Description

Technical Field

[0001] The present invention belongs to the technical field of new energy motors, and particularly relates to a sensor and process for quickly fixing and accurately measuring temperature on a motor copper bar. Background Art

[0002] In a new energy oil-cooled flat wire motor, temperature monitoring is crucial for the stable operation and performance optimization of the motor.

[0003] Traditional fixing methods such as tying may cause the tying rope to loosen due to the vibration during motor operation, resulting in a change in the relative position between the temperature sensor and the copper bar, affecting the temperature measurement accuracy; the tying method and position will affect the contact surface between the temperature sensor and the copper bar, and there will be air gaps, affecting the temperature measurement accuracy and thermal response time. In addition, some special fixing structures require complex processes and molds to complete the installation of the sensor, increasing the production time and material cost.

[0004] It is difficult to adapt to different motors. New energy oil-cooled flat wire motors of different models and specifications have differences in copper bar size, shape, and internal structure of the motor. Existing temperature sensor fixing and temperature measurement solutions may not be able to well adapt to various motor types, and need to be customized for different motors, increasing the cost and technical difficulty. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sensor and process for quickly fixing and accurately measuring temperature on a motor copper bar that can overcome or at least partially solve the above problems.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: A sensor for quickly fixing and accurately measuring temperature on a motor copper bar, including a motor copper bar, and further including: a temperature sensor is installed on the motor copper bar through a heat shrinkable sleeve; the heat shrinkable sleeve, on both inner walls of the two sides inside the heat shrinkable sleeve, a first thickening area is symmetrically provided, and on the top inner wall of the heat shrinkable sleeve, a second thickening area is provided; a first conveying pipe and a second conveying pipe for conveying the heat shrinkable sleeve; a first clamping plate and a second clamping plate for clamping and fixing the motor copper bar.

[0007] Preferably, it further includes: a base, a support member, the support member is arranged on the base, and the first conveying pipe and the second conveying pipe are arranged on the support member.

[0008] Further, a fixing rod is provided on the base, the first clamping plate and the second clamping plate are arranged on the fixing rod, wherein, a sliding groove is opened on the fixing rod, and the first clamping plate slides on the sliding groove.

[0009] Further, a sliding ring is provided at one end of the first clamping plate close to the sliding groove, and the sliding ring is sleeved on the fixing rod.

[0010] Furthermore, perforations are provided on both the first clamping plate and the second clamping plate. A threaded block is provided on the second clamping plate. A threaded rod is provided in the perforations on the first clamping plate and the second clamping plate. One end of the threaded rod is threadedly connected to the threaded block, and a knob is provided at the other end of the threaded rod. A baffle that fits against the first clamping plate is fixedly connected to the threaded rod.

[0011] Furthermore, a retaining rod is provided on the sliding ring.

[0012] Preferably, the temperature sensor is composed of a temperature measuring end and a wire harness. An installation part is provided on the motor busbar, and the temperature measuring end is installed on the installation part.

[0013] Furthermore, two second thickening areas are symmetrically provided. A number of extension parts are provided on the second thickening areas. Arc-shaped tensile parts are provided at one ends of the plurality of extension parts away from the second thickening areas. A low-pressure space is formed between the two arc-shaped tensile parts.

[0014] Furthermore, rotating parts are rotatably connected to both sides of the temperature measuring end. The rotating parts are composed of a rotating fulcrum, a compressive part, a rotating part, and an inclined surface part. Anti-slip teeth are provided on the inclined surface part. In the initial state, the compressive part is higher than the temperature measuring end. When the compressive part is pressed and rotates downward, the rotating part forms an accommodation space.

[0015] Preferably, a process for the rapid fixing and precise temperature measurement of a sensor applied on a motor busbar includes the following steps:

[0016] S1. Cut the heat shrinkable tube.

[0017] S2. Thread the tube.

[0018] S3. Heat shrink the tube.

[0019] S4. Check the heat shrinkage.

[0020] Compared with the prior art, the present invention provides a sensor and a process for the rapid fixing and precise temperature measurement on a motor busbar, and has the following beneficial effects:

[0021] 1. The sensor and the process for the rapid fixing and precise temperature measurement on the motor busbar can quickly and firmly fix the temperature sensor on the motor busbar through the heat shrinkable tube, simplify the installation process, improve the production efficiency. Compared with the traditional binding or buckling methods, the fixing method through the heat shrinkable tube does not require additional tools and a long installation time.

