Description

Technical Field

[0001] The present invention relates to a human body mold, and particularly to a human body mold and a rubber coating method for rubber coating on the surface of a seat belt. Background Art

[0002] Rubber coating on the surface of a seat belt can provide a protective layer for the seat belt, prevent external pollutants such as oil stains from contacting the seat belt fibers and affecting the protective performance of the seat belt, and improve the service life of the seat belt. When rubber coating the existing seat belts, the seat belts are usually laid flat for rubber coating. For the seat belts after rubber coating in this state, when worn by a human body, the comfort is poor (when worn by a human body, some parts of the seat belt are stretched open, and some parts are not stretched open. Since the seat belt is laid flat for rubber coating, that is, the rubber coating thickness is the same when not stretched open, resulting in the rubber coating thickness at the stretched open parts being thinner than that at the non - stretched open parts), and it will also affect the performance of the seat belt and the service life. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a human body mold and a rubber coating method that are convenient for rubber coating by supporting the seat belt to simulate the state of the seat belt worn on the human body and realizing three - dimensional pre - shaping of the seat belt.

[0004] The purpose of the present invention is achieved by the following technical solutions:

[0005] A human body mold for rubber coating on the surface of a seat belt includes a human - shaped mold airbag and a support base. An inflation device is provided on the support base, the output end of the inflation device is connected to the human - shaped mold airbag, and the support base is also provided with a hanging rope for hanging the seat belt and a support ring for stretching the seat belt.

[0006] Preferably, there are two hanging ropes, which are symmetric about the center of the support base, and the hanging ropes correspond to the shoulders of the seat belt.

[0007] Preferably, a connecting rod is provided on the support base, the end of the connecting rod fixes the support ring, the center line of the connecting rod is perpendicular to the plane of the support base and the plane where the support ring is located at the same time, and the connecting rod does not contact the inflated human - shaped mold airbag.

[0008] Preferably, it further includes a fixing base, and the support base is rotatably arranged below the fixing base.

[0009] Preferably, a first gear is provided at the center of the support base, a motor is provided in the fixing base, and a second gear that cooperates with the first gear is provided at the output end of the motor.

[0010] Preferably, when the human - shaped mold airbag is inflated, the support ring is embedded in the outer surface of the human - shaped mold airbag.

[0011] A rubber coating method for rubber coating on the surface of a seat belt using the above - mentioned human body mold includes the following steps:

[0012] Step 1: Turn on the inflating device, inflate the airbag of the humanoid mold, and put the support ring on the airbag of the humanoid mold.

[0013] Step 2: Wear the seat belt on the airbag of the humanoid mold, and pass the shoulder strap of the seat belt through the hanging rope.

[0014] Step 3: Continue to inflate the airbag of the humanoid mold so that the airbag of the humanoid mold fits the inner surface of the seat belt, and the support ring is embedded in the outer surface of the airbag of the humanoid mold.

[0015] Step 4: Use a spray gun or brush to evenly spray the sizing agent on the outer surface of the seat belt.

[0016] Step 5: After the sizing agent on the outer surface of the seat belt dries and hardens, empty the gas in the airbag of the humanoid mold to create an operating space for coating the inner surface.

[0017] Step 6: Use a spray gun or brush to evenly spray the sizing agent on the inner surface of the seat belt. After the sizing agent on the inner surface of the seat belt dries, the coating is completed.

[0018] Preferably, it further includes Step 7: Trim the excess sizing agent at the edge of the seat belt, and then remove the seat belt.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) A human mold for supporting the seat belt is provided. By simulating the state of the seat belt worn on the human body, three-dimensional pre-shaping of the seat belt is achieved. Coating in this state can improve the comfort of the human body wearing after coating and further improve the service life.

[0021] (2) The support base is rotatable, allowing the airbag of the humanoid mold to rotate slowly, which is convenient for operators to perform all-round coating operations on the seat belt, saving manpower and improving work efficiency. Description of the Drawings

[0026] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] Referring to Figures 1-3 , the present invention provides a technical solution:

[0028] A human body mold for rubber coating on the surface of a seat belt includes a humanoid mold airbag 1 and a support base 2. An inflation device is provided on the support base 2, and the output end of the inflation device is connected to the humanoid mold airbag 1. A hanging rope 4 for hanging the seat belt and a support ring 8 for stretching the seat belt are also provided on the support base 2.

