Description
Technical Field
[0001] The utility model relates to the technical field of automobile component structures, in particular to a sensor and a reduction box. Background Art
[0002] The traditional method of measuring gearbox temperature is mainly to test it through a wired temperature sensor.

DETAILED DESCRIPTION
[0059] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.
[0060] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed at will, and the component layout may also be more complex.
[0061] Figure 1 It is a structural diagram of a sensor in related technology. Figure 1As shown, the reduction gearbox temperature measurement method in the related art is mainly tested by a wired temperature sensor. The temperature probe is fixed to the reduction gearbox cavity and connected to the temperature acquisition device of the whole vehicle through a wiring harness to obtain the temperature information inside the reduction gearbox.
[0062] Therefore, the sensors in the related art have at least the following defects: 1. The temperature change is mainly reflected by the change of the resistance value in the measurement circuit. In the actual test circuit, in addition to considering the resistance value of the thermistor, the influence of the wire resistance also needs to be considered. Due to the limitations of the processing technology, the temperature measurement accuracy is greatly affected by external interference; 2. During use, it is necessary to consider the fixing method, protection method, electromagnetic interference and other issues of the wiring harness. At the same time, it is also necessary to consider the selection of plug-ins and terminals, and their impact on the measurement results. The corresponding wiring harness and plug-ins also have a great impact on the cost of the sensor.
[0063] Figure 2 Schematic diagram of the structure of the sensor 100 provided in the embodiment of the present utility model. Figure 2 As shown, the present invention provides a sensor 100 comprising a housing 2, a collection module, and a signal transmission module. The housing 2 has a housing chamber 211; the collection module is configured to collect environmental information; and the signal transmission module is electrically connected to the collection module and configured to transmit the environmental information. The collection module and the signal transmission module are arranged parallel to each other within the housing chamber 211.
[0064] It is worth noting that the sensor 100 has an electrically connected signal transmission module and an acquisition module. The signal transmission through the signal transmission module can reduce the use of wiring harnesses, thereby reducing the overall weight of the vehicle and improving detection accuracy. At the same time, the acquisition module and the signal transmission module are arranged in parallel, which can effectively utilize the space of the accommodating chamber 211 and avoid space waste, making the design of the sensor 100 more compact, thereby helping to reduce the overall volume of the sensor 100 and facilitating installation and use in various narrow spaces. In addition, since the acquisition module and the signal transmission module are arranged in the same plane or in parallel positions, the complexity of the electrical connection path is reduced, which may improve the stability of signal transmission and reduce the risk of signal attenuation or interference.
[0065] Please refer to Figure 3 、 Figure 7 、 Figure 8 and Figure 9 The sensor 100 further includes a bracket 4 , on which the acquisition module and the signal transmission module are both mounted. The bracket 4 is located in the accommodating chamber 211 , and the bracket 4 abuts against the housing 2 .
[0066] In this embodiment, the bracket 4 includes a bracket body 41 and an elastic part 42 with elastic deformation capability. The acquisition module and the signal transmission module are both installed in the limiting chamber 48 of the bracket body 41. The elastic part 42 is connected to the bracket body 41, and the elastic part 42 is in contact with the shell 2.
[0067] Meanwhile, the acquisition module includes an acquisition mainboard 8 and an acquisition unit, and the signal transmission module includes a signal transmission mainboard 9 and a signal transmission unit. The acquisition mainboard 8 and the signal transmission mainboard 9 are arranged in parallel in the accommodating chamber 211 .
[0068] It is worth noting that the sensor 100 utilizes the bracket 4 to fix the acquisition module and the signal transmission module, and in particular, to fix the acquisition mainboard 8 and the signal transmission mainboard 9, thereby enabling them to be relatively fixedly installed in the accommodating chamber 211 of the housing 2, thereby avoiding electromagnetic interference from the electronic components located on the acquisition mainboard 8 and the signal transmission mainboard 9, and ensuring the stable operation of the acquisition module. It is also worth noting that the bracket 4 is tightly fitted with the accommodating chamber 211 of the housing 2 to achieve fixation, and the tight fit is achieved by the elastic portion 42 on the back of the bracket body 41. In this embodiment, there is only one elastic portion 42, which is located on one side of the bracket body 41, which facilitates installation and can ensure structural stability after installation. Accordingly, depending on the specific implementation environment, the elastic portion 42 can also be set on both sides of the bracket body 41. The source of the elastic force is the shape of the elastic portion 42, which is generated after being squeezed.
[0069] In this embodiment, if Figure 14 As shown, the elastic portion 42 includes a plurality of elastic pieces 421 arranged in parallel, and the plurality of elastic pieces 421 are independent of each other and do not contact each other. It is understood that, compared to an elastic structure having a single plate-like structure, the provision of a plurality of independent and non-contacting elastic pieces 421 can ensure the elastic effect while making it easier for the bracket 4 to be installed in the accommodating chamber 211.
