 4. The connecting support plate 18 is a rectangular steel plate with a thickness of 5mm. An opening slot, matching the diameter of the motor 11 shaft, is cut into its center. The edges of the opening slot are ground to prevent scratching the shaft. After the shafts at both ends of the motor 11 pass through the opening slots into the inner cavity of the motor track bar 4, the electric drive gear 15 meshes with the drive rack 16. The end of the fixed bracket 17 furthest from the motor 11 is bolted to one side of the connecting support plate 18, preventing the motor 11 from shifting position due to vibration during operation and ensuring the stability of the gear and rack meshing.

[0033] In addition, a sealing plate 13 is attached to the outer side of the seat fixing base 1 via a snap-fit. The sealing plate 13 is made of transparent acrylic material, which facilitates observation of the working status of the internal components and prevents dust and sewage from entering the base. One end of the fixing strip 5 is bent to form a connecting part with a bending angle of 90 degrees. This connecting part is fixed to both sides of the outer side of the seat fixing base 1 by rivets. A socket panel 14 with a waterproof cover is embedded on one side surface of the bent connecting part. The socket panel 14 is electrically connected to the motor 11 through wires to provide a stable power supply to the motor. The waterproof cover can effectively prevent water from splashing into the socket and causing short circuit faults.

[0034] The working principle of this portable toilet seat automatic adjustment base is based on mechanical transmission and structural cooperation. It achieves automatic adjustment of the seat position through motor 11 drive, gear and rack meshing, and guide rail guidance. The specific process is as follows:

[0035] Power output stage: The dual-shaft output motor 11, installed in the fixed bracket 17, is the core power source, and its two output shafts are respectively connected to the electric drive gears 15. When the motor 11 is connected to the power supplied by the socket panel 14, the output shaft drives the electric drive gears 15 to rotate synchronously, converting electrical energy into mechanical kinetic energy.

[0036] Transmission and Drive Stage: The shaft of motor 11 passes through the opening slot of the connecting plate 18 at the end of the motor track 4 into the inner cavity of the track bar, allowing the electric drive gear 15 to precisely mesh with the drive rack 16 in the slide groove of the motor guide rail 3. When the gear rotates, it forms a meshing transmission with the rack, utilizing the linear drive characteristics of the gear and rack to convert the rotational motion of the motor into the linear sliding motion of the motor track bar 4 along the track groove of the motor guide rail 3. At the same time, motor 11 is fixed to the connecting plate 18 by the fixed bracket 17 to ensure the meshing stability of the gear and rack during transmission and to prevent deviation or tooth disengagement.

[0037] Seat linkage adjustment stage: The motor track 4 is locked to the seat fixing base 1 via the threaded locking pins 10 on its surface and the locking holes 9 of the fixing plate 5 inside, forming a rigid linkage structure. When the motor track 4 slides along the motor guide rail 3, it drives the seat fixing base 1 to move back and forth synchronously through the fixing plate 5, thereby realizing automatic adjustment of the seat position. During this process, the motor guide rail 3 provides guiding support for the overall movement, ensuring the accuracy of the adjustment direction; the cross-shaped reinforcing ribs 7 built into the seat fixing base 1 and the cylindrical end cap 6 of the base form a stable structure, bearing the force during the adjustment process, preventing the base from deforming, and ensuring the reliability of the overall operation.

[0038] Auxiliary structure cooperation: The sealing plate 13 on the outside of the seat fixing base 1 protects the internal components, the socket panel 14 provides convenient power access, and the components are connected by screws, nuts and other detachable means, which not only ensures the stability of the structure, but also provides convenience for later maintenance, and further ensures the sustainability of the overall working principle.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
