Description

Technical Field

[0001] The utility model relates to the technical field of welcome lamps, in particular to a car welcome lamp. Background Art

[0002] Car welcome lights, also known as "courtesy lights" or "door lights", are an additional lighting function designed to enhance the riding experience. When the car door is opened, they automatically light up and illuminate the ground around the vehicle, which not only provides convenience but also increases certain safety and aesthetics. Common car welcome lights include door side welcome lights, LED projection welcome lights, foot space lighting, roof welcome lights, and threshold welcome lights. The film in the welcome light has a pre-made pattern or logo on it, and the light source of the welcome light projects the pattern on the ground or wall, etc. Different films have different patterns, and different occasions require different films and different lens sizes. Existing car welcome lights, such as the Chinese utility model patent with document number CN219160211U and the name of achromatic projection welcome light, can only be used for one size of film and focusing lens. If the size needs to be changed, the welcome light can only be replaced as a whole, which is wasteful and costly, so the scope of application is narrow. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a car welcome lamp. An inner shell for mounting a film and a focusing lens is arranged inside an outer shell, a slot is arranged on the outer shell, and a clamping column for clamping into the slot is arranged on the inner shell. When the film of different size or different pattern needs to be replaced, only the inner shell needs to be taken out for corresponding replacement, thereby reducing costs and expanding the scope of application.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a car welcome light, comprising an outer shell, an inner shell inserted into the outer shell from one end thereof, an imaging lens assembly and a film arranged in the outer shell, and a condenser lens arranged in the inner shell, wherein the film is located between the imaging lens assembly and the condenser lens;

[0005] A card slot is provided along the end of the outer shell and extends through the outer end, and a card column for engaging with the card slot is provided at one end of the outer periphery of the inner shell.

[0006] In the utility model, the clamping groove includes an axial groove portion arranged along the axial direction of the shell and a transverse groove portion perpendicular to the axial groove portion, the transverse groove portion is connected to the inner end of the axial groove portion, and the clamping column can be clamped in the transverse groove portion.

[0007] Wherein, the end surface of the outer shell is fixedly connected with a fixing plate by screws, and a light source is arranged on a side of the fixing plate close to the inner shell.

[0008] Furthermore, a slope is provided on one side of the clamping column close to the fixing plate, and an extrusion piece is provided on the fixing plate corresponding to the axial groove portion, and the extrusion piece is used to extrude the slope so that the clamping column is pushed into the transverse groove portion.

[0009] Furthermore, when the clamping column is clamped in the transverse groove, the inner end surface of the inner shell is in compression contact with the inner cavity end surface of the outer shell.

[0010] In the utility model, the clamping column does not protrude from the outer peripheral side of the shell.

[0011] In the utility model, an imaging shell is detachably arranged at one end of the housing away from the condenser lens, and the imaging lens assembly is arranged in the imaging shell.

[0012] In the utility model, the imaging lens assembly includes a first biconvex lens, a second biconvex lens, and a convex-concave lens. The convex-concave lens is arranged between the first biconvex lens and the second biconvex lens. The first biconvex lens is located on the side of the convex-concave lens away from the focusing lens, and the concave surface of the convex-concave lens is close to the first biconvex lens.

[0013] The beneficial effects of the utility model are as follows: the utility model sets an inner shell for installing the film and the focusing lens in the outer shell, sets a card slot in the outer shell, and sets a card column for inserting into the card slot in the inner shell. When it is necessary to replace films of different sizes or different patterns, it is only necessary to take out the inner shell for corresponding replacement. Films of different sizes correspond to inner shell thicknesses of different sizes. When the film size is large, the inner shell size is thinner, thereby expanding the scope of application and improving the replacement speed. Using the same outer shell can reduce costs, one shell can be used for multiple purposes, and the reusability of components is higher. At the same time, by setting an extrusion piece and an inclined surface, there is no need to actively rotate the inner shell. When installing the fixing plate, the extrusion piece squeezes the inclined surface to push the card column to the horizontal groove of the L-shaped card slot to fix the inner shell, which is convenient and quick.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] Directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only used for reference to the directions of the drawings. The directional terms used are used to illustrate and understand the present invention, and are not used to limit the present invention.

