Furthermore, we will not explain the switches on the front operation panel and the cables on the rear side of the exterior of the in-vehicle radio.

(Explanation of configuration)
FIG. 1 shows an assembly of an in-vehicle radio 101 having an electronic device mounting structure according to an embodiment of the present invention, a mounting bracket 102 (holding frame), and a fixture for fixing an electronic device (hereinafter simply referred to as a fixture) 103. FIG. 3 is a perspective view showing the external appearance. The chassis 101a, that is, the housing of the vehicle-mounted radio device 101 has a substantially rectangular external appearance. The mounting bracket 102 is a member that is fixed to a structure (not shown) and supports the vehicle radio device 101 by sandwiching the chassis 101a from the left and right sides. The fixing bracket 103 is a member that is sandwiched between the chassis 101a and the mounting bracket 102 near the front side of the vehicle-mounted radio device 101, and fixes the vehicle-mounted radio device 101 to the mounting bracket 102.

[Mounting bracket]
The mounting bracket 102 is a metal plate having a generally U-shaped cross section and has parallel left and right walls sandwiching the chassis 101a from the left and right sides. As shown in FIG. 2, the mounting bracket 102 includes a mounting bracket main body 102a having a U-shaped cross section, a limiter LT at the back end of the left and right walls, and a pair of parallel insertion guide portions at the tips of the left and right walls. 102a-1, a bracket 102b joined to the front left wall of the mounting bracket main body 102a with two rivets 102c, and a mounting hole 102b-1 provided in the bracket 102b near the rivet 102c.

The limiter LT of the mounting bracket 102 is a stop portion that restricts the movement of the in-vehicle radio 101 so that it does not come off from the rear side.

The pair of left and right insertion guide portions 102a-1 have leading edge portions facing each other in parallel and fitting into left and right insertion guide grooves 101a-2 (described later) of the in-vehicle radio 101.

The bracket 102b is a cantilever made of an elastic (springy) sheet metal body. The bracket 102b has an insertion guide shape 102b-2 at its tip. By pressing the insertion guide shape 102b-2 at the tip of the bracket 102b to the left, the bracket 102b is elastically deformed. The bracket 102b is a locking portion whose mounting hole 102b-1 fits into a fixture 103 (described later). The bracket 102b presses the fixing fitting 103 in the right direction toward the in-vehicle radio 101 when inserted.

Further, a pair of cushions 102d are arranged at both left and right corners inside the mounting bracket main body 102a, facing the insertion guide portion 102a-1. The cushion 102d is a buffer member that maintains the position of the vehicle radio 101 in the insertion/extraction direction by applying a load due to the elasticity of the cushion 102d when the vehicle radio 101 is fitted into the mounting bracket 102.

Further, FIG. 1 shows a case where an in-vehicle radio device 101 is fixed to the top surface of a structure (not shown) via a mounting bracket 102. The mounting bracket 102 can be opened upward to hold the in-vehicle wireless device 101 from below, or can be opened downward to suspend and hold the in-vehicle wireless device 101 from above.

As shown in FIG. 3, two pairs of parallel insertion guide grooves 101a-2 are provided on the left and right sides of the chassis 101a of the vehicle-mounted radio device 101, extending from the back side to the front side and symmetrical about the left and right sides. When the insertion guide groove 101a-2 fits with the tip edge of the insertion guide portion 102a-1 of the mounting bracket 102, the vehicle radio 101 is supported by the chassis 101a. The reason why the two pairs of parallel insertion guide grooves 101a-2 are provided is to select whether to hold the in-vehicle radio 101 upward or downward, regardless of whether the mounting bracket 102 is opened upward or downward. be.

