Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, specifically to an electric tricycle carriage with a multi-functional support structure. Background Technology

[0002] In the design of electric tricycles, the transition area between the seat and the rear cargo bed typically features a crossbeam structure with a backrest fixed to it. This backrest not only provides crucial support for the driver to alleviate fatigue during long journeys, but also offers reliable support when passengers are in the cargo bed. It cleverly connects the driving and riding spaces, playing an indispensable role in ensuring both passenger comfort and safety.

[0003] However, most electric tricycle backrests on the market currently use a fixed installation design. While this structure is stable, it has the drawback of limited functionality. Because it is fixed and not adjustable, the backrest can only meet basic leaning needs and cannot be expanded to meet different riding scenarios, which limits its application scenarios. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide an electric tricycle carriage with a multi-functional support structure, so as to solve the problem that the backrest has a single function and cannot be expanded in the existing technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an electric tricycle carriage with a multi-functional support structure, including: a crossbeam fixed on the frame, a cargo box and a seat with a handrail respectively provided on both sides of the crossbeam, and a backrest plate for use with the crossbeam; wherein, the backrest plate includes a plate body and an insert shaft provided in the plate body, and the handrail, crossbeam and cargo box are respectively provided with a first fixing hole, a second fixing hole and a third axle seat for use with the insert shaft.

[0006] Optionally, the truck bed and seat are both fixed to the frame, the handrails are fixed to both sides of the seat, and the handrails are also fixed to the frame.

[0007] Optionally, a first axle seat near the vehicle seat and a second axle seat near the vehicle bed are respectively fixed on the crossbeam, and a first rotating shaft for use with the first axle seat and a second rotating shaft for use with the second axle seat are respectively fixed on the plate.

[0008] Optionally, when the insert shaft is inserted into the first fixing hole, the first rotating shaft is rotatably disposed in the first bearing seat, and the second rotating shaft does not contact the second bearing seat.

[0009] Optionally, when the insert shaft is inserted into the second fixing hole, the first rotating shaft and the second rotating shaft are respectively rotatably disposed in the first bearing seat and the second bearing seat.

[0010] Optionally, when the insert shaft is disposed within the third bearing seat, the second rotating shaft is rotatably disposed within the second bearing seat, and the first rotating shaft does not contact the first bearing seat.

[0011] Optionally, the plate body is provided with a telescopic structure for driving the insertion shaft to extend and retract.

[0012] Optionally, the telescopic structure includes a first rotating plate rotatably disposed within the plate body, a second rotating plate rotatably connected to both ends of the first rotating plate, a shaft rotatably disposed on the second rotating plate, a fixing block located within the plate body sleeved outside the shaft, and a spring sleeved outside the shaft, with both ends of the spring abutting against the fixing block and the shaft.

[0013] Optionally, a screwing part is also fixed on the first rotating plate, and the screwing part is rotatably connected to the plate body.

[0014] Optionally, the exterior of the plate is coated with a sun-resistant coating.

[0015] The beneficial effects of this utility model are as follows:

[0016] The backrest of this utility model has a plate body and an insert shaft disposed on the plate body. The plate body also has a first rotating shaft and a second rotating shaft.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As mentioned earlier, most electric tricycle backrests on the market currently use a fixed installation design. While this structure is stable, it suffers from the drawback of limited functionality. Because it is fixed and not adjustable, the backrest can only meet basic leaning needs and cannot be expanded to suit different riding scenarios, thus limiting its application.

[0033] To address this issue, this utility model provides an electric tricycle carriage with a multi-functional support structure. This carriage features a retractable backrest, allowing it to provide different functions according to varying usage needs, thus solving the aforementioned problems. This utility model achieves its solution in the following way.