[0029] Further, there are two hanging ropes 4, which are centrosymmetric about the center of the support base 2. The hanging ropes 4 correspond to the shoulders of the seat belt. The hanging ropes 4 can be made of thinner steel wires to reduce the contact area with the shoulders of the seat belt, that is, to increase the rubber coating area of the subsequent seat belt.

[0030] Further, a connecting rod 9 is provided on the support base 2. The end of the connecting rod 9 fixes the support ring 8. The center line of the connecting rod 9 is perpendicular to the plane of the support base 2 and the plane where the support ring 8 is located at the same time. The support ring 8 is used to support the seat belt to keep it in the state when worn by the human body. The connecting line between the center of the support ring 8 and the center of the humanoid mold airbag 1 is substantially perpendicular to the horizontal plane. The connecting rod 9 does not contact the inflated humanoid mold airbag 1, that is, it ensures that the connecting rod 9 and the inflated humanoid mold airbag 1 do not interfere with each other.

[0031] Further, it further includes a fixing base 3. The support base 2 is rotatably arranged below the fixing base 3 (which can be connected by a rotating bearing). Among them, a first gear 5 is provided at the center of the support base 2, and a motor 7 is provided in the fixing base 3. A second gear 6 that cooperates with the first gear 5 is provided at the output end of the motor 7.

[0032] Further, when the humanoid mold airbag 1 is inflated, the support ring 8 is embedded in the outer surface of the humanoid mold airbag 1 (in order to make the humanoid mold airbag 1 fit more closely to the inner surface of the seat belt when inflated).

[0033] A rubber coating method for rubber coating on the surface of a seat belt using the human body mold includes the following steps:

[0034] Step 1: Turn on the inflation device, inflate the humanoid mold airbag 1, and put the support ring 8 on the humanoid mold airbag 1;

[0035] Step 2: Wear the seat belt on the humanoid mold airbag 1, and make the shoulder straps of the seat belt pass through the hanging ropes 4;

[0036] Step 3: Continue to inflate the inflatable airbag 1 of the humanoid mold so that the inflatable airbag 1 of the humanoid mold fits the inner surface of the safety belt. After fitting, the support ring 8 should be embedded in the outer surface of the inflatable airbag 1 of the humanoid mold (as Figure 3 shown);

[0037] Step 4: Use a spray gun or brush to evenly spray the sizing agent on the outer surface of the safety belt;

[0038] Step 5: After the sizing agent on the outer surface of the safety belt dries and hardens, evacuate the gas in the inflatable airbag 1 of the humanoid mold. After evacuation, the inflatable airbag 1 of the humanoid mold shrinks and becomes smaller, creating a spraying operation space inside the safety belt. At this time, the inflatable airbag 1 of the humanoid mold no longer provides support to the safety belt. The support is provided by the hanging rope 4 on the shoulder. The support ring 8 keeps the safety belt roughly in the state on the inflatable airbag 1 of the humanoid mold. Since the sizing agent on the outer surface of the safety belt dries and hardens, the safety belt remains in the worn state on the inflatable airbag 1 of the humanoid mold without applying a large external force, which is convenient for subsequent coating of the inner surface of the safety belt;

[0039] Step 6: Use a spray gun or brush to evenly spray the sizing agent on the inner surface of the safety belt. After the sizing agent on the inner surface of the safety belt dries, the coating is completed.

[0040] Among them, during the spraying process in Step 4 and Step 6, the motor 7 can be turned on, and the second gear 6 rotates to drive the first gear 5 to rotate, that is, the support seat 2 rotates, making the inflatable airbag 1 of the humanoid mold rotate slowly, which is convenient for the operator to perform a full-range coating operation on the safety belt, saving manpower and improving work efficiency.

[0041] Further, it further includes Step 7: Trim the excess sizing agent at the edge of the safety belt, and then remove the safety belt.

[0042] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments. Instead, it can be used in various other combinations, modifications, and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
