[0002] Battery cars are also called "electric cars". They are pure electric vehicles that are powered by batteries and then driven by electric motors. In recent years, they have been widely popularized in my country. In the assembly process of existing electric cars, buffers are generally installed on both sides of the front wheels. At the same time, in order to control the steering of the front wheels by turning the handlebars, the buffers and the steering column need to be connected together through three-hole connectors, so that the direction of movement of the car can be controlled by turning the handlebars.

[0007] Preferably, the lower end of the threaded rod rotates through the inside and is rotatably connected to the bottom wall of the first cavity, and a second stabilizing plate is threadedly sleeved on the outer surface of the threaded rod located in the first cavity.

[0008] Preferably, a through groove is formed on the inner wall of the two communicating grooves, the through groove is communicated with the first cavity, and sliding rods are provided on the front and rear sides of the second stabilizing plate, and the other end of the sliding rod extends into the through groove and slides with the through groove.

[0009] Preferably, holes are formed on the two buffers, and one end of the sliding rod away from the second stabilizing plate extends into the hole and fits in the hole.

[0010] Preferably, a third rotating rod is rotatably connected between the sliding rod and the second stabilizing plate.

[0011] Preferably, two first L-shaped rods are fixedly connected to the upper surface of the connector body, the two first L-shaped rods are respectively arranged on both sides of the steering column, and the lower surface of the first L-shaped rod cross bar contacts the upper surface of the buffer telescopic rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The three-hole connector for the front wheel of the electric vehicle is easy to install. The threaded rod is rotated to make the stabilizing plate move downward. During the downward movement of the stabilizing plate, the two rotating rods are tilted at an angle. The ends of the two rotating rods connected to the sliders push the two sliders to move toward each other. During the relative movement of the sliders, the two second sliders are driven to move relative to each other synchronously through the connecting rod. During the relative movement of the two second sliders, the second rotating rod has a constant diameter. As the second slider moves, the supporting rod is pulled to tilt toward the direction of the steering column. During the downward movement of the stabilizing plate, the fifth rotating rod is tilted at an angle, pushing the fourth slider to slide along the third slide groove toward the direction of the steering column. During the movement, the second connecting rod The rod pulls the third slider to move along the second slide groove synchronously, and the movement of the third slider pulls the fourth rotating rod to produce an angle tilt, pulling the second support rod to tilt toward the direction of the steering column. In the process of the support rod and the second support rod tilting toward the direction of the steering column, the contact plate and the second contact plate first contact the outer surface of the steering column. When the stabilizing plate moves downward to a suitable position, as the support rod and the second support rod continue to tilt, the contact plate and the second contact plate make the side surface of the steering column close to the steering column fit the steering column. Through the above method, the stability of the steering column of the electric vehicle during driving is improved as much as possible, the probability of the steering column bending when subjected to inertia is reduced as much as possible, the practicality of the device is improved, and the service life of the device is increased.

[0014] (2) The three-hole connector for the front wheel of an electric vehicle which is easy to install, during the assembly process of the electric vehicle, first fix the steering column to the upper surface of the connector body, and then slide the top ends of the two buffers into the connecting grooves. When the top of the buffer telescopic rod contacts the first L-shaped rod, the threaded rod is rotated to make the stabilizing plate and the second stabilizing plate move downward synchronously. During the downward movement of the second stabilizing plate, the third rotating rod is moved downward synchronously. Since the diameter of the third rotating rod remains unchanged, the sliding rod is pushed to slide along the through groove toward the connecting groove during the downward movement of the second stabilizing plate. When the second stabilizing plate moves downward to a suitable position, the sliding rod slides into the hole opened on the buffer to limit the buffer. In the above manner, during the alignment process of the buffer, the buffer is limited to avoid the device from slipping out of the three-hole connector as much as possible, thereby improving the convenience of buffer installation, while minimizing the workload of the staff and improving the stability of the device.