[0034] Example 1:

[0035] Please refer to the instruction manual appendix. Figures 1 to 7 As shown in the figure, Embodiment 1 provides an electric tricycle carriage with a multi-functional support structure. The electric tricycle carriage includes a frame 1, a cargo box 2, a handlebar 3, a seat 4, a crossbeam 5, and a backrest 6. The seat 4, crossbeam 5, and cargo box 2 are fixed to the frame 1 from front to back. The crossbeam 5, serving as a transition between the cargo box 2 and the seat 4, has a connecting solid plate structure and an inverted U-shaped frame structure. Two seats 4 are provided, symmetrically fixed to both sides of the seat 4, and the seats 4 are also fixed to the frame 1. The backrest 6 is located within the frame structure of the crossbeam 5, and the backrest 6 can rotate and change shape within it, thus providing different functions.

[0036] like Figure 1 or Figure 2 As shown, in this embodiment, the backrest 6 includes a plate 61 and an insert shaft 63 disposed within the plate 61. The insert shaft 63 extends out of the plate 61 in its normal state and retracts into the plate 61 via a telescopic mechanism when needed. Meanwhile, a first rotating shaft 611 and a second rotating shaft 612 are fixed to the bottom of the plate 61 (the portion of the plate structure near the crossbeam 5). The first rotating shaft 611 is located on the side of the plate 61 closest to the seat 4, and the second rotating shaft 612 is located on the side of the plate 61 closest to the cargo bed 2 (e.g.,...). Figure 3(As shown). Correspondingly, on the top end face of the 5 plate structure of the crossbeam, a first bearing 51 and a second bearing 52 are respectively fixed for use with the first rotating shaft 611 and the second rotating shaft 612.

[0037] Meanwhile, a first fixing hole 31 is correspondingly provided on the handrail 3 (the side where the two handrails 3 are close to each other). A second fixing hole 53 is correspondingly provided on the inner side wall of the crossbeam 5, and a third axle seat 21 is correspondingly fixed on the top end face of both sides of the truck bed 2 (e.g., Figure 5 As shown in the diagram. The first fixing hole 31, the second fixing hole 53, and the third shaft seat 21 are all used in conjunction with the insert shaft 63. When the insert shaft 63 is positioned on the first fixing hole 31, the second fixing hole 53, and the third shaft seat 21 respectively, the back plate 6 rotates in different shapes, thereby performing different functions.

[0038] Example 2:

[0039] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. In this embodiment two, the backrest 6 presents as follows: Figure 1 In the configuration shown, the insert shaft 63 is housed within the third axle seat 21, and the second rotating shaft 612 is rotatably mounted (or directly placed) within the second axle seat 52. At this time, the first rotating shaft 611 is suspended and does not contact the first axle seat 51. In this configuration, most of the area of ​​the plate 61 is located within the cargo bed 2, serving as a seat. If a passenger is in the cargo bed 2, the passenger can sit on it and lean against the crossbeam 5. This eliminates the risk of the passenger falling off the tricycle by eliminating the need to sit on the side of the cargo bed 2.

[0040] Example 3:

[0041] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment three. In this embodiment three, the backrest 6 is presented as follows: Figure 5 In the configuration shown, the insert shaft 63 is inserted into the interior of the second fixing hole 53, and the second rotating shaft 612 and the first rotating shaft 611 are respectively rotatably disposed (or directly placed) inside the second axle seat 52 and the first axle seat 51. In this configuration, the plate 61 fills the inverted U-shaped frame structure of the crossbeam 5, and its entirety is perpendicular to the seat 4. It functions as a backrest, allowing the driver to lean against it when seated on the seat 4, thus providing driving comfort.

[0042] Example 4:

[0043] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment four. In this embodiment four, the backrest 6 presents as follows: Figure 6 and Figure 7 In the configuration shown, the insert shaft 63 is inserted into the first fixing hole 31. At this time, the first rotating shaft 611 is rotatably positioned (or directly placed) inside the first axle seat 51, while the second rotating shaft 612 is suspended and does not contact the second axle seat 52. In this configuration, the plate 61 and the seat area of ​​the seat 4 overlap. Because the exterior of the plate 61 is coated with a sun-resistant coating (e.g., a nano-zinc oxide coating or a silane-modified sun-resistant coating), the plate 61 possesses a certain degree of sun protection.