[0022] 2. The sensor and process for rapid fixation and precise temperature measurement on the motor copper bar. During the shrinkage process of the heat shrinkable sleeve, two thickened areas symmetrically arranged on the inner walls on both sides shrink inward and adhere to both sides of the temperature sensor, and the second thickened area fits on the temperature sensor. This isolates the inside of the temperature sensor from the outside world, avoids air flow, reduces the air gap between the temperature sensor, the heat shrinkable sleeve and the motor copper bar, and improves the temperature measurement accuracy and thermal response time.

[0023] 3. The sensor and process for rapid fixation and precise temperature measurement on the motor copper bar. A layer of high-temperature resistant liquid glue can be coated on the upper surface of the temperature measurement end. When the heat shrinkable sleeve shrinks, the liquid glue gathers in the low-pressure space and forms a buffer layer with the low-pressure space, thereby protecting the probe at the temperature measurement end and preventing the probe at the temperature measurement end from being damaged.

[0024] For the parts not involved in the sensor and process for rapid fixation and precise temperature measurement on the motor copper bar, they are the same as the prior art or can be implemented using the prior art. The present invention can install the temperature sensor on different types of motor copper bars, and at the same time, reduce the air gap between the temperature sensor and the motor copper bar, improving the temperature measurement accuracy and thermal response time.

Specific embodiments

[0037] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0038] It should be understood that terms such as "having", "including", and "comprising" as used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0039] In the description of the present invention, the orientation or positional relationship indicated by terms such as "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0040] Example 1: Refer to Figures 1 - 10, A sensor and process for quickly fixing and accurately measuring temperature on a motor copper bar, including the motor copper bar 7, further including: a temperature sensor 8 is installed on the motor copper bar 7 through a heat shrinkable sleeve 9; the heat shrinkable sleeve 9, on both inner walls of the inside of the heat shrinkable sleeve 9, a first thickening area 901 is symmetrically provided on each side, and a second thickening area 13 is provided on the top inner wall of the inside of the heat shrinkable sleeve 9; a first conveying pipe 201 and a second conveying pipe 202 for conveying the heat shrinkable sleeve 9; a first clamping plate 4 and a second clamping plate 5 for clamping and fixing the motor copper bar 7.

[0041] In the present invention, the temperature sensor 8 is installed on the motor copper bar 7 through the heat shrinkable sleeve 9. The heat shrinkable sleeve 9 can quickly and firmly fix the temperature sensor 8 on the motor copper bar 7, simplifies the installation process, and improves production efficiency. Compared with the traditional binding or buckling method, the fixing method through the heat shrinkable sleeve 9 does not require additional tools and a long installation time;

[0042] The two first thickening areas 901 symmetrically arranged on both inner walls of the inside of the heat shrinkable sleeve 9, when the heat shrinkable sleeve 9 is heated and shrunk, the two first thickening areas 901 symmetrically arranged on both inner walls contract inward and adhere to both sides of the temperature sensor 8, and the second thickening area 13 fits on the temperature sensor 8. In this way, the inside of the temperature sensor 8 is isolated from the outside, avoiding air flow, reducing the air gap between the temperature sensor 8, the heat shrinkable sleeve 9 and the motor copper bar 7, and improving the temperature measurement accuracy and thermal response time;

[0043] The first clamping plate 4 and the second clamping plate 5 are used to clamp and fix the motor copper bar 7;

[0044] The first conveying pipe 201 and the second conveying pipe 202 are used to convey and cut the heat shrinkable sleeve 9. Among them, a cutting device can be arranged at the gap between the first conveying pipe 201 and the second conveying pipe 202 for cutting the heat shrinkable sleeve 9. The heat shrinkable sleeve 9 can be moved manually by pushing, or a conveying device (such as a conveyor belt, a push rod) can be arranged to control the heat shrinkable sleeve 9 to be sleeved on the temperature sensor 8 and the motor copper bar 7.

