Description

  The present invention relates to an attachment structure for detachably attaching an in-vehicle speaker to an attachment opening of a vehicle side panel.

  Conventionally, as a method of attaching a speaker, particularly a vehicle-mounted speaker to a panel inside a vehicle, in addition to a fastening method using screws and mounting brackets as has been done for a long time, it has been used in a speaker that has been frequently used recently. There is a so-called one-touch system in which the elastic locking clip is elastically locked to the locking portion on the panel side.

  As an example of the one-touch method, the mounting structure described in Utility Model Registration No. 2593939 is an elastic locking clip that stands upright on the back side of the speaker along the outer periphery of the frame on one side of the diameter direction of the speaker frame, and the outer periphery of the frame on the other side. An insertion hook projecting in the radial direction is provided, and the elastic locking clip is shaped like a leaf spring having a V-shaped or W-shaped cross section, and its extended portion is elastically locked to the back side of the locking portion of the panel. When attaching the speaker, insert the insertion hook into the engagement hole adjacent to the speaker attachment opening on the panel, and insert the back side of the speaker into the speaker attachment opening. It is elastically fitted to the notch and locked to the back side of the panel. In this locked state, a screw or the like is inserted and fixed as a return preventing member into the V or W-shaped extended portion of the elastic locking clip.

  In utility model registration No. 2603923, which shows another example of the one-touch method, the elastic locking clip has a concave cross section in order to compensate for the lack of strength of the elastic locking clip standing upright on the back side on the outer periphery of the speaker frame. The positioning member is integrally formed with the inner portion of the positioning member, and the portion other than the elastic locking surface is surrounded by the positioning member. For attachment to the vehicle side panel, a plurality of attachment structures with elastic locking clips reinforced in such a configuration are used, or in combination with an insertion hook that is upright and elastic like the clip.

In the mounting structure disclosed in Japanese Patent Laid-Open No. 2001-352590, in which another example of the one-touch method is shown, in order to provide a waterproof structure between the mounting panel and the speaker frame, the panel mounting opening is surrounded by an annular shape between the two. The elastic locking clip and the insertion hook are arranged inside the outer peripheral edge of the sealing member. At the same time, in order to make the speaker detachable from the mounting panel and make it detachable, a tool insertion recess is provided on the outer periphery of the speaker frame or a part of the corresponding panel, and a recess is provided in a part of the corresponding seal member, It is possible to release a lock by inserting a tool such as a flathead screwdriver from the outside of the speaker and pushing an elastic lock clip.

  As described above, the one-touch method uses an insertion hook when it is hooked on the panel and then elastically locks, compared to the known screw or mounting bracket method, which requires a screw tightening operation. Since the attaching operation is completed by simply pushing the clip into the panel locking hole or the like, the productivity is remarkably improved. However, in Patent Document 1, there is a risk that the elastic locking clip is returned by gravity of the speaker itself against the elasticity due to a strong vibration action or the like, and the locking is released. In this document, as a measure other than the use of the anti-return material, it is necessary to increase the elasticity of the elastic locking clips or increase the number of clips, but this reduces the workability and the cost problem. There is a problem that it occurs.

  Patent Document 2 shows an example in which the positioning member surrounding the clip limits the return of the clip while improving the strength of the elastic locking clip. However, the waterproofness and the detachability shown in Patent Document 3 are completely suggested. Not.

  On the other hand, Patent Document 3 relates to waterproofing, a seal member is formed with a recess corresponding to a tool insertion recess for pushing back the clip, and a slight gap is formed between the recess and the panel. In addition, there is no fear of inflow of water from this gap, and since the speaker has a waterproof structure, it is assumed that some wetting does not hinder, and the waterproof is not perfect. Furthermore, tool insertion is performed while compressing the seal member, which may cause damage to the seal member. In any case, in the configuration shown in Patent Document 3, in order to obtain detachability in the vicinity of the elastic locking clip, even a little waterproofing must be sacrificed, that is, while ensuring high productivity. It is difficult to realize a speaker mounting structure that can achieve both waterproofness and detachability.

  The present invention has been proposed in view of the above, and the object of the present invention is to maintain high productivity by using a one-touch method with an elastic locking clip, and also to achieve overall waterproofness including the vicinity of the elastic locking clip. It is another object of the present invention to provide a speaker mounting structure that can be compatible with both detachability and easy release of the locked state without impairing waterproofness.
