Abstract
Description
Technical Field
[0001] The utility model relates to a rotation limiting thrust-stopping structure for the warping of an electric outboard motor. Background Art
[0002] An outboard motor, as the name implies, refers to a propulsion engine installed on the outside of the hull (side), usually suspended on the outside of the transom, also known as an outboard motor. During use, the outboard motor's manual tilting device needs to be used to manually adjust the outboard motor's tilting angle and adjust the propeller's water entry angle. However, in the prior art, the traditional outboard motor's tilting limit shaft is limited by a rotating shaft plus two thrust blocks, and the thrust block plane is limited by contact with the rotating bracket plane. The parts are complex and the installation process is cumbersome, which greatly affects the production efficiency. Therefore, it is necessary to improve it.
[0003] The traditional limit shaft does not limit its rotational freedom, and there may be a certain amount of shaking during the ship's movement; but if the rotational freedom of the limit shaft is completely restricted, the matching planes of the limit shaft and the rotating bracket may not be completely in line, resulting in line contact, which affects the assembly strength. At the same time, the traditional outboard motor lift limit shaft is limited by a rotating shaft plus two thrust blocks, and is limited by the contact between the thrust block plane and the rotating bracket plane. The parts are complex and the installation process is cumbersome, which greatly affects the production efficiency. Therefore, it is necessary to improve it.
[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a new type of electric outboard motor tilting rotation limit thrust structure to make it more valuable for industrial use. Utility Model Content

[0008] The limiting shaft comprises a limiting shaft body, which is in a square structure. The left end and the right end of the limiting shaft body are respectively connected to a left connecting column and a right connecting column which are connected to the bracket, and a retaining ring is mounted on the right connecting column.
[0009] Preferably, in the electric outboard motor tilting rotation limit thrust structure, the oil cylinder is fixed to the bracket via a fixed shaft connection.
[0010] Preferably, in the electric outboard motor tilting rotation limit thrust structure, the limit shaft body, the left connecting column and the right connecting column are an integrally formed structure.
[0011] Preferably, in the electric outboard motor tilting rotation limit thrust structure, the right connecting column is provided with a mounting groove for connecting a retaining ring.

[0024] Example
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a rotation limit thrust structure for lifting an electric outboard motor comprises a bracket 1, a lower side of the bracket 1 is connected to a side of a rotating bracket 2 through a rotating shaft, an upper side of the bracket 1 is penetrated with a limit shaft 3, the other side of the rotating bracket 2 is in contact with the limit shaft 3, an oil cylinder 4 is connected inside the bracket 1, a main driving shaft of the oil cylinder 4 is connected to one end of a main push rod 5, the other end of the main push rod 5 is connected to the rotating bracket 2, the oil cylinder 4 is provided with two secondary driving shafts, the secondary driving shaft is connected to one end of a balance rod 6, the other end of the balance rod 6 is connected to the rotating bracket 2, and a triangular structure is formed between the two balance rods 6 connected to the rotating bracket and the main push rod 5; the limit shaft 3 comprises a limit shaft body 31, the limit shaft body 31 is a square structure, the left end and the right end of the limit shaft body 31 are respectively connected to a left connecting column 32 and a right connecting column 33 penetrated on the bracket 1, and a retaining ring 34 is sleeved on the right connecting column 33.
[0026] The oil cylinder 4 in the utility model is connected and fixed on the bracket 1 through a fixed shaft, which can improve the stability of the oil cylinder.
[0027] The limiting shaft body 31, the left connecting column 32 and the right connecting column 33 in the present invention are an integrally formed structure.
[0028] In the present invention, a mounting groove 35 for connecting a retaining ring is provided on the right connecting column 33, and a blocking plate 36 is connected to the outer side of the left connecting column 32, so as to facilitate the installation of the retaining ring.
[0029] The left connecting column 32 in the utility model is connected to a limiting protrusion 37, and the limiting protrusion 37 is arranged to protrude from the inner side of the bracket 1. The rotating bracket 2 on the same side as the limiting protrusion is provided with a limiting groove (not shown) inserted into the limiting protrusion. An adjustable gap of 4° to 5° is provided between the limiting groove and the limiting protrusion 37, which can be adjusted during installation to facilitate the full contact between the rotating brackets, thereby improving the working stability of the rotating bracket.
[0030] The working principle of the utility model is as follows:
[0031] During specific operation, when adjusting the angle, the secondary drive shaft of the cylinder first pushes the two balance rods and the main drive shaft of the cylinder pushes the main push rod. The rotating bracket of the outboard motor rotates around the axis to an angle of 16 degrees with the vertical direction and maintains its angle unchanged. This angle is the working angle under normal use.
[0032] When the boat is operating in shallow water or being repaired, the outboard motor needs to be further raised. At this time, the main push rod of the main drive shaft of the cylinder and the balance rod of the auxiliary drive shaft further push and stabilize the outboard motor to the required position greater than 16 degrees, and the limit shaft is in contact with the rotating bracket.
[0033] When the outboard motor is sailing at full speed, it rotates to a vertical position. At this time, the thrust from the propeller is at its maximum. In addition to the main cylinder tilt rod and the auxiliary cylinder balance rod, its position is limited by the limit shaft and it bears the thrust from the propeller, thereby generating the maximum thrust.
[0034] 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.
[0035] In the description of this application, it should be noted that the terms "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or vertical, 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.
[0037] In the description of this application, it should also be noted 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