Further, on the left and right sides of the chassis 101a of the vehicle-mounted radio device 101, a rectangular recess RC for positioning the fixing metal fitting 103 is provided on the front side following the insertion guide portion 102a-1. Two pairs of left and right female screw portions 101a-1 for fastening to the fixing fitting 103 are provided on the bottom surface of the recess RC. The recessed portion RC has an inner surface IF that is parallel to the insertion guide portion 102a-1 that also functions as a guide groove for a part of the fixing metal fitting 103.

The reason why the recess RC with the female screw part 101a-1 and the bracket 102b with the mounting hole 102b-1 of the mounting bracket 102 are arranged on the front side of the left side of the in-vehicle radio 101 is that This is to allow maintenance to be performed adjacent to the operation surface in the same direction. Although the fixing metal fitting 103 is disposed on the front side of the left side of the vehicle-mounted radio 101 here, it may be disposed on the right side.

[securing bracket]
As shown in FIG. 4, the fixing metal fitting 103 includes a first fixing metal plate 103b on the fixed side (a screw holding part capable of holding a screw along one axis) which is fixed with a countersunk screw 103c, and a screw holding part that can hold a screw along one axis. It includes a movable second fixture plate 103d (latch part) and a torque stamper screw 103e that connects the two. As shown in FIG. 5, by fastening (screwing) the torque stamper screw 103e, the first fixture plate 103b and the movable second fixture plate 103d are slid together and configured to be fixed. The torque stamper screw 103e is a screw that is turned using a special screwdriver that matches the driving part of the screw head. Although the torque stamper screw 103e is used as the tamper-proof screw, other special screws may be used.

The first fixing metal plate 103b on the fixed side is approximately L-shaped, and has a bent portion BP that fits into a recess RC on the side surface of the vehicle radio 101 on the back side, and a seat surface SF for a torque stamper screw on the front side. It is a sheet metal body. The seat surface SF is formed to be perpendicular to the side surface of the vehicle-mounted radio 101 when the first fixing plate 103b is fixed to the side surface, and further has a female screw hole FH for a torque stamper screw. The axis of the torque stamper screw to be screwed in is parallel to the side surface and the insertion guide groove 101a-2.

The seating surface SF of the first fixing plate 103b has a protective part around the screw head of the torque stamper screw that protrudes forward across the female threaded hole FH for the torque stamper screw to prevent contact with the screw. Bending L103b-1 and bending R103b-2, which are wall portions, are formed in parallel. The bend L103b-1 and the bend R103b-2 are arranged in the vicinity of the female threaded hole FH so as to prevent the left and right chucking of the screw head of the torque stamper screw 103e. The walls of the protection part may be provided not only parallel but also at right angles to each other. Note that a through hole PH for a countersunk screw is formed in advance between the seating surface SF and the bent portion BP of the first fixture plate 103b.

[Second fixture plate]
The second fixture plate 103d on the movable side is a roughly L-shaped metal plate like the first fixture plate 103b on the stationary side, and its seat surface SF2 has a torque stamper screw plate. It has a female screw hole FH2. The second fixture plate 103d is coupled to the first fixture plate 103b by torque stamper screws screwed into both female screw holes FH and FH2, and is also slid onto the first fixture plate 103b. It is formed so that That is, the second fixture plate 103d is configured to be movable (slide) relative to the first fixture plate 103b by rotation of the torque stamper screw 103e.

The second fixing plate 103d has a bent hook portion that fits into the mounting hole 102b-1 (FIG. 2) of the bracket 102b and locks when the first fixing plate 103b is fixed to the side surface of the in-vehicle radio 101. 103d-1 (protrusion) and a guide shape 103d-2 that maintains the posture when the second fixture plate 103d slides. The bending hook portion 103d-1 has a height that projects beyond the bracket 102b in a direction intersecting the movable direction.

The tip of the bending hook portion 103d-1 receives pressure from the bracket 102b when the second fixture plate 103d slides.