[0070] Please refer again Figure 3 The sensor 100 further includes a plug-in 6, with the acquisition module and the signal transmission module respectively connected to either side of the plug-in 6, and the plug-in 6 is disposed in a position-limiting chamber 48. It is understood that the configuration of the plug-in can fix the acquisition main board 8 and the signal transmission main board 9 to each other, thereby preventing them from shifting and moving, which could affect the performance of the sensor.
[0071] In this embodiment, the bracket body 41 further includes a limiting groove 43 , and the acquisition main board 8 and the signal transmission main board 9 are respectively clamped in the limiting groove 43 .
[0072] It is worth noting that the acquisition module and signal transmission module are respectively connected to the two ends of the plug-in 6, and through the locking groove, a modular structure can be formed. This structural design makes the installation and removal of the sensor 100 more convenient, without the need for complex tools or procedures, and can be directly plugged in and out, reducing installation time and maintenance costs. In addition, the limit groove 43 can fix the acquisition main board 8 and the signal transmission main board 9 together, providing a stable mechanical connection, preventing the modules from loosening or shifting due to vibration or other external forces, ensuring the long-term stable operation of the acquisition module and the signal transmission module, and improving the reliability of the sensor 100.
[0073] Please refer again Figure 7 The top of the bracket body 41 is a snap-fit structure 46, shaped to match the battery module 10 and used to secure the battery module 10. The middle of the bracket body 41 features a retaining groove 43 and a fixing structure 44 for securing the acquisition module and the signal transmission module. The bottom of the bracket body 41 is a support structure 45 for securing the thermistor 7, which has a groove that matches the thermistor 7 and is used to secure the thermistor 7.
[0074] Please refer to Figure 5 The accommodating chamber 211 is a cylindrical cavity, and the acquisition module and the signal transmission module are both arranged in parallel in the accommodating chamber 211 along the axial direction of the accommodating chamber 211.
[0075] It is worth noting that in order to further reduce the overall volume of the sensor 100 and improve the utilization rate of the internal space, the acquisition module and the signal transmission module are respectively integrated into the acquisition main board 8 and the signal transmission main board 9, and arranged in parallel along the axial direction in the accommodating chamber 211 of the cylindrical cavity, which can effectively shorten the axial dimension of the sensor 100.
[0076] Please refer again Figure 3 and Figure 5 A flexible buffer material is added between the transmission antenna 12 and the battery module 10. Specifically, this embodiment uses a buffer pad 13, which can cooperate with the fixing glue 5 to fix the internal battery wire 11. This prevents the battery wire 11 from shaking and rubbing against other electronic components inside the sensor 100 due to vibration during actual use, causing damage to the internal wiring harness or other components, and shortening the service life of the sensor 100. Depending on the specific implementation environment, other flexible buffer materials can also be used to protect the battery wire 11.
[0077] Please refer again Figure 3 The acquisition unit includes a thermistor 7 and a temperature measuring circuit, the thermistor 7 is electrically connected to the temperature measuring circuit, and the environmental information includes temperature information.
[0078] In this embodiment, the signal transmitting unit includes a Bluetooth transmitting unit and a transmission antenna 12 , and the Bluetooth transmitting unit is electrically connected to the transmission antenna 12 .
[0079] Optionally, the transmission antenna 12 includes a flexible printed circuit antenna, a ceramic antenna, a printed circuit board antenna, a rod antenna or a copper tube antenna.
[0080] Specifically, a flexible printed circuit antenna can be used to improve the transmission distance and reliability of the Bluetooth transmitter. Furthermore, using a printed circuit board antenna or a ceramic antenna makes the sensor 100 more compact and suitable for scenarios with short reception distances and minimal external interference. Using a rod antenna or a copper tube antenna allows the sensor 100 to be used in scenarios with longer reception distances and greater external interference.
[0081] Please refer to Figure 6 and Figure 9 The bracket body 41 also includes a limiting hole 47, which is adapted to the limiting pin 24 of the shell 2, so that the bracket 4 can be fixed to the shell 2.
[0082] Please refer again Figure 2 The housing 2 includes a heat conducting portion 23, a fixing portion 22 and a body portion 21 connected in sequence. The accommodating chamber 211 is located in the body portion 21. The thermistor 7 is arranged in the hollow chamber of the heat conducting portion 23. The fixing portion 22 is configured to be connected to the temperature measuring portion. It can be understood that, if Figure 4 As shown, the temperature measuring part in this embodiment can be a structure such as an oil filling hole, an oil drain hole, etc. of the reduction gear box that is connected to the internal cavity of the reduction gear box.
[0083] Please refer to Figure 10 The hollow chamber is filled with thermally conductive adhesive 3 , and the thermally conductive adhesive 3 wraps the thermistor 7 .
