Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for small automobile parts.

The conventional mounting structure for small automotive parts is as follows:
There are parts as shown in Figure 1 (top view) and parts as shown in Figure 2 (top view), in which small automotive parts a are attached to bolts c via mounting brackets b or band b'. It is attached to the support plate d by a nut c'.

However, with such a conventional mounting structure, if the small part a needs to be replaced frequently or periodically, the replacement work requires a considerable amount of time, and the number of parts is large, making it expensive from a cost standpoint. There is a problem with becoming.

The present invention attempts to solve these problems by making it possible to install and remove small automotive parts with a single touch, securely fix the position, and reduce costs. The purpose of the present invention is to provide a mounting structure for small automobile parts that can be mounted on the vehicle.

Therefore, in the mounting structure of the small automotive parts of the present invention, a groove into which the support plate is inserted is formed on the outer surface of the small automotive part, and a pair of engaging parts protrudes from the edge of the groove onto the groove. The locking claws are formed to face each other, and each of the locking claws has an engaging protrusion that projects into the groove and is tapered at both ends in the insertion direction of the support plate. The support plate is characterized in that a concave portion is formed in the support plate to engage and surround both the engagement protrusions when the plate is inserted.

Hereinafter, a mounting structure for small automobile parts as an embodiment of the present invention will be explained with reference to the drawings.
Fig. 3 is a front view of the same, Fig. 4 is an exploded perspective view for explaining how to attach the small automobile parts to the support plate, Fig. 5 is a cross-sectional view showing the main parts thereof, and Fig. 6 The figure is an enlarged sectional view taken along the - arrow in FIG.

As shown in FIGS. 3 to 6, an outer surface 1a of a canister 1 as a small automobile part made of synthetic resin.
A pedestal 2 is formed integrally with the pedestal 2, and a groove 6 of a constant depth is formed in the pedestal 2, into which a support plate 5 with a vehicle body is inserted.

A pair of locking claws 3, 3 projecting from upper and lower edges 2a, 2b of the groove 6 formed in the base 2 onto the groove 6 and parallel to the base 2 are formed to face each other.

Further, at the tips of each of the mutually opposing locking claws 3, 3, an engaging protrusion 4 protruding into the groove 6 is formed so as to have a tapered part 4a at both ends thereof.

Further, on the surface of the support plate 5 inserted into the groove 6, an opening-shaped recess 5a serving as an engagement portion capable of engaging with the engagement protrusion 4 and a stepped portion 5b that comes into contact with the locking claw 3 are formed. In addition, a tapered portion 5c is formed that rises and slopes from the surface of the support plate 5 to the step portion 5b.

The shape of the recessed portion 5a is the same as that of the engaging protrusions 4, 4.
The height of the stepped portion 5b is slightly higher than the depth of the groove 6 between the base 2 and the locking pawl 3. There is. Note that the reference numeral 3' in FIG. 5 indicates a deformed locking pawl.

Since the mounting structure of the present invention for attaching small automotive parts is configured as described above, when attaching the canister 1 to the support plate 5, first, the groove portion 6 is opposed to the tip of the support plate 5, and the canister 1 is attached to the support plate 5. 4 Push in the direction of the arrow shown in Figure 4.

At this time, the tapered part 4a of the engagement protrusion 4 slides on the tapered part 5c of the support plate 5, and the locking pawl 3 is easily deformed to the state shown by reference numeral 3'. Become. (See the dashed line in FIG. 5) When the canister 1 is further pushed in, the engagement protrusion 4 and the concave portion 5a of the support plate 5 engage with each other.
This engagement is an engagement in which the engagement protrusion 4 is surrounded by the concave portion 5a, in other words, an engagement in which the engagement protrusion 4 and the concave portion 5a mesh (see FIG. 6). is attached to the support plate 5 with one touch and is securely held in that position. Furthermore, since the locking pawl 3' deformed at this time comes into contact with the surface of the stepped portion 5b due to the elastic restoring force, the canister 1 can be reliably attached to the support plate 5 without fear of swinging.

On the other hand, when removing the canister 1 from the support plate 5, the pair of locking claws 3, 3 are bent using a desired jig (for example, a flat head screwdriver), and then the canister 1 is attached to the support plate 5. You can remove it by following the steps in reverse. Thereby, it can be easily removed without damaging the engaging protrusion 4 or the like.

This structure is applied not only to the mounting structure of a canister but also to the mounting structure of fuel check valves and other small parts for automobiles.

As described above in detail, according to the mounting structure for small automotive parts of the present invention, a groove into which the support plate is inserted is formed on the outer surface of the small automotive part, and the groove is extended from the edge of the groove to the top of the groove. A pair of locking pawls extending outward from each other are formed to face each other, and each of the locking pawls has an engaging protrusion at its tip that projects into the groove and is tapered at both ends in the insertion direction of the support plate. With a simple structure in which a concave portion is formed in the support plate to engage and surround both of the engagement protrusions when the support plate is inserted, attachment and detachment of small automobile parts is possible. This can be done with one touch, and the position can be fixed reliably.Furthermore, there is no possibility of small objects swinging after they are attached, and the simple structure with a small number of parts also reduces costs. In addition, since the engaging protrusion is engaged with and surrounded by the recessed part, there is an advantage that the engaging protrusion does not come into contact with the operator's hand after installation, and is less likely to be damaged.
