[0027] The frame 1 is an integrated structure, the front axle assembly 2 is fixedly connected to the frame 1 by welding, the front axle body 21 is a central sleeve structure, used to load the steering wheel shaft of the scooter, the bottom of the front axle body 21 is fixedly connected to the frame 1 by welding, and the bottom of the frame 1 is connected to the middle of the front axle body 21.

[0028] The two ends of the suspension component 3 are respectively connected to the front axle component 2 and the front wheel mounting seat 5, so as to realize the installation of the front wheel mounting seat 5 on both sides of the front axle component 2. At the same time, through the setting of the shock absorbing component 4, when the front wheel mounting seat 5 is subjected to vibration, the shock absorbing component 4 is used to absorb the vibration, thereby ensuring the stability of the frame 1 and the front axle body 21.

[0029] A support rod 11 connected to the front axle assembly 2 is formed in the middle of the frame 1. The front axle body 21 and the suspension connector 22 are both connected to the support rod 11. The support rod 11 is arranged along the length direction of the frame 1. The two suspension connectors 22 located on both sides of the front axle body 21 are welded and fixed to the opposite sides of the support rod 11.

[0030] The front axle body 21 is vertically arranged, and the bottom of the front axle body 21 is welded and fixed to the support rod 11, the suspension connecting piece 22 is horizontally arranged, and the suspension connecting piece 22 is welded and fixed to the opposite sides of the support rod 11, and a plurality of connecting plates 24 connected to the suspension connecting piece 22 and the support rod 11 are welded on the side of the front axle body 21, and the plurality of connecting plates 24 are arranged around the circumferential direction of the front axle body 21.

[0031] The connecting plate 24 connected to the front axle body 21 and the support rod 11 is used to strengthen the connection between the front axle body 21 and the support rod 11, and the connecting plate 24 connected to the front axle body 21 and the suspension connecting member 22 is used to strengthen the connection between the front axle body 21 and the suspension connecting member 22.

[0032] An opening is formed at the bottom of the suspension connector 22 for socketing the suspension component 3, and a fastening bolt 7 connected to the suspension component 3 is provided on the suspension connector 22. The suspension component 3 can be loaded through the bottom opening of the suspension connector 22, and the height support of the suspension component 3 is achieved under the action of the fastening bolt 7.

[0033] The suspension assembly 3 includes a suspension body 31 and a support seat 32 welded to the end of the suspension body 31. The suspension body 31 is sleeved in the suspension connector 22, so that there is a larger contact area between the suspension body 31 and the suspension connector 22, thereby facilitating the transmission of vibrations with the suspension body 31. A fixing seat 33 for installing the shock absorbing assembly 4 is welded on the suspension body 31.

[0034] The fixed seat 33 and the connecting seat 23 are respectively connected to the opposite ends of the shock absorbing assembly 4. The fixed seat 33 and the connecting seat 23 are both provided with a connecting pin 6 rotatably connected to the shock absorbing assembly 4. Under the action of the connecting pin 6, the two ends of the shock absorbing assembly 4 can respectively rotate with the fixed seat 33 and the connecting seat 23, thereby realizing the extension and retraction of the shock absorbing assembly 4 during the rotation of the suspension assembly 3 to achieve a shock absorbing effect.

[0035] The shock absorbing assembly 4 includes a telescopic shaft 41 and a shock absorbing spring 42 sleeved on the telescopic shaft 41, and two ends of the telescopic shaft 41 are provided with limit baffles 43 respectively abutting against the two ends of the shock absorbing spring 42. When the suspension assembly 3 vibrates, the fixed seat 33 is driven to vibrate, so that the relative position of the fixed seat 33 and the connecting seat 23 changes, and the length of the telescopic shaft 41 and the shock absorbing spring 42 is changed, so that shock absorption is achieved under the action of the shock absorbing spring 42.

[0036] The front wheel mounting seat 5 is connected to the support seat 32, and the front wheel mounting seat 5 includes a mounting body 51 and a mounting shaft 52 connected to each other. The mounting body 51 is sleeved on the support seat 32, and the mounting shaft 52 is horizontally arranged. The mounting body 51 can rotate around the support seat 32, and the wheel body is installed on the mounting shaft 52, so that the rotation of the mounting body 51 drives the wheel body to rotate, thereby realizing the steering of the scooter.

[0037] The support seat 32 is a vertically arranged cylindrical structure, and the top and bottom of the installation body 51 are respectively formed with a support plate 53 and a drive plate 54 arranged at the upper and lower ends of the support seat 32. The support plate 53 and the drive plate 54 are provided with a connecting bolt 56 that passes through the support seat 32, and the side of the installation body 51 is also formed with a limit plate 55 for limiting the rotation angle of the installation body 51.

[0038] The support plate 53 and the drive plate 54 are used to clamp the support seat 32, so as to support the height of the front wheel mounting seat 5, and form a rotating shaft located in the support seat 32 by setting the connecting bolt 56, and realize the overall rotation of the mounting body 51 by pushing and pulling the drive plate 54.

[0039] During actual use, when the wheel body of the front wheel mounting seat 5 contacts the ground and vibrates, the vibration is transmitted to the suspension assembly 3 through the front wheel mounting seat 5, causing the suspension body 31 and the fixing seat 33 of the suspension assembly 3 to vibrate synchronously, thereby changing the relative position of the fixing seat 33 and the connecting seat 23, thereby changing the length of the telescopic shaft 41 and the shock-absorbing spring 42, and achieving shock absorption under the action of the shock-absorbing spring 42, thereby reducing the vibration received by the frame 1 and the front axle assembly 2.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
