Description

Technical Field

[0001] This application belongs to the field of transmission control technology, and in particular relates to a mounting component, a sensing unit, and a transmission control unit. Background Technology

[0002] A transmission control unit typically includes a controller and one or more sensors (such as pressure sensors) connected to the controller. The controller can determine the operating status of the transmission based on the data monitored by the sensors, and then control the transmission.

[0003] Currently, the SMP132 sensor is a commonly used sensor in transmission control units. When an SMP132 sensor fails and needs replacement, due to the limitations of its installation location, it can usually only be replaced with a new SMP132 sensor; other sensor models (such as the SMP142 sensor) cannot be directly installed. However, if SMP132 sensors are not available in a timely manner, it will prolong the sensor replacement time. Furthermore, if the SMP132 sensor is discontinued, the sensor mounting structure in the transmission control unit will need to be changed, which will significantly increase the replacement cost. Utility Model Content

[0004] This application provides an mounting component, a sensing unit, and a transmission control unit to solve the technical problem of replacing the SMP132 sensor with the SMP142 sensor.

[0005] According to one aspect of this application, a mounting member is provided for mounting a sensor and includes: a main body having a through hole; and an extension protruding from the main body along the axial direction of the through hole, wherein the extension and the main body together form a limiting groove, the limiting groove being configured to accommodate at least a portion of the sensor.

[0006] In an optional embodiment of this application, the extension is provided with at least one positioning opening, each positioning opening communicating with a limiting groove, and at least one of the positioning openings is configured to accommodate a sensor to constrain the rotation of the sensor relative to the limiting groove.

[0007] In an optional embodiment of this application, there are multiple positioning openings, and the extension includes multiple extension walls spaced circumferentially along the through hole, with two adjacent extension walls spaced apart to form a positioning opening.

[0008] In an optional embodiment of this application, there is one positioning opening, and the extension is a non-closed ring structure extending circumferentially along the through hole, with the beginning and end ends of the extension spaced apart to form the positioning opening.

[0009] In an optional embodiment of this application, the extension has a positioning protrusion on the side opposite to the limiting groove in its thickness direction. The positioning protrusion protrudes from the extension and is configured to cooperate with the fixing structure used to install the sensor, so as to constrain the rotation of the sensor relative to the fixing structure.

[0010] In an optional embodiment of this application, the positioning protrusion and the positioning opening are offset radially from each other in the through hole.

[0011] In an optional embodiment of this application, the surface of the extension away from the limiting groove in its thickness direction is coplanar with the surface of the main body away from the through hole.

[0012] In an optional embodiment of this application, the inner wall of the limiting groove is configured to be interference-fitted with the sensor.

[0013] According to another aspect of this application, a sensing unit is provided, which includes a sensor and the aforementioned mounting member, wherein at least a portion of the sensor is disposed in a limiting groove.

[0014] In an optional embodiment of this application, the sensor includes: a body portion disposed in a limiting groove; and a positioning portion protruding from the outer peripheral surface of the body portion, wherein at least a portion of the positioning portion is received in a positioning opening to constrain the rotation of the sensor relative to the mounting member.

[0015] According to another aspect of this application, a transmission control unit is provided, which includes a fixing structure and the aforementioned sensing unit, wherein the fixing structure is provided with a mounting groove and the sensing unit is mounted in the mounting groove.

[0016] In summary, the mounting component, sensing unit, and transmission control unit provided in this application have at least the following beneficial effects:

[0017] When the required normal sensor differs in size and / or shape from the faulty sensor that needs to be replaced, the mounting component of this application can be used to install the normal sensor into the original mounting position of the faulty sensor. Specifically, the normal sensor is first placed in the limiting groove of the mounting component, and then both are installed together into the original mounting position of the faulty sensor. Once the normal sensor is placed in the limiting groove of the mounting component, the main body of the mounting component can increase the thickness of the sensor, and the extension can increase the diameter of the sensor. Therefore, when the original sensor fails and a new sensor of the same type is unavailable or discontinued, the normal sensor can be used to replace the faulty sensor promptly. This achieves the replacement of the normal sensor with the faulty sensor, saving sensor replacement time. Furthermore, since it does not require a fixing structure for installing the sensor, it greatly reduces the sensor replacement cost. Attached Figure Description

[0028] To make the above and other features and advantages of this application clearer, the present invention will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art and are exemplary only, not restrictive.

