Description

Technical Field

[0001] This invention relates to the field of encoder mounting technology, and more specifically, to an encoder mounting structure. Background Technology

[0002] As a core feedback element in motor control systems, the reliability of the motor encoder's installation structure directly affects the accuracy, stability, and lifespan of the motor. In practical applications within the power industry, power companies have a wide distribution of substations, power supply stations, and dispatch centers. The operating environment of on-site equipment is complex, often involving vibration, dust, and alternating high and low temperatures, and the installation space for various equipment is often limited. When installing and maintaining critical equipment such as motors, encoders, and transmission mechanisms in power fields, common problems include poor adaptability of the installation structure, easy damage to the equipment's paint due to fixing methods, and loosening and displacement under vibration.

[0003] Furthermore, in the existing encoder installation structures of power companies, screws and mounting lugs are mostly used to fix the encoder to the rear of the motor. However, in the large or old-style motors manufactured in the past, there are no pre-drilled mounting holes for the encoder, which makes it difficult to install the encoder on these motors. In the existing technology, some patents propose fixing the encoder mounting structure to the protective mesh of the old-style motor to achieve the effect of fixing the encoder. However, some motors do not have protective meshes, and the types and models of protective meshes are also different, resulting in poor installation stability. In addition, because old-style motors and large motors have a large amount of vibration during operation, simple installation and fixing methods can easily cause the encoder to loosen between the encoder and the motor. Also, if it is a large motor, it is generally running for a long time. Under long-term operation, the motor will generate a lot of heat. Under the condition of a lot of heat, the encoder mounting structure may also be affected. Therefore, an encoder mounting structure is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an encoder mounting structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an encoder mounting structure, including a motor, an encoder is sleeved on the outside of the end shaft of the motor, a plurality of adjusting components are fixedly connected to the outside of the encoder, a telescopic component is movably connected to the outside of the adjusting components, and an adsorption structure is rotatably connected to the telescopic end of the telescopic component. The adsorption structure includes a rotating cover, which is rotatably connected to the telescopic end of the telescopic component. An internally threaded cylinder is fixedly connected to the center of the rotating cover. A threaded post is connected to the internal thread of the internally threaded cylinder. An adhesive suction cup is fixedly connected to the end of the threaded post away from the internally threaded cylinder. A top connection structure is movably connected between the rotating cover and the adhesive suction cup. The top connection structure includes a semi-rigid rubber air-storing shell. The semi-rigid rubber air-storing shell is used to push the adhesive suction cup to adhere to the outer wall of the motor by expansion. An air-suction structure is integrally formed on the outer wall of the semi-rigid rubber air-storing shell, which is used to automatically suction air from inside the semi-rigid rubber air-storing shell when the motor vibrates and causes the semi-rigid rubber air-storing shell to expand and rebound.

[0006] Preferably, the top connection structure further includes a lower semi-rigid bonding shell, which is fixedly connected to one side of the semi-rigid rubber gas storage shell. The side of the semi-rigid rubber gas storage shell away from the lower semi-rigid bonding shell is fixedly connected to the inner wall of the rotating cover. A one-way air inlet valve is installed on the outside of the semi-rigid rubber gas storage shell. A sliding sleeve is integrally formed at the center of the lower semi-rigid bonding shell. The sliding sleeve is slidably connected to the outside of the internal threaded cylinder. The lower semi-rigid bonding shell is used to push the lower semi-rigid bonding shell to the outer wall of the adhesive suction cup when the semi-rigid rubber gas storage shell expands due to continuous gas entering or when the gas inside the semi-rigid rubber gas storage shell expands due to heat generated by the motor. This pushes the adhesive suction cup to tightly adhere to the outer wall of the motor.

[0007] Preferably, the air intake structure includes an elastic section integrally formed in the middle of the semi-rigid rubber air storage shell. An arc-shaped guide bend is integrally formed inside the elastic section. The arc-shaped bend faces the inside of the semi-rigid rubber air storage shell. The elastic section and the arc-shaped guide bend are used to achieve their own contraction and rebound by means of vibration force when the motor generates vibration, thereby driving the semi-rigid rubber air storage shell to contract and rebound synchronously. During the reciprocating contraction and rebound process, the semi-rigid rubber air storage shell, in conjunction with the one-way air intake valve, realizes the one-way intake of gas.

