[0026] See also Figures 1 to 3 , Figures 1 to 3 A schematic diagram of a mounting structure 100 of an angle marker in an embodiment of the present application is shown. In some embodiments, the mounting structure 100 of the angle marker is used to mount the angle marker 200 to the crankcase of the engine to collect the speed signal of the engine.

[0027] In the present application, the angle marker 200 includes an angle marker body 201 and a fixing rod 202 connected to the angle marker body 201. The angle marker body 201 is used to collect the engine speed signal, and the fixing rod 202 is used to stabilize and support the angle marker body 201. The angle marker body 201 is usually cylindrical so as to be coaxially arranged with the engine pulley to ensure the accuracy of the measurement. The fixing rod 202 is arranged to extend radially along the angle marker body 201 and is connected to the circumferential surface of the angle marker body 201 so as to facilitate the connection between the angle marker body 201 and the installation structure 100 of the angle marker.

[0028] The installation structure 100 of the angle marker includes a fixed bracket 10, an adjustment unit 20 and an adapter unit 30. The fixed bracket 10 is configured to be connected to the crankcase of the engine to support and stabilize the angle marker 200. The adjustment unit 20 is adjustably connected to the fixed bracket 10, and the adjustment unit 20 is connected to the fixed rod 202 to adapt to different installation positions of the angle marker 200 and to be suitable for the installation of different angle markers 200. The adapter unit 30 includes a first adapter 31 and a second adapter 32, one end of the first adapter 31 is connected to the angle marker body 201, and the other end of the first adapter 31 is connected to the second adapter 32, and the second adapter 32 is used to connect the crankshaft pulley of the engine, and the first adapter 31, the second adapter 32, the crankshaft pulley and the angle marker body 201 are coaxially arranged.

[0029] Preferably, the outer circumference of the second adapter 32 is in contact with the inner side of the pulley. In order to ensure that the second adapter 32 is firmly and stably fixed, the outer circumference of the second adapter 32 can be optimized to a shape that matches the inner side of the pulley, so that the second adapter 32 can be stably in contact with the engine pulley, which is beneficial to improve the coaxiality of the angle marker body 201 and the engine pulley.

[0030] When installing the angle marker 200, the fixing bracket 10 can be first connected to the crankcase of the engine, the second adapter 32 can be connected to the crankshaft pulley of the engine, the first adapter 31 can be connected to the second adapter 32, and the angle marker body 201 can be connected to the first adapter 31. The first adapter 31, the second adapter 32, the crankshaft pulley and the angle marker body 201 are coaxially arranged, so that the angle marker 200 can maintain good coaxiality with the crankshaft, improve the measurement accuracy of the angle marker 200, and by adjusting the position of the adjustment unit 20, the fixing rod 202 of the angle marker 200 can be connected to the adjustment unit 20, so that the angle marker 200 can be stably supported by the bracket, and the installation stability and reliability of the angle marker 200 are improved. Further, the angle marker 200 installed by the installation structure 100 of the angle marker is not directly connected to the crankshaft pulley, which reduces the wear of the angle marker 200 and improves the service life of the angle marker 200.

[0031] In some embodiments, see Figures 1 to 3 The adjustment unit 20 includes a first adjustment member 21, which is connected to the fixed rod 202. The fixed bracket 10 is provided with a sliding groove 11. The first adjustment member 21 is disposed in the sliding groove 11 and can slide in the sliding groove 11, so that the first adjustment member 21 slides relative to the fixed bracket 10 to adjust the position of the angle marker 200. In other embodiments, the first adjustment member 21 can be rollably connected to the fixed bracket 10 to adjust the position of the angle marker 200. In another feasible embodiment, the fixed bracket 10 is provided with a bar hole, and the position of the angle marker 200 is adjusted by changing the position of the first adjustment member 21 in the bar hole.

[0032] Furthermore, the adjustment unit 20 also includes a first fastener 23, and the first adjustment member 21 includes a first abutting portion 211 and a second abutting portion 212, and the first abutting portion 211 and the second abutting portion 212 are respectively arranged above and below the sliding groove 11, and the first fastener 23 is used to connect the first abutting portion 211 and the second abutting portion 212, so that the first abutting portion 211 and the second abutting portion 212 are both abutted against the fixed bracket 10.

