Description

Technical Field

[0001] This utility model relates to the field of tricycle technology, and in particular to an electric riding hand-pushed tricycle. Background Technology

[0002] Trolleys, with their advantages of simple maintenance, convenient operation, and compact structure, have become a widely used means of transportation, adaptable to various terrains. Based on their power source, trolleys are mainly divided into two categories: human-powered and electric-powered.

[0003] Manual trolleys rely entirely on human power and perform exceptionally well in small-scale, light-load, and short-distance transportation scenarios, offering flexibility and the ability to "stop and go." However, when long-distance transportation is required, their reliance on pure human power becomes a significant drawback, manifesting as limited load capacity, lower transportation efficiency, and high labor intensity. Electric trolleys, on the other hand, are driven by motors and are characterized by labor-saving, high efficiency, and environmental friendliness, making them particularly suitable for long-distance or heavier-load transportation needs. However, when applied to short-distance, light-load, and low-frequency scenarios, their flexibility and operability are inferior to manual trolleys. Because a driver's position is usually required, traditional electric trolleys typically have a longer body structure, resulting in a larger turning radius, greater space occupation, and further limiting their flexibility. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide an electric riding tricycle that can freely switch between manual and electric pushing, meet the needs of long and short distance cargo transportation, reduce labor intensity, reduce space occupation, and improve flexibility and operability.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An electric riding tricycle, including a frame, characterized in that...

[0007] The front of the vehicle frame is equipped with an electric drive front wheel device;

[0008] A rear wheel assembly and a seat mounted on the rear wheel assembly are provided at the rear of the frame. The rear wheel assembly is connected to the frame via an adjustment mechanism, so that the distance between the rear wheel assembly, the seat and the rear end of the frame is adjustable.

[0009] The rear end of the frame is provided with a handlebar assembly, which includes two handles located on both sides in front of the seat.

[0010] Preferably, the adjustment mechanism includes a longitudinal guide rail, a longitudinal slide bar, and a limiting member. The longitudinal guide rail is fixed to the vehicle frame, the longitudinal slide bar is constrained by the longitudinal guide rail, the rear end of the longitudinal slide bar is fixed to the rear wheel assembly, and adjustment holes are provided at both the front and rear of the longitudinal slide bar. A limiting hole is provided on the longitudinal guide rail, and the limiting member passes through the limiting hole and one of the adjustment holes.

[0011] Preferably, the adjustment hole at the front includes a plurality of equally spaced front fine-tuning holes, and the adjustment hole at the rear includes a plurality of equally spaced rear fine-tuning holes.

[0012] Preferably, the longitudinal guide rail is made of sleeve, channel steel or angle steel; the limiting component is a pin or bolt.

[0013] Preferably, the rear wheel assembly includes:

[0014] A bushing, which is vertically arranged and fixedly connected to the rear end of the longitudinal slide rod; a support rod is fixed to the rear part of the bushing, and the seat is arranged on the upper end of the support rod;

[0015] A rotating shaft, which is rotatably mounted within the bushing;

[0016] A wheel fork is fixedly connected to the bottom end of the slewing shaft, and a rear wheel is installed inside the wheel fork; foot pedals are fixedly installed on both outer sides of the wheel fork.

[0017] Preferably, the rotary shaft is rotatably mounted in the bushing via a bearing.

[0018] Preferably, both the seat and the longitudinal slide bar are located on the longitudinal centerline.

[0019] Preferably, a cargo bed is mounted on the frame, and the front end of the cargo bed is hinged to the front end of the frame.

[0020] Preferably, a hook is installed at the rear end of the truck bed, the hook being used to connect or separate the rear end of the truck bed from the vehicle frame.

[0021] Preferably, the electric drive front wheel device includes:

[0022] A drive axle, with front wheels mounted at both ends of the drive axle;

[0023] A drive motor, the output shaft of which is connected to the power input end of the drive axle.

[0024] After adopting the above technical solution, the beneficial effects of this utility model are:

[0025] The electric riding tricycle of this application includes a frame, an electric drive front wheel device installed at the front of the frame, a rear wheel device and a seat mounted on the rear wheel device at the rear of the frame, and the rear wheel device is connected to the frame through an adjustment mechanism, so that the distance between the rear wheel device and the seat and the rear end of the frame is adjustable.

