Technical Field

[0001] This utility model relates to the field of automotive parts installation technology, specifically to a riveting installation structure for automotive door panel pulley pins. Background Technology

[0002] In the automotive manufacturing industry, the installation quality of the pulley pins on the car door panel directly affects the smoothness of the window regulator's sliding and its overall stability. Currently common installation methods have the following problems:

[0003] Insufficient fit between the pivot pin, pulley, and door panel causes the pulley to loosen easily during sliding, resulting in abnormal noise.

[0004] Traditional connection methods result in high friction, severe wear on pulleys and pins, and short service life.

[0005] The installation process relies on manual operation, which is inefficient and makes it difficult to guarantee installation accuracy.

[0006] Therefore, there is an urgent need for a shaft pin riveting installation structure that is compact, easy to install, and highly reliable. Utility Model Content

[0007] The purpose of this utility model is to provide a riveting installation structure for the axle pin of a car door panel pulley. By optimizing the axle pin connection method and pulley assembly design, the axle pin can be installed quickly and accurately, reducing friction loss, extending the service life of the component, and improving the performance of the car window regulator.

[0008] A riveting and mounting structure for a pulley pin on an automobile door panel includes: a pulley component, a pin mechanism, and a boss provided on the door panel body. The boss has a shaft hole, the pin mechanism is installed in the shaft hole, and the pulley component is installed on the pin mechanism.

[0009] The shaft pin mechanism includes an integrally formed first column and a second column. The first column is rotatably connected to a pulley component, and the second column is assembled in a shaft hole. A retaining ring is installed at the end of the first column, and a riveting head is installed at the end of the second column. The riveting head is riveted and fixed by a riveting machine to achieve a tight connection.

[0010] As a preferred embodiment of this utility model, the pulley component includes a pulley body, an inner ring protrusion and an outer ring protrusion fixedly installed on the pulley body; the inner ring protrusion is disposed on the adjacent surface of the pulley body and the boss, and is used to reduce the contact area with the surface of the boss, thereby reducing the friction; the outer ring protrusion is disposed on the opposite side of the inner ring protrusion and abuts against the outer periphery of the retaining ring.

[0011] As a preferred embodiment of this utility model, a pressure-bearing pad is also provided between the riveting head and the door panel body.

[0012] As a preferred embodiment of this utility model, the pressure pad includes an integrally formed pressure plate and an annular ring, a cylindrical slot is provided at the shaft hole, the annular ring is installed in the cylindrical slot, and the pressure plate is set close to the back of the boss.

[0013] As a preferred embodiment of this utility model, an anti-detachment block is fixedly provided on the boss to prevent the wire rope from derailing, and the anti-detachment block is located above the pulley component.

[0014] As a preferred embodiment of this utility model, a rolling bearing is installed between the pulley component and the axle pin mechanism.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] The riveting head is deformed and fixed by a riveting machine, eliminating the need for complex manual operations, significantly improving installation efficiency and reducing labor costs. The riveting head and the door panel body are rigidly connected by riveting, and with the help of precise positioning holes, the axle pin is prevented from loosening, improving structural stability. The rolling bearing significantly reduces the friction of the pulley rotation, reducing energy loss. The inner ring protrusion design further reduces the contact area, reduces wear, and extends the service life of the pulley and axle pin. The anti-detachment block structure effectively prevents the wire rope from going out of the groove, improving the safety of the window cranking machine. The pressure pad disperses the riveting impact force, protecting the door panel body from damage. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, a specific embodiment of the present invention for a riveting and mounting structure of a pulley pin for an automobile door panel includes: a door panel body 1, a boss 2 disposed on the door panel body 1, a pulley component 3, and a pin mechanism 4, the specific structure of which is as follows:

[0025] Boss 2: A shaft hole 101 is provided on the boss 2, and a cylindrical slot 102 is provided at the bottom of the shaft hole 101 for installing the pressure pad 6 and the shaft pin mechanism 4.

[0026] An anti-detachment block 5 is fixedly installed on the boss 2, located above the pulley component 3, to prevent the wire rope from detaching from the pulley groove.

[0027] The shaft pin mechanism 4 includes an integrally formed first column 402 and second column 403. The first column 402 is rotatably connected to the pulley component 3, and the second column 403 is inserted into the shaft hole 101.

[0028] A retaining ring 401 is installed at the end of the first column 402 to limit the axial movement of the pulley component 3;

[0029] The end of the second column 403 is provided with a riveting head 404, which is riveted to the door panel body 1 by a riveting machine.

[0030] Pulley component 3: includes a pulley body 301, an inner ring protrusion 302 and an outer ring protrusion 303 fixed on the pulley body 301;

[0031] The inner ring protrusion 302 is located on the side adjacent to the pulley body 301 and the boss 2, and is used to reduce the contact area with the boss 2 and reduce friction.

[0032] The outer ring protrusion 303 abuts against the outer periphery of the retaining ring 401, and cooperates with the retaining ring 401 to restrict the radial movement of the pulley component 3.

[0033] Pressure pad 6: includes an integrally formed pressure plate 601 and an annular ring 602. The annular ring 602 is embedded in the cylindrical slot 102 of the shaft hole 101. The pressure plate 601 is in close contact with the back of the boss 2 to disperse the impact force during riveting and protect the door panel body 1.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that a rolling bearing (not shown in the figure) is installed between the pulley component 3 and the first column 402 of the shaft pin mechanism 4 to further reduce rotational friction.

[0036] The working principle of this utility model is as follows: In this utility model, the pulley component 3 rotates freely around the first column 402 of the shaft pin mechanism 4 through the rolling bearing. The inner ring protrusion 302 reduces the friction with the boss 2. The outer ring protrusion 303 cooperates with the retaining ring 401 to limit the axial displacement. The anti-detachment block 5 prevents the wire rope from derailing. The pressure pad 6 disperses the impact force during riveting to ensure structural stability.
