DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides a driving end cover of a car starter motor, comprising a cover plate 1, two fastening screw holes 2 are formed through the upper surface of the cover plate 1 on both sides, and a mounting hole 3 is formed through the upper surface of the cover plate 1;

[0026] An axial hole 4 is formed through one side of the upper surface of the cover plate 1;

[0027] Two grooves 5 are formed on the upper surface of the cover plate 1 and located at the positions of the two fastening screw holes 2 .

[0028] The staff installs the cover plate 1 on the automobile starter motor by passing the fixing nail through the installation hole 3 and the fastening screw through the fastening screw hole 2. The driving shaft of the automobile motor passes through the shaft hole 4. By setting the groove 5, no material is saved and the material utilization rate is improved. In addition, by setting the groove 5, a convex rib structure is formed at the position of the fastening screw hole 2 of the cover plate 1, so that when the cover plate 1 is subjected to high stress and vibration during the starting process, its structural strength is high, thereby preventing the cover plate 1 from being deformed under the action of high stress and vibration.

[0029] In another embodiment of the utility model, a sealing sleeve 6 is fixedly mounted on the upper surface of the cover plate 1 , and a sealing ring 7 is arranged on the upper end of the sealing sleeve 6 .

[0030] A sealing ring 8 is fixedly mounted on the lower surface of the sealing ring 7 , and an annular sealing groove 9 is formed on the upper end surface of the sealing sleeve 6 , and the annular sealing groove 9 is interlaced with the sealing ring 8 .

[0031] A screw rod 10 is threadedly arranged on one side of the upper surface of the cover plate 1 , and a sealing ring 7 is threadedly arranged on one side of the shaft of the screw rod 10 .

[0032] A vertical pole 11 is fixedly mounted on the other side of the upper surface of the cover plate 1 , and a sealing ring 7 is slidably arranged on one side of the shaft of the vertical pole 11 .

[0033] The staff rotates the screw rod 10 to drive the sealing ring 7 down by screwing it in, so that the sealing ring 7 fits with the upper end of the sealing sleeve 6, and the sealing ring 8 is inserted in the annular sealing groove 9, thereby sealing the area around the shaft hole 4 to prevent external water vapor from entering the inside of the starter motor through the shaft hole 4, thereby avoiding affecting the normal use and life of the starter motor.

[0034] In another embodiment of the utility model, a slide groove 12 is provided on the upper surface of the cover plate 1 near the screw rod 10, a slider 13 is slidably arranged in the slide groove 12, and a tightening frame 14 is fixedly installed on the upper surface of the slider 13;
