Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycles, in particular to a durable connecting piece for a side beam of a light electric tricycle. Background Art

[0002] Electric tricycles are convenient and self-use transportation tools that we often use in our daily lives. They can be used to carry small amounts of goods in daily life and are very convenient to use. When assembling an electric tricycle, we need to use a variety of connectors to facilitate overall assembly; at the same time, in order to ensure the structural stability between the rear drive shaft and the overall bridge frame, a pull rod is usually used to connect the rear bridge frame to the side beam. Since the connection of the side beam is a curved side beam that is bent through a rectangular tube, and the connection between the pull rod and the side beam is located at the bent edge, a connector is welded at the bent edge to achieve the connection between the pull rod and the side beam. However, since the wall of the side beam tube is thinner after stretching, and the traditional connector is directly welded at the weak point, during the use of the vehicle, the pull rod will constantly pull the connector, and the weak point can bear less force, so it is easy to tear the side beam after being subjected to force. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a durable connector for the side beams of a light electric tricycle. The utility model has a simple structure and changes the connection method of the original connector, which not only improves the tensile strength of the connection and makes the side beams less likely to be torn, but also makes the overall connection more stable, thereby increasing the service life of the side beam connection.

[0004] The purpose of the utility model is achieved through the following technical scheme: a durable connector for the side beam of a light electric tricycle, comprising two connecting plates and a transverse plate for connecting the two connecting plates, the connecting plates comprising a welding portion, a connecting portion and a lifting ear portion, the two ends of the transverse plate are respectively fixedly connected to the welding portions of the two connecting plates, the connecting portion is used to connect the welding portion and the lifting ear portion, and the connecting portion has the same angle with the welding portion and the lifting ear portion, the lifting ear portion is parallel to the welding portion, and the angle range is 30° to 60°.

[0005] In one preferred embodiment, the welding portion is in a trapezoidal shape, and mounting grooves are provided on the long sides of two parallel sides of the welding portion, and both ends of the horizontal plate are arranged in the mounting grooves.

[0006] In one preferred embodiment, chamfers are provided at the corners of the welding portion and at the joints between the connecting portion, the welding portion and the lifting ear portion.

[0007] The beneficial effects of the utility model are as follows: the utility model has a simple structure, changes the connection mode of the original connection piece, not only improves the tensile strength of the connection, makes the side beam not easy to be torn, but also makes the overall connection more stable, and improves the service life of the side beam connection. The inner side surface of the welding part is fitted with the two side walls of the side beam, and then welded, because the two side walls are not stretched when bent, the wall thickness remains unchanged, so the resistance is strong, and the welding surface can be effectively increased, making the connection tighter and ensuring better tensile strength.

[0013] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0016] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0017] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0018] The terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0019] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal, vertical or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In addition, the terms "roughly" and "basically" are intended to explain that the relevant content does not require absolute precision, but can have certain deviations. For example, "roughly equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" in actual production and operation, there are generally certain deviations. Therefore, in addition to absolute equality, "roughly equal" also includes the above-mentioned situation with certain deviations. Taking this as an example, in other cases, unless otherwise specified, the terms "roughly" and "basically" have similar meanings to the above.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The utility model has a simple structure and changes the connection mode of the original connector, which not only improves the tensile strength of the connection, making the side beam 3 not easily torn, but also makes the overall connection more stable, thereby improving the service life of the connection of the side beam 3. The inner side surface of the welding portion 11 is fitted with the two side walls of the side beam 3 and then welded. Because the two side walls are not stretched when bent, the wall thickness remains unchanged, so the resistance is strong, and the welding surface can be effectively increased, making the connection tighter and ensuring better tensile strength.

[0023] The welding part 11 is in a trapezoidal shape, and mounting grooves are provided on the long sides of the two parallel sides of the welding part 11, and the two ends of the horizontal plate 2 are arranged in the mounting grooves.
