Description

Technical Field

[0001] The utility model relates to the field of motor servo transmission, in particular to a temperature sensor installation structure and a motor. Background Art

[0002] Temperature is a crucial monitoring indicator during motor operation. Excessively high temperatures can damage internal motor components, impacting the motor's lifespan and safety. Therefore, temperature sensors are often integrated into the motor's stator assembly to monitor the motor's operating temperature in real time.

[0003] In the related art, the traditional method of installing temperature sensors usually directly places the temperature sensor probe near the stator winding of the motor. Although this method is simple, on the one hand, the temperature sensor probe and the winding cannot directly contact each other, which can easily cause temperature measurement deviation and affect the accuracy of temperature readings; on the other hand, during the operation of the motor, there may be vibration between the temperature sensor probe and the winding, affecting the stability of the contact and even causing contact failure, so additional fixing measures are required to fix the position of the temperature sensor and the probe. For example, some structures use specific clamping devices to fix the temperature sensor, but this will introduce additional fixing components, which on the one hand increases the manufacturing cost and assembly complexity, and on the other hand, the installation position of the temperature sensor is greatly restricted due to the need to match the introduced fixing components, which cannot well meet industrial needs.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] As mentioned above, the traditional temperature sensor installation method in the related art usually directly places the temperature sensor probe near the stator winding of the motor. Although this method is simple, on the one hand, the temperature sensor probe and the winding cannot directly contact each other, which can easily cause temperature measurement deviation and affect the accuracy of the temperature reading; on the other hand, during the operation of the motor, there may be vibration between the temperature sensor probe and the winding, affecting the stability of the contact and may even cause contact failure, so additional fixing measures are required to fix the position of the temperature sensor and the probe. For example, some structures use a specific clamping device to fix the temperature sensor, but this will introduce additional fixing components, which on the one hand increases the manufacturing cost and assembly complexity, and on the other hand, the installation position of the temperature sensor is greatly restricted due to the need to match the introduced fixing components, which cannot well meet industrial needs.

[0045] Reference below Figures 1 to 6 The temperature sensor installation structure and the motor according to the embodiment of the present invention are described.

[0046] Reference Figures 1 to 6 The temperature sensor of the present application includes a stator assembly, a temperature measuring assembly 300, a sleeve 400, and a reinforcement layer 500. Specifically, the stator assembly includes a main body 100 and at least one copper wire 200, the copper wire 200 being connected to the main body 100 and protruding from the main body 100. The temperature measuring assembly 300 has a temperature measuring end 310, which is in contact with the copper wire 200. The temperature measuring end 310 and at least one copper wire 200 are passed through the sleeve 400, and the sleeve 400 clamps the copper wire 200 and the temperature measuring end 310 to keep them in contact. The reinforcement layer 500 covers at least a portion of the outer wall of the sleeve 400 to fix the sleeve 400. The main body 100 of the stator assembly is a component of the motor, and one or more copper wires 200 are connected to the main body 100. These copper wires 200 are used to transmit current and serve as detection objects of the temperature sensor. The copper wire 200 protrudes from the main body 100, facilitating the installation of the temperature measuring assembly 300. The temperature measuring end 310 of the temperature measuring assembly 300 is tightly attached to the copper wire 200 to directly measure the temperature change of the copper wire 200, thereby making the monitoring effect of the temperature measuring assembly 300 more accurate.

[0047] Reference Figure 3 and Figure 4In some embodiments, the sleeve 400 is sleeved around the outside of the copper wire 200 and the temperature measuring end 310. The sleeve's tightening action ensures a tight fit between the copper wire 200 and the temperature measuring end 310, thereby ensuring the accuracy of temperature measurement. Furthermore, the use of the sleeve 400 to maintain the connection between the temperature measuring end 310 and the copper wire 200 can accommodate copper wires 200 of various positions and shapes. Therefore, the arrangement of the temperature measuring end 310 of the present application has a wider range of options, thereby making the temperature sensor installation structure of the present application more adaptable, less expensive, and more conducive to industrial production. Furthermore, the sleeve 400 is a flexible sleeve. For example, the sleeve 400 can be a heat shrink sleeve made of a material such as fluororubber or polytetrafluoroethylene as a base material. Considering the fact that the copper wire 200 of the stator assembly is prone to heating during actual operation, the hotter the copper wire 200 is, the tighter the heat shrink sleeve clamps the copper wire 200 and the temperature measuring end 310, thereby strengthening the connection between the copper wire 200 and the temperature measuring end 310. Of course, it is understandable that in order to facilitate the installation of the temperature sensor structure of the present application, it can be pre-installed through the sleeve 400. Specifically, when the sleeve 400 is a heat shrink sleeve, on the one hand, the heat shrink sleeve sleeved on the copper wire 200 can be tightened by preheating the copper wire 200, thereby pre-positioning the heat shrink sleeve and the copper wire 200 and the temperature measuring end 310; on the other hand, the heat shrink sleeve can be first hung on the protruding copper wire 200, and then the heat shrink sleeve can be heated and tightened by blowing hot air or other means, thereby achieving pre-positioning of the heat shrink sleeve and the copper wire 200 and the temperature measuring end 310.

