Description

  The present invention relates to an accessory case in a vehicle, and more particularly to a technique of a holder that accommodates a remote control switch for operating a vehicle air suspension.

In recent years, trucks equipped with air suspensions have become popular in order to prevent damage to cargo due to vibration.
The air suspension system is capable of handling a large change in loading capacity, so that the rear part of the loading platform can be used for adjusting the vehicle height when unloading and unloading for cargo trucks, or a coupler for tractors. A remote controller for adjusting the height is installed.
Further, in order to adjust the vehicle height of the air suspension from the passenger compartment without getting off the vehicle, the remote controller, or a wired or wireless remote controller different from the above, is attached to the switch holder (case) installed in the passenger compartment. The remote controller may be stored and operated as necessary.

On the other hand, recent trucks are equipped with various equipment, and there is often no room for a dedicated switch holder or the like around the driver's seat.
When there is no room for such a dedicated holder, as shown in FIG. 5, for example, a mounting hole (not shown) is provided in the wall surface of the console 100, and the holder B (partial sectional view in FIG. 5, perspective view in FIG. 6). May be attached to the wall surface of the console 100 via an attachment member.
However, when the mounting member is a bolt / nut, the nut cannot be fixed unless a tool is inserted into the back side of the console during installation. That is, blind work is performed.
In order to avoid such inconvenience, conventionally, a resin clip C as shown in FIG. 5 has been used.

The resin clip C has extremely low strength compared to steel bolts and nuts.
Further, the mounting surface B33 of the holder B is small as shown in FIG. 5, and when the mass W of the remote controller R acts at a position where the horizontal distance from the mounting surface B33 is L as shown in the drawing, the mounting surface B33 Around the lower end P1 point, a moment W × L acts clockwise, while at the center of the clip C, a moment F1 × L1 acts. Here, F1 is a force that prevents the clip from being pulled out, and L1 is a linear distance from the axis of the clip to the point P.
The magnitude of F1 will be discussed as a comparison at similar positions in the embodiments of the invention described below.
Note that the holder (of the prior art) has the same structure, configuration, and name of each part as those of the embodiments of the present invention described later, except that no rib is formed on the lower surface of the attachment part B3. A description thereof is omitted here.

  When the mounting seat surface B33 is small as shown in FIG. 5 (the value of L1 is small), the force for pulling out the clip C (the force having the same absolute value as F1 but in the opposite direction) becomes large (for the reason of the embodiment). As will be described later in the description), especially when such a force is repeatedly applied, the clip C may be broken.

As another conventional technique, a pager holder for fixing a pager in a vehicle is provided (see, for example, Patent Document 1).
However, such a pager holder is intended to improve the reception rate reduction of the pager in the vehicle, and does not solve the above-described problems.
JP 2002-16954 A

  The present invention has been proposed in view of the above-described problems of the prior art, and when a stored item is stored in the holder, the mass of the vehicle height adjustment switch (remote control switch), which is the stored item, acts on the holder. Even so, an object of the present invention is to provide a switch holder that avoids a large pulling force from acting on a resin clip as a mounting member.

  According to the present invention, in the vehicle height adjustment switch holder (A) which is attached to the vertical wall surface of the console (100) of the truck, and which accommodates the remote control switch (R) for adjusting the vehicle height by the air suspension, A pocket portion (1) for accommodating the remote control switch (R) is formed as a rectangular parallelepiped space by a bottom portion (11), a front surface portion (12), a back surface portion (13), and a side portion (14). The part (13) is formed with an oval attachment part (3) that is recessed in the direction away from the front part (12) at substantially the center thereof, and the rear surface of the attachment part (3) is connected to the console (100). A plurality of attachment holes (35) are formed through which the resin clip (C) is inserted in contact with each other to form a main attachment surface (33), and below the back surface portion (13) and the attachment portion (3) A plurality of pull-out force relaxation ribs (4) are provided in a region surrounded by the flat portion (31a) and the console (100) wall surface, and these ribs (4) extend downward from the lower horizontal portion (31a). It extends to the same surface (42) as the bottom portion (11) of the pocket portion (1) and extends rearward from the back surface portion (13) to become the same surface as the main attachment surface (33), which is the second attachment. The surface (41) is formed, and the distance (L1) from the clip mounting hole (35) to the mounting surface end (P1) is increased to the lower end (P) of the second mounting surface (41), and the clip is pulled out. It is a configuration that can reduce the force.

  According to the present invention having the above-described configuration, the remote control switch (R) for adjusting the vehicle height by the air suspension of the lorry is attached to the console (100) extending in the vertical direction by the resin clip (C). The pocket (1) to be accommodated and the resin clip (C) are inserted into the console (100) while being spaced apart from the vertical wall surface (13) constituting the pocket (1). A main mounting surface (33) to be mounted in C) and a second mounting surface (41) on the extension of the main mounting surface (33), and a pulling force alleviating mechanism that alleviates the pulling force acting on the resin clip (C) (Pull-out force relaxation rib 4), and the pull-out force relaxation mechanism (pull-out force relaxation rib 4) is between the main mounting surface (33) and the vertical surface (13) constituting the pocket. A plurality of rib-shaped members (drawing force relaxation ribs 4) formed in the region, and a lower end (42) of the second mounting surface of the rib-shaped member (pulling force relaxation ribs 4) is formed on the pocket portion. Since it extends to the vicinity of the lower end (bottom part 11), the pulling force acting on the resin clip (C) is reduced by the extent that the mounting surface is extended by the rib-shaped member (pulling force relaxation rib 4).