[0026] This application includes two usage modes: electric riding and manual pushing. When choosing to ride, the user adjusts the mechanism to move the rear wheel backward, increasing the distance between it and the frame, making it easier for the user to sit on the seat. The user then uses the electric drive front wheel to propel the vehicle. This meets the needs of long-distance transportation, reduces labor intensity, and improves transportation efficiency.

[0027] The rear of the frame houses the handlebar assembly, which includes two handlebars located on either side in front of the seat. When manually pushing, the user moves the rear wheel assembly forward, reducing the distance between it and the frame. This allows the user to stand behind the frame and push the electric tricycle slowly using the two handlebars. This meets the requirements for short-distance transport, enabling "stop and go" functionality. Simultaneously, it shortens the overall length of the tricycle, reduces the turning radius, and improves maneuverability and flexibility.

[0028] In this application, the rear wheel assembly includes a bushing, a swivel axle, and a wheel fork. The bushing is vertically positioned and fixedly connected to the rear end of a longitudinal slide rod. A support rod is fixedly attached to the rear of the bushing, and the seat is positioned on the upper end of the support rod. The swivel axle is rotatably mounted inside the bushing. The wheel fork is fixedly connected to the bottom end of the swivel axle, and a rear wheel is installed inside the wheel fork. Foot pedals are fixedly mounted on the outer sides of the wheel fork. When the user rides the electric bicycle, the user sits on the seat with both feet on the foot pedals. By applying different directions of force with both feet, the user rotates the wheel fork, causing the rear wheel to rotate and changing the direction of travel, thus achieving foot-controlled steering. The user's hands can focus on controlling the speed, braking, or maintaining balance. It is also suitable for users who can control the bicycle with one hand while still steering with both feet, improving the convenience of riding control. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0046] like Figures 1 to 5 As shown, the present invention includes a frame 1, an electric front wheel device 2 is mounted on the front of the frame 1, a rear wheel device 4 and a seat 45 mounted on the rear wheel device 4 are arranged at the rear of the frame 1, and the rear wheel device 4 is connected to the frame 1 through an adjustment mechanism 3, so that the distance between the rear wheel device 4 and the seat 45 and the rear end of the frame 1 is adjustable.

[0047] In this application, the electric front wheel device 2 is an electric drive device, which includes a drive axle 21 and a drive motor 23. The two ends of the drive axle 21 are respectively equipped with front wheels 22. The output shaft of the drive motor 23 is connected to the power input end of the drive axle 21. The drive motor 23 is controlled by the electronic control device 7. When the drive motor 23 rotates, it drives the two front wheels 22 to rotate simultaneously through the drive axle 21, thereby moving the electric riding tricycle of this application and meeting the driving requirements when riding.

[0048] This application includes two usage modes: electric riding and manual pushing. When choosing to ride, the user moves the rear wheel assembly 4 backward via the adjustment mechanism 3, increasing the distance between it and the frame 1, making it easier for the user to sit on the seat 45. The user then rides the bicycle via the electric drive front wheel assembly 2. This meets the needs of long-distance transportation, reduces labor intensity, and improves transportation efficiency.

[0049] A handlebar assembly 5 is located at the rear of the frame 1, and the handlebar assembly 5 includes two handlebars 51 located on both sides in front of the seat 45. When manually pushing is selected, the user moves the rear wheel assembly 4 forward, shortening the distance between it and the frame 1, making it easier for the user to stand behind the frame 1 and push the electric tricycle slowly using the two handlebars 51. This meets the requirements for short-distance transportation, enabling "stop and go"; at the same time, it shortens the overall length of the application, reduces the turning radius, and improves operability and flexibility.

[0050] The adjustment mechanism 3 includes a longitudinal guide rail 31, a longitudinal slide bar 32, and a limiting member 33. The longitudinal guide rail 31 is fixed to the frame 1, the longitudinal slide bar 32 is constrained by the longitudinal guide rail 31, and the rear end of the longitudinal slide bar 32 is fixed to the rear wheel device 4. The longitudinal slide bar 32 is provided with adjustment holes 321 at both the front and rear. The longitudinal guide rail 31 is provided with a limiting hole 311, and the limiting member 33 passes through the limiting hole 311 and one of the adjustment holes 321.

[0051] Preferably, the longitudinal guide rail 31 is made of sleeve, channel steel or angle steel; the limiting element 33 is a pin or bolt.