[0008] Preferably, a copper heat-conducting plate is integrally formed on the bottom of the semi-rigid rubber gas storage shell and the bottom of the lower semi-rigid adhesive shell. A sealing membrane is integrally formed inside the semi-rigid rubber gas storage shell. A storage cavity is formed between the copper heat-conducting plate, the sealing membrane, and the semi-rigid rubber gas storage shell. The storage cavity is filled with cooling oil. Multiple heat-conducting pipes are integrally formed on the copper heat-conducting plate. The ends of the heat-conducting pipes away from the copper heat-conducting plate penetrate the outer walls of the sealing membrane and the rotating cover, respectively. The cooling oil and the copper heat-conducting plate are used to conduct heat dissipation for the heat transferred from the motor to the adhesive suction cup when the lower semi-rigid adhesive shell abuts against the outside of the adhesive suction cup.

[0009] Preferably, a first through hole is provided on the outside of the heat pipe, and a first one-way valve plate is fixedly connected to the outlet side of the first through hole. The first through hole is used to open the first one-way valve plate when the gas pressure inside the semi-rigid rubber gas storage shell reaches a specified level, thereby allowing the gas to be discharged to the outside through the heat pipe.

[0010] Preferably, a second through hole is provided on the outside of the heat pipe, and a second one-way valve is installed at the outlet end of the second through hole. The second through hole is used to allow the oil to push open the second one-way valve and enter the storage cavity through the second through hole when oil is injected into the storage cavity through the heat pipe, and to prevent the oil from leaking into the heat pipe through the second through hole.

[0011] Preferably, the adjustment component includes a square fixing box, multiple square fixing boxes are fixedly connected to the outside of the encoder, a threaded rod is rotatably connected inside the square fixing box, a movable seat is threadedly connected to the outside of the threaded rod, and a telescopic component is fixedly connected to the outside of the movable seat.

[0012] Preferably, the telescopic assembly includes an outer sleeve and an inner moving rod. The outer sleeve is fixedly connected to the outside of the movable seat, the inner moving rod is slidably connected to the inside of the outer sleeve, and the rotating cover is rotatably connected to the end of the inner moving rod away from the outer sleeve. A threaded hole is provided on the outside of the outer sleeve, and a bolt is threaded into the inside of the threaded hole.

[0013] Preferably, the outer wall surface of the inner moving rod and the inner wall surface of the outer sleeve are set as rough surfaces. The rough surfaces enhance the sliding resistance of the inner moving rod inside the outer sleeve and prevent the inner moving rod from sliding randomly inside the outer sleeve.

[0014] Preferably, a stirring plate is fixedly connected to the outside of the heat pipe. The stirring plate has multiple through holes on its outside and a hollow cavity inside. The hollow cavity inside the stirring plate is connected to the heat pipe. Gas enters the stirring plate through the heat pipe. The stirring plate is used to assist the cooling oil in dissipating heat when the gas inside the semi-rigid rubber gas storage shell enters the hollow cavity of the stirring plate through the heat pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the encoder is directly attached to the tail of the motor using a suction cup with adhesive, eliminating the need for drilling, mounting ears, and protective netting. This allows for the non-destructive and rapid installation of encoders on both older and larger motors. The adjustable and telescopic components provide radial and axial dual-dimensional adjustment to accommodate motors of different specifications and shapes. Furthermore, the top-mounted structure utilizes gas expansion to continuously tighten the suction cup, while the vibration-driven elastic section and arc-shaped guide bend enable automatic air replenishment, resolving issues such as airbag leakage, insufficient thrust, and vibration-induced loosening. Overall, the encoder offers convenient installation, vibration resistance, anti-loosening properties, and automatic voltage stabilization, enhancing its operational stability and lifespan under harsh conditions.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, such as Figure 1As shown, this application discloses an encoder mounting structure, including a motor 100, an encoder 101 is sleeved on the outside of the end shaft of the motor 100, a plurality of adjustment components 102 are fixedly connected to the outside of the encoder 101, a telescopic component 103 is movably connected to the outside of the adjustment components 102, and an adsorption structure is rotatably connected to the telescopic end of the telescopic component 103. The adsorption structure includes a rotating cover 104, which is rotatably connected to the telescopic end of the telescopic component 103. An internally threaded cylinder 107 is fixedly connected to the center of the rotating cover 104. A threaded post 106 is threadedly connected to the inside of the internally threaded cylinder 107. An adhesive suction cup 105 is fixedly connected to the end of the threaded post 106 away from the internally threaded cylinder 107. A top connection structure is movably connected between the rotating cover 104 and the adhesive suction cup 105. The top connection structure includes a semi-rigid rubber air-storing shell 200. The semi-rigid rubber air-storing shell 200 is used to push the adhesive suction cup 105 to adhere to the outer wall of the motor 100 by expansion. An air-suction structure is integrally formed on the outer wall of the semi-rigid rubber air-storing shell 200, which is used to automatically suction air from the inside of the semi-rigid rubber air-storing shell 200 when the motor 100 vibrates and causes the semi-rigid rubber air-storing shell 200 to extend and rebound as a whole.

