Description

Technical Field

[0001] This utility model relates to the field of tricycle technology, specifically to an electric reversing tricycle with a rocking function. Background Technology

[0002] The difference between current electric bicycles and ordinary bicycles is that electric bicycles also include a drive structure and a drive battery. Other components, such as shopping baskets or those carrying other people, are arranged on the back seat, making it impossible to constantly observe the safety of goods or passengers. To solve the above problems, existing electric bicycles place the shopping basket or child seat at the front, so that the rider can always observe the situation of goods or children in front. For example, patent application number CN202320945122.2 discloses a three-wheeled lithium-ion electric bicycle, which uses a single handlebar to control the steering of both front wheels at the same time. This can easily cause the linkage to lock up and become unable to rotate. At the same time, its front rack is welded and fixed to the frame and cannot be removed, making it inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple, stable, safe, and easy-to-use electric reversing tricycle.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An electric reversing tricycle with a rocking function includes a tricycle frame, a seat post, a front wheel, and a rear wheel. The seat post is fixed to the tricycle frame, and the rear wheel is connected to the rear end of the tricycle frame. Telescopic frames are retractably connected to the left and right sides of the front end of the tricycle frame. A handlebar is rotatably connected to the outer side of the telescopic frame. The front wheel is connected to the handlebar, and a rocking linkage rod is hinged to the handlebar. A locking plate is fixed to the tricycle frame, and locking components are also installed on the left and right sides of the front end of the tricycle frame. A buckle assembly is also placed on the telescopic frame.

[0006] A further technical solution is that the buckle assembly includes a buckle seat and a buckle rod. A pin is fixed on the buckle seat, and the buckle rod is rotatably connected to the pin. A torsion spring is also sleeved on the left and right sides of the pin. The buckle rod can rotate within the buckle seat around the pin axis. When rotating, the outer end of the buckle rod is pressed down, while the hook in the middle of the buckle rod is raised. In this way, the shelf, child seat, or other front basket that was originally buckled on the buckle assembly can be released and taken out. After being taken out, the buckle rod is reset because the torsion springs are still sleeved on the left and right sides of the pin.

[0007] A further technical solution is that flanges are distributed on the left and right inner sides of the buckle seat. One end of the torsion spring abuts against the flange, and the other end is sleeved on the buckle rod. When the buckle rod rotates downward, because one end of the torsion spring is sleeved on the buckle rod, the downward rotation of the buckle rod causes the torsion spring sleeved on the inner end of the buckle rod to be lifted upward. Because the other end of the torsion spring abuts against the flange, the torsion spring is twisted and deformed. When the buckle rod is released, the buckle rod returns to its original position due to the elasticity of the torsion spring.

[0008] A further technical solution is that a locking seat is fixed on the tricycle frame, and the locking plate is fixed on the side end of the locking seat. The locking plate is more secure than if it were fixed on the tricycle frame.

[0009] A further technical solution is that the front end of the buckle seat is also provided with a slot for placing the front side of the shelf or child seat, so as to prevent the shelf or child seat from moving back and forth and can only be taken up and down.

[0010] A further technical solution is that the buckle seat is also provided with through holes, and the buckle rod is also fixed with a limiting tube. The limiting tube is a hollow structure. When the middle hole of the limiting tube is aligned with the through hole, a limiting pin can be inserted. After insertion, the buckle rod cannot be rotated. In this way, the shelf or child seat can be firmly restricted in the buckle assembly and cannot be disengaged.

[0011] A further technical solution is that the locking component penetrates the tricycle frame and the telescopic frame. The telescopic frame also has limiting grooves distributed on both sides. The locking component is also fixed with a locking block. After the locking component penetrates the tricycle frame, the telescopic frame can freely extend and retract inside and outside the tricycle frame because the telescopic frame also has limiting grooves distributed on both sides. When the telescopic frame is adjusted to the required position, the locking component locks the locking block outward and locks the tricycle frame and the telescopic frame.

