Description

Technical Field

[0001] This invention relates to the field of new energy charging equipment technology, and in particular to a modular quick-change new energy vehicle charging pile with a guide rail structure. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the scale of supporting charging infrastructure construction continues to expand. Modular charging piles, with their flexible layout and strong adaptability, are widely used in various scenarios such as public parking areas, commercial districts, and communities. As the core power supply component, the power module of the charging pile directly affects the overall usage status of the charging pile due to its operational stability and ease of replacement.

[0003] Currently, most modular new energy vehicle charging piles on the market use a fixed plug-in installation structure for their power modules, maintaining a constant connection between the power module and the charging pile's electrical connection structure. During fast charging, the connection point continuously experiences temperature rises, leading to heat accumulation and potentially causing abnormal temperature increases, electrical connection abnormalities, and impacting the charging pile's operational safety. Most existing charging piles lack a targeted temperature-linked isolation structure, failing to promptly disconnect the connection when abnormally high temperatures occur in the connection area, making it difficult to avoid electrical safety hazards caused by high temperatures.

[0004] Meanwhile, existing modular charging piles lack suitable guiding and positioning structures and auxiliary removal structures for power module disassembly and assembly, resulting in limited alignment accuracy of power module insertion and making it difficult to achieve rapid and accurate docking during installation. During power module replacement and maintenance, the lack of dedicated auxiliary structures for module removal and hoisting alignment makes it difficult to guarantee the alignment stability and operational efficiency of the disassembly and assembly operations.

[0005] In addition, the sealing and protective structures on the outside of the charging piles are mostly fixed structures or simple opening and closing structures. The opening and closing states lack hierarchical limit and access control structures. The opening and closing states of the protective structures cannot accurately match the abnormal separation and routine replacement of the power modules, making it difficult to adapt to the equipment protection and maintenance needs in different scenarios. There is room for improvement in the protective sealing and working condition adaptability of the internal structure of the charging pile. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing charging piles, such as the inability to disconnect in time when the power connection position experiences abnormal temperature rise, insufficient precision in the disassembly and assembly of the power module, and poor adaptability for maintenance. This invention proposes a modular quick-change charging pile for new energy vehicles with a guide rail structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A modular quick-change new energy vehicle charging pile with a guide rail structure includes a rain shelter. Multiple charging pile bodies are fixedly installed under the rain shelter. An extension plate is fixedly installed on the bottom side of one side of each charging pile body. Two symmetrically arranged fixed slide rails are fixedly installed on the inner walls of both sides of the extension plate. A sliding block is slidably connected to the fixed slide rail. A connecting plate is fixedly installed on one side of the sliding block. An mounting plate is fixedly installed on one end of the connecting plate. A common sealing baffle is fixedly installed on one end of each of the four mounting plates. The sealing baffle is used to seal one end of the extension plate. Limiting components for limiting the connection plate are provided on both sides of the charging pile body. A rectangular cavity is formed on one inner wall of the main body of the charging pile, and the rectangular cavity is connected to the extension plate; It also includes a mounting housing and a power module. The top of the mounting housing has a mounting cavity for accommodating the power module. A rectangular groove is formed on one side of the mounting housing. A power receiving plate is fixedly installed on the inner wall of one side of the rectangular cavity. Two symmetrically arranged plug holes are formed on one side of the power receiving plate. Two symmetrically arranged connectors are fixedly installed on one side of the power module. The connectors engage with the plug holes. A positioning component for positioning the power module is provided inside the mounting housing. The bottom inner wall of the rectangular cavity is provided with a moving component for pushing the mounting housing to move.

[0008] In one possible design, the limiting component includes a side slide plate slidably connected to the outer wall of the charging pile body via a slider and a slide rail. One side of the side slide plate has multiple stripes integrally formed. Both sides of the charging pile body have strip-shaped vertical holes. A movable vertical plate is fixedly installed on one side of the side slide plate, sliding through the strip-shaped vertical holes. A protrusion is fixedly installed at one end of the movable vertical plate. Two symmetrically arranged side panels are fixedly installed on one side of the connecting plate. Threaded holes I are provided inside the side panels. A mounting vertical plate is detachably connected between the two side panels via bolts. Multiple threaded holes II that mate with threaded holes I are provided inside the mounting vertical plate. A notch is provided on one side of the mounting vertical plate. The mounting vertical plate and the movable vertical plate are offset, and the protrusion mates with the notch.