[0021] The following is a preferred embodiment of an efficient quick drying oven provided by the utility model that can solve the above technical problems. Figure 1-Figure 4 As shown, a car welcome light comprises an outer shell 1, an inner shell 2 inserted into the outer shell 1 from one end thereof, an imaging lens assembly 4 and a film 8 arranged in the outer shell 1, and a focusing lens 7 arranged in the inner shell 2, wherein the film 8 is located between the imaging lens assembly 4 and the focusing lens 7.

[0022] A card slot 10 is provided along the end of the outer shell 1 and extends outward, and a card column 11 for engaging with the card slot 10 is provided at one end of the outer periphery of the inner shell 2 .

[0023] An imaging housing 3 is detachably provided at one end of the housing 1 away from the focusing lens 7, and the detachable connection may be a threaded connection, and an imaging lens assembly 4 is provided inside the imaging housing 3. The imaging lens assembly 4 includes a first biconvex lens, a second biconvex lens, and a convexoconcave lens, the convexoconcave lens is provided between the first biconvex lens and the second biconvex lens, the first biconvex lens is located on the side of the convexoconcave lens away from the focusing lens 7, and the concave surface of the convexoconcave lens is close to the first biconvex lens.

[0024] The card slot 10 is L-shaped, and includes an axial slot portion arranged along the axial direction of the housing and a transverse slot portion perpendicular to the axial slot portion. The transverse slot portion is connected to the inner end of the axial slot portion, and the card column 11 can be clamped in the transverse slot portion.

[0025] The end surface of the outer shell 1 is fixedly connected with a fixing plate 5 by screws. A threaded hole can be arranged on the end surface of the outer shell 1 . A light source 6 is arranged on one side of the fixing plate 5 close to the inner shell 2 .

[0026] A slope 13 is provided on one side of the clamping column 11 close to the fixing plate 5, and an extrusion piece 12 is provided on the fixing plate 5 corresponding to the axial groove. The extrusion piece 12 is used to extrude the slope 13 so that the clamping column 11 is pushed into the transverse groove, so that when the fixing plate 5 is installed, the connection between the outer shell 1 and the inner shell 2 can be further secured.

[0027] The maximum width of the extrusion piece 12 is smaller than the minimum width of the axial groove portion of the clamping groove 10 , and the end of the extrusion piece 12 used for extruding the inclined surface 13 is hemispherical.

[0028] When the clamping column 11 is clamped in the transverse groove, the inner end surface of the inner shell 2 is pressed into contact with the inner cavity end surface of the outer shell 1, so that the outer shell 1 and the inner shell 2 are firmly matched.

[0029] Preferably, the clamping column 11 does not protrude from the outer peripheral side of the housing 1 .

[0030] When it is necessary to replace the film 8 of a different size or a different pattern, it is only necessary to take out the inner shell 2 and replace it accordingly. Films 8 of different sizes correspond to the thickness of the inner shell 2 of different sizes. When the film size is large, the inner shell size is thinner, thereby expanding the scope of application and improving the replacement speed. Using the same outer shell 1 can reduce costs, use one shell for multiple purposes, and increase the reusability of components.

[0031] At the same time, by setting the extrusion piece 12 and the inclined surface 13, there is no need to actively rotate the inner shell 2. When installing the fixing plate 5, the extrusion piece 12 squeezes the inclined surface 13 to push the clamping column to the horizontal groove portion of the L-shaped clamping groove 10 to fix the inner shell 2. The structure is simple and convenient.

[0032] Working principle: During installation, the column 11 of the inner shell 2 corresponds to the slot 10, and then the inner shell 2 is inserted into the outer shell 1; you can choose to directly rotate the inner shell 2 to turn the column 11 into the transverse groove of the slot 10, or you can choose not to actively rotate the inner shell 2. At this time, align the extrusion piece 12 on the fixed plate 5 with the axial groove of the slot 10, and then insert it into it. When the extrusion piece 12 is inserted, the end of the extrusion piece 12 abuts against the inclined surface 13. As the extrusion piece 12 is continuously inserted, the column 11 is pushed to move in the transverse groove due to the existence of the inclined surface, and moves toward the end of the transverse groove away from the axial groove until the fixed plate 5 fits with the end face of the outer shell 1, and finally the fixed plate 5 is fixed to the outer shell 1 with screws.

[0033] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