[0029] Furthermore, features specified with "first" or "second" for descriptive purposes only should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features specified with "first" or "second" may explicitly or implicitly include at least one of the specified features. The description of "multiple" generally means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] Figure 1 This is a schematic diagram of the structure of the transmission control unit provided in this application. Figure 2A schematic diagram of the fixed structure provided in this application.

[0031] Reference Figure 1 and Figure 2 The transmission control unit 1000 provided in this application includes a fixed structure 200 and a sensing unit 100 mounted on the fixed structure 200. The fixed structure 200 is provided with a mounting groove 210 for mounting the sensing unit 100. The sensing unit 100 includes a sensor 20 and a mounting member 10. The sensor 20 is mounted in the mounting groove 210 of the fixed structure 200 through the mounting member 10.

[0032] Based on the structural design of the mounting component 10 and its cooperation with the sensor 20, the external shape and size of the sensor 20 can be changed. This allows the sensor 20 to be installed in the original mounting position of the faulty sensor even when its size and / or shape differs from the faulty sensor that needs to be replaced. In other words, the sensing unit 100 of this application can be installed in the same mounting slot 210 as the faulty sensor.

[0033] Therefore, when the supply of the original type of sensor is untimely or production is discontinued, the sensing unit 100 of this application can be used to replace the faulty sensor at its original installation location, thereby saving the sensor replacement time. Furthermore, since it does not require replacement of the fixing structure 200 in the transmission control unit 1000, the sensor replacement cost is greatly reduced.

[0034] For example, the description will be conducted using an SMP132 sensor as the faulty sensor and an SMP142 sensor as the sensor 20 in this application. Since the size (diameter and thickness) of the SMP142 sensor is smaller than that of the SMP132 sensor, when replacing the faulty SMP132 sensor with the SMP142 sensor, the SMP142 sensor can be installed in the original installation position of the faulty SMP132 sensor based on the fit between the SMP142 sensor and the mounting part 10, thereby realizing the replacement between the SMP142 sensor and the SMP132 sensor.

[0035] Understandably, the cross-sectional shape of the mounting groove 210 of the fixed structure 200 can be similar to the structural shape of the original sensor, and the structural shape of the mounting component 10 of this application can be similar to the cross-sectional shape of the mounting groove 210 of the fixed structure 200, thereby enabling the sensor 20 to be installed in the mounting groove 210 through the mounting component 10.

[0036] Specifically, the mounting groove 210 can be a circular mounting groove. Furthermore, in order to limit the installation of the sensing unit 100, the mounting groove 210 of the fixing structure 200 can also include an interconnected mounting groove segment 211 and a limiting groove segment 212. The limiting groove segment 212 cooperates with the mounting groove segment 211 to accommodate different parts of the sensing unit 100, thereby limiting the installation orientation and angle of the sensing unit 100 in the mounting groove 210.

[0037] To prevent vibration of the sensing unit 100 during daily use, the mounting part 10 of the sensing unit 100 can be interference-fitted with the mounting groove section 211 of the mounting groove 210. Since the interference fit is a tight fit, it can effectively fix the sensing unit 100, so that there will be no relative movement between the sensing unit 100 and the fixed structure 200 during daily use, thus avoiding inaccurate monitoring data of the sensor 20 and poor connection with other components caused by vibration of the sensing unit 100.

[0038] Furthermore, the transmission control unit 1000 provided in this application also includes a controller (not shown), which is connected to the sensor 20 of the sensing unit 100 and is used to determine the operating state of the transmission based on the data monitored by the sensor 20, thereby controlling the operation of the transmission.

[0039] The sensor 20 of the sensing unit 100 may include a body portion 21 and a positioning portion 22 protruding from the outer peripheral surface of the body portion 21. The body portion 21 is the core functional part of the sensor 20, which can be used to set pin structures with different functions for monitoring and data transmission. The positioning portion 22 is an auxiliary mounting part of the sensor 20, which mainly plays a positioning role during the installation process. It can cooperate with the corresponding part of the mounting member 10 to limit the mounting orientation and angle of the sensor 20 in the limiting groove B.

[0040] Figure 3 A perspective view of the installation component provided in this application. Figure 4 Another perspective view of the installation component provided in this application.