[0020] Specifically, during use, the operator connects the connector of encoder 101 to the rear output shaft of motor 100. After connection, the position of telescopic component 103 is adjusted by adjusting component 102 on the outside of encoder 101, and then the telescopic length of telescopic component 103 is adjusted so that the rotating cover 104 at the telescopic end is aligned with the rear outer wall of motor 100. Then, the rotating cover 104 is rotated, which drives the internal threaded cylinder 107 to rotate synchronously. The internal threaded cylinder 107 drives the threaded post 106 to extend outward through thread engagement, thereby pushing the adhesive suction cup 105 to adhere to and bond to the outer wall of motor 100 to complete the initial fixation. After using multiple adhesive suction cups 105 to adhere to the rear outer wall of motor 100, the encoder 101 can be limited and fixed, which can adapt to motors 100 of different sizes to the greatest extent. Moreover, the encoder 101 can be installed on the output shaft of motor 100 without drilling holes, solving the problem of non-destructive installation of encoder 101 on old motors 100.

[0021] like Figures 2-5 As shown, the adjustment assembly 102 includes a square fixing box 500. Multiple square fixing boxes 500 are fixedly connected to the outside of the encoder 101. A threaded rod 501 is rotatably connected inside the square fixing box 500. A movable seat 502 is threadedly connected to the outside of the threaded rod 501. The telescopic assembly 103 is fixedly connected to the outside of the movable seat 502.

[0022] Specifically, during use, the operator can rotate the threaded rod 501 inside the square fixing box 500 to make the movable seat 502, which is threadedly connected to the threaded rod 501, move linearly along the internal space of the square fixing box 500. This will cause the telescopic component 103, which is fixed outside the movable seat 502, to move synchronously. This will allow the position of the telescopic component 103 and the adhesive suction cup 105 to be adjusted, so that the adhesive suction cup 105 can be accurately aligned with the target installation position on the outer wall of the motor 100, thus meeting the adaptation and installation requirements of motors 100 of different sizes.

[0023] like Figures 2-5 As shown, the telescopic assembly 103 includes an outer sleeve 600 and an inner moving rod 601. The outer sleeve 600 is fixedly connected to the outside of the moving base 502, and the inner moving rod 601 is slidably connected to the inside of the outer sleeve 600. The rotating cover 104 is rotatably connected to the end of the inner moving rod 601 away from the outer sleeve 600. A threaded hole is provided on the outside of the outer sleeve 600, and a bolt 602 is threadedly connected to the inside of the threaded hole.

[0024] Specifically, during installation, the operator can pull the inner moving rod 601 to slide it inside the outer sleeve 600, thereby adjusting the overall extension length of the telescopic component 103. This ensures that the rotating cover 104 at the end and the adhesive suction cup 105 are at the appropriate distance from the outer wall of the motor 100. After adjustment, tighten the bolt 602 in the threaded hole on the outer sleeve 600, so that the bolt 602 presses against the inner moving rod 601 to lock the position, thus completing the axial positioning of the adsorption structure. This ensures that the adhesive suction cup 105 can stably adhere to the outer wall of the motor 100, thereby adapting to motors 100 with protrusions at the rear and further expanding the installation of encoders 101 for different types of motors 100.

[0025] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, the radial position of the adhesive suction cup 105 can be adjusted by adjusting component 102, and the axial length can be adjusted by combining telescopic component 103. This can adapt to motors 100 of different sizes and shapes. During installation, the adhesive suction cup 105 is directly glued and fixed to the rear outer wall of the motor 100. After the glue is glued, the adhesive suction cup 105 can be continuously pushed to fit completely to the rear position of the motor 100 by twisting the rotating cover 104 in conjunction with the threaded column 106. In the process of installing the encoder 101 on an old-fashioned motor 100, no drilling is required, thus expanding the scope of application.

