Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a multifunctional scooter mudguard and scooter. Background Technology

[0002] Scooters, as a popular sport and leisure device, are widely used for leisure and transportation due to their small size, portability, moderate speed, ease of learning and operation, and sensitive braking. They also have a good training effect on the developing balance system of teenagers. Common scooters typically have one wheel at the front and one at the back. When riding, the rider stands on the footrest in the middle of the scooter and moves forward by pushing off the ground with their feet or by electric propulsion.

[0003] However, existing electric scooters generally use drum brakes or disc brakes for braking, and these traditional braking methods have some limitations. Drum brakes have a slow braking response, are complex in construction, and have many parts; disc brakes, while providing better braking performance, are prone to locking up and are generally suitable for larger vehicles. For electric scooters that require portability and a simple structure, these braking methods are not very suitable.

[0004] Furthermore, existing scooter braking systems often employ a hand-held brake lever design, which presents several problems. First, the handlebar structure is complex, with exposed brake cables, resulting in a less streamlined appearance. Second, the brake lever force needs to be manually adjusted by changing the length of the brake cable, making consistency difficult to guarantee. Finally, installation is time-consuming. Therefore, there is an urgent need for a scooter mudguard design that is simple in structure, easy to install, and offers excellent braking performance to improve the safety and ease of use of scooters. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-functional scooter mudguard and scooter that is easy to operate and has good safety.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-functional scooter mudguard is provided, including a frame, a mudguard body and a power-off switch; the mudguard body is opposite to the outer circumferential surface of the wheel, one end of the mudguard body is pivotally connected to the frame, and the other end is a free end;

[0007] The frame is equipped with a power-off switch, and a torsion spring is sleeved on the pivot shaft between the mudguard body and the frame. One end of the torsion spring abuts against the inner surface of the mudguard body, and the other end abuts against the frame. The elastic force of the torsion spring causes the mudguard body to elastically abut against the power-off switch.

[0008] The mudguard body has a brake part on its inner surface opposite to the outer circumference of the wheel.

[0009] Furthermore, in the aforementioned multi-functional scooter mudguard, the brake part is formed by the mudguard body being recessed outward from the outer periphery of the wheel, so that the side of the mudguard body facing the wheel forms a brake groove, and the side of the mudguard body away from the wheel forms an anti-slip protrusion.

[0010] Furthermore, in the aforementioned multi-functional scooter mudguard, the brake groove is V-shaped.

[0011] Furthermore, in the aforementioned multi-functional scooter mudguard, the brake part is a brake protrusion provided on the outer peripheral surface of the mudguard body facing the wheel.

[0012] Furthermore, in the aforementioned multi-functional scooter mudguard, the power-off switch is a miniature relay, and it contacts the mudguard body through elastic contacts.

[0013] Furthermore, in the aforementioned multi-functional scooter mudguard, the distance between the mudguard body and the wheel gradually decreases from the pivot end to the free end.

[0014] Furthermore, in the aforementioned multi-functional scooter mudguard, the torsion spring is a stainless steel torsion spring with a wire diameter of 2 mm.

[0015] Furthermore, in the aforementioned multi-functional scooter mudguard, the mudguard body and the brake part are integrally formed.

[0016] Furthermore, in the aforementioned multi-functional scooter mudguard, the mudguard body is installed above the rear wheel of the scooter, and the distance between the brake part and the outer surface of the rear wheel is 2-5 mm.

[0017] Another technical solution provided by this utility model is to provide a scooter, including the above-mentioned multi-functional scooter mudguard.

[0018] The beneficial effects of this utility model are as follows: The multi-functional scooter mudguard not only has the basic function of mud protection, but also integrates braking and power-off functions. When the mudguard is stepped on, the mudguard body rotates towards the wheel and is pressed downwards, thereby allowing the friction between the mudguard and the wheel to prevent the wheel from continuing to rotate, resulting in a better braking effect. Simultaneously, when braking with the mudguard, the mudguard body disengages from the power-off switch, triggering the power-off opening to control the scooter's power cut-off. This, combined with the physical brake, prevents user misoperation, such as continuing to accelerate while braking, further improving the safety of the scooter. Attached Figure Description

[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] This utility model provides a multifunctional scooter mudguard, including a frame, a mudguard body and a power-off switch; the mudguard body is opposite to the outer circumferential surface of the wheel, one end of the mudguard body is pivotally connected to the frame, and the other end is a free end;

[0025] The frame is equipped with a power-off switch, and a torsion spring is sleeved on the pivot shaft between the mudguard body and the frame. One end of the torsion spring abuts against the inner surface of the mudguard body, and the other end abuts against the frame. The elastic force of the torsion spring causes the mudguard body to elastically abut against the power-off switch.

[0026] The mudguard body has a brake part on its inner surface opposite to the outer circumference of the wheel.

