Description
Technical Field
The utility model relates to an automobile parts makes technical field, in particular to lens joint structure.
Background
The lens is also called as astigmatic glass, which is made by pressing transparent glass and is a combination of a plurality of special prisms and lenses. The automobile lens is one of three components of an automobile lamp and mainly has the function of refracting parallel light beams reflected by a reflector so as to ensure that the front road surface of the automobile has good and uniform illumination. In the current assembling process of automobile lamps, lens is an indispensable part of automobile lamps. Although the lens plays an important role in an automobile lamp, the structure and the assembly process of the lens are simple, the current installation mode of the lens is mainly welding and fixing by PUR glue, and the fixing mode has the problems of unstable fixation and improper assembly.
In view of the current assembly problems of lens, some solutions have been proposed by those skilled in the automotive field. CN208170278U discloses a mounting structure of daytime driving lamp lens, its key technical point lies in: the front end at the lens lamp body sets up the mounting groove, and the bottom of mounting groove is equipped with first welding muscle, and the rear edge of lens is equipped with second welding muscle, second welding muscle and first welding muscle welding. The technical scheme solves the problem of welding and fixing the PUR glue, but the welding operation is complex and the cost is higher.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims at providing a lens clamping structure with simple structure and obvious effect, wherein the lamp shell is provided with a bayonet with a trapezoidal cross section, the inner wall of the bayonet extends downwards to form a clamping groove with an inverted trapezoidal longitudinal section; be provided with on the lens with bayonet socket, draw-in groove assorted buckle, the buckle includes the connecting piece, first joint spare, second joint spare, and the connecting piece extends to bayonet socket department and forms first joint spare, and the connecting piece extends to the draw-in groove bottom along the inclined plane of draw-in groove, forms second joint spare, and second joint spare is provided with the stopper with connecting piece joint portion.
Preferably, the bayonet and the clamping groove are integrally formed, and a step for limiting the second clamping piece up and down is arranged at the bottom of the clamping groove.
Preferably, buckle integrated into one piece, stopper setting are between draw-in groove inclined plane and second joint spare, and the arc is personally submitted with the contact on draw-in groove inclined plane to the stopper.
Effective gain: the utility model is provided with the buckle, the clamping groove and the bayonet, so that the second clamping piece of the buckle can be conveniently installed in the clamping groove, and the first clamping piece is clamped on the bayonet to limit the movement of the lens in the up-and-down direction; the arrangement of the limiting block is beneficial to the sliding of the lens on the inclined surface of the clamping groove when the lens is installed, and the limiting block limits the clamping buckle in the horizontal direction after the lens is installed; the cooperation of bayonet socket, draw-in groove, first joint spare, second joint spare, stopper makes the lens can stabilize the joint on the lamp body, has realized the assembly of lens.
Drawings
FIG. 1 is a sectional view of the present invention;
in the figure, 1-bayonet, 2-clamping groove, 21-step, 3-buckle, 31-connecting piece, 32-first clamping piece, 33-second clamping piece and 4-limiting block.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
A bayonet 1 with a trapezoidal cross section is arranged on a lamp shell, the inner wall of the bayonet 1 extends downwards to form a clamping groove 2 with an inverted trapezoidal longitudinal section, and the bayonet 1 and the clamping groove 2 are integrally formed. Be provided with on the lens with bayonet 1, draw-in groove 2 assorted buckle 3, 3 integrated into one piece of buckle, buckle 3 includes connecting piece 31, first joint spare 32, second joint spare 33. For making things convenient for the mould shaping and saving cost, the utility model discloses in, the connecting piece 31 of design becomes the bar, and connecting piece 31 extends to bayonet socket 1 department and forms first joint spare 32, and connecting piece 31 extends to draw-in groove 2 bottom along draw-in groove 2's inclined plane, forms second joint spare 33, and whole buckle 3 is down "r" type. Second joint spare 33 is provided with stopper 4 with connecting piece 31 joint portion, stopper 4 is provided with the protrusion of step form with the connecting portion of connecting piece 31, stopper 4 is personally submitted the arc with the contact on 2 inclined planes of draw-in groove, stopper 4's arc setting is favorable to stopper 4 slip on 2 inclined planes of draw-in groove, be favorable to the installation of second joint spare 33, stopper 4 sets up between 2 inclined planes of draw-in groove and second joint spare 33, it is spacing to the removal on the horizontal direction of second joint spare 33, thereby realize spacing on the horizontal direction to buckle 3. The bottom of the clamping groove 2 is provided with a step 21 for limiting the upper part and the lower part of the second clamping piece 33, and the step 21 is matched with the bayonet 1 to realize the limiting of the clamping buckle 3 in the vertical direction.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for the ordinary skilled in the art, the specific implementation and the application range can be changed according to the embodiment of the present invention,
