Description

Technical Field

[0001] This utility model relates to the field of crankshaft position sensor technology, and in particular to a crankshaft position sensor that is easy to adjust. Background Technology

[0002] The function of the crankshaft position sensor is to determine the position of the crankshaft, that is, the crankshaft angle and the engine speed. The crankshaft position sensor is usually installed at the front end of the crankshaft, the rear end of the crankshaft near the flywheel, or in the middle of the crankshaft. In early models, it was also installed inside the distributor. It is one of the most important sensors in the control system.

[0003] Existing crankshaft position sensors are used by inserting the sensor body into the engine housing and then fixing it with bolts through preset holes on the sensor. However, the preset holes are in fixed positions, resulting in poor versatility and reduced practicality. Utility Model Content

[0004] The main purpose of this invention is to provide a crankshaft position sensor that is easy to adjust.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] An easily adjustable crankshaft position sensor includes a body, a mounting base fixed on the body, a slot on the mounting base away from the body, a fixing sleeve inside the slot, an adjustment component outside the fixing sleeve, the adjustment component including guide grooves symmetrically formed on the mounting base, a guide seat slidably connected in the guide groove, a connecting seat fixed on the mounting base away from the body, and an adjustment screw rotatably connected to the connecting seat.

[0007] Preferably, the body includes a protective sleeve, a detection probe, and a sleeve, and both the protective sleeve and the sleeve are made of rubber.

[0008] Preferably, the detection probe penetrates the protective sleeve, and the bottom end of the detection probe is located below the bottom end of the protective sleeve.

[0009] Preferably, the diameter of the mounting base is larger than the diameter of the protective sleeve, and the diameter of the mounting base gradually decreases from one end to the other.

[0010] Preferably, the mounting base has a threaded groove that matches the adjusting screw.

[0011] Preferably, a sealing sleeve is fixed at the connection between the outer side of the protective sleeve and the mounting base.

[0012] Preferably, a connecting wire is provided inside the sleeve, and the connecting wire is electrically connected to the detection probe.

[0013] The beneficial effects of this technology are:

[0014] By setting up a slot, a fixed sleeve, and an adjustment assembly, when installing the crankshaft position sensor, the operator can use the adjusting screw in the adjustment assembly according to the position of the mounting hole on the housing. The adjustment screw rotates along the mounting base, which drives the fixed sleeve and guide seat to move horizontally along the guide groove through the connecting seat, thereby adjusting the horizontal position of the fixed sleeve. It has strong versatility, meets the usage requirements, and improves practicality. Attached Figure Description

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown, this embodiment provides a crankshaft position sensor that is easy to adjust, including a body 1. A mounting base 2 is fixed on the body 1. The mounting base 2 can limit the length of the sensor entering the housing. A slot 3 is provided on the side of the mounting base 2 away from the body 1. The slot 3 facilitates the movement of the fixing sleeve 4. The fixing sleeve 4 is provided in the slot 3. The operator can use bolts to fix the sensor to the housing through the fixing sleeve 4. An adjustment component 5 is provided on the outside of the fixing sleeve 4. The adjustment component 5 includes guide grooves 501 symmetrically opened on the mounting base 2. The guide grooves 501 can guide the guide seat 502. The guide seat 502 is slidably connected in the guide grooves 501. The guide seat 502 can ensure the stability of the fixing sleeve 4 when it moves. A connecting seat 503 is fixed on the side of the mounting base 2 away from the body 1. The connecting seat 503 can connect the adjusting screw 504 and the fixing sleeve 4. The adjusting screw 504 is rotatably connected to the connecting seat 503. The adjusting screw 504 can adjust the horizontal position of the fixing sleeve 4.

[0022] like Figures 1-2 As shown, the main body 1 includes a protective sleeve 101, a detection probe 102, and a sleeve 103. Both the protective sleeve 101 and the sleeve 103 are made of rubber, which can ensure the stability of the sensor when inserted into the housing through the protective sleeve 101.

[0023] like Figures 1-2 As shown, the detection probe 102 penetrates the protective sleeve 101, and the bottom end of the detection probe 102 is located below the bottom end of the protective sleeve 101, so that the detection probe 102 can be protected by the protective sleeve 101. The engine speed can be detected by the detection probe 102.

[0024] like Figures 1-2 As shown, the diameter of the mounting base 2 is larger than the diameter of the protective sleeve 101, and the diameter of the mounting base 2 gradually decreases from one end to the other, which facilitates the sensor to be fixed on the housing through the mounting base 2.

[0025] like Figures 1-2 As shown, the mounting base 2 has a threaded groove that matches the adjusting screw 504, which facilitates the support and limiting of the adjusting screw 504 through the mounting base 2.

[0026] like Figures 1-2 As shown, a sealing sleeve 7 is fixed at the connection between the outer side of the protective sleeve 101 and the mounting base 2, which can ensure the sealing of the connection between the sensor and the housing.

[0027] like Figures 1-2 As shown, a connecting wire 6 is provided inside the sleeve 103, and the connecting wire 6 is electrically connected to the detection probe 102, so that it can be connected to the vehicle power supply line through the connecting wire 6, thereby enabling the sensor to be powered on and working.

[0028] The working principle of this device is as follows: When using this device, the operator uses the adjusting screw 504 in the adjusting assembly 5 according to the position of the mounting hole on the outer shell. The adjusting screw 504 rotates along the mounting base 2, which drives the fixing sleeve 4 and the guide seat 502 to move horizontally along the guide groove 501 through the connecting seat 503, thereby adjusting the horizontal position of the fixing sleeve 4. It has strong versatility, meets the usage requirements, and improves practicality. After the adjustment is completed, the operator uses bolts to fix the mounting base 2 to the outer shell through the fixing sleeve 4. At this time, the protective sleeve 101 and the detection probe 102 enter the outer shell and are connected to the vehicle power supply line through the connecting wire 6, thereby energizing the sensor to work. During the operation, the detection probe 102 detects the engine speed, and the sealing sleeve 7 can ensure the sealing of the connection between the sensor and the outer shell.

[0029] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