[0012] The beneficial effects of this utility model are as follows: This utility model provides an electric reversing tricycle with a rocking function, which adopts left and right double handlebars. Through a rocking linkage rod, rotating either handlebar will cause the other handlebar to rotate, making operation more stable and comfortable, and direction changes smoother. The tricycle frame is equipped with locking plates, and the telescopic frame has buckle components. When a storage rack, child seat, or other front basket needs to be placed on the vehicle, it can be quickly installed using the locking plates and buckle components, making assembly and disassembly more convenient. The telescopic frame and tricycle frame are adjustable in length and height, allowing for selection according to individual needs, making riding more comfortable. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] See Figures 1 to 6As shown, an electric reversing tricycle with a rocking function includes a tricycle frame 2, a seat rod 3, a front wheel 7, and a rear wheel 1. The seat rod 3 is fixed to the tricycle frame 2, and the rear wheel 1 is connected to the rear end of the tricycle frame 2. Telescopic frames 5 are telescopically connected to the left and right sides of the front end of the tricycle frame 2. Handlebars 8 are rotatably connected to the outside of the telescopic frames 5. The front wheel 7 is connected to the handlebars 8. A rocking linkage rod 9 is hinged to the handlebars 8. A locking plate 11 is fixed on the tricycle frame 2. Locking components 12 are also installed on the left and right sides of the front end of the tricycle frame 2. A buckle assembly 6 is also placed on the telescopic frames 5.

[0023] The buckle assembly 6 includes a buckle seat 61 and a buckle rod 63. A pin 68 is fixed on the buckle seat 61, and the buckle rod 63 is rotatably connected to the pin 68. Torsion springs 67 are also sleeved on the left and right sides of the pin 68. The buckle rod 63 can rotate within the buckle seat 61 around the axis of the pin 68. When rotating, the outer end of the buckle rod 63 is pressed down, while the hook part in the middle of the buckle rod 63 is raised. In this way, the shelf, child seat or other front basket that was originally buckled on the buckle assembly 6 can be unbuckled and taken out. After being taken out, the buckle rod 63 is reset because the pin 68 is also sleeved on the left and right sides. The buckle seat 61 has flanges 66 distributed on its left and right inner sides. One end of the torsion spring 67 abuts against the flange 66, and the other end is sleeved on the buckle rod 63. When the buckle rod 63 rotates downward, because one end of the torsion spring 67 is sleeved on the buckle rod 63, the downward rotation of the buckle rod 63 causes the torsion spring 67 sleeved on the inner end of the buckle rod 63 to rise. Because the other end of the torsion spring 67 abuts against the flange 66, the torsion spring 67 twists and deforms. When the buckle rod 63 is released, the elasticity of the torsion spring 67 causes the buckle rod 63 to return to its original position. A locking seat 10 is fixed on the tricycle frame 2, and a locking plate 11 is fixed on the side end of the locking seat 10. The locking plate 11 is more secure than being fixed on the tricycle frame 2. The buckle seat 61 also has a slot 62 at its front end for placing a storage rack or the front side of a child seat, preventing the storage rack or child seat from moving back and forth and allowing it to be taken up and down. The buckle seat 61 also has through holes 64, and the buckle rod 63 is fixed with a limiting tube 65. The limiting tube 65 is a hollow structure. When the middle hole of the limiting tube 65 is aligned with the through hole 64, a limiting pin can be inserted. After insertion, the buckle rod 63 cannot rotate, so the shelf or child seat can be firmly restricted in the buckle assembly 6 and cannot be released. The locking member 12 passes through the tricycle frame 2 and the telescopic frame 5. The telescopic frame 5 also has limiting grooves 14 on both sides. The locking member 12 is also fixed with a locking block 13. After the locking member 12 passes through the tricycle frame 2, the telescopic frame 5 can move freely inside and outside the tricycle frame 2 because of the limiting grooves 14 on both sides of the telescopic frame 5. When the telescopic frame 5 is adjusted to the desired position, the locking member 12 locks, causing the locking block 13 to move outward and lock the tricycle frame 2 and the telescopic frame 5.

[0024] In this embodiment, there are two front wheels 7 and one rear wheel 1. When riding, both hands hold the handlebars 8 on the left and right sides respectively, and then pedal or drive forward. When turning, both hands hold the handlebars 8 on the left and right sides to turn at the same time. Since the handlebars 8 on both sides are linked by the swing linkage rod 9, no matter how one side of the handlebar 8 rotates, the other side will rotate synchronously to adjust the angle. When it is necessary to place the storage rack, child seat or other front basket on the tricycle, firstly, the locking piece 11 is connected to the storage rack, child seat or other front basket by a pin or rod, and then the buckle rod 63 is rotated so that the storage rack, child seat or other front basket can be inserted into the slot 62 and be buckled with the buckle rod 63. In this way, the storage rack, child seat or other front basket can be quickly and safely placed on the tricycle frame 2 and the telescopic frame 5.

[0025] The tricycle frame 2 is also connected to pedals 4, and a battery drive assembly 15 is connected to the tricycle frame 2 and the rear wheel 1. The battery drive assembly 15 can drive the rear wheel 1 forward, while the pedals 4 are conventional pedal structures and can be moved forward by human power.
