Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, specifically a frame structure that integrates a guardrail and an outer crossbar handle. Background Technology

[0002] In the manufacturing of electric motorcycles, recreational tricycles, and other vehicles, the safety, stability, and production efficiency of the frame are crucial. Traditional frames often use an assembly-type design for the guardrails and outer handlebars, which are assembled using bolts and other connectors. During actual use, these connections are prone to loosening due to continuous bumps and vibrations. Over time, these loose connections can create gaps between the guardrails / handrails and the frame, reducing the overall structural strength. When the vehicle is involved in a collision, it is difficult to effectively disperse the impact force, which can easily damage other parts of the frame and threaten the safety of the rider and passengers. Traditional assembly-type structures require complex assembly processes such as positioning and bolting of multiple components, resulting in low production efficiency and significant time costs. Furthermore, the assembled frame appears fragmented and lacks overall cohesion and aesthetics due to the presence of connecting parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a frame structure that integrates the guard bar and the outer cross armrest. By integrating components through an integrated welding process, the number of bolt connection points is reduced, enhancing the integrity of the frame structure, thereby increasing structural strength and stability. At the same time, it simplifies the production process, saves bolt assembly time, and improves the appearance quality.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a frame structure integrating a guard bar and an outer cross armrest, including a lower frame 1, a seat bucket 5 fixedly connected to the outer wall of the top of the lower frame 1, an upper frame 7 fixedly connected to the outer wall of the lower frame 1 via a reinforcing plate 9, a guard bar 2 fixedly connected to the outer wall of the top of the lower frame 1, a connecting bar 3 fixedly connected to the outer wall of the top of the guard bar 2, light panels 4 symmetrically fixedly connected to the inner wall of the guard bar 2, a wind deflector 14 fixedly connected to the outer wall of the guard bar 2, front bumpers 15 symmetrically arranged on both sides of the wind deflector 14, a foot pedal 12 fixedly connected to the outer wall of the lower frame 1, and anti-slip plates 13 symmetrically arranged on the outside of the foot pedal 12. The reinforcing plate 9 is connected to the lower frame 1 and the upper frame 7 of the frame respectively, enhancing the stability of the overall structure; the wind deflector 14 and the front bumper 15 together provide front-end protection, and the light panel 4 is embedded inside the guard bar 2 to ensure lighting function;

[0019] The seat bucket 5 is provided with a first armrest 6 and a second armrest 11 on both sides. The lower frame 1 is fixedly connected to a first arc-shaped bar 8 and a second arc-shaped bar 10 on both sides. The outer wall of the bottom of the first armrest 6 is fixedly connected to the outer wall of the top of the first arc-shaped bar 8. The outer wall of the bottom of the second armrest 11 is fixedly connected to the outer wall of the top of the second arc-shaped bar 10. The first arc-shaped bar 8 on the right and the second arc-shaped bar on the left are welded to both sides of the lower frame 1 of the frame. Then, the first armrest 6 on the right and the second armrest 11 on the left of the lower frame 1 are welded in sequence. The bottom of the armrest is fixed to the top of the corresponding arc-shaped bar, and the side wall is connected to the upper frame of the frame to form a stable outer armrest structure. Finally, the protective plates on both sides are attached to complete the appearance of the frame structure.

[0020] The side walls of the first handrail 6 and the second handrail 11 are both fixedly connected to the side wall of the upper frame 7. The outer wall of the reinforcing plate 9 is fixedly connected to the outer wall of the lower frame 1 and the outer wall of the upper frame 7, respectively. The outer wall of the front bumper 15 is fixedly connected to the outer wall of the lower frame 1. The outer wall of the anti-slip plate 13 is fixedly connected to the outer wall of the lower frame 1. This reduces the number of connection points of the traditional assembled guardrail, avoiding the decrease in strength due to loose connection parts or bolt quality problems. When the vehicle encounters a collision or bump, it can more efficiently disperse the impact force, protecting other parts of the frame and the driver and passengers. The one-piece welded outer handrail eliminates the connection gap by welding process, making the handrail and the frame a solid whole that can withstand greater external forces. When the vehicle encounters bumps and vibrations, it remains stable and difficult to loosen, providing reliable grip support for the driver and passengers.

[0021] When using this guard bar and the frame structure integrated with the outer handlebar, the lower frame 1, guard bar 2, connecting bar 3, light panel 4, seat bucket 5, upper frame 7, reinforcing plate 9, foot pedal 12, light panel 4, wind deflector 14, and front bumper 15 of this frame are first fixedly connected by welding to form the main frame of the frame. In this step, the reinforcing plate 9 is connected to the lower frame 1 and the upper frame 7 of the frame respectively to enhance the stability of the overall structure; the wind deflector 14 and the front bumper 15 together provide front protection, and the light panel 4 is embedded in the guard bar 2 to ensure the lighting function;

[0022] After welding is completed, the first arc-shaped bar 8 on the right and the second arc-shaped bar on the left are welded to both sides of the lower frame 1 of the frame. Then, the first handrail 6 on the right and the second handrail 11 on the left of the lower frame 1 are welded in sequence. The bottom of the handrail is fixed to the top of the corresponding arc-shaped bar, and the side wall is connected to the upper frame of the frame to form a stable outer handrail structure. Finally, the protective plates on both sides are attached to complete the appearance of the frame structure.

[0023] During use, the integrated structure of the guardrail and the frame reduces the number of connection points of traditional assembled guardrails, avoiding the decrease in strength caused by loose connections or bolt quality issues. When the vehicle encounters a collision or bump, it can more efficiently disperse the impact force, protecting other components of the frame and the occupants. The one-piece welded outer grab handle eliminates connection gaps through welding, making the grab handle and the frame a solid whole that can withstand greater external forces. When the vehicle encounters bumps and vibrations, it remains stable and does not easily loosen, providing reliable grip and support for the occupants. At the same time, the one-piece welding process replaces the traditional assembly method, reducing assembly steps and lowering production time and costs.