[0009] In one possible design, the positioning component includes two symmetrically arranged positioning vertical holes on one side of the mounting cavity, which are used in conjunction with the connector. Side vertical holes are provided on both sides of the mounting cavity. A lifting groove communicating with the side vertical holes is provided on the bottom inner wall of the mounting cavity. An inclined groove III is provided on one side of the rectangular groove. An inclined groove II is provided on the top of the mounting cavity. An inclined groove I is provided on the top of the positioning vertical holes.

[0010] In one possible design, two symmetrically arranged clearance grooves are provided on one side of the bottom of the mounting housing, a sliding vertical plate is slidably connected to the bottom inner wall of the rectangular cavity, a push plate is fixedly installed on the top of the sliding vertical plate, the push plate is used in conjunction with the clearance grooves, and a same return spring is provided between one side of the push plate and one side of the inner wall of the rectangular cavity.

[0011] In one possible design, a heat-conducting sheet is fixedly embedded inside the junction box, and the two ends of the heat-conducting sheet are connected to two plug holes. A temperature sensor and a controller are installed inside the charging pile body. The controller is electrically connected to the temperature sensor, and the temperature sensor is connected to the heat-conducting sheet.

[0012] In one possible design, the moving component includes a lead screw rotatably connected to the inner wall of one side of a rectangular cavity. Two symmetrically arranged T-shaped rails are fixedly installed on the bottom inner wall of the rectangular cavity. The top of the two T-shaped rails are slidably connected to the same support L-shaped plate. The bottom of the support L-shaped plate has two symmetrically arranged T-shaped holes, which are slidably connected to the T-shaped rails. A push side plate is fixedly installed at one end of the support L-shaped plate, and the push side plate abuts against one side of the mounting housing.

[0013] In one possible design, two symmetrically arranged limiting side plates I are fixedly installed on one side of the sealing baffle, and a supporting base plate is fixedly installed on the bottom of one side of the limiting side plate I. Two symmetrically arranged limiting side plates II are fixedly installed on the bottom inner wall of the rectangular cavity. A planar sliding groove is opened on one side of the top of the limiting side plate II, and a connected inclined sliding groove is opened on one side of the planar sliding groove. A strip groove is opened on one side of the bottom of the limiting side plate II. The strip groove is used in conjunction with the supporting base plate. Two symmetrically arranged moving wheels are rotatably connected to both sides of the mounting shell. The moving wheels are used in conjunction with the supporting base plate, the inclined sliding groove, and the planar sliding groove.

[0014] In one possible design, a servo motor is fixedly installed on the bottom inner wall of the rectangular cavity, and synchronous pulleys are fixedly installed on the outer walls of the output shaft and lead screw of the servo motor, with the same synchronous belt sleeved on the outer walls of the two synchronous pulleys.

[0015] In this application, if the internal electrical connection temperature is too high during use and there is a potential danger, the heat-conducting sheet can sense the temperature and then start the servo motor through the temperature sensor and the controller. The output shaft of the servo motor drives the lead screw to rotate through the synchronous pulley and synchronous belt. At this time, the lead screw drives the support L-shaped plate to move laterally, and the support L-shaped plate drives the push side plate to move laterally. At this point, the push side plate no longer contacts one side of the mounting housing. Since the return spring is always in a compressed state, the spring force of the return spring can drive the push plate and the sliding vertical plate to move laterally. The push plate pushes the mounting housing open. The mounting housing can drive the internal power module to move laterally by sliding the moving wheel on the top of the flat slide groove. The power module drives the connector to move out of the plug hole, releasing the plug state and avoiding accidents. At this point, the push side plate is at the extreme position of the two flat slide grooves, preventing the mounting housing from moving into the interior of the inclined slide groove. If the power module needs to be replaced, the servo motor can be started again. At this time, the side plate will continue to move, and the elastic force of the return spring will continue to push the mounting shell to the inside of the inclined slide, and it will start to slide down. As the side plate moves forward, it will eventually land on the support base plate. When it is necessary to open the sealing baffle, it also needs to be unlocked. The specific operation is as follows: move the side sliding plates on both sides upward. The side sliding plates drive the moving vertical plate to slide inside the strip vertical hole. At this time, the moving vertical plate drives the protrusion to move upward, so that the protrusion is aligned with the notch. Then the protrusion no longer blocks the installation vertical plate, and the sealing baffle can be pushed open normally by pushing the side plate. The sealing baffle drives the connecting plate and the sliding block to slide on the fixed slide rail, ensuring the stability of the device movement. The installation vertical plate is detachably connected between the two side panels by bolts. The position of the installation vertical plate can be adjusted as needed, thereby changing the height of the notch on both sides. In addition, the stripes on the outside of the side sliding plates only let the staff know that the height is adjusted, preventing unauthorized personnel from opening it. When removing the power module, a hoisting device can be inserted into the lifting slot to move the lifting plate below the power module, from which the power module can be removed. When placing the power module, the device can be aligned using the inclined slot II. The inclined slot I can work with the connector to achieve alignment, ensuring that the power module is quickly hoisted into the mounting cavity. The rectangular groove corresponds to the power board, and the inclined slot III ensures that the rectangular groove and the power board are fully engaged, thus ensuring the insertion depth of the connector.

