Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, specifically to an injection-molded connection structure for the main body frame of an automotive dashboard. Background Technology

[0002] To ensure the functionality and durability of the instrument panel body, its frame surface needs to be covered with a skin. Specifically, after cleaning the frame surface, pressure is applied to the heated skin, and with the help of suction from equipment such as a vacuum pump, the skin is tightly adhered to the frame surface under negative pressure, thus completing the covering operation. However, after the skin is covered, the edges of the skin will remain on the upper frame, especially on the reinforcing frames on both sides of the existing instrument panel body frame. Due to the relatively curved structure of the whole, the edges of the cut skin will have wrinkles, which will affect the fitting accuracy between the instrument panel body frame and the side brackets of the upper body. Utility Model Content

[0003] The purpose of this utility model is to provide an injection-molded connection structure for the main body frame of an automotive dashboard, in order to solve the problem that, in the prior art, the edges of the outer skin after cutting the reinforcing frame on both sides of the main body frame have wrinkles due to the relatively curved overall structure, which affects the assembly accuracy between the main body frame and the side bracket of the upper body.

[0004] A car dashboard upper body frame injection molding connection structure includes a reinforcing frame disposed on both sides of the upper body frame of the car dashboard. The reinforcing frame is integrally fitted with the side bracket of the upper body. The side end of the reinforcing frame is provided with a groove. The groove is used to finish the edge of the outer skin covering the upper body frame of the dashboard. A connector is provided on one side of the groove on the reinforcing frame. The connector closes the opening area of ​​the groove.

[0005] Preferably, the connector has an inner groove in the middle, which corresponds to the slot.

[0006] Preferably, the connector is integrally injection molded into a plate frame shape and is formed integrally with the reinforcing skeleton.

[0007] Preferably, the lower edge of the connector's frame is positioned above the lower edge of the reinforcing skeleton.

[0008] Preferably, the thickness of the connecting plate frame is less than the thickness of the side end of the reinforcing skeleton.

[0009] Preferably, the inner sidewall of the reinforcing frame is provided with a skin edge trimming groove, which is located on both sides of the groove opening area.

[0010] The advantages of this utility model are as follows: by opening a slot at the side end of the reinforcing frame, the slot can be prevented from deforming due to thermal stress changes during the processing, thanks to the strength of the connecting parts. After the surface of the main frame of the instrument panel is covered, the edge of the covering skin of the reinforcing frame area can be inserted into the slot and the edge is glued to the edge finishing groove to eliminate edge wrinkles of the covering skin and ensure the fitting accuracy between the main frame of the instrument panel and the side bracket of the upper body after the skin is covered.

[0015] Among them, 1-reinforcing skeleton; 2-groove; 3-connector; 4-inner groove; 5-surface edge trimming groove. Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, an injection-molded connection structure for the main body frame of an automotive dashboard includes a reinforcing frame 1 located on both sides of the main body frame of the automotive dashboard. The reinforcing frame 1 is integrally fitted with the side bracket of the upper body. A slot 2 is provided at the side end of the reinforcing frame 1. The slot 2 is used to finish the edge of the outer skin covering the main body frame of the dashboard. A connector 3 is provided on one side of the slot 2 on the reinforcing frame 1. The connector 3 closes the opening area of ​​the slot 2.

[0018] In this embodiment, the connector 3 has an inner groove 4 in the middle, which corresponds to the slot 2.

[0019] In this embodiment, the connector 3 is integrally injection molded into a plate frame shape and the reinforcing skeleton 1.

[0020] In this embodiment, the lower edge of the plate frame of the connector 3 is positioned above the lower edge of the reinforcing skeleton 1.

[0021] In this embodiment, the thickness of the plate frame of the connector 3 is less than the thickness of the side end of the reinforcing skeleton 1.

[0022] In this embodiment, a skin edge trimming groove 5 is provided on the inner sidewall of the reinforcing frame 1, and the skin edge trimming groove 5 is located on both sides of the groove opening 2 area.

[0023] Working process and principle: In this embodiment, during the processing, since a connector 3 is provided on one side of the slot 2 on the reinforcing frame 1, the connector 3 closes the opening area of ​​the slot 2. Before the main body frame of the instrument panel is covered with skin, the connector 3 needs to be cut off. The setting of the inner groove 4 ensures that it can be completely cut off without affecting the internal structure of the slot 2. After the surface of the main body frame of the instrument panel is covered, the edge of the covered skin in the reinforcing frame 1 area can be inserted into the slot 2 and the edge is sealed and bonded to the skin edge sealing groove 5.

[0024] Based on the above, this utility model provides a slot 2 at the side end of the reinforcing frame 1. During the processing, with the strength of the connector 3, the slot 2 can be prevented from deforming due to changes in thermal stress. After the surface of the main frame on the instrument panel is covered, the edge of the covering skin in the reinforcing frame 1 area can be inserted into the slot 2 and then glued to the skin edge finishing groove 5 to eliminate edge wrinkles of the covering skin and ensure the fitting accuracy between the main frame on the instrument panel and the side bracket of the upper body after the skin is covered.

[0025] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
