[0040] See Figure 1 , Figure 1 Fig. shows an exploded view of the structure of an embodiment of a sliding door guiding assembly provided by the present invention. The sliding door guiding assembly mainly includes a base, an adjusting unit, an elastic unit 20, a first guiding gasket 31, a second guiding gasket 32, and a fixing screw 50.

[0041] Wherein, the base is provided with a first guiding groove 14 for the sliding door to slide along a first direction and a second guiding groove arranged parallel to the first guiding groove 14. Specifically, the base includes a seat body 10 and a fixing member 15.

[0042] Refer to Figure 2 , the seat body 10 includes a seat body bottom wall 13. On both sides of the seat body bottom wall 13 in the first direction, first groove walls 12 and second groove walls with the same structure extend upward. The first groove wall 12 and the second groove wall cooperate to form a groove-like structure extending along the first direction. The seat body bottom wall 13 protrudingly provides an intermediate seat body 11 extending along the first direction at the middle position of the groove-like structure. The intermediate seat body 11 divides the groove-like structure into the above-mentioned first guiding groove 14 and second guiding groove, and it has two side walls respectively facing the first guiding groove 14 and the second guiding groove; at the same time, the seat body bottom wall 13 is provided with screw mounting holes 133 at the front and rear ends of the intermediate seat body 11 along the first direction. The screw mounting holes 133 can cooperate with the fixing screw 50 to fix the seat body 10 on the door frame of the sliding door device, thereby fixedly installing the sliding door guiding assembly on the sliding door device.

[0043] The seat body bottom wall 13 is also provided with an installation cavity inlet 132 at a position corresponding to the intermediate seat body 11. The interior of the intermediate seat body 11 is hollow to form a downward-opening installation cavity. At the same time, both side walls of the intermediate seat body 11 are provided with a receiving cavity opening 111 respectively facing the first guiding groove 14 and the second guiding groove. First clamping grooves 112 and second clamping grooves 113 are respectively arranged at the front and rear positions of the receiving cavity opening 111 of the intermediate seat body 11 along the first direction. The first clamping grooves 112 and the second clamping grooves 113 are both symmetrically arranged on the two side walls of the intermediate seat body 11 along the horizontal direction and perpendicular to the second direction of the first direction and penetrate the two side walls; a through hole 114 is also provided at the end of the intermediate seat body 11 far from the first clamping groove 112. The through hole 114 penetrates the end of the intermediate seat body 11 along the first direction. At the same time, refer to Figure 5 Installation relief grooves 115 extending in a third direction perpendicular to the first direction and the second direction are provided on the cavity wall of the installation cavity of the intermediate seat body 11 corresponding to the first clamping groove 112 and the second clamping groove 113. In addition, a positioning protrusion is provided at the top wall position of the installation cavity.

[0044] Refer to Figure 6 , on the first groove wall 12 and the second groove wall, there are provided guide gasket mounting portions 121 for mounting the first guide gasket 31 and the second guide gasket 32, and two guide gasket mounting portions 121 are arranged along the first direction on each groove wall. The first guide gasket 31 is mounted on the guide gasket mounting portion 121 on the first groove wall 12, and the second guide gasket 32 is mounted on the guide gasket mounting portion 121 on the second groove wall. Here, the structure on the first groove wall 12 is taken as an example for illustration. At the position of the seat body bottom wall 13 corresponding to the guide gasket mounting portion 121, there is provided an insertion inlet 131. The first guide gasket 31 can be inserted into the guide gasket mounting portion 121 from the insertion inlet 131. The front and rear positions of the guide gasket mounting portion 121 in the first direction are provided with a first mounting groove 122 extending along the third direction. Here, the first groove wall 12 is a hollow structure inside, and an inner cavity wall 1221 facing the outside of the seat body 10 is formed on its inner side. At the same time, a protrusion 1222 is provided on the cavity wall of its inner side facing the inside of the seat body 10. The protrusion 1222 and the opposite inner cavity wall 1221 cooperate to form the first mounting groove 122. The first guide gasket 31 can be inserted into the first mounting groove 122 and is fixed by friction. Correspondingly, a second mounting groove having the same structure as the first mounting groove 122 is also provided on the second groove wall, which will not be elaborated here.

[0045] After the first guide gasket 31 and the second guide gasket 32 are mounted on the seat body 10, since the first guide gasket 31 and the second guide gasket 32 are themselves designed as structures protruding towards one side, the protruding structures will protrude towards the position where the intermediate seat body 11 is located out of the first guide groove 14 and the second guide groove. Or, in other embodiments, when the first guide gasket 31 and the second guide gasket 32 are inserted into the guide gasket mounting portion 121, due to the elasticity of the first guide gasket 31 and the second guide gasket 32, the two will be squeezed by the force in the first direction, and thus protrude towards the intermediate seat body 11 out of the first guide groove 14 and the second guide groove respectively. This protruding structure can reduce the friction on the sliding door and improve the smoothness of the sliding door passing through.

[0046] At both ends of the first groove wall 12 and the second groove wall along the first direction, there are also provided groove wall guide inclined surfaces 123 extending along the first direction and inclined towards the intermediate seat body 11. At both ends of the two sides of the intermediate seat body 11 in the second direction along the first direction, there are provided intermediate seat body guide inclined surfaces 116 extending along the first direction and inclined towards the first groove wall 12 and the second groove wall respectively. Specifically, refer to Figure 6, taking the groove wall guiding inclined surface 123 at the first guiding groove 14 and the intermediate seat body guiding inclined surface 116 as examples, at the front and rear positions of the first guiding groove 14 along the first direction, a total of four guiding inclined surfaces are formed, two of which are groove wall guiding inclined surfaces 123 and two are intermediate seat body guiding inclined surfaces 116. The groove wall guiding inclined surface 123 and the intermediate seat body guiding inclined surface 116 at the same end make the first guiding groove 14 form a trumpet-shaped opening that opens outward. Such a trumpet-shaped opening can facilitate guiding the sliding door into the first guiding groove 14.

