Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy scooters, and in particular to an integrated upper arm for aluminum alloy scooters. Background Technology

[0002] The original scooter fork frame was made by welding steel parts. In recent years, aluminum alloy forging technology has become increasingly mature and the cost has gradually decreased. Therefore, the original carbon steel parts have been replaced to improve the vehicle's lightweight performance. Since the yield rate of aluminum alloy forging is greatly affected by the casting pressure, in order to ensure the strength of the formed product, it is necessary to avoid large wall thickness product structures as much as possible. The original structure cannot be directly applied to aluminum parts. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide an integrated upper arm for an aluminum alloy scooter, so as to improve the forming rate.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An integrated upper arm for an aluminum alloy scooter includes a steering column joint for connecting to a steering column and a fixing seat for fixing to the scooter body. The fixing seat and the steering column joint are connected by a pair of first connecting arms and second connecting arms.

[0006] Furthermore, the first connecting arm and the second connecting arm are separated by a partition hole.

[0007] Furthermore, the cross-section of the opening has a structure that is thicker at the rear end and narrower at the front end, so that the first connecting arm and the second connecting arm form a triangular connection structure.

[0008] Furthermore, the rear thickness of the first connecting arm and the second connecting arm is greater than the front thickness.

[0009] Furthermore, a connection hole is provided on the fixing seat for fixing and connecting with the vehicle body.

[0010] Furthermore, a connecting reinforcing beam is provided between the first connecting arm and the second connecting arm, and the reinforcing beam is located at the front of the first connecting arm and the second connecting arm.

[0011] The beneficial effects of this utility model are as follows:

[0012] The present invention provides an integrated upper arm for an aluminum alloy scooter. By adjusting the thickness distribution structure of the connecting arm and increasing the reinforcing ribs to improve the strength of the connecting arm, the wall thickness of the connecting arm can be reduced to meet the process requirements of aluminum alloy forging while ensuring strength.

[0016] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does 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, it should not be construed as a limitation of this utility model.

[0017] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the relevant listed items.

[0018] In the specification, when an element is described as being "on," "fixed" to, "connected" to, or "joined" to another element, the element may be directly located on, fixed to, connected to, joined to, or in contact with the other element, or there may be an intermediate element present. In the specification, the description of a feature being arranged "adjacent" to another feature may refer to a feature having a portion that overlaps with the adjacent feature or a portion located above or below the adjacent feature.

[0019] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.

[0020] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0021] Figure 1 This design showcases an integrated upper arm for scooters, primarily composed of a pair of first connecting arms 20 and second connecting arms 30. The first and second connecting arms 20 and 30 connect the steering column sections 10 and the mounting base 50 located at their respective ends, forming a single unit, thus altering the original welded structure. An opening 40 is arranged between the first and second connecting arms 20 and 30. Considering that the integrated upper arm must be formed using aluminum alloy forging, to ensure the forming density of key components, especially the first and second connecting arms 20 and 30, during this manufacturing process, the lateral cross-sectional area of ​​the opening 40 relative to the first and second connecting arms 20 and 30 must be maximized. This ensures that the first and second connecting arms 20 and 30 are subjected to pressure during forming, guaranteeing density. Furthermore, the opening 40 is designed to be wider at the rear end 41 and narrower at the front end 42. The thickness of the rear portion 22 of both the first and second connecting arms 20 and 30 is slightly greater than the thickness of their front portion 21.

[0022] Reference Figure 2 The injection port 1 is located on both sides of the fixed base 50 and at the front end of the steering column 10. Therefore, the pressure is greatest at the middle 23 of the first connecting arm 20 and the second connecting arm 30 when the molten aluminum flows towards the center. Since the first connecting arm 20 and the second connecting arm 30 are designed to be relatively thin, a reinforcing beam 60 is added between them. The reinforcing beam 60 is specifically located at the front 21 of the first connecting arm 20 and the second connecting arm 30. A connection hole 51 for connecting to the vehicle body is also provided on the fixed base 50.
