Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, and in particular to a trailer structure and an electric tricycle. Background Technology

[0002] Electric tricycles are three-wheeled transport vehicles powered by batteries and driven by motors, used for carrying goods or people. They have advantages such as strong applicability, maneuverability, convenient maintenance, and low price, and are widely used in short-distance transportation.

[0003] To improve passenger comfort when the vehicle is carrying passengers, many vehicles are equipped with folding seats. For example, the existing utility model patent with publication number CN204605588U discloses a detachable folding seat structure for an electric tricycle, including a gantry frame, a clamp, a rotating shaft, a rotating support plate, and a seat cushion. The seat cushion can be flipped over via the rotating shaft. When laid flat, it can carry passengers, and when erected, it fits against the gantry frame of the vehicle.

[0004] Regarding the aforementioned prior art, the inventor believes that the existing folding seat cushions for train carriages have a fixed seat position, and in order to flip vertically and fit against the door frame, the inner side of the seat cushion is close to the backrest formed by the door frame, which makes the actual effective width of the seat cushion for sitting small and the riding comfort poor. Utility Model Content

The track beams are fixed to the top wall of the corresponding eaves board. Track grooves are opened on the side wall of the track beams near the seat cushion frame. The length direction of the track grooves is set perpendicular to the direction of the door frame.

[0009] A connecting shaft is inserted into the track groove. The connecting shaft is fixedly connected to the seat frame. The connecting shaft is rotatably connected to the track beam and can slide along the track groove. When the seat frame is set vertically, it is fixed to the door frame by a latch.

[0010] Furthermore, the track slot includes a front folded hole, a sliding straight hole, and a rear folded hole that are interconnected. The front folded hole and the rear folded hole are respectively connected to the two ends of the sliding straight hole, and the connection between the front folded hole and the sliding straight hole and the connection between the rear folded hole and the sliding straight hole are both corner structures.

[0011] Furthermore, there are two gantry frames, which are respectively located on the top of the front panel and the top of the rear door, and sliding flip-up cushions are installed on both gantry frames.

[0012] Furthermore, a folding table is provided inside the main body of the carriage. The folding table includes a tabletop and four table legs hinged to the bottom corner of the tabletop. The four table legs are staggered in the flipping direction.

[0013] Furthermore, a limiting sleeve is provided on the side panel at the position corresponding to the table leg, and each table leg is inserted into the limiting sleeve.

[0014] This utility model also provides an electric tricycle, including the aforementioned trailer structure, with a connecting frame fixed at the front end of the trailer structure, and the electric tricycle is hinged to the connecting frame via a rotating shaft.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a trailer car structure.

[0026] Reference Figures 1 to 4 A trailer structure includes a trailer body 1 formed by connecting a floor plate 11, a front plate 12, a rear door 13 and two side plates 14, and a gantry 15 mounted on the trailer body 1. A horizontally arranged eaves plate 141 is fixed to the top of each side plate 14, and a sliding flip-up seat cushion 162 is mounted on the gantry 15. The sliding flip-up seat cushion 162 includes a seat frame 161, a seat cushion 162, a track beam 163, and a latch 164. The seat cushion 162 is fixed to the seat frame 161. There are two track beams 163, which are located at both ends of the seat frame 161. The track beams 163 are fixed to the top wall of the corresponding eaves 141. A track groove is opened on the side wall of the track beam near the seat frame 161. The track groove extends in a direction perpendicular to the gantry 15. A connecting shaft 165 passes through the track groove. The connecting shaft 165 is fixedly connected to the seat frame 161 and rotatably connected to the track beam 163 and can slide along the track groove. When the seat frame 161 is set vertically, it is fixed to the gantry 15 by the latch 164.

[0027] When passengers are needed, the latch 164 is opened, the seat cushion 162 is flipped down and flattened, and its position can be adjusted forward for passengers to sit on. Compared with the existing flip seat cushion 162, the seat cushion 162 has a wider effective seating space and better comfort for people of different body types because its front and back positions can be adjusted within a certain range. When passengers are not needed, the seat cushion 162 can be moved closer to the mast 15, then flipped up to make it flush with the mast 15, and finally locked in place with the latch 164. It is easy to operate and can meet different needs for carrying goods or people.

[0028] Reference Figure 5The track slot includes a front folded hole 166, a sliding straight hole 167, and a rear folded hole 168 that are interconnected. The front folded hole 166 and the rear folded hole 168 are respectively connected to the two ends of the sliding straight hole 167. The connection between the front folded hole 166 and the sliding straight hole 167, and the connection between the rear folded hole 168 and the sliding straight hole 167 are both corner structures. The corner structure between the front folded hole 166 and the sliding straight hole 167 faces downward. The corner structure between the rear folded hole 168 and the sliding straight hole 167 is T-shaped. The specific structural design of the track groove allows the connecting shaft 165 to slide within the sliding straight hole 167 when adjusting the front and rear positions of the seat cushion 162. The front folding hole 166 and the rear folding hole 168 serve as the extreme positions of the front and rear of the seat cushion 162. By forming a corner structure with the sliding straight hole 167, they achieve a positioning effect, limiting the front and rear displacement of the seat cushion 162 at the two extreme positions. This ensures the stability of the seat cushion 162, prevents wobbling, and improves riding comfort. When it is necessary to vertically flip the seat cushion 162, the seat cushion 162 needs to be slightly lifted upwards so that the connecting shaft 165 disengages from the front folding hole 166, allowing the seat cushion 162 to be moved closer to the gantry 15. Similarly, the seat cushion 162 needs to be slightly lifted upwards so that the connecting shaft 165 disengages from the rear folding hole 168 before the seat cushion 162 can slide.

[0029] Reference Figure 2 There are two masts 15, which are respectively located on the top of the front panel 12 and the top of the rear door 13. Each mast 15 is equipped with a sliding flip-up seat cushion 162. This configuration can further increase the number of passengers.

[0030] Reference Figure 2 and Figure 6 The main body 1 of the trailer is equipped with a folding table 17, which includes a tabletop 171 and four table legs 172 hinged to the bottom corners of the tabletop 171. The four table legs 172 are staggered in the direction of flipping. The folding table 17 inside the main body 1 of the trailer can be used for placing items and dining, making the trailer structure more functional and practical. In addition, when not in use, the folding table 17 can be folded under the tabletop 171, reducing its occupation of interior space.

[0031] Limiting sleeves 142 are provided on the side panel 14 at positions corresponding to the table legs 172, and each table leg 172 is inserted into the limiting sleeve 142. The design of the limiting sleeve 142 can effectively restrict and fix the folding table 17, ensuring the stability of the folding table 17 during travel.

[0032] This utility model also discloses an electric tricycle, including the aforementioned trailer structure. A connecting frame 2 is fixed to the front end of the trailer structure, and the electric tricycle is hinged to the connecting frame 2 via a pivot. The electric tricycle provides power to the trailer structure, and this structural design effectively increases the number of goods or passengers the electric tricycle can carry, making it more practical.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
