Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air pressure sensor mounting structure for measuring the internal pressure of a pneumatic tire, and more particularly to an air pressure sensor mounting structure mounted on a part of a rim of a tire wheel.
[0002]
[Prior art]
2. Description of the Related Art In recent years, in consideration of safe driving and riding comfort of a vehicle, a tire provided with a pressure sensor for measuring tire internal pressure has been proposed. As for the tire internal pressure, a temporary reference internal pressure is defined according to the weight of the vehicle body, the running speed, etc. corresponding to the tire diameter, but it is difficult to always grasp the tire internal pressure.
[0003]
In recent years, run-flat tires that can be used even if the tires are punctured are used, but it is extremely dangerous when traveling at high speed in a punctured state, and it is determined whether the tires are punctured. Since there is a problem that it is difficult to check at the time of traveling, a tire provided with a pressure sensor for measuring the tire internal pressure is commercially available.
[0004]
This pressure sensor constantly measures the pressure in the tire, and for example, a measured signal is output so that the tire internal pressure can be confirmed from the driver's seat or the like.
[0005]
[Problems to be solved by the invention]
By the way, the conventional air pressure sensor has been mainly attached to an air injection valve mounted on a tire rim via a nut or the like.
[0006]
However, the air pressure sensor mounted integrally with the air injection valve is easy to loosen the mounting part of the air pressure sensor and may come off from the air injection valve and move inside the tire together with the tire during travel. There was a problem.
[0007]
Furthermore, since the air pressure sensor is mounted integrally with the air injection valve, there is a problem that it takes a lot of labor and time to change the mounting position of the air pressure sensor, and to mount and remove it.
[0008]
An object of the present invention is to provide a pneumatic sensor mounting structure that can easily mount and remove the air pressure sensor and can easily change the mounting position of the air pressure sensor.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a sensor holder, which is formed by punching a material that can be elastically held and bending it so that the upper part is open. Is detachably clamped by the sensor holder .
[0011]
As described above, when attaching the air pressure sensor to a part of the rim of the tire wheel, the air pressure sensor can be easily attached and detached through the sensor holder attached to the part of the rim. In addition, the mounting position of the air pressure sensor can be easily changed.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0013]
FIG. 1 is a perspective view of a tire in which a pneumatic sensor according to the present invention is attached to a part of a tire wheel through a sensor holder. FIG. 1 shows a tire, 2 is a tire wheel, 3 is a rim, rim flange, 5 indicates a pressure sensor, the pressure sensor 5, to the rim 3 via the vertical sensor holder 7 as shown in horizontal sensor holder 6 or FIG. 4, as shown in FIG. 3 Removably attached.
[0014]
As shown in FIG. 2, the air pressure sensor 5 includes a detector (not shown) in a synthetic resin container 8, for example, and a part of the container 8 is small enough to detect the pressure in the tire 1. A hole 9 is provided.
[0015]
Further, the horizontal sensor holder 6 in the first embodiment of the present invention shown in FIG. 3 is configured to hold the air pressure sensor 5 in the horizontal direction, and the structure thereof is, for example, a pneumatic pressure by punching and bending a stainless spring plate material. The outer shell of the sensor 5 is configured to be elastically held.
[0016]
That is, the sensor holder 6 is opposed to the base portion 6a that is fixed laterally to the rim 3 by an adhesive made of a thermoplastic resin material, welding, or the like. Both sides 6b, 6b are bent at a right angle and raised, and upper ends 6c, 6c are bent inward, and opposite longitudinal sides 6d, 6d are folded downward to bend end portions 6e, 6e upward. Formed.
[0017]
The base portion 6a is preferably formed with a curvature corresponding to the diameter of the rim 3 so that the base portion 6a can be fixed to the curvature of the rim 3 without causing play.
[0018]
Therefore, the substantially rectangular air pressure sensor 5 is held so as to be sandwiched from the left and right sides in the longitudinal direction with both side edges 6b and 6b being expanded in the direction of the arrow, and the end surfaces in the longitudinal direction are held by the terminal portions 6d and 6d. Therefore, the sensor holder 6 is detachably held.
[0019]
FIG. 4 is a perspective view showing a second embodiment of the sensor holder. The vertical sensor holder 7 is configured to hold the air pressure sensor 5 in a vertical orientation, and the configuration thereof is the horizontal type described above. Similar to the sensor holder 6, the stainless steel spring plate is punched and bent so that the outline of the air pressure sensor 5 can be elastically held.
[0020]
That is, the sensor holder 7 is provided with a plurality of holes 11 in the longitudinal direction and is opposed to the base portion 7a that is laterally fixed to the rim 3 by an adhesive or welding made of a thermoplastic resin material. Both sides 7b, 7b are bent at right angles, and upper end portions 7c, 7c are formed to be bent inward so that the outer shell of the air pressure sensor 5 can be held and fixed.
[0021]
Further, side sides 7d and 7d opposite to each other in the width direction with respect to the base portion 7a are formed in an overhang portion corresponding to the width of the air pressure sensor 5, and the terminal portions 7e and 7e are bent upward at a right angle. It is formed so as to hold the side surface of the air pressure sensor 5.
[0022]
The base portion 7a is preferably formed with a curvature corresponding to the diameter of the rim 3 so that the base portion 7a can be fixed to the curvature of the rim 3 without causing play.
[0023]
Therefore, the substantially rectangular air pressure sensor 5 is held so as to be sandwiched from the side surface in the longitudinal direction of the air pressure sensor 5 in a state where both opposite sides 7b and 7b in the longitudinal direction are expanded in the direction of the arrow. The side surface is detachably held by the opposite side sides 7d and 7d and the terminal portions 7e and 7e.
[0024]
The horizontal sensor holder 6 or the vertical sensor holder 7 of each embodiment is formed of a stainless spring plate material, but is not limited to this material, and may be formed of a resin material. In this case, the sensor holders 6 and 7 are fixed by an adhesive made of a thermoplastic resin material.
[0025]
As described above, according to the present invention, when the air pressure sensor 5 is attached to a part of the rim 3 of the tire wheel 2, it is attached detachably via the sensor holder 6 or 7 attached to a part of the rim 3. The air pressure sensor 5 can be easily attached and detached, and the air sensor 5 can be easily attached at a different position.
[0026]
【The invention's effect】
Since the pneumatic sensor is detachably attached to the sensor holder attached to a part of the rim as described above, the present invention has the following excellent effects.
(a) Air pressure sensor can be easily attached and removed, so even when the tire mounting position is changed, it is a cassette system, so it can be flexibly adapted to position exchange, and the air sensor battery can be replaced. Can also be done easily.
(b) By holding the sensor holder in accordance with the curvature of the rim, only one type of air pressure sensor case can be used, and costs can be reduced.
(c) By using an adhesive made of thermoplastic resin to fix the sensor holder and rim, the sensor holder can be easily removed by simply applying heat when replacing or disposing of the vehicle. Convenient for waste disposal.
