Description

Technical Field

[0001] The utility model relates to the technical field of automobile sensors, in particular to a mounting structure of a seat position sensor. Background Art

[0002] The main purpose of the car seat position sensor is to detect the seat position and feed the seat position back to the car's ECU (electronic control unit). When the car collides, the airbag will pop out. Since the seat is close to the steering wheel, the airbag may pop out with too much force, causing secondary injuries to the owner. The seat position sensor detects the magnetic field change of the magnet through the Hall chip and outputs I off value (cut-off current) and I on Value (conduction current). In the current seat position sensor, the Hall chip is mounted on the seat rail, and the magnet is mounted on the rail, so there is an error in the detected magnetic field change. Therefore, considering changing the structure of the seat position sensor, installing the magnet and the Hall chip into the seat position sensor at the same time, but this requires improving the installation structure of the existing seat position sensor.

One side of the guide rail 1 has a guide rail opening, and two edges of the guide rail opening are folded inward to form an inwardly buckled flange 11. One side of the slide rail 2 has a slide rail opening arranged opposite to the guide rail opening, and two edges of the slide rail opening are folded outward to form an outer flange 21 overlapping the flange 11. One end of the slide rail 2 is connected to a fixing clip 4, and the fixing clip 4 is connected to the seat position sensor 3.

[0024] Among them, a plurality of clamping holes 12 are provided on the side wall of the guide rail 1, and a transverse Z-shaped metal sheet 5 is provided near one end of the side wall of the guide rail 1. A transverse section of the transverse Z-shaped metal sheet 5 passes through the side wall of the guide rail 1, and a longitudinal section of the transverse Z-shaped metal sheet 5 fits the side wall of the guide rail 1. A through hole 51 is provided on the transverse section of the transverse Z-shaped metal sheet 5 passing through the side wall of the guide rail 1. A longitudinal Z-shaped connecting sheet 6 is fixed near one end of the top surface of the slide rail 2, and a connecting hole 61 is provided in the upper transverse section of the longitudinal Z-shaped connecting sheet 6.

[0025] like Figure 3As shown, the fixing clamp 4 includes a support plate 41, a first connection portion 42 is provided on the upper surface of the support plate 41, and the first connection portion 42 has three first arc-shaped protrusions 421 with a common center axis, and a second connection portion 43 is provided on the lower surface of the support plate 41 at a position corresponding to the first connection portion 42, and the second connection portion 43 has three second arc-shaped protrusions 431 with a common center axis, and a hook portion 4311 is formed at the lower portion of the second arc-shaped protrusion 431. One end of the support plate 41 has a hollow cylinder 44 extending downward, and the bottom edge of the hollow cylinder 44 is provided with a convex edge 441. The surface of the support plate 41 near the hollow cylinder 44 protrudes upward to form a barb 45. Combined with Figure 2 As shown, the surface of the slide rail 2 is provided with a first mounting hole 22 for the second connecting portion 43 to pass through and a second mounting hole 23 for the hollow column 44 to pass through.

[0026] like Figure 4 and Figure 5 As shown, the seat position sensor 3 has a housing 31, the housing 31 has a mounting groove 311, a support frame 32 is arranged in the mounting groove 311, a magnet 33 and a Hall chip 34 are arranged on the support frame 32, the Hall chip 34 has two pins 341, the pins 341 bypass the top of the support frame 32 and contact the conductive sheet 35 fixedly arranged at the front of the support frame 32, the conductive sheet 35 is connected to the wire harness 36, a plurality of buckles 312 for arranging the wire harness are arranged on the housing 31 below the mounting groove 311, one end of the housing 31 has a connecting portion 37 of a cylindrical structure, a plurality of latch teeth 371 are protruding on the inner wall of the connecting portion 37, and a latch groove 372 matching with the first arc-shaped protrusion 431 is formed between adjacent latch teeth 371. A latch hook 38 connected with the barb 45 is arranged obliquely downward below the connecting portion 37.

[0027] The seat position sensor 3 is installed with the magnet 33 and the conductive sheet 35 by insert injection molding, eliminating the PCB board, optimizing the structure and reducing the assembly cost. In this way, the installation structure of this embodiment installs the seat position sensor 3 on one end of the slide rail 2 through the fixing clip 4, and moves with the slide rail 2.
