In order to make the fixing base 200 more firmly connected to the half-axle sleeve 100, in an embodiment of the present invention, the half-axle sleeve 100 is further provided with a limiting groove 100 a. Specifically, the limiting groove 100a is a material shortage formed on the outer peripheral surface of the half-shaft sleeve 100, the limiting groove 100a is annularly arranged on the outer peripheral surface of the half-shaft sleeve 100, the annular center coincides with the axis of the half-shaft sleeve 100, and the positioning convex rib 110 is partially accommodated in the limiting groove 100a, that is, the positioning convex rib 110 extends outwards from the bottom wall of the limiting groove 100a, and the positioning convex rib 110 can protrude out of the opening end of the limiting groove 100a, or can be completely accommodated in the limiting groove 100 a. The width of the limiting groove 100a should be slightly smaller than the thickness of the fixing base 200, that is, the limiting groove 100a and the fixing base 200 are in interference fit. After the fixing base 200 is clamped to the positioning ribs 110 through the positioning clamping grooves 200a, the two opposite side surfaces of the fixing base 200 abut against the groove side walls of the limiting grooves 100a, so that the fixing base 200 is fixed more firmly.

Referring again to fig. 2 and 3, in order to facilitate the assembly and disassembly of the sensor 300, in an embodiment of the present invention, the sensor fixing structure 10 further includes a mounting member 400. Specifically, the mounting member 400 is formed by a sheet metal material through a bending process, the mounting member 400 includes a first section, a second section and a third section which are connected, the first section and the third section extend linearly, two ends of the second section are connected to the first section and the third section respectively, the second section extends in a circular arc shape, the outline of the second section is adapted to the outline of the sensor 300, and the first section and the third section are detachably connected to the fixing base 200. In an embodiment of the present application, the fixing base 200 is provided with a connecting hole 200b, the connecting hole 200b is a threaded hole or a pin hole, the first section and the third section are provided with a mounting hole 400a, the mounting hole 400a can be a through hole or a threaded hole, and when the connecting hole 200b is a threaded hole, the connecting member 500 is correspondingly provided as a screw; when the connecting hole 200b is a pin hole, the connecting rod is correspondingly provided as a pin. The sensor 300 is placed on the surface of the fixing base 200, the second section is attached to the surface of the sensor 300, the connecting member 500 is inserted into the mounting hole 400a and the connecting hole 200b, and the sensor 300 is pressed on the surface of the fixing base 200. The installation and fixation of the sensor 300 in the present application is simple and the sensor 300 can be more firmly fixed to the half-shaft bushing 100. In an embodiment of the present application, two sides of the mounting member 400 are provided with fastening holes, and the surface of the fixing base 200 facing the mounting member 400 is convexly provided with a locking protrusion, which is locked in the fastening holes. The sensor 300 can be pressed on the surface of the fixing base 200.

It can be understood that, in the present application, the mounting member 400 is made of a sheet metal material, and when the mounting member 400 presses the sensor 300 on the surface of the fixing base 200, in order to avoid the sensor 300 from rigidly abutting against the mounting member 400 and the fixing base 200, the sensor 300 is crushed. In an embodiment of the present invention, the sensor fixing structure 10 further includes a protective sleeve 600, and specifically, the protective sleeve 600 is made of an elastic material, such as: silicone or rubber. The protective sleeve 600 is disposed in a cylindrical shape and sleeved on the outer side surface of the sensor 300, and when the mounting member 400 presses the sensor 300 on the fixing base 200, the protective sleeve 600 elastically abuts against the mounting member 400 and the fixing base 200. Thus, the sensor 300 can be prevented from being crushed by the elastic buffer action of the protective sleeve 600. And because protective sheath 600 that elastic material made has great coefficient of friction, consequently installed part 400 and fixing base 200 butt behind protective sheath 600, protective sheath 600 elasticity butt in sensor 300's surface, form great frictional force between the two to make sensor 300 be difficult to loosen from protective sheath 600 and take off, make sensor 300's installation more firm.

Referring to fig. 3 again, in an embodiment of the invention, a plurality of abutting rib positions 610 are formed on the outer side surface of the protective sheath 600 in a protruding manner. Specifically, the protruding lateral surface of locating protective sheath 600 of this butt muscle position 610 to the axis direction along protective sheath 600 extends the setting, and butt muscle position 610 is connected in protective sheath 600 including the first section and the second section that are connected, and the rectangle setting is personally submitted in the first section, and the second section is triangle-shaped setting, and butt muscle position 610 sets up along the radial even interval of protective sheath 600. After the sensor 300 is pressed to the fixing base 200 by the mounting member 400, the second section of the abutting rib 610 abuts against the mounting member 400. After the force analysis, it can be known that, after the plurality of abutting rib positions 610 abut against the mounting member 400, because the contact area between the abutting rib positions 610 and the mounting member 400 is small, the positions of the abutting rib positions 610 can generate large compressive stress, and the compressive stress acts on the surface of the sensor 300, so that the connection between the sensor 300 and the protective sleeve 600 is tighter.
