[0023] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Embodiment 1:

[0025] This embodiment provides a sill assembly structure.

[0026] like Figure 1 and 2 The assembly structure of a sill for a car shown in the figure is composed of a car with a door opening on the front wall, a car door arranged at the door opening, and a sill 6 arranged at the bottom of the door opening and guiding the car door to open and close. The car includes a bottom plate 1, a top plate 2, a side plate 3, and a column 4. The column 4 vertically spans between the two ends of the front edge of the bottom plate 1 and the top plate 2 and encloses the door opening. A height-adjustable bracket 5 is provided on the front wall of the bottom plate 1. The top surface of the bracket 5 is provided with a supporting surface, and the sill 6 is installed on the supporting surface. The sill 6 is installed on the front wall of the bottom plate 1 through the bracket 5. The sill 6 is installed on the front wall of the bottom plate 1 through the bracket 5. The bottom plates 1 of various types of cars can be used universally by unifying the installation structure of the sill 6, and the production, assembly and maintenance are facilitated by improving the adaptability of the bottom plate 1. The assembly is also facilitated by simplifying the construction to improve the user experience. In addition, the height of the top surface of the sill 6 is adjusted by adjusting the height of the bracket 5, so that the sill 6 can be adjusted according to the thickness of the decorative panel above the base plate 1, ensuring that the top surface of the sill 6 is flush with the top surface of the decorative panel, preventing passengers from stumbling when entering and exiting the car, thereby improving safety in use.

[0027] In this embodiment, a guide groove 9 is provided on the top surface of the sill 6, which is suitable for a center-split double-door elevator car, and the guide groove 9 is used to guide the mirror-image opening and closing of the two car doors.

[0028] During installation, first, the bracket 5 is fixed to the front wall of the bottom plate 1 by fasteners passing through the long holes 7, and the front bracket 5 can be raised and lowered; then, the sill 6 is installed on the supporting surface of the top surface of the bracket 5 and fixed by fasteners; finally, the bottom end surface of the column 4 overlaps the top front edge of the bracket 5 and is fixed by fasteners. The sill 6 is installed through the above steps, so that the sill 6 is installed on the bottom plate 1 through the bracket 5, which can not only improve the application range of the bottom plate 1 through a unified structure, but also meet the use requirements of different types of cars by replacing the sill 6 on the bracket 5, and can also adjust the height of the top surface of the sill 6 by adjusting the height of the bracket 5, thereby ensuring that the top surface of the sill 6 can be set flush with the top surface of the decorative board.

[0029] In this embodiment, a decorative board is laid on the bottom plate 1, and the height of the sill 6 is adjusted by the bracket 5 so that the top surface of the sill 6 is flush with the top surface of the decorative board. The decorative board can be selected in any thickness as needed, which increases the optional range of the decorative board and increases the diversity of decoration. When in use, the height of the top surface of the sill 6 is first determined according to the thickness of the decorative board, and then the height of the bracket 5 is adjusted to make the top surface of the sill 6 reach a preset height, and finally ensure that the top surface of the sill 6 is flush with the top surface of the decorative board, effectively preventing passengers from stumbling when entering and exiting the car, and ensuring safety in use.

[0030] In this embodiment, the rear wall of the bracket 5 facing the base plate 1 is provided with a vertically opened long hole 7, and the front wall of the base plate 1 is provided with a mounting hole. The fastener passes through the long hole 7 and is fixedly locked with the corresponding mounting hole, so that the height of the bracket 5 can be adjusted. The bracket 5 is convenient to lift and lower by loosening the fastener, and the fastener is tightened to achieve the fixation after the height of the bracket 5 is adjusted to the right position, so as to ensure the supporting reliability of the bracket 5. There are multiple long holes 7, and they are arranged horizontally along the rear wall of the bracket 5. By increasing the number of corresponding fasteners, the connection reliability between the bracket 5 and the base plate 1 is improved, and the bracket 5 is prevented from deviating downward after long-term use. By providing multiple long holes 7, the number of connection points between the bracket 5 and the base plate 1 is increased, thereby ensuring that the bracket 5 and the sill 6 maintain a horizontal posture.

[0031] In this embodiment, the column 4 is fixed to the bottom plate 1 through the bracket 5, and the bottom end surface of the column 4 is fixedly connected to the front edge of the support. The sill 6 is arranged close to the column 4 in a front-to-back offset manner. Since only one guide groove 9 is provided on the sill 6, the width of the sill 6 is relatively narrow, and the space below the column 4 does not need to be occupied while meeting the structural strength requirements, ensuring that the sill 6 and the column 4 can be independently assembled and fixed to the bracket 5, thereby improving the convenience of assembly.

