[0036] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms "a," "an" and "the" are intended to include plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0037] Hereinafter, the terms "first" and "second" are used only for the purpose of description and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0038] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0039] Referring to Figures 1 to 3 As shown, the detachable vehicle front structure includes a frame 1, a vehicle front connecting piece 4, and a front fork connecting piece 9.

[0040] Referring to Figure 1 and Figure 3 As shown, the end of the frame 1 is provided with a first connecting part 2, which is configured as a protrusion 3 extending in the opposite direction of the body of the frame 1.

[0041] Referring to Figure 2 and Figure 3 As shown in the figure, the front connecting piece 4 is provided with a connecting groove 7 and a connecting channel 8, which can be detachably inserted into the first connecting part 2 through the connecting groove 7, and fixed with the protrusion 3 through a screw.

[0042] Referring to Figure 1 and Figure 2 As shown in the figure, the front connecting piece 9 is used to connect the front fork 10 at one end and the handlebar 11 at the other end, and is rotatably inserted into the connecting channel 8. This design not only improves the detachability and stability of the front structure, but also facilitates maintenance and replacement.

[0043] Referring to Figures 1 to 3 As shown in the figure, it should be noted that the end of the frame 1 is provided with a first connecting part 2, which is a protrusion 3 extending in the opposite direction of the frame 1 body. This design of the protrusion 3 makes the front connecting piece 4 more stable when inserted into the frame 1, and reduces the loosening phenomenon caused by vibration. The shape of the protrusion 3 can be rectangular, circular or other suitable geometric shapes, depending on the matching requirements of the front connecting piece 4. For example, if a rectangular protrusion 3 is selected, the contact area can be increased to improve stability; if a circular protrusion 3 is selected, the manufacturing difficulty can be reduced and the production cost can be reduced.

[0044] When the shape of the protrusion 3 is rectangular, the outer end of the protrusion 3 is provided with a rounded corner to avoid scratching the parts during installation.

[0045] In addition, the rectangular protrusion 3 can also be designed to have an acute angle between its extension direction and the end face of the frame 1. This design can increase the contact area between the protrusion 3 and the front connecting piece 4, and provide a stable support point.

[0046] In addition, the protrusion 3 is provided with a first through hole, both ends of the first through hole are threaded, and the front connecting piece 4 is provided with a second through hole corresponding to the first through hole. The screw is inserted into the first through hole and the second through hole from both sides of the protrusion 3 to realize fixation and facilitate disassembly.

[0047] It should be noted that in order to avoid the thread from slipping due to repeated disassembly and assembly, the screw is loose and not tightly installed. A detachable sleeve is installed in the first through hole of the protrusion 3, and the screw is threadedly connected with the sleeve.

[0048] The front end connecting piece 4 is provided with a connecting groove 7 and a connecting channel 8, which can be detachably inserted into the first connecting part 2 through the connecting groove 7. The shape and size of the connecting groove 7 need to match the protrusion 3 to ensure good insertion effect. The connecting groove 7 is internally provided with a guide rib, which plays a role in guiding the protrusion 3 to smoothly enter the connecting groove 7 during insertion, avoiding deviation or jamming. The guide rib can extend from one end of the connecting groove 7 to the other end, or can only be arranged in the middle of the connecting groove 7, which can be adjusted according to actual use. For example, if you want the insertion process to be smoother, you can choose a longer guide rib; if you are worried that the guide rib is too long to affect the strength, you can choose a shorter guide rib.

[0049] The outer side of the front end connecting piece 4 is provided with a limiting part 5 for limiting the screw. The limiting part 5 can be in the form of a groove 6, located on both sides of the front end connecting piece 4. The advantage of this design is that it can prevent the screw from shifting during tightening, ensuring the reliability of the fixation. The limiting part 5 can also take other forms, such as a protrusion or a baffle, as long as it can play a limiting role. For example, if you want the limiting part 5 to have better anti-slip effect, you can choose a textured surface; if you are worried that the limiting part 5 will affect the appearance, you can choose a hidden design.

[0050] The front fork connecting piece 9 is used to connect the vehicle front fork 10 at one end and the vehicle handle 11 at the other end, and is rotatably inserted into the connecting channel 8. The material of the front fork connecting piece 9 can be selected from high-strength lightweight materials such as aluminum alloy and carbon fiber to reduce weight and improve durability. The connecting channel 8 of the front fork connecting piece 9 is internally provided with a sealing element, which can be made of rubber ring or other materials with good elasticity, used to prevent dust and water from entering the connecting channel 8 and prolong the service life. The thickness and hardness of the sealing element need to be adjusted according to the actual situation to ensure that it can effectively seal without affecting the rotating flexibility of the front fork connecting piece 9.

[0051] The implementation principle of the embodiment is that the combination of the protrusion 3 on the frame 1 and the connecting groove 7 of the front end connecting piece 4 realizes the quick installation and disassembly of the front end structure. The reverse extension design of the protrusion 3 increases the friction during insertion, improving the stability. The guide rib in the connecting groove 7 further enhances the insertion accuracy and avoids deviation. The design of the limiting part 5 ensures the reliable fixation of the screw and prevents loosening. The rotating design of the front fork connecting piece 9 and the application of the sealing element not only ensure the flexibility of operation, but also improve the overall protection performance. Overall, this detachable front end structure not only simplifies the maintenance and replacement process, but also significantly improves the safety and durability, meeting the diversified needs of modern transportation tools.

[0052] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
