Description

Technical Field

[0001] This invention relates to the field of steering wheel leather wrapping technology, and more specifically, to a structure for tightly bonding leather and adhesive to a steering wheel. Background Technology

[0002] Currently, the leather on steering wheels is applied manually with glue and then attached to the steering wheel frame. After defects such as bulges are found, a heat gun is used to heat the leather and then the bulges are manually scraped flat to complete the shaping.

[0003] However, manual scraping is inefficient and may damage the outer skin.

[0004] Therefore, this application proposes a structure in which the leather and adhesive of a steering wheel are tightly bonded together to solve the aforementioned problems. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a structure in which the leather and adhesive of a steering wheel are tightly bonded together.

[0006] The technical solution provided in this application for a steering wheel structure in which leather and adhesive are tightly bonded together is as follows:

[0007] A structure for a steering wheel where leather and adhesive are tightly bonded together includes:

[0008] A base, on which a vacuum flange is provided, and on which a lower support plate concentric with the vacuum flange is provided, and on which a lower silicone mold is provided, the lower silicone mold extending toward the vacuum flange and fixed at the connection between the vacuum flange and the upper end of the base;

[0009] The base is also movably provided with an upper cover plate, and an upper silicone mold is provided on the side of the upper cover plate facing the vacuum flange. Both the upper silicone mold and the lower silicone mold are provided with pressure rings on their surfaces.

[0010] The vacuum flange has a vacuum connection port at its bottom, and an air blowing port is provided on the lower half of the bottom side of the vacuum flange, which is located below the base.

[0011] Furthermore, a beam sensor is provided on the base around the lower support plate.

[0012] The above technical solution enables real-time monitoring of equipment operation status, ensuring the accuracy and quality of the bonding process.

[0013] Furthermore, proximity switches are symmetrically arranged on the base, and the proximity switches are located on the moving path of the upper cover plate.

[0014] The above technical solution can automatically sense the opening and closing of the top cover to control the linkage of other components, thus improving the convenience and safety of operation.

[0015] Furthermore, hydraulic rods are symmetrically arranged on the base, and the pistons of the hydraulic rods are movably connected to the upper cover plate.

[0016] The above technical solution makes the opening and closing of the top cover plate easier and smoother, reducing the labor intensity of the operator.

[0017] Furthermore, a sealing ring is also provided above the pressure ring on the lower silicone mold.

[0018] The above technical solutions improve the sealing performance of the vacuum system and ensure the effectiveness of vacuum adsorption.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] By using vacuum to deform a high-strength silicone film, the film is pressed onto the leather of the steering wheel at zero distance, allowing the wrinkles and bulges of the leather to be automatically shaped under vacuum pressure. This significantly improves the efficiency and quality of steering wheel leather bonding, reduces the complexity and labor intensity of manual operation, and avoids leather damage caused by improper operation, bringing significant technological progress to the steering wheel manufacturing industry.

[0028] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0029] This application discloses a structure for tightly bonding leather and adhesive to a steering wheel, comprising:

[0030] A base 1, a vacuum flange 2 is provided through the base 1, a lower support plate 3 concentric with the vacuum flange 2 is provided on the base 1, a lower silicone mold 4 is provided on the lower support plate 3, the lower silicone mold 4 extends towards the vacuum flange 2 and is fixed at the connection between the vacuum flange 2 and the upper end of the base 1.

[0031] The base 1 is also movably provided with an upper cover plate 5. An upper silicone mold 6 is provided on the side of the upper cover plate 5 facing the vacuum flange 2. Pressure rings 7 are provided on the surfaces of the upper silicone mold 6 and the lower silicone mold 4.

[0032] The bottom of the vacuum flange 2 is provided with a vacuum connection port 8, and the lower half of the bottom side of the vacuum flange 2 is also provided with an air blowing port 9, which is located below the base 1.

[0033] See Figure 1 , Figure 2 and Figure 3 A through-beam sensor 10 is installed on the base 1 around the lower support plate 3; this enables real-time monitoring of the equipment's operating status, ensuring the accuracy and quality of the bonding process.

[0034] See Figure 1 , Figure 2 and Figure 3 The base 1 is also symmetrically equipped with proximity switches 11, which are located on the moving path of the upper cover 5. The proximity switches 11 can automatically sense the opening and closing of the upper cover 5 to control the linkage of other components, thereby improving the convenience and safety of operation.

[0035] See Figure 1 , Figure 2 and Figure 3 Hydraulic rods 12 are symmetrically arranged on the base 1, and the piston of the hydraulic rod 12 is movably connected to the upper cover plate 5; making the opening and closing of the upper cover plate 5 easier and smoother, reducing the labor intensity of the operator.

[0036] See Figure 1 , Figure 2 and Figure 3 A sealing ring 13 is also provided above the pressure ring 7 on the lower silicone mold 4; this improves the sealing performance of the vacuum system and ensures the effect of vacuum adsorption.

[0037] The implementation principle of one embodiment of this application, which describes a steering wheel structure in which the leather and adhesive are tightly bonded, is as follows:

[0038] The bottom of the vacuum flange 2 is connected to the corresponding air blowing and vacuum devices. Both air blowing and vacuum devices are very mature technologies in this field, and will not be described in detail here.

[0039] Open the upper cover 5, place the leather-covered but unshaped steering wheel into the inverted frustum-shaped groove formed by the travel between the lower silicone mold 4 and the vacuum flange 2, and then close the upper cover 5. During the descent of the upper cover 5, the proximity switch 11 is triggered, allowing the control system to obtain the corresponding information. Then, the upper cover 5 is locked with a magnetic lock, and the vacuum generator is started to perform a vacuuming operation. The vacuuming time needs to last for 10 to 15 seconds, with a negative pressure of 0 to 80 kPa. The vacuum is used to deform the high-strength silicone film, allowing the silicone film to be pressed onto the leather of the steering wheel at zero distance, so that the wrinkles and bulges of the leather are automatically shaped under vacuum pressure.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