[0027] The beneficial effects of this utility model are as follows: The multi-functional scooter mudguard not only has the basic function of mud protection, but also integrates braking and power-off functions. When the mudguard is stepped on, the mudguard body rotates towards the wheel and is pressed downwards, thereby allowing the friction between the mudguard and the wheel to prevent the wheel from continuing to rotate, resulting in a better braking effect. Simultaneously, when braking with the mudguard, the mudguard body disengages from the power-off switch, triggering the power-off opening to control the scooter's power cut-off. This, combined with the physical brake, prevents user misoperation, such as continuing to accelerate while braking, further improving the safety of the scooter.

[0028] Furthermore, in the aforementioned multi-functional scooter mudguard, the brake part is formed by the mudguard body being recessed outward from the outer periphery of the wheel, so that the side of the mudguard body facing the wheel forms a brake groove, and the side of the mudguard body away from the wheel forms an anti-slip protrusion.

[0029] As described above, the brake grooves improve braking performance. The anti-slip protrusions increase pedal friction and guide the user to precise positioning, preventing accidental operation.

[0030] Furthermore, in the aforementioned multi-functional scooter mudguard, the brake groove is V-shaped.

[0031] As described above, the above settings increase the friction coefficient and improve the braking effect.

[0032] Furthermore, in the aforementioned multi-functional scooter mudguard, the brake part is a brake protrusion provided on the outer peripheral surface of the mudguard body facing the wheel.

[0033] As described above, the brake protrusion increases the friction coefficient between the mudguard body and the wheel, thus improving the braking effect.

[0034] Furthermore, in the aforementioned multi-functional scooter mudguard, the power-off switch is a miniature relay, and it contacts the mudguard body through elastic contacts.

[0035] Furthermore, in the aforementioned multi-functional scooter mudguard, the distance between the mudguard body and the wheel gradually decreases from the pivot end to the free end.

[0036] As described above, the above configuration allows the mudguard body to get closer to the wheel during braking, thus increasing the braking effect.

[0037] Furthermore, in the aforementioned multi-functional scooter mudguard, the torsion spring is a stainless steel torsion spring with a wire diameter of 2 mm.

[0038] As described above, a high elastic modulus ensures stable reset force and adapts to frequent operations.

[0039] Furthermore, in the aforementioned multi-functional scooter mudguard, the mudguard body and the brake part are integrally formed.

[0040] As can be seen from the above description, the above settings improve the overall structural strength and durability, and reduce assembly complexity.

[0041] Furthermore, in the aforementioned multi-functional scooter mudguard, the mudguard body is installed above the rear wheel of the scooter, and the distance between the brake part and the outer surface of the rear wheel is 2-5 mm.

[0042] As described above, the above settings optimize the brake contact distance, ensuring rapid response and avoiding friction in non-braking states.

[0043] Another technical solution provided by this utility model is to provide a scooter, including the above-mentioned multi-functional scooter mudguard.

[0044] Example 1

[0045] Please refer to Figure 1 and Figure 2 As shown, a multi-functional scooter mudguard includes a frame 1, a mudguard body 2, and a power-off switch 3; the mudguard body 2 is opposite to the outer circumferential surface of the wheel, one end of the mudguard body 2 is pivotally connected to the frame 1, and the other end is a free end;

[0046] The frame 1 is equipped with a power-off switch 3. A torsion spring 4 is sleeved on the pivot shaft between the mudguard body 2 and the frame 1. One end pin of the torsion spring 4 abuts against the inner surface of the mudguard body 2, and the other end pin abuts against the frame 1. The elastic force of the torsion spring 4 causes the mudguard body 2 to elastically abut against the power-off switch 3.

[0047] The mudguard body 2 has a brake part on its inner surface opposite to the outer circumference of the wheel.

[0048] The brake part is formed by the mudguard body 2 being recessed outward from the outer periphery of the wheel, so that the side of the mudguard body 2 facing the wheel forms a brake groove 21, and the side of the mudguard body 2 away from the wheel forms an anti-slip protrusion. The brake groove 21 is V-shaped.

[0049] The distance between the mudguard body 2 and the wheel gradually decreases from the pivot end to the free end. The mudguard body 2 and the brake are integrally formed. The mudguard body 2 is installed above the rear wheel of the scooter, and the distance between the brake and the outer surface of the rear wheel is 2-5 mm.

[0050] The usage method of the above-mentioned multi-functional scooter mudguard is as follows:

[0051] When braking is needed, the user simply steps on the mudguard. Under pressure, the mudguard rotates towards the wheel and is pressed downwards. Friction is generated between the mudguard and the wheel, stopping the wheel's rotation and achieving a braking effect. During braking, the high friction between the brake grooves on the mudguard and the wheel increases braking force; simultaneously, the multi-point contact design of the brake unit avoids braking resistance, improving braking efficiency. After braking is complete, the torsion spring returns the mudguard to its original position, the power switch resets, and the scooter resumes normal operation.

[0052] This multi-functional scooter mudguard integrates mud-blocking, braking, and power-off functions. While ensuring basic mud-blocking functions, it achieves fast and reliable braking effects, avoiding many shortcomings of traditional drum brakes or disc brakes. It has the advantages of simple structure, convenient operation, and excellent braking performance, and is especially suitable for compact, electrically driven scooters.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
