Description

Technical Field

[0001] This utility model relates to the field of safety buckle technology, and in particular to an inertia washer for automotive seat belt buckles. Background Technology

[0002] Seatbelt buckles are important automotive safety devices. Their function is to work with seatbelts to secure occupants to their seats during a collision, thereby reducing the possibility of injury or death.

[0003] After long-term use, the locking force of the seat belt buckle is affected by the wear and aging of its parts. Therefore, the applicant has made a useful design and found a way to solve the above problem. The technical solution to be introduced below is produced in this context. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the traditional seat belt buckle mechanism and provide a product that increases locking force and extends service life.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0006] An inertia washer for a car seatbelt buckle includes a mounting base, a button inserted into the mounting base, and a latch inserted into the button. The button has a through groove for the latch to pass through. The bottom of both sides of the mounting base has a pressure-bearing portion. The outer wall of the mounting base has rotatable washers on both sides. Each washer has an elastic abutment portion that abuts against the pressure-bearing portion. An abutment portion is provided between the two washers. The abutment portion has an inclined first guide portion and is disposed in the through groove. The first guide portion extends to have an inclined second guide portion, and a gap is formed between the first guide portion and the through groove for the latch to enter.

[0007] Preferably, blind holes are provided on both sides of the outer wall of the fixing seat.

[0008] Preferably, the gasket has a first protrusion and is embedded in the blind hole.

[0009] Preferably, one of the gaskets has a bent extension, the extension having a second protrusion.

[0010] Preferably, a limiting part is provided on one side of the button and is located on the moving trajectory of the second protrusion, and the through groove is provided with a limiting groove and is located on the back of the contact part.

[0011] Preferably, an inclined surface is provided between the first guide portion and the contact portion.

[0012] Beneficial effects:

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, the locking tongue moves on the second guide and the first guide. As the locking tongue gradually penetrates deeper into the through groove, the contact part is pushed by the locking tongue, causing the action part to move towards the pressure-bearing part. The action part gradually stores energy and releases elastic force to the locking tongue, so that the locking tongue is pressed tightly against the through groove by the contact part, thereby increasing the friction and further increasing the locking force on top of the original locking force of the product. This overcomes the technical problems mentioned in the background art and gives the product the advantages of increased locking force and improved service life. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0023] Reference example Figures 1 to 3 An inertia washer for a car seatbelt buckle includes a mounting base 1, a button 2 inserted into the mounting base 1, and a latch 3 inserted into the button 2. The button 2 has a through groove 21 through which the latch 3 passes. Pressure-bearing portions 11 are provided at the bottom of both sides of the mounting base 1. Rotatable washers 4 are provided on both sides of the outer wall of the mounting base 1. Each washer 4 has an elastic actuating portion 41 that abuts against the pressure-bearing portions 11. An abutting portion 42 is provided between the two washers 4. The abutting portion 42 has an inclined first guide portion 43 disposed in the through groove 21. The first guide portion 43 extends to provide an inclined second guide portion. The second guide part 44 forms a gap between itself and the through groove 21 for the locking tongue 3 to enter. When the locking tongue 3 abuts against the second guide part 44, as the locking tongue 3 gradually penetrates into the through groove 21, the pad 4 is gradually rotated by the pushing force of the locking tongue 3. When the locking tongue 3 enters the first guide part 43, the pad 4 receives more force and accelerates its rotation, causing the action part 41 to move towards the pressure bearing part 11. The action part 41 gradually stores energy and releases elastic force to the locking tongue 3, so that the locking tongue 3 is pressed tightly against the through groove 21 by the contact part 42, thereby increasing the friction and further increasing the locking force on top of the original locking force of the product.

[0024] It is worth mentioning that blind holes 12 are provided on both sides of the outer wall of the fixed base 1, and the blind holes 12 allow the gasket 4 to rotate around the axis.

[0025] It is worth mentioning that the gasket 4 is provided with a first protrusion 45 and is embedded in the blind hole 12. The first protrusion 45 is used in conjunction with the blind hole 12.

[0026] It is worth mentioning that one of the gaskets 4 is provided with a bent extension 46, and the extension 46 is provided with a second protrusion 47;

[0027] It is worth mentioning that a limiting part 22 is provided on one side of the button 2 and is set on the movement trajectory of the second protrusion 47. The through groove 21 is provided with a limiting groove 23 and is set on the back of the contact part 42. When the second protrusion 47 abuts against the limiting part 22, the pad 4 can no longer rotate, thereby ensuring that the action part 41 is not excessively squeezed, resulting in a reduction of elastic potential energy. When the locking tongue 3 is not inserted, the limiting groove 23 prevents the pad 4 from reversing.

[0028] It is worth mentioning that an inclined surface 48 is provided between the first guide part 43 and the contact part 42. The inclined surface 48 allows the locking tongue 3 to enter above the contact part 42, reducing the friction of the locking tongue 3 against the contact part 42.

[0029] The above design scheme enables the product to achieve advantages such as good safety, good stability, and good heat dissipation.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
