Description

[Detailed Description of the Invention] The present invention relates to a mounting device for mounting an electronic device to a mounting bracket that is fixedly installed under the dash board of an automobile.

Conventionally, this type of mounting device has screw seats 2 on both sides of the front surface of an electronic device 1, as shown in FIG.
A known structure is known in which the mounting bracket 5 has a locking piece 6 with a screw hole at a position that matches the screw seat 2. The mounting bracket 5 is fixedly installed under the dash board of an automobile through the mounting hole 7 provided on its upper surface, and is mounted by engaging the guide groove 4 of the electronic device with the guide piece 8 of the mounting bracket. 3 fixes the electronic device 1. Since it is screwed in this way, tools such as a screwdriver are required when installing and removing electronic equipment, and it is difficult to work in the narrow space of a car, and it takes time to install and remove electronic equipment. Since it requires protruding parts such as screw seats, it does not look good, and it also has disadvantages such as not being able to handle cases where electronic equipment needs to be installed upside down depending on the mounting location of the mounting bracket, etc. It has a mounting structure.

The present invention is aimed at solving the above-mentioned drawbacks, and embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 2, 3, 4, and 5 are an exploded perspective view, a partial plan view, a partial sectional plan view, and a side view of the embodiment of the present invention in use. In the figure, a U-shaped metal fitting 13 having an open end at the front so as to cover a part of the outer surface of the fitting 12 is attached to the fitting 12 with a certain gap. A lock knob 17 having a protrusion 18 at approximately the center in the longitudinal direction and having an inclined tip is incorporated into a gap between the U-shaped fittings 13 together with a V-shaped leaf spring 22. The leaf spring 22 enters the concave surface 19 provided on the lock knob 17, and the circular protrusion 20 fits into the locking hole 23 of the leaf spring.
The plate spring 22 is fitted to prevent the leaf spring 22 from shifting. Also, the protrusion 18 of the lock knob 17
is adapted to fit into a slightly larger fulcrum hole 24 of the same shape provided in a portion covered by the U-shaped metal fitting 13 on the side surface of the mounting metal fitting 12. The slanted tip of the lock knob 17 is also attached to the mounting bracket 12.
It protrudes inside the mounting bracket 12 from the escape hole 25 on the side surface while being pushed by the leaf spring 22. As a result, by applying force to the head of the lock knob protruding from the U-shaped fitting 13, the protrusion 18
The tip rotates around the fulcrum. Further, a recess 10 is formed above the guide groove 11 provided on the side surface of the electronic device 9 at a position where the lock knob 17 is engaged.

With this structure, the mounting bracket 12 is fixed to the bottom of a car's dash board or the like through the mounting hole 15 on the top surface, and the opposing guide pieces 16 are engaged with the guide groove 11 of the electronic device. When the electronic device 9 is slid, the lock knob 17 fits into the recess 10 and the electronic device 9 is fixed to the mounting bracket 12. In addition, when removing the lock knob 17, by pressing the head of the lock knob 17, the tip rotates about the protrusion 18 as a fulcrum, and can be easily removed from the recess 10. Therefore, the troublesomeness of the conventional screw fastening method is eliminated, and the one-touch method can be used, so that the operability of attaching and detaching can be improved.

In addition, there is a screw hole 2 near the head of the lock knob 17.
1 is provided, and a hole 14 is provided at a position matching the screw hole 21 near the open end of the U-shaped metal fitting 13. As a result, if the lock knob 17 is tightened with the set screw 26 while the electronic device 9 and the lock knob 17 are fitted together, the electronic device 9 can be prevented from being stolen. You can also take advantage of your strengths. Also,
By providing the recess 10 on the side of the electronic device 9 at the same position in the front-back direction on the opposite side and below the guide groove, it is possible to fix the electronic device upside down, and the installation of the mounting bracket 12 is easy. Depending on the location, even if the need arises, it can be easily accommodated. Furthermore, when assembling the mounting bracket 12, the circular protrusion 20 of the lock knob 17 and the locking hole 23 of the leaf spring are engaged, and the protrusion 18 is inserted into the gap of the U-shaped bracket 13 from the open end. Fulcrum hole 2
4, it becomes assembled and can be assembled very easily.

As described above, the in-vehicle electronic device mounting device of the present invention forms a certain gap by providing a part of the outer surface of the mounting bracket so as to cover the U-shaped bracket.
It has a structure in which a lock knob with a protrusion that serves as a fulcrum is incorporated together with a leaf spring, and the tip of the lock knob, which is biased by the leaf spring, fits into a recess provided on the side of the electronic device. It has excellent practical features, such as being able to easily attach and detach devices to and from the mounting bracket with a single touch, and at the same time easily respond to requests for reverse insertion of electronic devices.
