Description

Technical Field

[0001] This utility model relates to the field of sensor shaft technology, specifically a robust and stable sensor shaft. Background Technology

[0002] The intermediate shaft sensor is a component that integrates sensor functions into the intermediate shaft. Different types of intermediate shaft sensors have different functions. For example, the intermediate shaft sensor is used to detect the rotational speed of the automatic transmission output shaft. The electronic control unit (ECU) calculates the vehicle speed based on the sensor signal, which serves as the basis for shift control, ensuring that the driver can stably control the vehicle speed. At the same time, by comparing the intermediate shaft gear speed signal (NC) and the direct drive clutch speed sensor signal (NT), the ECM can detect the gear shift timing and appropriately control the engine torque and hydraulic pressure according to various conditions to achieve a smooth shifting effect.

[0003] Traditional sensor shafts are typically installed using a single threaded connection. While this connection is simple and easy to implement, the bolts are prone to loosening under frequent vibrations and impacts, requiring regular inspection and tightening. This increases maintenance costs and workload, resulting in poor stability of the sensor shaft. Utility Model Content

[0004] The purpose of this invention is to provide a robust and stable sensor shaft, which solves the problem that traditional sensor shafts are usually installed using a single threaded connection. Although the threaded connection is simple and easy to implement, the bolts are prone to loosening under frequent vibration and impact, requiring regular inspection and tightening, which increases maintenance costs and workload, and consequently leads to poor robustness and stability of the sensor shaft.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a robust and stable sensor shaft, comprising a sensor shaft body. One end of the sensor shaft body is threadedly connected to a left mounting base, and the other end of the sensor shaft body is fixedly mounted to a right mounting base. The right mounting base has a groove inside, and a threaded groove inside the groove. An adjustment component is installed inside the groove. The bottom inner part of the right mounting base has several sliding grooves, and a reinforcing mechanism is installed inside each sliding groove. The reinforcing end of the reinforcing mechanism extends to the outer surface of the right mounting base, and the abutting end of the reinforcing mechanism abuts against the abutting end of the adjustment component.

[0007] Furthermore, the adjustment component includes a threaded tube, the groove has a threaded tube inside, the threaded tube and the threaded groove are threadedly connected, a hexagonal adjustment head is fixedly installed at one end of the threaded tube, and a first arc-shaped surface is opened at the other end of the threaded tube.

[0008] Furthermore, the reinforcement mechanism includes a slide rod, which is fixedly installed on the inner wall of the slide groove. A slider is slidably connected to the outer surface of the slide rod, and a spring is sleeved on the outer surface of the slide rod. One end of the spring is fixedly connected to the inner wall of the slide groove, and the other end of the spring is fixedly connected to the outer surface of the slider.

[0009] Furthermore, an abutment block is fixedly installed on the upper surface of the slider, and the abutment block is slidably connected inside the right mounting base and extends to the outer surface of the right mounting base.

[0010] Furthermore, the outer surface of the abutment block is provided with a second arc-shaped surface.

[0011] Furthermore, the second arc-shaped surface abuts against the hexagonal adjusting head.

[0012] Furthermore, the outer surface of the abutment block is provided with several anti-slip protrusions.

[0013] This utility model has the following beneficial effects:

[0014] (1) When the sensor central axis needs to be adjusted, the hexagonal adjustment head is rotated first. Since the threaded tube is connected to the threaded groove, rotating the hexagonal adjustment head will drive the threaded tube to move in the groove. The first arc surface at one end of the threaded tube and the second arc surface on the outer surface of the abutment block can fit tightly and slide smoothly during relative movement. As the threaded tube moves, it will push the abutment block. During the process of the threaded tube pushing the abutment block, the spring is stretched. The abutment block slides in the right mounting seat and extends to its outer surface. The abutment block extends to the outer surface of the right mounting seat and connects with the external connecting parts, which can achieve the effect of stable installation of the sensor central axis body, prevent it from loosening or shaking during operation, and ensure the normal operation and measurement accuracy of the sensor.