[0048] Reference Figure 6 In some embodiments, the reinforcing layer 500 covers the outer wall of the sleeve 400 and plays the role of fixing the sleeve 400. The reinforcing layer 500 can be a coating powder. Specifically, the coating powder can be taken from the original powder material in the stator production process. The copper wire 200, the temperature measuring end 310 and the sleeve 400 are inserted into the coating powder together, so that the coating powder wraps the sleeve 400, and then the entire body coated with the coating powder is heated, and the coating powder condenses into a solid state to form a rigid shell. Such a design is equivalent to adding a rigid shell to the sleeve 400, thereby reducing the probability of deformation of the sleeve 400, making the sleeve 400 more stable and firm in fixing the copper wire 200 and the temperature measuring end 310.

[0049] Further elaborating on the beneficial effects of the coating powder melting into a solid state, the coating powder melts during heating and solidifies to form a hard shell. This shell not only provides additional mechanical protection but also prevents damage to the sleeve 400 from external environmental factors such as heat and vibration. By placing the sleeve 400 in the coating powder and solidifying the powder after heating, a stable structure is formed, allowing the sleeve 400 to remain stable even in complex environments, thereby improving the overall reliability of the temperature sensor.

[0050] It is understandable that the material selection for reinforcement layer 500 fully utilizes the remaining powder from the stator production process, which not only reduces costs but also achieves efficient resource utilization. The reinforcement layer 500, formed by the powder material through heating and curing, has excellent physical and chemical properties and can effectively resist external environmental influences such as vibration and corrosion, thereby improving the overall durability of the temperature sensor. Furthermore, because the material of reinforcement layer 500 is consistent with that of the stator assembly, the bond between the two is more compact, reducing the thermal expansion coefficient mismatch caused by material differences, thereby improving the stability and accuracy of the temperature sensor.

[0051] Of course, it is understandable that in some embodiments, the sleeve can be made of a material with a relatively high hardness, and a sleeve of a suitable caliber can be designed to be compactly sleeved around the copper wire 200 and the temperature measuring end 310. In addition, when the sleeve is made of a material with a relatively high hardness, a powder coating can be applied simultaneously to the copper wire 200, the temperature measuring end 310, and the sleeve to stabilize the position of the sleeve and the positions of the copper wire 200 and the temperature measuring end 310, thereby ensuring that, in actual operation, the temperature sensor mounting structure of the present application is difficult for the sleeve to fall off the copper wire 200 and / or the temperature measuring end 310 to separate from the copper wire 200.

[0052] Reference Figure 2 In some embodiments, at least two copper wires 200 are passed through the casing 400. Specifically, the temperature measuring end 310 can be attached to one of the copper wires 200 in the casing 400, or the temperature measuring end 310 can be attached to at least two of the copper wires 200 in the casing 400 at the same time. Directly attaching the temperature measuring end 310 to the copper wires 200 can improve the accuracy of temperature measurement.

[0053] Regarding the form in which the temperature measuring end 310 is attached to only one copper wire 200, in some embodiments, the two copper wires 200 are not attached together, and the temperature measuring end 310 is attached to a separate copper wire 200 to detect the temperature of the copper wire 200. In some embodiments, the two copper wires 200 are attached together, and the temperature measuring end 310 is attached to one of the copper wires 200. Since copper is a thermally conductive material, the temperature of the two copper wires 200 is uniform after being attached. Therefore, the temperature measured by the temperature measuring end 310 tends to an average value, avoiding the influence of extreme temperatures, and thus the temperature measurement is more accurate. Specifically, the temperature measuring end 310 is located on the side of one of the copper wires 200 facing away from the adjacent copper wire 200. The copper wire 200 to which the temperature measuring end 310 is attached is in close contact with another copper wire 200. The good thermal conductivity between the two copper wires 200 ensures that the temperature measuring end 310 can accurately capture the average temperature of the entire group of copper wires 200, thereby helping to reduce measurement errors caused by local temperature fluctuations and further improving the accuracy of temperature measurement. In other words, this design allows the temperature measuring end 310 to not only directly sense the temperature changes of the attached copper wire 200, but also indirectly sense the temperature changes of adjacent copper wires 200, thereby improving temperature measurement accuracy. In addition, this design can also simplify the installation process of the temperature sensor, reduce the need to adjust the position of the temperature measuring end 310 during installation, and reduce manufacturing costs.