[0045] Example 2: Refer to Figures 1 - 10, which is basically the same as Embodiment 1. Further, it further includes: a base 1 and a support member 2. The support member 2 is arranged on the base 1, and a first conveying pipe 201 and a second conveying pipe 202 are arranged on the support member 2; a fixing rod 3 is provided on the base 1, and a first clamping plate 4 and a second clamping plate 5 are arranged on the fixing rod 3. Among them, a chute 301 is formed on the fixing rod 3, and the first clamping plate 4 slides on the chute 301; a sliding ring 401 is provided at one end of the first clamping plate 4 close to the chute 301, and the sliding ring 401 is sleeved on the fixing rod 3; perforations are formed on both the first clamping plate 4 and the second clamping plate 5, a threaded block 501 is provided on the second clamping plate 5, a threaded rod 6 is arranged in the perforations on the first clamping plate 4 and the second clamping plate 5, one end of the threaded rod 6 is threadedly connected to the threaded block 501, a knob 602 is arranged at the other end of the threaded rod 6, and a baffle 601 that fits the first clamping plate 4 is fixedly connected to the threaded rod 6; a stop rod 402 is arranged on the sliding ring 401.

[0046] In the present invention, the first clamping plate 4 slides on the chute 301. During use, first place the motor copper bar 7 between the first clamping plate 4 and the second clamping plate 5, and then rotate the knob 602 to thread the threaded rod 6 into the threaded block 501. During this process, the baffle 601 pushes the first clamping plate 4, so that the first clamping plate 4 and the second clamping plate 5 clamp and fix the motor copper bar 7, thereby facilitating the precise sleeving of the heat shrinkable tube 9;

[0047] The sliding ring 401 makes the sliding process of the first clamping plate 4 more stable. At the same time, the upper end of the stop rod 402 will fit against the side of the motor copper bar 7. In this way, when the heat shrinkable tube 9 is inserted, the heat shrinkable tube 9 will be blocked by the stop rod 402, so that the heat shrinkable tube 9 is fixed at a position corresponding to the temperature sensor 8, making the fixing and heat shrinking effects of the heat shrinkable tube 9 better;

[0048] Further, the stop rod 402 can be arranged to be slidably connected to the sliding ring 401, so that motor copper bars 7 of different models can be used.

[0049] Embodiment 3: Refer to Figures 1 - 10 , which is basically the same as Embodiment 2. Further, the temperature sensor 8 is composed of a temperature measuring end 801 and a wire harness 802. An installation part 701 is provided on the motor copper bar 7, and the temperature measuring end 801 is installed on the installation part 701; two thickening areas II 13 are symmetrically provided, a plurality of extension parts 1301 are provided on the thickening areas II 13, and an arc-shaped tensile part 1302 is provided at one end of the plurality of extension parts 1301 away from the thickening areas II 13. A low-pressure space 14 is formed between the two arc-shaped tensile parts 1302; rotating parts 10 are rotatably connected to both sides of the temperature measuring end 801. The rotating parts 10 are composed of a rotating fulcrum 1001, a compression-resistant part 1002, a rotating part 1003, and an inclined surface part 1004. Anti-slip teeth 11 are provided on the inclined surface part 1004. In the initial state, the compression-resistant part 1002 is higher than the temperature measuring end 801. When the compression-resistant part 1002 is pressed and rotates downward, the rotating part 1003 forms a receiving space 12.

[0050] In the present invention, after placing the temperature measuring end 801 of the temperature sensor 8 on the mounting portion 701, the heat shrinkable sleeve 9 cut into single pieces is sleeved on the temperature measuring end 801, and then a heating device such as a hot air gun is used to cause the heat shrinkable sleeve 9 to shrink, fixing the temperature sensor 8 on the mounting portion 701. The good conformability of the heat shrinkable sleeve 9 enables the temperature measuring end 801 of the temperature sensor 8 to be in close contact with the motor copper busbar 7, reducing the temperature measurement error caused by poor contact, thereby realizing the accurate measurement of the temperature of the motor copper busbar 7. At the same time, the heat shrinkable sleeve 9 has good insulation performance, which can effectively prevent the leakage accident between the temperature sensor 8 and the motor copper busbar 7, improving the safety of the motor. In addition, the heat shrinkable sleeve 9 can also play a certain protective role for the temperature sensor 8, avoiding its erosion and damage by the external environment;

[0051] When placing the temperature sensor 8, an inorganic filler (such as silicon nitride) can be coated on the lower surface of the temperature measuring end 801 or the upper surface of the mounting portion 701 to improve its high temperature resistance, increase its thermal expansion coefficient, improve the heat conduction effect of the motor copper busbar 7, and make the detection of the temperature sensor 8 more sensitive;