[0026] Example 2: Considering that the motor 100 will continuously vibrate during operation, and that continuous vibration and heat may cause a gap to form between the adhesive suction cup 105 and the motor 100 housing, potentially leading to detachment between the adhesive suction cup 105 and the motor 100, this application proposes a top-connection structure to address the aforementioned technical problem. Specifically: like Figures 1-3 As shown, the top connection structure also includes a lower semi-rigid adhesive shell 202, which is fixedly connected to one side of the semi-rigid rubber gas storage shell 200. The side of the semi-rigid rubber gas storage shell 200 away from the lower semi-rigid adhesive shell 202 is fixedly connected to the inner wall of the rotating cover 104. A one-way air inlet valve 201 is installed on the outside of the semi-rigid rubber gas storage shell 200. A sliding sleeve 203 is integrally formed at the center of the lower semi-rigid adhesive shell 202. The sliding sleeve 203 is slidably connected to the outside of the internal threaded cylinder 107. The lower semi-rigid adhesive shell 202 is used to push the lower semi-rigid adhesive shell 202 to adhere to the outer wall of the adhesive suction cup 105 when the semi-rigid rubber gas storage shell 200 expands due to continuous gas entering or when the motor 100 generates heat that causes the gas inside the semi-rigid rubber gas storage shell 200 to expand, thus pushing the adhesive suction cup 105 to adhere tightly to the outer wall of the motor 100.

[0027] Specifically, during use, when the semi-rigid rubber gas-storing housing 200 contains gas or when the motor 100 heats up and causes the internal gas to expand, it will expand and extend towards the adhesive suction cup 105. This will cause the lower semi-rigid bonding housing 202, which is fixed at its end, to move synchronously towards the adhesive suction cup 105. During the movement of the lower semi-rigid bonding housing 202, the sliding sleeve 203 integrally formed in the center of the lower semi-rigid bonding housing 202 slides stably along the outer wall of the internal threaded cylinder 107 to ensure guidance and coaxiality and avoid deviation. The expanded semi-rigid rubber gas-storing housing 200 pushes the lower semi-rigid bonding housing 202 to press tightly against the outer wall of the adhesive suction cup 105, thereby continuously pressing the adhesive suction cup 105 against and firmly attaching it to the outer wall of the motor 100, preventing gaps in the fit due to vibration or heat, and ensuring the stable installation of the encoder 101.

[0028] Furthermore, when it is necessary to replenish the gas inside the lower rigid bonding shell 202, gas can be continuously injected into the lower rigid bonding shell 202 by connecting an air pump through the one-way air inlet valve 201.

[0029] Furthermore, the connection between the sliding sleeve 203 and the lower semi-rigid adhesive shell 202 is soft, so when the semi-rigid rubber air-storing shell 200 expands, it can push the lower semi-rigid adhesive shell 202 to press against the outside of the adhesive suction cup 105 with the soft connection as the center.

[0030] Furthermore, considering that the motor 100 will continuously generate heat, the adhesive surface of the adhesive suction cup 105 can be partially made of heat-sensitive adhesive, which has stronger adhesion at higher temperatures.

[0031] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, by setting a top-connection structure composed of a semi-rigid rubber gas storage shell 200, a lower semi-rigid bonding shell 202, a one-way air inlet valve 201 and a sliding sleeve 203, when the motor 100 heats up and causes the gas to expand, the expansion pushes the lower semi-rigid bonding shell 202 to stably press against the adhesive suction cup 105, solving the problem that the adhesive suction cup 105 is prone to gaps and easy detachment due to continuous vibration and heat of the motor 100, and improving the installation stability and bonding reliability of the encoder 101 during long-term operation.

[0032] Example 3: Considering that the gas inside the semi-rigid rubber gas storage shell 200 will slowly leak, and that in the event of slow leakage, the gas pressure is insufficient and the motor 100 operates for a short period of time, resulting in insufficient heat to generate enough expansion force for the semi-rigid rubber gas storage shell 200 with low gas pressure, this application proposes the following technical solution to address the above-mentioned technical problems: like Figures 2-4 As shown, the air intake structure includes an elastic section 300 integrally formed in the middle of the semi-rigid rubber air storage shell 200. An arc-shaped guide bend 301 is integrally formed inside the elastic section 300. The arc-shaped bend of the arc-shaped guide bend 301 faces inward towards the interior of the semi-rigid rubber air storage shell 200. The elastic section 300 and the arc-shaped guide bend 301 are used to achieve their own contraction and rebound by means of vibration force when the motor 100 vibrates, thereby driving the semi-rigid rubber air storage shell 200 to synchronously contract and rebound. During the reciprocating contraction and rebound process, the semi-rigid rubber air storage shell 200, in conjunction with the one-way air intake valve 201, achieves one-way air intake.