The bending hook portion 103d-1 has a hook portion PJ projecting forward at its tip. The hook PJ enters the mounting hole 102b-1 of the bracket 102b when the first fixing plate 103b is fixed to the side surface of the vehicle radio 101, and then the second fixing plate 103d is driven. It is formed so as to be engaged with and fixed to the bracket 102b.

The guide shape 103d-2 has an inner surface IF parallel to the insertion guide portion 102a-1 of the recess RC on the side surface of the vehicle radio 101 when the first fixing plate 103b is fixed to the side surface of the vehicle radio 101. It is formed so that it is guided by.

(Explanation of operation)
[Attachment of fixing bracket 103 to in-vehicle radio]
As shown in FIG. 6, the first fixing plate 103b is fixed to the female threaded portion 101a-1 of the in-vehicle radio 101 with a countersunk screw 103c through a countersunk screw through hole PH. The spacer 103a is sandwiched between the first fixing plate 103b and the recess RC on the side surface of the in-vehicle radio 101, and then fixed with flat head screws 103c.

As shown in FIG. 7, the first fixing plate 103b on the fixed side is fixed to the front side of the insertion guide section 102a-1.

As shown in FIG. 8, the second fixing plate 103d is superimposed on the first fixing plate 103b fixed to the side surface of the in-vehicle radio 101, and the first fixing plate 103b and the second Align both female screw holes FH and FH2 of the fixing plate 103d, and screw the torque stamper screw 103e into these screw holes from the front side (operation surface side) of the in-vehicle radio 101, as shown in FIG. 9, to secure the second fixation. With the metal fitting plate 103d in the unlocked state (a state in which the hook portion PJ of the bending hook portion 103d-1 can pass through the mounting hole 102b-1 when the in-vehicle radio 101 is inserted up to the limiter LT on the back side), the first fixation is performed. It is held on the metal plate 103b.

In this way, the fixing metal fitting 103 is attached to the left side surface of the in-vehicle radio 101.

[Insertion of in-vehicle radio into mounting bracket 102]
As shown in FIG. 10, the in-vehicle radio 101 with the fixing bracket 103 attached to the left side is attached to the fixing bracket 103 from inside the bracket 102b of the mounting bracket 102 attached to a structure (not shown) such as a vehicle. Insert the brackets 102b so that they are aligned and close to each other.

As shown in FIG. 11, the in-vehicle radio 101 is attached to the mounting bracket 102 while the bent hook portion 103d-1 of the second fixing bracket plate 103d is inserted into the mounting hole 102b-1 of the bracket 102b by protruding from the inside. Insert it until it reaches the limiter LT (Fig. 1) on the far side.

In this way, as shown in FIG. 12, the in-vehicle radio 101 is inserted up to the limiter LT of the mounting bracket 102 with the fixing bracket 103 in the unlocked state.

[Fixing and releasing the in-vehicle radio to the mounting bracket 102]
With the fixture 103 in the unlocked state, the first fixture plate 103b and the second fixture plate 103d are fitted and fastened using the torque stamper screw 103e from the insertion direction of the vehicle-mounted radio 101. This screw tightening is carried out using a special screwdriver that matches the drive part of the screw head of the torque stamper screw 103e.

As shown in FIG. 13, by fastening (tightening) the screws, the second fixture plate 103d slides along the inner surface IF (FIG. 6) of the recess RC of the in-vehicle radio 101 and is pulled forward. The hook portion PJ of the bending hook portion 103d-1 presses the outer side of the plate thickness surface of the bracket 102b and is engaged with the bracket 102b, thereby fixing the in-vehicle radio device 101.

In this way, since the bracket 102b is a sheet metal having elasticity, the fixing metal fittings 103 (first fixing plate 103b and second fixing plate 103d) and torque stamper screws 103e are attached to the in-vehicle radio 101 side in advance. By doing so, the bracket 102b is bent so that the bending hook portion 103d-1 pushes up along the guide shape 102b-2 of the bracket 102b (FIG. 11), and the bracket 102b is inserted into the mounting hole 102b-1 position, and the torque stamper screw 103e is inserted. By tightening, the bending hook portion 103d-1 presses the outer side of the plate thickness surface of the bracket 102b and is caught and fitted, so that the in-vehicle radio 101 cannot be removed and is fixed and locked.

