[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 5-11207 Summary of the Invention [Problem to be solved by the invention]

[0004] However, according to the conventional vehicle lamps 11 and 12, since the method of removing the outer lens 2 is easy to understand, when the lamps are used on public vehicles, there is a risk that the outer lens 2 may be easily carried away by users of the vehicles. On the other hand, if the removal is made difficult, a problem arises in that it takes time and effort to replace the parts.

[0005] Therefore, an object of the present disclosure is to provide a vehicle lamp in which the method for removing the outer lens is not difficult to understand, and the outer lens is easy to attach and detach. [Means for solving the problem]

[0006] In order to solve the above problems, the vehicle lamp of the present disclosure has the following features. (1) A light source, a housing that accommodates the light source, and an outer lens that is removably attached to the housing, the outer lens including a lance extending toward the housing, the lance including a locking portion and a rib formed on the locking portion, the housing including a lockable portion that is locked by the locking portion, the lockable portion including a slit that receives the rib, and an opening is formed in the housing that communicates with the slit.

[0007] (2) In the case of (1) above, the rib may be configured to include an inclined surface that becomes higher from the base end to the tip end of the lance.

[0008] (3) In the case of (1) or (2) above, the housing can be configured to include an insertion hole through which the lance passes.

[0009] (4) In the case of (3) above, the locked portion can be provided on the periphery of the insertion hole.

[0010] (5) In any one of the above (1) to (4), the outer lens may include a plurality of lances extending toward the housing, and at least one of the plurality of lances may be provided with a rib. Effect of the Invention

[0011] According to the vehicle lamp of the present disclosure, since a rib is provided on the locking portion of the lance, the lance is difficult to bend, and it is difficult to understand how to remove the outer lens. On the other hand, since an opening is provided to expose the rib to the outside of the lamp, when the rib is pressed from the opening using a tool or the like, the lance bends, and the outer lens can be easily removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An embodiment of a vehicle lamp according to the present disclosure will now be described with reference to the drawings. In the following description, the outer lens 2 side is the front side of the lamp, and the housing 3 side is the rear side of the lamp.

[0014] The vehicle lamp 1 shown in Figs. 1 to 3 includes a light source (LED 4), a substrate 5 on which the LED 4 is mounted, a housing 3 that houses the LED 4 and the substrate 5, and an outer lens 2 that is detachably attached to the housing 3. A lamp chamber 6 is formed between the outer lens 2 and the housing 3. The housing 3 has a holder 7 that holds the substrate 5 in a predetermined position within the lamp chamber 6. The outer lens 2 and the housing 3 can be made of a resin material such as polycarbonate.

[0015] The housing 3 has an insertion hole 31 for inserting the lance 21, a locked portion 32 which is locked by the locking portion 22 of the lance 21, an opening 33 which communicates with the slit 32a of the locked portion 32, and a claw receiving portion 34 which receives the latching claw 24.

[0016] The housing 3 also has a shielding wall 35 that prevents direct light from the LED 4, i.e., light leakage from the gap between the outer lens 2 and the housing 3. In this example, the shielding wall 35 is formed so as to terminate at the periphery of the opening 33, but it is also possible to form the shielding wall 35 without interruption so as to surround the outer periphery of the opening 33.

[0017] The locked portion 32 has a slit 32a that receives the rib 23 of the lance 21. The opening 33 is opened so as to communicate with the slit 32a. Therefore, at least a part of the inclined surface 23a of the rib 23 is exposed from the opening 33 toward the outside of the lamp. The locked portion 32 is disposed on the periphery of the insertion hole 31.

[0018] The outer lens 2 has a plurality of lances 21, 21' extending toward the housing 3, and a latching claw 24 that is latched to the housing 3. The outer lens 2 can be composed of, for example, a light-transmitting base material 26 and a light-transmitting film 27. The base material 26 and the film 27 are preferably integrally molded by film insert molding. The film 27 is colored a predetermined color, for example, milky white, green, red, or the like. The light that has passed through the outer lens 2 illuminates the outside of the lamp in the color of the film 27.

[0019] 4 and 5, the lance 21 has a locking portion 22 that locks the locked portion 32 of the housing 3. The locking portion 22 has a first surface 22a that locks the locked portion 32 of the housing 3, and a second surface 22b that fits along the locked portion 32 (see FIG. 4(c)).

[0020] Of the multiple lances 21, 21', at least one lance 21 has a rib 23 formed on the locking portion 22. The rib 23 is formed to protrude from the second surface 22b at the widthwise center of the locking portion 22. In this example, the lances 21' are provided on both longitudinal sides of the vehicle lamp 1, and the lance 21 is provided at the longitudinal center.

[0021] By forming the rib 23, the locking portion 22 of the lance 21 becomes thicker at the widthwise center so as to protrude from the second surface 22b, and bending of the lance 21 in the direction to release the locked state (direction away from the locked portion 32) is suppressed. Therefore, as shown in Fig. 6(a), even if the side surface of the outer lens 2 is pressed, the lance 21 does not bend, and it is possible to prevent the outer lens 2 from being removed by bare hands.

[0022] Here, the rib 23 is formed with an inclined surface 23a that becomes higher (thicker) from the base end 21a to the tip end 21b of the lance 21. Therefore, when the tool T moves along the inclined surface 23a, a force is applied in the thickness direction of the lance 21, and the lance 21 can be bent in the unlocking direction. Therefore, as shown in Fig. 6(b), by inserting the tool T through the opening 33 and pushing the rib 23 toward the back of the lamp chamber 6, the locked state of the lance 21 can be easily released.

[0023] Next, a method for attaching and detaching the outer lens 2 using the tool T in the vehicle lamp 1 configured as above will be described with reference to FIG.

[0024] When attaching the outer lens 2 to the housing 3, the locking claws 24 of the outer lens 2 are hooked onto the claw receivers 34, and the lances 21 of the outer lens 2 are inserted into the insertion holes 31 while the locking portions 22 of the lances 21 are locked into the locked portions 32.

[0025] On the other hand, when removing the outer lens 2 from the housing 3, as shown in FIG. 7, a tool T is inserted into the opening 33 and pushed in so as to slide the tool T along the inclined surface 23a, whereby the lance 21 bends in the unlocking direction, and the locked state of the lance 21 can be released.

[0026] Therefore, according to the vehicle lamp 1 of this embodiment, since the rib 23 is formed on the locking portion 22 of the lance 21, it is possible to suppress bending of the lance 21 and prevent the outer lens 2 from being removed by bare hands. Also, by operating the rib 23 using a tool T through the opening 33, the outer lens 2 can be easily removed.

[0027] The present disclosure is not limited to the above-described embodiment, and the shape and configuration of each part can be appropriately modified without departing from the spirit of the present disclosure.

[0028] 3, the height h of the locked portion 32 of the housing 3 can be set to be higher (larger) than the protruding distance d from the first surface 22a of the rib 23. In this case, the rib 23 is disposed inside the lamp chamber 6 relative to the opening 33, making the rib 23 less noticeable from the outside of the lamp. [Explanation of symbols]
