Description

Technical Field

[0001] This utility model relates to the field of auxiliary mechanisms in the field of tricycles, specifically to a novel shock-absorbing cushioning seat for electric tricycles. Background Technology

[0002] Electric tricycles are three-wheeled vehicles powered by electricity, typically used for short-distance transport, goods delivery, agricultural operations, and urban transportation. They are generally more environmentally friendly than traditional fuel-powered tricycles because they do not emit exhaust fumes and have lower operating costs.

[0003] Currently, the seats of electric tricycles are generally made of sheet metal and fixed to the frame by welding. When encountering poor road conditions, especially in the fields of rural areas, the ride on bumpy roads can cause the rider to feel swaying from side to side. Since the front and rear shock absorbers cannot completely eliminate stress, the impact force will be transmitted to the driver through the frame and seat, resulting in a poor riding experience and also posing certain safety hazards.

[0015] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0016] Example 1:

[0017] This embodiment proposes a novel shock-absorbing and cushioning seat for an electric tricycle, comprising a seat body, which is hollow and has a receiving cavity of a predetermined working size. The key feature is that a support connecting component is provided at a predetermined working position within the hollow receiving cavity of the seat. This support connecting component has a predetermined working size and supporting force, and can perform corresponding connection and limiting operations. A cushioning component is movably connected to the lower position of the support connecting component in the working direction. The cushioning component has a predetermined working length and supporting force, with one end abutting against the support connecting component and the other end connected to the vehicle frame. The support connecting component includes two parts: a connecting lug 3 and a support frame 5. The connecting lug 3 is placed on the inner wall surface of the hollow receiving cavity of the seat, has a predetermined working size, and is multiple in number, symmetrically distributed on the inner wall surface of the hollow receiving cavity of the seat, and can perform corresponding limiting and connection operations. In a further preferred embodiment, there are four lugs, distributed at the four corners of the hollow receiving cavity of the seat and positioned at the middle position in the vertical working direction of the seat. The support frame 5 has a predetermined working size and supporting force, and is connected to the connecting lug 3 via a pin 6, enabling corresponding limiting and transmission operations. The working surface of the connecting lug 3 has a through hole adapted to the working size of the pin 6, and the connecting lug 3 is U-shaped. The working surface of the support frame 5 also has a through hole of a predetermined working size. In actual operation, the support frame 5 is first inserted into the recessed cavity of the connecting lug 3, and then the pin 6 passes through the through hole provided by the connecting lug 3 and the support frame 5, and is fixed in the hollow receiving cavity of the seat bucket through the cotter pin 4. The buffer assembly includes two components: a positioning unit and a buffer unit. The positioning unit is placed in the hollow receiving cavity of the seat bucket, has a predetermined working size, and can perform corresponding load-bearing and limiting operations. The buffer unit is placed on the working surface of the positioning unit, has a predetermined working size and supporting force, and one end abuts against the support frame 5, enabling corresponding buffering operations.

[0018] Example 2:

[0019] Based on Embodiment 1, the positioning unit comprises two components: a base 16 and a base bracket 15. The base 16 is placed within the hollow receiving cavity of the seat bucket and connected to the frame body, having a predetermined working size and load-bearing space, and can perform corresponding limiting and load-bearing operations. The base bracket 15 is connected to the base 16 via connecting screws 13 and locked in place by fastening nuts 14, placed on the working surface of the base 16, having a predetermined working size, and there are multiple such brackets, which can perform corresponding limiting operations. In a further preferred embodiment, there are four base brackets 15, and their working positions correspond to the working positions of the support frame 5. The buffer unit comprises three components: a lead screw 10, a stress spring 9, and a damping pad assembly. The lead screw 10 is placed on the working surface of the base 16 and connected to the base bracket 15 via fastening nuts 14, having a predetermined working size and supporting force, and there are multiple such brackets. The stress spring 9 is sleeved around the lead screw 10, having a predetermined working size damping property, and there are multiple such springs, which can perform corresponding shock absorption operations. The cushioning assembly is sleeved on the outside of the lead screw 10 and placed at both ends of the stress spring 9. Multiple cushioning assemblies are present to perform corresponding buffering and transmission operations. In a further preferred embodiment, the number of lead screws 10, stress springs 9, and cushioning assemblies matches the number of base supports 15. The cushioning assembly includes an upper iron hoop 7, an upper rubber buffer pad 8, a lower rubber buffer pad 11, and a lower iron hoop 12. The upper iron hoop 7 and the upper rubber buffer pad 8 are sequentially sleeved on the outside of the lead screw 10 and placed at one end of the lead screw 10 near the support frame 5, with the upper iron hoop 7 abutting against the support frame 5. The lower rubber buffer pad 11 and the lower iron hoop 12 are sequentially sleeved on the outside of the lead screw 10 and placed at one end of the lead screw 10 near the base support 15, with the lower iron hoop 12 abutting against the base support 15. The working surface of the seat bucket is provided with a seat cushion 2 and a seat bucket armrest 1. The seat cushion 2 has a predetermined working size, and the seat bucket armrest 1 is placed on both sides of the seat cushion 2. In a further preferred embodiment, the buffer unit is placed between the support frame 5 and the base 16. The base bracket 15 is U-shaped and has multiple through holes on its working surface. The lead screw 10 passes through the through holes of the base bracket 15 and is locked in place by a fastening nut 14. A predetermined working distance is maintained between the lead screw 10 and the support frame 5. The straight-line distance gap between the lead screw 10 and the support frame 5 is less than the total thickness of the upper iron hoop 7 plus the upper rubber buffer pad 8, but greater than the total thickness of the upper rubber buffer pad 8. In actual operation, after the lead screw 10 is locked in place, the lower iron hoop 12 and the lower rubber buffer pad 11 are first fitted over the lead screw 10, then the stress spring 9 is fitted over the lead screw 10, and finally the upper rubber buffer pad 8 and the upper iron hoop 7 are fitted over the lead screw 10.

[0020] Based on the above embodiments, the assembly method of this utility model is as follows: the support frame 5 is assembled with the connecting lug 3 by means of pins 6 and cotter pins 4, the connecting screws 13 fix the base bracket 15 and the base 16 together, one end of the screw rod 10 is fixed on the base bracket 15, the middle part passes through the upper iron hoop 7, the upper rubber buffer pad 8, the stress spring 9 and the screw rod 10, and the top is fixed to the support frame 5 by means of fastening nuts 14.

[0021] When encountering bumpy road sections while driving, the driver sits on the seat and applies a downward force to the seat. The force is transmitted from the seat to the support frame 5 via the connecting lug 3. The support frame 5 will move downward under the force, and the kinetic energy will be transmitted to the stress spring 9 via the rubber buffer pad. The stress spring 9 will compress its stroke, converting the kinetic energy it receives into deformation energy inside the elastic body, which will be gradually consumed and dispersed, thereby offsetting this part of the force.

[0022] This energy absorption and dissipation process reduces the impact on the driver when the vehicle encounters bumpy and rough roads, thereby improving driver comfort. After the stress is relieved, the seat cushion will automatically return to its original shape.

[0023] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