To remove the in-vehicle radio 101, loosen the torque stamper screw 103e, and move the bracket 102b out to the left in the unlocked position (Fig. 12) where the bent hook part 103d-1 is released from the attachment hole 102b-1. The in-vehicle wireless device 101 can be pulled out by bending it by hand.

(Explanation of effects)
As described above, according to this embodiment, there are bends L103b-1 and R103b-2, which are guard shapes that prevent the torque stamper screw 103e from being directly touched even if an attempt is made to chuck the torque stamper screw 103e with pliers. Unless deformation, damage, or destruction occurs, an effect that cannot be removed with a general tool other than a special tool suitable for the drive part of the screw head of the torque stamper screw 103e can be obtained.

Furthermore, since the torque stamper screw 103e is placed adjacent to the operation surface of the vehicle-mounted radio 101, it can be accessed from the same direction as the operation and maintenance surface, reducing restrictions on the mounting position of the vehicle-mounted radio 101, and saving space. This provides the effect of securing an installation work area.

In this embodiment, an example in which the present invention is applied to the in-vehicle wireless device 101 has been described, but the present invention can also be applied to other electronic devices that require anti-theft properties in a compact maintenance area with a locking structure that is inserted and fitted to prevent the device from coming off.

Further, according to this embodiment, by adding the fixing metal fitting 103, the bracket 102b, etc., it is possible to expect the effect of suppressing an increase in the number of parts and reducing the number of installation steps.

(Explanation of modified example)
The present embodiment described above is configured as shown in the schematic explanatory diagrams shown in FIG. 14 (FIGS. 14(a) to 14(c)), but the modified examples shown in FIGS. 14(d) to 14(f) are also included in the present invention.

In this embodiment, as shown in FIG. 14(a), the bending hook portion 103d-1 of the second fixture plate 103d in the unlocked state is protruded from the inside into the mounting hole 102b-1 of the elastically deformable bracket 102b. As shown in FIG. 14(b), insert the in-vehicle radio 101 to the limiter LT of the mounting bracket 102 with the fixing bracket 103 in the unlocked state, and then tighten the torque stamper screw as shown in FIG. 14(c). Although the structure is such that the first fixture plate 103b and the second fixture plate 103d are fitted and fastened together at 103e, in a modified example, as shown in FIG. In place of the second fixing plate 103d, a fixed screw holding plate 103b1 and a movable latch link 103d1, which are fixed to the in-vehicle radio 101, are used as the fixing plate 103. The latch link portion 103d1 has one end E1 rotatably screwed onto the screw head side of the torque stamper screw 103e, and the other end E2 rotatably supported by the screw holding portion plate 103b1, and is rotated toward the rear side by fastening the screw. This is a link mechanism part in which the intermediate joint part JT moves toward the mounting hole 102b-1 of the mounting bracket 102.

In the modified example, as shown in FIG. 14(d), the fixing fitting 103 (screw holding part plate 103b1 and movable side latch link part 103d1) is inserted between the mounting fitting 102 and the vehicle-mounted radio 101 in an unlocked state, As shown in FIG. 14(e), insert the in-vehicle radio 101 up to the limiter LT of the mounting bracket 102 with the fixing bracket 103 in the unlocked state, and then tighten the torque stamper screw 103e as shown in FIG. 14(f). The first fixture plate 103b and the second fixture plate 103d are fitted and fastened.

Furthermore, according to this modification, the fixing metal fitting 103 and the bracket can be omitted and the mounting hole 102b-1 is also provided in the mounting metal fitting 102, so that the effect of suppressing the increase in the number of parts and reducing the number of installation steps can be expected.