[0016] Beneficial Effects: This application features a temperature-sensing linkage separation structure. Through a heat-conducting sheet embedded within the connector board, along with a temperature sensor and controller, the temperature status of the connector area can be monitored in real time. When an abnormally high temperature occurs in the connector area, a servo motor is automatically triggered. Relying on a synchronous pulley and belt, the lead screw rotates, driving the support L-shaped plate and pushing the side plate to shift. Combined with the elastic force of a return spring, this pushes the mounting housing laterally, allowing the connector to quickly disengage from the connector hole and promptly disconnect the electrical connection. This effectively avoids electrical safety risks in high-temperature environments and improves the safety and stability of the charging pile operation.

[0017] This application features a tiered module removal guide structure. By setting planar and inclined slides on the limiting side plate II, and cooperating with the casters at the bottom of the mounting housing, the power module can be displaced in stages. Under abnormal high-temperature conditions, the pushing side plate is limited to the extreme position of the planar slide, achieving only plug-in separation and ensuring temporary safety of the equipment. Under routine maintenance and replacement conditions, the mounting housing can slide to the inclined slide and fall onto the support base plate, completing the smooth removal of the module and adapting to the usage requirements of different working scenarios.

[0018] This application features a multi-dimensional alignment auxiliary structure, forming multiple alignment guide structures through inclined grooves I and II inside the mounting cavity, and inclined groove III at the rectangular recess. During the power module hoisting and installation process, precise alignment of the entire module, connectors, and junction boxes can be achieved, ensuring the insertion depth and mating accuracy of the connectors, and improving the fit and electrical connection reliability of the power module assembly. Simultaneously, the lifting groove provides dedicated operating space for hoisting equipment, facilitating the hoisting and placement of the power module.

[0019] This application features an adjustable limit unlocking structure. Utilizing side sliding plates, movable vertical plates, and protrusions on both sides of the charging pile body, along with a detachable mounting vertical plate at the connecting plate, the mounting position of the vertical plate can be adjusted via bolts, changing the corresponding height of the notch and thus allowing for adjustable settings of the sealing baffle unlocking conditions. The striped structure on the outer side of the side sliding plates provides visual feedback on the adjusted height, enabling effective control over opening and closing permissions and enhancing the safety and controllability of the equipment.

