Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an anti-drop metal connector for electric vehicles. Background Art

[0002] Electric vehicles are also called "electric vehicles". They are pure electric vehicles powered by batteries and driven by electric motors (DC, AC, series excitation, external excitation). With the continuous innovation of electric vehicle technology in recent years, they have been widely popularized in my country. In the assembly process of electric vehicles, metal connectors are usually required to connect the handlebars with the shock absorbers installed on both sides of the front wheels to control the steering of the front wheels.

[0003] At present, during the assembly process of some electric vehicles, in order to control the steering of the front wheels by turning the handlebars, it is necessary to use metal connectors at the connection between the handlebar rod and the shock absorber installed on the front wheel, which can be installed more conveniently and quickly.

[0004] When existing electric vehicles connect the handlebars to the shock absorber through metal connectors, some of them only use one bolt to fix the shock absorber. However, since electric vehicles often encounter bumpy roads on the road, as the vehicle continues to bump, the shock absorber may suddenly fall off during driving and separate from the metal connector, causing personal injury to the driver. It may also cause looseness during long-term use, which increases the driving risk after long-term riding. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide an anti-drop metal connector for electric vehicles, which can solve the problem of loosening and falling off after long-term bumping.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-slip metal connector for electric vehicles, comprising a connector body, the upper surface of the connector body is fixedly connected to a steering column, a buffer is arranged at the bottom of the connector body, a hole is provided on the outer surface of a telescopic rod of the buffer, a device box is fixedly connected to the bottom of the connector body, a first cavity is provided inside the device box, the first cavity extends out of the front and rear side surfaces of the device box, a collar is provided on the front and rear sides of the first cavity, the collar is fixedly sleeved on the outer surface of the telescopic rod of the buffer, a movable plate is fixedly connected to the outer surface of the collar, the other side of the movable plate extends into the first cavity and slides with the first cavity, one side of the movable plate located in the first cavity is rotatably connected to the first rotating plate, the other side of the first rotating plate One side is rotatably connected to a second displacement block, the other side of the second displacement block is fixedly connected to a connecting rod, the other end of the connecting rod is fixedly connected to the displacement block, the bottom surface of the displacement block is fixedly connected to a second sliding rod, the upper surface of the displacement block is fixedly connected to a third sliding rod, two third sliding grooves are provided on the top inner wall of the first cavity, a second cavity is provided in the device box, the third sliding groove is communicated with the second cavity, two fourth sliding rods are slidably connected in the second cavity, the other end of the third sliding rod extends into the second cavity through the third sliding groove, the third sliding rod slides in the third sliding groove, one end of the third sliding rod located in the second cavity is fixedly connected to the fourth sliding rod, the other end of the fourth sliding rod slides through the outer surface of the device box, and the fourth sliding rod is adapted to the dug hole.

[0007] Preferably, two first slide grooves are provided on the left and right inner walls of the first cavity, a sliding rod is sleeved on the second displacement block, and the other end of the sliding rod extends into the first slide groove and slides with the first slide groove.

[0008] Preferably, two communication grooves are provided on the connector body, a fixing ring is fixedly connected in the communication groove, and thread teeth are provided inside the fixing ring.

[0009] Preferably, the upper end of the buffer extends into the connecting groove and contacts the lower surface of the fixing ring, a first bolt is provided at the top of the connecting groove, and a threaded hole is also provided on the telescopic rod of the buffer.

[0010] Preferably, the bottom of the first bolt is threadedly connected to the threaded teeth of the fixing ring and the threaded hole on the buffer telescopic rod respectively.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The anti-slip metal connector of the electric vehicle, during the installation process of the electric vehicle, the steering column is installed on the top of the connector body, and then the buffer is installed on the bottom of the connector body, and then the ring is set on the outside of the thin rod of the buffer, and the fastening bolt is tightened into the threaded groove of the fixed plate to make the two fixed plates move relative to each other, so that the ring is fixed on the buffer. When the buffer falls off downward with the connector body, the ring moves downward synchronously, driving the movable plate to move downward horizontally. The movable plate causes one end of the first rotating plate to have an angular displacement. Since the length of the first rotating plate is a fixed value, the other end of the first rotating plate pulls the second displacement block to move horizontally toward the outside of the device box. During the downward movement of the movable plate, the sliding rod limits the second displacement block, so that the second displacement block cannot move downward synchronously with the movable plate and can only move horizontally. When the second displacement block moves horizontally, The displacement block is driven to move synchronously by the connecting rod, and the second sliding rod slides in the second sliding groove, and the third sliding rod slides in the third sliding groove, and the displacement block is limited at the same time to prevent the displacement block from shifting left and right. During the movement of the displacement block, the third sliding rod pushes the fourth sliding rod to move while moving along the third sliding groove, so that the length of the fourth sliding rod sliding out of the device box increases, until the fourth sliding rod enters the hole opened in the buffer, and limits the buffer to prevent the buffer from completely falling off the connecting part body. Through the above method, the device can limit the buffer in time when the buffer is loose and detached, and avoid the buffer from falling off and falling on the ground as much as possible, thereby causing the vehicle to roll over. This minimizes the probability of safety hazards after long-term driving, improves the practicability and stability of the device, and maximizes the convenience of maintenance of the electric vehicle.

[0013] (2) When the electric vehicle is installed, the buffer rod is first extended into the connecting groove and released from the fixing ring, and then the first bolt is screwed into the buffer through the fixing ring to fix the buffer. In this way, the connection stability between the devices is improved as much as possible during the assembly of the electric vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
