New description: [New technical field] [0001] This creation is a front-wheel suspension structure for electric vehicles, especially when the current wheel is subjected to excessive impact, which can prevent the suspension member from being damaged before being damaged. Earthquake structure. [Prior Art] [0002] Electric vehicles are suitable for people with limited mobility or physical disabilities, so that the above-mentioned people can move freely, so electric vehicles can be used on outdoor streets in addition to indoor use, however, outdoors. The road surface on the street is usually awkward, which makes the ride on the electric car worse, and in the case of potholes or high and low undulating roads, there may be opportunities for tilting and overturning due to unstable center of gravity. [New content] [0003] In order to prevent the electric vehicle from driving on the road surface of the outdoor street, it is possible to encounter the road surface and have the problem of reducing the ride comfort, and the danger of tilting the car, this creation provides a front wheel. The suspension structure has the function of buffering and absorbing the impact force of the front wheel, thereby providing the occupant with better riding comfort and reducing the risk of rollover. [0004] The above function can be achieved by a kind The front wheel suspension structure of the electric vehicle includes a front wheel base, and a top surface extending downwardly and having a space, the top surface of the top surface is connected with a rotating shaft, and the top surface is downwardly extended with two upper protruding columns respectively adjacent to the foregoing two a side surface, wherein the two side surfaces are respectively provided with an arc groove to form an impact surface with the side surface, the arc form number A0101, page 3 / total 15 pages M417314 [0005] [0006] [0007] [0008] [0009 [0011] [0011] The form apostrophe A0101 groove includes a - first perforation and a second perforation, the second perforation has a fixed rod; the two pivotal pieces respectively correspond to the above two a side surface, the female dragging piece includes an arc end surface corresponding to the impact surface, the pivoting piece is adjacent to the arc end surface and is provided with a first opening corresponding to the first perforation, and a long opening corresponding sleeve Provided on the fixing rod, the pivoting piece is disposed at one end of the arc end surface, and has a second opening, and a second opening corresponding to the second opening, and a lower protruding column corresponding to the upper protruding column ; the front wheel is located between the two side faces of the front wheel seat; the axle, the wearer is the second opening of the pivoting piece and the front wheel; and the two springs are respectively sleeved on the corresponding ones a crown and the lower protrusion. The distance between the impact surface of the front wheel base and the arc end surface of the pivoting piece is smaller than the length of the long opening. The pivoting piece is rotated upward to cause the fox end face to strike the impact surface of the arc groove. The front wheel suspension structure of the electric vehicle further includes a fixed shaft corresponding to the first opening of the front wheel seat and the first opening of the pivoting piece. One or a combination of the fixed shaft, the fixed rod or the axle is a screw. The effect of this creation: 1. Reduce the impact of the front wheels by the shock-absorbing structure, thereby improving the ride comfort and avoiding the danger of rollover. 2. By the impact surface being able to withstand the end face of the arc, the front wheel is absorbed by the impact force of the front wheel while preventing the damage of the suspension member. [Embodiment] The technical features and enhancements of the present invention can be clearly presented in conjunction with the preferred embodiments of the following drawings. First, referring to the first and second figures, the preferred embodiment of the present invention, The utility model relates to a front wheel suspension structure for an electric vehicle, comprising: [0013] a front wheel base (1) comprising a top surface (11) extending downwardly with two spaced sides (12), the top surface (11) upwards A rotating shaft (J3) is connected to connect the frame of the electric vehicle, so that the front wheel base (1) is rotated, and the top surface (11) extends downwardly with two upper protrusions (14) respectively adjacent to the two sides. (12) 'The foregoing two sides (12) are respectively provided with an arc groove (121) to form an impact surface (15) with the side surface (12), and the arc groove (121) includes a first perforation ( 122) and a second through hole (123), the second through hole (123) is fixedly fixed with a fixing rod (2). [0014] a plug piece (3) 'correspondingly connected to the two side faces (12), each pivot piece (3) includes an arc end face (31) corresponding to the impact surface (15), the pivoting A first opening (32) and a long opening (33) are disposed adjacent to the arc end surface (31), and a fixed shaft (4) is correspondingly disposed through the first opening (32). And the first through hole (122) of the front wheel base (1), such that the pivot piece (3) is rotated on the side (12) of the front wheel base (1), and the long opening (33) Correspondingly disposed on the fixing rod (2), the sway range of the pivoting piece (3) is restricted through the long opening (33), and the impact surface (15) of the front wheel base (1) is The distance between the arc end faces (31) of the pivoting piece (3) is smaller than the length of the long opening hole (33), and the pivoting piece (3) is provided with a second end from one end of the arc end surface (31). The opening (34), the form number A0101, the fifth page, the M417314, and the lower end of the second opening (34) extend upwardly with a lower protruding post (35) corresponding to the upper projection (14). a front wheel (5), located on the two sides (丨2) of the front wheel base (1), an axle (6), which is disposed through the second opening of the pivoting piece (3) and the front wheel ( 5), the front wheel (5) is pivotally connected to the pivoting piece (3) to be controlled by the rotation of the front wheel base (1). Two springs (Ό, respectively sleeved to the corresponding upper tenon (14) and the lower protrusion (35), such that the pivot piece (3) is subjected to the tension of the spring (7) The upper opening (33) is placed above the fixing rod to form a suspension structure. [0018] wherein the fixing rod (2), the fixed shaft (4) and the axle (6) may be screws Referring to the third figure, when the front wheel (5) is affected by the pothole or the uneven terrain, the front wheel (5) is rotated upward with the fixed shaft (3) as a fulcrum, and is compressed at the same time. The spring (7) achieves the purpose of suspension by the spring (the tension of the spring buffering the vibration of the front wheel (5). It is worth mentioning that 'see the fourth figure' when the front wheel (5) When the instantaneous collision force is too large, the pivoting piece (3) is rapidly rotated upwardly to cause the spring (7) to be quickly compressed to reduce the buffering effect while causing the long opening (33) to quickly collide. The fixing rod (2) may overwhelm the fixing rod (2) and the long opening (33) over time to cause deformation, so Referring to the fifth figure, the arc end face (31) is caused to impact the arc groove (121) by the upward rotation of the cabinet tab (3). Form No. A0101 Page 6 of 15 Face (15), to prevent the underside of the long opening (33) from colliding with the solid; (dry) (2), and reduce the instantaneous impact force to achieve the effect of damping, while solving the fixed axis ( 2) and the problem that the long opening (33) is subjected to excessive force and is broken or broken is a preferred design.
