Description

Technical Field

[0001] The utility model relates to the technical field of lifters, in particular to a rotary wheel mounting structure and a lifter. Background Art

[0002] With the development of the automotive industry, the integration of various functional and safety components within vehicle doors has taken up space within the door cavity, resulting in increasingly tight space for mounting points on integrated lifters within the door cavity. The existing solution involves inserting a pivot screw through the door panel and securing it with a nut. This solution requires a significant amount of space within the vehicle and the large number of structural parts makes installation inconvenient. Utility Model Content

[0003] In view of the deficiencies in the prior art, the first object of the present invention is to provide a wheel installation structure which has a compact structure, is easy to install and has a stable and reliable connection.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] During assembly, the wheel is mounted on the base, and the gasket is installed on the connector. External force causes one end of the connector to deform, pressing the gasket against the base. The two ends of the connector are then locked into position with the two ends of the base, completing the assembly of the wheel and base. This mounting structure provides a stable and reliable connection while also occupying less space, being compact, easy to manufacture, highly versatile, and low in cost.

[0008] Furthermore, the connecting member includes a rivet and is provided with an internal thread, and the connecting member is rotatably riveted on the base.

[0009] Furthermore, the limiting portion includes a flange provided at one end of the connecting member.

[0010] Furthermore, a slot is provided at one end of the connecting member away from the limiting portion, and the gasket is sleeved on the slot.

[0011] Furthermore, a gap is provided between the gasket and the slot.

[0012] Furthermore, the connecting piece is provided with an anti-rotation module, and the base is provided with a groove matching the anti-rotation module.

[0013] Furthermore, the anti-rotation module includes a polygonal protrusion.

[0014] Furthermore, the connecting piece and the base are injection molded

[0015] Another object of the present invention is to provide a lifter, comprising any one of the above-mentioned rotating wheel mounting structures, wherein the rotating wheel mounting structure is arranged at the upper end of the guide rail module of the lifter.

[0016] The wheel mounting structure of the lifter is compact, occupies little space, is lightweight, has high versatility, and is low in cost. Furthermore, the wheel is easy to assemble and has a secure connection. Especially when the wheel mounting structure is positioned at the upper end of the lifter guide rail module, its compact structure makes assembly even easier. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; the structures described in various embodiments can be freely combined without any conflict in structure or principle.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., etc., are used solely for distinction and description, and should not be construed as indicating or implying relative importance.

[0026] Below with reference to accompanying drawing some embodiment of the present utility model is described:

[0027] like Figure 1 As shown, the present invention proposes a wheel mounting structure, comprising: a base 1, a connector 2, and a gasket 3, wherein the base 1 is provided with a cylinder, which passes through the center of the wheel 4 to support the wheel 4; the left and right ends of the connector 2 extend through holes, and the connector 2 can be injection molded with the base 1, or can be separated from the base 1 into two parts; the left end of the connector 2 is provided with a limiting portion 201, illustratively, the limiting portion 201 includes a flange structure provided at the left end of the connector 2, and the diameter of the flange is designed to be larger than the diameter of the hole; in this way, when the flange contacts the left side wall of the base 1, the base 1 plays a role in limiting the connector 2 from continuing to move right. A gasket 3 is installed on the right end of the connector 2, illustratively, in order to facilitate the disassembly and assembly of the gasket 3, a slot is designed at the right end of the connector 2, the gasket 3 is annular, and the inner wall of the gasket 3 is clamped on the slot, and the outer wall of the gasket 3 extends out of the slot. The right end of the connector 2 can be deformed to press the gasket 3 onto the base 1; illustratively, the connector 2 includes a rivet and is provided with an internal thread, so that the connector 2 can assemble the wheel 4 on the base 1 by rotating riveting.

[0028] Using this solution, during assembly, the right end of connector 2 is passed through the hole in base 1, then the runner 4 is mounted on the cylinder of base 1, and the gasket 3 is nested in the slot of connector 2. External force acts on connector 2, causing the right end of connector 2 to deform through rotary riveting, thereby pressing gasket 3 against base 1. At this point, the left and right ends of connector 2 are respectively positioned relative to the left and right ends of base 1, completing the assembly of runner 4 and base 1. This mounting structure not only provides a stable and reliable connection, but also has fewer components, occupies less space, is compact, has high versatility, and is low in cost.

[0029] Furthermore, if Figure 2 As shown, a gap A is provided between the gasket 3 and the slot; the gap is conducive to deformation of the connector 2 during riveting and facilitates assembly of the gasket 3.

[0030] As a preferred solution, Figure 3 and Figure 4 As shown, to prevent the connector 2 from rotating, an anti-rotation module 202 is provided on the connector 2. For example, the anti-rotation module 202 comprises a polygonal protrusion, and correspondingly, a groove is provided on the base 1 to match the anti-rotation module 202. After assembly, the protrusion is embedded in the groove to limit the rotation of the connector 2, thereby enhancing the stability of the installation structure.

[0031] The utility model also proposes a lifter, such as Figures 1 to 4 As shown, it is configured with any of the above-mentioned wheel mounting structures, especially configuring the mounting structure at the upper end position of the elevator guide rail module.

[0032] The installation structure of the wheel 4 of the lifter is compact, takes up little space, is lightweight, has high versatility, and is low in cost. Furthermore, the wheel 4 is easy to assemble and has a secure connection. In particular, when the installation structure of the wheel 4 is located at the upper end of the lifter guide rail module, its compact structure further facilitates assembly.