[0052] During the shrinking process of the heat shrinkable sleeve 9, two thickened areas 901 symmetrically arranged on the inner walls on both sides shrink inward and adhere to both sides of the temperature sensor 8, and the thickened area 13 adheres to the temperature sensor 8, so that the inside of the temperature sensor 8 is isolated from the outside, avoiding air flow, reducing the air gap between the temperature sensor 8, the heat shrinkable sleeve 9 and the motor copper busbar 7, and improving the temperature measurement accuracy and thermal response time;

[0053] Furthermore, when the thickened area 13 shrinks, the arc-shaped tensile part 1302 is pulled by the extension part 1301, and two arc-shaped tensile parts 1302 at both ends of the heat shrinkable sleeve 9 form a low-pressure space 14 at the central part of the heat shrinkable sleeve 9, where the pressure received is the smallest. The probe of the temperature measuring end 801 is directly below the low-pressure space 14, thus avoiding the shrinkage stress generated during the heat shrinkage of the heat shrinkable sleeve 9 from squeezing the probe of the temperature measuring end 801;

[0054] A layer of high-temperature resistant liquid glue (polytetrafluoroethylene type) can be coated on the upper surface of the temperature measuring end 801. When the heat shrinkable sleeve 9 shrinks, the liquid glue gathers in the low-pressure space 14 to form a buffer layer with the low-pressure space 14, thereby protecting the probe of the temperature measuring end 801 and avoiding damage to the probe of the temperature measuring end 801;

[0055] Further, when the heat-shrinkable sleeve 9 shrinks, since the compression part 1002 is higher than the temperature measurement end 801, the compression part 1002 is first squeezed by the heat-shrinkable sleeve 9. The compression part 1002 moves downward, and the rotating part 1003 moves upward until the inclined surface part 1004 is flush with the temperature measurement end 801. At this time, a receiving space 12 is formed below the rotating part 1003, and the first thickening area 901 can shrink into the receiving space 12, making the isolation between the inside of the temperature sensor 8 and the outside more complete;

[0056] A convex part 15 is provided at the middle part on the side of the temperature measurement end 801. The heat-shrinkable sleeve 9 will shrink on the convex part 15 and wrap the convex part 15. The first thickening area 901 shrinks into the receiving space 12 to form a friction point. At the same time, the anti-slip teeth 11 also form a friction point with the heat-shrinkable sleeve 9. In this way, a fixed point similar to a triangle is formed between the heat-shrinkable sleeve 9 and the temperature measurement end 801, making the fixation of the heat-shrinkable sleeve 9 to the temperature measurement end 801 more stable.

[0057] Example 4: Refer to Figures 1 - 10 , which is basically the same as Example 3. Furthermore: A process for the rapid fixation and precise temperature measurement of a sensor applied on a motor copper bar includes the following steps:

[0058] S1. Cut the heat-shrinkable sleeve 9,

[0059] S2. Thread the sleeve,

[0060] S3. Heat-shrink the sleeve,

[0061] S4. Check the heat-shrinkage.

[0062] In the present invention, the first conveying pipe 201 and the second conveying pipe 202 are used to convey and cut the heat-shrinkable sleeve 9. Among them, a cutting device can be arranged at the gap between the first conveying pipe 201 and the second conveying pipe 202 for cutting the heat-shrinkable sleeve 9. After the heat-shrinkable sleeve 9 is cut, the single-piece heat-shrinkable sleeve 9 cut is controlled to be sleeved on the temperature measurement end 801 and the installation part 701 of the temperature sensor 8, and then the heat-shrinkable sleeve 9 is heat-shrunk by a hot air gun, so that the temperature sensor 8 is fixed on the motor copper bar 7. After the heat-shrinkage is completed, check the heat-shrinkage effect;

[0063] It should be noted that in the present invention, the installation method of the temperature sensor 8 on the installation part 701 is not limited. Please refer to Figure 1 , when placing the temperature sensor 8, lifting and clamping components can be set to fix the temperature sensor 8; at the same time, the motor copper bar 7 can also be placed flat, and the temperature sensor 8 is directly placed on the installation part 701; the specific placement method is configured according to actual production requirements and is not limited here, only a few examples are given.

[0064] The above embodiments only illustrate several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the substantial technology of the present invention, and all of these fall within the protection scope of the present invention.
