Description

Technical Field

[0001] This utility model relates to the field of foot pedal technology for top flow machines, specifically to a structure for a foot pedal of a top flow machine with freely adjustable damping force. Background Technology

[0002] A propeller motor is a small marine propulsion device that is powered by a battery and whose motor shaft extends directly to drive the propeller. It is usually used as a secondary power source for fishing and other recreational activities to control the course of the boat or to achieve automatic positioning. The main control methods are foot pedal and remote control.

[0003] Among them, foot pedals require precise control of the pedaling force; if the force is too light, the direction adjustment will be inadequate and the response will be delayed, affecting the accuracy of the operation; if the force is too heavy, the resistance of the transmission components will increase, making it difficult to pedal and increasing operator fatigue; the current selection of damping force for top flow machine feet is relatively limited, and since different people have different pedaling force, it is difficult for users to select the damping force that suits them. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that the selection of the damping force of the existing top flow machine foot is relatively simple. Since different people have different pedaling force, it is difficult for users to select the damping force that suits them.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a structure for a foot pedal of a top-flow machine with freely adjustable damping force, comprising: Base; A pedal, the middle part of which is hinged to the base; A damper, wherein a plurality of the dampers are arranged along the axis of the pedal hinge, and each of the dampers is provided with a connection hole for connection; A transmission column, rotatably mounted on a base, has its head end inserted into a connecting hole, and its length is adjustable to adjust the number of connecting holes the head end of the transmission column can be inserted into on the damper; and A transmission assembly connects the transmission column and the pedal to enable the transmission column and the pedal to rotate synchronously.

[0006] Preferably, the transmission assembly includes: a half gear and a transmission gear; the half gear is fixedly mounted on the pedal, and the axis of the half gear is coaxially arranged with the axis of the pedal hinge; the transmission gear is rotatably mounted on the base, and the transmission gear is coaxially fixed with the transmission column; and the transmission gear meshes with the half gear.

[0007] Preferably, the diameter of the half gear is larger than the diameter of the transmission gear.

[0008] Preferably, the plurality of said dampers are mounted on the base by screws.

[0009] Preferably, a sleeve is provided between two adjacent dampers, and the sleeve is fitted onto the screw.

[0010] Compared with the prior art, the present invention has at least the following advantages: In this invention, when adjusting the foot pedal damping force, the length of the transmission column is first adjusted. To increase the damping force, the transmission column is lengthened so that more damper connection holes can be inserted into its actual end. To decrease the damping force, the transmission column is shortened to reduce the number of dampers inserted into the connection holes. Then, the pedal is stepped on, and the pedal rotates around the hinge point, driving the transmission column to rotate synchronously through the transmission assembly. At this time, the dampers inserted into the transmission column work together to produce a damping effect. The more dampers inserted, the greater the overall damping force, and vice versa. This structure changes the number of dampers involved in the operation by adjusting the number of damper connection holes inserted into the transmission column, thereby achieving free adjustment of the damping force and adapting to the personalized needs of different users for the foot pedal resistance of the top flow machine.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] See Figures 1-3The present invention provides an embodiment of a structure for a foot pedal of a top-flow machine with freely adjustable damping force, comprising: a base 1, a pedal 2, a damper 3, a transmission column 4, and a transmission assembly; the middle part of the pedal 2 is hinged to the base 1; multiple dampers 3 are arranged along the axis of the hinge of the pedal 2, and each damper 3 is provided with a connecting hole 5 for connection; the transmission column 4 is rotatably mounted on the base 1, the head end of the transmission column 4 is inserted into the connecting hole 5, and the length of the transmission column 4 is adjustable to adjust the number of times the head end of the transmission column 4 is inserted into the connecting hole 5 on the damper 3; the transmission assembly connects the transmission column 4 and the pedal 2 so that the transmission column 4 and the pedal 2 rotate synchronously.

