Description

Technical Field

[0001] This utility model relates to automotive parts, particularly to a continuously variable signal control panel for engines. Background Technology

[0002] The signal control panel is an important component of the automotive crankshaft position sensor, used to detect the crankshaft angle and engine speed.

[0003] During the replacement of the engine oil seal, the signal control plate needs to be removed from the crankshaft. After the oil seal is replaced, the crankshaft and signal control plate are then installed. During the installation of the signal control plate and the crankshaft, it is necessary to ensure that the signal control plate is aligned with the crankshaft, that is, the installation angle of the control plate and the crankshaft is unique.

[0004] The existing installation involves mounting the signal control disc on the crankshaft and then counting the signal teeth clockwise or counterclockwise. For example, in the BYD Surui 1.5T engine, there are 16 signal teeth between the center of the crankshaft sensor and the signal teeth. To avoid secondary adjustments after installation, maintenance personnel often remove the signal control disc after marking its relative position. However, the above operation is time-consuming and laborious, adding an extra marking step.

[0005] In summary, how to achieve rapid installation of the signal control panel has become an urgent problem for researchers in this field. Summary of the Invention

[0006] The technical problem to be solved by this utility model is: how to achieve rapid installation of the signal control panel;

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model is an engine continuously variable signal control disc, comprising: a disc body, wherein multiple signal teeth are arranged circumferentially around its edge; wherein, a tooth-missing portion is formed on both sides of two adjacent signal teeth, and a first tooth and a second tooth are distributed on both sides of the tooth-missing portion circumferentially; multiple mounting holes are equally spaced around the center of the disc body, wherein the center of one of the mounting holes is located on the first line connecting the first tooth to the center of the disc body.

[0009] In this design, the signal control disk has a sheet-like structure. Multiple signal teeth are arranged circumferentially along the edge of the disk body. Adjacent signal teeth are evenly spaced. The distance between the first and second teeth on both sides of the missing tooth section is greater than the distance between two adjacent signal teeth. When the signal control disk rotates to the point where the missing tooth section meets the sensor, the crankshaft is at its limit position. The multiple mounting holes on the disk body are used to connect the signal control disk to the crankshaft. The center of one mounting hole is located on the first line connecting the first tooth on the signal control disk to the center of the disk body.

[0010] During the installation of the signal control panel and crankshaft, the first tooth can be positioned by the location of one of the mounting holes, thereby positioning the missing tooth section. In other words, ensuring the accurate installation of the mounting hole position ensures the accurate installation of the missing tooth section, enabling rapid installation between the signal control panel and crankshaft.

[0011] Since the signal control panel is a sheet-like structure, to prevent the signal control panel from being installed backwards during the installation process, which could lead to inaccurate positioning of the missing teeth, this utility model adopts a tapered hole structure that is wider at the top and narrower at the bottom for the mounting hole.

[0012] The mounting holes are designed to be wider at the top and narrower at the bottom. Before installation, the position of the mounting holes must be determined first. The end closer to the wide opening of the mounting hole is the front of the signal control panel, and the end closer to the narrow opening is the back of the signal control panel. Determining the position of the mounting holes during installation can prevent the signal control panel from being installed backwards.

[0013] To further prevent the signal control panel from being installed backwards, this utility model employs a foolproof hole on the panel body, wherein the second line connecting the center of the foolproof hole to the center of the panel body is not collinear with the first line.

[0014] Anti-foolproof holes are also provided on the disc body. The line connecting the anti-foolproof hole and the center of the disc body is the second line. The angle between the first line and the second line is not 180°, but 105° in this solution. Corresponding anti-foolproof holes are also provided on the crankshaft end face. During the installation process, the two anti-foolproof holes overlap, which can ensure that the disc body is installed in an accurate position.

[0015] The beneficial effects of this utility model are as follows: This utility model is a continuously variable signal control disc for an engine. The signal control disc has a sheet-like structure, with multiple signal teeth arranged circumferentially along the edge of the disc body. Adjacent signal teeth are evenly spaced. The distance between the first and second teeth on both sides of the missing tooth section is greater than the distance between two adjacent signal teeth. When the signal control disc rotates to the point where the missing tooth section meets the sensor, the crankshaft is at its limit position. The multiple mounting holes on the disc body connect the signal control disc to the crankshaft. The center of one mounting hole is located on the first line connecting the first tooth on the signal control disc to the center of the disc body. During the installation of the signal control disc and the crankshaft, the first tooth can be positioned by the position of one of the mounting holes, thereby positioning the missing tooth section. That is, ensuring the accurate installation of the mounting hole position ensures the accurate installation of the missing tooth section, enabling rapid installation between the signal control disc and the crankshaft.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] like Figure 1-3 As shown, this utility model is an engine continuously variable signal control disc, comprising: a disc body 1, with a plurality of signal teeth 2 arranged circumferentially at its edge; wherein, a toothed portion 3 is formed on both sides of two adjacent signal teeth 2, and a first tooth 21 and a second tooth 22 are distributed on both sides of the toothed portion 3 circumferentially; a plurality of mounting holes 4, which are equally spaced around the center of the disc body 1, wherein the center of one of the mounting holes 4 is located on the first line 5 connecting the first tooth 21 to the center of the disc body 1.

[0023] In this design, the signal control disk has a sheet-like structure. Multiple signal teeth 2 are arranged circumferentially around the edge of the disk body 1. Adjacent signal teeth 2 are evenly spaced. The distance between the first tooth 21 and the second tooth 22 on both sides of the missing tooth section 3 is greater than the distance between two adjacent signal teeth 2. When the signal control disk rotates to the point where the missing tooth section 3 meets the sensor, the crankshaft is at its limit position. The function of the multiple mounting holes 4 on the disk body 1 is to connect the signal control disk to the crankshaft. The center of one mounting hole 4 is located on the first line 5 connecting the first tooth 21 on the signal control disk to the center of the disk body 1.

[0024] like Figure 2 As shown, during the installation of the signal control panel and crankshaft, the first tooth 21 can be positioned by the position of one of the mounting holes 4, thereby positioning the missing tooth part 3. That is, ensuring the accurate installation of the mounting hole 4 ensures the accurate installation of the missing tooth part 3, thus enabling rapid installation between the signal control panel and crankshaft.

[0025] Since the signal control panel is a sheet-like structure, to prevent the signal control panel from being installed backwards during the installation process, which could lead to inaccurate positioning of the missing teeth, this utility model adopts a tapered hole structure with a wider top and a narrower bottom for the mounting hole 4.

[0026] The mounting hole 4 is designed to be wider at the top and narrower at the bottom. Before installation, the position of the mounting hole should be determined first. That is, the end closer to the wide opening of the mounting hole is the front of the signal control panel, and the end closer to the narrow opening of the mounting hole is the back of the signal control panel. During the installation process, determining the position of the mounting hole 4 can prevent the signal control panel from being installed backwards.

[0027] like Figure 1 , 3 As shown, in order to further prevent the signal control panel from being installed backwards, the present invention employs a foolproof hole 6 on the panel body 1, and the second line 7 connecting the center of the foolproof hole 6 to the center of the panel body 1 is not collinear with the first line 5.

[0028] Anti-foolproof holes 6 are also provided on the disc body 1. The line connecting the anti-foolproof hole 6 and the center of the disc body 1 is the second line 7. The included angle between the first line 5 and the second line 7 is not 180°, but 105° in this solution. Corresponding anti-foolproof holes are also provided on the crankshaft end face. During the installation process, the two anti-foolproof holes 6 overlap, which can ensure that the disc body 1 is installed in an accurate position.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
