[0023] 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.

[0024] like Figure 1 A window lifter sliding frame spring limiting structure shown in the figure comprises a sliding frame body 1, a spring groove 101 for installing a spring is arranged on the inner side of the sliding frame body 1, a bottom bracket 102 for supporting the spring is arranged at the bottom of the spring groove 101, through grooves 103 are arranged at both ends of the spring groove 101, the groove width of the through groove 103 is smaller than the groove width of the spring groove 101, and the groove width of the through groove 103 is smaller than the diameter of the installed spring, and limiting protrusions 2 for limiting the spring are arranged on the inner walls on both sides of the spring groove 101.

[0025] See also Figure 3 As shown, the upper and lower surfaces of the limiting protrusion 2 are both arc-shaped surfaces 21, and the arc-shaped surface 21 fits the outer surface of the spring.

[0026] The design of the arc surface 21 can increase the contact area with the spring, making the fixation of the spring more stable.

[0027] See also Figure 1 As shown, a filling port 121 for filling a spring is provided at the upper end of the spring slot 101 , and the length of the filling port 121 is smaller than the length of the spring slot 101 . The spring is loaded from the filling port 121 after being compressed.

[0029] See also Figure 3 As shown, the through groove 103 is a U-shaped groove, and the axis of the bottom arc surface of the through groove 103 is coaxial with the axis of the arc surface 21. When the spring is limited by the arc surface 21 below, the limited spring is coaxial with the bottom arc surface of the U-shaped groove.

[0030] This technical solution can ensure coaxiality and further reduce abnormal noise during operation.

[0031] The sliding frame body 1 and the limiting protrusion 2 are an integrated structure.

[0032] The one-piece structure is easy to shape and has high structural strength.

[0033] See also Figure 2 As shown, the bottom bracket 102 includes a transverse portion 122 and a longitudinal portion 123 , the transverse portion 122 and the longitudinal portion 123 are vertically staggered, and the transverse portion 122 and the longitudinal portion 123 are an integrated structure with the sliding frame body 1 .

[0034] The combination of the transverse portion 122 and the longitudinal portion 123 can provide stable support for the spring.