[0018] In practice, the pedal 2 is hinged to the base 1 at the middle. Multiple dampers 3 are arranged along the hinge axis of the pedal 2. Each damper 3 has a connection hole 5. The transmission column 4 is rotatably mounted on the base 1. Its head end is inserted into the connection hole 5 of the damper 3. The length of the transmission column 4 is adjustable. The transmission assembly connects the transmission column 4 and the pedal 2 to achieve synchronous rotation. When it is necessary to adjust the foot pedal damping force, first adjust the length of the transmission column 4. If the damping force needs to be increased, extend the transmission column 4 so that more damper 3s can be inserted into the connection hole 5 at its head end. If the damping force needs to be decreased, shorten the transmission column 4 to reduce the number of dampers 3s inserted into the connection hole 5. Then, step on the pedal 2. The pedal 2 rotates around the hinge point and drives the transmission column 4 to rotate synchronously through the transmission assembly. At this time, the dampers 3 inserted with the transmission column 4 work together to produce a damping effect. The more dampers 3 inserted, the greater the overall damping force, and vice versa. This structure changes the number of dampers 3 involved in the operation by adjusting the number of transmission columns 4 inserted into the damper 3 connection holes 5, thereby achieving free adjustment of the damping force and adapting to the personalized needs of different users for the foot pedal resistance of the top flow machine.

[0019] See Figures 1-3 In other embodiments, the transmission assembly includes a half gear 6 and a transmission gear 7. The half gear 6 is fixedly mounted on the pedal 2, and the axis of the half gear 6 is coaxial with the axis of the pedal 2 hinge. The transmission gear 7 is rotatably mounted on the base 1, and the transmission gear 7 is coaxially fixed with the transmission column 4. The transmission gear 7 and the half gear 6 mesh with each other. When the user steps on the pedal 2, the pedal 2 rotates around the hinge point, causing the coaxial half gear 6 to rotate synchronously. The meshing transmission gear 7 rotates accordingly, which in turn causes the transmission column 4, which is coaxial with the transmission gear 7, to rotate synchronously. At this time, the damper 3, which is inserted into the head end of the transmission column 4, generates a damping force, forming foot resistance.

[0020] Furthermore, the diameter of the half gear 6 is larger than that of the transmission gear 7. When the user steps on the pedal 2, the pedal 2 rotates around the hinge point, causing the half gear 6 to rotate synchronously. Since the half gear 6 has a larger diameter, it will drive the transmission gear 7 to rotate at a faster speed during meshing, which in turn drives the coaxial transmission column 4 to rotate rapidly. At this time, the damper 3, which is inserted into the head of the transmission column 4, generates damping force under high-speed rotation, forming foot resistance.

[0021] See Figures 1-3 In another embodiment, multiple dampers 3 are mounted on the base 1 by screws. The screw mounting method for the dampers 3 not only facilitates flexible adjustment of the number of dampers 3 or the spacing of the dampers 3 according to the usage requirements of the top flow machine, but also allows for quick disassembly and replacement when the dampers 3 experience wear or failure, reducing maintenance difficulty.

[0022] Furthermore, a protective sleeve 8 is provided between two adjacent dampers 3, and the protective sleeve 8 is fitted onto the screw. After the screw between adjacent dampers 3 is fitted with the protective sleeve 8, it can, on the one hand, prevent the dampers 3 from directly colliding and rubbing due to vibration or slight displacement during operation, reduce component wear, and extend the service life of the dampers 3; on the other hand, it can fill the gap between adjacent dampers 3, limit the lateral displacement of the dampers 3, ensure that the dampers 3 are always neatly arranged along the preset axis, ensure the accuracy of the insertion of the transmission column 4 head end and the connecting hole 5, and avoid transmission jamming or unstable damping force output due to the displacement of the dampers 3; at the same time, the protective sleeve 8 can also protect the screw, reduce the corrosion of the screw by external dust and moisture, prevent the screw corrosion from affecting the stability of the damper 3 during disassembly, assembly and fixation, further improve the reliability of the overall structure, and meet the needs of long-term use of the top flow machine. The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
