## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to the technical field of tire pressure monitoring devices and more particularly to a fixing element adapted for a tire pressure monitoring device.
2. Description of Related Art
Nowadays, a car can be mounted with an additional tire pressure monitoring system (TPMS) to enhance the driver's and passengers' safety. Be it of the pointer type or equipped with an electronic display, each tire pressure monitoring device of the system can measure the real-time pressure, temperature, or like data of a car tire before the car is started or while the car is running, in order to ensure the driver's and passengers' safety on the road.
To mount a tire pressure monitoring device to a car tire, it is typically required to tie or fix the base of the device to a wheel's rim or in the tire. However, a tire pressure monitoring device thus mounted may become loose or even shifted in place when the car is running. Should this happen to any tire pressure monitoring device of a car, a significant error may occur in the real-time measurements of tire pressure, tire temperature, or like data while the car is running and have an indirect impact on the driver's and passengers' safety on the road.
In light of the above, the present invention aims to overcome the aforesaid drawbacks of the prior art by finding a way to effectively secure a tire pressure monitoring device at its initial position.
BRIEF SUMMARY OF THE INVENTION
In view of the aforesaid drawbacks of the prior art, it is an objective of the present invention to provide a fixing element adapted for a tire pressure monitoring device. It is highly desirable that the fixing element provides significant improvement not only on the fixed state of the tire pressure monitoring device with respect to the fixing element, but also on the secureness of the tire pressure monitoring device at its initial position, so as to achieve the intended effect and objective of the invention.
To achieve the foregoing objective, the present invention provides a fixing element which is adapted for a tire pressure monitoring device and which includes a base, a locking portion, and at least two stop blocks.
The base is composed of a first plate and two second plates. The two second plates are connected to two corresponding lateral sides of the first plate respectively such that the base has an elongated shape. The base has a top side and a bottom side corresponding to the top side. The bottom side of the base can be tightly attached to the rim of a wheel by bending each of the two second plates of the base by a predetermined angle. Each of the two second plates of the base has a body portion penetrated by an aperture through which an annular member can pass.
The locking portion has one end connected to a long side of the base and the opposite end extending upward from the top side of the base. The locking portion has a through hole, and a fixing member can pass through the through hole in order to be fixed to the tire pressure monitoring device.
The two stop blocks are provided on the two second plates of the base respectively and are raised upward from a reference plane defined by the top side of the base.

DETAILED DESCRIPTION OF THE INVENTION
The structural features of the present invention and their intended effects are described in more detail below with reference to some illustrative embodiments in conjunction with the accompanying drawings. Please note that the same reference numerals used in the embodiments and the drawings refer to identical or similar elements, components, articles, structures, systems, architectures, devices, process flows, methods, or steps.
Referring to FIG. 1 to FIG. 4, the present invention provides a fixing element 10 adapted for a tire pressure monitoring device 200, wherein the fixing element 10 includes a base 20, a locking portion 30, and at least two stop blocks 40.
The base 20 is composed of a first plate 21 and two second plates 23. The two second plates 23 are connected to two corresponding lateral sides of the first plate 21 respectively such that the base 20 has an elongated shape. The base 20 has a top side 202 and a bottom side 204 corresponding to the top side 202. The bottom side 204 of the base 20 can be tightly attached to the rim 101 of a wheel by bending each of the two second plates 23 of the base 20 by a predetermined angle. Each of the two second plates 23 of the base 20 has a body portion penetrated by an aperture 231. An annular member 103 can be passed sequentially through the apertures 231 and then fixed to the rim 101. In addition, each of the two second plates 23 has an extended section 232, and the two second plates 23 are connected to the first plate 21 through their respective extended sections 232.
In this embodiment, the first plate 21 and the two second plates 23 of the base 20 and the extended sections 232 of the two second plates 23 are all flexible, or bendable. The base 20 further has two protective members 25 provided on the top side 202 of the base 20. Each of the two protective members 25 is raised from the periphery of the aperture 231 of one of the two second plates 23 of the base 20 and forms a pull-ring structure. The annular member 103 is confined within the pull-ring structures of the protective members 25 after being passed sequentially through the apertures 231 of the two second plates 23.
The locking portion 30 has one end connected to a long side of the base 20. The opposite end of the locking portion 30 extends upward from the top side 202 of the base 20. The locking portion 30 has a through hole 31. A fixing member 201 can be passed through the through hole 31 and then fixed to the tire pressure monitoring device 200. In this embodiment, the fixing member 201 includes but is not limited to a tenon, a rivet, or a screw.
The at least two stop blocks 40 are provided on the two second plates 23 of the base 20 respectively and are raised in a direction away from the top side 202 of the base 20. In this embodiment, four stop blocks 40 are provided in pairs, and each pair of stop blocks 40 are adjacent to one of the two apertures 231 of the base 20. Each of the two protective members 25 is adjacent to one of the two pairs of stop blocks 40.
This embodiment is notably distinguished from the prior art by the following effects and technical features. First of all, the fixing element 10 is attached to the rim 101. Then, one open end of the annular member 103 is passed through the two apertures 231 of the base 20 of the fixing element 10 successively. After that, the bottom side 204 of the base 20 is tightly attached to the rim 101 thanks to the bendability of the first plate 21 and the two second plates 23 of the base 20 and of the extended sections 232 of the two second plates 23. Next, the two open ends of the annular member 103 are connected and are fastened with a fastener 105 such that both the fixing element 10 and the annular member 103 are radially tightly fixed to the rim 101 while the annular member 103 encircles the rim 101. Following that, the tire pressure monitoring device 200 is mounted on the fixing element 10, with the bottom portion of the tire pressure monitoring device 200 pressed against the two pairs of stop blocks 40, and the fixing member 201 is passed through the through hole 31 of the locking portion 30 of the fixing element 10 and then fixed to the tire pressure monitoring device 200 to conclude the mounting process of the fixing element 10 of the present invention and the tire pressure monitoring device 200.
According to the above, the technical features of the components of the fixing element 10 adapted for the tire pressure monitoring device 200 prevent contact between the bottom portion of the tire pressure monitoring device 200 and the annular member 103, thereby avoiding any indirect impact such contact may have on the fixed state of the tire pressure monitoring device 200 with respect to the locking portion 30 of the fixing element 10. This allows the tire pressure monitoring device 200 to stay securely at its initial mounting position to achieve the intended effect and objective of the present invention.