[0032] In this embodiment, the top front edge of the bracket 5 is provided with a fixing hole 8, and the bottom end of the column 4 is fixed to the bracket 5 by a fastener passing through the fixing hole 8. The bracket 5 has an integral plate bent into an L shape (such as Figure 3As shown in the figure, it includes an upper part and a side part. The front edge of the upper part is provided with the fixing hole 8. The fastener passes through the bottom end surface of the column 4 and the fixing hole 8 from top to bottom and is screwed and locked with the corresponding nut, which not only ensures the tight connection between the column 4 and the bracket 5, but also ensures the relative posture fixation of the two by increasing the contact area, and ensures that the column 4 is always vertically arranged on the top surface of the bracket 5. In addition, the long hole 7 is opened on the side part, and a reinforcing plate is also provided between the upper part and the side part, effectively improving the anti-deformation performance of the bracket 5.

[0033] In this embodiment, the bottom surface of the sill 6 is provided with a lapping surface, and the top surface is provided with a guiding groove 9 arranged along the opening and closing path of the car door. The sill 6 is lapped on the supporting surface from top to bottom through the lapping surface and is fixedly connected by fasteners, so that the relative position between the guiding groove 9 and the door opening is fixed and the opening and closing switching of the car door is guided.

[0034] In this embodiment, the sill 6 is a split structure, including a U-shaped base 10 with an upward opening and a guiding strip 11 arranged in the base 10 (as Figure 4 shown). The guiding strip 11 is provided with the guiding groove 9 exposed through the opening. The two side edges of the guiding strip 11 are sleeved on the corresponding side edges of the opening through the sliding grooves 12. By providing guiding strips 11 with various cross-sectional profiles of the guiding groove 9 cavity to meet the matching requirements of various car doors, it is convenient for production and assembly by sharing the base 10, reduces the processing cost by reducing the types of parts, improves the convenience of assembly and maintenance, and also meets the usage requirements of various types of car doors by configuring guiding strips 11 with different sizes of guiding grooves 9. The opposite side edges of the opening are bent to form flanges, and the sliding grooves 12 are horizontally sleeved on the corresponding flanges, which not only uses the flanges to support the guiding strip 11, but also plays a role in limiting the guiding strip 11 in the width direction to prevent the sliding groove 12 from detaching from the flange along the width direction of the guiding groove 9.

[0035] Embodiment 2:

[0036] Compared with Embodiment 1, this embodiment provides another sill assembly structure.

[0037] As Figure 5 and 6 shown, the top surface of the sill 6 is provided with two mutually parallel guiding grooves 9. The front edge of the sill 6 is arranged between the bottom end surface of the column 4 and the supporting surface. The front edge of the sill 6 is provided with a perforation for the fastener to pass through. The fastener passes through the bottom end surface of the column 4, the perforation and the bracket 5 from top to bottom and is screwed and locked. It is applicable to a four-panel center-opening car. Two guiding grooves 9 are used to respectively guide two groups of car doors to open and close in a mirror image. The vertical projection of the guiding groove 9 is misaligned with the vertical projection of the column 4 to ensure that the guiding groove 9 is upwardly exposed and provides a moving space for the car door. The front part of the sill 6 is arranged between the column 4 and the bracket 5, and the front-to-back dimension of the sill 6 is increased by occupying the space below the column 4, thereby improving the structural strength.

[0038] In this embodiment, the sill 6 is an integrated structure (eg Figure 7 As shown in the figure, the area where the rear part of the top surface of the sill 6 and the vertical projection of the column 4 are misaligned is recessed downward to form the guide groove 9. During installation, the sill 6 is first installed on the supporting surface of the bracket 5, and then the bottom end of the column 4 is overlapped on the front edge of the supporting surface and fixedly locked by fasteners, so as to effectively utilize the space between the column 4 and the bracket 5, and improve its anti-deformation performance by increasing the width of the sill 6. The rear part of the top surface of the sill 6 is recessed to form the guide groove 9, which not only ensures the structural reliability, but also improves the anti-deformation performance by providing the guide groove 9.

[0039] The other structures and effects of the sill assembly structure described in this embodiment are consistent with those in the first embodiment and will not be described in detail.