[0033] Specifically, during use, the vibration generated by the motor 100 is transmitted to the semi-rigid rubber air-storing housing 200. This vibration causes the semi-rigid rubber air-storing housing 200 to vibrate, resulting in continuous contraction and rebound movements of the integrally formed elastic segment 300 and the internal arc-shaped guide segment 301 under the force of the vibration. The concave arc-shaped structure of the arc-shaped guide segment 301 guides the elastic segment 300 to reciprocate stably. This causes the semi-rigid rubber gas storage shell 200 to expand and contract synchronously. Each time the semi-rigid rubber gas storage shell 200 expands and rebounds, it creates an internal negative pressure. When the internal negative pressure is formed, the one-way air intake valve 201 automatically draws in gas through the negative pressure. When it contracts, it prevents the gas from flowing back. Thus, without the need for an external air pump, the motor 100 can automatically replenish a small amount of air to the semi-rigid rubber gas storage shell 200 through its own vibration. The overall air pressure requirement inside the semi-rigid rubber gas storage shell 200 can be met without the need for an air pump.

[0034] Considering that if the motor 100 runs continuously, excessively high temperatures can cause the adhesive suction cup 105 to soften, leading to unstable adhesion or affecting the stability of the adhesive. Furthermore, even when using heat-sensitive adhesive, prolonged high temperatures can have a primary impact on the suction cup surface of the adhesive suction cup 105. To address these technical problems, this application proposes the following technical solution: like Figures 3-4 As shown, a copper heat-conducting plate 400 is integrally formed on the bottom of the semi-rigid rubber gas storage shell 200 and the bottom of the lower semi-rigid adhesive shell 202. A sealing film 401 is integrally formed inside the semi-rigid rubber gas storage shell 200. A storage cavity is formed between the copper heat-conducting plate 400, the sealing film 401 and the semi-rigid rubber gas storage shell 200. The storage cavity is filled with cooling oil. Multiple heat-conducting pipes 402 are integrally formed on the copper heat-conducting plate 400. The ends of the heat-conducting pipes 402 away from the copper heat-conducting plate 400 pass through the sealing film 401 and the outer wall of the rotating cover 104 respectively. The cooling oil and the copper heat-conducting plate 400 are used to conduct heat dissipation on the heat transferred from the motor 100 to the adhesive suction cup 105 when the lower semi-rigid adhesive shell 202 abuts against the outside of the adhesive suction cup 105.

[0035] Specifically, during use, the heat transferred from the motor 100 to the adhesive suction cup 105 is quickly absorbed by the copper heat-conducting plate 400 integrally formed on the bottom of the semi-rigid rubber air-storing shell 200 and the lower semi-rigid adhesive shell 202. The copper heat-conducting plate 400 conducts the heat to the cooling oil in the storage cavity. The cooling oil stores and diffuses the heat. At the same time, the heat is conducted outward through multiple heat-conducting pipes 402 integrally formed on the copper heat-conducting plate 400. The heat-conducting pipes 402 penetrate the sealing membrane 401 and the outer wall of the rotating cover 104 and dissipate the heat to the external environment. With the synergistic effect of the copper heat-conducting plate 400, the cooling oil and the heat-conducting pipes 402 can continuously dissipate heat from the adhesive suction cup 105, preventing the adhesive suction cup 105 from softening and failing due to high temperature, and ensuring the stable installation of the encoder 101.

[0036] like Figures 4-6 As shown, a first through hole 700 is provided on the outside of the heat pipe 402. A first one-way valve plate 701 is fixedly connected to the outlet side of the first through hole 700. The first through hole 700 is used to open the first one-way valve plate 701 when the internal air pressure of the semi-rigid rubber gas storage shell 200 reaches a specified level, thereby allowing the gas to be discharged to the outside through the heat pipe 402.

[0037] Specifically, during use, the semi-rigid rubber gas storage shell 200 will expand due to continuous automatic air intake or heat from the motor 100, causing its internal gas pressure to rise continuously. When the internal gas pressure rises to a set safety threshold, the high-pressure gas will push open the first one-way valve 701 on the outlet side of the first through hole 700 on the outer wall of the heat pipe 402, and the excess gas will be discharged outward along the channel of the heat pipe 402, preventing the semi-rigid rubber gas storage shell 200 from over-expanding or even breaking due to excessive gas pressure.

