Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, specifically to an extended seat frame. Background Technology

[0002] Motorcycles, as a convenient and flexible means of transportation, are widely used in urban commuting, rural travel, and leisure activities. With the continuous expansion of the motorcycle market and the increasing diversification of consumer demands, the industry continues to grow.

[0003] In existing technologies, motorcycle seat frames typically lack an effective expansion mechanism, making it impossible to adjust the seat length according to the rider's body size, riding habits, or the size of the items carried. Furthermore, some motorcycle seat frames are cumbersome and inconvenient to install and remove.

[0004] For example, Chinese patent CN215097979U, entitled "A Motorcycle Seat Backrest Structure," while employing a slider and spring design to adjust the backrest position, primarily focuses on adjusting the backrest itself. It doesn't offer an effective solution for the overall expandability and flexibility of the seat frame. Therefore, this structure falls short when accommodating two riders or carrying large items, failing to meet the diverse needs of consumers. Utility Model Content

[0005] The present invention aims to provide an expandable seat frame to solve the technical problem that existing motorcycle seat frames are significantly lacking in expandability and flexibility.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an extendable seat frame, comprising two symmetrically arranged slide rails, with mounting strips extending along the length of the slide rails fixedly provided on the inner side of the two slide rails, the mounting strips having multiple mounting holes for fixed connection with the vehicle body or seat cushion; multiple reinforcing rods provided between the two mounting strips; and a sliding groove for slidingly installing extension accessories on the outer side of the slide rails, the groove opening width being smaller than the inner groove width, and multiple fixing holes provided at the bottom of the groove for bolting the extension accessories.

[0007] The principle and advantages of this solution are as follows: In practical application, this expandable seat frame constructs its basic structure through two symmetrically arranged slide rails and mounting strips fixed to their inner sides. Multiple mounting holes on the mounting strips facilitate a secure connection with the vehicle body or seat, ensuring the stability of the seat frame. Multiple reinforcing rods between the two mounting strips enhance the overall strength and rigidity of the seat frame, enabling it to withstand greater weight and pressure. The sliding groove design on the outer side of the slide rails is used for sliding installation of expansion accessories, and the groove opening width is smaller than the inner groove width, effectively preventing expansion accessories from falling off during sliding. Multiple fixing holes at the bottom of the groove secure the expansion accessories with bolts, achieving flexible expansion of the seat frame. This solution solves the problems of insufficient expandability and poor flexibility of existing motorcycle seat frames, allowing for seat length adjustment according to the rider's body type, riding habits, or the size of carried items. It also makes installing and removing expansion accessories more convenient, meeting diverse consumer needs.

[0008] Preferably, as an improvement, the front end of the slide rail is provided with a reverse surface, and the front part of the slide rail is provided with a snap-fit ​​mounting groove for forming a tight fit with the corresponding snap-fit ​​component of the vehicle body or seat structure.

[0009] The benefits of this improvement are: the snap-fit ​​mounting slot allows for more precise and rapid positioning and securing of the seat frame when installed on the vehicle body. The sloping surfaces enhance the vehicle's streamlined aesthetics while also improving driver comfort, allowing the legs to rest naturally on either side of the seat frame.

[0010] Preferably, as an improvement, the front ends of the two slide rails are inwardly wrapped geometrically, and the snap-fit ​​mounting groove is formed by the front end of the mounting strip and the inner side of the inwardly recessed front end of the slide rail.

[0011] The beneficial effects of this improvement are as follows: the front ends of the two slide rails have an inwardly wrapping geometric shape, and the snap-fit ​​mounting groove is formed by the front end of the mounting strip and the inner side of the inward-curving front end of the slide rail. This design further enhances the strength and stability of the snap-fit ​​mounting groove. The inwardly wrapping shape can better wrap and fix the snap-fit ​​components, making the connection between the seat frame and the vehicle body tighter and less prone to loosening due to external factors. At the same time, this integrated design also improves the overall aesthetics and structural integrity of the seat frame.

[0012] Preferably, as an improvement, the rear end of the slide rail is provided with a taillight mounting slot between the two slide rails.

[0013] The beneficial effects of this improvement are as follows: the taillight mounting slot located between the two rails at the rear end of the slide rail provides a dedicated position for installing the motorcycle taillight. This not only facilitates the installation and fixation of the taillight, making the taillight layout more reasonable and aesthetically pleasing, but also ensures the stability and safety of the taillight during riding. Furthermore, integrating the taillight mounting slot into the seat frame avoids the hassle of drilling additional holes or installing brackets on the vehicle body, simplifying the overall structure and installation process of the motorcycle.

[0014] Preferably, as an improvement, the end of the groove at the front end of the slide rail is closed, and the end of the groove at the rear end of the slide rail is open.

[0015] The beneficial effects of this improvement are as follows: the closed end of the slide groove at the front of the slide rail prevents the expansion accessory from sliding out of the front of the groove during forward sliding, thus providing a limiting and protective function. Conversely, the open end of the slide groove at the rear of the slide rail facilitates the installation and removal of the expansion accessory from the rear, improving operational convenience. This design with different front and rear ends ensures the safety of the expansion accessory during sliding while also meeting the installation and removal needs in practical use.

[0016] Preferably, as an improvement, there are two reinforcing rods, and the two reinforcing rods are set at a preset distance apart.

[0017] The beneficial effects of this improvement are: it allows for the rational distribution of stress while ensuring the overall strength of the seat frame, preventing structural deformation or damage caused by excessive local stress. At the same time, this spaced-out design also reduces the weight of the seat frame, lowers material costs, and improves its economy and practicality.

[0018] Preferably, as an improvement, the extended accessories include a chair back, a seat mounting assembly, and a storage rack.

[0019] The beneficial effects of this improvement are as follows: the extended accessories, including seat backs, seat mounting components, and storage racks, greatly expand the functionality and usage scenarios of the seat rack. The seat back can be installed and adjusted according to the rider's needs, providing a more comfortable riding experience; the seat mounting components allow for easy installation of child seats and other equipment, meeting the needs of family travel; and the storage rack can be used to place luggage and other items, increasing the motorcycle's carrying capacity. This diverse range of extended accessories allows the motorcycle seat rack to adapt to different usage scenarios and user needs, improving the product's versatility and market competitiveness.
