Description

Technical Field

[0001] This utility model relates to a wedge block, and more particularly to a wedge block for use in an electric angle adjuster. Background Technology

[0002] In car seat adjusters, wedge blocks, in conjunction with a four-bar linkage, can adjust the seat angle, achieving changes in seat cushion height through minute displacement to meet the comfort needs of passengers of different body types. However, in existing electric seat adjusters, the wedge block structure in disc adjusters suffers from significant variations in structural thickness, resulting in uneven overall structural strength and making it prone to deformation under driving force. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a wedge block for an electric angle adjuster, which has high overall structural strength and is not easily deformed.

[0004] To achieve this objective, the structure adopted by this utility model is as follows: a wedge block for an electric angle adjuster, including a body, the body being an arc-shaped alloy block, a first groove being provided on one end face of the body, and one or more second grooves being provided on the inner ring surface of the body.

[0005] The top and bottom surfaces of the body are provided with bosses, and the bosses are chamfered with the body.

[0006] The inner annular surface of the body is composed of a first arc surface, a second arc surface, and a plane connected in sequence.

[0007] The radius of the first arc surface is larger than that of the second arc surface.

[0008] A second groove is provided between the second arc surface and the plane.

[0009] The first arc surface is near the end of the first groove.

[0010] The main body is integrally formed using powder metallurgy.

[0011] The included angle between the two ends of the main body is 90° to 110°.

[0012] The included angle between the two ends of the body is 100°.

[0013] Its beneficial effects are: the structure of this utility model is reasonably and ingeniously designed, the one-piece molded structure has high structural strength, the overall thickness difference is small, and it is not easy to deform. Attached Figure Description

[0014] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0015] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0016] Figure 2 This is a front view of the structure of this utility model;

[0017] Figure 3 This is a side view of the structure of this utility model. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for 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. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1-3 The diagram illustrates a wedge-shaped block for an electric angle adjuster, comprising a body 1, which is an arc-shaped alloy block. A first groove 3 is provided on one end face of the body 1, and one or more second grooves 2 are provided on the inner ring surface of the body 1. The body 1 is integrally formed using powder metallurgy, and the metallurgical powder comprises a proportional mixture of iron, nickel, copper, and carbon. Due to its maintainability and integral powder metallurgy forming process, the body exhibits high structural strength, strong pressure resistance, and is not prone to deformation under high pressure. Therefore, when used as a structural block for amplifying mechanical effects in an electric angle adjuster, it has a longer service life.

[0022] The top and bottom surfaces of the main body 1 are provided with protrusions 7. The protrusions 7 and the main body 1 are chamfered. The area of ​​the protrusions 7 is smaller than that of the main body. Therefore, after installation, there is a certain space between the protrusions 7 and the main body 1, so that the main body 1 can have a certain amount of expansion and contraction due to thermal expansion and contraction.

[0023] The inner ring surface of the body 1 is composed of a first arc surface 4, a second arc surface 5 and a plane 6 connected in sequence. The radius of the first arc surface 4 is larger than that of the second arc surface 5. The first arc surface 4 is close to one end of the first groove 3. The irregular structure of the inner ring surface can increase the contact area with other components of the electric angle adjuster and improve the connection strength.

[0024] A second groove 2 is provided between the second arc surface 5 and the plane 6. The second groove 2 is used for the insertion of connecting parts or limiting parts.

[0025] The included angle between the two ends of the body 1 is 90° to 110°, preferably 100°.

[0026] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