[0047] The base further includes a fixing member 15. Refer to Figure 3 , the fixing member 15 can be regarded as including a main body. On the main body, a fixing member connecting column 151 extending along the first direction is provided. At the end of the free end of the fixing member connecting column 151, a threaded hole 154 is recessed along the first direction. At the same time, a fixing member positioning hole 152 is provided upward on the main body of the fixing member 15. The fixing member positioning hole 152 can cooperate with the positioning protrusion provided in the installation cavity of the intermediate seat body 11 to limit the movement of the fixing member 15. First clamping blocks 153 are further provided on both sides of the main body of the fixing member 15 in the second direction. The first clamping blocks 153 can be clamped into the first clamping groove 112 along the installation relief groove 115 corresponding to the first clamping groove 112 and are limited and fixed by the first clamping groove 112.

[0048] The fixing member 15 and the intermediate seat body 11 cooperate to form an intermediate seat. The intermediate seat is located between the first guiding groove 14 and the second guiding groove, and the adjusting unit is fixedly connected to the intermediate seat with adjustable position. At the same time, the part of the installation cavity between the fixing member 15 and the through hole 114 forms a receiving cavity. The receiving cavity opening 111 is provided on the wall of the receiving cavity, and the receiving cavity is used to accommodate the elastic unit 20.

[0049] The adjusting unit includes a holding member 42 and an adjusting member 41. Refer to Figure 3 , the holding member 42 can be regarded as including a holding member main body. On the holding member main body, a holding member connecting column 421 extending along the first direction is provided. At the same time, a holding member communication hole 422 penetrating the main body of the holding member 42 and the connecting column 421 along the first direction is provided on the holding member 42. Second clamping blocks 423 are provided on both sides of the holding member main body in the second direction. The second clamping blocks 423 can be clamped into the second clamping groove 113 along the installation relief groove 115 corresponding to the second clamping groove 113, and the length of the second clamping groove 113 in the first direction is greater than the width of the second clamping block 423 in the first direction, which enables the holding member 42 to slide along the second clamping groove 113 in the first direction. The adjusting member 41 is a long rod screw, which can pass through the holding member communication hole 422 on the holding member 42, and its end cap can abut against the holding member 42.

[0050] The elastic unit 20 is disposed between the base and the adjusting unit along the first direction, and is adapted to protrude from the first guiding groove 14 and the second guiding groove along the second direction. Specifically, it is an elastic ring, which can be regarded as having two symmetric ends in its radial direction, and through holes are provided at these two ends, through which the connecting posts 151 of the fixing member and the connecting posts 421 of the abutting member can pass. In other embodiments, the elastic unit 20 can also be one or more elastic strips, which can extend along the first direction and be disposed in the accommodating cavity.

[0051] After the connecting posts 151 of the fixing member and the connecting posts 421 of the abutting member pass through the two ends of the elastic unit 20, the threaded holes 154 and the through holes 422 of the abutting member are aligned, and the adjusting member 41 can be screwed into the threaded holes 154 after passing through the through holes 422 of the abutting member, so that the adjusting unit is fixedly connected to the base in a position adjustable in the first direction.

[0052] During installation, first install the fixing member 15 and the abutting member 42 on the elastic unit 20, and then pass the adjusting member 41 through the abutting member 42 and screw it onto the fixing member 15. Then install the assembled components from the installation cavity entrance 132 into the installation cavity of the intermediate seat body 11. At this time, the part of the installation cavity between the fixing member 15 and the through hole 114 forms an accommodating cavity for installing the adjusting unit and the elastic unit 20, so that the fixing member 15 and the abutting member 42 are clamped on the intermediate seat body 11, and both sides of the elastic unit 20 in the second direction will be exposed from the opening 111 of the accommodating cavity. Then cover the decorative cover 60 on the intermediate seat body 11, and then install the sliding door guiding assembly on the door frame of the sliding door device through the fixing screw 50.

[0053] During use, a screwdriver can be passed through the through hole 114 to rotate the adjusting member 41, so as to adjust the distance between the fixing member 15 and the abutting member 42, and further make the abutting member 42 push against the elastic unit 20 to deform it, so as to achieve the purpose of adjusting the protruding degree of the elastic unit 20 towards the first guiding groove 14 and the second guiding groove.

[0054] In addition, the present invention also provides a sliding door device, which includes a door frame and a sliding door, and of course also includes other components such as a pulley assembly, which will not be described in detail here. The sliding door device mainly further includes the sliding door guiding assembly provided in the above embodiment. The sliding door guiding assembly is fixedly installed on the door frame through the fixing screw 50, preferably fixedly installed at the bottom position of the door frame, and limits and guides the sliding direction of the sliding door when the sliding door slides.

[0055] A sliding door guiding component and a sliding door provided by the present invention can, through the change in the position of the adjusting unit in the first direction, cause the elastic unit 20 to change the degree of protruding towards the first guiding groove 14 under the action of the adjusting unit, so that the sliding door guiding component can be adapted to sliding doors of different thicknesses, without the need to re-manufacture the sliding door guiding component by opening a new mold for sliding doors of different thicknesses, thereby reducing the production and manufacturing costs.
