[0017] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0018] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] In addition, in the description of the present invention, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "set", "socket", "connect", "penetrate", "plug in" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; 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 the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 and Figure 2 A spring tensioning guide structure for a glass lifter is shown, comprising a motor base plate 1, wherein the motor base plate 1 has a cable hole 101 set at an angle, and both ends of the cable hole 101 are processed to form guide holes 102, and a tensioning guide 2 is slidably fitted in the guide hole 102, and the tensioning guide 2 slides axially along the guide hole 102, and an inner hole 291 for passing the cable is provided inside the tensioning guide 2, and a spring 3 is fitted between the tensioning guide 2 and the motor base plate 1.

[0023] In this technical solution, through the directional cooperation between the guide hole 102 and the tensioning guide 2, the tensioning guide 2 can only slide along the axial direction of the guide hole 102, but cannot rotate coaxially along the guide hole 102, thereby avoiding the abnormal noise problem caused by the rotation of the tensioning guide 2.

[0024] See also Figure 4 As shown, the end of the inner hole 291 facing the cable hole 101 is processed to form a tapered hole 211 , and the diameter of the tapered hole 211 gradually increases toward the cable hole 101 .

[0025] The tapered hole 211 can accommodate a larger swing of the cable and reduce abnormal noise caused by friction.

[0026] See also Figure 2 As shown, the guide hole 102 is a square hole, and the tensioning guide member 2 fits into the guide hole 102 .

[0027] This technical means upgrades the guide circular hole in the prior art into a square hole. This small change can solve the problem of abnormal rotation noise of the tensioning guide 2, and the upgrade cost is lower.

[0028] See also Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the tensioning guide 2 includes a guide portion 201, one end of the guide portion 201 is inserted into the guide hole 102 and slides along the guide hole 102, the end of the guide portion 201 away from the guide hole 102 is processed to form a large diameter portion 202, the large diameter portion 202 is transitionally matched with the spring 3, and the end of the large diameter portion 202 away from the guide portion 201 is provided with a limiting portion 203, and the spring 3 is limited by the limiting portion 203.

[0029] In the above technical solution, the guide part 201 fits the guide hole 102, and the guide part 201 and the guide hole 102 are in plane contact, so that the guide part 201 can only slide along the axial direction of the guide hole 102, but cannot rotate. It is ensured that the spring will not rotate during the expansion and tensioning process, and the problem of abnormal sound caused by the spring rotation is solved.

[0030] See also Figure 1 and Figure 3 As shown, a connecting rib 221 is provided between the limiting portion 203 and the large diameter portion 202 , and the connecting rib 221 is interference fit with the spring 3 .

[0031] In this technical solution, the large diameter portion 202 of the limiting part is transitionally matched with the spring 3. During assembly, the connecting rib 221 is inserted into the spring 3 and has an interference fit with the spring 3, which can effectively prevent the spring 3 from loosening, and the entire device is more stable.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
