Description

Technical Field

[0001] This invention patent relates to the technical field of shock absorption for electric scooters, and more specifically, to an external shock absorption device for electric scooters. Background Technology

[0002] Electric scooters are a new type of skateboarding product following traditional skateboards. Scooters include pedals, front and rear wheels, a pole, and handlebars mounted on the top of the pole. The combination of the handlebars and the pole enables the scooter to be controlled and steered, making it a very effortless exercise device.

[0003] Currently, electric scooters include shock absorbers to improve riding comfort. For example, a prior patent with authorization announcement number CN 218198676U discloses a shock-absorbing structure and an electric scooter, including a support member, a left cantilever, a right cantilever, and a shock absorber. The support member has a hinge portion and a first shock absorber mounting portion located above the hinge portion. The left and right cantilever arms each have a second shock absorber mounting portion between one end and the other end. The upper end of the shock absorber is disposed on the first shock absorber mounting portion, and the lower end of the shock absorber is disposed on the second shock absorber mounting portions of the left and right cantilever arms. Of the first and second shock absorber mounting portions, one is fixedly connected to the shock absorber, and the other includes a sliding groove. The corresponding upper or lower end of the shock absorber extends into the sliding groove through a connecting shaft and can selectively slide along the sliding groove to change its position. The current position of the connecting shaft is fixed by a locking member to adjust the tilt angle of the shock absorber's buffer direction line relative to the vertical line.

[0004] In the existing technology, the vibration force of the wheel is transmitted to the connecting shaft through the cantilever, and then to the shock absorber through the connecting shaft. As a result, the shock absorber is affected by the installation position, which limits the shock absorber's damping stroke and affects the shock absorber's damping effect. Summary of the Invention

[0011] Furthermore, the first arm includes two first arm plates and a screw fastener. The inner ends of the two first arm plates clamp the first frame rod, and the outer ends of the two first arm plates form the first frame portion. The screw fastener synchronously passes through the two first arm plates and the first frame rod, and the rotation of the screw fastener is used to fix or unlock the two first arm plates and the first frame rod.

[0012] Furthermore, along the direction toward the first damping member, the cross-sectional area of ​​the first arm plate is arranged in a gradually decreasing manner.

[0013] Furthermore, the first boom includes two first boom platforms, which are arranged in a one-to-one correspondence with the two first boom segments and are laid flat and connected.

Moreover, the wheel components transmit vibration force to the first and second shock absorber frames, causing them to swing relative to the frame components, facilitating the transmission of vibration force to the first and second shock absorbers and ensuring timely and effective shock absorption. Additionally, the limited travel of the first and second shock absorbers allows for longer travel, resulting in a gentler and more effective shock absorption. Attached Figure Description

[0028] Reference Figure 1-8The image shows a preferred embodiment of the present invention.

[0029] An external electric scooter shock absorption device includes a frame 1, a first shock absorber 2, a second shock absorber 3, a first shock absorber 4, a second shock absorber 5, and a wheel 6. The lower part of the first shock absorber 2 and the lower end of the second shock absorber 3 are respectively assembled with the two sides of the wheel 6. The upper part of the first shock absorber 2 forms a first frame portion, and the upper part of the second shock absorber 3 forms a second frame portion. The first shock absorber 2 and the second shock absorber 3 are respectively hinged to the frame 1. The frame 1 has a first support portion and a second support portion. The first frame portion is located above the first support portion. The two ends of the first shock absorber 4 are respectively assembled with the first frame portion and the first support portion. The second frame portion is located above the second support portion. The two ends of the second shock absorber 5 are respectively assembled with the second frame portion and the second support portion.

[0030] The aforementioned external shock absorption device for electric scooters, with the combined action of the first shock absorber 4 and the second shock absorber 5, provides dual shock absorption, improving the shock absorption effect and driving comfort. Furthermore, both the first shock absorber 4 and the second shock absorber 5 are externally mounted, facilitating maintenance and replacement. Additionally, the wheel assembly 6 transmits vibration force to the first shock absorber frame 2 and the second shock absorber frame 3, causing them to swing relative to the frame assembly 1. This facilitates the transmission of vibration force to the first shock absorber 4 and the second shock absorber 5, ensuring timely and effective shock absorption. Moreover, the limited travel of the first shock absorber 4 and the second shock absorber 5 allows for a longer travel distance, resulting in a gentler and more effective shock absorption.

[0031] The first damping component 4 and the second damping component 5 are used to suppress the oscillation when the spring absorbs shock and rebounds, as well as the impact from the road surface, to achieve the damping effect.

[0032] The first shock absorber frame 2 includes a first frame rod 21 and a first frame arm 22. The lower part of the first frame rod 21 is assembled with the wheel component 6, and the upper part of the first frame rod 21 is connected to the inner end of the first frame arm 22. The first frame rod 21 extends upward at an angle, and the first frame arm 22 extends downward at an angle. The outer end of the first frame arm 22 forms the first frame section.