[0020] This application adopts a sliding rail type sealing protection structure. The sealing baffle slides and cooperates with the fixed sliding rail on the inner side of the extension plate through the connecting plate, sliding block and the sliding plate, so that the opening and closing process of the sealing baffle has good sliding stability, which can stably realize the sealing protection of the end of the extension plate, ensure the sealing environment of the rectangular cavity inside the charging pile body, reduce the impact of the external environment on the internal electrical structure and moving structure, and ensure the long-term stable operation of the equipment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] In one embodiment: Refer to Figures 1-9This embodiment discloses a modular quick-change new energy vehicle charging pile with a guide rail structure. A rainproof canopy 1 is fixedly mounted on the top of the equipment, and multiple charging pile bodies 2 are fixedly arranged below the rainproof canopy 1. Relying on the shielding performance of the rainproof canopy 1, a stable external protective environment can be provided for the charging pile bodies 2 below. An extension plate 4 is fixedly mounted on the bottom of one side of the charging pile body 2. Two sets of symmetrically arranged fixed slide rails 8 are fixedly installed on the inner walls of both sides of the extension plate 4. Sliding blocks 28 are slidably mounted on the surface of each set of fixed slide rails 8. A connecting plate 27 is fixedly connected to the side of each sliding block 28 that is close to each other. An mounting plate 26 is fixedly mounted on the end of the connecting plate 27 away from the sliding block 28. The ends of the four mounting plates 26 are jointly fixedly connected to the same sealing baffle 5. The sealing baffle 5 can completely seal the end of the extension plate 4, thereby maintaining the closed state of the internal cavity of the charging pile body 2. Limiting components are correspondingly mounted on both sides of the charging pile body 2. The limiting components can constrain the sliding state of the connecting plate 27, ensuring the positional stability of the sealing baffle 5 under normal use.

[0025] A rectangular cavity 9 is formed inside one side of the charging pile body 2. The rectangular cavity 9 is interconnected with the internal space of the bottom extension plate 4, providing space for the assembly and movement of the internal electrical and moving structures. The equipment is also equipped with a mounting shell 36 and a power module 51. A mounting cavity 47 is formed on the top of the mounting shell 36. The internal cavity of the mounting cavity 47 is used to accommodate the power module 51. A rectangular groove 49 is formed on one side wall of the mounting shell 36. A junction plate 7 is fixedly mounted on one side inner wall of the rectangular cavity 9. Two sets of symmetrically arranged plug holes 12 are formed on the surface of the junction plate 7. Two sets of symmetrically arranged plug connectors 43 are fixedly mounted on the side of the power module 51 facing the junction plate 7. The plug connectors 43 can be plugged into the plug holes 12 to realize the electrical connection between the power module 51 and the charging pile body. The internal assembly of the mounting housing 36 is a positioning component that can achieve precise alignment and positioning during the assembly of the power module 51. The bottom inner wall of the rectangular cavity 9 is equipped with a moving component that can drive the overall lateral displacement of the mounting housing 36, thereby completing the docking and separation of the power module 51.

[0026] Furthermore, the limiting component includes a side sliding plate 3, which is slidably mounted on the outer wall surface of the charging pile body 2 through a sliding block and slide rail cooperation structure. The outer wall of the side sliding plate 3 is integrally formed with multiple anti-slip stripes, which can improve the visibility and friction of the plate surface. Both sides of the charging pile body 2 have vertically formed strip-shaped holes 10. A movable vertical plate 21 is fixedly mounted on the side of the side sliding plate 3 facing the inside of the pile body. The movable vertical plate 21 slides through the strip-shaped holes 10, and a protrusion 24 is fixedly mounted on the inner end of the movable vertical plate 21. Two sets of symmetrically arranged side panels 29 are fixedly mounted on the outer wall of the connecting plate 27. Each side panel 29 has a threaded hole I6 inside. The two side panels 29 are detachably mounted with a vertical plate 22 by bolts. The plate body of the mounting vertical plate 22 has multiple threaded holes II25 that correspond to and match the threaded holes I6. The mounting vertical plate 22 has a notch 23 on the side facing the protrusion 24. The mounting vertical plate 22 and the movable vertical plate 21 are arranged in a staggered structure. The protrusion 24 can form a locking and limiting fit with the notch 23. Under normal use, the protrusion 24 abuts against the plate surface of the mounting vertical plate 22, which limits the sliding stroke of the connecting plate 27 and the sealing baffle 5, preventing the sealing baffle 5 from being pushed open arbitrarily. When it is necessary to unlock the sealing baffle 5, the side sliding plate 3 slides vertically, causing the moving vertical plate 21 to slide vertically along the inside of the strip-shaped vertical hole 10. This causes the protrusion 24 to move upward and align with the notch 23. The protrusion 24 then releases its obstruction of the mounting vertical plate 22. At this time, the sealing baffle 5 can slide along the fixed slide rail 8 with the connecting plate 27 and the sliding block 28, thus enabling the opening operation of the end of the extension plate 4. The operator can adjust the assembly position of the mounting vertical plate 22 between the two side panels 29 by removing and installing the connecting bolts, thereby changing the vertical height of the notch 23. The stripes on the surface of the side sliding plate 3 provide intuitive feedback on the height adjustment, allowing for flexible control of the unlocking conditions of the sealing baffle 5.

