Abstract
Description
Technical Field
[0001] This utility model relates to an on-board sensor, specifically a gearbox speed sensor. Background Technology
[0002] The gearbox speed sensor is used to monitor the speed of the gearbox output shaft or output shaft, and it senses the speed through the Hall effect principle.
[0003] Existing speed sensors are designed with their external mounting structures primarily adapted to the shape and structure of the transmission and its mounting position on the vehicle body. This results in a limited applicability of a single transmission speed sensor, limiting its use to only one or a few similar vehicle models, making widespread application difficult. Utility Model Content
[0004] To address the technical problem that existing gearbox speed sensors are difficult to apply on a large scale, this invention provides a gearbox speed sensor with a variable mounting structure, enabling different sensor structures and thus expanding the sensor's applicability.
[0005] The technical solution of this utility model is:
[0006] A gearbox speed sensor, comprising:
[0007] The base has a mounting groove on its end face and an embedded area in the middle. The other end face of the base is a first inclined surface relative to the end face with the mounting groove. The inclined end of the base has two mutually perpendicular first threaded holes and second threaded holes. The base has multiple channels that pass through both ends.
[0008] A Hall sensor is disposed in the mounting slot, with its first pin located in the channel and placed on the first inclined surface of the base;
[0009] A connecting block having a third threaded hole on one side, and the connecting block having pin holes that match the channel;
[0010] The bolt can be fitted into the first threaded hole and the third threaded hole, or into the threaded hole and the third threaded hole;
[0011] The second pin is located inside the pin hole of the connecting block and contacts the first pin.
[0012] Optionally, the first inclined surface has an inclination angle of 45° relative to the base having one end face.
[0013] Optionally, the channel extends to the first inclined surface and extends along the inclined direction of the first inclined surface.
[0014] Optionally, the channel is provided with a guide plate, and the first pin and the second pin respectively abut against the two ends of the guide plate.
[0015] Optionally, there are at least two first threaded holes and two second threaded holes on the first inclined surface.
[0016] Optionally, one end face of the connecting block is also a second inclined surface, and the second inclined surface has the same inclination angle as the first inclined surface, with one end of the pin hole located on the second inclined surface.
[0017] Optionally, the second inclined surface also has an embedding groove, which is located at the end of the pin hole;
[0018] The embedded slot is provided with a connecting plate, which is connected to the second pin.
[0019] Optionally, the connecting plate includes a straight plate and an arc-shaped plate.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] The base is designed with a Hall sensor installed in the mounting groove on the end face of the base. The connecting block is then installed on the top surface of the base with bolts. Since the top surface of the base is inclined and has two mutually perpendicular threaded holes, the connecting block will extend in the inclined direction when it is installed on the top surface of the base. Furthermore, when the bolts on the connecting block engage with the two different threaded holes on the top of the base, the extension direction of the connecting block will have a certain angle difference, thus enabling the sensor to be in a switchable state, making it more practical.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example
[0033] See Figure 1 and Figure 2 This embodiment discloses a gearbox speed sensor, including a base 10, a Hall sensor 20, a connecting block 30, a bolt 40, and a second pin 50. The Hall sensor 20 is installed at the bottom of the base 10, the connecting block 30 is installed at the top of the base 10, and the second pin 50 is disposed on the connecting block 30. The first pin 21 of the Hall sensor 20 abuts against the second pin 50. The connecting block 30 and the base 10 are detachably connected by the bolt 40. Different structures of the gearbox speed sensor can be achieved by different connection methods between the base 10 and the connecting block 30, so as to achieve a wider range of applications.
[0034] Specifically, such as Figure 3 and Figure 5As shown, a mounting groove 11 is provided at the bottom of the base 10, and an embedded area 12 is provided in the middle of the base 10. The embedded area 12 is above and close to the mounting groove 11. The top of the base 10 is a first inclined surface 13, which is inclined relative to the bottom surface of the base 10.
[0035] The base 10 is also provided with a first threaded hole 14 and a second threaded hole 15, wherein the first threaded hole 14 extends along the length direction of the base 10, and the second threaded hole 15 extends along the length direction perpendicular to the base 10. In addition, a channel 16 is provided on the base 10 from its bottom end to its top end. There are multiple channels 16, and the number of channels 16 is the same as the number of the first pins 21 of the Hall sensor 20.
