[0021] See also Figure 1-6 The utility model provides an automobile wheel hub bearing with a sensor seat, comprising a bearing body 1, a mounting seat 2 is fixed to the surface of the bottom of the bearing body 1, a heat-conducting ring 3 is fixed to the inner circumference of the mounting seat 2, the top of the heat-conducting ring 3 extends to the inner cavity position of the bearing body 1 and fits with the inner circumference of the bearing body 1, a first inner groove 4 is provided on the outer circumference of the mounting seat 2, a plurality of temperature sensor bodies 5 are arranged inside the first inner groove 4, a heat-conducting block 6 is fixed to the side of the temperature sensor body 5 close to the heat-conducting ring 3, the surface of the heat-conducting block 6 close to the side of the heat-conducting ring 3 fits with the inner circumference of the mounting seat 2, and two heat-conducting rings 3 are arranged on the outer circumference of the mounting seat 2. The casing 12 has a second inner groove 16 formed on its inner circumference, and a plurality of threaded rods 13 are threadedly connected at the middle position of the casing 12, one side of the threaded rod 13 extends to the inner cavity position of the second inner groove 16, and a rubber pad 14 is fixed to the threaded rod 13 at the inner cavity position of the second inner groove 16, and one side of the rubber pad 14 fits with the surface of the temperature sensor body 5 at the adjacent position, so that the temperature sensor body 5 can be placed in the cavity formed by the mounting seat 2 and the first inner groove 4 and the second inner groove 16 inside the casing 12 to wrap the temperature sensor body 5, thereby preventing the temperature sensor body 5 from being damaged by the infiltration of moisture.

[0022] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that a positioning groove 7 is provided on the surface of the bottom of the first inner groove 4, and a positioning block 8 is slidably inserted inside the positioning groove 7. The top of the positioning block 8 passes through the adjacent positioning groove 7 and is fixed to the surface of the bottom of the adjacent temperature sensor body 5. The position of the positioning block 8 can be limited by the positioning groove 7, so that the positions of the temperature sensor body 5 and the heat conductive block 6 can be limited under the connection relationship of the positioning groove 7.

[0023] Further as Figure 3 As shown, it is worth specifically explaining that the surfaces of the mounting seat 2 located at the upper and lower ends of the first inner groove 4 are provided with symmetrically distributed sealing grooves 9, and sealing rings 10 are inserted inside the sealing grooves 9. The outer peripheral surface of the sealing ring 10 passes through the sealing grooves 9 and is fixed to the surface of the casing 12. A plurality of threaded holes 15 are penetrated through the surface of one of the sealing rings 10, and a bolt 11 is threadedly connected through the middle position of the threaded hole 15. The bottom of the bolt 11 passes through the mounting seat 2 and extends to the bottom position of the mounting seat 2. When the two casings 12 are fitted and connected to the mounting seat 2, the sealing ring 10 can extend to the inside of the sealing groove 9 at the adjacent position, thereby improving the sealing performance when the casing 12 is connected to the mounting seat 2, and one of the sealing rings 10 can be fixed by the cooperation of the threaded connection between the bolt 11 and the threaded hole 15.

[0024] Further as Figure 3 As shown, it is worth explaining in detail that one end of the second inner groove 16 is connected to a plurality of exhaust holes 17 which are equidistantly distributed around the inner surface of the exhaust hole 17, and a filter screen 18 is fixed to the inner surface of the exhaust hole 17. One side of the inner cavity of the exhaust hole 17 is inclined. The exhaust holes 17 are arranged to facilitate heat dissipation of the inner cavities of the first inner groove 4 and the second inner groove 16. At the same time, the second inner groove 16 is arranged to prevent external dust from entering the first inner groove 4 and the second inner groove 16, and the shape of the exhaust holes 17 is arranged to prevent external moisture from penetrating.