[0033] Thus, since the first boom 22 extends downwards at an angle, it facilitates the transmission of road impact force to the first shock absorber 4, ensuring the shock absorption effect. Furthermore, since the first pole 21 extends upwards at an angle, it facilitates the assembly of the first pole 21 and the first boom 22. At the same time, it facilitates the transmission of road impact force from the wheel assembly 6 to the first pole 21, then to the first boom 22, and finally to the first shock absorber 4, ensuring the shock absorption effect.

[0034] The frame component 1 includes a frame body 11, a first fork 12 and a second fork. The first fork 12 and the second fork are respectively assembled with the frame body 11. The first fork 12 is hinged to the first frame rod 21. The first fork 12 includes a first fork segment 121, which is arranged in an arc shape. The lower part of the first fork segment 121 forms a first support.

[0035] In this way, since the first fork segment 121 is arranged in an arc shape, the bearing capacity of the first fork segment 121 is improved, and the service life of the first fork segment 121 is increased. At the same time, the first fork 12 and the first frame rod 21 are hinged. When the first frame rod 21 is affected by the impact force of the road surface, it swings relative to the first fork 12, and transmits the impact force of the road surface to the first shock absorber 4 to achieve the shock absorption effect.

[0036] The first fork segment 121 includes two first fork plates, which are arranged in an arc shape and are arranged at intervals. The two first fork plates clamp the first frame rod 21 and are hinged to the first frame rod 21. The first support includes two first support plates, the lower part of the first fork plate forms the first support plate, and the two first support plates clamp the lower parts of the two first shock absorbers 4.

[0037] This increases the assembly area between the first fork and the first frame 21, improving the assembly stability of the first fork and the first frame 21, and also enhances the contact area between the first fork and the first shock absorber 4, thus improving the assembly stability of the first fork and the first shock absorber 4.

[0038] The first arm 22 includes two first arm pieces 221 and a fastener 222. The inner ends of the two first arm pieces 221 clamp the first support rod 21, and the outer ends of the two first arm pieces 221 form the first support portion. The fastener 222 passes through the two first arm pieces 221 and the first support rod 21 simultaneously. The fastener 222 rotates to fix or unlock the two first arm pieces 221 and the first support rod 21.

[0039] Under the action of the first arm piece 221, the assembly stability of the first arm 22 and the first support rod 21 is improved. The two first arm pieces 221 and the first support rod 21 can be fixed or unlocked by the fastener 222. When in use, they are fixed. When it is necessary to adjust the tilt angle of the first arm 22, the first arm piece 221 and the first support rod 21 can be unlocked by the fastener 222, thereby adjusting the tilt angle of the first arm 22 and thus adjusting the damping strength of the first shock absorber 4 to meet the driving needs of different users.

[0040] Along the direction toward the first damping member 4, the cross-sectional area of ​​the first arm piece 221 is arranged in a gradually decreasing manner. This facilitates the transmission of impact or vibration force along the direction of the first damping member 4, while reducing the relative sway of the first arm piece 221, improving the transmission stability of impact or vibration force, and helping to improve the concentration of the transmission direction of impact or vibration force, thus facilitating the transmission of impact or vibration force along the direction of the first damping member 4.

[0041] The first boom 22 includes two first boom platforms 223, which correspond one-to-one with two first boom segments 221 and are arranged flat and connected. The first boom platforms 223 are arranged in a protruding manner in the direction away from the first boom segments 221. The first boom platforms 223 are cylindrical and have a first toothed portion 224 arranged in a ring around their outer periphery. The first rod 21 has two rod grooves, and the two first boom platforms 223 are respectively embedded in the two rod grooves. The rod grooves have rod teeth 211, and the first toothed portion 224 is meshed with the rod teeth 211.

[0042] In this way, the assembly stability of the first arm 22 and the first rod 21 is improved through the cooperation of the first toothed part 224 and the rod toothed part 211.

[0043] The first toothed part 224 is made of silicone and has a certain degree of elasticity. When adjustment is needed, a rotational force is applied to overcome the meshing force between the first toothed part 224 and the rod toothed part 211, thereby adjusting the tilt angle of the first arm 22.

[0044] Before leaving the factory, the tilt angle of the first arm 22 can be selected based on the user's height. The adjustment of the tilt angle of the first arm 22 is not a frequent operation, and users generally do not need to adjust it when using the electric scooter.

[0045] Along the top-to-bottom direction, the first frame and the first support are arranged at an angle to facilitate the differentiation of the impact and vibration forces transmitted from different directions by the wheel component 6, thus ensuring the shock absorption effect.

