Abstract
The invention designs a seat damping mechanism for a portable vehicle, which comprises a frame, a seat and a seat support rod. The invention provides a shock absorption mechanism of a convenient vehicle, which is arranged at the joint of a saddle and a frame, so that the shock absorption mechanism of the frame and wheels can be simplified or even replaced.
Description
Technical Field
The present invention relates to a seat cushioning mechanism for a portable vehicle.
Background
The electric bicycle is widely applied as one of travel modes of simple, convenient and environment-friendly travel of people, the endurance mileage of the electric bicycle becomes the main competitive factor and attention factor of electric bicycle market competition and consumer purchase, and in the endurance mileage, the weight of the electric bicycle body has great influence on the endurance mileage, so that the lighter the weight of the electric bicycle body, the longer the endurance mileage, and the greater the product competitiveness.
In the damping mechanism of the traditional electric bicycle, soft connection, such as spring connection, is generally established between the frame and wheels of the electric bicycle, so that jolt vibration caused by road conditions at the ends of the wheels is filtered by the springs and then transmitted to the frame, and the aim of damping is achieved. The structural part has large weight, and the filtering vibration effect is general only by the spring, and the filtering effect on the small-intensity vibration of the road surface in the driving process is poor.
Disclosure of Invention
The invention aims to overcome the problems in the prior art and provide a seat damping mechanism for a portable vehicle. The double-force elastic assembly consists of a shell, a spring, a small sealing ring, a large sealing ring and a supporting rod, wherein the top of the shell is formed by a through hole, the lower part of the supporting rod of the saddle is nested in the through hole, the small sealing ring is embedded in the inner wall of the through hole, a limit nut is arranged at the bottom end of the supporting rod of the saddle, the bottom of the limit nut is connected with the spring, the other end of the spring is connected with the head part of the supporting rod nested in the lower part of the shell, the large sealing ring is embedded on the outer wall of the head part of the supporting rod, and the head part of the supporting rod is connected with the bottom of the shell by a locking nut sleeved on the supporting rod. 2 small sealing rings are embedded on the inner wall of the through hole at the top of the shell. 2 large sealing rings are embedded on the outer wall of the head part of the support rod. The invention has the advantages that the damping mechanism is arranged at the joint of the saddle and the frame, so that the damping mechanism of the frame and the wheels can be simplified or even replaced.

Detailed Description
In order to make the present application better understood by those skilled in the art, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and the described embodiments are obviously only embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
The seat damping mechanism for the portable vehicle comprises a frame 1, a seat 2 and a seat support rod 3, and is characterized in that the bottom of the seat support rod is connected with a double-force elastic assembly 4, and the bottom of the double-force elastic assembly is fixedly connected with the frame. The double-force elastic assembly is composed of a shell 5, a spring 6, a small sealing ring 7, a large sealing ring 8 and a supporting rod 9, wherein the top of the shell is formed by a through hole 10, the lower part of a saddle supporting rod is nested in the through hole, the small sealing ring is embedded in the inner wall of the through hole, a limit nut 11 is arranged at the bottom end of the saddle supporting rod, the bottom of the limit nut is connected with the spring, the other end of the spring is connected with the head part of the supporting rod nested in the lower part of the shell, the large sealing ring is embedded in the outer wall of the head part of the supporting rod, and the head part of the supporting rod is connected to the bottom of the shell by a locking nut 12 sleeved on the supporting rod. 2 small sealing rings are embedded on the inner wall of the through hole at the top of the shell. 2 large sealing rings are embedded on the outer wall of the head part of the support rod.
When the vehicle is in actual use, in the running process of the vehicle, the wheels vibrate due to the factors such as road conditions and the like, vibration stress is transmitted to the vehicle frame, and meanwhile, the vehicle frame is rigidly connected with the supporting rods, so that the supporting rods receive axial force generated by vibration of the wheels in the running process of the wheels. Because the supporting rod and the shell are sealed through the large sealing ring and can slide relatively with the shell, when the supporting rod is stressed, the supporting rod extrudes the spring, and meanwhile, because the large sealing ring, the small sealing ring and the shell form a sealing cavity, when the supporting rod is stressed to extrude the spring, the supporting rod compresses the gas sealed in the shell, and at the moment, the force applied by the supporting rod of the saddle is the elasticity of the spring and the air pressure intensity inside the shell. The effective sealing area formed by the support rod and the large sealing ring is different from the effective area formed by the saddle support rod and the small sealing ring, so that the force born by the saddle support rod, namely the force felt by a driver, is reduced, and the purpose of shock absorption is achieved.
