[0028] like Figure 1-5 As shown, in this embodiment, a tool for confirming the installation position of the sensor includes a pressure seat 71 and a point marking rod 73. The pressure seat 71 is made of a transparent material. A marking hole 72 is provided at the bottom of the pressure seat 71. The marking hole 72 extends to the top of the pressure seat 71. The point marking rod 73 is movably inserted from the top of the marking hole 72. The point marking rod 73 can be a marking pen. The point marking rod 73 can be raised and lowered in the marking hole 72. The bottom end of the point marking rod 73 is located above the bottom of the pressure seat 71. A connecting component 74 is provided on the point marking rod 73. The point marking rod 73 is connected to the pressure seat 71 up and down through two connecting components 74. Elastic connection, two connecting parts 74 are respectively located on the left and right sides of the point mark rod 73, and a positioning mark is provided at the bottom of the pressure seat 71, and the positioning mark matches the tongue piece on the steering wheel heating plate. The detection area of ​​the steering wheel heating plate is on the tongue piece. During use, the pressure seat 71 is pressed on the tongue piece, and the positioning mark is aligned with the outer edge of the tongue piece. Then, the point mark rod 73 is pressed so that the bottom end of the point mark rod 73 acts on the tongue piece and forms an installation position mark on the tongue piece. The point mark rod 73 is released, and the point mark rod 73 is driven to rise by connection comparison, and the point mark rod 73 is separated from the tongue piece. Finally, the pressure seat 71 is removed;

[0029] The connecting component 74 includes a connecting plate 741, a guide column 742 and a first spring 743. The guide column 742 is vertically inserted into the top of the pressure seat 71. The connecting plate 741 is fixedly arranged on the top of the guide column 742. The connecting plate 741 is fixedly connected to the point mark rod 73. The first spring 743 is located between the connecting plate 741 and the pressure seat 71. The two ends of the first spring 743 are respectively connected to the pressure seat 71 and the connecting plate 741. The first spring 743 is sleeved on the guide column 742.

[0030] The connecting component 74 further includes a limiting blind hole 744, which is disposed at the bottom of the pressing seat 71, and a limiting block 745 is disposed in the limiting blind hole 744, and the limiting block 745 is fixedly disposed at the bottom end of the guide column 742, and the limiting block 745 abuts against the top of the limiting blind hole 744;

[0031] The limit block 745 is made of rubber, which is soft and can reduce the impact force generated when the limit block 745 abuts against the top of the limit blind hole 744, thereby achieving buffering.

[0032] When the point mark rod 73 is pressed down, the guide column 742 and the limit block 745 are driven to drop synchronously through the glue-dispensing connecting plate 741, and the first spring 743 is deformed. After the point mark rod 73 is released, the elastic action of the spring 8415 causes the connecting plate 741 to rise and reset, and drives the point mark rod 73 to rise and reset, and at the same time, the limit block 745 abuts against the top of the limit blind hole 744 to achieve positioning;

[0033] A connecting ring 75 is coaxially sleeved on the point marking rod 73, and the connecting ring 75 is connected to the connecting component 74. The connecting ring 75 is fixedly arranged on the connecting plate 741. Three locking screws 76 and three positioning components 77 are arranged on the connecting ring 75. The three locking screws 76 and the three positioning components 77 are uniformly distributed circumferentially with the point marking rod 73 as the center. A gap is arranged between the point marking rod 73 and the connecting ring 75, and a gap is arranged between the point marking rod 73 and the inner wall of the marking hole 72. The locking screws 76 are screwed to the connecting ring 75. One end of the locking screw 76 abuts against the point mark rod 73, and the positioning component 77 is used to realize the horizontal positioning of the point mark rod 73 to ensure that the point mark rod 73 is coaxial with the marking hole 72. When the point mark rod 73 needs to be replaced, the locking screw 76 is loosened, the point mark rod 73 is removed, and the new point mark rod 73 is passed through the connecting ring 75 and inserted from the top of the marking hole 72. During this period, the point mark rod 73 is made coaxial with the marking hole 72 by the positioning component 77, and then the locking screw 76 is tightened to make the point mark rod 73 and the connecting ring 75 achieve a relatively static position relationship.

[0034] The positioning component 77 includes a positioning plate 771, a moving rod 772 and a second spring 773. The moving rod 772 passes horizontally through the connecting ring 75. The moving rod 772 is slidably connected to the connecting ring 75 along the length direction of the moving rod 772. The axis of the moving rod 772 is perpendicular to and intersects with the axis of the marking hole 72. The positioning plate 771 is located in the ring hole of the connecting ring 75. The side of the positioning plate 771 close to the axis of the marking hole 72 abuts against the point marking rod 73. One end of the moving rod 772 is fixedly set on the other side of the positioning plate 771. The second spring 773 is sleeved on the moving rod 772. The second spring 773 is located on the outer side of the connecting ring 75. One end of the second spring 773 is connected to the connecting ring 75, and the other end of the second spring 773 is connected to the end of the moving rod 772 away from the positioning plate 771.

[0035] The top of the positioning plate 771 on the side close to the axis of the marking hole 72 is provided with a chamfer;

[0036] The moving rod 772 is a rectangular parallelepiped;

[0037] When the new dot marker rod 73 passes through the connecting ring 75, it pushes the positioning plate 771, so that the positioning plate 771 drives the moving rod 772 to move in the direction away from the axis of the marking hole 72, and the second spring 773 is stretched. Through the elastic action of the second spring 773, each positioning plate 771 positions the dot marker rod 73, ensuring that the dot marker rod 73 is coaxial with the marking hole 72, which is convenient for improving the accuracy of the dot marker rod 73 acting on the tongue piece, and is also suitable for dispensing pens of different diameters.

[0038] To summarize, by pressing the pressure seat 71 onto the tongue piece and aligning the positioning mark with the outer edge of the tongue piece, and then pressing the point mark rod 73 so that the bottom end of the point mark rod 73 acts on the tongue piece and forms an installation position mark on the tongue piece, it is convenient to locate the installation position of the temperature sensor and improve the installation accuracy of the temperature sensor.

[0039] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