[0041] Reference Figure 3 and Figure 4 The mounting part 10 of the sensing unit 100 includes a main body 11 and an extension 12. The main body 11 is provided with a through hole A. The extension 12 protrudes from the main body 11 along the axial direction of the through hole A, and the extension 12 and the main body 11 together form a limiting groove B. The limiting groove B is configured to accommodate at least a portion of the sensor 20.

[0042] The through-hole A allows a portion of the pins of the sensor 20 to extend out of the mounting member 10, enabling electrical connection with external controllers and other components. Furthermore, the through-hole A effectively saves material usage in the mounting member 10. For example, the through-hole A may be located in the middle of the main body 11, and its cross-sectional shape may be circular.

[0043] The limiting groove B is formed by the main body 11 and the extension 12. The bottom wall of the limiting groove B is the main body 11, and the side wall is the extension 12, for accommodating at least a portion of the sensor 20. The shape of the limiting groove B can be determined according to the structural shape of the sensor 20. Specifically, the limiting groove B can be a limiting groove with a circular cross-section.

[0044] When sensor 20 differs in size and / or shape from the faulty sensor that needs to be replaced, and sensor 20 is required to replace the faulty sensor, the mounting part 10 of this application can be used for installation. Specifically, sensor 20 is first placed in the limiting groove B of the mounting part 10, and then both are installed together in the original mounting position of the faulty sensor. After sensor 20 is placed in the limiting groove B of the mounting part 10, since the main body 11 of the mounting part 10 can increase the thickness of sensor 20, and the extension 12 can increase the diameter of sensor 20, sensor 20 can be used to replace the faulty sensor promptly when the original sensor fails and a new sensor of the same type is unavailable or discontinued. This achieves the replacement of sensor 20 with the faulty sensor, saving sensor replacement time. Furthermore, since it does not require replacing the fixing structure 200 in the transmission control unit 1000, the sensor replacement cost is greatly reduced.

[0045] Again, let's take the example of an SMP132 sensor as the faulty sensor and an SMP142 sensor as the sensor 20 in this application. Since the size (diameter and thickness) of the SMP142 sensor is smaller than that of the SMP132 sensor, when it is necessary to replace the faulty SMP132 sensor with the SMP142 sensor, the SMP142 sensor can be placed in the limiting groove B of the mounting part 10 first, and then both can be installed together in the original mounting position of the faulty SMP132 sensor. When the SMP142 sensor is placed in the limiting groove B of the mounting part 10, the overall size and shape of the two are basically consistent with the size and shape of the faulty sensor that needs to be replaced. Therefore, when the original SMP132 sensor fails and the supply of a new SMP132 sensor is not timely or production is stopped, the SMP142 sensor can be used to replace the faulty SMP132 sensor in a timely manner. This realizes the replacement between the normal SMP142 sensor and the faulty SMP132 sensor, thereby saving sensor replacement time. Furthermore, since it does not require the replacement of the fixed structure 200 in the transmission control unit 1000, the sensor replacement cost is greatly reduced.

[0046] Reference Figure 3 and Figure 4 The extension 12 is provided with at least one positioning opening C, each positioning opening C is connected to the limiting groove B, and at least one of the positioning openings C is configured to accommodate a portion of the sensor 20 to constrain the rotation of the sensor 20 relative to the limiting groove B.

[0047] After the sensor 20 is installed on the mounting member 10, the body part 21 of the sensor 20 is located in the limiting groove B, and at least part of the positioning part 22 is received in the positioning opening C. Therefore, based on the orientation and angle of the positioning opening C relative to the limiting groove B, the orientation and angle of the sensor 20 relative to the mounting member 10 can be determined, thereby significantly improving the installation accuracy between the sensor 20 and the mounting member 10.

[0048] Specifically, the positioning opening C is a notch structure that penetrates the extension 12 along the thickness direction of the extension 12. After the sensor 20 is installed on the mounting member 10, the positioning part 22 can be completely accommodated in the positioning opening C. At this time, the length of the positioning part 22 in the radial direction of the through hole A can be less than or equal to the thickness of the extension 12 in that radial direction. Of course, the positioning part 22 can also be partially accommodated in the positioning opening C. At this time, the length of the positioning part 22 in the radial direction of the through hole A is greater than the thickness of the extension 12 in that radial direction. That is, part of the positioning part 22 extends out of the outside of the positioning opening C. The part of the positioning part 22 that extends out of the outside of the positioning opening C can cooperate with the limiting groove segment 212 of the mounting groove 210 of the fixing structure 200 to perform limiting installation.

