Abstract
Description
Technical Field
[0001] The utility model relates to an improved invention, in particular to an improved invention of a waterproof turbine box cover. Background Art
[0002] The car window lifter includes a motor and a turbine box, which are installed in the car door. Rainwater will leak into the car door, so the waterproof performance needs to be improved. The traditional turbine box includes a turbine box body and a hood. The hood includes a cover body, and the cover body is provided with an axis hole, reinforcing ribs and three mounting feet. The cover body does not have waterproof performance. The setting of the reinforcing ribs and three mounting feet increases the material cost, and the three mounting feet make the assembly complicated. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a waterproof turbine box cover which has a simple structure and is easy to assemble.
[0004] In order to solve the above technical problems, the utility model is implemented by adopting the following technical solutions: the waterproof turbine box cover includes a cover body, which is characterized in that the cover body is integrally pressed, an axial hole is provided in the center of the cover body, an upper flange is provided on the outer peripheral edge of the cover body, and two centrally symmetrical mounting feet are provided on the upper flange. The cover body is also provided with an upwardly convex double step, the inner step is higher than the outer step, and a circle of punch points are evenly distributed on the surface of the outer step, and a waterproof sealing ring mounting groove is formed between the outer step and the upper flange.
[0005] The wall thickness of the cover body is 0.6 mm.
[0006] There are 12 punching points.
[0007] The punching point is convexly arranged.
[0008] R-angle transition is adopted between the upper flange, double steps, punching point and the cover body.
[0009] The beneficial effect of the utility model is an improved waterproof turbine box cover. The cover body adopts a 12-punch point design instead of a traditional reinforcement rib design, which reduces material costs. The cover body adopts a step design to place a waterproof sealing ring to ensure the waterproofness of the lifter motor. The cover is installed with a two-mounting foot riveted structure, which is more cost-effective than the traditional three-mounting foot installation structure and is simple to assemble, reducing assembly costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0011] Figure 1 It is a structural schematic diagram of the utility model.
[0012] Figure 2It is a structural sectional view of the utility model. DETAILED DESCRIPTION
[0013] The accompanying drawings show the structure of the utility model, and the following further describes its relevant details in conjunction with the accompanying drawings. Figure 1-2 The waterproof turbine box cover includes a cover body 1, which is integrally pressed and formed. An axial hole 2 is provided in the center of the cover body 1. An upper flange 3 is provided on the outer peripheral edge of the cover body 1. Two centrally symmetrical mounting feet 6 are provided on the upper flange 3, which are connected to the turbine box body by riveting, which is more cost-effective than the traditional three-mounting foot mounting structure. The cover body 1 is also provided with an upwardly convex double step, the inner step 4 is higher than the outer step 5, and a circle of punching points 7 are evenly distributed on the surface of the outer step 5, which replaces the design of traditional reinforcement ribs and reduces material costs. A waterproof sealing ring mounting groove 8 is formed between the outer step 5 and the upper flange 3 for mounting a waterproof sealing ring to ensure the waterproofness of the lifter motor.
[0014] When the utility model is used, the waterproof sealing ring is assembled in the waterproof sealing ring installation groove 8, the axial hole 2 of the cover body 1 is aligned with the turbine shaft, the sealing ring corresponds to the installation surface of the turbine box body, and then the upper flange 3 is riveted and connected to the turbine box body.
[0015] As a further improved specific implementation method, the wall thickness of the cover body 1 is 0.6 mm, which is smaller than that of a traditional machine cover, thereby reducing material costs.
[0016] As a further improved specific implementation method, the punching points 7 are provided with 12, and the number of the punching points 7 is reasonably arranged to ensure the structural strength.
[0017] As a further improved specific implementation, the punching point 7 is convexly arranged.
[0018] As a further improved specific implementation method, the upper flange 3, the double steps, the punching point 7 and the cover body 1 all adopt R-angle transition, which is easy to form and avoids stress concentration that may cause product rupture.
[0019] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
