Description

Technical Field

[0001] This utility model relates to the field of vehicle sensor technology, and in particular to a vehicle sensor for an automatic phase-crossing system. Background Technology

[0002] Automatic phase-crossing systems are used in Harmony electric locomotives, Fuxing bullet trains, Malaysian EMUs, Mumbai electric locomotives in India, and Lao 160 km / h centralized power EMUs. With the development of railways and the continuous increase in speed, the automatic phase-crossing system has caused serious damage. 304 stainless steel is used as the outer shell. However, the 304 stainless steel shell shields the signal too severely, affecting signal reception.

[0003] To address this issue, we propose an improved vehicle sensor for an automatic phase-crossing system to resolve the problem of excessive signal shielding affecting signal reception. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vehicle sensor for an automatic phase-crossing system.

[0005] An automatic phase-crossing system vehicle sensor includes a lower housing, a cable, an upper housing, an iron core, a protective sleeve, a protective sleeve bracket, an elbow, ferrite, a vehicle sensor coil, and a sealing epoxy resin. The iron core and ferrite are disposed inside the lower housing. The upper housing is fixedly connected to the lower housing, iron core and ferrite by screws. The upper housing is provided with a through hole. One end of the elbow is fixedly connected to the through hole, and the other end of the elbow is fixedly connected to the protective sleeve. The protective sleeve is installed on the upper end face of the upper housing through the protective tube bracket. The cable is disposed inside the protective sleeve and passes through the elbow and the through hole to connect to the vehicle sensor coil wound on the iron core and ferrite.

[0006] Furthermore, the lower housing is cylindrical and made of stainless steel.

[0007] Furthermore, the sealing epoxy resin is filled into the lower housing to further fix the iron core, ferrite and vehicle sensor coil.

[0008] Compared with the prior art, the present invention has the following beneficial effects: This invention has a simple structure and is easy to use. It uses iron core and ferrite as the magnetic materials for the receiving coil, which solves the problem of large changes in the amplitude of the received pulse caused by the large range of vehicle speed changes, which makes the main control system unstable. The received signal is stable and there are no missing codes, making it suitable for widespread application. Attached Figure Description

[0011] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 As shown, an automatic phase-crossing system vehicle sensor includes a lower housing 1, a cable 2, an upper housing 3, an iron core 5, a protective sleeve 6, a protective sleeve bracket 7, an elbow 8, a ferrite 9, a vehicle sensor coil 10, and a sealing epoxy resin adhesive 11. The iron core 5 and ferrite 9 are housed in the lower housing 1. The upper housing 3 is fixedly connected to the lower housing 1, iron core 5 and ferrite 9 by screws. The upper housing 3 is provided with a through hole 4. One end of the elbow 8 is fixedly connected to the through hole 4, and the other end of the elbow 8 is fixedly connected to the protective sleeve 6. The protective sleeve 6 is installed on the upper end surface of the upper housing 3 through the protective tube bracket 7. The cable 2 is housed in the protective sleeve 6 and passes through the elbow 8 and the through hole 4 to connect to the vehicle sensor coil 10 wound on the iron core 5 and ferrite 9. The use of iron core 5 and ferrite 9 as the magnetic conductive materials of the receiving coil solves the problem of large changes in the amplitude of the received pulse caused by the large range of vehicle speed changes, which makes the main control system unstable.

[0013] The lower housing 1 is cylindrical and made of 304 stainless steel, which improves the corrosion resistance of the vehicle sensor.

[0014] Among them, the sealing epoxy resin 11 is filled into the lower housing 1 to further fix the iron core 5, ferrite 9 and vehicle sensor coil 10, while improving the sealing performance of the vehicle sensor.

[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