[0084] It is worth noting that thermistor 7 extends into the hollow chamber of the heat-conducting portion 23 and is thermally connected to the inner wall of the heat-conducting portion 23 via the thermally conductive adhesive 3. This facilitates the rapid and uniform transfer of external temperature to the thermistor 7, thereby reducing heat loss and enabling the thermistor 7 to sense external temperature changes more quickly and accurately, thereby improving the response speed and accuracy of temperature measurement. At the same time, the thermally conductive adhesive 3 wraps around the thermistor 7, creating a good thermal coupling between the thermistor 7 and the surrounding environment. This not only increases the sensitivity of the thermistor 7 to the ambient temperature, but also reduces thermal interference caused by air or other impurities in the chamber, thereby reducing temperature measurement errors and ensuring more accurate measurement results.
[0085] Please refer to Figure 11 and Figure 12In another implementation of this embodiment, the outer contour of the heat conducting portion 23 is conical, the hollow chamber is a conical cavity, and the small diameter end surface of the heat conducting portion 23 is away from the fixing portion 22.
[0086] It is worth noting that the conical structure effectively increases the contact area between thermistor 7 and the heat conduction portion 23, allowing more heat to be transferred to thermistor 7 through the heat conduction path, thereby improving heat conduction efficiency, enabling thermistor 7 to more quickly sense external temperature changes and increasing measurement response speed. Furthermore, because the conical structure gradually tapers from the wide-diameter end to the small-diameter end, it creates a heat-collecting effect. The wide-diameter end collects external heat and gradually directs it toward the thermistor 7 at the small-diameter end, thereby accelerating heat transfer.
[0087] In this embodiment, the outer peripheral surface of the fixing portion 22 has an external thread.
[0088] It is worth noting that the threaded arrangement on the outer peripheral surface of the fixing portion 22 can fix the sensor 100 in the oil filling hole or oil drain hole of the reducer housing in a threaded fixing manner, which does not require major structural changes to the original mechanical components and is highly convenient.
[0089] Please refer again Figure 3 , further comprising a battery module 10, which is electrically connected to the acquisition module and the signal transmission module respectively to be configured to provide power.
[0090] In this embodiment, the battery module 10 is disposed in the accommodating chamber 211 and is located at an end away from the heat conducting portion 23 .
[0091] It is worth noting that the battery module 10 is arranged on top of the temperature acquisition module and the wireless transmission module. The battery module 10 is away from the heat source, which can reduce the impact of temperature changes on the battery. At the same time, it is compatible with the battery replacement solution, thereby improving the service life and ease of use of the sensor 100.
[0092] Please refer again Figure 3 The sensor 100 further includes a sealing unit, which is arranged on the fixing portion 22 .
[0093] In this embodiment, the sealing unit includes a sealing gasket 1, which is sleeved on the fixing portion 22. The sealing gasket 1 can be used to seal the cavity between the sensor 100 and the reduction gearbox. Optionally, depending on the specific implementation environment, the cavity between the sensor 100 and the reduction gearbox can also be sealed by applying sealant (thread glue) to the surface of the fixing thread.
[0094] In this embodiment, the sensor 100 further includes a rear cover 14 , which is connected to the body 21 to seal the accommodating chamber 211 .
[0095] Specifically, according to different application scenarios, the back cover 14 can have two structural forms:
[0096] 1. The back cover 14 is detachable. In this form, the sensor 100 can replace the battery module 10. When the battery is exhausted, the battery can be replaced to extend the service life of the sensor 100. It is used in scenarios with low vibration and airtightness requirements. Figure 15 As shown, in this embodiment, the battery module is detachably connected to the main body 21 via the spring 15 .
[0097] 2. The back cover 14 is not removable. In this case, the sensor 100 cannot be used to replace the battery module 10. The internal structure of the sensor 100 can be designed to be more compact, which can reduce the volume and weight of the sensor 100. It is used in scenes with severe vibration and strict airtightness requirements, such as automobiles. Figure 16 As shown, in this embodiment, the battery module is bonded to the main body 21 by a fixing adhesive 5 .
[0098] Please refer to Figure 13 The temperature measurement principle of the sensor 100 is shown in the figure: the thermistor 7, the temperature measurement circuit, the Bluetooth transmitting unit (here is the Bluetooth chip), and the transmission antenna 12 (here is the FPC antenna, i.e., the flexible printed circuit antenna) are connected in sequence, and the battery supplies power to the temperature measurement circuit and the Bluetooth chip respectively; the resistance of the thermistor 7 changes with temperature, and the measurement voltage in the temperature measurement circuit also changes accordingly. The Bluetooth chip converts the voltage value in the temperature measurement circuit into a temperature value through calculation, and finally sends the temperature data out through the antenna.
[0099] This embodiment also discloses a reduction gearbox, including the above-mentioned sensor 100, having all its beneficial effects.