[0052] The adjustment hole 321 at the front includes several equally spaced front fine-tuning holes, and the adjustment hole 321 at the rear includes several equally spaced rear fine-tuning holes. When riding, in order to facilitate the user sitting on the seat 45, it is necessary to align the limiting hole 311 with the front fine-tuning holes. At this time, the limiting member 33 passes through the limiting hole 311 and one of the front fine-tuning holes. By setting several front fine-tuning holes, the distance between the frame 1, the rear wheel assembly 4, and the seat 45 can be finely adjusted while meeting the requirements of riding installation, satisfying the usage requirements of users of different body types and improving user comfort.

[0053] Similarly, when manually pushing, in order to make it easier for the user to hold the handle 51, the limiting hole 311 needs to be matched with the rear fine adjustment hole. When the limiting hole 311 is matched with one of the rear fine adjustment holes, the distance between the frame 1, the rear wheel device 4 and the seat 45 can be finely adjusted according to the user's pushing requirements, so as to meet the usage requirements of users of different body types and improve the comfort of use.

[0054] The rear wheel assembly 4 includes a bushing 41, a slewing shaft 42, and a wheel fork 43. The bushing 41 is vertically arranged and fixedly connected to the rear end of the longitudinal slide bar 32. A support rod is fixed to the rear of the bushing 41, and the seat 45 is arranged on the upper end of the support rod. The slewing shaft 42 is rotatably installed inside the bushing 41. The wheel fork 43 is fixedly connected to the bottom end of the slewing shaft 42, and a rear wheel 44 is installed inside the wheel fork 43. Foot pedals 46 are fixedly arranged on both outer sides of the wheel fork 43.

[0055] When the user rides the electric bike, the user sits on the seat 45 with both feet on the pedals 46. By applying force in different directions with both feet, the user can rotate the wheel fork 43, which in turn rotates the rear wheel 44, changing the direction of travel and achieving foot-controlled steering. The user's hands can focus on controlling the speed, braking, or maintaining body balance. It is also suitable for users to control the bike with one hand while still using both feet to steer, improving the convenience of riding control.

[0056] like Figure 2 , Figure 6 As shown, preferably, the slewing shaft 42 is rotatably mounted inside the bushing 41 via bearings, and the seat 45 and the longitudinal slide bar 32 are both located on the longitudinal centerline. The bushing 41 is fixed, and the slewing shaft 42 inside it can rotate around its axis. During the rotation of the slewing shaft 42, it can drive the wheel fork 43 to rotate around the axis, thereby driving the rear wheel 44 to rotate, achieving the purpose of reversing direction.

[0057] Preferably, the wheel fork 43 includes a pivot connection portion 431 and a wheel axle mounting portion 432; the pivot connection portion 431 is fixedly connected to the bottom end of the rotary shaft 42, and the wheel axle mounting portion 432 is located behind the pivot connection portion 431 along the length direction of the frame 1. The rearward location of the wheel axle mounting portion 432 allows the center of gravity of this application to shift rearward, reducing the risk of tipping over and enhancing stability.

[0058] like Figure 1 , Figure 7 As shown, a truck bed 6 is mounted on the frame 1. The front end of the truck bed 6 is hinged to the front end of the frame 1. A hook 61 is mounted on the rear end of the truck bed 6. The hook 61 is used to connect or separate the rear end of the truck bed 6 from the frame 1. The hook 61 is rotatably mounted on the truck bed 6, and its hook is used to connect with the frame 1.

[0059] When the electric riding tricycle of this application is being ridden or manually pushed, the rear end of the bucket 6 is connected to the frame 1 by the hook 61 to prevent it from tipping forward and to enhance stability; when unloading is required, the hook 61 is separated from the frame 1 to meet the requirements of unloading the bucket 6 by tipping it forward.

[0060] Preferably, a cover plate 11 is installed on the frame 1. The cover plate 11 protects the drive axle 21, drive motor 23 and electronic control device 7 installed on the frame 1 to prevent material leakage in the truck bed 6 from affecting the normal use of each component.

[0061] Based on actual site conditions, this application can be used in two ways: electric riding and manual pushing. When riding electric, the user pulls the longitudinal slide bar 32 backward. Through the cooperation of the longitudinal slide bar 32, the longitudinal guide rail 31, and the limiting member 33, the distance between the rear wheel 44 and the frame 1 is extended. After adjustment, the user sits on the seat 45, holds the handlebars 51 with both hands, and drives the front wheel 22 to move electrically through the drive motor 23. When manual pushing is required, the longitudinal slide bar 32 is operated in the opposite direction to shorten the distance between the rear wheel 44 and the frame 1. After adjustment, the user holds the handlebars 51 and pushes the application manually.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
