[0021] As Figures 1 to 3 shown, this embodiment provides a self-locking fixing structure for electronic components on an automotive windshield, including a front windshield bracket 1, on which there is a component 2, and the component is clamped on the front windshield bracket by an eccentric clamping assembly 3 provided on the front windshield bracket.

[0022] The structure of using an eccentric clamping assembly to clamp the components on the front windshield bracket is not only simple, but also firmly pressed, and the disassembly and assembly of the components are simple, efficient, and not easily loosened or failed.

[0023] In the embodiment of the utility model, the eccentric clamping assembly includes a swing arm 5 hinged on the front block bracket via a rotating shaft 4, the swing arm is in an "L" shape, one end of the swing arm is a pressing end 6, and the other end is eccentrically fixed with a pressing head 7.

[0024] In an embodiment of the utility model, the pressing end faces inward and is located between the top surface of the component and the bottom surface of the front block bracket, the pressing head is located on the outer side of the component, and the rotating shaft extends forward and backward.

[0025] In the embodiment of the utility model, the swing arm is fixedly provided with a first buckle 8 on the other side away from the pressing end, and the front block bracket is fixedly provided with a second buckle 9 beside the first buckle.

[0026] In the embodiment of the utility model, the eccentric clamping assembly is arranged on two opposite sides of the component.

[0027] In the embodiment of the utility model, the eccentric clamping assembly is arranged on two opposite sides behind the component.

[0028] In the embodiment of the utility model, two opposite sides of the component are both fixedly provided with embedded protrusions 10 at the front and rear, and the pressing head is pressed and abutted against the corresponding embedded protrusions at the rear of the component.

[0029] In the embodiment of the utility model, the front barrier bracket is provided with an embedding recess 11 for embedding a front embedding protrusion of a component, and the notches 12 of the embedding recess are all facing rearward.

[0033] In the embodiment of the present utility model, the working principle of the self-locking fixing structure for electronic components on the automotive windshield is as follows: Before assembling the components, the eccentric clamping assembly is pre-assembled on the front windshield bracket, and the first and second buckles are engaged with each other, making the swing arm unable to swing inward temporarily. When assembling the components, the embedding protrusion in front of the component first obliquely inserts into the embedding recess through the notch, and then the rear end of the component is pressed against the front windshield bracket, causing the component to press against the pressing end of the swing arm. At this time, the first and second buckles are disengaged, and under the pressing of the component, the swing arm swings inward to make the pressing head press against the embedding protrusion behind the component, forming a pressing force. When the direction of the pressing force is on the connection line between the pressing head and the rotating shaft, the swing arm is self-locked, realizing the fixing of the component.

[0034] The above is only the preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes.
