Description

Technical Field

[0001] The invention relates to the field of tricycles, in particular to a suspension mechanism for a fully enclosed electric tricycle. Background Art

[0002] The fully enclosed electric tricycle uses high-tech composite materials to build the body, which has the advantages of corrosion resistance, impact resistance, light weight, and long life. It is widely used in the aviation industry, shipbuilding industry, and environmental protection industry. The fully enclosed electric tricycle frame is connected with thickened steel, and the super-strong steel plate is used for shock absorption and perfect welding. The glass is equipped with 360° electric wipers to ensure safe riding in rainy and snowy weather. The interior of the fully enclosed electric tricycle is not as perfunctory as some opportunistic manufacturers. It is made of double-sided light without seams, and the beauty is greatly improved. The fully enclosed electric tricycle is so practical that the scope of use is several times larger than that of the open electric tricycle, and the user population is also moving closer to the masses.

[0003] However, compared with open electric tricycles, the main purpose of fully enclosed electric tricycles is to carry people, so they have relatively high safety requirements and better shock absorption performance. In order to save costs, existing fully enclosed electric tricycles have poor basic shock absorption effects, weak anti-body rollover capabilities, and poor user experience. At the same time, general users have no idea of ​​the load capacity, which often exceeds the load capacity of the tricycle itself. Long-term use will shorten the service life of the tricycle, and there are no reminders to prevent overloading. Summary of the invention

[0004] The purpose of the present invention is to provide a suspension mechanism for a fully enclosed electric tricycle to solve the problem raised in the above background technology. However, compared with an open electric tricycle, the main purpose of a fully enclosed electric tricycle is to carry people, and relatively speaking, a higher safety factor and better shock absorption performance are required. In order to save costs, the existing fully enclosed electric tricycles have poor basic shock absorption effect, weak anti-body rollover ability, and poor use and passenger experience. At the same time, general users have no way of understanding the load capacity, which often exceeds the load capacity of the tricycle itself. Long-term use will shorten the service life of the tricycle, and there is no reminder to prevent overloading by weighing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a suspension mechanism for a fully enclosed electric tricycle, comprising a suspension box, the tops of both sides of the suspension box are fixedly connected to a first rotating rod, the bottoms of both sides of the suspension box are fixedly connected to a second rotating rod, the suspension box is rotatably connected to one side of the first support plate through the first rotating rod, the other side of the first support plate is hinged with a side plate, the side of the side plate away from the first support plate is hinged to one side of the second support plate, the other side of the second support plate is rotatably connected to the bottom of the suspension box through the second rotating rod, one side of the side plate is fixedly connected to one end of the first shock-absorbing spring, the other side of the first shock-absorbing spring One end is fixedly connected to the middle part of one side of the suspension box, a groove is opened in the middle part of the suspension box, the suspension box is slidably connected to the bottom of the T-shaped support block through the groove, the bottom end of the T-shaped support block is fixedly connected to one end of the second shock-absorbing spring, the other end of the second shock-absorbing spring is fixedly connected to the bottom end of the groove, a pressure switch is fixedly installed at the bottom of the groove, an alarm is fixedly installed at the top part of one side of the T-shaped support block, a connecting seat is fixedly connected to the bottom of one side of the suspension box, the connecting seat is threadedly connected to one side of the mounting frame through bolts, a wheel axle is inserted and connected to the middle part of the side plate, and both ends of the wheel axle are rotatably connected to the wheel through bearings.

[0006] As a preferred technical solution of the present invention, a battery box is fixedly mounted on the surface of one side of the T-shaped support block, a battery is installed inside the battery box, and the alarm is electrically connected to the battery via a pressure switch.

[0007] As a preferred technical solution of the present invention, the T-shaped support block is made of stainless steel welded in one piece, and a plurality of threaded holes are formed on the top of the T-shaped support block.

[0008] As a preferred technical solution of the present invention, a connecting rod is fixedly connected to one side of the mounting frame, shock-absorbing seats are fixedly connected to both ends of the other side of the mounting frame, the shock-absorbing seats are fixedly connected to the bottom of the shock-absorbing spring column, and the top of the shock-absorbing spring column is fixedly connected to the top of the other side of the T-shaped support block.

[0009] As a preferred technical solution of the present invention, both sides of the bottom of the T-shaped support block are fixedly connected to limit blocks, and the surface of the limit blocks is sprayed with lubricating oil.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The first shock-absorbing spring, the second shock-absorbing spring and the shock-absorbing spring column are set to buffer and damp the wheel stretching part, the T-shaped support block part and the mounting frame part respectively, which has a better effect. At the same time, the first support plate, the second support plate and the side plate are added. When one of the wheels rolls, the wheel connected on the other side will also roll in the same direction under the connection of the suspension box, reducing the probability of the vehicle body rolling over, and the experience effect is better;

[0012] 2. Set up a T-shaped support block, groove, pressure switch and alarm. When installed, the T-shaped support block is connected to the bottom of the frame. When the vehicle body is bearing weight, the T-shaped support block will transfer part of the pressure to the pressure switch through the second shock-absorbing spring. When the bearing pressure exceeds a certain value, the pressure switch will control the alarm to remind the user that the load is too heavy and to use it with caution. This avoids damage to the vehicle body caused by overloading for a long time without the user's knowledge, thereby extending the service life of the tricycle. BRIEF DESCRIPTION OF THE DRAWINGS