[0046] The first shock absorber 2 and the frame component 1 are arranged in a scissor shape to facilitate the transmission of impact and vibration forces to the first shock absorber 4, thereby improving the user's driving comfort.

[0047] The first support pole 21 includes a first upper pole section 212, a first middle pole section 213, and a first lower pole section 214. The first upper pole section 212, the first middle pole section 213, and the first lower pole section 214 are sequentially connected and integrally formed. The first middle pole section 213 is arranged in an arc shape. The first upper pole section 212 and the first lower pole section 214 are staggered. Two first arm plates 221 clamp the first upper pole section 212, and the frame connecting shaft 62 passes through the first lower pole section 214. In this way, the load-bearing capacity of the first support pole 21 is improved, thereby improving the service life of the first support pole 21.

[0048] The second shock absorber frame 3 includes a second frame rod 31 and a second frame arm. The lower part of the second frame rod 31 is assembled with the wheel component 6. The first frame rod 21 and the second frame rod 31 are arranged opposite each other along the wheel component 6. The upper part of the second frame rod 31 is connected to the inner end of the second frame arm. The second frame rod 31 extends upward at an angle, and the second frame arm extends downward at an angle. The outer end of the second frame arm forms the second frame section.

[0049] In this way, since the second boom extends downwards, it is easy for the second boom to transmit the road impact force to the second shock absorber 5, ensuring the shock absorption effect. Furthermore, since the second rod 31 extends upwards, it is easy for the second rod 31 to be assembled with the second boom. At the same time, it is easy for the wheel assembly 6 to transmit the road impact force to the second rod 31, then to the second boom, and finally to the second shock absorber 5, ensuring the shock absorption effect.

[0050] The second fork includes a second fork segment, which is arranged in an arc shape, and the lower part of the second fork segment forms a second support.

[0051] In this way, the second fork section is arranged in an arc shape, which improves the load-bearing capacity and service life of the second fork section; at the same time, the second fork and the second frame rod 31 are arranged in a hinged manner. When the second frame rod 31 is affected by the impact force of the road surface, it swings relative to the second fork, which transmits the impact force of the road surface to the second shock absorber 5, thereby achieving the shock absorption effect.

[0052] The second fork section includes two second fork plates, which are arranged in an arc shape and are arranged at intervals. The two second fork plates clamp the second frame rod 31, and the two second fork plates are hinged to the second frame rod 31. The second support section includes two second support plates, the lower part of the second fork plates forms the second support plate, and the two second support plates clamp the lower parts of the two second shock absorbers 5.

[0053] This increases the assembly area between the second fork and the second frame 31, improving the assembly stability of the second fork and the second frame 31, and also enhances the contact area between the second fork and the second shock absorber 5, thus improving the assembly stability of the second fork and the second shock absorber 5.

[0054] The second arm includes two second arm plates and a fastener 222. The inner ends of the two second arm plates clamp the second frame rod 31, and the outer ends of the two second arm plates form the second frame portion. The fastener 222 passes through the two second arm plates and the second frame rod 31 simultaneously. The fastener 222 rotates to fix or unlock the two second arm plates and the second frame rod 31.

[0055] The second boom plate enhances the assembly stability of the second boom and the second support rod 31. The two second boom plates and the second support rod 31 can be fixed or unlocked by the fastener 222. When in use, they are fixed. When it is necessary to adjust the tilt angle of the second boom, the second boom plate and the second support rod 31 can be unlocked by the fastener 222, thereby adjusting the tilt angle of the second boom and thus adjusting the damping strength of the second shock absorber 5 to meet the driving needs of different users.

[0056] Along the direction toward the second damping member 5, the cross-sectional area of ​​the second arm plate is arranged in a gradually decreasing manner. This facilitates the transmission of impact or vibration force along the direction of the second damping member 5, while reducing the relative sway of the second arm plate, improving the transmission stability of impact or vibration force, and helping to improve the concentration of the transmission direction of impact or vibration force, thus facilitating the transmission of impact or vibration force along the direction of the second damping member 5.

[0057] The second boom includes two second boom platforms, which are arranged in a one-to-one correspondence with the two second boom segments and are laid flat and connected. The second boom platforms are arranged in a protruding manner in the direction away from the second boom segments. The second boom platforms are arranged in a cylindrical shape and have a second platform toothed portion arranged in a ring on the outer periphery. The second boom rod 31 has two rod grooves, and the two second boom platforms are respectively embedded in the two rod grooves. The rod grooves have rod teeth 211, and the second platform teeth and rod teeth 211 are arranged in a meshing manner.

[0058] In this way, the assembly stability of the second arm and the second rod 31 is improved through the cooperation between the second toothed part and the rod toothed part 211.

[0059] The second toothed part is made of silicone and has a certain degree of elasticity. When adjustment is needed, a rotational force is applied to overcome the meshing force between the second toothed part and the rod toothed part 211, thereby adjusting the tilt angle of the second arm.

