DETAILED DESCRIPTION

[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0021] The electric tricycle seat according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the electric tricycle seat of the embodiment of the present utility model may include a support seat 10, a seat frame 20, two limiting mechanisms 30 and two driving mechanisms 40.

[0023] The top surface of the support base 10 defines two symmetrically distributed countersunk holes 11. The seat frame 20 is rotatably mounted on the support base 10. The side walls of the seat frame 20 define a longitudinal mounting chamber 21 and a transverse mounting chamber 22, respectively. The longitudinal mounting chamber 21 communicates with the transverse mounting chamber 22. It should be noted that the support base 10 described in this embodiment can be secured to a tricycle frame (not shown) using threaded fasteners (screws, bolts, or bolts).

[0024] In this example of the present invention, the two longitudinal installation chambers 21 are respectively located in the two side walls of the backrest of the seat frame 20 , and the two transverse installation chambers 22 are respectively located in the two armrest walls of the seat frame 20 .

[0025] The two limiting mechanisms 30 are respectively disposed in the corresponding longitudinal installation chambers 21 for vertical movement, and the bottom ends of the limiting mechanisms 30 pass through the longitudinal installation chambers 21 and extend into the countersunk hole 11 .

[0026] The two driving mechanisms 40 are respectively movably disposed in the corresponding transverse installation chambers 22 , and the two driving mechanisms 40 are respectively connected to the corresponding limiting mechanisms 30 in a conflicting manner.

[0027] In order to clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 2 As shown, the limiting mechanism 30 may include a guide rod 31 , a slider 32 , a baffle 33 and a spring 34 .

[0028] Among them, the guide rod 31 is arranged in the longitudinal installation chamber 21 for lifting and movement, and the bottom end of the guide rod 31 passes through the longitudinal installation chamber 21 and extends into the countersunk hole 11. A through hole 301 is opened on the guide rod 31 and near the top of the guide rod 31, wherein the top surface of the through hole 301 is a slope.

[0029] The slider 32 is arranged at the bottom end of the guide rod 31, and two symmetrically distributed arc slides 12 are opened on the top surface of the support seat 10, and the two arc slides 12 are respectively connected to the corresponding countersunk holes 11, wherein the slider 32 is slidably connected to the arc slide 12 when the seat frame 20 rotates.

[0030] The baffle 33 is slidably disposed in the longitudinal installation chamber 21 and is fixedly connected to the guide rod 31. A spring 34 is sleeved on the guide rod 31, and one end of the spring 34 is fixedly connected to the baffle 33, and the other end of the spring 34 is fixedly connected to the top wall of the longitudinal installation chamber 21.

[0031] Furthermore, in one embodiment of the present invention, Figure 2 As shown, the driving mechanism 40 may include a driving block 41 , a driving rod 42 and a pressing head 43 .

[0032] The driving block 41 is movably disposed in the transverse mounting chamber 22 , and one end of the driving block 41 has a slope that contacts and connects with the inclined surface of the through hole 301 .

[0033] One end of the driving rod 42 is fixedly connected to the other end of the driving block 41 , and the other end of the driving rod 42 passes through the transverse mounting chamber 22 and is fixedly connected to the pressing head 43 .

[0034] It is understandable that when the passenger needs to get off the vehicle, the passenger can drive the seat frame 20 to rotate according to the desired getting off position.

[0035] Specifically, the passenger drives the driving block 41 to move towards the backrest direction of the seat frame 20 by pressing the pressing head 43 in one of the driving mechanisms 40 to drive the driving rod 42, the moving driving block 41 drives the corresponding guide rod 31 to move upwards, the upward moving guide rod 31 drives the sliding block 32 and the baffle 33 to move upwards synchronously, and the upward moving baffle 33 compresses the spring 34.

[0036] When the bottom surface of the sliding block 32 moves to the same plane as the bottom surface of the arc-shaped slide 12, the passenger can manually rotate the seat frame 20, at this time, the seat frame 20 takes the guide rod 31 in the other limiting mechanism 30 as the rotation shaft, and makes the sliding block 32 slide along the arc-shaped slide 12, thereby realizing the rotation of the seat frame 20.

[0037] When it is necessary to reset the seat frame 20, the passenger rotates the seat frame 20 and makes the sliding block 32 in the arc-shaped slide 12 slide above the counterbore 11, at this time, the baffle 33 moves downwards under the tension of the spring 34, the downward moving baffle 33 drives the sliding block 32 to move downwards through the guide rod 31 and slide into the counterbore 11, so as to limit the seat frame 20. In turn, the rotating seat of the electric tricycle is no longer limited to single direction rotation, greatly improving the flexibility of the seat, so that the passenger can choose the most suitable direction of getting on and off the vehicle according to the actual situation, effectively avoiding the inconvenience caused by blocked passage.

[0038] In another embodiment of the present application, as shown in Figure 2 and Figure 3 The electric tricycle seat can further include two magnet blocks 50, wherein the top surface edge of the support seat 10 is symmetrically provided with two notches 13, and the two magnet blocks 50 are respectively adsorbed in the corresponding notches 13 and are respectively fixedly connected with the bottom wall of the seat frame 20, wherein the magnet block 50 and the notch 13 can be semicylindrical. In this way, the magnet block 50 can be rotated out of or into the notch 13 when the seat frame 20 rotates.

[0039] It should be noted that the support seat 10 described in this embodiment can be made of a material that can be adsorbed by a magnet, for example, iron material. In addition, a magnet that can be adsorbed with the magnet block 50 can also be fixedly arranged on the inner wall of the notch 13.

[0040] It can be understood that by fixedly arranging the magnet block 50 on the bottom wall of the seat frame 20, the seat frame 20 can be adsorbed and fixed on the support seat 10 through the magnet block 50, which can effectively increase the stability of the seat frame 20 and avoid shaking when the passenger sits on the seat frame 20.

[0041] In summary, the electric tricycle seat of the embodiment of the utility model can make the rotating seat of the electric tricycle no longer limited to rotation in a single direction, greatly improving the flexibility of the seat, allowing passengers to choose the most appropriate direction of getting on and off the vehicle according to actual conditions, and effectively avoiding the inconvenience caused by blocked passages.
