Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, specifically relating to an electric tricycle with an adjustable backrest. Background Technology

[0002] Electric tricycles with adjustable backrests are primarily designed to improve the comfort of riders and passengers. This design is particularly suitable for those who need to use electric tricycles for extended periods, whether for commuting, delivery, or leisure. By adjusting the backrest angle, users can find the most comfortable seating position to reduce fatigue from long rides. Furthermore, this design is also very useful for the elderly or those with mobility issues, as it makes getting on and off the tricycle easier and provides better support and comfort while riding. Therefore, the adjustable backrest not only enhances convenience and comfort but also broadens the range of people who can use electric tricycles.

[0003] Document CN217969765U discloses an electric tricycle with an adjustable backrest, including an electric tricycle body and a power supply box. The power supply box is mounted on the surface of the electric tricycle body, a mounting bracket is mounted on the surface of the power supply box, a seat cushion is mounted on the surface of the mounting bracket, and a fixing plate is also mounted on the surface of the power supply box. A backrest is provided on the inner wall of the fixing plate, and a backrest cushion is connected to one side of the backrest. Drive gears are connected to the bottom two sides of the backrest. This invention removes the positioning pin from the surface of the positioning block, then rotates the backrest inside the recess of the fixing plate, driving the drive gears on both sides of the backrest to rotate until the backrest is rotated to a certain angle. The positioning pin then passes through the positioning block and engages with the fixing plate, fixing the backrest after rotation. This allows the rider to easily adjust the backrest to a suitable angle for comfortable long-distance riding.

[0004] However, in practical applications, although the comparison document provides the function of adjusting the lateral angle of the backrest, it lacks the ability to adjust the longitudinal height. This limitation means that users of different heights cannot adjust to the most suitable driving posture according to their individual needs, thus affecting driving comfort. Utility Model Content

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides an electric tricycle with an adjustable backrest, comprising:

[0027] The main body of the electric tricycle is 100.

[0028] The adjustment mechanism 200 includes a transverse component 201 disposed on one side of the electric tricycle body 100, a longitudinal component 202 disposed on one side of the transverse component 201, and a locking component 203 disposed inside the transverse component 201 and the longitudinal component 202.

[0029] Specifically, the electric tricycle body 100 also includes a charging component 101, which is disposed in the inner cavity of the electric tricycle body 100.

[0030] It should be noted that the charging component 101 is located inside the body 100 of the electric tricycle, which not only makes it convenient for users to charge the vehicle at any time, but also ensures the safety and stability of the charging process through its built-in safety protection mechanisms, such as overcharge protection and short circuit protection. In addition, the charging interface design conforms to international standards and supports multiple charging methods, which improves the convenience of use.

[0031] Specifically, the transverse component 201 includes a fixing plate 2011 fixedly installed on the outer surface of the electric tricycle body 100, a guide rail 2012 fixedly installed on the outer surface of the fixing plate 2011, and a slider 2013 slidably connected to the outer surface of the guide rail 2012.

[0032] It should be noted that the solid connection between the fixed plate 2011 and the guide rail 2012 ensures the smooth sliding of the slider 2013 on the guide rail. This design not only improves the durability and reliability of the adjustment mechanism 200, but also allows for precise adjustment of the position according to actual needs, enhancing the operational flexibility and adaptability of the equipment.

[0033] Specifically, the longitudinal component 202 includes a slide plate 2021 fixedly mounted on the outer surface of the slider 2013, an adjusting block 2022 fixedly mounted on the outer surface of the slide plate 2021, and a locking block 2023 fixedly mounted on the outer surface of the adjusting block 2022.

[0034] It should be noted that the adjustment block 2022 installed on the skateboard 2021 can be finely adjusted along the skateboard, while the locking block 2023 provides additional safety to prevent accidental movement. This structural design enables the longitudinal component 202 to provide stable support in different working environments and meet diverse operational needs.

[0035] Specifically, the locking component 203 includes a locking groove 2031 formed on the outer surface of the guide rail 2012, which is used to lock the slider 2013.

[0036] It should be noted that the locking groove 2031 is formed on the outer surface of the guide rail 2012. When the slider 2013 reaches the predetermined position, it can be firmly locked by the locking device to avoid position displacement caused by external vibration or operation error, thus ensuring the stability and safety of the adjustment mechanism 200.

[0037] Specifically, the locking component 203 also includes a slot 2032 formed on the outer surface of the skateboard 2021, which is used to cooperate with the adjustment block 2022.

[0038] It should be noted that the slot 2032 is located on the outer surface of the slide plate 2021 and is specially designed to be used in conjunction with the adjustment block 2022. This design allows for quick and stable locking during longitudinal adjustment, ensuring adjustment accuracy while simplifying the operation process and improving work efficiency.

[0039] When using the electric tricycle, first ensure that the charging component 101 of the main body 100 is correctly connected and fully charged to provide sufficient power support for the adjustment mechanism 200. When the position of the device needs to be adjusted, activate the lateral component 201, and the slider 2013 moves smoothly along the guide rail 2012 on the fixed plate 2011 to reach the desired lateral position. After reaching the designated position, use the locking groove 2031 in the locking component 203 to firmly lock the slider 2013 to ensure its stability. Next, operate the longitudinal component 202, and move the adjusting block 2022 on the slide plate 2021 to achieve precise longitudinal adjustment. The locking block 2023 and the slot 2032 cooperate to lock the longitudinal position to ensure its stability. Throughout the process, the user can flexibly adjust the lateral and longitudinal positions according to actual needs, while relying on the locking component 203 to ensure the stability after each adjustment, thereby meeting the operational requirements of different application scenarios and improving work efficiency and ease of use.

[0040] In summary, through the coordination of 200 components of the adjustment mechanism, users can finely adjust the position of the backrest according to their individual needs. Whether it is to find the most comfortable sitting posture or to adapt to different road conditions, it can be easily achieved, improving the user's riding comfort and usage flexibility.
