Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, and in particular relates to a front riser structure for electric vehicles that facilitates adjustment of the trailing distance. Background Technology

[0002] Electric vehicles are vehicles powered by electricity, which is converted into mechanical energy by an electric motor to drive the vehicle. The front seat tube (often called the "fork seat tube" or "head tube") of an electric vehicle is a key component at the front of the frame, mainly used to connect the handlebars, fork, and frame, and to provide steering and support.

[0003] The trail distance of the electric vehicle front seat tube is a key geometric parameter affecting the vehicle's steering stability and handling, and is closely related to the angle of the front seat tube and the design of the front fork. Currently, there are many types of electric vehicle front seat tube structures on the market. For example, a front seat tube structure for electric vehicles with easy trail distance adjustment has been published on the China Patent Network with the publication number CN210212643U. This type of electric vehicle front seat tube structure can flexibly adjust the trail distance of the electric vehicle, but it has some defects and shortcomings that need to be improved: (1) Although some existing electric vehicle front seat tube structures can adjust the trail distance through the gear adjustment hole, the hole spacing of the gear adjustment hole is often small, which limits the adjustment accuracy of the trail distance, making it difficult to achieve stepless adjustment, and it is impossible to intuitively grasp the specific trail distance adjustment data; (2) Some existing electric vehicle front seat tube structures lack effective wire management measures. The relevant wires are often directly exposed, which is easily damaged by impact or causes safety hazards. Furthermore, when adjusting the trail distance, the wires may become tangled or worn due to the angle adjustment, thus affecting the normal use of the electric vehicle. Therefore, in response to the above problems, the electric vehicle front riser structure provided by this utility model, which facilitates the adjustment of the trailing distance, is of great significance. Utility Model Content

[0004] This utility model provides an electric vehicle front strut structure that facilitates easy adjustment of the trail distance. The trail distance can be adjusted by changing the angle between the frame tube and the front strut. The interaction between the adjustment hole and the limiting post allows for stepless adjustment of the angle between the frame tube and the front strut, thus making the adjustment accuracy of the trail distance unlimited. During the adjustment process, the angular deflection between the frame tube and the front strut can be observed in real time through the scale, providing a more intuitive and visual understanding of the specific trail distance adjustment data. The relevant wires on the electric vehicle can pass through the corresponding wiring cavities on each wiring seat. The wiring cavities can manage and hide the wires to reduce the risk of exposure and effectively prevent the wires from tangling or wearing. In summary, this invention solves the problems in the background technology.

[0028] Please see Figure 1-6As shown, this utility model discloses an electric vehicle front strut structure for easy adjustment of trail distance, including a front strut body 1 and a frame body 2. Wiring seats 3 are fixedly connected to both outer walls of the front strut body 1. The wiring seats 3 are symmetrically distributed, and each wiring seat 3 has several wiring cavities 4. The relevant wires of the electric vehicle can pass through the corresponding wiring cavities 4 on each wiring seat 3. The wiring cavities 4 allow for management and concealment of the wires, reducing the risk of exposure and effectively preventing tangling or wear between wires. A first adjusting seat 5 is installed on one side of the front strut body 1, and a pair of positioning studs 6 are fixedly connected to the side of the front strut body 1 near the first adjusting seat 5. Positioning nuts 7 are threaded onto the positioning studs 6. A pair of positioning holes 8 are provided on the first adjusting seat 5, and first fastening holes 9 are provided on both sides of the first adjusting seat 5. Limiting posts 10 are fixedly connected to both outer walls of the first adjusting seat 5. The frame... One end of the tube body 2 is fixedly connected to a second adjusting seat 11. The second adjusting seat 11 has a second fastening hole 12 and a pair of adjusting holes 13 on both sides. Each limiting post 10 passes through the corresponding adjusting hole 13. A fastening screw 14 is inserted into the second fastening hole 12. A pair of fastening nuts 15 are threaded onto the fastening screw 14. When the fastening screw 14 passes through the corresponding second fastening hole 12 and first fastening hole 9 on the second adjusting seat 11 and the first adjusting seat 5, the second adjusting seat 11 and the first adjusting seat 5 are hinged together. At this time, the second adjusting seat 11 can drive the frame tube body 2 to deflect around the first adjusting seat 5, thereby adjusting the angle between the frame tube body 2 and the front riser tube body 1 to adjust the trail distance. After the adjustment is completed, the fastening nuts 15 are threaded onto both ends of the fastening screw 14 and tightened to fasten the angle between the frame tube body 2 and the front riser tube body 1.