[0054] Regarding the simultaneous contact of the temperature measuring end 310 with at least two copper wires 200 within the sleeve 400, it is understood that in some embodiments, the two copper wires 200 are adjacent, and the contact position of the temperature measuring end 310 is set on a side surface perpendicular to the mutually facing surface of the two adjacent copper wires 200, that is, the temperature measuring end 310 simultaneously contacts the side surfaces of the two copper wires 200. In some embodiments, the temperature measuring end 310 is sandwiched between the two copper wires 200 to achieve a configuration in which the temperature measuring end 310 simultaneously contacts the two copper wires 200. When the temperature measuring end 310 contacts multiple copper wires 200, it will be affected by the temperatures of the multiple copper wires 200. This design can better reflect the temperature status of the entire group of copper wires 200, thereby improving the accuracy of temperature measurement. In addition, the presence of multiple copper wires 200 can also increase the stability of the temperature measuring assembly 300, preventing temperature measurement failures due to the breakage of a single copper wire 200.

[0055] Reference Figure 2 、 Figure 4 and Figure 5In some embodiments, the stator assembly includes multiple straight segments, each comprising two copper wires 200. The multiple straight segments are arranged radially along the stator assembly to form a first group, and the reinforcement layer 500 covers at least two straight segments in the first group. This structural design ensures that the reinforcement layer 500 not only secures the sleeve 400 but also enhances the radial stability of the stator assembly. The reinforcement layer 500 covering at least two straight segments provides reinforcement at at least two locations in the radial direction, which increases the overall structural strength and stability of the temperature sensor mounting structure.

[0056] Next, let's explain how the reinforcing layer 500 covers the at least two straight segments of the first group. Because the sleeve 400 is positioned over the temperature-measuring end 310 and the copper wire 200, the reinforcing layer 500 covers the outer wall of the sleeve 400, and the reinforcing layer 500 covers at least two straight segments, the sleeve 400 is connected to the outer straight segments. This arrangement prevents the sleeve 400 from vibrating simply with the vibrations of the copper wire 200 passing through it; instead, it is restrained by the other outer straight segments. This results in a more stable state for the sleeve 400, effectively tightening the temperature-measuring end 310 and the copper wire 200 passing through it.

[0057] It will be appreciated that in some embodiments, when the reinforcement layer 500 is a coating powder obtained during the stator production process, since the reinforcement layer 500 utilizes the original powder material from the stator production process, it maintains good compatibility with other components of the stator assembly. The thickness of the reinforcement layer 500 can be adjusted according to actual needs to accommodate different operating environments. Furthermore, the reinforcement layer 500 can be enhanced by adding anti-corrosion agents or other special ingredients to further extend the service life of the temperature sensor.

[0058] Reference Figure 5 and Figure 6 In some embodiments, all radially extending straight segments are covered by the reinforcement layer 500. When the reinforcement layer 500 covers all straight segments in the first group, it not only improves the radial stability of the structure but also ensures greater radial consistency across the entire temperature measuring end 310 mounting structure, reducing the risk of failure due to local instability. The reinforcement layer 500 also further improves the durability of the temperature end, particularly during long-term operation or in harsh environments. This design significantly reduces maintenance requirements and costs.

[0059] Reference Figure 1 、 Figure 5 and Figure 6In some embodiments, the stator assembly includes a plurality of straight segments, each of which includes two copper wires 200. The plurality of straight segments are arranged circumferentially around the stator assembly to form a second group, and the reinforcement layer 500 covers at least two straight segments of the second group. This structural design allows the reinforcement layer 500 to not only fix the sleeve 400, but also enhance the circumferential stability of the stator assembly. The reinforcement layer 500 covers at least two straight segments, which means that at least two positions in the circumferential direction are reinforced, which makes the overall structural strength of the temperature sensor mounting structure higher, more stable and reliable. By covering the reinforcement layer 500 on a plurality of circumferentially arranged straight segments, not only can the sleeve 400 be effectively fixed, but this design can also make the temperature measuring end 310 have better consistency in the circumferential direction, increase the circumferential stability of the structure, and reduce the risk of failure caused by local instability.

