Abstract
Description
Technical Field
[0001] The utility model relates to a motor seat plate structure for a window regulator. Background Art
[0002] The motor seat plate is an important component for installing the motor of the window regulator in the vehicle. The vehicle door is divided into a left door and a right door. In the prior art, the motor seat plate is separately molded according to the left and right doors and then separately injection-molded, which requires two sets of molds. The development cost of the molds is relatively high, and the two-sided motor seat plates are independently designed, resulting in a relatively high design cost.
[0003] Based on the above problems, we have designed a motor seat plate structure for a window regulator that adopts a symmetrical design and only requires one set of molds. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a motor seat plate structure for a window regulator that adopts a symmetrical design and only requires one set of molds.
[0005] To solve the above problems, the utility model adopts the following technical solutions:
[0006] A motor seat plate structure for a window regulator includes a seat plate body. A motor installation opening for installing a window regulator motor is provided in the middle of the seat plate body. Three motor installation hole positions are annularly arranged outside the motor installation opening. The seat plate body is a symmetrical structure. The seat plate body takes the diameter line of the motor installation opening as the symmetry center line, and the three motor installation hole positions are symmetrically arranged with the diameter line as the symmetry center line. On the plate surface of the seat plate body, three slideway installation hole positions are provided below the motor installation opening, and the slideway installation hole positions are also symmetrically arranged with the diameter line as the symmetry center line. On the plate surface of the seat plate body, a fixed seat for connecting the vehicle door is provided at the upper left or upper right of the motor installation opening; a cable groove communicating with the motor installation opening is provided on the plate surface of the seat plate body.
[0007] Preferably, two cable grooves are provided with the diameter line as the symmetry center line. Both of the two cable grooves communicate with the motor installation opening, and an arc transition is provided between the two cable grooves.
[0008] Preferably, the cable groove is a circular groove.
[0009] Preferably, an opening groove is provided at the upper end of the cable groove, and the groove width of the opening groove is smaller than the diameter of the cable groove.
[0010] Preferably, a wire laying plate is provided at the bottom of the cable groove. The wire laying plate has a U-shaped wire laying opening, and the cable is positioned through the wire laying opening.
[0011] Preferably, a positioning tube for positioning the motor shaft is provided at the axis of the motor mounting opening.
[0012] Preferably, on the inner bottom of the motor mounting opening, a convex ring is provided outside the positioning tube. Spherical concave holes are annularly distributed on the surface of the convex ring, and the convex ring is coaxial with the positioning tube.
[0013] The beneficial effects of the present utility model are as follows:
[0014] In this device, the motor seat plate adopts a symmetrical structural design. Therefore, the shapes and sizes of the motor seat plates of the left and right doors are the same. The difference lies in the positions of the fixed seats. Therefore, by using an independent set of molds and cooperating with an insert that can change positions left and right, the positions of the fixed seats on the injection-molded motor seat plates can be changed. The injection molding of the motor seat plates on the left and right door panels can be completed through a set of molds, reducing the development and design costs and being suitable for popularization and use.

[0024] Refer to Figure 1 and Figure 2 A motor seat plate structure for a window regulator shown in the figure, which includes a seat plate body 1. A motor mounting opening 2 for mounting a window regulator motor is provided in the middle of the seat plate body 1. Three motor mounting holes 3 are annularly arranged outside the motor mounting opening 2. The seat plate body 1 is a symmetric structure. The seat plate body 1 takes the diameter line A of the motor mounting opening 2 as the symmetric center line. The three motor mounting holes 3 are symmetrically arranged with the diameter line A as the symmetric center line. On the plate surface of the seat plate body 1, three slideway mounting holes 4 are provided below the motor mounting opening 2. The slideway mounting holes 4 are also symmetrically arranged with the diameter line A as the symmetric center line. On the plate surface of the seat plate body 1, a fixing seat 5 for connecting to the vehicle door is provided at the upper left or upper right of the motor mounting opening 2. A cable groove 6 communicating with the motor mounting opening 2 is provided on the plate surface of the seat plate body 1.
[0025] In the above technical solution, the seat plate body 1 has a symmetric structure with the diameter line A as the symmetric center line, so that the seat plate body 1 can adapt to the doors on both the left and right sides. The only difference lies in the different positions of the fixing seat 5. When the seat plate body 1 is located at the left door, the fixing seat 5 is located on the left side of the diameter line A. When the seat plate body 1 is located at the right door, the fixing seat 5 is located on the right side of the diameter line A. To achieve the above purpose, the mold for injecting the seat plate body 1 is designed as a mold with inserts. By only changing the position of the inserts in the mold, the injection molding of the seat plate body 1 on both the left and right sides can be completed with one set of molds. The function of the inserts is to form the fixing part 5.
[0026] Therefore, in this device, by adopting the symmetrically designed seat plate body 1, the originally required two sets of seat plate injection molds for the left and right sides can be upgraded to only one set of injection molds with inserts, reducing the mold development cost.
[0027] Refer to Figure 2 As shown, there are two cable grooves 6 arranged with the diameter line A as the symmetric center line. Both of the two cable grooves 6 communicate with the motor mounting opening 2, and there is an arc transition between the two cable grooves 6.
[0028] In the above technical solution, the cable passes through the seat plate body 1 through the cable grooves 6 on both sides, and there is an arc transition between the two cable grooves 6 to avoid abrasion of the cable.
[0029] The cable groove is a circular groove.
[0030] An opening groove 61 is provided at the upper end of the cable groove 6, and the groove width of the opening groove 61 is smaller than the diameter of the cable groove 6.
[0031] The setting of the opening groove 61 facilitates the assembly of the cable. The diameter of the cable is slightly smaller than the groove width of the opening groove 61. When the cable is inserted, it has a clearance fit with the cable groove 6 to reduce friction.
[0032] Refer to Figure 3 As shown, a cable support plate 62 is provided at the bottom of the cable groove 6. The cable support plate 62 has a U-shaped cable support opening 63, and the cable is positioned through the cable support opening.
[0033] In the above technical solution, by overhead the cable through the cable support plate 62, the contact between the cable and the groove wall of the cable groove 6 can be reduced, and the heat generated by friction can be reduced.
[0034] Preferably, a positioning tube 21 for positioning the motor shaft is provided at the axis center of the motor mounting opening 2.
[0035] The positioning tube 21 is used to position the motor shaft to make the motor shaft more stable during rotation. During installation, a bearing can be installed between the motor shaft and the positioning tube 21 to further increase the stability of the motor shaft.
[0036] Refer to Figure 2 As shown, on the inner bottom of the motor mounting port 2, a convex ring 22 is provided outside the positioning tube 21. Spherical concave holes 23 are annularly distributed on the surface of the convex ring 22. The convex ring 22 is coaxial with the positioning tube 21.
[0037] During use, a cable pulley needs to be installed on the motor shaft. The cable bypasses the cable pulley, and the rotation of the cable pulley drives the sliding of the cable. By placing a ball in the spherical concave hole 23 and making the ball contact the end face of the cable pulley, the stability of the cable pulley during rotation can be increased.