[0027] Furthermore, the positioning assembly includes two sets of symmetrically formed positioning vertical holes 44 on one side of the mounting cavity 47. The hole structure of the positioning vertical holes 44 is matched and adapted to the connector 43, providing initial guidance for the insertion action of the connector 43. Vertical side holes 40 are formed on both side walls of the mounting cavity 47. A lifting groove 48 is formed on the bottom inner wall of the mounting cavity 47, which communicates internally with the side vertical holes 40, allowing external hoisting equipment to extend into the cavity. An inclined groove III 50 is formed on the inner wall of the rectangular groove 49, an inclined groove II 46 is formed on the top inner wall of the mounting cavity 47, and an inclined groove I 45 is formed at the top opening of the positioning vertical holes 44. During the hoisting and assembly of the power module 51, the inclined groove II 46 can center and limit the overall position of the power module 51, the inclined groove I 45 can match the insertion trajectory of the connector 43 to achieve precise alignment, and the inclined groove III 50 can ensure that the rectangular groove 49 and the power board 7 are fully fitted and engaged, effectively ensuring the insertion depth of the connector 43 and improving the stability of the electrical connection.

[0028] Specifically, two sets of symmetrically arranged clearance grooves 42 are provided on the bottom side of the mounting housing 36. A sliding vertical plate 17 is slidably mounted on the bottom inner wall of the rectangular cavity 9, and a push plate 20 is fixedly mounted on the top of the sliding vertical plate 17. The plate structure of the push plate 20 matches and engages with the clearance grooves 42. A return spring 19 is fixedly mounted between the push plate 20 and the inner wall of the rectangular cavity 9. The return spring 19 is always kept in a compressed state and can continuously provide lateral thrust to the push plate 20. When the equipment triggers the high-temperature avoidance mechanism, the moving component releases its limiting contact with the mounting housing 36, the return spring 19 releases its elastic potential energy, and pushes the sliding vertical plate 17 and the push plate 20 to slide laterally. The push plate 20 drives the overall displacement of the mounting housing 36 through the cooperation structure with the clearance grooves 42, quickly completing the separation operation of the connector 43 and the connector hole 12.

[0029] Preferably, a heat-conducting sheet 11 is fixedly embedded inside the junction box 7. Both ends of the heat-conducting sheet 11 are in contact with the walls of the two insertion holes 12, allowing for real-time acquisition of the operating temperature at the insertion location. A temperature sensor and controller are installed inside the charging pile body 2. The detection end of the temperature sensor is connected to the heat-conducting sheet 11, and the controller is electrically connected to the temperature sensor. The temperature sensor can transmit the temperature signal collected by the heat-conducting sheet 11 to the controller in real time. The controller determines the operating status of the device based on a preset temperature threshold and automatically triggers subsequent separation actions when the temperature is abnormal. Preferably, the heat-conducting sheet 11 is made of copper, which has excellent thermal conductivity response speed and can ensure the real-time and accuracy of temperature detection. The return spring 19 is made of alloy spring steel, which has stable elastic deformation performance and can maintain the compressed energy storage state for a long time. The controller can receive the temperature signal collected by the temperature sensor and control the servo motor 18 to start and stop according to the preset threshold. The heat-conducting sheet 11 can sense the temperature change at the power connection position in real time and transmit it to the temperature sensor. The temperature sensor transmits the simulated temperature signal to the controller. The controller has a preset temperature threshold. When the detected temperature exceeds the threshold, the controller automatically outputs a control signal to start the servo motor 18.