[0033] Specifically, the first adjusting member 21 is an I-shaped member as a whole, and the two ends of the first adjusting member 21 are a T-shaped first abutting portion 211 and a T-shaped second abutting portion 212, respectively. The first abutting portion 211 and the second abutting portion 212 abut against the upper end surface and the lower end surface of the fixed bracket 10, respectively, and the first abutting portion 211 and the second abutting portion 212 can slide relative to the fixed bracket 10, and the first fastener 23 connects the first abutting portion 211 and the second abutting portion 212, thereby ensuring the integrity and sliding stability of the first adjusting member 21. After the angle marker 200 moves to the preset position, the gap between the first abutting portion 211 and the second abutting portion 212 is reduced by tightening the first fastener 23, and the first abutting portion 211 and the second abutting portion 212 can apply force to the fixed bracket 10, so as to achieve the fixation of the first adjusting member 21.

[0034] In some embodiments, see Figures 1 to 3 The adjustment unit 20 further includes a second adjustment member 22 , which is rotatably connected to the first adjustment member 21 and is connected to the fixing rod 202 , so that the installation angle of the angle marker 200 can be adjusted through the second adjustment member 22 .

[0035] Optionally, the adjustment unit 20 also includes a rotating pin 24, and the first adjusting member 21 is provided with two first rotating holes not shown in the figure that are relatively arranged, and the second adjusting member 22 is provided with a second rotating hole not shown in the figure. The rotating pin 24 can be inserted into one of the first rotating holes, the second rotating hole and the other first rotating hole in sequence. The second adjusting member 22 is configured to rotate relative to the first adjusting member 21 through the rotating pin 24, and the rotation of the second adjusting member 22 drives the fixed rod 202 to rotate, thereby realizing the adjustment of the installation angle of the angle marker 200 to adapt to different installation angles of the angle marker 200.

[0036] Furthermore, a fixing hole not shown in the figure and a mounting hole connected to the fixing hole are formed on the second adjusting member 22. The adjusting unit 20 also includes a second fastener not shown in the figure. The fixing rod 202 can be inserted into the mounting hole and can move relative to the mounting hole, thereby further changing the position of the angle marker 200. The second fastener can be inserted into the fixing hole and fix the fixing rod 202, thereby fixing the angle marker 200 to ensure the stability and reliability of the angle marker 200 after installation, so that the angle marker body 201 will not rotate.

[0037] In some embodiments, see Figures 1 to 3 The installation structure 100 of the angle marker also includes a tensioning unit 40, which is connected to the side of the second adapter 32 away from the first adapter 31, and the tensioning unit 40 can abut against the inner side of the crankshaft pulley. The setting of the tensioning unit 40 can further fix the adapter unit 30 and the crankshaft pulley, thereby improving the installation stability of the adapter unit 30.

[0038] In practice, the tensioning unit 40 includes a tensioning member 41 and a driving member 42. The tensioning member 41 includes a first end 411 and a second end 412 that are arranged opposite to each other. The first end 411 is rotatably connected to the driving member 42, and the second end 412 is displaceably connected to the second adapter 32. The driving member 42 can move relative to the second adapter 32, so that the second end 412 can abut against the inner side of the crankshaft pulley, that is, the position of the second end 412 of the tensioning member 41 can be changed by changing the driving member 42, so that the abutment and fixation between the tensioning member 41 and the pulley is achieved. Furthermore, by changing the position of the second end 412, the tensioning member 41 can also be adapted to pulleys of different sizes, further improving the applicability of the installation structure 100 of the angle marker.

[0039] Specifically in this embodiment, the driving member 42 is arranged at the center of the second adapter 32, and a plurality of tensioning members 41 are arranged, each tensioning member 41 is connected to the driving member 42 and is arranged along the radial direction of the second adapter 32, so that the positions of the plurality of tensioning members 41 can be changed by moving one driving member 42, and the second ends 412 of the plurality of tensioning members 41 abut against different positions inside the pulley, thereby improving the connection stability between the tensioning unit 40 and the pulley. In other embodiments, different tensioning members 41 can be driven by different driving members 42, so that the second ends 412 of different tensioning members 41 abut against different positions inside the pulley.

