DETAILED DESCRIPTION

[0016] The utility model will be further explained in combination with the drawings.

[0017] Refer to Figures 1-2As shown, the vehicle energy-saving headlamp comprises a lamp shell body 1, a lamp cover body 2 arranged on the lamp shell body 1, and an energy-saving lamp body 3 arranged inside the lamp cover body 2. The outer periphery of the lamp cover body 2 is horizontally extended outward to form a first mounting portion 201. The outer periphery of the lamp shell body 1 is horizontally extended outward to form a second mounting portion 101. The outer periphery of the second mounting portion 101 is upwardly folded to form a flange 102. The bottom end of the first mounting portion 201 abuts against the top end of the second mounting portion 101. The outer side wall of the first mounting portion 201 abuts against the inner side wall of the flange 102. The lamp cover body 2 and the lamp shell body 1 can be adhered together by a sealing glue. A sealing groove 4 is arranged at the connection between the lamp shell body 1 and the lamp cover body 2. The sealing groove 4 is arranged on the second mounting portion 101.

[0018] A sealing gasket 5 is arranged inside the sealing groove 4. An expansion groove 501 is arranged inside the sealing gasket 5. A bearing seat 6 is arranged at the bottom end of the sealing gasket 5. A connecting column 7 is arranged at the top end of the bearing seat 6 and extends into the expansion groove 501 to tightly abut the inner walls of the sealing groove 4 on both sides of the sealing gasket 5. The inner dimension of the expansion groove 501 is smaller than the outer diameter of the connecting column 7. After the connecting column 7 enters the expansion groove 501, the connecting column 7 is flared to expand the sealing gasket 5 on both sides, so that the sealing gasket 5 tightly abuts the inner walls of the sealing groove 4 on both sides. The gap space between the sealing gasket 5 and the inner walls of the sealing groove 4 is prevented. A containing groove 8 is arranged inside the sealing groove 4 and communicates with the sealing groove 4. A spring 9 is arranged inside the containing groove 8. The containing groove 8 is matched with the spring 9 to prevent the spring 9 from deviating during deformation. The top end of the spring 9 abuts against the bottom end of the bearing seat 6. Under the action of the spring 9, the top end of the sealing gasket 5 tightly abuts the bottom end of the connection between the lamp cover body 2 and the lamp shell body 1. When the bottom end of the first mounting portion 201 abuts against the top end of the second mounting portion 101, the sealing gasket 5 is extruded to move into the sealing groove 4. The bearing seat 6 moves to one end of the containing groove 8 to extrude the spring 9 to elastically deform. The reverse force generated by the spring 9 tightly abuts the bottom end of the first mounting portion 201 with the sealing gasket 5. The spring 9 always applies a pushing force to tightly abut the sealing gasket 5 at the connection. The sealing gasket 5 tightly abuts the sealing groove 4 and the first mounting portion 201. The gap space between the sealing gasket 5 and the sealing groove 4 is prevented. The sealing performance between the lamp shell body 1 and the lamp cover body 2 is improved. The water vapor outside is prevented from entering the vehicle lamp from the connection between the lamp cover and the shell body to improve the service life and working stability of the vehicle lamp.

[0019] Preferably, the top end of the connecting column 7 is provided with a driving surface 701 in a circular arc structure. The driving surface 701 in the circular arc structure facilitates the connecting column 7 to enter the expansion groove 501. The bottom end of the sealing gasket 5 is provided with an opening for the connecting column 7 to enter the expansion groove 501.

[0020] Preferably, when the lamp shell body 1 is not connected with the lampshade body 2, the sealing washer 5 is higher than the upper surface of the sealing groove 4 under the force of the spring 9, the top surface of the spring 9 extends to the inside of the sealing groove 4 when the lamp shell body 1 is not connected with the lampshade body 2, and the spring 9 is pressed to the inside of the accommodating groove 8 when connected.

[0021] Preferably, the lamp shell body 1 is internally provided with a mounting plate 10, the mounting plate 10 is provided with a reflecting bowl 11, and the energy-saving lamp body 3 is arranged on the mounting plate 10 inside the reflecting bowl 11.

[0022] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification or equivalent change made according to the technical essence of the present application to the above embodiment falls within the protection scope of the present application.