[0038] Furthermore, when gas passes through the heat pipe 402, it can also help dissipate heat from the auxiliary heat pipe 402. The auxiliary heat pipe 402 quickly dissipates heat to the outside, thus achieving the effect of auxiliary heat dissipation.

[0039] like Figures 4-7 As shown, a second through hole 800 is provided on the outside of the heat pipe 402. A second one-way valve plate 801 is installed at the outlet end of the second through hole 800. The second through hole 800 is used to allow oil to be injected into the storage cavity through the heat pipe 402, so that the oil pushes open the second one-way valve plate 801 and enters the storage cavity through the second through hole 800. The second one-way valve plate 801 also prevents the oil from leaking into the interior of the heat pipe 402 through the second through hole 800.

[0040] Specifically, during use, when it is necessary to add cooling oil to the storage cavity formed by the copper heat-conducting plate 400, the sealing film 401, and the semi-rigid rubber gas storage shell 200, the cooling oil can be injected from the port of the heat-conducting pipe 402. Under pressure, the oil pushes open the second one-way valve plate 801 at the outlet end of the second through hole 800 on the outer wall of the heat-conducting pipe 402, and smoothly enters the storage cavity through the second through hole 800 to complete the oil injection. After the oil injection is completed, the second one-way valve plate 801 automatically closes, effectively preventing the cooling oil in the storage cavity from flowing back and leaking into the heat-conducting pipe 402 through the second through hole 800 during equipment operation, ensuring the stability of the cooling oil storage sealing and heat conduction and heat dissipation functions.

[0041] Furthermore, both the first one-way valve 701 and the second one-way valve 801 are similar to the pressure valve in the "scream" beverage mouthpiece, which will open when subjected to sufficient pressure and close when the pressure is lost.

[0042] Considering that the continuously operating motor 100 generally reaches a high temperature during installation, although there are some cooling structures, the continuously overflowing high temperature may exceed the cooling limit of the cooling oil. To address the aforementioned technical problems, this application proposes the following technical solution: like Figures 4-8 As shown, a stirring plate 900 is fixedly connected to the outside of the heat pipe 402. The stirring plate 900 has multiple through holes 901 on its outside. The inside of the stirring plate 900 is a hollow cavity. The hollow cavity inside the stirring plate 900 is connected to the heat pipe 402. Gas enters the stirring plate 900 through the heat pipe 402. The stirring plate 900 is used to assist the cooling oil in dissipating heat when the gas inside the semi-rigid rubber gas storage shell 200 enters the hollow cavity of the stirring plate 900 through the heat pipe 402.

[0043] Specifically, during use, the gas inside the semi-rigid rubber gas storage shell 200 enters the hollow cavity inside the stirring plate 900 connected to it via the heat conduction pipe 402. The stirring plate 900, along with the gas flow and equipment vibration, generates disturbance in the cooling oil within the storage cavity. This, combined with the multiple through holes 901 on the plate, further disperses the cooling oil, increasing the contact area between the cooling oil and the copper heat conduction plate 400 and the heat conduction pipe 402. At the same time, the gas entering the hollow cavity continuously carries away heat, thereby significantly improving the heat dissipation efficiency of the cooling oil and enhancing the heat dissipation effect on the contact area between the adhesive suction cup 105 and the motor 100, preventing high temperature from causing adhesion failure.

[0044] Furthermore, considering the complexity of the processing between the stirring plate 900 and the heat pipe 402, the stirring plate 900 is only customized when the motor 100 is installed at a specific high temperature. A connecting structure can also be set between multiple stirring plates 900. On the inverted motor 100, the expansion and contraction of the semi-rigid rubber gas storage shell 200 can be used to form a cooling oil circulation effect, which serves as a technical supplement to enhance the cooling effect (not shown in the figure above).

[0045] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, the air intake structure composed of the elastic segment 300, the arc-shaped guide bend 301, and the one-way air intake valve 201, when the air intake structure is formed, utilizes the vibration of the motor 100 itself to automatically replenish the air to the semi-rigid rubber air storage shell 200, solving the problems of slow air leakage of the airbag and insufficient expansion thrust under low heat conditions. Stable bonding pressure can be maintained without the need for an external air pump. At the same time, in conjunction with the heat dissipation structure composed of the copper heat conduction plate 400, cooling oil, and heat conduction pipe 402, the heat transferred from the motor 100 to the adhesive suction cup 105 can be discharged, avoiding the phenomenon of the suction cup softening and bonding failure caused by high temperature, and improving the installation stability and service life of the encoder 101 under long-term vibration and high temperature conditions.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
