The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0028] In related technologies, the top dead center (TDC) sensor and the top dead center mechanical pointer are important components of low-speed diesel engines. The TDC sensor detects the rotation angle of the diesel engine crankshaft to determine the ignition timing of each cylinder, while the top dead center mechanical pointer is used for mechanical positioning at top dead center. Therefore, it is clear that the installation of both the TDC sensor and the top dead center mechanical pointer involves precision issues. To ensure accurate installation of both the TDC sensor and the top dead center mechanical pointer, they must first be positioned separately before installation, reducing installation efficiency.

[0029] To improve the installation and positioning efficiency of the top dead center sensor and the top dead center mechanical pointer, this application provides a combined mounting bracket for the top dead center sensor and the pointer. The combined mounting bracket includes: a bracket mounting structure for mounting the bracket onto a diesel engine; a sensor base structure disposed at a first end of the bracket mounting structure and located on a first side of the bracket mounting structure, with the first side of the sensor base structure and the first side of the bracket mounting structure forming a first preset angle, the sensor base structure being used to mount the top dead center sensor; and a top dead center pointer base structure disposed on a second side of the bracket mounting structure, the connection point between the second side of the bracket mounting structure and the second side of the sensor base structure contacting the second side of the top dead center pointer base structure, with the first side of the top dead center pointer base structure and the second side of the bracket mounting structure forming a second preset angle, and the second side of the top dead center pointer base structure and the second side of the sensor base structure forming a third preset angle, the top dead center pointer base structure being used to mount the top dead center mechanical pointer. By incorporating the sensor base structure and bracket mounting structure within the bracket mounting structure, the mounting bracket can simultaneously provide mounting positioning for both the top dead center sensor and the top dead center mechanical pointer. This effectively reduces the number of positioning operations, thereby significantly improving installation efficiency. Furthermore, since the top dead center pointer base structure can also be used for the top dead center mechanical pointer, it provides a mounting foundation for the pointer in addition to its positioning, eliminating the need for an additional bracket and effectively saving space occupied by such a bracket.

[0030] See Figures 1 to 3In this embodiment, the combined mounting bracket may include a bracket mounting structure 100, a sensor base structure 200, and a top dead center pointer base structure 300.

These second mounting holes 210 are disposed on the mounting surface of the sensor base structure 200 and located at the end of the sensor base structure 200 away from the bracket mounting structure 100. The second mounting holes 210 are rounded rectangles and can be used to mount a top-stop sensor. The plurality of second mounting holes 210 are based on a third side surface of the sensor base structure 200 (based on...).

[0038] In one embodiment, the top dead center pointer base structure 300 includes a top dead center mechanical pointer mounting structure, which is disposed on the mounting surface of the top dead center pointer base structure and located at one end of the top dead center pointer base structure 300 away from the bracket mounting structure 100.

[0040] In one embodiment, the top dead center mechanical pointer mounting structure may include multiple third mounting holes 310, each a strip-shaped through hole, which can be used to mount the top dead center mechanical pointer. Specifically, since the third mounting holes 310 are strip-shaped through holes, the top dead center mechanical pointer can be positioned through the third mounting holes 310, thereby quickly determining the required optimal alignment position and effectively improving ease of use. The multiple third mounting holes 310 are based on the third side surface of the top dead center pointer base structure 300 (based on...). Figure 1 In other words, the third side of the top dead center pointer base structure 300 is the side above the mounting surface of the top dead center pointer base structure 300, and is symmetrically set along the line of symmetry (i.e., Figure 1 The settings can be configured in the specified way (or asymmetrically), but no specific restrictions are made here.

[0041] In one embodiment, the top dead center mechanical pointer mounting structure may include a fourth mounting hole 320, a first sliding groove, a second sliding groove (neither the first nor the second sliding groove is shown in the figures), and a mounting bracket 330. The fourth mounting hole 320 is either rectangular or rounded rectangular. The first sliding groove is located on the same side of the fourth mounting hole 320 as the second side of the top dead center pointer base structure 300. The second sliding groove is located on the same side of the fourth mounting hole 320 as the first side of the top dead center pointer base structure 300.

The mounting bracket 330 can be used to mount the top dead center mechanical pointer. The mounting bracket includes a locking structure 331, which can be used to lock the mounting bracket 330 in the first and second sliding grooves. Specifically, the top dead center mechanical pointer can be mounted on the mounting bracket 330. The alignment position of the top dead center mechanical pointer is adjusted by sliding the mounting bracket 330 through the fourth mounting hole 320. Then, the position of the mounting bracket 330 is fixed by the locking structure, thus completing the alignment of the top dead center mechanical pointer and effectively improving ease of use. The locking structure 331 may include a locking plate that is pushed towards the sliding groove to make tight contact with the inside of the sliding groove, thereby locking the mounting bracket 330 through friction. The locking structure 331 may include a gear 332 with a knob and two toothed locking plates 333. Rotating the knob 332 can move the toothed locking plates 333 towards or away from the sliding groove. When the toothed locking plates 333 move towards the sliding groove and make tight contact with the inside of the sliding groove, the mounting bracket 330 is locked by the friction between the toothed locking plates 333 and the inside of the sliding groove, and so on. Specific details are not limited here.
