Description

Technical Field

[0001] This utility model relates to the field of tricycle technology, specifically to a quick-switching electric tricycle for both passenger and cargo use. Background Technology

[0002] Electric tricycles, with their advantages of practicality, aesthetics, maneuverability, simple maintenance, convenient repair, and low price, can easily navigate narrow roads and are very convenient to drive and park. Therefore, they are widely used in short-distance transportation fields such as households, urban and rural areas, individual rentals, factories, mines, sanitation, and community cleaning. Currently, existing electric tricycles are usually single-purpose passenger or cargo vehicles. If both passenger and cargo functions are required, the switching process requires tools to disassemble / install components, which is inefficient. Moreover, after switching, problems such as center of gravity shift and single structural function (such as the frame only serving as a load-bearing element) are prone to occur, affecting the convenience of use and driving stability. Utility Model Content

[0003] This utility model aims to solve the above-mentioned technical problems by providing a quick-switching electric tricycle for both passenger and cargo use.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0005] A quick-switching electric tricycle for both passenger and cargo use includes a main body, on which a front seat is fixedly connected;

[0006] A middle seat is slidably mounted on one side of the front seat and can be inserted into the front seat;

[0007] A seat cushion is installed at the upper end of the middle seat;

[0008] Both sides of the middle seat are equipped with hinges that can drive the middle seat cushion to rotate and move.

[0009] Preferably, the front seat has a cavity on the side near the middle seat that mates with the middle seat.

[0010] Preferably, a slide rail is mounted on the main body, and a slider for use with the slide rail is mounted on the lower end of the middle seat.

[0011] Preferably, the hinge includes a first hinge arm, a second hinge arm, a third hinge arm, and a fourth hinge arm; one end of the first hinge arm and the second hinge arm are coaxially hinged to the side of the center seat, and the other ends of the first hinge arm and the second hinge arm are respectively hinged to the third hinge arm and the fourth hinge arm, the middle of the third hinge arm and the fourth hinge arm are hinged, and the other ends of the third hinge arm and the fourth hinge arm are fixedly connected to the center seat cushion.

[0012] Preferably, the fourth hinge arm has a threaded hole, and a fixing bolt for fixing is threaded into the threaded hole.

[0013] Preferably, a rear seat and a guardrail are installed at the rear end of the main vehicle body.

[0014] Preferably, a roof is installed on the main vehicle body.

[0015] With the above structure, this utility model has the following advantages:

[0016] This utility model achieves dual modes of use—passenger mode and cargo mode—by moving the slide rail and the middle seat of the slider, and by installing the middle seat through a hinge. It can be used for both passenger and cargo transport, is simple to operate and convenient to use, and solves the defects of existing electric tricycles such as low efficiency in switching between passenger and cargo transport, single structural function, and unstable center of gravity.

[0021] The present invention will now be described in further detail in conjunction with the full text.

[0022] Combined with appendix Figures 1-3 A quick-switching electric tricycle for both passenger and cargo use includes a main body 1, on which a front seat 2 is fixedly connected;

[0023] A middle seat 3 is slidably installed on one side of the front seat 2 and the middle seat 3 can enter the front seat 2;

[0024] A middle seat cushion 5 is installed on the upper end of the middle seat 3;

[0025] Both sides of the middle seat 3 are equipped with hinges 4 that can drive the middle seat pad 5 to rotate and move.

[0026] The front seat 2 has a cavity on the side near the middle seat 3 that allows the middle seat 3 to enter.

[0027] In practical use, this utility model, such as Figure 3As shown, a slide rail 6 is mounted on the main body 1, and a slider for use with the slide rail 6 is mounted on the lower end of the middle seat 3. Hinges 4, which can rotate and move the middle seat cushion 5, are mounted on both sides of the middle seat 3. Each hinge 4 includes a first hinge arm 401, a second hinge arm 402, a third hinge arm 403, and a fourth hinge arm 404. One end of the first hinge arm 401 and the second hinge arm 402 are coaxially hinged to the side of the middle seat 3. The other end of 402 is hinged to the third hinge arm 403 and the fourth hinge arm 404 respectively. The third hinge arm 403 and the fourth hinge arm 404 are hinged in the middle. The other end of the third hinge arm 403 and the fourth hinge arm 404 is fixedly connected to the middle seat pad 5. Pulling the hinge 4 causes the middle seat pad 5 to rotate to the side of the middle seat 3 away from the front seat 2. The fixing bolt 10 is installed in the threaded hole to abut against the middle seat 3 to achieve the limiting function. Then, the middle seat 3 is driven into the front seat 2 through the slide rail 6 and the slider.

[0028] Specifically, the slider is equipped with locking components for locking and fixing the middle seat 3, such as screws or positioning pins, which are existing technologies and will not be described in detail here.

[0029] In a specific implementation of this utility model, the fourth hinge arm 404 is provided with a threaded hole, and a fixing bolt 10 for fixing is threaded into the threaded hole. The fixing bolt 10 installed in the threaded hole can abut against the middle seat 3 to achieve a limiting function.

[0030] Specifically, the rear end of the main vehicle body 1 is equipped with a rear seat 7 and a guardrail 8, and a roof 9 is installed on the main vehicle body 1. The frame assembly adopts a "main load-bearing tube + modular installation area" design. The top horizontal tubes simultaneously realize the functional reuse of "passenger handrails" and "cargo guardrails", reducing additional structural components.

[0031] The working principle of this utility model:

[0032] In passenger mode, the middle seat is adjusted to a suitable position via the bottom slide rail and slide rail slot. The middle seat is then fixed to the seat via the hinge and hinge slot, ready for passenger use.

[0033] In cargo mode, the middle seat cushion is extended to the appropriate height via the hinge, and then rotated to the rear of the middle seat via the hinge and the middle seat fixing bolt. At this time, the middle seat assembly is pushed into the front seat via the bottom slide rail and slide rail slot, and then it can be used for cargo loading.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