[0049] To reduce vibration of the sensor 20 during actual use, the sidewall of the limiting groove B is configured to be interference-fitted with the body portion 21 of the sensor 20. In other words, the extension portion 12 is configured to be interference-fitted with the body portion 21 of the sensor 20.

[0050] In some embodiments, there are multiple positioning openings C, and the extension 12 includes multiple extension walls 121 spaced circumferentially along the through hole A. Two adjacent extension walls 121 are spaced apart to form a positioning opening C, such as... Figure 3 As shown.

[0051] In this embodiment, one of the positioning openings C can be selected as the target positioning opening for receiving the positioning part 22 of the sensor 20 and cooperating with the positioning part 22. This not only increases the installation flexibility between the sensor 20 and the mounting part 10, but also greatly reduces the material used in the mounting part 10.

[0052] Each extension wall 121, as part of the sidewall of the limiting groove B, can be configured to interfere with the body 21 of the sensor 20. Since the interference fit is a tight fit, the body 21 of the sensor 20 can be clamped by multiple extension walls 121, thereby reducing the vibration of the sensor 20 during actual use.

[0053] In other embodiments, there is one positioning opening C, and the extension 12 is a non-closed ring structure extending circumferentially along the through hole A. The two ends of the extension 12 are spaced apart to form the positioning opening C, such as... Figure 4 As shown.

[0054] In this embodiment, since the extension 12 is a non-closed ring structure with spaced intervals at both ends, it provides excellent circumferential coverage of the sensor 20's body 21, thereby better protecting the sensor 20 and reducing damage caused by external components. The extension 12 is a one-piece structure that serves as the sidewall of the limiting groove B, and it is configured to allow for an interference fit with the sensor 20's body 21. Similarly, because the sensor 20's body 21 can be surrounded and tightly enclosed by the extension 12, vibration of the sensor 20 during actual use can be reduced.

[0055] Reference Figure 3 The extension 12 has a positioning protrusion 13 on the side away from the limiting groove B in its thickness direction. The positioning protrusion 13 protrudes from the extension 12 and is configured to cooperate with the limiting groove segment 212 of the mounting groove 210 on the fixing structure 200 to position and install the sensing unit 100 and constrain the rotation of the mounting member 10 relative to the mounting groove 210, thereby constraining the rotation of the sensor 20 relative to the mounting groove 210.

[0056] After the sensing unit 100 is installed on the fixed structure 200, the main body 11 and the extension 12 of the mounting member 10 are both located in the mounting groove 211, and at least a portion of the positioning protrusion 13 is received in the limiting groove 212. Therefore, based on the orientation and angle of the limiting groove 212 relative to the mounting groove 211, the orientation and angle at which the sensing unit 100 needs to be installed relative to the fixed structure 200 can be determined, thereby significantly improving the installation accuracy between the sensing unit 100 and the fixed structure 200. At the same time, based on the stopping and limiting effect of the sidewall of the limiting groove 212 on the positioning protrusion 13 of the mounting member 10, the mounting member 10 and the sensor 20 on it will not rotate relative to the mounting groove 210 during actual use.

[0057] In some embodiments, the positioning protrusion 13 and the positioning opening C can be radially offset from each other in the through hole A, that is, the center line of symmetry of the positioning protrusion 13 and the center line of symmetry of the positioning opening C are not on the same straight line. This arrangement can ensure the overall structural strength of the mounting component 10.

[0058] In some embodiments, the surface of the extension 12 facing away from the limiting groove B in its thickness direction is coplanar with the surface of the main body 11 facing away from the through hole A. That is, the extension 12 is disposed on the outer edge of the main body 11 relative to the through hole A, so that the outer peripheral surfaces of the extension 12 and the main body 11 can have the same installation clearance with the inner wall of the mounting groove section 211 of the mounting groove 210, or the two can be interference-fitted together with the inner wall of the mounting groove section 211 of the mounting groove 210.

[0059] Based on the interference fit between the extension 12 and the main body 11 and the inner wall of the mounting groove 211, the sensing unit 100 can be firmly fixed in the mounting groove 211, thereby effectively reducing the vibration of the sensing unit 100 as a whole during actual use, and thus effectively reducing the vibration of the sensor 20 during actual use.

[0060] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
