Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a wheel hub insert. Background Technology

[0002] The existing inserts include a panel, a locking foot on the back of the panel, and a retaining spring for supporting the locking foot. The existing retaining spring has a closed structure, and it is difficult to have space to open a clearance hole for the air supply nozzle. Therefore, the existing inserts cannot be installed at the air supply nozzle. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a wheel hub insert that can both avoid the valve to meet the tire inflation needs and decorate the wheel hub to reduce the wind resistance of the wheel hub.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wheel hub insert, including a panel, several retaining feet disposed on the back of the panel, and retaining springs for supporting the retaining feet. The panel has a clearance hole for the exposed air nozzle. A protective plate is disposed on the back of the panel along the edge of the clearance hole. The retaining spring is C-shaped and has two free ends. One end of the retaining spring abuts against one side of the protective plate, and the other end of the retaining spring passes through the retaining foot and abuts against the other side of the protective plate. The principle of this utility model: the clearance hole on the insert exposes the air nozzle, allowing the insert to be installed at the air nozzle position of the wheel hub, avoiding the air nozzle to meet the tire inflation needs, while also decorating the wheel hub and reducing wind resistance; the protective plate is disposed around the clearance hole, and the retaining spring is C-shaped, with its two ends opening to abut against the two sides of the injection-molded insert protective plate. The protective plate provides support for the retaining spring, thereby enabling the retaining spring to support the other retaining feet, achieving a relatively ideal holding force.

[0005] As an improvement, the locking feet are distributed around the perimeter of the protective plate.

[0006] As an improvement, the locking foot includes a locking seat, a vertical plate on the locking seat, a locking platform on the outside of the vertical plate, and a limiting groove on the inside. The locking seats of adjacent locking feet are connected to each other by a connecting plate, and the locking spring passes through the limiting groove.

[0007] The beneficial effects of this utility model compared with the prior art are:

[0008] The air inlet is exposed through the clearance hole on the insert, allowing the insert to be installed at the hub valve position. This avoids the valve to meet the tire inflation needs while also decorating the hub and reducing wind resistance. A protective plate is set around the clearance hole, and the retaining spring is C-shaped with its two ends opening to press against the two sides of the injection-molded insert protective plate. The protective plate provides support for the retaining spring, thereby enabling the retaining spring to support the other retaining feet and achieve a relatively ideal holding force. Attached Figure Description

[0009] Figure 1This is a schematic diagram showing the fit between the insert and the wheel hub.

[0010] Figure 2 This is a schematic diagram of the back of the inlay. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figure 1 , 2 As shown, a wheel hub insert 2 is installed at the ventilation hole of a wheel hub 1. The insert 2 includes a panel 21, several retaining feet 22 on the back of the panel 21, and retaining springs 23 for supporting the retaining feet 22. The shape of the panel 21 is similar to that of the ventilation hole on the wheel hub, and an air nozzle 3 is provided at the ventilation hole. The panel 21 has a clearance hole 25 for the air nozzle 3 to protrude. A protective plate 24 is provided on the back of the panel 21 along the edge of the clearance hole 25. The retaining spring 23 is C-shaped and has two free ends. One end of the retaining spring 23 abuts against one side of the protective plate 24, and the other end of the retaining spring 23 passes through the retaining feet 22 and abuts against the other side of the protective plate 24. The retaining feet 22 are distributed around the perimeter of the protective plate 24, and in principle, the shape of the panel 21 is used to distribute the retaining feet 22 so that the force on each retaining foot 22 is even. The retaining foot 22 includes a retaining seat, a vertical plate on the retaining seat, a retaining platform on the outside of the vertical plate, and a limiting groove on the inside. The retaining seats of adjacent retaining feet 22 are connected to each other by a connecting plate, and the retaining spring 23 passes through the limiting groove. The principle of this utility model is as follows: the air inlet 3 is exposed through the clearance hole on the insert, allowing the insert 2 to be installed at the position of the wheel hub air inlet 3. This avoids the air inlet 3 while meeting the tire inflation needs, and also decorates the wheel hub 1 and reduces wind resistance. A protective plate 24 is set around the clearance hole. The retaining spring 23 is C-shaped, with its two ends opening and pressing against the two sides of the injection-molded insert protective plate 24. The protective plate 24 provides support for the retaining spring 23, thereby enabling the retaining spring 23 to support the other retaining feet 22 and achieve a relatively ideal holding force.