[0040] Preferably, the tensioning unit 40 further includes a connecting block 43, which is used to connect the plurality of tensioning members 41. The connecting block 43 is disposed at the center of the second adapter 32, and the driving member 42 is disposed through the center of the connecting block 43 and the driving member 42 can change the position of the connecting block 43 relative to the second adapter 32, and this arrangement also helps to ensure the coaxiality between the angle marker 200 and the pulley.

[0041] Specifically in this embodiment, there are four tension members 41, and the angle between adjacent tension members 41 is 90 degrees, so that the four tension members 41 can abut against four different positions on the inner circumference of the pulley, so that the tension members 41 and the pulley can maintain stability. The driving member 42 can be a bolt, and the bolt is fastened to connect the connecting block 43 and the center of the second adapter 32. By turning the bolt, the position of the connecting block 43 can be changed.

[0042] Furthermore, the connecting block 43 is connected to the first end 411 of the tensioning member 41 through a rotating pin, a strip hole is provided on the second end 412 of the tensioning member 41, and a fixing pin is provided on the second adapter 32. The fixing pin is inserted through the strip hole, so that the tensioning member 41 and the second adapter 32 can be connected, and when the first end 411 of the tensioning member 41 moves, the second end 412 will move accordingly, and the position of the fixing pin relative to the strip hole changes. The setting structure is simple, the moving process is convenient and reliable, and it helps to simplify the installation process of the installation structure 100 of the angle marker.

[0043] In some embodiments, see Figures 1 to 3 The first adapter 31 includes a first flange 311, a column 313 and a second flange 312. The first flange 311 is connected to one end of the column 313, and the first flange 311 is used to connect the angle marker body 201. The second flange 312 is connected to the other end of the column 313, and the second flange 312 is used to connect the second adapter 32. The column 313, the first flange 311 and the second flange 312 are coaxially arranged. It is feasible that the angle marker body 201 is also provided with a flange structure, which helps to improve the connection strength between the first flange 311 and the angle marker body 201.

[0044] In this embodiment, the first flange 311 is connected to the angle marker body 201 by fasteners such as bolts, and the second flange 312 is connected to the second adapter 32 by fasteners such as bolts. The column 313 is provided so that a certain distance is provided between the first flange 311 and the second flange 312, which is convenient for inserting fasteners such as bolts, and for connecting the first adapter 31 with the angle marker body 201 and the second adapter 32.

[0045] Optionally, a central through hole is provided at the center of the column 313, and both ends of the central through hole are respectively connected to the central holes of the first flange 311 and the second flange 312. The arrangement of the central through hole and the central holes of the first flange 311 and the second flange 312 is conducive to reducing the deadweight of the first adapter 31 and avoiding the first adapter 31 from affecting the test data.

[0046] When the installation structure 100 of the angle marker in the present application is used, firstly, the fixing bracket 10 is connected to the suspension threaded hole of the engine crankcase through the fastener, then the first adapter 31 and the second adapter 32 are connected together through the fixing screws, and then the second adapter 32 is pressed against the inner side of the engine crankshaft pulley, and the driving member 42 is rotated to make the connecting block 43 move along the axial direction of the second adapter 32, and at the same time, the position of the tensioning member 41 is moved to abut against the inner circumference of the pulley, so as to complete the positioning between the adapter unit 30 and the pulley. Finally, the fixing rod 202 of the angle marker 200 is inserted into the installation hole of the second adjusting member 22, and the installation position of the angle marker 200 is adjusted by the first adjusting member 21, and the installation angle of the angle marker 200 is adjusted by the second adjusting member 22. After the angle marker body 201 moves to the preset position, the first adjusting member 21 and the fixing rod 202 are fixed, and the angle marker body 201 is connected to the first adapter 31 through the fasteners to complete the installation of the angle marker 200.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