[0036] During installation, the Hall sensor 20 is positioned within the mounting slot 11, and its first pin 21 is positioned within the channel 16 and extends to the first inclined surface 13 of the base 10. A magnet is provided within the embedded area 12 of the base 10.
[0037] See Figure 6 The connecting block 30 has a third threaded hole 31 on one side, and a pin hole 32 matching the pin 16 is provided inside the connecting block 30. The pin hole 32 extends through both ends of the connecting block 30, and a second pin 50 is provided inside the pin hole 32. The number of pin holes 32 is equal to the number of first pins 21 of the Hall sensor 20, and one second pin 50 is provided in each pin hole 32. When the connecting block 30 is installed on the base 10, the second pins 50 are connected one-to-one with the first pins 21 of the Hall sensor 20.
[0038] In this embodiment, a base 10 is designed, and a Hall sensor 20 is installed in the mounting groove 11 on the end face of the base 10. Then, a connecting block 30 is installed on the top surface of the base 10 by bolts 40. Since the top surface of the base 10 is a first inclined surface 13 and has two mutually perpendicular first threaded holes 14 and second threaded holes 15, when the connecting block 30 is installed on the first inclined surface 13 of the base 10, the connecting block 30 will extend along the inclined direction. Furthermore, when the bolts 40 on the connecting block 30 (after passing through the threaded hole 32) cooperate with the two different first threaded holes 14 and second threaded holes 15 on the top of the base 10, there will be a certain angle difference in the extension direction of the connecting block 30, so that the structure of the sensor is in a switchable state, thus making it more practical.
[0039] In one specific embodiment:
[0040] The first inclined surface 13 at the top of the base 10 has an inclined angle of 45° relative to the bottom surface of the base 10. In addition, the channel 16 extends onto the first inclined surface 13 and extends along the inclined direction of the first inclined surface 13.
[0041] This design ensures that, regardless of the connection method between the connecting block 30 and the base 10, the second pin 50 can remain in contact with the first pin 21 of the Hall sensor 20.
[0042] Preferably, one end face of the connecting block 30 is also a second inclined surface 33, and the second inclined surface 33 has the same inclination angle as the first inclined surface 13. One end of the pin hole 32 is located on the second inclined surface 33. When the inclination angle 13 on the base 10 and the second inclined surface 33 on the connecting block 30 are in contact with each other, there exists Figure 1 and Figure 7 The two states shown are as follows: after the base 10 and the connecting block 30 are connected, the bolt 40 passes through the third threaded hole 31 and then engages with the first threaded hole 14, so that the connecting block 30 and the base 10 are distributed in a vertical state, making the speed sensor have an L-shaped structure. After the bolt 40 passes through the third threaded hole 31 and then engages with the second threaded hole 15, so that the connecting block 30 and the base 10 are distributed in a straight line, making the speed sensor have a straight structure.
[0043] Preferably, to ensure structural stability after the connecting block 30 and the base 10 are connected by bolts 40, two parallel first threaded holes 14 and two parallel second threaded holes 15 are provided on the base 10. Correspondingly, two parallel third threaded holes 31 are provided on the connecting block 30, and two bolts 40 are used for connection.
[0044] In another specific embodiment:
[0045] See Figure 2 The second inclined surface 33 also has an embedding groove 34, which is located at the end of the pin hole 32. A connecting plate 35 is provided inside the embedding groove 34, and the connecting plate 35 is connected to the second pin 50.
[0046] By setting the connecting plate 35, the end area of the second pin 50 can be increased. Thus, after the connecting block 30 is installed on the base 10, the area of the connecting plate 35 and the first pin 21 of the Hall sensor 20 can be increased, thereby ensuring the stability of the signal transmission of the Hall sensor 20.
[0047] Preferably, such as Figure 4As shown, the connecting plate 35 includes a straight plate 351 and an arc-shaped plate 352, and the arc-shaped plate 352 is elastic. Through this design, after the connecting block 30 is connected to the base 10, the elastic arc-shaped plate 352 enhances the contact stability between the connecting plate 35 and the first pin 21 of the Hall sensor 20, thus avoiding the problem of temporary disconnection between the connecting plate 35 and the first pin 21 of the Hall sensor 20 when the vehicle moves and vibrates.
[0048] In addition, such as Figure 3 and Figure 4 As shown, a guide plate 60 is provided in the channel 16. The first pin 21 and the second pin 50 respectively abut against the two ends of the guide plate 60. The guide plate 60 facilitates the replacement of the Hall sensor 20.
[0049] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
