[0018] Additionally, a plurality of first limiting protrusions 304 and mounting holes 305 are provided on the surface of the fixing portion 301. The mounting holes 305 penetrate through the fixing portion 301, which improves the connection strength of the components and facilitates the fixed installation of the components.

[0019] Furthermore, the first connecting portion 302 has a hollow inner cavity, and the hollow inner cavity communicates with the mounting holes 305; a second limiting protrusion 306 is provided on the outer sidewall of the first connecting portion 302 to achieve the connection, transition and limiting functions of the hinge.

[0020] Additionally, one end of the upper cover vane 101 has a hollow inner cavity. A plurality of limiting blocks 307 are provided on the sidewall of the hollow inner cavity. An installation groove 308 is formed between adjacent limiting blocks 307. The number of installation grooves 308 is not less than 2. In this embodiment, the number of installation grooves 308 is 2. The buffer member 201 is disposed on the installation groove 308, and a connecting column 309 is further provided at the center of the hollow inner cavity to facilitate the installation and connection of the upper cover vane 101.

[0021] Furthermore, the buffer member 201 includes a buffer zone 203, a transition zone 204 and a limiting zone 205. The transition zone 204 is disposed obliquely between the buffer zone 203 and the limiting zone 205, and the limiting zone 205 gradually narrows in a curve to achieve the buffering function and reduce the collision between connected objects and the noise generated by the collision.

[0022] Additionally, one side of the second limiting protrusion 306 has a circular arc chamfer 310, and an inclined platform 311 is provided on the other side; the outer side surface of the second limiting protrusion 306 is in clearance fit with the buffer zone 203, in transition fit with the transition zone 204, and in interference fit with the limiting zone 205.

[0023] Furthermore, gaskets 6 are respectively provided between the upright column 4 and the upper cover vane 101 and the lower cover vane 102, and a seal 7 is provided between the upper cover vane 101 and the connecting shaft 3 to improve the sealing effect between the components.

[0024] Additionally, the connecting member 202 includes a plurality of buffer protrusions 8, and the buffer protrusions 8 are in the shape of a frustum of a pyramid, which ensures the connection strength while avoiding excessive friction. Further, the chassis 5 is provided with a connection end 9, and the connection end 9 includes a plurality of connection threaded holes. In this embodiment, the number of connection threaded holes is 2. Specific Embodiment 2 As Figure 13-15 shown, the difference between this embodiment and Embodiment 1 lies in the fixing and connection methods of the buffer connection hinge. The buffer member 201 is disposed in the inner cavity of the fixed seat 2, and the fixed seat 2 is disposed on the first connection portion 302 of the connection shaft 3. The buffer connection hinge is connected to the rotating member through the fixing of the fixed seat 2 and the second connection portion 303 of the connection shaft 3, driving the first connection portion 302 of the connection shaft 3 to rotate. The second limiting boss 306 disposed on the first connection portion 302 rotates, successively passing through the buffer zone 203, the transition zone 204, and the limiting zone 205. The gap between the second limiting boss 306 and the buffer member 201 gradually becomes smaller until the generated frictional force is greater than the rotating force of the rotating member, realizing the buffer function of the rotating member, reducing the collision between the connected objects and the noise generated by the collision, and improving the service life of the toilet lid and the user experience.

[0026] Working principle: On both sides of one end of the toilet cover plate, buffer connection hinges are symmetrically provided. The buffer connection hinge includes a vane 1, a buffer member 201, a connection shaft 3, a column 4, and a chassis 5. The connection shaft 3 is disposed at one end of the column 4, and the chassis 5 is disposed at the other end of the column 4; the connection shaft 3 includes a fixing portion 301, a first connection portion 302, and a second connection portion 303. A second limiting boss 306 is provided on the outer side wall of the first connection portion 302. The lower cover vane 102 is disposed on the second connection portion 303, and a second buffer member 202 is provided between the lower cover vane 102 and the second connection portion 303, enabling the lower cover vane 102 to rotate around the second connection portion 303; The upper cover vane 101 is disposed on the first connection portion 302. A plurality of limiting blocks 307 are provided on the inner side wall of the hollow inner cavity. Adjacent limiting blocks 307 form an installation groove 308 for the first buffer member 201. A connection column 309 for installing and fixing the upper cover vane 101 is further provided at the center of the hollow inner cavity. The first buffer member 201 is disposed in the installation groove 308; The first buffer member 201 includes a buffer zone 203, a transition zone 204, and a limiting zone 205. The transition zone 204 is disposed in an inclined plane between the buffer zone 203 and the limiting zone 205. The limiting zone 205 gradually shrinks in a curve. When the upper cover vane 101 rotates, it drives the buffer member 201 to rotate, so that the buffer zone 203, the transition zone 204, and the limiting zone 205 successively pass through the second limiting boss 306. The gap between the buffer member 201 and the second limiting boss 306 changes from large to small, and the frictional force generated by the extrusion deformation of the buffer member 201 and the second limiting boss 306 changes from none to having a value until the frictional force can stop the upper cover vane 101; Implement the buffering function of the upper cover plate to reduce the collision between connected objects and the noise generated by the collision, and improve the service life of the toilet lid and the user experience.

[0027] The above has described the embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and deformations made to these embodiments still fall within the protection scope of the present invention.
