Description

Technical Field

[0001] This utility model relates to the field of electric tricycle covered vehicle frame technology, and in particular to a split-type frame specifically for electric recreational tricycle covered vehicles. Background Technology

[0002] Electric recreational tricycles with canopies are a type of short-distance transportation tool that has emerged in recent years. They are light vehicles that combine electric drive, a three-wheeled structure, and a canopy design. Powered by electricity, they produce no exhaust emissions, meet the requirements of green travel, are easy to operate, and are suitable for the elderly and users unfamiliar with motor vehicle operation. They are more comfortable than ordinary electric tricycles, provide shelter from wind and rain, and can flexibly navigate through residential areas, alleys, and rural roads. They are widely used in urban short-distance travel, leisure and entertainment, scenic area transportation, elderly transportation, and urban-rural connections.

[0003] Currently, the frames of electric tricycles with canopies are unibody structures. While this unibody frame structure improves overall strength in the manufacturing process, it also brings several negative impacts, specifically: First, the unibody frame is bulky and complex, requiring more irregular curved surfaces and dead corners to be covered during painting. To achieve a uniform paint finish, an electrophoretic painting process is needed, which requires a dust-free, temperature-controlled environment and multiple rotations of the frame to cover all areas. The unibody frame not only prolongs the painting time per session but also significantly increases energy consumption and equipment investment costs. Second, the unibody frame cannot be disassembled for transport. During transportation, the unibody frame occupies a large space and requires dedicated support brackets, resulting in low space utilization. Furthermore, unassembled frames require large areas of flat ground for storage, leading to a surge in warehousing costs. In addition, if any part of the unibody frame is damaged by collision, deformation, or corrosion during manufacturing or use, the entire frame must be scrapped because it cannot be replaced locally, making subsequent repairs and maintenance extremely difficult. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a split frame for electric recreational tricycles.

[0005] This utility model is achieved through the following technical solution:

[0006] A split-type frame for an electric recreational tricycle includes a frame body, a door frame, a seat bucket frame, and a rear frame that are detachably connected to the frame body. Two sets of frame bodies are arranged opposite each other. The door frames are detachably connected to the two frame bodies respectively. The seat bucket frame and the rear frame are detachably connected between the rear sides of the two frame bodies respectively, and the rear frame is located above the seat bucket frame.

[0007] According to the above technical solution, preferably, a first connecting ear is fixedly connected to the lower rear side of the frame body, and a second connecting ear is provided on both sides of the seat bucket frame. When the seat bucket frame is assembled between the rear sides of the two frame bodies, the first connecting ear and the second connecting ear are mated and fixedly connected by bolts.

[0008] According to the above technical solution, preferably, a third connecting ear is fixedly connected to the upper rear side of the frame body, and a fourth connecting ear is provided on both sides of the rear frame. When the rear frame is assembled between the rear sides of the two frame bodies, the third connecting ear and the fourth connecting ear are mated and fixedly connected by bolts.

[0009] According to the above technical solution, preferably, one side of the door frame is hinged to the vehicle frame body, wherein a hinge mounting area is provided on one side of the door frame, and when the door frame is assembled into the vehicle frame body, the door frame is hinged to the vehicle frame body in the hinge mounting area via hinges.

[0010] The beneficial effects of this utility model are:

[0011] This invention features a modular, split-type frame design for the electric recreational tricycle, connecting core load-bearing components with bolts to balance strength and detachability. In terms of manufacturing, segmented welding and independent pre-assembly enhance assembly flexibility, allowing for compatibility with automated production lines and effectively shortening assembly line time. The split, independent frame structure also reduces component size, enabling parallel electrophoretic painting and avoiding the dead zones and missed areas of a one-piece frame, improving paint uniformity and reducing rework rates. During storage and transportation, the split structure allows for nested stacking, significantly improving space utilization and increasing the load capacity of the transport equipment. Furthermore, vulnerable parts such as door frames can be individually packaged, reducing transport damage rates. In addition, in the event of collision damage, only a portion of the frame needs to be replaced, allowing for targeted repair of individual parts and reducing maintenance and return costs.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] As shown in the figure, this utility model includes a frame body 1, a door frame 5, a seat bucket frame 3, and a rear frame 2 that are detachably connected to the frame body 1. Two sets of frame bodies 1 are arranged opposite each other. The door frames 5 are detachably connected to the two frame bodies 1 respectively. The seat bucket frame 3 and the rear frame 2 are detachably connected between the rear sides of the two frame bodies 1 respectively, and the rear frame 2 is located above the seat bucket frame 3.

[0023] The frame body 1 has a first connecting lug 8 fixedly connected to its lower rear side, and the seat bucket frame 3 has second connecting lugs 9 on both sides. When the seat bucket frame 3 is assembled between the rear sides of the two frame bodies 1, the first connecting lug 8 and the second connecting lug 9 are joined together and fixedly connected by bolts. The frame body 1 has a third connecting lug 7 fixedly connected to its upper rear side, and the rear frame 2 has fourth connecting lugs 6 on both sides. When the rear frame 2 is assembled between the rear sides of the two frame bodies 1, the third connecting lug 7 and the fourth connecting lug 6 are joined together and fixedly connected by bolts. This design effectively improves assembly flexibility. The modular split frame allows the seat bucket frame 3 and the rear frame 2 to be pre-assembled independently, and then the core load-bearing components are connected by bolts, balancing strength and disassembly, and reducing transportation and maintenance difficulties.

[0024] Meanwhile, one side of the door frame 5 is hinged to the frame body 1. In this example, a hinge mounting area 4 is provided on one side of the door frame 5. When the door frame 5 is assembled into the frame body 1, the door frame 5 is hinged to the frame body 1 in the hinge mounting area 4. This arrangement allows vulnerable parts such as the door frame 5 to be packaged independently during storage and transportation, reducing the damage rate during transportation. At the same time, through the above-mentioned technical means, the frame body 1, seat bucket frame 3, and rear frame 2 are designed as separate units. In terms of processing technology, segmented welding and independent pre-assembly can be carried out, enhancing assembly flexibility. At the same time, the separate and independent frame structure reduces the size of the components, allowing for parallel electrophoretic painting, avoiding the problem of missed areas in the paint of the integrated frame, and reducing the rework rate.

[0025] Furthermore, the modular design of the electric recreational tricycle's frame offers technological advantages not only in manufacturing processes but also in storage and transportation. The modular structure allows for nested stacking during transport, significantly improving space utilization and increasing the load capacity of the transport equipment. From a post-construction maintenance perspective, the modular structure allows for targeted repair of individual parts in case of collision damage, only requiring replacement of the frame section, thus reducing maintenance and return costs.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