[0029] The adjustment holes 13 are arc-shaped and symmetrically distributed above and below the second fastening holes 12. The width of the adjustment holes 13 is equal to the diameter of the limiting post 10. When the second adjusting seat 11 drives the frame tube 2 to deflect around the first adjusting seat 5, each adjustment hole 13 can move along the path of the limiting post 10. At this time, the mutual cooperation between the adjustment holes 13 and the limiting post 10 can play a limiting and guiding role, so as to improve the connection stability between the frame tube 2 and the front upright tube 1. At the same time, the mutual cooperation between the adjustment holes 13 and the limiting post 10 can realize the stepless adjustment of the angle between the frame tube 2 and the front upright tube 1, so that the adjustment accuracy of the trailing distance is not limited.

[0030] The second adjustment seat 11 has a pair of scales 16 on both outer walls. The position of each scale 16 corresponds to the position of each adjustment hole 13. The angle deflection between the frame tube 2 and the front riser tube 1 can be observed in real time through the scales 16, so that the specific trailing distance adjustment data can be grasped more intuitively and visually.

[0031] Both the first adjusting seat 5 and the second adjusting seat 11 are C-shaped. The outer wall of the first adjusting seat 5 near the front riser body 1 is arc-shaped, and the width of the outer wall of the first adjusting seat 5 is equal to the width of the inner wall of the second adjusting seat 11. When the first adjusting seat 5 is installed on the front riser body 1, it can fit tightly against the outer wall of the front riser body 1. When the second adjusting seat 11 is installed on the first adjusting seat 5 by means of a hinge connection, the second adjusting seat 11 can fit tightly against the outer side of the first adjusting seat 5 to play a limiting role, thereby effectively preventing the second adjusting seat 11 from shaking and tilting when deflected.

[0032] The diameters of the first fastening hole 9 and the second fastening hole 12 are both equal to the diameter of the fastening screw 14. A pair of washers 17 are fitted on the fastening screw 14. The washers 17 are annular and are located between the outer wall of the second adjusting seat 11 and the fastening nut 15. The washers 17 can increase the contact area between the fastening nut 15 and the second adjusting seat 11, so that the preload is evenly distributed and local stress concentration is reduced. In addition, the washers 17 can also isolate the fastening nut 15 from the second adjusting seat 11 to avoid direct contact that could cause thread scratches or wear on the surface.

[0033] The diameter of the positioning hole 8 is equal to the diameter of the positioning stud 6, and the center of each positioning hole 8 corresponds one-to-one with the center of each positioning stud 6. When the first adjusting seat 5 is attached to the outer wall of the front riser tube body 1, each positioning stud 6 can be aligned and pass through the corresponding positioning hole 8. At this time, the positioning nut 7 is threaded onto each positioning stud 6 and tightened. The first adjusting seat 5 can be fixedly installed on the front riser tube body 1 through the mutual cooperation between the positioning stud 6, the positioning hole 8, and the positioning nut 7.

[0034] The wiring cavity 4 is circular and is distributed linearly at equal intervals along the length of the wiring base 3. Each wiring cavity 4 has an anti-wear sleeve 18 on its inner wall. The anti-wear sleeve 18 is cylindrical and its outer diameter is equal to the inner diameter of the wiring cavity 4. The anti-wear sleeve 18 can be made of elastic materials such as rubber and is fixed by adhesives. The anti-wear sleeve 18 can play a role in anti-wear protection to prevent the wire from directly contacting the inner wall of the wiring cavity 4 and causing wear.

[0035] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0036] The working principle of this utility model is as follows:

[0037] In use, the second adjusting seat 11 can drive the frame tube 2 to rotate around the first adjusting seat 5, thereby adjusting the angle between the frame tube 2 and the front riser tube 1 to adjust the trailing distance. When the second adjusting seat 11 drives the frame tube 2 to rotate around the first adjusting seat 5, each adjusting hole 13 can move along the path of the limiting post 10. At this time, the interaction between the adjusting holes 13 and the limiting post 10 can play a limiting and guiding role, thereby improving the connection stability between the frame tube 2 and the front riser tube 1. At the same time, the interaction between the adjusting holes 13 and the limiting post 10 can realize stepless adjustment of the angle between the frame tube 2 and the front riser tube 1, so that the adjustment accuracy of the trailing distance is not affected by the angle between the frame tube 2 and the front riser tube 1. During the adjustment process, the angle deflection between the frame tube 2 and the front riser tube 1 can be observed in real time through the scale 16, so that the specific trail distance adjustment data can be grasped more intuitively and visually. After the adjustment is completed, the fastening nuts 15 are threaded to both ends of the fastening screw 14 and tightened to tighten the angle between the frame tube 2 and the front riser tube 1. Both sides of the outer wall of the front riser tube 1 are fixedly connected to the wiring seat 3. Each wiring seat 3 has several wiring cavities 4. The relevant wires on the electric vehicle can pass through the corresponding wiring cavities 4 on each wiring seat 3. At this time, the wiring cavities 4 can be used to manage and hide the wires to reduce the risk of exposure, and at the same time, it can effectively prevent the wires from getting tangled or worn.