[0025] This solution has the following working process: in actual use, when the user needs to install the temperature sensor body 5 inside the mounting seat 2 to monitor the temperature of the bearing body 1, the positioning block 8 is inserted into the positioning groove 7 at the adjacent position and the positioning block 8 is pushed so that the temperature sensor body 5 and the heat-conducting block 6 can move in the direction close to the bearing body 1 until the surface of the heat-conducting block 6 can fit with the inner circumferential surface of the first inner groove 4. Since the heat-conducting ring 3 can transfer the heat from the inner circumferential surface of the bearing body 1 to the surface of the mounting seat 2 during monitoring, and then the heat can be transferred to the position of the temperature sensor body 5 through the heat-conducting block 6, the temperature sensor body 5 can monitor the transferred temperature. Subsequently, the two sleeves 12 are wrapped around the outside of the mounting seat 2 so that the sealing ring 10 can extend to the inside of the sealing groove 9 at the adjacent position, and then the bolt 11 is rotated to extend to the second inner groove 16 at the adjacent position. Inside, one of the sealing rings 10 can be limited, so that the two shells 12 can be connected to the mounting seat 2, so that the shell 12 can wrap the inner cavity of the first inner groove 4 inside so that the temperature sensor body 5 can be isolated from the external environment, and then the threaded rod 13 is rotated so that the threaded rod 13 extends in the horizontal direction through the cooperation with the threaded structure between the shells 12 at the adjacent position, until the surface of the rubber pad 14 can conflict with the surface of the temperature sensor body 5, so that the heat-conducting block 6 can fully fit with the inner circumference of the first inner groove 4 to ensure the stability of monitoring, and the exhaust hole 17 is arranged to facilitate the heat dissipation of the inner cavity of the first inner groove 4 and the second inner groove 16, and at the same time, the second inner groove 16 is arranged to prevent external dust from entering the first inner groove 4 and the second inner groove 16, and the shape of the exhaust hole 17 is arranged to prevent external moisture from penetrating.

[0026] According to the above working process, it can be known that: by inserting the positioning block 8 into the interior of the adjacent positioning groove 7 so that the temperature sensor body 5 can be placed at the inner cavity surface position of the first inner groove 4, and by wrapping the outside of the mounting seat 2 with two shells 12, and by rotating the threaded rod 13 so that the rubber pad 14 can contact the temperature sensor body 5, the heat-conducting block 6 connected to the temperature sensor body 5 can fit tightly against the inner circumferential surface of the first inner groove 4, so that the temperature sensor body 5 can fully detect the temperature, thereby the temperature sensor body 5 can be wrapped up to prevent the temperature sensor body 5 from being damaged by the infiltrated moisture, thereby improving the use stability of the temperature sensor body 5.

[0027] Further as Figure 3As shown, it is worth explaining in detail that the cross-section of the inner cavity of the positioning groove 7 is T-shaped, and the cross-section of the inner part of the surface of the positioning block 8 embedded in the adjacent position of the positioning groove 7 is T-shaped. Due to the shape of the inner cavity of the positioning groove 7 and the positioning block 8, the temperature sensor body 5 can be prevented from shaking in the vertical direction under the interference between the positioning block 8 and the inner cavity of the positioning groove 7, thereby improving the stability of the temperature sensor body 5.

[0028] In summary: by inserting the positioning block 8 into the interior of the adjacent positioning groove 7 so that the temperature sensor body 5 can be placed at the inner cavity surface position of the first inner groove 4, and by wrapping the outside of the mounting seat 2 with two shells 12, and by rotating the threaded rod 13 so that the rubber pad 14 can resist the temperature sensor body 5, the heat conductive block 6 connected to the temperature sensor body 5 can fit tightly against the inner circumferential surface of the first inner groove 4, so that the temperature sensor body 5 can fully detect the temperature, thereby the temperature sensor body 5 can be wrapped up to prevent the temperature sensor body 5 from being damaged by the infiltrated moisture, thereby improving the use stability of the temperature sensor body 5, and due to the shape setting of the inner cavity of the positioning groove 7 and the positioning block 8, the temperature sensor body 5 can be prevented from shaking in the vertical direction under the resistance of the positioning block 8 and the inner cavity of the positioning groove 7, thereby improving the stability of the temperature sensor body 5.

[0029] The temperature sensor body 5 can be purchased on the market. The temperature sensor body 5 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