  The pull-out force relaxation rib (4) requires only a small amount of material compared to before the rib (4) is added. That is, the effect is tremendous with respect to the amount required for the countermeasure.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 is a front view of a vehicle height adjusting switch holder A according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. 3 is a perspective view of the holder as viewed from the back, that is, from the mounting surface side. FIG.
FIG. 4 is a cross-sectional view for explaining the force acting on the mounting clip (resin clip C) when the vehicle height adjustment switch (remote controller) R is housed in the holder A.

  1 and 2, the vehicle height adjusting switch holder has a pocket portion 1 and a mounting portion 3 for accommodating a remote control switch R for adjusting the vehicle height (in FIG. 2, the contour is shown by a two-dot chain line). is doing.

  The pocket portion 1 is formed in a rectangular parallelepiped space by a bottom portion 11, a front surface portion 12, a part of the back surface portion 13, and a side portion 14.

  The front surface portion 12 is configured to be lower than the back surface portion 13.

The back surface portion 13 is formed with an oval concave portion at a substantially center in a direction away from the front surface portion 12, and the entire oval concave portion is configured as the attachment portion 3.
That is, the attachment part 3 includes an elliptical upper and lower horizontal parts 31, 31, arcuate parts 32, 32 connecting the upper and lower horizontal parts 31, 31, and a main attachment surface 33 that is the entire attachment surface on the back surface. It is composed of

  On the main attachment surface 33, at two locations in the vicinity of the arc portion 32, resin clips (not shown) which are attachment members (see FIG. 4 described later) are inserted, and attachment holes 35 for attaching the holder A are formed. .

  The outer peripheral rib 2 is formed in a direction perpendicular to the back surface portion 13 in the region excluding the lower side in the outline of the back surface portion 13. The outer peripheral rib 2 is formed such that an upper surface rib 21 and side ribs 22 on both side surfaces are continuously formed integrally, and in particular, the side rib 22 is continuous with the side portion 14 of the pocket portion 1 as one plane (FIG. 3). See).

  The position of the rear end (left end in the figure) of the rib 2 is configured to be located on the extended surface of the main mounting surface 33.

Pulling force relaxation for abutting the lower horizontal surface portion 31a of the mounting portion 3 and the back surface portion 13 of the pocket portion 1, and for reducing the pulling force of the clip at three locations in the illustrated example toward the lower side of the horizontal portion 31. Ribs 4 are formed.
The rear end (second mounting surface in claim 1) 41 of the pulling force relaxation rib 4 is formed so as to be flush with the main mounting surface 33 of the mounting portion 3, and the lower end 42 of the pulling force relaxation rib 4. Is formed so as to be flush with the bottom 11 of the pocket portion 1.

  FIG. 4 shows a state in which the holder is fixed to a vertical wall surface of the console 100 using a resin clip C, for example.

At this time, a remote controller R for adjusting the vehicle height is accommodated in the pocket portion 1 of the holder A, and the rear end 41 of the pulling force reducing rib 4 is caused by the mass W of the remote controller R for adjusting the vehicle height. In addition, a rotational moment M1 for pulling out the resin clip C acts around the corner P of the lower end 42. If the horizontal distance from the corner P to the center of gravity Gc of the remote controller R is L, the magnitude of the moment M1 is
M1 = L · W.

On the other hand, a force F2 against the pulling force is generated in the resin clip C, and a resistance moment M2 around the corner P is generated by the force F2 against the pulling force. This resistance moment M2 and the moment to be pulled out are generated. The holder is kept fixed to the wall surface 100 by equalizing M1.
Here, if the linear distance from the central axis of the resin clip C to the corner P is L2,
M2 = L2 ・ F2
Since M1 = M2,
L2 · F2 = L · W.
That is, it is expressed as F2 = L · W / L2.

On the other hand, in the conventional type switch holder B in which the above-described pulling force relaxation rib 4 is not provided, again referring to FIG.
L1 · F1 = L · W,
F1 = L · W / L1 is easily derived.

When the force F2 that resists the pulling force in the switch holder A of the embodiment of the present invention and the force F1 that resists the pulling force in the conventional type switch holder B that does not have the pulling force relaxation rib 4 are compared, L · W Since F2 having a long offset amount L2 is naturally smaller, the pulling force acting on the clip C is also small.
That is, the pulling force decreases in proportion to the offset amounts L2 and L1.
If L2 is set to be three times as large as L1, the pulling force acting on the clip C can be reduced to one third.

  The pull-out force relaxation rib 4 requires only a small amount of material compared to before the rib 4 is added. That is, the effect is tremendous with respect to the amount required for problem countermeasures.

  It should be noted that the illustrated embodiment is merely an example, and is not a description of the purpose of limiting the technical scope of the present invention.
