The utility model includes a foot pedal, a foot pedal support rod, a hinge rod, and a connecting rod. The foot pedal support rod is vertically disposed on the back of the foot pedal. The two ends of the hinge rod are connected to the ends of the foot pedal support rod and the connecting rod respectively via hinge pins. The hinge rod is a telescopic rod, and a key is provided at the telescopic joint of the hinge rod to restrict its rotational freedom.

Description

Technical Field

[0001] This utility model relates to the field of electric vehicles, and in particular to an adjustable telescopic mechanism for the foot pedal of the driver's seat of an electric tricycle. Background Technology

[0002] Most existing electric tricycles have a fixed foot pedal structure, mounted at the front like in cars. For the average driver, this usually requires a relatively forward seating position with legs fully extended to reach the brake pedal. This results in a shallow seating depth, especially for shorter drivers, as the position cannot be adjusted to suit their needs. Besides the aforementioned issues of limited seating position, reduced comfort, and safety due to the brake pedal's location, the fixed pedal position also forces the driver's legs to remain extended for extended periods during long journeys, leading to leg fatigue and poor blood circulation, further impacting the driving experience and safety. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] This utility model provides an adjustable telescopic mechanism for the driver's seat foot pedal of an electric tricycle, including a pedal, a pedal support rod, a hinge rod, and a connecting rod. The pedal support rod is vertically arranged on the back of the pedal, and the two ends of the hinge rod are respectively connected to the ends of the pedal support rod and the connecting rod through hinge pins.

[0005] Furthermore, the hinge rod is a telescopic rod, and the multi-sleeve telescopic section of the hinge rod is provided with a protruding key, which restricts the rotational freedom of the hinge rod itself.

[0006] Furthermore, the hinge pin includes a central pin portion, one end of which is a bolt portion and the other end is a fixing nut, and a tightening nut is provided at the pin portion.

[0007] Furthermore, an elastic washer is provided between the tightening nut and the bolt, and tapered locking teeth are machined on the inner end faces of the fixing nut and the tightening nut.

[0008] Furthermore, each end of the hinge rod is provided with a groove plate that mates with the hinge pin.

[0009] Furthermore, a preload spring is provided inside the hinge rod.

[0010] The beneficial effects of this utility model are as follows:

[0011] By incorporating a retractable hinge rod, the distance between the pedal support rod and the connecting rod can be flexibly adjusted, thereby enabling the retraction and adjustment of the pedal position. This improves driving comfort and safety, effectively solving the problem of significant differences in driving experience for drivers of different heights due to the fixed position of the pedals in existing technologies.

[0012] The articulated rod has a key at the extension point of the multi-sleeve, which restricts the rotational freedom of the articulated rod itself, ensuring that the pedal always maintains a stable posture, thus improving driving safety and reliability.

[0013] A preload spring is installed inside the articulated rod, which can provide a certain preload force after the pedal position is adjusted, so that the pedal is kept in the stable position after adjustment, reducing the possibility of the pedal position shifting due to minor vibrations during vehicle operation.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] An adjustable telescopic mechanism for the driver's seat foot pedal of an electric tricycle includes a pedal 1, a pedal support rod 2, a hinge rod 3, and a connecting rod 4. The pedal support rod 2 is vertically disposed on the back of the pedal 1. The two ends of the hinge rod 3 are respectively connected to the ends of the pedal support rod 2 and the connecting rod 4 via hinge pins 5. The hinge rod 3 is a telescopic rod, and a protruding key 31 is provided at the telescopic joint of the hinge rod 3, which restricts the rotational freedom of the hinge rod 3. The pedal support rod 2 vertically fixes the pedal 1, and the hinge rod 3 connects the pedal support rod 2 and the connecting rod 4 via the hinge pins 5 to form a movable integral structure. When it is necessary to adjust the position of the pedal 1, subsequent adjustments to each component will be based on this basic connection relationship, allowing the pedal 1 to change position as the components are adjusted. The telescopic design allows the hinge rod 3 to change its length, thereby adjusting the distance between the pedal support rod 2 and the connecting rod 4, and thus changing the position of the pedal 1; while the convex key 31 ensures that the hinge rod 3 will not rotate during the extension and retraction process, ensuring that the pedal 1 always maintains the correct orientation and a stable working posture.

[0020] The hinge pin 5 includes a central pin portion 501, one end of which is a bolt portion 502, and the other end is a fixing nut 503. A tightening nut 504 is provided at the pin portion 501. An elastic washer 505 is provided between the tightening nut 504 and the bolt portion 502. The elastic washer 505 is compressed during the tightening process of the tightening nut 504, generating elastic deformation, providing a certain buffer and preload for the connection, and reducing the impact of vibration and impact on the connection. The design of the tapered locking teeth 506 increases the friction between the tightening nut 504 and the fixing nut 503 and the connecting parts, further preventing the tightening nut 504 from loosening due to vibration and other factors during vehicle operation, ensuring the reliability of the connection. The inner end faces of the fixing nut 503 and the tightening nut 504 are machined with tapered locking teeth 506. Both ends of the hinge rod 3 are respectively provided with slotted plates 6 that mate with the hinge pin 5. A preload spring 7 is provided inside the hinge rod 3. After the articulated rod 3 is extended and adjusted to the correct position, the preload spring 7 will provide a certain preload force. This preload force can counteract the influence of the small vibrations generated during vehicle operation on the position of pedal 1, so that pedal 1 always remains in the adjusted stable position, thereby improving the accuracy and stability of pedal 1 operation.

[0021] Through the above specific embodiments, those skilled in the art can easily implement this utility model. However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