[0030] Based on this, the moving component includes a lead screw 14, which is rotatably mounted on one side of the inner wall of the rectangular cavity 9. Two sets of symmetrically arranged T-shaped rails 13 are fixedly mounted on the bottom inner wall of the rectangular cavity 9. The tops of the two T-shaped rails 13 jointly support a support L-shaped plate 33. Two sets of symmetrically arranged T-shaped holes 41 are provided at the bottom of the support L-shaped plate 33. The T-shaped holes 41 slide and match the T-shaped rails 13, limiting the movement trajectory of the support L-shaped plate 33 and ensuring the stability of lateral sliding. A push side plate 37 is fixedly mounted on the vertical end plate of the support L-shaped plate 33. The surface of the push side plate 37 abuts against the side wall of the mounting housing 36. The displacement of the support L-shaped plate 33 can drive the push side plate 37 to move synchronously, thereby achieving limiting and pushing control of the mounting housing 36. A servo motor 18 is fixedly mounted on the bottom inner wall of the rectangular cavity 9. The output shaft of the servo motor 18 and the outer wall of the lead screw 14 are both fixedly mounted with synchronous pulleys 15. The outer sides of the two synchronous pulleys 15 are fitted with a synchronous belt 16 for transmission connection. When the servo motor 18 is working, it can drive the lead screw 14 to rotate stably through the transmission cooperation between the synchronous pulleys 15 and the synchronous belt 16, thereby driving the support L-shaped plate 33 to slide laterally along the T-shaped track 13.

[0031] The sliding and transmission mating structures such as the fixed slide rail 8, T-shaped rail 13, and lead screw 14 are equipped with dustproof protective structures on their outer sides to prevent external dust and impurities from entering the mating gaps. During equipment operation, the sliding transmission structure can be cleaned and lubricated regularly to ensure the sliding and transmission accuracy of the structure.

[0032] This application can be used in the field of new energy charging equipment, or in other fields applicable to this application.

[0033] In another embodiment: Reference Figures 1-9A modular quick-change charging pile for new energy vehicles with a guide rail structure is used in the field of new energy charging equipment. The structure of this embodiment is basically the same as that of the previous embodiment, except that: two sets of symmetrically arranged limiting side plates I 30 are fixedly assembled on the inner side wall of the sealing baffle 5, and a horizontally arranged supporting base plate 31 is fixedly assembled at the bottom of the limiting side plate I 30. Two sets of symmetrically arranged limiting side plates II 34 are fixedly assembled on the bottom inner wall of the rectangular cavity 9. A planar sliding groove 38 is opened on one side of the top of the limiting side plate II 34, and one end of the planar sliding groove 38 is connected to an inclined sliding groove 39. A strip groove 32 is opened on the bottom side wall of the limiting side plate II 34, and the groove structure of the strip groove 32 matches the supporting base plate 31. Two sets of symmetrically arranged moving wheels 35 are rotatably assembled on both sides of the mounting shell 36. The moving wheels 35 can form a rolling engagement with the supporting base plate 31, the inclined sliding groove 39, and the planar sliding groove 38, respectively. Under abnormal high-temperature conditions, the servo motor 18 drives the lead screw 14 to rotate, causing the support L-shaped plate 33 and the push side plate 37 to move laterally. After the push side plate 37 disengages from the contact position of the mounting housing 36, the return spring 19 pushes the mounting housing 36 to move, and the moving wheel 35 rolls along the planar slide groove 38, realizing the rapid separation of the connector 43 and the connector hole 12. At this time, the push side plate 37 stops at the limit position of the planar slide groove 38, limiting the movement stroke of the mounting housing 36, and only completing the electrical separation and risk avoidance. Under normal maintenance and replacement conditions, the servo motor 18 continues to work, driving the push side plate 37 to continue to move, releasing the travel restriction on the mounting housing 36. The return spring 19 continues to push the mounting housing 36 to move, causing the moving wheel 35 to slide to the position of the inclined slide groove 39 and slide down along the groove, finally causing the mounting housing 36 to fall above the support base plate 31, completing the smooth removal of the power module 51, which facilitates subsequent maintenance and replacement operations.

[0034] Based on the above structural design, the equipment can achieve automated temperature detection and emergency power failure protection. At the same time, through multi-level guiding and limiting structures, it can adapt to both emergency avoidance and routine maintenance working modes. With the adjustable mechanical limiting structure and sealed sliding structure, the equipment can ensure operational safety while effectively improving the convenience of power module disassembly and maintenance and the overall adaptability of the equipment to operating conditions.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller, temperature sensor, and servo motor 18 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