[0044] Therefore, when the electric tricycle is not in use, the backrest 6 can be switched to the above-mentioned position, thus preventing the seat 4 from aging due to sun exposure. Since the seat 4 is mostly made of black leather, it absorbs sunlight and generates heat. Therefore, covering it with the backrest 6 prevents it from directly facing the sun, thus preventing it from getting too hot. Users can simply flip up the backrest 6 to start the vehicle, avoiding the problem of the seat 4 being too hot to sit on. At the same time, the backrest 6 covering the seat 4 also prevents rainwater from wetting the seat 4, eliminating the hassle of users having to wipe the seat 4 dry before driving in the rain.

[0045] Example 5:

[0046] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Five. In this Embodiment Five, as... Figure 3 or Figure 4 As shown, before the backing plate 6 can be changed to any of the aforementioned configurations, the position of the insert shaft 63 needs to be adjusted via a telescopic mechanism. The telescopic mechanism is located inside the plate body 61. It includes a first rotating plate 64 rotatably mounted (e.g., connected via bearings) within the plate body 61. A second rotating plate 65 is rotatably connected to both ends of the first rotating plate 64. The insert shaft 63 is rotatably mounted on the second rotating plate 65. A fixing block 66 located within the plate body 61 is also sleeved around the insert shaft 63. A spring 67 is also sleeved around the insert shaft 63, with both ends abutting against the fixing block 66 and the insert shaft 63 (note that the spring 67 does not contact the second rotating plate 65). A screwing part 62 is also fixed to the first rotating plate 64, and the screwing part 62 is rotatably connected to the plate body 61.

[0047] Therefore, when the telescopic mechanism is not under force, the spring 67 is in a contracted state. At this time, the rotational connection point of the insertion shaft 63 and the second rotating plate 65 is pulled by the spring 67, and the insertion shaft 63 extends out of the plate body 61, thereby performing any of the operations in the aforementioned embodiments. When it is necessary to change the state of the backrest 6, the user only needs to turn the screw part 62. The screw part 62 will drive the first rotating plate 64 to rotate, thereby driving the second rotating plate 65 to move, thus pulling the insertion shaft 63 until it is completely inserted into the plate body 61. This adjusts the state of the backrest 6. At this time, the spring 67 is stretched, thereby generating a deformation force. When adjusted to the specified state, the user uses their hand, and under the action of the deformation force, the spring 67 drives the insertion shaft 63 to reset, re-extend out of the plate body 61, and finally complete the fixation.

[0048] Of course, even without spring 67, the above operation can still be completed by the user simply by turning the screw 62.

[0049] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to:

[0050] The backrest 6 of this utility model has a plate body 61 and an insert shaft 63 disposed on the plate body 61. The plate body 61 also has a first rotating shaft 611 and a second rotating shaft 612. Meanwhile, the seat 4, crossbeam 5, and truck bed 2 are respectively provided with a first fixing hole 31, a second fixing hole 53, and a third axle seat 21 for use with the insert shaft 63. This makes:

[0051] When the electric tricycle is not driven, the insert shaft 63 is located in the first fixing hole 31. At this time, the first rotating shaft 611 is rotatably set in the first axle seat 51, the second rotating shaft 612 is suspended, and the plate 61 covers the surface of the seat 4, thereby serving as sun protection and rain protection, and forming protection for the seat 4.

[0052] When the electric tricycle is being driven, the insert shaft 63 is located in the second fixing hole 53. At this time, the first rotating shaft 611 and the second rotating shaft 612 are respectively rotatably set in the first axle seat 51 and the second axle seat 52. The plate 61 is located in the crossbeam 5, thus acting as a backrest to provide the driver with support and rest.

[0053] Meanwhile, if the electric tricycle needs to carry passengers during driving, the backrest 6 can be flipped down, so that the insert shaft 63 is set in the third axle seat 21. At this time, the second rotating shaft 612 is rotated and set in the second axle seat 52, and the first rotating shaft 611 is suspended, thus serving as a seat, so that the passengers in the truck bed 2 do not need to sit on the side of the truck bed 2, avoiding the risk of them falling off.

[0054] In summary, the electric tricycle carriage with a multi-functional support structure designed in this utility model can change the shape of the backrest 6 according to actual usage needs to give it more functions, thereby enriching its application scenarios.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