[0015] (2) By setting anti-slip protrusions, this utility model further enhances the friction between the abutment block and other components, prevents slippage during use, and ensures the reliability and stability of the entire structure.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, this utility model is a robust and stable sensor shaft, including a sensor shaft body 1. One end of the sensor shaft body 1 is threadedly connected to a left mounting seat 2, and the other end of the sensor shaft body 1 is fixedly mounted with a right mounting seat 3. The right mounting seat 3 has a groove 301 inside, and a threaded groove 302 inside the groove 301. An adjustment component 4 is installed inside the groove 301. Several sliding grooves 303 are opened at the bottom inner side of the right mounting seat 3. A reinforcing mechanism 5 is installed inside each sliding groove 303. The reinforcing end of the reinforcing mechanism 5 extends to the outer surface of the right mounting seat 3, and the abutting end of the reinforcing mechanism 5 abuts against the abutting end of the adjustment component 4.

[0027] Adjustment component 4 includes a threaded tube 401. The groove 301 is provided with a threaded tube 401 inside. The threaded tube 401 and the threaded groove 302 are threadedly connected. A hexagonal adjustment head 402 is fixedly installed at one end of the threaded tube 401. A first arc-shaped surface 403 is opened at the other end of the threaded tube 401.

[0028] The reinforcement mechanism 5 includes a slide rod 501, which is fixedly installed on the inner wall of the slide groove 303. A slider 502 is slidably connected to the outer surface of the slide rod 501. A spring 503 is sleeved on the outer surface of the slide rod 501. One end of the spring 503 is fixedly connected to the inner wall of the slide groove 303, and the other end of the spring 503 is fixedly connected to the outer surface of the slider 502.

[0029] A stop block 504 is fixedly installed on the upper surface of the slider 502. The stop block 504 is slidably connected to the inside of the right mounting base 3 and extends to the outer surface of the right mounting base 3.

[0030] The outer surface of the abutment block 504 is provided with a second arc-shaped surface 505;

[0031] The second arc-shaped surface 505 and the hexagonal adjusting head 402 abut against each other;

[0032] The outer surface of the abutment block 504 is equipped with several anti-slip protrusions 506;

[0033] When the sensor's central axis needs adjustment, first rotate the hexagonal adjustment head 402. Since the threaded tube 401 is threadedly connected to the threaded groove 302, rotating the hexagonal adjustment head 402 will cause the threaded tube 401 to move within the groove 301. The first arc-shaped surface 403 at one end of the threaded tube 401 and the second arc-shaped surface 505 on the outer surface of the abutment block 504 allow them to fit tightly and slide smoothly during relative movement. As the threaded tube 401 moves, it will push the abutment block 504. During the process of the threaded tube 401 pushing the abutment block 504, the spring 503 is stretched, and the abutment block 504 slides within the right mounting base 3 and extends to its outer surface. The abutment block 504 extends to the outer surface of the right mounting base 3 and connects with the external connector, thus achieving the effect of stable installation of the sensor's central axis body 1, preventing it from loosening or shaking during operation, and ensuring the normal operation and measurement accuracy of the sensor.

[0034] In use, first install the left mounting base 2 on one side of the external connector, then install the right mounting base 3 into the other side of the external connector, and the right mounting base 3 and the left mounting base 2 are threaded together to complete the fixed installation of the sensor central shaft body 1.

[0035] When the sensor's central axis needs adjustment, first rotate the hexagonal adjustment head 402. Since the threaded tube 401 is threadedly connected to the threaded groove 302, rotating the hexagonal adjustment head 402 will cause the threaded tube 401 to move within the groove 301. The first arc-shaped surface 403 at one end of the threaded tube 401 and the second arc-shaped surface 505 on the outer surface of the abutment block 504 allow them to fit tightly and slide smoothly during relative movement. As the threaded tube 401 moves, it will push the abutment block 504. During the process of the threaded tube 401 pushing the abutment block 504, the spring 503 is stretched, and the abutment block 504 slides within the right mounting base 3 and extends to its outer surface. The abutment block 504 extends to the outer surface of the right mounting base 3 and connects with the external connector, thus achieving the effect of stable installation of the sensor's central axis body 1, preventing it from loosening or shaking during operation, and ensuring the normal operation and measurement accuracy of the sensor.

[0036] The anti-slip protrusions 506 further enhance the friction between the abutment block 504 and other components, preventing slippage during use and ensuring the reliability and stability of the entire structure.

[0037] When the reinforcement mechanism 5 is not needed, the threaded tube 401 is unscrewed from the inside of the right mounting base 3. When the second arc-shaped surface 505 and the hexagonal adjusting head 402 are released from contact, the spring 503 rebounds, thereby resetting the abutment block 504. The operation is simple and convenient.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