[0060] Before leaving the factory, the tilt angle of the second arm can be selected based on the user's height. Adjusting the tilt angle of the second arm is not a frequent operation, and users generally do not need to adjust it when using the electric scooter.

[0061] Along the top-to-bottom direction, the second frame and the second support are arranged at an angle to facilitate the differentiation of the impact and vibration forces transmitted from different directions by the wheel component 6, thus ensuring the shock absorption effect.

[0062] The second shock absorber 3 is arranged in a scissor shape with the frame component 1, which facilitates the transmission of impact and vibration forces to the second shock absorber 5, thereby improving the user's driving comfort.

[0063] The second support pole 31 includes a second upper pole section, a second middle pole section, and a second lower pole section. The second upper pole section, the second middle pole section, and the second lower pole section are sequentially connected and arranged as two integral parts. The second middle pole section is arranged in an arc shape. The second upper pole section and the second lower pole section are staggered. Two second arm plates clamp the second upper pole section, and the frame connecting shaft 62 passes through the second lower pole section. In this way, the load-bearing capacity of the second support pole 31 is improved, thereby improving the service life of the second support pole 31.

[0064] Along the top-to-bottom direction, the first shock absorber 4 and the second shock absorber 5 are arranged in a gradually inclined manner towards the rear. This facilitates the first boom 22 to transmit the ground impact force or vibration force to the first shock absorber 4, and facilitates the second boom to transmit the ground impact force or vibration force to the second shock absorber 5, thereby ensuring the overall shock absorption effect.

[0065] The first shock absorber 4 and the second shock absorber 5 are arranged in an aligned manner, making the overall electric scooter more balanced and improving the user's driving comfort.

[0066] The wheel assembly 6 includes a wheel body, a motor assembly, and a frame connecting shaft 62. The wheel body and the motor assembly are assembled together. The motor assembly drives the wheel body to rotate. The frame connecting shaft 62 passes through the wheel body and the motor assembly simultaneously. Both ends of the frame connecting shaft 62 form axle cut portions. The two axle cut portions are assembled with the first shock absorber 2 and the second shock absorber 3, respectively. The axle cut portion has an axle cut surface 621, which extends along the length direction. The axle cut surface 621 is laid flat and in contact with the first shock absorber 2 or the second shock absorber 3.

[0067] In this way, the drive of the motor unit does not affect the frame coupling 62. Under the action of the axial section 621, the assembly stability of the wheel component 6 with the first shock absorber 2 and the second shock absorber 3 is improved, ensuring driving safety. At the same time, the ground impact force or vibration force is transferred to the first shock absorber 2 and the second shock absorber 3 through the frame coupling 62. Regardless of the magnitude of the impact force or vibration force, it is transferred to the first shock absorber 2 and the second shock absorber 3, and finally the shock absorption effect is achieved through the first shock absorber 4 and the second shock absorber 5, ensuring the user's driving comfort.

[0068] The wheel body includes a wheel rim 61, which surrounds the motor assembly. The motor assembly includes a main component and multiple mounting blocks 63. The main component is used to increase the driving force to drive the wheel body. The mounting blocks 63 are arranged at intervals along the circumference of the main component, and the two ends of the mounting blocks 63 are respectively connected to the main component and the wheel rim 61. In this way, the main component and the wheel rim 61 are assembled. At the same time, the use of individual mounting blocks 63 helps to reduce costs and overall weight.

[0069] The mechanical fixing block 63 has a top surface that is arranged in an arc shape. The top surface of the block is laid flat and in contact with the wheel frame 61, which increases the contact area with the wheel frame 61 and improves the fixing effect.

[0070] The outer periphery of the main component is provided with multiple machine protrusions 65, which extend along the axial direction and penetrate through the machine fixing block 63, thereby improving the bearing capacity of the machine fixing block 63 and improving the assembly stability of the main component and the wheel frame 61.

[0071] The machine protrusion 65 and the machine fixed block 63 are integrally formed, which facilitates production and assembly.

[0072] The motor assembly includes multiple reinforcing blocks 64, each reinforcing block 64 and each mechanical fixing block 63 are arranged in a one-to-one correspondence. The inner end of the reinforcing block 64 is arranged perpendicularly to the mechanical fixing block 63, and the outer end of the reinforcing block 64 extends along the axial direction of the main component. Under the action of the reinforcing blocks 64, the bearing capacity of the mechanical fixing block 63 is improved, and the assembly stability of the main component and the wheel frame 61 is improved.

[0073] The top of the reinforcing block 64 is arranged to meet the wheel frame 61, so that the mechanical fixing block 63, the reinforcing block 64 and the wheel frame 61 are combined and connected to form a whole, which improves the overall load-bearing capacity and thus improves the assembly stability of the main component and the wheel frame 61.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