[0060] Of course, it is understandable that the reinforcement layer 500 can also cover the straight line segments in the first group and the second group at the same time to ensure the stability of the structure of the present application.

[0061] Reference Figure 5 and Figure 6 In some embodiments, the reinforcement layer 500 covers the opening of the sleeve 400 to achieve a sealing effect. By covering the opening of the sleeve 400, the reinforcement layer 500 can effectively prevent the external environment from affecting the internal copper wire 200 and the temperature measuring end 310. For example, it prevents external impurities such as dust and moisture from entering the sleeve and affecting the operating performance of the temperature measuring component 300, thereby ensuring the normal operation and measurement accuracy of the temperature sensor.

[0062] Reference Figure 5 and Figure 6 In some embodiments, at least two copper wires 200 are inserted into the casing and soldered to each other, with the solder joints of the two copper wires 200 being covered by the reinforcement layer 500. This arrangement effectively prevents the solder joints of the two copper wires 200 from breaking due to the reinforcement layer 500's structural reinforcement.

[0063] It is understood that to ensure accurate temperature measurement of the solder joint of copper wire 200 during motor operation, the temperature measuring end 310 is placed as close to the solder joint as possible, where it contacts the copper wire 200. Positions far from the solder joint may be affected by other heat or cooling sources, leading to deviations in the measurement results. Positions close to the solder joint minimize these interference factors and improve measurement accuracy.

[0064] Reference Figure 1 and Figure 2In some embodiments, the copper wire 200 is flat, and its outer circumference includes a first surface and a second surface disposed opposite each other. The area of ​​the first surface is larger than that of the second surface, and at least one of the first surfaces is in contact with the temperature measuring end 310. The larger first surface allows the temperature measuring end 310 to abut against the first surface, thereby creating a larger contact surface between the temperature measuring end 310 and the copper wire 200. This ensures that the temperature measuring end 310 can more accurately detect temperature changes in the copper wire 200, thereby improving the overall measurement accuracy of the temperature sensor. Furthermore, it provides a more stable contact between the temperature measuring end 310 and the copper wire 200.

[0065] It is understandable that, in some embodiments, the design of the flat copper wire 200 not only increases the contact area between the temperature measuring end 310 and the copper wire 200, but also makes the fit between the temperature measuring end 310 and the copper wire 200 more stable. Since the first surface area of ​​the copper wire 200 is larger, the temperature measuring end 310 can better transfer heat after being fitted therewith, thereby improving the sensitivity and accuracy of temperature detection. In addition, the design of the flat copper wire 200 also helps to reduce the thermal resistance between the copper wire 200 and the temperature measuring end 310, thereby accelerating the heat transfer speed, improving the temperature response time, and enabling the temperature sensor to react to temperature changes more quickly. This design is particularly suitable for situations where a quick response to temperature changes is required, such as high-speed motors.

[0066] Reference Figures 1 to 6An embodiment of the second aspect of the present application provides a motor, which adopts the temperature sensor mounting structure of any of the aforementioned embodiments, and the temperature sensor mounting structure includes a stator assembly, a temperature measuring assembly 300, a sleeve 400 and a reinforcement layer 500. The stator assembly includes a main body 100 and at least one copper wire 200, and the copper wire 200 is connected to the main body 100 and protrudes from the main body 100. The temperature measuring assembly 300 has a temperature measuring end 310, and the temperature measuring end 310 is in contact with the copper wire 200. The temperature measuring end 310 and at least one copper wire 200 are passed through the sleeve 400, and the sleeve 400 clamps the copper wire 200 and the temperature measuring end 310 to keep the copper wire 200 and the temperature measuring end 310 in contact. The reinforcement layer 500 covers at least a portion of the outer wall of the sleeve 400 to fix the sleeve 400. In the temperature sensor installation structure of this embodiment, the temperature measuring end 310 of the temperature sensor is in direct contact with the copper wire 200, which has higher monitoring accuracy; and through the limiting method of the sleeve 400, the structure is simple, which facilitates the installation of the temperature measuring end 310 and enriches the installation position of the temperature sensor. The reinforcement layer 500 covers at least part of the outer wall of the sleeve 400 to consolidate the fixation of the shape of the sleeve 400 and further ensure the stable contact between the temperature measuring end 310 and the copper wire 200. Therefore, in the motor of this embodiment, the connection between the copper wire 200 and the temperature measuring end 310 is maintained by means of the sleeve 400, the distribution position of the temperature measuring end 310 is wider, and the reinforcement layer 500 consolidates the limiting effect of the sleeve 400, further strengthening the stability of the connection between the temperature measuring end 310 and the copper wire 200.
