Abstract

Disclosed is a device for attaching a sensor for a TPMS. The device for attaching a sensor for a TPMS includes: a module housing including a sensor module for a TPMS; a binding unit including a wire that is long enough to be wrapped on a wheel circumference portion of a vehicle and a rotation shaft installed in the module housing to wind or unwind the wire by a normal/reverse rotation; an engaging and fixing unit including an engaged groove and an engaged protrusion formed to generate an engaging and contacting force while being able to control an unwinding rotation corresponding to the rotation shaft of the binding unit; and a rotation unit disposed to rotate the rotation shaft of the binding unit and formed to release an engaging and contacting state of the engaging and fixing unit in connection with the rotating.

Claims

1. A device for attaching a sensor for a tire pressure monitoring system (TPMS), comprising:

a module housing including a sensor module for a TPMS;

a binding unit including a wire that is long enough to be wrapped on a wheel circumference portion of a vehicle, and a rotation shaft installed in the module housing to wind or unwind the wire by a normal/reverse rotation;

an engaging and fixing unit including an engaged groove and an engaged protrusion formed to generate an engaging and contacting force while being able to control an unwinding rotation corresponding to the rotation shaft of the binding unit; and

a rotation unit disposed to rotate the rotation shaft of the binding unit and formed to release an engaging and contacting state of the engaging and fixing unit in connection with the rotating,

wherein the rotation shaft of the binding unit includes a bobbin installed in the module housing, the bobbin configured to rotate while the wire is wound on or unwound from the bobbin by the normal/reverse rotation.

2. The device of claim 1, wherein

the module housing includes a drawing out unit for allowing the wire of the binding unit to draw to an outside, and a support unit for engaging the drawn wire to enable a binding operation while the drawn wire wraps a wheel circumference portion of the vehicle.

3. The device of claim 1, wherein

at least one strand of the wire of the binding unit is connected and formed so as to be wound on or unwound from the rotation shaft.

4. The device of claim 3, wherein

the wire is connected and fixed to the rotation shaft by a pressing and contacting force of a fastener, and

the fastener uses a set screw.

5. The device of claim 1, wherein,

regarding the engaging and fixing unit,

the engaged groove is formed on the module housing while forming a groove unit in a ring type and inscribed gear type forming a same shaft as the rotation shaft of the binding unit, and

the engaged protrusion is formed while configuring a protrusion unit flexibly engaged to the engaged groove and generating a one-directional engaging and contacting force by a rotation operation while combined to a rotation shaft of the binding unit.

6. The device of claim 5, wherein,

regarding the engaged groove and the engaged protrusion,

when the rotation shaft is rotated to be wound, the protrusion unit is set to climb over the groove unit and generate a one-directional engaging and contacting force for being rotatable in winding the rotation shaft and being limited in the unwinding.

7. The device of claim 1, wherein

the rotation unit includes:

a release unit for releasing an engaging and contacting state of an engaged groove and an engaged protrusion of the engaging and fixing unit in connection with a rotating operation; and

a guide unit for guiding an operation of the release unit, and

the rotation unit is installed in the module housing to allow normal/reverse rotations with respect to an axis line of a rotation shaft of the binding unit.

8. The device of claim 7, wherein

the release unit is formed to generate a contacting force while an engaged protrusion moves so as to release the engagement on the engaged groove when the rotation unit is unwound with respect to an axis line of the rotation shaft.

9. The device of claim 7, wherein

the guide unit includes a guide protrusion and a guide groove that are inserted into each other and are combined so as to generate a connection state for rotating the engaged protrusion while the release unit is available for an operation when the rotation unit is operated.

10. The device of claim 9, wherein

the guide groove is formed to be extended in a long groove form so that the release unit may perform a release operation without interference with the guide protrusion within a predetermined rotation angle when the rotation unit is unwound.

11. The device of claim 1, wherein

the sensor attaching device for a TPMS further includes

an operation lever corresponding to the rotation unit, and

the operation lever is formed to be attachable/detachable to/from the rotation unit according to insertion and combination and is formed to rotate the rotation unit in a normal/reverse rotation direction.

12. A device for attaching a sensor for a tire pressure monitoring system (TPMS), comprising:

a module housing including a sensor module for a TPMS;

a binding unit including a wire that is long enough to be wrapped on a wheel circumference portion of a vehicle, and a rotation shaft installed in the module housing to wind or unwind the wire by a normal/reverse rotation;

an engaging and fixing unit including an engaged groove and an engaged protrusion formed to generate an engaging and contacting force while being able to control an unwinding rotation corresponding to the rotation shaft of the binding unit; and

a rotation unit disposed to rotate the rotation shaft of the binding unit and formed to release an engaging and contacting state of the engaging and fixing unit in connection with the rotating,

wherein the module housing includes a drawing out unit for allowing the wire of the binding unit to draw to an outside, and a support unit for engaging the drawn wire to enable a binding operation while the drawn wire wraps a wheel circumference portion of the vehicle.

13. The device of claim 12, wherein

at least one strand of the wire of the binding unit is connected and formed so as to be wound on or unwound from the rotation shaft.

14. The device of claim 13, wherein

the wire is connected and fixed to the rotation shaft by a pressing and contacting force of a fastener, and

the fastener uses a set screw.

15. The device of claim 12, wherein

the sensor attaching device for a TPMS further includes

an operation lever corresponding to the rotation unit, and

the operation lever is formed to be attachable/detachable to/from the rotation unit according to insertion and combination and is formed to rotate the rotation unit in a normal/reverse rotation direction.

16. A device for attaching a sensor for a tire pressure monitoring system (TPMS), comprising:

a module housing including a sensor module for a TPMS;

a binding unit including a wire that is long enough to be wrapped on a wheel circumference portion of a vehicle, and a rotation shaft installed in the module housing to wind or unwind the wire by a normal/reverse rotation;

an engaging and fixing unit including an engaged groove and an engaged protrusion formed to generate an engaging and contacting force while being able to control an unwinding rotation corresponding to the rotation shaft of the binding unit; and

a rotation unit disposed to rotate the rotation shaft of the binding unit and formed to release an engaging and contacting state of the engaging and fixing unit in connection with the rotating,

wherein, regarding the engaging and fixing unit,

the engaged groove is formed on the module housing while forming a groove unit in a ring type and inscribed gear type forming a same shaft as the rotation shaft of the binding unit, and
